Técnicas de etiquetado de señales ópticas en redes de conmutación de ráfagas
En este artículo presentamos una revision de los
asuntos mas importantes relacionados con las redes
de conmutacion de ráfagas de señales ópticas
etiquetadas (LOBS - Labeled optical burst switched)
y las tecnologias que permitiran en un futuro
disponer de redes totalmente ópticas. La
conmutacion de ráfagas de señales ópticas
etiquetadas permite de un modo rapido y con un
mecanismo eficiente de enrutamiento, el
direccionamiento de paquetes/ráfagas sobre redes
multiplexadas por división de onda (WDM -
Wavelength división multiplexing). Por otro lado, y
debido a que se unifica el algoritmo de enrutamiento
y tiene una baja latencia, esta tecnologia es
facilmente escalable hasta rangos de Terabits.Peer Reviewe
In-band time-to-live signaling system for combined DPSK/SCM scheme in OLS
We propose and validate experimentally a time-to-live (TTL) signaling system for an optical label swapping scheme based on 10-Gb/s differential phase-shift-keying (DPSK) packets and with 100-Mb/s subcarrier multiplexing (SCM) label. The proposed scheme allows fast packet discarding by using a 3-GHz subcarrier tone. DPSK payload has only a 2.4-dB power penalty at 10-9 bit-error rate after superimposing the SCM and TTL labeling signal
Kernel-PCA data integration with enhanced interpretability
Background Nowadays, combining the different sources of information to improve the biological knowledge available is a challenge in bioinformatics. One of the most powerful methods for integrating heterogeneous data types are kernel-based methods. Kernel-based data integration approaches consist of two basic steps: firstly the right kernel is chosen for each data set; secondly the kernels from the different data sources are combined to give a complete representation of the available data for a given statistical task. Results We analyze the integration of data from several sources of information using kernel PCA, from the point of view of reducing dimensionality. Moreover, we improve the interpretability of kernel PCA by adding to the plot the representation of the input variables that belong to any dataset. In particular, for each input variable or linear combination of input variables, we can represent the direction of maximum growth locally, which allows us to identify those samples with higher/lower values of the variables analyzed. Conclusions The integration of different datasets and the simultaneous representation of samples and variables together give us a better understanding of biological knowledge
Anàlisi de la producció i la promoció d’esdeveniments culturals a Benimodo
Aquesta proposta de TFG pretén analitzar el procés d'elaboració i de promoció d un esdeveniment cultural al municipi de Benimodo amb l'objectiu de comprovar si les xarxes socials tenen un paper clau en la difusió d'aquest tipus d esdeveniments, i per tant també, al turisme cultural. L'esdeveniment que hem escollit és "Els Premis Literaris Vicent Andrés Estellés" de poesia i narrativa curta que organitza l'Ajuntament de Benimodo cada any en memòria del poeta. A partir de l'anàlisi de la seua producció i promoció actual, es plantejaran alternatives per a millorar la seua difusió a través de les xarxes socials.This TFG proposal aims to analyse the process of elaboration and promotion of a cultural event in the municipality of Benimodo in order to verify if social networks play a key role in the dissemination of this type of event, and therefore, also to cultural tourism. The event we have chosen is the Literary awards of poetry and short narrative that are celebrated in memory of Vicent Andrés Estellés every year in Benimodo. Based on the analysis of its current production and promotion, alternatives will be proposed to improve its dissemination through social networks.Vegas I Grau, A. (2018).

Kernel conditional Embeddings for associating omic data types
Computational methods are needed to combine diverse type of genome-wide data in a meaningful manner. Based on the kernel embedding of conditional probability distributions, a new measure for inferring the degree of association between two multivariate data sources is introduced. We analyze the performance of the proposed measure to integrate mRNA expression, DNA methylation and miRNA expression data
First end-to-end PQC protected DPU-to-DPU communications
The appearance of quantum computing in the short foreseeable future and its capability to break conventional cryptographic algorithms forces to change the paradigm of secure real-time communications. Thus, government organizations, data centers, and enterprises among others are migrating their public key infrastructure towards using post-quantum cryptography (PQC) algorithms in order to mitigate the security threats posed by quantum computers. This letter presents the first quantum resilient secure end-to-end communication link based on PQC algorithms operating between two data-processing units DPU. Both data-processing units employ on-board ARM processors to perform the computationally expensive cryptographic building blocks—in that case CRYSTALS-Kyber as a key encapsulation mechanism and CRYSTALS-Dilithium for digital signature scheme in combination with advanced encryption standard with 256-bit key
