Phenotype and genotype characterization of Monilinia spp. isolates and preformed antifungal compounds in peach peel fruit at different developmental stages
Creators: name: Martini, Camilla <1984>

Subjects: AGR/12 Patologia vegetale

description: The brown rot fungi belong to a group of fungal pathogens that causes considerable damage to cultivated fruits trees, particularly stone fruits and apples in the temperate regions of the World and during the postharvest with an important economic impact. In particular in Italy, it is important to monitor the Monilinia population to control economic losses associated to the peach and nectarine market. 
This motivates the research steps presented in this dissertation on Monilinia Italian isolates. The Monilinia species collected from stone fruits have been identified using molecular analysis based on specific primers. The relevant role of M. fructicola was confirmed and, for the first time, it was found also on apple fruits.
To avoid the development of resistant strains and implement valid treatment strategies, the understanding of the fruit natural resistance during different developmental stages and the assessment of the Monilinia sensitivity/resistance to fungicides are required. 
The relationship between the inhibition spots and the phenolic compounds in peach fruit peel was highlighted in this research.
Three methods were used to assess isolate resistance/sensitivity, the amended medium, the Spiral Gradient Endpoint Method (SGD) and the Alamar Blue method. 
The PCR was used to find possible mutation points in the b-tubulin gene that is responsible for fungicide resistance. Interestingly, no mutation points were observed in resistant M. laxa isolates, suggesting that the resistance could be stimulated by environmental factors. 


This lead to the study of the effect of the temperature on the resistance and the preliminary results of in vitro tests showed that maximum inhibition was observed at 30°C.

description: This work presents the results of theoretical and experimental characterization of thermodynamic, mechanical and transport properties in polymer solvent systems. The polymer solvent pairs considered ranged to those in which the polymer is rubbery, to those in which the initially glassy polymeric matrix is plasticized by the action of the low molecular weight species. Advanced Equation of State models have been adopted for thermodynamic modeling,along with a rigorous procedure that enables to extend their applicability to the non equilibrium, glassy region. Mass sorption kinetics had been modeled with phenomenological models and with advanced kinetic models.
description: Questo lavoro verte sulla caratterizzazione teorica e sperimentale delle proprietà termodinamiche, meccaniche e di trasporto di sistemi polimero-solvente. In particolare sono stati presi in considerazione sia sistemi polimero-solvente in cui la matrice polimerica si trova allo stato di gomma, che sistemi in cui la matrice polimerica esibisce comportamento vetroso, nonché sistemi nei quali si verifica la transizione vetrosa indotta dall'effetto plasticizzante del solvente. La modellazione termodinamica è stata effettuata utilizzando equazioni di stato avanzate e metodi idonei ad estenderne il campo di utilizzo alla condizione di non equilibrio, propria dello stato vetroso. Cinetiche di assorbimento non Fickiane sono state modellate utilizzando approcci fenomenologici e modelli cinetici avanzati.
Development of strategies for vascular damage repair in Pulmonary Arterial Hypertension

description: Pulmonary arterial hypertension (PAH) is a progressive and rare disease with so far unclear pathogenesis, limited treatment options and poor prognosis. Unbalance of proliferation and migration in pulmonary arterial smooth muscle cells (PASMCs) is an important hallmark of PAH.
In this research Sodium butyrate (BU) has been evaluated in vitro and in vivo models of PAH. This histone deacetylase inhibitor (HDACi) counteracted platelet-derived growth factor (PDGF)-induced ki67 expression in PASMCs, and arrested cell cycle mainly at G0/G1 phases. Furthermore, BU reduced the transcription of PDGFRbeta, and that of Ednra and Ednrb, two major receptors in PAH progression. Wound healing and pulmonary artery ring assays indicated that BU inhibited PDGF-induced PASMC migration. BU strongly inhibited PDGF-induced Akt phosphorylation, an effect reversed by the phosphatase inhibitor calyculinA.
In vivo, BU showed efficacy in monocrotaline-induced PAH in rats. Indeed, the HDACi reduced both thickness of distal pulmonary arteries and right ventricular hypertrophy.
Besides these studies, Serial Analysis of Gene Expression (SAGE) has be used to obtain complete transcriptional profiles of peripheral blood mononuclear cells (PBMCs) isolated from PAH and Healthy subjects. SAGE allows quantitative analysis of thousands transcripts, relying on the principle that a short oligonucleotide (tag) can uniquely identify mRNA transcripts. Tag frequency reflects transcript abundance. We enrolled patients naïve for a specific PAH therapy (4 IPAH non-responder, 3 IPAH responder, 6 HeritablePAH), and 8 healthy subjects. Comparative analysis revealed that significant differential expression was only restricted to a hundred of down- or up-regulated genes. Interestingly, these genes can be clustered into functional networks, sharing a number of crucial features in cellular homeostasis and signaling. SAGE can provide affordable analysis of genes amenable for molecular dissection of PAH using PBMCs as a sentinel, surrogate tissue.
Altogether, these findings may disclose novel perspectives in the use of HDACi in PAH and potential biomarkers.

description: In seguito ad una disamina del materiale presente in letteratura, ci siamo chiesti se i numerosi investimenti pubblicitari, promozionali, di marketing e, per dirla in una parola sola “intangibili”, generassero un aumento del valore dell’impresa nel contesto valutativo oppure se dessero origine esclusivamente ad aumenti di fatturato. L’obiettivo più ambito consiste nel capitalizzare gli investimenti su attività intangibili come la costruzione del marchio, l’utilizzo di brevetti, le operazioni rivolte alla soddisfazione del cliente e tutto quanto si possa definire immateriale. Eppure coesistono nel mare magnum della stessa azienda. Fino a quando non si potrà inserire criteri di valutazione d’azienda delle performance di marketing non ci potrà essere crescita in quanto, le risorse, sono utilizzate senza un criterio di ritorno di investimento.
description: The analysis of the various methods of business valuation is begun through an examination of the traditionally used witnesses for the instruction of the appraisal matter, continuation from enriched specific witnesses of examples and concluded through a carried out bibliographical analysis on international specific articles. Afterwards to an examination of the material present in literature, we have wondered ourselves if the numerous advertising investments, marketing and, in order to say it in a single word “intangible”, they generated an increase of the value of the enterprise in the valuation context or if they exclusively gave origin to turnover increases. The which aimed at objective more consists in capitalizing the investments on intangible activities like the construction of the brand, the use of licenses, the operations turned to the customer satisfaction and all how much can be defined immaterial. To define a financial method of measurement of a not financial asset represents the fulcrum of the search. The results evidence that the financial market currency positively the intangible investments, but, in spite of everything, considers theoretical the measurement of the monetary value of the same ones. The habit of the companies is that to measure the effects of a cost reduction of production and, more in general terms, than all this that is material, while they do not control minimally as the undertaken actions immaterial generate or they do not generate profit.

description: The assumption this article is based on is that guilt is perhaps the most important theme in Alois Hotschnig’s writing. This article therefore aims at analyzing Hotschnig’s focus on the theme of guilt in his novels. Three examples of Hotschnig’s prose work serve as case studies: his debut Aus, and the two novels Leonardos Hände, and Ludwigs Zimmer. Since guilt seems to be a very important topic in the Austrian literary tradition, this article also tries to establish whether and how Hotschnig takes up this grand Austrian tradition of writing about guilt.

Subjects: L-LIN/10 Letteratura inglese

description: Il lavoro si propone un’analisi dell’elemento spaziale e del movimento per ricostruire lo spazio della cultura neozelandese e lo spazio letterario di Janet Frame. La tesi si concentra in particolar modo sui romanzi con alcune incursioni nella fiction breve e nell’autobiografia. Si sviluppa in quattro capitoli nella forma di un itinerario attraverso la fiction dell'autrice preceduto da un capitolo che offre alcune coordinate teoriche e metodologiche sul concetto di spazio e la sua percezione. In particolare, una prospettiva fenomenologica e esistenziale alla questione appare congeniale all'analisi delle opere dell'autrice.
	Nell'ordine, quattro spazi concettuali si aprono a partire dai romanzi: linguaggio, etica, trascendenza e arte. Essi costituiscono i nuclei tematici e strutturali attorno ai quali si raccolgono i romanzi di Janet Frame e che consentono di analizzare i luoghi descritti nelle opere proponendo però una riflessione che va oltre la rappresentazione dello spazio per aprirsi sul retroterra culturale, intellettuale e filosofico dell'autrice. Emerge così l'originalità della sua posizione rispetto all'identità culturale del suo paese e alla relazioni che legano la Nuova Zelanda alla metropoli inglese e agli altri Paesi anglosassoni.
description: The thesis is an analysis of the concept of space and its representations in the novels of Janet Frame. Geography, movements, travels, places and dwellings are the basic elements that are examined in order to reveal the cultural and philosophical background of the author. In this perspective, both as an intellectual and as a fiction writer, Frame reveals her extremely original position in relation to some crucial issues such as New Zealand identity and the cross-cultural ties between the English-speaking countries.

description: The effect of soil incorporation of 7 Meliaceae derivatives (6 commercial neem cakes and leaves of Melia azedarach L.) on C and N dynamics and on nutrient availability to micropropagated GF677 rootstock was investigated. In a first laboratory incubation experiment the derivatives showed different N mineralization dynamics, generally well predicted by their C:N ratio and only partly by their initial N concentration. All derivatives increased microbial biomass C, thus representing a source of C for the soil microbial population. Soil addition of all neem cakes (8 g kg-1) and melia leaves (16 g kg-1) had a positive effect on plant growth and increased root N uptake and leaf green colour of micropropagated plants of GF677. In addition, the neem cakes characterized by higher nutrient concentration increased P and K concentration in shoot and leaves 68 days after the amendment. In another experiment, soil incorporation of 15N labeled melia leaves (16 g kg-1) had no effect on the total amount of plant N, however the percentage of melia derived-N of treated plants ranged between 0.8% and 34% during the experiment. At the end of the growing season, about 7% of N added as melia leaves was recovered in plant, while 70% of it was still present in soil. Real C mineralization and the priming effect induced by the addition of the derivatives were quantified by a natural 13C abundance method. The real C mineralization of the derivatives ranged between 22% and 40% of added-C. All the derivatives studied induced a positive priming effect and, 144 days after the amendment, the amount of C primed corresponded to 26% of added-C, for all the derivatives. Despite this substantial priming effect, the C balance of the soil, 144  days after the amendment, always resulted positive.

description: Staphylococcus aureus is a Gram positive pathogen that causes various human infections and represents one of the most common causes of bacteremia. S. aureus is able to invade a variety of non-professional phagocytes and that can survive engulfment by neutrophils, producing both secreted and surface components that compromise innate immune responses. In the contest of our study we evaluated the functional activity of vaccine specific antibodies by opsonophagocytosis killing assay (OPKA). Interestingly a low level of killing of the staphylococcal cells has been observed. In the meanwhile intracellular survival studies showed that S. aureus persisted inside phagocytes for several hours until a burst of growth after 5 hours in the supernatant. These data suggest that the strong ability of S. aureus to survive in the phagocytes could be the cause of the low killing measured by OPKA. Moreover parallel studies on HL-60 cells infected with S. aureus done by using transmission electron microscopy (TEM) interestingly showed that staphylococcal cells have an intracellular localization (endosomal vacuoles) and that they are able not only to maintain the  integrity of their membrane but also to replicate inside vacuolar compartments. Finally in order to generate 3D volume of whole bacteria when present inside neutrophilic vacuoles, we collected a series of tomographic two-dimensional (2D) images by using a transmission electron microscope, generating 5 different tomograms. The three-dimensional reconstruction reveals the presence of intact bacteria within neutrophil vacuoles. The S. aureus membrane appears completely undamaged and integral in contrast with the physiological process of phagosytosis through vacuoles progression. S. aureus bacteria show a homogenous distribution of the density in all the three dimensions (X, Y, Z). All these evidences definitely explain the ability of the pathogen to survive inside the endosomal vacuoles and should be the cause of the low killing level.

description: Elfriede Jelineks postdramatic drama Death and the Maiden I represents a feminist revision of the fairy tale Snow White by the Brothers Grimm. Jelinek applies the ideologically and patriarchally loaded medium “fairy tale” to develop a highly differentiated feminist criti­cism on Western philosophy. Thus, this adaption has to be put in the context of the pre-existing intertext by Brothers Grimm, feminist literary criticism and deconstruction. This essay examines where and how Jelinek instrumentalizes and modifies popular fairy tale motifs in order to create a multi-layered criticism of ontological gender paradigms, patri­archal structures in philosphical thinking, and ideals of beauty.

description: Observations of astronomical objects in the far ultraviolet (FUV wavelengths span 900-1800Å) from earth's orbit has been impeded due to bright Lyman-α geocoronal emission. The Johns Hopkins Rocket Group is developing a hydrogen absorption cell that would act as a narrow band Lyman-α rejection filter to enable space-based photometric observation in bandpasses that span over the Lyman ultraviolet region shortward of the geocoronal line. While this technology has been applied to various planetary missions with single element photomultiplier detectors it has yet to be used on near earth orbiting satellites with a multi-element detector. We are working to develop a cell that could be easily incorporated into future Lyman ultraviolet missions. The prototype cell is a low-pressure (~ few torr) chamber sealed between a pair of MgF2 windows allowing transmission down to 1150 Å. It is filled with molecular hydrogen that is converted to its neutral atomic form in the presence of a hot tungsten filament, which allows for the absorption of the Lyman-α photons. Molecular hydrogen is stored in a fully saturated non-evaporable getter module (St707TM), which allows the cell pressure to be increased under a modest application of heat (a 20 degree rise from room temperature has produced a rise in pressure from 0.6 to 10 torr). Testing is now underway using a vacuum ultraviolet monochromator to characterize the cell optical depth to Lyman-α photons as functions of pressure and tungsten filament current. We will present these results, along with a discussion of enabled science in broadband photometric applications.

description: Knowledge of X-ray shock and radio relic connection in merging galaxy clusters has been greatly extended in terms of both observation and theory over the last decade. ZwCl 2341+0000 is a double-relic merging galaxy cluster; previous studies have shown that half of the S relic is associated with an X-ray surface brightness discontinuity, while the other half not. The discontinuity was believed to be a shock front. Therefore, it is a mysterious case of an only partial shock-relic connection. By using the 206.5 ks deep Chandra observations, we aim to investigate the nature of the S discontinuity. Meanwhile, we aim to explore new morphological and thermodynamical features. In addition, we utilize the GMRT and JVLA images to compute radio spectral index (SI) maps. In the deep observations, the previously reported S surface brightness discontinuity is better described as a sharp change in slope or as a kink, which is likely contributed by the disrupted core of the S subcluster. The radio SI maps show spectral flattening at the SE edge of the S relic, suggesting that the location of the shock front is 640 kpc away from the kink. We update the radio shock Mach number to be $2.2\pm0.1$ and $2.4\pm0.4$ for the S and N radio relics, respectively, based on the injection SI. We also put a 3 sigma lower limit on the X-ray Mach number of the S shock to be >1.6. Meanwhile, the deep observations reveal that the N subcluster is in a perfect cone shape, with a ~400 kpc linear cold front on each side. This type of conic subcluster has been predicted by simulations but is observed here for the first time. It represents a transition stage between a blunt-body cold front and a slingshot cold front. Strikingly, we found a 400 kpc long gas trail attached to the apex of the cone, which could be due to the gas stripping. In addition, an over-pressured hot region is found in the SW flank of the cluster.

Simple pion-nucleon and pion-nucleus potentials with applications of the doorway model to pion-nucleus scattering
Creators: name: Rowe, Glenn William
Publisher: name: University of British Columbia
Year: 2010

description: The pion-nucleon total cross section is reproduced in the pion kinetic energy range of zero to 250 MeV by a simple Yukawa potential with the depth.and width as free parameters. This potential is then averaged over a nuclear matter distribution in an attempt to produce a pion-nucleus potential for pion-¹²C scattering. The model is explored by varying several parameters in the potential and observing their effect on the differential cross section for pion-12C scattering with the pion kinetic energy equal to 50 MeV. No completely satisfactory fit to the data is found. It is suggested that treating this system as a pion-nucleon system interacting in the average field of the residual nucleus may give better results and some ideas are presented as to how this might be done. Applications of such a treatment of pion-nucleus interactions to the description of pion-nucleus "doorway" states (so far, apart from the N*, unobserved) are discussed.

description: To ensure high availability, datacenter networks must rely on local fast rerouting mechanisms that allow routers to quickly react to link failures, in a fully decentralized manner. However, configuring these mechanisms to provide a high resilience against multiple failures while avoiding congestion along failover routes is algorithmically challenging, as the rerouting rules can only depend on local failure information and must be defined ahead of time. This paper presents a randomized local fast rerouting algorithm for Clos networks, the predominant datacenter topologies. Given a graph $G=(V,E)$ describing a Clos topology, our algorithm defines local routing rules for each node $v\in V$, which only depend on the packet's destination and are conditioned on the incident link failures. We prove that as long as number of failures at each node does not exceed a certain bound, our algorithm achieves an asymptotically minimal congestion up to polyloglog factors along failover paths. Our lower bounds are developed under some natural routing assumptions.
Delay-rate tradeoff for ergodic interference alignment in the Gaussian case

description: In interference alignment, users sharing a wireless channel are each able to achieve data rates of up to half of the non-interfering channel capacity, no matter the number of users. In an ergodic setting, this is achieved by pairing complementary channel realizations in order to amplify signals and cancel interference. However, this scheme has the possibility for large delays in decoding message symbols. We show that delay can be mitigated by using outputs from potentially more than two channel realizations, although data rate may be reduced. We further demonstrate the tradeoff between rate and delay via a time-sharing strategy. Our analysis considers Gaussian channels; an extension to finite field channels is also possible.

After mapping the error-correction process onto a statistical mechanical random 3-body Ising model on a Union Jack lattice, we compute its phase diagram in the temperature-disorder plane using Monte Carlo simulations. Surprisingly, topological color codes on Union Jack lattices have similar error stability than color codes on triangular lattices, as well as the Kitaev toric code. The enhanced computational capabilities of the topological color codes on Union Jack lattices with respect to triangular lattices and the toric code demonstrate the inherent robustness of this implementation.

description: A practical quantum key distribution (QKD) protocol necessarily runs in finite time and, hence, only a finite amount of communication is exchanged. This is in contrast to most of the standard results on the security of QKD, which only hold in the limit where the number of transmitted signals approaches infinity. Here, we analyze the security of QKD under the realistic assumption that the amount of communication is finite. At the level of the general formalism, we present new results that help simplifying the actual implementation of QKD protocols: in particular, we show that symmetrization steps, which are required by certain security proofs (e.g., proofs based on de Finetti's representation theorem), can be omitted in practical implementations. Also, we demonstrate how two-way reconciliation protocols can be taken into account in the security analysis. At the level of numerical estimates, we present the bounds with finite resources for ``device-independent security'' against collective attacks.

As a concrete example we investigate a nonrelativistic field theory with instantaneous interaction where the flow equations can be solved exactly. However, the formalism is more general and can be applied to relativistic field theories, as well. We also discuss expansion schemes that can be used to find approximate solutions of the flow equations including the essential momentum dependence.

description: Inference of the network structure (e.g., routing topology) and dynamics (e.g., link performance) is an essential component in many network design and management tasks. In this paper we propose a new, general framework for analyzing and designing routing topology and link performance inference algorithms using ideas and tools from phylogenetic inference in evolutionary biology. The framework is applicable to a variety of measurement techniques. Based on the framework we introduce and develop several polynomial-time distance-based inference algorithms with provable performance. We provide sufficient conditions for the correctness of the algorithms. We show that the algorithms are consistent (return correct topology and link performance with an increasing sample size) and robust (can tolerate a certain level of measurement errors). In addition, we establish certain optimality properties of the algorithms (i.e., they achieve the optimal $l_\infty$-radius) and demonstrate their effectiveness via model simulation.

description: We study a quantum model with non-isotropic two-dimensional oscillator potential but with additional quadratic interaction $x_1x_2$ with imaginary coupling constant. It is shown, that for a specific connection between coupling constant and oscillator frequences, the model {\it is not} amenable to a conventional separation of variables. The property of shape invariance allows to find analytically all eigenfunctions and the spectrum is found to be equidistant. It is shown that the Hamiltonian is non-diagonalizable, and the resolution of the identity must include also the corresponding associated functions. These functions are constructed explicitly, and their properties are investigated. The problem of $R-$separation of variables in two-dimensional systems is discussed.

description: We present a two-dimensional heterotic N=(0,2) CP(N-1) model with twisted masses. It is supposed to describe internal dynamics of non-Abelian strings in massive N=2 SQCD with N=1-preserving deformations. We present gauge and geometric formulations of the world-sheet theory and check its N=(0,2) supersymmetry. It turns out that the set of twisted masses in the heterotic model has N complex mass parameters, rather than N-1. In the general case, when all mass parameters are nonvanishing, N=(0,2) supersymmetry is spontaneously broken already at the classical level. If at least one of the above mass parameters vanishes, then N=(0,2) is unbroken at the classical level. The spontaneous breaking of supersymmetry in this case occurs through nonperturbative effects.

Effect of sensor to segment alignment errors on IMU-based running joint angle estimates

Body-worn inertial measurement units (IMUs) are increasingly utilized to capture human performance in real-world scenarios (e.g., during training or competition). For example, many physics-based sensor fusion methods combine raw IMU data with kinematic and anatomical constraints to estimate human joint angles. For running and sprinting, lower-limb joint angles show importance in many traditional indoor camera-based biomechanical studies; however, translation to real-world studies requires further advances in the IMU-based methods. Beyond the well-known challenge of correcting integration drift errors, a primary challenge towards accurate IMU-only estimation of joint angles is the accurate estimation of sensor-tosegment alignment (S2S) parameters (i.e., the relative orientation and location of the IMU and anatomical ‘xyz’ frames). However, the minimum S2S accuracy that is required for accurate joint angle estimates is largely unexplored due in part to the presence of other confounding error sources in experimental studies (e.g., soft tissue artefacts). In this study, 96 000 simulations are used to better investigate the impact of S2S parameter errors on the accuracy of IMU-based lower-limb joint angle estimates during running.
Elizabethan justifications for violence in Ireland
Creators: name: Tronrud, Thorold John
Publisher: name: University of British Columbia

description: Violence was a central feature of Anglo-Irish relations in the latter half of the sixteenth century. Besides the devastation brought about by organized warfare there were many incidents of violence of an extraordinary nature—violence employed in times of truce.as well as war, exercised against, non-combatants of all ages, and often carried out with extreme cruelty. Such destruction evoked extensive response from many English gentry serving as officials and administrators in Ireland. Their private and official accounts of the Irish people and the Irish problem serve as the basis of my study. This thesis will be an analysis of how these Elizabethan gentry attempted to justify their violence, to legitimate it in the face of external opposition, and to rationalize it within their own minds. I will attempt to discover why Elizabethans found it necessary to justify their actions in the intricate manner in which they did, and what this may tell us about the intellectual development of the English gentry throughout the sixteenth century. An examination of the attitudes and policies of sixteenth-century Englishmen towards Ireland reveals that a great change took place over a relatively short period of time. Accounts and policies dating from the reign of Henry VIII were both lenient and sympathetic towards the Irish whereas those from the reign of Elizabeth were, by and large, brutal. This change was to occur mainly during the period of the Protectorate in England at a time when military force and religious persecution became the primary tools by which Ireland could be brought to 'civility'. The works dating from the reign of Elizabeth were, in large part, a response to.the extraordinary violence which began at the mid-century and to the psychological tensions that such destruction created. For this reason, I have relied, to a limited extent, upon modern psychological theories to help explain some aspects of the Elizabethan justifications. Finally, I am stating, as propositions, two conclusions. First, I propose that in the latter half of the sixteenth century the English and the Irish thought out and formulated ideas on two distinct intellectual planes and, as a consequence, were unable to fully comprehend the motives and aspirations of each other. This, I suggest, negated the possibility of a lasting peace in the sixteenth century and seriously hampered future attempts at reconciliation. Secondly, I submit that in their attempts to analyse and describe Ireland and to justify the violence perpetrated in that land, Englishmen were forced to re-examine their own society and to re-evaluate their role within it. It is possible, therefore, that their experience in Ireland was one of the numerous factors which helped many Englishmen break with the intellectual bonds of the past and to think in new and distinctive ways.
The power of flexible lattice in Ca3Ru2O7: Exquisite control of the electrical transport via anisotropic magnetostriction

description: Ca3Ru2O7 is a correlated and spin-orbit-coupled system with an extraordinary anisotropy. It is both interesting and unique largely because this material exhibits conflicting phenomena that are often utterly inconsistent with traditional precedents, particularly, the quantum oscillations in the nonmetallic state and colossal magnetoresistivity achieved by avoiding a fully spin-polarized state. This work focuses on the relationship between the lattice and transport properties along each crystalline axis and reveals that application of magnetic field, H, along different crystalline axes readily stretches or shrinks the lattice in a uniaxial manner, resulting in distinct electronic states. Furthermore, application of modest pressure drastically amplifies the anisotropic magnetoelastic effect, leading to either an occurrence of a robust metallic state at H || hard axis or a reentrance of the nonmetallic state at H || easy axis. Ca3Ru2O7 presents a rare lattice-dependent magnetotransport mechanism, in which the extraordinary lattice flexibility enables an exquisite control of the electronic state via magnetically stretching or shrinking the crystalline axes, and the spin polarization plays an unconventional role unfavorable for maximizing conductivity. At the heart of the intriguing physics is the anisotropic magnetostriction that leads to exotic states.

description: Massive protostars dramatically influence their surroundings via accretion-induced outflows and intense radiation fields. They evolve rapidly, the disk and infalling envelope being evaporated and dissipated in $\sim$ 10$^5$ years. Consequently, they are very rare and investigating this important phase of early stellar evolution is extremely difficult. Here we present the discovery of a key transient phase in the emergence of a massive young star, in which ultraviolet radiation from the new-born giant has just punctured through its natal core. The massive young stellar object AFGL 961 II is readily resolved in the near infrared. Its morphology closely resembles a cat's eye and is here dubbed as the Rosette Eye. Emerging ionized flows blow out an hourglass shaped nebula, which, along with the existence of strong near-infrared excess, suggests the existence of an accretion disk in the perpendicular direction. The lobes of the hourglass, however, are capped with arcs of static H$_{2}$ emission produced by fluorescence. This study has strong implications for our understanding of how massive stars embark on their formation.

description: We show that the growth of the heterostructure LaGaO3/SrTiO3 yields the formation of a highly conductive interface. Our samples were carefully analyzed by high resolution electron microscopy, in order to assess their crystal perfection and to evaluate the abruptness of the interface. Their carrier density and sheet resistance are compared to the case of LaAlO3/SrTiO3 and a superconducting transition is found. The results open the route to widening the field of polar-non polar interfaces, pose some phenomenological constrains to their underlying physics and highlight the chance of tailoring their properties for future applications by adopting suitable polar materials.
