description: A usual code for quantum wiretap channel requires an auxiliary random variable subject to the perfect uniform distribution. However, it is difficult to prepare such an auxiliary random variable. We propose a code that requires only an auxiliary random variable subject to a non-uniform distribution instead of the perfect uniform distribution. Further, we evaluate the exponential decreasing rate of leaked information and derive its equivocation rate. For practical constructions, we also discuss the security when our code consists of a linear error correcting code.

description: In this paper a single balanced mixer, suitable for K band applications, is described. The prototype is realized usingan InP process and it is based on Heterojunction Interband Tunnel Diodes (HITDs). The circuit, consisting of a pair of HITD sconnected to a coplanar Lange coupler, is optimized by a proper diode scaling in the 19-26 GHzband, providing an IF ranging from zero up to 7GHz. Measurements highlight a conversion loss ranging from 6dB to 10dB and an IIP3 of 8dB in the desired band. Due to the diodes characteristic no DC supply is needed and the functionalityis achieved with a LO power of -2dBm.The results also show a good agreement between the experimental data and simulations.

description: Die Machtübernahme der Nationalsozialisten 1933 bedingte einen prägenden Einschnitt im Umgang mit psychisch kranken und behinderten Menschen. Bereits seit der Jahrhundertwende war in Wissenschaft und zunehmend auch in der Öffentlichkeit weltweit über die Verbesserung des menschlichen Erbgutes und die Ausrottung von Erbkrankheiten diskutiert worden. Die stärkste Umsetzung von Zwangssterilisationsmaßnahmen fand sich ab 1934 jedoch im Dritten Reich, wo parallel auch die Ermordung hilfloser Kranker durch Hunger, Vergasung, und die Gabe tödlicher Medikamente geplant und ab 1939 umgesetzt wurde. Auch die damalige Landesheilanstalt Uchtspringe wurde unter den Nationalsozialisten zu einem Ort des Schreckens. Zwischen 1934 und 1945 fanden mindestens 760 Zwangssterilisationen statt, mehrere tausend Menschen wurden im Rahmen von Deportationen oder in der Heilanstalt selbst ermordet. Die hier vorgelegte Arbeit soll einen Beitrag zur Aufarbeitung nationalsozialistischer Verbrechen leisten. Sie ermöglicht durch die umfangreiche Auswertung verschiedenster, bisher kaum untersuchter Archivalien die detaillierte Darstellung der Zwangssterilisationsmaßnahmen in Uchtspringe und erlaubt Rückschlüsse auf bisher wenig beleuchtete Aspekte der deutschlandweiten Umsetzung des Gesetzes zur Verhütung erbkranken Nachwuchses wie z.B. die Implementierung von Gesetzesänderungen sowie die Pflegerbestellung. Die Portraitierung der wichtigsten Operateure ermöglicht zudem neue Einblicke in deren Motivation und den Umgang mit NS-Tätern in der sowjetischen Besatzungszone.

description: Blind quantum computation is a novel secure quantum-computing protocol that enables Alice, who does not have sufficient quantum technology at her disposal, to delegate her quantum computation to Bob, who has a fully fledged quantum computer, in such a way that Bob cannot learn anything about Alice's input, output and algorithm. A recent proof-of-principle experiment demonstrating blind quantum computation in an optical system has raised new challenges regarding the scalability of blind quantum computation in realistic noisy conditions. Here we show that fault-tolerant blind quantum computation is possible in a topologically protected manner using the Raussendorf-Harrington-Goyal scheme. The error threshold of our scheme is 0.0043, which is comparable to that (0.0075) of non-blind topological quantum computation. As the error per gate of the order 0.001 was already achieved in some experimental systems, our result implies that secure cloud quantum computation is within reach.

description: The industrially manufactured low-noise GaAs FET noise and gain parameters were experimentally investigated in the temperature range of 80-300 K at frequency 12 GHz. The process of cooling down to the 80 K permits to reduce the minimum noise figure of the studied samples to - 1 dB; simultaneously the associated gain increases up to ~ 2 -2.5 dB. The comparative analysis of minimum noise figure changing in temperature range in accordance to the semiconductor physical parameters was carried out. It was established that the noise figure minimum under the cooling depends essentially on the carrier concentration of epitaxial structure.

description: The electrical behaviour of an undoped, MBE-grown, asymmetric thickness-double barrier single quantum well (QW) infrared photodetector structures were studied. The structures consisted of 100-200 A thick Al0.27Ga0.73As emitter barrier, a 40 A thick GaAs quantum well (QW) and a 500 A thick Al0.27Ga0.73As collector barrier. In order to describe the current generation mechanisms, the resonance current and the non-resonance current from emitter contact to QW, and the field emission current from the QW were simulated by numerical calculations. Calculated and the measured currents were in good agreement. Our result showed that the QW carrier density increased with reduced emitter barrier thickness enhancing the detector performance but at the cost of increased noise levels with dark current.

Sparse signal recovery : analysis and synthesis formulations with prior support information
Creators: name: Hargreaves, Brock Edward
Publisher: name: University of British Columbia
Year: 2014

description: The synthesis model for signal recovery has been the model of choice for many years in compressive sensing. Various weighting schemes using prior support information to adjust the objective function associated with the synthesis model have been shown to improve the recovery of the signal in terms of accuracy. Generally, even with no prior knowledge of the support, iterative methods can build support estimates and incorporate that into the recovery which has also been shown to increase the speed and accuracy of the recovery. However when the original signal is sparse with respect to a redundant dictionary (rather than an orthonormal basis) there is a coun- terpart model to synthesis, namely the analysis model, which has been less popular but has recently attracted more attention. The analysis model is much less understood and thus there are fewer theorems available in both the context of non-weighted and weighted signal recovery. In this thesis, we investigate weighting in both the analysis model and synthesis model in weighted l-1 minimization. Theoretical guarantees on reconstruction and various weighting strategies for each model are discussed. We give conditions for weighted synthesis recovery with frames which do not require strict incoherency conditions, this is based on recent results of regular synthesis with frames using optimal dual l-1 analysis. A novel weighting technique is introduced in the analysis case which outperforms its traditional counterparts in the case of seismic wavefield reconstruction. We also introduce a weighted split Bregman algorithm for analysis and optimal dual analysis. We then investigate these techniques on seismic data and synthetically created test data using a variety of frames.

description: A novel combination of a packaged GaAs MMIC with a microstrip-coupled slot high performance 180° hybrid constitutes a downconverter, which provides the very low intermodulation level required by some TV applications. The packaged chip was mounted on a substrate together with a high performance and seldom-used MIC 180° hybrid. No adjustable filters are required due to the broadband behavior of the whole downconverter. This feature is required for cost reduction. A double-balanced mixer and the LO balun have been integrated in the same chip. A properly biased cold FET was used in the mixer to achieve low distortion frequency mixing. An active phase splitter was chosen as the LO balun in order to get small phase errors over a wide frequency band. The MIC 180° hybrid, which makes use of microstrip lines, slot lines and coupled-slot lines, was used as the RF balun. The topology used for this hybrid makes it very useful for balanced mixers, since there is no crossing of MIC transmission lines. On the other hand, there are no active elements, so no distortion is added to the downconverter. The hybrid was designed with an intensive use of a quasy-planar electromagnetic simulator. MMIC package modeling is also discussed in the paper. The MMIC was fabricated using the F20 process of the GEC Marconi foundry. Conversion losses of 8.5 dB can be obtained for the whole downconverter with a LO drive of 5.5 dBm. A 3rd order intercept point of 21 dBm of output power and a spectral purity in the complete RF frequency band of more than 70 dB were achieved.

description: We consider a class of linear Volterra transforms of Brownian motion associated to a sequence of Müntz Gaussian spaces and determine explicitly their kernels; some interesting links with Müntz-Legendre polynomials are provided. This gives new explicit examples of progressive Gaussian enlargement of the Brownian filtration. By exploiting a link to stationarity, we give a necessary and sufficient condition for the existence of kernels of infinite order associated to an infinite dimensional Müntz Gaussian space; we also examine when the transformed Brownian motion remains a semimartingale in the filtration of the original process.

Zunächst untersuche ich die Auswirkungen des Klimawandels und der Landnutzung auf die biologische Vielfalt und die Ökosystemleistungen durch einen Modellvergleich. Dann entwickle und beschreibe ich einen neuen Szenariorahmen "Nature Futures Framework" mit seinem methodischen Leitfaden für die Modellierung von Nature Futures Szenarien. Abschließend führe ich eine retrospektive Analyse von Schutzgebieten durch die "Nature Futures"-Linse unter Verwendung wesentlicher Variablen durch. In dieser Dissertation wird vorgeschlagen, Klima- und Biodiversitätsforschungsgemeinschaften bei der Entwicklung von Nachhaltigkeitsszenarien zusammenzubringen. Sie fördert die Integration verschiedener Werte und Weltanschauungen in Szenarien, um breitere gesellschaftliche Interessengruppen in die Erreichung nachhaltiger Zukünfte einzubinden.

First, I explore the impact of climate change and land use on biodiversity and ecosystem services through a model intercomparison. Then, I co-develop and describe a new scenario framework “Nature Futures Framework” with its methodological guide for modeling Nature Futures scenarios. Finally, I conduct a retrospective analysis on protected areas through the Nature Futures lens using essential variables. This dissertation proposes bringing climate and biodiversity research communities together in developing sustainability scenarios. It promotes integrating diverse values and worldviews in new scenarios to engage broader societal stakeholders in achieving sustainable futures. It suggests interweaving scientific and policy frameworks in implementing conservation and sustainability goals.

description: We perform a finite sample analysis of the detection levels for sparse principal components of a high-dimensional covariance matrix. Our minimax optimal test is based on a sparse eigenvalue statistic. Alas, computing this test is known to be NP-complete in general, and we describe a computationally efficient alternative test using convex relaxations. Our relaxation is also proved to detect sparse principal components at near optimal detection levels, and it performs well on simulated datasets. Moreover, using polynomial time reductions from theoretical computer science, we bring significant evidence that our results cannot be improved, thus revealing an inherent trade off between statistical and computational performance.

Bisherige Therapien brachten keine Heilung, sodass neue Forschungsfelder gesucht werden. Die Ursachen für kognitive Einschränkungen sind divers. In jüngster Zeit ist zunehmend die Neuroinflammation in den Fokus gerückt und könnte Therapieoptionen bei dementen Personen offenhalten. Im Rahmen dieser Arbeit wurde der Liquor cerebrospinalis von insgesamt 190 Probanden (mit Alzheimer-Demenz, MCI, Vaskulärer Demenz, Frontotemporaler Demenz, Lewy-Körper-Demenz sowie Kontrollgruppe) auf Immunzellen untersucht. Dabei wurden bei Dementen im Vergleich zur nicht-dementen Kontrollgruppe signifikante Unterschiede im angeborenen und erworbenen Immunsystem detektiert, die Ansatz für weitere Untersuchungen sein könnten.
AlGaInN power transistors: status and prospects

Subjects: ING-INF/01 Elettronica

description: InN, GaN, A1N and their alloys were first studied in the 1960's for application to short wavelength emitters and for high power/high temperature electronics. These efforts languished due to the lack of a bulk substrate technology and the inability to produce low defect and low impurity heteroepitaxy films. In light of this, the compound semiconductor community moved on to Arsenide- and Phosphide-based materials that resulted in the device technologies now driving microwave wireless communications and many military electromagnetic systems. AlGalnN materials, however, are now poised to challenge the conventional III-V semiconductors for power generation, at least up to K-band, as a result of drastic material improvements driven, initially, by photonic applications. In this talk, the status of AlGaN/GaN high electron mobility transistors (HEMTs) and heterojunction bipolar transistors (HBTs) will be presented. Ongoing and future work to increase the operating frequency and output power will also be addressed.

description: We introduce a new concept of dimension for metric spaces, the so-called topological Hausdorff dimension. It is defined by a very natural combination of the definitions of the topological dimension and the Hausdorff dimension. The value of the topological Hausdorff dimension is always between the topological dimension and the Hausdorff dimension, in particular, this new dimension is a non-trivial lower estimate for the Hausdorff dimension. We examine the basic properties of this new notion of dimension, compare it to other well-known notions, determine its value for some classical fractals such as the Sierpinski carpet, the von Koch snowflake curve, Kakeya sets, the trail of the Brownian motion, etc. As our first application, we generalize the celebrated result of Chayes, Chayes and Durrett about the phase transition of the connectedness of the limit set of Mandelbrot's fractal percolation process. They proved that certain curves show up in the limit set when passing a critical probability, and we prove that actually `thick' families of curves show up, where roughly speaking the word thick means that the curves can be parametrized in a natural way by a set of large Hausdorff dimension. The proof of this is basically a lower estimate of the topological Hausdorff dimension of the limit set. For the sake of completeness, we also give an upper estimate and conclude that in the non-trivial cases the topological Hausdorff dimension is almost surely strictly below the Hausdorff dimension. Finally, as our second application, we show that the topological Hausdorff dimension is precisely the right notion to describe the Hausdorff dimension of the level sets of the generic continuous function (in the sense of Baire category) defined on a compact metric space.

description: We report on AlxInyGal-x-yN-GaN heterojunctions grown on sapphire and 6H/4H SiC substrates using a low pressure MOCVD. Based on a linear extrapolation of lattice constants as functions of molar fractions, we estimate that quaternary AlxInyGal-x-yN layers with Al/In mole fraction ratio of 5 should be nearly lattice-matched to GaN. The independent control of strain and of the band offset has been confirmed by X-ray and photoluminescence data. For AlxInyGal-x-yN-GaN junctions with barrier thickness less than 50 nm and varying alloy compositions (x from 0.1 to 0.2 and y from 0.00 to 0.02), room temperature sheet-carrier density and mobility values ranging from 0.5-1.5 x 1013cm ~2 and 1000-1500 cm2V-1sec-1 were measured. The mobility values increase by about a factor of 5 upon cooling to 77 K. This establishes the presence of the two-dimensional electron gas at the AlxInyGal-x-yN-GaN heterojunction interface and confirms a high quality of heterointerfaces. We also fabricated AlxInyGal-x-yN-GaN HFETs with the state-of-the art performance. The fabrication technology for these devices is substantially different from that for conventional AlGaN/GaN HEMTs. We will report on DC and microwave characteristics of these devices and compare these characteristics with those for conventional GaN-based HFETs.

description: In contrast to the predictions of the unified model, some X-ray unobscured Seyfert 2 galaxies have been discovered in the last decade. One of them, the starburst/Seyfert composite galaxy IRAS 01072+4954 (z=0.0236), has a typical Type~1 X-ray emission, while its optical spectrum resembles an HII galaxy and lacks the expected broad lines. We performed near-infrared integral-field observations of this object with the aim to determine the nature of its nuclear emission and to find indications for the existence or absence of a broad-line region. Several reasons have been proposed to explain such peculiar emission. We studied the validity of such hypotheses, including the possibility for it to be True-Seyfert~2. We found little obscuration towards the nucleus A_V = 2.5 mag, and a nuclear star-formation rate Sigma_SFR < 11.6 Msun yr^{-1} kpc^{-2}, which is below the average in Seyferts. Unresolved hot-dust emission with T ~ 1150 K seems to indicate the presence of a torus with its axis close to the line of sight. We found that IRAS 01072+4954 hosts a low mass black hole with an estimated mass of M_BH ~ 10^5 Msun and an upper limit of 2.5x10^6 Msun. Its bolometric luminosity is L_bol ~ 2.5x10^{42} erg/s, which yields a high accretion rate with an Eddington ratio ~ 0.2. If the relations found in more massive systems also apply to this case, then IRAS 01072+4954 should show broad emission lines with FWHM_{broad} ~(400-600) km/s. Indeed, some indications for such narrow broad-line components are seen in our data, but the evidence is not yet conclusive. This source thus seems not to be a True-Seyfert 2, but an extreme case of a narrow line Seyfert 1, which, due to the faintness of the active nucleus, does not have strong FeII emission in the optical.

description: Krebs ist eine Krankheit deren Therapie mit Nebenwirkungen und schlechten Prognosen verbunden ist. Somit ist die Erforschung neuer Therapien wichtig. Diese Arbeit leistet ihren Beitrag auf diesem Gebiet, durch die Entwicklung potenter Inhibitoren gegen die Histondeacetylasen HDAC8 & 10. HDACs spielen bei der Entstehung und dem Lebenszyklus verschiedener Krebszellen eine Rolle. Studien haben gezeigt, dass eine HDAC-Inhibition ein vielversprechender Ansatz zur Therapie diverser Tumorerkrankungen ist. In dieser Arbeit wurden potente und selektive Inhibitoren gegen HDAC8 & 10 synthetisiert, biochemisch charakterisiert und hinsichtlich ihrer Struktur-Wirkungs-Beziehungen untersucht. Die aktivsten und selektivsten Derivate wurden an ausgewählten Neuroblastom- (HDAC8) und Leukämiezellen (HDAC10) getestet und stellten sich hier als vielversprechende Kandidaten heraus. Ebenso wurden die synthetisierten Inhibitoren in Zytotoxizitätsassays an humanen HEK293 Zellen als nicht-toxisch klassifiziert.
description: Cancer is a disease that affects more and more people, and the treatment is associated with side effects and partially poor prognoses. Therefore, it is important that new therapies are researched. This work contributes to this field by developing potent inhibitors for the histone deacetyases HDAC8 & 10. HDACs play a significant role in the development and life cycle of several cancer cells. Previous studies have shown that the inhibition of distinct HDACs is a promising approach for chemotherapy of various types of tumor diseases. In this work potent and selective HDAC8 and HDAC10 inhibitors were synthesized, biochemically characterized and examined concerning to their structure-activity relationships. The most active and selective derivatives were tested on selected neuroblastoma (HDAC8) and leukemia (HDAC10) cells and turned out to be potent and promising candidates. In addition, the synthesized inhibitors were classified as nontoxic in cytotoxicity assays using human HEK293 cells.

description: Scanning Thermal Microscopy (SThM) uses micromachined thermal sensors integrated in a force sensing cantilever with a nanoscale tip can be highly useful for exploration of thermal management of nanoscale semiconductor devices. As well as mapping of surface properties of related materials. Whereas SThM is capable to image externally generated heat with nanoscale resolution, its ability to map and measure thermal conductivity of materials has been mainly limited to polymers or similar materials possessing low thermal conductivity in the range from 0.1 to 1 W/mK, with lateral resolution on the order of 1 \mum. In this paper we use linked experimental and theoretical approaches to analyse thermal performance and sensitivity of the micromachined SThM probes in order to expand their applicability to a broader range of nanostructures from polymers to semiconductors and metals. We develop physical models of interlinked thermal and electrical phenomena in these probes and then validate these models using experimental measurements of the real probes, which provided the basis for analysing SThM performance in exploration of nanostructures. Our study then highlights critical features of these probes, namely, the geometrical location of the thermal sensor with respect to the probe apex, thermal conductance of the probe to the support base, heat conduction to the surrounding gas, and the thermal conductivity of tip material adjacent to the apex. It is furthermore allows us to propose a novel design of the SThM probe that incorporates a carbon nanotube (CNT) or similar high thermal conductivity graphene sheet material positioned near the probe apex. The new sensor is predicted to provide spatial resolution to the thermal properties of nanostructures on the order of few tens of nm, as well as to expand the sensitivity of the SThM probe to materials with heat conductivity values up to 100-1000 W/mK.

description: An unstable torsion free sheaf on a smooth projective variety gives a GIT unstable point in certain Quot scheme. To a GIT unstable point, Kempf associates a "maximally destabilizing" 1-parameter subgroup, and this induces a filtration of the torsion free sheaf. We show that this filtration coincides with the Harder-Narasimhan filtration.

description: Ernährungsmitbedingte Erkrankungen, z. B. Herz-Kreislauf-Erkrankungen, verursachen einen Großteil der Todesfälle in Deutschland. Gleichfalls ist ein steigender Konsum von Speisen außer Haus feststellbar. Daher kann mit einer ernährungsphysiologischen Optimierung von Speisenrezepturen in der Außer-Haus-Verpflegung ein wichtiger Beitrag zur Steigerung der Ernährungsqualität und Gesunderhaltung allgemein geleistet werden. Obgleich es schon vereinzelt Ansätze gibt, Ernährungsmuster und Speisen zu bewerten, fehlt es an einem geeigneten Modell zur Bewertung einzelner Rezepturen auf Nährstoffebene und einem Konzept, wie dieses auch an Praxispartner herangetragen werden kann. Zudem sind der Bewerbung gesundheitsförderlicher Speisen Grenzen im Rahmen der EU-Gesetzgebung gesetzt. Daher hat sich die vorliegende Arbeit mit der interdisziplinären und ganzheitlichen Konzeption eines Modells beschäftigt, von rechtlichen über kommunikative bis hin zu sozioökonomischen Aspekten. Daraufhin wurde exemplarisch ein Modell zur Bewertung von Speisen in der Außer-Haus-Verpflegung entwickelt, das gängige Hürden meistert und Schwachstellen verbessert.
description: Diseases related to nutrition, e. g. coronary heart diseases, account für a majority of deaths in Germany. At the same time, the numbers for eating-out-of-home are increasing. Therefore, the optimisation of meals in public catering can contribute to an improvement of nutritional quality and health in general. Despite various attempts to assess nutritional patterns and foods, there is a lack of an adequate model to assess single recipes on the basis of nutrients and a lack of a concept on how to address project partners. Further, the EU legislations sets boundaries for advertisments of healthier meals. Therefore, this monograph focused on the interdisciplinary and holistic conception of a model, from legal to communicative and socioeconomic aspects. Existing models were examined. Based on that, a model for the assessment of meals in public catering was exemplarily developed, which should avoid common obstacles and limitations

description: Confidence intervals and joint confidence sets are constructed for the nonparametric calibration of exponential Lévy models based on prices of European options. To this end, we show joint asymptotic normality in the spectral calibration method for the estimators of the volatility, the drift, the jump intensity and the Lévy density at finitely many points.

description: Defects in chloroplast development are ‘retrograde-signalled’ to the nucleus, reducing synthesis of photosynthetic or related proteins. The Arabidopsis cue8 mutant manifests virescence, a slow-greening phenotype, and is defective at an early stage in plastid development. Greening cotyledons or early leaf cells of cue8 exhibit immature chloroplasts which fail to fill the available cellular space. Such chloroplasts show reduced expression of genes of photosynthetic function, dependent on the plastid-encoded polymerase (PEP), while the expression of genes of housekeeping function driven by the nucleus-encoded polymerase (NEP) is elevated, a phenotype shared with mutants in plastid genetic functions. We attribute this phenotype to reduced expression of specific PEP-controlling sigma factors, elevated expression of RPOT (NEP) genes and maintained replication of plastid genomes (resulting in densely coalesced nucleoids in the mutant), i.e. it is due to an anterograde nucleus-to-chloroplast correction, analogous to retention of a juvenile plastid state. Mutants in plastid protein import components, particularly those involved in housekeeping protein import, also show this ‘retro-anterograde’ correction. Loss of CUE8 also causes changes in mRNA editing. The overall response has strong fitness value: loss of GUN1, an integrator of retrograde signalling, abolishes elements of it (albeit not others, including editing changes), causing bleaching and eventual seedling lethality upon cue8 gun1. This highlights the adaptive significance of virescence and retrograde signalling.This article is part of the XXX ‘Retrograde signalling from endosymbiotic organelles’.

description: One of the main objectives in APOLLO project is to offer high quality services to farmers that will help them increase their productivity. The offerings can be summarized in 6different services i) Tillage scheduling, ii) Irrigation scheduling, iii) Crop growth monitoring, iv) Crop yield estimation, v) Weather forecasting (additional service) and vi) Management zones (additional service). Crop biomass is one of the biophysical parameters of crops that will be produced to support two of the services, namely crop growth monitoring and crop yield estimation. The services will be tested in three pilot areas: La Mancha (Spain), Pella (Greece) and Ruma (Serbia).

This deliverable consists of a set of User Guides and video tutorial and it is aimed to support the end-users in using the APOLLO platform in pilot phase. The training material reflects the currently developed functionalities of APOLLO.

description: While the constrained minimal supersymmetric standard model (CMSSM) with universal gaugino masses, m_{1/2}, scalar masses, m_0, and A-terms, A_0, defined at some high energy scale (usually taken to be the GUT scale) is motivated by general features of supergravity models, it does not carry all of the constraints imposed by minimal supergravity (mSUGRA). In particular, the CMSSM does not impose a relation between the trilinear and bilinear soft supersymmetry breaking terms, B_0 = A_0 - m_0, nor does it impose the relation between the soft scalar masses and the gravitino mass, m_0 = m_{3/2}. As a consequence, tan(β) is computed given values of the other CMSSM input parameters. By considering a Giudice-Masiero (GM) extension to mSUGRA, one can introduce new parameters to the Kähler potential which are associated with the Higgs sector and recover many of the standard CMSSM predictions. However, depending on the value of A_0, one may have a gravitino or a neutralino dark matter candidate. We also consider the consequences of imposing the universality conditions above the GUT scale. This GM extension provides a natural UV completion for the CMSSM.

Mediated giants : giant tree frames and social movements in British Columbia media, 1986-92

description: Research shows how appeals to save charismatic megafauna have been used effectively as tools in campaigns for larger conservation-oriented projects. However, analysis over parallel efforts with ‘charismatic megaflora’ – specifically giant trees – has largely been neglected. During the contentious period of land use debates in British Columbia of the late 1980s and early 1990s, Wilderness Preservation Movement (WPM) activists mobilized for collective action against monolithic forestry corporations. A rallying point for activists was spurred in part by the discovery of the largest Sitka Spruce trees in Canada, which were slated for clear-cut logging. In a concerted effort to prevent this harvest and mobilize public support for broader preservation efforts, WPM actors engaged in media outlets to shape the debate – often through giant tree frames. This research evaluates the framing of this land use debate around giant trees as an effective media outreach strategy for expanding support for preservation efforts, as well as exploring their underlying supportive frameworks. Content and network analyses of sample news media articles spanning the period 1986-92 assess the construction, salience, and relationships of giant tree frames in coverage of WPM. Analyses of a singular framing strategy reveal the efficacy of striking imagery as well as the repertoire of discursive tools underpinning efforts to communicate social movement ideals to larger audiences. Results suggest that the construction of environmental problems is largely reliant upon scientific rationale, whereas economic and emotional appeals either contest or reinforce scientific claims. Even with the ambivalent nature of science in constructing environmentalist claims, scientific framing successfully communicates environmental problem salience, potentially of import for contemporary collective action strategies.

description: It is shown that every measurable partition ${A_1,..., A_k}$ of $\mathbb{R}^3$ satisfies $$\sum_{i=1}^k||\int_{A_i} xe^{-\frac12||x||_2^2}dx||_2^2\le 9π^2.\qquad(*)$$ Let ${P_1,P_2,P_3}$ be the partition of $\mathbb{R}^2$ into $120^\circ$ sectors centered at the origin. The bound is sharp, with equality holding if $A_i=P_i\times \mathbb{R}$ for $i\in {1,2,3}$ and $A_i=\emptyset$ for $i\in \{4,...,k\}$ (up to measure zero corrections, orthogonal transformations and renumbering of the sets $\{A_1,...,A_k\}$). This settles positively the 3-dimensional Propeller Conjecture of Khot and Naor (FOCS 2008). The proof of reduces the problem to a finite set of numerical inequalities which are then verified with full rigor in a computer-assisted fashion. The main consequence (and motivation) of $(*)$ is complexity-theoretic: the Unique Games hardness threshold of the Kernel Clustering problem with $4 \times 4$ centered and spherical hypothesis matrix equals $\frac{2π}{3}$.

description: One of the major uncertainties in the dense matter equation of state has been the nuclear symmetry energy. The density dependence of the symmetry energy is important in nuclear astrophysics, as it controls the neutronization of matter in core-collapse supernovae, the radii of neutron stars and the thicknesses of their crusts, the rate of cooling of neutron stars, and the properties of nuclei involved in r-process nucleosynthesis. We show that fits of nuclear masses to experimental masses, combined with other experimental information from neutron skins, heavy ion collisions, giant dipole resonances and dipole polarizabilities, lead to stringent constraints on parameters that describe the symmetry energy near the nuclear saturation density. These constraints are remarkably consistent with inferences from theoretical calculations of pure neutron matter, and, furthermore, with astrophysical observations of neutron stars. The concordance of experimental, theoretical and observational analyses suggests that the symmetry parameters S_v and L are in the range 29.0 - 32.7 MeV and 40.5 - 61.9 MeV, respectively, and that the neutron star radius, for a 1.4 M_sun star, is in the narrow window 10.7 km < R < 13.1 km (90% confidence). We can also set tight limits to the size of neutron star crusts and the fractional moment of inertia they contain, as well as the overall moment of inertia and quadrupole polarizability of 1.4 M_sun stars. Our results also have implications for the disk mass and ejected mass of compact mergers involving neutron stars.
