THE NEXT GENERATION VIRGO CLUSTER SURVEY. XV. THE PHOTOMETRIC REDSHIFT ESTIMATION FOR BACKGROUND SOURCES

The Next Generation Virgo Cluster Survey (NGVS) is an optical imaging survey covering 104 deg2 centered on the Virgo cluster. Currently, the complete survey area has been observed in the u*giz bands and one third in the r band. We present the photometric redshift estimation for the NGVS background sources. After a dedicated data reduction, we perform accurate photometry, with special attention to precise color measurements through point-spread function homogenization. We then estimate the photometric redshifts with the Le Phare and BPZ codes. We add a new prior that extends to iAB = 12.5 mag. When using the u* griz bands, our photometric redshifts for 15.5 mag ⩽ i ≲ 23 mag or zphot ≲ 1 galaxies have a bias |Δz| < 0.02, less than 5% outliers, a scatter σoutl. rej. , and an individual error on zphot that increases with magnitude (from 0.02 to 0.05 and from 0.03 to 0.10, respectively). When using the u*giz bands over the same magnitude and redshift range, the lack of the r band increases the uncertainties in the 0.3 ≲ zphot ≲ 0.8 range (−0.05 < Δz < −0.02, σoutl.rej ∼ 0.06, 10%–15% outliers, and zphot.err. ∼ 0.15). We also present a joint analysis of the photometric redshift accuracy as a function of redshift and magnitude. We assess the quality of our photometric redshifts by comparison to spectroscopic samples and by verifying that the angular auto- and cross-correlation function w(θ) of the entire NGVS photometric redshift sample across redshift bins is in agreement with the expectations.
COSMOLOGICAL CONSTRAINTS FROM SUNYAEV–ZELDOVICH CLUSTER COUNTS: AN APPROACH TO ACCOUNT FOR MISSING REDSHIFTS

The accumulation of redshifts provides a significant observational bottleneck when using galaxy cluster surveys to constrain cosmological parameters. We propose a simple method to allow the use of samples where there is a fraction of the redshifts that are not known. The simplest assumption is that the missing redshifts are randomly extracted from the catalog, but the method also allows one to take into account known selection effects in the accumulation of redshifts. We quantify the reduction in statistical precision of cosmological parameter constraints as a function of the fraction of missing redshifts for simulated surveys, and also investigate the impact of making an incorrect assumption for the distribution of missing redshifts.
An extension of Mercer theorem to vector-valued measurable kernels

We extend the classical Mercer theorem to reproducing kernel Hilbert spaces whose elements are functions from a measurable space $X$into $\mathbb C^n$. Given a finite measure $\mu$ on $X$, we represent the reproducing kernel $K$ as convergent series in terms of the eigenfunctions of a suitable compact operator depending on $K$ and $\mu$. Our result holds under the mild assumption that $K$ is measurable and the associated Hilbert space is separable. Furthermore, we show that $X$ has a natural second countable topology with respect to which the eigenfunctions are continuous and the series representing $K$ uniformly converges to $K$ on any compact subsets of $X\times X$, provided that the support of $\mu$ is $X$.
Quantization of Emergent Gravity

Emergent gravity is based on a novel form of the equivalence principle known as the Darboux theorem or the Moser lemma in symplectic geometry stating that the electromagnetic force can always be eliminated by a local coordinate transformation as far as space–time admits a symplectic structure, in other words, a microscopic space–time becomes noncommutative (NC). If gravity emerges from U(1) gauge theory on NC space–time, this picture of emergent gravity suggests a completely new quantization scheme where quantum gravity is defined by quantizing space–time itself, leading to a dynamical NC space–time. Therefore the quantization of emergent gravity is radically different from the conventional approach trying to quantize a phase space of metric fields. This approach for quantum gravity allows a background-independent formulation where space–time and matter fields are equally emergent from a universal vacuum of quantum gravity.
Techno‐economic studies on the variable compression ratio dual fuel diesel‐producer gas CI engine utilizing different biomass feedstocks

In this study, a techno‐economic analysis for a 3.75 kW biomass gasification power generation system (BMPGS) was conducted by exploiting available biomass resources such as rice husk, coconut shell, and rubber shell as feedstock. Payback time (PBT), net present value (NPV), and life cycle cost are the economic criteria that are delivered by an economic model for a BMPGS. Experimental results obtained on the technical parameters of a BMPGS, show that the rubber shell operated BMPGS has the highest overall efficiency (15.5%), maximum diesel savings (48%), and least biomass consumption (3.3 kg/h). Even though the capital cost of the producer gas driven dual fuel CI engine is higher than the standalone diesel genset power production system, it has the lowest running cost and cost savings per year, making it an excellent choice for power generation in remote locations. The rubber shell operated BMPGS system show a minimum PBT of 2.9 years which is desirable as the cost for installation of the proposed system can be regained within a short period of time. A positive NPV of Rs. 3,90,000 is attained for rubber shell, which clearly indicates in acceptance of rubber shell as biomass feedstock for BMPGS. The sensitivity analysis proves that the uncertainty in input parameters such as the cost of a biomass gasifier, dual fuel VCR engine, labor cost, and the cost of biomass feedstock influence the output parameters of the capital cost, operating cost, and PBT.
Investigation of beta beta decay in (150)Nd and (148) Nd to the excited states of daughter nuclei

Double beta decay of 150 Nd and 148 Nd to the excited states of daughter nuclei have been studied using a 400 cm 3 low-background HPGe detector and an external source consisting of 3046 g of natural Nd 2 O 3 powder. The half-life for the two-neutrino double beta decay of 150 Nd to the excited 0 + 1 state in 150 Sm is measured to be T 1/2 = [1.33 +0.36 ―0.23 (stat) +0.27 ―0.13 (syst)] × 10 20 yr. For other (0v + 2v) transitions to the 2 + 1 , 2 + 2 , 2 + 3 , and 0 + 2 levels in 150 Sm, limits are obtained at the level of ∼(2―8) x 10 20 yr. In the case of 148 Nd only limits for the (0v + 2v) transitions to the 2 + 1 , 0 + 1 , and 2 + 2 excited states in 148 Sm were obtained and are at the level of ∼(4―8) × 10 20 yr.
Bicategories and Weakly Globular Double Categories

This paper introduces the notion of weakly globular double categories, a particular class of strict double categories, as a way to model weak 2-categories; it explores its use in defining a double category of fractions, and shows that the sub-2-category of groupoidal weakly globular double categories forms an algebraic model of homotopy 2-types.
Race, citizenship, and belonging in the pursuit of water and climate justice in California

Systemic inequalities, which affect how water is distributed and used, underlie water insecurities in higher-income (global North) countries. We explore the interlinkages between municipal decision-making and infrastructure to understand how urban climate justice can be advanced through engaging with state-like forms of governance. Drawing on archival information, spatial analysis, participant observation, and semi-structured interviews in the underbounded Latinx community of East Porterville, California, we analyze how local actors actively work against municipal-scale processes of infrastructure exclusion and production, within and beyond the state, to facilitate water access and particular notions of citizenship. We argue urban climate justice demands both an understanding of infrastructural marginalization, and attention to the diversity of perspectives, approaches, and solutions preferred by communities.

Effect of Computerized Accounting System on Organisational Performance of Oil and Gas Firms in Port Harcourt, Nigeria

The study examined the effect of a computerized accounting system (CAS) on the organisational performance of oil and gas firms in Port-Harcourt, Nigeria. The study adopts the survey research design. The survey enabled the researcher to obtain information from respondents about practices, situations or views via questionnaires. The population comprised of hundred staff of five randomly selected Oil and Gas firms in Port Harcourt, Rivers State with a capital base of above 500 million. The unit of focus was personnel in the Accounting/Finance and the IT/ICT Department of the respective companies. The study is based on primary data obtained from a structured questionnaire administered to respondents. The reliability of the instrument was measured using Cronbach’s alpha. The data were analysed using descriptive and inferential statistics. The hypotheses were tested using simple linear regression. The results showed a positive significant effect of accounting software usage on accountability, productivity, and cost control in oil and gas firms. Based on this the study recommends the use of electronic mediums and other alternative channels (such as cloud computing frameworks) for storing financial information to ensure the safeguarding of such information and prevent data loss. The deployment of CAS in functional departments to boost the efficiency of service delivery in addition to linkage to the overall organisational ICT framework can enable the speedy generation of internal and external financial reports.
Orientation Prediction for VR and AR Devices Using Inertial Sensors Based on Kalman-Like Error Compensation

We propose an orientation prediction algorithm based on Kalman-like error compensation for virtual reality (VR) and augmented reality (AR) devices using measurements of an inertial measurement unit (IMU), which includes a tri-axial gyroscope and a tri-axial accelerometer. First, the initial prediction of the orientation is estimated by assuming linear movement. Then, to improve the prediction accuracy, the accuracies of previous predictions are taken into account by computing the orientation difference between the current orientation and previous prediction. Finally, we define a weight matrix to determine the optimal adjustments for predictions corresponding to a given orientation, which is obtained by minimizing the estimation errors based on the minimum mean square error (MMSE) criterion using Kalman-like error compensation. Experimental results demonstrate that the proposed algorithm exhibits higher orientation prediction accuracy compared with conventional algorithms on several open datasets.
Tuberculosis Epididymo-Orchitis Mimicking Malignancy Resulting from Intravesical Bacillus Calmette–Guérin Immunotherapy for Bladder Cancer: A Case Report of a Rare Complication

Tuberculous epididymo-orchitis is a rare complication of intravesical bacillus Calmette–Guérin (BCG) immunotherapy for bladder cancer. We report a patient with bladder cancer and a history of intravesical BCG immunotherapy who presented with right scrotal pain for 1 week. A heterogeneous, hypoechoic, and solid mass surrounded by increased blood flow in the right testis was seen on scrotal echogram. Urine ordinary and tuberculosis culture yielded negative results. After failure of antibiotic treatment and the inability to rule out tumor, the diagnosis was confirmed by radical orchiectomy. Acid-fast staining of pus in the tumor and tumor tissue was positive, and a pus culture was positive for Mycobacteria tuberculosis complex. Right radical orchiectomy was performed, and anti-tuberculosis treatment with rifampicin, isoniazid, ethambutol, and pyrazinamide was given. The patient is still currently under anti-tuberculosis treatment, and no significant adverse effects have been noted. BCG-related epididymo-orchitis should be suspected in patients with a history of intravesical BCG immunotherapy if the empiric antibiotic treatment typically used to treat common epididymo-orchitis fails.
Nature of the Unidentified TeV Source HESS J1614-518, Revealed by Suzaku and XMM-Newton Observations

We report on new Suzaku and XMM-Newton results concerning HESS J1614-518, which is one of the brightest extended TeV gamma-ray sources and has two regions with intense gamma-ray emission. We newly observed the south and center regions of HESS J1614-518 with Suzaku, since the north region, including the position of the 1st brightest peak of the TeV gamma-ray emission, has already been observed. No X-ray counterpart was found at the position of the 2nd brightest peak of the TeV gamma-ray emission; we estimated the upper limit of the X-ray flux to be 1.6 \times 10^{-13} erg cm^{-2} s^{-1} in the 2-10 keV band. The soft X-ray source Suzaku J1614-5152, which was found at the edge of the field of view in a previous observation, was also detected at the middle of HESS J1614-518. Analyzing the XMM-Newton archival data, we revealed that Suzaku J1614-5152 consists of multiple point sources. The X-ray spectrum of the brightest point source, XMMU J161406.0-515225, can be described by a power-law model with a photon index of Gamma = 5.2^{+0.6}_{-0.5}, or a blackbody model with temperature kT = 0.38^{+0.04}_{-0.04} keV. In the blackbody model, the hydrogen-equivalent column density is almost the same as that of the hard extended X-ray emission, Suzaku J1614-5141, which was found at the 1st peak position. If true, XMMU J161406.0-515225 may be physically related to Suzaku J1614-5141 and HESS J1614-518.
What can COVID‐19 pandemic reveal about public purpose of a University? A case study

Abstract This case study examines institutional communication of purpose to stakeholders through Facebook during the COVID‐19 pandemic. The findings show that the institution attempted to reduce the negative impacts of the pandemic on campus life and student experiences while using the pandemic as an opportunity to re‐iterate the importance of its scientific knowledge production, training of professionals, and service to communities. In doing so, it established relationships with multiple publics at a time of crisis, but has run the risk of further losing public trust in science and university as the COVID‐19 pandemic has persisted.
Lower bounds on the Calabi functional

The main result of this paper shows that "test configurations" give new lower bounds on the $L^{2}$ norm of the scalar curvature on a Kahler manifold. This is closely analogous to the analysis of the Yang-Mills functional over Riemann surfaces by Atiyah and Bott. The proof uses asymptotic approximation by finite-dimensional problems: the essential ingredient being the Tian-Zelditch-Lu expansion of the "density of states" function.
ORIENTATION EFFECTS ON THE INNER REGION OF DUSTY TORUS OF ACTIVE GALACTIC NUCLEI

A sublimation process governs the innermost region of the dusty torus of active galactic nuclei. However, the observed inner radius of the torus is systematically smaller than the expected radius by a factor of ∼1/3. We show that the anisotropy of the emission from accretion disks resolves this conflict naturally and quantitatively. An accretion disk emits lesser radiation in the direction closer to its equatorial plane (i.e., to the torus). We find that the anisotropy makes the torus inner region closer to the central black hole and concave. Moreover, the innermost edge of the torus may connect with the outermost edge of the disk continuously. Considering the anisotropic emission of each clump in the torus, we calculate the near-infrared flux variation in response to a UV flash. For an observer at the polar angle θobs = 25°, the centroid of the time delay is found to be 37% of the delay expected in the case of isotropic illumination, which explains the observed systematic deviation.
Minimal Spanning Trees on Infinite Sets

Minimal spanning trees on infinite vertex sets are investigated. A criterion for minimality of a spanning tree having a finite length is obtained, which generalizes the corresponding classical result for finite sets. It is given an analytic description of the set of all infinite metric spaces which a minimal spanning tree exists for. A sufficient condition for a minimal spanning tree existence is obtained in terms of distances achievability between partitions elements of the metric space under consideration. Besides, a concept of locally minimal spanning tree is introduced, several properties of such trees are described, and relations of those trees with (globally) minimal spanning trees are investigated.
Decentralised approach of wastewater treatment and impact assessment of treated and untreated wastewater irrigation on agriculture land and its produce

A field experiment was conducted from October, 2015 – March, 2017 to investigate the effects of drip irrigation with wastewater, and treated wastewater on crop quality at the 12-C Research farm of Indian Agriculture Research Institute, New Delhi. A bioreactor was installed at 12-C field for the purpose of cleaning the wastewater for the irrigation. After wastewater irrigation, the level of metals in the wastewater irrigated field got increased with time in the soil. While in treated water irrigated soil, concentration of metals was very less. In case of crops, the level of heavy metals was found more in wastewater irrigated crops than the treated water irrigated crops. From the study, it can be concluded that unlike treated wastewater, untreated wastewater cannot be used in agricultural land for a long time. Further, use of treated wastewater for irrigation does not have a negative impact on the consumers’ health as well.
Drinfeld center of planar algebra

We introduce fusion, contragradient and braiding of Hilbert affine representations of a subfactor planar algebra $P$ (not necessarily having finite depth). We prove that if $N \subset M$ is a subfactor realization of $P$, then the Drinfeld center of the $N$-$N$-bimodule category generated by $_N L^2 (M)_M$, is equivalent to the category of Hilbert affine representations of $P$ satisfying certain finiteness criterion. As a consequence, we prove Kevin Walker's conjecture for planar algebras.
Cluster algebras and semi‐invariant rings I. Triple flags

We prove that each semi‐invariant ring of the complete triple flag of length n is an upper cluster algebra associated to an ice hive quiver. We find a rational polyhedral cone Gn such that the generic cluster character maps its lattice points onto a basis of the upper cluster algebra. As an application, we use the cluster algebra structure to find a special minimal set of generators for these semi‐invariant rings when n is small.
Operators of Harmonic Analysis in Variable Exponent Lebesgue Spaces. Two-Weight Estimates

In the paper two-weighted norm estimates with general weights for Hardy-type transforms, maximal functions, potentials and Calder\'on-Zygmund singular integrals in variable exponent Lebesgue spaces defined on quasimetric measure spaces $(X, d, \mu)$ are established. In particular, we derive integral-type easily verifiable sufficient conditions governing two-weight inequalities for these operators. If exponents of Lebesgue spaces are constants, then most of the derived conditions are simultaneously necessary and sufficient for appropriate inequalities. Examples of weights governing the boundedness of maximal, potential and singular operators in weighted variable exponent Lebesgue spaces are given.
Pengaruh Financial Literacy, Herding Behavior dan Overconfidence terhadap Investment Decision

Indonesia mengalami lonjakan investor pada tahun 2021 sebanyak hampir dua kali dari jumlah investor sebelumnya. Meski investasi mulai digemari oleh masyarakat namun tidak semua investor mampu mengambil keputusan yang tepat dalam berinvestasi.

The sample was obtained through a purposive sampling technique, where respondents had to meet pre-set criteria. The criteria in this study are that the investor must be female, domiciled in Jakarta, have invested in the capital market for at least 1 year and have made a minimum of 2 transactions. The results obtained in this study are financial literacy has a positive effect on investment decisions, herding behavior has a positive effect on investment decisions and overconfidence has a positive effect on investment decisions.
On vertex-uniprimitive non-Cayley graphs of order pq

Let $p$ and $q$ be distinct odd primes. Let $\Gamma=(V(\Gamma), E(\Gamma))$ be a non-Cayley vertex-transitive graph of order $pq. $ Let $G\leq \Aut(\Gamma)$ acts primitively on the vertex set $V(\Gamma)$. In this paper, we show that $G$ is uniprimitive which is primitive but not 2-transitive and we obtain some information about $p, q$ and the minimality of the Socle $T=\soc(G). $
