Quantifying Structure‐Dependent Rigidity of 3D DNA Origami Boxes

Advanced Intelligent Systems, EarlyView.
We investigate the mechanical stability of a hollow 3D DNA origami box during assembly using liquid AFM imaging and finite element simulations. As structural completeness increases from flat sheets through intermediate assemblies to a closed box, rigidity improves.

Revealing Hidden Raman Signatures Through Attention‐Based Spectral Unmixing

Advanced Intelligent Systems, EarlyView.
Weak Raman signatures are recovered from background‐dominated spectra using a transformer‐based, reference‐free spectral unmixing AI framework. Self‐attention reconstructs substrate contribution directly from mixed data, enabling reliable extraction of previously inaccessible vibrational features.

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

On Efficient Iterative Algorithms and Conditioning for the Nonlinear Sylvester Equation

Computational and Mathematical Methods
Nonlinear Sylvester-type matrix equations arise in applications such as control theory, observer design, model reduction, and data-driven systems, where they model higher order interactions in matrix transformations.

Convergence and Stability Improvement of Quasi-Newton Methods by Full-Rank Update of the Jacobian Approximates

AppliedMath
A system of simultaneous multi-variable nonlinear equations can be solved by Newton’s method with local q-quadratic convergence if the Jacobian is analytically available.

Backward Step Control for Global Newton-Type Methods

SIAM Journal on Numerical Analysis, 2016
Summary: We present and analyze a new damping approach called backward step control for the globalization of the convergence of Newton-type methods for the numerical solution of nonlinear root-finding problems. We provide and discuss reasonable assumptions that imply convergence of backward step control on the basis of generalized Newton paths in ...

The Legislation for Providing Animal Access in Australian Residential Aged Care: It's Not a Zoo

Australian Journal of Social Issues, EarlyView.
ABSTRACT Providing meaningful animal contact to residential aged care facility (RACF) residents is problematic due to a lack of animal policies and National Guidelines. This paper examines how Australian Legislation could influence access to animal contact in RACFs and aims to answer the question, ‘Could current Legislation facilitate the development ...

Refining OVCAR‐3 xenograft models of peritoneal carcinomatosis in nu/nu mice: Comparative intraperitoneal implantation strategies and the role of basement membrane matrix

Animal Models and Experimental Medicine, EarlyView.
A refined murine model of advanced ovarian cancer was established by comparing localized preperitoneal implantation and intraperitoneal injection of OVCAR‐3Luc cells. While localized implantation showed limited tumor persistence, intraperitoneal delivery with BME produced sustained diffuse dissemination confirmed by BLI and histology, providing a ...

c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis

Hepatology, EarlyView., 2022
In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.
