En este artículo se presenta el diseño del CANSAT Heliospectrum[1] desarrollado para su aplicación en percepción remota y análisis de imágenes para competir en el concurso anual realizado por la Sociedad de Sistemas Electrónicos y Aeroespaciales (AESS), capítulo Colombia. El equipo Helios, desarrollador del CANSAT, hace parte del grupo de investigación ASTRA de la Universidad de Antioquia. El diseño se realizó siguiendo las restricciones impuestas por el concurso, en las cuales el picosatélite debía asemejarse a una radiosonda con transmisores, componentes electrónicos, sensores con medición de aceleraciones, presión atmosférica, temperatura, campos magnéticos y aptitud para volar a 1.000 metros de altura (como mínimo), caer libremente y aterrizar con la ayuda de un paracaídas. Así mismo, cumple con los requerimientos necesarios para hacer del CANSAT una plataforma multipropósito con énfasis en percepción remota para aplicación en agricultura de precisión. Se implementó una cámara RGB como carga útil que, con ayuda de un algoritmo de análisis de imágenes que implementa el Excess Green Index (ExG) y el espacio de color Hue, Saturation, Value (HSV), permitió obtener resultados cualitativos de índices de vegetación. El CANSAT está conceptualizado en cinco subsistemas: computadora de vuelo, telemetría, estructura, descenso y recuperación, y potencia. En la aviónica del picosatélite se encuentran componentes principales como el microcontrolador Teensy 3,5, GPS GY-NEO6MV2, IMU GY-89 y en el sistema de recuperación un paracaídas expulsado con un servomotor. El prototipo de CANSAT fue fabricado y probado con éxito por el equipo, resultando ganador de la categoría “Cóndores” de la competencia CANSAT Colombia de la AESS.

Capsular Closure Following Hip Arthroscopy for Femoroacetabular Impingement
Authors: Economopoulos Kostas J. , Chhabra Anikar , Hassebrock Jeffrey D. , Kweon Christopher 
Published: November 2021

Background:
Recent literature has suggested that capsular closure following hip arthroscopy restores native hip-joint kinematics and may lead to better patient-reported outcomes, especially in high-level athletes
1–4
.

Description:
Capsular closure of the hip occurs following standard hip arthroscopy, which typically includes labral repair and osteoplasty of the femoral neck and/or acetabulum accessed through an interportal capsulotomy. Viewing through an anterolateral portal with use of a 70° scope, a suture-passing device loaded with a #2 FiberWire (Arthrex) is passed down into the mid-anterior portal. The suture is then passed through the anterior aspect of the proximal leaflet of the capsulotomy. The suture-passing device is then passed through the distal leaflet, and the previously passed suture is grasped and brought out of the cannula. The capsular bites are typically made 1 cm from the edge of the capsule. This process is repeated 1.5 cm posteriorly to the initially placed suture. Typical capsular closure takes 2 to 3 sutures for complete closure. Once the sutures are passed, they are tied with use of half-hitches and excess suture is cut.

Alternatives:
Alternatives include capsular plication, which is more frequently performed in the setting of capsular laxity preoperatively or connective-tissue disorders
5,6
. Additionally, there is evidence suggesting that leaving the capsulotomy unrepaired may lead to similar results in select populations
7
.

Rationale:
This procedure is performed largely secondary to the restoration of native anatomy and kinematics of the hip joint
3,8
. Arthroscopy of the hip requires a capsulotomy in order to access the joint, unlike other, more superficial joints such as the shoulder. Capsular closure is often technically challenging and adds length to the procedure. However, recent literature has shown improved patient-reported outcomes with routine capsular closure specifically among high-level athletes
9,10
.

Expected Outcomes:
Routine capsular closure has been associated with good mid-term patient-reported outcomes
10
. Patients who undergo hip arthroscopy and routine capsular closure can expect to meet the minimal clinically important difference and the patient acceptable symptomatic state for the modified Harris hip score and the Hip Outcome Score Activities of Daily Living component. Patients who participate in high-level sports activities may experience a quicker return to play and more normal kinematics with routine capsular closure.

Important Tips:

Clear off the capsule immediately following the capsulotomy.Utilize an over-the-top view to better visualize the capsule.Place the sutures from anterior to posterior.
Identification of spatial co-expression patterns and intra-tissue heterogeneity in spatially resolved transcriptomics by region-specific denoising
Authors: Wang Linhua , Liu Zhandong 
Published: November 2021

Abstract
We are pleased to introduce a first-of-its-kind tool that combines in-silico region detection and missing value estimation for spatially resolved transcriptomics. Spatial transcriptomics by 10X Visium (ST) is a new technology used to dissect gene and cell spatial organization. Analyzing this new type of data has two main challenges: automatically annotating the major tissue regions and excessive zero values of gene expression due to high dropout rates. We developed a computational tool—MIST—that addresses both challenges by automatically identifying tissue regions and estimating missing gene-expression values for each detected region. We validated MIST detected regions across multiple datasets using manual annotation on the histological staining images as references. We also demonstrated that MIST can accurately recover ST’s missing values through hold-out experiments. Furthermore, we showed that MIST could identify intra-tissue heterogeneity and recover spatial gene-gene co-expression signals. We therefore strongly encourage using MIST before downstream ST analysis because it provides unbiased region annotations and enables accurately denoised spatial gene-expression profiles.

Published: November 2021

Abstract
Radon is soluble in water, and the radon in drinking water is one of the sources of indoor radon. The China national standard for drinking water (GB5749-2006) indicates that the radon concentration in drinking water cannot be higher than 300pCi/L. The widely used method for measuring radon concentration in water is to use the RAD7 and the H2O accessory which provided by the Durridge Company for bubbling measurement. There are two kind sample bottles: 40ml and 250ml; the measurement steps: bubbling for 5 minutes, and measuring for 20 minutes. For the 40ml sample volume the conversion coefficient is around 25. For the 250ml sample volume the conversion coefficient is around 4. Since the price of the accessory is more than one thousand dollars, and the drying tube of the accessory is small, it needs to be replaced after each measurement which makes the operation is troublesome. We used a big drying tube to perform the radon concentration in water measurement. A new model for description the radon concentration in the gas circuit is proposed, and the conversion coefficient in any measurement condition is obtained. Any volume of sample bottle and drying tube can be used, selecting the suitable bubbling time and measuring time, the radon concentration in water can be obtained.

Abstract
Deep learning is a rapidly growing research area having state of art achievement in various applications including but not limited to speech recognition, object recognition, machine translation, and image segmentation. In the current modern industrial manufacturing system, Machine Health Surveillance System (MHSS) is achieving increasing popularity because of the widespread availability of low cost sensors internet connectivity. Deep learning architecture gives useful tools to analyze and process these vast amounts of machinery data. In this paper, we review the latest deep learning techniques and their variant used for MHSS. We used Gearbox Fault Diagnosis dataset in this paper that contains the sets of vibration attributes recorded by SpectraQuest’s Gearbox Fault Diagnostics Simulator. In addition, the authors used the variant of auto encoders for feature extraction to achieve higher accuracy in machine health surveillance. The results showed that the bagging ensemble classifier based on voting techniques achieved 99% accuracy.

Published: November 2021

Abstract
Research-ready data (that curated to a defined standard) increases scientific opportunity and rigour by integrating the data environment. The development of research platforms has highlighted the value of research-ready data, particularly for multi-cohort analyses. Following user consultation, a standard data model (C-Surv), optimised for data discovery, was developed using data from 12 Dementias Platform UK (DPUK) population and clinical cohort studies. The model uses a four-tier nested structure based on 18 data themes selected according to user behaviour or technology. Standard variable naming conventions are applied to uniquely identify variables within the context of longitudinal studies. The data model was used to develop a harmonised dataset for 11 cohorts. This dataset populated the Cohort Explorer data discovery tool for assessing the feasibility of an analysis prior to making a data access request. It was concluded that developing and applying a standard data model (C-Surv) for research cohort data is feasible and useful.

Published: November 2021

Abstract
The optical biosensor is the emerging research area in the field of bio-photonics. The black phosphorus zinc sulfide-based hybrid configuration is suitable for implementing and analyzing ultrasensitive biosensors. Ag/Zinc sulfide/silicon dioxide/black phosphorus-based biosensor has been implemented in the proposed work using the modified Kretschmann configuration. The sensitivity improvement of the designed SPR sensor is analyzed in the different arrangements of the layers. The thickness of the layers of all the materials has been optimized. The thickness of the Ag metal layer is optimized and taken as 45 nm. The sensitivity and quality factor measured here is as high as \(664.6^\circ /\text{R}\text{I}\text{U}\) and 200 at 1.37 refractive index—the P-polarized light source of \(633\text{n}\text{m}\) wavelength. The proposed biosensor confirms tremendous growth in terms of sensitivity, detection accuracy, and quality factor compared with the traditional SPR sensors. Zinc sulfide has multiple applications in the sensing fields, like sensors based on UV rays, lasers, and gas.

Abstract
Nanomaterials improve the physical and electronic characteristics of polymer matrices, allowing the matrices to be used as low cost, easy to handle sensors. Nano ZnO oxide is forming nanocomposite with PVA modified with graphene. Rather than ZnO other metal oxides are assumed to enhance the electronic properties of PVA modified with graphene (G). Accordingly, Density Function Theory (DFT) was used to analyze model molecules of Polyvinyl Alcohol (PVA) that improved with various metal oxides and graphene quantum dots (GQDs). To show the influence of nanomaterials on PVA matrix behavior, HOMO/LUMO molecular orbitals and Molecular Electrostatic Potential (MESP) mapping were calculated. The B3LYPL/LAN2DZ model was used to calculate the band gap energy ∆E, total dipole moment (TDM), and Molecular Electrostatic Potential (MESP). The obtained results indicated that PVA interacted with MgO, led to a significant improvement in the electrical characteristics. The incorporation of GQDs into PVA/MgO resulted in a novel nanocomposite with good electrical characteristics and a band gap energy ∆E of 0.201 eV, which is intended to be used as a humidity sensor.
Analytic conformal bootstrap and Virasoro primary fields in the Ashkin-Teller model
Authors: Nemkov Nikita , Ribault Sylvain 
Published: November 2021

We revisit the critical two-dimensional Ashkin–Teller model, i.e. the
\mathbb{Z}_2ℤ2
orbifold of the compactified free boson CFT at
c=1c=1.
We solve the model on the plane by computing its three-point structure
constants and proving crossing symmetry of four-point correlation
functions. We do this not only for affine primary fields, but also for
Virasoro primary fields, i.e. higher twist fields and degenerate fields.
This leads us to clarify the analytic properties of Virasoro conformal
blocks and fusion kernels at c=1c=1.
We show that blocks with a degenerate channel field should be computed
by taking limits in the central charge, rather than in the conformal
dimension. In particular, Al. Zamolodchikov’s simple explicit expression
for the blocks that appear in four-twist correlation functions is only
valid in the non-degenerate case: degenerate blocks, starting with the
identity block, are more complicated generalized theta functions.

Authors: Herina Clara 
Published: November 2021

Some private universities in Jakarta use TOEFL or TOEFL-like test as the admission requirement for new students. Therefore, students’ candidates should prepare well to achieve the minimum score for being admitted. Unfortunately, their high school did not give enough training in doing the TOEFL test. The purpose of this community development program is to train high school students to do TOEFL test, especially the Reading section. The participants of the program were seven 12th grade high school students who were included in ASAK Paroki MKK community. They were trying to qualify for admission in Binus University. The program was created in the form of classroom teaching and individual assignment. In this program, we taught them about the TOEFL Reading test types, strategies, and tips for doing the test. After the training, the students reported their understanding of TOEFL and confidence in preparing the university admission test.

Authors: Wu Wenzhu , Guo Min , Shi Lili , Zhou Yueguang 
Published: November 2021

Abstract
An arsenic-contamination survey was conducted in Lake Datunhai in Southwest China, which is contaminated by arsenic. The arsenic-contaminated soil was selected and arsenic adsorption on the soil solid in the polluted water was studied through field investigation and laboratory experiments. The results showed that the red soil in survey area contained a relatively large amount of arsenic in the range of 36.41–153.52 mg/kg, which is higher than the National Soil Environmental Quality Standard Grade III. The arsenic pollution in the surveyed lake was relatively serious, as the amount of arsenic contained in the water of Lake Datunhai was between 0.23 and 0.663 mg/L. The amount of arsenic in the sediment was between 273 and 755 mg/kg. The results of laboratory adsorption experiments with different soils showed that when the ratio of soil and water was 3.5/1000, the amount of arsenic in the water sample taken from the lake reduced from 0.3 mg/L to 0.03 mg/L, which would satisfy the Water Quality Standard Grade III (below 0.05 mg/L). The selected red soil was relatively effective for arsenic absorption. Based on theoretical calculations, the thickness of sediment would increase by about 0.95 cm by applying fixed arsenic solid on arsenic-polluted water treatment.
