Technological Progress and Obsolescence: Analyzing the Environmental Economic Impacts of MacBook Pro I/O Devices [PDF]

arXiv
This study investigates how the new release of MacBook Pro I/O devices affects the obsolescence of related accessories. We also explore how these accessories will impact the environment and the economic consequences. As technology progresses, each new MacBook Pro releases outdated prior accessories, making more electronic waste.

Uniformizing differential equations of arithmetic (1;e)-groups [PDF]

arXiv, 2012
We present a numerical method to compute accessory parameters of the uniformizing differential equations of elliptic curves associated to arithmetic Fuchsian $(1;e)$ groups. Up to $PSL_2(\bbr)$ conjugation there are only finitely many such groups and we give a complete list of the accessory ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells

Advanced Materials, EarlyView.
Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

High‐Performance Electrocatalysts of Potassium Lactate Oxidation for Hydrogen and Solid Potassium Acetate Production

Advanced Materials, Volume 37, Issue 13, April 2, 2025.
Potassium lactate, produced from polylactic acid plastic waste, is oxidized to potassium acetate on an anode using Ni(Co)OOH as the electrocatalyst, while hydrogen is simultaneously generated at the cathode, through a highly efficient industrial‐scale electrolysis system.

Permanent junctional reciprocating tachycardia in a patient with an atypically located accessory pathway in the left lateral mitral annulus

Revista Portuguesa de Cardiologia, 2016
Permanent junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular reentrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction.

Wolf–Parkinson–White Syndrome: Diagnosis, Risk Assessment, and Therapy—An Update

Diagnostics
Wolf–Parkinson–White (WPW) syndrome is a disorder characterized by the presence of at least one accessory pathway (AP) that can predispose people to atrial/ventricular tachyarrhythmias and even sudden cardiac death.

Radiofrequency Catheter Ablation of Parahisian Accessory Pathway

Journal of Interdisciplinary Medicine, 2016
Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block.

Mechanistic Insights Into Proton and Oxygen Transport Through Ultrathin Amorphous Al2O3 and Al2O3‐SiO2 Electrocatalyst Overlayers

Advanced Materials Interfaces, EarlyView.
Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.

Prices and preferences in the electric vehicle market [PDF]

arXiv
Although electric vehicles are less polluting than gasoline powered vehicles, adoption is challenged by higher procurement prices. Existing discourse emphasizes EV battery costs as being principally responsible for this price differential and widespread adoption is routinely conditioned upon battery costs declining.
