Glycosylhydrazides, a New Class of Sugar Surfactant. Preparation and Amphiphilic Properties of 1-Glycosyl-2-Acylhydrazines (2000)

ABSTRACT The synthesis and the amphiphilic properties of 1-glycosyl-2-acylhydrazines are described. This new class of surfactants, referred to as glycosylhydrazides, is easily available from a reducing sugar and hydrazides without protection. Seven hydrazides having an alkyl chain of up to fourteen carbon atoms, are coupled with glucose giving 1-glucosyl-2-acylhydrazines in good yields; 1-maltosyl-2-octanoylhydrazine, as a typical disaccharide-based surfactant, is prepared as well. Critical micellar concentrations of these surfactants range from 0.04 to 252 mM.
Management of Adult Leydig-Cell Testicular Tumors: Assessing the Role of Laparoscopic Retroperitoneal Lymph Node Dissection (2003)

Laparoscopic RPLND is a safe, minimally invasive procedure for Leydig-cell tumors. Additional clinical experience is required to evaluate its effectiveness for pathologic stage II tumors and to determine if a therapeutic advantage can be realized with a protocol employing laparoscopic RPLND for adult Leydig-cell tumors.
Symmetry issues in the hybridization of multi-mode waves with resonators: an example with Lamb waves metamaterial (2015)

Locally resonant metamaterials derive their effective properties from hybridization between their resonant unit cells and the incoming wave. This phenomenon is well understood in the case of plane waves that propagate in media where the unit cell respects the symmetry of the incident field. However, in many systems, several modes with orthogonal symmetries can coexist at a given frequency, while the resonant unit cells themselves can have asymmetric scattering cross-sections. In this paper we are interested in the influence of symmetry breaking on the hybridization of a wave field that includes multiple propagative modes. The A0 and S0 Lamb waves that propagate in a thin plate are good candidates for this study, as they are either anti-symmetric or symmetric. First we designed an experimental setup with an asymmetric metamaterial made of long rods glued to one side of a metallic plate. We show that the flexural resonances of the rods induce a break of the orthogonality between the A0/S0 modes of the free-plate. Finally, based on numerical simulations we show that the orthogonality is preserved in the case of a symmetric metamaterial leading to the presence of two independent polariton curves in the dispersion relation.

Functionalized 1′‐Substituted Iodoferrocenes and Their Pd‐Catalyzed Heck Cross‐Coupling Reactions (2016)

Abstract This paper describes the preparation of a variety of 1′‐substituted iodoferrocenes from 1‐iodo‐1′‐(tri‐ n ‐butyltin)ferrocene by an electrophilic substitution of the tri‐ n ‐butyltin moiety with functionalized acylium and benzoylium species. Additionally, we demonstrate a Heck coupling protocol for these functionalized iodoferrocenes with ethenylferrocene.

Identification of high spin states inZr100 (2006)

Eight new high spin states and 23 new \ensuremath{\gamma} transitions have been identified in $^{100}\mathrm{Zr}$ from studies of $^{252}\mathrm{Cf}$ spontaneous fission with Gammasphere. A near-spherical excited band in $^{100}\mathrm{Zr}$ based on the 331.1 keV ${0}^{+}$ state is extended from ${4}^{+}$ up to ${12}^{+}$. A $\ensuremath{\Delta}I=1$ band with band-head energy of 2316.1 keV is extended.
A Survey of NLP-Related Crowdsourcing HITs: what works and what does not (2021)

Crowdsourcing requesters on Amazon Mechanical Turk (AMT) have raised questions about the reliability of the workers. The AMT workforce is very diverse and it is not possible to make blanket assumptions about them as a group. Some requesters now reject work en mass when they do not get the results they expect. This has the effect of giving each worker (good or bad) a lower Human Intelligence Task (HIT) approval score, which is unfair to the good workers. It also has the effect of giving the requester a bad reputation on the workers' forums. Some of the issues causing the mass rejections stem from the requesters not taking the time to create a well-formed task with complete instructions and/or not paying a fair wage. To explore this assumption, this paper describes a study that looks at the crowdsourcing HITs on AMT that were available over a given span of time and records information about those HITs. This study also records information from a crowdsourcing forum on the worker perspective on both those HITs and on their corresponding requesters. Results reveal issues in worker payment and presentation issues such as missing instructions or HITs that are not doable.
Non-covalent pomegranate (Punica granatum) hydrolyzable tannin-protein complexes modulate antigen uptake, processing and presentation by a T-cell hybridoma line co-cultured with murine peritoneal macrophages (2016)

In this work we characterize the interaction of pomegranate hydrolyzable tannins (HT) with hen egg-white lysozyme (HEL) and determine the effects of non-covalent tannin-protein complexes on macrophage endocytosis, processing and presentation of antigen. We isolated HT from pomegranate and complex to HEL, the resulting non-covalent tannin-protein complex was characterized by gel electrophoresis and MALDI-TOF MS. Finally, cell culture studies and confocal microscopy imaging were conducted on the non-covalent pomegranate HT-HEL protein complexes to evaluate its effect on macrophage antigen uptake, processing and presentation to T-cell hybridomas. Our results indicate that non-covalent pomegranate HT-HEL protein complexes modulate uptake, processing and antigen presentation by mouse peritoneal macrophages. After 4 h of pre-incubation, only trace amounts of IL-2 were detected in the co-cultures treated with HEL alone, whereas a non-covalent pomegranate HT-HEL complex had already reached maximum IL-2 expression. Pomegranate HT may increase rate of endocytose of HEL and subsequent expression of IL-2 by the T-cell hybridomas.
Tools Deployment Strategy for the Implementation of Integrated Product and Process Development (IPPD) in Science and Technology (S&T) (1997)

Abstract : The purpose of this task was to identify tools and methods that could support the AFMC/ST Science and Technology (S&T) Integrated Product and Process Development (IPPD) Initiative. The intent is to deploy Commercial off the Shelf (COTS) software products that will aid the S&T community in implementing the IPPD strategy and, in turn, reduce program management and operation costs. This effort bad three general objectives: (1) Gather user needs for tools to support the implementation of the IPPD process. (2) Provide a market assessment to determine whether commercial tools exist that could support these needs. (3) Recommend a tools development strategy for deploying tools throughout the Air Force S&T community. Program managers at five major Air Force R&D organizations underwent structured interviews to determine their tool requirements in each of four areas: (Technology) Requirements Management, (Value Judgment via) Group Consensus, (Program Management) Workflow, and (Design) Value Analysis. COTS tools were evaluated against those requirements and recommendations were made for tool selection and further tool development.
PreCo: A Large-scale Dataset in Preschool Vocabulary for Coreference Resolution (2018)

We introduce PreCo, a large-scale English dataset for coreference resolution. The dataset is designed to embody the core challenges in coreference, such as entity representation, by alleviating the challenge of low overlap between training and test sets and enabling separated analysis of mention detection and mention clustering. To strengthen the training-test overlap, we collect a large corpus of 38K documents and 12.5M words which are mostly from the vocabulary of Englishspeaking preschoolers. Experiments show that with higher training-test overlap, error analysis on PreCo is more efficient than the one on OntoNotes, a popular existing dataset. Furthermore, we annotate singleton mentions making it possible for the first time to quantify the influence that a mention detector makes on coreference resolution performance. The dataset is freely available at https:// preschool-lab.github.io/PreCo/.
Praxis der Unterscheidung (2004)

Die Leistungskraft von bestimmten Begriffen und Modellen im Vergleich zu anderen Begriffen und Modellen zeigt sich nicht nur in der Subtilität ihrer Entwicklung und argumentativen Begründung, sondern auch in dem, was sie uns einerseits zu sehen und zu verstehen und andererseits zu verändern erlauben. Zu einer vollständigen Theorie gehört, ihre Potentiale und Wirkungen für und auf die praktischen Orientierungsfragen darzustellen. Die Laws of Form sind ein Werk, in dem Theorie und Praxis eigentümlich kondensiert werden, trotz oder vielleicht gerade wegen ihres hohen Abstraktionsgrades. Die Form der Unterscheidung entfaltet theoretische und praktische Kraft. In den Laws of Form ist dieser Anspruch so ausgedrückt: „A mathematical text is thus not an end in itself, but a key to a world beyond the compass of ordinary description.“1
Comparison of the Reactions of the Rh‐Related Murine Monoclonal Antibodies BS58 and R6A (1990)

The murine monoclonal antibodies BS58 and R6A are known to recognize epitopes related to the human Rh system: neither antibody reacts with Rhnull cells and the BS58 antigen is not expressed by -D- or .D. cells. It is shown here that the numbers of BS58 and R6A antigen sites vary with Rh phenotype. Both epitopes are well represented on cells of the CDe/CDe, CDe/cDE and CDe/cde phenotypes; BS58 sites are markedly reduced on cde/cde and cDE/cde and are only just detectable on cDE/cDE cells when compared with R6A sites. The number of R6A sites per red cell ranged between 20,000 and 150,000. The evidence indicates that the BS58 epitope is not on the polypeptides carrying D or R6A, nor is it uniquely on one of the polypeptides carrying either C, c, E or e. It is suggested that the BS58 epitope is either common to all the CcED polypeptides or that it is present on a polypeptide which has not yet been identified biochemically.
3′sialyllactose and 6′sialyllactose enhance performance in endurance‐type exercise through metabolic adaptation (2023)

Human milk oligosaccharides (HMOs) belong to a group of multifunctional glycans that are abundantly present in human breast milk. While health effects of neutral oligosaccharides have been investigated extensively, a lot remains unknown regarding health effects of acidic oligosaccharides, such as the two sialyllactoses (SLs), 3'sialyllactose (3'SL), and 6'sialyllactose (6'SL). We utilized <i>Caenorhabditis elegans</i> (<i>C. elegans</i>) to investigate the effects of SLs on exercise performance. Using swimming as an endurance-type exercise, we found that SLs decrease exhaustion, signifying an increase in endurance that is strongest for 6'SL. Through an unbiased metabolomics approach, we identified changes in energy metabolism that correlated with endurance performance. Further investigation suggested that these metabolic changes were related to adaptations of muscle mitochondria that facilitated a shift from beta oxidation to glycogenolysis during exercise. We found that the effect of SLs on endurance performance required AMPK- (<i>aak-1/aak-2</i>) and adenosine receptor (<i>ador-1</i>) signaling. We propose a model where SLs alter the metabolic status in the gut, causing a signal from the intestine to the nervous system toward muscle cells, where metabolic adaptation increases exercise performance. Together, our results underline the potential of SLs in exercise-associated health and contribute to our understanding of the molecular processes involved in nutritionally-induced health benefits.

A bidirectional “αvβ3 integrin‐ERK1/ERK2 MAPK” connection regulates the proliferation of breast cancer cells (2006)

In addition to their role in cell migration and adhesion, integrins elicit a series of transduction events that regulate cell-cycle progression and apoptosis in a process known as "outside-in" signaling. A second mode of integrin regulation known as "inside-out" signaling, in which the activation of major cell transduction cascades can influence the activation status of some integrins, has also been described. Here, we have assessed the role of the extracellular signal-regulated kinase (ERK1)/ERK2, mitogen-activated protein kinase (MAPK), and phospoinositide 3-kinase (PI-3'K) signaling pathways in the expression and function of alpha(v)beta(3) integrin in breast cancer models. Pharmacological inhibition of MEK1 and MEK2 with U0126 drastically increased the levels of alpha(v)beta(3) in Heregulin (HRG)-overexpressing MDA-MB-231 cells (231/WT, 231/VEC) and derivatives transfected with the antisense orientation of the HRG-beta2 full length cDNA (231/ASPOOL, 231/AS31). Interestingly, this was related to a significant decrease of viability and of the S- and G2/M subcompartment of the cell cycle in MDA MB 231 cells in response to U0126. Furthermore, specific inhibition of the PI-3'K pathway with LY294002 also induced an increase of alpha(v)beta(3) levels but to a lesser extent. Moreover, pretreatment of MDA-MB-231 cells with U0126 antagonized the effects of small peptidomimetic alpha(v)beta(3) antagonists. Remarkably, inhibition of the PI-3'K/AKT pathway did not exert the same effects, thus suggesting that the "outside-in" as well as the "inside-out" alpha(v)beta(3)-mediated signaling goes primarily through the ERK1/ERK2 MAPK pathway in MDA MB 231 breast cancer cells. Collectively, these results strongly suggest the existence of a bidirectional molecular connection alpha(v)beta(3)-ERK1/ERK2 MAPK that would regulate breast cancer cells survival and proliferation.
Intelligent agents: an emerging technology for next generation telecommunications? (2002)

The telecommunications environment is changing its face towards an open market of information services where the vision is "information any time, at any place, in any form". Within this electronic market the aspects of service customization and instant service provision are of fundamental importance. In this context a new paradigm is gaining momentum referred to as "intelligent agents". This paper provides an overview of the emerging field of intelligent agents (IAs) by identifying their basic properties. Focusing on mobile agents, which could be considered as a specific class of intelligent agents, we identify the chances of agent technology in the context of telecommunications. We look at their potential impacts on open service architectures, intelligent communications and network management.
Nonlinear Control of Hypersonic Missiles for Maximum Target Penetration (2012)

The design of guidance and control laws for missiles traveling at hypersonic speeds is an inherently challenging task due to the fact that the system dynamics are nonlinear and highly coupled. An even more challenging task is the design of guidance laws for hypersonic missiles, which incorporates the terminal conditions to maximize target penetration. In this research, nonlinear control techniques are combined with optimal control methods to develop guidance and control laws for air-breathing hypersonic missiles in the presence of system uncertainty and external disturbances. One of the contributions of this research is detailed theoretical analysis of the performance characteristics of the proposed control design. Moreover, by including terminal constraints in the cost function, target penetration is maximized. Specifically, by minimizing angle of attack (AoA) and inertial angle of obliquity (AoO) at impact, maximum target penetration is achieved. Lyapunov-based stability analysis is utilized to prove the theoretical result, and high-fidelity numerical simulation results are provided to verify the practical performance of the proposed guidance law design.
Aged DOC is a Net Consumer of NO2: Analyses of Vehicle, Engine-dynamometer and Reactor Data (2007)

&lt;div class="htmlview paragraph"&gt;A typical diesel After-Treatment (AT) system to meet 2010 North American regulations consists of a Diesel Oxidation Catalyst (DOC) for oxidizing Hydrocarbons (HCs) and Carbon Monoxide (CO), followed by a Selective Catalytic Reduction (SCR) catalyst for NOx reduction, and a diesel particulate filter. DOCs are also used to oxidize NO in the exhaust to NO&lt;sub&gt;2&lt;/sub&gt; that substantially improves low-temperature SCR NOx reduction performance. Vehicle and engine dynamometer data under typical operating conditions show (1) engine-out NO&lt;sub&gt;2&lt;/sub&gt;/NOx can be as high as 40%, (2) DOC can reduce NO&lt;sub&gt;2&lt;/sub&gt; to NO in the presence of reductants, and (3) an aged DOC with a low CO/HC conversion can be a net consumer of NO&lt;sub&gt;2&lt;/sub&gt; over a wide range of temperatures and space velocities. Flow reactor experiments simulating diesel exhaust conditions show that DOC-out NO&lt;sub&gt;2&lt;/sub&gt; is independent of the inlet NO&lt;sub&gt;2&lt;/sub&gt;/NOx in the feed. NO&lt;sub&gt;2&lt;/sub&gt; in the feed appears to be reduced to NO prior to the oxidation of NO to NO&lt;sub&gt;2&lt;/sub&gt; which takes place when most of the reductants have been consumed. Flow reactor data also show that (1) NO&lt;sub&gt;2&lt;/sub&gt; passes through the DOC unreacted in the absence of reductants, (2) NO&lt;sub&gt;2&lt;/sub&gt; reduction may happen at the leading edge of the DOC, and hence may not be as space velocity (catalyst length) dependent as the subsequent NO oxidation, and, (3) both CO and HC individually are capable of reducing NO&lt;sub&gt;2&lt;/sub&gt;; however, HCs start reducing NO&lt;sub&gt;2&lt;/sub&gt; at a higher temperature. Thus, AT strategies (like an upstream HC trap) that limit only one of the reductant entering the DOC may not be able to minimize NO&lt;sub&gt;2&lt;/sub&gt; loss across the DOC, and engine operating strategies that generate NO&lt;sub&gt;2&lt;/sub&gt; to aid SCR NOx reduction may not be useful as long as the exhaust passes through a DOC upstream of an SCR in the presence of reductants.&lt;/div&gt;
Identification of hexose diastereomers by means of tandem mass spectrometry of oxocarbenium ions followed by neural networks analysis (2007)

The ion abundances in the tandem mass spectra of oxocarbenium ions generated from aldohexoses and ketohexoses under electrospray ionization conditions depend on their stereochemistry. The ratios of the abundances of two of the major ions m/z 85 and 91 are different in the aldohexoses and the ketohexoses. Principal component analysis (PCA) allowed visual differentiation of the hexose isomers. However, identification of an individual hexose was difficult. The data were subjected to neural network analysis (NNA) using a multilayer perceptron (MLP) model. The model was first trained using the data from the 11 hexoses and then used to identify the hexoses using fresh data acquired later. There was 100% identification of the various hexoses. The hexose units in methyl glucoside, mannoside and galactoside could also be identified accurately. The method can therefore be used for the characterization of hexose units from monosaccharides and glycosides.
OS1405 Evaluation of Stress Intensity Factor for Subsurface Flaws in the Acceptance Standards (2009)

Rules on Fitness-for-Service for nuclear power plants in JSME Code define allowable flaw depth for Class 1 vessels and piping in the Acceptance Standards. When a detected flaw is a subsurface flaw located near the component surface, the subsurface flaw should be transformed into the surface flaw. However, the inconsistency of allowable flaw depth could be seen at the transformation of subsurface flaw to the surface flaw. For the proposal of new revised Acceptance Standards, which keep a consistency of allowable flaw depth at the transformation, the effect of distance of subsurface flaw from the component surface on structural integrity of the flawed component should be evaluated. In this paper, the stress intensity factors of the subsurface flaws near the component surface were calculated to discuss the revised allowable flaw depth of subsurface flaw in Acceptance Standards. Since the estimations of stress intensity factors indicated that the stress intensity factors of subsurface flaws are not sensitive with distance from the component surface, the new revised Acceptance Standards for subsurface flaws should be only considered from the viewpoint of the consistency of allowable flaw depth at the transformation of subsurface into surface flaw.
High Resolution Raman and Neutron Investigation of Mg(BH4)2 in an Extensive Temperature Range (2010)

Raman spectra of Mg(BH(4))(2) have been measured in an extensive temperature range, from 15 to 473 K. Taking into account the high temperature conversion from the alpha to the beta phase, we have observed evident signatures of this phase transition and determined the Raman vibrational spectrum of each phase. The neutron scattering spectra of the beta phase sample were also recorded. The present experimental results have been compared to the density functional theory calculations available in the literature, and a substantial agreement has been found.
