description: We introduce a measure Q of bipartite quantum correlations for arbitrary two-qubit states, expressed as a state-independent function of the density matrix elements. The amount of quantum correlations can be quantified experimentally by measuring the expectation value of a small set of observables on up to four copies of the state, without the need for a full tomography. We extend the measure to 2 x d systems, providing its explicit form in terms of observables and applying it to the relevant class of multiqubit states employed in the deterministic quantum computation with one quantum bit model. The number of required measurements to determine Q in our scheme does not increase with d. Our results provide an experimentally friendly framework to estimate quantitatively the degree of general quantum correlations in composite systems.

description: This paper reports experimental results of RF characteristics up to 20 GHz of a RF MEMS switch applied with wafer level packaging. A glass wafer is used as a package substrate on which frit glass is printed as material to seal the MEMS devices. The package wafer is bonded to a device wafer, which consists of actuators and base substrates .The actuators are made of single crystal silicon that has less residual stress. The base substrate has through holes formed by sand blast. The switch achieves a low insertion loss of 1.3 dB and a high isolation of 19 dB up to 20 GHz, and can be mounted on to a circuit board with bumps, like flip chip. The wafer level packaging with low cost and high reliability will transfer RF MEMS devices, which has superior high frequency characteristics even in quasi-millimeter wave band, to the practical use.

description: We assess experimentally the suitability of coupled transmission line resonators for studies of quantum phase transitions of light. We have measured devices with low photon hopping rates t/2pi = 0.8MHz to quantify disorder in individual cavity frequencies. The observed disorder is consistent with small imperfections in fabrication. We studied the dependence of the disorder on transmission line geometry and used our results to fabricate devices with disorder less than two parts in 10^4. The normal mode spectrum of devices with a high photon hopping rate t/2pi = 31MHz shows little effect of disorder, rendering resonator arrays a good backbone for the study of condensed matter physics with photons.
A simple condition for maximum bandwidth of a chip packaged in an mm-wave waveguide

description: Waveguides can be used as both packaging cases and interconnection media between chips. No bond wires are needed in this packaging technique and, consequently, it can be used in millimetre wave circuits and systems. However, a chip inserted in a waveguide introduces additional unwanted propagation modes and reduces an effective bandwidth of the structure. A simple condition for an optimum placement of the chip to maximise the bandwidth is derived and confirmed by a rigorous 3-D electromagnetic simulation of WR6 and WR10 waveguide packages for typical GaAs and InP chip dimensions.

description: No abstracts are to be cited without prior reference to the author.By-catch and discards are recognized as major issues of worldwide fisheries. More selective fishing methods that harvest only usable fish are considered as a solution for greatly reducing by-catch. But more selective fisheries might conflict with another goal of modern fisheries management: to harvest in ways that do not impede ecosystem structure and function. The idea has been put forward that exploitation should be balanced across trophic levels to maintain ecosystem trophic structure. Are selective fisheries targeting restricted but potentially key components of a community more harmful to community functioning than non-selective exploitation that evenly harvests from most parts of the community? We present theoretical predictions of the contrasted effects of selective versus even fishing on exploited communities, using two modelling approaches. First, we used a biomass size spectrum model describing the distribution of biomass across body size classes. Simulations with a time-dependent continuous model in which the energy flow is governed by size-dependent predation, suggest that selective fishing targeting a restricted size range in the community generates oscillatory dynamics with a wider amplitude than less-selective fishing, especially when large fish are targeted; in addition, size diversity is lower with size-selective fishing. Second, we parameterized LeMANS, an existing, length-based multispecies model designed to evaluate community responses to fishing, for Georges Bank and the North Sea. Simulations show that community metrics such as species evenness and size diversity generally decrease as the number of species fished increase. However, for a similar catch, the metrics are always higher when fishing unselectively all species than any subset of species.

description: A patient’s illness identity is the degree to which a patient’s diagnosis is integrated into their sense of self. As a frequent point of discussion for providers, physicians often discuss how providers should not call their patients “diabetic patients;” instead, they should use the phrase “patients with type 1 diabetes.” The reminder to providers merely points to the prevalence of how an dillness can become a part of a person’s identity, with a patient’s illness identity impacting a patient’s life in a variety of way, both positive and negative. Although research has begun to show the positive and negative effects of illness identity on health outcomes in a variety of conditions, there is a lack of understanding as to why illness identity has the impact on outcomes that it does. Although attribution theory as a whole is not often studied explicitly in healthcare settings, health locus of control has gained significant attention. Other elements of attribution theory, particularly controllability, can be found in recent research on patient illness representations, or a patient’s common-sense understanding of a health threat. In this paper, I review the state of the current literature on illness identity, attribution theory, and illness representation with a particular focus on controllability in medical patient populations. I end this review with a proposal for a study of pediatric and adolescent patients with type 1 diabetes that has as its goal investigating a possible mediation model. I hypothesize that the effects of illness identity on health outcomes are mediated by a patient’s perception of the controllability of their illness. In my conclusion, I discuss possible applications and further investigations of this mediation model both within and outside of pediatric and adolescent patients with type 1 diabetes.

The Dirac fermionic field appears as the effective field describing the excitations above point-like Fermi surface. Together with the Dirac fermionic field an effective space-time metric is also emerging. We analyze the conditions for such Fermi points to appear in general, paying special attention to the cases of two and three spacial dimensions.

Altered clot formation and anticoagulation in a familial Alzheimer's disease mouse model
Creators: name: Ho, Laura
Publisher: name: University of British Columbia
Year: 2013

description: Alzheimer’s disease (AD) is a progressive neurodegenerative disorder and the leading form of dementia. Its complex etiology is traditionally attributed to an increase in the production and aggregation of amyloid-beta (Aβ). However, vascular risk factors and related disorders are also associated with the development of AD. The mechanism by which these deficiencies lead to neurodegeneration remains unclear. An altered hemostatic state has increasingly been implicated in AD pathogenesis, with the majority of research focusing on the interaction between Aβ and fibrin. It was therefore of interest to assess previously uncharacterized components of coagulation and anticoagulation in a familial AD (FAD) mouse model. Clot formation was initially analyzed using platelet rich plasma, with aged AD mice exhibiting 40% shorter clotting times compared to age-matched controls. Thrombin generation revealed differences attributable to an altered clot integrity. AD mice may form clots composed of a dense network of thin fibrin strands, resistant to fibrinolysis. Correspondingly, antithrombin (AT) activity was also reduced. These changes were subject to age, occurring specifically in aged mice only. These data suggest a change in clot formation and integrity concomitant with the development of AD. The interaction between Aβ and AT was examined in vitro, with Aβ42 and Aβ40 decreasing AT activity in a concentration dependent manner. A clinical study evaluating prothrombotic markers revealed a trend towards lower AT activity in AD patients, though not statistically significant. The changes in clot formation and anticoagulation potentiating a prothrombotic state may be specific to the FAD mouse model, but may still contribute to the elucidation of AD pathogenesis.
Correlation and nonlocality measures as indicators of quantum phase transitions in several critical systems

description: We have investigated the quantum phase transitions in the ground states of several critical systems, including transverse field Ising and XY models as well as XY with multiple spin interactions, XXZ and the collective system Lipkin-Meshkov-Glick models, by using different quantumness measures, such as entanglement of formation, quantum discord, as well as its classical counterpart, measurement-induced disturbance and the Clauser-Horne-Shimony-Holt-Bell function. Measurement-induced disturbance is found to detect the first and second order phase transitions present in these critical systems, while, surprisingly, it is found to fail to signal the infinite-order phase transition present in the XXZ model. Remarkably, the Clauser-Horne-Shimony-Holt-Bell function is found to detect all the phase transitions, even when quantum and classical correlations are zero for the relevant ground state.

description: Academic Research Computing and Data (RCD) as a profession remains in its formative stages. Previous efforts have been made to

define, formalize, and analyze the roles within the profession. Important among those efforts is the creation of the ‘facings’ model.

This study, the third in a series, is a preliminary examination of the relationships between educational background, majority facings,

and the work activities of RCD professionals using data from our prior 2021 RCD workforce national survey. Findings suggest that

new questions must be asked to provide details of RCD Professionals’ work scope, especially facilitator-type roles. A pivotal next step

is to clearly define the knowledge, skills, and characteristics required for individuals to thrive in these positions.

description: With the increase in production volume of RF devices (e.g. for automotive applications), packaging and interconnection become more and more important. Furthermore, new system concepts such as chip-on-chip or RF- MEMS demand new packaging strategies. This paper presents a vertical silicon micromachined RF CPW through- wafer feedthrough with excellent performance in the K-band. In particular, the feedthrough demonstrates an insertion loss of 0.16dB and a return loss of 20dB at 25GHz. A lumped element model was developed and was evaluated with measurements.

description: We provide strong evidence that the S=1 bilinear-biquadratic Heisenberg model with nearest-neighbor interactions on the square lattice possesses an extended three-sublattice phase induced by quantum fluctuations for sufficiently large biquadratic interactions, in spite of the bipartite nature of the lattice. The argumentation relies on exact diagonalizations of finite clusters and on a semiclassical treatment of quantum fluctuations within linear flavor-wave theory. In zero field, this three-sublattice phase is purely quadrupolar, and upon increasing the field it replaces most of the plateau at 1/2 that is predicted by the classical theory.

description: Fragestellung der vorliegenden Arbeit war es, ob der Zusatz von BMP 4 (Bone Morphogenetic Protein) zu dem Bioglass® NovaBone-C/M™ den Knochenheilungsprozess an ossären Defekten von Meerschweinchen zusätzlich beschleunigen kann. BMP 4 ist ein Zytokin aus der Gruppe der Wachstumsfaktoren, die primär verantwortlich für die Entwicklung sowie Reifung von Knorpel- und Knochengewebe sind. Bioglass® ist eine bioaktive Substanz mit osteokonduktiven Eigenschaften. In dieser Studie wurde anhand von 24 Tieren aufgeteilt in drei Gruppen zu je acht Tieren, der Einfluss von BMP 4 dargestellt. Man implantierte den Tieren Bioglass® in vorher geschaffene Defekte der rechten und linken Bulla und Kalotte, dem Bioglass® der linken Seite wurde jeweils das Zytokin BMP 4 zugesetzt. Im Bereich der Kalotte war es möglich, für die Gruppe 1 (vier Wochen; p=0,057) und 2 (acht Wochen; 0,077) eine tendenziell beschleunigte Ossifikation zu ermitteln, ohne jedoch das Signifikanzniveau zu erreichen. Im Bereich der Bulla wurden keine signifikanten Unterschiede ermittelt( für Gruppe 1 und 2). Die Ergebnisse im Bereich der Kalotte deuten an, dass die Kombination eines osteoinduktiven Zytokins (BMP 4) mit einem osteokonduktiven Material (NovaBone-C/M™) als Carriersystem eine viel versprechende Alternative zur konventionellen Behandlung von Knochendefekten ist.

description: Lake sediment cores spanning the last 2000 years from four sites across the Canadian Arctic Archipelago (CAA) document the responses of terrestrial and freshwater ecosystems to regional climate variability. Biogenic silica (BSi) records in cores from Banks Island, NWT (Lake B503; 72.3245, -123.4036, 84 masl), Bathurst Island, Nunavut (PR01; 75.6497, -99.1144, 30 masl), Prince of Wales Island, Nunavut (SW08; 72.3177, -97.2678, 104 masl), and Ellesmere Island, Nunavut (CV03; 79.9211, -82.9348, 363 masl) were used to examine the relationship between diatom production and climate. A pollen record from Prince of Wales Island provided the first high-resolution July temperature reconstruction for the last 1000 years for the central CAA. Dissolution was evident in three out of the four lakes; core SW08 contained no BSi above detection and cores CV03 and PR01 only contained values above detection in the uppermost sediments, suggesting that the preservation of biogenic silica (BSi) in the sediment is likely influenced by sedimentary carbonates. A BSi sequence from core B503 showed that diatom production was affected by climate changes such as the Medieval Climate Anomaly and the Little Ice Age. The vegetation on southern Prince of Wales Island underwent marked transitions during the Little Ice Age and Medieval Climate Anomaly, which was mainly observed in the proportion of Cyperaceae and Poaceae. The mean July temperature reconstruction showed a long-term cooling from 1080-1915 CE with a sustained cold period from 1800-1915 CE prior to 20th-century warming. A synthesis of paleoclimate records from across the Arctic demonstrated that pollen-based reconstructions record both high and low frequency climate variability, when sampling resolution is sufficient, and can improve regional climate reconstructions.

description: A very high efficient, low distortion C-band power amplifier using a linear and non-linear models of the PHEMT devices has been developed. Single stage amplifier fabricated with 4x18mm gate width PHEMT devices exhibits a power output of 44 dBm at 2dB of gain compression, a linear gain of 11.5dB and an associated PAE from 50% to 52% in the frequency range of 3.6-3.9GHz. These excellent results are performed by developing an accurate non-linear model of the PHEMT device, the 2.5D electromagnetic simulation of the passive structures and optimizing the output matching network of the amplifier by using a high dielectric substrate with low insertion loss.

An extensive experimental device characterisation, together with numerical simulations using suitable non-linear transistor models is carried out. Experimental data were compared with different transistor models in order to understand the effect of the various cell parameters on the device IMD3 response. The data collected were applied in the design of a highly linear power amplifier family, covering different frequency ranges.

description: This dissertation explores informal means of convening various foreign policy professionals in conflict resolution discussions, taking two quite different case studies: the Pugwash Conferences, a long-standing transnational non-governmental organization; and the Ottawa Dialogue, a more recent suite of projects. Although conventionally viewed through the rubric of ‘Track Two’, this thesis instead tackles the subject of unofficial diplomacy through a conceptual framework derived from critical and sociological work in International Relations theory. By taking a practice-based approach, the research reveals that what is actually done in the spaces of unofficial diplomacy not only has a diplomatic purpose at root but in fact can be seen to reproduce a diplomatic logic in how certain tasks are performed. The dissertation shows the intrinsic liminality of these informal, unofficial activities to the corridors of power and policymaking and, in this way, helps elaborate how the emergent landscape of diplomacy is impacted by various actors and changing practices. To understand why such processes appear around international conflict, the thesis calls attention to investigating how they are used by those who participate. The approach brings into focus the constitution of professional social networks that emerge in spaces left out of limelight, where various experts contest, debate, and refract policy knowledge. Through the eyes of these non-traditional actors, the thesis problematizes diplomacy as a solely state-based authority, insisting that we must look to the close imbrication of government representatives in putatively non-state activities to understand their contribution to global governance. Developed through an immersion and engagement of ten years with the very people who do the work, this project brings together several theoretical and methodological perspectives to make sense of a complex data-set and bridge a number of disciplinary gaps.

description: What is the dimension of a smooth family of complex Hadamard matrices including the Fourier matrix? We address this problem with a power series expansion. Studying all dimensions up to 100 we find that the first order result is misleading unless the dimension is 6, or a power of a prime. In general the answer depends critically on the prime number decomposition of the dimension. Our results suggest that a general theory is possible. We discuss the case of dimension 12 in detail, and argue that the solution consists of two 13-dimensional families intersecting in a previously known 9-dimensional family. A precise conjecture for all dimensions equal to a prime times another prime squared is formulated.

description: A general master equation is derived to describe an electromechanical single-dot transistor in the Coulomb blockade regime. In the equation, Fermi distribution functions in the two leads are taken into account, which allows one to study the system as a function of bias voltage and temperature of the leads. Furthermore, we treat the coherent interaction mechanism between electron tunneling events and the dynamics of excited vibrational modes. Stationary solutions of the equation are numerically calculated. We show current through the oscillating island at low temperature appears step like characteristics as a function of the bias voltage and the steps depend on mean phonon number of the oscillator. At higher temperatures the current steps would disappear and this event is accompanied by the emergence of thermal noise of the charge transfer. When the system is mainly in the ground state, zero frequency Fano factor of current manifests sub-Poissonian noise and when the system is partially driven into its excited states it exhibits super-Poissonian noise. The difference in the current noise would almost be removed for the situation in which the dissipation rate of the oscillator is much larger than the bare tunneling rates of electrons.

description: Das Diffusionsverhalten von Alkoholen und deuterierten Alkoholen wurde in den Lösungsmitteln Toluol und Tetrachlorkohlenstoff untersucht. Die Diffusionsgeschwindigkeiten wurden für die binären Systeme der unassoziierten Alkohole und für die ternären, ein tertiäres Amin als Protonenakzeptor enthaltenen, Systeme bestimmt. Die Untersuchungen wurden in einer von Anderson beschriebenen Kapillarzelle durchgeführt. Die Ergebnisse können als eine lineare Abhängigkeit zwischen der Diffusionsgeschwindigkeit und der Acidität des OH-Protons, sowie der Basizität der tertiären Amine. Andere Zusammenhänge wurden zwischen der Wechselwirkungsstärke zwischen Alkohol und Lösungsmittel und sterischen Effekten festgestellt. Offensichtlich bewirkt ein Ansteigen der Gleichgewichtskonstanten und der Assoziationsenthalpien der gebildeten wasserstoffverbrückten Komplexe eine signifikante Erhöhung der Diffusionsgeschwindigkeiten der untersuchten Alkohole.
description: The diffusion behaviour of alcohols and deuteriated alcohols was investigated in toluene and tetrachlorocarbon as solvents. The diffusion rates of the alcohols were determined for the binary systems of the unassociated alcohols and in the ternary systems in which tertiary amines were added as hydrogen bond partners. The experiments were performed in a capillary cell, described by Anderson. The results may be expressed in linear correlations between the diffusion rate and the acidity of the OH proton, as well as the basicities of the tertiary amines. Other correlations are determined by the strength of the solute-solvent interactions and the sterical effects. Evidently increasing equilibrium constants and increasing association enthalpies of the hydrogen bonded complexes enlarge the diffusion rate of the alcohols significantly.

description: In this paper, a new defected ground structure (DGS) λ /4 bias line that dumbbell-shaped ground pattern is etched on ground plane of microstrip line is proposed. This DGS λ /4 bias line maintains high impedance, but physical width is wider and length is shorter than that of the conventional bias line. If the proposed bias line is attached on signal transmission line, this bias line can reduces the 3 rd harmonic signal as well as the 2 nd harmonic signal. With harmonic reduction characteristics, efficiency and linearity of amplifier are improved. When the proposed bias line is adopted in power amplifier on IMT-2000 basestation transmitting band, the 3 rd harmonic signal is reduced about 26.5dB and efficiency is improved about 9.1% and IMD3 is improved 4.5dB than the conventional structure.

description: A novel adaptive design for feedforward amplifier linearizer with analog controller is proposed in this paper. Compared previous adaptive linearizing method, this is new design which does not require any pilot signal and intentional signal distortion. In main signal cancellation loop, magnitude and phase of two-path signal in subtracter are compared mutually and controlled for main signal cancellation. In distortion signal cancellation loop, gain and phase of each path is controlled to maintain constant, so that the same level and out-of phase of two-path distortion signal are obtained. A prototype feedforward amplifier with the proposed linearizer has been tested for 3-carrier IS-95 CDMA signals and 20.25dB ACPR is improved.

Bi-local Construction of Sp(2N)/dS Higher Spin Correspondence

description: We derive a collective field theory of the singlet sector of the Sp(2N) sigma model. Interestingly the hamiltonian for the bilocal collective field is the same as that of the O(N) model. However, the large-N saddle points of the two models differ by a sign. This leads to a fluctuation hamiltonian with a negative quadratic term and alternating signs in the nonlinear terms which correctly reproduces the correlation functions of the singlet sector. Assuming the validity of the connection between O(N) collective fields and higher spin fields in AdS, we argue that a natural interpretation of this theory is by a double analytic continuation, leading to the dS/CFT correspondence proposed by Anninos, Hartman and Strominger. The bi-local construction gives a map into the bulk of de Sitter space-time. Its geometric pseudospin-representation provides a framework for quantization and definition of the Hilbert space. We argue that this is consistent with finite N grassmanian constraints, establishing the bi-local representation as a nonperturbative framework for quantization of Higher Spin Gravity in de Sitter space.

description: Linearity and efficiency of AlGaN/GaN MODFETs were investigated under large-signal conditions. The power-added-efficiency (PAE) of 0.25´ 200 mm 2 devices was found to be ~33% and ~45 % without and with harmonic tuning. Third-order Intermodulation (IMD3) was also measured using the two-tone technique. Third-order Intercept Point (IP3) of ~ 29 dBm at Pin= 15 dBm was obtained at f0= 5 GHz (Df= 10 MHz). Load-pull contours showed that thempedance values for best PAE and Pout are very close. IP3 was found to be insensitive to the gate bias voltage. In addition, high efficiency and high linearity can be achieved simultaneously with the assistance of harmonic termination.

description: A computationally efficient procedure for the design of RF power amplifiers is presented. The proposed approach allows for the identification of “near-optimal” source and load terminations of the amplifier stage providing maximum output power under assigned linearity, minimum gain and other possible constraints. The design procedure is completely based on closed form numerical computations, without requiring non linear optimisations as normally happens in standard design approaches. A single-stage 2.4 GHz amplifier prototype has been designed and manufactured in Silicon BJT MMIC technology, according to the criteria provided by the new methodology. Experimental results are in good agreement with simulations and confirm the validity of the proposed approach.

Determination of protein requirements of healthy pregnant women during early and late gestation using the indicator amino acid oxidation technique
Creators: name: Stephens, Trina
Publisher: name: University of British Columbia
Year: 2013

description: Adequate maternal dietary protein (PRO) intake is necessary to support rapid tissue accretion during a healthy pregnancy. Both insufficient and excessive maternal PRO intake during pregnancy is associated with intrauterine growth restriction (IUGR) of the fetus. IUGR increases the risk of neonatal morbidity and mortality, and is associated with an increased risk of future health problems, including cardiovascular disease, kidney disease, obstructive airway disease, and obesity. However, current PRO intake recommendations for healthy pregnant women are based on factorial calculations of nitrogen balance data derived from non-pregnant adults. Thus, an estimate of PRO requirements based on pregnancy-specific data is needed. PRO requirements of healthy pregnant women at 11-20 (early) and 31-38 (late) weeks gestation were determined using the indicator amino acid oxidation (IAAO) method. Twenty-nine healthy women (age 24-37) each randomly received a different test PRO intake (range = 0.22-2.56 g/kg/day) during each study day in early (n=37) and late (n=44) gestation. The diets were isocaloric and provided energy at 1.7 X resting energy expenditure (REE). PRO was given as a crystalline amino acid mixture based on egg PRO composition, except phenylalanine and tyrosine, which were maintained constant across intakes. PRO requirements were determined by measuring the oxidation of L-[1-¹³C]phenylalanine to ¹³CO₂ (F¹³CO₂). Breath and urine samples were collected at baseline and isotopic steady state. Linear regression crossover analysis identified a breakpoint (requirement) at minimal F¹³CO₂ in response to different PRO intakes. The estimated average requirement (EAR) for PRO in early and late gestation was determined to be 1.22 and 1.52 g/kg/d, respectively. Both of these estimates are significantly greater than the EAR of 0.88 g/kg/d currently recommended by the Dietary Reference Intakes (DRI 2005). Our results indicate increased demand for PRO before 20 weeks gestation (on a gram per kilogram body weight basis), a consideration that has not been addressed by current DRI recommendations. This study is the first to directly estimate gestational PRO requirements in a population composed solely of healthy pregnant women, and suggests that current recommendations based on the nitrogen balance method and factorial calculations underestimate PRO requirements.
