In this investigation, we consider wireless powered relaying systems, where energy is scavenged by a relay via radio frequency (RF) signals.We explore hybrid time switching-based and power splitting-based protocol (HTPSR) compare performance of Amplify-and-Forward (AF) with Decode-and-Forward (DF) scheme under imperfect channel state information (CSI).Most importantly, the instantaneous rate, achievable bit error rate (BER) are determined in closed-form expressions impact CSI.Through...
Niviventer is a genus of white-bellied rats that are among the most common rodents in Indo-Sundaic region. The taxonomy has undergone extensive revisions and remains controversial. current phylogeny unresolved was developed primarily on basis mitochondrial genes. Identification extremely difficult, large number GenBank sequences seem to be problematic. We extensively sampled specimens China neighboring northern Vietnam, including topotypes reported species (n = 6), subspecies 8), synonyms...
The Pt/C electrocatalysts containing Pr(6)O(11) nanorods were successfully prepared. By various electrochemical characterization methods, it was demonstrated that the have an obviously promotive role for ethanol electrooxidation catalyzed by Pt/C. However, according to stripping experiment, effect of does not result from easier intermediate adsorbate on Pt-Pr(6)O(11)/C than It supposed could promote a certain step in oxidation, and special morphology further enhance activity compared with...
Phylogenetic reconstructions derived from DNA sequence data play a central role in documenting the number of species complex. Such analyses are pointing to existence many cryptic species, especially poorly understood groups such as genus Limnonectes, and L. kuhlii complex particular. To understand Limnonectes frogs China, we reconstruct major matrilineal genealogy China Southeast Asia based on 12S rRNA, tRNAVal 16S rRNA gene sequences. Based new recognize five including bannaensis,...
Semiaquatic walking has resulted in the evolution of functional and morphological changes various hoofed mammals, such as hippopotamus Brazilian tapir. The biomechanics skilful wetlands or at bottom a waterbody involve medio-lateral opening closing feet to effectively support stabilize body on soft ground reduce water resistance during recovery stroke, respectively. We demonstrate that tapir are mediated by adduction abduction most medial lateral phalanges from CT examination. axial toes,...
Background Venous thromboembolism (VTE) associated with surgery can cause serious comorbidities or death and imposes a substantial economic burden to society. The study examined VTE cases after determined how this condition imposed an on patients based the national health insurance reimbursement database. Methods: This retrospective analysis adopted public payer's perspective. direct medical cost was estimated using data from claims database of Vietnam Jan 1, 2017 Sep 31, 2018. Adult who...
Abstract Despite improvements in medical care, the burden of sepsis remains high. In this study, we evaluated incremental cost associated with postoperative and impact on clinical outcomes among surgical patients Vietnam. We used national database that contained 1,241,893 undergoing seven types surgery. controlled balance between groups using propensity score matching method. Generalized gamma regression logistic were utilized to estimate cost, readmission, reexamination sepsis. The average...
This paper introduces a system to monitor agriculture fields in real time. It includes sensor network for situ data collection and an unmanned aerial vehicle (UAV)) remote sensing. The uses number of nodes measure different parameters the plants environment such as temperature, humidity, nitrogen composition. For communication, LoRa, low-power wide-area modulation technique, that allows receiving signals from at distance up 450 m single receiver. UAV visual near infrared cameras collect...
This study conducted biostatistical multivariate analyses on 23 craniodental morphological measurements from 209 specimens to interspecific variations amongst 15 bat species of the genus Myotis in Vietnam. Univariate and demonstrated that studied can be divided into four groups as follows: extra-large-sized ( M. chinensis ), large-sized pilosus , indochinensis annectans medium-sized altarium hasseltii montivagus horsfieldii ater laniger muricola ) small-sized annamiticus aff. siligorensis,...
In this work, we propose a new approach that combines data from multiple sensors for reliable obstacle avoidance. The include two depth cameras and LiDAR arranged so they can capture the whole 3D area in front of robot 2D slide around it. To fuse these sensors, first use an external camera as reference to combine cameras. A projection technique is then introduced convert point cloud its correspondence. An avoidance algorithm developed based on dynamic window approach. number experiments have...
Accurate species delimitation in Lepus was often hindered by highly conserved morphology and frequent introgression. In this study, we used rigorous molecular methods to evaluate the taxonomic status of Hainan hare (Lepus hainanus) which has been traditionally identified as a distinct species, or subspecies Burmese (L. peguensis). The genetic distance phylogenetic network support L. hainanus peguensis are conspecific. However, concept Bayesian analysis based on combined mtDNA supported they...
Abstract Objectives/Scope Downhole sand exclusion is becoming an essential sandface completion concept for brown fields in Peninsular Malaysia Oil Fields as reservoir pressure declines and formation weakens with production water breakthrough. Additionally, multi-stack reservoirs require good zonal isolation to prevent cross flow between different regime ensure gas breakthrough delayed long possible. As such, Cased Hole Gravel Pack (CHGP) the preferred method many Malaysian fields. However, a...
