Both 10-mm-thick sections 1.5- or 3.0-mm-thick HRCT scans were obtained. Distribution classified as centrilobular, panlobular, perilobular, bronchovascular, nonlobular. Intralobular classification distribution more feasible less severely diseased regions. revealed thickened...

For a multi-cell, multi-user, cellular network downlink sum-rate maximization through power allocation is nonconvex and NP-hard optimization problem. In this article, we present an effective approach to solving problem single- multi-agent actor-critic deep reinforcement learning (DRL). Specifically, use finite-horizon trust region optimization. Through extensive simulations, show that can simultaneously achieve higher spectral efficiency than state-of-the-art algorithms like weighted minimum...

Optimizing the sum-log-utility for downlink of multi-frequency band, multiuser, multiantenna networks requires joint solutions to associated beamforming and user scheduling problems through use cloud radio access network (CRAN) architecture; optimizing such a is, however, non-convex NP-hard. In this paper, we present novel iterative strategy based on fractional programming Hungarian algorithm. The allows us iteratively maximize chosen objective function in fashion similar block coordinate...

Coronavirus disease 2019 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which known to be associated with immune dysregulation and can cause multiorgan dysfunction. Sarcoidosis another increased inflammatory responses due also affect multiple organs. Although sarcoidosis, like COVID-19 infection, virtually any organ, the lungs are most commonly affected presents as lung nodules bilateral hilar lymphadenopathy. Rarely, granulomatous...

A base-station (BS) equipped with multiple antennas can use its spatial dimensions in three different ways: (1) to serve users, thereby achieving a multiplexing gain, (2) provide diversity order improve user rates and (3) null interference neighboring cells.This paper answers the following question: What is optimal balance between these competing benefits?We answer this question context of downlink cellular network, where multi-antenna BSs single-antenna users using zero-forcing beamforming...

The problem of optimizing scheduling and beamforming to maximize the network weighted sum rate (WSR) for downlink multicell, multi-antenna networks is challenging due its nonconvexity NP-hardness.

Part I of this two-part paper focused on the formulation percentile problems, complexity analysis, and development power control algorithms via quadratic fractional transform (QFT) logarithmic (LFT) for sum-least-qth-percentile (SLqP) rate maximization problems. In second part, we first tackle significantly more challenging problems optimizing SLqP beamforming in a multiuser, multiple-input multiple-output (MU- MIMO) network to maximize cell-edge throughput. To end, propose an adaptation QFT...

Improving throughput for cell-edge users through coordinated resource allocation has been a long-standing driver of research in wireless cellular networks. While variety management problems focus on sum utility, max-min utility and proportional fair these formulations do not explicitly cater to can, fact, be disadvantageous them. In this two-part paper series, we introduce new class optimization called percentile programs, which allow us formulate that target lower-percentile users. Part I...

Vibrations in rotating machinery are commonly the result of mechanical faults including mass unbalance, coupling misalignment, looseness etc. Rotating with overhung rotors is very common industries. Unbalanced rotor and misaligned shafts usually cause excessive machine vibration, generates large forces on bearings thus reduces life span may lead to property loss even human life. Two-plane balancing one most challenging problem that maintenance engineers encounter. As a prerequisite,...

Misalignment is considered as the second most prevalent vibration source after unbalance.A misaligned rotor always causes more and generates excessive force in bearing area which reduces life of machine.Couplings are widely used because their ability to transmit torque from driving driven shaft consequent compensate misalignment.This work addresses problem condition monitoring mechanical faults due misalignment.We studied observed signatures two different coupling types affect increased...

INTRODUCTION: Hepatic encephalopathy (HE) is a clinical diagnosis and rarely requires neuroimaging. the most common for patients with cirrhotic presenting altered mental status (AMS). It diagnosis, computed tomography (CT) of brain does not contribute to diagnostic or grading information. However, cirrhosis are at increased risk intracerebral hemorrhage, therefore, CT scans usually performed rule out other etiologies AMS, which may lead overutilization scans. There limited data on magnitude...

Optimizing the downlink of multi-cell multiuser multiple input output (MU-MIMO) networks has received substantial attention; however, schemes in literature consider centralized solutions requiring significant overhead information exchange (e.g., global channel state or CSI) and computation load (the need to solve a single large problem).
