description: La complessità con cui l’urbano si manifesta viene di frequente affrontata specialisticamente e per interdisciplinarietà si intende spesso la possibilità di far dialogare diversi specialismi. Quali sono le basi di questo possibile dialogo, come possa darsi integrazione, gli esiti auspicabili, sono ancora terreno aperto di discussione. Le pagine che seguono intendono riprendere il dibattito circa l’interdisciplinarità negli studi urbani, sollevando alcune piste di riflessione che intendono avvicinarla differentemente da come è oramai incastonata nel mainstreaming della ricerca urbana: da petizione di principio invocata coralmente, di cui si lodano le qualità quasi messianiche per la soluzione dei problemi urbani, a procedura di composizione di diverse metodologie, diversamente intesa e praticata, o frequentemente ostacolata, da silenti ostilità istituzionali, disciplinari, se non epistemologiche. Buzzword si direbbe, che costituitasi negli ultimi quarant’anni come campo di studi distinto per letteratura e dipartimenti (soprattutto nell’universo accademico anglosassone) – gli interdisciplinary studies – sembra destinata, forse, ironia della sorte, a indicare un’ulteriore disciplina non più allo stato nascente.

description: On the basis of data on the decay D^+_s -> pi^+ pi^+ pi^-, which goes dominantly via the transition D_s -> pi^+ s anti-s, we evaluate the 1^3P_0 s anti-s components in the scalar-isoscalar resonances f0(980), f0(1300), f0(1500) and broad state f0(1200-1600)$. The data point to a large s anti-s component in the f0(980): 40% < s anti-s < 70%. Nearly 30% of the 1^3P_0 s anti-s component flows to the mass region 1300-1500 MeV being shared by f0(1300), f0(1500) and broad state f0(1200-1600): the interference of these states results in a peak near 1400 MeV with the width around 200 MeV.

description: Prior to the availability of digital cameras, the solar observational images are typically recorded on films, and the information such as date and time were stamped in the same frames on film. It is significant to extract the time stamp information on the film so that the researchers can efficiently use the image data. This paper introduces an intelligent method for extracting time stamp information, namely, the Convolutional Neural Network (CNN), which is an algorithm in deep learning of multilayer neural network structures and can identify time stamp character in the scanned solar images. We carry out the time stamp decoding for the digitized data from the National Solar Observatory from 1963 to 2003. The experimental results show that the method is accurate and quick for this application. We finish the time stamp information extraction for more than 7 million images with the accuracy of 98\%.

description: This paper investigates the large-time behavior of a buoyancy-driven fluid without thermal diffusion under Navier-slip boundary conditions in a bounded domain with Lipschitz-continuous second derivatives. After establishing improved regularity for classical solutions, we analyze their large-time asymptotics. Specifically, we show that the solutions converge to a state where, as $t \rightarrow \infty$, $\|u\|_{W^{1,p}} \rightarrow 0$, and hydrostatic balance is achieved in the weak topology of $L^2$. Furthermore, we identify the necessary conditions under which stable stratification and hydrostatic balance can be achieved in the strong topology as time approaches infinity. We then analyze a particular steady state, the hydrostatic equilibrium, characterized by $ u = 0 $, $ θ= βx_2 + γ$, and $ p = \fracβ{2}x_2^2 + γx_2 + δ$. In a periodic strip, we establish the linear stability of this state for $β> 0$, indicating that the temperature is vertically stably stratified. This work builds upon the results in [Doering et al.], which focus on free-slip boundary conditions, as well as recent studies [Aydın, Kukavica, Ziane; Aydın, Jayanti] that address no-slip boundary conditions. Notably, the novelty of this study lies in the ability to directly bound the pressure term, made possible by the Navier-slip boundary conditions.

description: We investigate the combined effects of boundaries and topology on the vacuum expectation values (VEVs) of the charge and current densities for a massive 2D fermionic field confined on a conical ring threaded by a magnetic flux. Different types of boundary conditions on the ring edges are considered for fields realizing two inequivalent irreducible representations of the Clifford algebra. The related bound states and zero energy fermionic modes are discussed. The edge contributions to the VEVs of the charge and azimuthal current densities are explicitly extracted and their behavior in various asymptotic limits is considered. On the ring edges the azimuthal current density is equal to the charge density or has an opposite sign. We show that the absolute values of the charge and current densities increase with increasing planar angle deficit. Depending on the boundary conditions, the VEVs are continuous or discontinuous at half-integer values of the ratio of the effective magnetic flux to the flux quantum. The discontinuity is related to the presence of the zero energy mode. By combining the results for the fields realizing the irreducible representations of the Clifford algebra, the charge and current densities are studied in parity and time-reversal symmetric fermionic models. If the boundary conditions and the phases in quasiperiodicity conditions for separate fields are the same the total charge density vanishes. Applications are given to graphitic cones with edges (conical ribbons).

description: Efficient and reliable social bot classification is crucial for detecting information manipulation on social media. Despite rapid development, state-of-the-art bot detection models still face generalization and scalability challenges, which greatly limit their applications. In this paper we propose a framework that uses minimal account metadata, enabling efficient analysis that scales up to handle the full stream of public tweets of Twitter in real time. To ensure model accuracy, we build a rich collection of labeled datasets for training and validation. We deploy a strict validation system so that model performance on unseen datasets is also optimized, in addition to traditional cross-validation. We find that strategically selecting a subset of training data yields better model accuracy and generalization than exhaustively training on all available data. Thanks to the simplicity of the proposed model, its logic can be interpreted to provide insights into social bot characteristics.

description: A new theory for dynamics of concentrated colloidal suspensions and the colloidal glass transition is proposed. The starting point is the memory function representation of the density correlation function. The memory function can be expressed in terms of a time-dependent pair-density correlation function. An exact, formal equation of motion for this function is derived and a factorization approximation is applied to its evolution operator. In this way a closed set of equations for the density correlation function and the memory function is obtained. The theory predicts an ergodicity breaking transition similar to that predicted by the mode-coupling theory, but at a higher density.

Hydrodynamic Inverse Faraday Effect in Two Dimensional Electron Liquid

description: We show that a small conducting object, such as a nanosphere or a nanoring, embedded into or placed in the vicinity of the two-dimensional electron liquid (2DEL) and subjected to a circularly polarized electromagnetic radiation induces ``twisted'' plasmonic oscillations in the adjacent 2DEL. The oscillations are rectified due to the hydrodynamic nonlinearities leading to the helicity sensitive circular dc current and to a magnetic moment. This hydrodynamic inverse Faraday effect (HIFE) can be observed at room temperature in different materials. The HIFE is dramatically enhanced in a periodic array of the nanospheres forming a resonant plasmonic coupler. Such a coupler exposed to a circularly polarized wave converts the entire 2DEL into a vortex state. Hence, the twisted plasmonic modes support resonant plasmonic-enhanced gate-tunable optical magnetization. Due to the interference of the plasmonic and Drude contributions, the resonances have an asymmetric Fano-like shape. These resonances present a signature of the 2DEL properties not affected by contacts and interconnects and, therefore, providing the most accurate information about the 2DEL properties. In particular, the widths of the resonances encode direct information about the momentum relaxation time and viscosity of the 2DEL.

description: We study the action and geometry of P-vortices, discriminating between the percolating and finite clusters. We also discuss the interrelation of the monopoles and P-vortices. To define P-vortices we use both the direct maximal center projection and indirect maximal center projection. We find, in particular, that the action density of the P-vortices in short clusters is substantially higher than in the percolating cluster. The surface of the percolating cluster appears random at short distances, with action density depending on the shape.

description: The energy partitioning during activation and relaxation events under steady-state conditions for a Brownian particle driven by multiple thermal reservoirs of different local temperatures is investigated. Specifically, we apply the formalism derived in a previous article [G. T. Craven and A. Nitzan, J. Chem. Phys. 148, 044101 (2018)] to examine the thermal transport properties of two sub-ensembles of Brownian processes, distinguished at any given time by the specification that all the trajectories in each group have, at that time, energy either above (upside) or below (downside) a preselected energy threshold. Dynamical properties describing energy accumulation and release during activation/relaxation events and relations for upside/downside energy partitioning between thermal reservoirs are derived. The implications for heat transport induced by upside and downside events are discussed.

Consequently, the model can be used to study the functionality of different neuronal cultures and simulate the network response to external stimuli.

description: With the development of blockchain technology, smart contracts have become an important component of blockchain applications. Despite their crucial role, the development of smart contracts may introduce vulnerabilities and potentially lead to severe consequences, such as financial losses. Meanwhile, large language models, represented by ChatGPT, have gained great attentions, showcasing great capabilities in code analysis tasks. In this paper, we presented an empirical study to investigate the performance of ChatGPT in identifying smart contract vulnerabilities. Initially, we evaluated ChatGPT's effectiveness using a publicly available smart contract dataset. Our findings discover that while ChatGPT achieves a high recall rate, its precision in pinpointing smart contract vulnerabilities is limited. Furthermore, ChatGPT's performance varies when detecting different vulnerability types. We delved into the root causes for the false positives generated by ChatGPT, and categorized them into four groups. Second, by comparing ChatGPT with other state-of-the-art smart contract vulnerability detection tools, we found that ChatGPT's F-score is lower than others for 3 out of the 7 vulnerabilities. In the case of the remaining 4 vulnerabilities, ChatGPT exhibits a slight advantage over these tools. Finally, we analyzed the limitation of ChatGPT in smart contract vulnerability detection, revealing that the robustness of ChatGPT in this field needs to be improved from two aspects: its uncertainty in answering questions; and the limited length of the detected code. In general, our research provides insights into the strengths and weaknesses of employing large language models, specifically ChatGPT, for the detection of smart contract vulnerabilities.

Si caratterizza per un approccio interdisciplinare, integrato alle questioni ambientali e aperto alla democratizzazione dei processi conoscitivi: contrastato già negli anni ‘80, offre spunti di estrema attualità per affrontare la pretesa “crisi” climatica che oggi ci investe. L’articolo ne traccia una possibile genealogia nel pensiero del fisico Marcello Cini e nell’attività di piano dell’urbanista Italo Insolera, alla luce delle considerazioni di Pierre Bourdieu sull’emancipazione dai saperi dominanti. In Italy, along the 1970s, a critical conceptual frame, arising from an interdisciplinary approach, integrated with environmental issues and engaged for the democratization of cognitive processes, figures out new epistemological perspectives of scientific research and new schemes for land management. Soon counteracted in the 1980s, it offers today significant topics to face the so-called “Climate Crisis” affecting our times. The article focuses the eventual paths of its genealogy, addressing the theory of the physicist Marcello Cini and the spatial planning activity of the planner Italo Insolera, in the light of Pierre Bourdieu’s considerations on the emancipatory processes from dominant knowledge.

description: The development of pork prices has been analysed since the 1920s. Well known economic concepts such as Hanau’s pork cycle or Ezekiel’s cobweb theorem are based on the empirical analysis of pork markets. We analyze whether pork price developments in different countries have become more synchronised over time. In a first stage of our analysis, annual pork price data collected by the FAO reveals much heterogeneity of pork price developments across countries. However, for some groups of countries the observed price patterns are very similar or even identical. This is especially the case for neighbouring countries with integrated pork markets, such as the members of the European Union (EU). We then compare pork price developments in Germany and the USA based on 36 years of monthly producer prices for slaughter pigs. Since the middle of the 1990s cyclical pork price movements in the USA and Germany have become increasingly synchronous. We attribute this to two developments: the fact that the USA has become a large net exporter of pork over this period, and policy reform in the EU that has strengthened the link between international and EU feed prices.
Hidden order and beyond: an experimental-theoretical overview of the multifaceted behavior of URu$_2$Si$_2$

description: This Topical Review describes the multitude of unconventional behaviors in the hidden order, heavy fermion, antiferromagnetic and superconducting phases of the intermetallic compound URu$_2$Si$_2$ when tuned with pressure, magnetic field, and substitutions for all three elements. Such `perturbations' result in a variety of new phases beyond the mysterious hidden order that are only now being slowly understood through a series of state-of-the-science experimentation, along with an array of novel theoretical approaches. Despite all these efforts spanning more than 30 years, hidden order (HO) remains puzzling and non-clarified, and the search continues in 2019 into a fourth decade for its final resolution. Here we attempt to update the present situation of URu$_2$Si$_2$ importing the latest experimental results and theoretical proposals. First, let us consider the pristine compound as a function of temperature and report the recent measurements and models relating to its heavy Fermi liquid crossover, its HO and superconductivity (SC). Recent experiments and theories are surmized that address four-fold symmetry breaking (or nematicity), Isingness and unconventional excitation modes. Second, we review the pressure dependence of URu$_2$Si$_2$ and its transformation to antiferromagnetic long-range order. Next we confront the dramatic high magnetic-field phases requiring fields above 40 T. And finally, we attempt to answer how does random substitutions of other $5f$ elements for U, and $3d$, $4d$, and $5d$ elements for Ru, and even P for Si affect and transform the HO. Commensurately, recent theoretical models are summarized and then related to the intriguing experimental behavior.

description: L’expertise scientifique collective « Agriculture et sécheresse » pilotée par l’INRA en 2006 a mis en évidence le manque de données quantitatives sur l’impact économique d’une sécheresse en France. En réponse, des économistes de l’INRA ont élaboré un couplage original entre le modèle agronomique STICS développé par l’INRA et un modèle de calcul économique. Cette étude a eu pour but d’estimer le coût des épisodes de sécheresse pour un agriculteur représentatif de la région Midi-Pyrénées et de déterminer si ses décisions de court ou de long terme permettent d’atténuer de manière significative ce coût. Les résultats obtenus indiquent qu’à court terme le coût induit par la sécheresse peut être élevé. A long terme, c’est-à-dire dans le cas où les systèmes de culture peuvent être modifiés par l’agriculteur, le coût induit de la sécheresse est atténué de manière sensible par ces capacités d’adaptation supplémentaires. De plus, la mise en place de mécanismes d’alerte sécheresse précoce peut être bénéfique pour les agriculteurs en Midi-Pyrénées.

They actually show that given any $1^+$-factor $F$ (a spanning subgraph of $G$ such that its vertices have degree at least 1) and an arbitrary edge $e$ of $G$, there exists a perfect matching $M$ of $G$ containing $e$ such that $G\setminus (F\cup M)$ is bipartite. This is a step closer to comprehend better the Fan--Raspaud Conjecture and eventually the Berge--Fulkerson Conjecture. The $S_4$-Conjecture, now a theorem, is also the weakest assertion in a series of three conjectures made by Mazzuoccolo in 2013, with the next stronger statement being: there exist two perfect matchings of $G$ such that the complement of their union is an acyclic subgraph of $G$. Unfortunately, this conjecture is not true: Jin, Steffen, and Mazzuoccolo later showed that there exists a counterexample admitting 2-cuts. Here we show that, despite of this, every cyclically 3-edge-connected cubic graph satisfies this second conjecture.

description: How do we explain variation in judicial assertiveness towards politically powerful militaries? This article argues that the judiciary’s willingness to assert itself against the military is contingent upon the type of military prerogative being challenged. Focusing on Pakistan, I find that courts are more willing to contest military prerogatives connected to the military’s political authority, than prerogatives connected to its institutional autonomy. This selective assertiveness is strategic, as concerns about military retaliation against the judiciary are more likely to outweigh judicial preferences, on questions of the military’s institutional autonomy than on questions of the military’s political authority. I test this hypothesis using an original dataset of 720 high court and supreme court judgments pertaining to military prerogatives from Pakistan. I then discuss a sample of judgments selected from the dataset to demonstrate how variation in judicial assertiveness is guided primarily by strategic concerns about the likelihood of military retaliation against the judiciary. In studying the interactions between the judiciary and the military in Pakistan, the article provides a new perspective on the sources of judicial assertiveness and restraint, and the role the judiciary can play in bringing militaries under civilian control in authoritarian and post-authoritarian states.

description: Nel 1845 Engels finisce di scrivere “La situazione della classe operaia in Inghilterra”. Un libro che, riletto oggi, evidenzia tutta la sua complessità e ricchezza laddove l’autore tenta di rispondere a domande che ancora oggi rimangono centrali per tutti coloro che fanno parte di ciò che in questo articolo proverò a chiamare urban studies. Difficile in questo senso, giudicare il libro di Engels: a quale sguardo disciplinare “ingabbiarlo”? In questi ultimi 175 anni saranno infatti tanti i ricercatori e le ricercatrici, con sguardi disciplinari differenti, che ripartiranno dalle questioni sollevate dallo studioso tedesco per descrivere e analizzare il processo di nascita delle città moderne; ma saranno tanti anche i romanzieri che prenderanno ispirazione dal testo di Engels, a dimostrazione di come la sua opera fu sempre percepita come un prodotto scientifico costruito su dispositivi narrativi difficilmente classificabile nel gioco attuale dei settori scientifici disciplinari. Ma cosa vedeva Engels quando passeggiava lungo i viali di Manchester? Rispondere a questa domanda ci permette di rileggere gli studi urbani e studiarne la debolezza/solidità della loro base epistemologica. In 1845 Engels finished writing “The condition of the working class in England”. A book that, re-read today, highlights all its complexity and richness where the author tries to answer questions that still remain central to all those who are part of what in this article I will try to call urban studies. In this sense, it is difficult to judge Engels’ book: which disciplinary view to “cage” it? In the last 175 years, in fact, there will be many researchers and researchers, with different disciplinary looks, who will start from the questions raised by the German scholar to describe and analyze the birth process of modern cities; but there will be many novelists who will take inspiration from Engels' text, demonstrating how his work was always perceived as a scientific product built on narrative devices difficult to classify in the current game of the disciplinary scientific sectors. But what did Engels see when he walked along Manchester avenues? Answering this question allows us to reread urban studies and study the weakness / solidity of their epistemological basis.

description: La geografia urbana si confronta da sempre con la scuola di Chicago, ma più di recente la scuola di Los Angeles ha introdotto nuovi elementi di riflessione, rafforzando peraltro la componente più geografica. Dal confronto tra le due scuole, e dalle critiche mosse negli ultimi venti anni alla seconda, emergono spunti di grande interesse. Occorre capire che direzione stiano prendendo gli studi urbani dopo le lezioni di Los Angeles, grazie anche alla nascita del comparative urbanism. A questo quadro già complesso va affiancato un ragionamento sulla situazione italiana. Dopo decenni di rapporti con le teorie francesi e tedesche, negli ultimi anni anche la geografia urbana italiana ha cominciato a confrontarsi con gli urban studies anglosassoni, pur rendendosi conto che certe affermazioni non potevano essere facilmente applicate alla situazione nostrana. Quali possono essere dunque i presupposti per costruire un vero filone di geografia urbana critica in Italia? Urban geography has always dealt with the Chicago school, but more recently the Los Angeles school has introduced new elements of reflection and strengthened the more geographical component. In the comparison between the two schools, and in the criticisms made in the last twenty years to the second, there are lessons to be learnt. Comparative urbanism urges us to question which direction urban studies are taking after Los Angeles. This already complex framework must be considered in the peculiar Italian situation. After decades of relations with French and German theories, in recent years Italian urban geography has also begun to confront Anglo-Saxon urban studies, while realizing that certain statements could not be easily applied to the Italian situation. What can be the prerequisites for building a real strand of critical urban geography in Italy, then?

description: An abrupt Mott metal-insulator transition (MIT) rather than the continuous Hubbard MIT near a critical on-site Coulomb energy U/U_c=1 is observed for the first time in VO_2, a strongly correlated material, by inducing holes of about 0.018% into the conduction band. As a result, a discontinuous jump of the density of states on the Fermi surface is observed and inhomogeneity inevitably occurs. The gate effect in fabricated transistors is clear evidence that the abrupt MIT is induced by the excitation of holes.

description: Using random matrix technique we determine an exact relation between the eigenvalue spectrum of the covariance matrix and of its estimator. This relation can be used in practice to compute eigenvalue invariants of the covariance (correlation) matrix. Results can be applied in various problems where one experimentally estimates correlations in a system with many degrees of freedom, like in statistical physics, lattice measurements of field theory, genetics, quantitative finance and other applications of multivariate statistics.

Upside/Downside statistical mechanics of nonequilibrium Brownian motion. I. Distributions, moments, and correlation functions of a free particle

description: Statistical properties of Brownian motion that arise by analyzing, separately, trajectories over which the system energy increases (upside) or decreases (downside) with respect to a threshold energy level, are derived. This selective analysis is applied to examine transport properties of a nonequilibrium Brownian process that is coupled to multiple thermal sources characterized by different temperatures. Distributions, moments, and correlation functions of a free particle that occur during upside and downside events are investigated for energy activation and energy relaxation processes, and also for positive and negative energy fluctuations from the average energy. The presented results are sufficiently general and can be applied without modification to standard Brownian motion. This article focuses on the mathematical basis of this selective analysis. In subsequent articles in this series we apply this general formalism to processes in which heat transfer between thermal reservoirs is mediated by activated rate processes that take place in a system bridging them.
Authoritarian diasporas in Indonesia and the Philippines: comparative perspectives on elite survival and defection

description: The article compares the political trajectories of authoritarian diasporas in Indonesia and the Philippines, namely the subset of former regime officials that disperse across the electoral space after a regime transition. The main finding is that after the Suharto and Marcos dictatorships collapsed in 1998 and 1986 respectively, Indonesia's authoritarian successor party (ASP) fared better than the ASP in the Philippines. However, the authoritarian diaspora did better in the Philippines than in Indonesia. Engaging with existing scholarship on authoritarian successor parties and authoritarian diasporas, the article argues that the two variables shaping defection calculi are the prevailing levels of party institutionalization of both the authoritarian successor party and alternative parties as well as the type of reversionary clientelistic network available to elites in post-transition politics.

description: La preponderanza delle economie urbane, fino alle estremizzazioni della finanziarizzazione dello spazio delle città, limitano fortemente la capcità di leggere e interpretare la complessità e l’eterogeneità degli spazi che abitiamo. L’articolo propone un rapido excursus dei recenti contributi allo studio dei processi di riorganizzazione della dimensione rurale che hanno proposto, in regioni diverse, paradigmi interpretativi coerenti delle trasformazioni agricole, con inedite possibilità di stabilire relazioni fra processi lontani dagli sguardi privilegiati dagli studi urbani convenzionali. Vengono quindi messi a confronto due testi ormai storici, la Storia del paesaggio agrario italiano, pubblicata da Emilio Sereni nel 1961, e il capitolo dedicato all’aggiornamento di un precedente lavoro sul villaggio di Kaixiangong, pubblicato da Fei Xiaotong nel 1957 nel volume Rural development in China. Prospect and retrospect, con una riflessione finale sulle rispettive metodologie di ricerca.

description: The aim of this article is to give an overall picture of the impact of the economic crisis by comparing one of the leading participants of world economy (EU-27) with Hungary and its neighbouring country, Slovakia. On the basis of the results we outline the tendencies and changes to be expected in Hungary by evaluating our most important labour market indicators. According to the macroeconomic indicators, the global economic crisis had a great impact in the Member States of the European Union including the Slovak Republic and Hungary.
