The Missing Memristor: Novel Nanotechnology or rather new Case Study for the Philosophy and Sociology of Science?

description: In 2008, it was widely announced that the missing memristor, a basic two-terminal electrical circuit element, had finally been discovered. The memristor is the fourth and last such circuit element and thus completes circuit theory. Predicted already in 1971, the eventual discovery of something seemingly so basic needed almost 40 years. However, this discovery is doubted. The predicted memristor has no material memory and is based on magnetic flux, but the discovered devices constitute analogue memory storage that do not involve magnetism. The person who originally proposed the memristor did not reject the discovery but instead changed his mind about what a memristor is. We briefly introduce the history and then carefully memristance and the memristor as such. We discuss its status as a model rather than a device. We discuss the discovered devices, their stability, and how stability relates to the consistency of the theoretical entities. A thought experiment assumes a world without magnetism. Inductors cannot exist there, but memory resistors could still be constructed. On the same grounds as the memristor was historically predicted, an "inductor" could then be predicted. Likely, somebody would also 'discover' one. A tentative sociological analysis compares to the flawed detection of gravitational waves but comes to very different conclusions.

OBJECTIVES: The study aimed to understand the impact of integrating a fee waiver for the National Health Insurance Scheme (NHIS) with Ghana's Livelihood Empowerment Against Poverty (LEAP) 1000 cash transfer programme on health insurance enrolment. SETTING: The study was conducted in five districts implementing Ghana's LEAP 1000 programme in Northern and Upper East Regions. PARTICIPANTS: Women, from LEAP households, who were pregnant or had a child under 1 year and who participated in baseline and 24-month surveys (2497) participated in the study. INTERVENTION: LEAP provides bimonthly cash payments combined with a premium waiver for enrolment in NHIS to extremely poor households with orphans and vulnerable children, elderly with no productive capacity and persons with severe disability. LEAP 1000, the focus of the current evaluation, expanded eligibility in 2015 to those households with a pregnant woman or child under the age of 12 months. Over the course of the study, households received 13 payments. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes included current and ever enrolment in NHIS. Secondary outcomes include reasons for not enrolling in NHIS. We conducted a mixed-methods impact evaluation using a quasi-experimental design and estimated intent-to-treat impacts on health insurance enrolment among children and adults. Longitudinal qualitative interviews were conducted with an embedded cohort of 20 women and analysed using systematic thematic coding. RESULTS: Current enrolment increased among the treatment group from 37.4% to 46.6% (n=5523) and decreased among the comparison group from 37.3% to 33.3% (n=4804), resulting in programme impacts of 14 (95% CI 7.8 to 20.5) to 15 (95% CI 10.6 to 18.5) percentage points for current NHIS enrolment. Common reasons for not enrolling were fees and travel. CONCLUSION: While impacts on NHIS enrolment were significant, gaps remain to maximise the potential of integrated programming. NHIS and LEAP could be better streamlined to ensure poor households fully benefit from both services, in a further step towards integrated social protection.

description: In order to maintain efficient tracking in the forward region of H1 after the luminosity upgrade of the HERA machine, the H1 Forward Track Detector was also upgraded. While much of the original software and techniques used for the HERA I phase could be reused, the software for pattern recognition was completely rewritten. This, along with several other improvements in hit finding and high-level track reconstruction, are described in detail together with a summary of the performance of the detector.

The difficulty of discerning what's too tight: Taylor rules and Japanese monetary policy

Year: 2003

description: Observers have relied increasingly on simple reaction functions, such as the Taylor rule, to assess the conduct of monetary policy. Applying this approach to deflationary or near-zero inflation environments is problematic, however, and this paper examines two shortcomings of particular relevance to the Japanese case of the last decade. One is the unusually high degree of uncertainty associated with potential output in an environment of prolonged stagnation and deflation. Consequently, reaction function-based assessments of Japanese monetary policy are so sensitive to the chosen gauge of potential output as to be unreliable. The second shortcoming is the neglect of policy expectations, which become critically important as nominal interest rates approach zero. Using long-term bond yields, we identify five episodes since 1996 characterized by abrupt declines in Japanese inflation expectations. Policies undertaken by the Bank of Japan during this period did little to stabilize expectations, and the August 2000 interest rate increase appears to have intensified deflationary concerns.

Cosmological constant in F(R) supergravity

description: A cosmological constant in the regime of low space-time curvature is calculated in the recently proposed version of F(R) supergravity with a generic cubic function F. The F(R) supergravity is the N=1 supersymmetric extension of f(R) gravity. The cubic model is known to successfully describe a chaotic (slow-roll) inflation in the regime of high space-time curvature. We find that a simple extension of the same model allows a positive cosmological constant in the regime of low space-time curvature. The inflaton superfield in F(R) supergravity (like inflaton in f(R) gravity) violates the Strong Energy Condition and thus breaks the restriction of the standard supergravity (with usual matter) that can only have either a negative or vanishing cosmological constant.

Subjects: Social sciences--Research

description: This paper examines how New Yorkers reshaped the public sphere as they engaged in a series of self-organized, loosely coordinated efforts to collectively make sense of the challenges they faced in responding and recovering from the attack of 9/11. The authors explore how technologies of deliberation, representation, and demonstration were mobilized to widen the scope and diversify the organizational strategies enabling public participation. Drawing on Dewey's philosophy of pragmatism and the social studies of science, they focus on how disparate socio-technologies of assembly offered different affordances that both enabled and inhibited particular discursive practices and forms of collective inquiry.

A study of functional units for information use of scholarly journal articles
Creators: name: Zhang, Lei
Publisher: name: University of British Columbia
Year: 2011

description: This research aims to enhance reading effectiveness and efficiency by presenting the readers with the text in the article that is most relevant to a particular information task, rather than presenting the article in its entirety. It applies the idea of the functional unit, the smallest information unit with a distinct function within four major components of scholarly journal articles — Introduction, Methods, Results and Discussion. First, through a review and analysis of the literature and validation through user surveys, 41 functional units within the four components were identified. Also identified were the relationships between the individual functional units and five information use tasks, and furthermore the relationships among a set of functional units for a particular task. The functional units were classified into three categories (primary, related, additional related) according to how useful they were for each task. Based on this taxonomy, a prototype journal reading system was designed and implemented. Thirty 3rd and 4th year psychology students participated in an experimental study using the prototype system. Content analysis was used to analyze qualitative data collected from retrospective interviews, questionnaire open-ended questions, and screen recordings. A statistical analysis of quantitative data collected via rating scales, logging of time and highlights was also carried out. The answers to comprehension questions were assessed first by content analysis and then by statistical analysis. Participants using the prototype system were significantly more satisfied with the information obtained, highlighted more relevant text, and answered more fully the comprehension questions. The use of functional units was effective in enabling people to focus on specific information and use pieces of relevant information across the article, but not necessarily to move from more relevant to less relevant information. Participants using the prototype system also felt significantly more efficient in obtaining the information. The use of functional units was efficient in enabling people to read less or read selectively. The signaling of functional units seemed to be more effective and efficient for the tasks requiring use of information scattered across articles. This research suggests that information within an article can be organized and presented to benefit readers’ information use.

description: We study D meson resonances in hot, dense quark matter within the NJL model and its Polyakov-loop extension. We show that the mass splitting between D^+ and D^- mesons is moderate, not in excess of 100 MeV. When the decay channel into quasifree quarks opens (Mott effect) at densities above twice saturation density, the decay width reaches rapidly the value of 200 MeV which entails a spectral broadening sufficient to open J/psi dissociation processes. Contrary to results from hadronic mean-field theories, the chiral quark model does not support the scenario of a dropping D meson masses so that scenarios for J/psi dissociation by quark rearrangement built on the lowering of the threshold for this process in a hot and dense medium have to be reconsidered and should account for the spectral broadening.

description: We outline a rigorous method which can be used to solve the many-body Schroedinger equation for a Coulomb interacting electronic system in an external classical magnetic field as well as a quantized electromagnetic field. Effects of the geometry of the electronic system as well as the polarization of the quantized electromagnetic field are explicitly taken into account. We accomplish this by performing repeated truncations of many-body spaces in order to keep the size of the many particle basis on a manageable level. The electron-electron and electron-photon interactions are treated in a nonperturbative manner using "exact numerical diagonalization". Our results demonstrate that including the diamagnetic term in the photon-electron interaction Hamiltonian drastically improves numerical convergence. Additionally, convergence with respect to the number of photon states in the joint photon-electron Fock space basis is fast. However, the convergence with respect to the number of electronic states is slow and is the main bottleneck in calculations.

Micro Incentives and Macro Stability

Economics

description: This essay argues that appropriate assessment of the role of decentralization in China requires careful analysis. First, it is not just that the higher share of local government expenditure in total government expenditure matters, more crucially, higher local fiscal incentives in terms of higher marginal retention rates are important for inducing local governments' support for local business development. Second, however, such high incentives may not be conducive to macroeconomic stability, in particular when local governments have considerable influence over the banking system. Third, the central government's authority in appointing provincial leaders induces a tradeoff between macro stability and development: while it is not so good for local non-state sector development, it plays a role in maintaining macro stability. Therefore, there is a complexity of the relationship between micro incentives and macro stability.
Development Oriented Tax Policy

description: No public policy issue is of more importance that the structure and level of taxes. Tax reform has led governments to fall. Proposals to extend the V.A.T. or increase its rates have been a source of political agitation in Ecuador and Mexico. In many less developed countries, a shortage of funds impedes development efforts, and yet attempts to expand taxation not only meet enormous political resistance, but also often turn out to be futile. Simplistic recommendations to increase the power of the tax police often backfire— generating substantially more revenue for the tax collectors, but not much extra revenue for the public fisc.

Responsible consumption and design for sustainability

Year: 2008

description: Bibliography: p. 137-151
description: Some pages are in colour
description: The goals of the present study were to (a) gam insight into what might be termed a responsible, sustainable material culture by seeking to understand the choices, preferences and perspectives of identified responsible consumers, and (b) to use this information to identify key implications of sustainable consumption for product design. To this end, the researcher initially took part in existing voluntary simplicity group meetings where people met and discussed different aspects of their experiences in relation to responsible consumption and sustainable lifestyles. Second, in-depth semi­directed individual interviews were conducted among people presenting a profile corresponding to the characteristics of sustainable consumption as described in the literature. Third, the researcher engaged in design-centred activities in order to explore and illustrate some issues and findings. Data gathered show that the interviewed responsible consumers are looking for a greater sense of autonomy in relation to the world of objects. Among other things, this unfolds into preferences for products allowing them to be involved in the activity of "doing", and for products that can be easily understood in terms of constitution and functioning. In a context where more people would tend towards sustainable consumption and lifestyle, products would need to be conceived in a way that allowed users to feel a certain amount of control with respect to the products they own and use. The study also underlines that perceived individual benefits, including less stress and more personal time, act as important motivational factors for adopting responsible consumption patterns. In relation to a perceived increase in quality of life, respondents are likely to opt for products or systems allowing them to invest less time, money and care in replacement, maintenance, and repair, in addition to reducing their consumption level. This insight suggests that, to foster responsible consumption among the population in general, individual benefits for responsible consumption could be given greater consideration in the development of more sustainable design solutions and in their positioning. Finally, the research stresses the need for product design to rethink its role and its responsibilities in the production of aesthetic conventions or norms in order to more positively contribute to sustainable development.

description: Diese Studie untersucht Gruppen von Ortsnamen in Deutschland (in den Postleitregionen) nach vorhandenen Ähnlichkeiten. Als Messgröße wird ein Häufigkeitsvektor von Trigrammen in jeder Gruppe herangezogen. Mit der Anwendung des Average Linkage-Algorithmus auf die Messgröße werden Cluster aus räumlich zusammenhängenden Gebieten gebildet, obwohl das Verfahren keine Kenntnis über die Lage der Cluster zueinander besitzt. In den Clustern werden die zehn häufigsten n-Gramme ermittelt, um charakteristische Wortpartikel darzustellen. Die von den Clustern umschriebenen Gebiete lassen sich zwanglos durch historische oder linguistische Entwicklungen erklären. Das hier verwendete Verfahren setzt jedoch kein linguistisches, geographisches oder historisches Wissen voraus, ermöglicht aber die Gruppierung von Namen in eindeutiger Weise unter Berücksichtigung einer Vielzahl von Wortpartikeln in einem Schritt. Die Vorgehensweise ohne Vorwissen unterscheidet diese Studie von den meisten bisher angewendeten Untersuchungen.

description: The localized fermions on the intersection curve $Σ$ of D7-branes, are connected to a N=2 supersymmetric quantum mechanics algebra. Due to this algebra the fields obey a global U(1) symmetry. This symmetry restricts the proton decay operators and the neutrino mass terms. Particularly, we find that several proton decay operators are forbidden and the Majorana mass term is the only one allowed in the theory. A special SUSY QM algebra is studied at the end of the paper. In addition we study the impact of a non-trivial holomorphic metric perturbation on the localized solutions along each matter curve. Moreover, we study the connection of the localized solutions to an N=2 supersymmetric quantum mechanics algebra when background fluxes are turned on.

Capital Market Liberalization and Poverty

Subjects: Managerial economics

description: For capital market liberalization in developing countries, the returns have been difficult to identify: there is no convincing empirical evidence linking open capital markets to economic growth. There is however, considerable evidence of increased risk. Capital market liberalization increases consumption volatility and heightens countries' vulnerability to crises. The poor are least equipped to cope with increased volatility, and they are most affected by financial crises. Capital mobility reduces their bargaining power relative to capital and leads to a decline in the labor share of output. Financial openness delivers the poor few benefits in terms of increased access to credit and other financial services, and it constrains governments' redistributive efforts and anti-poverty fiscal policies. While it is difficult to establish a conclusive direct link between capital market liberalization and increased rates of poverty, the evidence presented in this paper suggests a compelling case that capital market liberalization is bad for the poor in developing countries.

description: Uranium, which is of chemotoxic and radiotoxic, is connately present in coals. In view of its dual roles in resource recovery and environmental impact, the geochemistry of uranium in Chinese coals and its atmospheric emission by coal-fired plants in China are discussed in this article. The average uranium concentration of the majority of Chinese coals is 2.43 mg/kg, which is comparable to that of world coals. However, in coals from certain local regions of China, i.e. Yunnan, Guizhou, Guangxi, Xinjiang, Inner Mongolia, and Chongqing Provinces, the uranium is significantly enriched; and even abnormally enriched to form coal-hosted uranium deposits, e.g. coals from the Yili and Tarim Basins of Xinjiang Province, Bangmai Basin of Yunnan Province, and Mabugang Basin of Guangdong Province. Uranium in Chinese coals is associated with organic matter, silicates, pores, pelitic components, phosphate minerals, and uranium minerals. The enrichment of uranium in Chinese coals is attributed to the weathering of source rocks, volcanic ashes, magmatic intrusion, marine water influence, groundwater, hydrothermal fluids, organic matter, palaeoclimate, and the geologic conditions of coal-accumulating basins. Uranium is prior to partition into fly ash. About 62.9 tons of uranium were released into atmosphere from Chinese coal-fired power plants in 2014. Some environmental and human health problems were historically related to uranium in coal worldwide.
Marginalidad y sujetos no heterosexuales en narrativa y cine de Argentina y Uruguay

description: Bibliography: p. 101-102
description: The main objective of this master's thesis is to study the treatment of non-heterosexual subjects in filmic and literary texts. The central question of this work is to determine if those subjects are represented as marginal or not. The answer to that question is elaborated through the study of four texts: Diego Lerman's film Tan de Repente (Suddenly, 2002), two short stories by Cristina Peri Rossi "El testigo" and "La semana mas maravillosa de nuestras vidas," both part of the anthology Desastres intimos (1997), and finally, Ana Maria Shua's novel La muerte como efecto secundario (Death as a Side Effect, 1997). In each text, the position of the non-heterosexual subject in the narrative structure, in particular the lesbian and travesti, is analyzed on the basis of Gino Germani's research on marginality. This study uses the concept of marginality, which originated in the human sciences, to draw the conclusion that although the texts analyzed carry out a critique of marginalization processes, as ones that seek to silence non­heterosexual subjects, the texts are uneasy in that they fail to represent subjects that, by assuming their sexuality and becoming independent, manage to gain some sort of agency.

description: VODAN Africa has pioneered FAIR-Data Science for clinical patient and science data on COVID prevalence in nine countries in Africa. The concept is based on data visiting of data held in residence, and/or with strict data ownership controls. A return of data benefits to point of care is an explicit part of the model. The technical execution is based on data visiting of distributed data over the internet. The data is produced as both human and machine-readable instances. A proof of concept was realised in September 2020 and a Minimal Viable Product will be tested in September 2021. The approach resolved critical issues of data management in view of GDPR and the need for increased data protection in Africa which has suffered from data extraction, including in relation to health data. The research is a project if the Virus Outbreak data Network (VODAN) - Africa and Asia. It is coordinated by Kampala International University. It received seed funding from the Philips Foundation and support from the Dutch Development Bank, Philips Foundation, Cordaid and the Go-FAIR Foundation.

description: An independent wholesaler with many different upstream suppliers is likely to be better at market coverage than if it were the subsidiary of just one supplier. But where wholesale efforts are focused on resolving externalities (by establishing and administering a directed marketing channel), efforts at expanding market coverage have greater marginal cost and will be commensurately retrenched, so independent wholesaling has a smaller payoff. This suggests that directed marketing channels in Japan known as distribution keiretsu are more likely than others to be headed by a primary wholesaler that is vertically integrated with the manufacturer. We demonstrate the empirical validity of this by showing that foreign direct investment in Japanese wholesaling is heavily concentrated in marketing channels with relatively high incidence of distribution keiretsu. These same marketing channels tend to have a slightly lower rate of import penetration which is indirect evidence that impediments to inward foreign direct investment still existed in Japan in 1997, our year of observation.

description: Dynamical mass measurements hold the key to answering whether ultraluminous X-ray sources (ULXs) are intermediate mass black holes (IMBHs) or stellar mass black holes with special radiation mechanisms. NGC 1313 X-2 is so far the only ULX with HST light curves, the orbital period, and the black hole's radial velocity amplitude based on the He II $\lambda4686$Å disk emission line shift of $\sim200$ km/s. We constrain its black hole mass and other parameters by fitting observations to a binary light curve code with accommodations for X-ray heating of the accretion disk and the secondary. Given the dynamical constraints from the observed light curves and the black hole radial motion and the observed stellar environment age, the only acceptable models are those with 40-50 Myrs old intermediate mass secondaries in their helium core and hydrogen shell burning phase filling 40%-80% of their Roche lobes. The black hole can be a massive black hole of a few tens of $M_\odot$ that can be produced from stellar evolution of low metalicity stars, or an IMBH of a few hundred to above 1000$M_\odot$ if its true radial velocity $2K^\prime<40$ km/s. Further observations are required to better measure the black hole radial motion and the light curves in order to determine whether NGC 1313 X-2 is a stellar black hole or an IMBH.

description: There is empirical evidence that recovery rates tend to go down just when the number of defaults goes up in economic downturns. This has to be taken into account in estimation of the capital against credit risk required by Basel II to cover losses during the adverse economic downturns; the so-called "downturn LGD" requirement. This paper presents estimation of the LGD credit risk model with default and recovery dependent via the latent systematic risk factor using Bayesian inference approach and Markov chain Monte Carlo method. This approach allows joint estimation of all model parameters and latent systematic factor, and all relevant uncertainties. Results using Moody's annual default and recovery rates for corporate bonds for the period 1982-2010 show that the impact of parameter uncertainty on economic capital can be very significant and should be assessed by practitioners.

description: In der betrieblichen Datenverarbeitung ist die Übergabe eines neuen (oder geänderten) Anwendungssystems in den DV-Betrieb eine kritische Situation: Aus Sicht der Fachbereiche und der Anwendungsentwicklung sollte die Anwendung möglichst zügig in Betrieb genommen werden, um Termine einzuhalten und den betrieblichen Nutzen der Anwendung früh auszulösen. Für den DV-Betrieb haben Sicherheit, Stabilität und Kontinuität des laufenden Betriebs höchste Priorität, so dass Anwendungen nur in Betrieb genommen werden, wenn weder die Anwendung noch deren Integration in den Betrieb ein Risiko darstellen. Daher ist der Prozess des Übergangs von der Anwendungsentwicklung in den DV-Betrieb besonders kritisch. Der Artikel berichtet aus einem aktuellen Forschungsprojekt.

Zombie Lending and Depressed Restructuring in Japan

description: In this paper, we propose a bank-based explanation for the decade-long Japanese slowdown following the asset price collapse in the early 1990s. We start with the wellknown observation that most large Japanese banks were only able to comply with capital standards because regulators were lax in their inspections. To facilitate this forbearance the banks often engaged in sham loan restructurings that kept credit flowing to otherwise insolvent borrowers (that we call zombies). Thus, the normal competitive outcome whereby the zombies would shed workers and lose market share was thwarted. Our model highlights the restructuring implications of the zombie problem. The counterpart of the congestion created by the zombies is a reduction of the profits for healthy firms, which discourages their entry and investment. In this context, even solvent banks will not find good lending opportunities. We confirm our story's key predictions that zombiedominated industries exhibit more depressed job creation and destruction, and lower productivity. We present firm-level regressions showing that the increase in zombies depressed the investment and employment growth of non-zombies and widened the productivity gap between zombies and non-zombies.

description: Schon lange müssen Betreiber von IT-Systemen damit rechnen, dass die Systeme angegriffen und in der Folge unbefugt und missbräuchlich genutzt werden. Frühe Fälle sind etwa für das Jahr 1961 verzeichnet, als am MIT das Abrechnungsverfahren des Großrechners durch spezielle Programme unterlaufen wurde und die Programmierer so Rechnerkapazitäten nutzen konnten, ohne die Kosten dafür tragen zu müssen. Derartige Hacker (im Sinne von „Einbrecher“), die damals auch Kontrollen der Telefonsysteme ausschalteten und dadurch unentgeltlich telefonierten, lösten in der Öffentlichkeit durchaus positive Assoziationen aus, da sie als übermächtig wahrgenommene Konzerne und Monopole mit technischem Geschick ausmanövrierten. In Spielfilmen der 70er und 80er Jahre wurden Hacker stilisiert und als Vertreter des Widerstands gegen das Establishment dargestellt. Allerdings sind auch schon seit den 60er Jahren Vermögensschäden durch Manipulationen an IT-Systemen bekannt, mit denen Gehalts- oder Rechnungszahlungen umgeleitet oder Kontostände verändert wurden. Die ersten Schadprogramme, die sich über Übertragungsnetze fortpflanzen und IT-Systeme außer Funktion setzten - so genannte „Würmer“ – werden für das Jahr 1988 notiert. Missbrauch von IT-Systemen ist somit als Begleiterscheinung anzusehen, die nur schwer vermeidbar ist, solange Angreifer zwischen dem erzielbaren Eigennutz und dem notwendigen Aufwand sowie dem Risiko der Entdeckung bzw. Bestrafung abwägen und zum Ergebnis kommen, dass ihr Handeln lohnenswert erscheint. Unter den Begriff "Angriff" (engl.: attacks) fallen alle vorsätzlichen Handlungen mit dem dezidierten Ziel, die IT-Systeme eines Unternehmens zu zerstören, zu schädigen oder zu missbrauchen.

The role of protein tyrosine phosphatase alpha (PTPalpha) in oligodendrocyte development and CNS myelination
Creators: name: Wang, Pei-Shan

description: Oligodendrocytes are specialized cells of the central nervous system (CNS) that are responsible for axonal myelination. They are derived from precursors termed oligodendrocyte progenitor cells (OPCs). In OPCs, the signal transduction pathways that regulate self-renewal versus differentiation remain poorly defined. The tyrosine kinase Fyn plays a critical role in oligodendrocyte differentiation and myelination in the CNS. However, the upstream molecules that regulate Fyn activity in these cells are not well characterized. In these studies, I utilized two model systems, the rat CG4 oligodendroglial cell line and a genetically modified mouse with germline PTPα knock-out, to investigate the role of protein tyrosine phosphatase alpha (PTPα) in OPC differentiation. My results demonstrate that PTPα is required for OPC differentiation and functions in at least two distinct phases during the lifespan and maturation of OPCs. Firstly, upon induction of OPC differentiation, Fyn activation and signaling are significantly reduced in the absence of PTPα, as measured by enhanced negative regulatory phosphorylation of Fyn and reduced activation or inhibition of Fyn downstream effectors such as focal adhesion kinase, Rac1, Cdc42, and Rho. Furthermore, myelination is defective in the brains of PTPα-/- mice, suggesting that OPC maturation requires PTPα-mediated signal transduction cascades. Secondly, OPCs must cease proliferation in order for differentiation to occur, and I found that PTPα-/- cells exhibit enhanced proliferation, as well as decreased cell cycle exit and increased survival. Interestingly, the activities of Ras and the Rho GTPases Rac1, Cdc42, and Rho were significantly increased, and p27 protein levels were significantly decreased, in the absence of PTPα. Moreover, Fyn is responsible for Rho inactivation and p27 accumulation. In conclusion, I propose that PTPα negatively regulates OPC proliferation and promotes cell cycle exit, causing cell fate commitment. Subsequently, PTPα positively regulates and promotes differentiation and maturation. These functions of PTPα in OPC proliferation and differentiation processes are mainly exerted through PTPα-mediated dephosphorylation and activation of Fyn to induce the process-specific regulation of common and distinct Fyn effector molecules.
