description: Since anatomic MRI is presently not able to directly discern neuronal loss in Parkinson's Disease (PD), studying the associated functional connectivity (FC) changes seems a promising approach toward developing non-invasive and non-radioactive neuroimaging markers for this disease. While several groups have reported such FC changes in PD, there are also significant discrepancies between studies. Investigating the reproducibility of PD-related FC changes on independent datasets is therefore of crucial importance. We acquired resting-state fMRI scans for 43 subjects (27 patients , 16 controls) and compared the observed FC changes with those obtained in 2 independent datasets, one made available by the PPMI consortium and a second one by the group of Tao Wu. Unfortunately, PD-related functional connectivity changes turned out to be non-reproducible across datasets. This could be due to disease heterogeneity, but also to technical differences. To distinguish between the two, we devised a method to directly check for disease heterogeneity using random splits of a single dataset. Since we still observe non-reproducibility in a large fraction of random splits of the same dataset, we conclude that functional heterogeneity may be a dominating factor behind the lack of reproducibility of FC alterations in different rs-fMRI studies of PD. While global PD-related functional connectivity changes were non-reproducible across datasets, we identified a few individual brain region pairs with marginally consistent FC changes across all three datasets. However, training classifiers on each one of the 3 datasets to discriminate PD scans from controls produced only low accuracies on the remaining two test datasets. Moreover, classifiers trained and tested on random splits of the same dataset (which are technically homogeneous) also had low test accuracies, directly substantiating disease heterogeneity.

Entangled Photons and Phonons via Inter-Modal Brillouin Scattering

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We explore the possibility of the formation of photon-phonon entangled states in nanoscale wires by exploiting stimulated inter-modal Brillouin scattering of co-propagating photons that belong to distinct spatial optical modes. Inside nanowires, the photon-phonon coupling is significantly enhanced owing to radiation pressure. The Stokes and anti-Stokes processes are decoupled as they involve different phonon modes that lead to symmetry breaking, which results from different phase-matching requirements. For the Stokes process photon-phonon pairs are annihilated or created, in the presence of a classical pump field, and for the anti-Stokes process we obtain coherent oscillations between photons and phonons. The appearance of entangled states can extend the use of nanowires, for example, those made of silicon, into quantum information processing involving photons and phonons in a setup that can be easily integrated into an on-chip network.

description: This study aimed at assessing the practice of performance management system and examined its impact on employees' organizational commitment in Fitche Hospital. The questionnaires were distributed to 152 sample employees of the study and 145 were returned and used for analysis. Explanatory survey design using quantitative method was used. The participants of the study were selected using probability sampling method specifically stratified random sampling on the basis of the Hospital's business unit category. The data collected from respondents through questionnaire were analyzed using descriptive statistics such as mean and standard deviation, Pearson's correlation analysis, multiple regression analysis and independent samples t-test with the help of SPSS version 21. The descriptive result indicates that all the stages of performance management system rated below moderate except prerequisite. The findings also revealed that employees score more on continuance commitment, affective commitment and normative commitment respectively. The result of Pearson's correlation found that except performance planning all stages of performance management system have positive and significant relationship with each dimension of employees' organizational commitment. On the other hand, multiple regression result shows, except performance planning all stages of performance management system have statistically significant influence on employees' organizational commitment. It was also found that performance management system stages differ in their influence on each dimension of organizational commitment. Furthermore, there is significant difference between technical and non-technical staffs on implementation of PMS. However, there is no statistically significant difference between the staff members regarding their level of organizational commitment. The study recommends that performance management system should be clear, transparent, easy to understand, fair, and real measurement of employees' performance to enhance employees' commitment. Also performance planning, performance execution and performance renewal and reconstructing have unique contribution. Therefore, management of the Hospital should mainly focus and use those stages to enhance employees' commitment level. Finally it is recommended that the hospital should identify and consider the factors that have been identified to have significant difference between the staffs.

description: Global epidemics, such as HIV as well as COVID-19, provide important windows into the political dimensions of health. They are complex events that involve not only viral transmission but also a wide range of social responses at community, national and international levels. This chapter examines responses to HIV and COVID-19 in comparative perspective, showing how these responses have been shaped by the broader social and historical context; how knowledge (as well as ignorance) about each pandemic has been generated and contested over time; and how negative responses in the form of ‘stigma’, prejudice and discrimination have been deployed (and challenged) in relation to both pandemics. In so doing, it explores how pandemics come to be defined as public health ‘emergencies’. The analysis we develop suggests that responses to both HIV and COVID-19 provide insights into the ways in which multiple forms of power are at play – and highlight the need to place emphasis not only on the social determinants of health, but also on what is best understood as the social and political determinants of death.

description: Image restoration under hazy weather condition, which is called single image dehazing, has been of significant interest for various computer vision applications. In recent years, deep learning-based methods have achieved success. However, existing image dehazing methods typically neglect the hierarchy of features in the neural network and fail to exploit their relationships fully. To this end, we propose an effective image dehazing method named Hierarchical Contrastive Dehazing (HCD), which is based on feature fusion and contrastive learning strategies. HCD consists of a hierarchical dehazing network (HDN) and a novel hierarchical contrastive loss (HCL). Specifically, the core design in the HDN is a hierarchical interaction module, which utilizes multi-scale activation to revise the feature responses hierarchically. To cooperate with the training of HDN, we propose HCL which performs contrastive learning on hierarchically paired exemplars, facilitating haze removal. Extensive experiments on public datasets, RESIDE, HazeRD, and DENSE-HAZE, demonstrate that HCD quantitatively outperforms the state-of-the-art methods in terms of PSNR, SSIM and achieves better visual quality.

description: We consider Real bundle gerbes on manifolds equipped with an involution and prove that they are classified by their Real Dixmier-Douady class in Grothendieck's equivariant sheaf cohomology. We show that the Grothendieck group of Real bundle gerbe modules is isomorphic to twisted KR-theory for a torsion Real Dixmier-Douady class. Using these modules as building blocks, we introduce geometric cycles for twisted KR-homology and prove that they generate a real-oriented generalised homology theory dual to twisted KR-theory for Real closed manifolds, and more generally for Real finite CW-complexes, for any Real Dixmier-Douady class. This is achieved by defining an explicit natural transformation to analytic twisted KR-homology and proving that it is an isomorphism. Our model both refines and extends previous results by Wang and Baum-Carey-Wang to the Real setting. Our constructions further provide a new framework for the classification of orientifolds in string theory, providing precise conditions for orientifold lifts of H-fluxes and for orientifold projections of open string states.

description: We analyze the impact of different designs of COVID-19 related lockdown policies on economic loss and mortality using a micro-level simulation model, which combines a multisectoral closed economy with an epidemic transmission model. In particular, the model captures explicitly the (stochastic) effect of interactions between heterogeneous agents during different economic activities on virus transmissions. The empirical validity of the model is established using data on economic and pandemic dynamics in Germany in the first six months after the COVID-19 outbreak. We show that a policy inducing switches between a strict lockdown and a full opening-up of economic activity is strictly dominated by alternative policies, which implement either a much more cautious opening at the end of the lockdown or a more or less continuous light lockdown with only minor restrictions of economic activity. Furthermore, also the ex-ante variance of the economic loss suffered during the pandemic is substantially lower under these policies. Keeping the other policy parameters fixed, a variation of the consumption restrictions during the lockdown induces a trade-off between GDP loss and mortality. Finally, we study the robustness of these findings with respect to the occurrence of a more infectious virus mutation.

description: En el presente trabajo de investigación, se realizó el diseño conceptual de un reactor catalítico para depuración de vapores de crudo y nafta generados en el terminal Barú, de Oiltanking. En primer lugar, se seleccionó la reacción catalizada para combustión de metano acondiciones atmosféricas, sugiriendo una cinética elemental, a partir de quimisorción en la partícula. De esta manera, se delimitó el modelo matemático para un reactor catalítico, permitiendo elaborar la simulación en MATLAB®, en estado no estacionario, diferenciando los perfiles de concentración del metano, temperatura del fluido y temperatura de la partícula. Los resultados obtenidos en la simulación, fueron de una conversión de 99.90% de CH4, una temperatura de fluido de 1500 K y una temperatura de catalizador que alcanzó los 328,45 K; dejando en evidencia, que los resultados esperados con la operación, serán severos y con gran probabilidad de desactivar y fundir la partícula por las altas temperaturas manejadas. A raíz de ello, se recomendó realizar estudios experimentales que determinen el ajuste del modelo a escala industrial y a su vez hallen la velocidad de reacción a tales condiciones.Posteriormente, se planteó un diagrama de proceso que fue simulado en Unisim®, con el fin de determinar los tiempos en los cuales los equipos alcanzan la estabilidad, suministrando información importante para el diseño del sistema de control de la planta. Con base a esto, se desarrolló un estudio de pre-factibilidad económica, en el cual se calcularon y analizaron indicadores financieros, como el Costo Anual Uniforme Equivalente (CAUE) y Valor Presente Neto (VPN); arrojando como resultados un costo aproximado de inversión inicial para el diseño de $ 1.343.499.443,44; un costo anual para la planta a lo largo de una vida útil de 10 años de $169.423.644 y un CAUE y VPN de -$242.456.834,9 y $-2.250.904.562, respectivamenteDe lo anteriormente mencionado, se dictaminó, que implementar la tecnología de oxidación catalítica en la empresa, no es una iniciativa viable técnicamente, ni una inversión económica atractiva

description: Saponins are of higher molecular, nonvolatile and complex structure compounds; containing sapogenin and sugar. Saponins are extracted and sapogenin is isolated from the agave sisalana leaves, for use as pharmaceutical product starting material. In our country, there is shortage of active pharmaceutical ingredients. Ethiopia currently imports more than 90% active pharmaceutical ingredients, in order to cover its demand. The purpose of this study is to investigate the production possibility of a pharmaceutical starting material from agave leaves. Saponins were extracted from agave sisalana leaves juice by macerating with ethanol. Sapogenin was then isolated using acid hydrolysis. The yield of sapogenin was maximums at the hydrolysis parameters of 70 o C, 4M (Acid concentration) and 3:00hr and 30min and it was minimums at o 60 C, 2M and 1:00and 30min. Sapogenin is used for semi synthesis of cortisone and sex hormones drug formulation. Saponin and sapogenin were characterized by both qualitative (saponin foam test and Leiberman –burchard steroid test) and analytical methods (NMR, FTIR, and Spectroscopy photometer). The results of NMR Spectroscopy identified 27carbon atom. UV-Spectroscopy photometers peaks show sapogenin at 430 nm. The functional groups were determined by FTIR spectroscopy. Qualitative Saponin foam and steroid test results showed, that it created foam stable for 30min and its color changed from violate to blue green. Generally effectively extracts saponin by macerating from sisal leaves juice and isolation of sapogenin by acid hydrolysis of saponin. The yield of sapogenin was characterized by analytical and qualitative methods. The physicochemical characterization result shown as the hydrolysis yield is sapogenin.

description: Cryogenic semiconductor device models are essential in designing control systems for quantum devices and in benchmarking the benefits of cryogenic cooling for high-performance computing. In particular, the saturation of subthreshold swing due to band tails is an important phenomenon to include in low-temperature analytical MOSFET models as it predicts theoretical lower bounds on the leakage power and supply voltage in tailored cryogenic CMOS technologies with tuned threshold voltages. Previous physics-based modeling required to evaluate functions with no closed-form solutions, defeating the purpose of fast and efficient model evaluation. Thus far, only the empirically proposed expressions are in closed form. This article bridges this gap by deriving a physics-based and closed-form model for the full saturating trend of the subthreshold swing from room down to low temperature. The proposed model is compared against experimental data taken on some long and short devices from a commercial 28-nm bulk CMOS technology down to 4.2 K.

description: Bullying in schools has been a problem for as long as schools have existed. The issues are complex and research indicates that incidents of children being victimised are increasing. Two related studies are discussed in this report. Respondents for Study 1 are guidance officers from the Central Queensland region and issues of interest are: their perceptions regarding the frequency of bullying in schools; whom victims of bullying would be most likely to confide in; whether students would seek assistance from guidance officers if they are being bullied at school; and what strategies are successful for victims. For Study 2, respondents are students at a local Central Queensland high school. The focus is upon whom victims of bullying would be most likely to confide in. Results for both Studies 1 and 2 indicate that victims of bullying are more likely to tell their friends, and very unlikely to seek assistance from guidance officers, if they are being bullied at school. In Study 1 all respondents, further, report that bullying occurs in their respective schools and many feel that the most successful strategy for dealing with victims of bullying is to adopt a 'whole school' approach. Both previous studies and this present research indicate some hope for future action against bullying in schools. It is this researcher's opinion, however, that future prospects may be far more sombre and that intervention by guidance officers and school administrators will do little to alleviate the problem while dominance over others is encouraged by society.

Trapped ions beyond carrier and sideband interactions

description: Trapped ions driven by electromagnetic radiation constitute one of the most developed quantum technologies to date. The scenarios range from proof-of-principle experiments to on-chip integration for quantum information units. In most cases, these systems have operated in a regime where the magnitude of the ion-radiation coupling constant is much smaller than the trap and electronic transition frequencies. This regime allows the use of simple effective Hamiltonians based on the validity of the rotating wave approximation. However, novel trap and cavity designs now permit regimes in which the trap frequency and the ion-radiation coupling constant are commensurate. This opens up new venues for faster quantum gates and state transfers from the ion to a photon, and other quantum operations. From the theoretical side, however, there is not yet much known in terms of models and applications that go beyond the weak driving scenario. In this work, we will present two main results in the scenario of stronger drivings. First, we revisit a known protocol to reconstruct the motional Wigner function and expand it to stronger driving lasers. This extension is not trivial because the original protocol makes use of effective Hamiltonians valid only for weak drivings. The use of stronger fields or faster operations is desirable since experimental reconstruction methods of that kind are usually hindered by decoherence. We then present a model that allows the analytical treatment of stronger drivings and that works well for non-resonant interactions, which are generally out of the reach of the previous models.

description: We present the analysis of the morphological shape of Berkeley 17, the oldest known open cluster (~10 Gyr), using a probabilistic star counting of Pan-STARRS point sources, and confirm its core-tail shape, plus an antitail, previously detected with the 2MASS data. The stellar population, as diagnosed by the color-magnitude diagram and theoretical isochrones, shows many massive members in the cluster core, whereas there is a paucity of such members in both tails. This manifests mass segregation in this aged star cluster with the low-mass members being stripped away from the system. It has been claimed that Berkeley 17 is associated with an excessive number of blue straggler candidates. Comparison of nearby reference fields indicates that about half of these may be field contamination.

description: The novel weak-value-amplification (WVA) scheme of precision metrology is deeply rooted in the quantum nature of destructive interference between the pre- and post-selection states. And, an alternative version, termed as joint WVA (JWVA), which employs the difference-signal from the post-selection accepted and rejected results, has been found possible to achieve even better sensitivity (two orders of magnitude higher) under some technical limitations (e.g. misalignment errors). In this work, after erasing the quantum coherence, we analyze the difference-signal amplification (DSA) technique, which serves as a classical counterpart of the JWVA, and show that similar amplification effect can be achieved. We obtain a simple expression for the amplified signal, carry out characterization of precision, and point out the optimal working regime. We also discuss how to implement the post-selection of a classical mixed state. The proposed classical DSA technique holds similar technical advantages of the JWVA and may find interesting applications in practice.

description: Let a torus $T$ act smoothly on a compact smooth manifold $M$. If the rational equivariant cohomology $H^*_T(M)$ is a free $H^*_T(pt)$-module, then according to the Chang-Skjelbred Lemma, it can be determined by the $1$-skeleton consisting of the $T$-fixed points and $1$-dimensional $T$-orbits of $M$. When $M$ is an even-dimensional, orientable manifold with 2-dimensional 1-skeleton, Goresky, Kottwitz and MacPherson gave a graphic description of the equivariant cohomology. In this paper, first we revisit the even-dimensional GKM theory and introduce a notion of GKM covering, then we consider the case when $M$ is an odd-dimensional, possibly non-orientable manifold with $3$-dimensional $1$-skeleton, and give a graphic description of its equivariant cohomology.

description: We introduce fault-tolerant (FT) architectures for error correction with the XZZX cluster state based on performing measurements of two-qubit Pauli operators $Z\otimes Z$ and $X\otimes X$, or fusions, on a collection of few-body entangled resource states. Our construction is tailored to be effective against noise that predominantly causes faulty $X\otimes X$ measurements during fusions. This feature offers practical advantage in linear optical quantum computing with dual-rail photonic qubits, where failed fusions only erase $X\otimes X$ measurement outcomes. By applying our construction to this platform, we find a record high FT threshold to fusion failures exceeding $25\%$ in the experimentally relevant regime of non-zero loss rate per photon, considerably simplifying hardware requirements.

description: Eine sichere Energieversorgung in der Schweiz mit netto null Treibhausgasemissionen 2050 ist mit einem koordinierten Vorgehen über alle Energiesektoren realisierbar. Basis dafür sind ein starker Ausbau der erneuerbaren Stromproduktion im Inland und der Import synthetischer Brenn- und Treibstoffe. Eine vollständige Energieautarkie ist kaum möglich und wenn überhaupt nur mit sehr hohen Kosten.

description: Cucumis melo “Meloncella fasciata” is cultivated and appreciated locally for its unripe fruits. Seed production of these landraces rely on local farmers but heterogeneity limits rapid scalability of this crop. Plant micropropagation techniques may be an alternative method for propagation but their use is limited by genetic instability. We concentrated on organogenesis from cotyledonary nodes, applying the plant growth regulator 6-benzylaminopurine (BAP) combined with the antibiotic cefotaxime to reduce the negative effects of high cytokinin doses. It was observed that this antibiotic, in addition to limiting contamination, has a stimulatory effect on regeneration in several species including melon. Multiple shoot regeneration was achieved from explants within 30 days of cultivation. Explants regenerated adventitious shoots with all concentrations of BAP and cefotaxime, however efficiency varied significantly. Cefotaxime at a dose of 500 mg/L combined with BAP 0.5 mg/L induced an effect comparable to higher doses of BAP. Reducing BAP concentration was beneficial on shoot development, since excessive cytokinin concentrations can induce somaclonal variation. Thanks to the reduced quantity of BAP, no tetraploid cells could be observed in regenerated plants. We conclude that cefotaxime can be integrated in the propagation process providing multiple advantages including contamination control and reduced chromosomal instability.

Two-Level Structural Sparsity Regularization for Identifying Lattices and Defects in Noisy Images

description: This paper presents a regularized regression model with a two-level structural sparsity penalty applied to locate individual atoms in a noisy scanning transmission electron microscopy image (STEM). In crystals, the locations of atoms is symmetric, condensed into a few lattice groups. Therefore, by identifying the underlying lattice in a given image, individual atoms can be accurately located. We propose to formulate the identification of the lattice groups as a sparse group selection problem. Furthermore, real atomic scale images contain defects and vacancies, so atomic identification based solely on a lattice group may result in false positives and false negatives. To minimize error, model includes an individual sparsity regularization in addition to the group sparsity for a within-group selection, which results in a regression model with a two-level sparsity regularization. We propose a modification of the group orthogonal matching pursuit (gOMP) algorithm with a thresholding step to solve the atom finding problem. The convergence and statistical analyses of the proposed algorithm are presented. The proposed algorithm is also evaluated through numerical experiments with simulated images. The applicability of the algorithm on determination of atom structures and identification of imaging distortions and atomic defects was demonstrated using three real STEM images. We believe this is an important step toward automatic phase identification and assignment with the advent of genomic databases for materials.

Energy generation, conversion and storage (excl. chemical and electrical)

description: With the rapidly growing markets for electric vehicles and renewable energy systems, the complex duty cycles imposed by electric machines and power electronics components are now a common feature of battery service. As a result, lithium-ion, increasingly the battery of choice, must cope with superimposed Alternating Current (AC) across a broad range of frequencies. The main objective of this thesis is to investigate the effect of AC on the key processes that underpin LIB life performances.
The spectrum for commutative complex $K$-theory
Creators: name: Gritschacher, Simon
Publisher: name: arXiv

Subjects: subject: Algebraic Topology (math.AT)

subject: 19L99

description: We study commutative complex $K$-theory, a generalised cohomology theory built from spaces of ordered commuting tuples in the unitary groups. We show that the spectrum for commutative complex $K$-theory is stably equivalent to the $ku$-group ring of $BU(1)$ and thus obtain a splitting of its representing space $B_{com}U$ as a product of all the terms in the Whitehead tower for $BU$, $B_{com}U\simeq BU\times BU\langle 4\rangle \times BU\langle 6\rangle \times \dots .$ As a consequence of the spectrum level identification we obtain the ring of coefficients for this theory. Using the rational Hopf ring for $B_{com}U$ we describe the relationship of our results with a previous computation of the rational cohomology algebra of $B_{com}U$. This gives an essentially complete description of the space $B_{com}U$ introduced by A. Adem and J. Gómez.
description: 35 pages. This article replaces "The ring of coefficients for commutative complex $K$-theory". The results have been improved and the exposition streamlined, some results have been removed to appear in future work, some new results have been added, a mistake (previously in Lemma 4.7 and Corollary 4.8) has been corrected (the correct statement appears now as Proposition 5.2)
A Bayesian treatment of the German tank problem

description: The German tank problem has an interesting historical background and is an engaging problem of statistical estimation for the classroom. The objective is to estimate the size of a population of tanks inscribed with sequential serial numbers, from a random sample. In this tutorial article, we outline the Bayesian approach to the German tank problem, (i) whose solution assigns a probability to each tank population size, thereby quantifying uncertainty, and (ii) which provides an opportunity to incorporate prior information and/or beliefs about the tank population size into the solution. We illustrate with an example. Finally, we survey problems in other contexts that resemble the German tank problem.
