PURPOSE To prospectively evaluate whether cardiac gating can improve the reproducibility of intravoxel incoherent motion (IVIM) parameters in the head and neck, we performed IVIM diffusion-weighted imaging (DWI) using 4 b values (4b), 4 b values with cardiac gating (4b gating) and 17 b values (17b). METHODS We performed IVIM DWI twice per person on nine healthy volunteers using 4b, 4b gating ...

Almost all power-gating circuits used in MOS current-mode circuits were realized with dual-rail schemes. In this paper, a power-gating scheme for single-rail MOS current mode logic (SRMCML) is presented. The modeling of the sleep transistor in power-gating circuits is constructed and analyzed. The optimization methods for sizing sleep transistors of power-gating circuits are addressed in terms ...

Casting has many process variations depending upon the material, the type of pattern, mould and the pouring technique like sand casting, investment casting, die casting, squeeze casting and lost foam casting. Sand casting is the most widely used process which can be used to produce intricate parts in almost every metal that can be melted. Casting defects analysis is process of finding the root ...

The open-close states of the ion channels in a living system are regulated by multiple stimuli such as ligand, pH, potential and light. Functionalizing natural channels by using synthetic chemistry would provide biological nanopores with novel properties and applications. Here we use para-sulfonato-calix[4]arene-based host-guest supramolecular system to develop artificial gating mechanisms aimi...

This paper describes design of high energy efficiency 32 bit parallel processor core using instructtion-levels data gating and dynamic voltage scaling (DVS) techniques. We present instruction-levels data gating technique. We can control activation and switching activity of the function units in the proposed data technique. We present instruction-levels DVS technique without using DC-DC converte...

An analysis of the efficiency of power-gating for clock storage elements (CSE) is presented. Two CSE topologies: the TGMS (Transmission Gate Master Slave) and the WPMS (Write Port Master Slave) are examined along with their respective circuits with sleep transistors. In this work, we study the benefits of adding sleep transistors coupled with regular clock-gating during inactive mode. We examin...

The orphan GluD2 receptor belongs to the ionotropic glutamate receptor family but does not bind glutamate. Ligand-gated GluD2 currents have never been evidenced, and whether GluD2 operates as an ion channel has been a long-standing question. Here, we show that GluD2 gating is triggered by type 1 metabotropic glutamate receptors, both in a heterologous expression system and in Purkinje cells. Th...

Intrinsically microporous polyamines (PIM-EA-TB) provide tertiary amine binding sites for protons and in this way allow switching/gating from a low ionic conductivity state to semipermeable anion through micropores. In ethanolic NaClO4 media PIM-EA-TB films (approx. 10 μm thick; deposited asymmetrically onto diameter microhole 5 thick Teflon) is lowered by ion exclusion compared observed aqueou...
