2. Analysis of fluid velocity vector field divergence $\nabla\cdot\vec{u}$ in function of variable fluid density $\rho(\vec{x},t)\neq const$ and conditions for vanishing viscosity of compressible Navier-Stokes equations

Abstract

In this paper, we perform analysis of the fluid velocity vector field divergence $\nabla \cdot \vec{u}$ derived from the continuity equation, and we explore its application in the Navier-Stokes equations for compressible fluids $\rho (\vec{x},t)\ne const$, occupying all of $\vec{x}\in R^{3} $ space at any $t\geq 0$. The resulting velocity vector field divergence $\nabla \cdot \vec{u}=-\frac{1}{\rho } (\frac{\partial \rho }{\partial t} +\vec{u}\cdot \nabla \rho )$ is a direct consequence of the fluid density rate of change over time $\frac{\partial \rho }{\partial t}$ and over space $\nabla \rho $, in addition to the fluid velocity vector field $\vec{u}(\vec{x},t)$ and the fluid density $\rho (\vec{x},t)$ itself. We derive the conditions for the divergence-free fluid velocity vector field $\nabla \cdot \vec{u}=0$ in scenarios when the fluid density is not constant $\rho(\vec{x},t)\neq const$ over space nor time, and we analyze scenarios of the non-zero divergence $\nabla \cdot \vec{u}\ne 0$. We apply the statement for divergence in the Navier-Stokes equation for compressible fluids, and we deduct the condition for vanishing (zero) viscosity term of the compressible Navier-Stokes equation: $\nabla (\frac{1}{\rho } (\frac{\partial \rho }{\partial t} +\vec{u}\cdot \nabla \rho ))=-3\Delta \vec{u}$. In addition to that, we derive even more elementary condition for vanishing viscosity, stating that vanishing viscosity is triggered once scalar function $d(\vec{x},t)=-\frac{1}{\rho } (\frac{\partial \rho }{\partial t} +\vec{u}\cdot \nabla \rho )$ is harmonic function. Once that condition is satisfied, the viscosity related term of the Navier-Stokes equations for compressible fluids equals to zero, which is known as related to turbulent fluid flows., Comment: 13 pages

3. Incompressible Navier-Stokes Equations: Example of no solution at $R^3$ and $t=0$

Physics - Fluid Dynamics, 76D05
Abstract

We provide an example of a smooth, divergence-free $\nabla \cdot \vec{u}(\vec{x})=0$ velocity vector field $\vec{u}(\vec{x})$ for incompressible fluid occupying all of $R^{3}$ space, and smooth vector field $\vec{f}(\vec{x}, t)$ for which the Navier-Stokes equation for incompressible fluid does not have a solution for any position in space $\vec{x}\in R^{3} $ at $t=0$. The velocity vector field $u_{i} (\vec{x})=2\frac{x_{h(i-1)} -x_{h(i+1)} }{\left(1+\sum _{j=1}^{3}x_{j}^{2} \right)^{2} }$ ; $i=\{ 1,2,3\} $ where $h(l)=\left\{\begin{array}{ccc} {l} & {;1\le l\le 3} & {} \\ {1} & {;l=4} & {} \\ {3} & {;l=0} & {} \end{array}\right.$ is smooth, divergence-free, continuously differentiable $u(\vec{x})\in C^{\infty }$, has bounded energy $\int _{R^{3} }\left|\vec{u}\right|^{2} dx=\pi ^{2}$, zero velocity at coordinate origin, and velocity converges to zero for $\left|\vec{x}\right|\to \infty$. The vector field $\vec{f}(\vec{x},t)=(0,0,\frac{1}{1+t^{2} (\sum _{j=1}^{3}x_{j} )^{2} )} $ is smooth, continuously differentiable $f(\vec{x},t)\in C^{\infty }$, converging to zero for $\left|\vec{x}\right|\to \infty$. Applying $\vec{u}(\vec{x})$ and $\vec{f}(\vec{x}, t)$ in the Navier-Stokes equation for incompressible fluid results with three mutually different solutions for pressure $p(\vec{x}, t)$, one of which includes zero division with zero $\frac{0}{0}$ term at $t=0$, which is indeterminate for all positions $\vec{x} \in R^{3}$.

Abstract

Upon stimulation of membrane receptors, nicotinic acid adenine dinucleotide phosphate (NAADP) is formed as second messenger within seconds and evokes Ca2+ signaling in many different cell types. Here, to directly stimulate NAADP signaling, MASTER-NAADP, a Membrane permeAble, STabilized, bio-rEversibly pRotected precursor of NAADP is synthesized and release of its active NAADP mimetic, benzoic acid C-nucleoside, 2'-phospho-3'F-adenosine-diphosphate, by esterase digestion is confirmed. In the presence of NAADP receptor HN1L/JPT2 (hematological and neurological expressed 1-like protein, HN1L, also known as Jupiter microtubule-associated homolog 2, JPT2), this active NAADP mimetic releases Ca2+ and increases the open probability of type 1 ryanodine receptor. When added to intact cells, MASTER-NAADP initially evokes single local Ca2+ signals of low amplitude. Subsequently, also global Ca2+ signaling is observed in T cells, natural killer cells, and Neuro2A cells. In contrast, control compound MASTER-NADP does not stimulate Ca2+ signaling. Likewise, in cells devoid of HN1L/JPT2, MASTER-NAADP does not affect Ca2+ signaling, confirming that the product released from MASTER-NAADP is a bona fide NAADP mimetic. Upon stimulation of receptors, NAADP is formed as calcium-mobilizing second messenger in many cells. Here, the authors develop MASTER-NAADP, a membrane-permeant precursor of NAADP, and characterize its biological activity. [ABSTRACT FROM AUTHOR]

5. DARTS: an open-source Python pipeline for Ca2+ microdomain analysis in live cell imaging data.

Abstract

Ca2+ microdomains play a key role in intracellular signaling processes. For instance, they mediate the activation of T cells and, thus, the initial adaptive immune system. They are, however, also of utmost importance for activation of other cells, and a detailed understanding of the dynamics of these spatially localized Ca2+ signals is crucial for a better understanding of the underlying signaling processes. A typical approach to analyze Ca2+ microdomain dynamics is live cell fluorescence microscopy imaging. Experiments usually involve imaging a larger number of cells of different groups (for instance, wild type and knockout cells), followed by a time consuming image and data analysis. With DARTS, we present a modular Python pipeline for efficient Ca2+ microdomain analysis in live cell imaging data. DARTS (Deconvolution, Analysis, Registration, Tracking, and Shape normalization) provides state-of-the-art image postprocessing options like deep learning-based cell detection and tracking, spatio-temporal image deconvolution, and bleaching correction. An integrated automated Ca2+ microdomain detection offers direct access to global statistics like the number of microdomains for cell groups, corresponding signal intensity levels, and the temporal evolution of the measures. With a focus on bead stimulation experiments, DARTS provides a so-called dartboard projection analysis and visualization approach. A dartboard projection covers spatiotemporal normalization of the bead contact areas and cell shape normalization onto a circular template that enables aggregation of the spatiotemporal information of the microdomain detection results for the individual cells of the cell groups of interest. The dartboard visualization allows intuitive interpretation of the spatio-temporal microdomain dynamics at the group level. The application of DARTS is illustrated by three use cases in the context of the formation of initial Ca2+ microdomains after cell stimulation. DARTS is provided as an open-source solution and will be continuously extended upon the feedback of the community. [ABSTRACT FROM AUTHOR]

9. Empirical evidence for the bank lending channel in Bosnia and Herzegovina: Does lending differ between large and small banks?

Abstract

The paper investigates transmission of different foreign and domestic shocks to bank lending activity in Bosnia and Herzegovina through the bank lending channel. The bank lending channel is analyzed in a time series cross sectional data framework for the period 2006q1-2014q1, investigating reactions of small vs. large banks to those shocks. First, the evidence has been found that both groups of banks decreased their lending activity in the aftermath of the crisis. There is some evidence that liquidity shock after the onset of the crisis is mainly transmitted through large banks that are affiliates of the large Western European banking groups. Second, strong evidence is found that loosening of domestic monetary conditions through required reserves rate change had a positive effect on lending supply, especially for small banks operating in the country.
