Authors: Sie-Yi Laura Lim , ChePa Noraziah , Yusoff Noraini , Wan Yahaya Wan Ahmad Jaafar , Ishak Rusdi
Published: August 2022

Game interventions have been demonstrated to have significant effects in terms of increasing treatment adherence and accessibility in the health profession. The use of game has a great therapeutic influence on the experience when doing recovery workouts. Due to its strengths, a game-based intervention model for elderly with memory disorder is proposed. The proposed model consists of both exogenous and instantaneous factors as its main components. Nine exogenous factors are attitude, emotion, skill, belief; support, attractive, fun, reminiscence, complexity. Six instantaneous factors are perceived focus, enjoyment, motivation, comfortability, perceived control, and boredom. To ensure its correctness, verification procedure has been carried out by using an expert review approach involving five experts from three different domains. Qualitative and quantitative feedbacks from the experts are used in refining the proposed model. Our works can be extended by incorporating other related theories to strengthen the model such as reminiscence and flow theories. The improved model is significant in providing a guideline of game-based intervention to other related domains. Our works are believed as effective in improving cognition among elderly, the interesting and positive findings can be attributed to the integration of digital game and psychotherapy for elderly, particularly those with memory disorder symptoms.

Published: August 2022

The idea of bacterial scanning is realistic not only in operating rooms but also everywhere around human because bacteria and viruses grow everywhere. It is the job of individual and the community to keep the environment hygiene at all times. Several devices such as sterilizers, ultraviolet (UV) and autoclave are helpful to clean door handles, toilets, washbasins, railings, keyboards, seats, etc. However, those devices require either physical intact or chemical exposure to disinfect the areas without initial identification whether the bacteria are presence or not. If bacteria can be detected at the earliest time possible, preventive and initiative action can be taken and harmful bacteria can be prevented from infecting towards any personal. Hence, the development of Scan De Microbes is intended to address this situation. This system was developed as a scanning device to indicate the accumulation of bacteria on user’s hand where most interaction between a person and the surrounding is done by hand (i.e. eating, opening door, etc). The developed device is able to capture image of the hand which was illuminated by UV light under dark surrounding. Due to wide range of smart phone camera specification, all captured images were converted to a standard size image that acceptable for the application to process. The captured images later were processed and the orange color spot that appeared on the hand was calculated due to reaction of the bacteria with the hand. Results showed the estimated percentage of the accumulated bacteria on the hand from the processed images. The result page in the developed application was then displayed. This data later on can be saved and share wirelessly using Bluetooth of any apps available on the smartphone. Multiple images with different percentage of accumulated bacteria were tested using the application. The finding is conclusive and can be used as a preliminary accessor tool to investigate or detect any potential bacteria that already accumulate on the user’s hand. This development may assist the user in global warfare with the invisible enemy known to man as germ or bacteria in order to improve the livelihood and well-being of humans.

Authors: Ahmed Alnagrat Ahmed Jamah
Published: August 2022

Today, learning environments (LEs) are proceeding towards virtual environments (VEs) in which a sense of reality can be presented in three dimensions (3D) and a sense of inclusion can be experienced. A virtual learning environment (VLE) can be presented in a more realistic and visual manner with the use of innovative technologies such as virtual reality (VR), mixed reality (MR), and augmented reality(AR). This paper examines how extended reality (XR) approaches and its applications are transforming virtual learning environments in the context of human education and learning. A systematic literature review from the Scopus, Web of Science, IEEE, ACM and Google Scholar databases was conducted in order to better understand XR's contributions to human education as well as learning.The potential uses of XR technology have been discussed in terms of its structure, past, present, and future directions of XR concerning education.The research conducted in this context has determined that XR is mostly being used in fields of education, learninig and simulating an emergency situation. XR technology can be applied to solve problems without causing harm to people or property, particularly in emergency scenarios and safety training. Finally, this study offer several novel approaches for addressing these challenges, as well as potential directions for future researchers seeking to specialize in using these emerging technologies for human education.

Published: August 2022

Nowadays technology development in real life will reflect on education inexorably. Today, the concept of Extended Reality (XR) technologies (XRs), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), as very promising technological tools for education. The purpose of these technologies is to facilitate human life. In this context, educational technologies create new opportunities for students and teachers every day especially in education field. With various virtual environments (VE) and imaging systems, content that needs to be learned can be presented independently of school and classrooms in a low-cost and safe environment. As a result, teachers can create their own content with various applications, providing them with freedom of flexibility, and creativity. In this context, it is seen that XR has started to be used in various fields in education. When these fields and subjects are examined, it is observed that there is a concentration in the fields of education. The purpose of this narrative review is to describe the accelerators of XR (VR, AR, MR) technology in education settings. This literature review was conducted by conducting a systematic search of relevant articles and literature reviews through the university's online library, Google Scholar, Web of Science, IEEE Xplore, and the ACM Digital Library. In this paper, the authors demonstrate the main components of XR technology in the educational process. A comprehensive review of XR technology including education, and learning was provided. The authors identify limitations and conclude with future work of XR in educational uses.

Published: August 2022

Bone loss is risen due to fractures, surgeries and traumatic injuries. Scientists and engineers work over the years to find solutions to heal and accelerate bone regeneration. Bone grafting technique has been utilised which projects significant improvement in bone regeneration area. An extensive study is essential on the relation between the mechanical properties of bone scaffolds and the design of bone scaffolds in forecasting permeability access to promote bone growth and nutrient distribution. In reducing cost and time, mechanical simulation analyses are beneficial to simulate the relation. There are abundant of review works on the mechanical simulation analyses towards orthopaedic metallic implants. While the review on simulation analyses towards bone scaffolds are scarce. Therefore, this review study is intended to expose the utilisation of computer simulation analysis, specifically Solidworks® software in modelling three-dimensional (3D) scaffold models, performing mechanical simulation and analysing bone scaffold structure. The data were collected from three main sources of Google search, Scopus search and Science Direct search. From this review procedure, there are various computational software have been combined and used to perform several types of simulation analyses on bone scaffolds including Solidwork, Ansys, Abaqus, COMSOL Multiphysics, MATLAB etc. Among the simulation analyses, two main tests that can be simulated are mechanical test and fluid modelling. Solidwork® as one of the computer-aided design softwares has been extensively used to design two and 3D models. The advancement of this software on the performance of mechanical simulation analyses has also extended its application towards variety of applications including on bone scaffold evaluation. There are several parameters which are necessary to be set prior to the conduction of mechanical simulation analysis such as applied forces, material properties, mesh properties and boundary condition. As a conclusion, Solidwork® software is applicable to be used as a 3D modelling software to design bone scaffolds and to perform mechanical simulation analyses.

Cardiovascular disease (CVD) is a heart related disease and is the top silent killer in worldwide. Frequent electrocardiogram (ECG) monitoring for patients with CVD is vital to check if arrhythmia occurs. Though there are lots of commercialized portable ECG monitoring device available, many of them are dedicated to professional clinical staff with complex user interface, or only targeted to specific arrhythmia for home monitoring with lack of data management system. In this study, an in-house developed ECG monitoring device was integrated with an Android-based mobile application through Bluetooth wireless communication and implements Google Cloud Technology. The Android-based mobile app supports main features of real-time ECG graph display, automated location detector, data management system and simple arrhythmia detection. The ECG graph displays acquired ECG signal in real-time by ­in-house ECG acquisition unit through Bluetooth wireless communication and stored as text files in phone’s local memory. Firebase Authentication and Firebase Storage based on Google Cloud technology are implemented for data management system development. This allows users and administrators to upload or access data securely through online Google Cloud Platform. Three types of heart rhythm, namely normal sinus rhythm, bradycardia and tachycardia can be classified based on heart rate analysis. Smartphone’s location service is enabled to allow user shares their location with caretaker in emergency case. The final solution utilizes the Internet-of-Things (IoT) technology to facilitate heart disease management towards telemedicine applications.
Cavitation Suppression and Design Optimization in a Cryogenic Liquid Turbine Expander Based on Thermodynamic Cavitation and Entropy Production Analysis
Authors: Sun Shan , Song Peng , Sun Jinju , Sun Wanyou
Published: August 2022

Cryogenic liquid turbine expanders have emerged quite recently as a replacement of J–T valve for enhancing energy efficiency of industrial systems, such as air separation units (ASUs) and Supercritical Compressed Air Energy Storage systems. In the liquid turbine expander, the rotating impeller-induced swirling flow and cavitation are essentially significant and intensive, which requests some in-depth work toward a thorough understanding flow physics and then effective attenuation. This study aims at effectively mitigating the swirling flow and cavitation. The entropy production analysis method (EPAM) is proposed to characterize the swirling flow and cavitation. It is then incorporated with the improved cavitation and turbulence models and validated through the simulation of the Hord's liquid nitrogen hydrofoil. To mitigate the swirling flow and subsequent cavitation, the design optimization method is developed, in which a novel optimization objective function is constituted by incorporating the local entropy production rate and vapor volume fraction to capture the mechanical energy dissipation and cryogenic cavitating flow physics; the non-uniform relational B-Splines and free form deformation (NURBS–FFD) parametric method is used to facilitate a flexible variation in impeller blade and diffuser vane geometries. It is solved within cfx frame by means of the particle swarm optimization (PSO) algorithm coupling the Kriging-based adaptive surrogate model. With the design optimization, the impeller and vaned diffuser tube geometries are collaboratively fine-tuned, and the mechanical energy dissipation and cavitating flow across both the impeller and vaned diffuser tube is effectively mitigated.
Probing cosmic string spacetime through parameter estimation
Authors: Yang Ying , Jing Jiliang , Tian Zehua
Published: August 2022

Quantum metrology studies the ultimate precision limit of physical quantities by using quantum strategy. In this paper we apply the quantum metrology technologies to the relativistic framework for estimating the deficit angle parameter of cosmic string spacetime. We use a two-level atom coupled to electromagnetic fields as the probe and derive its dynamical evolution by treating it as an open quantum system. We estimate the deficit angle parameter by calculating its quantum Fisher information(QFI). It is found that the quantum Fisher information depends on the deficit angle, evolution time, detector initial state, polarization direction, and its position. We then identify the optimal estimation strategies, i.e., maximize the quantum Fisher information via all the associated parameters, and therefore optimize the precision of estimation. Our results show that for different polarization cases the QFIs have different behaviors and different orders of magnitude, which may shed light on the exploration of cosmic string spacetime.

Impact of Cattaneo–Christov double diffusion on 3d stagnation point axisymmetric flow of second-grade nanofluid towards a riga plate
Authors: Nadeem Sohail , Ishtiaq Bushra , Almutairi Shahah , Ghazwani Hassan Ali
Published: August 2022

The main purpose of this study is to scrutinize the axisymmetric flow of second-grade nanofluid with variable viscosity near a stagnation point under the influence of the Cattaneo–Christov double diffusion model. A Riga plate is assumed to be the source of the three-dimensional flow. The consequences of the anisotropic slip conditions and the Buongiorno model are included in the formulation of the constituting equations of the fluid flow. The highly nonlinear ordinary differential equations are developed with the executions of the relevant similarity transformations on the problem’s governing equations. For the asymptotic analysis, the appropriate expansions are implemented on the nonlinear system of ordinary differential equations. The bvp4c technique of the MATLAB package is implemented on the nonlinear ordinary equations for the numerical solutions. In order to explore the impact of the parameter slip factor on the pattern of velocities, temperature, and concentration profiles, several graphs are plotted. From this study, we conclude that the normalized velocities boost up with the amplification in the slip factor parameter but the temperature profile exhibits a declining behavior. The concentration field exhibits the accelerating behavior relative to the slip parameter.

Published: August 2022

This paper deals with a unified presentation traveling wave solutions for the Mukherjee–Kundu equation which is a variant of the well-known nonlinear Schrödinger equation. A Weierstrass function approach has been employed to derive a Weierstrass elliptic function solutions, which can be reduced to the Jacobian elliptic function solutions through the conversion transformations. Due to the reductions of the Jacobian elliptic function solutions, the solitary wave solution and the trigometric period wave solution can be found by [Formula: see text] and [Formula: see text], respectively. In addition, the features of the obtained traveling wave solutions are represented graphically with the appropriate parameters.
EXPLORING THE RELATIONSHIP BETWEEN MULTI-DIMENSIONAL DIGITAL READINESS AND DIGITAL TRANSFORMATION OUTCOMES
Authors: TRISCHLER MATTHIAS FABIAN GREGERSEN , LI-YING JASON
Published: August 2022

Given that many large-scale digital transformations fail, researchers have sought to identify factors that may increase the likelihood of success when institutionalising organisational changes. The importance of digital readiness for digital transformations has attracted increasing interest recently in this context. However, prior research has not addressed which specific aspects of digital readiness links to digital transformation outcomes under a given context. This study contributes to filling this gap in the literature. Using a sample of 207 Danish SMEs, we conduct an ordinal regression analysis to find out which dimension(s) of digital readiness are important to digital transformation outcomes for small companies. The results show that the strategy and technology dimensions have a positive impact on the dependent variables. The results further highlight the importance of a company’s capacity for change to deploy existing resources. Our results have strong implications for practitioners, as they provide guidance on what to focus on with respect to digital readiness at the outset of a firm’s digital transformation journey.

The purpose of this paper is to use image processing technology to study and analyze the diagnosis of aerobics sports injury, so that the diagnosis results can be obtained more quickly and effectively. This paper first introduces the image processing technology and then analyzes the sports injury in colleges and universities. Firstly, the algorithm formula of image processing technology is given, and then the algorithm is introduced into the dynamic analysis of aerobics injury diagnosis. The two are compared through example analysis. The experimental results show that joint strain, sprains, and muscle strain are the main types of sports injury of College Aerobics students, reaching 59, 50, and 31 times, respectively. When using image processing technology in the diagnosis of sports injury, the diagnosis results can be obtained quickly and effectively.
Effects of Aspirin on Odontogenesis of Human Dental Pulp Cells and TGF-β1 Liberation from Dentin In Vitro
Authors: Khampatee V. , Zhang C. , Chou L.
Published: August 2022

Aim. This in vitro study aimed to investigate the roles of aspirin (ASA) and its concentrations on the odontogenesis of human dental pulp cells (HDPCs) and to investigate the influence of ASA on TGF-β1 liberation from dentin. Methodology. HDPCs were cultured in a culture medium with 25, 50, 75, 100, and 200 μ·g/mL ASA and 0 μ·g/mL ASA as a control. The mitochondrial activity of HDPCs was assessed using an MTT assay. Crystal violet staining and triton were used to evaluate cell proliferation rates. ALP activity was measured with a fluorometric assay. Expressions of DSP and RUNX2 were determined with the ELISA. DSP and RUNX2 mRNA levels were measured with RT-qPCR. Alizarin red staining was conducted to evaluate the mineralized nodule formation. Dentin slices were submerged in PBS (negative control), 17% EDTA (positive control), and ASA before collecting the solution for TGF-β1 quantification by the ELISA. The data were analyzed by the t-tests and ANOVA, followed by the Tukey post hoc tests.

P

values < 0.05 were considered statistically significant. Results. The results showed that 25–50 μ·g/mL ASA promoted mitochondrial activity of HDPCs at 72 h (

P
<
0.05

) and yielded significantly higher proliferation rates of HDPCs than the control at 14d and 21d (

P
<
0.001

). All concentrations of ASA promoted odontogenic differentiation of HDPCs by enhancing the levels of DSP and RUNX2, their mRNA expression, and mineralization in a dose-dependent manner. Also, ASA yielded significantly higher TGF-β1 liberation after conditioning dentin for 5 min (25, 200 μ·g/mL;

P
<
0.001

) and 10 min (200 μ·g/mL;

P
<

). Conclusions. This in vitro study demonstrated that ASA, especially in high concentrations, promoted the odontogenesis of HDPCs and TGF-β1 liberation from dentin, showing the potential of being incorporated into the novel pulp capping materials for dental tissue regeneration.
Camrelizumab-Related Lethal Arrhythmias and Myasthenic Crisis in a Patient with Metastatic Thymoma
Authors: Zhang Bo , Gyawali Laxman , Liu Zengzhang , Du Huaan , Yin Yuehui
Published: August 2022

Immune checkpoint inhibitors (ICIs) have emerged in recent years as promising treatment options for several malignant tumors. However, ICI therapy has also been associated with various immune-related adverse events (irAEs), especially for patients with preexisting autoimmune status, which sometimes can be life-threatening. A 68-year-old woman diagnosed with metastatic thymoma was treated with camrelizumab, a new ICI, as her antitumor protocol. Eleven days after the first dose of camrelizumab, the patient was admitted to our hospital with symptoms of dyspnea, fatigue, and poor appetite. Workups on admission indicated dramatically elevated transaminase, troponin I, creatine kinase, and a new-onset conduction abnormality on electrocardiography. After detailed evaluation, ICI-related myocarditis, myositis, and hepatitis were diagnosed, and therapies including intravenous methylprednisolone were administered. Coronary angiography was performed to exclude acute coronary syndrome due to dynamic electrocardiography changes on day 3. She lapsed into a coma with respiratory muscle failure on the next day, which was highly suspected of myasthenic crisis. Mechanical ventilation and higher dose of methylprednisolone plus intravenous immunoglobulin were applied immediately. However, the third atrioventricular block occurred within the same day, and an urgent temporary pacemaker was placed. More seriously, refractory ventricular tachycardia (VT) occurred subsequently, and even multiple antiarrhythmic drugs used in combination failed to alleviate the VT storm. On day 5 of hospitalization, she suffered from ventricular fibrillation and died of cardiac arrest. In clinical practice, close follow-up should be conducted after ICI treatment, especially for patients already with or at high risk for autoimmune disorders. A multidisciplinary team approach is of importance for better management of patients with multiple organ involvement.
Electrogalvanism in Oral Implantology: A Systematic Review
Authors: Amine Meriem , Merdma Wiam , El Boussiri Khalid
Published: August 2022

Purpose. The objective of this work is to study galvanic corrosion of different couples of prosthetic and implant alloys through the realization of a systematic review. Materials and Methods. An electronic search was performed on Pubmed, Google Scholar, Scopus, ScienceDirect, EbscoHost, and Web of Science for published studies related to electrogalvanism in oral implantology. The keywords used were “dental implants” and “galvanic corrosion.” Two independent readers read the scientific articles. Results. From 65 articles initially identified, only 19 articles met the eligibility criteria. The evaluation of the selected articles allowed us to determine the parameters compared, such as the resistance to galvanic corrosion, the influence of fluorine and pH on the electrochemical behavior, and the release of metal ions and their cytotoxicity. Indeed, Ti6Al4V and precious alloys coupled to titanium were found to be the most resistant to galvanic corrosion, followed by cobalt-chromium alloys and nickel-chromium alloys which were least resistant. This resistance decreases with increasing fluorine concentration and with decreasing pH of the environment. Discussion. The implant-prosthetic system’s galvanic resistance is influenced by many intrinsic factors: alloy composition and surface condition, as well as extrinsic factors such as pH variations and amount of fluorine. The effects of oral electrogalvanism are essentially the result of two main criteria: effects due to electric currents generated by corrosion and effects due to the release of metal ions by corrosion. Conclusion. To avoid this phenomenon, it is wise to follow the proposed recommendations such as the use of the minimum of distinct metals as much as possible, favoring the commercially pure titanium implant of Ti6Al4V, opting for the choice of couples, titanium/titanium, favoring daily mouthwashes of 227 ppm of fluoride, and avoiding fluorinated acid solutions.
Meta-Analytical Approach to the Impact of Corpus-Driven Teaching on Foreign Language Acquisition
Authors: Li Lexi Xiaoduo
Published: August 2022

Corpus linguistics is an emerging discipline in contemporary linguistics. Corpus refers to a large number of real used languages, which are collected, classified, stored, coded, or marked by computer to form a huge electronic resource library for users to learn or conduct research. Nowadays, corpus is gradually applied to English teaching, but corpus is mostly used in undergraduate teaching, and it is still in its infancy in higher vocational English teaching. Starting from this realistic background, in this work, a meta-analysis was conducted to analyze corpus-driven instruction on foreign language acquisition. The introduction of meta-analysis and the related introduction of chaotic communication system were carried out, and the hardware architecture of the system was designed. In the experiment, the error corpus was collected and sorted out and used as a sample. The comparative experiment method was adopted, which meant that two or more experimental groups were set up, and the relationship between various factors and experimental objects was explored through the comparative analysis of the results. Experimental results showed that judging from the average correct rate, the correct rate of the questionnaires for international students generally increased with the level of the international students. It also showed from another aspect that the higher the level of international students, the less the impact of the English translation of words on their acquisition process. The subject of meta-analysis of the impact of corpus-driven teaching on foreign language acquisition has been well completed.

BACH2 in TRegs Limits the Number of Adipose Tissue Regulatory T Cells and Restrains Type 2 Immunity to Fungal Allergens
Authors: Contreras Amanda , Wiesner Darin L. , Kingstad-Bakke Brock , Lee Woojong , Svaren John P. , Klein Bruce S. , Suresh M.
Published: August 2022

FoxP3+ regulatory T cells (Tregs) are essential for self-tolerance and moderating tissue-damaging inflammation. Tregs that develop and mature in the thymus are classified as central Tregs or effector Tregs based on whether Tregs predominately inhabit secondary lymphoid organs (central Tregs) or tissues (effector Tregs). By generating mice that are conditionally deficient for Bach2 in peripheral Tregs, we have examined the role of Bach2 in regulating Treg homeostasis and effector functions. Unlike global and T cell-specific Bach2-deficient mice, Treg-specific Bach2 ablation did not result in unprovoked TH2 inflammation in the lungs. However, Bach2 deficiency in Tregs led to augmented expressions of IRF4, BATF, and GATA3 and a significant increase in the accumulation of ST2 (IL-33R)+ve effector Tregs in the spleen and visceral adipose tissue (VAT) but not in the lungs. Enhanced Bach2-deficient Treg numbers in VAT was not linked to hyperresponsiveness to exogenous IL-33 in vivo. Most strikingly, Treg-specific Bach2 deficiency resulted in enhanced fungal protease-induced Type 2 allergic inflammation in the lungs, with no detectable effects on Type 1 responses to systemic or respiratory viral infections. In summary, we ascribe vital roles for Bach2 in peripheral Tregs: as a transcriptional checkpoint to limit precocious differentiation into effector Tregs in lymphoid tissues and as a regulator of the functional program that restrains Type 2 but not Type 1 inflammation in lungs. Results presented in this manuscript implicate dysregulated Tregs in the pathogenesis of airway hypersensitivities, asthma, and other allergic disorders.
Reproductive Women’s Knowledge on Possibility of Pregnancy after Birth but before Resumption of Menstruation and Its Associated Factors in Ethiopia: A Population-Based Study Using the 2016 Ethiopian Demographic Health Survey
Authors: Aragie Teshome Gebremeskel , Gedion Girma Seyoum
Published: August 2022

Introduction. Worldwide, specifically in developing countries, women believe that a woman cannot become pregnant unless she sees her first postpartum menstruation. Due to this knowledge gap, most women did not use any contraceptives till their 1st postpartum menstruation. Hence, about 44% of women were susceptible to unintended pregnancy in the postpartum period. Assessing women knowledge on possibility of pregnancy after giving birth but before returning of menses and its associated factors will help to increase women’s recognition on the issue and for early commencement of appropriate postpartum family planning methods to reduce burden of unintended pregnancy. Objective. To assess the level of knowledge on possibility of pregnancy after giving birth but before returning of menses and its associated factors among reproductive women in Ethiopia. Methods. A secondary data analysis using the 2016 Ethiopian Demographic Health Survey was employed. Samples were selected using two-stage stratified sampling technique.

Reproductive women’s level of knowledge on the possibility of pregnancy after giving birth but before returning of menses was low. Factors associated with being knowledgeable on the issue were identified. Therefore, strategies should be developed to increase their level of knowledge for reducing unintended pregnancy and its complications by integrating family planning counseling with infant immunization services.

Published: August 2022

In order to better prepare and analyze bacterial cellulose-based composite hydrogels, an experimental method based on scanning electron microscopy was proposed. The specific content of the method is to observe the hydrogel through scanning electron microscope, to observe the space between molecules through experiments, and to improve the effect of bacterial cellulose preparation of hydrogel. The experimental results show that the gel preparation effect is best when PEG concentration is not more than observed by scanning electron microscope. It is better to prepare bacterial cellulose complex hydrogel by scanning electron microscopy.

The description of the first zoea stage of Tetraxanthus rathbunae Chace, 1939, the third known zoea of Pseudorhombilidae and the first for Tetraxanthus, was carried out from laboratory hatched larvae. Their morphology differs from other pseudorhombilid species previously described primarily in the number and type of setae on the antennule, antennal exopod, maxilla, first maxilliped, and second maxilliped. These zoeae, however, share the same number of spines on the carapace (rostral, dorsal, and lateral), absence of the endopod on the antenna, long and well-developed spinose protopod, maxillary exopod with four marginal plumose setae and a robust posterior process, the absence of setae on the basis of the second maxilliped, and the presence of three lateral spines on each side of the furca. The results obtained in the present study are of great importance in being only the third known first stage pseudorhombilid zoea and the first for the Tetraxanthus, as well as in contributing to the identification of brachyuran planktonic zoea. Additionally, it also provides information that can help elucidate pseudorhombilid phylogeny.

Authors: ZHENG YULIN , GUO JIANJUN , ZHANG RUNZHI
Published: August 2022

This paper deals with five species of Arrenurus Dugès, 1834 from P. R. China. Arrenurus (Truncaturus) linguaus sp. nov., Arrenurus (Arrenurus) pseudodistinctus sp. nov. and Arrenurus (Arrenurus) yanchengensis sp. nov, are new to science; Arrenurus (Arrenurus) crassicaudatus Kramer, 1875 and Arrenurus (Megaluracarus) ussuriensis Sokolow, 1931 are recorded for the first time for the Chinese fauna. Arrenurus (Truncaturus) linguaus sp. nov. can be distinguished by tongue-shaped hyaline petiole, trapezoid hyaline membrane, and more or less triangular acetabular plates. Arrenurus (Arrenurus) pseudodistinctus sp. nov. can be distinguished by the median of petiole enlarged, obviously wider than the front and rear ends; ligulate process well-developed and fishtail-shaped; hyaline membrane trapezoid. Arrenurus (Arrenurus) yanchengensis sp. nov can be distinguished by a short hyaline membrane and extending to the base of the well-developed pygal lobes; petiole lobes have the same length as the petiole. Detailed descriptions and illustrations of the new and newly recorded species are given in this paper.

Published: August 2022

Percutaneous transcatheter mitral valve reconstruction in edge to edge fashion is a well-established option in inoperable or high peri-operative risk patients with severe, symptomatic mitral valve regurgitation. MitraClip in combination with medical treatment improves survival and reduces hospitalization rates compared with optimal medical therapy alone in well selected patients. Clip-associated endocarditis is a rare complication with only few reported cases in the literature. We present a case of late infective endocarditis post Mitral Clip implantation and also review the literature regarding this new rare condition.

Published: August 2022

Based on our experimental study of spectral characteristics of an improved compact CO laser system, the prospects of using such a laser system for solving urgent problems of atmospheric sounding were demonstrated. An increase in the number of laser lines due to intracavity generation of the second harmonic and sum-frequencies in a nonlinear zinc germanium phosphide (ZnGeP2) crystal enriches capabilities of the laser. It was shown that such a CO laser system with frequency conversion in ZnGeP2 crystal can be used for detection and measuring concentration of at least 14 minor natural and pollution gases components of the atmosphere. The advantages and disadvantages of various laser operation modes, and the prospects for using its radiation for atmospheric remote sensing in various spectral ranges are discussed.
Terahertz Spectroscopy and Ab-Initio Vibrational Analysis of Two Crystalline Forms of 5,5-Diethylbarbituric Acid
Authors: Kumazawa Ryoichi , Sawada Keisuke , Toriumi Yoshiharu , Yoshikawa Masanobu
Published: August 2022

Terahertz (THz) absorption spectra of the two crystalline forms of 5,5-diethylbarbituric acid (barbital) were measured with THz time-domain spectroscopy (THz-TDS). The spectra exhibited the dissimilarity between the two forms. Identification of the polymorphs and quantitative analysis of the two forms are possible by THz-TDS. Further, we performed ab-initio calculations of the vibrational modes considering the crystal structures of the two forms, and the results were in good agreement with the experimental data. We discuss the difference between the THz absorption spectra of the two forms.
The Extraterritorial Voting Rights and Restrictions Dataset (1950–2020)
Authors: Wellman Elizabeth Iams , Allen Nathan W. , Nyblade Benjamin
Published: August 2022

This paper introduces the Extraterritorial Rights and Restrictions dataset (EVRR), the first global time-series dataset of non-resident citizen voting policies and procedures. Although there have been previous efforts to document external voting, no existing data source simultaneously captures the scale (195 countries), time frame (71 years), and level of detail concerning extraterritorial voting rights and restrictions (over 20 variables). After a brief overview of prior datasets, we introduce EVRR coding criteria with a focus on conceptual clarity and transparency. Descriptive analysis of the dataset reveals both the steady expansion of extraterritorial voting as well as several regional and temporal trends of voting rights restrictions. Finally, we revisit and extend the work of two groundbreaking cross-national studies focused on the causes and effects of external voting rights. Using EVRR data we demonstrate that including more fine-grained aspects of extraterritorial voting provisions in these analyses improves understanding of important political and economic outcomes.
Brokering Bureaucrats: How Bureaucrats and Civil Society Facilitate Clientelism Where Parties are Weak
Authors: Cornell Agnes , Grimes Marcia
Published: August 2022

Clientelism, the exchange of selective rewards for votes, is fraught with commitment problems and questions remain regarding how it occurs in settings lacking strong parties. In such settings, we argue, bureaucrats can act as brokers using their own networks. Bureaucrats can use their discretionary power to cultivate reciprocal relations with voters and leverage this political capital in negotiations with politicians to secure career advancements. As brokering requires networks, we hypothesize that bureaucrats with connections to civil society are more likely to exhibit brokering behavior, and especially in localities with stronger civil society. Original survey data of bureaucrats ( N=1300) in a context of weak parties, Peru’s 25 regions plus the city of Lima, show that bureaucrats with connections to civil society are more likely to exhibit brokering behavior. Political and party connections are weaker predictors of brokering. The paper thus shows how locally connected bureaucrats may aid in coordinating clientelism.
