Larmor Electric Field in Symmetric Magnetic Reconnection
Authors: Yi Yongyuan , Zhou Meng , Song Liangjin , Zhong Zhihong , Pang Ye , Deng Xiaohua 
Published: June 2023

Abstract
The Larmor electric field (LEF) was previously suggested as a signature to identify the diffusion region in asymmetry reconnection. Using 2.5D particle-in-cell simulations, we show that the LEF also exists in symmetric reconnection, manifested as a transient structure upstream of the Hall electric field. The LEF emerges during the rapid growth phase of the reconnection rate and has opposite polarity to the Hall field. The half-width of the current sheet spontaneously decreases to the electron scale as the evolution of reconnection, which gives rise to the LEF. The current sheet later thickens to maintain the fast reconnection rate, which causes the disappearance of the LEF. We further find that the magnitude of LEF is sensitive to the initial half-width current sheet, the background plasma temperature and density, the guide-field strength, and the ion–electron mass ratio. Our results provide new insight into the dynamics around the diffusion region. The LEF can help satellites not only locate the diffusion region but also identify the onset phase of reconnection in the magnetotail.
Terrestrial Effects of Nearby Supernovae: Updated Modeling
Authors: Thomas Brian C. , Yelland Alexander M. 
Published: June 2023

Abstract
We have reevaluated recent studies of the effects on Earth by cosmic rays (CRs) from nearby supernovae (SNe) at 100 and 50 pc, in the diffusive transport CR case, here including an early-time suppression at lower CR energies neglected in the previous works. Inclusion of this suppression leads to lower overall CR fluxes at early times, lower atmospheric ionization, smaller resulting ozone depletion, and lower sea-level muon radiation doses. Differences in the atmospheric impacts are most pronounced for the 100 pc case with less significant differences in the 50 pc case. We find a greater discrepancy in the modeled sea-level muon radiation dose, with significantly smaller dose values in the 50 pc case; our results indicate it is unlikely that muon radiation is a significant threat to the biosphere for SNe beyond 20 pc, for the diffusive transport case. We have also performed new modeling of the effects of SN CRs at 20 and 10 pc. Overall, our results indicate that, considering only the effects of CRs, the “lethal” SN distance should be closer to 20 pc rather than the typically quoted 8–10 pc. Recent work on extended SN X-ray emission indicates significant effects out to 50 pc and therefore the case is now strong for increasing the standard SN lethal distance to at least 20 pc. This has implications for studies of the history of life on Earth as well as considerations of habitability in the Galaxy.
Camus et la révolte devant la souffrance humaine
Authors: Spiquel Agnès 
Published: June 2023

Dans le cycle de l’absurde, le fait qu’il faille mourir est un point fondamental ; mais aussi la maladie et la vieillesse, la privation et la séparation, la lutte au coeur de contraintes aussi lourdes que le rocher de Sisyphe. Dans le cycle de la révolte, il s’agit de soigner la maladie, comme paradigme de la lutte contre tout ce qui augmente la souffrance humaine. Écrire en est un moyen, si l’oeuvre témoigne à la fois de la révolte et de l’empathie face à cette souffrance.
Souffrance, lien et solidarité
Authors: Vergely Bertrand 
Published: June 2023

Quand on est confronté à la souffrance et à la mort, la seule réponse c’est la vie. Un jour je faisais rire quelqu’un en disant : « Le mal est un problème pour vous, eh bien faites du bien et arrêtez de trouver des justifications au mal. » Faire du bien c’est la meilleure des réponses à la mort. Être philosophe ce n’est pas donner des raisons de mourir, c’est donner des raisons de vivre. Ce n’est pas donner des raisons de se suicider mais des raisons de ne pas se suicider.
L’idée de temps dans l’argument lucrétien contre la crainte de la mort (De rerum natura, III, 830‑1094)
Authors: PERALTA Alexandra 
Published: June 2023

Le thème du temps chez les épicuriens a été étudié traditionnellement d’un point de vue physique lorsque l’on s’intéresse à la nature du temps, et d’un point de vue canonique lorsque l’on se focalise sur le problème de la prénotion du temps. Dans ces deux cas, le défi est important car il n’est pas chose aisée de comprendre le statut du temps d’après une doctrine qui donne la prééminence ontologique à l’espace et à la matière. Le présent article se propose de reformuler le problème du temps chez les épicuriens, et plus exactement chez Lucrèce. Nous proposons d’étudier la notion du temps développé dans le passage III, 830-1094 du poème De rerum natura, qui vise à éliminer la crainte de la mort. Ce faisant, nous trouvons la confirmation d’une lecture non présentiste du temps qui consiste à dire que le passé, le présent et le futur existent en tant qu’accidents des corps. D’un point de vue éthique, le présent est le temps privilégié. En outre, notre analyse nous amène également à identifier une différence d’approche entre Épicure et Lucrèce en ce qui concerne l’attitude à adopter vis-à-vis du futur.

Abstract

Objective:
To determine the feasibility, reliability, and acceptability of video teleconference (VTC)-based neuropsychological assessment using Addenbrooke’s cognitive examination-III (ACE-III).

Methods:
This study was performed from January 2022 to April 2022, during the third wave of the COVID-19 pandemic in India. We administered ACE-III using video-teleconferencing and compared the scores to face-to-face (FTF) testing for the eligible participants. We also conducted a participant’s satisfaction survey of VTC-administered ACE-III compared to FTF-administered ACE-III, using a 7-point Likert scale.

Results:
We screened 37 participants and 24 (64.9%) successfully underwent ACE-III testing through VTC. We included 20 patients (mean age: 62.7 ± 10 years, mean education: 12.0 ± 4.6 years, 85% men) for final analysis, (who completed both VTC and FTF-administered ACE-III). Nine patients had major neurocognitive disorder (dementia), eight had mild neurocognitive disorder (MCI), and three had subjective cognitive decline (SCD). The two tests were administered at a median gap of 36 (18,74.5) days. The Intraclass correlation coefficients (ICC) of ACE-3 total scores (0.97) and the subdomain scores was high (>0.8). There was “very low” to “no” bias on the Bland–Altman plots, across all domains. The mean overall satisfaction score was 4.1, indicating that VTC is “as good as” FTF.

Conclusions:
Results support the feasibility and acceptability of remote administration of ACE-III via VTC. There is a good agreement between the ACE-III scores across VTC and in-person conditions.
Colostomy for Fournier's Gangrene with Rectum Exposure

Published: June 2023

Fournier's gangrene (FG) can be treated with prompt surgical debridement. Stoma revision has also been performed to prevent fecal contamination. However, recent advances in stool and wound management have reduced the need for colostomy. We report four cases of severe FG with an exposed rectum and discuss the conditions under which colostomy is indispensable. All four peoples developed FG, and an emergency debridement was performed, resulting in exposure of the rectum. Two peoples with perirectal infectious inflammation extending to the anterior rectum underwent colostomy because the inflammation had reached the retroperitoneum, but the other two, where the inflammation was confined to the dorsal-lateral rectum, were treated successfully without colostomy. We believe that colostomy can be avoided by using suitable wound management devices, except in severe cases where soft tissue infection and necrosis extend to the peritoneum and retroperitoneum and there is concern about rectal ischemia.

Cross-Cultural Awareness: EFL Learnersâ€™ Barriers to Learning English
Authors: Kustati Martin , Deswila Nurhamsi , Besral Besral , Zulfikar Teuku 
Published: June 2023

When one learns a certain language, he/she should also learn its culture. This is because languages and cultures are integrated.Â For example, to acquire meanings, language students need to understand the culture of the language they are learning. This study seeks to determine the challenges faced by English language learners in understanding Islamic beliefs and western cultures. This was a descriptive qualitative study that utilized semi-structured interviews to acquire data. Interviews were conducted with eight pupils from the Islamic boarding school Ar-Risalah in West Sumatra. The result of interviews showed that the majority of learners acknowledged that they experienced cross-cultural hurdles in English learning because of being culturally insensitive, misunderstanding of cultural contents in the language materials, and formal intervention regarding the textbook. Students are confused to differentiate cultures shared by Islamic values and Western cultures as those Islamic values are not vividly depicted in English textbooks. Therefore, students have difficulties understanding English. It is imperative that future research investigate this topic, since culture and language are inseparable, in which people learning a certain language are also required to learn its culture.

Authors: Mabunay Teresita 
Published: June 2023

The determination of the managerial efficiency of the heads of offices of DAR, particularly in the DAR municipal offices of Northern Negros Occidental, is found to be an imperative need, hence this study. For the establishment of an efficiently running agency, the level of work performance of the offices is also expected to be at par, and so is the necessity of its evaluation in this study. This descriptive research design used a researcher-made survey questionnaire with 87 personnel to answer and help determine the level of managerial efficiency of the 33 MARPOs. As to the work performance of the DAR offices, the same descriptive design was used utilizing document analysis which is the Office Performance and Commitment Review (OPCR) of the MARPOs and a checklist determined the challenges encountered by the agrarian reform offices in Part III of the questionnaire. As a whole, the level of managerial efficiency of the MARPOs is high, indicating that the MARPOs are capable and competent and have demonstrated excellence in performing their functions. Positively, the result of a high level of managerial efficiency is exhibited by the MARPOs in the discharge of their official functions and outstanding performance of the DARMOs over the years.
Implementation and Challenges of Solid Waste Management in Communities of a Component City in the Philippines
Authors: Gamao Roldan , Caelian Merlita 
Published: June 2023

Waste management is a worldwide issue other than climate change and global warming. In the ASEAN, there is an extraordinary increase in solid waste traced to urbanization, industrial development, and economic growth. While the Philippines enacted the Ecological Solid Waste Management Act, local governments passed the Environment Code. This study determined the extent of implementation of the city ordinance on solid waste management of communities in terms of the variables assessed by a sample size of 67 implementers and 384 residents identified by stratified random sampling. It also investigated the challenges encountered by the respondents in the implementation. Likewise, the differences were determined according to the geographical location of coastal, upland, and lowlands and when respondents were grouped according to designation. Using descriptive analysis, the results revealed that, as a whole, implementation of the provisions of the city ordinance is, to a great extent, with waste generation as the highest while handling and on-site storage the lowest, but several challenges were encountered. The comparative analysis revealed no significant difference in the extent of implementation when respondents were grouped according to designation in all areas except waste disposal. However, there was a significant difference when communities were grouped by geographical location, with lowland residents rating higher than the rest. Three groups of challenges emerged from the study: administrative, procedural, and policy issues.
Hearing Aid System Response Improvement
Authors: Parmar Pamraat , Sands Timothy 
Published: June 2023

This study was conducted to understand the response of hearing aids to different inputs and propose a novel technique to significantly improve performance of hearing aid implants. The motivation behind this study is to represent behavior of hearing aid system with simple input-output relation rather than complicated models. This representation offered a better understanding of the system and inspired an innovation to improve the hearing aid implants. A model of a hearing aid system called cochlear transplants is generated and used to simulate the system response. Using multiple methods, simplified input-output relations are derived. Results from these methods are compared and conclusions are drawn regarding which method is best for this application. One of the methods used resulted in 69.7 % error measure reduction compared to the benchmark method. This method was later used to produce a simplified model, which was then used as the basis for analysis of different configurations. A qualitative comparison of model was made, and significant improvement of cochlear transplants was achieved.

Control predictivo polifásico mediante dos constelaciones de vectores virtuales de tensión
Authors: Garrido Satué Manuel , Ruiz Arahal Manuel , Rodríguez Ramírez Daniel , Barrero García Federico 
Published: June 2023

En el campo de los accionamientos eléctricos de velocidad variable ha aparecido recientemente el método predictivo basado en vectores virtuales de tensión. Este método permite reducir la contribuci´on del voltaje en el subespacio x-y, en el cual no se produce par, sino pérdidas. De este modo no sólo se limitan las pérdidas sino que se reduce la complejidad de sintonía del controlador predictivo. Los vectores virtuales de tensión se obtienen mediante combinación de vectores de tensión pertenencientes a distintas coronas pequeña, media y grande además de los vectores nulos. En una aplicación típica se elige en primer lugar la(s) corona(s) a usar y después se desarrollan los vectores virtuales. El controlador predictivo usa en cada periodo de muestreo el vector virtual más adecuado. En este trabajo se propone el uso de varios conjuntos de vectores virtuales provenientes de diferentes combinaciones de coronas. Para cada punto de operación del accionamiento eléctrico se utiliza el conjunto que proporciona mejores valores de cierto criterio de bondad. El método propuesto es validado experimentalmente usando una máquina de inducción de seis fases.

The (mis)identification of high-latitude dust events using remote sensing methods in the Yukon, Canada: a sub-daily variability analysis
Authors: Huck Rosemary , Bryant Robert G. , King James 
Published: June 2023

Abstract. The observation and quantification of mineral dust fluxes from high-latitude
sources remains difficult due to a known paucity of year-round in situ
observations and known limitations of satellite remote sensing data (e.g.
cloud cover and dust detection). Here we explore the chronology of dust
emissions at a known and instrumented high-latitude dust source:
Lhù'ààn Mân (Kluane Lake) in Yukon, Canada. At this location
we use oblique time-lapse (RC) cameras as a baseline for analysis of aerosol
retrievals from in situ metrological data, AERONET, and co-incident MODIS
MAIAC to (i) investigate the daily to annual chronology of dust emissions
recorded by these instrumental and remote sensing methods (at timescales
ranging from minutes to years) and (ii) use data intercomparisons to
comment on the principal factors that control the detection of dust in each
case. Lhù'ààn Mân is a prolific mineral dust source; on
24 May 2018 the RC captured dust in motion throughout the entire day, with
the longest dust-free period lasting only 30 min. When compared with
time series of RC data, optimized AERONET data only manage an overall 26 % detection rate for events (sub-day) but 100 % detection rate for dust
event days (DEDs) when dust was within the field of view. In this
instance, RC and remote sensing data were able to suggest that the low event
detection rate was attributed to fundamental variations in dust advection
trajectory, dust plume height, and inherent restrictions in sun angle at
high latitudes. Working with a time series of optimized aerosol optical depth (AOD) data (covering
2018/2019), we were able to investigate the gross impacts of data quality (DQ) choice on
DED detection at the month or year scale. Relative to ground observations,
AERONET's DQ2.0 cloud-screening algorithm may remove as much as 97 % of
known dust events (3 % detection). Finally, when undertaking an AOD
comparison for DED and non-DED retrievals, we find that cloud screening of
MODIS/AERONET lead to a combined low sample of co-incident dust events and
weak correlations between retrievals. Our results quantify and explain the
extent of under-representation of dust in both ground and space remote
sensing methods; this is a factor that impacts on the effective calibration and
validation of global climate and dust models.

Abstract. In 2021, a group of seven Italian institutions decided to
bring together their know-how, experience, and instruments for measuring the
drop size distribution (DSD) of atmospheric precipitation, giving birth to
the Italian Group of Disdrometry (in Italian named Gruppo Italiano
Disdrometria, GID, https://www.gid-net.it/, last access: 16 May 2023). GID has made
freely available a database of 1 min records of DSD collected by the
disdrometer network along the Italian peninsula. At the time of writing, the
disdrometer network was composed of eight laser disdrometers belonging to six
different Italian institutions (including research centres, universities,
and environmental regional agencies). This work aims to document the
technical aspects of the Italian DSD database consisting of 1 min
sampling data from 2012 to 2021 in a uniform standard format defined within
GID. Although not all the disdrometers have the same data record length, the
DSD data collection effort is the first of its kind in Italy, and from here
onwards, it opens up new opportunities in the surface characterization of
microphysical properties of precipitation in the perspective of climate
records and beyond. The Version 01 GID database can be downloaded at
https://doi.org/10.5281/zenodo.6875801 (Adirosi et al., 2022), while Version
02 can be downloaded at https://doi.org/10.5281/zenodo.7708563 (Adirosi et
al., 2023). The difference among the two versions is the diameter–fall
velocity relation used for the DSD computation.
A comparison of 3-D spherical shell thermal convection results at low to moderate Rayleigh number using ASPECT (version 2.2.0) and CitcomS (version 3.3.1)

Published: June 2023

Abstract. Due to the increasing availability of high-performance computing over the past few decades, numerical models have become an important tool for research in geodynamics.
Several generations of mantle convection software have been developed, but due to their differing methods and increasing complexity it is important to evaluate the accuracy of each new model generation to ensure published geodynamic research is reliable and reproducible.
Here we explore the accuracy of the open-source, finite-element codes ASPECT and CitcomS as a function of mesh spacing using low to moderate-Rayleigh-number models in steady-state thermal convection.
ASPECT (Advanced Solver for Problems in Earth's ConvecTion) is a new-generation mantle convection code that enables modeling global mantle convection with realistic parameters and complicated physical processes using adaptive mesh refinement (Kronbichler et al., 2012; Heister et al., 2017).
We compare the ASPECT results with calculations from the finite-element code CitcomS (Zhong et al., 2000; Tan et al., 2006; Zhong et al., 2008), which has a long history of use in the geodynamics community.
We find that the globally averaged quantities, i.e., root-mean-square (rms) velocity, mean temperature, and Nusselt number at the top and bottom of the shell, agree to within 1 % (and often much better) for calculations with sufficient mesh resolution.
We also show that there is excellent agreement of the time evolution of both the rms velocity and the Nusselt numbers between the two codes for otherwise identical parameters.
Based on our results, we are optimistic that similar agreement would be achieved for calculations performed at the convective vigor expected for Earth, Venus, and Mars.
