Effect of cutting management on the forage production and quality of tepary bean (Phaseolus acutifolius A. Gray)
Authors: Witt Travis W. , Northup Brian K. , Porch Timothy G. , Barrera Santos , Urrea Carlos A. 
Published: August 2023

AbstractTepary bean (Phaseolus acutifolius A. Gray) is an underutilized drought tolerant annual legume, originating from the Sonoran Desert, that may be a beneficial forage/hay for beef cattle in the Southern Great Plains of the US (SGP). The SGP has erratic rainfall and periods of intermittent drought exacerbated by high summer temperatures. In 2020 and 2021, a split-plot design was used to evaluate 13 genotypes of tepary bean and a forage soybean (control) at El Reno, OK, USA to compare production of plant biomass and forage nutritive value parameters under seven harvest regimes. Genotypes were used as the main plot and cutting management as the sub-plot. Biomass production of all tepary bean genotypes equaled that of soybean (p > 0.05), while several genotypes had superior forage nutritive value traits (p ≤ 0.05). Overall, a 15-cm cutting height and 30-day harvest interval produced the best overall product (average dry biomass of 5.8 Mg ha−1 with average relative feed values (RFV) of 165). Although all harvest regimes reduced total seasonal biomass, forage nutritive value increased. However, the tradeoff between forage production and nutritive value may be unacceptable to most producers. Further agronomic and breeding research is needed to encourage producers to grow tepary bean as a forage/hay in the SGP.
High optical spin-filtering in antiferromagnetic stanene nanoribbons induced by band bending and uniaxial strain
Authors: Rahimi F. , Phirouznia A. 
Published: August 2023

AbstractNon-equilibrium spin-polarized transport properties of antiferromagnetic stanene nanoribbons are theoretically studied under the combining effect of a normal electric field and linearly polarized irradiation based on the tight-binding model at room temperature. Due to the existence of spin-orbit coupling in stanene lattice, applying normal electric field leads to splitting of band degeneracy of spin-resolved energy levels in conduction and valence bands. Furthermore, unequivalent absorption of the polarized photons at two valleys which is attributed to an antiferromagnetic exchange field results in unequal spin-polarized photocurrent for spin-up and spin-down components. Interestingly, in the presence of band bending which has been induced by edge potentials, an allowable quantum efficiency occurs over a wider wavelength region of the incident light. It is especially important that the variation of an exchange magnetic field generates spin semi-conducting behavior in the bended band structure. Moreover, it is shown that optical spin-filtering effect is obtained under the simultaneous effect of uniaxial strain and narrow edge potential.
Taking a look accurately at the alteration of interfacial asphaltene film exposed to the ionic surfactants as demulsifiers

Published: August 2023

AbstractThe water droplets surrounded by a rigid interfacial asphaltene (ASP) film is one of the major setbacks in the petroleum industry. In this study, the properties of the interfacial ASP films around water droplets exposed to ionic surfactants as demulsifier were investigated. According to molecular dynamics (MD) simulation, the anionic surfactants are more effective than the cationic surfactant in the demulsification process since the anionic surfactants have the exact desire to localize not only near the ASP molecules but also near the water molecules. It has been found that it is likely to cause film changes and ruptures. Also, the MD simulation results for the desired surfactant, anionic surfactant, demonstrated that an increase in the surfactant concentration had an adverse effect on the system by hindering the change in the interfacial film. The increase in the temperature along with the enhancement in the adsorption rate of the surfactant results in the better performance of the demulsifier. Taking the MD and quantum results into account, the film deformation is a decisive factor in demulsification. The quantum computation has indicated that the electrostatic interactions play a significant role in selecting the attraction position and adsorption energy of the surfactant molecules.

AbstractPatients with chronic liver disease progressed to compensated advanced chronic liver disease (cACLD), the risk of liver-related decompensation increased significantly. This study aimed to develop prediction model based on individual bile acid (BA) profiles to identify cACLD. This study prospectively recruited 159 patients with hepatitis B virus (HBV) infection and 60 healthy volunteers undergoing liver stiffness measurement (LSM). With the value of LSM, patients were categorized as three groups: F1 [LSM ≤ 7.0 kilopascals (kPa)], F2 (7.1 < LSM ≤ 8.0 kPa), and cACLD group (LSM ≥ 8.1 kPa). Random forest (RF) and support vector machine (SVM) were applied to develop two classification models to distinguish patients with different degrees of fibrosis. The content of individual BA in the serum increased significantly with the degree of fibrosis, especially glycine-conjugated BA and taurine-conjugated BA. The Marco-Precise, Marco-Recall, and Marco-F1 score of the optimized RF model were all 0.82. For the optimized SVM model, corresponding score were 0.86, 0.84, and 0.85, respectively. RF and SVM models were applied to identify individual BA features that successfully distinguish patients with cACLD caused by HBV. This study provides a new tool for identifying cACLD that can enable clinicians to better manage patients with chronic liver disease.
Rigorous analysis of the topologically protected edge states in the quantum spin Hall phase of the armchair ribbon geometry
Authors: Sadeghizadeh Mozhgan , Soltani Morteza , Amini Mohsen 
Published: August 2023

AbstractStudying the edge states of a topological system and extracting their topological properties is of great importance in understanding and characterizing these systems. In this paper, we present a novel analytical approach for obtaining explicit expressions for the edge states in the Kane-Mele model within a ribbon geometry featuring armchair boundaries. Our approach involves a mapping procedure that transforms the system into an extended Su–Schrieffer–Heeger model, specifically a two-leg ladder, in momentum space. Through rigorous derivation, we determine various analytical properties of the edge states, including their wave functions and energy dispersion. Additionally, we investigate the condition for topological transition by solely analyzing the edge states, and we elucidate the underlying reasons for the violation of the bulk-edge correspondence in relatively narrow ribbons. Our findings shed light on the unique characteristics of the edge states in the quantum spin Hall phase of the Kane–Mele model and provide valuable insights into the topological properties of such systems.

Published: August 2023

AbstractNitrogen is a key factor in various physiological and metabolic processes in plants. Providing an adequate supply of nitrogen is essential for improving the total yield and quality of the medicinal plant Artemisia argyi (A. argyi), but the underlying mechanisms of how this nutrient alters the crop remains unclear. In this study, we conducted a series of pot experiments to investigate the agronomic traits and active components in the leaves of A. argyi plants under low and high nitrogen stress. Additionally, we used transcriptome analysis and RT-qPCR to explore the molecular pathways associated with nitrogen stress. Our results demonstrate a dramatic increase in the accumulation of phenolic acids and flavonoids in the low nitrogen (LN) stress group compared to the control (CK), with increases of 40.00% and 79.49%, respectively. Interestingly, plants in the high nitrogen (HN) stress group exhibited enhanced plant growth with larger leaves, thicker stems, and a 3% increase in volatile oil content compared to the CK. Moreover, A. argyi in the HN group displayed a 66% increase in volatile oil concentration compared to the LN group. Our combined transcriptome and q-PCR results indicate that LN stress promotes the expression of genes involved in flavonoid synthesis, while HN stress promotes the expression of genes related to terpene skeleton production and photosynthesis. Taken together, these findings suggest that different gene expression levels under LN and HN stress contribute to the photosynthesis capacity and the accumulation of active ingredients in A. argyi leaves. Our results elucidate the physiological and molecular mechanisms of nitrogen stress on A. argyi secondary metabolites and guide fertilization strategies for plant cultivation.
DichroIDP: a method for analyses of intrinsically disordered proteins using circular dichroism spectroscopy
Authors: Miles Andrew J. , Drew Elliot D. , Wallace B. A. 
Published: August 2023

AbstractIntrinsically disordered proteins (IDPs) are comprised of significant numbers of residues that form neither helix, sheet, nor any other canonical type of secondary structure. They play important roles in a broad range of biological processes, such as molecular recognition and signalling, largely due to their chameleon-like ability to change structure from unordered when free in solution to ordered when bound to partner molecules. Circular dichroism (CD) spectroscopy is a widely-used method for characterising protein secondary structures, but analyses of IDPs using CD spectroscopy have suffered because the methods and reference datasets used for the empirical determination of secondary structures do not contain adequate representations of unordered structures. This work describes the creation, validation and testing of a standalone Windows-based application, DichroIDP, and a new reference dataset, IDP175, which is suitable for analyses of proteins containing significant amounts of disordered structure. DichroIDP enables secondary structure determinations of IDPs and proteins containing intrinsically disordered regions.
Prosocial behavior in competitive fish: the case of the archerfish
Authors: Nafcha Orit , Vilker Dana , Shamay-Tsoory Simone , Gabay Shai 
Published: August 2023

AbstractHumans are social creatures, demonstrate prosocial behaviors, and are sensitive to the actions and consequent payoff of others. This social sensitivity has also been found in many other species, though not in all. Research has suggested that prosocial tendencies are more pronounced in naturally cooperative species whose social structure requires a high level of interdependence and allomaternal care. The present study challenges this assumption by demonstrating, in a laboratory setting, that archerfish, competitive by nature, preferred targets rewarding both themselves and their tankmates, but only when the payoff was equal. With no tankmate on the other side of the partition, they exhibited no obvious preference. Finding evidence for prosocial behavior and negative responses to unequal distribution of reward to the advantage of the other fish suggests that in a competitive social environment, being prosocial may be the most adaptive strategy for personal survival, even if it benefits others as well.

Published: August 2023

AbstractRecently, several constellations of broadband low‐Earth orbit communication satellites, such as Starlink or OneWeb, have started to be deployed to provide global internet access. Based on performed analyses, these emerging constellations are considered promising candidates as space‐based transmitters of opportunity for passive radar applications due to their advantageous characteristics in terms of global coverage, high bandwidth (i.e. better resolution), high received power on Earth surface (i.e. increased maximum range), predictable trajectory, and network density and robustness. However, they also pose certain challenges for the development of passive radar systems due to the necessity to track the satellites with a narrow beam reference antenna, their fast‐relative dynamics which induce range and Doppler migration, and the use of non‐standardised signals with little publicly available information, which in addition are not optimised for radar usage. In this article, these capabilities and challenges are analysed, putting a special focus on the estimation of the achievable performance and on the experimental characterisation of the transmitted signals. To this end, the proposed passive radar architectures and the first developed prototypes are also presented. Showing the potential capabilities of these emerging illuminators of opportunity, the authors aim to promote further development of this technology for multiple applications.

Published: August 2023

AbstractProminent ears (PEs) are the most frequent congenital external ear deformity, occurring in ∼5% of the population. Although the deformity does not usually cause functional difficulties, it can significantly affect the patient's psychological and social health. The authors aim to present the Welsh experience of pinnaplasty, reviewing our outcomes and complications. A retrospective cross-sectional study was performed of all patients undergoing pinnaplasty in Morriston Hospital, Swansea, Wales. We represent the tertiary plastic surgery referral unit across Wales. We included all patients undergoing pinnaplasty between 2015 and 2022 inclusive. We excluded patients undergoing revision procedures or those who had no follow-up. Over the 7-year period, 236 pinnaplasties were performed and 203 were included in the analysis. Ninety-six percent of cases were performed using a cartilage-sparing approach, which represents the mainstay in our unit. The mean follow-up length for our cases was 12 months. Revision procedures were required in 4% of cases. Three hematomas (1.5%) and one (0.5%) wound dehiscence due to infection were recorded and required a return to the operating room. Suture extrusion was noted in 5% of cases (10 patients); 4.5% (9) cases were affected by either hypertrophic or keloid scarring. Across the United Kingdom, cosmetic procedures have come under scrutiny, namely, because of a difficult economic climate. In the era of tight fiscal control in health care, it is pertinent to analyze the outcomes and performance metrics of our operations regularly, thus aiding in the development of an established evidence base to advocate for our respective patients.

Authors: Aranha Kevin N. , Mijar Mahesh , Bhat Malathi 
Published: August 2023

Abstract
Background The most common surgical approach in neurosurgery to diagnose and treat tumors and aneurysms is the transylvian-pterional approach. The classification of Sylvian fissure (SF) was proposed based on pure anatomical observations by Yasargil. The SF is the most identifiable feature of the superolateral brain surface, which divides the parietal and frontal lobes from the temporal lobe which lies below.
Aim The aim was to identify the anatomical variations in SF (bilaterally) in the normal population and to identify its morphological asymmetry.
Setting and Design This was a retrospective, observational descriptive record-based study which was done to identify the anatomical variations and morphological asymmetry in SF (bilaterally) in the normal healthy population using a 1.5-T magnetic resonance imaging (MRI) system.
Materials and Methods The SF was classified into five types. The categorization of the SF was done by MRI, either using T1-weighted images in three planes.
Statistical Analysis Percentage and frequency using SPSS 23.0.
Results In this study, we found that type 4 was most common in the general population of 100 patients. We found type 1 was most common in age groups above 50 up to 60 years of age. Types 2 and 4 SF were found in all age groups. Bilateral presentation of the SF can be considered as symmetric in 85% of the general population and asymmetric in 15% of the population considered in this study.
Conclusion Classification of the SF types on MRI was shown to be reliable and practicable. Sound knowledge of SF anatomy before neurosurgery can help reduce procedure-related morbidity, ischemic lesions, or edema.

Published: August 2023

SummaryA preliminary report on the utility of silastic foam elastomer in the management of 32 open granulating wounds in 30 patients is presented. By offering more wound comfort to the patients and by relieving the work load of surgical residents and nurses, the silicone stent serves a dual function. The ease with which the patients can dress themselves makes such a dressing ideal for domiciliary practice. The cost of silastic foam elastomer may well balance the cumulative cost of conventional dressing material i.e. cotton gauze and bandages and their sterilization.

Published: August 2023

AbstractThe COVID-19 pandemic has led to a global surge in Sinophobia. We examine how Chinese language users responded to COVID-19 on Western social media by compiling a unique database (CNTweets) with over 25 million Chinese tweets mentioning any Chinese characters related to China, the Chinese Communist Party (CCP), Chinese, and Asians from December 2019 to April 2021. Our analysis of Twitter users’ self-reported geographic information shows that most Chinese language users on Twitter originated from Mainland China, Hong Kong, Taiwan, and the United States. We then adopt the Robustly Optimized Bidirectional Encoder Representations from Transformers (RoBERTa) and structural topic modeling to further analyze the sentiments, content, and topics of Chinese tweets during the COVID-19 pandemic. Our results suggest that 61.8% of tweets in our database were contributed by only 1% of Twitter users and 62.2% of tweets were negative toward China. Despite the prevalence of anti-China sentiments, the target entity analysis shows that these negative sentiments were more likely to target the Chinese government and CCP than the Chinese people. Our findings also show that the most popular topics were politics (e.g., Hong Kong protests and Taiwan issues), COVID-19, and the United States (e.g., the US-China relations and domestic issues). Anti-China users focused relatively more on political issues such as democracy and freedom, while pro-China users mentioned cultural and economic topics more. Our social network analysis reveals that these pro-China and anti-China Twitter users lacked in-depth engagement in China-related conversations and were highly segregated from each other. We conclude by discussing our contributions to China and social media studies and possible policy implications.

Published: August 2023

AbstractDue to the outbreak of the Covid-19 pandemic, Chinese university lecturers have experienced increased levels of disappointment and powerlessness due to the changing work environment. An increasing number of lecturers exhibit quiet-quitting intention, which affects their work passion, teaching quality, and so on. However, it is little known about how work-related factors, influence quiet-quitting intention of lecturers. Drawing on the social exchange theory, this study proposes a conceptual model that investigates the effects of work overload, perceived career development opportunities, perceived pay-for performance, affective organizational commitment and work conditions on job burnout, employee well-being, and quiet-quitting intention. Using a quantitative cross-sectional approach, 698 responses were obtained from young Chinese university lecturers. We also employed partial least squares structural equation modeling to analyze and forecast the extent of the impact of this study’s independent variables. The findings revealed that work overload, perceived pay-for-performance, affective organizational commitment, and work conditions significantly affect job burnout and employee well-being. Additionally, job burnout and employee well-being significantly effect quiet-quitting intention, which are moderated by psychological empowerment. Overall, this study contributes to the understanding of the factors influencing quiet-quitting intention among Chinese university lecturers, providing theoretical and practical implications for addressing the challenges arising from the Covid-19 pandemic.
