Bioactive Ion‐Confined Ultracapacitive Memristors with Neuromorphic Functions [PDF]
Angewandte Chemie, Volume 136, Issue 51, December 16, 2024.Pronounced physisorption of bioactive cations with a hydrophobic alkyl chain by porous carbons with a negative zeta potential results in confined cations, which triggers anion enrichment and depletion under electric polarization and enables rapid differential ionic memresistance behavior for cations with strong and weak interactions with porous carbons.

Determination of the temperature distribution in a minichannel using ANSYS CFX and a procedure based on the Trefftz functions [PDF]
EPJ Web of Conferences, 2017 This work discusses the mathematical model for laminar-flow heat transfer in a minichannel. The boundary conditions in the form of temperature distributions on the outer sides of the channel walls were determined from experimental data.

Temperature Identification in the Structural Elements of Non-Contacting Face Seals by Using Trefftz Functions [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2014 Phenomena of the heat transfer in non-contacting face seals was described by partial differential equation of the second order and boundary conditions. In this way, the mathematical model was developed for the sealing rings.

Journal of King Saud University - Science, 2018 AbstractThe paper develops a weak-form integral equation method (WFIEM) for solving the singularly perturbed convection–diffusion equation, which is too ill-posed to find the singular solution using conventional methods. We use Green’s second identity to generate integral equation, which includes a source term and boundary functions on the space-time ...

Nobody likes to sleep alone: aspiring to kinship futures in post‐Soviet Cuba
Journal of the Royal Anthropological Institute, Volume 29, Issue 4, Page 745-762, December 2023., 2023 Abstract In post‐Soviet Cuba, instead of the political future envisioned by Revolutionary authorities, poor residents of Havana aspire to create kinship futures where there is no need to ‘sleep alone’. Here, the idea of ‘sleeping together’ represents a trustworthy social bond that shelters a person from loneliness over time. For these habaneros, sexual
