What is computable with limited resources? How can we verify the correctness of computations? How to measure computational power with precision? Despite the immense scientific and engineering progress in computing, we still have only partial answers to these questions. In order to make these problems more precise, we describe an abstract algebraic definition of classical computation, generalizing traditional models to semigroups. The mathematical abstraction also allows the investigation of different computing paradigms (e.g. cellular automata, reversible computing) in the same framework. Here we summarize the main questions and recent results of the research of finite computation. © 2016 IEEE.

We present predictions for multiplicities and single inclusive particle production in proton-lead collisions at the LHC. The main dynamical input in our calculations is the use of solutions of the running coupling Balitsky-Kovchegov equation tested in e+p data. These are incorporated into a realistic model for the nuclear geometry including fluctuations of the nucleon configurations. Particle production is computed via either k t-factorization or the hybrid formalisms to obtain spectra and yields in the central and forward rapidity regions, respectively. These baseline predictions will be useful for testing our current understanding of the dynamics of very strong color fields against upcoming LHC data. © 2012 Elsevier B.V.

Multiplicity fluctuations at midrapidity in pp collisions at high energies are described by a negative binomial distribution and exhibit approximate Koba-Nielsen-Olesen (KNO) scaling. We find that these KNO fluctuations are important also for reproducing the multiplicity distribution in d+Au collisions observed at the Relativistic Heavy-Ion Collider (RHIC), adding to the Glauber fluctuations of the number of binary collisions or participants. We predict that the multiplicity distribution in p+Pb collisions at the Large Hadron Collider (LHC) also deviates little from the KNO scaling function. Finally, we analyze various moments of the eccentricity of the collision zone in A+A collisions at RHIC and LHC and find that particle production fluctuations increase fluctuation dominated moments such as the triangularity ε 3 substantially. © 2012 American Physical Society.

We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields. © 2014 The Authors.

We predict the elliptic flow parameter v2 in U+U collisions at √sNN=200 GeV and in Pb+Pb collisions at √s NN=2.76 TeV using a hybrid model in which the evolution of the quark gluon plasma is described by ideal hydrodynamics with a state-of-the-art lattice QCD equation of state and the subsequent hadronic stage is described by a hadron cascade model. © 2011 American Physical Society.

We analyze the elliptic flow parameter v2 in Pb+Pb collisions at √sNN = 2.76 TeV and in Au+Au collisions at √s NN=200 GeV using a hybrid model in which the evolution of the quark gluon plasma is described by ideal hydrodynamics with a state-of-the-art lattice QCD equation of state, and the subsequent hadronic stage by a hadron cascade model. For initial conditions, we employ Monte Carlo versions of the Glauber and the Kharzeev-Levin-Nardi models and compare results with each other. We demonstrate that the differential elliptic flow v2(pT) hardly changes when the collision energy increases, whereas the integrated v2 increases due to the enhancement of mean transverse momentum. The amount of increase of both v2 and mean pT depends significantly on the model of initialization. © 2011 American Physical Society.

As gentrification processes accelerate in American cities, how do newcomers become solidly in-place while longtime residents become hopelessly out-of-place in neighbourhood public spaces? Bringing focus to the often-overlooked public right-of-way – streets, sidewalks and alleys – I examine social rhythms comprising this network of public spaces when used as an everyday infrastructure of transportation and socialisation or when configured for special events. Using the notion of symbolic economy to link the social production of public space with the municipal regulation of public space, this essay approaches gentrification from three perspectives: conflict, commodification and cosmopolitanism. Focusing on Highland, a rapidly gentrifying neighbourhood in Denver, Colorado, I first delve into skirmishes over street legitimacy. I then unpack quiet workaday measures used by cities to regulate the public right-of-way, namely parking policy and liquor license issuances. I move on to the commodification of ethnic culture by those who ultimately benefit from the displacement of Latino families from North Denver. Lastly, I engage with the concept cosmopolitanism, arguing that diversity discourses, both in the academy and on the street, obscure important relationships between asymmetrically positioned symbolic economies and low-level regulation of public space. Foregrounding routine urban governance over neoliberal agendas, this study critiques gentrification as a commonsense urban policy. © 2015, © Urban Studies Journal Limited 2015.

6th AISB Symposium on Computing and Philosophy: The Scandal of Computation - What is Computation? - AISB Convention 2013 | Year: 2013

The paper answers question "What is computation?" presenting it as a special case of a more general natural process involving dynamics of interacting information systems. For this purpose, a more detailed description of the generalization of Turing machine called symmetric machine outlined in author's earlier paper is used as a model for natural computing in which pro-active character of the machine with differentiated functions of its components (head and tape) is replaced by symmetric interaction of functionally equivalent information systems of hierarchic structure. Turing's A-machine is a special case of such S-machine in which only local states of cell's are changing, but not instructions on the list. The importance of the interactive character of computation is analysed in the context of exclusively interactive processes of mechanics. Causality involved in physical implementations of Turing machine can be preserved in its interactive generalization at the higher, collective level of its structure.

By using Monte-Carlo implementations of kT -factorization formula with runningcoupling BK unintegrated gluon distributions for nucleus-nucleus collisions, we compute higher order harmonic moments of the initial density distribution for both RHIC(Au+Au@200GeV) and LHC(Pb+Pb@2.76TeV) collisions. We study their sensitivity to the size of the valence parton distribution in the nucleon.

Recognition of the need for theoretical biology more than half century ago did not bring substantial progress in this direction. Recently, the need for new methods in science, including physics became clear. The breakthrough should be sought in answering the question "What is life?", which can help to explain the mechanisms of consciousness and consequently give insight into the way we comprehend reality. This could help in the search for new methods in the study of both physical and biological phenomena. However, to achieve this, new theoretical discipline will have to be developed with a very general conceptual framework and rigor of mathematical reasoning, allowing it to assume the leading role in science. Since its foundations are in the recognition of the role of life and consciousness in the epistemic process, it could be called biomathics. The prime candidates proposed here for being the fundamental concepts for biomathics are 'information' and 'information integration', with an appropriately general mathematical formalism. © 2013 Elsevier Ltd.
