Dual selections based knowledge transfer learning for cross-subject motor imagery EEG classification
Authors: Luo Tian-jian 
Published: November 2023

IntroductionMotor imagery electroencephalograph (MI-EEG) has attracted great attention in constructing non-invasive brain-computer interfaces (BCIs) due to its low-cost and convenience. However, only a few MI-EEG classification methods have been recently been applied to BCIs, mainly because they suffered from sample variability across subjects. To address this issue, the cross-subject scenario based on domain adaptation has been widely investigated. However, existing methods often encounter problems such as redundant features and incorrect pseudo-label predictions in the target domain.MethodsTo achieve high performance cross-subject MI-EEG classification, this paper proposes a novel method called Dual Selections based Knowledge Transfer Learning (DS-KTL). DS-KTL selects both discriminative features from the source domain and corrects pseudo-labels from the target domain. The DS-KTL method applies centroid alignment to the samples initially, and then adopts Riemannian tangent space features for feature adaptation. During feature adaptation, dual selections are performed with regularizations, which enhance the classification performance during iterations.Results and discussionEmpirical studies conducted on two benchmark MI-EEG datasets demonstrate the feasibility and effectiveness of the proposed method under multi-source to single-target and single-source to single-target cross-subject strategies. The DS-KTL method achieves significant classification performance improvement with similar efficiency compared to state-of-the-art methods. Ablation studies are also conducted to evaluate the characteristics and parameters of the proposed DS-KTL method.

AimTo investigate the multimodal ultrasound(MMUS) features of cervical lymphadenopathy and to assess its value in the differential diagnosis of benign and malignant cervical lymph nodes.MethodsA retrospective analysis of 169 patients with cervical lymph node enlargement who attended Hangzhou Red Cross Hospital from March 2020 to October 2022. All patients underwent conventional ultrasound (CUS), contrast-enhanced ultrasound (CEUS), and real-time elastography (RTE), and were divided into training set and validation set. Univariate analysis was applied to screen out statistically significant parameters, and CUS model and MMUS model were constructed by multifactorial logistic regression analysis. The receiver operator characteristic (ROC) curve was established, and the area under the curve (AUC) was used to compare CUS model with MMUS model to assess the value of MMUS.ResultsOf the cervical 169 lymph nodes in 169 patients included in the study. The 169 enrolled patients were divided into a training set (132 patients) and a validation set (37 patients). In the training set, univariate analysis showed statistically significant differences in long diameter/short diameter(L/S), border, margin, hilus, dermal medulla boundary, blood flow type, enhancement mode, enhancement type, and RTE score (all p&lt; 0.05). Multifactor logistic analysis showed that L/S, blood flow type, enhancement mode and enhancement type were correlates of malignant lymph nodes (all p&lt; 0.05). The comparison of AUC demonstrated that the discriminative ability of the MMUS model was superior to using the CUS model, both in the training set(p = 0.004) and validation set (p&lt;0.001).ConclusionIn this study, MMUS shows higher diagnostic efficiency than CUS. Ultrasound features such as L/S, blood flow type, mode of enhancement, type of enhancement are helpful in distinguishing benign and malignant lymphadenopathy. The addition of CEUS can greatly improve the sensitivity and specificity of ultrasonic diagnosis of malignant cervical lymph nodes. RTE score is of limited value in the diagnosis of malignant cervical lymph nodes.

IntroductionThis research uses the production method to study aesthetic preference for sequences of human body postures. In two experiments, participants produced image sequences based on their aesthetic preferences, while we measured the visual aesthetic features displayed in the compositions.MethodsIn Experiment 1, participants created static image sequences based on their preferences. In Experiment 2, participants sorted images into apparent motion sequences they preferred to view.ResultsIn Experiment 1, good continuation of successive bodies and body-like objects was the preferred order. In Experiment 2, participants preferred abstract images with local sequential symmetry and human body postures exhibiting global sequential symmetry.DiscussionOur findings are compared to those of previous studies that employed the more widely used method of choice. Our experiments propose novel methods and conceptualizations for investigating aesthetic preferences for human body movement and other types of stimulus sequences.
The physiological basis of leader-follower roles in the dyadic alternating tapping task

Published: November 2023

IntroductionCooperative and collaborative behaviors are important concepts for co-creative communication. One of the key elements for these behaviors is the leader-follower roles in human communication. Leaders are those who maintain their own pace and rhythm, on the contrary, followers are those who follow the pace and rhythm of the other. Well-coordinated leader-follower roles would produce better cooperative and collaborative behaviors, which could promote co-creative communication.MethodsHere, to explore the physiological basis for the leader-follower roles, we conducted the dyadic alternating tapping task with electrocardiographic and electroencephalographic recordings. The task would be stable for modeling human communication in the laboratory because it includes timing control in tens of milliseconds and turn-taking. Given that human communications are complex and constantly fluctuating, this study estimated the degree of leader-follower with the state-space model. This model allowed us to calculate two parameters independently for estimating the degree of leader-follower of each participant: αSelf (degree of one’s tap(n) was explained by one’s tap(n-1)) and αPair (degree of one’s tap(n) was explained by one’s tap (n-1) and pair’s tap (n-1)).ResultsThe result showed heart rate synchronization in the group in which both participants had high αPair. Also, the high-frequency component of heart rate variability was positively correlated with αPair. EEG analyses suggested the deactivation of the mirror neuron system (increasing φ1) in the participants with higher αSelf than lower ones. The activation of the mirror neuron system (increasing φ2) was shown in the participants with lower αPair than higher ones.DiscussionThese data of physiological basis for leader-follower roles could be useful for the constructivist approach to co-creative communication.

BackgroundThe objective of the present study was to evaluate the potential synergistic impact of the combination of fenugreek seeds (FS) and Bacillus-based direct-fed microbials (DFM) on growth performance, intestinal health, and hematological parameters of broiler chickens.MethodsA total of 160 one-day-old (Ross 308) broiler chicks were randomly assigned to a 2 × 2 factorial arrangement, with two levels of FS (0 and 5 g/kg) and two levels of Bacillus-DFM (0 and 0.1 g/kg), with five replicates of 8 birds each.ResultsThe result showed that dietary supplementation of FS at 5 g/kg did not improve the growth performance of broilers but impaired the early growth performance by reducing body weight gain and increasing feed conversion ratio, which was recovered during finisher phase. Dietary supplementation of Bacillus-based DFM at 0.1 g/kg did not affect the performance variables but increased the feed conversion ratio. The interaction of fenugreek seeds and Bacillus-based DFM showed synergistic effects on growth performance during the later stages of production. However, antagonistic effects were observed on the blood parameters and the gut morphology.ConclusionThis study demonstrated that FS and DFM had different effects on the broiler health and production depending on the phase of production. The interaction between FS and DFM revealed synergistic effects on growth performance during the finisher phase, but antagonistic effects on blood parameters and gut morphology. Further studies are needed to elucidate the underlying mechanisms and optimize the dosage and combination of FS and DFM for broiler health and production.

It is well known that both concepts of symmetry and convexity are directly connected. Similarly, in fuzzy theory, both ideas behave alike. It is important to note that real and interval-valued mappings are exceptional cases of fuzzy number-valued mappings (FNVMs) because fuzzy theory depends upon the unit interval that make a significant contribution to overcoming the issues that arise in the theory of interval analysis and fuzzy number theory. In this paper, the new class of p-convexity over up and down (UD) fuzzy relation has been introduced which is known as UD-p-convex fuzzy number-valued mappings (UD-p-convex FNVMs). We offer a thorough analysis of Hermite–Hadamard-type inequalities for FNVMs that are UD-p-convex using the fuzzy Aumann integral. Some previous results from the literature are expanded upon and broadly applied in our study. Additionally, we offer precise justifications for the key theorems that Kunt and İşcan first deduced in their article titled “Hermite–Hadamard–Fejer type inequalities for p-convex functions”. Some new and classical exceptional cases are also discussed. Finally, we illustrate our findings with well-defined examples.

Some aspects of feeding dairy cows and factors affecting the production of high-quality milk suitable for the production of cheeses are considered, in particular, the study of the possibility of full or partial replacement of corn silage with silage from one-year forage crops in the rations. The study was conducted on cows of the Ukrainian black and spotted dairy breed using the method of periods. In the first period (duration 36 days), in addition to the main diet, the animals were fed 25 kg of corn silage, in the second (29 days) - 17 kg of hay from one-year forage crops, and in the third (35 days) - 12 kg of corn silage + 10 kg hay one-year forage crops. The main ration consisted of cereal and legume hay, winter wheat straw, fodder beets, a mixture of grain concentrates and premix. Density, content of dry matter, fat, total protein and casein and its fractional composition, lactose, degree of bacterial contamination, coagulation time of milk under the action of rennet enzyme were determined in milk.
At the end of each period, batches of cheese were produced, the acidity, content of dry matter, fat, protein, degree of maturity were determined in the samples, and their expert evaluation was carried out. Since for the production of high-quality cheeses, milk must meet certain organoleptic parameters, chemical composition, bacterial contamination, the article provides requirements for its quality, as well as recommended rations and composition of premixes. It has been established that for feeding cows in cheese-making areas during the stall period, it is possible to recommend partial or complete replacement of corn silage (as it contains little calcium, which causes slow rennet coagulation of milk) with hay from one-year forage crops, which will lead to improvement of the technological properties of milk (reduction of time coagulation with rennet enzyme for 4-5 minutes, increasing the yield of mature cheese by 7-8%) and will contribute to increasing the casein content in cheese (by 0.12-0.15%), k-fraction of casein (by 1.6-2.1%) and calcium, which are he main indicators of milk suitability for cheese production.

Published: November 2023

The main field of activity of the National Reference Laboratory of Veterinary Drug Residues Control is the expert evaluation of honey safety based on the parameter of antimicrobial drug residues in honey bathes exported from Ukraine to European and American countries. The content of streptomycin and its derivative dihydrostreptomycin is one of the safety parameters for honey, which is investigated by enzyme-linked immunosorbent assay (ELISA). Since 2002, we have developed and proposed the clear scheme to control export honey batches on the content of residual amounts of these aminoglycoside antibiotics by means of Ridascreen® Streptomycin R3104 test kit from R-Biopharm (Germany).
The test kit has been validated at 2.0 and 5.0 µg/kg taking into account the minimum required performance limit (MRPL) or the set reference point for action (RPA) according to European Commission Decision 2002/657/EC and 2021/808/EC. The fitness-for-purpose of the methods was confirmed based on the establishing of main validation parameters for screening methods (technical threshold and cut-off factor) using control (blank) honey samples and spiked with streptomycin standard solutions at the level of ½ MRPL by means of “added – found” approach. The preparation of samples is based on the preliminary purification by the method of solid-phase extraction using C18 columns, which facilitates the purification the sample extract from the influence of matrix components as well as the additional concentration of the analyte.
The article also presents the results of the verification and validation of the Streptomycin NA01904H test kit from Kwinbon Biotechnology (China). The results of the assay of control (blank) honey samples and spiked with streptomycin standard solutions at the level of 2.0 and 5.0 μg/kg are given. Since the advantage of the approved method is the simplicity and rapidity of its performance, so we suggest using it in the laboratory practice of manufacturing and exporting companies.
