description: We report new measurements of the decays $B\toρ^+ γ$, $B \to ρ^0 γ$ and $B \to ωγ$ using a data sample of $657 \times 10^6$ $B$ meson pairs accumulated with the Belle detector at the KEKB $e^+ e^-$ collider. We measure branching fractions ${\cal B}(B^+ \to ρ^+ γ) = (8.7^{+2.9}_{-2.7}{}^{+0.9}_{-1.1})\times 10^{-7}$, ${\cal B}(B^0 \to ρ^0 γ) = (7.8^{+1.7}_{-1.6}{}^{+0.9}_{-1.0}) \times 10^{-7}$ and ${\cal B}(B^0 \to ωγ) = (4.0^{+1.9}_{-1.7} \pm 1.3) \times 10^{-7}$. We also report the isospin asymmetry $Δ(ργ) = -0.48^{+0.21}_{-0.19}{}^{+0.08}_{-0.09}$; and the first measurement of the direct CP-violating asymmetry $A_{CP}(B^+ \to ρ^+ γ) = -0.11\pm{0.32}\pm{0.09}$, where the first and second errors are statistical and systematic, respectively.

description: We extend the bicharacter construction of quantum vertex algebras first proposed by Borcherds to the case of super Hopf algebras. We give a bicharacter description of the charged free fermion super vertex algebra, which allows us to construct different quantizations of it in the sense of $H_D$-quantum vertex algebras, or specializations to Etingof-Kazhdan quantum vertex algebras. We give formulas for the analytic continuation of product of fields, the operator product expansion and the normal ordered product in terms of the super-bicharacters.

description: We investigate how cosmic web environment impacts the average properties of central galaxies in the Sloan Digital Sky Survey (SDSS). We analyse how the average specific star-formation rate, stellar age, metallicity and element abundance ratio [$α$/Fe] of SDSS central galaxies depend on distance from the cosmic web nodes, walls and filaments identified by DisPerSE. In our approach we control for galaxy stellar mass and local density differentiated between field and group environment. Our results confirm the known trend whereby galaxies exhibit lower specific star-formation rates with decreasing distance to the cosmic web features. Furthermore, we show that centrals closer to either nodes, walls or filaments are on average older, metal richer and $α$-enhanced compared to their equal mass counterparts at larger distances. The identified property gradients appear to have the same amplitude for central galaxies in the field as for those in groups. Our findings support a cosmic web quenching that stems from nurture effects, such as ram pressure stripping and strangulation, and/or nature effects linked to the intrinsic properties of the cosmic web.

description: We present a comprehensive study of the linear response of interacting underdamped Brownian particles to simple shear flow. We collect six different routes for computing the response, two of which are based on the symmetry of the considered system and observable with respect to the shear axes. We include the extension of the Green-Kubo relation to underdamped cases, which shows two unexpected additional terms. These six computational methods are applied to investigate the relaxation of the response towards the steady state for different observables, where interesting effects due to interactions and a finite particle mass are observed. Moreover, we compare the different response relations in terms of their statistical efficiency, identifying their relative demand on experimental measurement time or computational resources in computer simulations. Finally, several measures of breakdown of linear response theory for larger shear rates are discussed.

Gaia EDR3 Reveals the Substructure and Complicated Star Formation History of the Greater Taurus-Auriga Star Forming Complex

description: The Taurus-Auriga complex is the prototypical low-mass star forming region, and provides a unique testbed of the star formation process, which left observable imprints on the spatial, kinematic, and temporal structure of its stellar population. Taurus's rich observational history has uncovered peculiarities that suggest a complicated star forming event, such as members at large distances from the molecular clouds and evidence of an age spread. With Gaia, an in-depth study of the Taurus census is possible to confirm membership, identify substructure, and reconstruct its star formation history. We have compiled an expansive census of the greater Taurus region, identifying spatial subgroups and confirming that Taurus is substructured across stellar density. There are two populations of subgroups: clustered groups near the clouds and sparse groups spread throughout the region. The sparse groups comprise Taurus's distributed population, which is on average older than the population near the clouds, and hosts sub-populations up to 15 Myr old. The ages of the clustered groups increase with distance, suggesting that the current star formation was triggered from behind. Still, the region is kinematically coherent, and its velocity structure reflects an initial turbulent spectrum similar to Larson's Law that has been modified by dynamical relaxation. Overall, Taurus has a complicated star formation history, with at least two epochs of star formation featuring both clustered and distributed modes. Given the correlations between age and spatial distribution, Taurus might be part of a galaxy-scale star forming event that can only begin to be understood in the Gaia era.

description: We investigate the structure and the tidal deformability of strange stars (SSs) with a mirror-dark-matter (MDM) core for the standard MIT bag model. We find that to explain the observations of PSR J0740+6620, PSR J0030+0451 and GW170817 simultaneously, SSs in GW170817 should have a MDM core although it is unnecessary for PSR J0740+6620 and PSR J0030+0451 to contain a MDM core. Our study leads to the result that for the standard MIT bag model, the observations of compact stars mentioned above confirm the existence of a dark-matter core inside SSs.

Vector Currents of Massive Neutrinos of an Electroweak Nature

Publisher: name: arXiv
Year: 2008
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: The mass of an electroweakly interacting neutrino consists of the electric and weak parts responsible for the existence of its charge, charge radius, and magnetic moment. Such connections explain the formation of paraneutrinos, for example, at the polarized neutrino electroweak scattering by spinless nuclei. We derive the structural equations that relate the self-components of mass to charge, charge radius, and magnetic moment of each neutrino as a consequence of unification of fermions of a definite flavor. They indicate the availability of neutrino universality and require following its logic in a constancy law dependence of the size implied from the multiplication of a weak mass of neutrino by its electric mass. According to this principle, all Dirac neutrinos of a vector nature, regardless of the difference in their masses, have the same charge, an identical charge radius, as well as an equal magnetic moment. Thereby, the possibility appears of establishing the laboratory limits of weak masses of the investigated types of neutrinos. Finding estimates show clearly that the earlier measured properties of these particles may testify in favor of the unified mass structure of their interaction with any of the corresponding types of gauge fields.

An energy-conserving dynamical model of GRB afterglows from magnetized forward and reverse shocks

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: In the dynamical models of gamma-ray burst (GRB) afterglows, the uniform assumption of the shocked region is known as provoking total energy conservation problem. In this work we consider shocks originating from magnetized ejecta, extend the energy-conserving hydrodynamical model of Yan et al. (2007) to the MHD limit by applying the magnetized jump conditions from Zhang & Kobayashi (2005). Compared with the non-conservative models, our Lorentz factor of the whole shocked region is larger by a factor $\lesssim\sqrt{2}$. The total pressure of the forward shocked region is higher than the reversed shocked region, in the relativistic regime with a factor of about 3 in our interstellar medium (ISM) cases while ejecta magnetization degree $σ<1$, and a factor of about 2.4 in the wind cases. For $σ\le 1$, the non-conservative model loses $32-42$% of its total energy for ISM cases, and for wind cases $25-38$%, which happens specifically in the forward shocked region, making the shock synchrotron emission from the forward shock less luminous than expected. Once the energy conservation problem is fixed, the late time light curves from the forward shock become nearly independent of the ejecta magnetization. The reverse shocked region doesn't suffer from the energy conservation problem since the changes of the Lorentz factor are recompensed by the changes of the shocked particle number density. The early light curves from the reverse shock are sensitive to the magnetization of the ejecta, thus are an important probe of the magnetization degree.

description: The formation of the most massive quasars observed at high redshifts requires extreme inflows of gas down to the length scales of the central compact object. Here, we estimate the maximum inflow rate allowed by gravity down to the surface of supermassive stars, the possible progenitors of these supermassive black holes. We use the continuity equation and the assumption of free-fall to derive maximum allowed inflow rates for various density profiles. We apply our approach to the mass-radius relation of rapidly accreting supermassive stars to estimate an upper limit to the accretion rates allowed during the formation of these objects. We find that the maximum allowed rate $\dot M_{\rm max}$ is given uniquely by the compactness of the accretor. For the compactness of rapidly accreting supermassive stars, $\dot M_{\rm max}$ is related to the stellar mass $M$ by a power-law $\dot M_{\rm max}\propto M^{3/4}$. The rates of atomically cooled halos (0.1 -- 10 M$_\odot$ yr$^{-1}$) are allowed as soon as $M\gtrsim1$ M$_\odot$. The largest rates expected in galaxy mergers ($10^4-10^5$ M$_\odot$ yr$^{-1}$) become accessible once the accretor is supermassive ($M\gtrsim10^4$ M$_\odot$). These results suggest that supermassive stars can accrete up to masses $>10^6$ M$_\odot$ before they collapse via the general-relativistic instability. At such masses, the collapse is expected to lead to the direct formation of a supermassive black hole even within metal-rich gas, resulting in a black hole seed that is significantly heavier than in conventional direct collapse models for atomic cooling halos.

description: We investigate a mathematical model in crop pest management, considering plant biomass, pest, and the effect of farming awareness. The pest population is divided into two compartments: susceptible pest and infected pest. We assume that the growth rate of self-aware people is proportional to the density of healthy pests present in the crop field. Impacts of awareness is modeled via a saturated term. It is further assumed that self-aware people will adopt biological control methods, namely integrated pest management. Susceptible pests are detrimental to crops and, moreover, there may be some time delay in measuring the healthy pests in the crop field. A time delay may also take place while becoming aware of the control strategies or taking necessary steps to control the pest attack. In agreement, we develop our model incorporating two time delays into the system. The existence and the stability criteria of the equilibria are obtained in terms of the basic reproduction number and time delays. Stability switches occur through Hopf-bifurcation when time delays cross critical values. Optimal control theory has been applied for the cost-effectiveness of the delayed system. Numerical simulations illustrate the obtained analytical results.

description: Considering encouraging Virbhadra's results about energy distribution of non-static spherically symmetric metrics in Kerr-Schild class, it would be interesting to study some space-times with other symmetries. Using different energy-momentum complexes, i.e. Møller, Einstein, and Tolman, in static plane-symmetric and cylindrically symmetric solutions of Einstein-Maxwell equations in 3+1 dimensions, energy (due to matter and fields including gravity) distribution is studied. Energy expressions are obtained finite and well-defined. calculations show interesting coincidences between the results obtained by Einstein and Tolamn prescriptions. Our results support the Cooperstock hypothesis about localized energy.

description: Traditionally, clustering algorithms focus on partitioning the data into groups of similar instances. The similarity objective, however, is not sufficient in applications where a fair-representation of the groups in terms of protected attributes like gender or race, is required for each cluster. Moreover, in many applications, to make the clusters useful for the end-user, a balanced cardinality among the clusters is required. Our motivation comes from the education domain where studies indicate that students might learn better in diverse student groups and of course groups of similar cardinality are more practical e.g., for group assignments. To this end, we introduce the fair-capacitated clustering problem that partitions the data into clusters of similar instances while ensuring cluster fairness and balancing cluster cardinalities. We propose a two-step solution to the problem: i) we rely on fairlets to generate minimal sets that satisfy the fair constraint and ii) we propose two approaches, namely hierarchical clustering and partitioning-based clustering, to obtain the fair-capacitated clustering. The hierarchical approach embeds the additional cardinality requirements during the merging step while the partitioning-based one alters the assignment step using a knapsack problem formulation to satisfy the additional requirements. Our experiments on four educational datasets show that our approaches deliver well-balanced clusters in terms of both fairness and cardinality while maintaining a good clustering quality.

uGMRT observations of a Fast and Blue Optical Transient -- AT 2018cow

description: We present low-frequency radio observations of a fast-rising blue optical transient (FBOT), AT\,2018cow, with the upgraded Giant Metrewave Radio Telescope (uGMRT). Our observations span $t =$ 11 $-$ 570 days post-explosion and a frequency range of 250 $-$ 1450 MHz. The uGMRT light curves are best modeled as synchrotron emission from an inhomogeneous radio-emitting region expanding into an ionized medium. However, due to the lack of information on the source covering factor, which is a measure of the degree of inhomogeneity, we derive various parameters assuming the source covering factor to be unity. These parameters, hence, indicate limits on the actual values in an inhomogeneous model. We derive the lower limit of the shock radius to be $R \sim$ (6.1$-$14.4) $\times$ 10$^{16}$ cm at $t =$ 138$-$257 days post-explosion. We find that the fast-moving ejecta from the explosion are moving with velocity $v$ $>$ 0.2c up to $t =$ 257 days post-explosion. The upper limits of the mass-loss rate of the progenitor are $\dot{M}$ $\sim$ (4.1$-$1.7) $\times$ 10$^{-6}$ $M_{\odot}$\,yr$^{-1}$ at (19.3$-$45.7) years before the explosion for a wind velocity $v_{\rm w}$ = 1000 km\,s$^{-1}$. These $\dot{M}$ values are $\sim$ 100 times smaller than the previously reported mass-loss rate at 2.2 years before the explosion, indicating an enhanced phase of the mass-loss event close to the end-of-life of the progenitor. Our results are in line with the speculation of the presence of a dense circumstellar shell in the vicinity of AT\,2018cow from previous radio, ultra-violet, and optical observations.

description: We introduce a hierarchical classification of theories that describe systems with fundamentally limited information content. This property is introduced in an operational way and gives rise to the existence of mutually complementary measurements, i.e. a complete knowledge of future outcome in one measurement is at the expense of complete uncertainty in the others. This is characteristic feature of the theories and they can be ordered according to the number of mutually complementary measurements which is also shown to define their computational abilities. In the theories multipartite states may contain entanglement and tomography with local measurements is possible. The classification includes both classical and quantum theory and also generalized probabilistic theories with higher number of degrees of freedom, for which operational meaning is given. We also discuss thought experiments discriminating standard quantum theory from the generalizations.

Factor shares in the Canadian forest industries, 1957-84
Creators: name: Singh, Ramvir
Publisher: name: University of British Columbia
Year: 2010

description: This study has investigated time-series data from 1957 to 1984 in order to describe the existing functional income distribution and trends in the Canadian forest industries and its constituent sectors viz. logging industry (SIC 04), wood industries (SIC 25), and paper & allied industries (SIC 27). The functional income distribution in these industries has been measured by relative shares of factor inputs: labour, durable capital, money capital, materials, energy, taxes, and entrepreneurship. The study has followed a methodology based on an income accounting approach according to which factor incomes were determined on a realization basis. This approach stresses the cost sharing nature of the resulting relative factor shares. The emphasis is on the long-term trends of relative factor shares, real factor prices, and factor productivities, so that the competitiveness of the industries in the use of various factor inputs was discussed. The principal hypothesis of this study is that: relative factor shares in the forest industries have changed and that the rate of change in a relative factor share is consistent with the difference between the rate of change in real factor price and factor productivity. That is, the observed rate of change in a relative factor share is consistent with the hypothesized rate of change. The results support the principal hypothesis. There is only one exception, that is the observed rate of change in the relative share of stumpage is not consistent with the hypothesized rate of change. In the forest industries, the relative shares of labour, stumpage, taxes, and profit have declined; and those of durable capital, money capital, materials, and energy have increased. Real labour price has substantially increased, while real materials' price has not significantly changed. These and other changes have encouraged technologies which are labour and timber saving, and capital, energy and materials using. As a result, labour productivity and timber productivity have risen, and productivities of other factor inputs have declined. Trends in various variables in the constitutent sectors differ in some cases from the ones for the forest industries in aggregate. The resulting functional income distribution in the Canadian forest industries has been compared with that in the Canadian manufacturing sector and the Finnish forest industries. The directions of change in the relative factor shares, real factor prices, and factor productivities in the forest industries are in general agreement with thsoe in the Canadian manufacturing sector. However, functional income distribution in the Finnish forest industries has been found to be different from that in the Canadian forest industries. Finally, some policy implications of the findings of this study have been suggested and some areas for further research identified.

description: The age-metallicity relation is a fundamental tool for constraining the chemical evolution of the Galactic disc. In this work we analyse the observational properties of this relation using binary stars that have not interacted consisting of a white dwarf - from which we can derive the total age of the system - and a main sequence star - from which we can derive the metallicity as traced by the [Fe/H] abundances. Our sample consists of 46 widely separated, but unresolved spectroscopic binaries identified within the Sloan Digital Sky Survey, and 189 white dwarf plus main sequence common proper motion pairs identified within the second data release of Gaia. This is currently the largest white dwarf sample for which the metallicity of their progenitors have been determined. We find a flat age-metallicity relation displaying a scatter of [Fe/H] abundances of approximately 0.5 dex around the solar metallicity at all ages. This independently confirms the lack of correlation between age and metallicity in the solar neighbourhood that is found in previous studies focused on analysing single main sequence stars and open clusters.

description: We study the phase diagram of a quasi-two dimensional magnetic system ${\rm Rb_2MnF_4}$ with Monte Carlo simulations of a classical Heisenberg spin Hamiltonian which includes the dipolar interactions between ${\rm Mn}^{2+}$ spins. Our simulations reveal an Ising-like antiferromagnetic phase at low magnetic fields and an XY phase at high magnetic fields. The boundary between Ising and XY phases is analyzed with a recently proposed finite size scaling technique and found to be consistent with a bicritical point at T=0. We discuss the computational techniques used to handle the weak dipolar interaction and the difference between our phase diagram and the experimental results.

Three Essays in Economics of Gender
Creators: name: Jahanshahi, Babak <1981>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2014
Subjects: SECS-P/01 Economia politica

description: During recent decades, economists' interest in gender-related issues has risen. Researchers aim to show how economic theory can be applied to gender related topics such as peer effect, labor market outcomes, and education. This dissertation aims to contribute to our understandings of the interaction, inequality and sources of differences across genders, and it consists of three empirical papers in the research area of gender economics.
The aim of the first paper ("Separating gender composition effect from peer effects in education") is to demonstrate the importance of considering endogenous peer effects in order to identify gender composition effect. This fact is analytically illustrated by employing Manski's (1993) linear-in-means model. The paper derives an innovative solution to the simultaneous identification of endogenous and exogenous peer effects: gender composition effect of interest is estimated from auxiliary reduced-form estimates after identifying the endogenous peer effect by using Graham (2008) variance restriction method. The paper applies this methodology to two different data sets from American and Italian schools.
The motivation of the second paper ("Gender differences in vulnerability to an economic crisis") is to analyze the different effect of recent economic crisis on the labor market outcome of men and women. Using triple differences method (before-after crisis, harder-milder hit sectors, men-women) the paper used British data at the occupation level and shows that men suffer more than women in terms of probability of losing their job. Several explanations for the findings are proposed.
The third paper ("Gender gap in educational outcome") is concerned with a controversial academic debate on the existence, degree and origin of the gender gap in test scores. The existence of a gap both in mean scores and the variability around the mean is documented and analyzed. The origins of the gap are investigated by looking at wide range of possible explanations.

description: Micro‐ and nanopatterning of proteins on surfaces allows to develop for example high‐throughput biosensors in biomedical diagnostics and in general advances the understanding of cell‐material interactions in tissue engineering. Today, many techniques are available to generate protein pattern, ranging from technically simple ones, such as micro‐contact printing, to highly tunable optical lithography or even technically sophisticated scanning probe lithography. Here, one focus is on the progress made in the development of protein‐based materials as positive or negative photoresists allowing micro‐ to nanostructured scaffolds for biocompatible photonic, electronic and tissue engineering applications. The second one is on approaches, which allow a controlled spatiotemporal positioning of a single protein on surfaces, enabled by the recent developments in immobilization techniques coherent with the sensitive nature of proteins, defined protein orientation and maintenance of the protein activity at interfaces. The third one is on progress in photolithography‐based methods, which allow to control the formation of protein‐repellant/adhesive polymer brushes.

description: X-ray bursts have recently been discovered in the Cepheids $δ$ Cep and $β$ Dor modulated by the pulsation cycle. We have obtained an observation of the Cepheid $η$ Aql with the XMM-Newton satellite at the phase of maximum radius, the phase at which there is a burst of X-rays in $δ$ Cep. No X-rays were seen from the Cepheid $η$ Aql at this phase, and the implications for Cepheid upper atmospheres are discussed. We have also used the combination of X-ray sources and Gaia and 2MASS data to search for a possible grouping around the young intermediate mass Cepheid. No indication of such a group was found.

description: In this work, we consider the canonical charmonium assignments for Y(4360) and Y(4660). Y(4660) is good candidate of $\rm 5 ^3S_1$ $c\bar{c}$ state, the possibility of Y(4360) as a $\rm 3 ^3D_1$ $c\bar{c}$ state is studied, and the charmonium hybrid interpretation of Y(4360) can not be excluded completely. We evaluate the $e^{+}e^{-}$ leptonic widths, E1 transitions, M1 transitions and the open flavor strong decays of Y(4360) and Y(4660). Experimental tests for the charmonium assignments are suggested.

description: We study photon orbits in the background of $(1+3)$-dimensional static, spherically symmetric geometries. In particular, we have obtained exact analytical solutions to the null geodesic equations for light rays in terms of the Weierstraß function for space-times arising in the context of scale-dependent gravity. The trajectories in the $(x-y)$ plane are shown graphically, and we make a comparison with similar geometries arising in different contexts. The light deflection angle is computed as a function of the running parameter $ξ$, and an upper bound for the latter is obtained.

Aspects of Eucalyptus waferboard
Creators: name: Ngusya, Musyoka
Publisher: name: University of British Columbia
Year: 2010

description: Eucalyptus species is already well established in the pulp and paper industry. The species noted fast growth, especially in the tropical regions, provides a special resource for utilization in providing shelter in these regions, which have some of the highest growth in population rates. Waferboard industry, though well established in most developed countries, is rare in most developing countries. The fact that waferboard requires relatively low quality wood, as opposed to plywood, is an important factor and makes it more appealing for development in these regions. Technical information on utilization of Eucalyptus for waferboard is lacking in most aspects, and most of the experimentation has mainly been conducted on preliminary levels only. The study was carried out to fill that gap and provide data which can lead to increased utilization of the species in the waferboard industry. This was achieved by the making of panels under standard conditions and performing standard tests on the specimens cut from the laboratory made panels.
title: Die Anwendung des Modells „Komplexitätsstufen von aktivierenden Lernressourcen“ auf die Förderung von Informationskompetenz in deutschen Hochschulbibliotheken
Creators: name: Schlottke, Natalie
Publisher: name: Hochschule Hannover

Subjects: subject: 020 Bibliotheks- und Informationswissenschaft

description: Das Stufenmodell „Komplexitätsstufen von aktivierenden Lernressourcen“ wurde von einem Projektteam der Fachhochschule Hannover für die Produktion von E-Learning Materialien entwickelt. Die Bachelorarbeit soll beantworten, ob das Modell in der Praxis anwendbar ist. Hierfür wird eine Analyse des Stufenmodells angestrebt. Um die Anwendbarkeit zu überprüfen, wird das Stufenmodell mit Beispielen aus wissenschaftlichen Bibliotheken abgeglichen. Die Beispiele basieren auf Lernressourcen, die aus Bibliotheken entnommen werden, die mittels E-Learning Informationskompetenz vermitteln. Für die Analyse werden die Angebote anhand der Parameter und der Lernziele des Stufenmodells kategorisiert. Um die Ergebnisse anwendbar zu machen, wird weiterhin ein Konzept für die Förderung von Informationskompetenz mit E-Learning Werkzeugen vorgeschlagen. Die Analyse des Stufenmodells zeigt auf, dass das Modell eine gute Orientierung ist, um E-Learning Ressourcen zu kategorisieren. Der Parameter Komplexität eignet sich, um die Ressourcen umfassend abzubilden, da die meisten Beispiele in das Modell einsortiert werden können. Der Schwachpunkt des Modells besteht jedoch darin, dass zu viele Parameter berücksichtigt werden, die sich gegenseitig ausschließen können. Die Ergebnisse der Analyse werden abschließend zu einem Konzept für Bibliotheken zusammengefasst. Die Theorien der Didaktik, sowie das Schwellenkonzept der Association of College & Research Libraries dienen hierbei als Grundlage. Dies zeigt auf, dass Informationskompetenz mit E-Learning Werkzeugen vermittelt werden und das Stufenmodell als Instrument dienlich sein kann.
A field theoretic approach to master equations and a variational method beyond the Poisson ansatz
Creators: name: Ohkubo, Jun
Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We develop a variational scheme in a field theoretic approach to a stochastic process. While various stochastic processes can be expressed using master equations, in general it is difficult to solve the master equations exactly, and it is also hard to solve the master equations numerically because of the curse of dimensionality. The field theoretic approach has been used in order to study such complicated master equations, and the variational scheme achieves tremendous reduction in the dimensionality of master equations. For the variational method, only the Poisson ansatz has been used, in which one restricts the variational function to a Poisson distribution. Hence, one has dealt with only restricted fluctuation effects. We develop the variational method further, which enables us to treat an arbitrary variational function. It is shown that the variational scheme developed gives a quantitatively good approximation for master equations which describe a stochastic gene regulatory network.
