description: We present a comprehensive structure detection analysis of the 0.3 square degree area of the MUSYC-ACES field which covers the Chandra Deep Field-South (CDFS). Using a density-based clustering algorithm on the MUSYC and ACES photometric and spectroscopic catalogues we find 62 over-dense regions up to redshifts of 1, including, clusters, groups and filaments. All structures are confirmed using the DBSCAN method, including the detection of nine structures previously reported in the literature. We present a catalogue of all structures present including their central position, mean redshift, velocity dispersions, and classification based on their morphological and spectroscopic distributions. In particular we find 13 galaxy clusters and 6 large groups/small clusters. Comparison of these massive structures with published XMM-Newton imaging (where available) shows that $80\%$ of these structures are associated with diffuse, soft-band (0.4 - 1 keV) X-ray emission including $90\%$ of all objects classified as clusters. The presence of soft-band X-ray emission in these massive structures (${\rm M}_{200} \geq 4.9 \times 10^{13} {\rm M}_{\odot}$) provides a strong independent confirmation of our methodology and classification scheme. Nearly $60\%$ of the clusters, groups and filaments are detected in the known enhanced density regions of the CDFS at $z\simeq0.13$, $z\simeq0.52$, $0.68$, and $0.73$. Additionally, all of the clusters, bar the most distant, are found in these over-dense redshifts regions. Many of the clusters and groups exhibit signs of on-going formation seen in their velocity distributions, position within the detected cosmic web and in one case through the presence of tidally disrupted central galaxies exhibiting trails of stars. These results all provide strong support for hierarchical structure formation up to redshifts of 1.

description: Following infection of baboons with Schistosoma mansoni cercariae, a rapid four-fold increase in mean serum haptoglobin concentrations was observed. These concentrations dropped to near pre-infection levels following curative treatment of the infected animals with praziquantel. On challenge of the animals with a second cercarial dose, haptoglobin concentrations demonstrated a more gradual increase that did not attain the heights of the initial infection. Albumin concentrations displayed an inversely disproportionate relationship to those of haptoglobin and decreases were much less pronounced. Whereas albumin was not a sensitive indicator of schistosomiasis mansoni, haptoglobin proved to be useful in detecting the acute infection and in determining prognosis of the disease in the olive baboon.

description: Many hazards can interfere with the safety of the feeding stuffs intended to provide nutrients to experimental animals. Chemical and biological contaminants of laboratory animal feed can be a problem for toxicological and immunological research. Aflatoxin B1 (AFB1) is a secondary toxic metabolite, produced by the ubiquitous fungal genera, Aspergillus. AFB1 is particularly dangerous for health, inducing cancer of the urinary tract or liver carcinoma. The aim of this preliminary screening was to evaluate the presence of AFB1 in 31 samples of laboratory rat feed using a method validated in-house, then separated by High Pressure Liquid Chromatography (HPLC) coupled to a fluorescence detector. The detection limit (limit of detection: LOD) and the quantification limit (LOQ) were 0.2 and 0.4 ìg/kg respectively. Recoveries ranged from 58.0 to 74.5% for spiked samples. The immunoaffinity approach was significantly faster than methods employing conventional chromatography clean-up (Sep-Pak Classic Florisil and Sep-Pak ClassicC18 cartridges). Aflatoxins were not detected in any analysed sample.

description: Silverman and Stange defined the notion of an aliquot cycle of length $L$ for a fixed elliptic curve $E/\mathbb{Q}$, and conjectured an order of magnitude for the function that counts such aliquot cycles. We show that the conjectured upper bound holds for the number of aliquot cycles on average over the family of all elliptic curves with short bounds on the size of the parameters in the family.

description: Spontaneous behaviour in the home pen of group-housed minipigs was characterised with respect to social interaction, activity, locomotion, exploration and resting behaviour. Sixteen adult male and female Göttingen minipigs were allocated in three groups. Data were acquired at the age of seven and 16 months. Behaviour sampling was made by video recordings for two consecutive days per group. The median values for initiating and receiving social contact were one to four times per individual during 30 min of observation in the main “activity period” (found to be 4 – 4.30 pm with the feeding regime) at both ages; the variation between pigs was considerable. The animals spend a large amount of their active time (during this time) exploring (76 %). During the six-hours resting period, three bouts of activity were conspicuous in all three groups, and the highest level of activity was around midnight. The level of social interaction at seven and 16 months of age did not differ significantly, and the social hierarchy of the pigs in the three groups showed a high degree of consistency at seven and 16 months. However, correlation analysis did not indicate a statistically significant relationship between the level of social interaction of the individual pig at the young age and the older age. As relatively little is known about spontaneous behaviour of Göttingen minipigs this basal characterisation of normal behaviour may serve as normative data for future studies of Göttingen minipig behaviour.

description: In this article, we study the properties of metal contacts to single-layer molybdenum disulfide (MoS2) crystals, revealing the nature of switching mechanism in MoS2 transistors. On investigating transistor behavior as contact length changes, we find that the contact resistivity for metal/MoS2 junctions is defined by contact area instead of contact width. The minimum gate dependent transfer length is ~0.63 μm in the on-state for metal (Ti) contacted single-layer MoS2. These results reveal that MoS2 transistors are Schottky barrier transistors, where the on/off states are switched by the tuning the Schottky barriers at contacts. The effective barrier heights for source and drain barriers are primarily controlled by gate and drain biases, respectively. We discuss the drain induced barrier narrowing effect for short channel devices, which may reduce the influence of large contact resistance for MoS2 Schottky barrier transistors at the channel length scaling limit.

description: Broadband optical and narrowband Si XIII X-ray images of the young Galactic supernova remnant Cas A obtained over several decades are used to investigate spatial and temporal correlations on both large and small scales. The data consist of optical and near infrared ground-based and Hubble Space Telescope images taken between 1951 and 2011, and X-ray images from Einstein, ROSAT, and Chandra taken between 1979 and 2013. We find weak spatial correlations between the remnant's emission features on large scales, but several cases of good optical/X-ray correlations on small scales for features which have brightened due to recent interaction with the reverse shock. We also find instances where: (i) a time delay is observed between the appearance of a feature's optical and X-ray emissions, (ii) displacements of several arcseconds between a feature's X-ray and optical emission peaks and, (iii) regions showing no corresponding X-ray or optical emissions. To explain this behavior, we propose a inhomogeneous model for Cas A's ejecta consisting of small, dense optically emitting knots (n ~ 10^(2-3)/cm^(3)) and a much lower density (n ~ 0.1 - 1/cm^(3)) diffuse X-ray emitting component often spatially associated with optical emission knots. The X-ray emitting component is sometimes linked to optical clumps through shock induced mass ablation generating trailing material leading to spatially offset X-ray/optical emissions. A range of ejecta densities can also explain the observed X-ray/optical time delays since the remnant's 5000 km/s reverse shock heats dense ejecta clumps to temperatures around 3x10^4 K relatively quickly which then become optically bright while more diffuse ejecta become X-ray bright on longer timescales. Highly inhomogeneous ejecta as proposed here for Cas A may help explain some of the X-ray/opticalfeatures seen in other young core collapse SN remnants.

description: Laboratory animals are widely utilized in biomedical research, so a search of scientific publications can give us useful information on the use of animals. We retrieved the PubMed biomedicine database and searched for publications related to laboratory animals from 1966 to 2005. We found that rats and mice constitute the vast majority of species used in biomedical research; C57BL and BABL/c inbred mice, and Sprague Dawley and Wistar outbred rats are the most common strains. Recently, the numbers of publications relating to traditionally used animals such as rats, guinea pigs, dogs, cats, and sheep decreased slightly, whereas the numbers relating to mice, fish, Drosophila and Caenorhabditis elegans increased from 1995 to 2005, with annual mean growth rates of 4.5%, 8.22%, 1.95%, and 10.3%, respectively. Publications involving transgenic mice increased dramatically from the mid-1980s. This survey provides significant clues for predicting the future direction of biomedical research.

description: The aim of this thesis is to provide a framework that integrates the literature on the problems with student feedback engagement with student perspectives to provide an institutional roadmap to effective development of student engagement with feedback. Much of the current feedback research explores individual issues and problems with feedback without considering how these problems impact on each other. There is comparatively little available research on the impacts of institutional structures and policies and their impacts on feedback delivery and engagement, with little appreciation of the interplay between tutor teaching practices, student feedback engagement and what institutions do. Using a three-stage pragmatic mixed methods process, the research sought to identify, from the literature, the problem factors that inhibit assessment feedback engagement in higher education. It then identified the problem factors with feedback engagement from the student point of view. Finally, linkages between each of the eight problem factors identified were considered to conceptualise the interplay between the problem factors. The framework for enabling student development through feedback engagement was developed as the main output of this research. The significance of this study is that the framework presents a multilayered viewpoint on the linkages between the problems with feedback engagement, including student, staff, and institutional factors, giving readers a framework off which to hang future research, staff development, and institutional policies.

description: Oral bone grafting is a procedure widely performed in current dentistry. Several biomaterials fit this purpose. The aim of this study was to use scanning electron microscopy (SEM) to evaluate the ultrastructural aspects of bone repair in a rat model, with periodontal tissues involved. Two groups (I and II) of 20 animals each were operated on to create a surgical defect with a round carbide burr (3mm) on the right side of their mandible, anterior to the mental foramen. Both groups were evenly divided with 5 animals each to receive the application of either bifasic calcium phosphate bioceramic (B), lyophilized deproteinated bovine bone (L), bifasic bioceramic associated with lyophilized deproteinated bovine bone (BL), or no biomaterial (control or C). Group I was monitored for one week and group II for three weeks prior to euthanasia. Hemi-mandibles were prepared for SEM analysis. Parameters such as exposure of incisive root surface, width of the cross-section of filiform structures and presence of mineralized-like globuli (area) were evaluated. The findings of this study suggested that surgical procedures for introduction or not of biomaterial did not cause problems with normal feeding to the animals. Both of the biomaterials used promoted a periodontal ligament involvement. Fibers (single filiform structures) could be detected in a range from 0.07 to 0.18μm of diameter, except for L that was larger – considered to be due to residual fibers of bovine origin. C bundles (groups of fibers) showed larger width of cross-section than with the use of biomaterials. Globuli areas (mineralization) were smaller to C than with the biomaterials use. B showed larger globuli areas, suggesting slow incorporation. It was concluded that the use of these biomaterials favored maintenance of tissue volume although slowing remodeling, and the combination (BL) presented the best performance.

description: The Wide-field Infrared Survey Explorer (WISE) has scanned the entire sky with unprecedented sensitivity in four infrared bands, at 3.4, 4.6, 12, and 22 micron. The WISE Point Source Catalog contains more than 560 million objects, among them hundreds of thousands of galaxies with Active Nuclei (AGN). While type 1 AGN, owing to their bright and unobscured nature, are easy to detect and constitute a rather complete and unbiased sample, their type 2 counterparts, postulated by AGN unification, are not as straightforward to identify. Matching the WISE catalog with known QSOs in the Sloan Digital Sky Survey we confirm previous identification of the type 1 locus in the WISE color space. Using a very large database of the popular CLUMPY torus models, we find the colors of the putative type 2 counterparts, and also, for the first time, predict their number vs. flux relation that can be expected to be observed in any given WISE color range. This will allow us to put statistically very significant constraints on the torus parameters. Our results are a successful test of the AGN unification scheme.

description: The aim of the experiment was to study the effects of cage density (1, 3 and 5 rabbits per cage) and sex (male and female) on stress parameters of young rabbits. A total of 90 (45 male and 45 female) weaned New Zealand White rabbits aged 35 days old were used in the experiment. Rabbits were allocated as 1, 3 and 5 rabbits, in each of 5 cages, to obtain three different cage density groups: 4200, 1400 and 840 cm2 floor area per rabbit, respectively. Mean values for total body weight gain, food intake, food:gain ratio, the plasma corticosterone level and serum levels of glucose, cholesterol and triglycerides were taken as indicators of stress. The group having 5 rabbits per cage had significantly lower total body weight gain (p<0.001), food intake (p<0,001) and higher food:gain ratio (p<0,01) than other groups during the experiment. The levels of plasma corticosterone and serum glucose were higher (p<0.001) in the group with 5 rabbits per cage than other groups. Values for serum levels of cholesterol and triglyceride were not affected by cage density. Gender effect was detected only in corticosterone level. Male rabbits had higher plasma corticosterone than female rabbits. The results suggest that the allocation of 1 or 3 rabbits per cage had no measurable adverse effects on the welfare of male and female young rabbits, whereas (at our cage densities) 5 ones.

description: In a strain of inbred cotton rats, 25-50% of females develop spontaneous gastric hypochlorhydria and hypergastrinemia. Hypergastrinemic animals develop ECL cell derived gastric carcinomas located in the oxyntic mucosa, thus being an interesting animal model for studying the role of gastrin in gastric carcinogenesis. The response to gastric hypoacidity in cotton rats as regards the level of hypergastrinemia is far more pronounced than in the more commonly used laboratory rat. It is unknown whether the pronounced hypergastrinemic response in cotton rats is due to a greater population of G cells or a greater capacity of hormone synthesis in each G cell. The aim of the study was therefore to examine G cell population and ultrastructure in normogastrinemic and hypergastrinemic cotton rats by the use of immunhistochemical methods applied on both light- and electron-microscopy. Five hypergastrinemic vs. five normogastrinemic cotton rats were compared. Cotton rats with gastric hypochlorhydria have a 55-fold increase in serum gastrin levels and a 6-fold increase in G cell number, but this is not accompanied by significant changes in G cell ultrastructure. The lack of ultrastructural changes in these activated G cells indicates that previously reported changes in chronic stimulated G cells are just one of several ways G cells are activated.

description: We study the effect of a new fixator for treatment of diaphyseal bone fractures of small animal. The experiments were performed on 12 New Zealand White rabbits. Transverse osteotomy was made in the central third of the diaphysis of the rabbit’s femur and a rod-through-plate fixator was used to treat the bone fracture. The regeneration of the bone tissue was studied by means of radiography and histomorphology at postoperative weeks 2, 4 and 8. The rod-through-plate fixator gives stable fixation and early mobilisation of the limb. Radiographic images showed that the fractures had repaired well. Morphologically, all the parts of the callus had a typical structure. An immunohistochemical examination showed elevated levels of extracellular matrix proteins collagen type II, osteocalcin and osteopontin in the callus area. The new fixation method gives strong fixation of bone fragments with minimal traumatization of soft tissue during the operation. The construction of the rod-through-plate fixator allows one to reduce pressure in the area of the fracture and the dynamic fixation given by intramedullary rods allows micromotions stimulating callus formation and avoiding implant-induced osteoporosis. The fixator has a simple construction and its use expands the treatment possibilities for diaphyseal fractures of long bones. The rod-through-plate fixator use does not require special training for the surgeon.

description: Spectral and transport properties of small molecule single-crystal organic semiconductors have been theoretically analyzed focusing on oligoacenes, in particular on the series from naphthalene to rubrene and pentacene aiming to show that the inclusion of different electron-phonon couplings is of paramount importance to interpret accurately the properties of prototype organic semiconductors. While, in the case of rubrene, the coupling between charge carriers and low frequency inter-molecular modes is sufficient for a satisfactory description of spectral and transport properties, the inclusion of electron coupling to both low frequency inter-molecular and high frequency intra-molecular vibrational modes is needed to account for the temperature dependence of transport properties in smaller oligoacenes.

description: We have investigated the absorption cross section and the Hawking radiation of electromagnetic field with Weyl correction in the background of a four-dimensional Schwarzschild black hole spacetime. Our results show that the properties of the absorption cross section and the Hawking radiation depend not only on the Weyl correction parameter, but also on the parity of the electromagnetic field, which is quite different from those of the usual electromagnetic field without Weyl correction in the four-dimensional spacetime. With increase of Weyl correction parameter, the absorption probability, the absorption cross section, the power emission spectra and the luminosity of Hawking radiation decreases with Weyl correction parameter for the odd-parity electromagnetic field and increases with the event-parity electromagnetic field.

On the concept of pseudo-energy of T. G. Shepherd. A close link with exergy functions

description: Shepherd (1993) derived a general expression for the available potential energy for compressible, hydrostatic flow, where the sum of this available energy and the kinetic energy is called pseudo-energy. He demonstrated that for a special basic state the small-amplitude limit of the generalized available potential energy reduces to the well-known approximate form of Lorenz (1955) expressed in a pressure vertical coordinate. Other forms of available energies exist in atmospheric energetics and in thermodynamics, where the name exergy has been coined by Rant (1956) to denote the maximum work that can be extracted from any system when it is subject to some constraints (adiabatic transformations or constant total energy for instance). The purpose of this note is to show that the specific available enthalpy function denoted by $a_h = (h - h_r) - T_r \: (s - s_r)$ in Marquet (1991) can be obtained from the generalized approach of Shepherd for another basic state. This special form of pseudo-energy also leads to the global hydrostatic concepts of Dutton (1973) and Pichler (1977). The function $a_h$ only depends on the specific enthalpy $h$ and entropy $s$ at any point, the values $h_r$ and $s_r$ refer to the special dead state at temperature $T_r$ and pressure $p_r$. It is explained that for another choice of the basic state, the generalized expression of Shepherd reduces with a good accuracy to the approximate functions introduced by Pearce (1978) or Blackburn (1983) in meteorology and Thomson (1853, Lord Kelvin) in thermodynamics.

description: A common paradigm for improving fuzzing performance is to focus on selected regions of a program rather than its entirety. While previous work has largely explored how these locations can be reached, their selection, that is, the where, has received little attention so far. In this paper, we fill this gap and present the first comprehensive analysis of target selection methods for fuzzing. To this end, we examine papers from leading security and software engineering conferences, identifying prevalent methods for choosing targets. By modeling these methods as general scoring functions, we are able to compare and measure their efficacy on a corpus of more than 1,600 crashes from the OSS-Fuzz project. Our analysis provides new insights for target selection in practice: First, we find that simple software metrics significantly outperform other methods, including common heuristics used in directed fuzzing, such as recently modified code or locations with sanitizer instrumentation. Next to this, we identify language models as a promising choice for target selection. In summary, our work offers a new perspective on directed fuzzing, emphasizing the role of target selection as an orthogonal dimension to improve performance.
A Surgery Table with a Mouth Prop for Rodents

Year: 2014

description: Laboratory animal research represents a remarkable source of information. Rodents are often used as an experimental model for studies in the medical field, showing several advantages. The access to the oral cavity allows one to examine it and to perform surgical restorative procedures. The application of topical substances on hard tissues and mucosa is also possible. Literature includes reports on mouth-opening systems for animals, but they are not available on the market. Therefore, researchers must improvise methods that allow access to the oral cavity, but which may compromise the experiment. The purpose of this technical report is to introduce an inexpensive and easy-to-use surgery table containing a device for rodent mouth opening, which facilitates access to the oral cavity, maintaining mouth-opening and spreading the cheeks apart.

On Shift Dynamics For Cyclically Presented Groups

description: For group presentations with cyclic symmetry, there is a connection between asphericity and the dynamics of the shift automorphism. For the class of groups $G_n(k,l)$ described by the cyclic presentations $\mathcal{P}_n(k,l) = (x_i:x_ix_{i+k}x_{i+l}\ (i \mod n))$ and studied extensively by G. Williams and M. Edjvet \cite{EdjvetWilliams}, the shift acts freely on the nonidentity elements of $G_n(k,l)$ if and only if the presentation $\mathcal{P}_n(k,l)$ is combinatorially aspherical in the sense of \cite{CCH}. The shift has a nonidentity fixed point precisely when $G_n(k,l)$ is finite.
The co-evolution of galaxies and supermassive black holes in the near Universe

description: A fundamental role is attributed to supermassive black holes (SMBH), and the feedback they generate, in the evolution of galaxies. But theoretical models trying to reproduce the relation between the SMBH mass and stellar velocity dispersion of the galaxy bulge make broad assumptions about the physical processes involved. These assumptions are needed due to the scarcity of observational constraints on the relevant physical processes which occur when the SMBH is being fed via mass accretion in Active Galactic Nuclei (AGN). In search for these constraints, our group -- AGN Integral Field Spectroscopy (AGNIFS) -- has been mapping the gas kinematics as well as the stellar population properties of the inner few hundred parsecs of a sample of nearby AGN hosts. In this contribution, I report results obtained so far which show gas inflows along nuclear spirals and compact disks in the inner tens to hundreds of pc in nearby AGN hosts which seem to be the sources of fuel to the AGN. As the inflow rates are much larger than the AGN accretion rate, the excess gas must be depleted via formation of new stars in the bulge. Indeed, in many cases, we find ~100 pc circumnuclear rings of recent star formation (ages ~ 10 - 500 Myr) that can be interpreted as a signature of co-evolution of the host galaxy and its AGN.

Suitability of Permanent Probe Implants For the Measurement of Intramedullary Perfusion and Temperature Near the Bone Cortex: A Pilot Study Using a Rabbit Model

description: This study was conducted to test the suitability of permanent probe implants for the measurement of intramedullary perfusion by laser Doppler flowmetry and for the measurement of temperature near the bone cortex. Measurements were carried out on the conscious animal in order to rule out the influence of anaesthesia on intramedullary perfusion and temperature. During the first experimental animal trials, some of the probes made of polysulphon broke and/or gave false temperature measurements, so the original probe design was modified. The probes were reinforced with metal, and the temperature sensors were made less permeable to moisture. These modified probes were found to be suitable for permanent measurement of intramedullary perfusion and of temperature near the cortex in the conscious rabbit.

Nature of the Wiggle Instability of Galactic Spiral Shocks

description: Gas in disk galaxies interacts nonlinearly with an underlying stellar spiral potential to form galactic spiral shocks. While numerical simulations typically show that spiral shocks are unstable to wiggle instability (WI) even in the absence of magnetic fields and self-gravity, its physical nature has remained uncertain. To clarify the mechanism behind the WI, we conduct a normal-mode linear stability analysis as well as nonlinear simulations assuming that the disk is isothermal and infinitesimally thin. We find that the WI is physical, originating from the generation of potential vorticity at a deformed shock front, rather than Kelvin-Helmholtz instabilities as previously thought. Since gas in galaxy rotation periodically passes through the shocks multiple times, the potential vorticity can accumulate successively, setting up a normal mode that grows exponentially with time. Eigenfunctions of the WI decay exponentially downstream from the shock front. Both shock compression of acoustic waves and a discontinuity of shear across the shock stabilize the WI. The wavelength and growth time of the WI depend on the arm strength quite sensitively. When the stellar-arm forcing is moderate at 5%, the wavelength of the most unstable mode is about 0.07 times the arm-to-arm spacing, with the growth rate comparable to the orbital angular frequency, which is found to be in good agreement with the results of numerical simulations.

description: Over the last decades peritoneal dialysis (PD) has become a successful and widely used treatment for endstage renal disease patients worldwide. Together with the increasing number of uremic patients successfully treated with PD has grown an interest in physiological, pathophysiological and clinical aspects of this therapeutic method. This article provides an overview of the current status on animal models used in studying the histology and physiology of the peritoneum, as well as the process of peritoneal dialysis itself. We discuss species of experimental animals, methods of peritoneal access, sampling for histology, different techniques and methodologies, and complications of experimental models of PD.

description: The aim of this study was to establish a procedure for blood progenitor cell graft processing in rats. As a first step the mobilization protocol was optimized. The second step was dedicated to define the optimal source for subsequent graft manufacturing: either peripheral blood or spleen. The third step was designed to establish a protocol for purification of stem cells. The best mobilization results in terms of white blood cell count, granulocyte colony forming units (CFUG) and CD90 positive progenitor cells were obtained after pre-treatment of the donors for 5 days with recombinant human granulocyte colony stimulating factor (100 μg/kg) in combination with murine stem cell factor (33 μg/kg). Splenectomy prior to mobilization increased the yield of stem cells from peripheral blood. The numbers of CD90-positive progenitor cells recovered from the spleen of one rat after stem cell mobilization were sufficient to generate one stem cell graft. Grafts containing 1 x 106 progenitor cells – and thus sufficient for transplantation - were obtained after Tcell depletion and positive selection of CD90 positive cells. The grafts were characterized and showed a purity exceeding 70%, a T-cell depletion of 3.6 log10 and a 3-fold increase in CFU-G compared to the yield post mobilization.

description: Compressive displays are an emerging technology exploring the co-design of new optical device configurations and compressive computation. Previously, research has shown how to improve the dynamic range of displays and facilitate high-quality light field or glasses-free 3D image synthesis. In this paper, we introduce a new multi-mode compressive display architecture that supports switching between 3D and high dynamic range (HDR) modes as well as a new super-resolution mode. The proposed hardware consists of readily-available components and is driven by a novel splitting algorithm that computes the pixel states from a target high-resolution image. In effect, the display pixels present a compressed representation of the target image that is perceived as a single, high resolution image.
