Neste artigo abordamos a classificação das Ciências Matemáticas do filósofo Francis Bacon (1561-1626), presente nas obras “The Advancement of Learnings” (1605) e “De Dignitate et Augmentis Scientiarum” (1623). Em ambas publicações, Matemática é classificada como uma ciência pertencente à Metafísica, que está inserida Naturais, parte da Filosofia Natural, dentro Filosofia. Apresentaremos um brev...

We report on integrated erbium-doped waveguide lasers designed for silicon photonic systems. The distributed Bragg reflector laser cavities consist of silicon nitride waveguide and grating features defined by wafer-scale immersion lithography and a top erbium-doped aluminum oxide layer deposited as the final step in the fabrication process. The resulting inverted ridge waveguide yields high opt...

In the mammalian testis germline stem cells keep producing many sperms, while there is no direct evidence for the presence of germline stem cells in the ovary. It is widely accepted in mammals that the mature oocytes are supplied from a pool of primordial follicles in the adult ovary. In other vertebrates, such as fish, however, there has been no investigation on the mechanism underlying the hi...

Recent work based on nitrate abundances in polar ice cores has shown that large fluence solar energetic (E > 30 MeV) particle (LSEP) events during the spacecraft era of observations (1960-present) are diminished in comparison with those of some preceding eras detected in the ice cores dating back to 1561. McCracken et al. [McCracken, K.G.. Dreschhoff, G.A.M., Smart, D.F., Shea. M.A. A study of ...

J Bone Joint Surg [Br] 2007;89-B:1561-6. Avascular necrosis of the femoral head creates considerable morbidity in successful renal transplant recipients who are generally young and expect active lifestyles. Total hip replacement is considered the treatment of choice in these patients, but surgeons may be wary because of a supposed increase in the risk of infection and other complications. A rev...

We study several models of directed animals (branched polymers) on a square lattice. We present a transfer matrix method for calculating the properties of these directed animals when the lattice is a strip of finite width. Using the phenomenological renormalization, we obtain accurate predictions for the connective constants and for the exponents describing the length and the width of large ani...

The prolonged civil strife in the North-West Zone of Somalia (Somaliland) has hampered the development of social infrastructure and public health services. There are limited data on HIV/AIDS. In 2004, a sentinel HIV seroprevalence survey was conducted. Blood samples were collected from 1561 women attending antenatal care clinics, 249 tuberculosis (TB) patients and 243 people attending sexually ...

This paper presents some of Santorio's marginalia to his Commentaria in primam fen primi libri Canonis Avicennae (Venice, 1625), which I identified in the Sloane Collection of the British Library in 2016, as well as the evidence for their authorship. The name of the Venetian physician Santorio Santori (1561-1636) is linked with the introduction of quantification in medicine and with the inventi...
