description: Cold high pressure densification (CHPD) is presented as a new way to substantially enhance the critical current density of in situ MgB2 wires at 4.2 and 20 K at fields between 5 and 14 T. The results on two binary MgB2 wires and an alloyed wire with 10 wt.% B4C are presented The strongest enhancement was measured at 20K, where cold densification at 1.85 GPa on a binary Fe/MgB2 wire raised both Jcpara and Jcperp by more than 300% at 5T, while Birr was enhanced by 0.7 T. At 4.2K, the enhancement of Jc was smaller, but still reached 53% at 10 T. After applying pressures up to 6.5 GPa, the mass density dm of the unreacted (B+Mg) mixture inside the filaments reached 96% of the theoretical density. After reaction under atmospheric pressure, this corresponds to a highest mass density df in the MgB2 filaments of 73%. After reaction, the electrical resistance of wires submitted to cold densification was found to decrease, reflecting an improved connectivity. A quantitative correlation between filament mass density and the physical properties was established. Monofilamentary rectangular wires with aspect ratios a/b < 1.25 based on low energy ball milled powders exhibited very low anisotropy ratios, Gamma = Jcpara/Jcperp being < 1.4 at 4.2 K and 10T. The present results can be generalized to alloyed MgB2 wires, as demonstrated on a wire with B4C additives. Based on the present data, it follows that cold densification has the potential of further improving the highest Jcpara and Jcperp values reported so far for in situ MgB2 tapes and wires with SiC and C additives. Investigations are under work in our laboratory to determine whether the densification method CHPD can be applied to longer wire or tape lengths.

description: In the frame of EU rural policy, always more oriented towards environmental concerns and green livelihoods, Romania stands out for the predominance of rural areas and high nature value farming. The country has to face the challenge of joining the modernization process of rural farming systems with the valorization of local assets.
Tourism has emerged as one of the main drivers of change and contributors for a sustainable exploitation of local resources. Rural tourism (RT) can foster the enhancement of the territorial capital (TC), the preservation of public goods (PGs) and the promotion of a more environmental oriented livelihood. 
The research focuses on a case study area, two valleys from Maramureş, where environmental approaches as diversification strategies are partially explored. The work investigates the role of tourism initiatives for the promotion of green oriented practices. 
The first part of the work is based on a literature review and interdisciplinary analysis of secondary data to identify the key issues: from rural development policy, to the concept of TC, of PGs and RT. The Romanian development programmes and related strategies are investigated; afterwards the characteristics of the County and the role of RT as diversification and valorisation policies is considered. 
The second part is based on the collection of primary data through interviews to different local stakeholders (farmers owners of rural guesthouses, local administrators, networks and artisans). The main frequencies are analyzed, a cluster analysis is computed to evaluate the similarities within the most representative groups and a comparative analysis is carried out between the two Valleys. 
The frame of the analysis is based on a set of indicators following the dimensions of the TC, to assess the characteristics of the local stakeholders and to outline the perception about the local PGs and on the adopted strategies to manage the territory.
Final considerations are elaborated and few scenarios are outlined, giving relevance to the importance of improving awareness and creating embeddedness among public-private local stakeholders and resources as a tool for a socio-economic and environmental development of the area.

description: The aftermath of the Global Financial and Economic Crisis of 2007/2008 turned out as a veritable “stress test” for European welfare states. Aiming to stabilize citizens’ living conditions and mitigate socio-economic hardship, European governments have engaged in active crisis management. Yet, the protective capacities of European welfare states vary, as does individuals’ exposure to crisis-induced social risks. Hence, the crisis has impacted countries and the members of different social classes unequally. Against this backdrop, this paper asks how Europeans’ perceptions of the personal impact of the crisis are associated with their welfare attitudes, focusing on variations between social classes and across nations. Using cross-sectional Eurobarometer survey data from 2010 for 27 European countries, I find that perceived crisis impact is associated with greater support for welfare state responsibility and redistribution. However, this association is not homogeneous but moderated by an individual’s class position as well as national economic conditions and social spending levels. More specifically, on the individual level, perceived crisis impact is associated with more favourable welfare attitudes not only among its traditional supporters—such as the working class or the unemployed—but also among its traditional opponents, notably the self-employed. Furthermore, where social spending is higher, welfare state support is less strongly related to perceived crisis impact, suggesting that more encompassing welfare states mitigate the subjective impacts of the crisis. However, redistribution appears to be slightly more contested between those affected and those not affected by the crisis under better economic conditions. Given the challenges facing welfare states across Europe, it remains to be seen how stable a basis of popular support can be formed on these grounds.
title: Study of the 3ω Measurement of the In-Plane and the Cross-Plane Thermal Properties on Anisotropic Thin Film Materials
Creators: name: Zhang, Daxi
Publisher: name: Utah State University
Year: 2018

description: Due to the size of the nano-scale and micro-scale materials, traditional method for measuring the thermal properties of the bulk materials cannot be applied. The 3 OmegaMethod was developed by D. G. Cahill in the early 90s. It was used extensively to measure the thermal properties of thin film dielectric materials. Compare with other simulations or experimental methods, the 3 Omega Method has many advantages. Previous research has indicate that the 3 Omega method is capable of measuring the cross-plane thermal conductivity of thin film materials. In extension, an alternative improvement for measurement of the in-plane thermal conductivity and calculating the difference between the in-plane thermal property and the cross-plane thermal property (anisotropy) are developed based on the concept of the 3 Omega Method.

description: The zero-temperature equation of state is analyzed in low-dimensional bosonic systems. In the dilute regime the equation of state is universal in terms of the gas parameter, i.e. it is the same for different potentials with the same value of the s-wave scattering length. Series expansions of the universal equation of state are reported for one- and two- dimensional systems. We propose to use the concept of energy-dependent s-wave scattering length for obtaining estimations of non-universal terms in the energy expansion. We test this approach by making a comparison to exactly solvable one-dimensional problems and find that the generated terms have the correct structure. The applicability to two-dimensional systems is analyzed by comparing with results of Monte Carlo simulations. The prediction for the non-universal behavior is qualitatively correct and the densities, at which the deviations from the universal equation of state become visible, are estimated properly. Finally, the possibility of observing the non-universal terms in experiments with trapped gases is also discussed.

description: Based on thirteen-month fieldwork in the city of Yiwu, an emergent e-commercial hub in Southeast China, this dissertation looks at the making of a neoliberal e-commerce economy and its political, economic, social, and cultural impacts on e-traders in the locality. Despite some state developmental endeavors, this new economy is largely fostered by grassroots market players and facilitated by large e-platform giants, such as the Alibaba Group. The expansion of this new economy has given individual Chinese e-traders new opportunities to generate wealth and cultural capital, achieve upward social mobility and construct an enterprising subjectivity. Yet, the domination of e-platform giants in this economy has also created a precarious condition for the grassroots e-traders, in which they have to adapt to the changing environment and find creative strategies and tactics to ensure their economic security. Through investigations of their self-reliant discourses and business practices in opposition to state intervention in economy and in individual life, their negotiations over independence and justice under the hegemony of e-platform giants, their struggles for social recognition in urban Chinese society, their moral agency in negotiating and contesting ethics in business encounters, and their employment of self-enterprising and self-disciplining measures in dealing with economic and social uncertainties, this dissertation illustrates how the ongoing formation of the digital regime of accumulation generates an anxious yet flourishing life for the e-traders under neoliberalism as well as speaks to the culturally specific process of subjectivization in China.

description: Abstract

The purpose of this descriptive research was to assess satisfaction of pre-term delivery mothers towards the modified oral stimulation intervention in pre-term infants. The participants were the mothers of 42 premature infants admitted to a tertiary hospital in Thailand who were purposively selected according to the inclusion criteria. Data were collected by using mothers' satisfaction questionnaire about using the oral massage to stimulate suckling and swallowing program which was developed by the researchers with IOC=1.00. The data were analyzed with descriptive statistics: frequency and percentages, mean and standard deviation. It was found that mothers were overall satisfied at a high level (x̅ = 4.76, SD = 0.81) and were most satisfied with the services from nurses (x̅ = 4.85, SD = 0.76), the development of premature infants (x̅ = 4.75, SD = 0. 83) and the use of oral massage application to stimulate suckling and swallowing (x̅ = 4.68, SD = 0.85) consecutively. We concluded that mothers are very satisfied with the use of the oral massage application to stimulate suckling and swallowing in all aspects of premature infants. Therefore, nursing care of mothers after giving birth to premature infants should include the application of oral massage to stimulate the suckling and swallowing of premature infants can be used to prepare mothers and infants before being discharged home.

Publisher: name: University of British Columbia

description: The manganese content of soils from the Lower Fraser Valley has been previously investigated. The studies conducted were conflicting in the total amounts of manganese in the soils. Also there was no attempt in the earlier studies to relate manganese to some of the other oxides in the soils. This study was undertaken to elucidate further the chemistry of manganese in the soils of the Lower Fraser Valley and to evaluate extractants and effects of soil pretreatment on the amount of manganese extracted. Iron, aluminum and silicon, which are commonly associated with soil manganese, were also included in the study. The total manganese concentrations obtained were higher than previously reported, even though the soils were derived from the same area. The distribution of total iron within the soil pedon was closely related to that of manganese. Conventional extractants for amorphous inorganic and organic oxides were evaluated with reducing and chelating agents, for their ability to extract manganese, together with aluminum, iron and silicon. The extractants used were sodium pyrophosphate, acid ammonium oxalate, disodiumEDTA, hydroxylamine hydrochloride and hydroquinone. Hydroquinone was only effective in extracting manganese, while sodium pyrophosphate, disodiumEDTA, acid ammonium oxalate and hydroxylamine hydrochloride extracted larger amounts of manganese, iron and aluminum. Only hydroxyl-amine hydrochloride and acid ammonium oxalate extracted silicon from the samples. All extractants, with the exception of sodium pyrophosphate, were consistent with each other in showing similar distributions of the different elements within the soil pedon. Successive extraction analysis indicated that the elements extracted by hydroxylamine hydrochloride were those derived from the organic and inorganic complexed forms. This study also showed that the preceding extractants may alter the soil system, thus questioning the reliability of successive extraction analysis. The effect of soil pretreatments on the extractability of manganese, iron, aluminum and silicon was also investigated. Some differences were observed between in-situ extraction and air-drying treatments. Freezing and storing moist, contributed to significantly high results. There was no consistency for the effect of the pretreatments on the different soils.
title: An Exploratory Case Study of How High-Performance Team Training Develops Sociomathematical Norms and Differing Levels of Math-Talk
Creators: name: Durfee, Melanie V.

description: This exploratory study investigated the influence of High Performance Team (HPT) training on sociomathematical norms and differing levels of the Math-Talk Learning Community framework (Math-Talk) when sixth-grade student teams solved challenging mathematics problems while working in teams. HPT training involved (1) training students on distinct roles in the team problem-solving process, (2) challenging students with complicated mathematical problems, and (3) holding students accountable for contributions to the team. This research project explored the initial stages of the relationship between HPT and student-to-student mathematics conversations though the lens of the Math-Talk Learning Community framework.
The researcher studied four teams (i.e., four cases) with four middle school students in each team/case during a 7-week timeframe. The research study had three phases. The first phase involved gathering baseline data regarding the students’ sociomathematical norms. During the second phase, the students were trained to work in HPT and then solved challenging mathematics problems in teams. During the last phase, the researcher collected data to explore shifts in sociomathematical norms and student autonomy after the students had the opportunity to be trained and work in HPT. The researcher used descriptive statistics to analyze the quantitative data and open and axial coding to analyze the qualitative data.
The analysis included both within- and cross-case analysis. The descriptive statistics used to analyze the changes in sociomathematical norms and Math-Talk levels indicated that the levels of sociomathematical norms increased when teachers gave students opportunities to participate in mathematics discussion. Specifically, students were most adept in the area of explaining and justifying reasoning and least skilled in the area of indicate when solutions are valid.
The role of the teacher was key to maintaining high levels of Math-Talk. The teachers needed to give appropriate support to maintain these levels in three different areas: (1) select problems that were the appropriate level of complexity and provide scaffolding when needed, (2) ensure students understood the context for the mathematics problems, and (3) teach students how to find their own errors or be ready to give feedback regarding whether students’ answers were correct.

description: Aims: The detection of close and faint companions is an essential step in many astrophysical fields, including the search for planetary companions. A new method called "phase closure nulling" has been proposed for the detection of such faint and close companions based on interferometric observations when the system visibility amplitude is close to zero due to the large diameter of the primary star. We aim at demonstrating this method by analyzing observations obtained on the spectroscopic binary HD 59717. Methods: Using the AMBER/VLTI instrument in the K-band with ~1500 spectral resolution, we record the spectrally dispersed closures phases of the SB1 binary HD 59717 with a three-baseline combination adequate for applying phase closure methods. After a careful data reduction, we fit the primary diameter, the binary flux ratio, and the separation using the phase closure data. Results: We detect the 5-mag fainter companion of HD 59717 at a distance of 4 stellar radii from the primary. We determine the diameter of the primary, infer the secondary's spectral type and determine the masses and sizes of the stars in the binary system. This is one of the highest contrasts detected by interferometry between a companion and its parent star. Based on observations collected at the European Southern Observatory, Paranal, Chile, within the commissioning programme 60.A-9054(A).

title: Assessing the Ecological Implications of the Altered Flow and Sediment Regimes of the Rio Grande Along the West Texas-Mexico Border
Creators: name: Blythe, Demitra E.
Publisher: name: Utah State University

description: Large, exotic (those whose headwaters are in distant places) rivers are some of the most unique and diverse ecosystems on earth. Because they often flow through a multitude of biomes and climates, their waters are a vital resource not only for the organisms that inhabit these rivers, but for human societies as well. Thus, large rivers, like the Rio Grande, that flow through arid and agricultural regions are highly regulated and diverted. Regulation and dewatering upset a river’s natural flow regime (e.g., magnitude, duration, timing of large flood events), subsequently impacting the river’s ability to transport its sediment supply, and eventually perturbing a river into either sediment surplus or deficit. The combination of altered flow and sediment regimes influence the availability of habitat essential for the survival and viability of aquatic organisms, such as fish and invertebrates. In addition, increased deposition of sediment creates areas suitable for invasive riparian vegetation to establish, likely affecting habitat complexity and increasing the abundance of leaf litter deposited into the river. The altered flow and sediment regimes, in combination with invasive riparian vegetation, culminate and eventually affect the food resources and aquatic communities present in a river ecosystem. Most often, the links between the physical perturbations to a system with the biological factors are poorly understood. In this study, we use distinct segments of the Rio Grande along the US-Mexico border to compare areas with greater and lower habitat heterogeneity, water quality, and invasive riparian species abundance to better understand what physical factors can influence aquatic species such as fish and invertebrate communities. We identify critical limiting factors for the native fish community present, and link the altered flow and sediment regimes with the aquatic ecological template of the Rio Grande.

description: The feasibility of humanitarian neutrality has long been debated. In the wake of the 'localisation agenda' in 2016, this debate has taken on a new substance. Concerns have been raised about the ability of local actors to remain neutral, therefore questioning their legitimacy. This thesis brings an anthropological perspective to this contention by exploring the contingencies of political agency for various local actors. First, I examine the discursive process that allows international organisations to associate local politics with deviance. I argue that the framing of 'locality' as a space without history enables the interpretation of political actions as spontaneous transgressions. Second, I question the association between politics and deviance by building upon ethnographies of Somali and Syrian medical aid workers, exploring both the causes and purposes of politics in their humanitarian practice. Drawing on Didier Fassin's 'politics of memory' (2008), I argue the political dispositions of both aid worker and recipient are formed by various intersections between subjective experiences of history, and the objective realities of its conditions. Considering this analysis, a specific meaning of politics emerges - it is used as an operational device to establish humanitarian space. Given this conclusion, I argue the moral basis of these political practices is the defence of human life, therefore reconfiguring the bounds of legitimacy to include pragmatic politics of care.

description: Richard Nixon, the president, has been given little historical credit for the environmental accomplishments of his administration. Indeed, in his post-presidency memoirs Nixon himself shows no interest in the environment and when he does speak to the issue, it is disparagingly.
But ironically, my thesis shows that no administration, before or since, has brought such progress to the multiple issues of environmental quality. The thesis explores the political, social, and historical factors that contributed to the "environmental revolution" of the late 60s and early 70s. The quality of the leaders chosen within the administration helps explain the dichotomy between a negative president and the environmental reform accomplished by his government agencies. It was my privilege to serve with or under these men: Walter Hickel, Russell Train, William Ruckelshaus, John Whitaker, and John Ehrlichman. Dedicated civil servants and other bright, young political appointees joined with me on the environmental agenda.
Accretion disk winds in active galactic nuclei: an X-ray view

Subjects: FIS/05 Astronomia e astrofisica

description: This Thesis focuses on the X-ray study of the inner regions of Active Galactic
Nuclei, in particular on the formation of high velocity winds by the accretion
disk itself. Constraining AGN winds physical parameters is of paramount
importance both for understanding the physics of the accretion/ejection flow
onto supermassive black holes, and for quantifying the amount of feedback
between the SMBH and its environment across the cosmic time. The sources selected for the present study are BAL, mini-BAL, and NAL QSOs,
known to host high-velocity winds associated to the AGN nuclear regions. 

Observationally, a three-fold strategy has been adopted:
- substantial samples of distant sources have been
analyzed through spectral, photometric, and statistical
techniques, to gain insights into their mean properties as a population;
- a moderately sized sample of bright sources has been 
studied through detailed X-ray spectral analysis, to give a first
flavor of the general spectral properties of these sources, also from a temporally resolved point of view;
- the best nearby candidate has been thoroughly studied 
using the most sophisticated spectral analysis techniques applied to
a large dataset with a high S/N ratio, to understand the details of the physics of its accretion/ejection flow.

There are three main channels through which this Thesis has been developed: 
- [Archival Studies]: the XMM-Newton public archival data has been extensively used to analyze both a large sample of distant BAL QSOs, and several individual bright sources, either BAL, mini-BAL, or NAL QSOs.
- [New Observational Campaign]: I proposed and was awarded with new X-ray pointings of the mini-BAL QSOs PG 1126-041 and PG 1351+640 during the XMM-Newton AO-7 and AO-8. These produced the biggest X-ray observational campaign ever made on a mini-BAL QSO (PG 1126-041), including the longest exposure so far. Thanks to the exceptional dataset, a whealth of informations have been obtained on both the intrinsic continuum and on the complex reprocessing media that happen to be in the inner regions of this AGN. Furthermore, the temporally resolved X-ray
spectral analysis field has been finally opened for mini-BAL QSOs.
- [Theoretical Studies]: some issues about the connection between theories and observations of AGN accretion disk winds have been investigated, through theoretical arguments and synthetic absorption line profiles studies.
Controllable Andreev retroreflection and specular Andreev reflection in a four-terminal graphene-superconductor hybrid system

description: We report the investigation of electron transport through a four-terminal graphene-superconductor hybrid system. Due to the quantum interference of the reflected holes from two graphene-superconductor interfaces with phase difference $θ$, it is found that the specular Andreev reflection vanishes at $θ=0$ while the Andreev retroreflection disappears at $θ=π$. This means that the retroreflection and specular reflection can be easily controlled and separated in this device. In addition, due to the diffraction effect in the narrow graphene nanoribbon, the reflected hole can exit from both graphene terminals. As the width of nanoribbon increases, the diffraction effect gradually disappears and the reflected hole eventually exits from a particular graphene terminal depending on the type of Andreev reflection.

description: Since the 1970s, the global rise of environmentalism has attracted growing attention from the social sciences. Although most studies acknowledge the lack of a direct link between environmental activism and environmental policy changes, grassroots activists, social movements and NGOs are widely considered to have made a significant contribution to the global spread of environmentalism. Recently, this standard account has been strongly challenged by neoinstitutionalist approaches. In lieu of elevating the role of local activists, they explain the global rise of environmentalism as a top-down process by stressing the importance of the so-called ‘world environmental regime’. In an attempt to bridge this conceptual divide, the present article examines the interaction between local/national activists and the world environmental regime in the case of South Korea. Based on a quantitative and qualitative analysis of statements, network data and surveys, this study describes the social mechanism driving the rise of environmentalism and demonstrates that its accession was equally shaped by the expansion of the world environmental regime, national configurations of power and the cultural creativity of environmental activists.

description: Electron valleys in transition-metal dichalcogenide monolayers drive novel physics and allow designing multifunctional architectures for applications. We propose to manipulate the electron valleys in these systems for spin/valley filter and valve devices through band engineering. Instead of the magnetic proximity effect that has been extensively used in previous studies, in our strategy, the electron valleys are directly coupled to the spin-polarized states of the two-dimensional ferromagnets. We find that this coupling results in a valley-selective gap opening due to the spin-momentum locking in the transition-metal dichalcogenide monolayers. This physics gives rise to a variety of unexpected electronic properties and phenomena including halfmetallicity, electrically switchable valley polarization, spin/valley filter and valve effects in the transition-metal dichalcogenide monolayers. We further demonstrate our idea in MoTe$_2$/CoCl$_2$ and CoCl$_2$/MoTe$_2$/CoCl$_2$ van der Waals heterojunctions based on first-principles calculations. Thus, our study provides a way of engineering the electron valleys in transition-metal dichalcogenide monolayers for new-concept devices.

description: In den Sozialwissenschaften herrscht heute weitgehend Einigkeit darüber, dass die Demokratie ein Produkt der Moderne ist: Sobald eine Gesellschaft sich auf den Modernisierungspfad begibt, besonders in Sachen Ökonomie, gilt der demokratische Übergang über kurz oder lang als unausweichlich. Je mehr die gesellschaftliche Komplexität zunimmt, desto höher sind die Anforderungen an die Steuerungskapazitäten des Staates. Aus diesem Grund werden autoritäre Entwicklungsdiktaturen langfristig durch liberale Demokratien ersetzt. Die Frage, welche kausalen Ursachen und Mechanismen hinter dem Zusammenhang zwischen Modernisierung und Demokratisierung stehen, ist bislang aber nicht hinreichend beantworter worden. Während die meisten Erklärungsangebote an funktionalistische Konzepte ankn:pfen, nähert sich der vorliegende Artikel diesem Thema aus konstitutionstheoretischer Perspektive. Die Argumentation erfolgt dabei in vier Schritten: Im ersten Schritt werden die Beiträge Parsons’ und Luhmanns zur Erklärung von Demokratisierungsprozessen diskutiert. Im zweiten Schritt folgt ein Überblick über neuere nichtfunktionalistische Ansätze in der Theorie sozialer Differenzierung. Daran anknüpfend wird im dritten Schritt der Zusammenhang zwischen Modernisierung und Demokratisierung am Fallbeispiel Südkoreas (1979–1987) untersucht. Die empirische Analyse erstreckt sich dabei auf soziale Ungleichheitsstrukturen in den Teilsystemen, die Träger und Motive prodemokratischer Proteste und das zeitliche Verlaufsmuster der Auseinandersetzungen zwischen der Demokratiebewegung und dem autoritären Regime. Im vierten Schritt wird das Erklärungspotenzial nicht-funktionalistischer Differenzierungstheorien für die Analyse von Demokratisierungsprozessen diskutiert.

description: We show that the Hilbert-Schmidt distance, unlike the trace distance, between quantum states is generally not monotonic for open quantum systems subject to Lindblad semigroup dynamics. Sufficient conditions for contractivity of the Hilbert-Schmidt norm in terms of the dissipation generators are given. Although these conditions are not necessary, simulations suggest that non-contractivity is the typical case, i.e., that systems for which the Hilbert-Schmidt distance between quantum states is monotonically decreasing form only a small set of all possible dissipative systems for N>2, in contrast to the case N=2 where the Hilbert-Schmidt distance is always monotonically decreasing.

description: Lagrangian description of lightlike p-branes is presented in two equivalent forms - a Polyakov-type formulation and a dual to it Nambu-Goto-type formulation. Next, the properties of lightlike brane dynamics in generic gravitational backgrounds of spherically symmetric and axially symmetric type are discussed in some detail: "horizon straddling" and "mass inflation" effects for codimension-one lightlike branes and ground state behavior of codimension-two lightlike "braneworlds".

description: Gastric cancer (GC) presents a poor prognosis, and its complex tumour microenvironment (TME) makes it difficult to treat. Moreover, the regulatory network involved in GC and the relationship between GC features and the TME remain unclear. In this study, we performed scRNA-seq and scATAC-seq of primary samples of different stages and Lauren classifications. Integrative analysis of the scRNA-seq and scATAC-seq data revealed differences in the regulatory networks of tumour cells and other kinds of cells.

description: The $ O(GeV)$ extra $ U(1)$ gauge boson named U-boson, has been proposed to mediate the interaction among leptons and dark matter (DM), in order to account for the observations by PAMELA and ATIC. In such kind of models, the extra U(1) gauge group can be chosen as $U(1)_{L_i-L_j}$ with $L_i$ the $i-$th generation lepton number. This anomaly-free model provides appropriate dark matter relic density and boost factor required by experiments. In this work the observability of such kind of U-boson at BESIII detector is investigated through the processes $ e^ + e^ - \to Uγ$, followed by $U\to e^+e^-$, $U\to μ^+μ^-$ and $U\to ν\overlineν$. In the invisible channel where U-boson decays into neutrinos, BESIII can measure the coupling of the extra $ U(1)$ down to $ O(10^{- 4}) \sim O(10^{- 5})$ because of the low Standard Model backgrounds. In the visible channel where U-boson decays into charged lepton pair, BESIII can only measure the coupling down to $ O(10^{- 3}) \sim O(10^{- 4})$ due to the large irreducible QED backgrounds.

title: Sensitivity of the Opal Instrument for Gravity Wave Detection
Creators: name: Zia, Kenneth I.
Publisher: name: Utah State University

description: Knowing what goes on in the upper atmosphere (∼80-140 km) is very important to the space science community. There are several competing forces that influence the temperature and densities of neutral molecules in that region. OPAL (Optical Profiling of the Atmospheric Limb) is funded by the National Science Foundation (NSF) to measure the temperature there using light from oxygen molecules (∼760 nm). To accomplish this,OPAL is built into a CubeSat (a satellite the size of a loaf of bread) to be launched from the International Space Station (ISS) at an altitude of about 400 km. This vantage point is needed to see the light that is absorbed before it makes it to the ground, so a satellite is the optimal choice. Similar to looking at a tennis ball in your hand and trying to see the details of the yellow fuzz fibers on the outer edges of the ball, OPAL is trying to see the light emitted from oxygen at the outer edge of the atmosphere (also called the limb). In order to see how well OPAL can detect space weather signatures affecting the oxygen emissions a suite of models are made to simulate its output. This suite is made of: simulating the flight path of CubeSat, modeling where the OPAL instrument is looking, and how the oxygen light changes with where the instrument is looking. Because we are currently in a solar minimum, the occurrence of solar storms and geomagnetic storms are considered rare events. This allows for the concentrating on detecting gravity waves in this region and the minimum values of detecting them with this developed model.
Fast Algebraic Attacks and Decomposition of Symmetric Boolean Functions

description: Algebraic and fast algebraic attacks are power tools to analyze stream ciphers. A class of symmetric Boolean functions with maximum algebraic immunity were found vulnerable to fast algebraic attacks at EUROCRYPT'06. Recently, the notion of AAR (algebraic attack resistant) functions was introduced as a unified measure of protection against both classical algebraic and fast algebraic attacks. In this correspondence, we first give a decomposition of symmetric Boolean functions, then we show that almost all symmetric Boolean functions, including these functions with good algebraic immunity, behave badly against fast algebraic attacks, and we also prove that no symmetric Boolean functions are AAR functions. Besides, we improve the relations between algebraic degree and algebraic immunity of symmetric Boolean functions.
