Intrinsic Coupling of Radiative Cooling and Triboelectric Responses in Dual‐Function ZrO2 Nanocomposites for Adaptive Thermoregulation

Advanced Science, EarlyView.
A novel nanocomposite design strategy utilizes ZrO2 to intrinsically couple passive daytime radiative cooling and triboelectric functionality within a single material platform. Fabricated via direct ink writing, the multifunctional breathable architecture provides effective sub‐ambient cooling, motion‐driven energy harvesting, and adaptive ...

Some Common Fixed Point Theorems in Partially Ordered Sets

Journal of Applied Mathematics, 2020
The purpose of this paper is to prove some new fixed point theorem and common fixed point theorems of a commuting family of order-preserving mappings defined on an ordered set, which unify and generalize some relevant fixed point theorems.

Mapping Frictions Inhibiting Bicycle Commuting [PDF]

ISPRS International Journal of Geo-Information, 2018
Urban cycling is a sustainable transport mode that many cities are promoting. However, few cities are taking advantage of geospatial technologies to represent and analyse cycling mobility based on the behavioural patterns and difficulties faced by cyclists.

Fundamental Challenges, Physical Implementations, and Integration Strategies for Ising Machines in Large‐Scale Optimization Tasks

Advanced Electronic Materials, EarlyView.
Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Adapting to Changing Rainfall and Developing Off‐Farm Employment: Implications for the Adoption of Direct Seeding in Rice Production

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Rice is the main staple food for more than half of the world's population and the income from rice is an essential source for livelihoods of millions of households. We examine whether direct seed in rice production is an adaptation of rice farmers to rainfall changes and farm labor scarcity.

Common Fixed Point Theorems on Weakly Contractive and Nonexpansive Mappings

Fixed Point Theory and Applications, 2008
A family of commuting nonexpansive self-mappings, one of which is weakly contractive, are studied. Some convergence theorems are established for the iterations of types Krasnoselski-Mann, Kirk, and Ishikawa to approximate a common fixed point. The error

Commutativity preserving maps revisited

Israel Journal of Mathematics, 2007
The author refines some results of \textit{K. I. Beidar} and \textit{Y.-F. Lin} [Proc. R. Soc. Edinb., Sect. A, Math. 134, No. 6, 1023-1040 (2004; Zbl 1074.16019)] on the structure of commutativity preserving maps. Given any additive map of rings \(\alpha\colon A\to B\), set \(F(x)=[\alpha(x^2),\alpha(x)]\).

Measuring Nutrition Security Using the Consumer Food Data System Datasets

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Nutrition security is an emerging concept lacking a consensus definition, conceptualization, or standardized measure. This perspectives manuscript synthesizes findings from two previously published analyses to assess the feasibility of using available measures of key dimensions of nutrition security from two Consumer Food Data System (CFDS ...

Fixed point results of Altman integral type mapping in S-metric spaces

International Journal of Analysis and Applications, 2016
In this article, we introduce the concept of ϕ-weakly commuting self-mappings pairs in $S$-metric space. Using this idea we establish a common fixed point theorem of Altman integral type for four self-mappings in the context of $S$-metric space.

A general unique common fixed point theorem for hybrid pairs of mappings in metric spaces [PDF]

Surveys in Mathematics and its Applications, 2016
The purpose of this paper is to prove a general unique common fixed point theorem for two pairs of mappings using Hausdorff - Pompeiu metric, which generalizes, in a correct form, the results from [H. Bouhadjera, A. Djoudi and B.
