N. H. Dashti,M. S. Montasser,N. Y. Ali,R. G. Bhardwaj,D. L. Smith 한국식물병리학회 2007 Plant Pathology Journal Vol.23 No.2

To overcome the problem of the yield reduction due to the viral satellite mediated protection, a culture mix of three nitrogen-fixing bacteria species of the genus Azospirillum (A. brasilienses N040, A. brasilienses SP7, and A. lipoferum MRB16), and one strain of cyanobacteria (Anabena oryzae Fritsch) were utilized as biofertilizer mixture in both greenhouse and field experiments. When protected plants were treated with biofertilizer mixtures, the fruit yield of biofertilized plants increased by 48% and 40% in a greenhouse and field experiment, respectively, compared to untreated plants inoculated with the protective viral strain alone. Polyacrylamide gel electrophoresis (PAGE) analysis of total nucleic acid (TNA) extracts revealed that biofertilization did not affect the accumulation of the viral satellite RNA (CARNA 5) that is required for plant protection against other destructive viral strains of CMV. The yield increment was a good compensation for the yield loss caused by the use of the protective viral strain associated with CARNA 5.

<P>A calcium molybdate (CaMoO4) crystal scintillator, with molybdenum enriched in Mo-100 and calcium depleted in Ca-48 ((CaMoO4)-Ca-40-Mo-100), was developed by the Advanced Molybdenum based Rare process Experiment (AMoRE) collaboration to search for a neutrinoless double beta (0 nu beta beta) decay of Mo-100. We are planning to use about 10 kg of (CaMoO4)-Ca-40-Mo-100 crystals as cryogenic bolometers for the first phase of the experiment (AMoRE-I) at the Yang Yang underground laboratory (Y2L) in Korea. This experiment calls for an extremely low level of radioactive contamination in detectors, particularly by thorium, uranium, and radium decay chains. We measured scintillation properties and radioactive contamination of CaMoO4 and (CaMoO4)-Ca-40-Mo-100 crystals at the Y2L. We also estimated the acceptable level of internal radioactive background using Monte Carlo simulation for the AMoRE-I.</P>

Park, J.Y.,Rha, S.W.,Choi, B.,Choi, J.W.,Ryu, S.K.,Kim, S.,Noh, Y.K.,Choi, S.Y.,Akkala, R.G.,Li, H.,Ali, J.,Xu, S.,Ngow, H.A.,Lee, J.J.,Lee, G.N.,Kim, J.,Lee, S.,Na, J.O.,Choi, C.U.,Lim, H.E.,Kim, J.W Elsevier/North-Holland Biomedical Press 2015 INTERNATIONAL JOURNAL OF CARDIOLOGY Vol.184 No.-

Background: High dose atorvastatin is known to be associated with new onset diabetes mellitus (NODM) in patients with high risk for developing diabetes mellitus (DM). However, low dose atorvastatin is more commonly used as compared with high dose atorvastatin. The aim of this study is to investigate the impact of low dose atorvastatin (LDA, 10mg or 20mg) on the development of NODM up to three years in Asian patients. Methods: From January 2004 to September 2009, we investigated a total of 3566 patients who did not have DM. To adjust for potential confounders, a propensity score matching (PSM) analysis was performed using the logistic regression model. After PSM (C-statistics: 0.851), a total of 818 patients (LDA group, n=409 patients and control group, n=409 patients) were enrolled for analysis. Results: Before PSM, the cumulative incidence of NODM (5.8% vs. 2.1%, p<0.001), myocardial infarction (0.5% vs. 0.1%, p-value=0.007), and major adverse cardio-cerebral event (MACCE, 1.8% vs. 0.7%, p-value=0.012) at three-years were higher in the LAD group. However, after PSM, there was a trend toward higher incidence of NODM (5.9% vs. 3.2%, p=0.064) in the LDA group, but the incidence of MACCE (1.2% vs. 1.5%, p-value=1.000) was similar between the two groups. In multivariable analysis, the LDA administration was tended to be an independent predictor of NODM (OR: 1.99, 95% CI: 1.00-3.98, p-value 0.050). Conclusions: In this study, the use of LDA tended to be a risk factor for NODM in Asian patients and reduced clinical events similar to the control group. However, large-scale randomized controlled trials will be needed to get the final conclusion.

Examination of the Earthquake (Samos Island) in Izmir (30.10.2020) by Using Cors-Tr GNSS Observations and InSAR Data

Atınç Pırtı,Ramazan Gürsel Hoşbaş,Mehmet Ali Yücel 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.1

Izmir, which is one of the biggest cities of Turkey and has the extensive tectonic features of the Western Anatolia region, has been struck in recent years due to its high seismic activity. In particular, the south of Izmir is one of the regions that has high seismic activity in the city, which is constrained by major fault zones. The earthquake of magnitude of a Mw 6.9 occurred 8 km north of Samos Island at a depth of 16 km on 30.10.2020, at 11:51:24 UTC (14:51:24 Local Time (LT)). It occurred on a 40-kilometer-long north-dipping normal fault zone in the Mediterranean between Greece's Samos Island and Turkey's Kuşadası Bay. Following the mainschock, a tsunami with a height of more than 1 meter occurred at Sığacık Bay, south of Izmir, and on the north side of Samos Island. This article focuses on the investigation of the Samos earthquake by utilizing both GNSS data and InSAR images, and the obtained results are given in this paper. GNSS data were processed by using CSRS-PPP Software as static and kinematic modes. After processing the GNSS data, the maximum displacements were observed at CESME and IZMIR CORS-TR points located in the north of the fault. Horizontal movements of 12 cm and 6 cm towards the north were obtained at CESME and IZMIR points, respectively. However, the amount of horizontal movements was less at DIDIM and AYDIN CORS-TR locations, which are located to the south of the fault. In addition to GNSS data, ESA Sentinel-1 SAR data was used in the InSAR procedure, and the displacements were clarified using the unwrapped interferogram. The interferogram revealed a 10 cm uplift in the west of the Island of Samos and a 10 cm subsidence in the Izmir region, on the north side of the fault, based on the InSAR data. The most striking feature of this studyis that the earthquake that occurred near the island of Samos was reported by Gansas' study that the 3 GNSS points (SAMO, SAMU, and 093A) on the island of Samos are moving in a south direction and the largest displacement is about 36 centimetres south. However, in our study, the north direction is more prominent as the direction of movement at IZMIR and CESME points. The movement at the DIDIM point supports his work. In other words, the Samos Fault affected the points located in the north and south differently.

Evaluating the Accuracy of Determining Coordinates of Corners of the Building Surveyed in Tilt Technology

Atınç Pırtı,Mehmet Ali Yücel 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.6

Integrated Inertial Measurement Unit (IMU) and electronic compass; small, sturdy form factor; supports all communications, satellites, and constellations (Revolutionary 9 axis IMU and ultra-compact 3-axis e-Compass). By integrating a 9-axis IMU with a digital compass, the Topcon Hiper Versatile Global Navigation Satellite System (VR GNSS) receiver can correct for up to 15 degrees of pole tilt. It may be now measured all the way to the edge/corner of a building without requiring an offset. The emerging technology makes up for the fact that plum field surveys can be off by up to 15 degrees. The accuracy of measured building corners is investigated in this study using Topcon Inertial Levelling Technology (TILT) in the IMU and e-Compass. The results of a case study of 5, 10, 15 degree tilt angles show that a 3D positioning accuracy of about 10 cm is achievable even when the pole is tilted.

Multiplex bioimaging of piRNA molecular pathway-regulated theragnostic effects in a single breast cancer cell using a piRNA molecular beacon

Lee, Y.J.,Moon, S.U.,Park, M.G.,Jung, W.Y.,Park, Y.K.,Song, S.K.,Ryu, J.G.,Lee, Y.S.,Heo, H.J.,Gu, H.N.,Cho, S.J.,Ali, B.A.,Al-Khedhairy, A.A.,Lee, I.,Kim, S. IPC Science and Technology Press 2016 Biomaterials Vol.101 No.-

<P>Recently, PIWI-interacting small non-coding RNAs (piRNAs) have emerged as novel cancer biomarkers candidate because of their high expression level in various cancer types and role in the control of tumor suppressor genes. In this study, a novel breast cancer theragnostics probe based on a single system targeting the piRNA-36026 (piR-36026) molecular pathway was developed using a piR-36026 molecular beacon (MB). The piR-36026 MB successfully visualized endogenous piR-36026 biogenesis, which is highly expressed in MCF7 cells (a human breast cancer cell line), and simultaneously inhibited piR-36026-mediated cancer progression in vitro and in vivo. We discovered two tumor suppressor proteins, SERPINA1 and LRAT, that were directly regulated as endogenous piR-36026 target genes in MCF7 cells. Furthermore, multiplex bioimaging of a single MCF7 cell following treatment with piR-36026 MB clearly visualized the direct molecular interaction of piRNA-36026 with SERPINAI or LRAT and subsequent molecular therapeutic responses including caspase-3 and PI in the nucleus.

Effect of Manganese Promotion on Al-Pillared Montmorillonite Supported Cobalt Nanoparticles for Fischer-Tropsch Synthesis

N. Ahmad,S. T. Hussain,B. Muhammad,N. Ali,S. M. Abbas,Y. Khan 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.10

The effect of Mn-promotion on high surface area Al-pillared montmorillonite (AlMMT) supported Co nanoparticles prepared by hydrothermal method have been investigated. A series of different weight% Mnpromoted Co nanoparticles were prepared and characterized by XRD, TPR, TGA, BET and SEM techniques. An increase in the surface area of MMT is observed with Al-pillaring. Fischer-Tropsch catalytic activity of the as prepared catalysts was studied in a fixed bed micro reactor at 225 oC, H2/CO = 2 and at 1 atm pressure. The data showed that by the addition of Mn the selectivity of C1 dropped drastically while that of C2-C12 hydrocarbons increased significantly over all the Mn-promoted Co/AlMMT catalysts. The C13-C20 hydrocarbons remained almost same for all the catalysts while the selectivity of C21+ long chain hydrocarbons decreased considerably with the addition of Mn. The catalyst with 3.5%Mn showed lowest C21+ and highest C2-C12 hydrocarbons selectivity due to cracking of long chain hydrocarbons over acidic sites of MMT.

Ali, R.,Shahin, N.,Kim, Y.-T.,Kim, B.-S.,Kim, S.W. Institution of Electrical Engineers 2018 Electronics letters Vol.54 No.10

<P>A channel observation-based scaled backoff (COSB) mechanism for the carrier sense multiple access with collision avoidance of high efficiency wireless local area networks (WLANs) is devised. The proposed protocol modifies the blind scaling of contention window (W) in binary exponential backoff (BEB) scheme of currently deployed WLANs. COSB is employed to adaptively scale-up and scale-down the W size during the backoff mechanism for collided and successfully transmitted data frames, respectively. It can achieve higher throughput and shorter delay compared to the conventional BEB mechanism in highly dense WLANs.</P>
