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 cross-sectional questionnaire study of 196 parent–adolescent dyads examined how cell phone calling patterns relate to perceptions of truthfulness, parental knowledge, and family relationships. More frequent parental calling was associated with lower perceived truthfulness, and calls made when upset were linked…

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 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 engineering-focused study examines failure of needle-shaped specimens exposed to very high electric fields in field-ion microscopy. The authors report experiments indicating breakdown may be initiated by nanoparticles detached from a point anode. They propose a mechanism in which expanding cathode plasma…

This theoretical paper analyzes consequences of nonuniqueness of the external magnetic field B(r) in spin-polarized density functional theory. It reports that for ground states the energy functional is not differentiable with respect to spin density, but one-sided derivatives can exist. The work links these one-sided…

This study compared slow conventional air defrosting with fast radio frequency (RF) defrosting/tempering in lean beef (whole, minced, and comminuted) using drip loss, NMR relaxometry, and dielectric spectroscopy. RF thawing was associated with lower drip loss and lower micronutrient loss in drip than air thawing,…

This theoretical/engineering study models arrays of plasmonic core-shell nano-radiators positioned over layered substrates using a Green's function dipole approach. The model is validated with full-wave FDTD simulations. The authors report that nanoparticle arraying and multilayer substrate design can be used to…

This paper proposes metallic nanowires as complementary structures to metallic nanogaps for enhancing magnetic fields. It reports magnetic field enhancement up to a factor of 300 and presents a surface-impedance-based analytic theory that is numerically confirmed. The authors also report that, in the sub-skin-depth…

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 paper uses atomistic simulations to examine how a nonpolar nanoparticle suspended in water reorients under an applied electric field. The authors report that molecular-level effects increase the torque relative to continuum estimates and substantially speed up reorientation above a stated field threshold. The…

This theoretical/physics study investigates spectral properties of a spin-1/2 Heisenberg antiferromagnet on an anisotropic triangular lattice in a magnetic field. It reports that interchain interactions in a magnetic field generate dominant modes that behave as quasiparticles, featuring anomalous incommensurate…

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 paper presents a theoretical treatment of nanoparticle retention in quadrupole magnetic field-flow fractionation (QMgFFF) using a helical separation channel. It defines the retention ratio as the ratio of transit times for non-retained versus retained material. Equations are derived for angular and longitudinal…

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 cross-sectional survey assessed mobile phone ownership and use patterns among 309 medical science students in Yazd using a self-administered questionnaire. The abstract reports descriptive statistics on daily talking time, music listening, texting, and common locations of phone use. While the paper references…
