Small extracellular vesicles (exosomes) are important components of the tumor microenvironment. They are small membrane-bound vesicles derived from almost all cell types and play an important role in intercellular communication. Exosomes transmit biological molecules obtained from parent cells, such as proteins, lipids, and nucleic acids, and are involved in cancer development. MicroRNAs (miRNAs), the most abundant contents in exosomes, are selectively packaged into exosomes to carry out their biological functions. Recent studies have revealed that exosome-delivered miRNAs play crucial roles in the tumorigenesis, progression, and drug resistance of hepatocellular carcinoma (HCC). In addition, exosomes have great industrial prospects in the diagnosis, treatment, and prognosis of patients with HCC. This review summarized the composition and function of exosomal miRNAs of different cell origins in HCC and highlighted the association between exosomal miRNAs from stromal cells and immune cells in the tumor microenvironment and the progression of HCC. Finally, we described the potential applicability of exosomal miRNAs derived from mesenchymal stem cells in the treatment of HCC.

COCKPIT CREW SAFETY PERFORMANCE PREDICTION BASED ON THE INTEGRATED MACHINE LEARNING MULTI-CLASS CLASSIFICATION MODELS AND MARKOV CHAIN
Authors: Borjalilu Naimeh , Jolai Fariborz , Tavakoli Mahdieh
Published: October 2023

The main tool of cockpit crew performance evaluation is the recorded flight data used for flight operations safety improvement since all certified airlines require implementation of a safety and quality management system. The safety performance of a flight has been a challenging issue in the aviation industry and plays an important role to acquire competitive benefits. In this study, an integrated multi-class classification machine learning models and Markov chain were developed for cockpit crew performance evaluation during their flights. At the outset, the main features related to a flight are identified based on the literature review, flight operations expert’s statements, and the case study dataset (as numerical example). Afterwards, the flights’ performance is evaluated as a target column based on four multi-class classification models (Decision Tree, Support Vector Machine, Neural Network, and Random Forest). The results showed that the random forest classifier has the greatest value in all evaluation metrics (i.e., accuracy = 0.90, precision = 0.91, recall = 0.97, and F1-score = 0.93). Therefore, this model can be used by the airline companies to predict flight crew performance before the flight in order to prevent or decrease flight safety risks.

Authors: Sajadian Sedighe , Mahmoudzadeh Arya , Moein Setareh
Published: October 2023

Gravitational microlensing is a powerful method for discovering isolated stellar-mass black holes (ISMBHs). These objects make long-duration microlensing events. To characterize these lensing objects by fully resolving the microlensing degeneracy, measurements of parallax and astrometric deflections are necessary. Microlensing events due to ISMBHs have considerable astrometric deflections but small parallax amplitudes,

, where M
l is the lens mass. We numerically investigate the possibility of inferring parallax amplitude from astrometric deflection in microlensing events due to ISMBHs. The parallax amplitude in astrometric deflections is proportional to the relative parallax π
rel, which means that it (i) does not strongly depend on M
l and (ii) increases in microlensing observations toward the Magellanic Clouds. We assume that these events will be potentially detected in upcoming microlensing surveys such as (1) the Roman observations of the Galactic bulge (GB) and (2) the LSST observations of the Large Magellanic Cloud (LMC) and that the Extremely Large Telescope (ELT) will follow up on them with one data point every 10 days. We evaluate the probability of inferring parallax amplitude from these observations by calculating the Fisher and covariance matrices. For the GB, the efficiencies for discerning parallax amplitudes with a relative error of <4% through astrometric and photometric observations are 3.8% and 29.1%, respectively. For observations toward the LMC, these efficiencies are 41.1% and 23.0%, respectively. Measuring parallax amplitude through astrometric deflections is plausible in GB events with a lens distance of ≲2.7 kpc and in LMC halo lensing. By monitoring long-duration microlensing events, the ELT can detect astrometric deflections and their parallax-induced deviations.

Published: October 2023

Abstract: In the complex treatment of chronic heart failure (CHF) β-adrenoblockers (carvedilol, nebivolol, bisoprolol, metoprolol) are used, which due to their pharmacological properties increase the survival rate of patients, improve cardio- and haemodynamic parameters, metabolism. However, modern realities in medicine require creation of new more effective and safe β-adrenoblockers. In this regard, the potential drug Hypertirl is of interest. The aim was to evaluate the cardioprotective effect of 1-(b-phenylethyl)-4-amino-1,2,4-triazolium bromide (Hypertril) on cardiac electrical activity and autonomic regulation of heart rhythm in a model of CHF in comparison with β-adrenoblockers of different generations (Nebivolol, Carvedilol, Bisoprolol, Metoprolol).

Materials and methods: Chronic heart failure was induced by 14-day administration of doxorubicin in a cumulative dose of 15 mg/kg to white mongrel rats weighing 190–220g (total 85). The investigated drugs were administered after doxorubicin course for 30 days: Hypertril at an experimentally substantiated dose of 3.5 mg/kg, Metoprolol succinate 15 mg/kg, Nebivolol 10 mg/kg, Carvedilol 50 mg/kg, Bisoprolol 10 mg/kg. At the end of drug administration under thiopental anaesthesia (40 mg/kg), electrocardiogram (ECG) and autonomic regulation of heart rhythm (ARHR) were analysed using a computer analyser CardioCom-2000plus (KAI-Medica, Ukraine). The results of the study were calculated using a standard statistical package “STATISTICA for Windows 6.0” (StatSoftInc., №AXXR712D833214FAN5), “SPSS 16.0” and “Microsoft Office Excell 2003”.

Results and discussion: Hypertril administration resulted in a negative chronotropic effect, normalisation of atrial (P) and ventricular (R) spike amplitude, ST segment inversion below isoline, increased amplitude of ventricular myocardial repolarisation T. Myocardial repolarisation spike were observed, as well as normalised the duration of atrial (P) and ventricular depolarisation phase (QRS complex) to the intact value and restored the duration of electrical diastole (TR interval). Hypertril reduced systolic and diastolic myocardial dysfunction in animals with CHF. Hypertril restored autonomic mechanisms of heart rhythm regulation and balanced activity of sympathetic and parasympathetic parts of autonomic nervous system in the control of cardiac function.

Conclusion: The obtained results demonstrated the undoubted advantage of the new original molecule (Hypertril) over basic β-adrenoblockers (Metoprolol, Nebivolol, Carvedilol and Bisoprolol) and experimentally justify further in-depth study to create on its basis a drug for the treatment of CHF.

Authors: Abualruz Hasan , Hayajneh Ferial
Published: October 2023

Background:

The stress level among nurses is significantly high, which negatively affects the nurses' well-being and the quality of care provided to patients. The goal of this study was to measure the impact of implementing a resiliency training program on nurses.

Method:

A pretest-posttest quasi-experimental design was used to measure the impact of nurses' participation in a resiliency training program. The sample was recruited with the convenience sampling technique. Participants were allocated to groups according to their ability to attend all intervention sessions. A total of 137 participants completed all phases of the study. The study was conducted at a private hospital in Amman, Jordan. Data were collected at two time points, before the intervention and 1 week after the intervention.

Results:

Analysis of covariance was used to measure differences between groups after the intervention. The results indicated that there were statistically significant differences (
p
< .001) in resilience and stress levels between the groups after the intervention.

Conclusion:

Nurses in the intervention group showed a significant improvement in resilience scores and a significant reduction in stress scores.

Adaptive learning nonsynchronous control of nonlinear hidden Markov jump systems with limited mode information
Authors: Ma Chao , Gao Hang , Wu Wei
Published: October 2023

In this paper, an adaptive neural network learning based nonsynchronous control method is developed for hidden Markov jump systems with unmodeled nonlinear dynamics. In particular, the system modes are not directly accessible and the limited mode information can be partly estimated by the nonsynchronous controller. More precisely, the mode information with partly accessible transition rates is utilized based on the transition probability matrix. Moreover, the unmodeled nonlinear dynamics are more general in practical applications. Based on the designed mode-dependent controllers with mode observation, sufficient conditions are first exploited by means of the Lyapunov method, such that the desired control performance could be ensured in the mean-square sense. Then, the nonsynchronous mode-dependent controllers are further determined in terms of convex optimization. In the end, our proposed control strategy is applied to a robotic manipulator with varying loads to validate the feasibility with simulation results.
Ecological and Floristic Plant Surveys of Little Wabash River Nature Preserve, Indiana

Published: October 2023

Forests in northeastern Indiana are relegated to relatively small fragments and have become important patches in a landscape dominated by agriculture. Little Wabash River Nature Preserve is a property in Allen County, Indiana, closed to the public and protected by ACRES Land Trust. We conducted ecological surveys at 48 regular plots located along seven transects through the property that consisted of identifying and counting individual plants at understory, midstory, and overstory strata and recording several ecological factors. These were augmented by floristic meandering surveys during the growing season of 2019 to record plant species that may not have been encountered at the ecological plots and thereby give a fuller picture of the floristic composition of the property. We encountered a total of 251 identified species during the ecological and floristic surveys. Analysis showed understory abundance, richness, and diversity were positively related to available light (photosynthetically active radiation) and negatively related to canopy cover. The most abundant species in the midstory were non-native species. Juglans nigra had the greatest frequency and dominance in the overstory. In nonmetric multidimensional scaling, there was clear separation of the plant community within the forested portion from the community in the adjacent to the small old-field. Mean C-value for the site was 2.87, which resulted in a 41.56 FQI. The FQI may be an over-estimation of the conservation importance of the site and the Mean C-value may be an under-estimation of that importance. Overall, the Nature Preserve provides an example of the plant diversity can exist in a small, protected forest. While there are some common non-native species, there is habitat for a relatively large pool of species and may be of importance for protection within the surrounding disturbed landscape.

Published: October 2023

The study of water condensation phenomena is important in order to evaluate the performance of materials and coatings employed in the fabrication of waste heat recovery units including heat exchangers, heat pipes, condensing economizers and related functional surfaces. Fast evaluation of lab-scale samples is important during research and development of coatings for wetting phenomena under controlled, reproducible, and stable humidity and temperature conditions of both sample and environment. To study these effects, we report on the construction of a lab-scale condensation chamber, along with its evaluation and benchmarking with superhydrophobic coatings on stainless steel using perfluorooctyl silane (PFOTS). A working unit has been successfully fabricated and applied in a highly responsive device capable of recording the condensation performance of flat specimens under controlled conditions. Sample temperature was maintained with 0.10 °C deviation. The humidity response time of the chamber is 17.2 s per degree of RH% while the maximum relative humidity variation is +/- 3.2%RH. The unit successfully delivered valuable data over hydrophillic, hydrophobic and superhydrophobic surfaces. Data useful for studying open research issues such the relationship of contact angle and condensation phenomena.

Published: October 2023

Cholangiocytes, the epithelial cells that line the biliary tree, can proliferate under the stimulation of several factors through both autocrine and paracrine pathways. The cocaine-amphetamine-regulated-transcript (CART) peptide has several physiological functions, and it is widely expressed in several organs. CART increases the survival of hippocampal neurons by upregulating brain-derived neurotrophic factor (BDNF), whose expression has been correlated to the proliferation rate of cholangiocytes. In the present study, we aimed to evaluate the expression of CART and its role in modulating cholangiocyte proliferation in healthy and bile duct ligated (BDL) rats in vivo, as well as in cultured normal rat cholangiocytes (NRC) in vitro. Liver samples from both healthy and BDL (1 week) rats, were analyzed by immunohistochemistry and immunofluorescence for CART, CK19, TrkB and p75NTR BDNF receptors. PCNA staining was used to evaluate the proliferation of the cholangiocytes, whereas TUNEL assay was used to evaluate biliary apoptosis. NRC treated or not with CART were used to confirm the role of CART on cholangiocytes proliferation and the secretion of BDNF. Cholangiocytes proliferation, apoptosis, CART and TrkB expression were increased in BDL rats, compared to control rats. We found a higher expression of TrkB and p75NTR, which could be correlated with the proliferation rate of biliary tree during BDL. The in vitro study demonstrated increased BDNF secretion by NRC after treatment with CART compared with control cells. As previously reported, proliferating cholangiocytes acquire a neuroendocrine phenotype, modulated by several factors, including neurotrophins. Accordingly, CART may play a key role in the remodeling of biliary epithelium during cholestasis by modulating the secretion of BDNF.

Active Vibration Control of Electric Drive System in Electric
Vehicles Based on Active Disturbance Rejection Current Compensation under Impact
Conditions
Authors: Ge Shuaishuai , Hou Shuang , Yang Yufan , Zhang Zhigang , Tang Fang
Published: October 2023

To address the torsional vibration caused by impact conditions in electric
vehicles (EVs), such as deceleration belts and road irregularities, a
comprehensive electromechanical coupling dynamics model is developed. This model
includes the dynamic behavior of the permanent magnet synchronous motor (PMSM)
and the gear transmission system in the EV’s electric drive system. The study
aims to investigate the electromechanical coupling dynamics and vibration
characteristics of the system under impact conditions. Based on this, an
innovative active damping control strategy is proposed for the EV’s electric
drive system when subjected to impact conditions. This strategy incorporates
active disturbance rejection current compensation (ADRCC) to achieve a speed
difference of zero at two ends of the half-shaft as the tracking control target,
and compensating current is superimposed on the original given current of the
motor controller. The results highlight the effectiveness of the proposed
strategy. Under single-pulse impact condition, the vibration energy of the gear
transmission system is reduced by approximately 63.1% compared to without the
controller. Under continuous impact conditions, the vibration energy of the gear
transmission system is reduced by approximately 55.63% and the cumulative error
of the speed difference is reduced by approximately 61.4% compared to without
the controller. These findings demonstrate that the proposed strategy
successfully suppresses the continuous oscillation of the electric drive system
under impact conditions. The research results provide a theoretical reference
for the vibration suppression of the electric drive system of EVs.

This research investigates the patterns of representation in Joko Widodo’s corpus of presidential speech. The research method used is a mixed method that combines quantitative and qualitative analysis. The data of the research are transcriptions of President Joko Widodo’s speech text in 2015 and in 2018. In order to be processed with a corpus analysis tool, the data is stored in a text file or .txt format with UTF-8 encoding. The instrument which is used in this study is AntConc. It also brings up words that often appear and keywords in the corpus and analyzes text patterns with certain letter arrangements. Regarding patterns in the text, several appear from words contained in the corpus. Among them are the existence of words that have prefixes, suffixes, prefixes and suffixes, and repetition. Further, from the frequency and keyword analysis, it can be seen that Joko Widodo is focusing his attention on achieving the goals for the Indonesian nation and state, both in the 2015 and 2018 speech texts. It can be concluded, therefore, that Widodo is consistent in his speech patterns. On the other hand, this may be considered a new breakthrough because the speech from 2018 uses the same speech patterns as the speech from three years earlier.

Language preference is an activity to select a default language for language users. In several activities, we, as language users often found that speakers tend to choose certain language to be used in communication. The objective of this reasearch is is to investigate the preference of language used by Information Technology (IT) students in Budi Darma University Medan in year 2022, which language they prefer to use, Bahasa Indonesia or English? Especially when they learn and discuss about computer or informatioan and techology matter in the classroom or computer laboratory. The participants of this research are fifty (50) EFL learners in Budi Darma who are the native speakers of Indonesian Language which is called Bahasa Indonesia. The researchers would like to find out which language is preferable to be used in the classroom especially when they talk about technology (IT) related to the computer. Piper (1986) popular with “labspeak” term, is there any relation to use certain language rather than other language when the students in computer laboratory? The investigation is done to found out their reasons why they prefer using certain language when they talk about computer and technology (IT) in the classroom. To find the answer, the reasearchers observe and interview the students, the preferable language used by the EFL learners and also reasons of those EFL learners become the finding of this research. The motivations of those students using certain language rather than other language when they talk bout Technology or Information Technology related to computer is also considered esential to support the finding of this research).

Real-time hand gesture detection is an interesting topic in pattern recognition and computer vision. In this study, we propose the use of a Convolutional Neural Network (CNN) to detect and recognize hands in real-time. Our goal is to develop a system that can accurately identify and interpret user gestures in real-time. The proposed approach involves two main stages, namely hand gesture recognition and gesture recognition. For stage detection, we use the CNN architecture to recognize hands in the video. We train the CNN model using a dataset containing various hand gestures. Once a hand is detected, we extract the relevant hand region and proceed to the gesture recognition stage. The gesture recognition stage involves training and testing CNN models for different hand signal recognition. We use a hand gesture dataset that contains a variety of common hand signals. The experimental results show that the proposed system can detect and recognize hand movements in real-time with satisfactory accuracy. Although there are still some challenges that need to be overcome, this research provides a solid foundation for further development in real-time hand gesture recognition.
