text: Motion vision is essential for navigating through the environment. Due to
its genetic amenability, the fruit fly Drosophila has been serving for a lengthy
period as a model organism for studying optomotor behavior as elicited by large-field
horizontal motion. However, the neurons underlying the control of this behavior
have not been studied in Drosophila so far. Here we report the first whole cell
recordings from three cells of the horizontal system (HSN, HSE, and HSS) in the
lobula plate of Drosophila. All three HS cells are tuned to large-field horizontal
motion in a direction-selective way; they become excited by front-to-back motion
and inhibited by back-to-front motion in the ipsilateral field of view. The response
properties of HS cells such as contrast and velocity dependence are in accordance
with the correlation-type model of motion detection. Neurobiotin injection suggests
extensive coupling among ipsilateral HS cells and additional coupling to tangential
cells that have their dendrites in the contralateral hemisphere of the brain.
This connectivity scheme accounts for the complex layout of their receptive fields
and explains their sensitivity both to ipsilateral and to contralateral motion.
Thus the main response properties of Drosophila HS cells are strikingly similar
to the responses of their counterparts in the blowfly Calliphora, although we
found substantial differences with respect to their dendritic structure and connectivity.
This long-awaited functional characterization of HS cells in Drosophila provides
the basis for the future dissection of optomotor behavior and the underlying neural
circuitry by combining genetics, physiology, and behavior.

text: The X or Z chromosome has several characteristics that distinguish it from
the autosomes, namely hemizygosity in the heterogametic sex, and a potentially
different effective population size, both of which may influence the rate and
nature of evolution. In particular, there may be an accelerated rate of adaptive
change for X-linked compared to autosomal coding sequences, often referred to
as the Faster-X effect. Empirical studies have indicated that the strength of
Faster-X evolution varies among different species, and theoretical treatments
have shown that demography and mating system can substantially affect the degree
of Faster-X evolution. Here we integrate genomic data on Faster-X evolution from
a variety of animals with the demographic factors, mating system, and sex chromosome
regulatory characteristics that may influence it. Our results suggest that differences
in effective population size and mechanisms of dosage compensation may influence
the perceived extent of Faster-X evolution, and help to explain several clade-specific
patterns that we observe.

text: "This thesis investigates the combination of data-driven and physically based
techniques for acquiring, modeling, and animating deformable materials, with a
special focus on human faces. Furthermore, based on these techniques, we introduce
a data-driven process for designing and fabricating materials with desired deformation
behavior. \nRealistic simulation behavior, surface details, and appearance are
still demanding tasks. Neither pure data-driven, pure procedural, nor pure physical
methods are best suited for accurate synthesis of facial motion and details (both
for appearance and geometry), due to the difficulties in model design, parameter
estimation, and desired controllability for animators. Capturing of a small but
representative amount of real data, and then synthesizing diverse on-demand examples
with physically-based models and real data as input benefits from both sides:
Highly realistic model behavior due to real-world data and controllability due
to physically-based models.\nTo model the face and its behavior, hybrid physically-based
and data-driven approaches are elaborated. We investigate surface-based representations
as well as a solid representation based on FEM. To achieve realistic behavior,
we propose to build light-weighted data capture devices to acquire real-world
data to estimate model parameters and to employ concepts from data-driven modeling
techniques and machine learning. The resulting models support simple acquisition
systems, offer techniques to process and extract model parameters from real-world
data, provide a compact representation of the facial geometry and its motion,
and allow intuitive editing. We demonstrate applications such as capture of facial
geometry and motion and real-time animation and transfer of facial details, and
show that our soft tissue model can react to external forces and produce realistic
deformations beyond facial expressions.\nBased on this model, we furthermore introduce
a data-driven process for designing and fabricating materials with desired deformation
behavior. The process starts with measuring deformation properties of base materials.
Each material is represented as a non-linear stress-strain relationship in a finite-element
model. For material design and fabrication, we introduce an optimization process
that finds the best combination of base materials that meets a user’s criteria
specified by example deformations. Our algorithm employs a number of strategies
to prune poor solutions from the combinatorial search space. We finally demonstrate
the complete process by designing and fabricating objects with complex heterogeneous
materials using modern multi-material 3D printers.\n"

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: 'This chapter tackles a difficult challenge: presenting signal processing
material to non-experts. This chapter is meant to be comprehensible to people
who have some math background, including a course in linear algebra and basic
statistics, but do not specialize in mathematics, engineering, or related fields.
Some formulas assume the reader is familiar with matrices and basic matrix operations,
but not more advanced material. Furthermore, we tried to make the chapter readable
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
BCI data.'

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: Recent years have seen tremendous progress in the field of cold and ultracold
molecules. A central goal in the field is currently the realization of stable
rovibronic ground-state molecular samples in the regime of quantum degeneracy,
e.g. in the form of molecular Bose-Einstein condensates, molecular degenerate
Fermi gases, or, when an optical lattice is present, molecular Mott-insulator
phases. However, molecular samples are not readily cooled to the extremely low
temperatures at which quantum degeneracy occurs. In particular, laser cooling,
the \'workhorse\' for the field of atomic quantum gases, is generally not applicable
to molecular samples. Here we take an important step beyond previous work1 and
provide details on the realization of an ultracold quantum gas of ground-state
dimer molecules trapped in an optical lattice as recently reported in Ref. 2.
We demonstrate full control over all internal and external quantum degrees of
freedom for the ground-state molecules by deterministically preparing the molecules
in a single quantum state, i.e. in a specific hyperfine sublevel of the rovibronic
ground state, while the molecules are trapped in the motional ground state of
the individual lattice wells. We circumvent the problem of cooling by associating
weakly-bound molecules out of a zero-temperature atomic Mott-insulator state and
by transferring these to the absolute ground state in a four-photon STIRAP process.
Our preparation procedure directly leads to a long-lived, lattice-trapped molecular
many-body state, which we expect to form the platform for many of the envisioned
future experiments with molecular quantum gases, e.g. on precision molecular spectroscopy,
quantum information science, and dipolar quantum systems.

text: Control over all internal and external degrees of freedom of molecules at
the level of single quantum states will enable a series of fundamental studies
in physics and chemistry1,2. In particular, samples of ground-state molecules
at ultralow temperatures and high number densities will facilitate new quantum-gas
studies3 and future applications in quantum information science4. However, high
phase-space densities for molecular samples are not readily attainable because
efficient cooling techniques such as laser cooling are lacking. Here we produce
an ultracold and dense sample of molecules in a single hyperfine level of the
rovibronic ground state with each molecule individually trapped in the motional
ground state of an optical lattice well. Starting from a zero-temperature atomic
Mott-insulator state with optimized double-site occupancy6, weakly bound dimer
molecules are efficiently associated on a Feshbach resonance7 and subsequently
transferred to the rovibronic ground state by a stimulated four-photon process
with >50% efficiency. The molecules are trapped in the lattice and have a lifetime
of 8 s. Our results present a crucial step towards Bose-Einstein condensation
of ground-state molecules and, when suitably generalized to polar heteronuclear
molecules, the realization of dipolar quantum-gas phases in optical lattices8-10.

text: We report on the observation of confinement-induced resonances in strongly
interacting quantum-gas systems with tunable interactions for one- and two-dimensional
geometry. Atom-atom scattering is substantially modified when the s-wave scattering
length approaches the length scale associated with the tight transversal confinement,
leading to characteristic loss and heating signatures. Upon introducing an anisotropy
for the transversal confinement we observe a splitting of the confinement-induced
resonance. With increasing anisotropy additional resonances appear. In the limit
of a two-dimensional system we find that one resonance persists.

text: The phenomenon of matter-wave interference lies at the heart of quantum physics.
It has been observed in various contexts in the limit of non-interacting particles
as a single-particle effect. Here we observe and control matter-wave interference
whose evolution is driven by interparticle interactions. In a multi-path matter-wave
interferometer, the macroscopic manybody wave function of an interacting atomic
Bose-Einstein condensate develops a regular interference pattern, allowing us
to detect and directly visualize the effect of interaction-induced phase shifts.
We demonstrate control over the phase evolution by inhibiting interaction-induced
dephasing and by refocusing a dephased macroscopic matter wave in a spin-echo-type
experiment. Our results show that interactions in a many-body system lead to a
surprisingly coherent evolution, possibly enabling narrow-band and high-brightness
matterwave interferometers based on atom lasers.

text: Particles in a perfect lattice potential perform Bloch oscillations when subject
to a constant force, leading to localization and preventing conductivity. For
a weakly interacting Bose-Einstein condensate of Cs atoms, we observe giant center-of-mass
oscillations in position space with a displacement across hundreds of lattice
sites when we add a periodic modulation to the force near the Bloch frequency.
We study the dependence of these "super" Bloch oscillations on lattice
depth, modulation amplitude, and modulation frequency and show that they provide
a means to induce linear transport in a dissipation-free lattice.

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: This paper describes a passive stereo system for capturing the 3D geometry
of a face in a single-shot under standard light sources. The system is low-cost
and easy to deploy. Results are submillimeter accurate and commensurate with those
from state-ofthe-art systems based on active lighting, and the models meet the
quality requirements of a demanding domain like the movie industry. Recovered
models are shown for captures from both high-end cameras in a studio setting and
from a consumer binocular-stereo camera, demonstrating scalability across a spectrum
of camera deployments, and showing the potential for 3D face modeling to move
beyond the professional arena and into the emerging consumer market in stereoscopic
photography. Our primary technical contribution is a modification of standard
stereo refinement methods to capture pore-scale geometry, using a qualitative
approach that produces visually realistic results. The second technical contribution
is a calibration method suited to face capture systems. The systemic contribution
includes multiple demonstrations of system robustness and quality. These include
capture in a studio setup, capture off a consumer binocular-stereo camera, scanning
of faces of varying gender and ethnicity and age, capture of highly-transient
facial expression, and scanning a physical mask to provide ground-truth validation.

text: Point-based graphics has gained much attention as an alternative to polygon-based
approaches because of its simplicity and flexibility. However, current point-based
techniques do not provide a sufficient rendering quality for translucent materials
such as human skin. In this paper, we propose a point-based framework with subsurface
scattering of light, which is important to create the soft and semi-translucent
appearance of human skin. To accurately simulate subsurface scattering in multilayered
materials, we present splat-based diffusion to apply a linear combination of several
Gaussian basis functions to each splat in object space. Compared to existing point-based
approaches, our method offers a significantly improved visual quality in rendering
human faces and provides a similar visual quality to polygon-based rendering using
the texture space diffusion technique. We demonstrate the effectiveness of our
approach in rendering scanned faces realistically.

text: This paper introduces a data-driven process for designing and fabricating
materials with desired deformation behavior. Our process starts with measuring
deformation properties of base materials. For each base material we acquire a
set of example deformations, and we represent the material as a non-linear stress-strain
relationship in a finite-element model. We have validated our material measurement
process by comparing simulations of arbitrary stacks of base materials with measured
deformations of fabricated material stacks. After material measurement, our process
continues with designing stacked layers of base materials. We introduce an optimization
process that finds the best combination of stacked layers that meets a user's
criteria specified by example deformations. Our algorithm employs a number of
strategies to prune poor solutions from the combinatorial search space. We demonstrate
the complete process by designing and fabricating objects with complex heterogeneous
materials using modern multi-material 3D printers.

text: We develop a theory of Malliavin calculus for Banach space-valued random variables.
Using radonifying operators instead of symmetric tensor products we extend the
Wiener-Itô isometry to Banach spaces. In the white noise case we obtain two sided
Lp-estimates for multiple stochastic integrals in arbitrary Banach spaces. It
is shown that the Malliavin derivative is bounded on vector-valued Wiener-Itô
chaoses. Our main tools are decoupling inequalities for vector-valued random variables.
In the opposite direction we use Meyer's inequalities to give a new proof of a
decoupling result for Gaussian chaoses in UMD Banach spaces.

text: We develop an analytic model of vector correlations in rotationally inelastic
atom-diatom collisions and test it against the much examined Ar-NO (X2Π) system.
Based on the Fraunhofer scattering of matter waves, the model furnishes complex
scattering amplitudes needed to evaluate the polarization moments characterizing
the quantum stereodynamics. The analytic polarization moments are found to be
in an excellent agreement with experimental results and with close-coupling calculations
available at thermal energies. The model reveals that the stereodynamics is governed
by diffraction from the repulsive core of the Ar-NO potential, which can be characterized
by a single Legendre moment.

text: 'Following upon our recent work on vector correlations in the Ar-NO collisions
[Lemeshko and Friedrich, Phys. Chem. Chem. Phys. 12, 1038 (2010)], we compare
model results with close-coupling calculations for a range of channels and collision
energies for the He-NO system. The striking agreement between the model and exact
polarization moments indicates that the stereodynamics of rotationally inelastic
atom-molecule collisions at thermal energies is governed by diffraction of matter
waves from a two-dimensional repulsive core of the atom-molecule potential. Furthermore,
the model polarization moments characterizing the He-NO, He- O2, He-OH, and He-CaH
stereodynamics are found to coalesce into a single, distinctive pattern, which
can serve as a "fingerprint" to identify diffraction-driven stereodynamics
in future work. '

text: We evaluate the shifts imparted to vibrational and rotational levels of a
linear molecule by a nonresonant laser field at intensities of up to 10 12 W/cm2.
Both types of shift are found to be either positive or negative, depending on
the initial rotational state acted upon by the field. An adiabatic field-molecule
interaction imparts a rotational energy shift which is negative and exceeds the
concomitant positive vibrational shift by a few orders of magnitude. The rovibrational
states are thus pushed downward in such a field. A nonresonant pulsed laser field
that interacts nonadiabatically with the molecule is found to impart rotational
and vibrational shifts of the same order of magnitude. The nonadiabatic energy
transfer occurs most readily at a pulse duration which amounts to about a tenth
of the molecule's rotational period and vanishes when the sudden regime is attained
for shorter pulses. We applied our treatment to the much-studied 87Rb2 molecule
in the last bound vibrational levels of its lowest singlet and triplet electronic
states. Our calculations indicate that 15 and 1.5 ns laser pulses of an intensity
in excess of 5 × 109 W/cm2 are capable of dissociating the molecule due to the
vibrational shift. Lesser shifts can be used to fine-tune the rovibrational levels
and thereby affect collisional resonances by the nonresonant light. The energy
shifts due to laser intensities of 109 W/cm2 may be discernible spectroscopically,
with a 10 MHz resolution.
