With the exploding number of connected objects and sensitive applications, security against side-channel attacks becomes critical in low-cost and low-power IoT applications. For this purpose, established mathematical countermeasures such as masking and shuffling always require a minimum amount of noise in the adversary’s measurements, that may not be guaranteed by default because of good measur...

Disruption of the TGF-β pathway is associated with liver fibrosis and suppression of liver tumorigenesis, conditions associated with low Vitamin D (VD) levels. However, potential contributions of VD to liver tumor progression in the context of TGF-β signaling remain unexplored. Our analyses of VD deprivation (VDD) in in vivo models of liver tumor formation revealed striking three-fold increases...

AIMS Children with congenital complete atrioventricular block (CCAVB) often need pacemaker therapy. In these children, it may be preferable to use single-lead VDD pacing, but for VDD pacing a normal sinus node function is required. Our aim was to study sinus node function in children with CCAVB. METHODS AND RESULTS We longitudinally evaluated sinus rate in 36 children with CCAVB and normal an...

BACKGROUND The hemodynamic advantages of maintaining AV synchrony through AV synchronous pacing are widely known as compared to single chamber pacing. DDD pacemaker implantation entails higher cost and is technically more challenging than the VDD pacemaker. METHODS Seventy one patients underwent VDD lead (Biotronik GmbH, St. Jude Medical and Medtronic Inc.) implantation at KEM hospital, Mumba...

Vitamin A and D deficiencies and insufficiencies are prevalent worldwide in developed and developing countries. Vitamin metabolites are functionally intertwined in that they are high-affinity ligands for related receptors of the nuclear receptor superfamily. The effects of vitamin A deficiencies (VAD) on antibody responses to respiratory virus vaccines have already been demonstrated. Of particu...

sizable errors for gates with highly loaded inputs and lightly loaded outputs [3]. The connection matrix can be used to detect conditions for which there is a transient open path between Vdd and Vss. On every input pattern transition , we check if any node that was connected to Vdd in the old input conguration is connected to Vss in the new one or viceversa. If this condition is veried, short c...

Introduction: Sickle cell disease (SCD) is one of the hereditary blood disorders that affects red cells. Several lines evidence indicated vitamin D deficiency (VDD) quite common in children with SCD and supplementation enhanced health-related quality life these patients. The present study aimed to assess exact prevalence VDD patients using meta-analysis. Materials Methods: A systematic search w...

Background: Orthodontic therapy often causes external root resorption. Serum vitamin D (VD) level is important for tooth mineralization and bone remodeling. This study aimed to test the impact of supplements on remodelling in a deficient rat model following orthodontic retention. Methods Material: 30 male Wistar rats were divided into three groups: control group 10 two experimental groups each ...

Clock distribution networks consume a major portion of the power of a chip . Continuous Scaling of VLSI Technology i.e Channel length ,Supply has lead to integration of millions of transistors on a single chip operating at very high clock frequencies. Besides area and performance, the modern VLSI designs aim at low-power consumption due to limited battery lifetime. Most voltage scaling techniqu...

Phase-contrast magnetic-resonance angiography (PC MRA) generates images of vascular structures as three-dimensional maps of the blood-flow velocity in a volume of interest. To improve visualization methods for PC MRA, radiologists can benefit from image-processing algorithms that can classify flow and stationary tissue. In this paper, I describe a vector-difference distribution (VDD): a statist...
