Investigation of Analog Memristor Characteristics for Hardware Synaptic Weight in Multilayer Neural Network

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The systematic design of memristor‐based neural network is provided by analog conductance state parameters to accurately emulate the software‐based high‐resolution weight at discrete device level. The requirement of discrete analog conductance of memristor device is measured as ≈50 states with nonlinearity value of ≈0.142 within the deviation range of ...

Single‐Step Analog In‐Memory Matrix Computation in Three‐Dimensional Circuits

Advanced Intelligent Systems, EarlyView.
A wooden model illustrates a 3D memristive array designed for single‐step kernel convolutions. It shows how two‐dimensional input data are mapped into the 3D array and convolved in parallel with stored kernels. Color‐coded connection points represent programmed memory‐element values, with each color corresponding to a specific kernel weight.

Musculoskeletal Phenotypes of 19 Patients With X‐Linked HNRNPH2‐Related Neurodevelopmental Disorder: A Prospective Case Series

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Detailed clinical phenotypes have been previously reported for 33 individuals with X‐linked HNRNPH2‐related neurodevelopmental disorder. Of these, 75% self‐reported a musculoskeletal abnormality, including hip dysplasia, scoliosis, kyphosis, lordosis, pes planus, arthritis, and missing spinous processes.

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,

The effect of temperature on shuttle glow

Nature, 1986
The glow on ram surfaces of the Space Shuttle has been reported from a series of photographic observations made during several orbiter missions. These measurements have shown that the spectrum of the glow is a continuum, has a spectral peak at 680 nm, and the brightness decreases with altitude.

Effects of stimulus modality on the shuttle activity in rats

Behavioural Brain Research, 2004
Shuttle activity during repeated presentation of irrelevant auditory (white band noise) and visual (darkness) stimuli was studied in 32 male Möll-Wistar rats. The subjects were randomly divided into two groups. In Group ND the auditory stimulus was used in the first habituation session, and the visual stimulus in the second habituation session.

Spin Valve Effect in a Magnetic Nanoelectromechanical Shuttle

Physical Review Letters, 2008
We study spin-dependent shuttle phenomena in a nanoelectromechanical single electron transistor (NEM-SET) with magnetic leads by considering the coupling between the transport of spin-polarized electrons and mechanical oscillations of the nanometer quantum dot. It is shown that there are two different bias-voltage thresholds for the shuttle instability

Distinct Nanostructures from a Molecular Shuttle: Effects of Shuttling Movement on Nanostructural Morphologies

Advanced Functional Materials, 2008
AbstractA solvent driven molecular shuttle that contains a TCBD chromophore and in which the macrocycle can be positioned close to or far from the TCBD unit with a change of solvent is prepared. Several distinct nanostructures are obtained by control of the shuttling movement of the macrocycle: i) in a mixed solvent of CHCl3/n‐C6H14 (1/1, v/v), the ...

Diodelike effect in nanoelectromechanical shuttle devices

Physical Review B, 2008
We have analyzed the effect of bias-voltage polarities on the shuttle instability in an asymmetrically nanoelectromechanical single-electron transistor (NEM-SET) using the Wigner phase space approach. The electric-field-induced shift in oscillation equilibrium position together with the asymmetrical tunneling rate leads to the symmetry breaking of ...

Sulfur Hosts against the Shuttle Effect

Small Methods, 2018
AbstractLithium–sulfur (Li–S) batteries are considered as a substitute for conventional batteries as they are the most promising next‐generation energy‐storage system due to their high energy densities. However, their short cycling life, limited sulfur loading, severe polysulfide shuttling, and low sulfur utilization critically impede grid‐level ...
