description: Additional radio-frequency (rf) potentials applied to linear multipole traps create extra field nodes in the radial plane which allow one to confine single ions, or strings of ions, in totally rf field-free regions. The number of nodes depends on the order of the applied multipole potentials and their relative distance can be easily tuned by the amplitude variation of the applied voltages. Simulations using molecular dynamics show that strings of ions can be laser cooled down to the Doppler limit in all directions of space. Once cooled, organized systems can be moved with very limited heating, even if the cooling process is turned off.
First Passage Time Distribution of multi-scale stationary Markovian processes

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The aim of this paper is to investigate how the correlation properties of a stationary Markovian stochastic processes affect the First Passage Time distribution. First Passage Time issues are a classical topic in stochastic processes research. They also have relevant applications, for example, in many fields of finance such as the assessment of the default risk for firms' assets. By using some explicit examples, in this paper we will show that the tail of the First Passage Time distribution crucially depends on the correlation properties of the process and it is independent from its stationary distribution. When the process includes an infinite set of time-scales bounded from above, the FPTD shows tails modulated by some exponential decay. In the case when the process is power-law correlated the FPTD shows power-law tails 1/t^(alfa+1)/2 and therefore the moments of the FPTD are finite only when n< (alfa-1)/2. We will also show that such power-law behaviour is not merely due to the fact that the process includes an infinite and unbounded set of time-scales. Rather, the time-scale must enter the FPTD with weights that must be distributed according to a power-law for large time-scales values. Finally, we will give a general result connecting the FPTD of an additive stochastic processes x(t) to the FPTD of a generic process y(t) related by a coordinate transformation y=f(x) to the first one.

Teenage kicks : youth, social class, and hierarchies of taste in Canada’s new drug scene, 1961-1975
Creators: name: Fenn, Robert Samuel
Publisher: name: University of British Columbia

description: This thesis explores the political discourse around the increased use of illicit substances in Canada from 1961 to 1975. In particular, marijuana had been criminalized—along with opium—as a part of a broader move to penalize unwanted Asian workers. At the time, lawmakers could not anticipate that their laws would also fall on a new wave of predominantly affluent and white drug users. When judges began to find more and more middle class young people in their courtrooms, the country found itself in crisis. Using Pierre Bourdieu’s theories of habitus, social class and symbolic violence, this paper argues that affluent marijuana smokers seriously challenged the logic of Canada’s laws by occupying new psychoactive terrain, while simultaneously, establishing a new hierarchy of taste and consumption that disadvantaged other less privileged drug users.

description: Das Verhalten des Kerns in einem Leichtwasserreaktor (LWR) wird von neutronenphysikalischen, thermohydraulischen und thermomechanischen Phänomenen dominiert. Komplexe Rückkopplungsmechanismen verbinden diese physikalischen Bereiche. Einer der aktuellen Tendenzen in der Reaktorphysik ist daher die Implementierung von Multiphysik-Methoden, die diese Wechselwirkungen erfassen, um eine konsistente Beschreibung des Kerns zu liefern. Ein weiterer wichtiger Arbeitsbereich ist die Entwicklung von High-Fidelity-Rechenprogrammen, die die Modellierungsauflösung erhöhen und starke Vereinfachungen eliminieren, die in räumlich homogenisierten Simulationen verwendet werden. Multiphysik- und High-Fidelity-Methoden sind auf die Verfügbarkeit von Hochleistungsrechnern angewiesen, die die Machbarkeit und den Umfang dieser Art von Simulationen begrenzen. Das Ziel dieser Arbeit ist die Entwicklung eines Multiphysik-Simulationssystems, das in der Lage ist, gekoppelte neutronenphysikalische, thermohydraulische und thermomechanische Analysen von LWR-Kernen mit einer High-Fidelity-Methodik durchzuführen. Um dies zu erreichen, wird die Monte-Carlo-Teilchentransportmethode verwendet, um das Verhalten der neutronenphysikalischen Effekte zu simulieren, ohne auf größere physikalische Näherungen zurückzugreifen. Für die Abbrandrechnungen bezüglich des gesamten Kerns, wird eine gebietsbezogene Datenaufteilung der Partikelverfolgung vorgeschlagen und implementiert. Die Kombination der Monte-Carlo-Methode mit der Thermohydraulik auf Unterkanalebene und eine vollständige Analyse des Brennstoffverhaltens aller Brennstäbe beschreibt eine extrem detaillierte Darstellung des Kerns. Die erforderliche Rechenleistung erreicht die Grenzen aktueller Hochleistungsrechner. Auf der Softwareseite wird ein innovativer objektorientierter Kopplungsansatz verwendet, um die Modularität, Flexibilität und Wartbarkeit des Programms zu erhöhen. Die Genauigkeit dieses gekoppelten Systems von drei Programmen wird mit experimentellen Daten von zwei in Betrieb befindlichen Kraftwerken, einem Pre-Konvoi DWR und dem Temelín II WWER-1000 Reaktor, bewertet. Für diese beiden Fälle werden die Ergebnisse der Abbrandrechnung des gesamten Kerns anhand von Messungen der kritischen Borkonzentration und des Brennstabneutronenflusses validiert. Diese Simulationen dienen der Darstellung der hochmodernen Modellierungsfähigkeiten des entwickelten Werkzeugs und zeigen die Durchführbarkeit dieser Methodik für industrielle Anwendungen.

description: Lithium abundances are presented and discussed for 70 members of the 50 Myr old open cluster alpha Per. More than half of the abundances are from new high-resolution spectra. The Li abundance in the F-type stars is equal to its presumed initial abundance confirming previous suggestions that pre-main sequence depletion is ineffective for these stars. Intrinsic star-to-star scatter in Li abundance among these stars is comparable to the measurement uncertainties. There is marginal evidence that the stars of high projected rotational velocity v sini follow a different abundance vs temperature trend to the slow rotators. For stars cooler than about 5500 K, the Li abundance declines steeply with decreasing temperature and there develops a star-to-star scatter in the Li abundance. This scatter is shown to resemble the well documented scatter seen in the 70 Myr old Pleiades cluster. The scatter appears to be far less pronounced in the 30 Myr clusters which have been studied for Li abundance.

description: We make frequentist analyses of the CMSSM, NUHM1, VCMSSM and mSUGRA parameter spaces taking into account all the public results of searches for supersymmetry using data from the 2010 LHC run and the Xenon100 direct search for dark matter scattering. The LHC data set includes ATLAS and CMS searches for jets + ETslash events (with or without leptons) and for the heavier MSSM Higgs bosons, and the upper limit on bs to mu mu including data from LHCb as well as CDF and D0. The absences of signals in the LHC data favour somewhat heavier mass spectra than in our previous analyses of the CMSSM, NUHM1 and VCMSSM, and somewhat smaller dark matter scattering cross sections, all close to or within the pre-LHC 68% CL ranges, but do not impact significantly the favoured regions of the mSUGRA parameter space. We also discuss the impact of the Xenon100 constraint on spin-independent dark matter scattering, stressing the importance of taking into account the uncertainty in the pi-nucleon sigma term, that affects the spin-independent scattering matrix element, and we make predictions for spin-dependent dark matter scattering. Finally, we discuss briefly the potential impact of the updated predictions for sparticle masses in the CMSSM, NUHM1, VCMSSM and mSUGRA on future e+ e- colliders.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A recent work by Dubeibe et al. [Phys. Rev. D 75, 023008 (2007)] stated that chaos phenomenon of test particles in gravitational field of rotating neutron stars which are described by Manko, Sanabria-Gomez, and Manko (Manko et al.) metric can only occur when the stars have oblate deformation. But the chaotic motions they found are limited in a very narrow zone which is very close to the center of the massive bodies. This paper argues that this is impossible because the region is actually inside of the stars, so the motions cannot exist at this place. In this paper, we scan all parameters space and find chaos and unstable fixed points outside of stars with big mass-quadrupole moments. The calculations show that chaos can only occur when the stars have prolate deformation. Because real deformation of stars should be oblate, all orbits of test particles around the rotating neutron stars described by Manko et al. solutions are regular. The case of nonzero dipolar magnetic moment has also been taken into account in this study.

description: Antiferromagnetic (AF) nanostructures from Co3O4, CoO and Cr2O3 were prepared by the nanocasting method and were characterized magnetometrically. The field and temperature dependent magnetization data suggests that the nanostructures consist of a core-shell structure. The core behaves as a regular antiferromagnet and the shell as a two-dimensional diluted antiferromagnet in a field (2d DAFF) as previously shown on Co3O4 nanowires [Benitez et al., Phys. Rev. Lett. 101, 097206 (2008)]. Here we present a more general picture on three different material systems, i.e. Co3O4, CoO and Cr2O3. In particular we consider the thermoremanent (TRM) and the isothermoremanent (IRM) magnetization curves as "fingerprints" in order to identify the irreversible magnetization contribution originating from the shells. The TRM/IRM fingerprints are compared to those of superparamagnetic systems, superspin glasses and 3d DAFFs. We demonstrate that TRM/IRM vs. H plots are generally useful fingerprints to identify irreversible magnetization contributions encountered in particular in nanomagnets.

description: The advent of precise measurements of the cosmic microwave background (CMB) anisotropies has motivated correspondingly precise calculations of the cosmic recombination history. Cosmic recombination proceeds far out of equilibrium because of a "bottleneck" at the $n=2$ level of hydrogen: atoms can only reach the ground state via slow processes: two-photon decay or Lyman-$α$ resonance escape. However, even a small primordial abundance of molecules could have a large effect on the interline opacity in the recombination epoch and lead to an additional route for hydrogen recombination. Therefore, this paper computes the abundance of the H$_2$ molecule during the cosmic recombination epoch. Hydrogen molecules in the ground electronic levels X$^1Σ^+_g$ can either form from the excited H$_2$ electronic levels B$^1Σ^+_u$ and C$^1Π_u$ or through the charged particles H$_2^+$, HeH$^+$ and H$^-$. We follow the transitions among all of these species, resolving the rotational and vibrational sub-levels. Since the energies of the X$^1Σ^+_g$--B$^1Σ^+_u$ (Lyman band) and X$^1Σ^+_g$-C$^1Π_u$ (Werner band) transitions are near the Lyman-$α$ energy, the distortion of the CMB spectrum caused by escaped H Lyman-line photons accelerates both the formation and the destruction of H$_2$ due to this channel relative to the thermal rates. This causes the populations of H$_2$ molecules in X$^1Σ^+_g$ energy levels to deviate from their thermal equilibrium abundances. We find that the resulting H$_2$ abundance is $10^{-17}$ at $z=1200$ and $10^{-13}$ at $z=800$, which is too small to have any significant influence on the recombination history.

description: In the framework of the Littlest Higgs Model with T-parity (LHT), we study the contributions of the new particles to $Zb\bar{b}$ couplings at one-loop level. Based on these results, we further study the branching ratio $R_{b}$ and the unpolarized forward-backward asymmetry ${A_{FB}^{b}}$. We find that the correction of the new particles to $Zb\bar{b}$ couplings is mainly on the left-handed coupling and has small part of the parameter space to alleviate the deviation between theoretical predictions and experimental values. The precision measurement value of $R_{b}$ can give severe constraints on the relevant parameters. The constraints from the precision measurement value of ${A_{FB}^{b}}$ are very weak.

We introduce bistochastic QFA (MM-BQFA), a model which generalizes both Nayak's enhanced QFA and DH-PRA. We apply tools from algebraic automata theory and systems of linear inequalities to give a complete characterization of R1 languages recognized by all these models. We also find that "forbidden constructions" known so far do not include all of the languages that cannot be recognized by measure-many QFA.

description: La variation qui existe dans les populations naturelles s’exprime par des différences phénotypiques entre individus qui concernent tant les performances physiologiques et les comportements que les stratégies démographiques. En biologie des populations, il est pourtant classique de ne considérer que des moyennes spécifiques ou populationnelles et donc de traiter la variation interindividuelle comme un bruit aléatoire autour de la moyenne. Des développements récents de l’écologie évolutive fournissent un cadre théorique pour comprendre l’émergence et le maintien de phénotypes complexes, et ainsi expliquer la variation et la covariation de traits physiologiques, comportementaux et démographiques. Mes travaux de recherche s’inscrivent dans cette problématique de description, compréhension et modélisation de la variation interindividuelle en écologie des populations. Dans ce mémoire, je propose une synthèse de l’état de nos connaissances au sujet des rétroactions entre la variation interindividuelle, prise dans toutes ses dimensions, et la dynamique des populations naturelles, définie comme l’ensemble des trajectoires suivies par une population dans un environnement variable dans l’espace et dans le temps. Après avoir défini le concept d'individu biologique, j'explique les méthodes et les difficultés rencontrées dans la quantification des différences interindividuelles. Je décris nos travaux démontrant comment les interactions entre génétique, environnement et développement façonnent l’expression de phénotypes complexes en populations naturelles, tels que la taille corporelle et les performances locomotrices, les comportements ou l’histoire de vie. Une synthèse des différentes approches théoriques développées pour quantifier les effets de la variation interindividuelle sur la dynamique des populations est conduite. Je l'illustre à l'aide de nos études sur les variations d’histoire de vie entre cohortes, la structuration en taille de la population et la densité-dépendance. Les implications pour l’étude des petites populations en déclin ou au bord de l’extinction et pour la stabilité des populations autour de leur équilibre sont discutées. Une bonne compréhension de la variation interindividuelle est utile non seulement en biologie des populations mais aussi à un niveau hiérarchique supérieur en écologie des communautés et des écosystèmes.

description: We report the theoretical and experimental demonstration of pattern formation in acoustics. The system is an acoustic resonator containing a viscous fluid. When the system is driven by an external periodic force, the ultrasonic field inside the cavity experiences different pattern-forming instabilities leading to the emergence of periodic structures. The system is also shown to possess bistable regimes, in which localized states of the ultrasonic field develop. The thermal nonlinearity in the viscous fluid, together with the far-from-equilibrium conditions, are is the responsible of the observed effects.
A recipe for an effective selection of promising candidates for high-temperature superconductors among binary hydrides

description: Recent research on compressed binary hydrides have unveiled the potential for achieving superconductivity at near-room-temperature. Nevertheless, the available decision-making procedures standing behind the selection of constituent elements that may potentially exhibit high values of critical temperature ($T_c$) are far from optimal. In other words, a lot of experimental and numerical effort is wasted on exploring unpromising compounds. By conducting a deep study of a database containing over $580$ binary hydride superconductors, we were able to observe some interesting relationships between $T_c$ and selected physico-chemical properties of examined compounds. Among studied parameters, the ratio of the sum of the molecular weight of heavier atoms to the total mass of all hydrogen atoms in the chemical formula of hydride ($M_X/M_H$) was found to be the most valuable indicator that can help to screen for new promising superconductor candidates. This is because the highest $T_c$ requires the lowest $M_X/M_H$ ratio. Statistical analysis indicates a $28\%$ chance of finding $T_c > 200$ K within $0 < M_X/M_H < 15$. It is expected that these findings will not only allow for more efficient use of resources by improving future superconductor candidates selection but also they will accelerate ongoing experimental and numerical research that should bring new exciting discoveries in a much shorter time.

A perspective on the Naxalite insurgency in Jharkhand and Bihar : going beyond the grievance argument
Creators: name: Prasad, Deborah Y. J.
Publisher: name: University of British Columbia
Year: 2015

description: This thesis examines a form of left wing extremism called the Naxalite, or Maoist insurgency in the Eastern Indian states of Jharkhand and Bihar. Deemed the biggest internal security threat to India by Prime Minister Manmohan Singh in 2004, this low level insurgency has been plaguing the country for over fifty years. To date, the government of India has used a two pronged security and development approach to combat the problem, but it still remains a serious issue. This thesis examines why the Naxalite movement has essentially been restricted to the geographic area referred to as the “Red Corridor”, and also examines why the insurgency has not yet been resolved. A majority of the studies approaches this issue as either a law and order problem or a development problem; however, this thesis scrutinizes the nature and motives of the insurgents themselves. The purpose of this study was to suggest the idea that the insurgents responsible for the violence of the Naxalite insurgency are more often motivated by greed of opportunity and economic gain, rather than genuine grievances. This is not to say that genuine grievances do not exist in this insurgency, rather it is merely to say that it is not a fuelling factor for violence. Lastly, this thesis examines the lack of monitoring and gaps in policy implementation for counterinsurgency, and finds that it is the lack of cognizant monitoring, rather than lack of policy, which has contributed to lack of the resolution of the conflict.

The NGC 1023 Galaxy Group: An Anti-Hubble Flow?

description: We discuss recently published data indicating that the nearby galaxy group NGC 1023 includes an inner virialized quasi-stationary component and an outer component comprising a flow of dwarf galaxies falling toward the center of the system. The inner component is similar to the Local Group of galaxies, but the Local Group is surrounded by a receding set of dwarf galaxies forming the very local Hubble flow, rather than a system of approaching dwarfs. This clear difference in the structures of these two systems, which are very similar in other respects, may be associated with the dark energy in which they are both imbedded. Self-gravity dominates in the Local Group, while the anti-gravity produced by the cosmic dark-energy background dominates in the surrounding Hubble flow. In contrast, self-gravity likewise dominates throughout the NGC 1023 Group, both in its central component and in the surrounding Santi-Hubble flow. The NGC 1023 group as a whole is apparently in an ongoing state of formation and virialization. We may expect that there exists a receding flow similar to the local Hubble flow at distances of 1.4-3 Mpc from the center of the group, where anti-gravity should become stronger than the gravity of the system.

description: Magnetic and NMR relaxivity properties of γ-Fe2O3 nanoparticles embedded into the walls of polyelectrolyte multilayer capsules and freely dispersed in a sodium borate buffer solution have been investigated. The different geometric distribution of both configurations provides the opportunity to study the relationship of water accessibility and magnetic properties of particles on the NMR relaxivity. Changes in their blocking temperature and average dipolar field were modeled as a function of packing fraction in the ensemble of free and entrapped nanoparticles. For free nanoparticles with relatively low concentration, relaxivity values increase with packing fraction according to an increase in the dipolar field and larger water accessibility. However for embedded NPs in the capsule wall, packing fractions should be limited to optimise the efficiency of this system as magnetic resonance imaging (MRI) contrast agent.

description: We present high resolution near-infrared spectra of $β$ Pictoris - a nearby young star with a debris disk. Fundamental low-J CO absorption lines are detected and strict upper limits are placed on the flux of v=2-1 low-J CO emission lines. The limit on the UV fluorescent emission flux in the v=2-1 lines is used to place a tight constraint on the inner extent of the CO gas. Assuming \ion{H}{1} is the primary collision partner, the subthermal population of the low-J v=0 rotational levels constrains the density of the gas in the disk to $n_{\rm H} = (2.5^{+7.1}_{-1.2})\times10^5$ cm$^{-3}$. If the distribution of hydrogen follows that of the other metals in the disk, we find that the mass of the gas in the disk is $(0.17^{+0.47}_{-0.08})$ M$_\earth$. We compare this mass to the gas mass necessary to brake the metals in the disk through ion-neutral reactions.

description: We introduce and investigate notions of persistent homology for p-groups and for coclass trees of p-groups. Using computer techniques we show that persistent homology provides fairly strong homological invariants for p-groups of order at most 81. The strength of these invariants, and some elementary theoretical properties, suggest that persistent homology may be a useful tool in the study of prime-power groups.

Inferring user cognitive abilities from eye-tracking data
Creators: name: Wu, Ming-An
Publisher: name: University of British Columbia

description: User-adaptive visualization can provide intelligent personalization to aid the user in the information processing. The adaptations, in the form as simple as helpful highlighting, are applied based on user’s characteristics and preferences inferred by the system. Previous work has shown that binary labels of user’s cognitive abilities relevant for processing information visualizations could be predicted in real time, by leveraging user gaze patterns collected via a non-intrusive eye-tracking device. The classification accuracies reported were in the 59–65% range, which is statistically more accurate than a majority-class classifier, but not of great practical significance. In this thesis, we expand on previous work by showing that significantly higher accuracies can be achieved by leveraging summative statistics on a user’s pupil size and head distance to the screen measurements, also collected by an eye tracker. Our experiments show that these results hold for two datasets, providing evidence of the generality of our findings. We also explore the sequential nature of gaze movement by extracting common substring patterns and using the frequency of these patterns as features for classifying user’s cognitive abilities. Our sequence features are able to classify more accurately than the majority-class baseline, but unable to outperform our best classification model with the summative eye-tracking features.
Magnetic excitations in the XY-pyrochlore antiferromagnet Er$_2$Ti$_2$O$_7$

description: The XY-pyrochlore antiferromagnet \ETO\ is studied by heat capacity measurements and electron spin resonance spectroscopy performed on single crystal samples. The magnetic phase diagrams are established for two directions of applied field, $H\parallel [100]$ and $H\parallel [111]$. In the magnetically ordered phase observed below $T_N=1.2$ K, the magnetic excitation spectrum consists of a Goldstone mode acquiring an isotropic gap in an applied field, and another mode with a gap softening in the vicinity of a field-induced phase transition. This second-order transition takes place at a critical field $H_c$ above which the magnetization process is accompanied by a canting of the magnetic moments off their local "easy-planes". The specific heat curves for $H\parallel [100]$ ($H\gg H_c$) are well described by a model presuming a single dispersionless excitation mode with the energy gap obtained from the spectroscopic measurements.

description: This document is the report of the activities performed in the frame of WP 2251-3 of the IDEAS-QA4EO WPs-2250-2251 “DOAS-BO: Towards a new FRM4DOAS-compliant site’’. The WP 2251-3 is centered on the inter-comparison campaign performed at La Sapienza University in Rome, part of the BAQUNIN supersite. In May 2021, the ISAC-CNR institute acquired (in the frame of a national funded project “Programma biennale degli investimenti del CNR”) a new MAX-DOAS system, the SkySpec-2D. This system took part in several FRM4DOAS inter-comparison campaigns (e.g., CINDI) and full fills all the FRM4DOAS requirements. The SkySpec-2D final destination is the San Pietro Capofiume (BO) “Giorgio Fea” ISAC-CNR observatory in the Po Valley. Due to its full compliance with FRM4DOAS requirements and its more advanced technology, we decided to use the SkySpec-2D instrument instead of the TROPOGAS for the BAQUNIN campaign. However, before traveling to Rome, the SkySpec-2D was employed in an inter-comparison campaign with the TROPOGAS instrument in Bologna, in order to compare the performances of the two MAX-DOAS systems in the same conditions. In this report, we briefly describe the SkySpec-2D system and report the results of the Bologna and BAQUNIN inter-comparison campaigns.
Early intervention with Indigenous families and children in British Columbia : a critical inquiry
Creators: name: Gerlach, Alison Jayne
Publisher: name: University of British Columbia

description: Improving the health of Indigenous children and fostering health equity requires a radical shift beyond prevailing health care approaches. Early child development (ECD) and intervention programs are increasingly recognized for their potential in promoting children’s health and well-being, and appear to be ideally positioned to play a vital role in fostering child health equity. Currently, there is a lack of research on early intervention (EI) programs in the context of Indigenous families and children in Canada. The purpose of this qualitative study was to generate knowledge on how an urban-based EI home-visiting program for Indigenous families and children in BC, known as the Aboriginal Infant Development Program (AIDP), influences families and children’s health and well-being, and is responsive to health and social inequities affecting families and children experiencing social disadvantages. This inquiry was informed by critical theoretical perspectives and undertaken in collaboration with the AIDP. Ethnographic methods of data collection were used to obtain the perspectives of: Indigenous caregivers (n=10) and Elders involved in AIDPs (n=4), AIDP workers (n=18), and administrative leaders of organizations that hosted AIDPs (n=3). Findings demonstrate: (a) a relational perspective of ECD that emphasizes how family well-being and children’s health equity are inextricably connected, and shaped by intersecting structural inequities; (b) how AIDP workers influence family well-being and foster child health equity by: (i) contextually tailoring their programs for female-led single-parent families in urban contexts, and (ii) reframing the EI process so that it is responsive to women’s agency and self-identified priorities, which are frequently centered on accessing determinants of health and navigating the health care and child welfare systems; (c) how locating AIDPs in multi-service organizational hubs enhances a relational orientation to EI, and (d) how AIDP workers traverse a contested ECD landscape and an increasingly complex relationship with the child welfare system. This knowledge will be used to inform and enhance AIDP practices, policies, and education. These findings are applicable to a broad range of ECD and health care disciplines, including occupational therapists, and EI programs that serve Indigenous and non-Indigenous children who live with social disadvantages that stem from structural inequities.

description: The existence of a "bonus" U(1) level-one Yangian symmetry of N=4 super-Yang-Mills has recently been proposed. We provide evidence for this proposal by constructing the BRST-invariant nonlocal charge in the pure spinor sigma model corresponding to this bonus level-one symmetry. We also construct analogous charges for bonus U(1) symmetries at all odd levels of the Yangian.
