Habitability and Spectroscopic Observability of Warm M-dwarf Exoplanets Evaluated with a 3D Chemistry-Climate Model
Authors: Chen Howard , Wolf Eric T. , Zhan Zhuchang , Horton Daniel E. 
Published: November 2019

Abstract
Planets residing in circumstellar habitable zones offer us the best opportunities to test hypotheses of life’s potential pervasiveness and complexity. Constraining the precise boundaries of habitability and its observational discriminants is critical to maximizing our chances at remote life detection with future instruments. Conventionally, calculations of the inner edge of the habitable zone (IHZ) have been performed using both 1D radiative-convective and 3D general circulation models. However, these models lack interactive 3D chemistry and do not resolve the mesosphere and lower thermosphere region of the upper atmosphere. Here, we employ a 3D high-top chemistry-climate model (CCM) to simulate the atmospheres of synchronously rotating planets orbiting at the inner edge of habitable zones of K- and M-dwarf stars (between T
eff = 2600 and 4000 K). While our IHZ climate predictions are in good agreement with general circulation model studies, we find noteworthy departures in simulated ozone and HOx photochemistry. For instance, climates around inactive stars do not typically enter the classical moist greenhouse regime even with high (≳10−3 mol mol−1) stratospheric water vapor mixing ratios, which suggests that planets around inactive M-stars may only experience minor water-loss over geologically significant timescales. In addition, we find much thinner ozone layers on potentially habitable moist greenhouse atmospheres, as ozone experiences rapid destruction via reaction with hydrogen oxide radicals. Using our CCM results as inputs, our simulated transmission spectra show that both water vapor and ozone features could be detectable by instruments NIRSpec and MIRI LRS on board the James Webb Space Telescope.

Abstract
We report a systematic survey of a 6.7 GHz Class II methanol maser toward a sample of 448 sources selected from the Red Midcourse Space Experiment Source catalog. These sample sources are composed of high-mass star-forming region (HMSFR) candidates and have been studied as tracers of HMSFRs, such as water masers or radio continuum emission of ultracompact H ii region. The survey was conducted using the Shanghai Tianma Radio Telescope. Through the observations, we simultaneously studied the 4.7 and 6.0 GHz excited-state interstellar hydroxyl (OH) maser lines and 10 hydrogen radio recombination lines (RRLs) in the C band. In total, we detected 6.7 GHz methanol masers and RRLs from 102 and 116 sources, respectively. In addition, 4, 3, and 10 sources exhibit OH masers at 4765.56, 6030.75, and 6035.09 MHz transitions, respectively. Through the survey, we identified four new 6.7 GHz methanol maser sources and three new excited-state OH maser sources (one at 4750 MHz and two at 6035 MHz). The statistical analysis demonstrated that there is a positive correlation of luminosity between 6.7 GHz methanol masers and RRLs. A good correlation of integrated luminosity between radio continuum emission and the 6.7 GHz methanol masers is presented with respect to the RRL emission sources. The average of the integrated luminosities of the RRLs in the sources with 6.7 GHz masers is greater than those without the 6.7 GHz masers; similarly, the average of integrated luminosities of the 6.7 GHz methanol masers in the sources with RRLs is greater than those without the RRLs. Moreover, we found that the averages of the emission measure and electron temperature of H ii regions associated with 6.7 GHz methanol masers are larger than those without the 6.7 GHz methanol masers. This suggests that the masers are most likely produced in high gas density and luminous regions with brighter RRLs and higher radio continuum emission.

Abstract
We analyze Brans–Dicke gravity with a cosmological constant, Λ, and cold dark matter (BD-ΛCDM) in the light of the latest cosmological observations on distant supernovae, Hubble rate measurements at different redshifts, baryonic acoustic oscillations, large-scale structure formation data, gravitational weak-lensing, and the cosmic microwave background under full Planck 2015 cosmic microwave background likelihood. Our analysis includes both the background and perturbations equations. We find that BD-ΛCDM is observationally favored as compared to the concordance ΛCDM model, which is traditionally defined within General Relativity (GR). In particular, some well-known persisting tensions of the ΛCDM with the data, such as the excess in the mass fluctuation amplitude

and especially the acute H
0-tension with the local measurements, essentially disappear in this context. Furthermore, viewed from the GR standpoint, BD-ΛCDM cosmology mimics quintessence at

L’influence du tabac sur la mortalité en Europe
Authors: Janssen Fanny 
Published: November 2019

En Europe, l’épidémie de tabac a influé sur les niveaux et tendances de la mortalité, ainsi que sur les différences entre les sexes et entre les pays. En 2014, le tabac réduit l’espérance de vie des hommes de 2,7 ans en moyenne et celle des femmes de 1,0 an. Le tabac explique 28 % de l’écart d’espérance de vie entre les sexes. L’épidémie de tabac est la plus avancée dans le Nord-Ouest de l’Europe. L’effet du tabac y est en recul chez les hommes, mais n’a pas encore atteint son pic chez les femmes, et leurs mortalités dues au tabac sont proches. Sans le tabac, l’espérance de vie n’aurait pas stagné dans des pays comme le Danemark et les Pays-Bas chez les hommes dans les années 1950-1960, et chez les femmes dans les années 1980-1990. Elle aurait augmenté en général de façon plus importante, et les évolutions des hommes et des femmes auraient été plus proches.
An Efficient Probability Estimation Decision Tree Postprocessing Method for Mining Optimal Profitable Knowledge for Enterprises with Multi-Class Customers
Authors: Naga Muneiah JanapatyI , SubbaRao Ch D V 
Published: November 2019

Enterprises often classify their customers based on the degree of profitability in decreasing order like C1, C2, ..., Cn. Generally, customers representing class Cn are zero profitable since they migrate to the competitor. They are called as attritors (or churners) and are the prime reason for the huge losses of the enterprises. Nevertheless, customers of other intermediary classes are reluctant and offer an insignificant amount of profits in different degrees and lead to uncertainty. Various data mining models like decision trees, etc., which are built using the customers’ profiles, are limited to classifying the customers as attritors or non-attritors only and not providing profitable actionable knowledge. In this paper, we present an efficient algorithm for the automatic extraction of profit-maximizing knowledge for business applications with multi-class customers by postprocessing the probability estimation decision tree (PET). When the PET predicts a customer as belonging to any of the lesser profitable classes, then, our algorithm suggests the cost-sensitive actions to change her/him to a maximum possible higher profitable status. In the proposed novel approach, the PET is represented in the compressed form as a Bit patterns matrix and the postprocessing task is performed on the bit patterns by applying the bitwise AND operations. The computational performance of the proposed method is strong due to the employment of effective data structures. Substantial experiments conducted on UCI datasets, real Mobile phone service data and other benchmark datasets demonstrate that the proposed method remarkably outperforms the state-of-the-art methods.
Comparación de la normalización lineal de la escala de tiempos con el registro funcional continuo en movimientos cíclicos del cuello
Authors: Page Alvaro , López Noelia , Venegas William Ricardo , Serra Pilar 
Published: November 2019

La normalización de la escala de tiempos es un paso necesario para aplicar las técnicas de análisis de datos funcionales al estudio de los movimientos humanos. La técnica estándar es la normalización lineal que, a pesar de su sencillez, puede ser ineficaz para reducir la variabilidad en la duración de los eventos [1]. Una alternativa es el registro continuo que supone ajustar de forma no lineal la escala de tiempos [2]. En este caso, la información temporal se mantiene en las funciones warping, que relacionan el tiempo modificado frente al promedio. No obstante, este procedimiento es complejo y computacionalmente costoso. Además, se ha señalado que en movimientos cíclicos como el de masticación apenas hay diferencias entre métodos [3]. En este trabajo se comparan ambos métodos en el caso del movimiento cíclico de flexo-extensión del cuello, analizando las funciones ángulo y velocidad angular. A partir de una base de datos con 437 ciclos completos extensión-flexión de cuello, se han aplicado ambos tipos de normalización de la escala temporal. Se han analizado las diferencias en las curvas medias y las desviaciones típicas funcionales, cuyos valores medios e intervalos de confianza se han establecido mediante un proceso de bootstrapping. Los resultados muestran que apenas hay diferencias en las curvas medias obtenidas por ambos procedimientos, aunque sí en las desviaciones típicas funcionales, que son algo menores en el caso del registro no lineal. Por otra parte, los resultados obtenidos con el registro no lineal son diferentes cuando se usan las curvas de posición o las de velocidad como referencia para el reescalado. Estos resultados sugieren que el registro no lineal, aunque puede ser útil para el análisis de señales no periódicas o donde no haya que analizar a la vez funciones y sus derivadas, no ofrece ventajas importantes frente a la normalización lineal en el caso de los movimientos cíclicos.

Validación de los marcadores ArUco para el análisis de movimientos humanos
Authors: Page Álvaro , Jara Nicolás , Abad José Luis , Navarro José 
Published: November 2019

En los últimos años se han publicado numerosos trabajos sobre el empleo de técnicas de bajo coste para el análisis de movimientos humanos, especialmente mediante sensores inerciales [1]. Menos esfuerzos se han realizado en la línea de otras técnicas basadas en video-análisis, donde la mayoría de trabajos se refieren al análisis de movimientos planos con una cámara [2]. Sin embargo, en el campo de la robótica se vienen usando desde hace tiempo sistemas de posicionado mediante marcadores de realidad aumentada (AR). Estos sistemas permiten analizar, en tiempo real y con una única cámara de video, la posición y orientación de objetos con precisión suficiente para su uso en muchas aplicaciones biomecánicas [3]. En particular, la librería ARUCO [4] permite analizar movimientos de varios marcadores de manera rápida y eficiente, lo que permite aplicarlos al análisis de varios segmentos corporales en tiempo real. En este trabajo se analiza la precisión de los marcadores ARUCO en la medida de ángulos y desplazamientos, comparando los movimientos medidos con el sistema con dos técnicas de precisión: encoders de desplazamientos lineales y giros, para las medidas estáticas, y un sistema de videofotogrametría de precisión, para las medidas en movimiento. Los resultados muestran que los marcadores pueden medir desplazamientos con errores estándar del orden de 1 mm en los desplazamientos paralelos al plano de la cámara y del orden de 3 mm en profundidad. Los errores angulares son inferiores a 0.5º en los giros en el plano de la cámara y del orden de 1º en los giros alrededor de ejes paralelos a dicho plano. Estos errores son mucho menores que los asociados a la variabilidad humana, por lo que sería posible utilizar este tipo de marcadores para numerosas aplicaciones biomecánicas.

Published: November 2019

El análisis de las señales cerebrales para la asistencia en pacientes con movilidad reducida es un área de investigación continua en la que las nuevas tecnologías ofrecen un amplio espectro de posibilidades para la ayuda activa como los exoesqueletos y las interfaces cerebro-maquinas (BMI). En este trabajo nos centramos en realizar una interfaz BMI para el control de velocidad del miembro inferior. El objetivo de este estudio es analizar las señales electroencefalográficas (EEG) para obtener un indicador que relacione la información cerebral con marcadores de velocidad en la marcha. Para el procesamiento de las señales EEG analizamos los ritmos sensoriomotores correspondientes a las bandas Alfa y Beta en la zona motora. La interfaz BMI debe discernir entre dos estados marcha e intención de cambiar de velocidad. La creación de dicho modelo requiere caracterizar el momento del cambio, para la fase de entrenamiento. Hemos utilizado el equipo de captura de movimiento Tech MCS V3 basado en sensores inerciales. Analizamos las componentes frecuenciales de la aceleración en el dominio temporal mediante la transformada continua Wavelet (CWT). En este trabajo realizamos un estudio menor para analizar la marcha y otro principal para la validación de la interfaz BMI planteada. Tres usuarios sanos participaron en el estudio. El protocolo tiene tres fases, el usuario espera parado unos segundos tras los cuales decide comenzar la marcha a un ritmo visiblemente lento y llegado un punto voluntariamente cambia de velocidad manteniéndola unos segundos. El experimento consta de 40 repeticiones. Debido a la gran generación de artefactos durante la marcha los componentes de la señal EEG fueron descompuestos mediante ICA y rechazados según su componente espectral y un criterio apropiado. Los resultados fueron procesados con varias configuraciones de electrodos de la zona motora, en diferentes bandas de frecuencia y con y sin eliminación de artefactos. El porcentaje máximo de acierto para los tres usuarios a la hora de distinguir entre las dos clases es del 58%, no siendo resultados lo suficientemente remarcables para poder validar de forma confiable la interfaz BMI planteada.
Pilates versus resistance training on trunk strength and balance adaptations in older women: a randomized controlled trial
Authors: Carrasco-Poyatos María , Ramos-Campo Domingo J. , Rubio-Arias Jacobo A. 
Published: November 2019

Background
The neuromuscular decline impact in the functional independence of older women is determining the necessity of implementing new strategies focused on core strength training and postural stability maintenance to promote healthy aging.

Objectives
To define whether Pilates or resistance training is better at improving (a) core isometric and isokinetic muscular strength, and (b) static and dynamic balance, in older women.

Methods
This was a cluster randomized controlled trial. Physically independent older women (60–80 years) from day centers were randomly allocated to Pilates, Muscular and Control Groups (PG, MG and CG) using a block randomization method. Only the research staff performing the assessment and statistical analysis were blinded. Exercise groups trained twice a week (1 h per session) for 18 weeks in a moderate-to-vigorous intensity. Core strength (primary outcome): trunk and hip isometric and hip isokinetic muscular strength (Biodex System III Pro Isokinetic Dynamometer), alongside one leg static balance (portable force platform Kistler 9286AA) and dynamic balance (timed up and go (TUG)) were assessed.

Results
A total of 60 participants were randomized (PG, n = 20; MG, n = 20; CG, n = 20) and 49 completed the trial (PG, n = 16; MG, n = 19; CG, n = 14). Regarding hip isometric extension strength, PG was statistically better than CG (P = 0.004). There were no differences between groups regarding isokinetic strength or balance. Intra-group comparisons showed significant improvements (P < 0.05) in the dynamic balance and trunk and hip isometric extension strength for PG and MG, whereas every hip isokinetic measurement was improved in MG. Exercise programs did not produce any adverse event.

Conclusions
The Pilates training program was more effective for improving isometric hip and trunk extension strength, while the Muscular training program generated greater benefits on trunk and hip isokinetic strength. Moreover, both training programs showed moderate effects for the TUG.

Clinical Trial Registration
The trial was registered at ClinicalTrials.gov (identifier: NCT02506491).
Sargon in Samaria
Authors: Aster Shawn Zelig 
Published: November 2019

How different were the claims of Assyrian royal inscriptions from actual Neo-Assyrian practice? This essay explores this question by examining two unusual claims made by Sargon II in relation to his rule of Samaria. The first claim, which appears both in the Khorsabad annals and in a Nimrud prism, should be translated “I again settled Samaria, more than (it had) previously (been settled).” Based on the historical reconstruction derived from archaeological data, I argue that this phrase refers to the movement of exiles into areas in the western part of the province of Samaria. These areas in the western part of the province, around the sites of Aphek, Hadid, and Gezer, experienced significant population increases in the Assyrian period. The second passage, in Sargon’s Great Display Inscription from Khorsabad, refers to Sargon’s treatment of non-deported Samaritans. It should be translated “I trained the remnant in their crafts.” The historical reality behind this claim is the shift in agricultural techniques and activities in Samaria as a result of the Assyrian conquest. The Assyrian domination of Samaria required the production of grain surpluses, which needed to be made available in the Aphek-Gezer region in the western part of the province of Samaria.
In each of the claims from the royal inscriptions examined in this essay, we see that the royal inscriptions credit the king with activities performed by the provincial governor. They change the description of the activity to make it “fit for royalty.”

Published: November 2019

AbstractThe developments of rationally designed binder‐free metal chalcogenides decorated flexible electrodes are of paramount importance for advanced energy storage devices. Herein, binder‐free patronite (VS4) flower‐like nanostructures are facilely fabricated on a carbon cloth (CC) using a facile hydrothermal method for high‐performance supercapacitors. The growth density and morphology of VS4 nanostructures on CC are also controlled by varying the concentrations of vanadium and sulfur sources along with the complexing agent in the growth solution. The optimal electrode with an appropriate growth concentration (VS4‐CC@VS‐3) demonstrates a considerable pseudocapacitance performance in the ionic liquid (IL) electrolyte (1‐ethyl‐3‐methylimidazolium trifluoromethanesulfonate), with a high operating potential of 2 V. Utilizing VS4‐CC@VS‐3 as both positive and negative electrodes, the IL‐based symmetric supercapacitor is assembled, which demonstrates a high areal capacitance of 536 mF cm−2 (206 F g−1) and excellent cycling durability (93%) with superior energy and power densities of 74.4 µWh cm−2 (28.6 Wh kg−1) and 10154 µW cm−2 (9340 W kg−1), respectively. As for the high energy storage performance, the device stably energizes various portable electronic applications for a long time, which make the fabricated composite material open up news for the fabrication of fabrics supported binder‐free chalcogenides for high‐performance energy storage devices.

Cancer Cell Membrane‐Camouflaged Micromotor
Authors: Zhang Hongyue , Li Zesheng , Wu Zhiguang , He Qiang 
Published: November 2019

AbstractA type of cancer cell membrane‐camouflaged and gold nanoshell‐functionalized CaCO3 (CGNCaCO3) micromotor and its ability to modulate immune activity are described. The process used to fabricate these micromotors includes the synthesis of CaCO3 particles, the functionalization of the gold nanoshell, and the fusion of cancer cell membrane vesicles onto the gold nanoshell‐functionalized CaCO3 (GNCaCO3) particles. Due to the benefit of the homotypic binding of the cancer cell membrane, the autonomous movement of CGNCaCO3 micromotors results in their substantial accumulation on cancer cells. The subcutaneous injection of CGNCaCO3 micromotors enhances their immune activity by camouflaging cancer cells. Such CGNCaCO3 micromotors inherit the biological features of natural cancer cells and are able to facilitate a broad range of antigenic and biological processes that common synthetic motors cannot achieve, and thus, these micromotors hold considerable promise for a number of practical biomedical uses.
