description: We derive an analytic expression of the effective potential at finite temperature (T) and chemical potential (mu) in the strong-coupling lattice QCD for color SU(3) including next-to-next-to-leading order (NNLO) effects in the strong coupling expansion. NNLO effective action terms are systematically evaluated in the leading order of the large dimensional (1/d) expansion, and are found to come from some types of connected two plaquette configurations. We apply the extended Hubbard-Stratonovich transformation and a gluonic dressed fermion technique to the effective action, and obtain the effective potential as a function of T, mu, and two order parameters; chiral condensate and a vector potential field. The next-to-leading order (NLO) and NNLO effects result in modifications of the wave function renormalization factor, quark mass and chemical potential. We find that T_{c,mu=0} and mu_{c,T=0} are similar to the NLO results, whereas the position of the critical point is sensitive to NNLO corrections.

description: Catheter directed thrombolysis is a minimally invasive procedure that results in a significant reduction in venous obstruction after deep vein thrombosis. The technique implies the performance of phlebographies to monitor the thrombolysis progression. The objective of this paper is to describe the use of vascular ultrasound to follow the thrombus lysis and to adjust the catheter position according to the progression of the thrombolysis. This is the first case reported describing the application of ultrasound to monitor the thrombolysis. A 36-year woman was admitted ilio-femoral vein. The ipsilateral great saphenous vein was the percutaneous access to perform the anterograde thrombolysis. The procedure, including the control of thrombus lysis, as well as catheter progression was performed under ultrasound guidance. The thrombolysis took 52 hours. The patient has two years of follow-up without any complaint. The use of vascular ultrasound to monitor the thrombolysis has several theoretical advantages in patients with adequate biotopes. It minimizes the number of venograms and can be performed at the bedside. It is effective and inexpensive.

description: Pancoast tumours are defined as tumours arising from the upper lobe and invading the thoracic inlet,representing less than 5% of all lung cancers. Clinical features depend on the involved structures. For many years invasion of the spine was considered unresectable and fatal. Due to the progress in spine surgery, en bloc resection including the spine is nowadays possible. We report the first case of a successful en bloc vertebral resection of a Pancoast tumour in a 66 year-old male, with a squamous cell carcinoma, treated at our department in a multidisciplinary setting, after induction chemoradiotherapy. An en bloc resection including the left upper lobe, the first three ribs and the vertebral body of D2, was performed through a Paulson incision after posterior cervico-dorsal arthrodesis. A complete R0 resection was confirmed on the pathology specimen. Currently, one year after surgery, although no local recurrence has occurred, the patient is being treated with immunotherapy due to disease progression in the right acetabulum which was irradiated (20Gy) and then submitted to iliac resection and prothesis reconstruction.

description: Glauber dynamics of a bond-diluted Ising model on a Bethe lattice (a random graph with fixed connectivity) is investigated by an approximate theory which provides exact results for equilibrium properties. The time-dependent solutions of the dynamical system derived by this method are in good agreement with the results obtained by Monte Carlo simulations in almost all situations. Furthermore, the derived dynamical system exhibits a remarkable phenomenon that the magnetization shows multi-step relaxations at intermediate time scales in a low-temperature part of the Griffiths phase without bond percolation clusters.

Fenceline ecology of four grassland sites in the southern interior of British Columbia.
Creators: name: Ndawula-Senyimba, Michael Solomon
Publisher: name: University of British Columbia
Year: 2011

description: An ecological study of grassland communities separated by fence lines in the Southern Interior of British Columbia was conducted from spring 1968 to spring 1969. Measurements to compare plant species composition, herbage yield, growth habits and edaphic features on both sides of the fences were taken in the field. Soil organic matter was determined in the laboratory and moisture penetration patterns were demonstrated in the greenhouse. Heavy grazing resulted in the removal of the principal climax caespitose species and their replacement by shrubs, annuals and rhizomatous grasses. There were reductions in the composition, herbage yield and vigor of the caespitose species at all sites following heavy grazing. The success of the increasers under heavy grazing seemed to be favored by possession of rhizomes, presence of unpalatable flowering culms and inflorescences, shortness of tillers and an elaborate means of seed dispersal. The vegetational changes introduced by grazing on the heavily grazed side, resulted in a high level of organic matter in the top 25 cm. of soil, a high soil moisture content and high summer and low winter soil temperatures. The dense vegetation on the lightly grazed side modified both summer and winter soil temperatures. A technique was developed to determine the ability of caespitose grasses to redistribute moisture in the soil. It was demonstrated that aerial parts of Agropyron spicatum collect light rains and concentrate them in the rooting zone of the plant. This phenomenon is likely to be one of the adaptive features which enables caespitose species to dominate arid habitats. It is possible that the great susceptibility of Agropyron spicatum and other caespitose grasses to heavy grazing might be related to soil moisture disturbances introduced by the removal of aerial parts of the plants.

description: We give an overview on current status of the theoretical research on Thermoelectricity for correlated materials. We derive the theoretical formulas which become exact at low and high temperature and discuss the intermediate temperature results. In particular, we show that within Dynamical Mean Field Theory the low temperature sign of the thermopower is not necessary the same as in LDA, and that significant non-universality is expected due to strong correlations.

Analysis of Set-theoretic and Stochastic Models for Fusion under Unknown Correlations
Creators: name: Reinhardt, Marc
name: Noack, Benjamin

Publisher: name: Karlsruhe
Year: 2011

description: In data fusion theory, multiple estimates are combined to yield an optimal result. In this paper, the set of all possible results is investigated, when two random variables with unknown correlations are fused. As a first step, recursive processing of the set of estimates is examined. Besides set-theoretic considerations, the lack of knowledge about the unknown correlation coefficient is modeled as a stochastic quantity. Especially, a uniform model is analyzed, which provides a new optimization criterion for the covariance intersection algorithm in scalar state spaces. This approach is also generalized to multi-dimensional state spaces in an approximative, but fast and scalable way, so that consistent estimates are obtained.
Progressive Correction for Deterministic Dirac Mixture Approximations

Publisher: name: Karlsruhe
Year: 2011

description: Since the advent of Monte-Carlo particle filtering, particle representations of densities have become increasingly popular due to their flexibility and implicit adaptive resolution. In this paper, an algorithm for the multiplication of a systematic Dirac mixture (DM) approximation with a continuous likelihood function is presented, which applies a progressive correction scheme, in order to avoid the particle degeneration problem. The preservation of sample regularity and therefore, representation quality of the underlying smooth density, is ensured by including a new measure of smoothness for Dirac mixtures, the DM energy, into the distance measure. A comparison to common correction schemes in Monte-Carlo methods reveals large improvements especially in cases of small overlap between the likelihood and prior density, as well as for multi-modal likelihoods.

description: We determined the dominant polaron recombination loss mechanism in pristine and annealed polythiophene:fullerene blend solar cells by applying the photo-induced charge extraction by linearly increasing voltage (photo-CELIV) method in dependence on temperature. In pristine samples, we find a strongly temperature dependent bimolecular polaron recombination rate, which is reduced as compared to the Langevin theory. For the annealed sample, we observe a polaron decay rate which follows a third order of carrier concentration almost temperature independently.

description: We introduce a dual formulation of group field theories, making them a type of non-commutative field theories. In this formulation, the variables of the field are Lie algebra variables with a clear interpretation in terms of simplicial geometry. For Ooguri-type models, the Feynman amplitudes are simplicial path integrals for BF theories. This formulation suggests ways to impose the simplicity constraints involved in BF formulations of 4d gravity directly at the level of the group field theory action. We illustrate this by giving a new GFT definition of the Barrett-Crane model.

Phenolic metabolism in higher plants : I. Catechol biogenesis in Gaultheria, II. The biogenesis of rosmarinic acid in Mentha, III. Degradation of aromatic compounds by sterile plant tissues
Creators: name: Ellis, Brian Edward
Publisher: name: University of British Columbia
Year: 2011

description: I. Previous studies on biogenesis of simple phenols in plants have been restricted to hydroquinone. Among the other simple phenols, catechol is of particular interest because of its potential role as a ring-cleavage substrate. Tracer studies on the biogenesis of catechol in Gaultheria leaf discs showed that it was formed from salicylic acid by oxidative decarboxylation. Salicylate decarboxylating activity could be detected in buffered extracts of very young leaves. II. Among the numerous caffeic acid esters presently known in plants, only 3-0-caffeoylquinic acid (chlorogenic acid) has been studied in detail. Rosmarinic acid (alpha-O-caffeoyl-3, 4-dihydroxyphenyllactic acid) has been reported to occur in a number of plants but nothing was known of its biosynthesis or metabolic role. Tracer studies demonstrated that in Mentha the caffeic acid moiety was formed from phenylalanine via cinnamic and para-coumaric acids. In contrast, the structurally similar 3, 4-dihydroxyphenyllactic acid moiety was formed from tyrosine and 3, 4-dihydroxyphenylalanine. There was no evidence of the participation of a para-coumaroyl ester intermediate. Time-course studies and use of labelled rosmarinic acid showed that endogenous rosmarinic acid was turning over slowly. The caffeoyl moiety, however, does not appear to be contributing to the formation of insoluble polymers, as has been suggested for chlorogenic acid in other plants. III. Bacteria and fungi readily degrade aromatic compounds to carbon dioxide. Despite the large quantities of aromatic compounds formed in plants, little attention has been paid to the ability of plant tissues to degrade aromatic rings. No reported studies have used completely sterile plants and techniques. This has left open the possibility that the microflora associated with the plant might be carrying out the observed reactions. The ability of sterile plant tissue cultures to degrade aromatic ring-¹⁴C compounds to carbon dioxide was studied. It was established that a number of tissues (Ruta, Triticum, Phaseolus, Melilotus) have the ability to cleave the aromatic ring of phenylalanine. Melilotus tissue could also degrade cinnamic acid-ring-¹⁴C suggesting that a dihydroxy phenolic acid may be the ring-cleavage substrate. Neither Ruta nor Melilotus tissues were able to degrade benzoic acid or salicylic acid-ring-¹⁴C. Tryptophan benzene ring-¹⁴C was shown to be degraded to carbon dioxide by both Ruta and Melilotus. In summary, the ability of plants to cleave the benzene ring of aromatic compounds when free of micro-organisms was thus established.

Distribution and characterization of organo-clay complexes in selected Lower Fraser Valley soils
Creators: name: Parasher, Chander Dutt
Publisher: name: University of British Columbia
Year: 2011

description: In the study of the distribution of organo-clay complexes, thirty-four samples representing eight soil types were collected from the Lower Fraser Valley and the effectiveness of the three methods, viz. simple dispersion, insonation and chelating resin were examined. The use of a chelating resin was found most effective for quantitative studies while insonation was preferred for qualitative studies. For detailed characterization of the organo-clay complexes eight samples were chosen and ultrasonic agitation was used for isolating the organo-clay complexes. The organo-clay complexes varied widely in characteristics. The yield of complexes by simple dispersion, ultrasonic vibration and chelating resin ranged from 0.15 to 10.42, 0.20 to 17.20 and 1.25 to 25.70 percent by weight, respectively. The organo-clay complexes were analysed for their content of carbon, nitrogen, iron, silicon, aluminum along with carbohydrates, humic (HA) and fulvic (FA) acids. The C/N ratio of the selected complexes varied between 5.5 and 17.0 and carbohydrate content accounted for 3.3 to 16.0 percent of the complex carbon. The HA: FA ratio indicated that the major proportion of the organic component in this association was of fulvic nature, except in the case of the Podzolic Bf horizon samples in which about 2/3 of the extractable material was in the humic fraction. X-ray diffraction, infrared (IR) and differential thermal analysis were also conducted. The mineralogy was not observed to differ to a great extent except in the Ae horizon sample of the Orthic Podzol and the Btg of the Orthic Gleysol where montmorillonite was present in significant amounts. In most of the samples examined interlamellar inclusion of the organic matter was also observed. The differential thermal analysis exhibited a band near 320°C probably due to the elimination of some form of organic fraction. The IR studies indicated the bonding of silicon to organic components through oxygen linkages, however, there was no conclusive evidence of amide linkage formation between organic components and clay minerals.

description: This thesis explores the lives and death of children during the Bronze and Iron Ages, focussing on a study area in eastern England. It develops bespoke methods for analysing fingertip impressions and fingerprints found on prehistoric pottery assemblages, in order to explore the roles of children within communities of practice engaged in pottery making. It also investigates the status and treatment of the child’s body on death through analysis of human remains from across the study area. Bringing together data highlighting activities in which children were involved, with information on how their bodies were treated on death allows a discussion to be developed around the evidence for culturally recognised stages of childhood, and links between the experiences of the young living body with contemporary perceptions of the young dead body.

description: One of the key functions of PIDs is to make links to resources permanent and reliable. PIDs, and particularly DOIs, that do not resolve are therefore individually a nuisance and collectively a significant issue for the PID ecosystem as they undermine trust in its reliability.

 We will describe how the Qualitative Data Repository, QDR, has found examples of links to datasets on its site, both as URLs and as DOIs on multiple occasions, We will discuss two automated monitoring strategies that we have implemented in reaction to these discoveries: One based on Datacite’s automated reports, the other based on our own server logs.

 We will invite the audience to describe their own experience both with encountering broken PIDs and their efforts to fix and prevent them and catalog some most common causes and brainstorm fixes. Finally, while we are talking about broken PIDs, we will lead all participants in a chant of “Shame, JSTOR, Shame” for their continued publication of broken DOIs (see https://twitter.com/adam42smith/status/1299503139767414786 ).
On the Residual Effective Potential within Global One-Dimensional Quantum Gravity

description: The global one-dimensional quantum gravity is the model of quantum gravity which arises from the global one-dimensionality conjecture within quantum general relativity, first considered by the author in 2010 and then in 2012. In this model the global dimension is a determinant of a metric of three-dimensional space embedded into an enveloping Lorentizan four-dimensional spacetime. In 2012, it has already been presented by the author that this model can be extended to any Lorentzian D + 1-dimensional spacetime, where D is a dimension of space, and resulting in the global one-dimensional model of a higher dimensional quantum gravity. The purely quantum-mechanical part of this model is a minimal effective model within the quantum geometrodynamics, introduced by J.A. Wheeler and B.S. DeWitt in the 1960s, but the effective potential is manifestly different from the one considered by Wheeler & DeWitt. Moreover, in our model the wave functionals solving the quantum gravity are one-variable smooth functions and, therefore, the troublesome mathematical technique of the Feynman functional integration present in the Hawking formulation of quantum gravity, is absent is this model, what makes it a mathematically consistent theory of quantum gravitation. In this paper, we discuss in some detail a certain part of the global one-dimensional model already proposed in 2010, and then developed in 2012. The generalized functional expansion of the effective potential and the residual approximation, which describe the embedded spaces which are maximally symmetric three-dimensional Einstein's manifolds, whose lead to the Newton-Coulomb type potential in the quantum gravity model, are considered. Furthermore, scenarios related to few selected specific forms of the effective potential are suggested as physically interesting and discussed.

These contributions are related to dipolar relaxation and molecular organization in the monolayer in one hand, and the presence of defects at the silicon/molecule interface in the other hand. We propose a small signal equivalent circuit suitable for the simulations of these molecular devices in commercial device simulators. Our results concern monolayers of alkyl chains considered as a model system but can be extended to other molecular monolayers. These results open door to a better control and optimization of molecular devices.

Factors affecting the nitrate content of foods
Creators: name: Bodhiphala, Tewee
Publisher: name: University of British Columbia
Year: 2011

description: The nitrate content of some foods was determined. Canned food, baby food, frozen food, and fresh vegetables were analyzed. Among them spinach and beet were found to have the highest nitrate-nitrogen content and frozen food had higher nitrate-nitrogen content than other food products analyzed. Nitrate-nitrogen of food is partially transferred to the liquid portion whenever the food consists of any liquid. The amount of nitrate in the liquid portion seemed, to be higher than in the solid portion except in bean which has a protective surface layer as a factor of lowering the nitrate found in the liquid portion. The rate of nitrate transferring from solid portion to liquid portion was not the same for all foods and was not the same even from different parts of the same plant. Nitrate-nitrogen was not destroyed by cooking. Even after pouring off cooking water, some nitrate-nitrogen still remained in the solid portion. The distribution of nitrate among different plant parts was not uniform: bean leaves, beet root and spinach petioles were found to have higher nitrate than other parts. Nitrogen fertilization readily increased nitrate-nitrogen content in spinach. The sodium salicylate method was found to be the most reliable method for nitrate determination among different methods used in this study. The determination might be affected by many factors occuring during the procedure of analysis such as procedure of extraction and the spectrophotometer blanks used. Oxidising agents, arid reducing agents do not seem to affect the analysis but pH variation and sucrose which might occur in food probably are factors affecting apparent nitrate content. Cooking did quickly destroy spinach nitrate reductase enzyme activity. This means that nitrite will not be found after cooking unless the enzyme is regenerated, or unless there is microbial activity.

description: We investigate the symmetry breaking role of noise in adiabatic quantum computing using the example of the CNOT gate. In particular, we analyse situations where the choice of initial configuration leads to symmetries in the Hamiltonian and degeneracies in the spectrum. We show that, in these situations, there exists an optimal level of noise that maximises the success probability and the fidelity of the final state. The effects of an artificial noise source with a time-dependent amplitude are also explored and it is found that such a scheme would offer a considerable performance enhancement.

description: A 20-year old male patient presented at the emergency department with occipital headache, chest pain and hemoptysis, following an accident while playing sports (fall after impact with another player). There was no known relevant patient history or usual medication. Initial work-up revealed an occipital hematoma and right lumbar pain, in the absence of rib fracture or subcutaneous emphysema. Crackles at the lower-third of the right hemithorax were noted at auscultation. No abnormalities were found on the cranial computed tomography (CT) or chest x-ray. Due to a new onset of hemoptysis, a chest CT was carried out showing a pulmonary subpleural, para-vertebral, air-filled lesion, measuring 1.2 x 7cm (axial x longitudinal diameter). Given the recent traumatic injury, a pneumatocele was suspected secondary to a discrete parenchymal laceration. An adjacent 5cm ground-glass opacity was seen, suggesting an associated alveolar hemorrhage (figure 1). Owing to clinical stability, the patient was not submitted to an emergency bronchoscopy and was admitted for a two-day surveillance. There was a complete symptomatic relief on the discharge day and re-evaluation following one month showed a total filling of the pulmonary parenchymal lesion (figure 2).

Visual Stabilization of Beating Heart Motion by Model-based Transformation of Image Sequences
Creators: name: Bogatyrenko, Evgeniya

Publisher: name: Karlsruhe
Year: 2011

description: In order to assist a surgeon by operating on a beating heart, visual stabilization makes the beating heart appear still to a surgeon by providing the current heart view as stationary and non-moving. In this way, the surgeon is not disturbed during an operation by a motion of the heart and can get an impression of performing conventional surgery. In contrast to existing methods for visual stabilization, the proposed approach involves a model-based transformation of image sequences provided by a camera system. This transformation incorporates the knowledge of physical characteristics of the heart in form of a mathematical model of the heart surface. Its main advantage is that the uncertainties of the model and measurements are considered. This occurs by estimating the parameters of the transformation. Furthermore, the quality of the visual stabilization is additionally improved by adapting the parameters of the underlying physical model. A performance of the proposed approach is evaluated in an experiment with a pressure-regulated artificial heart. In comparison to standard approaches, it provides superior results illustrating the high quality of the visual stabilization.

We use 2XMMp X-ray data, SDSS-DR5, NOT and UKIRT optical/NIR photometric data and Subaru MOIRCS IR spectroscopy to study the properties of 2XMM J123204+215255. We created a model SED including an obscured QSO and the host galaxy component to constrain the optical/IR extinction and the relative contribution of the AGN and the galaxy to the total emission. 2XMM J123204+215255 is a bright X-ray source with f_X~10^{-12} erg cm^{-2} s^{-1} (2-10 keV energy band) which has no detection down to a magnitude i' > 25.2. NIR imaging reveals a faint K-band counterpart and NIR spectroscopy shows a single broad (FWHM=5300 km/s) emission line, which is almost certainly H-alpha at z=1.87. The X-ray spectrum shows evidence of significant absorption (N_H > 10^{23} cm^{-2}), typical of type 2 AGN, but the broad H-alpha emission suggests a type 1 AGN classification. The very red optical/NIR colours (i'-K > 5.3) strongly suggest significant reddening however. We find that simple modelling can successfully reproduce the NIR continuum and strongly constrain the intrinsic nuclear optical/IR extinction to A_V~4, which turns out to be much smaller than the expected from the X-ray absorption (assuming Galactic gas-to-dust ratio).

fourth sector

description: The COVID-19 pandemic is a great challenge to our global society, exposing our limitations as well as new ways to generate adequate responses to global crises. Communities and individuals have spontaneously organized to deal with this crisis. Thousands of skillful individuals have engaged in the development of mechanical ventilators and masks, SARS-CoV-2 test kits, mobile applications for contact tracking and for coordinating mutual help and care, to name just a few. [...] we advise that the Canadian Government recognize this movement. This would lead to a second step of creating a normative system to regulate this new sector and to legitimize it [...].

Mapping the Two-Component Atomic Fermi Gas to the Nuclear Shell-Model

description: The physics of a two-component cold fermi gas is now frequently addressed in laboratories. Usually this is done for large samples of tens to hundreds of thousands of particles. However, it is now possible to produce few-body systems (1-100 particles) in very tight traps where the shell structure of the external potential becomes important. A system of two-species fermionic cold atoms with an attractive zero-range interaction is analogous to a simple model of nucleus in which neutrons and protons interact only through a residual pairing interaction. In this article, we discuss how the problem of a two-component atomic fermi gas in a tight external trap can be mapped to the nuclear shell model so that readily available many-body techniques in nuclear physics, such as the Shell Model Monte Carlo (SMMC) method, can be directly applied to the study of these systems. We demonstrate an application of the SMMC method by estimating the pairing correlations in a small two-component Fermi system with moderate-to-strong short-range two-body interactions in a three-dimensional harmonic external trapping potential.

Semi-Analytic Gaussian Assumed Density Filter
Creators: name: Huber, Marco F.

Publisher: name: Karlsruhe
Year: 2011

description: For Gaussian Assumed Density Filtering based on moment matching, a framework for the efficient calculation of posterior moments is proposed that exploits the structure of the given nonlinear system. The key idea is a careful discretization of some dimensions of the state space only in order to decompose the system into a set of nonlinear subsystems that are conditionally integrable in closed form. This approach is more efficient than full discretization approaches. In addition, the new decomposition is far more general than known Rao-Blackwellization approaches relying on conditionally linear subsystems. As a result, the new framework is applicable to a much larger class of nonlinear systems.

description: Excerpts from the report: Garden peppers are native to tropical America. They are gradually becoming more popular in home and market gardens, for canning, and for preserving in brine or by drying. Although not a major vegetable, they merit more extensive use because of their attractiveness in flavor and color and their high vitamin content. This publication describes the more common varieties of peppers, their cultural methods, and control of their insects and diseases.

description: Excerpts from the report: Nearly three-fourths of the land and water in the United States is in private ownership. This bulletin describes some of the opportunities for income-producing recreation enterprises on this private land. It tells of the assistance available from the U.S. Department of Agriculture and other public agencies to develop the Nation's rural recreation resources. In any locality, the many separate public services and individual enterprises can be combined into a substantial economic force through the USDA's rural areas development program. So, if you have a tract of land in the country or if you are interested in acquiring one for recreation use, this bulletin will help you decide whether you want to use it to provide rural recreation for income.
Causation, Measurement Relevance and No-conspiracy in EPR

Subjects: subject: Quantum Physics (quant-ph)

description: In this paper I assess the adequacy of no-conspiracy conditions employed in the usual derivations of the Bell inequality in the context of EPR correlations. First, I look at the EPR correlations from a purely phenomenological point of view and claim that common cause explanations of these cannot be ruled out. I argue that an appropriate common cause explanation requires that no-conspiracy conditions are re-interpreted as mere common cause-measurement independence conditions. In the right circumstances then, violations of measurement independence need not entail any kind of conspiracy (nor backwards in time causation). To the contrary, if measurement operations in the EPR context are taken to be causally relevant in a specific way to the experiment outcomes, their explicit causal role provides the grounds for a common cause explanation of the corresponding correlations.

description: This study focuses on tailoring elastic behaviour in an inherently brittle epoxy-based fibre-reinforced composite material formed through a gradient interphase with a bio-based thermoplastic elastomer. The fast-curing epoxy Araldite LY3585/Aradur 3475 was tested with two bio-based Pebax block copolymer grades. First, the interphase was characterised via optical hot-stage microscopy and Raman spectroscopy. The analysis unveiled pronounced diffusion followed by a reaction-induced phase separation, which led to the formation of an interphase with a thickness exceeding 200 μm at the temperatures associated with the curing process. Second, composite laminates were fabricated through a combined process of fused filament fabrication and vacuum infusion, incorporating a flexible domain with variable stiffness properties. The material architecture exhibited brittle-to-ductile behaviour at the micrometre scale, with tailored flexible response under bending and stiff behaviour in tension. Consequently, the study anticipates using multi-scale toughened material structures for more efficient generative design concepts.

Incorporating Prior Knowledge into Nonparametric Conditional Density Estimation

name: Roschani, Masoud

Publisher: name: Karlsruhe
Year: 2011

description: In this paper, the problem of sparse nonparametric conditional density estimation based on samples and prior knowledge is addressed. The prior knowledge may be restricted to parts of the state space and given as generative models in form of mean-function constraints or as probabilistic models in the form of Gaussian mixtures. The key idea is the introduction of additional constraints and a modified kernel function into the conditional density estimation problem. This approach to using prior knowledge is a generic solution applicable to all nonparametric conditional density estimation approaches phrased as constrained optimization problems. The quality of the estimates, their sparseness, and the achievable improvements by using prior knowledge are shown in experiments for both Support-Vector Machine-based and integral distance-based conditional density estimation.
