Profiling Hungarian K12 teachers based on their techno-pedagogical skills: State of affairs and development possibilities amid COVID-19
Authors: Fekete Imre 
Published: July 2022

Abstract
Covid-19-triggered emergency remote teaching shed light on the discrepancies of the long-desired digital transformation of education. To learn more about Hungarian K12 (primary and secondary) teachers' techno-pedagogical skills, this study aimed to measure how they rate the components of the Technological Pedagogical Content Knowledge (TPACK) framework. The observed mean values gave grounds for clustering Hungarian K12 teachers based on their existing techno-pedagogical skills as well as proposing possible directions for development. It was found that among teachers who participated in the study (N = 216), 20% belong to the group of Beginners, 40% are Independent, and 40% are Advanced users of techno-pedagogical tools and methods. The groups are rather homogenous as gender, age, qualification and teaching experience are not predictors of techno-pedagogical knowledge. Beginners need help on the very operational levels of technology, Independent users transform traditional teaching methods in the online space, while Advanced users plan face-to-face and online classes differently but also include techno-pedagogy in their everyday classroom teaching practices. It was further observed that teachers in all groups are generally motivated in preparing for their online lessons, but the perceived motivation of their learners is much lower, and teachers do not generally consider online teaching effective.

Published: July 2022

Abstract
We have developed a system based on deep learning for the detection and removal of glitches, a special type of noise that is common in the continuous data recorded by the Seismic Experiment for Interior Structure (SEIS) system deployed on Mars during the InSight mission. We first used the existing algorithms to build datasets of glitches and noises that are used to train the detection and removal networks. Then glitch detection was realized by a five-layer convolutional neural network (CNN); glitch removal is fulfilled by subtracting from the raw record a glitch waveform constructed using a deep autoencoder network. The resulting GlitchNet, a combination of our CNN and autoencoder network, delivers better performance for glitch detection and removal in SEIS very broadband records with much higher computational efficiency than existing methods.

Purpose — to study visualized biomarkers before and after navigation laser treatment in patients with diabetic macular edema (DMO) using optical coherence tomography-angiography (OCT-A).Methods. 85 patients (85 eyes) with focal DMO were under observation. The patients were divided into two groups, depending on the method of laser treatment used: group 1 consisted of 50 patients (50 eyes) who underwent navigation sub-threshold laser exposure in micro-pulse and continuous modes with individual selection of energy parameters according to the developed technology (patent RF for invention No. 2752544 of 27.01.2021), in group 2 (35 patients, 35 eyes) laser coagulation was performed according to the type of “modified grid”. The treatment was carried out on the NAVILAS 577S navigation laser system (“OD-OS”, Germany). All patients in both groups underwent high-resolution OCT-A according to the Angio Retina 3×3 mm and HD Angio Retina 6×6 mm protocol. The following biomarkers were evaluated by the OCT-A method: vascular density of the superficial vascular plexus (SCP), deep vascular complex (DCP); the number of microaneurysms and hyperreflective points; the area of the foveal avascular zone, as well as cysts and zones of disorganization of the inner layers of the retina (DRIL), at various times before and after (1, 3 and 6 months) treatment.Results. According to OCT-A, as a result of treatment in group 1, there was an increase in total vascular density from 38.45 ± 0.4 % to 44.85 ± 0.66 % in SCP and from 43.55 ± 0.38 % to 44.85 ± 0.66 % in DCP by 6 months of follow–up. In group 2, the total vascular density in SCP increased from 37.4 ± 0.36 % to 37.85 ± 0.34 %, in DCP from 43.35 ± 0.38 % to 44.05 ± 0.41 %. The number of microaneurysms decreased on average from 12 ± 0.42 to 9 ± 0.3 by 3 months and 7.5 ± 0.26 by 6 months in group 1 and, from 19 ± 0.7 to 15.5 ± 0.6 (3 months) and 13 ± 0.5 (6 months) — in group 2. The number of hyperreflective points decreased in terms of 3 and 6 months in both groups. The area of cysts progressively decreased, and the area of FAZ and DRILS was stable throughout all the follow-up period.Conclusion. OCT-A is a highly informative diagnostic method that allows noninvasively to identify visualized OCT-A biomarkers, as well as to evaluate the effectiveness of navigation laser exposure in patients with diabetic maculopathy with focal diabetic macular edema.

Los planes de acción son instrumentos de planificación que facilitan el proceso de implementación e incorporación de agendas de investigación con plazos de tiempo definidos mediante investigación participativa en las instituciones orientadas a la generación de impacto social. Este documento describe el plan de acción de la Sede El Carmen de Bolívar (SCB) de Agrosavia 2018 -2028 orientado a promover la competitividad y sostenibilidad de este centro de ciencia e incrementar su impacto en su área de influencia: los departamentos de Sucre y Bolívar. Este Plan de Acción empleó una metodología participativa con tres fases principales: el diagnóstico del entorno de la SCB, la identificación de las ventajas competitivas y debilidades del centro, y lineamientos estratégicos integrados en el plan de acción institucional. El diagnóstico de entorno permitió evidenciar que existe una demanda territorial insatisfecha para las áreas de manejo de cosecha y postcosecha. Por otra parte, existe una oferta tecnológica relacionada con material de siembra y mejoramiento genético que los actores regionales no están demandando. Este artículo presenta un portafolio de acciones específicas que confluyen en el propósito de la generación de oferta tecnología (OT) pertinente a los territorios y acorde a las demandas del productor. Los hallazgos descritos en este documento son un insumo para el desarrollo de un nuevo plan de acción para la SCB en el actual escenario postpandemia.

Published: July 2022

<div> Dispute resolution through the judicial process is considered ineffective and efficient, because it is slow and convoluted. This is not in accordance with the basic principles in the judiciary, namely the judiciary is carried out in a simple, fast and low cost way. However, with the establishment of PERMA No. 2 of 2015 concerning Procedures for Settlement of Simple Lawsuits, the settlement of simple lawsuits disputes through Litigation can run more efficiently with all the provisions contained therein, including the elimination of exceptions. This study uses a literature study research method with a normative juridical approach. The data obtained from primary and secondary legal materials were collected using the library method for further analysis to determine the urgency of removing exceptions in PERMA No. 2 of 2015 concerning Procedures for Settlement of Simple Lawsuits. Based on the analysis carried out, the elimination of exceptions in the regulation is in accordance with the principles of simplicity, speed and low cost in court. Where this principle aims to make it easier for people to find the truth without injuring the rights of the parties because the entire process to be carried out has been explained in advance by the judge. In this case, it also avoids procrastination by the parties so that disputes can be resolved more quickly. Eliminating this exception is in line with the goal of maslahah mursalah. Because the purpose of maslahah mursalah with the use of simple, fast and low-cost principles is the same, namely for benefit by providing convenience in seeking the truth.</div><div> </div><div> </div>

Authors: Wallace Maeve E. 
Published: July 2022

Objectives. To estimate the national pregnancy-associated homicide rate in 2020 and to characterize patterns of victimization. Methods. Using a retrospective analysis of the 2020 US national mortality file, I identified all homicides of women who were pregnant or within 1 year of the end of pregnancy. Descriptive statistics characterized these victims, and I calculated annual pregnancy-associated homicide rates (deaths per 100 000 live births) for comparisons with 2018 and 2019. I estimated the added risk conferred by pregnancy in 2020 by comparing the pregnancy-associated homicide rate to homicide in the nonpregnant, nonpostpartum population of females aged 10 to 44 years. Results. There were 5.23 pregnancy-associated homicides per 100 000 live births in 2020, a notable increase from previous years. Rates were highest among adolescents and non-Hispanic Black women. Eighty percent of incidents involved firearms. The risk of homicide was 35% greater for pregnant and postpartum women than for their nonpregnant, nonpostpartum counterparts, who did not experience as large an increase from previous years. Conclusions. Pregnancy-associated homicide substantially increased in 2020. Public Health Implications. Policies to address domestic and community violence against women are urgently needed.

Abstract
The second messenger 3',5'-cyclic adenosine monophosphate (cAMP) regulates many nuclear processes including transcription1,2, pre-mRNA splicing3 and mitosis4. While most functions are attributed to protein kinase A (PKA)5,6, accumulating evidence suggests that not all nuclear cAMP-dependent effects are mediated by this kinase7, implying that other effectors are involved. Here we explore the nuclear roles of Exchange Protein Activated by cAMP 1 (EPAC1). We find that EPAC1 enters the nucleus through the synergy of two aminoacidic domains and there, in response to cAMP, forms reversible biomolecular condensates through liquid-liquid phase separation. This phenomenon depends on intrinsically disordered regions present at its amino-terminus and is independent of PKA. Finally, we demonstrate that nuclear EPAC1 condensates assemble at genomic loci on chromosome 6 and promote the transcription of a histone gene cluster. Collectively, our data reveal an unexpected mechanism through which cAMP contributes to nuclear spatial compartmentalization and promotes the transcription of specific genes.

Authors: Thakur Ekta , Jaglan Naveen 
Published: July 2022

Abstract
This paper presents a Circularly polarized (CP) Ultra-Wideband (UWB) multiple-input-multiple-output (MIMO) antenna with three rejected bands. To produce triple band-notched characteristics, two compact Electromagnetic bandgap cells are placed near the feedline of the planar antenna. A broad Axial ratio bandwidth (ARBW) is obtained by adding a slot and a stub expanded from the ground plane. The ability to produce wide ARBW is an additional feature of the suggested structure. This MIMO antenna has a -10dB bandwidth of 3.1–10.6 GHz and axial ratio bandwidth of 3-10.4 GHz with three-rejected bands at 3.5, 5.5 and 8.2 GHz. Moreover, the suggested structure shows good diversity characteristics properties like an envelope correlation coefficient (ECC) > 0.03, total active reflection coefficient (TARC) > 10 dB, and diversity gain (DG) of approximately 9.99. The considered configuration is fabricated using an FR4 dielectric substrate with a total size of 42.7×55×1.6 mm3.

Abstract
Transfer learning appears to be a potential method for transferring information from general to specialized activities. Unfortunately, experimenting using various transfer learning models does not yield good results. In this paper, we propose the utilization of the Hough transform (HT) to improve modulation format recognition. HT is utilized to estimate points on constellation diagrams patterns with perspective projection. The HT algorithm extracts the raw image feature lines. The feature edges are then translated into Hough space, where line segments are found. The Hough transform is used to project a constellation diagram in another location and extract features from it. Constellation diagrams for eight different modulation formats (2/4/8/16 - PSK and 8/16/32/64 - QAM) are obtained at optical signal-to-noise ratios (OSNRs) ranging from 5 to 30 dB. This model is based on classification, and transfer learning. The obtained results indicate that, even at low OSNR values, the suggested system is capable of blindly recognizing the wireless optical modulation format with a classification accuracy of up to 99%.
Nonlinear increase of the real contact area of PMMA blocks and the related contact model
Authors: Luo Zhijun , Wu Kai , yan shaoze 
Published: July 2022

Abstract

Many experiments have proved the contact models, such as GW model, MB model, however, most of past validations are under light load. In this paper, based on total reflection method, we performed direct measurements of the real contact area between two polymethylmethacrylate (PMMA) blocks under heavy load, and utilized the image processing method to analyze the contact area. The results shows that the real contact area increase with normal load linearly in light load, but non-linearly under heavy load; the number of contact spots increase with load linearly in light load, but also nonlinearly under heavy load, synchronous with the changing of real contact area. We used GW and MB model to predict the experiment result, and found that both models failed to predict the nonlinear stage. Finally, we proposed a revised GW model based on the hypothesis of bulk deformation to predict the non-linear stage.
Nonlinear multi-magnon scattering in artificial spin ice

Published: July 2022

Abstract
Magnons, the quantum-mechanical fundamental excitations of magnetic solids, are bosons whose number does not need to be conserved in scattering processes. Microwave-induced parametric magnon processes, often called Suhl instabilities, have been believed to occur in magnetic thin films only, where quasi-continuous magnon bands exist. Here, we reveal the existence of such nonlinear magnon-magnon scattering processes and their coherence in ensembles of magnetic nanostructures known as artificial spin ice. We find that these systems exhibit effective scattering processes akin to those observed in continuous magnetic thin films. We utilize a combined microwave and microfocused Brillouin light scattering measurement approach to investigate the evolution of their modes. Scattering events occur between discrete bands whose resonant frequencies are determined by each nanomagnet's mode volume and profile. Comparison with numerical simulations reveals that parametric pumping leads to scattering from bulk modes into edge modes. Moreover, our results suggest that tunable directional scattering is possible in these structures.

Published: July 2022

Abstract
A solar air heater is a simple device designed to collect solar radiation for heating applications. Usually, the overall performance of a solar air heater is poor because of the low thermal conductivity of the air. An attempt has been made to improve the performance of the existing solar air heater by producing the local turbulence in the flowfield with the help of a circular cavity that is positioned on the absorber plate. The dimensions and placement of these circular cavities are defined using the three dimensionless parameters: relative cavity depth (Dd); relative crosswise distance (Dc); and relative flow-wise distance (Df) which varied from 0.016 to 0.038, 6–14, and 6 to 14, respectively. The effect of these circular cavities has been analyzed on the hydraulic and thermal performance using numerical simulations which were performed by developing a CFD code on Fluent software. The circular cavities promote the local turbulence in the flowfield which support the vortex generation and results in better heat transfer to the air from the absorber plate. The augmentation of heat increases substantially by 2.57 times at the expanse of 2.3 times increase in pressure at relative cavity depth (Dd); relative crosswise distance (Ds); and relative flow-wise distance (Dl) of 0.038, 10, and 10, respectively. Moreover, the overall performance of the proposed found to be 1.75 times the conventional solar air heater under similar conditions.
