Update of the list of QPS-recommended biological agents intentionally added to food or feed as notified to EFSA 10: Suitability of taxonomic units notified to EFSA until March 2019. [PDF]

EFSA J, 2019
Abstract The qualified presumption of safety (QPS) procedure was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's Scientific Panels. The taxonomic identity, body of knowledge, safety concerns and antimicrobial resistance were assessed.

Nonlinear Internal Tides in a Realistically Forced Global Ocean Simulation

Journal of Geophysical Research: Oceans, Volume 128, Issue 12, December 2023., 2023
Abstract The decay of the low‐mode internal tide due to the superharmonic energy cascade is investigated in a realistically forced global Hybrid Coordinate Ocean Model simulation with 1/25° (4 km) horizontal grid spacing. Time‐mean and depth‐integrated supertidal kinetic energy is found to be largest near low‐latitude internal tide generation sites ...

Boundary Upwelling of Antarctic Bottom Water by Topographic Turbulence

AGU Advances, Volume 4, Issue 5, October 2023., 2023
Abstract The lower cell of the meridional overturning circulation (MOC) is sourced by dense Antarctic Bottom Waters (AABWs), which form and sink around Antarctica and subsequently fill the abyssal ocean. For the MOC to “overturn,” these dense waters must upwell via mixing with lighter waters above.

Using unoccupied aerial vehicles to map and monitor changes in emergent kelp canopy after an ecological regime shift

Remote Sensing in Ecology and Conservation, Volume 9, Issue 1, Page 62-75, February 2023., 2023
Despite their ecological and economic importance, kelp forest abundance has declined in many regions around the world including the North Coast of California. Given the significant loss of kelp in this region, management intervention is likely necessary and remotely sensed data on kelp dynamics can help inform strategic restoration projects.

Identification and Pathogenicity of Emerging Fish Pathogen Acinetobacter johnsonii from a Disease Outbreak in Rainbow Trout (Oncorhynchus mykiss)

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
In November 2017, a group of farmed rainbow trout (Oncorhynchus mykiss) died in Yunnan Province, China, likely due to infection. These rainbow trout exhibited slow movement, no feeding, dark body color, exophthalmia, and occasional ulcers on the body surface.

Global Barotropic Tide Modeling Using Inline Self‐Attraction and Loading in MPAS‐Ocean

Journal of Advances in Modeling Earth Systems, Volume 14, Issue 11, November 2022., 2022
Abstract We examine ocean tides in the barotropic version of the Model for Prediction Across Scales (MPAS‐Ocean), the ocean component of the Department of Energy Earth system model. We focus on four factors that affect tidal accuracy: self‐attraction and loading (SAL), model resolution, details of the underlying bathymetry, and parameterized ...

The Impact of Representations of Realistic Topography on Parameterized Oceanic Lee Wave Energy Flux

Journal of Geophysical Research: Oceans, Volume 127, Issue 10, October 2022., 2022
Abstract Oceanic lee waves are generated when quasi‐steady flows interact with rough topography at the bottom of the ocean, providing an important sink of energy and momentum from the mean flow and a source of turbulent kinetic energy. Linear theory with a spectral representation of topography is typically used to inform parameterizations of lee wave ...

Modification of Internal Wave Generation and Energy Conversion in the Nearshore Due To Tide‐Tide and Tide‐Wind Interactions

Journal of Geophysical Research: Oceans, Volume 127, Issue 4, April 2022., 2022
Abstract Internal wave generation due to semi‐diurnal tides (M2) through the acceleration of barotropic tidal flow over sloped topography has received considerable attention over the past several decades. However, the contribution of other tidal constituents and their interactions with M2 have not been as extensively evaluated.

Tricyclic graphs with maximum Merrifield–Simmons index [PDF]

, 2010
It is well known that the graph invariant, ‘the Merrifield–Simmons index’ is important one in structural chemistry. The connected acyclic graphs with maximal and minimal Merrifield–Simmons indices are determined by Prodinger and Tichy [H. Prodinger, R.F.

Extremal Hosoya index and Merrifield–Simmons index of hexagonal spiders [PDF]

, 2008
For any graph G, let m(G) and i(G) be the numbers of matchings (i.e., the Hosoya index) and the number of independent sets (i.e., the Merrifield–Simmons index) of G, respectively.
