Investigating the Rosetta/RTOF observations of comet 67P/Churyumov-Gerasimenko using a comet nucleus model: influence of dust mantle and trapped CO [PDF]
, 2020 Context. Cometary outgassing is induced by the sublimation of ices and the ejection of dust originating from the nucleus. Therefore measuring the composition and dynamics of the cometary gas provides information concerning the interior composition of the

Advanced Materials, EarlyView.Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

, 2021 This thesis presents a study of the gas dynamics of cometary nuclei with a focus on the target of the Rosetta mission, comet 67P/Churyumov-Gerasimenko. We therefore apply the 3D Direct Simulation Monte Carlo (DSMC) method to different distributions of ...

Automated Dynamic Flow Experimentation for Rapid Kinetic Fitting of Transition Metal Catalysis
Angewandte Chemie, EarlyView.We have developed an automated dynamic flow experimentation platform to automatically fit and identify the most accurate kinetic model from a generated set of candidates. Three transition metal‐catalyzed transformations were performed using this workflow.

Realistic Models for the Comet Dynamical Environment [PDF]
AIAA/AAS Astrodynamics Specialist Conference and Exhibit, 2006 An outgassing jet model is presented in support of spacecraft navigation for future missions to comets. The outgassing jet is modelled as an emission cone while the comet is modelled as a uniform density triaxial ellipsoid. The comet’s motion about the Sun is included in the model.

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities
Advanced Science, EarlyView.ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

The Astronomical Journal, 2023 Short-period comet 108P/Ciffreo is known for its peculiar double morphology, in which the nucleus is accompanied by a comoving, detached, diffuse “blob.” We report new observations of 108P/Ciffreo taken with the Hubble Space Telescope and the Nordic ...

Advanced Science, EarlyView.This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

Recurrent Cometary Activity Discovered on Quasi-Hilda Jupiter Family Comet 362P/(457175) 2008 GO98
The Astrophysical Journal LettersWe report the discovery of recurrent activity on quasi-Hilda comet (QHC) 362P/(457175) 2008 GO _98 . The first activity epoch was discovered during the perihelion passage of 362P in 2016, so we were motivated to observe it for recurrent cometary activity
