description: As a common view the hydrophobic association between molecular-scale binding partners is supposed to be dominantly driven by entropy. Recent calorimetric experiments and computer simulations heavily challenge this established paradigm by reporting that water's thermodynamic signature in the binding of small hydrophobic ligands to similar-sized apolar pockets is enthalpy-driven. Here we show with purely geometric considerations that this controversy can be resolved if the antagonistic effects of concave and convex bending on water interface thermodynamics are properly taken into account. A key prediction of this continuum view is that for fully complementary binding of the convex ligand to the concave counterpart, water shows a thermodynamic signature very similar to planar (large-scale) hydrophobic association, that is, enthalpy-dominated, and hardly depends on the particular pocket/ligand geometry. A detailed comparison to recent simulation data qualitatively supports the validity of our perspective down to subnanometer scales. Our findings have important implications for the interpretation of thermodynamic signatures found in molecular recognition and association processes. Furthermore, traditional implicit solvent models may benefit from our view with respect to their ability to predict binding free energies and entropies.

title: Narratives of Governance: Understanding Responses to Street Homelessness in Canterbury
Creators: name: Varnava, Tracey
Publisher: name: University of Kent
Year: 2024

description: In this thesis I examine the complexities and inconsistencies of the contemporary governance of street homelessness by exploring a particular locale, the city of Canterbury in Kent. Drawing on interdisciplinary perspectives I engage with governance as it presents in Canterbury, expanding existing literature by investigating novel and under researched spaces and practices. 
My research, and this thesis, traverses the city. It begins in a local churchyard, passing through the Business Improvement District, into a city centre park before concluding with visits to two homeless charities. In each site I unravel the connections between the contexts in which governance is practised and the range of responses to street homelessness. I explore and critique notions of localism illustrating how responsibility for homelessness has become dispersed and obscured. Further, my analysis problematises universalising accounts of the effects of neoliberalism on the governance of street homelessness in urban settings, uncovering a more varied and variable reality: highlighting, for example, how the stories told about the history, character, and values in and of a city inflect the approach to governance. 
I employ a methodology that juxtaposes a close and contextually rich reading of the narratives composed and communicated by different governance actors with the findings from my empirical research. This distinctive approach provides an original account of urban governance, revealing underlying contingencies and demonstrating the significance of local context as a productive site for assessing and extending contemporary discourses of street homelessness. 
This thesis proposes that a more nuanced understanding of the governance of street homelessness is possible by paying attention to local context, and the spaces and agencies that are less commonly the focus of analysis. I argue that this approach serves to unravel and reframe usual oppositional explanatory constructs such as deserving/undeserving, compassionate/punitive, public/private, indolent/productive, and unsettles theories of localism and neoliberalism by placing them in the everyday. In doing so, fresh perspectives emerge of street homelessness and the spaces, rationalities, and practices of governance.
Qubit-oscillator system: An analytical treatment of the ultra-strong coupling regime

description: We examine a two-level system coupled to a quantum oscillator, typically representing experiments in cavity and circuit quantum electrodynamics. We show how such a system can be treated analytically in the ultrastrong coupling limit, where the ratio $g/Ω$ between coupling strength and oscillator frequency approaches unity and goes beyond. In this regime the Jaynes-Cummings model is known to fail, because counter-rotating terms have to be taken into account. By using Van Vleck perturbation theory to higher orders in the qubit tunneling matrix element $Δ$ we are able to enlarge the regime of applicability of existing analytical treatments, including in particular also the finite bias case. We present a detailed discussion on the energy spectrum of the system and on the dynamics of the qubit for an oscillator at low temperature. We consider the coupling strength $g$ to all orders, and the validity of our approach is even enhanced in the ultrastrong coupling regime. Looking at the Fourier spectrum of the population difference, we find that many frequencies are contributing to the dynamics. They are gathered into groups whose spacing depends on the qubit-oscillator detuning. Furthermore, the dynamics is not governed anymore by a vacuum Rabi splitting which scales linearly with $g$, but by a non-trivial dressing of the tunneling matrix element, which can be used to suppress specific frequencies through a variation of the coupling.

Network Code Design for Orthogonal Two-hop Network with Broadcasting Relay: A Joint Source-Channel-Network Coding Approach

description: This paper addresses network code design for robust transmission of sources over an orthogonal two-hop wireless network with a broadcasting relay. The network consists of multiple sources and destinations in which each destination, benefiting the relay signal, intends to decode a subset of the sources. Two special instances of this network are orthogonal broadcast relay channel and the orthogonal multiple access relay channel. The focus is on complexity constrained scenarios, e.g., for wireless sensor networks, where channel coding is practically imperfect. Taking a source-channel and network coding approach, we design the network code (mapping) at the relay such that the average reconstruction distortion at the destinations is minimized. To this end, by decomposing the distortion into its components, an efficient design algorithm is proposed. The resulting network code is nonlinear and substantially outperforms the best performing linear network code. A motivating formulation of a family of structured nonlinear network codes is also presented. Numerical results and comparison with linear network coding at the relay and the corresponding distortion-power bound demonstrate the effectiveness of the proposed schemes and a promising research direction.

Contribution of Phospholipase C-Delta 4 to calcium signaling in astrocytes
Creators: name: Kamyabi, Alireza
Publisher: name: University of British Columbia
Year: 2022

description: As the most abundant cell type in the brain, astrocytes play a key role in neural functions and form complex interacting networks with neural circuits in various brain regions. Although not electrically excitable, astrocytes exhibit a complex repertoire of intracellular Ca²⁺ dynamics. Rapid elevations in intracellular Ca²⁺ concentration, known as Ca²⁺ events, are postulated to be one of the main intracellular signaling pathways in astrocytes and are thought to mediate key astrocytic functions including neuromodulation and bidirectional control of arteriole diameter. Ca²⁺ events in astrocytes exhibit a variety of spatiotemporal properties – ranging from fast, transient, and localized microdomain Ca²⁺ sparks to network-wide Ca²⁺ wave propagations that span across the astrocytic network. The mechanisms underlying the spatiotemporal properties of Ca²⁺ events, importantly their propagation both intracellularly and in astrocytic networks, remain elusive. Theoretical studies of Ca²⁺ propagation in astrocytes have previously posited that IP₃₋dependent Ca²⁺-induced Ca²⁺ release driven by Phospholipase C delta proteins act as an important regulator of Ca²⁺ propagation in astrocytes. Here we investigate the contribution of Phospholipase C delta 4 (PLCD4) to Ca²⁺ dynamics in astrocytes and demonstrate that PLCD4 is functionally expressed in the brain and in astrocytes. Using PLCD4-/- mice, we demonstrate that PLCD4 is an essential mediator of Ca²⁺ release from intracellular Ca²⁺ stores and acts to prolong and enhance IP₃₋mediated Ca²⁺ release following G𝑞-linked GPCR activation. Furthermore, we show that PLCD4 activity contributes to regulating the propagation and size of Ca²⁺ events in astrocytes. In PLCD-/- mice, astrocyte Ca²⁺ sparks exhibit reduced propagation and are smaller in size compared to sparks in PLCD4+/+ mice. Lastly, we report that network-wide Ca²⁺ wave propagations are still present in PLCD4-/- mice. Together, this data suggests that PLCD4 in astrocytes plays an important functional role in regulating Ca²⁺ release from the ER and acts as a secondary enhancer of astrocytic Ca²⁺ events. Subsequently, these findings suggest that PLCD4 may play a role in regulating Ca²⁺-mediated functions and paves the way for future studies to investigate the functional role of Ca²⁺ propagation in astrocytes.

description: A hex sphere is a singular Euclidean sphere with four cone points whose cone angles are (integer) multiples of $\frac{2π}{3}$ but less than $2π$. We prove that the Moduli space of hex spheres of unit area is homeomorphic to the the space of similarity classes of Voronoi polygons in the Euclidean plane. This result gives us as a corollary that each unit-area hex sphere $M$ satisfies the following properties: (1) it has an embedded (open Euclidean) annulus that is disjoint from the singular locus of $M$; (2) it embeds isometrically in the 3-dimensional Euclidean space as the boundary of a tetrahedron; and (3) there is a simple closed geodesic $γ$ in $M$ such that a fractional Dehn twist along $γ$ converts $M$ to the double of a parallelogram.

description: The dynamics of a one-dimensional stochastic model is studied in presence of an absorbing boundary. The distribution of fluctuations is analytically characterized within the generalized van Kampen expansion, accounting for higher order corrections beyond the conventional Gaussian approximation. The theory is shown to successfully capture the non Gaussian traits of the sought distribution returning an excellent agreement with the simulations, for {\it all times} and arbitrarily {\it close} to the absorbing barrier. At large times, a compact analytical solution for the distribution of fluctuations is also obtained, bridging the gap with previous investigations, within the van Kampen picture and without resorting to alternative strategies, as elsewhere hypothesized.

Quark running mass and vacuum energy density in truncated Coulomb gauge QCD for five orders of magnitude of current masses
Creators: name: Bicudo, P.
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study in detail the effect of the finite current quark mass on chiral symmetry breaking, in the framework of truncated Coulomb gauge QCD with a linear confining quark-antiquark potential. In the chiral limit of massless current quarks, the breaking of chiral symmetry is spontaneous. But for a finite current quark mass, some dynamical symmetry breaking continues to add to the explicit breaking caused by the quark mass. Moreover, using as order parameter the mass gap, i. e. the quark mass at vanishing moment or the quark condensate, a finite quark mass transforms the chiral symmetry breaking from a phase transition into a crossover. For the study of the QCD phase diagram it thus is relevant to determine how the current quark mass affects chiral symmetry breaking. Since the current quark masses of the six standard flavours u, d, s, c, b, t span over five orders of magnitude from 1.5 MeV to 171 GeV, we develop an accurate numerical method to study the running quark mass gap and the quark vacuum energy density from very small to very large current quark masses.

“Hail to the Queen of the May!” : settler futurity, childhood, and the May Queens of New Westminster, 1858-1939
Creators: name: Twiss, Georgia Rose
Publisher: name: University of British Columbia
Year: 2022

description: This thesis examines the intimate relationship forged between the traditional British festival May Day, the celebration’s main figure the May Queen, and white settler society in New Westminster between the event’s earliest beginnings in 1858 and the end of the interwar years in 1939. In doing so, this thesis argues that the advent and ongoing celebration of May Day in the city was part of a larger project of collective aspiration—what scholars term settler futurity—that fundamentally defined settler colonialism in British Columbia, and elsewhere, from the mid-nineteenth century onwards. The May Queen, performed in these years through the body of a white settler girl between the ages of ten and sixteen, served as the ultimate symbol of this futurity and a powerful community figure around which gendered and racialized notions of collective identity, civic loyalty and belonging took shape. In this, the annual embodied performance of the May Queen – supported by her Maids of Honour and the Honour Guard of white settler boys – functioned as a crucial means of investing children with the gendered behavioural expectations and responsibilities necessary to represent and uphold the cisheteronormative patriarchal logics of settler colonialism that would ensure the longevity of a stable white settler future in the city. This examination of May Day and the May Queens of New Westminster, then, reveals the critical role that white settler children, in particular white settler girls, played as politicized subjects in the construction and maintenance of local colonial power and settler society in British Columbia from the mid-nineteenth century onwards.

description: In this paper we review and discuss some of the intriguing properties of the Galactic Center supermassive black hole candidate Sgr A*. Of all possible black hole sources, the event horizon of Sgr A*, subtends the largest angular scale on the sky. It is therefore a prime candidate to study and image plasma processes in strong gravity and it even allows imaging of the shadow cast by the event horizon. Recent mm-wave VLBI and radio timing observations as well as numerical GRMHD simulations now have provided several breakthroughs that put Sgr A* back into the focus. Firstly, VLBI observations have now measured the intrinsic size of Sgr A* at multiple frequencies, where the highest frequency measurements have approached the scale of the black hole shadow. Moreover, measurements of the radio variability show a clear time lag between 22 GHz and 43 GHz. The combination of size and timing measurements, allows one to actually measure the flow speed and direction of magnetized plasma at some tens of Schwarzschild radii. This data strongly support a moderately relativistic outflow, consistent with an accelerating jet model. This is compared to recent GRMHD simulation that show the presence of a moderately relativistic outflow coupled to an accretion flow Sgr A*. Further VLBI and timing observations coupled to simulations have the potential to map out the velocity profile from 5-40 Schwarzschild radii and to provide a first glimpse at the appearance of a jet-disk system near the event horizon. Future submm-VLBI experiments would even be able to directly image those processes in strong gravity and directly confirm the presence of an event horizon.

Dopo una sintetica ricostruzione del dibattito europeo – da Montesquieu a Mirabeau – il saggio si concentra sul Della Tirannide, mostrando i suoi elementi di originalità: il suo taglio incisivamente politologico, la sua serrata struttura lo-gico-argomentativa, la prospettiva risolutamente repubblicana arricchita da in-serti proto-liberali e soprattutto la definizione del dispotismo europeo come dispo-tismo dissimulato, perché coperto dal velo ingannevole dell'apparato legale. The essay’s aim to read Della Tirannide as a critical and polemical work, in order to adequately assess its so far neglected role within the European debate on des-potism. Followin a brief reconstruction of the latter, from Montesquieu to Mira-beau, the essay will focus on Della Tirannide, showing the elements of its original-ity, such as its uniquely political flair, its tight logical-argumentative structure, its adamantly republican perspective, enriched by proto-liberal accents, and, most importantly, the definition of European despotism as a covert, its tyrannical nature concealed by its legal system.

Phenomenological Ginzburg-Landau-like theory for superconductivity in the cuprates

description: We propose a phenomenological Ginzburg-Landau-like theory of cuprate superconductivity. The free energy is expressed as a functional F of the spin-singlet pair amplitude psi_ij=psi_m=Delta_m exp(i phi_m); i and j are nearest-neighbor sites of the Cu lattice in which the superconductivity is believed to primarily reside and m labels the site at the center of the bond between i and j. The system is modeled as a weakly coupled stack of such planes. We hypothesize a simple form, F[Delta,phi]=sum_m (A Delta_m^2+ B Delta_m^4/2)+C sum_ Delta_m Delta_n cos(phi_m-phi_n), for the functional. The coefficients A, B and C are determined from comparison with experiments. We work out a number of consequences of the proposed functional for specific choices of A, B and C as functions of hole density x and temperature T. There can be a rapid crossover of from small to large values as A changes sign on lowering T and the crossover temperatures is identified with the observed pseudogap temperature. The superconducting phase-coherence transition occurs at a different temperature T_c, and describes superconductivity with d-wave symmetry for C>0. We calculate T_c(x) which has the observed parabolic shape, being strongly influenced by the coupling between Delta_m and phi_m present in F. The superfluid density, the local gap magnitude, the specific heat (with and without a magnetic field) and vortex properties are obtained using F. We compare our results successfully with experiments. We also obtain the electron spectral density as influenced by the coupling between the electrons and the pair correlation function calculated from F. Features such as temperature dependent Fermi arcs, antinodal pseudogap filling temperature, pseudogapped density of states in different momentum regions of the Fermi surface and `bending' of the energy gap versus momentum on the Fermi surface emerge from the theory.

Alfieri e la prerivoluzione francese (1787-1789)

description: Con la pubblicazione a Parigi, nella primavera del 1787, del Panegirico pseudo-pliniano Alfieri intendeva non solo realizzare una semplice prova tipografica in vista della stampa delle sue opere, ma voleva intervenire nel dibattito politico aperto dalla convocazione dell’Assemblée des Notables. In questa prospettiva deve essere letta anche la sua traduzione, stampata nell’estate del 1787, quando comin-cia la battaglia per la convocazione degli Stati Generali, di cui l’amico Jean-An-toine Sabatier de Cabre fu uno dei protagonisti. Con questa operazione editoriale Alfieri sembra sostenere le posizioni del futuro ‘parti national’, che avrebbe riunito l’aristocrazia liberale e la borghesia nella battaglia contro l’assolutismo e contro i privilegi della società d’ordini. Alfieri sembrava essersi schermito quando il ge-nerale olandese van Rijssel lo aveva invitato a indirizzare il Panegirico allo Statholder Guglielmo V. Tuttavia, l’invio, forse solo progettato, a Luigi XVI con-ferma la funzione operativa che Alfieri attribuiva alla sua opera e l’adesione piena al progetto di trasformazione della Francia in una monarchia costituzionale. By publishing in Paris, in the spring 1787, his Pseudo-Plinian Panegyric, Alfieri did not only intend to carry out a simple typographical test in view of the printing of his works, but he also wanted to contribute to the political debate launched by the convocation of the Assemblée des Notables. This is the context in which should be read his translation, printed in the summer 1787, when the battle for the convocation of the Estates General, of which his friend Jean-Antoine Sabatier de Cabre was a protagonist, bagan. By this editorial operation Alfieri seems to support the position of the future ‘parti national’, which would bring together the liberal aristocracy and the bourgeoisie in a battle against absolutism and the privileges of the society of orders. Alfieri seemed to have shielded himself when the Dutch general van Rijssel suggested him to address his Panegyric to the Stadtholder William V. However, the (maybe only planned) intention to send his Panegyric to Louis XVI confirms the operative function that Alfieri attached to his work and his full agreement to the project of turning France into a constitutional monarchy.

Spaces of value in William Gaddis's The Recognitions
Creators: name: Williams, Jack
Publisher: name: University of British Columbia
Year: 2022

description: This thesis provides a thorough analysis of Williams Gaddis’s depiction of capitalism and American imperialism in his magnum opus, The Recognitions (1955). Often read as a late Modernist, early Postmodernist text primarily concerned with aesthetic and spiritual questions, this thesis argues that The Recognitions also exhibits a profound concern with the changing material realities of lived space under intra- and post-World War II American capitalism. The first chapter analyzes the scenes set in New York through the lens of Henri Lefebvre’s concept of “abstract space” to relate Gaddis’s depictions of urban infrastructure to his critique of the decline of civic culture through alienation and overreliance on mass media. The second chapter argues that The Recognitions prefigures the critique of American imperialism that becomes central to Gaddis’s mid-career works, J R (1975) and Carpenter’s Gothic (1985). Through a critical examination of the text’s depiction of non-American spaces (Paris, Central America, and Spain), it demonstrates how American industries commodify cultural practices and overwrite Indigenous spatial arrangements to subordinate all other ways of life to the demands of capital. The second chapter concludes by examining the scenes set in the Spanish countryside, linking the novel’s spatial themes with its aesthetic and spiritual ones through a discussion of Gaddis’s descriptions of monumental built structures. Drawing on philosopher G.A. Cohen’s distinction between preserving particular valuable things and preserving value as such, it argues that the depictions of enduring monuments present a spatial metaphor for an attitude toward value more broadly, one that resists the reductive, utilitarian attitude that shapes the novel’s other spatial arrangements. In asserting the centrality of space as an important category for understanding The Recognitions’ depiction of capitalism and identifying the presence of Gaddis’s later critiques of imperialism in his earliest work, this thesis enriches our understanding of Gaddis’s engagement with the socio-economic realities of his time and identifies an avenue for further inquiry into the global aspects of his fiction.

description: Based on previous spectral and temporal optical studies, Q2122-444 has been classified as a naked AGN or true type 2 AGN, that is, an AGN that genuinely lacks a broad line region (BLR). Its optical spectrum seemed to possess only narrow forbidden emission lines that are typical of type 2 (obscured) AGNs, but the long-term optical light curve, obtained from a monitoring campaign over more than two decades, showed strong variability, apparently ruling out the presence of heavy obscuration. Here, we present the results from a ~40 ks XMM-Newton observation of Q2122-444 carried out to shed light on the energetics of this enigmatic AGN. The X-ray analysis was complemented with ATCA radio data to assess the possible presence of a jet, and with new NTT/EFOSC2 optical spectroscopic data to verify the actual absence of a BLR. The higher-quality optical data revealed the presence of strong and broad Balmer lines that are at odds with the previous spectral classification of this AGN. The lack of detection of radio emission rules out the presence of a jet. The X-ray data combined with simultaneous UV observations carried out by the OM aboard XMM-Newton confirm that Q2122-444 is a typical type-1 AGN without any significant intrinsic absorption. New estimates of the black hole mass independently obtained from the broad Balmer lines and from a new scaling technique based on X-ray spectral data suggest that Q2122-444 is accreting at a relatively high rate in Eddington units.

description: We have used the Spitzer satellite to monitor the mid-IR evolution of SN 1987A over a 5 year period spanning the epochs between days 6000 and 8000 since the explosion. The supernova (SN) has evolved into a supernova remnant (SNR) and its radiative output is dominated by the interaction of the SN blast wave with the pre-existing equatorial ring (ER). The mid-IR spectrum is dominated by emission from ~180 K silicate dust, collisionally-heated by the hot X-ray emitting gas with a temperature and density of ~5x10^6 K and 3x10^4 cm-3, respectively. The mass of the radiating dust is ~1.2x10^(-6) Msun on day 7554, and scales linearly with IR flux. The infrared to soft-X-ray flux ratio is roughly constant with a value of 2.5. Gas-grain collisions therefore dominate the cooling of the shocked gas. The constancy of of this ratio suggests that very little grain processing or gas cooling have occurred throughout this epoch. The shape of the dust spectrum remained unchanged during the observations while the total flux increased with a time dependence of t^(0.87), t being the time since the first encounter between the blast wave and the ER. These observations are consistent with the transitioning of the blast wave from free expansion to a Sedov phase as it propagates into the main body of the ER.

La grande fortuna teatrale di Alfieri e il suo corrispon-dente mito politico quale profeta dell’imminente risorgimento e dell’unità d’Italia nascono nel ‘triennio giacobino’ per poi prolungarsi all'intero Ottocento. L’inter-pretazione dell’Alfieri quale profeta della libertà e dell’unità d’Italia viene svilup-pata in particolare da De Sanctis. Il saggio ricostruisce lo svolgimento di questa interpretazione della figura e dell’opera di Alfieri. From 1796 onwards, all the conditions favorable to the success of a literary work that became the bearer of new patriotic ideals such as the Alfierian work were created in Italy: a success essentially aimed at the political contents of the trage-dies and treaties. The great theatrical success of Alfieri and his corresponding po-litical myth as a prophet of the imminent Risorgimento and the unity of Italy were born in the ‘Jacobin triennium’ and then extended to the entire Nineteenth century. The interpretation of Alfieri as a prophet of freedom and the unity of Italy is devel-oped in particular by De Sanctis. The essay reconstructs the development of this interpretation of the figure and work of Alfieri.

description: Composite spectra of 85 proximate absorbers (log N(HI)>20 and velocity difference between the absorption and emission redshift, dv<10,000 km/s) in the SDSS are used to investigate the trends of metal line strengths with velocity separation from the QSO. We construct composites in 3 velocity bins: dv<3000 km/s, 30006000 km/s, with further sub-samples to investigate the metal line dependence on N(HI) and QSO luminosity. Low (e.g. SiII and FeII) and high ionization (e.g. SiIV and CIV) species alike have equivalent widths (EWs) that are larger by factors of 1.5 -- 3 in the dv<3000 km/s composite, compared to the dv>6000 km/s spectrum. The EWs show an even stronger dependence on dv if only the highest neutral hydrogen column density (log N(HI)>20.7) absorbers are considered. We conclude that PDLAs generally have higher metallicities than intervening absorbers, with the enhancement being a function of both dv and N(HI). It is also found that absorbers near QSOs with lower rest-frame UV luminosities have significantly stronger metal lines. We speculate that absorbers near to high luminosity QSOs may have had their star formation prematurely quenched. Finally, we search for the signature of dust reddening by the PDLAs, based on an analysis of the QSO continuum slopes relative to a control sample and determine a limit of E(B-V)<0.014 for an SMC extinction curve. This work provides an empirical motivation for distinguishing between proximate and intervening DLAs, and establishes a connection between the QSO environment and galaxy properties at high redshifts.

Il «romanzo» di Londra

description: Il saggio ricostruisce la storia d’amore tra Vittorio Alfieri e Penelope Pitt, che si svolse a Londra nel maggio del 1771, dal punto di vista dell’opinione pubblica inglese che fu informata minutamente di ogni dettaglio dai giornali e da altre fonti popolari, nel quadro dei profondi mutamenti sociali e culturali avvenuti nel mondo londinese durante il regno di Giorgio III: quando i casi di immoralità e di adulterio degli aristocratici del Beau Monde divennero argomento di conversazione e og-getto di pubblicazioni che gareggiarono con la letteratura erotica e pornografica. Vista in questa ottica, il «caso» Alfieri-Ligonier non ebbe quasi nulla di eccezio-nale e fu trattato dalla stampa come uno dei tanti scandali che ebbero come pro-tagonisti personaggi dell’aristocrazia e che ebbero come centro motore il celebre club denominato «New Female Coterie». Nel resoconto della Vita Alfieri sembra essere rimasto all’oscuro di questo sfondo le cui valenze − come ha mostrato la storiografia degli ultimi venti anni − andavano molto oltre le apparenze libertine e pettegole e furono all’origine di una ripresa di egemonia da parte del ceto ari-stocratico più colto e vicino alle punte avanzate della cultura europea. The essay traces the love story between Vittorio Alfieri and Penelope Pitt, which took place in London in May 1771, taking as an observation point the English pub-lic opinion which was informed in detail by newspapers and other popular sources. In the context of the intense social and cultural changes that occurred during the reign of George III, the cases of immorality and adultery of the aristocrats of the Beau Monde became a topic of conversation and the subject of publications that competed with erotic and pornographic literature. Seen in this light, the ‘Alfieri-Ligonier case’ had almost nothing exceptional and was treated by the press as one of the many scandals that had aristocratic personalities as protagonists, and which had the famous club ‘New Female Coterie’ as its driving force. Beyond the libertine and gossipy appearances, the last twenty years historiography has recognized that these facts were at the origin of a resumption of hegemony by the aristocratic class in contact with the advanced peaks of European culture. But Alfieri seems to have remained unaware of this social background.

description: Chemotherapy is currently an irreplaceable strategy for cancer treatment. Doxorubicin hydrochloride (DOX) is a clinical first-line drug for cancer chemotherapy. While its efficacy for cancer treatment is greatly compromised due to invalid enrichment or serious side effects. To increase the content of intracellular targets and boost the antitumor effect of DOX, a novel biotinylated hyaluronic acid-guided dual-functionalized CaCO3-based drug delivery system (DOX@BHNP) with target specificity and acid-triggered drug-releasing capability was synthesized. The ability of the drug delivery system on enriching DOX in mitochondria and nucleus, which further cause significant tumor inhibition, were investigated to provide a more comprehensive understanding of this CaCO3-based drug delivery system. After targeted endocytosis by tumor cells, DOX could release faster in the weakly acidic lysosome, and further enrich in mitochondria and nucleus, which cause mitochondrial destruction and nuclear DNA leakage, and result in cell cycle arrest and cell apoptosis. Virtually, an effective tumor inhibition was observed in vitro and in vivo. More importantly, the batch-to-batch variation of DOX loading level in the DOX@BHNP system is negligible, and no obvious histological changes in the main organs were observed, indicating the promising application of this functionalized drug delivery system in cancer treatment.

description: In some social and biological networks, the majority of nodes belong to multiple communities. It has recently been shown that a number of the algorithms that are designed to detect overlapping communities do not perform well in such highly overlapping settings. Here, we consider one class of these algorithms, those which optimize a local fitness measure, typically by using a greedy heuristic to expand a seed into a community. We perform synthetic benchmarks which indicate that an appropriate seeding strategy becomes increasingly important as the extent of community overlap increases. We find that distinct cliques provide the best seeds. We find further support for this seeding strategy with benchmarks on a Facebook network and the yeast interactome.

L’alfierismo del Carducci giovane

description: L’autore, che da decenni dedica studi e pubblicazioni sia ad Alfieri che a Carducci, ripercorre il cammino del Carducci principiante dal 1857, anno delle Rime di San Miniato, al 1862, anno nel quale al poeta toscano si apre la via di quella poesia ribellistica e protestataria comunemente conosciuta come giambica, riconoscendo come dominante in questi anni giovanili carducciani la presenza di Alfieri. In Al-fieri Carducci, da poeta risorgimentale, vide il precursore e profeta della terza Italia, e il sublime vate di libertà. Ma la lezione alfieriana non si è certo limitata per Carducci al campo delle idee, giacché il poeta astigiano è stato da lui assunto, in quel suo periodo di tirocinio poetico ma non solo, come modello di lingua e di stile: quel modello di poesia fortemente rilevata sulla prosa e impossibile a con-fondersi con essa che il giovane Giosue andava cercando. S. conclude che l’alfie-rismo carducciano rappresenta un capitolo fondamentale di quello che si può a buon diritto chiamare l’Ottocento alfieriano. The author, who over the last few decades has published a vast number of essays and books on both Alfieri and Carducci, outlines the development of Carducci’s work from his early beginning in 1857, the year of his Rime di San Miniato, to 1862, the year when the Tuscan poet started producing the rebel, protest poetry commonly known as jambic poetry, and emphasizes the dominant presence of Al-fieri in the early years of Carducci’s work. As a poet of the Italian Risorgimento, Carducci saw Alfieri as a forerunner and prophet of the ‘Third Italy’, and as the sublime poet who celebrated freedom. Nevertheless, as Sterpos claims, during Car-ducci’s poetic apprenticeship, but not only at that time, Alfieri’s lesson for Car-ducci was certainly not confined to the field of ideals; the poet from Asti was actu-ally also a golden model for his language and style: precisely that model of poetry that stood well above the prosaic and was impossible to confuse with it that the young Giosue Carducci was searching for. Sterpos concludes that Carducci’s Al-fierism is a fundamental chapter in what can quite rightly be called ‘l’Ottocento alfieriano’, namely the 19th century of Vittorio Alfieri.
