description: Three Cu(II) complexes, Cu2(bpy)(H2O)(Clma)2 (1), Cu2(bpe)(H2O)2(Clma)2 (2), and Cu(bpp)(Clma) (3), were synthesized (HClma = (R)-2-Chloromandelic acid, bpy = 4,4′-dipyridine, bpe = 1,2-di(4-pyridyl)ethylene, bpp = 1,3-di(4-pyridyl)propane). Complexes 1, 2, and 3 are constructed from 1-D coordination arrays generated from Cu2(H2O)(Clma)2, Cu2(H2O)2(Clma)2, and Cu2(Clma)2 moieties and linked through bpy, bpe, and bpp co-ligands, respectively. 1 and 2 are assembled into 3-D supramolecular networks via O–H⋯O hydrogen bonds with topology of (63)(69·8) and (412·63), respectively, and 3 is assembled into a 3-D architecture through C–H⋯O hydrogen bonds with topology of (43·63)(43)(44·65·8)(46·66·83). Compounds 1, 2, and 3 crystallized in acentric space groups P21, P1, and P21, which exhibit significant ferroelectricity (remnant polarization Pr = 0.008 μC cm−2, coercive field Ec = 21.4 kV cm−1, the spontaneous saturation polarization Ps = 0.167 μC cm−2 for 1, Pr = 0.183 μC cm−2, Ec = 1.69 kV cm−1, and Ps = 0.021 μC cm−2 for 3). Results from infrared and thermal analyses are also discussed.

description: We introduce a novel scheme that combines phonon-mediated quantum logic gates in trapped ions with the benefits of continuous dynamical decoupling. We demonstrate theoretically that a strong driving of the qubit decouples it from external magnetic-field noise, enhancing the fidelity of two-qubit quantum gates. Moreover, the scheme does not require ground-state cooling, and is inherently robust to undesired ac-Stark shifts. The underlying mechanism can be extended to a variety of other systems where a strong driving protects the quantum coherence of the qubits without compromising the two-qubit couplings.

description: The angular momentum density and flux of light in a dispersive, rotationally symmetric medium are derived from Noether's theorem. Optical angular momentum in a dispersive medium has no simple relation to optical linear momentum, even if the medium is homogeneous. A circularly polarized monochromatic beam in a homogeneous, dispersive medium carries a spin angular momentum of $\pm\hbar$ per energy $\hbarω$, as in vacuum. This result demonstrates the non-trivial interplay of dispersive contributions to optical angular momentum and energy.

description: Studienziel: Vergleichende Untersuchung der funktionalen sowie laborchemischen Ergebnisse nach endoprothetischem Kniegelenksersatz über den standardisierten bzw. den minimalinvasiven Midvastus-Zugang. Methode: Im Rahmen der prospektiven randomisierten Studie erfolgte der endoprothetische Kniegelenksersatz bei je 30 Patienten über den standardisierten (Standard-Gruppe), bzw. minimal-invasiven Midvastus-Zugang. Es wurden der Knee-Society-Score (KSS), der Stolzalpe-Activity-Score und die visuelle Analogskala, Myoglobin- und Creatininwerte sowie der intra-und postoperative Blutverlust bis zu zwölf Wochen postoperativ untersucht. Die Positionierungder Implantate wurde mit dem Knee Society Roentgenographic Evaluation and Scoring System bestimmt. Ergebnisse: Die Ergebnisse des KSS und Activity Scores zeigen bis zu 12 Wochen postoperativ Vorteile für die Patienten der MIS-Gruppe. Der postoperative Anstieg von Myoglobin und Creatininkinase ist bis zu 24 h bzw. 72 h in der MIS- Gruppe geringer. Unterschiede im Blutverlust und der Implantatpositionierung bestanden nicht. Schlussfolgerung: Die minimalinvasive Technik am Kniegelenk führt durch die Minimierung des Weichteiltraumas zu verbesserten klinisch-funktionellen Ergebnissen in der frühen postoperativen Phase ohne die sichere Implantatpositionierung zu gefährden.
description: Aim: The aim of this prospective randomised study is to compare the results after TKA using an MIS approach versus a standard approach. Methods: We compared 30 TKA using a mini-midvastus approach (MIS group) with 30 conventionelly performed TKA using a midvastus approach (control group). The Knee Society score (KSS), an activity score, the visual analogue scale, myoglobin and creatinine kinase as well as the blood loss were measured up to 12 weeks after surgery. Implant positioning was evaluated using the Knee Society Roentgenographic evaluation and scoring system. Results: Advantages of the MIS group were measured in KSS and activity score up to 12 weeks after surgery. The increase of myoglobin and creatinine kinase was lower in the MIS group up to 24 hours or 72 hours, respectively. No differences were found comparing the implant positioning and blood loss. Conclusion: The MIS technique in TKA with minimisation of the soft tissue trauma leads to better clinical and functional results in the early postoperative time and does not modify the implant positioning.

description: We propose in this paper an integrated cavity-backed horn antenna, generalizing the well-known SSFIP (Strip-Slot-Foam-Inverted Patch) design, operating at 75 GHz. The antenna was optimized using a full-wave software and realized using micromachining technologies. The proposed structure can be used for high radiation ef-ficiency antennas and arrays in the millimeter-wave band, since surface waves are inherently suppressed by the use of a metallic horn and a cavity configuration.
An investigation into the role of C-terminal tensin-like protein (Cten) in melanomagenesis
Creators: name: Sjoestroem, Anna Cecilia
Publisher: name: University of British Columbia
Year: 2013

description: C-terminal tensin-like protein (Cten) is a focal adhesion protein with no or limited protein expression in normal tissues, which has recently been reported to be overexpressed and act as an oncoprotein in numerous cancers. Since its expression status in human cutaneous melanoma is currently unknown, I used tissue microarrays and immunohistochemical staining to examine the protein expression of Cten throughout melanoma progression. I found that Cten was significantly up-regulated in dysplastic nevi (DN) compared to normal nevi (NN), and in primary melanoma (PM) compared to both DN and NN. Strong Cten staining was associated with a poorer 5- and 10-year overall and disease-specific survival for PM patients, and was an adverse independent prognostic factor for the 5-year survival of the same patients. In vitro studies using two melanoma cell lines supported these findings and indicated that Cten functions as an oncogene in melanoma. Since relatively little is known about how Cten contributes to tumorigenesis, I next investigated the expression profile of the RhoGAP Deleted in Liver Cancer-1 (DLC1), the only protein known to bind to Cten, in melanomas. Both cytoplasmic and nuclear DLC1 were detected, and both were down-regulated in metastatic melanoma (MM) compared to PM and nevi, with nuclear DLC1 expression additionally being reduced in PM compared to nevi. Both cytoplasmic and nuclear DLC1 were associated with the 5-year overall and disease-specific survival of all melanoma and MM patients, and with the disease-specific 10-year survival of all melanoma patients. Combined analysis of cytoplasmic and nuclear DLC1 revealed that for MM patients, concurrent loss of both cytoplasmic and nuclear DLC1 was associated with the worst survival outcome, with loss of either or both forms being a significant adverse independent prognostic factor for the 5-year survival of all melanoma and MM patients. A preliminary investigation into the relationship between Cten and DLC1 indicated that the effects of Cten on patient survival were dependent on the levels of DLC1, as expected. In summary, I here provide an initial characterization of the expression status and role of Cten in melanomagenesis, and speculate that it functions partly via interactions with the tumour suppressor DLC1.

description: We investigate the observational consequences of the quintessence field rolling to and oscillating near a minimum in its potential, "if" it happens close to the present epoch (z<0.2). We show that in a class of models, the oscillations lead to a rapid growth of the field fluctuations and the gravitational potential on subhorizon scales. The growth in the gravitational potential occurs on timescales << H^(1). This effect is present even when the quintessence parameters are chosen to reproduce an expansion history consistent with observations. For linearized fluctuations, we find that although the gravitational potential power spectrum is enhanced in a scale-dependent manner, the shape of the dark matter/galaxy power spectrum is not significantly affected. We find that the best constraints on such a transition in the quintessence field is provided via the integrated Sachs-Wolfe (ISW) effect in the CMB temperature power spectrum. Going beyond the linearized regime, the quintessence field can fragment into large, localized, long lived excitations (oscillons) with sizes comparable to galaxy clusters; this fragmentation could provide additional observational constraints. Two quoted "signatures" of modified gravity are a scale-dependent growth of the gravitational potential and a difference between the matter power spectrum inferred from measurements of lensing and galaxy clustering. Here, both effects are achieved by a minimally coupled scalar field in general relativity with a canonical kinetic term.

description: The general study is dedicated to Wireless Sensor Networks. The idea is to associate micro-mechanical and microwave communication functions to exchange information between a remote sensor and a base station [1]. A specific part of this project concerns the conception, realisation, and characterisation of a passive microwave frequency shifter used for back-modulation around 2 GHz. The interesting point was to develop this function with an integrated silicon micro-mechanical rotating structure. The paper describes the prototype of the RF MEMS already developed in ESIEE laboratory. And we insist on the microwave measurements performed and the associated equivalent models.

description: Grenzflächeneigenschaften von zwei unverträglichen Polymeren unterschiedlicher Steifigkeiten werden mittels gitterfreies Kugel-Stab-Modell und Monte-Carlo-Techniken untersucht. Die Bestimmung der Grenzflächenspannung erfolgt durch Anwendung des Virialsatzes und aus einer Analyse des Kapillarwellenspektrums. Grenzflächenprofile für Segment- und Kettenorientierung werden im Detail untersucht. Die Ergebnisse zeigen, daß die Grenzflächenspannung mit der Steifigkeit der semiflexiblen Komponente anwächst und mit wachsender Steifigkeit schnell in einen konstanten Wert einmündet. Dieser konstante Wert wird bereits deutlich unterhalb der Steifigkeit erreicht, bei der die semiflexiblen Polymere einen Übergang vom isotropen zum nematischen Zustand erfahren. Im tatsächlich semiflexiblen Bereich ergibt sich bei Berücksichtigung der Effekte endlicher Kettenlänge eine gute Übereinstimmung mit den Mean-Field-Resultaten. Die Ergebnisse zeigen, daß χc mit zunehmender Steifigkeit der semiflexiblen Komponente abnimmt. Im Rahmen dieser Arbeit werden weiterhin die Grenzflächeneigenschaften der Polymere unter Berücksichtigung der Monomergröße untersucht.
description: Using a continuous space Rod Bead Model and an off-lattice Monte Carlo technique we investigate interfacial properties between two incompatible polymers of different stiffnesses. The interfacial tension is determined by using virial theorem and analyzing the spectrum of capillary waves. Detailed interfacial profiles for segment and chain densities and orientations are obtained. The simulation results agree with mean field approaches for not too large stiffness disparities and show a marked tendency towards a plateau at higher stiffness disparities where the differences to mean field approaches increase. Further, the results show that χc decreases with stiffness of the semiflexible components. The interfacial properties of polymers of different monomer sizes also have been studied.

description: The Photoluminescent (PL) measurements on photons and the transport measurements on excitons are the two types of independent and complementary detection tools to search for possible exciton superfluids in electron-hole semi-conductor bilayer systems. In fact, it was believed that the transport measurements can provide more direct evidences on superfluids than the spectroscopic measurements. It is important to establish the relations between the two kinds of measurements. In this paper, using quantum Heisenberg-Langevin equations, we establish such a connection by calculating various exciton correlation functions in the putative exciton superfluids. These correlation functions include both normal and anomalous Greater, Lesser, Advanced, Retarded, and Time-ordered exciton Green functions and also various two exciton correlation functions. We also evaluate the corresponding normal and anomalous spectral weights and the Keldysh distribution functions. We stress the violations of the fluctuation and dissipation theorem among these various exciton correlation functions in the non-equilibrium exciton superfluids. We also explore the input-output relations between various exciton correlation functions and those of emitted photons such as the angle resolved photon power spectrum, phase sensitive two mode squeezing spectrum and two photon correlations. Applications to possible superfluids in the exciton-polariton systems are also mentioned. For a comparison, using conventional imaginary time formalism, we also calculate all the exciton correlation functions in an equilibrium dissipative exciton superfluid in the electron-electron coupled semi-conductor bilayers at the quantum Hall regime at the total filling factor $ ν_T= 1 $. We stress the analogies and also important differences between the correlations functions in the two exciton superfluid systems.

description: Clinical and laboratory studies over recent decades have established branched evolution as a feature of cancer. However, while grounded in somatic selection, several lines of evidence suggest a Darwinian model alone is insufficient to fully explain cancer evolution. First, the role of macroevolutionary events in tumour initiation and progression contradicts Darwin's central thesis of gradualism. Whole-genome doubling, chromosomal chromoplexy and chromothripsis represent examples of single catastrophic events which can drive tumour evolution. Second, neutral evolution can play a role in some tumours, indicating that selection is not always driving evolution. Third, increasing appreciation of the role of the ageing soma has led to recent generalised theories of age-dependent carcinogenesis. Here, we review these concepts and others, which collectively argue for a model of cancer evolution which extends beyond Darwin. We also highlight clinical opportunities which can be grasped through targeting cancer vulnerabilities arising from non-Darwinian patterns of evolution.

description: A broadband ground gate amplifier was designed, fabricated and characterized. Noise parameters of the intrinsic HFETs were measured and simulated by using Pospieszalski noise model. Extracted drain and gate temperatures were used for the characterization of the amplifier noise properties. An input match better than -20 dB in a wide band from 2 to 6 GHz and -10 dB from 1-13 GHz with corresponding 11 dB gain was obtained. NF min of 3 dB was found experimentally at room temperature. A dc power dissipation of less than 20 mW is possible to obtain with this device technology. The total chip area is 2x1.5 mm 2. The active circuit area is less than 1 mm 2. We have simulated amplifiers rf and noise performance with the wider gate HFET at the input.

Optimization of neutrino oscillation facilities for large θ_{13}

description: Up to now, future neutrino beam experiments have been designed and optimized in order to look for CP violation, θ_{13} and the mass hierarchy under the conservative assumption that θ_{13} is very small. However, the recent results from T2K and MINOS favor a θ_{13} which could be as large as 8^{\circ}. In this work, we propose a re-optimization for neutrino beam experiments in case this hint is confirmed. By switching from the first to the second oscillation peak, we find that the CP discovery potential of future oscillation experiments would not only be enhanced, but it would also be less affected by systematic uncertainties. In order to illustrate the effect, we present our results for a Super-Beam experiment, comparing the results obtained at the first and the second oscillation peaks for several values of the systematic errors. We also study its combination with a β-beam facility and show that the synergy between both experiments would also be enhanced due to the larger L/E. Moreover, the increased matter effects at the larger L/E also significantly improves the sensitivity to the mass hierarchy.

Phase Noise Analysis of MEMS-Based Phase Shifters

Year: 2001
Subjects: ING-INF/01 Elettronica

description: The effect of Brownian noise on Micro-Electro-Mechanical (MEMS)-based circuits has been calculated for MEMS-based circuits (phase shifters, delay circuits). The calculations are done for capaci-tive shunt MEMS switches and metal-to-metal contact series MEMS switches. The phase noise due to Brownian motion is negligible for MEMS switches with k ' 10 N/m, g0 > 2 µm, Q > 0.5, and f0 ' 50 kHz. It is also found that metal-to-metal contact series switches result in much less phase noise than standard capacitive shunt switches. The phase noise increases rapidly for low spring-constant bridges (k =0.2-4 N/m), low-height bridges, and for bridges with a large mechanical damping (Q < 0.3). Also, varactor-based de-signs result in 30-40 dB more phase noise than switch-based circuits. The paper proves that microwave passive circuits built using MEMS switches (with a proper mechanical design) can be used in most commercial and military applications without any phase noise penalty.

S-parameters have been measured at different DC magnetic bias fields, with a frequency tunability between 2 GHz and 6 GHz ca.. An improvement of the performances for the SERs excited by micromachined microstrip transducers has been clearly demonstrated. Moreover, the utilization of silicon membranes to support MSW-SERs offers important openings toward the integration of magnetostatic wave devices with micromachined structures.

description: This paper focus on the design of MEMS distributed tunable millimeter wave filters. A two pole filter continuously tunable in bandwidth and in frequency with constant input/output impedance is described. The center frequency can be tuned from 37.8 GHz to 40.4 GHz and the bandwidth can be changed from 1.6 GHz to 1 GHz with constant return losses.

description: We study the internal dynamics of an elementary quantum system placed close to a body held at a temperature different from that of the surrounding radiation. We derive general expressions for lifetime and density matrix valid for bodies of arbitrary geometry and dielectric permittivity. Out of equilibrium, the thermalization process and steady states become both qualitatively and quantitatively significantly different from the case of radiation at thermal equilibrium. For the case of a three-level atom close to a slab of finite thickness, we predict the occurrence of population inversion and an efficient cooling mechanism for the quantum system, whose effective internal temperature can be driven to values much lower than both involved temperatures. Our results show that non-equilibrium configurations provide new promising ways to control the state of an atomic system.

description: We analyze the role played by Long Distance Symmetries within the context of the Similarity Renormalization Group (SRG) approach, which is based on phase-shift preserving continuous unitary transformations that evolve hamiltonians with a cutoff on energy differences. We find that there is a SRG cutoff for which almost perfect fulfillment of Wigner symmetry is found. We discuss the possible consequences of such finding.

description: We investigate the shear viscosity of a pion gas in relativistic kinetic theory, using the Nambu-Jona-Lasinio model to construct the pion mass and the pi-pi interaction at finite temperature. Whereas at low temperatures the scattering properties and, hence, the viscosity are in agreement with lowest-order chiral perturbation theory, we find strong medium modifications in the crossover region. Here the system is strongly coupled and the scattering lengths diverge, similarly as for ultra-cold Fermi gases at a Feshbach resonance. As a consequence, the ratio eta/s is found to be strongly reduced as compared to calculations without medium-modified masses and scattering amplitudes. However, the quantitative results are very sensitive to the details of the applied approximations.

description: Controllability -- the possibility of performing any target dynamics by applying a set of available operations -- is a fundamental requirement for the practical use of any physical system. For finite-dimensional systems, as for instance spin systems, precise criterions to establish controllability, such as the so called rank criterion, are well known. However most physical systems require a description in terms of an infinite-dimensional Hilbert space whose controllability properties are poorly understood. Here, we investigate infinite-dimensional bosonic quantum systems -- encompassing quantum light, ensembles of bosonic atoms, motional degrees of freedom of ions, and nano-mechanical oscillators -- governed by quadratic Hamiltonians (such that their evolution is analogous to coupled harmonic oscillators). After having highlighted the intimate connection between controllability and recurrence in the Hilbert space, we prove that, for coupled oscillators, a simple extra condition has to be fulfilled to extend the rank criterion to infinite dimensional quadratic systems. Further, we present a useful application of our finding, by proving indirect controllability of a chain of harmonic oscillators.

Bridging silos : increasing collaborative teamwork between family physicians and home health staff
Creators: name: Berg, Shannon
Publisher: name: University of British Columbia

description: Family physicians (FPs) and home health staff (HHS – home care nurses, case managers, occupational and physiotherapists, and nutritionists) share complex acute and chronically ill patients, but experience significant barriers to collaborative care. This study employed a mixed methodology design to assess the effectiveness of use by FPs and HHS of a structured communication process (pre-scheduled, secure audio-conferencing) about patients they shared, involving all HHS staff and a convenience sample of 22 FPs providing service in one geographic area of a large multi-cultural Canadian city. Following a three-month baseline measurement period, FPs were randomized to an intervention or usual communication group, and the intervention was applied for eight months. Outcome measures included number of shared patients; total number of contacts about shared patients; changes in perception of quality of collaboration; and qualitative experience of using the intervention. Primary data sources included extracts and chart reviews from the HHS electronic clinical documentation system; pre- and post-study administration of a published survey designed to measure perception of collaboration for FPs and home care staff ; and post-study semi-structured interviews and focus groups. Non-parametric statistical procedures and mixed effects Poisson regression for longitudinal count data were used for quantitative data, and thematic content analysis for qualitative data. Results from quantitative and qualitative analysis were considered overall to generate insights into how to further collaborative care planning between FPs and HHS. The average number of shared patients per FP per month did not change, but a statistically significant increase was observed in the average number of contacts per shared patient between FPs and HHS for both study groups in the intervention phase. FPs and HHS agreed that the conferences were beneficial for patients, and both gained a better understanding of each others’ services and work processes. Both FPs and HHS provided evidence that structural barriers greatly impede collaboration between primary and community care. Use of audio-conferencing may have provided a proactive, efficient method of communication that avoided the need for subsequent back-and-forth clarification. Limitations included the small sample size of FPs and short timeline of the intervention period given the magnitude of the change expected.
Higgs decay with monophoton + MET signature from low scale supersymmetry breaking

description: We study the decay of a standard model-like Higgs boson into a gravitino and a neutralino, which subsequently decays promptly into another gravitino and a photon. Such a decay can be important in scenarios where the supersymmetry breaking scale is of the order of a few TeV, and in the region of low transverse momenta of the photon, it may provide the dominant contribution to the final state with a photon and two gravitinos. We estimate the relevant standard model backgrounds and the prospects for discovering this Higgs decay through a photon and missing transverse energy signal at the LHC in terms of a simplified model. We also give an explicit model with manifest, but spontaneously broken, supersymmetry in which the usual MSSM soft terms are promoted to supersymmetric operators involving a dynamical goldstino supermultiplet. This model can give rise to a SM-like CP-even neutral Higgs particle with a mass of 125 GeV, without requiring substantial radiative corrections, and with couplings sufficiently large for a signal discovery through the above mentioned Higgs decay channel with the upcoming data from the LHC.

description: In der vorliegenden Untersuchung wurde erstmalig eine Methode zum Nachweis von Spender-spezifischen anti-HLA Antikörpern (DSA), die einen Einfluss auf das Überleben von Corneatransplantaten zeigen, für den Gebrauch in der Routinediagnostik vorgestellt. Auf Grund nicht zur Verfügung stehender vitaler Lymphozyten erfolgt unmittelbar vor der Cornea-Transplantation (TX) regulär kein Kreuztest zum Ausschluss von DSA. Obwohl die Cornea ein „immunprivilegiertes Organ“ darstellt, wurden in zurückliegenden Studien bei 10-18% der erst- und bei ca. 60% der mehrfach transplantierten Empfänger Abstoßungsreaktionen immunologischen Ursprunges beobachtet. Der kommerziell vertriebene ELISA Testkit „Antibody Monitoring System” wurde so modifiziert, dass aus dem äußeren Ring des Corneatransplantates als Spendermaterial herausgelöste HLA-Moleküle eingesetzt wurden. Bei 42% der Patienten eines Gesamtkollektivs von Corneaempfängern (n = 45) konnten DSA gegen HLA Klasse I und/oder Klasse II Merkmale des Spenders nachgewiesen werden. Von diesen DSA-positiven Patienten zeigten etwa 80% (hyper-) akute immunologische Abstoßungsphänomene, die teilweise mit einem Transplantatverlust endeten, der sich zwischen den ersten Tagen und den ersten zwei Monaten nach der Transplantation manifestierte. Derartige Rejektionsphänomene waren dagegen lediglich in etwa 20% der Rezipienten aus der Patientengruppe zu beobachten, in denen keine DSA nachweisbar waren. Der Beobachtungszeitraum umfasste insgesamt zehn Monate. Die Studie legt nahe, dass der Nachweis und die diagnostische Bewertung gegen HLA-Merkmale der Spender gerichteter Antikörper in potentiellen Corneatransplantat-Empfängern einen nicht unerheb-lichen Einfluss auf das Überleben des Transplantates ausübt. Dies gilt insbesondere für sogenannte Risikoempfänger, für die postuliert werden muss, dass sich bei ihnen ein durch (hyper-) akute Rejektionsepisoden bedingter Transplantatverlust durch den Ausschluss von DSA minimieren lässt.

description: A wide spectrum of electrokinetic studies is modelled as isothermal ones to expedite analysis even when such conditions may be extremely difficult to realize in practice. As a clear and novel departure from this trend, we address the case of flow-induced electrohydrodynamics, commonly referred to as streaming potential, in a situation where finite temperature gradients do indeed exist. By way of analysing a model problem of flow through a narrow parallel plate channel, we show that the temperature gradients have a significant effect on the streaming potential, and, consequently, on the flow itself. We incorporate thermoelectric effects in our model by a full-fledged coupling among the electric potential, the ionic species distribution, the fluid velocity and the local fluid temperature fields without resorting to ad hoc simplifications. We expect this expository study to contribute towards more sophisticated future inquiries into practical micro-/nano-fluidic applications coupling thermal field focusing with electrokinetic effects.
