description: Large excess heat is measured in a Pd wire coated with nano-particles. A long (65 cm) and thin (50 μm) Pd wire is coated with thin layers of Pd nano-particles, stabilized against self-sintering by the addition of selected chemical elements: the coating is adhered to the wire surface by heating it in air up to about 800°C. The wire is then heated with up to 1 A of direct current in a pressurized D2 gas atmosphere. The D+ deuterons in the Pd lattice are forced to move toward the cathodic end of the wire because of the voltage drop along the wire (the Cöhn effect). Large excess power density (about 400 W/g of Pd), at high temperatures (up to 400-500°C), is then measured using isoperibolic calorimetry. The reference experiment is made, in situ and without opening the cell, using a Pt wire of same dimensions as the Pd wire, to which was applied the same electrical power. The onset of excess heat occurs in during a phase change from an α + β combined phase of the Pd-D to the α phase, and is proportional to the current density, and to the corresponding voltage drop or input power applied, i.e. the Pd temperature. In the range of temperatures explored up to now, the excess power has exhibited “positive feedback” behaviour versus temperature. This may prove useful to developing future self-sustaining devices for practical applications. No anomalous effects were found using 4He (or Ar, or dry-air) gases.
Superstatistics in high energy physics: Application to cosmic ray energy spectra and e+e- annihilation
Creators: name: Beck, Christian
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We work out a superstatistical description of high-energy scattering processes that takes into account temperature fluctuations in small volume elements. For Gamma-distributed fluctuations of the inverse temperature one effectively obtains formulas similar to those used in nonextensive statistical mechanics, whereas for other temperature distributions more general superstatistical models arise. We consider two main examples: Scattering processes of cosmic ray particles and e+e- annihilation processes. In both cases one obtains excellent fits of experimentally measured energy spectra and cross sections.

subject: SPDE with conservative noise

description: We establish criteria on the chemotactic sensitivity χ for the non-existence of global weak solutions (i.e., blow-up in finite time) to a stochastic Keller–Segel model with spatially inhomogeneous, conservative noise on R^2. We show that if χ is sufficiently large then blow-up occurs with probability 1. In this regime, our criterion agrees with that of a deterministic Keller–Segel model with increased viscosity. However, for χ in an intermediate regime, determined by the variance of the initial data and the spatial correlation of the noise, we show that blow-up occurs with positive probability.
Deep Inelastic Processes and the Equations of Motion
Creators: name: Salvo, Elvio Di
Publisher: name: INFN Open Access Repository
Year: 2009

description: We show that the Politzer theorem on the equations of motion implies  approximate constraints on the quark correlator, restricting considerably,  for sufficiently large $Q^2$, the number of independent distribution  functions that characterize the internal structure of the nucleon, and of independent fragmentation functions. This result leads us to suggesting an alternative method for determining transversity. Moreover our approach implies predictions on the $Q^2$-dependence of some azimuthal  asymmetries, like Sivers, Qiu-Sterman and Collins asymmetry. Lastly, we discuss some implications on the Burkhardt-Cottingham and  Efremov-Leader-Teryaev sum rules.

Structures were elucidated by NMR, HR-ESI-MS, and ECD spectral data analysis. The anti-protozoal activity was evaluated against Leishmania major promastigotes and amastigote-infected macrophages. They showed dose- and time-dependent activity against L. major amastigotes with IC50 values in the range of 4.9 to 25.3 μM being favourably far below their toxicity against normal murine macrophages with CC50 values ranging from 432.5 to 620.7 μM after 48 h of treatment. Compound 3 exhibited the strongest activity and the highest selectivity index (SI) with IC50 of 4.9 ± 0.6 μM and SI of 88.2 comparable with the standard drug, meglumine antimoniate (Glucantime), with IC50 and SI values of 15.5 ± 2.1 μM and 40.0, respectively.

description: To explore the mechanisms underlying the specific inhibitor targeting SGLT-2 empagliflozin in alleviating myocardial ischaemia–reperfusion (I/R) injury. A mouse model of I/R injury and H2O2-induced H9C2 cell model were established. The expressions of Bcl-2, Bax, LC3, Beclin1, GRP78, CHOP, PERK, ATF4, ATF6, IREα and P62 were examined by western blot, immunofluorescence or immunohistochemistry staining, respectively. The cardiac function was measured by echocardiography, TCC staining, lactate dehydrogenase (LDH) and creatine kinase-MB (CK-MB) activity. Cell apoptosis was analysed by TUNEL, Annexin V/propidium iodide (PI) staining and caspase 3 and 9 activities. CCK-8 assay was used for analysing cell viability. PBA, TUDC and 3-MA were utilised for blocking ER stress and autophagy, respectively. Empagliflozin suppressed myocardial I/R injury in vivo and H2O2-induced cardiomyocyte apoptosis in vitro. Blockade of ER stress and autophagy inhibited H2O2-induced cardiomyocyte apoptosis. ER stress activated autophagy through the PERK signalling in H2O2-treated H9C2 cells. Empagliflozin suppressed ER stress-induced autophagy by inhibiting the PERK/ATF4/Beclin1 signalling. H2O2 and I/R-induced cardiomyocyte apoptosis was restrained by empagliflozin through inhibition of ER stress-induced autophagy. Empagliflozin suppressed ER stress-induced autophagy via suppressing the PERK/ATF4/Beclin1 signalling, thus alleviating myocardial I/R injury and cardiomyocyte apoptosis.

Numerical study of Cosmic Ray Diffusion in MHD turbulence

description: We study diffusion of Cosmic Rays (CRs) in turbulent magnetic fields using test particle simulations. Electromagnetic fields are produced in direct numerical MHD simulations of turbulence and used as an input for particle tracing, particle feedback on turbulence being ignored. Statistical transport coefficients from the test particle runs are compared with earlier analytical predictions. We find qualitative correspondence between them in various aspects of CR diffusion. In the incompressible case, that we consider in this paper, the dominant scattering mechanism occurs to be the non-resonant mirror interactions with the slow-mode perturbations. Perpendicular transport roughly agrees with being produced by magnetic field wandering.

description: The Electron Cyclotron Resonance Ion Sources (ECRIS) are nowadays the most effective devices that can feed the particle accelerators in a continuous and reliable way, providing high current beams of multiply charged ions. The heating mechanism of the ECRIS plasma is based on the Electron Cyclotron Resonance, that is able to create multi-keV electrons useful for ionization and to produce a conspicuous number of electrons up to MeV energies, as demonstrated by recent experiments on 3rd generation sources. These electrons are completely useless for the production of highly charged ions (their ionization cross section is very low) and they are also detrimental for the source safety, because they increase the heat load on the superconducting magnets' cryostat, making the magnets operations problematic. With the aim to study alternative plasma heating mechanisms for ECRIS, a series of experimental measurements have been carried out at Max Planck Institute for Plasma Physics of Greifswald, where a Stellarator for nuclear fusion research operates. In the last years it has been demonstrated that the Stellarator plasma can be efficiently heated by means of electrostatic Bernstein waves (BW), generated through an electromagnetic to electrostatic mode conversion mechanism named "OXB-conversion". We will show that a proper BW-heating strongly reduces the number of high energy electrons over a large range of pressure and power. A possible injection scheme for ECRIS-like devices has been designed on this basis and it will be proposed along with a preliminary  modelling of the waves to plasma coupling and wave's path and absorption via OXB-conversion in ECR ion sources.

description: The process p-pbar -> Lambda_c-Antilambda_c is investigated within the handbag approach. It is shown that the dominant dynamical mechanism, characterized by the partonic subprocess u-ubar -> c-cbar factorizes in the sense that only the subprocess contains highly virtual partons, a gluon to lowest order of perturbative QCD, while the hadronic matrix elements embody only soft scales and can be parameterized in terms of helicity flip and non-flip generalized parton distributions. Modelling these parton distributions by overlaps of light-cone wave functions for the involved baryons we are able to predict cross sections and spin correlation parameters for the process of interest.

Limits on Drak Matter WIMPs Using Upward-Going Muons in  the MACRO detector
Creators: name: INFN Collaboration
Publisher: name: INFN Open Access Repository
Year: 1999

description: We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilation of WIMPs trapped in the Sun and Earth. The search is conduced in various angular cones centres on the Sun and Earth to accomodate a range of WIMP masses. No significant excess over the background from atmospheric neutrinos is seen and limits are placed on the upward-going muon fluxes from Sun and Earth. These limits are used to constrain neutralino particle parameters from supersymmetric theory, including those suggested by recent results from DAMA/NaI.

description: 2-Arylmethyl-2,3-dihydro-4(1H)-quinazolinones are a small subgroup of the class of quinazolin-4-one alkaloids, and most published total syntheses require the use of unstable and poorly accessible arylacetaldehydes. Here we show that easily available, stable ω-methoxystyrenes are versatile substitutes for arylacetaldehydes. This new methodology was applied to the total synthesis of the alkaloids glycozolone-A and glycozolone-B. The limitations of this new approach were analyzed as well. In this course, new total syntheses of two 2-arylmethyl-4(1H)-quinazolinone alkaloids (glycosminine, 2-(4-hydroxybenzyl)-4(1H)-quinazolinone) were developed as well.

description: We construct a statistical model of crystal melting to count BPS bound states of D0 and D2 branes on a single D6 brane wrapping an arbitrary toric Calabi-Yau threefold. The three-dimensional crystalline structure is determined by the quiver diagram and the brane tiling which characterize the low energy effective theory of D branes. The crystal is composed of atoms of different colors, each of which corresponds to a node of the quiver diagram, and the chemical bond is dictated by the arrows of the quiver diagram. BPS states are constructed by removing atoms from the crystal. This generalizes the earlier results on the BPS state counting to an arbitrary non-compact toric Calabi-Yau manifold. We point out that a proper understanding of the relation between the topological string theory and the crystal melting involves the wall crossing in the Donaldson-Thomas theory.

description: Clinopodium candidissimum (Munby) Kuntze (Lamiaceae) is used in traditional medicine and as a food condiment in Algeria, where it is known as Zaater cheleuh and Nabta elbida. Here, we report the comprehensive characterisation of non-volatile polar constituents extracted from C. candidissimum aerial parts (a mixture of inflorescences, stems and leaves), and their aroma profile. Qualitative 1H‐NMR and quali-quantitative HPLC-MSn analyses of fractions obtained with solvents at different polarity revealed the presence of aglyconic and glycosylated flavonoids (3.1%), phenylpropanoids (3.6%), gallic acid derivatives (0.76%), and triterpenoids (0.62%), among the others. On the other hand, HS‐SPME-GC-MS allowed to identify 38 volatile constituents, among which the oxygenated monoterpenes pulegone (44.8%), piperitenone (6.6%), isopulegone (5.8%) and neo-menthol (3.8%), and the sesquiterpene hydrocarbons germacrene D (16.2%) and bicyclogermacrene (3.0%) were the most abundant. Overall, results indicate that C. candidissimum represents an endemic natural source of antioxidants and bioactive compounds, and they will be useful for further studies on this species.
An UHV Transportable Container Based on a NEG Pump

Publisher: name: INFN Open Access Repository
Year: 1999

description: Our works concerns the attainment of UHV pressures by using the non evaporable getter (NEG) pump in conjunction with turbomolecular or ion pump of small size. Studies related to surface science show that vacuum conditions in the range of UHV (10-^{10}mbar) are required for very reactive materials, such as niobium or titanium elements. It is a very common practice to perform some surface treatments on these materials and then facing with the problem to preseve the surface state so created from the atmospherical contamination for long times (storing, transport from one laboratory to another, etc.) The aim of this work is to find a vacuum system that is easy to construct, inexpensive and almost completely free from any kind of power supply.

No excess over the expected atmospheric background has been observed. Upper limits have been obtained on the annihilation rate of captured neutralinos in the Sun and converted to limits on the WIMP-proton cross-sections for WIMP masses in the range 250 - 5000 GeV. These results are the most stringent limits to date on neutralino annihilation in the Sun.

description: Secondary metabolites extracted from plants have historically been critical for drug discovery, but their isolation involves expensive and complicated procedures in terms of time and labor resources. Thus, the biogenetic pathway offers the possibility of identifying specific compounds that have not yet been isolated and predicting their isolation from specific natural sources. In plants, biphenanthrenes represent a relatively small group of aromatic secondary metabolites that are considered as important taxonomic markers with promising biological activities. To date, 38 mixed phenanthrenoid dimers have been identified, the biosynthesis of which involves the radical coupling of the two subunits, namely, a phenanthrene and a dihydrophenanthrene. For each of the compounds, it is possible to identify the single phenanthrenic and dihydrophenanthrenic units constituting the considered dimer. Based on the biogenetic pathway, it is possible to identify 19 phenanthrenes and 17 dihydrophenanthrenes, and to distinguish those already known from those not yet isolated. By comparing the results of the possible biosynthetic pathway for each compound with the data in the literature, it is possible to identify three known phenanthrenes and seven known dihydrophenanthrenes, as well as eleven new phenanthrenes and five new dihydrophenanthrenes, and to identify from which plant it is possible to isolate them. This could direct the work of researchers seeking to identify known or new molecules useful for their possible biological properties, and ultimately, to confirm the veracity of the proposed and generally accepted biosynthetic pathway.

description: As of 1 November 2020, estimated case-fatality rates associated with coronavirus disease 2019 are not uniformly patterned across the world and differ substantially in magnitude. Given the global spatial heterogeneity in case-fatality rates, we applied the Blinder-Oaxaca regression decomposition technique to identify how putative sociodemographic, structural, and environmental sources influence variation in case-fatality rates. We show that compositional and associational differences in country-level risk factors explain a substantial proportion of the coronavirus disease 2019-related case-fatality rate gap across nations. Asian countries fair better vis-à-vis case-fatality rate differences mainly due to variation in returns to sociodemographic, structural, and environmental sources among their citizens, relative to those who share similar attributes but live in Europe or North America. The variation in case-fatality rate is driven by Asian populations being better able to buffer the harmful effects of the very risk factors purported to exacerbate the risk of coronavirus disease 2019-related death. The dire circumstances in which we find ourselves demand better understanding of how preexisting conditions across countries contribute to observed disparities in case-fatality rates.

S-duality constraints on 1D patterns associated with fractional quantum Hall states

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Using the modular invariance of the torus, constraints on the 1D patterns are derived that are associated with various fractional quantum Hall ground states, e.g. through the thin torus limit. In the simplest case, these constraints enforce the well known odd-denominator rule, which is seen to be a necessary property of all 1D patterns associated to quantum Hall states with minimum torus degeneracy. However, the same constraints also have implications for the non-Abelian states possible within this framework. In simple cases, including the $ν=1$ Moore-Read state and the $ν=3/2$ level 3 Read-Rezayi state, the filling factor and the torus degeneracy uniquely specify the possible patterns, and thus all physical properties that are encoded in them. It is also shown that some states, such as the "strong p-wave pairing state", cannot in principle be described through patterns.

description: Evidence for a genetic influence on psychological treatment outcome so far has been inconsistent, likely due to the focus on candidate genes and the heterogeneity of the disorders treated. Using polygenic risk scores (PRS) in homogenous patient samples may increase the chance of detecting genetic influences. A sample of 342 phobic patients treated either for clinically relevant dental fear (n = 189) or other (mixed) phobic fears (n = 153) underwent highly standardised exposure-based CBT. A brief five-session format was used to treat dental fear, whereas longer multi-session treatments were used with the mixed-fear cohort. PRS were calculated based on large genetic studies of Neuroticism, Educational Attainment (EA), Intelligence, and four psychopathology domains. We compared PRS of post-treatment and follow-up remitters and non-remitters and regressed PRS on fear reduction percentages. In the dental fear cohort, EA PRS were associated with treatment outcomes, i.e. drop-out, short- and long-term remission state, fear reduction, and attendance of subsequent dental appointments. In the mixed fear treatment cohort, no gene effects were observable. Results indicate the importance of EA-related traits for outcomes following brief, but not long, standardised exposure-based CBT. Such use of PRS may help inform selection and tailoring of treatments.

description: Transcranial magnetic stimulation (TMS) is a well-established and effective treatment for depression, though response rates are suboptimal. Personalising TMS for depression with neuroimaging can take into account inter-individual differences in anatomical and electrophysiological characteristics; and thereby provide a potentially more efficacious form of treatment. The current systematic review aimed to critically appraise the literature relating to personalising TMS for depression with neuroimaging. PubMed, PsycINFO and Embase databases were used to identify relevant literature published up to November 2020. A total of 37 studies were included in the review. Across these studies, a total of 1451 patients with depression received TMS that was personalised using neuroimaging. The majority of the studies used structural or functional neuroimaging to personalise treatment target (n = 30), primarily through neuronavigation methodologies. Fewer studies used electroencephalography to personalise treatment frequency or stimulus timing (n = 7). Only 6 studies directly compared neuroimaging-personalised TMS to standard TMS. The findings from this review suggest that personalising TMS with neuroimaging may be more effective in the treatment of depression compared to standard TMS. Further research is required to directly compare neuroimaging-personalised TMS with standard TMS, and to identify the optimal parameters for treatment personalisation.

description: Gentianopsis is a small gentianaceous genus with a known ethnopharmacological focus as hepatoprotectors containing two underestimated species that are scientifically unexplored: Gentianopsis komarovii (Grossh.) Toyok., which is typical of the Far East, and Gentianopsis stricta (Klotzsch) Ikonn., which is grown in Central Asia. Application of the HPLC-PDA-ESI-tQ-MS/MS technique led to the identification of 28 compounds, such as iridoid glycosides, flavones and xanthones, with loganic acid, sweroside, loganin, secologanin, isoorientin-7-O-glucoside, luteolin-7-O-gentiobioside, chrysoeriol-7-O-glucoside and acacetin-7-O-glucoside being found in the genus for the first time. The extracts of G. komarovii and G. stricta demonstrated choleretic potential, strengthening the bile flow and the total content of bile acids, bilirubin and cholesterol in the bile. The most pronounced effects were observed for luteolin-7-O-glucoside and gentiabavaroside (gentiacaulein-1-O-primveroside), establishing them as the principle choleretics of both herbs. Based on the results, G. komarovii, G. stricta and some phenolic metabolites are prospective new choleretic drugs.

description: We have carried out ab initio electronic structure calculations on graphane (hydrogenated graphene) with single and double vacancy defects. Our analysis of the density of states reveal that such vacancies induce the mid gap states and modify the band gap. The induced states are due to the unpaired electrons on carbon atoms. Interestingly the placement and the number of such states is found to be sensitive to the distance between the vacancies. Furthermore we also found that in most of the cases the vacancies induce a local magnetic moment.

description: Data transfer between two entirely incompatible computers is always a difficult problem to solve. If some time-delay can be accepted in the data transfer, it is possible to port files between a Macintosh and an IBM PC, using a special software package, like LapLink Mac III(1). Here, we present a successful solution of a real-time information exchange between a PS/2 and a Macintosh IIcx. The PS/2, which controls an X-ray powder diffractometer through its manager program, by means of a resident routine seizes the interrupts from the data acquisition units, reads the data and transfers them to the Macintosh. On the Macintosh, a simple program is responsible for the data receipt, display, and save.

description: Chronic and heavy ketamine use has been associated with persistent neurocognitive impairment and structural brain abnormalities. Blood levels of neurofilament light chain (NFL) was recently proposed as a measure of axonal integrity in several neuropsychiatric disorders. We aimed to characterise the axonal neurotoxicity of chronic ketamine use and its relationship to relevant clinical outcomes. We enrolled 65 treatment-seeking ketamine-dependent patients (55 males and 10 females) and 60 healthy controls (51 males and 9 females). Blood NFL levels measured by single molecule array (SiMoA) immunoassay. We compared NFL levels between groups and used regression analyses to identify clinical variables related to NFL levels. Ketamine-dependent patients had significantly higher NFL levels compared to controls (p p p p These results suggest substantial neuroaxonal alterations following chronic and heavy ketamine use. The pronounced increase of NFL levels in the MDD subgroup warrants further investigation of a potential neuroaxonal vulnerability of depressed patients to ketamine.

description: Two new sesquiterpenoids, homalolides C − D (1‒2), were co-isolated from the rhizomes of Homalomena pendula (Blume) Bakh.f collected in Vietnam with five known ones, aromadendrane-4α,10α-diol (3), bullatantriol (4), 1β,4β,6α-trihydroxy-eudesmane (5), 1β,4β,6β-trihydroxyeudesmane (6), and 1β,4β,7α-trihydroxy-eudesmane (7). The structures and relative configuration of new compounds were elucidated by 1 D-/2D-NMR, IR, UV and HRESIMS analyses, and by comparisons to the reported data in the literature. Homalolide C presented an unprecedented skeleton with the 4/8 bicyclic system. All isolates did not exhibit appreciable inhibitory effects on LPS-induced NO production in the RAW 264.7 macrophage cell line and on the growth of human lung cancer cell line (SK-LU-1).

Bright High z SnIa: A Challenge for LCDM?

description: It has recently been pointed out by Kowalski et. al. (arxiv:0804.4142) that there is `an unexpected brightness of the SnIa data at z>1'. We quantify this statement by constructing a new statistic which is applicable directly on the Type Ia Supernova (SnIa) distance moduli. This statistic is designed to pick up systematic brightness trends of SnIa datapoints with respect to a best fit cosmological model at high redshifts. It is based on binning the normalized differences between the SnIa distance moduli and the corresponding best fit values in the context of a specific cosmological model (eg LCDM). We then focus on the highest redshift bin and extend its size towards lower redshifts until the Binned Normalized Difference (BND) changes sign (crosses 0) at a redshift z_c (bin size N_c). The bin size N_c of this crossing (the statistical variable) is then compared with the corresponding crossing bin size N_{mc} for Monte Carlo data realizations based on the best fit model. We find that the crossing bin size N_c obtained from the Union08 and Gold06 data with respect to the best fit LCDM model is anomalously large compared to N_{mc} of the corresponding Monte Carlo datasets obtained from the best fit LCDM in each case. In particular, only 2.2% of the Monte Carlo LCDM datasets are consistent with the Gold06 value of N_c while the corresponding probability for the Union08 value of N_c is 5.3%. Thus, according to this statistic, the probability that the high redshift brightness bias of the Union08 and Gold06 datasets is realized in the context of a (w_0,w_1)=(-1,0) model (LCDM cosmology) is less than 6%. The corresponding realization probability in the context of a (w_0,w_1)=(-1.4,2) model is more than 30% for both the Union08 and the Gold06 datasets.

description: In this paper we present a detailed study of the phase structure in the \β -m plane for Compact Lattice QED. We analyse the scaling properties of the distribution of the partition function zeros in the complex fermion mass plane 4^4, 6^4, 8^4 and 10^4 lattices. The partition function is numerically evaluated by using two independent methods, based respectively on a standard HMC (Hybrid Monte Carlo) and on an alternative approach derived from the MFA (Microcanonical Fermionic Average). The finite size scaling behaviour gives strong indications for a first order phase transition at any value of the fermion mass. The reliability of the result follows from the remarkable agreement between the two independent methods.
