Faisal T Abu-Nimeh, Woon-Seng Choong
Link efficiency, data integrity, and continuity for high-throughput and real-time systems is crucial. Most of these applications require specialized hardware and operating systems as well as extensive tuning in order to achieve high efficiency. Here, we present an implementation of gigabit Ethernet data streaming which can achieve 99.26% link efficiency while maintaining no packet losses. The design and implementation are built on OpenPET, an opensource data acquisition platform for nuclear medical imaging, where (a) a crate hosting multiple OpenPET detector boards uses a User Datagram Protocol over Internet Protocol (UDP/IP) Ethernet soft-core, that is capable of understanding PAUSE frames, to stream data out to a computer workstation; (b) the receiving computer uses Netmap to allow the processing software (i...

Mechanistic control is a powerful means for manufacturing specific shapes of metal nanostructures and optimizing their performance in a variety of applications. Thus, we successfully synthesized multimetallic nanoplates (PtAgBiCo and PtAgBi) by combining the concepts of crystal symmetry, oxidative etching and seed ratio, and tuned their activity, stability and methanol tolerance, as well as Pt utilization, for the oxygen reduction reaction in direct methanol fuel cells. Systematic studies reveal that the formation of PtAgBiCo triangular nanoplates with a high morphological yield (>90%) can be achieved by crystallinity alteration, while electrochemical measurements indicate that the PtAgBiCo nanoplates have superior electrocatalytic activity towards the oxygen reduction reaction...

Metallo-β-lactamases (MBLs) are zinc ion dependent enzymes that are responsible for the emergence and spread of β-lactam resistance among bacterial pathogens. There are uncharacterized putative MBLs in the environment and their emergence is major interference in the generation of universal MBL inhibitors so it is important to identify and characterize novel MBLs. In this study two novel MBLs from Luteimonas sp. J29 and Pseudoxanthomonas mexicana were identified using B3 MBLs as query in BLAST database search...

REVIEW
Faisal Rahman, John W McEvoy
PURPOSE OF REVIEW: The definition and treatment of hypertension have both changed dramatically over the last century, with recent trials suggesting benefit for lower blood pressure (BP) targets than ever before considered. However, tempering the enthusiasm for more intensive BP targets are long-held concerns that BP reduction below a certain threshold may pose dangers, the so-called "J-curve." In this review, we summarize the evidence for a J-curve in the treatment of hypertension. RECENT FINDINGS: The Systolic Blood Pressure Intervention Trial (SPRINT) reported that achieving a systolic BP target of 120 mmHg reduces cardiovascular disease in high-risk individuals, supporting more intensive BP reduction...

Little information is available about autism spectrum disorder services in the Kingdom of Saudi Arabia. A sample of 205 parents completed an online survey about the use of autism spectrum disorder services for their children. The results revealed that on average, children began services by 3.3 years. Most parents reported utilizing non-medical treatments followed by biomedical treatments and cultural and religious treatment. The age at the initiation of services and the type of treatments used differed by parent's income, educational attainment, the extent of knowledge about autism spectrum disorders, and geographic location...

Among transposable elements (TEs), the LTR retrotransposons are abundant followed by non-LTR retrotransposons in plant genomes, the lateral being represented by LINEs and SINEs. Computational and molecular approaches were used for the characterization of Brassica LINEs, their diversity and phylogenetic relationships. Four autonomous and four non-autonomous LINE families were identified and characterized from Brassica. Most of the autonomous LINEs displayed two open reading frames, ORF1 and ORF2, where ORF1 is a gag protein domain, while ORF2 encodes endonuclease (EN) and a reverse transcriptase (RT)...

Previous studies revealed that phosphate, as an additive to composting, could significantly reduce NH3 emission and nitrogen loss through change of pH and nitrogen fixation to form ammonium phosphate. However, few studies have explored the influence of pH change and phosphate additive on NO x(-)-N, NH4(+)-N, NH3, and N2O, which are dominate forms of nitrogen in composting. In this study, the equimolar H3PO4, H2SO4, and K2HPO4 were added into pig manure composting to evaluate the effect of H(+) and PO4(3-) on nitrogen transformation...

Proportional-integral-derivative (PID) control is widely practised as the base layer controller in the industry due to its robustness and design simplicity. However, a supervisory control layer over the base layer, namely a model predictive controller (MPC), is becoming increasingly popular with the advent of computer process control. The use of a supervisory layer has led to different control structures. In this study, we perform an objective investigation of several commonly used control structures such as 'Cascaded PI controller', 'DMC cascaded to PI' and 'Direct DMC'...
