Integrated Approaches for Urban Transformation
Creators: name: Ahmed, Mejbahuddin
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: The shift in cultural matrix distorted the historic city while Dhaka lost its topographical and hydrological
character due to the increasing demand for transformation of land for urban uses. Instead of safeguarding,
the politico-bureaucracy distorted and closed Dhaka's major public open spaces to erase the associated
historical meanings and restricted access to urban space for the majority who struggle to survive along the
poverty line. As the state of adventurer's capitalism marked by the impulse of acquisition through exploitation of political or bureaucratic opportunities degraded land into mere property accessible to a few; Dhaka failed to transform into a place of opportunity for all.
Thus, Dhaka failed to address the issues of social integration and to create a visible structure of its cultural identity. Instead of clearing the confusions intrinsic of long foreign rules and reestablishing a cultural identity that belongs to the land and its people, the political parties preferred to exploit the distortions inflicted by separation of pragmatic and mythical space and continued use of religious symbols to their benefit. The broad objective of the thesis is to formulate guidelines and evaluation criteria for new projects so that they might help Dhaka to transform into a city that:
i. concretizes shared values and understandings,
ii. makes communal life possible and meaningful, and
iii. is inclusive and creates opportunities for growth and prosperity for the common people

description: We analyzed extensively the dynamics of polymer chains in solutions simulated with dissipative particle dynamics (DPD), with a special focus on the potential influence of a low Schmidt number of a typical DPD fluid on the simulated polymer dynamics. It has been argued that a low Schmidt number in a DPD fluid can lead to underdevelopment of the hydrodynamic interaction in polymer solutions. Our analyses reveal that equilibrium polymer dynamics in dilute solution, under a typical DPD simulation conditions, obey the Zimm model very well. With a further reduction in the Schmidt number, a deviation from the Zimm model to the Rouse model is observed. This implies that the hydrodynamic interaction between monomers is reasonably developed under typical conditions of a DPD simulation. Only when the Schmidt number is further reduced, the hydrodynamic interaction within the chains becomes underdeveloped. The screening of the hydrodynamic interaction and the excluded volume interaction as the polymer volume fraction is increased are well reproduced by the DPD simulations. The use of soft interaction between polymer beads and a low Schmidt number do not produce noticeable problems for the simulated dynamics at high concentrations, except that the entanglement effect which is not captured in the simulations.

description: We present the analysis of the colour-magnitude diagram (CMD) morphology of the ~ 800 Myr old star cluster NGC1831 in the Large Magellanic Cloud, exploiting deep, high-resolution photometry obtained using the Wide Field Camera 3 onboard the Hubble Space Telescope. We perform a simultaneous analysis of the wide upper main sequence and main sequence turn-off observed in the cluster, to verify whether these features are due to an extended star formation or a range of stellar rotation rates, or a combination of these two effects. Comparing the observed CMD with Monte Carlo simulations of synthetic stellar populations, we derive that the morphology of NGC1831 can be fully explained in the context of the rotation velocity scenario, under the assumption of a bimodal distribution for the rotating stars, with ~40% of stars being slow-rotators ($Ω$ / $Ω_{crit}$ < 0.5) and the remaining ~ 60% being fast rotators ($Ω$ / $Ω_{crit}$ > 0.9). We derive the dynamical properties of the cluster, calculating the present cluster mass and escape velocity, and predicting their past evolution starting at an age of 10 Myr. We find that NGC1831 has an escape velocity $v_{esc}$ = 18.4 km/s, at an age of 10 Myr, above the previously suggested threshold of 15 km/s, below which the cluster cannot retain the material needed to create second-generation stars. These results, combined with those obtained from the CMD morphology analysis, indicate that for the clusters whose morphology cannot be easily explained only in the context of the rotation velocity scenario, the threshold limit should be at least ~ 20 km/s.

Relic gravitons and viscous cosmologies

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Previously it was shown that there exists a class of viscous cosmological models which violate the dominant energy condition for a limited amount of time after which they are smoothly connected to the ordinary radiation era (which preserves the dominant energy conditions). This violation of the dominant energy condition at an early cosmological epoch may influence the slopes of energy spectra of relic gravitons that might be of experimental relevance. However, the bulk viscosity coefficient of these cosmologies became negative during the ordinary radiation era, and then the entropy of the sources driving the geometry decreases with time. We show that in the presence of viscous sources with a linear barotropic equation of state $p=γρ$ we get viscous cosmological models with positive bulk viscous stress during all their evolution, and hence the matter entropy increases with the expansion time. In other words, in the framework of viscous cosmologies, there exist isotropic models compatible with the standard second law of thermodynamics which also may influence the slopes of energy spectra of relic gravitons.

description: In recent years, unmanned aircraft systems (UASs) are frequently used in many different applications of photogrammetry such as building damage monitoring, archaeological mapping and vegetation monitoring. In this paper, a new state-of-the-art vertical take-off and landing fixed-wing UAS is proposed to robust photogrammetry missions, called SAMA-VTOL. In this study, the capability of SAMA-VTOL is investigated for generating orthophoto. The major stages are including designing, building and experimental scenario. First, a brief description of design and build is introduced. Next, an experiment was done to generate accurate orthophoto with minimum ground control points requirements. The processing step, which includes automatic aerial triangulation with camera calibration and model generation. In this regard, the Pix4Dmapper software was used to orientate the images, produce point clouds, creating digital surface model and generating orthophoto mosaic. Experimental results based on the test area covering 26.3 hectares indicate that our SAMA-VTOL performs well in the orthophoto mosaic task.

Coherent X-rays with Tunable Time-Dependent Polarization

description: We describe a method for producing high power, coherent x-ray pulses from a free electron laser with femtosecond scale periodic temporal modulation of the polarization vector. This approach relies on the generation of a temporal intensity modulation after self seeding either by modulating the seed intensity or the beam current. After generating a coherent temporally modulated $s$-polarization pulse, the electron beam is delayed by half a modulation period and sent into a short orthogonally oriented undulator, serving as a $p$-polarization afterburner. We provide simulations of three configurations for realizing this polarization switching, namely, enhanced self seeding with an intensity modulation generated by 2 color self seeding, enhanced self seeding of a current modulated bunch, and regular self seeding of a current modulated bunch. Start to end simulations for the Linac Coherent Light Source-II are provided for the latter.

description: The spin- and charge-density-wave order parameters of the itinerant antiferromagnet chromium are measured directly with non-resonant x-ray diffraction as the system is driven towards its quantum critical point with high pressure using a diamond anvil cell. The exponential decrease of the spin and charge diffraction intensities with pressure confirms the harmonic scaling of spin and charge, while the evolution of the incommensurate ordering vector provides important insight into the difference between pressure and chemical doping as means of driving quantum phase transitions. Measurement of the charge density wave over more than two orders of magnitude of diffraction intensity provides the clearest demonstration to date of a weakly-coupled, BCS-like ground state. Evidence for the coexistence of this weakly-coupled ground state with high-energy excitations and pseudogap formation above the ordering temperature in chromium, the charge-ordered perovskite manganites, and the blue bronzes, among other such systems, raises fundamental questions about the distinctions between weak and strong coupling.

description: Labyrinth chaos was discovered by Otto Rössler and René Thomas in their endeavour to identify the necessary mathematical conditions for the appearance of chaotic and hyperchaotic motion in continuous flows. Here, we celebrate their discovery by considering a single labyrinth walks system and an array of coupled labyrinth chaos systems that exhibit complex, chaotic behaviour, reminiscent of chimera-like states, a peculiar synchronisation phenomenon. We discuss the properties of the single labyrinth walks system and review the ability of coupled labyrinth chaos systems to exhibit chimera-like states due to the unique properties of their space-filling, chaotic trajectories, what amounts to elegant, hyperchaotic walks. Finally, we discuss further implications in relation to the labyrinth walks system by showing that even though it is volume-preserving, it is not force-conservative.

description: We have investigated the temperature-dependent changes in the near-$E$$_F$ occupied and unoccupied states of Pr$_{0.67}$Ca$_{0.33}$MnO$_3$ which shows the presence of ferromagnetic and antiferromagnetic phases. The temperature-dependent changes in the charge and orbital degrees of freedom and associated changes in the Mn 3$d$ - O 2$p$ hybridization result in varied O 2$p$ contributions to the valence band. A quantitative estimate of the charge transfer energy ($E$$_{CT}$) shows a larger value compared to the earlier reported estimates. The charge localization causing the large $E$$_{CT}$ is discussed in terms of different models including the electronic phase separation.

description: The extensive prehistoric landscapes of the western and southern fen edge have, for many years, dominated the archaeology of the Early-Middle Bronze Age in the region. However, within the last decade, large-scale excavations to the south of Cambridge particularly have revealed extensive Bronze Age remains that are redressing this previous geographical bias. Recent evidence from the new Marleigh development, near Fen Ditton, excavated between 2015 and 2018, provides an important addition to a growing corpus of southern Cambridgeshire sites and an opportunity to further enhance our understanding of Bronze Age activity in the region. This paper presents the results of the excavation of two Early Bronze Age funerary monuments and a Middle Bronze Age enclosed settlement recorded amongst later Iron Age and Early Roman settlement remains at the High Ditch Road site.

description: Motivated by recent experimental observations, we study theoretically multiple bright solitary waves of trapped Bose-Einstein condensates. Through variational and numerical analyses, we determine the threshold for collapse of these states. Under $π$-phase differences between adjacent waves, we show that the experimental states lie consistently at the threshold for collapse, where the corresponding in-phase states are highly unstable. Following the observation of two long-lived solitary waves in a trap, we perform detailed three-dimensional simulations which confirm that in-phase waves undergo collapse while a $π$-phase difference preserves the long-lived dynamics and gives excellent quantitative agreement with experiment. Furthermore, intermediate phase differences lead to the growth of population asymmetries between the waves, which ultimately triggers collapse.

description: The cascading 3.21 MeV and 4.44 MeV electric quadrupole transitions have been observed from the Hoyle state at 7.65 MeV excitation energy in $^{12}$C, excited by the $^{12}$C(p,p$^{\prime}$) reaction at 10.7 MeV proton energy. From the proton-$γ$-$γ$ triple coincidence data, a value of ${Γ_{\rm rad}}/Γ=6.2(6) \times 10^{-4}$ was obtained for the radiative branching ratio. Using our results, together with ${Γ_π^{E0}}/Γ$ from Eriksen et al., Phys. Rev. C 102, 024320 and the currently adopted $Γ_π(E0)$ values, the radiative width of the Hoyle state is determined as $Γ_{\rm rad}=5.1(6) \times 10^{-3}$ eV. This value is about 34% higher than the currently adopted value and will impact on models of stellar evolution and nucleosynthesis.

Life history and population dynamics of western flower thrips, Frankliniella Occidentalis (Pergande) (Thysanoptera:Thripidae) in Nectarine Orchards in the Dry Central Interior, British Columbia
Creators: name: Pearsall, Isobel A.
Publisher: name: University of British Columbia

description: Nectarine production in the Dry Central Interior, British Columbia, has recently grown in status from a minor specialty crop to a regular commodity. However, this developing industry is threatened by the damage done by the western flower thrips (WFT), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), an insect showing high levels of insecticide resistance and apparently without effective natural enemies in this crop. This three-year study involved an examination of WFT biology, habitat, dispersal, and behaviour in nectarine orchards in the Okanagan and Similkameen valleys. The aim was to identify stages in the life cycle where a control effort could be focused and to aid in creating an appropriate pest management program for thrips. Emergence and immigration into orchards were gradual and widespread processes. Egg-laying also occurred over an extended period of time, but with the bulk of eggs laid early in the development of nectarine buds, which is much earlier than prior studies had suggested. The lack of peak periods for these activities hinders control. Feeding by first generation larvae was identified as the primary cause of russetting damage to nectarine fruit. Direct bud sampling was found to more efficient than using sticky cards to trap adult WFT. However, neither adult counts from sticky cards nor buds allowed me to predict either future larval or damage levels which makes it difficult to produce damage thresholds for this insect on this crop. WFT tended to move into orchards from the direction of patches of wild land, but moved out of orchards in accordance with the dominant wind patterns. Immigration occurred mainly at ground level in the early spring. Flower preference studies suggested that exploitation of this flight behaviour by using a trap crop that blooms in the early spring is unlikely to succeed. Orchards located adjacent to tracts of wild land appeared to be most at risk for immigration of WFT in early spring, and showed higher incidence of damaged fruit than orchards that are surrounded, and thus protected, by other orchards. Careful choice of planting sites appears to be one of the only control options available at present.

description: Archaeological excavations at the former CEMEX Cement Works, Barrington, revealed evidence for an Iron Age settlement dating to between c. 400 and 200 cal. BC. A variety of domestic archaeological features, including storage pits, numerous cooking pits, probable clay extraction pits for making daub, a waterhole, and at least six four-post structures were excavated. Within some of the storage pits was evidence for so-called 'special' deposition of both animal bone (including a complete calf skeleton) and disarticulated and cremated human bone. Part of what may have been an extensive system of rectilinearly organised (co-axial) ditches appears to pre-date most of the Iron Age pits and is thought likely to have origins in the Middle Bronze Age. Significantly, it appears that this field system was still a visible and, in part, still-maintained aspect of the local landscape into the Middle Iron Age.

description: We present the results of seven years of K-band monitoring of the low-mass X-ray binary GRS 1915+105. Positive correlations between the infrared flux and the X-ray flux and X-ray hardness are demonstrated. Analysis of the frequency spectrum shows that the orbital period of the system is $P_{orb}= 30.8 \pm 0.2$ days. The phase and amplitude of the orbital modulation suggests that the modulation is due to the heating of the face of the secondary star. We also report another periodic signature between 31.2 and 31.6 days, most likely due to a superhump resonance. From the superhump period we then obtain a range on the mass ratio of the system, $0.05 < q < 0.12$.

Moreover, more detailed characterizations are obtained with experimentally feasible spatially resolved counting distributions.

Josephson effect due to the long-range odd-frequency triplet superconductivity in SFS junctions with Neel domain walls

description: We consider a SFS Josephson junction made of two superconductors S and a multidomain ferromagnet F with an in-plane magnetization. We assume that the neighboring domains of the ferromagnet are separated by Neel domain walls. An odd-frequency triplet long-range component of superconducting correlations arises in the domain walls and spreads into the domains over a long distance of the order $ξ_T = \sqrt{D / 2 πT}$, where $D$ is the diffusion coefficient (dirty limit is implied). We calculate the contribution of this component to the Josephson current in the situation when conventional short-range components exponentially decay over the thickness of the F layer and can be neglected. In the limit when the thickness of the F layer is much smaller than the penetration length of the long-range component, we find that the junction is in the $π$ state. We also analyze a correction to the density of states due to the long-range triplet component.

description: The analytical expressions of liquid-vapor macroscopic contact angles are analyzed for various simple geometries and arrangements of the substrate, in particular when the latter exhibits two or more scales. It concerns the Wenzel state of wetting when the substrate is completely wet, the Cassie-Baxter state when the liquid hangs over the substrate, but also intermediate states of wetting which are shown to be relevant and in competition with the two other ones. Under a separation of scales hypothesis, a composition rule of contact angles is developed whose interest is illustrated in a close packing setup of rasperry-like particles.

GEI-16 : a novel component of the C. elegans fibrous organelle

description: Animal tissues are maintained by the correct cell-cell contacts and cellular shape. Cell shape and associations are governed by the combined action of the filament cytoskeleton in association with adhesion complexes. Desmosomes and hemidesmosomes are one such class of adhesion complex. From worms to humans epithelial tissues are flattened and made resistant to mechanical stress by desmosomes and hemidesmosomes. These membrane-associated junction complexes are attached to the intermediate filaments (IFs), the strongest and most elastic of the cytoskeletal filaments. In Caenorhabditis elegans, a requirement for the hemidesmosomes first becomes apparent in embryonic morphogenesis. Without functioning hemidesmosomes elongation arrests at the two-fold stage and the embryo never attains its vermiform shape (four-fold elongation). Characterisation of the loss of larva-specific intermediate filaments has shown that functional hemidesmosomes are necessary for tissue integrity and the continued development of the worm at all stages. It appears that, as in other animals, hemidesmosomes maintain a squamified epithelium which resists and equalises shearing forces generated during morphogenetic and locomotive movement. This thesis discusses the discovery of GEI-16 (PAT-12), a new component of the hemidesmosome and fibrous organelle (FO) in C. elegans. Discovered in a screen for uncharacterised, pan-nematode genes with vital functions, GEI-16 is necessary for all life stages. Loss of gei-16 leads to paralysis, muscle detachment and developmental arrest during the elongation step of embryogenesis. The same phenotype occurs in all stages of development if gei-16 is lacking. GEI-16 is likely to function with VAB-10 and the actin cytoskeleton to organise and strengthen the fibrous organelle during elongation.

description: Unlike in the Schwarzschild black hole background, gravitational perturbations in a Kerr black hole background can not be decomposed into simple tensor harmonics in the time domain. Here, we make mode decompositions only in the azimuthal direction. As a first step, we discuss the resulting (2+1)-dimensional Klein-Gordon differential equation for scalar perturbations with a two dimensional Dirac's $δ$-function as a source representing a point particle orbiting a much larger black hole. To make this equation amenable for numerical integrations we explicitly remove analytically the singular behavior of the source and compute a global, well bahaved, effective source for the corresponding waveform.

description: Excitonic insulator (EI) is an intriguing insulating phase of matter, where electrons and holes are bonded into pairs, so called excitons, and form a phase-coherent state via Bose-Einstein Condensation (BEC). Its theoretical concept has been proposed several decades ago, but the followed research is very limited, due to the rare occurrence of EI in natural materials and the lack of manipulating method of excitonic condensation. In this paper, we report the realization of a doping-controlled EI-to-semi-metal transition in Ta$_2$NiSe$_5$ using $in$-$situ$ potassium deposition. Combining with angle-resolved photoemission spectroscopy (ARPES), we delineate the evolution of electronic structure through the EI transition with unprecedented precision. The results not only show that Ta$ _2 $NiSe$ _5 $ (TNS) is an EI originated from a semi-metal non-interacting band structure, but also resolve two sequential transitions, which could be attributed to the phase-decoherence and pair-breaking respectively. Our results unveil the Bardeen-Cooper-Schrieffer (BCS)-BEC crossover behavior of TNS and demonstrate that its band structure and excitonic binding energy can be tuned precisely via alkali-metal deposition. This paves a way for investigations of BCS-BEC crossover phenomena, which could provide insights into the many-body physics in condensed matters and other many-body systems.

description: The National Trust estate at Wimpole in south-west Cambridgeshire is famous for its 17th-century house, extensive landscape gardens and parkland. However, archaeological excavations on the estate at Lamp Hill revealed the site's early history in the form of a Late Iron Age/Conquest period farmstead with significant and unusual characteristics. Principal amongst the discoveries were distinctive groups of artefacts, including brooches, coins, items with a military association and votives. Particularly notable is a copper-alloy spatula handle of a figure bearing a torc, possibly a Continental import. Links with the Roman army may explain how some of the finds reached the site, while the effects of the Boudican revolt may also be detected in the pre-Flavian date of much of the metalwork and, to a certain extent, the pottery.
Deep Q-Network-based Adaptive Alert Threshold Selection Policy for Payment Fraud Systems in Retail Banking

description: Machine learning models have widely been used in fraud detection systems. Most of the research and development efforts have been concentrated on improving the performance of the fraud scoring models. Yet, the downstream fraud alert systems still have limited to no model adoption and rely on manual steps. Alert systems are pervasively used across all payment channels in retail banking and play an important role in the overall fraud detection process. Current fraud detection systems end up with large numbers of dropped alerts due to their inability to account for the alert processing capacity. Ideally, alert threshold selection enables the system to maximize the fraud detection while balancing the upstream fraud scores and the available bandwidth of the alert processing teams. However, in practice, fixed thresholds that are used for their simplicity do not have this ability. In this paper, we propose an enhanced threshold selection policy for fraud alert systems. The proposed approach formulates the threshold selection as a sequential decision making problem and uses Deep Q-Network based reinforcement learning. Experimental results show that this adaptive approach outperforms the current static solutions by reducing the fraud losses as well as improving the operational efficiency of the alert system.

description: This research explores donor preferences as it relates to fundraising appeals and donor acknowledgement. The literature review outlined the challenges and opportunities in fundraising, donor characteristics and motivation, and the importance of donor relations in fundraising. An online questionnaire was developed to send to perspective donors who received an undergraduate degree from the same college. The results from the questionnaire revealed that the participants favored personalized fundraising solicitations and acknowledgements authored by a familiar college representative. In addition, interaction with those who benefit from the donor’s gift was highly rated, and identified as a favorable action to properly acknowledge and thank a donor for their gift.

description: Excavation in advance of construction of a house at Church End, Arrington, revealed part of a Middle to Late Anglo-Saxon settlement comprising three post-built buildings and associated pits set within a system of ditched enclosures. Finds and environmental evidence reflect domestic activity, with the range of handmade pottery, Middle Anglo-Saxon Ipswich and Southern Maxey-type wares, and Late Saxon St Neots ware suggesting occupation from the c. 8th/9th to 10th/11th centuries, continuing to around AD 1200. One of the pits contained a silver penny of King Æthelberht of Wessex (AD 858-864), thought to be the first coin of Æthelberht recorded from Cambridgeshire. The principal results of the project are described and contextualised and the implications for understanding of Arrington's development considered.

description: This collection contains written texts of surveys collected following World Color Survey (WCS) protocol, with the exception that unlike the WCS, speakers responded freely to the stimulus without restricting responses to basic color terms. (Two speakers in 2017 completed the task using a restricted set of color terms, strictly following the WCS protocol, but speakers struggled to provide any responses for a large number of chips, prompting the switch to the free-naming task method.) The survey was conducted with multilingual speakers of the languages Nafaanra, Twi, and English. There will ultimately be four basic language paradigms in this dataset varied on language used in task and participant multilingualism. The basic paradigms are:

Task language: Nafaanra; Participant: Multilingual (Twi and/or English)
Task language: Twi; Participant: Multilingual (Nafaanra and English)
Task language: Twi; Participant: Multilingual (English only)*
Task language: English; Participant: Multilingual (Nafaanra and/or Twi)

Currently available data include datasets collected in 2017 and 2018, both with multilingual Nafaanra speakers in Nafaanra. Twi and English data will be made available at a future date.

description: The purpose of this study was to determine the impact of small reading groups, independent reading, and partner reading on students’ reading levels from on-grade-level to above-grade- level. The participants of this study were six first grade students enrolled at an elementary school in Baltimore County. The participants were provided instruction from Baltimore County Public School English Language Arts curriculum as designed to align with the Common Core State Standards. In addition to this curriculum, treatment students received small group instruction, were required to complete thirty minutes of daily independent reading, and partner reading during independent work. The analysis revealed a significant increase in pre/post-test mean scores. Future research should continue in this area to determine methods of instruction to promote reading level growth to more complex text.

description: Existing denoising methods typically restore clear results by aggregating pixels from the noisy input. Instead of relying on hand-crafted aggregation schemes, we propose to explicitly learn this process with deep neural networks. We present a spatial pixel aggregation network and learn the pixel sampling and averaging strategies for image denoising. The proposed model naturally adapts to image structures and can effectively improve the denoised results. Furthermore, we develop a spatio-temporal pixel aggregation network for video denoising to efficiently sample pixels across the spatio-temporal space. Our method is able to solve the misalignment issues caused by large motion in dynamic scenes. In addition, we introduce a new regularization term for effectively training the proposed video denoising model. We present extensive analysis of the proposed method and demonstrate that our model performs favorably against the state-of-the-art image and video denoising approaches on both synthetic and real-world data.

description: The modern astrophysics is moving towards the enlarging of experiments and combining the channels for detecting the highest energy processes in the Universe. To obtain reliable data, the experiments should operate within several decades, which means that the data will be obtained and analyzed by several generations of physicists. Thus, for the stability of the experiments, it is necessary to properly maintain not only the data life cycle, but also the human aspects, for example, attracting, learning and continuity. To this end, an educational and outreach resource has been deployed in the framework of German-Russian Astroparticle Data Life Cycle Initiative (GRADLCI).
