description: It is found that the measurement disturbance relation (MDR) determines the strength of quantum correlation and hence is one of the essential facets of the nature of quantum nonlocality. In reverse, the exact form of MDR may be ascertained through measuring the correlation function. To this aim, an optical experimental scheme is proposed. Moreover, by virtue of the correlation function, we find that the quantum entanglement, the quantum non-locality, and the uncertainty principle can be explicitly correlated.

description: ABSTRACT
Zika virus infection is characterized by numerous symptoms including fever, joint pain, conjunctivitis, andneurological complications like the Guillain-Barre syndrome in rare cases. To date, 89 countries and territories have been infected with this virus. There is no specific treatment or approved vaccine available forthe Zika virus. Therefore, there is an urgent need to develop an efficient therapeutic against Zika virus.Previously, it was reported that during infection, viruses or other pathogens downregulate the human miRNAfor better growth. If we increase the level of these downregulated miRNAs, it can inhibit the growth of pathogens or viruses. In the present study, we have used 3'UTR (10367 to 10794) and polyprotein(YP_002790881.1) sequence of Zika virus (NC_012532) for the prediction of human miRNA using the miRNAProtPred webserver. We predicted 193 and 569 unique human miRNAs for the 3'UTR and polyprotein sequences, respectively. 22 human miRNAs were identified as common in both groups. Interestingly, several predicted human miRNAs were reported as downregulated miRNAs during Zika infection or inhibitors of the Zika virus replication/protein expression such as miR-30e-3p. This supports the reliability of the current approach, and the potential of the predicted miRNA to inhibit the growth of Zika virus. However, furthere xperimental validation is required before going to different stages of clinical trials. The current approach will facilitate the development of miRNA-based therapeutics against pathogenic diseases.

description: For over a decade, the application of acoustic radiation force (ARF) has been proposed as a mechanism to increase ultrasonic molecular imaging (MI) sensitivity in vivo. Presented herein is the first noninvasive in vivo validation of ARF-enhanced MI with an unmodified clinical system. First, an in vitro optical-acoustical setup was used to optimize system parameters and ensure sufficient microbubble translation when exposed to ARF. 3D ARF-enhanced MI was then performed on 7 rat fibrosarcoma tumors using microbubbles targeted to αvβ3 and non-targeted microbubbles. Low-amplitude (< 25 kPa) 3D ARF pulse sequences were tested and compared to passive targeting studies in the same animal. Our results demonstrate that a 78% increase in image intensity from targeted microbubbles can be achieved when using ARF relative to the passive targeting studies. Furthermore, ARF did not significantly increase image contrast when applied to non-targeted agents, suggesting that ARF did not increase non-specific adhesion.
Towards a More Affirming Perspective: Contemporary Psychodynamic Practice with Trans* and Gender Non-conforming Individuals

Year: 2013

description: This paper presents new psychodynamic treatment options for trans* (transgender, transsexual, gender-variant, genderqueer, gender fluid, agender, two-spirit) and gender non-conforming (GNC) clients. It addresses the need for these options by highlighting the pervasive heterosexist and transphobic attitudes within the mental health field, including the history of pathologizing trans* identifications and experiences within psychodynamic theory itself. Its focus is on the recent and ongoing transformations of the field as it relates to trans* and gender non-conforming individuals and suggests how contemporary psychodynamic practice might be used to empower trans* and gender non-conforming clients.

description: In this paper, we discuss two simple parametrization methods for calculating Adomian polynomials for several nonlinear operators, which utilize the orthogonality of functions einx, where n is an integer. Some important properties of Adomian polynomials are also discussed and illustrated with examples. These methods require minimum computation, are easy to implement, and are extended to multivariable case also. Examples of different forms of nonlinearity, which includes the one involved in the Navier Stokes equation, is considered. Explicit expression for the n-th order Adomian polynomials are obtained in most of the examples.

description: Phase-change contrast agents (PCCAs), which normally consist of nano/microscale droplets of liquid perfluorocarbons (PFCs) in an encapsulating shell, can be triggered to undergo a phase transition to the highly-echogenic gaseous state upon the input of sufficient acoustic energy. As a result of the subsequent volumetric expansion, a number of unique applications have emerged that are not possible with traditional ultrasound microbubble contrast agents. Although many studies have explored the therapeutic aspects of the PCCA platform, few have examined the potential of PCCAs for molecular imaging purposes. In this study, we demonstrate a PCCA-based platform for molecular imaging using αvβ3-targeted nanoscale PCCAs composed of low-boiling-point PFCs. In-vitro, nanoscale PCCAs adhered to target cells, could be activated and imaged with a clinical ultrasound system and produced a six-fold increase in image contrast compared to non-targeted control PCCAs and a greater than fifty-fold increase over baseline. Data suggest that low-boiling-point nanoscale PCCAs could enable future ultrasound-based molecular imaging techniques in both the vascular and extravascular space.

description: Starting from the collisional Boltzmann equation, we derive for the first time and from first principles the Boltzmann hierarchy for neutrinos including interactions with a scalar particle. Such interactions appear, for example, in majoron-like models of neutrino mass generation. We study two limits of the scalar mass: (i) An extremely massive scalar whose only role is to mediate an effective 4-fermion neutrino-neutrino interaction, and (ii) a massless scalar that can be produced in abundance and thus demands its own Boltzmann hierarchy. In contrast to, e.g., the first-order Boltzmann hierarchy for Thomson-scattering photons, our interacting neutrino/scalar Boltzmann hierarchies contain additional momentum-dependent collision terms arising from a non-negligible energy transfer in the neutrino-neutrino and neutrino-scalar interactions. This necessitates that we track each momentum mode of the phase space distributions individually, even if the particles were massless. Comparing our hierarchy with the commonly used $(c_{\rm eff}^2,c_{\rm vis}^2)$-parameterisation, we find no formal correspondence between the two approaches, which raises the question of whether the latter parameterisation even has an interpretation in terms of particle scattering. Lastly, although we have invoked majoron-like models as a motivation for our study, our treatment is in fact generally applicable to all scenarios in which the neutrino and/or other ultrarelativistic fermions interact with scalar particles.

description: The purpose of this study was to evaluate the reliability of ultrasound measures of muscle cross-sectional area (mCSA) and echo intensity (EI) in overweight subjects. A secondary purpose was to evaluate racial differences in EI, mCSA and body composition. In 33 overweight subjects, mCSA and EI were determined from a panoramic ultrasound scan of the vastus lateralis. Body composition was determined using dual-energy X-ray absorptiometry (DXA). Reliability of mCSA and EI was calculated from the intra-class correlation coefficient (ICC), standard error of the measurement (SEM) and minimal difference (MD). The ICC, SEM and MD for mCSA and EI were 0.87, 2.12, 5.89 and 0.74, 4.58, 12.69, respectively. There were no significant racial differences in body composition (p > 0.05); however, EI was significantly lower for black subjects (p = 0.018). These results suggest ultrasound measures of mCSA and EI are reliable in overweight subjects, and EI may provide additional muscle composition evaluations, beyond DXA measures.

We then propose different viable textures for quarks, where only the Cabibbo mixing arises from the down sector, and extend to the charged leptons while constructing a complementary neutrino structure that leads to viable lepton masses and mixing.

description: Representing patterns as labeled graphs is becoming increasingly common in the broad field of computational intelligence. Accordingly, a wide repertoire of pattern recognition tools, such as classifiers and knowledge discovery procedures, are nowadays available and tested for various datasets of labeled graphs. However, the design of effective learning procedures operating in the space of labeled graphs is still a challenging problem, especially from the computational complexity viewpoint. In this paper, we present a major improvement of a general-purpose classifier for graphs, which is conceived on an interplay between dissimilarity representation, clustering, information-theoretic techniques, and evolutionary optimization algorithms. The improvement focuses on a specific key subroutine devised to compress the input data. We prove different theorems which are fundamental to the setting of the parameters controlling such a compression operation. We demonstrate the effectiveness of the resulting classifier by benchmarking the developed variants on well-known datasets of labeled graphs, considering as distinct performance indicators the classification accuracy, computing time, and parsimony in terms of structural complexity of the synthesized classification models. The results show state-of-the-art standards in terms of test set accuracy and a considerable speed-up for what concerns the computing time.

description: We introduce the notion of a Thom class of a current and define the localized intersection of currents. In particular we consider the situation where we have a smooth map of manifolds and study localized intersections of the source manifold and currents on the target manifold. We then obtain a residue theorem on the source manifold and give explicit formulas for the residues in some cases. These are applied to the problem of coincidence points of two maps. We define the global and local coincidence homology classes and indices. A representation of the Thom class of the graph as a Cech-de~Rham cocycle immediately gives us an explicit expression of the index at an isolated coincidence point, which in turn gives explicit coincidence classes in some non-isolated components. Combining these, we have a general coincidence point theorem including the one by S. Lefschetz.
Construction of bosonic symmetry-protected-trivial states and their topological invariants via $G\times SO(\infty)$ non-linear $σ$-models

description: It has been shown that the L-type bosonic symmetry-protected-trivial (SPT) phases with pure gauge anomalous boundary can all be realized via non-linear $σ$-models (NL$σ$Ms) of the symmetry group $G$ with various topological terms. Those SPT phases (called the pure SPT phases) can be classified by group cohomology ${\cal H}^d(G,\mathbb{R}/\mathbb{Z})$. But there are also SPT phases with mixed gauge-gravity anomalous boundary (which will be called the mixed SPT phases). Some of the mixed SPT states were also referred as the beyond-group-cohomology SPT states. In this paper, we show that those beyond-group-cohomology SPT states are actually within another type of group cohomology classification. More precisely, we show that both the pure and the mixed SPT phases can be realized by $G\times SO(\infty)$ NL$σ$Ms with various topological terms. Through the group cohomology ${\cal H}^d[G\times SO(\infty),\mathbb{R}/\mathbb{Z}]$, we find that the set of our constructed L-type SPT phases in $d$-dimensional space-time are classified by $ E^d(G)\rtimes \oplus_{k=1}^{d-1} {\cal H}^k(G,\text{iTO}_L^{d-k})\oplus {\cal H}^d(G,\mathbb{R}/\mathbb{Z}) $ where $G$ may contain time-reversal. Here $\text{iTO}_L^d$ is the set of the L-type topologically-ordered phases in $d$-dimensional space-time that have no topological excitations, and one has $\text{iTO}_L^1=\text{iTO}_L^2=\text{iTO}_L^4=\text{iTO}_L^6=0$, $\text{iTO}_L^3=\mathbb{Z}$, $\text{iTO}_L^5=\mathbb{Z}_2$, $\text{iTO}_L^7=2\mathbb{Z}$. Our construction also gives us the topological invariants that fully characterize the corresponding SPT and iTO phases. Through several examples, we show how can the universal physical properties of SPT phases be obtained from those topological invariants.

description: Many studies have explored phase-change contrast agents (PCCAs) that can be vaporized by an ultrasonic pulse to form microbubbles for ultrasound imaging and therapy. However, few investigations have been published demonstrating the utility and characteristics of PCCAs as contrast agents in vivo. In this study, we examine the properties of low boiling point nanoscale PCCAs evaluated in vivo, and compare data to conventional microbubbles with respect to contrast generation and circulation properties. In order to do this, we develop a custom pulse sequence to vaporize and image PCCAs using the Verasonics research platform and a clinical array transducer. Results show that droplets can produce similar contrast enhancement to microbubbles (7.29 to 18.24 dB over baseline, depending on formulation), and can be designed to circulate for as much as 3.3 times longer than microbubbles. This study also demonstrates for the first time the ability to capture contrast wash-out kinetics of the target organ as a measure of vascular perfusion.

description: The longest common substring with $k$-mismatches problem is to find, given two strings $S_1$ and $S_2$, a longest substring $A_1$ of $S_1$ and $A_2$ of $S_2$ such that the Hamming distance between $A_1$ and $A_2$ is $\le k$. We introduce a practical $O(nm)$ time and $O(1)$ space solution for this problem, where $n$ and $m$ are the lengths of $S_1$ and $S_2$, respectively. This algorithm can also be used to compute the matching statistics with $k$-mismatches of $S_1$ and $S_2$ in $O(nm)$ time and $O(m)$ space. Moreover, we also present a theoretical solution for the $k = 1$ case which runs in $O(n \log m)$ time, assuming $m\le n$, and uses $O(m)$ space, improving over the existing $O(nm)$ time and $O(m)$ space bound of Babenko and Starikovskaya.

description: We calculate for the first time the form factors of the semi-leptonic decays of the $D_s$ meson to $η$ and $η^\prime$ using lattice techniques. As a by-product of the calculation we obtain the masses and leading distribution amplitudes of the $η$ and $η^\prime$ mesons. We use $N_f=2+1$ non-perturbatively improved clover fermions on configurations with a lattice spacing $a\sim 0.075$ fm. We are able to obtain clear signals for relevant matrix elements, using several noise reduction techniques, both for the connected and disconnected contributions. This includes a new method for reducing the variance of pseudoscalar disconnected two-point functions. At zero momentum transfer, we obtain for the scalar form factors, $|f_0^{D_s\to η}|=0.564(11)$ and $|f_0^{D_s\to η'}|=0.437(18)$ at $M_π\approx 470\, {\rm MeV}$, as well as $|f_0^{D_s\to η}|=0.542(13)$ and $|f_0^{D_s\to η'}|=0.404(25)$ at $M_π\approx 370\, {\rm MeV}$, where the errors are statistical only.

description: A major roadblock for large-scale photonic quantum technologies is the lack of practical reliable certification tools. We introduce an experimentally friendly - yet mathematically rigorous - certification test for experimental preparations of arbitrary m-mode pure Gaussian states, pure non-Gaussian states generated by linear-optical circuits with n-boson Fock-basis states as inputs, and states of these two classes subsequently post-selected with local measurements on ancillary modes. The protocol is efficient in m and the inverse post-selection success probability for all Gaussian states and all mentioned non-Gaussian states with constant n. We follow the mindset of an untrusted prover, who prepares the state, and a skeptic certifier, with classical computing and single-mode homodyne-detection capabilities only. No assumptions are made on the type of noise or capabilities of the prover. Our technique exploits an extremality-based fidelity bound whose estimation relies on non-Gaussian state nullifiers, which we introduce on the way as a byproduct result. The certification of many-mode photonic networks, as those used for photonic quantum simulations, boson samplers, and quantum metrology, is now within reach.

title: Elterliches Selbstvertrauen und Emotionsregulation als Mediatoren im Zusammenhang zwischen psychischer Belastung der Eltern und frühkindlichen Regulationsproblemen
Creators: name: Schuh, Sarah
Year: 2022

description: Die Regulationsfähigkeit des Säuglings stellt einen wichtigen Meilenstein in der frühen Kindheit dar. Als Risikofaktoren für frühkindliche Regulationsprobleme werden mehrere Variablen diskutiert. Ziel der vorliegenden Studie war es, den Zusammenhang zwischen der elterlichen psychischen Belastung und frühkindlichen Regulationsproblemen aufzuklären und zu untersuchen, inwiefern das elterliche Selbstvertrauen und die elterliche Emotionsregulation in diesen Zusammenhang hineinspielen. Dazu wurden 112 Eltern von Säuglingen im Alter von 3 bis 12 Monaten rekrutiert. Die querschnittliche Datenerhebung erfolgte mittels standardisierter Selbstbeurteilungsfragebögen: psychische Belastung (DASS-21), elterliches Selbstvertrauen (MSCS), elterliche Emotionsregulation (ERQ) und frühkindliche Regulationsprobleme (SFS). Als Resultat zeigte sich, dass das elterliche Selbstvertrauen den Zusammenhang zwischen elterlicher psychischer Belastung und frühkindlichen Regulationsproblemen signifikant mediierte. Die Emotionsregulationsstrategie Unterdrückung fungiert hingegen nicht als Mediator in diesem Zusammenhang. Diese Studie hebt die Relevanz der Implementierung der Erfassung und Stärkung des elterlichen Selbstvertrauens in präventiven Therapieansätzen hervor. Das elterliche Selbstvertrauen könnte eine Schlüsselrolle spielen und letztlich zu einer gelungen Eltern-Kind-Interaktion beitragen.
description: The infant's ability to regulate represents an important milestone in early childhood. Several variables are discussed as risk factors for early childhood regulatory problems. The aim of the present study was to elucidate the association of parental psychological distress and early childhood regulatory problems and to examine the extent to which parental self-confidence and parental emotion regulation are important for this relationship. For this purpose, 112 parents of infants aged 3 to 12 months were recruited. Cross-sectional data collection was conducted using standardized self-report questionnaires: psychological distress (DASS-21), parental selfconfidence (MSCS), parental emotion regulation (ERQ) and early childhood regulation problems (SFS). As a result, parental self-confidence was found to significantly mediate the association of parental psychological distress and early childhood regulation problems. In contrast, the emotion regulation strategy suppression does not act as a mediator in this context. This study highlights the relevance of implementing the assessment and enhancement of parental self-confidence in preventive therapy approaches. Parental self-confidence could play a key role and ultimately contribute to successful parent-child interactions.

description: In the context of global/goal-oriented error estimation applied to computational mechanics, the need to obtain reliable and guaranteed bounds on the discretization error has motivated the use of residual error estimators. These estimators require the construction of admissible stress fields verifying the equilibrium exactly. This article focuses on a recent method, based on a flux-equilibration procedure and called the element equilibration + star-patch technique (EESPT), that provides for such stress fields. The standard version relies on a strong prolongation condition in order to calculate equilibrated tractions along finite element boundaries. Here, we propose an enhanced version, which is based on a weak prolongation condition resulting in a local minimization of the complementary energy and leads to optimal tractions in selected regions. Geometric and error estimate criteria are introduced to select the relevant zones for optimizing the tractions. We demonstrate how this optimization procedure is important and relevant to produce sharper estimators at affordable computational cost, especially when the error estimate criterion is used. Two- and three-dimensional numerical experiments demonstrate the efficiency of the improved technique.

description: Ischemic stroke from thromboembolic sources is linked to carotid artery atherosclerotic disease with a trend toward medical management in asymptomatic patients. Extent of disease is currently diagnosed by noninvasive imaging techniques that measure luminal stenosis, but it has been suggested that a better biomarker for determining risk of future thromboembolic events is plaque morphology and composition. Specifically, plaques that are composed of mechanically-soft lipid/necrotic regions covered by thin fibrous caps are the most vulnerable to rupture. An ultrasound technique that noninvasively interrogates the mechanical properties of soft tissue, called acoustic radiation force impulse (ARFI) imaging, has been developed as a new modality for atherosclerotic plaque characterization using phantoms and atherosclerotic pigs, but the technique has yet to be validated in vivo in humans. In this preliminary study, in vivo ARFI imaging is presented in a case-study format from four patients undergoing clinically-indicated carotid endarterectomy and compared to histology. In two type Va plaques, characterized by lipid/necrotic cores covered by fibrous caps, mean ARFI displacements in focal regions were high relative to the surrounding plaque material, suggesting soft features covered by stiffer layers within the plaques. In two type Vb plaques, characterized by heavy calcification, mean ARFI peak displacements were low relative to the surrounding plaque and arterial wall, suggesting stiff tissue. This pilot study demonstrates the feasibility and challenges of transcutaneous ARFI for characterizing the material and structural composition of carotid atherosclerotic plaques via mechanical properties, in humans, in vivo.

We developed a numerical code for solution of inverse problem for cosmic-ray transport equations that allows the determination of average source spectra of different nuclei from the cosmic ray spectra observed at the Earth. Employing this approach, the injection spectra of protons and Iron nuclei in extragalactic sources are found assuming that only these species are accelerated at the source. The data from the Auger experiment and the combined data from the Telescope Array + HiRes experiments are used to illustrate the method.

description: Acoustic angiography imaging of microbubble contrast agents utilizes the superharmonic energy produced from excited microbubbles, and enables high-contrast, high-resolution imaging. However, the exact mechanism by which broadband harmonic energy is produced is not fully understood. In order to elucidate the role of microbubble shell fragmentation in superharmonic signal production, simultaneous optical and acoustic measurements were performed on individual microbubbles at transmit frequencies from 1.75 to 3.75 MHz and pressures near the shell fragmentation threshold for microbubbles of varying diameter. High-amplitude, broadband superharmonic signals were produced with shell fragmentation, while weaker signals (approximately 25% of peak amplitude) were observed in the presence of shrinking bubbles. Furthermore, when imaging populations of stationary microbubbles with a dual-frequency ultrasound imaging system, a sharper decline in image intensity with respect to frame number was observed for 1 μm bubbles than for 4 μm bubbles. Finally, in a study of two rodents, increasing frame rate from 4 to 7 Hz resulted in a decrease in mean steady-state image intensity of 27% at 1000 kPa and 29% at 1300 kPa. While the existence of superharmonic signals when bubbles shrink has the potential to prolong the imaging efficacy of microbubbles, parameters such as frame rate and peak pressure must be balanced with expected re-perfusion rate in order to maintain adequate contrast during in vivo imaging.

description: This short note amends Proposition 2.5 of the named article, which states that a full coaction of a locally compact group on a C*-algebra is nondegenerate if and only if its normalization is. The proof given there of the reverse implication is incorrect and, unfortunately, we have been unable to find a correct proof. Instead, we summarize the current state of our knowledge of the relationships between nondegeneracy of normal, reduced, and generic C*-coactions.

description: The recent design of ultra-broadband, multi-frequency ultrasound transducers has enabled high sensitivity, high-resolution contrast imaging, with very efficient suppression of tissue background using a technique called acoustic angiography. Here we perform the first application of acoustic angiography to evolving tumors in mice predisposed to develop mammary carcinoma, with the intent of visualizing and quantifying angiogenesis progression associated with tumor growth. Metrics compared include vascular density and two measures of vessel tortuosity quantified from segmentations of vessels traversing and surrounding 24 tumors and abdominal vessels from control mice. Quantitative morphological analysis of tumor vessels demonstrated significantly increased vascular tortuosity abnormalities associated with tumor growth with the distance metric elevated approximately 14% and the sum of angles metric increased 60% in tumor vessels versus controls. Future applications of this imaging approach may provide clinicians a new tool in tumor detection, differentiation, or evaluation, though with limited depth of penetration using the current configuration.

description: Diagnosis of primary ciliary dyskinesia (PCD) by identification of dynein arm loss in transmission electron microscopy (TEM) images can be confounded by high background noise due to random electron-dense material within the ciliary matrix, leading to diagnostic uncertainty even for experienced morphologists. We developed a novel image analysis tool to average the axonemal peripheral microtubular doublets, thereby increasing microtubular signal and reducing random background noise. In a randomized, double-blinded study that compared two experienced morphologists and three different diagnostic approaches, we found that use of this tool led to improvement in diagnostic TEM test performance.

description: In this work, we explore a mechanism for abelian gauge field localization on thick branes based on a five-dimensional Stueckelberg-like action. A normalizable zero mode is found through the identification of a suitable coupling function between the brane and the gauge field. The same mechanism is studied for the localization of the abelian Kalb--Ramond field.

ON NEUTRON STARS'CRUST BREAKING AND GRAVITATIONAL WAVES EMISSION

description: Many different astrophysical events related to pulsars are taught to be due to starquakes, that could be caused by various possible loadings acting on the crust. However, at the present time, there is still a lack of theoretical well based modelling for most of these loadings and, therefore, we have only a very rough knowledge of the physics of neutron stars? crust response. This PhD work wants to be a first development of a quite realistic calculation of the effects of chosen loadings, being that the forces due to uniform rotation, differential rotation or pinning, on the crust of pulsars. A Newtonian model, already used in Geophysics, has been adapted to the very different physical conditions of neutron stars? physics and used to describe self-gravitating neutron stars, both in the incompressible and compressible scenario, subjected to different kinds of loadings. In particular, the deformations due to uniform rotation, differential rotation and slack pinning are studied. It is found that the response of the star is very sensitive to the adiabatic index value, while it is weakly influenced by the stellar mass. In all the cases, the strain developed between two glitches is found to be insufficient to break the crust, a result that challenges the standard picture of pulsar glitches based on crustquakes. Finally, attention is focused on accreting neutron stars in low-mass X-ray binaries and millisecond pulsars. The scenario is the following: the star spins up due to the accretion of matter thus building up stress; the mass quadrupole moment associated with crustal failures leads to the emission of gravitational waves which, in turn, spins down the star until equilibrium. The equilibrium frequency calculated is found compatible with observations. It is also argued that these gravitational waves could be potentially detected by the LIGO-Virgo interferometers in the near future.
CONDIZIONI GENERALI DI CONTRATTO E TUTELA DELLA CONCORRENZA

description: The present thesis seeks to inquire the possibility to operate a control on the content of standard contracts through the application of competition law: namely, it aims to identify in which cases an enterprise violates competition law by adopting standard terms and employing them in its contractual relationships; furthermore, it wishes to analyze which remedies are available to the enterprise?s contractual counterparties. The enquiry is particularly relevant in the current socio-economical context, in which new market powers are rising and seem able to defy traditional antitrust law tenets. The reference is to the so-called ?Big Tech companies?, i.e. firms (such as Facebook, Google or Amazon) which, by offering apparently free services (which are actually paid for by the exploitation of users? personal data), have hitherto managed to escape antitrust scrutiny. However, some recent investigations have reversed the trend and have found these firms guilty of infringing antitrust law by adopting terms and conditions particularly prejudicial to the user (especially with regards to protection of its privacy). From another point of view, the ?antitrust control? on standard contracts may allow to identify the remedy available to the prejudiced party within contractual relationships where, despite the fact that both parties are technically ?professional?, a significant imbalance of bargaining power exists, so that the weak party is forced to enter into a detrimental contract. In order to answer these questions, the thesis analyses the debate between scholars regarding the feasibility of a control of substance of standard contracts, whereas the Italian Civil Code only provides for a formal control; moreover, it examines the different doctrinal opinions on the matter of the relation between antitrust prohibitions and the contracts that the dominant enterprise stipulates with professionals and consumers alike.
Modified natural inflation: A small single field model with a large tensor to scalar ratio

description: In this paper we explored in detail a phenomenological model of modified single field natural inflation in light of recent cosmological experiments, BICEP2. Our main goal is to construct an inflationary model which not only predicts the important cosmological quantities such as $(n_s, r)$ compatible with experimental observation, but also is consistent with the low energy effective theory framework. Therefore, all the fundamental scale apart from $M_p$ and quantities of our interest should be within the sub-Planckian region. In order to achieve our goal we modify the usual single field natural inflationary model by a specific form of higher derivative kinetic term called kinetic gravity braiding (KGB). One of our guiding principles to construct such a model is the constant shift symmetry of the axion. We have chosen the form of the KGB term in such a way that it predicts the required value of $n_s\simeq 0.96$ and a large tensor to scalar ratio $r> 0.1$. Importantly for a wide range of parameter space our model has sub-Planckian axion decay constant $f$ and the scale of inflation $Λ$. However, the reheating after the end of inflation limits the value of $f$ so that we are unable to get $f$ to be significantly lower than $M_p$. Furthermore, we find sub-Planckian field excursion for the axion field $Δϕ\simeq f$ for the sufficient number of e-folding ${\cal N} \gtrsim 50 $. We also discussed in detail about the natural preheating mechanism in our model based on the recently proposed Chern-Simon coupling. We found this gravity mediated preheating is very difficult to achieve in our model. With our general analytic argument, we also would like to emphasize that Chern-Simons mediated preheating is very unlikely to happen in any slow roll inflationary model.

description: Over 65,000 Americans are diagnosed with kidney cancer each year and nearly 13,000 die of this disease. Kidney cancer is not a single disease, it is made up of a number of different types of cancer, each with a different histology, a different clinical course, responding differently to therapy and caused by a different gene. Study of the thirteen genes that are known to cause kidney cancer has led to the understanding that kidney cancer is a metabolic disease. Recent discoveries of chromatin remodeling/histone modifying genes, such as PBRM1 and SETD2, has opened up new areas of intense interest in the study of the fundamental genetic basis of kidney cancer. New approaches to immunotherapy with agents such as the CTLA4 inhibitor, ipilumumab, have opened up promising new directions for clinical trials. A number of new agents targeting of VEGF receptor signaling and the mTOR pathways as well as novel approaches targeting HIF2 will hopefully provide the foundation for the development of effective forms of therapy for this disease.
