description: We present elemental abundance results for HE 2148-2039 and HE 2155-2043 based on a detailed high-resolution spectroscopic analysis. The high-resolution SUBARU/HDS spectra used for our analysis have a resolution of R~60 000. Although limited information based on photometry and low-resolution spectroscopy are available, we present for the first time an abundance analysis based on high-resolution spectra for both the objects. Our analysis shows that the two objects are extremely metal-poor with [Fe/H]< -3. Among the neutron-capture elements, abundances of only Sr and Ba could be determined in our programme stars. For both the objects [Ba/Fe] is found to be < 0. While strontium is under abundant in HE 2148-2039 with [Sr/Fe]~ -2.02, Sr is near solar in HE 2155-2043. The locations of the programme stars in the absolute carbon abundance, A(C) vs. [Fe/H] diagram show that HE 2148-2039 is a CEMP-no Group II object and HE 2155-2043 is a CEMP-no Group III object. Observed [Sr/Ba] ratios are characteristics of a fast rotating massive star progenitor for HE 2155-2043 and a metal-poor Asymptotic giant branch (AGB) star for HE 2148-2039. The estimated [Sc/Mn] as well as [C/Cr] ratios in HE 2155-2043 show that the surface chemical composition of this object is mono-enriched. The surface chemical composition of HE 2148-2039 is also found to be mono-enriched based on [Mg/C] ratio. With respect to their locations in the [C/N] vs. T eff diagram, HE 2148-2039 shows signatures of mixing, and HE 2155-2043 falls in the unmixed region of [C/N] vs. Teff plot. Kinematic analysis shows that both the objects belong to Galactic halo population.

description: High-throughput grain mapping with sub-nanometer spatial resolution is demonstrated using scanning nanobeam electron diffraction (also known as 4D scanning transmission electron microscopy, or 4D-STEM) combined with high-speed direct electron detection. An electron probe size down to 0.5 nm in diameter is implemented and the sample investigated is a gold-palladium nanoparticle catalyst. Computational analysis of the 4D-STEM data sets is performed using a disk registration algorithm to identify the diffraction peaks followed by feature learning to map the individual grains. Two unsupervised feature learning techniques are compared: Principal component analysis (PCA) and non-negative matrix factorization (NNMF). The characteristics of the PCA versus NNMF output are compared and the potential of the 4D-STEM approach for statistical analysis of grain orientations at high spatial resolution is discussed.

description: We have carried out an extensive X-ray spectral study of the bare Seyfert-1 galaxy MCG--02--58--22 to ascertain the nature of the X-ray reprocessing media, using observations from Suzaku (2009) and simultaneous observations from XMM-Newton and NuSTAR (2016) . The most significant results of our investigation are: 1. The primary X-ray emission from the corona is constant in these observations, both in terms of the power law slope ($Γ=1.80$) and luminosity ($L_{2-10 \rm keV}= 2.55\times 10^{44} $ erg/s). 2. The soft excess flux decreased by a factor of two in 2016, the Compton hump weakened/vanished in 2016, and the narrow FeK$α$ emission line became marginally broad ($σ=0.35\pm0.08$ keV) and its flux doubled in 2016. 3. From physical model fits we find that the normalization of the narrow component of the FeK$α$ line does not change in the two epochs, although the Compton hump vanishes in the same time span. Since the primary X-ray continuum does not change, we presume that any changes in the reprocessed emission must arise due to changes in the reprocessing media. Our primary conclusions are: A. The vanishing of the Compton hump in 2016 can probably be explained by a dynamic clumpy torus which is infalling/outflowing, or by a polar torus wind. B. The torus in this AGN possibly has two structures: an equatorial toroidal disk (producing the narrow FeK$α$ emission) and a polar component (producing the variable Compton hump), C. The reduction of the soft-excess flux by half and increase in the FeK$α$ flux by a factor of two in the same period cannot be adequately explained by ionized disk reflection model alone.

description: We demonstrate experimentally a method of varying the degree of directionality in laser-induced molecular rotation. To control the ratio between the number of clockwise and counter-clockwise rotating molecules (with respect to a fixed laboratory axis), we change the polarization ellipticity of the laser field of an optical centrifuge. The experimental data, supported by the numerical simulations, show that the degree of rotational directionality can be varied in a continuous fashion between unidirectional and bidirectional rotation. The control can be executed with no significant loss in the total number of rotating molecules. The technique could be used for studying the effects of orientation of the molecular angular momentum on molecular collisions and chemical reactions. It could also be utilized for controlling magnetic and optical properties of gases, as well as for the enantioselective detection of chiral molecules.

description: Interstate widening projects are commonplace in Kentucky, and safety is of primary concern within the project work zone. Past experience with long work zones revealed two critical safety issues: driver confusion due to unclear pavement markings and a lack of continuous work zone signage for motorists indicating they are still within a work zone. This concern is heightened in transition and taper areas. Highly visible markings in an alternative color other than standard yellow or white might better distinguish the proper travel path for motorists and prevent drivers from returning to normal driving behavior and speeds once they get through the initial transition area. To address these safety issues, the research team applied orange edge and lane lines in a work zone and studied the effects on speed, crashes, and driver behavior. Due to retroreflectivity requirements, retroreflectometer data was also collected, and researchers gathered feedback from the public and contract/construction personnel. The results of testing orange pavement markings in one work zone offer evidence that further studies should be performed, but the study was not large enough to provide conclusive evidence that orange pavement markings should be regularly employed. Retroreflectivity thresholds of the markings can be met if a high-end bead package is used. Crashes increased with the use of orange pavement markings, but there was evidence that the crashes were less severe. Specifically, wet and nighttime crashes were reduced. The speed data collected in the study indicates that very few drivers lower their speed as they travel through a work zone, even when orange pavement markings are added as a reminder. The public opinion survey revealed positive results that indicate the public would be receptive to the use of orange pavement markings in future work zones.

description: Recent advances in emergent geometry have identified a new class of models that represent spacetime as the graph obtained as the ground state of interacting Ising spins. These models have many desirable features, including stable excitations possessing many of the characteristics of a quantum particle. We analyze the dynamics of such excitations, including a detailed treatment of the edge states not previously addressed. Using a minimal prescription for the interaction of defects we numerically investigate approximate bounds to the speed of propagation of such a `particle'. We discover, using numerical simulations, that there may be a Lieb-Robinson bound to propagation that could point the way to how a causal structure could be accommodated in this class of emergent geometry models.
Constructing Squeezed States of Light with Associated Hermite Polynomials

description: A new class of states of light is introduced that is complementary to the well-known squeezed states. The construction is based on the general solution of the three-term recurrence relation that arises from the saturation of the Schrödinger inequality for the quadratures of a single-mode quantized electromagnetic field. The new squeezed states are found to be linear superpositions of the photon-number states whose coefficients are determined by the associated Hermite polynomials. These results do not seem to have been noticed before in the literature. As an example, the new class of squeezed states includes superpositions characterized by odd-photon number states only, so they represent the counterpart of the prototypical squeezed-vacuum state which consists entirely of even-photon number states.

description: A proof-of-principle electron electric dipole moment (e-EDM) experiment using slow cesium atoms, nulled magnetic fields, and electric field quantization has been performed. With the ambient magnetic fields seen by the atoms reduced to less than 200 pT, an electric field of 6 MV/m lifts the degeneracy between states of unequal mF and, along with the low (approximately 3 m/s) velocity, suppresses the systematic effect from the motional magnetic field. The low velocity and small residual magnetic field have made it possible to induce transitions between states and to perform state preparation, analysis, and detection in regions free of applied static magnetic and electric fields. This experiment demonstrates techniques that may be used to improve the e-EDM limit by two orders of magnitude, but it is not in itself a sensitive e-EDM search, mostly due to limitations of the laser system.

description: In dieser Arbeit wird die Entwicklung einer mikrofluidischen Plattform für die galvanische Abscheidung von Chitosan-Hydrogel vorgestellt. Die Plattform ist kompatibel mit einem NMR-Mikrodetektor, einer Helmholtz-NMR-Mikrospule, und war für die Bestimmung der Funktion verschiedener Enzyme in Echtzeit vorgesehen. Die experimentellen Verfahren wurden ausführlich beschrieben, einschließlich der Herstellung des mit verschiedenen Elektrodengeometrien integrierten Mikrofluidikkanals, des Protokolls für die Vorbereitung der Vor- und Nachbearbeitung von Chitosan als Substrat, der Einrichtung der Elektroabscheidung von vor- und nachbearbeitetem Chitosan unter Verwendung der verschiedenen Elektrodenkonfigurationen und des Protokolls für die NMR-Analyse zur Überwachung der Funktion verschiedener immobilisierter Enzyme. Der erste Teil der Dissertation stellt im Detail die Technologie hinter der Realisierung biofunktionaler Array-Sites mit programmierbarer Zusammensetzungskontrolle in allen drei räumlichen Dimensionen vor. Die Technologie basiert auf der sequentiellen galvanischen Abscheidung von Chitosan. Aufgrund des sequentiellen Charakters dieses Verfahrens kann jede Schicht einzeln chemisch funktionalisiert werden, während gleichzeitig eine molekulare Kommunikation zwischen den Schichten über das poröse Netzwerk im gesamten fertigen Komposit- Hydrogel ermöglicht wird. Der zweite Teil der Arbeit befasst sich mit der Integration zusätzlicher Funktionalitäten in mikrofluidische Geräte, wobei die Aufrechterhaltung qualitativ hochwertiger NMR-Spektren eine große Herausforderung darstellt. Die entwickelte NMR-Plattform besteht aus einem Fluidikkanal mit verschiedenen Konfigurationen von integrierten Elektroden, die für die in-situ-Elektrodenabscheidung von vor- und nachmodifiziertem Chitosan verwendet wurden. Schließlich wird im dritten Teil der Arbeit als Proof-of-Concept-Anwendung die Bestimmung der Funktion von immobilisierten Enzymen mit Hilfe der Elektroplattformen diskutiert. Drei Schichten Chitosan-Gel, gekoppelt an verschiedene Enzyme, wurden gestapelt; anschließend wurde die Reaktion der Enzyme mit ihren jeweiligen Substraten in Echtzeit mit NMR überwacht. Die enzymatische Aktivität wurde im Rahmen eines Michaelis-Menten-Modells analysiert. Diese Plattform demonstriert die Fähigkeit der entwickelten Plattform, NMR-Analysen von bioaktiven komplexen Molekülen in einer kleinen Massenmenge durchzuführen, was neue Möglichkeiten für Fortgeschrittene Elektrochemie- und Metabolomikstudien eröffnet.

description: Accurate predictions of charge excitation energies of molecules in the disordered condensed phase are central to the chemical reactivity, stability, and optoelectronic properties of molecules and critically depend on the specific environment. Herein, we develop a stochastic GW method for calculating these charge excitation energies. The approach employs maximally localized electronic states to define the electronic subspace of a molecule and the rest of the system, both of which are randomly sampled. We test the method on three solute-solvent systems: phenol, thymine, and phenylalanine in water. The results are in excellent agreement with the previous high-level calculations and available experimental data. The stochastic calculations for supercells representing the solvated systems are inexpensive and require $\sim 1000$ CPU$\cdot$hrs. We find that the coupling with the environment accounts for $\sim40\%$ of the total correlation energy. The solvent-to-solute feedback mechanism incorporated in the molecular correlation term causes up to 0.6 eV destabilization of the QP energy. Simulated photo-emission spectra exhibit red shifts, state-degeneracy lifting, and lifetime shortening. Our method provides an efficient approach for an accurate study of excitations of large molecules in realistic condensed phase environments.

description: UI design is an integral part of software development. For many developers who do not have much UI design experience, exposing them to a large database of real-application UI designs can help them quickly build up a realistic understanding of the design space for a software feature and get design inspirations from existing applications. However, existing keyword-based, image-similarity-based, and component-matching-based methods cannot reliably find relevant high-fidelity UI designs in a large database alike to the UI wireframe that the developers sketch, in face of the great variations in UI designs. In this article, we propose a deep-learning-based UI design search engine to fill in the gap. The key innovation of our search engine is to train a wireframe image autoencoder using a large database of real-application UI designs, without the need for labeling relevant UI designs. We implement our approach for Android UI design search, and conduct extensive experiments with artificially created relevant UI designs and human evaluation of UI design search results. Our experiments confirm the superior performance of our search engine over existing image-similarity or component-matching-based methods and demonstrate the usefulness of our search engine in real-world UI design tasks.

description: Transverse spin angular momentum of light is a key concept in recent nanophotonics to realize unidirectional light transport in waveguides by spin-momentum locking. Herein we theoretically propose subwavelength nanoparticle chain waveguides that efficiently sort optical spins with engineerable spin density distributions. By arranging high-refractive-index nanospheres of different sizes in a zigzag manner, directional optical spin propagation is realized. The origin of the efficient spin transport is revealed by analyzing the dispersion relation and spin angular momentum density distributions. In contrast to conventional waveguides, the proposed asymmetric waveguide can spatially separate up- and down-spins and locate one parity inside and the other outside the structure. Moreover, robustness against bending the waveguide and its application as an optical spin sorter are presented. Compared to previous reports on spatial engineering of local spins in photonic crystal waveguides, we achieved substantial miniaturization of the entire footprint down to subwavelength scale.

description: CSI (Channel State Information) of WiFi systems contains the environment channel response between the transmitter and the receiver, so the people/objects and their movement in between can be sensed. To get CSI, the receiver performs channel estimation based on the pre-known training field of the transmitted WiFi signal. CSI related technology is useful in many cases, but it also brings concerns on privacy and security. In this paper, we open sourced a CSI fuzzer to enhance the privacy and security of WiFi CSI applications. It is built and embedded into the transmitter of openwifi, which is an open source full-stack WiFi chip design, to prevent unauthorized sensing without sacrificing the WiFi link performance. The CSI fuzzer imposes an artificial channel response to the signal before it is transmitted, so the CSI seen by the receiver will indicate the actual channel response combined with the artificial response. Only the authorized receiver, that knows the artificial response, can calculate the actual channel response and perform the CSI sensing. Another potential application of the CSI fuzzer is covert channels based on a set of pre-defined artificial response patterns. Our work resolves the pain point of implementing the anti-sensing idea based on the commercial off-the-shelf WiFi devices.

description: Supervised learning with deep convolutional neural networks (DCNNs) has seen huge adoption in stereo matching. However, the acquisition of large-scale datasets with well-labeled ground truth is cumbersome and labor-intensive, making supervised learning-based approaches often hard to implement in practice. To overcome this drawback, we propose a robust and effective self-supervised stereo matching approach, consisting of a pyramid voting module (PVM) and a novel DCNN architecture, referred to as OptStereo. Specifically, our OptStereo first builds multi-scale cost volumes, and then adopts a recurrent unit to iteratively update disparity estimations at high resolution; while our PVM can generate reliable semi-dense disparity images, which can be employed to supervise OptStereo training. Furthermore, we publish the HKUST-Drive dataset, a large-scale synthetic stereo dataset, collected under different illumination and weather conditions for research purposes. Extensive experimental results demonstrate the effectiveness and efficiency of our self-supervised stereo matching approach on the KITTI Stereo benchmarks and our HKUST-Drive dataset. PVStereo, our best-performing implementation, greatly outperforms all other state-of-the-art self-supervised stereo matching approaches. Our project page is available at sites.google.com/view/pvstereo.

title: The masks of anarchy : a theoretical study of the intersections between punk and alternative comedy
Creators: name: Bonello Rutter Giappone, Krista
Publisher: name: University of Kent
Year: 2021

description: Punk's place within pop-cultural history is assured, yet in the claims made for its 'serious' and revolutionary role, the part played by the comic in its critical function remains relatively under-explored. This thesis aims to investigate this dimension in greater depth, pursuing the intersections further into punk's own influence on the subsequent growth of alternative comedy. As with any movement that emphasises 'newness' and change, punk and alternative comedy defined themselves against a ' past' and a 'dominant'. The cultural context and their [disengagement [from]with it will be explored through a theoretical analysis which takes in both the parodic aspect, and punk's attempted reconfiguration of the very terms of ' history' and relation to context - space, time, memory, past, future. Punk will be considered as both a 'post modem' phenomenon, and as mounting a challenge to postmodernism. One major area of change, touching upon shifting boundaries of power in performance, is that of the performer-audience dynamic. The techniques available to alternative comedians will be seen to be indebted to the altered dynamic enabled by punk. The deconstruction of hierarchies will be discussed in tandem with the continued struggle for dominance. The interplay of alienation and engagement, violence and play, along with the invocation of the abject, will be considered in relation to comic theory. Notions of honesty in performance emerge throughout as particularly crucial in both punk and alternative comedy's self-construction, and the implications of this for identity and onstage personae will be examined. The move from 'truth of performance' to 'performative fiction' will he considered in relation to attempted contextual reconfigurations, with the entailed question of the 'amateur's' incomplete abdication of responsibility. I will suggest that alternative comedy makes an effort to redress punk's lapses on this point, and thence to restore a sense of political responsibility.

description: While the accuracy of 3D human pose estimation from images has steadily improved on benchmark datasets, the best methods still fail in many real-world scenarios. This suggests that there is a domain gap between current datasets and common scenes containing people. To obtain ground-truth 3D pose, current datasets limit the complexity of clothing, environmental conditions, number of subjects, and occlusion. Moreover, current datasets evaluate sparse 3D joint locations corresponding to the major joints of the body, ignoring the hand pose and the face shape. To evaluate the current state-of-the-art methods on more challenging images, and to drive the field to address new problems, we introduce AGORA, a synthetic dataset with high realism and highly accurate ground truth. Here we use 4240 commercially-available, high-quality, textured human scans in diverse poses and natural clothing; this includes 257 scans of children. We create reference 3D poses and body shapes by fitting the SMPL-X body model (with face and hands) to the 3D scans, taking into account clothing. We create around 14K training and 3K test images by rendering between 5 and 15 people per image using either image-based lighting or rendered 3D environments, taking care to make the images physically plausible and photoreal. In total, AGORA consists of 173K individual person crops. We evaluate existing state-of-the-art methods for 3D human pose estimation on this dataset and find that most methods perform poorly on images of children. Hence, we extend the SMPL-X model to better capture the shape of children. Additionally, we fine-tune methods on AGORA and show improved performance on both AGORA and 3DPW, confirming the realism of the dataset. We provide all the registered 3D reference training data, rendered images, and a web-based evaluation site at https://agora.is.tue.mpg.de/.

description: Most quantum states have wavefunctions that are widely spread over the accessible Hilbert space and hence do not have a good description in terms of a single classical geometry. In order to understand when geometric descriptions are possible, we exploit the AdS/CFT correspondence in the half-BPS sector of asymptotically AdS_5 x S^5 universes. In this sector we devise a "coarse-grained metric operator" whose eigenstates are well described by a single spacetime topology and geometry. We show that such half-BPS universes have a non-vanishing entropy if and only if the metric is singular, and that the entropy arises from coarse-graining the geometry. Finally, we use our entropy formula to find the most entropic spacetimes with fixed asymptotic moments beyond the global charges.

description: Sr$_2$CuO$_2$Cl$_2$ (SCOC) is a model undoped cuprate with $I4/mmm$ crystallographic symmetry, and a simple magnetic space group $C_Amca$ with associated magnetic point group $mmm1'$. However, recent second harmonic spectroscopy in the antiferromagnetic phase has challenged this picture, suggesting instead a magnetic point group $4/mm'm'$ that co-exists with the antiferromagnetism and breaks the two orthogonal mirror planes containing the tetragonal $c$-axis. Here, we analyze the symmetry of SCOC in light of the second harmonic results, and discuss possible ground states that are consistent with the data.
Semantic memory in Alzheimer's Disease

description: Alzheimer's Disease is characterized by a general decline in cognitive functioning. Although phonology are relatively unaffected, patients with Alzheimer's Disease have been reported to have deficits of semantic memory. Thirteen patients with dementia, five of whom had a confirmed diagnosis of dementia, participated in the study. The purpose of this investigation was to replicate a study performed by Mark Byrd (1984), using Alzheimer's Disease patients. Subjects were presented with category-word decision pairs, for which the task was to decide if the word was an exemplar of the category, and category-letter decision pairs for which the task was to generate an exemplar of the category beginning with the letter. The dependent variable was reaction time. Results indicated that Alzheimer's Disease patients and dementia patients had longer reaction times than a group of age-matched control subjects, and that the Alzheimer's Disease and dementia patients showed a pattern of responses similar to that of the control subjects. All groups showed longer reaction times for the generation trials than the decision trials. The results are consistent with the existence of a semantic memory deficit in Alzheimer's Disease, but other interpretations were discussed.

description: The association between three AQP4 gene SNPs (rs2075575, rs162009, rs335929) and Parkinson’s disease (PD) in an Italian cohort was investigated. Results show no significant correlation between these SNPs and PD risk. However, rs162009 was linked to reduced risk of REM sleep behavior disorder (RBD) in PD patients. Additionally, rs2075575 was associated with hallucinations in PD. These findings highlight the potential role of AQP4 in sleep disorders and PD symptoms, warranting further research.

description: The strain glassy phase is produced by doping a small percentage of impurity in a martensitic alloy. Its ground state is conceived to consist of martensitic nano domains spatially separated from each other by a defect phase. The present study, by probing the local structure around the Ni and Ti in martensitic and strain glassy compositions of Ni$_{50+x}$Ti$_{50-x}$, for the first time, identifies the defect phase that is responsible for inhibiting the long range ordering of the elastic strain vector leading to the formation of the strain glassy phase.

On the existence of supergravity duals to D1--D5 CFT states

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We define a metric operator in the 1/2-BPS sector of the D1-D5 CFT, the eigenstates of which have a good semi-classical supergravity dual; the non-eigenstates cannot be mapped to semi-classical gravity duals. We also analyse how the data defining a CFT state manifests itself in the gravity side, and show that it is arranged into a set of multipoles. Interestingly, we find that quantum mechanical interference in the CFT can have observable manifestations in the semi-classical gravity dual. We also point out that the multipoles associated to the normal statistical ensemble fluctuate wildly, indicating that the mixed thermal state should not be associated to a semi-classical geometry.

description: We propose a new architecture for implementing electronic interferometry in quantum Hall bars. It exploits scattering among parallel edge channels. In contrast to previous developments, this one employs a simply-connected mesa admitting serial concatenation of building elements closer to optical analogues. Implementations of Mach-Zehnder and Hambury-Brown-Twiss interferometers are discussed together with new structures yet unexplored in quantum electronics.

Accretion onto black holes and relativistic jets

description: Relativistic jets from Active Galactic Nuclei are known since decades, but the study of the connection between accretion and ejection in these systems is hampered by the long time scales associated to these events. The past decade has seen a rapid advancement due to the observation of similar radio jets in galactic X-ray binaries, where the time scales are much shorter. A clear connection between accretion and ejection has been found for these systems, together with a solid characterization of the phenomenological properties of their outbursts. This wealth of new results has led to a detailed comparison between X-ray binaries and AGN, from which a number of correlations and scaling laws has been established. Here I briefly review the current observational status.

description: We consider the problem of discriminating between two different states of a finite quantum system in the setting of large numbers of copies, and find a closed form expression for the asymptotic exponential rate at which the specified error probability tends to zero. This leads to the identification of the quantum generalisation of the classical Chernoff distance. The proof relies on two new techniques that have been introduced in [quant-ph/0610027] and [quant-ph/0607216], respectively, and that are also well suited to prove the quantum generalisation of the Hoeffding bound, which is a modification of the Chernoff distance and specifies the optimal achievable asymptotic error rate in the context of asymmetric hypothesis testing. This has been done subsequently by Hayashi [quant-ph/0611013] and Nagaoka [quant-ph/0611289] for the special case where both hypotheses have full support. Moreover, quantum Stein's Lemma and quantum Sanov's theorem may be derived directly from the quantum Hoeffding bound combining it with a result obtained recently in [math/0703772]. The goal of this paper is to present the proofs of the above mentioned results in a unified way and in full generality (allowing hypothetic states with different supports). Additionally, we give an in-depth treatment of the properties of the quantum Chernoff distance. We argue that, although it is not a metric, it is a natural distance measure on the set of density operators, due to its clear operational meaning.

description: The two-band Hubbard model is used to analyze a possibility of a non-uniform charge distribution in a strongly correlated electron system with two types of charge carriers. It is demonstrated that in the limit of strong on-site Coulomb repulsion, such a system has a tendency to phase separation into the regions with different charge densities even in the absence of magnetic or any other ordering. This tendency is especially pronounced if the ratio of the bandwidths is large enough. The characteristic size of inhomogeneities is estimated accounting for the surface energy and the electrostatic energy related to the charge imbalance.

description: We present semi-streaming algorithms for basic graph problems that have optimal per-edge processing times and therefore surpass all previous semi-streaming algorithms for these tasks. The semi-streaming model, which is appropriate when dealing with massive graphs, forbids random access to the input and restricts the memory to O(n*polylog n) bits. Particularly, the formerly best per-edge processing times for finding the connected components and a bipartition are O(alpha(n)), for determining k-vertex and k-edge connectivity O(k^2n) and O(n*log n) respectively for any constant k and for computing a minimum spanning forest O(log n). All these time bounds we reduce to O(1). Every presented algorithm determines a solution asymptotically as fast as the best corresponding algorithm up to date in the classical RAM model, which therefore cannot convert the advantage of unlimited memory and random access into superior computing times for these problems.

description: Objectives: Christmas holidays have been associated with the highest incidence of myocardial infarction (MI). We wanted to assess possible triggers of MI during Christmas. Design: A nationwide, retrospective postal survey with case-control design. All individuals suffering an MI during the Christmas holidays 2018 and 2019 in Sweden were identified through the SWEDEHEART registry and a control group matched in age and gender with chronic coronary syndrome who did not seek medical attention during Christmas were asked for participation. Subjects completed a questionnaire asking them to rate 27 potential MI-triggers as having occurred more or less than usual. Results: A total of 189 patients suffering an MI on Christmas Eve, Christmas Day, or Boxing Day, and 157 patients in the control group responded to the questionnaire, representing response rates of 66% and 62%, respectively. Patients with MI on Christmas experienced more stress (37% vs. 21%, p = .002), depression (21% vs. 11%, p = .024), and worry (26% vs. 10%, p p = .002 and 32% vs. 43%, p = .031). There were no increases in quarrels, anger, economic worries, or reduced compliance with medication. Conclusions: Patients suffering MI on Christmas holiday experienced higher levels of stress and emotional distress compared to patients with chronic coronary syndrome, possibly contributing to the phenomenon of holiday heart attack. Understanding what factors increase the number of MI on Christmas may help reduce the excess number of MIs and cardiovascular burden.
Phenomenology of the Hidden SU(2) Vector Dark Matter Model

description: We investigate the phenomenology of an extension of the Standard Model (SM) by a non-abelian gauge group $SU(2)_{HS}$ where all SM particles are singlets under this gauge group, and a new scalar representation $ϕ$ that is singlet under SM gauge group and doublet under $SU(2)_{HS}$. In this model, the dark matter (DM) candidates are the three mass degenerate dark photons $A_{i}$ $(i=1,2,3)$ of $SU(2)_{HS}$; and the hidden sector interacts with the (SM) particles through the Higgs portal interactions. Consequently, there will be a new CP-even scalar $η$ that could be either heavier or lighter than the SM-like Higgs. By taking into account all theoretical and experimental constraints such as perturbativity, unitarity, vacuum stability, non-SM Higgs decays, DM direct detection, DM relic density, we found viable DM is possible in the range from GeV to TeV. Within the viable parameters space, the both of the triple Higgs coupling and the di-Higgs production at LHC14 could be enhanced or reduced depending on the scalar mixing and the mass of the scalar particle $η$.
