Characterization of sputtered yttria-stabilized zirconia thin film and its application to a metal-insulator-semiconductor structure (1992)

An rf-sputtered yttria-stabilized zirconia (YSZ) thin film was characterized as to its structural and electrical properties. Then a metal-insulator-semiconductor (MIS) structure incorporating it as a part of a multi-insulator was investigated particularly for use in a field-effect transistor (FET)-type oxygen sensor. The YSZ film deposited on a Si3N4 film was found to be a cubic structure based on x-ray diffraction and reflective high-energy electron diffraction analyses. As cracks were formed at 800 °C, annealing treatment of the film should be carried out below that temperature. The leakage current of the sputtered YSZ film was smaller than 2×10−7 A/cm2 in the applied voltage range 0–5 V, which was comparable to that of the calcia-stabilized zirconia film used for a potentiometric oxygen sensor. The dielectric constant of the sputtered YSZ film was 16±2 at 105 Hz. The minimum loss tangent was 0.01. The frequency dispersion of the dielectric constant and loss tangent were improved by annealing treatment at temperatures lower than 400 °C. The capacitance-voltage (C-V) characteristics of the MIS structure incorporating the YSZ film showed hysteresis and positive shifts of the flatband voltages as compared with those of the MIS structure without the YSZ film. The hysteresis was considered to be due to the movement of charged species such as oxygen ions and/or electrons in the YSZ film, which would cause an unstable response of the FET-type oxygen sensor.
Energy-Efficient Virtual Machines Consolidation in Cloud Data Centers Using Reinforcement Learning (2014)

Dynamic consolidation techniques optimize resource utilization and reduce energy consumption in Cloud data centers. They should consider the variability of the workload to decide when idle or underutilized hosts switch to sleep mode in order to minimize energy consumption. In this paper, we propose a Reinforcement Learning-based Dynamic Consolidation method (RL-DC) to minimize the number of active hosts according to the current resources requirement. The RL-DC utilizes an agent to learn the optimal policy for determining the host power mode by using a popular reinforcement learning method. The agent learns from past knowledge to decide when a host should be switched to the sleep or active mode and improves itself as the workload changes. Therefore, RL-DC does not require any prior information about workload and it dynamically adapts to the environment to achieve online energy and performance management. Experimental results on the real workload traces from more than a thousand PlanetLab virtual machines show that RL-DC minimizes energy consumption and maintains required performance levels.

Dissipation Loss in Multiple-Coupled-Resonator Filters (1959)

This paper examines the effect of dissipation on the response of multiple-coupled-resonator filters designed from lossless prototype low-pass filters. A simple approximate formula makes possible the computation of center-frequency loss in terms of bandwidth, unloaded Q of the resonators, and the parameters of the prototype filter. It is shown how the insertion loss elsewhere in the pass band and stop band may be computed from the prototype filter after modifying its circuit to take account of dissipation in the resonators. The computational techniques are used to compare several symmetrical designs with each other and with unsymmetrical designs having exact maximally-flat and equal-ripple response in the presence of dissipation. It is found that the symmetrical designs offer lower pass-band loss than the unsymmetrical designs. It is proven that a symmetrical filter based on an equal-element prototype has minimum-possible center-frequency loss for given unloaded Q and stop-band bandwidth, subject to assumptions that the loss per resonator is small and that the stop-band insertion loss may be determined accurately from the highest-power term of the insertion-loss polynomial.
Performance evaluation of ballistic silicon nanowire transistors with atomic-basis dispersion relations (2005)

In this letter, we explore the band structure effects on the performance of ballistic silicon nanowire transistors (SNWTs). The energy dispersion relations for silicon nanowires are evaluated with an sp3d5s* tight binding model. Based on the calculated dispersion relations, the ballistic currents for both n-type and p-type SNWTs are evaluated by using a seminumerical ballistic model. For large diameter nanowires, we find that the ballistic p-SNWT delivers half the ON-current of a ballistic n-SNWT. For small diameters, however, the ON-current of the p-type SNWT approaches that of its n-type counterpart. Finally, the carrier injection velocity for SNWTs is compared with those for planar metal-oxide-semiconductor field-effect transistors, clearly demonstrating the impact of quantum confinement on the performance limits of SNWTs.

Economic Burden of Occupational Injury and Illness in the United States (2011)

The medical and indirect costs of occupational injuries and illnesses are sizable, at least as large as the cost of cancer. Workers' compensation covers less than 25 percent of these costs, so all members of society share the burden. The contributions of job-related injuries and illnesses to the overall cost of medical care and ill health are greater than generally assumed.
The influence of caging, bedding, and diet on the composition of the microbiota in different regions of the mouse gut (2018)

Countless studies have identified differences between the gut microbiota of humans affected with myriad conditions and healthy individuals, and animal models are commonly used to determine whether those differences are causative or correlative. Recently, concerns have arisen regarding the reproducibility of animal models between institutions and across time. To determine the influence of three common husbandry-associated factors that vary between institutions, groups of weanling mice were placed in either static or ventilated microisolator caging, with either aspen or paperchip bedding, and with one of three commonly used rodent chows, in a fully crossed study design. After thirteen weeks, samples were collected from multiple regions of the gastrointestinal tract and characterized using culture-independent sequencing methods. Results demonstrated that seemingly benign husbandry factors can interact to induce profound changes in the composition of the microbiota present in certain regions of the gut, most notably the cecum, and that those changes are muted during colonic transit. These findings indicate that differences in factors such as caging and bedding can interact to modulate the gut microbiota that in turn may affect reproducibility of some animal models, and that cecal samples might be optimal when screening environmental effects on the gut microbiota.

System for wireless health monitoring (2004)

A telemetric system that can measure physiological parameters in an unobtrusive way and can transmit it for remote monitoring can prove to be quite useful in providing the ambulatory patients with the freedom of mobility while their health is being monitored continuously. Such a system can be equally useful to monitor the vital signs of service personnel e.g. firefighters working in hazardous environment during their course of duty. In this paper a similar system, that has been designed & developed for unobtrusive and continuous health monitoring, is being described. The system uses RF and GSM communication methods to provide the physiological data online in real time.
Visible photoluminescence in crystallized amorphous Si:H/SiN<i>x</i>:H multiquantum-well structures (1992)

Visible photoluminescence has been observed in crystallized a-Si:H/a-SiNx:H multiquantum-well structures at room temperature. The MQW heterostructures consisting of 72 layers were formed by computer controlled plasma-enhanced chemical-vapor deposition method and then crystallized by Ar+ laser annealing technique. The crystallinity and average grain size of the silicon microcrystals were determined by means of Raman and x-ray diffraction spectroscopy. The crystallized samples with well-layer thickness Ls=40 Å showed an intense photoluminescence which is peaked at 2.1 eV with a full width at half-maximum of 0.25 eV. This is consistent with calculations based on the quantum confinement model.

Cyclic Guanidino-Sugars with Low p<i>K</i><sub>a</sub> as Transition-State Analog Inhibitors of Glycosidases:  Neutral Instead of Charged Species Are the Active Forms (1996)

Cyclic guanidino-sugars with different pKa values are designed and synthesized as transition-state analog inhibitors of galactosidases. Characterization of these structures (7, 10, 12) reveals that 7 and 10 are in a pH-dependent equilibrium between a furanose form and a mixture of neutral and protonated tetrahydropyrimidine forms. In contrast, the O-linked guanidino-sugar 12 exists as the tetrahydropyrimidine forms above pH 5. The furanose−tetrahydropyrimidine equilibrium can thus be modulated with the appropriate N-substituent which affects the guanidino-sugar pKa value. Enzymatic inhibition by 7, 10, and 12 is also pH-dependent, indicating that the enzymes recognize the tetrahydropyrimidine form. Evidence is presented to support a dominant role for the uncharged form of the six-membered cyclic guanidino-sugar in the inhibition of galactosidases. Though the inhibition potency is moderate (Ki range 4−50 μM), the use of cyclic guanidino-sugars in the study provides new insights into the mechanism of inhibition of glycosidases.
MECHANICS OF CUTTING AND BORING, PART 4: DYNAMICS AND ENERGETICS OF PARALLEL MOTION TOOLS (1977)

The report deals with the cutting of rock and similar materials by parallel motion tools. It examines cutting forces and energy requirements, taking into consideration tool geometry, wear, operating conditions, and material properties. After an introductory discussion of terminology, some general principles are outlined, and relevant theoretical ideas on metal cutting and rock cutting are reviewed. The next section, which is the heart of the report, reviews experimental data on the magnitudes and directions of cutting forces. There is a graphical compilation of data, including some from obscure or unpublished sources. The variables covered include chipping depth, rake angle, relief angle, side rake, base angle, tool width, tool compliance, tool speed, tool wear, tool interactions, and material properties. The second major part of the report treats the energetics of cutting. It begins with a short discussion of relevant principles, and continues with a compilation and review of experimental data, covering the same independent variables as the force section. The report ends with a concise summary of general behavior for parallel motion tools. (Author)
DNA Vaccination Against Rat Her-2/Neu p185 More Effectively Inhibits Carcinogenesis Than Transplantable Carcinomas in Transgenic BALB/c Mice   (2000)

The ability of vaccination with plasmids coding for the extracellular and the transmembrane domain of the product of transforming rat Her-2/neu oncogene (r-p185) to protect against r-p185(+) transplantable carcinoma (TUBO) cells and mammary carcinogenesis was evaluated. In normal BALB/c mice, DNA vaccination elicits anti-r-p185 Ab, but only a marginal CTL reactivity, and protects against a TUBO cell challenge. Massive reactive infiltration is associated with TUBO cell rejection. In BALB/c mice transgenic for the rat Her-2/neu gene (BALB-neuT), DNA vaccination elicits a lower anti-r-p185 Ab response, no CTL activity and only incompletely protects against TUBO cells, but markedly hampers the progression of carcinogenesis. At 33 wk of age, when control BALB-neuT mice display palpable tumors in all mammary glands, about 60% of immunized mice are tumor free, and tumor multiplicity is markedly reduced. Tumor-free mammary glands still display the atypical hyperplasia of the early stages of carcinogenesis, and a marked down-modulation of r-p185, along with a massive reactive infiltrate. However, BALB-neuT mice protected against mammary carcinogenesis fail to efficiently reject a TUBO cell challenge. This suggests that the mechanisms required for the rejection of transplantable tumors may not coincide with those that inhibit the slow progression of carcinogenesis.
BASIC Zgrass—a sophisticated graphics language for the Bally Home Library Computer (1978)

Home computer users are just now discovering computer graphics. Modest extensions to BASIC allow plotting but not much more. The Bally Home Library Computer, however, has hardware to aid implementation of video games. Custom integrated circuits working on a 160×102 pixel (2 bits per pixel) color television screen allow certain forms of animation in real time. To give this power to the user, BASIC Zgrass has been designed and implemented. It is an extension of BASIC that allows parallel processes, picture objects that move, scale and group together as well as several drawing modes. There are also software controls of a three-voice music synthesizer, interactive input devices, a film camera and an IEEE bus interface. We will concentrate mainly on the language design for making it all easy to learn and use.

Elimination of degradation in the laser output from Ho3+ in sensitized YAG (1973)

At the present time the most efficient insulating crystal laser is α-YAG (Ho3+ in sensitized YAG), but the 2.1-μ cw output from many α-YAG crystals undergoes a degradation under continuous tungsten lamp illumination. With the aid of a series of liquid optical filters, it is shown that degradation is caused by high-energy pump photons. At least three different types of degradation are produced depending on the wavelength of pump radiation, but all may be eliminated with a liquid filter that absorbs radiation below 5000 Å.
The Results of Treatment of two Hundred and Seventy-Three Carcinomas of the Hand (1981)

Squamous carcinoma of the hand behaves more aggressively, and is more difficult to cure by non-surgical means, when it arises in the interdigital clefts or adjacent skin over the metacarpo phalangeal joints.
A feature-based approach to automatic injection mold generation (2000)

This paper presents a feature-based approach to the automatic generation of an injection mold. In the approach, all the molding features of a molded part are recognized first using a universal hint-based feature recognition algorithm, and the optimal parting direction is determined based on the feature model. Then, all the faces related with the parting line are classified into three groups according to the determined parting direction, and two kinds of parting lines are automatically determined by extracting the largest profile of each face group. Finally, the parting surface is generated based on the optimal pacing line, thereafter the mold core and mold cavity are automatically set up by splitting the mold box of the molded part with the generated parting surface. By using recognized molding features, the approach makes it possible to identify all undercuts, to determine internal parting lines and internal parting surfaces, to generate the mold core and cavity of a complex molded part with undercuts as well.
The Potential for Portfolio Diversification in Financial Services (2000)

The Gramm-Leach-Bliley Act sweeps away most of the barriers limiting the affiliation of banks with nonbank financial services providers. The focus now shifts to financial services executives who must decide which combinations provide the best opportunities to increase shareholder wealth. Existing empirical evidence suggests that an important consideration in this decision is the potential gain from portfolio diversification into new activities. The empirical evidence also suggests that the potential for such gain clearly exists. ; This article builds on earlier studies, in particular updating the contribution of Wall, Reichert, and Mohanty (1993). After reviewing studies since the 1993 article of the potential gains from diversification, the authors summarize the legal changes resulting from passage of the Gramm-Leach-Bliley Act. The article then updates the 1993 analysis of return on assets using data from the Internal Revenue Service (IRS) to cover the 1991-97 period and also examines return on equity from 1991 to 1997. ; The new empirical results are consistent with the prior study in finding substantial potential gains from diversification using IRS data. The results also support the earlier finding that the efficient combinations (lowest risk for any given level of return) vary through time, perhaps for reasons such as the macroeconomic environment or technology. For bankers, one positive change in the 1991-97 period over the 1970s and 1980s is that banks have become a larger part of the efficient financial services portfolio.
A scene adaptive hybrid video coding scheme based on the LOT (1998)

Conventional standard video coding schemes based on independent coding of nonoverlapping image blocks produce undesirable effects (blocking effect and color bleeding, etc.) at low bit rate. A hybrid coding scheme evolving from the standard MPEG codec that combines lapped orthogonal transform (LOT) and overlapped block motion compensation and quantization approaches based on human visual system sensitivity is proposed to remove the artifacts. The LOT is applied to compress the resulting prediction errors of the overlapped motion compensation. The LOT coefficients are quantized by a dynamic intra/inter scene adaptive quantizer that is designed according to the human visual system and scene analysis to optimize the decoded image quality. This technique involves automatically deriving the most favorable quantizer matrix from the motion and scene analysis of image sequences and scaling the resulting matrix further by considering the buffer status. If a scene change is detected from the motion information, the proposed adaptive quantization can also help solve the difficulty of the buffer controller and maintain the picture quality as constant as possible. Performance of the proposed hybrid coding scheme with scene adaptive quantizer is demonstrated by computer simulations using standard test sequences and compared to that of the conventional MPEG-2 coding schemes. Subjective and objective tests show that image quality is improved considerably and the required bit rate is much less than that of the conventional method. Particularly, the image quality can be kept almost consistent, and the undesirable artifacts are reduced considerably.
