description: We calculate the AC conductance and the finite-frequency non-symmetrized noise in interacting quantum wires and single-wall carbon nanotubes in the presence of an impurity. We observe a strong asymmetry in the frequency spectrum of the non-symmetrized excess noise, even in the presence of the metallic leads. We find that this asymmetry is proportional to the differential excess AC conductance of the system, defined as the difference between the AC differential conductances at finite and zero voltage, and thus disappears for a linear system. In the quantum regime, for temperatures much smaller than the frequency and the applied voltage, we find that the emission noise is exactly equal to the impurity partition noise. For the case of a weak impurity we expand our results for the AC conductance and the noise perturbatively. In particular, if the impurity is located in the middle of the wire or at one of the contacts, our calculations show that the noise exhibits oscillations with respect to frequency, whose period is directly related to the value of the interaction parameter $g$.

description: In the spirit of studying the information paradox as a scattering problem, we pose and answer the following questions: i) What is the scattering amplitude for $N$ particles to emerge from a large black hole when two energetic particles are thrown into it? ii) How long would we have to wait to recover the information sent in? The answer to the second question has long been expected to be Page time, a quantity associated with the lifetime of the black hole. We answer the first by evaluating an infinite number of `ladder of ladders' Feynman diagrams to all orders in $M_{Pl}/M_{BH}$. Such processes can generically be calculated in effective field theory in the black hole eikonal phase where scattering energies satisfy $E M_{BH} \gg M^{2}_{Pl}$. Importantly, interactions are mediated by a fluctuating metric; a fixed geometry is insufficient to capture these effects. We find that the characteristic time spent by the particles in the scattering region (the so-called Eisenbud-Wigner time delay) is indeed Page time, confirming the long-standing expectation. This implies that the entropy of radiation continues to increase, after the particles are thrown in, until after Page time, when information begins to re-emerge.

description: The entanglement in one-dimensional random XY spin systems where the impurities of exchange couplings and the external magnetic fields are considered as random variables is investigated by solving the different spin-spin correlation functions and the average magnetization per spin. The entanglement dynamics near particular locations of the system is also studied when the exchange couplings (or the external magnetic fields) satisfy three different distributions(the Gaussian distribution, double-Gaussian distribution, and bimodal distribution). We find that the entanglement can be controlled by varying the strength of external magnetic field and the different distributions of impurities. Moreover, the entanglement of some nearest-neighboring qubits can be increased for certain parameter values of the three different distributions.

description: Natural and human-made disasters have dramatically increased during the last decades. Given the strong relationship between first responders localization time and the final number of deaths, the modernization of search-and-rescue operations has become imperative. In this context, Unmanned Aerial Vehicles (UAVs)-based solutions are the most promising candidates to take up on the localization challenge by leveraging on emerging technologies such as: Artificial Intelligence (AI), Reconfigurable Intelligent Surfaces (RIS) and Orthogonal Time Frequency Space (OTFS) modulations. In this paper, we capitalize on such recently available techniques by shedding light on the main challenges and future opportunities to boost the localization performance of state-of-the-art techniques to give birth to unprecedentedly effective missing victims localization solutions.

description: Der Erwerb von Kompetenzen zum naturwissenschaftlichen Denken (scientific reasoning) wird in den nationalen Bildungsstandards gefordert. Damit naturwissenschaftliches Denken in den Unterrichtsalltag integriert wird, ist eine Implementierung in die rechtlich bindenden Lehrpläne erforderlich. Die styles of scientific reasoning (Experimentieren, Modellieren, Kategorisieren & Klassifizieren, deduktives, probabilistisches & historisch-evolutionäres Schlussfolgern) nach Kind und Osborne (2017) erlauben eine differenzierte Betrachtung des Konstrukts, indem sie auf einer prozeduralen und epistemischen Ebene verschiedene biologiespezifische Arbeits- und Denkweisen beschreiben. Mit der Analyse der Lehrpläne aller Bundesländer soll ein Überblick gewonnen werden, inwieweit verschiedene Aspekte der styles of scientific reasoning in den Lehrplänen implementiert sind. Die Analyse findet an den aktuell geltenden Biologie-Lehrplänen der Bundesländer für die Sekundarstufe II statt. Die Dokumente wurden auf Basis eines Kategoriensystems, das Kompetenzerwartungen zu den einzelnen styles enthält, kodiert. Über alle Lehrpläne hinweg ließen sich 20 Kompetenzerwartungen finden. Statt einer gleichmäßigen Berücksichtigung der styles zeigt sich eine Fokussierung auf die Arbeitsweise Experimentieren, dort auf vorwiegend prozedurale Subkategorien wie „Experimente durchführen“. Subkategorien aus dem style probabilistisches und historisch-evolutionäres Schlussfolgern finden sich selten wieder. Ein Zusammenhang zwischen der Anzahl der gefundenen Subkategorien und dem Erscheinungsjahr der Lehrpläne ist nicht erkennbar. Scientific reasoning ist hinsichtlich der styles demnach nur teilweise in den Lehrplänen repräsentiert. Explizit zu fördernde epistemische Aspekte treten genauso wie die Denkweisen probabilistisches und historisch-evolutionäres Schlussfolgern in den Lehrplänen selten auf.

description: To facilitate cost-effective and elastic computing benefits to the cloud users, the energy-efficient and secure allocation of virtual machines (VMs) plays a significant role at the data centre. The inefficient VM Placement (VMP) and sharing of common physical machines among multiple users leads to resource wastage, excessive power consumption, increased inter-communication cost and security breaches. To address the aforementioned challenges, a novel secure and multi-objective virtual machine placement (SM-VMP) framework is proposed with an efficient VM migration. The proposed framework ensures an energy-efficient distribution of physical resources among VMs that emphasizes secure and timely execution of user application by reducing inter-communication delay. The VMP is carried out by applying the proposed Whale Optimization Genetic Algorithm (WOGA), inspired by whale evolutionary optimization and non-dominated sorting based genetic algorithms. The performance evaluation for static and dynamic VMP and comparison with recent state-of-the-arts observed a notable reduction in shared servers, inter-communication cost, power consumption and execution time up to 28.81%, 25.7%, 35.9% and 82.21%, respectively and increased resource utilization up to 30.21%.

Cantus firmus chansons by Alexander Agricola
Creators: name: Kravinchuk, Daniel Peter
Publisher: name: University of British Columbia
Year: 2010

description: The secular works of Alexander Agricola have received little attention from musicologists, particularly those secular works which adopt a voice part from another composer's work. The thesis investigates not only the style of Agricola's cantus firmus chansons but compares that composer's cantus firmus techniques with those of his contemporaries. In addition, an inquiry is made into possible influence of the model (aside from the borrowed voice itself) on the non-cantus firmus parts of such settings. Selection is limited to four cantus firmus families, representing all but one of those families for which Agricola made more than one setting of the same cantus firmus. Allusions to aspects of a model's structure or melody (apart from the borrowed line) are comparatively minor in the settings examined here. They are apt to be small quotations, often of theiincipit, with conventional references to the musical structure of the model chanson. The stylistic features of Agricola revealed in these settings are similar to those found in his works in other genres. And while the cantus firmus techniques that this composer used resemble those of his contemporaries, two works by Agricola, a four-part Tout a par moy and a three-voice D'ung aultre amer, present a transitional stage from arrangements of a cantus prius factus (newly-composed voices unrelated to the borrowed part) to parody (incorporation of melodies and structure of the model). These two settings by Agricola progress beyond even the more forward-looking cantus firmus techniques found in chansons by Japart, Ghiselin/Verbonnet and Josquin.

description: We explore the codimension one strata in the degree-one cohomology jumping loci of a finitely generated group, through the prism of the multivariable Alexander polynomial. As an application, we give new criteria that must be satisfied by fundamental groups of smooth, quasi-projective complex varieties. These criteria establish precisely which fundamental groups of boundary manifolds of complex line arrangements are quasi-projective. We also give sharp upper bounds for the twisted Betti ranks of a group, in terms of multiplicities constructed from the Alexander polynomial. For Seifert links in homology 3-spheres, these bounds become equalities, and our formula shows explicitly how the Alexander polynomial determines all the characteristic varieties.

Mean-field dynamics of a two-mode Bose-Einstein condensate subject to noise and dissipation

description: We discuss the dynamics of an open two-mode Bose-Hubbard system subject to phase noise and particle dissipation. Starting from the full many-body dynamics described by a master equation the mean-field limit is derived resulting in an effective non-hermitian (discrete) Gross-Pitaevskii equation which has been introduced only phenomenologically up to now. The familiar mean-field phase space structure is substantially altered by the dissipation. Especially the character of the fixed points shows an abrupt transition from elliptic or hyperbolic to attractiv or repulsive, respectively. This reflects the metastable behaviour of the corresponding many-body system which surprisingly also leads to a significant increase of the purity of the condensate. A comparison of the mean-field approximation to simulations of the full master equation using the Monte Carlo wave function method shows an excellent agreement for wide parameter ranges.

description: The integration of advanced localization techniques in the upcoming next generation networks (B5G/6G) is becoming increasingly important for many use cases comprising contact tracing, natural disasters, terrorist attacks, etc. Therefore, emerging lightweight and passive technologies that allow accurately controlling the propagation environment, such as reconfigurable intelligent surfaces (RISs), may help to develop advance positioning solutions relying on channel statistics and beamforming. In this paper, we devise PAPIR, a practical localization system leveraging on RISs by designing a two-stage solution building upon prior statistical information on the target user equipment (UE) position. PAPIR aims at finely estimating the UE position by performing statistical beamforming, direction-of-arrival (DoA) and time-of-arrival (ToA) estimation on a given three-dimensional search space, which is iteratively updated by exploiting the likelihood of the UE position.

Slides for a Webinar on Arlington Microgrid V2G Demo Project Deployment, Integration Insights
The Arlington Microgrid (MG) was approved for co-funding by the WA State Clean Energy Fund in May 2017.  In February 2022, the Arlington MG was successfully commissioned and then accepted by Snohomish PUD (SnoPUD).  While Covid impacted the timeline from funding-approval to acceptance, there were abundant technical challenges in the design thru deployment that added to this timeline.  A major overall challenge that consumed significant engineering time and effort was integration across the various assets and the overall MG monitoring and control systems.  This was particularly true for the Vehicle-to-Grid (V2G) portion of the Arlington MG’s overall scope.  This would be expected given the very early stage of industry experience with V2G technology, vs the BESS and PV resources also connected to the MG. The Arlington demonstration is a great platform to evaluate what went right, and what needs further improvement to lower integration-related barriers to V2G’s broader industry adoption and use.
The webinar will start with a recap by SnoPUD of their Arlington Microgrid project, and specific integration challenges overcome to allow the V2G to participate as an active MG resource.   This will be followed by a recap of an analysis performed by PNNL that 1) evaluated the Arlington V2G specification against newer and pending Standards that weren’t present to support initial project design and 2) identification of the standards that will have to be coordinated across two industries for V2G to flourish, i.e. the IEEE and SAE.  The webinar will conclude with discussion on next steps from an industry perspective, e.g. what standards need further development to provide a prudent but receptive technical environment for V2G to evolve.

description: The unusual temperature behavior of the entropy of the antiferromagnetic (AFM) spin state in symmetric nuclear matter with the Gogny D1S interaction, being larger at low temperatures than the entropy of nonpolarized matter, is related to the dependence of the entropy on the effective masses of nucleons in a spin polarized state. The corresponding conditions for comparing the entropies of the AFM and nonpolarized states in terms of the effective masses are formulated, including low and high temperature limits. It is shown that the unexpected temperature behavior of the entropy of the AFM spin state at low temperatures is caused by the violation of the corresponding low temperature criterium.

description: We provide preliminary quantitative evidence that a new solution to averaging the observed inhomogeneous structure of matter in the universe [gr-qc/0702082, arxiv:0709.0732], may lead to an observationally viable cosmology without exotic dark energy. We find parameters which simultaneously satisfy three independent tests: the match to the angular scale of the sound horizon detected in the cosmic microwave background anisotropy spectrum; the effective comoving baryon acoustic oscillation scale detected in galaxy clustering statistics; and type Ia supernova luminosity distances. Independently of the supernova data, concordance is obtained for a value of the Hubble constant which agrees with the measurement of the Hubble Key team of Sandage et al [astro-ph/0603647]. Best-fit parameters include a global average Hubble constant H_0 = 61.7 (+1.2/-1.1) km/s/Mpc, a present epoch void volume fraction of f_{v0} = 0.76 (+0.12/-0.09), and an age of the universe of 14.7 (+0.7/-0.5) billion years as measured by observers in galaxies. The mass ratio of non-baryonic dark matter to baryonic matter is 3.1 (+2.5/-2.4), computed with a baryon-to-photon ratio that concords with primordial lithium abundances.

description: We have studied the effects of ionizing irradiation from a 60Co source and the effects of neutron irradiation on a Monolithic Active Pixel Sensor Chip(MIMOSA8). A previous report was devoted solely to the neutron-induced effects. We show that extended defects due to the neutron damage changes the distribution of the pixels pedestals. This is mainly due to the increase of the dark generation current due to the presence of deep traps in the depleted zones of the sensors. Alternatively, the exposure to ionizing irradiation increases the pedestals in a more homogeneous way, this coming from the generation of interface states at the Si/SiO2 interface supplemented by the presence of positively charged traps in the oxides. the sensors' leakage current is then increased. We discuss the results in view of increasing the radiation-hardness of the MAPS, bearing in mind that these chips were not designed with any rad-tol layout technique.

This paper aims to present a technique to estimate the losses of a dry-type air-core reactor assembled with one cylinder based on calorimetry principles while employing infrared thermography techniques.
This paper aims to present a technique to estimate the losses of a dry-type air-core reactor (DTACR) assembled with one cylinder based on calorimetry principles while employing infrared thermography techniques. The technique is intuitive, practical, and easy to apply both in a laboratory and in the field. Nowadays, the losses on DTACR can be measured only inside of specific laboratories and the equipment shall be disconnected from system and powered-off. Instead of installing contact temperature sensors in the reactor's internal and external surfaces, temperature measurements were remotely performed with equipment in regular operation and the losses can be obtained by the method proposed. The paper presents the nature of the losses and the theoretical basis of the proposed method. The results obtained from the proposed technique are compared to those achieved by the standard method and used to calculate results through tests performed on prototypes.

description: Nucleosynthesis processes involve reactions on several thousand nuclei, both close to and far off stability. The preparation of reaction rates to be used in astrophysical investigations requires experimental and theoretical input. In this context, two interesting aspects are discussed: (i) the relevant gamma transition energies in astrophysical capture reactions, and (ii) the newly discovered Coulomb suppression of the stellar enhancement factor. The latter makes a number of reactions with negative Q value more favorable for experimental investigation than their inverse reactions, contrary to common belief.

Allocation of outdoor recreation across a mine waste section
Creators: name: Rouse, Clayton Karl
Publisher: name: University of British Columbia
Year: 2010

description: The objective of this thesis was to test multi-attribute utility analysis as a method to help a planner allocate outdoor recreational activities across a mine waste section. The mine waste examined was a hypothetical 10 km x 10 km section. The physical features of the mine waste resemble the coal mine waste of the Elk River Valley in southeastern British Columbia. Nine activities were chosen for examination. These were trailbiking, four-wheel driving, snowmobiling, downhill skiing, cross-country skiing, snowshoeing, hiking, horseback riding and recreational vehicle camping. The activities were grouped into sixteen land uses. A resident of the Elk River Valley was chosen to represent the interests of each activity user group. These interests were described as preferences for attributes of the mine waste. Multi-attribute utility analysis was used to develop the nine representatives' preference structures for the mine waste attributes. The results of the analysis were used to develop an objective function which measured how well a recreation plan for the mine waste satisfied the user groups' interests. A computer program was developed to evaluate the objective function. Using this program, a recreation land use plan was produced for the hypothetical mine waste section which maximized the value of the objective function. Two limitations of the multi-attribute utility analysis were identified in this study. The first was the large time commitment required by user groups to structure their preferences for the mine waste attributes. This resulted in user groups becoming tired with the preference assessment procedure. The second limitation was that the assessed preferences did not take into account the cost to the user groups of obtaining each attribute level. These two factors may influence user groups' preference structures for the mine waste attributes. Accepting these limitations, multi-attribute utility analysis in this study was successful in breaking the large outdoor recreation planning problem into smaller problems where user groups' objectives and associated attributes were identified. The analysis enabled user groups to systematically articulate and understand their preferences for each of the attributes. Using this information, a planner was able to isolate agreements and differences in the preferences of the user groups, which provided a firm basis on which to begin a process of conflict resolution. A planner is then able to incorporate these results with other information on the mine waste development area to develop a feasible outdoor recreation land use plan.

description: We present in this article a new evaluation method for classification and segmentation of textured images in uncertain environments. In uncertain environments, real classes and boundaries are known with only a partial certainty given by the experts. Most of the time, in many presented papers, only classification or only segmentation are considered and evaluated. Here, we propose to take into account both the classification and segmentation results according to the certainty given by the experts. We present the results of this method on a fusion of classifiers of sonar images for a seabed characterization.

description: Aims: To determine the metallicities of 113 Southern Hemisphere Vega-like candidate stars in relation to the Exoplanet host group and field stars. Methods: We applied two spectroscopic methods of abundance determinations: equivalent width measurements together with the ATLAS9 (Kurucz 1993) model atmospheres and the WIDTH9 program, and a comparison of observed spectra with the grid of synthetic spectra of Munari et al. (2005). Results: For the Vega-like group, the metallicities are indistinguishable from those of field stars not known to be associated with planets or disks. This result is quite different from the metallicities of Exoplanet host stars which are metal-rich in comparison to field stars.

description: We derive stability conditions for the critical points of the no-scale scalar potential governing the dynamics of the complex structure moduli and the axio-dilaton in compactifications of type IIB string theory on Calabi-Yau three-folds. We discuss a concrete example of a T^6 orientifold. We then consider the four-dimensional theory obtained from compactifications of type IIB string theory on non-geometric backgrounds which are mirror to rigid Calabi-Yau manifolds and show that the complex structure moduli fields can be stabilized in terms of H_{RR} only, i.e. with no need of orientifold projection. The stabilization of all the fields at weak coupling, including the axio-dilaton, may require to break supersymmetry in the presence of H_{NS} flux or corrections to the scalar potential.

description: The results of micro-Raman scattering measurements performed on three different ``graphitic'' materials: micro-structured disks of highly oriented pyrolytic graphite, graphene multi-layers thermally decomposed from carbon terminated surface of 4H-SiC and an exfoliated graphene monolayer are presented. Despite its multi-layer character, most parts of the surface of the graphitized SiC substrates shows a single-component, Lorentzian shape, double resonance Raman feature in striking similarity to the case of a single graphene monolayer. Our observation suggests a very weak electronic coupling between graphitic layers on the SiC surface, which therefore can be considered to be graphene multi-layers with a simple (Dirac-like) band structure.

description: The impurities of exchange couplings, external magnetic fields and Dzyaloshinskii--Moriya (DM) interaction considered as Gaussian distribution, the entanglement in one-dimensional random $XY$ spin systems is investigated by the method of solving the different spin-spin correlation functions and the average magnetization per spin. The entanglement dynamics at central locations of ferromagnetic and antiferromagnetic chains have been studied by varying the three impurities and the strength of DM interaction. (i) For ferromagnetic spin chain, the weak DM interaction can improve the amount of entanglement to a large value, and the impurities have the opposite effect on the entanglement below and above critical DM interaction. (ii) For antiferromagnetic spin chain, DM interaction can enhance the entanglement to a steady value. Our results imply that DM interaction strength, the impurity and exchange couplings (or magnetic field) play competing roles in enhancing quantum entanglement.

This paper contains several test systems including the load data, network configuration, line characteristics, maximum current of branches, and nominal powers and voltages. The main objective is to provide all the details and information required to evaluate models and methods developed for reconfiguration and operation of radial distribution systems.
Nowadays, specialized literature uses different test systems to verify their proposed models and methodologies regarding reconfiguration and operation of distribution networks. However, none of these research works include various test systems with enough information in order to endorse studies that approach distribution system reconfiguration and operation issues. This paper contains several test systems including the load data, network configuration, line characteristics, maximum current of branches, and nominal powers and voltages. The main objective is to provide all the details and information required to evaluate models and methods developed for reconfiguration and operation of radial distribution systems. Verification of all presented data and information has been performed by solving the network reconfiguration problem using established techniques. Moreover, in order to check the radiality of test systems and correctness of their given data, a data visualization technique is employed to online depict network topologies based on the electrical distance between buses.

We present a new grid planning method and use it to find the trade-off between Active Power Curtailment and grid reinforcement in a case study of a High-Voltage grid with a future renewable energy scenario.
In regions with high penetration of Distributed Energy Resources (DER), grid congestion is mostly caused by power feed-in of generators. In this context, conventional approaches for solving the grid congestion problems are Active Power Curtailment (APC) of DER and grid reinforcement. In the wake of increased DER generation, it is not only of interest how to obtain the grid reinforcement, but also how to consider APC during grid planning. The challenge of such grid planning is to determine the best combination of reinforcement and APC. We present a new grid planning method and use it to find the trade-off between APC and grid reinforcement in a case study of a High-Voltage (HV) grid with a future renewable energy scenario. We compare the proposed reinforcement method to two existing methods. With the combination of APC and grid reinforcement, the proposed method shows a decrease regarding the total expenditures.
