Quenching Vibration on a Symmetric Laminated Composite Plate Excited by Multiple Harmonics Using Inerter-Based Dynamic Vibration Absorbers

Field: Engineering (Physical Sciences)

Abstract In this article, a simple and efficient method is developed to quench the steady-state vibration of a symmetric laminated composite rectangular plate subjected to multiple harmonics with distinct excitation frequencies. The introduction of the inerter into the traditional dynamic vibration absorber enlarges the solution space for both the feasible attachment locations and the absorber parameters. For a given set of attachment locations, when the traditional vibration absorbers yield physically unrealizable absorber parameters, i.e., negative absorber parameters, an inerter-based vibration absorber can be used such that the absorber parameters become strictly positive. Using the assumed modes method, the governing equations of the laminated composite plate carrying the inerter-based dynamic vibration absorbers are first formulated. A set of constraint equations is established by enforcing nodes at user-specified locations on the plate. Harmonic excitations consisting of a single or multiple distinct excitations are considered. In addition, two attachment scenarios are analyzed: when the attachment and node locations coincide, and when they are distinct. Numerical experiments show that the absorbers’ parameters can be readily determined for both cases, and the proposed method can effectively enforce the desired node locations when the plate is subjected to either a single or multiple harmonic excitations.
Synchronous Control of Master-slave Manipulator System under Deception Attacks

Field: Engineering (Physical Sciences)

In this paper, the synchronous control problem of the two-link master-slave manipulator system under deception attack is studied. For the communication channel is subjected to deception attack during the system control process, the sensors receive the wrong signal. The false data is injected into the controller, which affects the control effect of the system. It causes the system state to deviate from the control expectation. In order to solve this problem effectively, this paper adds a deception attack factor to the dynamics of the manipulator, and designs an adaptive law to estimate and compensate for the system model under attack. In the design of the manipulator synchronous control system, based on Lyapunov's stability control principle, a control law that can make the system closer to stability is designed. Finally, through MATLAB simulation, the synchronization control error of the manipulator approaches zero.
SIMULATION AND MODELING OF EVOKED RESPONSE ELECTROENCEPHALOGRAPH SIGNAL

Field: Neuroscience (Life Sciences)

Electroencephalograph (EEG) data for normal individuals with eyes-closed and under stimuli is analyzed. The stimuli consisted of photo, audio, motor and mental activity. We use several measures from nonlinear dynamics to analyze and characterize the data. We find that the dynamics of the EEG signal is deterministic and chaotic but it is not a low dimensional chaotic system. The evoked responses lead to a redistribution of strengths relative to eyes-closed data. Basically, strength in α waves decreases whereas that in β wave increases. We also carried out simulations separately and in combination for δ, θ, α and β waves to understand the data. From the simulation results, it appears that the characteristics of EEG data are consequences of filtering the data with a relatively small range of frequency (0.5–32 Hz). In view of this, we believe that calculation of known nonlinear measures is not likely to be very useful for studying the dynamics of EEG data. We have also successfully modeled the EEG time series using the concept of state space reconstruction in the framework of artificial neural network. It gives us confidence that one would be able to understand, in a more basic way, how collectivity in EEG signal arises.
Patterns of Student-Faculty Informal Interaction beyond the Classroom and Voluntary Freshman Attrition

Field: Social Sciences (Social Sciences)

In a test of Tinto's theoretical model of attrition, this study investigated the pattern of relationships between different types of student-faculty interaction beyond the classroom and college persistence during the freshman year. After controlling for student sex, academic aptitude and personality attributes, freshman persisters were found to have a significantly higher (p < .01) frequency of interactions along six dimensions than were voluntary leavers. Discriminant analysis indicated that student-faculty interactions focusing on discussion of intellectual or course related concerns contributed most to group discrimination.
Development of a micromirror based laster vector scanning automotive HUD

Field: Engineering (Physical Sciences)

Head-Up-Display (HUD) for automobiles is a system that displays the driving information such as the speed, fuel level, turning signal, GPS, etc on the windshield or on the road through a virtual image. With HUD, the driver does not need to lower his head to check the front panel for driving information and thus the driver can have a longer eyes-on-road time to improve the driving safety and comfort. LCD (Liquid Crystal Display) and VFD (Vacuum Fluorescent Display) based HUDs dominate today's automotive HUD market. In this thesis, a novel micromirror laser vector scanning HUD is developed for automobiles, which has the advantages over existing technologies including: 1) Higher brightness and contrast; 2) Wider angle of view; 3) Smaller size; and 4) Lower cost.
[Strategies of Histoplasma capsulatum for evading the cytocidal mechanisms of phagocytes].

Field: Immunology and Microbiology (Life Sciences)

Although proliferation of Histoplasma capsulatum within the macrophage is restricted by cell mediated immunity and, that there is no apparent deficiency in the fungicidal power of the macrophage, H. capsulatum can prosper in this intracellular microenvironment in some circumstances, which provides special nutritional advantages to intracellular growth for H. capsulatum, and access to other organs via the bloodstream and lymphatics. Nevertheless the environment within professional phagocytes is complex and generally hostile to microorganisms. Intracellular pathogens must avoid or overcome a series of obstacles in order to prevent their destruction. We present the strategies used by H. capsulatum to escape the host cell aggressiveness from the moment it reaches the cell surface up to its survival inside the phagocyte. Our aim is to discuss the advances on the escape mechanisms used by H. capsulatum to survive in the intracellular environment.
Safe handling of organic peroxides: An overview

Field: Chemical Engineering (Physical Sciences)

Abstract Organic peroxides are widely used today, and yet their properties and the procedures for their safe handling remain a mystery to many. After many years of hard work, the fog lifted considerably with the adoption, in 1986, of NFPA, 43B Code “Storage and Handling of Organic Peroxide Formulations [1] . A U.N. committee is also making a contribution by developing recommendations for the worldwide transport of organic peroxides [2] . This has had a secondary benefit in providing a forum for comparing and evaluating test methods and classifications worldwide. However, there is still much to be done.
Design of Robust Adaptive Beamforming Algorithms Based on Low-Rank and Cross-Correlation Techniques

Field: Computer Science (Physical Sciences)

This work presents cost-effective low-rank techniques for designing robust adaptive beamforming (RAB) algorithms. The proposed algorithms are based on the exploitation of the cross-correlation between the array observation data and the output of the beamformer. Firstly, we construct a general linear equation considered in large dimensions whose solution yields the steering vector mismatch. Then, we employ the idea of the full orthogonalization method (FOM), an orthogonal Krylov subspace based method, to iteratively estimate the steering vector mismatch in a reduced-dimensional subspace, resulting in the proposed orthogonal Krylov subspace projection mismatch estimation (OKSPME) method. We also devise adaptive algorithms based on stochastic gradient (SG) and conjugate gradient (CG) techniques to update the beamforming weights with low complexity and avoid any costly matrix inversion. The main advantages of the proposed low-rank and mismatch estimation techniques are their cost-effectiveness when dealing with high dimension subspaces or large sensor arrays. Simulations results show excellent performance in terms of the output signal-to-interference-plus-noise ratio (SINR) of the beamformer among all the compared RAB methods.
Use of brown sugar adhesive adhesive agents based on, palm and alobe extracts in the coating of crean bean seeds with rock dust

Field: Agricultural and Biological Sciences (Life Sciences)

Beans are extremely important for the Brazilian economy, are part of the diet, are very nutritious and have great commercial value, with high production due to their ability to adapt to different edaphoclimatic conditions. Traditional peoples produce seeds of local varieties, called creole seeds. They are resistant because they retain relevant characteristics left as an inheritance from their ancestors, who, free of charge, provided an environmental service for the preservation and perpetuation of this genetic heritage. Based on this, the objective of this work was to evaluate the effect of the adherent agents palm extract, aloe vera extract and sugar syrup in the pelleting of creole bean seeds (Minguita) with rock dust. The work was carried out in the Laboratory of Phytotechnics belonging to the Campus of Engineering and Agricultural Sciences of the Federal University of Alagoas. As adherent agents were used: water, palm extract, aloe vera extract and sugar solution. Rock dust (MB-4) was used for the coating. The evaluated parameters were: water content, weight of a thousand seeds, first germination count, germination, germination speed index, average germination time, germination uncertainty, length of root and aerial part and dry mass of seedlings. Palm is the most efficient adherent agent in the pelleting of bean seeds with rock dust, and can therefore be recommended for sustainable pelleting.
YY1-inudced activation of lncRNA DUXAP8 promotes proliferation and suppresses apoptosis of triple negative breast cancer cells through upregulating SAPCD2

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

Double homeobox A pseudogene 8 (DUXAP8) belongs to long non-coding RNAs (lncRNAs), which has been proven to promote the biological processes of multiple human cancers. Triple-negative breast cancer (TNBC) is the leading cause of cancer-related death in women worldwide. However, the specific role of lncRNA DUXAP8 and its underlying mechanism in TNBC remains to be unclear. We detected the expression of DUXAP8 in TNBC cells through qRT-PCR analysis. The effects of DUXAP8 silencing on TNBC cell proliferation and apoptosis were identified using CCK-8 assay, EdU assay, flow cytometry analysis and TUNEL assay. The downstream microRNA (miRNA) and messenger RNA (mRNA) of DUXAP8 were searched out through bioinformatics analysis and mechanism experiments. Rescue assays were conducted to verify the involvement of suppressor APC domain containing 2 (SAPCD2) in DUXAP8-mediated TNBC cell proliferation and apoptosis. DUXAP8 was highly expressed in TNBC cells compared to that in normal breast cells. Knockdown of DUXAP8 inhibited TNBC cell proliferation and accelerated cell apoptosis. DUXAP8 interacted with miR-29a-3p and thus enhanced the expression of SAPCD2. Moreover, YY1 transcription factor could bind to DUXAP8 promoter to activate the transcription of DUXAP8. YY1-induced transcriptional activation of DUXAP8 promotes TNBC cell growth through miR-29a-3p/SAPCD2 axis.
REED CANARY GRASS AND TASKS OF BREEDING NEW VARIETIES OF THIS CULTURE AT THE PRESENT STAGE

Field: Agricultural and Biological Sciences (Life Sciences)

Reed grass (reed canary grass) – Phalaris arundinacea L., is a perennial cereal grass that naturally lives in damp places, along the banks of reservoirs or in places with close groundwater. It is found both in Eurasia and on the American continent. In Russia, this species grows everywhere, with the exception of saline areas. The species is distinguished by very vigorous growth; in terms of protein content, dwarf grass is superior to meadow timothy and orchard grass, but with the age of the grass stand, the quality of food obtained from dwarf grass sharply decreases, and the palatability of the green mass also decreases.
Estimation and application of latent variable models in categorical data analysis

Field: Decision Sciences (Social Sciences)

Bartholomew (1980, 1984 a ) has laid down a foundation for factor analysis based on latent variable models. Shea (1984, 1985) has provided computer programs for estimating one‐factor latent variable models when responses are binary or polytomous variables. However, the programs have limitations on number of variables and the sample size, which limits their applicability, especially when variables are polytomous. However, the more important limitation is that it is not possible to use two‐factor models when one‐factor models are not adequate. Here, we have gone further and successfully obtained maximum likelihood estimates for both the one‐factor and two‐factor latent variable models for binary and polytomous variables. The new algorithm is much faster because of careful and efficient programming. More importantly, generalization to high latent domensions is straightforward. Formal hypothesis testing is very difficult when variables are very large in number. However, we have shown in our examples that some interesting graphical interpretations can be made.
Synthesis of nanocages for application as nano-size reactors/containers

Field: Materials Science (Physical Sciences)

Self-assembly of block copolymers (BCPs) have recently received much attention because of its ability to form microdomains that are tens of nanometers. Modified block copolymer has proved to be a promising way of preparing nanoparticles, as the chemistry of the various blocks can be made use to form domains of a variety of shape and size. In this study block copolymer polystyrene-b-poly(4-vinylpyridine) (PS-P4VP) were synthesized by anionic polymerization and characterized using DSC, FTIR, NMR, SEC. Its self-assembled morphology was investigated using TEM and AFM. We have for the first time synthesized polystyrene-b-poly(4-vinylpyridine) (PS-P4VP) betaine copolymers using PS-P4VP copolymer as a precursor. Solution properties studies and morphology investigations confirmed that the sultone-induced micellization led to the formation of ribbon shape nanostructures. It was also found that a core-corona inversion can be induced in-situ with water for PS-P4VP-sultone. The morphology of the micellar film can be tuned from hexagonal array of dots to ribbon-like by annealing or solvent treatment. Both annealing and solvent treatment add a facile yet effective tool for controlling pattern formation. Gold nanoparticles, titania nanoparticles and Au-Ag alloy nanoparticles were synthesized in PS-P4VP micelle or PS-P4VP-sultone micelle by in-situ reduction. This procedure gives rise to monodisperse nanoparticles. The use of gold-polymer film as a memory device is also illustrated.
A Cultural Imperialistic Homecoming: The Korean Wave Reaches the United States

Field: Arts and Humanities (Social Sciences)

Despite the assumption that Americans do not consume foreign media,1 South Korean2 popular culture is a growing phenomenon in the United States. Since Hallyu, meaning the Korean Wave and referring to the international success of Korean films, pop music, television dramas, and other cultural products, swept across Asia in the 1990s,3 the Korean government and culture industries have embarked on a quest to introduce Korean media worldwide to promote Korea and Korean products.4 Subsequently, after decades of alleged US cultural imperialism during which media flowed in a one-way direction from the United States to Korea, there is now a contra-flow of Korean media entering the United States.5 Interestingly, in recent years, originals and remakes of Korean films have been shown in mainstream US theaters, and Korean pop songs have appeared on US music charts.6 Long before Hallyu, The Beatles led the British Invasion of popular culture into the United States in the 1960s7, and in the 1990s, the Japanese anime series, Pokémon, was labeled a "craze" by CNN.8 Each cultural phenomenon has its own story of how it developed and how it was able to gain popularity, but this chapter shares the unique tale of Hallyu's passage into the United States.KeywordsMusic VideoFilm IndustryCultural ImperialismKorean CommunityKorean MediumThese keywords were added by machine and not by the authors.

Correlation analysis of gene and immune microenvironment for 87 melanoma cases.

Field: Medicine (Health Sciences)

e21555 Background: To map the genome of Chinese melanoma patients and explore its correlation with the expression of tumor immune microenvironmental indicators. Methods: Next generation sequencing was performed on 87 cases of primary melanoma that had been surgically removed from Nanjing Drum Tower Hospital from July 2010 to May 2017. Immunohistochemistry was carried out to detect the expressions of PD1, PDL1, CD3+TIL, MSH2, MSH6, PMS2 and MLH1. Results: BRAF mutations were the most common (26.4%), followed by KIT mutations (12.6%) in melanoma patients. RB1 gene copy number deletion (55%) and CDK4 (25%)/CCND1 (22.5%) gene copy number amplification were also common. The prognosis of patients could be distinguished by grouping the expression of PDL1 and TIL, and the difference may be related to the expression of PD1. There were more copy number amplication of genes with poor prognosis in PDL1-TIL- patients. Conclusions: The classification of tumors into four microenvironmental subtypes based on PDL1 and TIL expression is an appropriate method to stratify patients with different clinical outcomes. At the genetic level, there are more copy number amplification of the genes with poor prognosis in patients with TIL-PDL1- type, so the prognosis is always worse than that of patients with TIL+PDL1+ type. Gene may affect the prognosis of patients by affecting the tumor immune microenvironment.
Implementing the REPAIRER Human Factors Safety Reporting System Through MRM(MxHF) to Meet SMS Compliance in Aviation Maintenance

Field: Engineering (Physical Sciences)

Reiterating the importance of having a human factor related safety reporting system for aviation maintenance to reduce human error and utilizing it to gain SMS compliance, the REPAIRER method of identifying and reporting human factors hazards in aviation maintenance is reintroduced. How and why the REPAIRER method system is of such importance in the implementation of aviation maintenance safety programs can be linked to the success and evolution of maintenance resource management and human factors programs which have been effective in reducing human error in aviation maintenance. These programs are rooted in effective communication methods, as well as the identification of human factor elements. To illustrate this point, the successes of maintenance resource management are discussed. Additionally, the incredible strides that the Federal Aviation Administration (FAA) has taken to propel a human factorscentered safety program in aviation maintenance are brought to light with the FAA’s latest transition of MRM (Maintenance Resource Management) to MxHF (Maintenance Human Factors). This newly appointed program, which replaced a decades old FAA MRM program, highlights the significant changes in MRM, notably the emphasis on human factors. Given the significant shift from MRM to MxHF, the authors explore the implementation of the REPAIRER aviation maintenance reporting system under the new guidelines and demonstrate how it could fulfill many of the desired outcomes of both programs, while still gaining SMS compliance.
Multilingualism in Language Classes for Refugees in Luxembourg: Second Language Teaching or Repertoire Building?

Field: Social Sciences (Social Sciences)

Official trilingualism is often drawn upon to portray Luxembourg as a heterogeneous society with high levels of linguistic capital, where multilingualism is declared to be an asset both at individual and societal level. With the increased number and shifted geographic origin of migrants from refugee backgrounds new questions surface concerning the linguistic integration of these new arrivals, who are often incorrectly associated with zerolingualism and whose language capital is seldom perceived as a valuable asset. It has been argued that in contexts of forced migration one cannot talk of second or foreign language learning: migrants are not acquiring the language(s) of the mainstream society for the mere reason of approximating native speakers’ performances; these languages form part of their everyday lived experiences, hence they have to appropriate features that best suit their needs. Accordingly, their full linguistic repertoires constitute single integrated continua that include all the language resources they have learned and accumulated. In line with this and contesting the idea of zerolingualism, we maintain that through a wide variety of trajectories ranging from comprehensive learning to informal encounters with languages, migrants from refugee backgrounds have developed partial, truncated competences in several languages that have resulted in complex linguistic repertoires. Our contribution aims at investigating whether the recognition of multilingualism in Luxembourg entails the acknowledgment of the refugees’ full linguistic repertoires, or on the contrary, it remains limited to the appreciation of official trilingualism and proficiency in standard English. In our analysis we are going to rely on data collected in the context of a French language course for beginners, which is offered to newly arrived migrants by volunteer teachers. Besides commenting on the presence (or absence) of multilingual approaches, we seek to explore whether migrant language features are acknowledged as useful resources and how, if at all, the class draws on the fluid use of all the languages present for both learning and functional purposes. On this note, we aim to determine what is more prominent in this context: the monoglossic perspective where languages are conceived in a linear and compartmentalised way or a repertoire-building approach based on awareness and positive attitudes towards teachers’ and learners’ multilingual repertoires.
