Chronic obstructive pulmonary disease (COPD) has seriously impacted the health of individuals and populations. In this study, proton nuclear magnetic resonance ((1)H NMR)-based metabonomics combined with multivariate pattern recognition analysis was applied to investigate the metabolic signatures of patients with COPD. Serum and urine samples were collected(More)
Diffusion-weighted MRI (DWI) has been proposed as a method to evaluate the integrity of white matter tracts in the spinal cord. The integrity of the spinal cord reflects the exact stage of traumatic injury. The purpose of this study was to evaluate the diagnostic value of DWI in SCIWORA in the thoracic spine. A total of five patients with thoracic SCIWORA(More)
In this paper, a new 3D-object-recognition method for robotic assembly workcells is presented. The proposed method is focused on two basic concepts , namely active vision and object pre-conditioning. The paper will briefly present the main aspects of the proposed system. 1. The Proposed Recognition Method [l] Herein, it is proposed to model an object using(More)
The objectives of this epidemiological study were to evaluate the prevalence of farmer’s lung disease (FLD) and to explore the potential risk factors for FLD among Chinese greenhouse farmers. A total of 835 plastic film greenhouses, including 5,880 active farmers who engaged in crop cultivation or poultry farming, were randomly selected from the rural(More)
Despite decades of extensive studies, the morbidity and mortality for acute lung injury/acute respiratory distress syndrome (ALI/ARDS) remained high. Particularly, biomarkers essential for its early diagnosis and prognosis are lacking. Recent studies suggest that alveolar macrophages (AMs) at the exudative phase of ALI/ARDS initiate, amplify and perpetuate(More)
For a finite abelian group G and a positive integer k, let s k (G) denote the smallest integer ℓ ∈ N such that any sequence S of elements of G of length |S| ≥ ℓ has a zero-sum subsequence with length k. The celebrated Erd˝ os-Ginzburg-Ziv theorem determines s n (C n) = 2n − 1 for cyclic groups C n , while Reiher showed in 2007 that s n (C 2 n) = 4n − 3. In(More)
A novel active-vision system for 3-D object recognition was developed. The vision system combines object pre-marking and active sensing. Therein, an object is modeled by a few of its 2-D perspective (standard) views, each with a corresponding viewing axis defined by a marker placed on the object. The operation of the active-vision system is characterized by(More)
