Importance Sampling of the Micrograin Visible NDF

Computer Graphics Forum, Volume 44, Issue 4, July 2025.
Abstract Importance sampling of visible normal distribution functions (vNDF) is a required ingredient for the efficient rendering of microfacet‐based materials. In this paper, we explain how to sample the vNDF for the micrograin material model [LRPB23], which has been recently improved to handle height‐normal correlations through a new Geometric ...

Offloading traffic hotspots using moving small cells

, 2016
In this paper, the concept of moving small cells in mobile networks is presented and evaluated taking into account the dynamics of the system. We consider a small cell moving according to a Manhattan mobility model which is the case when the small cell ...

Prediction of the most fire‐sensitive point in building structures with differentiable agents for thermal simulators

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 18, Page 2584-2611, 18 July 2025.
Abstract Fire safety is crucial for ensuring the stability of building structures, yet evaluating whether a structure meets fire safety requirements is challenging. Fires can originate at any point within a structure, and simulating every potential fire scenario is both expensive and time‐consuming.

Analysis of Alternative Metrics for the PAPR Problem in OFDM Transmission

, 2011
The effective PAPR of the transmit signal is the standard metric to capture the effect of nonlinear distortion in OFDM transmission. A common rule of thumb is the log$(N)$ barrier where $N$ is the number of subcarriers which has been theoretically ...

Variations in Event‐Bed Thickness‐Frequency Distributions Near Volcanic Islands: Indicators of Varied Geological Processes

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract A variety of subaerial and submarine events, including mass‐wasting and volcanism, can generate sediment gravity flows and fallout deposits that are preserved in deep‐water stratigraphic records. This study examines whether event beds with differing depositional and transport histories exhibit distinct thickness‐frequency distributions ...

Threshold Saturation for Nonbinary SC-LDPC Codes on the Binary Erasure Channel

, 2016
We analyze the asymptotic performance of nonbinary spatially-coupled low-density parity-check (SC-LDPC) code ensembles defined over the general linear group on the binary erasure channel. In particular, we prove threshold saturation of belief propagation

MEA‐seqX: High‐Resolution Profiling of Large‐Scale Electrophysiological and Transcriptional Network Dynamics

Advanced Science, Volume 12, Issue 20, May 29, 2025.
How can we fully understand brain function and disease without uncovering the causal coordination between molecular and neural activity across space and time? MEA‐seqX tackles this challenge by integrating advanced electrophysiology, spatial transcriptomics, and artificial intelligence predictions, revealing multiscale dynamics.
