On a Dual Pair of Multiobjective Interval-Valued Variational Control Problems

open access: yesMathematics, 2021
In this paper, by using the new concept of (ϱ,ψ,ω)-quasiinvexity associated with interval-valued path-independent curvilinear integral functionals, we establish some duality results for a new class of multiobjective variational control problems with ...

(0,2) Duality [PDF]

open access: yesAdvances in Theoretical and Mathematical Physics, 2003
We construct dual descriptions of (0,2) gauged linear sigma models. In some cases, the dual is a (0,2) Landau-Ginzburg theory, while in other cases, it is a non-linear sigma model. The duality map defines an analogue of mirror symmetry for (0,2) theories. Using the dual description, we determine the instanton corrected chiral ring for some illustrative

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Sufficient optimality criteria and duality for multiobjective variational control problems with B-(p,r)-invex functions [PDF]

open access: yesOpuscula Mathematica, 2014
In this paper, we generalize the notion of \(B\)-\((p,r)\)-invexity introduced by Antczak in [A class of \(B\)-\((p; r)\)-invex functions and mathematical programming, J. Math. Anal. Appl. 286 (2003), 187-206] for scalar optimization problems to the case

DUALITY AND DILATON

open access: yesModern Physics Letters A, 1991
We review and elaborate on the issue of the dilaton transformation under the usual r → α′/r target space duality and its "non-static" generalization (or σ-model duality). It is found that the transformation law r → α′/r, [Formula: see text] which guarantees duality at the one-loop σ-model level should be modified at two (and higher) loop order.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Optimality and duality for nonsmooth semi-infinite E-convex multi-objective programming with support functions

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2020
In this paper, we study a nonsmooth semi-infinite multi-objective E-convex programming problem involving support functions. We derive sufficient optimality conditions for the primal problem.

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.

Monuments and monumentality: the cosmological model of the world of megaliths

open access: yesDocumenta Praehistorica, 2010
Neolithic monuments are physical and conceptual expressions of ideas about the nature of the world inhabited by early north European farmers. This contribution explores the complex symbolism encoded in megalithic architecture, and the socio-ritual ...
