Sampling Tree Fragments from Forests [PDF]
Computational Linguistics, 2014 We study the problem of sampling trees from forests, in the setting where probabilities for each tree may be a function of arbitrarily large tree fragments. This setting extends recent work for sampling to learn Tree Substitution Grammars to the case where the tree structure (TSG derived tree) is not fixed.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Brazil’s fragmented forests [PDF]
Current Biology, 2017 Summary One of the largest and longest-running biological experiments shows how habitat fragmentation damages the Amazonian forests. Meanwhile, recent political troubles in Brazil may open the path for more unbridled deforestation. Michael Gross reports.

Conservation: Forest Fragments, Facts, and Fallacies [PDF]
Current Biology, 2013 Most of the world's remaining habitats are split into small fragments that lose species quickly. Knowledge of this fact can guide practical actions to prevent extinctions.

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

Molecular Oncology, EarlyView.Interferon type 1 (IFN‐1) production and signaling is associated with the acquisition of therapy resistance, following chronic DNA damage, via Interferon‐related DNA damage resistance signature (IRDS) gene expression. An alternative, DNA damage‐independent role of sustained IFN‐1 mediated resistance was identified and characterized by the emergence of ...

Forest fragmentation and selective logging affect the seed survival and recruitment of a relictual conifer [PDF]
, 2018 Defaunation, invasive species and forest fragmentation are considered to be the major drivers for the disruption of key ecological processes, particularly those related to plant animal-interactions such as seed dispersal and predation.

Forest fragmentation assessment using field-based sampling data from forest inventories [Elektronisk resurs] [PDF]
, 2021 Forest fragmentation has a relevant impact on biodiversity. An interesting alternative to estimate these indices is to use sampling data. This study aims to estimate aggregation index (AI) and the degree of clumping of forested landscape based on AI. The

Effects of Urban Expansion on Forest Loss and Fragmentation in Six Megaregions, China
Remote Sensing, 2017 Urban expansion has significant effects on forest loss and fragmentation. Previous studies mostly focused on how the amount of developed land affected forest loss and fragmentation, but neglected the impacts of its spatial pattern.

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
FEBS Open Bio, EarlyView.HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral
