description: There have been numerous episodes of widespread adoption of improved seed and long-term achievements in the development of the maize seed industry in Sub-Saharan Africa. This summary takes a circumspect view of technical change in maize production. Adoption of improved seed has continued to rise gradually, now representing an estimated 44 percent of maize area in Eastern and Southern Africa (outside South Africa), and 60 percent of maize area in West and Central Africa. Use of fertilizer and restorative crop management practices remains relatively low and inefficient. An array of extension models has been tested and a combination of approaches will be needed to reach maize producers in heterogeneous agricultural environments. Yield growth overall has been 1 percent over the past half-century, although this figure masks the high variability in maize yields, as well as improvements in resistance to disease and abiotic pressures that would have caused yield decline in the absence of maize breeding progress. The authors argue that conducive policies are equally, if not more, important for maize productivity in the region than the development of new technology and techniques. Currently popular, voucher-based subsidies can “crowd out” the private sector and could be fiscally unsustainable.
title: Аудиопроцессорная обработка сигналов звукового вещания в каналах передачи
Creators: name: ELS IPR BOOKS
Publisher: name: Московский технический университет связи и информатики
Year: 2016

description: В данном учебном пособии рассмотрены основные характеристики сигналов и каналов звукового вещания, базовые процедуры, используемые при обработке звукового вещательного сигнала (ЗВС), основные алгоритмы аудиопроцессорной обработки сигнала в канале передачи. Проведен анализ и оценка возникающих искажений сигнала на всех этапах его передачи, начиная с первичного цифрового преобразования. Особое внимание уделено проблеме объективной оценки качества ЗВС в системах, не нормируемых в рамках современного метрологического обеспечения, что приводит в ряде случаев к неэффективности аудиопроцессорной обработки на всех стадиях передачи по каналу вещания. Подробное рассмотрение алгоритмов обработки, ранее использовавшихся только в тракте формирования программ, связано с тем, что в современном канале такая обработка используется на всех стадиях передачи, в трактах первичного, вторичного распределения и абонентском приемнике. Учебное пособие полезно студентам старших курсов по направлению подготовки 11.03.01 - Радиотехника (уровень бакалавриата), 11.03.02 - Инфокоммуникационные технологии (уровень бакалавриата), 11.04.01 - Радиотехника (уровень магистратуры), 11.04.02 - Инфокоммуникационные технологии и системы связи (уровень магистратуры), специалистам направления 10.05.02, аспирантам направления 11.06.01, а также специалистам эксплуатационных служб радиосвязи, радиовещания и телевидения.
Redox processes in energy-related technologies – use of mixed ionic-electronic conductors for oxygen production
Creators: name: Cichy, Kacper
Publisher: name: AGH University of Science and Technology, Kraków, Poland
Year: 2023

description: This dissertation is focused on the hexagonal rare-earth manganites, RMnO3+δ (R – smaller rare earth elements), a group of mixed ionic-electronic conductors (MIEC), and their potential application in energy-related technologies. Thanks to the Mn-related redox process occurring in RMnO3+δ accompanied by the large changes in oxygen nonstoichiometry δ, these manganites can be considered so-called oxygen storage materials (OSM) and have multiple possible applications. One such application is O2 production via air separation in the process of temperature swing absorption (TSA). The unique feature of RMnO3+δ is the temperature, where redox reactions take place – in the range of 200‑300 °C, exceptionally low, compared to other OSM groups. This work aims to address the following issues:

To develop an RMnO3+δ able to work in air atmosphere in the TSA process.

Find possible correlations between chemical composition and operating parameters of RMnO3+δ to allow designing materials adjusted to a desired working environment.

Asses the competitivity of TSA with conventional O2 production methods.
Metastability in a lattice gas with strong anisotropic interactions under Kawasaki dynamics
Creators: name: Baldassarri, Simone
name: Nardi, Francesca Romana
Publisher: name: arXiv
Year: 2020
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: In this paper we analyze metastability and nucleation in the context of a local version of the Kawasaki dynamics for the two-dimensional strongly anisotropic Ising lattice gas at very low temperature. Let $Λ\subset\mathbb{Z}^2$ be a finite box. Particles perform simple exclusion on $Λ$, but when they occupy neighboring sites they feel a binding energy $-U_1<0$ in the horizontal direction and $-U_2<0$ in the vertical one. Thus the Kawasaki dynamics is conservative inside the volume $Λ$. Along each bond touching the boundary of $Λ$ from the outside to the inside, particles are created with rate $ρ=e^{-Δβ}$, while along each bond from the inside to the outside, particles are annihilated with rate $1$, where $β$ is the inverse temperature and $Δ>0$ is an activity parameter. Thus, the boundary of $Λ$ plays the role of an infinite gas reservoir with density $ρ$. We consider the parameter regime $U_1>2U_2$ also known as the strongly anisotropic regime. We take $Δ\in{(U_1,U_1+U_2)}$ and we prove that the empty (respectively full) configuration is a metastable (respectively stable) configuration. We consider the asymptotic regime corresponding to finite volume in the limit of large inverse temperature $β$. We investigate how the transition from empty to full takes place. In particular, we estimate in probability, expectation and distribution the asymptotic transition time from the metastable configuration to the stable configuration. Moreover, we identify the size of the \emph{critical droplets}, as well as some of their properties. We observe very different behavior in the weakly and strongly anisotropic regimes. We find that the \emph{Wulff shape}, i.e., the shape minimizing the energy of a droplet at fixed volume, is not relevant for the nucleation pattern.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Extensions of the Standard Model (SM) Higgs sectorallow for a rich cosmological history around the electroweak(EW) scale. We show that besides strong firstorder phase transitions, which have thoroughly been studied in the literature in two-Higgs doublet models (2HDM),in the context of the next-to 2HDM (N2HDM)other phenomena like EW symmetry non-restoration or vacuum trappingcan occur in certain regions of theparameter space.Focusing on the type~II N2HDM and taking into accountvarious theoretical and experimental constraints,we demonstrate how these novel finite-temperatureeffects are related and how they can be used to furtherconstrain the parameter space of the model.In particular, we show that the presenceof global EW minimum at zero temperature mightnot be a sufficient requirement for the validityof the vacuum configuration. Moreover, weargue that a calculation of the tunneling probabilityis required to accurately predict the thermalhistory of a parameter point, whereas the appearanceof a critical temperature at which the EW phase becomes the deepest minimum is not sufficientfor a transition to take place.
Combining $T_1$ and $T_2$ estimation with randomized benchmarking and bounding the diamond distance

description: The characterization of errors in a quantum system is a fundamental step for two important goals. First, learning about specific sources of error is essential for optimizing experimental design and error correction methods. Second, verifying that the error is below some threshold value is required to meet the criteria of threshold theorems. We consider the case where errors are dominated by the generalized damping channel (encompassing the common intrinsic processes of amplitude damping and dephasing) but may also contain additional unknown error sources. We demonstrate the robustness of standard $T_1$ and $T_2$ estimation methods and provide expressions for the expected error in these estimates under the additional error sources. We then derive expressions that allow a comparison of the actual and expected results of fine-grained randomized benchmarking experiments based on the damping parameters. Given the results of this comparison, we provide bounds that allow robust estimation of the thresholds for fault-tolerance.

A commuting family of time evolutions are obtained by adapting the K matrices and the double row construction of transfer matrices in solvable lattice models to a crystal setting. Factorized scattering among the left and the right moving solitons and the boundary reflection rule are determined.

X-ray Periodicity in AGN

Year: 2004
Subjects: subject: Astrophysics (astro-ph)

description: Significant (marginal) detections of periodic signals have been recently reported in 3 (4) Active Galactic Nuclei. Three of the detections were obtained from long EUVE light curves of moderate-luminosity Seyfert galaxies; the fourth was discovered in Chandra data from the low-luminosity Seyfert 1 galaxy NGC 4395. When compared with Cyg X-1, I find that the period is related to the luminosity as $P\propto L^{2/3}$ rather than the expected one-to-one relationship. This result might be explained if the QPO is associated with the inner edge of the optically thick accretion disk, and the inner edge radius depends on the source luminosity (or black hole mass). A discussion of uncertainties in the period detection methodology is also discussed.

description: We compute the two-loop $β$-function of scalar and spinorial quantum electrodynamics as well as pure Yang-Mills and quantum chromodynamics using the background field method in a fully quadridimensional setup using Implicit Regularization (IREG). Moreover, a thorough comparison with dimensional approaches such as conventional dimensional regularization (CDR) and dimensional reduction (DRED) is presented. Subtleties related to Lorentz algebra contractions/symmetric integrations inside divergent integrals as well as renormalisation schemes are carefully discussed within IREG where the renormalisation constants are fully defined as basic divergent integrals to arbitrary loop order. Moreover, we confirm the hypothesis that momentum routing invariance in the loops of Feynman diagrams implemented via setting well-defined surface terms to zero deliver non-abelian gauge invariant amplitudes within IREG just as it has been proven for abelian theories.

Indigenous wholistic theory for health : enhancing traditional-based indigenous health services in Vancouver
Creators: name: Marsden, Dawn Marie
Publisher: name: University of British Columbia
Year: 2009

description: How traditional healing can be enhanced in cities, has been the subject of discussion between myself and Indigenous Elders, and between many others, for over 15 years. This project was initiated and completed through the recommendations of Indigenous Elders, through prayer and dreaming, and through increasingly specific factors: 1. Two to four hundred years of unequal relations between colonizing and Indigenous peoples, resulting in 2. Significant and persistent inequalities in the health and educational status of Indigenous peoples, leading to 3. Indigenous calls for more culturally appropriate health services, as reflected in the Royal Commission on Aboriginal Peoples (RCAP), instigating 4. Canadian government strategies for implementing the RCAP recommendations, entitled Gathering Strengths, which prompted a 5. Vancouver/Richmond Health Board review of local Aboriginal health and services, entitled Healing Ways, which led to 6. A Strategic Plan to Develop an Aboriginal Healing Centre in Vancouver, in which traditional healing was emphasized This dissertation affirms and extends prior research, including the National Aboriginal Health Organization document "Traditional Medicine in Contemporary Contexts" by asking how the access and provision of traditional-based health services (traditional healing) can be enhanced, by and for Indigenous peoples in a specific location (Greater Vancouver Regional District; Indigenous pop: 77,500), and by designing, implementing and analyzing this research, using Indigenous wholistic theory, storywork, and talking circle methodologies, protocols, and processes of analysis (prayer, dreaming, reflection, dialogue). Collective storywork, confirms and extends prior research, by providing locally-specific and detailed strategies for societal, institutional and community enhancements, including the establishment of a cohesive governance framework, educational campaigns, establishment of integrated health teams, establishment of a traditional-based Indigenous practitioner's council, establishment of liaison positions, and the establishment of traditional-based Indigenous healing centres. In addition, the research process has resulted in an affirmation and extension of: Indigenous wholistic theory, storywork and talking circle methodologies, Indigenous protocols and processes, a model for Indigenous research entitled a Wampum Research Model, a discussion of the inextricability of health and education, a need to prioritize worldview in the non-medical determinants of health, and Graham Hingangaroa and Linda Tuhiwai Smith's criteria for Indigenous theorizing and Indigenous projects.

description: The problem of finding clusters in complex networks has been extensively studied by mathematicians, computer scientists and, more recently, by physicists. Many of the existing algorithms partition a network into clear clusters, without overlap. We here introduce a method to identify the nodes lying ``between clusters'' and that allows for a general measure of the stability of the clusters. This is done by adding noise over the weights of the edges of the network. Our method can in principle be applied with any clustering algorithm, provided that it works on weighted networks. We present several applications on real-world networks using the Markov Clustering Algorithm (MCL).

description: Isomeric states in $^{128}$In and $^{130}$In have been studied with the JYFLTRAP Penning trap at the IGISOL facility. By employing novel ion manipulation techniques, different states were separated and masses of six beta-decaying states were measured. JYFLTRAP was also used to select the ions of interest for identification at a post-trap decay spectroscopy station. A new beta-decaying high-spin isomer feeding the $15^-$ isomer in $^{128}$Sn has been discovered in $^{128}$In at $1797.6(20)$ keV. Shell-model calculations employing a CD-Bonn potential re-normalized with the perturbative G-matrix approach suggest this new isomer to be a $16^+$ spin-trap isomer. In $^{130}$In, the lowest-lying $(10^-)$ isomeric state at $58.6(82)$ keV was resolved for the first time using the phase-imaging ion cyclotron resonance technique. The energy difference between the $10^-$ and $1^-$ states in $^{130}$In, stemming from parallel/antiparallel coupling of $(π0g_{9/2}^{-1})\otimes(ν0h_{11/2}^{-1})$, has been found to be around 200 keV lower than predicted by the shell model. Precise information on the energies of the excited states determined in this work is crucial for producing new improved effective interactions for the nuclear shell model description of nuclei near $^{132}$Sn.

Our time dependent numerical model includes exact treatment of electron synchrotron emission, inverse-Compton scattering, pair production, and evolution of electromagnetic cascades (initiated by pair production or photo-production of pions). We find that (i) The 1 GeV--10 GeV flux is not sensitive to model parameters and is ~10^{-7} erg cm^-2 s^-1 for z=1 bursts, well within the detection capabilities of GLAST; (ii) The sub-TeV flux depends on the surrounding medium density and on the fraction of thermal energy carried by the magnetic field, epsilon_B: It ranges from ~10^{-7} erg cm^-2 s^-1 in the case of typical ISM density and epsilon_B

description: The Randall-Sundrum scenario, with a 1+3-dimensional brane in a 5-dimensional bulk spacetime, can be generalized in various ways. We consider the case where the Z2-symmetry at the brane is relaxed, and in addition the gravitational action is generalized to include an induced gravity term on the brane. We derive the complete set of equations governing the gravitational dynamics for a general brane and bulk, and identify how the asymmetry and the induced gravity act as effective source terms in the projected field equations on the brane. For a Friedmann brane in an anti de Sitter bulk, the solution of the Friedmann equation is given by the solution of a quartic equation. We find the perturbative solutions for small asymmetry, which has an effect at late times.

description: Using transmission electron microscopy (TEM) we studied CaCu3Ti4O12, an intriguing material that exhibits a huge dielectric response, up to kilohertz frequencies, over a wide range of temperature. Neither in single crystals, nor in polycrystalline samples, including sintered bulk- and thin-films, did we observe the twin domains suggested in the literature. Nevertheless, in the single crystals, we saw a very high density of dislocations with a Burger vector of [110], as well as regions with cation disorder and planar defects with a displacement vector 1/4[110]. In the polycrystalline samples, we observed many grain boundaries with oxygen deficiency, in comparison with the grain interior. The defect-related structural disorders and inhomogeneity, serving as an internal barrier layer capacitance (IBLC) in a semiconducting matrix, might explain the very large dielectric response of the material. Our TEM study of the structure defects in CaCu3Ti4O12 supports a recently proposed morphological model with percolating conducting regions and blocking regions.

The behavior of this diffusion process in the presence of an evolutionarily stable strategy is investigated. Moreover, extinction of dominated strategies and stochastic stability of strict Nash equilibria are studied. The general results are illustrated in connection with a discrete war of attrition. A persistence result for the maximum effort strategy is obtained and an explicit expression for the evolutionarily stable strategy is derived.

description: The relevant integration of wind power into the grid has involved a remarkable impact on power system operation, mainly in terms of security and reliability due to the inherent loss of the rotational inertia as a consequence of such new generation units decoupled from the grid. In these weak scenarios, the contribution of wind turbines to frequency control is considered as a suitable solution to improve system stability. With regard to frequency response analysis and grid stability, most contributions introduce wind control discuss generation tripping for isolated power systems under arbitrary power imbalance conditions. Frequency response is then analyzed for hypothetical imbalances usually ranged between 5% and 20%, and assuming averaged energy schedule scenarios. In this paper, a more realistic framework is proposed to evaluate frequency deviations by including high wind power integration. With this aim, unit commitment schemes and frequency load shedding are considered in this work for frequency response analysis under high wind power penetration. The Gran Canaria Island's isolated power system (Spain) is used for evaluation purposes. Results provide a variety of influences from wind frequency control depending not only on the wind power integration, but also the generation units under operation, the rotational inertia reductions as well as the available reserves from each resource, aspects that have not been addressed previously in the specific literature to evaluate frequency excursions under high wind power integration.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: PSR J1809-1917 is a young ($τ=51$ kyr) energetic ($\dot{E}=1.8\times10^{36}$ erg s$^{-1}$) radio pulsar powering an X-ray pulsar wind nebula (PWN) that exhibits morphological variability. We report on the results of a new monitoring campaign by the Chandra X-ray Observatory (CXO), carried out across 6 epochs with a $\sim$7-week cadence. The compact nebula can be interpreted as a jet-dominated outflow along the pulsar's spin axis. Its variability can be the result of Doppler boosting in the kinked jet whose shape changes with time (akin to the Vela pulsar jet). The deep X-ray image, composed of 405 ks of new and 131 ks of archival CXO data, reveals an arcminute-scale extended nebula (EN) whose axis of symmetry aligns with both the axis of the compact nebula and the direction toward the peak of the nearby TeV source HESS J1809-193. The EN's morphology and extent suggest that the pulsar is likely moving through the ambient medium at a transonic velocity. We also resolved a faint 7$'$-long nonthermal collimated structure protruding from the PWN. It is possibly another instance of a "misaligned outflow" (also known as a "kinetic jet") produced by high-energy particles escaping the PWN's confinement and tracing the interstellar magnetic field lines. Finally, taking advantage of the 536 ks exposure, we analyzed the point sources in the J1809 field and classified them using multiwavelength data. None of the classified sources in the field can reasonably be expected to produce the extended TeV flux in the region, suggesting that PSR J1809-1917 is indeed the counterpart to HESS/eHWC J1809-193.

description: A variety of physical, social and biological systems generate complex fluctuations with correlations across multiple time scales. In physiologic systems, these long-range correlations are altered with disease and aging. Such correlated fluctuations in living systems have been attributed to the interaction of multiple control systems; however, the mechanisms underlying this behavior remain unknown. Here, we show that a number of distinct classes of dynamical behaviors, including correlated fluctuations characterized by $1/f$-scaling of their power spectra, can emerge in networks of simple signaling units. We find that under general conditions, complex dynamics can be generated by systems fulfilling two requirements: i) a ``small-world'' topology and ii) the presence of noise. Our findings support two notable conclusions: first, complex physiologic-like signals can be modeled with a minimal set of components; and second, systems fulfilling conditions (i) and (ii) are robust to some degree of degradation, i.e., they will still be able to generate $1/f$-dynamics.
Benchmarking Blocking Algorithms for Web Entities

description: An increasing number of entities are described by interlinked data rather than documents on the Web. Entity Resolution (ER) aims to identify descriptions of the same real-world entity within one or across knowledge bases in the Web of data. To reduce the required number of pairwise comparisons among descriptions, ER methods typically perform a pre-processing step, called \emph{blocking}, which places similar entity descriptions into blocks and thus only compare descriptions within the same block. We experimentally evaluate several blocking methods proposed for the Web of data using real datasets, whose characteristics significantly impact their effectiveness and efficiency. The proposed experimental evaluation framework allows us to better understand the characteristics of the missed matching entity descriptions and contrast them with ground truth obtained from different kinds of relatedness links.

description: We present an overview of our recent measurements on the crossover from a Bose-Einstein condensate of molecules to a Bardeen-Cooper-Schrieffer superfluid. The experiments are performed on a two-component spin-mixture of $^6$Li atoms, where a Fesh\-bach resonance serves as the experimental key to tune the s-wave scattering length and thus to explore the various interaction regimes. In the BEC-BCS crossover, we have characterized the interaction energy by measuring the size of the trapped gas, we have studied collective excitation modes, and we have observed the pairing gap. Our observations provide strong evidence for superfluidity in the strongly interacting Fermi gas.

description: В природе все, что имеет начало, имеет и конец. В течение жизни объект расходует свои ресурсы и, наконец, погибает. Так же происходит и с надежностью. Создается техническое средство с определенным ресурсом. В процессе эксплуатации оно приносит человеку пользу за счет потери этого ресурса. Оно отказывает (болеет), его ремонтируют (лечат). Этот процесс длится до тех пор, пока эксплуатация технического средства целесообразна. Этот процесс и все, что с ним связано (применительно к техническим средствам), и изучает теория надежности.
Educational change and year-round schooling : the role of transformative leaders
Creators: name: Oberg, Steven Lynn
Publisher: name: University of British Columbia

description: This study examines whether there is a relationship between transformative leadership with its constituent ideas of agency, moral purpose, and power, and the ability to successfully introduce sustainable school change. The central tenet of the conceptual framework is transformative leadership as informed by the literature on year-round schooling and educational change. Through a series of interviews, I examine why and how educational leaders, at school and district levels, continue to promote and introduce school-calendar change (commonly known as year-round schooling) in the face of what are often substantial political and social battles. My respondents came from four jurisdictions in the United States and three in Canada, some in which the reform was mandated and others in which it was voluntarily instituted by school leaders. They came from schools with various calendars—multi, single, and dual-track that had been implemented between 1969 and 1999. The impetus for the reform (whether voluntary or mandated) had little to do with its viability, but the implementation processes and procedures used by the school leader were critical. A calendar change was implemented to accomplish various goals, from accommodating more students in existing buildings to bettering the learning experience of children to achieving equity. Not only were explicit goals realized, many unanticipated outcomes were also found. Findings relate to the three-part conceptual framework. First, participants report that year-round schooling is a viable educational reform with the ability to provide fiscal and educational benefits to the whole school community. It can garner the support of the parents and wider community and make a difference beyond the school itself. Second, successful educational reform requires goal clarity, attention to processes, and an understanding that the forces of tradition (habitus) are powerful but may be overcome. Third, transformative educational leaders may surmount resistance and introduce successful educational change if they understand the interconnections among agency, moral purpose, and power. All three are simultaneously necessary to achieve reform that has the ability to decrease inequities in educational performance and thus to be transformative.

description: We use single-particle tracking to study the elastic properties of single microtubules grafted to a substrate. Thermal fluctuations of the free microtubule's end are recorded, in order to measure position distribution functions from which we calculate the persistence length of microtubules with contour lengths between 2.6 and 48 micrometers. We find the persistence length to vary by more than a factor of 20 over the total range of contour lengths. Our results support the hypothesis that shearing between protofilaments contributes significantly to the mechanics of microtubules.
