Measures and the Law of the Iterated Logarithm

open access: yes, 2009
Let m be a unidimensional measure with dimension d. A natural question is to ask if the measure m is comparable with the Hausdorff measure (or the packing measure) in dimension d.

Hybrid Solar Spectral‐Splitting Photovoltaic‐Thermal Hydrogen Production Systems

open access: yesAdvanced Science, EarlyView.
A hybrid solar photovoltaic‐thermal hydrogen system with membrane‐less electrolysis significantly boosts solar‐to‐hydrogen efficiency by co‐using thermal and electrical energy. The system attains good performance under variable irradiance with direct current power converters.

A general law of the iterated logarithm for non-additive probabilities

open access: yesResults in Applied Mathematics
Motivated by some interesting problems in mathematical economics, quantum mechanics and finance, non-additive probabilities have been used to describe the phenomena which are generally non-additive. In this paper, we further study the law of the iterated

SIMECK-T: An Ultra-Lightweight Encryption Scheme for Resource-Constrained Devices

open access: yesApplied Sciences
The Internet of Things produces vast amounts of data that require specialized algorithms in order to secure them. Lightweight cryptography requires ciphers designed to work on resource-constrained devices like sensors and smart things.

Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

AI‐Driven Defecation Analysis by Smart Healthcare Toilet: Exploring Biometric Patterns and Eu‐Tenesmus

open access: yesAdvanced Science, EarlyView.
A healthcare toilet system is introduced to passively measure defecation behavior. Real‐time data on stool dropping duration, thickness, and a newly defined “eu‐tenesmus” interval show correlations with stool form and gender differences. Results from 45 defecation events reveal a promising method for comprehensive defecation analysis.

Stacking Interventions Enhances Carbon Removals and Profitability of Livestock Production Systems

open access: yesAdvanced Science, EarlyView.
The study indicates that stacking multiple interventions aimed at maximising soil organic carbon (SOC) sequestration and enteric methane (CH4) reductions realizes greater abatement and profit do any singular intervention, especially when SOC sequestration accounts for a significant proportion of greenhouse gas emissions (GHG) mitigation. Abstract While
