Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Comparison of Two Auto-Contouring Systems for Head and Neck Organs at Risk to Institutional Reference Standard in Radiotherapy Planning

open access: yesApplied Sciences
Background: Manually contouring the organs at risk (OARs) is a time-consuming process with significant variability. Multiple commercial options are available to streamline this process by utilizing artificial intelligence.

Finsler Active Contours [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2008
In this paper, we propose an image segmentation technique based on augmenting the conformal (or geodesic) active contour framework with directional information. In the isotropic case, the Euclidean metric is locally multiplied by a scalar conformal factor based on image information such that the weighted length of curves lying on points of interest ...

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.

Implementing user‐defined atlas‐based auto‐segmentation for a large multi‐centre organisation: the Australian Experience

open access: yesJournal of Medical Radiation Sciences, 2019
Introduction Contouring has become an increasingly important aspect of radiation therapy due to inverse planning, and yet is extremely time‐consuming. To improve contouring efficiency and reduce potential inter‐observer variation, the atlas‐based auto ...

Force control for automatic cashew shelling considering size variance

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
Vietnam has the world's largest market share of cashew nuts, and hence a large number of workers are involved in the cashew processing industry. A shelling operation is necessary to acquire a kernel (edible portion) of a cashew.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Contour adaptation

open access: yesJournal of Vision, 2013
It is known that adaptation to a disk that flickers between black and white at 3-8 Hz on a gray surround renders invisible a congruent gray test disk viewed afterwards. This is contrast adaptation. We now report that adapting simply to the flickering circular outline of the disk can have the same effect.
