description: Recent spectroscopic studies at terahertz frequencies for a variety of multiferroics endowed with both ferroelectric and magnetic orders have revealed the possible emergence of a new collective excitation, frequently referred to as electromagnon. It is magnetic origin, but becomes active in response to the electric field component of light. Here we give an overview on our recent advance in the terahertz time-domain spectroscopy of electromagnons or electric-dipole active magnetic resonances, focused on perovskite manganites--$R$MnO$_3$ ($R$ denotes rare-earth ions). The respective electric and magnetic contributions to the observed magnetic resonance are firmly identified by the measurements of the light-polarization dependence using a complete set of the crystal orientations. We extract general optical features in a variety of the spin ordered phases, including the $A$-type antiferromagnetic, collinear spin ordered, and ferroelectric $bc$ and $ab$ spiral spin ordered phases, which are realized by tuning the chemical composition of $R$, temperature, and external magnetic field. In addition to the antiferromagnetic resonances of Mn ions driven by the magnetic field component of light, we clarify that the electromagnon appears only for light polarized along the a-axis even in the collinear spin ordered phase and grows in intensity with evolution of the spiral spin order, but independent of the direction of the spiral spin plane ($bc$ or $ab$) or equivalently the direction of the ferroelectric polarization $P_{\rm s}$ ($P_{\rm s}\| c$ or $P_{\rm s}\| a$). A possible origin of the observed magnetic resonances at terahertz frequencies is discussed by comparing the systematic experimental data presented here with theoretical considerations based on Heisenberg model.

In the age of persistent, pervasive, and pandemic networks I review how the lattice QCD community embraced the open source paradigm for both code and data whilst adopting the emerging grid technologies, and why having your data persistently accessible via standardized protocols and services might be a good idea.

description: We investigate the presence of a central black hole (BH) in B023-G078, M31's most massive globular cluster. We present high-resolution, adaptive-optics assisted, integral-field spectroscopic kinematics from Gemini/NIFS that shows a strong rotation ($\sim$20 km/s) and a velocity dispersion rise towards the center (37 km/s). We combine the kinematic data with a mass model based on a two-component fit to $HST$ ACS/HRC data of the cluster to estimate the mass of a putative BH. Our dynamical modeling suggests a $>$3$σ$ detection of a BH component of 9.1$^{+2.6}_{-2.8}\times$10$^4$ M$_\odot$ (1$σ$ uncertainties). The inferred stellar mass of the cluster is 6.22$^{+0.03}_{-0.05}\times$10$^6$ M$_\odot$, consistent with previous estimates, thus the BH makes up 1.5% of its mass. We examine whether the observed kinematics are caused by a collection of stellar mass BHs by modeling an extended dark mass as a Plummer profile. The upper limit on the size scale of the extended mass is 0.56 pc (95% confidence), which does not rule out an extended mass. There is compelling evidence that B023-G078 is the tidally stripped nucleus of a galaxy with a stellar mass $>$10$^9$ M$_{\odot}$, including its high mass, two-component luminosity profile, color, metallicity gradient, and spread in metallicity. Given the emerging evidence that the central BH occupation fraction of $>$10$^9$ M$_{\odot}$ galaxies is high, the most plausible interpretation of the kinematic data is that B023-G078 hosts a central BH. This makes it the strongest BH detection in a lower mass ($

description: 6LowPAN was introduced by the IETF as a standard protocol to interconnect tiny and constrained devicesacross IPv6 clouds. 6LowPAN supports a QoS feature based on two priority bits. So far, little interest hasbeen granted and this QoS feature and there are no implementations of such feature in real networks. Inthis paper,we evaluate the capacity to provide QoS of these priority bits in various scenarios. We show thatunder very heavy or very low network load, these bits have a limited effect on the delay
Comparative Analysis of Direct Rehabilitation Costs of a Drainage System: CIPP versus Open-Cut Method

Publisher: name: Zenodo
Year: 2019

description: The purpose of this paper is to analyse the cost composition involved in a renovation project, comparing the traditional method with a rehabilitation technique using trenchless technology. We will focus specifically on the CIPP (Cured-In-Place Pipe) method and compare its costs with the traditional approach, limited to small diameters, specifically those less than DN 300.The CIPP method offers several advantages over the traditional method, including lower economic, social, and environmental impact, and is consistent with the principles of environmental sustainability. Industry literature does not typically calculate all the individual costs contributing to the total cost; instead, it often extracts project costs from various case studies, parameterizes them, and compares the results, particularly for small, medium, and large diameters.In this paper, costs are presented but not calculated, due to the inherent difficulties in identifying specific figures, which goes beyond the scope of this document. To clarify the analysis, some examples of cost composition for common configurations in practical applications will be provided. These examples reflect scenarios typically managed by building managers or network authorities overseeing wastewater, water, and irrigation systems.The study demonstrates the economic advantages of applying the CIPP method in large urban areas, where indirect costs, in particular, are more significant.

description: In order to evaluate and develop mission concepts for a search for Terrestrial Exoplanets, we have prepared a list of potential target systems. In this paper we present and discuss the criteria for selecting potential target stars suitable for the search for Earth like planets, with a special emphasis on the aspects of the habitable zone for these stellar systems. Planets found within these zones would be potentially able to host complex life forms. We derive a final target star sample of potential target stars, the Darwin All Sky Star Catalog (DASSC). The DASSC contains a sample of 2303 identified objects of which 284 are F, 464 G, 883 K, 615 M type stars and 57 stars without B-V index. Of these objects 949 objects are flagged in the DASSC as multiple systems, resulting in 1229 single main sequence stars of which 107 are F, 235 are G, 536 are K, and 351 are M type. We derive configuration dependent subcatalogs from the DASSC for two technical designs, the initial baseline design and the advanced Emma design as well as a catalog using an inner working angle cut off. We discuss the selection criteria, derived parameters and completeness of sample for different classes of stars.

Coarse graining dynamical triangulations: a new scheme

Publisher: name: arXiv
Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A new procedure for coarse-graining dynamical triangulations is presented. The procedure provides a meaning for the relevant value of observables when "probing at large scales", e.g. the average scalar curvature. The scheme may also be useful as a starting point for a new type of renormalisation procedure, suitable for dynamically triangulated quantum gravity. Random Delaunay triangulations have previously been used to produce discretisations of continuous Euclidean manifolds, and the coarse-graining scheme is an extension of this idea, using random simplicial complexes produced from a dynamical triangulation. In order for a coarse-graining process to be useful, it should preserve the properties of the original dynamical triangulation that are relevant when probing at large scales. Some general discussion of this point is given, along with some arguments in favour of the proposed scheme.

HI in very metal-poor galaxies: the SBS 0335-052 system

description: We present Giant Metrewave Radio Telescope (GMRT), HI 21cm observations of SBS 0335-052E and SBS 0335-052W, a close pair of dwarf galaxies, which are further unusual in being the most metal-poor star-forming galaxies known. We present images at several angular resolutions, ranging from ~40 to 4 arcsec. These images show that SBS 0335-052 is a strongly interacting system, with a faint diffuse HI bridge seen at low resolution, and elongated tails seen at the higher resolutions. The overall morphology suggests that the pair represents a major merger of extremely gas-rich galaxies. The low-resolution velocity field is dominated by the velocity difference between the two galaxies and the velocity gradient along the tidal features. However, for SBS 0335-052W at least, at high angular resolution, one sees a central velocity field that could be associated with the spin of the original undisturbed disc. The highest angular resolution HI images show that the ionized superbubble, identified by Thuan, Izotov & Lipovetsky (1997), in the Hubble Space Telescope (HST) images of SBS 0335-052E, is extended along one of the diffuse tidal features, and that there is a high-density HI clump at the other end of the superbubble. The star formation in SBS 0335-052E occurs mainly in a group of superstar clusters (SSCs) with a clear age gradient; the age decreases as one approaches the dense HI clump. We suggest that this propagating star formation is driven by the superbubble expanding into a medium with a tidally-produced density gradient. The high pressures associated with the compressed material would also naturally explain why current star formation is mainly concentrated in superstar clusters.

description: We consider the effect of non-constant parameters on the human-forest interaction logistic model coupled with human technological growth introduced in "Deforestation and world population sustainability: a quantitative analysis"[1]. In recent years in fact, a decrease in human population growth rate has emerged which can be measured to about 1.7% drop per year since 1960 value which coincides with latest UN projections for next decades up to year 2100 [2]. We therefore consider here the effect of decreasing human population growth-rate on the aforementioned model and we evaluate its effect on the probability of survival of human civilisation without going through a catastrophic collapse in population. We find that for realistic values of the human population carrying capacity of the earth (measured by parameter beta) this decrease would not affect previous results leading to a low probability of avoiding a catastrophic collapse. For larger more optimistic values of beta instead, a decrease in growth-rate would tilt the probability in favour of a positive outcome, i.e. from 10-20% up to even 95% likelihood of avoiding collapse.

description: Most of the currently known planets are small worlds with radii between that of the Earth and that of Neptune. The characterization of planets in this regime shows a large diversity in compositions and system architectures, with distributions hinting at a multitude of formation and evolution scenarios. Using photometry from the K2 satellite and radial velocities measured with the HARPS and CORALIE spectrographs, we searched for planets around the bright and slightly evolved Sun-like star HD 137496. We precisely estimated the stellar parameters, $M_*$ = 1.035 +/- 0.022 $M_\odot$, $R_*$ = 1.587 +/- 0.028 $R_\odot$, $T_\text{eff}$ = 5799 +/- 61 K, together with the chemical composition of the slightly evolved star. We detect two planets orbiting HD 137496. The inner planet, HD 137496 b, is a super-Mercury (an Earth-sized planet with the density of Mercury) with a mass of $M_b$ = 4.04 +/- 0.55 $M_\oplus$, a radius of $R_b = 1.31_{-0.05}^{+0.06} R_\oplus,$ and a density of $ρ_b = 10.49_{-1.82}^{+2.08}$ $\mathrm{g cm^{-3}}$. With an interior modeling analysis, we find that the planet is composed mainly of iron, with the core representing over 70% of the planet's mass ($M_{core}/M_{total} = 0.73^{+0.11}_{-0.12}$). The outer planet, HD 137496 c, is an eccentric ($e$ = 0.477 +/- 0.004), long period ($P$ = $479.9_{-1.1}^{+1.0}$ days) giant planet ($M_c\sin i_c$ = 7.66 +/- 0.11 $M_{Jup}$) for which we do not detect a transit. HD 137496 b is one of the few super-Mercuries detected to date. The accurate characterization reported here enhances its role as a key target to better understand the formation and evolution of planetary systems. The detection of an eccentric long period giant companion also reinforces the link between the presence of small transiting inner planets and long period gas giants.

Evidence for Magnetic Flux Saturation in Rapidly Rotating M Stars

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: We present magnetic flux measurements in seven rapidly rotating M dwarfs. Our sample stars have X-ray and H-alpha emission indicative of saturated emission, i.e., emission at a high level independent of rotation rate. Our measurements are made using near-infrared FeH molecular spectra observed with HIRES at Keck. Because of their large convective overturn times, the rotation velocity of M stars with small Rossby numbers is relatively slow and does not hamper the measurement of Zeeman splitting. The Rossby numbers of our sample stars are as small as 0.01. All our sample stars exhibit magnetic flux of kilo-Gauss strength. We find that the magnetic flux saturates in the same regime as saturation of coronal and chromospheric emission, at a critical Rossby number of around 0.1. The filling factors of both field and emission are near unity by then. We conclude that the strength of surface magnetic fields remains independent of rotation rate below that; making the Rossby number yet smaller by a factor of ten has little effect. These saturated M-star dynamos generate an integrated magnetic flux of roughly 3 kG, with a scatter of about 1 kG. The relation between emission and flux also has substantial scatter.

description: C’è una lacuna profonda nella storia italiana, un deficit di memoria che gli storici hanno raramente indagato e, in certi casi, hanno persino volutamente rimosso dalle loro cronache: si tratta dell’esperienza coloniale italiana perpetratasi dalla fine dell’Ottocento fino al termine della Seconda Guerra Mondiale, nel Dodecaneso, in Albania, in Libia, ma soprattutto nel Corno d’Africa. Esattamente con questa storia tenta di fare i conti Gabriele Proglio in Memorie oltre Confine. La letteratura postcoloniale italiana in prospettiva storica, nella consapevolezza che, come si può leggere nella citazione benjaminiana di apertura, «è più difficile onorare la memoria dei senza nome che non quella di chi è conosciuto. Alla memoria dei senza nome è consacrata la ricostruzione storica».

description: In order to solve backward parabolic problems F. John [{\it Comm. Pure. Appl. Math.} (1960)] introduced the two constraints "$\|u(T)\|\le M$" and $\|u(0) - g \| \le δ$ where $u(t)$ satisfies the backward heat equation for $t\in(0,T)$ with the initial data $u(0).$ The {\it slow-evolution-from-the-continuation-boundary} (SECB) constraint has been introduced by A. Carasso in [{\it SIAM J. Numer. Anal.} (1994)] to attain continuous dependence on data for backward parabolic problems even at the continuation boundary $t=T$. The additional "SECB constraint" guarantees a significant improvement in stability up to $t=T.$ In this paper we prove that the same type of stability can be obtained by using only two constraints among the three. More precisely, we show that the a priori boundedness condition $\|u(T)\|\le M$ is redundant. This implies that the Carasso's SECB condition can be used to replace the a priori boundedness condition of F. John with an improved stability estimate. Also a new class of regularized solutions is introduced for backward parabolic problems with an SECB constraint. The new regularized solutions are optimally stable and we also provide a constructive scheme to compute. Finally numerical examples are provided.

description: Large amounts of time and money are currently being spent in transferring computer programs from one machine to another. It seems unlikely that the problem of transferring such programs efficiently will ever be completely solved. What can be done, however, is to program in such a way that transfer costs are minimized. The first part of this paper discusses some effective techniques which have been developed to facilitate the writing of mobile programs. The second part discusses two detailed applications of one of these techniques, the use of an Abstract Logical Language.

description: Computer vision and multimedia information processing have made extreme progress within the last decade and many tasks can be done with a level of accuracy as if done by humans, or better. This is because we leverage the benefits of huge amounts of data available for training, we have enormous computer processing available and we have seen the evolution of machine learning as a suite of techniques to process data and deliver accurate vision-based systems. What kind of applications do we use this processing for ? We use this in autonomous vehicle navigation or in security applications, searching CCTV for example, and in medical image analysis for healthcare diagnostics. One application which is not widespread is image or video search directly by users. In this paper we present the need for such image finding or re-finding by examining human memory and when it fails, thus motivating the need for a different approach to image search which is outlined, along with the requirements of computer vision to support it.

description: (Abridged) We present numerical simulations of the formation of the planetary companions to 47 UMa, rho CrB, and 51 Peg. They are assumed to have formed in situ according to the basic model that a core formed first by accretion of solid particles, then later it captured substantial amounts of gas from the protoplanetary disk. In most of the calculations we prescribe a constant accretion rate for the solid core. The evolution of the gaseous envelope assumes that: (1) it is in quasi-hydrostatic equilibrium, (2) the gas accretion rate is determined by the requirement that the outer radius of the planet is the place at which the thermal velocity of the gas allows it to reach the boundary of the planet's Hill sphere, (3) the gas accretion rate is limited, moreover, by the prescribed maximum rate at which the nebula can supply the gas, and (4) the growth of the planet stops once it obtains approximately the minimum mass determined from radial velocity measurements. Calculations are carried out through an initial phase during which solid accretion dominates, past the point of crossover when the masses of solid and gaseous material are equal, through the phase of rapid gas accretion, and into the final phase of contraction and cooling at constant mass. Alternative calculations are presented for the case of 47 UMa in which the solid accretion rate is calculated, not assumed, and the dissolution of planetesimals within the gaseous envelope is considered. In all cases there is a short phase of high luminosity (1e-3-1e-2 Lsun) associated with rapid gas accretion. The height and duration of this peak depend on uncertain model parameters. The conclusion is reached that in situ formation of all of these companions is possible under some conditions. However, it is more likely that orbital migration was an important component of the evolution, at least for the planets around rho CrB and 51 Peg.

MOLECULAR MECHANISMS UNDERLYING CDC14 ACTIVATION DURING MITOTIC EXIT IN SACCHAROMYCES CEREVISIAE
Creators: name: MONTANI, FRANCESCA

description: In budding yeast, progression through anaphase and exit from mitosis are controlled by the conserved protein phosphatase Cdc14. The activity of Cdc14 is regulated in space and time by changes in its subcellular localization. For most of the cell cycle up to metaphase, the phosphatase is sequestered in the nucleolus, by binding to a competitive inhibitor called Cfi1 (also known as Net1) (Shou et al., 1999; Straight et al., 1999; Visintin et al., 1999). During anaphase, Cdc14 is released from its inhibitor by the sequential activation of two signaling cascades, the Cdc Fourteen Early Anaphase Release (FEAR) network and the Mitotic Exit Network (MEN). Once released Cdc14 spreads throughout the nucleus and the cytoplasm, where it reaches its targets and promotes progression through and exit from mitosis (Pereira et al., 2002; Shou et al., 1999; Stegmeier et al., 2002; Visintin et al., 1999; Yoshida et al., 2002). Several in vivo and in vitro observations suggest that phosphorylation of Cdc14 and/or Cfi1 is responsible for the dissociation of Cdc14 from its inhibitor. Three kinases have been implicated in the process: the polo-like kinase Cdc5, the Clb2-Cdk complex and the MEN kinase Dbf2 (Azzam et al., 2004; Geymonat et al., 2003; Hu and Elledge, 2002; Hu et al., 2001; Mohl et al., 2009; Pereira et al., 2002; Queralt et al., 2006; Stegmeier et al., 2002; Visintin et al., 2003; Yoshida and Toh-e, 2002). The aim of my project was to assess the contribution of the above-mentioned kinases and to identify the molecular mechanisms by which these kinases mediate the release of Cdc14 from its inhibitor. By modulating the kinases of interest alone or in mutual combination we found that Cdc14 is released from the nucleolus by the combined activity of two kinases, Cdc5 always and either Clb-Cdks or Dbf2. Once active, Cdc14 triggers a negative feedback loop that, in the presence of stable levels of mitotic cyclins, generates periodic cycles of Cdc14 release and sequestration. Similar phenotypes have been described for yeast bud formation and centrosome duplication. A common theme emerges where events that must happen only once per cycle, although intrinsically capable of oscillations, are limited to one occurrence by their coupling with the cyclin-Cdk cell cycle engine.

description: Polluted white dwarfs that have accreted planetary material provide a unique opportunity to probe the geology of exoplanetary systems. However, the nature of the bodies which pollute white dwarfs is not well understood: are they small asteroids, minor planets, or even terrestrial planets? We present a novel method to infer pollutant masses from detections of Ni, Cr and Si. During core--mantle differentiation, these elements exhibit variable preference for metal and silicate at different pressures (i.e., object masses), affecting their abundances in the core and mantle. We model core--mantle differentiation self-consistently using data from metal--silicate partitioning experiments. We place statistical constraints on the differentiation pressures, and hence masses, of bodies which pollute white dwarfs by incorporating this calculation into a Bayesian framework. We show that Ni observations are best suited to constraining pressure when pollution is mantle-like, while Cr and Si are better for core-like pollution. We find 3 systems (WD0449-259, WD1350-162 and WD2105-820) whose abundances are best explained by the accretion of fragments of small parent bodies ($<0.2M_\oplus$). For 2 systems (GD61 and WD0446-255), the best model suggests the accretion of fragments of Earth-sized bodies, although the observed abundances remain consistent ($<3σ$) with the accretion of undifferentiated material. This suggests that polluted white dwarfs potentially accrete planetary bodies of a range of masses. However, our results are subject to inevitable degeneracies and limitations given current data. To constrain pressure more confidently, we require serendipitous observation of (nearly) pure core and/or mantle material.

Reformation of an oblique shock observed by Cluster

description: On 16 March 2005, the Cluster spacecraft crossed a shock almost at the transition between the quasi-perpendicular and quasi-parallel regimes ($θ_{Bn}=46^{\circ}$) preceded by an upstream low-frequency ($\sim$ 0.02 Hz in the spacecraft frame) wavetrain observed for more than 10 mn. The wave semi-cycle nearest to the shock was found to grow in time, steepen and reflect an increasing fraction of the incoming ions. This gives strong indication that this pulsation is becoming a new shock front, standing $\sim 5λ_p$ upstream of the main front and growing to shock-like amplitude on a time-scale of $\sim 35Ω_p$. Downstream of the main shock transition, remnants of an older front are found indicating that the reformation is cyclic. This provides a unique example where the dynamics of shock reformation can be sequentially followed. The process shares many characteristics with simulations of reforming quasi-parallel shocks.
Conformal geometry in the four-dimensional Mobius space

description: In this thesis we study the geometry of surfaces immersed in the four-dimensional conformal sphere $Q_4$. It is known that a surface immersed in $Q_n$ is Willmore if and only if its conformal Gauss map is harmonic. Here we prove that a surface immersed in $Q_4$ is - or + isotropic if and only if its conformal Gauss map is, respectively, holomorphic or antiholomorphic. We make use of Cauchy-Riemann conditions to prove that, under suitable assumptions, a compact surface is either isotropic or its Euler characteristic is bounded from above. We then consider the notion of S-Willmore surface and prove that, even in the conformal setting, an S-Willmore surface is Willmore. We also prove that an isotropic surface is S-Willmore if and only if the curvature of the normal bundle associated with the surface does not vanish. Finally, we prove the existence of a bijection between the set of -isotropic, non totally umbilical, weakly conformal branched immersions of a fixed surface in $Q_4$, whose conformal gauss map can be continuously extended at the branch points, and non constant, holomorphic, totally isotropic maps with values in the conformal Grassmannian, with non constant associated map $J_\gamma$. The bijection is realized via the conformal gauss map

description: Professional astronomy is historically not an environment of diverse identities. In recognizing that public outreach efforts affect career outcomes for young people, it is important to assess the demographics of those being reached and continually consider strategies for successfully engaging underrepresented groups. One such outreach event, the International Astronomical Youth Camp (IAYC), has a 50-year history and has reached ~1700 participants from around the world. We find that the IAYC is doing well in terms of gender (59% female, 4.7% non-binary at the most recent camp) and LGBT+ representation, whereas black and ethnic minorities are lacking. In this proceeding, we report the current landscape of demographics applying to and attending the IAYC; the efforts we are making to increase diversity amongst participants; the challenges we face; and our future plans to bridge these gaps, not only for the benefit of the camp but for society overall.

EXPLORING THE MOLECULAR AND BIOPHYSICAL MECHANISMS OF PROTEOTOXIC IMMUNOGLOBULIN LIGHT CHAINS IN AL AMYLOIDOSIS
Creators: name: OBERTI, LUCA
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: Herein, immunoglobulin light chains (LCs) native state was studied in the context of the pathology known as light chain amyloidosis (AL). This pathology is characterized by LCs overexpression, which leads to toxicity and aggregation into amyloid fibrils in target organs, with heart being the most affected one. Due to genetic rearrangement and somatic hypermutation, virtually, each AL patient presents a different amyloidogenic LC (Merlini, 2017). Because of such complexity, the fine molecular determinants of LC aggregation propensity and proteotoxicity are, to date, unclear; significantly, their decoding requires investigating large sets of cases. This project is aimed to unravel the molecular determinants linked with LCs toxicity. First, we screened several independent biophysical and structural properties of the LCs native state. In particular, we considered hydrophobicity, fold stability, flexibility and 3D structure. Our experimental approach considered two LCs sets called ?H? and ?M?. The H set is composed of eight LCs from AL patients while the M set by LCs from multiple myeloma (MM) patients. M LCs were chosen as control since they are overexpressed as the toxic H LCs but they do not lead to toxicity or aggregation. To date, the molecular bases leading to LC proteotoxicity remain to be elucidated. Our data show that low fold stability and high protein flexibility correlate with amyloidogenic LCs, while hydrophobicity, structural rearrangements and nature of the LC dimeric association interface (as observed in seven crystal structures here presented) do not appear to play a significant role in protein aggregation. Additionally, it has been demonstrated that the LCs toxicity in vivo is linked to copper (Cu2+) (Diomede et al., 2017a) by increasing the radical oxygen species (ROS) production. We aimed our studied to clarify Cu2+ LCs interaction. Moreover, we wanted to assess whether Cu2+ is able to alter the biophysical properties of the native state to more aggregation prone states. Our findings reveal that H LCs interacts with Cu2+ with a higher affinity than M LCs and that His residues may be involved in Cu2+ binding. Indeed the affinity decreases in presence of protonated His residues. Moreover, data suggest that the interaction with Cu2+ increases the molecular flexibility and decreases the fold stability. These observations suggests that protein aggregation cannot be evaluated through one single parameters but by the co-action of several biophysical traits. Moreover, our results suggest that the presence of Cu2+ can alter the native LCs properties leading to a higher toxicity in vivo.
INFLUENCE OF DIETS AND DEVELOPMENTAL STAGES ON MICROBIOTA ASSOCIATED WITH THE INDIAN MEAL MOTH PLODIA INTERPUNCTELLA

description: Plodia interpunctella, also named indian meal moth (IMM), is considered a stored product pest due to its high polyphagous activity on a wide range of human food such as nuts, dry fruits and meat. Due to their ecology these pest can also carry a risk for the human health. However, to date, little is known on the microbial communities associated with this pest and the factors that may influence them. Recent studies highlighted the presence of three potential factors that may influence the bacteria community of moth pests, namely, diet, origin of the populations and the developmental stages. Due to scarcity of studies investigating the microbiota associated with P. interpunctella, I decided to investigate the bacterial community of this moth pest, using NGS approaches (454-pyrosequencing and Illumina platform). The aim of this thesis was to: i) evaluate the impact of different diets on the microbiota associated with P. interpunctella; ii) characterize the microbial community changes across different ontogenetic stages of P. interpunctella. In particular the possible effect of the diet on bacterial community of this pest was investigated by testing different diets (artificial diet, powder of Moringa oleifera leaves and Vicia faba beans for the laboratory reared population; Capsicum annuum chilli and white-black buckwheat for the wild/field populations) and among different life stages as eggs, first and last instar larvae and adults (both males and females). The main result showed that the only factor influencing the bacterial community associated to P. interpunctella was the diet, highlighting the presence of two different bacterial communities (entomotypes) in relation to the different nutrient composition of the diet (etomotype Atopococcus associated to moths reared on artificial diet and white- black buckewheat, entomotype Proprionibacterium associated to IMM reared on V. faba beans, C. annuum chilli and M. oleifera leaves). Moreover, the microbiota do not change among the analysed developmental stages of P. interpunctella and was dominated by the genus Burkholderia. The results achieved during the PhD program and reported in the present thesis were published as research articles (Evidence of a bacterial core in the stored products pest Plodia interpunctella: the influence of different diets; Evidence for a conserved microbiota across the different developmental stages of Plodia interpunctella and as review (New insights into the microbiota of moth pests).
