We propose a simple phenomenological parameterization of quint-essence with a time-varying equation of state. In particular, it accounts for the possibility of early dark energy. The quintessence potential can be reconstructed in terms of the present fraction in dark energy, the present equation of state and the amount of early dark energy. Distinguishing quintessence-a time varying dark energy...

We approach a well-known problem: how to relate component physical processes in biological systems to governing imperatives in multiple system levels. The intent is to further practical tools that can be used in the clinical context. An example proposes a formal type system that would support this kind of reasoning, including in machines. Our example is based on a model of the connection betwee...

Kato and Struppa (1999) proposed the notion of autofunctor. In the present paper, the meanings of this notion are analysed in the light of a proposed structural-phenomenological interpretation of the theory of categories (Draganescu 2000). The autofunctor may become important for phenomenological categories. It represents an informational and physical process, not only a mathematical notion. It...

The Dark Matter problem is one of the most relevant quests for the understanding of the elementary constituents of the Universe: the nature of the Dark Matter is still unveiled. Experimental efforts aiming to detect the Dark Matter have shown a great progress in the last decade. This work is devoted to the phenomenological and astroparticle studies of Dark Matter candidates of supersymmetric na...

Phenomenological researchers generally agree that our central concern is to return to embodied, experiential meanings aiming for a fresh, complex, rich description of a phenomenon as it is concretely lived. Yet debates abound when it comes to deciding how best to carry out this phenomenological research in practice. Confusion about how to conduct appropriate phenomenological research makes our ...

These notes summarize a set of lectures on phenomenological quantum gravity which one of us delivered and the other attended with great diligence. They cover an assortment of topics on the border between theoretical quantum gravity and observational anomalies. Specifically, we review non-linear relativity in its relation to loop quantum gravity and high energy cosmic rays. Although we follow a ...

Cells exhibit qualitatively different behaviors on substrates with different rigidities. The fact that cells are more polarized on the stiffer substrate motivates us to construct a two-dimensional cell with the distribution of focal adhesions dependent on substrate rigidities. This distribution affects the forces exerted by the cell and thereby determines its motion. Our model reproduces the ex...

Some renormalization group approaches have been proposed during the last few years which are close in spirit to the Nightingale phenomenological procedure. In essence, by exploiting the finite size scaling hypothesis, the approximate critical behavior of the model on infinite lattice is obtained through the exact computation of some thermal quantities of the model on finite clusters. In this wo...
