Multi-dimensional entanglement generation with multi-core optical fibers
Trends in photonic quantum information follow closely the technical progress
in classical optics and telecommunications. In this regard, advances in
multiplexing optical communications channels have also been pursued for the
generation of multi-dimensional quantum states (qudits), since their use is
advantageous for several quantum information tasks. One current path leading in
this direction is through the use of space-division multiplexing multi-core
optical fibers, which provides a new platform for efficiently controlling
path-encoded qudit states. Here we report on a parametric down-conversion
source of entangled qudits that is fully based on (and therefore compatible
with) state-of-the-art multi-core fiber technology. The source design uses
modern multi-core fiber beam splitters to prepare the pump laser beam as well
as measure the generated entangled state, achieving high spectral brightness
while providing a stable architecture. In addition, it can be readily used with
any core geometry, which is crucial since widespread standards for multi-core
fibers in telecommunications have yet to be established. Our source represents
an important step towards the compatibility of quantum communications with the
next-generation optical networks.Comment: 9 pages, 7 figure
Oral manifestations of Wolf-Hirschhorn syndrome: genotype-phenotype correlation analysis
Background: Wolf-Hirschhorn syndrome (WHS) is a rare disease caused by deletion in
the distal moiety of the short arm of chromosome 4. The objectives of this study were to report
the most representative oral findings of WHS, relate them with other clinical characteristics of
the disease, and establish possible phenotype-genotype correlation. Methods: The study was
conducted at 6 reference centers distributed throughout Spain during 2018–2019. The study
group consisted of 31 patients with WHS who underwent a standardized oral examination.
Due to behavioral reasons, imaging studies were performed on only 11 of the children 6 years
of age or older. All participants had previously undergone a specific medical examination
for WHS, during which anatomical, functional, epilepsy-related, and genetic variables were
recorded. Results: The most prevalent oral manifestations were delayed tooth eruption (74.1%),
bruxism (64.5%), dental agenesis (63.6%), micrognathia (60.0%), oligodontia (45.5%), and
downturned corners of the mouth (32.3%). We detected strong correlation between psychomotor
delay and oligodontia (p = 0.008; Cramér’s V coefficient, 0.75). The size of the deletion was
correlated in a statistically significant manner with the presence of oligodontia (p = 0.009 ;
point-biserial correlation coefficient, 0.75). Conclusion: Certain oral manifestations prevalent in
WHS can form part of the syndrome’s phenotypic variability. A number of the characteristics
of WHS, such as psychomotor delay and epilepsy, are correlated with oral findings such
as oligodontia and bruxism. Although most genotype-phenotype correlations are currently
unknown, most of them seem to be associated with larger deletions, suggesting that some
oral-facial candidate genes might be outside the critical WHS region, indicating that WHS is a
contiguous gene syndrome
Filtration–UV irradiation as an option for mitigating the risk of microbiologically influenced corrosion of subsea construction alloys in seawater
The effect of filtration-UV irradiation of seawater on the biofilm activity on several offshore structural alloys was evaluated in a continuous flow system over 90 days. Biofilms ennobled the electrode potential by +400–500 mV within a few days of exposure to raw untreated seawater. Filtration-UV irradiation of the seawater delayed the ennoblement of the steels for up to 40 days and lowered localized corrosion rates in susceptible alloys. Ennobling biofilms were composed of microbial cells, diatoms and extracellular polymeric substances and the bacterial community in biofilms was affected by both the alloy composition and seawater treatment
Thermographic imaging in sports and exercise medicine: A Delphi study and consensus statement on the measurement of human skin temperature
This is an accepted manuscript of an article published by Elsevier in Journal of Thermal Biology on 18/07/2017, available online: https://doi.org/10.1016/j.jtherbio.2017.07.006
The accepted version of the publication may differ from the final published version.© 2017 Elsevier Ltd The importance of using infrared thermography (IRT) to assess skin temperature (tsk) is increasing in clinical settings. Recently, its use has been increasing in sports and exercise medicine; however, no consensus guideline exists to address the methods for collecting data in such situations. The aim of this study was to develop a checklist for the collection of tsk using IRT in sports and exercise medicine. We carried out a Delphi study to set a checklist based on consensus agreement from leading experts in the field. Panelists (n = 24) representing the areas of sport science (n = 8; 33%), physiology (n = 7; 29%), physiotherapy (n = 3; 13%) and medicine (n = 6; 25%), from 13 different countries completed the Delphi process. An initial list of 16 points was proposed which was rated and commented on by panelists in three rounds of anonymous surveys following a standard Delphi procedure. The panel reached consensus on 15 items which encompassed the participants’ demographic information, camera/room or environment setup and recording/analysis of tsk using IRT. The results of the Delphi produced the checklist entitled “Thermographic Imaging in Sports and Exercise Medicine (TISEM)” which is a proposal to standardize the collection and analysis of tsk data using IRT. It is intended that the TISEM can also be applied to evaluate bias in thermographic studies and to guide practitioners in the use of this technique.Published versio

Outbreak of swine influenza in Argentina reveals a non-contemporary human H3N2 virus highly transmissible among pigs
Sporadic outbreaks of human H3N2 influenza A virus (IAV) infections in swine populations have been reported in Asia, Europe and North America since 1970. In South America, serological surveys in pigs indicate that IAVs of the H3 and H1 subtypes are currently in circulation; however, neither virus isolation nor characterization has been reported. In November 2008, an outbreak of respiratory disease in pigs consistent with swine influenza virus (SIV) infection was detected in Argentina. The current study describes the clinical epidemiology, pathology, and molecular and biological characteristics of the virus. Phylogenetic analysis revealed that the virus isolate shared nucleotide identities of 96-98% with H3N2 IAVs that circulated in humans from 2000 to 2003. Antigenically, sera from experimentally inoculated animals cross-reacted mainly with noncontemporary human-origin H3N2 influenza viruses. In an experimental infection in a commercial swine breed, the virus was of low virulence but was transmitted efficiently to contact pigs and caused severe disease when an infected animal acquired a secondary bacterial infection. This is the first report of a wholly human H3N2 IAV associated with clinical disease in pigs in South America. These studies highlight the importance of two-way transmission of IAVs and SIVs between pigs and humans, and call for enhanced influenza surveillance in the pig population worldwide.Facultad de Ciencias Veterinaria
