Hybrid Precoder and Combiner Design with Low Resolution Phase Shifters in mmWave MIMO Systems [PDF]

open access: yes, 2017
Millimeter wave (mmWave) communications have been considered as a key technology for next generation cellular systems and Wi-Fi networks because of its advances in providing orders-of-magnitude wider bandwidth than current wireless networks.

Multicohort Validation of Gut Microbiome Signatures for Cholangiocarcinoma Diagnosis and Functional Characterization of Bifidobacterium Pseudocatenulatum

open access: yesAdvanced Science, EarlyView.
This study analyzes gut bacteria in cholangiocarcinoma patients, revealing distinct microbial signatures that enable accurate disease detection. Species‐based diagnostic models achieved over 98% accuracy in identifying cholangiocarcinoma and distinguished it from other liver diseases. The research demonstrates that specific beneficial bacteria suppress

Mesoscale simulations of coastal boundary-layer transitions. Part 1: low-level jets

open access: yesMeteorologische Zeitschrift
The impact of coastal low-level jets (LLJs) should be taken into account in the planning and operating phases of offshore wind farms as these elevated wind maxima introduce additional kinetic energy and vertical wind shear at operational heights of ...

Thermal conditions during heat waves of a mid-European metropolis under consideration of climate change, urban development scenarios and resilience measures for the mid‑21st century

open access: yesMeteorologische Zeitschrift, 2021
In this study we produce two urban development scenarios estimating potential urban sprawl and optimized development concerning building construction, and we simulate their influence on air temperature, surface temperatures and human thermal comfort.

Background Error in WRF Model

open access: yesWSEAS TRANSACTIONS ON ENVIRONMENT AND DEVELOPMENT, 2020
WRF model have been tuned and tested over Georgia’s territory for years. First time in Georgia theprocess of data assimilation in Numerical weather prediction is developing. This work presents how forecasterror statistics appear in the data assimilation problem through the background error covariance matrix – B, wherethe variances and correlations ...

Robotic Arm‐Assisted Conformal 3D Printing of Displays for Structural Electronics

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents a robotics‐enabled platform combining 3D scanning and a 6‐DOF robotic arm for conformal printing on complex non‐planar structures. By maintaining nozzle perpendicularity, the system enables high‐fidelity direct ink writing on steep sidewalls, spherical surfaces, successfully demonstrating a fully printed 7‐segment dynamic display ...

Evaluation of the Effect of Regional Pollutants and Residual Ozone on Ozone Concentrations in the Morning in the Inland of the Kanto Region

open access: yesAsian Journal of Atmospheric Environment, 2015
Increasing ozone concentrations are observed over Japan from year to year. One cause of high ozone concentration in the Kanto region, which includes areas inland from large coastal cities such as metropolitan Tokyo, is the transportation of precursors by

Detection of Methane Emission from a Local Source Using GOSAT Target Observations

open access: yesRemote Sensing, 2020
Emissions of atmospheric methane (CH4), which greatly contributes to radiative forcing, have larger uncertainties than those for carbon dioxide (CO2). The Thermal And Near-infrared Sensor for carbon Observation Fourier-Transform Spectrometer (TANSO-FTS ...

eGFR slope as predictor of mortality in heart failure patients

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1217-1226, April 2025.
Abstract Aims Heart failure (HF) leads to an imbalance between heart and kidney function, resulting in poor outcomes. However, the prognostic significance of the estimated glomerular filtration rate (eGFR) trajectory in HF patients remains unclear. We analysed electronic health records (EHRs) of real‐world HF patients, assessing eGFR trajectories and ...

Using the Regional Ocean Modelling System (ROMS) to improve the sea surface temperature predictions of the MERCATOR Ocean System

open access: yesScientia Marina, 2012
Global models are generally capable of reproducing the observed trends in the globally averaged sea surface temperature (SST). However, the global models do not perform as well on regional scales.
