description: Using the observed rate of short-duration gamma-ray bursts (GRBs) it is possible to make predictions for the detectable rate of compact binary coalescences in gravitational-wave detectors. These estimates rely crucially on the growing consensus that short gamma-ray bursts are associated with the merger of two neutron stars or a neutron star and a black hole, but otherwise make no assumptions beyond the observed rate of short GRBs. In particular, our results do not assume coincident gravitational wave and electromagnetic observations. We show that the non-detection of mergers in the existing LIGO/Virgo data constrains the progenitor masses and beaming angles of gamma-ray bursts. For future detectors, we find that the first detection of a NS-NS binary coalescence associated with the progenitors of short GRBs is likely to happen within the first 16 months of observation, even in the case of a modest network of observatories (e.g., only LIGO-Hanford and LIGO-Livingston) operating at modest sensitivities (e.g., advanced LIGO design sensitivity, but without signal recycling mirrors), and assuming a conservative distribution of beaming angles (e.g. all GRBs beamed at θ=30 deg). Less conservative assumptions reduce the waiting time until first detection to weeks to months. Alternatively, the compact binary coalescence model of short GRBs can be ruled out if a binary is not seen within the first two years of operation of a LIGO-Hanford, LIGO-Livingston, and Virgo network at advanced design sensitivity. We also demonstrate that the rate of GRB triggered sources is less than the rate of untriggered events if θ<30 deg, independent of the noise curve, network configuration, and observed GRB rate. Thus the first detection in GWs of a binary GRB progenitor is unlikely to be associated with a GRB.

description: Die derzeitige Schuldenkrise in Euroland ist das Ergebnis zweier Entwicklungen: der deutschen Unterbewertungspolitik und der Finanzkrise. Die Unterbewertungspolitik der BRD hat dafür gesorgt, daß sich in den schwächeren Euroländern eine hohe Schuldenlast auftürmte und die Finanzkrise ließ die Risikoaversion an den Finanzmärkten steigen, was zu steigenden Risikoaufschlägen für die Schuldnerländer führte. Damit wurden die Schulden untragbar. Zugleich aber durfte ein Konkurs der Länder nicht zugelassen werden, um eine Kettenreaktion im Bankensystem und damit ein Wiederaufleben der Finanzkrise zu vermeiden. Da Euroland, allen voran die BRD, eine Bankenrettung, die auf eine weitgehende Verstaatlichung des Bankensystems hinausgelaufen wäre, ausschloß, wurde eine Konkursverschleppung betrieben, mit dem Ziel, den Banken die Gelegenheit zu geben, ihre faulen Forderungen auszutauschen. Die Zeche zahlen die Schuldnerländer, allen voran Griechenland, und die Steuerzahler aller Euroländer.

description: Studierende kommen zunächst mit dem einfachen Ausgabenmultiplikator in Kontakt. Zwar führen alle Lehrbücher auch die Erweiterungen ein, was aber im Gedächtnis haften bleibt, ist der einfache Multiplikator, der einen (oft: drastisch) höheren Wert als empirisch gemessene Multiplikatoren aufweist. Dieser Text gibt einen Überblick über empirische Schätzungen und zeigt sodann, dass diese der keynesianischen Theorie keineswegs widersprechen, sondern dass die üblichen Erweiterungen des Multiplikators durchaus auf Werte in der empirisch gemessenen Größenordnung führen. Es wird dann im weiteren herausgearbeitet, dass diese Abschwächungen des Multiplikators aber keineswegs eine Abschwächung der Wirksamkeit des Multiplikatorzusammenhangs bedeuten, sondern dass sich die niedrigeren Werte vielmehr einer (verfälschenden) Partialbetrachtung verdanken: Einkommensabhängige Steuern verstärken in Wahrheit die Wirksamkeit von Fiskalpolitik statt sie abzuschwächen – und der niedrigere Multiplikator der offenen Volkswirtschaft heißt nicht, dass zusätzliche Staatsnachfrage weniger Einkommenswirkungen hat, sondern nur dass diese Wirkungen zum Teil anderswo (nämlich im Ausland) anfallen und daher nicht mitgezählt werden.

description: We study numerically how the structures of distinct networks influence the epidemic dynamics in contact process. We first find that the variability difference between homogeneous and heterogeneous networks is very narrow, although the heterogeneous structures can induce the lighter prevalence. Contrary to non-community networks, strong community structures can cause the secondary outbreak of prevalence and two peaks of variability appeared. Especially in the local community, the extraordinarily large variability in early stage of the outbreak makes the prediction of epidemic spreading hard. Importantly, the bridgeness plays a significant role in the predictability, meaning the further distance of the initial seed to the bridgeness, the less accurate the predictability is. Also, we investigate the effect of different disease reaction mechanisms on variability, and find that the different reaction mechanisms will result in the distinct variabilities at the end of epidemic spreading.

description: Die klassische Lehre stößt beim Versuch, Phänomene wie z.B. die Bildung von Blasen in der Wirtschaft zu erklären, an ihre Grenzen. Während die Effizienzmarkthypothese die Annahme trifft, dass auf Märkten keine Unsicherheit herrscht, da alle Marktteilnehmer sich vollständig rational verhalten und sie über alle Informationen, die für ihre jeweiligen Entscheidungen notwendig sind, verfügen, sah Keynes es als erwiesen an, dass Menschen oftmals aus einen spontanen Antrieb heraus handeln und nicht auf Basis rationaler Erwartungen. In diesem Zusammenhang stellte er dem rationalen Denken des Menschen, die Idee der „Animal Spirits“ gegenüber. Ein Konzept das von Robert J. Shiller und George A. Akerlof aufgegriffen wurde, um u.a. die Volatilität der Märkte zu verstehen.

description: We report the discovery of a bright (V ~ 13.7), extremely low-mass white dwarf in a close double degenerate system. We originally selected GALEX J171708.5+675712 for spectroscopic follow-up among a group of white dwarf candidates in an ultraviolet-optical reduced proper-motion diagram. The new white dwarf has a mass of 0.18 M_solar and is the primary component of a close double degenerate system (P=0.246137 d, K_1 = 288 km/s) comprising a fainter white dwarf secondary with M_2 ~ 0.9 M_solar. Light curves phased with the orbital ephemeris show evidence of relativistic beaming and weaker ellipsoidal variations. The light curves also reveal secondary eclipses (depth ~ 8 mmag) while the primary eclipses appear partially compensated by the secondary gravitational deflection and are below detection limits. Photospheric abundance measurements show a nearly solar composition of Si, Ca, and Fe (0.1-1 solar), while the normal kinematics suggest a relatively recent formation history. Close binary evolutionary scenarios suggest that extremely low mass white dwarfs form via a common-envelope phase and possible Roche-lobe overflow.

description: Romers IS-MP-modell provides a convenient framework that, with a few extensions, allows to compare neoclassical and Keynesian economics within the context of the same model. This might facilitate discussions between proponents of the different paradigms. It turns out that the neoclassical version depends on the assumption of a rather special class of IS curves. The scepticism of Keynesians against the automatic attainment of an equilibrium is thus generally justified, as is the argument in favour of fiscal policy. The paper closes with a short exposition of a monetary Keynesian approach.

Modeling item--item similarities for personalized recommendations on Yahoo! front page

description: We consider the problem of algorithmically recommending items to users on a Yahoo! front page module. Our approach is based on a novel multilevel hierarchical model that we refer to as a User Profile Model with Graphical Lasso (UPG). The UPG provides a personalized recommendation to users by simultaneously incorporating both user covariates and historical user interactions with items in a model based way. In fact, we build a per-item regression model based on a rich set of user covariates and estimate individual user affinity to items by introducing a latent random vector for each user. The vector random effects are assumed to be drawn from a prior with a precision matrix that measures residual partial associations among items. To ensure better estimates of a precision matrix in high-dimensions, the matrix elements are constrained through a Lasso penalty. Our model is fitted through a penalized-quasi likelihood procedure coupled with a scalable EM algorithm. We employ several computational strategies like multi-threading, conjugate gradients and heavily exploit problem structure to scale our computations in the E-step. For the M-step we take recourse to a scalable variant of the Graphical Lasso algorithm for covariance selection. Through extensive experiments on a new data set obtained from Yahoo! front page and a benchmark data set from a movie recommender application, we show that our UPG model significantly improves performance compared to several state-of-the-art methods in the literature, especially those based on a bilinear random effects model (BIRE). In particular, we show that the gains of UPG are significant compared to BIRE when the number of users is large and the number of items to select from is small. For large item sets and relatively small user sets the results of UPG and BIRE are comparable. The UPG leads to faster model building and produces outputs which are interpretable.

Die Aufgabe der Portfoliooptimierung ist es, die optimalen Gewichtungen für die Vermögenswerte zu finden, sodass der Nutzen des Investors größtmöglich ist. In der Theorie und der Praxis ist diese Aufgabe nicht leicht zu lösen, da es auf dem Weg zu einem guten Investment verschiedene Schwierigkeiten zu bewältigen und Unsicherheiten in Kauf zu nehmen gilt. Dazu gehören die Ermittlung der Liquiditätspräferenz, der Risikotragfähigkeit und der Risikotoleranz des Investors, sowie die Bestimmung des Anlagehorizontes und eines geeigneten Investment Opportunity Sets.

description: We investigate shock waves in the unitary Fermi gas by using the zero-temperature equations of superfluid hydrodynamics. We obtain analytical solutions for the dynamics of a localized perturbation of the uniform gas. These supersonic bright and subsonic dark solutions produce, after a transient time, an extremely large (divergent) density gradient: the shock. We calculate the time of formation of the shock and also simulate the space-time behavior of the waves by solving generalized hydrodynamic equations, which include a reliable dispersive regularization of the shock. We find that the shock spreads into wave ripples whose properties crucially depend on the chosen initial configuration.

description: In contrast to Keynes' theory, the rate of interest is not modelled as a price for parting with cash but as a price required by wealth owners for holding (the national) currency. Thus the equilibrium discount rate of the central bank can be seen as determined by market forces. In consequence involuntary unemployment may occur at positive equilibrium rates of interest and is not limited to the zero lower bound.

The initial - boundary problem with Neumann conditions is analyzed. When the source term F is a linear function, then the explicit solution is obtained. When F is non linear, some results on existence, uniqueness and a priori estimates are deduced. As example of physical model the reaction - diffusion system of Fitzhugh Nagumo is considered.

description: This report compares the use of different criteria to distinguish between pedal cyclist hospitalised injury cases occurring in on-road and off-road settings. The Traffic method overestimates on-road cases because a coding rule requires that cases where place of occurrence is unspecified should be coded as occurring ‘in traffic’, while the Place method likely underestimates on-road cases because some cases with unspecified place of occurrence will have occurred on-road. Ways to improve delineation between on-road and off-road cases are proposed.

description: Lithium-ion battery cells not only show different behaviors depending on degradation and charging states, but also overcharge and overdischarge of cells shorten battery life and cause safety problems, thus studies aiming to provide an accurate state of a cell are required. Measurements of battery cell impedance are used for cell SoH and SoC estimation techniques, but it generally takes a long time for a cell in each state to be prepared and cell voltage response is measured when charging and discharging under each condition. This study introduces an electrical equivalent circuit model of lithium-ion cells developed in the MATLAB/Simulink environment. Cell SoC, SoH, temperature, and C-rate are considered for more accurate cell impedance prediction, and the simulation results are verified with the measurement results. The developed model is suitable for use in cell SoC and SoH monitoring studies by successfully outputting cell impedance through real-time prediction of cell voltage during discharge.

description: We theoretically propose and experimentally demonstrate coherent wavelength conversion of optical photons using photon-phonon translation in a cavity-optomechanical system. For an engineered silicon optomechanical crystal nanocavity supporting a 4 GHz localized phonon mode, optical signals in a 1.5 MHz bandwidth are coherently converted over a 11.2 THz frequency span between one cavity mode at wavelength 1460 nm and a second cavity mode at 1545 nm with a 93% internal (2% external) peak efficiency. The thermal and quantum limiting noise involved in the conversion process is also analyzed, and in terms of an equivalent photon number signal level are found to correspond to an internal noise level of only 6 and 4x10-3 quanta, respectively.

description: Solows' growth theory addresses two questions: (a) how does the economy grow in to a stationary state equilibrium and (b) what will happen, if the growth of external factors induces a growth process. Both questions can be addressed in a Keynesian context too – although they are answered rather differently, as here demand and not some factor endowment is the restrictive factor. A model is presented, which integrates the multiplier of the General Theory and the reasoning of the Treatise to obtain a growth theory.

description: In a monetary Keynesian perspective the exchange rate is an asset price. NCO therefore doesn't determine the exchange rate, but net exports determine NCO. Thus the effect of a real devaluation is depicted differently in the IS-MP diagram: A real devaluation shifts IS to the right add thus increases income and employment (while it diminishes the wage share). Only in the longer run may the change in the international investment position exert an influence on the exchange rate. The appendix provides a short overview over German mercantilistic policy in the Naughties.

description: The sunspot number varies roughly periodically with time. However the individual cycle durations and the amplitudes are found to vary in an irregular manner. It is observed that the stronger cycles are having shorter rise times and vice versa. This leads to an important effect know as the Waldmeier effect. Another important feature of the solar cycle irregularity are the grand minima during which the activity level is strongly reduced. We explore whether these solar cycle irregularities can be studied with the help of the flux transport dynamo model of the solar cycle. We show that with a suitable stochastic fluctuations in a regular dynamo model, we are able to reproduce many irregular features of the solar cycle including the Waldmeier effect and the grand minimum. However, we get all these results only if the value of the turbulent diffusivity in the convection zone is reasonably high.

description: We present the online MultiDark Database -- a Virtual Observatory-oriented, relational database for hosting various cosmological simulations. The data is accessible via an SQL (Structured Query Language) query interface, which also allows users to directly pose scientific questions, as shown in a number of examples in this paper. Further examples for the usage of the database are given in its extensive online documentation (www.multidark.org). The database is based on the same technology as the Millennium Database, a fact that will greatly facilitate the usage of both suites of cosmological simulations. The first release of the MultiDark Database hosts two 8.6 billion particle cosmological N-body simulations: the Bolshoi (250/h Mpc simulation box, 1/h kpc resolution) and MultiDark Run1 simulation (MDR1, or BigBolshoi, 1000/h Mpc simulation box, 7/h kpc resolution). The extraction methods for halos/subhalos from the raw simulation data, and how this data is structured in the database are explained in this paper. With the first data release, users get full access to halo/subhalo catalogs, various profiles of the halos at redshifts z=0-15, and raw dark matter data for one time-step of the Bolshoi and four time-steps of the MultiDark simulation. Later releases will also include galaxy mock catalogs and additional merging trees for both simulations as well as new large volume simulations with high resolution. This project is further proof of the viability to store and present complex data using relational database technology. We encourage other simulators to publish their results in a similar manner.

description: There are different economic paradigms with very different views of the functioning of the economic process. I argue that it is important to demonstrate the different foundations of these paradigms in an introductory course. This should be done within the same framework so that it becomes obvious, which differences are due to the perspective of the paradigm and not just to different ways of modelling. In my one semester introduction to economics, I discuss price theory in a simple (one good) production price model while for income and employment the three approaches are compared using the production function which connects the labour market and the goods market of the income expenditure model.

We find the time period and spatial extent over which convection operates is sensitive to the behavior of the nuclear symmetry energy at and above nuclear density. When convection ends within the proto-neutron star, there is a break in the predicted neutrino emission that may be clearly observable.

description: We present XMM-Newton spectra of the Seyfert 2 Galaxy IRAS 00521-7054. A strong feature at ~6 keV (observer's frame) can be formally fitted with a strong (EW=1.3+-0.3 keV in the rest frame) and broad Fe Ka line, extending down to 3 keV. The underlying X-ray continuum could be fitted with an absorbed powerlaw (with Gamma = 1.8+-0.2 and N_H = 5.9 x 10^22 cm^-2) plus a soft component. If due to relativistically smeared reflection by an X-ray illuminated accretion disk, the spin of the supermassive black hole is constrained to be 0.97^+0.03_-0.13 (errors at 90% confidence level for one interesting parameter), and the accretion system is viewed at an inclination angle of 37+-4 degree. This would be the first type 2 AGN reported with strong red Fe Ka wing detected which demands a fast rotating SMBH. The unusually large EW would suggest that the light bending effect is strong in this source. Alternatively, the spectra could be fitted by a dual absorber model (though with a global chi^2 higher by ~ 6 for 283 d.o.f) with N_H1 = 7.0 x 10^22 cm^-2 covering 100% of the X-ray source, and N_H2 = 21.7 x 10^22 cm^-2 covering 71%, which does not require an extra broad Fe Ka line.

description: Cycling efficiency and rate capability of porous copper-coated, amorphous silicon thin-film negative electrodes are compared to equivalent silicon thin-film electrodes in lithium-ion batteries. The presence of a copper layer coated on the active material plays a beneficial role in increasing the cycling efficiency and the rate capability of silicon thin-film electrodes. Between 3C and C/8 discharge rates, the available cell energy decreased by 8% and 18% for 40 nm copper-coated silicon and equivalent silicon thin-film electrodes, respectively. Copper-coated silicon thin-film electrodes also show higher cycling efficiency, resulting in lower capacity fade, than equivalent silicon thin-film electrodes. We believe that copper appears to act as a glue that binds the electrode together and prevents the electronic isolation of silicon particles, thereby decreasing capacity loss. Rate capability decreases significantly at higher copper-coating thicknesses as the silicon active-material is not accessed, suggesting that the thickness and porosity of the copper coating need to be optimized for enhanced capacity retention and rate capability in this system.

description: The temperature induced phase transition is investigated in the one-component scalar field ϕ^4 model on the lattice. Using the GPU cluster a huge amount of Monte Carlo simulation data is collected for a wide interval of coupling values. This gives a possibility to determine the low bound on the coupling constant λ_0 when the transition happens and investigate its type. We found that for the values of λclose to this bound a weak-first-order phase transition takes place. It converts into a second order one with the increase of λ. A comparison with the results obtained in analytic and numeric calculations by other authors is given.

Comprehensive Evaluation and Genetic Testing Confirming Chronic Neutrophilic Leukemia: A Case Report from INDIA
Creators: name: Aijaz, Noor
Publisher: name: Zenodo
Year: 2023

description: Chronic Neutrophilic Leukemia (CNL) is a rare myeloproliferative neoplasm characterized by the proliferation of neutrophilic granulocytes. The most common molecular aberration observed in CNL patients is the somatic activating mutation in colony-stimulating factor 3 receptor gene (CSF3R), with the p.Thr618Ile (p.T618I) mutation being predominant and diagnostically crucial. Here, we report a case of CNL, with co-existence of mutations in CSF3RT618I and ASXL1.

description: Applying a quark combination model for the hadronization of Quark Gluon Plasma (QGP) and A Relativistic Transport (ART) model for the subsequent hadronic rescattering process, we investigate the production of $K^{*0}$ and $Σ^*$ resonances in central Au+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV and 62.4 GeV. The initial $K^{*0}$ produced via hadronization is higher than the experimental data in the low $p_T$ region and is close to the data at 2-3 GeV/c. We take into account the hadronic rescattering effects which lead to a strong suppression of $K^{*0}$ with low $p_T$, and find that the $p_T$ spectrum of $K^{*0}$ can be well described. According to the suppressed magnitude of $K^{*0}$ yield, the time span of hadronic rescattering stage is estimated to be about 13 fm/c at 200 GeV and 5 fm/c at 62.4 GeV. The $p_T$ spectrum of $Σ^*$ directly obtained by quark combination hadronization in central Au+Au collisions at 200 GeV is in well agreement with the experimental data, which shows a weak hadronic rescattering effects. The elliptic flow v2 of $Σ^*$ in minimum bias Au+Au collisions at 200 GeV and $p_T$ spectrum of $Σ^*$ at lower 62.4 GeV are predicted.

description: We obtain time dependent $q$-Gaussian wave-packet solutions to a non linear Schrödinger equation recently advanced by Nobre, Rego-Montero and Tsallis (NRT) [Phys. Rev. Lett. 106 (2011) 10601]. The NRT non-linear equation admits plane wave-like solutions ($q$-plane waves) compatible with the celebrated de Broglie relations connecting wave number and frequency, respectively, with energy and momentum. The NRT equation, inspired in the $q$-generalized thermostatistical formalism, is characterized by a parameter $q$, and in the limit $q \to 1$ reduces to the standard, linear Schrödinger equation. The $q$-Gaussian solutions to the NRT equation investigated here admit as a particular instance the previously known $q$-plane wave solutions. The present work thus extends the range of possible processes yielded by the NRT dynamics that admit an analytical, exact treatment. In the $q \to 1$ limit the $q$-Gaussian solutions correspond to the Gaussian wave packet solutions to the free particle linear Schrödinger equation. In the present work we also show that there are other families of nonlinear Schrödinger-like equations, besides the NRT one, exhibiting a dynamics compatible with the de Broglie relations. Remarkably, however, the existence of time dependent Gaussian-like wave packet solutions is a unique feature of the NRT equation not shared by the aforementioned, more general, families of nonlinear evolution equations.

description: We report the observation of double-quantum coherence signals in a gas of potassium atoms at twice the frequency of the one-quantum coherences. Since a single atom does not have a state at the corresponding energy, this observation must be attributed to a collective resonance involving multiple atoms. These resonances are induced by weak inter-atomic dipole-dipole interactions, which means that the atoms cannot be treated in isolation, even at a low density of $10^{12}$ cm$^{-3}$.

description: While the selection of strongly lensed galaxies with 500μm flux density S_500>100 mJy has proven to be rather straightforward (Negrello et al. 2010), for many applications it is important to analyze samples larger than the ones obtained when confining ourselves to such a bright limit. Moreover, only by probing to fainter flux densities is possible to exploit strong lensing to investigate the bulk of the high-z star-forming galaxy population. We describe HALOS (the Herschel-ATLAS Lensed Objects Selection), a method for efficiently selecting fainter candidate strongly lensed galaxies, reaching a surface density of ~1.5-2 deg^-2, i.e. a factor of about 4 to 6 higher than that at the 100 mJy flux limit. HALOS will allow the selection of up to ~1000 candidate strongly lensed galaxies (with amplifications μ>2) over the full H-ATLAS survey area. Applying HALOS to the H-ATLAS Science Demonstration Phase field (~14.4 deg^2) we find 31 candidate strongly lensed galaxies, whose candidate lenses are identified in the VIKING near-infrared catalog. Using the available information on candidate sources and candidate lenses we tentatively estimate a ~72% purity of the sample. The redshift distribution of the candidate lensed sources is close to that reported for most previous surveys for lensed galaxies, while that of candidate lenses extends to substantially higher redshifts than found in the other surveys. The counts of candidate strongly lensed galaxies are also in good agreement with model predictions (Lapi et al. 2011). Even though a key ingredient of the method is the deep near-infrared VIKING photometry, we show that H-ATLAS data alone allow the selection of a similarly deep sample of candidate strongly lensed galaxies with an efficiency close to 50%; a slightly lower surface density (~1.45 deg^-2) can be reached with a ~70% efficiency.

description: The recent availability of ESO's high-resolution spectrograph CRIRES offers now the opportunity to study numerous spectral features in the near-IR in intermediate-mass main-sequence and pre-main-sequence stars. High-resolution CRIRES spectra were obtained in three spectral regions, two regions around 1mu and one region around 1.57mu containing magnetically sensitive Fe I lines. The largest number of near-IR spectral features was detected and identified in the well-studied magnetic Ap star gamma Equ. Nearly 30% of the spectral lines in the Ap star HD154708, with one of the strongest magnetic fields known among the Ap stars of the order of 25kG, remain unidentified due to a lack of atomic data. Only very few lines belonging to the rare earth element group have been identified in both Ap stars. A number of spectral lines including the Ce III and Dy II lines appear magnetically split due to the presence of a strong magnetic field in their atmospheres. Variable behaviour of lines of the elements He, N, Mg, Si, and Fe over the rotation period in the spectra of HD101412 confirm our previous finding of variability in the optical region. Due to the very fast rotation of 51Oph, only a few spectral lines have been identified with certainty.

description: We construct finite mass, asymptotically flat black hole solutions in d=4 Einstein-Yang-Mills theory augmented with higher order curvature terms of the gauge field. They possess non-Abelian hair in addition to Coulomb electric charge, and, below some non-zero critical temperature, they are thermodynamically preferred over the Reissner-Nordstrom solution. Our results indicate the existence of hairy non-Abelian black holes which are stable under linear, spherically symmetric perturbations.

description: In the paper, we obtain necessary and sufficient conditions for ergodicity (with respect to the normalized Haar measure) of discrete dynamical systems $$ on 2-adic spheres $\mathbf S_{2^{-r}}(a)$ of radius $2^{-r}$, $r\ge 1$, centered at some point $a$ from the ultrametric space of 2-adic integers $\mathbb Z_2$. The map $f\colon\mathbb Z_2\to\mathbb Z_2$ is assumed to be non-expanding and measure-preserving; that is, $f$ satisfies a Lipschitz condition with a constant 1 with respect to the 2-adic metric, and $f$ preserves a natural probability measure on $\mathbb Z_2$, the Haar measure $μ_2$ on $\mathbb Z_2$ which is normalized so that $μ_2(\mathbb Z_2)=1$.

description: Recent experimental breakthroughs have demonstrated that the electron spin in silicon can be reliably injected and detected as well as transferred over distances exceeding 1 mm. We propose an on-chip communication paradigm which is based on modulating spin polarization of a constant current in silicon wires. We provide figures of merit for this scheme by studying spin relaxation and drift-diffusion models in silicon.
