Universal extra dimension: Violation of Kaluza-Klein parity

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The minimal Universal Extra Dimension (mUED) model respects the Kaluza-Klein (KK) parity $(-1)^n$, where $n$ is the KK number. However, it is possible to have interactions located at only one of the two fixed points of the $S_1/\ztwo$ orbifold. Such asymmetric interactions violate the KK parity. This kills the cold dark matter component of UED but also removes the upper bound on the inverse compactification radius, and thus non-observation of the KK excitations even at the Large Hadron Collider does not necessarily invalidate the model. Apart from the decay of the lightest $n=1$ KK excitation, this leads to collider signals which are markedly different from those in the mUED scenario. The phenomenological consequences of such KK-parity violating terms are explored.

PRUNE-1 DRIVES THE RECRUITMENT AND THE POLARIZATION OF TUMOUR-ASSOCIATED MACROPHAGES (TAMS) PREPARING THE SOIL FOR LUNG METASTASES IN TRIPLE NEGATIVE BREAST CANCER

description: Tumour microenvironment is a complex network of cells, including immune cells, with a role in tumorigenesis and metastatic spread. Among the immune cells, M2-polarized Tumour-Associated-Macrophages (M2-TAMs) show immunosuppressive activities by expressing inflammatory molecules, thus promoting tumorigenesis. Triple-Negative Breast Cancer (TNBC), lacking both hormone receptors (i.e. Progesterone Receptor [PgR] and Estrogen Receptor [ER]) and Human Epidermal growth factor Receptor 2 (HER2), is associated with poor prognosis and high probability of distant metastases. In TNBC, a large number of infiltrating M2-TAMs is positively correlated to higher risk of metastases and lower rates of Disease-Free Survival? (EFS) and Overall Survival (OS). Prune-1 belongs to DHH (Asp-His-His) phosphoesterase superfamily with an exopolyphosphatase activity. The overexpression of Prune-1 is correlated with metastases and poor prognosis in several tumours including Breast Cancer (BC). Prune-1 was also found to induce Epithelial-Mesenchimal-Transition (EMT) and metastatic dissemination throught the enhancement of canonical TGF-? signaling by counterbalancing its inhibition operated by NDPK-A. Further evidences suggested that lung cancer progression is driven by Prune-1 through the canonical WNT signaling pathway in both autocrine and paracrine manner via Wnt3a cytokine secretion, thus suggesting a potential role for Prune-1 also in extracellular environment. Here, we identified Prune-1 protein as overexpressed in TNBC patients and positively correlated to lynphnode metastases, inflammatory pathways and infiltrating M2-TAMs (CD68+/CD163+). Furthermore, we developed a Genetically Engineered Mouse Model (GEMM) of metastatic TNBC over-expressing both Prune-1 and Wnt-1 in mammary glands (MMTV-Prune1/Wnt1). We found Prune-1 to recruit TAMs and to enhance their polarization toward a pro-tumorigenic M2-phenotype in the tumour microenvironment, thus promoting lung metastases in this GEMM. We also show that Prune-1 takes part to the communication between TNBC cells and TAMs through intracellular pathways activation (i.e., TGF-b and NF-kB), but also in a paracrine manner by inducing the secretion of inflammatory cytokines (e.g., IL-17F and IL-28) and modulating the exosome protein contents. Finally, we found an anti-Prune-1 drug (AA7.1) with the ability to reduce the primary tumour growth by reducing the percentage of M2-TAMs in orthotopic xenograft immunocompetent models of TNBC. In conclusion, our GEMM of metastatic TNBC driven by Prune-1 will be a useful source for future immunotherapy pre-clinical trials targeting M2-polarized TAMs within the tumour microenvironment to inhibit distant metastases in TNBC with poor prognosis.

description: In order to gain a better understanding of the state space of programs, with the aim of making their verification more tractable, models based on directed topological spaces have been introduced, allowing to take in account equivalence between execution traces, as well as translate features of the execution (such as the presence of deadlocks) into geometrical situations. In this context, many algorithms were introduced, based on a description of the geometrical models as regions consisting of unions of rectangles. We explain here that these constructions can actually be performed directly on the syntax of programs, thus resulting in representations which are more natural and easier to implement. In order to do so, we start from the observation that positions in a program can be described as partial explorations of the program. The operational semantics induces a partial order on positions, and regions can be defined as formal unions of intervals in the resulting poset. We then study the structure of such regions and show that, under reasonable conditions, they form a boolean algebra and admit a representation in normal form (which corresponds to covering a space by maximal intervals), thus supporting the constructions needed for the purpose of studying programs. All the operations involved here are given explicit algorithmic descriptions.

description: Clocked Cubical Type Theory is a new type theory combining the power of guarded recursion with univalence and higher inductive types (HITs). This type theory can be used as a metalanguage for synthetic guarded domain theory in which one can solve guarded recursive type equations, also with negative variable occurrences, and use these to construct models for reasoning about programming languages. Combining this with HITs allows for the use of type constructors familiar from set-theory based approaches to semantics, such as quotients and finite powersets in these models. In this paper we show how to reason about the combination of finite non-determinism and recursion in this type theory. Unlike traditional domain theory which takes an ordering of programs as primitive, synthetic guarded domain theory takes the notion of computation step as primitive in the form of a modal operator. We use this extra intensional information to define two guarded recursive (finite) powerdomain constructions differing in the way non-determinism interacts with the computation steps. As an example application of these we show how to prove applicative similarity a congruence in the cases of may- and must-convergence for the untyped lambda calculus with finite non-determinism. Such results are usually proved using operational reasoning and Howe's method. Here we use an adaptation of a denotational method developed by Pitts in the context of domain theory.

description: Fully packed loop models describe the statistics of closely packed nested polygons on the square lattice. Many exact results can be obtained for these models, even for finite geometries, using their close relationship to alternating-sign matrices and the solvable six-vertex and O(n=1) lattice models. Some results for the exact partition function of fully packed loop models on various finite geometries are briefly reviewed, as well as the well-known order-disorder bulk phase transition present in these models. A detailed study is presented of the distribution of boundary nests of polygons in fully packed loop models with mirror or rotational symmetry. The probability distribution function of such nests, as well as the average number of nests, are obtained analytically, albeit conjecturally. It is further shown that fully packed loop models undergo another phase transition as a function of the boundary nest fugacity. At criticality, we derive a scaling form for the nest distribution function which displays an unusual non-Gaussian cubic exponential behaviour.

description: This PhD thesis addresses the topic of large-scale interactions between climate and marine biogeochemistry. To this end, centennial simulations are performed under present and projected future climate conditions with a coupled ocean-atmosphere model containing a complex marine biogeochemistry model. The role of marine biogeochemistry in the climate system is first investigated. Phytoplankton solar radiation absorption in the upper ocean enhances sea surface temperatures and upper ocean stratification. The associated increase in ocean latent heat losses raises atmospheric temperatures and water vapor. Atmospheric circulation is modified at tropical and extratropical latitudes with impacts on precipitation, incoming solar radiation, and ocean circulation which cause upper-ocean heat content to decrease at tropical latitudes and to increase at middle latitudes. Marine biogeochemistry is tightly related to physical climate variability, which may vary in response to internal natural dynamics or to external forcing such as anthropogenic carbon emissions. Wind changes associated with the North Atlantic Oscillation (NAO), the dominant mode of climate variability in the North Atlantic, affect ocean properties by means of momentum, heat, and freshwater fluxes. Changes in upper ocean temperature and mixing impact the spatial structure and seasonality of North Atlantic phytoplankton through light and nutrient limitations. These changes affect the capability of the North Atlantic Ocean of absorbing atmospheric CO2 and of fixing it inside sinking particulate organic matter. Low-frequency NAO phases determine a delayed response of ocean circulation, temperature and salinity, which in turn affects stratification and marine biogeochemistry. In 20th and 21st century simulations natural wind fluctuations in the North Pacific, related to the two dominant modes of atmospheric variability, affect the spatial structure and the magnitude of the phytoplankton spring bloom through changes in upper-ocean temperature and mixing. The impacts of human-induced emissions in the 21st century are generally larger than natural climate fluctuations, with the phytoplankton spring bloom starting one month earlier than in the 20th century and with ~50% lower magnitude. This PhD thesis advances the knowledge of bio-physical interactions within the global climate, highlighting the intrinsic coupling between physical climate and biosphere, and providing a framework on which future studies of Earth System change can be built on.

description: The issue concerning the relationship between civil liability and social insurance against accidents at work and occupational diseases has been debated for over a century as an outstanding jurisprudence focus. A heated debated, indeed, due to an underlying equivocation never solved, born in that constituent period of social and labour law represented by the liberal policies at the end of 19th century, looking for remedies against the dramatic burden of injuries at work during industrial revolutions without theoretical tools to understand the real meaning of the rising welfare provisions. An underlying equivocation able to repeat itself affecting a large part of theoretical debate even under the new constitutional order, withstanding tenaciously over the ride of living law. Moving from the analysis of that period, the A. investigates in depth the current conditions and limits of the INAIL regressive action, also considering the actual theorical structure of the traditional idea of the regressive actions as an original and autonomous right of INAIL. This thesis, starting from the various positions of the past and present debate, overcomes the many inconsistencies of the traditional thesis, recognizing to the INAIL regressive action a specific constitutional value, and according to these assumptions, investigates both the actuality of the distinction between the special action of art. 11 T.U. and the subrogation action of art. 1916 c.c., and the actual relationship between civil liability and social insurance, in the context of new conceptions of personal injury.
Vortex nucleation processes in rotating lattices of Bose-Einstein condensates ruled by the on-site phases

description: We study the nucleation and dynamics of vortices in rotating lattice potentials where weakly linked condensates are formed with each condensate exhibiting an almost axial symmetry. Due to such a symmetry, the on-site phases acquire a linear dependence on the coordinates as a result of the rotation, which allows us to predict the position of vortices along the low density paths that separate the sites. We first show that, for a system of atoms loaded in a four-site square lattice potential, subject to a constant rotation frequency, the analytical expression that we obtain for the positions of vortices of the stationary arrays accurately reproduces the full three-dimensional Gross-Pitaevskii results. We then study the time-dependent vortex nucleation process when a linear ramp of the rotation frequency is applied to a lattice with sixteen sites. We develop a formula for the number of nucleated vortices which turns to have a linear dependence on the rotation frequency with a smaller slope than that of the standard estimate which is valid in absence of the lattice. From time-dependent Gross-Pitaevskii simulations we further find that the on-site populations remain almost constant during the time evolution instead of spreading outwards, as expected from the action of the centrifugal force. Therefore, the time-dependent phase difference between neighboring sites acquires a running behavior typical of a self-trapping regime. We finally show that, in accordance with our predictions, this fast phase-difference evolution provokes a rapid vortex motion inside the lattice. Our analytical expressions may be useful for describing other vortex processes in systems with the same on-site axial symmetry.

description: The cross section and the transverse-longitudinal asymmetry A_{TL} of the three-body-break-up (3BBU) process 3He(e,e'p)pn have been calculated by a non-factorized and parameter-free approach based upon realistic few-body wave functions corresponding to the $AV18$ interaction, treating the rescattering of the struck nucleon within a generalized eikonal approximation. The results of calculations exhibit a good agreement with recent JLab experimental data and show that the Final State Interaction (FSI) of the struck proton in the region of missing momentum 300 < p_m < 600 MeV/c and removal energy E_m > p_m^2/4m_N is dominated by single nucleon rescattering, in agreement with nucleon-nucleon correlation predictions.

Optimal estimators and asymptotic variances for nonequilibrium path-ensemble averages

description: Existing optimal estimators of nonequilibrium path-ensemble averages are shown to fall within the framework of extended bridge sampling. Using this framework, we derive a general minimal-variance estimator that can combine nonequilibrium trajectory data sampled from multiple path-ensembles to estimate arbitrary functions of nonequilibrium expectations. The framework is also applied to obtaining asymptotic variance estimates, which are a useful measure of statistical uncertainty. In particular, we develop asymptotic variance estimates pertaining to Jarzynski's equality for free energies and the Hummer-Szabo expressions for the potential of mean force, calculated from uni- or bidirectional path samples. Lastly, they are demonstrated on a model single-molecule pulling experiment. In these simulations, the asymptotic variance expression is found to accurately characterize the confidence intervals around estimators when the bias is small. Hence, it does not work well for unidirectional estimates with large bias, but for this model it largely reflects the true error in a bidirectional estimator derived by Minh and Adib.

DATA AND MODEL-BASED RESOURCES TO SUPPORT ITALIAN RICE BREEDING
Creators: name: MONGIANO, GABRIELE
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: The central challenge that humanity is facing is the need to meet the nutritional needs of a growing population. After the tremendous progress achieved during the green revolution, the yields of the primary cereal crops are now stagnating and the undergoing climatic changes represent a further threat. Among the technologies available to allow a further increase in yield, genetic improvement is the most promising. Plant breeding, though, is an expensive, time consuming and labour- intensive activity which relies on a thorough knowledge of the available germplasm for its efficient exploitation requiring the integration of the phenotypic expression with molecular data. The analysis of the interactions between genetic makeup, pedo-climatic conditions and management practices is thus essential to guide breeding programs aimed at improving the agronomic traits of the main herbaceous crops. Crop simulation modelling can be used to support such activities, via a cost- and time-efficient analysis of the performances of a wide range of phenotypes in different weather, soil and management conditions. The requirement is the minimum deviation between the phenotypic expression and its model representation, which should consider the known physiological limits and compensatory effects among traits. The lack of an extensive characterisation of available germplasm often impedes the availability of exhaustive data to support breeding programs via crop modelling. This applies to Italian rice agriculture, being characterized by a long history of cultivation with a vast varietal landscape. Crop model-based studies and services have already been developed in the area to support rice growers and local stakeholders, thus outlining a proficient case study for their implementation in breeding programs. This doctoral project aimed at analysing the morpho-physiological characteristics of the Italian rice germplasm mostly contributing to the yield increase in the 20th century, highlighting the evolutionary trends, and the associations with published molecular data. The released information enlarges previous findings and can be used to guide genetic improvement programs aimed at further improve current rice varieties. The field experimental activity produced ready-to-use quantitative data to further refine crop modelling capabilities in the area. Their integration in a crop model study allowed correlating yield component traits and model parameters, fostering the design of synthetic cultivars to facilitate and prioritize new breeding efforts.

Inductive and Coinductive Predicate Liftings for Effectful Programs

description: We formulate a framework for describing behaviour of effectful higher-order recursive programs. Examples of effects are implemented using effect operations, and include: execution cost, nondeterminism, global store and interaction with a user. The denotational semantics of a program is given by a coinductive tree in a monad, which combines potential return values of the program in terms of effect operations. Using a simple test logic, we construct two sorts of predicate liftings, which lift predicates on a result type to predicates on computations that produce results of that type, each capturing a facet of program behaviour. Firstly, we study inductive predicate liftings which can be used to describe effectful notions of total correctness. Secondly, we study coinductive predicate liftings, which describe effectful notions of partial correctness. The two constructions are dual in the sense that one can be used to disprove the other. The predicate liftings are used as a basis for an endogenous logic of behavioural properties for higher-order programs. The program logic has a derivable notion of negation, arising from the duality of the two sorts of predicate liftings, and it generates a program equivalence which subsumes a notion of bisimilarity. Appropriate definitions of inductive and coinductive predicate liftings are given for a multitude of effect examples. The whole development has been fully formalized in the Agda proof assistant.

Creators: name: VASTA, VALENTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: This PhD thesis focuses on the power to appeal of the public prosecutor against the acquittal. Within an historical perspective, the Author starts with an analysis of the issues related to the overturning of the acquittal given by the first-instance judge, rendered without a direct assessment of the oral evidence. This analysis has been also carried out through the decisions rendered by the European Court of Human Right and the Italian Supreme Court, trying to underline the progressive compliance of the Italian jurisprudence to the European one. In this scenario, the main principle ruled by the Italian Supreme Court requires the Court of Appeal the renewal of the trial evidentiary hearing, when the evidence provided for the acquittal by the first-instance judge have been re-evaluated to prove the guilty. After the reconstruction of the legal and case-law framework, this thesis offers some insights on the relationship between the overturning mechanism and the rights of defense and on the nature of the Appeal.

description: Dwarf galaxies tend to have redder [3.6 micron] - [4.5 micron] Spitzer broadband colors than spirals. To investigate this effect, for a large sample of dwarf galaxies we combine Spitzer fluxes with data at other wavelengths and compare to population synthesis models. Lower metallicity systems are found to have redder [3.6] - [4.5] colors on average, but with considerable scatter. The observed range in [3.6] - [4.5] color is too large to be accounted for solely by variations in stellar colors due to age or metallicity differences; interstellar effects must contribute as well. For the reddest systems, the 4.5 micron luminosity may not be a good tracer of stellar mass. We identify three factors that redden this color in dwarfs. First, in some systems, strong Br-alpha emission contributes significantly to the 4.5 micron emission. Second, in some cases high optical depths lead to strong reddening of the starlight in the Spitzer bands. Third, in some galaxies, the nebular continuum dominates the 4.5 micron flux, and in extreme cases, the 3.6 micron flux as well. The harder UV radiation fields in lower metallicity systems produce both more gaseous continuum in the infrared and more Br-alpha per star formation rate. The combination of these three factors can account for the 4.5 micron excess in our sample galaxies, thus it is not necessary to invoke a major contribution from hot dust to the 4.5 micron band. However, given the uncertainties, we are not able to completely rule out hot dust emission at 4.5 micron. More spectroscopic observations in the 3 - 5 micron range are needed to disentangle these effects.

The Weaker Voice in Asymmetric Alliances. How voice opportunities affect weaker partners' choice for alliance persistence or termination
Creators: name: LEVA, ANDREA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: Diplomatic history provides several examples of weaker allies that take themselves out of military agreements with major powers in charge of guarantying for their security. Unfortunately, alliance theorists have barely been focusing on this empirical puzzle, assuming widely that weaker sides in asymmetric relationships take on a passive attitude. Still, we can find many cases of unsatisfied minor allies that prefer to terminate military agreements instead of continuing to benefit from the stronger side's protection. To solve this puzzle, I argue that the effectiveness of a minor ally?s voice affects its preference for the persistence or termination of an asymmetric alliance.

description: We consider the effects of Galactic substructure on energetic neutrinos from annihilation of weakly-interacting massive particles (WIMPs) that have been captured by the Sun and Earth. Substructure gives rise to a time-varying capture rate and thus to time variation in the annihilation rate and resulting energetic-neutrino flux. However, there may be a time lag between the capture and annihilation rates. The energetic-neutrino flux may then be determined by the density of dark matter in the Solar System's past trajectory, rather than the local density. The signature of such an effect may be sought in the ratio of the direct- to indirect-detection rates.

description: In this paper, we introduce open parity games, which is a compositional approach to parity games. This is achieved by adding open ends to the usual notion of parity games. We introduce the category of open parity games, which is defined using standard definitions for graph games. We also define a graphical language for open parity games as a prop, which have recently been used in many applications as graphical languages. We introduce a suitable semantic category inspired by the work by Grellois and Melliès on the semantics of higher-order model checking. Computing the set of winning positions in open parity games yields a functor to the semantic category. Finally, by interpreting the graphical language in the semantic category, we show that this computation can be carried out compositionally.

description: We propose a theoretical project in which quantum squeezing induces quantum entanglement and Einstein-Podolsky-Rosen steering in a coupled whispering-gallery-mode optomechanical system. Through pumping the $χ^{(2)}$-nonlinear resonator with the phase matching condition, the generated squeezed resonator mode and the mechanical mode of the optomechanical resonator can generate strong quantum entanglement and EPR steering, where the squeezing of the nonlinear resonator plays the vital role. The transitions from zero entanglement to strong entanglement and one-way steering to two-way steering can be realized by adjusting the system parameters appropriately. The photon-photon entanglement and steering between the two resonators can also be obtained by deducing the amplitude of the driving laser. Our project does not need an extraordinarily squeezed field, and it is convenient to manipulate and provides a novel and flexible avenue for diverse applications in quantum technology dependent on both optomechanical and photon-photon entanglement and steering.

description: The simulation of a protein's folding process is often done via stochastic local search, which requires a procedure to apply structural changes onto a given conformation. Here, we introduce a constraint-based approach to enumerate lattice protein structures according to k-local moves in arbitrary lattices. Our declarative description is much more flexible for extensions than standard operational formulations. It enables a generic calculation of k-local neighbors in backbone-only and side chain models. We exemplify the procedure using a simple hierarchical folding scheme.

description: Electronic structure and electron correlations of the Hubbard model on the Beta-Mn lattice have been investigated on the basis of the momentum dependent local ansatz wavefunction method. It is found that the electrons on the Beta-Mn lattice are significantly correlated as compared with those on the face centered cubic (fcc) and the body centered cubic (bcc) lattices; the correlation energy gain of the Beta-Mn lattice structure is the largest among the Beta-Mn, the fcc, and the bcc structures, and the charge fluctuations show a significant suppression. In particular, it is found that the mass enhancement factor on the Beta-Mn lattice shows a large peak around the electron number per atom n=1.1 when n is varied at the typical Coulomb interaction energy strength of transition metals. It is pointed that the large mass enhancement may explain anomalous electronic specific heat coefficient in Beta-Mn.

description: Accurate systems for extracting Protein-Protein Interactions (PPIs) automatically from biomedical articles can help accelerate biomedical research. Biomedical Informatics researchers are collaborating to provide metaservices and advance the state-of-art in PPI extraction. One problem often neglected by current Natural Language Processing systems is the characteristic complexity of the sentences in biomedical literature. In this paper, we report on the impact that automatic simplification of sentences has on the performance of a state-of-art PPI extraction system, showing a substantial improvement in recall (8%) when the sentence simplification method is applied, without significant impact to precision.

description: Pictures show that streamer or sprite discharge channels emerging from the same electrode sometimes seem to reconnect or merge though their heads carry electric charge of the same polarity; one might therefore suspect that reconnections are an artifact of the two-dimensional projection in the pictures. Here we use stereo-photography to investigate the full three-dimensional structure of such events. We analyze reconnection, possibly an electrostatic effect in which a late thin streamer reconnects to an earlier thick streamer channel, and merging, a suggested photoionization effect in which two simultaneously propagating streamer heads merge into one new streamer. We use four different anode geometries (one tip, two tips, two asymmetric protrusions in a plate, and a wire), placed 40 mm above a flat cathode plate in ambient air. A positive high voltage pulse is applied to the anode, creating a positive corona discharge. This discharge is studied with a fast ICCD camera, in many cases combined with optics to enable stereoscopic imaging. We find that reconnections as defined above occur frequently. Merging on the other hand was only observed at a pressure of 25 mbar and a tip separation of 2 mm, i.e., for a reduced tip distance of p*d=50 micrometer*bar. In this case the full width at half maximum of the streamer channel is more than 10 times as large as the tip separation. At higher pressures or with a wire anode, merging was not observed.

description: The Internet of Vehicles (IoV) is flourishing and offers various applications relating to road safety, traffic and fuel efficiency, and infotainment. Dealing with security and privacy threats and managing the trust (detecting malicious and misbehaving peers) in IoV remains the most significant concern. Artificial Intelligence is one of the most revolutionizing technologies, and the predictive power of its machine learning models can help detect intrusions and misbehaviors. Similarly, empowering the state-of-the-art IoV security framework with blockchain can make it secure and resilient. This article discusses joint AI and blockchain for security, privacy and trust-related risks in IoV. This paper also presents problems, challenges, requirements and solutions using ML and blockchain to address aforementioned issues in IoV.

description: Can a machine or algorithm discover or learn the elliptical orbit of Mars from astronomical sightings alone? Johannes Kepler required two paradigm shifts to discover his First Law regarding the elliptical orbit of Mars. Firstly, a shift from the geocentric to the heliocentric frame of reference. Secondly, the reduction of the orbit of Mars from a three- to a two-dimensional space. We extend AI Feynman, a physics-inspired tool for symbolic regression, to discover the heliocentricity and planarity of Mars' orbit and emulate his discovery of Kepler's first law.

description: At a time when the need for wireless communication in commercial devices is becoming increasingly compelling, the possibilities in medical devices are also growing. The ability to use implants to observe and record mechanisms in the human body not only allows a deeper understanding of the human body, but also to intervene quickly in emergencies. In order to access the information obtained by the implants without additional operations or physical connection to the outside, they are often equipped with Ultra-Wideband (UWB) transceivers. This thesis presents two concepts that significantly reduce the complexity and cost of testing Impulse-Radio (IR)-UWB transceivers for medical applications, firstly in the laboratory and secondly in high-volume production testing. For use in the verification and validation of IR-UWB transceivers in the laboratory, a configurable ultra-wideband pulse modulator is presented that can generate pulses in the sub-nanosecond range. In contrast to many proposed circuits that are built on a chip, the presented circuit is built with commercially available discrete components and is characterised by a high degree of flexibility and power capability. The novel scheme is capable of utilising any applied signal, whether continuous wave signals (CW) or pulsed wave signals (PW), and can generate carrier-based pulses at less than 900 ps. For high-volume production testing, a design-for-test solution is presented to verify the compliance of wireless body area network devices for medical applications with the spectral mask defined in Chapter 9.13 of the IEEE Standard 802.15.6-2012 for IR-UWB and FM-UWB. This solution was implemented for the first time on an Application Specific Integrated Circuit (ASIC) as part of the funded MR-Implant project [1]. It is particularly interesting for high-volume production tests, as it simplifies the verification of, e.g., the power spectral density and the spectral mask for compliance with the standards by measuring fewer and easier-to-measure parameters. The design enables a fast and repeatable IC production test solution for medium to high test volumes that is independent of the type of tester and does not require additional circuitry on an external device interface board. This in turn naturally reduces the complexity of the tests and the associated costs.

description: W-based granular metals have been prepared by electron beam induced deposition from the tungsten-hexacarbonyl W(CO)6 precursor. In situ electrical conductivity measurements have been performed to monitor the growth process and to investigate the behavior of the deposit under electron beam post irradiation and by exposure to air. During the first part of the growth process, the electrical conductivity grows non-linearly, independent of the electron beam parameters. This behavior is interpreted as the result of the increase of the W-particles diameter. Once the growth process is terminated, the electrical conductivity decreases with the logarithm of time, sigma ln(t). Temperature-dependent conductivity measurements of the deposits reveal that the electrical transport takes place by means of electron tunneling either between W-metal grains or between grains and trap sites in the matrix. After venting the electron microscope the electrical conductivity of the deposits shows a degradation behavior, which depends on the composition. Electron post-irradiation increases the electrical conductivity of the deposits.

description: A multicomponent random process used as a model for the problem of space-time earthquake prediction; this allows us to develop consistent estimation for conditional probabilities of large earthquakes if the values of the predictor characterizing the seismicity prehistory are known. We introduce tools for assessing prediction efficiency, including a separate determination of efficiency for "time prediction" and "location prediction": a generalized correlation coefficient and the density of information gain. We suggest a technique for testing the predictor to decide whether the hypothesis of no prediction can be rejected.
