Deterministic epidemic models overestimate the basic reproduction number of observed outbreaks

open access: yesInfectious Disease Modelling
The basic reproduction number, R0, is a well-known quantifier of epidemic spread. However, a class of existing methods for estimating R0 from incidence data early in the epidemic can lead to an over-estimation of this quantity.

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Analysis of accuracy of Williams series approximation of stress field in cracked body – influence of area of interest around crack-tip on multi-parameter regression performance

open access: yesFracture and Structural Integrity, 2016
A study on the accuracy of an approximation of the stress field in a cracked body is presented. Crack-tip stress tensor is expressed using the linear elastic fracture mechanics (LEFM) theory in this work, more precisely via its multi-parameter ...

Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

open access: yesAdvanced Materials, EarlyView.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Light‐Induced Entropy for Secure Vision

open access: yesAdvanced Materials, EarlyView.
This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

Estimation of multi-state life table functions and their variability from complex survey data using the SPACE Program [PDF]

open access: yes
The multistate life table (MSLT) model is an important demographic method to document life cycle processes. In this study, we present the SPACE (Stochastic Population Analysis for Complex Events) program to estimate MSLT functions and their sampling ...

Stoichiometry‐Programmed MXenes via Precursor Engineering for High‐Performance EMI Shielding and Energy Storage

open access: yesAdvanced Materials, EarlyView.
Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

A deterministic and probabilistic framework based on corrected wind speed to improve Short-Term wind power forecasting accuracy

open access: yesInternational Journal of Electrical Power & Energy Systems
The safety and stability of power systems with high wind power penetration are challenged by the inherent variability and uncertainty of wind generation. To improve short-term wind power forecasting accuracy, this study proposes a novel deterministic and

Analog Control of Reconfigurable GHz Resonances from Chiral Spin Texture Ensembles

open access: yesAdvanced Materials, EarlyView.
Tunable microwave components ‐ essential for wireless technology ‐ typically require costly, customized nanofabrication. We show that ambient spin texture ensembles (e.g., magnetic skyrmions) in chiral multilayer films can enable reconfigurable microwave resonators.
