Virtual annotation: Verbal communication in virtual reality (1993)

This paper describes a system that was developed to explore communication in Virtual Reality. The system offers a simple and powerful method to embed verbal communication in simulations and visualizers by means of voice annotation. Our prototype already demonstrates that the addition of verbal communication opens up a range of new uses for virtual environments. A similar voice annotation facility is easily added to existing visualizers and simulations, and it enables reading, writing, and communicating.
<title>In-process drilling-states monitoring in machining centre by time series analysis</title> (1993)

Monitoring of the cutting process is one of the most crucial and difficult problems in unmanned machining technology. In this paper, the effects to the thrust and the torque in drilling by some abnormal cutting states have been investigated. Experiments show that the dynamic components of the thrust and the torque provide useful information for identifying different tool failures. Reasonable explanations have been given for the phenomena from physical mechanisms. A mathematical model for the dynamic cutting process was proposed and some problems about the estimation of the time series AR(n) model were also discussed. After having compared several defined monitoring parameters, a new inprocess signal processing method, `adaptive variance-residual recursive algorithm,' based on least squares theory has been suggested with which signal signatures of cutting states can be extracted effectively. It bears the advantages of rapid response, less amount of calculation, and easy to set deterministic thresholds. The in-process monitoring system developed shows a bright prospect in practical application.
PREPARATION OF CARBON ELECTRODES MODIFIED WITH POLY(MERCAPTOHYDROQUINONE)S AND THEIR FUNCTIONS AS pH SENSOR (1986)

Abstract Carbon fiber electrodes (CFE) were modified with either a poly(mercaptohydroquinone) film or a poly(methylmercaptohydroquinone) film by means of electrochemical oxidation. The modified CFE thus prepared showed an excellent Nernstian response to H+ ion over the pH range from 2 to 9.
Latin Hypercube Sampling of Gaussian Random Fields (1999)

Following the method of Stein, this article shows how a Latin hypercube sample can be drawn from a Gaussian random field. In a case study the efficiency of Latin hypercube sampling is compared experimentally to that of simple random sampling. The model outputs studied are the mean and the 5- and 95-percentile of the areal fraction where point concentration of zinc in the topsoil exceeds a given threshold. The Latin hypercube sampling procedure slightly distorts the short-distance correlation, and in an artificial example, it is shown that this distortion is modest for small samples and vanishes for large samples.
The Risk of Tuberculosis in Patients with Rheumatoid Arthritis Treated with Tumor Necrosis Factor-α Antagonist: A Metaanalysis of Both Randomized Controlled Trials and Registry/Cohort Studies (2015)

This study demonstrated a significant increase in TB risk in patients with RA treated with TNF-α antagonists; among them, ETN is least likely to cause active TB. The study also proposes the necessity of LTBI prophylaxis in patients with RA.
Decedents' Estates - Wills - Doctrine of Dependent Relative Revocation - May Not Be Applicable in Arkansas (1981)

His wife Verna contended that he had died intestate, while his brother, Arthur, urged that a 1978 will be admitted to probate.Arthur testified that the 1978 will provided him a devise of $30,000 with Verna to get the rest of the estate.I One witness testified that Woodrow had asked him how to effectively destroy his will.Another testified to hearing Woodrow say, the day before he died, that he had torn up his will and had to "get one made out." 2 He added that Woodrow at one time had said that his brothers "had all they needed."Verna testified that her husband intended to make a new will quite a bit different from the destroyed one, but died suddenly before doing so. 3 She testified that he tore and burned the 1978 will because of conversations with his family which indicated that were he to die Verna would get nothing. 4 The Cleburne County Probate Court found that Woodrow had destroyed the 1978 will with the intention of making a new one.The court then applied the doctrine of dependent relative revocation and admitted the 1978 will to probate. 5 On appeal Verna Larrick argued that the lower court had erred in applying the doctrine of dependent relative revocation since the doctrine was not law in Arkansas.In the alternative, she urged that there was not sufficient evidence to rebut the presumption that Woodrow intended to revoke the will in question. 6 The Arkansas Court of Appeals reversed and remanded the decision of the probate court, finding that the deceased's will had been revoked and that he therefore died intestate. 7 The court left a strong implication that in Arkansas, application of the doctrine of dependent relative revocation may be precluded by existing Arkansas stat-1.
Polymerizations at High Pressures (1984)

Abstract Pressure is an element in the control of natural phenomena, as is temperature. The investigation of the role of pressure must be understood so that we may control and use pressure effectively.
Authorization model of SSO for a distributed environment based on the attributes (2012)

With the distributed application of computer technology and continuous development, more and more service systems provide us with information services, each service needs to have permission to verify this general requirement. At the same time, based on dynamic, loosely coupled environment, the business process will involve more than one ISP so that users need to face the trouble of multiple logins to complete it. Traditional users single sign-on (SSO) mechanism have solved the trouble of users' multiple logins to complete the business [1]. However, the traditional authorization is based on the role of request access to the entity of resources, either directly or indirectly assigned to the login access to these entities or log on roles, but these are unable to meet current validation requirements service, for example: we need to verify the status of the entities, the balance, consumer grade and so on [2]. Therefore, this paper based on an open source framework, called CAS; develops a model of SSO Service authorization under distributed environment [4]. It uses the XACML to achieve an attribute based access control (ABAC) [3], this model is characterized by the following three points: 1. complete SSO under distributed environment [4], 2. Able to verify data sources from different databases when completing SSO; 3. Able to use property-based verification for more accurate authorization after authentication. These make access control to be more flexible, a wider range of usage and a finer granularity of control.
Development of Active Antimicrobial Fiber‐Based Chitosan Polysaccharide Nanostructures using Electrospinning (2008)

Abstract The electrospinning technology opens up enormous possibilities for the implementation of bio‐based materials and food hydrocolloids in numerous applications. In this context, chitosan is a sustainable, biocompatible, biodegradable, antimicrobial and non‐toxic polysaccharide of great relevance in many fields of application. Because of its abundance in nature and excellent biocompatibility, the cationic polysaccharide chitosan is a very promising polymer for producing functional nanofibers. Although the material has good physicochemical properties, the electrospinning of the polymer is far from easy. In the current study, the effect of an unprecedented number of parameters (including solvent nature, polymer origin, molecular weight and spinning conditions) on morphology is reported. The work also aims to ascertain the antimicrobial properties of the generated biofibers of chitosan and relate them to its chemical structure. Finally, a new route is provided to generate chitosan based nanoporous structures starting from blends of chitosan and polylactic acid.
A New Definition-Use Net Generator for Ada 2012 Programs (2017)

Definition-Use Net (DUN) is a graph-theoretical concurrent program representation that is very useful in software development activities such as program dependence analysis, testing, debugging, and complexity measuring. It is an arc-classified digraph having vertices representing information about definitions and/or uses of the values of variables, and inter-process synchronization and communication, and arcs representing deterministic or nondeterministic control ows between vertices. For capturing Definition-Use Nets for Ada 2012 programs, we developed an Asis-based DUN generator for Ada 2012 programs. This article presents an informal explanation for DUNs of Ada 2012 programs and shows some example DUNs of Ada 2012 programs generated by our DUN generator
Walter Pater (1991)

This chapter examines Walter Pater's career during a time when literary critics faced a serious crisis of authority. It evaluates Pater's first book, Studies in the History of the Renaissance (1873) as well as the criticisms it received. It presents a spectrum of quoted material which in fact comprises a large proportion of the novel's overall content. It notes that Pater's principal intellectual concern was to engage with the concepts of textual and historiographical authority. It discusses how Pater was attempting to undertake the kind of critical enterprise which Grant Allen had insisted on a decade earlier. However, this was no longer possible. In Marius the Epicurean and Plato and Platonism, Pater was trying to write works in which and for which authority existed in the author alone.
T Cell Receptor Fused to CD3ζ: Transmembrane Domain of CD3ζ Prevents TCR Mis-Pairing, Whereas Complete CD3ζ Directs Functional TCR Expression (2011)

TCR gene therapy represents a feasible and promising treatment for patients with cancer and virus infections. Currently, this treatment rationale is hampered by diluted surface expression of the TCR transgene and generation of potentially self reactive T-cells, both a direct consequence of mis-pairing with endogenous TCR chains. As we reported previously (Gene Ther 16:1369 Here, we set out to minimize the content of CD3 in TCR: , specific for MAGE-A1/HLA-A1, without compromising TCR pairing and function. Domain-exchange and 3D-modeling strategies defined a set of minimal TCR: variants, which, together with a murinized and cysteine-modified TCR (TCR:mu+cys), were tested for functional TCR expression and TCR pairing. Our data with Jurkat T cells show that the CD3 transmembrane domain is important for cell-surface expression, whereas the CD3 intracellular domain is crucial for T-cell activation. Notably, inability of TCR: to mis-pair was not observed for TCR:mu+cys, which depended exclusively on the transmembrane domain of CD3 and could not be recapitulated by a limited number of structurally defined CD3 transmembrane amino acids. The extracellular CD3 domain was dispensable for TCR: 's ability to prevent TCR mis-pairing, bind pMHC and mediate NFAT activation. In primary human T cells, however, minimal TCR: without CD3 's extracellular domain but not TCR: nor TCR:mu+cys revealed compromised cell surface expression and T cell function. Taken together, our study demonstrates that CD3 's transmembrane domain dictates TCR: 's inability to TCR mis-pair, but only TCR coupled to complete CD3 and not its minimal variants were functionally expressed in primary T cells.
Ginger inhibits cell growth and modulates angiogenic factors in ovarian cancer cells (2007)

Ginger inhibits growth and modulates secretion of angiogenic factors in ovarian cancer cells. The use of dietary agents such as ginger may have potential in the treatment and prevention of ovarian cancer.
Experimental Evidence Concerning Two Different Kinds of Smectic <u>C</u> to Smectic <u>A</u> Transitions (1977)

Abstract Experimental evidence is presented indicating that there are two distinctly different kinds of smectic C to smectic A transitions. The first type is second order with zero tilt in both phases, the second type is first order with a non-zero tilt angle in both phases. The model for the second type of transition is an “uncoupling” of the tilt directions of adjacent layers in the smectic -A phase.
Shift-Invariant Optical Associative Memories (1987)

Shift invariance in the context of associative memories is discussed. Two optical systems that exhibit shift invariance are described in detail with attention given to the analysis of storage capacities. It is shown that full shift invariance cannot be achieved with systems that employ only linear interconnections to store the associations.
A Survey on Dynamic Spectrum Access Techniques in Cognitive Radio (2012)

Wireless networks are characterized by fixed spectrum policy. With increasing demands for wireless communication efficiently using the spectrum resources has become an essential issue. Cognitive radio is a form of wireless communication which is used to sense the spectrum and find the free spectrum. It is used by unlicensed users without causing interference to the licensed user. Cognitive radio with the dynamic spectrum access is key technology which provides the best solution by allowing a group of Secondary users to share the radio spectrum originally allocated to the primary users. Dynamically accessing the unused spectrum is known as dynamic spectrum access (DSA) which becomes a promising approach to increase the efficiency of spectrum usage. In this paper, DSA models are discussed along with different methods such as game theory based method, a measurement-based model, network coded cognitive control channel, Markovian Queuing model, the Delay performance of threshold policies, fuzzy logic based method and spatio-temporal spectrum management model.
Effects of glucagon and insulin on lipolysis and ketogenesis in sheep. (1976)

The hepatic and portal productions of acetoacetate and beta-hydroxybutyrate and lipolysis were studied in normal and insulin-controlled alloxan-diabetic sheep. Since hyperinsulinemia is associated with glucagon administration, the latter group of sheep were used to maintain constant plasma insulin levels. After control values were obtained glucagon was infused intraportally at 90 mug/hr for two hours. The ketone body production by portal drained viscera was not significantly affected by glucagon. In alloxanized sheep, glucagon significantly (P less than 0.01) increased net hepatic production of acetoacetate (from -0.54 +/- 0.08 to 0.46 +/- 0.07 g/hr). Lipolysis also increased. However, in the normal sheep, hyperinsulinemia prevented any stimulatory effect of glucagon on hepatic ketogenesis and lipolysis. Therefore, while glucagon appears capable of stimulating ketogenesis andlipolysis, these effects are readily suppressed by insulin.
Aggregation States of Asphaltenes: Evidence of Two Chemical Behaviors by <sup>1</sup>H Diffusion-Ordered Spectroscopy Nuclear Magnetic Resonance (2009)

The mean molecular weight and particle size of asphaltene aggregates extracted from Buzurgan feedstock have been evaluated by measuring the diffusivity by means of 1H diffusion-ordered spectroscopy (DOSY) nuclear magnetic resonance (NMR). This technique, recently applied in the petroleum industry, appeared as a key tool to investigate the behavior of asphaltenes diluted in toluene over a wide range of concentrations (from 0.01 to 15 wt %). The results show that the diffusivity is highly dependent upon solute concentration. Indeed, interactions occurring in dilute systems differ from interactions occurring in the semi-dilute regime. In the dilute regime (below 0.25 wt %), physical characterization of the nanoaggregates detected by 1H DOSY NMR could be achieved. An average molecular weight of roughly 6900 g mol−1 (taken at the highest diffusion peak and given as a polystyrene equivalent) with a range of 1500−85000 g mol−1 was obtained, while a mean radius of 15.6 Å was determined from the solute diffusivity at infinite dilution [D∞asp ∼ (2.4 ± 0.1) × 10−10 m2 s−1 for Buzurgan asphaltenes]. Average masses (Mn and Mw) were also calculated from DOSY NMR data and compared to results obtained from size exclusion chromatography (SEC) analyses. We also used DOSY NMR techniques to investigate the molecular dynamics of asphaltenes. A concentration of 0.25 wt % was found to represent the onset of the aggregation process. We believe DOSY NMR allowed us to observe the beginning of aggregation in phase transition. The asphaltene system is very polydisperse. At low concentrations, it is a polydisperse diluted system, but increasing the solute concentration induces a distinction of different aggregates, presenting various sizes in a macroscopic homogeneous phase. When the distinction occurs, there is a zone that is richer in high molecular weight aggregates of asphaltenes, and as a result, a second zone is impoverished in high molecular weight aggregates. In a microscopic point of view, there is a difference in nano or macroaggregate concentration, whereas in a macroscopic point of view, an average density is observed. For the first time, a clear separation between two families of aggregates of asphaltenes is presented in the diffusion dimension for concentrations higher than 3 wt %. 1H DOSY spectra and diffusion profiles confirm these results. The key point of this study resides in the detection and presentation of two classes of aggregates of asphaltenes achieved for concentrated solutions, without any assumption concerning the composition of the mixture.
Jammin' on the Web - a new Client/Server Architecture for Multi-User Musical Performance. (2000)

This paper describes a software system called the Tran-sJam Server that allows several musicians to log into an Internet web site and perform music together.The system is general purpose so programmers can develop web based applications in a variety of styles.A single server can support several different applications simultaneously, for example musical applications, games, or conferencing.A simple protocol allows clients to enter a lobby, obtain a list of active sessions, join a session, and then exchange information with other members of the session.Server operations such as object locking and data broadcasting allow users to create and edit shared data objects without corrupting them.The server is written in 'C' and runs on PC or Unix based hosts with low overhead.Client applications are typically written in 'C' or Java.A chat feature is available which allows musicians to discuss musical strategies and to interact socially.The Java version can be used with a number of audio APIs including JSyn, JMIDI, or SUN's new JavaAudio.Applications must be designed to work well despite Internet latencies.Examples include drum boxes, algorithmic music generators, or "ambient" synthesis environments.
Atomic structure and doping of microtubules (1993)

The atomic and electronic structures of microtubules of graphitic carbon have been investigated by ab initio molecular dynamics. Fully optimized atomic structures of two microtubules, a reflection symmetric and a chiral, are found to differ little from their ideal, graphite-derived geometries. Both are semiconductors with direct band gaps at the \ensuremath{\Gamma} point and along the \ensuremath{\Delta} direction, respectively. It is shown by direct calculations in large supercells that substitutional N and B dope microtubules n and p type.
Flexible Fiberoscopy of Urinary Conduits (1976)

During the last 2 years 7 patients with intestinal urinary conduits, exhibiting symptoms of gross hematuria and ureteral stricture or other difficulty with the conduit, were examined with flexible fiberoptic endoscopes. The entire lumen of the intestinal conduit, all urinary-intestinal anastomoses and the bladder of 1 patient were visualized successfully. Retrograde pyelography was performed on 2 patients. In 4 of 7 patients we were able to demonstrate abnormalities that were not demonstrable by any other method.
Spin-Polarized Vacuum Tunneling into the Exchange-Split Surface State of Gd(0001) (1998)

Spin-polarized tunneling is demonstrated on Gd(0001) thin films using ferromagnetic probe tips in a low-temperature scanning tunneling microscope. The magnetic field dependent asymmetries in the differential tunneling conductivity are found at bias voltages which correspond to the energies of the spin components of the exchange-split Gd(0001) surface state. Maps of the spatial variation of the asymmetry reveal the magnetic structure of Gd(0001) thin films with a lateral resolution better than 20 nm. It is found that magnetic tip coatings thicker than 100 monolayers Fe may modify the sample domain structure due to the stray field of the tip.
Microfluidics‐based electrospray ionization enhances the intrasource separation of lipid classes and extends identification of individual molecular species through multi‐dimensional mass spectrometry: development of an automated high‐throughput platform for shotgun lipidomics (2008)

Herein, we exploit the use of microfluidics and optimized Taylor cones for improved intrasource separation/selective ionization of lipid classes during electrospray ionization. Increased differential ionization of multiple phospholipid classes was achieved through microfluidics with chip-based ionization resulting in substantial enhancement of intrasource separation/selective ionization of phospholipid classes in comparison to the conventional ion source. For example, using myocardial lipid extracts, 3-fold improvements in intrasource separation/selective ionization of myocardial phospholipid classes were routinely realized in the negative-ion mode in the absence of LiOH or other basic modifiers in the infused sample solutions. Importantly, the relative ratios of ions corresponding to individual molecular species in each lipid class to a selected internal standard from myocardial extracts were nearly identical between the chip-based interface and the syringe-pump-driven capillary interface. Therefore, quantitation of individual lipid molecular species directly from biological extracts through comparisons with internal standards in each lipid class was readily accomplished with an accuracy and dynamic range nearly identical to those documented using the well-established direct syringe-pump-driven capillary interface. Collectively, the use of microfluidics and robotic sample handling substantially enhances intrasource separation of lipids in comparison to routine capillary interfaces and greatly facilitates the use of multi-dimensional mass spectrometry using shotgun lipidomics, thereby providing an automated and high-throughput platform for global analyses of cellular lipidomes.
Development of Low-Carbon, Copper-Strengthened HSLA Steel Plate for Naval Ship Construction (1990)

Abstract : Modern warships designs require an increased utilization of high strength, alloy steel plate for weight reduction, stability, increased payload, and increased mobility. Naval ship structures are subjected to a complex spectrum of loads and service environments, and the structural steels and welding materials used in hull fabrication must demonstrate high fracture toughness for these extreme service conditions. The welding of HY-series high strength steels, traditionally used in Navy ship construction, requires a number of fabrication controls to prevent weld cracking, which result in high fabrication costs. The Navy initiated the HSLA steel program with a goal of reducing ship-building costs. This report describes the development and certification of Cu-strengthened HSLA steels which are weldable with reduced parameter control (particularly preheat,), and provide high strength, high toughness, and high quality weldments. HSLA-80 steel (MIL-S-24645) was certified for use in ship construction after an extensive program demonstrated that the low carbon, copper precipitation strengthened steel met the performance requirements of HY-80 steel, but was readily weldable without preheat. Lower fabrication costs and higher productivity in construction were realized. (jes)
