description: We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the VLA and with Chandra, with which we measure the X-ray and radio spectral indices of jet knots, flux density variations in the jet knots, polarization variations, and proper motions. We compare the observed properties with current knot formation models and particle acceleration mechanisms. We rule out impulsive particle acceleration as a formation mechanism for all of the knots as we detect the same population of knots in all of the observations and we find no evidence of extreme variability in the X-ray knots. We find the most likely mechanism for all the stationary knots is a collision resulting in a local shock followed by a steady state of prolonged, stable particle acceleration and X-ray synchrotron emission. In this scenario, the X-ray-only knots have radio counterparts that are too faint to be detected, while the radio-only knots are due to weak shocks where no particles are accelerated to X-ray emitting energies. Although the base knots are prime candidates for reconfinement shocks, the presence of a moving knot in this vicinity and the fact that there are two base knots are hard to explain in this model. We detect apparent motion in three knots; however, their velocities and locations provide no conclusive evidence for or against a faster moving `spine' within the jet. The radio-only knots, both stationary and moving, may be due to compression of the fluid.

Kinetic energy and microcanonical nonanalyticities in finite and infinite systems

description: In contrast to the canonical case, microcanonical thermodynamic functions can show nonanalyticities also for finite systems. In this paper we contribute to the understanding of these nonanalyticities by working out the relation between nonanalyticities of the microcanonical entropy and its configurational counterpart. If the configurational microcanonical entropy $ω_N^c(v)$ has a nonanalyticity at $v=v_c$, then the microcanonical entropy $ω_N(ε)$ has a nonanalyticity at the same value $ε=v_c$ of its argument for any finite value of the number of degrees of freedom $N$. The presence of the kinetic energy weakens the nonanalyticities such that, if the configurational entropy is $p$ times differentiable, the entropy is $p+\lfloor N/2 \rfloor$-times differentiable. In the thermodynamic limit, however, the behaviour is very different: The nonanalyticities do not longer occur at the same values of the arguments, but the nonanalyticity of the microcanonical entropy is shifted to a larger energy. These results give a general explanation of the peculiar behaviour previously observed for the mean-field spherical model. With the hypercubic model we provide a further example illustrating our results.

The genesis of morphologies in extended radio sources: X-shapes, off-axis distortions and giant radio sources

description: We examine relationships between the morphology in double radio sources and the radio-optical position angle offset--the relative orientation of the radio axis with respect to the major axis of the host galaxy. The study was done for a representative sample of radio sources: the nearby (redshift z < 0.5) 3CRR sources, and separately for samples of giant radio sources and X-shaped radio sources. We find that radio morphological features have a dependence on the radio-optical position angle offset and on whether the source is a major- or minor-axis source. The evidence indicates an anisotropic galaxy environment, related to the ellipticity of the host galaxy, that causes the source linear size evolution, strength of backflow in the radio lobes, off-axis lobe distortions and the formation of wings and X-shaped radio sources to depend on the radio-optical position angle offset. We identify a class of X-shaped radio sources, which are either edge-darkened or lacking hotspots, and appear to have inner doubles suggesting a restarting of activity. We suggest a common formation mechanism, requiring backflows, for these apparently FR-I X-shaped radio sources as well as the edge-brightened X-shaped sources.

description: The “Luigi Cattaneo” Wax Museum houses the skull and wax bust of Luigi Marchetti, a man with acromegaly who died in 1808 at the age of 47 years. His case aroused the interest of many famous anatomists and nineteenth century clinicians including Rudolf Virchow. Cesare Taruffi’s study of this case and the exemplary and symbolic comparison between the exact wax replica and the human skull show how traumatic and complex this anatomical-pathological paradigm must have been for nineteenth century medical science. It also marks the historical continuity between endocrinological research in the old Bologna Anatomy School from Mondino Dei Liuzzi to Marcello Malpighi and Giovan Battista Morgagni and present-day expertise in pituitary neurosurgery at Bologna University and the city’s “Carlo Alberto Pizzardi” Bellaria Hospital.

description: If f(x_1, x_2, ..., x_n) is a polynomial dependent on a large number of independent Bernoulli random variables, what can be said about the maximum concentration of f on any single value? For linear polynomials, this reduces to one version of the classical Littlewood-Offord problem: Given nonzero constants a_1 through a_n, what is the maximum number of sums of the form +/- a_1 +/- a_2 +/-... +/- a_n which take on any single value? Here we consider the case where f is either a bilinear form or a quadratic form. For the bilinear case, we show that the only forms having concentration significantly larger than n^{-1} are those which are in a certain sense very close to being degenerate. For the quadratic case, we show that no form having many nonzero coefficients has concentration significantly larger than n^{-1/2}. In both cases the results are nearly tight.

description: In this study the phenotype and function of tumor-associated NK cells from perito- neal fluids of a selected cohort of patients with seropapillary ovarian carcinoma were analyzed. In >50% of these patients the expression of the activating receptor NKp30 (1) in tumor-associated NK cells was substantially reduced as compared to autolo- gous peripheral blood NK cells. The impaired expression of this receptor was associ- ated with the presence of one of its cellular ligands (B7-H6) (2), which was detectable as a surface/cytosolic molecule in tumor cells and as a soluble molecule in the peri- toneal fluid. NK cells from patients expressing this NKp30low phenotype displayed an impaired IFNγ production and cytolytic function when tested against target cells expressing surface B7-H6. Our data also suggest that in these patients the defective expression and function of NKp30 may be induced by the chronic engagement of this receptor by soluble B7-H6 or by tumor cells expressing this ligand. The impairment of NK cell functions described herein could represent a novel mechanism by which the tumor microenvironment may contribute to the escape from immune surveillance.

The interstitium at the developing nephron in the fetal kidney during advanced pregnancy — a microanatomical inventory

description: Background A series of noxae can evoke the termination of nephron formation in preterm and low birth weight babies. This results in oligonephropathy with severe consequences for health in the later life. Although the clinical parameters have been extensively investigated, little is known about the initial damage. Previous pathological findings indicate the reduction in width of the nephrogenic zone and the lack of S-shaped bodies. Current morphological investigations suggest that due to the mutual patterning beside the forming nephron, also its structural neighbors, particularly the interjacent interstitium, must be affected. However, beside the findings on integrative and mastering functions, systematic microanatomical data explaining the configuration of the interstitium at the developing nephron in the fetal kidney during advanced pregnancy is not available. Therefore, this work explains the typical features. Results The generated data depicts that the progenitor cells, nephrogenic niche, pretubular aggregate, and mesenchymal-to-epithelial transition are restricted to the subcapsular interstitium. During the proceeding development, only the distal pole of the renal vesicles and comma- and S-shaped bodies stays in further contact with it. The respective proximal pole is positioned opposite the peritubular interstitium at the connecting tubule of an underlying but previously formed nephron. The related medial aspect faces the narrow peritubular interstitium of a collecting duct (CD) ampulla first only at its tip, then at its head, conus, and neck, and finally at the differentiating CD tubule. The lateral aspect starts at the subcapsular interstitium, but then it is positioned along the wide perivascular interstitium of the neighboring ascending perforating radiate artery. When the nephron matures, the interstitial configuration changes again. Conclusions The present investigation illustrates that the interstitium at the forming nephron in the fetal kidney consists of existing, transient, stage-specific, and differently far matured compartments. According to the developmental needs, it changes its shape by formation, degradation, fusion, and rebuilding.

description: We investigate a system consisting of a single, as well as two emitters strongly coupled to surface plasmon modes of a nano-wire using a Green function approach. Explicit expressions are derived for the spontaneous decay rate into the plasmon modes and for the atom-plasmon coupling as well as a plasmon-mediated atom-atom coupling. Phenomena due to the presence of losses in the metal are discussed. In case of two atoms, we observe Dicke sub- and superradiance resulting from their plasmon-mediated interaction. Based on this phenomenon, we propose a scheme for a deterministic two-qubit quantum gate. We also discuss a possible realization of interesting many-body Hamiltonians, such as the spin-boson model, using strong emitter-plasmon coupling.

description: Mitosis is a highly regulated process characterized by dramatic and coordinated morphological changes to ensure the fidelity of chromosome segregation. Missegregation of mitotic chromosomes leads to a condition that underlies chromosomal instability(1), which is a hallmark of cancer. In order to assure symmetry and bipolarity of the cell division process, mitotic spindle microtubules properly segregate mitotic chromosomes (2). Among the several isoforms of serine/threonine kinases, PKCε is one of the best understood for its role as a transforming oncogene, and it has been found overexpressed in different types of tumors. In 2008, Saurin and colleagues demonstrated the involvement of PKCε in the regulation of the late stage of mitosis (3). Through its association with 14-3-3 at the midbody, PKCε is essential for the successful completion of cytokinesis, and the inhibition of functional PKCε-14-3- 3 complex leads to abscission failure and multinucleated phenotype in cells. In this study, we found that PKCε is involved in mitotic spindle stability. Using fluorescence microscopy, we found that the active form of PKCε (phosphorylated at Ser-729), colocalizes to the centrosome in cells in metaphase, where the mitotic spindle nucleation occurs. Furthermore, experiments of co-immunoprecipitation revealed that, when cells are synchronized in metaphase, PKCɛ is associated to ɣ-tubulin, a member of the tubulin superfamily localized to the microtubule organizing centers and is essential for microtubule nucleation from centrosomes. Consequently modulation of PKCɛ expression affects spindle stability: PKCɛ downregulation by specific shRNA results in mitotic spindle disorganization with a reduction of the amount of centrosomal and mitotic ɣ-Tubulin and αβ-tubulin fluorescence. Mitotic spindle formation assays using Nocodazole, known to interfere with the polymerization of microtubules, revealed that cells lacking PKCɛ were unable to regrow microtubules after depolymerization. These results reveal a novel role of PKCɛ in mitotic spindle stability, which likely determinant for genome stability.

description: Human trophoblastic cell surface antigen 2 (Trop-2) is a 40-kDa transmembrane glycoprotein, first identified as a cell surface marker for human trophoblast cells (1). Elevated expression of Trop-2 has been shown in several types of epithelial cancers and correlated with tumour aggressive and poor prognosis (2-3). The first aim of this study was to evaluate the variation of the Trop-2 expression in normal urothelium and urothelial bladder cancer. The immunohistochemical results showed an increase of Trop-2 levels in bladder cancer tissues with the increase of the severity of the pathology. Recent data identified Trop-2 as a target for miR-125b suggesting a pos sible role of miR-125b in the modulation of Trop-2 protein expression (4). The second aim was to verify if Trop-2 could be a target for miR-125b in bladder cells and to evaluate the possible role of miR-125b in the modulation of Trop-2 protein expression in normal bladder as well as in urothelial bladder cancer. In vitro we showed a contribution of miR-125b in deregulation of Trop-2 protein expression in a bladder cell line and we found that the expression of miR-125b was inversely correlated with the expression of Trop-2 protein on a cohort of bladder cancer tissues. We concluded to investigate in a larger population the use of Trop-2 and/or miR-125b as potential diagnostic markers in urothelial bladder cancer.

description: Pterygium is a chronic condition characterized by the encroachment of altered conjunctiva into the normal cornea. Several factors have been proposed as causative agents in the development of pterygium, however the exact mechanism of its pathogenesis is still unclear, even if several investigators consider pterygium an ultraviolet radiation (UV)-related disease. It is a relatively benign process, but since it displays tumor-like features, it has been proposed to be a neoplastic-like growth disorder (1). Vitamin D performs a number of functions outside of calcium homeostasis. Vitamin D status has been inversely associated with risk for various cancer, since Vitamin D inhibits cell proliferation, activates apoptotic pathways, inhibits angiogenesis, and exerts prodifferentiative effects in a wide variety of cancers (2). Since the antitumor actions of vitamin D are mediated primarily through Vitamin D receptor (VDR), and little is known about this subject in pterygium, the knowledge of VDR status may be important in understanding the pathogenesis of the disease. Keeping in mind all pathogenetic pterygium features, such as excessive cell proliferation, inflammation, fibrosis, extracellular matrix remodelling and intense neovascularization, we might suppose an alteration in the Vitamin D pathway. Therefore, the purpose of the study was to demonstrate, by immunohistochemistry on formalin-fixed and paraffin embedded sections of primary pterygium, the presence of VDR in pterygium, and to correlate it with the serum level of Vitamin D, in order to evaluate a possible role of Vitamin D pathway in the pathogenesis of the disease. The results will be discussed.

description: Hypermatrices are defined. Elementary operations and properties are defined and discussed. A 4-ary Multiplication is defined for hypermatrices, consisting of multilinear mappings from ordered 4-tuples of hypermatrices to hypermatrices. This multiplication is the only such mapping satisfying two basic properties which we should like such an operation to have. Various properties and characterizations of Multiplication are discussed. Equivalence Classes of hypermatrices are defined and discussed. Starting with equivalence classes of a general nature, we are led to the definition of various types of Hyperdeterminants, themselves considered as being equivalence classes of hypermatrices. Operators and operations on hypermatrices are extended to hyperdeterminants. A generalization of the Cauchy-Binet Theorem for matrices is seen to hold for hypermatrices and their associated hyperdeterminants. Special systems of hypermatrices are seen to constitute generalizations of the Complex and Quaternion Algebras, and some properties of these are discussed.

description: We introduce a new way to study molecular evolution within well-established Hamilton-Jacobi formalism, showing that for a broad class of fitness landscapes it is possible to derive dynamics analytically within the $1/N$-accuracy, where $N$ is genome length. For smooth and monotonic fitness function this approach gives two dynamical phases: smooth dynamics, and discontinuous dynamics. The latter phase arises naturally with no explicit singular fitness function, counter-intuitively. The Hamilton-Jacobi method yields straightforward analytical results for the models that utilize fitness as a function of Hamming distance from a reference genome sequence. We also show the way in which this method gives dynamical phase structure for multi-peak fitness.

description: Cholesteatoma is a noncancerous cystic lesion derived from an abnormal growth of keratinizing squamous epithelium in the temporal bone (1). It causes significant problems due to its erosive and expansile properties, resulting in the destruction of the ossicles. Over 5 million people worldwide are affected of cholesteatomas and gradually loss hearing. (2). In order to provide a prognostic tool useful during surgical procedures, we are performing a SEM morphological analysis of incus surface erosion due to cholesteatoma action; then we will investigate (on the same samples) the relationship among data from SEM analysis and genetical, proteomical, biochemical and histological data. Up to now we have observed 10 incus from patients with cholesteatoma. Samples were fixed immediately upon recovery in 2.5% glutaraldehyde in PBS at 4°C for 48 h, than they were prepared for scanning electron microscopy. Samples were gently sonicated before sputter coating, to remove excess of keratinizing squamous epithelium, that would have prevented erosion observation. The total surface area of the observed side was measured (3,54±0,21 mm2). The mean distance from the surgical removal point to the bone far end was measured in order to define a ROI (2,37±0,31 mm2). Five consecutive fields at 100X magnification aligned in 3 raws, the first one proximal and the last one distal to surgical removal point were analized. A total of 60 field for each raw were observed. Degree of erosion was classified as: No erosion=0, light =1, mild=2 high=3. Presence of biofilm was also recorded. Our early data suggest that although a gradient proximal to distal exists, looking to the distribution of eroded areas, grade 3 erosion is not limited only to the area proximal to cholesteatoma (first raw) but is also present in raw 2 and sometimes scattered since raw 3. Grade 3 erosion was observed around nutrient foramina of the bone (65%). Biofilm of bacteria was observed in 50% of analyzed fields, this is con- sistent with results reported in literature. Our data suggest that relapse of cholestea- toma is due to erosive activity of cells far from surgical removal point.

Bartonella schoenbuchii

description: Description of Bartonella schoenbuchii sp. nov. Bartonella schoenbuchii (schoen.buch«i.i. N.L. gen. n. schoenbuchii from Schonbuch, a nature park near Tubingen in south­west Germany where most of the roe deer analysed in this study were shot). Growth obtained on Columbia agar base supplemented with 5% defibrinated sheep blood in a moist atmosphere containing 5% CO. Colonies ap­ # pear in primary culture within 4–6 d as firm adherent, deeply invaginated, cauliflower­like colonies which upon passaging may switch to a more rapidly growing, shiny and smooth colony phenotype. The Gramnegative, monopolar politrichous flagellated rods are approximately 1–2‹0–5 lm, aerobic and negative for oxidase, indole, catalase and urea hydrolysis. The code for preformed enzymes obtained in the RapID ANA II system is 000 671. The biotype code using Rapid ID 32A was 0000 0737 05 or 0000 0337 05, depending on the strain analysed. The major fatty acids are cis ­11­ octadecanoic acid (C: x7 c), octadecanoic acid ") " (C) and hexadecanoic acid (C), similar as "):! "’:! observed for other Bartonella species. The four strains thus far isolated from the blood of healthy roe deer display phenotypic and genotypic differences but belong to a single new species. This new species is distinguished from previously known Bartonella species by the total protein profiles in SDS­PAGE, the banding patterns in the ERIC­PCR, the gltA and 16S rRNA gene sequences, and by whole­DNA hybridization analysis. Type strain is R 1 T, isolated from the blood of a 4­month­old female wild roe deer. Deposited in the National Collection of Type Cultures as NCTC 13165 T and the Deutsche Sammlung von Mikroorganismen und Zellkulturen as DSM 13525 T.

description: It is well known that neutrinoless double decay is going to play a crucial role in settling the neutrino properties, which cannot be extracted from the neutrino oscillation data. It is, in particular, expected to settle the absolute scale of neutrino mass and determine whether the neutrinos are Majorana particles, i.e. they coincide with their own antiparticles. In order to extract the average neutrino mass from the data one must be able to estimate the contribution all possible high mass intermediate particles. The latter, which occur in practically all extensions of the standard model, can, in principle, be differentiated from the usual mass term, if data from various targets are available. One, however, must first be able reliably calculate the corresponding nuclear matrix elements. Such calculations are extremely difficult since the effective transition operators are very short ranged. For such operators processes like pionic contributions, which are usually negligible, turn out to be dominant. We study such an effect in a non relativistic quark model for the pion and the nucleon.

description: We compute the massless five-point amplitude of open superstrings using the non-minimal pure spinor formalism and obtain a simple kinematic factor in pure spinor superspace, which can be viewed as the natural extension of the kinematic factor of the massless four-point amplitude. It encodes bosonic and fermionic external states in supersymmetric form and reduces to existing bosonic amplitudes when expanded in components, therefore proving their equivalence. We also show how to compute the kinematic structures involving fermionic states.

The ratio of $σ_L$ and $σ_T$ was extracted from the measured cross sections for $^1$H, $^2$H, $^{12}$C and $^{63}$Cu targets at $Q^2$ = 2.15 and 4.0 GeV$^2$ allowing for additional studies of the reaction mechanism. The experimental setup and the analysis of the data are described in detail including systematic studies needed to obtain the results. The results for the nuclear transparency and the differential cross sections as a function of the pion momentum at the different values of $Q^2$ are presented. Global features of the data are discussed and the data are compared with the results of model calculations for the p($e,e'π^{+}$)n reaction from nuclear targets.

description: Motivated by recent advances in vesicle engineering, we consider theoretically the locomotion of shape-changing bilayer vesicles at low Reynolds number. By modulating their volume and membrane composition, the vesicles can be made to change shape quasi-statically in thermal equilibrium. When the control parameters are tuned appropriately to yield periodic shape changes which are not time-reversible, the result is a net swimming motion over one cycle of shape deformation. For two classical vesicle models (spontaneous curvature and bilayer coupling), we determine numerically the sequence of vesicle shapes through an enthalpy minimization, as well as the fluid-body interactions by solving a boundary integral formulation of the Stokes equations. For both models, net locomotion can be obtained either by continuously modulating fore-aft asymmetric vesicle shapes, or by crossing a continuous shape-transition region and alternating between fore-aft asymmetric and fore-aft symmetric shapes. The obtained hydrodynamic efficiencies are similar to that of other low Reynolds number biological swimmers, and suggest that shape-changing vesicles might provide an alternative to flagella-based synthetic microswimmers.

description: Following a recent work of Dolan and Osborn, we consider superconformal indices of four dimensional ${\mathcal N}=1$ supersymmetric field theories related by an electric-magnetic duality with the SP(2N) gauge group and fixed rank flavour groups. For the SP(2) (or SU(2)) case with 8 flavours, the electric theory has index described by an elliptic analogue of the Gauss hypergeometric function constructed earlier by the first author. Using the $E_7$-root system Weyl group transformations for this function, we build a number of dual magnetic theories. One of them was originally discovered by Seiberg, the second model was built by Intriligator and Pouliot, the third one was found by Csáki et al. We argue that there should be in total 72 theories dual to each other through the action of the coset group $W(E_7)/S_8$. For the general $SP(2N), N>1,$ gauge group, a similar multiple duality takes place for slightly more complicated flavour symmetry groups. Superconformal indices of the corresponding theories coincide due to the Rains identity for a multidimensional elliptic hypergeometric integral associated with the $BC_N$-root system.
