Authors: Göknar İzzet Cem , Minayi Elham 
Published: November 2022

AbstractThe introduction of Add ‐ Differentiate IC, AD‐IC, a new integrated circuit, into schemes for realizing single input multiple output current mode filters is the motivation behind this paper. In the circuit structure of this filter with only one active device with a minimal number of transistors and five passive components are being used. Non ideal effects of the design are investigated and simulation results of the application, using TSMC 0.25 μm process parameters with ±1.25 V power supply voltage and the bias as 0.8 V resulting in 0.99 mW power dissipation for the entire filter, are also presented to confirm the theoretical analysis. With this new design technique, the tunabilities of the angular frequency ( ) and quality factor ( ) can be performed independently.
Proficient link state routing in mobile ad hoc network‐based deep Q‐learning network optimized with chaotic bat swarm optimization algorithm
Authors: Rahul P. , Kaarthick B. 
Published: November 2022

SummaryMobile ad‐hoc network (MANET) is a category of ad‐hoc network that can be reconfigurable its network. MANETS are self‐organized networks, that can use the wireless links to connect various networks via mobile nodes: but it consumes more energy and it also has routing problems. This is the major drawback of being connected with the MANET technology. Therefore, this study proposes a new protocol as deep Q‐learning network optimized with chaotic bat swarm optimization algorithm (CBS)‐based optimized link state routing (OLSR) (CBS‐OLSR) for MANET. This protocol reduces MANET energy usage and adopts OLSR multi‐point relay (MPR) technology. MANET's OLSR and the CBS algorithm utilize a similar method to locate the best optimum path from source to destination node. By embedding the new improved deep Q‐learning and OLSR algorithms, both are used for optimizing the MPR sets selection, it can efficiently diminish the energy consumption in the network topology, but automatically increase the lifespan of the network. It also enhances the package delivery ratio and decreases end‐to‐end delay. The experimental outcomes prove that the proposed protocol is reliable and proficient that is appropriate for numerous MANET applications.
Sexual imprinting leads to speciation in locally adapted populations
Authors: Sibly Richard M. , Curnow Robert N. 
Published: November 2022

AbstractSexual imprinting is widespread in birds and other species but its existence requires explanation. Our results suggest that sexual imprinting leads to speciation in locally‐adapted populations if a neutral mating cue—e.g., novel plumage coloration—arises through mutation. Importantly, the mating cue locus is not linked to adaptation loci. Local adaptation is a necessary precursor to speciation and occurs when evolution results in stable genetic polymorphisms with one allele predominating in some areas while others predominate elsewhere. Here we use a deterministic two‐niche population genetic model to map the set of migration and selection rates for which polymorphic evolutionary outcomes, i.e., local adaptations, can occur. Approximate equations for the boundaries of the set of polymorphic evolutionary outcomes were derived by Bulmer (American Naturalist, 106, 254, 1972), but our results, obtained by deterministic simulation of the evolutionary process, show that one of Bulmer's equations is inaccurate except when the level of dominance is 0.5, and fails if one of the alleles is dominant. Having an accurate map of the set of migration and selection rates for which polymorphic evolutionary outcomes can occur, we then show using the model of Sibly et al. (Ecology and Evolution, 9, 13506, 2019) that local adaptation in all analyzed cases leads to speciation if a new neutral mating cue arises by mutation. We finish by considering how genome sequencing makes possible testing our model and its predictions.

AbstractGrotta Mora Cavorso (Jenne, Latium), a complex karstic system in Central Italy, has returned one of the most precious Prehistoric palaeontological and anthropological heritage. Through the analysis of pollen spectra and charcoals from cave stratigraphic levels (Late Pleistocene final phases—Holocene), the overall vegetation trend of the site was pointed out. Although taphonomy and palynology of cave deposits are complex, pollen assemblage represents a reliable source for inferring past vegetation; indeed, climatic, environmental, and cultural interactions determine fossil pollen record. Site formation processes and postdepositional bias should be generally considered in the analysis of stratigraphic sequences used to define paleoenvironmental conditions. The sediment deposits from Grotta Mora Cavorso showed a vegetation pattern point in out a progressive increase in woody plants from lower levels upward. Palynological investigations highlighted a changing environment predominantly characterized by cooler and perhaps more humid conditions than today, with plant subalpine and marsh communities nearby the cave. The ecological requirements of the identified plant taxa supplied useful indications to reconstruct ancient and modern environments of the Simbruini Mounts and the Upper Aniene River valley. This scenario, in accordance with previous faunistic and carpological findings and palynological analyses from Latium, provided a further perspective on the vegetation history, biodiversity, and climate of an important crossroads between the Adriatic and the Tyrrhenian coasts.

AbstractPopulations of green turtles (Chelonia mydas), a megaherbivore that consumes seagrasses via cultivation grazing, are recovering worldwide. Information on plant‐mediated effects on herbivore foraging behavior is critical to understanding plant–herbivore interactions and sustainability of grazing as ecosystems continue to change. In a Caribbean seagrass ecosystem, we use stationary cameras and benthic surveys to evaluate the effects of seagrass morphology and leaf nitrogen content on green turtle grazing behavior.Thalassia testudinumleaf morphology has significant effects on forage intake (in milligrams of dry mass [DM] per minute) for green turtles, whereas leaf nitrogen content has no effect. Intake increases in grazed areas with shorter leaves and higher leaf biomass concentration (in milligrams of DM per cubic centimeter), indicating more efficient foraging under these conditions. Bite rate (in bites per minute) increases in grazed areas with short leaves, a result of reduced search time. Bite size (in milligrams of DM per bite) increases in grazed areas with short but dense canopies, because a turtle crops more shoots with each bite. Increased foraging efficiency and reduced search time in grazed areas with high biomass concentrations collectively maximize intake. Ingested leaves are shorter than the mean height of all available leaves in grazed areas, indicating herbivore selection for shorter leaves. Our estimate for daily intake is 86.1 g DM day−133‐kg turtle−1. Our study provides a novel contribution on the effects of plant‐level cues on the grazing behavior of a marine megaherbivore, and how cultivation grazing behavior optimizes the green turtle foraging strategy by maximizing foraging efficiency and intake.

Published: November 2022

AbstractAccording to the Food and Agricultural Policy Research Institute, the demand for edible oils and fats is growing. Tucumã is a native Amazonian fruit with high lipids content in the pulp and kernel. The pulp oil has a high content of unsaturated fatty acids and carotenoids, mainly β‐carotene, a pro‐vitamin A. Kernel fat has high oxidative stability as it is rich in saturated fatty acids, with a predominance of lauric acid. Tucumã pulp oil and kernel fat can formulate functional fats due to their physicochemical, nutritional, and sensory properties. This paper aims to provide an overview of intellectual property and academic production about tucumã oil and fat. The increase in scientific production from 2001 to 2020 indicates that the research institutes have expanded interest in tucumã fruit. However, intellectual property using tucumã oil and fat for industrial applications is still modest. Using the selected keyword combinations, nineteen and ten papers related to pulp oil and kernel fat are met, respectively. The United States leads the patents publications related to tucumã fruit, oil, and fat (45%). Most patents are directed to the cosmetic and pharmaceutical sectors (59%), demonstrating the necessity for studies focused on applications in the food industry.Practical Applications: Tucumã pulp oil and kernel fat can be used to formulate functional fats due to their physicochemical, nutritional, and sensory properties.

AbstractThere is a growing body of work suggesting that social class stereotypes are amplified when people perceive higher levels of economic inequality—that is, the wealthy are perceived as more competent and assertive and the poor as more incompetent and unassertive. The present study tested this prediction in 32 societies and also examines the role of wealth‐based categorization in explaining this relationship. We found that people who perceived higher economic inequality were indeed more likely to consider wealth as a meaningful basis for categorization. Unexpectedly, however, higher levels of perceived inequality were associated with perceiving the wealthy as less competent and assertive and the poor as more competent and assertive. Unpacking this further, exploratory analyses showed that the observed tendency to stereotype the wealthy negatively only emerged in societies with lower social mobility and democracy and higher corruption. This points to the importance of understanding how socio‐structural features that co‐occur with economic inequality may shape perceptions of the wealthy and the poor.

Published: November 2022

AbstractTimber buildings have been preferred in many regions for the sustainable nature of timber material. Although engineered timber products become promising alternates to traditional construction materials, the fire safety of timber buildings remains a key barrier to wider use. Currently, the design of timber structures mostly adopts the Eurocode 5 approach, which estimates the heat transfer or char depth under the premise of standard fire exposure. To investigate the behaviour of timber structural members in the context of realistic fire action in compartments, appropriate models for different stages of numerical simulation are needed. A series of development have now been conducted in the open‐source platform OpenSees, which enables modelling the heat transfer of timber sections in non‐standard fire scenarios and thermo‐mechanical analysis model using either beam elements or shell elements for various timber structural members. Corresponding thermal actions are developed to deal with timber slabs in fire or timber beams subjected to three‐side fire exposure. Tests on cross‐laminated timber beams at ambient temperature and under fire exposure are modelled to validate the developed capabilities, which is followed by modelling a glued laminated timber beam heated by furnace. In the end, a timber‐concrete composite slab is modelled using the fire impact from a Computational Fluid Dynamics model, which demonstrates the current vision of modelling timber structures in fire and OpenSees for fire is committed to providing such an open‐source research platform to support further modelling work.

Authors: Aberoumand Ali , Baesi Farideh 
Published: November 2022

AbstractThe Lethrinus lentjan fish is economically and nutritionally important in Iran. Therefore, knowledge of their chemical composition can help in the development of functional foods. In the present study, proximate and fatty acid compositions were determined in fresh and marinated Lethrinus lentjan fish. Fatty acids were identified by gas chromatography. The 24 pieces of fresh L. lentjan fish with an average weight of 470 ± 125 g were prepared. After removing wastes, the fish fillet was placed in a dish containing acetic acid, salt, garlic, and red pepper. The marinade product contained n‐6PUFA (7.94%) and n‐3PUFA (3.46%). The results showed that moisture content in the marinade sample decreased, while fat, protein, and ash contents increased and carbohydrate content was also decreased compared to the raw sample. The marinating process increased PUFA percentage (19.32%) and ratio of PUFA and SFA (0.61). The fresh and processed samples showed superior nutritional quality and the lowest h/H ratio, but AI and TI ratios were relatively favorable (p < .05). The thrombogenicity index (TI) (0.46) and atherogenicity index (AI) (3.56) were more than the recommended in terms of risk of coronary heart disease. It can be concluded that fresh and processed fish samples represent an excellent source of high‐quality fat, demonstrating that this fish species’ freshwater can be considered optimal for human consumption.

AbstractBackgroundTrifluoperazine (TFP) is a typical antipsychotic primarily used to treat schizophrenia. In this study, we aimed to evaluate whether TFP can be used as a therapeutic agent against nasopharyngeal carcinoma (NPC) and identify its underlying molecular mechanisms.MethodsWe used NPC‐TW01, TW03, TW04, and BM to assess the anticancer effects of TFP by using cytotoxicity, wound healing, colony formation, and cell invasion assays. An in vivo animal study was conducted. RNA sequencing combined with Ingenuity Pathways Analysis was performed to identify the mechanism by which TFP influences NPC cells.ResultsOur data revealed that TFP decreased NPC cell viability in a dose‐dependent manner. The invasion and migration of NPC tumor cells were inhibited by TFP. An in vivo study also demonstrated the anticancer effects of TFP. RNA sequencing revealed several anticancer molecular mechanisms following TFP administration.ConclusionsThe antipsychotic drug TFP could be a potential therapeutic regimen for NPC treatment.

AbstractThe article deals with the plasma‐assisted chemical vapor deposition of 0.3–1.4 μm thick a‐C:H:SiOx films in a mixture of argon and polyphenylmethylsiloxane vapor onto the Ti–6Al–4V alloy substrate, which is often used as an implant material. The a‐C:H:SiOx film structure is studied by the Fourier‐transform infrared and Raman spectroscopies. The pull‐off adhesion test assesses the adhesive strength of a‐C:H:SiOx films, and the ball‐on‐disk method is employed to measure their wear rate and friction coefficient. According to these studies, a‐C:H:SiOx films are highly adhesive to the Ti–6Al–4V substrate, have low (0.056) friction coefficient and wear rate (9.8 × 10−8 mm3 N−1 m−1) in phosphate‐buffered saline at 40°C. In vitro studies show neither thrombogenicity nor cytotoxicity of the a‐C:H:SiOx film for the human blood mononuclear cells (hBMNCs). The in vitro contact between the hBMNC culture and a‐C:H:SiOx films 0.8–1.4 μm thick deposited onto Ti–6Al–4V substrates reduces a 24‐hour secretion of pro‐inflammatory cytokines and chemokines IL‐8, IL‐17, TNFα, RANTES, and MCP‐1. This reduction is more significant when the film thickness is 1.4 μm and implies its potential anti‐inflammatory effect and possible application in cardiovascular surgery. The dependence is suggested for the concentration of anti‐inflammatory cytokines and chemokines and the a‐C:H:SiOx film thickness, which correlates with the surface wettability and electrostatic potential. The article discusses the possible applications of the anti‐inflammatory effect and low thrombogenicity of a‐C:H:SiOx films in cardiovascular surgery.
The making of hypervirulent Klebsiella pneumoniae
Authors: Dai Piaopiao , Hu Dakang 
Published: November 2022

AbstractKlebsiella pneumoniae is a notorious bacterium in clinical practice. Virulence, carbapenem‐resistance and their convergence among K. pneumoniae are extensively discussed in this article. Hypervirulent K. pneumoniae (HvKP) has spread from the Asian Pacific Rim to the world, inducing various invasive infections, such as pyogenic liver abscess, endophthalmitis, and meningitis. Furthermore, HvKP has acquired more and more drug resistance. Among multidrug‐resistant HvKP, hypervirulent carbapenem‐resistant K. pneumoniae (Hv‐CRKP), and carbapenem‐resistant hypervirulent K. pneumoniae (CR‐HvKP) are both devastating for their extreme drug resistance and virulence. The hypervirulence of HvKP is primarily attributed to hypercapsule, macromolecular exopolysaccharides, or excessive siderophores, although it has many other factors, for example, lipopolysaccharides, fimbriae, and porins. In contrast with classical determination of HvKP, that is, animal lethality test, molecular determination could be an optional and practical method after improvement. HvKP, including Hv‐CRKP and CR‐HvKP, has been progressing. R‐M and CRISPR‐Cas systems may play pivotal roles in such evolutions. Hv‐CRKP and CR‐HvKP, in particular the former, should be of severe concern due to their being more and more prevalent.
Community experiences in the strategic human resource management black box

Published: November 2022

AbstractRecent research suggests experiencing community at work (i.e., perceiving a sense of community [SOC] and a sense of community responsibility [SOC‐R]) is important for employee and organizational outcomes, however, we know very little about how these constructs operate in human resource management contexts. This study peers into the strategic human resource management “black box,” which is an organizational setting where psychological and social variables are believed to influence employee perceptions in ways that impact their individual functioning, and subsequently improve organizational outcomes. Specifically, the study tests hypotheses regarding the relationship between high‐involvement work climate (i.e., a human resource context), psychological need satisfaction, SOC, SOC‐R, organizational identification, and organizational citizenship behaviors, in an attempt to theoretically ground, and empirically test, if experiences of community matter in the human resource management “black box.” Data from 312 employees across multiple organizations were analyzed using partial least squares structural equation modeling, and the findings reveal that experiences of community likely play an important role in the strategic human resource black box. The findings highlight that human resource practitioners, and scholars at the intersection of community psychology and human resource management, should consider further evaluation and action around experiences of community at work. Such a focus may help to create and build more socially sustainable organizational contexts for employees where they can thrive while organizations attempt to achieve collective goals.
