description: In the framework in which supersymmetry is used for understanding fermion masses rather than stabilizing the electroweak scale, we elaborate the phenomenological analysis for the neutrino physics. A relatively large $\sin{θ_{13}}$ is the natural result. The model further predicts vanishingly small CP violation in neutrino oscillations. And $θ_{23}$ is not necessarily maximal. While the high scale supersymmetry generically results in a Higgs mass of about 141 GeV, our model reduces this mass via introducing SU(2)$_L$ triplet fields which also contribute to neutrino masses.

description: This paper presents the design, packaging and measured performance of a redundant 8x8 Reconfiguration Switch Matrix (RSM) at 5.5 GHz for use on board the Data Relay Satellite Systems (DRSS). The RSM includes the RF Switch Matrix (RFSM), a Switch Matrix Controller (SMC) and a Telecommand/Telemetry Interface (TTI). Miniaturization of the RFSM has been achieved by using custom designed MMIC switched amplifiers. The ON-state insertion loss and ON to-OFF isolation for all the 64 RSM paths are measured to be 8 dB and 60 dB (minimum) over 5.3 to 5.7 GHz frequency range, respectively. The gain tracking between the 64 pathes is within 1. dBpp. This design allows for modular 8x8 RFSM expansion or redundant contraction.

description: We investigate an application in the automatic tuning of computer codes, an area of research that has come to prominence alongside the recent rise of distributed scientific processing and heterogeneity in high-performance computing environments. Here, the response function is nonlinear and noisy and may not be smooth or stationary. Clearly needed are variable selection, decomposition of influence, and analysis of main and secondary effects for both real-valued and binary inputs and outputs. Our contribution is a novel set of tools for variable selection and sensitivity analysis based on the recently proposed dynamic tree model. We argue that this approach is uniquely well suited to the demands of our motivating example. In illustrations on benchmark data sets, we show that the new techniques are faster and offer richer feature sets than do similar approaches in the static tree and computer experiment literature. We apply the methods in code-tuning optimization, examination of a cold-cache effect, and detection of transformation errors.

description: In this paper three MMIC designs-a front-end, a VCO, and a high-pass filter-are presented. The circuits include some non-conventional solutions, such as integrated resonators and active filtering, in order to demonstrate the capability to integrate larger RF-systems for 2 GHz wireless telecommunication applications. The measurements of the three circuits showed a good performance, and the agreement with the simulations was excellent due to the process-tolerant design approach.

description: Der Gram-positive Anaerobier Eubacterium acidaminophilum vergärt Aminosäuren in Stickland-Reaktionen, wobei Formiat als Elektronendonor verwendet wird. Zwei zueinander homologe Formiat-Dehydrogenase-Gensätze wurden identifiziert und deren Transkription mittels Northern Hybridisierungen, Primer Extension und RT-PCR untersucht. Beide Gensätze enthalten je ein Gen für die katalytische Untereinheit FdhA und die vermutlich Elektronen-transferierende Untereinheit FdhB. Die Formiat-Dehydrogenase II wurde homogen dargestellt und liegt in vivo assoziiert mit einer Eisen-Hydrogenase vor, deren kodierende Gene ebenfalls identifiziert wurden. Anhand von Sequenzhomologien können für den Komplex aus Formiat-Dehydrogenase und Hydrogenase insgesamt 19 Eisen-Schwefel-Zentren postuliert werden. In der hochaktiven, Sauerstoff-empfindlichen Formiat-Dehydrogenase konnte Wolfram, Selen und Eisen nachgewiesen werden. Das Wolfram wird durch Molybdopterin komplexiert, das Selen in Form von Selenocystein co-translational in die Polypeptidkette inkorporiert. Das Enzym ist in der Lage, neben der Formiat-Oxidation auch die thermodynamisch ungünstige Rückreaktion, die CO2-Reduktion, zu katalysieren. Zur weiteren Charakterisierung des Proteins, das in E. coli nicht als Selenoprotein exprimierbar ist, wurde begonnen, ein Transformationssystem für E. acidaminophilum zu etablieren. In diesem Zusammenhang wurde ein Restriktionsmodifikationssystem charakterisiert, sowie die surface layer untersucht.
description: The Gram-positive anaerobe Eubacterium acidaminophilum ferments amino acids in Stickland reactions using formate as electron donor. Two homologous formate dehydrogenase gene clusters were identified containing one gene each coding for the catalytic subunit FdhA and the presumed electron transferring subunit FdhB. Their transcription was investigated by means of northern hybridizations, primer extension, and RT-PCR. The formate dehydrogenase II was purified to homogeneity. It was shown to be associated with an iron-only hydrogenase whose coding region was identified, too. According to sequence similarities 19 iron-sulfur clustern may be postulated for this complex. The oxygen sensitive, highly active formate dehydrogenase is containing tungsten, selenium, and iron. Tungsten is complexed by molybdopterin, selenium is incorporated as selenocysteine cotranslational into the polypeptide chain. In addition to the formate oxidation, the enzyme was demonstrated to catalyze the thermodynamically unfavourable reduction of CO2. For further characterization of this enzyme that cannot be expressed as selenoprotein in E. coli, the establishment of a transformation system for E. acidaminophilum was started. A restriction modification system as well as the surface layer were characterized.

description: Lehrwerke sollten sich nicht nur auf die Entwicklung sprachlicher Kompetenzen konzentrieren, sondern sich auch um die Förderung interkultureller Kompetenz bemühen. Die Studie untersucht deshalb, inwiefern aktuelle Spanischlehrwerke (Línea verde, Encuentros Edición 3000 und Puente al Español) zur Förderung interkultureller Kompetenz beitragen, und macht Vorschläge, wie Defizite in diesen und künftigen Lehrwerken behoben werden können. Nach einer kritischen Diskussion interkultureller Modelle, Themen und Aufgabenformate wird ein Kriterienkatalog zur Beurteilung des interkulturellen Potenzials von Lehrwerken entwickelt. Anhand dieser Kriterien werden zum einen themengleiche Unidades aus dem jeweils ersten Band qualitativ feinanalysiert, zum anderen erfolgt eine Überblicksanalyse aller Lektionen der Bände 1 und 2. Da die Analyse neben Stärken auch Schwächen der Lehrwerke sichtbar macht, wird eine eigene, thematisch auf die feinanalysierten Lektionen abgestimmte Unidad zur effektiveren Förderung interkultureller Kompetenz entwickelt.
description: Foreign language textbooks should not merely concentrate on the development of linguistic competences, but should also aim at promoting intercultural competence. The study examines what current Spanish language textbooks for German learners (Línea verde, Encuentros Edición 3000 und Puente al Español) contribute to intercultural compe-tence and provides suggestions how deficits can be compensated for in these and in future textbooks. Starting out from a critical discussion of various intercultural models, topics and tasks, a list of criteria is developed for the evaluation of the intercultural potential of textbooks. These criteria are applied in a detailed analysis of thematically related units taken from the first vol-umes; this is complemented by a summarizing analysis of the units of volumes 1 and 2. As the analysis not only shows the advantages, but also pinpoints the weaknesses of the text-books, a new original unit is developed based on the topics examined in the detailed analysis and aimed at promoting intercultural competence more effectively.

Chr. bis zum Ende der Völkerwanderungszeit im 6. Jh. u. Z. analysiert. Dabei wurde bewusst ein naturräumlich einheitliches Areal gewählt, das dank des wenig ausgeprägten eiszeitlichen Reliefs und der fast flächendeckenden Lössauflage seit alters her ein ausgesprochener Gunstraum ist und entsprechend stark genutzt wurde. Die detaillierte Auswertung der Standortfaktoren mittels eines GIS erlaubte es trotzdem, sich den relevanten Aspekten der prähistorischen Siedlungsplatzwahl zumindest anzunähern. Ein weiterer Fokus lag auf aktuellen Fragen der Bodendenkmalpflege, wobei insbesondere Grenzen und Möglichkeiten von Prognosemodellen diskutiert wurden.
description: The publication analyses relevant factors of settlement site choice from the early Neolithic (circa 5500 BC) until the end of the Migration Period (circa 600 AD) in a region of Northwest Saxony. This consistent macrochore, a rolling loess covered plain highly favoured in prehistoric times, was deliberately chosen as the area of interest. The detailed analysis of settlement patterns by means of a GIS made it possible to discern some relevant factors in prehistoric choice of settlement and other sites. Furthermore, actual questions in archaeological heritage management and the possibilities of implementing archaeological prediction models were discussed.

On the bias point selection for improved performance in low intermodulation distortion amplifiers

Subjects: ING-INF/01 Elettronica

description: Conventional design techniques for low in-band intermodulation distortion GaAs MESFET amplifiers, generally indicate a bias-point equal or close to Idss/2 [1,2]. This quiescent point choice results from the will to maximise output current swing without severe distortion, which by no means necessarily implies a minimisation of small-signal intermodulation distortion. The aim of this paper is to review this two types of distortion, and to give precise rules for bias point selection in the design of low IMD amplifiers.

An ethical inquiry : toward education in an infinite condition
Creators: name: Giles, Graham
Publisher: name: University of British Columbia
Year: 2014

description: This study is a philosophical inquiry into the ethical conditions of modernity as these bear upon, and are expressed in, the educational project. In modernity, the ethical is assumed as both a juridical proceduralism (of codes of ethics for teachers, or of a broader legal context) and a moral result (of presupposed good and evil, vested in categories like humanity, liberalism, or difference). When ethics are assumed as completed in the form of codes or ideals, that is, as present and already acted upon, there remains little of an ethics of justice in the ancient sense of the pursuit of the right way to live. Supplanted by imperatives of management and morality, the ethical conditions of living are no longer vital to education. The problem is ontological. The revitalization of the ethical in education requires inquiry into the logics of being. These logics are widely implicated and thus the resources for this inquiry are necessarily historiographical, critical, and speculative. These are deployed in this study in three thematic movements: First to the question of education’s ‘emplacement’ within the modern ethos, or ‘of what’ is educational thought a consequence in the modern ethical settlement; second, how may this be seen to be expressed as ethical thought in contemporary educational discourse; and third, and on the basis of the previous two, to the question of how it may be possible to re-think education ethically. The modern ethical topography is articulated as an oscillation among the ontological forms of conceptual realism (the constructivist procedure of the adequacy of thought to being) and those of ethical idealism (the transcendental production of what cannot be thought). Expressed as ethics of phronesis (practical wisdom) and alterity in educational thought, these are contested on the basis of generic ontology, or that of immanent infinite multiplicity, toward a subjective ethics in education—one that refuses the idealist corruption of the ‘object’ where ethics are concerned. To do so, I propose to educational thought a concept of truth elaborated at the intersection of mathematical formalization (à la Badiou) and comic realism (à la Zupančič).
Cross-talk and interference enhance information capacity of a signaling pathway

description: A recurring motif in gene regulatory networks is transcription factors (TFs) that regulate each other, and then bind to overlapping sites on DNA, where they interact and synergistically control transcription of a target gene. Here, we suggest that this motif maximizes information flow in a noisy network. Gene expression is an inherently noisy process due to thermal fluctuations and the small number of molecules involved. A consequence of multiple TFs interacting at overlapping binding-sites is that their binding noise becomes correlated. Using concepts from information theory, we show that in general a signaling pathway transmits more information if 1) noise of one input is correlated with that of the other, 2) input signals are not chosen independently. In the case of TFs, the latter criterion hints at up-stream cross-regulation. We demonstrate these ideas for competing TFs and feed-forward gene regulatory modules, and discuss generalizations to other signaling pathways. Our results challenge the conventional approach of treating biological noise as uncorrelated fluctuations, and present a systematic method for understanding TF cross-regulation networks either from direct measurements of binding noise, or bioinformatic analysis of overlapping binding-sites.

description: With the appeals for antibiotic-free production and the attention to natural feed additives in poultry. The effects of fresh lemon (FM) supplementation on older laying hens (79–96 weeks) and its comparison with citric acid (CA) and flavomycin (FLA) were evaluated in the present study. Female Jingfen chickens (n = 540) were randomly distributed into 5 dietary treatments: 0 (control), 20 g/kg (2%) and 40 g/kg (4%) FM, 0.7 g/kg CA and 0.005 g/kg FLA. Production performances were recorded daily and egg quality traits were measured biweekly. Serum biochemical indices and antibody titres were detected every 4 weeks from 84 to 96 weeks of age. Compared with the control diet, FM, CA and FLA increased the laying rate (p < .05) and average daily feed intake (ADFI), and reduced the feed to egg ratio (FER), indicating positive effects on production performance. Albumen height and HU were increased by 2% and 4% FM groups compared to the control, while albumen height was decreased in CA and FLA groups. FM improved serum antioxidant enzyme activities (p < .05) and reduced serum HDL, LDL, TG and T-CH compared to other groups, indicating favourable effects on antioxidative status and lipid metabolism. Antibody titres against H5N1, H9N2 and NDV were higher in FM groups than that in other groups during most experimental periods (p < .05). In conclusion, FM supplementation enhanced the production performance and antioxidant capacity of laying hens during the late laying period and was superior to the CA and FLA in improving albumen quality, immune status and lipid metabolism.HIGHLIGHTSFM supplementation in layers’ diets had positive effects on production performance, egg albumen quality and lipid metabolism, and could enhance antioxidant capacity and immune levels.Adding FM had better effects on the albumen quality, immune status and lipid metabolism of laying hens than adding CA and FLA during the late laying period. FM supplementation in layers’ diets had positive effects on production performance, egg albumen quality and lipid metabolism, and could enhance antioxidant capacity and immune levels. Adding FM had better effects on the albumen quality, immune status and lipid metabolism of laying hens than adding CA and FLA during the late laying period.

description: Let F be a surface and suppose that ϕ: F -> F is a pseudo-Anosov homeomorphism fixing a puncture p of F. The mapping torus M = M_ϕis hyperbolic and contains a maximal cusp C about the puncture p. We show that the area (and height) of the cusp torus bounding C is equal to the stable translation distance of ϕacting on the arc complex A(F,p), up to an explicitly bounded multiplicative error. Our proof relies on elementary facts about the hyperbolic geometry of pleated surfaces. In particular, the proof of this theorem does not use any deep results in Teichmueller theory, Kleinian group theory, or the coarse geometry of A(F,p). A similar result holds for quasi-Fuchsian manifolds N = (F x R). In that setting, we find a combinatorial estimate for the area (and height) of the cusp annulus in the convex core of N, up to an explicitly bounded multiplicative and additive error. As an application, we show that covers of punctured surfaces induce quasi-isometric embeddings of arc complexes.

Archaic Pentatonic Melodies in Pindus Mountain –Range in Northern Greece. The hemitonic and anhemitonic pentatonic tunings in Greece and their contribution to the interpretation of early Ancient Greek musical forms

description: The hemitonic pentatonic tuning in Western Greece attested by the author and the anhemitonic tuning previously documented in the area of Epirus but apparently present in all Western Greece, were two main reasons for the investigation and classification of the co-related micro-scales found in the wider area of Pindus. Though many scholars both Greeks and others managed to explain the peculiarities of this musical system found in Western Greece and today’s Southern Albania (Northern Epirus), they failed to do so, as they attributed specific functionalities of the system to simple imitations of instrumental practices. Nonetheless extensive field research in the area of Pindus and in Northern Epirus reveal important correspondences between the function of the melodies of this contemporary system and the “obscure”  information about the evolution of the musical system in Greek (and one might generally say) in Balkan antiquity.
Two dimensions of this musical system are of great importance in relation to the ancient sources. The first is that hemitonic pentatonism (a tuning responsible for the genesis of the enharmonic genus in Antiquity) is still a part of the contemporary musical system in the Greek mainland. The other is that the combination of the two pentatonic tunings reveals a process that can come to a heptachord system existing in its on right. The functionality of the micro-scales also reveal in a unique way the importance of the witness of Nichomachus regarding the evolutionary process for the genesis of the octachord out of the heptachord system and the witness of Aristotle regarding the co-existence of two heptachord systems one “diatonic” and the other anhemitonic.
Apart from the above conclusions, evaluating this data makes clear that it was possible for a diatonic heptachord system to appear by a combination of the two systems: the hemitonic and anhemitonic pentatonic. This information deviates from the theory of the blown fifths as it is based on vocal music.

description: The theory of multidimensional persistent homology was initially developed in the discrete setting, and involved the study of simplicial complexes filtered through an ordering of the simplices. Later, stability properties of multidimensional persistence have been proved to hold when topological spaces are filtered by continuous functions, i.e. for continuous data. This paper aims to provide a bridge between the continuous setting, where stability
properties hold, and the discrete setting, where actual computations are carried out. More precisely, a stability preserving method is developed to compare rank invariants of vector functions obtained from discrete data.
These advances confirm that multidimensional persistent homology is an appropriate tool for shape comparison in computer vision and computer graphics applications. The results are supported by numerical tests.

description: An effective toxicological assessment of soil-metal bioavailability and plant translocation processes is needed in view of the growing negative impact of trace element pollution on the terrestrial environment and human health. This study was conducted to assess the toxicological processes that regulate the plants’ trace element absorption into their tissues, the suitability for human use, the potential sources of trace elements, and the risk to human health, using an integrated research methodology. Soils and sweet potato plants were collected from agricultural fields near the tannery waste disposal sites of Dhaka City, Bangladesh and inductively coupled plasma mass spectrometers (ICP-MS) were used to analyze the essential and toxic elements. The mean concentrations of total elements in soil followed the descending order of Fe > Zn > Mn > Cr > Ni > Pb > Cu > As > Cd and in plant Fe > Zn > Cu > Cr > Ni > Mn > Pb > As > Cd. In the edible tissues of sweet potato, the concentrations of essential and toxic elements exceeded the maximum permissible levels, indicating not safe for human consumption. The translocation factor (TF) revealed that studied elements are more accumulated in the leaves than tubers. The enrichment factor revealed minimal to very high enrichment of essential and toxic elements in the plant parts while the contamination factor showed low to very high contamination. Considering the health risk of toxic elements from plant samples, As and Pb caused non-cancer and cancer risk on human health. However, the present results suggested that regular monitoring of these essential and toxic elements in soil and plants as well as other food materials around the abandoned tannery waste disposal sites are necessary to prevent excessive build-up of these elements in the food chain.

description: Consideration is given to the influence of an underwater landslide on waves at the surface of a shallow body of fluid. The equations of motion which govern the evolution of the barycenter of the landslide mass include various dissipative effects due to bottom friction, internal energy dissipation, and viscous drag. The surface waves are studied in the Boussinesq scaling, with time-dependent bathymetry. A numerical model for the Boussinesq equations is introduced which is able to handle time-dependent bottom topography, and the equations of motion for the landslide and surface waves are solved simultaneously. The numerical solver for the Boussinesq equations can also be restricted to implement a shallow-water solver, and the shallow-water and Boussinesq configurations are compared. A particular bathymetry is chosen to illustrate the general method, and it is found that the Boussinesq system predicts larger wave run-up than the shallow-water theory in the example treated in this paper. It is also found that the finite fluid domain has a significant impact on the behavior of the wave run-up.

description: La autrice dimostra come il progressivo e costante distanziamento dalle sue precedenti opere, e fasi di ricerca, e relativa documentazione della propria indagine scientifica continuativa, sia non solo totale, ma del tutto intenzionale. Il suo procedere nella direzione di una filologia, intersecantesi alla sua stessa composizione scientifica e letteraria, è caratterizzato da un andamento coerente, seppur anomalo, che prevede una durata massima di dodici mesi, per ogni innovazione stilistica, che trasferisce in lingua italiana, dai suoi originali attuali in lingua inglese, o che realizza ex novo direttamente nella composizione dei suoi attuali capitoli, del tutto distinti e distanti dai precedenti per temi stili e finalità. Se infatti in passato la esigenza di fare conoscere intere tratte delle sue opere ed operazioni didattiche era un motivo di identificazione per vasti numeri di suoi allievi ed allieve, lettori assidui, oggi il loro acquisito grado di piena autonomia, e la stabilizzazione assicurata dall' autrice ai suoi classici del pensiero computazionale, le permettono di autorizzare un efficace consolidamento filologico di ognuno dei suoi attuali capitoli in modalità stilisticamente atipiche. In particolare provvedendo lei stessa con una composizione narratologica esplicativa, affianca l' apparato critico al suo testo in fieri, secondo una prassi di autotraduzione dalla lingua italiana, di partenza alla stessa lingua di arrivo ovvero l' italiano, in modo costante. Tale percorso di ecdotica incorporata nel testo, intende garantire la leggibilità semplificata ed al tempo stesso completa e corretta, per quanto riguarda le piste semantiche delle sue composizioni inedite più recenti ( Tonfoni G. 2011-2012). Si tratta di una scelta ecologica rispettosa dell' eccessivo affaticamento dei lettori di suoi capitoli, che, se non da lei stessa resi comprensibili, permangono sovraffollati di congetture estranee, tese a fare diminuire l' impatto bibliografico autoctono delle sue varianti. Una comprensione efficace, verrebbe infatti scoraggiata dalla eccessiva complessità dei riferimenti autobibliografici, che solo una autrice post connessionista, può effettivamente lei stessa proporre e poi decifrare. La completa differenza, di metodi proposti, stili realizzati, teorie concepite ed illustrate attuali della autrice scientifica, è dovuta anche e soprattutto alla sua estrema sensibilità letteraria, che le permette di capire che le condizioni storiche e sociali attuali sono talmente diverse da quelle precedenti da necessitare approcci teorici completamente distinti a volte perfino contrari, a quelli previamente concepiti, per risultare effiicaci oggi.

description: The effect of multiple scatterings on the propagation of hard partonic jets in a dense nuclear medium is studied in the framework of deep-inelastic scattering (DIS) off a large nucleus. Power counting arguments based on the Glauber improved Soft-Collinear-Effective-Theory are used to identify the class of leading power corrections to the process of a single parton traversing the extended medium without emission. It turns out that the effect of longitudinal drag and diffusion (often referred to as straggling) is as important as transverse scattering, when relying solely on power counting arguments. With the inclusion of momentum exchanges in both transverse and longitudinal directions between the traversing hard parton and the constituents of the medium, we derive a differential equation for the time (or distance) evolution of the hard parton momentum distribution. Keeping up to the second order in a momentum gradient expansion, this equation describes in-medium evolution of hard jets which experience longitudinal drag and diffusion plus the transverse broadening caused by multiple scatterings from the medium.

description: L’inserimento di una qualsiasi struttura preposta alla protezione costiera (o portuale) incide notevolmente sull’idrodinamica e la morfologia della zona circostante. Conoscere gli effetti che un’opera determinerà sul territorio è il primo elemento che consente di definire il tipo stesso di opera da progettare e governa alle fasi di progettazione stessa. Da ciò nasce l’esigenza di studiare l’interazione delle strutture artificiali con le onde marittime, le correnti e il trasporto solido. 
Tuttavia, l’analisi dell’interazione tra le onde e le strutture costiere non è uno stru-mento fondamentale soltanto per la progettazione delle opere, ma anche per la messa in sicurezza delle zone di battigia o portuali protette dalle opere stesse. Valutare l’affidabilità di tali opere di difesa, ai fini della rappresentazione dei meccanismi del processo di inondazione delle zone costiere in occasione di mareggiate, necessita della conoscenza e della stima accurata dei fenomeni principali che nascono dall’interazione delle opere con il moto ondoso: la risalita delle onde sul paramento lato mare, la traci-mazione e trasmissione di acqua a tergo delle strutture, la riflessione delle onde che, dopo essersi frante sull’opera, ritornano verso il largo.

description: The objective of change-point detection is to discover abrupt property changes lying behind time-series data. In this paper, we present a novel statistical change-point detection algorithm based on non-parametric divergence estimation between time-series samples from two retrospective segments. Our method uses the relative Pearson divergence as a divergence measure, and it is accurately and efficiently estimated by a method of direct density-ratio estimation. Through experiments on artificial and real-world datasets including human-activity sensing, speech, and Twitter messages, we demonstrate the usefulness of the proposed method.

description: To investigate whether the prothrombotic state (PTS), calcium deficiency and iron deficiency anemia (IDA) in early pregnancy is associated with the risk of gestational diabetes mellitus (GDM). We conducted a retrospective cohort study, including consecutive pregnant women tested for PTS, calcium deficiency and IDA before 20 weeks' gestation between September 1, 2017 and March 21, 2021. For routine prenatal care, pregnant women underwent a 75-g oral glucose tolerance test (OGTT) to make a GDM diagnosis during 24–28 weeks of gestation. Testing data and relevant clinical information were obtained from Shenzhen Baoan Women's and Children's Hospital. To estimate GDM risk of exposures (PTS, calcium deficiency and IDA) in early pregnancy, we used logistic regression to obtain odds ratio (OR) adjusted for maternal age, parity, family history of diabetes and pre-pregnancy body mass index. The cohort included 8396 pregnant women with complete data of exposures and GDM outcomes. Baseline characteristics were not comparable between exposure and control groups. PTS (adjusted OR 2.38, 95% CI 1.61–3.52) or calcium deficiency (adjusted OR 1.23, 95% CI 1.02–1.49) in early pregnancy was independently associated with increased GDM risk after adjusting covariates. There was no significant association between IDA status and GDM risk (adjusted OR 0.86, 95% CI 0.63–1.18). PTS and calcium deficiency in early pregnancy may be independent risk factors of GDM. These findings need further validation in well-designed prospective cohorts.

description: Traditional approach of providing network security has been to borrow tools and mechanisms from cryptography. However, the conventional view of security based on cryptography alone is not sufficient for the defending against unique and novel types of misbehavior exhibited by nodes in wireless self-organizing networks such as mobile ad hoc networks and wireless sensor networks. Reputation-based frameworks, where nodes maintain reputation of other nodes and use it to evaluate their trustworthiness, are deployed to provide scalable, diverse and a generalized approach for countering different types of misbehavior resulting form malicious and selfish nodes in these networks. In this chapter, we present a comprehensive discussion on reputation and trust-based systems for wireless self-organizing networks. Different classes of reputation system are described along with their unique characteristics and working principles. A number of currently used reputation systems are critically reviewed and compared with respect to their effectiveness and efficiency of performance. Some open problems in the area of reputation and trust-based system within the domain of wireless self-organizing networks are also discussed.

description: Le reti neurali artificiali (Artificial Neural Networks, ANN) sono algoritmi di analisi dati e di modellazione numerica. Vengono dette “data driven models”, ossia modelli di calcolo basati sul processamento di dati – ottenuti sperimentalmente o prodotti artificialmente – al fine di testare la sensibilità di un certo fenomeno ad alcuni parametri.
Le ANN sono particolarmente utili nelle analisi di fenomeni in cui il numero di parametri in gioco è molto elevato, e le relazioni fisiche tra essi sono fortemente non lineari e molto complesse. Dal punto di vista della tipologia di modellazione, le ANN costituiscono una “black-box”, dunque l’algoritmo di calcolo prescinde completamente dallo studio del fenomeno fisico che sta alla base della relazione di causa-effetto tra dati di input e di output; pertanto, le ANN sono in grado di elaborare i dati sperimentali a disposizione (input) e produrre delle predizioni dei valori desiderati (output), ricostruendo artificialmente gli effetti della complessa relazione di causa-effetto incognita. 
Obbiettivo di tale lavoro è esaminare la struttura caratteristica di una rete neurale e proporre alcuni esempi di ANN impiegati per la modellazione della portata di tracimazione e del coefficiente di trasmissione di strutture costiere, per sottolineare l’adeguatezza di tali strumenti all’impiego in idraulica marittima e presentarli per eventuali successivi utilizzi, quali, ad esempio, la stima del coefficiente di riflessione ondosa, ad oggi non ancora modellato accuratamente.
