Evaluations of HCFC-123 and HCFC-141b as Potential Blowing Agents for Polyurethane/Polyisocyanurate Rigid Foam Laminate Insulation (1989)

Trichlorofluoromethane, commonly called CFC-11, is the primary blowing agent used in the production of polyurethane (PUR) or polyisocyanurate (PIR) rigid foams for laminate insulation. CFC-11 is also a member of a class of chlo rofluorocarbons called "hard CFC's," which are believed to contribute to the destruc tion of the earth's protective ozone layer located in the stratosphere above the Antarc tic. Two possible CFC-11 replacements for rigid laminate insulation production with lower ozone depletion potentials than CFC-11 have been identified. They are CF3CHCL2 (HCFC-123) and CCL2FCH3 (HCFH-141b). Many properties of the foam contribute to the overall effectiveness of the laminated insulation product when applied as part of a roof or in a sheathing application Some of these properties in clude foam density, compressive strength, dimensional stability, thermal conductiv ity, and performance in specified flammability tests (ASTM-E84 or UL-723). In order to be a viable replacement for CFC-11, utilizing current laminate chemistry and processing technology, HCFC-123 or HCFC-141b must produce foams that give equivalent or better values than CFC-11 blown foams for the properties listed above. Continuous laminate production evaluations of HCFC-123 abd HCFC-141b were conducted at the North Haven Laboratories of The Dow Chemical Company in a typical rigid laminate formulation to determine the viability of these chemicals as replacement blowing agents of CFC-11. These evaluations included a control run of 100% CFC-11 and blends of HCFC-123 or HCFC-141b with CFC-11. Analyses include reactivity profiles, physical property measurements, initial and aged thermal conductivities, and flammability performance as measured by the UL-723 Tunnel Test.
Prognostic significance of DNA ploidy and proliferative indices in patients with nasopharyngeal carcinoma. (2002)

DNA ploidy, SPF, and PF could be predictors of prognosis for NPC patients. Thus, determination of these indices can be used as an additional reference for clinicians to identify a poor prognostic NPC individual together with clinic pathological parameters.
Graph cube (2011)

We consider extending decision support facilities toward large sophisticated networks, upon which multidimensional attributes are associated with network entities, thereby forming the so-called multidimensional networks. Data warehouses and OLAP (Online Analytical Processing) technology have proven to be effective tools for decision support on relational data. However, they are not well-equipped to handle the new yet important multidimensional networks. In this paper, we introduce Graph Cube, a new data warehousing model that supports OLAP queries effectively on large multidimensional networks. By taking account of both attribute aggregation and structure summarization of the networks, Graph Cube goes beyond the traditional data cube model involved solely with numeric value based group-by's, thus resulting in a more insightful and structure-enriched aggregate network within every possible multidimensional space. Besides traditional cuboid queries, a new class of OLAP queries, crossboid, is introduced that is uniquely useful in multidimensional networks and has not been studied before. We implement Graph Cube by combining special characteristics of multidimensional networks with the existing well-studied data cube techniques. We perform extensive experimental studies on a series of real world data sets and Graph Cube is shown to be a powerful and efficient tool for decision support on large multidimensional networks.
Stickler-like syndrome due to a dominant negative mutation in the COL2A1 gene (1998)

The type II collagenopathies include a wide spectrum of phenotypes ranging from mild spondylo epiphyseal dysplasia (SED) to severe achondrogenesis/hypochondrogenesis. Several attempts have been made at providing phenotype-genotype correlations in this group of disorders. In this report we discuss a South African family in which four members have a phenotype resembling Stickler syndrome type 1. Ocular problems and conductive deafness predominate, while skeletal changes resemble those of a mild form of multiple epiphyseal dysplasia (MED). In distinction to the classical form of Stickler syndrome, the affected persons have stubby digits. DNA analysis of the exons of the COL2A1 gene documented a C-T transversion in exon 39, resulting in an Arg704Cys substitution in the triple helical domain of the type II collagen peptide; this nontermination mutation may be indicative of further heterogeneity in the Stickler group of disorders or of a new syndrome amongst the type II collagenopathies.

A sequence of subset conjugate graduate optimization based super-resolution algorithm is proposed for super-resolution,where image registration algorithm is used to estimate the displacement and rotation between different low-resolution images,prior knowledge is used for regulation and building the cost function,and the high-resolution image is estimated by using sequence subset conjugate graduate optimization algorithm.Simulation results demonstrate that the method can realize the super-resolution with 15% memory reduction and 20% high speed promotion.
Hierarchical filtering method for content-based music retrieval via acoustic input (2001)

This paper presents an implementation of a content-based music retrieval system that can take a user's acoustic input (8-second clip of singing or humming) via a microphone and then retrieve the intended song from a database containing over 3000 candidate songs. The system, known as Super MBox, demonstrates the feasibility of real-time music retrieval with a high success rate. Super MBox first takes the user's acoustic input from a microphone and converts it into a pitch vector. Then a hierarchical filtering method (HFM) is used to first filter out 80% unlikely candidates and then compare the query input with the remaining 20% candidates in a detailed manner. The output of Super MBox is a ranked song list according to the computed similarity scores. A brief mathematical analysis of the two-step HFM is given in the paper to explain how to derive the optimum parameters of the comparison engine. The proposed HFM and its analysis framework can be directly applied to other multimedia information retrieval systems. We have tested Super MBox extensively and found the top-20 success rate is over 85%, based on a dataset of about singing/humming 2000 clips from people with mediocre singing skills. Our studies demonstrate the feasibility of using Super MBox as a prototype for music search engines over the Internet and/or query engines in digital music libraries.
A 3 GHz transimpedance OEIC receiver for 1.3-1.55 mu m fiber-optic systems (1990)

A high-performance metal-semiconductor-metal high-electron-mobility transistor (MSM-HEMT) transimpedance photoreceiver fabricated using OMCVD-grown InAlAs/InGaAs heterostructures on an InP substrate is discussed. This is the first demonstration of a monolithically integrated receiver amplifier that incorporates a cascode amplifier stage and a Schottky diode level-shifting stage implemented on InP-based optoelectronic integrated circuit (OEIC) photoreceivers. The transimpedance amplifier has an open-loop gain of 5.7 and a bandwidth of 3.0 GHz, which represent the highest gain and the highest speed performance reported for 1.3-1.55- mu m-wavelength OEIC receivers.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
LOMAC: Low Water-Mark integrity protection for COTS environments (2002)

We hypothesize that a form of kernel-resident access control based integrity protection can gain widespread acceptance in commercial off-the-shelf (COTS) environments, provided that it couples some useful protection with a high degree of compatibility with existing software, configurations, and practices. To test this hypothesis, we have developed a highly compatible free open-source prototype called LOMAC, and released it on the Internet. LOMAC is a dynamically loadable extension for COTS Linux kernels that provides integrity protection based on Low Water-Mark access control. We present a classification of existing access control models with regard to compatibility, concluding that models similar to Low Water-Mark are especially well suited to high-compatibility solutions. We also describe our practical strategies for dealing with the pathological cases in the Low Water-Mark model's behavior which include a small extension of the model, and an unusual application of its concepts.
In-Vehicle Brake System Temperature Model (2012)

The brakes system is critical with respect to vehicle safety. One situation during which\nthe brake system is put to the test is an Alpine descent. Such a descent causes very high\nbrake system temperatures and may even induce brake fluid vaporization. In following\nreport an In-Vehicle Brake System Temperature Model is developed and tested. This\nmodel makes use of the information that is available on the vehicle CAN-bus in order to\nestimate the temperature of the brake system and detect the risk of brake fluid\nvaporization. Implementing such a model in production vehicles would improve vehicle\nsafety and in the long run allow downsizing of the brake system without giving in on\nany safety margins. Firstly, possible approaches for estimating the amount of kinetic energy that is\nconverted into heat by the brake system are investigated. A Feed-Forward model is\ndeveloped that uses the pressure in the primary hydraulic circuit as input. The problem\nwith such a Feed-Forward Model is that the friction coefficient is variable. A Feed-Back\nmodel that uses the vehicle deceleration as input gives better results. The challenge in\nthis approach lies in the fact that not all required inputs for the Feed-Back Model are\nknown. Secondly, the Temperature Estimation Model is developed. This is composed of models\nof different parts of the brake system which are combined and matched to the\nmeasurements. The brake disc is modeled as a lumped mass. The brake pad is modeled\nas a Finite Difference Thermal Model. The fluid and surrounding caliper are modeled as\none lumped mass which receives its heat through conduction from the brake pad and\nspreads the heat into the surroundings by means of convection. Finally, for the Human Machine Interface, several active and passive intervention\nconcepts are proposed. One important challenge to take into account is the uncertainty\nin the brake fluid boiling temperature, which decreases over the course of time due to\nbrake hygroscopic effects.

A communication model in multilevel security network using quantum key (2015)

The integrity and confidentiality of the multilevel security communication are guaranteed by using the key obtained from key negotiation process. To ensure the safety of this process is very important. The quantum key distribution process is unconditionally secure. This paper uses this process to distribute the authentication keys and the session keys, which are used in IPSec process. Thus, the method to realize multilevel secure communication by using quantum key and IPSec is given. It adds a field to implement the control strategy based on the security of the packet, uses a key effective time to meet the different security requirements, and uses the “one-time-pad” algorithm to provide unconditional security. After the rules of using keys are given, the process of transmitting data packets is described.

Optimizing etch uniformity for alternating aperture phase shift masks on Etec Systems' Tetra photomask etch system (2002)

A simple method for minimizing the glass etch non-uniformity in the Etec Systems' Tetra etch tool will be presented along with etch rate performance stability results. In this triple etch process, the final phase uniformity was improved from ± 5 ° to ± 1.3 ° phase shift at 248 nm without changing either processing chemistry or any other process parameters. The procedure used to obtain this improved uniformity as well as maps illustrating the depth distribution over the plate after each step will be given.
Heat of vaporization spectrometer (1979)

Multilayer desorption measurements of various substances adsorbed on a stainless-steel substrate are found to exhibit desorption profiles consistent with a zeroth-order desorption model. The singleness of the desorption transients together with their narrow peak widths makes the technique ideally suited for a heat of vaporization spectrometer for either substance analysis or identification.
Modified atmospheres during storage and transport for bitter pit reduction in ‘Cox's Orange Pippin’ apple (1989)

Abstract Modified atmospheres (MA) generated within cartons of ‘Cox's Orange Pippin’ apples containing 25 µm thick polybags with 50 microperforations, effectively reduced bitter pit and maintained quality in fiuit from a range of growers after storage at 1 ± °C for 6 weeks and 1 week at ambient temperatures. A pilot‐scale trial transported to the United Kingdom indicated that the polybag system could be utilised commercially for export of apples in MA conditions. Large scale evaluation of the system on fruit from a number of growers confirmed the effectiveness of the system but suggested that, where background levels of bitter pit exceed 20–30%, neither MA nor commercial postharvest calcium treatments can reduce bitter pit levels to less than 5%. A disorder similar to brown‐heart developed in fruit that had been vacuum‐infiltrated with CaCl 2 followed by storage in microperforated polybags, indicating that this combined treatment would not be commercially viable.
Nonalcoholic fatty liver disease. (2002)

Nonalcoholic fatty liver disease (NAFLD) encompasses a broad clinicopathologic spectrum ranging from simple steatosis to nonalcoholic steatohepatitis (NASH), which may advance to cirrhosis and end-stage liver disease. Steatosis alone does not appear to be progressive. The prevalence of NAFLD averages 20% and that of NASH, 2% to 3%, making these conditions the most common liver diseases in the United States. NAFLD is associated with insulin resistance, which may be evident clinically with obesity, type 2 diabetes mellitus, and hypertriglyceridemia. The pathogenesis of NAFLD consists of hepatic fat accumulation and oxidative stress with formation of free radicals. The clinical diagnosis is based on the presence of the insulin resistance syndrome and exclusion of alcohol abuse as well as viral, autoimmune, genetic, and drug-induced liver diseases. Liver biopsy is essential for diagnosis but may not be necessary for clinical management. Treatment is aimed at correcting the risk factors for NAFLD and using potentially hepatoprotective agents. Ursodeoxycholic acid and betaine appear particularly promising in early trials.
Parametrized End-to-End Scenario Generation Architecture for Autonomous Vehicles (2018)

Validation of highly automated or autonomous vehicles is still a major challenge. One main reason is the need to identify the uncountable potential situations in which the vehicle should be evaluated. Even when they are completely identified, the full-coverage of all these situations is not possible in real-world tests. Virtual validation however can be used to generate infinitesimally changing cases for testing. Nevertheless, the main challenge then becomes the collection and description of realistic test scenarios. This paper proposes an end-to-end approach for scenario generation from various sources. A flexible database structure enables fast and efficient querying that is used to generate an extensive set of test cases. The proposed schema is evaluated end-to-end-from scenario to test case generation to automated simulation and data gathering-populated by a data source based on the experience gained through real world tests. The proposed approach is a further step towards more efficient testing of autonomous functions.
One-Pot Room Temperature Synthesis of Cu<sub>2</sub>O/Ag Composite Nanospheres with Enhanced Visible-Light-Driven Photocatalytic Performance (2014)

Cu2O/Ag composite nanospheres (CNSs) with tunable Ag coverage and optical properties have been prepared based on a one-pot room temperature method by adding AgNO3 solution to fresh Cu2O nanosphere-produced mother solution in various ratios. Ag+ ions can be reduced by the primary Cu2O nanospheres in the acidic solution, and the obtained Ag nanoparticles can be deposited on the surfaces of the Cu2O nanospheres. The photocatalytic activity of Cu2O/Ag CNSs has been evaluated for photodegradation of methyl orange (MO) dye under visible-light irradiation, which demonstrates that Cu2O nanospheres with Ag loading exhibit significantly enhanced photocatalytic activity compared with pure Cu2O counterparts, and their photocatalytic properties depend on the coverage density of Ag nanoparticles. The enhanced photocatalytic activity can be attributed to the deposition of Ag acting as electron sinks to prevent the recombination of the photogenerated electrons and holes, and the plasmon resonances of the Ag nanoparticles generating more electron–hole pairs in the semiconductor.
Geometry effects on the NBTI degradation of PMOS transistors (2008)

This paper presents the real impact of transistor geometry on the NBTI degradation. IDsat degrades faster longer transistors, which is attributed to the small relative saturation region with respect to the total channel length. Narrow transistor degradation is accelerated by the contribution of the edge of the active region. Transistor lifetime depends on their width in a logarithmic way. It also explain the instability observed in measurements on small area transistors by the impact of very few defects relaxation during the measurements. Low voltage P-channel MOSFETs with various channel lengths and widths are used in this study. According to this work, the worst case for NBTI degradation would be a narrow and long transistor.
A Low-Latency GTS Strategy in IEEE802.15.4 for Industrial Applications (2008)

For industrial applications, real-time performance is a critical issue of wireless sensor network. IEEE802.15.4 protocol has greater potential compared with other protocols. However, it can¿t meet the strict requirements of real-time performance in industrial environment. After analyzing the demands of versatile applications in industrial environment and guaranteed time slots (GTS) mechanism in the IEEE802.15.4, this paper presents a new proposal including scheduling and publishing mechanism of GTS, which can significantly reduce the delay and improve the real-time performance of the network.
Empirical Characteristics of Dynamic Trading Strategies: The Case of Hedge Funds (1997)

This article presents some new results on an unexplored dataset on hedge fund performance. The results indicate that hedge funds follow strategies that are dramatically different from mutual funds, and support the claim that these strategies are highly dynamic. The article finds five dominant investment styles in hedge funds, which when added to Sharpe’s (1992) asset class factor model can provide an integrated framework for style analysis of both buy-and-hold and dynamic trading strategies.
A primary study on the solid-state cultivation of lactobacillus acidophilus (2002)

The growth situation of Lactobacillus acidophilus in four different solid media(soybean dregs,wheat bran,minced tar and cellulose) was studied.The results showed as follows:1)Soybean dregs media was the most suitable media,the density of the living cell could achieve 1.645*10~(9)cfu/g.It was also better than three different liquid different media(soybean milk,milk,MRS);2)The suitable water content of the soybean media was about 75%;3)CaCO_(3) was used to neutralize the acid produced by the Lactobacillus cell,while citric acid-Na_(2)HPO_(4) buffer(pH 6.8) were used instead of water for preparation of solid media,the number of Lactobacillus increased to 2.124*10~(9) cfu/g.
Timing acquisition for low-SNR data storage channels (2003)

As magnetic data storage densities are pushed toward Tb/in/sup 2/ and beyond, advanced signal-detection algorithms are being suggested to cope with the expected lower signal-to-noise ratios (SNRs). However, at low SNR, loss of lock will frequently occur in the current timing-recovery system. This paper illustrates that inadequate timing acquisition is the major cause for loss of lock in hard disk drives. Motivated by the digital zero phase start (DZPS) technique, a digital zero frequency/phase start (DZF/PS) technique is proposed to quickly reduce the initial frequency and phase errors. Kalman filter-based acquisition can be used subsequently to fine-tune acquisition based on the buffered symbol-rate samples of a preamble readout signal. Numerical simulations show that DZF/PS can reduce preamble length significantly (when used in acquisition) compared with DZPS.
