description: We construct a class of Hamiltonians that describe the photodetection process from beginning to end. Our Hamiltonians describe the creation of a photon, how the photon travels to an absorber (such as a molecule), how the molecule absorbs the photon, and how the molecule after irreversibly changing its configuration triggers an amplification process---at a wavelength that may be very different from the photon's wavelength---thus producing a macroscopic signal. We use a simple prototype Hamiltonian to describe the single-photon detection process analytically in the Heisenberg picture, which neatly separates desirable from undesirable effects. Extensions to more complicated Hamiltonians are pointed out.

description: We study a new mechanism of wave/electron scattering in multi-mode surface-corrugated waveguides/wires. This mechanism is due to specific square-gradient terms in an effective Hamiltonian describing the surface scattering, that were neglected in all previous studies. With a careful analysis of the role of roughness slopes in a surface profile, we show that these terms strongly contribute to the expression for the inverse attenuation length (mean free path), provided the correlation length of corrugations is relatively small. The analytical results are illustrated by numerical data.

description: Controlling and detecting thermal radiation is of vital importance for varied applications ranging from energy conversion systems and nanoscale information processing devices to infrared imaging, spectroscopy and sensing. We review the field of high temperature thermal photonics which aims to control the spectrum, polarization, tunability, switchability and directionality of heat radiation from engineered materials in extreme environments. We summarize the candidate materials which are being pursued by the community that have simultaneous polaritonic/plasmonic properties as well as high temperature stability. We also provide a detailed discussion of the common photonic platforms including meta-gratings, photonic crystals, and metamaterials used for thermal emission engineering. We review broad applications including thermophotovoltaics, high temperature radiative cooling, thermal radiation sources, and noisy nanoscale thermal devices. By providing an overview of the recent achievements in this field, we hope this review can accelerate progress to overcome major outstanding problems in modern thermal engineering.

description: We propose an improved density integration methodology for Background Oriented Schlieren (BOS) measurements that overcomes the noise sensitivity of the commonly used Poisson solver. The method employs a weighted least-squares (WLS) optimization of the 2D integration of the density gradient field by solving an over-determined system of equations. Weights are assigned to the grid points based on density gradient uncertainties to ensure that a less reliable measurement point has less effect on the integration procedure. Synthetic image analysis with a Gaussian density field shows that WLS constrains the propagation of random error and reduces it by 80% in comparison to Poisson for the highest noise level. Using WLS with experimental BOS measurements of flow induced by a spark plasma discharge show a 30% reduction in density uncertainty in comparison to Poisson, thereby increasing the overall precision of the BOS density measurements.

description: Epitaxial silicon p-n junctions are attracting attention for their potential applications in thermal energy conversion technologies due to their manufacturing efficiency and scalability. This paper explores the optimization of epitaxial silicon p-n junctions to improve thermal energy conversion efficiency, focusing on material properties, device structure, and fabrication techniques. We analyze different doping profiles, the role of interface quality, and thermal transport mechanisms in silicon-based p-n junctions. In addition, this study discusses challenges and opportunities in improving thermoelectric efficiency through design and manufacturing process improvements. The findings show that optimization of junction interfaces and careful control of doping concentrations can significantly improve energy conversion efficiency in silicon-based thermoelectric devices.

description: There is a growing policy pressure to reduce water use in agriculture when this generates sufficiently large environmental benefits and increases the well-being of other water users. Several analysis investigate farmers’ response to water policy by means of mathematical programming models including Positive Mathematical Programming (PMP). The originals PMP methods refer only to activities observed in the reference period. However, under the pressure of new water policies, farmers can adjust not only their cropping patterns but also the irrigation techniques they use. In particular, they could introduce water deficit irrigation crop techniques that were not profitable in past conditions. This paper proposes an extension of the Röhm and Dabbert approach (2003) in order to include deficit irrigation crop techniques not observed in the reference period into a PMP model. These alternative techniques are identified by means of a crop growth model developed by FAO. The proposed methodology is applied to a Mediterranean area performing two sets of simulations considering : the increase of water cost and the reduction of water availability. The results shows that, when water availability decreases, not considering adjustments in irrigation techniques is likely to underestimate the extent of farmers’ response to the new policy scenarios. In facts, introducing deficit irrigation techniques can alleviate the negative impact of decreasing water availability on farm economic results by using more efficiently this resource. However, this is not the case for the considered water cost increases.

description: We experimentally investigate longitudinal and transverse second-harmonic voltage response to ac electrical current for a magnetic Weyl semimetal Co$_3$Sn$_2$S$_2$. In contrast to the previously observed Berry-curvature induced non-linear Hall effect for non-magnetic Weyl and Dirac semimetals, the second-harmonic transverse voltage demonstrates sophisticated interplay of different effects for Co$_3$Sn$_2$S$_2$. In high magnetic fields, it is of Seebeck-like square-B law, while the low-field behavior is found to be linear and sensitive to the direction of sample magnetization. The latter can be expected both for the non-linear Hall effect and for the surface state contribution to the Seebeck effect in Weyl semimetals. Thus, thermoelectric effects are significant in Co$_3$Sn$_2$S$_2$, unlike non-magnetic Weyl and Dirac materials.

In particular, we have shown that just having atoms of different size leads to a remarkable stabilization of polytetrahedral structures, including both polyicosahedral clusters and at larger sizes structures with disclination lines.

description: The cause of changes in the wage differential between skilled and unskilled labor has been an important subject of debate for several decades. International trade and productivity growth are two main causes that have been suggested from large country studies. Recent research proposes that education is another influence. All three causes have been significantly associated with Taiwan’s economic development. This paper attempts to contribute to the literature by investigating the wage differential in Taiwan, a small open economy. A Dynamic Intertemporal General Equilibrium (DIGE) model is used to perform theoretical simulation. An Error Correction Model (ECM) incorporating both short- and long-run effects is employed to accomplish the empirical examination. That education and international trade are important causes of changes in the wage differential is substantiated by Taiwanese data. Productivity growth has a significant influence on the wage differential in the short run but not in the long run.

description: Ab initio calculations are utilized as an input to develop a simple model of polarization in epitaxial short-period CaTiO3/SrTiO3/BaTiO3 superlattices grown on a SrTiO3 substrate. The model is then combined with a genetic algorithm technique to optimize the arrangement of individual CaTiO3, SrTiO3 and BaTiO3 layers in a superlattice, predicting structures with the highest possible polarization and a low in-plane lattice constant mismatch with the substrate. This modelling procedure can be applied to a wide range of layered perovskite-oxide nanostructures providing guidance for experimental development of nanoelectromechanical devices with substantially improved polar properties.

Riccati-parameter solutions of nonlinear second-order ODEs

description: It has been proven by Rosu and Cornejo-Perez in 2005 that for some nonlinear second-order ODEs it is a very simple task to find one particular solution once the nonlinear equation is factorized with the use of two first-order differential operators. Here, it is shown that an interesting class of parametric solutions is easy to obtain if the proposed factorization has a particular form, which happily turns out to be the case in many problems of physical interest. The method that we exemplify with a few explicitly solved cases consists in using the general solution of the Riccati equation, which contributes with one parameter to this class of parametric solutions. For these nonlinear cases, the Riccati parameter serves as a `growth' parameter from the trivial null solution up to the particular solution found through the factorization procedure

description: The notion of graph filters can be used to define generative models for graph data. In fact, the data obtained from many examples of network dynamics may be viewed as the output of a graph filter. With this interpretation, classical signal processing tools such as frequency analysis have been successfully applied with analogous interpretation to graph data, generating new insights for data science. What follows is a user guide on a specific class of graph data, where the generating graph filters are low-pass, i.e., the filter attenuates contents in the higher graph frequencies while retaining contents in the lower frequencies. Our choice is motivated by the prevalence of low-pass models in application domains such as social networks, financial markets, and power systems. We illustrate how to leverage properties of low-pass graph filters to learn the graph topology or identify its community structure; efficiently represent graph data through sampling, recover missing measurements, and de-noise graph data; the low-pass property is also used as the baseline to detect anomalies.

description: Health is an increasingly important topic in the food market. The regulation (EC) No 1924/2006 on nutrition and health claims is meant to facilitate healthy food choices of consumers. However, research studies about claim perception and choice behaviour are scarce in Europe up to this point, especially those focusing on revealed preferences or a close-to-realistic study design. This contribution reports findings of realistically designed choice-tests accompanied by video-observation and followed by a face-to-face questionnaire. Logistic regression analysis was applied in order to determine the influencing factors on purchase behaviour of food products with claims. Perception of relative healthiness of the product with a claim, credibility of the claim and extent of information acquisition were found to influence choice positively, while claim format and product category were of no importance.

description: Consumers are facing increasing information on health and nutritional aspects of foods, an important source of which is that presented in food packages. Prior research has identified that this information is positively valued, but the effect of multiple information items simultaneously is not so well understood. A choice experiment has been conducted to identify the effect of multiple health and nutrition information sources in two products which represent both a healthy and less-healthy food (pork Frankfurt sausages and plain yoghurt respectively). Results show that although highly heterogeneous, preferences seem to positively value individual information items and negatively value the presence of more than one item, specially if the item is a health claim. Premiums consumers are willing to pay represent a significant percentage of retail price, specially for the less healthy food product which also faces lower retails prices.

Results indicate that food prices in Iran have a long-run and short-run equilibrium granger causality relationship with money supply. More specifically, monetary policy reforms are shown to have a significant impact on food prices and domestic agricultural production. These policies influence consumption patterns and have serious implications for poverty reduction, food security issues, and agricultural growth in Iran.

description: With the increasing growth of cyber-attack incidences, it is important to develop innovative and effective techniques to assess and defend networked systems against cyber attacks. One of the well-known techniques for this is performing penetration testing which is carried by a group of security professionals (i.e, red team). Penetration testing is also known to be effective to find existing and new vulnerabilities, however, the quality of security assessment can be depending on the quality of the red team members and their time and devotion to the penetration testing. In this paper, we propose a novel automation framework for cyber-attacks generation named `HARMer' to address the challenges with respect to manual attack execution by the red team. Our novel proposed framework, design, and implementation is based on a scalable graphical security model called Hierarchical Attack Representation Model (HARM). (1) We propose the requirements and the key phases for the automation framework. (2) We propose security metrics-based attack planning strategies along with their algorithms. (3) We conduct experiments in a real enterprise network and Amazon Web Services. The results show how the different phases of the framework interact to model the attackers' operations. This framework will allow security administrators to automatically assess the impact of various threats and attacks in an automated manner.

description: We report experiments on electron interferometer devices in the quantum Hall regime, where edge channels circle a 2D electron island. The main confinement is produced by etch trenches, into which front gate metal is deposited. We find a linear dependence of the Aharonov-Bohm period on gate voltage for electrons (integer filling f=1) and for Laughlin quasiparticles (fractional 2/5 embedded in 1/3). The capacitance of a large 2D electron island with respect to the front gates is approximately proportional to the island radius. Comparing the experimental data for the integer and the fractional fillings and for two samples, we find the magnetic field period and its slope scale with the radius of the Aharonov-Bohm orbit. Analysis of the directly measured integer and fractional slope data allows to determine the interferometer area in the fractional regime, and thus the Laughlin quasiparticle flux period of 5h/e, within the experimental accuracy.

A journey in metaxis : been, being, becoming, imag(in)ing drama facilitation
Creators: name: Linds, Warren
Publisher: name: University of British Columbia
Year: 2009

description: A journey in metaxis explores the facilitation of drama workshops using an adaptation of Theatre of the Oppressed, a participatory drama process used with high school students, teachers and others in the community. New possibilities of engagement open up as knowing emerges through a variety o f forms of dramatic action which are simultaneously the medium, subject and re-presentation of research. As a theatre pedagogue I explore how knowing and meaning emerge through theatre and in the interplay between my life and my work. Writing, then reading, narratives of my practice engages me in a conversation that helps me draw attention to my practice. Diverse roles and points of view of the drama facilitator begin to become apparent as these narratives speak through a spiralling process of shared experiences. Commentaries on these experiences lead to discussions of the implications of this inquiry for other forms of reflective leadership practice in drama and in education. Particular attention is placed on the role of the body and mind (bodymind) of facilitator and participants as they journey into an increasing awareness of senses, histories, the landscapes worked in, and the relationships that intertwine through the constant ebb and flow of the drama workshop. Using a framework that parallels the drama workshop I facilitate, I play with forms of texts, languages and styles to enter into the text(ure) of the worlds of facilitation so that we may come face to face with kinaesthetic and discursive experiences remembered and reconsidered. Writing my body into this exploration enables me to become mindfully aware of, and extends and transforms, my practice. I re-awaken the memory of my senses and re-connect with them in the moments of "performing" my teaching. Such poetic and expressive writing enables an evocation of the world of drama. Writing from and through a sensing body means that reflection on practice becomes not merely reporting experiences, but also celebrating and expressing the multi-vocal, multi-layered events that develop drama facilitation skills. Writing, then reading, about this process of coming to know my identity-in-process as a drama facilitator enables the interpretation, interrogation and transformation of how one becomes facilitator, "making the way as we go," (re)writing/performing our presence.

description: We address two finite size effects in perpendicular transport through magnetic multilayers. When the magnetic layer thickness in spin valves becomes of the order or smaller than the spin-flip diffusion length, structural asymmetries affect the transport properties. A magnetic layer with thickness approaching the magnetic coherence length becomes transparent for spin currents polarized perpendicular to the magnetization. We use the generalized magnetoelectronic circuit theory to investigate both effects on the angular magnetoresistance (aMR) and spin transfer torque. We analyze recent aMR experiments to determine the spin-flip diffusion length in the ferromagnet as well as the interface spin-mixing conductance and propose a method to measure the ferromagnetic coherence length.

description: The purpose of this paper is to analyze the world rice market through a Structure-Conduct-Performance (SCP) framework utilizing annual data from 1970 to 2007. Since World War Two, the world rice market has been very unstable, with rice prices experiencing volatile swings in both rice price and rice availability. Therefore, a SCP framework can provide crucial insight into the world rice market for policy makers. Also, this paper describes the effects of total production, export rice price, and real exchange rate for exporting countries on total export volume from an export supply model standpoint. On the basis of these results, it is evident that market power exists in the international rice market with respect to supply elasticity and an exporting country’s currency exchange rate greatly determines that country’s competitiveness as a net rice exporter relative to other rice producers.

Here we calculate all the symmetries of these models and their submodels by the prolongation method. We find that for some models, like the Baby Skyrme model, the submodels have additional symmetries, whereas for others, like the Faddeev--Niemi model, they do not.

description: Owing to the fundamental importance and potential applications, a lot of theoretical and experimental work is ongoing to control the light-matter coupling. Many significant quantum effects can be observed in stronger coupling regimes which give a better efficiency and control over the system. This thesis presents a multi-level atom in a non-equilibrium cavity quantum electrodynamics (QED) system considering dipole-dipole interactions in different coupling regimes. The influence of coherent and incoherent pumping are included to study the quantum coherence phenomena. The proposed model can be applied to QED chemistry, circuit QED, microcavities consisting of organic molecules, and quantum information processing.

description: This paper is aimed to investigate droplet formation mechanism of liquid/gas flow inside the T-junction microchannel. Various droplet formation regimes like squeezing, dripping and jetting regimes in low capillary number flows are investigated using the VOF model refined with smoothing operation to reduce spurious currents at the micro-scale. Effect of velocity field on droplet formation is studied. The results show that in squeezing regime, the effect of pressure build-up is more as compared to shear stress at gas/liquid interface. In dripping, shear force dominates over pressure; this is possible because of the small size of droplets compared to the channel width. In the end, the effect of capillary number on droplet characteristics such as slug length, the gap between slugs, the frequency of bubble formation and interfacial area is also investigated. It has been observed that microreactors should be operated at the low capillary number for efficient mass transfer.

description: This paper aims to (1) analyze the relationship between rice exports and economic growth for the world’s top four exporting countries (Thailand, Vietnam, India, and the U.S) and (2) seek to determine to what extent market power affects a country’s economic growth. The main objective of this paper is to determine to what extent economic growth impacts a country’s rice exports as well as to what extent Foreign Direct Investment (FDI) impacts a country’s ability to export rice. This analysis also examines the impact of market power on economic growth. On the basis of these results, we examine the existence of market power in the international rice market with respect to rice supply, and moreover, propose that there is a bi-directional causality between the international rice trade and economic growth for major rice exporting countries.

description: This analysis presents the determination of an import demand function for the world rice market using annual data from 1994 to 2007. In the specification and analysis of a world rice market import demand function, Ordinary Least Square (OLS), Instrumental Variables (IV) with Generalized Method of Moments (GMM), and Seemingly Unrelated Regression (SUR) methods have been used. Social welfare effects have been obtained using consumer surplus and compensated variation for the top four rice importing countries (Indonesia, Philippines, Nigeria, and Saudi Arabia). Empirical results suggest that economic growth, Foreign Direct Investment (FDI), and importing countries’ population positively affect national income, thus, positively affecting rice consumption. Oil price has a strong effect on the domestic rice prices in importing countries. This paper also estimates the social effects arising from increased rice export prices and examines how consumer surplus is affected in major rice importing countries.
Recent progress in first-principles studies of magnetoelectric multiferroics

description: Materials that combine magnetic and ferroelectric properties have generated increasing interest over the last few years, due to both their diverse properties and their potential utility in new types of magnetoelectric device applications. In this review we discuss recent progress in the study of such magnetoelectric multiferroics which has been achieved using computational first-principles methods based on density functional theory. In particular, we show how first-principles methods have been successfully used to explain various properties of multiferroic materials and to predict novel effects and new systems that exhibit multiferroic properties.

description: The paper establishes an equivalence between pure point diffraction and certain types of model sets, called inter model sets, in the context of substitution point sets and substitution tilings. The key ingredients are a new type of coincidence condition in substitution point sets, which we call algebraic coincidence, and the use of a recent characterization of model sets through dynamical systems associated with the point sets or tilings.

Modeling the broadest spectral band of the Crab nebula and constraining the ions acceleration efficiency

description: Although it is widely accepted that the electromagnetic spectrum from radio to very-high-energy $γ$-rays of pulsar wind nebulae (PWNe) originates from leptons, there is still an open question that protons (or more generally, ions) may exist in pulsar wind and are further accelerated in PWN. The broadband spectrum of the prototype PWN Crab, extended recently by the detection of the Tibet AS$γ$ and HAWC experiments above 100 TeV, may be helpful in constraining the acceleration efficiency of ions. Here, we model the broadest energy spectrum of Crab and find that the broadband spectrum can be explained by the one-zone leptonic model in which the electrons/positrons produce the emission from radio to soft $γ$-rays via the synchrotron process, and simultaneously generate the GeV-TeV $γ$-rays through inverse Compton scattering including the synchrotron self-Compton process. In the framework of this leptonic model, the fraction of energy converted into the energetic protons is constrained to be below $0.5\ (n_{\rm t}/10\ {\rm cm}^{-3})^{-1}$ per cent, where $n_{\rm t}$ is the target gas density in the Crab. However, this fraction can be up to $7\ (n_{\rm t}/10\ {\rm cm}^{-3})^{-1}$ per cent if only the $γ$-rays are used.
