description: Lüscher established a non-perturbative formula to extract the elastic scattering phases from two-particle energy spectrum in a torus using lattice simulations. Rummukainen and Gottlieb further extend it to the moving frame, which is devoted to the system of two identical particles. In this work, we generalize Rummukainen-Gottlieb's formula to the generic two-particle system where two particles are explicitly distinguishable, namely, the masses of the two particles are different. The finite size formula are achieved for both $C_{4v}$ and $C_{2v}$ symmetries. Our analytical results will be very helpful for the study of some resonances, such as kappa, vector kaon, and so on.

description: This paper presents a chip set operating at 3 V supply voltage for cellular communications at L-band. A high efficiency power amplifier with a high packing density is reported. It makes use of high power-added-efficiency of MESFET devices in saturated class AB, and harmonic enhancement for the matching circuits. This three stage MMIC amplifier delivers 27 dBm output power with 35 % of power added efficiency with 0 dBm input power. A power switch is also described which achieves a typical insertion loss in the (0.8 dB, 1.0 dB) range and performs 20 dB isolation between the Rx (Receive) and Tx (Transmit) chains. PML also proposes a power MESFET that achieves 33 dBm output power with 55 % drain efficiency and 6 dB associated gain at 1800 MHz.

description: Several MMIC downconverters have been developed for use in experimental 30/20 GHz Satellite Personal Communications Terminals. The non-linear PHEMT and diode models are described and the design and performance of the downconverters are discussed. The design and performance a 30 GHz single-balanced PHEMT diode upconverter is also reported. The 20/4 GHz downconverter has a conversion loss of 1.5 dB at 20 GHz while the 30/4 GHz version was found to have 3.0 dB loss at 30 GHz. Both mixers showed spurious suppression better than 40 dB and required 3.5 dBm of LO power. The DC-50 MHz/30 GHz single balanced PHEMT diode upconverter, using a miniature distributed 180° hybrid, was found to have 10 dB conversion loss between 10 and 50 MHz. The RF-LO isolation was 22 dB.

description: This thesis explores the intricate mechanisms governing paracellular permeability, a process vital for maintaining homeostasis and barrier integrity in epithelial and endothelial tissues. Central to this exploration are tight junctions (TJs), multi-protein complexes that regulate substance movement between cells. The thesis begins with a comprehensive literature review synthesizing current research on how bacterial and viral proteins can enhance paracellular permeability or modulate TJs, highlighting their significance in both scientific and medical fields.A focal point of the thesis is the detailed study of the Listeria adhesion protein (LAP), an epithelial TJ modulator (TJM). LAP’s interaction with the epithelial receptor, Hsp60, facilitates the translocation of Listeria monocytogenes across the epithelial barrier, presenting a novel approach for drug delivery. Addressing the limitations of current TJMs, such as poor bioavailability and toxic side effects, the thesis provides an in-depth analysis of LAP as an alternative biologics’ delivery vehicle. Utilizing a multidisciplinary research approach, the study reveals the cryo-EM structure of LAP at 2.9 Å resolution, elucidating its multimeric formation and interaction with Hsp60 through electrostatic forces, as supported by computational modeling.The functional efficacy of LAP is further established through experiments demonstrating its capability to transport drug analogs across epithelial cell monolayers comparably to established TJMs. Moreover, in vivo studies using a mouse oral gavage model show that LAP significantly enhances the blood levels of peptide drugs without triggering inflammatory responses or harming tight junction architecture. This thesis ultimately positions the LAP-Hsp60 complex as a promising TJM candidate, offering an innovative means for enhancing oral drug delivery and maintaining epithelial barrier integrity.

description: We report quantum dots fabricated on very shallow 2-dimensional electron gases, only 30 nm below the surface, in undoped GaAs/AlGaAs heterostructures grown by molecular beam epitaxy. Due to the absence of dopants, an improvement of more than one order of magnitude in mobility (at 2E11 /cm^2) with respect to doped heterostructures with similar depths is observed. These undoped wafers can easily be gated with surface metallic gates patterned by e-beam lithography, as demonstrated here from single-level transport through a quantum dot showing large charging energies (up to 1.75 meV) and excited state energies (up to 0.5 meV).

description: We extend our earlier study of special double limits of `boosted' $AdS_5$ black hole solutions to include all black D$p$-branes of type II strings. We find that Lifshitz solutions can be obtained in generality, with varied dynamical exponents, by employing these limits. We then study such double limits for `boosted' D$p$-brane bubble solutions and find that the resulting non-relativistic solutions instead describe Schrödinger like spacetimes, having varied dynamical exponents. We get a simple map between these Lifshitz & Schrödinger solutions and a relationship between two types of dynamical exponents. We also discuss about the singularities of the Lifshitz solutions and an intriguing thermodynamic duality.

Energy Minimization for the Half-Duplex Relay Channel with Decode-Forward Relaying

description: We analyze coding for energy efficiency in relay channels at a fixed source rate. We first propose a half-duplex decode-forward coding scheme for the Gaussian relay channel. We then derive three optimal sets of power allocation, which respectively minimize the network, the relay and the source energy consumption. These optimal power allocations are given in closed-form, which have so far remained implicit for maximum-rate schemes. Moreover, analysis shows that minimizing the network energy consumption at a given rate is not equivalent to maximizing the rate given energy, since it only covers part of all rates achievable by decode-forward. We thus combine the optimized schemes for network and relay energy consumptions into a generalized one, which then covers all achievable rates. This generalized scheme is not only energy-optimal for the desired source rate but also rate-optimal for the consumed energy. The results also give a detailed understanding of the power consumption regimes and allow a comprehensive description of the optimal message coding and resource allocation for each desired source rate and channel realization. Finally, we simulate the proposed schemes in a realistic environment, considering path-loss and shadowing as modelled in the 3GPP standard. Significant energy gain can be obtained over both direct and two-hop transmissions, particularly when the source is far from relay and destination.

Using forest structure to model vertical variations of canopy radiation and productivity
Creators: name: Van Leeuwen, Martin
Publisher: name: University of British Columbia
Year: 2014

description: The productivity of autotrophic organisms affects all life on Earth; hence, gaining insight in the variability of autotrophic productivity has received significant research interest. At cell to organism level, much knowledge has been gained under controlled conditions through laboratory analysis. At the stand level and beyond, control over the driving variables is limited, and hence experiments have relied on extensive time series, and geospatial analysis to observe changes in productivity across a wide range of environmental conditions. Significant technologies at these scales are eddy covariance that provides point sample estimates of productivity by measuring CO₂ fluxes between land and atmosphere, and remote sensing that provides for extrapolating eddy-covariance measurements across the landscape using canopy-reflectance data. Challenges in fusing eddy covariance with remote sensing relate to the limited capacity of airborne and spaceborne instruments to observe changes in the biophysical state of deep canopy strata; hence, eddy-covariance estimates that capture the productivity of an arbitrarily dense canopy volume are extrapolated based on top-of-canopy reflectance data. Proximal-sensing technology extends the acquisition of reflectance data to arbitrary locations within the canopy; however, these data are affected by the immediate canopy structure surrounding the sensor that introduces a sensor-location bias, and the direct use of these data in stand-level models is therefore challenging. This thesis explores the simulation of photosynthetic down-regulation using geometrically explicit forest models and meteorological records. The geometrically explicit models are constructed by combining laser-scanning data with tree-regeneration models, and are used to simulate a time series of leaf-level incident radiation. The parameters of a leaf-level photosynthesis model are then optimized against eddy-covariance productivity estimates. Finally, the potential of geometrically explicit models for the fusion of remote sensing and proximal sensing data is discussed.

description: The record statistics of complex random states are analytically calculated, and shown that the probability of a record intensity is a Bernoulli process. The correlation due to normalization leads to a probability distribution of the records that is non-universal but tends to the Gumbel distribution asymptotically. The quantum standard map is used to study these statistics for the effect of correlations apart from normalization. It is seen that in the mixed phase space regime the number of intensity records is a power law in the dimensionality of the state as opposed to the logarithmic growth for random states.

We also construct such examples in a smaller Schrödinger class.

Reciprocal regulation of glutamine metabolism and reactive oxygen species
Creators: name: Cetinbas, Naniye
Publisher: name: University of British Columbia
Year: 2015

description: Reactive oxygen species (ROS) are byproducts of normal cellular processes. While low or moderate levels of ROS promote and sustain oncogenic properties of cancer cells, excessive amounts are detrimental. Cancer cells counterbalance increased ROS production by engaging ROS-scavenging systems, which heavily rely on the antioxidants GSH and NADPH that can be synthesized from glutamine (GLN). Although GLN is not an essential amino acid, some cancer cells depend on exogenous GLN for survival, a phenotype known as GLN addiction. GLN plays versatile roles in cells from synthesis of macromolecules to redox balance. However, why GLN dependence for survival varies among different cancer cell types is not fully understood. This thesis tested the hypothesis that GLN addiction phenotype is ROS dependent. We first showed that loss of Hace1, a tumor suppressor that regulates ROS levels, results in increased GLN metabolism and GLN addiction. Inhibition of ROS reverses GLN addiction phenotype of Hace1 deficient cells, providing the first evidence that loss of a tumor suppressor leads to GLN addiction due to increased ROS levels. Using a panel of human cancer cell lines we established that GLN deprivation induces cell death in GLN addicted cells primarily by depleting intracellular antioxidant pools, resulting in increased ROS levels and oxidative damage. Furthermore GLN deprivation results in ROS-dependent elevation of glucose uptake in GLN addicted cells, which exacerbates oxidative stress causing cell death. Finally, we showed that GLN addicted cells are more sensitive to exogenous oxidants without GLN, and that AMPK mediated upregulation of ASCT2 expression and GLN uptake confers resistance to oxidative stress in GLN addicted cells. These studies establish the reciprocal regulation of GLN metabolism and oxidative stress in cancer cells.

description: Sparsity-constrained optimization has wide applicability in machine learning, statistics, and signal processing problems such as feature selection and compressive Sensing. A vast body of work has studied the sparsity-constrained optimization from theoretical, algorithmic, and application aspects in the context of sparse estimation in linear models where the fidelity of the estimate is measured by the squared error. In contrast, relatively less effort has been made in the study of sparsity-constrained optimization in cases where nonlinear models are involved or the cost function is not quadratic. In this paper we propose a greedy algorithm, Gradient Support Pursuit (GraSP), to approximate sparse minima of cost functions of arbitrary form. Should a cost function have a Stable Restricted Hessian (SRH) or a Stable Restricted Linearization (SRL), both of which are introduced in this paper, our algorithm is guaranteed to produce a sparse vector within a bounded distance from the true sparse optimum. Our approach generalizes known results for quadratic cost functions that arise in sparse linear regression and Compressive Sensing. We also evaluate the performance of GraSP through numerical simulations on synthetic data, where the algorithm is employed for sparse logistic regression with and without $\ell_2$-regularization.

description: Histone acetylation is a specific type of chromatin modification that serves as a key regulatory mechanism for many cellular processes in mammals. However, little is known about its biological function in invertebrates. Here, we identified 12 members of histone deacetylases (NlHDACs) in the brown planthopper (BPH), Nilaparvata lugens. RNAi-mediated silencing assay showed that NlHdac1, NlHdac3 and NlHdac4 played critical roles in female fertility via regulating ovary maturation or ovipositor development. Silencing of NlHdac1 substantially increased acetylation level of histones H3 and H4 in ovaries, indicating NlHDAC1 is the main histone deacetylase in ovaries of BPH. RNA sequencing (RNA-seq) analysis showed that knockdown of NlHdac1 impaired ovary development via multiple signalling pathways including the TOR pathway. Acoustic recording showed that males with NlHdac1 knockdown failed to make courtship songs, and thus were unacceptable to wild-type females, resulting in unfertilized eggs. Competition mating assay showed that wild-type females overwhelmingly preferred to mate with control males over NlHdac1-knockdown males. These findings improve our understanding of reproductive strategies controlled by HDACs in insects and provide a potential target for pest control.

That is, starting from an algebra equipped with an automorphism, two twisted derivations, and a twisted invariant trace, we construct an algebra of formal twisted pseudodifferential symbols and define a noncommutative residue. Also, we provide related examples.

To investigate the stability of homogeneous stationary states of this generalized model, we consider the eigenvalues of a linearized system. We are able to reduce this infinite dimensional eigenproblem to a parametrized finite dimensional eigenproblem. By matrix theoretic tools, we then provide easily verifiable sufficient conditions for destabilizing the homogeneous stationary states. In particular, one of the sufficient conditions is that the chemotactic feedback is sufficiently strong. Although this mechanism was already known to exist in the original Keller-Segel model, here we show that it is more generally applicable by significantly enlarging the class of models exhibiting this instability phenomenon which may lead to pattern formation.

description: Ziel dieser Arbeit war es, die Nichtwirtsresistenz (NHR) von Arabidopsis thaliana gegen Phytophthora infestans mit Fokus auf der induzierten Akkumulation von Sekundärmetaboliten an der Zellperipherie zu untersuchen und zu charakterisieren. Die bekannten A. thaliana Mutantenlinien pen2 und pen3, auf denen P. infestans öfter in der Lage ist erfolgreich die Epidermis zu penetrieren, wurden dafür hinzugezogen. PEN2 und PEN3 werden in Abbau- und Transportprozesse von Tryptophan abhängigen Indolglucosinolaten und deren Abbauprodukten eingeordnet. Als mögliche Abbauprodukte wurden 4-Methoxyindol-3-methanol und 4-Methoxyindol-3-methylcystein als PEN2 und PEN3-abhängige Sekundärmetaboliten identifiziert, die nach Inokulation mit P. infestans extrazellulär akkumulieren. Eine antimikrobielle Wirkung in vitro wurde für diese Sekundärmetaboliten nicht festgestellt. 4-MeOI3M aber nicht 4-MeOI3Cys löst eine intrazelluläre Erhöhung der Ca2+ Ionen Konzentration aus und trägt zur flg22-induzierten Calloseablagerung in A. thaliana Keimlingen bei, was ein Hinweis auf eine Wirkung als Signalsubstanz oder Modulator der Abwehr sein könnte.
description: To analyze and characterize the nonhost resistance (NHR) of Arabidopsis thaliana against Phytophthora infestans with focus on the induced accumulation of secondary metabolites at the cell periphery was the main goal of this work. The A. thaliana mutant lines pen2 and pen3 which allow P. infestans more often to penetrate successfully were analyzed for this purpose. PEN2 and PEN3 are components of synthesis and transport processes of tryptophan derived secondary metabolites like indoleglucosinolates. Possible breakdown products of those substances were identified as 4-Methoxyindole-3-methanol and 4-Methoxyindole-3-methylcysteine which accumulate on the surface of inoculated leaf material in a PEN2 and PEN3 dependent manner. Antimicrobial activity could not be observed for both compounds in vitro. 4-MeOI3M but not 4-MeOI3Cys induces an intracellular increase of Ca2+ ion concentration and contribute to the flg22 induced callose depositions in A. thaliana seedlings which may be a evidence for a signaling or modulating function in defense responses.

description: We analyze electromagnetic field propagation through a random medium which consists of hyperbolic metamaterial domains separated by regions of normal "elliptic" space. This situation may occur in a problem as common as 9 micrometer light propagation through a pile of sand, or as exotic as electromagnetic field behavior in the early universe immediately after the electro-weak phase transition. We demonstrate that spatial field distributions in random hyperbolic and random "elliptic" media look strikingly different. This effect may potentially be used to evaluate the magnitude of magnetic fields which existed in the early universe.

description: The Laser Interferometer Gravitational-Wave Observatory forms part of the international effort to detect and study gravitational waves of astrophysical origin. One of the major obstacles for this project with the first generation detectors was the effect of seismic noise on instrument sensitivity - environmental disturbances causing motion of the interferometer optics, coupling as noise in the gravitational wave data output. Typically transient noise events have been identified by finding coincidence between noise in an auxiliary data signal (with negligible sensitivity to gravitational waves) and noise in the gravitational wave data, but attempts to include seismometer readings in this scheme have proven ineffective. We present a new method of generating a list of times of high seismic noise by tuning a gravitational wave burst detection pipeline to the low frequency signature of these events. This method has proven very effective at removing transients of seismic origin from the gravitational wave (GW) data with only a small loss of analysable time. We also present an outline for extending this method to other noise sources.

description: Vor dem Schlachten müssen die Puten transportiert werden, wobei sie durch das herausnehmen aus der gewohnten Umgebung, Unterbrechung der Futteraufnahme und den Transport verschiedenen Belastungen ausgesetzt sind. Die Ergebnisse dieser Untersuchung zeigen, dass die Transportentfernung einen deutlich geringeren Einfluss auf den Glykolyseverlauf ausübt als die Gesamtaufenthaltszeit der Puten in den Käfigen. Nüchterungszeiten der Puter über 13 Stunden hinaus sollten vermieden werden, da durch die Verminderung der Glykogen-Reserven im Brustmuskel ein höherer End-pH-Wert dieses Teilstücks begünstigt wird. Für eine Fleischqualitätssortierung in den Schlacht- und Verarbeitungsbetrieben würden sich besonders der pH-Wert 20 min p.m. sowie der Leitfähigkeitswert 24 h nach dem Schlachten eignen. Beide Messwerte zeigen deutliche Zusammenhänge zu den Qualitätsparametern Saftigkeit, Zartheit, Kochverlust und Scherkraft. Somit könnten die Betriebe eine Klassifizierung der Tiere sowohl in der Schlachtkette durch die Messung des pH20-Wertes als auch am gekühlten Schlachtkörper anhand der LF-Messung durchführen. Eine Qualitätseinstufung auf Grund der Farbe des Putenfleisches (L*-Wertes) kann anhand der eigenen Untersuchung nicht empfohlen werden.
description: Prior to slaughter turkey are exposed to stress because of removal from their familiar environment, deprivation from food and transport itself. The results of this investigation indicate that transport distance influences the rate of glycolysis less compared to the total duration of the turkey’s stay in the transport cages. Food withdrawals for more than thirteen hours before slaughter should be avoided since the reduced glycogen reserves in the breast muscle favour higher final pH-values in that retail chop. Both the pH-value 20 min post mortem and the electrical conductivity 24 hours after slaughter show distinct interrelations to sensory traits, e.g. juiciness, tenderness, cooking loss and shear value. Especially those parameters thus enable commercial packing plants to classify turkey meat immediately after slaughter as well as on chilled carcasses. Concluding from the results of the current investigation, a classification of turkey meat quality only based on its colour (L-value) cannot be recommended.
Novel concepts in MMIC design

description: This paper is a plea for more Imaginative design of MMIC circuits. A survey of architectural development of MMIC circuit design will be given starting from initial extrapolations from Hybrid designs but using lumped rather than distributed components. After this the use of distributed-feed networks gave new possibilities for wide-band applications. Finally a logical extension is proposed for new architectures which could reach out to the KW chip, or the 16-bit Phase shifter. This is a super-modular approach for low cost, close packing density, improved reliability and faster testing. Examples for Amplifiers and Phase-shifters will illustrate the novel aspects of this approach. This evolution has been made possible because of the improvements in production precision and reproducability, and also to the accurate design tools that are available today in this technology. There are now many possibilities for imaginative design of MMIC circuits with new design principles which were hitherto unrealistic. It is hoped that these reflexions will provoke new thoughts on basic MMIC design principles.

description: It is shown for a spherically symmetric black hole of general type that it is impossible to observe the infinite future of the Universe external to the hole during the finite proper time interval of the free fall. Quantitative evaluations of the effect of time dilatation for circular orbits around the Kerr black hole are obtained and it is shown that the effect is essential for ultrarelativistic energies of the rotating particle.
