UM RESGATE HISTÓRICO E FILOSÓFICO DOS ESTUDOS DE CHARLES DU FAY

open access: yesEnsaio Pesquisa em Educação em Ciências, 2015
Charles Du Fay, un filósofo natural del inicio del siglo XVIII, se entregó a una intensa búsqueda por encontrar mecanismos que pudieran explicar ciertos fenómenos eléctricos todavía no comprendidos en su época.

Trade‐offs in avian parental care: a review of theory and meta‐analysis of brood size manipulations

open access: yesBiological Reviews, EarlyView.
ABSTRACT The selective forces shaping parental care have been studied for over 50 years. While theoretical and experimental work has yielded qualitative progress, the large body of empirical work testing predictions about parental investment based on life‐history trade‐offs has yet to be synthesized.

Geometry of Spectral Curves and All Order Dispersive Integrable System [PDF]

open access: yes, 2012
We propose a definition for a Tau function and a spinor kernel (closely related to Baker-Akhiezer functions), where times parametrize slow (of order 1/N) deformations of an algebraic plane curve.

Influence of the Residual Gensini Score on Prognosis of Patients With ST‐Elevation Myocardial Infarction

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The residual Gensini score (rGS) was developed to quantify the severity of coronary atheroma burden after coronary revascularisation. The predictive value of the rGS for clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) remains unexplored.

Predicting cervical cancer DNA methylation from genetic data using multivariate CMMP

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Epigenetic modifications link the environment to gene expression and play a crucial role in tumour development. DNA methylation, in particular, is gaining attention in cancer research, including cervical cancer, the focus of this study.

Search for quark contact interactions and extra spatial dimensions using dijet angular distributions in proton–proton collisions at s=8 TeV

open access: yesPhysics Letters B, 2015
A search is presented for quark contact interactions and extra spatial dimensions in proton–proton collisions at s=8 TeV using dijet angular distributions. The search is based on a data set corresponding to an integrated luminosity of 19.7 fb−1 collected

An annotated checklist of Wisconsin Scarabaeoidea (Coleoptera) [PDF]

open access: yes, 2002
A survey of Wisconsin Scarabaeoidea (Coleoptera) conducted from literature searches, collection inventories, and three years offield work (1997-1999), yielded 177 species representing nine families, two of which, Ochodaeidae and Ceratocanthidae ...

Effect of Late Second to Early Third Trimester of Pregnancy on the Activity of Renal Organic Anion Transporters (OAT1 and OAT3): A Biomarker Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Pregnant individuals take drugs throughout pregnancy and many of these drugs (e.g., antivirals, antibiotics) are eliminated by renal organic anion transporters (OAT) 1 and OAT3. In vivo studies with OAT1/3 substrate drugs suggest that pregnancy increases renal OAT1/3 activities by 1.5‐ to 1.8‐fold.

Search for excited quarks in the γ+jet final state in proton–proton collisions at s=8 TeV

open access: yesPhysics Letters B, 2014
A search for excited quarks decaying into the γ+jet final state is presented. The analysis is based on data corresponding to an integrated luminosity of 19.7 fb−1 collected by the CMS experiment in proton–proton collisions at s=8 TeV at the LHC.

Random matrices, Virasoro algebras, and noncommutative KP

open access: yes, 1998
What is the connection of random matrices with integrable systems? Is this connection really useful? The answer to these questions leads to a new and unifying approach to the theory of random matrices.
