text: Human cancer cells bear complex chromosome rearrangements that can be potential
drivers of cancer development. However, the molecular mechanisms underlying these
rearrangements have been unclear. Zhang et al. use a new technique combining live-cell
imaging and single-cell sequencing to demonstrate that chromosomes mis-segregated
to micronuclei frequently undergo chromothripsis-like rearrangements in the subsequent
cell cycle.

text: Previously, we identified the nucleoporin gp210/Nup210 as a critical regulator
of muscle and neuronal differentiation, but how this nucleoporin exerts its function
and whether it modulates nuclear pore complex (NPC) activity remain unknown. Here,
we show that gp210/Nup210 mediates muscle cell differentiation in vitro via its
conserved N-terminal domain that extends into the perinuclear space. Removal of
the C-terminal domain, which partially mislocalizes gp210/Nup210 away from NPCs,
efficiently rescues the differentiation defect caused by the knockdown of endogenous
gp210/Nup210. Unexpectedly, a gp210/Nup210 mutant lacking the NPC-targeting transmembrane
and C-terminal domains is sufficient for C2C12 myoblast differentiation. We demonstrate
that the endoplasmic reticulum (ER) stress-specific caspase cascade is exacerbated
during Nup210 depletion and that blocking ER stress-mediated apoptosis rescues
differentiation of Nup210-deficient cells. Our results suggest that the role of
gp210/Nup210 in cell differentiation is mediated by its large luminal domain,
which can act independently of NPC association and appears to play a pivotal role
in the maintenance of nuclear envelope/ER homeostasis.

text: Nuclear pore complexes (NPCs) are composed of several copies of ∼30 different
proteins called nucleoporins (Nups). NPCs penetrate the nuclear envelope (NE)
and regulate the nucleocytoplasmic trafficking of macromolecules. Beyond this
vital role, NPC components influence genome functions in a transport-independent
manner. Nups play an evolutionarily conserved role in gene expression regulation
that, in metazoans, extends into the nuclear interior. Additionally, in proliferative
cells, Nups play a crucial role in genome integrity maintenance and mitotic progression.
Here we discuss genome-related functions of Nups and their impact on essential
DNA metabolism processes such as transcription, chromosome duplication, and segregation.

text: Nucleoporins (Nups) are a family of proteins best known as the constituent
building blocks of nuclear pore complexes (NPCs), membrane-embedded channels that
mediate nuclear transport across the nuclear envelope. Recent evidence suggests
that several Nups have additional roles in controlling the activation and silencing
of developmental genes; however, the mechanistic details of these functions remain
poorly understood. Here, we show that depletion of Nup153 in mouse embryonic stem
cells (mESCs) causes the derepression of developmental genes and induction of
early differentiation. This loss of stem cell identity is not associated with
defects in the nuclear import of key pluripotency factors. Rather, Nup153 binds
around the transcriptional start site (TSS) of developmental genes and mediates
the recruitment of the polycomb-repressive complex 1 (PRC1) to a subset of its
target loci. Our results demonstrate a chromatin-associated role of Nup153 in
maintaining stem cell pluripotency by functioning in mammalian epigenetic gene
silencing.

text: Aging is associated with the decline of protein, cell, and organ function.
Here, we use an integrated approach to characterize gene expression, bulk translation,
and cell biology in the brains and livers of young and old rats. We identify 468
differences in protein abundance between young and old animals. The majority are
a consequence of altered translation output, that is, the combined effect of changes
in transcript abundance and translation efficiency. In addition, we identify 130
proteins whose overall abundance remains unchanged but whose sub-cellular localization,
phosphorylation state, or splice-form varies. While some protein-level differences
appear to be a generic property of the rats’ chronological age, the majority are
specific to one organ. These may be a consequence of the organ’s physiology or
the chronological age of the cells within the tissue. Taken together, our study
provides an initial view of the proteome at the molecular, sub-cellular, and organ
level in young and old rats.

text: Aging is a major risk factor for many human diseases, and in vitro generation
of human neurons is an attractive approach for modeling aging-related brain disorders.
However, modeling aging in differentiated human neurons has proved challenging.
We generated neurons from human donors across a broad range of ages, either by
iPSC-based reprogramming and differentiation or by direct conversion into induced
neurons (iNs). While iPSCs and derived neurons did not retain aging-associated
gene signatures, iNs displayed age-specific transcriptional profiles and revealed
age-associated decreases in the nuclear transport receptor RanBP17. We detected
an age-dependent loss of nucleocytoplasmic compartmentalization (NCC) in donor
fibroblasts and corresponding iNs and found that reduced RanBP17 impaired NCC
in young cells, while iPSC rejuvenation restored NCC in aged cells. These results
show that iNs retain important aging-related signatures, thus allowing modeling
of the aging process in vitro, and they identify impaired NCC as an important
factor in human aging.

text: 'Faint Lyα emitters become increasingly rarer toward the reionization epoch
(z ∼ 6–7). However, observations from a very large (∼5 deg2) Lyα narrow-band survey
at z = 6.6 show that this is not the case for the most luminous emitters, capable
of ionizing their own local bubbles. Here we present follow-up observations of
the two most luminous Lyα candidates in the COSMOS field: “MASOSA” and “CR7.”
We used X-SHOOTER, SINFONI, and FORS2 on the Very Large Telescope, and DEIMOS
on Keck, to confirm both candidates beyond any doubt. We find redshifts of z =
6.541 and z = 6.604 for “MASOSA” and “CR7,” respectively. MASOSA has a strong
detection in Lyα with a line width of 386 ± 30 km s−1 (FWHM) and with very high
EW0 (>200 Å), but undetected in the continuum, implying very low stellar mass
and a likely young, metal-poor stellar population. “CR7,” with an observed Lyα
luminosity of 1043.92±0.05 erg s−1 is the most luminous Lyα emitter ever found
at z > 6 and is spatially extended (∼16 kpc). “CR7” reveals a narrow Lyα line
with 266 ± 15 km s−1 FWHM, being detected in the near-infrared (NIR) (rest-frame
UV; β = −2.3 ± 0.1) and in IRAC/Spitzer. We detect a narrow He II 1640 Å emission
line (6σ, FWHM = 130 ± 30 km s−1 ) in CR7 which can explain the clear excess seen
in the J-band photometry (EW0 ∼ 80 Å). We find no other emission lines from the
UV to the NIR in our X-SHOOTER spectra (He II/O III] 1663 Å > 3 and He II/C III]
1908 Å > 2.5). We conclude that CR7 is best explained by a combination of a PopIII-like
population, which dominates the rest-frame UV and the nebular emission, and a
more normal stellar population, which presumably dominates the mass. Hubble Space
Telescope/WFC3 observations show that the light is indeed spatially separated
between a very blue component, coincident with Lyα and He II emission, and two
red components (∼5 kpc away), which dominate the mass. Our findings are consistent
with theoretical predictions of a PopIII wave, with PopIII star formation migrating
away from the original sites of star formation.'

text: CR7 is the brightest z = 6.6 Ly α emitter (LAE) known to date, and spectroscopic
follow-up by Sobral et al. suggests that CR7 might host Population (Pop) III stars.
We examine this interpretation using cosmological hydrodynamical simulations.
Several simulated galaxies show the same ‘Pop III wave’ pattern observed in CR7.
However, to reproduce the extreme CR7 Ly α/He II1640 line luminosities (Lα/HeII)
a top-heavy initial mass function and a massive ( ≳ 107 M⊙) Pop III burst with
age ≲ 2 Myr are required. Assuming that the observed properties of Ly α and He II
emission are typical for Pop III, we predict that in the COSMOS/UDS/SA22 fields,
14 out of the 30 LAEs at z = 6.6 with Lα > 1043.3 erg s−1 should also host Pop
III stars producing an observable LHeII≳1042.7ergs−1. As an alternate explanation,
we explore the possibility that CR7 is instead powered by accretion on to a direct
collapse black hole. Our model predicts Lα, LHeII, and X-ray luminosities that
are in agreement with the observations. In any case, the observed properties of
CR7 indicate that this galaxy is most likely powered by sources formed from pristine
gas. We propose that further X-ray observations can distinguish between the two
above scenarios.

text: 'We present results from the largest contiguous narrow-band survey in the
near-infrared. We have used the wide-field infrared camera/Canada–France–Hawaii
Telescope and the lowOH2 filter (1.187 ± 0.005 μm) to survey ≈10 deg2 of contiguous
extragalactic sky in the SA22 field. A total of ∼6000 candidate emission-line
galaxies are found. We use deep ugrizJK data to obtain robust photometric redshifts.
We combine our data with the High-redshift(Z) Emission Line Survey (HiZELS), explore
spectroscopic surveys (VVDS, VIPERS) and obtain our own spectroscopic follow-up
with KMOS, FMOS and MOSFIRE to derive large samples of high-redshift emission-line
selected galaxies: 3471 Hα emitters at z = 0.8, 1343 [O III] + Hβ emitters at
z = 1.4 and 572 [O II] emitters at z = 2.2. We probe comoving volumes of >106
Mpc3 and find significant overdensities, including an 8.5σ (spectroscopically
confirmed) overdensity of Hα emitters at z = 0.81. We derive Hα, [O III] + Hβ
and [O II] luminosity functions at z = 0.8, 1.4, 2.2, respectively, and present
implications for future surveys such as Euclid. Our uniquely large volumes/areas
allow us to subdivide the samples in thousands of randomized combinations of areas
and provide a robust empirical measurement of sample/cosmic variance. We show
that surveys for star-forming/emission-line galaxies at a depth similar to ours
can only overcome cosmic-variance (errors <10 per cent) if they are based on volumes
>5 × 105 Mpc3; errors on L* and ϕ* due to sample (cosmic) variance on surveys
probing ∼104 and ∼105 Mpc3 are typically very high: ∼300 and ∼40–60 per cent,
respectively.'

text: Using wide-field narrow-band surveys, we provide a new measurement of the
z = 6.6 Lymanα emitter (LAE) luminosity function (LF), which constraints the bright
end for the first time. We use a combination of archival narrow-band NB921 data
in UDS and new NB921 measurements in SA22 and COSMOS/UltraVISTA, all observed
with the Subaru telescope, with a total area of ∼5 deg2. We exclude lower redshift
interlopers by using broad-band optical and near-infrared photometry and also
exclude three supernovae with data split over multiple epochs. Combining the UDS
and COSMOS samples, we find no evolution of the bright end of the Lyα LF between
z = 5.7 and 6.6, which is supported by spectroscopic follow-up, and conclude that
sources with Himiko-like luminosity are not as rare as previously thought, with
number densities of ∼1.5 × 10−5 Mpc−3. Combined with our wide-field SA22 measurements,
our results indicate a non-Schechter-like bright end of the LF at z = 6.6 and
a different evolution of observed faint and bright LAEs, overcoming cosmic variance.
This differential evolution is also seen in the spectroscopic follow-up of UV-selected
galaxies and is now also confirmed for LAEs, and we argue that it may be an effect
of reionization. Using a toy model, we show that such differential evolution of
the LF is expected, since brighter sources are able to ionize their surroundings
earlier, such that Lyα photons are able to escape. Our targets are excellent candidates
for detailed follow-up studies and provide the possibility to give a unique view
on the earliest stages in the formation of galaxies and reionization process.

text: "We study multiple keyword sponsored search auctions with budgets. Each keyword
has multiple ad slots with a click-through rate. The bidders have additive valuations,
which are linear in the click-through rates, and budgets, which are restricting
their overall payments. Additionally, the number of slots per keyword assigned
to a bidder is bounded.\r\n\r\nWe show the following results: (1) We give the
first mechanism for multiple keywords, where click-through rates differ among
slots. Our mechanism is incentive compatible in expectation, individually rational
in expectation, and Pareto optimal. (2) We study the combinatorial setting, where
each bidder is only interested in a subset of the keywords. We give an incentive
compatible, individually rational, Pareto-optimal, and deterministic mechanism
for identical click-through rates. (3) We give an impossibility result for incentive
compatible, individually rational, Pareto-optimal, and deterministic mechanisms
for bidders with diminishing marginal valuations."

text: We study individual rational, Pareto-optimal, and incentive compatible mechanisms
for auctions with heterogeneous items and budget limits. We consider settings
with multiunit demand and additive valuations. For single-dimensional valuations
we prove a positive result for randomized mechanisms, and a negative result for
deterministic mechanisms. While the positive result allows for private budgets,
the negative result is for public budgets. For multidimensional valuations and
public budgets we prove an impossibility result that applies to deterministic
and randomized mechanisms. Taken together this shows the power of randomization
in certain settings with heterogeneous items, but it also shows its limitations.

text: Auctions are widely used on the Web. Applications range from sponsored search
to platforms such as eBay. In these and in many other applications the auctions
in use are single-/multi-item auctions with unit demand. The main drawback of
standard mechanisms for this type of auctions, such as VCG and GSP, is the limited
expressiveness that they offer to the bidders. The General Auction Mechanism (GAM)
of Aggarwal et al. [2009] takes a first step toward addressing the problem of
limited expressiveness by computing a bidder optimal, envy-free outcome for linear
utility functions with identical slopes and a single discontinuity per bidder-item
pair. We show that in many practical situations this does not suffice to adequately
model the preferences of the bidders, and we overcome this problem by presenting
the first mechanism for piecewise linear utility functions with nonidentical slopes
and multiple discontinuities. Our mechanism runs in polynomial time. Like GAM
it is incentive compatible for inputs that fulfill a certain nondegeneracy assumption,
but our requirement is more general than the requirement of GAM. For discontinuous
utility functions that are nondegenerate as well as for continuous utility functions
the outcome of our mechanism is a competitive equilibrium. We also show how our
mechanism can be used to compute approximately bidder optimal, envy-free outcomes
for a general class of continuous utility functions via piecewise linear approximation.
Finally, we prove hardness results for even more expressive settings.

text: "Ad exchanges are an emerging platform for trading advertisement slots on
the web with billions of dollars revenue per year. Every time a user visits a
web page, the publisher of that web page can ask an ad exchange to auction off
the ad slots on this page to determine which advertisements are shown at which
price. Due to the high volume of traffic, ad networks typically act as mediators
for individual advertisers at ad exchanges. If multiple advertisers in an ad network
are interested in the ad slots of the same auction, the ad network might use a
“local” auction to resell the obtained ad slots among its advertisers.\r\n\r\nIn
this work we want to deepen the theoretical understanding of these new markets
by analyzing them from the viewpoint of combinatorial auctions. Prior work studied
mostly single-item auctions, while we allow the advertisers to express richer
preferences over multiple items. We develop a game-theoretic model for the entanglement
of the central auction at the ad exchange with the local auctions at the ad networks.
We consider the incentives of all three involved parties and suggest a three-party
competitive equilibrium, an extension of the Walrasian equilibrium that ensures
envy-freeness for all participants. We show the existence of a three-party competitive
equilibrium and a polynomial-time algorithm to find one for gross-substitute bidder
valuations."

text: "Combinatorial auctions (CA) are a well-studied area in algorithmic mechanism
design. However, contrary to the standard model, empirical studies suggest that
a bidder’s valuation often does not depend solely on the goods assigned to him.
For instance, in adwords auctions an advertiser might not want his ads to be displayed
next to his competitors’ ads. In this paper, we propose and analyze several natural
graph-theoretic models that incorporate such negative externalities, in which
bidders form a directed conflict graph with maximum out-degree Δ. We design algorithms
and truthful mechanisms for social welfare maximization that attain approximation
ratios depending on Δ.\r\n\r\nFor CA, our results are twofold: (1) A lottery that
eliminates conflicts by discarding bidders/items independent of the bids. It allows
to apply any truthful \U0001D6FC-approximation mechanism for conflict-free valuations
and yields an \U0001D4AA(\U0001D6FCΔ)-approximation mechanism. (2) For fractionally
sub-additive valuations, we design a rounding algorithm via a novel combination
of a semi-definite program and a linear program, resulting in a cone program;
the approximation ratio is \U0001D4AA((ΔloglogΔ)/logΔ). The ratios are almost
optimal given existing hardness results.\r\n\r\nFor adwords auctions, we present
several algorithms for the most relevant scenario when the number of items is
small. In particular, we design a truthful mechanism with approximation ratio
\U0001D45C(Δ) when the number of items is only logarithmic in the number of bidders."

text: "Recently we presented the first algorithm for maintaining the set of nodes
reachable from a source node in a directed graph that is modified by edge deletions
with \U0001D45C(\U0001D45A\U0001D45B) total update time, where \U0001D45A is the
number of edges and \U0001D45B is the number of nodes in the graph [Henzinger
et al. STOC 2014]. The algorithm is a combination of several different algorithms,
each for a different \U0001D45A vs. \U0001D45B trade-off. For the case of \U0001D45A=Θ(\U0001D45B1.5)
the running time is \U0001D442(\U0001D45B2.47), just barely below \U0001D45A\U0001D45B=Θ(\U0001D45B2.5).
In this paper we simplify the previous algorithm using new algorithmic ideas and
achieve an improved running time of \U0001D442̃ (min(\U0001D45A7/6\U0001D45B2/3,\U0001D45A3/4\U0001D45B5/4+\U0001D45C(1),\U0001D45A2/3\U0001D45B4/3+\U0001D45C(1)+\U0001D45A3/7\U0001D45B12/7+\U0001D45C(1))).
This gives, e.g., \U0001D442(\U0001D45B2.36) for the notorious case \U0001D45A=Θ(\U0001D45B1.5).
We obtain the same upper bounds for the problem of maintaining the strongly connected
components of a directed graph undergoing edge deletions. Our algorithms are correct
with high probabililty against an oblivious adversary."

text: "We present faster algorithms for computing the 2-edge and 2-vertex strongly
connected components of a directed graph. While in undirected graphs the 2-edge
and 2-vertex connected components can be found in linear time, in directed graphs
with m edges and n vertices only rather simple O(m n)-time algorithms were known.
We use a hierarchical sparsification technique to obtain algorithms that run in
time \U0001D442(\U0001D45B2). For 2-edge strongly connected components our algorithm
gives the first running time improvement in 20 years. Additionally we present
an \U0001D442(\U0001D45A2/log\U0001D45B)-time algorithm for 2-edge strongly connected
components, and thus improve over the O(m n) running time also when \U0001D45A=\U0001D442(\U0001D45B).
Our approach extends to k-edge and k-vertex strongly connected components for
any constant k with a running time of \U0001D442(\U0001D45B2log\U0001D45B) for
k-edge-connectivity and \U0001D442(\U0001D45B3) for k-vertex-connectivity."

text: "Ad exchanges are becoming an increasingly popular way to sell advertisement
slots on the internet. An ad exchange is basically a spot market for ad impressions.
A publisher who has already signed contracts reserving advertisement impressions
on his pages can choose between assigning a new ad impression for a new page view
to a contracted advertiser or to sell it at an ad exchange. This leads to an online
revenue maximization problem for the publisher. Given a new impression to sell
decide whether (a) to assign it to a contracted advertiser and if so to which
one or (b) to sell it at the ad exchange and if so at which reserve price. We
make no assumptions about the distribution of the advertiser valuations that participate
in the ad exchange and show that there exists a simple primal-dual based online
algorithm, whose lower bound for the revenue converges to \U0001D445\U0001D434\U0001D437\U0001D44B+\U0001D445\U0001D434(1−1/\U0001D452),
where \U0001D445\U0001D434\U0001D437\U0001D44B is the revenue that the optimum
algorithm achieves from the ad exchange and \U0001D445\U0001D434 is the revenue
that the optimum algorithm achieves from the contracted advertisers."
