OBJECTIVE Compulsive hoarding is a debilitating problem that is often associated with obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder. However, the precise nosology of compulsive hoarding has yet to be determined. METHOD Participants were 25 patients with severe compulsive hoarding with OCD and 27 patients with severe(More)
Traumatic life events and early material deprivation have been identified as potential environmental risk factors for the development of pathological hoarding behavior, but the evidence so far is preliminary and confounded by the presence of comorbid obsessive-compulsive disorder (OCD). This study retrospectively examined the occurrence of(More)
Experiential avoidance can be defined as the tendency to avoid contact with unwanted internal experiences. Current conceptualizations of pathological hoarding appear broadly consistent with an experiential avoidant model. Eighty participants in four groups, namely hoarding disorder (HD) without comorbid obsessive-compulsive disorder (OCD), HD with comorbid(More)
A novel VLSI implementation of the Viterbi algorithm based on a cascade architecture is presented. Survivor sequence memory management is implemented using a new single read pointer traceback technique. The overall design for a 16-qtate, rate 1/2 decoder requires about 26000 transistors and a core area of 8.5 mma in a 1.2 pm two-level metal CMOS technology.(More)
Oesophageal penetration and migration of foreign bodies are fairly rare occurrences. Most reported cases in the literature involve fish bones, which are eventually found in the lateral neck soft tissue or thyroid lobule. We present a case of a migrating fish bone in an elderly female which was found embedded in her right sternocleidomastoid muscle. The fish(More)
This paper explores the effect of logic block architecture on the speed of a field-programmable gate array (FPGA). Four classes of logic block architecture are investigated: NAND gates, multiplexer configurations, lookup tables, and wide-input AND-OR gates. An experimental approach is taken, in which each of a set of benchmark logic circuits is synthesized(More)
Objective: Compulsive hoarding remains a significant public health issue, with many sufferers failing to acknowledge the problem. A number of methodological approaches have been utilised to explore and explain this complex phenomenon, though few have made use of contemporary visually inspired approaches. In an earlier study, it was found that visual methods(More)
