description: Estimating 3D hand poses from a single RGB image is challenging because depth ambiguity leads the problem ill-posed. Training hand pose estimators with 3D hand mesh annotations and multi-view images often results in significant performance gains. However, existing multi-view datasets are relatively small with hand joints annotated by off-the-shelf trackers or automated through model predictions, both of which may be inaccurate and can introduce biases. Collecting a large-scale multi-view 3D hand pose images with accurate mesh and joint annotations is valuable but strenuous. In this paper, we design a spin match algorithm that enables a rigid mesh model matching with any target mesh ground truth. Based on the match algorithm, we propose an efficient pipeline to generate a large-scale multi-view hand mesh (MVHM) dataset with accurate 3D hand mesh and joint labels. We further present a multi-view hand pose estimation approach to verify that training a hand pose estimator with our generated dataset greatly enhances the performance. Experimental results show that our approach achieves the performance of 0.990 in $\text{AUC}_{\text{20-50}}$ on the MHP dataset compared to the previous state-of-the-art of 0.939 on this dataset.

description: We have used the NICMOS NIC1 camera on the Hubble Space Telescope to obtain high angular resolution images of 51 ultracool dwarfs in the immediate Solar Neighbourhood. Nine systems are resolved as binary, with component separations from 1.5 and 15 AU. All of the systems have components with similar luminosities, and, consequently, high mass ratios, q > 0.8. Limiting analysis to L dwarfs within 20 parsecs, the observed binary fraction is 12(+7/-3). Applying Bayesian analysis to our dataset, we derive a mass-ratio distribution that peaks strongly at unity. Modelling the semi-major axis distribution as a logarithmic Gaussian, the best fit is centered at log(a_0) = 0.8 AU (~6.3 AU), with a (logarithmic) width of 0.3. The current data are consistent with an overall binary frequency of ~24%.

description: We present a hydrodynamic theory to describe a chiral electron system with a Weyl spin-orbit interaction on a field-theoretic basis. Evaluating the momentum flux density as a linear response to a driving electric field, we derive an equation of motion for the orbital angular momentum. It is shown that the chiral nature leads to a dynamic bulk angular momentum generation by inducing a global torque as a response to the applied field. The steady state angular momentum is calculated taking account of rotational viscosity.

description: High resolution spectroscopy with FUSE and STIS of atomic and molecular velocity stratification in the nebular outflow of M27 challenge models for the abundance kinematics in planetary nebulae. The simple picture of a very high speed (~ 1000 km/s), high ionization, radiation driven stellar wind surrounded by a slower (~ 10 km/s) mostly molecular outflow, with low ionization and neutral atomic species residing at the wind interaction interface, is not supported... We find ...there is a fast (33 -- 65 km/s) low ionization zone, surrounding a slower ( H_2^+ + e -> H(1s) + H (nl)), which ultimately produces fluorescence of Ha and Lya. In the optically thin limit at the inferred radius of the velocity transition we find dissociation of H_2 by stellar Lyc photons is an order of magnitude more efficient than spontaneous dissociation by far-UV photons. We suggest that the importance of this H_2 destruction process in HII regions has been overlooked.

description: SL(2,Z) duality transformations in asymptotically AdS4 x S^7 act non-trivially on the three-dimensional SCFT of coincident M2-branes on the boundary. We show how S-duality acts away from the IR fixed point. We develop a systematic method to holographically obtain the deformations of the boundary CFT and show how electric-magnetic duality relates different deformations. We analyze in detail marginal deformations and deformations by dimension 4 operators. In the case of massive deformations, the RG flow relates S-dual CFT's. Correlation functions in the CFT are computed by varying magnetic bulk sources, whereas correlation functions in the dual CFT are computed by electric bulk sources. Under massive deformations, the boundary effective action is generically minimized by massive self-dual configurations of the U(1) gauge field. We show that a self-dual choice of boundary conditions exists, and it corresponds to the self-dual topologically massive gauge theory in 2+1 dimensions. Thus, self-duality in three dimensions can be understood as a consequence of electric-magnetic invariance in the bulk of AdS4.

description: Theoretical treatments of frictional granular matter often assume that it is legitimate to invoke classical elastic theory to describe its coarse-grained mechanical properties. Here we show, based on experiments and numerical simulations, that this is generically not the case since stress auto-correlation functions decay more slowly than the elastic Green's function. It was shown theoretically that standard elastic decay demands pressure and torque density fluctuations to be normal, with possibly one of them being hyperuniform. Generic compressed frictional assemblies exhibit however abnormal pressure fluctuations, failing to conform with the central limit theorem. The physics of this failure is linked to correlations built in the material during compression from a dilute configuration prior to jamming. By changing the protocol of compression one can observe different pressure fluctuations and stress auto-correlations decay at large scales.

description: We describe IRAC 3.6-8 mu_m observations and ground-based near-IR JHKs photometry from Mimir and 2MASS of the massive double cluster h & chi Persei complete to J=15.5 (M ~ 1.3 Msun. Within 25' of the cluster centers we detect \~11,000 sources with J < 15.5, ~7,000 sources with [4.5] < 15, and ~ 5000 sources with [8] < 14.5. In both clusters, the surface density profiles derived from the 2MASS data decline with distance from the cluster centers as expected for a bound cluster. Within 15' of the cluster centers, ~ 50% of the stars lie on a reddened ~ 13 Myr isochrone; at 15'-25' from the cluster centers, ~ 40% lie on this isochrone. Thus, the optical/2MASS color-magnitude diagrams indicate that h & chi Per are accompanied by a halo population with roughly the same age and distance as the two dense clusters. The double cluster lacks any clear IR excess sources for J < 13.5 (~ 2.7 Msun). Therefore, disks around high-mass stars disperse prior to ~ 10^{7} yr. At least 2-3% of the fainter cluster stars have strong IR excess at both [5.8] and [8]. About 4-8% of sources slightly more massive than the Sun (~ 1.4 Msun) have IR excesses at [8]. Combined with the lack of detectable excesses for brighter stars, this result suggests that disks around lower-mass stars have longer lifetimes. The IR excess population also appears to be larger at longer IRAC bands ([5.8], [8]) than at shorter IRAC/2MASS bands ($K_{s}$, [4.5]), a result consistent with an inside-out clearing of disks.

A Novel Idea Generation Tool using a Structured Conversational AI (CAI) System

description: This paper presents a novel conversational AI-enabled active ideation interface as a creative idea-generation tool to assist novice designers in mitigating the initial latency and ideation bottlenecks that are commonly observed. It is a dynamic, interactive, and contextually responsive approach, actively involving a large language model (LLM) from the domain of natural language processing (NLP) in artificial intelligence (AI) to produce multiple statements of potential ideas for different design problems. Integrating such AI models with ideation creates what we refer to as an Active Ideation scenario, which helps foster continuous dialogue-based interaction, context-sensitive conversation, and prolific idea generation. A pilot study was conducted with thirty novice designers to generate ideas for given problems using traditional methods and the new CAI-based interface. The key parameters of fluency, novelty, and variety were used to compare the outcomes qualitatively by a panel of experts. The findings demonstrated the effectiveness of the proposed tool for generating prolific, diverse and novel ideas. The interface was enhanced by incorporating a prompt-engineered structured dialogue style for each ideation stage to make it uniform and more convenient for the designers. The resulting responses of such a structured CAI interface were found to be more succinct and aligned towards the subsequent design stage, namely conceptualization. The paper thus established the rich potential of using Generative AI (Gen-AI) for the early ill-structured phase of the creative product design process.

Museums : A functional analysis
Creators: name: Stewart, John Robert
Publisher: name: University of British Columbia

description: Museums are important institutions of culture and education in every modern society. However, both museums themselves and external researchers have often considered as important only those records that pertain directly to the acquisition, meaning and provenance of the objects in museum collections. In recent years many types of historical and scientific scholars have discovered the value of many classes of museum records to their research. This, combined with an increased demand for public accountability, has brought attention to the potential value of all classes of museum records. This thesis considers the value of the full range of museum records through an understanding of museum functions, activities and organizational structure. Museums have evolved from collections, which have been a part of human culture for thousands of years. Collections have been embodied in the institutions called museums, and separated from their original practical, religious, or personal purposes, only in the modern era. Throughout their history museums have had the same common functions of collecting objects, preserving objects, educating the public, and sustaining themselves. Museum records are created by museum offices, or officers, as they carry out their mandated functions and activities. To appraise museum records it is necessary to understand the activities that comprise the basic museum functions, which classes of records are created by those activities, and which museum positions typically perform those activities and functions. This analysis enables us to see the functional genesis and nature of museum records, no matter what types of museum officers perform the activities, and no matter how the work is organized in any particular museum. The records can be evaluated, not in relation to some abstract idea of value, but in relation to their documentation of the functions and activities of an institution. Museum records need to be appraised in relation to their primary value to the creating institutions as well as their secondary value to external users. The full range of museum activities require documentation to enable museums to carryout their assigned functions, and for external users to satisfy a variety of cultural, historical, scientific, legal and personal research needs. Museum records have some unique characteristics. The records with the highest primary value are those that document the acquisition, provenance, use and meaning of museum collections. These records remain permanently active for ongoing museum activities and, at the same time, have the highest secondary value for external users. Museum records are also unusual in that these collections-related records, with the highest primary and secondary value, are created at the middle or lower organizational levels of curators, registrars, conservators, and their technical assistants.

description: Radiative shocks are strong shocks characterized by plasma at a high temperature emitting an important fraction of its energy as radiation. Radiative shocks are commonly found in many astrophysical systems and are templates of radiative hydrodynamic flows, which can be studied experimentally using high-power lasers. This is not only important in the context of laboratory astrophysics but also to benchmark numerical studies. We present details on the design of experiments on radiative shocks in xenon gas performed at the kJ scale PALS laser facility. It includes technical specifications for the tube targets design and numerical studies with the 1-D radiative hydrodynamics code MULTI. Emphasis is given to the technical feasibility of an XUV imaging diagnostic with a 21 nm (~58 eV) probing beam, which allows to probe simultaneously the post-shock and the precursor region ahead of the shock. The novel design of the target together with the improved X-ray optics and XUV source allow to show both the dense post-shock structure and the precursor of the radiative shock.

Through the blackness -- high p_T hadrons probing the central region of 200 AGeV Au-Au collisions

Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The energy loss of high p_T partons propagating through a hot and dense medium is regarded as a valuable tool to probe the medium created in ultrarelativistic heavy-ion collisions. The angular correlation pattern of hadrons associated with a hard trigger in the region of p_T ~1-2 GeV which exhibits a dip in the expected position of the away side jet has given rise to the idea that energy is lost predominantly to propagating collective modes ('Mach cones'). Recent measurements by the STAR collaboration have shown that for a high p_T > 8 GeV trigger the angular pattern of associate hadrons for p_T > 4 GeV shows the emergence of the expected away side peak. These di-jet events suggest that the away side parton may emerge occasionally without substantial energy loss. Since in such a back-to-back configuration one of the partons may travel through the central region of the fireball, the average in-medium pathlength is substantial and the expected energy loss is not only sensitive to the initial geometry of matter but also to the change of geometry due to expansion. We show that radiative energy loss is able to explain the dijet events provided that the expansion of the medium is taken into account.

description: Klein-Gordon equations describe the dynamics of waves/particles in sub-atomic scales. For nonlinear Klein-Gordon equations, their breather solutions are usually known as time periodic solutions with the vanishing spatial-boundary condition. The existence of breather solution is known for the Sine-Gordon equations, while the Sine-Gordon equations are also known as the soliton equation. The breather solutions is a certain kind of time periodic solutions that are not only play an essential role in the bridging path to the chaotic dynamics, but provide multi-dimensional closed loops inside phase space. In this paper, based on the high-precision numerical scheme, the appearance of breather mode is studied for nonlinear Klein-Gordon equations with periodic boundary condition. The spatial periodic boundary condition is imposed, so that the breathing-type solution in our scope is periodic with respect both to time and space. In conclusion, the existence condition of space-time periodic solution is presented, and the compact manifolds inside the infinite-dimensional dynamical system is shown. The space-time breather solutions of Klein-Gordon equations can be a fundamental building block for the sub-atomic nonlinear dynamics.

Next, we present the findings of a survey that was conducted in 100 companies and it was based on three layers of compliance (Greek legislation, Greek code of Corporate Governance and Best international practices of corporate governance). Furthermore, we compared our study with previous related surveys. The general conclusion was that Greek companies improve the quality of their governance and more they pay attention to that young aspect of business administration. It is indicative the fact that the score of overall quality has risen almost 14% since 2003, when the Greek law was recent.

description: We present a model of the evolution of control systems in a genome under environmental constraints. The model conceptually follows the Jacob and Monod model of gene control. Genes contain control elements which respond to the internal state of the cell as well as the environment to control expression of a coding region. Control and coding regions evolve to maximize a fitness function between expressed coding sequences and the environment. 118 runs of the model run to an average of 1.4 x 10^6 `generations' each with a range of starting parameters probed the conditions under which genomes evolved a `default style' of control. Unexpectedly, the control logic that evolved was not significantly correlated to the complexity of the environment. Genetic logic was strongly correlated with genome complexity and with the fraction of genes active in the cell at any one time. More complex genomes correlated with the evolution of genetic controls in which genes were active (`default on'), and a low fraction of genes being expressed correlated with a genetic logic in which genes were biased to being inactive unless positively activated (`default off' logic). We discuss how this might relate to the evolution of the complex eukaryotic genome, which operates in a `default off' mode.

description: This report presents the outcomes of a participatory process in which these multiple development paths and futures of prosumer business models, social dynamics, and technical systems were explored with a wide range of stakeholders. First, we outline the objective of the report and the process of the Participatory Integrated Assessment (PIA) (Section 1). Second, we discuss six leverage points, or ‘buttons to switch’ for affecting the future, which were distilled from the rich outcomes of this participatory process (Section 2). Third, we highlight three key value tensions which underlie these leverage points, and for which value prioritisations will need to be made. Once a decision has been made on what the desired direction for the future is, readers can refer to the respective roadmap associated with that future (Section 3). Fourth, 10 provocations for mainstreaming prosumerism towards 2050 are presented: a conversation tool which can be used to discuss what a preferred future for prosumerism looks like (Section 4). Fifth, and finally, we provide inspiration for how to put the provocations to use through appreciative inquiry (Section 5). This report serves multiple audiences and interests. Therefore, we have broken down the structure of the report into several sections. You can read these separately, depending on what you want to know about the future of mainstreaming prosumerism in Europe.

description: Η συγκεκριμένη διπλωματική εργασία αναφέρεται σε δύο από τις διασημότερες νουβέλες του 19ου αιώνα, τον Frankenstein της Mary Shelley και το Ο δρ. Τζέκυλλ και ο κος Χάυντ του R.L. Stevenson. Περιέχει μικρή περίληψη των κειμένων καθώς και βιογραφικά στοιχεία των δύο συγγραφέων που βοηθούν στην ευκολότερη κατανόηση για τον τρόπο και τις αιτίες που γράφτηκαν. Στην εργασία αναζητούνται οι κοινοί τόποι και προβληματισμοί των έργων ενώ γίνεται προσπάθεια να προσεγγιστούν και να αναλυθούν μέσω των ψυχαναλυτικών θεωριών ή το συνδυασμό ψυχαναλυτικών και φεμινιστικών θεωριών στην περίπτωση της νουβέλας της Shelley. Στο δεύτερο μέρος της εργασίας, περνάμε στο ευρύτερο πλαίσιο των πολιτισμικών σπουδών και βλέπουμε την «τύχη» των δύο κειμένων στον κινηματογράφο, καθώς η μαζική δύναμη της pop culture τα δυναμώνει και τα φέρνει μέχρι και τις μέρες μας, μετατρέποντας τους βασικούς χαρακτήρες σε pop icons και χαρακτηρίζοντας τις δύο νουβέλες κλασσικές και επιδραστικές για δύο σχεδόν αιώνες.
description: This thesis refers to two of the most famous novels of 19th century, Mary Shelley’s Frankenstein and R.L. Stevenson’s The strange case of Dr. Jekyll and Mr. Hyde. It includes a summary of the two works as well as biographic information of the two writers which assist the understanding of the way and the reasons they were written for. In this thesis the common place and the ideas are searched while there is an attempt to approach and analyze them through the psychoanalytic theories or the combination of psychoanalytic and feminist in the case of Shelley’s novel. In the second part of the project we move forward to the general frame of cultural studies and we see the appearance of these works in the cinema, as the massive power of the pop culture strengthens them and brings them forward nowadays, transforming the basic characters to pop icons and characterizing the two novels as classical and influential for almost two centuries.

description: We investigate the possibility of dividing quantum channels into concatenations of other channels, thereby studying the semigroup structure of the set of completely-positive trace-preserving maps. We show the existence of 'indivisible' channels which can not be written as non-trivial products of other channels and study the set of 'infinitesimal divisible' channels which are elements of continuous completely positive evolutions. For qubit channels we obtain a complete characterization of the sets of indivisible and infinitesimal divisible channels. Moreover, we identify those channels which are solutions of time-dependent master equations for both positive and completely positive evolutions. For arbitrary finite dimension we prove a representation theorem for elements of continuous completely positive evolutions based on new results on determinants of quantum channels and Markovian approximations.

description: Η παρούσα εργασία μελετά την απόδοση ενός συστήματος Grid το οποίο αποτελείται από δύο ετερογενείς συστοιχίες εξυπηρετών οι οποίες επικοινωνούν με τον Grid Scheduler. Για την αποτίμηση της απόδοσης μελετώνται αρχικά δύο πολιτικές δρομολόγησης εργασιών στα sites από τον Grid Scheduler, η πολιτική Βάσει Φόρτου και η Τυχαία πολιτική και στη συνέχεια μελετάται και μια Τρίτη πολιτική δρομολόγησης του GS,Εναλλάξ, που αποτελεί συνδυασμό των δύο προηγούμενων. Επιπλέον, μελετώνται και τρεις πολιτικές ανάθεσης εργασιών στους εξυπηρέτες από τους Local Schedulers, η πολιτική Shortest Queue, Random και Hybrid. Για να μπορέσουμε να έχουμε τη βέλτιστη εξισορρόπηση του φόρτου εργασιών μεταξύ των sites και των εξυπηρετών τους, μελετάται κάθε πιθανός συνδυασμός των πολιτικών δρομολόγησης του GS με τις πολιτικές ανάθεσης των LS. Στο πρώτο μέρος της εργασίας βλέπουμε κάποια γενικά χαρακτηριστικά των συστημάτων Πλέγματος, της προσομοίωσης και της θεωρίας Ουρών. Το δεύτερο μέρος περιγράφει αναλυτικά το μοντέλο μας και τις παραδοχές του καθώς και τα προγράμματα προσομοίωσης που εκτελέστηκαν. Εν τέλει, γίνεται σχολιαμός των αποτελεσμάτων και των συμπερασμάτων που προκύπτουν.
description: This work studies a Grid system’s performance, which consists of two heterogeneous server clusters that can communicate with a Grid Scheduler. In order to evaluate the system performance, two different job scheduling policies from the Grid Scheduler to sites are primarily examined, Load Based and Random policy, and then another third job scheduling policy from the GS is examined, which is a combination of the two other. What is more, three different local job allocation policies to processors are examined, the Shortest Queue, the Random and the Cyclical policies. In order to balance the workload among the sites and the processors in each site, every possible different combination of both the job scheduling policies and the local job allocation policies are applied. The first part of our paper, introduces the general characteristics of a grid system and simulation and queuing theory as well. In the second part, our model is precisely described and the simulation programmes are presented. Finally, the conclusions that came from the results are presented and criticized.

description: We investigate a two-dimensional (2D) heterostructure consisting of few-layer direct bandgap ReS2, a thin h-BN layer and a monolayer graphene for application to various electronic devices. Metal-insulator-semiconductor (MIS)-type devices with two-dimensional (2D) van-der-Waals (vdW) heterostructures have recently been studied as important components to realize various multifunctional device applications in analogue and digital electronics. The tunnel diodes of ReS2/h-BN/graphene exhibit light tuneable rectifying behaviours with low ideality factors and nearly temperature independent electrical characteristics. The devices behave like conventional MIS-type tunnel diodes for logic gate applications. Furthermore, similar vertical heterostructures are shown to operate in field effect transistors with a low threshold voltage and a memory device with a large memory gate for future multifunctional device applications.

description: The unparticle effects on $t\bar t$ production at the future photon collider are investigated. Distributions of $t\bar t$ invariant mass and that for transverse momentum of top quark with respect to Standard Model and unparticle production are predicted. An odd valley with scalar unparticle contribution appears for some values of $d_{\U}$, which is due to the big cancellation between the contribution from SM and that from unparticle. This character may be used to study the properties of scalar unparticle. Our investigations also show that scalar unparticle may play a significant role in $t \bar t$ production at photon collider if it exists.

description: Network reliability is an important metric to evaluate the connectivity among given vertices in uncertain graphs. Since the network reliability problem is known as #P-complete, existing studies have used approximation techniques. In this paper, we propose a new sampling-based approach that efficiently and accurately approximates network reliability. Our approach improves efficiency by reducing the number of samples based on stratified sampling. We theoretically guarantee that our approach improves the accuracy of approximation by using lower and upper bounds of network reliability, even though it reduces the number of samples. To efficiently compute the bounds, we develop an extended BDD, called S2BDD. During constructing the S2BDD, our approach employs dynamic programming for efficiently sampling possible graphs. Our experiment with real datasets demonstrates that our approach is up to 51.2 times faster than the existing sampling-based approach with higher accuracy.

description: Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer that can progress into invasive ductal carcinoma (IDC). Studies suggest DCIS is often overtreated since a considerable part of DCIS lesions may never progress into IDC. Lower grade lesions have a lower progression speed and risk, possibly allowing treatment de-escalation. However, studies show significant inter-observer variation in DCIS grading. Automated image analysis may provide an objective solution to address high subjectivity of DCIS grading by pathologists. In this study, we developed a deep learning-based DCIS grading system. It was developed using the consensus DCIS grade of three expert observers on a dataset of 1186 DCIS lesions from 59 patients. The inter-observer agreement, measured by quadratic weighted Cohen's kappa, was used to evaluate the system and compare its performance to that of expert observers. We present an analysis of the lesion-level and patient-level inter-observer agreement on an independent test set of 1001 lesions from 50 patients. The deep learning system (dl) achieved on average slightly higher inter-observer agreement to the observers (o1, o2 and o3) ($κ_{o1,dl}=0.81, κ_{o2,dl}=0.53, κ_{o3,dl}=0.40$) than the observers amongst each other ($κ_{o1,o2}=0.58, κ_{o1,o3}=0.50, κ_{o2,o3}=0.42$) at the lesion-level. At the patient-level, the deep learning system achieved similar agreement to the observers ($κ_{o1,dl}=0.77, κ_{o2,dl}=0.75, κ_{o3,dl}=0.70$) as the observers amongst each other ($κ_{o1,o2}=0.77, κ_{o1,o3}=0.75, κ_{o2,o3}=0.72$). In conclusion, we developed a deep learning-based DCIS grading system that achieved a performance similar to expert observers. We believe this is the first automated system that could assist pathologists by providing robust and reproducible second opinions on DCIS grade.
