Lot-Sizing and Lead-time Performance in a Manufacturing Cell (1985)

Many complex multi-item manufacturing shops have high levels of work-in-process because of queueing delays at machines and consequently long manufacturing lead times. These delays are directly related to lot sizes. Two alternative approaches applied to modeling a manufacturing cell—simulation and a novel analytical lot-sizing model (Q-LOTS)—provide very similar results and validate the analytical model.
Doubly-selective Channel Estimation for OFDM Systems Using a Pilot-embedded Training Scheme (2006)

Channel estimation and data detection for OFDM systems over time- and frequency-selective channels are investigated. Relying on the complex exponential basis expansion channel model, a pilot-embedded channel estimation scheme with low computational complexity and spectral efficiency is proposed. A periodic pilot sequence is superimposed at a low power on information bearing sequence at the transmitter before modulation and transmission. The channel state information(CSI) can be estimated using the first-order statistics of the received data. In order to enhance the performance of channel estimation, we recover the transmitted data which can be exploited to estimate CSI iteratively. Simulation results show that the proposed method is suitable for doubly-selective channel estimation for the OFDM systems and the performance of the proposed method can be better than that of the Wiener filter method under some conditions. Through simulations, we also analyze the factors which can affect the system performances.
Unified active filter biquad structures (2004)

The authors present a new biquad filter model based on nullators, norators, current mirrors and passive R (resistor) and C (capacitor) elements. Two implementations derived from the new biquad filter model by using second generation current-controlled conveyors (CCCIIs) and operational transconductance amplifiers (OTAs) are also proposed. The two biquad implementations are capable of achieving five important filter performance parameters simultaneously and without trade-offs, including universal filtering, minimum components count and independent control of ωo and ωo/Q. This is unlike recently reported filter structures which make certain trade-offs that emphasise some parameters at the cost of others. Simulation results are included confirming the theoretical prediction.
Controller Reduction: Concepts and Approaches (1987)

This paper considers the problem of passing from a linear time-invariant high order controller designed for a linear time-invariant plant (of presumably high order) to a low order approximation of the controller. The approximation problem is often best posed as a frequency weighted L ? approximation problem. Many different controller representations are possible, giving different performance of the various reduction algorithms.
Palladium−Phosphinous Acid-Catalyzed NaOH-Promoted Cross-Coupling Reactions of Arylsiloxanes with Aryl Chlorides and Bromides in Water (2004)

A palladium-phosphinous acid-catalyzed and NaOH-promoted coupling method using arylsiloxanes and aryl halides in water has been developed. The POPd1-catalyzed reaction between aryl chlorides or bromides and arylsiloxanes is compatible with various functional groups and affords biaryls in up to 99% yield. This cross-coupling reaction does not require additives such as surfactants or organic cosolvents and proceeds under air, which greatly facilitates operation and catalyst handling.
A Feedback Controlled Stimulator That Delivers Controlled Displacements or Forces to Cutaneous Mechanoreceptors (1975)

Based on a design by the root locus method and utilizing both displacement and force feedback an instrument is described which can be used to deliver either controlled displacement or controlled force stimuli to the skin. Examples of the stimulator operated in each of its two modes are given.
CAD/CAPP Integration through Object Oriented Feature-based Design (1993)

The simplest way to achieve CAD/CAM integration is to generate CNC programs after the completion of the CAD process, while the more rigorous approach in today's integrated manufacturing environment is to prepare the manufacturing process and production plan within the linked design and manufacturing systems. This paper describes the development of an object-oriented feature-based design system for integrating CAD and CAPP. The object-oriented feature-based design system provides an intelligent interface between a CSG based geometric modeller and the process planning functions. The geometric modeller used in this project is the AME (Advanced Modelling Extension) of the commonly used AUTOCAD (Release 11 or above). The concept of feature-object is proposed to express the semantics of integration. Input to the feature-based design system is the Object-Attribute-Value (O-A-V) triplets coding of a workpiece. Based on the AME geometric modeller which is in fact a CSG based solid modeller, the validity of the input geometric features will be ensured. According to the knowledge provided in the rule-based feature mapping system, the design information will be transformed into the appropriate process plan and manufacturing instructions.
Haemodiafiltration, haemofiltration and haemodialysis for end-stage kidney disease (2006)

We were unable to demonstrate whether convective modalities (either HF, HDF or AFB) have significant advantages over HD with regard to clinically important outcomes of mortality, dialysis-related hypotension and hospitalisation. More adequately-powered good quality RCTs assessing clinically important outcomes (mortality, hospitalisation, quality of life) are needed.

Engineers have reported that by patterning the surface of two plastics, they are able to generate a great deal of power with piezoelectric devices.
Luteolin Ameliorates Experimental Lung Fibrosis Both <i>in Vivo</i> and <i>in Vitro</i>: Implications for Therapy of Lung Fibrosis (2010)

Lonicera japonica (Caprifoliaceae) has been known as an anti-inflammatory herb in traditional Chinese medicine for thousands of years and is used constantly for upper respiratory tract infections. Luteolin, an active flavonoid compound isolated from Lonicera japonica, has a spectrum of biological activities, especially with antioxidative and anti-inflammatory properties. However, whether luteolin has a direct inhibitory effect on lung fibrosis has not been established. In this study, we examined the effects of luteolin on lung fibrosis both in vivo and in vitro. We found that oral administration of luteolin (10 mg/kg) efficiently suppressed the neutrophil infiltration as well as TNF-α and IL-6 elevation in the bronchoalveolar lavage fluid in bleomycin-instilled C57BL/6J mice. Luteolin also alleviated collagen deposition, TGF-β1 expression, and lung fibrosis upon bleomycin instillation. A similar tendency was observed in both early and delayed luteolin-treated groups. Next, our in vitro studies showed that luteolin inhibited TGF-β1-induced α-SMA, type I collagen, and vimentin expression in primary cultured mouse lung fibroblasts. Moreover, luteolin significantly blocked TGF-β1-mediated epithelial marker (E-cadherin) downregulation and mesenchymal cell markers (fibronectin and vimentin) upregulation, as well as retaining epithelial morphology in human alveolar epithelial-derived A549 cells. Additionally, luteolin could attenuate TGF-β1-induced Smad3 phosphorylation in both lung fibroblasts and A549 cells. These findings suggest that luteolin has a potent antifibrotic activity; this effect was mediated, at least in part, by inhibition of lung inflammation and suppression of myofibroblast differentiation as well as epithelial-to-mesenchymal transition.
Endemicity of cholera in Surabaya, Indonesia. (1979)

As the seventh pandemic of cholera is caused by V. cholerae biotype El Tor, the former criteria for endemicity of cholera need to be reconsidered as regards their applicability in areas that are infected with cholera. As the mortality rate of cholera nowadays can be reduced to a very low level due to modern methods of treatment, it is suggested that the infection rates of cholera should be taken into consideration as criteria of cholera endemicity, i.e. 1. Five years persistence of cholera cases in a given area. 2. Five percent infection rate among family contacts of cholera cases. 3. Minimum infection rate of 1% in a vicinity where cholera cases occur. It was also found that in such an endemic area it is very difficult to eliminate V. cholerae infection from a locality, even when all family contacts are treated with the full dose of tetracycline.

Roughening instability and evolution of the Ge(001) surface during ion sputtering (1994)

We have investigated the temperature-dependent roughening kinetics of Ge surfaces during low energy ion sputtering using energy dispersive x-ray reflectivity. At 150 \ifmmode^\circ\else\textdegree\fi{}C and below, the surface is amorphized by ion impact and roughens to a steady state small value. At 250 \ifmmode^\circ\else\textdegree\fi{}C the surface remains crystalline, roughens exponentially with time, and develops a pronounced ripple topography. At higher temperature this exponential roughening is slower, with an initial sublinear time dependence. A model that contains a balance between smoothing by surface diffusion and viscous flow and roughening by atom removal explains the kinetics. Ripple formation is a result of a curvature-dependent sputter yield.

Managing replicated copies in very large distributed systems (2002)

Data management in very large distributed systems (VLDS) is considered. A replication strategy that can offer a tradeoff between cost and quality of service is discussed. Imperfect replicated data, called quasi-copies, are considered in conjunction with the notion of file stashing. Stashing a file means placing copies of that file in several nodes of a computer network to augment the availability of the file, i.e. to be able to access the file when the file server that holds it is no longer reachable. The stash propagation problem of how to efficiently propagate updates to the stashed copies throughout the system is studied.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Orthogonal wide azimuth surveys: acquisition and imaging (2012)

Wide azimuth seismic surveying is firmly established as a key element in subsalt exploration and production in the Gulf of Mexico. The challenge now facing the industry is to further improve subsalt images in areas with existing wide azimuth coverage. Orthogonal wide azimuth acquisition, acquiring a second wide azimuth dataset over existing wide azimuth data, is a technique that provides close to full azimuth coverage while utilizing existing wide azimuth data. A case study performed in the Gulf of Mexico demonstrates that the increased source and receiver illumination created by orthogonal wide azimuth surveys significantly improves imaging results and increases the effectiveness of the tomography and salt interpretation steps.

An Hypothesis concerning the Three Days of Darkness among the Nephites (1993)

Abstract Aspects of the three days of darkness following the three-hour period of intense destruction described principally in 3 Nephi are discussed, including: (1) the strange absence of rain among the destructive mechanisms described; (2) the source of the intense lightning, which seems to be unaccompanied by rain; (3) a mechanism to account for the inundation of the cities of Onihah, Mocum, and Jerusalem, which were not among the cities which "sunk in the depths of the sea"; and (4) the absence in the histories of contemporary European and Asiatic civilizations of corresponding events, which are repeatedly characterized in 3 Nephi as affecting "the face of the whole earth."
A molecular dynamics study of the 41‐56 β‐hairpin from B1 domain of protein G (1999)

The structural and dynamical behavior of the 41-56 beta-hairpin from the protein G B1 domain (GB1) has been studied at different temperatures using molecular dynamics (MD) simulations in an aqueous environment. The purpose of these simulations is to establish the stability of this hairpin in view of its possible role as a nucleation site for protein folding. The conformation of the peptide in the crystallographic structure of the protein GB1 (native conformation) was lost in all simulations. The new equilibrium conformations are stable for several nanoseconds at 300K (>10 ns), 350 K (>6.5 ns), and even at 450 K (up to 2.5 ns). The new structures have very similar hairpin-like conformations with properties in agreement with available experimental nuclear Overhauser effect (NOE) data. The stability of the structure in the hydrophobic core region during the simulations is consistent with the experimental data and provides further evidence for the role played by hydrophobic interactions in hairpin structures. Essential dynamics analysis shows that the dynamics of the peptide at different temperatures spans basically the same essential subspace. The main equilibrium motions in this subspace involve large fluctuations of the residues in the turn and ends regions. Of the six interchain hydrogen bonds, the inner four remain stable during the simulations. The space spanned by the first two eigenvectors, as sampled at 450 K, includes almost all of the 47 different hairpin structures found in the database. Finally, analysis of the hydration of the 300 K average conformations shows that the hydration sites observed in the native conformation are still well hydrated in the equilibrium MD ensemble.
A 3–5 GHz Current-Reuse $g_{m}$-Boosted CG LNA for Ultrawideband in 130 nm CMOS (2011)

This paper presents a low-power CMOS transconductance “ <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gm</i> ” boosted common gate (CG) ultrawideband (UWB) low noise amplifier (LNA) architecture, operating in the 3-5 GHz range, employing current-reuse technique. This proposed UWB CG LNA utilizes a common source (CS) amplifier as the <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gm</i> -boosting stage which shares the bias current with the CG amplifying stage. A detailed mathematical analysis of the LNA is carried out and the different design tradeoffs are analyzed. The LNA circuit was designed and fabricated using the 130-nm IBM CMOS process and it achieved input return loss (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> ) and output return loss (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">22</sub> ) variations of respectively - 8.4 to - 40 dB and - 14 to - 15 dB within the pass-band. The LNA exhibits almost flat forward power gain (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">21</sub> ) of 13 dB and a reverse isolation (S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">12</sub> ) variation of -55 dB to -40 dB, along with a noise figure (NF) ranging between 3.5 and 4.5 dB. The complete circuit (with output buffer) draws only 3.4 mW from a 1 V supply voltage.
ASBMT Consensus Grading for Cytokine Release Syndrome and Neurologic Toxicity Associated with Immune Effector Cells (2018)

Chimeric antigen receptor (CAR) T cell therapy is rapidly emerging as one of the most promising therapies for hematologic malignancies. Two CAR T products were recently approved in the United States and Europe for the treatment of patients up to age 25 years with relapsed or refractory B cell acute lymphoblastic leukemia years "?>and/or adults with large B cell lymphoma. Many more CAR T products, as well as other immunotherapies, including various immune cell- and bi-specific antibody-based approaches that function by activation of immune effector cells, are in clinical development for both hematologic and solid tumor malignancies. These therapies are associated with unique toxicities of cytokine release syndrome (CRS) and neurologic toxicity. The assessment and grading of these toxicities vary considerably across clinical trials and across institutions, making it difficult to compare the safety of different products and hindering the ability to develop optimal strategies for management of these toxicities. Moreover, some aspects of these grading systems can be challenging to implement across centers. Therefore, in an effort to harmonize the definitions and grading systems for CRS and neurotoxicity, experts from all aspects of the field met on June 20 and 21, 2018, at a meeting supported by the American Society for Blood and Marrow Transplantation (ASBMT) in Arlington, VA. Here we report the consensus recommendations of that group and propose new definitions and grading for CRS and neurotoxicity that are objective, easy to apply, and ultimately more accurately categorize the severity of these toxicities. The goal is to provide a uniform consensus grading system for CRS and neurotoxicity associated with immune effector cell therapies, for use across clinical trials and in the postapproval clinical setting.
Separating and reattaching microbial fuel cells on sediment bottom (2013)

Experimental data is presented demonstrating how microbial fuel cells (MFC's) could survive temporary (60 min) sediment separation and reattachment without any adverse effects from oxygen exposure. Mud-enclosed anodes, housed in open bottom chambers, were detached or “unplugged” from the sediment with no change in their open circuit voltage levels. For reattaching MFC devices on the sediment, oxygen content that could be inadvertently trapped or ingested by the MFC platform was shown to be consumed within 1 day using a 1% mud/seawater solution.
Customers, Strategy and Performance (1993)

A true marketing orientation is associated with superior performance in the UK retail financial services industry. This finding runs counter to some recent criticism of marketing influence on the banking sector. Empirical research in the UK retail financial service industry found that successful companies appear to balance a profit orientation with an orientation towards the most difficult market to satisfy, the wealthy. Successful companies focused on a distinct group of customers, and did not rely on traditional methods such as existing family links to attract business. They also maintained tighter control over profitability and costs. Utilizes expert assessment as the basis of performance measurement, and compares this technique with an alternative, peer assessment. Uses the Delphi technique to develop a performance measure, and both performance ratings and findings suggest that the performance of expert assessment and peer assessment as performance measurement methods is similar.

Feedback controlled nano-positioner using fiber optic EFPI sensor with novel demodulation technique (2005)

For the translation stage of nanometer scale, fiber optic EFPI sensor is suggested for the feedback control system on account of its high sensitivity, small size, simple system and relatively low cost. The novel signal processing algorithm for the real-time demodulation of EFPI output signal was developed and verified. The local linearity in the adjacent fringe values was shown, and used for the sinusoidal approximation of the nonlinear output signal. The real-time signal processing program was designed and the intensity signal of the EFPI sensor was demodulated to the phase shift with this program. The theoretical resolution of 0.36~8.6 <i>nm</i> in the displacement range of 0~200 <i>μm</i> was obtained. The sensor system was applied to the 1-D nano-positioner with a Piezo-electric actuator. The positioner successfully reached to the desired destination within 1 <i>nm</i> accuracy.
