ON GAUSSIAN FUZZY LUCAS NUMBERS

Journal of Science and Arts
In the present paper, we introduce a new class of fuzzy numbers, which we will call Gaussian fuzzy Lucas numbers. We establish some fundamental properties and identities for these newly defined numbers, including the recurrence relation, Binet’s formula, generating function, summation formula, and Vajda’s identity, as special cases, Catalan’s identity,

Mechanical Flexibility Enables DNA Origami to Overcome Steric Confinement in Mucus

Advanced Science, EarlyView.
Mechanical flexibility is introduced as a design parameter to enhance nanocarrier transport in mucus. Using DNA origami, flexibility is decoupled from size, shap and surface chemistry, revealing improved passage through confined hydrogel networks. While surface passivation reduces aggregation, flexibility further boosts transport, offering a general ...

Bistable Networks Enable Complex Shape Changes

Advanced Science, EarlyView.
Transition‐controlled metamaterials are networks of bistable mechanical memory that store local binary states and express them as global shape change. By decoupling low‐force programming from high‐force holding, a single lattice is reconfigured into distinct 2D profiles and 3D surfaces without continuous actuation, enabling reusable morphing materials ...

Enriched and Sustained Oxygen Vacancies in Amorphous NiWOx Enhance and Stabilize Urea Electrooxidation

Angewandte Chemie, EarlyView.
We propose an “amorphous oxygen mechanism (AOM)” for urea electrooxidation on amorphous NiWOx with tunable Ov, which achieves robust UOR activity and stability simultaneously. The “amorphous oxygen” in NiWOx prefers to escape during the UOR, in situ generating and stabilizing Ov, which thermodynamically promotes the reaction.

Effects of Doping, Disorder, and Compensation on Electron Conduction in Si‐Doped k‐Ga2O3 Close to the Metal‐to‐Insulator Transition

Advanced Electronic Materials, EarlyView.
Self‐compensation effects attributed to doping‐dependent shift‐defects at APBs Validation of Hall data for VRH transport near the MIT Persistence of VRH transport for any SiH4 flow in Si‐doped κ‐Ga2O3 due to high compensation coupling transport and EPR data as strategy to study electronic properties and doping T‐dependence of transport data agrees with

Fibonacci and Lucas numbers close to Narayana's cows numbers

Researches in Mathematics
In this study, we find all Fibonacci and Lucas numbers which are close to Narayana's cows numbers. The main tools used in this work are lower bounds for linear forms in logarithms due to Matveev and Dujella-Pethö version of the Baker-Davenport reduction ...

A Critical Assessment of Bonding Descriptors for Predicting Materials Properties

Advanced Intelligent Discovery, EarlyView.
The impact of new bonding descriptors in machine learning models for predicting material properties is assessed. Improvements are validated using significance tests, and new, intuitive descriptors for screening lattice thermal conductivity and projected force constants are introduced.

Lost in aggregation? On the importance of local food price data for food poverty estimates

American Journal of Agricultural Economics, EarlyView.
Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

Immigrant mental health, safe work, discrimination, and state policies: From racism and xenophobia to health equity

American Journal of Community Psychology, EarlyView.
Abstract An ecological model was developed to examine the pathways linking immigration state policies to physically safe work conditions and work volition, interpersonal discrimination, and mental health distress. The ecological framework was tested among two subsamples totaling 529 Latinx immigrant participants: (1) immigrants who resided in states ...
