Energy/Delay Tradeoffs in All-Spin Logic Circuits

IEEE Journal on Exploratory Solid-State Computational Devices and Circuits, 2016
All-spin logic (ASL) is a spin-based candidate for implementing logic in the next generation designs. The energy and the delay of ASL circuits are both inherently related to the geometric parameters of ASL gates, and the careful selection of the ...

Evaluation of Brain Microstructural Alterations in Preschool Autism Spectrum Disorder: A Voxel‐Wise Multimodal MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Autism Spectrum Disorder (ASD) presents with early neurodevelopmental alterations in preschool children, yet comprehensive characterization using multimodal quantitative MRI remains limited in this age group. Purpose To investigate voxel‐wise brain microstructural differences in preschool ASD through integrated analysis of cerebral ...

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Language and Cognitive Development in Bimodal Bilingual Deaf Children in Hearing Families: Three Case Studies

Behavioral Sciences
We investigated aspects of language and cognitive development in three bimodal bilingual deaf children in hearing families. Some previous research finds cognitive delays for deaf children, which may be due to an early lack of access to language input ...

Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Dynamic Margin of Stability During Walking Differs Between End‐Stage Hip, Knee, and Ankle Arthritis

Journal of Orthopaedic Research, EarlyView.
ABSTRACT End‐stage arthritis of the hip, knee, or ankle leads to differential gait adaptations, but the differences in gait stability remain poorly understood. This study examined whether dynamic gait stability differed between patients with end‐stage hip arthritis (HA), knee arthritis (KA) and ankle arthritis (AA), and matched healthy controls (HC ...

Enteral and intravenous supplementation of arginine and citrulline fail to prevent necrotizing enterocolitis in preterm neonatal pigs

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants with a morality rate that approaches 50%. Arginine has been widely studied in the field of clinical nutrition as a supplement for patients experiencing critical illness because it can be metabolized into nitric oxide, an important agent ...
