The important aspect of all verification system is authentication and security. This aspect necessitates the development of a method that ensures user security and privacy. The traditional methods such as tokens and passwords provide security to the users. Uncertainly, the attackers can easily compromise these techniques. In recent years, the combination of biometrics and cryptography technique...

BACKGROUND Serum infliximab (IFX) and antibody-to-infliximab (ATI) levels are objective parameters, that may have a great role in the therapeutic decisions during maintenance biological therapy. RESEARCH DESIGN AND METHODS 48 inflammatory bowel disease patients receiving maintenance IFX therapy were prospectively enrolled and divided into adequate (complete remission N = 20) and inadequate re...

We consider, theoretically and experimentally, several alternative mechanisms to allocate assets when the future value of an asset is unknown at the time of allocation because of strategic uncertainty. We compare the performance of auctions (bidding with money) for the right to play the minimum effort coordination game with a competitive allocation process where participants bid with game actio...

Fluorescence interference contrast microscopy (FLIC) is a powerful method to structurally characterize fluorescent objects with nanometer-scale resolution in the z direction. Here we use FLIC to characterize the water layer underlying supported membranes and membrane-tethered double-stranded oligonucleotides. FLIC measurements of supported membranes containing the lipid-anchored fluorescent dye...

Cloud-based applications benefit from the scalability and efficiency offered by server consolidation and shared facilities. However, the shared nature of cloud infrastructures may introduce threats stemming from the co-location and combination of untrusted components, in addition to typical risks due to the inevitable presence of weaknesses in the infrastructure itself. As a result, adversaries...

Introduction Our work was focused on document retrieval from Scopus databases of the Escuela de Ingeniería de Sistemas y Computación (EISC) of the Universidad del Valle (Cali Colombia). The databases systems as WoS (Web of Science) or Scopus contain the knowledge produced by engineer schools. However, this information is ambiguous and the retrieving of the specific documents of one school is id...

Introduction Abnormalities of posture are a common cause of pain and disability. The range of effect from discomfort to incapacitating disability is related both to the severity as well as to the persistence of the faults (Kendall, 1993). On the whole, objective measurement systems for postural evaluation are not widely accessible in the UK especially on the National Health Service (Warren et a...

In this paper a theory is developed that provides the sampling distribution of alleles at a diallelic marker locus closely linked to a low-frequency allele that arose as a single mutant. The sampling distribution provides a basis for maximum-likelihood estimation of either the recombination rate, the mutation rate, or the age of the allele, provided that the two other parameters are known. This...

Integrated low-frequency oscillators can replace crystal oscillators as sleep-mode timers to reduce the size and cost of wireless sensors [1]. Since the timer is one of the few continuously functioning circuits, minimizing its power consumption can greatly reduce sleep-mode power of highly duty-cycled systems. Temperature stability of the oscillator is important in order to minimize timing unce...

Wavelet transforms is a very powerful tools for image compression. One of its advantage is the provision of both spatial and frequency localization of image energy. However, wavelet transform coefficients are defined by both a magnitude and sign. While algorithms exist for efficiently coding the magnitude of the transform coefficients, they are not efficient for the coding of their sign. It is ...
