description: When some 'entities' are related by the 'features' they share they are amenable to a bipartite network representation. Plant-pollinator ecological communities, co-authorship of scientific papers, customers and purchases, or answers in a poll, are but a few examples. Analyzing clustering of such entities in the network is a useful tool with applications in many fields, like internet technology, recommender systems, or detection of diseases. The algorithms most widely applied to find clusters in bipartite networks are variants of modularity optimization. Here we provide an hierarchical clustering algorithm based on a dissimilarity between entities that quantifies the probability that the features shared by two entities is due to mere chance. The algorithm performance is $O(n^2)$ when applied to a set of n entities, and its outcome is a dendrogram exhibiting the connections of those entities. Through the introduction of a 'susceptibility' measure we can provide an 'optimal' choice for the clustering as well as quantify its quality. The dendrogram reveals further useful structural information though -- like the existence of sub-clusters within clusters or of nodes that do not fit in any cluster. We illustrate the algorithm by applying it first to a set of synthetic networks, and then to a selection of examples. We also illustrate how to transform our algorithm into a valid alternative for one-mode networks as well, and show that it performs at least as well as the standard, modularity-based algorithms -- with a higher numerical performance. We provide an implementation of the algorithm in Python freely accessible from GitHub.

title: The role of SCL in haematopoiesis and leukaemogenesis
Creators: name: Schuh, Annette Hildegard
Publisher: name: The Open University
Year: 2005

description: The fundamental question of how restriction of differentiation potential and activation of lineage-specific gene expression in progenitor cells are regulated is at the heart of research into the molecular mechanisms of biology. The basic helix-loop-helix (bHLH) transcription factor SCL/TAL-1 serves as a paradigm for a transcription factor with pivotal roles in haematopoietic stem cell (HSC) specification, maturation of haematopoietic lineages as well as T-cell leukaemogenesis. Interestingly, it has been described as both a transcriptional activator and a repressor. However, the molecular mechanisms conferring these opposing functions are currently unknown.

As a first step towards characterising the role of SCL in haematopoiesis and leukaemogenesis, we performed a gain-of-function study using a transgenic mouse model over-expressing SCL. Although no leukaemia was observed, constitutive expression of SCL or a mutant lacking the DNA binding domain in HSCs and early progenitors caused a severe defect in T- and B-lymphopoiesis. This was likely due to an interaction with the important lymphoid regulator and SCL heterodimerisation partner E2A.

Then, we set up a proteomics strategy to identify protein partners of SCL in haematopoiesis. We isolated SCL-containing protein complexes in erythroid cells and megakaryocytes using a novel purification strategy based on in vivo biotinylation of SCL. Mass spectrometry analysis led to the identification of several previously unknown candidate partners including ETO-2, a member of the ETO family of co-repressor proteins and SSDP2, a partner of LDB-1. Using several different approaches, we validated the SCL/ETO-2 interaction in cell lines as well as primary erythrocytes and megakaryocytes. We then identified Gfi-1 b, a critical regulator of erythropoiesis with repressive function and the co-repressor mSin3A as additional partners of SCL and ETO-2 in erythroid cells, but not megakaryocytes. Further characterisation in transactivation experiments and during in vitro differentiation of primary fetal liver cells led us to hypothesise that, in early erythropoiesis, ETO-2 might confer a repressive function to SCL.

In conclusion, this study gives a first insight into how the composition of the multimeric protein complexes including SCL might modulate haematopoietic differentiation and cell fate decision.
A Bloch-Sphere-Type Model for Two Qubits in the Geometric Algebra of a 6-D Euclidean Vector Space

description: Geometric algebra is a mathematical structure that is inherent in any metric vector space, and defined by the requirement that the metric tensor is given by the scalar part of the product of vectors. It provides a natural framework in which to represent the classical groups as subgroups of rotation groups, and similarly their Lie algebras. In this article we show how the geometric algebra of a six-dimensional real Euclidean vector space naturally allows one to construct the special unitary group on a two-qubit (quantum bit) Hilbert space, in a fashion similar to that used in the well-established Bloch sphere model for a single qubit. This is then used to illustrate the Cartan decompositions and subalgebras of the four-dimensional special unitary group, which have recently been used by J. Zhang, J. Vala, S. Sastry and K. B. Whaley [Phys. Rev. A 67, 042313, 2003] to study the entangling capabilities of two-qubit unitaries.

description: Reflection electron energy loss spectroscopy (EELS) in specular and off specular geometry has been employed to study the early stage of the copper phthalocyanine (CuPc) growth on Al (100) substrate. EEL spectroscopy has been a useful tool in order to study electronic structure of molecular films also in the submonolayer regime. The electronic structure of the first deposited layer of CuPc is strongly influenced by charge transfer from the Al substrate to the lowest unoccupied molecular orbital (LUMO). The strong molecule-substrate interaction gives rise to a coverage dependent frequency shift of the Al surface plasmon. Successive layers have essentially the electronic structure of the molecular solid. Momentum resolved EELS measurements reveal that, in the case of the thicker film investigated (22 Å), the plane of the molecule is almost perpendicular to the surface of the substrate.

description: A number of events of terrorist nature and disasters in the early 21st century resulted in enhancing the role of security in many areas of social and business life, including also those concerning the functioning of businesses. The execution of corporate social responsibility (CSR) premises in the context of ensuring ecological security is reflected in many management approaches and concepts. The objective of this paper is the presentation of relationships of ecological security with various management concepts which take CSR premises into consideration. As a research method, the critical analysis of the existing theoretical concepts related to ecological security issues and the CSR concept has been assumed. Then, the connections of these concepts in the executed business models taking into account the process approach and creating the value of the business based on ecological criteria was analysed.

description: By analyzing legal rules and political practice, the aim of this thesis has been to show that the quest of member states of the European Union to regain sovereignty may be legally possible, but at the same time, seems politically unthinkable. Within this framework, at first we presented the means, that member states have at their disposal in order to rescind from the european project, by voluntarily withdrawing from the EU, by exiting the eurozone or by dissoluting the Union itself. Furthermore, we analyzed the ways that EU membership can be affected by changes taking place within member states, examining the possibility of a succession scenario involving at least one member state, the threats recently posed to EU values in Hungary and Poland and the possibility that some member states become unable to fulfil their obligations towards the EU.

description: In the weak-coupling regime of the continuous theories, two sets of one-loop renormalization group equations are derived and solved to disclose the phase diagrams of the antiferromagnetic generalized two-leg spin-1/2 ladder under the effect of (I) a staggered external magnetic field and (II) an explicit dimerization. In model (I), the splitting of the SU(2)$_2$ critical line into U(1) and Z$_2$ critical surfaces is observed; while in model (II), two critical surfaces arising from their underlying critical lines with SU(2)$_2$ and Z$_2$ characteristics merge into an SU(2)$_1$ critical surface on the line where the model attains its highest symmetry.

Algebraic Extension Ring Framework for Non-Commutative Asymmetric Cryptography

description: Post-Quantum Cryptography (PQC) attempts to find cryptographic protocols resistant to attacks using Shor’s polynomial time algorithm for numerical field problems or Grover’s algorithm to find the unique input to a black-box function that produces a particular output value. The use of non-standard algebraic structures like non-commutative or non-associative structures, combined with one-way trapdoor functions derived from combinatorial group theory, are mainly unexplored choices for these new kinds of protocols and overlooked in current PQC solutions. In this paper, we develop an algebraic extension ring framework who could be applied to different asymmetric protocols (i.e. key exchange, key transport, enciphering, digital signature, zero-knowledge authentication, oblivious transfer, secret sharing etc.). A valuable feature is that there is no need for big number libraries as all arithmetic is performed in extension field operations (precisely the AES field). We assume that the new framework is cryptographical secure against strong classical attacks like the sometimes-useful length-based attack, Roman’kov’s linearization attacks and Tsaban’s algebraic span attack. This statement is based on the non-linear structure of the selected platform which proved to be useful protecting the AES protocol. Otherwise, it could resist post-quantum attacks (Grover, Shor) and be particularly useful for computational platforms with limited capabilities like USB cryptographic keys or smartcards. Semantic security (IND-CCA2) could also be inferred for this new platform.

description: We discuss materials based on arrays of metallic magnetic cylindrical structures near ferromagnetic resonance with applied magnetic fields at microwave frequencies. We have found that the materials have a negative refraction index when the appropriate structure is chosen. Numerical FDTD simulations were performed, after a very large number of geometries were swept. The simulations reveal that only ferromagnetic cylinders, with diameters of 0.1 cm and 0.5 cm apart, and with periodic or random configurations, are left-handed materials with very small losses; i.e. with transmitivity practically unity or no losses.

description: Mpemba effect refers to the counterintuitive result that, when quenched to a low temperature, a system at higher temperature may equilibrate faster than one at intermediate temperatures. This effect has recently been demonstrated in driven granular gases, both for smooth as well as rough hard-sphere systems based on a perturbative analysis. In this paper, we consider the inelastic driven Maxwell gas, a simplified model for a granular gas, where the rate of collision is assumed to be independent of the relative velocity. Through an exact analysis, we determine the conditions under which a Mpemba effect is present in this model. For mono-dispersed gases, we show that the Mpemba effect is present only when the initial states are allowed to be non-stationary, while for bi-dispersed gases, it is present for steady state initial states. We also demonstrate the existence of the strong Mpemba effect for bi-dispersed Maxwell gas wherein the system at higher temperature relaxes to a final steady state at an exponentially faster rate leading to smaller equilibration time.

description: This paper estimates the relative risk of drunk-drivers causing a fatal accident using imputed values for BAC from the Fatality Analysis Reporting System for three time periods. In addition, we develop an econometric approach that allows the decomposition of fatal accident risk into two components: the relative probability of a drunk-driver causing a serious accident and the probability of dying in a serious accident. Our results suggest that the relative risk of drunk drivers causing a fatal accident increased by approximately one-third from 1983-1993 to 2004- 2013. Further, the increase in relative risk was caused almost entirely by an increase in the relative risk of drunk drivers causing a serious accident. In contrast, the relative risk of a drunk driver dying in a serious accident was nearly unchanged. We also find that there has been a decrease in the incidence of drunk driving, as well as the external cost associated with drunkdriving.

description: Data with uncertain, missing, censored, and correlated values are commonplace in many research fields including astronomy. Unfortunately, such data are often treated in an ad hoc way in the astronomical literature potentially resulting in inconsistent parameter estimates. Furthermore, in a realistic setting, the variables of interest or their errors may have non-normal distributions which complicates the modeling. I present a novel approach to compute the likelihood function for such data sets. This approach employs Gaussian copulas to decouple the correlation structure of variables and their marginal distributions resulting in a flexible method to compute likelihood functions of data in the presence of measurement uncertainty, censoring, and missing data. I demonstrate its use by determining the slope and intrinsic scatter of the star forming sequence of nearby galaxies from observational data. The outlined algorithm is implemented as the flexible, easy-to-use, open-source Python package LEO-Py.

description: Observational data for the hourglass-like magnetic field toward the starless dense core FeSt 1-457 were compared with a flux freezing magnetic field model (Myers et al. 2018). Fitting of the observed plane-of-sky magnetic field using the flux freezing model gave a residual angle dispersion comparable with the results based on a simple three-dimensional parabolic model. The best-fit parameters for the flux freezing model were a line-of-sight magnetic inclination angle of $γ_{\rm mag} = 35^{\circ} \pm 15^{\circ}$ and a core center to ambient (background) density contrast of $ρ_{\rm c} / ρ_{\rm bkg} = 75$. The initial density for core formation ($ρ_0$) was estimated to be $ρ_{\rm c} / 75 = 4670$ cm$^{-3}$, which is about one order of magnitude higher than the expected density ($\sim 300$ cm$^{-3}$) for the inter-clump medium of the Pipe Nebula. FeSt 1-457 is likely to have been formed from the accumulation of relatively dense gas, and the relatively dense background column density of $A_V \simeq 5$ mag supports this scenario. The initial radius (core formation radius) $R_0$ and the initial magnetic field strength $B_0$ were obtained to be 0.15 pc ($1.64 R$) and $10.8-14.6$ $μ$G, respectively. We found that the initial density $ρ_0$ is consistent with the mean density of the nearly critical magnetized filament with magnetic field strength $B_0$ and radius $R_0$. The relatively dense initial condition for core formation can be naturally understood if the origin of the core is the fragmentation of magnetized filaments.

As the $B$ strength is increased superconductivity degrades, until a critical field ($B_c$) where the system is forced into an insulating state. We show that the differential conductance measured in the insulating phase vanishes abruptly below a well-defined temperature, resulting in a clear threshold for conduction. Our results indicate that a new collective state emerges in two-dimensional superconductors at high $B$.

description: Lifecycle analysis is one of the techniques for assessing the impact of enterprise on the environment, by monitoring environmental effects of the product along its lifecycle. Since the cycle can be seen in stages (extraction of raw materials, raw materials processing, final product production, product use and end of use of the product), the analysis can be applied to all or only some parts of the aforementioned cycle, hence the different variants of this technique. The analysis itself is defined in phases according to the of ISO 14040 standard series, and involves defining the objectives and scope of analysis, life cycle inventory data analysis, life cycle impact assessment and lifecycle interpretation. Although its use is characterized by certain disadvantages, it can be said that this is still a very valuable management tool without which one cannot imagine the process of effective environmental decision-making in the modern enterprise, and consequently the complete adoption of environmentally responsible way of doing business.

description: We report the results of a photometric and spectroscopic survey for planetary nebulae (PNe) in the Local Group spiral galaxy M33. We use our sample of 152 PNe to derive an [O III] planetary nebula luminosity function (PNLF) distance of (m-M)_0 = 24.86^+0.07-0.11 (0.94^+0.03-0.05 Mpc). Although this value is ~ 15% larger than the galaxy's Cepheid distance, the discrepancy likely arises from differing assumptions about the system's internal extinction. Our photometry (which extends >3 mag down the PNLF), also reveals that the faint-end of M33's PN luminosity function is non-monotonic, with an inflection point ~2 mag below the PNLF cutoff. We argue that this feature is due to the galaxy's large population of high core-mass planetaries, and that its amplitude may eventually be useful as a diagnostic for studies of stellar populations. Fiber-coupled spectroscopy of 140 of the PN candidates confirms that M33's PN population rotates along with the old disk, with a small asymmetric drift of \~ 10km/s. Remarkably, the population's line-of-sight velocity dispersion varies little over ~4 optical disk scale lengths, with sigma_{rad}~20km/s. We show that this is due to a combination of factors, including a decline in the radial component of the velocity ellipsoid at small galactocentric radii, and a gradient in the ratio of the vertical to radial velocity dispersion. We use our data to show that the mass scale length of M33's disk is ~2.3 times larger than that of the system's IR luminosity and that the disk's V-band mass-to-light ratio changes from M/L_V ~0.3 in the galaxy's inner regions to M/L_V ~2.0 at ~9 kpc. Models in which the dark matter is distributed in the plane of the galaxy are excluded by our data. (abridged)

description: Large $N$ matrix quantum mechanics is central to holographic duality but not solvable in the most interesting cases. We show that the spectrum and simple expectation values in these theories can be obtained numerically via a `bootstrap' methodology. In this approach, operator expectation values are related by symmetries -- such as time translation and $SU(N)$ gauge invariance -- and then bounded with certain positivity constraints. We first demonstrate how this method efficiently solves the conventional quantum anharmonic oscillator. We then reproduce the known solution of large $N$ single matrix quantum mechanics. Finally, we present new results on the ground state of large $N$ two matrix quantum mechanics.

description: We present a characterization of one-component inner functions in terms of the location of their zeros and their associated singular measure. As consequence we answer several questions posed by J. Cima and R. Mortini. In particular we prove that for any inner function $Θ$ whose singular set has measure zero, one can find a Blaschke product $B$ such that $ΘB$ is one-component. We also obtain a characterization of one-component singular inner functions which is used to produce examples of discrete and continuous one-component singular inner functions.

Scaling of the magnetic response in doped antiferromagnets

description: A theory of the anomalous $ω/T$ scaling of the dynamic magnetic response in cuprates at low doping is presented. It is based on the memory function representation of the dynamical spin suceptibility in a doped antiferromagnet where the damping of the collective mode is constant and large, whereas the equal-time spin correlations saturate at low $T$. Exact diagonalization results within the t-J model are shown to support assumptions. Consequences, both for the scaling function and the normalization amplitude, are well in agreement with neutron scattering results.

title: Good and Bad Women in the Bible
Creators: name: Nixon, Naomi Jane
Publisher: name: The Open University
Year: 2005

description: This study considers the division of women in the Bible into either ‘Good’ or ‘Bad’. This dichotomy obscures the fact that real women are a mixture of good and bad, and thus female readers of the Bible are denied realistic female role models and may be perceived as either ‘Good’ or ‘Bad’ in the same way that biblical women are. Four women who display elements of this trend are analysed in detail, both in their stories and in the interpretation of those stories. Ruth in is a heroine in her story and clearly her role must be that of a ‘Good’ woman. However, the demands of the ‘Good’ and ‘Bad’ woman dichotomy mean she is cast as pure and unphysical since she is good. Her extraordinary assertiveness is reread as loyalty, her sexual forwardness becomes innocent obedience, and her pragmatism is interpreted as faith. Gomer, wife of the prophet Hosea, is confused with Israel, the errant wife of God, in both the text and in commentary on it. Her own story is stifled as a result, and her humanity is exchanged for symbolism. Her guilt is paraded, while her extraordinary husband is compared to God. Jephthah’s daughter is the nameless child who is sacrificed to complete a bargain. She is an unusual heroine but nevertheless her silence is ealled obedience and her death is celebrated as a national festival, yet her name is forgotten. Delilah is the villainess of Samson’s story who defeats this strong leader from Israel and hence is a ‘Bad’ woman. Delilah’s victory seals her reputation: her frank questioning is called wily; her nationality is assumed to be that of the enemy and she is cast as the seductress extraordinaire, even though the text is silent about her sexuality. The polarised conclusions of commentators analysed in this study are shown often to be simplistic or far-fetched. The study concludes by asserting the belief that the acknowledgement of the complex nature of these biblical women would help Christian women accept the complexities within themselves.

The transition to adulthood in adolescents and young adults with Marfan Syndrome : a scoping review
Creators: name: Ng, Tiffany Anne
Publisher: name: The University of British Columbia
Year: 2018

description: BACKGROUND: In healthcare, one type of transition is the planned movement of adolescents or young adults with chronic conditions from the pediatric health care system to the adult one. During this time, there is a high risk for these individuals to be lost to follow-up. Patients with Marfan Syndrome (MFS), a potentially life-threatening genetic condition, are one group that is subject to this risk. With improving life expectancy, an organized transition process is needed to prepare adolescents and young adults for the challenges of both adulthood and their condition. Nurses can be key players in facilitating this process. OBJECTIVES: 1) To map the range of evidence on the transition process for patients with MFS, as identified in both peer-reviewed and grey literature; 2) to examine the concepts and themes of transition discussed in the literature for patients with MFS; and 3) to identify gaps in the current literature and draw recommendations from another chronic condition, specifically congenital heart disease (CHD), to determine areas for further research. METHODS: Four databases and grey literature were searched for English publications published between 2003 and 2018, focusing on adolescents or young adult patients with MFS or CHD during transition. RESULTS: Thirty-one publications (24 research articles, 7 websites) met the inclusion criteria with the majority of the literature originating in North America (n = 20). Schumacher and Meleis’ 1994 transition framework guided the analysis of the literature. Twenty-seven publications (87%) provided a definition of transition and the level of planning was the most commonly discussed factor affecting transition. However, indicators of healthy transition were rarely measured. A thematic analysis revealed four components of the transition process: the need for knowledge and skills; the impact of parental involvement; preparing and planning for the future; and the transition readiness of the adolescent or young adult. CONCLUSION: The existing literature highlights that the transition process is important in the transition of adolescents and young adults with chronic conditions to adulthood; however, a gap is evident in our knowledge of this process for patients with MFS. Further research in this area is indicated to identify the needs of MFS patients and to test interventions to facilitate a smooth transition to adulthood.

description: An MN-Gallager Code over Galois fields, $q$, based on the Dynamical Block Posterior probabilities (DBP) for messages with a given set of autocorrelations is presented with the following main results: (a) for a binary symmetric channel the threshold, $f_c$, is extrapolated for infinite messages using the scaling relation for the median convergence time, $t_{med} \propto 1/(f_c-f)$; (b) a degradation in the threshold is observed as the correlations are enhanced; (c) for a given set of autocorrelations the performance is enhanced as $q$ is increased; (d) the efficiency of the DBP joint source-channel coding is slightly better than the standard gzip compression method; (e) for a given entropy, the performance of the DBP algorithm is a function of the decay of the correlation function over large distances.
