    Abstract The coupling of a two-level system with an electromagnetic field, whose fully quantized version is the quantum Rabi model, is among the central topics of quantum physics. When the coupling strength becomes large enough that the field mode frequency is reached, the deep strong coupling regime is approached, and excitations can be created from the vacuum. Here we demonstrate a periodic variant of the quantum Rabi model in which the two-level system is encoded in the Bloch band structure of cold rubidium atoms in optical potentials. With this method we achieve a Rabi coupling strength of 6.5 times the field mode frequency, which is far in the deep strong coupling regime, and observe a subcycle timescale raise in bosonic field mode excitations. In a measurement recorded in the basis of the coupling term of the quantum Rabi Hamiltonian, a freezing of dynamics is revealed for small frequency splittings of the two-level system, as expected when the coupling term dominates over all other energy scales, and a revival for larger splittings. Our work demonstrates a route to realize quantum-engineering applications in yet unexplored parameter regimes.

    Abstract This brief review introduces the reader to tensor network methods, a powerful theoretical and numerical paradigm spawning from condensed matter physics and quantum information science and increasingly exploited in different fields of research, from artificial intelligence to quantum chemistry. Here, we specialize our presentation on the application of loop-free tensor network methods to the study of high-energy physics problems and, in particular, to the study of lattice gauge theories where tensor networks can be applied in regimes where Monte Carlo methods are hindered by the sign problem. This article is part of the theme issue 'Quantum technologies in particle physics'.

    Abstract The Odontites vernus group is the most widespread of the genus Odontites, occupying the temperate regions of Eurasia and northern Morocco. The group contains three species, all inhabiting the Iberian Peninsula, where O. vernus s.l. (sensu lato) exhibits remarkable morphological variability and includes diploid and tetraploid individuals corresponding to the two subspecies that occur there. We collected 301 individuals from 100 sampling sites covering the entire distribution of O. vernus in the Iberian Peninsula and genotyped them using 12 simple sequence repeat (SSR) markers. Their ploidy level was estimated by flow cytometry, and two cpDNA regions (rps16 intron and trnK‐rps16) were sequenced. We found 129 diploids and 172 tetraploids distributed following a mosaic parapatry model, while only two mixed‐ploidy populations were discovered. The 20 haplotypes found fit two well‐defined haplogroups, to some extent correlated with estimated ploidy levels. The frequencies of the SSR alleles shared by both cytotypes, as well as those of the private alleles corresponding to the tetraploid cytotype, indicate that tetraploids likely originated at least twice through autopolyploidy. Additionally, the results from SSR markers were structured in a higher number of groups than did the cpDNA sequences. Thus, the genetic distance analysis detected four groups, but the Bayesian analysis of population structure identified seven, with only low levels of gene flow detected among groups. The distributions of the seven genetic groups coincide with well‐known refugium areas within the Iberian Peninsula during the climatic oscillations of the Quaternary. Thus, the results give additional support to the “refugia within refugia” hypothesis.

    Abstract PREMISE: Ecological drivers for genetic differentiation in Mediterranean climates are still underexplored. We have used the strictly Mediterranean endemic Odontites recordonii as a model species to address this question. This species is one of the three Iberian representatives of the O. vernus group, which are morphologically similar. Thus, it was additionally necessary to clarify their phylogenetic relationships. METHODS: We used amplified fragment length polymorphisms to reveal phylogenetic relationships within O. vernus group, and to reconstruct the phylogeographic patterns within O. recordonii. Additionally, ecological niche models were generated to detect refugia along the Quaternary climatic oscillations. And finally, alleles under natural selection were identified, and correlations between allele presences and environmental variables were calculated in order to shed light on the ecological drivers promoting differentiation. RESULTS: The three species from the O. vernus group were recovered as distinct species. Three genetic groups were found within O. recordonii and a putative refugium was detected for each one. Eighty‐one alleles could be under diversifying selection, and 58 alleles showed significant correlations with environmental variables, especially with temperature and precipitation seasonality and summer drought. CONCLUSIONS: The three Iberian species of the O. vernus group are reciprocal monophyletic taxa. The three genetic groups of O. recordonii could have been restricted to narrow refugia during the Quaternary and displayed present distributions in accordance with bioclimatic conditions. Temperature and precipitation seasonality and the intensity of summer drought are definitory climatic parameters of Mediterranean‐type climates, and they could have acted as drivers of genetic differentiation on O. recordonii.

    Abstract Background: Some women experience voiding dysfunction after stress urinary incontinence (SUI) surgery. We explore if detrusor underactivity (DU) found in urodynamic study (UDS) prior to SUI surgery using an adjustable single incision sling (SIS) may be related to voiding dysfunction after surgery.
    Methods: This is a prospective, diagnostic, transversal, single center study comparing voiding dysfunction after SUI surgery with a SIS (Altis
    Results: A total of 139 women were included, 29 (20.9%) in DU group and 110 (79.1%) in control group. Control and DU groups have shown similar objective (75.5% vs. 71.4% P=0.66) and subjective (85.4% vs. 96.1% P=0.22) success rates, respectively, without statistical differences. Voiding symptoms increased after surgery in both groups (+20.7% DU group vs. +8.1% normal group, P=0.29). More voiding symptoms (persistent/de novo) were found in DU group vs. normal group, but without statistically significant differences.
    Conclusions: According to our results, the presence of DU previous to SUI surgery with a SIS (Altis

    Abstract Techniques of taking casts mainly rely not on the objectivity of the procedure, but on the experience and skill of the technician. The aim of this study was to demonstrate the efficiency of a technique of taking standing foot casts controlled via pressure sensors. In this way, we mean to objectivize the degree of correction. The study was carried out through 150 procedures on 50 feet of 29 patients. The value of the "Heel Symmetry Index" was calculated on three casts in three different situations of the same foot: A first cast in which the subject did not control the position of his/her foot; a second cast where manipulations corrected the foot's pronator position; and a third cast with pressure sensors placed in the subject's heel. This enabled the control and quantification of the pressure during the manipulation when taking the cast. The comparison of the "Heel Symmetry Index" in the different groups showed significant p-values of 0.05. Conclusion: The technique of taking casts controlled by pressure sensors achieved more equilibrated casts with a better symmetry index of the heel's outline.

    Abstract Despite the recent publication of several phylogenies focused on Rhinantheae, which has been expanded to include three Asian endemic genera, few studies so far have dealt with particular genera within the tribe. Here, we focus on Odontites and related genera because of the high morphological variability of the group and its unclear generic boundaries. Phylogenetic analyses were performed for nrDNA (ITS) and cpDNA (trnK region and rps16 intron) datasets, using Bayesian and Parsimony analyses. Our results cast doubt on the inclusion of Pterygiella and related genera within the Rhinantheae and support the para‐ phyly of Phtheirospermum, making it necessary to propose three new combinations to avoid it. Odontites is recircumscribed to include Bartsiella, Bornmuellerantha, and Macrosyringion, but not Odontitella. Within Odontites, five distinct lineages are identified. These are distinguishable either by morphological synapomorphies or by a combination of several character states. Most of the Odontites species are regarded as monophyletic. In the O. vernus and O. luteus complexes, some taxonomic changes are made to avoid paraphyly, which results in three new combinations.

    Abstract PREMISE OF THE STUDY: Microsatellite primers were developed for the first time in the genus Filago (Gnaphalieae: Asteraceae). These markers will facilitate low‐scale phylogenetic, phylogeographic, and population genetic studies within the genus Filago. METHODS AND RESULTS: Ten pairs of polymorphic microsatellite primers (as well as five pairs of monomorphic primers) were identified and optimized on two species of Filago (F. gaditana and F. carpetana) using a microsatellite‐enrichment library method and 454 GS‐FLX technique. The polymorphic primers amplified tri‐ to hexanucleotide repeats and showed one to six alleles per locus for both species. Transferability was performed in 29 samples corresponding to nine representative species of Filago. CONCLUSIONS: The results indicate the utility of the newly developed markers, which will be useful to delve into the phylogenetic relationships among the taxa within Filago. These microsatellites will enable studies of phylogeographic, reproductive, and genetic variation.
