text: 'Gossip, also known as epidemic dissemination, is becoming an increasingly
popular technique in distributed systems. Yet, it has remained a partially open
question: how robust are such protocols? We consider a natural extension of the
random phone-call model (introduced by Karp et al. [1]), and we analyze two different
notions of robustness: the ability to tolerate adaptive failures, and the ability
to tolerate oblivious failures. For adaptive failures, we present a new gossip
protocol, TrickleGossip, which achieves near-optimal O(n log 3 n) message complexity.
To the best of our knowledge, this is the first epidemic-style protocol that can
tolerate adaptive failures. We also show a direct relation between resilience
and message complexity, demonstrating that gossip protocols which tolerate a large
number of adaptive failures need to use a super-linear number of messages with
high probability. For oblivious failures, we present a new gossip protocol, CoordinatedGossip,
that achieves optimal O(n) message complexity. This protocol makes novel use of
the universe reduction technique to limit the message complexity.'

text: This paper studies non-cryptographic authenticated broadcast in radio networks
subject to malicious failures. We introduce two protocols that address this problem.
The first, NeighborWatchRB, makes use of a novel strategy in which honest devices
monitor their neighbors for malicious behavior. Second, we present a more robust
variant, MultiPathRB, that tolerates the maximum possible density of malicious
devices per region, using an elaborate voting strategy. We also introduce a new
proof technique to show that both protocols ensure asymptotically optimal running
time. We demonstrate the fault tolerance of our protocols through extensive simulation.
Simulations show the practical superiority of the NeighborWatchRB protocol (an
advantage hidden in the constants of the asymptotic complexity). The NeighborWatchRB
protocol even performs relatively well when compared to the simple, fast epidemic
protocols commonly used in the radio setting, protocols that tolerate no malicious
faults. We therefore believe that the overhead for ensuring authenticated broadcast
is reasonable, especially in applications that use authenticated broadcast only
when necessary, such as distributing an authenticated digest.

text: Set agreement [4] is a fundamental problem in distributed computing, in which
processes collectively choose a small subset of values from a larger set of proposals.
Set agreement has been extensively studied in both synchronous and asynchronous
systems [10,11,3,5,8,9]. Real world distributed systems, however, are neither
purely synchronous nor purely asynchronous. To describe such a system, Dwork et
al. [6] introduced the idea of partial synchrony. They assume for every execution
some (unknown) time GST (global stabilization time), after which the system is
synchronous. In a recent paper [1,2], we study the complexity of set agreement
in the context of partially synchronous systems, determining the minimum-sized
window of synchrony in which set agreement can be solved. We show that at least
⌊t/k⌋ + 2 synchronous rounds are required for k-set agreement, where t < n
is the number of crashes, and k is the agreement parameter of the set agreement
task. We then introduce an algorithm that terminates in any window of synchrony
of size at least ⌊t/k⌋ + 4 rounds. Together, these results tightly bound the inherent
price of tolerating some asynchrony.

Some formulas assume the reader is familiar with matrices and basic matrix operations,

even if you skip the formulas. Nevertheless, we include some simple methods to
demonstrate the basics of adaptive data processing, then we proceed with some
advanced methods that are fundamental in adaptive signal processing, and are likely
to be useful in a variety of applications. The advanced algorithms are also online
available [30]. In the second part, these techniques are applied to some real-world

text: Morphogens are secreted signalling molecules that act in a graded manner to
control the pattern of cellular differentiation in developing tissues. An example
is Sonic hedgehog (Shh), which acts in several developing vertebrate tissues,
including the central nervous system, to provide positional information during
embryonic patterning. Here we address how Shh signalling assigns the positional
identities of distinct neuronal subtype progenitors throughout the ventral neural
tube. Assays of intracellular signal transduction and gene expression indicate
that the duration as well as level of signalling is critical for morphogen interpretation.
Progenitors of the ventral neuronal subtypes are established sequentially, with
progressively more ventral identities requiring correspondingly higher levels
and longer periods of Shh signalling. Moreover, cells remain sensitive to changes
in Shh signalling for an extended time, reverting to antecedent identities if
signalling levels fall below a threshold. Thus, the duration of signalling is
important not only for the assignment but also for the refinement and maintenance
of positional identity. Together the data suggest a dynamic model for ventral
neural tube patterning in which positional information corresponds to the time
integral of Shh signalling. This suggests an alternative to conventional models
of morphogen action that rely solely on the level of signalling.

text: The epitaxial growth of germanium on silicon leads to the self-assembly of
SiGe nanocrystals by a process that allows the size, composition and position
of the nanocrystals to be controlled. This level of control, combined with an
inherent compatibility with silicon technology, could prove useful in nanoelectronic
applications. Here, we report the confinement of holes in quantum-dot devices
made by directly contacting individual SiGe nanocrystals with aluminium electrodes,
and the production of hybrid superconductor- semiconductor devices, such as resonant
supercurrent transistors, when the quantum dot is strongly coupled to the electrodes.
Charge transport measurements on weakly coupled quantum dots reveal discrete energy
spectra, with the confined hole states displaying anisotropic gyromagnetic factors
and strong spin-orbit coupling with pronounced dependences on gate voltage and
magnetic field.

text: We investigate electronic transport in n-i-n GaN nanowires with and without
AlN double barriers. The nanowires are grown by catalyst-free, plasma-assisted
molecular beam epitaxy enabling abrupt GaN/AlN interfaces as well as longitudinal
n-type doping modulation. At low temperature, transport in n-i-n GaN nanowires
is dominated by the Coulomb blockade effect. Carriers are confined in the undoped
middle region, forming single or multiple islands with a characteristic length
of ∼100 nm. The incorporation of two AlN tunnel barriers causes confinement to
occur within the GaN dot in between. In the case of a 6 nm thick dot and 2 nm
thick barriers, we observe characteristic signatures of Coulomb-blockaded transport
in single quantum dots with discrete energy states. For thinner dots and barriers,
Coulomb-blockade effects do not play a significant role while the onset of resonant
tunneling via the confined quantum levels is accompanied by a negative differential
resistance surviving up to ∼150 K.

text: We present the realization of a cavity quantum electrodynamics setup in which
photons of strongly different lifetimes are engineered in different harmonic modes
of the same cavity. We achieve this in a superconducting transmission line resonator
with superconducting qubits coupled to the different modes. One cavity mode is
strongly coupled to a detection line for qubit state readout, while a second long
lifetime mode is used for photon storage and coherent quantum operations. We demonstrate
sideband-based measurement of photon coherence, generation of n photon Fock states
and the scaling of the sideband Rabi frequency with √n using a scheme that may
be extended to realize sideband-based two-qubit logic gates.

text: The quantum properties of electromagnetic, mechanical or other harmonic oscillators
can be revealed by investigating their strong coherent coupling to a single quantum
two level system in an approach known as cavity quantum electrodynamics (QED).
At temperatures much lower than the characteristic energy level spacing the observation
of vacuum Rabi oscillations or mode splittings with one or a few quanta asserts
the quantum nature of the oscillator. Here, we study how the classical response
of a cavity QED system emerges from the quantum one when its thermal occupation-or
effective temperature-is raised gradually over 5 orders of magnitude. In this
way we explore in detail the continuous quantum-to-classical crossover and demonstrate
how to extract effective cavity field temperatures from both spectroscopic and
time-resolved vacuum Rabi measurements.

text: A number of superconducting qubits, such as the transmon or the phase qubit,
have an energy level structure with small anharmonicity. This allows for convenient
access of higher excited states with similar frequencies. However, special care
has to be taken to avoid unwanted higher-level populations when using short control
pulses. Here we demonstrate the preparation of arbitrary three level superposition
states using optimal control techniques in a transmon. Performing dispersive readout,
we extract the populations of all three levels of the qutrit and study the coherence
of its excited states. Finally we demonstrate full quantum state tomography of
the prepared qutrit states and evaluate the fidelities of a set of states, finding
on average 95%.

text: Retinitis pigmentosa refers to a diverse group of hereditary diseases that
lead to incurable blindness, affecting two million people worldwide. As a common
pathology, rod photoreceptors die early, whereas light-insensitive, morphologically
altered cone photoreceptors persist longer. It is unknown if these cones are accessible
for therapeutic intervention. Here, we show that expression of archaebacterial
halorhodopsin in light-insensitive cones can substitute for the native phototransduction
cascade and restore light sensitivity in mouse models of retinitis pigmentosa.
Resensitized photoreceptors activate all retinal cone pathways, drive sophisticated
retinal circuit functions (including directional selectivity), activate cortical
circuits, and mediate visually guided behaviors. Using human ex vivo retinas,
we show that halorhodopsin can reactivate light-insensitive human photoreceptors.
Finally, we identified blind patients with persisting, light-insensitive cones
for potential halorhodopsin-based therapy.

text: 'Complex I is the first enzyme of the respiratory chain and has a central
role in cellular energy production, coupling electron transfer between NADH and
quinone to proton translocation by an unknown mechanism. Dysfunction of complex
I has been implicated in many human neurodegenerative diseases. We have determined
the structure of its hydrophilic domain previously. Here, we report the α-helical
structure of the membrane domain of complex I from Escherichia coli at 3.9 Å resolution.
The antiporter-like subunits NuoL/M/N each contain 14 conserved transmembrane
(TM) helices. Two of them are discontinuous, as in some transporters. Unexpectedly,
subunit NuoL also contains a 110-Å long amphipathic α-helix, spanning almost the
entire length of the domain. Furthermore, we have determined the structure of
the entire complex I from Thermus thermophilus at 4.5 Å resolution. The L-shaped
assembly consists of the α-helical model for the membrane domain, with 63 TM helices,
and the known structure of the hydrophilic domain. The architecture of the complex
provides strong clues about the coupling mechanism: the conformational changes
at the interface of the two main domains may drive the long amphipathic α-helix
of NuoL in a piston-like motion, tilting nearby discontinuous TM helices, resulting
in proton translocation.'

text: The immobilization of molecular switches onto inorganic supports has recently
become a hot topic as it can give rise to novel hybrid materials in which the
properties of the two components are mutually enhanced. Even more attractive is
the concept of “transferring” the switchable characteristics of single layers
of organic molecules onto the underlying inorganic components, rendering them
responsive to external stimuli as well. Of the various molecular switches studied,
azobenzene (AB) has arguably attracted most attention due to its simple molecular
structure, and because its “trigger” (light) is a noninvasive one, it can be delivered
instantaneously, and into a precise location. In order to fully realize its potential,
however, it is necessary to immobilize AB onto solid supports. It is the goal
of this manuscript to comprehensively yet concisely review such hybrid systems
which comprise AB forming well-defined self-assembled monolayers (SAMs) on planar
and curved (colloidal and nanoporous) inorganic surfaces. I discuss methods to
immobilize AB derivatives onto surfaces, strategies to ensure efficient AB isomerization,
ways to monitor the switching process, properties of these switchable hybrid materials,
and, last but not least, their emerging applications.

text: A range (Au, Pt, Pd) of metal nanoparticles (MNPs) has been prepared and functionalized
with (a) redox-active stalks containing tetrathiafulvalene (TTF) units, (b) [2]pseudorotaxanes
formed between these stalks and cyclobis(paraquat-p-phenylene) (CBPQT4+) rings,
and (c) bistable [2]rotaxane molecules where the dumbbell component contains a
1,5-dioxynaphthalene (DNP) unit, as well as a TTF unit, encircled by a CBPQT4+
ring. It transpires that the molecules present in (a) and (c) and the supermolecules
described in (b) retain their switching characteristics, previously observed in
solution, when they are immobilized onto MNPs. Moreover, their oxidation potentials
depend on the fraction, χ, of the molecules or supermolecules on the surface of
the nanoparticles. A variation in χ affects the oxidation potentials of the TTF
units to the extent that switching can be subjected to fine tuning as a result.
Specifically, increasing χ results in positive shifts (i) in the oxidation potentials
of the TTF unit in (a)−(c) and (ii) the reduction potentials of the CBPQT4+ rings
in (c). These shifts can be attributed to an increase in the electrostatic potential
surrounding the MNPs. Both the magnitude and the direction of these shifts are
reproduced by a model, based on the Poisson−Boltzmann equation coupled with charge-regulating
boundary conditions. Furthermore, the kinetics of relaxation from the metastable
state coconformation (MSCC) to the ground-state coconformation (GSCC) of the bistable
[2]rotaxane molecules also depends on χ, as well as on the nanoparticle diameter.
Increasing either of these parameters accelerates the rate of relaxation from
the MSCC to the GSCC. This rate is a function of (i) the activation energy for
the relaxation process associated with the bistable [2]rotaxane molecules in solution
and (ii) the electrostatic potential surrounding the MNPs. The electrostatic potential
depends on (i) the diameter of the MNPs, (ii) the amount of the bistable [2]rotaxane
molecules on the surface of the MNPs, and (iii) the equilibrium distribution of
the CBPQT4+ rings between the DNP and TTF recognition sites in the GSCC. This
electrostatic potential has also been quantified using the Poisson−Boltzmann equation,
leading to faithful estimates of the rate constants.

text: Photoresponsive gold nanoparticles dispersed in a solid/frozen matrix provide
a basis for sensors that “remember” whether the sample has ever exceeded the melting
temperature of the matrix. The operation of these sensors rests on the ability
to photoinduce metastable electric dipoles on NP surfaces – upon melting, these
dipoles drive NP aggregation, precipitation, and crosslinking. These events are
manifested by a pronounced color change.

text: Nanoparticles (NPs) and molecular/supramolecular switches have attracted considerable
interest during the past decade on account of their unique properties and prominent
roles in the fields of organic chemistry and materials science. Materials derived
from the combination of these two components are now emerging in the literature.
This critical review evaluates materials which comprise NPs functionalised with
well-defined self-assembled monolayers of molecular and supramolecular switches.
We draw attention to the fact that immobilisation of switches on NPs does not,
in general, hamper their switching ability, although it can impart new properties
on the supporting particles. This premise leads us to the discussion of systems
in which switching on the surfaces of NPs can be used to modulate reversibly a
range of NP properties—optical, fluorescent, electrical, magnetic—as well as the
controlled release of small molecules. Finally, we discuss examples in which molecular
switches direct reversible self-assembly of NPs (308 references).

text: We prove a generating function formula for the Betti numbers of Nakajima quiver
varieties. We prove that it is a q-deformation of the Weyl-Kac character formula.
In particular this implies that the constant term of the polynomial counting the
number of absolutely indecomposable representations of a quiver equals the multiplicity
of a certain weight in the corresponding Kac-Moody algebra, which was conjectured
by Kac in 1982.

text: In Hausel et al. (2008) [10] we presented a conjecture generalizing the Cauchy
formula for Macdonald polynomial. This conjecture encodes the mixed Hodge polynomials
of the character varieties of representations of the fundamental group of a punctured
Riemann surface of genus g. We proved several results which support this conjecture.
Here we announce new results which are consequences of those in Hausel et al.
(2008) [10].
