Towards Operationally Robust Fuel Cell Systems for Aeronautical Applications (2015)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Fuel cell technology will play a decisive role in the process of achieving the ambitious ecological goals of the aviation industry. However, apart from its obvious environmental advantages, the integration of fuel cell technology into commercial aircraft represents a challenging task in terms of operational and economical aspects.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;Since fuel cell systems are currently exposed to an intense competition with well-established power sources onboard an aircraft, engineers are in pursuit of highly efficient and particularly lightweight fuel cell systems. Supported by model-based design in conjunction with elaborate optimization techniques this pursuit has led to highly specialized systems. These systems tend to use their components to full capacity, which typically implies marginal system robustness. In consequence, preliminary design studies propose fuel cell systems that are sensitive to partial faults, or even to the slightest deviation, or degradation of their components' behavior.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;Non-functional requirements such as reliability, availability, dispatchability and durability will become key factors for the acceptance of fuel cells as alternative power sources onboard aircraft. These requirements demand the taking of coordinated measures in both &lt;i&gt;Systems Architecting&lt;/i&gt; and &lt;i&gt;Sizing&lt;/i&gt;, since the potential of measures such as adding redundancy to the system's architecture or making use of modular approaches is directly bound to the reliability of subsystems and their components. A component's reliability, however, strongly depends on its operating point and thus on the operating point of connected components. Hence, an operation envelope-oriented sizing of subsystems and components becomes an important factor.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;This paper reveals and illustrates the crucial issue of highly sensitive, high-performance fuel cell systems and proposes and discusses measures regarding &lt;i&gt;Systems Architecting&lt;/i&gt; and &lt;i&gt;Sizing&lt;/i&gt; in order to enhance the system's operational robustness while still keeping track of key performance indicators such as weight and efficiency.&lt;/div&gt;&lt;/div&gt;
ZFP91 zinc finger protein expression pattern in normal tissues and cancers (2019)

Zinc finger protein 91 (ZFP91) gene has been recently acknowledged to possess oncogenic properties. To date, its expression has been examined only in a handful of human organs and cancer types. The aim of the present study was to characterize, for the first time, the ZFP91 expression pattern in a range of human tissues and cancer types. ZFP91 mRNA expression was examined using Cancer Survey cDNA sets. Utilized cDNA samples represented 15 human organs and 17 cancer types. ZFP91 mRNA expression was the highest in the testes and lymph nodes. It was downregulated in testis cancer, lymphoma and thyroid cancer, and upregulated in prostate cancer. Among the analyzed cancer types, ZFP91 expression was markedly elevated in sarcomas and melanoma. On a protein level, a large-scale reverse phase protein array was employed providing samples from 11 organ types and from cancers derived from these organs. ZFP91 protein expression was revealed to be generally stable across the tested samples and was only moderately elevated in breast, ovarian and pancreatic cancers. To the best of our knowledge, this is the first study to thoroughly analyze the ZFP91 expression pattern in human tissues and cancers. The obtained results provide the foundation for further work aiming to reveal its full biological significance.

Textless Speech Emotion Conversion using Decomposed and Discrete Representations (2021)

Speech emotion conversion is the task of modifying the perceived emotion of a speech utterance while preserving the lexical content and speaker identity. In this study, we cast the problem of emotion conversion as a spoken language translation task. We decompose speech into discrete and disentangled learned representations, consisting of content units, F0, speaker, and emotion. First, we modify the speech content by translating the content units to a target emotion, and then predict the prosodic features based on these units. Finally, the speech waveform is generated by feeding the predicted representations into a neural vocoder. Such a paradigm allows us to go beyond spectral and parametric changes of the signal, and model non-verbal vocalizations, such as laughter insertion, yawning removal, etc. We demonstrate objectively and subjectively that the proposed method is superior to the baselines in terms of perceived emotion and audio quality. We rigorously evaluate all components of such a complex system and conclude with an extensive model analysis and ablation study to better emphasize the architectural choices, strengths and weaknesses of the proposed method. Samples and code will be publicly available under the following link: https://speechbot.github.io/emotion.
Dynamic speckle analysis using the event-based block matching algorithm (2021)

Dynamic speckle analysis (DSA) is a non-invasive method to detect movements of the inspected objects. By illuminating the observed sample using a coherent light source, motion information can be obtained from a series of reflecting speckle patterns. Conventional DSA methods record the intensity of the speckle patterns using a frame-based imaging sensor. Here, we propose a novel implementation of DSA using the event sensor which captures the brightness changes of the dynamic speckle patterns with high temporal resolution and low latency. Our method is based on block matching algorithm in which the captured event stream is divided into many non-overlapping blocks and motion information can be computed by searching for the most likely blocks. The experiment results demonstrate the feasibility of our proposed method in different dynamic levels and this work will be beneficial for various applications such as biomedical imaging and material science.
Authorship Studies and the Dark Side of Social Media Analytics (2020)

The computational analysis of documents to learn about their authorship (also known as authorship attribution and/or authorship profiling) is an increasingly important area of research and application of technology. This paper discusses the technology, focusing on its application to social media in a variety of disciplines. It includes a brief survey of the history as well as three tutorial case studies, and discusses several significant applications and societal benefits that authorship analysis has brought about. It further argues, though, that while the benefits of this technology have been great, it has created serious risks to society that have not been sufficiently considered, addressed, or mitigated.

Population Attentional Field Modeling (2013)

The stimulus evoked fMRI signal of single voxels in human visual cortex can be accurately predicted using a population receptive field (pRF) model (Dumoulin, 2008). We have adapted this approach to explore the effects of visual attention on single voxels. While fixating at a center marker, subjects (4) were cued to covertly attend to a specific target location within a dartboard-like array of stimulus segments that slowly rotated about fixation at 0.75 rpm. In attention runs, subjects continuously tracked a single target at 8[sup]o[/sup] eccentricity within the array. In sensory runs, the previously attended segment was presented in isolation while subjects performed an attention task at fixation. In the attention condition, voxels having pRFs positioned along the trajectory of the target segment were differentially activated when the focus of attention passed over their pRF. These voxels were also activated in the sensory condition when the isolated stimulus segment passed over the pRF. Thus, the duration of fMRI activation was proportional to either (1) the width of the attentional focus or (2) the width of the stimulus segment, thereby allowing a direct comparison of the relative sizes of the two. To compute the relative widths precisely for each voxel, we fit the empirical data with a timecourse generated by a model composed of the stimulus sequence, the attentional field, the voxel's estimated pRF, and the temporal hemodynamic response function. The resulting model parameters were compared to estimate the relative sizes of the attentional field and the sensory stimulus. Recent models of visual attention indicate that the size of the attentional field relative to a visual stimulus and sensory pRF are key factors in determining the behavioral effects of attention (Reynolds, 2009). The method described here permits empirical measurement of the attentional field size thereby providing key information for models of attention. Meeting abstract presented at VSS 2013
An Evaluation of the Genotoxic Potential of Glyphosate (1988)

An Evaluation of the Genotoxic Potential of Glyphosate. Li, A. P., AND LONG, T. J. (1988). &lt;it&gt;Fundam. Appl. Toxicol&lt;/it&gt;. &lt;b&gt;10,&lt;/b&gt; 537–546. The potential genotoxicity of glyphosate, the active ingredient in Roundup herbicide, was tested in a vanety of well-established &lt;it&gt;in vitro&lt;/it&gt; and &lt;it&gt;in vivo&lt;/it&gt; assays including the &lt;it&gt;Salmonella lyphimurium&lt;/it&gt; and &lt;it&gt;Eschenchia coli&lt;/it&gt; WP-2 reversion assays, recombination (rec-assay) with &lt;it&gt;Bacillus subtilis&lt;/it&gt;, Chinese hamster ovary cell gene mutation assay at the hypoxanthine&amp;sol;guanine phosphoribosyl transferase gene locus, hepatocyte primary culture&amp;sol; DNA repair assay, and &lt;it&gt;in vivo&lt;/it&gt; cytogenetics assay in rat bone marrow. No genotoxic activity was observed in the assays performed. The data suggest that glyphosate should not pose a genetic risk to man.
dSEDA: a Differential Series Elastic Damped Actuator (2022)

Compliant actuation bestows robots with the ability to cope with unstructured environments, move with agility, and interact safely with humans at the expense of reduced tracking accuracy. The inclusion of dampening components aims to reduce oscillatory dynamics and partially restore precision without sacrificing the previously obtained characteristics. This paper introduces the concept and design of a novel damped compliant actuator suitable for building multi-degree of freedom systems. The proposed unit has a unique actuator topology that has never been seen before in the literature. The gearbox is used as a differential component, allowing the design of compact units without giving up safety and accuracy enhancements. We present and analyze the actuator's model and experimentally characterize the actuator prototype and the elastic and damping component.
Microfabricated Electrophoresis Chips for Simultaneous Bioassays of Glucose, Uric Acid, Ascorbic Acid, and Acetaminophen (2000)

A micromachined capillary electrophoresis chip is described for simultaneous measurements of glucose, ascorbic acid, acetaminophen, and uric acid. Fluid control is used to mix the sample and enzyme glucose oxidase (GOx). The enzymatic reaction, a catalyzed aerobic oxidation of glucose to gluconic acid and hydrogen peroxide, occurs along the separation channel. The enzymatically liberated neutral peroxide species is separated electrophoretically from the anionic uric and ascorbic acids in the separation/reaction channel. The three oxidizable species are detected at the downstream gold-coated thick-film amperometric detector at different migration times. Glucose can be detected within less than 100 s, and detection of all electroactive constituents is carried out within 4 min. Measurements of glucose in the presence of acetaminophen, a neutral compound, are accomplished by comparing the responses in the presence and absence of GOx in the running buffer. The reproducibility of the on-chip glucose measurements is improved greatly by using uric acid as an internal standard. Factors influencing the performance, including the GOx concentration, field strength, and detection potential, are optimized. Such coupling of enzymatic assays with electrophoretic separations on a microchip platform holds great promise for rapid testing of metabolites (such as glucose or lactate), as well as for the introduction of high-speed clinical microanalyzers based on multichannel chips.
Refactoring the Concise Biosynthetic Pathway of Cyanogramide Unveils Spirooxindole Formation Catalyzed by a P450 Enzyme (2020)

Cyanogramide (1) from the marine actinomycete Actinoalloteichus cyanogriseus WH1-2216-6 features a unique spirooxindole skeleton and exhibits significant bioactivity to efficiently reverse drug resistance in tumor cells. The biosynthetic gene cluster of 1 in A. cyanogriseus WH1-2216-6 was identified and refactored by promoter engineering for heterologous expression in Streptomyces coelicolor YF11, thereby enabling the production of 1 and five new derivatives. Interesting, four of them, including 1, were identified as enantiomeric mixtures in different ratios. The functions of tailoring enzymes, including two methyltransferases (CyaEF), and three cytochrome P450 monooxygenases (CyaGHI) were confirmed by gene inactivation and feeding experiments, leading to the elucidation of a concise biosynthetic pathway for 1. Notably, CyaH was biochemically verified to catalyze the formation of the spirooxindole skeleton in 1 through an unusual carbocation-mediated semipinacol-type rearrangement reaction.
Electrochemical kinetics of the 0.5Li2MnO3·0.5LiMn0.42Ni0.42Co0.16O2 ‘composite’ layered cathode material for lithium-ion batteries (2012)

The ‘composite’ layered material of 0.5Li2MnO3·0.5LiMn0.42Ni0.42Co0.16O2 has been successfully prepared by the solid state reaction method, and was characterized by XRD and SEM methods. The kinetics of the electrochemical insertion and extraction of lithium ions during the first three cycles in this material was investigated in detail by the open-circuit voltage (OCV), galvanostatic intermittent titration technique (GITT), and electrochemical impedance spectroscopy (EIS) methods. The activation energies (Ea) of interfacial lithium ion transfer at various oxidation–reduction reactions were evaluated from the temperature-dependence of lithium ion transfer resistance. The results show that the electrochemical kinetics of the lithium ion extraction and insertion reactions in the first three cycles of this ‘composite’ material is mainly controlled by the Li2MnO3 and Li2MnO3-related components in this material. The lithium ion extraction processes from the Li2MnO3 component and LiMnO2 component (after the 1st cycle) are kinetically limited as compared with that from the LiMn0.42Ni0.42Co0.16O2 component, and the lithium ion insertion processes into the MnO2 (after the 1st cycle) component are kinetically limited as compared with that into the Mn0.42Ni0.42Co0.16O2 component. In addition, the interface reaction of the lithium ion into the Mn0.42Ni0.42Co0.16O2 component is also easier than that of the lithium ion into the MnO2 component originated from the Li2MnO3 component.

Reconstruction of group-IV semiconductor surfaces : origin, energetics and consequences (2005)

This work presents extensive first-principles studies of the energetics and the reconstructions of the clean low-index (111), (110), (100) and high-index (113) surfaces of the three group- IV semiconductors diamond, silicon, and germanium. The calculations have been performed within density-functional-theory (DFT) using the local-density-approximation (LDA) and the repeated-slab approximation. Different reconstructions including the largest ones observed experimentally such as Si(111)7?7 and Si(110)16?2 have been investigated. The atomic geometries have been optimized in order to find the minimum of the total energy. For these atomic structures the electronic band structures have also been calculated. For the most interesting surface reconstructions scanning-tunneling-microscopy (STM) images have been simulated in order to make a comparison with experimentally observed surface images. Presented results highlight the physical origins of the reconstruction behavior in dependence on surface orientation and size of the group-IV atoms. Clear evidence for an opposite reconstruction behavior of diamond and Si or Ge surfaces is shown. Adatoms, interstitials, and symmetry-breaking distortions are unlikely for diamond as a consequence of the short interatomic distances and strong bonds. However, such elements of the surface reconstruction occur on Si and Ge surfaces. The complicated interplay of bonding, resulting atomic geometry, and accompanying electronic structure has been derived and used to discuss driving forces for the surface reconstruction. A rather complete data base of absolute surface energies of group-IV semiconductors is presented. For all the elements, there is a strong tendency to reduce substantially surface energies by taking into account surface reconstructions. The absolute surface energies have been used to discuss the equilibrium shapes of diamond, silicon and germanium.
Fair resource allocation in the citizens broadband radio service band (2017)

The Citizens Broadband Radio Service (CBRS) band has three tiers of users. The General Authorized Access (GAA) has the lowest priority and operates without a license. A Spectrum Access System (SAS) is responsible for managing spectrum among the users. The Federal Communications Commission (FCC) rules specify that GAA users be allocated resources in a fair manner, but the method to do so is left open. It is envisioned that there will be multiple SAS operators in a given region. Thus, fair partitioning of resources among SASs and fair allocation of spectrum to GAA users are important factors. In this paper, we present methods to partition resources among SASs and mechanisms that can be used by a SAS to allocate resources to a GAA user to ensure fairness.
Serum sphingomyelin levels are related to the clearance of postprandial remnant-like particles (2004)

It is known that sphingomyelin (SM) content is higher in apolipoprotein B-containing particles (BLps) than in high density lipoproteins and that BLp levels, including chylomicrons and their remnant particles, are positively related to atherosclerosis. To evaluate the relationship between serum SM and postprandial remnant particle levels, we determined SM, triglyceride (TG), and cholesterol levels in serum and in remnant-like particles (RLPs) before and 3, 5, 7, and 10 h after a high-fat meal in 31 healthy subjects. We found that serum SM, like serum TG, was increased to its maximum 3 h after fat loading and then gradually decreased to basal levels after 10 h. More important, we determined that SM and TG levels in RLPs were parallel. Serum SM was positively correlated with serum TG (P <0.001), RLP SM (P <0.001), RLP TG (P <0.001), and RLP cholesterol (P <0.001) levels. It is our conclusion that serum SM is a marker for the clearance of RLPs.
Sprint (2011)

Remote data access latency is a significant performance bottleneck in many modern programs that use remote databases and web services. We present Sprint - a run-time system for optimizing such programs by prefetching and caching data from remote sources in parallel to the execution of the original program. Sprint separates the concerns of exposing potentially-independent data accesses from the mechanism for executing them efficiently in parallel or in a batch. In contrast to prior work, Sprint can efficiently prefetch data in the presence of irregular or input-dependent access patterns, while preserving the semantics of the original program. We used Sprint to automatically improve the performance of several real-world Java programs that access remote databases (MySQL, DB2) and web services (Facebook, IBM's Yellow Pages). Sprint achieves speedups ranging 2.4x to 15.8x over sequential execution, which are comparable to those achieved by manually modifying the program for asynchronous and batch execution of data accesses. Sprint provides a simple interface that allows a programmer to plug in support for additional data sources without modifying the client program.
Dyssynergic Defecation is a Common Finding in Men with Chronic Constipation (2009)

Purpose: Background: Dyssynergic defecation (DD) is characterized by the inability to coordinate the series of events necessary to achieve evacuation of stool from the rectum. On anorectal manometry (ARM), DD is identified by paradoxical contraction of the anal sphincter during simulated defecation (Sim Def). By balloon expulsion testing (BET), DD is defined as the inability to pass a water filled balloon within a prescribed period of time. Few studies have evaluated the impact of age and gender on the prevalence and physiology of DD in adults with chronic constipation (CC). Aims: To understand the effects of age and gender on DD through an analysis of ARM and BET results from patients with CC. Methods: We reviewed results from ARM and BET performed in all patients with CC referred to a single tertiary care center from 2002 to 2007. Data collected included age, gender; Sim Def response during ARM (normal or abnormal); and BET (normal = able to pass a 50 cc water filled balloon in < 60 sec). We considered patients with DD to have abnormal results on both ARM and BET. Comparisons of dichotomous variables were performed using a chi-square test.Table: ARM & BET findings by genderTable: ARM & BET findings by age
