Effects on MRI due to altered rf polarization near conductive implants or instruments (2005)

In magnetic resonance imaging near metal parts variations in radio frequency (rf)-amplitude and of receive sensitivity must be considered. For loop structures, e.g., vascular stents, B1 produces rf eddy currents in accordance to Faraday's law; the B1-related electrical rf field E1 injects directly to elongated structures (e.g., wires). Locally, the rf magnetic field Bl,ind (induced B1) is superimposed onto the rf field from the transmitter coil, which near the metal can dominate spin excitation. Geometry and arrangement of the parts determine the polarization of B(1,ind). Components parallel to B0 are of special interest. A copper sheet (100 mm x 15 mm, 3 mm thick) and a 27 cm long copper wire were examined in a water phantom using the spin-echo (SE) technique. In addition to rf-amplitude amplification, rf-phase shift due to z components of B(1,ind) could be detected near the metallic objects. Periodic rf-amplitude instabilities had an amplified effect for phase-shifted regions. Phase-encoding artifacts occurred as distinct ghosts (TR=200 ms) or band-like smearing (TR=201 ms) from affected spin ensembles. SE phase imaging can potentially be used in interventional magnetic resonance imaging for background-free localization of metallic markers.
Infectivity of an Asymptomatic Patient With Middle East Respiratory Syndrome Coronavirus Infection (2017)

During the MERS outbreak in Korea, one case of asymptomatic or mild MERS-CoV infection was noted. Eighty-two persons were exposed to the case without protection. They were isolated and RT-PCR and serology for MERS were performed. There was no transmission through an asymptomatic MERS case in this study.
Human Monoclonal Antibodies Produced by Epstein-Barr Virus Immortalized Cell Lines: Technical and Theoretical Principles (1988)

Continuous cell lines that produce monoclonal antibodies are now routinely established from mouse and rat origin according to the hybridoma method (Köhler and Milstein, 1975). This method is still, to a large extent, limited to rodents and only very few positive results using human cells have been reported. The hybridoma technology has introduced to research and medicine a new type of reagent that differs both qualitatively and quantitatively from the conventional polyclonal antibodies. An important aspect of monoclonal antibodies is the species from which they are derived. Monoclonal antibodies are generated from manipulated lymphocytes and obviously reflect the humoral immune response of the donor. The antibody response of the human immune system differs in scope and fine specificity from that of the rodent. For example, xenogeneic antibodies usually react with non-polymorphic determinants, whereas allo-antibodies would, by definition, recognize polymorphic determinants of human cells and might have the fine specificity necessary to define tumour-associated antigens. In general, mouse monoclonal antibodies to human cell surface antigens can distinguish between normal and transformed cells only to a limited extent. In addition, there is an obvious advantage in therapy when an allogeneic antibody is used compared with a xenogeneic one; the latter usually elicits a strong response in the host against the foreign antibody, with dominance of anti-idiotype antibodies (Shawler et al., 1985)
The Implications of Past-Tense Syntax in the Book of Mormon (2015)

In the middle of the 16th century there was a short-lived surge in the use of the auxiliary did to express the affirmative past tense in English, as in Moroni «did arrive» with his army to the land of Bountiful (Alma 52:18). The 1829 Book of Mormon contains nearly 2,000 instances of this particular syntax, using it 27% of the time in past-tense contexts. The 1611 King James Bible — which borrowed heavily from Tyndale’s biblical translations of the 1520s and ’30s — employs this syntax less than 2% of the time. While the Book of Mormon’s rate is significantly higher than the Bible’s, it is close to what is found in other English-language texts written mainly in the mid- to late 1500s. And the usage died out in the 1700s. So the Book of Mormon is unique for its time — this is especially apparent when features of adjacency, inversion, and intervening adverbial use are considered. Textual evidence and syntactic analysis argue strongly against both 19th-century composition and an imitative effort based on King James English. Book of Mormon past-tense syntax could have been achieved only by following the use of largely inaccessible 16th-century writings. But mimicry of lost syntax is difficult if not impossible, and so later writers who consciously sought to imitate biblical style failed to match its did-usage at a deep, systematic level. This includes Ethan Smith who in 1823 wrote View of the Hebrews, a text very different from both the Bible and the Book of Mormon in this respect. The same may be said about Hunt’s The Late War and Snowden’s The American Revolution.

Resource‐Constrained Project Scheduling for Timely Project Completion with Stochastic Activity Durations (2009)

We investigate resource‐constrained project scheduling with stochastic activity durations. Various objective functions related to timely project completion are examined, as well as the correlation between these objectives. We develop a GRASP‐heuristic to produce high‐quality solutions, using so‐called descriptive sampling. The algorithm outperforms existing algorithms for expected‐makespan minimization. The distribution of the possible makespan realizations for a given scheduling policy is also studied.
Atrial flutter can be terminated by a class III antiarrhythmic drug but not by a class IC drug (1994)

In atrial flutter, chemical conversion with class I drugs is often unsuccessful, whereas class III drugs seem more promising. The different electrophysiological effects of these drugs may explain this discrepancy. To date, only experimental data show the differential effects of these drugs on conversion rate and atrial flutter cycle length. This study evaluates the effects of the class IC antiarrhythmic drug flecainide, and of dofetilide, a new class III drug, on conversion rate and flutter cycle length in patients with atrial flutter. Flecainide (11 patients) was given as an intravenous bolus of 2 mg.kg-1 in 10 min and dofetilide (10 patients) as a maximum intravenous bolus of 8 micrograms.kg-1 in 15 min. Baseline characteristics were comparable between both groups. Only one patient treated with flecainide converted to sinus rhythm. This patient showed the largest flutter cycle length increase (280 to 420 ms). By contrast, seven of the 10 patients treated with dofetilide converted to sinus rhythm. Patients treated with flecainide showed a significantly larger increase in atrial flutter cycle length at the end of the infusion compared to the dofetilide-treated patients (from 226 +/- 28 to 317 +/- 52 ms vs from 221 +/- 26 to 239 +/- 39 ms, respectively). In conclusion, dofetilide is more effective than flecainide in the conversion of atrial flutter to sinus rhythm, despite the fact that flecainide produced a more prolonged flutter cycle length. Thus, action potential prolongation in the absence of conduction slowing seems more effective in terminating human atrial flutter than depression of the excitability.
Enhanced performance of tin halide perovskite solar cell by addition of lead thiocyanate (2018)

Organic-inorganic hybrid halide perovskites have attracted great attention as a new type of photovoltaic materials. However, lead (Pb) perovskite solar cells (PSCs) would cause environmental pollution in future large-scale applications. Therefore, it is imperative to find environmentally-friendly metals to replace lead. Although tin (Sn) halide perovskites can be regarded as a valid alternative to lead perovskites, their poor stability and lower conversion efficiency hinder the substitution of Sn for Pb. In this work, highly uniform and pinhole-free perovskite films were prepared by the introduction of a small amount of lead thiocyanate in precursor solutions. The CH<sub>3</sub>NH<sub>3</sub>SnI<sub>3</sub> (MASnI<sub>3</sub>) films with Pb additive show an absorption edge of 950 nm. Besides, lead ions can depress the LUMO energy level of Sn-based perovskite materials, which is a benefit to an increase in the opencircuit voltages of PSCs. Consequently, the enhanced performance was achieved in the PSCs based on MASnI<sub>3</sub> with a fill factor of 66%, open circuit voltage of 0.54 V and maximum power conversion efficiency of 6.03%.
Strength Degradation by Projectile Impacts (1973)

The impacting of ceramic components by small projectiles can lead to strength degradation caused by the formation of Hertzian cracks. The conditions which produce degradation are analyzed in terms of the momentum and elastic properties of the projectile. A critical momentum must be exceeded before strength loss can occur, and the critical condition depends on the surface condition of the ceramic. Comparison of the analytical predictions with data for SiC confirms the reliability of the analysis.
Bispecific Enzyme-Linked Signal-Enhanced Immunoassay with Subattomole Sensitivity (2005)

A bispecific enzyme-linked signal-enhanced immunoassay (BiELSIA) was developed with markedly increased sensitivity. Antimyosin, the detection antibody, was linked to the signal probespecific antibody. Probes consisted of diethylenetriamine pentaacetic acids attached to polylysine modified with up to seven or eight horseradish peroxidase (HRP) units. Each bispecific antibody bound two polymer probes, providing twice the signal. Using BiELSIA in a competitive inhibition immunoassay format with an average of 1.5, 3, 4.5, 6, and 7.5 HRP units per polymer-probe, the sensitivity of standard enzyme-linked immunosorbent assay (10(13) mole) was increased to 10(15), 10(18), 10(19), 10(20), and 10(-21) mol (< or = 1,000 molecules), respectively. BiELSIA detected cardiac myosin heavy chain fragments in sera of patients obtained at the time of emergency department admission for acute myocardial infarction, but not in normal sera. This technology should be applicable for detection of cancer, human immunodeficiency virus, prion, and other antigens that are present in concentrations too low for detection by current immunoassays.
Braiding of hybrid composite propeller blades (1991)

Over the past decade carbon and glass fibre epoxide resin hybrid composites have proven to be ideal materials for the construction of efficient lightweight propeller blades for commuter aircraft. Designing blades with correct stiffness characteristics requires careful use of the glass and carbon fibre combinations. Braiding is an excellent way of combining these fibres and producing the required hybrid construction
Desiccant properties and their effect on cooling system performance (1989)

Relationships between the desiccant matrix heat capacity, the heat and mass transfer resistance, and the isotherm shape will also influence desiccant cooling system performance. These relationships are quantified by computer simulation
Effect of film deposition rate on the thermoelectric output of tungsten-rhenium thin film thermocouples by DC magnetron sputtering (2020)

Abstract In micro–nano manufacturing, the deposition rate is one of the most basic parameters for the preparation of the film. In this paper, we use the tungsten–rhenium (W-5Re and W-26Re) alloy thin films as the research object and choose direct current (DC) magnetron sputtering to fabricate films on the alumina substrate. With the help of three factors and three levels of an orthogonal table, nine orthogonal experiments are designed to study the influences of argon flow rate, sputtering power and vacuum degree on the deposition rate. Thickness and composition are measured by scanning electron microscopy and x-ray diffraction respectively. In order to maintain the integrity of the film, the deposition thickness of the film is controlled by simulation so that the thermal stress is within the required range. In addition, the thermoelectric output is improved by comparing tungsten-rhenium thin film thermocouples (TFTCs) with different deposition rates. Experimental results show that sputtering power has a greater effect than other factors. The deposition rate of the W-5Re and W-26Re film can reach 24.911 nm min −1 and 25.756 nm min −1 at 600 W. The output of the TFTCs prepared at 600 W is about 10% higher than that at 200 W. TFTCs made with the fastest deposition rate parameters have excellent characteristics which could continuously work at 1273 K and the maximum EMF is 39.7 mV and the average Seebeck coefficient at 1273 K is 31.2 μ V K −1 .
Vegetative and Reproductive Characteristics of Poinsettia Altered by a Graft-transmissible Agent (1991)

Poinsettia (Euphorbia pulcherrima Wind. ex. Klotzsch) cultivars were divided into free-branching and restricted-branching groups. Auto and reciprocal grafts were made among three free-branching cultivars, Annette Hegg Brilliant Diamond (BD), Annette Hegg Topwhite (TW), and Annette Hegg Hot Pink (HP), and two restricted-branching cultivars, Eckespoint C-1 Red (CR) and Eckespoint C-1 White (CW). when CR scions were grafted onto BD stocks, vegetative characteristics of branching pattern and leaf morphology of CR plants were altered when compared to the control graft combination CR/CR (scion/stock). Branching pattern was determined by pinching the scion above the 12th node and measuring axillary shoot length, diameter, and node number 30 days later. CR scions grafted onto BD stocks produced a plant very similar to BD plants when axillary shoot length and node number were compared. However, axillary shoot diameter and leaf morphology were intermediate between CR and BD plants. Changes were retained after two generations of serial vegetative propagation and are considered permanent. The reproductive characteristics of anthesis date, bract color, and cyathia cluster diameter were not influenced by the stock. CR/BD plants produced twice as many axillary inflorescences as BD/BD or BD/CR plants, while CR/CR plants did not produce any. All of the free-branching cultivars were able to alter the vegetative characteristics of all of the restricted-branching cultivars.
Direct versus Facility Centric Load Control for Automated Demand Response (2010)

Direct load control (DLC) refers to the scenario where third party entities outside the home or facility are responsible for deciding how and when specific customer loads will be controlled in response to Demand Response (DR) events on the electric grid. Examples of third parties responsible for performing DLC may be Utilities, Independent System Operators (ISO), Aggregators, or third party control companies. DLC can be contrasted with facility centric load control (FCLC) where the decisions for how loads are controlled are made entirely within the facility or enterprise control systems. In FCLC the facility owner has more freedom of choice in how to respond to DR events on the grid. Both approaches are in use today in automation of DR and both will continue to be used in future market segments including industrial, commercial and residential facilities. This paper will present a framework which can be used to differentiate between DLC and FCLC based upon where decisions are made on how specific loads are controlled in response to DR events. This differentiation is then used to compare and contrast the differences between DLC and FCLC to identify the impact each has on:(1)Utility/ISO and third party systems for managing demand response, (2)Facility systems for implementing load control, (3)Communications networks for interacting with the facility and (4)Facility operators and managers. Finally a survey of some of the existing DR related specifications and communications standards is given and their applicability to DLC or FCLC. In general FCLC adds more cost and responsibilities to the facilities whereas DLC represents higher costs and complexity for the Utility/ISO. This difference is primarily due to where the DR Logic is implemented and the consequences that creates. DLC may be more certain than FCLC because it is more predictable - however as more loads have the capability to respond to DR signals, people may prefer to have their own control of end-use loads and FCLC systems. Research is needed to understand the predictability of FCLC which is related to the perceived value of the DR from the facility manager or home owner's perspective.
Image Formation Algorithm for the Implementation of Circular Scanning SAR (2006)

This paper presented circular scanning synthetic aperture radar (SAR) based on circular scanning antenna. The work principle of this scanning radar was described. The variations of synthetic, aperture time, azimuth resolution and time-bandwidth product were analyzed. Also a focused imaging algorithm instead of DBS was used to form high resolution image. This algorithm based on extended chirp scaling (ECS) could compensate phase errors with high precision. The versatile image formation flow was composed of burst imaging, geometric correction and mosaicking. The computer simulation results confirmed that the versatile image formation flow could be used to image precisely for circular scanning SAR

Seamless Roaming in Wireless Networks for Video Streaming (2005)

Roaming across multiple basic service sets (BSS) using access points (AP) in wireless LAN (WLAN) always poses considerable challenges, as it will cause heavy packet loss error. Especially for real-time video streaming, it will damage receiving video quality. In this paper, we combine the benefits of multiple description coding (MDC) and multipath routing to maintain a best constant video quality despite packet loss when roaming in WLAN. We incorporate a channel status detection mechanism to decide which channel will be selected or multiple channels will be used to take advantage of path diversity to deliver the streaming video content. The loss-rate and round-trip time are used to determine the channel status by using active probing. Simulation results indicate that the proposed method can significantly improve the quality of streamed video when a mobile client roams in WLAN.
Determination of subboundary misorientation in aluminum by X-ray diffraction (1970)

A method has been developed for determining the average misorientation of subboundaries in both melt grown and polygonized single crystals of aluminum. Symmetrical tilt subboundaries were the predominant type of substructure found in both types of single crystals. Résumé Les auteurs ont mis au point une technique pour déterminer la désorientation moyenne des sous-joints dans des monocristaux d'aluminium obtenus soit à partir d'un bain liquide soit par polygonisation. Les sous-joints de flexion symétriques sont prédominants pour la sous-structure observées dans les deux types de monocristaux.

Transcription-Factor-Mediated DNA Looping Probed by High-Resolution, Single-Molecule Imaging in Live E. coli Cells (2013)

DNA looping mediated by transcription factors plays critical roles in prokaryotic gene regulation. The "genetic switch" of bacteriophage λ determines whether a prophage stays incorporated in the E. coli chromosome or enters the lytic cycle of phage propagation and cell lysis. Past studies have shown that long-range DNA interactions between the operator sequences O(R) and O(L) (separated by 2.3 kb), mediated by the λ repressor CI (accession number P03034), play key roles in regulating the λ switch. In vitro, it was demonstrated that DNA segments harboring the operator sequences formed loops in the presence of CI, but CI-mediated DNA looping has not been directly visualized in vivo, hindering a deep understanding of the corresponding dynamics in realistic cellular environments. We report a high-resolution, single-molecule imaging method to probe CI-mediated DNA looping in live E. coli cells. We labeled two DNA loci with differently colored fluorescent fusion proteins and tracked their separations in real time with ∼40 nm accuracy, enabling the first direct analysis of transcription-factor-mediated DNA looping in live cells. Combining looping measurements with measurements of CI expression levels in different operator mutants, we show quantitatively that DNA looping activates transcription and enhances repression. Further, we estimated the upper bound of the rate of conformational change from the unlooped to the looped state, and discuss how chromosome compaction may impact looping kinetics. Our results provide insights into transcription-factor-mediated DNA looping in a variety of operator and CI mutant backgrounds in vivo, and our methodology can be applied to a broad range of questions regarding chromosome conformations in prokaryotes and higher organisms.
Pneumococcal bacteremia--no change in mortality in 30 years: analysis of 104 cases and review of the literature. (1987)

We evaluated 104 cases of pneumococcal bacteremia retrospectively: 55 adults and 49 children. The overall mortality rate was 33% in adults, and 6% in children. Mortality was associated with old age, severe underlying disease, vague clinical presentation, multilobar pneumonia, leukopenia and metabolic acidosis. Both vigorous treatment with mechanical ventilation devices, vasopressors and steroids, and sophisticated monitoring in the Intensive Care Unit did not improve survival. In six cases (5.8%) the pneumococcus was resistant to penicillin G. In reviewing the literature of the last 30 years, no change in mortality rate was noted. Vaccination of population at risk is highly recommended.
Principal Components and Factor Analysis: Part I—Principal Components (1980)

Principal components and factor analysis are two techniques which are finding increasing application to quality engineers who are concerned with processes with more than one response variable. In this, the first of a three-part series, the concept of principal components is introduced. Estimations, significance tests, and residual analysis are presented along with two numerical examples. Parts two and three will be found in succeeding issues.
