The solar spectrum of light incident on the solar cell would affect its output per time. It is reported that some geographical locations are exposed to harsh solar radiation that has resulted to reduced lifespan and performance of Photovoltaic (PV) panels. In this research, the spectral filtering was first carried-out in the dark room and then a bio-filter material was synthesized to serve as filter in a live experiment. The bio-optical material was copper coated ixora-methanol extract. The results reveal that the biofilter were effective and had the potential to stabilize the measured parameter. Further research was recommended.

Though this genus consists of around 500 species, despite its phytoconstituent potentiality, only a few species such as Ixora chinensis, I. lutea, and I. parviflora (Akter et al, 2015) are being cultivated, studied, and utilized (Kharat et al, 2013).…”

The functional attributes of any plants are mainly due to the presence of a major class of secondary metabolites, phenolic acids, and flavonoids, but other organic and inorganic compounds like coumarins and antioxidant micronutrients (Cu, Mn, Zn) also have a major influence on well-being (Kumar, Arya et al., 2020;Repetto & Llesuy, 2002). The preliminary steps to utilize plant sources are screening and characterization of these bioactive compounds (Sasidharan et al., 2011). India is one of the world's biodiversity hotspots, and there are many lesser-known or underutilized plants that are used both medicinally and as diet sources but are limited to cultivation and consumption by locals (Nandal & Bhardwaj, 2014). Ixora coccinea in the Rubiaceae family is one such plant with

In[26], the analytical expressions of the Wigner function of the EBSs have been derived. Substituting them into equation (4) as the initial conditions and numerically solving this partial differential equation, one can obtain the time-evolving Wigner function.…”

The mean parity (the Wigner function at the origin) of excited binomial states, excited coherent states and excited thermal states in thermal environments is investigated in details. It is found that the single-photon excited binomial state and the single-photon excited coherent state exhibit certain similarity in the aspect of their mean parity in the thermal environment. We show the negative mean parity can be regarded as an indicator of nonclassicality of single-photon excitation of optical fields with a little coherence, especially for the single-photon excited thermal states.PACS numbers: 42.50.Dv, 03.65.Yz, 05.40.CaAmong various kinds of indicators of nonclassicality of optical fields [1][2][3][4], the partial negativity of the Wigner function (PNWF) indicates the highly nonclassical character of the optical fields. Quantum excitation of general optical fields can always exhibit PNWF which will be destroyed and eventually completely disappear at the same decay time γt c = ln 2+2n 1+2n in a thermal environment [5]. The Wigner function W (q, p) is proportional to the expectation value of the parity operator that performs reflections about the phase-space point (q, p) [6]. For an optical field in the state ρ, the value of Wigner function at the origin of the state can be derived by [7,8] whereÔ e ≡ ∞ k=0 |2k 2k| andÔ o ≡ ∞ k=0 |2k + 1 2k + 1| are the even and odd parity operators respectively. Therefore, the value of Wigner function at the origin equals the constant 2 π times the expectation value of parity operator for the state ρ. Hereafter the expectation value of parity operator is named as "mean parity".There have been several kinds of experimental schemes for reconstructing or measuring the Wigner distribution of the optical fields or the motional states of trapped atoms [9,10]. Here, we briefly outline an operational approach for measuring the Wigner function which is based on the Fresnel transformation of measured Rabi oscillations [11]. Assuming a two-level atom (qubit) initially in the excited state |e is resonantly coupled with the field prepared in the quantum state of interest whose dynamical behavior is governed by the Jaynes-Cummings model in the interaction picture λ(a † σ − + aσ + ). Via observing Rabi oscillations of the two-level atom, the mean parity of the initial state of interest can be derived as follows:where P g (τ ) (P e (τ )) is the probability of finding the atom in the ground state |g (the excited state |e ) as a function of dimensionless interaction time τ = λt. Obviously, P g (τ ) − P e (τ ) can be regarded as the mean parity of the two-level atom. Thus, the initial mean parity of an optical field is directly related to the Fresnel integral of the mean parity of a resonant coupled two-level atom. Though the mean parity of a quantum field contains less information than its full Wigner function, it can partly determine the dynamical behaviors of Rabi oscillation of the resonant coupled qubit, which is important in those quantum information processes containing the resonant couplin...
