On the performance of GFEM with trigonometric enrichment in bidimensional dynamic elastoplastic modelling
Year: 2019

In this work, an investigation is carried out concerning the performance of proposed enriched quadrilateral C0 element, developed by Generalized Finite Element Method, in dynamic elastoplastic models. The enriched quadrilateral C0 element is formulated by considering conventional shape function as global PU basis and trigonometric functions as the local basis. The enriched mesh distortion sensitivity is investigated in an elastodynamic problem. Other numerical aspects are also investigated in several benchmark analyses, involving stress concentration effect. The condition numbers of the stiffness and the consistent mass matrices are calculated for each enrichment level in different situations, and the error in norm L2 is calculated for displacement and stress. The results are compared with other numerical formulations encountered in the literature. Several numerical aspects of enriched quadrilateral C0 element formulated by GFEM are discussed and observed in the applications, and it performs competitiveness in comparison to other numerical formulations.

Landsat's past paves the way for data democratization in earth science
Year: 2020

The Landsat Program has been observing and collecting Earth system data from space since 1972. Over this time, advances in spatial, spectral, and radiometric resolution have allowed the Landsat satellites to evolve into powerful global Earth observation imaging systems. The longevity of the Landsat Program has produced a massive catalogue of imagery data. The sheer magnitude of this collection necessitates the use of scalable techniques to extract value from decades of remote sensing data. With the introduction of commercial cloud computing, it is now possible to cheaply provision resources for processing and storing enormous amounts of such data. Machine learning based computer vision is advancing at a blistering pace and has shown great promise when applied to satellite imagery. The combination of cloud computing and machine learning offers the ability to analyze the decades of imagery collected by the Landsat Program at a cost never before possible. The focus of this chapter is to discuss the Landsat Program progression, cloud computing, machine learning, and data policy and how all these components contribute to greater understanding on the state of our planet Earth.
Prevention of Pseudomonas aeruginosa Biofilm Formation on Soft Contact Lenses by Allium sativum Fermented Extract (BGE) and Cannabinol Oil Extract (CBD)
Venue: Antibiotics
Year: 2019

Two natural mixtures, Allium sativum fermented extract (BGE) and cannabinol oil extract (CBD) were assessed for their ability to inhibit and remove Pseudomonas aeruginosa biofilms on soft contact lenses in comparison to a multipurpose Soft Contact Lens care solution present on the Italian market. Pseudomonas aeruginosa (ATCC 9027 strain) and Pseudomonas aeruginosa clinical strains isolated from ocular swabs were tested. Quantification of the biofilm was done using the microtiter plate assay and the fractional inhibitory concentration index was calculated. Both forms of Pseudomonas aeruginosa generated biofilms. BGE at minimal inhibitory concentration (MIC) showed inhibition percentages higher than 55% for both strains, and CBD inhibited biofilm formation by about 70% The care solution at MIC inhibited biofilm formation by about 50% for both strains tested. The effect of BGE on the eradication of the microbial biofilm on soft contact lenses at MIC was 45% eradication for P. aeruginosa ATCC 9027 and 36% for P. aeruginosa clinical strain. For CBD, we observed 24% biofilm eradication for both strains. For the care solution, the eradication MICs were 43% eradication for P. aeruginosa ATCC 9027 and 41% for P. aeruginosa clinical strain. It was observed that both the test soft contact lenses solution/BGE (fractional inhibitory concentration index: 0.450) and the test soft contact lenses solution/CBD (fractional inhibitory concentration index: 0.153) combinations exhibited synergistic antibiofilm activity against most of the studied bacteria. The study showed that BGE and CBD have good effect on inhibition of biofilm formation and removal of preformed biofilms, which makes them promising agents that could be exploited to develop more effective care solutions.
Wideband Cavity Backed Spiral Antenna Design and Mutual Coupling Study in A Closely Spaced Array
Venue: 2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM)
Year: 2018

This paper deals, first, with the design of a 6 to 18GHz Cavity Backed Archimedean Spiral Antenna (CB ASA) whose performance, in terms of VSWR, gain, and axial ratio, was improved by utilizing multiple absorbing materials. Then, by placing two spiral elements side by side, the mutual coupling effect was investigated in a two element CB ASA array, in which one element was excited while the other was passive with a matched load. The results show little effect on the performance of the active element due to the mutual coupling with the adjacent element, with less than 3dB axial ratio, less than 2 dB VSWR and consistent radiation pattern.
Gastric ulcer healing effect of wild honey and its combination with Turmeric (Curcuma domestica Val. Rhizome on male Wistar rats
Year: 2014

Gastric ulcer is a common disorder in human at any ages. In this research, the antiulcer activity of wild honey produced by Apis dorsata, alone or in combination with Turmeric Rhizome, was evaluated in healing acute gastric ulcer. Male Wistar albino rats(150 250 g) were induced ulcers with aspirin at 405 mg/kg BW and ethanol. Antiulcer evaluation was done based on the gastric acidity, numbers and diameter of ulcers, ulcer index, healing ratio, histological examinations, and body weight. The results showed that the groups given honey alone, turmeric alone, and combination of turmeric honey displayed significant ulcer healing compared to the control group. Ulcers in the group administered with combination of turmeric wild honey was different significantly from the turmeric alone and wild honey alone groups with increased body weight in that group. The result showed that wild honey(2125 mg/kg BW) had the greatest activity in healing ulcers among other groups. The combination of turmeric wild honey had a good activity in healing ulcers and increased the body weight of the group.
Recent changes in immigration policy and U.S. naturalization patterns
Year: 2020

Naturalization bestows economic benefits to immigrants, their families, and communities through greater access to employment opportunities, higher earnings, and homeownership. It is the cornerstone of immigrant assimilation in the United States. Yet, less than 720,000 of the estimated 8.5 million legal permanent residents (LPRs) eligible to naturalize do so on a yearly basis. Using data from the 2008 2018 American Community Survey, we analyze how the expansion of interior immigration enforcement impacts the decision to naturalize. We find that the adoption over an entire year of one enforcement initiative, or of two enforcement initiatives for half a year, raises the naturalization hazard by 2 percent. The effect is more pronounced among LPRs who are Mexican, women, or reside in non mixed status households. Finally, the impact is driven by police based, as opposed to employment based, interior immigration enforcement. In sum, immigrants who naturalize in response to intensified enforcement may be doing so out of fear or uncertainty about their ability to secure their citizenship status and rights in a rapidly changing immigration policy environment increasingly hostile towards immigrants.
Effects of Organic Acid Supplemented Diets on Growth Performance, Egg Production and Quality and on Serum Parameters in Laying Hens
Year: 2006

La presente etude a ete conduite afin de determiner les effets d'une supplementation alimentaire en acides organiques (0.5, 1.0 et 1.5% sur les performances zootechniques (croissance, consommation et efficacite de la ration, production en oeufs) les qualites des oeufs et sur les parametres seriques des poules pondeuses. Au total, 180 poules pondeuses blanches Lohman LSL agees de 20 semaines ont ete reparties en 4 groupes de 45 animaux. Les poules ont recu une ration (caracterisee par 17% de proteines brutes et 2800 kcal/kg en energie metabolisable) supplementee par 0% (groupe controle) 0.5% (groupe I) 1.0% (groupe II) et 1.5% (groupe III) d'un melange d'acides organiques (acides formique et propionique et sels ammoniaques correspondants) pendant 18 semaines. Le traitement en acides organiques de la ration n'a pas affecte de facon significative les parametres de croissance (poids vif et quantite de l'ingere) mais il a ameliore notablement la production en oeufs en accelerant la capacite de ponte chez les poules de 24 a 28 semaines et en prolongeant la periode de ponte des poules de 36 et 38 semaines, ainsi que l'efficacite alimentaire a un moindre degre. La proteinemie, l'albuminemie et l'activite serique de l'AST ont ete significativement augmentees alors que les autres parametres seriques testes (activite de l'ALT, cholesterolemie, triglyceridemie, lipidemie totale et concentrations en HDL et LDL) n'ont pas varie. L'ensemble de ces resultats montre qu'une supplementation de la ration en acides organiques peut etre envisagee chez la poule pondeuse afin d'ameliorer la production en oeufs et l'efficacite du metabolisme protidique.
Formal Theory of Creativity, Fun, and Intrinsic Motivation (1990 2010)
Venue: IEEE Transactions on Autonomous Mental Development
Year: 2010

The simple, but general formal theory of fun and intrinsic motivation and creativity (1990 2010) is based on the concept of maximizing intrinsic reward for the active creation or discovery of novel, surprising patterns allowing for improved prediction or data compression. It generalizes the traditional field of active learning, and is related to old, but less formal ideas in aesthetics theory and developmental psychology. It has been argued that the theory explains many essential aspects of intelligence including autonomous development, science, art, music, and humor. This overview first describes theoretically optimal (but not necessarily practical) ways of implementing the basic computational principles on exploratory, intrinsically motivated agents or robots, encouraging them to provoke event sequences exhibiting previously unknown, but learnable algorithmic regularities. Emphasis is put on the importance of limited computational resources for online prediction and compression. Discrete and continuous time formulations are given. Previous practical, but nonoptimal implementations (1991, 1995, and 1997 2002) are reviewed, as well as several recent variants by others (2005 2010) A simplified typology addresses current confusion concerning the precise nature of intrinsic motivation.
GEOMETRIC MODELS FOR LATERITIC SOIL STABILIZED WITH CEMENT AND BAGASSE ASH
Year: 2016

Agricultural and environmental demands for natural aggregates coupled with frequent increases in the price of cement and other binders have consequently escalated the cost of construction, rehabilitation and maintenance of road works. Soil stabilization emerges as an attractive option for providing low cost roads. Bagasse ash is an agricultural material obtained after squeezing out the sweet juice in sugarcane and incinerating the fibrous residue to ash. This residue that would have constituted an environmental problem during disposal and handling could be used as a supplement or partial replacement for cement in the cement bound soil when converted to ash. Thus this study attempted to investigate into the effects of bagasse ash on compaction and strength characteristics of cement stabilized lateritic soil and also to develop geometric models. The compaction, California bearing ratio, unconfined compressive strength and durability tests were carried out on the cement stabilized soil. Constant cement contents of 2% 4% 6% and 8% with variations of bagasse ash from 0% to 20% at 2% intervals and all percentages used were by the weight of dry soil. The multiple regression and the least square approach was used to develop geometric equations which was made less rigorous with Minitab statistical software. The three geometric equations developed covered the relationships of cost of bagasse ash content, optimum moisture content, cement content, California bearing ratio and unconfined compressive strength at 7 days. It was observed that optimum moisture content increased progressively while maximum dry density reduced with increase in bagasse ash content. Also the increase in cement content increased both the optimum moisture content and maximum dry density. In addition, all the strength properties were increased with increase in bagasse ash content and chemistry responsible was also presented. Thus bagasse ash was confirmed to be a good admixture in soil stabilization for road work. The models were calibrated and verified; and were found to be dependable. http:/dx.doi.org/10.4314/njt.v35i4.11
Assisted lipid deposition by reductive electrochemical aryldiazonium grafting and insertion of the antiport NhaA protein in this stable biomimetic membrane.
Venue: Colloids and surfaces. B, Biointerfaces
Year: 2020

Quartz crystal microbalance studies have been carried out to monitor the fusion of lipid vesicles (pure 1,2 dimyristoyl sn glycero 3 phosphocholine, DMPC) and mixed vesicles (DMPC and 4 decylaniline) In order to increase the stability of the lipid deposits onto the electrodes, we have developed an original approach involving electrografting of adsorbed mixed vesicles. Aryldiazonium salts generated in situ from 4 decylaniline (4DA) present in adsorbed and fused mixed vesicles at the electrode surface allow their cathodic reduction and subsequent grafting. The stability of the supported lipid deposit has been shown to significantly increase from less than one day for pure DMPC to about two weeks with the lipid deposition assisted by electrochemical grafting. In this stable lipid deposit, the insertion of the sodium/proton antiporter membrane protein (NhaA) or its inactive mutant has been carried out by fusion of proteoliposomes. This has been followed by characterization of the inserted protein activity by cyclic voltammetry onto an electrode previously modified by an adsorbed pH sensor (2 anthraquinone sulfonate) Activation of the protein function by sodium ions leads to a shift of the interfacial pH and confirms the integrity of the immobilized NhaA.
Rethinking Token Mixing MLP for MLP based Vision Backbone
Venue: ArXiv
Year: 2021

In the past decade, we have witnessed rapid progress in the machine vision backbone. By introducing the inductive bias from the image processing, convolution neural network (CNN) has achieved excellent performance in numerous computer vision tasks and has been established as de facto backbone. In recent years, inspired by the great success achieved by Transformer in NLP tasks, vision Transformer models emerge. Using much less inductive bias, they have achieved promising performance in computer vision tasks compared with their CNN counterparts. More recently, researchers investigate using the pure MLP architecture to build the vision backbone to further reduce the inductive bias, achieving good performance. The pure MLP backbone is built upon channel mixing MLPs to fuse the channels and token mixing MLPs for communications between patches. In this paper, we re think the design of the token mixing MLP. We discover that token mixing MLPs in existing MLP based backbones are spatial specific, and thus it is sensitive to spatial translation. Meanwhile, the channel agnostic property of the existing token mixing MLPs limits their capability in mixing tokens. To overcome those limitations, we propose an improved structure termed as Circulant Channel Specific (CCS) token mixing MLP, which is spatialinvariant and channel specific. It takes fewer parameters but achieves higher classification accuracy on ImageNet1K benchmark.
Relegated to chronic poverty: financial difficulties faced by people with mental illness in the United States
Year: 2018

This article is about the financial difficulties faced by people living in the United States who are poor and have mental illness, and a pilot programme seeking to help them. Millions of people in the United States cannot afford to meet their basic needs, and levels of unsustainable debt are high, given low incomes and a relatively high cost of living. People with mental illness are disproportionately represented among this group, even those who receive financial assistance from the government. The pilot project focused on helping people understand and make the best use of financial services, and worked with local banks and the government to try to improve locally available financial services. The United States has a great deal to learn from the experience of global microfinance. In addition, the benefits system must be reformed to increase people's incomes, and reduce disincentives to saving and finding employment.

Identification of milling process damping using operational modal analysis
Year: 2017

This paper provides a novel approach for identifying the process damping directly from chatter free milling tests. First, power spectrum density matrix of cutter's deflections is theoretically derived by introducing transfer function and random excitation force, and the spectral decomposition of the power spectrum density matrix is formulated as an explicit function of modal parameters. Then, exponential attenuation method is adopted to extract the damping ratios from the inverse Fourier transformation result of the decomposed form. Finally, tangential and radial ploughing force coefficients, which are utilized to characterize process damping, are simultaneously calculated based on energy balance principle. Besides, experimental setup consisting of displacement sensors is specially designed to measure the cutter's deflections, which are further used to calculate the power spectrum density required in the above identification procedure. It is experimentally proven that the accuracy of chatter stability limits in milling process is improved when the proposed process damping model is considered.
Reliable and Modeling Attack Resistant Authentication of Arbiter PUF in FPGA Implementation With Trinary Quadruple Response
Venue: IEEE Transactions on Information Forensics and Security
Year: 2019

Field programmable gate array (FPGA) is a potential hotbed for malicious and counterfeit hardware infiltration. Arbiter based physical unclonable function (A PUF) has been widely regarded as a suitable lightweight security primitive for FPGA bitstream encryption and device authentication. Unfortunately, the metastability of flip flop gives rise to poor A PUF reliability in FPGA implementation. Its linear additive path delays are also vulnerable to modeling attacks. Most reliability enhancement techniques tend to increase the response predictability and ease machine learning attacks. This paper presents a robust device authentication method based on the FPGA implementation of a reliability enhanced A PUF with trinary digit (trit) quadruple responses. A two flip flop arbiter is used to produce a trit for metastability detection. By considering the ordered responses to all four combinations of first and last challenge bits, each quadruple response can be compressed into a quadbit that represents one of the five classes of trit quadruple response with greater reproducibility. This challenge response quadruple classification not only greatly reduces the burden of error correction at the device but also enables a precise A PUF model to be built at the server without having to store the complete challenge response pair (CRP) set for authentication. Besides, the real challenge to the A PUF is generated internally by a lossy, nonlinear, and irreversible maximum length signature generator at both the server and device sides to prevent the naked CRP from being machine learned by the attacker. The A PUF with short repetition code of length five has been tested to achieve a reliability of 1.0 over the full operating temperature range of the target FPGA board with lower hardware resource utilization than other modeling attack resilient strong PUFs. The proposed authentication protocol has also been experimentally evaluated to be practically secure against various machine learning attacks including evolutionary strategy covariance matrix adaptation.
