--- _id: '2076' abstract: - lang: eng text: | 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. acknowledgement: Funded by NIH grants (R01GM076007 and R01GM093182) and a Packard Fellowship to DB. author: - first_name: Beatriz full_name: Beatriz Vicoso id: 49E1C5C6-F248-11E8-B48F-1D18A9856A87 last_name: Vicoso orcid: 0000-0002-4579-8306 - first_name: Jr full_name: Emerson, Jr J. last_name: Emerson - first_name: Yulia full_name: Zektser, Yulia last_name: Zektser - first_name: Shivani full_name: Mahajan, Shivani last_name: Mahajan - first_name: Doris full_name: Bachtrog, Doris last_name: Bachtrog citation: ama: 'Vicoso B, Emerson J, Zektser Y, Mahajan S, Bachtrog D.

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.

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.

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. author: - first_name: Amit full_name: Bermano, Amit H last_name: Bermano - first_name: Philipp full_name: Bruschweiler, Philipp last_name: Bruschweiler - first_name: Anselm full_name: Grundhöfer, Anselm last_name: Grundhöfer - first_name: Daisuke full_name: Iwai, Daisuke last_name: Iwai - first_name: Bernd full_name: Bernd Bickel id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Markus full_name: Groß, Markus S last_name: Groß citation: ama: Bermano A, Bruschweiler P, Grundhöfer A, Iwai D, Bickel B, Groß M.

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. author: - first_name: Kristian full_name: Hildebrand, Kristian last_name: Hildebrand - first_name: Bernd full_name: Bernd Bickel id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Marc full_name: Alexa, Marc last_name: Alexa citation: ama: Hildebrand K, Bickel B, Alexa M.

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. acknowledgement: This work was supported in part by the European Research Council (ERC-2011-StG-280135 Animetrics) and the Spanish Ministry of Economy (TIN2012-35840). author: - first_name: Eder full_name: Miguel, Eder last_name: Miguel - first_name: Rasmus full_name: Tamstorf, Rasmus last_name: Tamstorf - first_name: Derek full_name: Bradley, Derek J last_name: Bradley - first_name: Sara full_name: Schvartzman, Sara C last_name: Schvartzman - first_name: Bernhard full_name: Thomaszewski, Bernhard last_name: Thomaszewski - first_name: Bernd full_name: Bernd Bickel id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Wojciech full_name: Matusik, Wojciech last_name: Matusik - first_name: Steve full_name: Marschner, Steve last_name: Marschner - first_name: Miguel full_name: Otaduy, Miguel A last_name: Otaduy citation: ama: Miguel E, Tamstorf R, Bradley D, et al.

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. author: - first_name: Olivier full_name: Rouiller, Olivier last_name: Rouiller - first_name: Bernd full_name: Bernd Bickel id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 - first_name: Jan full_name: Kautz, Jan last_name: Kautz - first_name: Wojciech full_name: Matusik, Wojciech last_name: Matusik - first_name: Marc full_name: Alexa, Marc last_name: Alexa citation: ama: Rouiller O, Bickel B, Kautz J, Matusik W, Alexa M. 3D printing spatially varying BRDFs.
