description: Multi-modality is widely used in medical imaging, because it can provide multiinformation about a target (tumor, organ or tissue). Segmentation using multimodality consists of fusing multi-information to improve the segmentation. Recently, deep learning-based approaches have presented the state-of-the-art performance in image classification, segmentation, object detection and tracking tasks. Due to their self-learning and generalization ability over large amounts of data, deep learning recently has also gained great interest in multi-modal medical image segmentation. In this paper, we give an overview of deep learning-based approaches for multi-modal medical image segmentation task. Firstly, we introduce the general principle of deep learning and multi-modal medical image segmentation. Secondly, we present different deep learning network architectures, then analyze their fusion strategies and compare their results. The earlier fusion is commonly used, since it's simple and it focuses on the subsequent segmentation network architecture. However, the later fusion gives more attention on fusion strategy to learn the complex relationship between different modalities. In general, compared to the earlier fusion, the later fusion can give more accurate result if the fusion method is effective enough. We also discuss some common problems in medical image segmentation. Finally, we summarize and provide some perspectives on the future research.

description: Relative entropy measures may be utilized as market rather than aggregate concentration measures, which presume no correspondence between the industry and markets. Since there are important structural categories of retail outlets within the food retailing industry, relative entropy measures applied to these categories for individual metropolitan markets offer a more refined quantification of concentration propensities than other, more traditional, concentration measures.

description: We analyse multi-wavelength Hubble Space Telescope (HST) observations of a large number of star clusters in the nearby (post-) starburst dwarf galaxy NGC 1569. Their spectral energy distributions (SEDs) cover at least the wavelength range from U to I in equivalent HST filters, in most cases supplemented by near-infrared data. Using our most up-to-date evolutionary synthesis models of the Goettingen GALEV code we determine ages, metallicities, extinction values and masses for each individual cluster robustly and independently. We confirm the youth of most of these objects. The majority were formed in a very intense starburst starting around 25 Myr ago. While there are two prominent ``super star clusters'' present in this galaxy, with masses of (5-16) * 10^5 Msun, almost all remaining clusters are significantly less massive than an average Milky Way globular cluster, and are generally consistent with open cluster-type objects. We determine the cluster mass function from individual cluster masses derived by scaling the model SEDs of known mass to the observed cluster SEDs for each individual cluster. We find signs of a change in the cluster mass function as the burst proceeds, which we attribute to the special conditions of star cluster formation in this starburst dwarf galaxy environment.

title: Medial Dorsal Thalamic Lesions and Working Memory in the Rat
Creators: name: Hunt, Peter Richard
Publisher: name: The Open University
Year: 1991

description: Pigmented rats of the DA strain with either radio frequency or ibotenic acid lesions of the thalamic nucleus medialis dorsalis were postoperatively given non-spatial and spatial tests of working memory. In the non-spatial task, delayed non-matching to sample, rats with both types of thalamic lesions showed acquisition impairmnts. The subgroup of rats with nucleus medialis dorsalis lesions that were able to reach the acquisition criterion did, however, perform normally when the retention interval was extended to 60 seconds and when proactive interference was increased. A final, control variant of this task was included to address the possibility of a sensory deficit. In the spatial task, delayed forced alternation, rats were tested with differing retention intervals and with both spaced and massed trials. Damage to nucleus medialis dorsalis had no effect on acquisition or on spaced trials, but a slight deficit was found in the animals with radio frequency lesions under the massed trial condition. Much clearer deficits were, however, present in those animals in which the lesion extended appreciably into the anterior thalamic nuclei. The findings indicate that while cellular damage to nucleus medialis dorsalis may disrupt learning, some impairments in tests of spatial working memory attributed to this nucleus may reflect damage to the adjacent anterior thalamic nuclei.

description: GeSn alloys are the most promising semiconductors for light emitters entirely based on group IV elements. Alloys containing more than 8 at.% Sn have fundamental direct band-gaps, similar to conventional III-V semiconductors and thus can be employed for light emitting devices. Here, we report on GeSn microdisk lasers encapsulated with a SiNx stressor layer to produce tensile strain. A 300nm GeSn layer with 5.4 at.% Sn, which is an indirect band-gap semiconductor as-grown with a compressive strain of -0.32 %, is transformed via tensile strain engineering into a truly direct band-gap semiconductor. In this approach the low Sn concentration enables improved defect engineering and the tensile strain delivers a low density of states at the valence band edge, which is the light hole band. Continuous wave (cw) as well as pulsed lasing are observed at very low optical pump powers. Lasers with emission wavelength of 2.5 um have thresholds as low as 0.8kWcm^-2 for ns-pulsed excitation, and 1.1kWcm^-2 under cw excitation. These thresholds are more than two orders of magnitude lower than those previously reported for bulk GeSn lasers, approaching these values obtained for III-V lasers on Si. The present results demonstrate the feasabiliy and are the guideline for monolithically integrated Si-based laser sources on Si photonics platform.

description: Η παρούσα διπλωματική εργασία πραγματεύεται την εκτίμηση της σεισμικής επικινδυνότητας και σεισμικής διακινδύνευσης της πόλης της Λεμεσού. Συγκεκριμένα, μελετήθηκαν δύο διαφορετικές περιοχές, το Ιστορικό κέντρο της Λεμεσού και όλη η επαρχία Λεμεσού, και στις δύο περιπτώσεις οι αναλύσεις έγιναν για δύο σεισμικά σενάρια. Τα σεισμικά σενάρια αυτά, είναι ο σεισμός του 1996, που έγινε στα ανοικτά της Πάφου και ήταν πολύ κοντά στην στεριά, και ο σεισμός του 1999, που έγινε σε μια ημιορεινή περιοχή του νησιού και συγκεκριμένο στο ρήγμα της Γεράσας. Ο πρώτος σεισμός ήταν μεγέθους Μ=6.8 και ο δεύτερος ήταν μεγέθους Μ=5.2. Για να γίνουν οι αναλύσεις, σε κάθε περίπτωση αναπτύχθηκε ένα μοντέλο με τα στοιχεία υπό διακινδύνευση, στο οποίο αναφέρονται δεδομένα για το κτηριακό απόθεμα. Η ταξινόμηση των κτηρίων σε κατηγορίες τρωτότητας έγινε βάσει των τυπολογιών που προτείνει η ερευνητική κοινότητα GEM. Για να γίνουν οι αναλύσεις χρησιμοποιήθηκαν οι καμπύλες τρωτότητας που προτείνει η ερευνητική κοινότητα GEM. Έτσι έγιναν οι αναλύσεις για τη σεισμική επικινδυνότητα και σεισμική διακινδύνευση των περιοχών για τους δύο σεισμούς, και στη συνέχεια έγινε εξαγωγή των αποτελεσμάτων σε μορφή διαγραμμάτων και χαρτών. Τέλος έγινε περιγραφή και σύγκριση των αποτελεσμάτων από τις αναλύσεις μεταξύ τους και με τα δεδομένα που υπάρχουν από τις πραγματικές καταγραφές
description: The present diploma thesis examines the subject of seismic hazard and seismic risk of the city of Limassol. Specifically, two different areas were studied, the Historic center of Limassol and the entire city of Limassol, and for both cases the analyses were made for two seismic scenarios. These two seismic scenarios are, the earthquake of 1996, which occurred happened off Paphos and it was very close to the mainland, and the earthquake of 1999, which occurred in a semi-mountainous area of Cyprus and specifically in the Gerasas’ fault. The first earthquake was of magnitude M=6.8 and the second was of magnitude M=5.2. In order to make the analyses, in each case an exposure model with the data at risk was developed, including the buildings in the examined area. The buildings were classified into vulnerability categories according to the typologies proposed by the research community of GEM. In order to perform the analyses, the fragility and vulnerability curves proposed by GEM were used. Thus, the analyses for the seismic hazard and the hazard risk of the areas, for both earthquakes, were made, and then the results were exported in the form of diagrams and maps. Finally, the results of the analyses were described and compared with each other and with the data from the actual recordings

Upper critical field $H_{c2}$ calculations for the high critical temperature superconductors considering inhomogeneities

description: We perform calculations to obtain the $H_{c2}$ curve of high temperature superconductors (HTSC). We consider explicitly the fact that the HTSC possess intrinsic inhomogeneities by taking into account a non uniform charge density $ρ(r)$. The transition to a coherent superconducting phase at a critical temperature $T_c$ corresponds to a percolation threshold among different superconducting regions, each one characterized by a given $T_c(ρ(r))$. Within this model we calculate the upper critical field $H_{c2}$ by means of an average linearized Ginzburg-Landau (GL) equation to take into account the distribution of local superconducting temperatures $T_c(ρ(r))$. This approach explains some of the anomalies associated with $H_{c2}$ and why several properties like the Meissner and Nernst effects are detected at temperatures much higher than $T_c$.

Primary Care Management of the Elderly with Alzheimer’s Disease
Creators: name: Chan, Tsz Lune Viviane
Publisher: name: The University of British Columbia

description: The rising prevalence of Alzheimer’s disease (AD) in Canada demands practical and effective management of AD in the primary care setting. Currently, there is no curative treatment available for AD, which makes its management a challenging task. Therefore, this paper aims to consolidate evidence-based clinical recommendations from current literature for family nurse practitioners (FNPs) to implement when managing AD patients. In this literature review, 26 relevant journal articles from CINAHL Complete, MEDLINE with Full Text, and PubMed were examined. The literature review was guided by this question: What should F¬¬NPs include in their clinical checklist to provide the best evidence-based care when managing patients with AD? Based on the examined literature, 11 essential quality measures were recommended to be included in the clinical checklist, namely, goals and principles of care, dementia education, cognitive and functional status assessments, safety and driving counseling and assessments, nutrition and diet, pharmacological treatment for cognitive symptoms, behavioural and psychological symptoms and managament, concomitant conditions and management, caregiver support, advance care planning and palliative care, and lab and neuroimaging investigations. FNPs and specialists should also review these essential quality measures regularly during the course of disease. In conclusion, the management of AD requires multi-disciplinary involvement and FNPs should follow a systematic management approach when providing family-centred care for AD patients.

description: We examine sequences of dense packings of n congruent non-overlapping disks inside a square which follow specific patterns as n increases along certain values, n = n(1), n(2),... n(k),.... Extending and improving previous work of Nurmela and Ostergard where previous patterns for n = n(k) of the form k*k, k*k-1, k*k-3, k(k+1), and 4k*k+k were observed, we identify new patterns for n = k*k-2 and n = k*k+[k/2]. We also find denser packings than those in [Nurmela, Ostergard] for n =21, 28, 34, 40, 43, 44, 45, and 47. In addition, we produce what we conjecture to be optimal packings for n =51, 52, 54, 55, 56, 60, and 61. Finally, for each identified sequence n(1), n(2),... n(k),... which corresponds to some specific repeated pattern, we identify a threshold index k_0, for which the packing appears to be optimal for k =< k_0, but for which the packing is not optimal (or does not exist) for k > k_0.

description: The reversion of the time evolution of a quantum state can be achieved by changing the sign of the Hamiltonian as in the polarization echo experiment in NMR. In this work we describe an alternative mechanism inspired by the acoustic time reversal mirror. By solving the inverse time problem in a discrete space we develop a new procedure, the perfect inverse filter. It achieves the exact time reversion in a given region by reinjecting a prescribed wave function at its periphery.

description: We use fast periodic control to realize finite-time Otto cycles exhibiting quantum advantage. Such periodic modulation of the working medium - bath interaction Hamiltonian during the thermalization strokes can give rise to non-Markovian anti-Zeno dynamics, and corresponding reduction in the thermalization times. Faster thermalization can in turn significantly enhance the power output in engines, or equivalently, the rate of refrigeration in refrigerators. This improvement in performance of dynamically controlled Otto thermal machines arises due to the time-energy uncertainty relation of quantum mechanics.

We address relevant physical issues such as the timescale for the initial core collapse, the total energy emitted in neutrinos and their effect on the low density matter surrounding the core. We find that it is feasible that the neutrino burst can lead to significant mass ejection of the nuclear envelope.

This study aimed to validate rapid methods to detect Salmonella spp. from poultry samples. 2. A DNA isothermal amplification method, previously developed for other matrices, was applied for the specific detection of Salmonella spp. from various samples, including poultry tissues, drag and boot swabs, faeces and feed. A new procedure was validated with Salmonella spp. serotypes and isolates from other enteric bacterial species, as well as naturally contaminated poultry samples. 3. The study demonstrated the successful development and implementation of a procedure, including a DNA isothermal amplification method, for the detection of Salmonella spp. directly from tissues, drag and boot swabs, faeces and feed. The whole procedure can be performed in less than 24 hours and it has been successfully used in a veterinary diagnostic laboratory.

description: While quantum dots are at the forefront of quantum device technology, tuning multi-dot systems requires a lengthy experimental process as multiple parameters need to be accurately controlled. This process becomes increasingly time-consuming and difficult to perform manually as the devices become more complex and the number of tuning parameters grows. In this work, we present a crucial step towards automated tuning of quantum dot qubits. We introduce an algorithm driven by machine learning that uses a small number of coarse-grained measurements as its input and tunes the quantum dot system into a pre-selected charge state. We train and test our algorithm on a GaAs double quantum dot device and we consistently arrive at the desired state or its immediate neighborhood.

The essential features incorporated into the model are the anisotropic elasticity of the rods and the random geometry of the network. We show that there are three distinct scaling regimes, characterized by two distinct length scales on the elastic backbone. In addition to a critical rigidiy percolation region and a homogeneously elastic regime we find a novel intermediate scaling regime, where elasticity is dominated by bending deformations.

This research examines the tensile characteristics of jute composites and study was completed using UTM. When the epoxy matrix is reinforced its mechanical, qualities improved. In comparison to artificial fibers, jute fiber offers better qualities throughout the composite sector. As part of this research, composites have been manufactured using hand layup procedure. Jute fibers accounted for a volume proportion of 30% in all instances and (Graphene+MWCNT) is in varying proportions. Experimental data were compared to determine the tensile properties of the composites that had been created. It has been shown that the qualities of all the created composites are highly influenced by the reinforcing material’s tensile characteristics. No. of Pages : 14 No. of Claims : 9

description: A new site percolation model, directed spiral percolation (DSP), under both directional and rotational (spiral) constraints is studied numerically on the square lattice. The critical percolation threshold $p_c\approx 0.655$ is found between the directed and spiral percolation thresholds. Infinite percolation clusters are fractals of dimension $d_f\approx 1.733$. The clusters generated are anisotropic. Due to the rotational constraint, the cluster growth is deviated from that expected due to the directional constraint. Connectivity lengths, one along the elongation of the cluster and the other perpendicular to it, diverge as $p\to p_c$ with different critical exponents. The clusters are less anisotropic than the directed percolation clusters. Different moments of the cluster size distribution $P_s(p)$ show power law behavior with $|p-p_c|$ in the critical regime with appropriate critical exponents. The values of the critical exponents are estimated and found to be very different from those obtained in other percolation models. The proposed DSP model thus belongs to a new universality class. A scaling theory has been developed for the cluster related quantities. The critical exponents satisfy the scaling relations including the hyperscaling which is violated in directed percolation. A reasonable data collapse is observed in favour of the assumed scaling function form of $P_s(p)$. The results obtained are in good agreement with other model calculations.

Publisher: name: Unknown
Year: 2010
Subjects: Community/Rural/Urban Development

description: The rural areas of Benue State are inhabited by the bulk of the population. They serve as the base for the production of food and fiber and principal market for domestic manufactures. This relevance informed the government to adopt several strategies in the past to transform the sector. This paper examines the series of efforts made by successive administrations to develop the rural areas. The rural people have decided to form community based organizations (CBOs) as a strategy for survival. This paper therefore examines the nature, activities and impact of the CBOs on rural life and environment. The author advocates that; the government should adopt and utilize the CBOs as a national strategy for a rural development since they have worked well for the rural populace but failed to develop the sector due to certain constraints.

Numerical simulation of a possible counterexample to cosmic censorship

description: A numerical simulation is presented here of the evolution of initial data of the kind that was conjectured by Hertog, Horowitz and Maeda to be a violation of cosmic censorship. That initial data is essentially a thick domain wall connecting two regions of anti-deSitter space. The initial data has a free parameter that is the initial size of the wall. The simulation shows no violation of cosmic censorship, but rather the formation of a small black hole. The simulation described here is for a moderate wall size and leaves open the possibility that cosmic censorship might be violated for larger walls.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: A grand-canonical system of interacting bosons is considered to study phase transitions of ultracold atoms in an optical lattice. The phase diagram is discussed in terms of a matrix-like order parameter, representing a symmetric phase (Mott insulator) and a symmetry-broken phase (Bose-Einstein condensate). An exact solution was found by introducing $N$ colors and taking the limit $N\to\infty$.

Carrier relaxation in GaAs v-groove quantum wires and the effects of localization

description: Carrier relaxation processes have been investigated in GaAs/AlGaAs v-groove quantum wires (QWRs) with a large subband separation (46 meV). Signatures of inhibited carrier relaxation mechanisms are seen in temperature-dependent photoluminescence (PL) and photoluminescence-excitation (PLE) measurements; we observe strong emission from the first excited state of the QWR below ~50 K. This is attributed to reduced inter-subband relaxation via phonon scattering between localized states. Theoretical calculations and experimental results indicate that the pinch-off regions, which provide additional two-dimensional confinement for the QWR structure, have a blocking effect on relaxation mechanisms for certain structures within the v-groove. Time-resolved PL measurements show that efficient carrier relaxation from excited QWR states into the ground state, occurs only at temperatures > 30 K. Values for the low temperature radiative lifetimes of the ground- and first excited-state excitons have been obtained (340 ps and 160 ps respectively), and their corresponding localization lengths along the wire estimated.

Stable embedded solitons

Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: Stable embedded solitons are discovered in the generalized third-order nonlinear Schroedinger equation. When this equation can be reduced to a perturbed complex modified KdV equation, we developed a soliton perturbation theory which shows that a continuous family of sech-shaped embedded solitons exist and are nonlinearly stable. These analytical results are confirmed by our numerical simulations. These results establish that, contrary to previous beliefs, embedded solitons can be robust despite being in resonance with the linear spectrum.

59Co-NMR Knight Shift of the Superconducting NaxCoO2.yH2O

description: Layered Co oxide NaxCoO2.yH2O with the superconducting transition temperature Tc =4.5 K has been studied by 59Co-NMR. The Knight shift K estimated from the observed spectra for powder sample exhibits almost temperature(T)-independent behavior above Tc and decreases with decreasing T below Tc. This result and the existence of the coherence peak in the spin-lattice-relaxation-rate versus T curve reported by the present authors indicate, naively speaking, that the singlet order parameter with s-wave symmetry is realized in NaxCoO2.yH2O. Differences of the observed behaviors between the spectra of the non-aligned sample and the one aligned in epoxy adhesive by applying the external magnetic field are discussed.

description: New high resolution CO(3-2) interferometric map of the IR-bright interacting galaxy system VV114 observed with the Submillimeter Array (SMA) reveal a substantial amount of warm and dense gas in the IR-bright but optically obscured galaxy, VV114E, and the overlap region connecting the two nuclei. A 1.8 x 1.4 kpc concentration of CO(3-2) emitting gas with a total mass of 4 x 10^9 Msun coincides with the peaks of NIR, MIR, and radio continuum emission found previously by others, identifying the dense fuel for the AGN and/or the starburst activity there. Extensive CO(2-1) emission is also detected, revealing detailed distribution and kinematics that are consistent with the earlier CO(1-0) results. The widely distributed molecular gas traced in CO(2-1) and the distributed discrete peaks of CO(3-2) emission suggest that a spatially extended intense starbursts may contribute significantly to its large IR luminosity. These new observations further support the notion that VV114 is approaching its final stage of merger, when violent central inflow of gas triggers intense starburst activity possibly boosting the IR luminosity above the ultraluminous threshold.
