Use of Gaussian Process to Model, predict and Explain Human Emotional response to Chinese Traditional Music

Music listening is one of the most enigmatic of human mental phenomena; it not only triggers emotions but also changes our behavior. During the music session many people are observed to exhibit varying emotional response, which can be influenced by diverse factors such as music genre and instrument as well as the personal attributes of audiences. In this study, we assume that there is an intrinsic, complex and implicit relationship between the basic sound features of music and human emotional response to the music. The response levels of 12 individuals to a representative repertoire of 36 classical/popular Chinese traditional music (CTM) are systematically analyzed using the chills as a quantitative indicator, totally resulting in 432 ([Formula: see text]) CTM–individual pairs that define a systematic individual-to-music response profile (SPTMRP). Gaussian process (GP) is then employed to model the multivariate correlation of SPTMRP profile with 15 sound features (including 5 Timbres, 4 Rhythms and 6 Pitchs) and 5 individual features in a supervised manner, which is also improved by genetic algorithm (GA) feature selection and compared with other machine learning methods. It is shown that the built GP regression model possesses a strong internal fitting ability ([Formula: see text]) and a good external predictive power ([Formula: see text]), which performed much better than linear PLS and nonlinear SVM and RF, confirming that the human emotional response to music can be quantitatively explained by GP methodology. Statistical examination of the GP model reveals that the sound features contribute more significantly to emotional response than individual features; their importance increases in the order: [Formula: see text], in which the spectral centroid (SC), relative amplitude of salient peaks (RASP), ratio of peak amplitudes (RPA), sum of all rhythm histograms (SARH) and period of unfolded maximum peak (PUMP) as well as gender are primarily responsible for the response.
Direct dissolution of metal oxides in ionic liquids as a smart strategy for separations: Current status and prospective

ABSTRACT The dissolution of metal oxide in ionic liquid (IL) medium is an important and challenging issue for the development of alternative solvent systems for carrying out non-aqueous chemistry operations of metal ions in the nuclear field where IL could be a potential alternative to the high-temperature molten salt for non-aqueous processing of metal ions. This review article emphasizes on the developments in the field of dissolution of metal oxides in IL medium particularly that of the of oxides of uranium and few other metal oxides including those of lanathanides which have relevance in the spent nuclear fuel (SNF) reprocessing. The dissolution of metal oxides in ILs is broadly divided on the basis of different factors affecting the dissolution. The chloroaluminate-based ILs although reported to have dissolved many oxides including inert oxides suffer from the air and moisture sensitivity issues whereas the dissolution of metal oxides in acid and water stable ILs are limited by the solubility of acid and water in the ILs. Task-specific ionic liquids (TSIL) containing Brønsted acid functional groups are reported to have dissolved many oxides depending on the pKa of the functional acid group and the complexing ability of the conjugate base. This review article will help the readers to understand the basic problem of dissolution of metal oxides in ILs and recent development in the field of dissolution.
Polymeric Hydrogels for Controlled Drug Delivery to Treat Arthritis

Rheumatoid arthritis (RA) and osteoarthritis (OA) are disabling musculoskeletal disorders that affect joints and cartilage and may lead to bone degeneration. Conventional delivery of anti-arthritic agents is limited due to short intra-articular half-life and toxicities. Innovations in polymer chemistry have led to advancements in hydrogel technology, offering a versatile drug delivery platform exhibiting tissue-like properties with tunable drug loading and high residence time properties This review discusses the advantages and drawbacks of polymeric materials along with their modifications as well as their applications for fabricating hydrogels loaded with therapeutic agents (small molecule drugs, immunotherapeutic agents, and cells). Emphasis is given to the biological potentialities of hydrogel hybrid systems/micro-and nanotechnology-integrated hydrogels as promising tools. Applications for facile tuning of therapeutic drug loading, maintaining long-term release, and consequently improving therapeutic outcome and patient compliance in arthritis are detailed. This review also suggests the advantages, challenges, and future perspectives of hydrogels loaded with anti-arthritic agents with high therapeutic potential that may alter the landscape of currently available arthritis treatment modalities.
Enhancements of SVM Speaker Recognition by Dynamic Time Wrapping

This paper proposes an approach using dynamic time wrapping (DTW) to improve the classification performance of the SVM separation hyperplane. The presented method by incorporating the distance information derived from DTW template matching calculations into SVM separation hyperplane training will be able to effectively control the balance between mar-gin maximization and the amount of misclassifications, and therefore the recognition accuracy of the SVM classifier on speaker recognition will further be increased. Experimental results demonstrated the effectiveness and efficiency of the developed approach.
Heavy metal mobility, bioavailability, and potential toxicity in sediments of the Korle lagoon in Ghana

ABSTRACT This study aimed to identify the mobility, bioavailability, and potential toxicity of heavy metals (HM) in sediments of the Korle lagoon using metal partition. Sediments were analysed using the BCR (Bureau of reference) method. As (60%), Pb (50%), Zn (57%) and Fe (40%) were found in high concentration in the ion exchangeable fraction. The oxidisable fraction was dominated by Cu (51%), Cd (95%), Cr (61%), Ni (63%), As (35%), Fe (21%), Hg (30%), Pb (19%) and Zn (11%). The reducible fraction was dominated by Zn (29%), Pb (24%) and Hg (19%). The residual fraction was dominated by Hg (49%) and Fe (34%). PCA was used to identify pH and organic matter as the most important factors controlling the mobility and bioavailability of HM in the sediments. Arsenic, Pb, Zn and Fe were found to have the highest mobility. Chromium, Cu and Ni have medium mobility. Hg has low mobility. Most of the HM show potential bioavailability and toxicity.
Characterization of Carbapenem-Resistant Enterobacteriaceae from Patients Stool in Tertiary Hospitals, Port Harcourt, Rivers State, Nigeria

Carbapenem-resistant Enterobacteriacaeae (CRE) are a serious new public-health problem. Carbapenem medicines are a class of antibiotics that are often used to treat severe infections caused by bacteria that are antibiotic-resistant. The goal of this study was to use both conventional and molecular methods to isolate, characterize, and identify Carbapenem-resistant Enterobacteriaceae from stool samples of patients at two tertiary hospitals in Port Harcourt, Rivers State, Nigeria. A total of 114 feacal samples were collected and inoculated onto Eosin methylene blue (EMB) agar and MacConkey agar (M.A) plates. The plates were incubated for 24-48 hours. Representative colonies after incubation were isolated and subjected to phenotypic characterisation using Biochemical Test, followed by antibiotic susceptibility testing. Further characterisation was done by subjecting the isolates to molecular analysis. In this study, 52 isolates of 114 stool samples of enteric organisms were identified; 32 were from females while 20 were from males. The gender distribution of these isolates showed that the Enteric organisms were more predominant in females than in males with male subjects having E. coli 7 (35.0%), Klebsiella spp 7 (35.0%), Salmonella spp 2 (10%), Shigella spp 2 (10%) and Pseudomonas spp 2 (10%) while the female subjects had E. coli 12 (37.5%), Klebsiella spp 13 (40.6%), Salmonella spp 3 (9.4%), Shigella spp 3 (9.4%) and Pseudomonas spp 1 (3.1%). Results showed that Klebsiella spp recorded the highest frequency with 20 (38.5%), followed by E. coli with 19 (36.5%), Salmonella spp 5 (9.6%), Shigella spp 5(9.6%) and Pseudomonas spp 3 (5.8%). Results of the antibiotic susceptibility pattern showed that all the isolates were very susceptible to ciprofloxacin and ofloxacin. Although the meropenem antibiotics showed high sensitivity to the enteric organisms, ciprofloxacin and ofloxacin are recommended for treatment since they have higher antibiotic activities against the enteric bacteria.
Microstructural Variation of Clay during Land Subsidence and the Correlation between Macroscopic and Microscopic Parameters

The nonlinear deformation, visco-elasto-plasticity and other macroscopic properties of soil are the concentrated manifestations of its microstructural state. In order to study the microstructural characteristics and variations of the clay under the action of additional stress caused by groundwater exploitation, borehole sampling was carried out on the clay layers at different depths in a typical land subsidence area. Consolidation tests, freeze-drying, ion sputtering, and scanning electron microscope (SEM) were conducted in order to scan and analyze the microstructure of the test samples at different scales. The Particles and Cracks Analysis System (PCAS) was used to quantify the microscopic parameters, the variations of the microstructural parameters with consolidation loads at different sizes were revealed, and the correlation between the macroscopic and microscopic parameters were discussed. The results show that: (1) the microstructural characteristics of soils with different buried depths have directivity, to a certain extent; (2) as the consolidation load increases, the average unit area and average form factor of the soil microstructure generally decrease, the structural arrangement of the unit gradually tends to be orderly, and the average pore area, apparent void ratio and the number of pores generally show a decreasing trend; (3) under the action of a consolidation load, when the microstructure at a relatively large scale is basically stable, the microstructure at a smaller scale will continue to adjust; (4) the apparent void ratio has a good linear regression relationship with the conventional void ratio, and the apparent void ratio has a good exponential growth relationship with the compressibility.
Measuring Humility in an Indonesian Sample

Humility has been a neglected virtue in the social and psychological sciences. Owing to the nature of the construct itself, humility poses some special challenges to researchers wishing to assess individual differences. Although there have been significant strides in research in humility, especially in intellectual humility, this research has yet to test measures of humility in non-Western, religious populations. The present study builds on previous research by testing Indonesian versions of humility scales. We measure humility construct based on eight domains identified by Davis and Hook (2014), namely openness/lack of superiority, other-oriented/unselfish, admit mistakes/teachable, interpersonal modesty, accurate view of self, global humility, spiritual humility, and regulate need for status. The data was analyzed using Confirmatory Factor Analysis (CFA) (N=390). Among 44 items theorized to measure Humility, 8 items do not fit the model and are deemed as not valid, while the other 36 items are valid. The recommendation for future research is to further develop the instrument of humility as some factors still have very few items.
The Comparison Performance of Digital Forensic Tools Using Additional Root Access Options

Received December 06, 2021 Revised December 27, 2021 Accepted January 19, 2022 This research used MiChat and SayHi as materials for forensic investigations using three different tools, namely MOBILedit, Magnet Axiom, and Belkasoft. These three tools will show each performance in the forensic process. We also added a rooting process as an option if data cannot be extracted optimally even when using these three applications. The result of this study shows that the cases studied with processes without root access and with root access have the aim of complementing each other in obtaining evidence. So that these two processes complement each other's shortcomings. The main contribution of this research is a recommendation of a tool based on the best performance shown during the forensic process with rooting access and without rooting access. Based on the comparison, Magnet Axiom is superior with a total of 34 items of data found without root access, while MOBILedit is 30 items and 30 items for Belkasoft. While comparison using root access, Magnet Axiom and MOBILedit are superiors with a total of 36 items found in Magnet Axiom without root access, while MOBILedit is 36 items and 33 items for Belkasoft. Based on the test results, it can be concluded that the recommended tool according to the used scenario is Magnet Axiom.
1-Isobutanoil-2-isopropylisothiourea Phosphate, T1082: A Safe and Effective Prevention of Radiotherapy Complications in Oncology

The radioprotective effects of a new 1-isobutanoil-2-isopropylisothiourea derivative named T1082 are presented. Research methods included toxic characteristics, radioprotective activity (Till–McCulloch’s test and 30-day survival test) in γ-ray total-body-irradiated mice, and a clinical and histological study of the effect of T1082 on acute radiation skin reactions (RSR) in rats after a single or fractionated β-ray local irradiation. T1082 is more effective than its analogue, the NOS inhibitor T1023, at low concentrations and doses (1/12–1/8 LD10), both parenterally and intragastrically. In this case, its therapeutic index (LD50/ED50) reaches 30, and the optimal radioprotective doses (ED84–98—141–224 mg/kg) are an order less than the maximum tolerated doses—1/16–1/10 LD10. These properties allowed T1082, at a low intragastrical dose (160 mg/kg; 1/14 LD10), to significantly limit the severity of acute RSR after single (40 Gy) and fractionated (78 Gy) β-ray irradiation. The results confirm T1082 as one of the safest emergency radioprotectors and indicate the prospects for its further development as a pharmacological agent for the prevention of RT complications.
Influence of Temperature and Moisture on Free Vibration Behavior of Skew Laminated Composite Sandwich Panels with CNTRC Core

This paper presents the influence of temperature and moisture on the free vibration characteristics of skew laminated composite sandwich (SLCS) panels. The face sheets of the panels are made of graphite–epoxy composite, while the core consists of carbon nanotube-reinforced composite. The coupled hygro-elastic and thermo-elastic relations for the SLCS shells/panels are formulated using first-order shear deformation theory. The nonmechanical stiffness matrices are represented by the initial stress stiffness matrix developed using nonlinear strain–displacement relations. The temperature and moisture-dependent material properties are considered to analyze the laminated composite sandwich spherical, hyperbolic, ellipsoid, cylindrical Shells, and flat plates. Several numerical examples are comprehensively studied to establish the influence of temperature, moisture, the volume fraction of carbon nanotubes in the core material, functional gradation types, skew angle, and edge constraints on the vibration responses of SLCS shells. Further exploration is devoted to studying the combined effect of moisture, temperature, and the geometrical parameters such as length to width ratio, length to thickness ratio, radius-to-length ratio, and the core thickness to face sheet thickness ratios on the natural frequency of the skew laminated composite sandwich panels.
Fault location based on fault current amplitude comparison for active distribution network

The short circuit current properties of DER(Distributed Energy Resource) and its allowed capacity are analyzed. The relationship of short circuit current amplitude between faulty and healthy zones is analyzed and it is proposed to locate the fault of active distribution network by the comparison of short circuit current amplitude between both sides of a feeder section. The simulative results by MATLAB /Simulink show that,the proposed method can locate the fault when the allowed capacity of DER satisfies the voltage offset of point of common coupling.
TRPV4 Stimulation Level Regulates Ca2+-Dependent Control of Human Corneal Endothelial Cell Viability and Survival

The functional contribution of transient receptor potential vanilloid 4 (TRPV4) expression in maintaining human corneal endothelial cells (HCEC) homeostasis is unclear. Accordingly, we determined the effects of TRPV4 gene and protein overexpression on responses modulating the viability and survival of HCEC. Q-PCR, Western blot, FACS analyses and fluorescence single-cell calcium imaging confirmed TRPV4 gene and protein overexpression in lentivirally transduced 12V4 cells derived from their parent HCEC-12 line. Although TRPV4 overexpression did not alter the baseline transendothelial electrical resistance (TEER), its cellular capacitance (Ccl) was larger than that in its parent. Scanning electron microscopy revealed that only the 12V4 cells developed densely packed villus-like protrusions. Stimulation of TRPV4 activity with GSK1016790A (GSK101, 10 µmol/L) induced larger Ca2+ transients in the 12V4 cells than those in the parental HCEC-12. One to ten nmol/L GSK101 decreased 12V4 viability, increased cell death rates and reduced the TEER, whereas 1 µmol/L GSK101 was required to induce similar effects in the HCEC-12. However, the TRPV4 channel blocker RN1734 (1 to 30 µmol/L) failed to alter HCEC-12 and 12V4 morphology, cell viability and metabolic activity. Taken together, TRPV4 overexpression altered both the HCEC morphology and markedly lowered the GSK101 dosages required to stimulate its channel activity.
Impact of Lifestyle Modifications on Alterations in Lipid and Glycemic Profiles and Uric Acid Values in a Pediatric Population

Cardiometabolic risk factors are frequent in children and adolescents with excess weight. The aim of this study was to evaluate the effects of lifestyle modifications on alterations in lipid and glycemic profiles and uric acid values in a pediatric population at increased cardiovascular risk. The study involved 276 subjects with a mean age of 10.6 (2.3) years. Body mass index (BMI) z-score and biochemical parameters (serum low-density lipoprotein (LDL) cholesterol, triglycerides and uric acid and homeostasis model assessment to quantify insulin resistance (HOMA index)) were assessed at baseline and at the end of a median follow-up of 14.7 (12.4, 19.3) months. Throughout follow-up, all children received a non-pharmacological treatment based on increased physical activity, reduced sedentary activity and administration of a personalized, healthy and balanced diet. All children attended periodic quarterly control visits during follow-up. Multivariable statistical analyses showed that each BMI z-score point reduction at follow-up was associated with an 8.9 (95% CI −14.2; −3.6) mg/dL decrease in LDL cholesterol (p = 0.001), 20.4 (95% CI −30.0; −10.7) mg/dL in triglycerides (p < 0.001), 1.6 (95% CI −2.2; −1.0) in HOMA index (p < 0.001), and 0.42 (95% CI −0.66; −0.18) mg/dL in uric acid (p = 0.001) values. At each reduction of the BMI z-score by one point, the odds of presenting with insulin resistance and hyperuricemia at follow-up significantly decreased (OR 0.23, 95% CI 0.10–0.50, and OR 0.32, 95% CI 0.10–0.95, p < 0.001 and p < 0.05, respectively). Improvement of dietary habits and lifestyles may improve lipid and glycemic profiles and serum uric acid values in a pediatric population.
An Automatic Circuit Design Framework for Level Shifter Circuits

Although design automation is a key enabler of modern large-scale digital systems, automating the transistor-level circuit design process still remains a challenge. Some recent works suggest that deep learning algorithms could be adopted to find optimal transistor dimensions in relatively small circuitry such as analog amplifiers. However, those approaches are not capable of exploring different circuit structures to meet the given design constraints. In this work, we propose an automatic circuit design framework that can generate practical circuit structures from scratch as well as optimize the size of each transistor, considering performance and reliability. We employ the framework to design level shifter circuits, and the experimental results show that the framework produces novel level shifter circuit topologies and the automatically optimized designs achieve <inline-formula> <tex-math notation="LaTeX">$2.8\times $ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$5.3\times $ </tex-math></inline-formula> lower power-delay product (PDP) than prior arts designed by human experts.
A Study on the Basics Processes of Massive MIMO

Massive Multiple Input Multiple Output (MIMO) is a key technique used in 5G mobile communication systems; it aims to efficiently increase the spectral efficiency of the communication systems. Massive MIMO is a MIMO system with a massive number of antennas in the base station, it uses its large number of antennas to efficiently transmit and receive the signals between the base stations and the user equipment and maximize the spectral efficiency of the system. Massive MIMO is mainly composed of three important processes: channel estimation, uplink transmission (receive beamforming), and downlink transmission (transmit beamforming). Based on the effective channel estimation methods, the base station can process the signal to make efficient transmit and receive beamforming and provide good transmission and reception quality, which is measured by the spectral efficiency of the system. Many references present the basics of massive MIMO processes, including channel estimation, transmit beamforming and receive beamforming. This paper aims to present a cleared and concluded study on these basics massive MIMO processes. It presents different channel estimation methods and evaluates its performance based on the normalized mean square error. It also presents different receive and transmit beamforming techniques and evaluates its performance based on spectral efficiency.
