Typical Yet Unlikely and Normally Abnormal: The Intuition Behind High-Dimensional Statistics

description: Normality, in the colloquial sense, has historically been considered an aspirational trait, synonymous with ideality. The arithmetic average and, by extension, statistics including linear regression coefficients, have often been used to characterize normality, and are often used as a way to summarize samples and identify outliers. We provide intuition behind the behavior of such statistics in high dimensions, and demonstrate that even for datasets with a relatively low number of dimensions, data start to exhibit a number of peculiarities which become severe as the number of dimensions increases. Whilst our main goal is to familiarize researchers with these peculiarities, we also show that normality can be better characterized with `typicality', an information theoretic concept relating to entropy. An application of typicality to both synthetic and real-world data concerning political values reveals that in multi-dimensional space, to be `normal' is actually to be atypical. We briefly explore the ramifications for outlier detection, demonstrating how typicality, in contrast with the popular Mahalanobis distance, represents a viable method for outlier detection.

description: Obiettivo fissato per la ricerca è indagare la possibilità di riutilizzo, in un comparto come quello dell’edilizia, delle plastiche miste post-consumo, provenienti dalla raccolta differenziata, che attualmente sono soggette unicamente a smaltimento, con contributo ambientale, quindi con dispendio di soldi della comunità. La tesi perviene alla sperimentazione e prototipazione di un nuovo componente edilizio ecosostenibile realizzato con l’impiego delle plastiche miste post-consumo e materiali ceramici, che assume forma di un pannello sandwich. Inoltre nell’ambito della tesi viene progettato un sistema di applicazione dello stesso, iscrivibile al novero delle cosiddette “facciate ventilate”. Il risultato originale della ricerca è strettamente legato alla possibilità, una volta conformato il suddetto sistema edilizio, terminato nell’ambito della tesi, e successivamente eseguita l’industrializzazione del prodotto, di trovare una collocazione sul mercato alle ingenti frazioni che esistono di plastiche miste post-consumo, derivate da Raccolta Differenziata, con conseguente valorizzazione e valido apporto economico e ambientale. L’elemento di originalità della tesi è stata anche riconosciuta all’esterno dell’ambito universitario, infatti il sistema sviluppato nell’ambito della stessa, ha iniziato l’iter per conseguire il brevetto.

description: Haliplus (Paraliaphlus) borealis LeConte, 1850 Haliplus borealis was reported from New Brunswick and Nova Scotia by Brigham (1996). We have not found specimens of this species in any reference collection, nor published records of the species from either province. It is not listed from either province in any of the published references provided by Brigham (1996) for this species, however, Brigham (1996) did include records from unpublished material in his checklist. Brigham passed away in 1996 and consequently there is no way of checking the source of this report. Consequently we provisionally retain this species in the faunal lists of New Brunswick and Nova Scotia. Its presence in the region should be further investigated and confirmed. Kenner (2008) suggests that this species should be re-assigned to the subgenus Haliplus (s. str.) based on the asymmetry of the sutural margin.

description: GIS enables the display of the territorial organisation in a tourist framework,
as well as its connections with the socio-economic system in the area of lake Bolsena. It features as the most mature and developed tourism in the area of Viterbo Province, shown also by the attention paid by foreigners. However, even if in the last decade this area has been experiencing a growth in tourist activities, a decrease in population is also occurring. As for the tourist flow, some kind of growth seems difficult to achieve. Most probably, tourism here could be extended into a wider system, by trying to emphasize the archaeological resources of minor sites.

Dans la zone du lac de Bolsena, le GIS permet de comprendre l’organisation du territoire, d’un point de vue touristique, et ses liens avec
le système socio-économique. Cette zone présente le tourisme le plus
mûr et le plus développé de la province de Viterbe, comme le confirme
aussi le fait qu’elle est bien appréciée par les étrangers. Cependant, même si elle a connu durant les dix dernières années un développement
de ses activités touristiques, elle a aussi enregistré une diminution de
population. Comme pour le flux touristique, certains types de croissance
semblent avoir du mal à s’accomplir totalement. Il y a fort à parier
que là, le tourisme pourrait élargir davantage son rayon d’action, à condition d’essayer de mettre en valeur les ressources archéologiques de
sites mineurs.

In this paper we consider solutions for which at least one of the Killing spinors generates a timelike Killing vector. We obtain coordinate transformations which considerably simplify the solutions, and in a number of cases, we obtain explicitly some additional Killing vectors which were hidden in the original analysis.

description: The Randall-Sundrum model with a small curvature is considered in which five-dimensional Planck scale lies in the TeV region, and a spectrum of Kaluza-Klein gravitons reminds that in one flat extra dimension. The cross sections for interactions of ultra-high energy cosmic neutrinos with nucleons are calculated. It is shown that effects related with massive graviton excitations can be detected in deeply penetrating inclined air showers induced by these neutrinos. The expected number of air showers at the Auger Observatory is estimated as a function of two parameters of the model.

Spin Spiral and Topological Hall Effect in a Metamagnet Fe$_{3}$Ga$_{4}$

Year: 2021
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: A new mechanism for Topological Hall Effect (THE) was recently proposed for the spiral magnet YMn$_{6}$Sn$_{6},$ which requires transverse conical spiral (TCS) magnetism, induced by external magnetic field, combined with thermally excite helical spiral magnons. In principle, this mechanism should be applicable to other itinerant spiral magnets as well. In this paper, we show that another metamagnetic compound, Fe$_{3}$Ga$_{4}$, where THE was observed experimentally before, in one of its phases satisfies this condition, and the proposed theory of thermal-fluctuation driven THE is quantitatively consistent with the experiment. This finding suggests that this mechanism is indeed rather universal, and the effect may have been observed in other compounds before, but overlooked.

description: Understanding strongly correlated quantum materials, such as high $T_\textrm{c}$ superconductors, iron-based superconductors, and twisted bilayer graphene systems, remains to be one of the outstanding challenges in condensed matter physics. Quantum simulation with ultra-cold atoms in particular optical lattices, which provide orbital degrees of freedom, is a powerful tool to contribute new insights to this endeavor. Here, we report the experimental realization of an unconventional Bose-Einstein condensate of $^{87}$Rb atoms populating degenerate $p$-orbitals in a triangular optical lattice, exhibiting remarkably long coherence times. Using time-of-flight spectroscopy, we observe that this state spontaneously breaks the rotational symmetry and its momentum spectrum agrees with the theoretically predicted coexistence of exotic stripe and loop current orders. Like certain strongly correlated electronic systems with intertwined orders, as high-$T_\textrm{c}$ cuprate superconductors, twisted bilayer graphene, and the recently discovered chiral density-wave state in kagome superconductors $\textrm{AV}_3 \textrm{Sb}_5$ (A=K, Rb, Cs), the newly demonstrated quantum state, in spite of its markedly different energy scale and the bosonic quantum statistics, exhibits multiple symmetry breakings at ultralow temperatures. These findings hold the potential to enhance our comprehension of the fundamental physics governing these intricate quantum materials.

description: We study the influence of surface Andreev bound states in d-wave superconductors on the Bean-Livingston surface barrier for entry of a vortex line into a strongly type-II superconductor. Starting from Eilenberger theory we derive a generalization of London theory to incorporate the anomalous surface currents arising from the Andreev bound states. This allows us to find an analytical expression for the modification of the Bean-Livingston barrier in terms of a single parameter describing the influence of the Andreev bound states. We find that the field of first vortex entry is significantly enhanced. Also, the depinning field for vortices near the surface is renormalized. Both effects are temperature dependent and depend on the orientation of the surface relative to the d-wave gap function.

description: Meta-Learning aims to speed up the learning process on new tasks by acquiring useful inductive biases from datasets of related learning tasks. While, in practice, the number of related tasks available is often small, most of the existing approaches assume an abundance of tasks; making them unrealistic and prone to overfitting. A central question in the meta-learning literature is how to regularize to ensure generalization to unseen tasks. In this work, we provide a theoretical analysis using the PAC-Bayesian theory and present a generalization bound for meta-learning, which was first derived by Rothfuss et al. (2021a). Crucially, the bound allows us to derive the closed form of the optimal hyper-posterior, referred to as PACOH, which leads to the best performance guarantees. We provide a theoretical analysis and empirical case study under which conditions and to what extent these guarantees for meta-learning improve upon PAC-Bayesian per-task learning bounds. The closed-form PACOH inspires a practical meta-learning approach that avoids the reliance on bi-level optimization, giving rise to a stochastic optimization problem that is amenable to standard variational methods that scale well. Our experiments show that, when instantiating the PACOH with Gaussian processes and Bayesian Neural Networks models, the resulting methods are more scalable, and yield state-of-the-art performance, both in terms of predictive accuracy and the quality of uncertainty estimates.

Scopo di questo studio è  valutare le risposte fisiologiche di una microalga verde, Chlorella sorokiniana, in seguito ad esposizione a due metalli pesanti: piombo e cadmio. Questo organismo, per la sua facilità di coltivazione in laboratorio, può essere considerato un buon  organismo modello. È stata, inoltre, verificata l’eventuale correlazione tra stress da metalli pesanti e metabolismo dello zolfo.

description: No imaging apparatus can produce perfect images: spatial resolution is limited by the Rayleigh diffraction bound that is a consequence of the imager's finite spatial extent. We show some N-photon strategies that permit resolution of details that are smaller than this bound, attaining either a 1/sqrt(N) enhancement (standard quantum limit) or a 1/N enhancement (Heisenberg limit) over standard techniques. In the incoherent imaging regime, the methods presented are loss resistant, because they can be implemented with classical-state light sources. Our results may be of importance in many applications: microscopy, telescopy, lithography, metrology, etc.

description: Real-time nonequilibrium Green functions (NEGF) have been very successful to simulate the dynamics of correlated many-particle systems far from equilibrium. However, NEGF simulations are computationally expensive since the effort scales cubically with the simulation duration. Recently we have introduced the G1--G2 scheme that allows for a dramatic reduction to time-linear scaling [Schlünzen, Phys. Rev. Lett. 124, 076601 (2020); Joost et al., Phys. Rev. B 101, 245101 (2020)]. Here we tackle another problem: the rapid growth of the computational effort with the system size. In many situations where the system of interest is coupled to a bath, to electric contacts or similar macroscopic systems for which a microscopic resolution of the electronic properties is not necessary, efficient simplifications are possible. This is achieved by the introduction of an embedding selfenergy -- a concept that has been successful in standard NEGF simulations. Here, we demonstrate how the embedding concept can be introduced into the G1--G2 scheme, allowing us to drastically accelerate NEGF embedding simulations. The approach is compatible with all advanced selfenergies that can be represented by the G1--G2 scheme [as described in Joost et al., Phys. Rev. B 105, 165155 (2022)] and retains the memory-less structure of the equations and their time linear scaling. As a numerical illustration we investigate the charge transfer between a Hubbard nanocluster and an additional site which is of relevance for the neutralization of ions in matter.

Valutazione di tollerabilità, profilo nutrizionale e stress ossidativo di organismi acquatici  alimentati con diete alternative a base di vegetali
Creators: name: Ioviero, Marianna
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: Lo scopo della ricerca mira a testare diete alternative per l’alimentazione diretta e indiretta di specie marine, sostituendo, in parte o completamente, i mangimi tradizionali con vegetali che hanno un basso costo, possono essere recuperati da scarti di produzione per l’alimentazione umana e sono facilmente reperibili sul mercato. Inoltre, l’uso dei vegetali, ricchi in antiossidanti, potrebbe rivelarsi una soluzione valida e naturale per aumentare la resistenza agli stress, e dunque alle malattie, e per ridurre la percentuale delle farine di pesce presenti nei mangimi tradizionali che provocano un enorme impatto sugli stock ittici naturali.
Lo spinacio, il pomodoro, l’origano, il cranberry, l’oliva e l’uva sono stati aggiunti o sostituiti ai mangimi tradizionali per l’alimentazione di organismi marini appartenenti a diversi livelli della catena trofica e a diversi phylum marini: crostacei (Artemia salina L.), molluschi (Mytilus galloprovincialis Lmk.) e pesci (Sparus aurata L.).
La somministrazione delle diete test ai livelli inferiori della catena trofica,permette di ipotizzare un notevole abbattimento degli elevati costi di approvvigionamento e produzione di organismi vivi/freschi per l’alimentazione degli avannotti e dei riproduttori, noti come gli stadi di sviluppo più delicati, per cui è necessaria una dieta con specifiche caratteristiche nutrizionali. Inoltre l’utilizzo dei vegetali permette di ipotizzare colture in continuo dello zooplancton attivando l’intero ciclo vitale degli organismi e, dunque, riducendo al minimo l’approvvigionamento in natura.

description: We present a search for the decay B+ -> tau+ nu using 383x10^6 BBbar pairs collected at the Y(4S) resonance with the BABAR detector at the SLAC PEP-II B-Factory. A sample of events with one reconstructed semileptonic B decay (B- -> D0 l nu X)) is selected, and in the recoil a search for B+ -> tau+ nu is performed. The tau is identified in the following channels: tau+ -> e nu nubar, tau+ -> mu nu nubar, tau+ -> pi+ nu, and tau+ -> pi+ pi0 nu. We measure a branching fraction of B(B+ -> tau+ nu)=(0.9 +- 0.6(stat.) +- 0.1(syst.)) x 10^-4. In the absence of a significant signal, we calculate an upper limit at the 90% confidence level of B(B+ -> tau+ nu) < 1.7 x 10^-4. We calculate the product of the B meson decay constant f_B and |V_ub| to be f_B x |V_ub| = (7.2^{+2.0}_{-2.8}(stat.) +- 0.2 (syst.)) x 10^-4 GeV.

description: A periodically driven open three-level Dicke model is realized by resonantly shaking the pump field in an atom-cavity system. As an unambiguous signature, we demonstrate the emergence of a dynamical phase, in which the atoms periodically localize between the antinodes of the pump lattice, associated with an oscillating net momentum along the pump axis. We observe this dynamical phase through the periodic switching of the relative phase between the pump and cavity fields at a small fraction of the driving frequency, suggesting that it exhibits a time crystalline character.

description: Il 9 settembre scorso, nell’ambito del Congresso Geografico Nazionale organizzato a Firenze dall’Associazione dei Geografi Italiani (9-12 settembre), si è tenuto un Forum dei Giovani Studiosi avente per tema “Esperienze e metodi di ricerca in Geografia”, coordinato da F. Farinelli e G. Scaramellini. Il Forum, nell’intento organizzativo, aveva l’obiettivo di offrire ai giovani uno spazio di dialogo e confronto su riferimenti epistemologici, metodi, organizzazione del piano di ricerca (non solo di dottorato), contenuti e risultati, sulle problematiche di tipo metodologico e sulla rilevanza della ricerca sul campo. Si tratta di una iniziativa di rilievo almeno per due motivi: è la prima nel suo genere realizzata in un Congresso Nazionale ed è stata promossa “dal basso”, grazie all’azione del gruppo “Giovani Geografi”

Cell migration in anisotropic media

Publisher: name: Università degli Studi di Napoli Federico II

description: A wide range of basic cellular process depends on cell motility that is fundamental for all eukaryotes. The ability of cells to migrate, adhere, and change shape requires most of the time external signals, although few cells respond primarily to internal cues. One of the most interesting and important response to external stimuli is chemotaxis. Chemotaxis, the directional movement of cells according to a concentration gradient of chemicals, is implicated in physiologically relevant phenomena such as inflammatory response, homeostatic circulation, and development and several disorders including infectious and allergic diseases, wound healing, angiogenesis, atherosclerosis, and tumor metastasis. However, despite the ubiquity and importance of chemotaxis, it remains a difficult process to study in vitro. The work carried out in this thesis present a novel chemotaxis assay in 3-D collagen gels in a direct-viewing chamber. Chemotaxis studies require a way to deliver chemicals to cells in a controlled gradient because cells need to be able to sense an increase in concentration of chemokine to direct their motion. In this chemotaxis assay a chemoattractant concentration gradient in the collagen gel sample seeded with cells is generated by diffusion trough a porous membrane. The diffusion process is monitored by fluorescence microscopy of FITC labelled dextran. Cell motion under the action of the chemoattractant gradient is followed by time-lapse video microscopy. Cell tracking is performed off-line by image analysis and the results are expressed in terms of a chemotactic index and velocity. The assay has been tested by using human neutrophils as a model.

Transient Information Adaptation of Artificial Intelligence: Towards Sustainable Data Processes in Complex Projects

description: Large scale projects increasingly operate in complicated settings whilst drawing on an array of complex data-points, which require precise analysis for accurate control and interventions to mitigate possible project failure. Coupled with a growing tendency to rely on new information systems and processes in change projects, 90% of megaprojects globally fail to achieve their planned objectives. Renewed interest in the concept of Artificial Intelligence (AI) against a backdrop of disruptive technological innovations, seeks to enhance project managers cognitive capacity through the project lifecycle and enhance project excellence. However, despite growing interest there remains limited empirical insights on project managers ability to leverage AI for cognitive load enhancement in complex settings. As such this research adopts an exploratory sequential linear mixed methods approach to address unresolved empirical issues on transient adaptations of AI in complex projects, and the impact on cognitive load enhancement. Initial thematic findings from semi-structured interviews with domain experts, suggest that in order to leverage AI technologies and processes for sustainable cognitive load enhancement with complex data over time, project managers require improved knowledge and access to relevant technologies that mediate data processes in complex projects, but equally reflect application across different project phases. These initial findings support further hypothesis testing through a larger quantitative study incorporating structural equation modelling to examine the relationship between artificial intelligence and project managers cognitive load with project data in complex contexts.

description: The study of the formation of molecular hydrogen on low temperature surfaces is of interest both because it allows to explore elementary steps in the heterogeneous catalysis of a simple molecule and because of the applications in astrochemistry. Here we report results of experiments of molecular hydrogen formation on amorphous silicate surfaces using temperature-programmed desorption (TPD). In these experiments beams of H and D atoms are irradiated on the surface of an amorphous silicate sample. The desorption rate of HD molecules is monitored using a mass spectrometer during a subsequent TPD run. The results are analyzed using rate equations and the activation energies of the processes leading to molecular hydrogen formation are obtained from the TPD data. We show that a model based on a single isotope provides the correct results for the activation energies for diffusion and desorption of H atoms. These results can thus be used to evaluate the formation rate of H_2 on dust grains under the actual conditions present in interstellar clouds.

description: Calculations are carried out for the scattering of heavy rare gas atoms with surfaces using a recently developed classical theory that can track particles trapped in the physisorption potential well and follow them until ultimate desorption. Comparisons are made with recent experimental data for xenon scattering from molten gallium and indium, systems for which the rare gas is heavier than the surface atoms. The good agreement with the data obtained for both time-of-flight energy-resolved spectra and for total scattered angular distributions yields an estimate of the physisorption well depths for the two systems.
