We present ABCD-NL, a technique that approximates non-linear analog circuits using purely Boolean models, to high accuracy. Given an analog/mixed-signal (AMS) system (e.g., a SPICE netlist), ABCD-NL produces a Boolean circuit representation (e.g., an And Inverter Graph, Finite State Machine, or Binary Decision Diagram) that captures the I/O behaviour of the given system, to near-SPICE accuracy,...

cerebrovascular attack (cva) and transient ischemic attack (tia) are major causes of emergency department visits around the globe. a significant number of these patients may experience repeat attacks if left untreated. several risk stratifying scoring systems have been developed in recent years to point out the high risk patients. abcd 2 is based on age, blood pressure, clinical status, diabete...

We report a randomized, double-blind, multicenter trial in which amphotericin B colloidal dispersion (ABCD [Amphotec]; 6 mg/kg/day) was compared with amphotericin B (AmB; 1.0-1.5 mg/kg/day) for the treatment of invasive aspergillosis in 174 patients. For evaluable patients in the ABCD and AmB treatment groups, respective rates of therapeutic response (52% vs. 51%; P=1.0), mortality (36% vs. 45%...

The ABCD twin study will elucidate the genetic and environmental contributions to a wide range of mental and physical health outcomes in children, including substance use, brain and behavioral development, and their interrelationship. Comparisons within and between monozygotic and dizygotic twin pairs, further powered by multiple assessments, provide information about genetic and environmental ...

The dermatoscopic ABCD rule has been suggested to improve diagnostic performance regarding cutaneous malignant melanoma. Using this rule, a total dermatoscopy score is calculated from the presence of various dermatoscopic elements. A total dermatoscopy score above 4.75 signifies possible and 5.45 probable melanoma. We compared the diagnostic accuracy of dermatoscopy with and without the use of ...

BACKGROUND AND PURPOSE The National Institute for Clinical Excellence (NICE) recommends that patients with a transient ischemic attack and ABCD(2) score > or =4 and those with >2 transient ischemic attacks within 1 week be admitted for urgent complete etiologic evaluation within 24 hours and that those with an ABCD(2) score <4 be evaluated less urgently within 1 week. METHODS Using data from ...

Background and Purpose—The National Institute for Clinical Excellence (NICE) recommends that patients with a transient ischemic attack and ABCD score 4 and those with 2 transient ischemic attacks within 1 week be admitted for urgent complete etiologic evaluation within 24 hours and that those with an ABCD score 4 be evaluated less urgently within 1 week. Methods—Using data from 1176 patients wi...

BACKGROUND AND PURPOSE It is unclear whether patients with transient ischemic attack with an ABCD(2) score <4 can be safely evaluated within the following week as recommended by some national guidelines rather than in emergency. METHODS A total of 1679 patients in the SOS-TIA prospective cohort had a definite or possible transient ischemic attack and had complete information on ABCD(2) score ...

Background and Purpose—We sought to determine if the ABCD score, typically used for risk stratification, could predict having a positive diagnostic test in patients evaluated acutely for transient ischemic attack. Methods—We performed a retrospective cohort study for patients admitted from our emergency department with a new diagnosis of transient ischemic attack confirmed by a neurologist. ABC...
