Iterative Reconstruction Excursions for Baryon Acoustic Oscillations and Beyond

, 2022
The density field reconstruction technique has been widely used for reco v ering the baryon acoustic oscillation (BAO) feature in galaxy surv e ys that has been degraded due to non-linearities. Recent studies advocated adopting iterative steps to impro v

Is It Real Type‐II or S‐Scheme? A Three‐Phase Diagnostic Protocol for Identifying Potentially Mislabeled Heterojunction Photocatalysts

Advanced Functional Materials, EarlyView.
Diagnostic analysis via the heterojunction validation funnel. The funnel illustrates the hierarchical stratification of 30 reported Type‐II systems based on the three‐phase, seven‐step diagnostic framework. Complete validation through all phases is achieved by only 3.3% of systems, while 96.7% lack full mechanistic validation, revealing a pervasive ...

Deep iterative reconstruction estimation (DIRE): approximate iterative reconstruction estimation for low dose CT imaging

, 2019
International audienceThe image quality in low dose computed tomography (LDCT) can be severely degraded by amplified mottle noise and streak artifacts. Although the iterative reconstruction (IR) algorithms bring sound improvements, their high computation

Coupling Anodic Activity and Stability at Ni‐Based Non‐Oxide Catalysts via Coordinating Alcohol Oxidation and Oxygen Evolution

Advanced Functional Materials, EarlyView.
A cooperative and competitive interrelationship between alcohol oxidation (AOR) and water oxidation (OER) was observed on a typical anode catalyst of Ni2P. In situ Raman spectroscopy and electrochemical analyses revealed a specific complementary mechanism between them, in which OER and AOR critically contribute to the activity and stability of anodic ...

Convergence of iterative image reconstruction algorithms for Digital Breast Tomosynthesis

, 2012
Most iterative image reconstruction algorithms are based on some form of optimization, such as minimization of a data-fidelity term plus an image regularizing penalty term.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
