description: The s-wave isoscalar amplitude for pion-pion scattering in a nuclear medium is evaluated using a nonperturbative unitary coupled channels method and the standard chiral Lagrangians. The method has proved successful to describe the pion-pion properties in the scalar isoscalar channel up to 1.2 GeV giving rise to poles in the t matrix for the f0(980) and the sigma. The extension of the method to the nuclear medium implies not only the renormalization of the pions in the medium, but also the introduction of interaction terms related to contact terms in the pion-nucleon to pion-pion-nucleon interaction. Off shell effects are also shown to be important leading to cancellations which reduce the coupled channel integral equations to a set of algebraic equations. As the density increases we find a reduction of strength below the $σ$ region and a certain accumulation of strength at energies around pion threshold. Our results, based on chiral Lagrangians, provide similar results to those obtained with phenomenological models which impose minimal chiral constraints.

description: Magnetization curve and changes of the single-particle excitation spectra by magnetic field are calculated for the periodic Anderson model at half-filling in infinite spatial dimension by using the exact diagonalization method. It is found that the field-induced insulator-to-metal transition occurs at a critical field $H_c$, which is of the order of the single ion Kondo temperature. The transition is of first order, but could be of second order in the infinite system size limit. These results are compared with the experiments on the Kondo insulator YbB$_{12}$.

description: We investigate the three-dimensional electronic structure of the seminal charge-density-wave (CDW) material 2H-NbSe$_2$ by soft x-ray angle-resolved photoelectron spectroscopy and density-functional theory. Our results reveal the pronounced 3D character of the electronic structure formed in the quasi-two-dimensional layered crystal structure. In particular, we find a strong dispersion along $k_z$ excluding a nesting-driven CDW formation based on experimental data. The 3D-like band structure of 2H-NbSe$_2$ has strong implications for the intriguing phase competition of CDW order with superconductivity.

description: Glioblastoma Multiforme is a high grade, very aggressive, brain tumor, with patients having a poor prognosis. Lower grade gliomas are less aggressive, but they can evolve into higher grade tumors over time. Patient management and treatment can vary considerably with tumor grade, ranging from tumor resection followed by a combined radio- and chemotherapy to a "wait and see" approach. Hence, tumor grading is important for adequate treatment planning and monitoring. The gold standard for tumor grading relies on histopathological diagnosis of biopsy specimens. However, this procedure is invasive, time consuming, and prone to sampling error. Given these disadvantages, automatic tumor grading from widely used MRI protocols would be clinically important, as a way to expedite treatment planning and assessment of tumor evolution. In this paper, we propose to use Convolutional Neural Networks for predicting tumor grade directly from imaging data. In this way, we overcome the need for expert annotations of regions of interest. We evaluate two prediction approaches: from the whole brain, and from an automatically defined tumor region. Finally, we employ interpretability methodologies as a quality assurance stage to check if the method is using image regions indicative of tumor grade for classification.

description: We present detailed multi-wavelength observations of GRB 161219B at $z=0.1475$, spanning the radio to X-ray regimes, and the first ALMA light curve of a GRB afterglow. The cm- and mm-band observations before $8.5$ d require emission in excess of that produced by the afterglow forward shock (FS). These data are consistent with radiation from a refreshed reverse shock (RS) produced by the injection of energy into the FS, signatures of which are also present in the X-ray and optical light curves. We infer a constant-density circumburst environment with an extremely low density, $n_0\approx 3\times10^{-4}$ cm$^{-3}$ and show that this is a characteristic of all strong RS detections to date. The VLA observations exhibit unexpected rapid variability on $\sim$ minute timescales, indicative of strong interstellar scintillation. The X-ray, ALMA, and VLA observations together constrain the jet break time, $t_{\rm jet}\approx32$ day, yielding a wide jet opening angle of $θ_{\rm jet}\approx13^{\circ}$, implying beaming corrected $γ$-ray and kinetic energies of $E_γ\approx4.9\times10^{48}$ erg and $E_{\rm K}\approx1.3\times10^{50}$ erg, respectively. Comparing the RS and FS emission, we show that the ejecta are only weakly magnetized, with relative magnetization, $R_{\rm B}\approx1$, compared to the FS. These direct, multi-frequency measurements of a refreshed RS spanning the optical to radio bands highlight the impact of radio and millimeter data in probing the production and nature of GRB jets.

description: Portulaca oleracea L. (purslane) is a well-known edible and ethnomedicinal plant and it has been called “vegetable for long life” in the Chinese herbal medicine. The plant is recognized for the high content of polyphenols, including flavonoids and phenolic acids. In this study, hydromethanolic purslane extracts from Bulgarian and Greek locations were screened for polyphenolic content. Based on polyphenols, saponins and DPPH antioxidant activity, an orthogonal design L9(34) was performed in order to improve the ultrasound assisted extraction procedure of dry and fresh plant material. An UHPLC-Orbitrap-MS method in parallel-reaction monitoring mode was developed for the simultaneous identification and quantification of 14 compounds comprising hydroxybenzoic, hydroxycinnamic and caffeoylquinic acids, as well as 2 flavonol glycosides. The quantitative analysis was validated for curve fit, range, instrumental detection limit (IDL), instrumental quantification limit (IQL), LOD, LOQ, precision, recovery and accuracy. The UHPLC-MS quantification method revealed good linearity (r2 > 0.9950), LOD < 925.85 ng/g dw and LOQ < 3055.31 ng/g dw. Moreover, 11 cylco-dopa amides (Oleraceins A-D, N-Q, S, U and W) were tentatively identified through UHPLC-MS and their MS2 mass fragmentation was described.

description: Electrical generators are the starting point of a power system network, they produce electrical energy sufficient enough to feed the consumers. Almost all the generators used for this purpose are AC generators, by also using windmills we extract energy from the wind. A dual rotor wind turbine, according to the present invention includes a rotatable drive shaft, a first rotor assembly connected to the drive shaft, a second independently-rotating rotor assembly coupled to the drive shaft rearward of the first rotor assembly. This type of generators has a very large frictional and rotational losses, the vibrations produced in the tower will also be very high due to two rotating parts. The maintenance cost will also be high. This paper mainly concentrates on the reduction of the losses produced in the dual rotor generator without sacrificing its advantages. In other words, here we are making the generator a single rotor type and we are simulating the second rotor rotation by means of a series of electromagnet and power electronic switches which are switched in a particular manner. Dual rotor wind turbine is now being implemented in various country’s to achieve a greater relative velocity even in the midst of low wind velocity, TFG is such a kind of generator which is motivated from the dual rotor wind turbine.

description: Multiconfiguration Dirac-Hartree-Fock (MCDHF) and relativistic configuration interaction (RCI) calculations were performed for 28 and 78 states in neutral and singly ionized aluminium, respectively. In Al I, the configurations of interest are $3s^2nl$ for $n=3,4,5$ with $l=0$ to $4$, as well as $3s3p^2$ and $3s^26l$ for $l=0,1,2$. In Al II, the studied configurations are, besides the ground configuration $3s^2$, $3snl$ with $n=3$ to $6$ and $l=0$ to $5$, $3p^2$, $3s7s$, $3s7p$ and $3p3d$. Valence and core-valence electron correlation effects are systematically accounted for through large configuration state function (CSF) expansions. Calculated excitation energies are found to be in excellent agreement with experimental data from the NIST database. Lifetimes and transition data for radiative electric dipole (E1) transitions are given and compared with results from previous calculations and available measurements, for both Al I and Al II. The computed lifetimes of Al I are in very good agreement with the measured lifetimes in high-precision laser spectroscopy experiments. The present calculations provide a substantial amount of updated atomic data, including transition data in the infrared region. This is particularly important since the new generation of telescopes are designed for this region. There is a significant improvement in accuracy, in particular for the more complex system of neutral Al I. The complete tables of transition data are available.

description: Blazar OJ 287 is a candidate nanoHertz (nHz) gravitational wave (GW) source. In this article, we investigate the GWs generated by OJ 287 and their potential detection through a pulsar timing array (PTA). First, we obtain the orbit and the corresponding GW strain of OJ 287. During the time span of the next 10 years (2019 to 2029), the GW of OJ 287 will be active before 2021, with a peak strain amplitude $8 \times 10^{-16}$, and then decay after that. When OJ 287 is silent in the GW channel during 2021 to 2029, the timing residual signals of the PTA will be dominated by the 'pulsar term' of the GW strain and this provides an opportunity to observe this pulsar term. Furthermore, we choose 26 pulsars with white noise below 300 ns to detect the GW signal of OJ 287, evaluating their timing residuals and signal-to-noise ratios (SNRs). The total SNR (with a cadence of 2 weeks in the next 10 years) of the PTA ranges from 1.9 to 2.9, corresponding to a weak GW signal for the current sensitivity level. Subsequently, we investigate the potential measurement of the parameters of OJ 287 using these pulsars. In particular, PSR J0437-4715, with a precisely measured distance, has the potential to constrain the polarization angle with an uncertainty below $8^°$ and this pulsar will play an important role in future PTA observations.

description: The Chemical of Africa (CHEMAF) is a hydrometallurgical plant that was commissioned in 2001. It produces copper (Cu) cathodes and salts of cobalt (Co) using a process encompassing the sulphuric acid leaching of Cu-Co oxidised ores under reducing conditions (Na2S2O5 or SO2) followed by the leach liquor purification by solvent extraction (SX), electrowinning of copper and the precipitation of Co as hydroxides. The leach liquor is recovered via the thickening of pulps from the ores leaching section and the depletion in valuable metals of the leaching residues by washing inside the counter-current decanters (CCD). The hydrometallurgical residues from Cu production were anciently dumped near the plant. With the increase in the content sulphide minerals in the run of mine (ROM) ores brought about by variations in the mineralogy of the Kalukuluku deposit and considering that the storage of solid residues may result in toxic pollutant release to the environment, the reprocessing of solid residues constitutes a best management option. The present research aims at recovering Cu metal retained in hydrometallurgical solid residues (2.01% Cu and 0.32% Co) and utilizes a process based on the sulphuric acid leaching followed by the recovery of Cu as metal through cementation with iron shavings. After experiments, it has been observed that the leaching of the Cu (≈ 90%) and Co (86%) succeeded when 150 g of solid residues were stirred (500 rpm) during 90 minutes (at 75°C) in 1 L of an acid solution (H2SO4: 30 g/L) under reducing conditions (Na2S2O5), with the pulp’s redox potential maintained at 330 mV. Consequently, copper was recovered as metal (2.5 g of solids assaying 93% Cu recovered at 86%) when 1 g of iron shavings was stirred during 60 minutes, at room temperature and constant speed (400 rpm), in 250 mL of a metalliferous solution (10.84 g/L Cu and 1.73 g/L Co) prepared through the leaching of solid residues.

Looking for Z' bosons in Supersymmetric E_6 Models through Electroweak Precision Data
Creators: name: Cho, Gi-Chol
Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We review constraints on additional Z' bosons predicted in supersymmetric (SUSY) E_6 models from electroweak experiments - Z-pole experiments, mW measurements and the low-energy neutral current (LENC) experiments. Four representative models - χ,ψ, η, νmodels - are studied in some detail. We find that the improved data of parity violation in cesium atom, which is 2.2-σaway from the Standard Model (SM) prediction, could be explained by the exchange of the heavy mass eigenstate Z_2 in the intermediate state. The improvement over the SM can be found in χ, η, νmodels, where the total χ^2 of the fit to the 26 data points decreases by about five units, owing to the better fit to the atomic parity violation. Impacts of the kinetic mixing between the U(1)_Y and U(1)' gauge bosons on the χ^2-analysis are studied. We find that the Z' model with (β_E, δ)=(-π/4,0.2), where β_E is the mixing angle between Z_χand Z_ψbosons and δdenotes the kinetic mixing, shows the most excellent fit to the data: the total χ^2 decreases by about seven units as compared to the SM. We introduce the effective mixing parameter ζ, a combination of the mass and the kinetic mixing parameters. The 95% CL lower mass bound of Z_2 can be shown as a function of ζ. A theoretical prediction on ζand the U(1)'gauge coupling g_E is studied for the χ,ψ,ηand νmodels by assuming the minimal particle content of the SUSY E_6 models.

description: Predictive models over social media language have shown promise in capturing community outcomes, but approaches thus far largely neglect the socio-demographic context (e.g. age, education rates, race) of the community from which the language originates. For example, it may be inaccurate to assume people in Mobile, Alabama, where the population is relatively older, will use words the same way as those from San Francisco, where the median age is younger with a higher rate of college education. In this paper, we present residualized factor adaptation, a novel approach to community prediction tasks which both (a) effectively integrates community attributes, as well as (b) adapts linguistic features to community attributes (factors). We use eleven demographic and socioeconomic attributes, and evaluate our approach over five different community-level predictive tasks, spanning health (heart disease mortality, percent fair/poor health), psychology (life satisfaction), and economics (percent housing price increase, foreclosure rate). Our evaluation shows that residualized factor adaptation significantly improves 4 out of 5 community-level outcome predictions over prior state-of-the-art for incorporating socio-demographic contexts.

description: Metabolic modelling has entered a mature phase with dozens of methods and software implementations available to the practitioner and the theoretician. It is not easy for a modeller to be able to see the wood (or the forest) for the trees. Driven by this analogy, we here present a "forest" of principal methods used for constraint-based modelling in systems biology. This provides a tree-based view of methods available to prospective modellers, also available in interactive version at http://modellingmetabolism.net, where it will be kept updated with new methods after the publication of the present manuscript. Our updated classification of existing methods and tools highlights the most promising in the different branches, with the aim to develop a vision of how existing methods could hybridise and become more complex. We then provide the first hands-on tutorial for multi-objective optimisation of metabolic models in R. We finally discuss the implementation of multi-view machine-learning approaches in poly-omic integration. Throughout this work, we demonstrate the optimisation of trade-offs between multiple metabolic objectives, with a focus on omic data integration through machine learning.

description: Bose-Einstein condensation of light in 2D is characterized by two classical fields corresponding to two polarizations of light as well as by the distribution of dye molecules inducing light thermalization through dipolar transition. In the case when this transition is triple-degenerate the resulting field theory for the condensate of light is O(4) symmetric, which precludes algebraic long range order in 2D at any finite temperature $T$. If the dipolar degeneracy is removed, then, equilibrium phases with lower symmetries -- O(2)$\times$Z$_2$ and O(2) can emerge. Accordingly, algebraic off diagonal order of light condensate becomes possible. An orientationsl disorder introduced by local dipolar anisotropy can destroy algebraic order in one-photon density matrix while preserving it in the two-photon one. This represents formation of the condensate of photon pairs.

description: We study the spin injection efficiency into single and bilayer graphene on the ferrimagnetic insulator Yttrium-Iron-Garnet (YIG) through an exfoliated tunnel barrier of bilayer hexagonal boron nitride (hBN). The contacts of two samples yield a resistance-area product between 5 and 30 k$Ωμ$m$^2$. Depending on an applied DC bias current, the magnitude of the non-local spin signal can be increased or suppressed below the noise level. The spin injection efficiency reaches values from -60% to +25%. The results are confirmed with both spin valve and spin precession measurements. The proximity induced exchange field is found in sample A to be (85 $\pm$ 30) mT and in sample B close to the detection limit. Our results show that the exceptional spin injection properties of bilayer hBN tunnel barriers reported by Gurram et al. are not limited to fully encapsulated graphene systems but are also valid in graphene/YIG devices. This further emphasizes the versatility of bilayer hBN as an efficient and reliable tunnel barrier for graphene spintronics.

description: A rule of thumb derivation of the Dirac-Born-Infeld action for D-branes is studied à la Fradkin and Tseytlin, by simply integrating out of the superstring coordinates in a narrow strip attached to the D-branes. In case of superstrings, the coupling of Ramond-Ramond fields as well as the Dirac-Born-Infeld type coupling of the Neveu Schwarz-Neveu Schwarz fields come out in this way.

Spatial structure of anomalously localized states in disordered conductors
Creators: name: Mirlin, Alexander D.
Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: The spatial structure of wave functions of anomalously localized states (ALS) in disordered conductors is studied in the framework of the $σ$--model approach. These states are responsible for slowly decaying tails of various distribution functions. In the quasi-one-dimensional case, properties of ALS governing the asymptotic form of the distribution of eigenfunction amplitudes are investigated with the use of the transfer matrix method, which yields an exact solution to the problem. Comparison of the results with those obtained in the saddle-point approximation to the problem shows that the saddle-point configuration correctly describes the smoothed intensity of an ALS. On this basis, the properties of ALS in higher spatial dimensions are considered. We study also the ALS responsible for the asymptotic behavior of distribution functions of other quantities, such as relaxation time, local and global density of state. It is found that the structure of an ALS may be different, depending on the specific quantity, for which it constitutes an optimal fluctuation. Relations between various procedures of selection of ALS, and between asymptotics of corresponding distribution functions, are discussed.

description: This study aimed to determined the enhancement of material properties of EN24 pinion by heat treatment process. The process of heat treatment is carried out by heating the base material above critical temperature and then cooling with salt water, air and oil. The failure analysis was carried out on a failed pinion gear which is used for power transmission system in the automobile sector. The pinion gear is made of case carburized steel with low nickel and chromium content and it also has undergone extensive corrosion due to an environmental problem. The teeth are badly damaged and corroded at the surface. However, the crack has occurred due to stress and it is found only in certain places. To improve the corrosion resistance, nickel and chromium content are added and also heat treatment is carried out. The mechanical properties and wear resistance are improved in EN24 steel when compared to failure gear and EN24 steel before heat treatment.
Nonparametric Tests for Bivariate Stochastic Dominance without Continuity Assumptions

Publisher: name: arXiv
Year: 2018
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: The use of Kolmogorov-Smirnov-type statistics for testing stochastic dominance goes back to McFadden (1989). In this paper we extend the approach of Barret and Donald (2003) to the bivariate case, without the assumption of absolute continuity for the underlying distributions. Using empirical processes theory and bootstrap techniques we obtain consis- tent nonparametric tests for bivariate first and second order stochastic dominance, over several modularity classes of test functions. This tests are in turn useful tools in applied fields such as multidimensional eco- nomic inequality as shown by Perez (2015).
Confronting particle emission scenarios with strangeness data

description: We show that a hadron gas model with continuous particle emission instead of freeze out may solve some of the problems (high values of the freeze out density and specific net charge) that one encounters in the latter case when studying strange particle ratios such as those by WA85. This underlines the necessity to understand better particle emission in hydrodynamics to be able to analyze data. It also re-opens the possibility of a quark-hadron transition occuring with phase equilibrium instead of explosively.

Innovative Geotechnical Solutions: Comparative Study of Helical Pile Foundation System for Bridge Construction in Pakistan
Creators: name: Tahir, Muhammad
name: Rai, Partab
name: Yao, Huang
Publisher: name: Zenodo
Year: 2024

description: This research explores the feasibility and efficiency of helical pile foundation systems for bridge construction, specifically focusing on the challenges faced in the region of River Indus in Ghazi Ghat, Dera Ghazi Khan, Pakistan. The primary objective is to assess the viability of helical piles as a more sustainable, cost-effective, and technically efficient alternative to conventional pile foundations, particularly in challenging geotechnical conditions.

The study begins with a comprehensive review of existing foundation methods, highlighting the limitations of traditional pile systems in terms of environmental impact, cost, and adaptability to diverse soil profiles. The helical pile foundation, with its unique screw-like design, offers potential benefits including reduced installation time, immediate load-bearing capacity, and minimal environmental footprint. The research methodology incorporates a comparative analysis using advanced finite element method (FEM) simulations. These simulations, conducted via Plaxis-2D, evaluate the performance of helical piles against conventional piles under varying soil conditions and load scenarios.

Key aspects of the study include assessing the load-bearing capacity of helical piles, installation efficiency, and environmental implications. The research also explores the adaptation of international design codes for helical piles in the local context, considering regional soil characteristics and engineering practices. The results demonstrate a significant improvement in load capacity, reduction in the number of piles required, and overall cost savings when using helical piles. Moreover, the environmental benefits of this method are underscored, highlighting its alignment with sustainable engineering practices.

In conclusion, the study advocates for the integration of helical pile systems in bridge construction projects in Pakistan, particularly in regions with similar geotechnical challenges as those found at the River Indus site. The research underscores the need for continued innovation in foundation engineering, advocating for a shift towards more sustainable and efficient practices. Further studies are recommended to explore the long-term performance and broader applications of helical pile systems in various construction contexts.
