Accurate and efficient network monitoring on mesh topologies via network coding
Creators: name: Gui, Jiaqi
Publisher: name: University of British Columbia

description: Accurate and efficient measurement of network-internal characteristics is critical for management and maintenance of large-scale networks. In this thesis, we propose a linear algebraic network tomography (LANT) framework for active inference of link loss rates on mesh topologies via network coding. Probe packets are transmitted from the sources to the destinations along a set of paths. Intermediate nodes linearly combine the received probes and transmit the coded probes using pre-determined coding coefficients. Although a smaller probe size can reduce the bandwidth usage of the network, the inference framework is not valid if the probe size falls below a certain threshold. To this end, we establish a tight lower bound on probe size which is necessary for establishing the mappings between the contents of the received probes and the losses on the different sets of paths. Then, we develop algorithms to find the coding coefficients such that the lower bound on probe size is achieved. Furthermore, we propose a linear algebraic approach to developing consistent estimators of link loss rates, which converge to the actual loss rates as the number of probes increases. We show that using the LANT framework, the identifiability of a link, which only depends on the network topology, is a necessary and sufficient condition for the consistent estimation of its loss rate. Simulation results show that the LANT framework achieves better estimation accuracy than the belief propagation (BP) algorithm for large number of probe packets.

description: This paper deals with an important subject in classification problems addressed by machine learning techniques: the evaluation of the influence of each of the features on the classification of individuals. Specifically, a measure of that influence is introduced using the Shapley value of cooperative games. In addition, an axiomatic characterisation of the proposed measure is provided based on properties of efficiency and balanced contributions. Furthermore, some experiments have been designed in order to validate the appropriate performance of such measure. Finally, the methodology introduced is applied to a sample of COVID-19 patients to study the influence of certain demographic or risk factors on various events of interest related to the evolution of the disease.
Contrasting Classical and Quantum Vacuum States in Non-Inertial Frames

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Classical electron theory with classical electromagnetic zero-point radiation (stochastic electrodynamics) is the classical theory which most closely approximates quantum electrodynamics. Indeed, in inertial frames, there is a general connection between classical field theories with classical zero-point radiation and quantum field theories. However, this connection does not extend to noninertial frames where the time parameter is not a geodesic coordinate. Quantum field theory applies the canonical quantization procedure (depending on the local time coordinate) to a mirror-walled box, and, in general, each non-inertial coordinate frame has its own vacuum state. In complete contrast, the spectrum of random classical zero-point radiation is based upon symmetry principles of relativistic spacetime; in empty space, the correlation functions depend upon only the geodesic separations (and their coordinate derivatives) between the spacetime points. It makes no difference whether a box of classical zero-point radiation is gradually or suddenly set into uniform acceleration; the radiation in the interior retains the same correlation function except for small end-point (Casimir) corrections. Thus in classical theory where zero-point radiation is defined in terms of geodesic separations, there is nothing physically comparable to the quantum distinction between the Minkowski and Rindler vacuum states. It is also noted that relativistic classical systems with internal potential energy must be spatially extended and can not be point systems. Based upon the classical analysis, it is suggested that the claimed heating effects of acceleration through the vacuum may not exist in nature.

description: Isomorphs are curves in the thermodynamic phase diagram along which structure and dynamics are invariant to a good approximation. There are two main ways to trace out isomorphs, the configurational-adiabat method and the direct-isomorph-check method. Recently a new method based on the scaling properties of forces was introduced and shown to work very well for atomic systems [T. B. Schroder, Phys. Rev. Lett. 129, 245501 (2022)]. A unique feature of this method is that it only requires a single equilibrium configuration for tracing out an isomorph. We here test generalizations of this method to molecular systems and compare to simulations of three simple molecular models: the asymmetric dumbbell model of two Lennard-Jones spheres, the symmetric inverse-power-law dumbbell model, and the Lewis-Wahnström o-terphenyl model. We introduce and test two force-based and one torque-based methods, all of which require just a single configuration for tracing out an isomorph. Overall, the method based on requiring invariant center-of-mass reduced forces works best.

description: Recent work in signal processing and statistics have focused on defining new regularization functions, which not only induce sparsity of the solution, but also take into account the structure of the problem. We present in this paper a class of convex penalties introduced in the machine learning community, which take the form of a sum of l_2 and l_infinity-norms over groups of variables. They extend the classical group-sparsity regularization in the sense that the groups possibly overlap, allowing more flexibility in the group design. We review efficient optimization methods to deal with the corresponding inverse problems, and their application to the problem of learning dictionaries of natural image patches: On the one hand, dictionary learning has indeed proven effective for various signal processing tasks. On the other hand, structured sparsity provides a natural framework for modeling dependencies between dictionary elements. We thus consider a structured sparse regularization to learn dictionaries embedded in a particular structure, for instance a tree or a two-dimensional grid. In the latter case, the results we obtain are similar to the dictionaries produced by topographic independent component analysis.

description: Robotic assembly planning enables architects to explicitly account for the assembly process during the design phase, and enables efficient building methods that profit from the robots' different capabilities. Previous work has addressed planning of robot assembly sequences and identifying the feasibility of architectural designs. This paper extends previous work by enabling planning with large, heterogeneous teams of robots. We present a planning system which enables parallelization of complex task and motion planning problems by iteratively solving smaller subproblems. Combining optimization methods to solve for manipulation constraints with a sampling-based bi-directional space-time path planner enables us to plan cooperative multi-robot manipulation with unknown arrival-times. Thus, our solver allows for completing subproblems and tasks with differing timescales and synchronizes them effectively. We demonstrate the approach on multiple case-studies to show the robustness over long planning horizons and scalability to many objects and agents of our algorithm. Finally, we also demonstrate the execution of the computed plans on two robot arms to showcase the feasibility in the real world.

description: Introduction:
 Issues related to the needs of female doctors in Obstetrics and Gynecology (O&G) have been discussed openly in Malaysia especially through the social media. Studies in UK and US showed that more than half of mothers had no gender preference when selecting their O&G doctors. In contrast, a study among religious population in Israel revealed that majority of the mothers' preferred female O&G doctors. This study was conducted to assess on mothers' preference of staff gender during childbirth. Methodology:
 This was a cross sectional study using a self-administered questionnaire. It involved post-natal mothers aged 18 and above, delivered via Spontaneous Vaginal Delivery (SVD) in 3 hospitals in East Coast of Malaysia. Results:
 A total of 171 post-natal mothers consented. The mean age was 29 (5.01) years old. 166 (97.1%) were Malays with Islam as the main religion (170, 99.4%). 147 mothers (86%) preferred female doctor for vaginal examination (VE) and 148 mothers (86.5%) preferred female doctor for delivery of the baby. Out of that, only 98 (66.7%) and 88 (59.5%) mothers were seen by female doctor for VE and childbirth respectively. Nevertheless, 125 (85.1%) mother were attended by either female doctor or nurse during VE and 138 (93.3%) during childbirth. Conclusion:
 As Islam is the predominant religion among the mothers, majority of them preferred to be attended by female doctor during VE and childbirth. Even though fewer mothers were seen by female doctor during delivery, the percentage was good when we considered the combination of female doctor and nurse.

description: A search for the Standard Model Higgs boson has been performed in the H->WW->lnujj channel using 4.7 fb^-1 of pp collision data recorded at a centre-of-mass energy of sqrt(s) = 7 TeV with the ATLAS detector at the Large Hadron Collider. Higgs boson candidates produced in association with zero, one or two jets are included in the analysis to maximize the acceptance for both gluon fusion and weak boson fusion Higgs boson production processes. No significant excess of events is observed over the expected background and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 300 GeV < mH < 600 GeV. The best sensitivity is reached for mH = 400 GeV, where the observed (expected) 95% confidence level upper bound on the cross section for H->WW produced in association with zero or one jet is 2.2 pb (1.9 pb), corresponding to 1.9 (1.6) times the Standard Model prediction. In the Higgs boson plus two jets channel, which is more sensitive to the weak boson fusion process, the observed (expected) 95% confidence level upper bound on the cross section for H->WW production with mH = 400 GeV is 0.7 pb (0.6 pb), corresponding to 7.9 (6.5) times the Standard Model prediction.

description: Recent years have seen the emergence of low-cost innovations targeted at economically weaker sections of the society, seeking to align business with social welfare. In many instances, results on the ground have been, however, rather sobering as firms have generally (probably justifiably) worried that “good quality, low price” products may cannibalize into their regular business. At the same time those very customers that were intended to benefit from the new approach have tended to shy away fearing low quality and social stigma of using cheap products. Using multiple case studies of successful affordability-driven innovations (“frugal innovations”) from India we investigate how firms can effectively reduce market and technology uncertainty of product innovations targeted at price-sensitive customers. The key criteria to success seem to lie in reducing the overall cost of ownership and enhancing customer perception of quality and image. The case studies reveal that affordability-driven innovations are especially successful when firms seek recourse to “open global innovation networks” (OGINs) for collaborative development in all phases of the innovation value chain

description: We propose seven criteria to single out physically reasonable non-singular black-hole models and adopt them to four different spherically symmetric models with a regular center and their rotating counterparts. In general relativity, all such non-singular black holes are non-generic with a certain matter field including a class of nonlinear electromagnetic fields. According to a criterion that the effective energy-momentum tensor should satisfy all the standard energy conditions in asymptotically flat regions, the well-known Bardeen and Hayward black holes are discarded. In contrast, the Dymnikova and Fan-Wang black holes respect the dominant energy condition everywhere. Although the rotating Fan-Wang black hole contains a curvature singularity, the rotating Dymnikova black hole is free from scalar polynomial curvature singularities and closed timelike curves. In addition, the dominant energy condition is respected on and outside the event horizons in the latter case. The absence of parallelly propagated curvature singularities remains an open question.

The influence of fitness level on the appearance of intrapulmonary arteriovenous shunting in healthy women
Creators: name: Kennedy, Jill Margaret
Publisher: name: University of British Columbia
Year: 2010

description: It was hypothesized that intrapulmonary arteriovenous shunts would be recruited at lower exercise intensities in highly trained individuals, compared to untrained and moderately trained individuals. Twenty-four women with normal lung and cardiac function, completed a maximal exercise test on a semi-supine cycle ergometer, while agitated saline contrast echocardiography was performed. Subjects were considered either untrained (VO₂peak < 40ml/kg/min), moderately trained (VO₂peak 40-45 ml/kg/min) or highly trained (VO₂peak > 45 ml/kg/min), as determined by their performance on the exercise test. One subject did not shunt, four subjects demonstrated shunt pre-exercise, and eleven subjects demonstrated shunt in stage one of exercise. Twenty subjects continued to shunt immediately post-exercise, and seventeen subjects continued to shunt three minutes post exercise. These findings contrast with other studies in the upright cycling position, indicating an effect of body position. Percent of VO₂peak at shunt onset was not different between the groups, indicating no influence of training status. Cardiac output was not different between groups, potentially due to the inability of subjects to reach their true maximum on the exercise test. Peripheral oxygen saturation did not drop significantly during exercise and there was no difference in the lowest value reached by each group, indicating no limitations to pulmonary gas exchange.

description: Human behavior often exhibit a scheme in which individuals adopt indifferent, neutral, or radical positions on a given topic. The mechanisms leading to community formation are strongly related with social pressure and the topology of the contact network. Here, we discuss an approach to model social behavior which accounts for the protection by alike peers proportional to their relative abundance in the closest neighborhood. We explore the ensuing non-linear dynamics emphasizing the role of the specific structure of the social network, modeled by scale-free graphs. We find that both coexistence of opinions and consensus on the default position are possible stationary states of the model. In particular, we show how these states critically depend on the heterogeneity of the social network and the specific distribution of external control elements.

title: Urban warfare and precautions in attack: framing the art of the practically possible
Creators: name: Griffiths, Jonathan
Publisher: name: University of Reading
Year: 2023

description: The continuing hostilities in Syria, Yemen, and Ukraine illustrate that cities invariably 
provide the stage for contemporary armed conflict. Within these complex urban 
environments, military operations take place amidst the densely packed physical terrain
and a concentrated civilian population. These features make urban warfare more 
dangerous for combatants and civilians alike. Given the rate of civilian casualties, some 
commentators are increasingly critical of what they consider to be the failure of modern 
armed forces to take the precautionary measures demanded by International Humanitarian 
Law (IHL) before undertaking urban attacks. However, in common with the wider body 
of IHL, the rules concerning the taking of precautions in attack reflect the careful 
balancing of military and humanitarian considerations by states, and such criticism tends 
to unduly skew that balance in favour of humanitarian concerns. In practice, IHL 
develops through state practice, and this makes it necessary to consider whether an IHL 
framework developed from the experiences of air warfare before 1977 remains fit for 
purpose in the context of contemporary urban warfare. 
This study explores the precise challenges posed by the urban environment to military 
practitioners and critically analyses the practice of states, through their armed forces, when 
conducting attacks as part of urban warfare. Although the existing IHL framework 
remains fit for purpose, the research highlights the importance of interpreting the relevant 
IHL rules as the Diplomatic Conference intended them to operate—as a means of 
reconciling military and humanitarian considerations. The taking of precautionary 
measures is not a zero-sum game: if precautions are ‘done well’, civilian harm mitigation 
need not impose undue constraints on the conduct of necessary military action.

description: The article describes a prose stanza as a group of sentences that are closely interconnected in meaning and syntactically, expressing a more complete development of thought compared to a separate sentence; one of the basic units of speech. In the linguistic literature, other terms are also used to refer to this unit, more often than others - "complex syntactic whole", as well as "super-phrasal unity", "paragraph", "component". However, the term "complex syntactic whole" emphasizes the syntactic nature of this unit, leaving aside its semantic unity. In addition, the term "complex whole" is used by some scholars to designate a complex sentence.

description: Graph Neural Networks (GNNs) have opened up a potential line of research for collaborative filtering (CF). The key power of GNNs is based on injecting collaborative signal into user and item embeddings which will contain information about user-item interactions after that. However, there are still some unsatisfactory points for a CF model that GNNs could have done better. The way in which the collaborative signal are extracted through an implicit feedback matrix that is essentially built on top of the message-passing architecture of GNNs, and it only helps to update the embedding based on the value of the items (or users) embeddings neighboring. By identifying the similarity weight of users through their interaction history, a key concept of CF, we endeavor to build a user-user weighted connection graph based on their similarity weight.
 In this study, we propose a recommendation framework, CombiGCN, in which item embeddings are only linearly propagated on the user-item interaction graph, while user embeddings are propagated simultaneously on both the user-user weighted connection graph and user-item interaction graph graphs with Light Graph Convolution (LGC) and combined in a simpler method by using the weighted sum of the embeddings for each layer. We also conducted experiments comparing CombiGCN with several state-of-the-art models on three real-world datasets.

description: The current document, titled 'TIME4CS statement to encourage Institutional Changes to promote Citizen Science', has been developed within the framework of the TIME4CS project which is funded by the European Union's Horizon 2020 Research and Innovation Programme under Grant Agreement No 101006201.  
The purpose of this Deliverable is to introduce the TIME4CS statement to invite the research performing/funding organisations (RPO/RFO) to embrace citizen science (CS) at the institutional level. The statement is accompanied by a set of practical, adaptable and innovative recommendations for research organisations beyond the TIME4CS consortium that are willing to pursue Institutional Change on CS and would like to follow a validated approach. This statement is based on the outputs of mapping and analysis of institutional CS adoption, building the TIME4CS knowledge base framework, as well as on the experience of developing and implementing the tailor-made Institutional Roadmaps by the consortium Implementing institutions.
To this end, the document comprises four main parts: 

Introduction explaining the process of the statement and the recommendations' co-creation as well as a relation of this document to other TIME4CS work packages.
TIME4CS statement with a subtitle "It is time for Citizen Science!" to encourage research institutions to adopt CS.
Recommendations for CS practitioners enriched by examples from the TIME4CS partner institutions' experiences presented around three main areas being at the heart of project discussions:

Boosting motivation of researchers and members of the public to initiate and participate in CS projects;
Ensuring funding for CS activities;
Defining tailored Institutional Roadmaps with concrete steps to follow.
 Initiatives to promote TIME4CS statement and the recommendations 
The document outlines successfully implemented actions and mechanisms leading to Institutional Change in the short, middle and long term. It expands the TIME4CS know-how to a larger audience and invites the research institutions to get inspired and learn from the TIME4CS experience on how to engage with CS at the institutional level and be in a better position when developing and promoting CS projects and applying for relevant funding opportunities.

description: India has emerged as a vibrant and versatile source for cost effective, "disruptive innovations" of various varieties. Price-sensitive consumers in a large and growing market keep inducing firms to apply "frugal engineering" for creating affordable products and services without compromising excessively on quality. Because, as The Economist asserts: "Frugal does not mean second-rate". Such innovations are characterized by high affordability, robustness, and "good enough" quality in a volume-driven market. Resource constraints motivate firms and entrepreneurs to think out-of-the-box. The trick lies in creating solutions that are able to circumvent given environmental constraints in a cost effective way. India's large and enormously young population faced with limited budgets, but well-endowed with high aspirations, provides an ideal experiment ground for many firms. Solutions created for the Indian market are often suitable for other developing countries in Asia, Africa and Latin America that frequently face similar socio-economic conditions. In some instances they succeed even in developed country markets by enabling significant cost reductions. This emergence as a hub for "frugal innovations" possibly suggests a "lead market" role for India. On the other hand, lead markets, as understood today, are characterized by high per capita income, great customer sophistication and high quality infrastructure. Such assumptions imply that lead markets, almost by default, can only exist in economically developed countries because only they can finance the development effort. Using two anchor-cases of product innovations aimed at price-sensitive segments in India we generate preliminary evidence to challenge some of the core assumptions of the "lead market" theory and propose that lead markets can emerge in developing countries too because market attractiveness (e.g. volume of demand, export possibilities) and technological capabilities are able to offset many other deficiencies. The supposed absence of customer sophistication is channelized into a challenge for supplier-side sophistication to design cost effective, "good enough" solutions ("low-cost, thin-margin") that can meet the aspirations of consumers in a highly competitive market. In order to master this challenge companies need access to a competent and sufficiently large technical base with first-hand knowledge of the ground situation of targeted customer groups ("social capital").

description: Leaves are a functionally important and visually conspicuous aspect of plant form. In nature, they present with a great diversity of shapes ranging, for example, from simple poplar leaves to prominently lobed maples through to highly compound tomato leaves. In this thesis, I examine the basis of this diversity using computer simulations. To elucidate the biological determinants of leaf form I first present three case studies focused on different aspects of leaf development. The first simulates leaf and midvein initiation in Brachypodium distachyon, and reproduces detailed biological observations of these processes. The remaining focus on leaf margin development, which is thought to play a primary morphogenetic role in the acquisition of leaf form. Thus for the second and third case studies, I propose a model of leaf margin development for simple leaves in Arabidopsis thaliana and compound leaves in Cardamine hirsuta. To simulate leaf margin development the boundary propagation method is proposed, which simulates the leaf margin and its propagation during development. The models developed using this method are qualitatively consistent with biological observations, and elucidate the role of the margin during simple and compound leaf development. To investigate natural leaf form diversity I propose a geometric model of leaf development based on the three molecularly detailed case-studies. This framework simulates leaf development as an interplay between patterning of the leaf margin, the establishment and growth of veins and the progression of maturation in the leaf blade. Although couched in geometric terms, the method is derived from the molecular level models developed in the three case studies, and is thus biologically motivated. This facilitates a biologically meaningful exploration of the diversity of leaf forms seen in nature using the framework. Additionally, it provides a procedural technique for generating leaf forms for computer graphics purposes.

description: We consider sequences of elliptic and parabolic operators in divergence form and depending on a family of vector fields. We show compactness results with respect to G-convergence, or H-convergence, by means of the compensated compactness theory, in a setting in which the existence of affine functions is not always guaranteed, due to the nature of the family of vector fields.

The same, but different: Stochasticity in binary destruction

description: Observations of binaries in clusters tend to be of visual binaries with separations of 10s - 100s au. Such binaries are 'intermediates' and their destruction or survival depends on the exact details of their individual dynamical history. We investigate the stochasticity of the destruction of such binaries and the differences between the initial and processed populations using N-body simulations. We concentrate on Orion Nebula Cluster-like clusters, where the observed binary separation distribution ranges from 62 - 620 au. We find that, starting from the same initial binary population in statistically identical clusters, the number of intermediate binaries that are destroyed after 1 Myr can vary by a factor of >2, and that the resulting separation distributions can be statistically completely different in initially substructured clusters. We also find that the mass ratio distributions are altered (destroying more low mass ratio systems), but not as significantly as the binary fractions or separation distributions. We conclude that finding very different intermediate (visual) binary populations in different clusters does not provide conclusive evidence that the initial populations were different.

description: We propose a quantum algorithm for inferring the molecular nuclear spin Hamiltonian from time-resolved measurements of spin-spin correlators, which can be obtained via nuclear magnetic resonance (NMR). We focus on learning the anisotropic dipolar term of the Hamiltonian, which generates dynamics that are challenging-to-classically-simulate in some contexts. We demonstrate the ability to directly estimate the Jacobian and Hessian of the corresponding learning problem on a quantum computer, allowing us to learn the Hamiltonian parameters. We develop algorithms for performing this computation on both noisy near-term and future fault-tolerant quantum computers. We argue that the former is promising as an early beyond-classical quantum application since it only requires evolution of a local spin Hamiltonian. We investigate the example of a protein (ubiquitin) confined in a membrane as a benchmark of our method. We isolate small spin clusters, demonstrate the convergence of our learning algorithm on one such example, and then investigate the learnability of these clusters as we cross the ergodic to non-ergodic phase transition by suppressing the dipolar interaction. We see a clear correspondence between a drop in the multifractal dimension measured across many-body eigenstates of these clusters, and a transition in the structure of the Hessian of the learning cost-function (from degenerate to learnable). Our hope is that such quantum computations might enable the interpretation and development of new NMR techniques for analyzing molecular structure.

Genetic interactions between Shox2 and Hox genes during the regional growth and development of the mouse limb

description: Homeobox genes of the Hox and Shox families have prominent roles in development and disease, with their independent mutation leading to regional shortening of the skeletal elements of the limb. In this work, we investigate whether Shox2 and Hox genes together coordinate limb development. By adapting double mRNA FISH to single embryos, we show that Shox2 and Hox genes have associated spatial expression dynamics, with Shox2 expression restricted to the proximal limb along with Hoxd9 and Hoxa11, juxtaposing the distal expression of Hoxa13 and Hoxd13. Their concerted proximal limb expression is critical for limb growth as Shox2 underexpression enhances, and Shox2 overexpression suppresses, Hox-mutant phenotypes. These genetic interactions are likely a result of Shox2 and Hox genes together promoting chondrocyte maturation, as their individual mutation similarly leads to reduced Runx2 expression in the humerus. In addition to cooperative functions in the proximal limb, Hox genes also repress Shox2 expression in a subset of cells of the distal limb. This repression may be important for normal development, since ectopic Shox2 expression disrupts Hox-dependent autopod morphogenesis. Finally, to provide insight into the molecular role of SHOX2 during development, proteins that co-purify with SHOX2 in the limb bud were identified using immunoprecipitation followed by mass spectrometry. This approach identifies numerous potential SHOX2 interacting partners, including the chromatin regulators SMARCE1 and HDAC2.

description: In this paper, we study a special exhaustion function on almost Hermitian manifolds and establish the existence result by using the Hessian comparison theorem. From the viewpoint of the exhaustion function, we establish related Schwarz type lemmas for almost holomorphic maps between two almost Hermitian manifolds. As corollaries, we deduce Liouville type theorems for almost holomorphic maps.

description: The South Pole Telescope (SPT) is a 10 meter telescope operating at mm wavelengths. It has recently completed a three-band survey covering 2500 sq. degrees. One of the survey's main goals is to detect galaxy clusters using Sunyaev-Zeldovich effect and use these clusters for a variety of cosmological and astrophysical studies such as the dark energy equation of state, the primordial non-gaussianity and the evolution of galaxy populations. Since 2005, we have been engaged in a comprehensive optical and near-infrared followup program (at wavelengths between 0.4 and 5 μm) to image high-significance SPT clusters, to measure their photometric redshifts, and to estimate the contamination rate of the candidate lists. These clusters are then used for various cosmological and astrophysical studies.
