Weak Decay Process of $B \to ρ\ell \barν_\ell$: A Varying External Field Approach in QCD Sum Rules

description: A varying external field approach in QCD sum rules is formulated in a systematic way to treat the weak decay form factors and their $q^2$ dependence in the process of $B \to ρ\ell \barν_\ell$. From the form factor sum rules, we can also obtain the mass sum rules for B and $ρ$ mesons, which can help us determine the reliable Borel windows in studying the relevant form factor sum rules. In this way, we thus demonstrate that some QCD sum rule calculations in the literature are less reliable. We also include induced condensate contributions, which have been ignored, into the relevant sum rules. We obtain the ratios $Γ(\bar B^0\toρ^+ e^- \barν_e)$/ $Γ(\bar B^0\toπ^+ e^- \barν_e)$$\approx$ 0.94 and $Γ(\bar B^0\toρ^+ τ^- \barν_τ)$/ $Γ(\bar B^0\toπ^+ τ^- \barν_τ)$ $\approx$ 1.15. We apply this approach to re-examine the case of the $D$ meson decay.

description: Recent topological band theory distinguishes electronic band insulators with respect to various symmetries and topological invariants, most commonly, the time reversal symmetry and the $\rm Z_2$ invariant. The interface of two topologically distinct insulators hosts a unique class of electronic states -- the helical states, which shortcut the gapped bulk and exhibit spin-momentum locking. The magic and so far elusive property of the helical electrons, known as topological protection, prevents them from coherent backscattering as long as the underlying symmetry is preserved. Here we present an experiment which brings to light the strength of topological protection in one-dimensional helical edge states of a $\rm Z_2$ quantum spin-Hall insulator in HgTe. At low temperatures, we observe the dramatic impact of a tiny magnetic field, which results in an exponential increase of the resistance accompanied by giant mesoscopic fluctuations and a gap opening. This textbook Anderson localization scenario emerges only upon the time-reversal symmetry breaking, bringing the first direct evidence of the topological protection strength in helical edge states.

description: Cette note d’orientation politique analyse les données collectées dans Togo peu de temps avant que les vaccins ont été officiellement approuvé. Nous avons mené une enquête téléphonique représentative au Togo (N = 1558) en décembre 2020, peu avant l’arrivée des premiers lots de vaccins Oxford AstraZeneca au Togo à travers l’initiative COVAX. Dans nos analyses, nous avons opérationnalisé l’hésitation à se faire vacciner par le choix par les répondants des options « non » et « je ne sais pas » à la question: « Lorsqu’un vaccin contre la COVID-19 devient disponible, souhaitez-vous vous faire vacciner ? » Nous espérons que nos résultats fournissent des informations utiles sur les facteurs socioéconomique et psychologique associés à l’hésitation à se faire vacciner contre la COVID-19 au Togo.
 Les taux d’hésitation à la vaccination étaient assez élevés, avec 67,7% des répondants togolais qui ont déclaré qu’ils étaient prêts à être vaccines contre la COVID-19 lorsqu’on leur en offrirait- l’opportunité, 25,7% ont déclaré qu’ils ne l’étaient pas et 6,6% étaient indécis. Pour les 25,7% de répondants qui ont manifesté une réticence à se faire vacciner, nous avons posé d’autres questions sur les raisons de cette réticence. Au sein de cette population hésitante, les raisons comprenaient le fait de croire que le vaccin était dangereux (90,6%), la méfiance envers le gouvernement (40,7%), la méfiance envers les firmes pharmaceutiques (15,6%), le fait de croire que la COVID-19 n’est pas assez sévère (7,8%), et d’autres raisons telles que ne pas avoir assez informations sur le vaccin (25,5%).

description: Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated. Aims. We want to bring observational constraints to a large population of intermediate-mass pre-main sequence (PMS) stars in order to test the theory that convective-dynamo fields generated during the PMS phases of stellar evolution can occasionally relax into fossil fields on the main sequence. Methods. Using distance estimations, photometric measurements, and spectropolarimetric data from HARPSpol and ESPaDOnS of 38 intermediate-mass PMS stars, we determined fundamental stellar parameters (Teff, L and v sin i) and measured surface magnetic field characteristics (including detection limits for non-detections, and longitudinal fields and basic topologies for positive detections). Using PMS evolutionary models, we determined the mass, radius, and internal structure of these stars. We compared different PMS models to check that our determinations were not model-dependant. We then compared the magnetic characteristics of our sample accounting for their stellar parameters and internal structures. Results. We detect magnetic fields in about half of our sample. About 90% of the magnetic stars have outer convective envelopes larger than ~25% of the stellar radii, and heavier than ~2% of the stellar mass. Going to higher mass, we find that the magnetic incidence in intermediate-mass stars drops very quickly, within a time-scale of the order of few times 0.1 Myr. Finally, we propose that intermediate-mass T Tauri stars with large convective envelopes, close to the fully convective limit, have complex fields and that their dipole component strengths may decrease as the sizes of their convective envelopes decrease, similar to lower-mass T Tauri stars.

description: We (re) consider in this paper the problem of tunneling through an impurity in a quantum wire with arbitrary Luttinger interaction parameter. By combining the integrable approach developed in the case of Quantum Hall edge states with the introduction of radiative boundary conditions to describe the adiabatic coupling to reservoirs, we are able to obtain the exact equilibrium and non equilibrium current. One of the most striking features observed is the appearance of negative differential conductances out of equilibrium in the strongly interacting regime g <=.2. In spite of the various charging effects, a remarkable form of duality is still observed. New results on the computation of transport properties in integrable impurity problems are gathered in appendices. In particular, we prove that the TBA results satisfy a remarkable relation, originally derived using the Keldysh formalism, between the order T^2 correction to the current out of equilibrium and the second derivative of this current at T=0 with respect to the voltage.

description: The medications in use for treating migraine are directed either towards inhibiting the characteristic migraine pain or towards preventing it from occurring. In this pursuit, ergotamine and sumatriptan class of 5-HT1B receptor agonists have been proved to be extremely effective. Further research into this field led us to design cyanopyridone derivatives that were synthesized through cyclization of 2-cyano-N-phenylacetamides with malonitrile and 2,3-dihydrobenzo[b][1,4]dioxine-6-carbaldehyde. The synthesized cyanopyridones analogs, when docked with active site of 5-HT1B receptor, showed better binding affinity compared to standard antimigraine medications. Additionally, in silico ADME prediction for drug-likeness and pharmacokinetics revealed that all compounds are safer and can be used as antimigraine medicine. The structure of the synthesized compounds has been elucidated on the basis of spectral analysis.

description: We study how star formation (SF) is quenched in low-redshift disk galaxies with integral-field spectroscopy. We select 131 face-on spiral galaxies with stellar mass greater than $\rm 3\times10^{10}M_\odot$, and with spatially resolved spectrum from MaNGA DR13. We subdivide the sample into four groups based on the offset of their global specific star formation rate (SFR) from the star-forming main sequence and stack the radial profiles of stellar mass and SFR. By comparing the stacked profiles of quiescent and star-forming disk galaxies, we find that the decrease of the global SFR is caused by the suppression of SF at all radii, but with a more significant drop from the center to the outer regions following an inside-out pattern. As the global specific SFR decreases, the central stellar mass, the fraction of disk galaxies hosting stellar bars, and active galactic nuclei (AGNs; including both LINERs and Seyferts) all increase, indicating dynamical processes and AGN feedback are possible contributors to the inside-out quenching of SF in the local universe. However, if we include only Seyferts, or AGNs with ${\rm EW(Hα)>3Å}$, the increasing trend of AGN fraction with decreasing global sSFR disappears. Therefore, if AGN feedback is contributing to quenching, we suspect that it operates in the low-luminosity AGN mode, as indicated by the increasing large bulge mass of the more passive disk galaxies.

description: Increased concerns on food contaminants draw special attention to food safety regulations. These regulations may have direct impact on food trade. The aim of the paper is to assess the impact of regulations concerning aflatoxin maximum residue limits (MRL) on dried fruits trade. The empirical method we adopt combines both gravity and welfare methodologies in a partial equilibrium context. Findings reveal that the EU regulations act as barriers to trade. Results indicate that the tighter the aflatoxin MRL regulations adopted by the export destinations (importing country), the poorer becomes the export performance of the exporting country. In addition, the results of welfare analysis show that tighter standards impose a burden on foreign producers. While producers of EU enjoy larger producer profits, both domestic and international welfare increase as a result of tighter MRL standards. The findings provide further evidence on the fact that the welfare effect of MRLs is positive and significant, although the effect on trade may be negative. In addition, wider regulatory heterogeneity is found to decrease the value of trade among trading nations.
Semiclassical theory of shot noise in mesoscopic conductors

description: A semiclassical theory is developed for time-dependent current fluctuations in mesoscopic conductors. The theory is based on the Boltzmann-Langevin equation for a degenerate electron gas. The low-frequency shot-noise power is related to classical transmission probabilities at the Fermi level. For a disordered conductor with impurity scattering, it is shown how the shot noise crosses over from zero in the ballistic regime to one-third of the Poisson noise in the diffusive regime. In a conductor consisting of n tunnel barriers in series, the shot noise approaches one-third of the Poisson noise as n goes to infinity, independent of the transparency of the barriers. The analysis confirms that phase coherence is not required for the occurrence of the one-third suppression of the shot noise. The effects of electron heating and inelastic scattering are calculated, by inserting charge-conserving electron reservoirs between segments of the conductor.

description: Nine novel fused indolo [1,8] naphthyridine derivatives were synthesized using the Povarov reaction, in a one-pot system, and were fully characterized by spectroscopic techniques such as FT-IR, NMR, TOF-MS, and elemental analysis. Furthermore, their antibacterial activities against six bacterial strains were assessed. The results of the bioassay demonstrated that compounds 4a, 4c, and 4i showed good inhibitory effect with a MIC value ranging from 0.04687 to 0.09375 µM against Bacillus cereus and Staphylococcus aureus. The toxicity of 4a-i, evaluated through mutagenicity test against Salmonella typhimurium TA 98 and TA100 strains, revealed that there was no significant increase in the number of revertant colonies in comparison with the control, sodium azide.
Doppler Effect Assisted Wireless Communication for Interference Mitigation

description: Doppler effect is a fundamental phenomenon that appears in wave propagation, where a moving observer experiences dilation or contraction of wavelength of a wave. It also appears in radio frequency (RF) wireless communication when there exists a relative movement between the transmitter and the receiver, and is widely considered as a major impairment for reliable wireless communication. The current paper proposes Doppler Assisted Wireless Communication that exploits Doppler effect for co-channel interference mitigation. The proposed system also exploits the propagation environment and the network topology, and consists of an access point with a rotating thin drum antenna. The rotating drum receive antenna is designed in such a way that it shifts the interference signals away from the desired signal band. This paper includes a detailed system model, and the results show that under favourable fading conditions, co-channel interference can be significantly reduced. Therefore, it is anticipated that more sophisticated wireless systems and networks can be designed by extending the basic system proposed herein.

description: We analyze analytically, semi-analytically, and numerically the operation of Cross-Resonance (CR) gate for superconducting qubits (transmons). We find that a relatively simple semi-analytical method gives accurate results for the CNOT-equivalent gate duration and compensating single-qubit rotations. It also allows us to minimize the CNOT gate duration over the amplitude of the applied microwave drive and find dependence on the detuning between the qubits. However, full numerical simulations are needed to calculate intrinsic fidelity of the CR gate. We decompose numerical infidelity into contributions from various physical mechanisms, thus finding the intrinsic error budget. In particular, at small drive amplitudes the CR gate fidelity is limited by imperfections of the target-qubit rotations, while at large amplitudes it is limited by leakage. The gate duration and fidelity are analyzed numerically as functions of the detuning between qubits, their coupling, drive frequency, relative duration of pulse ramps, and microwave crosstalk. The effect of the echo sequence is also analyzed numerically. Our results show that the CR gate can provide intrinsic infidelity of less than $10^{-3}$ when a simple pulse shape is used.

description: Colored and colorless particles that are stable on collider scales and carry exotic electric charges, so-called multiply-charged heavy stable particles (MCHSPs), exist in extensions of the Standard Model, and can include the top partner(s) in solutions of the hierarchy problem. To obtain bounds on color-triplets and color-singlets of charges up to |Q|=8, we recast searches for signatures of two production channels: the "open" channel - where the particles are pair-produced above threshold, and are detectable in dedicated LHC searches for stable multiply charged leptons, and the "closed" channel - where a particle-antiparticle pair is produced as a bound state, detectable in searches for a diphoton resonance. We recast the open lepton searches by incorporating the relevant strong-interaction effects for color-triplets. In both open and closed production, we provide a careful assessment of photon-induced processes using the accurate LUXqed PDF, resulting in substantially weaker bounds than previously claimed in the literature for the colorless case. Our bounds for colored MCHSPs are shown for the first time, as the LHC experiments have not searched for them directly. Generally, we obtain nearly charge-independent lower mass limits of around 970 GeV (color-triplet scalar), 1200 GeV (color-triplet fermion), and 880 - 900 GeV (color-singlet fermion) from open production, and strongly charge-dependent limits from closed production. In all cases there is a crossover between dominance by open and closed searches at some charge. We provide prospective bounds for $\sqrt{s} = 13$ TeV LHC searches at integrated luminosities of 39.5 fb${}^{-1}$, 100 fb${}^{-1}$, and 300 fb${}^{-1}$. Moreover, we show that a joint observation in the open and the closed channels allows to determine the mass, spin, color, and electric charge of the particle.

description: In this paper we study the ground state phase diagram of a one-dimensional $t-U-J$ model, at half-filling. In the large-bandwidth limit and for ferromagnetic exchange with easy-plane anisotropy, a phase with gapless charge and massive spin excitations, characterized by the coexistence of triplet superconducting ($TS$) and spin density wave ($SDW^{z}$) instabilities is realized in the ground state. With reduction of the bandwidth, a transition into an insulating phase showing properties of the spin-1/2 XY model takes place. In the case of weakly anisotropic antiferromagnetic exchange the system shows a long range dimerized (Peierls) ordering in the ground state. The complete weak-coupling phase diagram of the model, including effects of the on-site Hubbard interaction, is obtained.

description: The time evolution of a collisionless plasma is modeled by the relativistic Vlasov-Maxwell system which couples the Vlasov equation (the transport equation) with the Maxwell equations of electrodynamics. We consider the case that the plasma consists of $N$ particle species, the particles are located in a bounded container $Ω\subset\mathbb R^3$, and are subject to boundary conditions on $\partialΩ$. Furthermore, there are external currents, typically in the exterior of the container, that may serve as a control of the plasma if adjusted suitably. We do not impose perfect conductor boundary conditions for the electromagnetic fields, but consider the fields as functions on whole space $\mathbb R^3$ and model objects, that are placed in space, via given matrix-valued functions $\varepsilon$ (the permittivity) and $μ$ (the permeability). A weak solution concept is introduced and existence of global in time solutions is proved, as well as the redundancy of the divergence part of the Maxwell equations in this weak solution concept.

description: We show that in theories in which supersymmetry breaking is communicated by renormalizable perturbative interactions, it is possible to extract the soft terms for the observable fields from wave-function renormalization. Therefore all the information about soft terms can be obtained from anomalous dimensions and beta functions, with no need to further compute any Feynman diagram. This method greatly simplifies calculations which are rather involved if performed in terms of component fields. For illustrative purposes we reproduce known results of theories with gauge-mediated supersymmetry breaking. We then use our method to obtain new results of phenomenological importance. We calculate the next-to-leading correction to the Higgs mass parameters, the two-loop soft terms induced by messenger-matter superpotential couplings, and the soft terms generated by messengers belonging to vector supermultiplets.

description: Purpose- Three of the most common corrosion characterization techniques specifically on Sn-Zn solders will be discussed in this review. The discussion emphasizes on configurations and recent developments on each of characterization techniques of potentiodynamic polarization, potentiostatic polarization and electrochemical impedance spectroscopy were compiled. Design/methodology/approach- The literature review of previous works related to the experimental setups, common parameters and characterization outcomes of Sn-Zn solders, specifically on the morphology, phase and mechanical properties were discussed with help of selected case studies. Findings- The potentiostatic polarization, potentiodynamic polarization and electrochemical impedance spectroscopy provide crucial and significant information on the corrosion properties of Sn-Zn solders. This solder relies heavily on the amount of Zn available due to inability to produce intermetallic compound in between elements. The excellent mechanical properties and low melting temperature of the Sn-Zn solder cannot be denied, but limitations in corrosion resistance open wide opportunities in research to find an improvement. This is to ensure the corrosion performance can be aligned with the outstanding mechanical properties. The advantages, recent trends and important findings of this field were summarized. Originality/value- The unique challenges and future research directions about the corrosion measurement in Sn-Zn solders were shown to highlight rarely discussed risks and problems in lead-free soldering reliability. There are many reviews were made for the Sn-Zn system, but not many cover on corrosion properties. This review focuses on the corrosion characterizations of this alloy system.

description: BACKGROUND AND OBJECTIVES: Fluorescence-guided resection (FGR) of malignant gliomas with five-aminolevulinic acid (5-ALA) is an established method using surgical microscopes equipped with filter systems for observing fluorescence. Over the past decade, new technologies have been introduced for the same purpose, with available publications evaluating their clinical efficacy based on varying criteria. This study aims to review technologies and concepts of validation in the context of 5-ALA–mediated FGR. METHODS: A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement was performed to identify devices capable of detecting 5-ALA–induced fluorescence. Articles found eligible for this review were analyzed, focusing on the methods of validation used for novel devices. A qualitative analysis is presented. RESULTS: Using predefined eligibility criteria, 22 studies were analyzed. Publications on the following visualization devices were reviewed: FL400 (Leica Microsystems), Aeos (Aesculap), BLUE400 and BLUE400 AR Filter System (Carl Zeiss Meditec AG), Endoscope with D-Light C (Karl Storz), Fiberscope N-4L (Machida), ORBEYE 4K 3D Digital Video Microscope (Olympus), and several customized surgical loupe systems. In many cases, validation seemed unstandardized, with inherent biases and limited reproducibility. CONCLUSION: This review illustrates the significance of device validation within the framework of FGR. It emphasizes the criticality of validating devices in accordance with established standard, i.e. the BLUE400 filter system, which was employed in the approval studies of 5-ALA. Furthermore, standardized concepts of validation are required to assess whether new devices are, in fact, a reliable or superior alternative in the field of FGR. Published guidelines should be considered when performing future studies.

description: The main aim of this article is to highlight the importance of syntactical stylistic devices to be able to paraphrase and express thoughts impressively in speaking and writing. Syntactical stylistic devices are based on the syntactical arrangement of the elements of a sentences or a paragraph. Besides there is a comparatively large group of syntactical stylistic devices in which the stylistic effect is achieved not only through a peculiar syntactical structure of the utterance, but also through the employment of the semantical side of its elements. They include inversion, parallelism, climax, repetition, asyndenton, rhetorical question, and question in narrative.

Low frequency shot noise in double-barrier resonant-tunneling structures in a strong magnetic field

description: Low frequency shot noise and dc current profiles for a double-barrier resonant-tunneling structure (DBRTS) under a strong magnetic field applied perpendicular to the interfaces have been studied. Both the structures with 3D and 2D emitter have been considered. The calculations, carried out with the Keldysh Green's function technique, show strong dependencies of both the current and noise profiles on the bias voltage and magnetic field. The noise spectrum appears sensitive to charge accumulation due to barriere capacitances and both noise and dc-current are extremely sensitive to the Landau levels' broadening in the emitter electrode and can be used as a powerful tool to investigate the latter. As an example, two specific shapes of the levels' broadening have been considered - a semi-elliptic profile resulting from self-consistent Born approximation, and a Gaussian one resulting from the lowest order cumulant expansion.

description: The observed dark matter abundance in the Universe can be fully accounted for by a minimally coupled spectator scalar field that was light during inflation and has sufficiently strong self-coupling. In this scenario, dark matter was produced during inflation by amplification of quantum fluctuations of the spectator field. The self-interaction of the field suppresses its fluctuations on large scales, and therefore avoids isocurvature constraints. The scenario does not require any fine-tuning of parameters. In the simplest case of a single real scalar field, the mass of the dark matter particle would be in the range $1~{\rm GeV}\lesssim m\lesssim 10^8~{\rm GeV}$, depending on the scale of inflation, and the lower bound for the quartic self-coupling is $λ\gtrsim 0.45$.

The Search for Neutrino Oscillations numubar->nuebar with KARMEN

Year: 1998
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The neutrino experiment KARMEN is situated at the beam stop neutrino source ISIS. It provides numu's, nue's and numubar's in equal intensities from the pi+ mu+ decay at rest (DAR). The oscillation channel numub->nueb is investigated in the appearance mode with a 56t liquid scintillation calorimeter at a mean distance of 17.7m from the nu source looking for p(nue,e+)n reactions. The cosmic induced background for this oscillation search could be reduced by a factor of 40 due to an additional veto counter installed in 1996. In the data collected through 1997 and 1998 no potential oscillation event was observed. Using a unified approach to small signals this leads to an upper limit for the mixing angle of sin**2(2t) < 1.3x10^{-3} (90%CL) at large Dm**2. The excluded area in (sin**2(2t),Dm**2) covers almost entirely the favored region defined by the LSND numub->nueb evidence.

Dynamic correlations in doped 1D Kondo insulator: Finite-T DMRG study

Publisher: name: arXiv
Year: 1999
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The finite-T DMRG method is applied to the one-dimensional Kondo lattice model to calculate dynamic correlation functions. Dynamic spin and charge correlations, S_f(omega), S_c(omega), and N_c(omega), and quasiparticle density of states rho(omega) are calculated in the paramagnetic metallic phase for various temperatures and hole densities. Near half filling, it is shown that a pseudogap grows in these dynamic correlation functions below the crossover temperature characterized by the spin gap at half filling. A sharp peak at omega=0 evolves at low temperatures in S_f(omega) and N_c(omega). This may be an evidence of the formation of the collective excitations, and this confirms that the metallic phase is a Tomonaga-Luttinger liquid in the low temperature limit.

description: In this research, firstly, some derivatives of sulfur containing [1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one have been synthesized and then they were used for the synthesis of novel derivatives of 6′-amino-2,9′-dioxo-2′-phenyl-9′H-spiro[indoline-3,8′-pyrano[2,3-d][1,3,4]thiadiazolo[3,2-a]pyrimidine]-7′-carbonitriles via a one-pot three-component condensation reaction of 7-hydroxy-2-phenyl-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one derivatives, malononitrile and isatin compounds in the presence of DABCO as a organocatalyst and under solvent-free conditions. In this report, a new family of spiro-pyrano-thiadiazolo-pyrimidine derivatives have been synthesized in short reaction times (10–60 min) and good to excellent yields (80–96%). The structures of all synthesized products have been confirmed by IR, 1H NMR, 13C NMR and mass spectrometry, and the structure of one selected product was characterized by single-crystal X-ray diffraction studies as well.

description: The purpose of this study was to investigate the effects of cooperative learning on academic achievement and attitudes towards cooperative learning of first-year mathematics students at Dilla College of Teacher Education in Ethiopia. In doing so, a quasi-experimental study design was employed. Simple random allocation was conducted, one class (n1 = 38) being considered as the experimental group, and the other class (n2 = 39) being considered as the control group. A pretest was administered for both groups before conducting intervention. After eight weeks of instruction, a post-test was administered for both experimental and control group participants. Data analysis was conducted through a paired t-test to determine performance by comparing the mean of both groups at a p 0.05 level of significance.
The results confirmed that there was a significant difference in mean test scores between the two groups of participants, t = 9.358, p 0.05, with the experimental group scoring higher than the control group. This shows that cooperative learning has great power to improve their academic performance.

description: We study doubly polarised asymmetries of c-cbar and b-bbar mesons in hadro- and photo-production at low transverse momentum in non-relativistic QCD to high orders in the relative velocity of the pair, v. We give the complete set of expressions required for the asymmetries up to order v^9. The asymmetries in the production of eta_{c,b} states are a stable measure of the polarised gluon densities. The asymmetries for chi_{c,b}, J/psi, psi', and the various Upsilon states are stringent tests of the NRQCD scaling relations.
