Holographic dark energy through Kaniadakis entropy in non flat universe

By extending the standard holographic principle to a cosmological framework and combining the non-flat condition with the Kaniadakis entropy, we construct the non-flat Kaniadakis holographic dark energy model. The model employs Kaniadakis parameter $K$ and a parameter $c$. Derivation of the differential equation for KHDE density parameter to describe the evolutionary behavior of the universe is obtained. Such a differential equation could explain both the open as well as closed universe models. The classification based on matter and dark energy (DE) dominated regimes show that the KHDE scenario may be used to specify the Universe's thermal history and that a quintom regime can be encountered. For open and closed both the cases, we find the expressions for the deceleration parameter and the equation of state (EoS) parameter. Also, by varying the associated parameters, classical stability of the method is established. On considering the curvature to be positive, the universe favors the quintom behavior for substantially smaller values as opposed to the flat condition, when only quintessence is attained for such $K$ values. Additionally, we see a similar behavior while considering the curvature to be negative for such $K$ values. Therefore, adding a little bit of spatial geometry that isn't flat to the KHDE enhances the phenomenology while maintaining $K$ values at lower levels. To validate the model parameters, the most recent $30\;H(z)$ dataset measurements, in the redshift range $0.07 \leq z \leq 1.965$ are utilized. In addition, the distance modulus measurement from the current Union 2.1 data set of type Ia supernovae are employed.Comment: 17 pages, 12 figure

Allelopathy effect of aqueous extract of Clerodendrum viscosum, Ageratum conyzoides and Parthenium hysterophorus on the seed germination and seedling vigour of Chickpea seeds (Cicer arietinum L.) in vitro

In present study the allelopathic effect of aqueous leaf extracts of Clerodendrum viscosum, Ageratum conyzoides and Parthenium hysterophorus was observed on the seed germination of Chickpea in vitro (Cicer arietinum.L.).Seed germination was found to be inhibited in all the leaf extract concentrations used i.e. 2%,4%,6%,8% and 10%. However higher inhibition was observed in the 10% leaf extract of the test plants (i.e. Cl. viscosum, Ag. conyzoides and P. hysterophorus). In compare to all allelopathic plants extracts more inhibition was found in P. hysterophorus leaf extract followed by Cl. viscosum and Ag. conyzoides. Higher inhibition of radical and plumule growth of the Chickpea seeds was found with the increase in concentration of the leaf extracts used. Percentage of germination of Chickpea seeds was found to be low in 10% concentration whereas in untreated seeds it was found to be more

Systematic analysis of Quercetin and its derivatives with Special Reference to anti-inflammatory property-Based on Network Pharmacology

The clinical success of phyto-chemicals and computationally assisted drug discovery-derived agents has stimulated the development of novel compounds for human illnesses. In the field of anticancer drug discovery, rational investigation has sped up the process. Quercetin and its derivatives have a long history of anti-inflammatory efficacy in pomegranate and other natural products, according to scientific evidence. Small structural alterations, for example, can drastically affect cell death behaviour and trigger inflammation, making it difficult to unravel the structure-activity relationship. As a result, our objective is to use a rational drug discovery approach to develop a mechanistic approach for quercetin and its derivatives, which will be compared to market anti-inflammatory medications utilising in-silico tools. Using the software Cytoscape, we created pharmacology networks of inflammatory proteins based on data acquired from several databases. The networks show how bioactives interact with molecular targets and how they relate to illnesses, particularly inflammation. Quercetin's network pharmacology study has shown novel connections between bioactive targets and possible inflammatory aetiology applications. The future prospect is to understand these chemicals in vitro and in vivo

Modeling a IF double sampling bandpass switched capacitor ΣΔ ADC with a symmetric noise transfer function for WiMAX/WLAN

4G technology aims to revolutionize private and professional communication with its ubiquity and high-speed transmission (averaging 100Mbps). WiMAX and WLAN are two of the high speed access technologies to be used in the 4G mobile communication. Apropos to their high bandwidths, oversampling converters, e.g.ΣΔ ADCs, used for these standards would entail high levels of power consumption. Double sampling technique used in ΣΔ ADCs help in reducing the power consumption, since the actual sampling rate is only half the sampling frequency required to achieve a target resolution. But for conventional modulators, with low pass noise transfer functions (NTF), this benefit is hampered by the introduction of folded noise due to the mismatch of sampling capacitances. This paper presents a novel method of designing IF bandpass switched capacitor (SC)ΣΔ modulators with symmetric NTFs. Such a bandpass NTF is formulated with its center frequency at one-fourth the effective sampling frequency. The symmetricity ensures that the folded noise is `noise-shaped' along with the quantization noise. The idea is verified with a discrete time bandpass ΣΔ modulator modeled using Simulink®, including various nonlinearities, viz. clock jitter, opampnonidealities, and capacitive mismatch effects owing to double sampling and use of a multibitquantizer. Behavioral simulations of the proposed non-ideal model for WiMAX and WLAN, with a bandwith of 10MHz and 11MHz, respectively, achieved a peak resolution greater than 10 bits for each of the standards

Numerical modelling of dissipation energy of high tensile steel frames against cyclic earthquake excitations

The design of steel structures for ductile response requires (a) materialductility, (b) cross section and member ductility, and (c) structural ductility. Dissipating the earthquake input energy by means of plastic excursions has to be compatible with the plastic deformation capacity of the structure. This work concerns incremental approach of modeling for elastoplastic analysis of structural members subjected to harmonically varying severe earthquake loads and their parametric responses over a range of applied frequencies and amplitudes. Investigations have been carried out in respect of stable and reliable hysteretic energy dissipation mechanisms of high rise steel structures against typical time-history loading of four hypothetical frequencies. Eigen-buckling responses for high rise steel structures subjected to earthquake forces are derived using general purpose software (STAAD). Finally critical structural component is identified for the high rise steel structure for estimation of available in-elastic dissipation energy from material ductility against earthquake excitations. The novelty allows for a very useful generalized formulation for the basic analysis procedures adopted in non-linear material problems. All essential features of a non-linear finite element solution are described in relation to one dimensional model for elasto-plastic beam bending. Solutions techniques are programmed in FORTRAN 90 for Newton-Raphson iteration for non-linear finite element analysis to derive hysteretic energy dissipation of high rise steel structures
