Occurrence data on brominated phenols and their derivatives provided to EFSA
<p><span>The file contains the raw occurrence dataset on brominated phenols and their derivatives in food as extracted from EFSA DWH on 1 of December 2022 and presented in the EFSA opinion on the update of the risk assessment of brominated phenols and their derivatives in food. This dataset is compliant with EFSA SSD2 data model and contains two additional columns documenting issues identified in the cleaning process (column: issue) and the outcome of the action taken (column: outcome) to address the issue (e.g. delete record or update values in specific fields). The link to the catalogues of controlled terminologies for the updated textual description of fields values can be found under "Related works, supplemented by”.</span></p>
A Submesoscale Eddy Identification Dataset Derived from GOCI I Chlorophyll–a Data based on Deep Learning
<p>This is an observational dataset on submesoscale eddies, which obtains from high–resolution chlorophyll–a distribution images from GOCI I. We employed a combination of digital image processing, filtering, YOLOv7–X, and small object detection techniques, along with specific chlorophyll image enhancement processing, to extract information on submesoscale eddies, including their time, polarity, geographical coordinates of the eddy center, eddy radius, coordinates of the upper left and lower right corners of the prediction box, area of the eddy's inner ellipse, and confidence score, which covers eight daily periods between 00:00 and 08:00 (UTC) from April 1, 2011, to March 31, 2021. We identified a total of 19,136 anticyclonic eddies and 93,897 cyclonic eddies at a confidence threshold of 0.2. The mean radius of anticyclonic eddies is 24.44 km (range 2.5 km to 44.25 km), while that of cyclonic eddies is 12.34 km (range 1.75 km to 44 km). The unprecedented hourly resolution dataset on submesoscale eddies provides information on their distribution, morphology, and energy dissipation, making it a significant contribution to understanding marine environments and ecosystems, as well as improving climate model predictions.

Dinitrogen Reduction and Functionalization by a Siloxide Supported Thulium-Potassium Complex for the Formation of Ammonia or Hydrazine Derivatives
<p>The dinitrogen (N2) chemistry of lanthanides remainsless developed compared to the d-block metals and lanthanide-promoted N2 functionalization chemistry in well-defined lanthanidecomplexes remains elusive. Here we report the synthesis andcharacterization (SQUID, EPR, DFT, X-Ray) of the siloxidesupported heterobimetallic (Tm/K) complexes[{KTm(OSi(OtBu)3)3}2(μ-η2:η2-N2)] (1) and [K3{Tm(OSi(OtBu)3)3}2(μ-η2:η2-N2)] (2). Complex 2 provides a rare example of a metalcomplex of the triply reduced N23- radical. The structure of 2 differsfrom the few previously reported N23- complexes as it presents twoTm and three K cations binding the N23- radical, facilitating N2functionalization. Notably, the K3Tm2-bound N23- moiety reacts withexcess H+ to form NH4Cl in 18% yield, and with MeOTf at roomtemperature to yield the dimethyl hydrazido complex[K2{Tm(OSi(OtBu)3)3}2(μ-(CH3)NN(CH3))] (3). Protonolysis of 3yields MeHN-NMeH·2HCl in 18 % yield.</p>

Conformance Assessment of Architectural Design Decisions on API Endpoint Designs Derived from Domain Models: Dataset and Code
<p>This is the dataset and related code artifact for the article "Conformance Assessment of Architectural Design Decisions on API Endpoint Designs Derived from Domain Models".</p> <p><strong>Abstract of the article:</strong></p> <p>Domain-driven design (DDD) is commonly used, especially in enterprise systems, to design microservices. A crucial aspects of microservice design is API design, which includes the design of API endpoints. In particular, we studied link mapping, API operation design, and resource segregation as API endpoint design issues that are linked to domain model design. Based on Architectural Design Decisions (ADD) studied in a prior empirical study on the interrelation of DDD and APIs, we suggest a new approach for the automated assessment of conformance to ADD options. This approach aims to support the continuous analysis of API endpoint designs. The approach suggests automated detectors to detect ADD options selected in a given API endpoint design, as well as an assessment scoring scheme based on our empirical results. For evaluation of our results, we first manually created a ground truth for 12 cases in a multi-case study, and then compared the results of our automated detectors to the ground truth for each of those cases.</p>
Functional beta diversity of New Zealand fishes: characterising morphological turnover along depth and latitude gradients, with derivation of functional bioregions
<p>Changes in the functional structures of communities are rarely examined along multiple large-scale environmental gradients. Here, we describe patterns in functional beta diversity for New Zealand marine fishes <i>vs</i> depth and latitude, including broad-scale delineation of functional bioregions. We derived eight functional traits related to food acquisition and locomotion and calculated complementary indices of functional beta diversity for 144 species of marine ray-finned fishes occurring along large-scale depth (50 - 1200 m) and latitudinal gradients (29° - 51° S) in the New Zealand Exclusive Economic Zone. We focused on a suite of morphological traits calculated directly from <i>in situ</i> Baited Remote Underwater Stereo-Video (stereo-BRUV) footage and museum specimens. We found that functional changes were primarily structured by depth followed by latitude, and that latitudinal functional turnover decreased with increasing depth. Functional turnover among cells increased with increasing depth distance, but this relationship plateaued for greater depth distances (> 750 m). In contrast, functional turnover did not change significantly with increasing latitudinal distance at 700 - 1200 m depths. Shallow functional bioregions (50 - 100 m) were distinct at different latitudes, whereas deeper bioregions extended across broad latitudinal ranges. Fishes in shallow depths had a body shape conducive to efficient propulsion, while fishes in deeper depths were more elongated, enabling slow, energy-efficient locomotion, and had large eyes to enhance vision. Environmental filtering may be a primary driver of broad-scale patterns of functional beta diversity in the deep sea. Greater environmental homogeneity may lead to greater functional homogeneity across latitudinal gradients at deeper depths (700 - 1200 m). We suggest that communities living at depth may follow a 'functional village hypothesis', whereby similar key functional niches in fish communities may be maintained over large spatial scales.</p>

Advanced Glycation End-products are Retained in Decellularized Muscle Matrix Derived from Aged Skeletal Muscle
<p>Advanced glycation end-products (AGEs) accrue on skeletal muscle collagen in old age, stiffening the matrix and increasing inflammation. Whether decellularized biomaterials derived from aged muscle would suffer from increased AGE cross-links is unknown. We hypothesized that DMM from old muscle would have increased collagen, collagen cross-linking, stiffness, and AGEs. We isolated, decellularized, and characterized gastrocnemii of 1-month, 2-month, and 20-month old C57BlJ6 mice to determine age-dependent changes to collagen in muscle and decellularized muscle matrix (DMM). Total hydroxyproline and soluble hydroxyproline after proteinase K digestion were measured to assay collagen levels and cross-linking, respectively. Muscle fiber and DMM stiffness was determined using atomic force microscopy (AFM). AGE ELISAs were used to test AGE levels, and the effect of AGE cross-link breaker ALT-711 on DMM was tested. We determined age-dependent increases in collagen amount, cross-linking, and general stiffness are retained on DMM. DMM from old muscle was stiffer compared to younger groups according to shifts in AFM modulus distribution. We measured an increase in AGE-specific cross-links with old age in whole muscle and observed that these changes are countered in DMM by AGE cross-link breaker ALT-711. Future study investigating and countering the biological effects of old age on DMM is warranted.</p>
