Thermally Activated Reversible Threshold Shifts in Yba\u3csub\u3e2\u3c/sub\u3eCu\u3csub\u3e3\u3c/sub\u3eO\u3csub\u3e7-ÎŽ\u3c/sub\u3e/Yttria-Stabilized Zirconia/Si Capacitors
Yba2Cu3O7-ÎŽ/yttriaâstabilized zirconia (YSZ)/silicon superconductorâinsulatorâsemiconductor capacitors are characterized with capacitanceâvoltage (CâV) measurements at different gateâvoltage sweep rates and under biasâtemperature cycling. It is shown that ionic conduction in YSZ causes both hysteresis and stretchâout in roomâtemperature CâV curves. A thermally activated process with an activation energy of about 39 meV in YSZ and/or at YSZ/Si interface is attributed to trapping/detrapping mechanisms in the SiOx interfacial layer between YSZ and Si. The negative mobile ions in YSZ can be moved by an applied electric field at room temperature and then ââfrozenââ with decreasing temperature, giving rise to adjustable threshold voltages at low temperatures
Genome-wide association study identifies multiple susceptibility loci for pancreatic cancer
We performed a multistage genome-wide association study including 7,683 individuals with pancreatic cancer and 14,397 controls of European descent. Four new loci reached genome-wide significance: rs6971499 at 7q32.3 (LINC-PINT, per-allele odds ratio (OR) = 0.79, 95% confidence interval (CI) 0.74-0.84, P = 3.0 x 10(-12)), rs7190458 at 16q23.1 (BCAR1/CTRB1/CTRB2, OR = 1.46, 95% CI 1.30-1.65, P = 1.1 x 10(-10)), rs9581943 at 13q12.2 (PDX1, OR = 1.15, 95% CI 1.10-1.20, P = 2.4 x 10(-9)) and rs16986825 at 22q12.1 (ZNRF3, OR = 1.18, 95% CI 1.12-1.25, P = 1.2 x 10(-8)). We identified an independent signal in exon 2 of TERT at the established region 5p15.33 (rs2736098, OR = 0.80, 95% CI 0.76-0.85, P = 9.8 x 10(-14)). We also identified a locus at 8q24.21 (rs1561927, P = 1.3 x 10(-7)) that approached genome-wide significance located 455 kb telomeric of PVT1. Our study identified multiple new susceptibility alleles for pancreatic cancer that are worthy of follow-up studies
Genome-wide association study identifies multiple susceptibility loci for pancreatic cancer
We performed a multistage genome-wide association study (GWAS) including 7,683 individuals with pancreatic cancer and 14,397 controls of European descent.

Effects of Bias-Temperature Cycling on Electrical Characteristics of YBCO/YSZ/Si MIS Capacitors
A bias-temperature cycling technique is developed in the electrical characterization of YBa2Cu307âÎŽ/yttria-stabilized zirconia (YSZ)/Si capacitors. This technique can be used to determine the electrical properties of the material components and their interfaces in the capacitor. Capacitance-voltage (C-V) measurements under no or weak illumination at temperatures ranging from 295 to 80K reveal that hysteresis due to mobile ions decreases with cooling and become vanishingly small at about 220K. Upon further cooling, a different mechanism due to traps in the YSZ/Si interface dominates the low-temperature hysteresis and stretchout of the C-V curves, which is evidenced by measurements for the illuminated device at 80K
