The impact of alternative performance measures on single-period inventory policy (2006)

While many firms and researchers have developed various supply chain solutions, there are many underlying reasons why these solutions have not been adopted in practice. Some key reasons, as articulated by Lee and Billington (1992), include organizational barriers, coordination challenges among marketing, manufacturing, and logistics, technical challenges in the area of information systems, as well as conflicting supply chain performance metrics. Other key reasons are due to alternative performance measures besides total expected relevant cost, which include sales target, product substitution, product clearance, sales per square foot, etc. In order to understand how these alternative performance measures affect the supply chain solution, we make an initial attempt to analyze how alternative measures would affect the simplest form of inventory policy, namely, the newsvendor solution. To identify various alternative measures and to explore how such order decisions are made, we conducted a simple experiment by giving a single-period inventory problem to 250 MBA students and 6 professional buyers who order fashion items. We observed that both groups select their order quantities less than the newsvendor solution and made their ordering decisions based on various specific performance metrics besides total expected cost. These observations have motivated us to analyze how these performance metrics would affect the ordering decision. Our analysis indicates that, under these performance metrics, it is rational for the decision maker to order less than the newsvendor solution.
A 5-GHz Band WLAN SiGe HBT Power Amplifier IC with Novel Adaptive-Linearizing CMOS Bias Circuit (2015)

This paper presents a novel CMOS bias topology serving as not only a bias circuit but also an adaptive linearizer for SiGe HBT power amplifier (PA) IC. The novel bias circuit can well keep the base-to-emitter voltage (Vbe) of RF amplifying HBT constant and adaptively increase the base current (Ib) with the increase of the input power. Therefore, the gain compression and phase distortion performance of the PA is improved. A three-stage 5-GHz band PA IC with the novel bias circuit for WLAN applications is designed and fabricated in IBM 0.35µm SiGe BiCMOS technology. Under 54Mbps OFDM signal at 5.4GHz, the PA IC exhibits a measured small-signal gain of 29dB, an EVM of 0.9% at 17dBm output power and a DC current consumption of 284mA.
Multithreaded processor architectures (1995)

The authors describe how independent streams of instructions, interwoven on a single processor, fill its otherwise idle cycles and so boost its performance. They detail how such multithreaded architectures take the tack of hiding latency by supporting multiple concurrent streams of execution. When a long-latency operation occurs in one of the threads, another begins execution. In this way, useful work is performed while the time-consuming operation is completed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Incoherent asynchronous optical CDMA using goldcodes (1994)

An approach is described for obtaining a correlation output corresponding to the difference between agreements and disagreements in incoherent optics, through the use of additional precoding and balanced detection. Calculations of the correlation spectra and of the probability of BER reveals that the proposed technique, in tandem with gold codes, can accommodate more users than previously reported systems.

Effect of corrugated substrates on light extraction efficiency and the mechanism of growth in pulsed laser deposited Y2O3:Eu3+ thin-film phosphors (2004)

The luminance level of thin-film Y2O3:Eu3+ phosphors deposited by a pulsed laser deposition techniques are not candidates for field emission display because of their low extraction efficiency. A square lattice nanorod-type two-dimensional SiO2 photonic crystal layer (PCL) was built on a quartz glass substrate in an attempt to improve the efficiency of light extraction. The pitch of the PCL was varied, such that 500, 550, and 600nm pitches were produced while maintaining the depth of the PCL fixed at 200nm. The integrated photoluminescence efficiency of an Y2O2:Eu3+ thin-film phosphor deposited on the PCL was improved by 4.8 times and well matched with the calculated result based on the finite-difference time-domain method. The PCL played a significant role not only in enhancing the extraction efficiency but also aiding in the control of the film growth.
Pressurized 1-MeV Electron Accelerator of the Twin-Tank Design for Electron Microscopy (1969)

A pressurized l-MeV electron accelerator was developed after the principle of the symmetrical cascade generator with fully electronic ac supply and voltage regulating systems. A special feature of the new commercial model is the twin-tank design in which the high voltage generator and the accelerator are separated from each other in individual tanks. The two units are connected by a high-ohmic resistor which is enclosed in a pressurized connecting tube. The ripple voltage is negligible (1 × 10-7) and the overall voltage stability is between 1 × 10-6 and 1 × 10-5 in the voltage range from 100 kV up to 1 MV. The electron accelerator is designed as a production model for the supply of a commercial l-MeV electron microscope.
Acute and Long-term Amiloride Inhalation in Cystic Fibrosis Lung Disease: A Rational Approach to Cystic Fibrosis Therapy (1990)

Cystic fibrosis (CF) is the most common inherited fatal disorder among Caucasians. Bronchial mucus in CF contains more potassium and less sodium, which may be due to increased sodium absorption, resulting in a reduced airway water content. We studied 23 patients with CF after inhalation of normal saline or amiloride (10(-3) M), a sodium transport blocker. Mucociliary clearance (MC) and cough clearance (CC) were determined with a gamma camera that traced the movement of 99mTc-labeled, hardened erythrocytes over a 1-h period after the patients inhaled these particles as an aerosol. Before and after each investigation pulmonary function tests (PFT) and blood pressure (BP) were measured. Sputum thread formation was measured by means of a filancemeter. Six of the patients also completed a 3-wk trial of amiloride inhalation therapy. MC increased significantly (p less than 0.001) after acute amiloride inhalation (bronchial deposition, 0.07 mg amiloride) compared with that in the saline control. CC also increased, but not as much as MC. After 3 wk of amiloride inhalation (2 times a day) clearance values (both MC and CC) were markedly enhanced (p less than 0.01); after a similar period of saline inhalation, clearance values were not different from baseline. Sputum filance values also decreased significantly after amiloride inhalation. There were no adverse effects of the amiloride inhalation compared with saline. We conclude that amiloride inhalation administered as a single dose or as long-term therapy is able to increase MC and CC in CF airways and that the effect of 10(-3) M amiloride inhalation on MC lasts at least 40 min.

An online neural network system for computer access security (1993)

A method for identifying computer users based on the individual typing techniques of the users is presented. The identification system is a pattern classification system based on a simulation of an artificial neural network. The user types a known sequence of characters, and the intercharacter times represent a pattern vector to be classified. This vector is presented to the classification system, and the pattern is assigned to a predefined class, thus identifying the user. The major work is divided into two phases: the investigation phase and the implementation phase. Experimental results are discussed, followed by a description of a real-time implementation of this system, using a personal computer, known as the OnLine User Identification System. In an operational trial, the system correctly identified users 97.8% of the time. This intelligent system can be used, in addition to the traditional user name and password procedures, to improve computer security in a cost-effective manner.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The electroencephalogram in childhood basilar artery migraine (1977)

In two pediatric patients with the clinical picture of basilar artery migraine, transient electroencephalographic disturbances were seen. Both children manifested posterior rhythmic delta activity in close temporal proximity to their attacks. Resolution of these abnormalities was documented by serial electroencephalographic tracings. These electroencephalographic findings are consistent with transient dysfunction in the neural structures supplied by the basilar artery and its branches. Pediatric patients in whom there is a clinical picture of basilar artery migraine and who have a family history of migraine and transient electroencephalographic changes of the type herein described need not undergo invasive neurodiagnostic study.
Patient-Specific Blood Vessel Scaffold for Regenerative Medicine (2007)

In this research, we propose a method to construct an artificial blood vessel scaffold with patient-specific complex 3-dimensional shape and biocompatible porous polymer membrane adapted for cell cultivation, by introducing salt leaching technique into a fabrication technique for patient-specific 3D blood vessel model proposed by authors. In this method, a membranous PVA (polyvinyl alcohol) structure of desired 3-dimensional blood vessel shape was fabricated based on CT data. And the PVA structure was dip coated with polymer solution made by dissolving the Caprolactone (3wt%) and NaCl particle (27wt%) into chloroform (organic solvent), Finally, the NaCl particle and the membranous PVA structure were both eluted from the structure by dissolving these materials under water, and finally a patient-specific blood vessel scaffold with desired 3D vascular shape was constructed. Presented scaffold has the mechanical compliance similar to human blood vessel and provides porous polymer structure appropriate for cell cultivation.

Near-field optics inverse-scattering reconstruction of reflective surfaces (1993)

We show that, at multiple scattering, the scattered field amplitude at a plane close to the surface of a perfectly reflecting grating, and thus the image of the grating, does not at all resemble the grating profile. We demonstrate the performance of an inverse-scattering procedure that applies within the range of validity of the Rayleigh hypothesis and that permits the attainment of superresolution in the reconstructed surface profile. This is the first solution, to our knowledge, for cases in which the near-field optics methods established so far do not work.

A Two-Dimensional Low-Diameter Scalable On-Chip Network for Interconnecting Thousands of Cores (2011)

This paper introduces the Spidergon-Donut (SD) on-chip interconnection network for interconnecting 1,000 cores in future MPSoCs and CMPs. Unlike the Spidergon network, the SD network which extends the Spidergon network into the second dimension, significantly reduces the network diameter, well below the popular 2D Mesh and Torus networks for one extra node degree and roughly 25 percent more links. A detailed construction of the SD network and a method to reshuffle the SD network's nodes for layout onto the 2D plane, and simple one-to-one and broadcast routing algorithms for the SD network are presented. The various configurations of the SD network are analyzed and compared including detailed area and delay studies. To interconnect a thousand cores, the paper concludes that a hybrid version of the SD network with smaller SD instances interconnected by a crossbar is a feasible low-diameter network topology for interconnecting the cores of a thousand core system.
Behavior-based control of multi-robot assembly/palletizing systems (2003)

A decentralized palletizing multi-robot system was developed using fuzzy behavior-based control. The system consists of a conveyor, two robots and a vision system. The system's role is to perform a palletizing task using parts arriving on the conveyor. Two control algorithms were compared: a simple algorithm and a behavior-based algorithm combined with fuzzy logic. Thirty experiments were conducted while changing the control algorithm, parts arrival frequency, and conveyor velocity. Performance measures included number of parts taken. number of pallets, robots utilization and work cell utilization. Experimental results indicated better performance for the simple algorithm. However. the fuzzy behavior-based algorithm equalizes the robots utilization. Equal utilization is a major factor in multi-robots systems, and contributes in decreasing mean time between failure (MTBF). We expect that for a heavier loaded system the fuzzy behavior-based algorithm will yield higher performances.
Modulation of the bovine innate immune response by production of 1α,25-dihydroxyvitamin D3 in bovine monocytes (2010)

In cattle, the kidney has been the only known site for production of 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] from 25-hydroxyvitamin D(3) [25(OH)D(3)] by 1alpha-hydroxylase (1alpha-OHase). Based on human studies, it was hypothesized that bovine monocytes could produce 1,25(OH)(2)D(3) upon activation and 1,25(OH)(2)D(3) would regulate expression of vitamin D-responsive genes in monocytes. First, the effects of 1,25(OH)(2)D(3) on bovine monocytes isolated from peripheral blood were tested. Treatment of nonstimulated monocytes with 1,25(OH)(2)D(3) increased expression of the gene for the vitamin D 24-hydroxylase (24-OHase) enzyme by 51+/-13 fold, but 1,25(OH)(2)D(3) induction of 24-OHase expression was blocked by lipopolysaccharide (LPS) stimulation. In addition, 1,25(OH)(2)D(3) increased the gene expression of inducible nitric oxide synthase and the chemokine RANTES (regulated upon activation, normal T-cell expressed and secreted) in LPS-stimulated monocytes 69+/-13 and 40+/-12 fold, respectively. Next, the ability of bovine monocytes to express 1alpha-OHase and produce 1,25(OH)(2)D(3) was tested. Activation of monocytes with LPS, tripalmitoylated lipopeptide (Pam3CSK4), or peptidoglycan caused 43+/-9, 17+/-3, and 19+/-3 fold increases in 1alpha-OHase gene expression, respectively. Addition of 25(OH)D(3) to LPS-stimulated monocytes enhanced expression of inducible nitric oxide synthase and RANTES and nitric oxide production in a dose-dependent manner, giving evidence that activated monocytes convert 25(OH)D(3) to 1,25(OH)(2)D(3). In conclusion, bovine monocytes produce 1,25(OH)(2)D(3) in response to toll-like receptor signaling, and 1,25(OH)(2)D(3) production in monocytes increased the expression of genes involved in the innate immune system. Vitamin D status of cattle might be important for optimal innate immune function because 1,25(OH)(2)D(3) production in activated monocytes and subsequent upregulation of inducible nitric oxide synthase and RANTES expression was dependent on 25(OH)D(3) availability.
High-performance geometric phase elements in silica glass (2017)

High-precision three-dimensional ultrafast laser direct nanostructuring of silica glass resulting in multi-layered space-variant dielectric metasurfaces embedded in volume is demonstrated. Continuous phase profiles of nearly any optical component are achieved solely by the means of geometric phase. Complex designs of half-wave retarders with 90% transmission at 532 nm and &gt;95% transmission at &gt;1 μm, including polarization gratings with efficiency nearing 90% and computer generated holograms with a phase gradient of ∼0.8π rad/μm, were fabricated. A vortex half-wave retarder generating a single beam optical vortex with a tunable orbital angular momentum of up to ±100ℏ is shown. The high damage threshold of silica elements enables the simultaneous optical manipulation of a large number of micro-objects using high-power laser beams. Thus, the continuous control of torque without altering the intensity distribution was implemented in optical trapping demonstration with a total of 5 W average power, which is otherwise impossible with alternate beam shaping devices. In principle, the direct-write technique can be extended to any transparent material that supports laser assisted nanostructuring and can be effectively exploited for the integration of printed optics into multi-functional optoelectronic systems.
Evolving formative assessment for and with ubiquitous technologies (2014)

Formative assessment is a vital part of the learning process. It guides student learning and prepares them for summative assessment. The feedback that accompanies formative assessment is valuable for students' learning. The combination of formative assessment and feedback facilitate the development of self-efficacy. Technology is not only changing the way students study and learn but also how assessment is conducted and managed. Globalisation and corporatisation of universities has changed the way academics work and has had an effect on teaching, assessment and feedback. This paper looks at how formative assessment in an enabling mathematics course has been developed to take advantage of changing technologies in a changing academic world.
Field techniques for high resolution, Part 2 (1986)

Let me turn now to a topic which I, as an interpreter, am just delighted to see on the program — the interrelation between field work, processing and interpretation, and in particular the constraints imposed on each by the others. Specifically, I would like to address the constraints on the field work imposed by two strongly-felt needs of the interpreter today — the need for better resolution, and the need for improved delineation of the faults.
Modeling of electromigration of the through silicon via interconnects (2010)

A finite element model which includes electromigration, thermomigration, stress migration and concentration diffusion is established to study the mass diffusion phenomenon. Numerical experiment is carried out to obtain the electrical, thermal, stress and atomic concentration fields of the sweat and through silicon via (TSV) structure under high current density load. The effectiveness of the electromigration FEM model is confirmed by the simulation of the sweat structure. The results from the simulation are consistent with the observation of the experiment conducted by Dallleau, D. et al. The current crowding, temperature distribution, von Mises and hydrostatic stress distribution and atomic concentration fields of the TSV structure is obtained from the numerical calculation. The current crowding occurs at the corner of the copper pad. The maximum compressive hydrostatic stress happens in the center of the copper via and the center of copper pads are under tensile hydrostatic stress which has important role in the migration of copper atoms. The probable location where the void and hillock may be generated is identified through the atomic distribution after 10000-second electromigration simulation. The migration failure mechanism which is critical for design and application of TSV technology in the 3D package is investigated.
A self-protected architecture for wavelength-division-multiplexed passive optical networks (2003)

We propose a novel network architecture for wavelength-division-multiplexed passive optical networks which can provide bidirectional 1:1 protection against any fiber cut between the remote node and the optical network units (ONUs). In case of such fiber cut, the affected ONU can still communicate with the optical line terminal by rerouting the wavelength channels via the adjacent ONU.
An Investigation of the Curl-Down Test as a Measure of Abdominal Strength (1967)

Abstract Sixty freshmen college women were given the 30-second and 60-second curl-down tests and two trials on the Elgin Multiple Angle testing unit. Standing and sitting height and weight measurements were also recorded. Analysis of the data showed (a) no significant relationship of the curl-down scores to the physical dimensions, (b) a .78 reliability coefficient on the 30-second tests, (c) dynamometer scores positively related (r=.44 and r=.32) to the 30-second and 60-second scores respectively. A test between the correlated r's resulted in a significant t of 3.46 and a significant t (8.47) between correlated means on the split halves of the 60-second test. The 60-second test was given to another 72 subjects with scores recorded each 10 seconds. After the fourth 10-seconds interval, the scores radically decreased, therefore a 40-second curl-down test is recommended.
Biological and clinical aspects of ABO blood group system (2008)

The ABO blood group was discovered in 1900 by Austrian scientist, Karl Landsteiner. At present, the International Society of Blood Transfusion (ISBT) approves as 29 human blood group systems. The ABO blood group system consists of four antigens (A, B, O and AB). These antigens are known as oligosaccharide antigens, and widely expressed on the membranes of red cell and tissue cells as well as, in the saliva and body fluid. The ABO blood group antigens are one of the most important issues in transfusion medicine to evaluate the adaptability of donor blood cells with bone marrow transplantations, and lifespan of the hemocytes.This article reviews the serology, biochemistry and genetic characteristics, and clinical application of ABO antigens.
