We describe a novel volumetric global illumination framework based on the Face-Centered Cubic (FCC) lattice. An FCC lattice has important advantages over a Cartesian lattice. It has higher packing density in the frequency domain, which translates to better sampling efficiency. Furthermore, it has the maximal possible kissing number (equivalent to the number of nearest neighbors of each site), which provides optimal 3D angular discretization among all lattices. We employ a new two-pass (illumination and rendering) global illumination scheme on an FCC lattice. This scheme exploits the angular discretization to greatly simplify the computation in multiple scattering and to minimize illumination information storage. The GPU has been utilized to further accelerate the rendering stage. We demonstrate our new framework with participating media and volume rendering with multiple scattering, where both are significantly faster than traditional techniques with comparable quality.

Background: Valvular heart disease (VHD), including both non-rheumatic valvular heart disease (NRVHD) and rheumatic valvular heart disease (RVHD), is a major global health concern. Moreover, the progression of VHD to heart failure (HF) poses substantial clinical and public health challenges. In light of the global population aging, alongside increasing cardiovascular risk factors, and the additional strain imposed by the COVID-19 pandemic, a timely reassessment of the VHD-related HF burden is urgently needed.

Global salinization increasingly threatens ecosystem integrity and the regulation of biogeochemical cycles. Our study reveals novel insights into the microbial contributions to the organohalide decomposition in saline environments, demonstrating the unprecedented ability of organohalide-respiring bacteria and to completely dechlorinate trichloroethene to non-toxic ethene under hypersaline conditions (up to 31.3 g/L) in long-term operations.

Background: Deformable medical image registration is a critical task in medical imaging-assisted diagnosis and treatment. In recent years, medical image registration methods based on deep learning have made significant success by leveraging prior knowledge, and the registration accuracy and computational efficiency have been greatly improved. Models based on Transformers have achieved better performance than convolutional neural network methods (ConvNet) in image registration.

Introduction: Hypertension is a major contributor to disability-adjusted life years (DALYs) worldwide, as highlighted by the Global Burden of Disease study (GBD 2021). Effective management of hypertension through medication can significantly lower the risks associated with the condition. It is important to recognize that not adhering to antihypertensive therapy often leads to negative health outcomes.
