Investigating parameters participating in the infant respiratory control system attractor
Venue: 2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society
Year: 2008

Theoretically, any participating parameter in a non linear system represents the dynamics of the whole system. Taken's time delay embedding theory provides the fundamental basis for allowing non linear analysis to be performed on physiological, time series data. In practice, only one measurable parameter is required to be measured to convey an accurate representation of the system dynamics. In this paper, the infant respiratory control system is represented using three variables a digitally sampled respiratory inductive plethysmography waveform, and the derived parameters tidal volume and inter breath interval time series data. For 14 healthy infants, these data streams were analysed using recurrence plot analysis across one night of sleep. The measured attractor size of these variables followed the same qualitative trends across the nights study. Results suggest that the attractor size measures of the derived IBI and tidal volume are representative surrogates for the raw respiratory waveform. The extent to which the relative attractor sizes of IBI and tidal volume remain constant through changing sleep state could potentially be used to quantify pathology, or maturation of breathing control.
Proximal events in Wnt signal transduction
Venue: Nature Reviews Molecular Cell Biology
Year: 2009

The Wnt family of secreted ligands act through many receptors to stimulate distinct intracellular signalling pathways in embryonic development, in adults and in disease processes. Binding of Wnt to the Frizzled family of receptors and to low density lipoprotein receptor related protein 5 (LRP5) or LRP6 co receptors stimulates the intracellular Wnt b catenin signalling pathway, which regulates b catenin stability and context dependent transcription. This signalling pathway controls many processes, such as cell fate determination, cell proliferation and self renewal of stem and progenitor cells. Intriguingly, the transmembrane receptor Tyr kinases Ror2 and Ryk, as well as Frizzled receptors that act independently of LRP5 or LRP6, function as receptors for Wnt and activate b catenin independent pathways. This leads to changes in cell movement and polarity and to the antagonism of the b catenin pathway.
How Do Leverage Ratios Affect Bank Share Performance During Financial Crises: The Japanese Experience of the Late 1990s
Year: 2011

This study investigates the relationship between leverage ratios and bank share performance for a sample of Japanese banks during the period of financial crisis in the late 1990s. We differentiate between two types of leverage ratios: book leverage and market leverage. We show that market leverage instead of book leverage observed before the crisis has statistically and economically significant predictive power for the cross sectional variation in bank performance during the crisis, even after controlling for a variety of other indicators reflecting bank's characteristics and financial conditions. We also find that banks with lower market leverage ratios were affected more adversely by the failure announcements of large financial institutions during the crisis. The results are robust across alternative model specifications, statistical methodologies, lengths of sample intervals, and measures of bank share performance during the crisis. Our results therefore have important implications for regulators in identifying distressed banks that are vulnerable to the deterioration in conditions of the financial system.
Creation of Ion Selective Membranes from Polyethylene Terephthalate Films Irradiated with Heavy Ions: Critical Parameters of the Process
Venue: Membranes and Membrane Technologies
Year: 2020

A combination of a long exposure to ultraviolet (UV) radiation and the extraction of radiolysis and photolysis products from tracks makes it possible to create ion selective membranes from polyethylene terephthalate (PET) films irradiated with heavy ions. These membranes exhibit high selectivity for singly charged cations and high transport characteristics in the electrodialysis mode. The aim of this study is to analyze the mechanisms of the transformation of latent tracks into a system of through pores of the subnanometer range in more detail. Polyethylene terephthalate films are irradiated with accelerated Xe and Bi ions with energy losses in the polymer of 11 and 18 keV/nm, respectively. The evolution of the free volume and the accumulation of carboxyl groups in the irradiated films at different stages of the treatment are studied using gravimetry, IR and UV spectroscopy, conductometry, and electron microscopy methods. It is found that the properties of the resulting membranes depend on several critical parameters, which include, in addition to temperature during extraction, the energy loss of the bombarding ion, the pH of the solution used for extraction, and ion fluence. Dramatic changes in the membrane properties are observed at ion fluences at which individual tracks begin to overlap.
Combining augmented reality with real maps to promote social interaction in treasure hunts
Venue: CoSECivi
Year: 2017

The game "Enigma Galdiano" is a mobile game that implements a treasure hunt in the Lazaro Galdiano museum in Madrid (Spain) The main design challenge in this game is to promote and facilitate the collaboration between an adult and a kid playing the game together. The collaboration is mediated through a map, a real one, that is used by the adult and contains additional information that is not included in the app. In this paper we describe the game along with the results of an empirical evaluation that suggest a few lines of improvement.
Central Bank Digital Currency: When Price and Bank Stability Collide
Year: 2020

An account based central bank digital currency has the potential to replace demand deposits in private banks. In that case, the central bank invests in the real economy and takes over the role of maturity transformation to allow risk sharing among depositors. Her function as intermediary exposes the CB to demand liquidity or 'spending' shocks by her depositors. Since demand deposit contracts are nominal, high aggregate spending not necessarily demands excessive liquidation of real investment by the central bank. A run on a central bank can, therefore, manifest itself either as a standard run characterized by excessive real asset liquidation (rationing) or as a run on the price level where a small supply of real goods meets a high demand. The central bank thus trades off price stability against the excessive liquidation of real goods.
Modeling carbon regulation policies in inventory decisions of a multi stage green supply chain: A game theory approach
Venue: Comput. Ind. Eng.
Year: 2019

Governments and policymakers around the world put their best efforts to control the pollutions and climate change. Thus, they set various regulations to reduce greenhouse gases and carbon footprints. It is expected that firms should follow these regulations while maintaining their profitability. In this regard, firms can manage their carbon emissions across their supply chain (SC) by inventory management, since operational adjustments may affect the amount of carbon emissions, such as changing the production quantity and the frequency of transportations. This study applies a Stackelberg game between the government and a multi stage green supply chain (GSC) in which the government's goal is to maximize social welfare and that of the GSC is to minimize its cost. First, we formulate the inventory cost and carbon emission of a multi stage GSC under two decision making structures: non coordinated and coordinated GSCs. Second, we develop eight bi level mathematical programming models considering the structure of the GSC and the regulations of the government including carbon cap, carbon tax, carbon trade, and carbon offset. Then two solution approaches will present for solving problems based on the type of the GSC structure. This study examines the effect of coordination and carbon regulations on inventory cost, carbon emission and the objective function of the government.
An Empirical Study of Stress and Stress Management among Faculties of Private Technical Institutions in Meerut District
Year: 2017

Stress is often described as a silent killer because the effect of stress is not readily apparent and it is observed that high level of stress is found at workplace. Job is part and parcel of life. Stresses on the job affect the efficacy and efficiency of a person. Hence, if one is not satisfied with his/her job the quality of life is adversely affected. Earlier teaching profession was recognized low stress occupation as they had light workload, minimum working hours and smart perks such as participation in conference and seminar. Some recent studies concluded that the degree of stress among the faculty in private technical institutions is quite high because most of people in this profession experience some kind of frustration, tension and anxieties related to the job assigned to them in addition to their underpaid job as compared to the government institutions. The present study was conducted to assess the level and sources of stress among the faculties in private technical institution and find out the impact of the stress on the performance and health of the Original Research Article Shabana et al.  2017; Article no.JEMT.36123 2 faculties. The questionnaire based on five point likert scale was used to extract the information. Private Institutes should provide adequate workload, clean and safer working environment. They should also arrange yoga camp, meditation camp, aerobics, entertaining programs etc. for the alleviation of the job stress among faculty.

Impact of Fishmeal Replacement in Diets for Gilthead Sea Bream (Sparus aurata) on the Gastrointestinal Microbiota Determined by Pyrosequencing the 16S rRNA Gene
Venue: PloS one
Year: 2015

Recent studies have demonstrated the impact of diet on microbiota composition, but the essential need for the optimization of production rates and costs forces farms and aquaculture production to carry out continuous dietary tests. In order to understand the effect of total fishmeal replacement by vegetable based feed in the sea bream (Sparus aurata) the microbial composition of the stomach, foregut, midgut and hindgut was analysed using high throughput 16S rDNA sequencing, also considering parameters of growth, survival and nutrient utilisation indices.A total of 91,539 16S rRNA filtered sequences were analysed, with an average number of 3661.56 taxonomically assigned, high quality sequences per sample. The dominant phyla throughout the whole gastrointestinal tract were Actinobacteria, Protebacteria and Firmicutes. A lower diversity in the stomach in comparison to the other intestinal sections was observed. The microbial composition of the Recirculating Aquaculture System was totally different to that of the sea bream gastrointestinal tract. Total fishmeal replacement had an important impact on microbial profiles but not on diversity. Streptococcus (p value: 0.043) and Photobacterium (p value: 0.025) were highly represented in fish fed with fishmeal and vegetable meal diets, respectively. In the stomach samples with the vegetable diet, reads of chloroplasts and mitochondria from vegetable dietary ingredients were rather abundant. Principal Coordinate Analysis showed a clear differentiation between diets in the microbiota present in the gut, supporting the presence of specific bacterial consortia associated with the diet.Although differences in growth and nutritive parameters were not observed, a negative effect of the vegetable diet on the survival rate was determined. Further studies are required to shed more light on the relationship between the immune system and sea bream gastrointestinal tract microbiota and should consider the modulation of the microbiota to improve the survival rate and nutritive efficacy when using plant based diets.
Palm region extraction for contactless palmprint recognition
Venue: 2015 International Conference on Biometrics (ICB)
Year: 2015

Palm region extraction is one of the most important processes in palmprint recognition, since the accuracy of extracted palm regions has a significant impact on recognition performance. Especially in contactless recognition systems, a palm region has to be extracted from a palm image by taking into consideration a variety of hand poses. Most conventional methods of palm region extraction assume that all the fingers are spread and a palm faces to a camera. This assumption forces users to locate his/her hand with limited pose and position, resulting in impairing the flexibility of the contactless palmprint recognition system. Addressing the above problem, this paper proposes a novel palm region extraction method robust against hand pose. Through a set of experiments using our databases which contains palm images with different hand pose and the public database, we demonstrate that the proposed method exhibits efficient performance compared with conventional methods.

Understanding of the theory can assist organizations in improving their human capital capabilities.
Theoretical Foundations for Human Rights
Year: 2018

This article explores an alternative to the established dichotomy between philosophical (natural law) accounts of human rights, characterized by a foundationalist tendency, and political (practice based) accounts of human rights, which aspire to be non foundationalist. I argue that in order to justify human rights practice, political accounts of human rights cannot do without the support of theoretical foundations, although not necessarily of the natural law variety. As an alternative to natural law metaphysics, a deflationary theory of human rights, based on a deflationary account of truth, is put forward. Starting from a distinction between 'extreme' and 'moderate' forms of deflationism, this article defends a constructivist theory of human rights grounded on the Humean notion of conventionalism. This innovative approach to human rights provides political conceptions of human rights with the foundations (or quasi foundations) they need, but are currently lacking.
Palm Oil Biomass Waste a Renewable Energy Resource for Power Generation
Year: 2019

This work evaluated the palm oil biomass waste as a source of renewable energy for electric power generation. Nigeria was once the largest producer of Oil Palm products, but since has been relegated to the back ground by Malaysia and some other countries and needs to revitalize its palm oil industries. Electricity regeneration in Nigeria has also been highly politicized and still at shortfall to its teeming population demand. This situation invariably requires revamping through exploitations of alternative energy sources. This work was carried out at Presco Nigeria Ltd which owns palm plantations from where we obtained our oil palm empty fruit bunches for this research. The result obtained from this work shows that 896 kg of empty fruit bunches produced 1.7 MW of power though lower than that of the same mass of methane, it is proving to be by far more cost effective, easier to maintain and run. The research also reported that oil palm empty fruit bunch has more calorific value than other oil palm biomass resources. Placing this research finding with others in literature indicates that the quantity of the biomass is directly proportional to the amount of energy produced.
"To Be a Man" Progressive Masculinities in Lorraine Hansberry's Cold War Civil Rights Plays
Year: 2019

This chapter reinterprets the most well known civil rights play, A Raisin in the Sun (1959) arguing that playwright Lorraine Hansberry situates the fight for civil rights firmly within black left feminist politics. In her characterization of Walter Lee in Raisin and his later analog in the posthumous Les Blancs (1970) Hansberry challenges prevailing assumptions about black masculinity. By analyzing the scripts and production histories of these plays, along with Hansberry's essays in The Village Voice, Burrell demonstrates how Hansberry opposed stereotypes propounded by white liberals like Norman Mailer, who cast black men as violent and hypersexual. Ultimately, Hansberry transformed enactments of black masculinity on the American stage, creating a space for progressive black masculinities.
Role of pulses in the food and nutritional security in India
Year: 2013

In spite of impressive growth of Indian agriculture, ensuring household food and nutritional security is still a challenge due to imbalanced growth in agriculture biased towards wheat and rice. Though production of pulses in the recent decade has increased but is not in pace with the increase in population. Pulses for being a major source of protein in Indian diet and for being resource conserving and environmental friendly, the increase in pulse production will act as a panacea for problems like nutritional security. Hence, an attempt has been made in this paper to analyze the significance of pulses in food consumption and nutritional security vis a vis other food items. The analysis is based on the 55th and 66th rounds of National Sample Survey pertaining to years 1999 2000 and 2009 10, respectively, using simple descriptive statistics. The dietary pattern has shifted away from cereals and pulses toward fruits, vegetables, processed food and food items of animal origin. The decline in the consumption of pulses has lead to increase in malnutrition and decline in protein intake. Need of the hour is to increase production and availability of pulses by adopting various innovative measures like institutional and policy support, development and wider adoption of HYV and low cost technologies, proper extension services for production and marketing of pulses, development of value chain, etc.
An improvement of a lean burning condition of natural gas/diesel RCCI engine with a pre chamber by using hydrogen
Year: 2018

In CNG/Diesel reactivity controlled compression ignition (RCCI) engines, because of low reactivity fuel (natural gas) spread of flame in combustion chamber suffers process of combustion and also there is more unburned hydrocarbon emission in this type of engine due to flame spread, free combustion points, penetrating gas into rings and cavities. Using hydrogen as an additive can improve combustion process, improve engine performance and reduce emissions. By this research, a computational fluid dynamic modeling in coupling with Chemkin solver has been used to investigate the effects of hydrogen as an additive in RCCI CNG/Diesel internal combustion engine. Numerical results have been validated by a single cylinder Ricardo E6/MS engine that equipped by a standard Comet MK.V pre chamber. Three different concentrations (10% 20% and 30% in volume) of hydrogen have been studied by this modeling. Specification of Ricardo engine have been used for CFD modeling from IVC to EVO as a close system modeling. There is a good flow structure with good swirling flow before combustion that makes fuel more suitable for starting combustion. HRR diagrams show a delay in combustion by adding hydrogen in natural gas and air. IMEP, gross work and IFCE improved by 5.01% 5.01% and 5.04% in concentration of 30% hydrogen, respectively. There are a descend in mass fraction of UHC and CO in different hydrogen concentration that 30% H2 addition in fuel makes the amount of UHC and CO lower by 29.8% and 35.5% correspondingly. This is in a condition that in cylinder temperature rises about 2.9% by 30% of hydrogen adding. NOx emissions has been risen during adding H2 because of increasing temperature, this increment is about 23.1% at 30% hydrogen that can be an undesired effect of using H2 as an additive. In general, the simultaneous use of Pre chamber and hydrogen has been able to reduce the amount of CO and UHC, but the amount of nitrogen oxide has been increased.
