description: Female carriers of BRCA1/2 gene mutations are at an increased lifetime risk for breast and ovarian cancers. They are recommended to undergo risk-reducing surgery, including bilateral salpingo-oophorectomy (RR-BSO), upon completion of childbearing. RR-BSO surgery decreases morbidity and mortality but results in early menopause. Menopausal hormone therapy (MHT) is under-utilized despite being shown as safe for carriers. We aim to evaluate the factors associated with decision-making regarding MHT use following RR-BSO in healthy BRCA mutation carriers. Female carriers aged <50 years who underwent RR-BSO and were followed in a multidisciplinary clinic completed online multiple-choice and free-text questionnaires. A total of 142 women met the inclusion criteria and filled the questionnaire: 83 were MHT users and 59 were non-users. MHT users underwent RR-BSO earlier than non-users (40.82 ± 3.91 vs. 42.88 ± 4.34; p < 0.0001). MHT usage was positively associated with MHT explanation (odds ratio 4.318, 95% confidence interval [CI] [1.341–13.902], p = 0.014), and knowledge regarding the safety of MHT and its effects on general health (odds ratio 2.001, 95% CI [1.443–2.774], p < 0.0001). MHT users and non-users retrospectively evaluated their comprehension of RR-BSO consequences as significantly lower than before surgery (p < 0.001). Post-RR-BSO outcomes, including the effects on women’s quality of life and its possible mitigation through MHT use, need to be addressed pre surgery by healthcare providers.

description: Large-angle twisted bilayer graphene (tBLG) is known to be electronically decoupled due to the spatial separation of the Dirac cones corresponding to individual graphene layers in the reciprocal space. This mechanism also leads to the decoupling in multilayer graphene systems including twisted double bilayer graphene, which are just a small subset of a broad class of systems consisting of graphene layers and other materials, decoupled by the twist or separated by dielectrics. For the former, the close spacing between the layers causes strong capacitive coupling, opening possibilities for new applications in atomically thin devices. Here, we present a self-consistent quantum capacitance model for the electrostatics of decoupled graphene layers, and further generalize it to deal with decoupled tBLG at finite magnetic field and large-angle twisted double bilayer graphene at zero magnetic field. We probe the capacitive coupling through the conductance, showing good agreement between simulations and experiments for all these systems considered. Our model can be extended to systems composed of decoupled graphene multilayers as well as non-graphene systems, opening a new realm of quantum-capacitively coupled materials.

description: The Purcell factor quantifies the change of the radiative decay of a dipole in an electromagnetic environment relative to free space. Designing this factor is at the heart of photonics technology, striving to develop ever smaller or less lossy optical resonators. The Purcell factor can be expressed using the electromagnetic eigenmodes of the resonators, introducing the notion of a mode volume for each mode. This approach allows to use an analytic treatment, consisting only of sums over eigenmode resonances, a so-called spectral representation. We show in the present work that the expressions for the mode volumes known and used in literature are only approximately valid for modes of high quality factor, while in general they are incorrect. We rectify this issue, introducing the exact normalization of modes. We present an analytic theory of the Purcell effect based on the exact mode normalization and resulting effective mode volume. We use a homogeneous dielectric sphere in vacuum, which is analytically solvable, to exemplify these findings.

description: Spacecrafts continuously need for low cost and weight sensor easy to integrate in a plug-in approach and capable to improve platforms versatility while reducing integration time and complexity. This is particularly true for the new generation of small and micro satellites to be launched in constellation and formation. Controlling small satellites cooperation and protecting the space assets from debris are two important issues of current and future missions. The cost reduction and safety of space missions is a key issue for further expand European leadership in the Earth Observation and Communication sectors. The POLIFEMO (Panoramic Multifunctional Sensor for Small/Micro Satellite) is a unique solution for an integrated sensor capable to replace by one single unit the functions of Sun sensor, Earth sensor and Star tracker and, additionally, providing external situational awareness. POLIFEMO is based on an innovative lens with a very wide angle (with a hyper-hemispheric field of view) able to look at a field of view of 360 in azimuth (panoramic omnidirectional lens) and 270 in elevation (hyper-hemispheric capabilities), designed and patented by the Italian National Institute for Astrophysics (INAF). POLIFEMO, with that extremely high field of view and unique imaging detection capability, results in a small, low weight, low cost and reliable (no moving part, potentially failure point) space sensor. It is unique in the market of space sensors and suitable for many spaces and non-space missions (e.g., communication, weather, imaging, surveillance, deep space but also UAV/HAP). Progetti Speciali Italiani s.r.l., a SME active in developing microsatellite and space applications, has set up, during the phase 1 project, a very experienced team of engineering and commercial specialists for carrying on the proposed project. University of Napoli (Parthenope) is expert on developing satellites star trackers solutions. This paper reports a summary extracted from a more detailed BP (Doc: ECSME-PSI-POLIFEMO-BP-2016) which has been prepared within the EU-H2020 contract framework. The full BP is available on request.

description: The initial idea from which we started was to provide users with a tool to be able to easily recover their data previously stored into a tape library. The project structure then evolved into something more complex and led to the development of a VOSpace implementation compliant with the IVOA VOSpace specification[1]. The current VOSpace allows users to store and retrieve data using local, hot and cold storage points: • a local storage point stores data uploaded through the VOSpace User Interface • hot and cold storage points store data uploaded asynchronously using a transfer node. Both local and hot storage points rely on the Lustre[2] parallel file system. Retrieving data from a local storage point is immediate since users just have to launch a download, so this operation is synchronous. Conversely, data stored into hot or cold storage points must be retrieved asynchronously. More precisely, the VOSpace creates symbolic links to make data available from hot storage points. In this way there is no need to perform a copy. Data stored into cold storage points (e.g. a tape library), instead, must be recalled. This report describes all the operations and the functionalities of the current INAF VOSpace implementation from the user point of view.

description: The random walk loop soup is a Poissonian ensemble of lattice loops; it has been extensively studied because of its connections to the discrete Gaussian free field, but was originally introduced by Lawler and Trujillo Ferreras as a discrete version of the Brownian loop soup of Lawler and Werner, a conformally invariant Poissonian ensemble of planar loops with deep connections to conformal loop ensembles (CLEs) and the Schramm-Loewner evolution (SLE). Lawler and Trujillo Ferreras showed that, roughly speaking, in the continuum scaling limit, ``large'' lattice loops from the random walk loop soup converge to ``large'' loops from the Brownian loop soup. Their results, however, do not extend to clusters of loops, which are interesting because the connection between Brownian loop soup and CLE goes via cluster boundaries. In this paper, we study the scaling limit of clusters of ``large'' lattice loops, showing that they converge to Brownian loop soup clusters. In particular, our results imply that the collection of outer boundaries of outermost clusters composed of ``large'' lattice loops converges to CLE.

description: Electrical power is the major constraint to interplanetary survival and exploration. Long-stay missions present the crew with ~540 days to explore the planet's surface and a human exploration team on Mars would be ~25 times more scientifically productive than a robotic rover. It is worthwhile to explore options that can enhance human exploration capability but traditional rovers must return to base to recharge, limiting their range. A rover with an on-board fission reactor does not need to return to base to recharge and it can enable humans to visit multiple sites in one mission. It was found that it is feasible to add a shield thick enough to keep the crew safe from the reactor. The required shielding thickness did not change substantially with different reactor power output levels, nor did it change with varying distances from the reactor core. It was found that the shape of the shield greatly affected its overall mass.

description: Molecular structures of four 6-chloro-coumarins have been optimized using DFT/B3LYP method. The energy of the HOMO and LUMO has been predicted. Lattice energy analysis (based on CLP-PIXEL module) in case of each structure indicates that the crystal packing stability is mainly derived by C–H…O and π…π type interactions. Besides this, the intermolecular interactions of the type C–H…Cl, C–H…π, C–Cl…π and C–Cl…O also exist in the crystal structures. Quantitative analysis of each intermolecular interaction using 3D-Hirshfeld surfaces and corresponding 2D-fingerprint has been carried out.

description: We derive a general expression that quantifies the total entanglement production rate in continuous variable systems, where a source emits two entangled Gaussian beams with arbitrary correlators.This expression is especially useful for situations where the source emits an arbitrary frequency spectrum,e.g. when cavities are involved. To exemplify its meaning and potential, we apply it to a four-mode optomechanical setup that enables the simultaneous up- and down-conversion of photons from a drive laser into entangled photon pairs. This setup is efficient in that both the drive and the optomechanical up- and down-conversion can be fully resonant.

description: Excerpts from the report Summary: Research on the international aspects of production and marketing of winter fruits and vegetables shows that Mexico--with an increase of imports from $18,907,000 in 1956 to $99,596,000 in 1967--has become an important source of fruits and vegetables for the United States. Traditionally, winter produce for the U.S. market came primarily from Florida, California, and Texas. Mexico, in recent years, has moved ahead of California and Texas as a major supplier of vegetables, and has the potential of becoming the dominant supplier. Supplies of winter produce began to come to the United States from Mexico and the Caribbean area in the early 1900's. Prior to the 1950's, domestic producers apparently did not look upon these supplies as a threat. However, by the end of the 1950's, producers began to feel alarm over Mexico's growing share of the U.S. vegetable market. The loss of Cuba as a production base, termination of the special provisions of the Immigration and Nationality Act admitting foreign seasonal agricultural workers (bracero program), and development of transportation and irrigation facilities in western Mexico contributed to Mexico's growth as a supplier of winter produce. California and Texas had climate disadvantages which quickly forced them into minor positions as winter supply areas for certain types of produce after Mexico began to expand its output. The Florida vegetable industry began to feel pressure from Mexican imports around the mid-sixties.

description: This is a short review of string cosmology. We wish to connect string-scale physics as closely as possible to observables accessible to current or near-future experiments. Our possible best hope to do so is a description of inflation in string theory. The energy scale of inflation can be as high as that of Grand Unification (GUT). If this is the case, this is the closest we can possibly get in energy scales to string-scale physics. Hence, GUT-scale inflation may be our best candidate phenomenon to preserve traces of string-scale dynamics. Our chance to look for such traces is the primordial gravitational wave, or tensor mode signal produced during inflation. For GUT-scale inflation this is strong enough to be potentially visible as a B-mode polarization of the cosmic microwave background (CMB). Moreover, a GUT-scale inflation model has a trans-Planckian excursion of the inflaton scalar field during the observable amount of inflation. Such large-field models of inflation have a clear need for symmetry protection against quantum corrections. This makes them ideal candidates for a description in a candidate fundamental theory like string theory. At the same time the need of large-field inflation models for UV completion makes them particularly susceptible to preserve imprints of their string-scale dynamics in the inflationary observables, the spectral index $n_s$ and the fractional tensor mode power $r$. Hence, we will focus this review on axion monodromy inflation as a mechanism of large-field inflation in string theory.

description: Piezoelectric energy harvesters (PEHs) have the potential to power low-power electronic devices and can advance, self-powered, autonomous electronics to the next level. Conventional ceramic-based piezoelectrics have various properties such as fragility, rigidity, toxicity, high density, and lack of design flexibility which limit their use in more flexible environments. A ton of research has been carried out and published on novel piezomaterials, their transduction mechanisms, analytical models, and electrical circuits to improve various aspects of PEHs. Among these materials, studies on polymeric cellular (or foamed) ferroelectrets or piezoelectrets as PEHs have grown significantly since their discovery. Also, very limited or short reviews are available covering only few aspects. There is a necessity of recognizing their past and present advances in their various generation technology and polymer systems. Herein, a broader review of almost all conventional and recent polymeric foam-based piezoelectrics for PEH applications is summarized. These cellular polymer piezoelectric systems either in bulk, composite, layered, or film form can be fabricated, and depending on the application and conditions, different polymers groups, mainly, polyolefins, polyester, fluoropolymer, and others, are considered. Their applications and future perspectives are also presented and discussed.
Contact potential instability in the path-integral description of itinerant ferromagnetism

description: It has long been predicted that a two-component non-localized Fermi gas will exhibit spontaneous polarization for sufficiently strong repulsive interactions, a phenomenon which is called itinerant ferromagnetism. Recent experiments with ultracold atomic gases have reached the interaction strength for which theoretical models have predicted the occurrence of the normal-to-itinerant-ferromagnetic phase transition, but so far this transition has not been observed. The instability of the repulsive branch of the Feshbach resonance prevents the formation of the itinerant ferromagnetic state, but it is not clear whether this is the only instability impeding its experimental realization. In this article, we use the path-integral formalism with density fields in the Hubbard-Stratonovich transformation to study the stability of a homogeneous two-component Fermi gas with contact interactions. Within the saddle-point approximation we show that none of the extrema of the action are minima, meaning all extrema are unstable to small density fluctuations. This implies a more general mechanical instability of the polarized (itinerant ferromagnetic) and normal states of the system in the path-integral formalism. We find that it is important to consider the stability of the system when studying itinerant ferromagnetism. Since (mechanical) stability may be influenced by the details of the interaction potential, we suggest the use of a more realistic potential than the contact potential in future theoretical descriptions.

description: The inclusive jet cross-section is measured in proton-proton collisions at a centre-of-mass energy of 7 TeV using a data set corresponding to an integrated luminosity of 4.5 fb$^{-1}$ collected with the ATLAS detector at the Large Hadron Collider in 2011. Jets are identified using the anti-$k_t$ algorithm with radius parameter values of 0.4 and 0.6. The double-differential cross-sections are presented as a function of the jet transverse momentum and the jet rapidity, covering jet transverse momenta from 100 GeV to 2 TeV. Next-to-leading-order QCD calculations corrected for non-perturbative effects and electroweak effects, as well as Monte Carlo simulations with next-to-leading-order matrix elements interfaced to parton showering, are compared to the measured cross-sections. A quantitative comparison of the measured cross-sections to the QCD calculations using several sets of parton distribution functions is performed.

description: We use extensive computer simulations to probe local thermodynamic equilibrium (LTE) in a quintessential model fluid, the two-dimensional hard-disks system. We show that macroscopic LTE is a property much stronger than previously anticipated, even in the presence of important finite size effects, revealing a remarkable bulk-boundary decoupling phenomenon in fluids out of equilibrium. This allows us to measure the fluid's equation of state in simulations far from equilibrium, with an excellent accuracy comparable to the best equilibrium simulations. Subtle corrections to LTE are found in the fluctuations of the total energy which strongly point out to the nonlocality of the nonequilibrium potential governing the fluid's macroscopic behavior out of equilibrium.

description: Excerpt from the report Summary: This study of human resources in a 10-county area of the Northeast Coastal Plain of South Carolina disclosed severe and persistent problems--problems that preclude easy or quick solutions. Implied needs of the rural population are more jobs; improved housing; greater educational opportunities for youth; training, retraining, and job placement services for adults; and programs of public assistance. The success of programs to provide these needs will depend largely on the attitudes of the area's rural inhabitants, their capacity for self-improvement, and their willingness to accept change. Although the results of the study relate specifically to the 10-county area, this area is believed to be typical of the rural environment of the broad Coastal Plain Region
The impact of energy conservation in transport models on the $π^-/π^+$ multiplicity ratio in heavy-ion collisions and the symmetry energy

description: The charged pion multiplicity ratio in intermediate energy central heavy-ion collisions has been proposed as a suitable observable to constrain the high density dependence of the isovector part of the equation of state, with contradicting results. Using an upgraded version of the Tübingen QMD transport model, which allows the conservation of energy at a local or global level by accounting for the potential energy of hadrons in two-body collisions and leading thus to particle production threshold shifts, we demonstrate that compatible constraints for the symmetry energy stiffness can be extracted from pion multiplicity and elliptic flow observables. Nevertheless, pion multiplicities are proven to be highly sensitive to the yet unknown isovector part of the in-medium $Δ$(1232) potential which hinders presently the extraction of meaningful information on the high density dependence of the symmetry energy. A solution to this problem together with the inclusion of contributions presently neglected, such as in-medium pion potentials and retardation effects, are needed for a final verdict on this topic.

Rényi and Tsallis formulations of noise-disturbance trade-off relations

Subjects: subject: Quantum Physics (quant-ph)

description: We address an information-theoretic approach to noise and disturbance in quantum measurements. Properties of corresponding probability distributions are characterized by means of both the Rényi and Tsallis entropies. Related information-theoretic measures of noise and disturbance are introduced. These definitions are based on the concept of conditional entropy. To motivate introduced measures, some important properties of the conditional Rényi and Tsallis entropies are discussed. There exist several formulations of entropic uncertainty relations for a pair of observables. Trade-off relations for noise and disturbance are derived on the base of known formulations of such a kind.

Notker der Deutsche als Kosmograph: Ein St. Galler Erd- und Himmelsglobus um 1015

description: Die mögliche Existenz geographischer Abbildungen auf frühmittelalterlichen Globen ist zu überdenken. Die jüngste Forschung in diesem Feld stützt sich auf jüngere Befunde aus der germanistischen Mediävistik, die in der Kartographiegeschichte bislang noch kaum beachtet wurden. Konkret handelt es sich um die neu interpretierte Übersetzung eines kosmographischen Exkurses im Boethius-Kommentar von Notker Labeo (um 950–1022) aus dem Althochdeutschen (Cod. Sang. 825). Im Rahmen von Erläuterungen zum Wert des irdischen Ruhmes macht Notker einen ausführlichen astronomisch-geographischen Exkurs über gut zwei Seiten. Um diese kosmographischen Betrachtungen den St. Galler Klosterschülern zu verdeutlichen, verweist er auf einen Globus, der «jüngst» unter der Ägide des Abtes Purchart II. (1001-1022) gebaut worden sei. Als Schulvorsteher und engagierter Lehrer, der dem Quadrivium nachweislich zugeneigt war, kommt Notker selbst als spiritus rector eines solchen kosmographischen Globusbaus infrage. Er macht wenige, aber sehr aussagekräftige Bemerkungen zum Aussehen und zur Funktionsweise des Globus. Seine einzigartige Auslegung zur Ausdehnung der Ökumene, die sich auch auf dem Globus wiederfand, macht die Konzeption durch Notker sogar sehr wahrscheinlich. Das Untersuchungsobjekt ist nicht zu verwechseln mit dem mittlerweile als «St. Galler Globus» bekannten Modell von Tilemann Stella (1576). Allerdings gibt es hinsichtlich des kosmographischen Ansatzes erstaunliche Parallelen.

description: In this work, we used the design strategy “doped nonpolar polymers” and synthesized the polyurethane elastomers (PUEs) by doping with highly polar aromatic molecules such as benzoic acid (BA), 4(para)-nitro-benzoic acid (PNBA), and 3, 5-dinitro- benzoic acid (3, 5-DNBA) by using the solution casting method. The effect of each molecule in three different weight percentages 2%, 4%, and 6% on electrical and thermo-mechanical properties of the material has studied. Experiments were carried out to determine electrical properties such as DC volume resistivity, dielectric constant, and loss factor. DMA and DSC measurements were done to assess thermo mechanical properties. Also, thermal conductivity measurement was carried out and a strong nitro group and doping percentage dependent results have been observed. A comparative analysis of the effect on the said properties was done among the doped and undoped PUEs.

description: Excerpt from the report Summary: A total of 4,850 corporate county units operating about 13 million acres of land were found in the 25 States included in this report. Such units represented less than 1 percent of all commercial farms and 5 percent of the land in farms in these States. About one-third of the total number and two-thirds of the total acreage in corporate county units was in 2 States--Florida and Texas. In Florida, 9 percent of the total number of commercial farms and 31 percent of the land in farms were corporate. Several States in the Northeast also had a relatively high proportion of their commercial farms operated by corporations.

description: Real-time dynamics in a quantum many-body system are inherently complicated and hence difficult to predict. There are, however, a special set of systems where these dynamics are theoretically tractable: integrable models. Such models possess non-trivial conserved quantities beyond energy and momentum. These quantities are believed to control dynamics and thermalization in low dimensional atomic gases as well as in quantum spin chains. But what happens when the special symmetries leading to the existence of the extra conserved quantities are broken? Is there any memory of the quantities if the breaking is weak? Here, in the presence of weak integrability breaking, we show that it is possible to construct residual quasi-conserved quantities, so providing a quantum analog to the KAM theorem and its attendant Nekhoreshev estimates. We demonstrate this construction explicitly in the context of quantum quenches in one-dimensional Bose gases and argue that these quasi-conserved quantities can be probed experimentally.

description: In the context of Epidemic Intelligence, many Event-Based Surveillance (EBS) systems have been proposed in the literature to promote the early identification and characterization of potential health threats from online sources of any nature. Each EBS system has its own surveillance definitions and priorities, therefore this makes the task of selecting the most appropriate EBS system for a given situation a challenge for end-users. In this work, we propose a new evaluation framework to address this issue. It first transforms the raw input epidemiological event data into a set of normalized events with multi-granularity, then conducts a descriptive retrospective analysis based on four evaluation objectives: spatial, temporal, thematic and source analysis. We illustrate its relevance by applying it to an Avian Influenza dataset collected by a selection of EBS systems, and show how our framework allows identifying their strengths and drawbacks in terms of epidemic surveillance.
The Synthesis And Study Of A Novel Class Of Reactive Alkoxypolysiloxane Polymers
Creators: name: Sulemanji, Shees
Publisher: name: London South Bank University
Year: 1985

description: The objective of this work has been the synthesis and study of a novel class of reactive alkoxypolysiloxane polymers. Reviews are presented of the chemistry of organosiloxanes with particular reference to polymerisation reactions, and the preparation and properties of the organoalkoxysilanes. A study has been carried out on the base catalysed alcoholysis of a model polymethylhydrogensiloxane polymer (CH,), Si +0SiMeH?1,4 O0-Si(CH,),: with the following alcohols ROH where R = methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl and halo-alcohols X-CH,.CH,OH where X = F, Cl, Br and I. The alcoholysis rates have been quantitatively determined by the use of a modified Van Slyke gas burette technique. Relative rates have been interpreted in terms of the electronic and steric contributions of the R and X groups. The thermal stability of the above polymers has been studied, using thermogravimetric (TGA) techniques, in air and nitrogen, and mechanisms postulated for the degradation processes. Copolymers of methylhydrogensiloxanes and dimethylsiloxanes have been prepared, using acid clay catalyst systems. These have been alkoxylated with the range of alcohols described above, and the thermal stability (by TGA) studied, in air and nitrogen, of the methoxy, ethoxy and halogenated copolymers and appropriate mechanisms postulated. Gellation studies have been carried out on the methoxylated copolymers, using a range of condensation catalysts under various atmospheric humidities. The physical properties, and crosslink densities have been measured on a range of room temperature vulcanising (RTV) elastomers produced from the alkoxylated copolymers.

description: Recently it was shown that in QCD-like theories with $N_f > N$, where $N_f$ is the number of light flavors and $N$ is the number of colors, there are correlation functions that vanish in perturbation theory and at short distances receive dominant, calculable contributions from small instantons. Here we extend the set of such objects to theories with $N_f = N$, which includes real QCD, and discuss their application as a calibration of lattice computations at small quark mass. We revisit the related issue of the $u$ quark mass and its additive renormalization by small instantons, and discuss an alternative test of $m_u=0$ on the lattice.
