Investigation of disruption management practices and environmental impact on Malaysian automotive supply chains: a case study approach

Much focus on managing a supply chain in the event of disruption has been on the financial consequences and the service level impact on the customers. The negative impact caused by the disruption could influence a company’s profit and market share. Nonetheless, the importance of the environmental impact consideration in the supply chain disruption management has not been emphasised in the existing literature despite research findings that highlight the impact of some resilient supply chain practices on its environmental sustainability. This paper aims to assess the relationship between supply chain mitigation and recovery practices and its environmental impact. To achieve this objective, a case study was employed where semi-structured interviews were conducted at selected automotive companies in Malaysia. The results show that most disruption mitigation and recovery practices of a supply chain have a medium impact on its environmental performance. In particular, the production process during supply disruption recovery has the highest influence on environmental performance in the form of waste generation and use of energy. The results of this study can be used by supply chain managers to focus their efforts in the right direction in order to achieve cost objectives, service levels and environmental goals during the management of disruptions

SHREC 2011: robust feature detection and description benchmark

Feature-based approaches have recently become very popular in computer vision and image analysis applications, and are becoming a promising direction in shape retrieval. SHREC'11 robust feature detection and description benchmark simulates the feature detection and description stages of feature-based shape retrieval algorithms. The benchmark tests the performance of shape feature detectors and descriptors under a wide variety of transformations. The benchmark allows evaluating how algorithms cope with certain classes of transformations and strength of the transformations that can be dealt with. The present paper is a report of the SHREC'11 robust feature detection and description benchmark results.Comment: This is a full version of the SHREC'11 report published in 3DO

Ubiquitination of α-integrin cytoplasmic tails

Recent findings have shown that ubiquitination is involved in regulating several proteins required for cell adhesion and migration. We showed that α5 integrin is ubiquitinated at its cytoplasmic lysines in response to fibronectin binding, and that this is required for its sorting to lysosomes together with fibronectin. Here we speculate whether other α integrin tails may also be ubiquitinated, and discuss the significance of ubiquitin linkages in the regulation of cell adhesion and migration

HLA-DR antigen and bax protein expression in patients with primary non-Hodgkin's gastric lymphoma

Primary gastric lymphoma represents a rare gastrointestinal malignancy with an unclear prognosis. The aim of this study was to determine the prognostic significance of HLA-DR antigen and bax expression in patients with primary non-Hodgkin’s gastric lymphoma. We immunohistochemically studied bax protein and HLA-DR antigen expression in 36 B-cell, MALT-type primary gastric lymphoma patients diagnosed and treated in our department from 1990 to 1995. Ten non-malignant gastric tissue specimens were used as benign controls. Clinicopathological and survival data were correlated with the staining results. HLA-DR antigen expression was observed in 33 gastric lymphoma patients (91.7%). Positive bax staining was found in 24 gastric lymphomas (66.7%) and in none of the benign cases studied. In the univariate analysis, those gastric lymphoma patients who expressed HLA-DR antigen in more than 15% of their tumor cells, presented a significantly improved 5-year survival rate (75% vs. 37.5%, p = 0.04). Furthermore, gastric lymphoma patients who were bax(+)/HLA-DR(+) had a statistically better overall survival compared to those who were bax(-)/HLA-DR(-) (82.4% vs. 25%, p = 0.01). HLA-DR antigen expression was associated with a favorable clinical outcome. Its expression improved the predictive value of bax protein expression in non-Hodgkin’s gastric lymphoma patients. The combined use of these markers permits the identification of a high-risk group of patients that may benefit from a more aggressive therapeutic approach

Multilevel active registration for kinect human body scans: from low quality to high quality

Registration of 3D human body has been a challenging research topic for over decades. Most of the traditional human body registration methods require manual assistance, or other auxiliary information such as texture and markers. The majority of these methods are tailored for high-quality scans from expensive scanners. Following the introduction of the low-quality scans from cost-effective devices such as Kinect, the 3D data capturing of human body becomes more convenient and easier. However, due to the inevitable holes, noises and outliers in the low-quality scan, the registration of human body becomes even more challenging. To address this problem, we propose a fully automatic active registration method which deforms a high-resolution template mesh to match the low-quality human body scans. Our registration method operates on two levels of statistical shape models: (1) the first level is a holistic body shape model that defines the basic figure of human; (2) the second level includes a set of shape models for every body part, aiming at capturing more body details. Our fitting procedure follows a coarse-to-fine approach that is robust and efficient. Experiments show that our method is comparable with the state-of-the-art methods.Comment: 14 pages, the Journal of Multimedia System
