Magnetoresistance of doped silicon

We have performed longitudinal magnetoresistance measurements on heavily n-doped silicon for donor concentrations exceeding the critical value for the metal-non-metal transition. The results are compared to those from a many-body theory where the donor-electrons are assumed to reside at the bottom of the many-valley conduction band of the host. Good qualitative agreement between theory and experiment is obtained.Comment: 7 pages, 8 figure

Untying the Mother Tongue

Untying the Mother Tongue explores what it might mean today to speak of someone's attachment to a particular, primary language. Traditional conceptions of mother tongue are often seen as an expression of the ideology of a European nation-state. Yet, current celebrations of multilingualism reflect the recent demands of global capitalism, raising other challenges. The contributions from international scholars on literature, philosophy, and culture, analyze and problematize the concept of ‘mother tongue’, rethinking affective and cognitive attachments to language while deconstructing its metaphysical, capitalist, and colonialist presuppositions.Introduction | ANTONIO CASTORE AND FEDERICO DAL BO | 1-9But You Don’t Get Used to Anything: Derrida on the Preciousness of the Singular | DEBORAH ACHTENBERG | 11-24Philosophy’s Mother Envy: Has There Yet Been a Deconstruction of the Mother Tongue? | MICHAEL ENG | 25-43‘My Mother Tongue Is a Foreign Language’: On Edmond Jabès’s Writing in Exile | FEDERICO DAL BO | 45-83The Mother Tongue at School | JAKOB NORBERG | 85-103Scarspeak: Thinking the Mother Tongue as a Formative Mark | JULIANE PRADE-WEISS | 105-126The Shuffling of Feet on the Pavement: Virginia Woolf on Un-Learning the Mother Tongue | TERESA PRUDENTE | 127-153‘I know you can cant’: Slips of the Mother Tongue in Fred Moten’s B Jenkins | JEFFREY CHAMPLIN | 155-163The Mother Tongue of Love and Loss: Albert Cohen’s Le Livre de ma mère | CAROLINE SAUTER | 165-179The Staircase Wit: or, The Poetic Idiomaticity of Herta Müller’s Prose | ANTONIO CASTORE | 181-210Wandering Words: Translation against the Myth of Origin in Fritz Mauthner’s Philosophy | LIBERA PISANO | 211-227ReferencesNotes on the ContributorsIndexUntying the Mother Tongue, ed. by Antonio Castore and Federico Dal Bo, Cultural Inquiry, 26 (Berlin: ICI Berlin Press, 2023) <https://doi.org/10.37050/ci-26

An Empirical Air-to-Ground Channel Model Based on Passive Measurements in LTE

In this paper, a recently conducted measurement campaign for unmanned-aerial-vehicle (UAV) channels is introduced. The downlink signals of an in-service long-time-evolution (LTE) network which is deployed in a suburban scenario were acquired. Five horizontal and five vertical flight routes were considered. The channel impulse responses (CIRs) are extracted from the received data by exploiting the cell specific signals (CRSs). Based on the CIRs, the parameters of multipath components (MPCs) are estimated by using a high-resolution algorithm derived according to the space-alternating generalized expectation-maximization (SAGE) principle. Based on the SAGE results, channel characteristics including the path loss, shadow fading, fast fading, delay spread and Doppler frequency spread are thoroughly investigated for different heights and horizontal distances, which constitute a stochastic model.Comment: 15 pages, submitted version to IEEE Transactions on Vehicular Technology.
