Reconfigurable Intelligent Surface-Based Symbiotic Radio for 6G: Design, Challenges, and Opportunities

Energy efficiency (EE) and spectrum efficiency (SE) are two key performance metrics in the sixth generation (6G) wireless communication networks due to the ultra-massive connectivity requirements in future Internet of Things scenarios such as smart cities and factories. Reconfigurable intelligent surface (RIS)-based symbiotic radio (SR) is a promising technology to simultaneously achieve high EE and SE. In this article, a comprehensive review of the RIS-based SR system is presented including the system architectures, operating principles, technical advantages, application scenarios and state-of-the-art transceiver design. Moreover, a star-QAM-aid-ed joint spatial modulation scheme is proposed to realize RIS-based SR and simulation results are provided to illustrate the performance of the proposed scheme. Finally, the critical design challenges for the implementation of RIS-based SR and some promising future research directions are discussed.
Feeding of Barbus cyclolepis Heckel, 1837 (Teleostei: Cyprinidae) and its relationship with benthic macroinvertebrate fauna in the Istranca Stream (İstanbul, Turkey)

The aims of the study are to determine what the organisms Barbus cyclolepis consume as food in its feeding environments and to compare prey consumption with prey abundance in the environment. The study was conducted in the Istranca Stream located in Istanbul (Turkey) during the spring and summer of 2012. A total of 142 B. cyclolepis specimens were captured and it is determined that 94 of them had full digestive tracts. Diet analyses of B. cyclolepis showed that its food spectrum consisted of 11 different food types, and the species was found to feed on insects, mainly Diptera (IRI%= 92.26%). The most abundant macroinvertebrate organisms in the environment were Diptera and Gastropoda. The electivity index of B. cyclolepis was positive for Diptera in the spring (E= 0.49), but the value was below the expected value of 0.6 for high selectivity. The electivity values for other macroinvertebrate groups, consumed in low proportions, were negative. In summer, the fish fed on Diptera, Plecoptera, and Trichoptera, but a high electivity index value was found only for Trichoptera (E= 0.87). Results showed that B. cyclolepis mainly consumed Diptera as food and did not consume Gastropoda, although it is the second most abundant macroinvertebrate group in the environment. A relationship was determined between the proportion of food groups consumed in the digestive tracts of fish and the ratios of macroinvertebrates in the environment, and as a result, it was specified that the fish was selective on Diptera.
Face Age Estimation Based on CSLBP and Lightweight Convolutional Neural Network

As the use of facial attributes continues to expand, research into facial age estimation is also developing. Because face images are easily affected by factors including illuminationand occlusion, the age estimationof faces is a challengingprocess. This paper proposes a face age estimationalgorithmbased on lightweight convolutional neural network in view of the complexity of the environment and the limitations of device computing ability. Improving face age estimation based on Soft Stagewise Regression Network (SSR-Net) and facial images, this paper employs the Center Symmetric Local Binary Pattern (CSLBP) method to obtain the feature image and then combines the face image and the feature image as network input data. Adding feature images to the convolutional neural network can improve the accuracy as well as increase the network model robustness. The experimental results on IMDB-WIKI and MORPH 2 datasets show that the lightweight convolutional neural network method proposed in this paper reduces model complexity and increases the accuracy of face age estimations.
Evolutionary history of the roan antelope across its African range

Phylogeographic studies on savanna ungulates have extensively evaluated genetic patterns mostly related to Pleistocene climatic oscillations. We address this subject through a comprehensive assessment across the pan‐African range of the roan antelope, assessing whether climatic oscillations or natural physical barriers play a predominant role in the evolutionary history of the species. We also address the spatial concordance of the genetic structure with the currently recognized subspecies.
The modern way of refractive index measurement of optical glass at SCHOTT

The refractive index is the most important property of optical glass. Therefore, refractive index measurement is a key characterization method also for process control. The requirements for refractive index control demand a fast and accurate measurement method for production control and a very high accurate measurement method for tightest requirements. For refractive index measurement two different measurement setups are common: the v-block refractometer for economic refractive index control up to the fifths digit and the spectral goniometer for high precision index measurement over a broad wavelength range from 185 nm to 2.325 μm up to the sixth digit. Providing Sellmeier dispersion equation data for individual measurements enables accurate interpolation of index data for arbitrary wavelengths for high precision applications. To cope with specific production requirements and the required high reliability of the measurements SCHOTT develops its own measurement setups. Both, the v-block system and the high precision spectral goniometer have been updated in recent time. To evaluate the accuracy SCHOTT participates in international round-robin tests. SCHOTT is also participating in the standardization of refractive index measurement methods for the optical industry. In this paper the current status of refractive index measurement of optical glasses at SCHOTT is presented.

IMPACT The goal of this article is to identify evidence-based building blocks for smart and sensible practices of policy design, public leadership and management, while recognizing that universal templates for success are not the right approach. It is critical that strategies to improve governance show appropriate sensitivity to context. The authors offer an alternative for high-level assessments of institutional qualities of ‘good government’. The article presents a practical toolkit to identify, assess, interpret, compare, and learn from concrete instances of public policy successes, highly successful public organizations, and collaborative, networked governance.
Autonomous Landing of Micro Unmanned Aerial Vehicles with Landing-Assistive Platform and Robust Spherical Object Detection

Autonomous unmanned aerial vehicle (UAV) landing can be useful in multiple applications. Precise landing is a difficult task because of the significant navigation errors of the global positioning system (GPS). To overcome these errors and to realize precise landing control, various sensors have been installed on UAVs. However, this approach can be challenging for micro UAVs (MAVs) because strong thrust forces are required to carry multiple sensors. In this study, a new autonomous MAV landing system is proposed, in which a landing platform actively assists vehicle landing. In addition to the vision system of the UAV, a camera was installed on the platform to precisely control the MAV near the landing area. The platform was also designed with various types of equipment to assist the MAV in searching, approaching, alignment, and landing. Furthermore, a novel algorithm was developed for robust spherical object detection under different illumination conditions. To validate the proposed landing system and detection algorithm, 80 flight experiments were conducted using a DJI TELLO drone, which successfully landed on the platform in every trial with a small landing position average error of 2.7 cm.
OPTIMIZATION OF STARCH GLYCOLATE AS NOVEL SUPERDISINTEGRANT IN THE FORMULATION OF GLIPIZIDE FAST DISSOLVING TABLETS THROUGH 23FACTORIAL DESIGN

Objective: To synthesize, characterize and evaluate starch glycolate as a superdisintegrant in the formulation of Glipizide fast dissolving tablets by employing 23 factorial designs. Methods: Starch glycolate was prepared and its physical and micromeritic properties were performed to evaluate it. The fast dissolving tablet of Glipizide was prepared by employing starch crotonate as a superdisintegrant in different proportions in each case by direct compression method using 23 factorial design for the evaluation of tablet parameters like disintegration and dissolution efficiency in 5 min. Results: The starch glycolate prepared was found to be fine, free-flowing and amorphous. Starch glycolate exhibited good swelling in water with a swelling index (10%). The study of starch glycolate was shown by fourier transform infrared spectra (FTIR). The drug content (100±5%), hardness (3.5–4 kg/sq. cm), and friability (<0.15%) was been effective with regard to all the formulated fast dissolving tablets employing starch glycolate. The disintegration time of all the formulated tablets was found to be in the range of 13±0.015 to 180±0.014 sec. The optimized formulation F8 had the least disintegration time i.e., 13±0.015 sec. The wetting time of the tablets was found to be in the range of 8±0.015 to 95±0.013 sec. The In vitro wetting time was less (i.e., 8±0.015s) in optimized formulation F8. The water absorption ratio of the formulated tablets was found to be in the range of 75±0.012 to 150±0.014%. The percent drug dissolved in the optimized formulation F8 was found to be 99.95% in 5 min. Conclusion: Starch glycolate was an efficient superdisintegrant for fast-dissolving tablets. The disintegration and dissolution efficiency of the fast dissolving tablets of glipizide was good and depended on the concentration of superdisintegrant employed i.e., starch glycolate, sodium starch glycolate, crospovidone. The formulated fast dissolving tablets of glipizide exhibited good dissolution efficiency in 5 min which can be used for the fast therapeutic action of glipizide.
Sublimation of organic-rich comet analog materials and their relevance in fracture formation

Aims. The morphology of cometary nuclei is the result of an ongoing evolution and can provide valuable information to constrain the composition of comets. In our laboratory experiments we investigated the morphological evolution of comet analog materials, which consist of volatile, dust, and organic components. The laboratory results are aimed to help understand the evolution of cometary surfaces. Methods. We used spherical particles of fly ash and mixtures of ice, glycine, and sodium acetate as analog materials in different mass ratios to reproduce observed cometary morphologies. The cohesive and gravitational properties in the laboratory are scaled to cometary conditions to draw meaningful conclusions from the experimental results. The samples were placed in a vacuum sublimation chamber, cooled down to below 150 K, and were insolated with an external light source. To analyze the morphology of the samples, a camera was used to monitor the alterations of the surface. Results. Organic components in volatile-rich samples can have a distinct adhesive effect after the volatiles sublimate. During the sublimation process the sample volume decreases and fractures form on the sample surface. Due to the stability of the remaining volatile-depleted material, significant cliff collapses or ejected particles were not observed in the laboratory.
Let’s Do the Time Warp Again: Non-linear time series matching as a tool for sequentially structured data in ecology

Ecological patterns are often fundamentally chronological. However, generalization of data is necessarily accompanied by a loss of detail or resolution. Temporal data in particular contains information not only in data values but in the temporal structure, which is lost when these values are aggregated to provide point estimates. Dynamic Time Warping (DTW) is a time series comparison method that is capable of efficiently comparing series despite temporal offsets that confound other methods. The DTW method is both efficient and remarkably flexible, capable of efficiently matching not only time series but any sequentially structured dataset, which has made it a popular technique in machine learning, artificial intelligence, and big data analytical tasks. DTW is rarely used in ecology despite the ubiquity of temporally structured data. As technological advances have increased the richness of small-scale ecological data, DTW may be an attractive analysis technique because it is able to utilize the additional information contained in the temporal structure of many ecological datasets. In this study we use an example dataset of high-resolution fish movement records obtained from otolith microchemistry to compare traditional analysis techniques with DTW clustering. Our results suggest that DTW is capable of detecting subtle behavioral patterns within otolith datasets which traditional data aggregation techniques cannot. These results provide evidence that the DTW method may be useful across many of the temporal data types commonly collected in ecology, as well other sequentially ordered “pseudo time series” data such as classification of species by shape. Keywords: classification, cluster analysis, data generalization, DTW, dynamic time warping, otolith chemistry, time series

Objective: The present study was aimed to develop a combinational floating tablet of curcumin and berberine HCl utilizing synthetic polymers synthetic HPMC K-15M and evaluate its various characteristics. Methods: The formulations were developed by the process of wet granulation and evaluated for drug content, content uniformity, floating lag time, total floating time, in vitro buoyancy studies, and in vitro drug release profile. A simultaneous estimation method for curcumin and berberine was developed using U. V spectroscopy. Results: The results clearly indicated that the tablets produced were having acceptable physical parameters. The absence of any drug/polymer/excipient interactions was confirmed using infrared spectroscopy. It was found that the drug content of was in between 96.22 to 99.45 % in all the formulations. Because of their low densities, in vitro floatability tests showed that most of the tablets floated for more than 8 h. The in vitro release studies confirmed the sustained release of more than 80 percent of drug contained within a period of 8 h. In vitro buoyancy was good in all three batches (F1-F3). The overall floating time for the F2 formulation was 24 h. After one month of storage at 40 °C and 75 percent RH, the F2 formulation showed no noticeable change in physical as well as pharmaceutical performance characteristics. Conclusion: Floating tablets of curcumin and berberine was successfully developed and had passed on various pharmaceutical parameters.

Vibration Analysis of a Piezoelectric Ultrasonic Atomizer to Control Atomization Rate

In this work, a mechanical vibrational analysis of an ultrasonic atomizer is carried out to control its atomization mass transfer rate. An ultrasonic atomizer is a device constructed with a piezoelectric ring coupled to a metallic circular thin plate with micro-apertures. The mechanism of mass transfer by atomization is a complex phenomenon to model because of the coupling effect between the fluid transfer and dynamic mechanics controlled by a piezoelectric vibrating ring element. Here, the effect of the micro-apertures shape of the meshed thin plate coupled to a piezoelectric ring during vibration, as well as the resonance frequency modes, are numerically studied using a finite element analysis and compared with theoretical and experimental results. Good correlations between the predicted and experimental results of the resonant frequencies and atomization rates were found.
First report of Erwina amylovora in Tuscany, Italy

2-years-old plants of Pyrus communis showing symptoms of fire blight disease were sampled in an orchard in Tuscany (Italy) during Autumn 2020. Plants were obtained the previous spring from a commercial nursery located in a region where the disease is present since 1994. The collected material was processed in the lab in order to verify the presence of the bacterium Erwinia amylovora, the causal agent of fire blight. Pure isolates showing white mucoid colonies and levan producers on Levan medium were putatively assimilated to E. amylovora. DNA was extracted from the cultures and analysed with three molecular assays, including duplex PCR of the 29-Kb plasmid pEA29 and the ams chromosomal region, sequencing of the 16S rDNA and recA gene regions, two real-time PCR assays on symptomatic plant tissues. All tests confirmed the presence of E. amylovora. Symptomatic and surrounding plants were removed and immediately destroyed according to the regional phytosanitary protocol. This outcome poses a serious threat for fruit orchards in the area.
Factors Affecting Turnover and Turnaway Intention of Journalists in South Korea

This study examined the factors affecting turnover and turnaway intention of newspaper journalists in South Korea through the lens of the push–pull–mooring framework. Survey results of 899 journalists showed that traffic boosting practices push journalists away from organizations. Particularly, senior journalists were more frustrated with the prevalence of traffic boosting practices, while juniors were more sensitive to growth potential and job security. Furthermore, ideological conflict between journalists and their organizations regarding political orientation was positively related to turnover intention. Meanwhile, regardless of the career length, journalists who enjoyed their coworkers were less likely to leave their jobs.
A ‘planning revolution’ or an ‘attack on planning’ in England: digitization, digitalization, and democratization

ABSTRACT This article focuses on the planning–technology nexus. Recent work explores the potential of digital technology in overcoming the longstanding limitations of a lack of public engagement and citizen empowerment in the planning process. In August 2020, the Government published a White Paper to democratize, digitize, and digitalize the planning system. We interrogate whether these radical reforms constitute a ‘planning revolution’ or an ‘attack on planning’; we focus on two important issues: democratic deficit and digital divide. The article examines how statements about digitization and digitalization may meet the Government’s desire to make the planning process more inclusive (i.e. equitable, fair, just) by empowering greater numbers of people to influence planning decisions for their local communities. In this agenda-setting article, we reflect on the English planning landscape; more broadly, we critically reflect on the values and political rhetoric involved in embracing technological innovations, and how these intersect with societal concerns.
Judging the legality of sexually violent tactics: a comparison between prosecuting attorneys in the United States and Colombia

ABSTRACT In order to study sexual violence internationally, it is helpful to understand similarities and differences in how sexual violence is conceptualised across countries. The current study examined prosecuting attorneys’ judgments about which sexual tactics legally qualify as sexual violence in two countries. Attorneys from the U.S. (n = 28) and Colombia (n = 24) evaluated whether 36 tactics would qualify as a sexual offense in their jurisdiction. Although Colombian and U.S. attorneys agreed on the legality of many tactics, Colombian attorneys judged more behaviours as criminal, on average, than U.S. attorneys. Within-country variations suggested that differences were due not only to different legal statutes, but also to different interpretations of laws. Open-ended responses illustrated sources of ambiguity, including lack of clarity about how much coercion is required and which behaviours indicate nonconsent. This suggests that vagueness within legal definitions may allow attorney judgements to be influenced by stereotypes and prejudices. PRACTICE IMPACT STATEMENT This study illustrates the vagueness of legal definitions of sexual violence in two countries—the United States and Colombia. This vagueness provides prosecuting attorneys with substantial power to interpret the law, and in this study, some attorney judgements of legality seemed to be influenced by stereotypes. Greater training for law students and attorneys about the realities of sexual violence may be helpful in undermining belief in rape myths that may inhibit attorneys from prosecuting certain sexual violence cases.
