Fabric analysis of the upper 1300m of the Dome C ice core reveals a slight clustering tendency of c axes towards vertical, which gradually enhances with depth from an initially isotropic orientational distribution of c axes at the free surface. Such a strain induced anisotropy is compatible with the expected macroscale stress state in a dome, viz. dominated by vertical compression. Yet, when on...

BACKGROUND Corticosteroids increase risk for decreased bone mineral density, which can be worsened by vitamin D insufficiency (VDI) or deficiency (VDD). PROCEDURE In the Vanderbilt cancer survivorship clinic, we obtained screening total 25-hydroxy vitamin D levels (VDL) in 171 cancer survivors <23 years old who were treated with prolonged corticosteroids for their cancer, and compared this gr...

Dependence of within-die delay variations on power supply voltage (VDD) is measured down to 0.4 V. The VDD dependence of the within-die delay variation of manual layout and irregular auto place and route (P&R) layout are compared for the first time. The measured relative delay (=sigma/average) variation difference between the manual layout and the P&R layout decreases from 1.56% to 0.07% with r...

Vitamin D and calcium are important nutrients for skeletal growth and bone health. Children and pregnant women are particularly vulnerable to 25-hydroxy vitamin D deficiency (VDD). VDD, with or without dietary calcium deficiency, can lead to nutritional rickets (NR), osteomalacia, and disturbances in calcium homeostasis. Multiple studies have linked VDD to adverse health outcomes in both childr...

A post-fabrication dual supply voltage (VDD) control (PDVC) of multiple voltage domains is proposed for a minimum operating voltage (VDDmin)-limited ultra low voltage logic circuits. PDVC effectively reduces an average VDD below VDDmin, thereby reducing the power consumption of logic circuits. PDVC is applied to a DES CODEC’s circuit fabricated in 65nm CMOS. The layout of DES CODEC’s is divided...

Field Programmable Gate Arrays (FPGAs) with supply voltage (Vdd) programmability have been proposed recently to reduce FPGA power, where the Vdd-level can be customized for FPGA circuit elements and unused circuit elements can be power-gated. In this paper, we first design novel Vddprogrammable and Vdd-gateable interconnect switches with minimal number of configuration SRAM cells. We then evalu...

Illusory self-motion (vection) can be generated by visual stimulation. The purpose of the present study was to compare behavioral vection measures including intensity ratings, duration, and onset time across different visual display types. Participants were exposed to a pattern of alternating black-and-white horizontal or vertical bars that moved either in vertical or horizontal direction, resp...

OBJECTIVE Vitamin D deficiency (VDD) in pregnant women and their children is an important health problem with severe consequences for the health of both. Thus, the objectives of this review were to reassess the magnitude and consequences of VDD during pregnancy, lactation and infancy, associated risk factors, prevention methods, and to explore epigenetic mechanisms in early fetal life capable o...

BACKGROUND Vitamin D deficiency (VDD) has been hypothesized not only to be common but also to represent a potentially modifiable risk factor for greater illness severity and clinical outcome during critical illness. The objective of this systematic review was to determine the frequency of VDD in pediatric critical illness and its association with clinical outcomes. METHODS MEDLINE, Embase, an...

Even though system-on-chip (SoC) testing at multiple voltage settings significantly increases test complexity, the use of a different shift frequency at each voltage setting offers parallelism that can be exploited by time-division multiplexing (TDM) to reduce test length. We show that TDM is especially effective for small-bitwidth and heavily loaded test-access mechanisms (TAMs), thereby tangi...
