Pharmacological Inhibition of APT2 by Solasonine Promotes Ferroptosis Through Palmitoylation Modulation in Gallbladder Cancer

open access: yesPhytotherapy Research, EarlyView.
Schematic illustration of SS‐induced ferroptosis through targeting APT2‐mediated STAT3 palmitoylation in GBC cells. ABSTRACT Gallbladder cancer (GBC), the most prevalent and lethal biliary tract malignancy, lacks effective therapeutic strategies. Solasonine (SS), a bioactive steroidal alkaloid derived from Solanum nigrum L, exhibits antitumor activity ...

Thermodynamic and microphysical properties of summertime marine fog observed from Sable Island

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Atmospheric profiling and near‐surface fog and visibility measurements revealed synoptic‐scale forcing as the dominant factor in fog formation over Sable Island, with deep fog layers under low‐pressure systems and shallow fog layers under high‐pressure systems.

Microphysical chemistry of fog–aerosol interactions over the northwest Atlantic Ocean during Fatima 2022

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Fifteen size‐resolved aerosol samples collected during marine fog, with adjacent ambient observations, show that coarse sea salt aerosol is rapidly grown and lost in the northwest North Atlantic Ocean except when subject to extreme winds. The persistence of fog in the absence of sea salt is determined by available fine‐mode aerosol, where greater ...

End‐to‐End Portfolio Optimization with Hybrid Quantum Annealing

open access: yesAdvanced Quantum Technologies, EarlyView.
This works presents a hybrid quantum‐classical framework for portfolio optimization that combines quantum assisted asset selection and rebalancing with classical weight allocation. The approach processes real market data, embeds it into Quadratic Unconstrained Binary Optimization formulations, and evaluates performance within a unified workflow ...

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

“There Are Places Full of Beauty”: Desettling High School Students' Scientific Writing

open access: yesScience Education, EarlyView.
ABSTRACT This study contributes to desettling and expanding expectations about the forms of scientific language that belong in students' scientific writing. The primary empirical focus is the analysis of 52 high school student abstracts articulating community‐based investigations, submitted as part of their participation in a student conference in a ...
