People are becoming used to fake world and vocal communication as technology advances. There are a few ways to communicate with people online in this modern invention. A large number of individuals often choose and use the simplest form of reporting, namely email. The era of encrypted email allows users to communicate with other people by posting signals and also facilitates cross-border corporate communication. Some individuals are unable to take advantages of this technology due to their ignorant or lack the necessary visible screen ability. Therefore, a Speech completely messaging device is suggested using Py but instead Ai to save time for externally examined people. Its device gives those who have been evaluated on the outside some power of contact and considerably increases their sense of stability as objectivity. With the use of that invention, blind persons will indeed be able to send out emails just like other regular citizens. Voice-based messaging systems use cutting-edge technology to ensure their legitimacy to people who have been vetted on the outside.

Nickel and cobalt layered double hydroxide (NiCo-LDH) is one of promising active materials of battery supercapacitor hybrids (BSH) as the clean renewable energy. Designing composites and doping heteroatoms are widely applied to solve poor conductivity, serious agglomeration, and structural defects of NiCo-LDH. In this work, manganese cobalt LDH (MnCo-LDH) is firstly incorporated in sulfur-doped NiCo-LDH (S-NiCo-LDH) on Ni foam (NF) via the hydrothermal process as a binder-free electrode of BSH. Favorable morphology with nanowires covered on the vertical grown nanosheet array is successfully designed for MnCo-LDH/S-NiCo-LDH with the large specific surface area and the well-established pore structure. The specific capacitances (CF) of 681.4, 953.9 and 1581.3 F/g are respectively achieved for the NiCo-LDH, S-NiCo-LDH, MnCo-LDH/S-NiCo-LDH electrodes at the current density of 1 A/g. The larger CF value of MnCo-LDH/S-NiCo-LDH is due to larger conductivity and effective charge transfer paths. A BSH assembled using MnCo-LDH/S-NiCo-LDH/NF and graphene/NF electrodes shows a wide potential window of 1.6 V, a large maximum energy density of 46.6 Wh/kg at 0.8 kW/kg, and an excellent cyclic stability with the CF retention of 81% and the Coulombic efficiency higher than 87% after 10,000 times charge/discharge process at the current density of 7 A/g. © 2022

This article explores the value of science fiction narratives in games for citizen science. Focusing on the protein-folding game Foldit, it describes the process of modifying and redesigning the game to feature a framing narrative and other alterations to the main tutorial campaign. The campaign narrative, Foldit: First Contact, situates the practices of citizen science in an expanded context of meanings and ethical implications, promoting critical self-reflection on the relations of science and civic values. A study of player responses to Foldit: First Contact suggests the significance of science fiction and critical game design for attuning citizen scientists to the collective responsibilities of experimentation and innovation, drawing attention to the intersecting social, technical, and environmental domains in which gamers may contribute to scientific research.

Let Γ be a finite graph and let A(Γ) be the corresponding right-angled Artin group. We characterize the Hamiltonicity of Γ via the structure of the cohomology algebra of A(Γ). In doing so, we define and develop a new canonical graph associated to a matrix, which as a consequence provides a novel perspective on the matrix determinant. Copyright © 2021, The Authors.

With an intention to improve performance characteristics of the savonius hydrokinetic turbine several modifications were made on the geometrical parameters of the savonius turbine. Though modifications were done on geometrical parameters of savonius turbine but the power coefficient of the savonius turbine didn’t increase compared to the horizontal axis turbines. Augmentation devices are the best alternative to increase the power coefficient of savonius hydrokinetic turbine. Augmentation devices are very effective compared to the other design parameters of savonius hydrokinetic turbine. In this paper, various augmentation devices were used to increase the power coefficient of the modified fixed flip type savonius hydrokinetic turbine. The augmentation devices are used in the present work are, flat deflector, inclined deflector, convergent guide box, convergent–divergent guide box, and Nozzle. The power coefficient was improved with the use of augmentation devices whereas it was very less without augmentation devices. Two deflector with an angle inclination of 45° and 15° has shown maximum power coefficient of 0.54. Modified four bladed fixed flip savonius hydrokinetic turbine without augmentation arrangement shown the, maximum power coefficient of 0.173.

Probabilistic Genotype-Phenotype Maps Reveal Mutational Robustness of RNA Folding, Spin Glasses, and Quantum Circuits

Recent studies of genotype-phenotype (GP) maps have reported universally enhanced phenotypic robustness to genotype mutations, a feature essential to evolution. Virtually all of these studies make a simplifying assumption that each genotype—represented as a sequence—maps deterministically to a single phenotype, such as a discrete structure. Here, we introduce probabilistic genotype-phenotype (PrGP) maps, where each genotype maps to a vector of phenotype probabilities, as a more realistic and universal language for investigating robustness in a variety of physical, biological, and computational systems. We study three model systems to show that PrGP maps offer a generalized framework which can handle uncertainty emerging from various physical sources: (1) thermal fluctuation in RNA folding, (2) external field disorder in spin glass ground state finding, and (3) superposition and entanglement in quantum circuits, which are realized experimentally on IBM quantum computers. In all three cases, we observe a novel biphasic robustness scaling which is enhanced relative to random expectation for more frequent phenotypes and approaches random expectation for less frequent phenotypes. We derive an analytical theory for the behavior of PrGP robustness, and we demonstrate that the theory is highly predictive of empirical robustness. © 2023, CC BY.

Finite element modeling of the seepage flow of water under concrete dams with sheet piles

AIP Conference Proceedings 2024年第1期3034卷

作者： Raed Abokwiek Rami H. Hawileh Jamal A. Abdalla Graduate student Material Science and Engineering PhD Program American University of Sharjah P.O.Box 26666 Sharjah United Arab Emirates Professor Department of Civil Engineering American University of Sharjah P.O.Box 26666 Sharjah United Arab Emirates

A finite element model (FEM) is developed to analyze the problem of seepage flow of water under concrete dams with sheet piles. The model was developed using the finite element software ANSYS, based on equivalent thermal analysis and correlation with seepage performance. The issue of water seepage under concrete dams is addressed mathematically. In this study, the effects of several parameters on porous soil seepage velocity distribution are studied. Sheet pile parameters were varied in depth, location and number of sheet piles. The sheet pile with variables of 0, 1, 2, and 3 pieces, location of 0, 0.5, and 1 of dam width, and the depth of the sheet piles varying as 2 and 4 m, respectively. The developed FE models were verified by a previous study and used for further parametric studies. It was concluded that increased sheet pile depth reduces the seepage flow. In addition, the location of the sheet pile is an important factor in seepage velocity, as it might increase the flow away from dam toe in a similar fashion to dam depth effects. Moreover, increasing the number of sheet piles further reduces the seepage velocity in comparison to usage of a single sheet pile. The sheet pile configuration and parameters are integrated with each other and each factor influence the others, resulting in various seepage flow patterns. This study demonstrates that FE modeling can effectively predict seepage flow under concrete dams with sheet piles.

In 2017 summer, we observed a widespread bottom hypoxic zone at the lower estuary of the Pearl River estuary (PRE). We observed i) bacterial and AOA biomass accumulation, ii) oxygen consumption rates (respiration and nitrification) in the hypoxic zone. The potential microbial interaction of both oxygen-consuming microbes in the hypoxia remained unclear. To investigate the potential microbial interaction between AOA and heterotrophic bacteria in the hypoxic zone, we used bacterial and AOA communities (inferred from 16S rRNA gene and amoA gene, respectively) and multi-comparisons between the co-occurrence networks retrieved from DNA and RNA levels to reflect the pattern. We observed a highly diverse and active bacterial community in the hypoxia zone. The network topology revealed that Gammaproteobacteria, Bacteroidetes (Flavobacteriales), Alphaproteobacteria (Rhodobacterales and Rhodospirillales), Marinimicrobia, Cyanobacteria (Synechococcales), and AOA sublineages were module hubs and connectors, indicating that they were the keystone taxa of the microbial communities. The hub-subnetwork further showed robust co-occurrence between Gammaproteobacteria, Bacteroidetes (Flavobacteriales), Alphaproteobacteria (Rhodobacterales and Rhodospirillales), Marinimicrobia with AOA sublineages, and Nitrospinae (presumably NOB)) reflecting the formation of Degradation-Nitrification microbial assemblage in the hypoxia zone. The subnetworks revealed AOA ecotype-specific modularization and niche partitioning of different AOA sublineages. Interestingly, the recurring co-occurrence of SCM1-like II sublineages with Nitrospinae OTUs formed nitrifiers assemblage in the RNA subnetworks suggested an interaction via nitrite exchange. The Degradation-Nitrification microbial assemblage may contribute substantially to the oxygen consumption in the hypoxia formation in PRE. Our results provide new insight into the nitrifier-associated microbial assemblage that should be further explored in the mar

Autism is a heterogeneous neurodevelopmental condition, and functional magnetic resonance imaging-based studies have helped advance our understanding of its effects on brain network activity. We review how predictive modeling, using measures of functional connectivity and symptoms, has helped reveal key insights into this condition. We discuss how different prediction frameworks can further our understanding of the brain-based features that underlie complex autism symptomatology and consider how predictive models may be used in clinical settings. Throughout, we highlight aspects of study interpretation, such as data decay and sampling biases, that require consideration within the context of this condition. We close by suggesting exciting future directions for predictive modeling in autism.
