Research of spatial distribution of electromagnetic fields of industrial frequency in the central part of the city of Saratov [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Науки о Земле
The cartographic research of electric and magnetic fields of industrial frequency in the central part of Saratov was performed. Measurements by means of the Gigahertz Solutions ME 3830 B M/E Analyser were executed in the 177 points within the built-up ...

Second-order phase transition of silicon from a band insulator to metal induced by strong magnetic fields [PDF]

open access: yesarXiv, 2022
We present the second-order phase transition from a band insulator to metal that is induced by a strong magnetic field. The magnetic-field dependences of the magnetization and energy band gap of a crystalline silicon immersed in a magnetic field are investigated by means of the nonperturbative magnetic-field-containing relativistic tight-binding ...

A Concept for 6D Motion Sensing with Magnetoelectric Sensors

open access: yesCurrent Directions in Biomedical Engineering, 2022
Active magnetic motion sensing relies on a combination of magnetic sensors and actuators to indirectly sense a time-varying change in position and orientation.

Magnetic fluctuations and formation of large-scale inhomogeneous magnetic structures in a turbulent convection [PDF]

open access: yesPhys.Rev.E76:056307,2007, 2007
Magnetic fluctuations generated by a tangling of the mean magnetic field by velocity fluctuations are studied in a developed turbulent convection with large magnetic Reynolds numbers. We show that the energy of magnetic fluctuations depends on magnetic Reynolds number only when the mean magnetic field is smaller than $B_{eq} / 4 Rm^{1/4}$, where $B_{eq}

MAGNETIC FIELDS IN HIGH-MASS INFRARED DARK CLOUDS [PDF]

open access: yes, 2014
High-mass stars are cosmic engines known to dominate the energetics in the Milky Way and other galaxies. However, their formation is still not well understood.

How to use magnetic field information for coronal loop identification? [PDF]

open access: yesSolar Phys.228:67,2005, 2008
The structure of the solar corona is dominated by the magnetic field because the magnetic pressure is about four orders of magnitude higher than the plasma pressure. Due to the high conductivity the emitting coronal plasma (visible e.g. in SOHO/EIT) outlines the magnetic field lines. The gradient of the emitting plasma structures is significantly lower

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

open access: yesFEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Transforming magnets [PDF]

open access: yes, 2014
Based on the form-invariant of Maxwell's equations under coordinate transformations, we extend the theory of transformation optics to transformation magneto-statics, which can design magnets through coordinate transformations. Some novel DC magnetic field illusions created by magnets (e.g.

Potential analysis of holographic Schwinger effect in the magnetized background [PDF]

open access: yesEur. Phys. J. C (2020) 80:550, 2019
We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $B\ll T^2$ and $B\gg T^2$ solutions respectively. Firstly, we calculate separating length of the particle pairs at finite magnetic field.

Unlocking the potential of tumor‐derived DNA in urine for cancer detection: methodological challenges and opportunities

open access: yesMolecular Oncology, EarlyView.
Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...
