Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Inundation frequency correction method for mapping multi-temporal tidal flat topography integrating Sentinel-1 and ICESat-2 data

open access: yesGeo-spatial Information Science
Remote sensing monitoring of tidal flat topographic changes is essential for analyzing the tidal flat evolution and coastal stability. However, the inter-annual inconsistency of inundation frequency limited the capacity of multi-temporal tidal flat ...

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

In-situ tests on pore-water pressure response and consolidation mechanism of surface sediments in tidal flat of Yellow River Delta under tide and wave loading

open access: yesYantu gongcheng xuebao
In order to study the pore pressure response and consolidation mechanism of the surface sediments in the tidal flat of the Yellow River Delta under the action of wave and tide loading, the fluid sediments imitating the rapidly deposited seabed silty ...

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

open access: yesThe Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Strong field gravitational lensing by a charged Galileon black hole

open access: yes, 2016
Strong field gravitational lensings are dramatically disparate from those in the weak field by representing relativistic images due to light winds one to infinity loops around a lens before escaping.

Smaller Lateral‐to‐Medial Tibial Plateau Ratios Are Strongly Correlative With Anterior Cruciate Ligament Tears and Reconstruction Failures

open access: yesArthroscopy, EarlyView.
Purpose To compare the anterior–posterior distance ratio of the lateral‐to‐medial tibial plateau (LTP/MTP) among 3 patient groups: those with intact anterior cruciate ligaments (ACLi), primary ACL tears (ACLp), and failed ACL reconstructions (ACLf).

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Draco, a flawless dwarf galaxy

open access: yes, 2006
The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass to light ratio and compact size, holds many clues to the nature of the enigmatic dark matter.

Quantifying the Impact of Relativistic Precession on Tidal Disruption Event Light Curves

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The tidal field of a black hole can turn a star into a gas stream whose orbit can precess, especially if the a black hole is rapidly spinning. In this work, we investigate the impact of precession on the light curves of tidal disruption events (TDE).
