THE REDUCTION IN FINESTRUCTURE CONTAMINATION OF INTERNAL WAVE ESTIMATES FROM A TOWED THERMISTOR CHAIN
Year: 2015

Estimates of internal wave displacements based on towed thermistor array data have historically suffered badly from finestructure contamination. It is hypothesized that a substantial amount of such contamination may be removed by sampling the ocean with thermistors spaced in a close vertical pattern and by using appropriate internal wave displacement estimation techniques. Such a technique is described, and preliminary results based on data from a 5 centimeter vertical resolution chain are presented that indicate that a substantial reduction of finestructure contamination is achievable
Metabolic engineering of Escherichia coli for high level astaxanthin production with high productivity.
Venue: Metabolic engineering
Year: 2018

Astaxanthin is a reddish keto carotenoid classified as a xanthophyll found in various microbes and marine organisms. As a powerful antioxidant having up to 100 times more potency than other carotenoids such as b carotene, lutein, and lycopene, astaxanthin is a versatile compound utilized in animal feed, food pigment, health promotion and cosmetic industry. Here, we report development of metabolically engineered Escherichia coli capable of producing astaxanthin to a high concentration with high productivity. First, the heterologous crt genes (crtE, crtY, crtI, crtB, and crtZ) from Pantoea ananatis and the truncated BKT gene (trCrBKT) from Chlamydomonas reinhardtii were introduced to construct the astaxanthin biosynthetic pathway. Then, eight different fusion tags were examined by attaching them to the N or C terminus of the trCrBKT membrane protein to allow stable expression and to efficiently guide trCrBKT to the E. coli membrane. When the signal peptide of OmpF and TrxA were tagged to the N terminus and C terminus of trCrBKT, respectively, astaxanthin production reached 12.90 mg/L (equivalent to 3.84 mg/gDCW) which was 2.08 fold higher than that obtained without tagging. Upon optimization of culture conditions, this engineered strain WLGB RPP harboring pAX15 produced 332.23 mg/L (5.38 mg/gDCW) of astaxanthin with the productivity of 3.79 mg/L/h by fed batch fermentation. In order to further increase astaxanthin production, in silico flux variability scanning based on enforced objective flux (FVSEOF) was performed to identify gene overexpression targets. The engineered strain WLGB RPP (pAX15, pTrc ispDF) which simultaneously overexpressing the ispD and ispF genes identified by FVSEOF produced astaxanthin to a higher concentration of 377.10 mg/L (6.26 mg/gDCW) with a productivity of 9.20 mg/L/h upon induction with 1 mM IPTG. When cells were induced with 0.5 mM IPTG to reduce the metabolic burden, astaxanthin concentration further increased to 432.82 mg/L (7.12 mg/gDCW) with a productivity of 9.62 mg/L/h. To more stably maintain plasmid during the fed batch fermentation of WLGB RPP (pAX15, pTrc ispDF) the post segregational killing hok/sok system was introduced. This strain produced 385.04 mg/L (6.98 mg/gDCW) of astaxanthin with a productivity of 7.86 mg/L/h upon induction with 0.5 mM IPTG. The strategies reported here will be useful for the enhanced production of astaxanthin and related carotenoid products by engineered E. coli strains.
Manejo de costos de alimentos y bebidas en restaurantes de reciente creacion en base al precio de venta, Riobamba 2012
Year: 2013

La presente investigacion se realizo mediante un estudio descriptivo de corte transversal al manejo de costos de alimentos y bebidas en restaurantes de reciente creacion en base al precio de venta. Se aplico encuestas a 23 restaurantes con lo cual se recolecto, midio y valoro las variables de produccion para determinar deficiencias, debilidades, fortalezas y oportunidades de los procesos en el control de los costos en un restaurante. Ademas se aplico una matriz de observacion en cuanto a servicios vs. precio determinando si los precios de los menus de estos restaurantes se justifican por el servicio y la calidad de las instalaciones. Mediante el estudio de costos de materia prima directa del periodo de 3 meses se noto un incremento del 3,5% en el segundo mes, y un 6% en el tercer mes. De las utilidades expresadas en dolares encontramos una disminucion del 22% en el segundo mes, y para el tercer mes se noto una reduccion del 38% A pesar del incremento en los costos de los insumos, se mantuvo el precio de venta ya que el margen de utilidad amortiguo la disminucion de la misma, evitando tomar medidas extremas como el incremento directo al P.V.P. para mantener la clientela fija que poseen estos establecimientos. Se concluyo que el manejo de costos de los restaurantes de reciente creacion no es de forma tecnica, obteniendo resultados deficientes al final de cada periodo aumentando asi la incertidumbre. Se recomienda aplicar los controles que se enuncian para un manejo de costos profesional.
Electricity Smart Meters Interfacing the Households
Venue: IEEE Transactions on Industrial Electronics
Year: 2011

The recent worldwide measures for energy savings call for a larger awareness of the household energy consumption, given the relevant contribution of domestic load to the national energy balance. On the other hand, electricity smart meters together with gas, heat, and water meters can be interconnected in a large network offering a potential value to implement energy savings and other energy related services, as long as an efficient interface with the final user is implemented. Unfortunately, so far, the interface of such devices is mostly designed and addressed at the utilities supervising the system, giving them relevant advantages, while the communication with the household is often underestimated. This paper addresses this topic by proposing the definition of a local interface for smart meters, by looking at the actual European Union and international regulations, at the technological solutions available on the market, and at those implemented in different countries, and, finally, by proposing specific architectures for a proper consumer oriented implementation of a smart meter network.
A Case Study of Efficacy and Challenges in Practical Human in Loop Evaluation of NLP Systems Using Checklist
Venue: HUMEVAL
Year: 2021

Despite state of the art performance, NLP systems can be fragile in real world situations. This is often due to insufficient understanding of the capabilities and limitations of models and the heavy reliance on standard evaluation benchmarks. Research into non standard evaluation to mitigate this brittleness is gaining increasing attention. Notably, the behavioral testing principle 'Checklist' which decouples testing from implementation revealed significant failures in state of the art models for multiple tasks. In this paper, we present a case study of using Checklist in a practical scenario. We conduct experiments for evaluating an offensive content detection system and use a data augmentation technique for improving the model using insights from Checklist. We lay out the challenges and open questions based on our observations of using Checklist for human in loop evaluation and improvement of NLP systems.  The paper contains examples of content with offensive language. The examples do not represent the views of the authors or their employers towards any person(s) group(s) practice(s) or entity/entities.
Significance of activation energy in radiative peristaltic transport of Eyring Powell nanofluid
Year: 2020

In this article we illustrate the features of first order chemical reaction and activation energy on MHD peristaltic transport of Eyring Powell nanofluid. Modeling and analysis in the presence of heat generation/absorption are studied. Energy equation is modeled by considering thermal radiation, Joule heating and dissipation. Velocity slip is imposed on flexible channel walls. Heat convective condition is analyzed. For mathematical modeling the Buongiorno nanofluid model is used. Thermophoresis and Brownian diffusion are under consideration. The governing partial differential equations are first reduced to the system of ordinary differential equations by applying relevant transformations and then shooting technique is used to obtain the numerical results. Relevant problem for low Reynold number and long wavelength is reduced. Numerical results for velocity, temperature, concentration, heat transfer coefficient and trapping are analyzed. Expressions for coefficient of skin friction, Nusselt and Sherwood numbers at the channel wall are examined. Influence of Eyring Powell variables on velocity shows opposite behavior. Velocity of fluid increases against velocity slip parameter. Temperature increases for higher values of thermophoresis and Brownian motion while it decays against thermal Biot number. Concentration enhances for higher values of radiation and activation energy variables. Heat transfer coefficient is an increasing function of heat generation.

False Information Narratives: The IRA's 2016 Presidential Election Facebook Campaign
Year: 2019

The issue of Russian interference in the 2016 U.S. Presidential election has been widely debated by scholars and journalists. However, these works have not fully analyzed the ads that have been released by Facebook and the U.S. Congress. This project uses a case study to analyze the ads posted by the Russian affiliated Internet Research Agency, considering the quantities of ads targeted to particular geographic locations, the frequency of targeting for unique keywords, and the reach and impressions of each of the ads. Further, these results are compared to results from best practices in traditional social media campaigns as a way to better understand the goals and potential impacts of the IRA ads. In conclusion, the project, by analyzing the full set of IRA ads, sheds new light on the way false information narratives were leveraged by the Russian linked IRA.

Knowledge and risk perception towards Lassa fever infection among residents of affected communities in Ebonyi State, Nigeria: implications for risk communication
Venue: BMC Public Health
Year: 2020

Lassa fever (LF) is an epidemic prone zoonotic disease prevalent in Nigeria and Ebonyi State is a high burden area in Nigeria. Low risk perceptions have been reported to prevent appropriate preventive behaviours. We investigated the knowledge and risk perception of residents towards LF and determined the factors influencing their risk perception in communities that have reported confirmed cases of LF.  We conducted a cross sectional study in the affected wards in Abakaliki Local Government Area (LGA) We interviewed 356 adult respondents recruited across 6 settlements in 3 of the affected wards through multistage sampling technique. Information on participants' knowledge of LF, their risk perception using the health belief model as well as factors influencing risk perception were obtained. We estimated the proportions of respondents with good knowledge and high risk perceptions. We also explored the relationship between risk perception, knowledge and sociodemographic characteristics using Chi Square and logistic regression at 5% level of significance.  The mean age of the participants was 33.3 12.2 years, 208 (63.2% were females, 230 (69.9% were married and 104 (31.6% had attained tertiary education. Though 99.1% were aware of LF infection, 50.3% among them had poor knowledge of LF symptoms and risk factors, 92.9% had high risk perception of severity, 72.4% had a high feeling of susceptibility towards LF infection, 82.5% had a high perceived self efficacy towards LF infection, 63.5% had a low perceived benefit of LF preventive practices and 31.8% had high perceived barrier towards LF preventive practices. Good knowledge of LF was the only significant factor influencing risk perception; perceived severity: (COR: 3.0, 95%CI: 1.2 7.8) perceived susceptibility (AOR: 2.0, 95%CI: 1.25 3.3) and perceived benefit (COR: 2.1, 95%CI: 1.3 3.3)  Good knowledge of LF influences risk perception towards LF which has great import on LF preventive practices. A gap exists in the content and acceptance of LF risk communication information in the LGA. There is a need to review the risk communication messages in the state towards LF in the community with special focus on the males and younger population.
The Phytochemical, Antifungal, and First Report of the Antiviral Properties of Egyptian Haplophyllum tuberculatum Extract
Venue: Biology
Year: 2020

In this study, ethanol whole plant extract (WPE) of Haplophyllum tuberculatum was characterized and tested for its antifungal and antiviral activities against Fusarium culmorum, Rhizoctonia solani and tobacco mosaic virus (TMV) High Performance Liquid Chromatography (HPLC) analysis showed that the main phytochemical constituents of H. tuberculatum WPE were resveratrol (5178.58 mg/kg) kaempferol (1735.23 mg/kg) myricetin (561.18 mg/kg) rutin (487.04 mg/kg) quercetin (401.04 mg/kg) and rosmarinic acid (387.33 mg/kg) By increasing H. tuberculatum WPE at concentrations of 1% 2% and 3% all of the fungal isolates were suppressed compared to the two positive and negative controls. Under greenhouse conditions, WPE treated Chenopodium amaranticolor plants strongly inhibited TMV infection and significantly reduced TMV accumulation levels when compared to non treated plants. Moreover, the induction of systemic resistance with significant increases in the transcriptional levels of the pathogenesis related protein 1 (PR 1) chalcone synthase (CHS) and hydroxycinnamoyl CoA quinate transferase (HQT) genes for treated plants were noticed at 3 and 5 days post inoculation (dpi) for both assays. To the best of our knowledge, this is the first reported observation of the antiviral activity of H. tuberculatum extract against plant viral infections. Finally, the results obtained suggest that H. tuberculatum WPE can be considered a promising source of both antifungal and antiviral substances for practical use and for developing plant derived compounds for the effective management of plant diseases.

Solving the Stable Set Problem in Terms of the Odd Cycle Packing Number
Venue: FSTTCS
Year: 2014

The classic stable set problem asks to find a maximum cardinality set of pairwise non adjacent vertices in an undirected graph G. This problem is NP hard to approximate with factor n^{1 epsilon} for any constant epsilon>0 [Hastad/Acta Mathematica/1996; Zuckerman/STOC/2006] where n is the number of vertices, and therefore there is no hope for good approximations in the general case. We study the stable set problem when restricted to graphs with bounded odd cycle packing number ocp(G) possibly by a function of n. This is the largest number of vertex disjoint odd cycles in G. Equivalently, it is the logarithm of the largest absolute value of a sub determinant of the edge node incidence matrix A_G of G. Hence, if A_G is totally unimodular, then ocp(G)=0. Therefore, ocp(G) is a natural distance measure of A_G to the set of totally unimodular matrices on a scale from 1 to n/3. When ocp(G)=0, the graph is bipartite and it is well known that stable set can be solved in polynomial time. Our results imply that the odd cycle packing number indeed strongly influences the approximability of stable set. More precisely, we obtain a polynomial time approximation scheme for graphs with ocp(G)=o(n/log(n) and an alpha approximation algorithm for any graph where alpha smoothly increases from a constant to n as ocp(G) grows from O(n/log(n) to n/3. On the hardness side, we show that, assuming the exponential time hypothesis, stable set cannot be solved in polynomial time if ocp(G)=Omega(log^{1+epsilon}(n) for some epsilon>0. Finally, we generalize a theorem by Gyori et al. [Gyori et al./Discrete Mathematics/1997] and show that graphs without odd cycles of small weight can be made bipartite by removing a small number of vertices. This allows us to extend some of our above results to the weighted stable set problem.

Braces for Idiopathic Scoliosis in Adolescents
Venue: Spine
Year: 2016

A Cochrane systematic review.  To evaluate the efficacy of bracing for adolescents with AIS versus no treatment or other treatments, on quality of life, disability, pulmonary disorders, progression of the curve, psychological, and cosmetic issues.  Idiopathic scoliosis is a three dimensional deformity of the spine. The most common form is diagnosed in adolescence. Although adolescent idiopathic scoliosis (AIS) can progress during growth and cause a surface deformity, it is usually not symptomatic.  We searched CENTRAL, MEDLINE, EMBASE, five other databases, and two trials registers up to February 2015. We also checked reference lists and hand searched grey literature. Randomized controlled trials (RCTs) and prospective controlled cohort studies comparing braces with no treatment, other treatment, surgery, and different types of braces for adolescent with AIS. We used standard methodological procedures expected by the Cochrane Collaboration.  We included seven studies. Five were planned as RCTs, two as prospective controlled clinical trials. One RCT failed completely, another was continued as an observational study. There was very low quality evidence from one small RCT that quality of life (QoL) during treatment did not differ significantly between rigid bracing and observation.  Two studies showed that bracing did not change QoL during treatment, and QoL, back pain psychological and cosmetic issues in the long term (16 years. All articles showed that bracing prevented curve progression. The high rate of failure of RCTs demonstrates the huge difficulties in performing RCTs in a field where parents reject randomization of their children.
