On Chebyshev and Riemann-Liouville Fractional Inequalities in q-Calculus
Authors: Ajega-Akem Stephen. N. , Iddrisu Mohammed M. , Nantomah Kwara 
Published: October 2019

This paper presents some new inequalities on Fractional calculus in the context of q-calculus. Fractional calculus generalizes the integer order differentiation and integration to derivatives and integrals of arbitrary order. In other words, Fractional calculus explores integrals and derivatives of functions that involve non-integer order(s). Quantum calculus (q-Calculus) on the other hand focuses on investigations related to calculus without limits and in recent times, it has attracted the interest of many researchers due to its high demand of mathematics to model complex systems in nature with anomalous dynamics. This paper thus establishes some new extensions of Chebyshev and Riemann-Liouville fractional integral inequalities for positive and increasing functions via q-Calculus.

Authors: Kaur Loveleen , Kaur Sukhjeet , Sharma Preeti 
Published: October 2019

Background: Inadequate health and hygiene practices have direct effect on health of the individual, family, communities and nation as a whole. The knowledge about different health and hygiene practices depends largely upon the sources from where we regularly get information. Women tend to be the primary health information seekers for family and for themselves. Therefore there is a need to study their information seeking behaviours.
Aim: The present study was conducted with the objectives to identify the information-seeking behaviour of women regarding household health and hygiene practices, and to ascertain the relationship of information-seeking behaviour of women with their household and socio-economic characteristics.
Methodology: The study was conducted in Ludhiana district of Punjab. Two blocks and two zones were selected purposively from Ludhiana district. Further two villages from each block and two localities from each zone were selected randomly. Twenty five women from each selected village as well as from each locality in the age of 25-50 years were selected on random basis. Thus, a total of 200 women formed the sample for the study and data was collected with the help of an interview schedule.
Results: Information-seeking behaviour was studied in terms of information needs, use of information source and information source evaluation. Findings of the study revealed that majority of the respondents i.e. 59 per cent had low information needs for selected household health and hygiene practices. Informal sources were the most frequently used sources of information whereas use of all information sources by most of the respondents (98%) was found to be low. Around 40 per cent of the respondents never evaluate the source of information while looking for information on household health and hygiene practices. Half of the respondents (50%) had active information-seeking behaviour regarding household health and hygiene practices.
Conclusion: Information-seeking behaviour of the respondents was positively correlated with their education, occupation and mass media exposure while age of the respondents and the family type were negatively correlated with their information-seeking behaviour.

AbstractIn non‐metallic atom‐doped carbonaceous materials, the disparity in electronegativity between the doped constituents and carbon atoms predetermines the bonding topology of covalent bonds and the distribution of electron density. This, consequently, influences the polarization and electron transport behavior within the doped domain and the electromagnetic wave attenuation attributes of the carbonaceous material. However, the influence of covalent bonds formed by doping with weakly electronegative atoms on electron density distribution, polarization effects, and electromagnetic wave attenuation remains uncharted. To address this deficiency, this study fabricates a porous carbonaceous material (NCP) and incorporates boron‐doped atoms to form a material with tunable B─C bonding configurations (B‐NCP). By modulating the B─C bonding configuration and proportion, it is feasible to achieve the synergistic optimization of conductive loss and polarization loss of the B‐NCP specimen. The optimized prototype B‐NCP‐1200 sample displays exceptionally efficient electromagnetic wave absorption capabilities with a minimum reflection loss (RLmin) of −52.03 dB and an effective absorption bandwidth (EAB) of 5.36 GHz. This study presents a conscientious model for comprehending the electromagnetic attenuation mechanisms associated with weakly electronegative atom doping in carbon‐based electromagnetic wave‐absorbing materials.

AbstractLiposomes are established in the clinic as drug delivery system, and can be designed for heat‐triggered drug release. Thermal nanotherapies, like magnetic nanoparticle hyperthermia (MNH) and photothermal therapy (PTT), show great promise for cancer therapy and other diseases, but the great challenge of them is temperature detection. In this study, a thermoluminescent vesicle for real‐time monitoring of PTT and MNH is developed. The temperature sensor is a liposome containing IR780 dyes incorporated in the membrane. For PTT, the liposome is the thermal agent and temperature sensor, while for MNH only the sensor, since the nanoheaters are Mn‐based iron oxide nanoparticles. Mn‐ferrite nanoparticles showed a good response at low field MNH conditions. The photothermal conversion efficiency of the liposomes altered from 11% to 22%. Thermal sensitivity varied from 0.3% to 5.0% and change after freeze‐drying, while repeatability ranged from 0.91 to 0.98. Photostability studies of MNH and PTT with five heat‐cooling cycles confirmed the temperature sensor application. In vivo and post‐mortem studies using the B16F10 murine tumor model are reported. After intratumoral injection of the thermoluminescent vesicle a blue‐like fluorescence peak shift of ≈20 nm is observed, which maintains the thermometry capabilities and reveals remotely the intratumoral temperature during PTT. The results demonstrate that the near‐infrared thermoluminescent liposome is able to real‐time monitoring the thermal therapy.

Published: December 2024

AbstractGoal of this paper is to develop a fully functional parallel Computational Fluid Dynamics (CFD) code that is optimized to run on a single Graphics Processing Unit (GPU). This is achieved by writing the code in FORTRAN and OpenACC (Open Accelerators), providing them with an easily portable, platform independent code. Existing CFD code is significantly modified to allow for parallel asynchronous execution. Also, due to strong recursive dependencies in Tridiagonal Matrix Algorithm (TDMA) solver, it is replaced with Jacobi, which provides fast execution in environments with large number of parallel cores. In this research a computer code for simulation of 2D flow of water through the axisymmetric channel is used as a base for development. The parallel code is executed on GPU, single, and multicore Central Processing Unit (CPU), and the execution times are compared between platforms. Even though that Jacobi solver performs worse on single core computers, compared to its Gauss‐seidel counterpart, it is used to provide a baseline for comparison. In this work, it is shown that computation on finer grids takes less time on GPU than on CPU. The computation time increase with the number of cells in grid on GPU should follow the observed linear trend until the GPUs physical limitations are reached depending on memory size and core count.
Dynamic Scattering‐Channel‐Based Approach for Multiuser Image Encryption
Authors: Taghavi Mohammadrasoul , Marengo Edwin A. 
Published: December 2024

AbstractConventional scattering‐based encryption systems that operate based on a static complex medium which is used by all users are vulnerable to learning‐based attacks that exploit ciphertext‐plaintext pairs to model and reverse‐engineer the scattering medium's response, enabling unauthorized decryption without the physical medium. In this contribution, a new dynamic scattering‐channel‐based technique for multiuser image encryption is developed. The established approach employs variable, dynamic scattering media which are modeled as tunable aggregates of multiple scattering nanoparticles. The proposed system supports multiple users by allowing distinct combinations of scattering matrices for different time blocks, each combined with user‐specific complex‐valued coefficients, enabling the creation of unique, hard‐to‐guess encryption keys for each user. The derived methodology enhances the practical feasibility of multiuser secure communication and storage channels employing scattering media as the encryption mechanism.
Proprioceptive and Exteroceptive Information Perception in a Fabric Soft Robotic Arm via Physical Reservoir Computing with Minimal Training Data
Authors: Wang Jun , Qiao Zhi , Zhang Wenlong , Li Suyi 
Published: December 2024

Over recent decades, soft and reconfigurable robots have rapidly emerged thanks to their ability to interact safely with humans and adapt to complex environments. . However, their softness makes accurate control challenging, requiring high‐fidelity sensing for posture and contact estimation.Traditional camera‐based sensors and load cells have limited portability and accuracy, and they will inevitably increase the robot's cost and weight. In this study, instead of using specialized sensors, only distributed pressure data inside a pneumatics‐driven soft arm are collected and the physical reservoir computing principle is applied to simultaneously predict its kinematic posture (i.e., bending angle) and payload status (i.e., payload mass). Results show that, with careful readout training, one can obtain accurate bending angle and payload mass predictions via simple, weighted linear summations of pressure readings. In addition,analysis show that, to guarantee low prediction errors within 10%, bending angle prediction requires less training data than payload prediction. This reveals that balanced linear and nonlinear body dynamics are critical for the physical reservoir to accomplish complex proprioceptive and exteroceptive information perception tasks. Finally, the method of exploring efficient readout training methods presented here could be extended to other soft robotic systems to maximize their perception capabilities.

ObjectiveHypoxic–ischemic encephalopathy (HIE) is a major cause of perinatal brain injury. Creatine is a dietary supplement that can increase intracellular phosphocreatine to improve the provision of intracellular adenosine triphosphate (ATP) to meet the increase in metabolic demand of oxygen deprivation. Here, we assessed prophylactic fetal creatine supplementation in reducing acute asphyxia‐induced seizures, disordered electroencephalography (EEG) activity and cerebral inflammation and cell death histopathology.MethodsFetal sheep (118 ± 1 days’ gestational age [dGA]; 0.8 gestation) were implanted with electrodes to continuously record EEG and nuchal electromyogram activity. At 121 dGA, fetuses were randomly assigned to sham control (i.v. saline infusion without umbilical cord occlusion [UCO]; SalCon), continuous i.v. creatine infusion (6 mg/kg/h; CrUCO) or isovolumetric saline (SalUCO) followed by UCO at 128 ± 2 dGA that lasted until the mean arterial blood pressure reached 19 mmHg. Brain tissue was collected for histopathology after 72 hours of recovery.ResultsCreatine supplementation had no effects on basal systemic or neurological physiology. UCO duration did not differ between CrUCO and SalUCO. After reperfusion, CrUCO fetuses had improved EEG power and frequency recovery and reduced electrographic seizure incidence (SalUCO, 86% vs CrUCO, 29%) and burden. At 72 hours after UCO, cell death in the cerebral cortex and astrogliosis in the periventricular white matter were reduced in CrUCO fetuses compared with SalUCO.InterpretationCreatine supplementation reduced post‐asphyxial seizures and improved EEG recovery. Improvements in functional recovery with creatine were associated with regional reductions in cell death and astrogliosis. Prophylactic creatine treatment has the potential to mitigate functional indices of HIE in the late gestation fetal brain. ANN NEUROL 2024

Published: December 2024

ABSTRACTPolyhydroxyalkanoates are biodegradable, natural polyesters with the potential to replace petroleum‐based plastics. However, high production costs limit their competitiveness. This study assessed the ability of Halomonas boliviensis, a halophilic bacterium, to synthesize polyhydroxybutyrate (PHB) from an agricultural residue, oil palm empty fruit bunch (OPEFB), in highly saline solutions that minimize contamination risk. OPEFB, containing glucose, xylose, and arabinose, offers a cost‐effective alternative to pure sugar substrates and aids in waste management. PHB production from OPEFB was compared with fermentations using these sugars. H. boliviensis successfully synthesized PHB from all substrates, achieving the highest PHB content from glucose (54.63%), followed by xylose (40.18%), OPEFB (33.59%), and arabinose (33.52%). Glucose in the OPEFB hydrolysate was entirely depleted after 72 h, while xylose showed minimal consumption. This research highlights the potential of using low‐cost carbon sources like OPEFB for PHB production. Future research should focus on optimizing the fermentation process to increase PHB yields, making it a more viable alternative to traditional plastics.
To be Green Is to Live Forever: The Impact of Environmental Information Types on Green Consumption Behavior
Authors: Zhang Huiying , Ding Zhihua , Sun Wenbin , Jiang Xin , Duan Zhaoping 
Published: December 2024

ABSTRACTEnvironmental problems threaten human health and safety. Promoting green consumption has become a vital measure for alleviating environmental problems. How to promote the consumption of green products has also become an important issue for businesses. This paper argues that displaying damaged environmental information to consumers can stimulate their defense mechanism and promote green consumption behaviur. According to terror management theory (TMT), humans have a fundamental desire to live forever. This innate desire motivates people to take action against the threats of death. However, previous studies have reached mixed conclusions about how the threats of death affect pro‐environmental behavior. Through three online between‐subject experiments with Chinese consumers (N = 856), this research illustrates that compared with undamaged environmental information, showing damaged environmental information significantly motivates participants' green consumption behavior, and this effect is mediated by green consumption values. Additionally, when participants were reminded of their heroes, they consumed significantly more green products under the damaged environmental information condition. However, no effect was observed in the group with no hero reminders. The results of this research extend the application of the TMT and mortality salience in green consumption and provide practical suggestions for green product strategies and green policies.
Osteocyte Dendrites: How Do They Grow, Mature, and Degenerate in Mineralized Bone?
Authors: Guerra Rosa M. , Fowler Velia M. , Wang Liyun 
Published: December 2024

ABSTRACTOsteocytes, the most abundant bone cells, form an extensive cellular network via interconnecting dendrites. Like neurons in the brain, the long‐lived osteocytes perceive mechanical and biological inputs and signal to other effector cells, leading to the homeostasis and turnover of bone tissues. Despite the appreciation of osteocytes' vital roles in bone biology, the initiation, growth, maintenance, and eventual degradation of osteocyte dendrites are poorly understood due to their full encasement by mineralized matrix. With the advancement of imaging modalities and genetic models, the architectural organization and molecular composition of the osteocyte dendrites, as well as their morphological changes with aging and diseases, have begun to be revealed. However, several long‐standing mysteries remain unsolved, including (1) how the dendrites are initiated and elongated when a surface osteoblast becomes embedded as an osteocyte; (2) how the dendrites maintain a relatively stable morphology during their decades‐long life span; (3) what biological processes control the dendrite morphology, connectivity, and stability; and (4) if these processes are influenced by age, sex, hormones, and mechanical loading. Our review of long, thin actin filament (F‐actin)‐containing processes extending from other cells leads to a working model that serves as a starting point to investigate the formation and maintenance of osteocyte dendrites and their degradation with aging and diseases.

Published: December 2024

AbstractPerovskite solar cells are promising candidates for low‐cost and efficient photovoltaic markets, but their efficiency is usually limited by the non‐radiative recombination losses at the mismatched interface of perovskite and transport layers. Herein, we show that the band edges of perovskite thin films can be on‐demand engineered by a series of carboxylic‐based self‐assembled monolayers. Experimental and theoretical studies indicate that the functionalized perovskite inherits the polarity of the monolayer with linear dependence of work function on the molecular dipole moments, which enables the management of interfacial charge transport process. Solar cells with 4‐bromophenylacetic acid SAMs achieve about 6.48% enhancement in power conversion efficiency with the champion values over 23%.
Hyena architecture enables fast and efficient protein language modeling
Authors: Zhang Yiming , Bian Bian , Okumura Manabu 
Published: December 2024

AbstractThe emergence of self‐supervised deep language models has revolutionized natural language processing tasks and has recently extended its applications to biological sequence analysis. Traditional language models, primarily based on Transformer architectures, demonstrate substantial effectiveness in various applications. However, these models are inherently constrained by the attention mechanism's quadratic computational complexity, , which limits their efficiency and leads to high computational costs. To address these limitations, we introduce ProtHyena, a novel approach that leverages the Hyena operator in protein language modeling. This innovative methodology alternates between subquadratic long convolutions and element‐wise gating operations, which circumvents the constraints imposed by attention mechanisms and reduces computational complexity to subquadratic levels. This enables faster and more memory‐efficient modeling of protein sequences. ProtHyena can achieve state‐of‐the‐art results and comparable performance in 8 downstream tasks, including protein engineering (protein fluorescence and stability prediction), protein property prediction (neuropeptide cleavage, signal peptide, solubility, disorder, gene function prediction), protein structure prediction, with only 1.6 M parameters. The architecture of ProtHyena represents a highly efficient solution for protein language modeling, offering a promising avenue for fast and efficient analysis of protein sequences.

AbstractBackgroundFu Brick tea (FBT) extract has been demonstrated to lower blood lipids, protect liver, and prevent obesity. Despite these benefits, there are no products on the market that combine FBT with other foods or beverages.ResultIn this study, we developed a novel product by combining FBT with high‐alcohol Jiang‐flavor baijiu, resulting in FBT‐baijiu. High‐performance liquid chromatography–mass spectrometry (HPLC‐MS) analysis revealed that FBT‐baijiu contains health‐promoting alkaloids, including eurocristatine (13.60 ± 0.13 mg/L), (−)‐neoechinulin A (10.26 ± 0.09 mg/L), neoechinulin D (7.89 ± 0.05 mg/L), variecolorin G (6.94 ± 0.05 mg/L), and echinulin (25.46 ± 0.27 mg/L), which are known to be present in FBT. The aroma compounds of the FBT‐baijiu and the base baijiu were analyzed using comprehensive gas chromatography‐olfactometry‐mass spectrometry (GC‐O‐MS) technology. The major volatile compounds of two baijiu samples were identified using relative odor activity values (r‐OAVs) analysis. The FBT‐baijiu showed a significant reduction in ester content, but a remarkable enhancement in aromatic properties. The findings show that combining FBT with baijiu not only offers functional components but also enhances the flavor profile.ConclusionThis study highlights the potential of utilizing FBT as a functional food ingredient or additive, paving the way for the development of new health‐promoting products. © 2024 Society of Chemical Industry.
