title: Decostruire il terrore. L’evento senza sovranità
Creators: name: Saffioti , Francesca
Publisher: name: Roma Tre-Press
Year: 2006

description: Del terrore si deve dire che è l'inatteso, ma non necessariamente il "nuovo". Il terrore in qualche modo presenta qualcosa che ci è familiare. Il terrore non è suscitato da un attacco che proviene dall'esterno. Esso non sarà mai abbastanza potente da mettere in discussione il monopolio della forza. Qualcosa di inquietante si agita piuttosto laddove le categorie politiche manifestano la loro crisi e il linguaggio si affida alla ripetizione di parole svuotate di un significato effettivo.

description: The paper presents a suspicious email detection model which incorporates enhanced feature selection. In the paper we proposed the use of feature selection strategies along with classification technique for terrorists email detection. The presented model focuses on the evaluation of machine learning algorithms such as decision tree (ID3), logistic regression, Naïve Bayes (NB), and Support Vector Machine (SVM) for detecting emails containing suspicious content. In the literature, various algorithms achieved good accuracy for the desired task. However, the results achieved by those algorithms can be further improved by using appropriate feature selection mechanisms. We have identified the use of a specific feature selection scheme that improves the performance of the existing algorithms.

description: We present a study on the dependency parsing of second language learner data, focusing less on the parsing techniques and more on the effect of the linguistic distinctions made in the data. In particular, we examine syntactic annotation that relies more on morphological form than on meaning. We see the effect of particular linguistic decisions by: 1) converting and transforming a training corpus with a similar annotation scheme, with transformations occurring either before or after parsing; 2) inputting different kinds of part-of-speech (POS) information; and 3) analyzing the output. While we see a general favortism for parsing with more local dependency relations, this seems to be less the case for parsing the data of lower-level learners.
Zeeman shift of an electron trapped near a surface

description: Boundary dependent corrections to the spin energy eigenvalues of an electron in a weak magnetic field and confined by a harmonic trapping potential are investigated. The electromagnetic field is quantized through a normal mode expansion obeying the Maxwell boundary conditions at the material surface. We couple the electron to this photon field and a classical magnetic field in the Dirac equation, to which we apply the unitary Foldy-Wouthuysen transformation in order to generate a non-relativistic approximation of the Hamiltonian to the desired order. We obtain the Schrödinger eigenstates of an electron subject to double confinement by a harmonic potential and a classical magnetic field, and then use these within second-order perturbation theory to calculate the spin energy shift that is attributable to the surface-modified quantized field. We find that a pole at the eigenfrequency of a set of generalized Landau transitions gives dominant oscillatory contributions to the energy shift in the limit of tight harmonic confinement in a weak magnetic field, which also make the energy shift preferable to the magnetic moment for a physically meaningful interpretation.

CENP-A
Mis18 complex
HJURP

description: Centromeres are epigenetically defined by the histone H3 variant, CENPA, which is crucial for faithful chromosome segregation and genome stability. CENP-A is distributed equally to sister chromatids during DNA replication in the S phase necessitating CENP-A replenishment in each round of the cell cycle. CENP-A deposition is initiated by the CENP-C-mediated targeting of the Mis18 complex (Mis18a, Mis18b, Mis18BP1) to the centromeres at mitotic exit. Subsequently, the Mis18 complex recruits the CENP-A assembly factor, HJURP, to deposit new CENP-A at the centromeres in early G1. HJURP interacts mainly with the Mis18ab C-terminal domains which are essential but not sufficient for HJURP binding. The Mis18 complex is targeted to the centromeres by direct interaction between Mis18BP1 and Mis18b with the C-terminal region of CENP-C to establish a robust centromeric association of the Mis18 complex. Furthermore, CDK and PLK1-mediated negative and positive regulation, respectively, restrict CENP-A deposition to early G1 in humans. CDK phosphorylation prevents the Mis18 complex assembly and centromeric targeting, while PLK1 directly binds and phosphorylates the Mis18 complex that is important for the centromeric association of the Mis18 complex and CENP-A deposition in early G1. Until today, several important aspects of the CENP-A maintenance pathway were discovered, however, mechanistic details of how the CENP-A deposition machinery is targeted to the centromeres are not fully understood. By using biochemical and mammalian cell-based techniques, this study demonstrates the molecular basis for HJURP/Mis18ab interaction and the implications for CENP-A deposition. Here, we demonstrate that Mis18ab MeDiY domains also contribute to HJURP binding and this implicates CENP-A deposition in vivo. Moreover, phosphorylation of the N-terminal region of Mis18a, potentially by PLK1, positively modulates HJURP/Mis18 complex interaction. Importantly, this study identified new interacting residues between HJURP and Mis18ab MeDiY and C-terminal domains. Finally, biochemical characterisation of CENP-C/Mis18b interaction in vitro showed a robust 2:1 complex formation. Mapping the minimum interaction region of the complex revealed a novel role for the highly conserved CENP-C motif, previously implicated in CENP-A binding, in mediating Mis18b interaction. Collectively, this study provides further insights into novel molecular interactions and regulatory mechanisms of the CENP-A deposition machinery that is essential for centromere maintenance.

description: Quando si parla di amicizia nel mondo ebraico è doveroso fare riferimento ad alcune riflessioni di antropologia filosofica che possiamo trarre dalla Torah prima e dalgi scritti filosofici di Filone di Alessandria dopo. Si tratta, nella sostanza, di una serie di considerazioni il cui fine è quello di delineare in modo chiaro il concetto di antropologia, da una prospettiva giudaica. Questo concetto attraverserà in diverso modo i secoli, si scontrerà a vario titolo con i precetti delle religioni vicine e con le dottrine filosofiche dei gentili, sino a trovare un punto di sintesi e di accorso solo più tarsi, condizionando perfino parte della speculazione filosofica contemporanea.

description: We introduce collision free layerings as a powerful way to structure radio networks. These layerings can replace hard-to-compute BFS-trees in many contexts while having an efficient randomized distributed construction. We demonstrate their versatility by using them to provide near optimal distributed algorithms for several multi-message communication primitives. Designing efficient communication primitives for radio networks has a rich history that began 25 years ago when Bar-Yehuda et al. introduced fast randomized algorithms for broadcasting and for constructing BFS-trees. Their BFS-tree construction time was $O(D \log^2 n)$ rounds, where $D$ is the network diameter and $n$ is the number of nodes. Since then, the complexity of a broadcast has been resolved to be $T_{BC} = Θ(D \log \frac{n}{D} + \log^2 n)$ rounds. On the other hand, BFS-trees have been used as a crucial building block for many communication primitives and their construction time remained a bottleneck for these primitives. We introduce collision free layerings that can be used in place of BFS-trees and we give a randomized construction of these layerings that runs in nearly broadcast time, that is, w.h.p. in $T_{Lay} = O(D \log \frac{n}{D} + \log^{2+ε} n)$ rounds for any constant $ε>0$. We then use these layerings to obtain: (1) A randomized algorithm for gathering $k$ messages running w.h.p. in $O(T_{Lay} + k)$ rounds. (2) A randomized $k$-message broadcast algorithm running w.h.p. in $O(T_{Lay} + k \log n)$ rounds. These algorithms are optimal up to the small difference in the additive poly-logarithmic term between $T_{BC}$ and $T_{Lay}$. Moreover, they imply the first optimal $O(n \log n)$ round randomized gossip algorithm.
Biot-Savart helicity versus physical helicity: A topological description of ideal flows

description: For an isentropic (thus compressible) flow, fluid trajectories are considered as orbits of a family of one parameter, smooth, orientation preserving and nonsingular diffeomorphisms on a compact and smooth-boundary domain in the Euclidian 3-space which necessarily preserve a finite measure, later interpreted as the fluid mass. Under such diffeomorphisms the Biot-Savart helicity of the pushforward of a divergence-free and tangent to the boundary vector field is proved to be conserved and since these circumstances present an isentropic flow, the conservation of the "Biot-Savart helicity" is established for such flows. On the other hand, the well known helicity conservation in ideal flows which here we call it "physical helicity" is found to be an independent constant with respect to the Biot-Savart helicity. The difference between these two helicities reflects some topological features of the domain as well as the velocity and vorticity fields which is discussed and is shown for simply connected domains the two helicities coincide. The energy variation of the vorticity field is shown to be formally the same as for the incompressible flow obtained before. For fluid domains consisting of several disjoint solid tori, at each time, the harmonic knot subspace of smooth vector fields on the fluid domain is found to have two independent base sets with a special type of orthogonality between these two bases by which a topological description of the vortex and velocity fields depending on the helicity difference is achieved since this difference is shown to depend only on the harmonic knot parts of velocity, vorticity and its Biot-Savart vector field. For an ideal MHD flow three independent constant helicities are reviewed while the helicity of magnetic potential is generalized for non-simply connected domains by inserting a special harmonic knot field in the dynamics of the magnetic potential.
The definition of tokens in relation to words and annotation tasks

description: Tokens are the basic units of annotations. When working with corpora of non-standardized texts, tokenization is often problematic, as the usage of whitespace can vary. We show examples of how decisions in the tokenization process can influence an annotation and argue that the principles underlying the tokenization should be grounded in theoretical concepts selected on the basis of the annotation task. We present a corpus of Early New High German texts in which the annotation layers reference two different concepts of words: syntactic words and graphematic words. Consequently, we use two kinds of tokens: graphic tokens and syntactic tokens.

description: Atomic and molecular samples reduced to temperatures below 1 microkelvin, yet still in the gas phase, afford unprecedented energy resolution in probing and manipulating how their constituent particles interact with one another. For simple atoms, such as alkalis, scattering resonances are extremely well-characterized. However, ultracold physics is now poised to enter a new regime, where far more complex species can be cooled and studied, including magnetic lanthanide atoms and even molecules. For molecules, it has been speculated that a dense forest of resonances in ultracold collision cross sections will likely express essentially random fluctuations, much as the observed energy spectra of nuclear scattering do. According to the Bohigas-Giannoni-Schmit conjecture, these fluctuations would imply chaotic dynamics of the underlying classical motion driving the collision. This would provide a paradigm shift in ultracold atomic and molecular physics, necessitating new ways of looking at the fundamental interactions of atoms in this regime, as well as perhaps new chaos-driven states of ultracold matter. In this report we provide the first experimental demonstration that random spectra are indeed found at ultralow temperatures. In the experiment, an ultracold gas of erbium atoms is shown to exhibit many Fano-Feshbach resonances, for bosons on the order of 3 per gauss. Analysis of their statistics verifies that their distribution of nearest-neighbor spacings is what one would expect from random matrix theory. The density and statistics of these resonances are explained by fully-quantum mechanical scattering calculations that locate their origin in the anisotropy of the atoms' potential energy surface. Our results therefore reveal for the first time chaotic behavior in the native interaction between ultracold atoms.

description: We present a series of systematic abundance measurements for 89 hydrogen atmosphere (DA-type) white dwarfs with temperatures spanning 16000-77000K drawn from the FUSE spectral archive. This is the largest study to date of white dwarfs where radiative forces are significant, exceeding our earlier work, based mainly on IUE and HST data, by a factor three. Using heavy element blanketed non-LTE stellar atmosphere calculations, we have addressed the heavy element abundance patterns making completely objective measurements of abundance values and their error ranges using a \c{hi}2 fitting technique. We are able to establish the broad range of abundances seen in a given temperature range and establish the incidence of stars which appear, in the optical, to be atmospherically devoid of any material other than H. We compare the observed abundances to predictions of radiative levitation calculations, revealing little agreement. We propose that the supply of heavy elements is accreted from external sources rather than being intrinsic to the star. These elements are then retained in the white dwarf atmospheres by radiative levitation, a model that can explain both the diversity of measured abundances for stars of similar temperature and gravity, including cases with apparently pure H envelopes, and the presence of photospheric metals at temperatures where radiative levitation is no longer effective.

description: We present the results of a survey aimed at discovering and studying transiting planets with orbital periods shorter than one day (ultra--short-period, or USP, planets), using data from the {\em Kepler} spacecraft. We computed Fourier transforms of the photometric time series for all 200,000 target stars, and detected transit signals based on the presence of regularly spaced sharp peaks in the Fourier spectrum. We present a list of 106 USP candidates, of which 18 have not previously been described in the literature. In addition, among the objects we studied, there are 26 USP candidates that had been previously reported in the literature which do not pass our various tests. All 106 of our candidates have passed several standard tests to rule out false positives due to eclipsing stellar systems. A low false positive rate is also implied by the relatively high fraction of candidates for which more than one transiting planet signal was detected. By assuming these multi-transit candidates represent coplanar multi-planet systems, we are able to infer that the USP planets are typically accompanied by other planets with periods in the range 1-50 days, in contrast with hot Jupiters which very rarely have companions in that same period range. Another clear pattern is that almost all USP planets are smaller than 2 $R_\oplus$, possibly because gas giants in very tight orbits would lose their atmospheres by photoevaporation when subject to extremely strong stellar irradiation. Based on our survey statistics, USP planets exist around approximately $(0.51\pm 0.07)\%$ of G-dwarf stars, and $(0.83\pm 0.18)\%$ of K-dwarf stars.

description: Infrared reflectivity spectra of cubic SrMnO$_{3}$ ceramics reveal 18 % stiffening of the lowest-frequency phonon below the antiferromagnetic phase transition occurring at T$_{N}$ = 233 K. Such a large temperature change of the polar phonon frequency is extraordinary and we attribute it to an exceptionally strong spin-phonon coupling in this material. This is consistent with our prediction from first principles calculations. Moreover, polar phonons become Raman active below T$_{N}$, although their activation is forbidden by symmetry in $Pm\bar{3}m$ space group. This gives evidence that the cubic $Pm\bar{3}m$ symmetry is locally broken below T$_{N}$ due to a strong magnetoelectric coupling. Multiphonon and multimagnon scattering is also observed in Raman spectra. Microwave and THz permittivity is strongly influenced by hopping electronic conductivity, which is caused by small non-stoichiometry of the sample. Thermoelectric measurements show room-temperature concentration of free carriers $n_{e}=$3.6 10$^{20}$ cm$^{-3}$ and the sample composition Sr$^{2+}$Mn$_{0.98}^{4+}$Mn$_{0.02}^{3+}$O$_{2.99}^{2-}$. The conductivity exhibits very unusual temperature behavior: THz conductivity increases on cooling, while the static conductivity markedly decreases on cooling. We attribute this to different conductivity of the ceramic grains and grain boundaries.

Hierzu wird ein systematischer Vergleich der relevanten Faktoren der Frauenerwerbstätigkeit im Vergleich zum Bundesgebiet und den 16 Bundesländern durchgeführt. Datenbasis ist der Mikrozensus. Im Rahmen von deskriptiven und multivariaten Analysen wird der Einfluss von Bildungsniveau, Lebensphase, Migrationshintergrund, Lebensform und Mutterschaft untersucht. Zusätzlich werden Kinderbetreuungsangebote (Kitas/Schulen) und die Branchenstruktur der Wirtschaft vergleichend dargestellt, da diese Faktoren ebenfalls Einfluss auf die Erwerbsbeteiligung von Müttern haben können. In der Mehrzahl der Fälle sind in Paargemeinschaften mittlerweile beide Partner erwerbstätig. Die klassische Konstellation eines alleinverdienenden Partners findet man nur noch in etwa einem Fünftel der Fälle. Wenn Kinder im Haushalt leben, bestimmt vor allem das Alter des jüngsten Kindes die Erwerbsneigung und -beteiligung der Mütter. Mit dem Alter des jüngsten Kindes nimmt die Erwerbsneigung und - beteiligung relativ unabhängig von der Lebensform zu. In NRW wirkt sich außerdem der überdurchschnittlich hohe Anteil an Paargemeinschaften in SGB-II Bezug negativ auf die Erwerbsquote aus.

description: In many radar scenarios, the radar target or the medium is assumed to possess randomly varying parts. The properties of a target are described by a random process known as the spreading function. Its second order statistics under the WSSUS assumption are given by the scattering function. Recent developments in operator sampling theory suggest novel channel sounding procedures that allow for the determination of the spreading function given complete statistical knowledge of the operator echo from a single sounding by a weighted pulse train. We construct and analyze a novel estimator for the scattering function based on these findings. Our results apply whenever the scattering function is supported on a compact subset of the time-frequency plane. We do not make any restrictions either on the geometry of this support set, or on its area. Our estimator can be seen as a generalization of an averaged periodogram estimator for the case of a non-rectangular geometry of the support set of the scattering function.

description: External spiral galaxies seen edge-on exhibit X-shape magnetic fields in their halos. Whether the halo of our own Galaxy also hosts an X-shape magnetic field is still an open question. We would like to provide the necessary analytical tools to test the hypothesis of an X-shape magnetic field in the Galactic halo. We propose a general method to derive analytical models of divergence-free magnetic fields whose field lines are assigned a specific shape. We then utilize our method to obtain four particular models of X-shape magnetic fields in galactic halos. In passing, we also derive two particular models of predominantly horizontal magnetic fields in galactic disks. All our field models have spiraling field lines with spatially varying pitch angle. Our four halo field models do indeed lead to X patterns in synthetic synchrotron polarization maps. Their precise topologies can all be explained by the action of a wind blowing outward from the galactic disk or from the galactic center. In practice, our field models may be used for fitting purposes or as inputs to various theoretical problems.

description: The use of online server applications has increased in recent years. To achieve the benefits of these technologies, cloud computing, with its ability to use virtual machine technologies to overcome limitations and guarantee security and quality of service to its end user customer, is being used as a platform to run online server applications. This however brings about a number of security issues aimed specifically at virtual machine technologies. A number of security solutions like virtual machine introspection, intrusion detection and many more, have been proposed and implemented, but the question to combat security issues in near or even real time still remains. To help answer the above question or even move a step further from the existing solutions, which still use data mining techniques to combat the security issues of virtualisation, we propose the novel use of predictive analytics for risk analysis and management of security threats in virtualised information systems as well as design and implement a novel predictive analytics framework used to design build and implement the same predictive analytics model In this project, we adopt the use of predictive analytics and demonstrate how it can be used for managing risks and security of virtualised environments. An experimental testbed for the simulation of attacks and data collection is set-up. Exploratory data analytics process is carried out to prepare the data for predictive modelling. A linear regression predictive model is built using the results from the exploratory data analytics using linear regression algorithm. The model is then validated and tested for predictive accuracy using Naïve Bayes and logistic algorithms respectively. Time series algorithms are then used to build a time series predictive model that will predict attacks (DoS attacks in this case) in real time using new data. Designing and implementing the proposed predictive analytics model, which is aimed at monitoring, analysing and mitigating security threats in real time successfully demonstrates the use of predictive analytics modelling as a security management tool for virtualised information systems as a novel contribution to virtualisation security.

The pure state concepts are reviewed using a concrete spin-1 model. For the mixed state setup we demonstrate our findings numerically using matrix product state algorithms. Starting from the ground state and applying various types of noise sources we find a transient regime where the system is driven out of equilibrium while retaining its topological properties.

description: The study focuses on examining the sustainability challenges associated with CubeSats\' rapid prototyping and in-orbit demonstration (IOD). The topic is highly relevant nowadays, especially for university student associations working on CubeSat missions. Environmental, economic, and societal factors are all part of these sustainability concerns. Despite the lack of existing research, the rising demand for Cubes ats necessitates addressing these issues. CubeSats are selected for investigation due to their popularity, compactness, and cost-effectiveness. The goal of this research is to establish criteria for sustainable prototyping and IOD practices, crucial for technological progress but requiring greater attention to sustainability. The authors propose an approach, highlighting the significance of well-planned IODs and improved end-of-life strategies for CubeSats to foster sustainability in the industry. The research includes a case study about the EPFL Spacecraft Team, which is an example of a student association working on IODs for their CubeSat. 1.

description: The current research explored the correlations between working memory capacity and the development of reading in a sample of Moroccan primary school pupils. It appeared from previous studies that working memory capacity mediated reading performance in alphabetic and morphemic languages; however, few studies have addressed the correlations between reading and working memory in Arabic language. It has also been shown that working memory determines variability in reading performance. A sample of 96 children ranging in age from 6 to 12 years, participated in this study. They were subjected to tests that included word recognition, reading comprehension, and working memory. It was found from the statistical analysis of the data that the effect of working memory capacity on reading performance does not appear clearly in the first two years of primary school. However, in the later stages of reading, there was a significant correlation between working memory capacity and reading performance. Additionally, it was uncovered that working memory assessments can predict reading performance for primary school children. The study concluded that measures of working memory capacity can help to the early diagnostic of children at risk of reading difficulties.

A local, electrically excited source of SPPs using a scanning tunnelling microscope (STM) produces an outgoing circular plasmon wave on a thick (200 nm) gold film on glass containing holes of 250, 500 and 1000 nm diameter. Fourier plane images of the photons from hole-scattered plasmons show that the larger the hole diameter, the more directional the scattered radiation. These results are confirmed by a model where the hole is considered as a distribution of horizontal dipoles whose relative amplitudes, directions, and phases depend linearly on the local SPP electric field. An SPP-Young's experiment is also performed, where the STM-excited SPP-wave is incident on a pair of 1 $μ$m diameter holes in the thick gold film. The visibility of the resulting fringes in the Fourier plane is analyzed to show that the polarization of the electric field is maintained when SPPs scatter into photons. From this SPP-Young's experiment, an upper bound of $\approx$ 200 nm for the radius of this STM-excited source of surface plasmon polaritons is determined.

description: Poor teamwork skills in healthcare have been found to be a contributing cause of negative incidents in patient care, whilst effective teamwork has been linked to more positive patient outcomes. This programme of work aimed to evaluate how to better prepare undergraduate pharmacy students for their future roles in interprofessional teams. The programme of work consisted of four qualitative phases. Phases 1 and 2 involved focus group to explore characteristics of an effective interprofessional team from the perspective of 14 patients and informal caregivers, and 19 pharmacy students. Student views on opportunities to develop teamwork characteristics within their Masters of Pharmacy programme were also explored. Phase 3 consisted of semi-structured interviews with ten educators involved in the design and/or delivery of pharmacy curricula, to establish their perceptions on key teamwork characteristics and how undergraduates were prepared for working in interprofessional teams. The final phase triangulated the findings from phases 1-3 to provide a comprehensive account of key teamwork characteristics and to inform recommendations for curriculum development for pharmacy students. Analyses identified several key teamwork characteristics including communication, understanding their own role and the role of others, leadership, hierarchies and compassion. Communication, role understanding mutual trust and respect and the need for a team leader were considered to be key by all participants. The need for improvements in communication was highlighted by patients. Pharmacy curriculums should clearly identify how teamwork is taught to pharmacy students. Teamwork-focussed learning outcomes and objectives should be explicit for associated teaching, learning and assessments. Interprofessional education, experiential and simulation-based learning were considered beneficial and suitable mechanisms to be better prepare students for future practice in interprofessional teams. Supplemental clinical funding is required to facilitate experiential learning opportunities that would align pharmacy education with other healthcare education degrees.

description: The aim of this paper is to present the simultaneous development of three interrelated linguistic resources for Polish: a valence dictionary, a formal grammar, and a syntactic corpus. This parallel development creates a strong synergistic effect: the valence dictionary is constantly verified by its use in the formal grammar, and both are verified in the process of constructing the structure bank.

description: Let $(W,S)$ be a Coxeter system, $S$ finite, and let $G_{W}$ be the associated Artin group. One has configuration spaces $Y,\ Y_{W},$ where $G_{W}=π_1(Y_{W}),$ and a natural $W$-covering $f_{W}:\ Y\to Y_{W}.$ The Schwarz genus $g(f_{W})$ is a natural topological invariant to consider. In this paper we generalize this result by computing the Schwarz genus for a class of Artin groups, which includes the affine-type Artin groups. Let $K=K(W,S)$ be the simplicial scheme of all subsets $J\subset S$ such that the parabolic group $ W_J $ is finite. We introduce the class of groups for which $dim(K)$ equals the homological dimension of $K,$ and we show that $g(f_{W})$ is always the maximum possible for such class of groups. For affine Artin groups, such maximum reduces to the rank of the group. In general, it is given by $dim(X_{W})+1,$ where $ X_{ W}\subset Y_{ W}$ is a well-known $CW$-complex which has the same homotopy type as $ Y_{ W}.$

description: A structural understanding of whole cells in three dimensions at high spatial resolution remains a significant challenge and, in the case of X-rays, has been limited by radiation damage. By alleviating this limitation, cryogenic coherent diffraction imaging (cryo-CDI) could bridge the important resolution gap between optical and electron microscopy in bio-imaging. Here, we report for the first time 3D cryo-CDI of a whole, frozen-hydrated cell - in this case a Neospora caninum tachyzoite - using 8 keV X-rays. Our 3D reconstruction reveals the surface and internal morphology of the cell, including its complex, polarized sub-cellular architecture with a 3D resolution of ~75-100 nm, which is presently limited by the coherent X-ray flux and detector size. Given the imminent improvement in the coherent X-ray flux at the facilities worldwide, our work forecasts the possibility of routine 3D imaging of frozen-hydrated cells with spatial resolutions in the tens of nanometres.

description: Radial velocities and metallicities have been measured for 82 RR Lyrae identified by the QUEST survey in the direction of the Virgo constellation. Distributed over 90 sq. deg. of the sky, they lie from 4 to 23 kpc from the Sun. Using an algorithm for finding groups in phase space and modeling the smooth halo component in the region, we identified the 5 most significant RRLS groups. We have examined the SEKBO and the Catalina catalog of RRLS (Prior et al. 2009, and Drake et al. 2013), as well as the bright QUEST RRLS sample (Vivas et al. in prep.), the catalogs of Blue Horizontal Branch stars compiled by Sirko et al (2004) and Brown et al (2008, 2010) and the catalog of Red Giant stars from the Spaghetti survey, for stars that may be related to the QUEST RRLS groups. The most significant group of RRLS is the Virgo Stellar Stream (VSS, Duffau et al 2006), group A, which is composed of at least 10 RRLS and 3 BHB stars. It has a mean distance of 19.6 kpc and a mean radial velocity Vgsr = 128 km/s, as estimated from its RRLS members. With the revised velocities reported here, there is no longer an offset in velocity between the RRLS in the VSS and the prominent peak in the velocities of main-sequence turnoff stars reported by Newberg et al (2007) in the same direction and at a similar distance (S297+63-20.5). The location in phase space of two other groups (F,H) suggests a possible connection with the VSS, which cannot be discarded at this point, although the turnoff colors of the VSS and group H, as identified from Newberg et al. (2007), suggest they might be composed of different populations. Two more groups (B,D), are found at mean distances of 19 and 5.7 kpc, and mean radial velocities of -94 and 32 km/s. None of our groups seems to relate to Sgr streams. The excess of stars observed in Virgo appears to be composed of several halo substructures along the same line of sight.

description: The temperature and magnetic field dependence of lattice and carrier excitations in MnSi is studied in detail using inelastic light scattering. The pure symmetry components of the electronic response are derived from the polarization dependent spectra. The $E$ and $T_2$ responses agree by and large with longitudinal and optical transport data. However, an anomaly is observed right above the magnetic ordering temperature $T_{\rm C}=29\,{\rm K}$ that is associated with the fluctuations that drive the transition into the helimagnetic phase first order. The $T_1$ spectra, reflecting mostly chiral spin excitations, have a temperature dependence similar to that of the $E$ and $T_2$ symmetries. The response in the fully symmetric $A$ representation has a considerably weaker temperature dependence than that in the other symmetries. All nine Raman active phonon lines can be resolved at low temperature. The positions and line widths of the strongest four lines in $E$ and $T_2$ symmetry are analyzed in the temperature range $4

Revisiting the Saffman-Taylor experiment: imbibition patterns and liquid-entrainment transitions

description: We revisit the Saffman-Taylor experiment focusing on the forced-imbibition regime where the displacing fluid wets the confining walls. We demonstrate a new class of invasion patterns that do not display the canonical fingering shapes. We evidence that these unanticipated patterns stem from the entrainement of thin liquid films from the moving meniscus. We then theoretically explain how the interplay between the fluid flow at the contact line and the interface deformations results in the destabilization of liquid interfaces moving past solid surfaces. In addition, this minimal model conveys a unified framework which consistently accounts for all the liquid-entrainment scenarios that have been hitherto reported.
