Abstract Despite the known benefits of data‐driven approaches, lack approaches for identifying functional neuroimaging patterns that capture both individual variations and inter‐subject correspondence limits clinical utility rsfMRI its application to single‐subject analyses. Here, using data from over 100k individuals across private public datasets, we identify replicable multi‐spatial‐scale canonical intrinsic connectivity network (ICN) templates via use multi‐model‐order independent...
Magnetoelectric coupling and switching charge density in multiferroics have gained the attention of researchers around world for energy storage, harvesting, their potential applications pulsating devices. In multiferroics, absence inversion symmetry presence antiferromagnetic give rise to intriguing magnetoelectric coupling. this paper, bi-phase composites, (1–x)Bi0·9La0·1FeO3 + xSrCoO3 x = 0.1, 0.2, 0.3 are made by a facile time-saving sol–gel auto-combustion technique.

Compliant manipulators equipped with Variable Stiffness Actuation (VSA) possess the ability to safely interact their environment and adapt complex tasks. However, tracking performance of such is significantly influenced by intrinsic compliance varying stiffness. This paper presents a robust control strategy for compliant Discrete (DVSA), aimed at enhancing under both fixed stiffness conditions. By compensating nonlinear dynamics, joint coupling, frictions, variability uncertainties through...
Abstract LW a , ab b and LWEM are the four main antigens of Landsteiner–Weiner (LW) blood group system. expression may be weakened during pregnancy immune dysregulation, with subsequent appearance anti-LW. Here, we describe case an elderly male patient in whom transfusion red cells (RBCs) became challenging because presence A 61-year-old presented shortness breath hemoglobin level 7.0 g/dL, requiring RBC transfusions. Serologic workup his sample showed RBCs to A, D+, but serum was...
The detrimental effects of global warming and the reliance on hazardous energy sources such as coal petroleum have intensified pursuit clean sustainable alternatives. Among these,...
Rock strength, specifically the uniaxial compressive strength (UCS), is a critical parameter mostly used in effective and sustainable design of tunnels other engineering structures. This determined using direct indirect methods. The methods involve acquiring an NX core sample sophisticated laboratory procedures to determine UCS. However, are time-consuming, expensive, can yield uncertain results due presence any flaws or discontinuities sample. Therefore, most researchers prefer for...
Different methodologies for manipulators have been proposed and applied to robot obstacle detection avoidance in unstructured environments. These methods include different real-time sensors, observer-based algorithms, path planning using genetic algorithms. However, sensor design integration is complex considerably expensive. Moreover, the observer algorithm requires complete system dynamics information, which difficult derive. In this regard, algorithms are typically considered slow...
An electrocardiogram (ECG) signal may be affected by different types of disturbances/noises e.g. Power Line Interference (PLI), baseline wander, motion artifacts etc. Removing such disturbing signals from an ECG is the key to its accurate analysis leading diagnosis potential disease(s). In this paper, we present State Space Recursive Least Squares (SSRLS) filter based method for removal 50Hz PLI noise signal. The results are encouraging when compared with notch varying attenuation levels....
Abstract Minimizing total harmonic distortion (THD) with less system complexity and computation time is a stringent constraint for many power systems. The multilevel inverter can have low THD when switching angles are selected at the fundamental frequency. For low-order minimization, selective elimination (SHE) most adopted proficient technique but it involves non-linear transcendental equations which very difficult to solve analytically numerically. This paper proposes genetic algorithm...
