Interstellar scintillation(ISS)is a well-known phenomenon observed from pulsars in the Milky *** comprises intensity variations *** and frequency caused by constructive and destructive interference from multipath propagation,which is due to diffraction from fluctuations in electron density in the interstellar medium(ISM)on scales as small as~100 *** density fluctuations appear to be part of a turbulence process combined with discrete structures in electron density from other astrophysical processes;together these fluctuations extend to scales of pc or larger.

Edge computing, which migrates compute-intensive tasks to run on the storage resources of edge devices, efficiently reduces data transmission loss and protects data privacy. However, due to limited computing resources and storage capacity, edge devices fail to support real-time streaming data query and processing. To address this challenge, first, we propose a Long Short-Term Memory (LSTM) network-based adaptive approach in the intelligent end-edge-cloud system. Specifically, we maximize the Quality of Experience (QoE) of users by automatically adapting their resource requirements to the storage capacity of edge devices through an event mechanism. Second, to reduce the uncertainty and non-complete adaption of the edge device towards the user’s requirements, we use the LSTM network to analyze the storage capacity of the edge device in real time. Finally, the storage features of the edge devices are aggregated to the cloud to re-evaluate the comprehensive capability of the edge devices and ensure the fast response of the user devices during the dynamic adaptation matching process. A series of experimental results show that the proposed approach has superior performance compared with traditional centralized and matrix decomposition based approaches.

Background:The focus of triticale breeding in the southern Great Plains of the United States has been to increase forage yield for autumn-winter seasons when most other forage species are *** study aims to estimate the trends of seasonal yield changes over ***:Yield trials had been conducted in a randomized complete block design for up to two *** yield changes over time were estimated using linear regression ***:The analysis revealed a significant positive relation between autumn forage yield(relative to common checks)and calendar years when the trials were *** estimated improvement of autumn forage yield was about 1.9%per year on medium and heavy soil at Ardmore,Oklahoma,and about 5.4%per year on light soil at Burneyville,***,winter forage yield change was minimal and the spring forage yield increase was negative,although this decline was not *** forage yield improvements were about 0.6%and 0.7%per year at Ardmore and Burneyville,*** results were also observed when years of cultivars'introduction were used ***:The results indicate a significant gain in autumn forage yield,but a minor gain in the total forage yield due to the yield tradeoff between the autumn and spring seasons.

Background and Objective: Non-invasive body contouring treatments is one of the fastest growing markets in the aesthetic field. The main purpose of radiofrequency (RF)-based devices for body contouring is to produce thermal stimulus which leads to skin tightening effect by dermal collagen production and decreases the volume of adipose tissue by a reduction of the adipocyte’s cytosolic. The cutaneous application of RF devices in Asian patients differs in several respects from their use in Caucasians;therefore the objective of this study was to evaluate the safety and efficacy of a novel RF device used for focal fat reduction. Materials and Methods: Twenty-two Asian patients aged 24 - 51, Fitzpatrick skin types III-V, were enrolled to the study and received 6 sessions of consecutive abdomen contouring treatment with bi-polar RF device combined with a mechanical pressure. Statistical linear correlation tests and descriptive analysis were performed on the cohort. Results: All twenty-two patients treated for six treatments showed some degree of circumferential reduction with a stable weight. No adverse events were recorded during the whole period of trial. During the 3-month follow up visit, no deterioration of the body condition was detected. No statistical significant relation was found between circumference change and weight, age, height?or BMI. Conclusions: The majority of the patients exhibited a substantial circumferential reduction, not at the expense of weight loss. The bi-polar RF device was found to be safe for Asian skin.

Lighting is crucial for portrait photography,yet the complex interactions between the skin and incident light are expensive to model computationally in graphics and difficult to reconstruct analytically via computer ***,to allow fast and controllable reflectance and lighting editing,we developed a physically based decomposition through deep learned priors from path-traced portrait *** approaches that used simplified material models or low-frequency or low-dynamic-range lighting struggled to model specular reflections or relight directly without intermediate ***,we estimate the surface normal,skin albedo and roughness,and high-frequency HDRI maps,and propose an architecture to estimate both diffuse and specular reflectance *** our experiments,we show that this approach can represent the true appearance function more effectively than simpler baseline methods,leading to better generalization and higher-quality editing.

This paper investigates the design problem of a sliding mode controller for linear repetitive processes(LRPs) with a finite pass length on each pass. Under limited communication resources, an eventtriggered mechanism is implemented from the sensors to the controller, whose triggered sequence is consistent with the evolution direction of LRPs. To periodically orchestrate communication between the controller and actuator, a round-robin scheduling mechanism is established based on the pass length. A sliding function involving the state and pass profile is constructed, and the sliding mode controller is designed using triggered states and pass profile signals. Feasible controller gains are attained to ensure the stability of the resultant closed-loop system. Finally, the proposed strategy is implemented for a multi-roll metal rolling process.
