Relevance matching between two information objects such as a document and query or a user and product (e.g. movie) is an important problem in information retrieval systems. The most common and most successful way to approach this problem is by probabilistically modelling the relevance between information objects, and computing their relevance matching as the probability of relevance. The object...

The palygorskite-sepiolite group of clay minerals has a wide range of industrial applications derived mainly from its sorptive, rheological and catalytic properties which are based on the fabric, surface area, porosity, crystal morphology, structure and composition of these minerals. For assessing potential industrial uses, the mineralogical and chemical composition of the clay and its basic ph...

Précisons tout de suite que dans ce qui suit, F est un corps extension finie de Qp avec p 6= 2 et même pour le théorème principal p grand. Le but de ce travail est de produire des fonctions sur les groupes p-adiques orthogonaux impairs dont les intégrales orbitales sur les éléments elliptiques réguliers ne dépendent que des classes de conjugaison stable. Au passage, on produit aussi des fonctio...

UNINTENTIONAL weight loss represents a cardinal symptom of frailty in older persons (1–6). Even a small decline in body mass in older persons is associated with mortality (7). Protein energy malnutrition is associated with anemia, pressure ulcers, sarcopenia, bone loss and hip fractures, declining immune function, impaired immune response to vaccinations, infections, cognitive impairment, funct...

The PERK-eIF2α branch of the Unfolded Protein Response (UPR) mediates the transient shutdown of translation in response to rising levels of misfolded proteins in the endoplasmic reticulum. PERK and eIF2α activation are increasingly recognised in postmortem analyses of patients with neurodegenerative disorders, including Alzheimer’s disease, the tauopathies and prion disorders. These are all cha...

A flurry of recent papers have attempted to taxonomically characterise eastern canids, mainly grey wolves Canis lupus, eastern wolves Canis lycaon or Canis lupus lycaon and northeastern coyotes or coywolves Canis latrans, Canis latrans var. or Canis latrans x C. lycaon, in northeastern North America. In this paper, we performed a meta-analysis on northeastern coyote taxonomy by comparing result...

We present tools for 3D object retrieval in which a model, a polygonal mesh, serves as a query and similar objects are retrieved from a collection of 3D objects. Algorithms proceed first by a normalization step (pose estimation) in which models are transformed into a canonical coordinate frame. Second, feature vectors are extracted and compared with those derived from normalized models in the s...

This Perspective briefly reviews the relationship between UV-induced mutations in habitually sun-exposed human skin and subsequent development of actinic keratoses (AKs) cancers. It argues that field therapy rather than AK-selective is more logical approach to cancer prevention hypothesizes treatment early process cancerization, even prior appearance AKs, may be effective preventing as well ben...
