Battle Between HF and UHF RFID

, 2008
Recently, much of the focus has been on UHF passive tags compared to the more established HF (13.56 MHz) and LF (125 to 134.2 kHz) technologies. The 860 to 956 MHz range of UHF has attracted most of the R&D investments.

Evaluation of Anticipated Performance Index of Plant Species for Green Belt Development to Mitigate Air Pollution

International Journal of Bio-Resource and Stress Management, 2020
Anticipated Performance Index (API) is an innovative ecological approach in selecting plant species for reducing air pollution, using Air Pollution Tolerance Index (APTI) and socio-economic parameters. The present study evaluated API of 11 plant species

Fat/Water Separation at 7 T Using a 3D Radial Sequence With Quasi‐Continuous Echo Times

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 96-108, July 2026.
ABSTRACT Purpose To achieve a reliable fat/water separation (FWS) at 7 T using a new 3D radial sequence and reconstruction workflow with quasi‐continuous TE sampling. Methods A 3D radial density‐adapted sequence with quasi‐continuous TE sampling was developed for a 7 T whole‐body MRI system.

A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 469-484, July 2026.
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

MRI Goes Mobile: Assessing the Reliability and Repeatability of a Mobile vs. Stationary 1.5 T MRI for Functional Neuroscience Studies

NMR in Biomedicine, Volume 39, Issue 7, July 2026.
We present a technical feasibility study validating two mobile 1.5 T MRI scanners against a stationary system using a five‐subject test‐retest protocol (N = 50 datasets). Following relocation, hardware performance remained stable, with no systematic bias in B0 homogeneity or B1+ maps.

Acute toxicity patterns and their management after moderate and ultra- hypofractionated radiotherapy for prostate cancer: A prospective cohort study

Clinical and Translational Radiation Oncology
Objective: Hypofractionation has become the new clinical standard for prostate cancer. We investigated the management of acute toxicity in patients treated with moderate hypofractionation (MHF) or Ultrahypofractionation (UHF).

A Hydrogen‐Bonded Organic Biradical in the Gas Phase

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
Hydrogen‐bonded dimers of the TEMPOL radical are investigated by vibrational spectroscopy in the gas phase and shown to occur in at least two conformations, a stretched one with a strong hydrogen bond to the radical centre and a bent one with more pronounced London dispersion interactions. ABSTRACT Persistent organic radicals from the TEMPO family such
