E-Learning implementation in higher education in response to the covid-19 pandemic: a review

Through the use of technology, various sectors have shifted as a result of the covid-19 pandemic, including the education system. The educational paradigm evolves by leveraging information technology as a vehicle for scientific growth, and online learning has become a part of our life. Face-to-face sessions in traditional classrooms are transformed into live face-to-face sessions in virtual classrooms. The purpose of this study was to examine the implementation carried out by universities in selected research subject countries using the correspondence method of data collection. Correspondence was performed with contacts at several universities and the Ministry of Education (MOE) in each of the countries that became the focus of this research, including Singapore, Hong Kong, Australia, and Canada, in addition to Indonesia. It was then developed as a best practice based on the use of digital learning as an emergency response to the new corona virus pandemic. The findings indicate that Digital Learning, which involves and effectively uses technology, is an alternative option that is being implemented in these countries as part of the Emergency Plan in the education sector in connection with covid-19.
Life history strategies of stream fishes linked to predictors of hydrologic stability

Abstract Life history theory provides a framework to understand environmental change based on species strategies for survival and reproduction under stable, cyclical, or stochastic environmental conditions. We evaluated environmental predictors of fish life history strategies in 20 streams intersecting a national park within the Potomac River basin in eastern North America. We sampled stream sites during 2018–2019 and collected 3801 individuals representing 51 species within 10 taxonomic families. We quantified life history strategies for species from their coordinates in an ordination space defined by trade‐offs in spawning season duration, fecundity, and parental care characteristic of opportunistic, periodic, and equilibrium strategies. Our analysis revealed important environmental predictors: Abundance of opportunistic strategists increased with low‐permeability soils that produce flashy runoff dynamics and decreased with karst terrain (carbonate bedrock) where groundwater inputs stabilize stream flow and temperature. Conversely, abundance of equilibrium strategists increased in karst terrain indicating a response to more stable environmental conditions. Our study indicated that fish community responses to groundwater and runoff processes may be explained by species traits for survival and reproduction. Our findings also suggest the utility of life history theory for understanding ecological responses to destabilized environmental conditions under global climate change.
THE INFLUENCE OF GENDER DIVERSITY ON MARKET VALUE: A COMPARATIVE STUDY BETWEEN EUROPEAN AND LATIN AMERICAN COMPANIES

Debates about gender diversity have addressed the influence of women in organisational environments, and their role in increasing economic and non-economic gains. In this sense, the present study aimed to identify how the perception of a company's value is affected by greater equality between men and women in an organisational environment. Based on secondary data from the social axis of the Refinitiv EIKON database, a quantitative study, using multiple linear regression, was conducted on a sample of 2,195 companies from two blocks of countries: Europe and Latin America. For both country blocks, it was found that greater gender equality on a board of directors had a positive correlation with the market value of the company. Additionally, it was found, but only for Latin America, that a policy of wage equality between the genders, as well as gender equality in terms of management, had a positive correlation with the Tobin's Q indicator. The main innovation in this study is the quantitative approach, as most previous research has relied on qualitative interviews and observations to understand adherence to gender diversity in organisations. The results are robust for the econometrics used and provide support on the potential to broaden the discussion on gender equality in the business environment, identifying and quantifying the influence of women on company values. The study opens space for discussion on the importance of gender quotas in companies. Policy used in Europe.
Initial Development of a Quadcopter Simulation Environment for Auralization

This paper describes a recently created computer simulation of quadcopter flight dynamics for the NASA DELIVER project. Thegoal of thiseffort is to produceasimulation that includesanumber of physical effects that arenot usually found in other dynamics simulations (e.g., those used for flight controller development). These effects will be shown to have a significant impact on the fidelity of auralizations — entirely synthetic time-domain predictions of sound — based on this simulation when compared to a recording. High-fidelity auralizations are an important precursor to human subject tests that seek to understand the impact of vehicle configurationson noise and annoyance.
Differentiation in the Postnatal Thymus Progenitor Localization and T Cell Critical Role for CXCR4 Signaling in

T cell differentiation in the thymus depends on sequential interactions between lymphoid progenitors and stromal cells in discrete regions of the cortex. Here we show that CXCL12/CXCR4 signaling is absolutely required for proper localization of early progenitors into the cortex and thus for successful steady state differentiation. All early progenitors in the thymus express CXCR4, and its ligand (CXCL12) is expressed only by stromal cells in the cortex, where early progenitors are found. Early progenitors migrate in response to CXCL12 in vitro, while thymus-speciﬁc deletion of CXCR4 in vivo results in failed cortical localization and developmental arrest. These ﬁndings indicate a crucial and nonredundant role for CXCR4 in facilitating localization of early lymphoid progenitors to tissue regions of the thymus, where lineage commitment and proliferation are controlled.

A lightweight Anomaly based DDoS flood attack detection for Internet of vehicles

The concept of the Internet of Vehicles (IoV) enhances the VANETs by merging the VANETs with the Internet of things (IoT) thus making intelligent transportation systems a reality. The intelligent transport systems generate greater volumes of critical dynamic real-time data and thus raise a concern in the security of the generated data. The IoV has become a prominent field because of its scalability, reliable internet connection, and dynamic topological structures and due to its compatibility with various devices and sensors. IoV is susceptible to a range of attacks. The IoV consists of various kinds of components which involve various communications with sensors, vehicles, road infrastructure and humans. This paper will focus on UDP based Distributed Denial of Service (DDOS) Flood attacks. Onboard unit (OBU) is a computational device present in the vehicle is a resource-constrained device a lightweight DDoS detection machine learning algorithm is required to detect the DDoS attack performed on the vehicles by a dataset generated using OMNET++ simulator.
Social exclusion and health outcomes among empty nest and non-empty nest older people in China

Many existing studies lack a comprehensive picture of the social exclusion statuses and health outcomes of empty nesters and those empty nesters living alone or with a spouse only. Cross-sectional analysis was conducted on representative national data from the 2014 China Longitudinal Aging Social Survey, focusing on respondents aged 60 and above (N = 7,923). Four dimensions of social exclusion (social relationships, subjective feeling of being excluded, social activities and financial products) and three health outcomes (self-reported health (SRH), activities of daily living (ADLs) and depression), were considered. Results show that ‘empty nest’ older people were more likely to be excluded from social relationships and to experience subjective feelings of being excluded, and were less likely to participate in social activities than non-empty nesters. Empty nesters were significantly less likely to report fair SRH and ADL difficulties than non-empty nesters, but they were more likely to report having depression than non-empty nesters. Among ‘empty nest’ older people, empty nesters who were living alone were associated with higher levels of being excluded from social relationships and to experience subjective feelings of being excluded than those who were living with a spouse only. Future research could focus on the development of age-friendly communities which act as health interventions to address relevant situations of social exclusion and depression among empty nesters.
Receptor 4 Long Terminal Repeat Through Toll-Like Bacterial Lipopolysaccharide Activates HIV

In HIV-infected patients, concurrent infections with bacteria and viruses are known to induce HIV replication as assessed by increases in plasma HIV RNA levels. In the present study, we determined the cell surface receptor and molecular mechanisms of enterobacterial LPS-induced HIV transcription. Human dermal microvessel endothelial cells (HMEC) were transfected with an HIV-long terminal repeat (LTR)-luciferase construct and subsequently stimulated with puriﬁed bacterial LPS. Our studies dem-onstrate that human Toll-like receptor 4 (TLR4) mediates LPS-induced NF- k B and HIV-LTR activation in HMEC through IL-1 signaling molecules, namely myeloid differentiation protein, IL-1R-associated kinase, TNFR-associated factor, and NF- k B-induc-ing kinase. Cotransfection of HMEC with HIV-LTR-luciferase and TLR4 cDNA from LPS-hyporesponsive C3H/HeJ mice ab-rogates LPS-induced HIV transcription as does the use of dominant-negative mutants of the IL-1 signaling molecules. Transfection of HMEC with an HIV-LTR-mutant that lacks the NF- k B binding site or pretreatment of cells with chemical inhibitors of the NF- k B pathway also blocked LPS-induced HIV-LTR transactivation. These data support the conclusion that TLR4 mediates enterobacterial LPS-induced HIV transcription via IL-1 signaling molecules and NF- k B activation plays an important role in HIV-LTR transactivation.

On Optimizing Top-K Metrics for Neural Ranking Models

Top-K metrics such as NDCG@K are frequently used to evaluate ranking performance. The traditional tree-based models such as LambdaMART, which are based on Gradient Boosted Decision Trees (GBDT), are designed to optimize NDCG@K using the LambdaRank losses. Recently, there is a good amount of research interest on neural ranking models for learning-to-rank tasks. These models are fundamentally different from the decision tree models and behave differently with respect to different loss functions. For example, the most popular ranking losses used in neural models are the Softmax loss and the GumbelApproxNDCG loss. These losses do not connect to top-K metrics such as NDCG@K naturally. It remains a question on how to effectively optimize NDCG@K for neural ranking models. In this paper, we follow the LambdaLoss framework and design novel and theoretically sound losses for NDCG@K metrics, while the original LambdaLoss paper can only do so using an unsound heuristic. We study the new losses on the LETOR benchmark datasets and show that the new losses work better than other losses for neural ranking models.
Generation and characterization of shaped femtosecond pulses and their application in spatio-temporal control of speckle pattern

This PhD thesis concerns a range of technological studies and physical applications within the fields of ultrafast science and coherent control. From the technological point of view, we have performed a comprehensive study of space-time coupling within the 'Dazzler' AOPDF pulse shaper using interferometric techniques. For a while such limitations of '4f' zero-dispersion line pulse shapers have been widely documented; our results were the first to demonstrate, quantify and explain a parallel effect in this alternative device. From a control perspective, we have demonstrated exciting results about temporal refocusing of a broadband pulse that has been strongly distorted by a random, multiply scattering medium (i.e. the temporal analogue of the spatial speckle pattern). For this purpose a spatially resolved measurement of the spectral phase of the distorted pulse followed by open-loop feedback to a pulse shaper were implemented: as a result of the linearity of the scattering process, this pre-compensation has led to a spatially localized flat output spectral phase and hence a short pulse. This has already stimulated much interest amongst colleagues for diverse applications such as biological imaging or quantum optics studies.
Future directions for simulation of recreation use

As the case studies in Chapter 4 illustrate, simulation modeling can be a valuable tool for recreation planning and management. Although simulation modeling is already well developed for business applications, its adaptation to recreation management is less developed. Relatively few resources have been devoted to realizing its potential. Further progress is needed in refining the models, and their inputs and outputs. Equally important is work to assess the validity of models as well as to understand the precision of model estimates and the appropriateness of using model outputs for various purposes. Finally, there is substantial potential to link models of recreation behavior to transportation modeling and to models of biophysical impacts to provide more holistic perspectives.Individual papers from this publication
Evaluation of a Novel Remote Displacement Sensor Evaluation of a Novel Remote Displacement Sensor Prototype Using Video and Laser-Based Technology Prototype Using Video and Laser-Based Technology for Civil Infrastructure Applications for Civil Infrastructure Applications

Deflection measurements on structures, especially with regards to long-term monitoring, continues to be a challenge with current sensor technologies. Material degradation and changes in the mechanical properties due to aging (for example, creep and shrinkage in concrete bridges) directly impact the deflections exhibited by a structure. In this article we introduce and discuss the evaluation of a novel laser and video-based displacement sensor prototype to monitor displacements and rotations in structures remotely. The sensor is both inexpensive, using off-the shelf components, but also accurate and practical for situations that do not allow the use of conventional displacement sensors, which require a reference base. In contrast to other image-based approaches such as digital image correlation or Eulerian-based video sensors, our camera-based sensor is located at the measurement location on the structure. The sensor was evaluated using laboratory tests to determine the practicality, accuracy, and sensitivity to lighting conditions. The accuracy of the sensor was found to be approximately +/- 0.9 mm (95% confidence limits) for a 30.5 m (100 ft) measurement distance. Finally, we applied and evaluated the sensor under real-world conditions on a prestressed concrete bridge under different loading conditions as well as on a five-story steel moment-frame building under ambient conditions. Essential for field applications, the results demonstrate the prototype offers an inexpensive yet practical and accurate solution for monitoring displacements and rotations remotely.

Guided wave temperature correction methods in structural health monitoring

In this article, a method for addressing temperature effects using Lamb waves is developed with application to baseline comparison damage detection. The proposed method is based on baseline signal stretch with an improved minimum residual allowing correction over a larger temperature range. The effectiveness of the proposed approach in detecting (artificial) damages is demonstrated experimentally over a large temperature. The method is also shown to accurately detect and localise a crack in an aluminium panel and actual impact damage on a carbon fibre reinforced polymer panel.
Vestibular contribution to path integration deficits in ‘at-genetic-risk’ for Alzheimer’s disease

Path integration changes may precede a clinical presentation of Alzheimer disease by several years. Studies to date have focused on how grid cell changes affect path integration in preclinical AD. However, vestibular input is also critical for intact path integration. Here, we developed a naturalistic vestibular task that requires individuals to manually point an iPad device in the direction of their starting point following rotational movement, without any visual cues. Vestibular features were derived from the sensor data using feature selection. Completing machine learning models illustrate that the vestibular features accurately classified Apolipoprotein E4 carriers and non-carrier controls, mean age 62.7 years, with 65 to 79 percentage accuracy depending on task trial or algorithm. Our results demonstrate the cross-sectional role of the vestibular system in Alzheimer disease risk carriers and may explain individual phenotypic heterogeneity in path integration within this population.
A role for super-spreaders in carrying malaria parasites across the months-long dry season

In malaria endemic regions, transmission of Plasmodium falciparum parasites is often seasonal with very low transmission during the dry season and high transmission in the wet season. Parasites survive the dry season within some individuals who experience prolonged carriage of parasites and are thought to 'seed' infection in the next transmission season. We use a combination of mathematical simulations and data analysis to characterise dry season carriers and their role in the subsequent transmission season. Simulating the life-history of individuals experiencing repeated exposure to infection predicts that dry season carriage is more likely in the oldest, most exposed and most immune individuals. This hypothesis is supported by data from a longitudinal study in Mali that shows that carriers are significantly older, experience a higher biting rate at the beginning of the transmission season and develop clinical malaria later than non-carriers. Further, since the most exposed individuals in a community are most likely to be dry season carriers, we show that this is predicted to enable a more than 2-fold faster spread of parasites into the mosquito population at the start of the subsequent wet season.
Differentiated historical demography and ecological niche forming present distribution and genetic structure in coexisting two salamanders (Amphibia, Urodela, Hynobiidae) in a small island, Japan

Background The climatic oscillations in the Quaternary period considerably shaped the distribution and population genetic structure of organisms. Studies on the historical dynamics of distribution and demography not only reflect the current geographic distribution but also allow us to understand the adaption and genetic differentiation of species. However, the process and factors affecting the present distribution and genetic structure of many taxa are still poorly understood, especially for endemic organisms to small islands. Methods Here, we integrated population genetic and ecological niche modelling approaches to investigate the historical distribution and demographic dynamics of two co-existing salamanders on Tsushima Island, Japan: the true H. tsuensis (Group A), and Hynobius sp. (Group B). We also examined the hypothesis on the equivalency and similarity of niches of these groups by identity and background tests for ecological niche space. Results Our result showed that Group A is considered to have undergone a recent population expansion after the Last Glacial Maximum while it is unlikely to have occurred in Group B. The highest suitability was predicted for Group A in southern Tsushima Island, whereas the northern part of Tsushima Island was the potential distribution of Group B. The results also suggested a restricted range of both salamanders during the Last Interglacial and Last Glacial Maximum, and recent expansion in Mid-Holocene. The genetic landscape-shape interpolation analysis and historical suitable area of ecological niche modelling were consistent, and suggested refugia used during glacial ages in southern part for Group A, and in northern part of Tsushima Island for Group B. Additionally, we found evidence of nonequivalence for the ecological niche of the two groups of the salamanders, although our test could not show either niche divergence or conservatism based on the background tests. The environmental predictors affecting the potential distribution of each group also showed distinctiveness, leading to differences in selecting suitable areas. Finally, the combination of population genetics and ecological modeling has revealed the differential demographic/historical response between coexisting two salamanders on a small island.

Full details of all sequences will be published in a forthcoming report. Below are listed the newly assigned sequences (Table 1) and confirmations of previously reported sequences (Table 2). The accession number of each sequence is given and these can be used to retrieve the sequence files from the EMBL, GenBank or DDBJ data libraries. Although accession numbers have been assigned by the data-libraries and most sequences are already available, there is still the possibility that an author may not yet have allowed the sequence to be released; in such a case you will have to contact the submitting author directly. Additional information pertaining to new sequences is often included in the publications describing these alleles; a listing of recent publications that describe new HLA sequences is given in Table 3. An additional 295 alleles were recently published but have not been included in Table 3 due to space considerations (Turner et al., 2022). In addition, the sequence for the allele A*02:01:08 has been extended to become a new A*02 protein variant. The allele name A*02:01:08 has been abandoned and the sequence renamed A*02:1040. Furthermore, the sequence for the allele C*08:01:08 has been extended and shown to be a new silent variant of the C*08:22 protein group. The allele name C*08:01:08 has been abandoned and the sequence renamed C*08:22:02. All new and confirmatory sequences should now be submitted directly to the WHO Nomenclature Committee for Factors of the HLA System via the IPD-IMGT/HLADatabase using the sequence submission tool provided (Robinson et al., 2020).
