This laboratory study examined how temperature and prior electric-field exposure affect low-field conductivity in the charge density wave material o-TaS3. Conductivity differed between cooling and heating below the CDW transition, and applying increasing electric fields drove the system toward a stable,…

This in vitro study tested electromagnetic compatibility between passive RFID readers and 15 pacemakers plus 15 ICDs across 134 kHz, 13.56 MHz, and 915 MHz bands. EMI reactions were common with low-frequency RFID and rare with high-frequency RFID, while no reactions were observed with ultra-high-frequency or…

This SCENIHR Opinion updates earlier 2009 SCENIHR documents on EMF health effects and research needs, focusing on new information and remaining knowledge gaps. The abstract primarily characterizes sources and patterns of exposure across static, ELF, IF, and RF fields in both public and occupational settings. It notes…

This monocentric study evaluated outpatient feasibility and outcomes of radiofrequency transurethral needle ablation (TUNA) for benign prostatic hyperplasia in patients who did not respond to medical therapy. In the outpatient subgroup, urinary symptom scores, quality of life, flow measures, and residual urine…

This in vitro study analyzed where magnetic stimulation activates pig phrenic nerves when induced electric fields are oriented longitudinally versus transversely to the nerve trunk. Longitudinal-field stimulation localized activation near the negative peak of the spatial derivative of the longitudinal electric field,…

This paper reports on pulsed radiofrequency treatment as an interventional approach for pain due to chronic benign pancreatitis. The authors describe their experience in two patients and characterize the technique as minimally neurodestructive and potentially able to reduce pain perception by altering nerve…

This paper describes a procedural technique for transseptal puncture that uses brief pulses of radiofrequency energy delivered from a standard electrosurgical cautery generator through the needle tip. The approach is presented as a way to facilitate septal traversal when tissue is elastic, aneurysmal, or thickened,…

This paper reports four experiments examining how a ringing cell phone affects cognitive performance in laboratory tasks and a college classroom lecture. In the lab, auditory conditions (including a standard cell phone ring) produced slower responses than silence, with slower recovery in the ring and song conditions.…

This engineering study measures and simulates screening current induced magnetic fields (SCF) in a Bi2223-tape HTS insert used in an LTS/HTS NMR magnet at 77 K. SCF was induced by the insert self-field, an external 5-T background magnet, and their combination, and axial field distributions and temporal variations…

This paper reports electric-field control of magnetic anisotropy in a Permalloy layer exchange-coupled to a multiferroic BiFeO3 single crystal. The anisotropy is described as arising from magnetic coupling to canted spins in BiFeO3’s cycloidal antiferromagnetic structure. An electric field-induced polarization change…

This theoretical paper analyzes vortex solutions in two-component superconductors within a U(1) x U(1) Ginzburg-Landau framework. It reports that exponentially screened magnetic fields are only found in special cases, while most parameter choices yield delocalized magnetic fields with slowly decaying tails. It also…

This Physical Review Letters paper reports magnetotransport measurements on a gated LaAlO3/SrTiO3 interface to assess the main effect of an applied gate electric field. The authors find that mobility changes dominate over sheet carrier density changes (mobility variation reported as nearly fivefold larger). They also…

This engineering study describes a focused-ion-beam-assisted technique for fabricating reduced-size NdFeB nanomagnets and integrating them onto a thin-film bulk acoustic resonator (FBAR). After bonding the magnet, the FBAR showed a downshift in resonance frequency and a reduced quality factor. The magnetic behavior…

This engineering study examined how a DC bias electric field affects the resonance frequency shift of a PMN-PT/tin piezoelectric microcantilever sensor during humidity detection. The authors report that applying a bias field enhanced the relative resonance frequency shift, with a maximum enhancement of more than…

This study describes development and validation of a sham rTMS approach that combines a matched sham coil (for look/sound) with scalp electrical stimulation (for sensation). In back-to-back comparisons, TMS-naïve participants reportedly could not tell active from sham, whereas experienced participants could. The…

This cross-sectional web-based survey assessed parents' concerns about managing their children's diabetes and their attitudes toward a mobile-phone-integrated glucometer service that could transmit real-time glucose readings. Parents most commonly reported concerns about access to their child's health care provider,…

This randomized controlled trial evaluated low-power, low-frequency pulsed electromagnetic field (PEMF) therapy at 600 Hz and 800 Hz as an adjunct treatment for diabetic polyneuropathy. Thirty participants were randomized to 600 Hz PEMF, 800 Hz PEMF, or usual medical treatment for 12 days. The abstract reports…

This clinical report describes the use of radiofrequency (RF) technology in surgery of abdominal and thoracic parenchymatous organs in 17 patients. The authors report one complication (pleural effusion) and otherwise no additional organ complications in the abstract. They also describe a case of splenic preservation…

This engineering/materials study describes blending PLLA and PGA using microwave irradiation to produce PLGA-related blends with varying constituent concentrations. The authors report that FTIR, NMR, and DSC measurements indicate blending and cross-linking between the polymers. The abstract does not provide microwave…

This in vitro study reports that electric fields can control the velocity of microtubules gliding over a kinesin-coated surface. Assisting fields increased speed up to fivefold, while opposing fields slowed motion to zero, and sideways fields induced significant motion. The authors present a grab-and-release model to…

This prospective multicenter longitudinal trial evaluated arthroscopic thermal radiofrequency capsular shrinkage for chronic ankle instability in adults who failed conservative therapy. The study reports no clinically relevant improvement in mechanical stability, but substantial and statistically significant…
