High transmission and low color cross-talk plasmonic color filters using triangular-lattice hole arrays in aluminum films (2010)

Three primary color (red, green and blue) filters consisting of subwavelength triangular-lattice hole arrays in an aluminum film on glass were simulated and fabricated. A silicon dioxide cap layer, deposited on the patterned aluminum film, was found to almost double the transmission efficiency for all the filters. The measured peak transmittance for each color filter was above 30%, exhibiting a wavelength spectrum with a full-width at half-maximum of approximately 100 nm. Simulation results of various structures with different cap layers revealed the enhanced coupling between surface plasmon resonances at both sides of the metal film in a symmetrical configuration. It was found that gratings with as few as three periods were sufficient to demonstrate filtering. The effect of metal thickness and hole size was investigated in detail.
The Degree of Pigmentation Modulates the Radiosensitivity of Human Melanoma Cells (2000)

The relationship between cell pigmentation and radiosensitivity was investigated in two selected human melanoma cell lines with different melanin content (mixed type: eumelanin and pheomelanin, and pheomelanotic phenotypes). The same study was also done after stimulation of melanogenesis (1) by addition of the melanin precursor l-tyrosine to each of the cell lines separately and (2) by irradiation alone with doses ranging from 0 to 10 Gy. We found that a decrease in cell radiosensitivity was correlated with the type of melanin, with a clear involvement of eumelanin rather than pheomelanin. Increasing the intracellular content of both melanins promoted the growth of irradiated cells. Moreover, at a dose of 10 Gy, both tyrosinase activity and melanin cell content were significantly increased in the absence of any other melanogenesis promoter. Our data suggest that the amount of intracellular melanin is inversely related to the radiosensitivity of melanoma cells and may explain at least in part the controversial responses to ionizing radiations reported for melanoma.
Technology of direct conversion for mirror reactor end-loss plasma (1980)

Design concepts are presented for plasma direct convertors (PDC) intended primarily for use on the end-loss plasma from tandem-mirror reactors. Recent experimental results confirm most of these design concepts. Both a one-stage and a two-stage PDC were tested in reactor-like conditions using a 100-kV, 6-kW ion beam. In a separate test on the end of the TMX machine, a single stage PDC recovered 79 W for a net efficiency of 50%. Tandem mirror devices are well suited to PDC. The high minimum energy of the end-loss ions, the magnetic expansion outside the mirrors, and the vacuum conditions in the end tanks required by the confined plasma, all preexist. The inclusion of a PDC is therefore a rather small addition. These facts and the scale parameters for a PDC are discussed.

ANOMALOUS INFRARED PROPERTIES OF THE OXYGEN DEFICIENT CUPRATE La8-xSrxCu8O20 (2000)

We present the first infrared conductivity spectra on single crystals of oxygen deficient cuprate La 8- x Sr x Cu 8 O 20 . The infrared conductivity for a sample with x = 2.24 behaves as a function of temperature according to a conventional Drude model. On the other hand, the low energy excitations for a sample with x =1.56 are itinerant polarons. Below T =100 K , polarons localize and this effect can be related to the anomalies present in the transport and magnetic properties around this temperature.
Linearity Measurement of 6G Receiver with One Transmission Frequency Extender Operating at 330 GHz (2021)

The future sixth-generation (6G) is envisioned to support data rates up to 1 Tbps. The operational frequencies of the 6G system will be expanded towards the sub-mmW and THz regions. The 6G systems will utilize directive beams, as well, to compensate increased signal attenuation between link ends. The linearity of a receiver (Rx) is one of the most significant parameters for any radio system. Traditional Rx linearity measurement relies on a two-tone measurement technique, which requires two dedicated RF signals and combining them to the test signal. The generation of two independent RF signals at a 300 GHz frequency band leads to a costly and bulky solution. This paper proposes a linearity measurement method for 6G Rx, which uses only one continuous wave transmission frequency extender. A method is proposed where the RF input signal of frequency extender is narrowband amplitude modulated (AM), generating side tones around continuous wave carrier. The carrier frequency and first side tones are used as test signals, and the linearity test is like a traditional two-tone test with unequal signals. It is shown that the carrier level can be modified by back-offing the RF input power in the frequency extender input. By varying the AM modulation index, the side tones' levels can be varied, enabling the sweep of the tone input power to perform Rx linearity measurements.
Survey of Annual Fluctuations in Total Geomagnetic Intensity Observations (2010)

Annual fluctuations in total magnetic intensity are observed at the continuous total geomagnetic intensity station (79F) at the Memambetsu branch. To identify the causes of this fluctuation, we measured outdoor air temperature and underground temperatures (at depths of 0.1, 0.5, and 1 m) near 79F in order to clarify their relationship with the fluctuations in total geomagnetic intensity. The results of this survey revealed that the annual fluctuations have a high correlation with the underground temperatures near the ground surface. We also conducted a magnetic survey in an area of the Memambetsu branch including 79F, and we found that the magnetic gradient near 79F was considerably greater in the east-west direction (10 nT/m) than that in the north-south direction. We therefore concluded that the annual fluctuations at 79F are caused by local variations in the magnetic field around the station that result from temperature changes.
Stress Corrosion Cracking of Stainless Steel Components in Steam Service (2001)

Abstract The paper discusses stress corrosion cracking (SCC) of stainless steel components due to the ingress of caustic into steam systems. Also reviewed are case histories in which laboratory investigations assisted in identifying the root causes involved and proper corrective actions to resolve this problem.
Characterization of AlGaN HEMT structures (2007)

During the last decade, AlGaN High Electron Mobility Transistors (HEMTs) have been intensively studied because their fundamental electrical properties make them attractive for highpower microwave device applications. Despite much progress, AlGaN HEMTs are far from fully understood and judged by the number of published papers the understanding of advanced structures is even poorer. This work is an exploration of the electrical and structural properties of advanced HEMT structure containing AlN exclusionlayer and double heterojunctions. These small modifications had great impact on the electrical properties. In this work, AlGaN HEMT structures grown on SiC substrates by a hot-wall MOCVD have been characterized for their properties using optical microscopy, scanning electron microscopy, transmission electron microscopy, capacitance/voltage, eddy-current resistivity, and by homebuilt epi-thickness mapping equipment. A high electron mobility of 1700 [cm2/Vs] was achieved in an AlN exclusion-layer HEMT. A similar electron mobility of 1650 [cm2/Vs] was achieved in a combination of a double heterojunction and exclusion-layer structure. The samples had approximately the same electron mobility but with a great difference: the exclusion-layer version gave a sheet carrier density of 1.58*1013 [electrons/cm2] while the combination of double heterojunction and exclusion-layer gave 1.07*1013 [electrons/cm2]. A second 2DEG was observed in most structures, but not all, but was not stable with time. The structures we grew during this work were also simulated using a one-dimensional Poisson-Schrödinger solver and the simulated electron densities were in fairly good agreement with the experimentally obtained. III-nitride materials, the CVD concept, and the onedimensional solver are shortly explained.
Pressure Enhancement of the Net Acoustic Gain in Piezoelectric Semiconductors (1970)

Hydrostatic pressures of up to 16 kbar are shown to increase the net acoustoelectric gain in semiconducting CdS and CdSe. Decreasing conductivity with pressure in CdS is attributed to a decrease in both mobility and carrier concentration whereas no significant changes were observed in CdSe. The frequency of maximum gain, as calculated from linear theory, decreases with pressure in CdS.

Support Effects of Containing Catalysts on Methanol Dehydrogenation (2002)

CuO/ZnO, CuO/SiO,sub>2, and CuO/ZrO2 catalysts were prepared for investigating the support effects on methanol dehydrogenation. It was found that the conversion of methanol was proportional to the copper surface area on Cu/ZnO cat alysts and was independent on that on Cu/ZrO2 and Cu/SiO2. The highest copper surface area was obtained with the Cu/ZrO2 (9/1). The unusual deactivation of the Cu/ZnO, which showed the highest selectivity among the catalysts tested, was observed. Pulse reaction with methanol indicated that the lattice oxygen in ZnO could be removed by forming CO2 in the catalytic reaction, supporting that the ZnO reduction was responsible for the severe deactivation of the Cu/ZnO.
Interoperability of multiple autonomous databases (1990)

Database systems were a solution to the problem of shared access to heterogeneous files created by multiple autonomous applications in a centralized environment. To make data usage easier, the files were replaced by a globally integrated database. To a large extent, the idea was successful, and many databases are now accessible through local and long-haul networks. Unavoidably, users now need shared access to multiple autonomous databases. The question is what the corresponding methodology should be. Should one reapply the database approach to create globally integrated distributed database systems or should a new approach be introduced? We argue for a new approach to solving such data management system problems, called multidatabase or federated systems. These systems make databases interoperable, that is, usable without a globally integrated schema. They preserve the autonomy of each database yet support shared access. Systems of this type will be of major importance in the future. This paper first discusses why this is the case. Then, it presents methodologies for their design. It further shows that major commerical relational database systems are evolving toward multidatabase systems. The paper discusses their capabilities and limitations, presents and discusses a set of prototypes, and, finally, presents some current research issues.
Long‐term follow‐up of chemoimmunotherapy with rituximab, oxaliplatin, cytosine arabinoside, dexamethasone (ROAD) in patients with relapsed CD20+ B–cell non‐Hodgkin lymphoma: Results of a study of the Mayo Clinic Cancer Center Research Consortium (MCCRC) MC0485 now known as academic and community cancer research united (ACCRU) (2017)

Patients with relapsed aggressive non-Hodgkin lymphoma (NHL) are often treated with platinum-based chemoimmunotherapy regimens in preparation for autologous stem cell transplant. We sought to reduce toxicity and maintain efficacy by using oxaliplatin with rituximab, cytarabine and dexamethasone (ROAD) in a phase II clinical trial in patients who had relapsed after one prior regimen. ROAD was delivered q21 days and consisted of rituximab 375 mg/m<sup>2</sup> IV weekly x 4 doses (cycle 1 only); dexamethasone 40 mg PO/IV d2 - 5; oxaliplatin 130 mg/m<sup>2</sup> IV day 2; cytarabine 2000 mg/m<sup>2</sup> IV × two doses on days 2 to 3; and pegfilgrastim 6 mg SC on day 4. Forty-five eligible patients were accrued between 2006 and 2008. Patient characteristics were a median age of 69 years; 96% had received prior rituximab; 53% were within one year of diagnosis. The median number of cycles received was 2 (range, 1-6). Forty-four % received ROAD as an outpatient. The overall response rate was 71% with 27% (12/45) CR and 44% (20/45) PR. Forty-four % (20/45) of all patients and 69% (18/26) of patients whom responded after 2 cycles proceeded to transplant. Median overall survival was 26 mos (95% CI: 7.3 mos-not reached) and median progression-free survival was 11 mos (95% CI: 6-104 mos). There was no grade 3/4 nephrotoxicity; the rate of grade 3/4 neuropathy was 4%. Forty-two percent of all patients and 69% of patients transplanted remain alive at 5 years. ROAD represents an acceptable salvage therapeutic option for patients with relapsed aggressive NHL.
Clinical characteristics of hemophagocytic lymphohistiocytosis following Kawasaki disease: differentiation from recurrent Kawasaki disease (2013)

A diagnosis of HLH-KD should be considered when symptoms similar to recurrent KD develop within 1 month of the first episode of KD. Our findings will help physicians differentiate between HLH and the recurrent form of KD.
Two new ascomycetes from rainforest litter in Costa Rica (2006)

Two new ascomycetes, Boerlagiomyces costaricensis (Pleosporales) and Scopinella musciformis (Sordariales sensu lato), from litter samples collected in rainforests of Costa Rica, are described and illustrated. Boerlagiomyces costaricensis has globose, ostiolate ascomata covered by numerous setae-like hairs; cylindrical, fissitunicate asci without apical structures; and large, fusiform, muriform, hyaline to pale brown ascospores. Scopinella musciformis is characterized by ostiolate ascomata with a few compact clusters of hypha-like hairs distributed on the peridial surface and a long neck; ovate to ellipsoidal unitunicate asci; and small quadrangular ascospores with diagonal germ slits.
[Adult's outcome of attention deficit hyperactivity disorder and its predictive factors (review)]. (2007)

The prognosis of attention deficit hyperactivity disorder (ADHD) is poor, and approximately two third patients still have obvious symptoms when they grow up into adults, thus interfering with their social functions including work, study, family and interpersonal relation etc, and even causing the mental disorders and/or antisocial personality disorder. The predictive factors of adult outcome of ADHD include genetic, environmental and clinical factors. This review deals with the adult outcome and its predictive factors,and explores the severest harmfulness against individual, family and society brought by ADHD and its underlying mechanisms so as to facilitate the clinical intervention and research.
Boundary integral equation approach to multi-mode Y-Matrix characterization of multi-ridged sections in circular waveguide (2002)

Aiming at an accurate and effective CAD procedure for circular waveguide (CW) dual-mode filters without tuning screws, the boundary integral equation method (BIEM) is applied to TM/TE mode analysis of Multi-Ridge circular waveguide (MRCW) and evaluation of CW-MRCW mode coupling coefficients to obtain the Multi-Mode network (Y-Matrix) representation (MMNR) of CW-MRCW transitions. A novel multiple eigenvalue search algorithm assures completeness of the modal spectrum up to large mode indices (>100) in the presence of accidental degeneracies and clusters of eigenvalues.

Unwarping confocal microscopy images of bee brains by nonrigid registration to a magnetic resonance microscopy image (2005)

Confocal microscopy (CM) is a powerful image acquisition technique that is well established in many biological applications. It provides 3-D acquisition with high spatial resolution and can acquire several different channels of complementary image information. Due to the specimen extraction and preparation process, however, the shapes of imaged objects may differ considerably from their in vivo appearance. Magnetic resonance microscopy (MRM) is an evolving variant of magnetic resonance imaging, which achieves microscopic resolutions using a high magnetic field and strong magnetic gradients. Compared to CM imaging, MRM allows for in situ imaging and is virtually free of geometrical distortions. We propose to combine the advantages of both methods by unwarping CM images using a MRM reference image. Our method incorporates a sequence of image processing operators applied to the MRM image, followed by a two-stage intensity-based registration to compute a nonrigid coordinate transformation between the CM images and the MRM image. We present results obtained using CM images from the brains of 20 honey bees and a MRM image of an in situ bee brain.
Small-signal analysis of closed-loop PWM boost converter in CCM with complex impedance load (2016)

The following closed-loop transfer functions of the boost converter operating in continuous-conduction mode (CCM) supplying a complex impedance load are derived and analyzed: input-to-output voltage M <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">vcl</sub> and reference-to-output T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">cl</sub> . The load of the boost dc-dc converter is composed of a series-connected resistance and inductance. The dynamic characteristics of the closed-loop boost converter with a third-order double-lead integral compensator are evaluated for different load inductances. The theoretically predicted results are validated through switching-circuit simulations using a suitable converter design example.

Calculating the Phonon Modes of Graphene Using the 4th Nearest Neighbor Force Constant Method (2008)

Graphite has always been a very important material both industrially and academically due to its physical structure. But ever since the isolation of Graphene (a single sheet of Graphite) a few years ago, it’s been one of the most widely studied molecular systems for its potential applications in nano-electronics and other break-through areas. Some of the desirable traits of Graphene are its high thermal and electronic mobility, and its low noise properties. This paper outlines a standard method for calculating phonon dispersion curves in Graphene by making use of force constant measurements. This information is usually obtained from approximations of inter-atomic potentials, which involve derivatives of simplified potential approximations between every atom in Graphene to get the force constant tensors. In this paper, the measured values for the force constants are used in a mathematically rigorous way to calculate the Graphene phonon dispersion curves.
Meta-Analysis of PD-L1 Expression As a Predictor of Survival After Checkpoint Blockade (2020)

The practice of dichotomizing the range of PD-L1 expression scores is inadequate for patient stratification. Meta-analytic estimates of the distribution of PD-L1 scores and subgroup-specific treatment effects can improve the designs of future trials of ICIs.
Modulation of lymphocyte subsets in Peyer's patches of mice treated with monoclonal antibody against helper T-cells. (1988)

Treatment of mice with anti-L3T4, a monoclonal antibody directed against helper T-cells, impairs clearance of intestinal Giardia muris infection. The present study examined the effect of anti-L3T4 treatment on mouse Peyer's patch cytoarchitecture and on the distribution of T-cell subsets within microenvironments of the follicle. Female BALB/c mice, aged 8 weeks, were given 4-7 weekly injections of either anti-L3T4 (1 mg/wk) or PBS (control group), and Peyer's patches were examined by immunohistochemistry or flow cytometry. In anti-L3T4-treated mice, Peyer's patch follicles (B-cell areas) were about two thirds the size of follicles in controls, and virtually all the size difference occurred in germinal centers. Peyer's patches were depleted of L3T4+ cells, yet the proportion of Thy-1.2+ (all T) cells was not decreased correspondingly, and the distribution of Thy-1.2+ cells in the patches was similar to that in control mice. In anti-L3T4-treated mice, Thy-1.2+ cells consisted of (a) Ly-2+ (cytotoxic/suppressor T) cells, and (b) a population of Thy-1.2+ cells that were neither L3T4+ nor Ly-2+. After treatment, Ly-2+ cells accounted for most of the T-cells in interfollicular areas and were also scattered in follicles, in germinal centers, and below the dome epithelium--in areas where L3T4+ cells predominated in control mice. Thy-1.2+ cells that were L3T4- and Ly-2- were mainly localized below the dome epithelium. These shifts indicate complex interrelationships among different lymphocyte subsets in Peyer's patches.
Crystallization Behavior of Amorphous Silicon Carbonitride Ceramics Derived from Organometallic Precursors (2001)

The crystallization behavior of organometallic‐precursor‐derived amorphous Si‐C‐N ceramics was investigated under N 2 atmosphere using X‐ray diffractometry (XRD), transmission electron microscopy (TEM), and solid‐state 29 Si nuclear magnetic resonance (NMR) spectroscopy. Amorphous Si‐C‐N ceramics with a C/Si atomic ratio in the range of 0.34–1.13 were prepared using polycarbosilane‐polysilazane blends, single‐source polysilazanes, and single‐source polysilylcarbodiimides. The XRD study indicated that the crystallization temperature of Si 3 N 4 increased consistently with the C/Si atomic ratio and reached 1500°C at C/Si atomic ratios ranging from 0.53 to 1.13. This temperature was 300°C higher than that of the carbon‐free amorphous Si‐N material. In contrast, the SiC crystallization temperature showed no clear relation with the C/Si atomic ratio. The TEM and NMR analyses revealed that the crystallization of amorphous Si‐C‐N was governed by carbon content, chemical homogeneity, and molecular structure of the amorphous Si‐C‐N network.
