Amyotrophic lateral sclerosis (ALS) is a paralytic and usually fatal disorder caused by motor-neuron degeneration in the brain and spinal cord. Most cases of ALS are sporadic but about 5-10% are familial. Mutations in superoxide dismutase 1 (SOD1), TAR DNA-binding protein (TARDBP, also known as TDP43) and fused in sarcoma (FUS, also known as translocated in(More)
BACKGROUND The SQSTM1 gene encodes p62, a major pathologic protein involved in neurodegeneration. OBJECTIVE To examine whether SQSTM1 mutations contribute to familial and sporadic amyotrophic lateral sclerosis (ALS). DESIGN Case-control study. SETTING Academic research. Patients  A cohort of 546 patients with familial (n = 340) or sporadic (n = 206)(More)
Mining concept drifting data streams is a defining challenge for data mining research. Recent years have seen a large body of work on detecting changes and building prediction models from stream data, with a vague understanding on the types of the concept drifting and the impact of different types of concept drifting on the mining algorithms. In this paper,(More)
BACKGROUND Mutations in optineurin have recently been linked to amyotrophic lateral sclerosis (ALS). OBJECTIVE To determine whether optineurin-positive skeinlike inclusions are a common pathologic feature in ALS, including SOD1 -linked ALS. DESIGN Clinical case series. SETTING Academic referral center. SUBJECTS We analyzed spinal cord sections from(More)
Despite the rapid development, the field of data mining and knowledge discovery (DMKD) is still vaguely defined and lack of integrated descriptions. This situation causes difficulties in teaching, learning, research, and application. This paper surveys a large collection of DMKD literature to provide a comprehensive picture of current DMKD research and(More)
Chromosome fragmentation is a hallmark of apoptosis, conserved in diverse organisms. In mammals, caspases activate apoptotic chromosome fragmentation by cleaving and inactivating an apoptotic nuclease inhibitor. We report that inactivation of the Caenorhabditis elegans dcr-1 gene, which encodes the Dicer ribonuclease important for processing of small RNAs,(More)
Mutations in TRPV4 have been linked to three distinct axonal neuropathies. However, the pathogenic mechanism underlying these disorders remains unclear. Both gain and loss of calcium channel activity of the mutant TRPV4 have been suggested. Here, we show that the three previously reported TRPV4 mutant channels have a physiological localization and display(More)
Video shot boundary detection (SBD) is the first and essential step for content-based video management and structural analysis. Great efforts have been paid to develop SBD algorithms for years. However, the high computational cost in the SBD becomes a block for further applications such as video indexing, browsing, retrieval, and representation. Motivated(More)
