Contemporary Earthquake Hazards in the West-Northwest Himalaya: A Statistical Perspective through Natural Times
Authors: Pasari Sumanta , Sharma Yogendra 
Published: August 2020

AbstractHimalayan earthquakes have deep societal and economic impact. In this article, we implement a surrogate method of nowcasting (Rundle et al., 2016) to determine the current state of seismic hazard from large earthquakes in a dozen populous cities from India and Pakistan that belong to the west-northwest part of Himalayan orogeny. For this, we (1) perform statistical inference of natural times, intersperse counts of small-magnitude events between pairs of succeeding large events, based on a set of eight probability distributions; (2) compute earthquake potential score (EPS) of 14 cities from the best-fit cumulative distribution of natural times; and (3) carry out a sensitivity testing of parameters—threshold magnitude and area of city region. Formulation of natural time (Varostos et al., 2005) based on frequency–magnitude power-law statistics essentially avoids the daunting need of seismicity declustering in hazard estimation. A retrospective analysis of natural time counts corresponding to M≥6 events for the Indian cities provides an EPS (%) as New Delhi (56), Chandigarh (86), Dehradun (83), Jammu (99), Ludhiana (89), Moradabad (84), and Shimla (87), whereas the cities in Pakistan observe an EPS (%) as Islamabad (99), Faisalabad (88), Gujranwala (99), Lahore (89), Multan (98), Peshawar (38), and Rawalpindi (99). The estimated nowcast values that range from 38% to as high as 99% lead to a rapid yet useful ranking of cities in terms of their present progression to the regional earthquake cycle of magnitude ≥6.0 events. The analysis inevitably encourages scientists and engineers from governments and industry to join hands for better policymaking toward land-use planning, insurance, and disaster preparation in the west-northwest part of active Himalayan belt.

Abstract
Accurate monitoring of volcanic activity demands expertise in fields including geophysics, geology, and geochemistry. Data obtained from the most recent technical advances are particularly vital in pre-eruptive phases. In particular, seismic monitoring in near real time is essential to locating and discriminating early signs among different sources of seismic waves, especially those related to movement and overpressure in underground fluids. Among the major indicators of volcanic restlessness are fumaroles, or gas and steam vents, often located near a volcanic summit. Their activity could be monitored by seismometers in their vicinity, but today’s standard instruments cannot last very long when exposed to the high temperatures and the billowing, sulfurous, acidic gases near a fumarole. Conventional gear may also not be accessible for emergency deployment, or repair, even in pre-eruptive phases. La Soufrière de Guadeloupe Volcano in the Caribbean typifies such challenges. Its last significant event was a phreatic (gas and steam) eruption in 1976 that prompted evacuation of the archipelago’s nearby capital. Since early 2018, the 1467-meter-high stratovolcano has shown signs of increased activity. To provide a hardy, high-resolution monitoring system, we installed a recently developed type of seismometer just 10 m from a vigorous summit fumarole. The sensor is a purely opto-mechanical geophone that is interrogated through a 1.5 km fiber-optic cable by a remote, and thus it is a much safer optic-electronic system down the volcano’s flank. The ESEO Group and the Institut de Physique du Globe de Paris (IPGP) started development of this novel seismometer in 2008. The 2019 Guadeloupe installation is part of the HIgh PERformance SeISmometer (HIPERSIS) project (French Agence Nationale de la Recherche [ANR]). It is, to our knowledge, the first high-resolution optical seismometer ever installed on an active volcano or other active, hazardous zone. We report here the details of this installation, the means we are using for measurements, and our implementation strategy, and we share some of the first results. Such an optical seismometer, as well as a variety of other geophysical sensors built on the same principle, can be installed in a wide variety of sites with fibers up to 50 km long.

Population aging is an emerging issue of developed as well as developing countries. Cognitive impairment (CI) is defined as “confusion or memory loss that is happening more often or is getting worse during the past 12 months”. Depression is a mental state disorder characterized by persistent depressed mood or loss of interests in activities causing significant impairment in daily life. Regular physical activities, control of blood sugar and cholesterol can reduce the risk of both cognition and depression. Thus the objectives of the study were to find the prevalence of cognitive impairment and depression among elderly and to detect association between cognitive impairment and depression among elderly in urban filed practice area of Chitradurga.This cross sectional study was carried out in urban areas of Chitradurga, from February to April 2019.The study participants were geriatric age population with age more than or equal to 60 completed years. A sample size of 280 was obtained with sample prevalence being 58.9% and margin of error 10%. Data was collected using standardized pre-tested structured questionnaire, which included socio-demographic variables, mini mental state examination (MMSE) scale to detect cognitive impairment and geriatric depression scale (GDS) short version to identify depression. Data was entered & analyzed using SPSS 20. Chi- Square test was used. P value &#60;0.05 was considered significant.The prevalence of cognitive impairment and depression in the elderly was noted to be 33.6% and 60% respectively. Factors showing significant association with MMSE score included older age group, male gender, single/widowed status, and elderly belonging to lower socioeconomic status, joint family and illiteracy. The association between cognitive impairment and depression was found to be statistically significant with a p value of &#60;0.001.There is an association between cognitive impairment and depression. Therefore it is essential to screen elderly for depression scale while assessing cognitive impairment.

<p>A method for the measurements of the flow rate of high temperature molten slag using image identification was proposed. Image of molten slag could be acquired by high-speed camera. The flow rate of molten slag was calculated by the diameter, which was obtained by the edge detection, and the velocity of the feature points obtaining by threshold segmentation. Feature points could be found on the liquid column of molten slag by photo graphing, which showed that the method is feasible. Then glycerite was used to study the influences of different shooting parameters on the measurement accuracy. The effects of exposure time, frame rate and focal length on measurement accuracy were obtained. At the same time, it was found that the selection of location and length of feature region would also have a significant impact on the measurement accuracy.</p><p> </p>

Aldose reductase is an enzyme that catalyzes one of the steps in the sorbitol (polyol) pathway that is responsible for fructose formation from glucose. In diabetes, aldose reductase activity increases as the glucose concentration increases. The purpose of this research was to identify and develop the use of artemisinin as an anti-diabetic candidate through in silico studies, including reverse docking, receptor analysis, molecular docking, drug scan, absorption, and distributions and toxicity prediction of artemisinin. Based on the results, we conclude that artemisinin can be used as an anti-diabetic candidate through inhibition of aldose reductase

The consequences arising from the epidemic of corona diseases are felt by all religious adherents, countries, and people without the age limit. COVID 19 also comes through economic, political, social, and spiritual space. This virus also not only assaults physical but has disrupted the psychological health of many people. This study aims to discuss and propose several solutions that can be given related to the response due to COVID 19 through the Islamic counselling approach. This research is a literature review both in concept and the results of empirical studies. Data is collected through artificial intelligent search engines to find the right theme according to the survey within a specific time limit. The results of literature searches and phenomenological studies developed during the pandemic in this community have found that Islamic counselling can reduce the number of patients exposed to the virus. The virus can strike out the weak physical. The brittle physique is affected by a fragile mental condition. Therefore, Islamic counselling strengthens the psychological health that can enhance the body's resistance from corona disease through several stages.</p>
Nature of Degradation in Semiconductor Lasers with Electronic Energy Pumping. Theoretical Background

. Catastrophic degradation takes place in case of reaching critical values of laser radiation density power in semiconductor lasers with electronically pumped energy made from single crystals of some compounds. It has been accompanied by mechanical destruction of the surface at resonator ends, an irreversible decrease in radiation power and an increase in generation threshold. Moreover, during the catastrophic degradation of semiconductor lasers under the action of intrinsic radiation, significant changes in the crystal structure occur within the single crystal: dislocation density reaches a value more 1012–1015 cm–2. It has been shown that initial density of dislocations and critical power density of the intrinsic radiation are inversely proportional. Thus, the degradation process of semiconductor lasers is directly related to generation and multiplication of dislocations during laser operation. Mechanical destruction of a crystal lattice occurs at critical values of laser radiation power and dislocation density. To clarify the proposed mechanism for the degradation of semiconductor lasers, it is necessary to take into account an effect of dislocations on optical properties of semiconductors. Typically, this effect is considered as follows: dislocations cause an appearance of a local deformation field and, in addition, form space-charge regions that surround a dislocation core in the form of a charged tube. The paper proposes a model of the phenomenon under study: large stresses arise in the dislocation core, leading to a displacement of individual atoms and deformation of the crystal lattice. Lattice deformation in the dislocation core leads to a local change in the width of a forbidden band. This change value is about 10–2 eV for a screw dislocation and 10–1 eV for a boundary dislocation. The mechanism of this change is that aforementioned deformation leads to a multiple rupture of electronic bonds and an increase in the electron concentration in the dislocation core to approximately value 1018 cm–3. The developed analytical model of the degradation mechanism allows to perform selection of a semiconductor and estimation of a laser operating mode under conditions of increased radiation power.
Understanding Well Interference and Parent-Child Well Relationships With Liquid Molecular Chemical Tracer Technology
Authors: Banerjee Sudiptya 
Published: August 2020

In an era where capital markets are hitting the brakes on funding the US shale sector, operators have increasingly pivoted from production growth to maximizing the rates of return via lower-cost wells. One of the major challenges of this new era is the determination of optimal stage and well spacing for a drilling area. For much of the US, the trend has been toward increased job size and rapid downspacing of infill or “child” wells. The unintended consequence of this trend has been an increase in fracture interference and excessive cross-well communication, which results in an overcapitalization of acreage and underperforming child wells as the drainage areas of wells overlap and compete for depleted resources. Within the SCOOP/STACK play, child wells completed in 2017/2018 have been half as productive as their 2015/2016 parent wells, a trend theorized to be directly related to negative fracture interactions.
Determining an optimal spacing between parent and infill wells is not a straightforward endeavor. An ideal development strategy is not just about well spacing, as decisions in completion design can exacerbate issues stemming from tight spacing. For this multivariate problem, operators have attempted to use bottomhole pressure measurements to extrapolate fracture interference or to use large data sets in a “trial-and-error” approach to understand well interference behavior. These approaches have significant downsides, relying either on data sets of questionable value or on extrapolating data to and from wells with significantly different geological conditions.
One operator in the SCOOP/STACK has attempted to understand well interference with chemical tracer technology. Using liquid molecular tracers, this operator achieved a quantified understanding of flow between parent/child wells with a high degree of confidence. This inexpensive technology has allowed the operator to experiment with well spacing and repressurization of parent wells. This, in turn, permits the rapid evaluation of mitigation techniques to optimize its field development strategy based on an accurate measurement of interwell fluid movement.
Tracer Selection
Two categories of chemical tracer are commonly used in conjunction with hydraulic fracturing operations: infused solid particulate tracers and liquid molecular tracers. While both tracer products have their strengths and weaknesses, liquid molecular tracers were chosen as a best practice in this study as they allow for quantification of the traced fluid phase, unlike infused solid particulate tracers.

Abstract
Background: To examine differences in the maternal characteristics and pregnancy outcomes of Chinese women with various causes of infertility who underwent in vitro fertilization (IVF) with embryonic cryopreservation treatment.Methods: Cases were pregnancies after IVF-ET with embryonic cryopreservation; controls were spontaneously conceived pregnancies. Subgroup analysis was carried out according to etiology of infertility. The IVF treatment group was divided into 5 subgroups according to infertility etiology as follows: ovulation disorder, tubal disease, male infertility, endometriosis, and mixed infertility. Data on demographic characteristics, medical history, laboratory tests, and delivery were reviewed. Logistic regression analysis was performed for pregnancy and perinatal complications and neonatal outcomes. The multivariable model was adjusted for potential confounders.Results: Among singleton pregnancies, compared with spontaneous pregnancies, IVF pregnancies were associated with significant increases in the rates of the following: gestational diabetes mellitus (GDM) (aOR 1.76[95% CI 1.33-2.33]), preeclampsia (2.60[1.61-4.20]), preterm preeclampsia (4.52[2.03-10.06]), postpartum hemorrhage (1.57[1.04-2.36]), intrahepatic cholestasis of pregnancy (3.84[1.06-13.94]), preterm premature rupture of membranes (2.11[1.17-3.81]), preterm birth (1.95[CI 1.26-3.01]), low birthweight (1.90[1.13-3.20]), macrosomia (1.53[1.03-2.27]), and neonatal intensive care unit (NICU) admission (1.69[1.22-2.34]) in the ovulation disorder group; GDM (1.50[1.21-1.86]), placenta previa (2.70[1.59-4.59]), placenta accreta (1.78[1.10-2.89]), postpartum hemorrhage (1.61[1.19-2.18]), macrosomia (1.60[1.21-2.13]) and 5-minute Apgar score ≤7 (4.09[1.04-16.08]) in the tubal disease group; placenta previa (9.33[4.22-20.62]), small for gestational age (2.29[1.04-5.08]), macrosomia (2.00[1.02-3.95]) and NICU admission (2.35[1.35-4.09]) in the endometriosis group; placenta previa (4.14[2.23-7.68]) and placenta accreta (2.05[1.08-3.87]) in the male infertility group; and GDM (1.85[1.15-2.98]), placenta previa (4.73[1.83-12.21]), placental abruption (3.39[1.20-9.56]), chorioamnionitis (2.93[1.04-8.26]), preterm birth (2.69[1.41-5.15]), and 1-minute Apgar score ≤7 (4.68[1.62-13.51]) in the mixed infertility group. Among multiple pregnancies, most of the differences that were significant in singleton pregnancies were less extensive or had disappeared.Conclusions: Infertility etiology within the IVF population was found to affect maternal and neonatal outcomes among all births. During the perinatal period, infertility etiology appears to be an additional risk factor for abnormal pregnancy outcomes besides the use of IVF techniques compared with spontaneous pregnancies. Higher risk was found for ovulation disorders, and lower risk was found for male infertility.
