Twelve‐Year Dynamics and Rainfall Thresholds for Alternating Creep and Rapid Movement of the Hooskanaden Landslide From Integrating InSAR, Pixel Offset Tracking, and Borehole and Hydrological Measurements (2020)

Abstract The Hooskanaden landslide is a large (~600 m wide × 1,300 m long), deep (~30 – 45 m) slide located in southwestern Oregon. Since 1958, it has had five moderate/major movements that catastrophically damaged the intersecting U.S. Highway 101, along with persistent slow wet‐season movements and a long‐term accelerating trend due to coastal erosion. Multiple remote sensing approaches, borehole measurements, and hydrological observations have been integrated to interpret the motion behaviors of the slide. Pixel offset tracking of both Sentinel‐1 and Sentinel‐2 images was carried out to reconstruct the 3‐D displacement field of the 2019 major event, and the results agree well with field measurements. A 12‐year displacement history of the landslide from 2007 to 2019 has been retrieved by incorporating offsets from Light Detection and Ranging (LiDAR) digital elevation model (DEM) gradients and Interferometric Synthetic Aperture Radar (InSAR) processing of ALOS and Sentinel‐1 images. Comparisons with daily/hourly ground precipitation reveal that the motion dynamics are predominantly controlled by intensity and temporal pattern of rainfall. A new empirical threefold rainfall threshold was therefore proposed to forecast the dates for the moderate/major movements. This threshold relies upon antecedent water‐year and previous 3‐day and daily precipitation and was able to represent observed movement periods well. Adaptation of our threshold methodology could prove useful for other large, deep landslides for which temporal forecasting has long been generally intractable. The averaged characteristic hydraulic conductivity and diffusivity were estimated as 6.6 × 10 −6 m/s and 6.6 × 10 −4 m 2 /s, respectively, based on the time lags between rainfall pulses and slide accelerations. Hydrologic modeling using these parameters helps to explain the ability of the new rainfall threshold.

Gender Prediction for a Multiethnic Population via Deep Learning Across Different Retinal Fundus Photograph Fields: Retrospective Cross-sectional Study (Preprint) (2020)

<sec> <title>BACKGROUND</title> Deep learning algorithms have been built for the detection of systemic and eye diseases based on fundus photographs. The retina possesses features that can be affected by gender differences, and the extent to which these features are captured via photography differs depending on the retinal image field. </sec> <sec> <title>OBJECTIVE</title> We aimed to compare deep learning algorithms’ performance in predicting gender based on different fields of fundus photographs (optic disc–centered, macula-centered, and peripheral fields). </sec> <sec> <title>METHODS</title> This retrospective cross-sectional study included 172,170 fundus photographs of 9956 adults aged ≥40 years from the Singapore Epidemiology of Eye Diseases Study. Optic disc–centered, macula-centered, and peripheral field fundus images were included in this study as input data for a deep learning model for gender prediction. Performance was estimated at the individual level and image level. Receiver operating characteristic curves for binary classification were calculated. </sec> <sec> <title>RESULTS</title> The deep learning algorithms predicted gender with an area under the receiver operating characteristic curve (AUC) of 0.94 at the individual level and an AUC of 0.87 at the image level. Across the three image field types, the best performance was seen when using optic disc–centered field images (younger subgroups: AUC=0.91; older subgroups: AUC=0.86), and algorithms that used peripheral field images had the lowest performance (younger subgroups: AUC=0.85; older subgroups: AUC=0.76). Across the three ethnic subgroups, algorithm performance was lowest in the Indian subgroup (AUC=0.88) compared to that in the Malay (AUC=0.91) and Chinese (AUC=0.91) subgroups when the algorithms were tested on optic disc–centered images. Algorithms’ performance in gender prediction at the image level was better in younger subgroups (aged &amp;lt;65 years; AUC=0.89) than in older subgroups (aged ≥65 years; AUC=0.82). </sec> <sec> <title>CONCLUSIONS</title> We confirmed that gender among the Asian population can be predicted with fundus photographs by using deep learning, and our algorithms’ performance in terms of gender prediction differed according to the field of fundus photographs, age subgroups, and ethnic groups. Our work provides a further understanding of using deep learning models for the prediction of gender-related diseases. Further validation of our findings is still needed. </sec>
A 12A 50V half-bridge gate driver for enhancement-mode GaN HEMTs with digital dead-time correction (2015)

This paper presents a high-frequency half-bridge driver for enhancement-mode GaN-on-Si HEMTs with digital dead-time correction (DDTC) to optimize the dead-time. Due to the lateral HEMT structure, dead-time optimization is essential for synchronous driving. It helps reducing the reverse conduction loss to enhance the efficiency and reliability. The DDTC scheme achieves instant sensing with all-digital feedback control to adjust the dead-times dynamically according to load changes. The proposed half-bridge driver for GaN HEMTs is designed in 0.35μm HV CMOS technology. Simulation results show that the DDTC scheme is able to reduce the dead-times to within 2ns and the efficiency is improved by 4.9% compared to the fixed dead-time scheme in a 12V-1.2V conversion with a 12A load current.

Comparison of <i>Haemophilus influenzae</i> Seroprevalence in Serum Samples Collected from 0- to 5-Year-Old Japanese Children in 1980, 1995, 2010, and 2012 (2019)

Haemophilus influenzae type b (Hib) causes several invasive infections such as meningitis, septic arthritis, and pneumonia, especially in children below 5 years old. Despite the availability of Hib vaccines against Hib infection, seroepidemiological surveys of Hib infections have not yet been systematically conducted in Japan. We analyzed 1,338 serum samples, provided by the National Serum Reference Bank of the National Institute of Infectious Diseases (Tokyo, Japan), from 0- to 5-year-old children. Anti-polyribosylribitol phosphate (PRP) immunoglobulin G (IgG) antibody levels against Hib were determined using an anti-H. influenzae IgG enzyme immunoassay kit. In a total of 1,168 (87.3%) serum samples from children, anti-PRP IgG antibody levels were ≥ 0.15 μg/mL, providing natural immunity. Titers expected to provide long-term protection (≥ 1 μg/mL) were increased from 2.7% to 51.6% in children < 1 year old after the introduction of Hib vaccine (1980, 5.3%; 1995, 2.7%; 2010, 22%; 2012, 51.6%). Our data confirmed that the introduction of Hib vaccination in children below 5 years old increased the proportion of children having high anti-PRP IgG antibody levels, ensuring long-term protection against Hib.
Design and Characterization of a High-Power Laser-Induced Acoustic Desorption Probe Coupled with a Fourier Transform Ion Cyclotron Resonance Mass Spectrometer (2007)

We report here the construction and characterization of a high-power laser-induced acoustic desorption (LIAD) probe designed for Fourier transform ion cyclotron resonance mass spectrometers to facilitate analysis of nonvolatile, thermally labile compounds. This "next generation" LIAD probe offers significant improvements in sensitivity and desorption efficiency for analytes with larger molecular weights via the use of higher laser irradiances. Unlike the previous probes which utilized a power-limiting optical fiber to transmit the laser pulses through the probe, this probe employs a set of mirrors and a focusing lens. At the end of the probe, the energy from the laser pulses propagates through a thin metal foil as an acoustic wave, resulting in desorption of neutral molecules from the opposite side of the foil. Following desorption, the molecules can be ionized by electron impact or chemical ionization. Almost an order of magnitude greater power density (up to 5.0x10(9) W/cm2) is achievable on the backside of the foil with the high-power LIAD probe compared to the earlier LIAD probes (maximum power density approximately 9.0x10(8) W/cm2). The use of higher laser irradiances is demonstrated not to cause fragmentation of the analyte. The use of higher laser irradiances increases sensitivity since it results in the evaporation of a greater number of molecules per laser pulse. Measurement of the average velocities of LIAD-evaporated molecules demonstrates that higher laser irradiances do not correlate with higher velocities of the gaseous analyte molecules.

Neisseria gonorrhoeae co-infection exacerbates vaginal HIV shedding without affecting systemic viral loads in human CD34+ engrafted mice (2018)

HIV synergy with sexually transmitted co-infections is well-documented in the clinic. Co-infection with Neisseria gonorrhoeae in particular, increases genital HIV shedding and mucosal transmission. However, no animal model of co-infection currently exists to directly explore this relationship or to bridge the gap in understanding between clinical and in vitro studies of this interaction. This study aims to test the feasibility of using a humanized mouse model to overcome this barrier. Combining recent in vivo modelling advancements in both HIV and gonococcal research, we developed a co-infection model by engrafting immunodeficient NSG mice with human CD34+ hematopoietic stem cells to generate humanized mice that permit both systemic HIV infection and genital N. gonorrhoeae infection. Systemic plasma and vaginal lavage titres of HIV were measured in order to assess the impact of gonococcal challenge on viral plasma titres and genital shedding. Engrafted mice showed human CD45+ leukocyte repopulation in blood and mucosal tissues. Systemic HIV challenge resulted in 104-105 copies/mL of viral RNA in blood by week 4 post-infection, as well as vaginal shedding of virus. Subsequent gonococcal challenge resulted in unchanged plasma HIV levels but higher viral shedding in the genital tract, which reflects published clinical observations. Thus, human CD34+ stem cell-transplanted NSG mice represent an experimentally tractable animal model in which to study HIV shedding during gonococcal co-infection, allowing dissection of molecular and immunological interactions between these pathogens, and providing a platform to assess future therapeutics aimed at reducing HIV transmission.
A Broadband Microwave Noise Generator Using Zener Diodes and a New Technique for Generating White Noise (2018)

A microwave noise generator using Zener diodes as the source of noise has been designed and built. It generates almost constant noise power about 20 dB above the noise floor up to 3.2 GHz. The noise generator circuit employs two independent current sources and two identical Zener diodes to generate independent noise powers optimized for lower frequencies (<;1.4 GHz) and higher frequencies (>1.4 GHz). When the noise powers are combined on the same resistive load, the result is an almost flat noise power over the measured spectrum.
Evidence for a HeLa nuclear protein that binds specifically to the single-stranded d(CCCTAA)n telomeric motif (1996)

In recent years several telomere binding proteins from eukaryotic organisms have been identified that are able to recognise specifically the duplex telomeric DNA repeat or the G-rich 3'-ending single strand. In this paper we present experimental evidence that HeLa nuclear extracts contain a protein that binds with high specificity to the single-stranded complementary d(CCCTAA)n repeat. Electrophoretic mobility shift assays show that the oligonucleotide d(CCCTAACCCTAACCCTAACCCT) forms a stable complex with this protein in the presence of up to 1000-fold excesses of single-stranded DNA and RNA competitors, but is prevented from doing so in the presence of its complementary strand. SDS-PAGE experiments after UV cross-linking of the complex provide an estimate of 50 kDa for the molecular weight of this protein.

Practical importance: Implementation and development of domestic intelligence systems, designed to organize the management of public route transport operation, is of great relevance for economic development of the country.
[Evaluation of the QBC-Autoread System in hematological screening in a hospital laboratory]. (1994)

The QBC Autoread System is based on fully automatic, electro-optical linear measurements of the discrete layers of packed blood cells in a microhematocrite tube. The layering results from differing cell densities during high-speed centrifugation. The determination of hemoglobin, hematocrit, leucocytes, platelets and of the percentual share of granulocytes and lymphocytes/monocytes with the QBC Autoread System was evaluated concerning reliability and precision in comparison with the conventional analytical methods. We used a Coulter Counter System and the manual differentiation of the stained blood smears as reference methods. The evaluation of the first 400 blood samples showed a close correlation for all hematological parameters examined, but no significant deviation relative to the reference methods. Only 83 of totally 1000 (8.3%) examined venous blood samples could not be evaluated completely by the QBC Autoread System. For the analysis of very pathological cell populations, especially of hematological oncological diseases, the QBC System is not qualified. The extreme portability, the quick practicability and the good accordance with the conventional analytical methods make the QBC Autoread System a qualified screening method for practice and emergency laboratories.
Keynote Speakers (2007)

RFID, Radio Frequency Identification, is an emerging technology in the world of automatic identification. It uses RF signal for gathering information of tags, which can be attached or embedded to goods such as consumer electronics, items in supermarkets, automobile's parts. It may make our life more comfortable and more ubiquitous, but it may make us, on the other hand, more nervous. This is because that there are some privacy problems in RFID system. More comfortable automatic identifications would lead to more disclosure of our private life. This reason rushed many researches results related to security and privacy in RFID system. However, we cannot choose anything among them for applying to the current RFID system. Most of them require either of high-cost hardware specification or giving up potential convenience of consumers. In this paper, we propose a simple privacy protection scheme that can be used for the current existing RFID system such as ISO 18000-6 type C. We modify this standard tag identification protocol slightly and introduce a light-weight proxy device for privacy enhancing.

Metal ion – biomolecule interactions. X. Synthesis, spectroscopic and magnetic resonance investigations of methylmercury(II) complexes of the sulfur modified nucleosides 6- mercaptopurine riboside and 2-amino-6-mercaptopurine riboside (1986)

A number of methylmercurated complexes of 6-mercaptopurine riboside and 2-amino-6-mercaptopurine riboside (6-MNucH 2 ) containing S-bound CH 3 Hg(II) in neutral and cationic complexes (as in [CH 3 Hg(6-MNucH)] and [CH 3 Hg(6-MNucH 2 )]NO 3 ), S- and N-bound CH 3 Hg(II) (as in [(CH 3 Hg) 2 (6-MNucH)]NO 3 ), and S-, N-, C-bound CH 3 Hg(II) (as in [(CH 3 Hg) 3 (6-MNuc)]NO 3 ) have been prepared in aqueous solution at appropriate pH and mole ratios of the constituents. The complexes were characterized by means of 1 H and 13 C nmr and ir spectroscopy and elemental analysis. Formation of C-bound methylmercurated species extends our previous results obtained with xanthosine, inosine, and imidazole derivatives, and substantiates our proposal that activation through electrophilic coordination at N(7) is a requirement for C(8)—H abstraction. 2 J( 1 H– 199 Hg) coupling constants, measured in (CD 3 ) 2 SO for a number of CH 3 Hg(II) complexes of N-, S-, and C-donor heterocyclic ligands, including the 6-mercaptopurine riboside of the present study, correlate well with the 1 J( 13 C– 199 Hg) coupling constants, according to 1 J = 8.460 2 J − 155.6. The significance of this correlation in terms of the strength of the Hg–ligand bond is considered. The results could provide insight into the apparent selectivity of binding of CH 3 Hg(II) by bio-ligands, as well as in the design of chemotherapeutic agents for the treatment of methylmercury poisoning.
A Multilevel Confirmatory Factor Analysis of the Practice Environment Scale (2010)

Background: Practice Environment Scale (PES) data are collected from RNs in nursing units in hospitals that are members of the National Database of Nursing Quality Indicators (NDNQI). Patient and RN information are collected to aid in quality improvement and research at the nursing unit level. The data were collected from the individual RN, but items are worded so that analyses can be conducted at the individual, unit, or hospital level. There is a need to examine the validity of the PES at both the individual and the unit level. Objective: To describe multilevel confirmatory factor analysis via a case study for investigating the validity of the PES, a measure of the nursing practice environment. Approach: The PES was administered to 72,889 RNs from 4,783 nursing units (16 unit types; e.g., critical care and obstetric) in 2007. The PES has 31 items in five different domains. A multilevel confirmatory factor analytic model was fit with a structure on the basis of the five domains. From this model, an estimate was sought between unit loadings and within unit loadings to investigate factorial, convergent, and discriminant validity at both the unit and the RN levels. To investigate criterion-related validity, the five PES domains were correlated with the seven job enjoyment items adapted from the National Database of Nursing Quality Indicators at the unit and RN levels (also using a multilevel model). Results: The multilevel factor analysis provides evidence of factorial, convergent, discriminant, and criterion-related validity at both the unit and the RN levels. Discussion: The PES is a valid instrument for use in quality improvement and research both at the unit and individual RN levels.

Monitoring of immunologic status of patients receiving BCG therapy for malignant disease (1976)

BCG immunotherapy in a standard regime was administered by scarification to 26 selected patients with controlled malignant disease, 14 with lung cancer and 12 with melanoma. All were followed for 12 months after the first BCG administration or until death. During the first 3 months, when BCG was given weekly, immune reactivity as determined by skin tests and in vitro lymphocyte responses to phytohemagglutinin and recall antigens was enhanced in all patients except those in whom recurrence or extension of malignancy subsequently occurred. Patients who had received prior radiation therapy for lung cancer also did not manifest significant immunoenhancement. During the following 9 months when BCG was administered at increasing intervals, immune responses were maintained except in those patients who experienced recurrence of malignancy, and those who discontinued BCG therapy. The response to PHA was predictive of a favorable clinical course during the following 9 months, and was significantly impaired in advance of the clinical recurrence of malignancy. Tests of cell-mediated immunity, particularly the in vitro response to HA, are valuable in assessing the efficacy of BCG immunotherapy, prognosticating clinical progress, and predicting the recurrence of malignancy.
