A regression-based model evaluation of the Curie temperature of transition-metal rare-earth compounds

The Curie temperature (TC) of RT binary compounds consisting of 3d transition-metal (T ) and 4f rare-earth elements (R) is analyzed systematically by a developed machine learning technique called kernel regression-based model evaluation. Twenty-one descriptive variables were designed assuming completely obtained information of the TC. Multiple kernel regression analyses with different kernel types: cosine, linear, Gaussian, polynomial, and Laplacian kernels were implemented and examined. All possible descriptive variable combinations were generated to construct the corresponding prediction models. As a result, by appropriate combinations between descriptive variable sets and kernel formulations, we demonstrate that a number of kernel regression models can accurately reproduce the TC of the RT compounds. The relevance of descriptive variables for predicting TC are systematically investigated. The results indicate that the rare-earth concentration is the most relevant variable in the TC phenomenon. We demonstrate that the regression-based model selection technique can be applied to learn the relationship between the descriptive variables and the actuation mechanism of the corresponding physical phenomenon, i.e., TC in the present case.
A new approach for oil tank detection using deep learning features with control false alarm rate in high-resolution satellite imagery

ABSTRACT Oil tank detection is a challenging task, primarily due to high time-consumption. This paper aims at further investigating this challenge and proposes a new hierarchical approach to detect oil tanks, especially with respect to how false alarm rates are reduced. The proposed approach is divided into four stages: region of interest (ROI) extraction, circular object detection, feature extraction, and classification. The first stage, which is a key component of this approach to reduce false alarm and processing time, is applied by an improved faster region-based convolutional neural network (Faster R-CNN) to extract oil depots. In the second stage, a number of candidate objects of the target are selected from the extracted ROIs by a fast circle detection method. Afterwards, in the third stage, a robust feature extractor based on a combination of the output feature vectors from convolutional neural network (CNN), as a high-level feature extractor, and histogram of oriented gradients (HOG), as a low-level feature extractor, are used for representing features of various targets. Finally, the support vector machine (SVM) is employed for classification. The experimental results confirm that the proposed approach has good prediction accuracy and is able to reduce the false alarm rates.

Comparison of Near‐Surface NO2 Pollution With Pandora Total Column NO2 During the Korea‐United States Ocean Color (KORUS OC) Campaign

Near‐surface air quality (AQ) observations over coastal waters are scarce, a situation that limits our capacity to monitor pollution events at land‐water interfaces. Satellite measurements of total column (TC) nitrogen dioxide (NO2) observations are a useful proxy for combustion sources, but the once daily snapshots available from most sensors are insufficient for tracking the diurnal evolution and transport of pollution. Ground‐based remote sensors like the Pandora Spectrometer Instrument (PSI) that have been developed to verify space‐based TC NO2 and other trace gases are being tested for routine use as certified AQ monitors. The KORUS‐OC (Korea‐United States Ocean Color) cruise aboard the R/V Onnuri in May–June 2016 represented an opportunity to study AQ near the South Korean coast, a region affected by both local/regional and long‐distance pollution sources. Using PSI data in direct‐Sun mode and in situ sensors for shipboard ozone, CO, and NO2, we explore, for the first time, relationships between TC NO2 and surface AQ in this coastal region. Three case studies illustrate the value of the PSI and complexities in the surface‐column NO2 relationship caused by varying meteorological conditions. Case Study 1 (25–26 May 2016) exhibited a high correlation of surface NO2 to TC NO2 measured by both PSI and Aura's Ozone Monitoring Instrument, but two other cases displayed poor relationships between in situ and TC NO2 due to decoupling of pollution layers from the surface. With suitable interpretation the PSI TC NO2 measurement demonstrates good potential for working with upcoming geostationary satellites to advance diurnal tracking of pollution.

Objective To observe the expression of CyclinE in esophagus squamous carcinoma and the normal esophagus tissue and to clarify its significance in esophagus carcinogenesis.Methods CyclinE protein expression was detected by immunohistochemistry(MaxVision method) using the monoclonal antibody and its intensity was assessed quantitative by image-pro plus image analysis system.Results The monoclonal antibody showed specific cell nucleus.CyclinE positive unit(PU) were significantly larger in the esophagus squamous carcinoma than that in normal esophagus tissue(P0.001). CyclinE PU of the nuclei were significantly larger in the poorly-differentiated esophagus squamous carcinoma than those in the highly-differentiated esophagus squamous carcinoma and the moderately-differentiated esophagus squamous carcinoma(P0.001). CyclinE PU was not involved in the patient's sex,age,tumor'metastasis and staging(P0.05). Conclusion CyclinE protein expression was involved in the esophagus carcinogenesis and its differentiation and might be helpful for distinguishing carcinoma from normal tissues and ascertaining the histological grading.
A crustal profile of the heat production of the Harts Range Group, Northern Territory

Summary Medium pressure-high temperature (MP-HT) metamorphism is generally accepted to be driven by crustal thickening within compressional tectonic regimes. Despite this consensus, the Harts Range Group located in central Australia provides evidence for MP-HT metamorphism occurring as a result of burial in a deep intracontinental rift. Detrital zircon studies of metasediments within the Harts Range and surrounding sedimentary sequences indicate that the Harts Range Group represent the metamorphosed equivalents of the sedimentary successions located in the neighbouring Late Neoproterozoic to Cambrian Amadeus and Georgina Basins. Whilst the metamorphic character of this region has been studied, the thermal character of each of the individual sequences that infilled the rift are yet to be examined. The exhumation and preservation of all metamorphosed components of the Harts Range rift basin, along with the proximity of these metasediments to their protolith equivalents, provide a unique opportunity to examine the heat production of components that infilled the rift throughout the Cambrian. We undertake a field study to measure heat production across three lithological units that comprise the Harts Range Group. We also apply heat production calculations to calibrated airborne radiometric datasets in order to calculate the approximate heat production of these sedimentary sequences when buried to ~30 km depth. We use the ground-sourced measurements as a tool to validate our derivation of heat production from airborne radiometrics. If statistically sound, we are then able to use the airborne radiometric dataset to calculate average heat production and relative heat flow of each succession contained within the rift. This can provide insights into the thermal drivers of medium pressure-high temperature metamorphism in an extensional intracratonic tectonic setting.
Mesoscale and Submesoscale Contributions to High Sea Surface Chlorophyll in Subtropical Gyres

Mesoscale eddies in the oceans are known to modify the nutrient supply, stimulate phytoplankton growth, and significantly affect carbon fixation. Submesoscale processes associated with mesoscale eddies have been suggested to induce even stronger variability in phytoplankton dynamics; however, their large‐scale impact has not been quantitatively evaluated in the global ocean. By combining multiple satellite products to resolve both mesoscale and submesoscale dynamic regimes, we evaluated their contributions to high sea surface chlorophyll. Our results reveal that the dominant dynamics associated with high chlorophyll in different gyres are not the same and can vary from the mesoscale to the submesoscale. In subtropical gyres worldwide, the contribution of submesoscale structures around mesoscale eddies to high chlorophyll is comparable to that of mesoscale eddies (34.1% versus 30.8%). These results extend our current understanding of the impacts of eddies on biogeochemical processes and may have important implications for the global carbon cycle.
Expression of MMP-2 in cholangiocarcinoma and its correlation with prognosis

AIM:To investigate the clinicopathological features of the expression of matrix metalloproteinase-2(MMP-2)in cholangiocarcinoma(CCA),and to evaluate its clinical significance in the histologic classification and prognosis of patients with CCA.METHODS:106 patients with CCA were examined for MMP-2 expression by SP immunohistochemistry.Then,the clinical outcome of the patients after a median follow-up of 1-60 months was determined in 89 out of the 106 patients.RESULTS:The positive rates of MMP-2 in CCA were 76.42%(81/106). Clinicopathological parameters of CCA and clinical outcome of the patients were associated with MMP-2 expression.MMP-2 was expressed more frequently in CCA tissues with tumor invasion,poor differentiation and lymph node metastasis.Moreover,the survival rate of the patients with CCA expressing MMP-2 was significantly lower than that of the patients without MMP-2 expression(P0.01). CONCLUSION:MMP-2 expression in cancerous tissues may play an important role in invasion and metastasis of CCA.The detection of it along with clinical staging may help to predict patients' prognosis.
Multisensor validation of tidewater glacier flow fields derived from synthetic aperture radar (SAR) intensity tracking

Abstract. Following the general warming trend in Greenland, an increase in calving rates, retreat and ice flow has been observed at ocean-terminating outlet glaciers. These changes contribute substantially to the current mass loss of the Greenland Ice Sheet. In order to constrain models of ice dynamics as well as estimates of mass change, detailed knowledge of geometry and ice flow is needed, in particular on the rapidly changing tongues of ocean-terminating outlet glaciers. In this study, we validate velocity estimates and spatial patterns close to the calving terminus of such an outlet derived from an iterative offset-tracking method based on synthetic aperture radar (SAR) intensity data with a collection of three independent reference measurements of glacier flow. These reference datasets are comprised of measurements from differential GPS, a terrestrial radar interferometer (TRI) and repeated unmanned aerial vehicle (UAV) surveys. Our approach to SAR velocity processing aims at achieving a relatively fine grid spacing and a high temporal resolution in order to best resolve the steep velocity gradients in the terminus area and aims to exploit the 12 d repeat interval of the single-satellite Sentinel-1A sensor. Results from images of the medium-sized ocean-terminating outlet glacier Eqip Sermia acquired by Sentinel-1A and RADARSAT-2 exhibit a mean difference of 11.5 % when compared to the corresponding GPS measurements. An areal comparison of our SAR velocity fields with independently generated velocity maps from TRI and UAV surveys showed good agreement in magnitude and spatial patterns, with mean differences smaller than 0.7 m d−1. In comparison with existing operational velocity products, our SAR-derived velocities show an improved spatial velocity pattern near the margins and calving front. There 8 % to 30 % higher surface ice velocities are produced, which has implications on ice fluxes and on mass budget estimates of similarly sized outlet glaciers. Further, we show that offset tracking from SAR intensity data at relatively low spatio-temporal sampling intervals is a valid method to derive glacier flow fields for fast-flowing glacier termini of outlet glaciers and, given the repeat period of 12 d of the Sentinel-1A sensor (6 d with Sentinel-1B), has the potential to be applied operationally in a quasi-continuous mode.
Film-Nanostructure-Controlled Inerasable-to-Erasable Switching Transition in ZnO-Based Transparent Memristor Devices: Sputtering-Pressure Dependency

We found that the write-once-read-many-times (WORM, inerasable)-to-rewritable (erasable) transition phenomenon results from the different structures of the filament, which is determined by the grain orientations of the deposited films. The conduction mechanism of this switching transition and its impact on the synaptic behavior in various ZnO nanostructures are also discussed. Furthermore, our WORM devices have a programmable physical damage function that can be exploited for use in security systems against data theft, hacking, and unauthorized use of software/hardware. This work proposes ZnO-based nonvolatile memory for invisible electronic applications and gives valuable insight into the design of WORM and rewritable memories.
7.2-kV/60-A Austin SuperMOS: An Intelligent Medium-Voltage SiC Power Switch

In order to enable medium-voltage applications at an operation voltage of 5-kV level, a novel 7.2-kV/60-A Austin SuperMOS SiC power switch is developed. Static and dynamic performances are characterized at various voltage and current levels. The device exhibits excellent dynamic performance with a high dV/dt up to 122 V/ns during the turn-off. The output charge of the Austin SuperMOS is also measured to enable accurate dynamic loss estimation. A unique automatic gate turn-on mechanism is identified, which facilitates a substantial reduction of the third quadrant conduction loss during the deadtime in converter operations. A high-voltage isolated power supply with low coupling capacitance and an optically triggered intelligent gate driver circuit with protection functions are integrated into the medium-voltage power switch, enabling safe and reliable medium-voltage operations of the Austin SuperMOS.
Macrólidos en fibrosis quística: Pasado, presente y futuro

Introduccion: La fibrosis quistica (FQ) es una condicion inflamatoria preferentemente neutrofilica que compromete el sistema respiratorio. Algunos autores han sugerido un beneficio discreto del uso de macrolidos como drogas anti-inflamatorias en determinadas circunstancias. Objetivo: Revisar los trabajos publicados en torno al uso de macrolidos en pacientes con FQ. Material y Metodos: Se realizo una busqueda bibliografica considerando ensayos clinicos originales indexados en el National Library of Medicine (MEDLINE/Pubmed) empleando las palabras: macrolides, azithromycin, immunomodulating, antiinflammatory, airway, cystic fibrosis and children. Resultados: Se identificaron seis ensayos clinicos que evaluaron los efectos de la azitromicina en ninos y adultos con FQ. Tres de los ensayos incluyeron placebo, pero solo dos incluyeron menores de 18 anos. El antecedente de colonizacion cronica con P. aeruginosa no fue un criterio de seleccion exclusivo. En todos se observo algun beneficio tanto en VEF1 como CVF. Luego de descontinuar la azitromicina, los niveles de funcion pulmonar retornaron a su nivel basal. En general, la tolerancia fue adecuada sin claras diferencias con el placebo. Conclusiones: Existe un claro pero modesto beneficio del uso de azitromicina en ninos con FQ, especialmente estando colonizados por P. aeruginosa; aunque esta casi libre de efectos adversos, aun faltan estudios que determinen sus efectos a largo plazo.
Design of an aquaponic system run on solar power for a family business in Chad

This article describes the design of a single-family aquaponic system powered by solar energy. This technique called “aquaponics” is an activity that blends aquaculture (farming aquatic species) and hydroponics (growing plants in a water-based environment) into one integrated system. A description is given of the elements in the aquaponic circuit, which is sized to scale for a family business, in addition to the budget required for its implementation in Chad. The use of renewable energy offers the possibility of implementing sustainable farming in underdeveloped countries. The objective of this system is to maximize the production of fish and vegetables, taking into account their limitations (20 kg of fish can be produced for every 1,000 liters of water while 8 liters of water are necessary to grow each plant). The fish farmed in this case will be tilapia, as it is technically feasible and has a flavor that is acceptable to the inhabitants of Chad. The cultivated plants include all types of fruits and vegetables, as well as aromatic plants.
Somatosensory evoked potentials and dynamic postural assessment in adolescent idiopathic scoliosis

Background Dysfunction of the somatosensory pathways may cause an impaired postural balance when the somatosensory system is challenged, and this impaired balance may play a role in the etiology or development of scoliosis. Angle of scoliosis may affect the somatosensory evoked potentials (SSEPs) and dynamic balance control. Purpose The aim of this study was to investigate possible abnormalities and correlations in SSEPs and dynamic posturography in adolescent idiopathic scoliosis (AIS) patients. Patients and methods This study was conducted on 14 adolescents ranging in age from 10 to 16 years with AIS. Both sexes were included. Measurement of Cobb′s angle, SSEPs of both posterior tibial nerves with cortical recording, dynamic postural assessment including sensory organization test, and motor control test were performed. Results There was a highly significant positive correlation between the angle of scoliosis and right and left SSEP. There was a highly significant negative correlation between the angle of scoliosis and equilibrium score-composite and ratio for sensory analysis-vestibular, and significant negative correlation with motor control-composite. There was a highly significant negative correlation between right SSEP and balance parameters. There was significant negative correlation between left SSEP and equilibrium score-composite and ratio for sensory analysis-vestibular. Conclusion The study demonstrates abnormal somatosensory and postural function in patients with AIS, and a significant inter-relationship between the scoliotic angle, the somatosensory system, and posture. Thus, optimum assessment and treatment of neurological pathway and balance are important in these patients.
Parasite Assemblages from Feline Coprolites through the Pleistocene-Holocene Transition in Patagonia: Cueva Huenul 1 Archaeological Site (Argentina)

ABSTRACT The aims of the present study were: (1) to examine the parasite fauna found in carnivore coprolites from Cueva Huenul 1 archaeological site, located in northern Patagonia (Neuquén Province, Argentina), (2) to evaluate the role of this carnivores in the cycle of zoonotic parasites in the past, (3) to discuss the possible effect of the infections in humans that inhabit the cave during the Quaternary, and (4) to evaluate possible differences in egg measurements among layers. Several coprolites were obtained from layers dated since the Pleistocene-Holocene Transition. Faeces were whole processed, rehydrated, homogenised, and examined via light microscopy. Eggs of parasites were measured and photographed. Coprolites were assigned to a small feline. A total of 11 parasite species were found (8 nematode, 2 trematode, and 1 coccidian species). The paleoparasitological findings of this study display a great richness of parasitic species present in felines from CH1 through the Pleistocene-Holocene transition, some of them zoonotic. Early human societies that discontinuously occupied the site during the time scale studied could have been exposed to these infections.
Delayed Weakening and Reactivation of Rate‐and‐State Faults Driven by Pressure Changes Due to Fluid Injection

Fault reactivation induced by pore pressure changes involves complex frictional phenomena because effective normal stresses vary in space and time due to fluid flow and rock deformation. The impact of time‐varying normal stresses on fault friction has been characterized in stress‐step laboratory experiments and modeled through extended rate‐and‐state laws that incorporate a stressing‐rate dependence of the state variable. Building on these rate‐and‐state models, we use 2‐D poroelastic simulations to understand how the evolution of pore pressures due to fluid injection affects fault strength and reactivation. A sharp increase in pore pressure, associated with fluid injection, leads to an increase in friction coefficient and to a delayed weakening of the fault. Conversely, a sharp pressure decrease during extraction leads to a delayed strengthening. Stressing‐rate effects emerge as a purely frictional mechanism that delays or accelerates the onset of fault slip, suggesting that reactivation under fluid injection may occur long after flow rates have decreased and pore pressures have stabilized at the fault. Hence, earthquakes induced by injection may ensue as a deferred process triggered several days later than predicted by simple estimates based on constant friction. The duration of the delay depends on the type of rate‐and‐state law used in calculations and on a characteristic relaxation time: The memory time over which the state variable evolves under stationary contact. Our results help understand the connection between injection protocols and frictional weakening mechanisms, suggesting that injection processes can be engineered to minimize the risk of induced seismicity for a given injected volume.
The Effect Of Short, Intermediate And Long Duration Of Swimming On Pulmonary Function Tests.

Background & Objectives: As muscular strength can be increased by regular exercise, it was decided to study the effect of strenuous swimming on the pulmonary function tests, as it involves both, the total body muscular activity and excessive use of chest and abdominal muscles following periods of breath holding, which is a part of training for competitive swimmers. Methods: Selected lung volumes and capacities were determined on 60 swimmers of three different groups i.e. group I- swimming experience of less than 2 years, Group II- between 2 to 5 years, and Group III- >5 years and compared with 60 controls. The purpose of the study is to find the effect of swimming for different duration on pulmonary function tests i.e. forced vital capacity (FVC), forced expiratory volume (FEV1), inspiratory Capacity (IC) And tidal Volume (TV) Result: Forced vital capacity (FVC), Forced expiratory volume (FEV1), Inspiratory Capacity (IC) And Tidal Volume (TV) of controls with swimmers of group II and III there is statistically significant and statistically highly significant increase in values were observed respectively. Conclusion: The swimming exercise for intermediate and long duration of time i.e. more than two (2) years produces a significant improvement in the pulmonary functions. This improvement is directly proportional to the
