Position Control of a Pneumatic Muscle Actuator Using RBF Neural Network Tuned PID Controller

Pneumatic Muscle Actuator (PMA) has a broad application prospect in soft robotics. However, PMA has highly nonlinear and hysteretic properties among force, displacement, and pressure, which lead to difficulty in accurate position control. A phenomenological model is developed to portray the hysteretic behavior of PMA. This phenomenological model consists of linear component and hysteretic component force. The latter component is described by Duhem model. An experimental apparatus is built up and sets of experimental data are acquired. Based on the experimental data, parameters of the model are identified. Validation of the model is performed. Then a novel cascade position PID controller is devised for a 1-DOF manipulator actuated by PMA. The outer loop of the controller is to cope with position control whilst the inner loop deals with pressure dynamics within PMA. To enhance the adaptability of the PID algorithm to the high nonlinearities of the manipulator, PID parameters are tuned online using RBF Neural Network. Experiments are performed and comparison between position response of RBF Neural Network based PID controller and that of classic PID controller demonstrates the effectiveness of the novel adaptive controller on the manipulator.
Inmunonutrición en el paciente oncológico quirúrgico: actualización y estado del arte

La desnutrición en el paciente con cáncer que es sometido a un procedimiento quirúrgico es uno de los problemas nutricionales mayormente asociado con desenlaces clínicos adversos, como aumento en el riesgo de las infecciones, mayor riesgo de formación de fístulas e incremento en los días de estancia hospitalaria y en el riesgo de mortalidad. La inmunonutrición (IMN) se refiere al uso de diversos nutrimentos en dosis mucho más altas de los requerimientos diarios, con la finalidad de lograr una modulación en la respuesta del sistema inmune del huésped en el proceso inflamatorio y una mejoría en el estado de nutrición en pacientes quirúrgicos. Es importante conocer el estado actual del uso de la IMN en el paciente con cáncer sometido a una cirugía, con la finalidad de aplicar correctamente la terapia nutricional y disminuir los desenlaces clínicos adversos, así como aumentar la supervivencia. El objetivo de esta revisión es conocer el estado actual del arte de la IMN en el paciente oncológico quirúrgico para llegar, de forma puntual, a recomendaciones en la práctica clínica basadas en la mejor evidencia científica disponible en la actualidad.
Drop tube generates 10‐W flashes of sonoluminescence

Use of a low vapor pressure liquid such as phosphoric acid, with dissolved xenon in a vertically exited tube, generates ∼200‐ns flashes of sonoluminescence with a peak power of 10 W. We are in the process of characterizing the bubble motion by use of backlighting, stroboscopic, and streak photography. We will also broach the topic of disequilibrium between atom and electron temperatures. [Research funded by DARPA. We thank Carlos Camara and Shahzad Khalid for valuable discussions. ] a)Deceased.
An Extension of Bilinear Hilbert Transform to Distributions

The bilinear Hilbert transform H α: L 2 x L ∞ → L 2 respectively, H α: L P1 x L P2 → L P , is extended to D′ L2 x D L∞ → D′ L2, respectively, D′ Lq x D LP2; → D′ q1, (with suitable parameters) as a hypocontinuous, respectively, continuous mapping. The bilinear Hilbert transform of Schwartz distributions is defined as an irregular operation. The inversion formula is given. It is used as a product formula for appropriate pairs of distributions.
Single-Phase Five-Level Multilevel Inverter Based on a Transistors Six-Pack Module

This article introduces a single-phase five-level multilevel inverter based on six switches and two transformers. The proposed converter requires a single dc input source with low voltage. The disposition of switches makes it possible to build the converter with a transistors six-pack module off-the-shelves, traditionally used to build three-phase inverters, which simplifies the manufacturing process. The converter increases the voltage with two transformers; for that reason, it does not require an auxiliary step-up converter. The use of transformers (with the transformer’s turns ratio) allows for using the same topology for several input voltage levels. To verify the operation of the proposed multilevel inverter, a computer-based simulation was performed with PSIM, a software that considers parasitic components. The results show that the proposed converter can work properly.
Diagnostic Accuracy and Reliability of Noncontrast Computed Tomography Markers for Acute Hematoma Expansion among Radiologists

Background: Noncontrast Computed Tomography (NCCT) features are promising markers for acute hematoma expansion (HE) in patients with intracerebral hemorrhage (ICH). It remains unclear whether accurate identification of these markers is also reliable in raters with different levels of experience. Methods: Patients with acute spontaneous ICH admitted at four tertiary centers in Germany and Italy were retrospectively included from January 2017 to June 2020. In total, nine NCCT markers were rated by one radiology resident, one radiology fellow, and one neuroradiology fellow with different levels experience in ICH imaging. Interrater reliabilities of the resident and radiology fellow were evaluated by calculated Cohen’s kappa (κ) statistics in reference to the neuroradiology fellow who was referred as the gold standard. Gold-standard ratings were evaluated by calculated interrater κ statistics. Global interrater reliabilities were evaluated by calculated Fleiss kappa statistics across all three readers. A comparison of receiver operating characteristics (ROCs) was used to evaluate differences in the diagnostic accuracy for predicting acute hematoma expansion (HE) among the raters. Results: Substantial-to-almost-perfect interrater concordance was found for the resident with interrater Cohen’s kappa from 0.70 (95% CI 0.65–0.81) to 0.96 (95% CI 0.94–0.98). The interrater Cohen’s kappa for the radiology fellow was moderate to almost perfect and ranged from 0.58 (95% CI 0.52–0.65) to 94 (95% CI 92–0.97). The intrarater gold-standard Cohen’s kappa was almost perfect and ranged from 0.79 (95% CI 0.78–0.90) to 0.98 (95% CI 0.78–0.90). The global interrater Fleiss kappa ranged from 0.62 (95%CI 0.57–0.66) to 0.93 (95%CI 0.89–0.97). The diagnostic accuracy for the prediction of acute hematoma expansion (HE) was different for the island sign and fluid sign, with p-values < 0.05. Conclusion: The NCCT markers had a substantial-to-almost-perfect interrater agreement among raters with different levels of experience. Differences in the diagnostic accuracy for the prediction of acute HE were found in two out of nine NCCT markers. The study highlights the promising utility of NCCT markers for acute HE prediction.
Emprendimiento en economías emergentes: una revisión sistemática de literatura

En 2008 se argumentó que los contextos institucionales de las economías emergentes difieren de las economías avanzadas, las cuales configuran la acción emprendedora. En ese sentido, se revisó 60 artículos sobre el emprendimiento en las economías emergentes y se descubrió que en efecto las débiles estructuras institucionales pueden influir en el comportamiento emprendedor, también se encontró que las teorías existentes sobre el emprendimiento dejan vacíos al intentar explicar el fenómeno en países caracterizados por elevados niveles de desigualdad, inseguridad y entornos institucionales llenos de corrupción. Como resultado se ofrecen algunas orientaciones para futuras investigaciones sobre el emprendimiento en los mercados emergentes.
Estimates of Quality-Adjusted Life-Year Loss for Injuries in the United States

Purpose The goal of this study is to develop an approach for estimating nationally representative quality-adjusted life-year (QALY) loss from injury and poisoning conditions using data collected in the Medical Expenditure Panel Survey (MEPS) and the National Health Interview Survey (NHIS). Methods This study uses data from the 2002–2015 NHIS and MEPS surveys. Injuries were identified in the MEPS medical events file and through self-reporting of medical conditions. We restricted our model to 163,731 adults, for which we predict a total of 294,977 EQ-5D scores using responses to the self-administered questionnaire. EQ-5D scores were modeled using age, sex, comorbidities, and binary indicators of the presence and duration of injury at the time of the health status questionnaire. These models consider nonlinearity over time during the first 3 y following the injury event. Results Injuries are identified in MEPS using medical events that provide a reasonable proxy for the date of injury occurrence. Health-related quality of life (HRQL) decrements can be estimated using binary indicators of injury during different time periods. When grouped into 29 injury categories, most categories were statistically significant predictors of HRQL scores in the first year after injury. For these groups of injuries, mean first-year QALY loss estimates range from 0.005 (sprains and strains of joints and adjacent muscles, n = 7067) to 0.109 (injury to nerves and spinal cord, n = 71). Fewer estimates are significant in the second and third years after injury, which may reflect a return to baseline HRQL. Conclusion This research presents both a framework for estimating QALY loss for short-lived medical conditions and nationally representative, community-based HRQL scores associated with a wide variety of injury and poisoning conditions. Highlights This research provides a catalog of nationally representative, preference-based EQ-5D score decrements associated with surviving a large set of injuries, based on patient-reported health status. Mean first-year QALY loss estimates range from 0.005 (sprains and strains of joints and adjacent muscles, n = 7067) to 0.109 (injury to nerves and spinal cord, n = 71). This article presents a novel methodology for assessing quality-of-life impacts for acute conditions by calculating the time elapsed between injury and health status elicitation. Researchers may explore adapting these methods to study other short-lived conditions and health states, such as COVID-19 or chemotherapy.
Plant-Programmed Cell Death-Associated Genes Participation in Pinus sylvestris L. Trunk Tissue Formation

Molecular genetic markers of various PCD (programmed cell death) variants during xylo- and phloemogenesis have been identified for the first time in Scots pine under lingonberry pine forest conditions in Northwest Russia (middle taiga subzone). PCD is a genetically determined process. Gene profiles of serine and cysteine proteases (endopeptidases), endonucleases, and metacaspases families are often considered markers of the final xylogenesis stage. In the present study, we examined the gene expression profiles of the BFN (bifunctional endonuclease) family—BFN, BFN1, BFN2, BFN3, and peptidase (cysteine endopeptidase, CEP and metacaspase, MC5) in the radial row, in addition to the vascular phloem and cambium (F1), differentiating xylem (F2), sapwood (SW), and transition zone during the active cambial growth period of uneven-aged pine trees (25-, 63- and 164-cambial age (c.a.) years old). We have shown that the expression patterns of the PCD-related genes did not depend on the cambial age but were largely determined by plant tissue type. In the radial row F1-F2-SW, we studied the activities of enzymes, including sucrose in metabolism (sucrose synthase, three forms of invertase); antioxidant system (AOS) enzymes (superoxide dismutase, catalase); and peroxidase andpolyphenol oxidase, which belonged to AOS enzymes and were involved in the synthesis of phenolic components of cell walls. The activity of the enzymes indicated that the trunk tissues of pine trees had varying metabolic status. Molecular genetic PCD regulation mechanisms during xylem vascular and mechanical element formation and parenchyma cells’ PCD during the formation of Scots pine heartwood were discussed.
HPV-positive cervical squamous cell carcinoma metastasis to the breast, mimicking primary tumor

INTRODUCTION: Metastatic disease to the breast is a rare condition, with contralateral breast metastasis being the most common primary site. CASE PRESENTATION: We present the case of a patient who underwent treatment for an HPV positive squamous cell carcinoma (SCC) of the cervix who, during follow-up, complained of a nodule in her left breast. Anatomopathological results indicating squamous carcinoma, which was not able to be differentiated from breast metaplastic carcinoma. Resection of the lesion was carried out, confirming carcinoma with squamous cell differentiation with negativity for GCDFP-15, mammaglobin, p63 and SOX10, but with positivity for p16 and for high risk HPV, confirming a single metastatic lesion of cervical carcinoma. DISCUSSION/CONCLUSION: In the presence of SCC in the breast, the differential diagnosis may consider the presence of primary lesion, metaplastic carcinoma with squamous cell differentiation or metastatic disease. The use of markers such as p63, SOX10 and p16, may help for a definitive diagnosis.
Topic optimization–incorporated collaborative recommendation for social tagging

PurposeWith the continuous increase of users, resources and tags, social tagging systems gradually present the characteristics of “big data” such as large number, fast growth, complexity and unreliable quality, which greatly increases the complexity of recommendation. The contradiction between the efficiency and effectiveness of recommendation service in social tagging is increasingly becoming prominent. The purpose of this study is to incorporate topic optimization into collaborative filtering to enhance both the effectiveness and the efficiency of personalized recommendations for social tagging.Design/methodology/approachCombining the idea of optimization before service, this paper presents an approach that incorporates topic optimization into collaborative recommendations for social tagging. In the proposed approach, the recommendation process is divided into two phases of offline topic optimization and online recommendation service to achieve high-quality and efficient personalized recommendation services. In the offline phase, the tags' topic model is constructed and then used to optimize the latent preference of users and the latent affiliation of resources on topics.FindingsExperimental evaluation shows that the proposed approach improves both precision and recall of recommendations, as well as enhances the efficiency of online recommendations compared with the three baseline approaches. The proposed topic optimization–incorporated collaborative recommendation approach can achieve the improvement of both effectiveness and efficiency for the recommendation in social tagging.Originality/valueWith the support of the proposed approach, personalized recommendation in social tagging with high quality and efficiency can be achieved.
The upgraded HADES trigger and data acquisition system

The HADES experiment is a High Acceptance Di-Electron Spectrometer located at GSI in Darmstadt, Germany. Recently, its trigger and data acquisition system was upgraded. The main goal was to substantially increase the event rate capability by a factor of up to 20 to reach 100 kHz in light and 20 kHz in heavy ion reaction systems. The total data rate written to storage is about 400 MByte/s in peak.In this context, the complete read-out system was exchanged to FPGA-based platforms using optical communication. For data transport a general-purpose real-time network protocol was developed to meet the strong requirements of the system. In particular, trigger information has to reach all front-end modules with latencies of less than 5 μs through up to 10 intermediate hubs in a star-like network setup. Monitoring and slow control features as well as readout and trigger distribution were joined in a single network protocol made up by three virtual channels with inherent arbitration by priority and a typical switching time of 100 ns. The full DAQ system includes about 550 FPGAs distributed over the complete detector system. For control and monitoring a virtual address space spanning the whole network is provided. Data are merged by the network hubs into data streams and passed on to a server farm using an Ethernet infrastructure. Due to the electromagnetic noise environment, several transmission error detection and correction features were included.In collaboration with groups from experiments of the FAIR accelerator complex, further developments based on the versatile hardware and communication protocol are being pursued.
How Can the Sustainable Motivational Effect of Equity Incentives on Corporate Performance Be Exploited?—A Study Based on the Moderating Effect of Aspiration Level

How equity incentives affect corporate performance has become a consensus. However, the question of how to maximize the sustainable incentive effect of equity incentives on corporate performance and avoid “short-sighted” behavior under equity incentives has not yet been resolved. This research re-examines the sustainable incentive of equity incentives and examines the moderating role of aspiration levels based on the behavioral theory of the firm and the prospect theory. Applying panel data comprised 9588 observations from Chinese A-share listed companies spanning the period from 2011 to 2019, this study found that there is an inverted U-shaped relationship between equity incentives and corporate performance. Aspiration surplus negatively moderates the curvilinear inverted U-shaped relationship. As the level of aspiration surplus changes from low to high, the curvilinear relationship between equity incentives and corporate performance is weakened. Aspiration loss positively moderates the curvilinear inverted U-shaped relationship. As the level of aspiration loss changes from low to high, the curvilinear relationship between equity incentives and corporate performance is enhanced. This study demonstrates the importance of aspiration level between equity incentives and corporate performance, guiding firms to focus on the implementation scenario as an influencing factor in order to improve the sustainable incentive effect of equity incentives.
Mass flows, turbidity currents and other hydrodynamic consequences of small and moderate earthquakes in the Sea of Marmara

Abstract. Earthquake-induced submarine slope destabilization is known to cause mass wasting and turbidity currents, but the hydrodynamic processes associated with these events remain poorly understood. Instrumental records are rare, and this notably limits our ability to interpret marine paleoseismological sedimentary records. An instrumented frame comprising a pressure recorder and a Doppler recording current meter deployed at the seafloor in the Sea of Marmara Central Basin recorded the consequences of a Mw 5.8 earthquake occurring on 26 September 2019 and of a Mw 4.7 foreshock 2 d before. The smaller event caused sediment resuspension and weak current (<4 cm s−1) in the water column. The larger event triggered a complex response involving a debris flow and turbidity currents with variable velocities and orientations, which may have resulted from multiple slope failures. A long delay of 10 h is observed between the earthquake and the passing of the strongest turbidity current. The distance traveled by the sediment particles during the event is estimated to have extended over several kilometers, which could account for a local deposit on a sediment fan at the outlet of a canyon (where the instrument was located), but the sedimentation event did not likely cover the whole basin floor. We show that after a moderate earthquake, delayed turbidity current initiation may occur, possibly by ignition of a cloud of resuspended sediment.
Enumeration of monochromatic three term arithmetic progressions in two-colorings of cyclic groups

One of the toughest problems in Ramsey theory is to determine the existence of monochromatic arithmetic progressions in groups whose elements have been colored. We study the harder problem to not only determine the existence of monochromatic arithmetic progressions, but to also count them. We reformulate the enumeration in real algebraic geometry and then use state of the art computational methods in semidefinite programming and representation theory to derive sharp, or an explicit constant from sharp, lower bounds for the cyclic group of any order.
Q-learning algorithm using an adaptive-sized Q-table

Q-learning is one of the successfully established algorithms for the reinforcement learning. It directly estimates optimal Q-values for pairs of states and admissible actions. By using these Q-values, agents can obtain the optimal movement in controlled Markovian domains without using an explicit model of the desired system. However, the algorithm requires a large number of actions of trial and error in the early stages of learning. In this paper, a Q-learning algorithm using the Memory Based Learning (MBL) system is proposed. By using the generalization property of the MBL system, the learning effect for a Q-value can be spread to adjacent Q-values, and thus the number of actions of trial and error can be reduced. Finally, computer simulation results for the control of inverted pendulums are presented to show the effectiveness of the proposed method.
Effect of Mahogany (Swietenia mahagoni Jacq.) Extract on the Islet Cells’ Number and Blood Glucose Levels of Alloxan-induced Diabetic Rat

Effect of Mahogany (Swietenia mahagoni Jacq.) Extract on the Islet Cells’ Number and Blood Glucose Levels of Alloxan-Induced Diabetic Rat. This study was to know the effect of ethanol extract of mahogany (S. mahagoni Jacq.) seeds on the number of islet cells in the pancreatic Langerhans and blood glucose levels of alloxan-induced diabetic white rat (Rattus norvegicus). Twenty-five male rats were divided into five groups consists of: (C-) 1-mL/day aquadest without alloxan induction, (C+) 120 mg/kgBW alloxan and 1-mL/day aquadest, (T1, T2, T3) 120 mg/kgBW alloxan and 250, 500, 1000 mg/kgBW of ethanol extract of mahogany seeds respectively. Alloxan were injected intraperitoneal with single dose and ethanol extract of mahogany seeds administered via intragastric gavage for 14 days. At the end of the treatment period, the number of islet cells in the pancreatic Langerhans was counted and blood glucose levels were measured. This research showed that the ethanol extract of mahogany seeds have antidiabetic effect that can repair damaged islet cells in the pancreatic Langerhans at effective dose of 500 mg/kgBW with a mean number of 151.83 ± 11.07 that significantly higher (p less than 0.05) than treatment group 1 (T1), treatment group 3 (T3) and positive control group (C+) and also decreased the blood glucose levels from > 200 mg/dL to normal range (50–135 mg/dL). This is due to the antioxidant property of mahogany seeds extract which is beneficial in repairing pancreas damage due to oxidative stress.
