The internet, E-commerce and older people: an actor-network approach to researching reasons for adoption and use [PDF]

open access: yes, 2003
Many older people are discovering the Internet, and some are also making good use of electronic commerce and all that goes with it. Others, however, are not adopting these technologies.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Consecutive Leakage-Resilient and Updatable Lossy Trapdoor Functions and Application in Sensitive Big-Data Environments

open access: yesIEEE Access, 2018
Lossy trapdoor functions (LTFs) are very useful tools in constructing complex cryptographic primitives in a black-box manner, such as injective trapdoor functions, collision-resistant hashes, CCA secure public-key encryption, and so on.

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

Technology Policy, Gender, and Cyberspace [PDF]

open access: yes, 1997
Event based sampling occurs when the time instants are measured everytime the amplitude passes certain pre-defined levels. This is in contrast with classical signal processing where the amplitude is measured at regular time intervals.

Lessons Learned: Quality Analysis of Optical Coherence Tomography in Neuromyelitis Optica

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Optical coherence tomography (OCT)‐derived retina measurements are markers for neuroaxonal visual pathway status. High‐quality OCT scans are essential for reliable measurements, but their acquisition is particularly challenging in eyes with severe visual impairment, as often observed in neuromyelitis optica spectrum disorders ...
