Simulating indirect lighting effects has been a challenging topic in many real-time rendering and design applications. This paper presents a novel method, based on precomputed radiance transfer, for rendering physically based, multi-bounce indirect lighting in real-time. Our key idea is to represent both the direct lighting and precomputed diffuse indirect transfer using a spectral mesh basis s...

Abstract Background: Depression in multiple sclerosis (MS) is poorly responsive to conventional pharmacotherapy, highlighting the need for clinical TMS trials. However, it unclear if MS depression suitable circuit-targeted therapeutics. We developed a technique identifying single treatment targets based on distributed brain circuit maps derived from symptom-causing lesions. then tested this usi...

Interactive rendering of global illumination effects is a challenging problem. While precomputed radiance transfer (PRT) is able to render such effects in real time the geometry is generally assumed static. This work proposes to replace the precomputed lighting response used in PRT by precomputed depth. Precomputing depth has the same cost as precomputing visibility, but allows visibility tests...

In-memory computing using emerging technologies such as Resistive Random-Access Memory (ReRAM) has been proposed a promising substitute for future applications to address the ‘von Neumann bottleneck’. Multiplication is key component inner product computation in every digital signal processing (DSP) application and complexity of multipliers increases greatly with bit-width. Distributed arithmeti...

Single-trace side-channel attacks are a serious threat to elliptic curve cryptography in practice because they can break also cryptosystems where scalars are nonces (e.g., ECDSA). Previously it was believed that single-trace attacks can be avoided by using scalar multiplication algorithms with regular patterns of operations but recently we have learned that they can be broken with correlation t...

View-based query answering is the problem of answering a query based only on the precomputed answers to a set of views. While this problem has been widely investigated in databases, it is largely unexplored in the context of Description Logic ontologies. Differently from traditional databases, Description Logics may express several forms of incomplete information, and this poses challenging pro...

We propose a simple fast spectral method for the Boltzmann collision operator with general collision kernels. Compared with the direct spectral method [8] which requires O(N6) memory to store precomputed weights and has O(N6) numerical complexity, the new method has complexity O(MN4 logN), where N is the number of discretization points in each velocity dimension, M is the total number discretiz...

In many fields of application, shortest path finding problems in very large graphs arise. Scenarios where large numbers of on-line queries for shortest paths have to be processed in real-time appear for example in traffic information systems. In such systems, the techniques considered to speed up the shortest path computation are usually based on precomputed information. One approach proposed o...

We are awash in proteins discovered through high-throughput sequencing projects. As only a minuscule fraction of these have been experimentally characterized, computational methods are widely used for automated annotation. Here, we introduce a user-friendly web interface for accurate protein function prediction using the SIFTER algorithm. SIFTER is a state-of-the-art sequence-based gene molecul...
