Diverse Exact Soliton Solutions of the Time Fractional Clannish Random Walker’s Parabolic Equation via Dual Novel Techniques

In this article, we acquire a variety of new exact traveling wave solutions in the form of trigonometric, hyperbolic, and rational functions for the nonlinear time-fractional Clannish Random Walker’s Parabolic (CRWP) equation in the sense of beta-derivative by employing the two modified methods, namely, modified G ′ / G 2 − expansion method and modified F − expansion method. The obtained solutions are verified for aforesaid equations through symbolic soft computations. To promote the essential propagated features, some investigated solutions are exhibited in the form of 2D and 3D graphics by passing on the precise values to the parameters under the constrain conditions. The obtained solutions show that the presented methods are effective, straight forward, and reliable as compared to other methods. These methods can also be used to extract the novel exact traveling wave solutions for solving any types of integer and fractional differential equations arising in mathematical physics.
HighIE: High-Order Inference for Entity Recognition, Relation Extraction, and Event Extraction

Most prior work on information extraction (IE) 001 typically predicts labels of individual instances 002 ( e.g ., event triggers, relations, entities) inde-003 pendently regardless of their interactions. We 004 propose a novel framework, HighIE, that aims 005 to integrate high-order cross-subtask and cross-006 instance dependencies in both learning and in-007 ference. High-order inference on label vari-008 ables is an NP-hard problem. To address it, 009 we propose a high-order decoder that is un-010 folded from an approximate inference algo-011 rithm. The experimental results show that 012 our approach achieves consistent improvement 013 compared with prior work. 1 014
CHROMOSPHERIC ACTIVITY OF SOUTHERN STARS FROM THE MAGELLAN PLANET SEARCH PROGRAM

I present chromospheric-activity measurements of ∼670 F, G, K, and M main-sequence stars in the Southern Hemisphere, from ∼8000 archival high-resolution echelle spectra taken at Las Campanas Observatory since 2004. These stars were targets from the Old Magellan Planet Search, and are now potential targets for the New Magellan Planet Search that will look for rocky and habitable planets. Activity indices (S values) are derived from Ca ii H and K line cores and then converted to the Mount Wilson system. From these measurements, chromospheric (log R′HK) indices are derived, which are then used as indicators of the level of radial-velocity jitter, age, and rotation periods these stars present.
The unfolded universe of elementary particles. A geometric explanation of the standard model structure

We propose a geometric explanation of the standard model of Glashow, Weinberg and Salam for the known elementary particles. Our model is a generic Quantum Field Theory in dimension four, obtained by developing along a Lorentz sub-manifold the lagrangian of Einstein and Dirac in dimension twelve. The main mechanism which gives birth to the standard model is a certain gauge fixing of triality, which permits to identify the multiplicity of fermions, as seen from the four dimensional world, with the eight unseen dimensions of the generating universe. In this way we get the known tables of particles, explaining the series of fermions and the gauge bosons. We suggest that the Higgs field dynamics could appear through a bosonization of the right handed neutrino and correspond to a displacement in the unseen dimensions. We also propose hypotheses for dark matter, and perhaps dark energy. Then we suggest predictions to go beyond the standard model.
NEUTRON STAR MERGERS AS THE ORIGIN OF r-PROCESS ELEMENTS IN THE GALACTIC HALO BASED ON THE SUB-HALO CLUSTERING SCENARIO

Recent hydrodynamical and nucleosynthesis studies have suggested binary mergers (NSMs) of double neutron star (and black-hole–neutron-star) systems as major sites of r-process elements in the Galaxy. It has been pointed out, however, that the estimated long lifetimes of neutron star binaries are in conflict with the presence of r-process-enhanced halo stars at metallicities as low as [Fe/H] ∼ − 3 ? > . To resolve this problem, we examine the role of NSMs in the early Galactic chemical evolution with the assumption that the Galactic halo was formed from merging sub-halos. We present simple models for the chemical evolution of sub-halos with total final stellar masses between 10 4 M ⊙ ? > and 2 × 10 8 M ⊙ ? > . The typical lifetimes of compact binaries are assumed to be 100 Myr (for 95% of their population) and 1 Myr (for 5%), according to recent binary population synthesis studies. The resulting metallicities of sub-halos and their ensemble are consistent with the observed mass–metallicity relation of dwarf galaxies in the Local Group and the metallicity distribution of the Galactic halo, respectively. We find that the r-process abundance ratios [r/Fe] start increasing at [Fe/H] ≤ − 3 ? > if the star formation efficiencies are smaller for less-massive sub-halos. In addition, sub-solar [r/Fe] values (observed as [Ba/Fe] ∼ − 1.5 ? > for [Fe/H] < − 3 ? > ) are explained by the contribution from short-lived (∼1 Myr) binaries. Our results indicate that NSMs may have contributed substantially to the r-process element abundances throughout the history of the Galaxy.
Package Aware LC-VCO With Self-Biased Switched Capacitor Structure for Better Supply Noise Rejection

This article proposes a packaged standalone <inline-formula> <tex-math notation="LaTeX">$LC$ </tex-math></inline-formula>-voltage-controlled oscillator (VCO) based on self-biased (SB) switched capacitor array (SCA) to facilitate large frequency tuning-range (TR). The proposed SB SCA achieves better supply noise rejection and is robust to quad flat no-lead package (QFN) package parasitics when compared with other existing SCA topologies without compromising the quality factor (<inline-formula> <tex-math notation="LaTeX">$Q$ </tex-math></inline-formula>-factor) of the SCA in OFF-state. A prototype SB SCA-based <inline-formula> <tex-math notation="LaTeX">$LC$ </tex-math></inline-formula>-VCO designed and fabricated in United Microelectronics Corporation (UMC) 65-nm complementary metal oxide semiconductor (CMOS) process oscillates from 1.54 to 2.54 GHz having a TR of 40% achieving a phase noise (PN) of <inline-formula> <tex-math notation="LaTeX">$\approx -96$ </tex-math></inline-formula> dBc/Hz at 100 kHz offset and an figure of merit (FoM) of ≈174 dBc/Hz at 100 kHz offset while consuming 10 mW of power from 2.5 V supply, thereby making it ideal for applications requiring QFN-packaged standalone VCOs.
Effect of Hunteria umbellata Methanolic Seed Extracts on Streptozotocin-induced Diabetic Albino Rats

This study investigated the inhibitory effect of alpha-amylase, LD50 and antidiabetic properties of the methanolic seed extract of Hunteria umbellata and its effect on biochemical parameters in streptozotocin-induced diabetic rats. Twelve albino rats were used for the acute toxicity test, while thirty-five were divided randomly into seven groups of five in each group. Group 1 served as the normal control, Group 2 served as the diabetic control, Group 3 was treated with glycinorm at 50 mg/kg body weight, Group 4 was treated with extract at 200 mg/kg body weight, Group 5 was treated with 400 mg/kg body weight, Group 6 was treated with 600 mg/kg body weight and Group 7 was treated with 800 mg/kg body weight by oral administration. Diabetes was induced in albino rats by intraperitoneal injection of streptozotocin at a single dose of 120 mg/kg body weight into groups 3 to 7 and was fed with methanolic seed extract of Hunteria umbellata for a period of 28 days. The oral acute (LD50) toxicity study showed that extract did not cause mortality in any experimental animals even at the highest dose of 5000 mg/kg. Body weight and glucose levels were measured on days 0, 7, 14,21 and 28. The animal were sacrificed on day 28. Serum biochemical parameters were analysed. Additionally, renal function tests, including potassium, sodium, and chloride levels and protein and albumin levels, were performed. The study also evaluated hematological parameters in the animals that were fed the methanolic seed extract of Hunteria umbellata. The animals that received different methanolic seed extracts of Hunteria umbellata showed significant (p<0.05) reductions in blood glucose, inhibitory effect of alpha-amylase, serum liver enzymes, renal function biomarkers, packed cell volume and platelet counts and improved body weight. Conclusively, from this study, it has been demonstrated that the methanolic seed extract of Hunteria umbellata may possess weight enhancing, inhibitory effect of alpha-amylase, antihyperglycemic, hepatoprotective, improved hematological values, and cell and organ protective activities. Therefore, it can be concluded that H. umbellata protects against streptozotocin-induced diabetes via regulation of blood glucose, inhibition of alpha amylase and reverse some biochemical parameters.
Possible signature of distant foreground in the Planck data

By using the Planck map of the cosmic microwave background (CMB) radiation we have checked and confirmed the existence of a correlation between supernova (SN) redshifts, $z_{\rm SN}$, and CMB temperature fluctuations at the SNe locations, $T_{\rm SN}$, which we previously reported for the Wilkinson Microwave Anisotropy Probe data. The Pearson correlation coefficient for the Planck data is $r=+0.38\pm 0.08$ which indicates that the correlation is statistically significant (the signal is about $5\sigma$ above the noise level). The correlation becomes even stronger for the type Ia subsample of SNe, $r_{\rm Ia}=+0.45\pm 0.09$, whereas for the rest of the SNe it is vanishing. By checking the slopes of the regression lines $T_{\rm SN} / z_{\rm SN}$ for Planck's different frequency bands we have also excluded the possibility of this anomaly being caused by the Sunyaev-Zeldovich effect. The remaining possibility is some, unaccounted for, contribution to the CMB from distant ($z>0.3$) foreground through either the integrated Sachs-Wolfe effect or thermal emission from intergalactic matter.
Efeito da adição de concentrado proteico de leite nas características do requeijão

A literatura tem evidenciado que a produção de requeijão culinário tem aumentado de forma significativa e, sem dúvida, seu potencial de crescimento é promissor. Os concentrados proteicos possuem proteína de qualidade, encontrada na forma desidratada. Essas proteínas, quando utilizadas como ingredientes em outros alimentos, podem contribuir para as características funcionais, sensoriais e reológicas no produto. O intuito deste estudo, foi avaliar a viabilidade tecnológica de Requeijão culinário, com a substituição total e parcial de massa enzimática por concentrado proteico de leite (Nutrilac BE-8405). O processamento das formulações dos requeijões, bem como as análises físico-químicas, cor, derretimento, consistência, “baking/blistering test” e sensorial foram realizadas no Laboratório de Leite e Derivados (INOVALEITE) do Departamento de Tecnologia de Alimentos (DTA/UFV), na Universidade Federal de Viçosa (UFV). A substituição parcial e total de massa fresca pelo concentrado proteico, na fabricação do requeijão não alterou significativamente os atributos analisados neste estudo. Quanto as características de consistência analisadas nos requeijões culinários, não houve alteração com a substituição da massa por Nutrilac BE-8405. Os tratamentos não apresentaram diferenças significativas para o quesito de derretimento, o que é um ponto muito importante para este produto. Os requeijões foram avaliados sensorialmente sobre o aspecto de aceitação. Na avaliação, os requeijões com maiores níveis de substituição, apresentaram uma boa aceitação dos provadores na escala hedônica. Com isso, a substituição total ou parcial da massa enzimática por Nutrilac BE-8405 pode gerar benefícios, como a padronização na formulação do produto, diminuição da mão de obra, e, principalmente, a não produção de soro, o que é um grande problema para as indústrias lácteas. Palavras-chave: Concentrado proteico. Substituição. Requeijão culinário. Massa enzimática.
Holography, heavy-quark free energy, and the QCD phase diagram

We use gauge/string duality to investigate the free energy of two static color sources (a heavy-quark-antiquark pair) in a Yang-Mills theory in strongly interacting matter, varying temperature and chemical potential. The dual space geometry is anti-de Sitter with a charged black hole to describe finite temperature and density in the boundary theory, and we also include a background warp factor to generate confinement. The resulting deconfinement line in the {mu}-T plane is similar to the one obtained by lattice and effective models of QCD.
Ripping apart at the seams: the network of stripped gas surrounding M86

We present a new study of the Virgo Cluster galaxies M86, M84, NGC 4338 and NGC 4438 using a mosaic of five separate pointings with XMM–Newton. Our observations allow for robust measurements of the temperature and metallicity structure of each galaxy along with the entire ∼1° region between these galaxies. When combined with multiwavelength observations, the data suggest that all four of these galaxies are undergoing ram pressure stripping by the intracluster medium (ICM). The manner in which the stripped gas trailing the galaxies interacts with the ICM, however, is observably distinct. Consistent with previous observations, M86 is observed to have a long tail of ∼1 keV gas trailing to the north-west for distances of ∼100–150 kpc. However, a new site of ∼0.6 keV thermal emission is observed to span to the east of M86 in the direction of the disturbed spiral galaxy NGC 4438. This region is spatially coincident with filaments of Hα emission, likely originating in a recent collision between the two galaxies. We also resolve the thermodynamic structure of stripped ∼0.6 keV gas to the south of M84, suggesting that this galaxy is undergoing both AGN feedback and ram pressure stripping simultaneously. These four sites of stripped X-ray gas demonstrate that the nature of ram pressure stripping can vary significantly from site to site.
A new period determination for the close PG1159 binary SDSSJ212531.92-010745.9

Methods to measure masses of PG1159 stars in order to test evolutionary scenarios are currently based on spectroscopic masses or asteroseismological mass determinations. One recently discovered PG1159 star in a close binary system may finally allow the first dynamical mass determination, which has so far been analysed on the basis of one SDSS spectrum and photometric monitoring. In order to be able to phase future radial velocity measurements of the system SDSSJ212531.92-010745.9, we follow up on the photometric monitoring of this system to provide a solid observational basis for an improved orbital ephemeris determination. New white-light time series of the brightness variation of SDSSJ212531.92-010745.9 with the Tuebingen 80cm and Goettingen 50cm telescopes extend the monitoring into a second season (2006), tripling the length of overall observational data available, and significantly increasing the time base covered. We give the ephemeris for the orbital motion of the system, based on a sine fit which now results in a period of 6.95573(5)h, and discuss the associated new amplitude determination in the context of the phased light curve variation profile. The accuracy of the ephemeris has been improved by more than one order of magnitude compared to that previously published for 2005 alone.
Redshifts of Distant Blazars Limited by Fermi and VHE γ-Ray Observations

Our goal is to limit the redshifts of three blazars, PG 1553+113, 3C 66A, and PKS 1424+240, through an investigation of their Fermi and VHE (very high energy) gamma-ray observations. We assume that the intrinsic spectra of PG 1553+113, 3C 66A, and PKS 1424+240 have no cutoff across the Fermi and VHE gamma-ray energy ranges. The intrinsic spectra of VHE gamma-rays are obtained through extrapolation of the Fermi spectra. Comparing the measured and intrinsic VHE spectra due to extragalactic background light (EBL) absorption, we give the redshift upper limits of three blazars, while assuming a specific EBL model. The redshift upper limits of PG 1553+113, 3C 66A, and PKS 1424+240 are 0.78, 0.58, and 1.19, respectively. Near to the TeV energy the optical depth of VHE gamma photons might be overestimated by the Franceschini EBL model (Franceschini et al. 2008, A&A, 487, 837), or the second emission component might be present in the VHE spectra and lead the intrinsic photon index to be harder than the Fermi ones.
Simulating supersonic turbulence in galaxy outflows

We present three-dimensional, adaptive mesh simulations of dwarf galaxy outows driven by supersonic turbulence. Here we develop a subgrid model to track not only the thermal and bulk velocities of the gas, but also its turbulent velocities and length scales. This allows us to deposit energy from supernovae directly into supersonic turbulence, which acts on scales much larger than a particle mean free path, but much smaller than resolved large-scale ows. Unlike previous approaches, we are able to simulate a starbursting galaxy modeled after NGC 1569, with realistic radiative cooling throughout the simulation. Pockets of hot, diuse gas around individual OB associations sweep up thick shells of material that persist for long times due to the cooling instability. The overlapping of high-pressure, rareed regions leads to a collective central outow that escapes the galaxy by eating away at the exterior gas through turbulent mixing, rather than gathering it into a thin, unstable shell. Supersonic, turbulent gas naturally avoids dense regions where turbulence decays quickly and cooling times are short, and this further enhances density contrasts throughout the galaxy{ leading to a complex, chaotic distribution of bubbles, loops and laments as observed in NGC 1569 and other outowing starbursts.
Transformer rail‐tapped buck‐boost converter design‐based feedback controller for battery charging systems

In this article, a transformer rail‐tapped buck‐boost converter (TRT‐BBC) with minor loss of power transfer from a photovoltaic solar panel to a lead‐acid battery for battery charging systems is designed. The TRT‐BBC has been utilized to inter‐match the PV direct power to the battery. The 24‐V lead acid battery bank with a storage energy of approximately 168 Wh is designed. The photovoltaic solar panel of 200 W maximum power is used for the whole system operation. The proposed TRT‐BBC topology solves the conventional buck‐boost converter inverted output problem with apex conversion efficiencies of 93.25% and 91.97% for continuous current mode (CCM) and discontinuous current mode (DCM) respectively at standard test conditions (STC) and full load conditions. The whole system can operate either in DCM or CCM according to the needs at a switching frequency of 100 kHz and the maximum power point tracking (MPPT) with proportional integration (PI) based constant voltage‐constant current (CV‐CC) feedback control loop used to monitor the switching duty cycle of the TRT‐BBC.
Characterization of Bond Fracture in Discrete Groove Wear of Cageless Ball Bearings

Cageless ball bearings with discrete grooves in the outer raceway enable the dispersion of rolling elements. Once worn, the discrete groove can cause the rolling element to discretely fail. This paper presents the discrete element method to investigate the wear of discrete grooves in cageless bearings from the standpoint of bond fracture. In conjunction with the structural characteristics of bearing races with discrete slots, we propose a hexagonal close-spaced spherical particle arrangement, in which the discrete slots are discretized into particles of the same size that are connected by bonds. The contact model and contact force equation between the rolling elements and the aggregate elements are established, and the external force on the aggregate elements is calculated. Under the influence of an external force and the arrangement of particles in the aggregate element, the internal force transfer equation of different layers and different particles is derived, and the internal force of the particles in the aggregate unit is calculated. In accordance with Hertz–Mindline theory, the bonding model of discrete groove particles is established, the size of the particle shedding cohesive force during bond fracture is determined, and the wear degree of discrete grooves is characterized by comparing the cohesive force and internal force. Numerical solutions and wear tests are combined. Bond fracture can accurately characterize the wear of discrete grooves. This approach offers theoretical guidance for cageless bearing design.
How Did the Built Environment Affect Urban Vibrancy? A Big Data Approach to Post-Disaster Revitalization Assessment

Quantitative assessment of urban vibrancy is crucial to understanding urban development and promoting sustainability, especially for rapidly developing areas and regions that have experienced post-disaster reconstruction. Taking Dujiangyan City, the hardest-hit area of the earthquake, as an example, this paper quantifies the urban economic, social, and cultural vibrancy after reconstruction by the use of multi-source data, and conducts a geographic visualization analysis. The purpose is to establish an evaluation framework for the relationship between the urban built environment elements and vibrancy in different dimensions, to evaluate the benefits of post-disaster restoration and reconstruction. The results show that the urban vibrancy reflected by classified big data can not be completely matched due to the difference in the data generation and collection process. The Criteria Importance Though Inter-criteria Correlation and entropy (CRITIC-entropy) method is used to construct a comprehensive model is a better representation of the urban vibrancy spatial characteristics. On a global scale, comprehensive vibrancy demonstrates high continuity and a bi-center structure. In the old town, the distribution of various urban vibrancies show diffusion characteristics, while those in the new district demonstrated a high degree of aggregation, and the comprehensive vibrancy is less sensitive to land-use mixture and more sensitive to residential land.

FinTech innovations enable the provision of financial services to many unbanked across the world by increasing access. The key role of FinTech to drive financial inclusion however suffers significant impediments including the digital divide. Nevertheless, there is paucity of elaborate theories on financial inclusion while extant literature on FinTech only identify factors that drive its acceptance and use with little attention to inhibitors such as the digital divide. Employing the unified theory of acceptance and use of technology (UTAUT2) and the model of digital inequality, this study investigates the impact of FinTech usage on financial inclusion amidst the digital divide. A structural equation modelling technique is applied to data collected from 282 respondents in a survey. The findings confirm the influence of performance expectancy and facilitating conditions on behavioural intentions as well as a positive influence of FinTech use on financial inclusion. The results also show that digital divide measured with access, resource and force moderate the use of FinTech. Significant theoretical contributions are made by the study and practical and policy implications are offered for deepening financial inclusion.
