Lax pair and super-Yangian symmetry of the nonlinear super-Schrodinger equation

We consider a version of the nonlinear Schrodinger equation with M bosons and N fermions. We first solve the classical and quantum versions of this equation, using a super-Zamolodchikov-Faddeev (ZF) algebra. Then we prove that the hierarchy associated to this model admits a super-Yangian Y(gl(Mparallel toN)) symmetry. We exhibit the corresponding (classical and quantum) Lax pairs. Finally, we construct explicitly the super-Yangian generators, in terms of the canonical fields on the one hand, and in terms of the ZF algebra generators on the other hand. The latter construction uses the well-bred operators introduced recently. (C) 2003 American Institute of Physics
Huge Progeny Production during the Transient of a Quasispecies Model of Viral Infection, Reproduction and Mutation

Eigen's quasi-species model describes viruses as ensembles of different mutants of a high fitness "master" genotype. Mutants are assumed to have lower fitness than the master type, yet they coexist with it forming the quasi-species. When the mutation rate is sufficiently high, the master type no longer survives and gets replaced by a wide range of mutant types, thus destroying the quasi-species. It is the so-called "error catastrophe". But natural selection acts on phenotypes, not genotypes, and huge amounts of genotypes yield the same phenotype. An important consequence of this is the appearance of beneficial mutations which increase the fitness of mutants. A model has been recently proposed to describe quasi-species in the presence of beneficial mutations. This model lacks the error catastrophe of Eigen's model and predicts a steady state in which the viral population grows exponentially. Extinction can only occur if the infectivity of the quasi-species is so low that this exponential is negative. In this work I investigate the transient of this model when infection is started from a small amount of low fitness virions. I prove that, beyond an initial regime where viral population decreases (and can go extinct), the growth of the population is super-exponential. Hence this population quickly becomes so huge that selection due to lack of host cells to be infected begins to act before the steady state is reached. This result suggests that viral infection may widespread before the virus has developed its optimal form.This work is part of two research projects: MOSAICO, from Ministerio de Educación y Ciencia (Spain) and MODELICO-CM, from Comunidad Autónoma de Madrid (Spain)
Search for a Higgs boson in the mass range from 145 to 1000 GeV decaying
  to a pair of W or Z bosons

A search for a heavy Higgs boson in the H to WW and H to ZZ decay channels is
reported. The search is based upon proton-proton collision data samples
corresponding to an integrated luminosity of up to 5.1 inverse femtobarns at
sqrt(s) = 7 TeV and up to 19.7 inverse femtobarns at sqrt(s) = 8 TeV, recorded
by the CMS experiment at the CERN LHC. Several final states of the H to WW and
H to ZZ decays are analyzed. The combined upper limit at the 95% confidence
level on the product of the cross section and branching fraction exclude a
Higgs boson with standard model-like couplings and decays in the range 145 <
m[H] < 1000 GeV. We also interpret the results in the context of an electroweak
singlet extension of the standard model.Comment: Replaced with published version. Added the journal reference and DOI.

Semiclassical Green's functions and an instanton formulation of
  electron-transfer rates in the nonadiabatic limit

We present semiclassical approximations to Green's functions of
multidimensional systems, extending Gutzwiller's work to the classically
forbidden region. Based on steepest-descent integrals over these functions, we
derive an instanton method for computing the rate of nonadiabatic reactions,
such as electron transfer, in the weak-coupling limit, where Fermi's
golden-rule can be employed. This generalizes Marcus theory to systems for
which the environment free-energy curves are not harmonic and where nuclear
tunnelling plays a role. The derivation avoids using the Im F method or
short-time approximations to real-time correlation functions. A clear physical
interpretation of the nuclear tunnelling processes involved in an
electron-transfer reaction is thus provided. In the following paper, we discuss
numerical evaluation of the formulae.Comment: 16 pages, 5 figures, submitted to the Journal of Chemical Physic
Muon Anomalous Magnetic Moment in SUSY B-L Model with Inverse Seesaw

Motivated by the tension between the Higgs mass and muon g-2 in minimal
supersymmetric standard model (MSSM), we analyze the muon g-2 in supersymmertic
B-L extension of the standard model (BLSSM) with inverse seesaw mechanism. In
this model, the Higgs mass receives extra important radiative corrections
proportional to large neutrino Yukawa coupling. We point out that muon g-2 also
gets significant contribution, due to the constructive interferences of light
neutralino effects. The light neutralinos are typically the MSSM Bino like and
the supersymmetric partner of U(1)_B-L gauge boson (B'-ino). We show that with
universal soft supersymmetry breaking terms, the muon g-2 resides within 2
sigma of the measured value, namely ~17 x 10^-10, with Higgs mass equal to 125
GeV .Comment: 4 pages, 3 Figure
The affective modulation of motor awareness in anosognosia for hemiplegia :
                    Behavioural and lesion evidence

?? 2015 The Authors. Published by Elsevier Ltd. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/).The possible role of emotion in anosognosia for hemiplegia (i.e., denial of motor deficits contralateral to a brain lesion), has long been debated between psychodynamic and neurocognitive theories. However, there are only a handful of case studies focussing on this topic, and the precise role of emotion in anosognosia for hemiplegia requires empirical investigation. In the present study, we aimed to investigate how negative and positive emotions influence motor awareness in anosognosia. Positive and negative emotions were induced under carefully-controlled experimental conditions in right-hemisphere stroke patients with anosognosia for hemiplegia (n = 11) and controls with clinically normal awareness (n = 10). Only the negative, emotion induction condition resulted in a significant improvement of motor awareness in anosognosic patients compared to controls; the positive emotion induction did not. Using lesion overlay and voxel-based lesion-symptom mapping approaches, we also investigated the brain lesions associated with the diagnosis of anosognosia, as well as with performance on the experimental task. Anatomical areas that are commonly damaged in AHP included the right-hemisphere motor and sensory cortices, the inferior frontal cortex, and the insula. Additionally, the insula, putamen and anterior periventricular white matter were associated with less awareness change following the negative emotion induction. This study suggests that motor unawareness and the observed lack of negative emotions about one's disabilities cannot be adequately explained by either purely motivational or neurocognitive accounts. Instead, we propose an integrative account in which insular and striatal lesions result in weak interoceptive and motivational signals. These deficits lead to faulty inferences about the self, involving a difficulty to personalise new sensorimotor information, and an abnormal adherence to premorbid beliefs about the body
Reduction of cardiovascular risk by a sodium bicarbonated mineral water in moderately hypercholesterolemic young adults

Effects of drinking a sodium bicarbonated mineral water on cardiovascular risk in young men and women with moderate cardiovascular risk were studied. Eighteen young volunteers, total cholesterol levels >5.2 mmol/L without any disease participated. The study consisted in two 8-week intervention periods. Subjects consumed, as a supplement of their usual diet, 1 L/d of a control low mineral water followed by 1 L/d of the bicarbonated mineral water (mmol/L: sodium, 48; bicarbonate, 35; and chloride, 17). Determinations were performed at the end of the control water period and weeks 4 and 8 of the bicarbonated water period. Body weight, BMI, blood pressure, dietary intake, total-cholesterol, LDL-cholesterol, HDL-cholesterol, Apo A-I, Apo B, triacylgycerols, glucose, insulin, adiponectin, high sensitivity-C reactive protein (hs-CRP), soluble adhesion molecules (sICAM and sVCAM), sodium and chloride urinary excretion, and urine pH were measured. Dietary intake, body weight and BMI showed no significant variations. Systolic blood pressure decreased significantly after 4 weeks of bicarbonated water consumption without significant differences between the weeks 4 and 8. Significant reductions were observed after bicarbonated water consumption of total cholesterol (by 6.3%, p=0.012), LDL-cholesterol (by 10% p=0.001), total/HDL-cholesterol (p=0.004), LDL/HDL-cholesterol (p=0.001), and Apo B (p=0.017). Serum triacylglycerols, Apo A-I, sICAM-1, sVCAM-1 and hs-CRP levels did not change. Serum glucose values tended to decrease during the bicarbonated water intervention (p=0.056) but insulin levels did not vary. This sodium bicarbonated mineral water improves lipid profile in moderately hypercholesterolemic young men and women and could therefore be applied in dietary interventions to reduce cardiovascular risk.SA Vichy CatalánPeer reviewe
Noninvasive regional cerebral oxygen saturation for neurological prognostication of patients with out-of-hospital cardiac arrest: a prospective multicenter observational study.

[Aim]To investigate the association between regional brain oxygen saturation (rSO2) at hospital arrival and neurological outcomes at 90 days in patients with out-of-hospital cardiac arrest (OHCA). [Methods]The Japan-Prediction of neurological Outcomes in patients post cardiac arrest (J-POP) registry is a prospective, multicenter, cohort study to test whether rSO2 predicts neurological outcomes after OHCA. We measured rSO2 in OHCA patients immediately after hospital arrival using a near-infrared spectrometer placed on the forehead with non-blinded fashion. The primary endpoint was “neurological outcomes” at 90 days after OHCA. [Results]EMS providers are not permitted to terminate CPR in the field in Japan, and so most patients with OHCA who are treated by EMS personnel are transported to emergency hospitals. Among 1017 OHCA patients, 672 patients including 52 comatose patients with pulses detectable (8%) and 620 cardiac arrest patients (92%) at hospital arrival were enrolled prospectively and consecutively. Twenty-nine patients with good neurological outcome had a significantly higher value of rSO2 at hospital arrival than 643 patients with poor neurological outcome (mean [±SD] 55.6 ± 20.8% vs. 19.7 ± 11.0%, p < 0.001). Receiver operating curve analysis indicated an optimal rSO2 cutoff point of >42% for predicting good neurological outcome, with sensitivity 0.79 (95% confidence interval [CI], 0.60?0.92), specificity 0.95 (95% CI, 0.93?0.96), positive predictive value, 0.41 (95% CI, 0.28?0.55), negative predictive value, 0.99 (95% CI, 0.98?1.00), and area under the curve 0.90 (95% CI, 0.88?0.92). [ConclusionThe rSO2 at hospital arrival can predict good neurological outcome at 90 days after OHCA
Does a peer model’s task proficiency influence children’s solution choice and innovation?

The current study investigated whether 4- to 6-year-old children’s task solution choice was influenced by the past proficiency of familiar peer models and the children’s personal prior task experience. Peer past proficiency was established through behavioral assessments of interactions with novel tasks alongside peer and teacher predictions of each child’s proficiency. Based on these assessments, one peer model with high past proficiency and one age-, sex-, dominance-, and popularity-matched peer model with lower past proficiency were trained to remove a capsule using alternative solutions from a three-solution artificial fruit task. Video demonstrations of the models were shown to children after they had either a personal successful interaction or no interaction with the task. In general, there was not a strong bias toward the high past-proficiency model, perhaps due to a motivation to acquire multiple methods and the salience of other transmission biases. However, there was some evidence of a model-based past-proficiency bias; when the high past-proficiency peer matched the participants’ original solution, there was increased use of that solution, whereas if the high past-proficiency peer demonstrated an alternative solution, there was increased use of the alternative social solution and novel solutions. Thus, model proficiency influenced innovation
Orbitals from local RDMFT : are they Kohn-Sham or Natural Orbitals?

Recently, an approximate theoretical framework was introduced, called local reduced density matrix functional theory (local-RDMFT), where functionals of the one-body reduced density matrix (1-RDM) are minimized under the additional condition that the optimal orbitals satisfy a single electron Schrödinger equation with a local potential. In the present work, we focus on the character of these optimal orbitals. In particular, we compare orbitals obtained by local-RDMFT with those obtained with the full minimization (without the extra condition) by contrasting them against the exact NOs and orbitals from a density functional calculation using the local density approximation (LDA). We find that the orbitals from local-RMDFT are very close to LDA orbitals, contrary to those of the full minimization that resemble the exact NOs. Since local RDMFT preserves the good quality of the description of strong static correlation, this finding opens the way to a mixed density/density matrix scheme, where Kohn-Sham orbitals obtain fractional occupations from a minimization of the occupation numbers using 1-RDM functionals. This will allow for a description of strong correlation at a cost only minimally higher than a density functional calculation
The effect of dynamic loading on the shear strength of pyroclastic ash deposits and implications for landslide hazard : the case of Pudahuel Ignimbrite, Chile.

The co-seismic and post-seismic behaviour of pyroclastic ash deposits and its influence on slope stability remains as a challenging subject in engineering geology. Case studies in volcanic areas of the world suggest that soil structural changes caused by seismic shaking results in landslide activity. It is critical to constrain how this kind of soil behaves during coseismic ground shaking, as well as the effects of dynamic loading on shear strength parameters after shaking. Direct shear tests carried out on cineritic volcanic materials from the Pudahuel Ignimbrite Formation in central Chile show a direct effect of cyclic loading on the shear strength and in a minor extent on the rheology. A high apparent cohesion found in monotonic shear tests, likely attributed to suction and cementation, is destroyed by dynamic loading. At the same time, the internal friction angle rises. This defines a differential post-dynamic behaviour depending on normal effective stress conditions, which favour the occurrence of shallow landslides. These results show how the use of shear strength parameters obtained from standard monotonic direct shear tests may produce misleading results when analyzing seismic slope stability in this type of soils
Benchmarking selection of parameter values for the Barcelona basic model.\ud

Seven teams took part in a benchmarking exercise on selection of parameter values for the Barcelona Basic Model\ud
(BBM) from experimental data on an unsaturated soil. All teams were provided with experimental results from 9\ud
tests performed on a compacted soil in order to determine values for the ten BBM soil constants and an initial\ud
value for the hardening parameter. The coordinating team then performed simulations (at stress point level)\ud
with the 7 different sets of parameter values, in order to explore the implications of the differences in parameter\ud
values and hence to investigate the robustness of existing BBM parameter value selection procedures. The major\ud
challenge was found to be selection of values for the constants λ(0), r, β, N(0) and pc and an initial value for the\ud
hardening parameter p0ð0Þ, with the various teams proposing significantly different values for some of these key\ud
parameters. A key lesson emerging from the exercise is the importance of choosing a method for selecting values\ud
for the parameters β and pc which places the main emphasis on attempting to optimise the match to the experimental\ud
spacing of normal compression lines at different values of suction
Evaluating the effectiveness of a Larinier super active baffle fish pass for European river lamprey Lampetra fluviatilis before and after modification with wall-mounted studded tiles.

To help achieve effective longitudinal river connectivity, evaluation of the efficacy of fishway use by upstream-migrating fishes is needed. Larinier super active baffle (SAB) fishways are relatively cheap retrofit fish passes, suitable for low-head barriers, widespread in Europe and the most commonly fitted technical pass in Britain. Their suitability for non-salmonids, however, is poorly quantified. The efficacy of a 15% gradient SAB fishway and effects of flow regime and water temperature were tested for European river lamprey (Lampetra fluviatilis) using passive integrated transponder (PIT) and acoustic telemetry at a Crump weir on the River Derwent, Northeast England. In migration season 2013–14, over a wide range of flows, 90.1% of 350 tagged lamprey entered the fishway. One fish (0.3%) of those that entered the pass ascended successfully, even though measured water velocity was within laboratory-measured performance conditions for this species. Of 29 acoustic-tagged lamprey that visited the weir over the same period, four (13.8%) ascended it directly, during elevated flows. These data suggest that high turbulence and/or the physical characteristics of baffles may inhibit lamprey ascent of the pass. In migration season 2014–15, we tested the effect of adding studded modular plastic tiles adjacent to the fishway wall, employing PIT antennas separately interrogating the entrance and exit of each of the main fishway and tile routes. 85.8% (169) of 197 tagged lamprey entered the fishway, of which 72/169 (42.6%) entered the tile entrance. Passage efficiency of entrants was 7.1% (12/169), all of which used the tiled route. Reduced local flow velocity in combination with increased availability of resting habitat within the tiles may have facilitated increased passage. Although fishway passage efficiency increased after placement of the modular tiles, it remained half that measured for direct weir passage, both of which are inadequate for connectivity restoration. Quantitative tests of studded tiles placed on the sloping downstream weir face by comparison to control conditions may be more effective and are needed. This study demonstrates the importance of carrying out full-scale field tests to supplement possible solutions developed under laboratory conditions
Hartree-Fock Many-Body Perturbation Theory for Nuclear Ground-States

We investigate the order-by-order convergence behavior of many-body
perturbation theory (MBPT) as a simple and efficient tool to approximate the
ground-state energy of closed-shell nuclei. To address the convergence
properties directly, we explore perturbative corrections up to 30th order and
highlight the role of the partitioning for convergence. The use of a simple
Hartree-Fock solution to construct the unperturbed basis leads to a convergent
MBPT series for soft interactions, in contrast to, e.g., a harmonic oscillator
basis. For larger model spaces and heavier nuclei, where a direct high-order
MBPT calculation in not feasible, we perform third-order calculation and
compare to advanced ab initio coupled-cluster calculations for the same
interactions and model spaces. We demonstrate that third-order MBPT provides
ground-state energies for nuclei up into tin isotopic chain that are in
excellent agreement with the best available coupled-cluster results at a
fraction of the computational cost.Comment: 6 pages, 5 figures, 1 tabl
K2-30b and K2-34b: two inflated hot-Jupiters around Solar-type stars

We report the discovery of the two hot-Jupiters K2-30b and K2-34b. The two
planets were detected transiting their main-sequence star with periods $\sim$
4.099 and $\sim$ 2.996 days, in campaigns 4 and 5 of the extension of the
Kepler mission, K2. Subsequent ground-based radial velocity follow-up with
SOPHIE, HARPS-N and CAFE, established the planetary nature of the transiting
objects. We analyzed the transit signal, radial velocity and spectral energy
distributions of the two systems to characterize their properties. Both planets
(K2-30b and K2-34b) are bloated hot-Jupiters (1.25 $R_{\rm Jup}$ and 1.33
$R_{\rm Jup}$) around relatively bright (V =13.5 and V=11.5), slow rotating
main-sequence (G8 and F9) stars. Thus, these systems are good candidates for
detecting the Rossiter-MacLaughlin effect to measure their obliquity and for
atmospheric studies.Comment: 7 pages, 3 figures, 7 tables, accepted for publication in A&
TAPAS IV. TYC 3667-1280-1 b - the most massive red giant star hosting a
  warm Jupiter

We present the latest result of the TAPAS project that is devoted to intense
monitoring of planetary candidates that are identified within the
PennState-Toru\'n planet search.
  We aim to detect planetary systems around evolved stars to be able to build
sound statistics on the frequency and intrinsic nature of these systems, and to
deliver in-depth studies of selected planetary systems with evidence of
star-planet interaction processes.
  The paper is based on precise radial velocity measurements: 13 epochs
collected over 1920 days with the Hobby-Eberly Telescope and its
High-Resolution Spectrograph, and 22 epochs of ultra-precise HARPS-N data
collected over 961 days.
  We present a warm-Jupiter ($T_{eq}=1350 K$, $m_{2} sin i=5.4\pm$0.4$M_{J}$)
companion with an orbital period of 26.468 days in a circular ($e=0.036$) orbit
around a giant evolved ($\log g=3.11\pm0.09$, $R=6.26\pm0.86R_{\odot}$) star
with $M_{\star}=1.87\pm0.17M_{\odot}$. This is the most massive and oldest star
found to be hosting a close-in giant planet. Its proximity to its host
($a=0.21au$) means that the planet has a $13.9\pm2.0\%$ probability of
transits; this calls for photometric follow-up study.
  This massive warm Jupiter with a near circular orbit around an evolved
massive star can help set constraints on general migration mechanisms for warm
Jupiters and, given its high equilibrium temperature, can help test energy
deposition models in hot Jupiters.Comment: 5 pages, 3 figures, accepted by A&
