Boyanov-Naydenov problem and Kolmogorov type inequalities for positive (negative) parts of functions
Researches in MathematicsWe prove that Boyanov-Naidenov problem $\|x^{(k)}_{\pm}\|_{q,\, \mu} \to \sup$ on classes of functions $\Omega^r_p(A_0, A_r):=\{x\in L^r_{\infty}: \|x^{(r)}\|_{\infty}\le A_r, L(x)_p\le A_0 \}$, where $k= 0,1,...,r-1$, $q \ge 1$ for $k\ge 1$, $q \ge p ...

Advanced Engineering Materials, EarlyView.Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

BMJ Open, 2019 Background Ageing patients are discharged from the hospital ‘quicker and sicker’ than before, and hospital discharge is a critical step in patient care. Older patients form a particularly vulnerable group due to multimorbidity and frailty.

Tikhonov well-posedness and differentiability on asymmetrically normed spaces
Quaestiones MathematicaeOn normed vector spaces there is a well-known connection between the Tikhonov well-posedness of a minimisation problem and the differentiability of an associated convex conjugate function. We show how this duality naturally generalises to the setting of asymmetrically normed spaces and prove a universal differentiability property of the convex ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Bishop-Phelps Theorem for Normed Cones
پژوهشهای ریاضی, 2019 Introduction In the last few years there is a growing interest in the theory of quasi-metric spaces and other related structures such as quasi-normed cones and asymmetric normed linear spaces, because such a theory provides an important tool in the study

"A Change of Paradigm" in Developing Land Forces Officers' Professional Skills in Accordance with Hybrid Warfare Task-Requirements [PDF]
Journal of Defense Resources Management, 2016 In future conflicts, not only traditional or asymmetric actions will be used, but also a combination of the two in order to solve the disputes involving national and international actors, materialized today in different manifestation forms called ...

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Modulational Instability and Dynamical Growth Blockade in the Nonlinear Hatano–Nelson Model
Advanced Physics ResearchThe Hatano–Nelson model is a cornerstone of non‐Hermitian physics, describing asymmetric hopping dynamics on a 1D lattice, which gives rise to fascinating phenomena such as directional transport, non‐Hermitian topology, and the non‐Hermitian skin effect.
