Air traffic control forgetting prediction based on eye movement information and hybrid neural network
Authors: Jin Huibin , Gao Weipeng , Li Kun , Chu Mingjian
Published: August 2023

Control forgetting accounts for most of the current unsafe incidents. In the research field of radar surveillance control, how to avoid control forgetting to ensure the safety of flights is becoming a hot issue which attracts more and more attention. Meanwhile, aviation safety is substantially influenced by the way of eye movement. The exact relation of control forgetting with eye movement, however, still remains puzzling. Motivated by this, a control forgetting prediction method is proposed based on the combination of Convolutional Neural Networks and Long-Short Term Memory (CNN-LSTM). In this model, the eye movement characteristics are classified in terms of whether they are time-related, and then regulatory forgetting can be predicted by virtue of CNN-LSTM. The effectiveness of the method is verified by carrying out simulation experiments of eye movement during flight control. Results show that the prediction accuracy of this method is up to 79.2%, which is substantially higher than that of Binary Logistic Regression, CNN and LSTM (71.3%, 74.6%, and 75.1% respectively). This work tries to explore an innovative way to associate control forgetting with eye movement, so as to guarantee the safety of civil aviation.
Comparison of genome replication fidelity between SARS-CoV-2 and influenza A virus in cell culture
Authors: Kawasaki Yoshiko , Abe Haruka , Yasuda Jiro
Published: August 2023

Since the emergence of COVID-19, several SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) variants have emerged and spread widely. These variants are produced through replication errors of the viral genome by viral RNA-dependent RNA polymerase (RdRp). Seasonal epidemics of influenza are also known to occur because of new variants of influenza A virus (IAV), which are generated by the introduction of mutations by viral RdRp with low fidelity. Variants with different antigenicities appear because of mutations in envelope glycoproteins. In this study, we calculated and compared the mutation rates in genome replication of IAV and SARS-CoV-2. Average mutation rates per passage were 9.01 × 10–5 and 3.76 × 10–6 substitutions/site for IAV and SARS-CoV-2, respectively. The mutation rate of SARS-CoV-2 was 23.9-fold lower than that of IAV because of the proofreading activity of the SARS-CoV-2 RdRp complex. Our data could be useful in establishing effective countermeasures against COVID-19.
Past and future adverse response of terrestrial water storages to increased vegetation growth in drylands
Authors: Liu Kai , Li Xueke , Wang Shudong , Zhou Guangsheng
Published: August 2023

The response of terrestrial water storages to dryland vegetation growth remains poorly understood. Using multiple proxies from satellite observations and model outputs, we show an overall increase (decrease) in vegetation growth (terrestrial water storages) across drylands globally during 1982–2016. Terrestrial water storages in greening drylands correlate negatively with vegetation growth, particularly for cropland-dominated regions, and such response is pronounced when the growth rate of vegetation productivity is high. Reduction in terrestrial water storage is dominated by precipitation and evapotranspiration variability rather by than runoff. We predict reduction in terrestrial water storage of 41–84% by 2100, accompanying expansion of drylands by 4.1–10.6%. Our findings, which indicate sustained adverse response of terrestrial water storage to vegetation growth in drylands, highlight the need for concerted planning for balanced ecological restoration, agricultural management, and water resource utilization that will affect 5.17 billion people, 64% of whom live in developing countries.

Aberrantly expressed onco-mucin 16 (MUC16) and its post-cleavage generated surface tethered carboxy-terminal (MUC16-Cter) domain are strongly associated with poor prognosis and lethality of pancreatic (PC) and non-small cell lung cancer (NSCLC). To date, most anti-MUC16 antibodies are directed towards the extracellular domain of MUC16 (CA125), which is usually cleaved and shed in the circulation hence obscuring antibody accessibility to the cancer cells. Herein, we establish the utility of targeting a post-cleavage generated, surface-tethered oncogenic MUC16 carboxy-terminal (MUC16-Cter) domain by using a novel chimeric antibody in human IgG1 format, ch5E6, whose epitope expression directly correlates with disease severity in both cancers. ch5E6 binds and interferes with MUC16-associated oncogenesis, suppresses the downstream signaling pFAK(Y397)/p-p70S6K(T389)/N-cadherin axis and exert antiproliferative effects in cancer cells, 3D organoids, and tumor xenografts of both PC and NSCLC. The robust clinical correlations observed between MUC16 and N-cadherin in patient tumors and metastatic samples imply ch5E6 potential in targeting a complex and significantly occurring phenomenon of epithelial to mesenchymal transition (EMT) associated with disease aggressiveness. Our study supports evaluating ch5E6 with standard-of-care drugs, to potentially augment treatment outcomes in malignancies inflicted with MUC16-associated poor prognosis.
Cognitive gripping with flexible graphene printed multi-sensor array
Authors: Mukherjee Tania , Gupta Dipti
Published: August 2023

Robotics for task simplification of domestic, household, workplace and other assistive activities require efficient robots with decision-making capabilities. Here we report a fully printed graphene-based capacitive multi-sensor array (CAPSENSAR) employed in a cognitive robotic gripper (COGBOT) for decision-making operations. The CAPSENSAR created a contactless capacitive impression of the gripped object surface to determine the optimum gripping pressure. The controlling unit of the COGBOT was associated with an algorithm to address potential breakage. If slippage was detected via the array, the grip pressure was revised to reduce the possibility for damage. This facilitated slippage-free and damage-resistant gripping of the target objects without user interference. Array fabrication was straightforward using a customizable electrode design with cost-effective and biocompatible materials.
Introduction

Published: August 2023

One of the most intricate bodily processes is the healing of dermal wounds. Multiple cell types with different roles during the phases of hemostasis, inflammation, growth, re-epithelialization and remodelling must be coordinated in both space and time. Phenotypic and functional variability within a few of these cell types have been discovered as a result of the development of single-cell technologies. Rare stem cell subgroups that are unipotent in the undamaged state but become multipotent after skin injury have also been found to exist within the skin. Dermal wound healing is adversely affected by changes in the microenvironment, which include modifications to mechanical forces, oxygen levels, chemokines, extracellular matrix and growth factor production. The methods and treatments for cutaneous wound care, which are novel but becoming more and more popular, are the main topic of this book. Dermal wound care has been around for a while, but is just now becoming more popular among doctors.
Antibacterial and Antifungal Materials
Authors: Hosseini S. M. , Morovati Moez N. , Arabestani M. R.
Published: August 2023

Over recent decades, the morbidity and mortality rate of infectious diseases with bacterial and fungal etiology has increased greatly. This may be due to overuse and abuse of prescription antifungal and antibacterial drugs, which causes organisms to gradually acquire the ability to overcome the drug and develop resistance. Moreover, many antimicrobials display a variety of toxicities for human use. Also, multiple resistance of bacteria to different antibiotics has caused many problems. Nowadays, the greatest challenges in hospital burn wards is Pseudomonas infection as this bacterium has become multiply resistant to commercial antibiotics. So that, the World Health Organization stated the most concerning condition in the 21st century relates to the most pan-drug-resistant strains, which are extremely resistant to most current antibiotics. As an example, Acinetobacter baumannii and Pseudomonas aeruginosa have the first ranks of antibiotic discovery priority as strains are resistant to the Carbapenem family. Also, annual rises to the number of drug resistant strains of pathogens such as Mycobacterium tuberculosis, HIV and malaria parasites are considered to be major concerns. Despite the efforts conducted in antimicrobial discovery, multiple-drug-resistant strains are still increasing much faster than novel antimicrobial innovations, resulting in demand for new antimicrobial therapies with the hope of overcoming infectious disease. This chapter will review most traditional and novel antibacterial and antifungal materials from the first discoveries to the latest antimicrobial techniques.

Structural Characterization of Porous Organic Materials
Authors: Malik Pratibha , Maity Tanmoy , Haldar Ritesh
Published: August 2023

Porous organic materials (POMs) feature intrinsic porosity, which can be related to porous sponges and charcoal. The void space geometry and chemical functionality of these materials can be designed using cross-linking chemistry and the self-assembly process. To make use of these porous materials, detailed insight into the pore structure, structural order, and morphology is necessary. In this chapter, we evaluate the possible characterization methods of these state-of-the-art porous structures, crystalline and amorphous. As the design principles and advantages of these materials over the contemporary porous materials are not within the scope of this chapter, we chose benchmark and earliest known examples of POMs to illustrate the characterization techniques and their developments.

Exploring Alternative Methods to Reduce Milk Flow Rate From Infant Bottle Systems: Bottle Angle, Milk Volume, and Bottle Ventilation
Authors: McGrattan Katlyn Elizabeth , Jansen Gregory Paul , Barrera Jennifer Meraz , Beckstrand Michael
Published: August 2023

Purpose:

Modifying milk flow rate is a common pediatric dysphagia treatment. Though past investigations have demonstrated how this can be achieved using bottle nipples, little is known about the impact of other bottle modifications. The objective of this investigation is to demonstrate how bottle vent, bottle position, and volume of milk alter bottle pressures and milk flow.

Method:

A Dr. Brown's bottle filled with formula was secured to a retort stand and inverted to allow milk to free flow from a Level 1 nipple. Milk flow rate and bottle pressures were calculated under three conditions: (a) with and without a vent in place; (b) with varying volumes of milk (1–4 oz); and (c) in horizontal, semi-inverted, and completely inverted positions. Differences between flow rates under the conditions were tested using repeated-measures analysis of variance.

Results:

Upon inversion, milk dripped from both vented and unvented bottles. Dripping continued throughout the 20-min testing period in the vented bottle; however, as air pressure and hydrostatic pressure declined (
p
< .01) in the unvented bottle, milk flow slowed and eventually ceased (
p
< .001). As angle of bottle inversion increased, hydrostatic pressure and milk flow rate had corresponding increases as well (
p
< .001). Hydrostatic pressure increased an average of 1.4 ± 0.12 mm Hg per additional ounce of formula that was added to the bottle, with corresponding increases in milk flow rate observed (
p
< .001).

Conclusions:

Milk flow rate can be altered by feeding conditions outside of bottle nipples alone. Future work examining the clinical significance of these modifications is warranted to determine optimal interventions.
SDAUNet: A simple dual attention mechanism UNet for mixed noise removal

Published: August 2023

Convolutional neural networks (CNNs) have demonstrated impressive results in additive white Gaussian noise removal due to their strong fitting ability. However, their performance in mixed noise removal remains unsatisfactory, primarily due to their limited receptive field that focuses only on the local features of images and disregards global information. To ameliorate this issue, recent state‐of‐the‐art approaches employ attention mechanism (AM) to capture the global information. However, most AM based methods still suffer from low computational efficiency. In this paper, a novel model named simple dual attention mechanism UNet (SDAUNet) for mixed noise removal is proposed. In SDAUNet, the UNet architecture is used to gradually acquire multi‐scale image features and provide a more comprehensive and accurate representation of the image features than other CNNs. A simple dual attention convolutional block is presented to acquire the global image features that can successfully capture image details with a low burden. The experimental results demonstrate that the SDAUNet model can achieve better measurement metrics and visual performance than other state‐of‐the‐art methods.

Medical therapists often manage medications to improve therapeutic outcomes for their patients. For senior patients who take multiple drugs to manage various conditions, medication adherence is critical. To provide an immersive and engaging medication reminder experience, the authors propose i‐Ware, a smart wearable m‐Health (mobile health) device. The system's hardware and software were co‐designed to meet non‐functional requirements. The model reminds patients to take their medication, and the augmented reality goggles aid those who struggle to manage their medicine. The navigation features help users find their way home, and the audio feature reads out the date and time, useful for patients with low vision. The i‐Ware system has the potential for real‐world application and can significantly improve medication adherence. As an AR‐enabled medicine reminder, i‐Ware is an innovative solution for medication management in senior patients.

Published: August 2023

One of the main indicators of high-quality sowing of seeds of agricultural crops is their uniform distribution along the length, because the main influence is exerted by the sowing apparatus. In the proposed work, the sowing of seeds of grain crops using a coil seeding machine is considered as an object of research. As a subject of research, the dependences of the uniformity of the distribution of seeds along the length of the furrow on the unevenness of the specific working volume of the coil, the rotation frequency of the blower of the pneumatic seeder and the seeding rate are considered. The aim of the work is to improve the uniformity of the distribution of the area of nutrition that falls on each plant with an ordinary method of sowing winter wheat. The paper presents the results of theoretical prerequisites for determining the working volume of the seeding coil, the results of field experiments of the seeding apparatus using coils with different geometric characteristics. The analysis of the uniformity of seed distribution using regression analysis and Bayesian networks is carried out. The resulting determination coefficient of 0.82 allows us to conclude that the resulting mathematical model can be used for practical purposes. It is noted that the proposed cellular-honeycomb seeding coil stands out qualitatively among the grooved and grooved-screw.

The article presents the results of a model experiment to study the effect of a liquid plant growth stimulant Seaweed Seychelles on the germination of seeds of microgreen of coral radish (Raphanus sativus var. Sativus). Seaweed is a source of natural plant growth hormones. Each of them is an important biostimulant of health. Auxin is known for its positive effect on the roots. It is used in synthetic hormones for rooting. Seaweed contains more than 60 trace elements and nutrients. First of all, it is potassium, nitrogen, phosphorus, iodine, manganese, molybdenum and boron. In the course of this study, it was found that the liquid plant growth stimulant Seaweed Seychelles significantly increases the germination of seeds of coral radish (Raphanus sativus var. Sativus). Seed germination was 98%. The phosphorus content increased by 14.5%, and the nitrogen content by 30%, the pH remained neutral. Seaweed Seychelles liquid stimulant actively affects radish sprouts and contributes to an increase in growth rate and quality.

This paper considers one of the key production problems associated with the production of environmentally friendly particle boards (reinforced wood particle board) based on aminoformaldehyde binders that meet all the necessary requirements of modern standards. One of the promising solutions to this problem can be the use of reactive technological additive, which has a complex action: catalyst for curing the binder and acceptor of free formaldehyde contained in the binder. The proposed action will allow to produce boards with high physical and mechanical characteristics and minimum content of free formaldehyde, which can indicate a high quality of the products and expand the scope of these composite materials, including production of furniture for home and children's institutions.

One of the important issues in the study of composite materials are microdefects and their accumulation in the binder. Cracks that occur in the transverse directions of the layers are considered to be the most common macrodefect. During cracking, the elastic modulus and shear modulus decrease. This article discusses the issue of obtaining calculation formulas that take into account the accumulation of damage, taking into account cracks in the layers and interlayer cracks on the example of the wing joint with the center section.

In modern conditions, most soils are exposed to erosion processes. In this regard, it is necessary to control the amount of dust particles in the surface layer of the soil. Fine tillage with flat-cutting working bodies solves this issue by creating a finely cloddy soil structure of the upper fertile layer. The article considers the developed original design of a flat cutter for fine tillage. The results of experimental studies on the determination of agrotechnical indicators for the treated background and untreated stubble background are presented. In the course of the research, such indicators were established as: the average actual working depth, the standard deviation of the working depth from the given one, the coefficient of variation in the working depth, crumbling of the soil by the working bodies, the moisture content inside the reservoir, the number of erosion-dangerous particles in the surface soil layer. As a result of the research, it was found that the flat cutter qualitatively performs the specified depth of tillage with an acceptable deviation, the ridge size is in the range of 3.6-3.9 cm, which is allowed by agrotechnical requirements, the number of lumps up to 25 mm in size after the passage of the working body is 82-85% . With shallow tillage with a flat cutter, the removal of wet layers to the soil surface is not observed. The flat cutter can function qualitatively on an untreated stubble background as part of a combined unit that is not equipped with disk working bodies.
