High‐Sugar Diet and Intestinal Diseases: A Shared Microbiota–Barrier–Immunity–Metabolism Axis in Inflammatory Bowel Disease, Food Allergy, and Colorectal Cancer

iNew Medicine, EarlyView.
ABSTRACT The global incidence of intestinal diseases—including food allergy, inflammatory bowel disease (IBD), and colorectal cancer (CRC)—continues to escalate in parallel with the expansion of the “Western diet,” within which the high‐sugar diet (HSD) has emerged as a pivotal yet under‐recognized dietary driver.

Hydrofluorocarbons (HFCs) [PDF]

, 2019
The Montreal Protocol is an international agreement designed to heal the ozone layer. It outlines schedules for the phase-out of ozone-depleting substances (ODSs) such as chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), chlorinated solvents,

Radiative forcing of climate by hydrochlorofluorocarbons and hydrofluorocarbons

, 1995
We measure infrared absorption spectra of 18 hydrochlorofluorocarbons and hydrofluorocarbons, seven of which do not yet appear in the literature. The spectra are used in a narrowband model of the terrestrial infrared radiation to calculate radiative ...

Large Datasets for the Euro Area and Its Member Countries and the Dynamic Effects of the Common Monetary Policy

Journal of Applied Econometrics, EarlyView.
ABSTRACT We introduce EA‐MD‐QD, a new publicly available dataset comprising 1136 macroeconomic time series for the euro area (EA) and its ten largest member countries observed at monthly or quarterly frequency. Since January 2024, EA‐MD‐QD has been updated monthly and continuously revised, providing a valuable resource for policy analysis in the EA ...

Solubilities of hydrofluorocarbons in ionic liquids: experimental and modelling study

, 2014
In this work, experimental data on the gas solubility of hydrofluorocarbons (CHF3, CH2F2 and CH3F) in four room-temperature ionic liquids (RTILs) were determined within the temperature range 288 K to 308 K and at atmospheric pressure. The RTILs used were

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...
