Objective: To analyze factors related to non-motor symptoms in patients with moderate severe Parkinson’s disease. Subjects and Methods: From March 2022 September 2023, 93 disease were enrolled a cross-sectional descriptive study at the Outpatient Department of Bach Mai Hospital. Results: Factors affecting cardiovascular symptoms: Advanced age (≥70 years) stage increased risk orthostatic hypotension (p < 0.05). sleep disorders (based on NMSS Epworth scores): years), duration ≥5 years,...
Binary code analysis has attracted much attention. The difficulty lies in constructing a Control Flow Graph (CFG), which is dynamically generated and modified, such as mutations. Typical examples are handling dynamic jump instructions, destinations may be directly modified by rewriting loaded instructions on memory. In this paper, we describe PhD project proposal hybrid approach that combines static testing to construct CFG from binary code. Our aim minimize false targets produced when...
TB infection (TBI) is diagnosed using the technique-dependent tuberculin skin test (TST) or costly, more accurate interferon-gamma release assays. The TST (⩾10 mm) threshold was indicated by previous research among household contacts in Vietnam, but routine implementation with a different reagent showed unexpectedly low positivity.TST (⩾5 mm and ⩾10 results were compared to QuantiFERON™-TB Gold Plus (QFT) during community campaigns 2020 2021.This cross-sectional multi-center study.Among...
A high-order finite-volume method with anisotropic adaptive mesh refinement (AMR) is combined a parallel inexact Newton integration scheme and described for the solution of compressible fluid flows governed by Euler Navier-Stokes equations on three-dimensional multi-block body-fitted hexahedral meshes.The proposed approach combines family robust accurate central essentially non-oscillatory (CENO) spatial discretization schemes scalable efficient Newton-Krylov-Schwarz (NKS) algorithm...
Transthoracic biopsy has proven to be an effective procedure, especially for peripheral lung lesions, in obtaining samples that can definitively diagnose the underlying pathology. Despite its effectiveness, studies have demonstrated it is associated with complications such as pneumothorax and hemoptysis. This study aims evaluate incidence of these identify prognostic factors patients who underwent a transthoracic biopsy.
Automatic face and facial feature detection by a computer is computationally challenging problem. There are many shape patterns for eyes, nose mouth, hair, beards/mustaches, the overall geometry of frame. The texture color hair skin also vary greatly. One source complexity in analyzing images due to different appearances resulting from orientations. From literature authors' own experience, it apparent that various orientations, eyeglasses, among main factors affecting image analysis...
Rice Color Sorter plays an important role in the postharvest rice processing assembly. The quality and price of export will be increased by using this machine for classifying finished-rice. This paper presents designing, slide–adjustment structure position nozzles a color sorter machine. Slides, materials-catching slide are main factors classifying-component Sorter. relative positions these decide accuracy response-ability identification process high speed CCD camera. Moreover, relationship...
Single Point Incremental Forming (SPIF) has become a popular technology of forming sheet materials in the recent decades. However, springback phenomenon, an inborn property almost all elasto-plastic materials, reduces precision dimensions products by finished session. This paper attempts to find out measure minimize this unwanted obstacle using both empirical and simulating methods order define relations values among parameters such as diameter tool, its revolution per minute, velocity feed...
Abstract Automatic classification of virus instances into a concept hierarchy has been attracting much attention from malware research community. However, it is definitely not trivial work, because malwares usually come in binary forms whose actions are complicated and obfuscated. Therefore, the typical data mining approaches based on feature extraction easily applied. In this paper, we tackle problem by introducing framework known as MarCHGen (Malware Concept Hierarchy Generation)....
This paper discusses a collection of image operators we originally developed for automatic analysis face images, but they can also be applied to many other domains. Most these are new operators, few enhanced variants: two region segmentation algorithms (edge-based and intensity-based), feature detectors (a hybrid morphological-Laplacian, an oriented morphological edge detector), thin detector by gradient with statistical thresholding, nonlinear smoothing filter (micro-clustering). These were...

The accord modular easy installation, repairand upgrades. includes:emitter module, detector adjustment mechanism, andmechanical frame. All modules were by CAD-CAM and machinedby CNC machines high accuracy In additionfor using mechanisms adjust modules.
The sulfur granulation roller (rotoformer) mechanism and cooling steel conveyor is important clusters in system. This paper presents method to design rotoformer, apply goal: create a continuous pressure for regular on conveyor. There are also that granulates maintains temperature so not stuck solidify the supplying pipes. Moreover, this shows solution cool conveyor, filter system has sensors which ensure decreasing of over length will help sulfur, formed right size shape.
A new adaptive weighted essentially non-oscillatory WENO-$\theta$ scheme in the context of finite difference is proposed. Depending on smoothness large stencil used reconstruction numerical flux, a parameter $\theta$ set adaptively to switch between 5th-order upwind and 6th-order central discretization. indicator $\tau^{\theta}$ measuring chosen among two candidates which are devised based possible highest-order variations polynomials $L^2$ sense.
