Development of a Novel Superhydrophobic Sawdust–Perspex Composite Disc for Efficient Oil–Water Separation

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water pollution by oil and organic substances causes serious problems that threaten the ecosystem. Superhydrophobic materials represent an effective solution for removing oil from water. The present paper investigates the development of a low‐cost, superhydrophobic composite for oil–water separation.

Gleaning the Rocky Shore? 2500 Years of Coastal Resource Use at Red Bluff 1, GunaiKurnai Country, SE Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Adaptive mixing formation control of multiquadrotor unmanned aerial vehicle systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a distributed adaptive mixing control (AMC) design for formation maintenance of systems of multiquadrotor UAVs (q‐UAVs) during commanded path‐tracking maneuvers. The proposed formation control scheme has a two‐level structure. The high level defines the desired trajectories for rigid and persistent formation acquisition and

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Discrete Element Method Modeling of an Extrusion Process with Recirculation for Dry Manufacturing of Lithium‐Ion Battery Electrodes

Batteries &Supercaps, EarlyView.
On a digitized laboratory extruder, discrete element method modelling is studied, considering two classes of particles representing aggregates of 1) active material and 2) binder and carbon material is studied. Various extrusion scenarios leading to the formation of filaments devoted to the 3D printing of lithium‐ion battery electrodes are studied. The

Dynamics of a class of uncertain nonlinear systems under flow-invariance constraints

International Journal of Mathematics and Mathematical Sciences, 2003
For a class of uncertain nonlinear systems (UNSs), the flow-invariance of a time-dependent rectangular set (TDRS) defines individual constraints for each component of the state-space trajectories.

Global asymptotic stability in a periodic integro-differential system

Tohoku Mathematical Journal, 1985
This paper deals with generalized Lotka-Volterra equations of the form \[ dx_ i(t)/dt=x_ i(t)\{b_ i(t)-a_{ii}(t)x_ i(t)- \sum^{n}_{j=1,j\neq i}a_{ij}(t)\int^{t}_{-\infty}K_{ij}(t- u)x_ j(u)du\}, \] i\(=1,2,...,n\); \(t>t_ 0\); \(t_ 0\in (- \infty,\infty)\) in which \(b_ i\), \(a_{ij}\) \((i,j=1,2,...,n)\) are continuous, periodic, and positive.

Model‐informed drug development to support nemolizumab clinical development in adults and adolescents with moderate to severe atopic dermatitis

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aims Population pharmacokinetic (popPK) and pharmacokinetic‐pharmacodynamic (PK/PD) models were developed to support clinical development of nemolizumab, a humanized monoclonal antibody targeting the IL‐31 receptor α, in adolescents and adults with moderate‐to‐severe atopic dermatitis (AD).

Global stability of Hopfield neural networks under dynamical thresholds with distributed delays

Discrete Dynamics in Nature and Society, 2006
We study the dynamical behavior of a class of Hopfield neural networks with distributed delays under dynamical thresholds. Some new criteria ensuring the existence, uniqueness, and global asymptotic stability of equilibrium point are derived.

Innovation Pathways to Carbon Efficiency: Disentangling the Effects of AI, R&D, and Clean Energy Blessings on U.S. Environmental Sustainability

Business Strategy and the Environment, EarlyView.
ABSTRACT The United States (U.S.) faces challenges in achieving its ambitious net‐zero carbon emissions target by 2050, with current emissions having fallen by less than 1% in 2024. Despite an investment of $500 billion in low‐carbon resources while holding the second‐largest green technology patent portfolio globally, it is further imperative to ...
