A Heterothermic Kinetic Model of Hydrogen Absorption in Metals with Subsurface Transport

open access: yesMetals, 2019
A versatile numerical model for hydrogen absorption into metals was developed. Our model addresses the kinetics of surface adsorption, subsurface transport (which plays an important role for metals with active surfaces), and bulk diffusion processes ...

Epidemiology of Cancer‐Associated Venous Thromboembolism Across the United States

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Prior epidemiological studies on cancer‐associated venous thromboembolism (VTE) were limited by homogenous patient populations. We leverage Cosmos, a collaborative dataset of Epic electronic health record systems, to conduct an updated evaluation of cancer‐associated VTE in the United States (US).

Myelitis‐Predominant Aggressive Phenotype: Unveiling Unique Patterns of Late‐Onset Neuromyelitis Optica Spectrum Disorders

open access: yesAnnals of Neurology, EarlyView.
Objective The objective of this study was to compare clinical features and prognosis of late‐onset neuromyelitis optica spectrum disorder (LO‐NMOSD, onset age ≥60 years) with adult‐onset NMOSD (AO‐NMOSD, onset age 18–59 years), and to provide insights for individualized management in elderly patients.

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

open access: yesAnnals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren

open access: yesAngewandte Chemie, EarlyView.
Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

Modulated photonic-crystal surface-emitting laser with elliptical lattice points for two-dimensional coupling enhancement

open access: yesAIP Advances, 2019
Modulated photonic-crystal surface-emitting lasers (M-PCSELs) are new semiconductor lasers that can emit a laser beam in arbitrary directions. Therefore, they can be regarded as a next-generation light source for light detection and ranging.

Dibenzazepine Bridged Network Polymeric Phthalocyanines as Degradable Heterogeneous Photocatalysts

open access: yesAngewandte Chemie International Edition, EarlyView.
Dibenzazepine photodynamic bridge has been introduced to zinc and cobalt networks phthalocyanines (NP‐Pcs) to obtain degradable heterogeneous photocatalysts. For the first time, light irradiation plays a key role in “design, use and degradation” of NP‐Pcs.
