In this paper, a statistical distribution is presented that possesses the ability to describe failure rates exhibiting both monotonic and non-monotonic behaviors, bathtub curve, which represents performance of device in reliability engineering. The proposed based on sum hazard functions Chen Perks distribution, thus presenting Chen–Perks (CPD). Statistical properties CPD focused engineering are...

Color can enhance the perception of relevant stimuli by increasing their salience and guiding visual search towards that match a task-relevant color. Using Continuous Flash Suppression (CFS), current study investigated whether color facilitates discrimination targets are difficult to perceive due interocular suppression. Gabor patterns two or four cycles per degree (cpd) were shown as non-domin...

BACKGROUND Previous studies with adult smokers have shown an association between number of cigarettes smoked per day (CPD) and levels of biomarkers of exposure to the tobacco-specific lung carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). This study compared carcinogen and nicotine exposure in adolescent and adult smokers across categories of CPD. METHOD Baseline smoking histor...

BACKGROUND Malnutrition is associated with an increased risk of cardiovascular death and may cause protein-energy wasting in individuals with chronic kidney disease. A previous study demonstrated that blood cadmium levels (BCLs) were associated with malnutrition in maintenance hemodialysis (MHD) patients. However, the correlation between cadmium exposure and malnutrition remains unclear in chro...

Dual specificity phosphatases (DSP) play an important role in control of the cell cycle and signal transduction. We have synthesized a new class of DSP inhibitors. Cpd 5 or [2-(2-mercaptoethanol)-3-methyl-1,4-naphthoquinone] is one of the most potent of these. It inhibits DSPs of cells in culture and induces tyrosine phosphorylation of various DSP substrates, including the Cdc25 target Cdks and...

BACKGROUND To systematically evaluate the visual performance of aspheric AcrySof IQ and spherical AcrySof Natural intraocular lens (IOL) after cataract surgery. METHODOLOGY/PRINCIPAL FINDINGS Potential randomized controlled trials (RCTs) that involved implanting AcrySof IQ and AcrySof Natural were searched from PubMed, Web of science, EMBASE, Chinese Science and Technology Periodicals Databas...

Introduction As a part of the NHS modernisation agenda to ensure high quality clinical care, podiatrists are required to demonstrate evidence of continuing professional development to maintain registration. This study aimed to investigate the experiences of podiatrists in response to the CPD process. It explored the effectiveness of the portfolio in recording CPD, resource as a limiting factor ...

One of the tasks in the BioCreative V challenge, the CHEMDNERPatent task, includes three subtasks: CEMP, CPD, and GPRO. We participated in the CEMP and CPD subtasks, and developed a system on the basis of selected open-source NLP, machine learning toolkits. In our system, the CEMP subtask is regarded as a sequence labeling problem, and the CPD subtask is regarded as a text classification problem.

OBJECTIVES To report changes in perceived visual functioning after surgery for symptomatic cataract with preoperative corrected distance visual acuity [CDVA] of 0.4 logMAR or better (Snellen equivalent, 20/50) and to investigate the relationship between any observed changes and preoperative physical characteristics and psychophysical consequences of the lens opacity and any changes in psychophy...

OBJECTIVE This study was undertaken to develop an easily usable integrated formula for predicting the probability of cephalopelvic disproportion/failure to progress (CPD) and cesarean delivery (CS) as a function of demographic factors in a middle-class private practice, and to evaluate risk factors for CS in a low-risk primiparous population. METHODS We studied 3355 primiparous women who deli...
