description: By mapping the most advanced elements of the contemporary social interactions, the world scientific collaboration network develops an extremely involved and heterogeneous organization. Selected characteristics of this heterogeneity are studied here and identified by focusing on the scientific collaboration community of H. Eugene Stanley - one of the most prolific world scholars at the present time. Based on the Web of Science records as of March 28, 2016, several variants of networks are constructed. It is found that the Stanley #1 network - this in analogy to the Erdős # - develops a largely consistent hierarchical organization and Stanley himself obeys rules of the same hierarchy. However, this is seen exclusively in the weighted network representation. When such a weighted network is evolving, an existing relevant model indicates that the spread of weight gets stimulation to the multiplicative bursts over the neighbouring nodes, which leads to a balanced growth of interconnections among them. While not exclusive to Stanley, such a behaviour is not a rule, however. Networks of other outstanding scholars studied here more often develop a star-like form and the central hubs constitute the outliers. This study is complemented by a spectral analysis of the normalised Laplacian matrices derived from the weighted variants of the corresponding networks and, among others, it points to the efficiency of such a procedure for identifying the component communities and relations among them in the complex weighted networks.
„Only paradoxes to offer?“ Feministische Demokratie- und Repräsentationstheorie in der „Postdemokratie“
Creators: name: Sauer, Birgit

Year: 2015

description: Der Artikel würdigt erstens die Präzisierungen der feministischen politikwissenschaftlichen Repräsentationskonzepte, konstatiert aber, dass diese im Kontext aktueller Transformationen liberaler Demokratien zu kurz greifen. Eine kritische Erweiterung der politikwissenschaftlichen Diskussionen erfolgt zweitens durch die von dekonstruktivistischen und postkolonialen Theoretikerinnen vorgeschlagene Repräsentationskritik, die drei Dimensionen hervorhebt: die Identitäts-, die Ungleichheits- und die Herrschaftsdimension von Repräsentation. Die Leerstellen der beiden Repräsentationsdebatten werden im Rahmen einer staatstheoretischen feministischen Herangehensweise an Demokratie und Repräsentation aufgehoben, die Repräsentation in sozialen Kräfteverhältnissen verortet.

description: 1. Two experiments were conducted to determine the coefficients of standardised ileal amino acid digestibility for selected high-fibre feedstuffs (Expt.1) and to assess the additivity of coefficients of apparent (cAIAAD) and standardised (cSIAAD) ileal amino acid digestibility for diets containing combinations of sorghum, maize and soybean meal. 2. In Expt. 1, broiler chickens (324) were allocated to 54 metabolism cages (nine diets with six replicates). In Expt. 2, broiler chickens (315) were allocated to 63 cages (seven diets with nine replicates). The diets in Expt. 1 were a nitrogen-free diet plus eight semi-purified diets in which soybean meal (SBM), low-protein SBM (LPSBM), soybean hull, wheat bran, maize bran, rice bran, dried sugarbeet pulp or maize gluten feed were the only sources of protein in the respective diets. In Expt. 2, the seven diets were a nitrogen-free diet, and six semi-purified diets consisting of individual feedstuffs (SBM, maize, or sorghum) or combinations (maize and SBM; sorghum and SBM; or maize, sorghum, and SBM) as the only sources of protein. 3. In both experiments, all the broiler chickens received the same maize-SBM diet formulated to meet nutrient requirements according to the breeder’s recommendations from d 0 to 16. Allocated experiment diets were provided on d 16, and ileal digesta were collected on d 21. 4. In Expt. 1, SBM and LPSBM had greater (P<0.01) cSIAAD for indispensable and dispensable amino acids than the other feedstuffs. Rice bran had greater (P<0.01) cSIAAD values than wheat bran and maize bran, except for Leu, Cys, and Pro. 5. In Expt. 2, predicted cAIAAD values for maize-SBM and maize-sorghum-SBM were generally lower (P<0.01) than actual values. The actual and predicted cSIAAD values for maize-SBM, sorghum-SBM and maize-sorghum-SBM combinations were not significantly different. 6. It was concluded that the standardised amino acid digestibility of sorghum, when combined with other feedstuffs, was additive and that approximately three-quarters of total amino acids in the assayed high-fibre feedstuffs, except for sugarbeet pulp and maize gluten feed, were digestible.
European Governance: Zum Verhältnis von demokratischer und nicht-demokratischer Deliberation im europäischen Mehrebenensystem

description: Nicht wenige sehen in der Europäischen Union mit ihren spezifischen Governance-Formen ein Experimentierfeld für die Entwicklung von demokratischen Strukturen und Prozessen jenseits des Nationalstaats. Die Diskussion wird in den letzten Jahren sehr stark von VertreterInnen einer deliberativen Demokratietheorie geprägt, die – zumeist im Anschluss an konzeptionelle Überlegungen von Jürgen Habermas – die kommunikativen Verständigungspotenziale europäischer Beratungs- und Entscheidungsnetzwerke hervorheben. Der vorliegende Beitrag geht der Frage nach, ob bzw. inwiefern die deliberative Demokratietheorie den (nicht-) demokratischen Charakter der Formen des europäischen Netzwerkregierens zutreffend erfasst und interpretiert. Es wird argumentiert, dass dies nur bedingt der Fall ist: So ist die entfaltete Theorieperspektive einerseits durchaus aufschlussreich, um die Verfahren der politischinstitutionellen Einbindung der deliberativen Politikgestaltung in den Blick zu nehmen; andererseits präsentiert sich die deliberative Demokratietheorie zugleich aber als analytisch defizitär, wenn es darum geht, die politökonomischen und politisch-soziologischen Gründe für die undemokratische Qualität des europäischen Netzwerkregierens zu bestimmen.

description: As RIPK2 (receptor interacting serine/threonine kinase 2) has been shown to to alleviate excessive inflammatory responses, the following study conducted a systematic and in-depth analysis of the mRNA-seq and miRNA-seq data from chicken macrophages with/without over-expression of RIPK2 (oeRIPK2) combined with/without avian pathogenic E. coli (APEC) infection to identify the miRNA-mRNA interaction network and potential signalling pathways involved. A total of 9,201 differentially expressed (DE) mRNAs and 300 DE miRNA were identified in both oeRIPK2+APEC vs. APEC and oeRIPK2 vs. the wild-type (WT). Moreover, 4,269 instances of co-expression between miRNAs and mRNAs were seen involving 1,652 DE mRNAs and 164 DE miRNAs. Functional analysis of the DE mRNAs in the miRNA-mRNA interaction network showed that 223 biological processes and five KEGG pathways were significantly enriched in the two comparisons. In total, 128 pairs of miRNA-mRNA interactions were involved in the identified MAPK signalling pathway and focal adhesion immune related pathways. Significantly, these screened miRNAs (gga-miR-222b-5p and gga-miR-214) and their target genes were highly correlated with APEC infection and RIPK2. These recognised key genes, miRNA and the overall miRNA-mRNA regulatory network, enables better understanding of the molecular mechanism of host response to APEC infection, especially related to RIPK2.

description: We propose a spin-selective coherent electron transfer in a silicon-quantum-dot array. Oscillating magnetic fields and temporally controlled gate voltages are utilised to separate the electron wave function into different quantum dots depending on the spin state. We introduce non-adiabatic and adiabatic protocols which offer fast electron transfer and the robustness against the error in the control-field pulse area, respectively. We also study a shortcut-to-adiabaticity protocol which compromises these two protocols. We show that this scheme can be extended to multi-electron systems straightforwardly and used for non-local manipulations of the electrons.
Traffic prediction with embeddings
Creators: name: Szeiler, Pál
Publisher: name: Zenodo
Year: 2023

description: Forecasting traffic flow is a critical task in transportation and community transport. It involves predicting traffic speed in a road network using historical data. To do this, sensors measure and record the traffic speed on the chosen roads. However, this task is challenging because the sensors’ dependencies cannot be explained only by their relative positions in the Euclidean space. Moreover, traffic speeds highly depend on the day and time. In our experiments, we employed attributed and structural graph embeddings to capture node relationships. One of the advantages of using this form of graph representation is that the embedding can be trained in an
 unsupervised manner, even when node attributes are assigned.
Extremely Correlated Fermi Liquid theory of the $t$-$J$ model in 2 dimensions: Low Energy properties

description: Low energy properties of the metallic state of the 2-dimensional tJ model are presented at various densities and temperatures for second neighbor hopping t', with signs that are negative or positive corresponding to hole or electron doping. The calculation employs a closed set of equations for the Greens functions obtained from the extremely correlated Fermi liquid theory. These equations, when used in $d=\infty$ reproduce most of the known low energies features of the $U=\infty$ Hubbard model. In 2-dimensions we are able to study the variations due to the superexchange J. The resulting Dyson self energy is found to be momentum dependent as expected. The density and temperature dependent quasiparticle weight, decay rate and the peak spectral heights over the Brillouin zone are calculated. We also calculate the resistivity, Hall conductivity and cotangent of the Hall angle in experimentally relevant units. These display significant thermal sensitivity for density n >~ 0.8, signifying an effective Fermi-liquid temperature scale which is two or three orders of magnitude below the bare bandwidth. Flipping the sign of the hopping t', i.e. studying hole versus electron doping, is found to induce a change in curvature of the temperature dependent resistivity from convex to concave at low temperatures. Our results provide a natural route for understanding the observed difference in the temperature dependent resistivity of strongly correlated electron-doped and hole-doped matter.

Wir halten den Großteil seiner Vorschläge für eine Neukonzeptualisierung der Disziplin nicht für zielführend, weil sie im Wesentlichen nur auf eine organisatorische und technische Professionalisierung und Modernisierung der Disziplin, auf eine Anpassung an das angelsächsische Modell, hinauslaufen würden. Stattdessen plädieren wir für ein plurales Wissenschaftsverständnis, in dem sich unterschiedliche Perspektiven und Praxen von Wissenschaft in ihrer Vielfältigkeit gegenseitig akzeptieren.

description: Testosterone has an anabolic effect on skeletal muscle. The testes produce most of the testosterone in vivo, while the adrenal glands contribute smaller amounts. When testis testosterone is deficient the adrenal gland increases steroid hormone synthesis, which is referred to as compensatory testicular adaptation (CTA). To reveal the effects of testis testosterone deficiency on adrenal steroid hormones synthesis and skeletal muscle development, gene expression related to adrenal steroid hormones synthesis and skeletal muscle development were determined by RNA-seq. The results showed that castrating male ducks had significant effects on their body weight but no significant impact on cross-sectional area (CSA) or density of pectoral muscle fibres. In skeletal muscle protein metabolism, expression levels of the catabolic gene atrogin1/MAFbx and the anabolic gene eEF2 were significantly higher, with concomitant increases after castration. The adrenal glands’ alteration of the steroid hormone 11β-hydroxylase (CYP11B1) was significantly lower following castration. Expression pattern analysis showed that the adrenal glands’ glucocorticoid receptor (NR3C1/GR) had a potential regulatory relationship with the skeletal muscle-related genes (Pax7, mTOR, FBXO32, FOXO3, and FOXO4). The data showed that castration affected muscle protein metabolism, adrenal steroid and testosterone synthesis. In addition, it was speculated that, after castration, steroid hormones produced by the adrenal gland could have a compensatory effect, which might mediate the changes in skeletal muscle protein metabolism and development.

description: The spectrum of planar N=6 superconformal Chern-Simons theory, dual to type IIA superstring theory on $AdS_4 \times CP^3$, is accessible at finite coupling using integrability. Starting from the results of [arXiv:1403.1859], we study in depth the basic integrability structure underlying the spectral problem, the Quantum Spectral Curve. The new results presented in this paper open the way to the quantitative study of the spectrum for arbitrary operators at finite coupling. Besides, we show that the Quantum Spectral Curve is embedded into a novel kind of Q-system, which reflects the OSp(4|6) symmetry of the theory and leads to exact Bethe Ansatz equations. The discovery of this algebraic structure, more intricate than the one appearing in the $AdS_5/CFT_4$ case, could be a first step towards the extension of the method to $AdS_3/CFT_2$.

Cultural Exchange and the Corporate Sector: Moving Beyond Statist Public Diplomacy?

description: Traditionelle Ansätze zur Analyse öffentlicher Diplomatie verstehen diese Aktivitäten als die Mittel und Wege für Nationalstaaten, ihre Interessen und Werte gegenüber einer internationalen Zielgruppe zu platzieren, um damit ihr Profil zu stärken, nützliche professionelle und praktische Verbindungen zu etablieren und ein – national wie international – günstiges Umfeld für ihre außenpolitischen Aktivitäten herzustellen. Rezente Studien haben der Rolle des privatwirtschaftlichen Sektors bei der Weiterentwicklung der Ansichten und Denkweisen über nationalstaatliche Diplomatie sowie betreffend die Effektivität einschlägiger Aktivitäten vermehrt Aufmerksamkeit geschenkt, das Hauptaugenmerk verblieb jedoch auf einer Optimierung staatlicher Diplomatie unter Anwendung unternehmerischer Methoden (z.B. „place-“ und „nation-branding“). In diesem Beitrag liegt der Fokus jedoch auf drei Beispielen von Corporate Public Diplomacy, die auf einen stärker eigenständigen Ansatz hinweisen, der außerhalb des staatlichen Paradigmas operiert. Alle drei Beispiele stammen aus dem spezifischen Feld der Austauschprogramme: das Atlantic & Pacific Exchange Programm, das von Rotterdam in den Niederlanden aus betrieben wird, das Institute for Cultural Diplomacy in Berlin und Business for Diplomatic Action in Washington DC. Der Beitrag fragt nach den Motiven hinter diesen Aktivitäten und geht der Frage nach, in welchem Ausmaß diese für eine neue privatwirtschaftlich angeleitete öffentliche Diplomatie stehen, die neben oder sogar getrennt von staatsbasierten Interessen operiert.

Kontroverse Koalitionen im politischen Laboratorium Camp – antimilitaristisch-feministische Bündnisse und Bündisarbeit als kontingente, soziale Prozesse
Creators: name: Leidinger, Christiane
Publisher: name: Österreichische Zeitschrift für Politikwissenschaft
Year: 2015

description: Die ersten der elf „Frauenwiderstandscamps“ im Hunsrück (BRD), die seit 1983 stattfanden, waren erstaunlich weitgreifende politische Bündnisse von Feministinnen gegen Militarismus und Männergewalt. An deren Beispiel lässt sich die für Koalitionen notwendige gemeinsame Bündnisarbeit (u.a. Entwicklung von Verfahren zur Konfliktlösung als Teil eines institutionellen Arrangements) im Rahmen eines kontingenten sozialen Prozesses verdeutlichen. Dabei stellt sich heraus, dass politisches Camping mehr ist als ein Mittel zum Zweck eines Vor-Ort-Protests, da sich das Zusammenleben auf den Camps in verschiedener Hinsicht als Bündnismotor erweist. Hier zeigt sich die strukturelle Signifikanz von Camps als offenes, politisches Laboratorium, als Utopieforum, als temporäre, reflexive Organisations-, Mobilisierungs-, Partizipations-, Handlungs- und Protestformen – auch und gerade für politisch breite Bündnisse. Die frühen Frauenwiderstandscamps im Hunsrück weisen spezifische (auch feministische) Kennzeichen und Kriterien auf, die mit den bestehenden bündnistheoretischen Überlegungen bislang nicht oder nicht hinreichend beschrieben werden konnten.

description: A spin-$j$ state can be represented by a symmetric tensor of order $N=2j$ and dimension $4$. Here, $j$ can be a positive integer, which corresponds to a boson; $j$ can also be a positive half-integer, which corresponds to a fermion. In this paper, we introduce regularly decomposable tensors and show that a spin-$j$ state is classical if and only if its representing tensor is a regularly decomposable tensor. In the even-order case, a regularly decomposable tensor is a completely decomposable tensor but not vice versa; a completely decomposable tensors is a sum-of-squares (SOS) tensor but not vice versa; an SOS tensor is a positive semi-definite (PSD) tensor but not vice versa. In the odd-order case, the first row tensor of a regularly decomposable tensor is regularly decomposable and its other row tensors are induced by the regular decomposition of its first row tensor. We also show that complete decomposability and regular decomposability are invariant under orthogonal transformations, and that the completely decomposable tensor cone and the regularly decomposable tensor cone are closed convex cones. Furthermore, in the even-order case, the completely decomposable tensor cone and the PSD tensor cone are dual to each other. The Hadamard product of two completely decomposable tensors is still a completely decomposable tensor. Since one may apply the positive semi-definite programming algorithm to detect whether a symmetric tensor is an SOS tensor or not, this gives a checkable necessary condition for classicality of a spin-$j$ state. Further research issues on regularly decomposable tensors are also raised.

description: Fads, product adoption, mobs, rumors, memes, and emergent norms are diverse social contagions that have been modeled as network cascades. Empirical study of these cascades is vulnerable to what we describe as the "opacity problem": the inability to observe the critical level of peer influence required to trigger an individual's behavioral change. Even with maximal information, network cascades reveal intervals that bound critical levels of peer exposure, rather than critical values themselves. Existing practice uses interval maxima, which systematically over-estimates the social influence required for behavioral change. Simulations reveal that the over-estimation is likely common and large in magnitude. This is confirmed by an empirical study of hashtag cascades among 3.2 million Twitter users: one in five hashtag adoptions suffers critical value uncertainty due to the opacity problem. Different assumptions about these intervals lead to qualitatively different conclusions about the role of peer reinforcement in diffusion. We introduce a solution that combines identifying tightly bounded intervals with predicting uncertain critical values using node-level information.

description: The effect of spatial localization of states in distributed parameter systems under frozen parametric disorder is well known as the Anderson localization and thoroughly studied for the Schrödinger equation and linear dissipation-free wave equations. Some similar (or mimicking) phenomena can occur in dissipative systems such as the thermal convection ones. Specifically, many of these dissipative systems are governed by a modified Kuramoto-Sivashinsky equation, where the frozen spatial disorder of parameters has been reported to lead to excitation of localized patterns. Imposed advection in the modified Kuramoto-Sivashinsky equation can affect the localized patterns in a nontrivial way; it changes the localization properties and suppresses the pattern. The latter effect is considered in this paper by means of both numerical simulation and model reduction, which turns out to be useful for a comprehensive understanding of the bifurcation scenarios in the system. Two possible bifurcation scenarios of advective suppression ("washing-out") of localized patterns are revealed and characterised.

description: Plasma wake-field acceleration is one of the main technologies being developed for future high-energy colliders. Potentially, it can create a cost-effective path to the highest possible energies for e+e- or γ-γ colliders and produce a profound effect on the developments for high-energy physics. Acceleration in a blowout regime, where all plasma electrons are swept away from the axis, is presently considered to be the primary choice for beam acceleration. In this paper, we derive a universal efficiency-instability relation, between the power efficiency and the key instability parameter of the trailing bunch for beam acceleration in the blowout regime. We also show that the suppression of instability in the trailing bunch can be achieved through BNS damping by the introduction of a beam energy variation along the bunch. Unfortunately, in the high efficiency regime, the required energy variation is quite high, and is not presently compatible with collider-quality beams. We would like to stress that the development of the instability imposes a fundamental limitation on the acceleration efficiency, and it is unclear how it could be overcome for high-luminosity linear colliders. With minor modifications, the considered limitation on the power efficiency is applicable to other types of acceleration.

description: Während die Immigrationspolitiken von OECD-Staaten in der Forschung bisher viel Aufmerksamkeit fanden, fehlen bisher Analysen, die sich mit der Entwicklung von Visumpolitiken über die Zeit beschäftigen. Dieser Artikel trägt dazu bei, dieses Defizit zu beheben. Wir analysieren die Visumpolitiken der USA und Österreichs im Hinblick auf Kurzzeitreisen. Durch Österreichs EU-Beitritt im Jahre 1995 erfasst unsere Untersuchung nicht nur die österreichische Visumpolitik, sondern auch den Beginn und die Entwicklung der EU-Politik in diesem Feld. Mit dieser Fallauswahl konzentrieren wir uns nicht nur auf zwei beliebte touristische Reiseziele der Welt, sondern, wenn man die Harmonisierung der Visumpolitik in der EU mitbedenkt, auch ab 1995 auf die zwei wichtigsten ökonomischen Regionen innerhalb der OECD. Wir zeigen, dass Bürger aus wohlhabenden Demokratien eher in den Genuss von Visumerleichterungen kamen als solche aus anderen Ländern. Über die Zeit verstärkte sich dieser Zusammenhang und führte zu einer zunehmenden Selektivität bei der Auswahl von „erwünschten“ und „unerwünschten“ Reisenden. Zusätzlich wuchs die Übereinstimmung zwischen den Visumregimen der USA und Österreichs/der EU seit den 1990er- Jahren.

description: We show that abstract Cuntz semigroups form a closed symmetric monoidal category. Thus, given Cuntz semigroups $S$ and $T$, there is another Cuntz semigroup $[[S,T]]$ playing the role of morphisms from $S$ to $T$. Applied to C$^*$-algebras $A$ and $B$, the semigroup $[[\mathrm{Cu}(A),\mathrm{Cu}(B)]]$ should be considered as the target in analogues of the UCT for bivariant theories of Cuntz semigroups. Abstract bivariant Cuntz semigroups are computable in a number of interesting cases. We also show that order-zero maps between C$^*$-algebras naturally define elements in the respective bivariant Cuntz semigroup.

description: The sensitivities to the anomalous quartic gauge boson coupling $γγγZ$ are estimated via $γZ$ production with intact protons in the forward region at the LHC. Proton tagging proves to be a powerful tool to suppress the background, which allows consideration of the hadronic decays of the $Z$ boson in addition to the leptonic ones. We discuss the discovery potential for an integrated luminosity of $300\,\mathrm{fb}^{-1}$ and $3000\,\mathrm{fb}^{-1}$. The sensitivity we obtain at $300\,\mathrm{fb}^{-1}$ goes beyond the one expected from LHC bounds on the $Z\rightarrow γγγ$ decay by about three orders of magnitude. The $γZ$ channel provides important discriminatory information with respect to the exclusive $γγ$ channel, as many particles beyond the Standard Model (such as a radion or Kaluza Klein gravitons) predict a signal in the latter but not the former.

description: Ziel dieser Arbeit ist die Untersuchung von Bestimmungsgründen für die Akzeptanz von sozial- und wirtschaftspolitischen Maßnahmen in der österreichischen Bevölkerung. Insbesondere wird die Rolle der Faktoren Eigeninteresse, politische Ideologie und Wissen untersucht. Vor allem die Berücksichtigung von Unterschieden im Wissensstand in der Bevölkerung stellt ein Novum dieser Arbeit im Vergleich zu bisherigen Studien dar. Auf Basis einer repräsentativen Umfrage weisen die Ergebnisse der Studie darauf hin, dass das Eigeninteresse als Determinante der Akzeptanz im Vordergrund steht. Bei Personen mit einem hohen wirtschaftlichen Wissensstand drückt sich die Relevanz des Eigeninteresses verstärkt durch die subjektive Betroffenheit aus. Bei Personen mit geringerem Wissen manifestiert sich das Eigeninteresse eher durch politisch/ideologische Positionierungen.

description: In this paper, we study the singularities of locally flat systems, motivated by the solution, if it exists, of the global motion planning problem for such systems, in the spirit of \cite{CE_14}. More precisely, flat outputs may be only locally defined because of the existence of points where they are singular (a notion that will be made clear later), thus preventing from planning trajectories crossing these points. Such points are of different types. Some of them can be easily ruled out by considering another non singular flat output, defined on an open set intersecting the domain of the former one and well defined at the point in question. However, it might happen that no well-defined flat outputs exist at all at some points. We call these points \emph{intrinsic} singularities and the other ones \emph{apparent}. A rigorous defintion of these points is introduced in terms of atlas and charts in the framework of the differential geometry of jets of infinite order and Lie-Bäcklund isomorphisms (see \cite{FLMR_99,Levine-09}). We then give a criterion allowing to effectively compute intrinsic singularities. Finally, we show how our results apply to global motion planning of the well-known example of non holonomic car.

description: High-energy jets recoiling against missing transverse energy (MET) are powerful probes of dark matter at the LHC. Searches based on large MET signatures require a precise control of the $Z(ν\barν)+$jet background in the signal region. This can be achieved by taking accurate data in control regions dominated by $Z(\ell^+\ell^-)+$jet, $W(\ellν)+$jet and $γ+$jet production, and extrapolating to the $Z(ν\barν)+$jet background by means of precise theoretical predictions. In this context, recent advances in perturbative calculations open the door to significant sensitivity improvements in dark matter searches. In this spirit, we present a combination of state-of-the art calculations for all relevant $V+$jets processes, including throughout NNLO QCD corrections and NLO electroweak corrections supplemented by Sudakov logarithms at two loops. Predictions at parton level are provided together with detailed recommendations for their usage in experimental analyses based on the reweighting of Monte Carlo samples. Particular attention is devoted to the estimate of theoretical uncertainties in the framework of dark matter searches, where subtle aspects such as correlations across different $V+$jet processes play a key role. The anticipated theoretical uncertainty in the $Z(ν\barν)+$jet background is at the few percent level up to the TeV range.

description: With the development of deep learning, supervised learning has frequently been adopted to classify remotely sensed images using convolutional networks (CNNs). However, due to the limited amount of labeled data available, supervised learning is often difficult to carry out. Therefore, we proposed an unsupervised model called multiple-layer feature-matching generative adversarial networks (MARTA GANs) to learn a representation using only unlabeled data. MARTA GANs consists of both a generative model $G$ and a discriminative model $D$. We treat $D$ as a feature extractor. To fit the complex properties of remote sensing data, we use a fusion layer to merge the mid-level and global features. $G$ can produce numerous images that are similar to the training data; therefore, $D$ can learn better representations of remotely sensed images using the training data provided by $G$. The classification results on two widely used remote sensing image databases show that the proposed method significantly improves the classification performance compared with other state-of-the-art methods.

description: Let R be a commutative noetherian ring. We give criteria for a complex of cotorsion flat R-modules to be minimal, in the sense that every self homotopy equivalence is an isomorphism. To do this, we exploit Enochs' description of the structure of cotorsion flat R-modules. More generally, we show that any complex built from covers in every degree (or envelopes in every degree) is minimal, as well as give a partial converse to this in the context of cotorsion pairs. As an application, we show that every R-module is isomorphic in the derived category over R to a minimal semi-flat complex of cotorsion flat R-modules.

description: The goal of the studies I describe in this thesis is to better understand how the cellular proteome responds to Hepatitis B Virus (HBV) infection and identify potential therapeutic targets. I used a cellular HBV replication model and performed proteomic analyses to understand how HBV evades innate immunity as a function of cell cycle progression. I identified that the conserved LSm (Like-Sm1-8) proteins were differentially regulated in HBV replicating cells treated with IFN-α. Specifically, in the G2/M phase, IFN-α increased protein level of LSm1, the unique subunit of the cytoplasmic LSm1-7 complex involved in mRNA decay. By contrast, IFN-α decreased LSm8, the unique subunit of the nuclear LSm2-8 complex, a chaperone of U6 spliceosomal RNA. These studies determined that the cytoplasmic LSm1-7 complex is antiviral, whereas the nuclear LSm2-8 complex is pro-viral. Mechanistic studies also led to the identification of the splicing inhibitor Cp028, acting upstream of the LSm2-8 complex, as an inhibitor of viral RNA levels and a potential anti-HBV compound. In the second part of my dissertation, I aimed to identify alternate approaches to silence viral transcription in chronic HBV infection. Despite the availability of potent antivirals, complete elimination of the viral minichromosome (cccDNA), the template of viral transcription, is unsuccessful resulting in viral persistence. Earlier studies showed that the RNA helicase DDX5 restricts HBV biosynthesis by an unknown mechanism. I performed proteomic studies to search for DDX5 interacting proteins. I identified Interferon gamma inducible protein 16 (IFI16), as the most prominent DDX5-interacting protein. Employing size exclusion chromatography (SEC) of native nuclear extracts in combination with LC-MS/MS of SEC fractions and various functional assays, I demonstrated that DDX5 and IFI16 form a large (750-350 KDa), RNA-dependent epigenetic silencing complex. Although the identity of this RNA remains to be determined, my studies conclusively demonstrate that DDX5 represses cccDNA-driven viral transcription by forming this RNA-dependent complex with IFI16, in association with the epigenetic silencing Polycomb Repressive Complex 2(PRC2). Importantly, this DDX5/IFI16/PRC2/RNA complex mediates the transcription silencing modifications of the HBV minichromosome in response to Interferon-α. I conclude that DDX5 downregulation is a pro-viral factor in HBV biosynthesis. Overall, this dissertation work provides new insights into the interaction between HBV and the host proteome and identifies potential targets for the development of more effective therapies for the treatment of HBV infection.

description: The ability to effectively control brain dynamics holds great promise for the enhancement of cognitive function in humans, and the betterment of their quality of life. Yet, successfully controlling dynamics in neural systems is challenging, in part due to the immense complexity of the brain and the large set of interactions that can drive any single change. While we have gained some understanding of the control of single neurons, the control of large-scale neural systems -- networks of multiply interacting components -- remains poorly understood. Efforts to address this gap include the construction of tools for the control of brain networks, mostly adapted from control and dynamical systems theory. Informed by current opportunities for practical intervention, these theoretical contributions provide models that draw from a wide array of mathematical approaches. We present intriguing recent developments for effective strategies of control in dynamic brain networks, and we also describe potential mechanisms that underlie such processes. We review efforts in the control of general neurophysiological processes with implications for brain development and cognitive function, as well as the control of altered neurophysiological processes in medical contexts such as anesthesia administration, seizure suppression, and deep-brain stimulation for Parkinson's disease. We conclude with a forward-looking discussion regarding how emerging results from network control -- especially approaches that deal with nonlinear dynamics or more realistic trajectories for control transitions -- could be used to directly address pressing questions in neuroscience.
