description: We investigate the unique properties of various analytical optical modes, including the fundamental modes and the excited modes, in a double-channel waveguide with parity-time (PT) symmetry. Based on these optical modes, the dependence of the threshold values for the gain/loss parameter, i.e., PT symmetry breaking points, on the structure parameters is discussed. We find that the threshold value for the excited modes is larger than that of the fundamental mode. In addition, the beam dynamics in the double-channel waveguide with PT symmetry is also investigated.

description: New Approaches to Solar Flare Forecasts

This poster presented at the European Space Weather Week 2023, Toulouse, discuss :

a deep learning model able to forecasts flare at regional levels while only using full-disk labels during training, thus bypassing the misslables issues encountered for flare forecasting at Active Region levels

general limitations of flare forecasting models, mainly their inability to foreccast changes of ativity and underperformances compared to persistent models, along with tailored evalation approaches to highlight such limitations

new labels based on SXR-fluence to better characterize flare activity in large time - windows and provide valuable information on radiation exposure

description: Ethanol extract from the aerial parts of Euphorbia tirucalli L. as well as the latex of the plant suspended in water are used by the Brazilian population for the treatment of various diseases, including cancer. The purposes of this study were to determine if the ethanol extract is effective as cytotoxic agent against gastric adenocarcinoma cells (AGS) and its chemical composition by GC-MS, ESI-(-)-FT-ICR MS and (-)-ESI-LTQ-MS/MS. The results were compared with that of latex previously described by us. Hexane and aqueous fractions showed higher cytotoxicity on AGS cells. Nine triterpene compounds were detected by GC-MS in hexane fraction, including euphol and friedelin, while ellagic acid was identified as main phenolic compound in aqueous extract. Therefore, the greater cytotoxic activity of the ethanol extract of the aerial parts of Euphorbia tirucalli for gastric cancer, when compared to latex, seems to originate from the antiproliferative effects of ellagic acid and triterpenes.

description: This study investigated the elicitation effects of several methyl jasmonate (MeJ) concentrations (0, 25, 50, and 100 µM) on various biochemical traits of caraway (Carum carvi L.) callus cultures. The 25 μM MeJ concentration yielded the highest callus growth rate (0.57 mm day−1), total flavonols content (2.58 mg QE g−1 FW) and total carotenoids content (0.04 μg g−1 FW), whereas the highest relative fresh weight (75.72%), total phenolics content (76.90 mg GAE g−1 FW), total flavonoids content (58.49 mg QE g−1 FW) and phenylalanine ammonia lyase activity (3.40 nmol cinnamic acid mg−1 h−1 FW) were obtained with the 50 μM MeJ concentration. The highest antioxidant activity through DPPH assay (8.37%) and malondialdehyde content (7.82 μmol g−1 FW) were observed at 100 μM MeJ. The HPLC conducted 21 days post-elicitation revealed a 5.55-fold increase of carvone accumulation (1.83 μg g−1 DW) at 50 μM MeJ and a 2.7-fold increase (0.62 μg g−1 DW) of limonene at 50 μM MeJ. The optimal dosages applied for carvone and limonene accumulation under MeJ elicitation could be used to scale up the economic production of these elite medicinal compounds through caraway callus cultures.
A morphological study of cluster dynamics between critical points

description: We study the geometric properties of a system initially in equilibrium at a critical point that is suddenly quenched to another critical point and subsequently evolves towards the new equilibrium state. We focus on the bidimensional Ising model and we use numerical methods to characterize the morphological and statistical properties of spin and Fortuin-Kasteleyn clusters during the critical evolution. The analysis of the dynamics of an out of equilibrium interface is also performed. We show that the small scale properties, smaller than the target critical growing length $ξ(t) \sim t^{1/z}$ with $z$ the dynamic exponent, are characterized by equilibrium at the working critical point, while the large scale properties, larger than the critical growing length, are those of the initial critical point. These features are similar to what was found for sub-critical quenches. We argue that quenches between critical points could be amenable to a more detailed analytical description.

description: The Kondo effect and the Fano-Kondo effect are important phenomena that have been observed in quantum dots (QDs). We theoretically investigate the transport properties of a coupled QD system in order to study the possibility of detecting a qubit state from the modulation of the conductance peak in the Kondo effect and the dip in the Fano-Kondo effect. We show that the peak and dip of the conductance are both shifted depending on the energy-level of the qubit. In particular, we find that we can estimate the optimal point and tunneling coupling between the |0> and |1> states of the qubit by measuring the shift of the positions of the conductance peak and dip, as functions of the applied gate voltage on the qubit and the distance between the qubit and the detector.

description: Discovering the function of genes/proteins is the key to scientific breakthroughs in the field of medicine and biology, impacting billions of lives. However, the current paradigm of discovery relies on experimentations, which increases the time (up to months!) and cost with low scalability option. We are working towards developing computational methods which can predict the function of a protein quickly, economically with the possibility of annotating hundreds of proteins per day. To that goal, we developed Phylo-PFP, a phylogenetic-based method, which combines statistical tools with biological concepts and leverages the power of big data to predict functional terms for any protein. We showed that our method performance is better than other similar methods which were evaluated on a world-wide protein function competition. We have collaborated with multiple experimental teams that have thousands of new genes/proteins, using our tools to uncover their functions, seeking new and interesting proteins.

description: The Great War required war-making states to mobilize and sustain the financial resources for a global war on an unprecedented scale. What made war finance during the conflict so special is that this challenge had never been confronted in a world economy as large, deeply interconnected, and sophisticated as that which existed in 1914. This article outlines the monetary politics of the global “system” of war finance. It will incorporate perspectives on national economies, but integrates these to sketch the international and transnational aspects of financing the war. The article sets out the basic elements of the pre-war financial system and its global dynamics; examines the different modes of war finance adopted by the belligerents; considers the Central Powers and the Entente as financial alliances operating in the global monetary system; describes the interaction of public and private entities; and surveys the long-term consequences of war finance on the world economy.

description: The chemical investigation of the methanolic root extract of Flacourtia vogelii led to the isolation of a new arylbenzoate derivative, vogelinal (1), together with thirteen known compounds (2–14). The structures of the isolates were elucidated by extensive spectroscopic and spectrometric analyses (1D and 2D NMR, ESI-MS) and by comparison with previously reported data. All the compounds were tested for their antioxidant, antifungal and antibacterial activities. Compound 7 exhibited the highest antioxidant potential, with RSa50of 11.80 ± 2.13 µg/mL, RSa50of 42.60 ± 6.32 µg/mL and RC50 of 51.60 ± 7.71 µg/mL for the DPPH, ABTS and FRAP assay, respectively. Compound 13 displayed weak antifungal effect with MIC value of 125 μg/mL against Candida parapsilosis. Compound 8 showed weak antibacterial effect with MIC value of 125 μg/mL, against Shigella dysenteria. The present study, conclude that this species could be a promising source of antioxidant and antibacterial constituents.

Identifying critical information for nursing handover : designing a nurse to nurse handover form
Creators: name: Chalke, Nicola Jane
Publisher: name: University of British Columbia
Year: 2014

description: Patient handover represents a significant safety risk. At each handover information could be lost, misinterpreted or not well communicated. Patient handover refers to any time responsibility for a patient’s care is transferred from one care provider to another. This process requires succinct communication between the care providers, in this case nurses, to ensure continuity and safety of patient care. A significant handover that occurs daily on any nursing unit is the handover that occurs between nursing shifts: the off-going nurse reports to the oncoming nurse. The purpose of this research was to use an appreciative inquiry process to answer the question: what is the critical information that should be included in a nurse-to-nurse inter-shift report on an acute medical unit at a tertiary, urban teaching hospital? A purposive sample of nurses from the study unit worked together over three separate project group meetings to develop, pilot and refine a new handover form. The 4 D process of the appreciative inquiry method was used including: discover, dream, design and deliver. Thematic analysis was used for each cycle of the apprecitive inquiry process and the main themes found are presented. The central findings from this project include developing a handover form that presents succinct, organized, objective and written information that focuses on the critical events or information from the previous twelve hours and what needs to happen in the next twelve hours. To ensure appropriate use of the form the purpose of the form should be emphasized to all staff and connected to patient safety and continuity of care. In addition, the team discussed implementing a formal and informal feedback process to further encourage appropriate use of the form. Finally, promoting professional accountability to ensure completion of the handover form and accompanying documentation, such as the kardex and careplans.

description: We tested in vivo anti-herpetic effect of castalagin, an ellagitannin compound, extracted from pedunculate oak (Quercus robur). Previous investigations found that castalagin possesses a strong inhibitory effect in vitro against HSV-1/2 equal to acyclovir (ACV). It is also effective against ACV-resistant mutants and shows a synergistic effect with ACV. We study castalagin’s activity towards HSV-1 infection in newborn mice. Acute toxicity determination in mice showed LD50 value of 295 mg/kg. Prolonged toxicity was also constructed. Castalagin manifested a marked activity against HSV-1 (LD90/0.02 ml) administered in 7-day course at 0.02 ml s.c. doses of 7.5 or 10 mg/kg (PI 57-58%). ACV course demonstrated a marked activity at 20 mg/kg. The selectivity ratio LD50/ED50 (295/7.5) could be accepted as ≥ 33.

description: We show that for a wide class of manifold pairs N, M satisfying dim(M) = dim(N) + 1, every π_1-injective map f : N --> M factorises up to homotopy as a finite cover of an embedding. This result, in the spirit of Waldhausen's torus theorem, is derived using Cappell's surgery methods from a new algebraic splitting theorem for Poincare duality groups. As an application we derive a new obstruction to the existence of π_1-injective maps.

Multimodal biomedical signal processing for corticomuscular coupling analysis
Creators: name: Chen, Xun
Publisher: name: University of British Columbia
Year: 2014

description: Corticomuscular coupling analysis using multiple data sets such as electroencepha-logram (EEG) and electromyogram (EMG) signals provides a useful tool for understanding human motor control systems. A popular conventional method to assess corticomuscular coupling is the pair-wise magnitude-squared coherence (MSC). However, there are certain limitations associated with MSC, including the difficulty in robustly assessing group inference, only dealing with two types of data sets simultaneously and the biologically implausible assumption of pair-wise interactions. In this thesis, we propose several novel signal processing techniques to overcome the disadvantages of current coupling analysis methods. We propose combining partial least squares (PLS) and canonical correlation analysis (CCA) to take advantage of both techniques to ensure that the extracted components are maximally correlated across two data sets and meanwhile can well explain the information within each data set. Furthermore, we propose jointly incorporating response-relevance and statistical independence into a multi-objective optimization function, meaningfully combining the goals of independent component analysis (ICA) and PLS under the same mathematical umbrella. In addition, we extend the coupling analysis to multiple data sets by proposing a joint multimodal group analysis framework. Finally, to acquire independent components but not just uncorrelated ones, we improve the multimodal framework by exploiting the complementary property of multiset canonical correlation analysis (M-CCA) and joint ICA. Simulations show that our proposed methods can achieve superior performances than conventional approaches. We also apply the proposed methods to concurrent EEG, EMG and behavior data collected in a Parkinson's disease (PD) study. The results reveal highly correlated temporal patterns among the multimodal signals and corresponding spatial activation patterns. In addition to the expected motor areas, the corresponding spatial activation patterns demonstrate enhanced occipital connectivity in PD subjects, consistent with previous medical findings.

description: The ethanol extract of the fungus Sarcodon scabripes collected from north-central British Columbia, Canada, showed strong antiproliferative activity. Bioassay-guided purification using liquid-liquid extraction and Sephadex LH-20 size-exclusion chromatography, followed by HPLC-MS and 1D/2D NMR analyses, led to the isolation of five known compounds; four p-terphenyl (1-4) derivatives and one phenolic aldehyde (5). Compounds 1, 4, and 5 were isolated for the first time from the Sarcodon genus. The cytotoxicity MTT assay showed that compounds 1-5 have antiproliferative activity against human cervical cancer cells (HeLa). For compounds 1-4, this is the first report of their antiproliferative activity against cancer cells. For compound 2, this is the first report on its bioactivity. To our knowledge, this is the first description of the isolation of bioactive constituents from S. scabripes.

Sweet leaves was performed in-vitro using α-glucosidase and α-amylase inhibition methods. Phytochemical study of the ethyl acetate fraction which possessed the highest antidiabetic activity led to isolation of five flavonoids for the first time from this plant, including two rare flavonoid sulphates, ombuin-3-sulphate [1] and rhamnetin-3-sulphate [2] and three flavonoid glycosides, kaempferol 7-O-α-L-rhamnopyranoside [3], kaempferol 3,7-di-O-α-L-rhamnopyranoside [4] and quercetin 3-O-α-L-arabinopyranoside [5]. The 1H and 13C NMR of 1 and 13C NMR of 2, were reported here for the first time. Compounds [1-4] showed a concentration-dependent in-vitro inhibitory activity against α-glucosidase and α-amylase. Furthermore, in-silico study predicted that compounds (1-5) showed good interactions with α-glucosidase, α-amylase, and protein tyrosine phosphatase 1b.

description: We derive a formula for the global gravitational anomaly of the self-dual field theory on an arbitrary compact oriented Riemannian manifold. Along the way, we uncover interesting links between the theory of determinant line bundles of Dirac operators, Siegel theta functions and a functor constructed by Hopkins and Singer. We apply our result to type IIB supergravity and show that in the naive approximation where the Ramond-Ramond fields are treated as differential cohomology classes, the global gravitational anomaly vanishes on all 10-dimensional spin manifolds. We sketch a few other important physical applications.

description: We study the restoration of spontaneously broken symmetry at nonzero temperature in the framework of the O(2) model using polar coordinates. We apply the CJT formalism to calculate the masses and the condensate in the double-bubble approximation, both with and without a term that explicitly breaks the O(2) symmetry. We find that, in the case with explicitly broken symmetry, the mass of the angular degree of freedom becomes tachyonic above a temperature of about 300 MeV. Taking the term that explicitly breaks the symmetry to be infinitesimally small, we find that the Goldstone theorem is respected below the critical temperature. However, this limit cannot be performed for temperatures above the phase transition. We find that, no matter whether we break the symmetry explicitly or not, there is no region of temperature in which the radial and the angular degree of freedom become degenerate in mass. These results hold also when the mass of the radial mode is sent to infinity.

description: One new compound, 4,7-dihydroxy-2-hydroxymethyl-5,6-dimethoxyanthraquinone (1), along with eight known compounds (2–9) were isolated from the methanol extracts of the aerial parts of Chamaecrista pumila (Lam.) K. Larsen. Their chemical structure was determined based on spectroscopic data interpretation and comparison with the reported data. The inhibitory effects of them on α-amylase and α-glucosidase were performed. The results showed that compounds 4, 6, 8, and 9 against potent α-glucosidase with the inhibition values of 98.14 ± 0.05, 98.19 ± 0.04, 97.01 ± 0.49, 84.43 ± 0.6% at 50 µM, respectively. Compounds 4 and 6 displayed significance against α-amylase at 200 µM with inhibition values of 22.35 ± 1.10 and 60.47 ± 0.91%.

On the accuracy of the Debye shielding

description: The expression for the Debye shielding in plasma physics is usually derived under the assumptions that the plasma particles are weakly coupled, so their kinetic energy is much larger than the potential energy between them, and that the velocity distributions of the plasma species are Maxwellian. The first assumption also establishes that the plasma parameter ND, the number of particles within a sphere with a Debye radius should be greater than 1, and determines the difference between weakly and strongly coupled plasmas. Under such assumptions, Poisson's equation can be linearised, and a simple analytic expression obtained for the electrostatic potential. However, textbooks rarely discuss the accuracy of this approximation. In this work we compare the linearised solution with the exact one, obtained numerically, and show that the linearisation, which underestimates the exact solution, is reasonably good even for ND ~ 40. We give quantitative criteria to set the limit of the approximation when the number of particles is very small, or the distance to the test charge too short.

Particulate fouling by iron oxide at elevated temperatures : surface chemistry, interfacial electrochemistry and sensor development
Creators: name: Zebardast, Hamidreza
Publisher: name: University of British Columbia
Year: 2014

description: Particulate fouling as a result of corrosion product sedimentation is known to be a significant issue in the heat exchanger of nuclear power plants and thus the development of monitoring technologies for the detection of fouling is important. Since electrochemical processes are usually very sensitive to water chemistry, they provide an opportunity for the development of accurate and online sensors. The main aim of this work is to develop an electrochemical sensor to detect particulate fouling at various temperatures and pressures up to 200 ºC. In order to develop such an electrochemical sensor, knowledge of the interfacial chemistry and electrochemistry of both the suspended particles and the sensing probe are required. Potentiometric titration was used to measure the pH of zero charge (PHZC) of magnetite and hematite (both known particulate foulants) from 25 ºC to 200 ºC. Electrochemical impedance spectroscopy (EIS) was used to measure the minimum differential capacitance of a glassy carbon electrode (GC) as a function of electrode potential i.e. the potential of zero charge (PZC). The obtained results clarified the oxide particle-electrode interaction since a GC electrode was used as a detector probe. A sensor for particulate fouling detection was then investigated and a new experimental method for the detection of magnetite particles at temperatures up to 200 ºC was developed. An electromagnetic GC electrode was employed to collect the magnetite particles from the suspension solution and it was observed that changes in double-layer capacitance could be used to detect deposition at different conditions. Finally, the impact of particulate fouling on water chemistry was studied. A novel electrochemical method was employed to accurately measure the kinetics of H2O2 decomposition on the surface of magnetite at temperatures up to 200 ºC. This work provides an experimental methodology for the prediction of failures due to particulate fouling processes in heat exchangers by providing a means to estimate the extent of fouling, the interactions between colloidal foulants and their corresponding impact on water chemistry.
Long-term stability of sequential Monte Carlo methods under verifiable conditions

description: This paper discusses particle filtering in general hidden Markov models (HMMs) and presents novel theoretical results on the long-term stability of bootstrap-type particle filters. More specifically, we establish that the asymptotic variance of the Monte Carlo estimates produced by the bootstrap filter is uniformly bounded in time. On the contrary to most previous results of this type, which in general presuppose that the state space of the hidden state process is compact (an assumption that is rarely satisfied in practice), our very mild assumptions are satisfied for a large class of HMMs with possibly noncompact state space. In addition, we derive a similar time uniform bound on the asymptotic $\mathsf{L}^p$ error. Importantly, our results hold for misspecified models; that is, we do not at all assume that the data entering into the particle filter originate from the model governing the dynamics of the particles or not even from an HMM.

description: High energy density (HED) matter is defined as having an energy density above $10^{11}$ $J•m^{-3}$, which is equivalent to 100 GPa (1 Mbar) pressure and 500 T magnetic pressure. The scientific objectives of the High Energy Density Physics instrument (HED instrument) at the European XFEL are to create and explore HED states using the particular features of X-ray free-electron laser (FEL) radiation. Strongly excited solid but below-HED states are also considered to be a key science area, as such transient states are precursors to the formation of HED states in laboratory experiments. This report describes the conceptual design of the HED instrument at the European XFEL. The HED instrument will be one of the six baseline instruments of the facility. It will provide to a wide community of condensed-matter, plasma, and high-power laser physicists a scientific instrument for experiments not possible anywhere else in the world.This report is based on the requirements emerging from the scientific objectives of the HED instrument and the anticipated X-ray techniques to be fielded at this instrument. Major subsystems of the HED instrument are described, including the beam transport elements, the instrument components, and the requirements for further subsystems and infrastructure. Furthermore, the interfaces of the HED instrument to other work packages of the European XFEL project are described with the goal of realizing a highly integrated project.
