Thousands of health systems are now recognized as “Age‐Friendly Health Systems,” making this model one of the most widely disseminated – and most promising‐ models to redesign care delivery for older adults. Sustaining these gains will require demonstrating the impact on care delivery and outcomes of older adults. We propose a new measurement model to more tightly link Age‐Friendly Health System transformation to outcomes within each “M” (What Matters, Medications, Mobility, and Mentation). We evaluated measures based on the following characteristics: (1) conceptual responsiveness to changes brought about by practicing “4Ms” care; (2) degree to which they represent outcomes that matter to older adults; and (3) how they can be feasibly, reliably, and validly measured. We offer specific examples of how novel measures are currently being used where available. Finally, we present measures that could capture system‐level effects across “M”s. We tie these suggestions together into a conceptual measurement model for AFHS transformation, with the intent to spur discussion, debate, and iterative improvement in measures over time.
Temporal Orientation and Corporate Social Responsibility: Global Evidence
Authors: Choi Jongmoo Jay , Kim Jimi , Shenkar Oded
Published: August 2022

There has been a growing emphasis on the importance of a long‐term perspective in academia and practice. Yet understanding of the interdependency of those factors – the temporal preferences embedded in organizations and in societal values as well as the influence of temporal orientation of investors – remains limited. We theorize whether and how a firm's corporate social responsibility (CSR) is affected by the societal temporal orientation, its time horizon, and its investors' time horizon. Using a global sample, we confirm that CSR activity is higher when a country has a long‐term orientation culture, when the firm has a long‐time horizon, and when the controlling institutional investor has a long‐term investment horizon. We also find that the national culture's long‐term orientation heightens the effect of a firm's long‐time horizon on its CSR. Further, our results show that the effects of temporal orientation are more pronounced in environmental than in social CSR.

Published: August 2022

Obstructive sleep apnea is known to be an overall public health problem that, among other things, increases morbidity and mortality. Risk factors as well as symptoms of this multidimensional sleep‐related breathing disorder negatively affect quality of life. With our study we aimed to expose the association between obstructive sleep apnea and quality of life in the population of Pomerania, Germany. We utilized data from the population‐based Study of Health in Pomerania (SHIP). Information on health status and risk factors about 4420 participants (2275 women) were gathered within the cohort SHIP‐TREND, of which 1209 (559 women) underwent an overnight polysomnography and completed sleep questionnaires. The quality of life of the participants was measured using the Short‐Form 12 questionnaire. For our study, an ordinal regression analysis with age, sex, body mass index and the Short‐Form 12 health survey as predictors for apnea–hypopnea index was computed. The potential factors affecting quality of life are different between physical and mental dimensions of quality of life. Significant effects were found regarding age, sex, body mass index and the Short‐Form 12 Mental Component Score, but not the Physical Component Score.
Performance feedback and productivity: Evidence from a field experiment
Authors: Awaysheh Amrou , Bonet Rocio , Ortega Jaime
Published: August 2022

We theorize that employees use the performance feedback they receive to reassess their beliefs about the marginal benefit of their effort, which may lead them to increase or reduce their effort. To test our model, we conduct a field experiment at the distribution center of a Fortune 500 firm where employees receive individual performance pay, and we study two types of feedback, individual and relative. The results show that employees react to feedback content in a way that is consistent with the model: They increase their effort if the information provided implies that the marginal benefit of increasing effort is high and decrease it if they learn that it is low. Moreover, performance feedback has a greater impact on the lower quantiles of the distribution of productivity.
Algorithmic fairness in business analytics: Directions for research and practice
Authors: De‐Arteaga Maria , Feuerriegel Stefan , Saar‐Tsechansky Maytal
Published: August 2022

The extensive adoption of business analytics (BA) has brought financial gains and increased efficiencies. However, these advances have simultaneously drawn attention to rising legal and ethical challenges when BA inform decisions with fairness implications. As a response to these concerns, the emerging study of algorithmic fairness deals with algorithmic outputs that may result in disparate outcomes or other forms of injustices for subgroups of the population, especially those who have been historically marginalized. Fairness is relevant on the basis of legal compliance, social responsibility, and utility; if not adequately and systematically addressed, unfair BA systems may lead to societal harms and may also threaten an organization's own survival, its competitiveness, and overall performance. This paper offers a forward‐looking, BA‐focused review of algorithmic fairness. We first review the state‐of‐the‐art research on sources and measures of bias, as well as bias mitigation algorithms. We then provide a detailed discussion of the utility–fairness relationship, emphasizing that the frequent assumption of a trade‐off between these two constructs is often mistaken or short‐sighted. Finally, we chart a path forward by identifying opportunities for business scholars to address impactful, open challenges that are key to the effective and responsible deployment of BA.
Antecedents and consequences of servant leadership in local governance: Evidence from three case studies
Authors: Awasthi Pallavi , Walumbwa Fred O.
Published: August 2022

Although servant leadership has emerged as an important community‐oriented leadership approach that is desirable for public organizations, relatively less research attention has been devoted to understanding its antecedents as well as its organizational and community‐level consequences. Drawing on self‐categorization and stakeholder theories, this study investigates the antecedents and consequences of servant leadership in local government agencies using a comparative analysis of three case studies (two counties and a city). Findings highlight two frameworks of antecedents and consequences of servant leadership in local governance: (1) the underlying mechanisms—translating antecedents into servant leadership and (2) the intervening mechanisms—translating as organizational and community‐level consequences of servant leadership. These findings have implications for both public sector leadership theory and practice. Theoretically, servant leadership emerges as an inclusive approach that fosters stakeholder engagement and community prosperity in local governments. Practically, the findings suggest a pathway for utilizing servant leadership as an instrument for potential selection, training, succession planning, and servant leadership development in local government managers.
Confidence deficits and reducibility: Toward a coherent conceptualization of uncertainty level
Authors: Janzwood Scott
Published: August 2022

Outside of the field of risk analysis, an important theoretical conversation on the slippery concept of uncertainty has unfolded over the last 40 years within the adjacent field of environmental risk. This literature has become increasingly standardized behind the tripartite distinction between uncertainty location, the nature of uncertainty, and uncertainty level, popularized by the “W&H framework.” This article introduces risk theorists and practitioners to the conceptual literature on uncertainty with the goal of catalyzing further development and clarification of the uncertainty concept within the field of risk analysis. It presents two critiques of the W&H framework's dimension of uncertainty level—the dimension that attempts to define the characteristics separating greater uncertainties from lesser uncertainties. First, I argue the framework's conceptualization of uncertainty level lacks a clear and consistent epistemological position and fails to acknowledge or reconcile the tensions between Bayesian and frequentist perspectives present within the framework. This article reinterprets the dimension of uncertainty level from a Bayesian perspective, which understands uncertainty as a mental phenomenon arising from “confidence deficits” as opposed to the ill‐defined notion of “knowledge deficits” present in the framework. And second, I elaborate the undertheorized concept of uncertainty “reducibility.” These critiques inform a clarified conceptualization of uncertainty level that can be integrated with risk analysis concepts and usefully applied by modelers and decisionmakers engaged in model‐based decision support.
Asymptotics of the deformed Fredholm determinant of the confluent hypergeometric kernel
Authors: Dai Dan , Zhai Yu
Published: August 2022

In this paper, we consider the deformed Fredholm determinant of the confluent hypergeometric kernel. This determinant represents the gap probability of the corresponding determinantal point process where each particle is removed independently with probability , . We derive asymptotics of the deformed Fredholm determinant when the gap interval tends to infinity, up to and including the constant term. As an application of our results, we establish a central limit theorem for the eigenvalue counting function and a global rigidity upper bound for its maximum deviation.
Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club
Authors: Turnbull Jonathon , Searle Adam , Lorimer Jamie
Published: August 2022

This paper offers a detailed empirical account of how human–environment relations were reconfigured in the UK and Ireland during the 2020–2021 COVID‐19 lockdowns, a period which natural scientists defined as the COVID‐19 Anthropause. Bringing this scientific concept into conversation with geographical work, we consider anthropause as both a lived condition and an historical moment of space–time decompression. Our expanded conceptualisation of anthropause, centred on lived experience and everyday life, develops a more hopeful politics than those offered by the ‘Great Acceleration’ narrative, which suggests digital media and urbanisation separate humans from nature. In contrast, we identify affirmative and inclusive modes of ‘anthropause environmentalism’ and explore their potential for fostering convivial human–nature relations in a world that is increasingly urban, digital, and powered by vernacular expertise. To make this argument, we turn to the Self‐Isolating Bird Club, an online birdwatching community operating across several social media platforms which, at the pandemic's height, reached over 50,000 members. We trace three key changes to human–nature relations illustrated by this group which we use to structure our paper: connection, community and cultivation. The COVID‐19 Anthropause recalibrated the fabric and rhythms of everyday life, changing what counts as a meaningful human–nature relationship. This paper will be of interest to geographers exploring environmental change at the interface of more‐than‐human and digital geographies, as well as environmentalists and conservationists. To conclude, we offer suggestions as to how scholars and practitioners might harness the lessons of anthropause to respond to the ‘anthropulse’.
Moduli of surfaces in
Authors: DeVleming Kristin
Published: August 2022

The main goal of this paper is to construct a compactification of the moduli space of degree $d \geqslant 5$ surfaces in $\mathbb {P}^{3}_{{{\mathbb {C}}}}$, i.e. a parameter space whose interior points correspond to (equivalence classes of) smooth surfaces in $\mathbb {P}^{3}$ and whose boundary points correspond to degenerations of such surfaces. We consider a divisor $D$ on a Fano variety $Z$ as a pair $(Z, D)$ satisfying certain properties. We find a modular compactification of such pairs and, in the case of $Z = {{\mathbb {P}}}^{3}$ and $D$ a surface, use their properties to classify the pairs on the boundary of the moduli space.
Numerically non-special varieties
Authors: Pereira Jorge Vitório , Rousseau Erwan , Touzet Frédéric
Published: August 2022

Campana introduced the class of special varieties as the varieties admitting no Bogomolov sheaves, i.e. rank-one coherent subsheaves of maximal Kodaira dimension in some exterior power of the cotangent bundle. Campana raised the question of whether one can replace the Kodaira dimension by the numerical dimension in this characterization. We answer partially this question showing that a projective manifold admitting a rank-one coherent subsheaf of the cotangent bundle with numerical dimension one is not special. We also establish the analytic characterization with the non-existence of Zariski dense entire curve and the arithmetic version with non-potential density in the (split) function field setting. Finally, we conclude with a few comments for higher codimensional foliations which may provide some evidence towards a generalization of the aforementioned results.

Authors: Velez Bohorquez Anggi Margarita , Vélez Bohórquez Daniel Javier , Bohórquez Lozano Mabel Elena , Cecilia Rios Angela
Published: August 2022

Introduction: The frozen section procedure is an intraoperative diagnostic method widely used and useful for surgical decision making; which minimizes costs and optimizes staging. Objectives: This research assesses the diagnostic accuracy of frozen section in an intermediate care center, analyzes the factors that may be involved in misdiagnosis and compares the results of the original study with other studies. Materials and methods: This is a cross-sectional study in which the diagnostic accuracy was evaluated and a univariate analysis was performed in a sample of 417 cases that underwent a frozen section. The characteristics of the samples were registered along with the concordance or discordance between the frozen section and the final diagnosis. In addition, a systematic review was made using the Pubmed database in order to compare results with previous studies. Results: The sample included predominantly females with a mean age of 50 years. The sensitivity and specificity of malignancies was 89% and 100% respectively and the sensitivity for borderline tumors was lower (73%). Specimens equal or larger than 10cm and patients with age ≥ 50 years showed association to misdiagnosis when using frozen sections. For example, the analysis of 300 ovary specimens showed association to misdiagnosis in borderline, epithelial and stromal tumors. Conclusions: The frozen sections continue to be the best tool for quick intraoperative diagnostic, and even with some inaccuracies in the diagnosis, this don’t harm the clinical and surgical practice.
Rol del lactato en pacientes con falla hepática
Authors: Lombo Moreno Carlos Ernesto , Suarez Quintero Carmen Yanette
Published: August 2022

Desde finales del siglo XX, los niveles de lactato han sido estudiados como marcador pronostico en los pacientes críticamente enfermos y como meta en su reanimación. En pacientes con enfermedad hepática la interpretación de los niveles de lactato presenta cierta dificultad dado su mecanismo de producción fisiopatológico. Sin embargo, existe evidencia sobre la relación de los niveles de lactato y mortalidad en el paciente con enfermedad hepática aguda o crónica en el paciente críticamente enfermo. Además, se ha postulado el lactato como predictor de beneficio de trasplante hepático y marcador pronostico temprano posterior al trasplante hepático. De acuerdo con lo anterior, es relevante el estudio e interpretación adecuada del lactato en los pacientes con enfermedad hepática.

El triaje permite la priorización de pacientes según su urgencia médica. Se propone realizar un modelo estadístico correlacionado con mortalidad para generación de alertas desde el triaje.

Una cohorte prospectiva de 6438 adultos que ingresaron a urgencias del Hospital Universitario San Ignacio, del 01/03/2018 al 28/02/2019. Se dividieron aleatoriamente los datos en entrenamiento y prueba. Sobre los datos de entrenamiento se realizó una regresión logística bivariada entre triaje y mortalidad y luego una regresión logística multivariada, se redujo el modelo mediante pruebas de razón de verosimilitud. En los datos de prueba se realizaron áreas bajo la curva (AUC) para cálculo de punto de corte. Fue evaluado mediante medidas de asociación.

Se realizaron áreas bajo la curva para los modelos realizados, encontrando el modelo “triage” con de AUC 0.82, “reducido” una AUC 0.90 y “Edad+sistólica” una AUC 0.87, sin diferencia significativa. Se seleccionó “reducido” con una Sensibilidad 0.869, Especificidad 0.842, VPP: 0.062, VPN: 0.998

Para seleccionar punto de corte, se realizó un árbol de decisiones teniendo en cuenta las variables significativas encontrando mayor mortalidad en pacientes triage 1-2, con TAS menor de 117mmHg y mayores de 58 años.

El modelo final podría funcionar como tamización para generación de alarmas de mortalidad en triaje iguales.

Aprendizaje de la Estrategia AIEPI según método de enseñanza utilizado. Revisión sistemática de estudios comparativos.
Authors: Agudelo Acosta Sonia Consuelo , Granados Rugeles Claudia Marcela
Published: August 2022

Introducción: La Estrategia de la Atención Integrada de las Enfermedades Prevalentes de la Infancia (AIEPI) disminuye la morbimortalidad de los niños menores de 5 años. AIEPI clínico evalúa al niño integralmente, identifica patologías frecuentes, clasifica por gravedad e interviene. Conocer experiencias del proceso enseñanza-aprendizaje es fundamental para mejorar. Métodos: Revisión sistemática de publicaciones hasta el 30 de enero del 2021. Se seleccionaron estudios que compararan dos o más estrategias de enseñanza de AIEPI clínico o el antes del entrenamiento y el después. Resultados: De diez estudios encontrados, cuatro compararon el conocimiento antes del entrenamiento y después de este, cinco analizaron dos métodos de enseñanza y uno fue una revisión sistemática que comparó curso de larga vs. corta duración. Existe heterogeneidad en las estrategias didácticas y en la evaluación del aprendizaje, por lo que no se pudo realizar una síntesis cuantitativa. La enseñanza virtual tiene ventajas en cuanto a costos. La teoría, junto con actividades prácticas supervisadas, mejora las competencias obtenidas. Conclusiones: Contextualizar el AIEPI clínico es importante. Se sugiere crear una estrategia homogénea de evaluación para tener una referencia universal, definir los correctivos, los aspectos que no necesiten modificarse y evaluar a largo plazo qué conceptos se deben reforzar.
El debate ético y de regulación sobre el uso de CRISPR-Cas9 en la línea germinal humana
Authors: Díaz Amado Eduardo , González Angulo Ana María
Published: August 2022

Introducción: CRISPR-Cas9 es actualmente la herramienta más versátil en la ingeniería genética y, por su bajo costo y habilidad para editar genomas fácilmente, es usada por toda la comunidad científica. Ofrece promesas considerables en todo campo biológico y especialmente en la comunidad biomédica para curar enfermedades. Sin embargo, a pesar del apoyo general para su utilización clínica, existen preocupaciones éticas y, sobre todo, respecto a su eficacia y seguridad en el contexto de su uso para editar el genoma humano.
 Objetivo: Revisar la literatura académica y popular sobre los problemas y las implicaciones a considerar sobre el uso de CRISPR-Cas9 en la línea germinal humana.
 Métodos: Búsqueda en las bases de datos PubMed y Embase con términos indexados y libres, periódicos y libros de alta circulación.
 Resultados: Se seleccionaron 59 documentos según los criterios de inclusión y a partir de ellos, se crearon cuatro capítulos que revisan las limitaciones técnicas, las implicaciones éticas, la actividad regulatoria e implicaciones políticas y jurídicas respecto del uso de CRISPR-Cas9 en la línea germinal humana, así como las implicaciones para Colombia.
 Conclusiones: Aunque las limitaciones técnicas se superarán con avances tecnológicos, las preocupaciones éticas son permanentes y han llevado a declaraciones que van desde la prohibición o la moratoria, hasta su uso bajo condiciones estrictas. Colombia debe abordar los retos éticos y regulatorios intentando fortalecer sus capacidades institucionales y el debate público
COVID-19 y embarazo: repercusiones maternas y neonatales. Una revisión de la literatura
Authors: Maloof Geraldin , Rodriguez Maria Jose , Moreno Freddy
Published: August 2022

La enfermedad causada por el coronavirus SARS-CoV-2 puede generar consecuencias negativas durante la gestación. El objetivo de esta revisión de la literatura consistió en reportar las repercusiones maternas y neonatales asociadas a la infección por SARS-CoV-2. Por medio de una búsqueda sistematizada de la literatura en MEDLINE, utilizando las pautas de búsqueda de la Declaración PRISMA, se encontraron 15 publicaciones que describían las repercusiones más frecuentes en gestantes y neonatos más frecuentes: ingresos a Unidad de Cuidados Intensivos con necesidad de soporte ventilatorio invasivo, parto pretérmino, hemorragia posparto, trastornos hipertensivos, bajo peso al nacer, abortos y mortinatos. La información disponible sobre las repercusiones maternas y neonatales no es concluyente y todavía se desconoce si las repercusiones encontradas están relacionadas con la infección o son eventos aislados. La transmisión vertical es un evento inusual y los contagios en neonatos se deben fundamentalmente a la transmisión horizontal.

La secuencia rápida de intubación es el método de elección para el aseguramiento de la vía aérea en el servicio de urgencias, este procedimiento además del paso del tubo orotraqueal a través de la glotis consta de diferentes pasos los cuales se deben hacer de manera minuciosa y secuencial con el fin de lograr asegurar la vía aérea en el menor tiempo posible, con la menor cantidad de intentos e idealmente sin complicaciones asociadas. Debido a la importancia de este tema se han dado nuevas recomendaciones respecto a cada uno de los momentos de dicho procedimiento, partiendo de las indicaciones y contraindicaciones, enfoques para la preparación y planeación del abordaje de la vía aérea como las mnemotecnias MACOCHA y HEAVEN, el uso temprano de vasopresores y líquidos endovenosos para pacientes con riesgo de deterioro hemodinámico, el uso de diferentes técnicas para la preoxigenación como la ventilación mecánica no invasiva o la preoxigenación apneica. Además debemos individualizar cada paciente al elegir cada fármaco ya sea para premedicar, realizar hipnosis o relajación muscular. Adicionalmente técnicas nuevas como el uso de ultrasonografía para corroborar el adecuado posicionamiento del tubo orotraqueal y los cuidados postintubación. Todos estos tópicos serán abordados en esta revisión
Adsorption of Volatile Organic Compounds Onto Biomass-Derived Activated Carbons: Experimental Measurement and Comparison
Authors: Rupam Tahmid Hasan , Saha Bidyut Baran , Palash Mujib L. , Pal Animesh
Published: August 2022

Volatile organic compounds (VOCs) are a class of hazardous gaseous materials emitted from certain solids or liquids. They are thought to possess serious short- or long-term adverse effects on human health. Nowadays, an energy-efficient and cost-effective volatile organic compound removal system is of absolute necessity due to its adverse effects. In this regard, solar or waste heat-driven adsorption-based technologies can provide an energy-efficient system; however, most of the time, their utilization is limited by the high cost of the adsorbent materials. Right now, only one commercial high-grade activated carbon named Maxsorb III is known to have high capturing capacities. The purchasing cost of this adsorbent is very high, and it is derived from a non-renewable source. Therefore, this study is intended for the quest for low-priced biomass-derived activated carbons for an energy-efficient and cost-effective VOCs removal system. Two biomass-derived activated carbons synthesized from mangrove wood and waste palm trunk precursors are chosen, and four types of VOCs (ethanol, dichloromethane, acetone, and ethyl acetate) adsorption onto them are measured experimentally using the inverse gas chromatography technique. The zero uptake adsorption enthalpy and specific entropy of the adsorption are theoretically computed for all the adsorbent/adsorbate pairs. After that, these data are compared with the obtained data for Maxsorb III to assess the performance of the biomass-derived activated carbons. Results show that, for all the VOCs, the cost-effective mangrove-based activated carbon can be an excellent alternative to the high-priced Maxsorb III when employed as an adsorbent material for VOCs removal.
Review of Mechanisms and Research Methods for Blunt Ballistic Head Injury

Published: August 2022

Head injuries account for 15%–20% of all military injuries and pose a high risk of causing functional disability and fatality. Blunt ballistic impacts are one of the threats that can lead to severe head injuries. This review aims to examine the mechanisms and injury risk assessment associated with blunt ballistic head injury (BBHI). The review further discusses research methods and instrumentation used in BBHI studies, focusing on their limitations and challenges. Studies on the mechanisms of focal and diffuse brain injuries remain largely inconclusive and require further effort. Some studies have attempted to associate BBHIs with head mechanics, but more research is required to establish correlations between head mechanics and injury severity. Limited access to experimental models and a lack of instrumentation capable of measuring the mechanics of brain tissue in situ are potential reasons for the lack of understanding of injury mechanisms, injury correlations, and injury tolerance levels specific to this loading regime. Targeted research for understanding and assessing head injuries in blunt ballistic impacts is a necessary step in improving our ability to design protection systems to mitigate these injuries.

Parabolic trough concentrated solar power (CSP) plants are particularly promising renewable sources of energy, whose easy integration with thermal energy storage (TES) systems allows to mitigate the intermittency of electricity generation. Currently, molten nitrates, with two tanks arrangement, are mainly used for sensible heat accumulation. To reduce costs and make the CSP storage systems more manageable, single tank configurations have been proposed, where the cold and hot fluids are stored in the same container and separated because of their density difference. The aim of the present work is to study the storage performances presented by two novel ternary and quaternary mixtures, proposed within the European project IN POWER. An experimental campaign was preliminarily performed to investigate the fluids thermo-physical properties, and the obtained values were utilized as input data to model the discharge phase in a thermocline tank. The simulation results were compared with the ones acquired considering two commercial materials, namely, solar salt and Hitec XL®. Overall, considering same temperature ranges, higher discharging times are obtained for the quaternary and ternary mixtures, with the ternary presenting a smaller thermocline thickness than the solar salt while this parameter is the same considering the quaternary and Hitec XL®.

Published: August 2022

During a first faunistic survey on the eriophyoid mites of Meshginshahr rangelands in Ardabil province, Iran, two new Aceria species of eriophyid mites were found, and they are described and illustrated. They are: Aceria ayvatliorum Lotfollahi et Hemmatzadeh sp. nov. from Rhaponticum repens (L.) Hidalgo (Asteraceae), and Aceria beygdiliorum Lotfollahi et Hemmatzadeh sp. nov. from Astragalus compactus Lam. (Fabaceae). The first aforementioned new species is the third eriophyoid associated with R. repens. And the second new species is the fourth Aceria species found on Astragalus species. Both new species were vagrants, and no plant deformations were observed. Due to the presence of numerous endemic Astragalus species in Iran, an intensive and cohesive survey of eriophyoid mites of Astragalus is strongly suggested.

Published: August 2022

Fall armyworm Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) is a destructive, migratory pest that seriously damages corn, sorghum, and other crops. The “insect killer” Pyemotes zhonghuajia (Trombidiformes: Pyemotidae) is an ectoparasitic mite of agricultural and forestry pests in China. To explore the biological control efficiency of P. zhonghuajia on S. frugiperda, we evaluated the parasitic selectivity of P. zhonghuajia on S. frugiperda of different life stages, and distribution of P. zhonghuajia on different body parts of S. frugiperda larvae and pupae, food intake of S. frugiperda larvae affected by P. zhonghuajia density, and field population dynamics of S. frugiperda in relation to the releasing population density of P. zhonghuajia. We found that P. zhonghuajia preferred 4th- to sixth-instar larvae and pupae of S. frugiperda for parasitism, and the ventral part of abdominal segments of fourth-instar larvae and the ventral part of pupal thorax for feeding. Freezing of S. frugiperda 4th instar larvae and pupae had little effect on the distribution of P. zhonghuajia on the surface of these two host stages. The parasitism of P. zhonghuajia regardless of mite population size (i.e., 5, 10, or 20 mites) could significantly decrease the cumulative food intake of fifth-instar larvae of S. frugiperda. Releasing two and three boxes (50,000 mites/box) of P. zhonghuajia significantly suppressed the field population of S. frugiperda on sorghum plants/25 m2 within 7 days. Our results show that P. zhonghuajia may be a potential biological control agent and can be used for biological control of S. frugiperda in the field.
Spatial-resolution impacts on local infrasound propagation

Published: August 2022

The accuracy of input meteorological data can significantly impact the successful prediction of infrasound propagation at local to near-regional distances. These meteorological inputs are often derived from weather model simulations when event-specific measurements are not available, but the ideal spatial resolutions of these simulations have not been determined. This study seeks to identify the ideal horizontal resolutions for input meteorological data via infrasound simulations conducted with both range-dependent and -independent inputs. Outputs from the Weather Research and Forecasting (WRF) model at 1, 3, 5, and 15 km horizontal resolutions enable these investigations. The parabolic equation propagation model is used to calculate transmission loss for an impulsive signal and is compared against experimental data obtained from a series of 1 lb spherical, suspended C4 shots recorded on the infrasound array on the Waterways Experiment Station in Vicksburg, MS, occurring throughout the diurnal cycle with an overall propagation distance of 14.5 km. Simulations for morning and nighttime correctly predict signal detection and non-detection. Transitional times of day (dawn, evening) were partially successful. Changing horizontal resolutions in WRF incurred greater differences in prediction results than use of range-dependence vs -independence. No clear picture emerged regarding the optimal horizontal resolution for meteorological inputs.
One Long Versus 2 Short Sessions? Physiological and Perceptual Responses to Low-Intensity Training at Self-Selected Speeds in Cross-Country Skiers
Authors: Talsnes Rune Kjøsen , Nordgården Sigrid , Kocbach Jan , Solli Guro Strøm
Published: August 2022

Purpose: To compare self-selected speeds and corresponding physiological responses and perceived training stress between 1 long session versus 2 shorter sessions of low-intensity training (LIT) in 1 day among cross-country skiers. Methods: Thirteen national-level skiers performed 2 different LIT types during classical roller-skiing matched for the same distance in a counterbalanced order. The training consisted of either 1 long (approximately 3 h) session (1LIT) or 2 shorter (approximately 1.5 h each) sessions (2LIT) with 7 hours of recovery in between. Speed, heart rate, rating of perceived exertion, and blood lactate concentrations were measured, and perceived training stress (1–10) was assessed after sessions. Results: 2LIT was performed at mean (SD) 1.9% (2.0%) higher speeds versus 1LIT (P ≤ .01). Higher speeds were also found in the second versus first session of 2LIT and the second versus first part of 1LIT (1.9% [3.2%] and 3.2% [3.6%], respectively, both P ≤ .01). There were no significant differences between LIT types in heart rate, although rating of perceived exertion increased in the second versus first part of 1LIT (0.9 [0.8] point, P ≤ .01). Blood lactate concentration was reduced in the second versus first session/part of both LIT types (approximately 0.16 [0.20] mmol·L−1, P ≤ .05). There were no differences in perceived training stress between LIT types 7 and 23 hours after training, although higher perceived muscular exertion (2.0 [1.1] points, P ≤ .01) was found directly after 1LIT. Conclusions: Compared with a distance-matched long session, skiers perform 2LIT at slightly higher self-selected speeds with the same physiological responses elicited, although minor differences in perceived training stress were observed.

A common method for quantifying microbial abundances
in situ
is through metagenomic read recruitment to genomes and normalizing read counts as reads per kilobase (of genome) per million (bases of recruited sequences) (RPKM). We created RRAP (RPKM Recruitment Analysis Pipeline), a wrapper that automates this process using Bowtie2 and SAMtools.

We demonstrate that the EqHV dose of infection plays an important role for inducing immune responses, possibly linked to early clearance in high-dose and prolonged viremia in low-dose infections. In particular, pathways associated with innate and adaptive immune responses, as well as inflammatory responses, were more strongly upregulated in high-dose infections than in lower doses.

Molecular Dynamics Simulation of Argon and Argon–Water Systems
Authors: Malenkov G. G.
Published: August 2022

A molecular dynamics model is created for argon near the critical point. As the temperature falls at a constant density less than critical, It is established that a drop of liquid argon forms in the gas environment. This drop is not spherical, but cylindrical. Liquid argon near the melting point (110 K, density 1.513 g/cm3) is also modeled. The values of the Voronoi polyhedra volumes (VPVs) around argon atoms are calculated and their distribution is plotted. The VPV values lie in the range of 34–55 Å3, with an average value of 43.6 Å3. Argon atoms with low VPV values tend to combine with one another and form branching clusters, as is typical of atoms with high VPV values. Clusters formed by atoms with high and low VPV values are inserted into one another. Issues related to the behavior of argon atoms in argon–water systems are also considered.

Published: August 2022

The tasks of establishing an ecological network are presented, outlining some outcome of the long-term study of the Great Eurasian Natural Tract (Backbone), which is a continuous series of natural ecological systems from the Pacific Ocean to Fennoscandia. The story of the tract’s detection is briefly told as a modern geographical discovery. Its delineation is based on the map of Russia’s biomes resulting from remote-sensing analysis with field verification and other open data. Information about changing the area of natural ecosystems and variations of phytomass stock in various biomes are given. The authors give a monetary assessment of the ecosystem services of the Great Eurasian Natural Tract (GEANT), and a short-term forecast of changes in the productivity of its ecosystems is proposed. The issues of GEANT management are discussed: the inclusion of the concept of the ecological network in the Strategy for the Development of a System of Specially Protected Natural Areas in the Russian Federation for the Period up to 2030 and the creation of a state agency that would supervise the territorial conservation. It is proposed to consolidate the GEANT’s status legally as a unique world natural heritage.
Decaying universes and the emergence of Bell-type interuniversal entanglement in varying fundamental constants cosmological model
Authors: Balcerzak Adam , Lisaj Mateusz
Published: August 2022

In this paper, we consider a high-curvature limit of the varying fundamental constants toy model in which both the value of the speed of light and the value of the gravitational constant are related to the values of the two non-minimally coupled scalar fields. The high-curvature limit motivates the application of the third quantization procedure to such a toy model which results in a theory that describes bosonic massive particles that move freely in the three-dimensional minisuperspace associated with the degrees of freedom of the original model. Motivated by the idea that in the quantum cosmological description the minisuperspace gets promoted to a real configurational space of the system we supplement the third quantized action of the considered model with an interaction term that allows for decay and scattering processes. We show that such interaction term induces a scenario in which a parent universe decays into two universes described by a nearly maximally entangled Bell state. We eventually asses the strength of the entanglement, in the created pair of universes, by calculating the von Neumann entropy of entanglement.

The biological, chemical, and structural properties of molecular graphs can be predicted by using topological indices. The lower and upper bounds of fundamental topological indices are well-studied. In this paper, by using comparison theorem for integrals, we obtain new bounds for some topological indices namely, Randić index, Sombor index, harmonic index and forgotten index.
The Impact of Wetland Utilisation on Provisioning Ecosystem Services in Nyando Wetland, Kenya
Authors: Maithya Joseph K. , Ming’ate Felix L. M. , Letema Sammy C.
Published: August 2022

People’s livelihoods in developing countries are often directly dependent on wetlands and watersheds for the provision of food, water, fuel, wood, fibre, and genetic resources. The high rural population density within the Lake Victoria basin is facilitating the rapid conversion of land to settlement and agriculture. These activities have resulted in the depletion of wetland resources to the extent that they cannot replenish naturally, thus threatening the Nyando wetland ecosystem, potential recreational opportunities, and the livelihoods of local communities. This paper, therefore, examines the implication of Nyando wetland utilisation in provisioning ecosystem services. A case study survey design approach was employed for data collection. Both quantitative and qualitative data were collected to answer the study objectives. Stratified random sampling was conducted to collect data from 391 households using a structured questionnaire. An interview guide was also used to collect data from stakeholder representatives at the national and county governmental level, non-governmental organisations, and members of the local community. Descriptive statistics were used to analyse the quantitative data, while qualitative data were analysed through content analysis by ordering distinct themes into similar categories. A land-use change analysis was performed using an unsupervised classification technique. The results show that the local community depends on the wetland for farming, firewood, settlement, roofing and mat-making materials, and fishing for domestic and commercial use. The local community’s increased demand and utilisation of Nyando wetland resources has contributed to a reduction in the size of the wetland and consequently affected the availability of ecosystem services. Thus, sustainable utilisation of the wetland is needed.

Agriculture sector plays a crucial role in the development of the economic system for developing countries. Useful insights extracted from agricultural data would lead to a better economy in the upcoming future. It is hard to manually look for the ripened fruits for harvesting in a farmland of a big area. Automated image-based methods to identify the presence of fruits on a tree and determine the number of fruits present on the tree is a challenging problem. MangoNet architecture performs well in detecting the mangoes invariant. The proposed work improves the efficiency of the model by optimizing the dropout rate of the MangoNet architecture. Harris Hawks Swarm Optimization (HHO) algorithm is developed to tune the dropout rate of the model. The dropout rate is optimized using HHO in the architecture to avoid overfitting problem. The proposed method is compared with particle swarm optimization (PSO) and BAT algorithm (BA) which underestimate uncertainty. The simulation results exhibit improved accuracy over 80% when compared to other existing methods considered in this study. We show theoretically that this gives us the ability to capture uncertainty better than existing methods.
