The CMM model of belt-CVT dynamics

open access: yes, 2007
We present an experimental investigation of the pushing V-belt CVT dynamics with the aim of comparing the experimental data with the theoretical predictions of the Carbone, Mangialardi, Mantriota (CMM) model(1).

Efficient Environment Representation for Mobile Robot Path Planning using CVT-PRM with Halton Sampling

open access: yes, 2018
A centroidal Voronoi tessellation-based probabilistic roadmap (CVT-PRM) and its construction method for mobile robot path planning are introduced. The CVT-PRM efficiently encoded the entire unoccupied region of the environment by autonomously rearranging

Van der Waals ferroelectric semiconductor tunnel junction with ultra‐low switching voltage

open access: yesInfoMat, EarlyView.
Ferroelectric tunnel junctions are promising building blocks for energy‐efficient memory and brain‐inspired computing, but their practical use is limited by the relatively high voltages required for operation. Here, we develop an all‐two‐dimensional ferroelectric tunnel junction based on AgBiP2Se6 that enables reliable memory operation below 0.2 V and ...

Imaging and clinical outcomes of COVID-19- vs. non-COVID-19-related cerebral venous thrombosis

open access: yesFrontiers in Stroke
BackgroundCerebral venous thrombosis (CVT) is a rare but serious subtype of stroke. Several studies have reported an increased incidence of CVT after either COVID-19 (CoV19) infection or vaccination; however, data on clinical characteristics, the ...

Machine Learning‐Assisted Optimization for Dynamic Supply Network Design in the Additive Manufacturing Platform

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Distributed manufacturing enabled by additive manufacturing (AM) allows supply chains to rapidly adapt to changing market conditions through flexible facility relocation and capacity adjustment. However, existing studies largely overlook the logistical aspects of AM‐based supply chains and typically treat facility location and logistics ...

Metal‐Iodide‐Mediated CVT Growth of Form V Red Phosphorus Wires

open access: yesSmall, EarlyView.
AgI‐mediated chemical vapor transport enables on‐substrate growth of high‐aspect‐ratio red‐phosphorus wire‐like nanostructures, including multiple individual wires indexed to single‐crystalline Form V by transmission electron microscopy/selected area electron diffraction (TEM/SAED).

CVT in the Peripartum Period: A Diagnostic Dilemma

open access: yesCase Reports in Obstetrics and Gynecology, 2020
Women in the peripartum period can develop headache with a variety of etiologies that require a multidisciplinary approach if unresponsive to treatment (Stella et al. 2007). Neuroimaging needs to be undertaken even occasionally in the absence of focal neurologic signs to rule out life‐threatening causes of headache. We present the case of a 23‐year‐old

A Multi‐Sequence Adversarial Fusion U‐Net for Brain Tumor Image Segmentation

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
In the field of brain tumor image segmentation, in order to avoid the impact of insufficient number of training samples, the method of fusing multi‐modal MRI information before segmentation is widely used. However, when fusing different modal features, existing methods only add fixed weights to the features of each modality, resulting in insufficient ...
