Some results on the dynamics generated by the Bazykin model
Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2006 A predator-prey model formerly proposed by A. Bazykin et al. [Bifurcation diagrams of planar dynamical systems (1985)] is analyzed in the case when two of the four parameters are kept fixed.

Advanced Science, EarlyView.The external field exceeds Hd, the speed polarization abruptly reorients to align with the Mn magnetic moments, leading to an MR ≈ −100%. Abstract Mn3Si2Te6, quasi‐2D ferrimagnetic semiconductor, exhibits anomalous saturated colossal magnetoresistance (CMR) only when a magnetic field is applied along its magnetic hard magnetization axis, suggesting ...

Advanced Science, EarlyView.HmmyCAFs may form a triple immunosuppressive niche: possibly secrete ECM (POSTN, etc.) as physical barriers to block CD8⁺ T cells, induce CD8⁺ T exhaustion via those molecules, and use HIF‐1α‐driven metabolism to create acidic, nutrient‐poor microenvironments that suppress T cells.

Room‐Temperature Ferromagnetism in an Iron‐Based Zeolitic Imidazolate Framework Glass
Advanced Science, EarlyView.Vitrification engineering is employed to induce magnetic ordering transformation from room‐temperature antiferromagnetism of crystalline Fe‐ZIF to weak ferromagnetism of its glassy counterpart. The structure‐magnetism relationships are investigated to provide a valuable guide for tuning magnetic properties and designing of MOFs magnets.

Flash Synthesis of High‐Performance Sub‐Micron Low‐Disorder LiNixCoyAlzO2 Cathode Single Crystals
Advanced Energy and Sustainability Research, EarlyView.A novel and scalable Flash‐Heat and Quench methodology has been developed to synthesize high‐performance LiNi0.8Co0.15Al0.05O2 single crystal cathodes in just minutes versus conventional methods that take multiple hours. X‐ray powder diffraction, neutron powder diffraction, and pair‐distribution and X‐ray absorption spectroscopy have shown low paired ...

Bifurcation theory for Fredholm operators
Journal of Differential EquationsThis paper consists of four parts. It begins by using the authors's generalized Schauder formula, [50], and the algebraic multiplicity, $χ$, of Esquinas and López-Gómez [18,17,40] to package and sharpening all existing results in local and global bifurcation theory for Fredholm operators through the recent author's axiomatization of the Fitzpatrick ...
