description: Aim To determine the feasibility of using the Mobile Instant Messaging (MIM) platform, WhatsApp, to provide supervision and support for student nurse tutors during a teaching practice placement in Nigeria. Methods A descriptive qualitative method was used to design and evaluate a six-week WhatsApp group discussion intervention among 19 student nurse tutors. Two pre-intervention focus group sessions (n=9 and n=10) and a workshop were conducted to assess the students' content needs and media usage, and to develop a short online supervisory curriculum. To evaluate the intervention, two focus group sessions (n=9 and n=9) were carried out, transcribed verbatim, and analysed together with the actual WhatsApp conversations using thematic content analysis. Findings The participants found the WhatsApp-enabled learning space valuable, in particular for the transfer and application of knowledge in their day-to-day teaching practice and, more generally, for their professional development. There were rich and multifaceted indicators of learning and professional development in evidence which were mostly triggered by specific facilitation techniques. The four themes from the WhatsApp conversations are: (1) sharing and discussing “tricks of the trade”; (2) providing direction and triggering reflective (teaching) practice; (3) sparking professional discussions and announcing professional development opportunities; and (4) maintaining a continuous moderating and teaching “presence”. Conclusion Despite some technical challenges centered mainly on the accessibility of the MIM space, the study identified indicators of good supervision practice and the results point to the feasibility and value of MIM to enhance supervision during teaching practice.

description: We demonstrate a Fock-state filter which is capable of preferentially blocking single photons over photon pairs. The large conditional nonlinearities are based on higher-order quantum interference, using linear optics, an ancilla photon, and measurement. We demonstrate that the filter acts coherently by using it to convert unentangled photon pairs to a path-entangled state. We quantify the degree of entanglement by transforming the path information to polarisation information, applying quantum state tomography we measure a tangle of T=(20+/-9)%.

description: Magnetic reconnection is a ubiquitous phenomenon in turbulent plasmas. It is an important part of the turbulent dynamics and heating of space and astrophysical plasmas. We examine the statistics of magnetic reconnection using a quantitative local analysis of the magnetic vector potential, previously used in magnetohydrodynamics simulations, and now generalized to fully kinetic PIC simulations. Different ways of reducing the particle noise for analysis purposes including multiple smoothing techniques are explored. We find that a Fourier filter applied at the Debye scale is an optimal choice for analyzing PIC data. Finlay, we find a broader distribution of normalized reconnection rates compared to the MHD limit with rates as large as 0.5 but with an average of approximately 0.1.

description: Recently, Zheng et al. (2005) found evidence for an overdensity of galaxies around a radio-loud quasar, SDSS J0836+0054, at z=5.8 (a five arcmin$^2$ region). We have examined our deep optical imaging data (B, V, r', i', z', and NB816) taken with the Suprime-Cam on the Subaru Telescope. The NB816 narrow-band filter (lambda_c = 815 nm and $Δλ= 12$ nm) is suitable for searching for Ly$α$ emitters at $z\approx 5.7$. We have found a new strong Ly$α$ emitter at $z \approx 5.7$ close to object B identified by Zheng et al. Further, the non detection of the nine objects selected by Zheng et al. (2005) in our B, V, and r' images provides supporting evidence that they are high-z objects.

description: We formulate world-volume actions that describe the dynamics of Dirichlet p-branes in a flat 10d background. The fields in these theories consist of the 10d superspace coordinates and an abelian world-volume gauge field. The global symmetries are given by the N=2A or N=2B super-Poincare group, according to whether p is even or odd. The local symmetries in the (p + 1)-dimensional world volume are general coordinate invariance and a fermionic kappa symmetry.

description: We reconsider the open XXZ chain of Yang and Fendley. This model possesses a lattice supersymmetry which changes the length of the chain by one site. We perform an algebraic Bethe ansatz analysis of the model and derive the commutation relations of the lattice SUSY operators with the four elements of the open-chain monodromy matrix. Hence we give the action of the SUSY operator on off-shell and on-shell Bethe states. We show that this action generally takes one on-shell Bethe eigenstate to another. The exception is that a zero-energy vacuum state will be a SUSY singlet. The SUSY pairings of Bethe roots we obtain are analogous to those found previously for closed chains by Fendley and Hagendorf by analysing the Bethe equations.

description: Mathematical models are essential tools to study how the cardiovascular system maintains homeostasis. The utility of such models is limited by the accuracy of their predictions, which can be determined by uncertainty quantification (UQ). A challenge associated with the use of UQ is that many published methods assume that the underlying model is identifiable (e.g. that a one-to-one mapping exists from the parameter space to the model output). In this study we present a novel methodology that is used here to calibrate a lumped-parameter model to left ventricular pressure and volume time series data sets. Key steps include using (1) literature and available data to determine nominal parameter values; (2) sensitivity analysis and subset selection to determine a set of identifiable parameters; (3) optimization to find a point estimate for identifiable parameters; and (4) frequentist and Bayesian UQ calculations to assess the predictive capability of the model. Our results show that it is possible to determine 5 identifiable model parameters that can be estimated to our experimental data from three rats, and that computed UQ intervals capture the measurement and model error.

description: Starting from the observation that reversible processes cannot increase the purity of any input state, we study deterministic physical processes, which map a set of states to a set of pure states. Such a process must map any state to the same pure output, if purity is demanded for the input set of all states. But otherwise, when the input set is restricted, it is possible to find non-trivial purifying processes. For the most restricted case of only two input states, we completely characterize the output of any such map. We furthermore consider maps, which combine the property of purity and reversibility on a set of states, and we derive necessary and sufficient conditions on sets, which permit such processes.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

Perturbative Dynamics of Fractional Strings on Multiply Wound D-strings

Year: 1996
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Fractional strings in the spectrum of states of open strings attached to a multiply wound D-brane is explained. We first describe the fractional string states in the low-energy effective theory where the topology of multiple winding is encoded in the gauge holonomy. The holonomy induces twisted boundary conditions responsible for the fractional moding of these states. We also describe fractional strings in world sheet formulation and compute simple scattering amplitudes for Hawking emission/absorption. Generalization to fractional DN-strings in a 1-brane 5-brane bound state is described. When a 1-brane and a 5-brane wraps $Q_1$ and $Q_5$ times respectively around a circle, the momentum of DN-strings is quantized in units of $2 π/L Q_1 Q_5$. These fractional states appear naturally in the perturbative spectrum of the theory.

description: In order to explore novel natural product-based anti-oomycete agent, ten 2-acyloxyhinokitiol derivatives (5a–j) were designed and synthesised, and structurally confirmed by 1H NMR,13C NMR, HRMS, and melting point. The stereochemical configuration of compound 5f was unambiguously confirmed by single-crystal X-ray diffraction. Furthermore, we evaluated the target compounds 5a–j as anti-oomycete activity against a serious agricultural disease of Phytophthora capsici. Among the ten hinokitiol ester derivatives tested, four compounds 5d, 5g, 5h and 5j had anti-oomycete activity higher than the positive control zoxamide (EC50 = 23.59 mg/L), and the EC50 values of 18.90, 20.62, 13.61 and 21.29 mg/L, respectively. Especially compound 5h exhibited the best anti-oomycete activity against P. capsici with EC50 value of 13.61 mg/L. Overall, the anti-oomycete activities of 2-acyloxyhinokitiol derivatives is higher than that of 2-sulfonyloxyhinokitiol derivatives. The results laid a good foundation for the subsequent synthesis of hinokitiol ester derivatives with significant anti-oomycete activity.

description: Anomaly matching constrains low-energy physics of strongly-coupled field theories, but it is not useful at finite temperature due to contamination from high-energy states. The known exception is an 't Hooft anomaly involving one-form symmetries as in pure $SU(N)$ Yang-Mills theory at $θ=π$. Recent development about large-$N$ volume independence, however, gives us a circumstantial evidence that 't Hooft anomalies can also remain under circle compactifications in some theories without one-form symmetries. We develop a systematic procedure for deriving an 't Hooft anomaly of the circle-compactified theory starting from the anomaly of the original uncompactified theory without one-form symmetries, where the twisted boundary condition for the compactified direction plays a pivotal role. As an application, we consider $\mathbb{Z}_N$-twisted $\mathbb{C}P^{N-1}$ sigma model and massless $\mathbb{Z}_N$-QCD, and compute their anomalies explicitly.

description: We consider compactifications of the N=1, d=6, E_8 theory on tori to five, four, and three dimensions and learn about some properties of this theory. As a by-product we derive the SL(2,\IZ) duality of the N=2, d=4, SU(2) theory with N_f=4. Using this theory on a D-brane probe we shed new light on the singularities of F-theory compactifications to eight dimensions. As another application we consider compactifications of F-theory, M-theory and the IIA string on (singular) Calabi-Yau spaces where our theory appears in spacetime. Our viewpoint leads to a new perspective on the nature of the singularities in the moduli space and their spacetime interpretations. In particular, we have a universal understanding of how the singularities in the classical moduli space of Calabi--Yau spaces are modified by worldsheet instantons to singularities in the moduli space of the corresponding conformal field theories.

description: While many large touchscreen devices have a split keyboard option to enable two-thumb typing, there are significant differences in the design which affect users’ text entry rate. A mixed-integer programming model is developed to optimize key-to-thumb assignment with the objective of minimizing the expected time to type a character. Computer simulations are conducted to determine the optimal key dimension under different values of the Fitts’ law’s slope coefficient, typing error rate, and alternate-hand advantage phenomenon. The results show that text entry rate and the optimal key-to-thumb assignment depend on key dimensions, user’s speed-accuracy profile, and the level of alternate-hand advantage. The optimal keyboard is proposed. To validate the analytical findings, an empirical study is conducted with eighteen users and six different keyboards in terms of key dimensions and typing zone. Empirical results report between 7% and 18% improvement in the text entry rate over the other split keyboards tested.

description: A toy model for magnetic connection in black hole (BH) accretion disc is discussed based on a poloidal magnetic field generated by a single electric current flowing around a Kerr black hole in the equatorial plane. We discuss the effects of the coexistence of two kinds of magnetic connection (MC) arising respectively from (1) the closed field lines connecting the BH horizon with the disc (henceforth MCHD), and (2) the closed field lines connecting the plunging region with the disc (henceforth MCPD). The magnetic field configuration is constrained by conservation of magnetic flux and a criterion of the screw instability of the magnetic field. Two parameters and are introduced to describe our model instead of resolving the complicated MHD equations. Compared with MCHD, energy and angular momentum of the plunging particles are extracted via MCPD more effectively, provided that the BH spin is not very high. It turns out that negative energy can be delivered to the BH by the plunging particles without violating the second law of BH thermodynamics, however it cannot be realized via MCPD in a stable way.

description: 4U0114$+$65 is one of the slowest known X-ray pulsars. We present an analysis of a pointed observation by the XMM-Newton X-ray telescope. The energy-resolved light curve, the time-resolved X-ray spectra provided by the EPIC cameras on board and the first high-resolution spectrum of this source, provided by the Reflection Grating Spectrometer, were analysed. An X-ray pulse of $9350\pm 160$ s was measured, confirming the secular spin up of this source. We also fit the pulse-phase-resolved spectra with Comptonisation models. These models imply a very small ($r\sim 3$ km) and hot ($kT\sim 2-3$ keV) emitting region and therefore point to a hot spot over the neutron star (NS) surface as the most reliable explanation for the X-ray pulse. The long NS spin period, the spin-up rate, and persistent X-ray emission can be explained within the theory of quasi-spherical settling accretion, which may indicate that the magnetic field is in the magnetar range. Thus, 4U 0114$+$65 could be a wind-accreting magnetar. We also observed two episodes of low luminosity. The first can be explained as an absorption by an over-dense structure in the wind of the donor. The second episode may be due to temporal cessation of accretion onto one magnetic pole caused by non-spherical matter capture from the structured stellar wind. The light curve displays two types of dips seen during the high-flux intervals. The short dips, with durations of tens of seconds, are produced through absorption by wind clumps. The long dips might be associated with the rarefied interclump medium. We also found evidence of emission lines in the X-ray photoionised wind of the B1Ia donor. The Fe K$α$ line is highly variable and much weaker than in other X-ray binaries with supergiant donors. The degree of wind clumping, measured through the covering fraction, is much lower than in supergiant donor stars with earlier spectral types.

description: The first investigation of the phytochemical profile of the flowers of Croton krabas led to the isolation of two new clerodane diterpenes, 6S-crotocaudin (1) and crotocaudin B (2), together with two known clerodanes, 6S-crotoeurin C (3) and isoteucvin (4). The structures and absolute configurations of isolated clerodanes were elucidated by extensive analysis of NMR spectroscopic data, mass spectrometry and ECD calculations. Compounds 1–4 demonstrated significant inhibitory activity towards acetylcholinesterase (AChE). Notably, compound 2 exhibited the strongest AChE inhibition (IC50 1.01 µM). Compounds 3 and 4 showed potent butyrylcholinesterase (BChE) inhibitory activity with IC50 values of 1.09 and 1.12 µM, respectively. The molecular docking results revealed that 2 bound to the catalytic anionic site (CAS) and peripheral anionic site (PAS) of AChE, while 3 occupied in the CAS of BChE.

description: Two new megastigmane glycosides, (6 R,7E,9R)-3-oxo-α-ionyl-9-O-α-L-rhamnopyranosyl-(1′′→4′)-β-D-glucopyranoside (1) and (6 R,7E,9R)-3-oxo-α-ionyl-9-O-β-D-glucopyranosyl-(1′′→6′)-β-D-glucopyranoside (2), together with six known analogues (3–8) were isolated from the leaves of Nicotiana tabacum. The structures of all metabolites were determined by comprehensive analysis of NMR and MS spectroscopic data as well as by comparison with those of previously reported. The in vitro anti-inflammatory activity of all isolates was evaluated using a lipopolysaccharide (LPS)-induced RAW264.7 cell inflammatory model, and the compounds 1, 3, 7, and 8 exhibited inhibition of LPS-induced NO production in RAW264.7 macrophage cells with IC50 values of 42.3-61.7 μM (positive control, dexamethasone, IC50 = 21.3 ± 1.2 μM).

description: We analyze the quark mass dependence of the Roper mass to one-loop order in relativistic baryon chiral perturbation theory. The loop integrals are evaluated using infrared regularization which preserves chiral symmetry and establishes a chiral counting scheme. The derived chiral expansion of the Roper mass may prove useful for chiral extrapolations of lattice data. For couplings of natural size the quark mass dependence of the Roper mass is similar to the one of the nucleon.

description: It was investigated the possibility of creating NbN superconducting single-photon detectors with saturated dependence of quantum efficiency versus normalized bias current. It was shown that the saturation increases for the detectors based on finer films with a lower value of Rs300/Rs20. The decreasing of Rs300/Rs20 related to increasing influence of quantum corrections to conductivity of superconductors and, in its turn, to decreasing electron diffusion coefficient. The best samples has constant value of system quantum effi-ciency 94% at Ib/Ic~0.8 and wavelength 1.31 mkm.

description: The chemical composition of the essential oil produced by hydrodistillation from the fruits of Ammodaucus leucotrichus subsp. leucotrichus Cosson & Durieu collected from southern Algeria, precisely in Aougrout District (Adrar Province), was determined by GC-MS analysis. Nineteen (19) compounds, representing 85.71% of the essential oil, were found. The essential oil contained a high percentage of perillaldehyde (80.69%). This composition is compared to numerous reported essential oils of A. leucotrichus subsp. leucotrichus fruits that are found across Algeria and Morocco in various regions. The major component perillaldehyde has drawn a lot of interest in recent years due to its notable antifungal and broader antimicrobial properties, as well as its potential advantages for human health. Thus, the studied plant represents a source of this component that should be used as food additives, perfume ingredients, and in formulations of traditional medicine.
“Here's to a Night of Drunken Mistakes”: Exploring Experiences, Regrets, and Optimism in Young Adult Drinkers

description: Background: Studies exploring “anticipated regret” concerning alcohol rarely consider the broader consequences of excessive drinking that might be regretted. Even if specific regrettable experiences are identified, interventions targeting them may not succeed because individuals are often optimistic about their risk susceptibility. Objectives: This study examined the consequences young adult drinkers reported, and the extent to which these were regretted. It then explored whether consequences and regrets differentiated between high risk, low risk and light drinkers, and whether regret was related to optimism. Methods: A cross-sectional on-line questionnaire measured drinking behavior, consequences (frequency) and regrets (extent of likely regret) and risk perceptions (in general, and compared to others). Results: 273 participants were recruited (light (30%), low-risk (40%), and high-risk drinkers (30%). PCA detected three types of experience (common—e.g., vomiting; after-effects—e.g., being depressed; and “serious”—e.g., drunk-driving), and three types of regret (“serious”—e.g., being aggressive; “common”—e.g., wasting time; and “risky behavior regrets”—e.g., drugs). Multinomial regression found the high-risk drink group more likely to be male, had more experiences but regretted these experiences less than other groups. Regrets and optimism interacted, so that higher scores on common regrets were associated with greater optimism. The high-risk group was particularly characterized by optimism. Conclusions: High-risk drinkers may be unresponsive to anticipated regret manipulations as they do not regret post-alcohol “bad” experiences, and some regrets were associated with comparative optimism. Interventions may need to focus less on regret and aim to change risk perceptions.

description: We perform quantum-correlated measurements of the decay $D \to K^{0}_{\rm S}π^{+}π^{-}π^{0}$ using a data sample corresponding to an integrated luminosity of 0.82 fb$^{-1}$ collected at the $ψ(3770)$ resonance by the CLEO-c detector. The value of the $CP$-even fraction $F_{+}$ is determined to be 0.238 $\pm$ 0.012 $\pm$ 0.012. The strong-phase differences are also measured in different regions of $K^{0}_{\rm S}π^{+}π^{-}π^{0}$ phase space by binning around the intermediate resonances present. The potential sensitivity of the results for determining the CKM angle $γ$ from $B^{\pm} \to D(K^{0}_{\rm S}π^{+}π^{-}π^{0})K^{\pm}$ decays is also discussed.
Demonstrating multipartite entanglement of single-particle W states: linear optical schemes

description: We present two linear optical schemes using nonideal photodetectors to demonstrate inseparability of W-type N-partite entangled states containing only a single photon. First, we show that the pairwise entanglement of arbitrary two modes chosen from N optical modes can be detected using the method proposed by Nha and Kim [Phys. Rev. A 74, 012317 (2006)], thereby suggesting the full inseparability among N parties. In particular, this scheme is found to succeed for any nonzero quantum efficiency of photodetectors. Second, we consider a quantum teleportation network using linear optics without auxiliary modes. The conditional teleportation can be optimized by a suitable choice of the transmittance of the beam splitter in the Bell measurement. Specifically, we identify the conditions under which maximum fidelity larger than classical bound 2/3 is achieved only in cooperation with other parties. We also investigate the case of on-off photodetectors that cannot discriminate the number of detected photons.

Statistics of the individual-pulse polarization based on propagation effects in pulsar magnetosphere
Creators: name: Petrova, S. A.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Pulsar radio emission is modelled as a sum of two completely polarized non-orthogonal modes with the randomly varying Stokes parameters and intensity ratio. The modes are the result of polarization evolution of the original natural waves in the hot magnetized weakly inhomogeneous plasma of pulsar magnetosphere. In the course of wave mode coupling, the linearly polarized natural waves acquire purely orthogonal elliptical polarizations. Further on, as the waves pass through the cyclotron resonance, they become non-orthogonal. The pulse-to-pulse fluctuations of the final polarization characteristics and the intensity ratio of the modes are attributed to the temporal fluctuations in the plasma flow. The model suggested allows to reproduce the basic features of the one-dimensional distributions of the individual-pulse polarization characteristics. Besides that, propagation origin of pulsar polarization implies a certain correlation between the mode ellipticity and position angle. On a qualitative level, for different sets of parameters, the expected correlations appear compatible with the observed ones. Further theoretical studies are necessary to establish the quantitative correspondence of the model to the observational results and to develop a technique of diagnostics of pulsar plasma on this basis.

description: Dans les confins tourmentés de la région du Kivu, les séquelles des conflits armés prolongés entravent l'accès des communautés aux services vitaux, exacerbant leur précarité existentielle. Au cœur de cette tourmente, l'emploi systématique de violences sexuelles comme stratégie de guerre a provoqué des bouleversements sociaux et territoriaux profonds, impactant de manière disproportionnée les femmes et les jeunes filles. Confrontées à des violences inimaginables, au deuil et à des traumatismes, ces dernières font face à l'isolement, à la perte de membres de leur famille et à l'interruption de l'éducation de leurs enfants, souvent recrutés de force par des factions armées.

Face à cette réalité sombre, l'intervention des organismes nationaux par le biais de soutiens financiers se révèle être une bouée de sauvetage essentielle pour les femmes et les jeunes filles affectées par les conflits dans le Sud-Kivu, en République Démocratique du Congo. Ces aides financières, bien au-delà d'un simple appui économique, jouent un rôle déterminant dans la réintégration sociale de ces femmes et jeunes filles, en leur offrant les moyens de regagner une indépendance, de subvenir à leurs besoins fondamentaux et de reconstruire leurs vies sur des fondations plus stables. Cette assistance financière est cruciale pour restaurer leur dignité, raviver l'espoir et leur permettre de prendre en charge leurs familles, contribuant ainsi significativement à la résilience et à la stabilisation de la communauté.

Ce résumé met en lumière les défis complexes auxquels sont confrontées les femmes et les jeunes filles dans la région du Kivu et souligne l'impact transformateur des aides financières. Il s'engage à démontrer comment, dans un contexte de guerre et d'après-conflit, ces soutiens ne sont pas seulement une aide économique mais un vecteur de changement social, favorisant la réintégration, la reconstruction et la résilience des individus et des communautés dévastés par les conflits.

description: Thermodynamic description of a model system with magnetoelastic coupling is presented. The elastic, vibrational, electronic and magnetic energy contributions are taken into account. The long-range RKKY interaction is considered together with the nearest-neighbour direct exchange. The generalized Gibbs potential and the set of equations of state are derived, from which all thermodynamic functions are self-consistently obtained. Thermodynamic properties are calculated numerically for FCC structure for arbitrary external pressure, magnetic field and temperature, and widely discussed. In particular, for some parameters of interaction potential and electron concentration corresponding to antiferromagnetic phase, the existence of negative thermal expansion coefficient is predicted.
