Fixed-Parameter Approximation Schemes for Weighted Flowtime [PDF]
, 2018 Given a set of n jobs with integral release dates, processing times and weights, it is a natural and important scheduling problem to compute a schedule that minimizes the sum of the weighted flow times of the jobs.

Using fluorescence fluctuation spectroscopy to quantify molecular dynamics within cells
FEBS Open Bio, EarlyView.Microscopy techniques like fluorescence correlation spectroscopy (FCS) and number and brightness analysis (N&B) allow to quantify concentrations, diffusion rates, and oligomerization of fluorescently labeled molecules in the living cell. In this protocol the principles of how to set up these types of experiments are described including calibration ...

An upper bound on the inhomogeneous approximation constants
For an irrational real $α$ and $γ\not \in \mathbb Z + \mathbb Zα$ it is well known that $$ \liminf_{|n|\rightarrow \infty} |n| ||nα-γ|| \leq \frac{1}{4}. $$ If the partial quotients, $a_i,$ in the negative `round-up' continued fraction expansion of $α$ have $R:=\liminf_{i\rightarrow \infty}a_i$ odd, then the 1/4 can be replaced by $$ \frac{1}{4}\left(1-

Upper and lower bounds on approximating weighted mixed domination [PDF]
Theoretical Computer Science, 2019 A mixed dominating set of a graph $G = (V, E)$ is a mixed set $D$ of vertices and edges, such that for every edge or vertex, if it is not in $D$, then it is adjacent or incident to at least one vertex or edge in $D$. The mixed domination problem is to find a mixed dominating set with a minimum cardinality. It has applications in system control and some

In vitro generation of regulatory T cells: A challenging tool for studying immune aging in humans
FEBS Open Bio, EarlyView.In vitro induction of human regulatory T cells using standard protocols generates suppressive, Foxp3‐expressing CD4+ T cells independently of TGF‐β supplementation and donor age. Regulatory T (Treg) cells play a key role in immune tolerance and homeostasis.

Three-Way Approximations with Covering-Based Rough Set
AxiomsIn order to approximate an undefinable set of objects by using the extensions in OE-concept lattices, this study combines three-way concept analysis with covering-based rough set and introduces an innovative approach for managing uncertain information ...

Upper semicontinuous functions and the stone approximation theorem
Journal of Approximation Theory, 1982 In convex function theory it has long been recognized as useful to identify a convex function with its epigraph, the convex set of points on or above its graph. Similarly, a concave function is identified with its hypograph, the convex set of points on or below its graph. Analysis is then performed in the product space. We present two standard examples.

Approximation of Mappings with Values Which Are Upper Semicontinuous Functions
Journal of Approximation Theory, 2001 Denote by \(\mathcal F ( \mathbb{R}^{p}) \) the class of functions \(V:\mathbb{R}^{p}\to[ 0,1] \) which are upper semicontinuous and have compact support supp\( V\). For \(V\in\mathcal F ( \mathbb{R}^{p}) \) let \(V_{\alpha}=\{ x\in\mathbb{R} ^{p}:V( x) \geq\alpha\} ,\alpha>0\), and \(V_{0}=\) supp\( V\).

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora
FEBS Open Bio, EarlyView.This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.
