Atomistic assessment of interfacial interaction potential in tungsten twist grain boundaries

The present study focuses on the computation of interfacial excess potential for the cohesive zones through which a brittle crack propagates in tungsten (W) twist grain boundaries (TGBs). Additionally, the influence of phosphorus (P) impurities is investigated. To this end, we have performed classical atomistic modeling of several ⟨110⟩ TGBs in their pristine and P-impurity segregated states. The

Evaluation of alternative prognostic thresholds for SP142 and 22C3 immunohistochemical PD-L1 expression in triple-negative breast cancer : results from a population-based cohort

Background: Immune checkpoint inhibitors are now a part of the treatment arsenal for triple-negative breast cancer (TNBC) but refinement of PD-L1 as a prognostic and predictive biomarker is a clinical priority. We aimed to evaluate the relevance of novel PD-L1 immunohistochemical (IHC) thresholds in TNBC with regard to PD-L1 gene expression, prognostic value, tumor infiltrating lymphocytes (TILs),

Analysis of correlations between health-related quality of life and clinical measures after arthroscopic lysis and lavage of the temporomandibular joint

How well patient perceived outcome reflects clinical measurements after arthroscopic lysis and lavage of the temporomandibular joint (TMJ) is not fully understood.The purpose of this study was to detect any correlation between patient reported outcome measures (PROM) and clinical follow-up measurements.Patients with internal derangement of the TMJ treated with arthroscopic lysis and lavage 2014–20

The Authority of Translators : Vendors, Manufacturers, and Materiality in the Transfer of Barlaam and Josaphat along the Silk Road

Texts–and the stories and teachings they contained–travelled far along the Silk Road in the hands of merchants, missionaries, monastic communities and many more. The intricate itineraries and the many languages and scripts used on the way have received much attention, and we can therefore follow some of the stages and versions that stories like the Barlaam and Josaphat (as it was known in the West

Divergent mutational processes distinguish hypoxic and normoxic tumours

Many primary tumours have low levels of molecular oxygen (hypoxia), and hypoxic tumours respond poorly to therapy. Pan-cancer molecular hallmarks of tumour hypoxia remain poorly understood, with limited comprehension of its associations with specific mutational processes, non-coding driver genes and evolutionary features. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG)

High-coverage whole-genome analysis of 1220 cancers reveals hundreds of genes deregulated by rearrangement-mediated cis-regulatory alterations

The impact of somatic structural variants (SVs) on gene expression in cancer is largely unknown. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole-genome sequencing data and RNA sequencing from a common set of 1220 cancer cases, we report hundreds of genes for which the presence within 100 kb of an SV breakpoint associates with altered e

Reconstructing evolutionary trajectories of mutation signature activities in cancer using TrackSig

The type and genomic context of cancer mutations depend on their causes. These causes have been characterized using signatures that represent mutation types that co-occur in the same tumours. However, it remains unclear how mutation processes change during cancer evolution due to the lack of reliable methods to reconstruct evolutionary trajectories of mutational signature activity. Here, as part o

Inferring structural variant cancer cell fraction

We present SVclone, a computational method for inferring the cancer cell fraction of structural variant (SV) breakpoints from whole-genome sequencing data. SVclone accurately determines the variant allele frequencies of both SV breakends, then simultaneously estimates the cancer cell fraction and SV copy number. We assess performance using in silico mixtures of real samples, at known proportions,

Integrative pathway enrichment analysis of multivariate omics data

Multi-omics datasets represent distinct aspects of the central dogma of molecular biology. Such high-dimensional molecular profiles pose challenges to data interpretation and hypothesis generation. ActivePathways is an integrative method that discovers significantly enriched pathways across multiple datasets using statistical data fusion, rationalizes contributing evidence and highlights associate

A deep learning system accurately classifies primary and metastatic cancers using passenger mutation patterns

In cancer, the primary tumour's organ of origin and histopathology are the strongest determinants of its clinical behaviour, but in 3% of cases a patient presents with a metastatic tumour and no obvious primary. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, we train a deep learning classifier to predict cancer type based on patterns of somatic passenger mu

Pathway and network analysis of more than 2500 whole cancer genomes

The catalog of cancer driver mutations in protein-coding genes has greatly expanded in the past decade. However, non-coding cancer driver mutations are less well-characterized and only a handful of recurrent non-coding mutations, most notably TERT promoter mutations, have been reported. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole g

Cancer LncRNA Census reveals evidence for deep functional conservation of long noncoding RNAs in tumorigenesis

Long non-coding RNAs (lncRNAs) are a growing focus of cancer genomics studies, creating the need for a resource of lncRNAs with validated cancer roles. Furthermore, it remains debated whether mutated lncRNAs can drive tumorigenesis, and whether such functions could be conserved during evolution. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, we introduce th

Reaktorhallen: Violin Solo

In 2021, I had a residency in "Reaktorhallen" (The Reactor Hall, or "R1"), a former nuclear reactor hall on the campus of Kunliga Tekniska Högskolan (the Royal Institute of Technology, or "KTH"). I was there to make a work for the Skandia organ, a former cinema organ that is housed in R1. I also worked with the violin in the space, and played an improvisation from this material on the concert I di

Acute burn care and outcomes at the Hospital Nacional Guido Valadares (HNGV), Timor-Leste : A 7-year retrospective study

The purpose of this study was to describe the epidemiology of patients presenting with acute burns and undergoing admission at Hospital Nacional Guido Valadares (HNGV) in Dili, Timor-Leste in the period 2013 to 2019. HNGV is the only tertiary referral hospital in Timor-Leste. This was a retrospective study involving all acute burn patients admitted to the surgical wards of HNGV from 2013 to 2019.
