description: For the first time high-resolution optical spectroscopy of the variable star V2324Cyg associated with the IR-source IRAS20572+4919 is made. More than 200 absorption features (mostly FeII, TiII, CrII, YII, BaII, and YII) are identified within the wavelength interval 4549-7880AA. The spectral type and rotation velocity of the star are found to be F0III and Vsini=69km/s, respectively. HI and NaID lines have complex PCyg-type profiles with an emission component. Neither systematic trend of radial velocity Vr with line depth Ro nor temporal variability of Vr have been found. We determined the average heliocentric radial velocity Vr=-16.8\pm 0.6km/s. The radial velocities inferred from the cores of the absorption components of the H$β$ and NaI wind lines vary from -140 to -225km/s (and the expansion velocities of the corresponding layers, from about 120 to 210km/s). The maximum expansion velocity is found for the blue component of the split H$α$ absorption: 450km/s for December 12, 1995. The model atmospheres method is used to determine the star's parameters: Teff=7500K, log g=2.0, $ξ_t$=6.0km/s, and metallicity, which is equal to the solar value. The main peculiarity of the chemical abundances pattern is the overabundance of lithium and sodium. The results cast some doubt on the classification of V2324Cyg as a post-AGB star.

The trigger of the AGB superwind: the importance of carbon

description: The driving mechanism of the AGB superwind has become controversial in recent years. The efficacy of dust-driven mass loss has been queried. Spitzer observation of AGB stars in Local Group Galaxies show the surprising result that at low metallicity, AGB mass loss occurs at low luminosity, possibly lower than in the Galaxy, but only for carbon-rich stars. Oxygen-rich stars in the Galaxy and in lower metallicity galaxies have similar mass-loss rates only at high luminosities. To explain this dichotomy, we propose that the superwind has a dual trigger. The superwind starts either when sufficient excess carbon builds up for efficient formation of carbonaceous dust (which we propose occurs when $X_{\rm CO} = \rm (C - O)/ O_\odot = 0.1$), or when the luminosity reaches a value sufficient for a silicate-dust-driven wind (proposed at $L = 10^4 Z^{-4/3} \rm L_\odot)$. We show that this dual trigger fits the current observational constraints: the luminosity at which the superwind begins, and the predominance of carbon superwind star at low metallicity. We use stellar evolution models to check the consistency of our explanations and present detailed predictions of the luminosities at which the superwind is triggered for different metallicities and initial stellar masses.

The simulations are targeted towards an experiment previously conducted at CalTech (Bellan, P. M. and J. F. Hansen, Phys. Plasmas, 5, 1991 (1998)) which aimed at simulating Solar prominence eruptions in the laboratory. The plasma dynamics is described by ideal MHD using different models for the evolution of the mass density. Key features of the reported experimental observations like pinching of the current loop, its expansion and distortion into helical shape are reproduced in the numerical simulations. Details of the final structure depend on the choice of a specific model for the mass density.

description: In the previous four decades, a two-coil mutual inductance (MI) technique has been widely employed in characterizing magnetic penetration depth, $λ$, of superconducting films. However, the conventional methods used to obtain $λ$ are not applicable to small-sized films with common shapes, which limits the application of the MI technique in superconductivity research. Here, we first employed the fast wavelet collocation (FWC) method to a two-coil system and then proposed the possibility of directly obtaining the absolute $λ$ of polygonal superconducting films with arbitrary sizes. To verify its accuracy and advantages, we extracted the $λ$ values of square NbN films with different sizes using the FWC and conventional flux leakage subtraction (FLS) methods. Notably, the FLS method fails for a $5\times 5 \, \rm mm^2$ film, which is attributed to the significant current peak at the film edge. In contrast, the absolute $λ$ extracted using the FWC method was independent of the film size. Finally, we established the applicability of the FWC method to large coil spacings, which may pave the way for integrating high-accuracy $λ$ measurements with the ionic liquid gating technique.

description: The IPERION HS project aims at establishing and operating an integrated activity for the establishment of a distributed pan-European research infrastructure on heritage science. Since 2016 heritage science is included in the ESFRI Roadmap through E-RIHS, the European Research Infrastructure on Heritage Science, evolving towards becoming an ERIC. Looking forward towards such time, IPERION HS will provide the pan-European heritage science community with a further level of integration and its rules and procedures are aimed at adaptation and improvement for future adoption under E-RIHS ERIC. As results from the working of a previous project of organizational nature (E-RIHS PP) the quality of a partner to the future ERIC will be established through an evaluation combining: i) a confirmation of the capacity to do things well; and ii) an assurance that such capacity is suitably managed to bear fruit in terms of results. For that purpose, the outcomes of actions taken by a partner will be evaluated as pertains e.g. their impact and the satisfaction of users. Known partners, those that have already co-operated within the group and are therefore recognized by their activities and the respective results, will be subjected to a simplified evaluation, namely attending to existing feedback from previous users, while new partners will be subjected to a complete evaluation. One of the main aims of quality monitoring under IPERION HS is to establish a background of data allowing to consider the partners of this project for a simplified evaluation scheme if, in the future, they apply to become partners to E-RIHS ERIC. A basic quality and evaluation system for the services rendered through the project and for its other outcomes is set by this task, based on flexibility and self-evaluation. The task also sets a group of Key Performance Indicators (KPIs) from which should evolve those to be used after the ERIC is established. KPIs will be aimed at forming a reliable picture of the evolution of the project in terms of conformity with set goals, progression of important factors and satisfaction of users in the broad sense of the word. Finally, the task will set ethical principles by which all those working within the Project and, later, under the E-RIHS brand are bound to abide. Those principles are expected to be consequent through procedures followed in all operations. The deliverable was developed from work done under E-RIHS PP and from the results of an ESFRI Working Group on the monitoring of research infrastructures performance published in December 2019. It includes contributions of IPERION HS WP 2, WP 3 and WP 4 on the survey of users’ satisfaction and of WP 8 on the dissemination and communication KPIs.

description: Strongly interacting gauge mediation (SIGM) of supersymmetry breaking is very attractive, since it naturally predicts a light gravitino of mass $\lsim{\cal O}(10)$ eV, which causes no cosmological problem. We discuss various signatures of the SIGM in the early stage (a low integrated luminosity period) of the LHC experiments. We show, in particular, a possible way to discriminate it from the conventional gauge mediation by counting the number of high $P_{\rm T}$ leptons.

description: Cowan et al. (2021) review how roughly half the elements heavier than iron found in the Sun are produced by rapid neutron capture and half by slow neutron capture, the r- and s-processes. In the Sun, their relative contribution to individual elemental abundances is well understood, except for the lightest and heaviest elements beyond iron. Their contributions are especially uncertain for the heaviest non-radioactive element, lead (Pb, Z=82). This is constrained by deriving lead abundances in metal-poor stars. For in the most metal-poor halo stars, strontium and heavier elements are found in the solar r-process proportion; s-process elements appear only at metallicities above one-thirtieth solar. In unevolved metal-poor stars of roughly solar heavy-element content, only two UV Pb lines are detectable. Four such stars have high-resolution spectra of the strongest line, Pb II at 2203.53A. Roederer et al. (2020) analyzed this line in one star, deriving a lead-to-iron abundance ratio ten times solar. This and its blue-shifted profile suggested strong s-process production. This work analyzes the UV spectra of all four stars. Calculations including a predicted Fe I line blueward of the Pb II line, and assuming the lead abundance scales with r-process abundances, match all four profiles extremely well. A scaled s-process contribution might improve the match to the much lower lead abundance found in the unevolved star analyzed previously, but its s-process excess is modest. An Fe II line blends the other lead line, Pb I at 2833.05A, which constrains the lead abundance only in the coolest star.

description: The Yablonskii-Vorob'ev polynomials $y_{n}(t)$, which are defined by a second order bilinear differential-difference equation, provide rational solutions of the Toda lattice. They are also polynomial tau-functions for the rational solutions of the second Painlevé equation ($P_{II}$). Here we define two-variable polynomials $Y_{n}(t,h)$ on a lattice with spacing $h$, by considering rational solutions of the discrete time Toda lattice as introduced by Suris. These polynomials are shown to have many properties that are analogous to those of the Yablonskii-Vorob'ev polynomials, to which they reduce when $h=0$. They also provide rational solutions for a particular discretisation of $P_{II}$, namely the so called {\it alternate discrete} $P_{II}$, and this connection leads to an expression in terms of the Umemura polynomials for the third Painlevé equation ($P_{III}$). It is shown that Bäcklund transformation for the alternate discrete Painlevé equation is a symplectic map, and the shift in time is also symplectic. Finally we present a Lax pair for the alternate discrete $P_{II}$, which recovers Jimbo and Miwa's Lax pair for $P_{II}$ in the continuum limit $h\to 0$.

We study the distribution of elastic energy stored in such systems from experiments, and high-resolution digital techniques. It is found that the set where the elastic energy of curvature is concentrated has dimension $D_\mathcal{S} = 1.0 \pm 0.1$, while the set where the mass is distributed, has dimension $D =1.9 \pm 0.1$.

PDM: Predator Data Mining
Un nuovo approccio al Data Mining Unsupervised
Creators: name: Del Mondo, Carmine
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: Si presenta in questa tesi un nuovo algoritmo adatto alla soluzione di un ampia categoria
di problemi di data mining unsupervised: il PDM (Predator Data Mining).
Il PDM determina dei buoni centri di aggregazione dell’insieme dei dati classificandoli
rispetto ad essi. I centri di aggregazione possono essere i classici centroidi, o strutture
pi`u o meno complesse. Queste possono immagazzinare, e quindi permettere di estrarre,
maggiori, o comunque diverse informazioni rispetto alla classica operazione di data
clustering, che `e comunque un caso particolare del PDM
L’algoritmo sfrutta un approccio originale al problema che consiste nell’estrarre informazioni
dall’insieme di dati, che vengono considerate come risorse per un insieme
parallelo di “predatori”. Gli insiemi di predatori sono generati da un particolare algoritmo
evolutivo chiamato Competitive Evoluntion on Data (CED). L’insieme dei dati viene
visto dal CED come un insieme di risorse: un ambiente, all’interno del quale popolazioni
di predatori competono. Il PDM, tramite tecniche di data clustering, estrae, da alcune
delle popolazioni generate dalla dinamica evolutiva del CED, i predatori che ritiene pi`u
significativi, la metrica utilizzata tra i predatori è definita intrinsicamente nell’algoritmo
ed è indipendente dal particolare predatore adottato.
In questa tesi si è rivolta l’attenzione ad un particolare tipo di dati (punti in Rn, si
sono fatti vedere alcuni esempi di utilizzo con classe di predatori differente, usandolo
come classico algoritmo di Data Clustering lo si è confrontato su alcuni data set che simulano
l’espressione genetica dei geni (microarray) con gli algoritmi più frequentemente
usati in quest’ambito, ed infine si `e applicato il PDM su un data base reale confrontando i
risultati con quelli ottenuti e pubblicati sullo stesso con altri procedimenti.
Inoltre, nell’acquisizione degli strumenti necessari per l’elaborazione dell’algoritmo,
si sono fatte alcune considerazioni significative sui coefficienti utilizzati per confrontare
classificazioni. In pratica si associa ad un risultato di un operazione di clustering un classificatore
booleano, chiamato di accoppiamento, che unifica i coefficienti utilizzati nel
confronto tra classificazioni unsupervised con quelli utilizzati tra classificazioni supervised.
Questa unificazione permette tra l’altro di definire nuovi coefficienti che hanno
interessanti caratteristiche.

description: La fissazione rigida con placche e viti in titanio nella traumatologia maxillo-facciale ha consentito di ottenere notevoli miglioramenti nel consolidamento dei capi ossei, riducendo i tempi di contenzione e conferendo una maggiore stabilità degli stessi. Recentemente, abbiamo assistito ad una vera e propria evoluzione dei materiali di osteosintesi che ha portato all’utilizzo di materiale riassorbibile ovvero biodegradabile in chirurgia maxillo-facciale. Le prime ricerche sull’impiego di materiale bioassorbibile in chirurgia maxillo-facciale furono effettuate all’inizio degli anni ’70 ad opera di Cutright ed il materiale utilizzato erano omopolimeri, molecole costituite da acido poli L-lattico (PLLA), acido poliglicolico (PGA), polidiossannone (PDS). Oggi sono introdotti sul mercato copolimeri che garantiscono una buona stabilità per 6-8 settimane ed hanno un tempo di riassorbimento compreso tra 9 e 15 mesi.
I copolimeri presi in esame sono sempre il PLLA e il PGA assemblati in varie percentuali in base all’industria produttrice. Questi polimeri bioassorbibili sono costituiti da macromolecole che, messi in un sistema biologico, vengono coinvolti in una reazione chimica che porta alla formazione di frammenti a più basso peso molecolare, attraverso una rottura progressiva dei legami della catena principale per polimeri lineari ed, eventualmente, attraverso la frammentazione dei punti di reticolazione. Gli obiettivi di questo studio sono stati la valutazione a medio e lungo termine sulla stabilità dei mezzi di fissazione bio-assorbibili che vengono utilizzati nella fissazione dei segmenti ossei osteotomizzati nel trattamento dei pazienti affetti da malformazioni dento-scheletriche.

description: As is well known, gravitational wave detections of coalescing binaries are standard sirens, allowing a measurement of source distance by gravitational wave means alone. In this paper we explore the analogue of this capability for continuous gravitational wave emission from individual spinning neutron stars, whose spin-down is driven purely by gravitational wave emission. We show that in this case, the distance measurement is always degenerate with one other parameter, which can be taken to be the moment of inertia of the star. We quantify the accuracy to which such degenerate measurements can be made. We also discuss the practical application of this method to scenarios where one or other of distance or moment of inertia is constrained, breaking this degeneracy and allowing a measurement of the remaining parameter. We consider a broad range of possible, unknown parameters, as well as we present results for the aLIGO and Einstein Telescope sensitivities. Our results will be of use following the eventual detection of a neutron star spinning down through such gravitational wave emission.

description: L'obiettivo principale della Tesi di Dottorato è stato quello di definire metodologie numeriche per il disegno e l’analisi di un sistema di alleviazione del carico di manovra che tenga conto dell’elasticità della struttura, nonché di quantificare i benefici derivanti dall’utilizzo di tali sistemi in termini di allungamento della vita a fatica.
Le metodologie sviluppate sono di tipo teorico/numerico.
Nel corso del primo anno è stata messa a punto una metodologia per il calcolo dei parametri di equilibrio del velivolo elastico in manovra quasi-statica bilanciata ed un metodo per ridurre il carico strutturale alare. Nel corso del secondo anno è stata messa a punto una metodologia per il calcolo dell’efficacia aeroelastica di una superficie mobile quando essa è utilizzata per alleviare il carico da manovra simmetrica non stazionaria. L’attività del terzo anno è consistita nel disegno concettuale di un sistema automatico di controllo dei carichi da manovra in volo longitudinale. E’ stata definita l’architettura del sistema aero-servo-elastico a loop chiuso per il controllo simultaneo del fattore di carico e del momento flettente nella stazione dell’ala più sollecitata. Sono state eseguite applicazioni numeriche su velivolo a configurazione non convenzionale e a configurazione classica (joined-wing UAV e CS-25 business jet). Infine, è stato stimato il miglioramento della vita a fatica derivante dall’utilizzo di un sistema automatico di controllo dei carichi, per elementi strutturali alari dimensionati a momento flettente.
I risultati numerici ottenuti in termini di riduzione del carico di manovra sono rilevanti. Sono state registrate diminuzioni del momento flettente alla radice alare fino ad oltre il 30%, sia in caso di velivoli a configurazione fortemente non convenzionale (joined-wing), sia in caso di velivoli classici. La principale limitazione della metodologia consiste nel fatto che il carico è osservato e controllato in un’unica stazione alare, generalmente la più caricata che, in caso di architetture fortemente non convenzionali, potrebbe non coincidere con la radice alare. Tuttavia è possibile generalizzare il metodo introducendo altre superfici mobili dedicate all’alleviazione del carico per il controllo simultaneo in più stazioni. Appare difficile che sistemi di “load control” possano portare alla riduzione del peso strutturale data la reticenza degli Enti Certificanti ad accettare che la progettazione strutturale sia eseguita “a carico ridotto” senza prevedere eccessive ridondanze dei sistemi. D’altro canto l’allungamento della vita a fatica costituisce un beneficio di fortissimo interesse industriale. Sono stati stimati allungamenti della vita a fatica fino ad oltre il 50%, per elementi strutturali dimensionati a momento flettente.

description: The Coulomb gauge in QCD is the only explicitly unitary gauge. But it suffers from energy-divergences which means that it is not rigorously well-defined. One way to define it unambiguously is as the limit of a gauge interpolating between the Landau gauge and the Coulomb gauge. This interpolating gauge is characterised by a parameter theta and the Coulomb gauge is obtained in the limit theta tends to zero. We study the renormalization of this theta-gauge for all values of theta, and note some special features of it.

Anti-biofilm activity of a polysaccharide from marine sponge
associated Bacillus licheniformis

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: Secondary metabolites ranging from furanone to exo-polysaccharides have been suggested to have anti-biofilm activity in various recent studies. Among these,Escherichia coli group II capsular polysaccharides were shown to inhibit biofilm formation in a wide range of organisms and more recently marine Vibrio sp. and Kingella kingae were found to secrete complex exopolysaccharides having the potential for broad-spectrum biofilm inhibition and disruption.
In this study, a ca. 1800 kDA polysaccharide having simple monomeric units of α-Dgalactopyranosyl-(1→2)-glycerol-phosphate was found to exert an anti-biofilm activity
against both Gram-positive and Gram-negative bacteria without any bactericidal effect.
This polysaccharide was extracted from a Bacillus licheniformis strain associated with the Mediterranean marine organism Spongia officinalis. Unlike most of the anti-biofilm compounds, the mechanism of action of the compound was most likely independent from quorum sensing, as its structure is unrelated to any of the so far known quorum sensing molecules. This was unexpected, since previous studies had shown that the combined action of α-D-galactopyranosyl-glycerol (floridoside) and isethionic acid (floridosideisethionic acid complex) from red algae had anti-biofilm effect through quorum sensing inhibition.
Other experiments revealed that treatment of abiotic surfaces with the present polysaccharide blocked and/or reduced the initial adhesion and biofilm development of
strains such as Escherichia coli PHL628 and Pseudomonas fluorescens. In addition the polysaccharide reduced the cell surface hydrophobicity of the tested strains which
appeared to be a cause of reduction of cell-cell or cell-surface interaction during the initial attachment stage of biofilm development.
Further research on such surface-active compounds might help in developing novel and more potential anti-biofilm molecules.

description: Exact solutions of Einstein equations with null Riemman-Christoffel curvature tensor everywhere, except on a hypersurface, are studied using quantum particles obeying the Klein-Gordon equation. We consider the particular cases when the curvature is represented by a Dirac delta function with support either on a sphere or on a cylinder (spherical and cylindrical shells). In particular, we analyze the necessity of extra boundary conditions on the shells.

Toroidal Magnetic Fields in Type II Superconducting Neutron Stars
Creators: name: Akgun, Taner

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We determine constraints on the form of axisymmetric toroidal magnetic fields dictated by hydrostatic balance in a type II superconducting neutron star with a barotropic equation of state. Using Lagrangian perturbation theory, we find the quadrupolar distortions due to such fields for various models of neutron stars with type II superconducting and normal regions. We find that the star becomes prolate and can be sufficiently distorted to display precession with a period of the order of years. We also study the stability of such fields using an energy principle, which allows us to extend the stability criteria established by R. J. Tayler for normal conductors to more general media with magnetic free energy that depends on density and magnetic induction, such as type II superconductors. We also derive the growth rate and instability conditions for a specific instability of type II superconductors, first discussed by P. Muzikar, C. J. Pethick and P. H. Roberts, using a local analysis based on perturbations around a uniform background.

Higgs hunting with B decays

description: B physics is sensitive to the effects of Higgs bosons in the Minimal Supersymmetric Standard Model, if the parameter tan beta is large. I briefly summarise the role of B -> mu+ mu- and B -> tau nu in the hunt for new Higgs effects and present new results on the decay B -> D tau nu: Using the analyticity properties of form factors one can predict the ratio R=Br(B -> D tau nu)/Br(B -> D l nu), l=e,mu, with small hadronic uncertainties. In the Standard Model one finds R= 0.31 +/- 0.02, Br(B^- -> D^0 tau^- anti-nu) = (0.71 +/- 0.09)% and Br(anti-B^0 -> D^+ tau^- anti-nu)= (0.66 +/- 0.08)%, if the vector form factor of the Heavy Flavor Averaging Group is used. B -> D tau nu is competitive with B -> tau nu in the search for effects of charged Higgs bosons. Especially sensitive to the latter is the differential distribution in the decay chain anti-B -> D anti-nu tau^-[->pi- nu].

Fluctuation scaling in complex systems: Taylor's law and beyond

description: Complex systems consist of many interacting elements which participate in some dynamical process. The activity of various elements is often different and the fluctuation in the activity of an element grows monotonically with the average activity. This relationship is often of the form "$fluctuations \approx const.\times average^α$", where the exponent $α$ is predominantly in the range $[1/2, 1]$. This power law has been observed in a very wide range of disciplines, ranging from population dynamics through the Internet to the stock market and it is often treated under the names \emph{Taylor's law} or \emph{fluctuation scaling}. This review attempts to show how general the above scaling relationship is by surveying the literature, as well as by reporting some new empirical data and model calculations. We also show some basic principles that can underlie the generality of the phenomenon. This is followed by a mean-field framework based on sums of random variables. In this context the emergence of fluctuation scaling is equivalent to some corresponding limit theorems. In certain physical systems fluctuation scaling can be related to finite size scaling.

The Challenge of Variable Effort Crowdsourcing and How Visible Gold Can Help

description: We consider a class of variable effort human annotation tasks in which the number of labels required per item can greatly vary (e.g., finding all faces in an image, named entities in a text, bird calls in an audio recording, etc.). In such tasks, some items require far more effort than others to annotate. Furthermore, the per-item annotation effort is not known until after each item is annotated since determining the number of labels required is an implicit part of the annotation task itself. On an image bounding-box task with crowdsourced annotators, we show that annotator accuracy and recall consistently drop as effort increases. We hypothesize reasons for this drop and investigate a set of approaches to counteract it. Firstly, we benchmark on this task a set of general best-practice methods for quality crowdsourcing. Notably, only one of these methods actually improves quality: the use of visible gold questions that provide periodic feedback to workers on their accuracy as they work. Given these promising results, we then investigate and evaluate variants of the visible gold approach, yielding further improvement. Final results show a 7% improvement in bounding-box accuracy over the baseline. We discuss the generality of the visible gold approach and promising directions for future research.

description: La tesi "Virgilio tra ideologia e potere" ha per argomento il rapporto complesso che legò il poeta di Mantova a colui che, nel medesimo periodo storico, dominò la scena politica romana, ossia Ottaviano. Bucoliche, Georgiche ed Eneide sono analizzate al fine di dimostrare l'evoluzione, avvenuta nel corso di molti anni, dell'amicizia che legò il poeta al politico, allo scopo di riscattare Virgilio dalle accuse di servilismo mossegli dai critici nel corso dei secoli.

description: Using pulsed laser ablation with arsenic over pressure, the growth conditions for GaAs nanowires have been systematically investigated and optimized. Arsenic over pressure with As$_2$ molecules was introduced to the system by thermal decomposition of polycrystalline GaAs to control the stoichiometry and shape of the nanowires during growth. GaAs nanowires exhibit a variety of geometries under varying arsenic over pressure, which can be understood by different growth processes via vapor-liquid-solid mechanism. Single-crystal GaAs nanowires with uniform diameter, lengths over 20 $μ$m, and thin surface oxide layer were obtained and can potentially be used for further electronic characterization.

description: The research activity, performed at the institute for Microelectronic and Microsystems, has been devoted to the study and the development of non-destructive optical techniques for morphological analysis of biological samples. A digital holographic microscope has been designed and set up, compatible with micro-manufactured devices, for a label-free, non-destructive characterization of biological samples, as particular regard to bovine and human spermatozoa. Moreover, dedicated algorithms have been developed in order to elaborate the acquired hologram and to retrieve the needed biological parameters of the analyzed sample.

description: We present a novel approach to spin manipulation in atomic-scale nanostructures. Our ab initio calculations clearly demonstrate that it is possible to tune magnetic properties of sub-nanometer structures by adjusting the geometry of the system. By the example of two surface-based systems we demonstrate that (i) the magnetic moment of a single adatom coupled to a buried magnetic Co layer can be stabilized in either a ferromagnetic or an antiferromagnetic configuration depending on the spacer thickness. It is found that a buried Co layer has a profound effect on the exchange interaction between two magnetic impurities on the surface. (ii) The exchange interaction between magnetic adatoms can be manipulated by introducing artificial nonmagnetic Cu chains to link them.

description: Though models with the radiative neutrino mass generation are phenomenologically attractive, the complicated relationship between the flavour structure of additional Yukawa matrices and the neutrino mass matrix sometimes is a barrier to explore the models. We introduce a simple prescription to analyze the relation in a class of models with the asymmetric Yukawa structure. We then apply the treatment to the Zee-Babu model as a concrete example of the class and discuss the phenomenological consequences of the model. The combined studies among the neutrino physics, the lepton flavour violation, and the search for the new particles at the collider experiments provide the anatomy of the Zee-Babu model.
