description: Adapting the powerful integrability-based formalism invented previously for the calculation of gluon scattering amplitudes at strong coupling, we develop a method for computing the holographic three point functions for the large spin limit of Gubser-Klebanov- Polyakov (GKP) strings. Although many of the ideas from the gluon scattering problem can be transplanted with minor modifications, the fact that the information of the external states is now encoded in the singularities at the vertex insertion points necessitates several new techniques. Notably, we develop a new generalized Riemann bilinear identity, which allows one to express the area integral in terms of appropriate contour integrals in the presence of such singularities. We also give some general discussions on how semiclassical vertex operators for heavy string states should be constructed systematically from the solutions of the Hamilton-Jacobi equation.

description: Zielsetzung: In dieser retrospektiven Studie wurden die Daten von 1550 an einem Endometriumkarzinom behandelten Frauen analysiert und der Einfluss der adjuvanten Radiotherapie auf das Gesamtüberleben der Frauen untersucht. Die Daten stammen aus dem Krebsregister Magdeburg. Ergebnis: Bei der Betrachtung des Gesamtüberlebens für alle Patientinnen ohne Rücksicht auf die Risikogruppen zeigte sich ein signifikanter Überlebensvorteil für Frauen mit einer alleinigen VBT Behandlung (80%) im Vergleich zu einer Therapie mit EBRT±VBT (62.0%) oder auch die keine Radiotherapie (keine_ RT) (71.2%) erhalten hatten. Die Patientinnen mit einem niedrigen Rezidivrisiko profitierten nicht von einer adjuvanten Radiotherapie. In der univariaten Analyse zeigte sich für die mittlere und hohe Risikogruppe eine signifikante Verbesserung des Gesamtüberlebens durch eine VBT (HR 0.42, CL0.29-0.60, p < 0.0001). Die EBRT±VBT Therapiegruppe zeigte keinen signifikanten Unterschied bezüglich des Gesamtüberlebens. Nach Berücksichtigung der Prognosefaktoren Alter, Tumorgrad, Tumorstadium, Tumortyp, und Allgemeinzustand zeigte sich in der Multivarianzanalyse weiterhin eine signifikante Verbesserung des Gesamtüberlebens durch die VBT (HR 0.50, CI 0.36 - 0.71). Bei einem Vergleich von keine_ RT und VBT nach Paarung der Patientinnen bezüglich der Parameter Alter, Tumortyp, Tumorgrad, Tumorstadium und Allgemeinzustand wurde eine Risikoreduktion von 17.7% durch die VBT nachgewiesen. Die VBT zeigte in einer weiteren Matching-Analyse für die mittlere und hohe Risikogruppe gegenüber der EBRT±VBT keinen Überlebensvorteil. Schlussfolgerung: Die Studie zeigt einen signifikanten Überlebensvorteil der adjuvanten Radiotherapie für die Gruppen mit einem mittleren und hohen Rezidivrisiko. Gleichzeitig konnte keine zusätzliche Verbesserung des Überlebens durch eine EBRT±VBT gegenüber einer alleinigen VBT gezeigt werden. Die VBT sollte bevorzugt als adjuvante Therapieform angewendet werden. Eine Bestätigung dieser Daten durch prospektive Studien ist dringend erforderlich.

description: Es wurde der Transport von phloemmobilen Substanzen aus kompatiblen Wirtspflanzen in den Parasiten Cuscuta reflexa untersucht und auf der Grundlage der Ergebnisse ein Modell für ihren Transfer entwickelt. Mit Cuscuta reflexa parasitierte isolierte Blätter von Pelargonium zonale wurden zur Charakterisierung der source-sink Beziehungen und Untersuchung der Verteilungsverhältnisse von Assimilaten und xenobiotischen Substanzen während der Etablierung und Funktionalität des Phloemkontaktes verwendet. Die Untersuchungen zum Transfer phloemmobilen Fluoreszenzfarbstoffe [5,6 Carboxyfluoreszein (CF) und 8-Hydroxypyren-1,3,6-Trisulfonsäure (HPTS)] sowie des GFP-expremierenden Kartoffel Virus X erfolgten im Wirt-Parasit-System Nicotiana benthamiana-Cuscuta reflexa. Für Experimente zur Translokation des green fluorescent protein (GFP) standen uns Pflanzen von Nicotiana tabacum cv. Sumsai als Wirt zur Verfügung, die GFP in ihren Geleitzellen unter der Kontrolle des AtSUC 2 Promotors expremieren. Die Ergebnisse der Untersuchungen zur Translokation von kleinmolekularen biotischen und abiotischen Substanzen, Fluoreszenzfarbstoffen, von Viren und von GFP sprechen eindeutig dafür, daß es sich bei dem funktionellen Phloemkontakt zwischen Cuscuta reflexa und ihren Wirten um eine symplastische Verbindung handelt.
description: Transport of phloemmobile substances from compatible host plants into the parasite Cusucta reflexa was investigated and based on our results, a model was developed. Leaves from Pelargonium zonale parasitised with Cuscuta reflexa were used to characterise source-sink relations and partitioning of assimilates and xenibiotic substances during the development of phloem contact between host and parasite. For translocation of phloemmobile fluorescent dyes [5,6 carboxyfluorescein and 8-hydroxypyren-1,3,6-trisulforic acid] and potato virus X expressing GFP host-parasit-systems Nicotiana benthamiana-Cuscuta reflexa were used. For translocation of green fluorescent protein (GFP) we used transgenic Nicotiana tabacum cv. Sumsai as a host, expressing GFP under the control of AtSUC 2 promotor from Arabidopsis thaliana. The results of the translocation experiments with biotic and abiotic phloemmobile substances, fluorescent dyes, viruses and GFP indicate, that compatible host plants and Cusucta reflexa develop a symplastic phloem connection.

description: We study the local properties of eigenvalues for the Hermite (Gaussian), Laguerre (Chiral) and Jacobi $β$-ensembles of $N\times N$ random matrices. More specifically, we calculate scaling limits of the expectation value of products of characteristic polynomials as $N\to\infty$. In the bulk of the spectrum of each $β$-ensemble, the same scaling limit is found to be $e^{p_{1}}{}_1F_{1}$ whose exact expansion in terms of Jack polynomials is well known. The scaling limit at the soft edge of the spectrum for the Hermite and Laguerre $β$-ensembles is shown to be a multivariate Airy function, which is defined as a generalized Kontsevich integral. As corollaries, when $β$ is even, scaling limits of the $k$-point correlation functions for the three ensembles are obtained. The asymptotics of the multivariate Airy function for large and small arguments is also given. All the asymptotic results rely on a generalization of Watson's lemma and the steepest descent method for integrals of Selberg type.

description: Zinc oxide is one of the wide band gap semiconductors.
By using the ZnO-layer as an active channel layer,
transparent transistors (ZnO-TFTs) have been
constructed. The ratio Ion/Ioff of ZnO-TFTs fabricated
on Si-wafers is about 106 and the optical transmittance
of ZnO-TFTs fabricated on glass is more than 80%. It
is also performed that the magnetic properties of ZnO
thin films are controlled by V or Co doping under the
non-equilibrium condition. Ferromagnetic properties
of Co-ZnO films are confirmed by not only SQUID but
also MCD and core-level XAS. Relatively weak signal
of ferromagnetics suggests that a part of the film shows
ferromagnetic character due to the inhomogeneous of
the doped exotic cations (V, Co etc.). These results show
that it is possible to fabricate a transparent spin-FET
that can be operated even in the presence of visible light

description: We report here that a new superconducting phase with much higher Tc has been found in K intercalated FeSe compound with excess Fe. We successfully grew crystals by precisely controlling the starting amount of Fe. Besides the superconducting (SC) transition at ~30 K, we observed a sharp drop in resistivity and a kink in susceptibility at 44 K. By combining thermodynamic measurements with electron spin resonance (ESR), we demonstrate that this is a new SC transition. Structural analysis unambiguously reveals two phases coexisting in the crystals, which are responsible respectively for the SC transitions at 30 and 44 K. The structural experiments and first-principles calculations consistently indicate that the 44 K SC phase is close to a 122 structure, but with an unexpectedly large c-axis of 18.10 Å. We further find a novel monotonic dependence of the maximum Tc on the separation of neighbouring FeSe layers.

(1) Simulation code (codesimul.R) is running alone (2) Real data code (code_vraidata_revfin.R). It makes use of three matrices that change depending on the ecotype: - The Capture History (CH_2106_m.csv, CH_2106_d.csv), rows correspond to individuals and columns to years. For regular killer whales this matrix contains 3 possible observations (observed from the coast, observed depredating, non observed) and 2 observations for Type-D killer whales (observed depredating, non observed) - The Marking status (Mk_2106_m.csv, Mk_2106_d.csv), rows correspond to individuals and columns to years. For both ecotype they contain three possible marking status as described in the ESM. - The maturity status (St_2106_m.csv, St_2106_d.csv), rows correspond to individuals and columns to years. For both ecotype they contain four different state (non identify, new-born, juvenile and adult). Two other matrices are the same for bot ecotype - The standardized effort (Effort_stand_boat.csv) contains the yearly effort divided by the maximum number of photographs taken during the study period. - The state matrix (z_init_cro2705.csv) is used to initiate the state matrix from the models.

description: The non-linear W_{\infty}[μ] symmetry algebra underlies the duality between the W_N minimal model CFTs and the hs[μ] higher spin theory on AdS_3. It is shown how the structure of this symmetry algebra at the quantum level, i.e. for finite central charge, can be determined completely. The resulting algebra exhibits an exact equivalence (a`triality') between three (generically) distinct values of the parameter μ. This explains, among other things, the agreement of symmetries between the W_N minimal models and the bulk higher spin theory. We also study the consequences of this triality for some of the simplest W_{\infty}[μ] representations, thereby clarifying the analytic continuation between the`light states' of the minimal models and conical defect solutions in the bulk. These considerations also lead us to propose that one of the two scalar fields in the bulk actually has a non-perturbative origin.

Cloning and functional characterization of genes involved in the biosynthesis and secretion of essential oil constituents of Lavandula
Creators: name: Demissie, Zerihun Abebe
Publisher: name: University of British Columbia
Year: 2014

description: Several members of the genus Lavandula produce valuable essential oils (EOs) that are primarily constituted of regular and irregular monoterpenes, the C₁₀ class of terpenes. We isolated over 22,000 ESTs from leaves, flowers and glandular trichomes of L. angustifolia and L. x intermedia species to facilitate the discovery of genes regulating the biosynthesis and secretion of EOs. In this study, we identified and studied genes involved in regular and irregular monoterpene biosythesis and secretion. One of these genes, the L. x intermedia lavandulyl pyrophosphate synthase (LiLPPS), catalyzes the head–to–middle condensation of two DMAPP units to produce lavandulyl pyrophosphate in vitro. The apparent Km and kcat of LiLPPS were 208 µM and 0.1 s -¹, respectively. LiLPPS is a novel cis prenyl transferase family member and its identification elucidated the biosynthetic origin of irregular monoterpenes in Lavandula EOs. L. angustifolia β-phellandrene synthase (LaβPHLS) and L. x intermedia 1,8-cineole synthase (LiCINS) transformed geranyl pyrophosphate primarily to β-phellandrene and 1,8-cineole, respectively. The apparent Km and kcat of LaβPHLS were 6.6 µM and 1.8 x 10-² s-¹ while those of LiCINS were 5.8 µM and 8.8 x 10-³ s-¹, respectively. LaβPHLS transcripts were highly abundant in young leaves where β-phellandrene is actively produced. LiCINS mRNA levels paralleled the 1,8-cineole content in flowers of three lavender species, and developmental stages of L. x intermedia inflorescence indicating that the production of 1,8 cineole is likely controlled through transcriptional regulation of LiCINS. The genomic CINS of Lavandula species had identical exon-intron architecture and coding sequences, but intron analysis suggests that LiCINS was most likely inherited from L. latifolia. We also identified the L. angustifolia ABCB1 (LaABCB1) that mediates the efflux of vinblastine when expressed in Xenopus laevis oocytes. Treating oocytes with an oxidative uncoupler, ATPase inhibitor, classical ABC blocker and selected Lavandula de novo monoterpenes inhibited efflux mediated by LaABCB1. LaABCB1 transcripts were constitutively expressed in the EO producing tissues of L. angustifolia, L. latifolia and L. intermedia plants. Both the expression pattern and the in vitro activity of LaABCB1 indicate that it plays a role in monoterpene trafficking in the lavender oil glands.

description: PEN2 und PEN3 stellen wichtige Komponenten der Nichtwirtsresistenz von Arabidopsis thaliana gegen den Oomyceten Phytophthora infestans dar. Basierend auf der pen2-Mutante wurde eine EMS-Mutagenese durchgeführt, um weitere Faktoren dieser Interaktion zu identifizieren. Es wurden 14 unabhängige Mutanten selektiert, die einen enhanced response to Phytophthora infestans (erp) Phänotyp aufweisen. Zwei dieser Mutanten, pen2erp2 und pen2erp6, wurden in der vorliegenden Arbeit charakterisiert. Die für den Phänotyp verantwortliche Mutation konnte für pen2erp2 nicht identifiziert werden. Dahingegen offenbarte die Genomsequenzierung von pen2erp6 einen Nukleotidaustausch in dem Gen At1g08720, welches für die putative MAPKKK EDR1 kodiert. Die Mutation in erp6 liegt innerhalb der Kinasedomäne des Proteins und führt zu einem Verlust der Autophosphorylierungsaktivität. Weitere Experimente deuten auf eine bisher unbekannte Beteiligung von EDR1 an der Antwort auf bakterielle PAMPs hin.
description: PEN2 and PEN3 are important components of the nonhost resistance of Arabidopsis thaliana against the oomycete Phytopthora infestans. Based on the pen2 mutant, EMS-mutagenesis was performed to discover new factors involved in the nonhost resistance in this interaction. Analysis of the resulting progeny revealed 14 independent mutants showing an enhanced response to Phytophthora infestans (erp) phenotype. Two of these mutants, pen2erp2 and pen2erp6, were characterized in this work. The mutation responsible for the observed phenotype could not be identified for pen2erp2. However, whole genome sequencing revealed that pen2erp6 carries a mutation in the coding region of At1g08720, which codes for the putative MAPKKK EDR1. The mutation in erp6 is located within the kinase domain of the protein and seems to cause the loss of the autophosphorylation activity of EDR1. Additional experiments suggest an involvement of EDR1 in the response to bacterial PAMPs.

description: This paper reports on the investigation
of the main phenomenon which limits the lifetime of
capacitive RF MEMS : dielectric charging. To
understand this effect, we have developed specific test
set which measures the electrical (at both low and
microwave frequencies) and electromechanical
performances of RF MEMS to investigate their
reliability. Several experiments have thus been
performed such as DC bias stress and cycling under
different actuation waveforms and environment
conditions. These tests have shown that the dielectric
charging creates a drift of the threshold voltages and
we propose an appropriate figure of merit regarding
the lifetime of capacitive RF-MEMS and a key
parameter to determine the type of the failure which
occurs.

description: This paper includes a series of structural results for von Neumann algebras arising from measure preserving actions by product groups on probability spaces. Expanding upon the methods used earlier by the first two authors \cite{CS}, we obtain new examples of strongly solid factors as well as von Neumann algebras with unique or no Cartan subalgebra. For instance we show that every II$_1$ factor associated with a weakly amenable group in the class $\mathcal S$ of Ozawa is strongly solid, \cite{OzSolid}. There is also the following product version of this result: any maximal abelian $\star$-subalgebra of any II$_1$ factor associated with a finite product of weakly amenable groups in the class $\mathcal S$ of Ozawa has an amenable normalizing algebra. Finally, pairing some of these results with cocycle superrigidity results from \cite{IoaCSR}, it follows that compact actions by finite products of lattices in $Sp(n, 1)$, $n \geq2$, are virtually $W^*$-superrigid.

description: Die Untersuchung der flüssigkristallinen Eigenschaften niedermolekularer Blockmoleküle hat sich in den letzten Jahren zu einem interessanten Forschungsgebiet entwickelt. Zu einer wichtigen Klasse derartiger Moleküle zählen kalamitische Bolaamphiphile mit flexiblen lateralen Substituenten. Die Kombination von amphiphiler Selbstorganisation und das Bestreben zur parallelen Orientierung der rigiden Segmente führt dabei zu neuen, außergewöhnlich komplexen Mesophasenstrukturen. Die vorliegende Arbeit umfasst die Synthese neuer lateral substituierter Bolaamphiphile und eine eingehende Charakterisierung ihrer flüssigkristallinen Eigenschaften mittels Polarisationsmikroskopie, DSC und röntgenographischer Methoden. Sowohl die Größe des lateralen Substituenten als auch dessen chemische Natur (Alkyl-, Perfluoralkyl- und Carbosilangruppen) wurde systematisch variiert. Die synthetisierten Verbindungen zeigen eine große Bandbreite neuer komplexer Mesophasen. Von besonderem Interesse sind dabei kolumnare Phasen mit Zylinderstrukturen, korrelierte und nicht korrelierte lamellare Phasen sowie kubische Mesophasen mit core-shell Morphologie.
description: The investigation of the mesomorphic properties of low molecular weight block molecules has become a field of increasing interest in the last few years. Rigid bolaamphiphiles with flexible lateral chains represent an important class of such compounds. The combination of amphiphilic self-organization with the driving force for parallel arrangement provided by rigid segments leads to the formation of novel exciting complex mesophase structures. The subject of this work is the synthesis of novel lateral substituted bolaamphiphilic molecules and the characterization of their liquid crystal properties by means of polarizing microscopy, DSC and X-ray scattering. The size of the lateral substituents as well as their chemical nature (alkyl, perfluoroalkyl and carbosilane units) was changed systematically. The synthesized compounds show a wide variety of new complex mesophases. Of particular interest are: columnar phases with cylinder structures, correlated and non-correlated lamellar phases as well as cubic phases with core-shell morphology.

description: Silicon dioxide and silicon nitride as well as
other insulating materials are used in micro-electromechanical
systems. However, their tendency for
electrostatic charging diminishes the device reliability. The
charging effect becomes significant when these devices are
subjected to ionizing radiation. The irradiation induced
defects and charging depend on the nature of irradiation,
the underlying metal layers and the metal-insulator
interface properties. The sensitivity of RF microelectromechanical systems to ionizing radiation is presented taking into account experimental data and the simulation of charge generation and induced damage.

description: Das Stratum corneum (SC) stellt mit seinen drei Hauptkomponenten, dem Korneozyt, der interzellulären Lipidmatrix und dem „cornified envelope“ ein hochgeordnetes multilamellares System dar. Die Schicht ist durch ihre außergewöhnliche Lipidzusammensetzung charakterisiert und repräsentiert damit die Hauptpenetrationsbarriere der menschlichen Haut. In der vorliegenden Arbeit wurden zwei Studienpräparate hinsichtlich des Substitutionseffektes auf die epidermale Barrierefunktion nach morphologischer Reduktion des SC durch Tape Stripping an gesunden Probanden getestet. Anhand von etablierten Methoden wie Tewametrie sowie Corneometrie stand die Messung der Barrierefunktionalität und Hydratation des Stratum corneum im Vordergrund. Die Ergebnisse zeigten, dass die gewählte Methodik geeignet ist, um einen Substitutionseffekt an der epidermalen Barriere nachzuweisen. Insbesondere die bipolaren Lipide in diesen Präparaten, wie Phosphatidylcholine, weisen zum einen eine bessere Verträglichkeit auch auf sensitiver Haut auf und können zum anderen die physiokochemischen Gegebenheiten der natürlichen Barriere nachahmen.

description: We introduce an exactly solvable fermion chain that describes a $ν=1/3$ fractional quantum Hall (FQH) state beyond the thin-torus limit. The ground state of our model is shown to be unique for each center of mass sector, and it has a matrix product representation that enables us to exactly calculate order parameters, correlation functions, and entanglement spectra. The ground state of our model shows striking similarities with the BCS wave functions and quantum spin-1 chains. Using the variational method with matrix product ansatz, we analytically calculate excitation gaps and vanishing of the compressibility expected in the FQH state. We also show that the above results can be related to a $ν=1/2$ bosonic FQH state.

description: Hochreine Silizium-Einkristalle enthalten verschiedenste Mikrodefekte. Solche eingewachsenen Defekte, z.B. oktaedrische Leerstellencluster (Voids) können zu einer lokal verminderten Spannungsfestigkeit im elektrisch isolierenden Gate-Oxid von MOS-Strukturen führen. Neben eingewachsenen Defekten wirken sich auch metallische Verunreinigungen negativ auf das Durchbruchsverhalten von Gateoxiden aus. Bisher konnten GOI-Defekte nur auf kleinen Flächen von einigen mm2 lokalisiert werden. Die Motivation dieser Arbeit besteht darin, eine Methode zu entwickeln, die es erlaubt, elektrisch aktive GOI-Defekte großflächig, d.h. über ganze Wafer, abzubilden. Zunächst wurde eine Methode entwickelt, mit der sich GOI-Defekte großflächig durchbrechen lassen. Die Lock-in IR-Thermographie wurde zum erstenmal für die Abbildung der durchgebrochenen GOI-Defekte verwendet und so die Defektverteilung über ganze Wafer sichtbar gemacht. Der Einfluss eingewachsener Defekte und metallischer Verunreinigungen wie Kupfer und Nickel auf das Durchbruchsverhalten von Gateoxiden wird untersucht, wobei neben der Durchbruchsspannung und der Defektdichte auch erstmalig die Defektverteilung berücksichtigt wurde. Die strukturelle Ursache einzelner GOI-Defekte wird mit Hilfe von Transmissionselektronenmikroskopie (TEM) abgebildet.

Besides grown-in defects also metallic contamination may result in a drastic reduction of the breakdown voltage. So far, GOI-defects could only be localized on small areas in the order of some mm2. The motivation of this work is to develop a method, which allows to image the GOI-defect distribution across whole wafers (200 mm and bigger) and to determine the local GOI-defect density. First, a special method for the simultaneous breakdown of all GOI-defects across large areas is developed. In the second step Lock-in IR-Thermography was used the first time for the detection of the GOI-defects and the imaging of the GOI-defect distribution across whole wafers. The influence of grown-in defects and of metallic contamination like copper and nickel on the gate oxide properties were investigated. Besides the evaluation of the breakdown voltage and the defect density also the lateral distribution of grown-in defects across a whole wafer could be observed for the first time. In addition to the determination of the GOI-defect density and distribution, the defect origin was investigated using FIB/TEM.

description: The in-plane anisotropy of the electrical resistivity across the coupled orthorhombic and magnetic transitions of the iron pnictides has been extensively studied in the parent and electron-doped compounds. All these studies universally show that the resistivity $ρ_{a}$ across the long orthorhombic axis $a_{O}$ - along which the spins couple antiferromagnetically below the magnetic transition temperature - is smaller than the resistivity $ρ_{b}$ of the short orthorhombic axis $b_{O}$, i. e. $ρ_{a}

description: В статье рассмотрено понятие и исследованы причины возникновения инфляции, проведена классификация инфляционных процессов по различным критериям, выделены факторы, влияющие на инфляцию. Отмечено, что особым фактором является уровень монополизации экономики, так как монополии могут самостоятельно повышать цены на свои продукты и услуги, не считаясь с рыночной ситуацией, что ведет к недопроизводству, дефициту и росту уровня цен в стране. Подчеркивается влияние инфляции не только на потребительский сектор экономики, но и на инвестиционные процессы. В заключение сделан вывод о негативном влиянии инфляции на макроэкономику, что актуализирует проблему поиска современных методов борьбы с инфляцией.
The use of archaeological resources for the benefit of rural communities in El Salvador

description: In many countries around the world, archaeological resources are seen as an opportunity for social, cultural and economic development. El Salvador is a step behind in taking advantage of their rich archaeological heritage as a means of development. In El Salvador, a weak relationship between government and academia regarding rural communities living near archaeological sites hinders the implementation of strategies that could lead to the management and use of archaeological resources for the benefit of those communities. This triadic relationship is referred to as the “Triangle of Inclusion and Cooperation” (TIC). The objective of this work is to strengthen alliances/partnerships between the three entities included in the TIC, to provide a framework for addressing the uses of local resources, including other alternatives of development according local concerns and needs. The TIC required a thorough exploration and review of published and unpublished studies, government and academic files, interviews with Salvadorian cultural experts, and by personal observations in the field. This study is the first English subject thesis to provide a comprehensive history of the institutionalization of archaeology in El Salvador and to identify factors that shaped the current management of archaeological resources. Its historical process is framed in a socio-political context which is also analyzed in order to understand the level of inclusion of rural communities in academic and government issues. Students, scholars, government officials, and general society will find in this document a broad examination of the management and development of archaeology and its potential in this Central American country. The study represents an important improvement in interdisciplinary studies as it advances the understanding of archaeological management and its implications. It also contributes to the debate concerning the ultimate use and purpose of archaeological studies and policy adopted to protect and develop cultural resources in any country.

description: The analysis of fatigue behavior for
polycrystalline gold microbridges is the aim of this paper. A
description of the fatigue phenomenon for these elementary
structures is presented. It is obtained by combining
elementary in situ test benches of varying dimensions and
cyclic actuation; in the same way, the debugging-time is
determined according to the design. Test benches have been
developed allowing performing bending fatigue tests of
polycrystalline gold structural layers, describing the fatigue
phenomenon and obtaining a constant debugging-time,
whatever the excitation frequency and the beams length.

description: In any society, education plays a pivotal role in meeting the needs and demands of its populace. The responsiveness of education to these societal needs forms the basis for curriculum development, which aims to equip individuals with the requisite skills, attitudes, values, and competences necessary for societal advancement. However, defining curriculum proves to be a multifaceted endeavor, as experts offer diverse interpretations of this fundamental concept. Historically, curriculum was predominantly viewed as the mere content of instruction, devoid of considerations for instructional methodologies. Yet, in the contemporary educational landscape, this antiquated notion no longer suffices.

This abstract delves into the evolution of curriculum discourse, highlighting the shift from a narrow focus on instructional content to a comprehensive approach that encompasses diverse aspects of education. In particular, it critiques curriculum designs that prioritize content over pedagogical strategies, likening them to examination syllabuses, such as those employed by examination bodies like WEAC. Through critical analysis, the abstract emphasizes the imperative for modern curricula to transcend mere content dissemination and instead prioritize holistic educational outcomes. It underscores the importance of aligning curriculum development with societal needs and adopting innovative instructional approaches to foster meaningful learning experiences. Furthermore, it underscores the necessity for ongoing dialogue and reflection within the educational community to ensure that curricular practices remain responsive, relevant, and transformative in addressing the evolving needs of society.

description: Composite pulses have found widespread use in both conventional Nuclear Magnetic Resonance experiments and in experimental quantum information processing to reduce the effects of systematic errors. Here we describe several families of time symmetric and antisymmetric fully compensating composite pulses, inspired by the previous Fn, Gn and BB1 families family developed by Wimperis. We describe families of composite 180 degree pulses (NOT gates) which exhibit unprecedented tolerance of pulse strength errors without unreasonable sensitivity to off-resonance errors, and related families with more exotic tailored responses. Next we address the problem of extending these methods to other rotation angles, and discuss numerical results for 90 degree pulses. Finally we demonstrate the performance of some 90 degree and 180 degree pulses in NMR experiments.

description: В статье проведено исследование стимулирующей и антистимулирующей функции налоговой политики, проводимой государством при преследовании различных целей. В случаях, когда государство стремится сдержать деловую активность в стране, оно применяет на практике приемы антистимулирующей политики. И наоборот, если государство преследует цель повысить предпринимательскую активность, используются
методы стимулирующей налоговой политики. Подробно рассмотрены примеры введения различных налогов и льгот в разных странах, в том числе в России. Доказано, что повышенный уровень налогообложения ведет к чистым потерям общества, поскольку производители перекладывают налоги на потребителей, что находит отражение в росте цен на товары и услуги. В качестве заключения сделан вывод о том, что фискальная политика
является сильнейшим рычагом влияния государства на экономику, поэтому необходимо продолжать совершенствование налоговой политики в современной России.

description: The influence of different types of dielectrics
on the switching behaviour and reliability of capacitive
RF MEMS switches fabricated by metal surfacemicromachining
is investigated. Sputtered AlN layers are
compared to PECVD Si3N4 and Ta2O5 layers. It has been
found that switches with sputtered AlN can be operated
without failure in a wide range of driving conditions.
Besides the dielectric charging problem another
degradation has been observed independent of the
dielectric material. The effect only occurs for operation in
ambient air and is probably caused by an electrochemical
reaction.

description: Hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) has recently aroused increasing attention, especially ST11, the predominant CRKP clone in China. Here, we report a case of hv-CRKP-associated infection and reveal the in-host evolution of its mechanism of resistance to tigecycline and polymyxin under clinical therapy. A total of 11 K. pneumoniae carbapenemase (KPC)-producing CRKP strains were consecutively isolated from a male patient who suffered from continuous and multisite infections and successively received antibiotic treatment, including tigecycline and polymyxin. String and antimicrobial susceptibility tests identified seven hypermucoviscous strains and three tigecycline-resistant and four colistin-resistant strains. Galleria mellonella larvae infection model confirmed the hypervirulence. Pulsed-field gel electrophoresis (PFGE) separated three PFGE clusters among all strains, and further Southern blotting detected that blaKPC-2 was located on the same-sized plasmid. Whole-genome sequencing based on Illumina showed that all strains belonged to the hv-CRKP ST11-KL64 clone. Diverse hypervirulence factors and resistance genes were identified. Further sequencing with the Nanopore platform was performed on the CRKP-Urine1 strain, which contained one virulence plasmid (pVi-CRKP-Urine1) and two resistance plasmids (pKPC-CRKP-Urine1 and pqnrS1-CRKP-Urine1). The gene mutations responsible for tigecycline or colistin resistance were then amplified with PCR followed by sequencing, which indicated that mutations of ramR and lon were the potential loci for tigecycline resistance and that the pmrB, phoQ and mgrB genes for colistin resistance. A novel frameshift mutation of lon was identified in the high-level tigecycline-resistant strain (MIC, 128 mg/L). The results indicate that the hypervirulent ST11-KL64 clone is a potential threat to antiinfection treatment and is capable of rapid and diverse evolution of resistance during tigecycline and polymyxin treatment.
