Time-dependent quasi-spherical accretion [PDF]
Differentially rotating, "advection-dominated" accretion flows are considered in which the heat generated by viscous dissipation is retained in the fluid. The equations of time-dependent quasi-spherical accretion are solved in a simplified one-dimensional model that neglects the latitudinal dependence of the flow.

Time-Dependent of Accretion Flow with Toroidal Magnetic Field [PDF]
In the present study time evolution of quasi-spherical polytropic accretion flow with toroidal magnetic field is investigated. The study especially focused the astrophysically important case in which the adiabatic exponent $\gamma=5/3$. In this scenario, it was assumed that the angular momentum transport is due to viscous turbulence and used $\alpha ...

Flow‐Induced Vascular Remodeling on‐Chip: Implications for Anti‐VEGF Therapy
Flow‐induced vascular remodeling plays a critical role in network stabilization and function. Using a vasculature‐on‐chip system, this study reveals how physiological VEGF levels and flow affect vascular remodeling and provides insights into tumor vessel normalization.

The molecular genetics of RASopathies: An update on novel disease genes and new disorders
Abstract Enhanced signaling through RAS and the mitogen‐associated protein kinase (MAPK) cascade underlies the RASopathies, a family of clinically related disorders affecting development and growth. In RASopathies, increased RAS‐MAPK signaling can result from the upregulated activity of various RAS GTPases, enhanced function of proteins positively ...

Formation of Pancreatoduodenal Fistula in Intraductal Papillary Mucinous Neoplasm of the Pancreas Decreased the Frequency of Recurrent Pancreatitis [PDF]
Intraductal papillary mucinous neoplasms (IPMN) of the pancreas are characterized by proliferation of mucin-secreting cells in the main pancreatic duct (PD) or its branches. The secreted thick mucin usually leads to PD obstruction and dilation.

Clinical overview on RASopathies
Abstract RASopathies comprise a group of clinically overlapping developmental disorders caused by genetic variations affecting components or modulators of the RAS‐MAPK signaling cascade, which lead to dysregulation of signal flow through this pathway.

Heavy Exotic Molecules with Charm and Bottom [PDF]
We revisit the formation of pion-mediated heavy-light exotic molecules with both charm and bottom and their chiral partners under the general strictures of both heavy-quark and chiral symmetry. The chiral exotic partners with good parity formed using the $(0^+, 1^+)$ multiplet are about twice more bound than their primary exotic partners formed using ...
