A novel approach for recognizing human activities with wearable sensors is investigated in this article. The key techniques of this approach include the generalized discriminant analysis (GDA) and the relevance vector machines (RVM). The feature vectors extracted from the measured signal are processed by GDA, with its dimension remarkably reduced from 350 to 12 while fully maintaining the most ...

This study proposes an investigation of a novel thermal image enhancement based on bi-dimensional empirical mode decomposition (BEMD) and applies this method for rotating machinery fault diagnosis system. In this work, thermal images of machine conditions are firstly decomposed into intrinsic mode functions (IMFs) by utilizing BEMD. At each decomposition level, the IMF is expanded and fused wit...

In this paper, a varactor with metal–semiconductor–metal diodes on top of the (NH 4) 2 S/P 2 S 5-treated AlGaN/GaN two-dimensional electron gas epitaxial structure (MSM-2DEG) is proposed to the surge protection for the first time. The sulfur-treated MSM-2DEG varactor properties, including current–voltage (I–V), capacitance–voltage (C–V), and frequency response of the proposed surge protection c...

Triazoles are the mainstay of treatment for aspergillosis, although resistance to these antifungal agents may be associated with treatment failure. Refractory infections often necessitate a switch to other antifungal agents, including amphotericin B (AmB), although these infections may not resolve. The aim of this study was to investigate the effect of prior azole exposure on AmB sensitivity in...

In addition to dopaminergic neuron loss, it is clear that Parkinson disease includes other pathological changes, including loss of additional neuronal populations. As a means of addressing multiple pathological changes with a single therapeutically-relevant approach, we employed delayed transplantation of a unique class of astrocytes, GDAs(BMP), that are generated in vitro by directed different...

We estimate kinematical higher-twist (up to twist 4) corrections the ${\ensuremath{\gamma}}^{*}({q}_{1})\ensuremath{\gamma}({q}_{2})\ensuremath{\rightarrow}M({p}_{1})\overline{M}({p}_{2})$ amplitudes at large ${Q}^{2}=\ensuremath{-}{q}_{1}^{2}$ and small $s=({q}_{1}+{q}_{2}{)}^{2}$, where $M$ is a scalar or pseudoscalar meson. This process known factorize leading into perturbatively calculable ...

Harmful algal blooms (HABs), varying in intensity and causative species, have historically occurred throughout the Chesapeake Bay, U.S.; however, phycotoxin data are sparse. The spatiotemporal distribution of phycotoxins was investigated using solid-phase adsorption toxin tracking (SPATT) across 12 shallow, nearshore sites within lower Bay Virginia's coastal bays over one year (2017-2018). Eigh...

Emerging evidence suggests significant influence of comorbid anxiety on COPD. Several studies have reported a high prevalence of anxiety in COPD, but the rates vary widely. Review articles have reported the prevalence of GAD is 10% 15.8% in COPD patients compared to 3.6% 5.1% in the general public. We aim to study the prevalence of GAD in COPD patients and general population. Patients of COPD w...
