text: Quantum many-body systems can have phase transitions even at zero temperature;
fluctuations arising from Heisenbergĝ€™s uncertainty principle, as opposed to
thermal effects, drive the system from one phase to another. Typically, during
the transition the relative strength of two competing terms in the systemĝ€™s
Hamiltonian changes across a finite critical value. A well-known example is the
Mottĝ€" Hubbard quantum phase transition from a superfluid to an insulating
phase, which has been observed for weakly interacting bosonic atomic gases. However,
for strongly interacting quantum systems confined to lower-dimensional geometry,
a novel type of quantum phase transition may be induced and driven by an arbitrarily
weak perturbation to the Hamiltonian. Here we observe such an effectĝ€"the
sineĝ€"Gordon quantum phase transition from a superfluid Luttinger liquid
to a Mott insulatorĝ€ "in a one-dimensional quantum gas of bosonic caesium
atoms with tunable interactions. For sufficiently strong interactions, the transition
is induced by adding an arbitrarily weak optical lattice commensurate with the
atomic granularity, which leads to immediate pinning of the atoms. We map out
the phase diagram and find that our measurements in the strongly interacting regime
agree well with a quantum field description based on the exactly solvable sineĝ€"Gordon
model. We trace the phase boundary all the way to the weakly interacting regime,
where we find good agreement with the predictions of the one-dimensional Boseĝ€"Hubbard
model. Our results open up the experimental study of quantum phase transitions,
criticality and transport phenomena beyond Hubbard-type models in the context
of ultracold gases.

text: Eukaryotic cytosine methylation represses transcription but also occurs in
the bodies of active genes, and the extent of methylation biology conservation
is unclear. We quantified DNA methylation in 17 eukaryotic genomes and found that
gene body methylation is conserved between plants and animals, whereas selective
methylation of transposons is not. We show that methylation of plant transposons
in the CHG context extends to green algae and that exclusion of histone H2A.Z
from methylated DNA is conserved between plants and animals, and we present evidence
for RNA-directed DNA methylation of fungal genes. Our data demonstrate that extant
DNA methylation systems are mosaics of conserved and derived features, and indicate
that gene body methylation is an ancient property of eukaryotic genomes.

text: 'Cytosine methylation silences transposable elements in plants, vertebrates,
and fungi but also regulates gene expression. Plant methylation is catalyzed by
three families of enzymes, each with a preferred sequence context: CG, CHG (H
= A, C, or T), and CHH, with CHH methylation targeted by the RNAi pathway. Arabidopsis
thaliana endosperm, a placenta-like tissue that nourishes the embryo, is globally
hypomethylated in the CG context while retaining high non-CG methylation. Global
methylation dynamics in seeds of cereal crops that provide the bulk of human nutrition
remain unknown. Here, we show that rice endosperm DNA is hypomethylated in all
sequence contexts. Non-CG methylation is reduced evenly across the genome, whereas
CG hypomethylation is localized. CHH methylation of small transposable elements
is increased in embryos, suggesting that endosperm demethylation enhances transposon
silencing. Genes preferentially expressed in endosperm, including those coding
for major storage proteins and starch synthesizing enzymes, are frequently hypomethylated
in endosperm, indicating that DNA methylation is a crucial regulator of rice endosperm
biogenesis. Our data show that genome-wide reshaping of seed DNA methylation is
conserved among angiosperms and has a profound effect on gene expression in cereal
crops.'

text: We present ABC, a software tool for automatically computing symbolic upper
bounds on the number of iterations of nested program loops. The system combines
static analysis of programs with symbolic summation techniques to derive loop
invariant relations between program variables. Iteration bounds are obtained from
the inferred invariants, by replacing variables with bounds on their greatest
values. We have successfully applied ABC to a large number of examples. The derived
symbolic bounds express non-trivial polynomial relations over loop variables.
We also report on results to automatically infer symbolic expressions over harmonic
numbers as upper bounds on loop iteration counts.

text: We address the problem of localizing homology classes, namely, finding the
cycle representing a given class with the most concise geometric measure. We focus
on the volume measure, that is, the 1-norm of a cycle. Two main results are presented.
First, we prove the problem is NP-hard to approximate within any constant factor.
Second, we prove that for homology of dimension two or higher, the problem is
NP-hard to approximate even when the Betti number is O(1). A side effect is the
inapproximability of the problem of computing the nonbounding cycle with the smallest
volume, and computing cycles representing a homology basis with the minimal total
volume. We also discuss other geometric measures (diameter and radius) and show
their disadvantages in homology localization. Our work is restricted to homology
over the ℤ2 field.

text: The nuclear envelope (NE) is a highly regulated membrane barrier that separates
the nucleus from the cytoplasm in eukaryotic cells. It contains a large number
of different proteins that have been implicated in chromatin organization and
gene regulation. Although the nuclear membrane enables complex levels of gene
expression, it also poses a challenge when it comes to cell division. To allow
access of the mitotic spindle to chromatin, the nucleus of metazoans must completely
disassemble during mitosis, generating the need to re-establish the nuclear compartment
at the end of each cell division. Here, I summarize our current understanding
of the dynamic remodeling of the NE during the cell cycle.

text: Nuclear pore complexes (NPCs) serve as transport channels across the nuclear
membrane, a double lipid bilayer that physically separates the nucleoplasm and
cytoplasm of eukaryotic cells. New evidence suggests that the multiprotein nuclear
pores also play a role in chromatin organization and gene expression. Given the
importance of NPC function, it is not surprising that a growing list of human
diseases and developmental defects have been linked to its malfunction. In order
to fully understand the functional repertoire of NPCs and their essential role
for nuclear organization, it is critical to determine the sequence of events that
lead to the formation of nuclear pores. This is particularly relevant since NPC
number, and possibly composition, are tightly linked to metabolic activity. Most
of our knowledge is derived from NPC formation that occurs in dividing cells at
the end of mitosis when the nuclear envelope (NE) and NPCs reform from disassembled
precursors. However, NPC assembly also takes place during interphase into an intact
NE. Importantly, this process is not restricted to dividing cells but also occurs
during cell differentiation. Here, we will review aspects unique to this process,
namely the regulation of nuclear expansion and the mechanisms of fusion between
the outer and inner nuclear membranes. We will then discuss conserved and diverging
mechanisms between post-mitotic and interphase assembly of the proteinaceous structure
in light of recently published data.

text: In metazoa, nuclear pore complexes (NPCs) assemble from disassembled precursors
into a reforming nuclear envelope (NE) at the end of mitosis and into growing
intact NEs during interphase. Here, we show via RNAi-mediated knockdown that ELYS,
a nucleoporin critical for the recruitment of the essential Nup107/160 complex
to chromatin, is required for NPC assembly at the end of mitosis but not during
interphase. Conversely, the transmembrane nucleoporin POM121 is critical for the
incorporation of the Nup107/160 complex into new assembly sites specifically during
interphase. Strikingly, recruitment of the Nup107/160 complex to an intact NE
involves a membrane curvature-sensing domain of its constituent Nup133, which
is not required for postmitotic NPC formation. Our results suggest that in organisms
with open mitosis, NPCs assemble via two distinct mechanisms to accommodate cell
cycle-dependent differences in NE topology.

text: Nuclear pore complexes have recently been shown to play roles in gene activation;
however their potential involvement in metazoan transcription remains unclear.
Here we show that the nucleoporins Sec13, Nup98, and Nup88, as well as a group
of FG-repeat nucleoporins, bind to the Drosophila genome at functionally distinct
loci that often do not represent nuclear envelope contact sites. Whereas Nup88
localizes to silent loci, Sec13, Nup98, and a subset of FG-repeat nucleoporins
bind to developmentally regulated genes undergoing transcription induction. Strikingly,
RNAi-mediated knockdown of intranuclear Sec13 and Nup98 specifically inhibits
transcription of their target genes and prevents efficient reactivation of transcription
after heat shock, suggesting an essential role of NPC components in regulating
complex gene expression programs of multicellular organisms.

text: Ferroelectric ceramic materials have a wide range of applications because
of their piezoelectric and pyroelectric properties. One of their most important
physical properties is the specific heat. In this study, the specific heats of
a series of lead-zirconate-titanate (PZT) compositions in the vicinity of the
morphotropic phase boundary (MPB) were measured. The temperature range was from
1.8 to 300 K. It is believed that these are the lowest temperature measurements
ever made on PZT. Differences between the specific heats of the different compositions

The results are useful in computing design parameters for technical devices.

text: Ferroelectric ceramic materials have a wide range of applications because
of their piezoelectric and pyroelectric properties. One of their most important
physical properties is the specific heat. In this study, the specific heats of
a series of lead-zirconate-titanate (PZT) compositions in the vicinity of the
morphotropic phase boundary (MPB) were measured. The temperature range was from
1.8 to 300 K. It is believed that these are the lowest temperature measurements
ever made on PZT. Differences between the specific heats of the different compositions
were very small. However, the calculated Debye temperatures were slightly different.
The results are useful in computing design parameters for technical devices.

text: "Inspired by online ad allocation, we study online stochastic packing integer
programs from theoretical and practical standpoints. We first present a near-optimal
online algorithm for a general class of packing integer programs which model various
online resource allocation problems including online variants of routing, ad allocations,
generalized assignment, and combinatorial auctions. As our main theoretical result,
we prove that a simple dual training-based algorithm achieves a (1 − o(1))-approximation
guarantee in the random order stochastic model. This is a significant improvement
over logarithmic or constant-factor approximations for the adversarial variants
of the same problems (e.g. factor 1−1\U0001D452 for online ad allocation, and
log(m) for online routing). We then focus on the online display ad allocation
problem and study the efficiency and fairness of various training-based and online
allocation algorithms on data sets collected from real-life display ad allocation
system. Our experimental evaluation confirms the effectiveness of training-based
algorithms on real data sets, and also indicates an intrinsic trade-off between
fairness and efficiency."

text: Starting with two models fifty years ago, the discrete marriage game [1] and
the continuous assignment game [2], the study of stable matchings has evolved
into a rich theory with applications in many areas. Most notably, it has lead
to a number of truthful mechanisms that have seen a recent rejuvenation in the
context of sponsored search. In this paper we survey the history of these problems
and provide several links to ongoing research in the field.

text: Two-sided matching markets play a prominent role in economic theory. A prime
example of such a market is the sponsored search market where $n$ advertisers
compete for the assignment of one of $k$ sponsored search results, also known
as ``slots'', for certain keywords they are interested in. Here, as in other markets
of that kind, market equilibria correspond to stable matchings. In this paper,
we show how to modify Kuhn's Hungarian Method (Kuhn, 1955) so that it finds an
optimal stable matching between advertisers and advertising slots in settings
with generalized linear utilities, per-bidder-item reserve prices, and per-bidder-item
maximum prices. The only algorithm for this problem presented so far (Aggarwal
et al., 2009) requires the market to be in ''general position''. We do not make
this assumption.

text: "Suppose you buy a new laptop and, simply because you like it so much, you
recommend it to friends, encouraging them to purchase it as well. What would be
an adequate price for the vendor of the laptop to pay for your recommendation?\r\n\r\nPersonal
recommendations like this are of considerable commercial interest, but unlike
in sponsored search auctions there can be no truthful prices. Despite this \"lack
of truthfulness\" the vendor of the product might still decide to pay you for
recommendation e.g. because she wants to (i) provide you with an additional incentive
to actually recommend her or to (ii) increase your satisfaction and/or brand loyalty.
This leads us to investigate a pricing scheme based on the Shapley value [5] that
satisfies certain \"axioms of fairness\". We find that it is vulnerable to manipulations
and show how to overcome these difficulties using the anonymity-proof Shapley
value of [4]."

text: Over the last years the h-index has gained popularity as a measure for comparing
the impact of scientists. We investigate if ranking according to the h-index is
stable with respect to (i) different choices of citation databases, (ii) normalizing
citation counts by the number of authors or by removing self-citations, (iii)
small amounts of noise created by randomly removing citations or publications
and (iv) small changes in the definition of the index. In experiments for 5,283
computer scientists and 1,354 physicists we show that although the ranking of
the h-index is stable under most of these changes, it is unstable when different
databases are used. Therefore, comparisons based on the h-index should only be
trusted when the rankings of multiple citation databases agree.

text: A new method was developed for the quantitative analysis of steryl glycosides
in biodiesel (fatty acid methyl esters). This method is much more sensitive than
existing methods and has minimum limits of quantification of 50 μg/kg, compared
to previously published minimum limits of quantification of about 15 mg/kg. The
analysis is based on gas chromatography–mass spectroscopy determination of simple
pre-treated and silylated samples via single ion monitoring at 147, 204, 217 m/z,
which are specific ions for the silylated sugar moiety. Quantification was carried
out using cholesteryl β-d-glucopyranoside as internal standard. The modified synthesis
and purification of the internal standard is also presented as well as the characterization
by NMR and mass spectroscopy. The advantage of the method compared with other
approaches is the simplified sample preparation avoiding extra pre-treatment steps
coupled with complete derivatization of the sugar hydroxyl groups by using N,O-bis(trimethylsilyl)acetamide
with 5% trimethylchlorosilane as derivatization reagent. On the given conditions
high recovery rates ≥89% can be obtained. Evaluation of lab specific variance
and intermediate precision underline the robustness of the method which will be
further assessed by Round robin tests.
