Published: November 2023

SummaryMany monitoring applications related to surveillance, tracking and multipurpose visual monitoring have taken into consideration the use of wireless visual sensor networks. When sensors are deployed over a monitored field that could potentially damage the monitoring capability and availability in the visual sensor network. In order to overcome these issues, faulty nodes are identified and replaced by redundant node based on Siamese network in this research. Initially, camera nodes are randomly deployed in the visual sensor network, and the data are received from the network through gateway. To identify the redundant nodes, initially, the frames are divided into equivalent time slot, and then, Siamese network is utilized to identify the redundant nodes in a network. Siamese neural network is type of convolutional neural network that is utilized to recognize the similar images in the network. After that, faulty nodes are identified based on some parameters such as entropy, energy, transmission delay and network coverage. If the average energy, entropy, transmission delay and network coverage are below the threshold value, then the node is identified as faulty node. Finally, replace the faulty node with redundant node to enhance the availability in the visual sensor network for critical monitoring applications. The simulation analysis shows that the developed approach takes 772 s to identify redundant node and take 27 s to identify fake nodes and the developed method is executed at 1308 s. Thus, this prediction model helps to improve the coverage quality of target‐based monitoring in order to achieve availability.

Published: November 2023

AbstractCities can have profound impacts on ecosystems, yet our understanding of these impacts is currently limited. First, the effects of the socioeconomic dimensions of human society are often overlooked. Second, correlative analyses are common, limiting our causal understanding of mechanisms. Third, most research has focused on terrestrial systems, ignoring aquatic systems that also provide important ecosystem services. Here we compare the effects of human population density and low‐income prevalence on the macroinvertebrate communities and ecosystem processes within water‐filled artificial tree holes. We hypothesized that these human demographic variables would affect tree holes in different ways via changes in temperature, water nutrients, and the local tree hole environment. We recruited community scientists across Greater Vancouver (Canada) to provide host trees and tend 50 tree holes over 14 weeks of colonization. We quantified tree hole ecosystems in terms of aquatic invertebrates, litter decomposition, and chlorophyll a (chl a). We compiled potential explanatory variables from field measurements, satellite images, or census databases. Using structural equation models, we showed that invertebrate abundance was affected by low‐income prevalence but not human population density. This was driven by cosmopolitan species of Ceratopogonidae (Diptera) with known associations to anthropogenic containers. Invertebrate diversity and abundance were also affected by environmental factors, such as temperature, elevation, water nutrients, litter quantity, and exposure. By contrast, invertebrate biomass, chl a, and litter decomposition were not affected by any measured variables. In summary, this study shows that some urban ecosystems can be largely unaffected by human population density. Our study also demonstrates the potential of using artificial tree holes as a standardized, replicated habitat for studying urbanization. Finally, by combining community science and urban ecology, we were able to involve our local community in this pandemic research pivot.

AbstractTerrestrial arthropods are a diverse taxonomic group of significant ecological and economic importance. Our ability to understand the diversity that comprises this group is hampered by the variety of sampling techniques and high level of taxonomic expertise required to identify individual species. DNA metabarcoding approaches have potential to overcome these challenges but have been mainly limited to studies where DNA is directly extracted from trapped individuals. We posit that collection of environmental DNA (eDNA) deposited on vegetation surfaces could provide an alternative method of conducting metabarcoding‐based arthropod inventories. In this study, we illustrate the promise of characterizing arthropod biodiversity based on eDNA collected from terrestrial plant surfaces. We collected 40 paired samples using two novel eDNA sampling techniques—tree bark and foliage sampling—in a New Jersey, USA, pine barrens forest. Metabarcoding using two primer sets revealed significantly higher taxonomic richness for the 16S versus COI primer set (1077 vs. 650 molecular operational taxonomic units; MOTUs), as well as higher richness and diversity in foliage versus bark samples. Accumulation curves suggest that our samples captured about half of the available MOTU‐level diversity. Matching to reference databases revealed 28 arthropod orders, 181 families, 353 genera, and 292 species. Despite having lower MOTU‐level richness, the COI primer set revealed more taxa that were identified to species (197 vs. 115) and genus (227 vs. 173) thanks to a more complete reference database. The two primer sets and sampling substrates showed distinct community compositions that differed in important ecological traits (feeding guild, body size), demonstrating the utility of a multi‐faceted sampling and analytical approach. Our study highlights the value of exploiting eDNA left on plant surfaces via metabarcoding for contributing to rapid arthropod inventories, and thus realizing a range of ecological research and management goals.
Accountability in the environmental crisis: From microsocial practices to moral orders
Authors: Lidskog Rolf , Standring Adam 
Published: November 2023

AbstractThe global environmental crisis is the result of a complex web of causation and distributed agency, where not even the most powerful individual actors can be considered responsible nor remedy the situation alone. This has prompted multiple calls across societies for transformative social change. What role can accountability play in this context? Starting in the theoretical traditions of microsociology and pragmatic sociology, this article elaborates the role of accountability in social interactions. To provide an account that justifies an action or inaction is here understood as a process of social ordering, where accounts are assessed as acceptable only after they have been tested against higher normative principles. Microsocial practices are, in this way, linked to macrosocial order. The following section turns to the global environmental crisis, showing that the crisis raises normative as well as epistemic challenges. The complexity of the socio‐environmental situation makes it hard to know what should be done and opens normative orders and epistemic claims to contestation. This situation provides increased opportunities for strategic maneuvering to justify actions as well as opportunities to question social practices and social order. The article concludes by discussing the role of accountability in climate change. Accountability can serve as a mechanism to attach issues to the current environmental crisis and re‐embed decisions and practice in an environmental moral order. As part of a broader palette of instruments, rules and norms, accountability has an important function to play in transforming society towards sustainability.

Published: November 2023

Abstract2‐Hydroxypyridines have emerged as versatile nucleophiles in organic synthesis. The N‐ and O‐functionalization of 2‐hydroxypyridines affords straightforward and practical methods for the construction of N‐substituted 2‐pyridones and O‐substituted 2‐hydroxypyridines, which are important structural motifs in numerous natural products, pharmaceuticals and biologically active compounds. Nonetheless, the competition between N‐ and O‐functionalization of 2‐hydroxypyridines presents an inevitable and formidable challenge. In the past few decades, chemoselective N‐ and/or O‐functionalization of 2‐hydroxypyridines has received extensive attention from the synthetic community, resulting in the development of elegant and effective strategies to address this chemoselectivity. This review provides a summary of recent advancements in the realm of transition‐metal and organo‐catalyzed, as well as visible‐light promoted chemoselective functionalization of 2‐hydroxypyridines, including N‐alkylation, N‐allylation, N‐arylation, N‐alkenylation, O‐alkylation, O‐allylation, O‐arylation, and O‐alkenylation.
Dynamic analysis and optimization of snatch lift based on barbell trajectory and on an anthropometric model comprised of six links
Authors: Jon Min Hyok , Rim Un‐Ryong 
Published: November 2023

AbstractWeightlifting requires explosive strength, high speed, and flexibility. The aim of this research is to present a method based on barbell trajectory and on an anthropometric model comprised of six links for dynamic analysis and optimization of snatch lift. First, snatch lift is divided into nine stages based on barbell trajectory, velocity, and acceleration, while evaluating dynamic characteristics. Then, an anthropometric model of weightlifter which is comprised of six segments: shin, thigh, trunk, upper arm, forearm, and head is developed. Since the head accounts for more or less than 10% of body weight, it should be considered as one link of one degree of freedom. Physical properties such as mass and center of mass of each link are not given by statistical data, but by anthropometry and calculation in Solidworks program. Finally, for barbell trajectory as one of the most important performance indices in weightlifting, an optimal control problem is formulated to minimize a criterion function defined as the sum of work done by lifter during snatch lift and solved by using Pontryagin Maximum Principle (PMP). The proposed method is illustrated with case study, showing results in good agreement with ones by analysis of lifter's actual performances. It can help coach or weightlifter to improve the snatch technique.

Published: November 2023

AbstractA four‐stage CMOS operational amplifier is proposed in this work. The designed amplifier is frequency compensated via two differential blocks and two Miller capacitors. Unlike well‐known frequency compensation methods, the proposed compensation leaves the output node while exploiting extremely smaller capacitors compared to conventional approaches. The presented approach is modeled symbolically and realized at the circuit level via the Hspice circuit simulator and 0.18 μm CMOS technology. Good agreements between two separate simulation paths verify the validity and accuracy of the proposed approach. Ample simulation results are reported to investigate the proposed amplifier regarding parameter mismatches. According to the simulation results, the proposed four‐stage amplifier is an excellent candidate to be used in larger systems such as data converters, modulators, and sensors while it shows more than 169 dB as DC‐gain, 10 MHz as unity gain frequency with power consumption less than 500 μW.

Published: November 2023

AbstractObjectiveNeurostimulation is an emerging treatment for patients with drug‐resistant epilepsy, which is used to suppress, prevent, and terminate seizure activity. Unfortunately, after implantation and despite best clinical practice, most patients continue to have persistent seizures even after years of empirical optimization. The objective of this study is to determine optimal spatial and amplitude properties of neurostimulation in inhibiting epileptiform activity in an acute hippocampal seizure model.MethodsWe performed high‐throughput testing of high‐frequency focal brain stimulation in the acute intrahippocampal kainic acid mouse model of status epilepticus. We evaluated combinations of six anatomic targets and three stimulus amplitudes.ResultsWe found that the spike‐suppressive effects of high‐frequency neurostimulation are highly dependent on the stimulation amplitude and location, with higher amplitude stimulation being significantly more effective. Epileptiform spiking activity was significantly reduced with ipsilateral 250 μA stimulation of the CA1 and CA3 hippocampal regions with 21.5% and 22.2% reductions, respectively. In contrast, we found that spiking frequency and amplitude significantly increased with stimulation of the ventral hippocampal commissure. We further found spatial differences with broader effects from CA1 versus CA3 stimulation.SignificanceThese findings demonstrate that the effects of therapeutic neurostimulation in an acute hippocampal seizure model are highly dependent on the location of stimulation and stimulus amplitude. We provide a platform to optimize the anti‐seizure effects of neurostimulation, and demonstrate that an exploration of the large electrical parameter and location space can improve current modalities for treating epilepsy.Plain Language SummaryIn this study, we tested how electrical pulses in the brain can help control seizures in mice. We found that the electrode's placement and the stimulation amplitude had a large effect on outcomes. Some brain regions, notably nearby CA1 and CA3, responded positively with reduced seizure‐like activities, while others showed increased activity. These findings emphasize that choosing the right spot for the electrode and adjusting the strength of electrical pulses are both crucial when considering neurostimulation treatments for epilepsy.
“An act of compassion”: Emotion and the struggle for reproductive justice
Authors: Torres Julie 
Published: November 2023

AbstractIn dialogue with the rich scholarship on affect and the role of emotions in feminist knowledge production, this article explores how compassion is mobilized by activists in the struggle for reproductive justice. The author centers emotional knowledge by drawing on conversations with a reproductive justice advocate in central Florida, the musical anthem of Viva Ruíz and the Thank God for Abortion Collective, and her own personal experience with pregnancy loss. This includes a discussion of the ways that coloniality persists in the racialized and gendered landscape of reproductive politics, with particular attention to the experiences of Puerto Ricans. Ultimately, the article argues that an attunement to “a radical compassion”—that is, a deep concern and understanding of the intersectional oppressions that place value on certain bodies over others—engenders the possibilities of reproductive justice and produces alternative ways of knowing and feeling.
A “hard question”: Gender affirming care and gender distress in a social world
Authors: Martin Paula 
Published: November 2023

AbstractGender affirming care for youth is currently under political attack across the United States. Critics of affirming care often leverage a biological and fixed notion of gender as assigned at birth, which is at odds with how gender has been theorized academically for decades. Yet for some feminist clinicians, the popularized version of SOCIAL CONSTRUCTION present within rhetoric about the purpose of affirmative intervention also seems to undercut the legitimacy of care. In this article, I track how the difficult problems of the origins of gender itself, problems seemingly exposed by the invocation of the SOCIAL CONSTRUCTION of gender, are managed within the field of gender affirming care. I show how by drawing on the narrative power of very young gender expansive people, and by orienting clinical care away from identity towards DISTRESS, medical providers can align themselves both with feminist desires to change how gender ideology functions in the social world, and with the need to provide interventions that allow youth to embody the gender they desire.
Semianalytical investigation on heat transfer in porous fins with temperature‐dependent thermal conductivity via the homotopy perturbation Sumudu transform approach

Published: November 2023

AbstractA unique investigation has been undertaken to analyze the heat transmission by convective and radiative mechanisms in a fully saturated penetrable fin of a longitudinal structure positioned on a leaning surface. This study introduces the fusion of the realms of Homotopy perturbation and Sumudu transform techniques to address a previously unexplored problem involving a moving fin with temperature‐dependent thermal conductivity. In prior research papers, the Homotopy Perturbation Sumudu Transform Method (HPSTM) was utilized to obtain analytical solutions for fins featuring temperature‐dependent thermal conductivity. However, in our current study, we employ the HPSTM to tackle a novel problem involving a moving porous fin. This fin exhibits temperature‐dependent thermal conductivity and is subjected to convection and radiation effects. Through a comparison with numerical results, the present study has validated the dependability of its findings. The dimensionless temperature profile has been investigated by studying its relationship with several parameters. Here we observed that when the Peclet number is augmented by 400%, there is a corresponding 1.11% increase in thermal outline at the fin's extremity. Enhancing the value of radiation parameter by 400% declines the temperature of the fin tip by 14.079%. This study encourages the application of the Homotopy perturbation Sumudu transform technique in more complex fin problems.

AbstractLung cancer is one of the most common cancers in men. Although many diagnostic and treatment regimens have been followed in the treatment for lung cancer, increasing mortality rate due to lung cancer is depressing and hence requires alternative plant based therapeutics with with less side‐effects. Myrtenol exhibits anti‐inflammatory and antioxidant properties. Hence we intended to study the effect of Myrtenol on B(a)P‐induced lung cancer. Our study showed that B(a)P lowered hematological count, decreased phagocyte and avidity indices, nitroblue tetrazolium (NBT) reduction, levels of immunoglubulins, antioxidant levels, whereas Myrtenol treatment restored them back to normal levels. On the other hand, xenobiotic and liver dysfunction marker enzymes and pro‐inflammatory cytokines were elevated on B(a)P exposure, which retuned back to normal by Myrtenol. This study thus describes the immunomodulatory and antioxidant effects of Myrtenol on B[a]P‐induced immune destruction.

AbstractBackgroundThrombosis is a common critical complication relating to radiofrequency catheter ablation and cryoablation. There is a possibility that high‐temperature stimulation during radiofrequency ablation or low‐temperature stimulation during cryoablation may affect the coagulability of blood. In this study, we aimed to determine the impacts of transient temperature stimulations on the coagulability of whole blood and to clarify if edoxaban suppressed the hypercoagulability.MethodsCitrated blood samples were drawn from 41 healthy subjects. Some blood samples were mixed with tissue factor (TF) and several concentrations of edoxaban (50, 100, and 200 ng/mL). Blood samples were exposed to several temperature stimulations for 1 min: heat stimulation (50°C) or cryostimulation (−20°C), and compared with control (37°C). Repeated cryostimulations or sequential cryo‐ and heat stimulation were also applied. Coagulability of whole blood was measured using a dielectric blood coagulometry. As an index of coagulability, the end of acceleration time (EAT) was used.ResultsBoth heat‐ and cryostimulations significantly shortened the EAT compared to the control, indicating that hypercoagulability was induced by temperature stimulations. Application of TF enhanced and extended the hypercoagulability after the temperature stimulations. Sequential application of cryo‐ followed by heat stimulation further enhanced the hypercoagulability of blood. Application of edoxaban increased the EAT in a concentration‐dependent manner in control condition. Edoxaban at 100 or 200 ng/mL completely suppressed the shortening of EAT evoked by these temperature stimulations.ConclusionTransient temperature stimulations evoked hypercoagulability regardless of cryo‐ or heat stimulation. Edoxaban with 100 ng/mL or more eliminated this temperature‐stimulated hypercoagulability.
