text: With this paper we contribute to the understanding of the success of 2-opt
based local search algorithms for solving the traveling salesman problem (TSP).
Although 2-opt is widely used in practice, it is hard to understand its success
from a theoretical perspective. We take a statistical approach and examine the
features of TSP instances that make the problem either hard or easy to solve.
As a measure of problem difficulty for 2-opt we use the approximation ratio that
it achieves on a given instance. Our investigations point out important features
that make TSP instances hard or easy to be approximated by 2-opt.

text: 'Purpose: The epithelial sodium channel (ENaC) is typically expressed in sodium-absorbing
epithelia. Several reports suggest that ENaC is also expressed in ocular tissues
and may play a role in aqueous humor secretion and glaucoma. However, the precise
localization of ENaC in the human eye is still unclear. Here, the authors studied
ENaC expression in 12 normal human donor eyes and in six eyes of patients with
glaucoma. Methods: Quantitative real-time PCR was used to investigate the expression
of $\alpha$-, $\beta$-, $\gamma$-, and $\delta$-ENaC transcripts in ocular tissues.
In addition, the authors performed immunohistochemical studies using recently
generated antibodies against human $\beta$- and $\gamma$-ENaC. Results: At the
mRNA level, all four ENaC subunits were found to be expressed in a wide range
of ocular tissues from normal and glaucomatous human eyes, with the cornea, ciliary
body, iris, and retina showing the highest expression levels. At the protein level,
$\beta$- and $\gamma$-ENaC subunits showed distinct distribution patterns and
could be immunolocalized primarily to the cell membranes of epithelial cells of
the cornea and to the conjunctiva, iris, ciliary body, lens, and retinal pigment
epithelium but also to vascular endothelial cells, smooth muscle cells, stromal
cells, and retinal neurons. The authors found no altered mRNA level of any subunit
in glaucomatous eyes. Conclusions: All four ENaC subunits ($\alpha$$\beta$$\gamma$$\delta$)
are expressed in the normal human eye, with distinct localization of subunits
possibly reflecting different functional states of the channel. The (patho-)physiological
roles of ENaC in the various localizations in the eye remain to be determined.'

text: 'Background: Increased expression of the pro-fibrotic protein connective tissue
growth factor (CTGF) has been detected in injured kidneys and elevated urinary
levels of CTGF are discussed as prognostic marker of chronic kidney disease. There
is evidence that epithelial cells lining the renal tubular system contribute to
uptake and secretion of CTGF. However, the role of different types of tubular
epithelial cells in these processes so far has not been addressed in primary cultures
of human cells. Results: Tubular epithelial cells of proximal and distal origin
were isolated from human kidneys and cultured as polarized cells in insert wells.
The pro-fibrotic stimuli lysophosphatidic acid (LPA) and transforming growth factor
$\beta$ (TGF-$\beta$) were used to induce CTGF secretion.LPA activated CTGF secretion
in proximal tubular cells when applied from either the apical or the basolateral
side as shown by immunocytochemistry. CTGF was secreted exclusively to the apical
side. Signaling pathways activated by LPA included MAP kinase and Rho kinase signaling.
TGF-$\beta$ applied from either side also stimulated CTGF secretion primarily
to the apical side with little basolateral release.Interestingly, TGF-$\beta$
activation induced different signaling pathways depending on the side of TGF-$\beta$
application. Smad signaling was almost exclusively activated from the basolateral
side most prominently in cells of distal origin. Only part of these cells also
synthesized CTGF indicating that Smad activation alone was not sufficient for
CTGF induction. MAP kinases were involved in apical TGF-$\beta$-mediated activation
of CTGF synthesis in proximal cells and a subset of epithelial cells of distal
origin. This subpopulation of distal tubular cells was also able to internalize
recombinant apical CTGF, in addition to proximal cells which were the main cells
to take up exogenous CTGF. Conclusions: Analysis of polarized human primary renal
epithelial cells in a transwell system shows that vectorial secretion of the pro-fibrotic
protein CTGF depends on the cell type, the stimulus and the signaling pathway
activated. In all conditions, CTGF was secreted mainly to the apical side upon
TGF-$\beta$ and LPA treatment and therefore, likely contributes to increased urinary
CTGF levels in vivo. Moreover, CTGF secreted basolaterally may be active as paracrine
pro-fibrotic mediator.'

text: Aldosterone is thought to be the main hormone to stimulate the epithelial
sodium channel (ENaC) in the aldosterone-sensitive distal nephron (ASDN) comprising
the late distal convoluted tubule (DCT2), the connecting tubule (CNT) and the
entire collecting duct (CD). There is immunohistochemical evidence for an axial
gradient of ENaC expression along the ASDN with highest expression in the DCT2
and CNT. However, most of our knowledge about renal ENaC function stems from studies
in the cortical collecting duct (CCD). Here we investigated ENaC function in the
transition zone of DCT2/CNT or CNT/CCD microdissected from mice maintained on
different sodium diets to vary plasma aldosterone levels. Single-channel recordings
demonstrated amiloride-sensitive Na(+) channels in DCT2/CNT with biophysical properties
typical for ENaC previously described in CNT/CCD. In animals maintained on a standard
salt diet, the average ENaC-mediated whole cell current ($\Delta$I(ami)) was higher
in DCT2/CNT than in CNT/CCD. A low salt diet increased $\Delta$I(ami) in CNT/CCD
but had little effect on $\Delta$I(ami) in DCT2/CNT. To investigate whether aldosterone
is necessary for ENaC activity in the DCT2/CNT, we used aldosterone synthase knockout
(AS(-/-)) mice that lack aldosterone. In CNT/CCD of AS(-/-) mice, $\Delta$I(ami)
was lower than that in wild-type (WT) animals and was not stimulated by a low
salt diet. In contrast, in DCT2/CNT of AS(-/-) mice, $\Delta$I(ami) was similar
to that in DCT2/CNT of WT animals both on a standard and on a low salt diet. We
conclude that ENaC function in the DCT2/CNT is largely independent of aldosterone
which is in contrast to its known aldosterone sensitivity in CNT/CCD.

text: 'Background: Renal tubular epithelial cells of proximal and distal origin
differ markedly in their physiological functions. Therefore, we hypothesized that
they also differ in their capacity to undergo epithelial to mesenchymal alterations.
Results: We used cultures of freshly isolated primary human tubular cells. To
distinguish cells of different tubular origin we took advantage of the fact that
human proximal epithelial cells uniquely express N-cadherin instead of E-cadherin
as major cell-cell adhesion molecule. To provoke mesenchymal alteration we treated
these cocultures with TGF-$\beta$ for up to 6 days. Within this time period, the
morphology of distal tubular cells was barely altered. In contrast to tubular
cell lines, E-cadherin was not down-regulated by TGF-$\beta$, even though TGF-$\beta$
signal transduction was initiated as demonstrated by nuclear localization of Smad2/3.
Analysis of transcription factors and miRNAs possibly involved in E-cadherin regulation
revealed high levels of miRNAs of the miR200-family, which may contribute to the
stability of E-cadherin expression in human distal tubular epithelial cells. By
contrast, proximal tubular epithelial cells altered their phenotype when treated
with TGF-$\beta$. They became elongated and formed three-dimensional structures.
Rho-kinases were identified as modulators of TGF-$\beta$-induced morphological
alterations. Non-specific inhibition of Rho-kinases resulted in stabilization
of the epithelial phenotype, while partial effects were observed upon downregulation
of Rho-kinase isoforms ROCK1 and ROCK2. The distinct reactivity of proximal and
distal cells was retained when the cells were cultured as polarized cells. Conclusions:
Interference with Rho-kinase signaling provides a target to counteract TGF-$\beta$-mediated
mesenchymal alterations of epithelial cells, particularly in proximal tubular
epithelial cells. Furthermore, primary distal tubular cells differed from cell
lines by their high phenotypic stability which included constant expression of
E-cadherin. Our cell culture system of primary epithelial cells is thus suitable
to understand and modulate cellular remodeling processes of distinct tubular cells
relevant for human renal disease.'

text: An alternating optimization algorithm was recently proposed for the K-user
multiple-input multiple-output (MIMO) interference channel. For flat-fading channels
and feasible problems, this algorithm successfully aligns the interfering signals
exploiting the spatial dimensions. In this paper, we consider the case in which
all pairwise MIMO channels are frequency-selective (convolutive), and the users
transmit broadband signals using a single-carrier scheme. Unlike the flat-fading
case, for frequency-selective channels it is necessary to add a spectral mask
in the frequency response of the precoders and decoders to avoid trivial solutions.
We show in the paper that each step of the alternating minimization algorithm
can be reformulated as a convex optimization problem in which the autocorrelation
function of the precoders or decoders is obtained. Upon convergence, a final spectral
factorization stage must be applied to obtain the precoders and decoders from
their autocorrelation functions. Simulation results are provided to illustrate
the performance of the proposed algorithm.

text: This paper considers large multiple-input multiple-output (MIMO) communication
systems with linear precoding and linear minimum mean-squared error (LMMSE) equalization
based on the iterative conjugate gradient (CG) algorithm. Convergence of the CG
algorithm is fast when the eigenvalues of the received signal’s covariance matrix
are clustered, suggesting that mean-squared error and receiver complexity can
be managed with judicious precoder design. In order to accelerate convergence
of an iterative CG receiver, we incorporate constraints on two measures of eigenvalue
clustering into the precoder design. Closed-form solutions to the optimal precoders
are derived using majorization theory and convex optimization techniques. We show
that if there are constraints on receiver complexity, the proposed precoders can
improve performance for large MIMO systems operating over slowly time-varying
fading channels.

text: "Paper Abstract\r\nHigh harmonic generation is investigated for a two-band
model of a semiconductor nanostructure. Similar to an atomic two-level system,
the semiconductor emits high harmonic radiation. We show how one can specifically
enhance the emission for a given frequency by applying a non-trivially shaped
laser pulse. Therefore, the semiconductor Bloch equations including the interband
and additionally the intraband dynamics are solved numerically and the spectral
shape of the input pulse is computed via an optimization algorithm. It is demonstrated
that desired emission frequencies can be favored even though the overall input
power is kept constant. We also suggest special metallic nano geometries to achieve
enhanced localized optical fields. They are found by geometric optimization."

text: The generation of specific high harmonics for an optical two-level system
is elucidated. The desired emitted radiation can be induced by a carefully designed
excitation pulse, which is found by a multiparameter optimization procedure. The
presented mechanism can also be applied to semiconductor structures for which
the calculations result in much higher emission frequencies. The optimization
procedure is either performed using a genetic algorithm or a rigorous mathematical
optimization technique.

text: Digital 3D models are key components in many industrial and scientific sectors.
In numerous domains polygonmeshes have become a de facto standard for model representation.
In practice meshes often have a number ofdefects and flaws that make them incompatible
with quality requirements of specific applications. Hence, repairingsuch defects
in order to achieve compatibility is a highly important task - in academic as
well as industrial applications. In this tutorial we first systematically analyze
typical application contexts together with their requirementsand issues, as well
as the various types of defects that typically play a role. Subsequently, we considerexisting
techniques to process, repair, and improve the structure, geometry, and topology
of imperfect meshes,aiming at making them appropriate to case-by-case requirements.
We present seminal works and key algorithms,discuss extensions and improvements,
and analyze the respective advantages and disadvantages depending onthe application
context. Furthermore, we outline directions where further research is particularly
important orpromising.

text: We design the geometrical shape of plasmonic nanostructures to achieve field
patterns with desired properties. For this, we combine Maxwell simulations and
automatic optimization techniques. By allowing variations of the geometrical shape,
which can be based on either boxes or arbitrary polygons, we maximize the desired
objective.

text: "During rescue scenarios it is indispensable to obtain an overview of the
situation. Unmanned aerial vehicles (UAVs) can gather the necessary information
in a fast and efficient way. This paper presents an approach for path planning
in 3D environments offering a solution to explore disaster areas including, e.g.,
partially or completely destroyed buildings. Using multiple UAVs decreases the
time needed to receive a complete overview if the problem of coordination and
task allocation is solved. We present an approach for the use of multiple UAVs.
The UAVs work in a distributed manner without any central coordination instance
and cover the exploration of terrains as well as goal-oriented path planning.
When using multiple UAVs redundant exploration is avoided through the use of inter-UAV-communication.
The approach is based on potential fields and uses the simplicity of the gradient
method to calculate paths for fast exploration of the terrain.\r\n"
