Floquet-induced superfluidity with periodically modulated interactions of two-species hardcore bosons in a one-dimensional optical lattice

We consider two species of hard-core bosons with density dependent hopping in a one-dimensional optical lattice, for which we propose experimental realizations using time-periodic driving. The quantum phase diagram for half-integer filling is determined by combining different advanced numerical simulations with analytic calculations. We find that a reduction of the density-dependent hopping induces a Mott-insulator to superfluid transition. For negative hopping a previously unknown state is found, where one species induces a gauge phase of the other species, which leads to a superfluid phase of gauge-paired particles. The corresponding experimental signatures are discussed.
Solar wind ten : proceedings of the tenth international solar wind conference, Pisa, Italy 17-21 June 2002

The Tenth Solar Wind conference describes the latest results in the physics of the outer solar atmosphere, the solar wind, and the interplanetary medium which together comprise the heliosphere. The conference brought together researchers studying the sun and its influence on the earth's space environment both from an experimental and theoretical point of view. The effect of the solar magnetic field in shaping and accelerating the solar wind throughout the solar cycle, via coronal heating and coronal mass ejections was described in unprecedented clarity and breadth, thanks to both satellite experiments and numerical modelling. The conference proceedings is of interest to researchers in space science and the geomagnetic effects of solar activity, plasma physicists and astrophysicists as well as other scientists interested in the life of our mother star.
Disseminated Intravascular Coagulation in Sepsis and Associated Factors

Background: sepsis is a life-threatening organ dysfunction caused by an excessive host immunological response to infection. The incidence of sepsis is increasing every year, and sepsis is the primary cause of mortality in intensive care units (ICUs). DIC is a coagulopathy syndrome that causes microvascular and macrovascular thrombosis and increases the risk of bleeding due to consumptive coagulopathy. The pathophysiology of DIC in sepsis is complex, and further research is required to investigate the involved mechanisms and risk factors. Method: this study is a prognostic analysis of a retrospective cohort. Samples were patients diagnosed with sepsis and admitted to Cipto Mangunkusumo National General Hospital from January 2016 to October 2022. Research subjects were followed until occurrence of DIC during sepsis or recovery from sepsis. The research subjects were selected from medical records using a consecutive total sampling approach. The inclusion criteria were patients aged ≥18 years old and diagnosed with sepsis according to qSOFA criteria with a score of 2. The exclusion criterion was an incomplete medical record. Bivariate and multivariate logistic regression analyses were performed to determine which independent variables contributed to the incidence of DIC and obtain the odds ratios (ORs). p < 0.05 was considered to indicate a statistically significant difference. Results: a total of 248 patients were included after considering the inclusion and exclusion criteria. Of these, 50 (20.2%) septic patients developed DIC. In the multivariate analysis, albumin ≤2.5 g/dL (OR: 2.363; 95% CI: 1.201–4.649), respiratory infection (OR: 2.414; 95% CI: 1.046–5.571), and antibiotic treatment ≥1 h (OR: 2.181; 95% CI: 1.014–4.689) were associated with DIC development. On the basis of the ROC curve, the area under the curve (AUC) was determined to be 0.705 with 95% CI = (0.631–0.778). Conclusion: in our study, the prevalence of DIC in septic patients was 20.2%. Low albumin, respiratory infection, and antibiotic treatment ≥1 h were found to be risk factors for development of DIC in septic patients.
An efficient neural network for low sampling computational ghost imaging based on EMNIST training

In this paper, we propose a new network to achieve low-sampling computational ghost imaging. The proposed neural network that combines ResNeXt, eHoloNet and spatial attention mechanism is efficient for object reconstruction just based on EMNIST training, which is much simpler and time-saving. The generalization of the neural network is verified with multi-slits as well as complex object. Both simulated and experimental results show that the proposed network can give an effective reconstruction at 0.7% sampling rate. The neural network in this work is of great significance to ghost imaging in a wider application scenarios, such as real-time imaging and dynamic detection of motion object.
Spin-filter effect at the interface of magnetic/non-magnetic homojunctions in Li doped ZnO nanostructures

After more than a decade of extensive research on the magnetic order triggered by lattice defects in a wide range of nominally non-magnetic materials, we report its application in a spintronic device. This device is based on a spin-filter phenomenon we discovered at the interfaces between defect-induced magnetic and non-magnetic regions, produced at the surface of a Li doped ZnO microwire by low-energy proton implantation. Positive magnetoresistance is observed at 300~K and scales with the number of interfaces introduced along the wire.
Surface-based Synthesis of 3D Maps for Outdoor Unstructured Environments

Narek Melkumyan Doctor of Philosophy The University of Sydney 28 August 2008 Surface-based Synthesis of 3D Maps for Outdoor Unstructured Environments This thesis is concerned with the theoretical and practical development of a surface-based mapping algorithm for reliable and robust localization and mapping in prior unknown and unstructured environments. A surface-based map consists of a set of compressed surfaces, processed and represented without geometrical modelling. Each surface in the surface-based map represents an object in the environment. The ability to represent the exact shapes of objects via individual surfaces during the mapping process makes the surface-based mapping algorithm valuable in a number of navigation applications, such as mapping of prior unknown indoor and outdoor unstructured environments, target tracking, path planning and collision avoidance. The ability to unify representations of the same object taken from different viewpoints into a single surface makes the algorithm capable of working in multi-robot mapping applications. A surface-based map of the environment is build incrementally by acquiring the 3D range image of the scene, extracting the objects’ surfaces from the 3D range image, aligning the set of extracted surfaces relative to the map and unifying the aligned set of surfaces with surfaces in the map. In the surface unification process the surfaces representing the same object are unified to make a single surface. The thesis introduces the following new methods which are used in the surface-based mapping algorithm: the extraction of surfaces from 3D range images based on a scanned surface continuity check; homogenization of the representation of the non-homogenously sampled surfaces; the alignment of the
Whittaker Modules for the Schr\"{o}dinger Algebra

In this paper, the property and the classification the simple Whittaker modules for the schr\"{o}dinger algebra are studied. A quasi-central element plays an important role in the study of Whittaker modules of level zero. For the Whittaker modules of nonzero level, our arguments use the Casimir element of semisimple Lie algebra $sl_2$ and the description of simple modules over conformal Galilei algebras by R. L\"{u}, V. Mazorchuk and K. Zhao.
The drug loading impact on dissolution and diffusion: a case-study with amorphous solid dispersions of nevirapine

Amorphous solid dispersions (ASDs) are a viable alternative to enhance the kinetic solubility of poorly water-soluble drugs. However, there is lack of discussion about the impact of drug loading on dissolution rate and drug diffusion across the membrane generated by supersaturation. So, it was obtained amorphous solid dispersions with nevirapine and polyvinylpyrrolidone K-30 by solvent evaporation method using different drug loadings (10%, 15% and 20% w/w). Thermal analysis, Fourier transform infrared spectroscopy and x-ray diffraction characterized the ASDs, indicating that there was a good miscibility between components which stabilized the drug in its amorphous state. The intermolecular interactions impacted on the ASDs in vitro performance, where they were evaluated to dissolution tests under different conditions and permeability studies. All amorphous systems had an increment in aqueous solubility compared to nevirapine alone, although 10% amorphous solid dispersion (SD 10) kept drug supersaturation at very high concentrations longer, preventing the drug recrystallization, having the greater drug flux on membranes and more intermolecular interactions among the components. Therefore, large quantities of the polymer are required for the stability of the amorphous drug, due to the increase in the number of intermolecular interactions.
Compatible confidence intervals for intersection union tests involving two hypotheses

: The intersection union test is a standard test in situations where the rejection of all elements of a set of k hypotheses is required. In particular, the intersection union test is known to be uniformly most powerful within a certain class of monotone level − α tests. In this article we consider the special case of k = 2. We consider the problem of deriving simultaneous conﬁdence intervals which are compatible with the associated test decisions. We apply the general partitioning principle of Finner and Strassburger (2002) to derive a general method to construct conﬁdence intervals which are compatible to a given test. Several examples of partitioning the two-dimensional parameter space are given and their characteristics are discussed in detail. The methods in this paper are illustrated by two gold standard clinical trials, where a new treatment under investigation is compared to both a placebo group and a standard therapy.
Low-Loss and Broadband Nonvolatile Phase-Change Directional Coupler Switches

An optical equivalent of the field-programmable gate array (FPGA) is of great interest to large-scale photonic integrated circuits. Previous programmable photonic devices relying on the weak, volatile thermo-optic or electro-optic effect usually suffer from a large footprint and high energy consumption. Phase change materials (PCMs) offer a promising solution due to the large nonvolatile change in the refractive index upon phase transition. However, the large optical loss in PCMs poses a serious problem. Here, by exploiting an asymmetric directional coupler design, we demonstrate nonvolatile PCM-clad silicon photonic 1 × 2 and 2 × 2 switches with a low insertion loss of ∼1 dB and a compact coupling length of ∼30 μm while maintaining a small crosstalk less than −10 dB over a bandwidth of 30 nm. The reported optical switches will function as the building blocks of the meshes in the optical FPGAs for applications such as optical interconnects, neuromorphic computing, quantum computing, and microwave photonics.
A note on the driving variable realization of behaviors

The problem of realizing a discrete-time behavior by means of a driving variable (DV) state-space representation is here afforded. An algebraic relation between kernel descriptions and driving variable representations is first derived and later used for obtaining a minimal DV realization of a given behavior. Internal properties of the behavior, in particular controllability, are related to the properties of its DV realizations. Finally, a different technique for obtaining a minimal DV realization in case of a controllable behavior is described.
Prospects for detecting dark matter with neutrino telescopes in intermediate mass black hole scenarios

Current strategies of indirect dark matter detection with neutrino telescopes are based on the search for high-energy neutrinos from the solar core or from the center of the Earth. Here, we propose a new strategy based on the detection of neutrinos from dark matter annihilations in mini-spikes around intermediate mass black holes. Neutrino fluxes, in this case, depend on the annihilation cross-section of dark matter particles, whereas solar and terrestrial fluxes are sensitive to the scattering cross-section off nucleons, a circumstance that makes the proposed search complementary to the existing ones. We discuss the prospects for detection with upcoming underwater and under-ice experiments such as ANTARES and IceCube, and show that several, up to many, sources could be detected with both experiments. A kilometer-scale telescope in the Mediterranean appears to be ideally suited for the proposed search.
New Developments in the Method of Space-Time Conservation Element and Solution Element-Applications to Two-Dimensional Time-Marching Problems

A new numerical discretization method for solving conservation laws is being developed. This new approach differs substantially in both concept and methodology from the well-established methods, i.e., finite difference, finite volume, finite element, and spectral methods. It is motivated by several important physical/numerical considerations and designed to avoid several key limitations of the above traditional methods. As a result of the above considerations, a set of key principles for the design of numerical schemes was put forth in a previous report. These principles were used to construct several numerical schemes that model a 1-D time-dependent convection-diffusion equation. These schemes were then extended to solve the time-dependent Euler and Navier-Stokes equations of a perfect gas. It was shown that the above schemes compared favorably with the traditional schemes in simplicity, generality, and accuracy. In this report, the 2-D versions of the above schemes, except the Navier-Stokes solver, are constructed using the same set of design principles. Their constructions are simplified greatly by the use of a nontraditional space-time mesh. Its use results in the simplest stencil possible, i.e., a tetrahedron in a 3-D space-time with a vertex at the upper time level and other three at the lower time level. Because of the similarity in their design, each of the present 2-D solvers virtually shares with its 1-D counterpart the same fundamental characteristics. Moreover, it is shown that the present Euler solver is capable of generating highly accurate solutions for a famous 2-D shock reflection problem. Specifically, both the incident and the reflected shocks can be resolved by a single data point without the presence of numerical oscillations near the discontinuity.
Localised Gravity in the Singular Domain Wall Background

We study singular, supersymmetric domain-wall solutions supported by the massive breathing mode scalars of, for example, sphere reductions in M-theory or string theory. The space-time on one side of such a wall is asymptotic to the Cauchy horizon of the anti-de Sitter (AdS) space-time. However, on the other side there is a naked singularity. The higher-dimensional embedding of these solutions has the novel interpretation of (sphere compactified) brane configurations in the domain ``inside the horizon region,'' with the singularity corresponding to the sphere shrinking to zero volume. The naked singularity is the source of an infinite attractive gravitational potential for the fluctuating modes. Nevertheless, the spectrum is bounded from below, continuous and positive definite, with the wave functions suppressed in the region close to the singularity. The massless bound state is formally excluded due to the boundary condition for the fluctuating mode wave functions at the naked singularity. However, a regularisation of the naked singularity, for example by effects of the order of the inverse string scale, in turn regularises the gravitational potential and allows for precisely one (massless) bound-state spin-2 fluctuating mode. We also contrast spectra in these domain wall backgrounds with those of the domain walls due to the massless modes of sphere reductions.

Multidimensional Poverty in Sudan: An Empirical Analysis for the Case of Gezira State, 2021

Poverty remains the most pressing socio-economic issue among all states in Sudan. Poverty is a multi–faceted phenomenon. This paper is set to investigate the persistence of multidimensional poverty among households of Gezira state, following the approach proposed by Alkire-Santos model made up of 10 components has been built and used as a means of analyzing the data, The education and health dimensions are based on two indicators while the standard of living dimension is based on six indicators. The research relies on primary data aided by structured questionnaire compiled by Central Bureau of Statistics staff, field work cover three localities, where around 57% of the households in the state live in these localities. A total of 756 households randomly selected make up for data source upon which the research rests, the analysis of poverty decomposed by urban and rural location. The results indicated that 15.89% of the population under the study area are experience a multidimensional poverty, with deprivation at least a third of the dimensions of health, education and standard of living, present analysis shows decompositions reveal considerable disparity in MPI, rural areas present high levels of MPI than urban one, and the deprivation seem to be concentrated in all dimensions. The standard of living dimension considered the main contributor to poverty in Janoob Al Gezira and El Hasaheisa localities, El Managil locality presents the highest incidence of the MPI due to poor health dimension. Janoob Al Gezira Locality faced severe deprivations in health of children as child mortality is widely spread among the poor population in urban area and low level of education was to be found. The paper concludes with policy implications based on the findings that will help government to identify the poor and where the poor people are live.
Intermittent character of interplanetary magnetic field fluctuations

Interplanetary magnetic field magnitude fluctuations are notoriously more intermittent than velocity fluctuations in both fast and slow wind. This behavior has been interpreted in terms of the anomalous scaling observed in passive scalars in fully developed hydrodynamic turbulence. In this paper, the strong intermittent nature of the interplanetary magnetic field is briefly discussed comparing results performed during different phases of the solar cycle. The scaling properties of the interplanetary magnetic field magnitude show solar cycle variation that can be distinguished in the scaling exponents revealed by structure functions. The scaling exponents observed around the solar maximum coincide, within the errors, to those measured for passive scalars in hydrodynamic turbulence. However, it is also found that the values are not universal in the sense that the solar cycle variation may be reflected in dependence on the structure of the velocity field.
Asteroseismology of the Hyades red giant and planet host ϵ Tauri

Context. Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most other methods. Even in a well-studied cluster such as the Hyades, the masses of the red giant stars are not well known, and previous mass estimates are based on model calculations (isochrones). The four known red giants in the Hyades are assumed to be clump (core-helium-burning) stars based on their positions in colour-magnitude diagrams, however asteroseismology offers an opportunity to test this assumption. Aims. Using asteroseismic techniques combined with other methods, we aim to derive physical parameters and the evolutionary stage for the planet hosting star ϵ Tau, which is one of the four red giants located in the Hyades. Methods. We analysed time-series data from both ground and space to perform the asteroseismic analysis. By combining high signal-to-noise radial-velocity data from the ground-based SONG network with continuous space-based data from the revised Kepler mission K2, we derive and characterize 27 individual oscillation modes for ϵ Tau, along with global oscillation parameters such as the large frequency separation Δν and the ratio between the amplitude of the oscillations measured in radial velocity and intensity as a function of frequency. The latter has been measured previously for only two stars, the Sun and Procyon. Combining the seismic analysis with interferometric and spectroscopic measurements, we derive physical parameters for ϵ Tau, and discuss its evolutionary status. Results. Along with other physical parameters, we derive an asteroseismic mass for ϵ Tau of M = 2.458 ± 0.073 M⊙, which is slightly lower than previous estimates, and which leads to a revised minimum mass of the planetary companion. Noting that the SONG and K2 data are non-simultaneous, we estimate the amplitude ratio between intensity and radial velocity to be 42.2 ± 2.3 ppm m−1 s, which is higher than expected from scaling relations.
