Therefore, here we will describe the implementation of the hair scattering model described in the paper A Practical and Controllable Hair and Fur Model for Production Path Tracing , by Matt Jen-Yuan Chiang, Benedikt Bitterli, Chuck Tappan, and Brent Burley. The paper itself is available here: benedikt-bitterli.me/ pchfm/. See the “Further Reading” section at the end of this document for more in...

Measured material representations like Bidirectional Texture Functions or Reflectance Fields offer very realistic appearance but the user is currently not capable of changing this appearance in an effective and intuitive way. Such editing operations would require a low-dimensional but expressive model for appearance that exposes only a small set of intuitively editable parameters (1D-sliders, 2...

In this short note, we extend the notion of texture symmetry to the skewed symmetry and propose a method for calculating the skewed symmetry of a non-rectangular or affine-distorted bidirectional texture. Results for a number of natural textures are shown.

Certified programming is one of the desirable approaches to developing dependable software, where expected properties of programs are formally proved by proof assistants such as Coq. One way for certified programming with Coq is to define a function, give proofs for its properties in Coq, and then extract a program in OCaml. Another way for certified programming with Coq is to import the defini...

Convolutional and bidirectional recurrent neural networks have achieved considerable performance gains as acoustic models in automatic speech recognition in recent years. Latest architectures unify long short-term memory, gated recurrent unit and convolutional neural networks by stacking these different neural network types on each other, and providing short and long-term features to different ...

It is well-known that any admissible unidirectional heuristic search algorithm must expand all states whose f -value is smaller than the optimal solution cost when using a consistent heuristic. Such states are called “surely expanded” (s.e.). A recent study characterized s.e. pairs of states for bidirectional search with consistent heuristics: if a pair of states is s.e. then at least one of th...

Multiple cellular components are involved in the complex pathological process following central nervous system (CNS) injury, including neurons, glial cells and endothelial cells. Previous studies and neurotherapeutic clinical trials have assessed the molecular mechanisms that underlie neuronal cell death following CNS injury. However, this approach has largely failed to reduce CNS damage or imp...

Severely stenosed radiation-induced benign strictures around the level of cricopharyngeus post-radical chemoradiation for head and neck or upper esophageal cancers pose significant management problems. We report our technique of bidirectional assessment and dilatation of pharyngoesophageal strictures in patients with an in situ percutaneous endoscopic gastrostomy (PEG) tube. The upper gastroint...

One of the most prevalent forms of violence in contemporary society is the victimization of intimate partners. Although it has been established that homeless young people experience high levels of victimization on the street, little is known about partner violence (PV) experiences among this group, especially bidirectional violence. As such, the purpose of this study is to examine the prevalenc...

Lenses are one of the most popular approaches to define bidirectional transformations between data models. However, writing a lens transformation typically implies describing the concrete steps that convert values in a source schema to values in a target schema. In contrast, many XML-based languages allow writing structure-shy programs that manipulate only specific parts of XML documents withou...
