Protein linear indices of the ‘macromolecular pseudograph α-carbon atom adjacency matrix’ in bioinformatics. Part 1: Prediction of protein stability …

2005

Abstract A novel approach to bio-macromolecular design from a linear algebra point of view is introduced. A protein’s total (whole protein) and local (one or more amino acid) linear indices are a new set of bio-macromolecular descriptors of relevance to protein QSAR/QSPR studies. These amino-acid level biochemical descriptors are based on the calculation of linear maps on R n [ f k ( x m i ) : R n → R n ] in canonical basis. These bio-macromolecular indices are calculated from the kth power of the macromolecular pseudograph α-carbon atom adjacency matrix. Total linear indices are linear functional on R n . That is, the kth total linear indices are linear maps from R n to the scalar R [ f k …

Quantum Lower Bound for Graph Collision Implies Lower Bound for Triangle Detection

2015

We show that an improvement to the best known quantum lower bound for GRAPH-COLLISION problem implies an improvement to the best known lower bound for TRIANGLE problem in the quantum query complexity model. In GRAPH-COLLISION we are given free access to a graph $(V,E)$ and access to a function $f:V\rightarrow \{0,1\}$ as a black box. We are asked to determine if there exist $(u,v) \in E$, such that $f(u)=f(v)=1$. In TRIANGLE we have a black box access to an adjacency matrix of a graph and we have to determine if the graph contains a triangle. For both of these problems the known lower bounds are trivial ($\Omega(\sqrt{n})$ and $\Omega(n)$, respectively) and there is no known matching upper …

Interacting With Human Simulations: A Prototype Application

2019

The process of interacting and executing agent-based simulations of human phenomena is complex and difficult to follow for lay people. This is due to 1) limited access to computing power, 2) difficulty in writing analytics scripts and 3) the size and complexity of the simulation space. Consequently, agent-based simulations are normally used once to answer a limited set of questions instead of exploring all the potential paths that the model offers. Here, we describe an approach for developing user experiences that automate the analytic process and rely on interactive visualizations and life histories of societies and agents. This approach helps the user visualize simulation results, pin-poi…

El perfil de aplicación de RDA para monografías antiguas de la Biblioteca Nacional de España

2023

La Biblioteca Nacional de España ha trabajado activamente en la adaptación de RDA a la descripción del libro antiguo desde el año 2015, hasta poder afrontar finalmente desde el año 2020 el paso definitivo: la redacción del perfil de aplicación de RDA para monografías antiguas de la BNE. Este trabajo ha permitido identificar los principales retos de esta aplicación, así como aprovechar las oportunidades que ofrece al catalogador de libro antiguo. Entre los aspectos más novedosos se cuentan instrucciones destinadas a la transcripción, al uso de las menciones de publicación, distribución y fabricación, así como al desarrollo de las relaciones a nivel de manifestación que permitirán por primera…

WiseEye: A Platform to Manage and Experiment on Smart Camera Networks

2016

International audience; Embedded vision is probably at the edge of phenomenal expansion. The smart cameras are embedding some processing units which are more and more powerful. Last decade, high-speed image processing can be implemented on specifically designed architectures [1] nevertheless the designing time of such systems was quite high and time to market therefore as well. Since, powerful chips (i.e System On Chip) and quick prototyping methodologies are contently emerging [2],[3],[4] and enable more complex algorithms to be implemented faster. Moreover, smart cameras which are embedding flexible and powerful multi-core processors or Graphic Processors Unit (GPU) are now available and …

From limit to centrality. Regeneration of the Genoa's port area through architectural and urban design

2012

This survey’s core is the case study of the regeneration of the port area and of the urban waterfront of the city of Genoa, as an emblematic example where the architectural and urban design plays an important role, oriented to the transformation of the port area and to the modification of the relationship that exists between the harbour and the city. In particular this will deepen the possibility, to reverse the condition of limit that characterizes the port area into a new centrality, through the design, passing by intermediate steps that redefine the modalities of access and of connection between city and port, breaking the condition of isolation that ports usually present. As a matter of…

System Times and Channel Availability for Secondary Transmissions in CRNs: A Dependability Theory based Analysis

2017

[EN] Reliability is of fundamental importance for the performance of secondary networks in cognitive radio networks (CRNs). To date, most studies have focused on predicting reliability parameters based on prior statistics of traffic patterns from user behavior. In this paper, we define a few reliability metrics for channel access in multichannel CRNs that are analogous to the concepts of reliability and availability in classical dependability theory. Continuous-time Markov chains are employed to model channel available and unavailable time intervals based on channel occupancy status. The impact on user access opportunities based on channel availability is investigated by analyzing the stead…
