description: The accurate determination of electronic temperatures in metallic nanostructures is essential for many technological applications, like plasmon-enhanced catalysis or lithographic nanofabrication procedures. In this Letter we demonstrate that the electronic temperature can be accurately measured by the shape of the tunnel electroluminescence emission edge in tunnel plasmonic nanocavities, which follows a universal thermal distribution with the bias voltage as the chemical potential of the photon population. A significant deviation between electronic and lattice temperatures is found below 30 K for tunnel currents larger than 15 nA. This deviation is rationalized as the result of a two-electron process in which the second electron excites plasmon modes with an energy distribution that reflects the higher temperature following the first tunneling event. These results dispel a long-standing controversy on the nature of overbias emission in tunnel junctions and adds a new method for the determination of electronic temperatures and quasiparticle dynamics.

description: For quantum systems with high purity, we find all observables that, when continuously monitored, maximize the instantaneous reduction in the von Neumann entropy. This allows us to obtain all locally optimal feedback protocols with strong feedback, and explicit expressions for the best such protocols for systems of size N <= 4. We also show that for a qutrit the locally optimal protocol is the optimal protocol for a given range of control times, and derive an upper bound on all optimal protocols with strong feedback.

description: Στην παρούσα διπλωματική εργασία μελετήθηκε η άπειρη πυρηνική ύλη μέσα από την θεωρία της Κβαντικής Αδροδυναμικής με την προσέγγιση του μέσου πεδίου για θερμοκρασία μηδέν. Η εργασία χωρίζεται σε τρία μέρη. Βασικός στόχος και στα τρία μέρη είναι η εξαγωγή της καταστατικής εξίσωσης και η εξαγωγή των σωστών τιμών της ενέργειας σύνδεσης -16 MeV για την πυκνότητα κορεσμού 0.16 fm^{-3}. Στο πρώτο μέρος μελετήθηκε το μοντέλο Walecka γνωστό και ως σ-ω μοντέλο για θερμοκρασία μηδέν. Το μοντέλο αυτό αποτελεί την απλούστερη προσέγγιση για την μελέτη της πυρηνικής ύλης, περιγράφοντας την αλληλεπίδραση των νουκλεονίων μέσω του ανταγωνισμού ενός ελκτικού (βαθμωτό σ μεσόνιο) και ενός απωστικού (διανυσματικό ω μεσόνιο) πεδίου. Αναπαράγει σωστά την ενέργεια σύνδεσης αλλά όχι τον συντελεστή συμπιεστότητας. Στο δεύτερο μέρος, για να καταφέρουμε να βελτιώσουμε τα αποτελέσματα του σ-ω μοντέλου εισάγαμε το δυναμικό των Boguta & Bodmer στην Λαγκρανζιανή, δηλαδή δυο επιπλέον μη γραμμικούς όρους, καταφέρνοντας έτσι ώστε να αναπαράγουμε σωστά την ενέργεια σύνδεσης και τον συντελεστή συμπιεστότητας. Στο τρίτο και τελευταίο μέρος, εισήχθει στο φορμαλισμό η θερμοκρασία , με στόχο την σύγκριση της καταστατικής εξίσωσης για Τ = 0, 10, 20 MeV και την παρατήρηση της αλλαγής φάσης που συμβαίνει στην πυρηνική ύλη καθώς αυξάνει η θερμοκρασία. Σε όλη τη διπλωματική εργασία χρησιμοποιήθηκαν στοιχεία θεωρίας Σχετικιστικής Κβαντομηχανικής και λαγκρανζιανού φορμαλισμού.
description: In this master thesis we studied the infinite, nuclear matter in the framework of Quantum Hadrodynamics with the mean field approximation. This thesis is devided in three parts. The basic goal is to reproduce the equation of state and the binding energy -16 MeV for the saturation density 0.16 fm^{-3}. In the first part, we studied the Walecka model, known as sigma-omega model for T = 0. This model is the simplest approximation of nuclear matter and is describing the nucleon nucleon interaction using an attractive scalar field sigma and a repulsive vector field omega. It reproduces correctly the binding energy but it has a big value for commpresibiity modulus. In the second part, we added two non-linear terms in the Lagrangian, known as Boguta and Bodmer potential, in order to produce the correct value for binding energy and the compression modulus. In the third and last part, we introduced the temprature in the formalism in order to study the phase transition in the nuclear matter while the temprature rise up to 10 and 20 MeV. In this thesis, we used the theory of Quantum relativity and the lagrangian formalism.

description: As defined in the Cambridge International English, “a proverb is a short, familiar utterance of folk wisdom, usually condensed in form, incorporating a bold image and often a chime that catches memory.” That is why Russell considers proverbs “the wisdom of many and the mind of one.” Most proverbs are short and comprehensive, a proverb can convey more philosophical meanings in life than the few words it contains. Sometimes a proverb can take several turns of speech at once, this fact alone can show how laconic and excellent the language of proverbs is. This is why proverbs are often viewed as the essence of the language. The article provides a brief step-by-step analysis of the various rhetorical forms commonly used in proverbs. Analysis of the form of speech of proverbs in Chinese and English, contributing to a more complete understanding of the internal meaning of proverbs and their correct use. For English learners, proverbs are also a good teaching language, as they can not only teach them to express their ideas succinctly, but also teach them to write effectively using various rhetorical expressions.

description: We report the first no-core shell model results for $^{48}Ca$, $^{48}Sc$ and $^{48}Ti$ with derived and modified two-body Hamiltonians. We use an oscillator basis with a limited $\hbarΩ$ range around $45/A^{1/3}-25/A^{2/3} = 10.5 MeV$ and a limited model space up to $1\hbarΩ$. No single-particle energies are used. We find that the charge dependence of the bulk binding energy of eight A=48 nuclei is reasonably described with an effective Hamiltonian derived from the CD-Bonn interaction while there is an overall underbinding by about 0.4 MeV/nucleon. However, the resulting spectra exhibit deficiencies that are anticipated due to: (1) basis space limitations and/or the absence of effective many-body interactions; and, (2) the absence of genuine three-nucleon interactions. We then introduce additive isospin-dependent central terms plus a tensor force to our Hamiltonian and achieve accurate binding energies and reasonable spectra for all three nuclei. The resulting no-core shell model opens a path for applications to the double-beta ($ββ$) decay process.

Subjects: Applied Computer Science

description: Massive Open Online Course (MOOC) is an emerging learning platform aimed at infinite participation and access through the Internet. Recently, MOOC is globally becoming a key instrument in digitally mediated learning and teaching, due to its ability to provide interactive user forums to support community interactions among participants and instructors. Despite its global acceptance, countries in sub-Saharan Africa suffer some drawbacks within the context of awareness and adoption. Kano state is one of the cities in Sub-Saharan Africa with a high population where MOOCs participation is significantly needed. Therefore, the rationale of this study is to appraise the level of awareness, perceived benefits and challenges of MOOCs adoption among University students of Kano State, Nigeria. The study was conducted in form of a survey using structured questionnaire administered to three hundred (300) randomly selected respondents. Finding from the study revealed a variation in the level of awareness among IT and non IT inclined students. The investigation of MOOC benefits indicates improved learning performance and effectiveness among study samples. The study further revealed user unfriendliness, inadequate Internet connectivity, power instability and cost of enrolments as factors influencing slow adoption of MOOC. The evidence from the study suggests that, awareness and adoption of MOOCs can be enhanced through establishment of hubs, provision of national accredited curriculum and subsidized cost of enrollments.

description: It is shown, theoretically and experimentally, that at any type-II spontaneous parametric down-conversion (SPDC) phase matching, the decoherence-free singlet Bell state is always present within the natural bandwidth and can be filtered out by a proper spectral selection. Instead of the frequency selection, one can perform time selection of the two-photon time amplitude at the output of a dispersive fibre. Applications to quantum communication are outlined.

description: The development of van der Waals (vdW) crystals and their heterostructures has created a fascinating platform for exploring optoelectronic properties in the two-dimensional (2D) limit. With the recent discovery of 2D magnets, the control of the spin degree of freedom can be integrated to realize 2D spin-optoelectronics with spontaneous time-reversal symmetry breaking. Here, we report spin photovoltaic effects in vdW heterostructures of atomically thin magnet chromium triiodide (CrI3) sandwiched by graphene contacts. In the absence of a magnetic field, the photocurrent displays a distinct dependence on light helicity, which can be tuned by varying the magnetic states and photon energy. Circular polarization-resolved absorption measurements reveal that these observations originate from magnetic-order-coupled and thus helicity-dependent charge-transfer exciton states. The photocurrent displays multiple plateaus as the magnetic field is swept, which are associated with different spin configurations enabled by the layered antiferromagnetism and spin-flip transitions in CrI3. Remarkably, giant photo-magnetocurrent is observed, which tends to infinity for a small applied bias. Our results pave the way to explore emergent photo-spintronics by engineering magnetic vdW heterostructures.

Publisher: name: University of British Columbia
Year: 2009

description: A computer model was developed for predicting heating, ventilation and CO 2 enrichment requirements for a standard tomato greenhouse range located in the Fraser valley of British Columbia. Predicted and measured data were compared for typical cases of outside weather conditions. The mathematical model which is comprised of heat and mass balances for the greenhouse thermal environment and crop photosynthesis has yielded reasonably accurate simulation results compared to observed values. Heating requirement was predicted to within 10-14% for three typical cases of weather conditions, but deviated by 35% from actual energy consumption data under one situation(Case #3). Predicted ventilation demand also followed closely the trend of observed vent openings data, except for Case #4 . Energy saving is achieved in different manners for the four cases.
Evolution Equation of Phenotype Distribution: General Formulation and Application to Error Catastrophe

description: An equation describing the evolution of phenotypic distribution is derived using methods developed in statistical physics. The equation is solved by using the singular perturbation method, and assuming that the number of bases in the genetic sequence is large. Applying the equation to the mutation-selection model by Eigen provides the critical mutation rate for the error catastrophe. Phenotypic fluctuation of clones (individuals sharing the same gene) is introduced into this evolution equation. With this formalism, it is found that the critical mutation rate is sometimes increased by the phenotypic fluctuations, i.e., noise can enhance robustness of a fitted state to mutation. Our formalism is systematic and general, while approximations to derive more tractable evolution equations are also discussed.

description: Στα πλαίσια της παρούσας μεταπτυχιακής διπλωματικής εργασίας σχεδιάστηκε και κατασκευάστηκε ένα laser Ti:Sapphire σε διάταξη συμμετρικής αλλά και ασύμμετρης κοιλότητας Z. Ένα σημαντικό μέρος της εργασίας αφιερώθηκε στην σχεδίαση και κατασκευή ενός συστήματος ψύξης του κρυστάλλου βασισμένου σε θερμοηλεκτρικό στοιχείο (TEC) με χρήση νερού ως ψυκτικού μέσου. Η τελική λειτουργία του συστήματος ήταν επιτυχής και επιτρέπει την ψύξη του νερού έως και τους 14 οC σε πλήρη λειτουργία του laser (θερμοκρασία περιβάλλοντος 25 οC). Σε σχέση με την κοιλότητα του laser, υπολογίστηκαν τα γεωμετρικά χαρακτηριστικά της κοιλότητας για την εξάλειψη των σφαλμάτων του αστιγματισμού αλλά και της παλμικής λειτουργίας της σε ασύμμετρη διάταξη με κατάλληλη γραμμή πρισμάτων για την αντιστάθμιση της διασποράς δεύτερης τάξης κυρίως εξαιτίας του κρυστάλλου. Η λειτουργία της κοιλότητας σε συμμετρική διάταξη Ζ απέδωσε 185 mW γύρω στα 800 nm για οπτική άντληση στα 4W@532 nm
description: During the course of this master thesis, a Ti:Sapphire laser has been designed and constructed both in a symmetric and an asymmetric Z cavity arrangement. A significant part of the work was devoted to the design and construction of a water cooling system for the laser crystal, based on a thermoelectric component (TEC). The system was successful in cooling the laser crystal at normal laser operation by circulation of water at a temperature as low as 14 oC (25oC ambient temperature). With regard to the laser cavity, its geometric characteristics where calculated to minimize astigmatism and compensate for the second order optical dispersion in the case of pulsed operation by an appropriate prism line. The laser operating at a symmetric Z cavity arrangement delivered 185 mW around 800 nm with optical pumping of 4W@532 nm.

description: We present the results of 11 nights of CCD unfiltered photometry of V4743 Sgr (Nova Sgr 2002 # 3) from 2003 and 2005. We find two periods of 0.2799 d ~ 6.7 h and 0.01642 d ~ 24 min in the 2005 data. The long period is also present in the 2003 data, but only weak evidence of the shorter period is found in this year. The 24-min period is somewhat longer than the 22-min period, which was detected from X-ray observations. We suggest that the 6.7-h periodicity represents the orbital period of the underlying binary system and that the 24-min period is the beat periodicity between the orbital period and the X-ray period, which is presumably the spin period of the white dwarf. Thus, V4743 Sgr should be classified as an intermediate polar (DQ Her star). About six months after the nova outburst, the optical light curve of V4743 Sgr seemed to show quasi-periodic oscillations, which are typical of the transient phase in classical nova. Therefore, our results support the previous suggestion that the trans ition phase in novae may be related to intermediate polars.

description: Large labeled data sets are one of the essential basics of modern deep learning techniques. Therefore, there is an increasing need for tools that allow to label large amounts of data as intuitively as possible. In this paper, we introduce SALT, a tool to semi-automatically annotate RGB-D video sequences to generate 3D bounding boxes for full six Degrees of Freedom (DoF) object poses, as well as pixel-level instance segmentation masks for both RGB and depth. Besides bounding box propagation through various interpolation techniques, as well as algorithmically guided instance segmentation, our pipeline also provides built-in pre-processing functionalities to facilitate the data set creation process. By making full use of SALT, annotation time can be reduced by a factor of up to 33.95 for bounding box creation and 8.55 for RGB segmentation without compromising the quality of the automatically generated ground truth.

description: With the wide adoption of black-box models, instance-based \emph{post hoc} explanation tools, such as LIME and SHAP became increasingly popular. These tools produce explanations, pinpointing contributions of key features associated with a given prediction. However, the obtained explanations remain at the raw feature level and are not necessarily understandable by a human expert without extensive domain knowledge. We propose ReEx (Reasoning with Explanations), a method applicable to explanations generated by arbitrary instance-level explainers, such as SHAP. By using background knowledge in the form of ontologies, ReEx generalizes instance explanations in a least general generalization-like manner. The resulting symbolic descriptions are specific for individual classes and offer generalizations based on the explainer's output. The derived semantic explanations are potentially more informative, as they describe the key attributes in the context of more general background knowledge, e.g., at the biological process level. We showcase ReEx's performance on nine biological data sets, showing that compact, semantic explanations can be obtained and are more informative than generic ontology mappings that link terms directly to feature names. ReEx is offered as a simple-to-use Python library and is compatible with tools such as SHAP and similar. To our knowledge, this is one of the first methods that directly couples semantic reasoning with contemporary model explanation methods. This paper is a preprint.

description: Van der Waals moiré materials have emerged as a highly controllable platform to study the electronic correlation phenomena. In particular, robust correlated insulating states have recently been discovered at both integer and fractional filling factors of the semiconductor moiré systems. Here, we reveal the thermodynamic properties of these states by measuring the gate capacitance of MoSe2/WS2 moiré superlattices. We observe a series of incompressible states for filling factor 0 - 8 and anomalously large capacitance (nearly 60% above the device's geometrical capacitance) in the intervening compressible regions. The anomalously large capacitance is most pronounced at small filling factor, below the melting temperature of the charge-ordered states, and for small sample-gate separation. It is a manifestation of the device-geometry-dependent Coulomb interaction between electrons and phase mixing of the charge-ordered states. We have further extracted the thermodynamic gap of the correlated insulating states and the entropy of the capacitive device. The results not only establish capacitance as a powerful probe of the correlated states in semiconductor moiré systems, but also demonstrate control of the extended Coulomb interaction in these materials via sample-gate coupling.

Specifically, Close-in and ABG path loss models were studied so as to estimate the cell radius for urban, suburban and rural areas and also to estimate the maximum distance for backhaul links. Moreover, an estimation is given on the number of required base stations and the coverage map of Hong Kong is presented in the case of millimeter wave bands being utilized. For the creation of the coverage map, suitable code in Java programming language was developed with the use of Geotools libraries. The required number of base stations was compared to the number of base stations for a LTE mobile network that is operating in the area of Hong Kong using data that were acquired from the OpenCellID database. As a conclusion, in the cases of urban environments where there is high density of operational base stations, it can be expected that a small increase in the number of base stations will be required for a mobile communication network utilizing millimeter wave bands in the area of 28 GHz.

description: We have fabricated and studied a ballistic one-dimensional p-type quantum wire using an undoped AlGaAs/GaAs heterostructure. The absence of modulation doping eliminates remote ionized impurity scattering and allows high mobilities to be achieved over a wide range of hole densities, and in particular, at very low densities where carrier-carrier interactions are strongest. The device exhibits clear quantized conductance plateaus with highly stable gate characteristics. These devices provide opportunities for studying spin-orbit coupling and interaction effects in mesoscopic hole systems in the strong interaction regime where rs > 10.

description: Communicating the robot state is vital to creating an efficient and trustworthy collaboration between humans and collaborative robots (cobots). Standard approaches for Robot-to-human communication face difficulties in industry settings, e.g., because of high noise levels or certain visibility requirements. Therefore, this paper presents zoomorphic gestures based on dog body language as a possible alternative for communicating the state of appearance-constrained cobots. For this purpose, we conduct a visual communication benchmark comparing zoomorphic gestures, abstract gestures, and light displays. We investigate the modalities regarding intuitive understanding, user experience, and user preference. In a first user study (n = 93), we evaluate our proposed design guidelines for all visual modalities. A second user study (n = 214) constituting the benchmark indicates that intuitive understanding and user experience are highest for both gesture-based modalities. Furthermore, zoomorphic gestures are considerably preferred over other modalities. These findings indicate that zoomorphic gestures with their playful nature are especially suitable for novel users and may decrease initial inhibitions.

description: Fluctuation dynamo action has been obtained for a flow previously used to model fluid turbulence, where the sensitivity of the magnetic field parameters to the kinetic energy spectrum can be explored. We apply quantitative morphology diagnostics, based on the Minkowski functionals, to magnetic fields produced by the kinematic fluctuation dynamo to show that magnetic structures are predominantly filamentary rather than sheet-like. Our results suggest that the thickness, width and length of the structures scale differently with magnetic Reynolds number.

Kinematics and star formation toward W33: a central hub as a hub--filament system

description: We performed a large-scale mapping observation toward the W33 complex and its surroundings, covering an area of $1.3^\circ \times 1.0^\circ$ , in $^{12}$CO (1-0), $^{13}$CO (1-0), and C$^{18}$O (1-0) lines from the Purple Mountain Observatory (PMO). We found a new hub--filament system ranging from 30 to 38.5 \kms located at the W33 complex. Three supercritical filaments are directly converging into the central hub W33. Velocity gradients are detected along the filaments and the accretion rates are in order of $\rm 10^{-3}\,M_\odot\, yr^{-1}$. The central hub W33 has a total mass of $\rm\sim 1.8\times10^5\,M_\odot$, accounting for $\sim 60\%$ of the mass of the hub--filament system. This indicates that the central hub is the mass reservoir of the hub-filament system. Furthermore, 49 ATLASGAL clumps are associated with the hub--filament system. We find $57\%$ of the clumps to be situated in the central hub W33 and clustered at the intersections between the filaments and the W33 complex. Moreover, the distribution of Class I young stellar objects (YSOs) forms a structure resembling the hub--filament system and peaks at where the clumps group; it seems to suggest that the mechanisms of clump formation and star formation in this region are correlated. Gas flows along the filaments are likely to feed the materials into the intersections and lead to the clustering and formation of the clumps in the hub--filament system W33. The star formation in the intersections between the filaments and the W33 complex might be triggered by the motion of gas converging into the intersections.

description: Nowadays the development of high-field magnets strongly relies on the performance of superconducting materials. Iron-based superconductors exhibit high upper critical fields and low electromagnetic anisotropy, making them particularly attractive for high-field applications, especially in particle accelerator magnets, nuclear magnetic resonance spectrometers, medical magnetic resonance imaging systems and nuclear fusion reactors. Herein, through an industrially scalable and cost-effective manufacturing strategy, a practical level critical current density up to 1.1x10^5 A/cm2 at 4.2 K in an external magnetic field of 10 T was achieved in Cu/Ag composite sheathed Ba0.6K0.4Fe2As2 superconducting tapes. The preparation strategy combines flat rolling to induce grain texture and a subsequent hot-isostatic-pressing densification. By varying the parameters of rolling, the degree of grain texture was engineered. It is found that the transport properties of the Ba1-xKxFe2As2 tapes can be enhanced by applying a large amount of deformation during rolling, which can be attributed to the improved degree of c-axis texture. Microstructure characterizations on the highest-performance tape demonstrate that the Ba1-xKxFe2As2 phase has a uniform element distribution and small grains with good connectivity. Grain boundary pinning is consequently enhanced as proved by large currents circulating through the sample even at 25 K. Our work proves that Cu/Ag composite sheathed Ba1-xKxFe2As2 superconducting tapes can be a promising competitor for practical high-field applications in terms of the viable, scalable and cost-effective fabrication strategy applied and the high transport properties achieved in this work.

description: We demonstrate the accuracy of the hypernetted chain closure and of the mean-field approximation for the calculation of the fluid-state properties of systems interacting by means of bounded and positive-definite pair potentials with oscillating Fourier transforms. Subsequently, we prove the validity of a bilinear, random-phase density functional for arbitrary inhomogeneous phases of the same systems. On the basis of this functional, we calculate analytically the freezing parameters of the latter. We demonstrate explicitly that the stable crystals feature a lattice constant that is independent of density and whose value is dictated by the position of the negative minimum of the Fourier transform of the pair potential. This property is equivalent with the existence of clusters, whose population scales proportionally to the density. We establish that regardless of the form of the interaction potential and of the location on the freezing line, all cluster crystals have a universal Lindemann ratio L = 0.189 at freezing. We further make an explicit link between the aforementioned density functional and the harmonic theory of crystals. This allows us to establish an equivalence between the emergence of clusters and the existence of negative Fourier components of the interaction potential. Finally, we make a connection between the class of models at hand and the system of infinite-dimensional hard spheres, when the limits of interaction steepness and space dimension are both taken to infinity in a particularly described fashion.
