Characteristics of periodically loaded CPW structures [PDF]

open access: yes, 1998
A capacitively loaded coplanar waveguide (CPW) resonator has been studied. It has been shown that the proposed resonator can be used to achieve a slow-wave effect without occupying extra surface area and it has a good performance as compared with the ...

Fifteen-year population attributable fractions and causal pies of risk factors for newly developed hepatocellular carcinomas in 11,801 men in Taiwan.

open access: yesPLoS ONE, 2012
Development of hepatocellular carcinoma (HCC) is a multi-factorial process. Chronic infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are important risk factors of HCC. Host factors, such as alcohol drinking, may also play a role.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Performance enhancement of millimetre-wave resonators using elevated CPW

open access: yes, 2009
A method for overcoming the poor performance exhibited by coplanar waveguide (CPW) short circuit stubs at sub-millimetre-wave frequencies is presented. The method uses a CPW with ground and signal traces elevated 5 mm above a 625 mm-thick GaAs substrate ...

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...

Design of controlled RF switch for beam steering antenna array

open access: yes, 2008
YesA printed dipole antenna integrated with a duplex RF switch used for mobile base station antenna beam steering is presented. A coplanar waveguide to coplanar strip transition was adopted to feed the printed dipole.

Reduced-Dimension Wiener Filter Based on Perpendicular Partition

open access: yesIEEE Access, 2019
This paper addresses the reduced-dimension Wiener filter based on perpendicular partition. Two algorithms, i.e., cyclic per-weight (CPW) and batch CPW (BCPW) are presented, which can efficiently perform reduced-dimension adaptive beamforming.

Statistical Characteristics of Environments of Precipitating Mesoscale Convective Systems During the Pre‐Summer Season Over South China

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Mesoscale convective systems (MCSs) are known to induce heavy rainfall and pose significant weather hazards in tropical and mid‐latitude regions. Understanding the environmental conditions of MCSs is essential for improving model simulations and operational precipitation forecasts.
