Impaired vascularity and nerve degeneration are the most important pathophysiological abnormalities of diabetic polyneuropathy (DPN). Therefore, regeneration of both the vascular and nervous systems is required for the treatment of DPN. The neural crest (NC) is a transient embryonic structure in vertebrates that differentiates into a vast range of cells, including peripheral neurons, Schwann ce...
BACKGROUND Although hepatocellular carcinoma (HCC) usually develops in cirrhotic livers, a minority of cases occur in noncirrhotic livers (NCLs). We investigated etiology, clinicopathological features, and occult hepatitis B virus (HBV) infection (OBI) in patients with NCL HCC in an HBV-endemic area. METHODS A total of 710 patients who underwent resection or transplantation for HCC at the Nat...
The neuronal ceroid lipofuscinoses (NCLs) are the commonest neurodegenerative disorders of children. The aims of this study were to determine the incidence of NCL in Newfoundland, identify the causative genes, and analyze the relationship between phenotype and genotype. Patients with NCL diagnosed between 1960 and 2005 were ascertained through the provincial genetics and pediatric neurology cli...
Since the NULL Convention Logic (NCL) paradigm is delay-insensitive, NCL combinational circuits cannot be partitioned indiscriminately when pipelining, as can clocked circuits. Instead, these circuits must be partitioned into stages, such that each stage is inputcomplete with respect to all of its inputs and delayinsensitivity is maintained. Therefore the selected architecture for an NCL circui...
Most behavior is composed of action sequences. Pigeons were often used as a model to study sequence learning and execution. Yet, virtually nothing is known about the neural structures underlying sequential behavior in pigeons. We therefore applied a serial reaction time task (SRTT) that is commonly used to investigate sequential behavior. During task performance either the nidopallium caudolate...
ترکیب طبقه بند ها رویکردی است جهت بهبود عملکرد طبقه بندی خصوصاً برای مسایل پیچیده ای از قبیل مسایلی که محدودیت تعداد الگو، مجموعه ویژگی با بعد بزرگ و کلاس های همپوشان دارند. در روش های ترکیب، ثابت شده است که قاعده تقسیم و غلبه در بسیاری از این وضعیت های پیچیده موثر است. اختلاط خبره ها یکی از شناخته شده ترین روش هاست که بر اساس قاعده تقسیم و غلبه پایه گذاری شده است. در این روش فضای مسأله بین تعد...
The 30 th anniversary of NCL, the New Zealand controlled environment laboratory, was marked on 20 March 2000. This anniversary opens the fourth decade of service by NCL to researchers in New Zealand and internationally. Looking forward into this decade provides the stimulus for this workshop series, focused on current issues in controlled environment (CE) science. The workshop series is designe...
Neuronal ceroid lipofuscinoses (NCLs) are a family of inherited pediatric neurodegenerative disorders, with an incidence of 1:12 500 in the US and Scandinavian countries and 1:100 000 worldwide. The major hallmarks of NCLs include retinal degeneration, death of selective neuronal populations and accumulation of autofluorscent ceroid-lipopigments. The clinical manifestations are generally simila...
This work scrutinizes the implementation and performance analysis of novel self-timed asynchronous logic. These templates are based on a delay-insensitive (DI) logic paradigm known as NULL Convention Logic (NCL) that supports RTZ protocol, includes clock-free operation, dual-rail encoding and monotonic transitions. Potential benefits include inherent robustness, low power, reduced noise ratio, ...
