Creators: name: Srinivas, M.

Publisher: name: Zenodo
Year: 2021

description: Leishmaniasis is a parasitic disease caused by an obligate intracellular protozoan from the genus Leishmania. Leishmania donovani, L.infantum and L.chagasi are commonly the species that are implicated in the disease. Leishmaniasis is a tropical and a subtropical disease caused by an intracellular parasite transmitted to humans by the bite of a sand fly (Phlebotomus and Lutzomyia) usually found in Europe, Northern Africa, the Middle East, Asia, and parts of South America. Human Visceral Leishmaniasis is a lethal form of leishmaniasis caused by Leishmania donovani, and contributes significantly to the annual burden of infectious diseases of India. The failure of management studies the deadline for the kala azar eradication program from 2012 to 2015 and further upto 2020 and still there is no particular deadline yet due to the ongoing pandemic. Leishmania infects three layers of the body namely cutaneous, mucocutaneous and visceral layers involving skin, mucous membranes and visceral organs respectively. The protozoan Leishmania donovani requires a particular enzyme Flip Endonuclease I for the DNA replication and repair. It is a structure specific nuclease with 5’-flap endonuclease and 5’-3’ exonuclease activities involved in DNA replication and repair. It targets the 5 - overhanging flap endonuclease and cleaves the structure that is generated by the displacement synthesis by DNA polymerase when it encounters the 5’-end of an Okazaki fragment, and also involved in nick ligation. Blocking the action of this enzyme by suitable inhibitor compounds can emerge as a therapeutic approach for the treatment and eradication of the kala azar, and would lead to decreased stability and defective replication of the genome. Computational methods and Virtual screening for the potential novel inhibitor molecules against the target Flap Endonuclease 1 are very useful for finding a novel drug molecule. In the present study, we have constructed and refined the Flap Endonuclease I structure by homology models based on two different templates; (PDB: 1UL1 and 5ZOD) and then docking the modelled enzyme molecule with the screened potential inhibitor compounds through in-silico studies. A detailed study of the binding energies and properties of the compounds have been done by using Accelrys Discovery Studio 2.1 and Swiss PDB Software.

description: We consider instanton solutions of Euclidean Horava-Lifshitz gravity in four dimensions satisfying the detailed balance condition. They are described by geometric flows in three dimensions driven by certain combinations of the Cotton and Ricci tensors as well as the cosmological-constant term. The deformation curvature terms can have competing behavior leading to a variety of fixed points. The instantons interpolate between any two fixed points, which are vacua of topologically massive gravity with Lambda > 0, and their action is finite. Special emphasis is placed on configurations with SU(2) isometry associated with homogeneous but generally non-isotropic Bianchi IX model geometries. In this case, the combined Ricci-Cotton flow reduces to an autonomous system of ordinary differential equations whose properties are studied in detail for different couplings. The occurrence and stability of isotropic and anisotropic fixed points are investigated analytically and some exact solutions are obtained. The corresponding instantons are classified and they are all globally R x S^3 and complete spaces. Generalizations to higher-dimensional gravities are also briefly discussed.

description: We propose a quantum optical interface between an atomic and solid state system. We show that quantum states in a single trapped atom can be entangled with the states of a semiconductor quantum dot through their common interaction with a classical laser field. The interference and detection of the resulting scattered photons can then herald the entanglement of the disparate atomic and solid-state quantum bits. We develop a protocol that can succeed despite a significant mismatch in the radiative characteristics of the two matter-based qubits. We study in detail a particular case of this interface applied to a single trapped \Yb ion and a cavity-coupled InGaAs semiconductor quantum dot. Entanglement fidelity and success rates are found to be robust to a broad range of experimental nonideal effects such as dispersion mismatch, atom recoil, and multi-photon scattering. We conclude that it should be possible to produce highly entangled states of these complementary qubit systems under realistic experimental conditions.

description: (Abridged) We measure the fraction of galaxies undergoing disk-disk major mergers (f_m) at intermediate redshifts (0.35 <= z < 0.85) by studying the asymmetry index A of galaxy images. Results are provided for B- and Ks-band absolute magnitude selected samples from the Groth strip in the GOYA photometric survey. Three sources of systematic error are carefully addressed: (i) we avoid morphological K-corrections, (ii) we measure asymmetries in artificially redshifted to z_d = 0.75 galaxies to lead with loss of morphological information with redshift, and (iii) we take into account the observational errors in z and A, that tend to overestimate the merger fraction, by maximum likelihood techniques. We find: (i) our data allow for a robust merger fraction to be provided for a single redshift bin centered at z=0.6. (ii) Merger fractions have low values: f_m = 0.045 for M_B <= -20 galaxies, and f_m = 0.031 for M_Ks <= -23.5 galaxies. And, (iii) failure to address the effects of the observational errors leads to overestimating f_m by factors of 10%-60%. Combining our results with those on literature, and parameterizing the merger fraction evolution as f_m(z) = f_m(0)(1+z)^m, we obtain that m = 2.9 +- 0.8, and f_m(0) = 0.012 +- 0.004$. Assuming a Ks-band mass-to-light ratio not varying with luminosity, we infer that the merger rate of galaxies with stellar mass M >= 3.5x10^10 M_Sun is R_m = 1.6x10^-4 Mpc^-3 Gyr^-1. When we compare with previous studies at similar redshifts, we find that the merger rate decreases when mass increases.

description: This supplementary material provides information regarding a heat map that illustrates the average human population migration in the top 50 cities. The map arranges these cities geographically by sorting their locations in ascending order of latitude to improve the visibility of patterns. The colour intensity on the heat map represents the magnitude of population migration between cities, with darker shades signifying higher migration. Furthermore, it delves into the patterns of population migration observed in the map, both in the North-South and East-West directions.

description: Using recent precise hadronic tau-decay data on the V-A spectral function, and general properties of QCD such as analyticity, the operator product expansion and chiral perturbation theory, we get accurate values for the QCD chiral order parameters L_10^r(M_rho) and C_87^r(M_rho). These two low-energy constants appear at order p^4 and p^6, respectively, in the chiral perturbation theory expansion of the V-A correlator. At order p^4 we obtain L_10^r(M_rho) = -(5.22\pm 0.06)10^{-3}. Including in the analysis the two-loop (order p^6) contributions, we get L_10^r(M_rho) = -(4.06\pm 0.39)10^{-3} and C_87^r(M_rho) = (4.89\pm 0.19)10^{-3}GeV^{-2}. In the SU(2) chiral effective theory, the corresponding low-energy coupling takes the value \overline l_5 = 13.30 \pm 0.11 at order p^4, and \overline l_5 = 12.24 \pm 0.21 at order p^6.

description: Selenium is an essential micronutrient that enhances the fungal disease resistance in plants when available at lower levels; however, at higher levels, the micronutrient shows toxic effects. Hence, plants have evolved a methionine S-methyltransferase (MSMT)-based mechanism that metabolizes selenium into selenoamino acid to regulate the availability of this micronutrient at precise levels. Using data-mining tools the regulatory roles of MSMT in selenoamino acid metabolism have been characterized in the present study. Phylogenetic analysis showed a wide distribution of different protein derivates, closely linked to MSMT, across the plant species studied. Three conserved domains of MSMT were found at variable positions across all the homologous protein sequences analyzed through motif-based sequence analysis tools (MEME Suite). Nine transcription factor binding sites, involved in various fundamental biological, cellular and molecular functions, could be identified in MSMT through gene ontology (GO) analysis. Various plant small RNA target sites identified in MSMT suggest that it plays a crucial role in post-transcriptional modifications of the selenoamino acid metabolism pathway. This is the first report on in-silico characterization of functional, regulatory and structural properties of MSMT concerning the metabolism of selenium into selenoamino acid. Further, the study suggests that MSMT can be manipulated to enhance the fungal disease resistance in plants.
Dietary protein restriction alters food-related behaviour and the activity of the mesolimbic pathway

description: Evolution has provided species with adaptive behavioural mechanisms that guarantee tight dietary protein regulation. However, little is known about how the brain encodes protein need. Here, we elucidate the contribution of the brain reward system in maintaining balanced protein status, examine whether protein need alters food-related motivation and whether protein appetite is innate or learned. We assessed c-fos expressing neurons in the dorsal striatum and nucleus accumbens (NAc) in protein restricted (5% protein diet) and non-restricted (20% protein) rats, after consumption of protein and carbohydrate-containing solutions. After, in two separate cohorts, we expressed the calcium indicator, GCaMP6s, in ventral tegmental area (VTA), or the dopamine sensor, dLight1.2, in the NAc core, and used fibre photometry to measure neural activity or dopamine release during nutrients intake. Additionally, we investigated temporal dynamics of protein consumption when rats first experienced nutrients. Finally, we used a progressive ratio task with protein-rich and nutritionally balanced pellets. Consumption of protein increased the density of c-Fos positive cells in the NAc core and shell of both protein-restricted and non-restricted rats. In photometry experiments, protein consumption, relative to carbohydrate, was associated with elevated VTA activation in protein-restricted rats only. Conversely, carbohydrate consumption was associated with increased dopamine release in the NAc core of nonrestricted rats only. We found that protein was preferred over carbohydrate within the first 5 minutes of exposure to nutrients. Finally, breakpoint for casein pellets was increased in protein-restricted rats, relative to non-restricted controls, whereas there was no difference between groups when nutritionally balanced pellets were used. Altogether, these results indicate an involvement of VTA and NAc in modulating protein appetite. Additionally, protein need elevates the motivation for protein food, and protein appetite does not require previous learning about nutrients to develop. These findings, beyond contributing to the literature, may have positive repercussions for human health.

description: Type 2 diabetes mellitus is caused by genetic, environmental, behavioral and other risk factors and characterized by hyperglycemia, insulin resistance (IR), and relative insulin deficiency. Herein, we aim to report the hub genes involved in type 2 diabetes mellitus by carrying differential gene expression analysis followed by their enrichment studies and pathways involved. Present study gives an account on the up-regulated and down-regulated genes which showed significant expression. Hub genes were selected to construct protein-protein networks. Among the differentially expressed genes, top five genes involved in type 2 diabetes mellitus therapy are taken into consideration for further enrichment analysis. Besides the evident genes like , insulin-like growth factor-binding protein (IBP1), insulin isoform 2 (INSR2) and insulin-like growth factor 1 (IGF1), other genes out of top five includes- glucokinase regulator(GCKR), free fatty acid receptor 3 (FFAR3), adenylate cyclase type 5 (ADCY5) and C-reactive protein (CRP) as more than 5-fold change (FC) values were observed, also, pathways associated to them were thoroughly studied like MAPK,P13-AKT signaling pathways. Regulatory networks are constructed using these shortlisted genes keeping nodes to be INSR and CRP which tend to give rise to more interacting proteins like IRS1,MED1,ESR1, etc , hence suggesting novelty in predicting onset of type 2 diabetes mellitus therapy.

description: [abridged] Our knowledge of the inner structure of embedded massive young stellar objects is still quite limited. We attempt here to overcome the spatial resolution limitations of conventional thermal infrared imaging. We employed mid-infrared interferometry using the MIDI instrument on the ESO/VLTI facility to investigate M8E-IR, a well-known massive young stellar object suspected of containing a circumstellar disk. Spectrally dispersed visibilities in the 8-13 micron range were obtained at seven interferometric baselines. We resolve the mid-infrared emission of M8E-IR and find typical sizes of the emission regions of the order of 30 milli-arcseconds (~45 AU). Radiative transfer simulations have been performed to interpret the data. The fitting of the spectral energy distribution, in combination with the measured visibilities, does not provide evidence for an extended circumstellar disk with sizes > 100 AU but requires the presence of an extended envelope. The data are not able to constrain the presence of a small-scale disk in addition to an envelope. In either case, the interferometry measurements indicate the existence of a strongly bloated, relatively cool central object, possibly tracing the recent accretion history of M8E-IR. In addition, we present 24.5 micron images that clearly distinguish between M8E-IR and the neighbouring ultracompact HII region and which show the cometary-shaped infrared morphology of the latter source. Our results show that IR interferometry, combined with radiative transfer modelling, can be a viable tool to reveal crucial structure information on embedded massive young stellar objects and to resolve ambiguities arising from fitting the SED.

description: Airy integrals are very classical but in recent years they have been generalized to higher dimensions and these generalizations have proved to be very useful in studying the topology of the moduli spaces of curves. We study a natural generalization of these integrals when the ground field is a non-archimedean local field such as the field of p-adic numbers. We prove that the p-adic Airy integrals are locally constant functions of moderate growth and present evidence that the Airy integrals associated to compact p-adic Lie groups also have these properties.

description: Plasma instabilities (e.g., Buneman, Weibel and other two-stream instabilities) excited in collisionless shocks are responsible for particle (electron, positron, and ion) acceleration. Using a new 3-D relativistic particle-in-cell code, we have investigated the particle acceleration and shock structure associated with an unmagnetized relativistic electron-positron jet propagating into an unmagnetized electron-positron plasma. The simulation has been performed using a long simulation system in order to study the nonlinear stages of the Weibel instability, the particle acceleration mechanism, and the shock structure. Cold jet electrons are thermalized and slowed while the ambient electrons are swept up to create a partially developed hydrodynamic (HD) like shock structure. In the leading shock, electron density increases by a factor of 3.5 in the simulation frame. Strong electromagnetic fields are generated in the trailing shock and provide an emission site. We discuss the possible implication of our simulation results within the AGN and GRB context.

description: This paper gives a note on an application of the enclosure method to an inverse obstacle scattering problem governed by the Helmholtz equation in two dimensions. It is shown that one can uniquely determine the convex hull of an unknown sound-hard polygonal obstacle from the trace of the total wave that was exerted by a single point source onto a known circle surrounding the obstacle provided the source is sufficiently far from the obstacle. The result contains a formula that extracts the value of the support function of the obstacle at a generic direction. Some other applications to thin obstacles, obstacles in a layered medium and the far-field equation in the linear sampling method are also included.

The Role of Homoacetogenic bacterial strain in carbon mitigation and acetic acid production
Creators: name: Jha, Avinash Kumar
Publisher: name: Zenodo
Year: 2021

description: Climate change mitigation has become a primary challenge of the global energy and environmental policy for the last two decades. The threats of extreme climatic events for humans and the sustainability of natural ecosystems have urged policymakers to reduce the increasing anthropogenic emissions of greenhouse gasses (GHG), particularly CO2, which contributes approximately 65% of the total annual GHG emissions. Apart from its negative effects on the climate, CO2 is also a valuable resource, containing carbon – one of the most used and processed elements on Earth. It is clear by now that there is a need to remove the surplus of CO2 from the atmosphere. Not many processes actually exist or are exploited in an industrial scale that sequester CO2 from the air, despite the fact that CO2 can be an interesting feedstock for many processes generating valuable chemicals. The main objectives of this research are the isolation of novel homoacetogenic strain and their use in the field of acetic acid production with lignocellulosic material (Rice straw). At present, the production of acetic acid by microbial fermentation uses starchy food crops as raw materials, which is costly and increases waste. Therefore, it is necessary to develop materials with a wider range of sources which will also be a cost-effective measure. Such as biomass, syngas, bio-fermentation gas, fuel combustion exhaust gas and other widely distributed and abundant carbon sources, all of which can be converted into acetic acid under the metabolism of homoacetogenic bacteria. That can not only reduce the cost, but also enable the chemical industry to continue to develop.

description: Radially inhomogeneous gamma-ray burst (GRB) jets release variable photospheric emission and can have internal shocks occurring above the photosphere. We generically formulate a photospheric emission model of GRBs including Compton up-scattered photospheric (UP) emission off the electrons (and positrons) in the internal shocks, and find that the photospheric emission may correspond to the traditional (Band) component at ~ 10 MeV. The two components can be separate in the spectrum in some cases or can mimic a smooth broad Band spectrum in other cases. We apply our formulation to the well-studied long and short LAT GRBs, GRB 080916C, GRB 090902B, and GRB 090510, and typically find reasonable parameters for fitting the time-binned spectra, although fine tuning of several parameters is required. The observed delays of the high-energy emission with respect to the MeV emission which are large compared to the variability times are unlikely to be due to simple kinematic effects of a non-evolving jet. These delays may be attributed to the temporal evolution of the physical parameters of the jet, and thus the delay timescales could provide a potential tool for investigating the structures of GRB jets themselves and their progenitors. The difference of the delay timescales of long and short GRBs inferred from the Fermi data might be due to the differences in the progenitors of long and short GRBs. Some other properties and consequences of this model are discussed, including temporal correlations among the prompt optical, the soft X-ray, and the distinct high-energy component as well as the Band component.

Evaluation of Phytoremediation Potential of selected Marigold plant species for removal of Heavy Metals from Soil
Creators: name: Hirapure, Pradip

Publisher: name: Zenodo
Year: 2021

description: Environmental contamination of soil by heavy metals is a serious problem worldwide due to their toxicity, immutable nature, accumulation in food chain and continued persistence in ecosystem. Conventional technologies involve physical displacement or chemical replacement, generating yet another problem of toxic sludge. Phytoremediation is a cost-effective, non-intrusive, and aesthetically pleasing technology in which herbaceous plants and trees are used to remediate and remove pollutants from soils. Applying ornamental plants for phytoremediation could be useful, for example in contaminated urban areas, because these plants can also improve the environment by their decorative value. In this study three species of Marigold plants Calendula officinalis, Tagetes erecta, Tagetes patula were assessed for their heavy metal accumulation potential. Pot experiments were conducted for various concentrations of heavy metals (ranging from 10 mg/kg to 200 mg/kg). The plant uptake of the heavy metals was analyzed after a 12-week growing period and was determined by analyzing residual heavy metal concentrations in aerial and subterranean parts of the plant by atomic absorption spectrophotometry (AAS). A comparison has been made for the bioaccumulation factor (BAF), translocation factor of all these plant for Chromium, Lead, Cadmium and Arsenic. According to the obtained outcome all these three species of marigold found to be efficient bioaccumulater of Chromium, Lead, Cadmium and Arsenic from contaminated soils, since it can accumulate these heavy metals in its tissues, and plant biomass do not decrease due to excessive amounts of heavy metals. Pot marigold Calendula officinalis can accumulate Chromium, Lead, Cadmium and Arsenic however it is more sensitive to the toxicity of heavy metals than Tagetes erecta and Tgetes patula. All these three species of marigold plants can be used in an environment-friendly approach for treating heavy metal contaminated landfills developed using heavy metal contaminated riverbed sediments.

The detection of considerable geographic structure in taxa from the arid Nearctic has prompted research into the drivers of isolation in the region. Several geographic features have been proposed as barriers to gene flow, including the Colorado River, Western Continental Divide, and a hypothetical Mid-Peninsular Seaway in Baja California. However, recent studies suggest that the role of barriers in genetic differentiation may have been overestimated when compared to other mechanisms of divergence. In this study, we infer historical and spatial patterns of connectivity and isolation in Desert Spiny Lizards (Sceloporus magister) and Baja Spiny Lizards (S. zosteromus), which together form a species complex composed of parapatric lineages with wide distributions in arid western North America. Our analyses incorporate mitochondrial sequences, genomic-scale data, and past and present climatic data to evaluate the nature and strength of barriers to gene flow in the region. Our approach relies on estimates of migration under the multispecies coalescent to understand the history of lineage divergence in the face of gene flow. Results show that the S. magister complex is geographically structured, but we also detect instances of gene flow. The Continental Divide is a strong barrier to gene flow, while the Colorado River is more permeable. Analyses yield conflicting results for the catalyst of differentiation of peninsular lineages in S. zosteromus. Our study shows how large-scale genomic data for thoroughly sampled species can shed new light on biogeography. Furthermore, our approach highlights the need for the combined analysis of multiple sources of evidence to adequately characterize the drivers of divergence.

description: Цель – изучение структуры больных с острыми кровотечениями из верхних отделов пищеварительного
тракта. Материал и методы. Проанализированы причины острых кровотечений из верхних отделов желудочно-кишечного тракта у 1 299 пациентов, пролеченных стационарно в течение 2018–2020 гг. в Нижневартовской
окружной больнице Ханты-Мансийского автономного округа – Югры. Результаты. Данная патология составила
18,5 % от общего числа острых хирургических патологий у пациентов, поступивших в экстренном порядке в хирургический стационар. Средний возраст больных – 53 ± 14,3 года; 72,3 % госпитализированных – мужчины.
Установлено, что доля кровотечений язвенного генеза достигает 48,7 %, реже причинами кровотечений являются: эрозивные поражения слизистой желудочно-кишечного тракта – 27,6 %, синдром Маллори – Вейсса – 8,3 %, варикозно-расширенные вены пищевода и желудка – 7,6 %, неоплазии – 6,7 %, ангиодисплазии – 1,1 %. У 33,7 % пациентов при первичной эзофагогастродуоденоскопии выявлено продолжающееся кровотечение. Предварительное промывание желудка и седация позволили повысить информативность первичной эзофагогастродуоденоскопии до 93,7 %.
description: The study aims to investigate the patients’ profile with acute bleeding from the upper gastrointestinal tract.
Material and methods. The causes of upper gastrointestinal bleeding in 1,299 patients treated in Nizhnevartovsk
Regional Clinical Hospital, Khanty-Mansi Autonomous Okrug – Ugra, Russia, during 2018–2020 are analyzed.
Results. Тhis pathology accounted for 18.5% of the total number of patients with acute surgical pathology who
were admitted urgently to a surgical unit. The average age of the patients was 53 ± 14.3 years, and 72.3% of
those hospitalized are men. It was found that the proportion of peptic ulcer bleeding reaches 48.7%, less often
the causes of bleeding are erosive lesions of the gastrointestinal mucosa (27.6%), Mallory–Weiss syndrome
(8.3%), esophageal and gastric varices (7,6%), neoplasia (6.7%), angiodysplasia (1.1%). In 33.7% of patients
with primary esophagogastroduodenoscopy, prolonged bleeding was revealed. Preliminary gastric lavage and
sedation made it possible to increase the information content of primary esophagogastroduodenoscopy to
93.7%.

description: The magnetic field dependence of the in-plane magnetic penetration depth for optimally doped SmFeAsO_(1-x)F_y was investigated by combining torque magnetometry, SQUID magnetometry, and muon-spin rotation. The results obtained from these techniques show all a pronounced decrease of the superfluid density as the field is increased up to 1.4 T. This behavior is analysed within a two-band model with self-consistently derived coupled gaps, where the superfluid density related to the larger gap is field independent and the superfluid density related to the smaller gap is strongly suppressed with increasing field.

description: We study thermoelectric properties of granular semiconductors with weak tunneling conductance between the grains, g_t < 1. We calculate the thermopower and figure of merit taking into account the shift of the chemical potential and the asymmetry of the density of states in the vicinity of the Fermi surface due to n- or p-type doping in the Efros-Shklovskii regime for temperatures less than the charging energy. We show that for weakly coupled semiconducting grains the figure of merit is optimized for grain sizes of order 5nm for typical materials and its values can be larger than one. We also study the case of compensated granular semiconductors and show that in this case the thermopower can be still finite, although two to three orders of magnitude smaller than in the uncompensated regime.

Long Term with Dasatinib Therapy Among Imatinib-Intolerant Patients with Chronic Phase Chronic Myeloid Leukemia: A Randomized Study
Creators: name: Dutta, Amit Kumar
Publisher: name: Zenodo
Year: 2021

description: Imatinib is the standard-of-care treatment for most chronic myeloid leukemia (CML) patients in chronic phase (CP). However, some patients suffer from low-grade side-effects that, in the long run, severely affect the quality of life and require treatment discontinuation due to toxicities. Analog of Imatinib Therapy, the second-generation tyrosine kinase inhibitor dasatinib, used as second-line treatment, has shown to be a valid option in patients with CP-CML after intolerance to prior Imatinib Therapy. Achieving early molecular response as a reduction in BCR-ABL1 transcripts to ≤10% at 6 months after initiating tyrosine kinase inhibitor treatment, has been shown to improve the probability of achieving a subsequent deep molecular response and to be associated with superior progression-free and overall survival in chronic myeloid leukemia in chronic phase (CML-CP). Treatment was well tolerated, and side-effects were mild. The results of this first prospective study support early monitoring of patients treated with first line imatinib, and suggest that switching to Dasatinib in cases of suboptimal response may offer clinical benefit. This finding, although limited to a small cohort of CP-CML patients, supports the view that a therapy switch from Imatinib to Dasatinib induces a reduction of symptom burden, improves patient compliance and shows clinical efficacy in achieving and sustaining deep molecular responses. Further Long-term follow-up is needed to assess the long-term clinical benefit of early switching.

description: Normal dynamics in a quasi-one-dimensional channel of length L (\to\infty) of N hard spheres are analyzed. The spheres are heterogeneous: each has a diffusion coefficient D that is drawn from a probability density function (PDF), W D^(-γ), for small D, where 0\leqγ<1. The initial spheres' density ρ is non-uniform and scales with the distance (from the origin) l as, ρ l^(-a), 0\leqa\leq1. An approximation for the N-particle PDF for this problem is derived. From this solution, scaling law analysis and numerical simulations, we show here that the mean square displacement for a particle in such a system obeys, ~t^(1-γ)/(2c-γ), where c=1/(1+a). The PDF of the tagged particle is Gaussian in position. Generalizations of these results are considered.

description: Solanum lyratum Thunb is a traditional Chinese medicinal with a significant clinical outcome for tumor treatment; however, chemicals or fractions separated from the herb did not exhibit strong and comparable efficacy. To investigate the potential synergy or antagonism among chemicals in the extract, we obtained the compounds solavetivone (SO), tigogenin (TI) and friedelin (FR) from the herb. The anti-tumor effects of these three monomer compounds alone or in combination with the anti-inflammatory compound DRG were also tested in this study. SO, FR and TI used alone did not inhibit the proliferation of A549 and HepG2 cells, but the combination of the three achieved 40% inhibition. In vitro anti-inflammatory analysis showed that DRG had a stronger anti-inflammatory effect than TS at the same concentration, and the combination of DRG with SO, FR or TI inhibited the anti-tumor effect of DRG. This is the first study that documented the synergistic and antagonistic interactions between different compounds in a single herb.

description: We study cosmological implications of a Lorentz invariance violating DGP-inspired braneworld scenario. A minimally coupled scalar field and a single, fixed-norm, Lorentz-violating timelike vector field within an interactive picture provide a wide parameter space which accounts for late-time acceleration and transition to phantom phase of the scalar field.

description: In this paper we study generalized J-inner matrix valued functions which appear as resolvent matrices in various indefinite interpolation problems. Reproducing kernel indefinite inner product spaces associated with a generalized J-inner matrix valued function W are studied and intensively used in the description of the range of the linear fractional transformation associated with W and applied to the Schur class. For a subclass of generalized J-inner matrix valued function W the notion of associated pair is introduced and factorization formulas for W are found.
