Agent-based collaborative filtering based on fuzzy recommendations (2004)

Recommender systems intend to provide suggestions based on the opinion of several sources of information. But personalised suggestions based on past user's likes and dislikes require a distributed approach. In this way, agents may automatically collect recommendations from other agents applying personal criteria in order to determine whether an item is recommended to the user or not. The application of agent technology to the recommending problem has been tested before by researchers from the M.I.T., Univ. North Carolina, and the Spanish Research Institute. In this paper, we present a new, elegant and effective way to combine vague and subjective opinions to make recommendations using fuzzy logic. We have adapted real data on evaluations of movies (from the site MovieLens) to compare our proposal with the predecessors. The experimental results obtained show, using ROC curves and cost analysis, how our approach performs better than some other distributed collaborative filtering methods applied to provide personalised recommendations.
Production and Stabilization of Cells of <i>Bacillus popilliae</i> and <i>Bacillus lentimorbus</i> (1966)

Bacillus popilliae and B. lentimorbus grew most rapidly and to the greatest extent in aerated cultures at 30 to 32 C with oxygen absorption rates of 1 mmole of O 2 per min per liter, or above. The control of p H also increased the maximal populations attained. Media were developed which consistently produced cell populations of about 10 9 within 24 to 48 hr in aerated cultures of these two species. The acetic acid produced in highly aerated cultures was shown not to be responsible for the rapid loss of cell viability in stationary phase cultures. However, H 2 O 2 was very lethal to cells of B. popilliae , and this species is known to have the capacity to produce it. Stationary-phase cells were partially stabilized by reducing the availability of oxygen after 24 hr of incubation on a shaker, and the addition of low levels of glucose further stabilized the cells. The most stable cells were those produced in a medium in which 4% Trypticase (BBL) and 0.1% barbituric acid were incorporated. A high percentage of these cells contained refractile bodies visible under a phase microscope. Although these bodies were not heat-resistant and lacked other characteristics of endospores, cells in cultures containing them had reasonably high viability for extended periods, as compared with those in control cultures.
Simultaneous Observation of Caviton Formation, Spiky Turbulence, and Electromagnetic Radiation (1982)

Formation of density cavities, spiky turbulence, and electromagnetic radiation at the plasma frequency (${\ensuremath{\omega}}_{p}$) and its harmonics are observed simultaneously in the presence of a cold-electron beam. The electrostatic and electromagnetic frequency spectra evolve with the development of cavities.
Modified horner–emmons reaction of polymeric phosphonates: Versatile synthesis of pendant stilbene‐containing polymers (1995)

Abstract Poly[styrene‐ co ‐(diethyl vinylbenzylphosphonate)] and poly[methylmethacrylate‐ co ‐(diethyl vinylbenzylphosphonate)] were prepared and used in modified Horner‐Emmons reactions to synthesize polymers with covalently attached stilbene groups. This versatile new method allowed for the preparation of polymers with either electron‐donor (OCH 3 , CH 3 ) or electron acceptor (Br, NO 2 ) substituents on the stilbene aromatic ring. The resulting polymers were characterized by 1 H NMR, FT‐IR, UV‐visible, DSC, and size exclusion chromatography. Efficient transformation of polymeric phosphonates to the polymeric stilbene derivatives was realized. Size exclusion chromatographic analyses demonstrated that the reaction conditions have no deleterious effect on the molecular weight distribution of the various polymers that were prepared. Photochromic behavior was demonstrated for one of the derivatives. © 1995 John Wiley & Sons, Inc.
Pancreatic cancer: the role of molecular markers in diagnosis and management. (2011)

Despite an annual incidence of just 40,000 new cases per year, pancreatic adenocarcinoma (PAC) remains the fourth most common cause of cancer-related mortality in the United States, a fact indicative of the considerable diagnostic and therapeutic challenges posed by this malignancy. The availability of increasingly sophisticated molecular techniques over the last decade has intensified the search for biomarkers not only to predict outcome and response to therapy in established pancreatic malignancy but also to identify premalignant pancreatic lesions in at-risk individuals. A wealth of information regarding the complex sequence of genetic abnormalities in PAC has been gained from recent in-depth molecular analyses, and lately the role of epigenetic alterations in the development and maintenance of pancreatic carcinogenesis has been more clearly described. In addition, advances in serum proteomic methods and the collection of circulating tumor cells offer hope for the development of noninvasive techniques for biomarker discovery. At present, we are awaiting the development and validation of robust biomarkers suitable for clinical application in this disease. Herein, we discuss the current status of molecular markers in the diagnosis and management of PAC and review potential clinical applications thereof.

A versatile audio bridge for multimedia conferencing (2002)

The paper describes an audio bridge that has been built as part of a multimedia conference bridge. It connects to the public switched telephone network via an ISDN primary rate interface. A generalized mathematical representation of the basic audio bridging function in terms of a matrix multiplication is presented. Not only does it lend itself to efficient implementation on a digital signal processor, but it also allows the provision of a rich set of audio bridging services, including subconferencing, whispering, muting, monitoring, complex gain controls, and pseudo-stereo. A conference control protocol and user signaling interface is implemented which makes the full power and flexibility of the bridge accessible, manageable, and comprehendable to users. A set of privacy principles is formulated and an enforcing mechanism is described in order to prevent abuse of the system. Two graphical user interfaces have been built, one providing centralized control of the bridge, the other integrated into the "Rapport" multimedia conferencing system. The bridge is controlled by a general purpose processor with both LAN and WAN interconnectivity, thus the bridge can be controlled by applications running elsewhere. It can also easily be programmed to implement new bridging services. Apart from the basic audio bridge described, the multimedia bridge which it is part of also performs data bridging, video bridging, and other audio bridging functions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The sinusitis cycle (1990)

Recent discoveries make it necessary to reevaluate many of the traditional assumptions concerning sinusitis. Within the past 10 years, investigators have detailed the pathophysiology of sinusitis. Occlusion of the sinus ostia initiates the sinusitis cycle; untreated, this leads to chronic sinusitis. Anatomic abnormalities also predispose the patient to chronic sinusitis because of ostial blockage. Investigators have identified and detailed the prevalence of both aerobic and anaerobic environments within the sinuses, demonstrating that ostial blockage creates an ideal culture medium within the sinus. Keeping the ostial passageways open is essential to allow reversal of the sinusitis cycle, especially in the presence of predisposing factors.
High-speed quantum well and quantum dot lasers (1998)

The characteristics of high-speed quantum well and quantum dot lasers are described. It is seen that substantial improvements in small-signal modulation bandwidth are obtained in both 1 micrometers (48 GHz) and 1.55 micrometers (26 GHz) by tunneling electrons directly into the lasing subband. In quantum dots the small-signal modulation bandwidth is limited by electron-hole scattering to approximately 7 GHz at room temperature and 23 GHz at 80 K.
Automatic parameter tuning for image denoising with learned sparsifying transforms (2017)

Data-driven and learning-based sparse signal models outperform analytical models (e.g, wavelets), for image denoising, but require careful parameter tuning to reach peak performance. In this work, we provide a solution to the problem of parameter tuning for image denoising with transform sparsity regularization. We show that by viewing a learned sparsifying transform as a filter bank we can utilize the SURELET denoising algorithm to automatically tune parameters for an image denoising task. Numerical experiments show that combining SURELET with a learned sparsifying transform provides the best of both worlds. Our approach requires no parameter tuning for image denoising, yet outperforms SURELET with analytic transforms and matches the performance of transform learning denoising with hand-tuned parameters.
Time‐based manufacturing logistics (1995)

Proposes that, due to the changing market, companies can no longer work with the logistic systems of the past but must develop new logistic concepts, logistic management and control systems to support the new concepts. Discusses the importance of order penetration point (OPP) within the development of time‐based management and control systems. Concludes that creativity in product development, production and distribution must be based on strong modern logistical foundations to survive in the competitive market.
Chromosomes Can Congress to the Metaphase Plate Before Biorientation (2006)

The stable propagation of genetic material during cell division depends on the congression of chromosomes to the spindle equator before the cell initiates anaphase. It is generally assumed that congression requires that chromosomes are connected to the opposite poles of the bipolar spindle ("bioriented"). In mammalian cells, we found that chromosomes can congress before becoming bioriented. By combining the use of reversible chemical inhibitors, live-cell light microscopy, and correlative electron microscopy, we found that monooriented chromosomes could glide toward the spindle equator alongside kinetochore fibers attached to other already bioriented chromosomes. This congression mechanism depended on the kinetochore-associated, plus end-directed microtubule motor CENP-E (kinesin-7).

A third order distributed feedback surface grating is fabricated in the top emitter AlGaAs confining layers using soft photocurable nanoimprint lithography. The device produces continuous wave laser operation with a peak wavelength λ=959.75 nm and threshold current IB=13 mA operating at −70 °C. For devices with cleaved ends a sidemode suppression ratio &gt;25 dB has been achieved.
Metered-Dose Inhaler Adherence in a Clinical Trial (1992)

We studied patterns of inhaler usage in a sample of participants from two centers in the Lung Health Study clinical trial. The inhaler, containing either ipratropium bromide or a placebo, was prescribed to be taken as two inhalations three times daily. For 4 months we recorded adherence by both self-report (n = 95) and canister weight change (n = 70). We compared these results with data obtained from a microprocessor monitoring device, the Nebulizer Chronolog (NC), which records the date and time of each inhaler actuation. Seventy-three percent of the participants reported using the inhaler an average of three times daily; however, NC data showed that only 15% of the participants actually used the inhaler an average of 2.5 or more times per day. Canister weight overestimated adherence because only 62% of the NC sets contained the prescribed two actuations. Fourteen percent showed a pattern of actuation of their inhalers more than 100 times in a 3-h interval. We interpret this usage pattern to reflect deliberate emptying of inhalers to appear to be in good compliance with the prescribed program. We conclude that self-report and weighing of inhaler canisters overestimate adherence to the prescribed regimens. Furthermore, a substantial number of monitored inhaler users appear to deliberately dump their medication prior to follow-up visits.
Signaling of the Cardiotrophin-1 Receptor (1997)

Cardiotrophin-1 (CT-1) is a recently isolated cytokine belonging to the interleukin-6 cytokine family. In the present study we show that CT-1 activates its receptor expressed at the surface of a human neural cell line by recruiting gp130 and gp190/leukemia inhibitory factor receptor beta, as shown by analyzing their tyrosine phosphorylation level. Neutralizing antibody directed against gp130 and reconstitution experiments performed in the COS-7 cell line demonstrate that gp130-gp190 heterocomplex formation is essential for CT-1 signaling. Analysis of the subsequent activation events revealed that CT-1 induces and utilizes Jak1-, Jak2-, and Tyk2-associated tyrosine kinases, which are in turn relayed by STAT-3 transcription factor. Cross-linking of iodinated CT-1 to the cell surface led to the identification of a third alpha component in addition to gp130 and gp190, with an apparent molecular mass of 80 kDa. Removal of N-linked carbohydrates from the protein backbone of the alpha component resulted in a protein of 45 kDa. Our results provide evidence that the CT-1 receptor is composed of a tripartite complex, a situation similar to the high affinity receptor for ciliary neurotrophic factor.
Polylactides—Chemistry, Properties and Green Packaging Technology: A Review (2010)

Polylactide (PLA), a biodegradable aliphatic polyester, has been studied extensively for its wide applications in various fields from food packaging to interior materials for automobiles. One of PLA's advantages is that the raw material, lactic acid can be derived from renewable resources, which makes PLA very attractive for the packaging and considered as green packaging. Although, the cost of PLA is relatively higher compared to petroleum based packaging materials and it is predicted that the price will go down after commercial success of the process. This paper presents a review on polylactide with focus on its chemistry, synthesis, properties, and applications. Plasticization effect on PLA, sorption isotherm and mechanical properties of PLA based packaging materials have been discussed. PLA/layered organo nanocomposites exhibit significant improvement in mechanical, thermal, optical, and physicochemical properties over pure PLA. This review includes brief overview of PLA based nanocomposite, their mechanical properties, potential as packaging materials for industrial usage and their environmental implications.
Computational Theory of Perceptions (2014)

This paper aims to bring out the significant contribution of the Professor Lotfi A.Zadeh,”the father of Fuzzy Logic” in the field of Soft Computing. The computational Theory of Perceptions (CTP) deals with the automated processing of human knowledge expressed in Natural language. The development of computational system based on the Computational Theory of Perceptions is a challenging task that requires taking into account knowledge extended to several scientific disciplines such as Fuzzy Logic, Linguistics and Software Engineering. The Computational Theory of Perceptions is based on the methodology of computing with words. In CTP words play the role of labels of perceptions and more generally, perceptions are expressed as propositions in a natural language. Computing with words (CW)based techniques are generally used to translate propositions expressed in a natural language into Generalized Constraint Language (GCL).
Studies of Helical Aggregates of Molecules. II. The Sense of Twist in the Fibrous Aggregates from the Alkali Metal Soaps of Optically Active 12-Hydroxystearic Acid (1970)

Abstract Under an electron microscope, it was observed that the alkali metal soaps of 12-d(or l)-hydroxystearic acid separated out twisted fibers from various solutions. A symmetrical relationship regarding the sense of the twist was found between the soap fibers of the d-enantiomer and those of the l-enantiomer. In the case of the soap fibers of the d-enantiomer, the sense of twist was right-handed for the Li soap and left-handed for the Rb and Cs soaps. The Na- and the K- soap fibers produced both right-handed and left-handed fibers. A solvent effect with respect to the sense of twist was found for the fibers of the free acid and its Li soap. The cause of the twisting was discussed in connection with the structure and the growth process of the soap crystal.
Development of an Exhaust Driven Turbine-Generator Integrated Gas Energy Recovery System (TIGERS<sup>®</sup>) (2014)

The mechanical design for this application is particularly challenging for a number of reasons. The turbine is capable of rotating the shaft at speeds greater than its critical rotating limit. Rolling element grease filled bearings are used to allow application flexibility; these have an operating temperature limit of 200°C. The exhaust gas can reach temperatures greater than 900°C in spark ignition applications, whereas the turbine upper functional limit is 850°C. The power electronics are integrally mounted in the machine and have a maximum thermal operating limit of 120°C.</div><div class="htmlview paragraph">Considering that TIGERS is expected to harvest energy from the exhaust gas it is essential that it not only survives in this harsh environment, but it must also produce work with no adverse impact on vehicle performance or fuel efficiency.

Enzyme-immunoassay of human alpha-fetoprotein. (1978)

An enzyme-immunoassay for the quantitation of human alpha-fetoprotein was developed employing the so-called sandwich method using filter paper discs as a solid-phase. Filter paper discs were activated with cyanogen bromide and the specific antibody to alpha-fetoprotein was covalently bound to the discs. The enzyme-labeled antibody was prepared by coupling the antibody to alkaline phosphatase with the aid of glutaraldehyde. The antibody-coated filter paper discs were incubated with the samples containing alpha-fetoprotein, which was bound to the discs, then the discs were incubated with the enzyme-labeled antibody solution. The enzyme activity bound on the discs was then measured, and was found to be proportional to the amount of alpha-fetoprotein in the sample. The present method provided an accurate measurement for human alpha-fetoprotein in test serum in a range of 40 approximately 1,000 ng/ml. The sensitivity was almost comparable to that of radioimmunoassay. alpha-Fetoprotein levels in the normal and patient sera tested with this method were in good agreement with the values obtained by the radioimmunoassay technique.
Simulation and analysis of V-22 tiltrotor aircraft forward flight flowfield (1995)

The flowfield about a wing-fuselage-nacelle configuration of the V-22 tiltrotor aircraft at a freestream Mach number of 0.345 and angles of attack ranging from 7 to 16 deg is simulated by using a multizone, thin-layer NavierStokes method. The flow conditions yield a Reynolds number of 18.2 x 10 based on the wing chord for flight at an altitude of 10,000 ft. Major flow features including the three-dimensional flow separation from viscous-vortex interactions observed experimentally are captured by the simulation. The massive separation from the wing and the fore fuselage-sponson region for flows at high angles of attack creates free vortices that pass by the rear fuselage region, including the tail section of the aircraft.
Antiviral, antibacterial and antitumor activity of the hydrazide and the ethyl ester of 2,2'-anhydro-1-(beta-D-arabinofuranosyl)-orotic acid. (1980)

It has been demonstrated that the hydrazide and the ethyl ester of 2,2'-anhydro-1-(beta-D-arabinofuranosyl) orotic acid inhibit selectively the multiplication of some DNA-containing viruses (PsRV, VV, AdV5), suppress the growth of E. coli and St. aureus in vitro and exhibit an antitumor effect with Lewis lung carcinoma and sarcoma 298.
