Diencephalic asymmetries: morphological, immunohistochemical and ultrastructural analysis of habenular nuclei in elasmobranchs and teleosts

description: The habenular nuclei are diencephalic structures present in Vertebrates and they form, with the
associated fiber systems, a part of the system that connects the telencephalon to the ventral
mesencephalon (Concha M. L. and Wilson S. W., 2001). In representative species of almost all classes
of Vertebrates the habenular nuclei are asymmetric, both in terms of size and of neuronal and
neurochemical organization, although different types of asymmetry follow different evolutionary
courses. Previous studies have analyzed the spread and diversity of the asymmetry in species for which
data are not clear (Kemali M. et al., 1980). Notwithstanding that, it’s still not totally understood the
evolution of the phenomenon, and the ontogenetic mechanisms that have led to the habenular
asymmetry development are not clear (Smeets W.J. et al., 1983).
For the present study 14 species of Elasmobranchs and 15 species of Teleostean have been used.
Brains removed from the animals have been fixed using 4% paraformaldehyde in phosphate buffer;
brains have been analyzed with different tecniques, and I used histological, immunohistochemical and
ultrastructural analysis to describe this asymmetry.
My results confirm data previously obtained studying other Elasmobranchs species, in which the left
habenula is larger than the right one; the Teleostean show some slightly differences regarding the size
of the habenular ganglia, in some species, in which the left habenular nucleus is larger than the right.
In the course of studies, a correlation between the habits of life and the diencephalic asymmetry seems
to emerge: among the Teleostean analyzed, the species with benthic life (like Lepidorhombus boscii,
Platichthys flesus, Solea vulgaris) seem to possess a slight asymmetry, analogous to the one of the
Elasmobranchs, while in the other species (like Liza aurata, Anguilla anguilla, Trisopterus minutus)
the habenulae are symmetrical. However, various aspects of the neuroanatomical asymmetries of the
epithalamus have not been deepened in order to obtain a complete picture of the evolution of this
phenomenon, and new searches are needed to examine the species without clear asymmetry, in order to
understand the spread and the diversity of the asymmetry among the habenulae between the
Vertebrates.

description: Model checking is an automatic verification technique to verify hardware and software systems. However it suffers from state-space explosion problem. In this paper we address this problem in the context of cryptographic protocols by proposing a security property-dependent heuristic. The heuristic weights the state space by exploiting the security formulae; the weights may then be used to explore the state space when searching for attacks.

description: Due to their extraordinary physical and chemical properties carbon nanotubes reveal a promising potential as biomedical agents for heating, temperature sensoring and drug delivery on the cellular level. Filling carbon nanotubes with tailored materials realises nanoscaled containers in which the active content is encapsulated by a protecting carbon shell. We describe different synthesis routes and show the structural and magnetic properties of carbon nanotubes. In particular, the filling with magnetic materials offers the potential for hyperthermia applications while the insertion of NMR active substances allows the usage as markers and sensors. The potential of carbon nanotubes for biomedical applications is highlighted by hyperthermia studies which prove their applicability for local in-situ heating. In addition we have shown that a non-invasive temperature control by virtue of a carbon-wrapped nanoscaled thermometer and filling with anti-cancer drugs is possible.

description: The knee joint is a key structure of the human locomotor system. The
knowledge of how each single anatomical structure of the knee contributes
to determine the physiological function of the knee, is of fundamental
importance for the development of new prostheses and novel clinical,
surgical, and rehabilitative procedures. In this context, a modelling approach
is necessary to estimate the biomechanic function of each anatomical
structure during daily living activities.
The main aim of this study was to obtain a subject-specific model of the
knee joint of a selected healthy subject. In particular, 3D models of the
cruciate ligaments and of the tibio-femoral articular contact were proposed
and developed using accurate bony geometries and kinematics reliably
recorded by means of nuclear magnetic resonance and 3D video-fluoroscopy
from the selected subject.
Regarding the model of the cruciate ligaments, each ligament was
modelled with 25 linear-elastic elements paying particular attention to the
anatomical twisting of the fibres. The devised model was as subject-specific
as possible. The geometrical parameters were directly estimated from the
experimental measurements, whereas the only mechanical parameter of the
model, the elastic modulus, had to be considered from the literature because
of the invasiveness of the needed measurements. Thus, the developed model
was employed for simulations of stability tests and during living activities.
Physiologically meaningful results were always obtained. Nevertheless, the
lack of subject-specific mechanical characterization induced to design and
partially develop a novel experimental method to characterize the mechanics
of the human cruciate ligaments in living healthy subjects.
Moreover, using the same subject-specific data, the tibio-femoral articular
interaction was modelled investigating the location of the contact point
during the execution of daily motor tasks and the contact area at the full
extension with and without the whole body weight of the subject. Two
different approaches were implemented and their efficiency was evaluated.
Thus, pros and cons of each approach were discussed in order to suggest
future improvements of this methodologies.
The final results of this study will contribute to produce useful
methodologies for the investigation of the in-vivo function and pathology of
the knee joint during the execution of daily living activities. Thus, the
developed methodologies will be useful tools for the development of new
prostheses, tools and procedures both in research field and in diagnostic,
surgical and rehabilitative fields.

description: The MAGIC telescope is an imaging atmospheric Cherenkov telescope, designed to observe very high energy gamma-rays while achieving a low energy threshold. One of the key science goals is fast follow-up of the enigmatic and short lived gamma-ray bursts. The drive system for the telescope has to meet two basic demands: (1) During normal observations, the 72-ton telescope has to be positioned accurately, and has to track a given sky position with high precision at a typical rotational speed in the order of one revolution per day. (2) For successfully observing GRB prompt emission and afterglows, it has to be powerful enough to position to an arbitrary point on the sky within a few ten seconds and commence normal tracking immediately thereafter. To meet these requirements, the implementation and realization of the drive system relies strongly on standard industry components to ensure robustness and reliability. In this paper, we describe the mechanical setup, the drive control and the calibration of the pointing, as well as present measurements of the accuracy of the system. We show that the drive system is mechanically able to operate the motors with an accuracy even better than the feedback values from the axes. In the context of future projects, envisaging telescope arrays comprising about 100 individual instruments, the robustness and scalability of the concept is emphasized.

description: Cavity enhanced light scattering off an ultracold gas in an optical lattice constitutes a quantum measurement with a controllable form of the measurement back-action. Time-resolved counting of scattered photons alters the state of the atoms without particle loss implementing a quantum nondemolition (QND) measurement. The conditional dynamics is given by the interplay between photodetection events (quantum jumps) and no-count processes. The class of emerging atomic many-body states can be chosen via the optical geometry and light frequencies. Light detection along the angle of a diffraction maximum (Bragg angle) creates an atom-number squeezed state, while light detection at diffraction minima leads to the macroscopic superposition states (Schroedinger cat states) of different atom numbers in the cavity mode. A measurement of the cavity transmission intensity can lead to atom-number squeezed or macroscopic superposition states depending on its outcome. We analyze the robustness of the superposition with respect to missed counts and find that a transmission measurement yields more robust and controllable superposition states than the ones obtained by scattering at a diffraction minimum.

description: Modern high-energy physics experiments collect data using dedicated complex multi-level trigger systems which perform an online selection of potentially interesting events. In general, this selection suffers from inefficiencies. A further loss of statistics occurs when the rate of accepted events is artificially scaled down in order to meet bandwidth constraints. An offline analysis of the recorded data must correct for the resulting losses in order to determine the original statistics of the analysed data sample. This is particularly challenging when data samples recorded by several triggers are combined. In this paper we present methods for the calculation of the offline corrections and study their statistical performance. Implications on building and operating trigger systems are discussed.

description: Assessment of brain connectivity among different brain areas during cognitive or motor tasks is a crucial problem in neuroscience today. Aim of this research study is to use neural mass models to assess the effect of various connectivity patterns in cortical EEG power spectral density (PSD), and investigate the possibility to derive connectivity circuits from EEG data. To this end, two different models have been built. In the first model an individual region of interest (ROI) has been built as the parallel arrangement of three populations, each one exhibiting a unimodal spectrum, at low, medium or high frequency. Connectivity among ROIs includes three parameters, which specify the strength of connection in the different frequency bands. Subsequent studies demonstrated that a single population can exhibit many different simultaneous rhythms, provided that some of these come from external sources (for instance, from remote regions). For this reason in the second model an individual ROI is simulated only with a single population. Both models have been validated by comparing the simulated power spectral density with that computed in some cortical regions during cognitive and motor tasks.
Another research study is focused on multisensory integration of tactile and visual stimuli in the representation of the near space around the body (peripersonal space). This work describes an original neural network to simulate representation of the peripersonal space around the hands, in basal conditions and after training with a tool used to reach the far space. The model is composed of three areas for each hand, two unimodal areas (visual and tactile) connected to a third bimodal area (visual-tactile), which is activated only when a stimulus falls within the peripersonal space. Results show that the peripersonal space, which includes just a small visual space around the hand in normal conditions, becomes elongated in the direction of the tool after training, thanks to a reinforcement of synapses.

We derive a set of coupled gap equations and find that this system supports both spin-singlet and -triplet BCS pairs. We also calculate the critical temperatures and the angular dependence of order parameters. In addition, by tuning short-range interaction between inter-species molecules, the transition between singlet and triplet paired states may be realized.

description: We consider a quantum Universe composed by a small system S and a large environment. It has been demonstrated that, for the vast majority of randomly chosen wave-functions of the Universe satisfying a total energy constraint, the reduced density matrix of the system S is given by the canonical statistical distribution. Here, through the Page and Wootters mechanism, we show that time and non-equilibrium dynamics can emerge as a consequence of the entanglement between the system and the environment present in the (randomly chosen) global wave-function of the Universe. The clock is provided by the environment, which ticks the temporal evolution of S. The paradox of the peaceful coexistence of statistical equilibrium and non-equilibrium dynamics is solved by identifying the trace over the environment degrees of freedom with the temporal trace over the entire history of the system S.

description: We introduce a nonparametric graphical model for discrete node variables based on additive conditional independence. Additive conditional independence is a three-way statistical relation that shares similar properties with conditional independence by satisfying the semi-graphoid axioms. Based on this relation we build an additive graphical model for discrete variables that does not suffer from the restriction of a parametric model such as the Ising model. We develop an estimator of the new graphical model via the penalized estimation of the discrete version of the additive precision operator and establish the consistency of the estimator under the ultrahigh-dimensional setting. Along with these methodological developments, we also exploit the properties of discrete random variables to uncover a deeper relation between additive conditional independence and conditional independence than previously known. The new graphical model reduces to a conditional independence graphical model under certain sparsity conditions. We conduct simulation experiments and analysis of an HIV antiretroviral therapy dataset to compare the new method with existing ones. Supplementary materials for this article are available online.
Extinction and Distance to Anomalous X-ray Pulsars from X-ray Scattering Halos

description: We analyze the X-ray scattering halos around three Galactic Anomalous X-ray Pulsars (AXPs) in order to constrain the distance and the optical extinction of each source. We obtain surface brightness distributions from EPIC-pn data obtained with XMM-Newton, compare the profiles of different sources, and fit them with a model based on the standard theory of X-ray scattering by dust grains, both for a uniform distribution of dust along the line of sight, and for dust distributions constrained by previous measurements. Somewhat surprisingly, we find that for all three sources, the uniform distribution reproduces the observed surface brightness as well as or better than the distributions that are informed by previous constraints. Nevertheless, the inferred total dust columns are robust, and serve to confirm that previous measurements based on interstellar edges in high-resolution X-ray spectra and on modelling of broad-band X-ray spectra were reliable. Specifically, we find Av ~= 4, 6, and 8 mag for 4U 0142+61, 1E 1048.1-5937, and 1RXS J170849.0-400910, respectively. For 1E 1048.1-5937, this is well in excess of the extinction expected towards a HI bubble along the line of sight, thus casting further doubt on the suggested association with the source.

description: A heterotrophic-specialist model was proposed previously to divide wastewater treatment plant (WWTP) heterotrophs into sub-guilds of consumers of readily or slowly degradable substrates (RDS or SDS, respectively). The substrate degradation rate model coupled to metabolic considerations predicted that RNA and polyhydroxyalkanoate (PHA) levels would be positively correlated in the activated sludge communities with high RNA and PHA occurring in RDS-consumers, and low RNA with no PHA accumulation occurring in SDS-consumers because their external substrates are always present. This prediction was verified in previous studies and in the current one. Thus, RNA and PHA levels were used as biomarkers of the RDS- and SDS-consumer sub-guilds for cell sorting using flow cytometry of samples from three WWTPs. Subsequently, 16S rRNA gene amplicon sequencing revealed that the sorted groups were highly similar over time and among WWTPs, and demonstrated a clear segregation by RNA levels. Predicted ecophysiological traits based on 16S rRNA phylogeny suggested that the high-RNA population showed RDS-consumer traits such as higher rrn copy numbers per genome. Using a mass-flow immigration model, it appeared that the high-RNA populations exhibited high immigration rates more frequently than low-RNA populations, but the differences in frequencies were less with increasing solids residence times.

description: We report the discovery of an accreting binary, RAT J1953+1859, made during the RApid Temporal Survey (RATS) on the Isaac Newton Telescope. It showed high amplitude (0.3 mag) quasi-periodic oscillations on a timescale of ~20 mins. Further observations made using the Nordic Optical Telescope showed it to be ~4 mag brighter than in the discovery images. These photometric observations, together with radial velocity data taken using the William Herschel Telescope, point to an orbital period of ~90 mins. These data suggest that RAT J1953+1859 is a dwarf novae of the SU UMa type. What makes RAT J1953+1859 unusual is that it is the first such system to be discovered as a result of high amplitude QPOs during quiescence. This suggests that high-cadence wide-field surveys could be another means to discover cataclysmic variables as a result of their short period variability.

Ecology: Rare, a small population of 9–12 individuals was observed in a small area on moist slope at 3900–4000 m, Kunth Khal of Valley of Flowers National Park. The presence of A. nivalis and D. falconeri in the Valley of Flowers National Park on the one hand shows richness of flora, and on the other hand indicates better chances of survival of these rare species in the area where anthropogenic stresses are at a minimum. However, since the population sizes are very small, a close watch on the fate of these species is needed in future.

description: We propose a superlens formed by an ultra-dense array of crossed metallic wires. It is demonstrated that due to the anomalous interaction between crossed wires, the structured substrate is characterized by an anomalously high index of refraction and supports strongly confined guided modes with very short propagation wavelengths. It is theoretically proven that a planar slab of such structured material makes a superlens that may compensate for the attenuation introduced by free-space propagation and restore the subwavelength details of the source. The bandwidth of the proposed device can be quite significant since the response of the structured substrate is non-resonant. The theoretical results are fully supported by numerical simulations.

Quella a cui si farà riferimento è la scuola inglese “classica” riconosciuta come un corpo di pensiero derivante dall’opera di Martin Wight e Hedley Bull, e non la scuola inglese «moderna» o «nuova», che, in tempi più recenti, soprattutto nel corso degli anni ‘90, ha, più che altro, contribuito al successo della sua «invenzione» . Lo scopo è quello di mostrare, in primo luogo, come una delle caratteristiche distintive di questa scuola sia l’enfasi sulle regole, e, in special modo, sulle regole di diritto internazionale, sebbene in nessun posto la posizione di questi studiosi sull’argomento sia esposta in modo sistematico. Se la prima parte di questo lavoro, di tipo teoretico, tratta la questione della definizione operativa e della comprensione generale dell’istituzione del diritto internazionale, secondo l’approccio della scuola inglese classica, la seconda parte, di tipo empirico, tenta di verificare, tramite esemplificazioni storiche, tratte da eventi politici contemporanei, la validità delle principali conclusioni elaborate nella prima parte. E ciò con particolare riferimento alla distinzione, introdotta da Bull, delle due categorie analitiche di “pluralismo” e “solidarismo”, considerate come un’utile chiave di lettura per interpretare gli sviluppi della società internazionale e del diritto dopo la guerra fredda.

description: We present VLT intermediate resolution spectroscopy of UY Vol, the optical counterpart of the LMXB X-ray burster EXO 0748-676. By using Doppler tomography we detect narrow components within the broad He II 4542 A, 4686 A and 5412 A emission lines. The phase, velocity and narrowness of these lines are consistent with their arising from the irradiated hemisphere of the donor star, as has been observed in a number of LMXBs. Under this assumption we provide the first dynamical constraints on the stellar masses in this system. In particular, we measure K_2>K_em = 300 +/- 10 km/s. Using this value we derive 1 M_sun < M_1 < 2.4 M_sun and 0.11 < q < 0.28. We find M_1 > 1.5 M_sun for the case of a main sequence companion star. Our results are consistent with the presence of a massive neutron star as has been suggested by Ozel (2006), although we cannot discard the canonical value of ~1.4 M_sun.

description: In gasoline Port Fuel Injection (PFI) and Direct Injection (GDI) internal combustion engines, the liquid fuel might be injected into a gaseous ambient in a superheated state, resulting in flash boiling of the fuel. The importance to investigate and predict such a process is due to the influence it has on the liquid fuel atomization and vaporization and thus on combustion, with direct implications on engine performances and exhaust gas emissions. The topic of the present PhD research involves the numerical analysis of the behaviour of the superheated fuel during the injection process, in high pressure injection systems like the ones equipping GDI engines. Particular emphasis is on the investigation of the effects of the fuel superheating degree on atomization dynamics and spray characteristics.   
The present work is a look at the flash evaporation and flash boiling modeling, from an engineering point of view, addressed to keep the complex physics involved as simple as possible, however capturing the main characteristics of a superheated fuel injection.

description: The adiabatic connection of density functional theory (DFT) for electronic systems is generalized here to negative values of the coupling strength $α$ (with {\em attractive} electrons). In the extreme limit $α\to-\infty$ a simple physical solution is presented and its implications for DFT (as well as its limitations) are discussed. For two-electron systems (a case in which the present solution can be calculated exactly), we find that an interpolation between the limit $α\to-\infty$ and the opposite limit of infinitely strong repulsion ($α\to+\infty$) yields a rather accurate estimate of the second-order correlation energy $E\cor\glt[ρ]$ for several different densities $ρ$, without using virtual orbitals. The same procedure is also applied to the Be isoelectronic series, analyzing the effects of near-degeneracy.

description: Coincidences between charged particles emitted in the $β$-decay of $^{11}$Li were observed using highly segmented detectors. The breakup channels involving three particles were studied in full kinematics allowing for the reconstruction of the excitation energy of the $^{11}$Be states participating in the decay. In particular, the contribution of a previously unobserved state at 16.3 MeV in $^{11}$Be has been identified selecting the $α$ + $^7$He$\toα$ + $^6$He+n channel. The angular correlations between the $α$ particle and the center of mass of the $^6$He+n system favors spin and parity assignment of 3/2$^-$ for this state as well as for the previously known state at 18 MeV.

New insight on a Group A Streptococcus protective antigen contributing to bacterial cell division

Subjects: BIO/11 Biologia molecolare

description: Bioinformatic analysis of Group A Streptococcus (GAS) genomes aiming at the identification of new vaccine antigens, revealed the presence of a gene coding for a putative surface-associated protein, named GAS40, inducing protective antibodies in an animal model of sepsis. The aim of our study was to unravel the involvement of GAS40 in cell division processes and to identify the putative interactor. Firstly, bioinformatic analysis showed that gas40 shares homology with ezrA, a gene coding for a negative regulator of Z-ring formation during cell division process. Both scanning and transmission electron microscopy indicated morphological differences between wild-type and the GAS40 knock-out mutant strain, with the latter showing an impaired capacity to divide resulting in the formation of very long chains. Moreover, when the localization of the antigen on the bacterial surface was analyzed, we found that in bacteria grown at exponential phase GAS40 specifically localized at septum, indicating a possible role in cell division. Furthermore, by ELISA and co-sedimentation assays, we found that GAS40 is able to interact with FtsZ, a protein involved in Z-ring formation during cell division process. These data together with the co-localization of GAS40/FtsZ at bacterial septum demonstrated by by confocal microscopy, strongly support the hypothesis for a key role of GAS40 in bacterial cell division.
Obtainment of internal labelling operators as broken Casimir operators by means of contractions related to reduction chains in semisimple Lie algebras

description: We show that the Inönü-Wigner contraction naturally associated to a reduction chain $\frak{s}\supset \frak{s}^{\prime}$ of semisimple Lie algebras induces a decomposition of the Casimir operators into homogeneous polynomials, the terms of which can be used to obtain additional mutually commuting missing label operators for this reduction. The adjunction of these scalars that are no more invariants of the contraction allow to solve the missing label problem for those reductions where the contraction provides an insufficient number of labelling operators.
