Streszczenie:
The micro-canonical, canonical, and grand canonical ensembles of walks defined in finite connected undirected graphs are considered in the thermodynamic limit of infinite walk length. As infinitely long paths are extremely sensitive to structural irregularities and defects, their properties are used to describe the degree of structural imbalance, anisotropy, and navigability in finite graphs. For the first time, we introduce entropic force and pressure describing the effect of graph defects on mobility patterns associated with the very long walks in finite graphs; navigation in graphs and navigability to the nodes by the different types of ergodic walks; as well as node’s fugacity in the course of prospective network expansion or shrinking.

Streszczenie:
Background. For survival of the organism, T cells must efficiently control pathogens invading different peripheral tissues. Whether or not such control is achieved by utilizing different movement strategies in different tissues remains poorly understood. Liver-localized CD8 T cells perform correlated random walks --- a type of a Brownian walk -- in liver sinusoids but in some condition these T cells may also perform Levy flights -- rapid and large displacements by floating with the blood flow. CD8 T cells in lymph nodes or skin also undergo Brownian walks. A recent study suggested that brain-localized CD8 T cells, specific to Toxoplasma gondii, perform generalized Levy walks -- a walk type in which T cells alternate pausing and displacing long distances --- which may indicate that brain is a unique organ where T cells exhibit movement strategies different from other tissues. Methods. We quantified movement patterns of brain-localized Plasmodium berghei-specific CD4 and CD8 T cells by using well-established statistical and computational methods. Results. We found that T cells change their movement pattern with time since infection and that CD4 T cells move faster and turn less than CD8 T cells. Importantly, both CD4 and CD8 T cells move in the brain by correlated random walks without long displacements challenging previous observations. We have also re-analyzed the movement data of brain-localized CD8 T cells in T. gondii-infected mice and found no evidence of Levy walks. We hypothesize that the previous conclusion of Levy walks of T. gondii-specific CD8 T cells in the brain was reached due to missing time-frames in the data that create an impression of large movement lengths between assumed-to-be-sequential movements. Conclusion. Our results suggests that movement strategies of CD8 T cells are largely similar between LNs, liver, and the brain and consistent with correlated random walks and not Levy walks.

Streszczenie:
Hanoi network (HN) has a one-dimensional periodic lattice as its main structure with additional long-range edges, which allow having efficient quantum walk algorithm that can find a target state on the network faster than the exhaustive classical search. In this paper, we use regular quantum walks and lackadaisical quantum walks, respectively, to search for a target state. From the curve fitting of the numerical results for HN of degrees three and four, we find that their running time for the regular quantum walks are followed by amplitude amplification scales as [Formula: see text] and [Formula: see text], respectively. For the search by lackadaisical quantum walks, the running time scales are as [Formula: see text] and [Formula: see text], respectively.

Streszczenie:
Lévy walks are random walk processes whose step lengths follow a long-tailed power-law distribution. Because of their abundance as movement patterns of biological organisms, substantial theoretical efforts have been devoted to identifying the foraging circumstances that would make such patterns advantageous. However, despite extensive research, there is currently no mathematical proof indicating that Lévy walks are, in any manner, preferable strategies in higher dimensions than one. Here, we prove that in finite two-dimensional terrains, the inverse-square Lévy walk strategy is extremely efficient at finding sparse targets of arbitrary size and shape. Moreover, this holds even under the weak model of intermittent detection. Conversely, any other intermittent Lévy walk fails to efficiently find either large targets or small ones. Our results shed new light on the Lévy foraging hypothesis and are thus expected to affect future experiments on animals performing Lévy walks.

Long heritage management related activities have been studied by sociologist, heritage management experts, anthropologists and architects and artists. Researchers felt importance of using management theories in heritage management research domain. This paper tries to focus on this call for research. It aims to study the value network in heritage walk organisations for creating shared value - a form of value that Porter and Kramer describe, in placing social and community needs before profit. It studies value network in three heritage walks organized by three organisations in Ahmedabad city in western part of India. It covers three cases studies of these walks that cover architecture, communities, craft, food and other elements of living and non-living heritage. This study is exploratory in nature. It shows the impact of these walks on various stakeholders under nine dimensions of value network framework.

Streszczenie:
The question of whether quantum spatial search in two dimensions can be made optimal has long been an open problem. We report progress towards its resolution by showing that the oracle complexity for target location can be made optimal, by increasing the number of calls to the walk operator that incorporates the graph structure by a logarithmic factor. Our algorithm does not require amplitude amplification. An important ingredient of our algorithm is the implementation of multi-step quantum walks by graph powering, using a coin space of walk-length dependent dimension, which may be of independent interest. Finally, we demonstrate how to implement quantum walks arising from powers of symmetric Markov chains using our methods.

Streszczenie:
Previously, for predicting coding regions in nucleotide sequences, a self-adaptive spectral rotation (SASR) method has been developed, based on a universal statistical feature of the coding regions, named triplet periodicity (TP). It outputs a random walk, that is, TP walk, in the complex plane for the query sequence. Each step in the walk is corresponding to a position in the sequence and generated from a long-term statistic of the TP in the sequence. The coding regions (TP intensive) are then visually discriminated from the noncoding ones (without TP), in the TP walk. In this paper, the behaviors of the walks for random nucleotide sequences are further investigated qualitatively. A slightly leftward trend (a negative noise) in such walks is observed, which is not reported in the previous SASR literatures. An improved SASR, named the mature SASR, is proposed, in order to eliminate the noise and correct the TP walks. Furthermore, a potential sequence pattern opposite to the TP persistent pattern, that is, the TP antipersistent pattern, is explored. The applications of the algorithms on simulated datasets show their capabilities in detecting such a potential sequence pattern.

Streszczenie:
<p> The act of thru-hiking a long-distance trail immerses hikers in the natural world for an extended time; as such, it represents a compelling system to study the relationships between a specific appreciative activity&mdash;thru-hiking&mdash;and environmental attitudes regarding sustainability. This thesis critically explored the primary research question: How do thru-hikes change or inspire environmental attitudes in thru-hikers on long-distance trails in the United States? I employed the revised NEP scale to survey 98 thru-hikers using snowball sampling and I interviewed a subset to gain more in-depth knowledge. In addition, I textually analyzed the blogs written by thru-hikers. Findings suggest that environmental attitudes of thru-hikers already leaned in an ecocentric direction before thru-hiking and after thru-hiking, their environmental attitudes became more so. Furthermore, this thesis finds that women had more ecocentric views than men before and after thru-hiking and that more ecocentric attitude change occurred for thru-hikers in their twenties than other age groups. Thru-hikers also chose to express their environmental views through conversations and their actions. And thus, thru-hikes on long-distance trails in the United States have the potential to strengthen and/or reinforce existing ecocentric attitudes in thru-hikers.</p>

Streszczenie:
In this thesis we study mean field interacting particle systems and their McKean-Vlasov limiting processes, in particular we focus on three different interaction mechanisms, mainly emerging from biological modelling. The first type of interaction is given by the so called simultaneous jumps. We consider a system of interacting jump-diffusion processes that interact by means of the discontinuous component: each particle performs a main jump and it simultaneously induces in all the other particles a simultaneous jump whose amplitude is rescaled with the size of the system. This peculiar interaction is motivated by recent neuroscience models and here we depict a general framework for this type of processes. We focus on the well-posedness of the McKean-Vlasov limits of these particle systems under different assumptions on the coefficients and we prove a pathwise propagation of chaos result. The second interaction we consider is an asymmetric one. We describe a system of biased random walks on the positive integers, reflected at zero, where each particle may perform a leftward jump with a rate proportional to the fraction of particles which are strictly at its left. We study the critical interaction strength able to ensure ergodicity to this system, that would be transient in absence of interaction. We compare this model with existing models of diffusions interacting through their CDF and we highlight their differences, mainly caused by the presence of clusters of particles in the discrete model. The third interaction we account for is based on a dynamical version of the generalized Curie-Weiss model. We modify a Langevin dynamics for this model with a dissipative evolution of the interaction component, breaking the reversibility of the system. We prove that, in the mean field limit, this gives rise to stable limit cycles, explaining self-sustained periodic behaviors. In particular, we build a flexible model in which a suitable change in the interaction function can result in a system which, in certain regimes of parameters, displays coexistence of stable periodic orbits.<br>L’argomento di questa tesi sono i sistemi di particelle con interazione a campo medio e i processi nonlineari ottenuti come limiti di essi. Il lavoro è suddiviso in tre parti, in cui vengono analizzati modelli caratterizzati da tre diversi meccanismi di interazione. Nella prima parte ci occupiamo di un’interazione tramite salti simultanei, che prende spunto da alcuni modelli apparsi recentemente in neuroscienze, dove gli autori trattano sistemi di neuroni in comunicazione l’uno con l’altro. Con l’obiettivo di generalizzare questo tipo di modelli consideriamo un sistema di diffusioni con salti che interagiscono tra loro attraverso la componente discontinua: ogni processo compie un salto principale con una certa frequenza e, contemporaneamente, forza tutte le altre particelle a compiere anch’esse un salto che però è detto salto collaterale, in quanto viene riscalato rispetto alla taglia del sistema. Considerando diverse ipotesi sui coefficienti, ci concentriamo sulla propagazione del caos traiettoriale e sulla dimostrazione di esistenza e unicità delle soluzioni per la corrispondente SDE nonlineare. Nella seconda parte della tesi ci occupiamo di un’interazione di tipo asimmetrico. Definiamo un sistema dove ogni particella si muove secondo una passeggiata aleatoria sui naturali, riflessa in zero e con un eventuale drift verso destra. In aggiunte c’è un’interazione asimmetrica, nel senso che ogni particella viene spinta a compiere movimenti verso sinistra sotto l’influenza solo delle particelle che si trovano alla sua sinistra. Ci chiediamo come questo sistema, che in assenza di interazione è transiente, possa diventare ergodico a seconda della forza dell’interazione e studiamo i parametri critici sia nel sistema ad N particelle che nel suo limite termodinamico. In particolare sfruttiamo risultati esistenti su diffusioni che interagiscono attraverso la funzione cumulativa empirica per evidenziare le differenze date dalla dinamica discreta. Nella terza parte ci concentri- amo su una dinamica di Langevin per il modello di Curie-Weiss generalizzato alla quale applichiamo un termine di dissipazione. Questo approccio è stato precedentemente usato per rompere la reversibilità nel modello di Curie-Weiss classico ed è stato dimostrato che, in quel caso, il sistema limite ammette una soluzione periodica. Il nostro lavoro conferma l’emergenza di comportamenti periodici anche nel caso del Curie-Weiss generalizzato. In particolare, possiamo dimostrare che un’accurata scelta della funzione di interazione nel modello di partenza è tale da dare luogo ad un sistema limite in cui coesistono molteplici soluzioni periodiche stabili.

Long Walk in Flight School is a document intended to complement a body of artwork that includes photographs, giclee prints, animation, and a twenty two page book of images. The main focus of the text is to discuss two types of exchange; my energy with tools in exchange for an object or event, which is then exchanged in the imagination of the audience for something else, a hybrid thing. These exchanges are part of the performance or presentation of the work. Beginning with a brief description of intent at the start of graduate school, it traces my development as an artist over a two year period, highlighting shifts in my thinking and activity during that time. Finally, it describes my thesis artwork as a set of potential narratives that are conceptually related but visually diverse.

Streszczenie:
The effect of door and window openings on long timber framed shear walls was the subject of this thesis. Four different wall configurations containing various openings and one control wall with no openings were tested to examine ultimate load capacity and stiffness. All walls were forty feet in length and contained tie-down anchorage at the extreme ends of the wall only. Two replications of the five wall configurations were built. Each of the five wall configurations was tested using a: 1) monotonic displacement pattern and 2) sequential phased displacement pattern. A better understanding of the effect of monotonic and cyclic loading (and the relationship between the two loading types) on ultimate load capacity and stiffness for a given wall configuration were examined. To efficiently design shear walls, the effect of openings on shear wall performance must be known. This thesis adds to previous work on shear walls with openings to provide valuable information for future use. Results from this investigation are intended to provide useful information regarding performance of long shear walls with openings. Data concerning capacity, drift, elastic stiffness, and ductility are presented. Two methods of capacity prediction of shear walls with openings are examined. Sugiyama (1994) provided an empirical equation for prediction of load resistance that has been applied to capacity and is the basis for the perforated shear wall method. This thesis further validates his work to full scale long shear walls. A new method for capacity prediction was developed by the author and is also presented.<br>Master of Science

Streszczenie:
The study area extends from west of the Great Divide to the Broken Hill and Tibooburra regions of far western New South Wales, encompassing several important mining districts that not only include the famous Broken Hill lodes (Pb-Zn-Ag), but also Parkes (Cu-Au), Peak Hill (Au), Cobar (Cu-Au-Zn) and White Cliffs (opal). The area is generally semi-arid to arid undulating to flat terrain covered by sparse vegetation. ¶ During the Cretaceous, an extensive sea retreated across vast plains, with rivers draining from the south and east. After the uplift of the Great Divide associated with opening of the Tasman Sea in the Late Cretaceous, drainage swung to the west, cutting across the Darling River Lineament. The Murray-Darling Basin depression developed as a depocentre during the Paleogene. Climates also underwent dramatic change during the Cenozoic, from warm-humid to cooler, more seasonal climates, to the arid conditions prevalent today. Up until now, there has been very little temporal constraint on the development of this landscape over this time period. This study seeks to address the timing of various weathering and landscape evolution events in northwestern New South Wales. ¶ The application of various regolith dating methods was undertaken. Palaeomagnetic dating, clay δ18O dating, (U+Th)/He and U-Pb dating were all investigated. Palaeomagnetic and clay dating methods have been well established in Australian regolith studies for the last 30 years. More recently, (U+Th)/He dating has been successfully trialled both overseas and in Australia. U-Pb dating of regolith materials has not been undertaken. Each method dates different regolith forming processes and materials. Palaeomagnetic and clay dating were both successfully carried out for sites across northwestern New South Wales, providing a multi-technique approach to resolving the timing of weathering events. Although (U+Th)/He dating was unsuccessful, there is scope for further refinement of the technique, and its application to regolith dating. U-Pb dating was also unsuccessfully applied to late-stage anatase, which is a cement in many Australian silcretes. ¶ Results from this study indicate that the landscape evolution and weathering history of northwestern New South Wales dates back at least 60 million years, probably 100 million years, and perhaps even as far back as 180 million years. The results imply that northwestern New South Wales was continuously sub-aerially exposed for the last 100 Ma, indicating that marine sedimentation in the Murray-Darling and Eromanga-Surat Basins was separated by this exposed region. The ages also provide further evidence for episodic deep chemical weathering under certain climatic conditions across the region, and add to the data from across Australia for similar events. In particular, the palaeomagnetic ages, which cluster at ~60 ± 10 Ma and 15 ± 10 Ma, are recorded in other palaeomagnetic dating studies of Australian regolith. The clay ages are more continuous across the field area, but show older clays in the Eromanga Basin sediments at White Cliffs and Lightning Ridge, Eocene clays in the Cobar region, and Oligocene – Miocene clays in the Broken Hill region, indicating progressively younger clay formation from east to west across northwestern New South Wales, in broad agreement with previously published clay weathering ages from around Australia. ¶ These weathering ages can be reconciled with reconstructions of Australian climates from previously published work, which show a cooling trend over the last 40 Ma, following an extended period of high mean annual temperatures in the Paleocene and Eocene. In conjunction with this cooling, total precipitation decreased, and rainfall became more seasonal. The weathering ages fall within periods of wetness (clay formation), the onset of seasonal climate (clay formation and palaeomagnetic weathering ages) and the initiation of aridity in the late Miocene (palaeomagnetic weathering ages). ¶ This study provides initial weathering ages for northwestern New South Wales, and, a broad geochronology for the development of the landscape of the region. Building on the results of this study, there is much scope for further geochronological work in the region.

Streszczenie:
In this investigation, thirty-six shear walls measuring 8 feet (2.4 m) in width and possessing heights of 8, 9 and 10 feet (2.4, 2.7 and 3.0 m) were subjected to the reversed, cyclic loading schedule of the standard CUREE protocol in order to determine the performance capabilities of shear walls greater than 8 feet (2.4 m) in height sheathed with long panels. Of the thirty-six walls, a total of twelve walls measuring 9 and 10 feet (2.7 and 3.0 m) in height were sheathed with 4 x 8 feet (1.2 x 2.4 m) panels which required additional blocking members between the studs of the frame. Values obtained from the tests performed on these walls provided a direct comparison to those obtained from the walls of equal height, but sheathed with a long panel capable of spanning the entire height of the wall. The capabilities of long panels were investigated when used as the sheathing elements of shear walls with and without a mechanical hold-down device attached to the base of the end stud. An advantage of the long panel was investigated in which it was extended past the bottom plate and down onto the band joist to determine if significant resistance to the uplift present in walls without mechanical hold-down devices could be provided. Also, the effects of orienting the fibers of a 4 x 9 feet (1.2 x 2.7 m) panel in the alternate direction were examined. Average values of the parameters produced by walls sheathed with long panels either matched or exceeded those of its counterpart sheathed with 4 x 8 feet (1.2 x 2.4 m) panels in all configurations except the 10 feet (3.0 m) tall wall without hold-down devices. In fact, 4 x 9 feet (1.2 x 2.7 m) panels increased the performance of 9 feet (2.7 m) tall walls equipped with hold-down restraint significantly. Extending the long panels past the bottom plate and down onto the band joist improved the performance of both 8 and 9 feet (2.4 and 2.7 m) tall prescriptive shear walls significantly. Walls sheathed with panels made of fibers oriented in the alternate direction performed identically to those sheathed with panels of typical fiber orientation until the point of peak load. Once peak load was reached, walls sheathed with panels of alternate oriented fibers failed in a more sudden and brittle manner.<br>Master of Science

Abstract Mechanically stabilized earth walls, MSEW, around Florida were instrumented through their concrete covers to survey corrosion rates of galvanized strip soil reinforcement by polarization measurements. The first broad survey was made 10 years ago as a baseline and a new survey is currently underway to assess long term corrosion rate trends. Initial results of an ongoing survey confirm low rates consistent with controlled backfill composition.

The extensive network of engineering protection of the territory of the Kyiv-Pechersk Lavra against the impact of hazardous processes (landslides, flooding) includes more than 5 km of retaining walls (brick, concrete, pile-based) and about 12 km of drainage networks (tunnel, gallery, and radial types). The effectiveness of the drainage adit systems (DAS) on the Upper Lavra and the radial drainage on the territory of the Guest Yard (Inn Courtyard) of the Lower Lavra was analyzed. The paper proposes an assessment of the efficiency of drainage adit systems according to such criteria as the specific flow rate q (m3/day) and the specific removal of sediments v (m3/year) into the tunnel, the efficiency is determined as poor (q=0.001...0.02, v=0.11...0.2), sufficient (q=0.021...0.1, v=0.017...0.1), or high (q=0.11...0.5, v=0.011...0.016). Patterns of groundwater supply, the lithological composition of the transported material, exogenous geological processes occurring in drainage areas, the amount of groundwater flow reaching the surface, and technical aspects of drainage system were analyzed. The results were obtained based on the analysis of the measured flow rates and data on sediment removal from 1980 to 1990. The efficiency of DAS-28 is assessed as sufficient and high. The effectiveness of radial drainage is measured as the flow rate of groundwater levels in monitoring boreholes and the reduction of moisture content in building structures. On the territory of Guest Yard, as a result of the work of radial drainage, the groundwater levels in monitoring boreholes dropped by 0.6-0.9 m, the moisture content of masonry walls reached the control level (4-6 %), periodic flooding with meltwater stopped. Monitoring observations for 2006-2023 were analyzed as well.

Abstract After 39 years of operation, the orifice plate in a black liquor incinerator reactor has seen over 250,000 hours of exposure to operating temperatures in the range of 480-595°C (900-1100°F), and has cracked in numerous locations. This article describes the results of a metallurgical evaluation of plate samples removed from the unit. Although a 0.5Cr-0.5Mo high-temperature alloy was used for the orifice plate, this evaluation showed that the orifice plate had undergone irreversible elevated temperature degradation of its mechanical properties, in addition to the cracking observed. High temperature degradation mechanisms found in the plate include: creep, thermal fatigue, surface cracking, grain growth, temper embrittlement, and low toughness at temperatures below 85°C (185°F). A fracture mechanics evaluation of the plate subjected to the operating stresses and the effects of the existing cracks showed that static loads alone would not induce brittle crack growth and the plate would not collapse. However, below 85°C (185°F) impact loads could be high enough to trigger brittle fracture and a collapse of the orifice plate. Impact loads could originate from process material build-up falling from walls of the reactor chamber or by a power loss where the fluidized bed suddenly rests on top of the plate.

Abstract Corrosion is the primary cause of repairs to reinforced concrete bridges and other civil structures. Galvanic corrosion protection systems have been developed to provide long-term corrosion protection to existing concrete structures suffering from corrosion. Through the partnership and support of structure owners such as Ohio Department of Transportation, Ontario Ministry of Transportation, Florida Department of Transportation and Transport New South Wales these systems have been installed and monitored on bridge decks and substructures for many years. Some of these structures have been monitored for over 20 years. This paper presents the development, installation and 20-year field performance of these galvanic corrosion protection systems and how this real-world performance data can be used to design long-life galvanic corrosion protection systems to extend the service life of reinforced concrete structures.

Проведены эксперименты по распространению вихревых лазерных пучков на атмосферной трассе длиной 500 метров. Рассмотрено уширение лазерного пучка в конце трассы распространения в зависимости от величины топологического заряда. Показано, что случайные блуждания вихревых оптических пучков не зависят от величины топологического заряда, а определяются их начальными пространственными размерами и величиной структурной характеристики показателя преломления. Experiments on the propagation of vortex laser beams on an atmospheric path 500 meters long have been carried out. The broadening of the laser beam at the end of the propagation path is considered depending on the magnitude of the topological charge. It is shown that the random walks of vortex optical beams do not depend on the magnitude of the topological charge, but are determined by their initial spatial dimensions and the magnitude of the structural characteristic of the refractive index.

This critical reading seeks to provide a comprehensive analysis of some of the most popular teaching modalities, their characteristics, and models. Some of their advantages and challenges are also addressed. Understanding the distinctions among these educational models is necessary for educators from all walks of life. This is especially true for higher education settings where administrators, teaching staff and student population are expected to innovate and to succeed in emerging learning environments. Taking this into account, face-to-face, long distance, and online education are described. A brief description of different online or e-learning modalities is also offered. It also includes an in-depth explanation of what B-learning, a model widely used at UCC, is about, its models and its advantages and disadvantages. One conclusion is that learning about the fundamental aspects of each of these learning modalities can help both teachers and students to make the most of them and, therefore, improve both teaching practices and learning outcomes. B-learning has emerged as a solution for the institutions and teachers who are willing to innovate through the use of emerging technologies applied in both face-to-face and online educational interactions.

This research report is a case study on local peace practices within pastoralist communities in Kenya’s Turkana North (a subcounty of Kenya’s Turkana County). While significant existing research and analysis has focused on the concern that pastoralist communities across the African continent may contribute to growing violent conflict—and in particular to violent extremism—this report instead situates these communities within the theoretical framework of “everyday peace.” This framework centers on understanding the myriad ways in which ordinary people in conflict-affected contexts engage in small acts of peace and forge pro-social relationships that contribute to peace and stability within their communities. This report explores these everyday practices of peace within pastoralist communities in Kenya’s Turkana County, and Turkana North subcounty, a borderland territory that connects Ethiopia, South Sudan, and Uganda with a long history of conflict around inter-clan livestock raiding and cross-border movement/land access. Informed by a multi-method research methodology that included semi-structured interviews, focus groups, historical profiling, transect walks, and non-participant observational data collected in August 2022, the findings from this study highlight both the existing local systems and resources for peacebuilding and conflict mitigation in pastoralist communities in Turkana, as well as the stressors and challenges that affect them. Lessons from this research contribute to our broader understanding of how policymakers and practitioners can work to better assess and coordinate violence prevention and reduction efforts in light of specific pastoralist needs and everyday practices of peace, particularly in areas impacted by violent conflict and/or violent extremism where pastoralist communities exist.

Processes for moisture concentration and temperature at different depths in a rather thick wall with mineral wool insulation are studied with a resolution of 1 minute. Damp processes in walls with thick layers of mineral wool differs a lot depending on the weather conditions. Any modelling of heat and moisture in building constructions need to consider this. The fact that the peaks in moisture concentration in some cases come hours before the peak in temperature is something that takes an explanation. It is possible, but not really sure, that this also may have influence on the risk for damage on the structures.

We use long-run annual cross-country data for 10 macroeconomic variables to evaluate the long-horizon forecast distributions of six forecasting models. The variables we use range from ones having little serial correlation to ones having persistence consistent with unit roots. Our forecasting models include simple time series models and frequency domain models developed in Müller and Watson (2016). For plausibly stationary variables, an AR(1) model and a frequency domain model that does not require the user to take a stand on the order of integration appear reasonably well calibrated for forecast horizons of 10 and 25 years. For plausibly non-stationary variables, a random walk model appears reasonably well calibrated for forecast horizons of 10 and 25 years. No model appears well calibrated for forecast horizons of 50 years.

Reinforced soil walls are key earth retention features in the transportation infrastructure. They are used to support and retain soil in a wide variety of crucial structures, such as highways, bridges, and railways, to ensure stability. They also provide solutions for constructing embankments and slopes in constrained spaces, allowing for efficient land use and improved infrastructure planning. This study used advanced numerical modeling to improve the understanding of the behavior and long-term performance of the aging reinforced soil walls from the 1970s for asset management purposes. An asset-scale model was created to simulate the effects of weather on these walls. The model included a system to track how moisture-driven corrosion affects wall stability and performance over time. The model outputs provide implications on the wall progressive deterioration over time and estimates for the wall remaining service life. Unlike newer wall generations constructed with strict specifications that limit fill corrosivity, early wall generations may maintain high levels of moisture for prolonged periods that can significantly increase corrosion rates. Accordingly, it is recommended that fill moisture monitoring be added to asset management measures for early generation walls that could have been constructed with highly corrosive or poorly drainable fills. The results of this study indicate that even though corrosion rates vary with changes in fill moisture, the overall loss in reinforcement thickness happens at a steady rate, showing a linear relationship between cumulative corrosion and time. The results also indicate that 25% fluctuation in fill moisture has no to little effect on the cumulative corrosion, and that the average fill moisture can be used to predict an approximate long-term cumulative corrosion. Thus, it is recommended to use one year of seasonal climate data for a specific location to estimate the annual variation in fill moisture. This can predict the yearly corrosion of reinforcements, which can then be multiplied by the number of service years to estimate long-term cumulative corrosion. Finally, an asset-scale performance model based on performance-requirement failure framework was developed using the outputs of the asset-scale numerical model. These performance models can inform decisions about critical transportation infrastructure maintenance, repair, or replacement strategies, and optimizing resource allocation.

The New River Gorge National River was established by Congress in 1978, the New River Gorge National Park and Preserve (NERI) was established more recently in December 2020. Recreational climbers have been using the Gorge and surrounding areas since the early 1970s. As visitation has increased, NERI has become interested in documenting the presence of bat species and their habitat on and near the cliff face, rim, and base areas to support a park management plan. A total of 51 routes were selected to survey three times throughout the summer of 2022. Cliff line surveys included personnel on-rope rappelling down each selected cliff face to look for bats or bat sign and to collect data on the physical attributes and record habitat information. In addition, a simultaneous acoustic survey for bats was conducted at the base of each survey route. Although no bats or bat sign were documented, analysis of the acoustic data in concert with the environmental factors revealed that bats were detected at more highly climbed walls versus unclimbed walls. Northern long-eared bats (Myotis septentrionalis) were more likely to be detected near less vegetated walls and activity of eastern small-footed bats (Myotis leibii) was higher as the summer progressed.

Streszczenie:
Reinforced concrete structural slurry walls have been used in the United States since the early 1960s. The typical practice, and one that makes the economics of slurry walls particularly attractive, is to design the walls to act as both temporary excavation support and permanent basement walls. They often serve as multi-story basements and below grade parking for buildings, for tunnels, subway stations, and other buried structures. One of the early applications was for a foundation for a subway station in San Francisco, but for the most part they have been used more extensively in regions of low seismicity. The purpose of this report is to investigate the requirements for extension of this practice to more common use in regions of high seismicity. Structural slurry walls are concrete walls constructed below the ground surface. In slurry wall construction, a trench is excavated using a rectangular clamshell bucket or other specialized equipment. During excavation, the trench is held open by introduction of a bentonite or polymer slurry. Steel reinforcement, if required, is lowered into the slurry-filled trench, and concrete is subsequently deposited by tremie, displacing the slurry. The length of trench open at any one time is limited to a typical maximum of about 20 to 24 feet by excavation stability and concrete placement volume considerations. Each individual concrete placement is referred to as a “panel,” and vertical construction joints separate the panels. Temporary “end-stops” are used as formwork to control the geometry of the panel joints, and horizontal reinforcement is discontinuous at the joints. Structural slurry panels range from 1.5 to 5.0 feet thick, 7 to 24 feet long, and up to 300 feet deep. In the United States, panels that are 2.0 to 3.5 feet thick and depths of 40 to 150 feet are commonplace. Structural basement walls support earth pressures acting laterally against the wall, dead and live loads acting vertically, and in-plane shear and flexure from wind and earthquake loads. The design of permanent slurry walls in regions of low or moderate seismicity is often limited to providing the strength necessary to resist out-of-plane soil pressures and vertical dead and live loads from the superstructure and basement framing. Although these walls also transfer in-plane lateral forces from the superstructure into the soils, the walls are often not specifically designed for these in-plane forces because their inherent strength is usually much greater than the forces being transferred. If resistance to in-plane forces acting on a wall required an increase in vertical reinforcement at the ends of a wall segment, an increase in the cap beam strength, or an increase in the horizontal reinforcement for shear strength, the overall design and construction approach would not vary significantly from current practice. Structural slurry walls have been used to a limited extent for buildings designed for high seismic risk, but there is reluctance on the part of design engineers to use them more often because of concern for how to design these walls to resist in-plane lateral forces, lack of code provisions for reinforcement detailing, and damage that may occur at panel joints. For buildings designed for high seismic risk, such as those assigned to Seismic Design Categories (SDC) D, E, and F as defined in Minimum Design Loads for Buildings and Other Structures (ASCE/SEI 7-10), in-plane shear and flexural actions may likely require modifications of a structural slurry wall only designed for out-of-plane soil pressures and vertical live and dead loads. Design would need to address in-plane lateral forces acting on structural slurry walls and the interaction of the in-plane actions with the out-of-plane and vertical actions. These issues are discussed in this report, and approaches to design for high seismic risk are presented.

Streszczenie:
Problem-solving courts (PSC) are a problem-solving approach targeting the complex needs of individuals within the criminal or family justice systems. Over the last 20 years, PSC have been introduced into the UK to address the personal, social and structural factors underlying behavioural issues that often contribute to re-offending. In June 2023, the Ministry of Justice launched three courts with problem-solving components referred to as Intensive Supervision Courts (ISC). Focusing on rehabilitative outcomes, PSC combine intervention programmes with judicial oversight through regular reviews. By placing judges and magistrates at the centre of rehabilitation, PSC target individuals or families with complex needs, who might not benefit from standard court proceedings and supervision, with an aim to improve long-term life outcomes. This POSTnote provides an overview of PSC in England and Wales. It outlines different PSC and courts with PSC elements that operate within adult criminal courts, family courts and youth courts across England and Wales, drawing data from case studies in the UK and, where relevant, internationally. It also discusses potential challenges to fully implement PSC and their approaches as well as opportunities for more effective implementation of PSC across England and Wales. Key points Key elements of PSC include intensive intervention programmes, that seek to address underlying social and health issues through regular judicial monitoring and cross-governmental collaborative efforts. Several ongoing PSC and courts with PSC elements operate within adult criminal courts, family courts and youth courts across England and Wales. Although there is a substantial international evidence base, there seems to be limited evidence about the effectiveness of PSC in the UK due to inconsistent implementation and evaluation. Challenges to PSC implementation can include costs, lack of funding, limited evidence, procedural issues and lack of widespread judicial engagement. Opportunities for effective PSC implementation include use of existing resources, multi-agency partnerships, advocating for specialist services and a change in culture within the judiciary.

The Caribbean islands are among the 25 most-vulnerable nations in terms of disasters per-capita or land area, and climate change is only expected to intensify these vulnerabilities. The loss caused by climate events drags the ability of the Caribbean countries to invest in infrastructure and social programs, contributing to slower productivity growth, poorer health outcomes, and lower standards of living. Within this context, building resiliency should become a priority for the Caribbean countries. The series “Building a more resilient and low-carbon Caribbean”, focuses on improving the resiliency, sustainability and decarbonization of the construction industry in the Caribbean. The results show that increasing building resiliency is economically viable for the high-risk islands of the Caribbean, generating long term savings and increasing the infrastructure preparedness to the impacts of CC. Report 1 - Climate Resiliency and Building Materials in the Caribbean, presents a quantification of the economic losses caused by climate impact events in the Caribbean Region and correlate these figures with the most common construction materials, typically used in each of the countries building typologies. The losses caused by hurricanes concentrate mostly in the residential infrastructure and are mainly caused by weaknesses in roofs and their connection to the walls. The analysis suggests that improving the resiliency of outer walls and roofs in the Caribbean could significantly reduce the regions vulnerability to hurricanes and other climate impacts.
