description: Hymenaea martiana is a native tree known in Brazil as ‘jatobá’ and used in folk medicine to treat pain and inflammation. The aim of this work was to identify the flavonoids present in the crude ethanolic extract and ethyl acetate fraction using HPLC-DAD and LC-MSn analysis. The ethanolic extract was partitioned to obtain the ethyl acetate fraction. The analysis of astilbin content also was carried out by HPLC analysis. HPLC-DAD-ESI/MSn analysis of the ethanolic extract and ethyl acetate fraction revealed the presence of eleven peaks in the chromatograms, and all these peaks were identified: taxifolin, eucryphin, astilbin and 3 diastereoisomers, engeletin and 2 diastereoisomers, quercitrin and 2,6,3',4'-tetrahydroxy-2-benzylcoumaran-3-one. The ethyl acetate fraction had a higher astilbin concentration (151.87 µg/mL) than the ethanolic extract (40.13 µg/mL). In conclusion, the species could be considered a good source of flavonoids, which can be related to the main chemotaxonomic markers for the genus Hymenaea.

description: This paper studies the problem of distributed formation maneuver control of multi-agent systems via complex Laplacian. We will show how to change the translation, scaling, rotation, and also the shape of formation continuously by only tuning the positions of the leaders in both 2-D and 3-D spaces, where the rotation of formation in 3-D space is realized by changing the yaw angle, pitch angle, and roll angle of formation sequentially. Compared with real-Laplacian-based methods, the first advantage of the proposed complex-Laplacian-based approach is that each follower requires fewer neighbors and lesser communication. The second advantage is that non-convex and non-generic nominal configurations are allowed and the uniqueness of the complex-constraint-based target formation can be guaranteed by the non-collocated nominal agents. The third advantage is that more formation shapes can be realized by only tuning the positions of the leaders. Two simulation examples are given to illustrate the theoretical results.

description: Satellite imagery solutions are widely used to study and monitor different regions of the Earth. However, a single satellite image can cover only a limited area. In cases where a larger area of interest is studied, several images must be stitched together to create a single larger image, called a mosaic, that can cover the area. Today, with the increasing number of satellite images available for commercial use, selecting the images to build the mosaic is challenging, especially when the user wants to optimize one or more parameters, such as the total cost and the cloud coverage percentage in the mosaic. More precisely, for this problem the input is an area of interest, several satellite images intersecting the area, a list of requirements relative to the image and the mosaic, such as cloud coverage percentage, image resolution, and a list of objectives to optimize. We contribute to the constraint and mixed integer lineal programming formulation of this new problem, which we call the \textit{satellite image mosaic selection problem}, which is a multi-objective extension of the polygon cover problem. We propose a dataset of realistic and challenging instances, where the images were captured by the satellite constellations SPOT, Pléiades and Pléiades Neo. We evaluate and compare the two proposed models and show their efficiency for large instances, up to 200 images.

Seismic response of tall buildings using ground motions based on National Building Code Canada 2015
Creators: name: Galaviz Gonzalez, Marco Antonio
Publisher: name: University of British Columbia
Year: 2017

description: The seismic analysis of tall buildings requires nonlinear analysis in order to determine their behaviour in a more realistic manner. Nonlinear analysis necessitates the input of suitable ground motions records that represent the hazard at the site of the building. Finding appropriate ground motions is an arduous task, mainly because there are not enough records that are compatible with the hazard level prescribed in the codes for the site of the building. Therefore, existing records must be modified somehow to match the target hazard. The National Building Code of Canada (NBCC) provides guidelines for selecting and scaling ground motions to a target spectrum. This research includes the nonlinear seismic evaluation of a 44-storey concrete building. The structure resembles the characteristics of a typical high-rise in downtown Vancouver. A Probabilistic Seismic Hazard Analysis (PSHA) was performed to determine the governing sources of the site. These seismic sources include crustal, subcrustal and subduction ground motions. The selection and scaling for the three types of earthquakes (crustal, subcrustal and subduction) was performed per the National Building Code Canada 2015. The input of ground motions consisted of 33 pairs of records, 11 of each source. Spectral matching techniques were also employed to match the ground motions to the target spectrum, and the responses between both scaling procedures were compared. The results showed that the subduction records mainly governed the responses of the building. But the responses from the crustal and subcrustal records were also significant and cannot be discarded. It was observed that spectral matching and the code based scaling procedure generated similar responses. In addition, issues with the Code based scaling procedure were addressed.

description: We analysed the IGR J16465-4507 Burst Alert Teelescope survey data collected during the first 54 months of the Swift mission. The source is in a crowded field and it is revealed through an ad hoc imaging analysis at a significance level of ~14 standard deviations. The 15-50 keV average flux is ~3E-11 erg/cm^2/s. The timing analysis reveals an orbital period of 30.243 +/- 0.035 days. The folded light curve shows the presence of a wide phase interval of minimum intensity, lasting ~20% of the orbital period. This could be explained with a full eclipse of the compact object in an extremely eccentric orbit or with the passage of the compact source through a lower density wind at the orbit apastron. The modest dynamical range observed during the BAT monitoring suggests that IGR J16465-4507 is a wind-fed system, continuously accreting from a rather homogeneous wind, and not a member of the Supergiant Fast X-ray Transient class.

description: The boundary-induced phase transitions in an asymmetric simple exclusion process with inter-particle repulsion and bulk non-conservation are analyzed through the fixed points of the boundary layers. This system is known to have phases in which particle density profiles have different kinds of shocks. We show how this boundary-layer fixed-point method allows us to gain physical insights on the nature of the phases and also to obtain several quantitative results on the density profiles especially on the nature of the boundary-layers and shocks.

description: A coated hollow core microsphere is introduced as a novel target in ultra-intense laser-matter interaction experiments. In particular, it facilitates staged laser-driven proton acceleration by combining conventional target normal sheath acceleration (TNSA), power recycling of hot laterally spreading electrons and staging in a very simple and cheap target geometry. During TNSA of protons from one area of the sphere surface, laterally spreading hot electrons form a charge wave. Due to the spherical geometry, this wave refocuses on the opposite side of the sphere, where an opening has been laser micromachined. This leads to a strong transient charge separation field being set up there, which can post-accelerate those TNSA protons passing through the hole at the right time. Experimentally, the feasibility of using such targets is demonstrated. A redistribution is encountered in the experimental proton energy spectra, as predicted by particle-in-cell simulations and attributed to transient fields set up by oscillating currents on the sphere surface.

The experimental values of relative yields were compared with theoretical results obtained on the basis of TALYS with the standard parameters and the combined model of photonucleon reactions. Including isospin splitting in the combined model of photonucleon reactions allows to describe experimental data on reactions with proton escape in energies range from 10 to 23 MeV. Therefore, taking into account isospin splitting is necessary for a correct description of the decay of the GDR.

description: A number of iridoids and triterpene acids, such as pulchelloside, sesamoside, shanshiside methyl ester, barlerin, gypsogenin acid and acetate of gypsogenic acid were isolated from the aerial part of Phlomis linearifolia and their structures were confirmed by NMR, mass and IR spectroscopy. In addition, the hepatoprotective potential of iridoid fraction from P. linearifolia aerial parts was tested against CCl4 induced fibrosis in rats. The iridoid fraction not only prevented the manifestation of the hepatotoxic effect of CCl4, but rather quickly eliminated the effects of developing intoxication. The hepatoprotective activity of the SI was confirmed to be effective and exceeds knows drug carsil.

We thus determine the (p, T) phase diagram of CO in that manganite. We also find that the parameter d(lnTCO)/dp which describes this metallization from the CO phase is equal and opposite to the quantity d(lnTc)/dp which governs the metallization of the paramagnetic state at comparable Curie temperatures Tc, in similar manganites at half doping.

description: Lytic transition of Epstein-Barr virus (EBV) is initiated by distinct immediate early regulators of the viral cycle, in synchronization to temporary, permissive conditions during host cell differentiation. We developed eukaryotic vectors suitable to imitate the processes involved in lytic transition in cell culture systems. Two stable B cell lines were established: R59Z activator cells were used to induce lytic EBV expression in a constitutive manner by the production of the BZLF 1 trans-activator (Zta). R7-57 reporter cells, on the other hand, signaled induced activity of the lytic origin of EBV replication (ori Lyt). Different modes, like chemical induction, lytic superinfection with EBV and single gene trans-activation converted the recombinant ori Lyt element in R7-57 reporter cells. BZLF 1, transiently expressed in R7-57 reporter cells, was the only EBV trans-activator found, sufficient in inducing the viral lytic cycle. Basing on these experiments, trans-cellular activation of EBV was tested by cocultivation of BZLF 1-expressing R59Z activator cells with the R7-57 reporter line. No lytic effect on the reporter cells could be measured, neither by cocultivation of activator cells nor by coincubation of BZLF 1-containing cell lysates. Latency breaking activity, however, was transferred from activator to reporter cells when active, exogenous virus was added. The cell system described in these experiments provides a tool for the detection of EBV reactivation and demonstrates the potential of the lytic regulatory gene BZLF 1.

description: Development of natural nano-based plant-protection formulations represents an emerging phenomenon that has been widely improved for crops protection and for enhancing the efficiency and safety of pesticides. In the present study we isolated the essential oil from the fruits of Citrus trifoliata L. and investigated it using gas chromatography-mass spectrometry analysis. Limonene (78.46%) was the major component followed by β-Myrcene (7.94%) and Caryophyllene (4.20%). Citrus trifoliata essential oil (CTEO) loaded nano-cubosomes were successfully prepared by the emulsification technique. The insecticidal and fungicidal activities of formulated CTEO nano-cubosomes and unformulated CTEO were tested. While both of them exhibited substantial activities, CTEO nano-cubosomes were more effective than unformulated oil. It is the first time to formulate CTEO in nano-cubosomes and examine their insecticidal and fungicidal activities. In light of the current study, CTEO as it is or as nano-cubosomes is recommended as a promising candidate for pest and fungal pathogens control.

Modelling sediment dynamics at the basin scale : implications of changes in climate and hydrological regimes
Creators: name: Tsuruta, Kai
Publisher: name: University of British Columbia
Year: 2019

description: Basin-wide sediment dynamics are closely linked to hydrological processes and landscape and therefore expected to be susceptible to climate change. Simulating sediment transport through large basins presents a challenging problem to modellers; the relationship between water flux and sediment load is complex and non-linear, and significant sediment generation can occur over small spatial and time scales. To date, most studies have employed lumped empirical models that predict annual load at the outlet of a study basin, but do not consider variability across the basin or sub-annually. In this study, we adapt a physically-based, distributed suspended sediment transport model for large-scale use. The sediment model is integrated into the Terrestrial Hydrology Model with Biochemistry (THMB) as a routine to make use of THMB’s dynamic water routing. The coupled model is applied to the 230,000 km² Fraser River Basin (FRB) in British Columbia, Canada using 1) historical hydrological input to test the model and 2) synthetic input derived from Intergovernmental Panel on Climate Change (IPCC) scenarios A1B, A2, and B1 to study potential impacts of climate change. In both cases the input data is provided by the Pacific Climate Impacts Consortium (PCIC) and comes from simulations using the Variable Infiltration Capacity (VIC) model. Simulation results using historical inputs are compared with observations at five stations using the coefficient of determination (R²), Nash-Sutcliffe coefficient of efficiency (NSE), and percent bias (PBIAS) metrics. Overall, simulated load values match well with observed values, with the monthly simulations at the station nearest the outlet scoring R² = 0.78, NSE = 0.77, and PBIAS = -20%. Simulation results using climate scenario-driven inputs are studied for potential future changes in sediment dynamics. Results re- veal a general shift in hillslope erosion and sediment yield towards larger values from autumn to spring, reduced summer values, and an overall annual increase, with hillslope generation growing 35-45% from baseline levels and yield at the basin’s outlet increasing 10-15%. These physically-based results offer unique insights into the impacts of climate change on sediment processes within a large basin and their potential implications.

description: Polarized neutron reflectometry is used to study the magnetic proximity effect in a superconductor/ferromagnet (SC/FM) system of composition Cu(32nm)/V(40nm)/Fe(1nm)/MgO. In contrast to previous studies, here a single SC/FM bilayer, is studied and multilayer artefacts are excluded. The necessary signal enhancement is achieved by waveguide resonance, i.e. preparing the V(40nm)/Fe(1nm) SC/FM bilayer sandwiched by the highly reflective MgO substrate and Cu top layer, respectively . A new magnetic state of the system was observed at temperatures below 0.7 TC. manifested in a systematic change in the height and width of the waveguide resonance peak. Upon increasing the temperature from 0.7 TC to TC, a gradual decay of this state is observed, accompanied by a 5% growth of the diffuse scattering. According to theoretical studies, such behavior is the result of the magnetic proximity effect. Due to the presence of the thin FM layer the superconducting electrons are polarized and, as a result, near the SC/FM interface an additional magnetic layer appears in the SC with thickness comparable to ksi, the coherence length of the superconductor.

description: The growth of a crystal is usually determined by its surface. Many factors influence the growth dynamics. Energy barriers associated with the presence of steps most often decide about the emerging pattern. The height and type of Ehrlich-Schwoebel step barriers lead to the growth of nanocolumns, nanowires, pyramids, and bunches or meanders in the same system. Surface diffusion is another factor that determines the nature of growth. We used the (2+1)D cellular automaton model to investigate the additional effect of diffusion along with step barriers. We show that when we only change the diffusion rate, the length of the meanders or the height of the bunches increase, while the cracked structure of the nanopillars changes into very long, tall nanowires. We show that the length of the step-step correlation is a good characterization of the resulting patterns.

description: A diketopiperazine (3S, 6S)-3,6-diisobutylpiperazine-2,5-dione was isolated from a sponge-associated microbe for the first time and characterized by FTIR, HRESI-MS, 1H, 13C NMR and 2D NMR. The source is novel for this compound. Single crystal XRD of this diketopiperazine obtained as a natural product was analysed for the first time and its melting point was determined to be 262 °C. MICs of this cyclic dipeptide against Escherichia coli and Staphylococcus aureus subsp. aureus were 16 µg mL−1 and 22 µg mL−1 respectively, the first report of antibacterial activity of this diketopiperazine.

description: The incidence of skin cancer, in particular melanoma, has been steadily increasing over the past few decades. Early-stage melanoma often exhibits minimal symptoms, making it challenging to detect. However, when it progresses to later stages and spreads to the lymph nodes, the chances of survival significantly decrease. The current diagnostic gold standard involves invasive and time-consuming procedures, such as visual examination, excision, and histological examination of tissue samples. To solve this problem, a new multimodal optical system was developed that addresses these challenges by integrating ultrasound (US), photoacoustic tomography (PAT), optical coherence tomography (OCT) and Raman spectroscopy (RS) into a single measurement unit. The OCT modality delivers detailed structural and depth information for thin skin lesions. Meanwhile, ultrasound (US) and photoacoustic tomography (PAT) enable the assessment of penetration depth of thicker lesions. Raman spectroscopy analyzes the chemical composition of skin lesions, aiding in the differentiation between benign and malignant cases. This work describes the system that was developed during the project, including the conceptualization, construction, programming and characterization. The imaging capabilities of the system were demonstrated through measurements on custom-made agar phantoms and ex vivo melanoma samples. Additionally, the clinical capability of the system was demonstrated with in vivo results on human skin, which were obtained at the University Medical Center Rostock.

description: Development of natural nano-based plant-protection formulations represents an emerging phenomenon that has been widely improved for crops protection and for enhancing the efficiency and safety of pesticides. In the present study we isolated the essential oil from the fruits of Citrus trifoliata L. and investigated it using gas chromatography-mass spectrometry analysis. Limonene (78.46%) was the major component followed by β-Myrcene (7.94%) and Caryophyllene (4.20%). Citrus trifoliata essential oil (CTEO) loaded nano-cubosomes were successfully prepared by the emulsification technique. The insecticidal and fungicidal activities of formulated CTEO nano-cubosomes and unformulated CTEO were tested. While both of them exhibited substantial activities, CTEO nano-cubosomes were more effective than unformulated oil. It is the first time to formulate CTEO in nano-cubosomes and examine their insecticidal and fungicidal activities. In light of the current study, CTEO as it is or as nano-cubosomes is recommended as a promising candidate for pest and fungal pathogens control.

description: In cultural heritage, several initiatives are promoted to transfer the green chemistry in replacing traditional and toxic methods and products, and in ensuring safety of both artworks and restorers during cleaning operations. This study is aimed to establish the validity of new green solvents to replace toxic solvents, commonly used, to remove old paint varnishes. In particular, the research is focused on the use of acetals to remove old varnishes paintings. The acetals are common functional groups in natural products which are generated by reactions between alcohols and aldehydes. The tests were performed on four different resins (DAMAR, RETOUCHER, PVA and PMMA). Several samples were prepared to reproduce the common stratigraphy succession of the oil painting. The performances of the solvents were monitored by visible light/UV light, photography and optical microscopy, spectro-colorimetric analysis. Then, FTIR spectra of the cleaned surface have been acquired to detect the residues after cleaning.

description: In a mobile ad hoc network, temporary link failures and route changes occur frequently. With the assumption that all packet losses are due to congestion, TCP performs poorly in such an environment. There are many versions of TCP which modified time to time as per need. In this paper modifications introduced on TCP New Reno over mobile ad-hoc networks using calculation of New Retransmission Time out (RTO), to improve performance in term of congestion control. To calculate New RTO, adaptive backoff response approach (ABRA) in TCP New Reno was applied which suggest ABRA New Reno. It utilizes an ABRA by which congestion window and slow start threshold values were decreased whenever an acknowledgement is received and new backoff value calculate from smoothed round trip time. Evaluation based on comparative study of ABRA New Reno with other TCP Variants like New Reno and Reno was done using realistic parameters like TCP Packet Received, Packet Drop, Packets Retransmitted, Throughput, and Packet Delivery Ratio calculated by varying attributes of Node Speed, Number of Nodes and Pause Time. Implementation and simulations were performed in QualNet 4.0 simulator.
Smart electronic loads for harmonic compensation in future electrical distribution systems
Creators: name: Chang, Hua
Publisher: name: University of British Columbia
Year: 2017

description: Common solutions to mitigating harmonics and improving power quality of power systems would include installing dedicated passive or active harmonic filters at the point of common coupling (PCC). However, as the complexity of energy systems increases with integration of renewables and storage systems on the one side, and the number of electronic loads increases rapidly on the other, the centralized compensation of harmonics may not be cost effective. At the same time, many modern loads and energy sources have high–bandwidth front–end power converters that present an opportunity for alternative solutions to improve power quality. This thesis presents a new methodology to compensate harmonics. Utilizing widely deployed smart meters, the measured information of harmonics can be transmitted in real time through the internet to smart electronic loads, where the loads can inject out–of–phase harmonics for compensation in a distributed fashion. First, this thesis investigates the feasibility of using smart meter measurements in the Fred Kaiser Building on the University of British Columbia (UBC) Vancouver campus, which are then used to demonstrate potential harmonic compensation using installed grid–tied converters. Next, since many modern single–phase electronic loads include a power factor correction (PFC) stage, this thesis develops a PFC controller algorithm to inject typical harmonics (i.e. 3rd, 5th, and 7th) at different levels and phase angles for compensation. This concept is further extended to smart LED drivers that also have a PFC stage, which are envisioned to have advanced power quality features. Such smart electronic loads and LED drivers can be integrated into future distribution systems of residential/commercial buildings, microgrids, etc., with distributed controls and communications through Internet of Things (IoT)/advanced user interfaces.

description: The buckling instability of micro- and nanopillars can be an issue when designing intelligent miniaturized devices and characterizing composite materials reinforced with beam-like particles on the small-scale. Analytical modeling of the buckling of miniaturized pillars is especially important due to the difficulties in conducting experiments. Here, a well-posed stress-driven nonlocal model is developed, which allows the calculation of the critical loads and buckling configurations of the miniaturized pillars on an elastic foundation and with arbitrary numbers of edge cracks. The discontinuities in bending slopes and deflection at the damaged cross-sections due to the edge cracks are captured through the incorporation of both rotational and translational springs. A comprehensive analysis is conducted to investigate the instability of pillars containing a range of one to four cracks. This analysis reveals interesting effects regarding the influence of crack location, nonlocality, and elastic foundation on the initial and subsequent critical loads and associated buckling configurations. The main findings are: (i) the shielding and amplification effects related to a system of cracks become more significant as the dimensions of pillars reduce, (ii) the influence of the shear force at the damaged cross-section related to the translational spring must not be neglected when dealing with higher modes of buckling and long cracks, (iii) an elastic foundation decreases the effects of the cracks and size dependency on the buckling loads, and (iv) the effects of the edge cracks on the critical loads and buckling configurations of the miniaturized pillars are highly dependent on the boundary conditions.

description: This short review summarizes recent developments and results in connection with point-form dynamics of relativistic quantum systems. We discuss a Poincare invariant multichannel formalism which describes particle production and annihilation via vertex interactions that are derived from field theoretical interaction densities. We sketch how this rather general formalism can be used to derive electromagnetic form factors of confined quark-antiquark systems. As a further application it is explained how the chiral constituent quark model leads to hadronic states that can be considered as bare hadrons dressed by meson loops. Within this approach hadron resonances acquire a finite (non-perturbative) decay width. We will also discuss the point-form dynamics of quantum fields. After recalling basic facts of the free-field case we will address some quantum field theoretical problems for which canonical quantization on a space-time hyperboloid could be advantageous.

description: This study made it possible to characterise by GC (in combination with retention indices), GC-MS and 13C NMR, the chemical composition of the essential oils from Solanum rugosum and Solanum erianthum, two Solanaceae of the Ivorian flora. The two essential oils were characterised by a very high proportion of sesquiterpenes. Specifically, the essential oil of S. rugosum was dominated by (E)-β-caryophyllene (33.7%), β-elemol (19.8%) and germacrene D (14.4%), while that of S. erianthum was mainly composed of α-humulene (38.6%), β-elemol (17.8%) and (E)-β-caryophyllene (16.7%). The chemical composition of Solanum rugosum is described here for the first time.
