Abstract
Studies of fundamental parameters of very low-mass objects are indispensable to provide tests of stellar evolution models that are used to derive theoretical masses of brown dwarfs and planets. However, only objects with dynamically determined masses and precise photometry can effectively evaluate the predictions of stellar models. AB Dor C (0.090 M
⊙) has become a prime benchmark for calibration of theoretical evolutionary models of low-mass young stars. One of the ambiguities remaining in AB Dor C is the possible binary nature of this star. We observed AB Dor C with the VLTI/AMBER instrument in low-resolution mode at the J, H, and K bands. The interferometric observables at the K band are compatible with a binary brown dwarf system with tentative components AB Dor Ca/Cb with a K-band flux ratio of 5% ± 1% and a separation of 38 ± 1 mas. This implies theoretical masses of 0.072 ± 0.013 M
⊙ and 0.013 ± 0.001 M
⊙ for each component, near the hydrogen-burning limit for AB Dor Ca, and near the deuterium-burning limit, straddling the boundary between brown dwarfs and giant planets, for AB Dor Cb. The possible binarity of AB Dor C alleviates the disagreement between observed magnitudes and theoretical mass–luminosity relationships.

Abstract
We report the detection of a large-amplitude MIR outburst in the white dwarf (WD) 0145+234 in the NEOWISE Survey data. The source had a stable MIR flux before 2018, and was brightened by about 1.0 magnitude in the W1 and W2 bands within half a year and has been continuously brightening since then. No significant variations are found in the optical photometry data during the same period. This suggests that this MIR outburst is caused by recent replenishing or redistribution of dust, rather than intrinsic variations of the WD. Spectral energy distribution modeling of 0145+234 suggests that there was already a dust disk around the WD in the quiescent state, and both of the temperature and surface area of the disk evolved rapidly since the outburst. The dust temperature was ≃1770 K in the initial rising phase, close to the sublimation temperature of silicate grains, and gradually cooled down to around 1150 K, while the surface area increased by a factor of about six during the same period. The inferred closest distance of dust to the WD is within the tidal disruption radius of a gravitationally bounded asteroid. We estimated the dust mass to be between 3 × 1015 and 3 × 1017
ρ/(1 g cm−3) kg for silicate grains of a power-law size distribution with a high cutoff size from 0.1 to 1000 μm. We interpret this as a possible tidal breakup of an exoasteroid by the WD. Further follow-up observations of this rare event may provide insights on the origin of dust disk and metal pollution in some WDs.
Comparative evaluation of conventional cytology and a low-cost liquid-based cytology technique, EziPREP™, for cervicovaginal smear reporting: A split sample study

Published: November 2019

Background:
Liquid-based cytology (LBC) for cervical cancer screening offers several advantages over conventional cytology. However, the extremely high cost of the current approved devices precludes widespread application of LBC technique in resource-constrained countries. This study aimed to evaluate the performance of an indigenous low-cost LBC technique, EziPREP™ (EP), against conventional preparations (CPs) for cervical cancer screening.

Materials and Methods:
A cross-sectional split-sample study with consecutive cervical sampling was conducted on 515 women attending the clinic at our institute. CP smears were prepared as per the standard technique using spatula and endocervical brush followed by detaching the head of brush into the fixative vial of EP. The EP samples were processed as per the manufacturer's protocol. Both CP and EP smears were stained using standard Papanicolaou stain protocol. Both sets of smears were evaluated for staining quality, morphologic details, and cytologic diagnoses. Cytologic diagnoses were correlated with cervical biopsy findings, wherever available. Performance characteristics of the two techniques were calculated.

Results:
The unsatisfactory rate for CP was 1.0%, while on EP, 1.3% smears had inadequate cellular material. The staining quality and morphological details were comparable in both sets of smears. The detection of infections and epithelial cell abnormality was more, though not statistically significant in EP smears. There was a 98% concordance in cytologic diagnosis between CP and EP smears. Cytohistologic concordance was observed in 96% of cases for both CP and EP smears. Although the time taken for processing and staining of smears was higher for EP (2.5 min for EP per smear and 1.6 min for CP per smear), the screening time reduced from 6.5 min per smear for CP to 2.2 min in EP smears.

Conclusion:
EP provides monolayered cervical smears with vivid morphological details, leading to reduced screening time and relatively higher pick-up of infections and low-grade cervical lesions as compared to conventional smears. The availability of such low-cost devices may enable wider application of cytology-based cervical cancer screening in low-resource countries.

RobHand es un sistema de neuro-rehabilitación para la mano de sujetos que han sufrido un ACV y deben recuperar la movilidad perdida como consecuencia del mismo. El sistema incluye un exoesqueleto de mano, un interfaz con el paciente para la realización de terapias basadas en un entorno virtual y un sistema de gestión de toda la información asociada a los pacientes y las terapias. Es un desarrollo financiado por el CDTI y se lleva a cabo en colaboración por la empresa CyL ImasD (Salamanca), el grupo de Robótica Médica del ITAP (UVa) y el servicio de rehabilitación del Hospital Clínico Universitario (HCU) de Valladolid. Soporta tanto terapias de tipo pasivo, en las cuales el sujeto no ejerce ninguna fuerza y toda la responsabilidad es del sistema, como otras de tipo activo asistido en las que se busca conseguir un comportamiento de tipo asistencia a medida (assist as needed) en el que el sistema detecta la fuerza realizada por el paciente y la complementa hasta el nivel de desempeño deseado. El trabajo presenta el planteamiento y el estado de desarrollo de la arquitectura de control del sistema. Está adopta un esquema jerárquico en tres niveles de los que el nivel intermedio L2 implementa una estrategia de interacción háptica con control de admitancia. Para ello planteamos utilizar registros de EMGs del paciente y el consumo de corriente de los motores para adaptar dinámicamente el nivel de asistencia a la situación del paciente. Se ha desarrollado un hardware específico para el registro y tratamiento de las señales de EMG y los algoritmos de control se ejecutan en un DSP para favorecer la autonomía del dispositivo. En la actualidad se están realizando pruebas de las terapias pasivas con 5 pacientes en el HCU y en breve comenzarán las pruebas con terapias activas.
How everyday ethics becomes a moral economy, and vice versa
Authors: Keane Webb 
Published: November 2019

Abstract
Unrealistic assumptions underlying neo-classical economic theory have been challenged by both behavioral economics and studies of moral economy. But both challengers share certain features with neo-classical theory. Complementing them, recent work in the anthropology of ethics shows that economic behavior is not reducible to either individual psychology or collective norms. This approach is illustrated with studies of transactions taking place at the borders between market rationality and ethically fraught relationships among persons—organ donation and sex work. The paper argues that the inherent value accorded to social relations tends to resist instrumentalization and that the biases that dealing with other people introduce into reasoning are not flaws but part of the core functions of rationality.

Published: November 2019

O presente estudo propõe-se a examinar em que medida os países que compõem a América Latina e o Caribe integram a mobilidade humana no contexto da mudança climática em suas legislações nacionais, contribuindo para a redução, prevenção e melhor gerenciamento de deslocamentos desse gênero em âmbito regional. Por meio do método dedutivo, busca-se inicialmente compreender os principais entraves à regulamentação jurídica do tema. Além da multicausalidade dos processos migratórios, a dificuldade em se determinar o número exato de indivíduos que se deslocam por conta da mudança do clima e a ausência de terminologias apropriadas são analisadas.	Na sequência, examina-se o aparato normativo que aborda a temática no regime climático internacional, com especial enfoque nas disposições das Conferências das Partes (COPs) que sucederam a Convenção-Quadro das Nações Unidas sobre a Mudança do Clima (CQNUMC), de 1992, e culminaram na instituição do Mecanismo Internacional de Varsóvia sobre Perdas e Danos (WIM) e no estabelecimento de uma Força-Tarefa sobre Deslocamento (TFD).	Por fim, investiga-se a incorporação da mobilidade humana nos documentos oficiais que devem ser submetidos pelos Estados-Partes à CQNUMC – como os Planos Nacionais de Adaptação (PNAs) e as Contribuições Nacionalmente Determinadas (CNDs) – das 34 nações latino-americanas e caribenhas, assim como legislações nacionais que regulamentam a mitigação e a adaptação aos efeitos adversos da mudança climática em âmbito interno. Verifica-se, neste momento, em que grau a região encontra-se alinhada e em consonância com as diretrizes e recomendações internacionais que abordam o tema, possibilitando também a identificação de lacunas e inconsistências.
A typical weather pattern for ozone pollution events in North China
Authors: Gong Cheng , Liao Hong 
Published: November 2019

Abstract. Ground-level observations, reanalyzed meteorological
fields and a 3-D global chemical and transport model (GEOS-Chem) were
applied in this study to investigate ozone (O3) pollution events (OPEs)
in North China (36.5–40.5∘ N, 114.5–119.5∘ E) during 2014–2017. Ozone pollution days (OPDs) were
defined as days with maximum daily averaged 8 h (MDA8) concentrations over
North China larger than 160 µg m−3, and OPEs were defined as
periods with 3 or more consecutive OPDs. Observations showed that there were
167 OPDs and 27 OPEs in North China during 2014–2017, in which 123 OPDs and
21 OPEs occurred from May to July. We found that OPEs in North China occurred
under a typical weather pattern with high daily maximum temperature (Tmax),
low relative humidity (RH), anomalous southerlies and divergence in the
lower troposphere, an anomalous high-pressure system at 500 hPa, and an
anomalous downward air flow from 500 hPa to the surface. Under such a
weather pattern, chemical production of O3 was high between 800 and 900 hPa, which was then transported downward to enhance O3 pollution at the
surface. A standardized index I_OPE was defined by applying
four key meteorological parameters, including Tmax, RH, meridional winds at
850 hPa (V850) and zonal winds at 500 hPa (U500). I_OPE can
capture approximately 80 % of the observed OPDs and OPEs, which has
implications for forecasting OPEs in North China.
Déficit ou diferença? um estudo sobre o autismo em pesquisas educacionais
Authors: Wuo Andrea Soares , Yaedu Fabiana Batista , Wayszceyk Sheila 
Published: November 2019

O autismo foi identificado por volta de 1940 e desde essa época sua abordagem pauta-se em critérios diagnósticos que o explicam a partir de dificuldades, déficits ou atrasos, de acordo com o modelo médico. A partir dos anos 2000, surgem outros modos de pensar o autismo, como o movimento da neurodiversidade, com o intuito de superar as dicotomias entre o normal e o patológico e compreender o autismo como diferença. Com base nos estudos críticos sobre o autismo, este artigo buscou identificar, por meio de revisão de literatura, as explicações sobre autismo em teses e dissertações sobre inclusão escolar, produzidas entre 2008 e 2018. Foram encontradas 106 produções, 53 relacionadas à área da educação e 22 que compuseram o corpus desse artigo. As pesquisas foram categorizadas a partir de dois modelos: médico e crítico. Os resultados revelam que a maioria dos estudos se orienta pelo modelo médico e, dentre aqueles que se inserem na categoria “modelo crítico”, as explicações perpassam diferentes abordagens teóricas, como a fenomenologia, a psicologia histórico-cultural e a psicanálise. Analisar as pesquisas trouxe uma multiplicidade de narrativas sobre o autismo e a percepção de que cabe romper com a naturalização dos discursos e a hierarquização das ciências naturais sobre as humanas, garantindo reconhecimento do outro como sujeito de direito e ator social.

AbstractAqueous zinc ion batteries (AZIBs), which have attracted attentions in the field of energy storage, is affected by dendrites and side reactions of Zn anode, resulting in an unsatisfactory performance of AZIBs. Herein, we propose a biased adsorption strategy mediated by straight‐chain molecule (Scm) for stabilizing Zn anode. The dual polar termini of Scms guaranties securely anchor themselves in a parallel orientation upon the Zn anode surface. This provides a comprehensive coverage, effectively sequestering water molecules from the Zn anode and precipitating the formation of a water‐depleted electric double layer (EDL). Furthermore, the Scms selectively adsorb along the crystallographic planes, guiding the deposition of Zn2+. Consequently, the incorporation of these Scms successfully mitigates anode corrosion, HER, and dendrites. The Zn||Zn, Zn||Cu and Zn||V6O13 cells with Scms display significantly enhanced electrochemical performance, especially at elevated temperature of 60 °C. This work highlights the potential of cost‐effective, straight‐chain electrolyte additives for enhancing Zn anode stability.

Published: December 2024

AbstractIt is essential for the development of highly efficient polymeric photocatalysts for hydrogen peroxide (H2O2) production. Nevertheless, the non‐uniform molecular structures and sluggish reaction pathway of polymeric photocatalysts lead to low conversion efficiency. In this work, we report sulfur‐contained phenolic resins with regulated conjugation for photocatalytic H2O2 production. Due to the substitution of sulfur for methylene in the phenolic resin structure, the conjugation degree of the material is adjusted, resulting in the formation of a built‐in electric field. This effectively enhances the charge separation capability, enabling charge carriers to react faster with substrates. Through in situ characterization and theoretical calculations, we have unveiled that the introduction of sulfur can modulate the reaction pathway of phenolic resin materials, enabling a dual‐pathway photocatalytic H2O2 production mediated by non‐radical species. Impressively, the sulfur‐contained resin photocatalyst showcases exceptional H2O2 production activity with a solar‐to‐chemical conversion efficiency of 1.4 % exceeding most reported systems, and generates 25 mmol m−2 of H2O2 under natural sunlight through large‐scale equipment. This work provides a facile strategy to separate the photogenerated electron–hole pairs of polymer photocatalysts to achieve efficient artificial photosynthesis.

AbstractIntroductionBiliary tract cancers (BTC) are rare and aggressive neoplasms. The current management of locally advanced or unresectable BTC is primarily based on chemotherapy (CHT) alone, linked to a median overall survival (OS) of approximately 12 months. However, international guidelines still consider concurrent chemoradiation (CRT) as an alternative treatment option. This study aims to review the current evidence on “modern” CRT for primary or recurrent unresectable BTC.Materials and MethodsA comprehensive search was conducted on PubMed, Scopus, and Cochrane Library to identify relevant papers. Prospective or retrospective trials reporting outcomes after concurrent CRT of unresectable non‐metastatic, primary, or recurrent BTC were included. Only English‐written papers published between January 2010 and June 2022 were considered.ResultsSeventeen papers, comprising a total of 1961 patients, were included in the analysis. Among them, 11 papers focused solely on patients with primary unresectable BTC, while two papers included patients with isolated local recurrences and four papers encompassed both settings. In terms of tumor location, 12 papers included patients with intrahepatic, extrahepatic, and hilar BTC, as well as gallbladder cancer. The median CRT dose delivered was 50.4 Gy (range: 45.0–72.6 Gy) using conventional fractionation. Concurrent CHT primarily consisted of 5‐Fluorouracil or Gemcitabine. The pooled rates of 1‐year progression‐free survival (PFS) and OS were 40.9% and 56.2%, respectively. The median 1‐ and 2‐year OS rates were 63.1% and 29.4%, respectively. Grade ≥3 acute gastrointestinal toxicity ranged from 5.6% to 22.2% (median: 10.9%), while grade ≥3 hematological toxicity ranged from 1.6% to 50.0% (median: 21.7%).ConclusionConcurrent CRT is a viable alternative to standard CHT in patients with locally advanced BTC, offering comparable OS and PFS rates, along with an acceptable toxicity profile. However, prospective trials are needed to validate and further explore these findings.

Published: December 2024

ABSTRACTThe Hepatitis B vaccine's safety profile is considered safe, but sometimes neurological complications, like Bell's palsy (acute peripheral facial neuropathy), can occur after its administration. A 35‐year‐old female doctor experienced left‐sided facial weakness and paralysis six days after getting the Hepatitis B vaccine. On examination, she had lower motor neuron facial nerve palsy. After excluding other causes, a diagnosis of Bell's palsy was made following Hepatitis B vaccine. She was treated with corticosteroids, antiviral medication, and physiotherapy, which led to a complete resolution over four weeks. Bell's palsy is still an uncommon potential side effect even though the advantages of the Hepatitis B vaccination exceed the risks. Further investigation is necessary to prove a conclusive link between the vaccine and its neurological side effects.

AbstractThe substantial moisture content of lignite imposes considerable constraints on its deep processing and subsequent utilization. A deep eutectic solvent (DES), synthesized from choline chloride (ChCl) and zinc chloride (ZnCl₂), was used to upgrade lignite under thermal treatment conditions. The effects of the DES molar ratio and its addition on the physicochemical and combustion characteristics of lignite were systematically analyzed at 280°C. The results demonstrated that the moisture content of lignite decreased from 22.63% to 5.18%, and then to 6.05%, as the molar ratio of DES was adjusted from 1:1 to 1:3, with the addition of 3 g of DES. This suggests that a DES molar ratio of 1:1 is more effective for lignite upgrading. As the DES addition increased from 1 g to 3 g, the moisture content of lignite decreased from 9.19% to 5.18%. As the molar ratio of ZnCl₂ in DES increased, the maximum combustion rate (Vmax) and ignition index (C) of the upgraded coal sample gradually decreased, indicating that lignite upgraded with DES at a 1:1 molar ratio exhibited good combustion performance. The sample treated with 3 g of DES demonstrated the best overall combustion characteristic index (S = 1.8), optimal ignition index (C), and combustion index (Rj), when the DES addition increased from 1 g to 3 g. Compared to raw coal, the activation energy of the upgraded lignite was lower (Eₐ = 63.99 kJ/mol), indicating enhanced combustion reactivity.

ABSTRACTThe development of the brain's vascular system is a predominantly prenatal process in mammalian species and is required for neurogenesis and further brain development. Our recent work on fetal pig has revealed that many neurodevelopmental processes start well before birth and proceed rapidly reaching near‐mature status already around birth. Here, we analyzed the development of neocortical vasculature from embryonic day (E) 45 onward (gestation in pig lasts 114 days) using qualitative and quantitative image analyses and protein blots. In all cortical layers, vessel volume from total brain volume at E100 resembled that of a postnatal day (P) 30 piglet. Endothelial cells expressed the tight junction protein claudin‐5 from E45 onward. GFAP+ and AQP4+ astrocytes, PDGFRβ+ pericytes, and α‐SMA+ smooth muscle cells are detectable near vessels at E60 suggesting an early assembly of blood–brain barrier components. The vascular system in the visual cortex is advanced before birth with an almost mature pattern at E100. Findings were confirmed by blots that showed a steady increase of expression of tight junction and angiogenesis‐related proteins (claudin‐5, occludin, VE‐cadherin, PECAM‐1/CD31) from E65 onward until P90. The expression profile was similar in visual and somatosensory cortex. Together, we report a rapid maturation of the vascular system in pig cortex.
