Planets Around Solar Twins/Analogs (PASTA). I. High-precision Stellar Chemical Abundances for 17 Planet-hosting Stars and the Condensation Temperature Trend

The Astrophysical Journal
The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 solar-like stars hosting ...

High-precision analysis of binary stars with planets. I. Searching for condensation temperature trends in the HD 106515 system

, 2019
We explore the probable chemical signature of planet formation in the remarkable binary system HD 106515. The A star hosts a massive long-period planet with 9 MJup detected by radial velocity.

Survival of Terrestrial Planets in the Presence of Giant Planet Migration [PDF]

, 2003
The presence of ``Hot Jupiters'', Jovian mass planets with very short orbital periods orbiting nearby main sequence stars, has been proposed to be primarily due to the orbital migration of planets formed in orbits initially much further from the parent star.

Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

Advanced Materials Technologies, EarlyView.
Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies are employed to stabilize SnO2 upon cycling i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating.

The multifactorial aquaculture‐related COVID‐19 shock in Benin, West Africa: A socio‐economic perspective of mitigating the disruptive impacts on the small‐scale and subsistence producers

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 507-521, December 2022., 2022
Graphical Abstract This study deals with a timely topic, COVID‐19, whose impacts on aquaculture have never been quantified in Benin. Direct discussions were held with aquaculture producers to understand how they are feeling the impact of the pandemic on their business.

Modeling Planetary System Formation with N-Body Simulations: Role of Gas Disk and Statistics Comparing to Observations

, 2011
During the late stage of planet formation when Mars-size cores appear, interactions among planetary cores can excite their orbital eccentricities, speed their merges and thus sculpture the final architecture of planet systems.

A Bistable Assistive Device for Wireless Control of a Dysfunctional Bladder Under Minimal Stress

Advanced Materials Technologies, EarlyView.
This paper presents a wireless system designed to restore bladder function in patients with an underactive bladder (UAB). The system features a multilayered structure, combining a pre‐shaped restoration layer with a spring‐based actuator. The system delivers 95–100% voiding efficiency within a 10‐s activation while ensuring minimal stress on the ...

Yield estimation of summer maize based on multi‐source remote‐sensing data

Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022
Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution
