description: Healthcare as a system has been and will always be a vital public provision to support human existence. The onus rests with every nation’s healthcare system to provide health services; and individuals to consciously embrace healthy living. The health status of people in rural areas is generally not as good as those in urban areas, especially in middle and low-income countries. Research within the last decade shows significant barriers such as geographical location (terrain and transportation concerns); local health issues and availability of healthcare facilities are common concerns that affect effective delivery practices in rural settings. These barriers have affected the actualisation of a healthy environment and have regrettably led to high mortality rate from preventable and or curable causes. Consequently, in this study, findings were generated from literatures and field study and divulge that health polices, infrastructures and health service schemes are available in Bayelsa State (focus region of study), created to improve health status of the people especially those situated in the remote and riverine communities but economic, topographical and social challenges which are still prevalent have dawdled progress in attaining this goal. In response to these challenges, the study investigates and proposes strategic measures to improve the delivery practices hence, making healthcare services available and accessible to the rural poor. Therefore, the study is aimed at developing a framework for effective healthcare delivery to meet current challenges, especially where access issues are prevalent for various demographic and geographic rural settings. Review of several literatures, survey of 1637 completed questionnaire carried out between August 2016 and July 2017 within seven selected states in the Niger Delta region of Nigeria and, 13 semi - structured interviews conducted across respondents from the public and health sector within Bayelsa State, Nigeria which is the focus state for the study formed source data for evaluation. The mixed method approach was employed to evaluate existing healthcare strategies, assessment of the rural and health needs in different settings and, the required improvements to the healthcare policies. A framework which serves as strategic approach is developed and proposed for the desired improvement in the healthcare system in these rural settings following results from analysed data sets that established health and rural needs, government neglect and, accessibility issues (terrain and transportation) as the significant factors of concern.

description: The understanding of the public response to COVID-19 vaccines is the key success factor to control the COVID-19 pandemic. To understand the public response, there is a need to explore public opinion. Traditional surveys are expensive and time-consuming, address limited health topics, and obtain small-scale data. Twitter can provide a great opportunity to understand public opinion regarding COVID-19 vaccines. The current study proposes an approach using computational and human coding methods to collect and analyze a large number of tweets to provide a wider perspective on the COVID-19 vaccine. This study identifies the sentiment of tweets using a machine learning rule-based approach, discovers major topics, explores temporal trend and compares topics of negative and non-negative tweets using statistical tests, and discloses top topics of tweets having negative and non-negative sentiment. Our findings show that the negative sentiment regarding the COVID-19 vaccine had a decreasing trend between November 2020 and February 2021. We found Twitter users have discussed a wide range of topics from vaccination sites to the 2020 U.S. election between November 2020 and February 2021. The findings show that there was a significant difference between tweets having negative and non-negative sentiment regarding the weight of most topics. Our results also indicate that the negative and non-negative tweets had different topic priorities and focuses. This research illustrates that Twitter data can be used to explore public opinion regarding the COVID-19 vaccine.

description: We perform a finite-time scaling analysis over the detrapping point of a three-state quantum walk on the line. The coin operator is parameterized by $ρ$ that controls the wavepacket spreading velocity. The input state prepared at the origin is set as symmetric linear combination of two eigenstates of the coin operator with a characteristic mixing angle $θ$, one of them being the component that results in full spreading occurring at $θ_c(ρ)$ for which no fraction of the wavepacket remains trapped near the initial position. We show that relevant quantities such as the survival probability and the participation ratio assume single parameter scaling forms at the vicinity of the detrapping angle $θ_c$. In particular, we show that the participation ratio grows linearly in time with a logarithmic correction, thus shedding light on previous reports of sublinear behavior.

description: We analyze dispersion relations of magnons in ferromagnetic nanostructures with uniaxial anisotropy taking into account inertial terms, i.e. magnetic nutation. Inertial effects are parametrized by damping-independent parameter $β$, which allows for an unambiguous discrimination of inertial effects from Gilbert damping parameter $α$. The analysis of magnon dispersion relation shows its two branches are modified by the inertial effect, albeit in different ways. The upper nutation branch starts at $ω=1/ β$, the lower branch coincides with FMR in the long-wavelength limit and deviates from the zero-inertia parabolic dependence $\simeqω_{FMR}+Dk^2$ of the exchange magnon. Taking a realistic experimental geometry of magnetic thin films, nanowires and nanodiscs, magnon eigenfrequencies, eigenvectors and $Q$-factors are found to depend on the shape anisotropy. The possibility of phase-matched magneto-elastic excitation of nutation magnons is discussed and the condition was found to depend on $β$, exchange stiffness $D$ and the acoustic velocity.

description: We propose a method to compute the scattering angle for classical black hole scattering directly from two massive particle irreducible diagrams in a heavy-mass effective field theory approach to general relativity, without the need of subtracting iteration terms. The amplitudes in this effective theory are constructed using a recently proposed novel colour-kinematic/double copy for tree-level two-scalar, multi-graviton amplitudes, where the BCJ numerators are gauge invariant and local with respect to the massless gravitons. These tree amplitudes, together with graviton tree amplitudes, enter the construction of the required $D$-dimensional loop integrands and allow for a direct extraction of contributions relevant for classical physics. In particular the soft/heavy-mass expansions of full integrands is circumvented, and all iterating contributions can be dropped from the get go. We use this method to compute the scattering angle up to third post-Minkowskian order in four dimensions, including radiation reaction contributions, also providing the expression of the corresponding integrand in $D$ dimensions.

El objetivo de esta conferencia es plantear las tendencias en eLearning a tener en cuenta para la planificación, desarrollo y evaluación de una iniciativa de formación en modalidad eLearning. Para ello se va a tomar de base el lenguaje de patrón desarrollado en la tesis de Antonio Miguel Seoane Pardo (2014).

Se pone un especial énfasis en la toma de decisiones estratégicas que implica una acción formativa online, independientemente del nivel en el que se esté abordando, es decir, hay importantes decisiones que tomar en un contexto de un profesor que decide virtualizar un curso o una asignatura, o en el contexto institucional que decide hacer establecer un programa de virtualización de grados y/o másteres o lanzar una oferta de MOOC institucionales, lo cual debería estar muy ligado con la Gobernanza de las Tecnologías y de una forma más global con la estrategia de Inteligencia Institucional de la Universidad.

description: We have measured magnetoresistance of suspended graphene in the Corbino geometry at magnetic fields up to $B=0.15\,$T, i.e., in a regime uninfluenced by Shubnikov-de Haas oscillations. The low-temperature relative magnetotoresistance $[R(B)-R(0)]/R(0)$ amounts to $4000 B^2\% $ at the Dirac point ($B$ in Tesla), with a quite weak temperature dependence below $30\,$K. A decrease in the relative magnetoresistance by a factor of two is found when charge carrier density is increased to $|n| \simeq 3 \times 10^{-10}$ cm$^{-2}$. The gate dependence of the magnetoresistance allows us to characterize the role of scattering on long-range (Coulomb impurities, ripples) and short-range potential, as well as to separate the bulk resistance from the contact one. Furthermore, we find a shift in the position of the charge neutrality point with increasing magnetic field, which suggests that magnetic field changes the screening of Coulomb impurities around the Dirac point. The current noise of our device amounts to $10^{-23}$ A$^2$/$\sqrt{\textrm{Hz}}$ at $1\,$kHz at $4\,$K, which corresponds to a magnetic field sensitivity of $60$ nT/$\sqrt{\textrm{Hz}}$ in a background field of $0.15\,$T.

description: We study Fateev-Zamolodchikov-Zamolodchikov-Teschner (FZZT) branes in Witten-Kontsevich topological gravity, which includes Jackiw-Teitelboim (JT) gravity as a special case. Adding FZZT branes to topological gravity corresponds to inserting determinant operators in the dual matrix integral and amounts to a certain shift of the infinitely many couplings of topological gravity. We clarify the perturbative interpretation of adding FZZT branes in the genus expansion of topological gravity in terms of a simple boundary factor and the generalized Weil-Petersson volumes. As a concrete illustration we study JT gravity in the presence of FZZT branes and discuss its relation to the deformations of the dilaton potential that give rise to conical defects. We then construct a non-perturbative formulation of FZZT branes and derive a closed expression for the general correlation function of multiple FZZT branes and multiple macroscopic loops. As an application we study the FZZT-macroscopic loop correlators in the Airy case. We observe numerically a void in the eigenvalue density due to the eigenvalue repulsion induced by FZZT-branes and also the oscillatory behavior of the spectral form factor which is expected from the picture of eigenbranes.

description: Knowledge Distillation (KD) is a widely used technique to transfer knowledge from pre-trained teacher models to (usually more lightweight) student models. However, in certain situations, this technique is more of a curse than a blessing. For instance, KD poses a potential risk of exposing intellectual properties (IPs): even if a trained machine learning model is released in 'black boxes' (e.g., as executable software or APIs without open-sourcing code), it can still be replicated by KD through imitating input-output behaviors. To prevent this unwanted effect of KD, this paper introduces and investigates a concept called Nasty Teacher: a specially trained teacher network that yields nearly the same performance as a normal one, but would significantly degrade the performance of student models learned by imitating it. We propose a simple yet effective algorithm to build the nasty teacher, called self-undermining knowledge distillation. Specifically, we aim to maximize the difference between the output of the nasty teacher and a normal pre-trained network. Extensive experiments on several datasets demonstrate that our method is effective on both standard KD and data-free KD, providing the desirable KD-immunity to model owners for the first time. We hope our preliminary study can draw more awareness and interest in this new practical problem of both social and legal importance.

la figura e l’opera di Stefano e Luigi Gasse
Creators: name: Malangone, Marilena
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: Stefano e Luigi Gasse, figli gemelli di Stefano e Luigia Minotti, furono attivi a Napoli nella prima metà dell’Ottocento, ove lavorarono prevalentemente nella sfera dell’architettura di Stato, rendendosi interpreti delle esigenze e delle ambizioni dei ben cinque governi che, nell’arco temporale relativamente breve che li ebbe tra i principali animatori della scena architettonica partenopea, si alternarono alla guida del Regno meridionale.
La storiografia, nei circa due secoli che ci separano da essa, ha, in verità, speso molte parole in merito alla vasta produzione dei due fratelli, limitandosi, tuttavia, a valutarne prevalentemente, peraltro sempre in termini encomiastici, proprio i molti e considerevoli uffici che essi assolsero al servizio dello Stato. Diversamente, assai meno celebrate, quando non del tutto trascurate, sono state le pur numerose committenze private che i Gasse, e specialmente Stefano, onorarono, dando prova di una non minore abilità nella creazione di suggestivi brani di edilizia neoclassica e di scenografiche soluzioni paesistiche, ancor oggi distintamente riconoscibili nel confuso ed eterogeneo tessuto urbano napoletano. D’altro canto, nella considerazione dell’operato dei due professionisti, i differenti autori hanno generalmente compiuto finora indagini di tipo puntuale e per lo più mirate all’approfondimento di singoli interventi, architettonici od urbanistici, esimendosi da una ricomposizione di quei distinti episodi entro un omogeneo ed organico quadro esaustivo dell’intera loro attività, anche soltanto limitatamente ai pubblici mandati.
Ebbene, l’obiettivo che ci si è proposti nell’intraprendere il presente studio è stato, primariamente, quello di apportare un contributo alla letteratura critica ed analitica esistente sulla produzione dei gemelli Gasse, con la preparazione di un lavoro monografico che, contemplando i molteplici aspetti teorici e pratici della loro non lunghissima, ma ben prospera carriera, restituisse un prospetto agile, dettagliato e pressoché completo della vicenda di cui essi si resero protagonisti.

description: The potential energy surface (PES) of interlayer interaction of twisted bilayer graphene with vacancies in one of the layers is investigated via density functional theory (DFT) calculations with van der Waals corrections. These calculations give a non-negligible magnitude of PES corrugation of 28 meV per vacancy and barriers for relative sliding of the layers of 7 - 8 meV per vacancy for the moiré pattern with coprime indices (2,1) (twist angle 21.8$^\circ$). At the same time, using the semiempirical potential fitted to the DFT results, we confirm that twisted bilayer graphene without defects exhibits superlubricity for the same moiré pattern and the magnitude of PES corrugation for the infinite bilayer is below the calculation accuracy. Our results imply that atomic-scale defects restrict the superlubricity of 2D layers and can determine static and dynamic tribological properties of these layers in a superlubric state. We also analyze computationally cheap approaches that can be used for modeling of tribological behavior of large-scale systems with defects. The adequacy of using state-of-the-art semiempirical potentials for interlayer interaction and approximations based on the first spatial Fourier harmonics for the description of interaction between graphene layers with defects is discussed.

description: There is so much more to doing science than journal publications or grant applications, but those are the parts that often get the most attention and rewards. In this talk, I would like to discuss other forces that largely shape our research and thinking, but generally stay out of the spotlight in our field – project and people management, as perceived by a computational chemist-turned-project manager-turned-nonprofit director. Project management is becoming even more important in this era of information overload and global connectivity enabling large-scale collaborations, where clarity can quickly become an elusive and scarce resource. I will share some thoughts and lessons learned from managing my own research projects to working with a distributed team on research software development, followed by an open discussion.

description: The combination of quantum teleportation and quantum memory of photonic qubits is essential for future implementations of large-scale quantum communication and measurement-based quantum computation. Both steps have been achieved separately in many proof-of-principle experiments, but the demonstration of memory-built-in teleportation of photonic qubits remains an experimental challenge. Here, we demonstrate teleportation between photonic (flying) and atomic (stationary) qubits. In our experiment, an unknown polarization state of a single photon is teleported over 7 m onto a remote atomic qubit that also serves as a quantum memory. The teleported state can be stored and successfully read out for up to 8 micro-second. Besides being of fundamental interest, teleportation between photonic and atomic qubits with the direct inclusion of a readable quantum memory represents a step towards an efficient and scalable quantum network.

Rheology of viscoelastic suspensions

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: The rheology of suspensions of solid particles in viscoelastic fluids is important in many technological applications as exemplified by the processing of
filled polymers e.g. injection molding, coating processes, application in food and health care products,...
Consequently, considerable attention in the literature is given to the rheology of suspensions of particles. Most studies are focused on highly filled systems (typically, volume fractions greater than 10%), with polydisperse particles of irregular shapes due to their technological importance. In contrast, realtively few studies are conducted on the rheology of dilute or semi-dilute suspensions of monodisperse spheres.
In the first part we elucidate the effect of viscoelasticity on the bulk rheological properties. The behavior of model suspensions composed of non
Brownian, inertialess, rigid spheres immersed in Newtonian and viscoelastic matrices is investigated in the concentration range from 0 up to 10%, thus
encompassing both the dilute and semidilute regimes. The data are fitted with quadratic polynomial functions of the particle volume fraction in order to compare with theoretical, empirical and experimental models.
As second part, new simulation technique for suspensions in Newtonian fluids under oscillatory shear flow is presented. The cases of a single sphere and two particles are studied and discussed. Finally, the flow induced microstructure of suspensions in viscoelastic fluids is studied by rheo-optical techniques. More specifically, the flow-induced alignment of non-colloidal particles in viscoelastic fluids is investigated systematically in an attempt to quantify the alignment of the particles and
correlate it with the shear rate, size of the particles and interactions with the wall.

description: When a computational system continuously learns from an ever-changing environment, it rapidly forgets its past experiences. This phenomenon is called catastrophic forgetting. While a line of studies has been proposed with respect to avoiding catastrophic forgetting, most of the methods are based on intuitive insights into the phenomenon, and their performances have been evaluated by numerical experiments using benchmark datasets. Therefore, in this study, we provide the theoretical framework for analyzing catastrophic forgetting by using teacher-student learning. Teacher-student learning is a framework in which we introduce two neural networks: one neural network is a target function in supervised learning, and the other is a learning neural network. To analyze continual learning in the teacher-student framework, we introduce the similarity of the input distribution and the input-output relationship of the target functions as the similarity of tasks. In this theoretical framework, we also provide a qualitative understanding of how a single-layer linear learning neural network forgets tasks. Based on the analysis, we find that the network can avoid catastrophic forgetting when the similarity among input distributions is small and that of the input-output relationship of the target functions is large. The analysis also suggests that a system often exhibits a characteristic phenomenon called overshoot, which means that even if the learning network has once undergone catastrophic forgetting, it is possible that the network may perform reasonably well after further learning of the current task.

description: In this paper, we analyse the causal aspects of evolving marginally trapped surfaces in a D-dimensional spherically symmetric spacetime, sourced by perfect fluid with a cosmological constant. The norm of the normal to the marginally trapped tube is shown to be the product of lie derivatives of the expansion parameter of future outgoing null rays along the incoming and outgoing null directions. We obtain a closed form expression for this norm in terms of principal density, pressure, areal radius and cosmological constant. For the case of a homogeneous fluid distribution, we obtain a simple formula for determining the causal nature of the evolving horizons. We obtain the causal phase portraits and highlight the critical radius. We identify many solutions where the causal signature of the marginally trapped tube or marginally anti-trapped tube is always null despite having an evolving area. These solutions don't comply with the standard inner and outer horizon classification for degenerate horizons. we propose an alternate prescription for this classification of these degenerate horizons.

The removal of shear-ellipticity correlations from the cosmic shear signal via nulling techniques

Publisher: name: arXiv

description: To render cosmic shear an astronomical tool of high precision, it is essential to eliminate systematic effects upon its signal, one of the most significant ones being correlations between the gravitational shear and the intrinsic ellipticity of source galaxies. Because of the crudeness of current models of intrinsic alignment, we have developed a model-independent, purely geometrical method to remove shear-ellipticity correlations. We eliminate the contributions to a tomographic cosmic shear signal that may be subject to contamination by shear-ellipticity correlations, making use of the characteristic dependence of these correlations on redshift. By introducing an appropriately chosen weight function to the lensing efficiency that nulls signals stemming from certain distances, new second-order measures of cosmic shear, free of intrinsic alignment, can be constructed. The loss of information induced by this nulling technique and the subsequent degradation of constraints on cosmological parameters is quantified in a likelihood analysis. Concerning the construction of optimal weight functions, good agreement is achieved between all approaches considered. For a survey divided into 20 redshift bins we find that the area of credible regions increases by 20% up to about 50% after the application of nulling, depending on the cosmological parameters considered. We demonstrate that due to an optimization of the weight functions nearly all information is contained in a small subset of the new second-order measures. The use of a significantly smaller number of redshift bins than 20 for the nulling considerably degrades parameter constraints under conservative assumptions, emphasizing the need for detailed redshift information.

The problem of estimating the number of regimes in this type of series is that of determining the number of states in the hidden Markov chain controlling the process. We propose a method based on penalized maximum likelihood estimation and establish its strong consistency (almost sure) without assuming previous bounds on the number of states.

description: We present a classical approach of a mixture of compressible fluids when each constituent has its own temperature. The introduction of an average temperature together with the entropy principle dictates the classical Fick law for diffusion and also novel constitutive equations associated with the difference of temperatures between the components. The constitutive equations fit with results recently obtained through Maxwellian iteration procedure in extended thermodynamics theory of multitemperature mixtures. The differences of temperatures between the constituents imply the existence of a new dynamical pressure even if the fluids have a zero bulk viscosity. The nonequilibrium dynamical pressure can be measured and may be convenient in several physical situations as for example in cosmological circumstances where - as many authors assert - a dynamical pressure played a major role in the evolution of the early universe.

description: Curcuminoids are dietary complexes extracted from the seeds of Curcuma longa L. that contain curcumin, bisdemethoxycurcumin and desmethoxycurcumin. Curcuminoids are popular for their pleiotropic therapeutic functions, such as their anti-inflammatory and anti-oxidant effects. Nonetheless, their clinical use is associated with poor systemic bioavailability and insolubility. The nano-formulation of curcuminoids eliminates these shortcomings. In the present study, we explored immunoregulatory, proliferative and anti-oxidant effects of nanocurcuminoids on adipose-derived mesenchymal stem cells (AT-MSCs). Flow cytometry analysis and MTT assay were employed to explore the effects of nanocurcuminoids on the apoptosis and proliferation of adipose-derived MSCs (AT-MSCs). The anti-oxidant effect of nanocurcuminoids on AT-MSCs also was examined. The immune regulatory effect of nanocurcuminoids was evaluated by the flow cytometric measurement of the T regulatory (Treg) population. The expression of inflammatory and anti-inflammatory cytokines was quantified using real-time PCR.  Our findings demonstrate that low concentrations of nanocurcuminoids are beneficial for MSC proliferation, protection of MSCs from apoptosis, reducing inflammatory cytokines and SOD activity. A high concentration of nanocurcuminoids increases the population of Tregs and elevates the expression of TGFβ and FOXP3 genes. The beneficial effects of nanocurcuminoids on AT-MSCs were mainly observed at low doses of nanocurcuminoids.

description: We present a method of transferring a cold atom between spatially separated microtraps by means of a Raman transition between the ground motional states of the two traps. The intermediate states for the Raman transition are the vibrational levels of a third microtrap, and we determine the experimental conditions for which the overlap of the wave functions leads to an efficient transfer. There is a close analogy with the Franck-Condon principle in the spectroscopy of molecules. Spin-dependent manipulation of neutral atoms in microtraps has important applications in quantum information processing. We also show that starting with several atoms, precisely one atom can be transferred to the final potential well hence giving deterministic preparation of single atoms.

description: Dans les années qui précèdent le ministère de Turgot et la suppression des corporations dans tout le royaume (1776), un large mouvement de réforme est déjà à l'étude au sein du Conseil du roi. Les derniers moments du règne de Louis XV voient déjà la fin des oppositions parlementaires grâce à la révocation des charges des plus hauts magistrats (réforme de Maupeou, 1771-1774), et ce moment d'autoritarisme royal déborde largement du cadre de la justice. Tout l'ordre corporatif est alors pris à parti, par plusieurs projets de refonte générale des statuts et une mise sous tutelle des métiers, dont tous les actes publics seraient placés sous le contrôle des officiers de police locaux (validation des apprentissages, réception des nouveaux maîtres, postes de dépenses communes...). Dépossédés de la gestion de leur finance, les métiers verraient leur bduget définitivement intégrée à l'appareil fiscal monarchique.
Prenant la forme d'édits, qui n'attendent que leur émission et leur enregistrement, ces projets sont toutefois connus des principales corporations, dont les Six Corps des marchands de Paris qui y répondent avec circonspection, dans un rapport de force politique qu'ils ne dominent plus, voire dans une adhésion à plusieurs aspects des projets. Ainsi, le programme de libéralisation du commerce qui a débuté dès les années 1750, s'accompagne d'un fort volet autoritaire et dirigiste des cadres corporatifs, qui en montrent toute l'ambivalence.

description: In recent years, there has been a growing interest in multiple access communication systems that spread their transmitted energy over very large bandwidths. These systems, which are referred to as ultra wide-band (UWB) systems, have various advantages over narrow-band and conventional wide-band systems. The importance of multiuser detection for achieving high data or low bit error rates in these systems has already been established in several studies. This paper presents iterative ('turbo') multiuser detection for impulse radio (IR) UWB systems over multipath channels. While this approach is demonstrated for UWB signals, it can also be used in other systems that use similar types of signaling. When applied to the type of signals used by UWB systems, the complexity of the proposed detector can be quite low. Also, two very low complexity implementations of the iterative multiuser detection scheme are proposed based on Gaussian approximation and soft interference cancellation. The performance of these detectors is assessed using simulations that demonstrate their favorable properties.

description: Strong correlation effects in a capacitively coupled double quantum-dot setup were previously shown to provide the possibility of both entangling spin-charge degrees of freedom and realizing efficient spin-filtering operations by static gate-voltage manipulations. Motivated by the use of such a device for quantum computing, we study the influence of electromagnetic noise on a general spin-orbital Kondo model, and investigate the conditions for observing coherent, unitary transport, crucial to warrant efficient spin manipulations. We find a rich phase diagram, where low-energy properties sensitively depend on the impedance of the external environment and geometric parameters of the system. Relevant energy scales related to the Kondo temperature are also computed in a renormalization-group treatment, allowing to assess the robustness of the device against environmental effects.

Mass transfer from a giant star to a main sequence companion and its contribution to long-orbital-period blue stragglers

description: Binary population synthesis shows that mass transfer from a giant star to a main-sequence (MS) companion may account for some observed long-orbital period blue stragglers. However, little attention {\bf is paid to this blue straggler formation scenario} as dynamical instability often happens when the mass donor is a giant star. In this paper, we have studied the critical mass ratio, $q_{\rm c}$, for dynamically stable mass transfer from a giant star to a MS companion using detailed evolution calculations. The results show that a more evolved star is generally less stable for Roche lobe overflow. Meanwhile, $q_{\rm c}$ almost linearly increases with the amount of the mass and angular momentum {\bf lost} during mass transfer, but has little dependance on stellar wind. To conveniently use the result, we give a fit of $q_{\rm c}$ as a function of the stellar radius at the onset of Roche lobe overflow and of the mass transfer efficiency during the Roche lobe overflow. To examine the formation of blue stragglers from mass transfer between giants and MS stars, we have performed Monte Carlo simulations with various $q_{\rm c}$. {\bf The simulations show that some binaries with the mass donor on the first giant branch may contribute to blue stragglers with $q_{\rm c}$ obtained in this paper but will not from previous $q_{\rm c}$. Meanwhile, from our $q_{\rm c}$, blue stragglers from the mass transfer between an AGB star and a MS companion may be more numerous and have a wider range of orbital periods than those from the other $q_{\rm c}$.

STEREO PIV ANALYSIS AND APPLICATION TO CYLINDER WAKE

description: A theoretical analysis of the spatial resolution of the Stereo Particle Image Velocimetry (PIV) technique has been performed. This has been done in terms of Modulation Transfer Function (MTF) and by applying the technique with and without the correction of the misalignment error between calibration and measurement planes. The results show that some wavelengths of the flow field can be significantly dephased and modulated. The theoretical analysis has been extended to investigate also the effects caused by the laser thickness and the linear dimension of the interrogation window W (i.e. the modulation associated to the Stereo PIV process). As it will be shown in detail in this work, the modulation associated to the last two parameters cannot be corrected, differently from the modulation due to the misalignment. A performance assessment has been conducted with both synthetic and real images and shows a good agreement with the theoretical analysis.
The reconstruction of the three-dimensional displacement field is achieved using both methods proposed by Soloff et al. (1997) and by Willert (1997).
Finally, the Stereo PIV technique has been used to analyse the vortex shedding caused by both finite and infinite cylinders immersed in a uniform flow field. The Reynolds numbers investigated are within the Shear-Layer Transition Regime, indicated by Williamson (1996) for the infinite cylinder. This regime is characterized by the formation of von Kàrmàn vortices. For the finite cylinder, a counter-rotating pair of tip vortices forms at the free end, extends into the wake and interacts in a complex manner with the von Kàrmàn vortex shedding.
To detect the von Kàrmàn vortex shedding a phase averaged method has been chosen. This approach uses the Proper Orthogonal Decomposition (POD) technique and it has been evidenced that it works properly for the infinite cylinder and for some sections near the base of the finite one.
