Patents and Supra‐Competitive Prices: Evidence From Consumer Products

open access: yesJournal of Empirical Legal Studies, Volume 23, Issue 2, Page 172-204, June 2026.
ABSTRACT A patent system is a central tool in innovation policy. The prospect of monopolistic pricing supposedly encourages firms to innovate. However, there is scant empirical evidence supporting the existence of higher markups for patent‐protected products.

M1 a‐tDCS does not acutely enhance motor skill acquisition of a dexterous, timing‐based videogame task in adults

open access: yesPhysiological Reports, Volume 14, Issue 12, June 2026.
Abstract Motor skill acquisition involves plastic changes across distributed neural networks, and anodal transcranial direct current stimulation (a‐tDCS) applied over primary motor cortex (M1) is often used to modulate excitability and potentially enhance learning.

Analyses of Deformation and Stress of Oil-free Scroll Compressor Scroll

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
The solid model of orbiting and fixed scroll is created by the Solidworks The deformation and stress of scrolls under gas force, temperature field, inertia force and the coupling field are analyzed using the Ansys software. The deformation for different thickness and height scroll tooth is investigated.

Optimization of line control parameters for scroll compressors with variable base circle involute

open access: yesZhileng xuebao
Because the volume of the variable base circular involute scroll compressor can be reduced under the premise of obtaining the same cooling capacity, it can meet the small and lightweight requirements of the vehicle air conditioning compressor.
