description: We investigate the idea of detecting pure neutrino-hydrogen interactions in a multinuclear target using the transverse kinematic imbalance technique [Lu et al., Phys. Rev. D 92, 051302 (2015)] in a high-pressure time projection chamber (HPTPC). With full solid-angle acceptance, MeV-level proton tracking threshold, state-of-the-art tracking resolution, and an O(100 m^3) gas volume at 10 bar, an HPTPC could provide an opportunity to realize this technique. We propose the use of hydrogen-rich gases in the TPC to achieve high detection purity with large hydrogen mass. With the projected neutrino beam exposure at the DUNE experiment, neutrino-hydrogen events of the order of 10^4 per year with purity above 90% could be achieved with such an HPTPC using methane gas. In this paper, we present a systematic study of the event rate and purity for a variety of argon-alkane mixtures, and examine these gas candidates for the TPC tracking-related properties.

description: In a fully 3-D system such as a stellarator, the toroidal mode number $n$ ceases to be a good quantum number--all $n$s within a given mode family being coupled. It is found that the discrete spectrum of unstable ideal MHD (magnetohydrodynamic) instabilities ceases to exist unless MHD is modified (regularized) by introducing a short-perpendicular-wavelength cutoff. Attempts to use ray tracing to estimate the regularized MHD spectrum fail due to the occurrence of chaotic ray trajectories. In quantum chaos theory, strong chaos in the semiclassical limit leads to eigenvalue statistics the same as those of a suitable ensemble of random matrices. For instance, the probability distribution function for the separation between neighboring eigenvalues is as derived from random matrix theory and goes to zero at zero separation. This contrasts with the Poissonian distribution found in separable systems, showing that a signature of quantum chaos is level repulsion. In order to determine whether eigenvalues of the regularized MHD problem obey the same statistics as those of the Schrödinger equation in both the separable 1-D case and the chaotic 3-D cases, we have assembled data sets of ideal MHD eigenvalues for a Suydam-unstable cylindrical (1-D) equilibrium using \emph{Mathematica} and a Mercier-unstable (3-D) equilibrium using the CAS3D code. In the 1-D case, we find that the unregularized Suydam-approximation spectrum has an anomalous peak at zero eigenvalue separation. On the other hand, regularization by restricting the domain of $\kvec_{\perp}$ recovers the expected Poissonian distribution. In the 3-D case we find strong evidence of level repulsion within mode families, but mixing mode families produces Poissonian statistics.

description: Die Sozialarbeitenden können dann handeln, wenn soziale Probleme sichtbar sind. Dabei stellt sich die Frage, wie queer_feministische Soziale Arbeit konzeptualisiert werden kann, dass sie die Macht der Heteronormativität entlarvt und neue Imaginationen der Zugehörigkeit möglich/denkbar macht und dass ihre eigenen Verstrickungen in die Normalisierungs- und Ausschlussprozesse zum Vorschein kommen. In meinem Beitrag skizziere ich einen theoretisch begründeten Ansatz queer_feministischer Sozialer Arbeit, die ich als Arbeit an der Sichtbarkeitsfalle konzeptualisiere. Diese Sichtbarkeitsfalle umschreibe ich mit der Interdependenz von drei Momenten: die Provinzialisierung der Heterosexualität als Norm, die Adressierung einer bestimmten sozialen Verletzlichkeit und die Verortung des Problems in den Subjektivierungsweisen. Der Fokus auf die Sichtbarkeit veranschaulicht den Zusammenhang zwischen gesellschaftlicher/rechtlich-politischer Ordnung von Geschlecht und Sexualität, Subjektivierungsweisen der Adressat*innen der Sozialen Arbeit sowie dem professionellen sozialarbeiterischen Handeln.

description: We studied the production of protons to the backward direction in (p,2p) reactions on 6Li and 12C, accompanied by a proton emitted into the forward hemisphere. The momenta of the final two protons were measured in a wide range with the two-arm time-of-flight spectrometer. For each event we reconstructed the mass of the intermediate off-shell particles. We have discovered a strong narrow dip in the mass spectra of intermediate mesons at the mass of the real pion.

description: Any local gauge theory can be represented as an AKSZ sigma model (upon parameterization if necessary). However, for non-topological models in dimension higher than 1 the target space is necessarily infinite-dimensional. The interesting alternative known for some time is to allow for degenerate presymplectic structure in the target space. This leads to a very concise AKSZ-like representation for frame-like Lagrangians of gauge systems. In this work we concentrate on Einstein gravity and show that not only the Lagrangian but also the full-scale Batalin--Vilkovisky formulation is naturally encoded in the presymplectic AKSZ formulation, giving an elegant supergeometrical construction of BV for Cartan-Weyl action. The same applies to the main structures of the respective Hamiltonian BFV formulation.

We investigate the flux flow and the pinning of the vortex sheet structure. We find domain wall that traps half flux-quantum vortices and moves with the flux flow. In the pinning case, we observe an emitting process of a conventional vortex from the vortex sheet by combining a pair of half flux-quantum vortices.

description: Fully non-linear equations of motion for dissipative general relativistic multi-fluids can be obtained from an action principle involving the explicit use of lower dimensional matter spaces. More traditional strategies for incorporating dissipation-like the famous Mueller-Israel-Stewart model-are based on expansions away from equilibrium defined, in part, by the laws of thermodynamics. The goal here is to build a formalism to facilitate comparison of the action-based results with those based on the traditional approach. The first step of the process is to use the action-based approach itself to construct self-consistent notions of equilibrium. Next, first-order deviations are developed directly on the matter spaces, which motivates the latter as the natural arena for the underlying thermodynamics. Finally, we identify the dissipation terms of the action-based model with first-order "thermodynamical" fluxes, on which the traditional models are built. The description is developed in a general setting so that the formalism can be used to describe multi-fluid systems, for which causal and stable models are not yet available. As an illustration of the approach, a simple application of a single viscous fluid is considered and, even though the expansion is halted at first order, we sketch how a causal response can be implemented through Cattaneo-type equations.

title: The Social Significance of Curse Tablets in the North-Western Provinces of the Roman Empire
Creators: name: Mckie, Stuart
Publisher: name: The Open University
Year: 2017

description: The use of curse tablets was an important method for ancient people to cope with life, as shown by the increasing number of tablets found across the Graeco-Roman world. They could address a variety of problems and crises, including sexual relationships, crime, legal trials and economic competition. The study of these enigmatic objects by archaeologists and ancient historians has been dominated by the evidence from the Graeco-Egyptian traditions of magic, as well as their value for linguistics and philology as evidence for vulgar and vernacular language. In contrast, this study focuses on the importance of cursing as a contextually embedded ritual within the everyday lives of people living in the Roman north-western provinces. To achieve this aim, the present study had examined curse tablets through the lens of a number of theoretical models and discussions that have been developed by other scholars, both within archaeology and in other related fields. Phenomenological thinking has played a particularly significant role, as the reconfiguring of humans as embedded beings-in-the-world has allowed a much greater understanding of cursing as a creative ritual process. This thesis also looks at similar ritual practices in modern social contexts that have been observed by anthropologists and ethnographers, and uses them to ask new questions of the ancient evidence, particularly with regard to the motives and motivations behind the curses. By thinking in these new ways, this study has moved the scholarly discussions on curse tablets beyond the preoccupations about categorization. I have also brought curse tablets into contact with ongoing scholarly discussions about identity and agency in the Roman provinces, and have shown that these objects have great potential for informing these debates, despite their relative neglect by archaeologists and historians.

description: It is shown that a good estimate of the fidelity of an experimentally realized quantum process can be obtained by measuring the outputs for only two complementary sets of input states. The number of measurements required to test a quantum network operation is therefore only twice as high as the number of measurements required to test a corresponding classical system.

The D=4 world volume Nambu-Goldstone boson of broken translation invariance and the two D=4 world volume Weyl spinor Goldstinos of the completely broken supersymmetry describe the excitations of the brane into the broken space and superspace directions. The resulting action is an invariant synthesis of the Akulov-Volkov and Nambu-Goto actions. The D=4 antisymmetric tensor gauge theory action dual to the p=3 brane action is determined.

description: The periodically driven O(N) model is studied near the critical line separating a disordered paramagnetic phase from a period doubled phase, the latter being an example of a Floquet time crystal. The time evolution of one-point and two-point correlation functions are obtained within the Gaussian approximation and perturbatively in the drive amplitude. The correlations are found to show not only period doubling, but also power-law decays at large spatial distances. These features are compared with the undriven O(N) model, in the vicinity of the paramagnetic-ferromagnetic critical point. The algebraic decays in space are found to be qualitatively different in the driven and the undriven cases. In particular, the spatio-temporal order of the Floquet time crystal leads to position-momentum and momentum-momentum correlation functions which are more long-ranged in the driven than in the undriven model. The light-cone dynamics associated with the correlation functions is also qualitatively different as the critical line of the Floquet time crystal shows a light-cone with two distinct velocities, with the ratio of these two velocities scaling as the square-root of the dimensionless drive amplitude. The Floquet unitary, which describes the time evolution due to a complete cycle of the drive, is constructed for modes with small momenta compared to the drive frequency, but having a generic relationship with the square-root of the drive amplitude. At intermediate momenta, which are large compared to the square-root of the drive amplitude, the Floquet unitary is found to simply rotate the modes. On the other hand, at momenta which are small compared to the square-root of the drive amplitude, the Floquet unitary is found to primarily squeeze the modes, to an extent which increases upon increasing the wavelength of the modes, with a power-law dependence on it.

description: This paper investigates the adjustment mechanism between farm input prices, farm output prices, and food retail prices in Canada. Johansen's maximum likelihood approach is used in addition to the Engle-Granger approach to test for cointegration. Contrary to the common assumption that farm output prices are more flexible than farm input prices, it is found that farm output prices though cointegrated are weakly exogenous in the sense that they do not respond in a systematic manner to disequilibrium in farm input prices and food retail prices. Evidence was found to support "Cost Pushl! and "Demand Pull" theories but since food retail prices carry a heavier weight in the cointegration relations, it can be concluded that shocks manifesting themselves (first) at the retail level do not persist as long.

description: A common practice in Australian vineyards is to manage under-vine weeds with approved herbicides applied one or more times each year. A current project is testing the potentials in a range of pasture species and cereal straw as under-vine mulches compared with herbicides for weed control. Grass and legume pasture species in under-vine trials in 2015-16 have shown promising results at some sites, with grape yields in some cases exceeding those of the herbicide control plots. Weeds compete with vines for water and nutrients and may provide a ‘green bridge’ between seasons, hosting pests and pathogens below the vines. Among the problems with repeated use of herbicides is the evolution of resistant populations of weeds, and their spread within the vineyard and to neighbouring properties and public lands. This study subtracts the costs of typical herbicide regimes and those of alternative mulches and other operational vineyard costs from the values of their respective grape yields, as baseline prices and yields vary over time, to define the distribution of Gross Margins for each treatment. Further subtracting the manager’s living costs, annual overheads, interest and taxes for random 10-year samples of simulated yields and prices allows estimation of long-term distributions of decadal cash balances for each under-vine treatment. Showing the probabilities of vineyard financial viability, these are private financial risk profiles for each treatment, differing by location. Juxtaposing these with the value of reduced risk of herbicide-resistant weed seed spreading beyond the vineyard permits analysis in a Public-Private Benefit Framework.

The matching relativistic amplitudes may be determined either from short-distance perturbation theory or from finite-volume step-scaling recursion. Tree-level matching and non-perturbative off-shell amplitudes are presented.

description: Many-body localization provides a mechanism to avoid thermalization in isolated interacting quantum systems. The breakdown of thermalization may be complete, when all eigenstates in the many-body spectrum become localized, or partial, when the so-called many-body mobility edge separates localized and delocalized parts of the spectrum. Previously, De Roeck \textit{et al.}[arXiv:1506.01505] suggested a possible instability of the many-body mobility edge in energy density. The local ergodic regions -- so called "bubbles" -- resonantly spread throughout the system, leading to delocalization. In order to study such instability mechanism, in this work we design a model featuring many-body mobility edge in \emph{particle density}: the states at small particle density are localized, while increasing the density of particles leads to delocalization. Using numerical simulations with matrix product states we demonstrate the stability of MBL with respect to small bubbles in large dilute systems for experimentally relevant timescales. In addition, we demonstrate that processes where the bubble spreads are favored over processes that lead to resonant tunneling, suggesting a possible mechanism behind the observed stability of many-body mobility edge. We conclude by proposing experiments to probe particle density mobility edge in Bose-Hubbard model.

description: In this note, we give an introduction to the concept of maximal $L^p$-regularity as a method to solve nonlinear partial differential equations. We first define maximal regularity for autonomous and non-autonomous problems and describe the connection to Fourier multipliers and $\mathcal R$-boundedness. The abstract results are applied to a large class of parabolic systems in the whole space and to general parabolic boundary value problems. For this, both the construction of solution operators for boundary value problems and a characterization of trace spaces of Sobolev spaces are discussed. For the nonlinear equation, we obtain local in time well-posedness in appropriately chosen Sobolev spaces. This manuscript is based on known results and consists of an extended version of lecture notes on this topic.

title: Tracing The Patterns : Boys And Their Literacy In The Early Years
Creators: name: Hodgeon, Julia
Publisher: name: The Open University
Year: 2003

description: The purpose of this ethnographic study is to uncover relationships between the development of masculinities, the acquisition of early literacy and classroom processes. These processes include the early stages of the introduction of the National Literacy Strategy. The focus of the study is to examine literacy experiences in the early years classroom with reference to current anxieties about the progress and achievements of boys. The setting is a medium-sized primary school in the North of England. Data are drawn from participant and non-participant observation of adults and children, informal interviews and conversations with adults and the use of a questionnaire as the basis for informal interviews with children. Evidence is presented which suggests that boys in the class are already beginning to develop negative attitudes to literacy; possible factors to account for this are considered. These include administrative organisation, differential teacher expectations of boys and girls, the development of masculine subjectivities into resistance and boys' avoidance of literacy experiences through coping strategies. The impact of the introduction of the National Literacy Strategy on the gendered acquisition of early literacy is given detailed consideration. Findings indicate that all these factors do have considerable influence on differences in children's confidence in their approach to literacy attainment. The paper concludes that, with regard to future school policies, there is scope for greater co-operation between teachers in exploring the connections between gender, literacy attainment and classroom processes. It proposes that such explorations should be focused on both girls and boys. It explores ways in which such discussions might be begun. It proposes some ways in which practice might be modified. Suggestions for further classroom research are also made.

description: Let the reciprocal Newton 'constant' be an apparently non-dynamical Brans-Dicke scalar field damped oscillating towards its General Relativistic VEV. We show, without introducing additional matter fields or dust, that the corresponding cosmological evolution averagely resembles, in the Jordan frame, the familiar dark radiation -> dark matter -> dark energy domination sequence. The fingerprints of our theory are fine ripples, hopefully testable, in the FRW scale factor; they die away at the General Relativity limit. The possibility that the Brans-Dicke scalar also serves as the inflaton is favorably examined.

title: Use Of Action Research To Reduce The Theory-Practice Gap In A Nursing Course
Creators: name: Field, Dorothy
Publisher: name: The Open University
Year: 2003

description: This small scale action research study explored the causes of a theory practice gap in a specialist post registration nursing course, studied in one geographical area in England, and set out to discover how it may be reduced. Educational and nursing literature was studied to focus the aims of the study. Research questions are proposed and investigated using an action research methodology. The action research data is presented in three parts: interviews with the research participants, examination of documentary evidence and the main focus of the study, the action research cycles. Challenges with the chosen methodology were identified early in the study, and a solution was developed which will also serve to add to the evidential basis of the action research cycles which are presented in narrative forin. The study was written in the first person, and acknowledges the researcher's presence and influences within the data. Past and present students, their managers and mentors all contributed to the study, and have all checked the data for validity. The overall aim of the action research approach was to gather data from educational theorists, and those who participated in the course to adapt or change the nursing curriculum to facilitate the students' professional development as ophthalmic nurses. The research was not just about the results achieved in terms of course modifications; it was also about our development as a team of people working together to improve the ophthalmic nursing curriculum with the longer term objective of benefiting patients through the improvement of nursing practice. The research study was focussed on knowledge and the curriculum, and for the purposes of this nursing educational study the curriculum was perceived broadly, as those teaching and learning activities which take place in the university classroom, and more cogently, within the field of nursing practice. The study examined how current educational theories might be used to relate nursing theory and practice and educational policy at local and national level how might be related to a specialist nursing curriculum. It questioned what influence the Lecturer practitioner might have in relating theory to practice and how the role of the mentor might be used to coach higher levels of nursing practice. Key conclusions suggested that nursing lecturers need to continue to press for academic validation of nursing practice. The mentoring relationship is seen as the key in the reification of practice and theoretical knowledge. Well supervised clinical practice was seen as an essential part of learning nursing theory. The significant contributions that Mentors have to make to course management meetings in order that the academic study of nursing and the development of clinical practice are in a reciprocal relationship were demonstrated.

The effect of predator netting on clam recruitment in Baynes Sound, B.C. with a special focus on the response of the Manila clam (Venerupis philippinarum)
Creators: name: Munroe, Daphne Marie
Publisher: name: University of British Columbia
Year: 2010

description: Passive and active forces determine the patterns of settlement of invertebrate larvae. Research efforts into larval settlement have been dominated by attached and conspicuous species in hard substrate environments. Here, data on early recruitment patterns of a mobile bivalve species from a soft-sediment habitat is provided. In particular, how intertidal clam aquaculture netting influences the distribution of settling pediveliger larvae was investigated. Early recruitment patterns of Manila clam larvae (Venerupis philippinarum) were examined in relation to predator netting used in farming clams in British Columbia. A method for sampling recent settlers from intertidal sediments was developed, proven effective and employed to sample settled clams (<600 μm shell length) from four sites in Baynes Sound, on the eastern side of Vancouver Island, B.C. in 2003 and 2004. Paired netted and non-netted plots were compared for number of early recruits. Plots with the netting and high density of adult clams experienced lower levels of settlement. Settlement varied annually with 2003 experienceing [sic] an order of magnitude less recruitment than 2004. In addition, laboratory tests were run using flumes to examine the retention of competent clam larvae within flumes with netting on the bottom. No difference in the retention of clam larvae was observed due to netting or sediment treatments. Sediment properties (sediment grain size, organic carbon and inorganic carbon) were also compared between netted and non-netted plots. No difference was seen in the sediment properties measured except for slightly higher levels of organic carbon beneath nets; this was likely due to the higher number of adult clams beneath the nets. The netting buffers temperature at the sediment surface during tidal exposure by up to 3°C, the biological relevance of this remains untested. No increase in sedimentation was measured beneath netting; however, decreased bivalve settlement beneath netting was observed but only in the year when overall settlement was high. This decrease in recruitment was not supported by the flume trials; however these were run at one velocity. Trials at different velocities may produce different results. These field observations are an important contribution to understanding larval settlement of mobile species in a soft-sediment habitat.

description: Absorption spectroscopy is widely used in sensing and astronomy to understand molecular compositions on microscopic to cosmological scales. However, typical dispersive spectroscopic techniques require multichannel detection, fundamentally limiting the ability to detect extremely weak signals when compared to direct photometric methods. We report the realization of direct spectral molecular detection using a silicon nanophotonic waveguide resonator, obviating dispersive spectral acquisition. We use a thermally tunable silicon ring resonator with a transmission spectrum matched and cross-correlated to the quasi-periodic vibronic absorption lines of hydrogen cyanide. We show that the correlation peak amplitude is proportional to the number of overlapping ring resonances and gas lines, and that molecular specificity is obtained from the phase of the correlation signal in a single detection channel. Our results demonstrate on-chip correlation spectroscopy that is less restricted by the signal-to-noise penalty of other spectroscopic approaches, enabling the detection of faint spectral signatures.

description: Industrial harbours are a complex interface between environmental, economic and social systems. Trying to manage the social and economic needs of the community while maintaining the integrity of environmental ecosystems is complicated, as is the identification and evaluation of the various factors that underpin the drivers of economic, community and resource condition. An increasingly popular strategy to deal with the identification and evaluation challenges in complex human-environmental systems is to use a report card system which can be used as a summary assessment tool to monitor the health of aquatic ecosystems. The use of environmental report cards has become increasingly common but reporting has principally focused on environmental indicators. It is only very recently that attempts are being made to include social, cultural and economic indicators. There has been limited consensus in the selection of social and economic indicators applied in different aquatic report cards but as recreation is such an important activity, typically some measure of recreation benefit is included. However, there has been no commonality in the measures applied to assess its performance as an economic indicator. This paper is focused on the assessment of recreational benefits as an indicator of economic value in the report card for Gladstone Harbour in Queensland, Australia. It is the first aquatic health report card to include an assessment of the nonmarket value of recreation which makes it a more comprehensive indicator of economic value compared to estimates in other report cards based on measures of employment, participation or expenditure. There have now been three consecutive years of reporting (2014-2016) of the Gladstone Harbour report card, and the results indicate that the recreation index appears to be effectively monitoring changes over time.

description: We present a new link invariant which depends on a representation of the link group in SO(3). The computer calculations indicate that an abelian version of this invariant is expressed in terms of the Alexander polynomial of the link. On the other hand, if we use non abelian representation, we get the squared non abelian Reidemeister torsion (at least for some torus knots).

description: A possible Trans-Atlantic Trade and Investment Partnership (TTIP) agreement will further integrate agricultural markets between the United States and the European Union. The elimination of tariffs and cooperation on Sanitary and Phytosanitary measures will promote cross-Atlantic trade. We empirically estimate the impacts of tariffs and Maximum Residue Limits (MRLs) on trade in plant products between the two partners. Furthermore, we simulate trade expansions under plausible negotiation outcomes. We find that a TTIP agreement promotes cross-Atlantic trade in plant products, in both directions, by over 60% if tariffs are removed and MRLs are mutually recognized or harmonized to Codex levels.

description: The paper extends on the literature assessing China’s current “policy-oriented” agricultural insurance crop system to understand and to investigate the factors influencing the relative merits and potential demand for weather index crop insurance as a means for individual farmers in rural China to cope with weather-related production risks. Using the case of Huojia County in Henan Province, an empirical analysis is conducted of information collected from households’ survey and interviews with local village leaders. The key finding is that there is a significant potential demand for weather index crop insurance product as households seek time-efficient risk management strategies although this demand is influenced by generally poor awareness of insurance, small areas, and relatively low profitability of crop production.

description: Simultaneously optimizing performances, processability and fabrication cost of organic electronic materials is the continual source of compromise hindering the development of disruptive applications. In this work, we identified a strategy to achieve record conductivity values of one of the most benchmarked semiconducting polymers by doping with an entirely solution-processed, water-free and cost-effective technique. High electrical conductivity for poly(3-hexylthiophene) up to 21 S/cm has been achieved, using a commercially available electron acceptor as both a Lewis acid and an oxidizing agent. While we managed water-free solution-processing a three-time higher conductivity for P3HT with a very affordable/available chemical, near-field microscopy reveals the existence of concentration-dependent higher-conductivity micro-domains for which furthermore process optimization might access to even higher performances. In the perpetual quest of reaching higher performances for organic electronics, this work shall greatly unlock applications maturation requiring higher-scale processability and lower fabrication costs concomitant of higher performances and new functionalities, in the current context where understanding the doping mechanism of such class of materials remains of the greatest interest.
Expression and function of semaphorin4F in the developing and adult rat nervous system

description: Traumatic injury to the mature peripheral or central nervous system results in different regenerative outcomes. In the peripheral nervous system (PNS), neurons that suffer an axonal injury will typically mount a successful regenerative response, leading to target reinnervation and functional recovery. Conversely, in the central nervous system (CNS), neurons do not mount a strong regenerative response after axonal injury, and thus fail to regenerate and functionally reinnervate their targets. This lack of CNS axonal regeneration and functional recovery is manifested in the permanent and devastating paralysis endured by individuals who suffer a spinal cord injury. Given the dissimilar regenerative outcomes between the CNS and PNS, elucidating the factors that contribute to this distinction--particularly those that promote successful regeneration in the PNS--may help us develop methods by which to promote functional regeneration of injured adult CNS neurons. Semaphorins are a family of growth-promoting (chemoattractive) and growth-inhibiting (chemorepulsive) proteins that, by virtue of their influence on axonal growth, may be important factors in regeneration after injury. In this thesis, I examined the expression of one member of this family, Semaphorin4F (Sema4F), in the adult vertebrate nervous system following axonal injury. I addressed the question: Does the expression of Sema4F in axotomized neurons coincide with the regenerative potential of the injured neuronal population? I found that neuronal populations able to mount a robust regenerative response after axonal injury also upregulate their expression of Sema4F, a process not observed in neurons lacking this response. This correlation between Sema4F expression following axotomy and the regenerative ability of the particular adult neuronal population suggests that Sema4F may play a positive role in the regenerative process. Furthermore, I also asked the question: Can Sema4F inhibit the extension of embryonic sensory neurites in culture? I determined that while neuronally-expressed Sema4F may function as a growth promoting cue in the injured adult PNS, in vitro , it functions as a membrane-bound, non-permissive cue to ’slow’ or ’stall’ the extension of embryonic-day-13 DRG neurites across HEK 293 cell islands. These findings suggest that Sema4F may play a multifaceted role in the developing and mature nervous system.

description: We review the general properties of the intracluster medium (ICM) in clusters that host a cooling flow, and in particular the effects on the ICM of the injection of hot plasma by a powerful active galactic nucleus (AGN). It is observed that, in some cases, the hot plasma produces cavities in the ICM that finally detach and rise, perhaps buoyantly. The gas dynamics induced by the rising bubbles can help explain the absence of a cooled gas component in clusters with a cooling flow. This scenario is explored using numerical simulations.
