Multiple periodic solutions for second order Josephson-type differential systems
Boundary Value Problems, 2017 In this paper, some new existence theorems are obtained for multiple periodic solutions of second order Josephson-type differential systems with partially periodic potential by using the minimax methods in critical point theory, which generalize and ...

Computation of Generalized Inverses of Periodic Systems
, 2004 We address the numerically reliable computation of generalized inverses of periodic systems. The underlying inverses are defined via the corresponding lifted repesentations.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

$M$-periodic problem of order $2k$
Topological Methods in Nonlinear Analysis, 1998 The author gives sufficient conditions for the existence of solutions to some general matrix-periodic problems of higher even order, which have a variational structure. A key tool in the proofs is a generalization of the Du Bois-Reymond lemma for periodic functions of order one, which was proved by the author in a previous work [Gȩba, Kazimierz (ed ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Time-periodic corner states from Floquet higher-order topology
Nature Communications, 2022 A combination of Floquet engineering and higher-order topological insulators has been lately only theoretically proposed. Here the authors experimentally realize an acoustic waveguides array to demonstrate a Floquet higherorder topological insulator ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

The periodic problem for the second order integro-differential equations with distributed deviation [PDF]
, 2021 summary:We study the question of the unique solvability of the periodic type problem for the second order linear integro-differential equation with distributed argument deviation $$ u''(t)=p_0(t)u(t)+\int _{0}^{\omega }p(t,s)u(\tau (t,s)) {\rm d}s+ q(t),
