description: The Triassic-Jurassic stratigraphy in the Yanshan fold-thrust belt is dominated by nonmarine deposits, and the division of this stratigraphy remains controversial among geologists. Age results from biostratigraphic and isotope chronological studies are inconsistent, especially for the Dengzhangzi and Guojiadian Basins in the eastern part of the Yanshan belt. We present four new detrital zircon U–Pb isotope datasets for the Triassic-Jurassic stratigraphic units and one for the Permian unit in the basins. The geochronological results show that the andesitic breccia in the Permian strata was deposited at ca. 273.78 ± 1.68 Ma, the Laohugou Formation was deposited in the Anisian-Ladinian Stage, the andesitic lava in the Shuiquangou Formation erupted at ca. 238.56 ± 0.91 Ma, and the conglomerate in the Guojiadian Formation was deposited from ca. 170 ± 5 to 163.0 ± 2.2 Ma. Field observations and facies analyses demonstrate that the Laohugou, Shuiquangou and Dengzhangzi Formations predominantly consist of subaqueous debris flow deposits, subaerial fluvial deposits, and fan delta deposits while the Guojiadian Formation is generally composed of fluvial and subaerial mass-flow deposits that formed in braided channels. Here, we propose a more precise and comprehensive Triassic-Jurassic stratigraphic division scheme based on age constraints and facies analysis. With this new stratigraphic sequence, we compare the Mesozoic stratigraphic units in the study area with those in other basins in the Yanshan fold-thrust belt in terms of the lithological associations, regional unconformities and zircon U-Pb dating results. This comparison indicates that the Indosinian and Yanshanian movements exerted a far-reaching influence on the development and evolution of the Dengzhangzi and Guojiadian Basins in the study area, forming several important regional unconformities and syntectonic conglomeratic units. These new age data on the stratigraphy are of fundamental significance for understanding the Mesozoic tectonic evolution of Yanshan.

description: Title  Investigation of Factors Affecting Efficient Information Management of Celiac Patients in the Context of Virtual Organizations
 Abstract  The study includes an infrastructure study that will propose a knowledge management model that will help patients and their relatives who have been diagnosed with celiac disease to reach accurate and reliable information quickly and efficiently and reduce the disease fighting process as much as possible. In this study , which has two research questions; the reasons for not establishing communication with new celiac patients in the province, the reasons for the process not to acceptance of these patients, and the contribution of celiac associations to this process were investigated. The findings of the study were obtained by qualitative analysis of data obtained on the basis of interviews with the managers of 16 celiac associations operating in Turkey. It was seen that celiac disease patients were more affected than social factors in terms of communication, and the most environmental factor was the contact even when they did not accept the celiac disease process. It can be said that the favorable contribution to the processes of the patients who have been diagnosed with celiac disease all over the world. At the same time, virtual organization, external environment and patients can be brought together to find that the patient adapts faster to the process.

Gauge Invariances in the Proca model

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

description: We show that the abelian Proca model, which is gauge non-invariant with second class constraints can be converted into gauge theories with first class constraints. The method used, which we call Gauge Unfixing employs a projection operator defined in the original phase space. This operator can be constructed in more than one way, and so we get more than one gauge theory. Two such gauge theories are the Stuckelberg theory, and the theory of Maxwell field interacting with an antisymmetric tensor field. We also show that the application of the projection operator does not affect the Lorentz invariance of this model.

description: We prove $\ell^{p}L^{p}$ decoupling inequalities for a class of moment manifolds. These inequalities imply optimal mean value estimates for multidimensional Weyl sums of the kind considered by Arkhipov, Chubarikov, and Karatsuba and by Parsell. In our proofs we take a new point of view on the Bourgain--Demeter--Guth induction on scales argument. This point of view substantially simplifies even the proof of $\ell^{2}L^{p}$ decoupling for the moment curve.

description: This study was focused on in vitro cytotoxicity screening of the raspberry seeds methanol extract towards a number of cancer cell lines of human origin. The tested extract at the preferred concentrations (IC50 <30 µg/mL) inhibited only the growth of the lung cancer A-549 cells (IC50 = 14.07 ± 0.96 µg/mL). At the same time, it was practically inactive (IC50 >300 µg/mL) and non-mutagenic towards normal MRC-5 lung cells. Finally, the extract potently scavenged both OH· (IC50 = 20.11 ± 1.77 µg/mL) and O2-· (IC50 = 47.23 ± 3.82 µg/mL), the free radicals of proved relevance for cancer pathophysiology. Though seeds were enriched with phenolic compounds (TPC = 5.21 ± 0.07 mg GAE/g), anthocyanins were present in traces only (TAC = 0.07 ± 0.003 mg cyn-3-glu/g), while flavonoids were not detected at all. This is the first report on anti-lung cancer potential of the seeds of any soft fruit.

description: We report the observation of local superconductivity induced at the point contact formed between a normal metal tip and WC -- a triple point topological semimetal with super hardness. Remarkably, the maximum critical temperature is up to near 12 K but insensitive to the tip's magnetism. The lateral dimensions of the superconducting puddles were evaluated and the temperature dependencies of superconducting gap and upper critical field were also obtained. These results put constraints on the explanation of the induced superconductivity and pave a pathway for exploring topological superconductivity.

description: The volatile chemicals in the leaves of six Garcinia species viz; G. assamica, G. dulcis, G. lanceifolia, G. morella var. mucrona, G. pedunculata and G. xanthochymus, collected from North East India, were studied for the first time. The essential oils obtained by hydrodistillation were analyzed by GC-FID and GC-MS, and 64 volatile components were identified. Sesquiterpene hydrocarbons predominated in all the species, and the major compounds were (E)-caryophyllene, α-copaene and β-selinene. The characteristic compound α-copaene was distinguished from its isomer α-ylangene through 13C NMR analysis. Hierarchical cluster analysis based on the volatile chemical compositions revealed that G. dulcis and G. xanthochymus are very close to each other. The compositions of North East Garcinia species were compared with that of the Western Ghats species.

description: SiO2@GdPO4:Tb@SiO2 nanoparticles with core-shell-shell structure were successfully synthesized by a cheap silane coupling agent grafting method at room temperature. This method not only homogeneously coated rare-earth phosphate nanoparticles on the surface of silica spheres but also saved the use of rare-earth resources. The obtained nanoparticles consisted of SiO2 core with a diameter of approximately 210 nm, GdPO4:Tb intermediate shell with thickness of approximately 7 nm, and SiO2 outer shell with thickness of approximately 20 nm. This unique core-shell-shell structured nanoparticles exhibited strong luminescence properties compared with GdPO4:Tb nanoparticles. The core-shell-shell structured nanoparticles can effectively quench the intrinsic fluorescence of bovine serum albumin through a static quenching mode. The as-synthesized nanoparticles show great potential in biological cell imaging and cancer treatment.
On the impacts of urban areas on heavy rainfall from North Atlantic tropical cyclones

description: Tropical cyclones (TCs) are one of the most destructive natural disasters in the world, causing significant economic damage and numerous fatalities. The United States, particularly the areas along the Gulf Coast, Florida, and the eastern seaboard, have been significantly impacted by these storms over the years; this is particularly true in highly developed urban areas on the coast and near-coastal regions. Since 1980, there have been 66 billion-dollar TC events in the United States, which caused almost 7,200 fatalities. Despite these societal and economic implications, the relationship between urbanization and TC rainfall has received limited attention in the literature. While few studies have examined the role of anthropogenic forcing in extreme rainfall related to TCs making landfall over highly populated urban areas, much less is known about the role played by the cities in modifying the heavy rainfall associated with these storms. There is also limited understanding of what physical mechanisms are responsible for these changes. To address these research gaps, this dissertation employs three studies in different urban settings and focuses on many TCs with different rainfall intensities.
description: To fill this research gap, I perform several numerical simulations using the Weather Research and Forecasting (WRF) model across different urban settings. I first start to focus on Charlotte, North Carolina, a near-coastal city, and I analyze five different storms. I then simulate two sets of wet and dry storms over the coastal city of New Orleans, Louisiana. Finally, the third study investigates both the combined and individual impact of three urban clusters in the northeastern United States (New York-New Jersey, Philadelphia, and Washington DC-Baltimore) on TC-induced rainfall for two major hurricanes (Hurricanes Irene and Ida).
description: Overall, all three analyses suggest that urban areas increase TC-induced rainfall. However, the level of impact varies based on the intensity of the storm, its landfalling direction with respect to the city, and the city’s geographic location. Charlotte has a higher impact on the wettest storms I considered, with a much more muted signal for the drier ones. The coastal city of New Orleans has a higher effect on TC-induced rainfall compared to Charlotte. Part of the reason is that the city is more coastal, and TCs over the city have high rainfall intensity; this is true for even the drier storms I analyzed. Finally, in the case of multiple urban clusters, rainfall modification is much higher in the case of a city embedded and surrounded by other cities. The results of this dissertation will be beneficial for urban planning and disaster risk management authorities to better prepare for a climate-resilient future.
Spectral and transport properties of doped Mott-Hubbard systems with incommensurate magnetic order

description: We present spectral and optical properties of the Hubbard model on a two-dimensional square lattice using a generalization of dynamical mean-field theory to magnetic states in finite dimension. The self-energy includes the effect of spin fluctuations and screening of the Coulomb interaction due to particle-particle scattering. At half-filling the quasiparticles reduce the width of the Mott-Hubbard `gap' and have dispersions and spectral weights that agree remarkably well with quantum Monte Carlo and exact diagonalization calculations. Away from half-filling we consider incommensurate magnetic order with a varying local spin direction, and derive the photoemission and optical spectra. The incommensurate magnetic order leads to a pseudogap which opens at the Fermi energy and coexists with a large Mott-Hubbard gap. The quasiparticle states survive in the doped systems, but their dispersion is modified with the doping and a rigid band picture does not apply. Spectral weight in the optical conductivity is transferred to lower energies and the Drude weight increases linearly with increasing doping. We show that incommensurate magnetic order leads also to mid-gap states in the optical spectra and to decreased scattering rates in the transport processes, in qualitative agreement with the experimental observations in doped systems. The gradual disappearence of the spiral magnetic order and the vanishing pseudogap with increasing temperature is found to be responsible for the linear resistivity. We discuss the possible reasons why these results may only partially explain the features observed in the optical spectra of high temperature superconductors.

description: Employing a combination of a sign-free Monte Carlo approach and nonequilibrium Green's function techniques, we study nonequilibrium charge transport in a model heterostructure, where a two-dimensional spin-less Falicov-Kimball system is coupled to two noninteracting leads. We show that the transport characteristic depends sensitively on the electrostatic potential in the system and exhibits different properties for different phases of the Falicov-Kimball model. In particular, pronounced step-like changes of the current and transmission are observed at the phase boundaries, evident even on a logarithmic scale. Analyzing finite size effects, we find that with the method used a relatively small system can be utilized to address specific thermodynamic limits.

description: Problems with topological uncertainties appear in many fields ranging from nano-device engineering to the design of bridges. In many of such problems, a part of the domains boundaries is subjected to random perturbations making inefficient conventional schemes that rely on discretization of the whole domain. In this paper, we study elliptic PDEs in domains with boundaries comprised of a deterministic part and random apertures, and apply the method of modified potentials with Green's kernels defined on the deterministic part of the domain. This approach allows to reduce the dimension of the original differential problem by reformulating it as a boundary integral equation posed on the random apertures only. The multilevel Monte Carlo method is then applied to this modified integral equation and its optimal $ε^{-2}$ asymptotical complexity is shown. Finally, we provide the qualitative analysis of the proposed technique and support it with numerical results.

description: The branch points of individual thermal self-energy diagrams at $k^{2}=4m^{2}, k^{2}=9m^{2},...$ are shown not to be branch points of the full thermal self-energy. Branch points of the full theory are determined by the complex, temperature-dependent energies of the quasiparticles, defined as the pole location, $k_{0}={\cal E}(\vec{k})$, of the exact retarded propagator. The full retarded self-energy is found to have branch points at $k_{0}=2{\cal E}(\vec{k}/2)$ and $k_{0}=3{\cal E}(\vec{k}/3)$ as well as cuts in the space-like region. The discontinuities across the branch cuts are complex. The advanced self-energy is related by reflection to the retarded.

Their structures were determined on the basis of extensive spectroscopic methods, including 1D-, 2D-NMR, and MS data. All the isolated compounds were evaluated for their cytotoxic activities against four human cancer cell lines including KB, MCF-7, HepG-2, and LU. As a result, compound 6 significantly exhibited cytotoxic activity against all tested human cancer cell lines with IC50 values ranging from 4.7 to 11.0 μM. Compounds 2, 5, and 7 showed moderate cytotoxic activity with IC50 values ranging from 7.0 to 38.7 μM.

description: We report here the signature of bi-modal fission, one asymmetric and the other symmetric, in Uranium nuclei in the mass range A = 230 to 236. The finding is unexpected and striking and is based on a model independent analysis of experimental mass distributions (cumulative yields) at various excitations from about 23 to 66 MeV in the alpha induced fission of 232Th. It has been found that the observed asymmetry in the mass distributions and the unusually narrow peak in the symmetry region, can both be explained in a consistent manner if one assumes: a) multi-chance fission, b) bi-modal fission at lower excitations (9 < E* < 25 MeV) for all the Uranium nuclei in the range A = 230 to 236, and c) that the shell effects get washed out completely beyond about 25 MeV of excitation resulting in symmetric fission. The analysis has allowed a quantitative estimation of the percentages of the asymmetric and the symmetric component in the bi-modal fission. It has been found that the bi-modal fission in Uranium nuclei is predominantly asymmetric (~ 85%), which contributes in a major way to the observed asymmetric peaks, while the ~15% bi-modal symmetric fission is primarily responsible for the observed narrow symmetric peak in the mass distributions. The unusually narrow symmetry peak in the mass distributions indicates that the symmetric bi-modal fission in Uranium nuclei must have proceeded from a configuration at the bi-modal symmetric saddle that is highly deformed with a well-developed neck.

description: Title  Use of Deep Learning Methods in Cyber Security
Abstract  While the cyber world has been a part of our life, it can be the target in the evil people who are born from the value of the information that circulates in this environment. In this respect, Cyber Security studies have evolved to solve problems requiring large and complicated operations due to the speed of data transmission and the development of technological infrastructures. Deep Learning methods have given a great viewpoint to the problems that should be used in learning methods such as classification or clustering by processing large data. With Deep Learning methods, which are now used in many areas of Siberian Security, while the other machine learning methods have lower performances, higher performance rates are obtained and quality of problem solution is improved. In this study, some deep learning methods used and the usage areas in Cyber Security are presented as a compilation study.

Non-perturbative approach to the attractive Hubbard model

description: A non-perturbative approach to the single-band attractive Hubbard model is presented in the general context of functional derivative approaches to many-body theories. As in previous work on the repulsive model, the first step is based on a local-field type ansatz, on enforcement of the Pauli principle and a number of crucial sum-rules. The Mermin-Wagner theorem in two dimensions is automatically satisfied. At this level, two-particle self-consistency has been achieved. In the second step of the approximation, an improved expression for the self-energy is obtained by using the results of the first step in an exact expression for the self-energy where the high- and low-frequency behaviors appear separately. The result is a cooperon-like formula. The required vertex corrections are included in this self-energy expression, as required by the absence of a Migdal theorem for this problem. Other approaches to the attractive Hubbard model are critically compared. Physical consequences of the present approach and agreement with Monte Carlo simulations are demonstrated in the accompanying paper (following this one).

Gribov vs BRST

description: We investigate the way in which the Gribov problem is manifested in the BRST quantization of simple quantum mechanical models by comparing models with and without a Gribov problem. We show that the hermiticity and nilpotency of the BRST charge together with the Batalin-Vilkovisky theorem yield non-trivial supplementary conditions on gauge fixing fermions. If the gauge fixing fermion satisfies the supplementary conditions, the BRST physical states form a space isomorphic to the Dirac space, and the BRST formal path integral does not suffer from the Gribov problem. The conventional gauge fixing fermion, that gives rise to the Faddeev-Popov integral, fails to satisfy the supplementary conditions due to the Gribov problem. Alternatively, enforcing the conventional gauge fixing fermion, these supplementary conditions imply restrictions on the BRST physical states for which the Batalin-Vilkovisky theorem holds. We find that these BRST physical states are not isomorphic the Dirac states. This can be interpreted as a violation of the Batalin-Vilkovisky theorem on the space of Dirac states and implies a breakdown of unitarity and a general dependence of physical quantities on the gauge condition.

description: We present TaDA Live, a concurrent separation logic for reasoning compositionally about the termination of blocking fine-grained concurrent programs. The crucial challenge is how to deal with abstract atomic blocking: that is, abstract atomic operations that have blocking behaviour arising from busy-waiting patterns as found in, for example, fine-grained spin locks. Our fundamental innovation is with the design of abstract specifications that capture this blocking behaviour as liveness assumptions on the environment. We design a logic that can reason about the termination of clients which use such operations without breaking their abstraction boundaries, and the correctness of the implementations of the operations with respect to their abstract specifications. We introduce a novel semantic model using layered subjective obligations to express liveness invariants, and a proof system that is sound with respect to the model. The subtlety of our specifications and reasoning is illustrated using several case studies.

description: Currently, most scene classification algorithms are trained and evaluated based on a single dataset. However, practical applications are not usually restricted to specific satellite platforms or datasets. Researchers generally train a model on one dataset and require the model to perform tasks with another dataset, leading to a data shift problem and performance decrease in practical applications. To address this problem, this study presents a metric-based few-shot classification method with L2-norm prototypical networks. Specifically, a carefully designed L2-norm layer was introduced into prototypical networks. The proposed L2-norm layer applies L2-norm operations to prototypes and query features to mitigate the length fluctuations caused by the data shift problem. With this layer, the L2-norm prototypical networks maintain the ability to identify novel classes and limit the effects of data discrepancies. The proposed L2-norm layer improves the classification accuracy by 0.42% to 2.41% on various public datasets. Moreover, L2-norm prototypical networks outperform other methods by 0.02% to 34.38%. Comprehensive experiments consistently demonstrate the advantages of the proposed method in tackling the data shift problem.

description: We prove that three-dimensional N=1 supersymmetric Yang-Mills-Chern-Simons theory is finite to all loops. This leaves open the possibility that different regularization methods give different finite effective actions. We show that for this model dimensional regularization and regularization by dimensional reduction yield the same effective action.

description: Noch anfangs der 1970er Jahre wurden in Zürich jährlich über 200 Säuglinge, die meisten von ihnen mit ausländischer Staatszugehörigkeit, in städtischen Säuglingsheimen untergebracht. Der Artikel fragt nach dem Zusammenhang zwischen den vergleichsweise späten Schliessungen der Heime und der prekären Situation der sogenannten «Gastarbeiterfamilien». Anhand von Archivmaterial wird mit einer intersektionalen Perspektive die von der Stadtverwaltung und dem Heimpersonal konstruierte Konfiguration der zugewanderten Arbeiterin mit Kind analysiert. Der Beitrag zeigt, dass die städtischen Säuglingsheime von der Arbeitsmigration der frühen 1970er Jahren profitierten und mit traditionellen Betreuungsstrukturen die mehrfache Diskriminierung von zugewanderten Eltern verstärkten.

description: The ambiguity involved in the definition of effective-mass Hamiltonians for nonrelativistic models is resolved using the Dirac equation. The multistep approximation is extended for relativistic cases allowing the treatment of arbitrary potential and effective-mass profiles without ordering problems. On the other hand, if the Schrodinger equation is supposed to be used, our relativistic approach demonstrate that both results are coincidents if the BenDaniel and Duke prescription for the kinetic-energy operator is implemented. Applications for semiconductor heterostructures are discussed.
