Research Paper: Effect of Mn Substitution for Fe on the Supercapacitive Performance of Cobalt Ferrite Nanoparticles [PDF]

open access: yesفیزیک کاربردی ایران
In this study, the effect of Mn substitution on the structural and electrochemical properties of cobalt ferrite nanoparticles (CoFe2-xMnₓO₄; x = 0.0, 0.1, 0.3, 0.5) was investigated for supercapacitor applications.

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Efficient Access To 3-substituted-gamma-hydroxylactams: The Uncatalyzed Addition Of Diorganozinc Reagents To Cyclic Imides With Heterocyclic Substitution [PDF]

open access: yes, 2014
A range of 3-substituted-gamma-hydroxylactams have been prepared via the uncatalyzed addition of organo-zinc nucleophiles to cyclic imides. This reactivity is primarily limited to imides containing heterocyclic N-substitution, but proceeds efficiently ...

Dipolar addition to cyclic vinyl sulfones leading to dual conformation tricycles

open access: yesBeilstein Journal of Organic Chemistry, 2013
Dipolar addition of cyclic azomethine imines with cyclic vinyl sulfones gave rise to functionalized tricycles that exhibited fluxional behavior in solution at room temperature.

Substituents Regulate the Cyclization of Conjugated Alkynes to Accurately Construct Cyclo-(E)-[3]dendralenes

open access: yesMolecules, 2023
Substituent-regulated cyclization of conjugated alkynes with acid catalysis was developed in this paper, and it provides a straightforward synthesis of cyclic-(E)-[3]dendralenes.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Stress-Strain Analysis of Cyclic Plastic Bending and Torsion [PDF]

open access: yes, 1978
Analysis of stresses, strains, and damping energies is considered for cyclic loading of simple geometries. For beams under pure bending and for circular shafts under torsion, it is shown that cyclic loading may be handled by analysis that differs from ...

Binding-Pocket and Lid-Region Substitutions Render Human STING Sensitive to the Species-Specific Drug DMXAA

open access: yesCell Reports, 2014
The drug DMXAA (5,6-dimethylxanthenone-4-acetic acid) showed therapeutic promise against solid tumors in mouse models but subsequently failed in human clinical trials. DMXAA was later discovered to activate mouse, but not human, STING, an adaptor protein

Admissibility of Substitution Rule in Cyclic-Proof Systems

open access: yesCoRR
This paper investigates the admissibility of the substitution rule in cyclic-proof systems. The substitution rule complicates theoretical case analysis and increases computational cost in proof search since every sequent can be a conclusion of an instance of the substitution rule; hence, admissibility is desirable on both fronts. While admissibility is
