description: Transformers have been widely used for video processing owing to the multi-head self attention (MHSA) mechanism. However, the MHSA mechanism encounters an intrinsic difficulty for video inpainting, since the features associated with the corrupted regions are degraded and incur inaccurate self attention. This problem, termed query degradation, may be mitigated by first completing optical flows and then using the flows to guide the self attention, which was verified in our previous work - flow-guided transformer (FGT). We further exploit the flow guidance and propose FGT++ to pursue more effective and efficient video inpainting. First, we design a lightweight flow completion network by using local aggregation and edge loss. Second, to address the query degradation, we propose a flow guidance feature integration module, which uses the motion discrepancy to enhance the features, together with a flow-guided feature propagation module that warps the features according to the flows. Third, we decouple the transformer along the temporal and spatial dimensions, where flows are used to select the tokens through a temporally deformable MHSA mechanism, and global tokens are combined with the inner-window local tokens through a dual perspective MHSA mechanism. FGT++ is experimentally evaluated to be outperforming the existing video inpainting networks qualitatively and quantitatively.

description: We analyze a modified version of the Coleman-Hepp model, that is able to take into account energy-exchange processes between the incoming particle and the linear array made up of $N$ spin-1/2 systems. We bring to light the presence of a Wiener dissipative process in the weak-coupling, macroscopic ($N \rightarrow \infty$) limit. In such a limit and in a restricted portion of the total Hilbert space, the particle undergoes a sort of Brownian motion, while the free Hamiltonian of the spin array serves as a Wiener process. No assumptions are made on the spectrum of the Hamiltonian of the spin system, and no partial trace is computed over its states. The mechanism of appearance of the stochastic process is discussed and contrasted to other noteworthy examples in the literature. The links with van Hove's ``$λ^2 T$ limits are emphasized.

description: Using integral field spectroscopy we investigate the kinematic properties of 35 massive centrally-dense and compact star-forming galaxies (${\log{\overline{M}_*}}=11.1$, $\log{(Σ_\mathrm{1kpc})}>9.5$, $\log{(M_\ast/r_e^{1.5})}>10.3$) at $z\sim0.7-3.7$ within the KMOS$^\mathrm{3D}$survey. We spatially resolve 23 compact star-forming galaxies (SFGs) and find that the majority are dominated by rotational motions with velocities ranging from {$95-500$ km s$^{-1}$}. The range of rotation velocities is reflected in a similar range of integrated H$α$ linewidths, $75-400$ km s$^{-1}$, consistent with the kinematic properties of mass-matched extended galaxies from the full KMOS$^\mathrm{3D}$ sample. The fraction of compact SFGs that are classified as `rotation-dominated' or `disk-like' also mirrors the fractions of the full KMOS$^\mathrm{3D}$ sample. We show that integrated line-of-sight gas velocity dispersions from KMOS$^\mathrm{3D}$ are best approximated by a linear combination of their rotation and turbulent velocities with a lesser but still significant contribution from galactic scale winds. The H$α$ exponential disk sizes of compact SFGs are on average $2.5\pm0.2$ kpc, $1-2\times$ the continuum sizes, in agreement with previous work. The compact SFGs have a $1.4\times$ higher AGN incidence than the full KMOS$^\mathrm{3D}$ sample at fixed stellar mass with average AGN fraction of 76\%. Given their high and centrally concentrated stellar masses as well as stellar to dynamical mass ratios close to unity, the compact SFGs are likely to have low molecular gas fractions and to quench on a short time scale unless replenished with inflowing gas. The rotation in these compact systems suggests that their direct descendants are rotating passive galaxies.

description: Size selective flow-through chromatography (FC) was employed to adsorb impurities i.e. host cell proteins while large hepatitis B core antigen virus like particles (HB-VLPs) are recovered in the flow-through fraction. An inert polymer was grafted on adsorbents to improve the performance. The effect of feedstock conditions (size of target protein and protein load) and adsorbent design (adsorbent size, type of polymer chain and POEGMA architecture) on the performance of FC were investigated. Large size of HB-VLPs limits the protein load to 7 mg/ml, while optimal adsorbent design improved flow-through recovery by 5% compared to previous studies.

description: The statistical mechanics of flexible two-dimensional surfaces (membranes) appears in a wide variety of physical settings. In this talk we discuss the simplest case of fixed-connectivity surfaces. We first review the current theoretical understanding of the remarkable flat phase of such membranes. We then summarize the results of a recent large scale Monte Carlo simulation of the simplest conceivable discrete realization of this system \cite{BCFTA}. We verify the existence of long-range order, determine the associated critical exponents of the flat phase and compare the results to the predictions of various theoretical models.

description: Self-consistent treatment of time-dependent ionization in hydrodynamical calculations of the X-ray emission from young supernova remnants has been performed. The novel feature of the calculations is that K_alpha lines from species produced by inner-shell collisional ionization are included. Parameters of the shocked ejecta are found from fitting the model spectrum to the observed one. The application of the method to Tycho SNR using the classical deflagration model W7 for the explosion enables us to well reproduce the observed X-ray spectra and radial brightness profiles of the remnant.

Subjects: Racial profiling in law enforcement

description: Racial profiling is typically treated in the academic literature as just one more null hypothesis to be tested. An area that has potentially greater impact, and that has been relatively neglected in the literature, is the perception among citizens that their local law enforcement agency engages in racial profiling. The current study examines the relationship between the perception of racial profiling, police legitimacy, and citizen's confidence in their municipal, county, and state governments. The level of impact of citizen's perceptions of police misconduct has on institutional legitimacy is of import to police administrators and policy makers alike. This dissertation is comprised of two major sections that look at different aspects of institutional legitimacy. The first examines the impact that the perception of racial profiling and attributions of procedural fairness and justice has upon citizen's satisfaction with their local police agencies and among individual police officers. Multivariate analysis revealed that the perception of racial profiling and broad attributions of procedural justice had a significant impact upon citizen satisfaction with law enforcement at both the agency and individual levels of analysis. The next section examines citizen confidence in their municipal, county, and state government institutions. The most significant finding was clear evidence of a ripple effect where citizen attributions of confidence in one institution influenced confidence in the system as a whole. In particular, the perception of racial profiling and police legitimacy were highly influential in determining citizen confidence in their governmental institutions. This finding strongly suggests that problems (even the perception of one) such as racial profiling are not merely "police" problems but governmental ones. Public agencies do not operate in a vacuum and criminal justice agencies are no exception. The findings reported here give strong support to community and partnership-based approaches to crime control such as community oriented or problem oriented policing.

description: Compositionally complex alloys hold the promise of simultaneously attaining superior combinations of properties, such as corrosion resistance, light-weighting, and strength. Achieving this goal is a challenge due in part to a large number of possible compositions and structures in the vast alloy design space. High-throughput methods offer a path forward, but a strong connection between the synthesis of an alloy of a given composition and structure with its properties has not been fully realized to date. Here, we present the rapid identification of corrosion-resistant alloys based on combinations of Al and Cr in a base Al-Co-Cr-Fe-Ni alloy. Previously unstudied alloy stoichiometries were identified using a combination of high-throughput experimental screening coupled with key metallurgical and electrochemical corrosion tests, identifying alloys with excellent passivation behavior. The alloy native oxide performance and its self-healing attributes were probed using rapid tests in deaerated 0.1 mol/L H2SO4. Importantly, a correlation was found between the electrochemical impedance modulus of the exposure-modified air-formed film and self-healing rate of the CCAs. Multi-element extended x-ray absorption fine structure analyses connected more ordered type chemical short-range order in the Ni-Al 1st nearest-neighbor shell to poorer corrosion resistance. This report underscores the utility of high throughput exploration of compositionally complex alloys for the identification and rapid screening of a vast stoichiometric space.

description: It is rarely reported that collinear antiferromagnetic (AFM) metals can have anomalous Hall effect (AHE). In this letter, based on symmetry analysis and the first-principles electronic structure calculations, we predict that two existing collinear antiferromagnets Nb$_{2}$FeB$_{2}$ and Ta$_{2}$FeB$_{2}$, whose Néel temperatures are above room temperature, have very large AHE with anomalous Hall conductance (AHC) -100 $Ω^{-1}$ cm$^{-1}$ and $-54Ω^{-1}$ cm$^{-1}$, respectively. We further complete the symmetry resquirements for realizing the AHE in collinear antiferromagnetism.

description: My next-door neighbour has a relative who served and died in World War II. His name was John Green and he is my neighbour's uncle (on his mother's side of the family). He never met his uncle, as he died before he was born. His uncle was his mother's eldest brother and they lived at 158 Plodder Lane in Farnworth, Lancashire. In his early life, John worked at Harrowby Street Mill, a cotton mill, in Farnworth. My neighbour's mother said he was a doting big brother and, when he came home from leave, he always took her dancing and she was fond of him. She also said she remembered he had a girlfriend before he joining the army. He was conscripted into the army in 1940. He was in the 7th Green Howards Battalion and served as a Private, which is the lowest rank. He fought in the North Africa campaign for ten months. Africa was the only area where the Allies could fight the Germans on the ground in 1941-43. It was vital that the Allies protected the Suez Canal as this was a major shipping route for them. Private John Green (see photo with his army friends, he is bottom middle) found the army a great adventure; travelling from England (where he always lived), he got to see new and exciting places, but he always worried about dying whilst he was out at war. He travelled by boat from Liverpool to Alexandria in Egypt. While he was there, he visited Cairo and bought a new wallet (see photos). This took him through the dangerous Mediterranean Sea, past Malta, which was being bombed by the Luftwaffe. Private John Green was a soldier in the infantry and had been fighting in Tunisia when he was shot during battle and died from his wounds on 6 April 1943. His mother received a letter from the King and a notice was placed in a newspaper (See photo of newspaper clipping and photo of the King's letter). He was buried at the Christian Cemetery in Sfax, Tunisia (See photo of his grave). After Private John Green's death, a letter was sent home to his mother from the Under Secretary of State for War awarding her son with a service medal. My neighbour has all of his three medals he received during World War II (see photo); they were the 1939-45 Star (given to everyone who fought/served in WW2 for the British Army), the Africa Star (as he fought in Africa) and his War Medal.

My neighbour also has a telegraph that Private John Green had sent to his mother during his time in the war, saying he was coming home at 5.30pm; the telegraph does not have a date on but we believe this is the last one he sent before he died (see photo). The North African campaign ended on 13 May 1943, which meant that Private John Green almost made it to the end of the campaign, which is so unfortunate, but he will always be remembered as a hero!

description: Following extensive tests on analytical toy-catalogues (paper III), we present the results of a more realistic study over a 711 deg2 template-based cosmological simulation. Dark matter halos from the Aardvark simulation have been ascribed luminosities, temperatures and core-radii, using local scaling relations and assuming self-similar evolution. Predicted X-ray sky-maps are converted into XMM event lists using an instrumental simulator. The XXL pipeline run on the resulting sky images, produces an 'observed' cluster catalogue over which the tests have been performed. This allowed us to investigate the relative power of various combinations of count-rate, hardness-ratio, apparent-size and redshift information. Two fitting methods were used : a traditional MCMC approach and a simple minimisation procedure (Amoeba) whose mean uncertainties are a posteriori evaluated by means of synthetic catalogues. Results were analysed and compared to the predictions from a Fisher analysis (FA). For this particular catalogue realisation, assuming perfectly known scaling relations, the CR-HR combination gives $σ_8$ and $Ω_m$ at the 10% level, while CR-HR-r$_c$-z improves this to $\leq$ 3%. Adding a second hardness ratio improves results from the CR-HR1-r$_c$ combination, but to a lesser extent than adding redshift information. When all coefficients of the M-T relation (including scatter) are also fitted, cosmological parameters are constrained to within 5-10%, and larger for the M-T coefficients (up to a factor of two for the scatter). Errors returned by the MCMC, by Amoeba, and by FA predictions, are in most cases in excellent agreement and always within a factor of two. We also study the impact of the scatter of the M-Rc relation on the number of detected clusters: for the cluster typical sizes usually assumed, the larger the scatter, the lower the number of detected objects.

Field studies of sleep and performance in operational settings

Subjects: Sleep deprivation

description: Sleep loss leads to degraded alertness and cognitive performance. The management of factors influencing performance (time on task, sleep/wake history, and circadian rhythm) is important to workplace effectiveness. Contemporary work schedules limit sleep opportunities, leading to chronic sleep restriction. The present studies sought to examine the relationship between extended work hours, sleep, and subsequent performance. In Study 1, equipment maintenance personnel were studied during normal and extended work hours. Objective measures of sleep and performance demonstrated that extending work hours was associated with sleep loss. In this study, for each additional hour worked, an hour of sleep was lost. Contrary to expectations, objectively measured performance improved in the extended work hours condition. In Study 2, medical residents were studied while working both day shifts and a one month "night float" (extended night shift) rotation. In addition to the sleep and performance measures obtained in Study 1, two measures of learning and memory performance were administered. Medical residents obtained nearly equal amounts of objectively measured sleep while working both day and night float shifts; however, how this sleep was obtained differed between the day shift and night float conditions. Day shift sleep was obtained in a single, off shift, night time sleep bout. For the night float, some sleep was obtained in an off shift, daytime sleep bout. This daytime sleep bout was supplemented in the night float condition by napping on shift, while working the night float. By thus augmenting their truncated daytime sleep with night time, on shift naps, residents obtained near equivalent amounts of total sleep/24 hours working day shift and night float. Consistent with equivalent total sleep times between conditions, no differences in objective performance working day shift or night float were found. Field studies such as the ones presented here will be instrumental to forming the evidence-base of a fatigue risk management system. Such a system would allow for the management of sleep and duty times to sustain optimal performance in the workp

description: Gaussian processes provide a flexible, non-parametric framework for the approximation of functions in high-dimensional spaces. The covariance kernel is the main engine of Gaussian processes, incorporating correlations that underpin the predictive distribution. For applications with spatiotemporal datasets, suitable kernels should model joint spatial and temporal dependence. Separable space-time covariance kernels offer simplicity and computational efficiency. However, non-separable kernels include space-time interactions that better capture observed correlations. Most non-separable kernels that admit explicit expressions are based on mathematical considerations (admissibility conditions) rather than first-principles derivations. We present a hybrid spectral approach for generating covariance kernels which is based on physical arguments. We use this approach to derive a new class of physically motivated, non-separable covariance kernels which have their roots in the stochastic, linear, damped, harmonic oscillator (LDHO). The new kernels incorporate functions with both monotonic and oscillatory decay of space-time correlations. The LDHO covariance kernels involve space-time interactions which are introduced by dispersion relations that modulate the oscillator coefficients. We derive explicit relations for the spatiotemporal covariance kernels in the three oscillator regimes (underdamping, critical damping, overdamping) and investigate their properties. We further illustrate the hybrid spectral method by deriving covariance kernels that are based on the Ornstein-Uhlenbeck model.

description: We introduce a Julia implementation of the recently proposed Nevanlinna analytic continuation method. The method is based on Nevanlinna interpolants and, by construction, preserves the causality of a response function. For theoretical calculations without statistical noise, this continuation method is a powerful tool to extract real-frequency information from numerical input data on the Matsubara axis. This method has been applied to first-principles calculations of correlated materials. This paper presents its efficient and full-featured open-source implementation of the method including the Hamburger moment problem and smoothing.

description: Using the path integral representation of the density matrix propagator of quantum Brownian motion, we derive its asymptotic form for times greater than the localization time, $ (\hbar / γk T )^{\half}$, where $γ$ is the dissipation and $T$ the temperature of the thermal environment. The localization time is typically greater than the decoherence time, but much shorter than the relaxation time, $γ^{-1}$. We use this result to show that the reduced density operator rapidly evolves into a state which is approximately diagonal in a set of generalized coherent states. We thus reproduce, using a completely different method, a result we previously obtained using the quantum state diffusion picture (Phys.Rev. D52, 7294 (1995)). We also go beyond this earlier result, in that we derive an explicit expression for the weighting of each phase space localized state in the approximately diagonal density matrix, as a function of the initial state. For sufficiently long times it is equal to the Wigner function, and we confirm that the Wigner function is positive for times greater than the localization time (multiplied by a number of order 1).

description: The separation of trivalent f-elements such as Am and Cm is challenging due to the similarity in their chemistries. However, these separations are essential in radioanalytical chemistry. In this study, a separation procedure that allows for subsequent quantification of Am and Cm has been developed using commercially available materials. By careful consideration of the eluant, column length, and flow rate, near baseline separation of trace level Am from Cm has been obtained within 5 hours. These results may be modified and applied to capillary electrophoresis for smaller sample size and faster turn around time. For many radioactive samples, isotopic ratios can provide important clues about the provenance of the material. Ratios involving progenitor radionuclides aid in determining the age of a sample. For example, the ingrowth of 240Pu in a solution of 244Cm (t1/2 = 18.10 years) can be used to determine the amount of time that has elapsed since initial purification of the 244Cm. In this study, activity ratios of 244Cm and 240Pu have been determined for three different solutions, one of which is a legacy solution discovered during the closure of a research laboratory. Two of these have been measured by two independent procedures, radioanalytical method and mass spectrometric method. Results from two methods matched within uncertainties, and the age of unknown 244Cm solution has been determined. Pu samples can be classified differently depending on its Pu isotopic ratio (240Pu/239Pu). Also, 239Pu and 240Pu are radiogenic daughters of 243Cm and 244Cm, where the half lives of these are relatively short (29.1 and 18.1 years, respectively). Therefore, when a Pu sample co-exists with Cm source, the Pu isotopic ratio may be altered due to the decay of the parent Cm isotopes. This may cause difficulties of quantifying the isotopic ratio accurately. In this study, soils collected from F-area of Savannah River Site (SRS) have been investigated for Pu, Am, and Cm content as well as Pu isotopic ratio. Results showed that in some cases, the effect of Cm decay on Pu isotopic ratio is significant and the ratio was increased by as much as 100%.

description: Two-dimensional (2D) materials have considerably expanded the field of materials science in the last decade. Even more recently, various 2D materials have been assembled into vertical van der Waals heterostacks, and it has been proposed to combine them with other low- dimensional structures to create new materials with hybridized properties. Here, we demonstrate the first direct images of a suspended 0D/2D heterostructure incorporating $C_{60}$ molecules between two graphene layers in a buckyball sandwich structure. We find clean and ordered $C_{60}$ islands with thicknesses down to one molecule, shielded by the graphene layers from the microscope vacuum and partially protected from radiation damage during scanning transmission electron microscopy imaging. The sandwich structure serves as a 2D nanoscale reaction chamber allowing the analysis of the structure of the molecules and their dynamics at atomic resolution.
title: Understanding teacher leadership in context

Subjects: Teachers -- Professional relationships

description: The purpose of this qualitative, heuristic inquiry was two-fold: First, the study explored the lived experiences of four teacher leaders working in one comprehensive high school in a district where the researcher is superintendent. The second purpose was to learn from the experiences of the teacher leaders to inform district level actions that could develop structures and resources to support of the work of these and other current and emerging teacher leaders. The study addressed these questions: (a) What are the teacher leaders' personal and professional histories, qualities, and dispositions? (b) What is the nature and purpose of the work of these teacher leaders? (c) What are the contextual elements of the school district that either support or create challenges for the work of these teacher leaders? (d) What is the impact of the work of these teacher leaders? (e) What lessons can be drawn from the work of the teacher leaders to inform my actions as superintendent and improve school district structures and processes in order to support and encourage the work of these and other teacher leaders? Data were collected through individual and focus group in-depth interviews. In addition, since this was a heuristic study, the researcher also kept journal notes regarding learning from the perspective of the superintendent, actions that were taken as a result of this learning, and observations of various meetings and workshops related to these action. Based on this data, portraits of the four teacher leaders were developed to illustrate the teacher leaders' history and dispositions, the work they chose, and the context in which the work took place. Analysis of the data resulted in 19 themes organized into 4 major categories: Teacher leader dispositions, purposes of teacher leadership, means of teacher leadership, and context of teacher leadership. Based on this analysis, a conceptual framework for teacher leadership was developed that emphasizes the interactive, interdependent nature of the components of teacher leadership identified in this study. The heuristic approach resulted in a set of learning and actions taken with the school district. [The dissertation citations contained here are published with the permission of ProQuest llc.

ALICE continuous readout and data reduction strategy for Run3
Creators: name: Shahoyan, Ruben
Publisher: name: Zenodo

description: The ALICE experiment has originally been designed as a relatively low-rate experiment, in particular given the limitations of the Time Projection Chamber (TPC) readout system using MWPCs. This will not be the case anymore for LHC Run 3 scheduled to start in 2021. After the LS2 upgrades, including a new silicon tracker and a GEM-based readout for the TPC, ALICE will operate at a peak Pb-Pb collision rate of 50 kHz. To cope with this rate at least the TPC will be operated in continuous mode and all collisions will be read out, compressed and written to permanent storage without any trigger selection. The First Level Processing (FLP) site will receive continuous raw data at the rate of 3.4 TB/s and send to Event Processing Nodes (EPN) 10-20 ms packets at a rate of about 640 GB/s. EPNs will perform the data reconstruction and compression in a quasi-streaming and will send them for archival at the rate of 100 GB/s. Here we present the details of this synchronous stage of ALICE data processing.
Identification of Anaplasma marginale proteins up-regulated during infection of the tick vector

description: The transition between infection of the mammalian host and colonization of an arthropod vector is required for ongoing transmission of a broad array of pathogens, from viruses to protozoa. Understanding how this transition is mediated provides opportunities to disrupt transmission through either chemotherapy or immunization. We used two approaches to identify Anaplasma marginale proteins specifically up-regulated in the tick as compared to the mammalian host. We started with an unbiased proteome-wide screen to identify a list of candidates irrespective of localization within the bacterium or presumed function. Comparative mass spectrometric analysis of proteins separated by two-dimensional gel electrophoresis of uninfected and infected ISE6 cells and infected mammalian cells identified 15 proteins exclusively expressed or up-regulated in tick cells. All 15 had originally been annotated as hypothetical proteins. We confirmed quantitative up-regulation and expression in situ within the midgut epithelial and salivary gland acinar cells of vector ticks during successful transmission. The results support the hypothesis that A. marginale gene expression is regulated by the specific host environment and, in a broader context, that the core genome evolved in the arthropod vector with differential regulation allowing adaptation to mammalian hosts. In the second part we used a predictive approach. We predicted based on the reported nuclear translocation of Anaplasma phagocytophilum AnkA and Erhlichia chaffeensis p200 that the expression of A. marginale AnKA (AM705) would either be tick stage-specific or significantly upregulated in nucleated tick cells as compared to non-nucleated erythrocytes. In addition we predicted that AM705 would translocate to the host cell nucleus. We included in the analysis the other A. marginale genes with the ankyrin repeat motif; AM926 and AM638. While all the proteins were expressed in the tick stage, only AM638 was tick stage-specific. Contrary to our prediction the expression of AM705 was significantly higher in erythrocytes compared to ISE6 cells. AM926 was expressed at similar levels between ISE6 cells and erythrocytes. Using monoclonal antibodies specific to each protein in double immunofluorescence labeling we found that none of the proteins translocated to the host cell nucleus.All these findings advance our understanding of pathogen mammalian host-tick vector transition.

description: Cosmological models have granted dwarf galaxies a key role: their properties constrain the distribution of dark matter and the physical evolution of their hosts. There is increasing evidence that objects with masses of dwarf galaxies form in the tidal tails of colliding galaxies and speculations that they could become satellite-like galaxies around their progenitors and thus be cosmologically important. Yet, whether these "Tidal Dwarf Galaxies" (TDGs) candidates are really long-lived and not only present in young interacting systems is still an open question to which numerical simulations may give answers. We present a set of 96 simulations of colliding galaxies with various mass ratios and encounter geometries, and statistically study the evolution of their TDG candidates. Among the 593 substructures initially identified in tidal tails, about 75% fall back onto their progenitor or are disrupted in a few 10^8 years. The remaining 25% become long-lived bound objects that typically survive more than 2Gyr with masses above 10^8 M_sun. These long-lived, satellite-like objects, are found to form in the outer most regions of the tidal tails. We infer several basic properties that dwarf galaxies should meet to have a tidal origin and apply these criteria to the Local Group dwarfs. We also find that the presence of TDGs would foster the anisotropy observed in the distribution of satellite galaxies around their host. Identifying the conditions required for interacting systems to form long-lived tidal dwarfs, we roughly estimate their contribution to the overall population of dwarfs. We conclude that a small but significant fraction of them - typically a few percent, and possibly more in dense environments or around early-type galaxies - could be of tidal origin.
