Abstract
This article is devoted to the experimental study of the temperature regimes of the solar pond in the southern climatic conditions of Uzbekistan. The research was conducted in an experimental version of a solar pond that accumulates low-potential heat. According to research, when taking heat from a salt solar pond, without a coating on its upper surface and comparing the results of a glass-covered experiment is 10-15% higher than that of a glass-covered experiment, when the ambient temperature is 34 °C and solar radiation is 973 W/m2 it is scientifically based that the temperature of saline solar pond water with a concentration of 25-30% rises to a temperature of 53 °C in the lower part of the pond and that the energy storage efficiency of the lower convective zone of the solar pond increases in parallel with increasing solar radiation

Abstract
Woven abaca fiber also known as “Sinamay” was usually used in textile and handcraft industries. In this paper, the use of woven abaca fiber was utilized as a potential component in a fiber reinforced polymer (FRP) composite material. It also aims to study the effects of increasing abaca fiber layer on the mechanical and water absorption properties of the composite. The composite laminates having 1, 3, 5, and 7 layers of woven abaca stacked in between of glass fiber mats: plain-woven fabric and chopped strand and polyester resin as binder were fabricated by hand lay-up technique. These abaca-glass fiber reinforced polyester composite specimens were characterized using tensile test, flexural test, izod impact test, and water absorption test. Upon introducing and increasing the amount of abaca layers in the composite, the results showed that its properties were significantly changed. The mechanical strength was decreased while water absorbed was increased as the amount of abaca layer increases.

Abstract
Pure agar (PA)-based resistive random access memory (RRAM) devices using simple solution process method were demonstrated. The memory properties of the investigated PA-based resistive layers are determined by the relationship between the physical properties of the PA thin films and the RRAM performance. The memory properties of PA films with 2 different bottom substrates (glass and PET) and ITO as bottom electrodes were also investigated to explore the differences between rigid and flexible substrates. The RRAM fabricated from PA film and PET substrates exhibit good uniformity acceptable retention over 104 s, and high ON/OFF ratio (>104) at room temperature. According to the fitting results, the RRAM made of PA thin film conforms to the Space-charge-limited current model. This work helps to understand the resistive switching and maintain stable operations of Agar-based RRAM, which means a lot for increasing the application of agar in flexible devices.
Defect-doped one-dimensional nonlinear photonic crystals exhibit coherent perfect absorption with bistable properties
Authors: Xing Feng-Ge , Zhang Dan , Zhang Hai-Feng 
Published: August 2022

Abstract
In this paper, the bistable phenomenon with the coherent perfect absorption properties are studied through the nonlinear transfer matrix method in one-dimensional nonlinear photonic crystals doped with a defect. The focus is on the influences of the relative phase of coherent light on the bistable coherent absorption intensity, and the tuning of the bistable threshold by parameters such as angle and wavelength of incidence. The simulated results show that the coherent absorption intensity is very sensitive to the relative phase of coherent incidence. As the phase decreases, the absorption intensity also decreases, varying from 1 to −1 when the phase change is within 180°. The tuning of the relative phase to the absorption intensity provides great convenience for the application of bistable, and parameters such as the incident angle can also achieve sensitive tuning of the bistable threshold. The larger the incident angle, the larger the threshold, and the more obvious the bistable phenomenon at TE mode. The application of nonlinear optical devices has been expanded in the fields of filters, optical switches, optical power threshold devices, etc.
Preparation of high wear resistance nickel based WC coating by carefully adjusting interface structure

Abstract
In recent years, many scholars have paid attention to wear-resistant coatings for shield machine cutterheads due to their very high consumption rates. Among these coatings, nickel-based tungsten carbide (Ni-based WC) is one of the best, showing both corrosion resistance and wear resistance. However, to further improve the wear resistance of such coatings, there are still numerous issues that need to be resolved. Herein, a new method, distinct from conventional methods, is presented. Specifically, the brittle phase W2C is not widely regarded as the main wear-resistant phase, but we were surprised to find that careful adjustment of its rigid structure can yield satisfactory results. Experimental results and first-principles simulations have indicated that the friction coefficient and weight loss of a coating with a suitable distribution of W2C are only half of those of a traditional Ni-based WC coating (about five times higher than those of the substrate), which can mainly be attributed to the excellent thermal expansion coefficient and hardness of the W2C phase. As we expected, the surface morphology of the material after wear revealed that the suitable W2C layer has a well-defined friction morphology. We hope to provide new ideas for the study of Ni-based WC coatings in shield machine cutterheads.

Interplay between conservatism and divergence in climatic niche evolution of Brassicaceae tribe Eudemeae shaped their distribution across the different environments of the Andes
Authors: Salariato Diego L , Trinidad Huber , Cano Asunción , Zuloaga Fernando O , Al-Shehbaz Ihsan A 
Published: August 2022

Abstract
The Andean region is one of the most biodiverse areas, displaying high levels of endemism and spatial turnover of species. Tribe Eudemeae includes nine genera and 40 species distributed from the northern Andes in Colombia to the southernmost portion of the Andes in Argentina and Chile. Here, we generated a species-level phylogenetic tree to study their climatic niche evolution. We first analysed phylogenetic structure and evolutionary shifts among the main climatic spaces using model-based estimates. Second, we estimated climatic niches for each species and compared them in a phylogenetic context. In Eudemeae, three main groups of climatic spaces were found, mainly related to the northern and central Andes, the north-central portion of the southern Andes and the central-southern portion of the southern Andes. Results suggest that initial colonization of new climatic spaces in the evolution of the tribe appears to be promoted through shifts in adaptive regimes, whereas subsequent diversification of genera occurred predominantly under the same climatic regimes. This trade-off between niche conservatism and divergence appears to have modulated their diversification across the Andes and contributed to their current geographical distribution.

Abstract

Background
Sweat glands (SGs) have low regenerative potential after severe burns or trauma and their regeneration or functional recovery still faces many obstacles. In practice, restoring SG function requires not only the structural integrity of the gland itself, but also its neighboring tissues, especially blood vessels. Collagen triple helix repeat containing-1 (CTHRC1) was first identified in vascular repair, and increasing reports showed a close correlation between cutaneous appendage specification, patterning and regeneration. The purpose of the present study was to clarify the role of CTHRC1 in SGs and their adjacent microvessels and find therapeutic strategies to restore SG function.

Methods
The SGs and their adjacent microvascular network of Cthrc1−/− mice were first investigated using sweat test, laser Doppler imaging, tissue clearing technique and transcriptome analysis. The effects of CTHRC1 on dermal microvascular endothelial cells (DMECs) were further explored with cell proliferation, DiI-labeled acetylated low-density lipoprotein uptake, tube formation and intercellular junction establishment assays. The effects of CTHRC1 on SG function restoration were finally confirmed by replenishing the protein into the paws of Cthrc1−/− mice.

Results
CTHRC1 is a key regulator of SG function in mice. At the tissue level, Cthrc1 deletion resulted in the disorder and reduction of the microvascular network around SGs. At the molecular level, the knockout of Cthrc1 reduced the expression of vascular development genes and functional proteins in the dermal tissues. Furthermore, CTHRC1 administration considerably enhanced SG function by inducing adjacent vascular network reconstruction.

Conclusions
CTHRC1 promotes the development, morphogenesis and function execution of SGs and their neighboring vasculature. Our study provides a novel target for the restoration or regeneration of SG function in vivo.

Abstract
A common approach to estimate the strength and direction of selection acting on protein coding sequences is to calculate the dN/dS ratio. The method to calculate dN/dS has been widely used by many researchers and many critical reviews have been made on its application after the proposition by Nei and Gojobori in 1986. However, the method is still evolving considering the non-uniform substitution rates and pretermination codons. In our study of SNPs in 586 genes across 156 Escherichia coli strains, synonymous polymorphism in 2-fold degenerate codons were higher in comparison to that in 4-fold degenerate codons, which could be attributed to the difference between transition (Ti) and transversion (Tv) substitution rates where the average rate of a transition is four times more than that of a transversion in general. We considered both the Ti/Tv ratio, and nonsense mutation in pretermination codons, to improve estimates of synonymous (S) and non-synonymous (NS) sites. The accuracy of estimating dN/dS has been improved by considering the Ti/Tv ratio and nonsense substitutions in pretermination codons. We showed that applying the modified approach based on Ti/Tv ratio and pretermination codons results in higher values of dN/dS in 29 common genes of equal reading-frames between E. coli and Salmonella enterica. This study emphasizes the robustness of amino acid composition with varying codon degeneracy, as well as the pretermination codons when calculating dN/dS values.
Political Competition and State Capacity: Evidence from a Land Allocation Program in Mexico
Authors: Fergusson Leopoldo , Larreguy Horacio , Riaño Juan Felipe 
Published: August 2022

Abstract
We develop a model of the politics of state capacity building undertaken by incumbent parties that have a comparative advantage in clientelism rather than in public goods provision. The model predicts that, when challenged by opponents, clientelistic incumbents have the incentive to prevent investments in state capacity. We provide empirical support for the model’s implications by studying policy decisions by the Institutional Revolutionary Party that affected local state capacity across Mexican municipalities and over time. Our difference-in-differences and instrumental variable identification strategies exploit a national shock that threatened the Mexican government’s hegemony in the early 1960s.

Published: August 2022

Summary

The retrograde valve-crossing of a stenotic aortic valve is a crucial step in the transcatheter aortic valve implantation procedure. In addition to being time-consuming and associated with an increased stroke risk, inappropriate valve-crossing may cause devastating complications. This tutorial review summarizes systematic and detailed techniques to cross the aortic valve. First, the main challenges in retrograde valve-crossing are depicted. Next, a step-by-step guidance on valve-crossing is provided, along with an in-depth description of the three-dimensional anatomy under a two-dimensional fluoroscopy view. Finally, modified techniques for different anatomies are described.
International Law and the Rage against Scienticism
Authors: d’Aspremont Jean 
Published: August 2022

Abstract
In international legal thought and practice, anything that is related to the real or is grounded in the real is given discursive primacy. This discursive primacy is the manifestation of a common scientistic hierarchy of discourses inherited from Modernity that accords primacy to discourses about the real and grounded in the real. Anne Orford’s International Law and the Politics of History can be read as yet another expression of discontent with such primacy of the real and its scientistic methods. With an emphasis on international lawyers’ engagements with history, Orford specifically takes issue with the use of contextualist and empirical methods in the study of the history of international law. And, yet, as is argued in this review essay, scienticism leaves no way out for those seeking to contest it: Orford’s charge against contextualism and empiricism itself needs to be contextualized and empirically supported.
Challenge of a therapeutic sequence: rare case of heart failure in mitral valvular disease intensified by an extreme mediastinal shift from major diaphragmatic eventration

Published: August 2022

Abstract
Extreme mediastinal shift due to major diaphragm eventration is complex when mitral-valve repair is required. We report the case of a 59-year-old woman with diaphragmatic eventration who had 2 recent episodes of heart failure due to arrythmia associated with severe mitral-valve regurgitation (regurgitant orifice area 47 mm2). Forced expiratory flow-volume in the first second and vital capacity (VC) were at 32% and 33%, respectively,decreasing to 20% and 30% when she was in a supine position. We found it impossible to repair the valve first because of the extreme mediastinal shift and respiratory dysfunction. Therefore, we decided to perform diaphragm plication first followed 3 months later by mitral valve repair. Six months after the cardiac operation, the patient showed significant clinical improvement. Forced expiratory flow-volume in the first second and vital capacity increased to 58% and 55%, respectively. The decision to perform the thoracic operation first, followed by the cardiac operation, was the key to improving the patient’s respiratory function and to medializing the heart to safely support cardiac surgery.

AbstractMonitoring cardiovascular and respiratory measurements corresponds to the precision livestock farming (PLF) objective to continuously monitor and assess dairy cows’ welfare and health. Changes in heart rate, breathing rate, and oxygen saturation (SpO2) are valuable metrics in human and veterinary medicine to assess stress, pain, illness, and detect critical conditions. The common way to measure heart rate is either manually or with a stethoscope. Under research conditions, heart rate is usually measured with a sports watch chest belt. Breathing rate is obtained by counting the cow’s flank movements which is a time-consuming and labor-intensive method that requires training and is prone to human error. No devices are available on the market that enable practical and easy pulse oximetry in farm animals. This study presents a wireless nose ring sensor system (NoRS) composed of thermal and photoplothysmography sensors that attach to the nostrils of four Holstein dairy cows. The NoRS’s thermocouple measured the cow’s nasal cavity air temperature; an optic sensor measured the IR (660 nm) and RED (660 nm) signals reflected from the cow’s nasal septum. Breathing was calculated from the thermocouple signal’s center frequency with a fast Fourier transformation or the signal peak count (i.e., oscillations). The breathing rate was compared to breathing observed by concurrently counting the flank movements. Heart rate and SpO2 were measured by integrated pulse oximetry and heart rate monitor module (MAX30101 TinyCircuit) assembled on the NoRS circuit. Heart rate was also measured with FFT and by counting the number of peaks from the optic sensor’s raw IR and RED signals. These measures were compared to an off-the-shelf hand-held pulse oximeter’s heart rate and SpO2 readings during the same time. The comparisons revealed highly significant correlations for the heart rate readings where the strength of the correlation was sensitive to the method. The correlation between breathing rate and the veterinarian’s visual observations was low, albeit significant. Thus, inhale-exhale cycle counting constitutes a more precise approach than flank movement counts. The hand-held device’s 96% SpO2 is compatible with near-saturation values expected in healthy cows. The mean NoRS SpO2 reading was 3% less. After further piloting under field conditions, the NoRS will require no animal restraining to automatically and continuously record cows’ breathing rate, heart rate, and SpO2.
Necrophilia, Psychiatry, and Sexology: The Making of Sexual Science in Mid-Twentieth Century Peru
Authors: Drinot Paulo 
Published: August 2022

Abstract
In this article, I draw on two sets of sources to explore how Peruvian doctors tried to make sense of what had driven a man to engage in necrophilia in late 1942. On the one hand, I examine the case history and other related documentation that I located in Lima’s psychiatric hospital. On the other, I study a detailed article written on the case by Dr Lucio D. Castro and published in 1943. Together, these sources provide rich evidence on how Peruvian doctors addressed what they framed as an abnormality of the sexual instinct and, in turn, as a mental disorder. But the case also provides a fascinating vista on a major taboo—sex with the dead—and more generally on the history of “perversion” and therefore on the history of sexuality in Peru. I pay particular attention to how doctors mobilized an eclectic “theoretical artillery” of biomedical knowledge in trying to explain the man’s psychopathology. I argue that through their “unruly appropriation” of sexological knowledge, doctors like Castro sought to make meaningful contributions to a global sexual science while proposing means to channel sexuality away from deviant forms in a manner consonant with broader projects of sexual regulation that Peru and other countries promoted at the time.
Diagnostic Uncertainty in Cervical Radiculopathy
Authors: George Douglas , Campbell Leonie , Marra Janelle 
Published: August 2022

ABSTRACT
Cervical radiculopathy is defined as a pathological process affecting the cervical nerve root(s). While not an uncommon entity, this report describes a case of cervical radiculopathy in an active duty Marine with unique features to include the C5 nerve root as the primary point of injury with corresponding severe motor weakness that warranted expedited workup. This expedited workup included early referral to Neurology for nerve conduction and electromyography (EMG) studies that were ultimately diagnostic in the setting of equivocal Magnetic Resonance Imaging findings. This highlight of this case is the demonstration of the utility of EMG in cervical radiculopathy evaluation, which aided in an efficient and effective treatment course. We contend that in cases of cervical radiculopathy with a focal deficit of profound weakness with shoulder abduction and elbow flexion, obtaining nerve conduction studies and EMGs within the first 4 to 6 weeks of presentation should be viewed as essential for the long-term recovery and effective management of the injured service member, particularly when injury to the upper trunk of the brachial plexus can also account for these specific motor deficits. This report will cover a brief review of the pathophysiology, evaluation, and natural history of cervical radiculopathy with special attention paid to the timing and efficacy of EMG.
