Biases in Estimates of Black Hole Kicks from the Spin Distribution of Binary Black Holes
Authors: Stevenson Simon
Published: February 2022

A population of more than 50 binary black hole mergers has now been observed by the LIGO and Virgo gravitational-wave observatories. While neutron stars are known to have large velocities associated with impulsive kicks imparted to them at birth in supernovae, whether black holes receive similar kicks, and of what magnitude, remains an open question. Recently, Callister et al. analyzed the binary black hole population under the hypothesis that they were all formed through isolated binary evolution and claimed that large black hole kicks (greater than 260 km s−1 at 99% confidence) were required for the spin distribution of merging binary black holes to match observations. Here we highlight that a key assumption made by Callister et al.—that all secondary black holes can be tidally spun up—is not motivated by physical models and may lead to a bias in their estimate of the magnitudes of black hole kicks. We make only minor changes to the Callister et al. model, accounting for a population of wider merging binaries where tidal synchronization is ineffective. We show that this naturally produces a bimodal spin distribution for secondary black holes and that the spin–orbit misalignments observed in the binary black hole population can be explained by more typical black hole kicks of order 100 km s−1, consistent with kicks inferred from Galactic X-ray binaries containing black holes. We conclude that the majority of the binary black hole population is consistent with forming through isolated binary evolution.

Introduction: Real time quantitative PCR is the gold standard for detection of SARS-CoV-2 which is specific, sensitive, and simple quantitative. The target of RT-qPCR is to assess the expression level of the SARS-CoV-2 gene through cycle threshold values (CT-value). The purpose of this study was to analyze the association of the level of SARS-CoV-2 gene expression and the severity of COVID-19 in patients hospitalized. Method: This research is an analytic observational study with cross sectional method. While the research sample was taken using a consecutive sampling technique from the Medical Records of Sumedang Hospital and Cideres Hospital, West Java, Indonesia from December 2020 to March 2021. Patient parameters include analysis of age, sex, comorbidity, and disease severity. The severity of the patient is classified based on complaints and oxygen saturation. The expression level of the SARS-CoV-2 N gene and E gene were assessed by calculating the relative quantification by comparing the expression of the E and N gene with the expression of the internal control gene by Livak formula (2-ΔΔCT Formula). Result: The Spearman correlation test showed that there was a relationship between the expression of SARS-CoV-2 genes E and N genes with the severity of COVID-19 patients (with r=0.374 and p<0.0001) and (with r=0.452 and p<0.0001). Conclusions:  There is an correlation between the level of expression of genes E and gene N with the severity of patients.

Authors: Tasijawa Fandro Armando , Siagian Indah
Published: February 2022

BACKGROUND: Resilience can help adolescents to have positive adaptations in dealing with difficulties, stress, and trauma, as well as preventing mental disorders. School-based resilience improvement programs have been implemented internationally. However, there has been no specific review to examine the effectiveness of the application of resilience programs in adolescents.

AIM: This review aimed to analyze the effectiveness of school-based interventions to increase resilience in adolescents.

METHODS: Search articles using three electronic databases, namely CINAHL Ebsco, PubMed, and ProQuest. The keywords used are “resilience or resilient” AND “adolescents or teenagers or young adults” AND “school-based intervention or classroom-based intervention or teacher implemented.” There are 1206 research articles from 2014 to 2020, but only nine randomized controlled trials (RCT) studies match the inclusion criteria for analysis.

RESULTS: Findings show that five school-based intervention programs have a significant effect on adolescent resilience levels, namely: enhancing resiliency among students experiencing-stress-prosocial, mindfulness training with learning to BREATH (mindfulness-based programs stress reduction), resilience and coping intervention (RCI), and girls first resilience curriculum. The shortest program duration is RCI, 3 weeks, while the most extended time is Girls first for 5 months. The duration of the program had no significant effect on increasing resilience.

CONCLUSION: These findings encourage further research and development of school-based intervention programs to increase resilience in adolescents, especially in developing countries such as Indonesia.

This study analyses the façades of a white concrete building located in Cádiz (Spain). Numerous sections of the concrete cladding on the façades have become detached and there are clear signs of reinforcement corrosion. For the purposes of this study, the arrangement of the reinforcement was evaluated by georadar (GPR). Cylindrical concrete cores measuring 10 cm in diameter by 15–18 cm in depth were extracted and their carbonation front was evaluated. Samples were characterized by physical properties determination; chemical and mineralogical analysis and the chloride penetration profiles.

According to the results obtained, the concrete used can be considered permeable and porous (16.5–19.7%). Only two sampling points fulfilled the minimum reinforcement coating requirements for this type of environmental exposure, in accordance with current Spanish legislation. The carbonation fronts have reached the reinforcements, causing their depassivation. Depending on the orientation of the façade, the penetration of chlorides from marine spray was observed with a maximum value of 0.250% by weight of cement, without reaching the limit states of durability.

Pandemic due to SARS-CoV-2 (COVID-19) has affected to world in several aspects: high number of confirmed cases, high number of deaths, low economic growth, among others. Understanding of spatio-temporal dynamics of the virus is helpful and necessary for decision making, for instance to decide where, whether and how, non-pharmaceutical intervention policies are to be applied. This point has not been properly addressed in literature since typical strategies do not consider marked differences on the epidemic spread across country or large territory. Those strategies assume similarities and apply similar interventions instead. This work is focused on posing a methodology where spatio-temporal epidemic dynamics is captured by means of dividing a territory in time-varying epidemic regions, according to geographical closeness and infection level. In addition, a novel Lagrangian-SEIR-based model is posed for describing the dynamic within and between those regions. The capabilities of this methodology for identifying local outbreaks and reproducing the epidemic curve are discussed for the case of COVID-19 epidemic in Jalisco state (Mexico). The contagions from July 31, 2020 to March 31, 2021 are analyzed, with monthly adjustments, and the estimates obtained at the level of the epidemic regions present satisfactory results since Relative Root Mean Squared Error RRMSE is below 15% in most of regions, and at the level of the whole state outstanding with RRMSE below 5%.

Real-time network inspection applications face a threat of vulnerability as high-speed networks continue to expand. For companies and ISPs, real-time traffic classification is an issue. The classifier monitor is made up of three modules: Capturing_of_Packets (CoP) and pre-processing, Reconciliation_of_Flow (RoF), and categorization of Machine Learning (ML). Based on parallel processing along with well-defined interfacing of data, the modules are framed, allowing each module to be modified and upgraded separately. The Reconciliation_of_Flow (RoF) mechanism becomes the output bottleneck in this pipeline. In this implementation, an optimal reconciliation process was used, resulting in an average delivery time of 0.62 seconds. In order to verify our method, we equated the results of the AdaBoost Ensemble Learning Algorithm (ABELA), Naive Bayes (NB), Decision Tree (DT), K-Nearest Neighbor (KNN), and Flexible Naive Bayes (FNB) in the classification module. The architectural design of the run time CSNTA categorization (flow-based) scheme is presented in this paper.

Published: February 2022

The life and safety issues of Li metal electrodes seriously hinder its application. In order to solve this problem, MXene protected Li electrode has been prepared. Due to the formation of MXene-Ti3C2Tx interface layer, not only the uneven deposition of Li could be alleviated, but also the unstable formation of solid electrolyte interphase can be suppressed. Thus, the MXene-Ti3C2Tx@Li electrodes have exhibited excellent cycling stability. The cycling performance of MXene-Ti3C2Tx@Li electrodes have been proved by symmetric cells, which exhibit relatively stable voltage plateau and a small voltage hysteresis even after 29000 min for stripping/plating cycling (about 230 cycles) under current density of 5 A cm-1 and specific capacity of 5 Ah cm-1. Overall, this study demonstrates MXenes as a critical enabler to realize high-performance Li metal batteries.

Authors: Zhang Yue , Li Tao , Tang Shi Yu , Xie Xin Yue , Liang Ru Zeng , Chu Xiao Xiao
Published: February 2022

Increasing demands of microwave absorbents require new approaches to enhance the absorbing performance. Metal−organic frameworks (MOFs) could be developed as effective absorbers owing to their outstanding features including intrinsic porosity and high specific area. Herein, novel nanostructured Co-MOF-74 composites have been successfully fabricated via a simple solvothermal method. Excellent absorption performance was achieved for the composite with a minimum reflection loss (RL) of −25.5 dB at 2.5 mm and a broad absorption bandwidth (RL < −10 dB) of 6.7 GHz. Such absorber could be developed as lightweight and high-efficiency absorbing materials, and this work provides inspiration for the design of advanced absorbers with strong dissipation capacity and broad effective bandwidth.

Authors: Zhang Li Xin , Sun Sheng Liu , Huang Wen Qi , Chen Zhen Yu , Wang Hao , Zhang Chun Qian
Published: February 2022

Group-IV SiGeSn ternary alloy is a hot spot in the field of fabricating high-efficient Si-based light source due to its large lattice constant and bandgap variation range. However, due to the high cost and low speed of experimental and computational research, it is difficult to obtain their lattice constants comprehensively and quickly. Machine learning prediction based on statistics is an advanced method to solve this problem. In this paper, based on the existing data of group IV alloys, three machine learning methods such as Random Forest (RF), Support Vector Regression (SVR) and Gradient Boosting Decision Tree (GBDT) have been built to predict the lattice constants of SiGeSn. Firstly, the lattice constants of Group-IV alloys are collected to construct data set; Then, the data set are used to train the machine learning models which describe the quantitative relationship between concentrations and lattice constants; Finally, the prediction performance of these models are compared with each other, and the concentrations with appropriate lattice constants are predicted. The results show the comprehensive performance of SVR model is better than the other two, which means the SVR model can be used to directly predict the lattice constants of SiGeSn.

Authors: Ohar Viktor , Denayer Julien
Published: February 2022

Rugose corals are described from the lower Viséan of the Donets Basin. The new coral Dorlodotidae fam. nov. and the species Cyathoclisia sukhensis sp. nov. are here introduced and the presence of the genera Amygdalophyllum and Ceriodotia are established for the first time in the Donets Basin. The priority of the generic name Protolonsdaleia over Eolithostrotionella is discussed. The lower Viséan rugose coral assemblage of the Donets Basin differs from those of the upper Tournaisian and upper Viséan. Global and regional events may have led to abrupt changes in sedimentation conditions at the end of the Tournaisian time and at the beginning of the late Viséan. The colonial rugose corals Siphonodendron, Dorlodotia, Protolonsdaleia and Ceriodotia appear in the early Viséan of the Donets Basin as in many other regions of Eurasia. The similarity of the lower Viséan coral assemblage of the Donets Basin with that of the Western Paleotethys is noted but at the same time, there are significant differences with the regions of the Eastern Paleotethys. This is due to the presence of a possible paleogeographic barrier located to the eastern part of Laurussia hindering the migration of corals.Keywords: Mississippian, Viséan, corals, paleobiogeography, Ukraine.

Published: February 2022

In the global vision to promote, safeguard, and maintain the health and safety of the general population and to meet the recommended standards of quality of healthcare offered, it is a must to assess the performance of medical students during their period of training. In the conventional form of medical education, assessment has predominantly been quantitative with teachers being the main stakeholder to carry out an assessment. In addition, personal views and opinion of peers or other stakeholders have also not been given due importance. However, the findings of studies have indicated that the use of mini-peer assessment tool (PAT) has played a significant role in improving the performance of students. In conclusion, the use of peers as assessors is an effective form of teaching–learning and assessment in the field of medical education. Even though there can be some extent of reluctance on the part of students, it is advisable to advocate and implement the use of mini-PAT in the training period.

Guillain–Barré syndrome (GBS) is a disorder of the peripheral nervous system characterized by acute-onset ascendance paresis. We present a patient who was diagnosed as having facial-onset acute inflammatory demyelinating polyneuropathy after being infected with SARS-CoV-2. A 51-year-old man presented to the emergency department with facial diplegia. He then developed bilateral ascendance paralysis. He had noticed that for 1 month, he had smell and taste disturbances. SARS-CoV-2 infection was suspected. Nasopharyngeal swab polymerase chain reaction test was negative, but anti-SARS-CoV-2 antibody was found to be positive. A nerve conduction study showed prolonged motor distal and F wave latencies with decreased motor and sensory compound muscle action potential amplitudes. Lumbar puncture revealed albuminocytologic dissociation. According to the neurologic examination and laboratory findings, the patient was diagnosed as having acute inflammatory demyelinating polyneuropathy. An axonal excitability study revealed fanning in pattern with prolonged refractoriness, which indicates nodal sodium channel disturbances. Facial-onset SARS-CoV-2–related GBS has been rarely reported; however, facial involvement seems to be one of the features of the neurologic findings.

A Review: Trending Clustering Protocols In WSN With Analyzing Their Complexity And Disadvantages
Authors: Kamalpreet Kaur, Naveen Goyal and Deepinder Singh Wadhwa
Published: February 2022

Wireless Sensor Networks are generally consists of various static or mobile sensor nodes that create a
self-organized system in a multi-hop manner. Wireless Sensor Networks are considered as the main
component to analyze the surroundings so as to utilize the sensor data for further processing such as
weather prediction, health related predictions of a patient, traffic control and so forth. In these conditions, the
network’s sensor nodes are estimated to perform individually in the field for a long time, as it is not possible
to recharge or replace the battery of the sensor nodes. Therefore, the depletion of a single sensor node may
affect the processing of the entire network. Due to early energy depletion of the nodes, the concept of Cluster
Head (CH) selection have included.This concept has a major impact on energy utilization of the network.
Several clustering protocols, and optimization techniques are used formaintaining the energy efficiency in
wireless sensor network and few of them are discussed in this work. This paper offers an overviewof the
work that has been done by many authors.

Cloud Computing is a field of computer science in which user can access resources remotely through browser
.Cloud Computing increases the speed of accessing the services in very much less cost without actually
deploy them. It decreases the time from implementing the software to actually deploy it. Cloud Computing
users can access resources on demand. Cloud provides the on demand services, virtualization and open
source. The data owner can stored and access the data from the cloud with the help of cloud service provider.
In the large organizations the data which is stored on the cloud is accessed by the many users of the same
organization. In such a case the problem of inconstancy may arise, because the unauthorized user can
delete or modify the data. If the two persons are accessing the same data at same time, then read-write,
write-read conflicts may arise. In this, I even have designed wireless clump rule with the assistance node
degree, Stability issue, and weight and CH choice. In this work, there is data duplication and data
redundancy problem that I have faced and some other problem are the network life time problem due to the
redundancy and transmission energy is lost, so there is energy consumption problem. Due to these problems
some other problems like scheduling problem.

While the formalized discipline of intimacy work may be newer, the work itself has been happening in formal and informal ways for centuries. A number of intimacy training organizations have popped up around the world to meet the growing demand for qualified intimacy professionals and broader consent education. Theatrical Intimacy Education was founded, in part, to help meet that need. 

All of these organizations have slightly different approaches to intimacy work, organizational structures, and visions for what the intimacy field should be. Those differences are cultural, philosophical, and practical. Diversity of approaches is a good thing for everyone and I genuinely believe that all of the intimacy organizations are doing what they think is best to make the industries we work in a better place. 

The people leading the field are always leveraging power, for better or for worse, and I think we need to be deeply critical about the systems we intentionally or inadvertently introduce or perpetuate. I think the choice to introduce or perpetuate certification and certification-style systems in intimacy work is a major error that is undermining the good work the field is trying to do.

Published: February 2022

In Brazil, where the transport sector is one of the biggest contributors to air pollution in cities, replacing conventional buses with electric vehicles can save lives and positively impact the economy. This is what ImpactAr tool, a technical note and a valuation model, demonstrates. Developed in partnership with the Children’s Investment Fund Foundation (CIFF), ImpactAr provides the magnitude of the variations on the number of fatalities and hospitalizations and the consequent economic and welfare costs related to changes in air pollution levels caused by modifications in the Brazilian urban bus fleets. The methodology can be applied by any city, sector operators, academics and researchers. For São Paulo, Rio de Janeiro, Belo Horizonte and Niterói, spreadsheets are already set up with data for environmental, epidemiological and economic projections. By making the implicit impacts on health and well-being of air pollution visible, ImpactAr can encourage cities to initiate or accelerate the transition from public transport to green fleets.

The purpose of this study was to evaluate some elements of physiology and biochemistry in Nepeta racemosa Lam. in the pedo-climatic conditions of the Moldavian forest steppe. The parameters were quantified under conditions of differentiated fertilisation with three foliar products (KSC 1, KSC 2, and Corona K). Biochemical analysis by GC/MS revealed the highest concentration of the following components: nepetallic acid (Untreat - 54.33%, KSC 1 - 55.50%, KSC 2 - 56.90%, Corona K - 53.77), eucalyptol (Untreat . 9.87%, KSC 1 - 10.70%, KSC 2- 12.80%, Corona K - 10.78%), 3-hydroxy-(4S, 4aS, 7S, 7aS)-dihydronepetalactone (Untreat - 5.87%, KSC 1 - 5.37%, KSC 2 - 4.87, Corona K - 3.67%), and (4aS, 7S, 7aS)-trans, cis-nepetalactone (Untreat - 4.30%, KSC 1 - 5.00%, KSC 2 - 4.20%, Corona K - 5.23%). Polyphenols were present in large quantities in the Corona K variant, with 33.1 mg GA/g dw at the first harvest and 27.88 mg GA/g dw at the second harvest. The highest concentration of flavonoids was identified in the Corona K variant (26.34 mg QE/g dw - first harvest and 56.77 mg QE/g dw - second harvest). The antioxidant activity was between 14.76 and 38.54% at the first harvest, and from 12.18 to 22.95% at the second harvest. Chlorophyll pigments ranged from 13.12-17.68 μg/ml-1 for chlorophyll a, 5.43-9.66 μg/ml-1 for chlorophyll b, and 2.07-3.34 μg/ml-1 for carotenoids. The highest grass production per m2 was achieved in the version fertilised with KSC 1 for both crops, with 986.66 g/m2 for the first harvest and 861.33 g/m2 for the second. Iridoids are a class of substances that are commonly used for pesticide role. The study aims to highlight these substances and determine whether differentiated fertilization influences. The presented data confirm the results in the literature for polyphenols and flavonoids, but also present chemotypic novelties in terms of chemical composition and represent a direction to follow for future research.

A medical clinic to examine the risk factors for some non-communicable disease (NCD)s was held for zoo workers with permission from the management within Pinnawela elephant orphanage (PEO). Resulting information was compared between those who work with (E) and those do not work closely with elephants (NE). The medical staff comprised of 3 doctors, 3 nurses 2 attendants and 2 laborers. A questionnaire was administered as and when each participant zoo worker was examined. Those with health issues requiring further medical attention were referred to the general hospital 8km away.  A total work force in PEO is around 90 and 82 of them participated in the clinic, 22 were from E while 60 were from NE group. Overall body mass index (BMI) of participants indicated 4 participants to be obese, 36 to be overweight and 3 to be underweight, most of them from NE group. Altogether, 18(18/78) had elevated systolic blood pressure out of which 14 (14/82) were from NE. A total of 6 had elevated diastolic blood pressure out of which 5 were from NE group. Vision and hearing appeared not to be serious issues. Alcohol consumption and regular smoking were frequently observed among the NE group. Only one from E and 8 from NE reported some chronic health condition in them. Overall, 74 workers were not found to be having any of the chronic conditions listed (73/82= 91%) out of which vast majority (n=20) were from E group. Food habits, regular exercise and perhaps social aspects may have contributed to the findings. The E group was apparently healthier compared to those in NE perhaps due to their constant exposure to work related regular exercise. Rapid attention must be paid towards NCD situation in zoo workers, if the work force must be maintained healthy.
