Black-body luminance and magnitudes per square arcsecond in the Johnson-Cousins BVR photometric bands
Authors: Bara Salvador
Published: October 2019

A relevant amount of light pollution studies deal with the unwanted visual effects of artificial light at night, including the anthropogenic luminance of the sky that hinders the observation of the celestial bodies which are a main target of ground-based astrophysical research, and a key asset of the intangible heritage of humankind. Most quantitative measurements and numerical models, however, evaluate the anthropogenic sky radiance in any of the standard Johnson-Cousins UBVRI photometric bands, generally in the V one. Since the Johnson-Cousins V band is not identical with the visual CIE V() used to assess luminance, the conversion between these two photometric systems turns out to be spectrum-dependent. Given its interest for practical applications, in this Letter we provide the framework to perform this conversion and the transformation constants for black-body spectra of different absolute temperatures.

Imágenes en fuga*. Entropía, incertidumbre y gravitación en el análisis estético de la producción de sentido visual (Reflexiones sobre un texto de Robert Smithson).
Authors: Maldonado Gómez José
Published: October 2019

En la revista de arte Artforum de junio de 1966 Robert Smithson (New Jersey, 1938) escribe un inquietante y radical ensayo que llevaba por título Entropía y los nuevos monumentos. El ensayo analiza el trabajo de una serie de artistas y las concepciones implicadas en la producción de los creadores citados en el mismo; también de cómo se inscriben en un determinado contexto espaciotemporal tales producciones. Smithson desarrolla una serie de conceptos, que han sido tratados tanto por él como por otros autores y artistas, de una manera intensa e interesante en términos conceptuales, poéticos y plásticos, pero a la vez con un rigor científico calibrado de una manera exótica, extraña y difusa, pero muy sugerente e inspiradora. Entre los conceptos empleados se encuentra el de entropía, que es a la vez sencillo y enigmático, pero también complejo y esencial. El concepto de entropía es relevante en términos semióticos para comprender las interacciones inevitables entre diferentes campos de conocimiento y la estructuración tanto del lenguaje como de la acción comunicativa y su deriva. En el presente artículo se analizan algunos de los conceptos y definiciones empleados por Smithson y otros autores, artistas o no, y la relevancia que estos tienen para el trabajo con imágenes, la producción de sentido a través de estas, y el constante retroajuste (retrolectura, etc…) que debemos aplicar para evitar, o al menos ralentizar, la desaparición (grado de visibilidad) o fuga de las imágenes constituidas o conformadas, independientemente de su naturaleza. Es decir, se intenta investigar la tendencia, a través de la generación y traslación de matemas físico matemáticos, entre otras herramientas, de las pretendidas imágenes a la fuga tanto de su potencial sentido lingüístico como plástica, visualmente (su desaparición, alejamiento o momento de equilibrio), y los factores que hacen de las imágenes y su producción, emisión y recepción, objetos de conocimiento independientes y liberados con un alto potencial metafórico, y por consiguiente, enlazados con conceptos y dinámicas tales como entropía, incertidumbre y gravitación.
Volcanología y geocronología de extensos flujos basálticos neógeno cuaternarios del sureste de Payenia, centro-oeste de Argentina

Published: October 2019

The basaltic lava flows located in the southeast of Payenia Volcanic Province, Argentina, show lengths between 40 and 181 km. These flows have transversal sections characterized by external vesicular crusts that surround a massive core hosting vesiculated structures. These characteristics defined them as P-type pahoehoe flows. Based on their surface topography, 2 types of flows were determined: sheet flows and hummocky flows. The first were emplaced through inflation and lateral coalescence of lobes in the front of the flow, giving rise to flat roofs and large lateral width. The second ones exhibit a microrelief given by local inflation structures (e.g., tumuli). It is proposed that the lava flows were initially emplaced as sheet flows on low angle slopes (
How many species of the aquatic sloth Thalassocnus (Xenarthra: Megatheriidae) were in Chile?: new evidences from the Bahía Inglesa Formation, with a reappraisal of their biochronological affinities
Authors: Peralta-Prato Javiera , Solórzano Andrés
Published: October 2019

The aquatic sloth, Thalassocnus, is one of the most intriguing lineage of mammal known from the southern pacific coast of South America during the late Neogene. It was initially recognized in Perú, but recent paleontological surveys also recorded its presence in Chile. However, the determination of how many species of Thalassocnus were actually present in Chile remains as an open question. Here, we provide a detailed morphological description of an isolated distal fragment of humerus recovered at the Mina Fosforita member (ca. 7 Ma), Bahía Inglesa Formation (Atacama Region, northern Chile), which is referred to Thalassocnus. Morphological comparisons with others forms from Chile and Perú allow us to attribute the CPUC/C/557 specimen to Thalassocnus cf. T. natans, though some degree of intraspecific variation is acknowledged. The assessment of the stratigraphic provenance of the materials with previously assigned to Thalassocnus from the Bahía Inglesa, Horcón and Coquimbo formations, permits us to propose that the taxonomic diversity of Thalassocnus in Chile is unequivocal conformed by T. carolomartini, and T. natans. We also admitted the likely presence of T. antiquus and probably T. yaucensis. Futures discoveries of more complete specimens, and/or the detailed analysis of undescribed specimens from Chile will undoubtedly contribute to illustrate the evolutionary history of the Thalassocnus radiation in Chile.

Authors: Abu Samah, PhD Asnarulkhadi , Zaremohzzabieh, PhD Zeinab , Shaffril, PhD Hayrol Azril Mohamed , D’Silva, PhD Jeffrey Lawrence , Kamarudin, MA, PhD Candidate Syafila
Published: October 2019

There have been an increasing number of studies conducted on community preparedness, particularly on changing individual health behaviors in ways that minimizes individual risk to cope with the stress of a natural disaster. A variety of behavioral change theories and models used by disaster academics scrutinize the manner in which individual behavior is sought and transformed into disaster preparedness. This reflects the lack of knowledge about how these models identify certain behaviors regarding natural disaster preparation. This article seeks to address this lack of knowledge. It presents a set of health behavioral change models that can be used by scholars to comprehend variation in the nature and extent of individual disaster preparedness. The purpose of this study is to provide a review of the existing models on the subject, and also to present a comparative analysis of the models that may contribute to ways of understanding the investigation on natural disaster preparedness behaviors.

Authors: Kosteniuk Julie , Stewart Norma J. , Wilson Erin C. , Penz Kelly L. , Martin-Misener Ruth , Morgan Debra G. , Karunanayake Chandima , MacLeod Martha L. P.
Published: October 2019

Objective: This study examined accessibility of communication tools in the workplace, use of education to update nursing knowledge, and use of information to make specific decisions in practice among registered nurses (RNs) and licensed practical nurses (LPNs) in rural and remote communities in Canada.Methods: Data were analyzed from the cross-sectional survey, “Nursing Practice in Rural and Remote Canada II,” of regulated nurses practicing in all provinces and territories of Canada. Data were collected from April 2014 to August 2015.Results: The survey was completed by 3,822 of 9,622 nurses (40% response), and the present analysis was conducted with a subsample of 2,827 nurses. High-speed Internet was the most accessible communication tool, and nurses used “online/electronic education” more often than “in-person education” to update their nursing knowledge. Internet searches were used more often than several other online/electronic sources to inform decision making. Compared to LPNs, RNs reported greater workplace access to most communication tools and greater use of online/electronic education as well as information sources in online/electronic and print formats. Compared to nurses in community-based health care and hospital settings, nurses in long-term care settings reported lower access to most communication tools, lower use of online/electronic and in-person education, and lower use of online/electronic information.Conclusions: Access to continuing education and up-to-date information is important for effective patient care. This study points to a need for further research on the continuing education and information needs of rural and remote RNs and LPNs, and on their capacity to incorporate and apply new knowledge in practice.
The institutional repository landscape in medical schools and academic health centers: a 2018 snapshot view and analysis
Authors: Kipnis Daniel G. , Palmer Lisa A. , Kubilius Ramune K.
Published: October 2019

Objective: This study uses survey research methods to gain a deeper understanding of the institutional repository (IR) landscape in medical schools and academic health centers.Methods: Members of the Association of Academic Health Sciences Libraries (AAHSL) were surveyed about their IRs. The authors used a mixed-methods approach of a survey and qualitative content analysis to identify common themes.Results: Survey results indicate that a large majority of responding medical schools and academic health centers have or are implementing an IR (35 out of 50, 70%). Of these, 60% (21 institutions) participate in an institution-wide IR rather than administer their own repositories. Much of the archived content is grey literature that has not already been published, but the percentage of original content varies greatly among institutions. The majority (57.1%) of respondent institutions are not considering an open access policy or mandate. Most institutions (71.4%) reported that repository staff are depositing materials on behalf of users. dSPACE and bepress Digital Commons are the most popular repository platforms in this community. The planned enhancements that were most frequently reported were implementing a discovery layer and ORCID integration. The majority of respondents (54.3%) do not plan to migrate to a different platform in the foreseeable future. Analysis of respondent comments identified the following themes: integration, redundancy, and reporting; alternatives and exploration; uniqueness; participation; and funding and operations.Conclusions: The study results capture a view of the IR landscape in medical schools and academic health centers and help readers understand what services their peers have in place as well as their plans for future developments. This article has been approved for the Medical Library Association’s Independent Reading Program.
Information seeking and evaluation: a multi-institutional survey of veterinary students
Authors: Eldermire Erin R. B. , Fricke Suzanne , Alpi Kristine M. , Davies Emma , Kepsel Andrea C. , Norton Hannah F.
Published: October 2019

Objective: To practice evidence-based medicine, clinicians must be competent in information literacy (IL). Few studies acknowledge the critical role that reading strategies play in IL instruction and assessment of health professional students. The purpose of this study was to understand the information-seeking and evaluation behaviors of doctor of veterinary medicine (DVM) students in regard to scientific papers.Methods: The authors studied DVM student behaviors across eight programs in North America using a web-based survey of closed- and open-ended questions about finding and evaluating scientific papers, including a task to read a linked scientific paper and answer questions about it.Results: A total of 226 individuals responded to the survey. The sections of a scientific paper that were most commonly read were the abstract, introduction, and conclusions. Students who reported reading a higher proportion of scientific papers were more likely to feel confident in their abilities to interpret them. A third of respondents answered open-ended questions after the paper reading task. Respondents felt the least amount of confidence with one of the final steps of evidence-based medicine, that of interpreting the significance of the paper to apply it in veterinary medicine.Conclusions: DVM students may lack the skills needed to evaluate scientific literature and need more practice and feedback in evaluating and interpreting scientific papers. Librarians who support DVM students can (1) help DVM students to efficiently evaluate scientific literature, (2) seek training opportunities in alternative modes of teaching and learning IL skills, and (3) partner with veterinary faculty and clinicians to provide students with practice and feedback in information evaluation.

All too often the quality and rigor of topic investigations is inaccurately conveyed to information professionals, resulting in a mischaracterization of the research, which, if left unchecked and published, may in turn mislead potential readers. Accurately understanding and categorizing the types of topic investigation searches that are requested of information professionals is critical to both meeting requestors’ needs and reflecting their intended methodological approaches. Information professionals’ expertise can be an invaluable resource to guide users through the investigative and publication process.
Building the Systematic Review Core in an academic health sciences library
Authors: Lackey Mellanye J. , Greenberg Heidi , Rethlefsen Melissa L.
Published: October 2019

Background: The authors present efforts to build capacity at our institution for conducting systematic reviews and other forms of evidence synthesis through partnerships and a recharge model. This report describes how we successfully created and launched a for-fee systematic review core at our library.Case Presentation: Throughout 2014 and 2015, library leadership proposed different models for getting institutional and financial support for librarians and staff to better support university researchers conducting systematic reviews. Though well received, initial requests for financial support were not funded. The executive director of the Health Sciences Library released two years’ worth of salary and benefits to fund an evidence synthesis and retrieval librarian position. With this new position, the team formed a charge-back core facility in partnership with our university’s Clinical Translation and Science Award hub. A series of procedural decisions and operational changes helped the group achieve success. Within eighteen months after launching the Systematic Review Core, we reached maximum capacity with more than twenty ongoing reviews.Discussion: Assigning a dollar value to our expertise put us on par with other subject matter experts on campus and actually drove demand. We could act as paid consultants in research projects and shifted the perception of librarians from service providers to research partners. Affiliating with our partners was key to our success and boosted our ability to strengthen our campus’ research infrastructure.

Creating a new “reality” for medical education: the Nexus Reality Lab for virtual reality
Authors: Lilly Jason , Kaneshiro Kellie N. , Misquith Chelsea , Dennett Brandon
Published: October 2019

Background: The Technology Team at the Ruth Lilly Medical Library, Indiana University (IU), first started exploring virtual reality (VR) in 2016. In 2017, we began offering weekly sessions dubbed VRidays (“VR Fridays”) to give students an opportunity to experience the technology. We also purchased a portable VR setup that allowed us to demonstrate VR at our regional campuses.Description: To lower the entry barrier to VR, the Technology Team collaborated with the IU Advanced Visualization Lab to establish a reality lab in our collaborative learning space. The lab opened in the fall of 2018 and consists of four high-end VR stations that are accessible to students at any time, but they can also make an appointment for a more guided experience. Information and instructions are available on a LibGuide.Conclusion: We are currently collecting data on the number of unique users and evaluating application usage. We are working on a feedback mechanism and looking to develop collaborative partnerships across the university.Virtual Projects are published on an annual basis in the Journal of the Medical Library Association (JMLA) following an annual call for virtual projects in MLAConnect and announcements to encourage submissions from all types of libraries. An advisory committee of recognized technology experts selects project entries based on their currency, innovation, and contribution to health sciences librarianship.

Published: October 2019

As librarians are generally advocates of open access and data sharing, it is a bit surprising that peer-reviewed journals in the field of librarianship have been slow to adopt data sharing policies. Starting October 1, 2019, the Journal of the Medical Library Association (JMLA) is taking a step forward and implementing a firm data sharing policy to increase the rigor and reproducibility of published research, enable data reuse, and promote open science. This editorial explains the data sharing policy, describes how compliance with the policy will fit into the journal’s workflow, and provides further guidance for preparing for data sharing.

Published: October 2019

El propósito de este trabajo ha sido conocer el nivel de aprendizaje percibido y la satisfacción general con una experiencia educativa consistente en una propuesta expresivo-corporal implementada con WebQuest (WQ) en los niveles educativos de Primaria, Secundaria y Universidad. Se concibió como un estudio de caso múltiple en el que participaron tres profesoras con su respectivo alumnado (124 estudiantes en total, de 5 grupos de clase) y en el que se emplearon diferentes instrumentos de recogida de información: entrevistas y diarios con el profesorado, utilizándose con el alumnado cuestionarios y análisis de documentos como blogs, diarios grupales e individuales. Los datos fueron analizados mediante un análisis de contenido cualitativo con la ayuda del programa informático Atlas.ti versión 7. Los criterios que garantizan la calidad y credibilidad del estudio son, entre otros, el tiempo prolongado en el campo, el exhaustivo y reiterativo proceso de categorización y análisis de datos y la triangulación metodológica de instrumentos y participantes en los tres contextos educativos. Las conclusiones muestran que las competencias y objetivos didácticos diseñados en las propuestas educativas se han alcanzado adecuadamente. Específicamente, una gran parte del alumnado y las tres profesoras perciben haber aprendido especialmente conocimientos de tipo procedimental, tanto de Expresión Corporal (EC) como tecnológicos, a través de las WQ realizadas y se sienten satisfechos con la experiencia educativa desarrollada a través de este recurso didáctico.
¿Cómo describen, analizan y valoran los futuros maestros su formación lectora?
Authors: Álvarez-Álvarez Carmen , Diego-Mantecón José Manuel
Published: October 2019

Estudios recientes han planteado que los futuros maestros no son lectores expertos y tienen serias limitaciones al enfrentarse a textos literarios. Sin embargo, desconocemos cómo describen, analizan y valoran su formación lectora. En este artículo analizamos, mediante entrevistas semiestructuradas, la trayectoria lectora de 15 futuros profesores de educación primaria, desde su infancia hasta finalizar sus estudios universitarios. Los resultados muestran que la mayoría de los sujetos evaluados: (1) carecen de hábito lector y mantienen una visión instrumental de la lectura y la literatura; (2) sugieren que su paso por la Educación Primaria y Secundaria no ha supuesto para ellos un estímulo en el conocimiento de prácticas de animación a la lectura; y (3) valoran la formación pedagógica recibida en la carrera como insuficiente. Todos coinciden, sin embargo, en (4) su compromiso como dinamizadores de la lectura en su futuro como profesores. Este estudio evidencia, a diferencia de estudios anteriores, que el futuro profesor de primaria reconoce sus carencias en cuanto a su formación lectora, y señala la necesidad de abordar con prontitud este problema que incide directamente en la competencia lectora de nuestros escolares.
El papel del profesorado y el entorno de aprendizaje en el rendimiento de los estudiantes costarricenses: un análisis a partir de PISA
Authors: Gimenez Gregorio , Barrado Beatriz , Arias Rafael
Published: October 2019

The role of teachers and the learning environment in academic achievement of Costa Rican students: An analysis from PISAA pesar de que la literatura ha señalado que la calidad del profesorado y el ambiente escolar son factores clave en el rendimiento académico, los estudios que cuantifican empíricamente en qué medida contribuyen al desempeño estudiantil en los países latinoamericanos son escasos. En este artículo, utilizamos datos de PISA-Costa Rica y la técnica de descomposición Shapley-Shorrocks para cuantificar qué porcentaje de la variabilidad de los resultados escolares puede ser explicada por el profesorado y el entorno de aprendizaje. Los resultados muestran que la mayor parte de las diferencias en notas se debe al esfuerzo de cada estudiante (parte no explicada por la función de producción educativa).

Del resto de factores, las características de la escuela y del profesor explican más variabilidad en rendimiento (36% para el promedio de Matemáticas, Lectura y Ciencias) que el efecto conjunto de las circunstancias individuales y familiares (12,5%). Dentro de los factores de escuela, dos elementos tendrían especial relevancia. Por un lado, el comportamiento de los alumnos, destacando los problemas de absentismo e impuntualidad. Por otro, el nivel de autonomía del profesorado y la dirección de la escuela en el diseño de los planes de estudio y las evaluaciones.
Understanding the connection of Performance and Z-Scores for Manufacturing Firms in South Korea
Authors: Liang Foo See , Pathak Shaak
Published: October 2019

South Korea is a key leading economy in the Asia Pacific region. This study examines the relationship between the financial health, as measured by the Altman Z-Score, and corporate performance, as measured by the Return on Equity (ROE), of listed manufacturing companies in this market. A linear regression has been conducted between these variables to determine the magnitude and direction of their relationships. The trends of Z-Scores over a five-year period have also been analysed. The analysis covers the period from 2013 to 2017 (inclusive) and yields a statistically positive correlation between ROE and the Z-Score for the market. South Korea registered moderate mean and median Z-Scores. These findings further support the strong economic position of this market as an Asian giant.
Pseudo-static analysis of piles subjected to lateral spreading
Authors: Cubrinovski Misko , Ishihara Kenji , Poulos Harry
Published: October 2019

Soil liquefaction during strong ground shaking results in almost a complete loss of strength and stiffness in the liquefied soil, and consequent large ground deformation. Characteristics of the liquefied soils and loads on piles are significantly different during the cyclic phase and in the subsequent lateral spreading phase. Thus, it is necessary to separately consider these two phases in the simplified analysis of piles. This paper describes a practical procedure for preliminary assessment of piles subjected to lateral spreading. Effects of a crust of non-liquefied soil at the ground surface, properties of liquefied soils and pile groups are discussed in relation to their modelling in the simplified pseudo-static analysis approach. Particular attention is given to the treatment of unknowns and uncertainties involved in the simplified analysis and the need for parametric studies.
The Mw 6.7 George Sound earthquake of October 15, 2007

Published: October 2019

The Mw 6.7 George Sound earthquake of October 15, 2007, occurred only a few kilometres offshore of Fiordland, within a region where the subduction zone of the Australian Plate beneath the Pacific Plate intersects the offshore extension of the Alpine Fault. Rapid response deployments of portable seismographs, a strong motion recorder and GPS receivers relatively close to the epicentre soon after the main shock allowed us to relate the event to thrusting at the subduction interface. The main shock moment tensor solution places the event at a shallow depth of 21 km. The sequence of aftershocks that followed the main event presents predominantly reverse faulting mechanisms with depths of 20 to 25 km. Earthquake re-locations using data recorded by the portable seismometers reveal a cluster of aftershocks at 17 to 25 km. This cluster defines a steeply SE-dipping plane, while another cluster at about 7-12 km depth images a NW-dipping plane within the overlying plate. Preliminary results from the seismic, geodetic and near-field strong motion geophysical data are consistent with rupture on an east dipping fault plane, presumed to be the subduction interface.
Seismic design of bridge structures with allowance for large relative girder movements to avoid pounding
Authors: Chouw Nawawi , Hao Hong
Published: October 2019

Pounding between bridge girders have been observed in almost all previous major earthquakes. This is because the gap size of conventional bridge expansion joint is usually only a few centimetres, which is not sufficient to preclude poundings owing to large relative displacements between bridge girders caused by the effect of varying vibration properties of adjacent bridge spans, varying ground motions at bridge supports and varying soil-structure interaction (SSI). In this work a new design of bridge expansion joint is introduced. Instead of tolerating pounding and providing possible mitigating measures, this new design approach enables large movement between bridge girders which makes a complete pounding preclusion possible. The new expansion joint is called Modular Expansion Joint (MEJ). The large movability is achieved by installing a number of small gaps in the joint. In this study, the MEJ gap size required to completely avoid girder pounding is investigated. The most significant influence factors – the varying vibration properties of adjacent bridge spans, the effect of SSI and ground motion spatial variation on expansion joint size required to preclude pounding- are calculated. Discussions on the relative importance of various structural and ground motion properties in generating relative displacements of adjacent bridge girders are made.

This note is a comment on a recent paper in this journal by Moti Mizrahi. Mizrahi claims that the factivity of knowledge entails that knowledge requires epistemic certainty. But the argument that Mizrahi presents does not proceed from factivity to certainty. Instead, it proceeds from a premise about the relationship between grounds and knowledge to the conclusion about certainty.

‘Subways are Not Outdated’: Debating the Montreal Metro, 1940–60
Authors: Gilbert Dale , Poitras Claire
Published: October 2019

This article discusses how a subway was represented in debates on its merits as public transit for Montreal, Canada, during the 1940s and 1950s. Opponents argued that subways were obsolete in the automobile age, but supporters saw subway construction as a key tool for stimulating urban development and maintaining the city's prestige in the context of rising competition from Canada's second city, Toronto. Subway supporters regarded the project as being complementary to expressway construction, not as an alternative. A new technology developed in France provided the symbolic power that brought the project to fruition, beginning in 1960.
Simultaneous excitation of leaky mode resonance and surface plasmon resonance in tilted fiber Bragg grating
Authors: Li Zhihong , Ruan Xiukai , Dai Yuxing
Published: October 2019

This paper presents the first work that theoretically demonstrates simultaneous excitation of both enhanced leaky mode resonance (eLMR) and surface plasmon resonance in ultra-thin Au film coated tilted fiber Bragg grating. The mechanism is discussed by investigating the influence of Au film on mode characteristics of leaky modes and guided modes. A stable transmission spectrum that is only composed of strong dense comb-like eLMR in a wide window is realized. The eLMR excited by metal film exhibits insensitive response to external perturbation, which makes it ideal for tunable devices like optical filters and fiber lasers.
CD36 identified by weighted gene co-expression network analysis as a hub candidate gene in lupus nephritis
Authors: Yang Huiying , Li Hua
Published: October 2019

Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE), which often progresses to end-stage renal disease (ESRD) and ultimately leads to death. At present, there are no definitive therapies towards LN, so that illuminating the molecular mechanism behind the disease has become an urgent task for researchers. Bioinformatics has become a widely utilized method for exploring genes related to disease. This study set out to conduct weighted gene co-expression network analysis (WGCNA) and screen the hub gene of LN. We performed WGCNA on the microarray expression profile dataset of GSE104948 from the Gene Expression Omnibus (GEO) database with 18 normal and 21 LN samples of glomerulus. A total of 5,942 genes were divided into 5 co-expression modules, one of which was significantly correlated to LN. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted on the LN-related module, and the module was proved to be associated mainly with the activation of inflammation, immune response, cytokines, and immune cells. Genes in the most significant GO terms were extracted for sub-networks of WGNCA. We evaluated the centrality of genes in the sub-networks by Maximal Clique Centrality (MCC) method and CD36 was ultimately screened out as a hub candidate gene of the pathogenesis of LN. The result was verified by its differentially expressed level between normal and LN in GSE104948 and the other three multi-microarray datasets of GEO. Moreover, we further demonstrated that the expression level of CD36 is related to the WHO Lupus Nephritis Class of LN patients with the help of Nephroseq database. The current study proposed CD36 as a vital candidate gene in LN for the first time and CD36 may perform as a brand-new biomarker or therapeutic target of LN in the future.

Aims: To identify the prevalence of hypertensions, socio demographic characteristics, risk factor and awareness of the study population about hypertension in Khartoum Locality.

Study Design: A descriptive community-based cross-sectional study.

Place of Study: Khartoum locality, Sudan.

Methodology: A total of 587 adult participants were interviewed using structured close ended questionnaire. Blood pressure was measured considering hypertension as ≥ 140 mmHg and ≥ 90 mmHg for systole and diastole blood pressure respectively. Body Mass Index (BMI) was calculated and the cutoff points were derived from World Health Organization (WHO) reference criteria to classify BMI as normal, overweight and obese. Chi square test was used to assess the association of socio demographic characteristics and risk factors with hypertensive population.

Results: The prevalence of hypertensive accounted to 216 (36.8%).  Thirty seven hypertensive participants (17%) were not aware about having hypertension, 86 (40%) were not aware about at least one complication of HTN and 117(54%) were not aware about the normal measures of blood pressure. The hypertensive participants were significantly high in the age group 25- 64 years of age and above. Females were significantly having hypertension more than males, 155 (72%) versus 61 (28%). Married participants were significantly having hypertension more than non-married, 169(78%) and 47(22%) respectively. Unemployed participants were significantly having hypertension more than employed ones, 168 (77.8%) and 48 (22.2%) respectively.

Risk factors among hypertensive participants were significantly found among overweight 67 (31%) and obese 115 (53%), positive family history of hypertension 139 (65%), increase salt in food149 (69.3%) and physical inactivity 166 (77%).

Conclusion: The prevalence of hypertension among Khartoum locality was high.  Hypertensive population awareness was low. Age, sex, marital status, education and employment were significantly associated with hypertensive population. Obesity and overweight, family history of hypertension, increase salt in food and physical inactivity were risk factors among hypertensive study population.
Bistable switches as integrators and actuators during cell cycle progression

Progression through the cell cycle is driven by bistable switches—specialized molecular circuits that govern transitions from one cellular state to another. Although the mechanics of bistable switches are relatively well understood, it is less clear how cells integrate multiple sources of molecular information to engage these switches. Here, we describe how bistable switches act as hubs of information processing and examine how variability, competition, and inheritance of molecular signals determine the timing of the Rb‐E2F bistable switch that controls cell cycle entry. Bistable switches confer both robustness and plasticity to cell cycle progression, ensuring that cell cycle events are performed completely and in the correct order, while still allowing flexibility to cope with ongoing stress and changing environmental conditions.

Variants in GABRA1 have been associated with different epilepsies ranging from mild generalized forms to epileptic encephalopathies. Despite the broad clinical spectrum, phenotypes were found to be largely concordant within families. Contrary to this observation, we report monozygotic twin sisters with generalized epilepsy due to the c.541C>T; p.(Pro181Ser) de novo variant in GABRA1. One experienced juvenile absence seizures promptly responding to first‐line medication, whereas the second developed severe treatment‐refractory epilepsy with febrile, absence, atonic, and tonic‐clonic seizures indicating marked intrafamilial variability in GABRA1‐related epilepsy. Moreover, we provide a molecular characterization of the novel variant based on recently published structural data.
Full Energy Spectra of Interface State Densities for n‐ and p‐type MoS2 Field‐Effect Transistors

2D materials are promising to overcome the scaling limit of Si field‐effect transistors (FETs). However, the insulator/2D channel interface severely degrades the performance of 2D FETs, and the origin of the degradation remains largely unexplored. Here, the full energy spectra of the interface state densities (Dit) are presented for both n‐ and p‐ MoS2 FETs, based on the comprehensive and systematic studies, i.e., full rage of channel thickness and various gate stack structures with h‐BN as well as high‐k oxides. For n‐MoS2, Dit around the mid‐gap is drastically reduced to 5 × 1011 cm−2 eV−1 for the heterostructure FET with h‐BN from 5 × 1012 cm−2 eV−1 for the high‐k top‐gate. On the other hand, Dit remains high, ≈1013 cm−2 eV−1, even for the heterostructure FET for p‐MoS2. The systematic study elucidates that the strain induced externally through the substrate surface roughness and high‐k deposition process is the origin for the interface degradation on conduction band side, while sulfur‐vacancy‐induced defect states dominate the interface degradation on valance band side. The present understanding of the interface properties provides the key to further improving the performance of 2D FETs.

Grain boundaries (GBs) significantly affect the electrical, optical, magnetic, and mechanical properties of 2D materials. An anisotropic 2D material like ReS2 provides unprecedented opportunities to explore novel GB properties, since the reduced lattice symmetry offers greater degrees of freedom to build new GB structures. Here the atomic structure and formation mechanism of unusual multidomain and diverse GB structures in the vapor phase synthesized ReS2 atomic layers are reported. Using high‐resolution electron microscopy, two major categories of GBs are observed in each ReS2 domain, namely, the joint GB including three structures, and the GBs formed from a reconstruction of Re4‐chains including seven different structures. Based on the experimental observations, a novel “nanoassembly growth model” is proposed to elucidate the growth process of ReS2, where three types of Re4‐chain reconstruction give rise to a multidomain structure. Moreover, it is shown that by controlling the thermodynamics of the growth process, the structure and density of GB in the ReS2 domain can be tailored. First‐principles calculations point to interesting new properties resulting from such GBs, such as a new electron state or ferromagnetism, which are highly sought after in the construction of novel 2D devices.

Large‐bandgap perovskites offer a route to improve the efficiency of energy capture in photovoltaics when employed in the front cell of perovskite–silicon tandems. Implementing perovskites as the front cell requires an inverted (p–i–n) architecture; this architecture is particularly effective at harnessing high‐energy photons and is compatible with ionic‐dopant‐free transport layers. Here, a power conversion efficiency of 21.6% is reported, the highest among inverted perovskite solar cells (PSCs). Only by introducing a secondary amine into the perovskite structure to form MA1−xDMAxPbI3 (MA is methylamine and DMA is dimethylamine) are defect density and carrier recombination suppressed to enable record performance. It is also found that the controlled inclusion of DMA increases the hydrophobicity and stability of films in ambient operating conditions: encapsulated devices maintain over 80% of their efficiency following 800 h of operation at the maximum power point, 30 times longer than reported in the best prior inverted PSCs. The unencapsulated devices show record operational stability in ambient air among PSCs.

Insertion‐type anode materials with beneficial micro‐ and nanostructures are proved to be promising for high‐performance electrochemical metal ion storage. In this work, heterostructured TiO2 shperes with tunable interiors and shells are controllably fabricated through newly proposed programs, resulting in enhanced pseudocapacitive response as well as favorable Na+ storage kinetics and performances. In addition, reasonably designed nanosheets in the extrinsic shells are also able to reduce the excess space generated by hierarchical structure, thus improving the packing density of TiO2 shperes. Lastly, detailed density functional theory calculations with regard to sodium intercalation and diffusion in TiO2 crystal units are also employed, further proving the significance of the surface‐controlled pseudocapacitive Na+ storage mechanism. The structure design strategies and experimental results demonstrated in this work are meaningful for electrode material preparation with high rate performance and volume energy density.
