The effect of lineup size on eyewitness identification accuracy
Eyewitness identification via lineup procedures is an important and widely used source of evidence in criminal cases. However, the current scientific literature provides inconsistent guidance on a very basic question of lineup procedure: lineup size. Some of the ambiguity in the field may be due to …

Automated mammographic mass shape classification using wavelets and neural networks
… classification system was studied using receiver operating characteristic (ROC) analysis. (Abstract shortened by UMI.).

Psychometric properties of the intolerance of uncertainty : believability scale
… in to a sample characterized by high worriers. Receiver-Operating Characteristic (ROC) analysis showed the IUS-B to be effective in identifying high worriers and may possible be a convenient measure of change in cognition through therapy. Keywords: Intolerance of uncertainty scale, believability …

Methylation analysis and diagnostics of Beckwith-Wiedemann syndrome
… diagnosis. In particular, methylation status analysis at two 11p15.5 imprinting control centres (IC1 and IC2) detects up to 80% of BWS cases. However, this is not without its limitations, especially in the detection of low-level mosaicism.<br/><br/>In order to evaluate the relationship between …

CLASSIFICATION OF PATIENTS WITH PAROTID CANCER USING DYNAMIC CONTRAST AND DIFFUSION EXAMINATIONS WITH RADIOMICS AND MACHINE LEARNING TECHNIQUES
… is to evaluate the role of MRI-based radiomics analysis and machine learning using both DWI with multiples B values and dynamic contrast-enhanced T1-weighted sequences to differentiate pleomorphic adenoma (A), Warthin’s tumor (W) and malignant (M) tumors. Materials and Methods: This …

Evaluation of Artifacts In Experimental Cine 4D Ct Acquisition Methods
… add a systematic uncertainty to the treatment process and limit the accuracy of lung function images derived from CT. We proposed to reduce the motion artifacts in cine 4D CT by using three novel investigational 4D CT acquisition methods: (1) oversampling the data acquired, (2) gating the x-ray …

The identification of biomarker differences between grade I and II meningiomas: Fibulin-2 is a novel biomarker for differentiating grade II from grade I meningiomas
… review with an unbiased global proteomic analysis of four grade I and four grade II primary (meningioma) cell cultures, to identify proteins differentially expressed between both grades. Validation of the significantly differentially expressed proteins was then performed by Western …

Neutrophil gelatinase-associated lipocalin (NGAL) and matrix metalloproteinases (MMPs) as biomarkers of bladder cancer development and progression
… the degradation of extracellular matrix in processes such as angiogenesis, tumour growth, and metastasis. By forming the NGAL/MMP-9 complex, NGAL protects MMP-9 from proteolytic degradation, a fundamental mechanism in controlling the activity of the proteins, and enhances its enzymatic …

Nonuniform Power Changes and Spatial, Temporal and Spectral Diversity in High Gamma Band (>60 Hz) Signals in Human Electrocorticography
… in time-frequency analyses of electrocorticographic: ECoG) signals, we hypothesized that induced high-gamma band: 60-500Hz) power changes are more heterogeneous than currently understood. We quantified this spectral non-uniformity with two different approaches using single-word …

Feasibility Study of Low Dose Chest CT for Initial Evaluation of Blunt Chest Trauma Patient
… 13.4mGy) (79.4% dose reduction). Multiple-reader receiver operating characteristic (ROC) analysis for comparing areas under the ROC curves (AUC) demonstrated that LDCT was comparable to SDCT for evaluation of blunt chest injury (AUC in LDCT : 0.823-1.000, AUC in SDCT : 0.781-1.000, p>0.05). ROC …

Neuropsychological assessment accuracy in diagnosing early-onset Alzheimer’s disease
<p>Early-onset Alzheimer’s disease (EOAD), a progressive neurological condition, is often difficult to diagnose before substantial neuronal damage. Neuropsychological assessments offer a more cost-effective and accessible method for detecting early cognitive decline, yet limited research exists on …

Transcriptome activity of human cytomegalovirus (strain Merlin) in fibroblasts, epithelial cells and astrocytes
… pigmented epithelial (RPE) cells, and human astrocytoma cells (U373Mg). A custom HCMV DNA microarray based on recent re-assessments of HCMV coding potential was designed. The Merlin strain of HCMV was used for these studies because it has been reported to contain the complete set of ORFs, only …
