Long‐Term Neurologic Exam Findings in People Diagnosed and Treated During Acute HIV Infection

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Evaluate clinical and laboratory correlates of abnormal neurologic exam findings after acute HIV infection (AHI). Methods Participants from the RV254/SEARCH 010 cohort in Bangkok underwent standardized neurologic examinations at Weeks 0 (AHI), 12, 96, and 288 following antiretroviral therapy (ART).

Ground-Borne Vibration Prediction in a Metro Depot Using Hybrid Train-Soil-Pile-Structure Interactions

open access: yesVibration
Train-induced ground vibrations can propagate into pile foundations, potentially causing undesirable vibration in nearby buildings, laboratories housing vibration-sensitive equipment, and manufacturing facilities for high-precision processes.

Multimodal Optoelectronic Synapses for Neuromorphic Intelligence: Coupling Light, Electrical, Thermal, and Beyond

open access: yesAdvanced Functional Materials, EarlyView.
This review revisits optoelectronic neuromorphic devices that extend from unimodal sensing toward multimodal perception. Five types of stimuli‐to‐output information flow that are classified based on the device roles within the system and applications are summarized and discussed.

Investigation of the hysteresis behavior of a convex column brace based on buckling mode transition mechanism

open access: yesAdvances in Mechanical Engineering, 2019
Brace structures with nonlinear stiffness are attractive in vibration mitigation. A new brace consisting of a novel convex column, which is characterized by the addition of a bulge structure compared to a column with constant cross-section, is proposed ...

Vibration Condition Monitoring of Brickwork Columns

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 1997
This paper describes the development of a condition monitoring and analysis technique, based on the pulse echo and impulse excitation method, for brickwork structures. The method is applied to structural brickwork columns with different brick and mortar strength combinations.

Vibrating Air Column of High Frequency [PDF]

open access: yesNature, 1929
IN the course of some experiments recently carried out in these laboratories, a curious series of annular markings was observed in a glass tube through which air, carrying water-vapour and powered charcoal, was passing under diminished pressure. The accompanying photograph (Fig.

Dynamic analysis of high static low dynamic stiffness vibration isolation mounts [PDF]

open access: yes, 2013
The high static low dynamic stiffness (HSLDS) concept is a design strategy for an anti-vibration mount that seeks to increase isolation by lowering the natural frequency of the mount, whilst maintaining the same static load bearing capacity.
