Surface runoff revitalization policy in the context of climate change in the Senegal River watershed
Creators: name: Abdoulaye FATY
Publisher: name: Zenodo
Year: 2024

description: In the Senegal River watershed, hydroelectric infrastructure and land use have profoundly altered the hydrosystem, resulting in environmental imbalance. The aim of this study is to propose policy options for revitalizing surface runoff in the Senegal River watershed, using remote sensing, geographic information systems and spatio-temporal modelling tools, coupled with climate change indicators. Several types of data were used.   The Land Change Modeler (LCM) model was used to simulate the data and make projections up to 2030 of land use in the Senegal River basin. In this study, the author chose three scenarios Business-As-Usual (BAU), Rapid Economic Growth (REC) or maximalist scenario and Coordinated Environmental Sustainability (CED) or medium scenario.   The results show that the CED scenario offers hope that the restoration and preservation of plant resources is still possible to ensure the revitalization of surface flows in the Senegal River basin.

description: Graph-level anomaly detection (GAD) describes the problem of detecting graphs that are abnormal in their structure and/or the features of their nodes, as compared to other graphs. One of the challenges in GAD is to devise graph representations that enable the detection of both locally- and globally-anomalous graphs, i.e., graphs that are abnormal in their fine-grained (node-level) or holistic (graph-level) properties, respectively. To tackle this challenge we introduce a novel deep anomaly detection approach for GAD that learns rich global and local normal pattern information by joint random distillation of graph and node representations. The random distillation is achieved by training one GNN to predict another GNN with randomly initialized network weights. Extensive experiments on 16 real-world graph datasets from diverse domains show that our model significantly outperforms seven state-of-the-art models.

Evolving Fertility Goals and Behaviors in Current U.S. Childbearing Cohorts
Creators: name: Hayford, Sarah R
name: Guzzo, Karen Benjamin
Publisher: name: Wiley
Year: 2023

description:
In the post-Recession era, U.S. fertility rates have continued to fall. It is unclear if these declines are driven by shifts in fertility goals or growing difficulty in achieving goals. In this paper, we construct synthetic cohorts of men and women to examine both cross-cohort and within-cohort changes in fertility goals using multiple cycles of the National Survey of Family Growth. Although more recent cohorts exhibit lower achieved fertility at younger ages than earlier cohorts at the same age, intended parity remains around two children, and intentions to remain childless rarely exceed 15%. There is weak evidence of a growing fertility gap in the early 30s, suggesting more recent cohorts will need considerable childbearing in the 30s and early 40s to 'catch up' to earlier goals, yet low-parity women in their early 40s are decreasingly likely to have unfulfilled fertility desires or intentions to have children. Low-parity men in their early 40s, though, are increasingly likely to intend children. Declines in U.S. fertility thus seem to be largely driven not by changes in early-life fertility goals so much as either a decreasing likelihood of achieving earlier goals or, perhaps, shifts in the preferred timing of fertility that depress period measures.
The decree of Kleinias
Creators: name: Mark, Gwyneth Anita
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is to study the decree of Kleinias, with a view to determining its purpose and date, using epigraphic criteria and internal evidence. The arguments from historical context are merely summarized in Chapter 1, Introduction. Chapter 2 determines the readings. Chapter 3 discusses the evidence of the letter-forms and characterizes the mason. The conclusion of this chapter is that a date in the 430s is best. Chapter 4 discusses the evidence of spelling, which is of no help for dating, and formulae, which suggest a date in the late 440s or 430s. Chapter 5 gives the restoration of the text, and commentary. From internal evidence discussed in this chapter, a date after 453 and before 426 is necessary. The decree seems to be concerned not with recalcitrant subject cities, but only with dishonesty and poor bookkeeping. Chapter 6 briefly restates the evidence found in the previous chapters.

description:
BACKGROUND: Transgender and non-binary (trans*) individuals face disproportionately high rates of sexual violence yet experience discrimination at rape crisis centers (RCCs). Sexual assault nurse examiners (SANEs) who receive targeted education are better equipped to care for the trans* community. AIMS: This quality improvement project aimed to increase SANEs' self-perceived competence in caring for trans* assault survivors. The secondary purpose was to promote a trans*-inclusive environment at an RCC based on an environmental assessment. METHODS: The project involved creating and implementing a virtual continuing education course on providing gender-affirming and trans*-specific care for sexual assault survivors and an environmental evaluation at an RCC. A questionnaire measured SANEs' perceived competency pretraining and posttraining, and paired t tests were conducted to examine the change in competencies. A modified assessment tool was used to evaluate the RCC's capacity for addressing trans* survivors needs. RESULTS: The training increased self-perceived competency in all four components measured ( p < 0.005). More than one third of participants (36.4%, n = 22) indicated having no expertise, and 63.7% reported having some expertise in caring for trans* clients. Two thirds (66.7%) had prior trans*-specific training; however, only 18.2% received trans*-specific content in their SANE training. Most strongly agreed (68.2%) they would benefit from additional training. The organizational assessment identified key areas for improvement. CONCLUSIONS: Trans*-specific training can significantly impact SANEs' self-perceived competency in caring for trans* assault survivors and is feasible and acceptable. This training could have a global impact on SANEs if disseminated more widely, particularly with inclusion in SANE curriculum guidelines.

description: Broken symmetries play a fundamental role in superconductivity and influence many of its properties in a profound way. Understanding these symmetry breaking states is essential to elucidate the various exotic quantum behaviors in non-trivial superconductors. Here, we report an experimental observation of spontaneous rotational symmetry breaking of superconductivity at the heterointerface of amorphous (a)-YAlO$_3$/KTaO$_3$(111) with a superconducting transition temperature of 1.86 K. Both the magnetoresistance and superconducting critical field in an in-plane field manifest striking twofold symmetric oscillations deep inside the superconducting state, whereas the anisotropy vanishes in the normal state, demonstrating that it is an intrinsic property of the superconducting phase. We attribute this behavior to the mixed-parity superconducting state, which is an admixture of \emph{s}-wave and \emph{p}-wave pairing components induced by strong spin-orbit coupling inherent to inversion symmetry breaking at the heterointerface of a-YAlO$_3$/KTaO$_3$. Our work suggests an unconventional nature of the underlying pairing interaction in the KTaO$_3$ heterointerface superconductors, and brings a new broad of perspective on understanding non-trivial superconducting properties at the artificial heterointerfaces.

description: The magnetic properties of transition-like metals are discussed within the single site approximation, which is a picture to take into account electron correlations. The metal is described by two hybridized bands one of which includes Coulomb correlation. The presented results indicate that ferromagnetism arises for adequate values of hybridization (V), correlation (U) and occupation number($n_σ$). Some similarities with Dynamical Mean-Field Theory (DMFT) are indicated.

Trajectory and smooth attractors for Cahn-Hilliard equations with inertial term

description: The paper is devoted to a modification of the classical Cahn-Hilliard equation proposed by some physicists. This modification is obtained by adding the second time derivative of the order parameter multiplied by an inertial coefficient which is usually small in comparison to the other physical constants. The main feature of this equation is the fact that even a globally bounded nonlinearity is "supercritical" in the case of two and three space dimensions. Thus the standard methods used for studying semilinear hyperbolic equations are not very effective in the present case. Nevertheless, we have recently proven the global existence and dissipativity of strong solutions in the 2D case (with a cubic controlled growth nonlinearity) and for the 3D case with small inertial coefficient and arbitrary growth rate of the nonlinearity. The present contribution studies the long-time behavior of rather weak (energy) solutions of that equation and it is a natural complement of the results of our previous papers. Namely, we prove here that the attractors for energy and strong solutions coincide for both the cases mentioned above. Thus, the energy solutions are asymptotically smooth. In addition, we show that the non-smooth part of any energy solution decays exponentially in time and deduce that the (smooth) exponential attractor for the strong solutions constructed previously is simultaneously the exponential attractor for the energy solutions as well.
Archetipo versus anarchetipo
Creators: name: Braga, Corin
Publisher: name: Firenze University Press
Year: 2013
Subjects: archetype; anarchetype; structure; anarchy; deconstruction

description: In this paper, I try to coin a new concept: the anarchetype. The anarchetype is, from a formal point of view, a dissolute or exploded archetype. Generally speaking, archetypal literary works have a structure, a logos, a homogenous pattern which gives them a global meaning. This pattern could be inherited from the cultural tradition (O’Neill revisiting the Electra legend, James Joyce rewriting the Odyssey, etc.), or generated by the genre during its evolution (the Bildungsroman, etc.). Symmetrically, anarchetypal works or bodies of texts appear as anarchical and chaotic. They do not accept a central organizing meaning, they evolve on different contradictory levels. Using a cosmological metaphor, I would compare the archetype with a solar system, in which the planets harmoniously move around the central sun, while an anarchetype is similar to a galactic cloud of dust before its accretion in a solar system or resulting from the explosion of a supernova. The complementary terms archetype/anarchetype partially recall Deleuze’s opposition between “root” and “rhizomes”.

description: Adiabatic techniques using multi-level systems have recently been generalised from the optical case to settings in atom optics, solid state and even classical electrodynamics. The most well known example of these is the so called STIRAP process, which allows transfer of a particle between different states with large fidelity. Here we generalise and examine this process for an atomic centre-of-mass state with a non-trivial phase distribution and show that even though dark state dynamics can be achieved for the atomic density, the phase dynamics will still have to be considered as a dynamical process. In particular we show that the combination of adiabatic and non-adiabatic behaviour can be used to engineer phase superposition states.

description: We derive a renormalization method to calculate the spectral dimension $\bar{d}$ of deterministic self-similar networks with arbitrary base units and branching constants. The generality of the method allows the affect of a multitude of microstructural details to be quantitatively investigated. In addition to providing new models for physical networks, the results allow precise tests of theories of diffusive transport. For example, the properties of a class of non-recurrent trees ($\bar{d}>2$) with asymmetric elements and branching violate the Alexander Orbach scaling law.
Collective excitations in three-band superconductors

description: We investigate equilibrium states, magnetic response and the normal oscillations of internal degrees of freedom (Higgs modes and Goldstone modes) of three-band superconductors accounting the terms of both internal proximity effect and the ``drag'' effect (intergradient interaction) in the Lagrangian. Both the Goldstone mode and the Higgs mode are split into three branches each: common mode oscillations and two modes of anti-phase oscillations, which are analogous to the Leggett mode in two-band superconductors. It is demonstrated that the second and third branches are nonphysical, and they can be removed by special choice of coefficients at the ``drag'' terms in Lagrangian. As a result, three-band superconductors are characterized by only single coherence length. Spectrum of the common mode Higgs oscillations has been obtained. The magnetic penetration depth is determined with densities of superconducting electrons in each band, although the drag terms renormalize the carrier masses.

Cabotegravir long-acting injectable HIV pre-exposure prophylaxis (LA PrEP) is efficacious, with a good safety profile, and was approved by the US Food and Drug Administration in December 2021. Understanding variations in potential user preferences for LA PrEP may inform implementation and subsequently improve uptake and community-level effectiveness. HIV-negative, sexually active men who have sex with men (MSM) aged ≥15 years were recruited online for the 2019 American Men's Internet Survey, before LA PrEP approval. Respondents completed a discrete-choice experiment (DCE) with hypothetical LA PrEP attributes (out-of-pocket cost, perceived side effects, injection frequency, perceived stigma, service location). Latent class analysis segmented respondents into groups based on their preferences for the attributes presented, and relative importance of preference weights and willingness-to-pay were calculated. While the majority had never used daily oral PrEP, 73% of the 2489 respondents were very or somewhat likely to use LA PrEP. Three latent classes were identified from 2241 respondents in the DCE. The "side effects-averse" class was the largest group (64% of respondents) and placed 61% relative importance on side effects. The "ambivalent" class (20% of respondents) placed higher importance on stigma (17% of relative importance) than other classes. The "cost-conscious" class (16% of respondents) placed higher relative importance (62%) on cost compared with other attributes and classes. Perceived side effects were an important hypothetical barrier for LA PrEP uptake among a large proportion of potential MSM users. Minimizing out-of-pocket costs is likely to increase uptake and may be important to equitable access. Tailored communication strategies are recommended for the different groups of potential LA PrEP users.
Improper Narratives: Egyptian Personal Blogs and the Arabic Notion of Adab

Subjects: Egypt; blogs; literature; literariness; adab

description: In recent years several international scholars have started to move beyond the social and political effect of blogging to define blogs in terms of literary writing (See Fitzpatrick, 2006; Himmer 2004; Van Dijk, 2004). Also in the Arab world, the fact that several blogs have been turned into books and have had considerable success, has provoked a debate over the literary status of blogs: while some critics hail them as a new literary experiment, others claim that they do not have the legitimacy to be included in the category of adab (literature). This has perhaps to do with the fact that in the Arab world (as elsewhere) printed books enjoy more prestige; but also with the fact that the Arab notion of adab is gradually coinciding, though still differing from the European notion of “literature”, and this defines the boundaries of the literary field. In other words, to claim that a work is “literary” because it has aspects of “literariness”, does not wholly correspond to saying that it is adabī, i.e. “literary” for Arab critics. In this article I will discuss aspects of literariness and adab-icity by means of an analysis of the blog al-Kanabah al-Ḥamrā (The Red Sofa), written by the Egyptian Bilāl Ḥusnī. The blog has been reviewed in several Egyptian newspapers and literary websites as “an interactive fiction” or a “adabī/literary and visual blog”. However, its style, contents and materiality challenge both our notion of “literature” and the Arab concept of adab.

Black Towns and (Legal) Marronage
Creators: name: Purifoy, Danielle
Publisher: name: Taylor & Francis
Year: 2023

description:
Since the U.S. antebellum era, enslaved and free Black people established places of their own to defend against White supremacist violence. These communities often formed on perilous landscapes, spaces considered undesirable, inaccessible, and uninhabitable by White planter classes. This form of fugitivity persisted after the postbellum era, and recurs in various forms in the present day, commonly through the formation of legally sanctioned Black communities. The rationales for contemporary incorporation of Black towns share similarities with their maroon predecessors—localized power and figurative escape from the whims of White governance. Using archival data, public databases, and secondary sources on Princeville, North Carolina, I argue that Black towns are not “towns” in the same way that White-founded towns exist in the United States, not only because of the persistent forms of violence leveled at them, but also because ontologically, Black towns do not develop from the same experiences and purposes as White towns. Despite their formal recognition by the state or other forms of legal status, Black towns often resemble their predecessors, maroon communities, which were extralegal spaces of freedom and alternative land relation formed in resistance to slavery in the West, beginning in the sixteenth century. The Town of Princeville established models of land and community relations that supersede capitalist development paradigms undergirding the municipality. This research builds on previous studies of contemporary plantation power relations, marronage, and Black place development and proposes alternative modes of place based on lessons from Princeville.
Role of Interlayer Coupling in the Second Harmonic Generation of Bilayer Transition-metal Dichalcogenides

description: Little is known about the role of weak interlayer coupling in the second harmonic generation (SHG) effects of two-dimensional van der Waals (vdW) systems. In this article, taking homo-bilayer $MoS_2/MoS_2$ and hetero-bilayer $MoS_2/MoSe_2$ as typical examples, we have systemically investigated their SHG susceptibilities as a function of interlayer hopping strength using first-principles calculations. For the SHG at zero frequency limit of both $MoS_2/MoS_2$ and $MoS_2/MoSe_2$, although the increase of tint can increase the intensities of interlayer optical transitions (IOT), the increased band repulsion around G point can eventually decrease their SHG values; the larger the tint, the smaller the SHG response. For the SHG spectra of $MoS_2/MoSe_2$ in the low photon-energy region, opposite to the $MoS_2/MoS_2$, their peak values are very sensitive to the variable tint, due to the strong $t_{int}$-dependent IOT dominating in the band edge; the larger the tint, the larger the SHG. For the SHG of $MoS_2/MoS_2$ in the high photon-energy region, comparing to the $MoS_2/MoSe_2$, their peak values will decrease in a much more noticeable way as the $t_{int}$ increases, due to the larger reduction of band nesting effect. Our study not only can successfully explain the puzzling experimental observations for the different SHG responses in different bilayer transition-metal dichalcogenides under variable tint, but also may provide a general understanding for designing controllable the SHG effects in the vdW systems.

Inaction, Silence, Focus, and Power: Identifying and Assessing Folk Theories of the Racism of Omission
Creators: name: Warren, Evangeline

Publisher: name: Oxford University Press (OUP)
Year: 2023

description:
Recent scholarship has advanced a concept of racism operating through omission. Omission captures both inaction and action, highlighting how systems of oppression rely on inertia in addition to discriminatory action to perpetuate inequality. Yet little is known about how laypersons understand the role of omission in propagating racism in the United States. Building on this premise, we employ a mixed-methods approach to document and test folk theories of the racism of omission. We interview diverse individuals (N=40) about their appraisals of racism; we use these findings to design a vignette study which we fielded to a national sample (N=1,174). Interview data reveal that some Americans do understand omission to be a form of racism, highlighting (1) bystander inaction, (2) silencing of experiences of racism, (3) overfocus on White issues, and (4) disparities in positions of power as instances where inaction, exclusion, or inertia constitute a form of racism. Data show that Americans are most likely to consider overfocus and silencing as forms of omission-based racism, and that racism appraisals depend on the victim’s race. We find that political ideology, gender, income, race, and education shape appraisals of racism as omission. These findings have implications for measures of perceived racism and discrimination.

description: Twitter is one of the most popular social networks attracting millions of users, while a considerable proportion of online discourse is captured. It provides a simple usage framework with short messages and an efficient application programming interface (API) enabling the research community to study and analyze several aspects of this social network. However, the Twitter usage simplicity can lead to malicious handling by various bots. The malicious handling phenomenon expands in online discourse, especially during the electoral periods, where except the legitimate bots used for dissemination and communication purposes, the goal is to manipulate the public opinion and the electorate towards a certain direction, specific ideology, or political party. This paper focuses on the design of a novel system for identifying Twitter bots based on labeled Twitter data. To this end, a supervised machine learning (ML) framework is adopted using an Extreme Gradient Boosting (XGBoost) algorithm, where the hyper-parameters are tuned via cross-validation. Our study also deploys Shapley Additive Explanations (SHAP) for explaining the ML model predictions by calculating feature importance, using the game theoretic-based Shapley values. Experimental evaluation on distinct Twitter datasets demonstrate the superiority of our approach, in terms of bot detection accuracy, when compared against a recent state-of-the-art Twitter bot detection method.

description: In the first part of the talk we discuss the role of the two-body nucleon-nucleon correlations on signatures of the heavy-ion collisions which are a priori expected to be sensitive to these effects. We find that while the fluctuations of the number of produced particles are indeed affected, other quantities (v_2 fluctuations, size fluctuations) are insensitive to the presence of the NN correlations in the nucleon distributions. In the second part we show that the fluctuations of the transverse size of the initial source cause, after a suitable hydrodynamic evolution, fluctuations of the transverse flow velocity at hadronic freeze-out. This in turn yields the event-by-event fluctuations of the transverse momentum of the produced particles, p_T. Our results demonstrate that practically all of the observed event-by-event p_T fluctuations may be explained this way.

description: We study the structural and environmental dependence of the star formation on the plane of stellar mass versus central core density ($Σ_{\rm 1\ kpc}$) in the nearby universe. We study the central galaxies in the sparse environment and find a characteristic population-averaged $\rm Σ_{1\ kpc} \sim 10^9-10^{9.2}\ M_{\odot}\ kpc^{-2}$, above which quenching is operating. This $\rm Σ^{crit}_{1\ kpc}$ only weakly depends on the stellar mass, suggesting that the mass-quenching of the central galaxies is more closely related to the processes that operate in the central regions than over the entire galaxies. For satellites, at a given stellar mass, environment-quenching appears to operate in a similar fashion as mass-quenching in centrals, also starting from galaxies with high $\rm Σ_{1\ kpc}$ to low $\rm Σ_{1\ kpc}$, and $\rm Σ^{crit}_{1\ kpc}$ becomes strongly mass-dependent, in particular in dense regions. This is because (1) more low-mass satellites are quenched by the environmental effects in denser regions and (2) at fixed stellar mass and environment, the environment-quenched satellites have, on average, larger $Σ_{\rm 1\ kpc}$, $\rm M_{1\ kpc}/M_{\star}$ and Sersic index $n$, and as well as smaller size. These results imply that either some dynamical processes change the structure of the satellites during quenching or the satellites with higher $Σ_{\rm 1\ kpc}$ are more susceptible to the environmental effects.

description: Two kagome compounds, volborthite Cu3V2O7(OH)2-2H2O and herbertsmithite ZnCu3(OH)6Cl2, are compared in order to derive information about the intrinsic properties of the spin-1/2 kagome antiferromagnet. Volborthite shows a broad maximum at T ~ J / 4 and the approach at T = 0 to a large finite value of the bulk magnetic susceptibility chi_bulk as well as the local susceptibility chi_local from NMR measurements. These must be intrinsic properties for the spin-1/2 kagome antiferromagnet, as similar behavior has also been reported in chi_local for herbertsmithite [Olariu A et al. 2008 Phys. Rev. Lett., 100 087202]. Impurity effects that may significantly influence the bulk properties are discussed.

‘Everyone just gets that we’re mixed’: racial identification among Puerto Ricans in New York City and Orlando
Creators: name: Viera, Janelle Ashley
Publisher: name: Taylor & Francis
Year: 2023

description:
Previous research shows that racial identification patterns among stateside Puerto Ricans deviate from the Black-White binary that has historically characterized the U.S. colour line. Thus, scholars and policymakers continue to debate the most accurate approach for racially classifying the stateside Puerto Rican – and broader Latinx – population. I address this debate by examining the process of racial identification among Puerto Ricans living in New York City and Orlando, Florida. Data from 58 in-depth interviews and the U.S. Census show that Puerto Ricans merge racial and ethnic conceptualizations when constructing racial identities. This is why most Puerto Ricans report their race as Hispanic/Latina/o. Place-based differences in racial identification also emerge, particularly when respondents are presented with separate race and Hispanic origin questions. I argue that the timing of Puerto Rican migration and the racial histories and demography of each place lead Puerto Ricans to develop different understandings of race.

description: We present an algorithm for decomposing a symmetric tensor, of dimension n and order d as a sum of rank-1 symmetric tensors, extending the algorithm of Sylvester devised in 1886 for binary forms. We recall the correspondence between the decomposition of a homogeneous polynomial in n variables of total degree d as a sum of powers of linear forms (Waring's problem), incidence properties on secant varieties of the Veronese Variety and the representation of linear forms as a linear combination of evaluations at distinct points. Then we reformulate Sylvester's approach from the dual point of view. Exploiting this duality, we propose necessary and sufficient conditions for the existence of such a decomposition of a given rank, using the properties of Hankel (and quasi-Hankel) matrices, derived from multivariate polynomials and normal form computations. This leads to the resolution of polynomial equations of small degree in non-generic cases. We propose a new algorithm for symmetric tensor decomposition, based on this characterization and on linear algebra computations with these Hankel matrices. The impact of this contribution is two-fold. First it permits an efficient computation of the decomposition of any tensor of sub-generic rank, as opposed to widely used iterative algorithms with unproved global convergence (e.g. Alternate Least Squares or gradient descents). Second, it gives tools for understanding uniqueness conditions, and for detecting the rank.
Remarques de Jean-Claude Risset

Publisher: name: Musica/Tecnologia
Year: 2010

description: Jean-Claude Risset analyzes the role of computer science in relation to the creation of music, highlighting the need for the composers to create their ‘own’ resources through a specific research activity, similar to what happened in the path that has seen the birth and development of the electric technologies and, later, of the digital ones. Activities that can and should – thanks to the possibilities increasingly offered today by programming languages – be kept alive, so that we can achieve a new type of complementarity between the composer and the work, as called for by Célestin Deliège.

“Cities too busy to hate”: Economic development through a diversity ideology lens

description:
As economic inequality among racial and ethnic groups persists, debate continues about the role of diversity, equity, and inclusion (DEI) as guiding values to promote equitable economic growth and development. This project uses diversity ideology as a framework to examine how proposals for Amazon’s second headquarters (HQ2) reflect applicants’ beliefs and value systems around racial and ethnic diversity, equity, and inclusion. In our sample of 70 proposals, respondents layered four primary tactics: disregard, limited engagement, acknowledgment without culpability, and value claiming. Prominent approaches included avoidance of any discussion of diversity, objectification of racial and ethnic minority populations as an economic or cultural input, and the assertion a racially and ethnically diversity workforce is an attainable goal while utilizing stereotypes. Each of these approaches reflects different ways racial and ethnic minority populations remain marginalized within economic development proposals, even when firms actively solicit information on their presence and support.

description: Nanotechnology has already made indelible dents in the fields of communication, computation, electronics, photonics, gas sensors, diagnostic technologies, catalysis, drug delivery systems and imaging. In particular, ZnO nanostructures have attracted a lot of research interest due to their unique structure- and size-dependent electrical, optical, and mechanical properties. ZnO nanosystems are abundant with respect to a wide variety of morphologies whose syntheses are critically dependent on several experimental parameters. Cursory presentation of the immense potential of these tiny systems and the state-of-the-art of the synthetic methodologies along with our initial research on ZnO nanorods has been presented. ZnO nanorods in the size range 50-150nm have been synthesized by solid-state route by heating zinc acetate with caustic soda under specific growth conditions. X-ray diffraction pattern unequivocally establishes a wurtzite structure. Scanning electron microscope images of ZnO nanorods display a random distribution of non-uniform size ranges. The manipulation of ZnO nanosystems by fine tuning the critical band gap of this unique semiconductor by doping with divalent transition metal ions leading to novel nanosystems to enhance the performance of the electronic devices is our extended area of research.

«Mi par di trovarmi di fronte a un fatto nuovo letterario»: Carlo Linati alla scoperta di James Joyce
Creators: name: Pasquero, Maurizio
Publisher: name: Biblioteca di Studi di Filologia Moderna: Series, Journals and Workshop
Year: 2013

description: Carlo Linati was Joyce’s first translator into Italian. The two writers started corresponding in 1918 and kept in touch throughout the 1930s. They only met once in 1930 in Paris. Joyce had a high opinion of Linati, but – after his «gran rifiuto» concerning Ulysses – their paths separated. Nevertheless Linati did devote his last years to translating Dubliners and Stephen Hero. The essay reconstructs their long relationship by means of rare unpublished documents and letters.

description: A tracking detector is proposed for lepton flavor violation experiments ($μ\to e$ conversion, $μ\to e + γ$, $μ\to 3e $) consisting of identical chambers which can be reconfigured to meet the requirements for all three experiments. A pattern recognition and track reconstruction procedure based on the Kalman filter technique is presented for this detector. The pattern recognition proceeds in two stages. At the first stage only hit straw tube center coordinates, without drift time information, are used to reduce the background to a manageable level. At the second stage the drift time information is incorporated and a deterministic annealing filter is applied to reach the final level of background suppression. The final track momentum reconstruction is provided by a combinatorial drop filter which is effective in hit-to-track assignment. The momentum resolution of the tracker in measuring monochromatic leptons is found to be $σ_{p}$ = 0.17 and 0.26 MeV for the $μ\to e$ conversion and $μ^+ \to e^+ + γ$ processes, respectively. The tracker reconstruction resolution for the total scalar lepton momentum is $σ_{p} = $ 0.33 MeV for the $μ\to 3e$ process. The obtained tracker resolutions allow an increase in sensitivity to the branching ratios for these processes by a few orders of magnitude over current experimental limits.

description: The shear viscosity coefficient and the corresponding relaxation time for causal dissipative hydrodynamics are calculated based on the microscopic formula proposed in [T. Koide and T. Kodama, Phys. Rev. \textbf{E 78}, 051107 (2008)]. Here, the exact formula is transformed into a more compact form and applied it to evaluate these transport coefficients in the chiral perturbation theory and perturbative QCD. It is shown that in the leading order calculation, the causal shear viscosity coefficient $η$ reduces to that of the ordinary Green-Kubo-Nakano formula, and the relaxation time $τ_π$ is related to $η$ and pressure $P$ by a simple relationship, $τ_π=η/P$.
