description: We study the structure of the flat space wavefunctional in scalar field theories with nonlinearly realized symmetries. These symmetries imply soft theorems that are satisfied by wavefunction coefficients in the limit where one of the external momenta is scaled to zero. After elucidating the structure of these soft theorems in the nonlinear sigma model, Dirac-Born-Infeld, and galileon scalar theories, we combine them with information about the singularity structure of the wavefunction to bootstrap the wavefunction coefficients of these theories. We further systematize this construction through two types of recursion relations: one that utilizes the flat space scattering amplitude plus minimal information about soft limits, and an alternative that does not require amplitude input, but does require subleading soft information.

description: Subject-matter experts typically think of their datasets as causes and effects between many variables, forming a large, complex causal system. Directed acyclic graphs (DAG), also called Bayesian networks, provide a natural way to conceptualize these systems. In contrast, regression modeling can provide strong evidence for the local, causal neighborhood of an outcome within the causal system, butproviding structure for the larger system is challenging with regression. Despite its value as exploratory data analysis or in conjunction with regression models to refine causal understanding, methods for estimating the causal structure underlying a dataset, causal discovery, are rare in fields such as epidemiology, possibly due to the difficulty handling data with continuous and discrete random variables.This thesis focuses on developing a causal discovery method for researchers whose data typically are comprised of both discrete and continuous variables. Its primarycontribution is the development of an estimator for graph divergence, the Kullback-Leibler divergence between the full, joint distribution and the Bayesian factorizationindicated by a DAG. Graph divergence is a generalization of conditional mutual information: it quantifies the ?t of a DAG to the data, with greater divergence indicating worse ?t and a divergence of zero indicating a perfect characterization ofthe conditional independence relationships among the variables. Its nearest neighbor approach gives the estimator the capability to handle mixed data. We show that the estimator is consistent and its convergence separately for the continuous and discrete case under some assumptions.Last, we demonstrate a way to use graph divergence with a greedy Markov equivalence search algorithm in practice. Though this work is not complete, we estimate causal relationships between personal demographics, sexual risk behaviors, and HIV Pre-exposure prophylaxis among men who have sex with men (MSM) on the American Men's Internet Survey data. This work may be able to inform publichealth initiatives and guidelines surrounding sexual health of MSM.

description: We introduce the Gaussian part of a compact quantum group $\mathbb{G}$, namely the largest quantum subgroup of $\mathbb{G}$ supporting all the Gaussian functionals of $\mathbb{G}$. We prove that the Gaussian part is always contained in the Kac part, and characterise Gaussian parts of classical compact groups, duals of classical discrete groups and $q$-deformations of compact Lie groups. The notion turns out to be related to a new concept of "strong connectedness" and we exhibit several examples of both strongly connected and totally strongly disconnected compact quantum groups.

Leveraging Context for Multi-Label Action Recognition and Detection in Video
Creators: name: Joao Antunes Martins
Publisher: name: Carnegie Mellon University
Year: 2020
Subjects: Computer Engineering

description: This thesis addresses video-based multi-person, multi-label, spatiotemporal action detection and recognition. This is a challenging problem because each person can be performing several actions at the same time (e.g. talking and walking), and simultaneously other actors can be performing different actions. We claim that these are problems where the use of contextual information (e.g. semantic descriptions of the scene) may lead to significant performance improvements. In this work, we develop several approaches to tackle this problem and validate them in challenging datasets. We propose a framework to integrateand test multiple sources of contextual information in video-based multi-person, multi-label, spatiotemporal action detection and recognition. We highlight six contributions,and that are collected in three publications (at different stages of publication at the time of this writing). The first contribution is a proposed Multisource Video Classification(MVC) framework that allows the combination of several sources of context information, for which we consider four types: actor centric input filtering (a way to focus attentionon the actor under analysis but still gather appearance information from the neighborhood), semantic neighbor context (a way to inform the model with the actions performed by nearby agents), object detection (how objects interacting with the actor can inform about its action) and pose data (how high level features extracted from the actor can help the classification process). The second contribution is a foveated approach to actor centric filtering for input selection that weights the appearance information in a decreasing way, from the center to the periphery of the actor bounding box. The third contribution is a novel encodingfor the semantic neighbor context and its custom classifier with spatial and temporal dependence. The fourth is a custom Hybrid Sigmoid-Softmax loss function for the multiclass/ multi-label case, that combines the cross-entropy loss typical of multi-class problems with the sum-of-sigmoids loss used in the multi label case. The fifth is the application of the developed methods to a challenging dataset with a large number of videos with mulivtiple agents performing multiple actions, with 80 heterogeneous and highly unbalanced classes. To allow research with reasonable computer power, we have created the mini-AVA, a partition of AVA that maintains temporal continuity and class distribution with only one tenth of the dataset size. The sixth contribution is a collection of ablation studies on alternative actor centric filters and semantic neighbor context classifiers. From this research we achieve a relative mAP improvement of 18:8% using our foveated actor centricfiltering, relative mAP improvement of 5% using our semantic neighbor context embedding and models, and a relative mAP improvement of 12:6% using our custom Hybrid Sigmoid-Softmax loss.

description: The urokinase type plasminogen activator (uPAR) is a three domain GPI-anchored cell surface receptor. uPAR expression is strongly up-regulated and represents a negative prognostic factor in various tumors, including hematologic malignancies. uPAR expression is post-transcriptionally regulated by RNA binding proteins (RBPs). RBPs bind specific sequences in the 3’untranslated region (3’UTR) of uPAR-mRNA, stabilizing or destabilizing the transcript. The 3’UTR of transcripts from a large number of genes includes target sequences also for small translational repressors RNAs (miRNAs). miRNAs play key roles in many cellular pathways; their aberrant expression is a common feature of various malignancies. We selected three miRNAs miR-146a, miR-335 and miR-622 that could bind the 3’UTR of uPAR-mRNA; these three miRNAs, as reported in literature, are expressed in CD34+ HSC or in acute myeloid leukemia (AML) cells and can act as oncosuppressors by inhibiting oncogene expression. We found that selected miRNAs regulate uPAR expression by directly targeting its 3’UTR in AML cell lines. Indeed, uPAR expression is reduced by their overexpression and increased by their specific inhibitors. Overexpression of selected miRNAs impaired cell migration, invasion and proliferation of AML cell lines. Interestingly, we found an inverse relationship between uPAR expression and miR- 146a and miR-335 levels in AML blasts. This suggests their possible role in regulating uPAR expression also in vivo. We also investigated the capability of uPAR-3’UTR to act as competing endogenous RNA (ceRNA). We showed that uPAR-3’UTR overexpression up-regulates uPAR expression and expression of other targets of selected miRNAs; these results suggest that uPAR-3’UTR may recruit selected miRNAs, allowing translation of their targets, thus acting as ceRNA.

description: Colormagnetic confinement as a natural component of the QCD confinement is explained and treated in the framework of the Field Correlator Method. For quarks and gluons in hadrons the effects of the colormagnetic confinement are discussed at zero temperature, where it contributes to the spectrum properties and can create its own bound states, while at nonzero temperature in the EoS of the quark gluon plasma the colormagnetic confinement plays a dominating role. Its properties in the QCD thermodynamics are discussed in detail.

description: Superhalo electrons appear to be continuously present in the interplanetary medium, even at very quiet times, with a power-law spectrum at energies above $\sim$2 keV. Here we numerically investigate the generation of superhalo electrons by magnetic reconnection in the solar wind source region, using the MHD and test particle simulations for both single X-line reconnection and multiple X-line reconnection. We find that the direct current electric field, produced in the magnetic reconnection region, can accelerate electrons from an initial thermal energy of T $\sim10^5$ K up to hundreds of keV. After acceleration, some of the accelerated electrons, together with the nascent solar wind flow driven by the reconnection, propagate upwards along the newly-opened magnetic field lines into the interplanetary space, while the rest move downwards into the lower atmosphere. Similar to the observed superhalo electrons at 1 AU, the flux of the upward-traveling accelerated electrons versus energy displays a power-law distribution at $\sim$ 2 $-$ 100 keV, $f(E) \sim E^{-δ}$, with a $δ$ of $\sim$ 1.5 $-$ 2.4. For single (multiple) X-line reconnection, the spectrum becomes harder (softer) as the anomalous resistivity parameter $α$ (uniform resistivity $η$) increases. These modeling results suggest that the acceleration in the solar wind source region may contribute to superhalo electrons.

description: Multiple proxies in three sediment cores from Northwestern Baffin Bay document the timing of Lancaster Sound Ice Stream (LSIS) retreat that led to Arctic–Atlantic throughflow in Parry Channel, an important source of freshwater that can impact the Atlantic Meridional Overturning Circulation. The Late Glacial to Holocene timing of ice retreat and channel opening and the responses of the regional ocean environment to these events are presented. We use quantitative mineral composition, foraminiferal assemblages, biogenic silica, ice-rafted debris (IRD), and 14C-based age models to document and date the events and environmental changes occurring during deglaciation of this major marine channel. Findings show that retreat of the LSIS into Lancaster Sound occurred before ~15.3 cal ka BP, about 800 years before the onset of major iceberg calving events from the LSIS, named the Baffin Bay Detrital Carbonate events (BBDC 1 and BBDC 0). The end of BBDC 0 occurred at ~10.6 cal ka BP, which coincides with the opening of Parry Channel. A marine environment productive of calcareous benthic and planktic foraminifera, with diminished meltwater, seasonal sea ice, warmer summer temperatures, and inflowing, nutrient-rich Arctic surface water characterizes the interval between the opening of Parry Channel and the opening of Nares Strait. Paired planktic and benthic 14C ages over this 2,200-year interval show diminishing age offsets suggesting progressive mixing of the upper ~850–900 m of the water column. The opening of Nares Strait by ~8.2 cal ka BP coincides with increased biogenic silica in the form of abundant, large centric diatoms and dissolution of CaCO3. The paucity of calcareous organisms after 8.2 cal ka BP resulted in poor chronological control in the cores to interpret changing environments after 8.2 cal ka BP.

description: The Milky Way is believed to host hundreds of millions of quiescent stellar-mass black holes (BHs). In the last decade, some of these objects have been potentially uncovered via gravitational microlensing events. All these detections resulted in a degeneracy between the velocity and the mass of the lens. This degeneracy has been lifted, for the first time, with the recent astrometric microlensing detection of OB110462. However, two independent studies reported very different lens mass for this event. Sahu et al. (2022) inferred a lens mass of 7.1 $\pm$ 1.3 Msun, consistent with a BH, while Lam et al. (2022) inferred 1.6-4.2 Msun, consistent with either a neutron star or a BH. Here, we study the landscape of isolated BHs formed in the field. In particular, we focus on the mass and center-of-mass speed of four sub-populations: isolated BHs from single-star origin, disrupted BHs of binary-star origin, main-sequence stars with a compact object companion, and double compact object mergers. Our model predicts that most ($\gtrsim$ 70%) isolated BHs in the Milky Way are of binary origin. However, non-interactions lead to most massive BHs ($\gtrsim$ 15-20 Msun) being predominantly of single origin. Under the assumption that OB110462 is a free-floating compact object we conclude that it is more likely to be a BH originally belonging to a binary system. Our results suggest that low-mass BH microlensing events can be useful to understand binary evolution of massive stars in the Milky Way, while high-mass BH lenses can be useful to probe single stellar evolution.

description: Massive stars show a variety of spectral variability: presence of discrete absorption components in UV P-Cygni profiles, optical line profile variability, X-ray variability, radial velocity modulations. Our goal is to study the spectral variability of single OB stars to better understand the relation between photospheric and wind variability. For that, we rely on high spectral resolution, high signal-to-noise ratio optical spectra collected with the spectrograph NARVAL on the Telescope Bernard Lyot at Pic du Midi. We investigate the variability of twelve spectral lines by means of the Temporal Variance Spectrum (TVS). The selected lines probe the radial structure of the atmosphere, from the photosphere to the outer wind. We also perform a spectroscopic analysis with atmosphere models to derive the stellar and wind properties, and to constrain the formation region of the selected lines. We show that variability is observed in the wind lines of all bright giants and supergiants, on a daily timescale. Lines formed in the photosphere are sometimes variable, sometimes not. The dwarf stars do not show any sign of variability. If variability is observed on a daily timescale, it can also (but not always) be observed on hourly timescales, albeit with lower amplitude. There is a very clear correlation between amplitude of the variability and fraction of the line formed in the wind. Strong anti-correlations between the different part of the temporal variance spectrum are observed. Our results indicate that variability is stronger in lines formed in the wind. A link between photospheric and wind variability is not obvious from our study, since wind variability is observed whatever the level of photospheric variability. Different photospheric lines also show different degrees of variability.

The interaction with the radiation field is modeled by a force term {\it à la} Poynting-Robertson entering the equations of motion given by the 4-momentum density of radiation observed in the particle's rest frame with a multiplicative constant factor expressing the strength of the interaction itself. Explicit analytical solutions are obtained. Scattering of fields by the electromagnetic wave, i.e., scalar (spin 0), massless spin $\frac12$ and electromagnetic (spin 1) fields, is studied too.

description: BACKGROUND AND OBJECTIVES: Following the publication of Point-of-Care-Ultrasound (POCUS) curriculum guidelines from the American Academy of Family Physicians in 2016, there has been a rapid expansion in POCUS curricula across family medicine departments in the US. There is growing appreciation for the potential role of POCUS in enhancing the clinical care family physicians provide to patients. The primary aim of our study was to evaluate the utilization of POCUS in outpatient clinic care across Family Medicine departments nationwide and to identify perceived or realized barriers in integrating POCUS use for clinic care. METHODS: The questions were part of a larger omnibus survey of US Department of Family Medicine chairs, conducted by the Council of Academic Family Medicine Educational Research Alliance (CERA) between August 6 to August 31, 2021. RESULTS: 81% of departments have at least 1 POCUS-trained faculty, with 44% of departments using POCUS in some ambulatory clinical care. Currently, only 6% have established billing for the POCUS they perform. Faculty time, as well as funding, for POCUS training were seen as 2 primary barriers. The purchasing of equipment and billing for POCUS were described by FMCs as difficult. CONCLUSIONS: As POCUS use continues to rise in Family Medicine, it is imperative to create a more efficient and less hindered road to growth. Collaboration across departments to share best practices in training, purchasing equipment and billing for POCUS will be important to facilitate high-quality POCUS access for our patients.

description: Recent studies reveal a pressure induced transition from a paramagnetic tetragonal phase (T) to a collapsed tetragonal phase (CT) in $CaFe_2As_2$, which was found to be superconducting with non-hydrostatic pressure at low temperature. We have investigated the effects of electron correlation and local fluctuating moment in both tetragonal and collapsed tetragonal phases of the paramagnetic $CaFe_2As_2$ using self consistent DFT+DMFT with continuous time quantum Monte Carlo as the impurity solver. From the computed optical conductivity, we find a gain in the optical kinetic energy due to the loss in Hund's rule coupling energy in the CT. We find that the transition from T to CT turns $CaFe_2As_2$ from a bad metal into a good metal. Computed mass enhancement and local moments also show significant decrease in the CT, which confirms the suppression of the electron correlation in the CT phase of $CaFe_2As_2$.

Microplastics (MP) were separated from the wastewater matrix by oxidative treatment and density separation and analyzed by Raman microspectroscopy. Due to precautionary measures, procedural blanks were very low with a mean number of 4.3 ± 2.7 MPP and 0.88 ± 0.56 MPF within eight blank samples. The municipal WWTPs were able to eliminate 99.2% ± 0.29% and 99.4% ± 0.15% of MP in the sand filtration stage. The sand filtration of a PVC manufacturer eliminated 99.2%–99.9%

description: In this work, we report numerical results on the flow instability and bifurcation of a viscoelastic fluid in the upstream region of a confined cylinder in a narrow channel. Two-dimensional direct numerical simulations based on the FENE-P model (the finite-extensible nonlinear elastic model with the Peterlin closure) are conducted with numerical stabilization techniques. Our results show that the macroscopic viscoelastic constitutive relation can capture the viscoelastic upstream instability reported in previous experiments for low-Reynolds-number flows. The numerical simulations reveal that the non-dimensional recirculation length ($L_D$) is affected by the cylinder blocking rate ($BR$), the Weissenberg number ($Wi$), the viscosity ratio ($β$), and the maximum polymer extension ($L$). Close to the onset of upstream recirculation, depending on the values of $L$ and $β$, the bifurcation can be supercritical or subcritical. $β$ has a nonlinear influence on the upstream recirculation length. This work contributes to our theoretical understanding of this new instability mechanism in viscoelastic wake flows.

description: Purpose: Assessment of strained voice quality is difficult due to the weak reliability of auditory-perceptual evaluation and lack of strong acoustic correlates. This study evaluated the contributions of relative fundamental frequency (RFF) and mid-to-high frequency noise to the perception of strain.Method: Stimuli were created using recordings of speakers producing /ifi/ with a comfortable voice and with maximum vocal effort. RFF values of the comfortable voice samples were synthetically lowered, and RFF values of the maximum vocal effort samples were synthetically raised. Mid-to-high frequency noise was added to the samples. Twenty listeners rated strain in a visual sort-and-rate task. The effects of RFF modification and added noise on strain were assessed using an analysis of variance; intra- and interrater reliability were compared with and without noise.Results: Lowering RFF in the comfortable voice samples increased their perceived strain, whereas raising RFF in the maximum vocal effort samples decreased their strain. Adding noise increased strain and decreased intra- and interrater reliability relative to samples without added noise.Conclusions: Both RFF and mid-to-high frequency noise contribute to the perception of strain. The presence of dysphonia may decrease the reliability of auditory-perceptual evaluation of strain, which supports the need for complementary objective assessments.

description: Currently, parameters for neither mode- nor route choice are available in terms of bike-sharing, resulting in a lack of knowledge to implement bike-sharing systems in transport demand models. Estimating such parameters is the aim of a stated preferences experiment on choices between shared bikes, public transport, and private motorized transport. Preliminary results of a multinomial logit model on a sample of 69 non-users and users of bike-sharing systems are presented. For all modes, travel costs have a negative effect on the associated utility of transport mode. Travel time shows a negative effect for all modes, while for shared bike and public transport access and egress time has a stronger effect than time in the vehicle. For bicycling, street type has no effect, while asphalt is the most preferred type of street surface. The utility of public transport is lower with higher utilized capacity.

description: We generalize the modern theory of electric polarization to the case of one-dimensional non-Hermitian systems with line-gapped spectrum. In these systems, the electronic position operator is non-Hermitian even when projected into the subspace of states below the energy gap. However, the associated Wilson-loop operator is biorthogonally unitary in the thermodynamic limit, thereby leading to real-valued electronic positions that allow for a clean definition of polarization. Non-Hermitian polarization can be quantized in the presence of certain symmetries, as for Hermitian insulators. Different from the latter case, though, in this regime polarization quantization depends also on the type of energy gap, which can be either real or imaginary, leading to a richer variety of topological phases. The most counter-intuitive example is the 1D non-Hermitian chain with time-reversal symmetry only, where non-Hermitian polarization is quantized in presence of an imaginary line-gap. We propose two specific models to provide numerical evidence supporting our findings.

description: Low-energy electron microscopy (LEEM) taken as intensity-voltage (I-V) curves provides hyperspectral images of surfaces, which can be used to identify the surface type, but are difficult to analyze. Here, we demonstrate the use of an algorithm for factorizing the data into spectra and concentrations of characteristic components (FSC3) for identifying distinct physical surface phases. Importantly, FSC3 is an unsupervised and fast algorithm. As example data we use experiments on the growth of praseodymium oxide or ruthenium oxide on ruthenium single crystal substrates, both featuring a complex distribution of coexisting surface components, varying in both chemical composition and crystallographic structure. With the factorization result a sparse sampling method is demonstrated, reducing the measurement time by 1-2 orders of magnitude, relevant for dynamic surface studies. The FSC3 concentrations are providing the features for a support vector machine (SVM) based supervised classification of the types. Here, specific surface regions which have been identified structurally, via their diffraction pattern, as well as chemically by complementary spectro-microscopic techniques, are used as training sets. A reliable classification is demonstrated on both exemplary LEEM I-V datasets.

description: We present a method of forming and controlling large arrays of gate-defined quantum devices. The method uses a novel, on-chip, multiplexed charge-locking system and helps to overcome the restraints imposed by the number of wires available in cryostat measurement systems. Two device innovations are introduced. Firstly, a multiplexer design which utilises split gates to allow the multiplexer to divide three or more ways at each branch. Secondly we describe a device architecture that utilises a multiplexer-type scheme to lock charge onto gate electrodes. The design allows access to and control of gates whose total number exceeds that of the available electrical contacts and enables the formation, modulation and measurement of large arrays of quantum devices. We fabricate devices utilising these innovations on n-type GaAs/AlGaAs substrates and investigate the stability of the charge locked on to the gates. Proof-of-concept is shown by measurement of the Coulomb blockade peaks of a single quantum dot formed by a floating gate in the device. The floating gate is seen to drift by approximately one Coulomb oscillation per hour.

description: В статье приведен реферативный обзор основных выступлений участников международной научно-практической конференции «Тенденции частноправового и публично-правового взаимодействия», прошедшей 18-19 ноября 2022 года в Северо-Западном филиале Российского государственного университета правосудия. Отмечено, что сочетание частноправового и публично-правового регулирования как в сфере частных, так и в сфере публичных отношений представляет собой закономерный процесс правового развития. Всеми докладчиками безусловно признавалось существование частноправового и публично-правового взаимодействия и отмечалась необходимость законодательного закрепления следующих тенденций этого взаимодействия: поиск эффективных правовых средств, направленных на последовательное законодательное закрепление полноты существенных условий финансовых обязательств в целях обеспечения их надлежащего исполнения; поиск и законодательное закрепление альтернативных способов урегулирования споров, в том числе с последующим учреждением системы специальных судов; в целях обеспечения баланса интересов общества и государства необходимость наделения нотариуса отдельными дополнительными правомочиями, а также ограничения объема его ответственности до предоставления ему необходимых условий осуществления профессиональной деятельности (создание адекватной информационной и технической поддержки); сокращение числа коллизионных норм социальных отраслей, являющихся препятствием для реализации государством социальной функции и демографической политики.

description: We provide a complete theoretical interpretation of the metallic broken spin/valley symmetry states recently discovered in ABC trilayer graphene (ABC) perturbed by a large transverse displacement field. Our conclusions combine insights from ABC trilayer graphene electronic structure models and mean field theory, and are guided by precise magneto-oscillation Fermi-surface-area measurements. We conclude that the physics of ABC trilayer graphene is shaped by the principle of momentum-space condensation, which favors Fermi surface reconstructions enabled by broken spin/valley flavor symmetries when the single-particle bands imply thin annular Fermi seas. We find one large outer Fermi surface enclosed majority-flavor states and one or more small inner hole-like Fermi surfaces enclosed minority-flavor states that are primarily responsible for nematic order. The smaller surfaces can rotate along a ring of van-Hove singularities or reconstruct into multiple Fermi surfaces with little cost in energy. We propose that the latter property is responsible for the quantum oscillation frequency fractionalization seen experimentally in some regions of the carrier-density/displacement-field phase diagram.
