Fundamental problems in the analysis of functional and structural imaging data include transport, boundary identification (including manual tracing, edge detection, tissue segmentation), volume estimation, three-dimensional reconstruction display, surface rendering, shape analysis, image overlay. These require that research investigators have access to suitable methods implemented on a set software programs, order conduct neuroimaging research. The authors describe group programs designed...

Purpose: To improve the reliability, accuracy, and computational efficiency of tissue classification with multispectral sequences [T1, T2, proton density (PD)], we developed an automated method for identifying training classes to be used in a discriminant function analysis. We compared it supervised operator-dependent method, evaluating its reliability validity. also fuzzy (continuous) correct partial voluming. Method: Images were obtained on 1.5 T GE Signa MR scanner using three pulse that...

Several shortcomings of current Parkinson's disease (PD) models limit progress in identification environmental contributions to pathogenesis. The conditionally immortalized cell line LUHMES promises make human dopaminergic neuronal cultures more easily available, but these cells are difficult culture for extended periods time. We overcame this problem by culturing them 3D with minor medium modifications. aggregates allowed penetration small molecules and sufficient oxygen nutrient supply...

This work considers the conceptualization and design of a 4 Rs framework for creating general purpose, modular Digital Twin. The Rs, correspond to different phases Twin implementation, namely Representation, Replication, Reality, Relational. Representation is about understanding physical system, its behavior, actions, components, relationships describing significant features identified use case as data algorithms. Replication duplicates chosen components/variables in virtual environment from...

Summary The aim of the study was to examine efficacy and safety temazepam on nocturnal oxygenation next‐day performance at altitude. A double‐blind, randomized, cross‐over trial performed in Thirty‐three healthy volunteers. Volunteers took 10 mg placebo random order two successive nights soon after arrival 5000 m, following a 17‐day trek from 410 m. Overnight SaO 2 body movements, reaction time, maintenance wakefulness cognition were assessed. Compared with placebo, resulted reduction...

Purpose Few companies have had the success that Toyota Motor Corporation has experienced over past 70 years. Many give credit for Toyota's to company's famous Production System. Companies outside of tried implement versions system as Lean production; however, few Toyota, and none sustained success. In 2001, released a publication entitled The Way 2001 set globalized standards culture drives Design/methodology/approach This research examines effect on implementation production Toyota. A...

Digital Twin (DT) is a concept of growing interest, driven by the technological advancements related to Industry 4.0. DT combines innovative technologies create virtual model replicating physical system and allowing bi-directional data flow. However, use DTs in support decision-making, it essential have trust all components throughout its development. Verification Validation (V&V) traditionally been employed assess models' credibility, providing venue for development trust. Therefore, V&V...

Abstract In the connected age of model‐based enterprise and systems engineering (MBSE), new tools are needed to move from a functional, document‐centric, hierarchical view data information individual units or element level view. Data mapping analysis (DEMA) is technology‐agnostic analytical methodology that combines traditional functional techniques, elicitation practices, novel techniques provide holistic system's flows at (data level). this research, DEMA was utilized enable an enhanced...

Compression socks have become a popular recovery aid for distance running athletes. Although some physiological markers been shown to be influenced by wearing these garments, scant evidence exists on their effects functional recovery. This research aims shed light onto whether the of compression 48 hours after marathon can improve recovery, as measured timed treadmill test exhaustion 14 days following running.

:In his 1997 Harvard Business Review article, Fisher suggests that supply chain improvement efforts have not produced expected results due to misalignment of products with strategies. His framework appeals logically and researchers rapidly moved into modifications Fisher's premise. A critical missing component, however, is a quantitative analysis the benefits proper classification alignment appropriate strategies optimize performance. Quantifiable proof can strengthen validity initial...

The progressive decline of the nervous system, including protein aggregate formation, reflects subtle dysregulation multiple functional pathways. Our previous work has shown intermittent fasting (IF) enhances longevity, maintains adult behaviors and reduces aggregates, in part, by promoting autophagic function aging Drosophila brain. To clarify impact that IF-treatment upon aging, we used high throughput RNA-sequencing technology to examine changing transcriptome tissues. Principle component...
