Functional parameters of spermatozoa obtained by a new selection device

open access: yesFEBS Open Bio, EarlyView.
This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.

Magnetized stars with differential rotation and a differential toroidal field

open access: yes, 2015
We have succeeded in obtaining magnetized equilibrium states with differential rotation and differential toroidal magnetic fields. If an internal toroidal field of a proto-neutron star is wound up from the initial poloidal magnetic field by differential ...

Investigation on the Parasitic Capacitance of High Frequency and High Voltage Transformers of Multi-Section Windings

open access: yesIEEE Access, 2020
Resonant converters are widely used in high voltage applications thanks to the soft switching technologies. The high frequency and high voltage (HFHV) transformer is the most complicated and important part to boost the voltage by tens or hundreds of ...

Microfluidic electro‐viscoelastic manipulation of extracellular vesicles

open access: yesFEBS Open Bio, EarlyView.
The electro‐viscoelastic manipulation as a potential method for separation of particles based on size. The particles introduced as a sheath flow migrate to the channel center under the influence of simultaneously applied electric field and pressure driven flow.

PB1F2 from Influenza A Virus Regulates the Interaction between Cytochrome C and Cardiolipin

open access: yesMembranes, 2022
PB1F2 is a membrane associated protein encoded by the influenza virus gene in the host. Similar to endogenous pro-apoptotic proteins, it acts on the mitochondria of the host immune cells, inducing apoptosis of the cells.

Spinal Cord Abnormalities in Early Pediatric Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Spinal cord lesions and atrophy in the cervical region are common in adult multiple sclerosis (MS) and correlate with disability. Whether similar abnormalities occur in pediatric MS patients is largely unknown. Clinical and MRI evaluations were performed in 38 pediatric MS patients and 13 healthy controls (HC).

How to use magnetic field information for coronal loop identification?

open access: yes, 2005
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.

Pulse Pressure, White Matter Hyperintensities, and Cognition: Mediating Effects Across the Adult Lifespan

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To investigate whether pulse pressure or mean arterial pressure mediates the relationship between age and white matter hyperintensity load and to examine the mediating effect of white matter hyperintensities on cognition. Methods Demographic information, blood pressure, current medication lists, and Montreal Cognitive Assessment ...

Spin Chain with Magnetic Field and Spinning String in Magnetic Field Background

open access: yes, 2006
We analyze the fast-moving string in the magnetic Melvin field background and find that the associated effective Lagrangian of string sigma model describes the spin chain model with external magnetic field.
