description: The electric conductance of a strip of undoped graphene increases in the presence of a disorder potential, which is smooth on atomic scales. The phenomenon is attributed to impurity-assisted resonant tunneling of massless Dirac fermions. Employing the transfer matrix approach we demonstrate the resonant character of the conductivity enhancement in the presence of a single impurity. We also calculate the two-terminal conductivity for the model with one-dimensional fluctuations of disorder potential by a mapping onto a problem of Anderson localization.

description: A few 85Rb atoms were trapped in a micron-size magneto-optical trap with a high quadrupole magnetic-field gradient and the number of atoms was precisely controlled by suppressing stochastic loading and loss events via real-time feedback on the magnetic field gradient. The measured occupation probability of single atom was as high as 99%. Atoms up to five were also trapped with high occupation probabilities. The present technique could be used to make a deterministic atom source.

description: Recent theoretical work has shown that the competition between coherent unitary dynamics and stochastic measurements, performed by the environment, along wavefunction trajectories can give rise to transitions in the entanglement scaling. In this work, complementary to these previous studies, we analyze a situation where the role of Hamiltonian and dissipative dynamics is reversed. We consider an engineered dissipation, which stabilizes an entangled phase of a quantum spin$-1/2$ chain, while competing single-particle or interacting Hamiltonian dynamics induce a disentangled phase. Focusing on the single-particle unitary dynamics, we find that the system undergoes an entanglement transition from a logarithmic growth to an area law when the competition ratio between the unitary evolution and the non-unitary dynamics increases. We evidence that the transition manifests itself in state-dependent observables at a finite competition ratio for Hamiltonian and measurement dynamics. On the other hand, it is absent in trajectory-averaged steady-state dynamics, governed by a Lindblad master equation: although purely dissipative dynamics stabilizes an entangled state, for any non-vanishing Hamiltonian contribution the system ends up irremediably in a disordered phase. In addition, a single trajectory analysis reveals that the distribution of the entanglement entropy constitutes an efficient indicator of the transition. Complementarily, we explore the competition of the dissipation with coherent dynamics generated by an interacting Hamiltonian, and demonstrate that the entanglement transition also occurs in this second model. Our results suggest that this type of transition takes place for a broader class of Hamiltonians, underlining its robustness in monitored open quantum many-body systems.

description: We present high resolution 0.45" x 0.32" observations from the BIMA array toward the Herbig Ae system MWC 480 in the lambda = 1.4 mm dust continuum. We resolve a circumstellar disk of radius ~170 AU and constrain the disk parameters by comparing the observations to flat disk models. These results show that the typical fit parameters of the disk, such as the mass, Md ~ 0.04-0.18 Mo, and the surface density power law index, p=0.5 or 1, are comparable to those of the lower mass T Tauri stars. The dust in the MWC 480 disk can be modeled as processed dust material (beta ~ 0.8), similar to the Herbig Ae star CQ Tau disk; the fitted disk parameters are also consistent with less-evolved dust (beta ~ 1.2). The possibility of grain growth in the MWC 480 circumstellar disk is supported by the acceptable fits with beta ~ 0.8. The surface density power-law profiles of p=0.5 and p=1 can be easily fit to the MWC 480 disk; however, a surface density power-law profile similiar to the minimum mass solar nebula model p=1.5 is ruled out at an 80% confidence level.

description: The advent of the 5G era means that the concepts of robot, VR/AR, UAV, smart home, smart healthcare based on IoT (Internet of Things) have gradually entered human life. Since then, intelligent life has become the dominant direction of social development. Humidity sensors, as humidity detection tools, not only convey the comfort of human living environment, but also display great significance in the fields of meteorology, medicine, agriculture and industry. Graphene-based materials exhibit tremendous potential in humidity sensing owing to their ultra-high specific surface area and excellent electron mobility under room temperature for application in humidity sensing. This review begins with the introduction of examples of various synthesis strategies of graphene, followed by the device structure and working mechanism of graphene-based humidity sensor. In addition, several different structural design methods of graphene are summarized, demonstrating the structural design of graphene can not only optimize the performance of graphene, but also bring significant advantages in humidity sensing. Finally, key challenges hindering the further development and practical application of high-performance graphene-based humidity sensors are discussed, followed by presenting the future perspectives.

Superior material characteristics, rendering Li(Zn,Mn)As a realistic candidate for such a system, include unlimited solubility of the isovalent substitutional Mn impurity and carrier concentration controlled independently of Mn doping by adjusting Li-(Zn,Mn) stoichiometry. Our predictions are anchored by detail ab initio calculations and comparisons with the familiar and directly related (Ga,Mn)As, by the microscopic physical picture we provide for the exchange interaction between Mn local moments and electrons in the conduction band, and by analysis of prospects for the controlled growth of Li(Zn,Mn)As materials.

description: In recent years, pressure sensors have been widely used as crucial technology components in industrial, healthcare, consumer electronics, and automotive safety applications. With the development of intelligent technologies, there is a growing demand for pressure sensors with higher sensitivity, smaller size, and wider detection range. Graphene and its derivatives, as novel emerging materials in recent years, have received widespread attention from researchers due to their unique mechanical and electrical properties, and are considered as promising sensing materials for the high-performance pressure sensors. In general, graphene-based pressure sensors can be classified into flexible pressure sensors and gas pressure sensors. In this paper, we firstly introduce the basic properties of graphene and its derivatives and then review the research progress of both graphene-based flexible pressure sensors and graphene-based gas pressure sensors respectively, focusing on different sensing mechanisms. Finally, the application prospects of graphene-based pressure sensors as well as future challenges are discussed.

Year: 2008

description: The purpose of this phenomenological study was to determine the meaning mothers give to their family's experience when caring for their child at home following an acute surgical procedure. The information gained will provide direction for nurses who prepare parents to care for their child at home after discharge from hospital. A purposive sample of eight primary care-givers, all mothers, were interviewed for data collection. A total of 21 interviews were conducted. The children were from 7months to 14 years of age, all from dual parent families. A semi-structured guide of open-ended questions was used for the interviews. Analysis of the verbatim transcriptions began concurrently with data collection and continued during the formal analytic phase. The mothers' experiences were closely linked to a series of events beginning when the child became ill and ending when the family's activities were back to normal. The mothers' accounts were synthesized into a descriptive framework of their experiences which described three chronological phases: (1) the onset of symptoms leading to help seeking and hospitalization, (2) the hospitalization, treatment, and preparation for discharge, and (3) the care of the child at home and getting back to normal. The study's findings revealed that mothers perceived their experience as disruptive for themselves and for family life. The mothers described how uncertain they felt especially concerning the child's diagnosis, surgery, and after discharge. Related feelings of worry, anxiety, and stress were reported in varying degrees of intensity throughout their experience. New responsibilities were added to their lives and they became exhausted. The mothers used a range of coping strategies to manage the child's care as well as their own feelings. The study findings were compared to related literature for discussion. General implications for nursing practice, education, and research were presented.

Through planar algebra techniques, we demonstrate the existence of a finite index singular subfactor of the hyperfinite \IIi factor that cannot be strongly singular with $α=1$, in contrast to the case for masas. Using work of Popa, Sinclair, and Smith, we show that there exists an absolute constant $0

Using 425 pb^{-1} of data collected using the D0 detector at the Fermilab Tevatron Collider, and enhancing the ttbar content of the sample by tagging b jets with a secondary vertex tagging algorithm, the ttbar production cross section is measured to be: 6.6 \pm 0.9 (stat+syst) \pm 0.4 (lum) pb. This cross section is the most precise D0 measurement to date for ttbar production and is in good agreement with standard model expectations.

description: Pluto's atmospheric profiles (temperature and pressure) have been studied for decades from stellar occultation lightcurves. In this paper, we look at recent Pluto Global Climate Model (GCM) results (3D temperature, pressure, and density fields) from Bertrand et al. (2020) and use the results to generate model observer's plane intensity fields (OPIF) and lightcurves by using a Fourier optics scheme to model light passing through Pluto's atmosphere (Young, 2012). This approach can accommodate arbitrary atmospheric structures and 3D distributions of haze. We compared the GCM model lightcurves with the lightcurves observed during the 15-AUG-2018 Pluto stellar occultation. We find that the climate scenario which best reproduces the observed data includes an N2 ice mid-latitude band in the southern hemisphere. We have also studied different haze and P/T ratio profiles: the haze effectively reduces the central flash strength, and a lower P/T ratio both reduces the central flash strength and incurs anomalies in the shoulders of the central flash.

description: Capacitive touch sensors capture the two-dimensional spatial profile (referred to as a touch heatmap) of a finger's contact with a mobile touchscreen. However, the research and design of touchscreen mobile keyboards -- one of the most speed and accuracy demanding touch interfaces -- has focused on the location of the touch centroid derived from the touch image heatmap as the input, discarding the rest of the raw spatial signals. In this paper, we investigate whether touch heatmaps can be leveraged to further improve the tap decoding accuracy for mobile touchscreen keyboards. Specifically, we developed and evaluated machine-learning models that interpret user taps by using the centroids and/or the heatmaps as their input and studied the contribution of the heatmaps to model performance. The results show that adding the heatmap into the input feature set led to 21.4% relative reduction of character error rates on average, compared to using the centroid alone. Furthermore, we conducted a live user study with the centroid-based and heatmap-based decoders built into Pixel 6 Pro devices and observed lower error rate, faster typing speed, and higher self-reported satisfaction score based on the heatmap-based decoder than the centroid-based decoder. These findings underline the promise of utilizing touch heatmaps for improving typing experience in mobile keyboards.

description: The subject of our thesis is a comparative analysis of two books concerning historical memoirs of the 19th century from Greece and Italy respectively. The books are Historical memories(1874) by Nicolaos Dragoumis and Memories of Italy and especially of Tuscany from 1814 to 1850(1853) by Giuseppe Montanelli. In the introductory chapter the literary genre called memoirs is described, its relevance with similar genre such as autobiography and the most important books on memoirs of both countries are presented. In the first part the book of Dragoumis is analysed : how the writer narrates the events to 1862 when the reign of king Othon came to a sudden end, and his activity as a scholer. Then the book of Montanelli is analysed in a similar way with emphasis on the efforts to unify Italy and thus in the institution of National Assembly promoted by the Italian author and politician. In the last chapter a description of the structure of the 2 books is done and comparative remarks are made

Comparison of intramuscular absorption above and below the level of a spinal cord injury
Creators: name: Spurrell, Valerie Jean
Publisher: name: University of British Columbia
Year: 2008

description: This study was designed to determine the difference in drug absorption between intramuscular injections given above and below the lesion in persons with a spinal cord injury. The theoretical framework identified three categories of factors known to influence serum drug absorption following intramuscular injections: drug action, diffusion area, and blood flow, with a focus on muscle innervation as one factor in the blood flow category. Hypotheses tested in this study were that serum trough and serum peak levels are greater and absorption time is shorter when I.M. injections of gentamicin are given above the level of a spinal cord injury than when given below. The study used an experimental, repeated measures design with counterbalancing and subjects acted as their own controls by receiving injections both above and below the level of injury. A total of five serum samples were drawn before and after a series of injections in each site to determine any differences in serum drug absorption. When it was not possible to obtain the sample size intended, case analysis was used to study the three subjects who enrolled in the study. Factors which may have influenced the difficulty in obtaining a larger sample are identified and discussed. The results of the study indicated that of the three cases, only in the first case were the serum trough and peak levels higher following deltoid injections than following gluteal injections. The contrary results for the second and third case may have been related to differences in the number of injections and differences in the dosing intervals. The time between serum samples was too great to accurately differentiate the absorption times, but pharmacokinetic values associated with the elimination phase suggested that absorption was delayed following injections below the level of injury. In all three cases the elimination rate constant was smaller, the half-life longer, and the volume of distribution larger following injections below the level of injury. In addition, the logarithmic plotting of serum levels following injections in paralyzed muscle was non-linear, adding further support to the supposition that absorption was delayed. With a sample size of three, conclusions are tentative. The findings suggest that peak and trough serum levels may be greater following injections above the level of injury as compared to below if the dosing interval is every 12 hours and steady state is achieved prior to serum samples being drawn. Given possible delayed absorption from paralyzed muscle, shortened dosing intervals may result in drug accumulation. The results of this study have implications for practice related to I.M. site selection, dosing levels, and serum levels. Education for health professionals must address innervation as a possible influence on I.M. drug absorption. This study provides insight into areas for further refinement of the theoretical framework as well as areas for further research.

description: We prove that every metric graph which is a tree has an orthonormal sequence of Laplace-eigenfunctions of full support. This implies that the number of nodal domains $ν_n$ of the $n$-th eigenfunction of the Laplacian with standard conditions satisfies $ν_n/n \to 1$ along a subsequence and has previously only been known in special cases such as mutually rationally dependent or rationally independent side lengths. It shows in particular that the Pleijel nodal domain asymptotics from two- or higher dimensional domains cannot occur on these graphs: Despite their more complicated topology, they still behave as in the one-dimensional case. We prove an analogous result on general metric graphs under the condition that they have at least one Dirichlet vertex. Furthermore, we generalize our results to Delta vertex conditions and to edgewise constant potentials. The main technical contribution is a new expression for a secular function in which modifications to the graph, to vertex conditions, and to the potential are particularly easy to understand.

description: Visual search plays an essential role for E-commerce. To meet the search demands of users and promote shopping experience at Alibaba, visual search relevance of real-shot images is becoming the bottleneck. Traditional visual search paradigm is usually based upon supervised learning with labeled data. However, large-scale categorical labels are required with expensive human annotations, which limits its applicability and also usually fails in distinguishing the real-shot images. In this paper, we propose to discover Virtual ID from user click behavior to improve visual search relevance at Alibaba. As a totally click-data driven approach, we collect various types of click data for training deep networks without any human annotations at all. In particular, Virtual ID are learned as classification supervision with co-click embedding, which explores image relationship from user co-click behaviors to guide category prediction and feature learning. Concretely, we deploy Virtual ID Category Network by integrating first-clicks and switch-clicks as regularizer. Incorporating triplets and list constraints, Virtual ID Feature Network is trained in a joint classification and ranking manner. Benefiting from exploration of user click data, our networks are more effective to encode richer supervision and better distinguish real-shot images in terms of category and feature. To validate our method for visual search relevance, we conduct an extensive set of offline and online experiments on the collected real-shot images. We consistently achieve better experimental results across all components, compared with alternative and state-of-the-art methods.

Τα δείγματα προέρχονταν από τη στοματική και φαρυγγική κοιλότητα, τις ρινικές κοιλότητες, την τραχεία, τους πνεύμονες, την καρδιά, το ήπαρ, τους νεφρούς, το σπλήνα, το γαστρεντερικό σύστημα και τη μήτρα, πραγματοποιήθηκαν βακτηριολογικές, παρασιτολογικές και ορολογικές εξετάσεις. Από τα αποτελέσματα προέκυψε ότι το σύνολο των ζώων ήταν μολυσμένα με τουλάχιστον ένα βακτήριο ή παράσιτο. Τα αποτελέσματα της έρευνας μας οδήγησαν στη διαπίστωση ότι από τις υπάρχουσες εκτροφές είναι παρακινδυνευμένο να γίνεται προμήθεια ζώων για πειραματικούς σκοπούς, ενώ πρέπει να δημιουργηθούν εξειδικευμένες εκτροφές προμήθειας κουνελιών πειραματόζωων
description: The aim of the present study was to investigate the health status of the rabbits that are also used as laboratory animals in our country. Animals from 4 breeding units that supplied lab rabbits were examined. In total 69 rabbits of both sexes were examined. Specimens from the month and rharynx, trachea, lungs, heart, liver, kidneys, spleen, gastrointestinal organs and utepus were examined microbiologically and paasitologivally. Serological examinations were also performed. The results of the study showed that all the animals were infected with at least one bacterium or parasite. We conclude that lab animals should not be provided from such units and that specialized units must be created in our country

description: Η διατριβή μου εξετάζει "Το ταξίδι των αθώων" του Τουέϊν, "Την αμερικανική σκηνή" του Τζέϊμς και τα έργα της Βακά Μπράουν "Η καρδιά των Βαλκανίων", "Στην καρδιά της Γερμανικής Ιντριγκας", "Ενα παιδί της ανατολής", και με την "Καρδιά για κάθε πίστη/μοίρα" μέσα στο θεωρητικό πλαίσιο της πολιτισμικής γεωγραφίας και αναλύει την ποιητική του χώρου και την πολιτική της ταυτότητας όπως αυτές προβάλλονται στο έργο των 3 συγγραφέων. Οπως αποδεικνύω, τα υπό συζήτηση έργα σηματοδοτούν μία πρόοδο στον τρόπο με τον οποίο ο πρώϊμος αμερικανικός μοντερνισμός χειρίστηκε τα αλληλένδετα ερωτήματα του χώρου και της διαμόρφωσης πολιτισμικών ταυτοτήτων. Ο λόγος για τον οποίο επέλεξα τα συγκεκριμένα κείμενα είναι για να σκιαγραφήσω πως οι 3 συγγραφείς διαφοροποιούνται σε σχέση με τον τρόπο που ο αφηγηματικός τους λόγος αναπαριστά τη σχέση ατόμου-χώρου. Τα επιμέρους κεφάλαια αναδεικνύουν την πορεία μέσα από την οποία διαμορφώνεται η αφηγηματική ταυτότητα σαν μια διαδικασία συνυφασμένη με τις ιστορικές εξελίξεις της εποχής, αλλά και το χωροταξικό και κοινωνικό πλαίσιο. Κατά τη γνώμη μου, η ρητορική του χώρου που υιοθέτησαν οι 3 συγγραφείς έχει κοινά στοιχεία και αποδεικνύει ότι η αφηγηματική οπτική των έργων τους αντανακλά τον τρόπο με τον οποίο ο καθένας τους ξεχωριστά βίωσε την εμπειρία της νεωτερικότητας. Συνοψίζοντας, καταλήγω στο ότι οι έννοιες του χώρου, της γεωγραφίας και της ταυτότητας απασχόλησαν άμεσα τους 3 συγγραφείς οι οποίοι αποτύπωσαν το πέρασμα από το ρεαλισμό στο μοντερνισμό μέσα στα πλαίσια της ταξιδιωτικής γραμματείας
description: My dissertation places Twain's The innocents abroad, James's The american scene, and Vaka Brown's The heart of the Balkans, In the heart of german intrigue, A child of the orient and with a heart for any faith/fate in a cultural geographical context and discusses the three authors' spatial poetics and identity politics. I assert that the texts in question trace a development in literary responses to the question of spatiality and the interrelated concept of identity formation, within the frame of early modernist American literature. I examine these texts for the different theories of human-place relations that are inherent in their narrative discourses. The individual chapters examine the construction of narrative identity as a project that is historically contirgent, but also spatially, socially and culturally significant. In my view, the three authors' interlocking spatial discourses reveal their narrative perspectives as manifestations of thei individual responses to modernity. I conclude that space, geography and identity prove active and pervasive interests for three authors two trace the more from the realist to the modernist tradition of travel literature

description: We present c2d Spitzer/IRAC observations of the Lupus I, III and IV dark clouds and discuss them in combination with optical and near-infrared and c2d MIPS data. With the Spitzer data, the new sample contains 159 stars, 4 times larger than the previous one. It is dominated by low- and very-low mass stars and it is complete down to M $\approx$ 0.1M$_\odot$. We find 30-40 % binaries with separations between 100 to 2000 AU with no apparent effect in the disk properties of the members. A large majority of the objects are Class II or Class III objects, with only 20 (12%) of Class I or Flat spectrum sources. The disk sample is complete down to ``debris''-like systems in stars as small as M $\approx$ 0.2 M$_\odot$ and includes sub-stellar objects with larger IR excesses. The disk fraction in Lupus is 70 -- 80%, consistent with an age of 1 -- 2 Myr. However, the young population contains 20% optically thick accretion disks and 40% relatively less flared disks. A growing variety of inner disk structures is found for larger inner disk clearings for equal disk masses. Lupus III is the most centrally populated and rich, followed by Lupus I with a filamentary structure and by Lupus IV, where a very high density core with little star-formation activity has been found. We estimate star formation rates in Lupus of 2 -- 10 M$_\odot$ Myr$^{-1}$ and star formation efficiencies of a few percent, apparently correlated with the associated cloud masses.

Neutrinos as cluster dark matter

description: The dynamical mass of clusters of galaxies, calculated in terms of modified Newtonian dynamics, is a factor of two or three times smaller than the Newtonian dynamical mass but remains significantly larger than the observed baryonic mass in the form of hot gas and stars in galaxies. Here I consider further the suggestion that the undetected matter might be in the form of cosmological neutrinos with mass on the order of 2 eV. If the neutrinos and baryons have comparable velocity dispersions and if the two components maintain their cosmological density ratio, then the electron density in the cores of clusters should be proportional to temperature to the 3/2 power, as appears to be true in non-cooling flow clusters. This is equivalent to the ``entropy floor'' proposed to explain the steepness of the observed luminosity-temperature relation, but here preheating of the medium is not required. Two fluid (neutrino-baryon) hydrostatic models of clusters, in the context of MOND, reproduce the observed luminosity-temperature relation of clusters. If the beta law is imposed the gas density distribution, then the self-consistent models predict the general form of the observed temperature profile in both cooling and non-cooling flow clusters.

description: The measurement of the so far unknown chiral-odd quark transverse spin distribution in either semi-inclusive DIS (SIDIS) or inclusive measurements in pp collisions at RHIC has an additional chiral-odd fragmentation function appearing in the cross section. These chiral-odd fragmentation functions (FF) can for example be the so-called Collins FF or the Interference FF. HERMES has given a first hint that these FFs are nonzero, however in order to measure the transversity one needs these FFs to be precisely known. We have used 29.0 fb$^{-1}$ of data collected by the Belle experiment at the KEKB $e^+e^-$ collider to measure azimuthal asymmetries for different charge combinations of pion pairs and thus access the Collins FF.

description: Since the introduction of the radio-frequency (rf) photoinjector electron source over thirty years ago, peak performance demands have dictated the use of high accelerating electric fields. With recent strong advances in obtainable field values, attendant increases in beam brightness are expected to be dramatic. In this article, we examine the implementation of very high gradient acceleration in a high frequency, cryogenic rf photoinjector. We discuss in detail the effects of introducing, through an optimized rf cavity shape, rich spatial harmonic content in the accelerating modes in this device. Higher spatial harmonics give useful, enhanced linear focusing effects, as well as potentially deleterious nonlinear transverse forces. They also serve to strongly increase the ratio of average accelerating field to peak surface field, thus aiding in managing power and dark current-related challenges. We investigate two scenarios which are aimed at unique exploitation of the capabilities of this source. First, we investigate the obtaining of extremely high six-dimensional brightness for advanced free-electron laser applications. We also examine the use of a magnetized photocathode in the device for producing unprecedented low asymmetric emittance, high-current electron beams that reach linear collider-compatible performance. As both of the scenarios demand an advanced, compact solenoid design, we describe a novel cryogenic solenoid system. With the high field rf and magnetostatic structures introduced, we analyze the collective beam dynamics in these systems through theory and multi-particle simulations, including a particular emphasis on granularity effects associated with microscopic Coulomb interactions.

description: Detecting axionic dark matter induced electron or nucleon oscillating electric dipole moment (OEDM) has become a new way for dark matter searches. We re-examine such axion-spin couplings in external electromagnetic fields. We point out that axion-photon interaction induces an electron spin effective coupling, which is different from an OEDM. In particular, the axion-spin effective coupling is directly related to magnetic field rather than electric field. For axion-electron or axion-nucleon couplings, an OEDM of fermion is introduced, whose effect in ultralight axion cases depends on whether axion shift symmetry is manifest. Specifically, ultralight axionic dark matter interactions that do not obey the shift symmetry will be strongly constrained. We also extend the results to the case where axion has a finite velocity.
