Geometric interpretation of pre-vitrification in hard sphere liquids

We derive a microscopic criterion for the stability of hard sphere configurations, and we show empirically that this criterion is marginally satisfied in the glass. This observation supports a geometric interpretation for the initial rapid rise of viscosity with packing fraction, or pre-vitrification. It also implies that barely stable soft modes characterize the glass structure, whose spatial extension is estimated. We show that both the short-term dynamics and activation processes occur mostly along those soft modes, and we study some implications of these observations. This article synthesizes new and previous results [C. Brito and M. Wyart, Euro. Phys. Letters, {\bf 76}, 149-155, (2006) and C. Brito and M. Wyart, J. Stat. Mech., L08003 (2007) ] in a unified view.Comment: accepted for publication in the Journal of Chemical Physics (added discussion on RCP and ideal glass transition

Extrinsic curvatures of distributions of arbitrary codimension

In this article, using the generalized Newton transformation, we define higher order mean curvatures of distributions of arbitrary codimension and we show that they agree with the ones from Brito and Naveira (Ann. Global Anal. Geom. 18, 371-383 (2000)). We also introduce higher order mean curvature vector fields and we compute their divergence for certain distributions and using this we obtain total extrinsic mean curvatures

Ernesto do Canto, Brito Rebelo e a construção do Arquivo dos Açores

O projecto do Arquivo dos Açores, monumento incontornável na historiografia açoriana devido à iniciativa de Ernesto do Canto (1831-1900), foi possivelmente inspirado na edição dos Portugaliae Monumenta Historica. Ernesto do Canto, para levar a bom termo a edição desta importante colectânea de fontes e estudos, contou com a colaboração de nomes ilustres da cultura açoriana, como Jacinto Inácio de Brito Rebelo (1830-1920), micaelense e oficial de infantaria, cuja associação com o mentor do Arquivo dos Açores aqui pretendemos analisar. A existência no espólio de Ernesto do Canto, depositado na Biblioteca Pública e Arquivo de Ponta Delgada, de um número assaz significativo de cartas a ele dirigidas por Brito Rebelo foi o ponto de partida para este breve estudo, que pretende esboçar a evolução do relacionamento entre duas grandes figuras da história cultural açoriana e apreender melhor o modo como se foi construindo o Arquivo dos Açores, a partir da colaboração de Brito Rebelo. Do vasto corpus epistolar, foram seleccionadas para publicação no Apêndice Documental as espécies consideradas mais relevantes para o esclarecimento da relação entre Brito Rebelo e Ernesto do Canto e do papel que o primeiro desempenhou na elaboração daquele empreendimento historiográfico, documentos esses que nos elucidam também sobre as redes de amizade que uniam Ernesto do Canto e Brito Rebelo a outros açorianos, que, como eles, estavam empenhados na publicação do Arquivo dos Açores.

[Review of] Silvester J. Brito. Looking Through a Squared Off Circle

Twenty two poems shimmer with irridescence [iridescence] in Looking Through a Squared Off Circle. The interaction of shifting colors and tones in Silvester Brito\u27s poems flood the reader\u27s mind with the bittersweet pain and beauty of the American Indian experience

[Review of] Silvester Brito. Red Cedar Warrior

Red Cedar Warrior, the collection of poems by S.J. Brito, is very obvious in its depiction of trepidations against Native Americans, in its mourning for the loss of culture and traditions, and its expression of anger. We easily see the obvious signs of Native Americanism in most of the poems included in his book. The warrior could not be anything other than Native American, astride a pony, feathered and painted. There are the drums, the ceremonial life, the peyote prayers, the shamans, and such references. We easily see the images and hear the voices that most let us know of the poet\u27s intent to share with us a Native American viewpoint. And why not? After all, Brito is a proud descendant of Comanches and Tarascans

Effects of Backpack Load and Trekking Poles on Energy Expenditure During Field Track Walking

This study evaluates the effects of the use of backpack load and trekking poles on feld track walking energy expenditure. Twenty male volunteer pole walkers (age: 22.70 ± 2.89 years; body mass: 77.90 ± 11.19 kg; height: 1.77 ± 0.06 m; percentage of body fat: 14.6 ± 6.0 %) walked at a self-selected pace on a pedestrian feld track over a period of more than six months. Each subject was examined at random based on four walking conditions: non-poles and non-load, with poles and non-load, nonpoles and with load, with poles and with load. Heart rate, oxygen uptake and energy expenditure were continuously recorded by a portable telemetric system. Non-load walking speed was lower during walking with poles when compared with no poles (p ≤ 0.05). Oxygen uptake, energy expenditure and heart rate varied signifcantly across different conditions. Our results suggest that the use of trekking poles does not influence energy expenditure when walking without an additional load, but it can have an effect during backpack load walking. Moreover, our results indicate that the use of trekking poles may not be helpful to lower the exertion perceived by the subjects when walking with an additional load.info:eu-repo/semantics/publishedVersio

Heritage branding orientation: The case of Ach. Brito and the dynamics between corporate and product heritage brands

The notion of heritage branding orientation is introduced and explicated. Heritage branding orientation is designated as embracing both product and corporate brands and differs from corporate heritage brand orientation which has an explicit corporate focus. Empirical insights are drawn from an in-depth and longitudinal case study of Ach. Brito, a celebrated Portuguese manufacturer of soaps and toiletries. This study shows how, by the pursuance of a strategy derived from a heritage branding orientation Ach. Brito – after a prolonged period of decline – achieved a dramatic strategic turnaround. The findings reveal how institutional heritage can be a strategic resource via its adoption and activation at both the product and corporate levels. Moreover, the study showed how the bi-lateral interplay between product and corporate brand levels can be mutually reinforcing. In instrumental terms, the study shows how heritage can be activated and articulated in different ways. For instance, it can re-position both product and/or corporate brands; it can be meaningfully informed by product brand heritage and shape corporate heritage; and can be of strategic importance to both medium-sized and small enterprises
