Determining factors of Canadian milk quota prices
Creators: name: Ulheim, Jørn
Publisher: name: University of British Columbia
Year: 2009

description: Issues regarding the effects of supply management systems, seem to attract special attention from the industry, policy makers, and academic environments. The Canadian dairy industry is no exception. In addition to higher milk product prices for the consumer, the milk marketing quota is perhaps the most debated side of the dairy supply management regime. The milk quotas were initially allocated to each farmer, and are now traded openly in most provinces through a milk quota exchange. Substantial variation in milk quota prices can be observed in the last 15 years as compared to the TSE 300 Stock Price Index. The objective of this research is to analyze and explore why the large variation in observed milk quota prices in the 1980's and 1990's occurred, and to reveal the factors that are important for the formation of milk quota prices. Two factors are the focus of this thesis, one is the uncertainty regarding the future of the supply management system, especially during the two major trade negotiations, GATT and CUSTA, that took place in the late 1980's and early 1990's. The second is the expectations of future returns from holding milk production quotas that were formed in the presence of this uncertainty. Based on a standard capitalization model, three price functions are derived. Using an adaptive expectation framework, and one of the most complete data sets collected for the purpose of analyzing quota prices and quota issues in Ontario, Quebec, and Alberta, the estimated results suggest that, in general, unit changes in the net profit variable are important in MSQ pricing, more so for Used MSQ prices and fluid milk quota prices, than Unused MSQ prices. This supports the impression that fluctuations in Unused MSQ prices are partly driven by short-run considerations to avoid over-quota and maintenance penalties. The adaptive expectation model provides better results when explaining the formation of MSQ prices than fluid milk quota prices. This analysis also concludes that the milk quota auction is not a perfectly understood marketplace, and that several puzzles remain to be explained in future work.

description: Based on the {\it ab-initio} band structure for Na$_x$CoO$_2$ we derive the single-electron energies and the effective tight-binding description for the $t_{2g}$ bands using projection procedure. Due to the presence of the next-nearest-neighbor hoppings a local minimum in the electronic dispersion close to the $Γ$ point of the first Brillouin zone forms. Correspondingly, in addition to a large Fermi surface an electron pocket close to the $Γ$ point emerges at high doping concentrations. The latter yields the new scattering channel resulting in a peak structure of the itinerant magnetic susceptibility at small momenta. This indicates dominant itinerant in-plane ferromagnetic fluctuations above certain critical concentration $x_m$, in agreement with neutron scattering data. Below $x_m$ the magnetic susceptibility shows a tendency towards the antiferromagnetic fluctuations. We further analyze the many-body effects on the electronic and magnetic excitations using various approximations applicable for different $U/t$ ratio.

description: The present controversy over the origin of glasslike thermal conductivity observed in certain crystalline materials is addressed by studies on single-crystal x-ray diffraction, thermal conductivity k(T) and specific heat Cp(T) of carrier-tuned Ba8Ga16X30 (X = Ge, Sn) clathrates. These crystals show radically different low-temperature k(T) behaviors depending on whether their charge carriers are electrons or holes, displaying the usual crystalline peak in the former case and an anomalous glasslike plateau in the latter. In contrast, Cp(T) above 4 K and the general structural properties are essentially insensitive to carrier tuning. We analyze these combined results within the framework of a Tunneling/Resonant/Rayleigh scatterings model, and conclude that the evolution from crystalline to glasslike k(T) is accompanied by an increase both in the effective density of tunnelling states and in the resonant scattering level, while neither one of these contributions can solely account for the observed changes in the full temperature range. This suggests that the most relevant factor which determines crystalline or glasslike behavior is the coupling strength between the guest vibrational modes and the frameworks with different charge carriers.

description: Let $\ell \ne 3$ be a prime. We show that there are only finitely many cyclic number fields $F$ of degree $\ell$ for which the unit equation $$λ+ μ= 1, \qquad λ,~μ\in \mathcal{O}_F^\times$$ has solutions. Our result is effective. For example, we deduce that the only cyclic quintic number field for which the unit equation has solutions is $\mathbb{Q}(ζ_{11})^+$.

description: In this article, we derive a rigorous characterization of the boundary-layer and interior separations in the Taylor-Couette-Poiseuille (TCP) flow. The results obtained provide a rigorous characterization on how, when and where the propagating Taylor vortices (PTV) are generated. In particular, contrary to what is commonly believed, we show that the PTV do not appear after the first dynamical bifurcation, and they appear only when the Taylor number is further increased to cross another critical value so that a structural bifurcation occurs. This structural bifurcation corresponds to the boundary-layer and interior separations of the flow structure in the physical space.

description: Non-Hermitian photonic systems capable of perfectly absorbing incident radiation recently attracted much attention both because fundamentally they correspond to an exotic scattering phenomenon (a real-valued scattering matrix zero) and because their extreme sensitivity holds great technological promise. The sharp reflection dip is a hallmark feature underlying many envisioned applications in precision sensing, secure communication and wave filtering. However, a rigorous link between the underlying scattering anomaly and the sensitivity of the system to a perturbation is still missing. Here, we develop a theoretical description in complex scattering systems which quantitatively explains the shape of the reflection dip. We further demonstrate that coherent perfect absorption (CPA) is associated with a phase singularity and we relate the sign of the diverging time delay to the mismatch between excitation rate and intrinsic decay rate. We confirm our theoretical predictions in experiments based on a three-dimensional chaotic cavity excited by eight channels. Rather than relying on operation frequency and attenuation inside the system to be two free parameters, we achieve "on-demand" CPA at an arbitrary frequency by tweaking the chaotic cavity's scattering properties with programmable meta-atom inclusions. Finally, we theoretically prove and experimentally verify the optimal sensitivity of the CPA condition to minute perturbations of the system.

La disfunzione atriale sinistra causata da depositi fibrillari di amiloide  è associata ad un peggioramento della funzione ventricolare sinistra nei pazienti affetti da amilodosi cardiaca.

description: Il termine amiloidosi indica un insieme eterogeneo di patologie causate dalla deposizione extracellulare di proteine autologhe in forma di fibrille insolubili, che induce la progressiva alterazione architettonica e funzionale degli organi e dei tessuti interessati.
La CMR con gadolinio è in grado di evidenziare anche depositi di amiloide nelle pareti degli atri ,  ai quali però non  è mai stato associato un chiaro significato clinico. In seguito a queste osservazioni ci siamo posti come obiettivo quello di valutare se la deposizione di amiloide nello spessore della parete atriale, riscontrabile mediante CMR potesse avere un ruolo nel grado di dilatazione e di disfunzione atriale in corso di amiloidosi cardiaca e, più in generale, della funzione cardiaca globale. Un gruppo di pazienti, con diagnosi nota di amiloidosi cardiaca (AC), è stato sottoposto a CMR, con utilizzo del gadolinio (CMRGad). In tutti i  pazienti selezionati è stato possibile evidenziare il late enhancement del gadolinio del ventricolo sinistro con il pattern tipico per AC, il cosiddetto zebra-pattern. In alcuni di questi, è stato riscontrato un interessamento anche dello spessore dell'atrio sinistro. Abbiamo deciso, dunque, di raggruppare da un lato i pazienti con evidenza di LGA  atriale (Atria +), dall'altro i restanti  pazienti senza evidenziabile coinvolgimento dell'atrio sinistro (Atria -). I pazienti appartenenti al gruppo Atria + presentavano un peggioramento statisticamente significatico della funzione atriale e della frazione di eiezione ventricolare sinistra rispetto ai pazienti appartenenti al gruppo Atria -.
I nostri dati suggeriscono che Il coinvolgimento dell'atrio potrebbe essere legato o ad un particolare sottotipo di amiloide o ad un diverso stadio di amiloidosi cardiaca. Tali evidenze indicano che la mortalità sia più alta nei pazienti Atria+ rispetto ai soggetti Atria-.

description: We investigate the signature of the photospheric albedo contribution in solar flare hard X-ray spectra, the effect of low energy cutoffs in electron spectra, and the directivity of hard X-ray emission. Using Ramaty High Energy Solar Spectroscopic Imager (RHESSI) flare data we perform a statistical analysis of spatially integrated spectra and positions of solar flares. We demonstrate clear centre-to-limb variation of photon spectral indices in the 15-20 keV energy range and a weaker dependency in the 20-50 keV range which is consistent with photospheric albedo as the cause. The results also suggest that low-energy cutoffs sometimes inferred in mean electron spectra are an artefact of albedo. We also derive the anisotropy (ratio of downward/observer directed photons) of hard X-ray emission in the 15-20 keV range for various heliocentric angles.

Design of composite stiffened panels by new design criteria and progressive failure analysis

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: The objective of this work is the investigation of a new design methodology for the design of composite stiffened panels aiming to reduce the conservatisms of the traditional design and to obtain lighter structures respect to the current ones. In particular the work has evaluated the amount of the weight reduction that can be obtained releasing some traditional limitations and constraints used with the traditional design approach. The new methodology is based on the assumption of the presence of structural health monitoring (SHM) systems, and on the application of the progressive failure analysis (PFA) methodology. With reference to a typical regional aircraft wing box, it has been evaluated the benefit on the weight reduction achievable by redesigning, under compressive load, two stiffened panels representative of the upper skin of the wing box (at wing root and toward the wing tip), releasing some of the conservatisms of the traditional design, because resolved by SHM systems. The identification of the design variables that more affect the weight saving, and definition of the design requirements for the SHM systems, have been performed. The PFA has been applied in order to evaluate the actual residual strength, under compressive load, of impact damaged stiffened panels, considering several discrete damage models with the full mechanical strength properties of the material. The results of these analyses have been compared with those ones of the traditional design; the latter is based on the FPF criteria and on the use of material design allowables degraded because of BVID (Barely Visible Impact Damage) evaluated at coupon level (panel wholly damaged). A simplified design approach, based on the equivalence between the BVID and the hole 6.35 mm (1/4 inch) in diameter, as suggested by industrial guidelines for the preliminary design, has been investigated. All the numerical activities of this study have been supported and verified by correlation with experimental results of CAI (Compression After Impact) tests. In conclusion, in order to assess the real degradation of the load carrying capability at panel level in the presence of BVID, the impact damage induced on CAI coupon has been substituted to an equivalent portion of the skin of a stiffened panel. These analyses have had the scope to evaluate the benefits of a design allowable obtained at panel level rather than at coupon level.

description: The whole slide histopathology images (WSIs) play a critical role in gastric cancer diagnosis. However, due to the large scale of WSIs and various sizes of the abnormal area, how to select informative regions and analyze them are quite challenging during the automatic diagnosis process. The multi-instance learning based on the most discriminative instances can be of great benefit for whole slide gastric image diagnosis. In this paper, we design a recalibrated multi-instance deep learning method (RMDL) to address this challenging problem. We first select the discriminative instances, and then utilize these instances to diagnose diseases based on the proposed RMDL approach. The designed RMDL network is capable of capturing instance-wise dependencies and recalibrating instance features according to the importance coefficient learned from the fused features. Furthermore, we build a large whole-slide gastric histopathology image dataset with detailed pixel-level annotations. Experimental results on the constructed gastric dataset demonstrate the significant improvement on the accuracy of our proposed framework compared with other state-of-the-art multi-instance learning methods. Moreover, our method is general and can be extended to other diagnosis tasks of different cancer types based on WSIs.

Standing Accretion Shocks in the Supernova Core: Effects of Convection and Realistic EOS

Subjects: subject: Astrophysics (astro-ph)

description: We investigated the structure of the spherically symmetric accretion flows through the standing shock wave onto the proto-neutron star in the post-bounce phase of the collapse-driven supernova. We assume that the accretion flow is in a steady state controlled by the neutrino luminosity and mass accretion rate that are kept constant. We obtain solutions of the steady Euler equations for a wide range of neutrino luminosity and mass accretion rate. We employ a realistic EOS and neutrino-heating rates. More importantly, we take into account the effect of convection phenomenologically. For each mass accretion rate, we find the critical neutrino luminosity, above which there exists no steady solution. These critical points are supposed to mark the onset of the shock revival. As the neutrino luminosity increases for a given mass accretion rate, there appears a convectively unstable region at some point before the critical value is reached. We introduce a phenomenological energy flux by convection so that the negative entropy gradient should be canceled out. We find that the convection lowers the critical neutrino luminosity substantially. We also consider the effect of the self-gravity. It is found that the self-gravity is important only when the neutrino luminosity is high. The critical luminosity, however, is little affected if the energy transport by convection is taken into account.

An artifact of hope : the journey of reflexive, participatory research with young women who have faced feelings of depression and disordered eating

description: This practice/thesis documents a search for hope and meaning in the experiences of young women who have faced feelings of depression and disordered eating. This portrait of a process guided by the principles of qualitative, holistic, feminist, reflexive and participatory inquiry reflects the journey of reflexive feminist praxis. My hope is to evoke a sense of the importance and value of feminist theory, the relevance of its application in understanding women's experiences of distress and the vitality of new thought and inquiry arising out of feminist research. This is what I mean by reflexive feminist praxis, where theory inspires action which in turn nourishes new understanding. It is also my wish to demonstrate that this process must include reflection upon the self, the narrator of the story. This is an invitation to reflect upon the meaning of what I have to say in your own story. This journey into meaning-making is therefore dialogic. Feelings of depression and disordered eating can claim the health, joy, hope, energy and passions of us all. This tale is now in your hands, awaiting the 'view from over there'.

description: We study a scale invariant $SU(2)\times U(1)_Y \times U(1)_s$ model which has only dimensionless couplings. The shadow $U(1)_s$ is hidden, and it interacts with the Standard Model (SM) solely through mixing in the scalar sector and kinetic mixing of the U(1) gauge bosons. The gauge symmetries are broken radiatively by the Coleman-Weinberg mechanism. Lifting of the flat direction results in a light shadow Higgs or "scalon", and a heavier scalar which we identify as the SM Higgs boson. The phenomenology of this model is discussed. It is possible that shadow Higgs boson can be discovered in precision $t$-quark studies at the LHC. The conditions that it be a dark matter candidate is also discussed.

description: In the wake of the era of Trump and Brexit, legacies and values of European Enlightenment seem under threat as never before. Cosmopolitanism in particular, generally understood as an Enlightenment virtue, has come to be associated with a sort of rootlessness, and has not, as generally understood, valued local affiliation. For David Goodhart, writing in 2017, this characteristic has resulted in a polarisation between “anywheres” (liberal middle-class cosmopolitans) and “somewheres” (broadly speaking, conservative working-class voters who have strong attachments to their nation and places of origin). An Irish Tory monarchist who sought in his poem The Deserted Village (1770) to defend rural communities from the ravages of economic modernity, Oliver Goldsmith (1728-74) was also in other key works a cosmopolitan commentator who compared countries in order to warn Britain against the dangers of economic liberalism, as he did in The Traveller, or a Prospect of Society (1764). Thus, he could be thought of as a more conservative cosmopolitan than many of his British and French peers; as such his particular enlightenment legacy is his example of a middle ground between the “anywheres” and “somewheres” of Goodhart’s thesis.

description: Understanding the carrier dynamics of nanostructures is the key for development and optimization of novel semiconductor nano-devices. Here, we study the optical properties and carrier dynamics of (InGa)(AsSb)/GaAs/GaP quantum dots (QDs) by means of non-resonant energy and temperature modulated time-resolved photoluminescence. Studying this material system is important in view of the ongoing implementation of such QDs for nano memory devices. Our set of structures contains a single QD layer, QDs overgrown by a GaSb capping layer, and solely a GaAs quantum well, respectively. Theoretical analytical models allow us to discern the common spectral features around the emission energy of 1.8 eV related to GaAs quantum well and GaP substrate. We observe type-I emission from QDs with recombination times between 2 ns and 10 ns, increasing towards lower energies. The distribution suggests the coexistence of momentum direct and indirect QD transitions. Moreover, based on the considerable tunability of the dots depending on Sb incorporation, we suggest their utilization as quantum photonic sources embedded in complementary metal-oxide-semiconductor (CMOS) platforms, since GaP is almost lattice-matched to Si. Finally, our analysis confirms the nature of the pumping power blue-shift of emission originating from the charged-background induced changes of the wavefunction topology.

description: The long standing problem of the relations among the scalar invariants of the Riemann tensor is computationally solved for all 6x10^23 objects with up to 12 derivatives of the metric. This covers cases ranging from products of up to 6 undifferentiated Riemann tensors to cases with up to 10 covariant derivatives of a single Riemann. We extend our computer algebra system Invar to produce within seconds a canonical form for any of those objects in terms of a basis. The process is as follows: (1) an invariant is converted in real time into a canonical form with respect to the permutation symmetries of the Riemann tensor; (2) Invar reads a database of more than 6x10^5 relations and applies those coming from the cyclic symmetry of the Riemann tensor; (3) then applies the relations coming from the Bianchi identity, (4) the relations coming from commutations of covariant derivatives, (5) the dimensionally-dependent identities for dimension 4, and finally (6) simplifies invariants that can be expressed as product of dual invariants. Invar runs on top of the tensor computer algebra systems xTensor (for Mathematica) and Canon (for Maple).

Computational Fluid Dynamics in support to Flight Test Experiments using Optimization Techniques
Creators: name: D'Argenio, Alessandro
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: Flight testing continues to remain an essential step in the development or modification of an aircraft. Modern fixed wing aircrafts, especially mitary jet aircrafts, are highly complex systems that push the edges of aerodynamic, propulsion, and control system technologies. The ever-increasing complexity of the aircrafts presents new challenges to those who are involved in the flight testing of those vehicles.
Over the last 40 years, simulation has played a vital role in increasing the safety and the efficiency of flight testing. Modeling and Simulation (M&S) is a tool to support testing and its use has improved flight test planning, execution and safety. The incredible growth in computational capabilities has created also new possibilities on how M&S can be used to support flight testing.
Even with improved computers, high-fidelity simulations still depend on the ability of the engineering team to create models that accurately represent the aircraft or the environment that they are testing. Simulation is a tool that greatly improves the efficiency and the effectiveness of a flight test program, but it must be used in conjunction and in coordination with the actual testing.
As the aircrafts continue to evolve in complexity, the role of simulation continues to grow. Every major aircraft developer, whether they are commercial or military, depends on the use of simulation to some degree. The application of these simulations to flight testing is an important aspect of the aircraft's development. Many of the technical disciplines involved with the aircraft development make use of simulation.
In flight testing, simulation is especially used to support structures and flutter tests, stores separation tests, as well as total weapon system's effectiveness tests. Simulation in support of flight testing is here to stay, and there is a growing to demand to further increase its use.
The purpose of this thesis is to illustrate how simulation can be effectively used to support flight testing of fixed-wing military aircrafts and what should be considered when developing a simulation that is used to support flight test. In particular, the contribution of M/S in support to store integration and separation activities will be carried out.

description: In order to better understand the minimal ingredients for thermal rectification, we perform a detailed investigation of a simple spin chain, namely, the open XX model with a Lindblad dynamics involving global dissipators. We use a Jordan-Wigner transformation to derive a mathematical formalism to compute the heat currents and other properties of the steady state. We have rigorous results to prove the occurrence of thermal rectification even for slightly asymmetrical chains. Interestingly, we describe cases where the rectification does not decay to zero as we increase the system size, that is, the rectification remains finite in the thermodynamic limit. We also describe some numerical results for more asymmetrical chains. The presence of thermal rectification in this simple model indicates that the phenomenon is of general occurrence in quantum spin systems.

description: The structural properties of static, jammed packings of monodisperse spheres in the vicinity of the jamming transition are investigated using large-scale computer simulations. At small wavenumber $k$, we argue that the anomalous behavior in the static structure factor, $S(k) \sim k$, is consequential of an excess of low-frequency, collective excitations seen in the vibrational spectrum. This anomalous feature becomes more pronounced closest to the jamming transition, such that $S(0) \to 0$ at the transition point. We introduce an appropriate dispersion relation that accounts for these phenomena that leads us to relate these structural features to characteristic length scales associated with the low-frequency vibrational modes of these systems. When the particles are frictional, this anomalous behavior is suppressed providing yet more evidence that jamming transitions of frictional spheres lie at lower packing fractions that that for frictionless spheres. These results suggest that the mechanical properties of jammed and glassy media may therefore be inferred from measurements of both the static and dynamical structure factors.

description: Questo numero monografico ospita una ricerca sul perduto altare di San Giuseppe nel Duomo di Milano, ritenuto uno dei “key monuments” grazie al quale oggi sarebbe forse possibile riportare in squadra tanti aspetti della scultura lombarda che paiono ancora eccessivamente poco chiari. La ricerca è stata condotta attraverso il riesame e l’incremento delle fonti documentarie, evidenziando alcuni snodi problematici relativi allo svolgimento del cantiere, al contesto della committenza e agli aspetti liturgici e devozionali. Le conclusioni non sono sconvolgenti: l’altare, costruito fra il 1472 e il 1499, era e resta perduto, demolito entro il novembre del 1595. Oltre a riconfermare cose che già sappiamo, per esempio che la scultura lombarda è spesso una questione di botteghe, questa ricerca rilancia uno degli interrogativi fondamentali per questo tratto della storia dell’arte: dove e quando nasce quella cifra espressionistica che da Lanzi in poi è riconosciuta come elemento distintivo della scultura lombarda di metà Quattrocento?

This monographic issue is about a research on the lost altar of Saint Joseph in the Cathedral of Milan, considered one of the key monuments thanks to which it would perhaps have been possible to unravel many aspects of Lombard sculpture, those even now too obscure. The research has been conducted through the review and the increase of documentary sources, focusing on some problematic joints relating to the development of the construction, the context of the client, the liturgical and devotional matters. Results are not unexpected: the altar, built between 1472 and 1499, was and remains lost, demolished by November 1595. In addition to reconfirm things we already know – e.g. Lombard sculpture is often a matter of workshops – this research raises one of the fundamental questions related to this segment of art history: when and where does arise that expressionistic style recognized – from Lanzi onwards – as a distinctive element of Lombard sculpture of the mid-15th century?

description: We discuss orientifold projections on superspace effective actions for hypermultiplets. We present a simple and new mechanism that allows one to find the Kahler potential and complex structure for the N=1 theory directly in terms of the parent N=2 theory. As an application, we demonstrate our method for Calabi-Yau orientifold compactifications of type IIB superstrings.

description: The ubiquitin proteasomal system, is an important mediator of protein homeostasis through ubiquitination of substrates, but also coordinates various other functions throughout the cell. Deubiquitinases (DUBs) are essential regulators within this system. They are a specialized class of proteases that can cleave ubiquitin from its substrates and their dysregulation is involved in the development of various diseases. However, the understanding regarding their substrates, cellular localization, their involvement in cellular signaling and structural features remains limited. Despite the enormous therapeutical potential only a few DUB inhibitors are known to date. Therefore, novel tool compounds are of urgent need to enhance the understanding of DUBs in a cellular setting. This thesis describes the discovery, chemical synthesis and biological evaluation of such tool compounds for investigating DUBs in a living environment. To accomplish this, literature-known compounds were resynthesized to introduce alkyne tags to utilize their use as activity-based probes (ABPs) in cell-based systems. An intensive cellular characterization of a dedicated small molecule ABP library targeting DUBs resulted in the discovery of the chemogenomic pair of probes GK13S and GK16S, usable for the selective investigation of the DUB UCHL1 in a living environment. The probes were used to unravel potential substrates and a cellular phenotype after the inhibition of UCHL1. Furthermore, this thesis describes the synthesis and cellular evaluation of PROTAC molecules to study DUBs beyond inhibition. Altogether, this thesis should foster the understanding of DUBs and serve as a blueprint for the synthesis of further probe molecules to study these enzymes.

Exploiting Cross-Dialectal Gold Syntax for Low-Resource Historical Languages: Towards a Generic Parser for Pre-Modern Slavic

description: This paper explores the possibility of improving the performance of specialized parsers for pre-modern Slavic by training them on data from different related varieties. Because of their linguistic heterogeneity, pre-modern Slavic varieties are treated as low-resource historical languages, whereby cross-dialectal treebank data may be exploited to overcome data scarcity and attempt the training of a variety-agnostic parser. Previous experiments on early Slavic dependency parsing are discussed, particularly with regard to their ability to tackle different orthographic, regional and stylistic features. A generic pre-modern Slavic parser and two specialized parsers -- one for East Slavic and one for South Slavic -- are trained using jPTDP (Nguyen & Verspoor 2018), a neural network model for joint part-of-speech (POS) tagging and dependency parsing which had shown promising results on a number of Universal Dependency (UD) treebanks, including Old Church Slavonic (OCS). With these experiments, a new state of the art is obtained for both OCS (83.79\% unlabelled attachment score (UAS) and 78.43\% labelled attachement score (LAS)) and Old East Slavic (OES) (85.7\% UAS and 80.16\% LAS).

description: We calculate the non-zero Boer-Mulders functions of sea quarks inside the proton in a meson-baryon fluctuation model. The results show that the transverse spin effects of sea quarks in an unpolarized nucleon are sizable. Using the obtained antiquark Boer-Mulders functions, we estimate the $\cos 2 ϕ$ asymmetries in the unpolarized $pp$ and $p D$ Drell-Yan processes at FNAL E866/NuSea experiments. The prediction for the $\cos 2 ϕ$ asymmetries in the unpolarized $pp$ Drell-Yan process at the BNL Relativistic Heavy Ion Collider (RHIC) is also given.

description: The influence of a stationary shear flow on the crystallization in a glassy system is studied by means of molecular dynamics simulations and subsequent cluster analysis. The results reveal two opposite effects of the shear flow on the processes of topological ordering in the system. Shear promotes the formation of separated crystallites and suppresses the appearance of the large clusters. The shear-induced ordering proceeds in two stages, where the first stage is related mainly with the growth of crystallites, whereas the second stage is due to an adjustment of the created clusters and a progressive alignment of their lattice directions. The influence of strain and shear rate on the crystallization is also investigated. In particular, we find two plausible phenomenological relations between the shear rate and the characteristic time scale needed for ordering of the amorphous system under shear.

Relazione tra i parametri morfologici e funzionali in pazienti con differente grado di severità glaucomatosa
Creators: name: Minervino, Carlo
Publisher: name: Università degli Studi di Napoli Federico II

description: Abstract

Obiettivo. Valutare la relazione struttura-funzione tra i parametri misurati allo spectral domain optical coherence tomography (SD-OCT) ed al campo visivo nei pazienti con glaucoma ad angolo aperto ed in ciascun gruppo in diverse fasi della malattia.

Metodi. In questo studio prospettico erano inclusi 131 pazienti (66 occhi preperimetrici, 41 occhi con lieve glaucoma, 35 occhi con moderato glaucoma, 40 occhi con severo glaucoma) e 40 occhi normali.
Erano valutati i seguenti parametri: il complesso delle cellule ganglionari (GCC), lo strato delle fibre nervose circumpapillari (RNFL), mean deviation (MD) e pattern standard deviation (PSD).
La relazione tra i parametri in studio era valutata mediante l'analisi di regressione lineare e quadratica mentre le curve ROC erano state utilizzate per determinare il miglior parametro diagnostico nei vari stadi di severità della patologia glaucomatosa.

Risultati. La relazione struttura-funzione era stata maggiormente evidenziata in tutto il gruppo dei pazienti glaucomatosi, GLV, in particolare, mostrava la più alta correlazione con MD e PSD.
Correlazioni significative non sono state trovate nel gruppo dei preperimetrici. Nel gruppo lieve glaucoma il coefficiente di correlazione era più alto tra GLV e PSD mentre i più alti coefficienti di correlazione erano simili nei gruppi moderato e severo glaucoma.
Dei parametri misurati allo SD-OCT inferior and mean GCC thickness rappresentano i miglior parametri diagnostici per discriminare cambiamenti glaucomatosi tra occhi sani e quelli preperimetrici.

Conclusioni. La relazione struttura-funzione mostrava le più alte correlazioni per i parametri del GCC.
Tali parametri sono i primi a subire cambiamenti nello stadio della patologia quando non sono presenti alterazioni al campo visivo e potrebbero essere di aiuto nella diagnosi precoce ed in un valido follow up nella pratica clinica
