BACKGROUND DATA AND OBJECTIVE There is anecdotal evidence that low-level laser therapy (LLLT) may affect the development of muscular fatigue, minor muscle damage, and recovery after heavy exercises. Although manufacturers claim that cluster probes (LEDT) maybe more effective than single-diode lasers in clinical settings, there is a lack of head-to-head comparisons in controlled trials. This stu...
Background and Aim: “Active ageing” is the process of optimizing opportunities for health, participation and security of the elderly in order to enhance their quality of life. This study aimed to measure the Active Ageing Index (AAI) in Tehran at the individual level and determine its determinants. Materials and Methods: This quantitative cross-sectional study included 590 old people 55 ye...
OBJECTIVE To identify serum ion patterns that distinguish remission from active disease in patients with Wegener's granulomatosis (WG). METHODS Using sera collected in the WG Etanercept Trial, we selected samples from patients who either were undergoing a period of extended disease remission or had recent flares of active WG. Unfractionated samples were randomized into sets for training and t...
In this manuscript, we present an energy-efficient alternating optimization framework based on the multi-antenna ambient backscatter communication (AmBSC) assisted cooperative non-orthogonal multiple access (NOMA) for next-generation (NG) internet-of-things (IoT) enabled networks. Specifically, energy-efficiency maximization is achieved considered AmBSC-enabled multi-cluster IoT NOMA system by ...
The efficient use of energy source in a sensor node is most desirable criteria for prolong the life time of wireless sensor network. In this paper, we propose a two layer hierarchical routing protocol called Cluster Based Hierarchical Routing Protocol (CBHRP). We introduce a new concept called head-set, consists of one active cluster head and some other associate cluster heads within a cluster....
TtcA catalyzes the post-transcriptional thiolation of cytosine 32 in some tRNAs. The enzyme from Escherichia coli was homologously overexpressed in E. coli. The purified enzyme is a dimer containing an iron-sulfur cluster and displays activity in in vitro assays. The type and properties of the cluster were investigated using a combination of UV-visible absorption, EPR and Mössbauer spectroscopy...
Clustering in Mobile Ad Hoc Networks (MANETs) has much better utilization compared to the conventional system. Other than the highly active and unbalanced nature of MANETs makes it hard for the cluster based routing protocols to split a mobile network into clusters and determination of cluster heads for each cluster. In this paper, we analyze and compare some of existing works on cluster based ...
Introduction and purpose: Aging population is increasing and it is of great importance to predict factors that promote physical and mental health status of elderly. This study aimed to predict the perceived rejection based on early maladaptive Schema among active and inactive elderly. Methods & Materials: We used cluster sampling method to collect 150 elderly (included 75 active and 75 inact...
Chemometric method such as cluster and principal component analyses applied for alkanes C6-C10 detection in the air. To increase piezosensor selectivity to analytes L-apiezon is applied as active modifier. It is shown that processing of piezosensor signals to analytes with cluster and principal component analyses allows to refer (to identify) substance to the appropriate alkane (hexane, heptane...
A novel aminoacyl-tRNA synthetase that contains an iron-sulfur cluster in the tRNA anticodon-binding region and efficiently charges tRNA with tryptophan has been found in Thermotoga maritima. The crystal structure of TmTrpRS (tryptophanyl-tRNA synthetase; TrpRS; EC 6.1.1.2) reveals an iron-sulfur [4Fe-4S] cluster bound to the tRNA anticodon-binding (TAB) domain and an L-tryptophan ligand in the...
