In this paper, we derive some subordination and superordination results for the generalized "Srivastava-Attiya" fractional integral operator. Some interesting corollaries for this operator is also obtained.

The use of HLA-identical hematopoietic stem cell transplantation (HSCT) demonstrates overall survival rates greater than 75 % for T-B-NK+ severe combined immunodeficiency secondary to pathogenic mutation of recombinase activating genes 1 and 2 (RAG1/2). Limited data exist regarding the use of HSCT in patients with hypomorphic RAG variants marked by greater preservation of RAG activity and associated phenotypes such as granulomatous disease in combination with autoimmunity. We describe a 17-year-old with combined immunodeficiency and immune dysregulation characterized by granulomatous lung disease and autoimmunity secondary to compound heterozygous RAG mutations. A myeloablative reduced toxicity HSCT was completed using an unrelated bone marrow donor. With the increasing cases of immune dysregulation being discovered with hypomorphic RAG variants, the use of HSCT may advance to the forefront of treatment. This case serves to discuss indications of HSCT, approaches to preparative therapy, and the potential complications in this growing cohort of patients with immune dysregulation and RAG deficiency.

Summary: In this paper, we present the first principle investigations for structural and optoelectronic properties of pure, n‐type, p‐type, and co‐doped MgSiP2 chalcopyrite compounds. To examine the structural and optoelectronic response, density functional theory (DFT) as embodied in Wien2k method is utilized. Within DFT, we have considered the exchange correlation functional prescribed by Perdew‐Burke‐Ernerhof generalized gradient approximation and Tran‐Blaha modified Becke Johnson for all computation presented in this paper. The results obtained from present calculations are in well reconciliation with previously reported experimental and theoretical data for pure compound, which affirms the accuracy of present computations. The electronic responses of all compounds are investigated through the crystal structure, energy band structure, and density of states. Optical responses of studied compounds are explained in terms of dielectric tensor, absorption, reflectivity, and refractivity spectra. Drastic change in energy band gap from pure (2.04 eV) to co‐doped compound (0.30 eV) is observed. The obtained band gaps and absorption range confirm the utility of these compounds in photovoltaic application. [ABSTRACT FROM AUTHOR]

In the present investigation we introduce two new subclasses M S ∗ q (p, b; c) and M K q(p, b; c) of meromorphic multivalent functions by using q-derivative operator defined in the punctured unit disc. We use the Cassinian Oval √ 1 + cz with c ∈ (0, 1] as a subordinant function in this treatise. Also we derive several properties including convolution properties, the necessary and sufficient condition and coefficient estimates for these subclasses. [ABSTRACT FROM AUTHOR]

This article is an attempt to investigate the impact of mergers and acquisitions (M&As) on corporate performance of Indian IT sector for the period 2007–2015. The focus of this article is on Indian IT sector as it has been the growth engine of the economy and emerging as its most internationalised sector. This article has engaged, fixed and random effect panel data models to measure the impact of M&As on various financial variables with comparative analysis of domestic and cross border deals. The findings reveal that the M&As have significant positive impact on Return on Net worth and Revenue of IT companies in India when both domestic and cross-border regions were considered together. Whereas, Earnings Before Interest, Taxes, Depreciation and Amortisation experienced significant decline. Return on Capital Employed did not experience any significant impact due to M&As. When the impact of M&As was analysed separately for domestic and cross-border deals, it was obtained that the impacts are in different directions for domestic and cross-border deals in two out of four variables. The significant inference is that domestic deals per se are much better than the cross border deals. [ABSTRACT FROM AUTHOR]

We report systematic investigations of opto-electronic behavior of promising semiconducting chalcopyrite compounds Cu2In(Al,Ga)Se4 within the framework of density functional theory. In view to explore their possible utilization in opto-electronic devices, we have firstly performed calculations using one of the most accurate prescriptions, namely full-potential linearized augmented plane wave method. For a better accuracy, computations have been carried out using different exchange–correlation potentials including the most accurate modified Becke–Johnson potential with hybrid functional features. Computations have been performed for various electronic and optical properties such as energy bands, total and partial density of states, real and imaginary parts of dielectric tensors, absorption spectra, reflection, refraction and energy loss spectra for both chalcopyrite compounds. We have compared our data with the existing experimental and theoretical calculations for both compounds, which validates the accuracy of present computations. Both chalcopyrites are observed to have a direct band gap nature (Cu2InAlSe4: 1.14 eV and Cu2InGaSe4: 0.96 eV). Energy peaks recorded in the imaginary part of dielectric tensors are well interpreted by means of inter-band transitions. Significant intensities observed in absorption spectra within the energy range of solar spectra unambiguously depict feasibility of these compounds in optoelectronic devices. [ABSTRACT FROM AUTHOR]
