description: BACKGROUND: In persons with type 1 diabetes (T1D), hypoglycemia is the major limiting factor in achieving optimal glycemic control. All persons with T1D are at risk for hypoglycemia (blood glucose level < 70 mg/dl), which is life-threatening and accompanied by serious physical and psychological symptoms, resulting in profound fear of hypoglycemia (FOH) and reduced quality of life. Young adults with T1D are at risk for FOH and have worse glycemic control and self-management behavior than other age groups with T1D. FOH also results in increased glycemic variability (GV). A major gap exists in how to manage FOH. Our overall objective is to reduce FOH and improve diabetes self-management, glycemic control, and GV in young adults with T1D to reduce or delay diabetes complications and improve quality of life. We aim to (1) determine the feasibility and acceptability of an eight-week cognitive behavioral therapy (CBT)-based Fear Reduction Efficacy Evaluation (FREE) intervention in young adults with T1D who experience FOH; and (2) determine the impact of the FREE intervention, compared to an attention control group, on the outcomes FOH, self-management, glycemic control (A1C), and glycemic variability (continuous glucose monitoring recordings). METHODS/DESIGN: A randomized controlled trial in 50 young adults aged 18 to 35 years with T1D will be used. Eligible subjects will be randomized to the intervention program (Fear Reduction Efficacy Evaluation [FREE]) or attention control group. A one-week run-in phase is planned, with baseline measures of FOH, self-management behavior, A1C, and real-time continuous glucose monitoring recordings (RT-CGM) to calculate GV for both groups. The intervention group will participate in eight weekly individual one-hour sessions using CBT and exposure treatment for specific fears. RT-CGM and a daily FOH diary will be used as feedback cues as part of the FREE program. The attention control group will participate in eight weekly individual one-hour diabetes self-management education (DSME) sessions and wear a RT-CGM device (to measure GV only) over 8 weeks. At completion, FOH will be measured, and RT-CGM recordings will be analyzed to determine differences between the FREE and control groups. DISCUSSION: Findings from this proposed pilot study will serve as the foundation for a larger trial to reduce FOH and improve self-management, glycemic control, and GV.

description: We study the scaling of the magnetic susceptibility in the square Ising model based upon the delta-expansion in the high temperature phase. The susceptibility chi is expressed in terms of the mass M and expanded in powers of 1/M. The dilation around M=0 by the delta expansion and the parametric extension of the ratio of derivatives of chi, chi^{(ell+1)}/chi^{(ell)} is used as a test function for the estimation of the critical exponent gamma with no bias from information of the critical temperature. Estimation is done with the help of the principle of minimum sensitivity and detailed analysis revealed that ell=0,1 cases provide us accurate estimation results. Critical exponent of the sub-leading scaling term is also estimated.

description: Currently, solid disposal is a significant challenge in urban cities. In particular, Kigali City generates thousands of tons of solid waste to be transported and discarded in one city's landfill on a daily basis. It has contributed to the rise of social and environmental problems near the Nduba landfill. Previous studies have emphasized types of waste (liquid and solid) but have been unable to demonstrate land use and cover change because of solid waste disposal since its establishment in 2012. The study aimed to evaluate spatiotemporal changes and the social and environmental implications of solid waste disposal in the Nduba sector. Primary data were collected within a defined study area, whereas secondary data relied on remote sensing and geographic information system (GIS) data. Images of land use/cover were used for spatial analysis and changes before and after landfill establishment. The findings of this study indicate that land use/cover has changed considerably in the last decade. For instance, the built-up area increased within the study area from 69.21ha to 187.56ha in 2001 and 2019, respectively. The change detection of land use/cover indicates that the size of the landfill increased by 18.79 ha in 2019. Forest land has reduced from 199.8ha in 2001 to 104.49ha in 2019. Despite public and private efforts to handle solid waste on-site, residents of Nduba claimed that the landfill had substantial social and environmental impacts.

description: In this study financial risk taking propensity is explored with altogether new facet and classify it in two domains. First domain highlights advantageous aspect for wealth and economic prosperity while second can be a menace for wealth and prosperity. Literature is precisely collected to sharpen this peculiarity and to reach on imperative determinants of each domain. Objective is to create differentiation (distinction, discrepancy, peculiarity) between affective (heuristic) and cognitive domain of financial risk taking propensity using empirical approach. Our results predict that in heuristic domain the bias of dispositional affect and propensity to rely on emotions are significantly dominant factors to take risky investment. Whereas, in beneficial risk taking domain (called cognitive), financial literacy, financial self-efficacy, stock market knowledge and thoughtful analytical processing style found to have significant impact. The evidences reported in this study not only support insightful investment decisions but also elaborate risky behavior of renowned financial players.

description: Sheaves are objects of a local nature: a global section is determined by how it looks locally. Hence, a sheaf cannot describe mathematical structures which contain global or nonlocal geometric information. To fill this gap, we introduce the theory of "gleaves", which are presheaves equipped with an additional "gluing operation" of compatible pairs of local sections. This generalizes the conditional product structures of Dawid and Studený, which correspond to gleaves on distributive lattices. Our examples include the gleaf of metric spaces and the gleaf of joint probability distributions. A result of Johnstone shows that a category of gleaves can have a subobject classifier despite not being cartesian closed. Gleaves over the simplex category $Δ$, which we call compositories, can be interpreted as a new kind of higher category in which the composition of an $m$-morphism and an $n$-morphism along a common $k$-morphism face results in an $(m+n-k)$-morphism. The distinctive feature of this composition operation is that the original morphisms can be recovered from the composite morphism as initial and final faces. Examples of compositories include nerves of categories and compositories of higher spans.

description: The improved QCD light-cone sum rule (LCSR) provides an effective way to deal with the heavy-to-light transition form factors (TFFs). Firstly, we adopt the improved LCSR approach to deal with the $B\to D$ TFF $f^{+}(q^2)$ up to twist-4 accuracy. Due to the elimination of the most uncertain twist-3 contribution and the large suppression of the twist-4 contribution, the obtained LCSR shall provide us a good platform for testing the $D$-meson leading-twist DA. For the purpose, we suggest a new model for the $D$-meson leading-twist DA ($ϕ_{3D}$), whose longitudinal behavior is dominantly determined by a parameter $B$. Moreover, we find its second Gegenbauer moment $a^D_2\sim B$. Varying $B$ within certain region, one can conveniently mimic the $D$-meson DA behavior suggested in the literature. Inversely, by comparing the estimations with the experimental data on the $D$-meson involved processes, one can get a possible range for the parameter $B$ and a determined behavior for the $D$-meson DA. Secondly, we discuss the $B\to D$ TFF at the maximum recoil region and present a detailed comparison of it with the pQCD estimation and the experimental measurements. Thirdly, by applying the LCSR on $f^{+}(q^2)$, we study the CKM matrix element $\Vcb$ together with its uncertainties by adopting two types of processes, i.e. the $B^0/\bar{B}^0$-type and the $B^{\pm}$-type. It is noted that a smaller $B \precsim 0.20$ shows a better agreement with the experimental value on $\Vcb$. For example, for the case of $B=0.00$, we obtain $|V_{cb}|(B^0/\bar{B}^0-{\rm type})=(41.28 {^{+5.68}_{-4.82}} {^{+1.13}_{-1.16}}) \times 10^{-3}$ and $|V_{cb}|(B^{\pm}-{\rm type})=(40.44 {^{+5.56}_{-4.72}} {^{+0.98}_{-1.00}}) \times 10^{-3}$, whose first (second) uncertainty comes from the squared average of the mentioned theoretical (experimental) uncertainties.

description: In Ginzburg-Landau Theory of superconductivity, the density and location of the superconducting electrons are measured by a complex-valued wave function, the order parameter. In this paper, when the intensity of the applied magnetic field is close to the second critical field, and when the order parameter minimizes the Ginzburg-Landau functional defined over a two dimensional domain, the leading order approximation of its $L^2$-norm in `small' squares is given as the Ginzburg-Landau parameter tends to infinity.

description: We analyze several non-Hermitian Hamiltonians with antiunitary symmetry from the point of view of their point-group symmetry. It enables us to predict the degeneracy of the energy levels and to reduce the dimension of the matrices necessary for the diagonalization of the Hamiltonian in a given basis set. We can also classify the solutions according to the irreducible representations of the point group and thus analyze their properties separately. One of the main results of this paper is that some PT-symmetric Hamiltonians with point-group symmetry $C_{2v}$ exhibit complex eigenvalues for all values of a potential parameter. In such cases the PT phase transition takes place at the trivial Hermitian limit which suggests that the phenomenon is not robust. Point-group symmetry enables us to explain such anomalous behaviour and to choose a suitable antiunitary operator for the PT symmetry.

description: Islamic banking achieved remarkable growth as a result of structural developments in products innovation over recent decades. In the aftermath of Global Financial Crises (2008), the growth has been fuelled with faster growth in Islamic banks financing. However, the research mostly remained focused on concepts like risk sharing, liquidity issues and financial innovation, during the formative years of Islamic banking. Examining the influence of Islamic banking on the economic development under different economic condition, therefore, largely remained an unexplored area. This study aims to look into this aspect of Islamic banking and applies dynamic and sensitivity analysis techniques to determine the effects of Islamic financing on the economic growth during different economic periods. The study finds a positive relationship between Islamic banks financing and the economic development. Speed of adjustment estimator provides trade-off between speed of adjustment and cost of being off target. The study provides useful guidance for economists and policy makers to corroborate Islamic banks financing as one of the important drivers of GDP growth. Furthermore, a greater understanding of this framework could be established by investigating the comparative impact of Islamic and conventional bank financing on economic development.

Dieser Artikel leistet einen Beitrag zur fachspezifischen Vermittlung von Informationskompetenz an Biologen. Hierfür wurden mittels einer Umfrage die aktuellen Angebote der deutschen Hochschulbibliotheken im Fach Biologie und ihre Verankerung im Fachbereich ermittelt. Der Schwerpunkt in der Vermittlung von Informationskompetenz liegt auf den Studienanfängern. Anhaltspunkte zur Identifizierung der für die Zielgruppe der Graduierten wesentlichen Themengebiete und ihrer Recherchestrategien im Bereich Informationskompetenz liefern bereits vorhandene fachübergreifende Umfragen. Bislang waren die Biowissenschaften hierbei allerdings unterrepräsentiert. Deswegen erfolgte im Rahmen dieser Arbeit eine Befragung von Masterstudierenden und Promovierenden im Fach Biologie. Die Ergebnisse werden mit den in der Literatur verfügbaren Umfrageergebnissen verglichen, mit den aktuellen Papieren zur Informationskompetenz sowie den fachspezifischen Besonderheiten zusammengeführt und diskutiert. Zudem werden Anhaltspunkte und Ziele für die zukünftige Vermittlung von fachspezifischer Informationskompetenz an Biologen formuliert.

description: Due to the issue of habitat fragmentation, canopy bridges were created to allow arboreal animals to traverse across gaps in the forest. However, canopy bridges are prone to weakening or failure due to load and the elements. To combat this problem, a series of strength tests were conducted to determine a stronger method of constructing the bridges based on the principles of fabric weaving. Weights were hung on various types of ropes, yarns, and wool weaves until they broke to find out their tear strength, as well as to find out their del. Weathering conditions were also simulated by soaking the different materials before testing. The strength of wool and plastic materials were tested and two types of weaves were experimented on: 1 cm spacings and 3 cm spacings in between the warp threads.
 Results show that the less dense the warp threads were, the more the weave was able to stretch, and the stronger the tear strength of the weave was. A single wool yarn strand was very weak, however when weaved together, its strength increased by at least 2400%. However, the weaves were apparently not strong enough since plastic non-biodegradable materials were stronger than biodegradable wool.
 Moving forward, it is recommended that wool be substituted for stronger materials, such as nylon, when building future models of weaved canopy bridges.

description: Farming and agriculture are considered as the pillar for the economic growth of every country. To ensure the food safety and reduce the import of vegetables and fruits to the country, the government usually takes necessary action to increase the production according to the population by adapting latest technologies in the field of agriculture. Oman majorly meets its domestic fruits, vegetables, and cereals demand through imports. Therefore, to red uce import dependency, the country is aiming for self-sufficiency in agricultural products by encouraging its farmers to adopt advanced farming techniques. As per the vision 2040 of Oman, agriculture sector have to get improved with the latest automatic systems to increase the production with less pesticides. The scarcity of clean water resources around the globe has generated a need for their optimum utilization of the available resources for the production of the agriculture. For agriculture, water consumption is very important, proper irrigation of crops usually increases the quality and quantity of crops. This is done by collecting the soil moisture, ambient temperature and humidity from the agriculture farm. Advanced tools and technology can also be used to increase farm yield. Use of latest IoT technologies can help to collect data from the farm and control the devices for the irrigation. IoT based system can be implemented for providing accurate amount of water and fertilizer to the plants and trees. By creating a sensor network, proper water regulation in the agriculture field can be achieved as agriculture is considered as the basis of life .
 In our project we are developing an IoT based smart irrigation system to control the water flow for the plants and trees in the farm This system will work with the solar energy so can be installed in remote places where the electric lines are not available. This system can be monitored and controlled remotely from anywhere in the world using internet.

description: Wie kann auch eine große Anzahl möglicherweise umfangreicher Musiknachlässe zügig sichtbar und benutzbar gemacht werden, wenn gleichzeitig das Personal knapp ist? Die Regeln zur Erschließung von Nachlässen und Autographen (RNA) geben den Standard vor, lassen dabei jedoch durchaus Spielraum für eine an die (personellen) Kapazitäten angepasste, abgestufte Erschließungstiefe. Empirische Studien haben gezeigt, dass sich Benutzende nicht etwa eine möglichst detaillierte Erschließung, sondern vielmehr Übersichtlichkeit, variable Suchmöglichkeiten und rasche Zugänglichkeit wünschen. Entscheidend ist dabei die Zugänglichkeit im Internet. Einschlägige Onlinedatenbank für Nachlässe deutschsprachiger Bibliotheken ist Kalliope, für Musikhandschriften der RISM-OPAC. Musiknachlässe enthalten neben den für Kalliope typischen textuellen Materialien vor allem Notenmaterial, dessen Erschließung besondere Anforderungen stellt. Für eine abgestufte Erschließung von Musiknachlässen sind deshalb beide Nachweisinstrumente zu nutzen. Der Beitrag beschreibt einerseits sehr praxisnah Möglichkeiten, durch Inventarlisten erschlossene Musiknachlässe online sichtbar zu machen, andererseits wendet er Jutta Webers Stufenmodell der Nachlasserschließung auf musikalische Nachlässe an. Dabei werden auch Ideen für die Kooperation mit Schulen und Hochschulen entwickelt. Den Abschluss bildet die Vision vom „Nachlass 2.0“, der von der – spielerisch motivierten – „crowd“ der Amateur- und Profimusiker(innen) (mit-)erschlossen wird.

description: The urban heat island effect has been studied extensively by many researchers around the world with the process of urbanization coming about as one of the major culprits of the increasing urban land surface temperatures. Over the past 20 years, the city of Dallas, Texas, has consistently been one of the fastest growing cities in the United States and has faced rapid urbanization and great amounts of urban sprawl, leading to an increase in built-up surface area. In this study, we utilize Landsat 8 satellite images, Geographic Information System (GIS) technologies, land use/land cover (LULC) data, and a state-of-the-art methodology combining machine learning algorithms (eXtreme Gradient Boosted models, or XGBoost) and a modern game theoretic-based approach (Shapley Additive exPlanation, or SHAP values) to investigate how different land use/land cover classifications impact the land surface temperature and park cooling effects in the city of Dallas. We conclude that green spaces, residential, and commercial/office spaces have the largest impacts on Land Surface Temperatures (LST) as well as the Park’s Cooling Intensity (PCI). Additionally, we have found that the extent and direction of influence of these categories depends heavily on the surrounding area. By using SHAP values we can describe these interactions in greater detail than previous studies. These results will provide an important reference for future urban and park placement planning to minimize the urban heat island effect, especially in sprawling cities.

description: On-shell, analytic S-matrix elements in massless theories are constructed from a finite set of primitive three-point amplitudes, which are fixed by Poincare invariance up to an overall numerical constant. We classify \emph{all} such three-point amplitudes in four-dimensions. Imposing the simplest incarnation of Locality and Unitarity on four-particle amplitudes constructed from these three-particle amplitudes rules out all but an extremely small subset of interactions among higher-spin massless states. Notably, the equivalence principle, and the Weinberg-Witten theorem, are simple corollaries of this principle. Further, no massless states with helicity larger than two may consistently interact with massless gravitons. Chromodynamics, electrodynamics, Yukawa and $ϕ^3$-theories are the only marginal and relevant interactions between massless states. Finally, we show that supersymmetry naturally emerges as a consistency condition on four-particle amplitudes involving spin-3/2 states, which must always interact gravitationally.

description: Zwischen 1993 und 2003 wurde im Rahmen des Braunkohlentagebaus in Zwenkau (Lkr. Leipzig), rund 15 km südlich von Leipzig, auf ca. 30 ha die bis dato größte zusammenhängende Siedlungsfläche der Bandkeramik ausgegraben. Die am westlichen Ufer der Weißen Elster gelegenen Befunde (ehemaliger Ortsteil Eythra) der älteren Linienbandkeramik (LBK) bis jüngeren Stichbandkeramik (SBK) werden seit 2009 in einem DFG- Projekt der Universität Leipzig und des Landesamtes für Archäologie Sachsen aufgearbeitet. Auf der gegenüber liegenden Flussseite wurden bei Ausgrabungen nördlich von Zwenkau unter anderem Siedlungsreste der Ältesten Bandkeramik entdeckt, die die Verfasserin in einer Magisterarbeit bearbeitete. Zwenkau-Nord ist einer von bisher vier Fundplätzen der Ältesten Bandkeramik in Sachsen. Neben Ähnlichkeiten zu anderen ältestbandkeramischen Fundplätzen Mitteldeutschlands, wie Eilsleben und Eitzum, zeigen sich in Zwenkau-Nord auch Unterschiede. Es handelt sich dabei vor allem um Unterschiede in der An- und Abwesenheit bestimmter Merkmale der Keramik. Diese oftmals als chronologisch relevant angesehenen Merkmale werden kritisch betrachtet und letztlich als eher regionale Ausprägungen der materiellen Kultur interpretiert. Zusätzlich werden erste Ergebnisse von Keramikanalysen an Scherben der älteren LBK aus Eythra und Ältesten LBK aus Zwenkau-Nord vorgestellt.
description: Between 1993 and 2003, the largest settlement of the Linear and Stroke-Ornamented Pottery Culture (LBK and SBK) was excavated in an area of 30 ha in the Zwenkau opencast lignite mine (administrative district of Leipzig), about 15 km south of Leipzig. The features dating from the older LBK to the younger SBK were situated on the western bank of the river Weiße Elster (former district of Eythra). In 2009, the Eythra project started as a cooperation between the University of Leipzig and the State Office for Archaeology (Landesamt für Archäologie) in Saxony, funded by the German Research Foundation (DFG). On the eastern bank opposite Eythra, settlement remains from the oldest phase of the LBK were found in the north of Zwenkau. Today, Zwenkau-North is one of four known sites from the earliest phase of LBK in Saxony. Apart from similarities, there are also differences between Zwenkau-North and other sites from this period in Central Germany, such as Eilsleben and Eitzum. They mainly differ in the presence or absence of specific characteristics of the pottery. These characteristics are quite often regarded as chronologically important. In this article, I critically discuss this topic and suggest that the analysed characteristics are mainly affected by the regional situation. I also present some of the first results of a chemical analysis of sherds from the LBK sites in Eythra and Zwenkau-North.

description: We propose a device that allows for the emission of pairs of spin-polarized electrons into the edge-states of a two dimensional topological insulator. Charge and spin emission is achieved using a periodically driven quantum dot weakly coupled to the edge states of the host topological insulator. We present calculations of the emitted time-dependent charge and spin currents of such a dynamical scatterer using the Floquet scattering matrix approach. Experimental signatures of spin-polarized two-particle emission can be found in noise measurements. Here a new form of noise suppression, named $\mathbb{Z}_2$--antibunching, is introduced. Additionally, we propose a set-up in which entanglement of the emitted electrons is generated. This entanglement is based on a post-selection procedure and becomes manifest in a violation of a Clauser-Horne-Shimony-Holt inequality.

These results will provide an important reference for future urban and park placement planning to minimize the urban heat island effect, especially in sprawling cities.

description: The urban heat island effect has been studied extensively by many researchers around the world with the process of urbanization coming about as one of the major culprits of the increasing urban land surface temperatures. Over the past 20 years, the city of Dallas, Texas, has consistently been one of the fastest growing cities in the United States and has faced rapid urbanization and great amounts of urban sprawl, leading to an increase in built-up surface area. In this study, we utilize Landsat 8 satellite images, Geographic Information System (GIS) technologies, land use/land cover (LULC) data, and a state-of-the-art methodology combining machine learning algorithms (eXtreme Gradient Boosted models, or XGBoost) and a modern game theoretic-based approach (Shapley Additive exPlanation, or SHAP values) to investigate how different land use/land cover classifications impact the land surface temperature and park cooling effects in the city of Dallas. We conclude that green spaces, residential, and commercial/office spaces have the largest impacts on Land Surface Temperatures (LST) as well as the Park’s Cooling Intensity (PCI). Additionally, we have found that the extent and direction of influence of these categories depends heavily on the surrounding area. By using SHAP values we can describe these interactions in greater detail than previous studies. These results will provide an important reference for future urban and park placement planning to minimize the urban heat island effect, especially in sprawling cities.

description: The current Internet usage, which was designed over 40 years ago, is facing unparalleled challenges in many aspects in the future. Our future Internet, though there will be more than half million users, the world is about 10% of the way there, and there is a lot of growth to come. As a result worldwide internet traffic and mobile traffic will rise steadily and explosively over the next five years. These issues are usually referred to as ‘green networking’. Despite some proposals for energy- efficient topologies most of the studies are focused on warning the world about this problem. Mainly as the unnecessary energy consumption is being concentrated day by day, the proposed paper make available strategies to save network for future covering through many components such as; wireless networks, wired networks, hybrid networks and the current chemical development happening in the world. Moreover, the proposed project hopes to identify a few strategies that are the key enablers of energy-efficient networking research. Since the proposed project mainly highlights greening the networks, when these strategies come to play nearly 30-35% of energy will be saved through networking for future usage.

description: We study moduli spaces $\mathcal{N}$ of rank 2 stable reflexive sheaves on $\mathbb{P}^3$. Fixing Chern classes $c_1$, $c_2$, and summing over $c_3$, we consider the generating function $\mathsf{Z}^{\mathrm{refl}}(q)$ of Euler characteristics of such moduli spaces. The action of the torus $T$ on $\mathbb{P}^3$ lifts to $\mathcal{N}$ and we classify all sheaves in $\mathcal{N}^T$. This leads to an explicit expression for $\mathsf{Z}^{\mathrm{refl}}(q)$. Since $c_3$ is bounded below and above, $\mathsf{Z}^{\mathrm{refl}}(q)$ is a polynomial. We find a simple formula for its leading term when $c_1=-1$. Next, we study moduli spaces of rank 2 stable torsion free sheaves on $\mathbb{P}^3$ and consider the generating function of Euler characteristics of such moduli spaces. We give an expression for this generating function in terms of $\mathsf{Z}^{\mathrm{refl}}(q)$ and Euler characteristics of Quot schemes of certain $T$-equivariant reflexive sheaves, which are studied elsewhere. Many techniques of this paper apply to any toric 3-fold. In general, $\mathsf{Z}^{\mathrm{refl}}(q)$ depends on the choice of polarization which leads to wall-crossing phenomena. We briefly illustrate this in the case of $\mathbb{P}^2 \times \mathbb{P}^1$.

description: Abstract- The analysis of electric networks containing energy storage elements like a capacitor or an inductor or both a capacitor and an inductor is an essential course for most of the branches of the engineering. The response of such networks is generally obtained by adopting the classical method or by algebraic and analytic methods. This paper presents a convolution method for obtaining the complete response of a series electric network of two passive elements namely an inductor of inductance Ł and a resistor of resistance Ɍ (i.e. a series Ł-Ɍ network), connected to an excitation source of sinusoidal potential. The response obtained by solving the governing differential equation will provide an expression for the electric current which flows in the series Ł-Ɍ network connected to an excitation source of sinusoidal potential. This paper presents a new approach to demonstrate the use of the convolution in obtaining the complete response of a series ŁɌ network through the application of the convolution method. The response obtained by solving the governing differential equation by the application of the convolution method will provide an expression for the electric current. In this paper, the response of a series Ł-Ɍ network is provided as a demonstration of the application of the convolution method.

description: We investigate the robustness of genuine multiparticle entanglement under decoherence. We consider different kinds of entangled three- and four-qubit states as well as random pure states. For amplitude damping noise, we find that the W-type states are most robust, while other states are not more robust than generic states. For phase damping noise the GHZ state is the most robust state, and for depolarizing noise several states are significantly more robust than random states.

description: General Secretary of CPC Central Committee Xi Jinping has stated that education must be emphasized in order to fundamentally eliminate poverty and achieve effective linkage with rural revitalization. According to the Outline of China's Rural Poverty Alleviation and Development (2011-2020), Shaanxi Province has 29 poverty-stricken counties, of which 27 are in southern Shaanxi and 11 are deeply poverty-stricken counties, accounting for nearly 40% of the contiguous poverty-stricken areas in Qinling-Daba mountains. Therefore, the key to poverty alleviation and rural revitalization in Shaanxi lies in southern Shaanxi. Although the current poverty alleviation in southern Shaanxi has achieved remarkable results, there are still high risks and hidden dangers of poverty return. Therefore, taking southern Shaanxi as the field survey point, based on the problem orientation and the main line, this paper deeply explored the common risks and causes of establishing education anti-poverty mechanism to connect with the rural revitalization strategy, and effectively put forward the feasible ideas and countermeasures for establishing long-term mechanism for preventing poverty return through education.

description: In this paper, we propose a multiple-level power allocation strategy for the secondary user (SU) in cognitive radio (CR) networks. Different from the conventional strategies, where SU either stays silent or transmit with a constant/binary power depending on the busy/idle status of the primary user (PU), the proposed strategy allows SU to choose different power levels according to a carefully designed function of the receiving energy. The way of the power level selection is optimized to maximize the achievable rate of SU under the constraints of average transmit power at SU and average interference power at PU. Simulation results demonstrate that the proposed strategy can significantly improve the performance of SU compared to the conventional strategies.

description: Let G be a simple simply-connected group scheme over a regular local scheme U. Let E be a principal G-bundle over A^1_U trivial away from a subscheme finite over U. We show that E is not necessarily trivial and give some criteria of triviality. To this end we define affine Grassmannians for group schemes and study their Bruhat decompositions for semi-simple group schemes. We also give examples of principal G-bundles over A^1_U with split G such that the bundles are not isomorphic to pull-backs from U.

description: An integer additive set-indexer is defined as an injective function $f:V(G)\rightarrow 2^{\mathbb{N}_0}$ such that the induced function $g_f:E(G) \rightarrow 2^{\mathbb{N}_0}$ defined by $g_f (uv) = f(u)+ f(v)$ is also injective. An integer additive set-indexer is said to be $k$-uniform if $|g_f(e)| = k$ for all $e\in E(G)$. An integer additive set-indexer $f$ is said to be a weak integer additive set-indexer if $|g_f(uv)|=max(|f(u)|,|f(v)|)$ for all $u,v\in V(G)$. In this paper, we study the characteristics of certain graphs and graph classes which admit weak integer additive set-indexers.

SYNTHESIS OF NITROGEN-CONTAINING COMPOUNDS VIA NITRENE-TRANSFER CATALYSED BY PORPHYRIN COMPLEXES
Creators: name: ZARDI, PAOLO
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: In this Ph.D. thesis several aspects around the topic of metal porphyrins-catalysed nitrene transfer reactions were investigated. It is worth to remark the importance of this sustainable synthetic methodology, it affords valuable nitrogen-containing compounds using cheap starting materials and, if organic azides are employed as nitrene source, molecular nitrogen is the only by-product of the reaction. The scope of ruthenium porphyrin-catalysed amination reaction was extended to the synthesis of important compounds from a biological and pharmaceutical point of view. New strategies to obtain amino acid derivatives and indoles by C-N bond formation were developed. In particular, the reported synthesis of the latter compounds was the first example of intermolecular reaction between an alkyne species and an organic azide affording the indole motif instead of triazoles; thus, it was demonstrated that a great control on the reaction selectivity can be achieved using metal porphyrin catalysts. The optimisation of these transformations was carried out also by studying the mechanism of the catalytic reaction. The generality of a previously performed mechanistic investigation concerning ruthenium porphyrin catalysed allylic amination was assessed. The point of view of Resonance Raman allowed the study of the catalytic system from a different perspective, whilst kinetic and theoretical studies shed some light into the mechanism of ruthenium-porphyrin catalysed aziridination of olefins and benzylic amination to give ?- and ?-aminoesters. The development of new catalysts to improve the catalytic performances and the process sustainability was also considered. Glycoporphyrin complexes, being potentially active compounds in promoting asymmetric synthesis or reactions in aqueous media, seem suitable for the accomplishment of this target. A preliminary study revealed the good catalytic activity in nitrene and carbene transfer reaction of this biocompatible substances, moreover the basis for a catalyst recovery/reuse system were laid.
