description: The Latin alphabet was initially chosen in opposition to Cyrillic: the latter was considered, at the dawn of the Soviet era, a legacy of the Russian imperial culture. Later a considerable change in this perspective took place and Cyrillic was revalued as the alphabet of all the Soviet peoples. For example, Latin writing used for Koryak was replaced in 1938 by Cyrillic and the same happened with languages of Central Asia, a choice more political than cultural, evident also in the changes that took place in post Soviet times. These facts clearly show that the perception of the value of writing systems has changed in contemporary society. Nevertheless, Paleosiberian languages, divided into three groups (plus some isolated languages), have difficulty writing some of their phonemes in Cyrillic, thus demonstrating the change from Latin to Cyrillic was not painless. As a matter of fact, the Cyrillic alphabet does not like diacritics and usually, in its standard version, writes lacking phonemes using a combination of letters: a typical situation in many northern and eastern Caucasian languages. This choice has consequences especially when it is applied to polysyntetic, incorporating and agglutinative languages because the writing is very heavy. In this case a compromise takes place: it involves the use of some Latin letters, the introduction of some special signs, Cyrillic letters with particular values and also the presence of diacritics. A result of all this can be found in transliteration: ISO 9 is still not used for these languages.

description: This study examined therapists’ fidelity to a manualized multi-component cognitive-behavioral intervention for posttraumatic stress disorder (PTSD), including exposure therapy, among public sector patients with a psychotic disorder. Therapists’ competence and adherence was assessed by clinicians at the master’s level or higher who rated 20% of randomly selected audiotaped sessions (n = 57 sessions, coded by two independent raters, with strong interrater agreement). Adherence ratings indicated that therapists complied well with the protocol, and competency ratings typically averaged above “very good” (6 on 7-point Likert scale). Findings suggest that therapists can effectively deliver a manualized cognitive-behavioral intervention for PTSD, with exposure therapy, to patients with severe mental illness without compromise to the structure of sessions and/or to the therapeutic relationship. These data add needed support for the implementation of cognitive-behavioral interventions, including exposure therapy, as effective treatments for PTSD in complicated patient populations such as those with severe forms of mental illness.

description: We provide criteria for the existence of upper frequently hypercyclic subspaces and for common hypercyclic subspaces, which include the following consequences. There exist frequently hypercyclic operators with upper-frequently hypercyclic subspaces and no frequently hypercyclic subspace. On the space of entire functions, each differentiation operator induced by a non-constant polynomial supports an upper frequently hypercyclic subspace, and the family of its non-zero scalar multiples has a common hypercyclic subspace. A question of Costakis and Sambarino on the existence of a common hypercyclic subspace for a certain uncountable family of weighted shift operators is also answered.

Russian (1917-1918) and Armenian (1922) Orthographic Reforms. Assessing the Russian Influence on Modern Armenian Language
Creators: name: Marchesini, Irina
Publisher: name: Studi Slavistici
Year: 2017

description: The Russian Orthographic Reform (1917-1918), which initiated the Armenian one (1922-1924, modified in 1940) has undoubtedly played a central role in the development of Modern Armenian. To support this thesis, the essay retraces the fundamental phases of the reform, focusing on the two decades from the early 1920s to 1940, i.e., the year when the second orthography reform was promulgated. The Armenian case is undoubtedly a very peculiar one amongst the constellation of the linguistic reforms decreed in the Soviet countries outside Russia. In fact, Armenian avoided both Cyrillisation and Latinisation. Nonetheless, the effects of the 1922 orthography reform are still perceived as a heavy burden today. Ultimately, this essay aims at demonstrating that this issue should also be a concern for Russian Studies.

description: Detached eclipsing binaries are a fundamental tool for measuring the physical parameters of stars that are effectively evolving in isolation. Starting from more than 40,000 eclipsing binary candidates identified by the All-Sky Automated Survey for Supernovae (ASAS-SN), we use PHOEBE to determine the sum of the fractional radii, the ratio of effective temperatures, the inclinations, and the eccentricities for 35,464 systems. We visually inspect all the light curve models to verify the model fits and examine the TESS light curves, when available, to select systems with evidence for additional physics, such as spots, mass transfer, and hierarchical triples. We examine the distributions of the eclipsing binary model parameters and the orbital parameters. We identify two groups in the sum of the fractional radii and effective temperature ratio parameter space that may distinguish systems approaching the semidetached limit. Combining Gaia EDR3 with extinction estimates from 3-dimensional dust maps, we examine the properties of the systems as a function of their absolute magnitude and evolutionary state. Finally, we present light curves of selected eclipsing binaries that may be of interest for follow-up studies.

description: Graphene, being an ultrathin, durable, flexible, transparent material with superior conductivity and unusual optical properties, promises many novel applications in electronics, photonics and optoelectronics. For applications in electronics, patterning and modification of electrical properties is very desirable since pristine graphene has no band gap. Here we demonstrate a simple all-optical patterning method for graphene, based on laser induced two-photon oxidation. By tuning the intensity of irradiation and the number of pulses the level of oxidation can be controlled to high precision and, therefore, a band gap can be introduced and electrical and optical properties can be continuously tuned. Arbitrary complex patterning can be performed for air-suspended monolayer graphene or for graphene on substrates. The method works at room temperature in ambient air and no additional processing step is needed. The presented concept allows development of all-graphene electronic and optoelectronic devices and complex circuits with an all-optical method.

description: The present paper features the publication of an unedited manuscript by the Soviet linguist E.D. Polivanov, submitted in November 1927 by its author not for publication but just as a contribution to the discussion around the so-called Abkhaz Analytical Alphabet. This graphic system was devised by the academician Nikolay Yakovlevich Marr on the basis of the Latin alphabet for the representation of all Japhetic (Caucasian) languages. In the first section of the introduction, the main characteristics of Marr’s Analytical Alphabet are presented; the second section addresses the linguistic discussion that followed its introduction in Abkhazia as the official alphabet in 1926 and its replacement two years later by a Latin-based alphabet. The third section comments on some questions of Abkhaz phonetics and transcription; the fourth is devoted to textual and editorial issues. The edition of the Russian text is accompanied by an English translation, prepared by Grazia Giannetta (Macerata).

description: Medicare Part D’s implementation improved access to and affordability of prescription drugs for the elderly without prior drug insurance. Effects for specific drugs and drug classes are less well understood. We assessed Part D’s impact on antipsychotic medication (APM) utilization and out-of-pocket costs among elderly without prior drug insurance. Retail pharmacy claims from 3 nationwide pharmacy chains were used to analyze two time-series designs: 1) a Policy Model, to obtain a policymaker’s perspective: what was the overall impact of Part D on APM use and costs among elderly without drug insurance in 2005 with the opportunity to enroll?, and 2) a Clinical Model, to obtain a clinician’s perspective: what would happen to elderly without drug insurance in 2005 who did enroll in Part D—would they be able to get APMs? At what cost? Subgroup analyses among Part D enrollees evaluated potentially different effects for patients who received a subsidy and patients who used anti-dementia drugs. In the Policy Model, Part D implementation was associated with a 5% increase in APM use and a 37% reduction in out-of-pocket costs, suggesting a modest need for APMs among all previously uninsured elderly. Patients who did enroll in Part D (Clinical Model) had a 97% increase in APM use and a 62% decrease in out-of-pocket costs, suggesting that patients who needed APMs were able to access them at low cost through the Part D program. Part D implementation was associated with increased use and affordability of APMs for elderly without prior drug insurance.

description: The evolution of writing (from ideography to alphabet) is connected with the tendency to denote the smallest segmental units of a language system. The adequacy of graphetics depends on its ability to reproduce all phonemic distinctions. Whereas scientific transcription requires a one-to-one correspondence of phoneme and grapheme, various tools for reduction of grapheme inventory are applied in practical writing systems. This reduction is possible when the phonological structure of a language system is taken into account and the so-called featural elements of script develop, with phonemic traits acquiring unified graphetic expression (generalised elements of the basic symbol, diacritics, digraph series and modification of adjacent letters). Examples of such optimisation can be found both in conscious efforts of professional linguists (transcription adjustment, alphabet development) and in natural evolution of writing systems (cf. “syllable principle of the Russian graphetics”), as well as in projects of amateur enthusiasts with their intuitive methods, which are very successful at times. The article analyses some aspects of alphabet making and rationalisation in the USSR in the 1920s–30s. For example, Rosalija Šor brought into question speakers’ awareness of phonological features; she criticised the universality of Nikolaj Jakovlev’s mathematical formula of the alphabet. On the other hand, the speaker’s linguistic awareness manifested itself in Axmet Baitursynov’s suprasegmental sign for sound harmony in Kazakh, readily accepted by the public at large. There is also discussion of Ivan Tolmačev’s project of the rationalisation of the Russian alphabet presented to the first Soviet People’s Commissar for Education Anatolij Lunačarskij in 1929, discovered recently in the archive of the Russian Academy of Sciences.

Prandtl number effects on the hydrodynamic stability of compressible boundary layers: flow-thermodynamic interactions

Year: 2022
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: Hydrodynamic stability of compressible boundary layers is strongly influenced by Mach number ($M$), Prandtl number ($Pr$) and thermal wall boundary condition. These effects manifest on the flow stability via the flow-thermodynamic interactions. Comprehensive understanding of stability flow physics is of fundamental interest and important for developing predictive tools and closure models for integrated transition-to-turbulence computations. The flow-thermodynamic interactions are examined using linear analysis and direct numerical simulations (DNS) in the following parameter regime: $0.5 \leq M \leq 8$; and, $0.5 \leq Pr \leq 1.3$. For adiabatic wall boundary condition, increasing Prandtl number has a destabilizing effect. In this work, we characterize the behavior of production, pressure-strain correlation and pressure-dilatation as functions of Mach and Prandtl numbers. First and second instability modes exhibit similar stability trends but the underlying flow physics is shown to be diametrically opposite. The Prandtl-number influence on instability is explicated in terms of the base flow profile with respect to the different perturbation mode shapes.
Effective medium theory for anisotropic metamaterials

Subjects: subject: Optics (physics.optics)

description: We present an effective medium theory that can predict the effective permittivity and permeability of a geometrically anisotropic two-dimensional metamaterial composed with a rectangular array of elliptical cylinders. It is possible to obtain a closed-form analytical solution for the anisotropic effective medium parameters if the aspect ratio of the lattice and the eccentricity of elliptical cylinder satisfy certain conditions. The derived effective medium theory can recover the well-known Maxwell-Garnett results in the quasi-static regime. More importantly, it is valid beyond the long-wavelength limit, where the wavelength in the host medium is comparable to the size of the lattice so that previous anisotropic effective medium theories fail. The validity of the derived effective medium theory is verified by band structure calculations. A real sample of a recent theoretically proposed anisotropic medium with near-zero index to control flux is achieved from the derived effective medium theory and control of electromagnetic waves in the sample is clearly demonstrated. The accuracy of the theory is further systematically studied as material and geometric parameter varies, and we find the derived effective medium theory applies over a large range in the parameter space. Such applicability greatly broadens the applicable realm of the effective medium theory and opens many vistas in the design of structures with desired anisotropic material characteristics.

title: Rapid prototyping by laser surface cladding
Creators: name: L. Murphy, M.
Publisher: name: University of Liverpool Repository
Year: 2023

description: In recent years rapid prototyping technology has been implemented in many spheres of industry, particularly the field of product development. Existing process provide the capability to rapidly produce a tangible solid part, directly from three dimensional CAD data, from a range of nonmetallic materials. In many situations the desired end product of a development cycle is a metallic object, whether a component or a tool. The development of a system capable of the direct manufacture of fully dense, metal parts is therefore seen as an important landmark in the evolution of rapid prototyping technology. A unique experimental project has been carried out to investigate the potential of laser surface cladding by pneumatic powder delivery to form the basis for such a process. A layered manufacturing part building strategy is proposed, in which laser cladding is used to deposit the near net shape of each layer. Conventional machining techniques are then used to trim each layer to the exact dimensions specified by the CAD data. A multi-kilowatt carbon dioxide laser was integrated with a four axis machine tool to create an opto-mechanical workstation on which to perform the process. A detailed study of the effects of cladding process parameters on the geometry of the deposited metal was carried out and quantitative relationships derived. These relationships are used to select process parameters appropriate to the geometry of the deposition required. A numerical method to fully describe the deposited clad geometry was developed in order that efficient cutter paths could be generated for the back machining cycle. These relationships are also used to determine the minimum size of deposited bead from which the required layer section may be machined, in order to optimise process efficiency. The application of the technique to the generation of a variety of simple geometries was investigated and the potential problems identified. A preliminary investigation into the process accuracy is made, relating specifically to the predictability of the geometry of multiple layer depositions and the distortion of parts as subsequent layers are deposited. The limits of geometrical complexity possible with the current apparatus, and the unsatisfactory build times involved, suggest that the most attractive application of this technique is as part of a hybrid process, adding a novel additive dimension to existing automated fabrication techniques.

description: Are the diacritical signs of Esperanto contrary to the interests and aspirations of the proletariat? In the early 1920s, Soviet supporters of Ido and Esperanto, two artificial languages with an international vocation, competed for a time about this kind of question. In.this article, we intend to analyse the ideas of the linguist Nikolaj Vladimirovič Jušmanov, expressed in articles written in Russian, but also in Ido and Etem, an artificial language developed by Jušmanov himself. We will see that his ideas about the alphabets (which he believes must be precise, organised and rational) fit into the particular context of the USSR in the 1920s when intentions were to erase the past and create new forms.

description: Nonequilibrium quantum dynamics can give rise to the emergence of novel steady states. We propose a scheme for driving an initially uncorrelated thermal state to generate customized correlation functions by determining and reverse engineering the steady-state two-point functions for a class of Markov processes. We also extend the formalism to the calculation of four-point functions. We then apply our method to generating power-law correlated fermionic Green's functions. Furthermore, we find that the power-law patterns emerge at much shorter times than the convergence to the steady state, at which point the disorder in the two-point correlations disappears. On the other hand, the density-density correlations exhibit steady-state disorder while following a power-law trendline. These ideal steady states appear as intermediate-time quasi-steady states in the presence of perturbations.

description: The famous Itô-Stratonovich dilemma arises when one examines a dynamical system with a multiplicative white noise. In physics literature, this dilemma is often resolved in favour of the Stratonovich prescription because of its two characteristic properties valid for systems driven by Brownian motion: (i) it allows physicists to treat stochastic integrals in the same way as conventional integrals, and (ii) it appears naturally as a result of a small correlation time limit procedure. On the other hand, the Marcus prescription [IEEE Trans. Inform. Theory 24, 164 (1978); Stochastics 4, 223 (1981)] should be used to retain (i) and (ii) for systems driven by a Poisson process, Lévy flights or more general jump processes. In present communication we present an in-depth comparison of the Itô, Stratonovich, and Marcus equations for systems with multiplicative jump noise. By the examples of areal-valued linear system and a complex oscillator with noisy frequency (the Kubo-Anderson oscillator) we compare solutions obtained with the three prescriptions.

description: Objective:To evaluate the effects of diabetic ketoacidosis (DKA) on neurocognitive functions in children and adolescents presenting with new-onset type 1 diabetes.Methods:Newly diagnosed patients were divided into two groups: those with DKA and those without DKA (non-DKA). Following metabolic stabilization, the patients took a mini-mental status exam prior to undergoing a baseline battery of cognitive tests that evaluated visual and verbal cognitive tasks. Follow-up testing was performed 8-12 weeks after diagnosis. Patients completed an IQ test at follow-up.Results:There was no statistical difference between the DKA and non-DKA groups neither in alertness at baseline testing nor in an IQ test at follow-up. The DKA group had significantly lower baseline scores than the non-DKA group for the visual cognitive tasks of design recognition, design memory and the composite visual memory index (VMI). At follow-up, Design Recognition remained statistically lower in the DKA group, but the design memory and the VMI tasks returned to statistical parity between the two groups. No significant differences were found in verbal cognitive tasks at baseline or follow-up between the two groups. Direct correlations were present for the admission CO2 and the visual cognitive tasks of VMI, design memory and design recognition. Direct correlations were also present for admission pH and VMI, design memory and picture memory.Conclusion:Pediatric patients presenting with newly diagnosed type 1 diabetes and severe but uncomplicated DKA showed a definite trend for lower cognitive functioning when compared to the age-matched patients without DKA.

description: The Cyrillic alphabet as a whole and some individual characters belonging to that alphabet in particular have always been associated in the conservative Orthodox mind with tradition, faith, patriotism and a glorified past. While reformers declared that they looked at the alphabet from the point of view of its functionality, traditionalists endowed its letters with various ideological, cultural and aesthetic values. This article considers the following evaluative approaches to the Cyrillic letters: 1. The mystical iconicity of some Cyrillic letters based on the shape of the characters. 2. Various arguments in defence of the letters excluded from the Russian alphabet in 1918. 3. The mythologisation of these arguments (The Old Believers’ spiritual verse of the 1990s). The main purpose of the article is to show the ways in which the ideology is hidden or openly reflected in all the arguments, including those that are purely technical or aesthetic.

Molecular gas dynamics around nuclei of galaxies

description: Recent molecular line observations with ALMA in several nearby Seyferts have revealed the existence of molecular tori, and the nature of gas flows at 10-20~pc scale. At 100~pc scale, or kpc-scale, previous NOEMA work on gravitational torques had shown that only about one third of Seyfert galaxies experienced molecular inflow and central fueling, while in most cases the gas was stalled in rings. At higher resolution, i.e. 10-20~pc scale, it is possible now to see in some cases AGN fueling due to nuclear trailing spirals, influenced by the black hole potential. This brings smoking gun evidence for nuclear fueling. In our sample galaxies, the angular resolution of up to 60~mas allows us to reach the black hole (BH) sphere of influence and the BH mass can be derived more directly than with the M-sigma relation.

subject: FOS: Physical sciences

description: Specific features of two-dimensional nematodynamics give rise to shortfalls of the tensor representation of the nematic order parameter commonly used in computations, especially in theory of active matter. The alternative representation in terms of the vector order parameter follows with small adjustments the classical director-based theory, but is applicable to 2D problems where both nematic alignment and deviation from the isotropic state are variable. Stability analysis of nematic alignment and flow is used as a testing ground. A director-based analysis demonstrates a shortfall of the standard theory, which does not ensure relaxation to equilibrium in a passive system. It also demonstrates the inadequacy of the director-based description, which misses a stabilizing effect of perturbations of the modulus ensuring stability of a passive system on scales far exceeding the healing length.

description: In this work, we study the exclusive decay of $Υ$ into $J/ψ$ in association with $η_c$ ($χ_{c0,1,2}$). The decay widths for different helicity configurations are evaluated up to QCD next-to-leading order within the nonrelativistic QCD framework. We find that the QCD corrections notably mitigate the renormalization scale dependence of the decay widths for all the processes. The branching fraction of $Υ\rightarrow J/ψ+χ_{c1}$ is obtained as $3.73^{+5.10+0.10}_{-2.06-1.19}\times 10^{-6}$, which agrees well with the Belle measurement, i.e., ${\rm Br}(Υ\rightarrow J/ψ+χ_{c1})=(3.90\pm1.21\pm0.23)\times10^{-6}$. For the other processes, our results of the branching fractions are compatible with the upper limits given by the Belle experiments, except for $Υ(2S)\to J/ψ+χ_{c1}$, where some tension exists between theory and experiment. Having the polarized decay widths, we study the $J/ψ$ polarization, which turn out to be independent of any nonperturbative parameters. Further, according to our calculation, it is promising to measure all the processes at Super B factory thanks to the high luminosity.

description: We consider how membrane fluctuations can modify the miscibility of lipid mixtures, that is to say how the phase diagram of a boundary-constrained membrane is modified when the membrane is allowed to fluctuate freely in the case of zero surface tension. In order for fluctuations to have an effect, the different lipid types must have differing Gaussian rigidities. We show, somewhat paradoxically, that fluctuation-induced interactions can be treated approximately in a mean-field type theory. Our calculations predict that, depending on the difference in bending and Gaussian rigidity of the lipids, membrane fluctuations can either favor or disfavor mixing.

description: The adoption of foreign lexical material with preservation of the original written in the Latin alphabet has been a common character for many modern Russian texts since the early 1990s. We observe it particularly in foreign-language brand and product names (pragmatonyms) that are generally written either in the Latin alphabet or transcribed into Cyrillic, not only in advertising but also in many other text types. This applies also to Russian literature, mainly popular fiction, where the occurrence of commercial names has significantly increased in the first decade of the millennium. The number of mentioned brands and commercial products exceeds in the works of some authors 80 whereas the portion of foreign, usually internationally known, brands is larger than of those that are known only in the domestic market. This paper shows the principles of use of Cyrillic and Latin scripting for commercial names in Russian fiction literature of the 21st century. Stylistic, morphological, pragmatic, as well as social pragmatic factors and their interrelation are analysed to decide whether it is Latin or Cyrillic scripting that the author chooses for presentation of a foreign-language commercial name.

Year: 2007

description: Based on a review of literature and consensus, the Portable Monitoring Task Force of the American Academy of Sleep Medicine (AASM) makes the following recommendations: unattended portable monitoring (PM) for the diagnosis of obstructive sleep apnea (OSA) should be performed only in conjunction with a comprehensive sleep evaluation. Clinical sleep evaluations using PM must be supervised by a practitioner with board certification in sleep medicine or an individual who fulfills the eligibility criteria for the sleep medicine certification examination. PM may be used as an alternative to polysomnography (PSG) for the diagnosis of OSA in patients with a high pretest probability of moderate to severe OSA. PM is not appropriate for the diagnosis of OSA in patients with significant comorbid medical conditions that may degrade the accuracy of PM. PM is not appropriate for the diagnostic evaluation of patients suspected of having comorbid sleep disorders. PM is not appropriate for general screening of asymptomatic populations. PM may be indicated for the diagnosis of OSA in patients for whom in-laboratory PSG is not possible by virtue of immobility, safety, or critical illness. PM may also be indicated to monitor the response to non-CPAP treatments for sleep apnea.

description: We give an overview and describe the rationale, methods, and testing of the Hubble Space Telescope (HST) Archival Legacy project "SKYSURF." SKYSURF uses HST's unique capability as an absolute photometer to measure the ~0.2-1.7 $μ$m sky surface brightness (SB) from 249,861 WFPC2, ACS, and WFC3 exposures in ~1400 independent HST fields. SKYSURF's panchromatic dataset is designed to constrain the discrete and diffuse UV to near-IR sky components: Zodiacal Light (ZL; inner Solar System), Kuiper Belt Objects (KBOs; outer Solar System), Diffuse Galactic Light (DGL), and the discrete plus diffuse Extragalactic Background Light (EBL). We outline SKYSURF's methods to: (1) measure sky-SB levels between its detected objects; (2) measure the integrated discrete EBL, most of which comes from AB$\simeq$17-22 mag galaxies; and (3) estimate how much diffuse light may exist in addition to the extrapolated discrete galaxy counts. Simulations of HST WFC3/IR images with known sky-values and gradients, realistic cosmic ray (CR) distributions, and star plus galaxy counts were processed with nine different algorithms to measure the "Lowest Estimated Sky-SB" (LES) in each image between the discrete objects. The best algorithms recover the inserted LES values within 0.2% when there are no image gradients, and within 0.2-0.4% when there are 5-10% gradients. SKYSURF requires non-standard re-processing of these HST images that includes restoring the lowest sky-level from each visit into each drizzled image. We provide a proof of concept of our methods from the WFC3/IR F125W images, where any residual diffuse light that HST sees in excess of the Kelsall et al. (1998) Zodiacal model prediction does not depend on the total object flux that each image contains. This enables us to present our first SKYSURF results on diffuse light in Carleton et al. (2022).

description: In the large-scale, Dark Energy Spectroscopic Instrument (DESI), thousands of fiber positioners will be used. Those are robotic positioners, with two axis, and having the size of a pen. They are tightly packed on the focal plane of the telescope. Dedicated micro-robots have been developed and they use 4mm brushless DC motors. To simplify the implementation and reduce the space occupancy, each actuator will integrate its own electronic control board. This board will be used to communicate with the central trajectory generator, manage low level control tasks and motor current feeding. In this context, we present a solution for a highly compact electronic. This electronic is composed of two layers. The first is the power stage that can drive simultaneously two brushless motors. The second one consists of a fast microcontroller and deals with different control tasks: communication, acquisition of the hall sensor signals, commutation of the motors phases, and performing position and current regulation. A set of diagnostic functions are also implemented to detect failure in the motors or the sensors, and to sense abnormal load change that may be the result of two robots colliding.

Multivariable quantum signal processing (M-QSP): prophecies of the two-headed oracle
Creators: name: Rossi, Zane M.

Publisher: name: arXiv
Year: 2022

description: Recent work shows that quantum signal processing (QSP) and its multi-qubit lifted version, quantum singular value transformation (QSVT), unify and improve the presentation of most quantum algorithms. QSP/QSVT characterize the ability, by alternating ansätze, to obliviously transform the singular values of subsystems of unitary matrices by polynomial functions; these algorithms are numerically stable and analytically well-understood. That said, QSP/QSVT require consistent access to a single oracle, saying nothing about computing joint properties of two or more oracles; these can be far cheaper to determine given an ability to pit oracles against one another coherently. This work introduces a corresponding theory of QSP over multiple variables: M-QSP. Surprisingly, despite the non-existence of the fundamental theorem of algebra for multivariable polynomials, there exist necessary and sufficient conditions under which a desired stable multivariable polynomial transformation is possible. Moreover, the classical subroutines used by QSP protocols survive in the multivariable setting for non-obvious reasons, and remain numerically stable and efficient. Up to a well-defined conjecture, we give proof that the family of achievable multivariable transforms is as loosely constrained as could be expected. The unique ability of M-QSP to obliviously approximate joint functions of multiple variables coherently leads to novel speedups incommensurate with those of other quantum algorithms, and provides a bridge from quantum algorithms to algebraic geometry.

description: Motivated by quantum gravity, semi-classical theory, and quantum theory on curved spacetimes, we study the system of an oscillator coupled to two spin-1/2 particles. This model provides a prototype for comparing three types of dynamics: the full quantum theory, the classical oscillator with spin backreaction, and spins propagating on a fixed oscillator background. From nonperturbative calculations of oscillator and entanglement entropy dynamics, we find that entangled tripartite states produce novel oscillator trajectories, and that the three systems give equivalent dynamics for sufficiently weak oscillator-spin couplings, but deviate significantly for intermediate couplings. These results suggest that semiclassical dynamics with back reaction does not provide a suitable intermediate regime between quantum gravity and quantum theory on curved spacetime.

description: This paper summarizes the results of the first three examinations (2007, 2009, and 2011) of the Sleep Medicine Certification Examination, administered by its six sponsoring American Board of Medical Specialty Boards. There were 2,913 candidates who took the 2011 examination through one of three pathways—self-attested practice experience, previous certification by the American Board of Sleep Medicine, or formal Sleep Medicine fellowship training. The 2011 exam was the last administration in which candidates who had not previously been admitted could take it without completion of formal Sleep Medicine fellowship training. As expected, the number of candidates admitted to the 2011 examination through the practice experience pathway increased, and the overall scores of these candidates were on average lower than the other candidates. Consequently, the pass rate for all first takers of the 2011 examination (65%) was lower than that observed from the 2009 examination (78%) and the 2007 examination (73%). For each administration, candidates admitted through the fellowship training pathway scored the highest; over 90% of them passed the 2011 and 2009 examinations.

At the end of a project, the question of where to put the research data always arises. Once the decision has been made to publish the research data, further questions usually arise that are closely related to data publication. Examples would be: Do I publish the data in a journal or a repository? Do I want to restrict the reuse of my data? What license do I choose?
The Coffee Lecture aims to provide you with helpful knowledge and tips on how to answer exactly these questions.
