Published: April 2022

This study initiallyinvestigated decay resistance of preservative injected poplar and its infection mechanismof preventing white rot fungi. The living poplar was injected with different concentrations (0.0, 0.5, 1.0 and 1.5 wt.%) of alkaline copper quaternary (ACQ). Using thescanning electron microscopy, the process of preservative injected poplar wood preventing white rot fungi infection at different tree heights were examined. The decay resistance test results showed that the decay resistance of preservative injected poplar at different tree heights was significantly different. With the increase in tree height, the decay resistance decreased, and the higher the ACQ concentration, the better the decay resistance. The white rot fungi infested the poplar wood with the vessels as the breakthrough point, being spread to other cells through pits. The white rot fungi degraded wood cell walls by secreting enzymes and preferentially degraded the parenchyma cells.

Authors: KONUKCU ARIF CAGLAR
Published: April 2022

The fracture behavior of southern yellow pine (Pinus taeda L.) was experimentally analyzed in the radial-longitudinal and the radial-tangential crack propagation systems using asingle-edge-notched bending test method in mode I loading condition. Three fracture parameters, the initial slope, the fracture toughness, and the specific fracture energy, were determined from the obtained load-deformation curves of each test sample. The results were statistically analyzed and compared with each other using the independent samples t-test. Theradial-longitudinal crack propagation system had a significantly greater fracture toughness than in the radial-tangential crack propagation system. The stiffness in the radial-longitudinal system was also significantly higher than in the radial-tangential system. It was observed that the crack growing in the tangential direction needed more energy per unit area to separate awood sample into two halves. However, there was no significant difference between thespecific fracture energy values of crack propagationsystems.

The fear of childbirth is a mental health problem that involves a severe, excessive fear of pregnancy and the time of birth. This condition is also called "tokophobia" or, better said, birth phobia. This review is based on information from articles in the literature published between January 1, 2001 and November 1, 2021 in PubMed, ScienceDirect and Google Scholar using the following keywords: fear of childbirth, symptoms, causes, tools, psychological interventions. In this review, we discussed the types of fears women have about pregnancy and childbirth, the instruments that is used for assessing the fear of childbirth, and how to cope with and overcome this fear. According to the literature, the role of psychological counseling for women facing fear of childbirth is important in the optimal management of emotional symptoms associated with pregnancy.

Multiple myeloma (MM) is a plasma cell dyscrasia, accounting for 10% of all hematological malignancies, which translates into a global age-standardized incidence and mortality rate of 2:1 per 100.000 and 1.39 per 100.000 respectively (1). Kidney disease is a very common complication of MM, increasing the mortality and being a poor prognostic factor. Renal impairment is often the first reason for patient admission, leading to the plasma cell dyscrasia as being the cause. 40% of patients with cast nephropathy had previously undiagnosed myeloma (2).The aim of this paper is to show that Prompt diagnosis and initiation of therapy warrants better patient survival and delays, or even prevents organ damage in multiple myeloma.

The aim of this work was to describe a series of cases of familial dysbetalipoproteinaemia (FD) - a rare recessive disorder of lipid metabolism. The study included 18 patients of both sexes, mean age was 42.4 years. Quantitative determination of total cholesterol (TC) and triglycerides (TG) was carried out by a unified enzymatic method, high density lipoprotein (HDL) and low-density lipoprotein (LDL) - by a direct homogeneous method. The APOE gene rs7412 variant was determined by real-time polymerase chain reaction (PCR) using adjacent samples and by melting reaction products after PCR. The frequency of FD according to DNA analysis among 367 patients with different types of hyperlipidemia was 4.9%. CHD was detected in 27.8% of patients. Different types of xanthomas were detected in 22.2% of patients. When comparing the initial lipid profile of patients with FD and those in the control group, significantly higher levels of TC, TG, state Budget-funded Institution National Medical Research center of cardiology of the Ministry of Health of the Russian Federation LDL-C and non-HDL-C were observed, while plasma HDL-C levels were significantly lower than in the control group. On lipid-lowering therapy (statin and/or fibrate), the average levels of TC, TG and non-HDL cholesterol decreased approximately 2 times from baseline (p<0.002), and LDL decreased 1.5 times (p<0.008). The goal level of non-HDL-C among patients with high cardiovascular risk (<2.6 mmol/l) during therapy was not achieved in anyone, and high risk (<3.4 mmol/l) was achieved only in 2 of 5 patients. The data obtained show that, despite the favorable changes in the lipid profile, many patients with FD on current therapy remain untreated; therefore, to increase the effectiveness of therapy, it is necessary to increase the dose of statin (in the absence of contraindications) and/or combine statins with fibrates.

Spotted scat Scatophagus argus is an important brackishwater species predominantly inhabited in south-west coast of Bangladesh. The aim of this study was to develop a hormonal induced reproduction protocol of farm-domesticated S. argus along with larvae rearing techniques. Synthetic gonadotropin releasing hormone analogue (S-GnRHa) was injected at the dose of 60:30 μg/kg BW (Female: Male). In female fish 20% of the total dose was applied as priming dose and 12 hours later 80% as resolving dose. The latency period ranged from 32 to 36 h was determined by observing the time between first injection and ovulation. However, after achieving full oocyte maturation and ovulation, eggs were collected by stripping and fertilization was carried out using pooled sperm from male. The mean ovulation, buoyancy, fertilization and hatching rate were found 70±1.8; 68±7.7; 40±2.3% and 53±5.2% respectively. Over the embryonic development following stages were witnessed in embryos: meroblastic cleavage (2-cell), blastula, gastrula and pharyngula. Maximum embryos hatched within 19 hr post fertilization at 28±2.0°C temperature and 28±2.0 ppt salinity. In this study, we dispense the first information on the reproduction of spotted scat in captive condition using S-GnRHa and the optimal dose limit and larval rearing techniques are established. Further studies are warranted to develop the larvae into juvenile stage under variable environmental conditions to increase the fertilization, hatching rate and survival of embryos.

Bayesian Inference in Single-line Spectroscopic Binaries with a Visual Orbit

Published: April 2022

We present a Bayesian inference methodology for the estimation of orbital parameters on single-line spectroscopic binaries with astrometric data, based on the No-U-Turn sampler Markov chain Monte Carlo algorithm. Our approach is designed to provide a precise and efficient estimation of the joint posterior distribution of the orbital parameters in the presence of partial and heterogeneous observations. This scheme allows us to directly incorporate prior information about the system—in the form of a trigonometric parallax, and an estimation of the mass of the primary component from its spectral type—to constrain the range of solutions, and to estimate orbital parameters that cannot be usually determined (e.g., the individual component masses), due to the lack of observations or imprecise measurements. Our methodology is tested by analyzing the posterior distributions of well-studied double-line spectroscopic binaries treated as single-line binaries by omitting the radial velocity data of the secondary object. Our results show that the system’s mass ratio can be estimated with an uncertainty smaller than 10% using our approach. As a proof of concept, the proposed methodology is applied to 12 single-line spectroscopic binaries with astrometric data that lacked a joint astrometric–spectroscopic solution, for which we provide full orbital elements. Our sample-based methodology allows us also to study the impact of different posterior distributions in the corresponding observations space. This novel analysis provides a better understanding of the effect of the different sources of information on the shape and uncertainty in the orbit and radial velocity curve.
Search for Stellar Flybys in the Sco-Cen OB Association with the Gaia DR2

Published: April 2022

High-contrast imaging studies of debris disks have revealed a significant diversity in their morphologies, including large-scale asymmetries. Theories involving stellar flybys, an external source of gravitational disturbance, have offered a plausible explanation for the origin of these morphological variations. Our study is an experiment to gain empirical evidence that has been lacking from such theories. We explore this paradigm by using astrometric and radial velocity measurements from the Gaia DR2 and ground-based observations to trace the trajectories of 625 stars in the Sco-Cen OB association from 5 Myr in the past to 2 Myr in the future. We identified 119 stars that had at least one past flyby event occurring within one Hill radius, and 23 of these experienced flybys within 0.5 Hill radii. We found no evidence of a significant correlation between the presence of flyby events and infrared excess detections, although the sample is not uniformly sensitive to infrared excess emission. Ten stars that had past flyby events host resolved circumstellar disks that appear relatively symmetric in the existing data except for the circumbinary disk surrounding HD 106906. We determined the trajectory and relative velocity of each of these flyby events and compared these to the geometry of the spatially resolved disks. Future work is needed to measure the kinematics of lower-mass stars and to improve sensitivity to circumstellar disks for the entire sample.

Published: April 2022

We perform a detailed characterization of the planetary system orbiting the bright, nearby M dwarf Gliese 411 using radial velocities gathered by APF, HIRES, SOPHIE, and CARMENES. We confirm the presence of a signal with a period near 2900 days that has been disputed as either a planet or a long-period stellar magnetic cycle. An analysis of activity metrics including the H

indices supports the interpretation that the signal corresponds to a Neptune-like planet, GJ 411 c. An additional signal near 215 days was previously dismissed as an instrumental systematic, but we find that a planetary origin cannot be ruled out. With a semimajor axis of 0.5142 ± 0.0042 au, this candidate’s orbit falls between those of its companions and is located beyond the outer edge of the system’s habitable zone (determined using the moist greenhouse and maximum greenhouse limits in Kopparapu et al. 2013). It has a minimum mass of 3.89 ± 0.84 M
⊕, giving a radial-velocity amplitude of 0.81 ± 0.18 m s−1. If confirmed, this would be one of the lowest-amplitude planet detections from any of these four instruments. Our analysis of the joint radial-velocity data set also provides tighter constraints on the orbital parameters for the previously known planets. Photometric data from TESS do not show any signs of a transit event. However, the outermost planet and candidate are prime targets for future direct imaging missions, and GJ 411 c may be detectable via astrometry.
Stable Hydrogen-burning Limits in Rapidly Rotating Very Low Mass Objects
Authors: Chowdhury Shaswata , Banerjee Pritam , Garain Debojyoti , Sarkar Tapobrata
Published: April 2022

We present novel effects of uniform rapid stellar rotation on the minimum mass of stable hydrogen burning in very low mass stars, using an analytic model and relaxing the assumption of spherical symmetry. We obtain an analytic formula for the minimum mass of hydrogen burning as a function of the angular speed of stellar rotation. Further, we show the existence of a maximum mass of stable hydrogen burning in such stars, which is purely an artifact of rapid rotation. The existence of this extremum in mass results in a minimum admissible value of the stellar rotation period of ∼22 minutes, below which a very low mass object does not reach the main sequence, within the ambit of our model. For a given angular speed, we predict a mass range beyond which such an object will not evolve into a main-sequence star.

Published: April 2022

The immense power of gamma-ray bursts (GRBs) makes them ideal probes of the early universe. By using absorption lines in the afterglows of high-redshift GRBs, astronomers can study the evolution of metals in the early universe. With an understanding of the nature of GRB progenitors, the rate and properties of GRBs observed at high redshift can probe the star formation history and the initial mass function of stars at high redshift. This paper presents a detailed study of the dependence on metallicity and mass of the properties of long-duration GRBs under the black hole accretion disk paradigm to predict the evolution of these properties with redshift. These models are calibrated on the current GRB observations and then used to make predictions for new observations and new missions (e.g., the proposed Gamow mission) studying high-redshift GRBs.
Constraints on r-modes and Mountains on Millisecond Neutron Stars in Binary Systems

Published: April 2022

Continuous gravitational waves are nearly monochromatic signals emitted by asymmetries in rotating neutron stars. These signals have not yet been detected. Deep all-sky searches for continuous gravitational waves from isolated neutron stars require significant computational expense. Deep searches for neutron stars in binary systems are even more expensive, but these targets are potentially more promising emitters, especially in the hundreds of Hertz region, where ground-based gravitational-wave detectors are most sensitive. We present here an all-sky search for continuous signals with frequency between 300 and 500 Hz, from neutron stars in binary systems with orbital periods between 15 and 60 days and projected semimajor axes between 10 and 40 lt-s. This is the only binary search on Advanced LIGO data that probes this frequency range. Compared to previous results, our search is over an order of magnitude more sensitive. We do not detect any signals, but our results exclude plausible and unexplored neutron star configurations, for example, neutron stars with relative deformations greater than 3 × 10−6 within 1 kpc from Earth and r-mode emission at the level of α ∼ a few 10−4 within the same distance.

Published: April 2022

We analyzed two eclipse observations of the low-density transiting, likely grazing, exoplanet WASP-34b with the Spitzer Space Telescope’s InfraRed Array Camera using two techniques to correct for intrapixel sensitivity variation: Pixel-Level Decorrelation and BiLinearly Interpolated Subpixel Sensitivity. When jointly fitting both light curves, timing results are consistent within 0.7σ between the two models and eclipse depths are consistent within 1.1σ, where the difference is due to photometry methods, not the models themselves. By combining published radial velocity data, amateur and professional transit observations, and our eclipse timings, we improved on measurements of orbital parameters and found an eccentricity consistent with zero (0.0). Atmospheric retrieval, using our Bayesian Atmospheric Radiative Transfer code, shows that the planetary spectrum most resembles a blackbody, with no constraint on molecular abundances or vertical temperature variation. WASP-34b is redder than other warm Jupiters with a similar temperature, hinting at unique chemistry, although further observations are necessary to confirm this.

AIM: In this study, is to evaluate serum level of ligand programmed death-1 (PDL1) in patients with genital endometriosis.

MATERIAL AND METHODS: For PDL-1, cancer antigen 125 (CA 125), interleukin (IL)-6, IL-8, tumor necrosis factor (TNF), and vascular endothelial growth factor (VEGF) determination, venous blood was taken 1 h before surgery and/or treatment. All patients were stratified by the presence or absence of endometriosis according to the American Society of Reproductive Medicine’s Revised Classification of Endometriosis of the American Society of Reproductive Medicine.

RESULTS: Twenty-one patients with endometriosis participated in the study. The PDL-1 level an experienced group was 55.32 ng/ml (interquartile range [IQR] 34.53–76.20); in the control group was 19.72 ng/ml (IQR 14.72–24.78), which was a statistically significant decrease (p < 0.001). A significant increase in CA125 31.87 (IQR 15.43–36.96) was detected (p < 0.001). In the experimental group, all pro-inflammatory cytokines were elevated (IL-6, IL-8, and TNF, p < 0.013; <0.001; and <0.001) and almost twice increased VEGF 243.44 (IQR 194.56–328.07), (p = 0.016). A noticeable correlation was found between the following indicators PDL-1-CA125, PDL-1-IL-8, and PDL-1-TNF, and a moderate correlation was found between PDL-1 and VEFF (p = 0.006).

CONCLUSIONS: The results of the study showed that the levels of PDL-1, CA 125, IL-6, IL-8, TNF, and VEGF were statistically significantly different in the experimental and control groups, and a correlation was also revealed between the levels of PDL-1 and CA125, IL-8 and TNF in patients with genital endometriosis. Therefore, further studies with larger numbers of patients are required.

Innovation as a Management Question
Authors: Allataifeh Haneen Abdallah , Moghavvemi Sedigheh
Published: April 2022

Whilst the need for innovation is imperative, it is not clear how to manage its process. This is due to the lack of consensus on what an innovation process should look like, variations in the contexts at which innovation is examined, as well as the variations in the means of developing those models. The challenge in managing innovation mainly revolves around the stages of search, selection, and implementation. Issues emerge when organizations develop “routines” for these activities and when these core routines become core rigidities that are embedded and built up into structures, processes, and policies. Hence, we have to deal with a dynamic context by reviewing routines and editing, adding, and adapting to them. Despite the need to formalize and routinize the innovation process, the dynamic environment surrounding innovation should not be kept out of the innovation equation. This chapter sheds light on what is called contextual innovation management and the need to adopt an agile approach in managing innovation.
Premature Deindustrialization Risk in Thailand
Authors: Lar Ni , Taguchi Hiroyuki
Published: April 2022

This study investigates the possibility of premature deindustrialization risk in Thailand, where the pressure of globalization and uneven industrial policies remain. This study adopts the latecomer index to materialize premature deindustrialization risk, which is expressed as the downward shift of the manufacturing–income relationship at the earlier level of income. The results of our empirical analysis confirm the presence of premature deindustrialization risk in Thailand’s regions as a result of globalization pressure (represented by China’s entry into the World Trade Organization) and uneven industrial policies conducted by the Thai government. Thus, the current industrial policies of the Thai government should be reconsidered to overcome premature deindustrialization risk in remote regions.

Published: April 2022

Este trabalho estudou algumas características físicas de compósitos de gesso produzidos com a incorporação de resíduos de borracha de pneus. O programa experimental contou com a realização dos seguintes ensaios: densidade de massa (estado fresco e endurecido), resistência à ruptura na flexão, resistência à compressão, resistência à tração na flexão, ultrassom e microscopia eletrônica de varredura (MEV). O teor de incorporação da borracha de pneus foi de 5% e 10% em relação à massa de gesso. Duas diferentes granulometrias de borracha de pneus foram utilizadas: a denominada fina (#0,075 mm) e a grossa (#2,38 mm). Os resultados proporcionaram uma redução no valor da densidade de massa. Identificou-se que a aderência das partículas de borracha na matriz de gesso não é tão boa na granulometria grossa. Esta deficiência de aderência, constatada nos ensaios de MEV, foi responsável pela menor resistência à flexão, à tração na flexão e à compressão nos compósitos de gesso com a granulometria grossa, quando comparados aos resultados dos compósitos com a granulometria fina. Com relação aos ensaios de ultrassom, constatou-se que a borracha de pneus retarda o tempo de propagação do som. Diante do exposto, a viabilidade técnica do estudo foi testada por meio de corpos de prova, onde se mostrou ser eficiente.

Published: April 2022

Developing an accurate means of classifying defects, such as crystal-originated pits, surface-adhered foreign particles, and process-induced defects, using scanning surface inspection systems (SSIS) is of paramount importance because it provides the opportunity to determine the root causes of defects, which is valuable for yield enhancement. This report presents a novel defect classification approach developed by optimizing the linear-based channeling (LBC) and rule-based binning (RBB) algorithms that are applied to a commercially available SSIS (KLA-SP5), in combination with test sample selection including the signature defect patterns associated with the typical crystal growth process. The experimental results demonstrate that defect classification is possible with an accuracy and purity above 80% using the LBC algorithm and 90% using the RBB algorithm.
Design and Numerical Simulation of Color Tunable Laterally Arranged Quantum well Light Emitting Diode with Double Anode Single Cathode
Authors: Djelloul Ahmid , Zahra Hamaizia
Published: April 2022

In this paper, a color-tunable light emitting diode LED with two laterally arranged single quantum wells (SQWs) is designed, and simulated. In this work, III-nitride materials are used. The structure has been numerically investigated using the ATLAS simulation software. The proposed structure has three electrodes. This gives the opportunity to emit violet (420 nm) or green (560 nm) light individually. Furthermore, it can emit simultaneously a mixture of both colors, and at a certain mixture ratio the white light is obtained with chromaticity coordinates ( x = 0.3113, y = 0.3973). The lateral arrangement of the two SQWs reduces the negative effect of photon absorption; which will give good external quantum efficiency (EQE). The structure has a big importance in the application of the solid-state lighting, especially in the white light generation.
The role of neuromodulation to drive neural plasticity in stroke recovery
Authors: Wang Cong
Published: April 2022

Stroke is one of the leading causes of death and adult disability globally, representing one of the highest burdens of disease worldwide. Recent advancements of neuromodulation techniques emerge as promising tools for enhancing stroke recovery, such as transcranial electric stimulation and transcranial magnetic stimulation, which can induce short- and long-term changes of synaptic excitability to restore the impaired functions in stroke patients. The review focuses on discussing the neuroplastic mechanisms of those brain stimulation techniques in stroke rehabilitation, also including some new options for neuromodulation which have great potential in stroke rehabilitation, such as optogenetic stimulation and environmental stimulation. In general, these techniques allow the excitation and synchronization of the neural activity after stroke, which could potentially induce long-term potentiation. As a result, the neuroplastic effect can lead to better functional connection in the brain network in assisting stroke recovery. Future directions include the clarification of the pathways of synaptic plasticity in the whole brain network following neuromodulation after stroke, and investigation of the different roles of distinctive cell populations in neural plasticity enhancement. Additional studies are essential for developing standard protocols in neuromodulation based on a better understanding of the molecular and cellular processes for the ultimate optimization of clinical efficacy.
Application of repetitive peripheral magnetic stimulation for recovery of motor function after stroke based on neuromodulation
Authors: Pan Jia-Xin , Jia Yan-Bing , Liu Hao
Published: April 2022

Repetitive peripheral magnetic stimulation (rPMS) is a non-invasive and painless approach that can penetrate deeper structures to improve motor function in people with physical impairment due to stroke. A review of available literature was undertaken to discuss the potential mechanisms of rPMS-based neuromodulation and the application of rPMS in the recovery of motor function (e.g., muscle strength, spasticity, motor control and joint mobility, glenohumeral subluxation) after stroke. Issues of concern about parameters and safety of rPMS were also overviewed. Existing evidence has shown that suprathreshold rPMS can be a potential intervention for motor recovery in patients with stroke because of its neuromodulatory effects. However, the rPMS parameters employed by each research team are highly variable for specific lesions. Thus, more high-quality studies on the optimal rPMS protocols for different impairments are warranted in the future.

Published: April 2022

The traditional Chinese herb, Moschus (also called She Xiang in Chinese), is used to accelerate the rehabilitation of Bell's palsy (BP) through acupoint sticking therapy in China. However, the mechanism of its effect is not clear. In this study, we explored the pharmacological mechanism using bioinformatics analysis. We identified 59 active ingredients in Moschus using the Traditional Chinese Medicine Integrated Database, including 17-beta-estradiol, testosterone, and 2,6-decamethylene pyridine. In total, 837 differently expressed genes were identified in blood of BP patients by RNA sequencing. Finally, 33 proteins were identified with overlapping predictions by the Comparative Toxicogenomics Database and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine. Proteins of interest were closely associated with 406 Gene Ontology biological processes and 4 pathways. The hub proteins in the protein–protein interaction network were FOS, JUN, proopiomelanocortin, and G protein-coupled estrogen receptor 1. A pharmacology network was constructed with 15 active components of Moschus, 33 protein targets and four pathways. The docking model of androst-4-ene-3,17-dione and FOS-JUN complexes was predicted and constructed. The results indicated testosterone as an effective component of Moschus that may enhance BP rehabilitation by targeting FUN and the mitogen-activated protein kinase and cyclic adenosine monophosphate signaling pathways, and that docking of androst-4-ene-3,17-dione and FOS-JUN complexes might play a critical role. The findings provide a direction for future research to verify the key targets of Moschus in the treatment of BP and an application prospect in the field of facial nerve rehabilitation.

Published: April 2022

Beckwith-Wiedemann syndrome (BWS) is a complex overgrowth syndrome. Affected children require surgeries for various reasons such as correction of macroglossia, abdominal wall defects, cleft palate or neoplasms. Anaesthesiologists often face problems in the form of a difficult airway, associated congenital heart disease causing haemodynamic compromise and hypoglycaemia, especially during the neonatal period. We discuss the management of a child with BWS scheduled to undergo tongue reduction surgery for macroglossia.
Pathophysiology and rehabilitation management of exercise intolerance in COVID-19 patients
Authors: Nazir Arnengsih , Hasri Indra Putera
Published: April 2022

OBJECTIVE:

This review aimed to explore the pathophysiology and rehabilitation management of exercise intolerance in COVID-19 patients.

METHODS:

We reviewed articles published in 2019-2021 using PubMed, Google Scholar, and CINAHL databases as an electronic database. Data obtained were pathophysiology and rehabilitation management of exercise intolerance in COVID-19 survivors. Types of the article were original articles and systematic or narrative reviews, both published and preprint articles. Articles that were written in English and freely accessible in pdf or HTML format were included.

RESULTS:

There were 28 articles eligible for this review. Pathophysiology, rehabilitation management, and both pathophysiology and rehabilitation management were explained in 7, 24, and 4 articles, consecutively.

DISCUSSION:

Exercise intolerance is caused by some pathological processes in the respiratory, cardiovascular, and musculoskeletal systems as a result of systemic inflammation. Fatigue and shortness of breath during the activity were the most common symptom in the early phase of COVID-19 and persisted until the follow-up phase. Hospital admission, especially prolonged use of ventilators and immobilization worsen functional impairment resulting in persistent symptoms. Rehabilitation management begins with a functional assessment consisting of symptom assessment and physical examination of the body systems affected. The goals of rehabilitation management are to increase functional capacity, reduce symptoms, improve the ability to perform daily activities, facilitate social reintegration, and improve quality of life. Exercise is an effective intervention to reach these goals. Several studies recommend breathing, and aerobic exercises, as well as resistance exercises for peripheral and respiratory muscles, to improve symptoms and increase functional capacity.
