On the Quark Scaling Theorem and the Polarisable Dipole of the Quark in a Scalar Field
Authors: Roza Engel
Published: May 2022

In this article the possible impact on the present state of particle physics theory is discussed of two unrecognized theoretical elements. These elements are the awareness that (a) the quark is a Dirac particle with a polarisable dipole moment in a scalar field and that (b) Dirac’s wave equation for fermions, if derived from Einstein’s geodesic equation, reveals a scaling theorem for quarks. It is shown that recognition of these elements proves by theory quite some relationships that are up to now only empirically assessed, such as for instance, the mass relationships between the elementary quarks, the relationship between the bare mass and the constituent mass of quarks, the mass spectrum of hadrons and the mass values of the Z boson and the Higgs boson.
Adaptive Network Automata Modelling of Complex Networks
Authors: Muscoloni Alessandro , Michieli Umberto , Zhang Yingtao , Cannistraci Carlo Vittorio
Published: May 2022

Many complex networks have a connectivity that might be only partially detected or that tends to grow over time, hence the prediction of non-observed links is a fundamental problem in network science. The aim of topological link prediction is to forecast these non-observed links by only exploiting features intrinsic to the network topology. It has a wide range of real applications, like suggesting friendships in social networks or predicting interactions in biological networks.The Cannistraci-Hebb theory is a recent achievement in network science that includes a theoretical framework to understand local-based link prediction on paths of length n. In this study we introduce two innovations: theory of modelling (science) and theory of realization (engineering). For the theory of modelling we first recall a definition of network automata as a general framework for modelling the growth of connectivity in complex networks. We then show that several deterministic models previously developed fall within this framework and we introduce novel network automata following the Cannistraci-Hebb rule. For the theory of realization, we present how to build adaptive network automata for link prediction, which incorporate multiple deterministic models of self-organization and automatically choose the rule that better explains the patterns of connectivity in the network under investigation. We compare Cannistraci-Hebb adaptive (CHA) network automaton against state-of-the-art link prediction methods such as structural perturbation method (SPM), stochastic block models (SBM) and artificial intelligence algorithms for graph embedding. CHA displays an overall higher link prediction performance across different evaluation frameworks on 1386 networks. Finally, we highlight that CHA offers the key advantage to explicitly explain the mechanistic rule of self-organization which leads to the link prediction performance, whereas SPM and graph embedding not. In comparison to CHA, SBM unfortunately shows irrelevant and unsatisfactory performance demonstrating that SBM modelling is not adequate for link prediction in real networks.

Published: May 2022

High purity TiO2 and CuO powders were synthesized by the Pechini method, an inexpensive and easy-to-implement procedure to synthetize metal oxides. The variables of synthesis were the ethylene glycol:citric acid molar ratio and the pH. High reproducibility of the anatase and tenorite phase was obtained for all synthesis routes. The degree of purity of the powders was confirmed by XRD, FTIR, UV-vis absorption and XPS spectra. SEM and TEM images revealed the powders are composed by micrometer grains that can have a spherical shape (only in the TiO2) or formed by a non-compacted nanocrystalline conglomerate. FTIR spectra only vibrational modes associated to the TiO2 or CuO with a nanoparticle behavior. UV-vis absorption spectra revealed the values of maximum absorbance percentage of both systems are reached in the ultraviolet region, with percentages above 83 % throughout the entire visible light spectrum for the CuO system, a relevant result for solar cell applications. Finally, XPS experiments allow the observation of the valence bands and the calculation of the energy bands of all oxides.

Published: May 2022

The new millennium has witnessed a pervasive shift of trend from AC to DC in residential sector. The shift of trend is predominantly due to independent residential solar PV systems at rooftops and escalating electronic loads with better energy saving potential integrated with diminishing prices as well as commercial availability of DC based appliances. DC has ousted AC in generation, transmission, and utilization sectors with the advent of DC based generating systems (e-g solar PV), high voltage DC (HVDC) transmission and the utilization of DC based loads respectively. However, the war of currents (AC vs DC) is still ON as regards to distribution sector. Efficiency is the parameter that once wiped DC out of the power systems scenario as compared to AC-at the time of Tesla and Edison. Therefore, the same parameter is utilized to determine which is better for distribution sector under current conditions; AC or DC? A comprehensive sensitivity analysis considering real load profile is missing in the present body of knowledge. In order to fill that gap, this paper is an attempt to include comprehensive sensitivity analysis of DC distribution system and its simulation-based comparison with AC counterpart considering real load profile. The paper uses Monte Carlo technique and probabilistic approach to add diversity in residential loads consumption and in turn to obtain instantaneous load profile. The paper also presents a futuristic perspective of power electronic converter (PEC) efficiency variation on the efficiency comparison of both AC and DC distribution systems. Since the present body of knowledge generally compares AC and DC distribution based upon assumptions and limited scenarios which results in conflicting outcomes; in contrast, the discoveries of the current examination are useful to reduce the confusions and conflictions regarding which is better at distribution scale; AC or DC?
Optimizing Efficiency and Motility of A Polyvalent Molecular Motor
Authors: Rempel Mark , Emberly Eldon
Published: May 2022

Molecular motors play a vital role in the transport of material within the cell. A family of motors of growing interest are burnt bridge ratchets (BBRs). BBRs rectify spatial fluctuations into directed motion by creating and destroying motor-substrate bonds. It has been shown that the motility of a BBR can be optimized as a function of the system parameters. However, the amount of energy input required to generate such motion and the resulting efficiency has been less well characterized. Here, using a deterministic model, we calculate the efficiency of a particular type of BBR, namely a polyvalent hub interacting with a surface of substrate. We find that there is an optimal burn rate and substrate concentration that leads to optimal efficiency. Additionally, the substrate turnover rate has important implications on motor efficiency. We also consider the effects of force-dependent unbinding on the efficiency and find that under certain conditions the motor works more efficiently when bond breaking is included. Our results provide guidance for how to optimize the efficiency of BBRs.

Authors: Dong Xiuming , Tse Gary , Hao Guoliang , Du Yimei
Published: May 2022

Background: Previous studies have associated slowed ventricular conduction in the arrhythmogenesis mediated by the gap junction and sodium channel inhibitor heptanol in mouse hearts but did not study the propagation patterns that might contribute to the arrhythmic substrate. This study used a multi-electrode array mapping technique, to further investigate different conduction abnormalities in Langendorff-perfused mouse hearts exposed to 0.1 or 2 mM heptanol. Methods: Multi-electrode array recordings were made from the left ventricular epicardium in spontaneously beating hearts, during right ventricular regular 8 Hz pacing or S1S2 pacing. Results: In spontaneously beating hearts, heptanol at 0.1 and 2 mM significantly reduced the heart rate from 314±25 to 189±24 and 157±7 bpm, respectively (ANOVA, P<0.05 and P<0.001). During regular 8 Hz pacing, Mean LATs were increased by 0.1 and 2 mM heptanol from 7.1±2.2 ms to 19.9±5.0 ms (P<0.05) and 18.4±5.7 ms (P<0.05). The standard deviation of mean LATs was increased from 2.5±0.8 ms to 10.3±4.0 ms and 8.0±2.5 ms (P< 0.05), and the median of phase differences was significantly increased from 1.7±1.1 ms to 13.9±7.8 ms and 12.1±5.0 ms by 0.1 and 2 mM heptanol (P<0.05). P5 took a value of 0.2±0.1 ms and was not significantly altered by heptanol at 0.1 or 2 mM (1.1±0.9 ms and 0.9±0.5 ms, P>0.05). P50 was increased from 7.3±2.7 ms to 24.0±12.0 ms by 0.1 mM heptanol and then to 22.5±7.5 ms by 2 mM heptanol (P< 0.05). P95 was increased from 1.7±1.1 ms to 13.9±7.8 ms by 0.1 mM heptanol and to 12.1±5.0 ms by 2 mM heptanol (P<0.05). These changes led to increases in the absolute inhomogeneity in conduction (P5-95) from 7.1±2.6 ms to 31.4±11.3 ms, 2 mM: 21.6±7.2 ms, respectively (P<0.05). The inhomogeneity index (P5-95/P50) was significantly reduced from 3.7±1.2 to 3.1±0.8 by 0.1 mM and then to 3.3±0.9 by 2 mM heptanol (P<0.05). Conclusion: Increased activation latencies, reduced CVs and increased dispersion index of conduction were associated with both spontaneous and induced ventricular arrhythmias.

Authors: Zhang Xi , Wang Hongju , Ren Mingming , He Mengyun , Jin Lei
Published: May 2022

The service conditions of underground coal mine equipment are poor, and it is difficult to accurately extract the fault characteristics of rolling bearings. In order to better improve the accuracy of fault identification of rolling bearings, a fault detection method based on multiscale permutation entropy and SOA-SVM is proposed. First, the whale optimization algorithm is used to select the modal analysis number K and the penalty factor α of the variational mode decomposition algorithm. Then, the vibration signal of rolling bearings is dissolved according to the optimized variational mode decomposition algorithm, and the multi-scale permutation entropy of the main intrinsic mode function is calculated. Finally, the feature values of the matrix are entered into the SVM algorithm optimized by the seagull optimization algorithm to obtain the classification result. The experimental results based on the published rolling bearing datasets of Western Reserve University show that the identification success rate of the proposed method can reach 98.75%. The fault detection of the rolling bearings can be completed accurately and efficiently.

Published: May 2022

Feline panleukopenia (FPL), a highly contagious and frequently fatal disease of cats, is caused by Feline parvovirus (FPV) and Canine parvovirus (CPV). We characterized the diversity of these Carnivore protoparvovirus 1 variants in 18 faecal samples collected from domestic cats with FPL during an outbreak, using targeted parvoviral DNA metagenomics to a mean depth of >10,000 X coverage per site. All samples comprised FPV alone. Compared to the reference FPV genome, isolated in 1967, 44 mutations were detected. Ten of these were non-synonymous, including 9 in non-structural genes and one in VP1/VP2 (Val232Ile), which was the only one to exhibit inter-host diversity, being present in five sequences. There were five other polymorphic nucleotide positions, all with synonymous mutations. Intra-host diversity at all polymorphic positions was low with sub-consensus variant frequencies (SVF) of >1% except for two positions (2108 and 3208) in two samples with SVF of 1.1 – 1.3%. Intra-host nucleotide diversity was measured across the whole genome (0.7 - 1.5%) and for each gene, and was highest in the NS2 gene of four samples (1.2 – 1.9%). Overall, intra-host viral genetic diversity was limited and most mutations observed were synonymous, indicative of a low background mutation rate and strong selective constraints.
Comprehensive Understanding of the Planform Complexity of the Anastomosing River and the Dynamic Imprint of the River’s Flow: Brahmaputra River in Bangladesh
Authors: Sarker Shiblu , Sarker Tanni , Raihan Sarder Udoy
Published: May 2022

The Brahmaputra is one of the largest rivers in the world, ranking fifth in average discharge. As a result, it is heavily braided with various intricate paths in order to dissipate its huge energy. Although this river is normally classed as a braided river, it has recently been classified as an anastomosing river due to its multi-channel features over alluvial plains. Additionally, the Brahmaputra river’s morphology is random in nature as a result of its high flow variability and bank erodibility. Its anastomosing planform changes in response to seasonal water and sediment waves, resulting in a morphology that is extremely complex. The purpose of this study is to examine the Brahmaputra river’s anastomosing planform entropy as a measure of complexity, power spectral density as a measure of fluctuation and their relationship to the energy expenditure as an imprint of flflow rate of river systems on alluvial landscapes.
A Comprehensive Review of Pain Interference on Postural Control: From Experimental to Chronic Pain
Authors: Viseux Frédéric JF , Simoneau Martin , Billot Maxime
Published: May 2022

Motor control, movement impairment and postural control recovery targeted in rehabilitation could be affected by pain. The main objective of this comprehensive review is to provide a synthesis of the effect of experimental and chronic pain on postural control throughout the available literature. After presenting the neurophysiological pathways of pain, we demonstrated that pain, preferentially localized at low back or in the leg induced postural control alteration. While proprioceptive and cortical excitability seems modified with pain, spinal modulation assessment might provide new understanding of the pain phenomenon related to postural control. Literature highlight that the motor control of trunk muscles in patient presenting with low back pain could be dichotomized in two populations, where the first one over-activate trunk muscles, the second one under-activate trunk muscles, and both generating increase of tissues loading. Taking account all this findings, will help clinician to provide adapted treatment for managing both pain and postural control.
Impact of Retardation in the Holstein-Hubbard Model: A Two-Site Calculation
Authors: Marsiglio Frank
Published: May 2022

Eliashberg theory provides a theoretical framework for understanding the phenomenon of superconductivity when pairing between two electrons is mediated by phonons, and retardation effects are fully accounted for. However, when a direct Coulomb interaction between two electrons is also present, this interaction is only partially accounted for. In this work we use a well-defined Hamiltonian, the Hubbard-Holstein model, to examine this competition more rigorously, using exact diagonalization on a two-site system. We find that the direct electron-electron repulsion between two electrons has a significantly more harmful effect on pairing than suggested through the standard treatment of this interaction.

Предлагается вычислительная процедура уточнения положения и формы трехмерных акустических неоднородностей при звуковом зондировании среды. Процедура,
названная вычислительной лупой, основана на быстродействующем алгоритме решения обратной задачи акустического зондирования в областях специальной структуры (трехмерном пространстве, цилиндрической области и др.) с данными (комплексной амплитудой волнового поля), зарегистрированными «в тонком слое». Алгоритм был предложен и изучен авторами в предыдущих работах. Процедура вычислительной лупы состоит в «быстром» решении обратной задачи с помощью
этого алгоритма на начальной сетке в исходной трехмерной области, сужении исходной области до вложенной меньшей новой области, содержащей неоднородности, и решении обратной задачи в этой новой области на новой сетке с тем же
или даже с меньшим числом узлов. Повторяя эту процедуру несколько раз, можно
существенно уточнить положение и форму исследуемых неоднородностей, как бы
«увеличивая» их. Процедура вычислительной лупы работает существенно быстрее,
чем решение обратной задачи на адаптивно измельчаемых трехмерных сетках в
исходной области. Это позволяет легко реализовать процедуру на персональных
компьютерах (ПК) средней производительности. Предлагается способ численной
оценки качества уточнения положения и формы изучаемых неоднородностей, основанный на применении гистограмм. Представлен ряд численных модельных экспериментов на ПК по использованию вычислительной лупы в цилиндрической области. В их числе: анализ качества уточнения положения и формы с помощью гистограмм при решении обратной задачи с точными и зашумленными данными, влияние усреднения зашумленных данных на определение положения и формы, эксперименты по оценке разрешающей способности вычислительной лупы и др. Время
работы вычислительной лупы в каждом из этих трехмерных численных экспериментах составило около 10 сек.

Подробно рассмотрен 1D2V случай плоской симметрии, для которого построен численный алгоритм исследования решений гибридных уравнений электромагнитной гидродинамики, базирующийся на методе макрочастиц. Дано решение ряда принципиальных вопросов: вычисление средних величин, интерполяция, построение начального распределения макрочастиц, выбор граничных условий для электрического поля и т.д. Приведены результаты расчeтов с учeтом и
без учeта индукционных полей в плазменном двигателе. Влияние индукционных
полей, генерируемых плазменными токами, на процессы в стационарном плазменном двигателе и роль инерции электронов ранее не изучались, и полученные результаты являются оригинальными. В частности, предложена новая нетрадиционная схема расчeта электрического поля на базе обобщeнного закона Ома, который
в электромагнитной гидродинамике сводится к краевой задаче для эллиптической

Published: May 2022

The study of “water-energy-carbon” has always been an important theme in natural science. With the concern of climate change, the relationship between water and carbon has also attracted attention. China has published several policies for the water conservation, and it has begun to explore the policy transform of the water fee into water tax, which will become a key economic measure for water management. In the background of the carbon reduction, the policy may influence both the water system and the carbon system. This study mainly analyzes how future water tax affects the climate change in China by using the macroeconomic model named the computable general equilibrium model (CGE model). Two scenarios with different tax ratios have been set, and policies are implemented among different sectors. The policy will not only directly impact these industrial sectors but also indirectly impact other sectors through the economic system, which will finally do tiny contribution to the long-term climate change. The working mechanism was discussed, and policy implications were proposed at last. Firstly, China should pay attention to the impacts of macropolicies on CO2 reduction as it has set the goal of peaking carbon emissions and achieving carbon neutrality. Secondly, more study needs be carried out for the mechanisms of the “water-energy-carbon” process from the macroeconomic perspective for combing the climate change.

Authors: Adair Olivia , McFerran Ethna , Owen Tracy , McKee Christine , Lamrock Felicity , Lawler Mark
Published: May 2022

Background: Colorectal Cancer (CRC) is becoming an increasing health problem worldwide. However, with the help of screening, early diagnosis can reduce incidence and mortality rates. To elevate the economic burden CRC can cause, cost-effectiveness analysis (CEA) can assist healthcare systems to make screening programmes more cost-effective and prolong survival for early-stage CRC patients. This review aims to identify different CEA modelling methods used internationally to evaluate CRC. Methods: This review will systematically search electronic databases which include MEDLINE, EMBASE, Web of Science and Scopus. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidance recommendations will design the review and the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement will be used to extract relevant data from studies retrieved. Two reviewers will screen through the evidence using the PICOS (Participant, Intervention, Comparators, Outcomes, Study Design) framework, with a third reviewer to settle any disagreements. Once data extraction and quality assessment are complete, the results will be presented qualitatively and tabulated using the CHEERS checklist. Discussion: The results obtained from the systematic review will highlight how different CRC screening programmes around the world utilise and incorporate health economic modelling methods to be more cost-effective. This information can help modellers develop CEA models which can be adapted to suit the specific screening programmes.Systematic Review Registration: PROSPERO CRD42022296113

Background: The high prevalence of dysphagia among Alzheimer’s diseases (AD) has incurred many negative impacts. Therefore, effective and practicable dysphagia treatment are needed. As a fundamental rehabilitation of dysphagia, swallowing muscles exercises have received increased attention. Stepwise swallowing training (SST), integrated all swallowing organs movement, is expected to improve swallowing dysfunction among AD patients. By using randomized controlled trial design, the proposed study conducts a multi-center research to evaluate the effectiveness of SST program among AD patients.Methods: A multi-center randomized controlled trial, with a 4-week follow-up period after intervention, will be conducted among psychiatric hospitals in Guangdong, China. Participants in the control group will be assigned to routine dysphagia care, participants of the intervention group will undergo the same nursing care while additionally receive SST program. The SST program includes five sections of swallowing organs training: lip movement, facial movement, tongue movement, mandibular movement, and neck movement, respectively. Primary outcomes evaluate the swallowing function, including Water Swallowing Test (WTS) and Standard Swallowing Assessment (SSA). Secondary outcomes aim at measuring the improvement of negative impacts of dysphagia, including eating behavior, ability of daily activity, and nutritional status. Data will be collected at baseline (T0), at 2 weeks (T1, intervention completed), and at 4 weeks after intervention (T2, follow-up).Discussion: This study will offer trial-based evidence of the effectiveness of SST in relieving dysphagia among AD patients. SST program is expected to improve both the swallowing function and reduce negative impacts of dysphagia, with exploration of acceptability in SST program.Trial Registration: Chinese Clinical Trail Registry, ChiCTR2200056481.

Lactuca georgica is a wild species belonging to the secondary lettuce gene pool: additional evidence, obtained by KASP genotyping
Authors: Beharav Alex
Published: May 2022

This work evaluated the genetic relationships between 442 single-seed descent (SSD) accessions, representing eight Lactuca spp., including five wild Lactuca relatives (WLRs) (Lactuca georgica, L. altaica, L. saligna, L. serriola, L. aculeata), L. tuberosa, L. undulata, and the domesticated lettuce, L. sativa, most of them (437) representing a core subset of the Institute of Evolution's Wild Lettuce Gene Bank (IoE's WLGB) collection. The analysis was performed by profiling 115 single-nucleotide polymorphism (SNP) markers by means of the fluorescent KASP genotyping assay. The KASP marker fragments were scored as either allele “A” or allele “B”, that were used across analyses as bi-allelic data, but included relatively a lot of U-scores, i.e., an absence of the specific sequence, that were treated as missing data. Often U-scores were specific for a certain species. Data analysis of the five WLRs showed that allele frequencies of 103 (97.2%) out of 106 differentiating loci varied significantly among the species, where 59.7% of the KASP marker diversity was between species. A neighbor-network analysis between samples belonging to the five WLRs and a single L. sativa cv. clearly clustered all 430 samples in accordance with their taxonomic determination. The results obtained here via multiple complementary analyses of large natural populations and individuals for germplasm variation, question assignment of L. georgica to the primary lettuce gene pool (LGP1). Together with our previous results obtained using TRAP markers, and hybridization experiments, we conclude that L. georgica is a constituent of the LGP2.

Published: May 2022

Plant gums and their derivatives are widely used in the food industry. One of the native plants of West Azerbaijan province is Opopanax (Prangos ferulacea). Many studies have been done on different parts of Opopanax but so far no studies have been done on the characteristics and application of gum extracted from Opopanax. Therefore, the aim of this study is to extract gum from the roots of this plant and to investigate its qualitative and rheological properties. For this purpose, gum extraction from the root of Opopanax was done using ultrasound in two methods with three variables of extraction time (10, 35, and 60 minutes), extraction temperature (in the water extraction 40, 65, and 90; and in the sonication 30, 50, and 70°C) and solid to water ratio (10, 25, and 40%). The extracted gum samples were examined and optimized for physicochemical properties; After that, two optimized gum samples were produced and then examined for physicochemical, rheological, and structural properties and monosaccharide compounds. The results showed that the two extracted gum samples according to the optimization process had a maximum extraction efficiency of 45.63% in the water extraction and 60.947% in the sonication. According to the studies performed on the two samples of optimized gum, there were no significant differences in terms of physicochemical properties (moisture, fat, protein, ash and carbohydrates) (p > 0.05). Study of the antioxidant activity of the gum extracted in the sonication in which a lower temperature was used, showed a higher inhibition percentage of DPPH radical (53.92 ± 0.02). In the identification of monosaccharide compounds by HPLC, nine monosaccharide compounds were identified, the most monosaccharides were glucose and rhamnose and the least compounds were mannose and sorbitol. In the study of rheological behavior, two gum samples of Opopanax root showed the viscoelastic behavior in the samples and the formation of a weak gel structure. Also with the decrease of viscosity, they presented thinning behavior with time (pseudoplastic). In the current study, using successful ultrasound waves, gum was extracted from the roots of the plant. This gum can be used as a functional and additive hydrocolloid in the food industry.
