Solving Systems of Linear Equations: HHL from a Tensor Networks Perspective
We present an algorithm for solving systems of linear equations based on the
HHL algorithm with a novel qudits methodology, a generalization of the qubits
with more states, to reduce the number of gates to be applied and the amount of
resources. Based on this idea, we will perform a quantum-inspired version on
tensor networks, taking advantage of their ability to perform non-unitary
operations such as projection. Finally, we will use this algorithm to obtain a
solution for the harmonic oscillator with an external force, the forced damped
oscillator and the 2D static heat equation differential equations.Comment: 7 pages, 7 figure
Graphene Synthesis Using a CVD Reactor and a Discontinuous Feed of Gas Precursor at Atmospheric Pressure
The present work shows a new method in order to cost-effectively achieve the synthesis of graphene by Chemical Vapor Deposition (CVD). Unlike most usual processes, where precursors such as argon, H2, CH4, and high purity copper foil are used, the proposed method has replaced the previous ones by N2, N2 (90%) : H2 (10%), C2H2, and electrolytic copper (technical grade) since the use of industrialized precursors helps reduce production costs. On the other hand, the process was modified from a continuous flow system with vacuum to a discontinuous one at atmospheric pressure, eliminating the use of vacuum pump. In addition, this modification optimized the consumption of gases, which reduced the waste and the emission of pollutant gases into the atmosphere. Graphene films were grown under different gas flowrates and temperatures. Then, the obtained material was characterized by TEM, Raman spectroscopy, and AFM, confirming the presence of few graphene layers. In brief, the growth time was reduced to six minutes with acetylene as a carbon precursor at 1000°C and at atmospheric pressure, with a flow rate of 30 sccm. Finally, the reported conditions can be used for the synthesis of good quality graphene films in industrial applications

Ortega-Garcia, "One-handed Keystroke Biometric Identification Competition", in International Conference on Biometrics, ICB 2015, 58-64This work presents the results of the One-handed Keystroke Biometric Identification Competition (OhKBIC), an official competition of the 8th IAPR International Conference on Biometrics (ICB). A unique keystroke biometric dataset was collected that includes freely-typed long-text samples from 64 subjects. Samples were collected to simulate normal typing behavior and the severe handicap of only being able to type with one hand. Competition participants designed classification models trained on the normally-typed samples in an attempt to classify an unlabeled dataset that consists of normally-typed and one-handed samples. Participants competed against each other to obtain the highest classification accuracies and submitted classification results through an online system similar to Kaggle. The classification results and top performing strategies are described.The authors would like to acknowledge the support from

Comparative dynamics of peritoneal cell immunophenotypes in sheep during the early and late stages of the infection with Fasciola hepatica by flow cytometric analysis
Background: The peritoneal cell populations (PCP) are thought to play a crucial role during the early immune response
in Fasciola hepatica infection while newly excysted juveniles (NEJ) are migrating in the peritoneal cavity (PC) towards the
liver. In this study, we aimed to determine the immunophenotypes of the PCP and to analyse the dynamics of the
recruitment of the PCP during the early and late stage of the infection in sheep infected with F. hepatica.
Methods: Thirty-seven sheep were divided into three groups: Group 1 (n = 20) and 2 (n = 10) were challenged with
F. hepatica, Group 3 (n = 7) was not infected and remained as uninfected control (UC). After the slaughtering, peritoneal
lavages were carried out to isolate peritoneal cell populations at 1, 3, 9 and 18 days post-infection (dpi) for Group 1 and
at 14 weeks post-infection (wpi) for Group 2 and 3. Flow cytometry was conducted to assess the dynamics of peritoneal
cavity cell populations.
Results: TCD4 cells showed a significant decrease at 1 and 18 dpi when compared to UC; no statistical differences were
detected for TCD8 and WC1+
γδ during the early stage of the infection with respect to the UC. CD14 cells exhibited a
decreasing trend, with a significant decrease at 9 and 18 dpi when compared to the UC. The dynamics of MHCII and
CD83 cells showed a similar increasing pattern from 3 to 18 dpi. During the chronic stage, both TCD4 and TCD8 cells
showed no significant differences when compared to the UC, although a slight but statistically significant higher level of
WC1+
γδ cells was observed. A lower percentage of antigen-presenting cells (APCs) was detected with respect to the UC.
Conclusions: The recruitment of the lymphocytes subsets did not show a significant increase during the course of the
infection and only WC1+
γδ cells displayed a significant increase at the chronic stage. For the CD14, a decreasing trend
was observed during the early stage, which was statistically significant at the chronic stage of the infection. Peritoneal
CD83 and MHCII cells developed an increasing trend during the early stage of infection, and showed a significant
decrease at the late stage of the infection.This study was funded by the European Union Grant H2020-635408- PARAGONE and by National Grant AGL2015-67023-C2-1-R.

MSSM Baryogenesis and Electric Dipole Moments: An Update on the Phenomenology
We explore the implications of electroweak baryogenesis for future searches
for permanent electric dipole moments in the context of the minimal
supersymmetric extension of the Standard Model (MSSM). From a cosmological
standpoint, we point out that regions of parameter space that over-produce
relic lightest supersymmetric particles can be salvaged only by assuming a
dilution of the particle relic density that makes it compatible with the dark
matter density: this dilution must occur after dark matter freeze-out, which
ordinarily takes place after electroweak baryogenesis, implying the same degree
of dilution for the generated baryon number density as well. We expand on
previous studies on the viable MSSM regions for baryogenesis, exploring for the
first time an orthogonal slice of the relevant parameter space, namely the
(tan\beta, m_A) plane, and the case of non-universal relative gaugino-higgsino
CP violating phases. The main result of our study is that in all cases lower
limits on the size of the electric dipole moments exist, and are typically on
the same order, or above, the expected sensitivity of the next generation of
experimental searches, implying that MSSM electroweak baryogenesis will be soon
conclusively tested.Comment: 23 pages, 10 figures, matches version published in JHE
