—In this research, a compact printed antenna design operating on ultra-wideband (UWB) and three extra wireless communication bands is proposed. An ellipse-shaped monopole is utilized to realize UWB application (3.1–10.6 GHz). The modified ground employs three folded Capacitive Loaded Line Resonators (CLLRs) to obtain triple relatively lower communication(More)
BACKGROUND Selective tibial neurotomy (STN) was considered as an effective procedure for the treatment of spastic feet. It's also widely used for treating obese calves in some Asian countries currently. This study aimed to provide morphological measurement data and theoretical support for the operation and intraoperative localization. METHODS Fifty lower(More)
The aim of this study was to report a rare case of Aspergillus fumigatus infection complicated with cav-ernous hemangioma in the central nervous system of a patient with normal immune function and to investigate its causes. A 60-year-old male patient was admitted three years ago due to meningioma-induced convulsions. In addition to meningioma, magnetic(More)
Animal and clinical studies have confirmed the therapeutic effect of bone marrow mesenchymal stem cells on cerebral ischemia, but their mechanisms of action remain poorly understood. Here, we summarize the transplantation approaches, directional migration, differentiation, replacement, neural circuit reconstruction, angiogenesis, neurotrophic factor(More)
OBJECTIVE A potential association between diabetes and Guillain-Barré syndrome (GBS) has been indicated by a few case studies. We retrospectively analyzed the clinical features of a large cohort of GBS patients to explore the relationship between the level of fasting plasma glucose (FPG) obtained in the acute phase at admission and the severity of GBS.

An improved adaptive filtering (IMPNLMS+) algorithm has been proposed for non-sparse impulse responses by incorporating an adaptive parameter μ of the μ-law compression into the improved μ-law PNLMS algorithm (IMPNLMS) algorithm. It not only achieves optimal step-size control factors but also overcomes that the convergence of classical μ-law PNLMS (MPNLMS)(More)
