text: Playing table tennis is a difficult task for robots, especially due to their
limitations of acceleration. A key bottleneck is the amount of time needed to
reach the desired hitting position and velocity of the racket for returning the
incoming ball. Here, it often does not suffice to simply extrapolate the ball's
trajectory after the opponent returns it but more information is needed. Humans
are able to predict the ball's trajectory based on the opponent's moves and, thus,
have a considerable advantage. Hence, we propose to incorporate an anticipation
system into robot table tennis players, which enables the robot to react earlier
while the opponent is performing the striking movement. Based on visual observation
of the opponent's racket movement, the robot can predict the aim of the opponent
and adjust its movement generation accordingly. The policies for deciding how
and when to react are obtained by reinforcement learning. We conduct experiments
with an existing robot player to show that the learned reaction policy can significantly
improve the performance of the overall system.

text: 'We consider 2-player games played on a finite state space for an infinite
number of rounds. The games are concurrent: in each round, the two players (player
1 and player 2) choose their moves inde- pendently and simultaneously; the current
state and the two moves determine the successor state. We study concurrent games
with ω-regular winning conditions specified as parity objectives. We consider
the qualitative analysis problems: the computation of the almost-sure and limit-sure
winning set of states, where player 1 can ensure to win with probability 1 and
with probability arbitrarily close to 1, respec- tively. In general the almost-sure
and limit-sure winning strategies require both infinite-memory as well as infinite-precision
(to describe probabilities). We study the bounded-rationality problem for qualitative
analysis of concurrent parity games, where the strategy set for player 1 is restricted
to bounded-resource strategies. In terms of precision, strategies can be deterministic,
uniform, finite-precision or infinite- precision; and in terms of memory, strategies
can be memoryless, finite-memory or infinite-memory. We present a precise and
complete characterization of the qualitative winning sets for all combinations
of classes of strategies. In particular, we show that uniform memoryless strategies
are as powerful as finite-precision infinite-memory strategies, and infinite-precision
memoryless strategies are as power- ful as infinite-precision finite-memory strategies.
We show that the winning sets can be computed in O(n2d+3) time, where n is the
size of the game structure and 2d is the number of priorities (or colors), and
our algorithms are symbolic. The membership problem of whether a state belongs
to a winning set can be decided in NP ∩ coNP. While this complexity is the same
as for the simpler class of turn-based parity games, where in each state only
one of the two players has a choice of moves, our algorithms, that are obtained
by characterization of the winning sets as μ-calculus formulas, are considerably
more involved than those for turn-based games.'

text: 'Turn-based stochastic games and its important subclass Markov decision processes
(MDPs) provide models for systems with both probabilistic and nondeterministic
behaviors. We consider turn-based stochastic games with two classical quantitative
objectives: discounted-sum and long-run average objectives. The game models and
the quantitative objectives are widely used in probabilistic verification, planning,
optimal inventory control, network protocol and performance analysis. Games and
MDPs that model realistic systems often have very large state spaces, and probabilistic
abstraction techniques are necessary to handle the state-space explosion. The
commonly used full-abstraction techniques do not yield space-savings for systems
that have many states with similar value, but does not necessarily have similar
transition structure. A semi-abstraction technique, namely Magnifying-lens abstractions
(MLA), that clusters states based on value only, disregarding differences in their
transition relation was proposed for qualitative objectives (reachability and
safety objectives). In this paper we extend the MLA technique to solve stochastic
games with discounted-sum and long-run average objectives. We present the MLA
technique based abstraction-refinement algorithm for stochastic games and MDPs
with discounted-sum objectives. For long-run average objectives, our solution
works for all MDPs and a sub-class of stochastic games where every state has the
same value. '

text: 'We consider Markov decision processes (MDPs) with ω-regular specifications
given as parity objectives. We consider the problem of computing the set of almost-sure
winning states from where the objective can be ensured with probability 1. The
algorithms for the computation of the almost-sure winning set for parity objectives
iteratively use the solutions for the almost-sure winning set for Büchi objectives
(a special case of parity objectives). Our contributions are as follows: First,
we present the first subquadratic symbolic algorithm to compute the almost-sure
winning set for MDPs with Büchi objectives; our algorithm takes O(nm) symbolic
steps as compared to the previous known algorithm that takes O(n 2) symbolic steps,
where n is the number of states and m is the number of edges of the MDP. In practice
MDPs often have constant out-degree, and then our symbolic algorithm takes O(nn) symbolic
steps, as compared to the previous known O(n 2) symbolic steps algorithm. Second,
we present a new algorithm, namely win-lose algorithm, with the following two
properties: (a) the algorithm iteratively computes subsets of the almost-sure
winning set and its complement, as compared to all previous algorithms that discover
the almost-sure winning set upon termination; and (b) requires O(nK) symbolic
steps, where K is the maximal number of edges of strongly connected components
(scc’s) of the MDP. The win-lose algorithm requires symbolic computation of scc’s.
Third, we improve the algorithm for symbolic scc computation; the previous known
algorithm takes linear symbolic steps, and our new algorithm improves the constants
associated with the linear number of steps. In the worst case the previous known
algorithm takes 5·n symbolic steps, whereas our new algorithm takes 4 ·n symbolic
steps.'

text: 'Games played on graphs provide the mathematical framework to analyze several
important problems in computer science as well as mathematics, such as the synthesis
problem of Church, model checking of open reactive systems and many others. On
the basis of mode of interaction of the players these games can be classified
as follows: (a) turn-based (players make moves in turns); and (b) concurrent (players
make moves simultaneously). On the basis of the information available to the players
these games can be classified as follows: (a) perfect-information (players have
perfect view of the game); and (b) partial-information (players have partial view
of the game). In this talk we will consider all these classes of games with reachability
objectives, where the goal of one player is to reach a set of target vertices
of the graph, and the goal of the opponent player is to prevent the player from
reaching the target. We will survey the results for various classes of games,
and the results range from linear time decision algorithms to EXPTIME-complete
problems to undecidable problems.'

text: This paper presents a method to create a model of an articulated object using
the planar motion in an initialization video. The model consists of rigid parts
connected by points of articulation. The rigid parts are described by the positions
of salient feature-points tracked throughout the video. Following a filtering
step that identifies points that belong to different objects, rigid parts are
found by a grouping process in a graph pyramid. Valid articulation points are
selected by verifying multiple hypotheses for each pair of parts.

text: Nuclear pore complexes (NPCs) assemble at the end of mitosis during nuclear
envelope (NE) reformation and into an intact NE as cells progress through interphase.
Although recent studies have shown that NPC formation occurs by two different
molecular mechanisms at two distinct cell cycle stages, little is known about
the molecular players that mediate the fusion of the outer and inner nuclear membranes
to form pores. In this paper, we provide evidence that the transmembrane nucleoporin
(Nup), POM121, but not the Nup107–160 complex, is present at new pore assembly
sites at a time that coincides with inner nuclear membrane (INM) and outer nuclear
membrane (ONM) fusion. Overexpression of POM121 resulted in juxtaposition of the
INM and ONM. Additionally, Sun1, an INM protein that is known to interact with
the cytoskeleton, was specifically required for interphase assembly and localized
with POM121 at forming pores. We propose a model in which POM121 and Sun1 interact
transiently to promote early steps of interphase NPC assembly.

text: As the gatekeepers of the eukaryotic cell nucleus, nuclear pore complexes
(NPCs) mediate all molecular trafficking between the nucleoplasm and the cytoplasm.
In recent years, transport-independent functions of NPC components, nucleoporins,
have been identified including roles in chromatin organization and gene regulation.
Here, we summarize our current view of the NPC as a dynamic hub for the integration
of chromatin regulation and nuclear trafficking and discuss the functional interplay
between nucleoporins and the nuclear genome.

text: Eukaryotic cell function depends on the physical separation of nucleoplasmic
and cytoplasmic components by the nuclear envelope (NE). Molecular communication
between the two compartments involves active, signal-mediated trafficking, a function
that is exclusively performed by nuclear pore complexes (NPCs). The individual
NPC components and the mechanisms that are involved in nuclear trafficking are
well documented and have become textbook knowledge. However, in addition to their
roles as nuclear gatekeepers, NPC components-nucleoporins-have been shown to have
critical roles in chromatin organization and gene regulation. These findings have
sparked new enthusiasm to study the roles of this multiprotein complex in nuclear
organization and explore novel functions that in some cases appear to go beyond
a role in transport. Here, we discuss our present view of NPC biogenesis, which
is tightly linked to proper cell cycle progression and cell differentiation. In
addition, we summarize new data suggesting that NPCs represent dynamic hubs for
the integration of gene regulation and nuclear transport processes.

text: Particle beams are important tools for probing atomic and molecular interactions.
Here we demonstrate that particle beams also offer a unique opportunity to investigate
interactions in macroscopic systems, such as granular media. Motivated by recent
experiments on streams of grains that exhibit liquid-like breakup into droplets,
we use molecular dynamics simulations to investigate the evolution of a dense
stream of macroscopic spheres accelerating out of an opening at the bottom of
a reservoir. We show how nanoscale details associated with energy dissipation
during collisions modify the stream\'s macroscopic behavior. We find that inelastic
collisions collimate the stream, while the presence of short-range attractive
interactions drives structure formation. Parameterizing the collision dynamics
by the coefficient of restitution (i.e., the ratio of relative velocities before
and after impact) and the strength of the cohesive interaction, we map out a spectrum
of behaviors that ranges from gaslike jets in which all grains drift apart to
liquid-like streams that break into large droplets containing hundreds of grains.
We also find a new, intermediate regime in which small aggregates form by capture
from the gas phase, similar to what can be observed in molecular beams. Our results
show that nearly all aspects of stream behavior are closely related to the velocity
gradient associated with vertical free fall. Led by this observation, we propose
a simple energy balance model to explain the droplet formation process. The qualitative
as well as many quantitative features of the simulations and the model compare
well with available experimental data and provide a first quantitative measure
of the role of attractions in freely cooling granular streams.

text: Given only the URL of a Web page, can we identify its topic? We study this
problem in detail by exploring a large number of different feature sets and algorithms
on several datasets. We also show that the inherent overlap between topics and
the sparsity of the information in URLs makes this a very challenging problem.
Web page classification without a page’s content is desirable when the content
is not available at all, when a classification is needed before obtaining the
content, or when classification speed is of utmost importance. For our experiments
we used five different corpora comprising a total of about 3 million (URL, classification)
pairs. We evaluated several techniques for feature generation and classification
algorithms. The individual binary classifiers were then combined via boosting
into metabinary classifiers. We achieve typical F-measure values between 80 and
85, and a typical precision of around 86. The precision can be pushed further
over 90 while maintaining a typical level of recall between 30 and 40.

text: "We study a novel load balancing problem that arises in web search engines.
The problem is a combination of an offline assignment problem, where files need
to be (copied and) assigned to machines, and an online load balancing problem,
where requests ask for specific files and need to be assigned to a corresponding
machine, whose load is increased\r\nby this. We present simple deterministic algorithms
for this problem and exhibit an interesting trade-off between the available space
to make file copies and the obtainable makespan. We also give non-trivial lower
bounds for a large class of deterministic algorithms and present a randomized
algorithm that beats these bounds with high probability."

text: "The design of truthful auctions that approximate the optimal expected revenue
is a central problem in algorithmic mechanism design. 30 years after Myerson’s
characterization of Bayesian optimal auctions in single-parameter domains [8],
characterizing but also providing efficient mechanisms for multi-parameter domains
still remains a very important unsolved problem. Our work improves upon recent
results in this area, introducing new techniques for tackling the problem, while
also combining and extending recently introduced tools.\r\n\r\nIn particular we
give the first approximation algorithms for Bayesian auctions with multiple heterogeneous
items when bidders have additive valuations, budget constraints and general matroid
feasibility constraints."

text: Chandelier (axoaxonic) cells (ChCs) are a distinct group of GABAergic interneurons
that innervate the axon initial segments of pyramidal cells. However, their circuit
role and the function of their clearly defined anatomical specificity remain unclear.
Recent work has demonstrated that chandelier cells can produce depolarizing GABAergic
PSPs, occasionally driving postsynaptic targets to spike. On the other hand, other
work suggests that ChCs are hyperpolarizing and may have an inhibitory role. These
disparate functional effects may reflect heterogeneity among ChCs. Here, using
brain slices from transgenic mouse strains, we first demonstrate that, across
different neocortical areas and genetic backgrounds, upper Layer 2/3 ChCs belong
to a single electrophysiologically and morphologically defined population, extensively
sampling Layer 1 inputs with asymmetric dendrites. Consistent with being a single
cell type, we find electrical coupling between ChCs. We then investigate the effect
of chandelier cell activation on pyramidal neuron spiking in several conditions,
ranging from the resting membrane potential to stimuli designed to approximate
in vivo membrane potential dynamics. We find that under quiescent conditions,
chandelier cells are capable of both promoting and inhibiting spike generation,
depending on the postsynaptic membrane potential. However, during in vivo-like
membrane potential fluctuations, the dominant postsynaptic effect was a strong
inhibition. Thus, neocortical chandelier cells, even from within a homogeneous
population, appear to play a dual role in the circuit, helping to activate quiescent
pyramidal neurons, while at the same time inhibiting active ones.

text: Cortical neurons receive balanced excitatory and inhibitory synaptic currents.
Such a balance could be established and maintained in an experience-dependent
manner by synaptic plasticity at inhibitory synapses. We show that this mechanism
provides an explanation for the sparse firing patterns observed in response to
natural stimuli and fits well with a recently observed interaction of excitatory
and inhibitory receptive field plasticity. The introduction of inhibitory plasticity
in suitable recurrent networks provides a homeostatic mechanism that leads to
asynchronous irregular network states. Further, it can accommodate synaptic memories
with activity patterns that become indiscernible from the background state but
can be reactivated by external stimuli. Our results suggest an essential role
of inhibitory plasticity in the formation and maintenance of functional cortical
circuitry.

text: The accurate experimental determination of dipolar-coupling constants for
one-bond heteronuclear dipolar couplings in solids is a key for the quantification
of the amplitudes of motional processes. Averaging of the dipolar coupling reports
on motions on time scales up to the inverse of the coupling constant, in our case
tens of microseconds. Combining dipolar-coupling derived order parameters that
characterize the amplitudes of the motion with relaxation data leads to a more
precise characterization of the dynamical parameters and helps to disentangle
the amplitudes and the time scales of the motional processes, which impact relaxation
rates in a highly correlated way. Here. we describe and characterize an improved
experimental protocol – based on REDOR – to measure these couplings in perdeuterated
proteins with a reduced sensitivity to experimental missettings. Because such
effects are presently the dominant source of systematic errors in experimental
dipolar-coupling measurements, these compensated experiments should help to significantly
improve the precision of such data. A detailed comparison with other commonly
used pulse sequences (T-MREV, phase-inverted CP,R18 5/2, and R18 7/1) is provided.
