description: We introduce a method to measure many-body magic in quantum systems based on a statistical exploration of Pauli strings via Markov chains. We demonstrate that sampling such Pauli-Markov chains gives ample flexibility in terms of partitions where to sample from: in particular, it enables to efficiently extract the magic contained in the correlations between widely-separated subsystems, which characterizes the nonlocality of magic. Our method can be implemented in a variety of situations. We describe an efficient sampling procedure using Tree Tensor Networks, that exploits their hierarchical structure leading to a modest $O(\log N)$ computational scaling with system size. To showcase the applicability and efficiency of our method, we demonstrate the importance of magic in many-body systems via the following discoveries: (a) for one dimensional systems, we show that long-range magic displays strong signatures of conformal quantum criticality (Ising, Potts, and Gaussian), overcoming the limitations of full state magic; (b) in two-dimensional $\mathbb{Z}_2$ lattice gauge theories, we provide conclusive evidence that magic is able to identify the confinement-deconfinement transition, and displays critical scaling behavior even at relatively modest volumes. Finally, we discuss an experimental implementation of the method, which only relies on measurements of Pauli observables.

Hamiltonian closures for two-moment fluid models derived from drift-kinetic equations

description: We derive the conditions under which the fluid models obtained from the first two moments of Hamiltonian drift-kinetic systems of interest to plasma physics, preserve a Hamiltonian structure. The adopted procedure consists of determining closure relations that allow to truncate the Poisson bracket of the drift-kinetic system, expressed in terms of the moments, in such a way that the resulting operation is a Poisson bracket for functionals of the first two fluid moments. The analysis is carried out for a class of full drift-kinetic equations and also for drift-kinetic systems in which a splitting between an equilibrium distribution function and a perturbation is performed. In the former case we obtain that the only closure, not involving integral or differential operators, that leads to a Poisson bracket, corresponds to that of an ideal adiabatic gas made of molecules possessing one degree of freedom. In the latter case, Hamiltonian closures turn out to be those in which the second moment is a linear combination of the first two moments, which can be seen as a linearization of the Hamiltonian closure of the full drift-kinetic case. A number of weakly-3D Hamiltonian reduced fluid models of interest, for instance for tokamak plasmas, can be derived in this way and, viceversa given a fluid model with a Hamiltonian structure of a certain type, a parent Hamiltonian drift-kinetic model can then be identified. We make use of this correspondence to identify the drift-kinetic models from which Hamiltonian fluid models for magnetic reconnection and compressible plasma dynamics in the presence of a static but inhomogeneous magnetic field can be derived. The Casimir invariants of the Poisson brackets of the derived fluid models are also discussed.

description: This paper explores the use of semantic knowledge inherent in the cyber-physical system (CPS) under study in order to minimize the use of explicit communication, which refers to the use of physical radio resources to transmit potentially informative data. It is assumed that the acquired data have a function in the system, usually related to its state estimation, which may trigger control actions. We propose that a semantic-functional approach can leverage the semantic-enabled implicit communication while guaranteeing that the system maintains functionality under the required performance. We illustrate the potential of this proposal through simulations of a swarm of drones jointly performing remote sensing in a given area. Our numerical results demonstrate that the proposed method offers the best design option regarding the ability to accomplish a previously established task -- remote sensing in the addressed case -- while minimising the use of radio resources by controlling the trade-offs that jointly determine the CPS performance and its effectiveness in the use of resources. In this sense, we establish a fundamental relationship between energy, communication, and functionality considering a given end application.

description: Mit der Publikation „Kultur- und Kreativwirtschaft in Deutschland – Bestandsaufnahme und Perspektiven!“ leistet die Kreative Deutschland einen Beitrag zur Standortbestimmung einer der Zukunftsbranchen in Deutschland. Vor wenigen Jahren noch als neues, hippes Thema auf der Agenda von Verwaltung und Politik, ist der Diskurs gereift. Es wurde deutlich, dass nach dem Hype der Anfangsjahre, die Kultur- und Kreativwirtschaft nicht einfach wieder verschwindet. Denn die Akteure, Potenziale und Herausforderungen sind nach hunderten von Publikationen und tausenden Veranstaltungen immer noch da. Sie wurden nicht, wie so viele andere Themen, vom nächsten Hype abgelöst. Nun, wo die Karawane der Berater, Think-Tanks, Zukunftsforscher und Consultants sich den „Next Big Things“ widmet, ist es an der Zeit, sich den eigentlichen Themen im Feld der Kultur- und Kreativwirtschaft zuzuwenden. Welche das sind, haben wir versucht, im Rahmen dieser Publikation herauszuarbeiten. Sie entstand in Zusammenarbeit mit 24 Initiativen aus ganz Deutschland und umfasst eine Bestandsaufnahme der beteiligten Branchennetzwerke. Im zweiten Teil kommen ausgewählte Experten zu Wort, die entweder selbst Akteure der Kultur- und Kreativwirtschaft sind oder in ihrer alltäglichen Arbeit mit der Branche zu tun haben. Anhand konkreter Fragen geben sie eine Einschätzung zur Bedeutung, dem jetzigen Zustand der Kultur- und Kreativwirtschaft und zu den Zukunftsaussichten der Branche in Deutschland. Den Blickwinkel der Kultur- und Kreativschaffenden selbst beinhaltet das dritte Kapitel der Publikation. In einer Onlinebefragung wollten wir wissen, welche Themen für den einzelnen Akteur interessant sind und wie die bisherige Entwicklung sowie die individuellen Zukunftsperspektiven aussehen. Antworten gaben uns darauf über 600 Befragte aus ganz Deutschland.
Theory of Pairing Assisted Spin Polarization in Spin-Triplet Equal Spin Pairing: Origin of Extra Magnetization in Sr_2RuO_4 in Superconducting State
Creators: name: Miyake, Kazumasa
Publisher: name: arXiv
Year: 2014
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: It is shown that an extra magnetization is induced by an onset of the equal-spin-pairing of spin triplet superconductivity if the energy dependence of the density of states of quasiparticles exists in the normal state. It turns out that the effect is observable in Sr_2RuO_4 due to the existence of van Hove singularity in the density of states near the Fermi level, explaining the extra contribution in the Knight shift reported by Ishida et al. It is also quite non-trivial that this effect exists even without external magnetic field, which implies that the time reversal symmetry is spontaneously broken in the spin space.

title: Using bootstrap to compare the validity of PRO measures in discriminating among CKD patients
Creators: name: Deng, Nina
name: Ware Jr., John E.
Publisher: name: eScholarship@UMMS
Year: 2012

description: BACKGROUND: Patient-reported outcome (PRO) research requires valid and sensitive measures. Relative Validity (RV) offers an objective way to compare the validity of different PRO measures in discriminating groups of patients or occasions.

There is no significance test associated with RV. We applied bootstrap to estimate the confidence interval (CI) of RV to better interpret the differences in RV.

METHODS: The CKD-specific legacy (KDQOL Burden, Symptom, and Effect), generic health scales (SF-12), and Kidney Disease Impact Scale (KDIS) were administrated to 453 CKD patients. ANOVA-based RV coefficients were computed to compare how well each scale discriminated between three clinically-defined severity groups (Dialysis > Stage 3-5 > Transplant). Bootstrap was used to construct CI to determine whether the differences in RV were significant in comparisons between each scale and the best legacy standard- KDQOL Burden. Factors of sample size, number of bootstrap replications, bootstrap method were varied to investigate their impacts.

RESULTS: In comparison with KDQOL Burden (RV=1), using 95% CI, differences were non-significant for KDIS (RV=1.13), KDQOL Effect (RV=.99), SF-12 RP (RV=.77) and PF (RV=.70). SF-12 PCS (RV=.60) was at borderline. The other measures were significantly poorer in discriminating the patients.

Sample size played a substantial role. 300 patients for 3 groups greatly reduced the standard errors compared to 100 patients. A larger sample size greatly increased the power of detecting the differences.

The number of replications did not have consequential influence. The types of BCa and percentile intervals were preferred as all bootstrap distributions were skewed. The magnitude of chosen standard measure’s F-statistics appeared to have a noticeable impact on CI too.

CONCLUSIONS: Bootstrapping appears to be valuable in comparing the validity of PRO measures from a statistical perspective. The significance test of RV was affected by the sample size, magnitude of RV, and F-statistic of standard measure.

description: Background: Women are at increased risk of developing depression in the postpartum, a time of gonadal steroid flux. Abnormalities of gonadal steroids have been identified in some depressed women at times of reproductive flux. Gonadal steroids modulate corticocortical and corticolimbic functional connectivity (FC) in healthy, non-puerperal subjects; however there are no published studies of FC in postpartum depression (PPD).

Methods: Healthy comparison (HCS) (n=9) and medication-free subjects with unipolar PPD (n=8) were scanned at 3-9 weeks postpartum (using 3T Philips MRI) while ‘at rest’ with eyes open. Data analysis was carried out using SPM-8 and Data Processing Assistant for Resting-State fMRI (DPARSF) to perform seed based resting-state functional connectivity (rs-FC) analysis. Seeds were placed at bilateral anterior cingulate (ACC) and dorsolateral prefrontal cortices (DLPFC), hippocampi (HIPP) and amygdalae (AMYG). Correlation coefficients obtained from individual subject analysis were used in performing two-sample t-test to compare the two cohorts.

Results: Functional connectivity maps revealed a more distributed pattern of connectivity with each seed (i.e. ACC, DLPFX, HIPP, and AMYG) for HCS than PPD. In PPD subjects as compared to HCS, there was attenuation of rs-FC between corticocortical and corticolimbic areas.

Conclusions: In the early postpartum period, rs-FC patterns are disrupted in women with PPD in brain regions important for cognition, affect and the stress response. Larger studies are necessary to elucidate the role of disrupted neural connections in the pathophysiology of PPD and the potential modulatory role of gonadal steroids in women.

description: This paper presents the deductive formal verification of high-level properties of control systems with theorem proving, using the Why3 tool. Properties that can be verified with this approach include stability, feedback gain, and robustness, among others. For the systems, modelled in Simulink, we propose three main steps to achieve the verification: specifying the properties of interest over the signals within the model using Simulink blocks, an automatic translation of the model into Why3, and the automatic verification of the properties with theorem provers in Why3. We present a methodology to specify the properties in the model and a library of relevant assertion blocks (logic expressions), currently in development. The functionality of the blocks in the Simulink models are automatically translated to Why3 as theories and verification goals by our tool implemented in MATLAB. A library of theories in Why3 corresponding to each supported block has been developed to facilitate the process of translation. The goals are automatically verified in Why3 with relevant theorem provers. A simple first-order discrete system is used to exemplify the specification of the Simulink model, the translation process from Simulink to the Why3 formal logic language, and the verification of Lyapunov stability.

description: In this paper, the privacy of wireless transmissions is improved through the use of an efficient technique termed dynamic directional modulation (DDM), and is subsequently assessed in terms of the measure of information leakage. Recently, a variation of DDM termed low-power dynamic directional modulation (LPDDM) has attracted significant attention as a prominent secure transmission method due to its ability to further improve the privacy of wireless communications. Roughly speaking, this modulation operates by randomly selecting the transmitting antenna from an antenna array whose radiation pattern is well known. Thereafter, the modulator adjusts the constellation phase so as to ensure that only the legitimate receiver recovers the information. To begin with, we highlight some privacy boundaries inherent to the underlying system. In addition, we propose features that the antenna array must meet in order to increase the privacy of a wireless communication system. Last, we adopt a uniform circular monopole antenna array with equiprobable transmitting antennas in order to assess the impact of DDM on the information leakage. It is shown that the bit error rate, while being a useful metric in the evaluation of wireless communication systems, does not provide the full information about the vulnerability of the underlying system.

description: Objectives: Mood dysregulation in traumatized children may be misdiagnosed as bipolar disorder (BD) and conversely, the diagnosis of BD overlooked. Our aim is to characterize the relationship between trauma and mood dysregulation and pediatric BD.

Methods: We are assessing youths ages 8-18 who present with mood symptoms and past trauma divided into two groups: 1. Trauma+Unmodified DSM-IV-TR BD (T+BD) and 2. Trauma+Mood Disorder NOS (T+MD). Differences in clinical variables between groups are analyzed using t-tests for continuous and chi-square tests for categorical variables (α= 0.05).

Results: Age at onset of trauma for youth with T+BD (n=10) compared with T+MD (n=10) was similar (2.6±1.8 versus 3.3±1.9 years; p=0.4) as were types of trauma and number of incidents, and age at onset of mood symptoms (T+BD 7±2.5 versus T+MD 7.8±1.8 p=0.4). The T+BD group had higher scores on the sexual abuse subscale of the Childhood Trauma Questionnaire (p=0.04) and BPRS mania subscale (p=0.02), and higher total number of major depressive episodes (p=0.04) and manic episodes (p=0.03) per the KSCID. Youth with T+BD reported a trend toward higher rates of ideation to self-harm compared to youth with T+MD (p=0.08). Both groups had similar PTSD and ADHD symptoms, and similar number of psychotrophic medications (BD 3.6±2.9 MD 2.7±2.1 p=0.4). Finally, family history findings suggest a trend towards higher rates of any Axis I disorder in the T+BD families (p=0.07), and significantly higher rates of anxiety disorders (p=0.05), BD (p=0.04), and schizophrenia (p=0.02).

Conclusions: Results suggest differences in clinical presentation and higher rates of BD and schizophrenia in the T+BD families. Taken together, these preliminary results suggest potential biological and genetic vulnerabilities which may predispose children to develop specific mood disorders under certain circumstances; the ability to identify these children early on could change their prognostic trajectory.

description: The central detector in the MuSun experiment is a pad-plane time projection ionization chamber that operates without gas amplification in deuterium at 31 K; it is used to measure the rate of the muon capture process $μ^- + d \rightarrow n + n + ν_μ$. A new charge-sensitive preamplifier, operated at 140 K, has been developed for this detector. It achieved a resolution of 4.5 keV(D$_2$) or 120 $e^-$ RMS with zero detector capacitance at 1.1 $μ$s integration time in laboratory tests. In the experimental environment, the electronic resolution is 10 keV(D$_2$) or 250 $e^-$ RMS at a 0.5 $μ$s integration time. The excellent energy resolution of this amplifier has enabled discrimination between signals from muon-catalyzed fusion and muon capture on chemical impurities, which will precisely determine systematic corrections due to these processes. It is also expected to improve the muon tracking and determination of the stopping location.

The bond dimension of the MPO grows linearly with the locality of the charges. The MPO has more simple form than the local charges themselves, and their Catalan tree patterns naturally emerge from the matrix products. The MPO representation of local conserved quantities is generalized to the integrable $\mathrm{SU}(N)$ invariant spin chain.

description: Charge density wave (CDW) ordering has been an important topic of study for a long time owing to its connection with other exotic phases such as superconductivity and magnetism. The RTe3 (R = rare-earth elements) family of materials provides a fertile ground to study the dynamics of CDW in van der Waals layered materials, and the presence of magnetism in these materials allows to explore the interplay among CDW and long range magnetic ordering. Here, we have carried out a high-resolution angle-resolved photoemission spectroscopy (ARPES) study of a CDW material GdTe3, which is antiferromagnetic below 12 K, along with thermodynamic, electrical transport, magnetic, and Raman measurements. Our Raman spectroscopy measurements show the presence of CDW amplitude mode at room temperature, which remains prominent when the sample is thinned down to 4-layers by exfoliation. Our ARPES data show a two-fold symmetric Fermi surface with both gapped and ungapped regions indicative of the partial nesting. The gap is momentum dependent, maximum along G-Z and gradually decreases going towards G - M. Our study provides a platform to study the dynamics of CDW and its interaction with other physical orders in two- and three-dimensions.

Dear Magellanic Clouds, welcome back!

description: We propose a scenario in which the Large Magellanic Cloud (LMC) is on its second passage around the Milky Way. Using a series of tailored N-body simulations, we demonstrate that such orbits are consistent with current observational constraints on the mass distribution and relative velocity of both galaxies. The previous pericentre passage of the LMC could have occurred 5-10 Gyr ago at a distance >~100 kpc, large enough to retain its current population of satellites. The perturbations of the Milky Way halo induced by the LMC look nearly identical to the first-passage scenario, however, the distribution of LMC debris is considerably broader in the second-passage model. We examine the likelihood of current and past association with the Magellanic system for dwarf galaxies in the Local Group, and find that in addition to 10-11 current LMC satellites, it could have brought a further 4-6 galaxies that have been lost after the first pericentre passage. In particular, four of the classical dwarfs - Carina, Draco, Fornax and Ursa Minor - each have a ~50% probability of once belonging to the Magellanic system, thus providing a possible explanation for the ``plane of satellites'' conundrum.

description: Introduction: There are multiple accepted surgical techniques for placing thoracolumbar pedicle screws. Some surgeons use fluoroscopy to aid in placement of instrumentation, while others use fluoroscopy as confirmation of positioning after anatomic placement of screws. The purpose of this study is to evaluate the difference in radiation exposure imparted to the patient using a fluoroscopic-guided technique versus anatomic placement of screws.

Methods: A retrospective study evaluated 185 adult patients with non-percutaneous, posterior instrumented fusions over a four-year time period. For each patient, the fluoroscopy report was reviewed and the method of fluoroscopy utilization was ascertained from the patient’s operative report. Average seconds per screw inserted for each method was compared using a student’s t-test.

Results: 82 patients underwent thoracolumbar fusion by an anatomic technique, with an average of 5.72 screws (range 2-26) placed. The mean fluoroscopy time was 11.85 seconds (median 6 sec.) and the average time for placement of a single screw was 2.65 seconds. 103 patients underwent fluoroscopic-guided surgery. An average of 5.1 screws (range 2-12) were placed and the mean fluoroscopy time was 83.26 seconds per operation. The average time for placement of a single screw was 17.08 seconds.

Conclusion: Patients undergoing thoracolumbar fusion using the fluoroscopic-guided technique have increased radiation exposure, reaching 6.5 times the amount imparted using an anatomic technique, which is statistically significant (p<0.01).  Surgeons performing a large number of fluoroscopic-guided operations may have the potential to exceed annual radiation dose limits.

description: We derive a master equation from the exact stochastic Liouville von-Neumann (SLN) equation \cite{stockburger2002,wallsbook}. The latter depends on two correlated noises and describes exactly the dynamics of an oscillator (which can be either harmonic or present an anharmonicity) coupled to an environment at thermal equilibrium. The newly derived master equation is obtained by performing analytically the average over different noise trajectories. It is found to have a complex hierarchical structure that might be helpful to explain the convergence problems occurring when performing numerically the stochastic average of trajectories given by the SLN equation \cite{koch2008,koch2010}.

description: Introduction: Degenerative lumbar stenosis is common in adults and is frequently managed by surgical intervention after non-operative measures fail to relieve pain. Limited evidence-based information regarding optimal selection of patients for surgery exists. Current reform in healthcare policy has sparked significant interest in comparative effectiveness research with the goal of optimizing treatment strategies for common conditions such as degenerative lumbar stenosis. The purpose of this study is to quantify the effectiveness of surgical treatment of lumbar stenosis and to identify patient predictors of greatest improvement using patient reported measures of pain, physical function and quality of life.

Methods: A retrospective study evaluated 229 adult patients who underwent decompression with or without posterior lumbar fusion for treatment of lumbar stenosis over a two year time period. Patient reported outcomes were measured using the SF36 health survey. 146 patients had 6 month follow-up and 106 patients had one year follow-up. Variations in scores of the SF36 pain, mental component summary (MCS), and physical component summary (PCS) subscales were analyzed by multivariate linear regression analysis.

Results: At 6-12 months post-surgery, patients reported an improvement of 8 points in average pain (32.3 to 40.4), physical function (28.6 to 36.9), and PCS (29.0 to 36.9) subscales of the SF36. There was a 6 point average improvement in MCS scores (41.8 to 48.10). Greater post-operative pain was significantly associated with smoking (p

Conclusion: In general, surgical treatment for lumbar stenosis improves patient pain, quality of life, and physical function as indicated by substantial improvement in all subscales of the SF36 health survey. Predictive factors associated with poor pain relief after surgery include smoking, diabetes, the presence of instrumentation, and re-operation within a 12 month time period. Higher MCS scores are seen in older patients and those with an increase in physical function post-operatively. Predictive factors for poor MCS scores include revision surgery and mental health diagnosis. No specific predictors of PCS score were identified, most likely due to the complicated nature of the patient population with lumbar spinal stenosis. Further work is necessary to determine the ideal surgical candidate.

description: Introduction: In the active THR (total hip replacement) population, acetabular component stability is crucial for preventing implant failure. Titanium fiber metal coating is the most common material used in cementless THR. Trabecular metal, composed of porous tantalum, is designed to improve tissue infiltration and limit migration. It is unknown if tantalum offers an advantage over titanium in the biologic fixation of porous-coated acetabular shells. Radiostereometric analysis (RSA) provides highly precise measurements of micromotion that are otherwise not detectable by routine radiographs.

Methods: In this IRB approved, prospective, randomized, blinded study, 46 patients received a primary THR by a single surgeon. Each patient was randomized to receive a titanium (23) or tantalum (23) uncemented cup. Tantalum RSA markers were implanted around the polyethylene liner and into the patient’s femur and periacetabular bone. Also, patients received either a highly cross-linked (n=25) or a conventional liner (n=21). RSA examinations, Harris Hip, UCLA, WOMAC, SF-12 scores were obtained at 10 days, 6 months, and annually through 5 years.

Results: The randomized groups had comparable mean age, preoperative activity, and average BMI. The tantalum shells demonstrated less median translation than the titanium shells at each time-point, but there was no statistical difference between the two shells. At 6 months median translation of tantalum and titanium was -0.01mm and 0.04mm and remained stable with median translation of -0.02mm and 0.04mm at four years. Mean UCLA, WOMAC, Harris Hip, and SF-12 PCS and MCS scores improved similarly in both groups.

Conclusions: After THR, both patient cohorts had excellent clinical outcomes with statistically significant improvements in function and pain relief. Although tantalum porous-coated acetabular shells demonstrated less y-translation and y-rotation at all time points, there was no statistically significant difference in shell migration and both shells demonstrated excellent stability with minimal micromotion at four years.

description: A summary is presented for 130 galaxies observed with the Herschel PACS instrument to measure fluxes for the [CII] 158 um emission line. Sources cover a wide range of active galactic nucleus to starburst classifications, as derived from polycyclic aromatic hydrocarbon (PAH) strength measured with the Spitzer Infrared Spectrograph. Redshifts from [CII] and line to continuum strengths (equivalent width of [CII]) are given for the full sample, which includes 18 new [CII] flux measures. Calibration of L([CII)]) as a star formation rate (SFR) indicator is determined by comparing [CII] luminosities with mid-infrared [NeII] and [NeIII] emission line luminosities; this gives the same result as determining SFR using bolometric luminosities of reradiating dust from starbursts: log SFR = log L([CII)]) - 7.0, for SFR in solar masses per year and L([CII]) in solar luminosities. We conclude that L([CII]) can be used to measure SFR in any source to a precision of ~ 50%, even if total source luminosities are dominated by an AGN component. The line to continuum ratio at 158 um, EW([CII]), is not significantly greater for starbursts (median EW([CII]) = 1.0 um) compared to composites and AGN (median EW([CII]) = 0.7 um), showing that the far infrared continuum at 158 um scales with [CII] regardless of classification. This indicates that the continuum at 158 um also arises primarily from the starburst component within any source, giving log SFR = log vLv(158 um) - 42.8 for SFR in solar masses per year and vLv(158 um) in erg per sec.

description: Considerable attention has been paid to the study of the quantum geometry of nonrotating black holes within the framework of Loop Quantum Cosmology. This interest has been reinvigorated since the introduction of a novel effective model by Ashtekar, Olmedo, and Singh. Despite recent advances in its foundation, there are certain questions about its quantization that still remain open. Here we complete this quantization taking as starting point an extended phase space formalism suggested by several authors, including the proposers of the model. Adopting a prescription that has proven successful in Loop Quantum Cosmology, we construct an operator representation of the Hamiltonian constraint. By searching for solutions to this constraint operator in a sufficiently large set of dual states, we show that it can be solved for a continuous range of the black hole mass. This fact seems in favour of a conventional classical limit (at least for large masses) and contrasts with recent works that advocate a discrete spectrum. We present an algorithm that determines the solutions in closed form. To build the corresponding physical Hilbert space and conclude the quantization, we carry out an asymptotic analysis of those solutions, which allows us to introduce a suitable inner product on them.
