Laser‐Synthesized Amorphous PdSe2‐x Nanoparticles: A Defect‐Rich Platform for High‐Efficiency SERS, Photocatalysis, and Photothermal Conversion

open access: yesAdvanced Materials Interfaces, EarlyView.
Using femtosecond ablation, we show that an ordered, stoichiometric crystalline PdSe2 target can be controllably converted into a stable, disordered, non‐stoichiometric, and highly functional amorphous nanomaterial, PdSe2−x${\rm PdSe}_{2-x}$. The obtained nanoparticles offer significant advantages over conventional planar plasmon‐free substrates due to

Discrete dynamics of complex systems

open access: yesDiscrete Dynamics in Nature and Society, 1997
This article extends the slaving principle of synergetics to processes with discrete time steps. Starting point is a set of nonlinear difference equations which contain multiplicative noise and which refer to multidimensional state vectors.

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

The Problem of Implementing the Systematic Synergetic Approach in Pedagogy

open access: yesОбразование и наука, 2015
The paper discusses the opportunities and limitations of using the systematic synergetic approach to pedagogical research. The main emphasis is on the adaptation of synergetic ideas, as a new cognitive model in educational content, and application of its

Nonlocal control of pulse propagation in excitable media

open access: yes, 2014
We study the effects of nonlocal control of pulse propagation in excitable media. As a generic example for an excitable medium the FitzHugh-Nagumo model with diffusion in the activator variable is considered. Nonlocal coupling in form of an integral term

Organic Bulk‐Heterojunction‐Integrated Flexible Perovskite Photodetection Arrays for High‐Speed Broadband Optical Communication

open access: yesAdvanced Science, EarlyView.
A flexible broadband photodetector is realized by integrating a perovskite with an organic bulk‐heterojunction. It achieves high external quantum efficiency (EQE) (>80% visible, >60% near‐infrared (NIR)), ultralow dark current, and fast response, enabling self‐powered, high‐detectivity operation.

UNCERTAINTY, CHANGEABILITY AND INCONSISTENCY IN TASKS OF ANALYZING RISKS OF ECONOMIC SYSTEM BEHAVIOR

open access: yesСтратегические решения и риск-менеджмент, 2014
The theorem of ultimate uncertainty of a complex economic system states that the social-economical process of a complex economic system functioning develops efficiently if complexity and manageability characteristics are similar, and manageability ...

Elemene Augments the Effects of Anti‐PD‐1 Immunotherapy on Hepatocellular Carcinoma by Regulating the miR‐130a‐5p/SPP/MHC‐I Axis

open access: yesAdvanced Science, EarlyView.
Elemene increases SPP expression by competitively binding with miR‐130a‐5p to suppress SPP mRNA degradation. This led to more antigen/MHC‐I complexes being expressed on the cell surface, which consequently facilitated the recognition and killing of HCC cells by CTLs and enhancing the antitumor immune efficacy of anti‐PD‐1.

PDIA3 Inhibition Facilitates Sensitivity of IKE‐Induced Ferroptosis via STAT3/LCN2 Axis to Improve Glioblastoma Therapy

open access: yesAdvanced Science, EarlyView.
In this manuscript, protein disulfide isomerase A3 (PDIA3) is identified as a key factor mediating the susceptibility of ferroptosis in GBM. Inhibition of PDIA3 enhances IKE or cystine starvation‐induced ferroptosis in GBM cells by resulting in the accumulation of lipid peroxidation and a reduction in GSH level.
