RIS assisted wireless networks: Collaborative regulation, deployment mode and field testing

Field: Engineering (Physical Sciences)

Abstract In recent years, reconfigurable intelligent surfaces (RIS) have made significant progress in engineering application research and industrialization, as well as in academic research. However, the engineering application research field of RIS still faces several challenges. This article analyses and discusses the two deployment modes of RIS‐assisted wireless networks, namely network controlled mode and standalone mode. It also presents three typical collaboration scenarios of RIS networks, including multi‐RIS collaboration, multi‐user access, and multi‐cell coordination, which reflect the differences between the two deployment modes of RIS. The article proposes collaborative regulation mechanisms for RIS and analyses their applications in the two network deployment modes in‐depth. Furthermore, the article establishes simulation models of three scenarios and provides rich numerical simulation results. An actual field test environment is also built, where a specially designed and processed RIS prototype was used for preliminary field test and verification. Finally, this article puts forward future trends and challenges.
Can Aikido Help With the Comprehension of Physics? A First Step Towards the Design of Intelligent Psychomotor Systems for STEAM Kinesthetic Learning Scenarios

Field: Computer Science (Physical Sciences)

ducational stakeholders are promoting the development of educational approaches that go beyond classroom and engage learners in acquiring science, technology, engineering and mathematical (STEM) concepts with the support of arts (known as STEAM). Taking into account the recent advances in wearable technology to sense human motion, psychomotor intelligent tutoring systems (where students' motion interactions are collected with sensors and used to provide personalized vibrotactile feedback to support the learning process) can be designed to teach STEM concepts in a kinesthetic way. In order to investigate the feasibility of this approach, in this paper we have carried out an empirical study with high school students to determine if watching specific techniques of the defense martial art Aikido (which makes use of different types of rectilinear and curvilinear motion) can be used to learn some concepts of physics. Nonetheless, other martial arts could be used for similar purposes, but further studies are needed. Analyzing the outcomes of the 30 participants that took part in the study, we conclude that the proposed approach seems to have benefits in the learning of STEM concepts, and thus, the usage of martial arts deserves to be further investigated in STEAM kinesthetic learning scenarios, which can also consider the students' affective state.
Lesbian women disrupting gendered, heteronormative discourses of motherhood, marriage, and divorce

Field: Social Sciences (Social Sciences)

Despite shifts in societal attitudes, lesbian women who separate and divorce still must cope with recriminating societal messages that blame and condemn them for not conforming to the gendered heteronormative dictate of married motherhood. Guided by feminist theory, we conducted a qualitative analysis of narratives from 17 adoptive lesbian mothers who had dissolved their relationship. The women's narratives revealed five cultural discourses that they variously embraced, resisted, or disrupted: (1) the ideology of the good mother; (2) divorce is bad for children; (3) marriage is the ideal way to live; (4) couples should stay together for the children; and (5) lesbian ex-lovers should be lifelong friends. All women embraced the cultural belief in "the good mother," which is the linchpin of gendered oppression, but they were much more disruptive regarding the remaining four discourses surrounding marriage, divorce, and lesbian relationships. Their assessments of life after separation revealed that divorce can actually be better than marriage for their children; marriage is often overrated; having children can complicate a marriage; and remaining friends with one's ex-partner is not always desirable. The feminist tenet that oppression and agency coexist was revealed as the women both engaged and resisted dominant cultural narratives in order to navigate the dilemmas of crafting a new life for themselves and their children post-divorce.

Herein is described a new species of Rorippa (R. apetala, Brassicaceae) discovered on the River Seom-gang in Wonju-si, Gangwon-do, Korea. The new species is distinct from the closely-related species, R. palustris and R. globosa, by having adventitious buds on the surface of rhizome-type roots during the fruiting season, usually absent or rarely 1-4, if present then atrophy petals, obpandurate fruits, and seeds usually empty or rarely 1-2 per locule. The key to these species is provided.
Phenotypic Characterization of Adenovirus Type 12 Temperature‐Sensitive Mutants in Productive Infection and Transformation

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Eleven temperature‐sensitive mutants of adenovirus type 12, capable of forming plaques in human cells at 33 C but not at 39.5 C, were isolated from a stock of a wild‐type strain after treatment with either nitrous acid or hydroxyl‐amine. Complementation tests in doubly infected human cells permitted a tentative assignment of eight of these mutants to six complementation groups. Temperature‐shift experiments revealed that one mutant is affected early and most of the other mutants are affected late. Only the early mutant, H12 ts 505, was temperature sensitive in viral DNA replication. Infectious virions of all the mutants except H12 ts 505 and two of the late mutants produced at 33 C, appeared to be more heat labile than those of the wild type. Only H12 ts 505 was temperature sensitive for the establishment of transformation of rat 3Y1 cells. One of the late mutants (H12 ts 504) had an increased transforming ability at the permissive temperature. Results of temperature‐shift transformation experiments suggest that a viral function affected in H12 ts 505 is required for “initiation” of transformation. Some of the growth properties of H12 ts 505‐transformed cells were also temperature dependent, suggesting that a functional expression of a gene mutated in H12 ts 505 is required to maintain at least some aspects of the transformed state.

Economics of Pest Management

Field: Economics, Econometrics and Finance (Social Sciences)

Integrated pest management (IPM) has a responsibility to man and his environment, i.e., to minimize as much as possible the introduction of hazardous chemical toxicants into the environment. The understanding of the economic threshold is basic to IPM systems. In those areas where populations have risen above economic threshold levels, chemical insecticides have and will for some time in the foreseeable future play a key role in the management of insect populations. The economic and environmental assessment of IPM programs must be included as a key component in all research and implementation stages. A research and demonstration project conducted in the Trans-Pecos of West Texas has provided some interesting opportunites for economic production of cotton. Net returns for conventional production were estimated to be $37.27 per acre while under the IPM program net returns were estimated to be $55.77, or an increase of $18.50 per acre.
Improved chemotactic ability of neonatal polymorphonuclear cells induced by mild membrane rigidification

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Membrane lipid fluidity of peripheral blood polymorphonuclear cells (PMNs) of 24 newborn infants, 2–4 days after birth, was determined by steady-state fluorescence polarization with 1,6-diphenyl 1,3,5-hexatriene (DPH) as a probe and compared with that of PMNs from 23 adults. Measurements with intact cells, which correspond to all cellular lipid domains, did not display any statistically significant difference between PMNs of the two groups. However, application of bixinoyl glucosamine, a membrane-impermeable fluorescence quencher, revealed that the PMN plasma membrane of the newborn is about 23% more fluid than that of the adult. Total cholesterol-to-phospholipid ratio of newborn PMNs was found to be lower by about 10% than that of the adult, which could account for the difference in their plasma membrane fluidity. The possible implication of this finding for the deficit in chemotactic ability of leukocytes from newborns was tested with neonatal PMNs that have incorporated cholesteryl hemisuccinate (CHS), an efficient plasma membrane rigidifier. In all neonatal PMNs tested a mild incorporation of CHS (0.5–1 min incubation in 50 μg/ml dispersion) caused a significant improvement in their net chemotaxis, from an average value of 28 ± 7 to 43 ± 11. Longer incubations with CHS caused a gradual decrease in chemotactic ability that approached the basal level after about 5 min incubation. The net chemotaxis in adult PMNs was significantly higher than that of neonatal PMNs (72 ± 13) and was gradually inhibited by incorporation of CHS without any initial augmentation. Based on these results it was estimated that about 27% of the chemotactic deficit of neonatal PMNs is mediated by their immature fluid membrane.

How cells wrap around coronavirus-like particles using extracellular filamentous protein structures

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Nanoparticles, such as viruses, can enter cells via endocytosis, a process by which the cell membrane wraps around them. The role of nanoparticle size and shape on endocytosis has been well studied, but the biophysical details of how extracellular proteins on the cell membrane surface mediate uptake are less clear. Motivated by recent discoveries regarding extracellular vimentin in viral and bacterial uptake and the structure of coronaviruses, we construct a computational model with a cell-like and virus-like construct containing filamentous protein structures protruding from their surfaces. We study the impact of these additional degrees of freedom on viral wrapping. The cell surface is modeled as a deformable sheet with bending rigidity, and extracellular vimentin as semiflexible polymers, or extracellular components (ECC), placed randomly on the sheet. The virus is modeled as a deformable shell that also has explicit, freely rotating spike filaments on its surface. Our results indicate that cells with optimally populated filaments are more susceptible to infection as they take up the virus more quickly and utilize a relatively smaller area of the cell surface. At optimal ECC density, the cell surface forms a fold around the virus, which is faster and more efficient at wrapping than localized crumples. Additionally, cell surface bending rigidity aids in the generation of folds by increasing force transmission across the surface. Changing other mechanical parameters, such as the stretching stiffness of filamentous ECC or virus spikes, can result in localized crumple formation on the cell surface. We conclude with the implications of our study on the evolutionary pressures of virus-like particles, with a particular focus on the cellular microenvironment.
Importance of provoked spasms at the sites of nonobstructive stenosis as well as at the sites of obstructive stenosis in patients with obstructive coronary arteries and coronary spasm

Field: Medicine (Health Sciences)

Objectives There are few reports regarding the prognosis in patients with obstructive coronary artery disease (OCAD) and vasospastic angina (VSA). This study investigated the clinical characteristics and clinical outcomes in patients with VSA and OCAD, especially regarding provoked spasm phenotypes and sites. Methods This was a retrospective, observational, single-center study of 403 patients with typical or atypical angina-like chest pain undergoing acetylcholine (ACH) spasm provocation testing and OCAD. An obstructed coronary artery was defined as ≥50% luminal narrowing. We defined positive epicardial spasm as ≥90% transient stenosis and usual chest symptoms or ischemic ECG changes. Results Among these 403 patients with OCAD, positive spasm by intracoronary ACH testing was observed in 196 patients (49%), whereas negative spasm was found in the remaining 207 patients (51%). The clinical outcomes in the patients with OCAD and provoked spasm were not different according to the provoked-spasm phenotypes. Furthermore, the clinical outcomes were unsatisfactory in the patients with spasm at the site of nonobstructive lesion alone compared with those with spasm at the site of obstructive and nonobstructive lesions. Conclusion We should precisely diagnose patients with OCAD who have provoked spasm by using intracoronary ACH testing and medicate the nonobstructive vessels in patients with OCAD and VSA under optimal coronary vasodilators.
Abstract Light Source Interpolation for Sparsely Sampled Reflectance Fields

Field: Computer Science (Physical Sciences)

In this paper we address the problem of relighting with sparsely sampled reflectance fields. We present a technique that approximates the correct result of relighting from intermediate light source positions. The acquisition of reflectance fields is a time consuming process, and typically the sampling resolution in the light source positions is rather limited. As a consequence, smoothly moving highlights and shadows due to relighting with a moving light source are hard to generate. Using light source interpolation, densely sampled reflectance fields can be simulated, enabling relighting with area light sources and smooth animation of highlights and shadows. Using light source interpolation we can relight with arbitrarily sampled 4D incident light fields from complex or near-by light sources. 1

A Longitudinal Data Analysis of the Effect of Driving Distance on Scoring Average in Golf

Field: Mathematics (Physical Sciences)

The purpose of this study was to analyze the longitudinal effect of driving distance on scoring average in PGA tour. For this study, data were taken from official PGA Tour web site. They were longitudinal data over 33 years(1980-2012) since driving distance and scoring average have been measured repeatedly every year. Ranks of the player were considered as subjects. A linear mixed model was applied to the data to estimate cross-sectional as well as longitudinal effect of driving distance on scoring average. The estimates of the linear mixed model showed that there was a difference between cross-sectional and longitudinal effect. Therefore, if we use the ordinary least squares of regression analysis to get the effect of driving distance on scoring average, we would have wrong information about the relationship. From the longitudinal effect it can be concluded that scoring average has decreased about .73 significantly as driving distance has increased 33.27 yards longitudinally.
Variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress

Field: Agricultural and Biological Sciences (Life Sciences)

The variation of some growth, agronomical and biochemical parameters of Vigna unguiculata (L. Walp) under salinity stress were investigated in the greenhouse and farm conditions. Plants were subjected to 0, 50, 100 and 200 mM NaCl. The increases of NaCl in the culture medium significantly (P< 0.001) decreased the growth parameters (number of leaves, noose diameter, leaf area and stem height), dry biomass (roots, shoots and total), chlorophyll contents and micronutrients (Zn, Fe and Mn) from 100 mM NaCl. Macronutrients (K, Ca and Mg) and K/Na ratio significantly (P < 0.001) decreased in plant partitioning with increasing salinity. The metabolites (proline, total soluble carbohydrates, soluble proteins, total free amino acids, total phenolic and flavonoids contents) significantly (P < 0.001) increased from 50 mM NaCl in variety Ekomcalle compared to Mouala GG and could be considered as biochemical indicators of early selection and osmotic adjustment ability for salt tolerant plants. At 50 mM NaCl, a relative tolerance of variety Ekomcalle compared to Mouala GG for all agronomic parameters (the flowering time, number of flowers per plant, number of pods/plant, number of seeds/pod, pod yield, seed yield and harvest index) was observed suggesting that Ekomcalle could increase cowpeas production on salty soils. Key words: Vigna unguiculata, salinity, growth, metabolites, mineral uptake, agronomic parameters.

A193 : design of a compact loading machine

Field: Engineering (Physical Sciences)

A193 explore the use of Modular Product Design that is coupled with Modular Function Deployment to design and fabricate a new compact loading machine that can be integrated with an existing polariscope. Existing loading machine are unable to fully integrate with existing polariscope, hence slowing further researches on studies of how a material’s optical properties are affected when it is subjected to loading. However, the newly designed and fabricated compact loading machine is able to integrate with the existing polariscope and also provide qualitatively accurate types of loading, which are 2-point loading, 3-point loading, 4-point loading and also tensile loading. With such capabilities, the loading machine is able to aid in future studies of materials’ optical properties.
