On the linearity of higher-dimensional blocking sets [PDF]

, 2010
A small minimal k-blocking set B in PG(n,q), q = p(t), p prime, is a set of less than 3(q(k)+1)/2 points in PC(n,q), such that every (n - k)-dimensional space contains at least one point of B and such that no proper subset of B satisfies this property ...

Sclerostin regulates bone morphogenetic protein (BMP) bioavailability through interactions with BMP complexes and fibrillin microfibrils

The FEBS Journal, EarlyView.
Sclerostin (SOST) is a multifunctional extracellular modulator of BMP and Wnt signaling. SOST binds with high affinity to fibrillin‐1 and fibrillin‐2, localizing it to fibrillin microfibrils and regulating its extracellular bioavailability. Fibrillin‐bound SOST cannot engage BMP‐7 prodomain (PD) complexes, revealing a competitive mechanism that ...

From Occupational Stigma to Mukti: Liberation, Place, and Agency Among Sex Workers in Sonagachi

Gender, Work &Organization, EarlyView.
ABSTRACT This article examines how former sex workers in Sonagachi, Kolkata, India, navigate occupational and place‐based stigma through spiritual repertoires, of which mukti (liberation) is a central tool. Drawing on critical, embedded ethnography across three fieldwork periods (2001, 2011, and 2019) with long‐term engagement in the Freeset community,

Cyclin‐dependent kinase 13 is indispensable for normal mouse heart development

Journal of Anatomy, Volume 246, Issue 4, Page 616-630, April 2025.
Congenital heart disease (CHD) is the most common defect in live births. The role of cyclin‐dependent kinase (CDK13) in cardiogenesis and CHD was studied using a transgenic mouse model (Cdk13tm1b) carrying deletion of exons 3 and 4, causing loss of function.

Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

Journal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Fracture resistance and behavior of endodontically treated maxillary premolars with varying ferrule heights and post numbers: A laboratory study

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure. Materials and Methods Twenty‐four extracted endodontically treated human maxillary first premolars were divided into three ...

On (k,pe)-arcs in Desarguesian planes

, 2004
In this paper we improve Szőnyi's embeddability result on (k,p)-arcs, in PG(2,q), q=ph, p prime. Szőnyi proved that for k>qp−q+p−ε, ε⩽12q4, a (k,p)-arc can be embedded in a maximal arc.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Equiblocking Sets in K 2,2 -Designs and in K 3,3 -Designs

, 2013
There are many papers in the literature about blocking sets in hypergraphs, including Steiner systems (see references). In this paper we study the existence of equi -blocking sets in K 2,2 -designs and in K 3,3 -designs, determining the spectrum. Further

Harnessing genetic variation for grain quality from diverse wheat landraces

New Phytologist, EarlyView.
Grain protein content is usually measured on bulk samples, hiding variation between individual grains. We used hyperspectral imaging to predict protein in c. 15 000 single grains from over 500 Watkins wheat landraces grown in two environments, resolving both mean protein content and grain‐to‐grain uniformity.
