Taxonomic revision of Sobralia section Racemosae Brieger (Sobralieae, Orchidaceae)

Frontiers in Ecology and Evolution, 2023
Sobralia Ruiz & Pav. is a large and morphologically diverse neotropical orchid genus. It can be divided into four sections and some informal groups of species based mainly on the inflorescence architecture.

What a MESS: Multi-Domain Evaluation of Zero-Shot Semantic Segmentation [PDF]

arXiv, 2023
While semantic segmentation has seen tremendous improvements in the past, there are still significant labeling efforts necessary and the problem of limited generalization to classes that have not been present during training. To address this problem, zero-shot semantic segmentation makes use of large self-supervised vision-language models, allowing ...

Crosstalk between gut microbiota and tumor: tumors could cause gut dysbiosis and metabolic imbalance

Molecular Oncology, EarlyView.
In this research, we analyzed the relationship between gut microbiota and tumor. We discovered that both subcutaneous and metastatic tumors would alter the composition and metabolic function of gut microbiota. Meanwhile, fecal microbiota transplantation also indicated the anti‐tumor role of the gut microbiota, revealing the crosstalk between tumor and ...

Evolution of morphological traits of Dendrobium sensu lato (Orchidaceae)—an attempt to resolve phylogenetic relationships in nominal and morphologically convergent sections

BMC Plant Biology
Background Dendrobium is a large genus within the Orchidaceae family, containing over 1,600 species. Most are sympodial epiphytes. These species are distributed throughout southern, eastern, and southeastern Asia, the Pacific Islands, Australia, New ...

Respiratory complex I‐mediated NAD+ regeneration regulates cancer cell proliferation through the transcriptional and translational control of p21Cip1 expression by SIRT3 and SIRT7

Molecular Oncology, EarlyView.
NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional

CoRel: Seed-Guided Topical Taxonomy Construction by Concept Learning and Relation Transferring [PDF]

, 2020
Taxonomy is not only a fundamental form of knowledge representation, but also crucial to vast knowledge-rich applications, such as question answering and web search. Most existing taxonomy construction methods extract hypernym-hyponym entity pairs to organize a "universal" taxonomy.

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.

The application of haplotypes instead of species-level ranks modifies the interpretation of ecological preferences in lichen symbiont interactions in Parmelia

Scientific Reports
The analysis of the interaction between main bionts (mycobiont and photobiont) in the lichen symbiosis delivers substantial information about their preferences in the selection of symbiotic partners, and their ecological preferences.

Comparison of rodent community between natural and modified habitats in Kafta-Sheraro National Park and its adjoining villages, Ethiopia: implication for conservation

Journal of Basic and Applied Zoology, 2019
Background Distribution and diversity of rodents vary across habitats due to different environmental factors. An ecological comparative study on diversity and abundance of rodents was conducted in Kafta-Sheraro National Park and its nearby villages from ...

RaTE: a Reproducible automatic Taxonomy Evaluation by Filling the Gap [PDF]

arXiv, 2023
Taxonomies are an essential knowledge representation, yet most studies on automatic taxonomy construction (ATC) resort to manual evaluation to score proposed algorithms. We argue that automatic taxonomy evaluation (ATE) is just as important as taxonomy construction.
