Evaluation of the optical and electrical properties of (C8BTBT)(F4TCNQ) charge-transfer complexes according to film formation temperatures during solution coating
Authors: Uchiyama Naomi , Matsuura Yuji 
Published: November 2024

Abstract
This study focused on (C8BTBT)(F4TCNQ) charge-transfer complexes, where C8BTBT is 2,7-dioctyl[1]benzothieno[3,2-b][1]benzothiophene and F4TCNQ represents fluorinated derivatives of 7,7,8,8,-tetracyanoquinodimethane. These complexes exhibit excellent thermal and atmospheric stability and near-infrared absorption, serving as transparent thin films for photoelectric conversion. Here, we sought to improve the photoelectric conversion efficiency (and thus the quantum efficiency, QE) of (C8BTBT)(F4TCNQ) thin films by altering the film formation temperatures during solution coating; we evaluated the optical and electrical properties of the films. We found that increased film coverage of a substrate surface (leading to continuous film formation) enhanced optical absorption and improved the photocurrent extraction efficiency when these films were incorporated into devices. C8BTBT and its components, when present alone, negatively affected both the device fabrication yield and photocurrent extraction. It is thus important to maximize (C8BTBT)(F4TCNQ) formation when seeking to improve the QE.
Impact of post-deposition annealing on SiO2/SiC interfaces formed by plasma nitridation of the SiC surface and SiO2 deposition
Authors: Fujimoto Hiroki , Kobayashi Takuma , Watanabe Heiji 
Published: November 2024

Abstract
We examined the impact of post-deposition annealing (PDA) on SiO2/SiC structures formed by plasma nitridation of the SiC surface followed by sputter deposition of SiO2. The interface state density near the conduction band edge of SiC was reduced from about 2 × 1012 to 1 × 1011 eV−1 cm−2 as the CO2-PDA temperature increased from 1050 °C to 1250 °C. In addition, the sample treated by CO2-PDA exhibited substantially higher immunity against positive gate bias stress than the standard NO nitridation. Our findings indicate that defect passivation by CO2-PDA plays a crucial role in improving the performance and reliability of SiC MOS devices formed by sputter-SiO2 deposition.

A embolia pulmonar ocorre quando um êmbolo bloqueia as artérias pulmonares, muitas vezes como resultado de trombose venosa profunda. A condição é grave, com elevada morbimortalidade e sinais clínicos inespecíficos, o que dificulta o diagnóstico. Fatores de risco incluem trombose venosa profunda prévia, imobilização prolongada e obesidade, destacando a necessidade de diagnóstico precoce para reduzir as complicações. Este artigo objetiva analisar o perfil epidemiológico da embolia pulmonar no Brasil de 2013 a 2023, usando dados do Sistema de Informações Hospitalares do SUS. O estudo, de caráter observacional, retrospectivo e descritivo, mostrou uma redução na taxa de mortalidade por embolia pulmonar, mas um aumento significativo nas internações. Foram registradas 100.881 internações, predominantemente na Região Sudeste, mas com aumento progressivo no Nordeste. A maior parte das hospitalizações correu em idosos (51%), com maior incidência em mulheres (61,1%) e brancos (57,8%). Foram registrados 18.658 óbitos, com um aumento de 46% entre 2013 e 2023, sendo a maioria deles ocorrida em indivíduos com mais de 60 anos (69,4%), mulheres (59%), brancos (43,7%) e pardos (29%). Ocorreram mais óbitos no Sudeste (54,8%), enquanto o Nordeste teve a maior taxa de mortalidade (24,02). Comorbidades, como doenças cardiovasculares, agravam o quadro clínico e aumentam as chances de internação. Existem disparidades regionais no Brasil, com maiores taxas de mortalidade em regiões com infraestrutura sanitária precária. O envelhecimento aumenta o risco de embolia pulmonar, elevando as internações entre idosos. Mulheres são mais suscetíveis a doenças tromboembólicas, mas homens apresentam maior mortalidade. Diferenças raciais na incidência e mortalidade por embolia pulmonar mostram maior letalidade entre pretos. Conclui-se que mais pesquisas são necessárias para entender o cenário da embolia pulmonar no Brasil, além da necessidade de políticas públicas que considerem disparidades regionais, envelhecimento e diferenças de gênero e raça.

Where does the processing of size meet the processing of space?
Authors: Wühr Peter , Heuer Herbert 
Published: November 2024

AbstractPrevious studies revealed an S-R compatibility effect between physical stimulus size and response location, with faster left (right) responses to small (large) stimuli, respectively, as compared to the reverse assignments. Here, we investigated the locus of interactions between the processing of size and spatial locations. In Experiment 1, we explored whether stimulus size and stimulus location interact at a perceptual level of processing when responses lack spatiality. The stimuli varied on three feature dimensions (color, size, location), and participants responded vocally to each feature in a separate task. Most importantly, we failed to observe a size-location congruency effect in the color-naming task where S-R compatibility effects were excluded. In Experiment 2, responses to color were spatial, that is, key-presses with the left and right hand. With these responses there was a congruency effect. In addition, we tested the interaction of the size-location compatibility effect with the Simon effect, which is known to originate at the stage of response selection. We observed an interaction between the two effects only with a subsample of participants with slower reaction times (RTs) and a larger size-location compatibility effect in a control condition. Together, the results suggest that the size-location compatibility effect arises at the response selection stage. An extended leaky, competing accumulator model with independent staggered impacts of stimulus size and stimulus location on response selection fits the data of Experiment 2 and specifies how the size-location compatibility effect and the Simon effect can arise during response selection.

According to Law no. 43 of 2007 Libraries are institutions that manage collections of written works, printed works and/or artistic works professionally with a good system to meet the educational, research, preservation, information and recreational needs of users. The National Library of the Republic of Indonesia is the national institution that implements this law. The aim of this research is to analyze user satisfaction at the National Library of the Republic of Indonesia at the Central Unit of Library Services and Manuscript Collections and analyze service quality as a mediator variable. The variables used as factors influencing user satisfaction in this research are facilities and information technology. The research was conducted by surveying 100 visiting users using convenience sampling techniques. Data analysis was carried out using path analysis. The results of the research are that there is an influence of facilities and information technology on service quality and service quality has an influence on user satisfaction. Service quality is a mediating variable, meaning that user satisfaction is influenced by facilities both directly and indirectly through service quality and user satisfaction is influenced by information technology both directly and indirectly through service quality.

Authors: Lima Mileide Emilly Silvano de , Silva Tallyson Menezes Bento da 
Published: November 2024

Introdução: Infecções hospitalares disseminadas por Klebsiela Pneumoniae, uma bactéria multirresistente produtora de carbapenemase, tem um importante impacto clínico e epidemiológico nas infecções relacionadas à assistência à saúde, pois a produção desta enzima a torna um patógeno difícil de controlar. A maioria dessas infecções está associada a pacientes internados por períodos prolongados, com necessidade do uso de dispositivos e antibióticos, para pacientes que passaram por procedimentos como por exemplo os transplantes de órgãos o risco se torna ainda maior. Além dos procedimentos padrões já amplamente conhecidos para evitar a propagação desse tipo de infecção, é importante ressaltar que como profissional do medicamento o farmacêutico possui um papel fundamental no controle dessas infecções hospitalares auxiliando com as questões relacionadas a farmacocinética e farmacodinâmica diminuindo significativamente o risco do desenvolvimento de resistências bacterianas ou complementando tratamentos específicos para os patógenos que já desenvolveram essas enzimas. Por ser uma questão de saúde pública e colocar em risco a vida dos pacientes a infecção hospitalar por bactérias multirresistentes é um assunto de extrema importância e que deve ser tratado com seriedade por uma equipe multidisciplinar especializada. Objetivo: compreender a importância da análise farmacêutica na detecção da prevalência da Klebsiela Pneumoniae em pacientes transplantados. Método: A coleta dos dados para a composição dessa pesquisa bibliográfica ocorrerá através da exploração da base de dados da Biblioteca Virtual em Saúde (BVS), Biblioteca Cientifica Eletrônica Virtual (SCIELO) e Literatura Latino–Americana e do Caribe em Ciências da Saúde (LILACS). Resultados: Os transplantados são um grupo de pacientes com risco para Infecções Relacionadas à Assistência à Saúde (IRAS), devido à gravidade clínica, procedimentos invasivos, ventilação mecânica, imunossupressores, antimicrobianos e exposições múltiplas ao ambiente hospitalar. Estes fatores são preditores para colonização e infecção por bactérias multirresistentes, como a Klebisiela Pneumoniae. Conclusões: Frente ao desenvolvimento desse estudo foi possível compreender a importância da análise farmacêutica na detecção da prevalência da Klebsiela Pneumoniae em pacientes transplantados, ficando evidenciado que essa infecção é extremamente nociva a esses pacientes, tendo em vista a sua resistência frente a antibióticos, dessa forma cabe ao profissional farmacêutico através de sua análise, detectar a presença do patógeno precocemente, a fim de minimizar os danos ao paciente em momento de fragilidade imunológica.

Abstract
The detection of stellar variability often relies on the measurement of selected activity indicators, such as coronal emission lines and nonthermal emissions. On the flip side, the effective stellar temperature is normally seen as one of the key fundamental parameters (with mass and radius) to understanding the basic physical nature of a star and its relation with its environment (e.g., planetary instellation). We present a novel approach for measuring disk-averaged temperature variations to sub-Kelvin accuracy inspired by algorithms developed for precision radial velocity (pRV). This framework uses the entire content of the spectrum, not just preidentified lines, and can be applied to existing data obtained with high-resolution spectrographs. We demonstrate the framework by recovering the known rotation periods and temperature modulation of Barnard star and AU Mic in data sets obtained in the infrared with SPIRou at CHFT and at optical wavelengths on ϵ Eridani with HARPS at ESO 3.6 m telescope. We use observations of the transiting hot Jupiter HD189733b, obtained with SPIRou, to show that this method can unveil the minute temperature variation signature expected during the transit event, an effect analogous to the Rossiter–McLaughlin effect but in temperature space. This method is a powerful new tool for characterizing stellar activity, and in particular temperature and magnetic features at the surfaces of cool stars, affecting both pRV and transit spectroscopic observations. We demonstrate this method in the context of high-resolution spectroscopy but it could be used at lower resolution.

Published: November 2024

Abstract
Measurements of oxygen abundance throughout galaxies provide insight to the formation histories and ongoing processes. Here we present a study of the gas-phase oxygen abundance in the H ii regions and diffuse gas of the nearby starburst dwarf galaxy, IC 10. Using the Keck Cosmic Web Imager at W. M. Keck Observatory, we map the central region of IC 10 from 3500 to 5500 Å. The auroral [O III] 4363 Å line is detected with a high signal-to-noise ratio in 12 of 46 H II regions observed, allowing for direct measurement of the oxygen abundance, yielding a median and standard deviation of

. We investigate trends between these directly measured oxygen abundances and other H II region properties, finding weak negative correlations with the radius, velocity dispersion, and luminosity. We also find weak negative correlations between the oxygen abundance and the derived quantities of turbulent pressure and ionized gas mass, and a moderate correlation with the derived dynamical mass. Strong line, R
23 abundance estimates are used in the remainder of the H II regions and on a resolved spaxel-by-spaxel basis. There is a large offset between the abundances measured with R
23 and the auroral line method. We find that the R
23 method is unable to capture the large range of abundances observed via the auroral line measurements. The extent of this variation in the measured abundances further indicates a poorly mixed interstellar medium in IC 10, which is not typical of dwarf galaxies and may be partly due to the ongoing starburst, accretion of pristine gas, or a late stage merger.
A Broad Set of Solar and Cosmochemical Data Indicates High C-N-O Abundances for the Solar System

Abstract
We examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper Belt objects (KBOs) and CI chondrites. By utilizing Rosetta measurements of refractory organics in comet 67P/Churyumov–Gerasimenko, we show that they would make up a large fraction of the protosolar C inventory in the KBO-forming region based on the current widely adopted solar abundances. However, this would free up too much O to form water ice, producing solid material that is not sufficiently rock-rich to explain the uncompressed density of the Pluto–Charon system and other large KBOs; the former has been argued as the most representative value we have for the bulk composition of large KBOs. This inconsistency further highlights the solar abundances problem—an ongoing challenge in reconciling spectroscopically determined heavy-element abundances with helioseismology constraints. By employing a new data set from solar CNO neutrinos and solar wind measurements of C, N, and O, we show that the uncompressed density of the Pluto–Charon system can be reproduced over a wide range of scenarios. We show that a lack of sulfates in Ryugu and Bennu samples implies a lower amount of water ice initially accreted into CI chondrite parent bodies than previously thought. These data are found to be consistent with the solar C/O ratio implied by the new data set. Our predictions can be tested by future neutrino, helioseismology, and cosmochemical measurements.

Abstract
We present our analysis of MAXI J1813−095 during its hard state “stalled” outburst in 2018. This self-consistent analysis has been carried out using the Neutron Star Interior Composition Explorer, Swift, Chandra, and NuSTAR throughout seven observations of MAXI J1813−095. We find a relativistic iron line at ∼6.5 keV from the inner region of the accretion disk. Our results are consistent with a slightly truncated disk or nontruncated disk for an inner radius of ∼2R
g and minimum spin of >0.7 with the best value of ∼0.9, assuming R

Edd. We analyzed MAXI J1813−095 over its outburst, employing a spectral model that self-consistently couples the seed disk photons to the Comptonization and reflection components, also inclusive of reflection Comptonization. The unique aspect of this work is a reflection fraction of order unity, which is significantly higher than previous studies of this source and is a consequence of applying the self-consistent disk-Comptonization-reflection spectral model. Other key parameters, such as inclination and inner radius, are found to be consistent with other works.
Magnetically Aligned Grains as a Ubiquitous Source of Spin-polarized Electrons and Chiral-symmetry-breaking Agents
Authors: Hoang Thiem 
Published: November 2024

Abstract
The unique biosignature of life on Earth is the homochirality of organic compounds, such as amino acids, proteins, and sugars. High-energy spin-polarized (spinup or spindown) electrons (SPEs) from the β decay of radioactive nuclei have been proposed as a source of symmetry breaking, leading to homochirality; however, their exact role is much debated. Here, we propose magnetically aligned dust grains as a new source of SPEs, due to the photoemission of electrons having aligned spins by the Barnett effect. For the interstellar UV radiation field of strength G
UV, we find that the SPE emission rate is

electrons per second per H, the fraction of spin-polarized to total photoelectrons is ∼10%, and the SPE yield (photoelectron number per UV photon) can reach ∼1%, using the modern theory of grain alignment. SPEs emitted from aligned grains could play an important role in chiral-induced spin-selectivity-driven reduction chemistry in the icy grain mantles, producing an enantiomer excess of chiral molecules formed on the grain mantle. Finally, we suggest magnetically aligned grains could directly impact the enantio-selectivity through the chiral-induced spin-selective adsorption effect and exchange interaction. We estimate the disalignment of electron spins and depolarization by elastic scattering using the Mott theory and find that these effects are negligible for low-energy SPEs, so that the spins of SPEs remain well aligned during their journey through dust grains and the gas. Our proposed mechanism might explain the chiral asymmetry of prebiotic molecules detected in numerous comets, asteroids, and meteorites.
Effect of Time-varying X-Ray Emission from Stellar Flares on the Ionization of Protoplanetary Disks
Authors: Washinoue Haruka , Takasao Shinsuke , Furuya Kenji 
Published: November 2024

Abstract
X-rays have significant impacts on cold, weakly ionized protoplanetary disks by increasing the ionization rate and driving chemical reactions. Stellar flares are explosions that emit intense X-rays and are the unique source of hard X-rays with an energy of ≳10 keV in the protoplanetary disk systems. Hard X-rays should be carefully taken into account in models as they can reach the disk midplane as a result of scattering in the disk atmospheres. However, previous models are insufficient to predict the hard X-ray spectra because of simplifications in flare models. We develop a model of X-ray spectra of stellar flares based on observations and flare theories. The flare temperature and nonthermal electron emissions are modeled as functions of flare energy, which allows us to better predict the hard X-ray photon flux than before. Using our X-ray model, we conduct radiative transfer calculations to investigate the impact of flare hard X-rays on disk ionization, with a particular focus on the protoplanetary disk around a T Tauri star. We demonstrate that for a flare with an energy of 1035 erg, X-ray photons with ≳5 keV increase the ionization rates more than galactic cosmic rays down to z ≈ 0.1R. The contribution of flare X-rays to the ionization at the midplane depends on the disk parameters such as disk mass and dust settling. We also find that the 10 yr averaged X-rays from multiple flares could certainly contribute to the ionization. These results emphasize the importance of stellar flares on the disk evolution.
