Extracting Semantics of Individual Places from Movement Data by Analyzing Temporal Patterns of Visits [PDF]

open access: yes, 2013
Data reflecting movements of people, such as GPS or GSM tracks, can be a source of information about mobility behaviors and activities of people. Such information is required for various kinds of spatial planning in the public and business sectors ...

A Wireless Safety System for Detecting Gas Leakage in Air Conditioner [PDF]

open access: yesE3S Web of Conferences
— In this paper, we’ll keep an eye on the air conditioner’s gas leaking. Frequently, a minor gas leak can cause a gas concentration to grow up explosively over time.

Predicted predissociation linewidths in the Schumann-Runge bands of O2 compared with recent high resolution measurements [PDF]

open access: yes, 2001
The fine-structure predissociation linewidths for the Schumann-Runge bands were evaluated by the model of Julienne and krauss. The parameters were adjusted and modified to account for the fine-structure data for rotational states of vibrational levels v ...

Generalized Spatial Modulation in Large-Scale Multiuser MIMO Systems

open access: yes, 2015
Generalized spatial modulation (GSM) uses $n_t$ transmit antenna elements but fewer transmit radio frequency (RF) chains, $n_{rf}$. Spatial modulation (SM) and spatial multiplexing are special cases of GSM with $n_{rf}=1$ and $n_{rf}=n_t$, respectively ...

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Eavesdropping on GSM: state-of-affairs [PDF]

open access: yes, 2010
In the almost 20 years since GSM was deployed several security problems have been found, both in the protocols and in the - originally secret - cryptography.

Generalized Spatial Modulation in Indoor Wireless Visible Light Communication

open access: yes, 2015
In this paper, we investigate the performance of generalized spatial modulation (GSM) in indoor wireless visible light communication (VLC) systems. GSM uses $N_t$ light emitting diodes (LED), but activates only $N_a$ of them at a given time.

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

open access: yesAdvanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems
