Quantum search algorithms have been shown to deliver quadratic speedups over classical ones. The authors propose a generalized form of such through the use ``quantum amplitude-amplification operators'' (QAAOs), with goal implementing them on near-term quantum devices. They demonstrate three-qubit examples cloud-based computing services, and their framework distinguish between exact fixed-point ...

Mutations in genes important for the preservation of genome stability can increase the frequency of gene amplification, a process relevant to tumor development. To investigate whether telomerase, the enzyme deputed to telomere maintenance, also plays a role in gene amplification, we studied the amplification of the carbamyl-P-synthetase, aspartate transcarbamilase, dihydro-orotase (CAD) gene in...

CPA is a class of isothermal amplification reactions that is carried out by a strand displacement DNA polymerase and does not require an initial denaturation step or the addition of a nicking enzyme. At the assay temperature of 63°C, the formation of a primer-template hybrid at transient, spontaneous denaturation bubbles in the DNA template is favored over re-annealing of the template strands b...

Sperm typing is an effective way to study recombination rate on a fine scale in regions of interest. There are two strategies for the amplification of single meiotic recombinants: repulsion-phase allele-specific PCR and whole genome amplification (WGA). The former can selectively amplify single recombinant molecules from a batch of sperm but is not scalable for high-throughput operation. Curren...

This paper presents the preliminary results of an extensive parametric study on seismic response of two-dimensional semi-sine shaped hills to vertically propagating incident P- and SV-waves. Clear perspectives of the induced diffraction and amplification patterns are given by investigation of time-domain and frequency-domain responses. It is shown that site geometry, wave characteristics , and ...

ABSTRACT Recently, PCR is being reported more frequently with satisfactory results on the diagnosis of clinical infections. Widespread availability of PCR promises a sensitive and specific alternative, to traditional methods, but these benefits must be balanced against cost. Protocols using small volumes have described where the reaction taken place in capillary tubes, and small volumes work...

Case Amplification can improve the accuracy of a collaborative filtering (CF) algorithm with no extra space overhead by amplifying the effect of close candidates in the prediction. However, in a cold start scenario, the traditional Case Amplification on an item-based prediction can reduce accuracy. Given a small known set, Case Amplification can give a mediocre candidate an unsuitable amplifica...
