Taking advantage of hybrid systems for sparse direct solvers via task-based runtimes [PDF]

, 2014
The ongoing hardware evolution exhibits an escalation in the number, as well as in the heterogeneity, of computing resources. The pressure to maintain reasonable levels of performance and portability forces application developers to leave the traditional

Desulfovibrio‐Hydrogen Sulfide Mediates Capsaicin‐Induced Oxidative Stress and Gut Inflammation via TXNIP/NLRP3 Pathway

Food Bioengineering, EarlyView.
ABSTRACT The intake of capsaicin can disrupt the gut microecology and impact health, yet its underlying mechanism is not fully elucidated. This study, by establishing capsaicin‐induced human microbiota‐associated (HMA) mouse models revealed the molecular mechanism by which capsaicin perturbs the gut microbiota and metabolites, leading to intestinal ...

Revisiting the minimum ignition energy of hydrogen–oxygen mixtures: Insights from experiment and theory

Case Studies in Thermal Engineering
The minimum ignition energy (MIE) of hydrogen–oxygen mixtures, reported as approximately 1.2 μJ, is over an order of magnitude lower than that of hydrogen–air mixtures, indicating heightened ignition hazards.

Contribution of Free Fatty Acids to Emulsion Building and Stability: Understanding the Mechanism From the Case Study of a Crude Red Palm Oil (Elaeis guineensis)—Based Emulsion Consumed in Africa and Known as Achu Soup/Sauce Jaune/Ncha

Food Chemistry International, EarlyView.
In an aqueous alkaline medium, fatty acids (from the hydrolysis of triglycerides or freely present in the oil) are ionised in order to form emulsifiers (carboxylates) which will physically stabilise the prepared emulsion. The higher the free fatty acids content of the oil and alkalinity of the solution, the higher will be the stability of the prepared ...

Experimental and Numerical Study on the Plasma-Laser-Induced Ignition of Strut Stabilizer at Different Locations

Aerospace
The minimum ignition equivalence ratio of the strut stabilizer is an important parameter in the design of integrated afterburners. The ignition location significantly affects the ignition equivalence ratio and flame propagation, and therefore, it should ...

Influence of plasma-assisted ignition on flame propagation and performance in a spark-ignition engine

Applications in Energy and Combustion Science, 2021
Lean-burn is an attractive concept for reasons of high thermal efficiency and low nitrogen oxide (NOx) emissions, however, successful implementation in spark-ignition (SI) engines turned out to be challenging because of misfire or partial burn caused by ...

Impact of tomato variety and homogenization pressure on in vitro lipid digestion and lycopene bioaccessibility in tomato emulsions

Food Biomacromolecules, EarlyView.
Tomato variety and processing impact lycopene bioaccessibility. Tomato emulsions with high pectin content decreased the in vitro lipid digestion and negatively affected lycopene bioaccessibility. High pressure homogenization may enhance the release of lycopene into emulsion oil droplets, but it may also reduce the transfer of lycopene into the micellar

Toxicological Evaluation of the Undesirable Components in Processed Infant Foods Using Artificial Intelligence

Future Postharvest and Food, EarlyView.
The detection of toxins in baby food using artificial intelligence. ABSTRACT Infant foods and baby formulas are becoming increasingly popular across the globe owing to their ease of consumption and nutritional value specific to infants. Impurities may find their way into the food chain at any point from the acquisition of raw materials to final ...
