The classical regenerative method of simulation output analysis exploits the regenerative structure of a stochastic process to break up a path into independent and identically distributed cycles based on a single sequence of regeneration times. If a process is regenerative with respect to more than one sequence of regeneration times, the classical regenerative method does not exploit the additional structure, and the variance of the resulting estimator for certain performance measures (e.g., the time-average variance constant) can vary greatly, depending on the particular regeneration sequence chosen. In a previous article, we introduced an efficiency-improvement technique for regenerative simulation of processes having two sequences of regeneration times based on permuting regenerative cycles associated with the second sequence of regeneration points. In this article, we show how to exploit more than two regeneration sequences. In particular, for birth–death Markov chains, the regenerations associated with hitting times to each state can all be exploited. We present empirical results that show significant variance reductions in some cases, and the results seem to indicate that the permuted estimator for the time-average variance constant can have a variance that is independent of the primary regeneration sequence used to run the simulation.

The force model of pavement structure is established. In order to investigate the force on pavement when the ratio and thickness of cold recycled pavement vary, three concrete pavement structures, material parameters and vehicle load parameters are designed. By finite element analysis, type 2 pavement structure make the cold-regenerative pavement structure anti-XY surface shear stress, anti-Z compressive stress and anti-Z deformation three aspects are kept in a reasonable range, and it is considered that the cold regenerative pavement structure type 2 is the best. Type 2 is specifically composed of 8 cm new asphalt surface layer +20 cm no stabilized soil regeneration base +20 cm stabilized soil regeneration base + original road soil base. The results of this paper can provide some reference for the actual design of emulsified asphalt cold regeneration construction process.

The review considers the molecular, cellular, organismal, and ontogenetic properties of Urodela that exhibit the highest regenerative abilities among tetrapods. The genome specifics and the expression of genes associated with cell plasticity are analyzed. The simplification of tissue structure is shown using the examples of the sensory retina and brain in mature Urodela. Cells of these and some other tissues are ready to initiate proliferation and manifest the plasticity of their phenotype as well as the correct integration into the pre-existing or de novo forming tissue structure. Without excluding other factors that determine regeneration, the pedomorphosis and juvenile properties, identified on different levels of Urodele amphibians, are assumed to be the main explanation for their high regenerative abilities. These properties, being fundamental for tissue regeneration, have been lost by amniotes. Experiments aimed at mammalian cell rejuvenation currently use various approaches. They include, in particular, methods that use secretomes from regenerating tissues of caudate amphibians and fish for inducing regenerative responses of cells. Such an approach, along with those developed on the basis of knowledge about the molecular and genetic nature and age dependence of regeneration, may become one more step in the development of regenerative medicine

Skeletal muscle regeneration depends on the satellite cells, which, in response to injury, activate, proliferate, and reconstruct damaged tissue. However, under certain conditions, such as large injuries or myopathies, these cells might not sufficiently support repair. Thus, other cell populations, among them adipose tissue-derived stromal cells (ADSCs), are tested as a tool to improve regeneration. Importantly, the pro-regenerative action of such cells could be improved by various factors. In the current study, we tested whether IL-4 and SDF-1 could improve the ability of ADSCs to support the regeneration of rat skeletal muscles. We compared their effect at properly regenerating fast-twitch EDL and poorly regenerating slow-twitch soleus. To this end, ADSCs subjected to IL-4 and SDF-1 were analyzed in vitro and also in vivo after their transplantation into injured muscles. We tested their proliferation rate, migration, expression of stem cell markers and myogenic factors, their ability to fuse with myoblasts, as well as their impact on the mass, structure and function of regenerating muscles. As a result, we showed that cytokine-pretreated ADSCs had a beneficial effect in the regeneration process. Their presence resulted in improved muscle structure and function, as well as decreased fibrosis development and a modulated immune response.

Regenerative medicine seeks to understand tissue development and homeostasis and build on that knowledge to enhance regeneration of injured tissues. By replenishing lost functional tissues and cells, regenerative medicine could change the treatment paradigm for a broad range of degenerative and ischemic diseases. Multipotent cells hold promise as potential building blocks for regenerating lost tissues, but successful tissue regeneration will depend on comprehensive control of multipotent cells–differentiation into a target cell type, delivery to a desired tissue, and integration into a durable functional structure. At each step of this process, proteins and small molecules provide essential signals and, in some cases, may themselves act as effective therapies. Identifying these signals is thus a fundamental goal of regenerative medicine. In this review we discuss current progress using proteins and small molecules to regulate tissue regeneration, both in combination with cellular therapies and as monotherapy.

The energy that traditional diesel particulate filter (DPF) regeneration with microwave requires in regeneration process often exceeds the capacity of the vehicle's battery, a rotary partition regenerative DPF with microwave is proposed recently, which was a annular column consisting of the fan-shaped filter units. A filtration unit microwave heating regeneration model was established aiming at this DPF, to study the regenerative properties of the filtration unit and to get influence that its shape structure plays on reproduction characteristics. The results show that: the central angle, length to diameter ratio, the ratio of inner and outer diameter of the DPF all have larger impact on the regeneration. The results can provide theoretical basis and reference for practical development of the new DPF.

Aging is associated with a significant decline of tissue repair and regeneration, ultimately resulting in tissue dysfunction, multimorbidity, and death. Salamanders possess remarkable regenerative abilities and have been studied with the prospect of inducing regeneration in humans and counteracting regenerative decline with aging. However, epimorphic regeneration, the full replacement of amputated structures, also occurs in mammals. One of the best studied models is digit tip regeneration, which is described for mice, and occurs in humans in a comparable manner. To accomplish regeneration, the amputated digit tip has to undergo three interdependent, overlapping steps: (i) wound healing without formation of a scar; (ii) formation of a blastema, a highly proliferative cell mass; and (iii) spatiotemporally regulated differentiation to generate a pattern similar to the original structure. Aging likely interferes with each of these steps. In this article, we provide an overview of the critical signaling pathways for regeneration, as revealed by investigating mammalian digit regeneration, the possible impact of aging on these pathways, and approaches to induce regeneration in the elderly. We hypothesize that with aging, increased Wnt signaling, NF-κB and tumor suppressor activity, and loss of positional information hampers regeneration. Knowledge about the impact of aging on regenerative mechanisms will enable us to safely activate endogenous regeneration in the elderly, and to generate a regeneration-permissive environment for cell therapies.

Synopsis In recent years, nonclassical models have emerged as mainstays for studies of evolutionary, developmental, and regenerative biology. Genomic advances have promoted the use of alternative taxa for the study of developmental biology, and the shark is one such emerging model vertebrate. Our research utilizes the embryonic shark (Scyliorhinus canicula) to characterize key developmental and regenerative processes that have been overlooked or not possible to study with more classic developmental models. Tooth development is a major event in the construction of the vertebrate body plan, linked in part with the emergence of jaws. Early development of the teeth and morphogenesis is well known from the murine model, but the process of tooth redevelopment and regeneration is less well known. Here we explore the role of the dental lamina in the development of a highly regenerative dentition in sharks. The shark represents a polyphyodont vertebrate with continuously repeated whole tooth regeneration. This is presented as a major developmental shift from the more derived renewal process that the murine model offers, where incisors exhibit continuous renewal and growth of the same tooth. Not only does the shark offer a study system for whole unit dental regeneration, it also represents an important model for understanding the evolutionary context of vertebrate tooth regeneration.

Urodele amphibians, such as the newtNotophthalmus viridescens, have the unique ability to regenerate limbs, spinal cord, eye structures, and many vital organs through a process called epimorphic regeneration. Although the cellular basis of regeneration has been studied in detail, we know relatively little about the molecular controls of the process. This review provides an overview of forelimb regeneration in the newt, addressing what we know about cellular and molecular aspects. Particular focus is placed on the dedifferentiation process, which yields a population of embryonic-like pluripotent cells that will eventually reform the lost structure. This cellular plasticity seems to be the key to regenerative ability. We discuss the dedifferentiation process in newt forelimb regeneration and outline the various studies that have revealed that mammalian cells also have the ability to dedifferentiate if given the appropriate triggers.

Specific aspects of nervous system structure, development, and regeneration were investigated in two separate studies. The first study was concerned with development of sensory root entry zones. Sensory information enters the central nervous system (CNS) via root entry zones where sensory axons span a glial environment consisting of Schwann cells in the peripheral nervous system (PNS) and astrocytes and oligodendrocytes in the CNS. Little is known about the postnatal development of the glial elements of many root entry zones. I sought to establish a comparative developmental timecourse of the glial elements in the postnatal (PO, P3, P7, P14) and adult rat of three root entry zones: the spinal nerve dorsal root entry zone, the trigeminal root entry zone, and the vagal dorsal root entry zone. I compared entry zone development based on the expression of antigens in peripheral glia, central glia, and the PNS extracellular matrix. While all three root entry zones had reached maturity by PI4, the glial elements comprising the PNS-CNS interface of the trigeminal root entry zone and the vagal dorsal root entry zone matured earlier than those of the spinal nerve dorsal root entry zone. This study revealed unexpected expression patterns of certain glial antigens. For example, the antibody used to label mature oligodendrocytes (RIP) labelled Schwann cell cytoplasm. I sought to follow up on this observation and characterized RTP immunoreactivity in peripheral glia in the second study. In uninjured rats, RIP demarcated paranodal regions of myelinated axons and clearly defined Schmidt- Lantermann incisures. Robust RIP immunoreactivity was present in Remak bundles. Low levels of RIP immunoreactivity were detectable in satellite cells surrounding dorsal root ganglion (DRG) neurons and in terminal Schwann cells at neuromuscular junctions. These results suggested a correlation between RIP immunoreactivity and amount of axoglial contact. Injury induced sympathetic sprouting and pericellular basket formation in the DRG was conducted to further examine this correlation. All perineuronal sympathetic sprouts infiltrated heavily RlP-immunoreactive satellite cell sheaths. RIP immunoreactivity was absent from placodal-derived olfactory ensheathing cells, suggesting that correlation between axoglial contact and RIP immunoreactivity is confined to peripheral glia of neural crest origin.

Abstract The aims were to examine the importance of regeneration by seeds, the influence of plant traits and disturbances, and the role of seed-seedling conflicts in regeneration and in the determination of vegetation structure. The study was carried out at in a subarctic alpine area (Kilpisjärvi 69°01'N 20°50E', Finland). Seed bank and seedling densities were high in many plant communities (ranges 99 -1109 viable seeds/m2 and 0.2-227 seedlings/m2, respectively). Effective seedling recruitment is reflected in vegetation as a high proportion of plants with poor or no vegetative reproduction ability. This development may take place in meadows and snowbeds where herbs (e.g. Gnaphalium supinum, Sibbaldia procumbens, Veronica alpina and Viola biflora) are abundant. On the other hand, the low proportion of these plants in heath vegetation reflects ineffective seedling recruitment. Floristic similarities between the consecutive phases in the regeneration pathway may be low despite effective seedling recruitment. Clonality, large and small seed sizes and appendaged diaspores limit the movement of species from phase to phase. Generally, disturbances facilitate effective regeneration by seeds. Grazing promotes species with large seed banks and is therefore one reason for high seed bank densities. Freezing and melting processes negate a negative influence of altitude on seed bank densities in the phase of seedlings. However, if disturbances are severe and continuous and the soil is compact, unstable or dry, disturbances are not beneficial. The same is true if there is a shift in the species composition of seedlings from gaps to closed vegetation. This phenomenon occurred in a rich meadow. Seed-seedling conflicts limit regeneration by seeds in low-herb snowbeds and Ranunculus glacialis-Gymnomitrion snowbeds. Vegetative reproduction and infrequent pulses of seedling recruitment negate an influence of short-term seedling recruitment on the spatial structure of vegetation. Extreme conditions, such as low temperatures, instability of the soil and late snowmelt modify the influence of factors that are important in more moderate conditions. To conclude, all transitions limit regeneration by seeds. However, favourable conditions (e.g. moist conditions in a meadow) partly eliminate the obstacles against seedling emergence. Regeneration by seeds therefore has a major impact on the dynamics and structure of vegetation. In heath vegetation, where bare soils are dry and the moss cover is thick, large seed banks and seed rains do not guarantee effective seedling recruitment. The regeneration process is reduced in the early phases, and plants that reproduce primarily by seeds have a minor role in vegetation. The accumulation of seed banks is effective in these circumstances.

Bioactive glasses and glass-ceramics are a class of third generation biomaterials which elicit a special response on their surface when in contact with biological fluids, leading to strong bonding to living tissues. The purpose of the present study was to develop diopside based alkali-free bioactive glasses in order to achieve good sintering behaviour, high bioactivity, and a dissolution/ degradation rates compatible with the target applications in bone regeneration and tissue engineering. Another aim was to understand the structure-property relationships in the investigated bioactive glasses. In this quest, various glass compositions within the Diopside (CaMgSi2O6) – Fluorapatite (Ca5(PO4)3F) – Tricalcium phosphate (3CaO•P2O5) system have been investigated. All the glasses were prepared by melt-quenching technique and characterized by a wide array of complementary characterization techniques. The glass-ceramics were produced by sintering of glass powders compacts followed by a suitable heat treatment to promote the nucleation and crystallization phenomena. Furthermore, selected parent glass compositions were doped with several functional ions and an attempt to understand their effects on the glass structure, sintering ability and on the in vitro bio-degradation and biomineralization behaviours of the glasses was made. The effects of the same variables on the devitrification (nucleation and crystallization) behaviour of glasses to form bioactive glass-ceramics were also investigated. Some of the glasses exhibited high bio-mineralization rates, expressed by the formation of a surface hydroxyapatite layer within 1–12 h of immersion in a simulated body fluid (SBF) solution. All the glasses showed relatively lower degradation rates in comparison to that of 45S5 Bioglass®. Some of the glasses showed very good in vitro behaviour and the glasses co-doped with zinc and strontium showed an in vitro dose dependent behaviour. The as-designed bioactive glasses and glass–ceramic materials are excellent candidates for applications in bone regeneration and for the fabrication of scaffolds for tissue engineering.
Os vidros e vitrocerâmicos bioactivos fazem parte da chamada terceira geração de biomateriais, i.e., materiais que estimulam uma resposta especial quando em contacto com fluidos biológicos, capaz de conduzir ao estabelecimento de ligações fortes entre a sua superfície e os tecidos vivos. O presente estudo visou o estudo e desenvolvimento de vidros bioactivos à base de diópsido e isentos de metais alcalinos que apresentem um bom comportamento na sinterização, elevados índices de bioactividade, e taxas de dissolução / degradação compatíveis com as almejadas aplicações em regeneração óssea e em engenharia de tecidos. Procurou-se ainda entender as relações entre a estrutura e as propriedades dos vidros bioactivos estudados. De acordo com esta perspectiva, estudaram-se várias composições de vidros bioactivos pertencentes ao sistema Diópsido (CaMgSi2O6) – Fluorapatite (Ca5(PO4)3F) – Fosfato de tricálcico (3CaO•P2O5). Todas as composições vítreas foram preparados por fusão, seguida de fritagem em água fria, e caracterizados através de um conjunto de técnicas complementares de caracterização. Os vitrocerâmicos foram obtidos por sinterização das fritas de vidro moídas e compactadas, seguida de tratamento térmico adequado para promover os fenómenos de nucleação e cristalização. Além disso, algumas composições vítreas seleccionadas foram dopadas com vários iões funcionais e os seus efeitos na estrutura vítrea, na sua propensão para a sinterização, e nos comportamentos in vitro em termos de biodegradação e bio-mineralização foram avaliados. Os efeitos das mesmas variáveis no processo de devitrificação (nucleação e cristalização) dos vidros e formação de materiais vitrocerâmicos foram também investigados. Algumas composições de vítreas apresentaram taxas de bio-mineralização elevadas, expressas através da formação de camadas superficiais de hidroxiapatite após 1-12 h de imersão num fluido fisiológico simulado (SBF). Todas as composições vítreas apresentaram taxas de degradação mais baixas quando comparadas com a do 45S5 Bioglass®. Alguns vidros bioactivos revelaram comportamentos in vitro excelentes, sendo a taxa de biomineralização dos co-dopados com zinco e estrôncio dependente da dose incorporada de dopantes. Os materiais estudados demostraram boa aptidão para aplicações em regeneração óssea e para o fabrico de estruturas de suporte em engenharia de tecidos.

The regenerative heat exchanger is widely used in nuclear power plants and research reactors. It is composed of the regeneration section and the cooling section. The heat transfer mainly occurs at the cooling section, while the regeneration section is designed to reduce the temperature difference between the hot and cold fluids and weaken the damage to the heat exchanger due to the existence of thermal stress. Meanwhile, some heat is also can be recovered through the regeneration section. This paper mainly aims to analyze the thermal characteristics of the regenerative heat exchanger according to its structure properties, and provides some suggestions for regenerative heat exchanger design based on the influence of some key factors on thermal characteristics. The results show that improving the outlet temperature in the regeneration section primary side can both reduce the heat exchange areas of the regeneration section and the cooling section, but this will rise thermal shock and increase the operation safety risk. The baffles arrangement will enhance heat exchange capacity, and the heat exchange area decreases with the baffle gap height increasing. With the heat exchange area margin of the regeneration section improvement, the actual power will gradually reduce. The measures, including increasing secondary water flow or taking a corresponding margin about 52.8%∼59.2% that of the regeneration section for the cooling section heat exchange area, can be taken to overcome the adverse effects of the margin on the regenerative heat exchanger. More heat exchange areas of the regeneration section and the cooling section are required to satisfy the rated power with the fouling thermal resistance of the primary water increasing. Moreover, adopting a lower fouling coefficient favors the generative heat exchanger running under the design power.

The ability to induce limb regeneration in humans is of growing interest in the field of regenerative medicine, particularly due to the increased number of amputees among military veterans. Unfortunately, mammals have limited regenerative capabilities as compared to amphibians, which can re-establish complex structures after traumatic injury. There have been a few clinically documented cases of digit regeneration in children [1], indicating that the potential to regenerate is not completely absent in humans. Mammalian models of epimorphic regeneration is primarily limited to the mouse digit, which has a level-specific response in that amputation at the terminal phalangeal element (P3) results in regeneration, but not at the next more proximal joint (P2) (Figure 1). Recently primary stromal cells were isolated from each of these mouse joints (P3 and P2, respectively) [2], which provides a unique opportunity to utilize in vitro techniques to identify differences in one of the phenotypes prevalent at the amputation plane of a regenerating and non-regenerating region.

Traffic congestion has become the main phenomenon of agglomeration dis-economy in urban. Adjusting spatial structure to improve traffic efficiency and reduce traffic pollution has become an important issue of urban sustainable development. The study adopts the social survey method to test the traffic performance of Harbin polycentric spatial structure. Combine with the colocation hypothesis, the paper analyzes the influencing factors of polycentric commuting distance and commuting time. The results show that the average commuting distance of centers is greater than that in the city, and the proportion of long-distance commuting is higher, but the faster commuting speed in the fringe area subcenters makes average commuting time shorter than that in the city. The importance of commuting costs is insufficient, the employment and residential location resources are extremely unbalanced, and they influence location selection of residence and employment and makes long-distance commuting economically reasonable. The fundamental ways to improve the traffic performance of polycentric spatial structure are to face up to the rationality of long-distance commuting and traffic demand, in urban renewal, adjusting commuting cost and the spatial layout of residential and employment resources, improving the balance between occupation and housing, promoting sustainable urban development.

The regeneration of highly loaded turbine blades causes small variations of their geometrical parameters. To determine the influence of such regeneration-induced variances of turbine blades on the nozzle excitation, an existing air turbine is extended by a newly designed stage. The aerodynamic and the structural dynamic behavior of the new turbine stage are analyzed. The calculated eigenfrequencies are verified by an experimental modal analysis and are found to be in good agreement. Typical geometric variances of overhauled turbine blades are then applied to stator vanes of the newly designed turbine stage. A forced response analysis of these vanes is conducted using a uni-directional fluid-structure interaction approach. The effects of geometric variances on the forced response of the rotor blade are evaluated. It is shown that the vibration amplitudes of the response are significantly higher for some modes due to the additional wake excitation that is introduced by the geometrical variances e.g. 56 times higher for typical MRO-induced variations in stagger-angle.

Lincoln Boyhood National Memorial celebrates the lives of the Lincoln family including the final resting place of Abraham’s mother, Nancy Hanks Lincoln. Lincoln’s childhood in Indiana was a formative time in the life our 16th president. When the Lincoln family arrived in Indiana, the property was covered in the oak-hickory forest type. They cleared land to create their homestead and farm. Later, designers of the memorial felt that it was important to restore woodlands to the site. The woodlands would help visitors visualize the challenges the Lincoln family faced in establishing and maintaining their homestead. Some stands of woodland may have remained, but significant restoration efforts included extensive tree planting. The Heartland Inventory and Monitoring Network began monitoring the woodland in 2011 with repeat visits every four years. These monitoring efforts provide a window into the composition and structure of the wood-lands. We measure both overstory trees and the ground flora within four permanently located plots. At these permanent plots, we record each species, foliar cover estimates of ground flora, diameter at breast height of midstory and overstory trees, and tree regeneration frequency (tree seedlings and saplings). The forest species composition was relatively consistent over the three monitoring events. Climatic conditions measured by the Palmer Drought Severity Index indicated mild to wet conditions over the monitoring record. Canopy closure continued to indicate a forest structure with a closed canopy. Large trees (>45 cm DBH) comprised the greatest amount of tree basal area. Sugar maple was observed to have the greatest basal area and density of the 23 tree species observed. The oaks characteristic of the early woodlands were present, but less dominant. Although one hickory species was present, it was in very low abundance. Of the 17 tree species recorded in the regeneration layer, three species were most abundant through time: sugar maple (Acer saccharum), red bud (Cercis canadensis), and ash (Fraxinus sp.). Ash recruitment seemed to increase over prior years and maple saplings transitioned to larger size classes. Ground flora diversity was similar through time, but alpha and gamma diversity were slightly greater in 2019. Percent cover by plant guild varied through time with native woody plants and forbs having the greatest abundance. Nonnative plants were also an important part of the ground flora composition. Common periwinkle (Vinca minor) and Japanese honeysuckle (Lonicera japonica) continued to be the most abundant nonnative species, but these two species were less abundant in 2019 than 2011. Unvegetated ground cover was high (mean = 95%) and increased by 17% since 2011. Bare ground increased from less than 1% in 2011 to 9% in 2019, but other ground cover elements were similar to prior years. In 2019, we quantified observer error by double sampling two plots within three of the monitoring sites. We found total pseudoturnover to be about 29% (i.e., 29% of the species records differed between observers due to observer error). This 29% pseudoturnover rate was almost 50% greater than our goal of 20% pseudoturnover. The majority of the error was attributed to observers overlooking species. Plot frame relocation error likely contributed as well but we were unable to separate it from overlooking error with our design.
