description: Combining scattering matrix theory with non-linear $σ$-model and Keldysh technique we develop a unified theoretical approach enabling one to non-perturbatively study the effect of electron-electron interactions on weak localization and Aharonov-Bohm oscillations in arbitrary arrays of quantum dots. Our model embraces (i) weakly disordered conductors (ii) strongly disordered conductors and (iii) metallic quantum dots. In all these cases at $T \to 0$ the electron decoherence time is found to saturate to a finite value determined by the universal formula which agrees quantitatively with numerous experimental results. Our analysis provides overwhelming evidence in favor of electron-electron interactions as a universal mechanism for zero temperature electron decoherence in disordered conductors.

description: The application of VLBI to scientific problems has undergone a relentless expansion since its conception, yet the potential for further expansion is still large. We are on the cusp of revolutionary progress given the arrival of a host of next-generation instruments. Over the last few years the community has been working hard to ensure the SKA design includes the capability to enable multiple simultaneous tied-array beams, which is a crucial technology to deliver ultra-precise astrometry and improve survey speed capabilities. However, to reach the full potential requires that the network of antennas is upgraded to match the SKA capabilities. We identify multiple-pixel technology, on large telescopes and connected arrays, as a crucial missing component and here will make recommendations for the upgrade path of the partner EVN (and other network) telescopes. Our feasibility studies on SKA-VLBI suggest an order of magnitude improvement in the precision and also in the frequency range at which astrometry can be performed today, if the full network has the required capabilities.

description: We report investigation of structural phase transitions in technologically important material sodium niobate as a function of temperature on heating over 300-1075 K. Our high resolution powder neutron diffraction data show variety of structural phase transitions ranging from non-polar antiferrodistortive to ferroelectric and antiferroelectric in nature. Discontinuous jump in lattice parameters is found only at 633 K that indicates that the transition of orthorhombic antiferroelectric P (space group Pbcm) to R (space group Pbnm) phase is first order in nature, while other successive phase transitions are of second order. New superlattice reflections appear at 680 K (R phase) and 770 K (S phase) that could be indexed using an intermediate long-period modulated orthorhombic structure whose lattice parameter along <001> direction is 3 and 6 times that of the CaTiO3-like Pbnm structure respectively. The correlation of superlattice reflections with the phonon instability is discussed. The critical exponent (β) for the second order tetragonal to cubic phase transition at 950 K, corresponds to a value β$\approx 1/3$, as obtained from the temperature variation of order parameters (tilt angle and intensity of superlattice reflections). It is argued that this exponent is due to a second order phase transition close to a tricritical point. Based on our detailed temperature dependent neutron diffraction studies, the phase diagram of sodium niobate is presented that resolves existing ambiguities in the literature.

Modeling dam removal in a mountain meadow with MODFLOW-NWT
Creators: name: Eyster, Theodore
Publisher: name: University of British Columbia
Year: 2019

description: Dam removal has been occurring across the United States as old infrastructure deteriorates and as people recognize the environmental disruptions dams create. Although dam removal projects are becoming more common, studies on their impacts, particularly on groundwater, are limited. A planned dam removal project on Van Norden Meadow, in the California Sierra Nevada Range at Donner Pass, provides an excellent case study to consider dam removal impacts on shallow groundwater in the associated meadow system. Mountain meadows are a valuable resource in California’s Sierra Nevada range, providing an important source of water, supporting natural communities, and serving as a climate change refugia. Using MODFLOW, an open-source finite-difference groundwater modeling program, I established a baseline groundwater model for Van Norden Meadow and assessed potential dam removal impacts on plant vegetation communities and subsurface water balance. Model layers were derived from surface topography, interpolated depth-to-bedrock, and literature values. Hydraulic parameters were calibrated and validated using summer groundwater levels from 28 monitoring wells in 2016 and 2017. After calibration, the lower meadow (below a recessional moraine) showed both the thickest sediments (up to 36 m) and the highest calibrated hydraulic conductivity (70 m/d). Dam removal was simulated using data from summer 2016 with altered reservoir boundary conditions. The model predicted a slight decrease in the water table of the lower meadow and no impact to the water table in the upper meadow (above the moraine)—influenced by modeled transmissivity. The areas most at risk of losing wet meadow vegetation are those adjacent to the dam along the reservoir footprint. The model also suggested that in the absence of other measures, dam removal will lead to increased mobilization of stored groundwater to baseflow drainage below the meadow (on average 3% from May to October). This increase is partially offset by decreased evapotranspiration from the model area (on average 8% from May to October). While no actions may be needed in the upper meadow, restoration activities, such as channel filling, pond-and-plug, or beaver dam analogs, may offset both the decrease in the water table and promote wet meadow habitats in the lower meadow.

description: We develop a solution theory for a generalized electro-magneto static Maxwell system in an exterior domain with anisotropic coefficients converging at infinity with a certain rate towards the identity. Our main goal is to treat right hand side data from some polynomially weighted Sobolev spaces and obtain solutions which are up to a finite sum of special generalized spherical harmonics in another appropriately weighted Sobolev space. As a byproduct we prove a generalized spherical harmonics expansion suited for Maxwell equations. In particular, our solution theory will allow us to give meaning to higher powers of a special static solution operator. Finally we show, how this weighted static solution theory can be extended to handle inhomogeneous boundary data as well. This paper is the second one in a series of three papers, which will completely reveal the low frequency behavior of solutions of the time-harmonic Maxwell equations.

description: The analysis of a previous paper, in which it was shown that the energy for the Aharonov-Bohm effect could be traced to the interaction energy between the magnetic field of the electron and the background magnetic field, is extended to cover the case in which the magnetic field of the electron is shielded from the background magnetic field by superconducting material. The paradox that arises from the fact that such a shielding would apparently preclude the possibility of an interaction energy is resolved and, within the limits of the ideal situation considered, the observed experimental result is derived.

description: A novel time delayed chaotic oscillator exhibiting mono- and double scroll complex chaotic attractors is designed. This circuit consists of only a few operational amplifiers and diodes and employs a threshold controller for flexibility. It efficiently implements a piecewise linear function. The control of piecewise linear function facilitates controlling the shape of the attractors. This is demonstrated by constructing the phase portraits of the attractors through numerical simulations and hardware experiments. Based on these studies, we find that this circuit can produce multi-scroll chaotic attractors by just introducing more number of threshold values.

description: On the Large Phased Array (LPA) of Lebedev Physics Institute (LPI), a search for pulsars outside the Galaxy plane was carried out in a 300 sq. deg area. The search with a sensitivity 5-10 times better than that of previously conducted surveys was at a frequency of 111 MHz. The search was carried out in the summed power spectra. With an accumulation equivalent to 100 hours of continuous observations for each point of the area, 5 known pulsars were detected with a signal-to-noise ratio (S/N) from 20 to 1300 in the first harmonic of the spectrum. Average profiles were obtained for the detected pulsars. Estimates of the peak and integral flux densities of the found pulsars are given for individual sessions and for the power spectra summarized over 5.5 years, obtained using the developed method based on measurements of the height of harmonics in the power spectrum. No new pulsars have been detected in the area. Apparently, when searching for pulsars in the area, we have approached the lower limit of the luminosity of the second pulsars. The completeness of the survey is at the level of 0.5 mJy.

description: In this paper, we examine the possibility to implement some form of emergent Newtonian gravity in a generic multi-component Bose--Einstein condensate. Parallely to what happens for the emergence of low energy Lorentz invariance, strong requirements have to be imposed on the underlying condensed matter model. We will show, within a simplified model, that the presence of a global symmetry alleviates the problems associated to Lorentz violation, allows the presence of a long range potential, to which the analogue matter fields (the quasi-particles) are coupled following a weaker form of equivalence principle.

description: Земляника садовая — одна из наиболее рентабельных и экономически выгодных ягодных культур в мире. Помимо потребления в свежем виде, данная культура находит широкое применение в качестве сырья для переработки, консервирования и замораживания. Причина столь разнообразного применения ягод земляники заключается в ее химическом составе. Плоды быстрой заморозки после дефростации используют в консервной промышленности, в производстве винных напитков, плодовых водок, настоек сладких. Использование замороженных плодов после дефростации возможно и для производства высококачественных фруктовых вин и сидров. Органические кислоты влияют на формирование вкуса вина, участвуют в создании его букета, придают приятную свежесть и предохраняют от различного рода заболеваний. Целью настоящего исследования стало изучение изменения состава органических кислот фруктовых соков и виноматериалов, полученных из ягод земляники садовой, замороженных при трех различных температурах: –12, –18, –35 °С. Все ягоды после замораживания закладывали на хранение в течение 1 мес. при температуре –18 °С. Замороженные плоды подвергали дефростации тремя способами: на воздухе; в холодильной камере; в СВЧ-печи. В результате проведенных исследований установлено, что качественный состав органических кислот во всех образцах виноматериалов из свежих и дефростированных ягод земляники садовой отличается незначительно и в основном представлен лимонной, яблочной, янтарной и щавелевой кислотами. Количественное содержание органических кислот различается накоплением яблочной кислоты в виноматериалах в результате брожения сусла из дефростированных ягод, тогда как при брожении сусла из свежих ягод содержание яблочной кислоты уменьшается. Также отмечены существенные различия в синтезе янтарной кислоты, ее концентрация в контрольном виноматериале в 2 раза выше, чем в виноматериалах из дефростированных ягод. В среднем, общее содержание органических кислот в виноматериалах из свежих ягод ниже на 2,2 г/дм3, чем в опытных образцах из дефростированной земляники. Вероятно, такие различия в накоплении органических кислот вызваны активизацией ферментов, спецификой метаболических процессов, интенсификацией и изменением последовательности биохимических реакций в результате замораживания и последующей дефростации ягод земляники.

description: We discuss the equations for the bound one-active electron states based on the analytic solutions of the Schrodinger and Pauli equations for a uniform magnetic field and a single attractive $δ({\bf r})$-potential. It is vary important that ground electron states in the magnetic field differ essentially from the analogous state of spin-0 particles, whose binding energy was intensively studied more than forty years ago. We show that binding energy equations for spin-1/2 particles can be obtained without using the language of boundary conditions in the $δ$-potential model developed in pioneering works. We use the obtained equations to calculate the energy level displacements analytically and demonstrate nonlinear dependencies on field intensity. We show that the magnetic field indeed plays a stabilizing role in considered systems in a case of the weak intensity, but the opposite occurs in the case of strong intensity. These properties may be important for real quantum mechanical fermionic systems in two and three dimensions. We also analyze the exact solution of the Pauli equation for an electron moving in the potential field determined by the three-dimensional $δ$-well in the presence of a strong magnetic field. We obtain asymptotic expressions for this solution for different values of the problem parameters. In addition, we consider electron probability currents and their dependence on the magnetic field. We show that including the spin in the framework of the nonrelativistic approach allows correctly taking the effect of the magnetic field on the electric current into account. The obtained dependencies of the current distribution, which is an experimentally observable quantity, can be manifested directly in scattering processes, for example.

description: Цель работы состояла в научном обосновании разработки дополнительных критериев оценки качества красных виноматериалов для игристых вин на основе сравнительной оценки влияния физико-химического состава исходной тиражной смеси на процесс вторичного брожения. В качестве объектов исследования использовали четыре образца тиражной смеси, приготовленные из красных и розовых сухих столовых виноматериалов, произведенных на предприятиях Российской Федерации. Подготовку тиражной смеси и вторичное брожение в бутылках проводили в соответствии с действующей нормативной документацией. В процессе вторичного брожения контролировали давление диоксида углерода в бутылке, а также изменение крепости, массовой концентрации сахаров, аминного и аммиачного азота, титруемой кислотности, рН, ОВП, динамической устойчивости двусторонней пленки шампанизируемого вина. Установлено, что наиболее интенсивно вторичное брожение проходило в образцах с массовой концентрацией фенольных веществ в исходном купаже в диапазоне от 1129 до 1635 мг/дм3 и суммарной концентрацией азотистых соединений в пределах 730–750 мг/дм3, что позволило получить игристое вино с высокими органолептическими показателями. Результаты исследования показали, что на процессы вторичного брожения при производстве красных игристых вин в наибольшей степени оказывают влияние массовая концентрация фенольных и азотистых соединений, присутствующих в исходных виноматериалах и тиражной смеси. Полученные данные показали необходимость проведения более глубоких исследований, направленных на определение пределов варьирования таких дополнительных показателей качества исходных красных виноматериалов, как массовая концентрация фенольных веществ, аминного и аммиачного азота и суммы свободных аминокислот.

description: We consider a nonlinear microcavity separating a waveguide channel into two parts so as the coupling between them is possible only due to the resonant properties of the microcavity. We provide a rigorous derivation of the equations used in the phenomenological coupled mode theory for such systems. This allows us to find the explicit formulas for all fitting parameters such as decay rates, coupling coefficients and characteristic intensities in terms of the mode profiles. The advantages of using the semi-analytical approach are discussed, and the accuracy of the results is compared with the strictly numerical methods. A particular attention is paid to multilayered structures since they represent the simplest realization of on-channel microcavities.

description: Во всем мире питьевая вода становится все более дефицитным ресурсом из‑за чрезмерного использования и загрязнения окружающей среды. Доступ к чистой и безопасной питьевой воде, по определению ООН, — одно из основных прав человека. В 2019 г. в России потребление упакованной воды составило 50,7 л на человека в год, по сравнению с 100 л в странах Европы. С 1 января 2019 г. в странах Евразийского экономического союза вступил в действие технический регламент ТР ЕАЭС 044/2017 «О безопасности упакованной питьевой воды, включая природные минеральные воды». За время переходного периода в Регламенте был выявлен ряд позиций, которые нуждаются в уточнении и корректировке. В статье рассматриваются отдельные вопросы по минеральным водам: содержание марганца и природных радионуклидов в лечебно-столовых и лечебных минеральных водах, отсутствие лечебного действия новых групп (фторидная и слабокремнистая) лечебно-столовых минеральных вод. Рассмотрена проблема выявления фальсифицированных упакованных минеральных и питьевых вод. Предлагаемый путь решения проблемы появления на рынке фальсификата — это создание Национальной системы идентификации, которая включает разработку цифровых профилей природных минеральных и питьевых вод и введение комплекса оценочных критериев, позволяющих с высокой степенью достоверности идентифицировать их. Работа по созданию реестра и базы данных предполагает большой массив мониторинга качества воды по более чем 50 показателям качества. Полученные результаты станут основой для создания цифрового профиля источника и готовой продукции. Национальная система идентификации позволит систематизировать все упакованные природные как минеральные, так и питьевые воды, а главное, создаст условия для защиты прав потребителей и обеспечения населения России качественной и безопасной упакованной питьевой водой.

description: Pharmaceutical and non-pharmaceutical interventions (NPIs) have been crucial for controlling COVID-19. They are complemented by voluntary health-protective behaviour, building a complex interplay between risk perception, behaviour, and disease spread. We studied how voluntary health-protective behaviour and vaccination willingness impact the long-term dynamics. We analysed how different levels of mandatory NPIs determine how individuals use their leeway for voluntary actions. If mandatory NPIs are too weak, COVID-19 incidence will surge, implying high morbidity and mortality before individuals react; if they are too strong, one expects a rebound wave once restrictions are lifted, challenging the transition to endemicity. Conversely, moderate mandatory NPIs give individuals time and room to adapt their level of caution, mitigating disease spread effectively. When complemented with high vaccination rates, this also offers a robust way to limit the impacts of the Omicron variant of concern. Altogether, our work highlights the importance of appropriate mandatory NPIs to maximise the impact of individual voluntary actions in pandemic control.

The experiences of complicated-mild to severe traumatic brain injury survivors in counselling
Creators: name: Leong, Angela Ivy
Publisher: name: University of British Columbia
Year: 2019

description: After traumatic brain injury (TBI), survivors often struggle with emotional issues such as low mood, anxiety, anger, a “shattered sense of self” and grief (Ruff & Chester, 2014; Levack, Kayes & Fadyl, 2010; Aboulafia-Brakha, Greber-Buschbeck, Rochat & Annoni, 2013). The complicity of these issues, which do not respond well to medication, has led to the rise of psychological counselling in rehabilitation. Due to massive neurobehavioural differences between TBI survivors and the general population, research-validated counselling practices are needed. The American Psychological Association (2006) states that research-validated practice is to be comprised of clinical expertise, controlled studies and client feedback. However, the literature describing best practices for TBI survivors in counselling is dominated by theoretical guidelines based on clinical expertise. This study aims to fulfill the gap in the lack of feedback from survivors regarding treatment received. A qualitative method was used. Ten participants were recruited through posters posted in various establishments in Metro Vancouver. Using the Interpretive Description method, participants were asked to provide an in-depth description of helpful and unhelpful experiences in counselling, including their experiences of the interventions used, their relationship with their therapist, and any environmental factors experienced. The inquiry was guided by semi-structured interview questions, which were developed and re-developed with the cumulative data from each successive participant. Participant descriptions were interpreted, coded and analyzed, from which three major sub-themes of data emerged: participant descriptions of barriers and facilitators in the therapeutic environment, in the therapeutic relationship and in the components of psychotherapeutic treatment.

description: We develop a simple and scalable graphene patterning method using electron-beam or ultraviolet lithography followed by a lift-off process. This method, with the merits of: high pattern resolution and high alignment accuracy, free from additional etching or harsh process, universal to arbitrary substrates, compatible to Si microelectronic technology, can be easily applied to diverse graphene-based devices, especially in array-based applications, where large-scale graphene patterns are desired. We have applied this method to fabricate CdSe nanobelt (NB)/graphene Schottky junction solar cells, which have potential application in integrated nano-optoelectronic systems. Typical as-fabricated solar cell shows excellent photovoltaic behavior with an open-circuit voltage of ~ 0.51 V, a short-circuit current density of ~ 5.75 mA/cm2, and an energy conversion efficiency of ~1.25%. We attribute the high performance of the cell to the as-patterned high-performance graphene, which can form an ideal Schottky contact with CdSe NB. Our results suggest both the developed graphene patterning method and the as-fabricated CdSe nanobelt (NB)/graphene Schottky junction solar cells have reachable application prospect.

description: If the 20th century was known for the computational revolution, what will the 21st be known for? Perhaps the recent strides in the nascent fields of molecular programming and biological computation will help bring about the 'Coming Era of Nanotechnology' promised in Drexler's 'Engines of Creation'. Though there is still far to go, there is much reason for optimism. This thesis examines the underlying principles needed to realise the computational aspects of such 'engines' in a performant way. Its main body focusses on the ways in which thermodynamics constrains the operation and design of such systems, and it ends with the proposal of a model of computation appropriate for exploiting these constraints. These thermodynamic constraints are approached from three different directions. The first considers the maximum possible aggregate performance of a system of computers of given volume, $V$, with a given supply of free energy. From this perspective, reversible computing is imperative in order to circumvent the Landauer limit. A result of Frank is refined and strengthened, showing that the adiabatic regime reversible computer performance is the best possible for any computer - quantum or classical. This therefore shows a universal scaling law governing the performance of compact computers of $\sim V^{5/6}$, compared to $\sim V^{2/3}$ for conventional computers. For the case of molecular computers, it is shown how to attain this bound. The second direction extends this performance analysis to the case where individual computational particles or sub-units can interact with one another. The third extends it to interactions with shared, non-computational parts of the system. It is found that accommodating these interactions in molecular computers imposes a performance penalty that undermines the earlier scaling result. Nonetheless, scaling superior to that of irreversible computers can be...

description: Quantum discord witnesses the nonclassicality of quantum states even when there is no entanglement in these quantum states. This type of quantum correlation also has some interesting and significant applications in quantum information processing. Quantum discord has been evaluated explicitly only for certain class of two-qubit states. We extend the previous studies to $2 \otimes d$ quantum systems and derive an analytical expression for quantum discord for a two-parameter class of states for $d \geq 3$. We compare quantum discord, classical correlation, and entanglement for qubit-qutrit systems to demonstrate that different measures of quantum correlation are not identical and conceptually different.

description: We propose a polarization to orbital angular momentum teleportation scheme using entangled photon pairs generated by spontaneous parametric down conversion. By making a joint detection of the polarization and angular momentum parity of a single photon, we are able to detect all the Bell-states and perform, in principle, perfect teleportation from a discrete to a continuous system using minimal resources. The proposed protocol implementation demands experimental resources that are currently available in quantum optics laboratories.

description: Концентрация метанола в спиртных напитках на основе фруктовых дистиллятов значительно выше, чем в коньяке, виски или роме. Она зависит как от вида фруктового сырья, так и от особенностей принятой технологии. Настоящая работа посвящена изучению влияния физико-химического состава сброженной кизиловой мезги на динамику изменения концентрации метанола при ее дистилляции, а также определению режимных параметров дистилляции, обеспечивающих минимальное содержание метанола в дистилляте. Объектами исследования служили образцы сброженной кизиловой мезги, закрепленные этиловым спиртом-ректификатом до различной крепости; сброженная мезга, закрепленная кизиловым дистиллятом; а также образцы фракций дистиллятов. Установлено, что при дистилляции кизиловой мезги концентрация метанола снижается в начальный период и резко возрастает в конце дистилляции — в хвостовой фракции. Минимальная концентрация метанола в течение всего процесса зафиксирована при дистилляции мезги, закрепленной этиловым спиртом до 18–24 % об. Добавление в мезгу перед дистилляцией кизилового дистиллята от предыдущей перегонки привело к изменению характера кривой накопления метанола. В этом случае он концентрировался в большей степени в средней фракции. Показано положительное влияние задержки флегмы и снижения скорости дистилляции на динамику изменения концентрации метанола в средней фракции дистиллята. Определены следующие режимные параметры дистилляции, обеспечивающие минимальное содержание метанола в продукте: дистилляция с задержкой флегмы на нижней тарелке укрепляющей колонны при скорости 5,5–3,4 см3/мин.

description: В технологии производства безалкогольной и слабоалкогольной продукции в соответствии с ТР ТС 029/2012 «Требования безопасности пищевых добавок, ароматизаторов и технологических вспомогательных средств» для повышения микробиологической стабильности разрешено использовать пищевые добавки: консервант Е220 (сорбиновая кислота, СК) и растворимые соли сорбиновой кислоты, консервант Е210 (бензойная кислота, БК) и ее растворимые соли. Концентрации вносимых в продукцию СК, БК и их солей ограничены. Для контроля содержания СК и БК в настоящее время на территории РФ применяют стандартные методы, использующие метод капиллярного электрофореза (СКЭФ) или высокоэффективную жидкостную хроматографию (ВЭЖХ). Применение СКЭФ и ВЭЖХ требует достаточно дорогостоящего специального оборудования и расходных материалов, специально обученного персонала для работы на этих приборах. Анализ действующих методов определения СК и БК в напитках показал, что определение указанных выше пищевых добавок в образцах безалкогольной продукции (БАП) и слабоалкогольной продукции (САП) с использованием спектрофотометрии не требует специальных расходных материалов и дорогостоящего оборудования, поэтому был выбран спектрофотометрический метод определения этих консервантов. Приведены метрологические характеристики разработанного спектрофотометрического метода определения массовой концентрации сорбиновой и бензойной кислот в слабоалкогольной и безалкогольной продукции, в том числе метрологические характеристики аттестованных смесей СК и БК различной концентрации. Разработанная методика зарегистрирована в Федеральном информационном фонде по обеспечению единства измерений.

description: We study in detail Hodge-Helmholtz decompositions in non-smooth exterior domains filled with inhomogeneous and anisotropic media. We show decompositions of alternating differential forms belonging to weighted Sobolev spaces into irrotational and solenoidal forms. These decompositions are essential tools, for example, in electro-magnetic theory for exterior domains. In the appendix we translate our results to the classical framework of vector analysis.

description: The spontaneous decay of an excited state of an emitter placed in the vicinity of a metallic single-wall carbon nanotube (SWNT) was examined theoretically. The emitter-SWNT coupling strongly depends on the position of the emitter relative to the SWNT, the length of the SWNT, the dipole transition frequency and the orientation of the emitter. In the high-frequency regime, dips in the spectrum of the spontaneous decay rate exist at the resonance frequencies in the spectrum of the SWNT conductivity. In the intermediate-frequency regime, the SWNT conductivity is very low, and the spontaneous decay rate is practically unaffected by the SWNT. In the low-frequency regime, the spectrum of the spontaneous decay rate contains resonances at the antennas resonance frequencies for surface-wave propagation in the SWNT. Enhancement of both the total and radiative spontaneous decay rates by several orders in magnitude is predicted at these resonance frequencies. The strong emitter-field coupling is achieved, in spite of the low Q factor of the antenna resonances, due to the very high magnitude of the electromagnetic field in the near-field zone. The vacuum Rabi oscillations of the population of the excited emitter state are exhibited when the emitter is coupled to an antenna resonance of the SWNT.
