The Simulation of the Inelastic Impact

open access: yes, 2003
The coefficient of normal restitution (COR) in an oblique impact is theoretically studied. Using a two-dimensional lattice models for an elastic disk and an elastic wall, we investigate the dependency of COR on an incident angle and demonstrate that COR ...

Age-dependent sensitization to the 7S-vicilin-like protein Cor a 11 from hazelnut (Corylus avellana) in a birch-endemic region [PDF]

open access: yes, 2012
Background: Hazelnut (Corylus avellana) allergy exhibits age and geographically distinct sensitization patterns that have not yet been fully resolved. Objective: To study sensitization to Cor a 11 in different age groups of hazelnut-allergic patients and

An algebra of deformation quantization for star-exponentials on complex symplectic manifolds [PDF]

open access: yes, 2006
The cotangent bundle $T^*X$ to a complex manifold $X$ is classically endowed with the sheaf of $\cor$-algebras $\W[T^*X]$ of deformation quantization, where $\cor\eqdot \W[\rmptt]$ is a subfield of $\C[[\hbar,\opb{\hbar}]$. Here, we construct a new sheaf

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Loculated empyema in a neonate successfully treated with chest tube thoracostomy and antibiotics

open access: yesRespiratory Medicine Case Reports, 2020
Empyema thoracis, defined as the accumulation of pus in the pleural space, is a rare entity in the neonatal period. There are very few cases described in the medical literature and there are still no treatment protocols in the management of empyema in ...

Cor triatriatum sinister with situs inversus totalis in an infant. [PDF]

open access: yes, 2012
Cor triatriatum sinister is a rare congenital cardiac malformation characterized by a membrane in the left atrium which separates the left atrium into the proximal and distal chambers.Association of cor triatriatum is extremely rare with situs inversus

Collision of One-Dimensional Nonlinear Chains

open access: yes, 2002
We investigate one-dimensional collisions of unharmonic chains and a rigid wall. We find that the coefficient of restitution (COR) is strongly dependent on the velocity of colliding chains and has a minimum value at a certain velocity.

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

open access: yesMolecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

Differential misestimation of maximum fluorescence yields can confound efforts to optimize photosynthesis

open access: yesScientific Reports
Efforts to optimize photosynthesis can be informed by measurement of it’s underlying and coordinated sub-processes. For decades, non-invasive techniques have been integrated to enable assessment of the coordination that exists within and between the ...
