Snakes exhibit genetic sex determination, with female heterogametic sex chromosomes (ZZ males, ZW females). Extensive cytogenetic work has suggested that the level of sex chromosome heteromorphism varies among species, with Boidae having entirely homomorphic sex chromosomes, Viperidae having completely heteromorphic sex chromosomes, and Colubridae showing partial differentiation. Here, we take a genomic approach to compare sex chromosome differentiation in these three snake families. We identify homomorphic sex chromosomes in boas (Boidae), but completely heteromorphic sex chromosomes in both garter snakes (Colubridae) and pygmy rattlesnake (Viperidae). Detection of W-linked gametologs enables us to establish the presence of evolutionary strata on garter and pygmy rattlesnake sex chromosomes where recombination was abolished at different time points. Sequence analysis shows that all strata are shared between pygmy rattlesnake and garter snake, i.e., recombination was abolished between the sex chromosomes before the two lineages diverged. The sex-biased transmission of the Z and its hemizygosity in females can impact patterns of molecular evolution, and we show that rates of evolution for Z-linked genes are increased relative to their pseudoautosomal homologs, both at synonymous and amino acid sites (even after controlling for mutational biases). This demonstrates that mutation rates are male-biased in snakes (male-driven evolution), but also supports faster-Z evolution due to differential selective effects on the Z. Finally, we perform a transcriptome analysis in boa and pygmy rattlesnake to establish baseline levels of sex-biased expression in homomorphic sex chromosomes, and show that heteromorphic ZW chromosomes in rattlesnakes lack chromosome-wide dosage compensation. Our study provides the first full scale overview of the evolution of snake sex chromosomes at the genomic level, thus greatly expanding our knowledge of reptilian and vertebrate sex chromosomes evolution.

text: 'We present an interactive design system that allows non-expert users to create
animated mechanical characters. Given an articulated character as input, the user
iteratively creates an animation by sketching motion curves indicating how different
parts of the character should move. For each motion curve, our framework creates
an optimized mechanism that reproduces it as closely as possible. The resulting
mechanisms are attached to the character and then connected to each other using
gear trains, which are created in a semi-automated fashion. The mechanical assemblies
generated with our system can be driven with a single input driver, such as a
hand-operated crank or an electric motor, and they can be fabricated using rapid
prototyping devices. We demonstrate the versatility of our approach by designing
a wide range of mechanical characters, several of which we manufactured using
3D printing. While our pipeline is designed for characters driven by planar mechanisms,
significant parts of it extend directly to non-planar mechanisms, allowing us
to create characters with compelling 3D motions. '

text: 'We present a method for practical physical reproduction and design of homogeneous
materials with desired subsurface scattering. Our process uses a collection of
different pigments that can be suspended in a clear base material. Our goal is
to determine pigment concentrations that best reproduce the appearance and subsurface
scattering of a given target material. In order to achieve this task we first
fabricate a collection of material samples composed of known mixtures of the available
pigments with the base material. We then acquire their reflectance profiles using
a custom-built measurement device. We use the same device to measure the reflectance
profile of a target material. Based on the database of mappings from pigment concentrations
to reflectance profiles, we use an optimization process to compute the concentration
of pigments to best replicate the target material appearance. We demonstrate the
practicality of our method by reproducing a variety of different translucent materials.
We also present a tool that allows the user to explore the range of achievable
appearances for a given set of pigments. '

text: Animated animatronic figures are a unique way to give physical presence to
a character. However, their movement and expressions are often limited due to
mechanical constraints. In this paper, we propose a complete process for augmenting
physical avatars using projector-based illumination, significantly increasing
their expressiveness. Given an input animation, the system decomposes the motion
into low-frequency motion that can be physically reproduced by the animatronic
head and high-frequency details that are added using projected shading. At the
core is a spatio-temporal optimization process that compresses the motion in gradient
space, ensuring faithful motion replay while respecting the physical limitations
of the system. We also propose a complete multi-camera and projection system,
including a novel defocused projection and subsurface scattering compensation
scheme. The result of our system is a highly expressive physical avatar that features
facial details and motion otherwise unattainable due to physical constraints.

text: Most additive manufacturing technologies work by layering, i.e. slicing the
shape and then generating each slice independently. This introduces an anisotropy
into the process, often as different accuracies in the tangential and normal directions,
but also in terms of other parameters such as build speed or tensile strength
and strain. We model this as an anisotropic cubic element. Our approach then finds
a compromise between modeling each part of the shape individually in the best
possible direction and using one direction for the whole shape part. In particular,
we compute an orthogonal basis and consider only the three basis vectors as slice
normals (i.e. fabrication directions). Then we optimize a decomposition of the
shape along this basis so that each part can be consistently sliced along one
of the basis vectors. In simulation, we show that this approach is superior to
slicing the whole shape in one direction, only. It also has clear benefits if
the shape is larger than the build volume of the available equipment.

text: We present a method for fabrication-oriented design of actuated deformable
characters that allows a user to automatically create physical replicas of digitally
designed characters using rapid manufacturing technologies. Given a deformable
character and a set of target poses as input, our method computes a small set
of actuators along with their locations on the surface and optimizes the internal
material distribution such that the resulting character exhibits the desired deformation
behavior. We approach this problem with a dedicated algorithm that combines finite-element
analysis, sparse regularization, and constrained optimization. We validate our
pipeline on a set of two- and three-dimensional example characters and present
results in simulation and physically-fabricated prototypes.

text: Force-deformation measurements of cloth exhibit significant hysteresis, and
many researchers have identified internal friction as the source of this effect.
However, it has not been incorporated into computer animation models of cloth.
In this paper, we propose a model of internal friction based on an augmented reparameterization
of Dahl's model, and we show that this model provides a good match to several
important features of cloth hysteresis even with a minimal set of parameters.
We also propose novel parameter estimation procedures that are based on simple
and inexpensive setups and need only sparse data, as opposed to the complex hardware
and dense data acquisition of previous methods. Finally, we provide an algorithm
for the efficient simulation of internal friction, and we demonstrate it on simulation
examples that show disparate behavior with and without internal friction.

text: We prove new upper and lower bounds for Banach space-valued stochastic integrals
with respect to a compensated Poisson random measure. Our estimates apply to Banach
spaces with non-trivial martingale (co)type and extend various results in the
literature. We also develop a Malliavin framework to interpret Poisson stochastic
integrals as vector-valued Skorohod integrals, and prove a Clark-Ocone representation
formula.

text: A new method fabricates custom surface reflectance and spatially varying bidirectional
reflectance distribution functions (svBRDFs). Researchers optimize a microgeometry
for a range of normal distribution functions and simulate the resulting surface's
effective reflectance. Using the simulation's results, they reproduce an input
svBRDF's appearance by distributing the microgeometry on the printed material's
surface. This method lets people print svBRDFs on planar samples with current
3D printing technology, even with a limited set of printing materials. It extends
naturally to printing svBRDFs on arbitrary shapes.
