Purpose: 9p21 is a major target in the pathogenesis of human urinary bladder cancer. The locus harbors the CDKN2A/ARF tumor suppressor gene, which encodes two cell cycle regulatory proteins cyclin dependent kinase 2A (p16) and alternate reading frame (p14). We have designed a real-time quantitative PCR (QPCR) application to study homozygous deletion (HD) of CDKN2A/ARF in 186 urinary bladder can...
Future generation wireless networks will demand more intelligent and adaptive handover decision mechanisms to fulfil users’ expectations in terms of seamless mobility over extensive area, min imum price, high data rate, adequate QoS provision and so on. For such a demanding networking environment the handover decision system (HDS) need to be highly intelligent. Fuzzy logic appears to be one of ...
By applying a hexagon-diamond search (HDS) method to an ultrasound image, the path of an object is able to be monitored by extracting images into macro-blocks, thereby achieving image redundancy is reduced from one frame to another, and also ascertaining the motion vector within the parameters searched. The HDS algorithm uses six search points to form the six sides of the hexagon pattern, a cen...
Ketoacyl reductases (KRs), hydroxyacyl dehydratases (HDs) and enoyl reductases (ERs) are part of the fatty acid and polyketide synthesis cycles. Their reverse reactions, catalyzed by acyl dehydrogenases (equivalent to ERs), enoyl hydratases (equivalent to HDs) and hydroxyacyl dehydrogenases (equivalent to KRs), are part of fatty acid degradation by β-oxidation. These enzymes have been classifie...
In this study, we propose an effective data-decoding method for holographic data storage (HDS) by combining convolutional neural network (CNN) and spatially coupled low-density parity-check (SC-LDPC) code. The trained CNN provides output class probabilities accurately demodulates the reproduced from HDS. We focus on these probabilities, wherein only untrainable noise components such as white Ga...
difference set, Hadamard A (u,k,A) difference set is a k-element subset D of a group G of order u for which the multiset {dldl2: dl,d2 E D, dl =t= d2} contains each nonidentity element of G exactly A times. A Hadamard difference set (HDS) has parameters of the form (u,k, A) = (4N2,2N2_N, N2·N). The Hadamard parameters provide the richest source of known examples of difference sets. The central ...
PREP1 and PBX1 are homeodomain (HD) transcription factors that play crucial roles in embryonic development. Here, we present the first biophysical characterization of a PREP1 HD, and the NMR spectroscopic study of its DNA binding pocket. The data show that residues flanking the HD participate in DNA binding. The kinetic parameters for DNA binding of individual PREP1 and PBX1 HDs, and of their c...
This thesis investigates the problem of obtaining overview information from complex tabular numerical data sets non-visually. Blind and visually impaired people need to access and analyse numerical data, both in education and in professional occupations. Obtaining an overview is a necessary first step in data analysis, for which current non-visual data accessibility methods offer little support...
Local factor analysis (LFA) is regarded as an efficient approach that implements local feature extraction and dimensionality reduction. A further investigation is made on an automatic BYY harmony data smoothing LFA (LFA-HDS) from the Bayesian Ying-Yang (BYY) harmony learning point of view. On the level of regularization, an data smoothing based regularization technique is adapted into this auto...
BACKGROUND The occurrence of numerous cases of interstitial lung disease in children (chILD) every spring in Korea starting in 2006 raised suspicion about a causal relationship with the use of humidifier disinfectants (HDs). The aim of this study was to evaluate the association between HD use and the risk of chILD. METHODS This retrospective, 1∶3 matched case-control study consisted of 16 cas...
