COSINE (Cometary Object Study Investigating Their Nature and Evolution). I. Project Overview and General Characteristics of Detected Comets

open access: yesThe Astrophysical Journal Supplement Series
We present the first results from the Cometary Object Study Investigating their Nature and Evolution (COSINE) project, based on a uniformly processed data set of 484 comets observed over the full 15 yr duration of the Wide-field Infrared Survey Explorer (

Identification of Novel Interacting Proteins of FUZ and GPR161

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Protein–protein interactions are central to the dynamic regulation of signaling pathways and provide critical insight into the cellular mechanisms underlying human disease. Our previous study demonstrated biochemical and genetic interactions between FUZ and GPR161 in sonic hedgehog signaling during spinal neural tube development. In this study,

Comets [PDF]

open access: yes, 2006
Spectroscopy of comets, in the X-ray and far-ultraviolet from space, and in the near infrared and millimeter from the ground, have revealed a wealth of new information, particularly about the molecular constituents that make up the volatile fraction of ...

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

open access: yesJournal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by

A Search of Reactivated Comets [PDF]

open access: yes, 2017
Dormant or near-dormant short-period comets can unexpectedly regain the ability to eject dust. In many known cases, the resurrection is short-lived and lasts less than one orbit.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Comets: Data, problems, and objectives [PDF]

open access: yes, 1977
A highly abridged review of new relevant results from the observations of Comet Kohoutek is followed by an outline summary of our basic knowledge concerning comets, both subjects being confined to data related to the nature and origin of comets rather ...
