Synthesis of nonequilibrium reactive distillation processes by MINLP optimization (1994)

Abstract A mixed integer nonlinear programming (MINLP) model is presented for synthesizing reactive distillation columns when chemical reaction equilibrium cannot be assured. The MINLP minimizes the total annual cost subject to a rigorous tray‐by‐tray model. The solution of this MINLP yields the optimal number of trays, the optimal feed rates, and the optimal feed tray locations. The liquid holdup per tray, the reflux ratio, and the temperature and composition profiles within the column are optimized as well. The MINLP is solved using generalized Benders decomposition, and the technique is illustrated with ethylene glycol synthesis.

Eastern Art Annual. Volume III (1932)

UNDER the continued able editorship of Messrs. Warner and Jayne, Eastern Art, Vol. III, has recently made its appearance. A generous number of illustrations and a liberal use of Chinese characters at once agreeably impress the reader with the fact that those who are responsible for the publication have succeeded in bringing out a volume even worthier than the preceding issues.
A fast scan-line algorithm for rendering parametric surfaces (1979)

An algorithm for rendering shaded pictures of parametric curved surfaces is presented. The algorithm recursively subdivides each surface element on the basis of its screen-space parametric curvature until it is sufficiently close to bilinear to be scan-converted by conventional polygon rendering techniques. The mathematical basis chosen to carry out the subdivision process yields the curvature criterion as a coefficient so that the tests for termination of the subdivision process are extremely simple. In addition, a surface is subdivided only in the parametric direction in which its curvature deviates from the tolerance. The algorithm incorporates a very simple solution to the problem of separations between sibling subpatches.
State of the art in sensor technologies for sewer inspection (2002)

This paper reviews the state of the art in sensors and automated inspection devices for enhanced sewer inspection. Efficiency, safety, environmental, and legislative concerns have made inspection and assessment of communal sewers a central issue to water and sewerage companies. Nowadays, the standard sewer inspection system is based on a wheeled platform on which a closed circuit television (CCTV) camera is mounted. One of the disadvantages of camera inspection systems is that they can only detect a small proportion of all possible damage in a sewer. The inspection outcome of such systems relies not only on the quality of the acquired images, but also on the off-line. recognition and classification conducted by human operators. In consequence, CCTV-based platforms are frequently not effective. Infrared, microwave, optical, and ultrasonic-based sensors have been proposed to complement the existing CCTV-based approach and to improve inspection results. New inspection devices employing multiple sensors and being capable of carrying out remote sewer inspection tasks are under research.
Effect of heat and H<inf>2</inf> gas on the photo-darkening of Yb<sup>+3</sup> fibers (2006)

Heating a photo-darkened ytterbium fiber causes a recovery in spectral transmission to the pre-darkened state. Exposure to H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> at high temperatures causes a permanent change in the visible transmission identical to that caused by photo-darkening.
Selective Hypothermic Perfusion of Canine Brain (1996)

A method for selective brain cooling by profound hemodilution with cold Ringer's lactate solution was previously reported in 1992. We recently modified this technique by combining it with an ultrafiltration and rewarming circuit between the left jugular vein and the inferior vena cava. We used 12 beagle dogs to study the efficacy of selective cerebral hypothermia induced by this modified technique. The brain temperature decreased to 28 degrees C within 5.4 +/- 2.7 minutes and to 20 degrees C within 15.5 +/- 9.4 minutes. The lowest brain and rectal temperatures were 17.0 +/- 1.8 degrees C and 32.1 +/- 2.2 degrees C, respectively. All animals survived in good condition without evidence of neurological deficits until they were killed at 10 weeks. Histological examination of the brains with 2,3,5-triphenyltetrazolim chloride demonstrated no evidence of ischemic lesions, and even in the hippocampus, there was no evidence of ischemic neuronal damage.
Leakage Flux Distribution in the Simulated Environment (2012)

Current research about voltage leakage involves investigation of the effects of leaked voltage and current on humans through simulated environments and dummies. Electrocution results from leaked current when electricity flows through the body as a result of potential difference. Research that analyzes actual electrocution is insufficient because of the danger from leaked voltage present in the leakage area. This thesis analyzes magnetic flux density from current around a leak to investigate the distribution of current. The authors used a simulated environment to investigate electrocution accidents that frequently occur during floods through leakage along metal surfaces, and evaluated the distribution of leaked magnetic flux.

Influence of growth of <i>Streptomyces fradiae</i> on pepsin-HCl digestibility and methionine content of feather meal (1971)

Feather meal, fermented by a methionine-excreting mutant of Streptomyces fradiae in the presence of a mineral salts solution and glucose, was 90% digestible in acidified pepsin solution as compared with 65–70% for unfermented meal. Feeding trials with chicks, however, indicated that no significant difference in nutritional value existed between fermented and unfermented meal. Lack of product acceptability may have been partly responsible.
SER of Threshold-Based Hybrid Selection/Maximal-Ratio Combining in Correlated Nakagami Fading (2005)

The average symbol-error rate of threshold-based hybrid selection/maximal-ratio combining (T-HS/MRC) with correlated Nakagami-m fading channels is obtained for positive integer values of fading parameter m for a special correlation structure. An accurate approximate analysis of T-HS/MRC in arbitrarily correlated Nakagami-m fading channels is presented by using a Green matrix approximation. The derivation allows different M-ary linear modulation schemes. We illustrate our methodology using M-ary phase-shift keying as an example.
Articulation management for intelligent integration of information (2001)

When combining data from distinct sources, there is a need to share meta-data and other knowledge about various source domains. Due to semantic inconsistencies and heterogeneity of representations, problems arise in combining multiple domains when the domains are merged. The knowledge that is irrelevant to the task of interoperation will be included, making the result unnecessarily complex. This heterogeneity problem can be eliminated by mediating the conflicts and managing the intersections of the domains. For interoperation and intelligent access to heterogeneous information, the focus is on the intersection of the knowledge. An algebra over domain is proposed which uses articulation rules to support disciplined manipulation of domain knowledge resources. The objective of a domain algebra is to provide the capability for interrogating many domain knowledge resources. The algebra formally supports the tasks of selecting, combining, extending, specializing, and modifying components from a diverse set of domains. The paper presents a domain algebra and demonstrates the use of articulation rules to link declarative interfaces for Internet and enterprise applications. In particular, it discusses the articulation implementation as part of a production system capable of operating over the domain described by the interface description language (IDL) of objects registered in multiple CORBA servers.

Performance Characteristics of Four High-Throughput Immunoassays for Detection of IgG Antibodies against SARS-CoV-2 (2020)

The role of serologic testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in both the clinical and public health settings, will continue to evolve as we gain increasing insight into our immune response to the virus. Here, we evaluated four high-throughput serologic tests for detection of anti-SARS-CoV-2 IgG antibodies, from Abbott Laboratories (Abbott Park, IL), Epitope Diagnostics, Inc. (San Diego, CA), Euroimmun (Lubeck, Germany), and Ortho-Clinical Diagnostics (Rochester, NY), using a panel of serially collected serum samples (<i>n</i> = 224) from 56 patients with confirmed coronavirus disease 2019 (COVID-19), healthy donor sera from 2018, and a cross-reactivity serum panel collected in early 2020. The sensitivities of the Abbott, Epitope, Euroimmun, and Ortho-Clinical IgG assays in convalescent-phase serum samples collected more than 14 days post-symptom onset or post-initial positive reverse transcriptase PCR (RT-PCR) result were 92.9% (78/84), 88.1% (74/84), 97.6% (82/84), and 98.8% (83/84), respectively. Among unique convalescent patients, sensitivities of the Abbott, Epitope, Euroimmun, and Ortho-Clinical anti-SARS-CoV-2 IgG assays were 97.3% (36/37), 73% (27/37), 94.6% (35/37), and 97.3% (36/37), respectively. Overall assay specificity/positive predictive values based on a 5% prevalence rate were 99.6%/92.8%, 99.6%/90.6%, 98.0%/71.2%, and 99.6%/92.5%, respectively, for the Abbott, Epitope, Euroimmun, and Ortho-Clinical IgG assays. In conclusion, we show high sensitivity in convalescent-phase sera and high specificity for the Abbott, Euroimmun, and Ortho-Clinical anti-SARS-CoV-2 IgG assays. With the unprecedented influx of commercially available serologic tests for detection of antibodies against SARS-CoV-2, it remains imperative that laboratories thoroughly evaluate such assays for accuracy prior to implementation.
Genetic profiles of ten Dirofilaria immitis isolates susceptible or resistant to macrocyclic lactone heartworm preventives (2017)

MiSeq technology provided a suitable methodology to work with the microfilarial samples. The list of SNPs that showed good predictability for ML resistance was narrowed. Additional phenotypically well characterized D. immitis isolates are required to finalize the best set of SNPs to be used for large scale ML resistance screening.
Pseudo Label based Unsupervised Deep Discriminative Hashing for Image Retrieval (2017)

Hashing methods play an important role in large scale image retrieval. Traditional hashing methods use hand-crafted features to learn hash functions, which can not capture the high level semantic information. Deep hashing algorithms use deep neural networks to learn feature representation and hash functions simultaneously. Most of these algorithms exploit supervised information to train the deep network. However, supervised information is expensive to obtain. In this paper, we propose a pseudo label based unsupervised deep discriminative hashing algorithm. First, we cluster images via K-means and the cluster labels are treated as pseudo labels. Then we train a deep hashing network with pseudo labels by minimizing the classification loss and quantization loss. Experiments on two datasets demonstrate that our unsupervised deep discriminative hashing method outperforms the state-of-art unsupervised hashing methods.
Isolation of Auxotrophic Mutants of <i>Methylophilus methylotrophus</i> by Modified-Marker Exchange (1988)

A method for stabilizing a transposon (Tn5) has been developed which allows the isolation of stable auxotrophic mutants of Methylophilus methylotrophus ASI. Insertion of Tn5 into a cloned M. methylotrophus ASI DNA fragment encoding anthranilate synthase followed by transfer of the vector with the modified trpE gene to M. methylotrophus ASI resulted in unstable auxotrophs among the recombinants. Deletion of IS50R, which encodes transposase production from Tn5, stabilized the transposon after mobilization to M. methylotrophus ASI. When trpE genes with the modified Tn5 inserts were mobilized into M. methylotrophus ASI, stable, kanamycin-resistant tryptophan auxotrophs were obtained by double-crossover homologous recombination with the chromosome.
Role of temporalis muscle over activity in chronic tension type headache: effect of yoga based management. (2008)

The role of central versus peripheral mechanisms has always been questioned while explaining the etiopathogenesis of chronic tension type headache (CTTH). The following study was done to study the role of muscle spasm in CTTH. 15 patients of CTTH and 7 age matched controls were included in the study and their m. temporalis EMG was recorded for one minute each during rest, mental activity and maximal voluntary contraction and subjective pain scoring was done by visual analogue scale. The results revealed significant overactivity of m.temporalis in CTTH patients at rest when compared with control subjects (P = 0.01 and 0.03 left and right side respectively). After respective interventions namely non steroidal anti inflammatory drugs, botulinum toxin injections and yogic life style course, the EMG records revealed decrease in the mean EMG amplitude of m. temporalis during rest and mental activity more significantly after yoga based interventions (P = 0.03) and subjective pain scores decreased from 7.00 +/- 2.10 to 2.00 +/- 1.26 (P = 0.02) supporting the beneficial effect of such non invasive techniques.
Fundamental limitaions of a small VLF antenna for submarines (1958)

A submarine requires a small VLF antenna for reception while submerged. Since the propagation in sea water is nearly vertical (downward from the surface), the only operative types are horizontal dipoles, electric and magnetic. The electric dipole is coupled by conduction and the magnetic dipole by induction in a loop. The former has no resonance and nearly unlimited bandwidth, but fails when not submerged. The latter, by resonance, is able to present much greater interception area and available power. The magnetic interception area is determined by the size of the radome and by the radianlength or skin depth in sea water (2 meters at 15 kc). The radiation power factor, which is essential to bandwidth and efficiency, is influenced also by the size of the inductor and by the magnetic permeability of an iron core. Simple formulas illustrate these relations for the idealized spherical shape of radome, coil and core. Omnidirectivity in azimuth requires crossed coils in a two-phase circuit.
Genetics of Swarming Motility in<i>Salmonella enterica</i>Serovar Typhimurium: Critical Role for Lipopolysaccharide (2000)

Salmonella enterica serovar Typhimurium can differentiate into hyperflagellated swarmer cells on agar of an appropriate consistency (0.5 to 0.8%), allowing efficient colonization of the growth surface. Flagella are essential for this form of motility. In order to identify genes involved in swarming, we carried out extensive transposon mutagenesis of serovar Typhimurium, screening for those that had functional flagella yet were unable to swarm. A majority of these mutants were defective in lipopolysaccharide (LPS) synthesis, a large number were defective in chemotaxis, and some had defects in putative two-component signaling components. While the latter two classes were defective in swarmer cell differentiation, representative LPS mutants were not and could be rescued for swarming by external addition of a biosurfactant. A mutation in waaG (LPS core modification) secreted copious amounts of slime and showed a precocious swarming phenotype. We suggest that the O antigen improves surface "wettability" required for swarm colony expansion, that the LPS core could play a role in slime generation, and that multiple two-component systems cooperate to promote swarmer cell differentiation. The failure to identify specific swarming signals such as amino acids, pH changes, oxygen, iron starvation, increased viscosity, flagellar rotation, or autoinducers leads us to consider a model in which the external slime is itself both the signal and the milieu for swarming motility. The model explains the cell density dependence of the swarming phenomenon.
Models of Neurons in the Superior Colliculus and Unsupervised Learning of Parmeters From Time Series (1998)

This research creates four models of neurons in the superior colliculus. The models use various algorithms to create the nonlinear enhancement observed in the neurons of the superior colliculus. Two models use network properties, while two neurons have the enhancement properties explicitly encoded. The models can be divided by form as well. Two models are sigma?pi or perceptron type models and two use a compartmental model based on gamma nodes for dendrites. In addition, this research presents a biologically feasible unsupervised learning algorithm for learning parameter values from transiently presented stimuli. The algorithm is used to learn temporal relationships between stimuli and stimuli amplitudes.

Effect of Silicon Oxidation on Long-Term Cell Selectivity of Cell-Patterned Au/SiO<sub>2</sub>Platforms (2006)

Cellular patterning on silicon platforms is the basis for development of integrated cell-based biosensing devices, for which long-term cell selectivity and biostability remain a major challenge. We report the development of a silicon-based platform in a metal-insulator format capable of producing uniform and biostable cell patterns with long-term cell selectivity. Substrates patterned with arrays of gold electrodes were surface-engineered such that the electrodes were activated with fibronectin to mediate cell attachment and the silicon oxide background was passivated with PEG to resist protein adsorption and cell adhesion. Three types of oxide surfaces, i.e., native oxide, dry thermally grown oxide, and wet thermally grown oxide, were produced to illustrate the effect of oxide state of the surface on long-term cell selectivity. Results indicated that the cell selectivity over time differed dramatically among three patterned platforms and the best cell selectivity was found on the dry oxide surface for up to 10 days. Surface analysis results suggested that this enhancement in cell selectivity may be related to the presence of additional, more active oxide states on the dry oxide surface supporting the stability of PEG films and effectively suppressing the cell adhesion. This research offers a new strategy for development of stable and uniform cell-patterned surfaces, which is versatile for immobilization of silane-based chemicals for preparation of biostable interfaces.

Proximity sensing in robot manipulator motion planning: system and implementation issues (1989)

Results of one effort to implement a motion planning system for a robot arm operating in an uncertain environment are discussed. It is known that path planning algorithms with proven convergence can be designed for some planar and three-dimensional robot arm manipulators operating among unknown obstacles of arbitrary shapes. The attractiveness of such systems lies in their ability to operate in a complex, perhaps even time-varying, unstructured environment. Implementation of these algorithms, however, presents a variety of hardware and algorithmic problems related to: covering the arm with arrays of sensors to form a sensitive skin; processing real-time sensor data; designing complementary algorithms for step-by-step motion planning based on limited local information; and integrating these components, together with global planning algorithms, in a single system. The authors discuss various tradeoffs and solutions implemented in the sensor-based planning system for a planar arm manipulator developed in their laboratory and present a summary of their experiments with it.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
