Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Bounded solutions of nonlinear parabolic equations
Electronic Journal of Differential Equations, 2010 We are concerned with bounded solutions existing for all times for nonlinear parabolic equations with possibly nonlinear boundary conditions. A counterexample shows that, without an additional condition, a (weak) maximum principle does not hold for ...

On stability of nonlinear difference equations and some of their applications
Қарағанды университетінің хабаршысы. Математика сериясыThe issues of stability in solving nonlinear difference equations were considered. Based on a generalized difference analog of the well-known Bihari lemma, stability conditions for a trivial solution based on initial data were obtained, and an a priori ...

Interacting Parallel Fluidic Hysterons. [PDF]
Adv Sci (Weinh)The parallel coupling of fluidic hysterons is introduced, establishing advanced functionalities in inflatable soft systems. A pressure–volume framework reveals how preset volumes Δv∗${\Delta }v^*$ tune nonlinear interactions between hysterons and actuation sequences without changing architecture. Experiments validate the predictions, opening new routes

A dynamical inverse problem for a parabolic equation [PDF]
Opuscula Mathematica, 2006 A problem of dynamical reconstruction of unknown distributed or boundary disturbances acting upon nonlinear parabolic equations is discussed. A regularized algorithm which allows us to reconstruct disturbances synchro with the process under consideration

ESC Heart Failure, Volume 12, Issue 2, Page 859-868, April 2025.Abstract Aims Natriuretic peptide‐based pre‐heart failure screening has been proposed in recent guidelines. However, an effective strategy to identify screening targets from the general population, more than half of which are at risk for heart failure or pre‐heart failure, has not been well established.

The Feasibility Test of Electric Propulsion Systems: Case Study for a Light and Fixed‐Wing Aircraft
Energy Science &Engineering, EarlyView.ABSTRACT This study investigates the feasibility and performance of a fully electric propulsion system (EPS) integrated into a light fixed‐wing aircraft. The system consists of a 65 kW‐class electric motor, a high‐efficiency inverter, and dual lithium‐ion battery packs with a total capacity of 27 kWh—collectively engineered to fulfill both power ...

Finite element multistep multideriavative schemes for parabolic equations [PDF]
, 1976 The linear, homogeneous, parabolic equation is solved by applying finite element discretizations in space and A0 —stable, linear multistep, multiderivative (L.M.S.D.) methods in time. Such schemes are unconditionally stable. An error analysis establishes

Effect of Microchannel Geometry on Nanoparticle Deposition in Nanofluid Flow
International Journal for Numerical Methods in Fluids, EarlyView.This study numerically analyzed nanoparticle deposition in microchannels with varying geometries. Deposition per unit area decreases significantly with increasing bend angle (28.612 to 8.941 between 30° and 120°) and bend radius (11.922 to 4.769 between 0.2 and 0.4 mm). Acute bends and small radii enhance centrifugal forces and flow separation, leading
