Sculpting of Exoplanetary Systems Driven by a Misaligned Disk and Stellar Oblateness: Origin of Perpendicular Orbits in HD 3167

open access: yesThe Astrophysical Journal Letters
A significant proportion of exoplanets have been detected with highly tilted or even polar orbits relative to their host stars’ equatorial planes. These unusual orbital configurations are often linked to postdisk secular interactions among multiple ...

From Agro‐Industrial Waste to Functional Packaging Using Antimicrobial and Mechanically Reinforced Starch Foams With Melon Seed and Rosemary

open access: yesJournal of Applied Polymer Science, EarlyView.
Agro‐industrial waste was upcycled into biodegradable starch foams reinforced with melon seed and rosemary flours, yielding sustainable food packaging with enhanced mechanical performance, selective antimicrobial activity, and rapid biodegradation. ABSTRACT The demand for sustainable alternatives to petroleum‐based packaging has promoted starch‐based ...

Bifurcated Evolutionary Pathways in Multiplanet Systems Driven by Misaligned Protoplanetary Disks

open access: yesThe Astrophysical Journal Letters
Stellar obliquities, or spin–orbit angles, prevalent in exoplanet systems, can impose important constraints on their formation and evolution histories.

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

open access: yesAdvanced Physics Research, EarlyView.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Quantifying the Impact of the Dust Torque on the Migration of Low-mass Planets. II. The Role of Pebble Accretion in Planet Growth within a Global Planet Formation Model

open access: yesThe Astrophysical Journal
Although dust constitutes only about 1% of the mass in a protoplanetary disk, recent studies reveal its substantial impact on the torques experienced by low- and intermediate-mass planetary cores.

Low-Energy Cosmic Rays and Associated MeV Gamma-Ray Emissions in the Protoplanetary System

open access: yesUniverse
Low-energy cosmic rays (LECRs) play a crucial role in the formation of planetary systems, and detecting and reconstructing the properties of early LECRs is essential for understanding the mechanisms of planetary system formation.

Generating a Jump Distance Based Synthetic Disk Access Pattern [PDF]

open access: yes, 2006
As part of our on-going research into improving the quality of synthetic, block-level I/O workloads, we have developed an algorithm that generates a synthetic (i.e., random) disk access pattern based on both (1) a given distribution of sectors accessed ...

Clade‐wide morphological and functional variation of the sauropsid columella

open access: yesThe Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

ALMA Reveals an Eccentricity Gradient in the Fomalhaut Debris Disk

open access: yesThe Astrophysical Journal
We present evidence of a negative eccentricity gradient in the debris disk of the nearby A-type main-sequence star, Fomalhaut. Fitting to the high-resolution, archival ALMA 1.32 mm continuum data for Fomalhaut (with a synthesized angular resolution of 0 $
