Inclusion of Processed Rice Hulls as Insoluble Fiber in the Diet on Performance and Digestive Traits of Japanese Quails

To study the influence of processing of rice hulls (RH), and inclusion of additional fiber in the semipurified diet on the performance and digestive traits of quails from 7 to 35 day of age; Seven treatments were arranged in a completely randomized design, with 7 sources of fiber (none, 3% raw RH, 3% RH soaked in distilled water, 3% RH boiled in water contained NaCl, 3% autoclaved RH, 3% of two Micronized insoluble fibers) and 5 bird each. Each treatment was replicated four. Growth traits were recorded; digestive traits and litter moisture were measured. Supplementation of processed rice hulls (PRH) was associated with increases in daily body weight gain and feed conversion ratio and decrease in feed intake throughout the experimental period (P<0.01). As processing levels increased, the relative weight of digestive organs was increased (P<0.01). Supplementation of processed rice hulls resulted in increases in the intestinal villus height, villus thickness, villus height: crypt depth ratio and number of goblet cells, and decrease in litter moisture (P<0.01). These findings indicated that each RH variety possesses different chemical and physicochemical properties upon processing levels that is suitable for applications in poultry feeds. The Inclusion of 3% PRH in feed resulted in the greatest improvements in quail performance, intestinal morphology, and litter moisture.
Effects of Bi 2 O 3 and Nb 2 O 5 on the magnetic properties of Ni -Zn ferrites and lithium ferrites

The effects of the additives Bi 2 O 3 and Nb 2 O 5 on the sintering behavior and magnetic properties of Ni-Zn ferrites and lithium ferrites have been investigated by examination of microstructure and by measurements of permeability, loss factor and hysteresis curve. The additive Bi 2 O 3 enhances the sintering by forming a liquid phase in the ferrites, The additive Nb 2 O 5 enhances the sintering by increasing bulk diffusion due to the increased vacancy concentration which is accompanied by the solubility of Nb5+in the ferrites. Both additives leave microvoids and secondary phase precipitates in the grains when the sintering temperature is high. When the sintering temperature is low and the grain boundary mobility is small, however, Nb 2 O 5 still leaves defects in the grains but Bi 2 O 3 does not. Thus the μQ product of Ni-Zn ferrites increases when the right amount of Bi 2 O 3 is added and decreases when Nb 2 O 5 is added. On the other hand, the square-loop properties of the lithium ferrites improve when the right amount of Nb 2 O 5 is added and degrade when Bi 2 O 3 is added.
The effects of long-term menstrual pain on pain empathy in the women with primary dysmenorrhea.

ABSTRACT Primary dysmenorrhea (PDM) is not only a painful experience but also affects the psychological and affective states of women. Neuroimaging studies have revealed shared neural substrates for somatic and empathic pains in healthy subjects. However, little is known about the relationship between pain intensity and pain empathy in pain disorders. The cyclic nature of PDM makes it a unique model for investigating this issue during a patients' pain phase. To study how long-term pain modulates empathy for pain, T1-weighted MRI scans were obtained in 39 PDM patients and 41 matched female healthy controls during menstruation. Subjects viewed static visual stimuli of the limbs submitted to painful and non-painful stimulation to solicit empathy. The visual analogue scale for pain intensity and the Interpersonal Reactivity Index for empathic ability were also obtained. We found that women with PDM exhibited higher pain empathy compared with the controls. The anterior insula and brain regions related to sensory discrimination with decreased gray matter volumes were not only shared but also acted as a mediator between pain intensity and pain empathy in PDM patients. In addition, the general linear modeling analysis revealed that long-term pain experience was a more important factor to pain empathy compared with pain intensity. This indicated that long-term pain may cause maladaptive brain structural plasticity, which may further affect psychological adjustment to bring patients more vivid pain when they witness suffering and distress in others.
Halloysite clay minerals – a review

Abstract Halloysite clay minerals are ubiquitous in soils and weathered rocks where they occur in a variety of particle shapes and hydration states. Diversity also characterizes their chemical composition, cation exchange capacity and potassium selectivity. This review summarizes the extensive but scattered literature on halloysite, from its natural occurrence, through its crystal structure, chemical and morphological diversity, to its reactivity toward organic compounds, ions and salts, involving the various methods of differentiating halloysite from kaolinite. No unique test seems to be ideal to distinguish these 1:1 clay minerals, especially in soils. The occurrence of 2:1 phyllosilicate contaminants appears, so far, to provide the best explanation for the high charge and potassium selectivity of halloysite. Yet, hydration properties of the mineral probably play a major role in ion sorption. Clear trends seem to relate particle morphology and structural Fe. However, future work is required to understand the possible mechanisms linking chemical, morphological, hydration and charge properties of halloysite.
Flying colloidal carpets

DNA plays a special role in polymer science not just because of the highly selective recognition of complementary single DNA strands but also because natural DNA chains can be made very long, yet perfectly monodisperse. Solutions of such long DNA chains are widely used as model systems in polymer science. Here, we report the unusual self-assembly that takes place in systems of colloids coated with very long double-stranded DNA. We find that colloids coated with such long DNA can assemble into unique “floating” crystalline monolayers that are suspended at a distance of several colloidal diameters above a weakly adsorbing substrate. The formation of these monolayers does not depend on DNA hybridization. Floating colloidal structures have potentially interesting applications as such ordered structures can be assembled in one location and then deposited somewhere else. This would open the way to the assembly of multi-component, layered colloidal crystals.
Radiative power of a dipole in the proximity of a dielectric interface: a case study of a quantum-dot exciton transition dipole

We theoretically simulate the radiative power of an emitting dipole near a dielectric interface. When the dielectric constant of the dipole resting medium is larger than that of the substrate/dielectric interface, the radiative power is perturbed strongly at less than λ/2π by the interface due to the imposed boundary conditions on the plane waves, rather than the evanescent waves. The radiative power of an emitter is also sensitive to the dipole orientation in the proximity of the interface. Previous experimental results on the distance-dependent exciton lifetime of quantum dots in the proximity (⩽35 nm) of a dielectric interface are considered and explained using the simulated results of radiative power for an emitting dipole.
Structure and physical properties of epoxide‐treated tussah silk fibers

The structure and physical properties of tussah silk fibers from Antheraea pernyi treated by ethyleneglycol diglycidylether (E) and glycerin diglycidylether (G) as modifying agents were discussed in relation to the increasing weight gain values. It was suggested that the epoxide treatment does not affect directly the crystalline regions but causes a decrease of molecular orientation in the amorphous regions. Both birefringence and isotropic refractive index of tussah silk fibers decreased by the reaction with epoxides. The extent of decrease of strength and elongation depends on the kind of epoxide and on the weight gain value.
Speech recognition based on concatenated acoustic feature and lightGBM model

In this paper, we focus on the application of the LightGBM model for audio sound classification. Though convolutional neural networks (CNN) generally have superior performance, LightGBM model possess certain notable advantages, such as low computational costs, feasibility of parallel implementations, and comparable accuracies over many datasets. In order to improve the generalization ability of the model, data augmentation operations are performed on the audio clips including pitch shifting, time stretching, compressing the dynamic range and adding white noise. The accuracy of speech recognition heavily depends on the reliability of the representative features extracted from the audio signal. The audio signal is originally a one-dimensional time series signal, which is difficult to visualize the frequency change. Hence it is necessary to extract the discernible components in the audio signal. To improve the representative capacity of our proposed model, we use the Mel spectrum and MFCC (Mel-Frequency Cepstral Coefficients) to select features as twodimensional input to accurately characterize the internal information of the signal. The techniques mentioned in this paper are mainly trained on Google Speech Commands dataset. The experimental results show that the method, which is an optimized LightGBM model based on the Mel spectrum, can achieve high word classification accuracy.
Epidermal layer recognition of optical coherence tomography skin images

Epidermal layer recognition is an effective way to diagnose the severity of psoriasis and other skin diseases. Optical coherence tomography (OCT) is a non-invasive imaging modality that acquires images of tissue in vivo and plays an important role in detecting skin diseases and assessing therapeutic effects. In this paper, a method for epidermal layer recognition of OCT skin images is proposed. Firstly, the skin surface is obtained based on the axial gradient map. Then the original image is flattened according to the estimated skin surface. And the potential region of the dermo-epidermal junction (DEJ) is obtained according to the mean column signal. Finally, the epidermal layer is identified by topology transmission and seed filling. The method can automatically segment the curved mastoid structure of the DEJ which is suitable for OCT images of skin with weakened signal intensity of dermis due to dermatitis or other diseases.
Remote sensing vehicle detection based on embedded system

At present, remote sensing image vehicle detection based on deep learning has achieved certain results, but most of them rely on powerful PC computing power and cannot be deployed in satellites, so they cannot provide support for satellite in-orbit detection. Aiming at this problem, this paper proposes a remote sensing image vehicle detection method based on YOLOv5 model and successfully deploys it in Jetson TX2 embedded equipment that can be deployed on a satellite platform. Experiments have proved that the algorithm proposed in this article detects vehicle targets in a 12000*12000 pixels wide remote sensing image in an embedded device, and the detection time is only about 1 minute and 20 seconds at the fastest.
Commercial Video Games in School Teaching: Two Mixed Methods Case Studies on Students’ Reflection Processes

Commercial video games are popular entertainment media and part of students’ media reality. While commercial video games’ main purpose is not learning, they nonetheless could and should serve as objects of reflection in formal educational settings. Teachers could guide student learning and reflection as well as motivate students with commercial video games, but more evidence from formal educational settings is required. We conducted two mixed methods case studies to investigate students’ reflection processes using commercial video games in regular formal high school teaching. In a double lesson, 29 students of a 10th-grade biology course (Study 1) and 17 students of a 12th-grade advanced course on history (Study 2) played and discussed a commercial video game related to the current curricular topic. We examined the reflection processes of students in terms of their reactions to the teachers’ game-related statements and questions. Regarding teachers’ statements, students discussed several topics related to game enjoyment and the games’ representation of topic-related content. Regarding teachers’ questions, students discussed multiple goals in each game, how the games represented topic-related content, and how the games could be appropriate for learning. In Study 2, students additionally discussed emotions, stereotypes, violence, and the narrative related to the digital history game. We found that the discussions provided students opportunities to reflect on their game experiences and the current curricular topic as well as to practice media criticism. We further provide quantitative results on students’ perceived topic knowledge, on several facets of their learning motivation, and on their acceptance of video games. Overall, our findings illustrate the educational value of using commercial video games as objects of reflection.
Ostwald Ripening of Two-Phase Mixtures

Phase-separation processes frequently result in a polydisperse mixture of two phases of nearly equilibrium compositions and volume fractions. Such mixtures can also be created artificially by irradiating materials to create voids or, as is done in liquid phase sintering processes, by mixing together powders of different composition. Despite the nearly equilibrium state of the two-phase system, the mixture is not in its lowest energy state. This is because of the polydisperse nature of the mixture itself and the presence of a nonzero interfacial energy. Thus in the absence of elastic stress, the total interfacial area of the system must decrease with time in order for the system to reach thermodynamic equilibrium. There are many ways the system can reduce this excess interfacial area. The process of interest here is when the interfacial area is reduced via a diffusional mass transfer process from regions of high interfacial curvature to regions of low interfacial curvature. This interfacial area reduction process is commonly called coarsening, or Ostwald ripening, after the physical chemist W. Ostwald, who first described the process (I). This interfacial energy driven mass transfer process can significantly alter the morphology of the two-phase mixture. In general, the average size-scale of the mixture must increase with time and the number of second­ phase domains, or particles, must decrease with time. An example of an Ostwald ripening process is shown in Figure 1. The upper row of micro­ graphs shows the evolution of Sn-rich solid particles in an isothermal Pb­ Sn eutectic liquid as a function of time at constant magnification. Evident
Spatio-Temporal Variations of Winter Phytoplankton Blooms Northwest of the Luzon Island in the South China Sea

Phytoplankton is a key component of marine ecosystems. Winter phytoplankton blooms are frequently observed northwest of Luzon Island in the South China Sea. In this study, with the multi-satellite merged ocean color remote sensing data from November 1999 to February 2015, we examine the spatial and temporal changes of chlorophyll-a (Chl-a) concentration and further investigate its response to physical environment parameters including wind speed, Ekman transport, Ekman pumping velocity, sea surface temperature, and sea level anomalies in the region northwest of Luzon Island. The main factors affecting the distribution of Chl-a are discussed by using the partial correlation analysis and multiple stepwise linear regression analysis. The results show that centers of winter Chl-a blooms northwest of Luzon Island often occur near 119.5°E, 19.5°N. The significant multiple correlation (r = 0.76, p < 0.01) between Chl-a and oceanic conditions indicates that both the wind component parallel to the coastline and the wind stress curls enhance the winter upwelling in the study area, consistent with previous studies. A novel finding in the present study is that the winter bloom center is located north of the upwelling center, attributed to the advection effect of the northward background coastal flow.

STAT3 Suppresses Cardiomyocytes Apoptosis in CVB3-Induced Myocarditis Via Survivin

Background: Viral myocarditis (VMC) is a common inflammatory cardiovascular disease with unclear mechanisms, which mainly affects children and adolescents. Apoptosis is the key to CVB3-induced myocarditis, and blocking this process may be beneficial to the therapy of VMC. Hence, this study aimed to explore the protective function of STAT3 on cardiomyocyte apoptosis of VMC and its underlying mechanisms. Methods and Results: In this research, we confirmed that STAT3 was significantly activated in both animal and cell models of VMC. To further clarify what role did STAT3 play in VMC, AG490, an inhibitor of STAT3, was used to suppress p-STAT3. Our results demonstrated that decreased expression of p-STAT3 caused by AG490 significantly aggravated severity of VMC with elevated myocardial inflammation, deteriorative ventricular systolic function and increased mortality. It suggested that STAT3 plays a protective role in VMC. To further identify the anti-apoptosis impact that activated STAT3 made, we constructed lentivirus to regulate the expression of STAT3 in NMCs. We found that up-regulated activated STAT3 attenuated cardiomyocyte apoptosis, but down-regulated one aggravated that, which verified activated STAT3 played an anti-apoptosis role in VMC. Following that, we explored what elements are involved in the anti-apoptotic mechanism of activated STAT3 by using survivin inhibitor YM155. The result showed the anti-apoptotic effect of activated STAT3 does not work in the case of survivin inhibition. Conclusion: Our findings demonstrated STAT3 by targeting survivin alleviated cardiomyocyte apoptosis in CVB3-induced myocarditis.
Role of Cardiac A2A Receptors Under Normal and Pathophysiological Conditions

This review presents an overview of cardiac A2A-adenosine receptors The localization of A2A-AR in the various cell types that encompass the heart and the role they play in force regulation in various mammalian species are depicted. The putative signal transduction systems of A2A-AR in cells in the living heart, as well as the known interactions of A2A-AR with membrane-bound receptors, will be addressed. The possible role that the receptors play in some relevant cardiac pathologies, such as persistent or transient ischemia, hypoxia, sepsis, hypertension, cardiac hypertrophy, and arrhythmias, will be reviewed. Moreover, the cardiac utility of A2A-AR as therapeutic targets for agonistic and antagonistic drugs will be discussed. Gaps in our knowledge about the cardiac function of A2A-AR and future research needs will be identified and formulated.
Integration of Transcriptional and Post-transcriptional Analysis Revealed the Early Response Mechanism of Sugarcane to Cold Stress

Cold stress causes major losses to sugarcane production, yet the precise molecular mechanisms that cause losses due to cold stress are not well-understood. To survey miRNAs and genes involved in cold tolerance, RNA-seq, miRNA-seq, and integration analyses were performed on Saccharum spontaneum. Results showed that a total of 118,015 genes and 6,034 of these differentially expressed genes (DEGs) were screened. Protein–protein interaction (PPI) analyses revealed that ABA signaling via protein phosphatase 2Cs was the most important signal transduction pathway and late embryogenesis abundant protein was the hub protein associated with adaptation to cold stress. Furthermore, a total of 856 miRNAs were identified in this study and 109 of them were differentially expressed in sugarcane responding to cold stress. Most importantly, the miRNA–gene regulatory networks suggested the complex post-transcriptional regulation in sugarcane under cold stress, including 10 miRNAs−42 genes, 16 miRNAs−70 genes, and three miRNAs−18 genes in CT vs. LT0.5, CT vs. LT1, and CT0.5 vs. LT1, respectively. Specifically, key regulators from 16 genes encoding laccase were targeted by novel-Chr4C_47059 and Novel-Chr4A_40498, while five LRR-RLK genes were targeted by Novel-Chr6B_65233 and Novel-Chr5D_60023, 19 PPR repeat proteins by Novel-Chr5C_57213 and Novel-Chr5D_58065. Our findings suggested that these miRNAs and cell wall-related genes played vital regulatory roles in the responses of sugarcane to cold stress. Overall, the results of this study provide insights into the transcriptional and post-transcriptional regulatory network underlying the responses of sugarcane to cold stress.
Design and Synthesis of Single-Actuator Walking Robots via Coupling of Linkages

This paper deals with the development of single actuator walking robots designed by coupling of two mechanisms. The advantages of such robots are the simplicity of the design and its control system. In this paper, three various design concepts are carried out via coupling of two units which are four-bar linkages, slider-crank mechanisms, and a cam mechanism and a pantograph linkage. The geometrical syntheses of these mechanisms have been analyzed, and based on them, analytical and numerical methods have been adopted to ensure the reproduction of given trajectory similar to the human walking gait. Three single-actuator robots have been designed based on these mechanisms where two of them can be easily reconfigured to reproduce gaits with different lengths or even tilted gaits which make the robot able to climb stairs. All suggested design concepts have been validated through CAD simulations carried out via ADAMS software.
Nuclear Receptors in Asthma: Empowering Classical Molecules Against a Contemporary Ailment

The escalation in living standards and adoption of ‘Western lifestyle’ has an allied effect on the increased allergy and asthma burden in both developed and developing countries. Current scientific reports bespeak an association between allergic diseases and metabolic dysfunction; hinting toward the critical requirement of organized lifestyle and dietary habits. The ubiquitous nuclear receptors (NRs) translate metabolic stimuli into gene regulatory signals, integrating diet inflences to overall developmental and physiological processes. As a consequence of such promising attributes, nuclear receptors have historically been at the cutting edge of pharmacy world. This review discusses the recent findings that feature the cardinal importance of nuclear receptors and how they can be instrumental in modulating current asthma pharmacology. Further, it highlights a possible future employment of therapy involving dietary supplements and synthetic ligands that would engage NRs and aid in eliminating both asthma and linked comorbidities. Therefore, uncovering new and evolving roles through analysis of genomic changes would represent a feasible approach in both prevention and alleviation of asthma.
