Advanced Materials Technologies, EarlyView.Mesoscopic carbon‐based perovskite solar cells (C‐PSCs) offer a pathway to stable, scalable, low‐cost photovoltaics via commercially mature fabrication methods. While their potential lifespan has been demonstrated under standardized conditions, few studies examine the behavior of large‐area modules exposed to real‐world environments. Here, 12 months of

Restricted partitions and convex topologies
AIMS MathematicsLet $ X_{n} $ be a finite set. We consider two types of sequences of restricted partitions of $ X_n $, namely, the number of order consecutive partitions of $ X_{n} $ into $ k $ parts, denoted $ N_{oc}(n, k) $ and the sequence $ T(n, k) $ of the number ...

On the spectral norms of r-circulant matrices with the biperiodic Fibonacci and Lucas numbers
Journal of Inequalities and Applications, 2017 In this paper, we present new upper and lower bounds for the spectral norms of the r-circulant matrices Q=Cr((ba)ξ(1)2q0,(ba)ξ(2)2q1,(ba)ξ(3)2q2,…,(ba)ξ(n)2qn−1) $Q=C_{r} ( (\frac{b}{a} )^{\frac{\xi (1)}{2}}q_{0}, (\frac{b}{a} )^{\frac{\xi(2)}{2}}q_{1}, (

The open-loop solution of the Uzawa-Lucas Model of Endogenous Growth with N agents [PDF]
We solve an N 2 N player general-sum differential game. The optimization problem considered here is based on the Uzawa Lucas model of endogenous growth. Agents have logarithmic preferences and own two capital stocks.

Advanced Optical Materials, EarlyView.This study reports the synthesis, structure, and optical properties of (pr‐ted)2[MnBr4], a luminescent manganese (II) hybrid halide. It shows green emission under UV and transforms into a red‐emitting hydrated phase with humidity, reversible by heat or vacuum. Structural, photophysical, and theoretical analyses confirm the mechanism.

On the independent subsets of powers of paths and cycles
, 2012 In the first part of this work we provide a formula for the number of edges of the Hasse diagram of the independent subsets of the h-th power of a path ordered by inclusion. For h=1 such a value is the number of edges of a Fibonacci cube.

Advanced Robotics Research, EarlyView.Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Melham's Conjecture on Odd Power Sums of Fibonacci Numbers
, 2015 Ozeki and Prodinger showed that the odd power sum of the first several consecutive Fibonacci numbers of even order is equal to a polynomial evaluated at certain Fibonacci number of odd order.
