A ring-shaped conductor with radius a carries a total charge Q uniformly distributed around it. Find the electric field at a point P that lies on the axis of the ring at a distance x from its Center. Let me point out that "the axis of the ring" is perpendicular to the plane of ...
(~400 ms), the mobility of Pal-PAmCherry in both dividing and non-dividing cells is slow and highly restricted (median apparent diffusion coefficient, ~0.004 µm2 s−1; median confinement radius, ~83 nm; median trajectory localisation uncertainty, 19.3 nm). Slow Pal ...
Nuclear Pore Complexes (NPCs) regulate bidirectional transport between the nucleus and the cytoplasm. Intrinsically disordered FG-Nups line the NPC lumen and form a selective barrier, where transport of most proteins is inhibited whereas specific transpo
A meaningful consequence of the above relations is that, in correspondence of the value 𝑟0=𝛿𝑘/𝜔r0=δk/ω, the magnetic field is zero and the electric field is tangential to the cylinder of radius 𝑟0r0 (see (7)). According to (11), the variation in time of 𝐁B is ...

Electrical double layer (EDL) is a basic concept in electrochemistry. When the electrode is charged and put into a solution with ions, the interface of the charged electrode and ions rich solution will be occupied with counter ions as a result of the Coulomb force, forming EDL. Diminishing th...
Transient oligomeric species formed during the aggregation process of the 42-residue form of the amyloid-β peptide (Aβ42) are key pathogenic agents in Alzheimer’s disease (AD). To investigate the relationship between Aβ42 aggregation and its cytotoxi
