Basic decision-making theory : a case study on the Oyu Tolgoi mine project in Mongolia
Creators: name: Bayasgalan, Naranzul
Publisher: name: University of British Columbia
Year: 2010

description: My thesis briefly discusses decision-making basic theory, in particular the deliberation method, and applies it to decision-making in the mining sector when making investment agreements between government and the private sector. However, decisions could be examined and applied in every industry sector. For instance, the mining sector includes many different decision making methods such as cost benefit analysis and socio-economic, environmental and health impact assessments. Every analysis and impact assessment requires different stakeholder participants and analysts from different sciences. This can sometimes make decisions more complicated. My thesis analyzes the planned Oyu Tolgoi (OT) copper and gold project in Mongolia using the Multi Account Evaluation method, which includes financial, economical, social and environmental analysis. It also briefly discusses social and environmental impacts from the Mongolian government point of view and whether this project will have a positive or negative influence on Mongolian economic and social development. My thesis also shows the current Mongolian decision-making situation and its problems.
Construction of a 3D-Structural Model of the Ohm-Graben zone in West-Thuringia, Germany

description: The Ohm-Graben zone in West-Thuringia, Germany, is located 20 km south of the Harz Mountains and 30 km east of the Leine Graben region. It stretches over 30 km from N to S and comprises multiple smaller graben structures, all striking NNE-SSW with a width of about 1 km. During the 20th century, its ground has been excessively explored for potassium salt mining. For that reason, it presents a good target for structural analysis of the Mesozoic sediments and – if possible – the Palaeozoic basement units. 30 km to the west at Göttingen, these basement rocks are the target of a geothermal exploration by the Universität Göttingen and the MEET project (Multidisciplinary and multi-context demonstration of EGS exploration and Exploitation Techniques and potentials), which provides the motivation for this project. Therefore, a structural 3D model has been created, using the software ‘MOVE’ by Midland Valley. The source data is made up of old geological maps, especially by Karl von Seebach (1872) and Curt Dietz (1923), survey reports, especially by Helmut Knape (1957) and Hans Kästner (1997), and borehole data from the potassium exploration. The result shows a most likely continuous graben system dominated by extension and strike-slip movement. The ages of the structures are not known precisely, but episodic movement at least from the lower Cretaceous to the Pleistocene is certain. The faults form negative flower structures, which converge in the level of the Zechstein salinar horizons in around 500 to 700 m depth below surface. The indications for strike-slip movement imply nearly vertical continuations of the faults into the Palaeozoic basement, but no drilling could verify this theory up to now. Salinar tectonics seems to compensate the extension movement only, but does not represent a major influencing factor like in the similar striking Leine valley graben to the west.

description: Developing a deep learning method for medical segmentation tasks heavily relies on a large amount of labeled data. However, the annotations require professional knowledge and are limited in number. Recently, semi-supervised learning has demonstrated great potential in medical segmentation tasks. Most existing methods related to cardiac magnetic resonance images only focus on regular images with similar domains and high image quality. A semi-supervised domain generalization method was developed in [2], which enhances the quality of pseudo labels on varied datasets. In this paper, we follow the strategy in [2] and present a domain generalization method for semi-supervised medical segmentation. Our main goal is to improve the quality of pseudo labels under extreme MRI Analysis with various domains. We perform Fourier transformation on input images to learn low-level statistics and cross-domain information. Then we feed the augmented images as input to the double cross pseudo supervision networks to calculate the variance among pseudo labels. We evaluate our method on the CMRxMotion dataset [1]. With only partially labeled data and without domain labels, our approach consistently generates accurate segmentation results of cardiac magnetic resonance images with different respiratory motions.

description: At impact of a liquid drop on a solid surface an air bubble can be entrapped. Here we show that two competing effects minimize the (relative) size of this entrained air bubble: For large drop impact velocity and large droplets the inertia of the liquid flattens the entrained bubble, whereas for small impact velocity and small droplets capillary forces minimize the entrained bubble. However, we demonstrate experimentally, theoretically, and numerically that in between there is an optimum, leading to maximal air bubble entrapment. Our results have a strong bearing on various applications in printing technology, microelectronics, immersion lithography, diagnostics, or agriculture.

description: A new code, named MAP, is written in Fortran language for magnetohydrodynamics (MHD) calculation with the adaptive mesh refinement (AMR) and Message Passing Interface (MPI) parallelization. There are several optional numerical schemes for computing the MHD part, namely, modified Mac Cormack Scheme (MMC), Lax-Friedrichs scheme (LF) and weighted essentially non-oscillatory (WENO) scheme. All of them are second order, two-step, component-wise schemes for hyperbolic conservative equations. The total variation diminishing (TVD) limiters and approximate Riemann solvers are also equipped. A high resolution can be achieved by the hierarchical block-structured AMR mesh. We use the extended generalized Lagrange multiplier (EGLM) MHD equations to reduce the non-divergence free error produced by the scheme in the magnetic induction equation. The numerical algorithms for the non-ideal terms, e.g., the resistivity and the thermal conduction, are also equipped in the MAP code. The details of the AMR and MPI algorithms are described in the paper.

Magneto-mechanical actuation model for fin-based locomotion

Subjects: subject: Robotics (cs.RO)

description: In this paper, we report the results from the analysis of a numerical model used for the design of a magnetic linear actuator with applications to fin-based locomotion. Most of the current robotic fish generate bending motion using rotary motors which implies at least one mechanical conversion of the motion. We seek a solution that directly bends the fin and, at the same time, is able to exploit the magneto-mechanical properties of the fin material. This strong fin-actuator coupling blends the actuator and the body of the robot, allowing cross optimization of the system's elements. We study a simplified model of an elastic element, a spring-mass system representing a flexible fin, subjected to nonlinear forcing, emulating magnetic interaction. The dynamics of the system is studied under unforced and periodic forcing conditions. The analysis is focused on the limit cycles present in the system, which allows the periodic bending of the fin and the generation of thrust. The frequency, maximum amplitude and center of the periodic orbits (offset of the bending) depend directly on the stiffness of the fin and the intensity of the forcing; we use this dependency to sketch a simple parameter controller. Although the model is strongly simplified, it provides means to estimate first values of the parameters for this kind of actuator and it is useful to evaluate the feasibility of minimal actuation control of such systems.

Low Temperature Oxidation of Heavy Crude Oil: Experimental Study and Reaction Modeling

description: In situ combustion (ISC) or air injection is one of the oldest thermal methods for enhanced oil recovery. In this technique, air or oxygen-enriched air is injected into the formation. A portion of the oil combusts in situ and provides heat, water, and product gases. Within the oil formation, three major combustion regions can be recognized: Low Temperature Oxidation (LTO), Thermal Cracking (TC), and High Temperature Oxidation (HTO). LTO provides fuel for HTO to sustain the combustion front. Therefore the success of ISC process directly depends on quality and quantity of LTO residues. The research documented in this thesis comprises four studies. The first study consisted of experimental investigations to evaluate the thermal behavior and reaction kinetics of an Alaskan and Lloydminster heavy oils by using thermogravimetric methods to examine isothermal and ramped temperature oxidation reactions. The results revealed that there are different subzones within the LTO zone with different reaction behaviors. In the second study, an LTO reaction conceptual scheme was developed based on the elemental studies. In the third study, a multiple subzone LTO reaction model was created, suitable for use in thermal reactive reservoir simulators. Based on the fourth study, LTO region was divided into two temperature subintervals with contrary reactive behaviors based on the moisture contents of the heavy oil samples. The results of the research provide overall insight about the LTO region, its subranges, major products within each subranges, and how to model it. This equips the ISC process the flexibility of controlling the temperature or water content to produce value-added LTO residues to sustain the combustion front. For instance if more heat is needed to keep the combustion front propagating, the temperature can be controlled in subzone that produce LTO residues with higher heating values or if air requirement is a concern temperature or water content can be controlled to produce residues with higher C/H ratios.

description: Several rapid parameter estimation methods have recently been advanced to deal with the computational challenges of the problem of Bayesian inference of the properties of compact binary sources detected in the upcoming science runs of the terrestrial network of gravitational wave detectors. Some of these methods are well-optimized to reconstruct gravitational wave signals in nearly real-time necessary for multi-messenger astronomy. In this context, this work presents a new, computationally efficient algorithm for fast evaluation of the likelihood function using a combination of numerical linear algebra and mesh-free interpolation methods. The proposed method can rapidly evaluate the likelihood function at any arbitrary point of the sample space at a negligible loss of accuracy and is an alternative to the grid-based parameter estimation schemes. We obtain posterior samples over model parameters for a canonical binary neutron star system by interfacing our fast likelihood evaluation method with the nested sampling algorithm. The marginalized posterior distributions obtained from these samples are statistically identical to those obtained by brute force calculations. We find that such Bayesian posteriors can be determined within a few minutes of detecting such transient compact binary sources, thereby improving the chances of their prompt follow-up observations with telescopes at different wavelengths. It may be possible to apply the blueprint of the meshfree technique presented in this study to Bayesian inference problems in other domains.

description: Quantum phase transitions typically result in a broadened critical or crossover region at nonzero temperature. Josephson arrays are a model of this phenomenon, exhibiting a superconductor-insulator transition at a critical wave impedance, and a well-understood insulating phase. Yet high-impedance arrays used in quantum computing and metrology apparently evade this transition, displaying superconducting behavior deep into the nominally insulating regime. The absence of critical behavior in such devices is not well understood. Here we show that, unlike the typical quantum-critical broadening scenario, in Josephson arrays temperature dramatically shifts the critical region. This shift leads to a regime of superconductivity at high temperature, arising from the melted zero-temperature insulator. Our results quantitatively explain the low-temperature onset of superconductivity in nominally insulating regimes, and the transition to the strongly insulating phase. We further present, to our knowledge, the first understanding of the onset of anomalous-metallic resistance saturation. This work demonstrates a non-trivial interplay between thermal effects and quantum criticality. A practical consequence is that, counterintuitively, the coherence of high-impedance quantum circuits is expected to be stabilized by thermal fluctuations.

description: Multipartite entanglement is an indispensable resource in quantum communication and computation, however, it is a challenging task to faithfully quantify this global property of multipartite quantum systems. In this work, we study the concurrence fill, which admits a geometric interpretation to measure genuine tripartite entanglement for the three-qubit system in [S. Xie {\it et al.}, Phys. Rev. Lett. \textbf{127}. 040403 (2021)]. First, we use the well-known three-tangle and bipartite concurrence to reformulate this quantifier for all pure states. We then construct an explicit example to conclusively show the concurrence fill can be increased under local operation and classical communications (LOCCs) {\it on average}, implying it is not an entanglement monotone. Moreover, we give a simple proof of the LOCC-monotonicity of three-tangle and find that the bipartite concurrence and the squared can have distinct performances under the same LOCCs. Finally, we propose a reliable monotone to quantify genuine tripartite entanglement, which can also be easily generalised to the multipartite system. Our results shed light on studying genuine entanglement and also reveal the complex structure of multipartite systems.

description: This research used an interpretivist exploratory case study design to examine how thirty nursing deans, directors or chairs (nursing deans) from 28 English language Canadian universities led institutional operations, set future direction and facilitated organizational decision-making. Leadership in universities has been described as a hybrid mix of traditional and entrepreneurial approaches (Collinson & Collinson, 2009). The administrator as conservator (Terry, 2003) and entrepreneurial public servant (Rowley, Lujan & Dolence, 1997) leadership models, which together form a leadership continuum, served as the foundation for describing, analyzing and interpreting this study’s findings. The nursing deans were found to use forty-nine leadership practices, thirty-seven (76%) of which reflected entrepreneurial public servant leadership. This signifies that these nursing deans used a blended leadership approach with entrepreneurial public servant practices being dominant. Personal values, globalization, university systems, structures and priorities, internal relationships, academic networks and mentors influenced the nursing deans’ entrepreneurial public servant leadership practices. The researcher also examined the amount of time that these nursing deans spent completing tasks in eight role function areas associated with the deanship position (Salewski, 2002). Approximately seventeen hours (30%) and eight hours (14%) of their 62 hour work week were spent completing tasks in the human resources/personnel and professional leadership/research role function areas respectively. This first national study of the Canadian university nursing deanship substantiated the shortage of nursing deans in Canada. At the time they were interviewed, 30 per cent of the nursing deans were holding acting or interim appointments. The turnover of nursing deans approximated 30 per cent between 2007 and 2009 and increased to 60 per cent by 2011. Senior university leaders can use the findings of this study as one foundation for reshaping the nursing deanship so that it becomes a more viable career option. The research also fulfills long-standing scholarly recommendations to study how university deans lead faculties (de Boer & Goedegebuure, 2009; Boyett, 1996) and offers a glimpse into the Canadian university deanship, which is understudied (Boyco & Jones, 2010).

description: Peniophora proxima Bres. is corticioid fungus belonging to family Peniophoraceae (Basidiomycota). It is easily distinguished by the numerous encrusted cystidia, gloeocystidia and ellipsoid spores. The species is considered a common white rot saprobe restricted only to the Buxus representatives. One of the most popular species of the Old world is Buxus sempervirens L. (European boxwood), native to western and southern Europe, northwest Africa, and southwest Asia. Although the species does not belong to the native flora of Bulgaria, for many years, the European boxwoods have been one of the most popular and widely used landscaping plants, in the form of ornamental shrubs or dense, evergreen hedges in shady places. P. proxima has been reported from different parts of Europe, but it has not been previously reported for Bulgaria. This article reports this new find from three localities in Bulgaria, while providing information about the morphological and ecological features of the species and commenting on the pattern of its distribution.

description: In this paper we analyze the third quantization of Horava-Lifshits theory of gravity without detail balance. We show that the Wheeler-DeWitt equation for Horava-Lifshits theory of gravity in minisuperspace approximation becomes the equation for time-dependent harmonic oscillator. After interpreting the scaling factor as the time, we are able to derive the third quantized wavefunction for multiverse. We also show in third quantized formalism it is possible that the universe can form from nothing. After we go on to analyze the effect of introducing interactions in the Wheeler-DeWitt equation. We see how this model of interacting universes can be used to explain baryogenesis with violation of baryon number conservation in the multiverse. We also analyze how this model can possibly explain the present value of the cosmological constant. Finally we analyze the possibility of the multiverse being formed from perturbations around a false vacuum and its decay to a true vacuum.

description: Background. Newborns and infants spend most of their time sleeping an immature sleep, which allows brain maturation a good neurodevelopment. Preterm birth is associated with abnormal brain development and alterations in later-in-life sleep patterns, carrying a high social burden, even when not accompanied by major neurological damages. Which impact prematurity itself can have on early sleep architecture, which influence it can have on well- known adverse outcomes, and which role brain lesions play in determining sleep patterns in preterm infants are still matter of debate. This exploratory pilot study aimed to describe the distribution of sleep states among very low birth weight (VLBW) infants, and to correlate it with neurobehavioral assessment at 35 weeks of post-menstrual age (PMA), and to observe if these persisted at term equivalent age (TEA) and at 6 months of corrected age (CA). Secondly, it aimed to assess if the presence of a major or minor brain lesion detected at MRI can affect sleep duration, distribution and quality. Methods. 10 VLBW were assessed at 34±2 weeks PMA with a 24-hours video- polysomnographic recording and received a neurobehavioral examination at the moment of the recording and at TEA (with Neonatal Behavior Assessment Scale; Hammersmith Neurological Neonatal Examination, and the neonatal visual battery). They were followed- up at 6 months CA with Griffiths’ Mental Development Scale III edition. Analysis of sleep stages distribution and spectra was conducted. Results. Total sleep time and total amount of transitional sleep (TS) significantly positively correlated with neurological, and neurobehavioral assessment at 34 weeks PMA, at TEA and with neurodevelopment at 6 months CA, while Sleep Onset Active Sleep (SOAS) had a negative association. Infants carrying severe-moderate brain lesions showed lower Total Sleep time (66.9% ± 7.39 vs 72.2% ± 3.52, p = 0.047) accompanied by a higher prevalence of SOAS (23.9% ± 10.2 vs 12.26% ± 5.5 p = 0.048), and showed a gradient for higher power of posterior slow activity (slow δ and δ) during SOAS from the posterior cerebral regions. Conclusions. Understanding sleep mechanism among preterm infants might provide future therapeutic/management strategies, which need to encompass sleep care. Further analyses with larger samples and more complex methods are claimed.

description: Background. Cognitive dysfunction and brain structural connectivity alterations have been observed in major depressive disorder (MDD). However, little is known about their interrelation. The present study follows a network approach to evaluate alterations in cognition-related brain structural networks. Methods. Cognitive performance of n = 805 healthy and n = 679 acutely depressed or remitted individuals was assessed using 14 cognitive tests aggregated into cognitive factors. The structural connectome was reconstructed from structural and diffusion-weighted magnetic resonance imaging. Associations between global connectivity strength and cognitive factors were established using linear regressions. Network-based statistics were applied to identify subnetworks of connections underlying these global-level associations. In exploratory analyses, effects of depression were assessed by evaluating remission status-related group differences in subnetwork-specific connectivity. Partial correlations were employed to directly test the complete triad of cognitive factors, depressive symptom severity, and subnetwork-specific connectivity strength. Results. All cognitive factors were associated with global connectivity strength. For each cognitive factor, network-based statistics identified a subnetwork of connections, revealing, for example, a subnetwork positively associated with processing speed. Within that subnetwork, acutely depressed patients showed significantly reduced connectivity strength compared to healthy controls. Moreover, connectivity strength in that subnetwork was associated to current depressive symptom severity independent of the previous disease course. Conclusions. Our study is the first to identify cognition-related structural brain networks in MDD patients, thereby revealing associations between cognitive deficits, depressive symptoms, and reduced structural connectivity. This supports the hypothesis that structural connectome alterations may mediate the association of cognitive deficits and depression severity.

description: ETS Related Gene (ERG) rearrangement is one of the most common genetic changes seen in roughly about 50% of prostate cancer (PCA) cases. The inhibitor of growth family member 3 (ING3) is a member of the ING tumor suppressor family. The deregulation of ING3 expression has been reported in various types of cancers. However, to date the role and function of ING3 in PCA as well as its relationship to ERG gene rearrangement has not been studied. Our initial observation from microarray expression profiling showed that ING3 was down-regulated in ERG positive prostate cancer samples in comparison to ERG negative tumors. In this work, we examined the expression and localization of ING3 in prostate cancer cell lines and tissue samples and its association to clinical outcome. We documented a significant association between ERG and ING3 and showed a significant association to the patients’ clinical outcome, thus highlighting a potential role for ING3 in prostate cancer progression.
Negative affective tendencies predict precursors of metabolic syndrome in physically healthy young women
Creators: name: Blackwell, Ekin
Publisher: name: University of British Columbia
Year: 2010

description: Accumulating evidence indicates that negative affect (NA) and positive affect (PA) are linked to a variety of physical health outcomes. However, there are a number of significant gaps in this literature. First of all, many commonly employed instruments assess broad psychological constructs rather than basic mood states. Second, these measures do not distinguish between valence and activation, two theoretically important dimensions of affect. This makes it difficult to sort out which key ingredients are involved in the affect and health connection. Third, with all the studies of medical patients, it is not evident whether moods matter causally or if they are confounded with disease severity. Finally, the biological mechanisms through which different moods might influence health are largely unknown. A critical question is whether NA and PA work through different pathways. The current research project was designed to help address these problems. The study employed a circumplex model of affect to track patterns of mood in physically healthy young women over the course of 6 months. Biological measures representing preclinical markers of metabolic disease were obtained at the end of this period. This methodology enabled us to examine the independent and joint contributions of different affective tendencies, varying on dimensions of valence and activation, to biological mechanisms involved in disease development. The findings revealed that the tendency to experience chronic negative emotions, regardless of their associated level of activation, predicted less optimal metabolic symptoms. In contrast, positive affective tendencies had neither a favorable nor detrimental effect on these outcomes. However, we found no evidence that NA and PA have unique biological correlates. The implications of these findings for models of emotion and health are discussed, and several potential avenues for future research are suggested.

Groundwater recharge in the West Nose Creek (WNC) watershed was largest in years when depression inundation resulted from both snowmelt runoff and large precipitation (>200 mm) in May-June, and smaller in years with only large May-June precipitation. However, the occurrence of snowmelt runoff without large May-June precipitation resulted in little to no groundwater recharge. The Versatile Soil Moisture Budget (VSMB) Upland-Depression model complex was tested against two numerically rigorous, widely distributed models for snow accumulation, snowmelt runoff, soil freeze-thawing processes, and groundwater recharge estimation in WNC watershed. Average RRMSE of SWE in VSMB was 0.47, snowmelt runoff matched observed data, and the soil thaw timing was consistently delayed. VMSB estimated groundwater recharge was comparable to observed data for three of the five years.

description: With recent advances in artificial intelligence, machine learning (ML) approaches have become an attractive tool in petroleum engineering, particularly for reservoir characterizations. A key reservoir property is hydrocarbon recovery factor (RF) whose accurate estimation would provide decisive insights to drilling and production strategies. Therefore, this study aims to estimate the hydrocarbon RF for exploration from various reservoir characteristics, such as porosity, permeability, pressure, and water saturation via the ML. We applied three regression-based models including the extreme gradient boosting (XGBoost), support vector machine (SVM), and stepwise multiple linear regression (MLR) and various combinations of three databases to construct ML models and estimate the oil and/or gas RF. Using two databases and the cross-validation method, we evaluated the performance of the ML models. In each iteration 90 and 10% of the data were respectively used to train and test the models. The third independent database was then used to further assess the constructed models. For both oil and gas RFs, we found that the XGBoost model estimated the RF for the train and test datasets more accurately than the SVM and MLR models. However, the performance of all the models were unsatisfactory for the independent databases. Results demonstrated that the ML algorithms were highly dependent and sensitive to the databases based on which they were trained. Statistical tests revealed that such unsatisfactory performances were because the distributions of input features and target variables in the train datasets were significantly different from those in the independent databases (p-value < 0.05).

description: Giovannetti, Lloyd, and Maccone [Phys. Rev. Lett. 100, 160501] proposed a quantum random access memory (QRAM) architecture to retrieve arbitrary superpositions of $N$ (quantum) memory cells via $O(\log(N))$ quantum switches and $O(\log(N))$ address qubits. Towards physical QRAM implementations, Chen et al. [PRX Quantum 2, 030319] recently showed that QRAM maps natively onto optically connected quantum networks with $O(\log(N))$ overhead and built-in error detection. However, modeling QRAM on large networks has been stymied by exponentially rising classical compute requirements. Here, we address this bottleneck by: (i) introducing a resource-efficient method for simulating large-scale noisy entanglement, allowing us to evaluate hundreds and even thousands of qubits under various noise channels; and (ii) analyzing Chen et al.'s network-based QRAM as an application at the scale of quantum data centers or near-term quantum internet; and (iii) introducing a modified network-based QRAM architecture to improve quantum fidelity and access rate. We conclude that network-based QRAM could be built with existing or near-term technologies leveraging photonic integrated circuits and atomic or atom-like quantum memories.

description: Four samples of open star clusters (OSCs) with average ages of 5.2, 18.6, 40, and 61 Myr have been analyzed. The selection of these OSCs was carried out from a narrow region inclined to the galactic axis y at an angle of 25$^\circ$. The spectral analysis of the vertical positions and velocities of the selected clusters showed that the Radcliffe wave is associated with OSCs no older than 30 Myr. The following estimates of the Radcliffe wave characteristics were obtained for the OSCs with an average age of 5.2 Myr: $z_{max}=117\pm12$ pc with the wavelength $λ=4.55\pm0.14$ kpc, the vertical velocity disturbance amplitude $W_{max}=4.86\pm0.19$ km s$^{-1}$ with the wavelength $λ=1.74\pm0.08$ kpc. For the OSCs with an average age of 18.6 Myr, the estimates are as follows: $z_{max} = 54\pm5$ pc and $λ=6.30\pm0.12$ kpc, the vertical velocity disturbance amplitude $W_{max}=7.90\pm0.16$ km s$^{-1}$ and $λ=0.83\pm0.11$ kpc. The radial motion of the Radcliffe wave away from the galactic center has been confirmed. The velocity of such movement is 10 pc Myr$^{-1}$. In our opinion, the spatial distribution of OSCs younger than 30 Myr does not contradict the hypothesis of the association of the Radcliffe wave with the impact of shock waves from supernova explosions that arose on an extended front comparable in scale to the entire wave, that is, about 2 kpc in size.

description: Protein function frequently involves conformational changes with large amplitude on timescales which are difficult and computationally expensive to access using molecular dynamics. In this paper, we report on the combination of three computationally inexpensive simulation methods-normal mode analysis using the elastic network model, rigidity analysis using the pebble game algorithm, and geometric simulation of protein motion-to explore conformational change along normal mode eigenvectors. Using a combination of ELNEMO and FIRST/FRODA software, large-amplitude motions in proteins with hundreds or thousands of residues can be rapidly explored within minutes using desktop computing resources. We apply the method to a representative set of six proteins covering a range of sizes and structural characteristics and show that the method identifies specific types of motion in each case and determines their amplitude limits.

description: Plants produce a vast array of specialized compounds known as secondary metabolites, which were originally thought to be non-essential for plant survival. However, we now know that secondary metabolites play integral roles in plant defense, signalling, reproduction and more. Proanthocyanidins (PAs) are a class of flavonoid polymers derived from the phenylpropanoid pathway. PAs accumulate in the seed coat, bark, and leaves of many plants and are believed to play a role in plant defense. Recent evidence of health benefits associated with PA consumption has spurred new research interests in PA biosynthesis. Many of the studies of seed coat PA biosynthesis have been conducted in non-crop species that produce a limited variety of PAs. Pea (Pisum sativum) offers a number of unique advantages for PA research. Peas produce large seed coats, which are easy to isolate. Dry peas are an important source of nutrition for both humans and livestock, enabling research integration into the human diet and commercial agriculture. Finally, centuries of breeding have produced a wide variety of pea cultivars, making pea a valuable phenotypic and genetic resource for plant research. Despite these advantages, PA biosynthesis in pea has not been well characterized. This work presents the seed coat PA chemical profile of three pea cultivars and the biochemical characterization of two PA branch point enzymes, anthocyanidin reductase and leucoanthocyanidin reductase, from pea. In addition, the seed coat transcriptomes of these three varieties were compared to those of two varieties lacking PAs in an effort to elucidate novel genetic mechanisms relating to PA biosynthesis. This comparative transcriptomic analysis was expanded to study general seed phenotypic differences between pea cultivars. Two target genes were identified; one related to seed weight and another to PAs, the latter of which was further characterized.
