Towards a Framework for Real Time Requirements Elicitation (2006)

Eliciting complete and correct requirements is a major challenge in software engineering and incorrect requirements are a constant source of defects. It often happens that requirements are either recorded only partially or not at all. Also, commonly, the rationale behind the requirements is not recorded or may be recorded, but is not accessible for the developers who need this information to support the decision making process when requirements change or need clarification. Our proposed framework is designed to solve those problems by using video to record the requirements elicitation meetings and automatically extract important stakeholder statements. Those statements are made available to the project members as video clips by using an RE database to access the statements and/or by the integration with the Sysiphus system.
AM1-xAlxO3-x (A = Na or K; M = Nb or Ta):  New Anion-Deficient Perovskite Oxides Exhibiting Oxide Ion Conduction (1996)

Anion-deficient perovskite oxides of the formula AM1-xAlxO3-x (A = Na or K; M = Nb or Ta) have been prepared for 0 < x ≤ 0.5. Diffraction experiments reveal that while the potassium compounds adopt orthorhombic/cubic perovskite structures similar to the parent KNbO3/KTaO3, the sodium compound, NaNb0.5Al0.5O2.5, possesses a brownmillerite/LaSrCuAlO5-like superstructure. 27Al NMR spectra show an exclusive tetrahedral oxygen coordination for Al(III) in NaNb0.5Al0.5O2.5 (I) and both tetrahedral and octahedral coordination for Al(III) in KNb0.5Al0.5O2.5 (II). The results suggest a long-range and short-range ordering of oxide ion vacancies in I and II respectively. Electrical conductivity measurements show a significant oxide ion conduction for KNb1-xAlxO3-x, with the conductivity increasing with x up to x = 0.5. The differences in the Arrhenius plots of the ionic conductivity of I and II have been rationalized in terms of the long-range and short-range ordering of oxide ion vacancies in the anion-deficient perovskite oxides.
Hepatoblastoma metastatic to brain mimicking intracranial hemorrhage: Case report and literature review (2012)

Many pediatric malignancies have a propensity for CNS metastases. Metastases have been reported to present as intracranial hemorrhages, occasionally without a discernible underlying mass. Lack of contrast enhancement should not be exclusionary criteria for intracranial metastases in these patients. Our case is a metastatic lesion presenting as an intracranial hemorrhage without an identifiable solid component on imaging in a patient with hepatoblastoma. Radiologists should consider metastases in cases of intracranial hemorrhage in a child.
Screening for Type 1 Diabetes in the General Population: A Status Report and Perspective (2022)

Most screening programs to identify individuals at risk for type 1 diabetes have targeted relatives of people living with the disease to improve yield and feasibility. However, ~90% of those who develop type 1 diabetes do not have a family history. Recent successes in disease modifying therapies to impact the course of early-stage disease have ignited the consideration of the need for and feasibility of population screening to identify those at increased risk. Existing population screening programs rely on genetic or autoantibody (AA) screening, and these have yielded significant information about disease progression and approaches for timing for screening in clinical practice. At the March 2021 Type 1 Diabetes TrialNet Steering Committee meeting, a session was held in which ongoing efforts for screening in the general population were discussed. This report reviews the background of these efforts and the details of those programs. Additionally, we present hurdles that need to be addressed for successful implementation of population screening and provide initial recommendations for individuals with positive screens so that standardized guidelines for monitoring and follow-up can be established.
Translocation of Platinum Anticancer Drugs by Human Copper ATPases ATP7A and ATP7B (2013)

Cisplatin, carboplatin, and oxaliplatin are widely used anticancer drugs. Their efficacy is strongly reduced by development of cell resistance. Down-regulation of CTR1 and up-regulation of the Cu-ATPases, ATP7A and ATP7B, have been associated to augmented drug resistance. To gain information on translocation of Pt drugs by human Cu-ATPases, we performed electrical measurements on the COS-1 cell microsomal fraction, enriched with recombinant ATP7A, ATP7B, and selected mutants, and adsorbed on a solid supported membrane. The experimental results indicate that Pt drugs activate Cu-ATPases and undergo ATP-dependent translocation in a fashion similar to that of Cu. We then used NMR spectroscopy and ESI-MS to determine the binding mode of these drugs to the first N-terminal metal-binding domain of ATP7A (Mnk1).
Maternity Care as a Global Health Policy Issue (2015)

ethos of global health policy as expressed in the Millennium Development Goals (MDGs) issued by the United Nations (United Nations, 2012).In fact, of all the eight MDGs, there has been least progress toward the realization of the global right of every woman to the best possible maternity care.This chapter focusses attention on these current paradoxical issues, drawing on four distinct case examples selected from low-resourced to middle-and high-resourced countries -Nepal, Chile, Canada and England.These countries provide examples of different institutional contexts, but all sharing the fact that healthcare has been subjected to saliently neoliberal reforms that emphasize cost containment through efficiency, and views healthcare provision as production of commodities for private markets or quasi-markets.We illustrate substantial diversity within and across these countries regarding universal healthcare coverage, effective midwifery workforces, welfare state policy in improving maternal health, private sector involvement in care provision, and women's right to maternity care. Maternal healthcare policy in global perspectiveMDG 5, Improve Maternal Health, aims to reduce maternal mortality ratio by three quarters between 1990 and 2015.The goal uses two indicators to measure whether or not the target has been achieved: the maternal mortality ratio (MMR) and, by 2015, universal access to reproductive health (WHO, 2010).The latter involves increasing access to antenatal care, reducing teen pregnancies, expanding access to family planning, and increasing contraceptive use.The post-2015 development agenda for MDG 5 provides a unique moment in time to ensure that the barriers to improved health for women and children health is placed firmly on the global
Error-Related EEG Potentials Generated During Simulated Brain–Computer Interaction (2008)

Brain-computer interfaces (BCIs) are prone to errors in the recognition of subject's intent. An elegant approach to improve the accuracy of BCIs consists in a verification procedure directly based on the presence of error-related potentials (ErrP) in the electroencephalogram (EEG) recorded right after the occurrence of an error. Several studies show the presence of ErrP in typical choice reaction tasks. However, in the context of a BCI, the central question is: "Are ErrP also elicited when the error is made by the interface during the recognition of the subject's intent?"; We have thus explored whether ErrP also follow a feedback indicating incorrect responses of the simulated BCI interface. Five healthy volunteer subjects participated in a new human-robot interaction experiment, which seem to confirm the previously reported presence of a new kind of ErrP. However, in order to exploit these ErrP, we need to detect them in each single trial using a short window following the feedback associated to the response of the BCI. We have achieved an average recognition rate of correct and erroneous single trials of 83.5% and 79.2%, respectively, using a classifier built with data recorded up to three months earlier.
Application of Nanoemulsions to Improve Food System Color, Flavor, Texture, and Preservation (2021)

Nanoemulsions are kinetically stable colloidal systems with a droplet size of 20–200 nm. They have potential application in the food industry, but current use is quite limited. Nanoemulsion technology can be used in food industry for various applications including delivery of micronutrients, bioactive food components like resveratrol, lycopene, tannins, lignan, indoles, etc. Further applications include, delivery of flavoring agents, coloring agents, antimicrobial agents into food products and drinks to enhance the nutritive benefits and appearance. Different oil soluble and fat-soluble ingredients can be incorporated effectively by the use of o/w or w/o or multiple types of nanoemulsions. Another potential application of this technology is to increase the shelf life of the food product. High energy as well as low energy techniques are available for the production of food grade nanoemulsions with sufficient shelf life. In this chapter we review the application of nanoemulsions technology in food processing, in terms of enhancing the bioavailability as well as product characteristics in terms of aroma, color, and appearance. The chapter reviews various investigations in food industry which make use of nanoemulsion technology for superior product performance.
Particle moment canting inCoFe2O4nanoparticles (2014)

Polarization-analyzed small-angle neutron scattering methods are used to determine the spin morphology in high crystalline anisotropy, 11 nm diameter ${\mathrm{CoFe}}_{2}{\mathrm{O}}_{4}$ nanoparticle assemblies with randomly oriented easy axes. In moderate to high magnetic fields, the nanoparticles adopt a uniformly canted structure, rather than forming domains, shells, or other arrangements. The observed canting angles agree quantitatively with those predicted from an energy model dominated by Zeeman and anisotropy competition, with implications for the technological use of such nanoparticles.
Static tests to assess acid mine drainage potential of copper sulfide flotation tailings (2023)

Most copper flotation tailings contain a significant amount of sulfide minerals that can generate effluent resulting from the oxidation of sulfides when they are exposed to oxygen and water. This study aimed to characterize and evaluate the acid drainage potential of five different copper flotation tailings, named samples I, II, III, IV, and V. Sample I was taken from an industrial operation, while Samples II, III, IV, and V were produced in pilot plant tests. All samples were characterized and submitted to static acid drainage tests, such as paste pH, Net Acid Generation (NAG) pH, and Modified Acid-Base Accounting (MABA). The sulfur as sulfide/total sulfur mass ratios varies from 0.40 up to 0.89 showing the presence of a high amount of minerals rich in pyrite and alunite, being higher than 13 wt% of pyrite in samples IV and V and around 19 wt% of alunite in sample III. Samples I and II presented a high number of alkaline elements, totalizing more than 8 wt% of K2 O+CaO+MgO, while samples III, IV, and V show the lowest amount of these elements (<4 wt%). Only samples III, IV, and V show Paste pH results lower than 5.0, indicating superficial oxidation on their surfaces and/or the presence of water-soluble acidity minerals. Due to the high pyrite content in samples III and IV, it was not possible to measure their NAG pH due to the high heat released with the addition of hydrogen peroxide. The low NAG pH obtained with sample III (5.30) was due to its high pyrite content (0.30 wt%) in comparison with the results obtained with sample I (NAG pH of 8.15 and 0.10 wt% of pyrite), and sample II (NAG pH of 8.18 and 0.10 wt% of pyrite). The MABA results show that samples III, IV and V presented acid drainage potential due to the neutralization potential (NP)/acidity potential (AP) ratio being lower than 1. On the other hand, samples I and II presented NP/AP ratio higher than 4, not showing potential to generate acid drainage. Due to these results, it is recommended to carry out acid drainage kinetic tests with samples III, IV, and V to determine the long-term weathering rates, evaluate lag time to acid generation and provide reaction rates for geochemical modeling.
Mortality and Morbidity by Month of Birth of Neonates Admitted to an Academic Neonatal Intensive Care Unit (2008)

Morbidity and mortality in infants admitted to an academic NICU did not change significantly over the academic year. These observations suggest that the quality of care of critically ill neonates is not decreased early in the academic year.

Sensing and communication protocols in cognitive sensor relay networks (2008)

We present sensing and communication protocols for a dual-hop sensor relay network operating on secondary basis in licensed spectrum. We consider a two-phase communication protocol: in the first phase, the source node transmits to the relay and in the second phase, the relay node transmits to the destination node. A naive sensing protocol is to perform sensing in slots that are scheduled prior to transmission in each phase. This leads to substantial loss in throughput and also can be an issue for delay-sensitive applications. To address this, we propose a sensing protocol wherein sensing is performed at the source node during the second transmission phase. Using a simple reward model, we show that the proposed protocol outperforms the naive protocol while providing better detection performance.
Simplification of Air Assisted Direct Injection via Performance Benchmarking (1999)

&lt;div class="htmlview paragraph"&gt;Air assisted direct injection systems have been in commercial production for four years having established themselves as a technical breakthrough in the pursuit of low-emission two-strokes, whilst providing the end-user with smooth operation and a significant reduction to fuel consumption. The same core technology has demonstrated significant advantages for automotive direct injected four-stroke engines.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;For the non-automotive sector, research has since aimed to provide manufacturers with alternate cost-function options, thus extending market penetration opportunities for low cost air assist DI.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;By extensively benchmarking the air assisted direct injection system applied to customer marine products, Orbital engineers are developing significantly simplified systems which inherit the most performance-critical aspects of the existing production system, whilst eliminating some of the components required in today's production system.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;This paper discusses the benchmarking process and the comparison of fuel system performance between simplified and existing production solutions. Also outlined is the process of function integration and component elimination used to realise a more favourable cost-function ratio.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Results from the application of simplified air assist systems to non-automotive engine designs are also presented.&lt;/div&gt;
Crystalline Silicon Solar Cells with Enhanced Light Trapping via Rear Side Diffraction Grating (2015)

Effective light trapping concepts are increasingly relevant for thinner crystalline silicon solar cells. Diffractive rear side structures can be designed to enhance optical light path lengths in the weakly absorbed infrared wavelength range. However, because of the rather difficult passivation of these nano-scale structures and possible plasma induced damages, the optical gain has so far not been shown on final device level for wafer-based crystalline silicon solar cells in combination with a high open circuit voltage. In this work, we fabricated and characterized silicon solar cells with an optically active layer at the rear side which is electrically decoupled from the silicon bulk by a thin, planar passivation layer. A binary diffraction grating was realized on the rear side via Nanoimprint Lithography (NIL) and plasma etching. For the rear side metallization a laser based foil process and photolithographically opened point contacts with evaporated aluminum were used as two alternative process routes. The best cell shows an EQE increase of up to 29 % absolute at 1100 nm compared to planar reference cells. This corresponds to a total Jsc gain of 1.2 mA/cm2 and a best cell efficiency of 19.4 % (Voc: 683.1 mV, Jsc: 35.4 mA/cm2, FF: 81.0 %) with planar front side and SiO2 antireflection coating. Optical simulations, which fit well to the experimental data, show that cell efficiencies of 20.8 % and 21.3 % can be reached with a planar front by using an optimized single layer (SiNxOy) or double layer (MgF, SiNx) ARC, respectively. By calculating Jsc for different cell thicknesses it is shown that a 100 μm thick solar cell incorporating the fabricated diffractive grating is expected to exhibit a higher Jsc than a planar cell with 250 μm thickness.
Model based diagnosis for automotive engines-algorithm development and testing on a production vehicle (1995)

A complete diagnostic algorithm is presented for detecting and isolating faults of actuators and sensors of an automotive engine. The algorithm is built around the concept of analytical redundancy and utilizes structured parity equations. The parity equations rely on a nonlinear and dynamic model, obtained by identification using data from a single production vehicle with a 3.1 l V-6 engine. Tests performed with the diagnostic algorithm on the same vehicle show excellent performance under different fault conditions. Several important issues require further investigation, including long-term climatic effects, vehicle aging, car-to-car variations, the automation of the calibration procedure and implementation in the face of processor limitations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Observation of Atomic Diffusion at Twin-Modified Grain Boundaries in Copper (2008)

Grain boundaries affect the migration of atoms and electrons in polycrystalline solids, thus influencing many of the mechanical and electrical properties. By introducing nanometer-scale twin defects into copper grains, we show that we can change the grain-boundary structure and atomic-diffusion behavior along the boundary. Using in situ ultrahigh-vacuum and high-resolution transmission electron microscopy, we observed electromigration-induced atomic diffusion in the twin-modified grain boundaries. The triple point where a twin boundary meets a grain boundary was found to slow down grain-boundary and surface electromigration by one order of magnitude. We propose that this occurs because of the incubation time of nucleation of a new step at the triple points. The long incubation time slows down the overall rate of atomic transport.
Attack Surface Modeling and Assessment for Penetration Testing of IoT System Designs (2018)

Security by Design becomes a significant aspect for establishing the Internet-of-Things (IoT) paradigm. In this paper, we present an approach to utilize virtual prototypes (VP) at system level to enable security evaluation along the design process. The proposed VP-based penetration testing framework provides an approach for attack surface and attack behavior modeling. By utilizing a modular, reconfigurable system simulation, an attack scenario can be assessed with different system alternatives. As the VP simulates both hardware (HW) and software (SW) of a single IoT-device as well as the interconnections of different devices a comprehensive system analysis can be executed. Our framework is based on a model-driven approach, which underlines the achieved degree of automation and its potential for industrial application. A comprehensive system analysis tool is the enabler to apply penetration testing, for identifying weak points in the system design and implementation, from early stages in the design flow. The overall approach is demonstrated by an automotive use case derived from real-world security flaws.

Long‐distance transport of mRNA via parenchyma cells and phloem across the host–parasite junction in Cuscuta (2008)

It has been shown that the parasitic plant dodder (Cuscuta pentagona) establishes a continuous vascular system through which water and nutrients are drawn. Along with solutes, viruses and proteins, mRNA transcripts are transported from the host to the parasite. The path of the transcripts and their stability in the parasite have yet to be revealed. To discover the route of mRNA transportation, the in situ reverse transcriptase-polymerase chain reaction (RT-PCR) technique was used to locally amplify host transcript within parasitic tissue. The stability of host mRNA molecules was also checked by monitoring specific transcripts along the growing dodder thread. Four mRNAs, alpha and beta subunits of PYROPHOSPHATE (PPi)-DEPENDENT PHOSPHOFRUCTOKINASE (LePFP), the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), and GIBBERELLIC ACID INSENSITIVE (LeGAI), were found to move from host (tomato (Solanum lycopersicum)) to dodder. LePFP mRNA was localized to the dodder parenchyma cells and to the phloem. LePFP transcripts were found in the growing dodder stem up to 30 cm from the tomato-dodder connection. These results suggest that mRNA molecules are transferred from host to parasite via symplastic connections between parenchyma cells, move towards the phloem, and are stable for a long distance in the parasite. This may allow developmental coordination between the parasite and its host.
