The scheduling of sparse matrix-vector multiplication on a massively parallel dap computer [PDF]

open access: yes, 1991
An efficient data structure is presented which supports general unstructured sparse matrix-vector multiplications on a Distributed Array of Processors (DAP). This approach seeks to reduce the inter-processor data movements and organises the operations in

Depletion of microglial compensation in glial network: Disease‐associated response dynamics in the revised amyloid hypothesis

open access: yesNeuroprotection, EarlyView.
The critical transition from amyloid pathology to irreversible neuronal loss in Alzheimer's disease hinges on the microglial response. This review aims to systematize the patterns of how microglia react within the glial context. Abstract Microglia mount coordinated, stage‐dependent compensatory programs in response to early amyloid β (Aβ) accumulation ...

Branched‐Chain Amino and Keto Acids Reduce Hepatocyte Lipid Droplet Size and Number via Distinct Proteomic Pathways

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Branched‐chain amino acids (BCAA) and their corresponding keto acids (BCKA) have been associated with changes in hepatic lipid metabolism and the resulting alterations in intracellular triglyceride concentrations. In this study, we utilized a previously established hepatocyte model to investigate the impact of BCAA and BCKA supplementation on ...

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

Adapting the interior point method for the solution of LPs on serial, coarse grain parallel and massively parallel computers [PDF]

open access: yes, 1990
In this paper we describe a unified scheme for implementing an interior point algorithm (IPM) over a range of computer architectures. In the inner iteration of the IPM a search direction is computed using Newton's method.

Climate requirements for cultivated Liberica coffee (Coffea liberica) and consequences for its use and development as a crop species

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
The global coffee industry, supporting 25 million smallholder farmers, is vulnerable to climate change. Diversifying the coffee species portfolio beyond Arabica and robusta is a promising intervention. Liberica coffee could provide adaptive capacity, although its climate parameters for cultivation are poorly known.
