Abstract:
The emergence and development of systems of systems (SoSs) have expanded the complexity and adaptability of systems engineering. Due to the heterogeneity of its constituent systems, designing and analyzing an SoS faces enormous challenges. Therefore, the verification of an SoS is important in its design phase. However, related methods and techniques are still in the preliminary research state, mainly for requirements verification and system verification, and a lack of efforts in design verification for SoSs. Aiming to provide the ability to detect hazardous states at the design phase, we worked on a novel method for automatically generating test cases for model verification in SoSs. Considering the characteristics of SoSs, the method adopts fault injection and model-based system engineering as the foundations to extend the automated generation capability of test cases. This paper proposes an automatic test generation (ATG) method for an SoS based on fault injection and model-based systems engineering (MBSE). It is meant to generate test cases that can be used to check the effectiveness of fault detection or identification in SoSs and for the effective testing of their constituent systems (CSs). This paper discusses scenario generation and ATG in linear temporal logic and designs an algorithm to generate traces as test suites, taking into account the constraints of the models. By establishing a concept alignment example (CAE) as the experimental use case, three test scenarios are generated automatically, showing that the use of the proposed ATG method provides a reasonable hazardous detection capability for verification in SoS design. The main contributions of the paper are (1) the description of the proposed two-phase ATG approach with fault-centric modeling activities and generation-related activities; (2) the explanation of the designed ATG algorithm at both high and low levels; and (3) the discussion of the experiment in an emergency response CAE with three generated test scenarios.

Abstract:
Methamphetamine (METH) is abused worldwide, and it represents a threat for public health. METH exposure induces a variety of detrimental effects. In fact, METH produces a number of oxidative species, which lead to lipid peroxidation, protein misfolding, and nuclear damage. Cell clearing pathways such as ubiquitin-proteasome (UP) and autophagy (ATG) are involved in METH-induced oxidative damage. Although these pathways were traditionally considered to operate as separate metabolic systems, recent studies demonstrate their interconnection at the functional and biochemical level. Very recently, the convergence between UP and ATG was evidenced within a single organelle named autophagoproteasome (APP), which is suppressed by mTOR activation. In the present research study, the occurrence of APP during METH toxicity was analyzed. In fact, coimmunoprecipitation indicates a binding between LC3 and P20S particles, which also recruit p62 and alpha-synuclein. The amount of METH-induced toxicity correlates with APP levels. Specific markers for ATG and UP, such as LC3 and P20S in the cytosol, and within METH-induced vacuoles, were measured at different doses and time intervals following METH administration either alone or combined with mTOR modulators. Western blotting, coimmunoprecipitation, light microscopy, confocal microscopy, plain transmission electron microscopy, and immunogold staining were used to document the effects of mTOR modulation on METH toxicity and the merging of UP with ATG markers within APPs. METH-induced cell death is prevented by mTOR inhibition, while it is worsened by mTOR activation, which correlates with the amount of autophagoproteasomes. The present data, which apply to METH toxicity, are also relevant to provide a novel insight into cell clearing pathways to counteract several kinds of oxidative damage.

Abstract:
Autophagy is an evolutionarily-conserved, intracellular degradation system for which two ubiquitin-like modifiers, Atg8 and Atg12, play essential roles. After processed by Atg4, the exposed C-terminal glycine of Atg8 is activated by Atg7 (E1) and is then transferred to Atg3 (E2), and is finally conjugated with a phospholipid, phosphatidylethanolamine (PE) through an amide bond. Whereas, Atg12 is activated by the same E1, Atg7, without processing, and is then transferred to Atg10 (E2), and is finally conjugated with Atg5 through an isopeptide bond. Atg12-Atg5 conjugates, together with Atg16, function as an E3-like enzyme to facilitate the conjugation reaction between Atg8 and PE. During autophagy, Atg8-PE conjugates play a critical role in selective cargo recognition in addition to autophagosome formation. We determined the structures of all these Atg proteins and their complexes mainly by X-ray crystallography, and performed structure-based biochemical analyses on them [1,2]. These studies established the molecular mechanisms of Atg8 and Atg12 modification reactions that have many unique features compared with canonical ubiquitin-like systems. Furthermore, we found a conserved motif named the Atg8-family interacting motif (AIM), through which Atg8 recognizes specific cargoes and selectively incorporates them into autophagosomes for degradation [3].

Abstract:
With the continuous development of the Internet of things (IoT) technology, the air-to-ground (ATG) system has attracted more and more attention. The system will effectively increase communication coverage and improve communication quality. The ATG system uses frequency reuse technology in the ground layer to further utilize frequency resources. This paper focuses mostly on the cochannel interference between the 5G BS and the ATG airborne CPE terminal in the 3.5 GHz range. The ATG airborne CPE terminal has to be further isolated from 5G BS in order to prevent interference. We must manage the transmitting power of the ATG airborne CPE terminal in order to comply with the additional isolation criteria. The RSRP value of 5G BS determines the transmit power of the ATG airborne CPE terminal. We creatively suggested a machine learning (ML) approach based on multihead attention to anticipate the RSRP of 5G BS because it is highly challenging for the ATG aerial CPE terminal to monitor the RSRP of 5G BS in real time. By comparing the suggested ML-based approach with the actual measured values, its efficacy is confirmed.

Abstract:
Fuel station monitoring systems traditionally rely on monolithic software architectures that tie together multiple functionalitiesranging from dispenser data collection to Automated Tank Gauge (ATG). As the need for agile, scalable, and cost-effective solutions grows, leveraging a serverless, microservices-based architecture offers many benefits. This paper presents the design and implementation of a microservices architecture using AWS Lambda for fuel station monitoring, integrating continuous data from pumps, ATG sensors, and real-time analytics. Building on insights from previous research on real-time reconciliation, visualization, and data streaming, we show how AWS Lambda functionsalong with other AWS services such as Amazon API Gateway, AWS IoT Core, and Amazon Kinesisform a resilient, fault-tolerant, and cost-effective platform. Our solution allows for independent service scaling, quick deployments, and secure data handling, thereby addressing the limitations of monolithic systems in fuel station operations.

Abstract:
Neste estudo, avaliamos e caracterizamos o efeito de Ang II em leito venular mesentérico (LVM) e anéis de veia porta (AVP) de wistar e SHR. A reatividade vascular para Ang II foi estudada na presença e ausência de diferentes antagonistas para elucidar os mecanismos envolvidos na venoconstrição induzida por Ang II. Nossos resultados sugerem que a Ang II induz venoconstrição através da ativação de receptores AT1 e AT2 em Wistar e receptor AT1 em SHR. Essa venoconstrição parece ser contrabalanceada pelo receptor B2 em ambas as espécies. NO contribue para este efeito em wistar e metabólitos da COX em SHR. Há redução da venoconstrição induzida por Ang II em AVP de SHR que pode estar relacionado a redução da expressão protéica de receptores AT2. Esses resultados indicam diferentes mecanismos de regulação do tônus venoso de ratos wistar e SHR em resposta a Ang II que podem ter relevância no controle do retorno venoso e débito cardíaco.<br>In this study we have evaluated and characterized the effect of Ang II in the isolated perfused mesenteric venular bed (MVB) and portal vein rings (PVR) of SHR and wistar rats. Vascular reactivity to Ang II was studied in the absence and presence of different antagonists to elucidate the mechanisms involved in Ang II-induced venoconstriction. Our results suggest that Ang II induces venoconstriction by activation of AT1 and AT2 receptors in wistar and AT1 receptor in SHR. These venoconstriction seems to be counterbalanced by B2 receptor in both species. NO might contribute to this effect in wistar and COX metabolites in SHR. There is a decrease in Ang II induced venoconstriction in PVR of SHR that might be related to the decrease of protein expression of AT2 receptor. These results indicate different mechanisms of regulation of venous tonus of the SHR and wistar rats induced by Ang II that can be relevant in the control of the venous return and cardiac output.

Abstract:
O Sistema renina-angiotensina (SRA) tem sido relatado como um importante modulador de processos inflamatórios e imunológicos, incluindo a doença periodontal (DP). Estudos sugerem neste sistema um eixo alternativo (ECA-2 /ANG(1-7) /MAS) que atuaria como um contra-regulador de efeitos mediados pelo clássico eixo (ECA /ANGII /AT1). Sabe-se que bactérias periodontopatogênicas, como a Porphyromonas gingivalis (Pg), possuem componentes bioativos de membrana (ex. lipopolissacarídeos-LPS) capazes de induzir uma forte resposta imune no hospedeiro devido à liberação de citocinas nas células, entre elas Interleucina (IL)- 1&#x3B2;. Neste contexto, fibroblastos são as células mais abundantes nos tecidos periodontais e possuem em sua superfície celular receptores necessários para o reconhecimento da invasão bacteriana, ativando cascatas intracelulares, que levam à produção de citocinas. O objetivo deste estudo foi verificar se os eixos ECA/ ANGII/ AT1 e ECA-2/ ANG(1-7)/ MAS contribuem para a produção e/ ou regulação de citocinas inflamatórias (CI) por fibroblastos de gengiva humana (HGF) e ligamento periodontal humano (HPLF) estimulados por IL-1&#x3B2;. Após o pré-tratamento com Losartan e Ang (1-7) ou silenciamento mediado por RNA de interferência (RNAi) de AT1, HGF e HPLF foram estimulados por IL-1&#x3B2; por 3 horas (RNAm) ou 24 horas (proteína). Expressão de RNAm para AT1, MAS, ECA, ECA-2, IL-1&#x3B2;, TNF-&#x3B1;, IL-6, IL-8, IL-10, TGF-&#x3B2;, CXCL12, RANK-L e OPG foram avaliados por RT-qPCR e das proteínas IL-6, IL-8, ECA e ECA-2 por ELISA. Foi realizado também Western Blot para detecção de AT1 e ECA nos extratos celulares e dosagem de nitrito no sobrenadante das culturas. Ambos os subtipos de fibroblastos mostraram aumento da expressão de RNAm para AT1, IL-1&#x3B2;, IL-6, IL-8, TNF-&#x3B1; e OPG, quando estimulados por IL-1&#x3B2;. No entanto, apenas em HPLF foi observado aumento para MAS, ECA e TGF-&#x3B2;. Losartan e Ang (1-7) não modularam o transcrito, a secreção de CI e nem a produção de nitrito no sobrenadante das culturas, tanto em HGF como em HPLF. O silenciamento do receptor AT1 reduziu a secreção de IL-6 e IL-8 induzida por IL-1&#x3B2; em cultura de HGF e HPLF e aumentou a expressão gênica de OPG somente em HGF. Estes resultados sugerem que o silenciamento de AT1, mas não o bloqueio farmacológico deste receptor pelo antagonista Losartan, em HGF e HPLF, pode controlar a produção de IL-6 e IL-8, que por sua vez contribuem para a patogênese periodontal.<br>The renin-angiotensin system (RAS) has been reported as an important modulator of inflammatory and immune responses, including periodontal disease (PD). Studies suggest an alternative axis as part of this system (ACE-2 / ANG (1-7) / MAS) that would act as counter-regulatory to the classical axis (ECA / ANGII / AT1). It is known that periodontal bacteria such as Porphyromonas gingivalis (Pg) have bioactive components in their membrane (such as lipopolysaccharide-LPS) capable of inducing a strong immune response in the host due to the release of cytokines in cells, including interleukin (IL) - 1&#x3B2;. In this regard, fibroblasts are the most abundant cells in periodontal tissues and receptors needed for the recognition of bacterial invasion by activating intracellular cascades that lead to cytokine production. The aim of this study was to determine whether the axes ACE / ANGII / AT1 and ACE-2 / ANG (1-7) / MAS contribute to the production and / or regulation of inflammatory cytokines (IC) by fibroblasts of human gingiva (HGF) and human periodontal ligament (HPLF) stimulated IL-1&#x3B2;. After pre-treatment with Losartan, Ang (1-7) or silencing mediated by RNA interference (RNAi) of AT1, HGF and HPLF were stimulated by IL-1&#x3B2; for 3 hours (RNAm) or 24 hours (protein). Expression mRNA for AT1, MAS, ACE, ACE-2, IL-1&#x3B2;, TNF-&#x3B1;, IL-6, IL-8, IL-10, TGF-&#x3B2;, CXCL12, RANK-L and OPG was assessed by RT- qPCR and proteins IL-6, IL-8, ACE and ACE-2 by ELISA. Western Blot for the detection of AT1 and ECA and dosage of nitrite was also performed. Experiments stimulated by IL-1&#x3B2; showed a positive control for gene expression AT1, IL-1&#x3B2;, IL-6, IL-8, TNF-&#x3B1; and OPG in HGF and HPLF and MAS, ACE and TGF-&#x3B2; only HPLF. Losartan and Ang (1-7) did not modulate the transcription and secretion of IC and no nitrite production in the culture supernatant of HGF and HPLF. The silencing AT1 reduced IL-6 secretion and IL-8 induced by IL- &#x3B2; in cultured HGF and HPLF and increased OPG gene expression only HGF. These results suggest that silencing AT1, but not pharmacological blockade of this receptor by Losartan in HPLF and HGF, can control the production of IL-6 and IL-8, which in turn contribute to the pathogenesis of periodontal disease.

Abstract:
A hiperatividade do Sistema Renina Angiotensina (SRA) está intimamente relacionada a hipertensão. Avaliamos os efeitos sequênciais do treinamento aeróbio e sedentarismo sobre a pressão arterial média (PAM), frequência cardíaca (FC) e o SRA vascular em ratos SHR e WKY. Ao início dos protocolos SHR vs WKY apresentaram elevada PAM e FC. Ang II era superior em SHR vs WKY nas artérias renais, femorais e carótidas. O conteúdo de Ang (1-7) em SHR vs WKY era inferior nas renais, superior nas femorais e nas carótidas. O treinamento promoveu já na primeira semana redução de Ang II nas renais e aorta de SHR e WKY, femorais e carótidas de SHR; redução de Ang (1-7) nas renais, carótidas e aorta de SHR e WKY, e femoral de SHR. Redução da PAM foi observada apenas nos SHR a partir da 8ª semana de treinamento, por outro lado SHR e WKY apresentaram bradicardia de repouso na 2ª e 8ª semanas respectivamente. Em linhas gerais o treinamento promoveu imediata, progressiva e mantida redução da Ang II e Ang (1-7) vascular, favorecendo a redução da PAM nos SHR e da FC em ambos os grupos.<br>Hyperactivity of the Renin Angiotensin System (RAS) is closely related to hypertension. We evaluated the effects of aerobic training and sedentarism on blood pressure (MBP), heart rate (HR) and vascular RAS in SHR and WKY. At the beginning of protocols SHR vs. WKY showed high MAP and HR. Ang II was higher in SHR vs. WKY renal, femoral and carotid arteries. The contents of Ang (1-7) in SHR vs. WKY was lower in renal than in the femoral and carotid arteries. The training caused a reduction in the first week of Ang II in renal artery and aorta of SHR and WKY, femoral and carotid arteries SHR. And reduction of Ang (1-7) in renal artery, carotid and aorta of SHR and WKY, with reduction only in SHR femoral artery. Reduction of MAP was observed only in SHR from 8 weeks of training, on the other hand SHR and WKY had resting bradycardia at 2 and 8 weeks respectively. In general the training caused immediate, sustained and progressive reduction of Ang II and Ang (1-7) vascular, favoring the reduction in MAP in SHR.

Abstract:
The United Kingdom’s Civil Aviation Authority published the national aviation forecast in 2008. The forecast predicts that domestic traffic will increase by 3.5% per year, and that international traffic will grow, on average, by 4.5% during 2010-2020. Based on this prediction, the traffic density will increase dramatically in the future, and airspace will be more and more congested. Usually, there are two potential solutions to deal with this situation: improving the ability of air traffic flow management is one solution; reducing the separation minimum of aircraft is another solution. However, this thesis focuses on the second solution, based on constraints of communication, navigation and surveillance systems (CNS). Cont?d.

Abstract:
Non-controlled airports are literally that - uncontrolled. Safe separation is achieved by pilot vigilance. The consensus of reports on incidences at noncontrolled airports generally conclude that pilots cannot rely entirely on vision to avoid collision and attempts should be made to obtain all available traffic information to enable a directed traffic search. Ideally, a system is required which has the ability to provide advice to all parties to ensure separation minima is maintained. Provision of a such a system would remove a measure of pressure from the pilot to allow that person to devote their attention to their prime responsibility of flying the aircraft. To this end, research on use of intelligent remote advisory systems for non-controlled airports was undertaken with emphasis on those systems which could minimize human resources and associated recurring costs, to provide a measure of repeatability and to provide an acceptable level of safety. A rule based system was developed and evaluated. The evaluation showed that use of a rule based system as the basis of an intelligent remote air traffic control system for non-controlled airports is a viable proposition. In test scenarios, collision hazards were identified and evasion tactics generated. For a full operational system, the application of the rules and definition of the aircraft circuit area may need refining; however, the results are certainly encouraging.

Abstract:
Abstract Alternating timed automata (ATA) are an extension of timed automata, that are closed under complementation and hence amenable to logic-to-automata translations. Several timed logics, including Metric Temporal Logic (MTL), can be converted to equivalent 1-clock ATAs (1-ATAs). Satisfiability of an MTL formula reduces to checking emptiness of a 1-ATA. Furthermore, algorithms for 1-ATA emptiness can be adapted for model-checking timed automata models against 1-ATA specifications. However, existing emptiness algorithms for 1-ATA proceed by an extended region construction, and are not suitable for implementations. In this work, we initiate the study of zone-based methods for 1-ATAs. The challenge here, as opposed to timed automata, is the fact that the zone graph may generate an unbounded number of variables. We first introduce a deactivation operation to the 1-ATA syntax that allows for an explicit deactivation of the clock in transitions. Using the deactivation operation, we improve the existing MTL-to-1-ATA conversion and present a fragment of MTL for which the equivalent 1-ATA generate a bounded number of variables. Secondly, we develop the idea of zones for 1-ATA and present an emptiness algorithm which explores a corresponding zone graph. For termination, a special entailment check between zones is necessary. Our main technical contributions are: (1) an algorithm for the entailment check using simple zone operations and (2) an $$\textsf{NP}$$ -hardness for the entailment check in the general case. Finally, for 1-ATA which generate a bounded number of variables, we present a modified entailment check with quadratic complexity.

Abstract:
Abstract The Adenosine Triphosphate (ATP) technology can be used as a measurement of the total living biomass. However, care must be exercised in its application and its interpretation. The use of this technique on samples from cooling water systems clearly indicate that there are three distinct pools of ATP, classified as bacterial ATP, free ATP and total ATP, the latter being the sum of the free ATP and bacterial ATP. The mode of action of certain biocidal agents is by disruption of cell membranes, a process which does not decrease the pool of total ATP, but does move ATP from the bacterial ATP pool to the free ATP pool. As a consequence, it is important that for a realistic interpretation to be made, it is necessary to know which biocidal agents are being used and to fully understand their mode of action.

Full text
Abstract:
Past and current Navy maintenance philosophy in military systems is to perform maintenance at scheduled intervals based on manufacturer maintenance recommendations. For example, if a manufacturer recommends that lube oil filters require replacement every 300 operating hours, maintenance personnel replaced oil filters regardless of condition. The Rolls Royce Naval Marine INC (RRNMI) designed, RR4500 Auxiliary Turbine Generator (ATG) program has designed advanced system monitoring capable of indicating out of specified conditions warning shipboard personnel to take maintenance action. Using a variety of sensors and state-of-the-art micro-processing, the RR4500 ATG utilizes a combination of audible and visual alarms alerting operators of out of condition parameters. The warning system allows maintenance personnel to investigate potential system problems before more serious damage occurs. However, maintenance personnel rely on alarms rather than performance trending to commence maintenance actions which requires an unscheduled system shutdown to correct the problem. Condition Based and Predictive Maintenance utilizes trending of data, already captured by the Full Authority Digital Control (FADC), to predict a potential failure prior to the onset of an alarm or system shutdown. This maintenance philosophy is called Condition Based Maintenance (CBM). Maintenance actions are based on the condition of the hardware or system rather a scheduled maintenance plan. The proposed application of CBM and Predictive Maintenance for the RR4500 ATG will be presented.

Full text
Abstract:
An on demand oil system, based on electrically driven lube and scavenge pumps, for use in gas turbine engines has been developed. The need to optimize gas turbine engine performance, coupled with ‘electrification’ of aircraft systems, as on the Lockheed F35 and Boeing 787 in order to maximize efficiency and flexibility, created an opportunity to develop a ‘smart’ electrically driven lubrication system for gas turbine engines. Spytek’s electric oil system, developed for use on its 400lbt ATG-2 engine platform, ascertains the operating condition of the gas turbine engine, including speed, pressure, bearing temperatures and determines the amount of lubrication required for each bearing zone. The system has the benefit of better thermal control of engine bearings, lower system weight and power use, with flexibility in the placement of the system on the engine/airframe combination. The system has been successfully demonstrated on the Spytek Aerospace ATG-2/J304 gas turbine engine series. Major areas addressed in the development of the system were the selection of reliable, gas turbine engine compatible feed and scavenge pumps, control systems sensoring and feedback, variable feed of oil to the individual sump wells, as well as systems durability and operating parameters. Various gas turbine engine platforms can require altered oil system duty cycles, including pre-oiling or post run down-oiling, high flow oil conditions, features not readily available in traditional mechanical systems but easily implemented using the Spytek on-demand oil system. In the project effort, evaluation of the existing prototype system was used as a system design baseline. Data on pump wear, filter performance and oil supply degradation was available and used in refining the oil system design. The ATG-2 system was modified to take advantage of a full proportional integral derivative controlled oil system with system demonstrations made on a gas turbine engine, demonstrating oil supply on demand capability and full bearing thermal management system control.

Abstract:
Rail is used as a form of transportation by millions of people each day. Many of these rail transit systems utilize automatic operation. Automatic operation of rail transit vehicles is provided by an Automatic Train Control (ATC) system, which is typically partitioned into three subsystems: Automatic Train Protection (ATP), Automatic Train Operation (ATO), and Automatic Train Supervision (ATS). This paper discusses the results of a post-incident safety analysis performed on an ATP system. A Fault Tree Analysis (FTA) was performed on a vehicle ATP subsystem following several incidents involving a compromise in system safety. The results of the FTA showed that the vehicle ATP subsystem did not meet the “fail safe” design criteria. This paper uses the results of the FTA to identify possible safety improvements.

Abstract:
The highest level of automation may be achieved with traditional fixed block systems with numerous benefits. Diagnostic Data can be collected from wayside infrastructure and stored in a central depository. Diagnostics from the vehicle may also be collected, not typically in a dynamic fashion, and stored in a centralized depository. This data is not easily integrated or sequenced between the onboard and wayside. External systems are added to collect all data. This centralized system composes a Maintenance and Diagnostic Center. In addition, with CBTC systems, communication between the wayside and the vehicle include ATP information, Movement Authority, Speed Restrictions from the wayside to the vehicle and reports of train location, speed, travel direction and vehicles status. With ATO, data is also transferred between the train and wayside. Much of the vehicle reported ATO data includes vehicle and on-board controller alarms and events. This train and wayside communicated data is collected and stored in the MDC with the added benefit of being integrated between the on-board and wayside. This integrated data allows data mining to be performed to evaluate many operating aspects of the system. This presentation identifies some of the types of data collected and the analysis that may be performed on the data to identify improvements that are to be integrated in system operation, detect system components that are degrading to a point of failure to help schedule maintenance before failure and provide the capability to review events post mortem to identify the root cause of failures that occur in the system.

Full text
Abstract:
Recent literature on the political economy of education highlights the role of political settlements, political commitments, and features of public governance in shaping education systems’ development and performance around learning. Vietnam’s experiences provide fertile ground for the critique and further development of this literature including, especially, its efforts to understand how features of accountability relations shape education systems’ performance across time and place. Globally, Vietnam is a contemporary outlier in education, having achieved rapid gains in enrolment and strong learning outcomes at relatively low levels of income. This paper proposes that beyond such felicitous conditions as economic growth and social historical and cultural elements that valorize education, Vietnam’s distinctive combination of Leninist political commitments to education and high levels of societal engagement in the education system often works to enhance accountability within the system in ways that contribute to the system’s coherence around learning; reflecting the sense and reality that Vietnam is a country in which education is a first national priority. Importantly, these alleged elements exist alongside other features that significantly undermine the system’s coherence and performance around learning. These include, among others, the system’s incoherent patterns of decentralization, the commercialization and commodification of schooling and learning, and corresponding patterns of systemic inequality. Taken together, these features of education in Vietnam underscore how the coherence of accountability relations that shape learning outcomes are contingent on the manner in which national and local systems are embedded within their broader social environments while also raising intriguing ideas for efforts to understand the conditions under which education systems’ performance with respect to learning can be promoted, supported, and sustained.

Full text
Abstract:
The disappointing performance of education systems in developing countries in improving learning outcomes has spurred research aimed at establishing what features of education systems determine their effectiveness or failure in improving learning outcomes. There has been special interest in the challenge of making education systems more coherent for learning, i.e., developing systems in which accountability relations among stakeholders across key elements of education policy design support and sustain strong learning outcomes. In the emergent literature on the political economy of education, a great deal of attention has been directed at Vietnam, a lower-middle income country whose results on assessments of learning have been vastly higher than all other countries in its income group and have even surpassed learning assessment results of many OECD countries. This has led to a raft of research papers asking, “how did Vietnam do it?” Addressing this question, this paper explores Vietnam’s education system’s coherence for learning through an analysis of accountability relations across three key elements of education policy design — delegation, finance, and information. Our aim is to ascertain how features of these policy elements’ practice may variously support or undermine the Communist Party of Vietnam’s objective of promoting quality education and improved learning outcomes for all. The potentially surprising answer to the “how coherent” question posed in the title is, not really that much. Analysis finds that Vietnam’s education system remains weakly "coherent around learning" and is best understood as a “formal process compliant” system that, despite its many strengths, is nonetheless underperforming relative to its potential. The implications of this for efforts to enhance the system’s performance around learning are explored in brief.

Abstract:
This report examines five early childhood coaching systems—two state systems (Alabama and Washington) and three California county systems (El Dorado, Fresno, and San Diego)—that have developed systemic coaching approaches. We studied these coaching systems to understand the different ways that comprehensive coaching systems can be implemented at scale, the types of coaching approaches used, and the supports offered. Although there is no singular strategy to scale effective coaching, this research provides insights for policymakers and program administrators seeking to incorporate coaching into their efforts to improve the quality of early childhood education.

León, Carlos, and Kimmo Soramäki. The Next Generation RTGS: Liquidity Saving Mechanisms as an Overlay Service. FNA, 2024. http://dx.doi.org/10.69701/cfcz133.

Full text
Abstract:
Between 1985 and 2006, a total of 96 central banks implemented Real-time Gross Settlement (RTGS) systems. The adoption of this technology was driven to reduce risks inherent in the then-predominant Deferred Net Settlement (DNS) systems. However, because RTGS systems consume large amounts of liquidity when each payment is settled individually, many RTGS systems (e.g., CHAPS and Target2) implemented Liquidity-Saving Mechanisms (LSMs) of varying complexity, with most deploying variations of the algorithm presented by Morten Bech and Kimmo Soramäki (the co-author) in 2001. Many of these systems are now at the end of their investment cycle, and a conversation has begun on what technology the next generation of RTGS systems should employ. In this paper, we argue that the concept of an LSM Overlay Service that separates the functioning of the core central bank ledger, the RTGS system, and the LSMs has several benefits over existing system architectures. An LSM Overlay Service will rearrange how interbank payments are processed. This service overlays the RTGS system with LSMs that resequence (and in case of PvP or DvP synchronise) payment orders before they reach a "thin" RTGS system with very basic operational processing functionality. Introducing the LSM Overlay Service unlocks many benefits for financial institutions while preserving the central bank's mandate to guarantee the safe and efficient functioning of the payment system with a more resilient service at a lower cost.

Full text
Abstract:
Tide gauges can capture sea level variability on multiple timescales, from high frequency events like waves, tides and tsunamis, to seasonal and interannual changes and the longer-term trends associated with Climate Change. However, financial constraints dictate that they are often maintained to lower standards than the stringent accuracy requirements demanded by the IOC-UNESCO’s Global Sea Level Observing System (GLOSS) for monitoring sea level rise. In addition, a sparsity of Global Navigation Satellite System (GNSS) receivers at the coast means that there are large uncertainties in rates of land motion at tide gauges, which also hampers the estimation of long-term sea level trends. Task 5.1.1 has devised prototype low maintenance tide gauge systems, powered by renewable energy and which monitor both land motion and sea level using novel techniques such as ground-based GNSS Interferometric Reflectometry (GNSS-IR). These systems eliminate the need for costly ongoing levelling exercises and also incorporate customisations to local monitoring needs, such as sensors for lightning detection and wave height. Despite a number of unforeseen setbacks, these prototype systems are now operating at 2 locations in the Mediterranean Sea and a third system is in transit to Colombia for installation by local stakeholders who have been trained in the installation methodology by the WP5 team. It is hoped that there is potential to advance these technological solutions as a global standard, via the GLOSS community. (EuroSea Deliverable, D5.9)

Abstract:
The modern understanding of the state as a complex social system allows us to assert that its resilience is based on ensuring systemic homeostasis as a stabilizing dynamic mechanism for resolving contradictions arising in society associated with the threat of losing control over the processes of public administration and legal regulation. Public administration is a kind of social management that ensures the organization of social relations and processes, giving the social system the proper coordination of actions, the necessary orderliness, sustainability and stability. The problem of state resilience is directly related to the resilience of state (public) administration requires a «breakthrough in traditional approaches» and recognition of «the state administration system as an organic system, the constituent parts and elements of which are diverse and capable of continuous self-development». Within the framework of the «organizational point of view» on the control methodology, there are important patterns and features that determine the viability and resilience of public administration and regulation processes in the state and society. These include: W. Ashby's cybernetic law of required diversity: for effective control, the degree of diversity of the governing body must be no less than the degree of diversity of the controlled object; E. Sedov’s law of hierarchical compensations: in complex, hierarchically organized and networked systems, the growth of diversity at the top level in the structure of the system is ensured by a certain limitation of diversity at its lower levels; St. Beer’s principle of invariance of the structure of viable social systems. The study was supported by the RFBR and EISI within the framework of the scientific project No. 21-011-31155.

Full text
Abstract:
As pipeline coating and associated cathodic protection (CP) systems age, areas along the pipeline inevitably develop that fall below a prescribed CP criterion. In efforts to meet an adequate CP criterion, engineers often resort to supplementing their existing CP system with magnesium anodes at these "low" potential areas resulting in a "hybrid" cathodic protection system consisting of an impressed current CP system (ICCP) supplemented with magnesium (Mg) anodes. This often achieves the desired result i.e. the potential measured over the pipe becomes more negative. However, there remain several unanswered questions concerning the real benefits to the polarization level of the pipe and the overall effect on the impressed current cathodic protection system. The primary objective of this PRCI project was to develop a better understanding of the relationship between ICCP systems and Mg anodes installed as hot-spot protection. This understanding will assist CP engineers in the design and operation of effective, economic CP systems.

Abstract:
The coronavirus disease 2019 (COVID-19) crisis has caused unprecedented levels of disruption to education systems worldwide. Across the Asia region, it is estimated that around 760 million children were impacted by school closures at the height of the pandemic. Government response strategies have varied across the region, with some countries imposing prolonged school lockdowns while others have had short, repeated closure periods. As countries begin to reopen schools and continue to prepare for subsequent waves of COVID-19 infection, there is a need to develop the greater capability of education systems to safeguard learning and address persistent barriers to learning equality by harnessing the opportunities for systemic change. However, school-based practices and responses that have been effective in supporting the continuity of learning during the COVID-19 pandemic have yet to be well examined, particularly in Asia. While the system and school structures are a crucial component of educational quality, understanding what happens in a school setting can offer meaningful insights into overcoming barriers to educational quality as education systems recover and rebuild from the pandemic. This report presents the findings of research undertaken in the Kyrgyz Republic, Central Asia. It forms part of a broader study that aims to explore the system and school-level practices that have supported learning continuity in Asia during the pandemic. The study will focus on the practices of policymakers that have supported teaching and learning and consider ways in which school leaders, teachers, and parents have worked to support children during periods of disruption. Rather than comparing the responses of countries in Asia, this study will highlight innovations in the system and school policies and programs in the Kyrgyz Republic and make recommendations based on insights from the Kyrgyz Republic’s education system. The study will focus on the system and school participants that support students in the Kyrgyz Republic but will not include students themselves.
