Template‐Assisted Growth of CsxFA1‐xPbI3 with Pulsed Laser Deposition for Single Junction Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Template‐assisted pulsed laser deposition (PLD) enables the growth of phase‐pure α‐CsxFA1‐xPbI3 perovskite films. Stoichiometric transfer and uniform coverage on planar and textured substrates is demonstrated, delivering reproducible single‐junction perovskite solar cells.

Cosmological Constraint on $Ω_m$ and $σ_8$ from Cluster Abundances using the $\mathtt{GalWCat19}$ Optical-Spectroscopic SDSS Catalog [PDF]

open access: yes, 2020
We derive cosmological constraints on the matter density, \om, and the amplitude of fluctuations, \sig, using $\mathtt{GalWCat19}$, a catalog of 1800 galaxy clusters we identified in the Sloan Digital Sky Survey-DR13 spectroscopic data set using our GalWeight technique to determine cluster membership \citep{Abdullah18,Abdullah19}.

Exploring consumption profiles, consumer experience and quality claims of Canary Islands' cider (Spain): A multidimensional analysis

open access: yesAgribusiness, EarlyView.
Abstract The exponential expansion of the global cider market positions it as a viable alternative to traditional choices such as wine and beer. Nevertheless, there exists a paucity of research examining the various factors influencing consumer interest in cider.

SIG [PDF]

open access: yesExtended Abstracts of the 2018 CHI Conference on Human Factors in Computing Systems, 2018
Chatbots are emerging as an increasingly important area for the HCI community, as they provide a novel means for users to interact with service providers. Due to their conversational character, chatbots are potentially effective tools for engaging with customers, and are often developed with commercial interests at the core.

Infrared renormalization in non-relativistic QED and scaling criticality [PDF]

open access: yesJournal of Functional Analysis, 254 (10), 2555 - 2647, 2008., 2006
We consider a spin-$\frac12$ electron in a translation-invariant model of non-relativistic Quantum Electrodynamics (QED). Let $H(\vp,\sig)$ denote the fiber Hamiltonian corresponding to the conserved total momentum $\vp\in\R^3$ of the Pauli electron and the photon field, regularized by a fixed ultraviolet cutoff in the interaction term, and an infrared

Sig-SDEs model for quantitative finance [PDF]

open access: yesarXiv, 2020
Mathematical models, calibrated to data, have become ubiquitous to make key decision processes in modern quantitative finance. In this work, we propose a novel framework for data-driven model selection by integrating a classical quantitative setup with a generative modelling approach.

Synchrotron intensity gradients as tracers of magnetic field [PDF]

open access: yes, 2017
On the basis of the modern understanding of MHD turbulence, we propose a new way of using synchrotron radiation, namely using synchrotron intensity gradients for tracing astrophysical magnetic fields. We successfully test the new technique using synthetic data obtained with the 3D MHD simulations and provide the demonstration of the practical utility ...

The Role of Coordination Mechanisms and Transaction Costs Promoting Sustainability Performance in Agri‐Food Supply Chains: Evidence From Ecuador

open access: yesAgribusiness, EarlyView.
ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.
