Abstract
The large-scale environment of the cosmic web is believed to impact galaxy evolution, but there is still no consensus regarding the mechanisms. We use a semi-analytic model (SAM) galaxy catalog to study the star formation and dust content of local galaxies in different cosmic environments of the cosmic web—namely voids, filaments, walls, and nodes. We find a strong impact of the environment only for galaxies with M
stars ≲ 1010.8
M
⊙: the less dense the environment, the larger the star formation rate and dust content at fixed stellar mass. This is attributed to the fact that galaxies in less dense environments typically feature younger stellar populations, a slower evolution of their stellar mass, and delayed star formation compared to galaxies in denser environments. As for galaxies with M
stars ≳ 1010.8
M
⊙, the differences among environments are milder, due to the disk-instability-driven supermassive black hole (SMBH) growth implemented in the SAM, which makes SMBH growth, and thus galaxy quenching, environment-insensitive. We qualitatively test our predictions against observations by identifying environments in Sloan Digital Sky Survey Data Release 16 using dust masses derived from the GAMA survey. The agreement is encouraging, particularly at

Published: May 2024

Abstract
In the solar wind turbulence, proton temperature fluctuations are highly intermittent, especially at small scales in the inertial range. This phenomenon may contain information about solar wind intermittent heating. However, the physical nature of the temperature intermittency is not yet clear. Based on the measurements from Solar Orbiter between 2020 September and 2022 September, we identify 185 temperature intermittent structures at the scale of 24 s with well-defined minimum variance direction in the fast solar wind and study the nature and kinetic effects of them. According to the variations of proton temperature, the intermittent structures are classified into four types, including temperature bump, step, dip, and chain. When considering the magnetic field configuration together with other plasma properties, we find that, among the bump cases, 46 of them are linear magnetic holes (LMHs) that are mainly related to mirror-mode (MM) instability, and 43 of them are current sheets (CSs) with local temperature enhancement. The step cases are found to be associated with shock-like structures (13 cases) and tangential discontinuities (eight cases) that separate two different parcels of plasma. For the dip cases, 21 of them could be associated with the MM instability, and the rest of the 16 ones may prefer soliton scenario. The 38 chain cases are identified as compressive vortex-like structures and a mixture of LMHs and CSs. These results will help to further understand the intermittent dissipation process in the solar wind turbulence.

Abstract
Potentially habitable exoplanets are targets of great interest for the James Webb Space Telescope and upcoming mission concepts such as the Habitable Worlds Observatory. Clouds strongly affect climate and habitability, but predicting their properties is difficult. In Global Climate Models (GCMs), especially those aiming at simulating Earth, cloud microphysics is often crudely approximated by assuming that all cloud particles have a single, constant size or a prescribed size distribution and that all clouds in a grid cell are identical. For exoplanets that range over a large phase space of planetary properties, this method could result in large errors. In this work, our goal is to determine how cloud microphysics on terrestrial exoplanets, whose condensable is mainly water vapor, depend on aerosol properties and planetary parameters such as surface pressure, surface gravity, and incident stellar radiation. We use the Community Aerosol and Radiation Model for Atmospheres as a 1D microphysical model to simulate the formation and evolution of clouds including the processes of nucleation, condensation, evaporation, coagulation, and vertical transfer. In these 1D idealized experiments, we find that the parameters that determine the macrophysical thermal structure of the atmospheres, including surface pressure and stellar flux, impact cloud radiative effect (CRE) most significantly. Parameters such as gravity and number density of aerosols working as cloud condensation nuclei affect the microphysical processes of cloud formation, including activation and vertical transfer. They also have a significant, though weaker effect on CRE. This work motivates the development of more accurate GCM cloud schemes and should aid in the interpretation of future observations.
Exogenous Carbon is Unlikely to be the Source of Methane Microseepage Emissions on Mars
Authors: Moores John E. , Sapers Haley M. , Schuerger Andrew C. 
Published: May 2024

Abstract
A complete understanding of methane in the atmosphere of Mars requires information on putative sources. Organic carbon derived from meteoritic sources, such as interplanetary dust particles (IDPs), over geologic time is the best-defined source of organic carbon on the surface of Mars. Here we examine two different mechanisms for degrading this material to produce methane (1) Ultraviolet photolysis and (2) thermal decomposition. Neither of these mechanisms can produce sufficient methane under realistic assumptions to explain observed methane at Gale Crater, suggesting that IDPs are not the primary source material producing methane on Mars.
Not in the countryside please! Investigating UK residents’ perceptions of an introduced species, the ring-necked parakeet (Psittacula krameri)

Published: May 2024

Wildlife management can generate social conflict when stakeholder perceptions of the target species are not considered. Introduced Ring-necked Parakeets (RNP) are established in the UK and have been added to the ‘general licence’ of birds that can be killed to prevent serious economic damage. We aimed to better understand perceptions of RNPs on a nationwide scale to inform mitigation actions for potential future conflict over RNP management. We surveyed 3,947 UK residents to understand awareness of, knowledge of and attitudes towards the RNP across the UK.
We found that most respondents (90.2%) were aware of the RNP. Almost half of respondents (45.9%) held negative opinions, particularly against the RNP in rural areas (64.7%), suggesting landscape contexts influence attitudes. Respondent preference for the RNP was low in local neighbourhoods (7.80%) although the species was considered aesthetically pleasing by most (83.0%). Many respondents knew the species’ name (54.9%), but underestimated current population numbers in the UK (82.6%) and few knew its full native range (10.0%). We identified respondents’ ecological interest, age, education, preference for, awareness of and knowledge of the RNP as significant factors associated with perceptions.
Our findings suggest that the RNP presents a complex socio-environmental challenge, with respondent awareness, knowledge and attitudes each forming an important component of perceptions towards this species. We recommend that wildlife managers utilise our findings and cohesive approach to enhance future RNP perception research in the UK and abroad and towards the success of any proposed management initiatives under the UK general licence.

Il s’agit d’une rencontre, dans la nuit des mots et des idées, pour parler de la nuit, avec un langage qui ne cherche pas à définir, mais qui se laisse porter par le courant de ce qui se dit dans une écoute et une interpellation mutuelles. On découvre au fur et à mesure que la nuit peut durer ; que dans la durée elle agit comme révélatrice ; que nous avons à lui survivre, en posant simplement un premier pas ; que d’autres fois nous gagnerions plutôt à l’écouter et à recevoir d’elle notre mission, à la laisser nous dépouiller du faux et de ce qui nous encombre, d’une protection qui ne protège plus que la mort en nous, pour nous conduire vers l’aimé.

Oral isotretinoin versus acitretin in the treatment of plantar warts in adults
Authors: Nofal Ahmad A.E. , Najah Samar M. , ElShafy Ahmed S.A. 
Published: May 2024

Background
Plantar warts are benign epithelial tumors that are forced inward due to pressure on the toes or sole of the foot and may become very painful if not treated. Many treatment options are available including topical treatments, lasers, and immunotherapy. However, data about systemic therapies are lacking.

Objective
To compare the efficacy and safety of acitretin versus oral isotretinoin in the treatment of multiple plantar warts.

Patients and methods
This randomized comparative double-blinded study included 80 adult patients with multiple plantar warts. The cases were divided into two groups: acitretin group (40 cases with a dose of 0.5 mg/kg/day) and isotretinoin group (40 cases with a dose of 0.5 mg/kg/day). The reduction in wart size and photographic comparisons at the beginning and every 2 weeks for 3 months were used to assess the treatment efficacy in the two groups. After therapy ended, a follow-up was conducted every month for 6 months to observe any recurrence.

Results
Complete response was observed in 30%, partial response in 55%, and no response in 15% of patients of acitretin group while complete response was achieved in 15%, partial response in 45%, and no response in 40% of patients of isotretinoin group with statistically significant difference in favor of acitretin (P=0.03). Compared with acitretin, oral isotretinoin was associated with a shorter duration to a complete response (83.3% of cases achieved complete response in <2 months compared with only 16.7% in acitretin group) (P=0.006).

Conclusion
Acitretin is superior to oral isotretinoin as a therapeutic option for plantar warts, but both are effective and safe. Since they are resistant to other traditional therapy techniques, they can be seen as valuable therapeutic choices for multiple plantar warts.

ABSTRACT

Objectives:
This study was conducted to evaluate the efficacy of turmeric, ashwagandha, and aloe vera in the management of oral lichen planus (OLP) lesion.

Materials and Methods:
Thirty patients with histologically confirmed symptomatic OLP with gingival presentation were included in this comparative investigation. Three groups of participants were created: Group I consisted of turmeric; group II included ashwagandha; and group III included aloe vera. For 3 weeks in a row, they were told to apply topical treatments twice a day. The patients were recalled for 4 to evaluate the cessation of symptoms.

Result:
The participants in all the groups showed a considerable improvement in the burning lesion size and pain after 4 months of follow-up.

Conclusion:
For the treatment of OLP, turmeric, ashwagandha, and aloe vera can be useful as substitute topical medications, particularly for those who are not responsive to topical corticosteroids.
Efficient pitch‐estimation network for edge devices
Authors: Jeong Chi Yoon , Song Youngmi , Shin Sungyong , Kim Mooseop 
Published: May 2024

AbstractPitch estimation is the task of finding the most conspicuous frequency in a complex audio signal. Many methods that use deep neural networks have significantly increased the accuracy of pitch estimation; however, their real‐time performance results were achieved on high‐performance devices. Because pitch estimation is widely used in real‐time applications on low‐power devices, we propose an efficient method for estimating pitch on edge devices. The network architecture of the proposed method uses a depth‐scaling strategy and fully leverages convolutional networks. We further introduce a channel attention mechanism to increase accuracy without increasing computational overhead. We compared the proposed model with state‐of‐the‐art (SOTA) and conventional methods using two public datasets. The experimental results show that the proposed method has a better classification accuracy than FCNF0++, which is the best performing SOTA model. Furthermore, it reduces the processing time obtained by FCNF0++ on a personal computer and two edge devices by 48% on average. These experimental results confirm that the proposed method efficiently classifies pitch on edge devices.

ABSTRACT.
Soil-transmitted helminthiasis remains a notable health problem in developing countries. In 1990 in Shanghai, a city in eastern China, 47% of the population was affected. Due to a series of comprehensive approaches, the prevalence decreased to 0.5% in 2009. We collected 10-year surveillance data to assess the epidemic situation of soil-transmitted helminth (STH) infections in Shanghai. Stool samples and questionnaires from participants were collected. The Kato-Katz technique was used to detect infections with Ascaris lumbricoides, hookworm (Ancylostoma duodenale and Necator americanus), and Trichuris trichiura. From 2014 to 2023, a total of 77,685 participants were screened for parasitic infections, and the overall prevalence of STH infections decreased from 0.1% to 0% in Shanghai. Of 77,685 participants, 25 (0.03%) were positive for intestinal helminths, with the most common parasite being A. lumbricoides (72.0%). Generally, elderly participants from rural areas with lower education levels were more likely to be infected with STHs. A total of 2,914 questionnaires were collected, and most respondents (72.6%) had good knowledge about the transmission routes of STHs. However, 12.3% of participants did not know the damage to health caused by STHs, and 19.3% had no idea of how to prevent infection. These data demonstrate the current state of STH infections in Shanghai. The results suggest that various comprehensive measures should be encouraged, continuously implemented, and strengthened accordingly so that STH elimination can be integrated into the Healthy China initiative by 2030.

Six metal chlorides of vanadium, zirconium, niobium, tantalum, gallium, and tellurium (i.e., VCl3, ZrOCl2×8H2O, NbCl5, TaCl5, GaCl3, and TeCl4) were reacted with urea (referred to as U) in aqueous media at ~ 50 oC. The resulting metal-urea complexes were characterized using CHN elemental analyses, infrared (IR) spectroscopy, and thermogravimetry. After the synthesized metal-urea complexes were characterized, their ability to form stable metal oxides was examined. The vanadium(IV) oxide; VO2, zirconium(IV) oxide; ZrO2, niobium(IV) oxide, NbO2, tantalum(IV) oxide; TaO2, gallium(III) oxide; Ga2O3, and tellurium(IV) oxide; TeO2, were generated by the thermal decomposition route of the synthesized metal-urea complexes at low temperature 600 °C in static air atmosphere. The transmission electron microscopy (TEM) revealed that the oxides contain uniform spherical nanoparticles.

The coordination polymer, [Co(L)(hip)]n (1), (L = 11-fluoro-pyridine[3,2-a:2',3'-c]phenazine and H2hip = 5-hydroxyisophthalic acid), has been successfully synthesized under hydrothermal condition. Complex 1 crystallizes in tetragonal, space group P43212 and the asymmetric unit consists of one Co(II) ion, one hip2- anion and one ligand L. The binuclear [Co2(L)2(hip)4]4- second building unit is formed by the coordination of four different hip2- anions and two Co(L) moieties. The adjacent Co(Ⅱ) centers are connected by the bridging hip2- anions to form a one-dimensional helical chain. Finally, a three-dimensional structure is formed by the self-assembly of the coordination bond between the Co centers and the hip2- anions. The powder X-ray diffraction, thermal analysis, IR analysis, UV-Vis absorption spectrum, photoluminescent properties and theoretical calculation for complex 1 are straight displayed.

Diagnóstico de la Cultura Empresarial. Comparación con otros estudios
Authors: López Torres LLemel , Cruz Cordero Teresa 
Published: May 2024

Este diagnóstico enriquece y corrobora otros estudios donde se hacen generalizaciones de las manifestaciones de la cultura organizacional empresarial, al mismo tiempo que se podemos encontrar resultados no tan sorpresivos con relación al cambio en la cultura empresarial.

En los indicadores de los sistemas culturales que se ponen de manifiesto con mayor frecuencia en los empresarios se destacan los siguientes: Actitud ante el trabajo, ritos y ceremonias, la preocupación de los miembros de la organización se centra en la empresa, creencias y valores. Es importante mantener e incentivar estos resultados en función de potenciar los procesos y garantizar el cumplimiento de los objetivos.

Resulta interesante destacar que la innovación, los riesgos y el enfoque estratégico no se consideran de forma significativa, razón por la cual habría que tomar acciones para mejorar esta orientación. Es importante estudiar la cultura organizacional, ya que la identificación de sus paradigmas y de los indicadores de los sistemas de gestión, cultura y humanos, marcan los comportamientos de los individuos en la organización lo que contribuye al desarrollo de la sostenibilidad en la empresa.

Published: May 2024

Hay muchas razones para pensar que el ambiente organizativo, legal, económico, comercial y cultural existente en muchas de nuestras naciones, no favorece todo lo posible el surgimiento y desarrollo de pequeñas empresas; que puedan evolucionar desde la micro y pequeña organización, hasta variantes mayores; y así crear la necesaria riqueza y consecuentemente los empleos requeridos, para que la prosperidad beneficie a los sectores no siempre favorecidos de nuestras sociedades. Debido a ello, nuestras economías devienen “economías de timbiriches”, con miles de empresas que nunca crecen, y que malamente permiten alimentarse a sus dueños.Se presentan aquí algunas prácticas empresariales dignas de ser conocidas, aquellas que las llevaron de ser microempresas al borde de la desaparición, a lo que son hoy. Se tratará de destacar éxitos, pero también errores. De la misma manera, se darán pautas para que nuestras empresas puedan surgir de una manera positiva, alternando resultados buenos y malos para tener como un punto de partida en nuestras empresas.
