description: Backcasting is a scenario-building technique that can help decision-makers face uncertain and complex dynamics. For this reason, backcasting is often mentioned as suitable to deal with the transition to autonomous driving. However, at present the applications of backcasting to this transition in real-world cases are quite few. The article presents a backcasting carried out in the city of Turin (Italy), aimed at defining a policy pathway to steer the transition to autonomous driving towards objectives of sustainability and liveability of the city and its neighbourhoods. It reflects on this exercise and highlights some critical issues for backcasting that emerged from its application to autonomous vehicles (AVs). The transition to AVs displays some issues that proved to challenge the effectiveness and the potentialities of implementation of backcasting. These are mainly related to: factors and levels of uncertainty, contextualization of the vision, involvement of relevant stakeholders, definition of the policy pathway. Nevertheless, the exercise showed that some solutions can be adopted to deal with these challenges, in terms of definition of background socioeconomic scenarios, combination of a range of participatory techniques, integration of collaborative and think-tank methodologies, reference to mid-term planning tools. These solutions can support further backcasting exercises for AVs.

description: One of the most distinctive features of graphene is its huge inter-Landau-level splitting in experimentally attainable magnetic fields which results in the room-temperature quantum Hall effect. In this paper we calculate the longitudinal conductivity induced by two-phonon scattering in graphene in a quantizing magnetic field at elevated temperatures. It is concluded that the purely phonon-induced scattering, negligible for conventional semiconductor heterostructures under quantum Hall conditions, becomes comparable to the disorder-induced contribution to the dissipative conductivity of graphene in the quantum Hall regime.

description: It is shown by Colding and Minicozzi the uniqueness of the tangent cone at infinity of Ricci-flat manifolds with Euclidean volume growth which has at least one tangent cone at infinity with a smooth cross section. In this article we raise an example of the Ricci-flat manifold implying that the assumption for the volume growth in the above result is essential. More precisely, we construct a complete Ricci-flat manifold of dimension 4 with non-Euclidean volume growth who has at least two distinct tangent cones at infinity and one of them has a smooth cross section.

description: Since early spring 2020, the outbreak of the COVID-19 in Italy caused schools and universities to lock and shift from traditional face-to-face classroom education to online education. In the academic field of spatial planning, online education and examples of on-line participatory process (e.g. e-planning, e-governance, etc.) are traditionally not very frequent. Through the application of an on-line participatory process to build a future vision of Bari (Apulia Region), this study explores elements related to the behavior of the knowledge agents involved in the process and compares them with the application of previous face-to-face classroom examples. The results obtained allow to collect some suggestions not only on the performance of the application in two different times, but also on the potential elements of difference to be associated to the temporal and psychological context related to the diffusion of COVID-19. Since these conditions are clearly exceptional and practically (hopefully) unrepeatable, the results seem to show a mixed perspective of effectiveness for the use of online education to build a future vision of a city.

description: Rydberg states of atomic helium with principal quantum numbers ranging from n=20 to n=100 have been prepared by non-resonance-enhanced single-color two-photon excitation from the metastable 2 {^3}S{_1} state. Photoexcitation was carried out using linearly and circularly polarized pulsed laser radiation. In the case of excitation with circularly polarized radiation, Rydberg states with azimuthal quantum number |m_{\ell}|=2 were prepared in zero electric field, and in homogeneous electric fields oriented parallel to the propagation axis of the laser radiation. In sufficiently strong electric fields, individual Rydberg-Stark states were resolved spectroscopically, highlighting the suitability of non-resonance-enhanced multiphoton excitation schemes for the preparation of long-lived high-|m_{\ell}| hydrogenic Rydberg states for deceleration and trapping experiments. Applications of similar schemes for Doppler-free excitation of positronium atoms to Rydberg states are also discussed.

description: Cities all over the world are characterized by a set of activities, which account for the concentration of people in them, achievable by means of transportation. However, this integral aspect of urban infrastructure face great challenge in most urban areas. This research examines the challenges in the existing pattern of intra-city traffic in Enugu metropolis. Six neighbourhood make up the study population drawn from three high, two medium and one low residential densities neighbourhoods based on stratified and simple random sampling technique. Data collection instrument were questionnaires administered to 400 respondents. The result of the study indicates that major travel mode within Enugu metropolis is mini buses and tricycles while commuters undergo stress during their trips regardless of the good condition of roads within the metropolis. Furthermore, it highlights traffic congestion during peak period and narrowness of most roads within the metropolis as the main challenge to existing pattern of intra-city traffic. It concludes and recommend for the re-introduction of Non-motorized transport mode of walking and cycling complemented by the Coal city public transit shuttles that once existed. It also advocates for policies that ensure decentralization of activity to reduce congestion and the need for daily travel.

description: A central challenge of developmental and evolutionary biology is to understand how anatomy is encoded in the genome. Elucidating the genetic mechanisms that control the development of specific anatomical features will require the analysis of model morphogenetic processes and an integration of biological information at genomic, cellular and tissue levels. The formation of the endoskeleton of the sea urchin embryo is a powerful experimental system for developing such an integrated view of the genomic regulatory control of morphogenesis. The dynamic cellular behaviors that underlie skeletogenesis are well understood and a complex transcriptional gene regulatory network (GRN) that underlies the specification of embryonic skeletogenic cells (primary mesenchyme cells, PMCs) has recently been elucidated. Here, we link the PMC specification GRN to genes that directly control skeletal morphogenesis. We identify new gene products that play a proximate role in skeletal morphogenesis and uncover transcriptional regulatory inputs into many of these genes. Our work extends the importance of the PMC GRN as a model developmental GRN and establishes a unique picture of the genomic regulatory control of a major morphogenetic process. Furthermore, because echinoderms exhibit diverse programs of skeletal development, the newly expanded sea urchin skeletogenic GRN will provide a foundation for comparative studies that explore the relationship between GRN evolution and morphological evolution.

description: In Berlin, measures that promote cycling and walking have moved up the political agenda and gained momentum over the last couple of years. This is in parts due to the strong involvement of civil society actors in designing, planning and implementing said measures. This article will use one of the measures planned in Berlin, as an example to illustrate the benefits and potential of cooperative planning and civic involvement in the design and implementation of drastic sustainable transport measures in cities. Cycling and walking are vital to achieving “Tomorrow’s Cities”, a vision developed by the German Environment Agency. Tomorrow’s City avoids unnecessary traffic. It is quiet, compact, green, climate-friendly and dominated by mixed-use developments. However, drastic measures changing the status quo are necessary to achieve this vision. This article argues that allowing for more civic participation and involvement and promoting experiments for sustainable mobility in public space help gain support for sustainable mobility in general, as well as the measures needed to achieve this goal. Flaniermeile Friedrichstraße, a mobility lab planned for 2020 at the heart of Berlin, serves as an interesting case of long- term civic involvement, cooperative public experiments translating an idea of sustainable mobility into temporary practice.

description: When not transporting cargo, kinesin-1 is autoinhibited by binding of a tail region to the motor domains, but the mechanism of inhibition is unclear. We report the crystal structure of a motor domain dimer in complex with its tail domain at 2.2 angstroms and compare it with a structure of the motor domain alone at 2.7 angstroms. These structures indicate that neither an induced conformational change nor steric blocking is the cause of inhibition. Instead, the tail cross-links the motor domains at a second position, in addition to the coiled coil. This "double lockdown," by cross-linking at two positions, prevents the movement of the motor domains that is needed to undock the neck linker and release adenosine diphosphate. This autoinhibition mechanism could extend to some other kinesins.

description: The literature review presented in this paper represents a part of a wider research focused on the elderly quality of life within urban environments and aimed at designing innovative tools for both public administrations and elderly citizens. The article presents a systematic review of the relevant literature regarding the development of the accessibility concept during the 1959-2020 period. Nearly 6,000 documents were selected from the Scopus database, using the keywords “urban accessibility” and limiting the results to the fields of Urban Studies and Social Sciences to select the documents for the bibliometric analyses run. They were run in R Studio environment through a tool, developed in 2017, named bibliometrix. These analyses were run to highlight the main traits of the urban accessibility concept and developed methodologies and measures, in order to implement it in real-world practices and tools. The extensive and systematic literature review shows that for many years much of this scientific production has a deep theoretical nature, rather than practical. That was mostly due to difficulties in computing and introducing accessibility measures in decision-making practices. The advent of GIS has made much more practical the development of accessibility-oriented planning tools, and many commercial packages are now available.

description: Abstract

Purpose: While water activities are often part of the Integrated Special Education Program (PPKI), there is currently no published guide for special integration education teachers (GPKI) to effectively support students with learning disabilities during these activities. The Aqua Explorers module was developed to fill this gap, and this study aims to assess the validity and reliability of the instruments designed to evaluate the module’s effectiveness. Methodology: The validity of the questionnaire and interview instruments was determined through evaluations by four experts, utilizing Cohen’s Kappa coefficient to gauge validity. The reliability of the questionnaire was assessed using Cronbach’s Alpha correlation coefficient, while interview instruments were refined based on expert feedback. Findings: The Cohen’s Kappa test yielded values of 0.460 and 0.658, indicating moderate agreement, while the Cronbach’s Alpha for the questionnaire was 0.86, reflecting high reliability. For the interview instruments, revisions were made following a pilot test and supervisor review, enhancing their reliability. Overall, the results indicate that the validity and reliability of the instruments are at a satisfactory level, making them suitable for use.

description: The Lunar Lander Neutron and Dosimetry (LND) Experiment aboard the Chang$'$E-4 Lander on the lunar-far side measures energetic charged and neutral particles and monitors the corresponding radiation levels. During solar quiet times, galactic cosmic rays (GCRs) are the dominating component of charged particles on the lunar surface. Moreover, the interaction of GCRs with the lunar regolith also results in upward directed albedo protons which are measured by the LND. In this work, we used calibrated LND data to study the GCR primary and albedo protons. We calculate the averaged GCR proton spectrum in the range of 9 368 MeV and the averaged albedo proton flux between 64.7 and 76.7 MeV from June 2019 (the 7th lunar day after Chang$'$E-4$'$s landing) to July 2020 (the 20th lunar day). We compare the primary proton measurements of LND with the Electron Proton Helium INstrument (EPHIN) on SOHO. The comparison shows a reasonable agreement of the GCR proton spectra among different instruments and illustrates the capability of LND. Likewise, the albedo proton measurements of LND are also comparable with measurements by the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) during solar minimum. Our measurements confirm predictions from the Radiation Environment and Dose at the Moon (REDMoon) model. Finally, we provide the ratio of albedo protons to primary protons for measurements in the energy range of 64.7-76.7 MeV which confirms simulations over a broader energy range.

description: We briefly review recent progress on ultracold atomic Fermi gases with different types of synthetic spin-orbit coupling, including the one-dimensional (1D) equal weight Rashba-Dresselhaus and two-dimensional (2D) Rasbha spin-orbit couplings. Theoretically, we show how the single-body, two-body and many-body properties of Fermi gases are dramatically changed by spin-orbit coupling. In particular, the interplay between spin-orbit coupling and interatomic interaction may lead to several long-sought exotic superfluid phases at low temperatures, such as anisotropic superfluid, topological superfluid and inhomogeneous superfluid. Experimentally, only the first type - equal weight combination of Rasbha and Dresselhaus spin-orbit couplings - has been realized very recently using a two-photon Raman process. We show how to characterize a normal spin-orbit coupled atomic Fermi gas in both non-interacting and strongly-interacting limits, using particularly momentum-resolved radio-frequency spectroscopy. The experimental demonstration of a strongly-interacting spin-orbit coupled Fermi gas opens a promising way to observe various exotic superfluid phases in the near future.

description: Specific (13)C labeling of Thr methyl groups has been accomplished via the growth of a standard laboratory strain of Escherichia coli on [2-(13)C]glycerol in the presence of deuterated isoketovalerate, Ile, and Ala. Diversion of the label from the Thr biosynthetic pathway is suppressed by including Lys, Met, and Ile in the growth medium. This method complements the repertoire of methyl labeling schemes for NMR structural and dynamic studies of proteins and is particularly useful for the study of nucleic acid binding proteins because of the high propensity of Thr residues at protein-DNA and -RNA interfaces.

description: The number and role of whole-genome duplications in vertebrate evolution has intrigued evolutionary biologists since Ohno first proposed genome duplication as the force driving the 'big leap' in vertebrate morphological innovation. Attempts to resolve these issues have been thwarted by small and noisy datasets, and by lack of computational accuracy and statistical rigor. Recently, Ken Wolfe and colleagues presented a genome-scale, statistically rigorous analysis of evidence based on the spatial organization of duplicated genes, as well as estimates of duplication times. Their results provide the strongest evidence to date of large-scale duplication throughout the vertebrate genome, consistent with at least one whole-genome duplication.

description: Traffic-induced vibrations are a frequent problem with buildings. When a heavy vehicle such as a bus or a truck strikes an irregularity in a road surface, an impact load is generated which, in turn, gives rise to vibrations that travel through the soil. Soil - particularly its type and stratification - is but one factor influencing the transmission of vibrations. They are usually worst in areas underlain by a thick but soft clay soil layer. Vibrations rarely cause direct damage and are actually more of an annoyance for homeowners than anything else. For activities that require a vibration-free work area, structures can be built that absorb traffic-induced vibrations.
description: Les vibrations dues à la circulation constituent souvent un problème, dans les bâtiments. Lorsqu'un véhicule lourd, par exemple un autobus ou un camion, passe sur une irrégularité de la chaussée, il produit une charge d'impact qui provoque des vibrations se propageant dans le sol. Le type et la stratification du sol constituent un des facteurs qui influent sur la transmission des vibrations. Celles-ci sont habituellement plus fortes dans les zones comportant une épaisse couche d'argile plastique. Il est rare que les vibrations soient directement à l'origine des dommages; elles constituent plutôt un désagrément pour les propriétaires de maisons. Dans le cas d'activités qui exigent une aire de travail exempte de vibrations, on peut construire des ouvrages qui absorbent les vibrations dues à la circulation.

description: The Landau--Zener (LZ) type classical-trajectory surface-hopping algorithm is applied to the nonadiabatic nuclear dynamics of the ammonia cation after photoionization of the ground-state neutral molecule to the excited states of the cation. The algorithm employs the recently proposed formula for nonadiabatic LZ transition probabilities derived from the adiabatic potential energy surfaces. The evolution of the populations of the ground state and the two lowest excited adiabatic states is calculated up to 200 fs. The results agree well with quantum simulations available for the first 100 fs based on the same potential energy surfaces. Four different time scales are detected for the nuclear dynamics: Ultrafast Jahn--Teller dynamics between the excited states on a 5 fs time scale; fast transitions between the excited state and the ground state within a time scale of 20 fs; relatively slow partial conversion of a first-excited-state population to the ground state within a time scale of 100 fs; and nearly constant populations after roughly 120 fs due to a dynamical equilibrium between all three states. The latter provides a possible explanation of the experimental evidence that ammonia cation is nonfluorescent.
About the Sustainability of Urban Settlements

description: Urbanization is an onerous human activity: it affects municipal budget and foremost it costs the environment. Nevertheless, an ever-growing number of people (more than 75% of the European population) is living in cities and towns, so that identifying sustainable urban development solutions is a dramatically urgent need. Already in the 70s, some researches proposed parameters to evaluate urbanization costs in Italy, but they mainly focused on the economic and financial sustainability of real estate development. The land value capturing approaches proved to be inadequate when municipal budgets are facing growing social unbalances and critical environmental threats. The question being not just “where the money for urban infrastructures could come from”, but also “what could be a more sustainable development model”. In any case, now we are forced to rethink the whole organization of our urban life to defend ourselves from largely unknown threats, pandemics, COVID-19 being probably one among others that we could face in the near future. It is not yet clear if a link exists between the spread of the virus, the health consequences and the environmental conditions, but what probably will need to be assessed is the effect of population density on the spread of contamination. Even the traditional provision of services and public spaces will need to be defined again in order to protect and serve urban population. New evidences will force planners to redefine their thoughts and schemes.

description: Biofilms of Candida albicans include both yeast cells and hyphae. Prior studies indicated that a zap1Δ/Δ mutant, defective in zinc regulator Zap1, has increased accumulation of yeast cells in biofilms. This altered yeast-hypha balance may arise from internal regulatory alterations or from an effect on the production of diffusible quorum-sensing (QS) molecules. Here, we develop biosensor reporter strains that express yeast-specific YWP1-RFP or hypha-specific HWP1-RFP, along with a constitutive TDH3-GFP normalization standard. Seeding these biosensor strains into biofilms allows a biological activity assay of the surrounding biofilm milieu. A zap1Δ/Δ biofilm induces the yeast-specific YWP1-RFP reporter in a wild-type biosensor strain, as determined by both quantitative reverse transcription-PCR (qRT-PCR) gene expression measurements and confocal microscopy. Remediation of the zap1Δ/Δ zinc uptake defect through zinc transporter gene ZRT2 overexpression reverses induction of the yeast-specific YWP1-RFP reporter. Gas chromatography-mass spectrometry (GC-MS) measurements of known organic QS molecules show that the zap1Δ/Δ mutant accumulates significantly less farnesol than wild-type or complemented strains and that ZRT2 overexpression does not affect farnesol accumulation. Farnesol is a well-characterized inhibitor of hypha formation; hence, a reduction in farnesol levels in zap1Δ/Δ biofilms is unexpected. Our findings argue that a Zap1- and zinc-dependent signal affects the yeast-hypha balance and that it is operative in the low-farnesol environment of the zap1Δ/Δ biofilm. In addition, our results indicate that Zap1 is a positive regulator of farnesol accumulation.

description: In hot-applied bituminous roof membranes, voids built into the roof during installation become blisters. These voids can result from skips in bitumen mopping, entrapped moisture, uneven substrates, and several other causes. Entrapped moisture, for example, expands and contracts, growing into an ever larger blister. The best safeguard against blistering often lies in good membrane installation: this includes maintaining the requisite temperature for the mopping asphalt, applying it uniformly and thinly, flattening the membrane before rolling it out, and heeding several other forethoughts.

Par exemple, la vapeur d'eau présente dans un vide peut se contracter ou se dilater, augmentant dans ce dernier cas le volume de la boursouflure. Une bonne façon d'empêcher la formation de boursouflures est de bien poser la membrane en choisissant la température appropriée dans le cas du bitume de collage, en étendant bien la membrane, et en appliquant le bitume de collage de manière uniforme et en couche mince.

description: We consider stochastic partial differential equations under minimal assumptions: the coefficients are merely bounded and measurable and satisfy the stochastic parabolicity condition. In particular, the diffusion term is allowed to be scaling-critical. We derive local supremum estimates with a stochastic adaptation of De Giorgi's iteration and establish a weak Harnack inequality for the solutions. The latter is then used to obtain pointwise almost sure continuity.

description: Neutron stars are the densest objects in the Universe. In this paper we consider so-called inner crust - the layer, where neutron-excess nuclei are immersed into degenerate gas of electrons and sea of quasi-free neutrons. It was generally believed that spherical nuclei become unstable with respect to quadrupole deformations at high densities and here we consider this instability. Within perturbative approach we show that spherical nuclei with equilibrium number density are, in fact, stable with respect to infinitesimal quadrupole deformation. This is due to background of degenerate electrons and associated electrostatic potential which maintain stability of spherical nuclei. However, if the number of atomic nuclei per unit volume is much less than the equilibrium value, instability can arise. To avoid confusion we stress that our results are limited to infinitesimal deformations and do not guaranty strict thermodynamic stability of spherical nuclei. In particular, they does not exclude that substantially non-spherical nuclei (so-called pasta phase) represent thermodynamic equilibrium state of the densest layers of neutron star crust. Rather our results points that spherical nuclei can be metastable even if they are not energetically favourable and the timescale of transformation of spherical nuclei to the pasta phases should be estimated subsequently.

Fast Fusion of Multi-Band Images Based on Solving a Sylvester Equation

description: This paper proposes a fast multi-band image fusion algorithm, which combines a high-spatial low-spectral resolution image and a low-spatial high-spectral resolution image. The well admitted forward model is explored to form the likelihoods of the observations. Maximizing the likelihoods leads to solving a Sylvester equation. By exploiting the properties of the circulant and downsampling matrices associated with the fusion problem, a closed-form solution for the corresponding Sylvester equation is obtained explicitly, getting rid of any iterative update step. Coupled with the alternating direction method of multipliers and the block coordinate descent method, the proposed algorithm can be easily generalized to incorporate prior information for the fusion problem, allowing a Bayesian estimator. Simulation results show that the proposed algorithm achieves the same performance as existing algorithms with the advantage of significantly decreasing the computational complexity of these algorithms.
Virucity. Rethinking the urban system

description: The paper focuses attention on three fundamental points. The first one concerns an analysis of the urban condition perceived and detected directly by the observation of the city suddenly deprived of the fruition component and characterized by the functional reset of urban activities with the exception of health functions. The second element is attributable to a systemic interpretation of the phenomenon through the analysis of the effects on urban subsystems produced by the pandemic, recalling the holistic approach to the study of urban phenomena. The third element concerns the envisaging of possible post-virus urban scenarios for which a significant bifurcation is foreseen: on the one hand, if the virus produced a rethinking of life models and the need for new ways of acting and interacting in the city we could imagine an urban future characterized by a general rebalancing of anthropic contexts; on the other hand, if the desire to return to entropic and energy-consuming models will prevail, we will continue to witness the slow degradation of human and natural habitats that will lead to the “right” extinction of human beings. These alternatives underlie a series of dilemmas that the paper emphasizes as structuring elements of possible future urban scenarios, highlighting the fundamental role of urban scientists and planners.

description: The supply air in an open-plan office, whose floor space is usually subdivided into a warren of small, partitioned work areas, is normally distributed through diffusers. The quest is one of providing adequate ventilation for every work area. Based on IRC research, most, if not all, assumptions about the possible role that the layout of diffusers may play in air distribution can be safely dismissed. Only one condition concerning diffuser layouts must be observed for the sake of expedient removal of air contaminants.
description: Dans les bureaux en espace fonctionnel, où l'on trouve habituellement toute une série de postes de travail séparés par des cloisons à hauteur d'homme, l'air soufflé est normalement distribué par les diffuseurs. Encore faut-il assurer une ventilation adéquate à tous les travailleurs. D'après les recherches réalisées par l'IRC, on ne doit pas hésiter à réfuter la plupart, sinon la totalité des hypothèses touchant l'influence que peut avoir, sur le plan de la distribution de l'air, la disposition des diffuseurs. Il n'y a qu'une condition à respecter : celle-là doit permettre d'assurer le piégeage d'une bonne part des contaminants de l'air.
Rethinking rules and social practices. The design of urban spaces in the post-Covid-19 lockdown

description: In the last months a pandemic has changed the daily life of billions of people. Among the efforts to reduce the impact of the disease, social distancing has had huge consequences and raised may concerns, from the inadequacy of contemporary urban design to the social inequality of national and regional lockdown. This paper focuses on the consequences that this experience is having on the design of urban public and private areas. Everybody admits that our cities are going to change but, beside the first quick adaptation to social distancing, it is unclear how to rethink today’s urban areas. We start from our previous work on the classification of architectural rules and on the study of how creativity is expressed via architectural rules, to discuss the principles and social aspects of newly proposed designs. The motivation for this analysis is to investigate and raise awareness of the consequences of changes in social practices: given that we are in need for new structures and service organization, we can still make choices and should balance the positive and negative aspects of these design alternatives. The community should be aware, as much as possible, of the intrinsic forces that novel solutions exert on our social system and urban environment. This work shows just one way to analyse architectural design, and should be considered as a contribution to a much needed broad and inclusive discussion about how we want urban spaces to be.

title: Selection of muon-antineutrino charged-current single-pion events with boosted decision tree particle identification in the ND280 detector
Creators: name: Penn, Gabriel
Publisher: name: University of Liverpool Repository

description: Tokai to Kamioka (T2K) is a long-baseline neutrino oscillation experiment situated in Japan, studying electron-neutrino appearance in a muon-neutrino beam and thus probing multiple parameters of the Pontecorvo-Maki-Nakagawa-Sakata matrix. A beam of muon-(anti)neutrinos is produced at the J-PARC accelerator complex and sampled by near and far detectors to compare the beam content before and after oscillation. The off-axis near detector, ND280, serves both to characterise signals and backgrounds observed at the far detector, and to measure a variety of neutrino interaction cross-sections on carbon and oxygen nuclear targets. These measurements contribute to our understanding of both neutrino oscillations and the interactions between neutrinos and atomic nuclei. Selecting specific interaction types from the ND280 data requires accurate identification of charged particle tracks, but the conventional cut-based methods perform poorly in many areas. To make full use of the wide array of information available from all of the ND280 subdetectors and thus develop a high-performing particle identification (PID) algorithm, a multivariate analysis approach is necessary, but such a tool has yet to be developed and deployed at T2K. This thesis presents the development of a general-purpose PID tool for charged particle tracks in ND280 using boosted decision trees, and demonstrates its superior classification power compared to the existing PID algorithms currently in use. The tool has been designed to be broadly applicable and outperforms purpose-built conventional PID at identifying each particle type in almost all kinematic regions tested. Furthermore, it has been integrated into a selection algorithm for muon-antineutrino charged-current single-pion events, and found to substantially improve the selection performance. These results demonstrate the power of multivariate PID methods for charged particle tracks in ND280, and strongly motivate their use in future T2K analyses.
