text: The hanging-drop network (HDN) is a technology platform based on a completely
open microfluidic network at the bottom of an inverted, surface-patterned substrate.
The platform is predominantly used for the formation, culturing, and interaction
of self-assembled spherical microtissues (spheroids) under precisely controlled
flow conditions. Here, we describe design, fabrication, and operation of microfluidic
hanging-drop networks.

text: Probabilistic programs extend classical imperative programs with real-valued
random variables and random branching. The most basic liveness property for such
programs is the termination property. The qualitative (aka almost-sure) termination
problem asks whether a given program program terminates with probability 1. While
ranking functions provide a sound and complete method for non-probabilistic programs,
the extension of them to probabilistic programs is achieved via ranking supermartingales
(RSMs). Although deep theoretical results have been established about RSMs, their
application to probabilistic programs with nondeterminism has been limited only
to programs of restricted control-flow structure. For non-probabilistic programs,
lexicographic ranking functions provide a compositional and practical approach
for termination analysis of real-world programs. In this work we introduce lexicographic
RSMs and show that they present a sound method for almost-sure termination of
probabilistic programs with nondeterminism. We show that lexicographic RSMs provide
a tool for compositional reasoning about almost-sure termination, and for probabilistic
programs with linear arithmetic they can be synthesized efficiently (in polynomial
time). We also show that with additional restrictions even asymptotic bounds on
expected termination time can be obtained through lexicographic RSMs. Finally,
we present experimental results on benchmarks adapted from previous work to demonstrate
the effectiveness of our approach.

text: Adventitious roots (AR) are de novo formed roots that emerge from any part
of the plant or from callus in tissue culture, except root tissue. The plant tissue
origin and the method by which they are induced determine the physiological properties
of emerged ARs. Hence, a standard method encompassing all types of AR does not
exist. Here we describe a method for the induction and analysis of AR that emerge
from the etiolated hypocotyl of dicot plants. The hypocotyl is formed during embryogenesis
and shows a determined developmental pattern which usually does not involve AR
formation. However, the hypocotyl shows propensity to form de novo roots under
specific circumstances such as removal of the root system, high humidity or flooding,
or during de-etiolation. The hypocotyl AR emerge from a pericycle-like cell layer
surrounding the vascular tissue of the central cylinder, which is reminiscent
to the developmental program of lateral roots. Here we propose an easy protocol
for in vitro hypocotyl AR induction from etiolated Arabidopsis seedlings.

text: Immunolocalization is a valuable tool for cell biology research that allows
to rapidly determine the localization and expression levels of endogenous proteins.
In plants, whole-mount in situ immunolocalization remains a challenging method,
especially in tissues protected by waxy layers and complex cell wall carbohydrates.
Here, we present a robust method for whole-mount in situ immunolocalization in
primary root meristems and lateral root primordia in Arabidopsis thaliana. For
good epitope preservation, fixation is done in an alkaline paraformaldehyde/glutaraldehyde
mixture. This fixative is suitable for detecting a wide range of proteins, including
integral transmembrane proteins and proteins peripherally attached to the plasma
membrane. From initiation until emergence from the primary root, lateral root
primordia are surrounded by several layers of differentiated tissues with a complex
cell wall composition that interferes with the efficient penetration of all buffers.
Therefore, immunolocalization in early lateral root primordia requires a modified
method, including a strong solvent treatment for removal of hydrophobic barriers
and a specific cocktail of cell wall-degrading enzymes. The presented method allows
for easy, reliable, and high-quality in situ detection of the subcellular localization
of endogenous proteins in primary and lateral root meristems without the need
of time-consuming crosses or making translational fusions to fluorescent proteins.
