Robotic rehabilitation of upper-limb after stroke - Implementation of rehabilitation control strategy on robotic manipulator

Globally, stroke is one of the main causes of permanent neurological damage [18]. Partial or total paralysis of the extremities is the most common complication, with paralysis in upper-limbs being the most prevalent. Efficient and available rehabilitation therapy is essential for the patient’s recovery process. Traditional physical therapy is a resource intensive and commonly used approach. Research on robotic rehabilitation aims to provide a viable rehabilitation tool. The main objective of this master thesis is to design and implement a safe real-time control system on an industrial six-axis manipulator with an external force/torque sensor for robotic upper-limb rehabilitation of stroke patients. The chosen approach is to implement control strategies directly in the tool frame of the manipulator. This is achieved by utilizing the UR5 from Universal Robot and the Mini45 F/T sensor from ATI Industrial Automation. Two verification test are chosen based on activities of daily life (ADL). The best low-level control strategy is achieved by indirect force and torque control through a joint velocity interface. The UR5 firmware operates with an unknown internal controller. An external controller is designed incrementally to investigate the unknown system dynamics and find the best possible low-level performance. Numerous safety mechanisms are added to the external controller. Four high-level control strategies are developed and implemented. Three main safety-related challenges with robotic rehabilitation are identified. Two of them are related to and solved by the external force/torque sensor. The third challenge is related to the self-collisions inside the workspace of the UR5 manipulator. This challenge is also applicable to all six-axis robot manipulators. The three challenges are analyzed and solved with a safety-oriented approach. The safety and functionality of the robotic rehabilitation system are experimentally verified. The behaviour of the rehabilitation modes is analyzed and discussed based on raw data and video recordings. The conclusion is that robotic upper-limb rehabilitation of stroke patients utilizing the UR5 manipulator and the Mini45 F/T sensor is safe and feasible.
Data-Driven Detection and Assessment for Urban Railway Transit Driver Fatigue in Real Work Conditions

Fatigue among urban railway transit (URT) drivers affects their performance and is a contributing factor in many railway accidents and incidents. This paper attempts to develop a robust fatigue detection system for URT drivers. An experimental study was conducted in actual work conditions, involving 198 professional URT drivers, to provide authentic and representative data. Fatigue scores based on the Karolinska Sleepiness Scale were used as the ground truth, and heart rate variability (HRV) data were collected using wearable photoplethysmography (PPG) sensors under actual working conditions. An extensive statistical analysis found that continuous working hours were a major factor in driver fatigue. HRV features were able to differentiate various fatigue levels. Four classifiers (k-nearest neighbors, Naive Bayes, support vector machines, and random forests) were trained to detect fatigue in real time for binary and three-class fatigue classifications, respectively. For the binary classification, the best performance was achieved by the random forest classifier using the corrected feature set as input with an accuracy of 92.5%. However, the accuracy dropped by 8 to 27 percentage points for the three-class classification. Moreover, the research found that the corrected feature set circumventing inter-individual variability in HRV could improve the performance of fatigue classifiers. The findings from this research could contribute to developing a robust and real-time URT driver fatigue detection system and improve current URT operational safety regulations.
Effects of Raw and Pasteurized Camel Milk on Metabolic Responses in Pigs Fed a High-Fat Diet

Simple Summary Camel milk (CM) contains insulin-like peptides and is high in vitamin C, vitamin E, and antioxidants. Previous studies in diabetic mice and humans have demonstrated a positive impact of CM consumption on glycemic balance, potentially greater than that observed for the consumption of bovine milk. Thus, CM may be a viable therapeutic treatment for diabetic humans, although the mode of action of these effects are not yet understood. This experiment used a high-fat diet as a monogastric model to examine the effect of CM consumption (raw or pasteurized) on some key blood metabolic markers and examined responses to an in vitro glucose tolerance test. While the results are preliminary given the low number of animals, this experiment suggested that CM can improve glycemic control, potentially via a tighter control of insulin effectiveness and/or uptake. Abstract Evidence suggests that camel milk (CM) can have insulin-like actions, although the mode of action is not understood. Using the pig as a monogastric model, this pilot experiment examined the effects of CM consumption on metabolic responses to an in vitro glucose tolerance test (IVGTT). Twenty female Large White × Landrace pigs were individually housed for 6 wks and randomly allocated to one of the following four diets (fed ad libitum; n = 5): control (Con); high fat (HF; ~16% fat); raw CM (the HF diet plus 500 mL CM/ day); or pasteurized CM (PCM). Blood samples were collected on two occasions (weeks 2 and 5). At week 6, the pigs were fitted with an ear vein cannula and the following day an in vitro glucose tolerance test (IVGTT) was conducted (0.3 g/kg BW glucose). Plasma fatty acids and cholesterol concentrations were greater in the pigs fed the HF diet and greatest in those fed CM, while there was no effect of diet on insulin concentrations. The pigs fed CM tended to have a reduced peak insulin (p = 0.058) and an increased glucose nadir (p = 0.009) in response to the IVGTT. These preliminary results tend to support the hypothesis that feeding CM can improve glycemic control in pigs.
Comparative analysis of the aerodynamic performance of trains and dynamic responses of catenaries for windbreak walls with different heights under crosswind

Due to the deterioration of the crosswind-protection performance of the original earth embankment windbreak walls on the train with increased speed, researching the influence of the heightened windbreak walls on aerodynamic performances of trains as well as the protection of the catenary is necessary for optimizing the windproof performance. The improved delayed detached eddy simulation based on the shear stress transport (SST) κ-ω turbulence model was employed to simulate flow structures. Furthermore, the effect on the displacement of the catenary was investigated using the finite element method (FEM). The numerical case was validated against the field tests. The results show that the aerodynamic performances of the train were improved as the windbreak wall was heightened by 0.5 m. Whereas, further heightening the windbreak wall worsened the aerodynamic performance. When the windbreak wall was heightened by 0.5 and 1 m, the wind speed of the catenary was reduced by 31.17% and 53.87%, and the displacement of the catenary was reduced by 48.09% and 74.11%, respectively, compared with that of the original windbreak wall. These results reveal that the wind-protection performance on the train and catenary can be both improved by reasonably heightening windbreak walls.
Feeling Luxe: A Topic Modeling × Emotion Detection Analysis of Luxury Hotel Experiences

As the luxury market and associated experiential consumption continues to rise, the hospitality management literature lags somewhat behind practice in examining luxury experiences. This research presents an exploratory analysis of luxury hotel experiences via the approach of topic modeling and emotion detection in online luxury hotel reviews. Results demonstrate that “people” and “product—activity & wellness” aspects of luxury hotel experiences tend to be positively associated with online review ratings. The “product—food & beverage” and “physical evidence and place” aspects may produce mixed effects on rating levels. Finally, the “process” and “price and promotion” aspects tend to be negatively associated with online review ratings. Findings further reveal that such effects function via the mediation paths of various categories of discrete emotions. These results offer enriching insight for hospitality management research and practice regarding luxury hotel experiences.

Binary Mixtures of Imidazolium-Based Protic Ionic Liquids. Extended Temperature Range of the Liquid State Keeping High Ionic Conductivities

Binary mixtures based on the two protic ionic liquids 1-ethylimidazolium triflate ([C2HIm][TfO]) and 1-ethylimidazolium bis(trifluoromethanesulfonyl)imide ([C2HIm][TFSI]) have been investigated, with focus on phase behavior, ionic conductivity, and intermolecular interactions as a function of composition (χ TFSI indicating the mole fraction of the added compound). It is found that on addition of [C2HIm][TFSI] to [C2HIm][TfO], the melting temperature is first decreased (0 < χ ≤ 0.3) and then suppressed (0.3 < χ ≤ 0.8) resulting in mixtures with no phase transitions. These mixtures display a wide temperature range of the liquid state and should be interesting for use in devices operating at extreme temperatures. The ionic conductivity does not vary significantly across the composition range analyzed, as evidenced in the comparative Arrhenius plot. The activation energy, E a , estimated by fitting with the Arrhenius relation in a limited temperature range (between 60 and 140 °C) varies marginally and keeps values between 0.17 and 0.21 eV. These marginal differences can be rationalized by the initially very similar values of the two neat protic ionic liquids. Vibrational spectroscopy, including both Raman and infrared spectroscopies, reveals weakening of the cation–anion interactions for increasing content of [C2HIm][TFSI], which is reflected by the blue shift of the average N-H stretching mode and the red shift of the S-O stretching mode in the TfO anion. These trends correlate with the higher disorder in the mixtures observed by DSC and are evidenced by the decrease and suppression of the melting temperature as the amount of [C2HIm][TFSI] is increased.
Effect of Temperature on Space Charge Distribution of Oil–Paper Insulation under DC and Polarity Reversal Voltage

The electric field distortion caused by space charge is an important factor affecting the operation reliability of oil–paper insulation in a converter transformer. To study the accumulation and decay characteristics of the space charge within oil-impregnated pressboard under DC and polarity reversal voltage, and consider the possible operating conditions of the converter transformer, the space charge behavior of oil-impregnated pressboard was measured by the pulsed electro-acoustic (PEA) method in the temperature range from −20 °C to 60 °C. The effect of temperature on the accumulation and decay characteristics of space charge is also analyzed. The space charge accumulated within the pressboard at low temperature is mainly homocharge injected by the electrode, while heterocharge formed by ion dissociation counteracts some of the homocharge at high temperature. Thus, the space charge of pressboard first increases, then decreases, with an increase in temperature. However, slow decay of the space charge causes severe distortion of the electric field distribution in the pressboard during voltage polarity reversal.

Rough fractional integral operators on Morrey-Adams spaces

In 1981, Adams introduced another variant of Morrey spaces, and we call it the Morrey–Adams space. In this paper, we investigate the boundedness of rough fractional integral operators on Morrey–Adams spaces under a weaker condition. We compare it with Adams’ results. We then reﬁne the results to vanishing Morrey–Adams spaces in the local sense. We also prove the beyond Adams’ inequality of rough fractional integral operators on local Morrey– Adams spaces for the radial functions.
Effect of Health Education on the Knowledge of Cervical Cancer, Human Papillomavirus and Self-sampling Among Women in a Low- Resource Setting

Cervical cancer is a disease of public health importance affecting many women and contributing to avoidably high levels of cancer morbidity and mortality in Nigeria. In spite of the relative ease of prevention, the incidence is on the increase. A key reason is the lack of awareness and knowledge of the disease. This study aimed to evaluate the effect of health education on awareness and knowledge of cervical cancer (CC), human papillomavirus (HPV) and self-sampling (SS) among women in a rural Nigerian community. The study design was pre-post quasi-experimental, carried out among adult women in Orhuwhorun community in Udu Local Government Area (LGA) of Delta State. Multi-stage sampling technique was used to recruit 230 women from May to June 2021. Data were collected by semi structured, self- or interviewer- administered questionnaire. The intervention consisted of structured health education. Data analysis was done with SPSS v. 25.0. Paired sample T-test was used to compare the mean scores before and after educational intervention. A p-value < 0.05 was considered statistically significant. The intervention raised the level of awareness of cervical cancer, HPV and SS from 18.7%, 14.8% and 0.9% respectively to 100% (p < 0.001). The proportion of women with good knowledge of cervical cancer, HPV and self-sampling rose from 11.7% to 97% (p < 0.001), 7.4% to 93% (p < 0.001) and 0.4% to 100% (p < 0.001) respectively. The mean knowledge scores were also increased (p < 0.001). There was statistically significant difference between the pre and post health education scores concerning the knowledge of cervical cancer (t = 42.989, df = 229, p = 0.001), HPV (t = 51.305, df = 229, p = 0.001) and self-sampling (t = 190.369, df = 229, p = 0.001). The awareness and knowledge of cervical cancer, HPV and SS was low among rural women in Delta State before the health education intervention. It is, therefore, imperative that cervical cancer awareness campaigns among this populace be heightened.
Cyclodextrin Inclusion Complexes with Antibiotics and Antibacterial Agents as Drug-Delivery Systems—A Pharmaceutical Perspective

Cyclodextrins (CDs) are a family of cyclic oligosaccharides, consisting of a macrocyclic ring of glucose subunits linked by α-1,4 glycosidic bonds. The shape of CD molecules is similar to a truncated cone with a hydrophobic inner cavity and a hydrophilic surface, which allows the formation of inclusion complexes with various molecules. This review article summarises over 200 reports published by the end of 2021 that discuss the complexation of CDs with antibiotics and antibacterial agents, including beta-lactams, tetracyclines, quinolones, macrolides, aminoglycosides, glycopeptides, polypeptides, nitroimidazoles, and oxazolidinones. The review focuses on drug-delivery applications such as improving solubility, modifying the drug-release profile, slowing down the degradation of the drug, improving biological membrane permeability, and enhancing antimicrobial activity. In addition to simple drug/CD combinations, ternary systems with additional auxiliary substances have been described, as well as more sophisticated drug-delivery systems including nanosponges, nanofibres, nanoparticles, microparticles, liposomes, hydrogels, and macromolecules. Depending on the desired properties of the drug product, an accelerated or prolonged dissolution profile can be achieved when combining CD with antibiotics or antimicrobial agents.
Strategic supplier selection: the importance of process formality in non-automated supplier selection decisions

Abstract Industry 4.0 mainly focuses on the application of modern technologies (digitalization) and the changing role of human beings (digital transformation) in modern production and logistics systems. Besides the basic principles of digitalization, interconnectivity, and autonomization, the importance of human-centered decision-making processes, such as the selection of strategic suppliers, is also increasing, as complex, novel, and unstructured decisions cannot be fully computerized. In this context, there is still a lack of understanding of which formal patterns in the strategic supplier selection process will lead to better supplier performance. Until now, most of the literature emphasizes a minor number of process-related factors in the strategic supplier selection process leading to limited support for the individual decision-maker. This study introduces a cause-effect model that extends prior research by investigating the impact of process formality, as a comprehensive measurement construct of target-, information-, organization-, and heuristics-related process factors in the strategic supplier selection process on supplier performance and purchaser satisfaction. Based on the usage of variance-based structural equation modeling in a large-scale field study, a significant relationship between process formality and supplier performance as well as between process formality and purchaser satisfaction is substantiated.
Use of a mobile application for the control of anticoagulation with warfarin: a cluster randomized controlled clinical trial - Ijui/RS/Brazil

To evaluate the effectiveness of an anticoagulation protocol adapted in a mobile application (appG) for patients using warfarin. This was a cluster randomized controlled clinical trial carried out in basic health centers of Ijui, RS, Brazil, between April and October 2017. The appG was installed on the cell phones of all physicians belonging to the intervention group. Primary outcomes were bleeding and thrombosis, and secondary outcomes were changes in the dose of warfarin, use of new drugs, drug interactions, search for health services, and remaining on the target international normalized ratio. Thirty-three patients belonging to 11 basic health centers were included in this study. From these, 15 patients were in the intervention group which used the appG, and 18 were in the control group. After 6 months, patients in the appG group had fewer bleeding events (7% versus 50%, p-value=0.028) and a lower weekly dose of warfarin (29.3 ± 9.7 mg versus 41.7 ± 12.5 mg, p-value=0.030) when compared to the control group. The anticoagulation protocol adapted in a mobile app reduced bleeding in patients using warfarin.
Trapped waves on interfacial hydraulic falls over bottom obstacles

: Hydraulic falls on the interface of a two-layer density stratiﬁed ﬂuid ﬂow in the presence of bottom topography are considered. We extend the previous work [1] to two successive bottom obstructions of arbitrary shape. The forced Korteweg-de Vries and modiﬁed Korteweg-de Vries equations are derived in diﬀerent asymptotic limits to understand the existence and classiﬁcation of fall solutions. The full Euler equations are numerically solved by a boundary integral equation method. New solutions characterized by a train of waves trapped between obstacles are found for interfacial ﬂows past two obstacles. Their wavelengths agree well with predictions of the linear dispersion relation. In addition, the eﬀects of the relative location, aspect ratio, and convexity-concavity property of the obstacles on interface proﬁles are investigated.
