Natural convection in a circular enclosure with an internal cylinder of regular polygon geometry

open access: yesAIP Advances, 2019
This work presents a numerical investigation on the natural convection heat transfer in a circular enclosure with an internal cylinder at Ra=103-106 in both conduction and convection dominant regimes.

Morphological and Hyperphosphorylation Transitions of Nanoscale Tau Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Super‐resolution microscopy identifies nano‐sized tau aggregates (nano‐aggregates) and reveals distinct transitions in their morphology and phosphorylation profiles across control, Primary Age‐Related Tauopathy, and Alzheimer's disease brains. Morphology and hyperphosphorylation signatures distinguish physiological from pathological forms, with nano ...

Geometric Singularities of the Stokes Problem

open access: yesAbstract and Applied Analysis, 2014
When the domain is a polygon of ℝ2, the solution of a partial differential equation is written as a sum of a regular part and a linear combination of singular functions.

A NEW, EFFECTIVE METHOD FOR COMPUTING THE INTERACTION POTENTIAL OF HARD CYCLIC MULTIMER SYSTEMS

open access: yesTASK Quarterly, 2015
Studies of efficiency of several methods for calculating the interaction potential of a pair of two-dimensional hard cyclic multimers – molecules formed by hard disks (atoms) placed at the vertices of a regular polygon – are reported in this work.

REEP1 Accumulation Disrupts ER Integrity and Drives Spinal Motoneuron Degeneration in Distal Hereditary Motor Neuropathy

open access: yesAdvanced Science, EarlyView.
REEP1 contributes to endoplasmic reticulum (ER) shaping. Variants either cause cortical motoneuron degeneration and hereditary spastic paraplegia (HSP) or spinal motoneuron degeneration and distal hereditary motor neuropathy (dHMN). Knockout causes less complex ER structures and cortical motoneuron loss.

Quasi-Exact Coulomb Dynamics of n Charges n-1 of Which Are Equal

open access: yesAdvances in Mathematical Physics, 2017
For n≥3 point charges n-1 of which are negative and equal quasi-exact periodic solutions of their Coulomb equation of motion are found. These solutions describe a motion of the negative charges around a coordinate axis in such a way that their ...

Disordered Glass Nanowire Substrates Produce in Vivo‐Like Astrocyte Morphology Revealed by Low‐Coherence Holotomography

open access: yesAdvanced Science, EarlyView.
Low‐coherence holotomography reveals that disordered nanowire substrates guide astrocyte morphology toward branched, in vivo–like star‐shaped morphology, emphasizing the role of biophysical cues in shaping neural cell behavior. The developed nanostructured platform offers a new route to study astrocytes for neurobiology studies. Abstract Astrocytes are

Biomechanical Phenotyping Reveals Unique Mechanobiological Signatures of Early‐Onset Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies a unique physical signature of colorectal cancer in younger adults: their tissues are mechanically stiffer than those in older patients with the same cancer. Furthermore, stromal remodeling in early‐onset colorectal cancer promotes epithelial mechanotransduction and proliferation, showing how mechanical alterations in the tissue ...
