description: Consider N equally-spaced points on a circle of circumference N. Choose at random n points out of $N$ on this circle and append clockwise an arc of integral length k to each such point. The resulting random set is made of a random number of connected components. Questions such as the evaluation of the probability of random covering and parking configurations, number and length of the gaps are addressed. They are the discrete versions of similar problems raised in the continuum. For each value of k, asymptotic results are presented when n,N both go to infinity according to two different regimes. This model may equivalently be viewed as a random partitioning problem of N items into n recipients. A grand-canonical balls in boxes approach is also supplied, giving some insight into the multiplicities of the box filling amounts or spacings. The latter model is a k-nearest neighbor random graph with N vertices and kn edges. We shall also briefly consider the covering problem in the context of a random graph model with N vertices and n (out-degree 1) edges whose endpoints are no more bound to be neighbors.

description: The energy density and angular distribution of power radiated by a quark undergoing circular motion in strongly coupled ${\cal N}=4$ supersymmetric Yang-Mills (SYM) theory is computed using gauge/gravity duality. The results are qualitatively similar to that of synchrotron radiation produced by an electron in circular motion in classical electrodynamics: At large velocities the quark emits radiation in a narrow beam along its velocity vector with a characteristic opening angle $α\sim 1/γ$ and radial thickness scaling like $\sim 1/γ^3$.

description: We investigate the stability of Quantum Critical Points (QCPs) in the presence of two competing phases. These phases near QCPs are assumed to be either classical or quantum and assumed to repulsively interact via square-square interactions. We find that for any dynamical exponents and for any dimensionality strong enough interaction renders QCPs unstable, and drives transitions to become first order. We propose that this instability and the onset of first-order transitions lead to spatially inhomogeneous states in practical materials near putative QCPs. Our analysis also leads us to suggest that there is a breakdown of Conformal Field Theory (CFT) scaling in the Anti de Sitter models, and in fact these models contain first-order transitions in the strong coupling limit.

On tight Euclidean $6$-designs: an experimental result

description: A finite set $X \seq \RR^n$ with a weight function $w : X \longrightarrow \RR_{>0}$ is called \emph{Euclidean $t$-design} in $\RR^n$ (supported by $p$ concentric spheres) if the following condition holds: \[ \sum_{i=1}^p \frac{w(X_i)}{|S_i|}\int_{S_i} f(\boldsymbol x)dσ_i(\boldsymbol x) =\sum_{\boldsymbol x \in X}w(\boldsymbol x) f(\boldsymbol x), \] for any polynomial $f(\boldsymbol x) \in \mbox{Pol}(\RR^n)$ of degree at most $t$. Here $S_i \seq \RR^n$ is a sphere of radius $r_i \geq 0,$ $X_i=X \cap S_i,$ and $σ_i(\boldsymbol x)$ is an $O(n)$-invariant measure on $S_i$ such that $|S_i|=r_i^{n-1}|S^{n-1}|$, with $|S_i|$ is the surface area of $S_i$ and $|S^{n-1}|$ is a surface area of the unit sphere in $\RR^n$. Recently, Bajnok (2006) constructed tight Euclidean $t$-designs in the plane ($n=2$) for arbitrary $t$ and $p.$ In this paper we show that for case $t=6$ and $p=2,$ tight Euclidean $6$-designs constructed by Bajnok is the unique configuration in $\RR^n$, for $2 \leq n \leq 8.$

description: Within the context of 5-axis free-form machining, CAM software offers various ways of tool-path generation, depending on the geometry of the surface to be machined. Therefore, as the manufactured surface quality results from the choice of the machining strategy and machining parameters, the prediction of surface roughness in function of the machining conditions is an important issue in 5-axis machining. The objective of this paper is to propose a simulation model of material removal in 5-axis based on the N-buffer method and integrating the Inverse Kinematics Transformation. The tooth track is linked with the velocity giving the surface topography resulting from actual machining conditions. The model is assessed thanks to a series of sweeping over planes according to various tool axis orientations and cutting conditions. 3D surface topography analyses are performed through the new areal surface roughness parameters proposed by recent standards.
Delivery service assortment and product pricing in online retailing : the impact of pricing flexibility and customer rating
Creators: name: Yu, Junhao
Publisher: name: University of British Columbia
Year: 2015

description: This research studies the delivery service assortment and product pricing problem in the context of online retailing where the seller selects a series of delivery options from a set of available alternatives for the customers to choose from and decides the price for the product and the listed surcharge for each delivery service. We aim to examine the impact of seller's pricing flexibility and customer rating on the optimal decisions and the optimal expected profit of the seller. By solving and comparing the results of four related problems, we find that usually it would be optimal for the seller to include all the available delivery options and charge a constant mark-up for all the options. But when the customer rating is aggregated, the seller would have to solve a combinatorial optimization problem to find out the optimal assortment when pricing is restricted to the product only and he should differentiate the mark-up for each option when he enjoys the pricing flexibility to re-price the quoted surcharges. We also show that two simple heuristic algorithms provide very good performance for the mentioned combinatorial optimization problem. We explain why the aggregated rating would only hurt the seller and how pricing flexibility could remove its negative effect while assortment adjustment can only weaken its impact. In addition, numerical studies present the comparison between the two main problems with aggregated customer rating and provide some observations of the impact on delivery service providers and the customers. The findings in this thesis yield useful managerial insights for the delivery service providers as well as the seller for making their strategic decisions.

description: We report the detection of OVI 1031,1037 and NV 1238,1242 absorption in a system of "mini-broad" absorption lines (mini-BALs) previously reported to have variable CIV 1548,1550 in the quasar PG0935+417. The formation of these lines in an extreme high-velocity quasar outflow (with v ~ -50000 km/s) is confirmed by the line variability, broad smooth absorption profiles, and partial covering of the background light source. HI and lower ionization metals are not clearly present. The resolved OVI doublet indicates that these lines are moderately saturated, with the absorber covering ~80% of the quasar continuum source (C_f~0.8). We derive ionic column densities of order 1015 cm^(-2) in CIV and several times larger in OVI, indicating an ionization parameter of log U >~ -0.5. Assuming solar abundances, we estimate a total column density of N(H) ~5 x 10^(19) cm^(-2). This outflow emerged sometime between 1982 and 1993. Our examination of the CIV data from 1993 to 2007 shows that there is variable complex absorption across a range of velocities from -45000 to -54000 km/s. There is no clear evidence for acceleration or deceleration of the outflow gas. Outflows are common in Active Galactic Nuclei (AGN), but extreme speeds such as those reported here are extremely rare. It is not clear what properties of PG0935+417 might produce this unusual outflow. In fact, PG0935+417 has significantly less X-ray absorption than typical BAL quasars even though its outflow has a degree of ionization typical of BALs at speeds that are 2-3 times larger than most BALs. These results might present a challenge to theoretical models that invoke strong radiative shielding in the X-rays/far-UV to moderate the outflow ionization and thus enable its radiative acceleration to high speeds.

description: The quantum well solar cell (QWSC) has been proposed as a route to higher efficiency than that attainable by homojunction devices. Previous studies have established that carriers escape the quantum wells with high efficiency in forward bias and contribute to the photocurrent. Progress in resolving the efficiency limits of these cells has been dogged by the lack of a theoretical model reproducing both the enhanced carrier gen- eration and enhanced recombination due to the quantum wells. Here we present a model which calculates the incremental generation and recombination due to the QWs and is verified by modelling the experimental light and dark current-voltage characteristics of a range of III-V quantum well structures. We find that predicted dark currents are significantly greater than experiment if we use lifetimes derived from homostructure devices. Successful simulation of light and dark currents can be obtained only by introducing a parameter which represents a reduction in the quasi-Fermi level separation.

De plus l’absence de capacité de préhension active ne signifie pas qu’un membre supérieur est « non-fonctionnel », puisque le membre supérieur peut également avoir une position de fonction par l’appui ou le contre-appui, ou même de stabilisation par une préhension passive.

description: This paper focuses on the performance evaluation of the parallel manipulators for milling of composite materials. For this application the most significant performance measurements, which denote the ability of the manipulator for the machining are defined. In this case, optimal synthesis task is solved as a multicriterion optimization problem with respect to the geometric, kinematic, kinetostatic, elastostostatic, dynamic properties. It is shown that stiffness is an important performance factor. Previous models operate with links approximation and calculate stiffness matrix in the neighborhood of initial point. This is a reason why a new way for stiffness matrix calculation is proposed. This method is illustrated in a concrete industrial problem.
Optimization of empty container movements using “street-turn” strategy : application to Metro Vancouver area
Creators: name: Zhang, Hanxing
Publisher: name: University of British Columbia
Year: 2015

description: This paper focuses on the regional empty container repositioning problem. We propose a more practical model to optimize regional empty container movements. With the framework, we evaluate the effectiveness of “street-turn” strategy and provide insights on “street-turn” operation in Metro Vancouver area. We conduct interviews with local industry professionals to collect information about current empty container operations. The major findings from this research are: (1) “Street-turn” strategy reduces empty container repositioning cost majorly from transportation and gate fees. (2) “Street-turn” strategy is more effective in trade-balanced environment than trade-imbalanced environment. (3) The number of participants in the transport network has a positive impact on the feasibility and effectiveness of “street-turn” strategy. (4) The variance in the supply and demand of empty containers increases the variance in the effectiveness of “street-turn” strategy. (5) Container users have higher incentive to promote “street-turn” operations than shipping lines. (6) “Street-turn” strategy has been conducted jointly by a few importers and exporters in Metro Vancouver area. The major challenge is that container information is not shared among participants. (7) Unlike the situation in LA/LB port region, shipping lines have not yet taken the initiative to promote “street-turn” interchanges in Metro Vancouver area. The successful implementation of “street-turn” strategy depends on the participation of each player. With a high level of information visibility, the proposed model can be employed as a decision support tool to identify “street-turn” opportunities and optimize empty container movements within the system.

description: The main aim of this paper is to study soliton surfaces immersed in Lie algebras associated with ordinary differential equations (ODE's) for elliptic functions. That is, given a linear spectral problem for such an ODE in matrix Lax representation, we search for the most general solution of the wave function which satisfies the linear spectral problem. These solutions allow for the explicit construction of soliton surfaces by the Fokas-Gel'fand formula for immersion, as formulated in (Grundland and Post 2011) which is based on the formalism of generalized vector fields and their prolongation structures. The problem has been reduced to examining three types of symmetries, namely, a conformal symmetry in the spectral parameter (known as the Sym-Tafel formula), gauge transformations of the wave function and generalized symmetries of the associated integrable ODE. The paper contains a detailed explanation of the immersion theory of surfaces in Lie algebras in connection with ODE's as well as an exposition of the main tools used to study their geometric characteristics. Several examples of the Jacobian and P-Weierstrass elliptic functions are included as illustrations of the theoretical results.

description: The interface between polar LaAlO3 and non-polar SrTiO3 exhibits a remarkable variety of electronic behavior associated with the formation of an interfacial quasi-two-dimensional electron gas (q-2DEG). By "sketching" patterns of charge on the top LaAlO3 surface, the LaAlO3/SrTiO3 interface conductance can be controlled with near-atomic spatial resolution. Using this technique, a sketch-based oxide nanotransistor (SketchFET) was demonstrated with a minimum feature size of just two nanometers. Here we report direct measurements of the potential barriers and electronic coupling between nanowire segments within a SketchFET device. Near room temperature, switching is governed by thermally activated field emission from the nanowire gate. Below T=150 K, a crossover to quantum field emission is observed that is sensitive to structural phase transitions in the SrTiO3 layer. This direct measurement of the source-drain and gate-drain energy barriers is crucial for the development of room-temperature logic and memory elements and low-temperature quantum devices.

description: We present the formal derivation of a new unidirectional model for unsteady mixed flows in non uniform closed water pipe. In the case of free surface incompressible flows, the \FS-model is formally obtained, using formal asymptotic analysis, which is an extension to more classical shallow water models. In the same way, when the pipe is full, we propose the \Pres-model, which describes the evolution of a compressible inviscid flow, close to gas dynamics equations in a nozzle. In order to cope the transition between a free surface state and a pressured (i.e. compressible) state, we propose a mixed model, the \PFS-model, taking into account changes of section and slope variation.

description: [Reflections on the problem of the overeveniences in the contract being executed during the covid-19 health emergency] According to the main regulatory provisions of supranational and national legislation on public procurement and by virtue of the principles laid down by the case law on events occurring during the execution of the contract for the award of services and supplies (even of modest economic value), there seems to be no doubt about the possibility of extending these events in the context of the current health emergency from Covid-19. This circumstance would legitimize the Public Administration to enter into the necessary negotiations with the contractor in order to agree on the modification of certain contractual clauses that cannot be implemented under normal conditions due to the health emergency.

description: The aim of this work is to model the jets produced by conical wire arrays on the MAGPIE generator, and to design and test new setups to strengthen the link between laboratory and astrophysical jets. We performed the modelling with direct three-dimensional magneto-hydro-dynamic numerical simulations using the code GORGON. We applied our code to the typical MAGPIE setup and we successfully reproduced the experiments. We found that a minimum resolution of approximately 100 is required to retrieve the unstable character of the jet. We investigated the effect of changing the number of wires and found that arrays with less wires produce more unstable jets, and that this effect has magnetic origin. Finally, we studied the behaviour of the conical array together with a conical shield on top of it to reduce the presence of unwanted low density plasma flows. The resulting jet is shorter and less dense.

Identification of Novel Inhibitors of the Amino Acid Transporter B0AT1 (SLC6A19), a Potential Target to Induce Protein Restriction and to Treat Type 2 Diabetes

description: Apical broad-spectrum neutral (0) amino acid transporter B0AT1 (encoded by the SLC6A19 gene) is mainly expressed in small intestine and kidney, mediating the transport of all neutral amino acids in a Na+-dependent manner. Its ancillary proteins, carboxypeptidase angiotensin-converting enzyme 2 (ACE2) and the homolog collectrin (TMEM27, transmembrane protein 27), are critical for the surface expression and catalytic transport function in small intestine and kidney, respectively. Slc6a19 nullizygous mice have improved insulin sensitivity and show reduced weight gain on a HFD (high fat diet) compared to wild-type mice. Moreover, reduced insulin secretion could protect β-cells from endoplasmic reticulum (ER) stress and long-term failure in insulin secretion. Hence, pharmacological inhibition of B0AT1 using chemical compounds could lead to new drugs to treat type 2 diabetes (T2DM) and its related metabolic disorders. A CHO (Chinese Hamster Ovary) - based cell line was generated, stably expressing B0AT1 and collectrin with the aid of a Flp-In™ transfection system. Using this cell line, a high-throughput screening (HTS) assay was developed, which uses a fluorescent dye to detect depolarisation of the cell membrane during amino acid uptake via B0AT1. A radio-labelled substrate uptake assay was used to determine the potency (IC50) and mechanism (competitive or non-competitive) of inhibition, as well as the specificity of B0AT1 inhibitors. Potential novel inhibitors were derived from three sources, first commercially available substrate analogues, second medium-scale virtual screening, and third high-throughput screening of chemical libraries. Selected inhibitors were further tested in in-vitro (Xenopus laevis oocytes), ex-vivo (mouse small intestine) and in-vivo (C57BL/6NCrl wild-type mice) systems. I characterised a series of novel inhibitors of the B0AT1 transporter in more detail. Benztropine (NSC63912) was identified as a competitive inhibitor showing an IC50 of 44±9µM; whereas 2-benzyl-1-(3-phenylpropyl)piperidine (NSC22789) was identified as a non-competitive inhibitor with an IC50 of 90±21µM. These two compounds were selective with regard to related transporters (system L, ASCT2), and they blocked substrate (leucine) uptake in both Xenopus oocytes overexpressing B0AT1 and collectrin, and inverted mouse small intestine. Two more potent B0AT1 inhibitors with IC50 below 10µM were further identified from the HTS of a small molecule compound library. The tools established in this study can be widely used to identify new transport inhibitors. Using these tools we were able to identify compounds that can be used to study epithelial transporters or be developed further through medicinal chemistry.
Removal of zero-point drift from AB data and the statistical cost

description: Often the result of a scientific experiment is given by the difference of measurements in two configurations, denoted by A and B. Since the measurements are not obtained simultaneously, drift of the zero-point can bias the result. In practice measurement patterns are used to minimize this bias. The time sequence AB followed by BA, for example, would cancel a linear drift in the average difference A-B. We propose taking data with an alternating series ABAB.., and removing drift with a post-hoc analysis. We present an analysis method that removes bias from the result for drift up to polynomial order p. A statistical cost function c(N) is introduced to compare the uncertainty in the end result with that from using a raw data average. For a data set size N>30 the statistical cost is negligible. For N<30 the cost is plotted as a function of N and filter order p and the trade off between the size of the data set and p is discussed.

description: For over two decades, Pacific island states have been active participants in multilateral climate change negotiations. Yet little is known about how these small states perform inside multi party negotiations, far less their contribution in building and reaching a consensus. This thesis investigates the behaviour of fourteen Pacific island states, by examining their negotiators and their activities in international, regional and global negotiation processes. It uses global talanoa to trace their work in the making of the UN climate change Paris Agreement in 2015, by detailing the complexity of the structures, issues, actors, politics and decision making processes inside various multilateral forums: the Ad Hoc Durban Platform (ADP), Pacific Islands Development Forum (PIDF), Pacific Islands Forum (PIF), and the twenty first Conference of the Parties (COP21). Beyond the structural conditions (rules, formula, procedures, the Chair) and incremental stages of negotiations, this thesis finds there is a small core group of individuals in each forum that condition and precipitate the building and reaching multilateral climate change consensus. Underpinning the work of the core group of Pacific leaders and technical negotiators is their resilience and their success in conducting cordial exchange of ideas, interests and building trust and respectful relationships in the coalitions they belong to, and amongst other parties in the negotiations.

Essays on firms' accounting quality
Creators: name: Yun, Ke
Publisher: name: University of British Columbia
Year: 2015

description: This dissertation consists of two essays that present new evidence on the determinants and consequences of accounting quality. The first essay examines the consequences of earnings quality on a firm’s use of trade credit. I use earnings smoothness, asymmetric timeliness of earnings (conservatism), and earnings management to proxy for earnings quality. Consistent with high accounting quality reducing information asymmetry between firms and stakeholders, I hypothesize and find that firms with higher accounting quality are able to obtain more trade credit from their suppliers. Using a customer-supplier paired subsample, I show that the results are robust after controlling for suppliers’ characteristics. Moreover, using the 2007–2008 financial crisis as an exogenous shock to credit supply, I show that the positive relation between trade credit and accounting quality is more pronounced during a period of credit tightening. Furthermore, I find that the characteristics of transacted products also impact the relation—the association is stronger when companies purchase services or differentiated goods. Finally, I show that the positive association is concentrated in small firms and firms without credit ratings on senior debt. Overall, the evidence suggests that high earnings quality facilitates firms’ access to trade credit from suppliers. The second essay documents the effect of stock underpricing on firms’ financial reporting quality. I use mutual fund fire sales to identify relatively underpriced stocks and use performance-matched discretionary accruals to proxy for earnings management. Using difference-in-differences tests, I find that firms subjected to mutual fund fire sales increase their level of earnings management relative to unaffected firms. I also show that the effect is greater for firms experiencing more severe underpricing, firms with higher information asymmetry, and lower stock liquidity. In addition, earnings management is more pronounced in financially constrained firms. Finally, I examine whether earnings management helps stock price recovery, but find no evidence to support this hypothesis. In sum, the second essay finds that stock underpricing adversely affects firms’ financial reporting quality, an indirect effect of the stock market that has been previously overlooked.

description: [Driverless car or driverless law: which direction will the law take to avoid “systematic accidents”?] The article, written jointly, investigates the civil liability profile of self-driving cars, focusing, in particular, on the different degrees of automation (from level 0 to level 5). The hypotheses of responsibility ascribed to this phenomenon are criticized, in some ways, without failing to share some observations proposed in this regard by the doctrine in recent months. The principles of precaution, responsibility and protection of life in automated choices represent the “hard core” of the work. Finally, it is argued that it is possible to start thinking of a statute of responsibility for driverless cars, based on respect for constitutional principles.

description: Piezoresponse force microscopy (PFM) was used to investigate the ferroelectric properties of sol-gel derived LiNbO$_3$ nanoparticles. To determine the degree of ferroelectricity we took large-area images and performed statistical image-analysis. The ferroelectric behavior of single nanoparticles was verified by poling experiments using the PFM tip. Finally we carried out simultaneous measurements of the in-plane and the out-of-plane piezoresponse of the nanoparticles, followed by measurements of the same area after rotation of the sample by 90$^{\circ}$ and 180$^{\circ}$. Such measurements basically allow to determine the direction of polarization of every single particle.
Investigating the role of cause-and-effect simulation design in persuading online consumers to go green

description: This study examines the role of technology in motivating online consumers to purchase green products. The cause-and-effect simulation proposed by Fogg (2002) and the construal-level theory (CLT, Liberman and Trope 1998) are employed to develop two website designs: 1) the low-level and 2) the high-level cause-and-effect simulation. Both simulation designs show the relationship between consumers’ decision-making on the product attributes, the cause, and its impact on resources (e.g., energy) the product consumes, the effect. A recommendation agent (RA) is used to reflect the cause part of both designs. The main difference between the two designs is the effect part developed based on CLT. Specifically, the low-level simulation presents a more concrete, short-term effect, the utility cost per load, and the high-level simulation provides a more abstract, long-term effect, the 10-year utility cost. We compare these two designs against two control conditions—1) the no simulation which does not provide the RA and the utility cost and 2) the partial simulation which has only the RA. An online experiment with 79 participants was conducted to evaluate the effectiveness of the simulation design on the green selection. Specifically, we assess whether the simulation design could persuade people to pay more for green products. The experimental results show both low-level and high-level simulations successfully motivate participants to choose greener products than the no simulation and the partial simulation. Moreover, the results suggest both full designs persuade participants to go green by enhancing the desirability consideration associated with the outcome resulting from the green purchase. This consideration was found to influence self-efficacy which leads to greener choices. Self-efficacy was also found to have a greater impact on the green product selection than participants’ attitudes. This is evident by the fact that participants generally have a pre-existing positive intention to buy green products. Thus, the role of the cause-and-effect simulation design is not so much to change people’s attitudes, but rather to reinforce those positive attitudes and thus help participants to abide by their good intentions. In other words, it helps increase self-efficacy that would be the key to promote the green purchase.

Fermi Large Area Telescope observations of Local Group galaxies: Detection of M31 and search for M33

description: Cosmic rays (CRs) can be studied through the galaxy-wide gamma-ray emission that they generate when propagating in the interstellar medium. The comparison of the diffuse signals from different systems may inform us about the key parameters in CR acceleration and transport. We aim to determine and compare the properties of the CR-induced gamma-ray emission of several Local Group galaxies. We use 2 years of nearly continuous sky-survey observations obtained with the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope to search for gamma-ray emission from M31 and M33. We compare the results with those for the Large Magellanic Cloud, the Small Magellanic Cloud, the Milky Way, and the starburst galaxies M82 and NGC253. We detect a gamma-ray signal at 5sigma significance in the energy range 200 MeV-20 GeV that is consistent with originating from M31. The integral photon flux above 100MeV amounts to 9.1 +/- 1.9 (stat) +/- 1.0 (sys) x10e-9 ph/cm2/s. We find no evidence for emission from M33 and derive an upper limit on the photon flux >100MeV of 5.1 x10e-9 ph/cm2/s (2sigma). Comparing these results to the properties of other Local Group galaxies, we find indications for a correlation between star formation rate and gamma-ray luminosity that also holds for the starburst galaxies. The gamma-ray luminosity of M31 is about half that of the Milky Way, which implies that the ratio between the average CR densities in M31 and the Milky Way amounts to 0.35 +/- 0.25. The observed correlation between gamma-ray luminosity and star formation rate suggests that the flux of M33 is not far below the current upper limit from the LAT observations.

Limiting phase trajectories and the origin of energy localization in nonlinear oscillatory chains

description: We demonstrate that the modulation instability of the zone boundary mode in a finite (periodic) Fermi-Pasta-Ulam chain is the necessary but not sufficient condition for the efficient energy transfer by localized excitations. This transfer results from the exclusion of complete energy exchange between spatially different parts of the chain, and the excitation level corresponding to that turns out to be twice more than threshold of zone boundary mode's instability. To obtain this result one needs in far going extension of the beating concept to a wide class of finite oscillatory chains. In turn, such an extension leads to description of energy exchange and transition to energy localization and transfer in terms of 'effective particles' and Limiting Phase Trajectories. The 'effective particles' appear naturally when the frequency spectrum crowding ensures the resonance interaction between zone boundary and two nearby nonlinear normal modes, but there are no additional resonances. We show that the Limiting Phase Trajectories corresponding to the most intensive energy exchange between 'effective particles' can be considered as an alternative to Nonlinear Normal Modes, which describe the stationary process.

description: We investigate X-ray emission properties of the peculiar X-ray source Theta2 Ori A in the Orion trapezium region using more than 500 ksec of HETGS spectral data in the quiescent state. The amount of exposure provides tight constraints on several important diagnostics involving O, Ne, Mg, and Si line flux ratios from He-like ion triplets, resonance line ratios of the H- and He-like lines and line widths. Accounting for the influence of the strong UV radiation field of the O9.7V star we can now place the He-like line origin well within two stellar radii of the O-star's surface. The lines are resolved with average line widths of 341+-38 km/s confirming a line origin relatively close to the stellar surface. In the framework of standard wind models this implies a rather weak, low opacity wind restricting wind shocks to temperatures not much larger than 2x10^6 K. The emission measure distribution of the X-ray spectrum, as reported previously, includes very high temperature components which are not easily explained in this framework. The X-ray properties are also not consistent with coronal emissions from an unseen low-mass companion nor with typical signatures from colliding wind interactions. The properties are more consistent with X-ray signatures observed in the massive Trapezium star Theta1 Ori C which has recently been successfully modeled with a magnetically confined wind model.
