Lontostoa, pÀkitteÀ ja örnÀstÀ:deskriptiiviset liikeverbit PienessÀ Kainuun murteen verbisanastossa
TiivistelmĂ€. TĂ€ssĂ€ sanastontutkimusta, sanasemantiikkaa ja deskriptiiviverbien tutkimusta edustavassa pro gradu -tutkielmassa tutkin âPienen Kainuun murteen verbisanastonâ liikeverbien semantiikkaa ja deskriptiivisyyttĂ€. Minna ja Maiju SeppĂ€sen vuodesta 2002 lĂ€htien internetiin kokoamaan sanastoon kuuluu kokonaisuudessaan 132 murreverbiĂ€ merkityksineen ja esimerkkivirkkeineen, mutta varsinainen aineistoni koostuu 40 liikeverbistĂ€. Olen selvittĂ€nyt, kuinka hyvin kunkin aineistossa esitetyn verbin tarkoite vastaa sanakirjoissa olevia samojen sanojen merkityksiĂ€.
PÀÀtavoitteenani on ollut selvittÀÀ kyseisten verbien deskriptiivisyyttÀ aineistoni perusteella sekÀ tehdÀ nÀkyvÀksi se, mikÀ tekee juuri kyseisistÀ verbeistÀ deskriptiivisiÀ. TÀmÀn olen toteuttanut siten, ettÀ olen muodostanut Jarvan (2003) ja JÀÀskelÀisen (2013) vÀitöskirjojen pohjalta seitsemÀn deskriptiivisille verbeille ominaista piirrettÀ. NÀistÀ piirteistÀ muodostetut luokat ovat monimerkityksisyys, merkityksen tilannesidonnaisuus, silmiinpistÀvyys ja affektiivisuus, ÀÀnteellinen variaatio, ÀÀnteiden distribuutio, suosikkijohtimet ja morfologiset kaavat sekÀ esiintyminen koloratiivikonstruktiossa. Olen analysoinut, missÀ aineiston lekseemeissÀ kukin piirre esiintyy ja miten se nÀkyy kyseisten verbien rakenteessa. Piirteiden esiintymismÀÀrÀn perusteella olen tutkinut, mitkÀ sanat ovat erityisen deskriptiivissÀvyisiÀ ja missÀ verbeissÀ piirteitÀ esiintyy vÀhemmÀn.
Aineiston kaikissa 40 sanassa on ÀÀnteiden distribuutiota. Suosikkijohtimia ja affektiivisuutta esiintyy kumpaakin 35 sanassa. MonimerkityksisyyttĂ€ on 32 lekseemissĂ€. ĂĂ€nteellistĂ€ variaatiota on 11 verbissĂ€, neljĂ€ lekseemeistĂ€ esiintyy koloratiivikonstruktiossa, eikĂ€ tilannesidonnaisuutta ole yhdessĂ€kÀÀn aineiston sanoista. Kokonaisuudessaan deskriptiivisiĂ€ piirteitĂ€ esiintyy aineistossa huomattavan paljon, sillĂ€ jokaisessa verbissĂ€ toteutuu 2â5 piirrettĂ€. Piirteiden yleisyys aineistossa osoittaa osaltaan todeksi vĂ€ittĂ€mĂ€n, jonka mukaan Kainuun murteissa, kuten muissakin savolaismurteissa, on erityisen paljon deskriptiivistĂ€ sanastoa.
Valtaosalle aineiston verbeistÀ, jopa 29 lekseemille 40:stÀ, löytyy ainakin lÀheinen merkitys lÀhteiden kanssa. NÀistÀ 17 verbin merkitykset ovat tÀsmÀÀvÀt sekÀ aineistossa ettÀ kÀyttÀmissÀni sanakirjalÀhteissÀ. 12 verbin kohdalla merkitykset ovat lÀheiset, mutta eivÀt aivan vastaavat. Viiden lekseemin merkitykset eroavat toisistaan aineistossa ja lÀhteissÀ, eikÀ kuudesta verbistÀ ole riittÀvÀsti tietoja, jotta semanttinen analyysi olisi mahdollista tehdÀ.
Koska jokaisessa aineiston verbissÀ toteutuu vÀhintÀÀn kaksi deskriptiivistÀ piirrettÀ ja yleensÀ paljon useampi piirre ja kielitajunikin mukaan sanat ovat deskriptiivisiÀ, olen voinut melko yksiselitteisesti todeta kaikki aineiston sanat deskriptiivisiksi tai ainakin deskriptiivissÀvyisiksi. Valtaosalle aineiston verbeistÀ löytyy lÀhteistÀ ainakin lÀheinen merkitys, joten tarkoitteet ovat semanttisesti melko samankaltaisia
Search for new particles in an extended Higgs sector with four b quarks in the final state at s=13TeV
Publisher Copyright: © 2022 The Author(s)A search for a massive resonance X decaying to a pair of spin-0 bosons Ï that themselves decay to pairs of bottom quarks, is presented. The analysis is restricted to the mass ranges mÏ from 25 to 100 GeV and mX from 1 to 3 TeV. For these mass ranges, the decay products of each Ï boson are expected to merge into a single large-radius jet. Jet substructure and flavor identification techniques are used to identify these jets. The search is based on CERN LHC proton-proton collision data at s=13TeV, collected with the CMS detector in 2016â2018, corresponding to an integrated luminosity of 138fbâ1. Model-specific limits, where the two new particles arise from an extended Higgs sector, are set on the product of the production cross section and branching fraction for XâÏÏâ(bbâŸ)(bbâŸ) as a function of the resonances' masses, where both the XâÏÏ and Ïâbb⟠branching fractions are assumed to be 100%. These limits are the first of their kind on this process, ranging between 30 and 1 fb at 95% confidence level for the considered mass ranges.Peer reviewe
Compressive stress-mediated p38 activation required for ER alpha plus phenotype in breast cancer
Breast cancer is now globally the most frequent cancer and leading cause of women's death. Two thirds of breast cancers express the luminal estrogen receptor-positive (ER alpha + ) phenotype that is initially responsive to antihormonal therapies, but drug resistance emerges. A major barrier to the understanding of the ER alpha-pathway biology and therapeutic discoveries is the restricted repertoire of luminal ER alpha + breast cancer models. The ER alpha + phenotype is not stable in cultured cells for reasons not fully understood. We examine 400 patient-derived breast epithelial and breast cancer explant cultures (PDECs) grown in various three-dimensional matrix scaffolds, finding that ER alpha is primarily regulated by the matrix stiffness. Matrix stiffness upregulates the ER alpha signaling via stress-mediated p38 activation and H3K27me3-mediated epigenetic regulation. The finding that the matrix stiffness is a central cue to the ER alpha phenotype reveals a mechanobiological component in breast tissue hormonal signaling and enables the development of novel therapeutic interventions. Subject terms: ER-positive (ER + ), breast cancer, ex vivo model, preclinical model, PDEC, stiffness, p38 SAPK. Reliable luminal estrogen receptor (ER alpha+) breast cancer models are limited. Here, the authors use patient derived breast epithelial and breast cancer explant cultures grown in several extracellular matrix scaffolds and show that ER alpha expression is regulated by matrix stiffness via stress-mediated p38 activation and H3K27me3-mediated epigenetic regulation.Peer reviewe

Phylogeny and Historical Biogeography of Asian Pterourus Butterflies (Lepidoptera: Papilionidae): A Case of Intercontinental Dispersal from North America to East Asia
The phylogenetic status of the well-known Asian butterflies often known as Agehana (a species group, often treated as a genus or a subgenus, within Papilio sensu lato) has long
remained unresolved. Only two species are included, and one of them especially, Papilio
maraho, is not only rare but near-threatened, being monophagous on its vulnerable hostplant, Sassafras randaiense (Lauraceae). Although the natural history and population conservation of âAgehanaâ has received much attention, the biogeographic origin of this group
still remains enigmatic. To clarify these two questions, a total of 86 species representatives
within Papilionidae were sampled, and four genes (concatenated length 3842 bp) were
used to reconstruct their phylogenetic relationships and historical scenarios. Surprisingly,
âAgehanaâ fell within the American Papilio subgenus Pterourus and not as previously suggested, phylogenetically close to the Asian Papilio subgenus Chilasa. We therefore formally
synonymize Agehana with Pterourus. Dating and biogeographic analysis allow us to infer
an intercontinental dispersal of an American ancestor of Asian Pterourus in the early Miocene, which was coincident with historical paleo-land bridge connections, resulting in the
present âEast Asia-Americaâ disjunction distribution. We emphasize that species exchange
between East Asia and America seems to be a quite frequent occurrence in butterflies during the Oligocene to Miocene climatic optima.© 2015 Wu et al. This is an open access

E-cadherin breast tumor expression, risk factors and survival : Pooled analysis of 5,933 cases from 12 studies in the Breast Cancer Association Consortium
E-cadherin (CDH1) is a putative tumor suppressor gene implicated in breast carcinogenesis. Yet, whether risk factors or survival differ by E-cadherin tumor expression is unclear. We evaluated E-cadherin tumor immunohistochemistry expression using tissue microarrays of 5,933 female invasive breast cancers from 12 studies from the Breast Cancer Consortium. H-scores were calculated and case-case odds ratios (OR) and 95% confidence intervals (CIs) were estimated using logistic regression. Survival analyses were performed using Cox regression models. All analyses were stratified by estrogen receptor (ER) status and histologic subtype. E-cadherin low cases (N = 1191, 20%) were more frequently of lobular histology, low grade, > 2 cm, and HER2-negative. Loss of E-cadherin expression (score <100) was associated with menopausal hormone use among ER-positive tumors (ever compared to never users, OR = 1.24, 95% CI = 0.97-1.59), which was stronger when we evaluated complete loss of E-cadherin (i.e. H-score = 0), OR = 1.57, 95% CI = 1.06-2.33. Breast cancer specific mortality was unrelated to E-cadherin expression in multivariable models. E-cadherin low expression is associated with lobular histology, tumor characteristics and menopausal hormone use, with no evidence of an association with breast cancer specific survival. These data support loss of E-cadherin expression as an important marker of tumor subtypes.Peer reviewe
Environmental plastics in the context of UV radiation, climate change, and the Montreal Protocol
There are close links between solar UV radiation, climate change, and plastic pollution. UV-driven weathering is a key process leading to the degradation of plastics in the environment but also the formation of potentially harmful plastic fragments such as micro- and nanoplastic particles. Estimates of the environmental persistence of plastic pollution, and the formation of fragments, will need to take in account plastic dispersal around the globe, as well as projected UV radiation levels and climate change factors. UV radiation, climate change, and plastic pollution are closely interlinked. Existing studies on the persistence of plastics do not fully consider these linkages, challenging global assessments of plastic dispersal, persistence, and weathering. Recently, an Intergovernmental Negotiating Committee was tasked with developing an international binding agreement to end plastic pollution. In response, the UNEP Environmental Effects Assessment Panel assessed effects of UV radiation and interacting climate change factors on plastics, focusing on the durability of products as well as the production and dispersal of micro- and nano-plastic pollutants in the environment
Refined histopathological predictors of BRCA1 and BRCA2 mutation status: A large-scale analysis of breast cancer characteristics from the BCAC, CIMBA, and ENIGMA consortia
Introduction: The distribution of histopathological features of invasive breast tumors in BRCA1 or BRCA2 germline mutation carriers differs from that of individuals with no known mutation. Histopathological features thus have utility for mutation prediction, including statistical modeling to assess pathogenicity of BRCA1 or BRCA2 variants of uncertain clinical significance. We analyzed large pathology datasets accrued by the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA) and the Breast Cancer Association Consortium (BCAC) to reassess histopathological predictors of BRCA1 and BRCA2 mutation status, and provide robust likelihood ratio (LR) estimates for statistical modeling. Methods: Selection criteria for study/center inclusion were estrogen receptor (ER) status or grade data available for invasive breast cancer diagnosed younger than 70 years. The dataset included 4,477 BRCA1 mutation carriers, 2,565 BRCA2 mutation carriers, and 47,565 BCAC breast cancer cases. Country-stratified estimates of the
