Year: 2024

description: The following workshop description is part of an ongoing study in a thesis dissertation from the University of Extremadura in Spain, on “Social Emotional Learning and the curriculum”. The primary aim of this study is to equip teachers with the necessary knowledge, practical strategies, and resources to integrate Social and Emotional Learning (SEL) principles seamlessly into Content and Language Integrated Learning (CLIL) instruction. This integration will nurture emotionally intelligent, socially adept students, foster enriched learning experiences and prepare students for the challenges of the 21st century. During the workshop, an online survey assessed participants' initial comprehension of the concepts, aligning them with existing literature to identify knowledge gaps. Next, teacher training strategies were explored, encouraging participants to share experiences and discuss methods for improving CLIL instruction using SEL principles. Through role-playing and lesson demonstrations, attendees could actively understand and learn to apply effective SEL strategies within the CLIL context and explore diverse resources for CLIL instruction, including online materials from SEL-focused organizations and adaptable resources for diverse learners. Challenges such as teacher resistance, resource limitations, and student motivation were addressed through guided discussions. Evaluation and assessment methods, including journaling, peer observation, and professional learning communities, were presented to gauge SEL's integration into CLIL instruction. Through active engagement, small group discussions, and reflection exercises, participants collaborated throughout the workshop and by its conclusion, participants possessed a comprehensive understanding of integrating SEL into CLIL instruction, along with practical strategies and resources to enhance their teaching practices.

description: Numerical models have shown that disc dispersal via internal photoevaporation driven by the host star can successfully reproduce the observed pile-up of warm Jupiters near 1-2 au. However, since a range of different mechanisms have been proposed to cause the same feature, clear observational diagnostics of disc dispersal leaving an imprint in the observed distribution of giant planets could help to constrain the dominant mechanisms. We aim to assess the impact of disc dispersal via X-ray driven-photoevaporation (XPE) onto giant planet separations in order to provide theoretical constraints on the location and size of any possible features related to this process within their observed orbital distribution. For this purpose, we perform a set of 1D population syntheses with varying initial conditions and correlate the gas giants' final parking locations with the X-ray luminosities of their host stars in order to quantify observables of this process within the $L_\mathrm{x}$-$a$-plane of these systems. We find that XPE indeed creates an underdensity of gas giants near the gravitational radius, with corresponding pile-ups inside and/or outside of this location. However, the size and location of these features are strongly dependent on the choice of initial conditions in our model, such as the assumed formation location of the planets. XPE can strongly affect the migration process of giant planets and leave potentially observable signatures within the observed orbital separations of giant planets. However, due to the simplistic approach employed in our model, which lacks a self-consistent treatment of planet formation within an evolving disc, a quantitative analysis of the final planet population orbits is not possible. Our results however strongly motivate future studies to include realistic disc dispersal mechanisms into global planet population synthesis models.

Far-infrared reflectivity measurements including thin films of ice and a mosaic of TTF-TCNQ crystals
Creators: name: Kornelsen, Kevin E.
Publisher: name: University of British Columbia
Year: 2010

description: The main objective of this thesis project involved the design and construction of a reflectance module to be used with a far infrared Fourier spectrometer. This module would be used for specular reflectivity measurements with small samples at temperatures between liquid helium and room temperature. Early tests of this reflectance module were used to investigate some of the interesting changes in the far infrared spectrum which result from ice condensation on the sample surface. With the condensing substrate at temperatures between 130 and 200K the condensation is in a crystalline phase and can drastically reduce the intensity of the reflected radiation. The effects are most significant in the spectral range between 150 and 300cm⁻¹. Substrate temperatures lower than 130K lead to condensation of ice in a vitreous phase which does not have such a large effect on the far infrared spectrum. Modifications were made to the reflectance module design to eliminate the unpredictable effects of ice condensation and a final set of tests were performed measuring the reflectance of a mosaic of TTF-TCNQ crystals. The resulting data shows much of the fine structure which has been observed in other measurements using bolometric techniques.

description: CONCLUSIONS
This thesis aimed to define the genetical, immunological and clinical aspects of gastrointestinal inflammatory diseases in pediatrics, with attention to Inflammatory bowel disease (CD and UC) and to Eosinophilic Esophagitis (EoE). The following results were obtained and reported:
1) The characterization of mice with gut specific expression of Interleukin-12 (IL-12) family genes and their susceptibility to experimental colitis;
2) The role of Interleukin-23 receptor (IL-23R) Gene in Pediatric-Onset IBD and Genotype- Phenotype association in a pediatric population affected by IBD;
3) In order to find non invasive and offer the best therapeutical approach to patients affected by IBD we investigated the intestinal permeability test and we found that altered intestinal permeability study is predictive of early relapse in children with steroid responsive UC.
4) Then, we tried to obtain himmunoistochemical markers of small bowel inflammation in children with ulcerative colitis. We demonstrated that the density of CD25+ mononuclear cells is increase in jejunal mucosa of IBD patients, even in absence of gross endoscopic and histopathological abnormalities.
5) We also investigated the new terapeutical approach for IBD. We evaluated the effect of probiotics (VSL#3) on Induction and manteinance of remission in Children with Ulcerative colitis.
6) Finally, we riserve the last chapter of the thesis to EoE, an emerging disease in childhood: the EoE. We describe patients affected by celiac disease that also show the histological pattern of EoE. The unexpectedly high prevalence of CD in this EoE affected population and the probability of an association between gluten-induced disease and EoE prompted us to report these patients.

description: We investigate the possibility to measure the top quark mass using the collider variable $m_{T2}$ at the LHC experiment. Monte Carlo studies of $m_{T2}$ are performed with the events corresponding to the dilepton decays of $t\bar{t}$ produced at the LHC with 10 $fb^{-1}$ integrated luminosity. Our analysis suggests that the top quark mass can be determined by the $m_{T2}$ variable alone with a good precision at the level of 1 GeV.

Reduced Bloch mode expansion for periodic media band structure calculations

description: Reduced Bloch mode expansion is presented for fast periodic media band structure calculations. The expansion employs a natural basis composed of a selected reduced set of Bloch eigenfunctions. The reduced basis is selected within the irreducible Brillouin zone at high symmetry points determined by the medium's crystal structure and group theory (and possibly at additional related points). At each of the reciprocal lattice selection points, a number of Bloch eigenfunctions are selected up to the frequency range of interest for the band structure calculations. Since it is common to initially discretize the periodic unit cell and solution field using some choice of basis, reduced Bloch mode expansion is practically a secondary expansion that uses a selected set of Bloch eigenvectors. Such expansion therefore keeps, and builds on, any favorable attributes a primary expansion approach might exhibit. Being in line with the well known concept of modal analysis, the proposed approach maintains accuracy while reducing the computation time by up to two orders of magnitudes or more depending on the size and extent of the calculations. Results are presented for phononic, photonic and electronic band structures.

description: In this letter, a new notion of stability is introduced, which is called triangular stability. A system is called triangularly stable if the norm of its state vector is bounded by a decreasing linear function of time such that its intersection point with the time axis can be arbitrarily commanded by the user. Triangular stability implies prescribed-time stability, which means that the nonlinear system is converged to zero equilibrium at an arbitrary finite time. A prescribed-time controller with guaranteed triangular stability is developed for normal form nonlinear systems with uncertain input gain, which is able to reject the disturbances and unmodeled dynamics. Numerical simulations are carried out to visualize the results for second and fourth-order systems.

description: We study finite energy static solutions to a global symmetry breaking Goldstone model described by an isovector scalar field in D+1 spacetime dimensions. Both topologically stable multisolitons with arbitrary winding numbers, and zero topological charge soliton--antisoliton solutions are constructed numerically in D=3,4,5. We have explored the types of symmetries the systems should be subjected to, for there to exist multisoliton and soliton--antisoliton pairs in D=3,4,5,6. These findings are underpinned by constructing numerical solutions in the $D\le 5$ examples. Subject to axial symmetry, only multisolitons of all topological charges exist in even D, and in odd D, only zero and unit topological charge solutions exist. Subjecting the system to weaker than axial symmetries, results in the existence of all the possibilities in all dimensions. Our findings apply also to finite 'energy' solutions to Yang--Mills and Yang-Mills--Higgs systems, and in principle also sigma models.

Trust

description: Il lavoro eseguito ha per oggetto il trust, istituto, come noto, estraneo alla nostra cultura giuridica, tipico dei sistemi di common law, riconosciuto e regolato dalla Convenzione dell’ Aja, firmata il 1°luglio 1985, ratificata in Italia con L. 16 ottobre 1989, n. 364, ed entrata in vigore il 1° giugno 1992.
La ricerca svolta ha, in primo luogo, esaminato la fattispecie, con un approccio comparatistico, analizzando, nella prima parte, il contenuto e la controversa natura giuridica della citata Convenzione,  prendendo in considerazione i diversi orientamenti espressi, sul punto, dalla dottrina internazionalistica.
Successivamente, passati in rassegna gli orientamenti dottrinali e giurisprudenziali in ordine all’ammissibilità del trust interno, è stato affrontato l’interessante tema relativo al profilo strutturale dell’atto di trust, negando la configurabilità del trust c.d. auto-dichiarato.
Sulla base del principio dell’autonomia privata e della primaria regola dell’intangibilità della sfera giuridica altrui,  è stato qualificato l’atto di trasferimento dei beni in trust di natura contrattuale, in controtendenza rispetto all’orientamento prevalente che propende per una struttura unilaterale.
Nella seconda parte del lavoro, sono state esaminate alcune più importanti fattispecie del nostro ordinamento che sembrano presentare taluni caratteri analoghi  a quelli propri del trust: dal mandato senza rappresentanza, alla fiducia, al fondo patrimoniale, ai patrimoni destinati, ai fondi comuni d’investimento, alla cartolarizzazione.
Nell’ultima parte, infine, è stato affrontato, con  analisi della dottrina e giurisprudenza,  il delicato e complesso tema della compatibilità del trust con i fondamentali principi, di ordine interno, del numerus clausus dei diritti reali, della garanzia patrimoniale generica e della trascrivibilità.

description: We present an improved approach for detection of trace amounts of $^{238}$U by means of neutron activation analysis (NAA). The analysis enhancement is obtained by utilizing $γ$-$γ$ coincidence counting. An empirical method for evaluating the sensitivity gain in the presence of a large source-related background is presented. A comparison of detection limits is made between two counting schemes; namely, counting single gammas using one HPGe detector versus counting coincident gammas using two HPGe detectors placed face-to-face. A data-validated radiation transport model, created in GEANT4 for a single HPGe detector, is extended to handle the two-detector setup. In this counting scheme, a $^{238}$U-detection sensitivity enhancement of about a factor of 8 is predicted for a sample of Saint-Gobain G3 Sapphire when compared to the simpler singles counting approach.
La responsabilità professionale del notaio

description: Nel tentativo di affrontare adeguatamente il tema della responsabilità notarile, lo svolgimento della tesi ha avuto inizio con la descrizione dei tratti fondamentali della professione intellettuale in genere e del regime di responsabilità relativo ad altre categorie professionali. La qual cosa ha offerto interessanti spunti di riflessione, per aver consentito di cogliere l’evidente contrasto tra il regime adottato dalla giurisprudenza nei confronti del notaio e le soluzioni ermeneutiche preferite per altre categorie professionali. Peculiarità di disciplina giustificate, in linea di principio, dalla considerazione della complessità della figura professionale analizzata, per avere, a differenza degli altri prestatori d’opera intellettuale, i caratteri e del pubblico ufficiale e del libero professionista, ma che, invece, sembrano essere piuttosto il frutto di un perseverato atteggiamento di favore della giurisprudenza nei confronti degli esponenti della categoria professionale de qua.
Nel lavoro si è poi dato atto della vivace disputa originata dalla convergenza di ruoli accennata, innanzitutto, per i problemi ingenerati in ordine alla determinazione della natura della responsabilità imputabile al notaio per l’inadempimento dei propri doveri professionali e, quindi - assodatane la natura contrattuale nei confronti dei clienti e dei diretti destinatari dell’atto -, ai fini della individuazione dell’esatto contenuto della relativa prestazione. E, per la verità, l’indagine volta a tale ultimo scopo, già complicata per le ragioni anzidette, è stata ancor più esasperata dagli effetti della oramai acquisita classificazione dell’obbligazione professionale e, perciò, anche di quella notarile, tra le obbligazioni di “mezzi”.
L’esigenza di tentare di offrire una visione più possibile completa del ruolo del notaio, poi, ha portato ad approfondire l’esame della tanto controversa norma dell’art. 28 l. n.; disposizione da sempre oggetto di interessanti spunti di riflessione, attualmente acceso argomento di discussione per il più recente atteggiamento interpretativo assunto dalla Corte di Cassazione.
Per finire, tracciati i lineamenti della figura professionale in argomento, identificato altresì il contenuto in genere della relativa obbligazione, la trattazione ha assunto un taglio più pragmatico per riferire circa le più comuni prestazioni oggetto dell’attività notarile, unitamente alle problematiche connesse alla relativa attuazione.

description: Here we describe an autonomous way of producing more accurate prompt XRT positions for Swift-detected GRBs and their afterglows, based on UVOT astrometry and a detailed mapping between the XRT and UVOT detectors. The latter significantly reduces the dominant systematic error -- the star-tracker solution to the World Coordinate System. This technique, which is limited to times when there is significant overlap between UVOT and XRT PC-mode data, provides a factor of 2 improvement in the localisation of XRT refined positions on timescales of less than a few hours. Furthermore, the accuracy achieved is superior to astrometrically corrected XRT PC mode images at early times (for up to 24 hours), for the majority of bursts, and is comparable to the accuracy achieved by astrometrically corrected X-ray positions based on deep XRT PC-mode imaging at later times (abridged).

description: Ghost-imaging experiments correlate the outputs from two photodetectors: a high spatial-resolution (scanning pinhole or CCD camera) detector that measures a field which has not interacted with the object to be imaged, and a bucket (single-pixel) detector that collects a field that has interacted with the object. We describe a computational ghost-imaging arrangement that uses only a single-pixel detector. This configuration affords background-free imagery in the narrowband limit and a 3D sectioning capability. It clearly indicates the classical nature of ghost-image formation.

description: The transverse broadening of jets produced in deep-inelastic scattering (DIS) off a large nucleus is studied in the collinear limit. A class of medium enhanced higher twist corrections are re-summed to calculate the transverse momentum distribution of the produced collinear jet. In contrast to previous approaches, resummation of the leading length enhanced higher twist corrections is shown to lead to a two dimensional diffusion equation for the transverse momentum of the propagating jet. Results for the average transverse momentum obtained from this approach are then compared to the broadening expected from a classical Langevin analysis for the propagation of the jet under the action of the fluctuating color Lorentz force inside the nucleons. The set of approximations that lead to identical results from the two approaches are outlined. The relationship between the momentum diffusion constant $D$ and the transport coefficient $\hat{q}$ is explicitly derived.

We show that quantum tunneling of electrons between the neighboring closed orbits enveloping these pockets transforms the electron spectrum into a set of extremely narrow energy bands and gaps that decreases the total electron energy, thus leading to a \emph{magnetic breakdown induced density wave} ground state analogous to the well-known instability of Peierls type.

description: This article provides a formalism making it possible to manage the solutions of the direct and inverse kinematic models of the fully parallel manipulators. We introduce the concept of working modes to separate the solutions from the opposite geometrical model. Then, we define, for each working mode, the aspects of these manipulators. To separate the solutions from the direct kinematics model, we introduce the concept of characteristic surfaces. Then, we define the uniqueness domains, as being the greatest domains of the workspace in which there is unicity of solutions. The principal applications of this work are the design, the trajectory planning.

We compare also our proposal with the quantumness test based on quantum correlations (entanglement) and Bell inequalities. A class of quantumness witnesses associated to the phase space representation is also discussed.

description: In this study, we investigate the global ionospheric impact of high-speed solar wind streams/corotating interaction regions (HSS/CIR). A series of ten such events are identified between December 1st 2007 and April 29th 2008, characterized in the frequency domain by the main spectral peaks corresponding to 27, 13.5, 9 and 6.75 days. The spectra of solar wind magnetic field, speed and proton density, as well as those of the geomagnetic indices AE and SYM-H are solely dominated by these features. By contrast, the ionospheric NmF2 and to a lesser extent the hmF2 spectra have a much more complex structure, with secondary peaks adding to or replacing the main ones. We argue that this is evidence of the nonlinear nature of the magnetosphere-ionosphere coupling, highlighted particularly in the NmF2 ionospheric response. Additionally, we show that hmF2 is more closely correlated than NmF2 to all parameters describing the solar wind and geomagnetic activity. Finally, the ionospheric response shows higher correlation with Bz than any other solar wind parameter, and higher with SYM-H than AE, indicating that for the low-frequency part of the spectrum, high-latitude Joule heating and particle precipitation play a secondary role to that of prompt penetration electric fields in dictating the ionospheric response to geomagnetic activity, in the case of this sequence of HSS/CIR events.

The coincided discrete gamma-ray sources possess, on average, harder energetic spectra and larger intensities with respect to the rest UGS. Annihilation of dark matter concentrating in RSF is supposed to account for a possible origin of gamma-radiation.

Creators: name: Trajanovski, Naum
Publisher: name: Universität Graz
Year: 2021

description: Almost every year since 2001, on 13 January, a commemorative plaque
dedicated to Mara Buneva is mounted and, on several occasions, demolished in
the centre of Skopje. Buneva (1902-1928), who was affiliated with the rightist
interwar Internal Macedonian Revolutionary Organisation (Vnatrešna
Makedonska Revolucionerna Organizacija, VMRO), is famous for her
assassination of Velimir Prelić (1883-1928), a high-ranking representative of
the Kingdom of Serbs, Croats, and Slovenes (Kingdom SHS) on the territory of
today’s North Macedonia, as well as her immediate suicide at the crime-scene.
The present paper aims to trace the so-called mnemohistory of commemorations
of Mara Buneva in Skopje by triangulating the historical and media discourses
and political rhetoric over the commemorative events from 2001 to 2018. I argue
that the discursive shift over Mara Buneva, as well as over the commemorations
themselves, occurred after a set of groupist claims over a particular memory
site.

description: Machine learning (ML) has made incredible impacts and transformations in a wide range of vehicular applications. As the use of ML in Internet of Vehicles (IoV) continues to advance, adversarial threats and their impact have become an important subject of research worth exploring. In this paper, we focus on Sybil-based adversarial threats against a deep reinforcement learning (DRL)-assisted IoV framework and more specifically, DRL-based dynamic service placement in IoV. We carry out an experimental study with real vehicle trajectories to analyze the impact on service delay and resource congestion under different attack scenarios for the DRL-based dynamic service placement application. We further investigate the impact of the proportion of Sybil-attacked vehicles in the network. The results demonstrate that the performance is significantly affected by Sybil-based data poisoning attacks when compared to adversary-free healthy network scenario.

Bragg Reflection in Optical Waveguides

description: In this dissertation I explore the phenomenon of Bragg reflection in optical waveguides. Two specific waveguide structures are studied in detail: the Bragg fiber and a generic planar waveguide with a Bragg grating etched in it.

Bragg fibers can be classified into two groups: the air-core Bragg fiber and the coaxial Bragg fiber. Whereas the former has a plain air core at the center, the latter contains an additional high-index column in the core. Using a perturbative approach I study and compare the dispersion properties of the two types of fibers, with special attention to their potential for truly single-mode transmission. As the result a large single-mode frequency window, which also includes a zero-dispersion point, is found for the TM mode in the coaxial fiber.

The air-core Bragg fiber is also studied as a potential candidate for dispersion compensation. It is found that Bragg reflections in the fiber are capable of producing negative dispersion values at least as large as -20,000 ps/(nm•km), which is a twenty-fold improvement over previous results. The fiber parameters used for this study are somewhat unrealistic however, and further improvement is necessary before a Bragg fiber can be deployed as a Dispersion Compensating Fiber (DCF).

Optical filters based on Bragg grating structures also involve Bragg reflections. While continuous Fiber Bragg Gratings (FBG's) have long been studied and deployed as practical reflection filters, the possibility of etching a discrete grating in a (planar) waveguide has to my knowledge, never been investigated. In this dissertation I propose a novel scheme for designing such a grating, which is implemented by discretizing its continuous counterpart into a series of air holes. The relationship between the two gratings (discrete and continuous) is established in terms of the grating strength and the local grating period.

description: Invasive meningococcal disease (IMD) is a life-threatening, unpredictable condition. Vaccines are available against 5 of the 6 meningococcal serogroups (Men) accounting for nearly all IMD cases worldwide; conjugate monovalent MenC, quadrivalent MenACWY, and protein-based MenB vaccines are commonly used. We provide a comprehensive overview of the evolution of meningococcal vaccination strategies employed in national immunization programmes (NIPs) and their impact on IMD incidence in Europe. A more in-depth description is given for several countries: the United Kingdom (UK), the Netherlands, Greece, Italy, and Ireland. We searched European health authorities’ websites and PubMed. Various vaccines and immunization schedules are used in 21 NIPs. Most countries implement MenC vaccination in infants, MenACWY in adolescents, and a growing number, MenB in infants. Only Malta has introduced MenACWY vaccination in infants, and several countries reimburse immunization of toddlers. The UK, Italy, Ireland, Malta, Andorra, and San Marino recommend MenB vaccination in infants and MenACWY vaccination in adolescents, targeting the most prevalent serogroups in the most impacted age groups. Main factors determining new vaccination strategies are fluctuating IMD epidemiology, ease of vaccine implementation, ability to induce herd protection, favorable benefit–risk balance, and acceptable cost-effectiveness. Since 1999, when the UK introduced MenC vaccination, the reduction in IMD incidence has been gradually enhanced as other countries adopted routine meningococcal vaccinations. Meningococcal vaccination strategies in each country are continually adapted to regional epidemiology and national healthcare priorities. Future strategies may include broader coverage vaccines when available (e.g., MenABCWY, MenACWY), depending on prevailing epidemiology.

description: We demonstrate radiation-pressure cavity-cooling of a mechanical mode of a micromirror starting from cryogenic temperatures. To achieve that, a high-finesse Fabry-Perot cavity (F\approx 2200) was actively stabilized inside a continuous-flow 4He cryostat. We observed optical cooling of the fundamental mode of a 50mu x 50 mu x 5.4 mu singly-clamped micromirror at ω_m=3.5 MHz from 35 K to approx. 290 mK. This corresponds to a thermal occupation factor of \approx 1x10^4. The cooling performance is only limited by the mechanical quality and by the optical finesse of the system. Heating effects, e.g. due to absorption of photons in the micromirror, could not be observed. These results represent a next step towards cavity-cooling a mechanical oscillator into its quantum ground state.
title: Memory (Re)cycling: The Pilgrimage to Vukovar Remembrance Day
Creators: name: Ljubojević, Ana
Publisher: name: Universität Graz
Year: 2021

description: This paper is based on an ethnographic study carried out during the Zagreb-
Vukovar cycling marathon to the Remembrance Day commemoration. The
commemoration of the fall of Vukovar, one of the key elements of the
Croatian narrative of the Homeland War, attracts thousands of people from
all over Croatia each year. I analyse the social production of the memory of
the fall of Vukovar, a town which experienced some of the worst destruction
during the 1991-1995 war. As a result, this paper assesses the interaction
of various arenas of memory present in Vukovar, such as political and
official discourse, commemoration, popular culture and historical narrative.
Of particular interest is the relationship between individual and collective
memory, belonging and space.

description: As a model is only an abstraction of the real system, unmodeled dynamics, parameter variations, and disturbances can result in poor performance of a conventional controller based on this model. In such cases, a conventional controller cannot remain well tuned. This paper presents the control of a spherical rolling robot by using an adaptive neuro-fuzzy controller in combination with a sliding-mode control (SMC)-theory-based learning algorithm. The proposed control structure consists of a neuro-fuzzy network and a conventional controller which is used to guarantee the asymptotic stability of the system in a compact space. The parameter updating rules of the neuro-fuzzy system using SMC theory are derived, and the stability of the learning is proven using a Lyapunov function. The simulation results show that the control scheme with the proposed SMC-theory-based learning algorithm is able to not only eliminate the steady-state error but also improve the transient response performance of the spherical rolling robot without knowing its dynamic equations.
Pion transfer in gaseous hydrogen
Creators: name: Noble, Anthony James
Publisher: name: University of British Columbia
Year: 2010

description: The experiment consisted of stopping negative pions in a high pressure gas target to measure the transfer rate π-p → π-d in mixtures of H2, D2 and HD gas. The gamma rays from the decay of the π ⁰ in π -p → n + π ⁰ were detected in coincidence using two large sodium iodide crystals. The probability that a pion be transferred to a deuteron from a pionic hydrogen complex was described in terms of a phenomenological model parameterized by B and ∧. Fits to the data yielded B = 0.77 ±0.14 and ∧ = 0.21 ±0.04. These values implied that the hydrogen capture ratio in an equal mix of H2 and D2 was F(H₂D₂) = 0.45 ±0.01. The capture ratio for HD was measured to be F(HD) = 0.355 ±0.021. The ratio F(H₂D₂)/F(HD) indicated that there was likely to be internal transfer in the breakup of π-HD favouring the π-d complex at about a 60% level.

description: We study two problems, one in the field of computational finance and the other one in machine learning.

Firstly we study the Maximal drawdown statistics of the Brownian random walk. We give the infinite series representation of its distribution and consider its expected value. For the case when drift is zero, we give an exact expression of the expected value and for the other cases, we give an infinite series representation. For all the cases, we compute the limiting behavior of the expected value.

Secondly, we propose a new algorithm for boosting, AlphaBoost, which does better than AdaBoost in reducing the cost function. We study its generalization properties and compare it to AdaBoost. However, this algorithm does not always give better out-of-sample performance.

description: We devise minimalistic gauged U(1)_X Froggatt-Nielsen models which at low-energy give rise to the recently suggested discrete gauge Z_6 symmetry, proton hexality, thus stabilizing the proton. Assuming three generations of right-handed neutrinos, with the proper choice of X-charges, we obtain viable neutrino masses. Furthermore, we find scenarios such that no X-charged hidden sector superfields are needed, which from a bottom-up perspective allows the calculation of g_string, g_X and G_SM's Kac-Moody levels. The only mass scale apart from M_grav is m_soft.

description: The well known binary and decimal representations of the integers, and other similar number systems, admit many generalisations. Here, we investigate whether still every integer could have a finite expansion on a given integer base b, when we choose a digit set that does not contain 0. We prove that such digit sets exist and we provide infinitely many examples for every base b with |b|\ge 4, and for b=-2. For the special case b=-2, we give a full characterisation of all valid digit sets.
