A Neuromorphic Simulation Framework for Indium‐Gallium‐Zinc‐Oxide Charge‐Trap Synaptic Transistors: From Device Modeling to System Simulation

Advanced Intelligent Systems, EarlyView.
This work presents a comprehensive framework bridging device fabrication, modeling, and system‐level simulation for an indium‐gallium‐zinc‐oxide (IGZO) charge‐trap synaptic transistor‐based neuromorphic system. By developing a precise SPICE model derived from fabricated IGZO synaptic transistors, the study incorporates parasitic RC loads into array ...

The Protection of RC Columns by Bio-Inspired Honeycomb Column Thin-Walled Structure (BHTS) Under Impact Load

Biomimetics
The bio-inspired honeycomb column thin-walled structure (BHTS) is inspired by the biological structure of beetle elytra and designed as a lightweight buffer interlayer to prevent damage to the reinforced concrete bridge pier (RCBP) under the overload ...

Civilian Occupational Exposure to Vapors, Gas, Dust, or Fumes and Respiratory Health Among United States Military Veterans

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background We investigated associations of self‐reported and job exposure matrix (JEM) assigned civilian occupational exposure to vapors, gas, dust, or fumes (VGDF) with respiratory symptoms among previously deployed US Veterans. Methods An interviewer‐administered questionnaire ascertained self‐reported civilian occupational VGDF exposure.

Mechanical Performance of Prefabricated Monolithic Composite Columns with Reinforced ECC Precast Shell

Buildings
To enhance the mechanical properties of a precast monolithic column, the ECC material was made into a prefabricated shell with reinforced bars. Post-cast concrete was poured into the precast parts to form the reinforced ECC precast monolithic composite ...

Joint Contribution to the Deformation of RC Beam-Column Sub-Assemblies [PDF]

, 2004
In this paper, the contribution of joint shear deformation to the overall storey-drift of reinforced concrete (RC) beam-column sub-assemblies is investigated experimentally. Two lightly reinforced beamcolumn sub-assemblies, one without any hoops inside

A realistic full CFRP retrofit of RC beam-column joints compared to seismically designed specimen [PDF]

, 2017
The brittle collapse of reinforced concrete (RC) structures built before the introduction of detailed seismic design codes (pre- 1970’s) in recent earthquakes, has underlined the need for significant upgrades to the existing RC building stock.

X-ray Eclipses of Active Galactic Nuclei

, 2017
X-ray variation is a ubiquitous feature of active galactic nuclei (AGNs), however, its origin is not well understood. In this paper, we show that the X-ray flux variations in some AGNs, and correspondingly the power spectral densities (PSDs) of the ...

Non-Slender RC Column Limits

, 2003
Structural frame systems may be analyzed and designed based on forces from conventional first order theory when second order effects of axial forces on displacements in the compression members of the system are negligible. This is often the case. Slenderness limits at which this is the case are studied in this paper.
