A Novel Infrastructure Design of Industrial Autonomous System
Quang Thinh Truong,Ha Quang Thinh Ngo,Thanh Phuong Nguyen,Hung Nguyen,Won-Ho Kim 한국지능시스템학회 2019 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.19 No.2
In this era, the integrated technologies in a unit bring huge benefits for customers. In this paper, a novel design of structure for autonomous system is illustrated. It is superior by combining the specifications of various types in commercial market. As a result, numerous advantages of systems are converged into unified unit. The design of autonomous platform consists of hardware components and infrastructure. Later, the modeling of autonomous system is simulated on computer to fit with proposed design. The implementation of control scheme into model is to drive autonomous system to complete mission. From simulation results, it can be seen that the proposed strategy is feasible, effective and capable in reality.
Meso-Rex Bypass in Treatment for Extrahepatic Portal Vein Obstruction in Children: A Case Report
( Thinh Ly ),( Can Ta ),( Xuyen Nguyen ) 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1
Aims: Current management of extrahepatic portal hypertension comprises endoscopic eradication therapy of esophageal varices and conventional shunt surgery. This report assess the early outcome of Mesorex bypass and report their results here. Methods: Case report: A case of a boy had portal hypertension with hypersplenism and recurrent bleeding from esophageal varices. Preoperative evaluation included blood test, liver function tests, hepatic duplex ultrasonography, computed tomography, computed tomography angiography. The internal jugular vein was used as vein graft in the patient. Results: The platelet count increased within 4 weeks from a mean of 121.1 x 103 /μL to 150.2 x 103/μL. Ultrasound revealed sufficient perfusion in all shunts (median 32 cm/s). The intrahepatic portal perfusion in segment 4 improved postoperatively. Conclusions: This study reports the intial result of Mesorex bypass for treatment extrahepatic portal hypertension. The advantageous of technique is restoration of portal flow as porto-systemic shunt. This technique may be used for atresia of portal vein or extrahepatic portal vein obstruction by thrombosis.

<P><B>Abstract</B></P><P>Poly(<I>N</I>‐vinylcarbazole) (PVK) composites containing different concentrations of multiwalled carbon nanotube (MWCNT) were synthesized through the oxidative polymerization of <I>N</I>‐vinylcarbazole with ferric chloride. The synthesized composites were characterized using Fourier transform infrared spectroscopy, ultraviolet‐visible spectra, and thermogravimetric analysis. A honeycomb‐patterned film was fabricated by casting the PVK–MWCNT composite solution under humid conditions. The morphology of the honeycomb‐patterned films in the PVK–MWCNT polymer composites and the dependence of its pore diameter and pore height on MWCNT concentration were analyzed using scanning electron microscopy. The honeycomb‐patterned films were treated at 150, 250, 400, and 490°C to study the arrangement of MWCNTs in the patterned films and to measure the DC conductivity depending on the calcination temperature. DC conductivity of the patterned films was increased by increasing the concentration of MWCNT in the composites and in the increased pretreatment temperature. POLYM.

Joint Relay Selection and Power Allocation for Two-Way Relaying with Physical Layer Network Coding
Thinh Phu Do,Jin Soo Wang,Iickho Song,Yun Hee Kim IEEE 2013 IEEE COMMUNICATIONS LETTERS Vol.17 No.2
<P>We consider a two-way relay (TWR) network with multiple relays, where the relays adopt physical layer network coding based on decode-and-forward. A joint relay selection and power allocation (RS-PA) scheme is proposed to improve the symbol error probability (SEP) of the TWR network using BPSK modulation under the total power constraint. For the proposed scheme and the benchmark scheme performing RS without PA, the average SEP of the TWR network is derived analytically and confirmed with simulation results. It is shown that the proposed scheme provides an asymptotic SNR gain of about 1.76 dB over the benchmark scheme at the same diversity order.</P>

The first crystal structure of a pyrroloquinoline quinone (PQQ)-dependent methanol dehydrogenase (MDH) from a marine methylotrophic bacterium, Methylophaga aminisulfidivorans MPT (MDHMas), was determined at 1.7 Å resolution. The active form of MDHMas (or MDHIMas) is a heterotetrameric α2β2, where each β-subunit assembles on one side of each of the α-subunits, in a symmetrical fashion, so that two β-subunits surround the two PQQ-binding pockets on the α-subunits. The active site consists of a PQQ molecule surrounded by a β-propeller fold for each α-subunit. Interestingly, the PQQ molecules are coordinated by a Mg2+ ion, instead of the Ca2+ ion that is commonly found in the terrestrial MDHI, indicating the efficiency of osmotic balance regulation in the high salt environment. The overall interaction of the β-subunits with the α-subunits appears tighter than that of terrestrial homologues, suggesting the efficient maintenance of MDHIMas integrity in the sea water environment to provide a firm basis for complex formation with MxaJMas or Cyt cL. With the help of the features mentioned above, our research may enable the elucidation of the full molecular mechanism of methanol oxidation by taking advantage of marine bacterium-originated proteins in the methanol oxidizing system (mox), including MxaJ, as the attainment of these proteins from terrestrial bacteria for structural studies has not been successful.
