Is the Hubble Crisis Connected with the Extinction of Dinosaurs?

Universe, 2022
It has recently been suggested that a gravitational transition of the effective Newton’s constant Geff by about 10%, 50–150 Myrs ago could lead to the resolution of both the Hubble crisis and the growth tension of the standard ΛCDM model.

Use of ultrasonography in assessing peri‐implant osseous defects: An in vitro study

Journal of Periodontology, EarlyView.
Abstract Background The purpose of this study is to investigate the feasibility and diagnostic accuracy of ultrasonography in peri‐implant defect identification and evaluation, and to compare ultrasonography (USG) with cone‐beam computed tomography (CBCT) in defect identification and evaluation in an in vitro model.

Watching a Comet Turn On: High Spectral Resolving Power Observations of Comet C/2017 K2 (PanSTARRS)

The Planetary Science Journal
We report high spectral resolving power optical observations of comet C/2017 K2 (PanSTARRS) as it approached the Sun. This comet was discovered when it was 16 au from the Sun. At discovery, the comet had a large and relatively bright coma.

Oort Cloud Comets: Perturbations Due to the Passage of Gliese 710

Universe
The outermost region of the Solar System is called the Oort cloud, which is the Solar System’s reservoir of long-period comets that extends to distances up to 200,000 au from the Sun.

Influence of the growing area on cone yield and alpha and beta acid content in Cascade hops: An Italian case study

JSFA reports, EarlyView.
Abstract Background Territorial food production is a well‐known quality trait, which is attracting new customer preferences for different agricultural products. In this context, many microbreweries and agricultural breweries started to cultivate their own small hopyard to exploit the so‐called “terroir” effect.

Hop production in a low‐trellis espalier system in the subtropical environment

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Hop cultivation (Humulus lupulus L.) is expanding into new regions, particularly under subtropical conditions. Traditionally, hop plants are trained using high‐trellis systems; however, a low‐trellis espalier structure may reduce establishment costs, facilitate phytosanitary management, and improve harvest uniformity.

Nail Disorders in Systemic Conditions

JEADV Clinical Practice, EarlyView.
ABSTRACT Nail findings in children can be indicative of an underlying systemic disease. Many of these findings are seen in multiple entities and are not specific to one disease. The importance of specifically examining for these nail changes cannot be overstated.

Iterative Navigator‐Based Retrospective Motion Correction for Multi‐Shot Brain MR Elastography and Evaluation of Single‐Shot Post‐Reconstruction Correction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Brain MR elastography (MRE) is uniquely sensitive to subject motion, as even small phase deviations can produce large errors in the mechanical properties estimated. Existing motion correction strategies have not been validated for MRE and are often incompatible with complex multi‐shot or joint temporal reconstructions.

Early CN Outgassing and Production Rates of C/2024 E1 (Wierzchos) at 4 au

The Planetary Science Journal
The study of cometary activity at large heliocentric distances provides insights into the volatile release processes in the outer solar system. Early models predicted cometary activity was driven primarily by sublimation of water and therefore would ...
