The complex physics of dusty star-forming galaxies at high redshifts as revealed by Herschel and Spitzer
(IOP Publishing, 2013)We combine far-infrared photometry from Herschel (PEP/HerMES) with deep mid-infrared spectroscopy from Spitzer to investigate the nature and the mass assembly history of a sample of 31 luminous and ultraluminous infrared ... -
Complex sequential data analysis: A systematic literature review of existing algorithms
(SAICSIT, 2020)This paper provides a review of past approaches to the use of deep-learning frameworks for the analysis of discrete irregularpatterned complex sequential datasets. A typical example of such a dataset is financial data ... -
Complexation-based detection of nickel(ii) at a graphene-chelate probe in the presence of cobalt and zinc by adsorptive stripping voltammetry
(MDPI, 2017)The adsorptive stripping voltammetric detection of nickel and cobalt in water samples at metal film electrodes has been extensively studied. In this work, a novel, environmentally friendly, metal-free electrochemical ... -
Compliance with research ethics in epidemiological studies targeted to conflict-affected areas in Western Ethiopia: validity of informed consent (VIC) by information comprehension and voluntariness (ICV)
(BioMed Central Ltd, 2024)Background: The conduct of research is critical to advancing human health. However, there are issues of ethical concern specific to the design and conduct of research in conflict settings. Conflict-affected countries often ... -
Components for PEM fuel cells: An overview
(Trans Tech Publications, 2010)Fuel cells, as devices for direct conversion of the chemical energy of a fuel into electricity by electrochemical reactions, are among the key enabling technologies for the transition to a hydrogen-based economy. Among ... -
A comprehensive data-driven odyssey to explore the equation of state of dark energy
(Springer Nature, 2024)For the first time, we reconstruct the dark energy equation of the state parameter w from the combination of background and perturbation observations, specifically combining the Hubble parameter data from cosmic chronometer ... -
A comprehensive review on hydrogen absorption behaviour of metal alloys prepared through mechanical alloying
(MDPI, 2020)Hydride-forming alloys are currently considered reliable and suitable hydrogen storage materials because of their relatively high volumetric densities, and reversible H2 absorption/desorption kinetics, with high storage ... -
A comprehensive study of modulation effects on CMB polarization
(Springer, 2022)The Cosmic Microwave Background is characterized by temperature and linear polar ization fields. Dipole modulation in the temperature field has been extensively studied in the context of hemispherical power asymmetry. In ... -
A comprehensive survey on Fog Computing: State-of-the-art and research challenges
(IEEE, 2018)Cloud computing with its three key facets (i.e., Infrastructure-as-a-Service, Platform-as-a-Service, and Softwareas- a-Service) and its inherent advantages (e.g., elasticity and scalability) still faces several challenges. ... -
Computational and preclinical prediction of the antimicrobial properties of an agent isolated from monodora myristica: A novel dna gyrase inhibitor
(MDPI, 2023)The African nutmeg (Monodora myristica) is a medically useful plant. We, herein, aimed to critically examine whether bioactive compounds identified in the extracted oil of Monodora myristica could act as antimicrobial ... -
Computational approaches for the design of novel anticancer compounds based on pyrazolo[3,4-d]pyrimidine derivatives as trap1 inhibitor
(Switzerland: MDPI AG, 2021)In the present in-silico study, various computational techniques were applied to determine potent compounds against TRAP1 kinase. The pharmacophore hypothesis DHHRR_1 consists of important features required for activity. ... -
