OBJECTIVES To evaluate the possible synergistic interaction of collagen-adenosine diphosphate and collagen-epinephrine in aggregation of human platelets. METHODS An experimental study was carried out at Armed Forces Instiute of Pathology, Rawalpindi, Pakistan, from June 2001 to December 2002. The platelet aggregation was determined by means of turbidometric method, which measures changes in o...

One common design for routing protocols in mobile ad hoc networks is to use positioning information. We combine the class of randomized position-based routing strategies called AB (Above-Below) algorithms with face routing to form AB:Face2:AB routing algorithms, a new class of hybrid routing algorithms in mobile ad hoc networks. Our experiments on unit disk graphs, and their associated Yao sub-...

As process technology shrinks, the adaptive leakage power compensation scheme will become more important in realizing high-performance and low-power applications. In order to minimize total active power consumption in digital circuits, one must take into account sub-threshold leakage currents that grow exponentially as technology scales. This describes to predict how dynamic power and sub-thres...

A correlation between the gated-diode R-G current and the performance degradation of SOI n-channel MOS transistor after F-N stress test has been demonstrated in this paper. Due to increase of interface traps after F-N stress test, the generation-recombination (R-G) current of the gateddiode in the SOI-MOSFET architecture increases while the performance characteristics of MOSFET transistor such ...

Double Gate FinFET devices are suitable for nano electronic circuits due to better scalability, higher on-current (Ion), improved Sub-threshold Slope (SS) and undoped body (no random dopant fluctuation). Body thickness (TSi) increases the gate control over the channel resulting in reduced short channel effects (SCEs). Thin Tsi increases the quantum confinement of charge, resulting increased thr...

Correction for ‘Impact of changes in bond structure on ovonic threshold switching behaviour GeSe2’ by Jonas Keukelier et al., J. Mater. Chem. C, 2021, DOI: 10.1039/d0tc04086j.

In this paper a technique is presented which improves the noise immunity of TSPC circuit. This technique is compared with other existing techniques. Analysis is carried out both for super and sub-threshold regions of operation. Investigations consider different performance criteria viz. n ooise immunity curve, power consumption, delay, average noise threshold energy (ANTE),

With the rapid scaling down of CMOS manufacturing technology, the reduction in leakage power has become an important concern in low voltage, low power and high performance applications. In this paper a novel circuit design technique is presented which minimizes sub-threshold leakage current by zeroing drain-source voltage. This results in a reduction of leakage power consumption in sleep mode e...

This paper presents fingerprint indexing based on graph information of minutiae, fingerprint classification and verification based on hierarchical agglomerative clustering technique. The proposed fingerprint indexing is invariant under translation and rotation. Its performance is evaluated in terms of several real-life datasets. The fingerprint database is clustered into five classes based on t...

Do texture-sensitive mechanisms operate separately on, or pool, luminance and colour contrast information? We addressed this question by measuring threshold-versus-amplitude functions for orientation-modulated (OM) gratings comprised of gabor elements defined by either colour or luminance contrast. In both the uncrossed (all elements in test and mask defined by either colour or luminance contra...
