Subjective evaluation of MPEG-4 video codec proposals: Methodological approach and test procedures (1997)

A new audio-visual coding standard, MPEG-4, is currently under development. MPEG-4 will address not only compression, but also completely new audio-video coding functionalities related to content-based interactivity and universal access. As part of the MPEG-4 standardization process, in November, 1995 assessments were performed on technologies proposed for incorporation in the standard. These assessments included formal subjective tests, as well as expert panel evaluations. This paper describes the MPEG-4 video formal subjective tests. Since MPEG-4 addresses new coding functionalities, and also operates at bit-rates lower than ever subjectively tested before on a large scale, standard ITU test methods were not directly applicable. These methods had to be adapted, and even new test methods devised, for the MPEG-4 video subjective tests. We describe here the test methods used in the MPEG-4 video subjective tests, how the tests were carried out, and how the test results were interpreted. We also evaluate the successes and shortcomings of the MPEG-4 video subjective tests, and suggest possible improvements for future tests. The MPEG-4 video subjective tests were successful, providing the MPEG community with critical information to guide in the selection of technologies for inclusion in the video part of the MPEG-4 standard.
Progress in Studies on Anticancer Components from Snake Venom (2003)

The latest research progress on anticancer components of snake venom was introduced. The components could be classified into cytotoxins, disintegrins and apoptosis inducers based on their anticancer mechanisms and a variety of anticancer components purified from different snake venoms were introduced.
Two-Level Cache Performance for Multiprocessors (1993)

For shared bus multiprocessors operated in multiprogramming mode, the addition of second-level caches tends to significantly increase system performance. Trace-driven simulation was employed to obtain performance measurements over a range of system parameters, with the cache sizes at both levels being the parameters of most interest. For both light and heavy system loading, the addition of second-level caches was found to boost system performance. For heavily loaded multiprocessor cases, the workload-averaged percentage increases in performance ranged from 187% with 32k byte first-level caches to 507% with 4k byte first-level caches when 128k byte second- level caches were added. The main memory configuration and number of processors largely dictates the performance of a shared bus multiprocessor running in multiprogramming mode. The addition of larger second-level caches to the system results in increased system performance over a range of system configurations and workloads.
Maternal serum screening of fetal chromosomal abnormalities by AFP, UE3, hCG and free-beta hCG. Prospective and retrospective results. (1996)

We have conducted a prospective study to ascertain the reliability of the triple test in detecting aneuploid fetuses in a Mediterranean, pregnant population. 2978 singleton pregnancies in the 15-22 completed week's gestational range were enrolled in this study between January 1992 and June 1994. The measurements of the analytes AFP, hCG and UE3 in the maternal serum combined with maternal age in a multivariate risk approach were utilized to detect pregnancies at increased risk (cut of > or = 1:270) to undergo prenatal diagnosis by amniocentesis. This screening was preferentially reserved to young patients (median age of the population 29 years). 212 pregnancies resulted screen positive to triple test and 178 accepted fetal chromosomal analysis. Three Down's syndrome, a Turner 45XO and a triploidy 69XXY were detected in the sample undergoing prenatal diagnosis. One aneuploid pregnancy (Down's syndrome) was recorded in the population with negative result (risk < 1:270). As part of this study we have subsequently compared the sensitivity of the test substituting total hCG with free-beta marker in samples from aneuploid pregnancies (16 cases) and unaffected pregnancies (300 cases). The detection rate for the two combinations was identical (81%) as well as the false positive rate (5.7% versus 5.3%) derived from the normal samples. All together these combined results of our study support the increasing call for triple test in screening programmes and indicate that further data be collected before recommending the replacement of total hCG with free-beta analyte.
Modulation spectrum-constrained trajectory training algorithm for GMM-based Voice Conversion (2015)

This paper presents a novel training algorithm for Gaussian Mixture Model (GMM)-based Voice Conversion (VC). One of the advantages of GMM-based VC is computationally efficient conversion processing enabling to achieve real-time VC applications. On the other hand, the quality of the converted speech is still significantly worse than that of natural speech. In order to address this problem while preserving the computationally efficient conversion processing, the proposed training method enables 1) to use a consistent optimization criterion between training and conversion and 2) to compensate a Modulation Spectrum (MS) of the converted parameter trajectory as a feature sensitively correlated with over-smoothing effects causing quality degradation of the converted speech. The experimental results demonstrate that the proposed algorithm yields significant improvements in term of both the converted speech quality and the conversion accuracy for speaker individuality compared to the basic training algorithm.
FIPOS (Full Isolation by Porous Oxidized Silicon) technology and its application to LSI's (1984)

Processing steps of FIPOS (Full Isolation by Porous Oxidized Silicon) technology and its application to LSI's are presented, FIPOS technology realizes a silicon-on-insulator structure, utilizing thick porous oxidized silicon and donors produced by proton implantation. New processing steps are proposed which provides small surface step and are suitable for LSI fabrication. Formation conditions of thick porous oxidized silicon are established by density control technique for porous silicon using a newly developed anodization system. CMOS devices are fabricated in isolated silicon layers and it is shown that the characteristics of n-channel and p-channel MOSFETS's are sufficient for application to CMOS LSI's. A FIPOS/CMOS logic array with 1.3K gate is successfully fabricated, which shows a higher speed and lower power dissipation than the gates fabricated by bulk CMOS technology. These results indicate that FIPOS technology is very useful for realizing high-performance CMOS LSI's.
Mass spectrometry imaging with high resolution in mass and space (2013)

Mass spectrometry (MS) imaging links molecular information and the spatial distribution of analytes within a sample. In contrast to most histochemical techniques, mass spectrometry imaging can differentiate molecular modifications and does not require labeling of targeted compounds. We have recently introduced the first mass spectrometry imaging method that provides highly specific molecular information (high resolution and accuracy in mass) at cellular dimensions (high resolution in space). This method is based on a matrix-assisted laser desorption/ionization (MALDI) imaging source working at atmospheric pressure which is coupled to an orbital trapping mass spectrometer. Here, we present a number of application examples and demonstrate the benefit of 'mass spectrometry imaging with high resolution in mass and space.' Phospholipids, peptides and drug compounds were imaged in a number of tissue samples at a spatial resolution of 5-10 μm. Proteins were analyzed after on-tissue tryptic digestion at 50-μm resolution. Additional applications include the analysis of single cells and of human lung carcinoma tissue as well as the first MALDI imaging measurement of tissue at 3 μm pixel size. MS image analysis for all these experiments showed excellent correlation with histological staining evaluation. The high mass resolution (R = 30,000) and mass accuracy (typically 1 ppm) proved to be essential for specific image generation and reliable identification of analytes in tissue samples. The ability to combine the required high-quality mass analysis with spatial resolution in the range of single cells is a unique feature of our method. With that, it has the potential to supplement classical histochemical protocols and to provide new insights about molecular processes on the cellular level.
Cleaning Products and Air Fresheners: Emissions and ResultingConcentrations of Glycol Ethers and Terpenoids (2005)

Experiments were conducted to quantify emissions and concentrations of glycol ethers and terpenoids from cleaning product and air freshener use in a 50-m{sup 3} room ventilated at {approx}0.5 h{sup -1}. Five cleaning products were applied full-strength (FS); three were additionally used in dilute solution. FS application of pine-oil cleaner (POC) yielded 1-h concentrations of 10-1300 {micro}g m{sup -3} for individual terpenoids, including {alpha}-terpinene (90-120), d-limonene (1000-1100), terpinolene (900-1300), and {alpha}-terpineol (260-700). One-hour concentrations of 2-butoxyethanol and/or dlimonene were 300-6000 {micro}g m{sup -3} after FS use of other products. During FS application including rinsing with sponge and wiping with towels, fractional emissions (mass volatilized/dispensed) of 2-butoxyethanol and d-limonene were 50-100% with towels retained, {approx}25-50% when towels were removed after cleaning. Lower fractions (2-11%) resulted from dilute use. Fractional emissions of terpenes from FS use of POC were {approx}35-70% with towels retained, 20-50% with towels removed. During floor cleaning with dilute solution of POC, 7-12% of dispensed terpenes were emitted. Terpene alcohols were emitted at lower fractions: 7-30% (FS, towels retained), 2-9% (FS, towels removed), and 2-5% (dilute). During air-freshener use, d-limonene, dihydromyrcenol, linalool, linalyl acetate, and {beta}-citronellol were emitted at 35-180 mg d{sup -1} over three days while air concentrations averaged 30-160 {micro}g m{sup -3}.
Autosomal Recessive Polycystic Kidney Disease: A Hepatorenal Fibrocystic Disorder With Pleiotropic Effects (2014)

Autosomal recessive polycystic kidney disease (ARPKD) is an important cause of chronic kidney disease in children. The care of ARPKD patients has traditionally been the realm of pediatric nephrologists; however, the disease has multisystem effects, and a comprehensive care strategy often requires a multidisciplinary team. Most notably, ARPKD patients have congenital hepatic fibrosis, which can lead to portal hypertension, requiring close follow-up by pediatric gastroenterologists. In severely affected infants, the diagnosis is often first suspected by obstetricians detecting enlarged, echogenic kidneys and oligohydramnios on prenatal ultrasounds. Neonatologists are central to the care of these infants, who may have respiratory compromise due to pulmonary hypoplasia and massively enlarged kidneys. Surgical considerations can include the possibility of nephrectomy to relieve mass effect, placement of dialysis access, and kidney and/or liver transplantation. Families of patients with ARPKD also face decisions regarding genetic testing of affected children, testing of asymptomatic siblings, or consideration of preimplantation genetic diagnosis for future pregnancies. They may therefore interface with genetic counselors, geneticists, and reproductive endocrinologists. Children with ARPKD may also be at risk for neurocognitive dysfunction and may require neuropsychological referral. The care of patients and families affected by ARPKD is therefore a multidisciplinary effort, and the general pediatrician can play a central role in this complex web of care. In this review, we outline the spectrum of clinical manifestations of ARPKD and review genetics of the disease, clinical and genetic diagnosis, perinatal management, management of organ-specific complications, and future directions for disease monitoring and potential therapies.
Gadolinium blocks low- and high-threshold calcium currents in pituitary cells (1990)

The inhibition of L- and T-type Ca2+ currents by Gd3+ was studied in the rat pituitary GH4C1 cell line. In whole cell patch recordings, Gd3+ at concentrations of 50 nM to 5 microM blocked Ca2+ current through L-type channels. Block was promoted by prolonged channel activation. With 4.5-s test pulses to + 10 mV, Gd3+ at concentrations as low as 200 nM produced near-complete block of L current. At higher Gd3+ concentrations (5 microM), complete block occurred with short test pulses and appeared to be independent of channel activation. Gd3+ also blocked current through low-threshold T channels in GH4C1 cells. Two other trivalent elements, La3+ and Y3+, blocked L-type Ca2+ channels in GH4C1 cells with potency similar to Gd3+. These results indicate that these trivalent cations are effective nonselective inhibitors of both low- and high-threshold Ca2+ channels in endocrine cells. In this regard, they are among the most potent inorganic Ca2+ antagonists yet discovered.
Development and Qualification of Monolithically Assembled Modules for Back Contact PV Cells (2010)

Back-contact silicon solar cells enable new concepts for the module design and assembly. Monolithic module assembly refers to a process whereby the solar cell circuit and the module encapsulation are accomplished during the lamination step. This paper describes the advantages of MMA, extension of MMA to multiple back-contact cell configurations, progress in design and qualification of commercial-scale modules based on MMA, and first results on pilot-scale production of MMA modules.
Impedance measurements of a HOM-damped low power model cavity (2004)

In the frame of a European Community funded project a higher order mode (HOM) damped normal conducting 500 MHz cavity is under development optimized for the use in 3rd generation storage ring light sources. The relevant HOM-impedances have been measured with a fully scaled low power model made from aluminium. By using a cutoff frequency of 615 MHz for the damping waveguides we have found a good compromise between the preservation of the accelerating mode impedance and the efficient broadband damping of HOM's. Detailed experimental results are presented and compared with numerical simulations.
Tension-Controlled Active Compression Garment for Treatment of Orthostatic Intolerance (2018)

Medical compression garments are used to treat lymphatic disorders or conditions of poor venous return (e.g. orthostatic intolerance). Conventional compression garments, namely elastic compression sleeves and inflatable compression systems, may aid in relief of these conditions but are also limited in usability. Fixed levels of compression in elastic materials may induce challenges in donning/doffing, complicating patient compliance [1]. Compression levels in inflatable systems are customizable, but these garments are also bulky and require a tethered inflation source [2]. We are interested in developing easy-to-don/-doff compression garments using shape memory alloy (SMA) coil actuators that contract with heat from an applied current which can be wrapped around the body to apply compressive forces. More specifically, we use a spring coil formation as described by Holschuh et al. [3]. Further developed in the Wearable Technology Lab at the University of Minnesota, our current SMA compression garment (SMA-CG) design improves upon the work of Duvall et al. [4] presented in previous year’s (2017) Design of Medical Devices Conference, representing a year’s evolution in active compression garment design that integrate actuators made with SMA.

On the Geometry of Emergency Service Medical Provision in Cities (1983)

The enormity of many cities today poses special problems for authorities supplying emergency medical services. The scale of the emergency system and variations in the operating conditions rule out some of the traditional methods developed to deal with the complexities involved. In cities the provision of services is affected not only by the daily varying locations of the populations at risk, but also by the prevailing traffic and weather conditions that can hinder ambulance access to the site of an incident or to a treatment facility. The controlling authorities of these services nevertheless like to maintain the highest possible levels of service given the available resources. They are interested in knowing which facilities to open and when, what resources and staffing levels are required, and what the long-term and short-term implications of changing operating conditions and of other unforeseen circumstances are on operating standards. In this paper the authors present research into a set of methods that are designed to assist in finding solutions to these problems or, at least, in understanding how to deal with them. The methods are based on the efficiency of movement in cities, particularly the time it takes to access different locations in different traffic conditions, and on the likelihood of incidents occurring at different times of the day. Initial results are presented based on the London area, but the main conclusions are transferable to many other cities of comparable scale. The distinguishing feature of the methods is that they are based on a type of non-Euclidean geometry that arises from the generalized profiles of the average speeds of traffic flow in cities.
Parental History of Alcoholism and Problem Behaviors in Native‐American Children and Adolescents (2000)

These findings suggest that sons of alcoholics of Mission Indian heritage experience more problems than sons of nonalcoholics, but also suggest that Mission Indian children of alcoholics are not more vulnerable to behavioral problems than children of alcoholic parents of other ethnic backgrounds.
Transverse emittance growth in staged laser-wakefield acceleration (2012)

We present a study on the emittance evolution of electron bunches, externally injected into laser-driven plasma waves using the three-dimensional particle-in-cell (PIC) code OSIRIS. Results show order-of-magnitude transverse emittance growth during the injection process, if the electron bunch is not matched to its intrinsic betatron motion inside the wakefield. This behavior is supported by analytic theory reproducing the simulation data to a percent level. The length over which the full emittance growth develops is found to be less than or comparable to the typical dimension of a single plasma module in current multistage designs. In addition, the analytic theory enables the quantitative prediction of emittance degradation in two consecutive accelerators coupled by free-drift sections, excluding this as a scheme for effective emittance-growth suppression, and thus suggests the necessity of beam-matching sections between acceleration stages with fundamental implications on the overall design of staged laser-wakefield accelerators.
THE POSITIVE ANALYSIS ABOUT THE CONDITION OF CHINESE TECHNOLOGY GAIN FDI (2015)

The technical level in 21st century will directly decide the international competition ability of a country and become the core factor which the international competition will subdue. Using the reverse effect of shift of technology in foreign investment, a company gains advanced technology through foreign investment and shift it to the investment country, which movement we call it technical gain FDI. Various countries in the world especially the developing countries, such as China, its research level and the environment can’t adapt the demand of economic globalization. So it is a realistic choice to the developing countries to develop technology gain investment and combine with the other foreign investment to gain the advanced technology.

Direct measurement of viraemia in patients infected with HIV‐1 and its relationship to disease progression and zidovudine therapy (1991)

Cell-free human immunodeficiency virus type-1 (HIV-1) was precipitated from archival serum with polyethylene glycol (PEG), and HIV-1 RNA was detected and quantified by reverse transcription and amplification in a nested polymerase chain reaction (PCR). The assay of end-point dilutions cDNA in nested PCRs allowed an estimation of the minimum RNA copies per unit volume of serum. RNA titres correlated with the classification of HIV-1 infection by CDC disease groups (30 patients). The geometric mean titres of HIV-1 serum RNA from patients grouped by disease stage gave minimum estimates of 340 and 400 virions per millilitre of serum in CDC groups II and III (n = 6 and 10, respectively) and 4,240 virions per millilitre in CDC group IV (n = 14). An overall fall in viral titre measured in this way was observed in 3 patients during zidovudine treatment. HIV-1 titres increased in a further 4 patients when therapy was interrupted, stopped, or complicated by secondary infection.
