description: We show a procedure for engineering effective interactions between two modes in a bimodal cavity. Our system consists of one or more two-level atoms, excited by a classical field, interacting with both modes. The two effective Hamiltonians have a similar form of a beam-splitter and quadratic beam-splitter interactions, respectively. We also demonstrate that the nonlinear Hamiltonian can be used to prepare an entangled coherent state, also known as multidimensional entangled coherent state, which has been pointed out as an important entanglement resource. We show that the nonlinear interaction parameter can be enhanced considering N independent atoms trapped inside a high-finesse optical cavity.

description: Using non-equilibrium Green's functions, we derive a formula for the electron current through a lead-molecule-lead nanojunction where the interactions are not restricted to the central region, but are spread throughout the system, including the leads and the lead-molecule interfaces. The current expression consists of two sets of terms. The first set corresponds to a generalised Meir and Wingreen expression where the leads' self-energies are renormalised by the interactions crossing at the molecule-lead contacts. The second set corresponds to inelastic scattering events in the leads arising from any arbitrary interaction, including electron-electron and electron-phonon coupling, treated beyond mean-field approximations. Using different levels of approximation, we are able to recover well-known expressions for the current. We also analyse how practical calculations can be performed with our formalism by using the new concept of generalised embedding potentials.

description: Recently, deep learning enabled the accurate segmentation of various diseases in medical imaging. These performances, however, typically demand large amounts of manual voxel annotations. This tedious process for volumetric data becomes more complex when not all required information is available in a single imaging domain as is the case for PET/CT data. We propose a multimodal interactive segmentation framework that mitigates these issues by combining anatomical and physiological cues from PET/CT data. Our framework utilizes the geodesic distance transform to represent the user annotations and we implement a novel ellipsoid-based user simulation scheme during training. We further propose two annotation interfaces and conduct a user study to estimate their usability. We evaluated our model on the in-domain validation dataset and an unseen PET/CT dataset. We make our code publicly available: https://github.com/verena-hallitschke/pet-ct-annotate.

description: In this paper we explore the effect of decaying dark matter (DDM) on large-scale structure and possible constraints from galaxy imaging surveys. DDM models have been studied, in part, as a way to address apparent discrepancies between the predictions of standard cold dark matter models and observations of galactic structure. Our study is aimed at developing independent constraints on these models. In such models, DDM decays into a less massive, stable dark matter (SDM) particle and a significantly lighter particle. The small mass splitting between the parent DDM and the daughter SDM provides the SDM with a recoil or "kick" velocity vk, inducing a free-streaming suppression of matter fluctuations. This suppression may be probed via weak lensing power spectra measured by a number of forthcoming imaging surveys that aim primarily to constrain dark energy. Using scales on which linear perturbation theory alone is valid (multipoles < 300), surveys like Euclid or LSST can be sensitive to vk > 90 km/s for lifetimes ~ 1-5 Gyr. To estimate more aggressive constraints, we model nonlinear corrections to lensing power using a simple halo evolution model that is in good agreement with numerical simulations. In our most ambitious forecasts, using multipoles < 3000, we find that imaging surveys can be sensitive to vk ~ 10 km/s for lifetimes < 10 Gyr. Lensing will provide a particularly interesting complement to existing constraints in that they will probe the long lifetime regime far better than contemporary techniques. A caveat to these ambitious forecasts is that the evolution of perturbations on nonlinear scales will need to be well calibrated by numerical simulations before they can be realized. This work motivates the pursuit of such a numerical simulation campaign to constrain dark matter with cosmological weak lensing.

description: During the 2010 rainy season in Yangbajing (4300 m above sea level) in Tibet, China, a long-duration count enhancement associated with thunderclouds was detected by a solar neutron telescope and neutron monitors installed at the Yangbajing Comic Ray Observatory. The event, lasting for $\sim$40 min, was observed on July 22, 2010. The solar neutron telescope detected significant $γ$-ray signals with energies $>$40 MeV in the event. Such a prolonged high-energy event has never been observed in association with thunderclouds, clearly suggesting that electron acceleration lasts for 40 min in thunderclouds. In addition, Monte Carlo simulations showed that $>$10-MeV $γ$ rays largely contribute to the neutron monitor signals, while $>$1-keV neutrons produced via a photonuclear reaction contribute relatively less to the signals. This result suggests that enhancements of neutron monitors during thunderstorms are not necessarily a clear evidence for neutron production, as previously thought.

Implicit Shape Model Trees: Recognition of 3-D Indoor Scenes and Prediction of Object Poses for Mobile Robots

description: We present an approach for mobile robots to recognize scenes in object arrangements distributed across cluttered environments. Recognition is enabled by intertwining the robot's search for objects and the assignment of found objects to scenes. Our scene model called "Implicit Shape Model (ISM) trees" allows these two tasks to be solved jointly. This article presents novel algorithms for ISM trees to recognize scenes and predict poses of searched objects. We define scenes as object sets in which some objects are connected via 3-D spatial relations. In previous work, we recognized scenes with single ISMs. However, single ISMs are prone to false positives. As a remedy, we have developed ISM trees, a hierarchical model consisting of multiple ISMs. This article contributes a recognition algorithm that now enables the use of ISM trees for scene recognition. ISM trees should be ideally generated from human demonstrations of object arrangements. As a suitable algorithm was not available, we introduce such a generation algorithm. In line with the active vision paradigm, we combined scene recognition and object search in previous work. However, an efficient algorithm was lacking to make this combination effective. Physical experiments show that this is now overcome with a new algorithm achieving efficient combination through predicted object poses.

Becoming a nurse: a study of phronesis and its possibilites

Publisher: name: Nursing

description: Bibliography: p. 173-186
description: Researchers often use sociological perspectives such as professionalization, socialization, and role theory when studying nursing students, or study the interactions between educators and students. These approaches specifically study what a student is becoming or how a student becomes a nurse, but do not focus on who is becoming a nurse. To understand the nursing student experience from an ontological perspective, I interviewed 10 nursing students (all of whom had previous undergraduate degrees) and asked them to describe their experience of becoming a nurse. Guided by Ricouer's understanding of mimesis as an interpretive approach, I develop four themes that reflect participants' experience in becoming a nurse. The first theme explores the temporal experience of students, meaning that their past experiences and imagined future ones all impact their present nursing practice. Secondly, nursing practice seems to be a "right fit" for these participants because their understanding of being a nurse is congruent with who they are as a person. Thirdly, participants continually judge the appropriateness of their own nursing practice and the practice of other nurses, and in the final theme I suggest that participants always consider the good of patient in their nursing practice. Considering the good occurs because participants are honoured that patients trust them so much, and participants return this honour when engaging with the patient. Based on my thematic analysis of the interviews, I construct the following ontology of nursing practice: (a) nursing practice is action, not just work; (b) a nurse's personal ontology is important for good nursing practice; (c) a nurse's character also influences her/his practice, and; (d) nursing practice is an ethical and moral practice. I introduce the ancient Greek concept of phronesis to help understand this ontology, and I conclude the thesis by exploring how phronesis might influence nurse educators and nursing curricula.
The nature of 4f electron magnetism in the diluted ferromagnetic Kondo lattice, CeIr2B2

description: We report on the physical properties of the series Ce_(1-x)La_xIr_2B_2 (x D 0-0.9), obtained by means of magnetization, heat capacity and electrical resistivity measurements as a function of temperature (down to 0.7 K for the latter two measurements). The Curie temperature of CeIr2B2 (?5 K) is lowered due to La substitution, as expected. However, no quantum critical point or 'non-Fermi liquid' behavior was observed even in the dilute limit of x D 0:9. Interestingly, ferromagnetic ordering persists even for Ce0:1La0:9Ir2B2, below 0.8 K. Among the Ce systems, CeIr2B2 is one of the compounds in which direct 4f-4f interaction does not appear to play any role in the magnetism, which is controlled by the indirect exchange interaction alone. In this compound, the Kondo effect persists in the ferromagnetic ordered state, as inferred from the entropy data.
Combination of searches for invisible decays of the Higgs boson using 139 fb$^{-1}$ of proton-proton collision data at $\sqrt{s} = 13$ TeV collected with the ATLAS experiment

description: Many extensions of the Standard Model predict the production of dark matter particles at the LHC. Sufficiently light dark matter particles may be produced in decays of the Higgs boson that would appear invisible to the detector. This Letter presents a statistical combination of searches for H $\rightarrow$ invisible decays where multiple production modes of the Standard Model Higgs boson are considered. These searches are performed with the ATLAS detector using 139 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $\sqrt{s} =13$ TeV at the LHC. In combination with the results at $\sqrt{s} =7$ TeV and 8 TeV, an upper limit on the H $\rightarrow$ invisible branching ratio of 0.107 (0.077) at the 95% confidence level is observed (expected). These results are also interpreted in the context of models where the 125 GeV Higgs boson acts as a portal to dark matter, and limits are set on the scattering cross-section of weakly interacting massive particles and nucleons.

description: We present radio light curves and spectra of the classical nova V1723 Aql obtained with the Expanded Very Large Array (EVLA). This is the first paper to showcase results from the EVLA Nova Project, which comprises a team of observers and theorists utilizing the greatly enhanced sensitivity and frequency coverage of EVLA radio observations, along with observations at other wavelengths, to reach a deeper understanding of the energetics, morphology, and temporal characteristics of nova explosions. Our observations of V1723 Aql span 1-37 GHz in frequency, and we report on data from 14-175 days following the time of the nova explosion. The broad frequency coverage and frequent monitoring show that the radio behavior of V1723 Aql does not follow the classic Hubble-flow model of homologous spherically expanding thermal ejecta. The spectra are always at least partially optically thin, and the flux rises on faster timescales than can be reproduced with linear expansion. Therefore, any description of the underlying physical processes must go beyond this simple picture. The unusual spectral properties and light curve evolution might be explained by multiple emitting regions or shocked material. Indeed, X-ray observations from Swift reveal that shocks are likely present.

description: To cope with the increasing demand of wireless communication services multi-carrier systems are being used. Radio resources are very limited and efficient usages of these resources are inevitable to get optimum performance of the system. Paging channel is a low-bandwidth channel and one of the most important channels on which system performance depends significantly. Therefore it is vulnerable to even moderate overloads. In this paper, an efficient paging algorithm, Concurrent Search, is proposed for efficient use of paging channel in Multi- carrier CDMA system instead of existing sequential searching algorithm. It is shown by the simulation that the paging performance in proposed algorithm is far better than the existing system.

description: Vibronic coupling constants in the monoanionic, trianionic, and excited states of picene are evaluated from the total energy gradients using the density functional theory. Employing the calculated vibronic coupling constants in the excited state of the neutral molecule, electron energy loss spectrum (EELS) is simulated to be compared with the experimental spectrum. The calculated vibronic coupling constants are analyzed in terms of the vibronic coupling density which enables us to analyze vibronic couplings based on the relation between the electronic and vibrational structures. The vibronic coupling constants reported by Kato et al. [J. Chem. Phys. 116, 3420 (2002) and Phys. Rev. Lett. 107, 077001 (2011)] are critically discussed based on the vibronic coupling density analysis.

description: Quorum sensing (QS) mimickers can be used as an effective tool to disrupt biofilms which consist of communicating bacteria and extracellular polymeric substances. In this paper, a stochastic biofilm disruption model based on the usage of QS mimickers is proposed. A chemical reaction network (CRN) involving four different states is employed to model the biological processes during the biofilm formation and its disruption via QS mimickers. In addition, a state-based stochastic simulation algorithm is proposed to simulate this CRN. The proposed model is validated by the in vitro experimental results of Pseudomonas aeruginosa biofilm and its disruption by rosmarinic acid as the QS mimicker. Our results show that there is an uncertainty in state transitions due to the effect of the randomness in the CRN. In addition to the QS activation threshold, the presented work demonstrates that there are underlying two more thresholds for the disruption of EPS and bacteria, which provides a realistic modeling for biofilm disruption with QS mimickers.

description: Despite decades of 'development', hunger and poverty persist in rural areas around the world. With the implementation of structural adjustment programs, regional trade agreements and the World Trade Organization (WTO) agreements, rural landscapes everywhere are undergoing rapid change. National governments are restructuring agricultural policies to facilitate greater integration into an international market-driven economy. Concerted attempts to exclude peasants and small-scale farming peoples interests in decision-making and rural policy development have been accompanied by the formation of an international peasant and farm movement, the Via Campesina, which emerged in 1993. This dissertation examines the response of peasant and farm organizations to the increased globalization of a 'modem', industrial and neoliberal model of agriculture by analyzing the formation, consolidation and functioning of the Via Campesina. To date, studies of transnational anti-globalization movements have virtually ignored agrarian activism. Yet, in many countries peasants and farmers have been at the forefront of national struggles against globalization and through the Via Campesina peasant-based resistance has now moved beyond national borders. At the international level peasants and farmers are now leading the way by introducing new concepts like food sovereignty. They are also using the most powerful tools available to social movements - that of non-participation and delegitimization. The Via Campesina is using three traditional weapons of the weak - organization, cooperation and community to redefine rural development and to build an alternative model for rural communities, one that is based on social justice, gender equality and environmental sustainability. Using an analysis of Via Campesina conference proceedings, minutes of the meetings of the Women's Commission and the International Coordination Commission of the Via Campesina, participant observation in numerous Via Campesina events, interviews with key farm leaders, and field work conducted in Mexico, Canada and India, this study explores the main issues, positions, strategies and collective actions of the Via Campesina. In doing so it provides insights into the nature and extent of current agrarian activism.
Ongoing surveys for close binary central stars and wider implications

description: Binary central stars have long been invoked to explain the vexing shapes of planetary nebulae (PNe) despite there being scant direct evidence to support this hypothesis. Modern large-scale surveys and improved observing strategies have allowed us to significantly boost the number of known close binary central stars and estimate at least 20% of PNe have close binary nuclei that passed through a common-envelope (CE) phase. The larger sample of post-CE nebulae appears to have a high proportion of bipolar nebulae, low-ionisation structures (especially in SN1987A-like rings) and polar outflows or jets. These trends are guiding our target selection in ongoing multi-epoch spectroscopic and photometric surveys for new binaries. Multiple new discoveries are being uncovered that further strengthen the connection between post-CE trends and close binaries. These ongoing surveys also have wider implications for understanding CE evolution, low-ionisation structure and jet formation, spectral classification of central stars, asymptotic giant branch (AGB) nucleosynthesis and dust obscuration events in PNe.

description: Now a day's Heterogeneous wireless network is a promising field of research interest. Various challenges exist in this hybrid combination like load balancing, resource management and so on. In this paper we introduce a reliable load balancing architecture for heterogeneous wireless communications to ensure certain level of quality of service. To conquer the problem of centralized and distributed design, a semi distributed load balancing architecture for multiple access networks is introduced. In this grid based design multiple Load and Mobile Agent Management Units is incorporated. To prove the compactness of the design, integrated reliability, signalling overhead and total processing time is calculated. And finally simulation result shows that overall system performance is improved by enhancing reliability, reducing signalling overhead and processing time.

description: Intraseasonal variations of the South Asian Summer Monsoon (SASM) contain alternating extreme rainfall (active) and low rainfall (break) phases impacting agriculture and economies. Their timing and spatial location are dominated by the Boreal Summer Intraseasonal Oscillation (BSISO), a quasi-periodic movement of convective precipitation from the equatorial Indian Ocean to the Western Pacific. However, observed deviations from the BSISO's canonical north-eastward propagation are poorly understood. Utilizing climate networks to characterize how active phases propagate within the SASM domain and using clustering analysis, we reveal three distinct modes of BSISO propagation: north-eastward, eastward-blocked, and stationary. We further show that Pacific sea surface temperatures modulate the modes - with El Niño- (La Niña-) like conditions favoring the stationary (eastward-blocked) - by changing local zonal and meridional overturning circulations and the BSISO Kelvin wave component. Using these insights, we demonstrate the potential for early warning signals of extreme rainfall until four weeks in advance.

description: Η λεϊσμανίαση είναι μια παρασιτική ασθένεια που προκαλείται από τα πρωτόζωα Leishmania spp. που ανήκουν στην οικογένεια των τρυπανοσωματίδων. Εκδηλώνε-ται σε σπλαχνικές, δερματικές και βλεννογονοδερματικές μορφές ανάλογα το εί-δος. Είναι μια τροπική παραμελημένη νόσος που συναντάται κυρίως στη Λεκάνη της Μεσογείου, τη Μέση Ανατολή, την Κεντρική Ασία αλλά σταδιακά και στον υπόλοιπο κόσμο με κρούσματα που φτάνουν το 1 εκατομμύριο ετησίως. Η τρέχουσα φαρμακευτική θεραπεία της λεϊσμανίασης αποτελεί εμπόδιο στην εξάλειψη της νοσου καθώς παρουσιάζει υψηλό κόστος, κυτταροτοξικότητα και σταδιακή ανθεκτικότητα των παρασίτων σε πολλά φάρμακα. Προς αποφυγή όλων των παραπάνω αντενδείξεων τέθηκε η ανάγκη εύρεσης νέων θεραπευτικών προσεγγίσεων. Αυτές περιλαμβάνουν σκευάσματα φυσικής προέλευσης με μηχανισμούς δράσης διαφορετικούς από αυτούς των κλασσικών χημικών φαρμάκων, όπως φυτά και ορυκτά, τα οποία δεν παρουσιάζουν τοξικότητα, έχουν χαμηλό κόστος και είναι εύκολη η διάθεσή τους. Μια κατηγορία των σκευασμάτων αυτών αποτελούν και τα ομοιοπαθητικά φάρμα-κα, στα οποία αναφέρεται και η παρούσα διπλωματική εργασία. Οι ουσίες που χρησιμοποιήθηκαν είναι το Andrographis paniculata, Ferrum arsenicum και Anti-monium crudum. Το επιπλέον χρησιμοποιήθηκε σε διάφορες συγκεντρώσεις. Τα σκευάσματα που παράχθηκαν από τις παραπάνω ουσίες χρησιμοποιήθηκαν σε in vitro πειράματα για αξιολόγηση της αντιλεϊσμανιακής τους δράσης σε ποικίλες δυναμοποιήσεις με στόχο τη χρήση τους σαν εναλλακτική ή συμπληρωματική θεραπεία για την αντιμετώπιση της ασθένειας. Τα πειράματα εφαρμόστηκαν σε ενδοκυτταρικές αμαστιγωτές και προμαστιγωτές μορφές του παρασίτου. Στην πλειοψηφία των πειραματικών δοκιμών η αναστολή της δράσης των ουσιών ήταν μικρότερη του 20 %. Ενδιαφέρον παρουσιάζει η δράση της ουσίας Antimonium crudum, η οποία χρησιμοποιήθηκε σε διάφορες συγκεντρώσεις σε προμαστιγώτες και έδειξε μια προσωρινή ανασταλτική δράση σε ποσοστό 38.07 %, η οποία παρέρχεται μετα από 72 ώρες. Θα μπορούσαν να γίνουν περεταίρω δοκιμές μελλοντικά για μια πιο σαφή εικόνα και διερεύνηση περισσότερων παραγόντων με σκοπό την αναστολή του παρασίτου Leishmania spp.

description: When two solids are separated by a vacuum gap of thickness smaller than the wavelength of acoustic phonons, the latter can tunnel across the gap thanks to van der Waals forces or electrostatic interactions. Here we show that these mechanical vibration modes can also contribute significantly, at the atomic scale, to the nonlocal radiative response of polar materials. By combining molecular-dynamics simulations with fluctuational-electrodynamics theory, we investigate the near-field radiative heat transfer between two slabs due to this optomechanical coupling and highlight its dominant role at cryogenic temperatures. These results pave the way to exciting avenues for the control of heat flux and the development of cooling strategies at the atomic scale.

description: We study a readout scheme of superconducting flux qubit state with a Cooper pair box as a transmon. The qubit states consist of the superpositions of two degenerate states where the charge and phase degrees of freedom are entangled. Owing to the robustness of transmon against external fluctuations, our readout scheme enables the quantum non-demolition and single-shot measurement of flux qubit states. The qubit state readout can be performed by using the non-linear Josephson amplifiers after a $π/2$-rotation driven by an ac-electric field.

description: In this paper we study perturbatively an extension of the Stelle higher derivative gravity involving an infinite number of derivative terms. We know that the usual quadratic action is renormalizable but suffers of the unitarity problem because of the presence of a ghost (state of negative norm) in the theory. The new theory is instead ghost-free since the introduction of (in general) two entire functions in the model with the property do not introduce new poles in the propagator. The local high derivative theory is recovered expanding the entire functions to the lowest order in the mass scale of the theory. Any truncation of the entire functions gives rise to the unitarity violation but if we keep all the infinite series we do not fall into these troubles. The theory is renormalizable at one loop and finite from two loops on. Since only a finite number of graphs are divergent then the theory is super-renormalizable. We analyze the fractal properties of the theory at high energy showing a reduction of the spacetime dimension at short scales. Black hole spherical symmetric solutions are also studied omitting the high curvature corrections in the equation of motions. The solutions are regular and the classical singularity is replaced by a "de Sitter-like core" in r=0. Black holes may show a "multi-horizon" structure depending on the value of the mass.

description: We introduce and study a model in one dimension of $N$ run-and-tumble particles (RTP) which repel each other logarithmically in the presence of an external quadratic potential. This is an "active'' version of the well-known Dyson Brownian motion (DBM) where the particles are subjected to a telegraphic noise, with two possible states $\pm$ with velocity $\pm v_0$. We study analytically and numerically two different versions of this model. In model I a particle only interacts with particles in the same state, while in model II all the particles interact with each other. In the large time limit, both models converge to a steady state where the stationary density has a finite support. For finite $N$, the stationary density exhibits singularities, which disappear when $N \to +\infty$. In that limit, for model I, using a Dean-Kawasaki approach, we show that the stationary density of $+$ (respectively $-$) particles deviates from the DBM Wigner semi-circular shape, and vanishes with an exponent $3/2$ at one of the edges. In model II, the Dean-Kawasaki approach fails but we obtain strong evidence that the density in the large $N$ limit retains a Wigner semi-circular shape.

description: A superconducting qubit coupled to a read-out resonator is currently the building block of multiple quantum computing as well as quantum optics experiments. A typical qubit-resonator system is coupled in the dispersive regime, where the detuning between qubit and resonator is much greater than the coupling between them. In this work, we fabricated and measured a superconducting transmon-resonator system in the non-dispersive regime. The dressed states formed by the mixing of the bare qubit and resonator states can be further mixed by applying a drive on the qubit, leading to the formation of polariton states. We report experimental studies of transitions between polariton states at varying driving powers and frequencies and show how the non-dispersive coupling of the higher levels of the qubit-resonator system modifies the polariton eigenstates and the corresponding transition frequencies. We also report close agreement with numerical results obtained from a driven Jaynes-Cummings Model beyond the dispersive regime.
