The paper studies the impact of several lock manager designs on the overhead imposed to a persistent programming language by automated object locking. Our study reveals that a lock management method based on lock state sharing outperforms more traditional lock management designs. Lock state sharing is a novel lock management method that represents all lock data structures with equal values with...

Background: Vaccines are considered the most effective protection against coronavirus disease 2019 (COVID-19). Human Challenge Studies can help to shorten development process of vaccines. The reviewers’ opinions from research ethics committees (REC) play an essential gate-keeping role in determining whether a clinical trial be conducted or not.

D flip flop is one of the fundamental building blocks in most digital designs. Many high speed digital circuits such as memory require high speed and low power consumption. In existing method, the charge keeper is used to provide strong 0 and strong 1 since it uses pass transistor for signal feed through technique. A new D Flip Flop is proposed with signal feed through technique using transmiss...

Power dissipation has become an overriding concern for VLSI circuits and it may come to dominate the total chip power consumption as the technology feature size shrinks. The main aim of this paper is to minimize the leakage power by using a ultra low leakage techniques. In this work we are choosing the Benchmark circuit as full subtractor . This full subtractor are designed by using different t...

We use the term workflow to describe a business process that is executed and managed automatically by a computer system. The definition usually includes all the tasks, tools, procedures, and organizations involved, as well. A workflow management system (WfMS) is an application that uses a computer representation of the workflow logic to define, manage, and execute the process.1 Consider the wor...

We report optimal and asymptotically optimal reversible circuits composed of NOT, CNOT, and Toffoli (NCT) gates, keeping the count by the subsets of the gate types used. This study fine tunes the circuit complexity figures for the realization of reversible functions via reversible NCT circuits. An important consequence is a result on the limitation of the use of the T -count quantum circuit met...

We present a technique to derive depth lower bounds for quantum circuits. The technique is based on the observation that in circuits without ancillæ, only a few input states can set all the control qubits of a To↵oli gate to 1. This can be used to selectively remove large To↵oli gates from a quantum circuit while keeping the cumulative error low. We use the technique to give another proof that ...

MANY PEOPLE ARE CONCERNED THAT ACCOUNTable care organizations (ACOs) and other delivery system reforms in the Affordable Care Act will simply bring back the managed care days of the 1990s. These skeptics suspect that payment reforms to control high and increasing costs will simply lead to gate keeping and service denial rather than the promise of care redesign and coordination that removes unne...
