Novel research methods to evaluate renewable energy investment and environment: evidence from global data

The global economy is facing a severe threat of global warming and climate change, where the primary cause of these issues is regarded as the carbon dioxide emissions. To eradicate such issues, this study tends to explore the global energy use, economic growth, renewable electricity and carbon emission throughout 1990 – 2020. Using various time-series econometric specifications, this study validates the stationarity of all these variables for the long-run estimations. Besides, this study detects the issue of data non-normality, due to which this study opted the novel and efficient quantile-on-quantile regression. The estimated outcomes asserted that energy use and economic growth significantly and severely enhance global carbon emissions at higher quantiles, whereas the magnitude of the influence is found weaker in the lower and lower-middle quantiles, thus validating energy use and economic growth as the factors of increased environmental degradation. On the contrary, renewable electricity significantly reduces the carbon emissions level only in the lower as and middle quantile, while the influence non-negative at the higher quantiles. This study recommends the use of renewable energy, increase renewable ’ s investment, research and development, adoption energy efficient approaches to reduce fossil energy.
LOCAL GROUP DWARF ELLIPTICAL GALAXIES. II. STELLAR KINEMATICS TO LARGE RADII IN NGC 147 AND NGC 185

We present kinematic and metallicity profiles for the M 31 dwarf elliptical (dE) satellite galaxies NGC 147 and NGC 185. The profiles represent the most extensive spectroscopic radial coverage for any dE galaxy, extending to a projected distance of 8 half-light radii (8reff ∼ 14′). We achieve this coverage via Keck/DEIMOS multislit spectroscopic observations of 520 and 442 member red giant branch stars in NGC 147 and NGC 185, respectively. In contrast to previous studies, we find that both dEs have significant internal rotation. We measure a maximum rotational velocity of 17 ± 2 km s−1 for NGC 147 and 15 ± 5 km s−1 for NGC 185. While both rotation profiles suggest a flattening in the outer regions, there is no indication that we have reached the radius of maximum rotation velocity. The velocity dispersions decrease gently with radius with average dispersions of 16 ± 1 km s−1 and 24 ± 1 km s−1 for NGC 147 and NGC 185, respectively. The average metallicities for NGC 147 and NGC 185 are [Fe/H] = −1.1 ± 0.1 and [Fe/H] = −1.3 ± 0.1, respectively; both dEs have internal metallicity dispersions of 0.5 dex, but show no evidence for a radial metallicity gradient. We construct two-integral axisymmetric dynamical models and find that the observed kinematical profiles cannot be explained without modest amounts of non-baryonic dark matter. We measure central mass-to-light ratios of M/LV = 4.2 ± 0.6 and M/LV = 4.6 ± 0.6 for NGC 147 and NGC 185, respectively. Both dE galaxies are consistent with being primarily flattened by their rotational motions, although some anisotropic velocity dispersion is needed to fully explain their observed shapes. The velocity profiles of all three Local Group dEs (NGC 147, NGC 185, and NGC 205) suggest that rotation is more prevalent in the dE galaxy class than previously assumed, but often manifests only at several times the effective radius. Since all dEs outside the Local Group have been probed to only inside the effective radius, this opens the door for formation mechanisms in which dEs are transformed or stripped versions of gas-rich rotating progenitor galaxies.
A central compact object in Kes 79: the hypercritical regime and neutrino expectation

We present magnetohydrodynamical simulations of a strong accretion onto magnetized proto-neutron stars for the Kesteven 79 (Kes 79) scenario. The supernova remnant Kes 79, observed with the Chandra ACIS-I instrument during approximately 8.3 h, is located in the constellation Aquila at a distance of 7.1 kpc in the galactic plane. It is a galactic and a very young object with an estimate age of 6 kyr. The Chandra image has revealed, for the first time, a point-like source at the center of the remnant. The Kes 79 compact remnant belongs to a special class of objects, the so-called Central Compact Objects, which exhibits no evidence for a surrounding pulsar wind nebula. In this work we show that the submergence of the magnetic field during the hypercritical phase can explain such behavior for Kes 79 and others CCOs. The simulations of such regime were carried out with the adaptive-mesh-refinement code FLASH in two spatial dimensions, including radiative loss by neutrinos and an adequate equation of state for such regime. From the simulations, we estimate that the number of thermal neutrinos expected on the Hyper-Kamiokande Experiment is 733$\pm$364. In addition, we compute the flavor ratio on Earth for a progenitor model.
Investigation of propagation characteristics of laser light and squeezed light in fog

There is a great deal of interest in highly sensitive sensing technology that utilizes the quantum entanglement of quantum light. Light wave sensing based on the quantum illumination theory is expected to be used outdoors with atmospheric disturbances. For the realization of such technology, it is extremely important to know the fundamental properties of quantum light propagation under various atmospheric conditions. In this study, we first investigated the propagation characteristics of laser light in fog. Next, we investigated the effects of fog on the quantum properties of single-mode squeezed light. It was found that when the fog density increases, not only the light energy is attenuated, but also the noise is superimposed on the intensity distribution. It was also found that the effect of fog on the squeezed light is mainly energy attenuation.
The MBH-M* relation for X-ray-obscured, red QSOs at 1.2 < z < 2.6

We present near-infrared spectra, obtained with SINFONI and XShooter observations at ESO VLT, of nine dusty, red QSOs at 1.2 10^{21} - 10^{22} cm^{-2}) and show a broad Ha component in the NIR spectra. We complement this sample with twelve additional sources taken from the literature with similar properties resulting in a total sample of 21 X-ray obscured, intermediate type (1.8-1.9), dusty reddened QSOs. From the broad Ha line we have computed the BH masses through the virial formula and derived Eddington ratios. Moreover, from optical/IR multi-component SED fitting we have derived the stellar mass of their host galaxies and their SFRs. We find that most of the sources in our sample are hosted in starburst and main sequence star-forming galaxies with Eddington ratios lambda>0.1. We find a strong trend with the BH mass i.e. less massive objects are scattered below and above the local relation while the most massive ones are mainly located above it. We also studied the evolution of these sources on the M_BH-M_star plane compared to a sample of optically blue type--1 QSOs and we find that obscured red QSOs show a ratio of M_BH to M_star that increases with redshift which is consistent with or slightly lower than what has been found for blue QSOs. These sources may represent the blow-out phase at the end of the rapid BH growth and immediately preceding the classical blue QSOs typically sampled in optical surveys. They in fact show evidence of outflows in the ionized gas component, but their BH has already fully formed.
Cancer and Vascular Comorbidity Effects on Dementia Risk and Neuropathology in the Oldest-Old

Background: Dementia, vascular disease, and cancer increase with age, enabling complex comorbid interactions. Understanding vascular and cancer contributions to dementia risk and neuropathology in oldest-old may improve risk modification and outcomes. Objective: Investigate the contributions of vascular factors and cancer to dementia and neuropathology. Methods: Longitudinal clinicopathologic study of prospectively followed Mayo Clinic participants dying≥95 years-old who underwent autopsy. Participants were stratified by dementia status and compared according to demographics, vascular risk factors, cancer, and neuropathology. Results: Participants (n = 161; 83% female; 99% non-Hispanic whites)≥95 years (95–106 years-old) with/without dementia did not differ based on demographics. APOE ɛ2 frequency was higher in no dementia (20/72 [28%]) versus dementia (11/88 [12%]; p = 0.03), but APOE ɛ4 frequency did not differ. Coronary artery disease was more frequent in no dementia (31/72 [43%]) versus dementia (23/89 [26%]; p = 0.03) associated with 56% lower dementia odds (odds ratio [OR] = 0.44 [confidence interval (CI) = 0.19–0.98]; p = 0.04) and fewer neuritic/diffuse plaques. Diabetes had an 8-fold increase in dementia odds (OR = 8.42 [CI = 1.39–163]; p = 0.02). Diabetes associated with higher cerebrovascular disease (Dickson score; p = 0.05). Cancer associated with 63% lower dementia odds (OR = 0.37 [CI = 0.17–0.78]; p < 0.01) and lower Braak stage (p = 0.01). Conclusion: Cancer exposure in the oldest-old was associated with lower odds of dementia and tangle pathology, whereas history of coronary artery disease was associated with lower odds of dementia and amyloid-β plaque pathology. History of diabetes mellitus was associated with increased odds of dementia and cerebrovascular disease pathology. Cancer-related mechanisms and vascular risk factor reduction strategies may alter dementia risk and neuropathology in oldest-old.
NEAR-INFRARED SPECTRA AND INTRINSIC LUMINOSITIES OF CANDIDATE TYPE II QUASARS AT 2 < z < 3.4

We present JHK near-infrared (NIR) spectroscopy of 25 candidate Type II quasars selected from the Sloan Digital Sky Survey (SDSS), using Triplespec on the Apache Point Observatory 3.5 m telescope, the Folded-port InfraRed Echellette at the Magellan/Baade 6.5 m telescope, and the Gemini Near-Infrared Spectrograph on Gemini. At redshifts of 2 < z < 3.4, our NIR spectra probe the rest-frame optical region of these targets, which were initially selected to have strong lines of C iv and Ly α, with FWHM < 2000 km s−1 from the SDSS pipeline. We use the [O iii] λ5007 line shape as a model for the narrow-line region emission and find that Hα consistently requires a broad component with FWHMs ranging from 1000 to 7500 km s−1. Interestingly, the C iv lines also require broad bases, but with considerably narrower widths of 1000–4500 km s−1. Estimating the extinction using the Balmer decrement and also the relationship in lower-z quasars between rest equivalent width and luminosity in the [O iii] line, we find typical AV values of 0–2 mag, which naturally explains the attenuated C iv lines relative to Hα. We propose that our targets are moderately obscured quasars. We also describe one unusual object with three distinct velocity peaks in its [O iii] spectrum.
Sociocultural and economic significance in the harvest of the pitaya sahuira (Stenocereus montanus) in Sinaloa, Mexico

Pitayas (Stenocereus spp.) are one of the most important wild plants in Mexico; however, there are few studies that evaluate the harvest value and commercialization of local species. This research records the sociocultural and economic importance of the harvest of pitaya sahuira (Stenocereus montanus) in two localities of the state of Sinaloa, Mexico: 1) San José del Llano, Badiraguato, and 2) several small communities in the municipality of Choix. Semi-structured surveys and participatory evaluation were carried out with different people who harvest and market the pitaya fruits during the production season to document the harvest method, productivity, commercial value, fruit destination, cultural perceptions, and the differences between both regions. In both localities, daily harvests are made, and it constitutes the main economic activity during the production season, about 40 to 50 days between May and July. In San José, the harvest is carried out by men and women, while in Choix, it is practically exclusive by men. Higher productivity was recorded in San José, reflected by a greater amount of daily fruit harvested in a workday; however, in Choix, the fruit has a higher sales value, which balances the estimated annual earnings of around 1,940 dollars per harvester (~40,000.00 Mexican pesos). Given its great commercial value, it is necessary to implement cultivation and domestication strategies at the local level, as a regional economic alternative and to reduce the pressure on native populations. This work incorporates additional evidence on the great cultural and economic importance of the genus Stenocereus in Mexico and motivates the design of better strategies for sustainable use and the revaluation of this biocultural heritage.
Holographic fluid from the nonminimally coupled scalar–tensor theory of gravity

We establish the gravity/fluid correspondence in the nonminimally coupled scalar–tensor theory of gravity. Imposing the Petrov type I boundary condition over the gravitational field, we find that, for a certain class of background metrics, the boundary fluctuations obey the standard Navier–Stokes equation for an incompressible fluid without any external force term in the leading order approximation under the near horizon expansion. That is to say, the scalar field fluctuations do not contribute in the leading order approximation regardless of what kind of boundary condition we impose on it.
The spectrum of Volterra operators on weighted spaces of entire functions

We investigate the spectrum of the Volterra operator $V_g$ with symbol an entire function $g$, when it acts on weighted Banach spaces $H_v^{\infty}(\mathbb{C})$ of entire functions with sup-norms and when it acts on H\"ormander algebras $A_p$ or $A^0_p$.
Mixing graph colourings

This thesis investigates some problems related to graph colouring, or, more precisely, graph re-colouring. Informally, the basic question addressed can be phrased as follows. Suppose one is given a graph G whose vertices can be properly k-coloured, for some k ≥ 2. Is it possible to transform any k-colouring of G into any other by recolouring vertices of G one at a time, making sure a proper k-colouring of G is always maintained? If the answer is in the affirmative, G is said to be k-mixing. The related problem of deciding whether, given two k-colourings of G, it is possible to transform one into the other by recolouring vertices one at a time, always maintaining a proper k-colouring of G, is also considered. These questions can be considered as having a bearing on certain mathematical and ‘real-world’ problems. In particular, being able to recolour any colouring of a given graph to any other colouring is a necessary pre-requisite for the method of sampling colourings known as Glauber dynamics. The results presented in this thesis may also find application in the context of frequency reassignment: given that the problem of assigning radio frequencies in a wireless communications network is often modelled as a graph colouring problem, the task of re-assigning frequencies in such a network can be thought of as a graph recolouring problem. Throughout the thesis, the emphasis is on the algorithmic aspects and the computational complexity of the questions described above. In other words, how easily, in terms of computational resources used, can they be answered? Strong results are obtained for the k = 3 case of the first question, where a characterisation theorem for 3-mixing graphs is given. For the second question, a dichotomy theorem for the complexity of the problem is proved: the problem is solvable in polynomial time for k ≤ 3 and PSPACE-complete for k ≥ 4. In addition, the possible length of a shortest sequence of recolourings between two colourings is investigated, and an interesting connection between the tractability of the problem and its underlying structure is established. Some variants of the above problems are also explored.
CHARACTERIZING TWO SOLAR-TYPE KEPLER SUBGIANTS WITH ASTEROSEISMOLOGY: KIC 10920273 AND KIC 11395018

Determining fundamental properties of stars through stellar modeling has improved substantially due to recent advances in asteroseismology. Thanks to the unprecedented data quality obtained by space missions, particularly CoRoT and Kepler, invaluable information is extracted from the high-precision stellar oscillation frequencies, which provide very strong constraints on possible stellar models for a given set of classical observations. In this work, we have characterized two relatively faint stars, KIC 10920273 and KIC 11395018, using oscillation data from Kepler photometry and atmospheric constraints from ground-based spectroscopy. Both stars have very similar atmospheric properties; however, using the individual frequencies extracted from the Kepler data, we have determined quite distinct global properties, with increased precision compared to that of earlier results. We found that both stars have left the main sequence and characterized them as follows: KIC 10920273 is a one-solar-mass star (M = 1.00 ± 0.04 M☉), but much older than our Sun (t = 7.12 ± 0.47 Gyr), while KIC 11395018 is significantly more massive than the Sun (M = 1.27 ± 0.04 M☉) with an age close to that of the Sun (t = 4.57 ± 0.23 Gyr). We confirm that the high lithium abundance reported for these stars should not be considered to represent young ages, as we precisely determined them to be evolved subgiants. We discuss the use of surface lithium abundance, rotation, and activity relations as potential age diagnostics.
Cosmological axino problem

We revisit the cosmology of the supersymmetric QCD axion, highlighting the existence of a serious cosmological axino problem that is fully analogous to the gravitino problem of overclosure via thermal production. A general analysis implies that the QCD axino has a mass greater than or equal to that of the gravitino in the absence of unnatural fine-tuning or sequestering. As a consequence, bounds from thermal gravitino and QCD axino production are complementary in parameter space, and together provide a quite stringent limit on the reheating temperature after inflation given by T_R < 10^3 - 10^6 GeV for an axion decay constant of f_a = 10^9 - 10^12 GeV. Motivated by this result, we explore the cosmology of gravitino LSP and axino NLSP at low T_R and present three realistic scenarios for dark matter.
Liquid and Ice Cloud Microphysics in the CSU General Circulation Model. Part II: Impact on Cloudiness, the Earth's Radiation Budget, and the General Circulation of the Atmosphere

Abstract A prognostic equation for the mass of condensate associated with large-scale cloudiness introduces a direct coupling between the atmospheric moisture budget and the radiation budget through interactive cloud amounts and cloud optical properties. We have compared the cloudiness, the top-of-the-atmosphere and surface radiation budgets, the radiative forcing of clouds, and the atmospheric general circulation simulated with the Colorado State University general circulation model with and without such a prognostic cloud parameterization. In the EAULIQ run, the radiative effects of cloud water, cloud ice, and snow are considered; those of rain are omitted. The cloud optical depth and cloud infrared emissivity depend on the cloud water, cloud ice, and snow paths predicted by a bulk cloud microphysics parameterization. In the CONTROL run, a conventional large-scale condensation scheme is used. Cloud optical properties depend on the mean cloud temperatures. Results are presented in terms of January and Ju.
Effects of In-Store Decorative Elements on Children Shopping Behaviour

Children play a significant role in determining the family's shopping expenses, which is as important as an adult's. However, the research found that having a child companion can reduce positive shopping values due to the child's behaviour. The focus of this research is to understand the effects of in-store decorative elements on children aged between three to seven years of shopping experience. The qualitative methodology using ethnography studies is employed to identify key factors affecting children's emotional and behavioural responses. It also discusses research insight that could help to improve business strategy for children customers.

Double charmonium production in exclusive bottomonia decays

This paper is devoted to the leading twist exclusive bottomonia decays with double charmonium in the final state. Using models of the twist-2 charmonia distribution amplitudes the widths of these decays are calculated within light cone formalism. In addition, the processes under consideration are studied within nonrelativistic QCD. In our analysis we have found that the production of some of the $P$-wave charmonia mesons with $L_z \neq 0$ is allowed already at the leading twist approximation. This means that the selection rules which predict the suppression of such decays are violated. The mechanism which lies behind this violation is discussed.

The National Amil Zakat Agency (BAZNAS) is the official and only body established by the government which has the task and function of collecting and distributing zakat, infaq and alms (ZIS) at the national level. Human resources are one of the important factors for BAZNAS in carrying out its operational activities. This study aims to examine the effect of work environment, locus of control and motivation on employee performance. This type of research is quantitative research. The sampling technique used in this study is the saturated sampling technique, which is a sampling technique in which all members of the population are used as samples. In this study, researchers used a sample of 32 employees of BAZNAS, South Sumatra Province. The data analysis technique used is multiple regression analysis with the help of SPSS software. The results showed that the work environment had a positive and significant effect on employee performance, locus of control had a positive and significant effect on employee performance and motivation had a positive and significant effect on employee performance.Simultaneously the work environment, locus of control and motivation affect employee performance by 88.7%, while the remaining 11.3% is influenced by other variables that have not been studied or are not included in the regression in this study.
