Published: December 2020

Abstract
Effective communication is the key to the learning process for educators. Strong motivation is needed, especially during the Covid-19 pandemic. Webinars are a good medium for motivators to convey motivation and communication solutions for educators. To map the interests of the webinar participants, a Web Geographic Information System (WebGIS) was built. Online registration is spread through social media networks so that there are 859 participants spread across Indonesia. The first largest was obtained by West Sumatra Province with 21%, East Java Province 16.4%, and West Java Province 10%. Participants were dominated by teachers 48% and students 21.7%. With the presence of information on areas, numbers, and percentages visually through the WebGIS application, universities, institutions or stakeholders can formulate policies and planning programs to improve the quality of teaching and learning through communication and learning motivation, both for teachers and students.

Abstract
The production of activated carbon from the cacao (Theobroma cacao) skin waste was investigated to be used as a super capacitor electrode. This study was conducted in order to obtain the characteristics of the activated carbon electrodes of cacao skins. Activated carbon electrodes were made by a combination of chemical and physical activation methods. Samples were pre-carbonized at 250°C for 2.5 hours, whereas chemical activation was performed using KOH activators of 0.3M and 0.4M, with physical activation temperatures of 700°C, and the particle size of the activated carbon used is smaller than 38 µm. Then it was characterized by X-ray diffraction (XRD), the CiklicVoltammetric (CV) method, and Scanning Electron Microscopy (SEM). Hence, the analysis was carried out on the specific dimensions, density and capacitance. It was found that the mass, diameter, thickness, and density of the electrodes have decreased, and the specific capacitance of the electrodes has increased along with the increase in KOH concentration from 0.3 M to 0.4 M. The specific capacitance value at a concentration of 0.3 M was 90.2 F/gr with a density of 0.850gr/cm3 and a concentration of 0.4 M was 140.2 F/gr with a density of 0.802 gr/cm3. The X-ray diffraction curve data showed that the value of Lc and the lattice distance (d002) of C0.4 samples was smaller than the C0.3 sample. From the obtained results, the surface area of the C0.4 sample was greater than the C0.3 sample. It was clear that the chemical activation of 0.4M produces electrodes with better performance than 0.3M.

Abstract
This study aims to investigate the influence of shot penning on fatigue crack growth rate of chemical milling product Al 2524-T3 which have been stretched. This alloys were stretched beyond yield stress, namely 1%, 3% and 5% of each, and then performed chemical milling process of one side. The etching used in chemical milling process were NaOH+Na2S+H2O solutions with certain concentration. The surface was performed shot penning process with varying intensity of 0.03 A, 0.05 A and 0.07 A, respectively. These material were then tested its crack growth rate. The crack growth rate tests were performed under 20% stress level, stress ratio of 0.3 and at frequency 7-13 Hz. The average of crack propagation data against the cycle number were processed using an incremental method, in accordance with ASTM E647 standard, to obtain crack growth rate curve (da/dN vs. ΔK). The results show that the increase of shot penning intensity has no significant effect on the fatigue life, with the growth average of 4,5%. The highest increase occurred at the shot intensity of 0.03 A, 0.2 times its chemical milling, while the lowest decrease occurred at the shot intensity of 0.07A, 0.012 times its chemical milling. The crack retardation effect at the beginning of the crack plays a role in reducing the crack propagation rate.

Abstract
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals produced by this dark matter strongly motivate the development of new, ultra-sensitive detector technologies. Paradigmatic advances in the control and readout of massive mechanical systems, in both the classical and quantum regimes, have enabled unprecedented levels of sensitivity. In this white paper, we outline recent ideas in the potential use of a range of solid-state mechanical sensing technologies to aid in the search for dark matter in a number of energy scales and with a variety of coupling mechanisms.
New results by low momentum approximation from relativistic quantum mechanics equations and suggestion of experiments
Authors: Wang Huai-Yu 
Published: December 2020

Abstract
A fundamental belief is that the formulism of relativistic quantum mechanics equations (RQMEs) should remain in low momentum motion. However, it is found that some formulas from RQMEs were lost in Schrödinger equation. For example, a free relativistic particle has positive and negative energy branches. The former includes positive kinetic energy (PKE) and the latter negative kinetic energy (NKE). The latter should be treated on an equal footing as the former. Nevertheless, from Schrödinger equation, a free particle can have only PKE. Starting from RQMEs and taking low momentum approximation, we derive NKE Schrödinger equation which is for the cases that free particles have NKE. Thus negative energy branch of RQMEs can be retained in low momentum motion. We point out a fact that whether Schrödinger equation is applicable in a region where a particle’s energy E is less than potential V, E < V, has never been quantitatively verified. In such a region NKE Schrödinger equation should be employed. With the help of NKE Schrödinger equation, the lost formulas are recovered. The so-called difficulty of negative probability of Klein–Gordon equation for free particles is solved. A PKE (NKE) particle can have stationary motion only when it is subject to an attractive (repulsive) potential, which is determined by Virial theorem. Two NKE electrons in a potential can constitute a stable system, a new kind of possible mechanism for electron paring. The whole discussion stems from RQMEs with no any new postulation. Experiments are suggested, which may confirm that there are indeed NKE electrons.

Published: December 2020

Abstract
The present work aims to develop an automated solution for analysis of dimple tensile fracture surfaces. An image processing based technique has been proposed to extract the voids from the fractographic images of dimple fracture surfaces and also to analyse the void features. A two-stage process has been developed to extract the closed contour of the voids. At the first stage a global thresholding is followed by a sequence of processing, like thinning and morphological closing. In the second stage refinement process has been carried out on the large voids based on local characteristics. The proposed technique has been applied on the scanning electron fractographs of tensile fracture surfaces obtained by tensile testing of austenitic stainless steel at four different strain rates. It has been found that the size and density of extracted voids bear systematic relationship with tensile properties of the investigated steel. The average circular diameter with yield strength and tensile strength follows linear relationship. The number density of large voids is found to decrease with increase of strain rate and it also decreases with increase of average circular diameter in a linear manner. Similar nature of variation of tensile ductility has been observed both with strain rate and average circular diameter.
On biases of attention in scientific discovery

Published: December 2020

ABSTRACT

Summary
How do nuances of scientists’ attention influence what they discover? We pursue an understanding of the influences of patterns of attention on discovery with a case study about confirmations of protein–protein interactions over time. We find that modeling and accounting for attention can help us to recognize and interpret biases in large-scale and widely used databases of confirmed interactions and to better understand missing data and unknowns. Additionally, we present an analysis of how awareness of patterns of attention and use of debiasing techniques can foster earlier discoveries.

Abstract
Accumulating evidence shows that auditory cortex (AC) of humans, and other primates, is involved in more complex cognitive processes than feature segregation only, which are shaped by experience-dependent plasticity and thus likely show substantial individual variability. However, thus far, individual variability of ACs has been considered a methodological impediment rather than a phenomenon of theoretical importance. Here, we examined the variability of ACs using intrinsic functional connectivity patterns in humans and macaques. Our results demonstrate that in humans, interindividual variability is greater near the nonprimary than primary ACs, indicating that variability dramatically increases across the processing hierarchy. ACs are also more variable than comparable visual areas and show higher variability in the left than in the right hemisphere, which may be related to the left lateralization of auditory-related functions such as language. Intriguingly, remarkably similar modality differences and lateralization of variability were also observed in macaques. These connectivity-based findings are consistent with a confirmatory task-based functional magnetic resonance imaging analysis. The quantification of variability in auditory function, and the similar findings in both humans and macaques, will have strong implications for understanding the evolution of advanced auditory functions in humans.

Abstract
Essential genes are key elements for organisms to maintain their living. Building databases that store essential genes in the form of homologous clusters, rather than storing them as a singleton, can provide more enlightening information such as the general essentiality of homologous genes in multiple organisms. In 2013, the first database to store prokaryotic essential genes in clusters, CEG (Clusters of Essential Genes), was constructed. Afterward, the amount of available data for essential genes increased by a factor &gt;3 since the last revision. Herein, we updated CEG to version 2, including more prokaryotic essential genes (from 16 gene datasets to 29 gene datasets) and newly added eukaryotic essential genes (nine species), specifically the human essential genes of 12 cancer cell lines. For prokaryotes, information associated with drug targets, such as protein structure, ligand–protein interaction, virulence factor and matched drugs, is also provided. Finally, we provided the service of essential gene prediction for both prokaryotes and eukaryotes. We hope our updated database will benefit more researchers in drug targets and evolutionary genomics.

Abstract

Aims
Catheter ablation of paroxysmal atrial fibrillation (AF) reduces AF recurrence, AF burden, and improves quality of life. Data on clinical and procedural predictors of arrhythmia recurrence are scarce and are flawed by the high rate of pulmonary vein reconnection evidenced during repeat procedures after pulmonary vein isolation (PVI). In this study, we identified clinical and procedural predictors for AF recurrence 1 year after CLOSE-guided PVI, as this strategy has been associated with an increased PVI durability.

Methods and results
Patients with paroxysmal AF, who received CLOSE-guided PVI and who participated in a prospective trial in our centre, were included in this study. Uni- and multivariate models were plotted to find clinical and procedural predictors for AF recurrence within 1 year. Three hundred twenty-five patients with a mean age of 63 years (CHA2DS2VASc 1 [1–3], left atrium diameter 41 ± 6 mm) were included. About 60.9% were male individuals. After 1 year, AF recurrence occurred in 10.5% of patients. In a binary logistic regression analysis, the diagnosis-to-ablation time (DAT) was found to be the strongest predictor of AF recurrence (P = 0.011). Diagnosis-to-ablation time ≥1 year was associated with a nearly two-fold increased risk for developing AF recurrence.

Conclusion
The DAT is the most important predictor of arrhythmia recurrence in low-risk patients treated with durable pulmonary vein isolation for paroxysmal AF. Whether reducing the DAT could improve long-term outcomes should be investigated in another trial.
The role of work in gender identity, stress and health in low-income, middle-aged African-American men
Authors: Robinson Dean , Valdez Luis , Scott Lamont , Buchanan David 
Published: December 2020

SummaryAlthough progress has been made in reducing disparities in life expectancy, addressing the persistence of health inequities by race remains a high priority for public health professionals. The purpose of this research was to refine a minority stress model (MSM) by identifying previously unrecognized factors contributing to stress and chronic disease health disparities among low-income middle-aged African-American men. Using a Community-Based Participatory Research approach, we conducted semi-structured individual health interviews with 42 low-income middle-aged African-American men in a mid-size New England city. The interviews focused on the participants’ perceptions of the causes of health disparities. Four major themes emerged from the analysis: the positive aspects of work, both financial and symbolic; and the negative repercussions of not working, both financial and symbolic in terms of a sense of self-respect. On an instrumental level, working men can support their family, be physically active and find social support. Symbolically, work provides a positive sense of identity as a man; it offers both social- and self-respect; it provides discipline and a sense of gratitude. Conversely, the lack of work is a significant source of stress, stemming both from the inability to support one’s family and from having nothing to do, which lead to depression, low self-esteem, suicidal ideation and anger. With no perceived viable routes to socially approved roles, many low-income men of color succumb to internalizing a negative identity. This research demonstrates a clear link between structural problems with the US economy and harms to sense of identity among low-income, middle-aged African-American men.
A voice-based annotation system for collaborative computer-aided design

Published: December 2020

AbstractIn this paper, we describe a voice-based interaction mechanism to annotate 3D models directly from a computer-aided design (CAD) modeling environment. The audio signal is captured and automatically transcribed to a textual 3D note, which is attached to the geometry and made available to other product information and business processes across the enterprise via a product data management system. Our approach provides a more natural and intuitive method to capture design and engineering knowledge that is particularly effective when large amounts of information need to be communicated. We discuss the rationale of the software architecture and the value of this modality for capturing knowledge in a collaborative engineering context. Finally, we examine the results of an experiment to validate our proposal. Our results show that 3D annotations are an effective mechanism to communicate design knowledge, which suggests the need for further developments in the areas of multimodal interaction methods and interfaces for CAD and collaborative tools.

Published: December 2020

Abstract
Neoscytalidium dimidiatum is a plant pathogen, but can also cause onychomycosis. We compared clinical and epidemiological data of cases of onychomycosis caused by N. dimidiatum and Trichophyton rubrum. We also evaluated the in vitro antifungal susceptibility of N. dimidiatum clinical isolates. It was not possible to establish any statistical differences between groups, except the place of residence and the number of affected nails. The results suggest that onychomycosis caused by N. dimidiatum is clinically similar to that caused by T. rubrum; besides, N. dimidiatum has been shown to have low sensitivity to itraconazole, but high to terbinafine.
Spectroscopic classification, variability, and SED of the Fermi-detected CSS 3C 286: the radio-loudest NLS1 galaxy?
Authors: Yao Su , Komossa S 
Published: December 2020

ABSTRACT
3C 286 is a well-known calibrator source in radio astronomy. It is also one of very few compact steep-spectrum (CSS) sources detected in γ-rays. Here, we perform a detailed spectroscopic and variability analysis and present the first quasi-simultaneous optical to X-ray spectral energy distribution (SED) in order to reveal physical mechanisms that dominate its emission at different wavelengths, and arrive at a reliable optical source classification. The first main result of our study reveals several pitfalls when applying simple broad- or narrow-line Seyfert 1 (BLS1 or NLS1) classification criteria that only look at the [O iii]–Hβ complex. [O iii] and Hβ can be dominated by the same outflow components, in which case full width at half-maximum (Hβ) is no reliable classification criterion, and extinction by intrinsic or intervening material can make the highest velocity Hβ component undetectable. After careful combination of all information from ultraviolet (UV)–optical spectra along with multiwavelength data, we confirm that 3C 286 can be classified as NLS1 galaxy, with line properties and supermassive black hole mass (of order 108 M⊙ and accreting near the Eddington limit) close to the BLS1 regime, making it an important borderline object. The quasi-simultaneous SED taken with Swift shows a sharp rise in the optical–UV, implying the presence of a strong accretion-disc component with extreme UV excess, consistent with emission-line diagnostics. Finally, we report the discovery of X-ray variability of 3C 286, plausibly dominated by jet emission, and variable by at least a factor of ∼4. This result suggests to exercise caution when using 3C 286 as radio calibrator in high-resolution radio very long baseline interferometry observations.
