description: Microlensing events are usually selected among single-peaked non-repeating light curves in order to avoid confusion with variable stars. However, a microlensing event may exhibit a second microlensing brightening episode when the source or/and the lens is a binary system. A careful analysis of these repeating events provides an independent way to study the statistics of wide binary stars and to detect extrasolar planets. Previous theoretical studies predicted that 0.5 - 2 % of events should repeat due to wide binary lenses. We present a systematic search for such events in about 4000 light curves of microlensing candidates detected by the Optical Gravitational Lensing Experiment (OGLE) towards the Galactic Bulge from 1992 to 2007. The search reveals a total of 19 repeating candidates, with 6 clearly due to a wide binary lens. As a by-product we find that 64 events (~2% of the total OGLE-III sample) have been miss-classified as microlensing; these miss-classified events are mostly nova or other types of eruptive stars. The number and importance of repeating events will increase considerably when the next-generation wide-field microlensing experiments become fully operational in the future.

description: Spectral feature index diagrams with integrated globular clusters and simple stellar population models often show that some clusters have weak H beta, so weak that even the oldest models cannot match the observed feature depths. In this work, we rule out the possibility that abundance mixture effects are responsible for the weak indices unless such changes operate to cool the entire isochrone. We discuss this result in the context of other explanations, including horizontal branch morphology, blue straggler populations, and nebular or stellar emission fill-in, finding a preference for flaring in M giants as an explanation for the H beta anomaly.

description: Many studies simulates the machining process by using a single degree of freedom spring-mass sytem to model the tool stiffness, or the workpiece stiffness, or the unit tool-workpiece stiffness in modelings 2D. Others impose the tool action, or use more or less complex modelings of the efforts applied by the tool taking account the tool geometry. Thus, all these models remain two-dimensional or sometimes partially three-dimensional. This paper aims at developing an experimental method allowing to determine accurately the real three-dimensional behaviour of a machining system (machine tool, cutting tool, tool-holder and associated system of force metrology six-component dynamometer). In the work-space model of machining, a new experimental procedure is implemented to determine the machining system elastic behaviour. An experimental study of machining system is presented. We propose a machining system static characterization. A decomposition in two distinct blocks of the system "Workpiece-Tool-Machine" is realized. The block Tool and the block Workpiece are studied and characterized separately by matrix stiffness and displacement (three translations and three rotations). The Castigliano's theory allows us to calculate the total stiffness matrix and the total displacement matrix. A stiffness center point and a plan of tool tip static displacement are presented in agreement with the turning machining dynamic model and especially during the self induced vibration. These results are necessary to have a good three-dimensional machining system dynamic characterization.

description: The Stoner-Wohlfarth astroid is a fundamental object in magnetism. It separates regions of the magnetic field space with two stable magnetization equilibria from those with only one stable equilibrium and it characterizes the magnetization reversal of nano-magnets induced by applied magnetic fields. On the other hand, it was recently demonstrated that transfer of spin angular momentum from a spin-polarized current provides an alternative way of switching the magnetization. Here, we examine the astroid of a nano-magnet with uniaxial magnetic anisotropy under the combined influence of applied fields and spin-transfer torques. We find that spin-transfer is most efficient at modifying the astroid when the external field is applied along the easy-axis of magnetization. On departing from this situation, a threshold current appears below which spin-transfer becomes ineffective yielding a current-induced dip in the astroid along the easy-axis direction. An extension of the Stoner-Wohlfarth model is outlined which accounts for this phenomenon.

Proust et Mandel'shtam a la recherche du temps perdu : rapprochement des méthodes employées par ces deux écrivains dans leurs oeuvres
Creators: name: Iverson, Anne Mary Guilhamoulie
Publisher: name: University of British Columbia
Year: 2011

description: Deux écrivains contemporains, l'un francais, l'autre russe soviétique, ont ressenti vivement le passage inexorable du temps. Ils se sont mis à cueillir les souvenirs et les impressions de l'enfance afin de recréer le "paradis de l'enfance" et ainsi figer la vie passagère et retrouver "le temps perdu". Marcel Proust (1871 - 1922), auteur français du magnifique roman A la Recherche du temps perdu, et Ossip Emilievich Mandel'shtam (1891 - 1938), auteur russe du chef-d'oeuvre Shum Vremeni (Le Bruit du temps), se sont voués, chacun de son côté, à mettre à jour leurs premières sensations et impressions. Dans ces deux oeuvres plus ou moins autobiographiques, le Temps se montre comme personnage principal. Chez tous les deux écrivains nous trouvons un culte passionné des valeurs intellectuelles, une sensibilité développée à l'extrême, un sens du passé et une préoccupation soucieuse de sa conservation. L'objet de cette thèse est, premièrement, de faire plusieurs analogies entre les ambiances familiales et intellectuelles des deux écrivains, entre leurs caractères également sensibles et impressionnables, et entre leurs sentiments et idées philosophiques et psychologiques. On peut faire une analyse détaillée des techniques individuelles qui ont joué un rôle si important dans l'oeuvre de chacun, et, ensuite, rapprocher les méthodes employées pour réaliser leurs tentatives surhumaines, c'est-à-dire, les façons dont chacun a réussi à retrouver le temps perdu. La recherche du réel chez Mandel'shtam, comme chez Proust, commence avec les souvenirs d'enfance, ainsi qu'avee les premières impressions mystérieuses. Tandis que Proust affirme à tout instant la prédominance de la perception affective en cherchant un rapport mystique avec l'Absolu, Mandel'shtam affirme la suprématie de l'élément logique et concret dans l'oeuvre. C'est la capacité de Mandel'shtam, selon M. Gleb Struve, de contenir le général dans le concret qui donne la valeur particulière a son impression du "temps perdu". L'ouvrage de Mandel'shtam, comme celui de Proust, montre un sens historique et un sentiment vif du temps vécu. Leurs oeuvres géniales incarnent leur visions personnelles de la vie temporelle et la vie extra-temporelle. En s'élevant au-dessus du temps, Proust et Mandel'shtam ont pénétré1 le mystère de l'éternel—ils sont arrivés à l'essence de la vie. Tous deux ont réussi définitivement à conjurer et, ensuite, enserrer à jamais dans les toiles fines de leurs oeuvres le Temps élusif et passager.

description: The geometry of convex domains in Euclidean space plays a central role in several branches of mathematics: functional and harmonic analysis, the theory of PDE, linear programming and, increasingly, in the study of other algorithms in computer science. High-dimensional geometry, both the discrete and convex branches of it, has experienced a striking series of developments in the past 10 years. Several examples were presented at this meeting, for example the work of Rudelson et al. on conjunction matrices and their relation to conﬁdential data analysis, that of Litvak et al. on remote sensing and a series of results by Nazarov and Ryabogin et al. on Mahler’s conjecture for the volume product of domains and their polars.

description: The escaping set of a transcendental entire or meromorphic function consists of all points which tend to inﬁnity under iteration. Its importance in transcendental dynamics has increased signiﬁcantly in recent years. The workshop focussed on a study of this set.

Publisher: name: Zürich : EMS Publ. House
Year: 2009

subject: 510

description: The mini-workshop was devoted to the spectral analysis of random Schr¨dinger-type operators. While this topic has been intensively studo ied by physicists and mathematicians for several decades, more recently there has been particular attention devoted to models where the random parameters enter the model in a non-monotone or non-linear way. Most of the established methods applied for random operators, in fact, hinge on the presence of monotonicity w. r. t. randomness. Thus the treatment of non-monotone models forces a deeper analysis of the structure of random Hamiltonians and, in particular, the interplay of the kinetic and the potential energy parts.

description: The equilibrium density distribution and thermodynamic properties of a Lennard-Jones fluid confined to nano-sized spherical cavities at constant chemical potential was determined using Monte Carlo simulations. The results describe both a single cavity with semipermeable walls as well as a collection of closed cavities formed at constant chemical potential. The results are compared to calculations using classical Density Functional Theory (DFT). It is found that the DFT calculations give a quantitatively accurate description of the pressure and structure of the fluid. Both theory and simulation show the presence of a ``reverse'' liquid-vapor transition whereby the equilibrium state is a liquid at large volumes but becomes a vapor at small volumes.

description: The workshop aimed at developing interactions between researchers from quantum information theory and from asymptotic geometric analysis.

In these spaces, phenomena such as concentration of measure become prominent and may invalidate our low-dimensional intuition.

description: This data set is a description of a novel analogue modelling method used to run lithospheric-scale tectonic models, and to uniquely monitor these models through X-Ray CT-scanning techniques at the Tectonic Modelling Lab of the University of Bern (Switzerland). It includes information on the model set-up and model materials, and includes a step-by-step description of the general modelling procedure. A first application of this novel procedure, for the simulation of lithospheric scale rifting processes can be found in Zwaan & Schreurs (2023a) in Tectonics, with supplementary data publicly available via GFZ Data Services (Zwaan & Schreurs 2023b). The results of this work prove the feasibility of the method, and opens the door to a broad variety of new tectonic modelling studies.

description: We present an analytical treatment of coherent excitation of a Two-Level Atom driven by a far-off resonant classical field. A class of pulse envelope is obtained for which this problem is exactly solvable. The solutions are given in terms of Heun function which is a generalization of the Hypergeometric function. The degeneracy of Heun to Hypergeometric equation can give all the exactly solvable pulse shapes of Gauss Hypergeometric form, from the generalized pulse shape obtained here. We discuss the application of the results obtained to the generation of XUV.

description: A new technique is described by which light-induced gauge potentials allow systems of ultra-cold neutral atoms to behave like charged particles in a magnetic field. Here, atoms move in a uniform laser field with a spatially varying Zeeman shift and experience an effective magnetic field. This technique is applicable for atoms with two or more internal ground states. Finally, an explicit model of the system using a single-mode 2D Gross-Pitaevskii equation yields the expected vortex lattice.

description: We investigate the anisotropic triangular lattice that interpolates from decoupled one-dimensional chains to the isotropic triangular lattice and has been suggested to be relevant for various quasi-two-dimensional materials, such as Cs$_2$CuCl$_4$ or $κ$-(ET)$_2$Cu$_2$(CN)$_3$, an organic material that shows intriguing magnetic properties. We obtain an excellent accuracy by means of a novel representation for the resonating valence bond wave function with both singlet and triplet pairing. This approach allows us to establish that the magnetic order is rapidly destroyed away from the pure triangular lattice and incommensurate spin correlations are short range. A non-magnetic spin liquid naturally emerges in a wide range of the phase diagram, with strong one-dimensional character. The relevance of the triplet pairing for $κ$-(ET)$_2$Cu$_2$(CN)$_3$ is also discussed.

Role of temperature effects in the phenomenon of ultraslow electromagnetic pulses in Bose-Einstein condensates of alkali-metal atoms

description: We study the temperature dependence of optical properties of dilute gases of alkali-metal atoms in the state with Bose-Einstein condensates. The description is constructed in the framework of the microscopic approach that is based on the Green-functions formalism. We find the expressions for the scalar Green functions describing a linear response of a condensed gas to a weak external electromagnetic field (laser). It is shown that these functions depend on the temperature, other physical properties of a system, and on the frequency detuning of a laser. We compare the relative contributions of the condensate and non-condensate particles in the system response. The influence of the temperature effects is studied by the example of two- and three-level systems. We show that in these cases, which are most commonly realized in the present experiments, the group velocity and the absorption rate of pulses practically do not depend on the gas temperature in the region from the absolute zero to the critical temperature. We discuss also the cases when the temperature effects can play a significant role in the phenomenon of slowing of electromagnetic pulses in a gas of alkali-metal atoms with Bose-Einstein condensates.

description: We investigate the thermal Casimir interaction between two magnetodielectric plates made of real materials. On the basis of the Lifshitz theory, it is shown that for diamagnets and for paramagnets in the broad sense (with exception of ferromagnets) the magnetic properties do not influence the magnitude of the Casimir force. For ferromagnets, taking into account the realistic dependence of magnetic permeability on frequency, we conclude that the impact of magnetic properties on the Casimir interaction arises entirely from the contribution of the zero-frequency term in the Lifshitz formula. The computations of the Casimir free energy and pressure are performed for the configurations of two plates made of ferromagnetic metals (Co and Fe), for one plate made of ferromagnetic metal and the other of nonmagnetic metal (Au), for two ferromagnetic dielectric plates (on the basis of polystyrene), and for a ferromagnetic dielectric plate near a nonmagnetic metal plate. The dielectric permittivity of metals is described using both the Drude and the plasma model approaches. It is shown that the Casimir repulsion through the vacuum gap can be realized in the configuration of a ferromagnetic dielectric plate near a nonmagnetic metal plate described by the plasma model. In all cases considered, the respective analytical results in the asymptotic limit of large separations between the plates are obtained. The impact of the magnetic phase transition through the Curie temperature on the Casimir interaction is considered. In conclusion, we propose several experiments allowing to determine whether the magnetic properties really influence the Casimir interaction and to independently verify the Drude and plasma model approaches to the thermal Casimir force.

description: The UPOU Office of Student Affairs or OSA Examination Services Program has begun administering exams in either online non proctored or online proctored double set up due to the ongoing COVID-19 pandemic (UPOU OSA, 2020). The project, entitled TestTime, is an online examination system that will help UPOU provide exams to their students in a streamlined manner without sacrificing exam integrity. The online examination system has the functionality to register users such as students and teachers. If the user is a teacher, the system has the functionality to add/edit/delete examinations as well as to add/edit/delete grades. If the user is a student, the system has the functionality to browse, read, take, and review examination questions and submit examination answers, as well as to submit answers for clarifications and regrading. It also allows a user who is either a teacher or faculty member to use a proctoring system while the student is taking an exam. This includes a webcam or screen capture of the student during the exam that allows the proctor to monitor the student in real time. The project includes a review of online examination systems and existing alternatives. The results were evaluated by gathering the input of students on the usability of the system’s functionality and features. Recommendations on how the system can be improved with further development were also included.

description: The value-at-risk of a delta-gamma approximated derivatives portfolio can be computed by numerical integration of the characteristic function. However, while the choice of parameters in any numerical integration scheme is paramount, in practice it often relies on ad hoc procedures of trial and error. For normal and multivariate $t$-distributed risk factors, we show how to calculate the necessary parameters for one particular integration scheme as a function of the data (the distribution of risk factors, and delta and gamma) \emph{in order to satisfy a given error tolerance}. This allows for implementation in a fully automated risk management system. We also demonstrate in simulations that the method is significantly faster than the Monte Carlo method, for a given error tolerance.

description: The objective of D5.4 (the Data Management Plan) is to describe what data the SPOT project will collect and proceed, whether and how it will be exploited or made accessible for verification and reuse and how it will be curated and preserved after the end of the project. Data Management Plans (DMPs) are a key element of good data management. A DMP describes the data management life cycle for the data to be collected, processed and/or generated by a Horizon 2020 project. As part of making research data findable, accessible, interoperable and reusable (FAIR), a DMP should include information on: • the handling of research data during & after the end of the project, • what data will be collected, processed and/or generated, • which methodology & standards will be applied, • whether data will be shared/made open access, and • how data will be curated & preserved (including after the end of the project). A DMP is required for all projects participating in the extended ORD pilot unless they are opt-out of the ORD pilot. However, projects that opt-out is still encouraged to submit a DMP voluntarily.
The early high-energy afterglow emission from Short GRBs

description: We calculate the high energy afterglow emission from short Gamma-Ray Bursts (SGRBs) in the external shock model. There are two possible components contributing to the high energy afterglow: the electron synchrotron emission and the synchrotron self-Compton (SSC) emission. We find that for typical parameter values of SGRBs, the early high-energy afterglow emission in 10 MeV-10 GeV is dominated by the synchrotron emission. For a burst occurring at redshift z =0.1, the high-energy emission can be detectable by Fermi LAT if the blast wave has an energy E>=10^51 ergs and the fraction of energy in electrons is ε_e>=0.1 . This provides a possible explanation for the high energy tail of SGRB 081024B.

Mini-Workshop: Product Systems and Independence in Quantum Dynamics

Subjects: subject: Konferenzschrift
subject: 510

description: Quantum dynamics, both reversible (i.e., closed quantum systems) and irreversible (i.e., open quantum systems), gives rise to product systems of Hilbert spaces or, more generally, of Hilbert modules. When we consider reversible dynamics that dilates an irreversible dynamics, then the product system of the latter is equal to the product system of the former (or is contained in a unique way). Whenever the dynamics is on a proper subalgebra of the algebra of all bounded operators on a Hilbert space, in particular, when the open system is classical (commutative) it is indispensable that we use Hilbert modules. The product system of a reversible dynamics is intimately related to a ﬁltration of subalgebras that are independent in a state or conditionally independent in a conditional expectation of the reversible system. This has been illustrated in many concrete dilations that have been obtained with the help of quantum stochastic calculus. Here the underlying Fock space or module determines the sort of quantum independence underlying the reversible system. The mini-workshop brought together experts from quantum dynamics, product systems and quantum independence who have contributed to the general theory or who have studied intriguing examples. As the implications of the tight relationship between product systems and independence had so far been largely neglected, we expect from our mini-workshop a strong innovative impulse to this ﬁeld.

local government

description: It is generally agreed that local government has been the weakest of the three main tiers of government in Papua New Guinea since it gained independence in 1975. The reasons for this have been documented in the literature on the decentralisation that was brought into effect by the Organic Law on Provincial Government 1977 (Ghai and Regan 1993; Peasah 1994; May and Regan 1997; May 1999). Although this law gave provincial governments the power to create forms of local government more appropriate to local social circumstances than the model previously advocated by the Australian colonial administration, few took advantage of this opportunity. Whatever the standing of individual councillors within their own communities, the councils themselves generally lacked the financial and human resources required for them to function effectively as organisations engaged in the delivery of public goods and services. This problem is still apparent in most parts of the country. I do not propose to discuss here what could have been done, or should now be done, to improve the performance of this third level of government. Instead, I wish to discuss an institutional arrangement, known as a Special Purposes Authority (SPA), which has been used to perform some of the functions of local government in specific local circumstances. My interest in this subject arose from my recent experience as a consultant engaged in the production of a sustainable development policy for the mining sector that would seek to improve the management of project benefits disbursed to local communities and mine-affected areas (PNG Department of Mining 2003). While one of my aims is to document the potential significance of SPAs for this particular policy framework, I also wish to consider the broader question of how such exceptional institutional arrangements might be an instrument of national policy outside of the mining sector.

description: We study polylithiated molecules as building blocks for hydrogen storage materials, using first-principles calculations. $\clifour$ and $\olitwo$ bind 12 and 10 hydrogen molecules, respectively, with an average binding energy of 0.10 and 0.13 eV, leading to gravimetric densities of 37.8 and 40.3 weight % H. Bonding between Li and C or O is strongly polar and $\hyd$ molecules attach to the partially charged Li atoms without dissociating, which is favorable for (de)hydrogenation kinetics. CLi$_n$ and OLi$_m$ molecules can be chemically bonded to graphene sheets to hinder the aggregation of such molecules.

description: To describe the cumulative incidences of adverse drug reactions (ADRs) associated with disease-modifying anti-rheumatic drugs (DMARDs) in rheumatoid arthritis (RA) patients from real-world data (RWD), using the DREAM-RA registry, and to compare these with incidence frequencies mentioned in the Summary of Product Characteristics (SmPC). All ADRs in patients with recorded use of adalimumab, etanercept, hydroxychloroquine, leflunomide, oral and subcutaneous methotrexate, and sulfasalazine from a single center participating in the DREAM-RA registry (n = 1,098 patients) that were directly sent to the Netherlands Pharmacovigilance Center Lareb were assessed. Cumulative incidences were calculated, described and compared to the most recently revised SmPCs. In total, 14 ADRs (≥5 case reports) associated with the use of one of the included DMARDs were reported with a higher estimated cumulative incidence compared to the SmPC. For hydroxychloroquine and sulfasalazine, 5 ADRs (≥5 case reports) mentioned with an ‘unknown’ incidence in the SmPC were reported as ‘common’ in this study. Although ADR data in the DREAM-RA registry were partly comparable with data in the SmPCs, RWD from this patient registry provided an added value to the currently available information on the incidences of ADRs associated with DMARDs in RA patients as described in SmPCs.

description: Penning trap mass measurements on neutron-deficient Cd isotopes (99-109)Cd have been performed with the ISOLTRAP mass spectrometer at ISOLDE/CERN, all with relative mass uncertainties below 3*10^8. A new mass evaluation has been performed. The mass of 99Cd has been determined for the first time which extends the region of accurately known mass values towards the doubly magic nucleus 100Sn. The implication of the results on the reaction path of the rp process in stellar X-ray bursts is discussed. In particular, the uncertainty of the abundance and the overproduction created by the rp-process for the mass A = 99 is demonstrated by reducing the uncertainty of the proton-separation energy of 100In Sp(100In) by a factor of 2.5.

Digital Transformation Designer: Towards a Comprehensive, Collaborative and Easy-to-Use Modeling Support for Enterprise-level Change Endeavors

description: Established companies intending to leverage digital technologies are required to innovate their ‘legacy’ business models through organizational transformations. Existing modeling support often leaves a ‘white space’ between informal canvas-style models used in the early phases and (semi-)formal aspect models used in the later phases of transformation endeavors. Adopting a Design Science Research approach, this paper presents a semi-formal model that is intended to fill this gap, i. e., to provide easy-to-use support for the heterogeneous stakeholders that participate in early phases of digital transformation endeavors.Being based on the traditional Business Engineering set of models and methods, this comprehensive and collaborative approach was validated together with the digital transformation program manager of a large, international corporation. For supporting analysis, reflection and design tasks that involve a broad range from canvas-style models to enterprise architecture models, four requirements were identified to be central: (remote) collaboration support, a holistic and integrative perspective, an enterprise-level view, and a focus on change. The actual model is comprised of over 20 partial models including popular canvases depicting the transformation program’s content on the strategy-to-IT layers, the enterprise and local level, and in the as-is and to-be state. Demonstration and evaluation were done with practitioners and students of an Executive Master program focusing on digital transformation. Both confirmed the utility of the underlying method and recognized its distinctive features, while capability and IT landscape models were found especially relevant. The method is expected to be applicable for digital transformations beyond the case and also to be projectable to smaller-scaled digital business innovations.

A comparative study of some of the social communication patterns of cormorants and related birds in the Pelecaniformes.
Creators: name: Van Tets, Gerard F.
Publisher: name: University of British Columbia
Year: 2011

description: A comparative study was made of the social communication patterns of Pelecanus erythrorhynchos, P.onocrotalus, P.crispus, P.occidentalis, Morus bassanus, Sula sula, Anhinga anhinga, Phalacrocorax carbo, Ph.auritus, Ph.olivaceust Ph.aristotelis, Ph.urile, Ph.pelagicus, Ph.penicillatus, and Fregata magnificens. It was found that the signal patterns are combinations of a limited number of discrete postures, movements, and sounds, and that they are mainly derivatives from four main sources, locomotion, fighting, nest-building, and begging. The take-off was found to consist of three phases, look, crouch, and leap. From the look and crouch phases the Suloidea have evolved their pre-take off displays, while from the recovery after landing they have evolved their post-landing displays. The pre-take off and post-landing displays are combined into a hop display in this super-family. The sky-pointing, a male-advertising display of Sula, is a derivative of the pre-take off display of Morus and is the origin of the wing-waving as a male-advertising display in Anhinga and Phalacrocorax. The throw-back which is the second part of the male-advertising display of Phalacrocorax arlstotelis is a derivative of the wing-waving display of the other cormorants. Threat displays have evolved into recognition displays in the bill-raising of the Pelecanidae, the head-throwing of Sula sula, the gaping of the Phalacrocoracidae, and into the first part of a male-advertising display, the darting, of Phalacrocorax aristotelis. Nest-indicating displays have evolved from the reaching for nest-material into the reach-bowing of Pelecanus erythrorhynchos, and from nest-worrying movements into the wave-bowing of P.erythrorhynchos, the wing-bowing of Moras, the front-bowing of Sula sula, the quiver-bowing of S.leucogaster and S.dactylatra, the snap-bowing of Anhinga anhinga, the front-bowing of Ph.aristotelis and the gape-bowing of Ph.melanoleucus. The food-begging displays of the chicks have evolved into the pre-landing displays of the Pelecaniformes which in some species also serve as recognition and male-advertising displays on the nest site and in the Sulidae, Anhingidae, Phalacrocoracidae, and Fregatidae accompany the transfer of nest-material between members of a pair at the nest site. The food-begging derived displays also include the aerial displays of Pelecanus erythrorhynchos, the head-wagging of the Sulidae, the kink-throating of the Anhingidae and Phalacrocoracidae, the rattling of the Fregatidae, and the aerial displays of the Phaethontidae. From a comparison of the taxonomic distribution of the form, function and derivation of the social communication patterns in the Pelecaniformes, it was concluded that they reflect the phylogenetic implications of the current systematic classifications of the order.

description: Glioblastoma is thought to originate from neural stem cells (NSCs) of the subventricular zone that acquire genetic alterations. In the adult brain, NSCs are largely quiescent, suggesting that deregulation of quiescence maintenance may be a prerequisite for tumor initiation. Although inactivation of the tumor suppressor p53 is a frequent event in gliomagenesis, whether or how it affects quiescent NSCs (qNSCs) remains unclear. Here, we show that p53 maintains quiescence by inducing fatty-acid oxidation (FAO) and that acute p53 deletion in qNSCs results in their premature activation to a proliferative state. Mechanistically, this occurs through direct transcriptional induction of PPARGC1a, which in turn activates PPARα to upregulate FAO genes. Dietary supplementation with fish oil containing omega-3 fatty acids, natural PPARα ligands, fully restores quiescence of p53-deficient NSCs and delays tumor initiation in a glioblastoma mouse model. Thus, diet can silence glioblastoma driver mutations, with important implications for cancer prevention.
