description: For a solar flare occurring on 2010 November 3, we present observations using several SDO/AIA extreme-ultraviolet (EUV) passbands of an erupting flux rope followed by inflows sweeping into a current sheet region. The inflows are soon followed by outflows appearing to originate from near the termination point of the inflowing motion - an observation in line with standard magnetic reconnection models. We measure average inflow plane-of-sky speeds to range from ~150-690 km/s with the initial, high-temperature inflows being the fastest. Using the inflow speeds and a range of Alfven speeds, we estimate the Alfvenic Mach number which appears to decrease with time. We also provide inflow and outflow times with respect to RHESSI count rates and find that the fast, high-temperature inflows occur simultaneously with a peak in the RHESSI thermal lightcurve. Five candidate inflow-outflow pairs are identified with no more than a minute delay between detections. The inflow speeds of these pairs are measured to be 10^2 km/s with outflow speeds ranging from 10^2-10^3 km/s - indicating acceleration during the reconnection process. The fastest of these outflows are in the form of apparently traveling density enhancements along the legs of the loops rather than the loop apexes themselves. These flows could either be accelerated plasma, shocks, or waves prompted by reconnection. The measurements presented here show an order of magnitude difference between the retraction speeds of the loops and the speed of the density enhancements within the loops - presumably exiting the reconnection site.

description: We will study some modifications to the notion of an exact C*-algebra by replacing the minimal tensor product with the reduced free product. First we will demonstrate how the reduced free product of a short exact sequence of C*-algebras with another C*-algebra may be taken. It will then be demonstrated that this operation preserves exact sequences. We will also establish that adjoining arbitrary k-tuples of operators in a free way behaves well with respect to taking ultrapowers.

description: The Fiedler value $λ_2$, also known as algebraic connectivity, is the second smallest Laplacian eigenvalue of a graph. We study the maximum Fiedler value among all planar graphs $G$ with $n$ vertices, denoted by $λ_{2\max}$, and we show the bounds $2+Θ(\frac{1}{n^2}) \leq λ_{2\max} \leq 2+O(\frac{1}{n})$. We also provide bounds on the maximum Fiedler value for the following classes of planar graphs: Bipartite planar graphs, bipartite planar graphs with minimum vertex degree~3, and outerplanar graphs. Furthermore, we derive almost tight bounds on $λ_{2\max}$ for two more classes of graphs, those of bounded genus and $K_h$-minor-free graphs.

description: The globular clusters are probably good targets for dark matter (DM) searches in $γ$-rays due to the possible adiabatic contraction of DM by baryons. In this work we analyse the three-year data collected by {\it Fermi} Large Area Telescope of globular clusters NGC 6388 and M 15 to search for possible DM signals. For NGC 6388 the detection of $γ$-ray emission was reported by {\it Fermi} collaboration, which is consistent with the emission of a population of millisecond pulsars. The spectral shape of NGC 6388 is also shown to be consistent with a DM contribution if assuming the annihilation final state is $b\bar{b}$. No significant $γ$-ray emission from M 15 is observed. We give the upper limits of DM contribution to $γ$-ray emission in both NGC 6388 and M 15, for annihilation final states $b\bar{b}$, $W^+W^-$, $μ^+μ^-$, $τ^+τ^-$ and monochromatic line. The constraints are stronger than that derived from observation of dwarf galaxies by {\it Fermi}.

description: Στην ακόλουθη διπλωματική εργασία πραγματοποιείται η διαδικασία της προμελέτης ενός δεξαμενοπλοίου. Αρχικά γίνεται μία σύντομη αναφορά στην θεωρία της μελέτης, καθώς επίσης και στις βασικές κατηγορίες των δεξαμενοπλοίων και στην εσωτερική τους διάταξη. Αφού οριστικοποιηθούν οι απαιτήσεις για το υπό μελέτη πλοίο, γίνεται ο υπολογισμός των βασικών του διαστάσεων, των συντελεστών μορφής και της ισχύος πρόωσης μέσω εμπειρικών τύπων από όμοια πλοία. Εν συνεχεία, πραγματοποιείται ο προϋπολογισμός των ομάδων βαρών του πλοίου και γίνεται η ανάλυση της μεταφορικής ικανότητας του πλοίου στις συνιστώσες του. Χρησιμοποιώντας το πρόγραμμα Rhinoceros 3D, αναπτύσσεται το σχέδιο γραμμών με την χρήση της μεθόδου Formdata, και διαμορφώνεται η εσωτερική του διάταξη με βάση τους κανονισμούς της MARPOL για δεξαμενόπλοια. Ύστερα, υπολογίζονται τα υδροστατικά μεγέθη και κατασκευάζεται το υδροστατικό διάγραμμα, με την χρήση του προγράμματος Maat Hydro. Αφού εκτιμηθεί το κέντρο βάρους του άφορτου αλλά πλήρως εξοπλισμένου πλοίου, γίνεται έλεγχος της άθικτης ευστάθειας του σε 4 διαφορετικές καταστάσεις φόρτωσης με βάση τα κριτήρια του κανονισμού A749(18) του IMO. Σε επόμενο βήμα, υπολογίζεται η συνολική αντίσταση που δέχεται το πλοίο με την μέθοδο Holtrop & Mennen, έτσι ώστε να γίνει η επιλογή των μέσων πρόωσης και συγκεκριμένα, της έλικας, της κύριας μηχανής, καθώς και του πηδαλίου. Επίσης, πραγματοποιείται η διαστασιολόγηση των διαμήκων στοιχείων της μέσης τομής και υπολογίζεται η αντοχή της. Τα αποτελέσματα αυτά, συγκρίνονται με βάση τα απαιτούμενα που ορίζουν οι CSR (Common Structural Rules). Τέλος, εκτιμάται το κόστος κτήσεως και λειτουργίας του πλοίου, αλλά και ο ελάχιστος απαιτούμενος ναύλος.

description: Luftverschmutzung verursacht hohe ökonomische Kosten durch gesundheitliche Belastungen der AnwohnerInnen, vor allem in städtischen Gebieten. Fahrbeschränkungen in Umweltzonen sollen zur Verbesserung der Luftqualität beitragen. Empirische Analysen in diesem Wochenbericht bestätigen, dass Umweltzonen verkehrsbedingte Luftverschmutzung verringern. Zusätzlich ergeben die Untersuchungen unbeabsichtigte negative Effekte auf Sekundärschadstoffe wie Ozon und auf die Luftverschmutzung in angrenzenden Gebieten. Zudem zeigen weitere Analysen basierend auf Daten des Sozio-oekonomischen Panels (SOEP) erstmals, dass Umweltzonen zwar die Gesundheit der AnwohnerInnen positiv beeinflussen, jedoch ihre Lebenszufriedenheit temporär verringern. Abhängig ist dies von den individuellen Lebensumständen; beispielsweise ist die Lebenszufriedenheit von DieselfahrerInnen und Menschen unter 65 Jahren stärker beeinträchtigt. Die Ergebnisse deuten darauf hin, dass Mobilitätsbeschränkungen und Anpassungskosten die Akzeptanz der Maßnahmen verringern. Eine verbesserte Kommunikation der gesundheitlichen Vorteile von Umweltzonen oder Transfermechanismen wie Gutscheine für die Nutzung von öffentlichen Verkehrsmitteln könnten diese Effekte abfedern.

Feasibility of supporting pointing on large wall displays using off-the-shelf consumer-grade tracking equipment
Creators: name: Muradov, Orkhan
Publisher: name: University of British Columbia
Year: 2013

description: Interactions between instructors and large projected displays in classrooms often lack cost-effective and easy-to-use solutions. Instead, instructors mostly use either a standard laser pointer, or a computer mouse or touchscreen on a laptop or tablet computer to interact with the content of their presentation slides on large screens. Our research investigates the possibility of using relatively inexpensive, consumer-grade tracking devices that can be easily installed in classrooms and inertial sensors that can be held in an instructor’s hand to support this type of interaction. Our goal was to provide more functionality than a simple laser pointer. We compared the accuracy and ease of pointing performance using our new system to a high-end research system and to a computer mouse. We used a Fitts’s law paradigm to experimentally evaluate pointing performance and accuracy. We found that our low-cost system is as accurate and as fast as the high-end research system and, somewhat surprisingly, also as accurate as a computer mouse. Because of the large size of the displays in classrooms and the small tracking volumes of most consumer-grade tracking systems, we investigated the possibility of using multiple off-the-shelf hardware units connected with each other to maximize the coverage area at the front of a classroom. We present a possible design that could be scaled to enough devices connected together to cover the front area of a classroom of almost any size. Our investigation was not conclusive. It requires additional research to prove the feasibility of our system in real classroom environments.

description: Για την παρακολούθηση των ελαττωμάτων σε μία διεργασία, η βασική υπόθεση που γίνεται είναι ότι ο αριθμός των ελαττωμάτων ανά μονάδα επιθεώρησης ακολουθεί την κατανομή Poisson και επομένως χρησιμοποιούνται τα κλασικά 𝑐 και 𝑢 διαγράμματα ελέγχου. Στις διεργασίες υψηλής απόδοσης, όπου ο ρυθμός εμφάνισης ελαττωμάτων είναι αρκετά χαμηλός, τα 𝑐 και 𝑢 διαγράμματα ελέγχου δεν είναι αποτελεσματικά, καθώς η κατανομή Poisson δεν μπορεί να προσεγγισθεί ικανοποιητικά από την κανονική, έχοντας ως αποτέλεσμα η πιθανότητα σφάλματος τύπου I που συνοδεύει τα διαγράμματα ελέγχου να είναι πολύ μεγαλύτερη από την επιθυμητή τιμή. Επιπλέον, δεν είναι δυνατόν να ανιχνευθεί περαιτέρω βελτίωση της παραγωγικής διεργασίας, αφού το κάτω όριο ελέγχου τίθεται ίσο με το μηδέν. Σε αυτές τις περιπτώσεις παρακολουθείται μια αθροιστική ποσότητα (χρόνος, μονάδες επιθεώρησης κ.α.) μέχρι την εμφάνιση 𝑟 ελαττωμάτων. Για 𝑟 = 1 η αθροιστική ποσότητα ακολουθεί την εκθετική κατανομή, ενώ για 𝑟 > 1 η αθροιστική ποσότητα ακολουθεί την Γάμμα κατανομή. Στην παρούσα διατριβή παρουσιάζονται συνολικά 79 διαγράμματα ελέγχου για την παρακολούθηση της αθροιστικής ποσότητας μέχρι την εμφάνιση 𝑟 ελαττωμάτων, όπου ορισμένα εξ αυτών μελετώνται για πρώτη φορά.

Επιπλέον, υπολογίζεται το μέσο μήκος ροής (𝐴𝑅𝐿) για όλα τα διαγράμματα ελέγχου που παρουσιάζονται στη διατριβή. Στο Κεφάλαιο 5 πραγματοποιούνται διάφορες συγκρίσεις ανάμεσα στα διαγράμματα ελέγχου που παρουσιάστηκαν με βάση το 𝐴𝑁𝑂𝑆 (average number of observations to signal) και εξάγονται συμπεράσματα αναφορικά με τα αποδοτικότερα διαγράμματα ελέγχου για την ανίχνευση διαφόρων μετατοπίσεων στη διεργασία.

description: Proton-proton collisions at sqrt{s} = 7 TeV and heavy ion collisions at sqrt{s_NN} = 2.76 TeV were produced by the LHC and recorded using the ATLAS experiment's trigger system in 2010. The LHC is designed with a maximum bunch crossing rate of 40 MHz and the ATLAS trigger system is designed to record approximately 200 of these per second. The trigger system selects events by rapidly identifying signatures of muon, electron, photon, tau lepton, jet, and B meson candidates, as well as using global event signatures, such as missing transverse energy. An overview of the ATLAS trigger system, the evolution of the system during 2010 and the performance of the trigger system components and selections based on the 2010 collision data are shown. A brief outline of plans for the trigger system in 2011 is presented

The cut-tree of large Galton-Watson trees and the Brownian CRT

Subjects: subject: Probability (math.PR)

description: Consider the edge-deletion process in which the edges of some finite tree T are removed one after the other in the uniform random order. Roughly speaking, the cut-tree then describes the genealogy of connected components appearing in this edge-deletion process. Our main result shows that after a proper rescaling, the cut-tree of a critical Galton-Watson tree with finite variance and conditioned to have size n, converges as $n\to\infty$ to a Brownian continuum random tree (CRT) in the weak sense induced by the Gromov-Prokhorov topology. This yields a multi-dimensional extension of a limit theorem due to Janson [Random Structures Algorithms 29 (2006) 139-179] for the number of random cuts needed to isolate the root in Galton-Watson trees conditioned by their sizes, and also generalizes a recent result [Ann. Inst. Henri Poincaré Probab. Stat. (2012) 48 909-921] obtained in the special case of Cayley trees.

description: Synopsis: The goal of this book is to explore the relationship between the cognitive notion of parthood and various grammatical devices expressing this concept in natural language. The monograph aims to investigate syntactic constructions and lexical categories, e.g., partitives, whole-adjectives, and multipliers, encoding different kinds of part-whole structures both in Slavic and non-Slavic languages. It is envisioned to inspire radical rethinking of the ontology of models accounting for nominal semantics. Specifically, it provides novel evidence for a mereotopological approach to meaning, i.e., a theory of wholes that captures not only parthood but also topological relations holding between parts. This evidence comes from the phenomenon of subatomic quantification, i.e., quantification over parts of referents of concrete count nouns.

description: Synopsis: This volume collects novel contributions to comparative generative linguistics that “rethink” existing approaches to an extensive range of phenomena, domains, and architectural questions in linguistic theory. At the heart of the contributions is the tension between descriptive and explanatory adequacy which has long animated generative linguistics and which continues to grow thanks to the increasing amount and diversity of data available to us. The chapters develop novel insights into a number of core syntactic phenomena, such as the structure of and variation in diathesis, alignment types, case and agreement splits, and the syntax of null elements. Many of these contributions show the influence of research by Ian Roberts and collaborators and they provide varied perspectives on current research in synchronic and diachronic comparative syntax.
Topological susceptibility on the lattice and the three-flavour quark condensate

description: We reanalyse the topological susceptibility assuming the possibility of a significant paramagnetic suppression of the three-flavour quark condensate and a correlated enhancement of vacuum fluctuations of $s\bar{s}$ pairs. Using the framework of resummed ChPT, we point out that simulations performed near the physical point, with a significant mass hierarchy between u,d and s dynamical quarks, are not able to disentangle the contributions from the quark condensate and sea $s\bar{s}$-pair fluctuations, and that simulations with three light quark masses of the same order are better suited for this purpose. We perform a combined fit of recent RBC/UKQCD data on pseudoscalar masses and decay constants as well as the topological susceptibility, and we reconsider the determination of lattice spacings in our framework, working out the consequences on the parameters of the chiral Lagrangian. We obtain Sigma(3;2 GeV)^1/3=243 \pm 12 MeV for the three-flavour quark condensate in the chiral limit. We notice a significant suppression compared to the two-flavour quark condensate Sigma(2;2 GeV)/Sigma(3;2 GeV)=1.51\pm 0.11 and we confirm previous findings of a competition between leading order and next-to-leading order contributions in three-flavour chiral series.

Intra- and supra-salt strain during gravity-driven salt tectonics on passive margins
Creators: name: Evans, Sian
Publisher: name: Imperial College London
Year: 2020

description: Ductile salt units have a profound influence on the subsequent tectono-stratigraphic evolution of sedimentary basins. The development of thin-skinned, kinematic zones of updip extension and downdip contraction, driven by the interplay between gravity gliding and gravity spreading, is well established. In detail, however, there is great complexity in the range of structural styles observed on salt-influenced passive margins, and their key controls are still not fully understood. I use 3D seismic reflection data from two salt-influenced passive margin settings (the Kwanza Basin, offshore Angola and the Levantine Basin, offshore Lebanon) to interpret their post-salt tectono-stratigraphic evolutions. I assess the relationship between sub-, intra-, and supra-salt structures, with a particular emphasis on the influence of base-salt relief and intra-salt lithological heterogeneity. A number of different tools are employed to perform this analysis, including structural restorations, strain calculations and translation measurements. Ramp syncline basins develop due to salt flow over base-salt relief and provide a record of horizontal overburden translation during gravity gliding. This record can be used to calculate rates of translation, revealing spatial and temporal variations at the basin scale in both study areas, which are linked to thick- and thin-skinned processes. On the Angolan margin, the interaction of salt flow with base-salt relief is inferred to generate local stress fields that allow synchronous extension and contraction despite closely spaced positions on the margin. On the Lebanese margin, the salt flow over large sub-salt anticlines modulates the rate of basinward translation. In both cases I show that the geometry of the base-salt surface can have an important influence on the orientation and distribution of supra-salt structures. The seismic-based interpretations are tested using physical analogue models, designed to investigate the effect of salt thickness and heterogeneity on the degree of coupling between sub- and supra-salt structures in experiments with controlled boundary conditions. These results support and integrate the seismic case studies, showing how thinner and more heterogeneous evaporite sequences are more strongly influenced by the base-salt geometry. I conclude that the interaction between salt flow and base-salt relief is a primary control on the structural development of the salt and overburden in gravity-driven systems, and this may explain some of the observed contrast in structural styles between different salt basins.

description: We provide evidence for a correlation between the presence of giant clumps and the occurrence of active galactic nuclei (AGN) in disk galaxies. Giant clumps of 10^8-9 Msun arise from violent gravitational instability in gas-rich galaxies, and it has been proposed that this instability could feed supermassive black holes (BH). We use emission line diagnostics to compare a sample of 14 clumpy (unstable) disks and a sample of 13 smoother (stable) disks at redshift z~0.7. The majority of clumpy disks in our sample have a high probability of containing AGN. Their [OIII] emission line is strongly excited, inconsistent with low-metallicity star formation alone. [NeIII] excitation is also higher. Stable disks rarely have such properties. Stacking ultra sensitive Chandra observations (4 Ms) reveals an X-ray excess in clumpy galaxies, which cannot be solely due to star formation and confirms the presence of AGN. The clumpy galaxies in our intermediate-redshift sample have properties typical of gas-rich disk galaxies rather than mergers, being in particular on the Main Sequence of star formation. This suggests that our findings apply to the physically-similar and numerous gas-rich unstable disks at z>1. Using the observed [OIII] and X-ray luminosities, we conservatively estimate that AGN hosted by clumpy disks have typical bolometric luminosities of the order of a few 10^43 erg/s, BH growth rates ~10^-2 Msun/yr, and that these AGN are substantially obscured in X-rays. This moderate-luminosity mode could be sufficient to provide a large fraction of today's BH mass over a couple of Gyr given that our observations suggest a high duty cycle (>10%), accretion bursts with higher luminosities being possible over shorter phases. The observed evolution of disk instabilities with mass and redshift could explain the simultaneous downsizing of star formation and of BH growth.

description: Im Verlauf des 20. Jahrhunderts haben Regierungen die Regulierung von Mietpreisen häufig eingesetzt, um insbesondere in Krisenzeiten auch bei knappem Wohnraum Mieten bezahlbar zu halten. Bisherige Forschung hat gezeigt, dass diese Regulierung allerdings mit gesamtgesellschaftlichen Wohlstandsverlusten, Misallokation am Markt und anderen unerwünschten Nebeneffekten wie sinkendem Wohnungsangebot und niedrigerer Mobilität verbunden ist. Dabei wurde allerdings nur selten untersucht, welchen Effekt die Regulierung von Mietpreisen auf ökonomische Ungleichheit hat. Weltweit lässt sich seit den 1980er Jahren ein Wiederanstieg der Einkommensungleichheit beobachten. Während sich bisherige Erklärungen für diese Entwicklung auf das Verhältnis von Kapital- und Lohnwachstum und sozialpolitische Maßnahmen fokussierten, argumentiert dieser Beitrag, dass die bestehenden Erklärungen um eine Wohnungsdimension ergänzt werden sollten. Anhand einer Zeitreihenanalyse wird untersucht, welchen Einfluss Mietpreisregulierung auf Einkommensungleichheit ausübt. Dabei zeigt sich: Die Regulierung der Mieten reduziert die in dem Gini-Koeffizienten ausgedrückte soziale Ungleichheit signifikant und verringert das Vermögens-Nationaleinkommens- Verhältnis. Diese Effekte sind stärker, je strenger die ergriffenen Maßnahmen sind. Mikro-Daten aus verschiedenen Ländern legen nahe, dass die unteren Einkommensgruppen einen größeren Teil ihres Einkommens für die Miete ausgeben, während höhere Einkommensgruppen einen größeren Teil ihrer Einnahmen durch Vermietung erzielen. Werden die Mieten durch staatliche Maßnahmen gesenkt, steigen kurzfristig die verfügbaren Einkommen der unteren Einkommensgruppen, während der Einkommensanteil der bestverdienenden zehn Prozent kurzfristig sinkt. Es ist eine Frage der politischen Bewertung, wie diese Effekte und die bereits bekannten Einflüsse von Mietpreisregulierung auf gesamtgesellschaftlichen Wohlstand und den Mietmarkt abgewägt werden.

Integrating building-level and campus-level data

description: Integrating building design data (in the form of Building Information Models - BIMs) and 3D City Models is a promising solution to retrieving both detailed building information and exploring the relationships among building components and buildings in a city area. It could also help to facilitate decision making in building facility management and maintenance operations. Among other challenges, performing such an integration is difficult because BIMs and 3D city models vary in both semantic and geometric representations. Our first attempt was to try to convert the BIM into the city model, but the results were very disappointing. It is infeasible to convert every necessary component in the BIM into the city model, and the converted files cannot be visualized by the current city model applications. Next, we implemented a data integration system to incorporate information from both models. We used a novel approach to apply arithmetic expressions to express the overlapping information, not only for the semantic representation, but also on the geometric representation of the building components. This approach improved query answering on components from both models. Finally, we describe future challenges that will be needed to improve the accuracy of our current approach.

description: Due to the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic, a large number of elective knee replacement procedures had to be postponed in both early and late 2020 in most western countries including Germany and the UK. It is unknown how public interest and demand for total knee arthroplasties was affected. Public interest in knee pain, knee osteoarthritis and knee arthroplasty in Germany and the UK was investigated using Google Trend Analysis. In addition, we monitored for changes in patient composition in our outpatient department. As of early March in Germany and of late March in the UK, until the lockdown measures, a 50 to 60% decrease in relative search frequency was observed in all categories investigated compared to the beginning of the year. While public interest for knee pain rapidly recovered, decreased interest for knee osteoarthritis and replacement lasted until the easing of measures. Shortly prior to and during the first lockdown mean search frequency for knee replacement was significantly decreased from 39.7% and 36.6 to 26.9% in Germany and from 47.7% and 50.9 to 23.7% in the UK (Germany: p = 0.022 prior to lockdown, p < 0.001 during lockdown; UK: p < 0.0001 prior to and during lockdown). In contrast, mean search frequencies did not differ significantly from each other for any of the investigated time frames during the second half of 2020 in both countries. Similarly, during the first lockdown, the proportion of patients presenting themselves to receive primary knee arthroplasty compared to patients that had already undergone knee replacement declined markedly from 64.7% to 46.9%. In contrast, patient composition changed only marginally during the lockdown measures in late 2020 in both Germany and the UK. We observed a high level of public interest in knee arthroplasty despite the ongoing pandemic. The absence of a lasting decline in interest in primary knee arthroplasty suggests that sufficient symptom reduction cannot be achieved without surgical care for a substantial number of patients.

description: Health-related quality of life (HRQL) among migrant populations can be associated with acculturation (i.e., the process of adopting, acquiring and adjusting to a new cultural environment). Since there is a lack of longitudinal studies, we aimed to describe HRQL changes among adults of Turkish descent living in Berlin and Essen, Germany, and their association with acculturation. Participants of a population-based study were recruited in 2012-2013 and reinvited six years later to complete a questionnaire. Acculturation was assessed at baseline using the Frankfurt acculturation scale (integration, assimilation, separation and marginalization). HRQL was assessed at baseline (SF-8) and at follow-up (SF-12) resulting in a physical (PCS) and mental (MCS) sum score. Associations with acculturation and HRQL were analyzed with linear regression models using a time-by-acculturation status interaction term. In the study 330 persons were included (65% women, mean age ± standard deviation 43.3 ± 11.8 years). Over the 6 years, MCS decreased, while PCS remained stable. While cross-sectional analyses showed associations of acculturation status with both MCS and PCS, temporal changes including the time interaction term did not reveal associations of baseline acculturation status with HRQL. When investigating HRQL in acculturation, more longitudinal studies are needed to take changes in both HRQL and acculturation status into account.
Inverted sfermion mass hierarchy and the Higgs boson mass in the MSSM

description: It is shown that MSSM with first two generations of squarks and sleptons much heavier than the third one naturally predicts the maximal stop mixing as a consequence of the RG evolution, with vanishing (or small) trilinear coupling at the high scale. The Higgs boson is generically heavy, in the vicinity of 125 GeV. In this inverted hierarchy scenario, motivated by the supersymmetric FCNC problem and models for fermion masses based on horizontal symmetries, the mass of the lightest stop is O(0.5) TeV and of gluino - O(2-3) TeV. The LSP can be either higgsino or bino or a mixture of both and it can be a good dark matter candidate.

description: The parity doublet of 1⁺/1⁻ states of Ne⁻²⁰ at 11.26 MeV excitation energy is one of the best known test cases to study the weak part of the nuclear Hamiltonian. The feasibility of parity violation experiments depend on the effective nuclear enhancement factor (RN/|E(1⁺) − E(l⁻)|) which amplifies the impact of the matrix element of the weak interaction on observables indicating parity mixing. An extreme large value of Rn/|E(1⁺) − E(l⁻)| = (670 ± 7000) MeV⁻¹ was reported for the doublet in ²⁰Ne. The large uncertainty depends amongst others on the large uncertainty of |E(1⁺) − E(l⁻)| = 7.7±5.5 keV of the parity doublet. Nuclear resonance fluorescence (NRF) experiments with linearly and circularly polarized photon beams were performed at the High Intensity Gamma-Ray Source at Duke University, Durham, NC, USA, to determine the energy difference of the parity doublet with higher precision. The different angular distributions for 0⁺ → 1⁻ → 0⁺ and 0⁺ → 1⁺ → 0⁺ NRF cascades in polarized γ-ray beams were used to determine the energy difference of the parity doublet to 2.9(13) keV.
