The study presents a variational approach to the lattice Boltzmann method (LBM) for Couette flow, demonstrating that the bulk velocity and shear stress are linear in Mach number under Maxwell-type boundary conditions. This approach offers superior computational efficiency compared to the moment method, with the number of partial differential equations growing linearly with quadrature order. The method provides exact analytical solutions for the LBM bulk velocity field and shear stress, potentially benefiting novel lattice Boltzmann quadrature schemes and other flow calculations.

The article presents a histology-guided mathematical model to analyze tumor oxygenation, focusing on the sensitivity of various physical and computational parameters. The study involves a detailed examination of how different factors influence tumor oxygen levels, providing insights that could be crucial for cancer research and treatment strategies.

The government of Sierra Leone has reported the arrest of 13 military officials and one civilian following attacks in the nation's capital. These events occurred on a Sunday and resulted in 20 fatalities. Additionally, the attacks led to the escape of over 2,000 prisoners. The identities of those arrested have not been disclosed by the authorities. The situation is being described as an 'attempted coup', indicating a significant breach of national security and stability in the country.

Sierra Leone has arrested 13 military officials and one civilian following a failed coup attempt that resulted in 20 deaths and the release of over 2,000 prisoners. The incident has heightened tensions in Freetown, where security measures have been increased. President Julius Maada Bio, re-elected in June, faces a politically charged atmosphere with his main opponent rejecting the election results. The situation in Sierra Leone adds to regional instability, with recent successful coups in neighboring Guinea and Niger despite ECOWAS's non-coup policy.

Sierra Leone has arrested 13 military officials and one civilian following a failed coup attempt that resulted in 20 deaths and the release of over 2,000 prisoners. The incident has heightened tensions in Freetown, where security has been increased. President Julius Maada Bio, re-elected in June, faces a politically charged atmosphere with disputed election results. The situation in Sierra Leone adds to regional instability, with recent successful coups in neighboring Guinea and Niger despite ECOWAS's non-coup policy.

Authorities in Sierra Leone have arrested most of the leaders involved in an attempted break-in at key military sites, including the Wilberforce military barracks and the armory in Freetown. President Julius Maada Bio announced the arrests following a nationwide curfew imposed in response to the attacks. Security operations and investigations are ongoing, with calm reportedly restored in the capital.

Kel Mitchell provided a health update after being hospitalized with a bulging disc, reassuring fans of his recovery and expressing gratitude for their support. He detailed his symptoms and the medical care he received, emphasizing that the situation was less severe than initially feared. Mitchell is now recovering at home and continues to promote his upcoming projects, including the release of 'Good Burger 2' on Paramount+ and his appearance on the VH1 game show 'Celebrity Squares'.

The study characterizes the notch sensitivity of additively manufactured Inconel 718 produced by laser powder bed fusion. It evaluates the tensile strength of V-notched and smooth specimens in different orientations, using both total axial strain and localized notch diametral strain measurements, complemented by finite element analysis. Results indicate that notched specimens have higher tensile strength than smooth specimens, suggesting notch strengthening due to increased triaxial stress. Fractography analysis reveals a dominant ductile failure mode, with ductility decreasing with smaller notch root radii. The study concludes that L-PBF Inconel 718 material exhibits notch strengthening and isotropic tensile material performance, with further research needed on complex loading behaviors.

President Julius Maada Bio was re-elected in Sierra Leone, narrowly avoiding a runoff by securing 56 percent of the vote. His main opponent, Samura Kamara, who received 41 percent, rejected the results as not credible. Bio was sworn in an hour after the results were announced, amidst celebrations by his supporters. The election was a repeat of the 2018 contest, and comes at a time when Sierra Leone faces severe economic challenges, including high inflation, unemployment, and food insecurity.

Senior officials from Sierra Leone’s main opposition party accused the military of using live ammunition and tear gas at their headquarters in Freetown, raising tensions after presidential elections. The opposition candidate, Samura Kamara, and his supporters were reviewing election data when the military intervened. The police claimed they acted to disperse a crowd that was harassing people, but reports of live ammunition could not be confirmed. The incident highlights the volatile political climate in Sierra Leone following the elections.
