All-selective MOVPE-grown 1.3-μm strained multi-quantum-well buried-heterostructure laser diodes (1999)

Strained InGaAsP multi-quantum-well (MQW) double-channel planar-buried-hetero (DC-PBH) laser diodes (LDs) were fabricated by selective metalorganic-vapor-phase epitaxy (MOVPE). In the laser fabrication process, both the strained MQW active layer and current blocking structure were directly formed by selective MOVPE without any semiconductor etching process. The LDs are called all-selective MOVPE-grown BH LDs. The laser fabrication process can achieve both a precisely controlled gain waveguide structure and an excellent current blocking configuration, realizing the optimized DC-PBH structure. These aspects are essential to the high-performance and low-cost LD, which is strongly demanded for optical access network systems or fiber-to-the-home networks. This paper will show the excellent high-temperature characteristics for 1.3-/spl mu/m Fabry-Perot LDs which have a record threshold current of 18 mA with a low-operation current of 56 mA for 10 mW, and 74 mA for 15 mW at 100/spl deg/C with extremely high uniformity. Furthermore, reliable long-term operation at high temperature (85/spl deg/C) and high-output power of 15 mW has been demonstrated for the first time.
Strong and Specific Peroxidase Activity with an Antibody L Chain—Porphyrin Fe(III) Complex (1995)

We attempt to generate monoclonal antibodies as host proteins for the functional molecular porphyrin, and thus engineer a new type of catalytic antibody. TCPP (meso-tetrakis (4-carboxyphenyl) porphyin) was chemically synthesized and Balb/c mice were immunized using TCPP as a hapten. Two hybridoma cells (03-1, 13-1), which produce monoclonal antibody against TCPP, were obtained. One of the monoclonal antibodies, Mab 03-1, exhibited enhanced peroxidase activity when TCPP Fe(III) was incorporated. Genes for both H and L chains of monoclonal antibodies were cloned, sequenced and overexpressed using E. coli as a host. ELISA and fluorescence quenching method show that the antibody L chains from both Mab 03-1 and Mab 13-1 have specific strong interaction with TCPP. Furthermore, a TCPP Fe(III) complex with the L chain from Mab 13-1 exhibits much higher peroxidase activity than TCPP Fe(III) alone. The enzyme activity was detectable with pyrogallol and ABTS(2,2-azinobis 3-ethylbenzthiazolin-6-sulfonic acid) but not with catechol. This result provides a new concept of catalytic antibody using monoclonal antibody or antibody fragment as a host carrier protein for a functional molecule.

Fifth order low-pass transitional Gm-C filter with relaxation oscillator frequency tuning circuit (2004)

The design and implementation of gm-C filter with on-chip automatic tuning circuit is described. Transitional Bessel-Chebyshev filter is implemented to compromise between high attenuation and low group-delay variation. The circuit is fabricated with 0.18 /spl mu/m CMOS process with 6-metal single poly. The filter operates at a cutoff frequency of 10 MHz with a single 1.3 V supply voltage. The measurement results shows an attenuation of 70 dB at stop-band can be achieved, while keeping a low group-delay variation of less than 7 nSec up-to 1.5 times of cutoff frequency. The cutoff frequency can be linearly tuned from 4 MHz to 10 MHz through the tuning loop. By employing relaxation oscillator, accurate and robust frequency tuning scheme is implemented. Measured with sufficient samples, the frequency tuning circuit shows an cutoff frequency tuning error of less than 7.0% over wide range of supply voltages (1.3 V to 2.1 V) and operating temperatures (-40/spl deg/C to +85/spl deg/C) in the whole tuning range.
Composite Steel Stud Blast Panel Design and Experimental Testing (2011)

Based on Federal Aviation Authority (FAA) requirements, project specific blast loads are determined for the design of a new airport traffic control tower. These blast loads must be resisted by exterior wall panels on the control tower, protecting building occupants from intentional explosives attack scenarios. Such blast resistant walls are typically constructed of thick reinforced concrete panels or composite steel plate and rolled sections, as conventional building cladding systems have relatively low blast resistance. While these more robust design approaches are valid, the additional cladding mass they represent will significantly increase the base shear and overturning demand in seismic zones. This paper investigates the use of a light structural system comprised of a steel stud wall assembly partially embedded in a thin layer of concrete to obtain composite action. Fiber reinforced polymer (FRP) composites are also included to increase the blast resistance and aid in keeping the panel weight to a minimum. Two full-scale composite steel stud walls are designed, constructed, and tested dynamically in the BakerRisk shock tube. The stud walls consist of back-to-back 150 mm deep, 14 gauge (1.8 mm thick), cold-formed steel studs spaced at 610 mm on center. Both specimens have a 50 mm thick normal weight concrete layer, reinforced with welded wire mesh that is welded to the stud compression flanges to achieve composite action. Two layers of Tyfo® SEH-51A fiber reinforced composites are used on the tension flange of the steel studs. A single layer of Tyfo® SEH-51A composites is used on the tension face of the concrete layer between the studs for one of the specimens. Web stiffeners are used at the bearing support to prevent premature web crippling shear failure of the specimens. The stud walls are analyzed using single-degree-of-freedom (SDOF) models. A non-linear moment-curvature relationship, accounting for actual material constitutive properties, is used for determining the resistance function of the walls. Blast pressure and impulse data from the shock tube tests is used to compare analytical predictions to the measured displacement-time response. Analytical predictions of panel response for both tests are within ten percent of the observed response based on displacement.
Variations of Acoustic and Diffuse Mismatch Models in Predicting Thermal-Boundary Resistance (2000)

Solid-solid thermal-boundary resistance plays an important role in determining heat flow, in both cryogenic and room-temperature applications. The acoustic mismatch model (AMM) and the diffuse mismatch model (DMM) have traditionally been used to predict the thermal boundary resistance R b across the interface of two adjoining materials at temperatures well below the Debye temperatures of the materials in question. Both the AMM and DMM use the Debye density of states (DOS) in both contacting solids. Here, the use of a measured DOS is made in conjunction with the DMM. This shows an improvement in the prediction of R b relative to that based on the Debye DOS. Another approach considered is to predict R b from measured specific heat per unit volume C data. The measured C automatically includes the effect of temperature on the DOS. This leads to a marginal improvement in R b above that predicted when using the measured DOS. The AMM describes the thermal transport at a solid-solid interface below a few Kelvin quite accurately
Assessing the Groundwater Quality of Rohingya Refugee Camp Cox Bazar Bangladesh (2022)

Groundwater is the singular source of drinking water in Rohingya Refugee Camps, Cox Bazar Bangladesh. A study was conducted to assess the quality of the groundwater and its suitability as potable water. Samples collected from ten water points that are hand pumps connected to borehole wells locally called tube wells of Rohingya Camp16 were collected for analysis of water quality parameters. The water quality parameters that were measured were: pH, turbidity, total hardness, arsenic, manganese, iron, and total coliform. The results indicate that the water is moderately hard with pH values within regulatory limits. Some of the water samples exceed the limit for total iron based on the Government of Bangladesh regulatory standards. The water samples were arsenic free which is a relief for many localities in Bangladesh suffer from the purge of arsenic contaminated groundwater. Unfortunately, many of the water samples collected contains higher than accepted levels of manganese which can be an issue with prolonged consumption. Chronic exposure to manganese results in developmental problems in adolescents. The majority of the waters samples also showed the presence of total coliform and a sure indication that fecal contamination of the water wells is occurring. The water quality data points to a senior that calls for pragmatic water quality assurance and management measures for the sustainable wellbeing of the refugee communities in the refugee camps of Cox Bazar, Bangladesh. We will be putting forth evidence-based sustainable solutions to achieve a sustainable supply of safe drinking water to the Rohingya communities in the camps.
AI-driven imaging biomarkers for sensory cue integration during melanoma screening (Conference Presentation) (2020)

Early diagnosis of melanomas is the most effective means of improving melanoma prognosis. We can arm the non-expert screeners with artificial intelligence but most artificial intelligence methods are somewhat impractical in a clinical setting given the lack of transparency. To provide a quantitative and algorithmic approach to lesion diagnosis while maintaining transparency, and to supplement the clinician rather than replace them, our digital analysis provides visual features, or, “imaging biomarkers” that can both be used in machine learning and visualized too.

A 60μW 60nV/radicHz readout front-end for portable biopotential acquisition systems (2006)

A biopotential readout front-end can be configured to extract EEG, ECG, and EMG signals and draws 20μA from 3V. AC coupling of chopped amplifiers results in an input-referred noise of 60nV/radicHz and CMRR of 120dB at 1kHz. The immunity of the CMRR to electrode offset voltages is improved with an active input stage and 110dB CMRR is achieved at 100Hz with 50mV electrode offset
Normal abdominal enhancement patterns with dynamic gadolinium-enhanced MR imaging. (1991)

The objective of this study was to quantitatively and qualitatively determine contrast enhancement patterns of normal abdominal organs with dynamic gadolinium-enhanced magnetic resonance (MR) imaging. Dynamic gadolinium-enhanced, T1-weighted, spin-echo imaging was performed during a 23-second breath hold in 38 patients, with images acquired before, during, and at 1,2, and 5 minutes after bolus injection of gadopentetate dimeglumine. Enhancement patterns of normal liver, spleen, pancreas, adrenal gland, kidney, aorta, inferior vena cava, and fat were determined by visual evaluation and by performance of signal intensity measurements with an electronic cursor. Time-intensity curves demonstrated peak enhancement of all abdominal organs during or immediately after bolus injection of gadopentetate dimeglumine. MR enhancement patterns included visualization of renal cortical nephrogram and heterogeneous enhancement of the spleen during the bolus phase of contrast material administration. Peak enhancement of normal liver was 72%; spleen, 172%; pancreas, 82%; adrenal gland, 85%; and kidney, 291%. This study established reference data regarding abdominal organ enhancement that will be useful as dynamic gadolinium-enhanced MR imaging becomes clinically implemented.
Alpha/Beta Interferon and Gamma Interferon Synergize To Inhibit the Replication of Herpes Simplex Virus Type 1 (2002)

In vivo evidence suggests that T-cell-derived gamma interferon (IFN-gamma) can directly inhibit the replication of herpes simplex virus type 1 (HSV-1). However, IFN-gamma is a weak inhibitor of HSV-1 replication in vitro. We have found that IFN-gamma synergizes with the innate IFNs (IFN-alpha and -beta) to potently inhibit HSV-1 replication in vitro and in vivo. Treatment of Vero cells with either IFN-beta or IFN-gamma inhibits HSV-1 replication by <20-fold, whereas treatment with both IFN-beta and IFN-gamma inhibits HSV-1 replication by approximately 1,000-fold. Treatment with IFN-beta and IFN-gamma does not prevent HSV-1 entry into Vero cells, and the inhibitory effect can be overcome by increasing the multiplicity of HSV-1 infection. The capacity of IFN-beta and IFN-gamma to synergistically inhibit HSV-1 replication is not virus strain specific and has been observed in three different cell types. For two of the three virus strains tested, IFN-beta and IFN-gamma inhibit HSV-1 replication with a potency that approaches that achieved by a high dose of acyclovir. Pretreatment of mouse eyes with IFN-beta and IFN-gamma reduces HSV-1 replication to nearly undetectable levels, prevents the development of disease, and reduces the latent HSV-1 genome load per trigeminal ganglion by approximately 200-fold. Thus, simultaneous activation of IFN-alpha/beta receptors and IFN-gamma receptors appears to render cells highly resistant to the replication of HSV-1. Because IFN-alpha or IFN-beta is produced by most cells as an innate response to virus infection, the results imply that IFN-gamma secreted by T cells may provide a critical second signal that potently inhibits HSV-1 replication in vivo.
Complete Search Restart Strategies for Satisfiability (2001)

Search restarts is a well-known strategy for coping with hard real-world satisfiable (and often unsatisfiable) instances of Propositional Satisfiability (SAT), that is already being used by different state-of-the-art SAT solvers. Despite being extremely effective for solving real-world problem instances, the original search restart strategy yields an incomplete algorithm, that for unsatisfiable instances is unable to guarantee that unsatisfiability can be established. This paper describes different techniques for guaranteeing the completeness of SAT algorithms that implement search restart strategies, and proposes implementation optimizations to some of the proposed techniques. Experimental evidence indicates that the proposed techniques are effective for a wide range of real-world problem instances.
Research of Large Field of View Scan Mode for Industrial CT (2003)

For industrial computed tomography systems, generation II scan mode has a large field of view but time-consuming and generation III has a small field of view but fast. In order to realize the rapid ICT test of large objects, a scan mode based on generation III called large field of view scan was discussed and its reconstruction algorithm based on FBP was deduced. The validity of the algorithm was verified by the results of computer simulation and experiments. Analysis showed that the effective scan field of view could be improved by more than 90% compared with that of generation III.
¡Atención al tsunami!: La Red Nacional de Alerta de Tsunami (2015)

El miercoles 19 de noviembre, que no habia futbol europeo, se celebro en la sede del ICOG una tertulia del Geoforo que, bajo el titulo, iAtencion al tsunami!, analizo el desarrollo de la Red Nacional de Alerta de Tsunami instalada hace pocos meses por el Instituto Geografico Nacional (IGN). En la tertulia, presentada por Jose Luis Barrera, intervinieron Emilio Carreno, director de la Red Sismica Nacional, y Juan Vicente Cantavella, jefe de Servicio de Sismologia del IGN.
Carreno destaco en su intervencion la poca concienciacion que existe en Espana respecto al riesgo que representan los tsunamis (maremotos) y recordo que la mayor catastrofe natural registrada por nuestro pais fue precisamente un maremoto consecuencia del llamado terremoto de Lisboa del ano 1755. Aquel tsunami provoco mas de 1.200 muertos en la bahia de Cadiz, y los estudios paleosismicos realizados por los geologos en los ultimos anos han demostrado que esa zona ha padecido, al menos, cuatro grandes tsunamis a lo largo de la historia. En el Mediterraneo tambien se han registrado tsunamis de menor intensidad en 1790, 1804, 1954, 1980 y 2003 (hundio mas de 100 embarcaciones en Mallorca y Menorca), generalmente provocados por terremotos en la costa de Argelia. Globalmente, segun estos expertos, las regiones espanolas mas expuestas al riesgo de un tsunami son la costa del Atlantico, especialmente Huelva y la bahia de Cadiz, la costa del Mediterraneo y las islas Baleares, si bien la recurrencia de maremotos de gran intensidad es de entre 1.200 y 1.500 anos.
Tradeoffs Between Impurity Gettering, Bulk Degradation, and Surface Passivation of Boron-Rich Layers on Silicon Solar Cells (2012)

The suitability of using a boron-rich layer (BRL) formed during boron diffusion as a gettering layer for n-type silicon solar cells is investigated. We have studied the gettering effectiveness, generation of dislocations and associated bulk lifetime degradation, and the impact of the BRL on the saturation current density, for different thickness of BRL and postoxidation conditions. Our results show that a BRL deposited using BBr <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> -based furnaces is very effective at gettering interstitial Fe, removing more than 99.9% of Fe, but that the gettered Fe is released back into the wafer when the BRL is oxidized thermally. While we have detected no significant bulk degradation due to dislocations for the diffusion conditions used, there remains a tradeoff between the gettering effect and the recombination in the boron-doped region. Although the BRL can be oxidized chemically at low temperature using boiling nitric acid without losing the gettering effect, the lowest saturation current density is obtained by means of thermal oxidation, thanks partly to a lower boron surface concentration in thermally oxidized samples.

Prediction of restenosis based on hemodynamical markers in revascularized femoro-popliteal arteries during leg flexion (2019)

Endovascular therapy in patients suffering from peripheral arterial disease shows high rates of restenosis. The poor clinical outcomes are commonly explained by the demanding mechanical environment due to leg movements, but the mechanisms responsible for restenosis remain unknown. In this study, we hypothesized that restenosis following revascularization is associated with hemodynamical markers derived from blood flow during leg flexion. Therefore, we performed personalized computational fluid dynamics (CFD) analyses of 20 patients, who underwent routine endovascular femoro-popliteal interventions. The CFD analyses were conducted using 3D models of the arterial geometry in straight and flexed positions, which were reconstructed from 2D angiographic images. Based on restenosis rates reported at 6-month follow-up, logistic regression analyses were performed to predict restenosis from hemodynamical parameters. Results showed that severe arterial deformations, such as kinking, induced by leg flexion in stented arteries led to adverse hemodynamic conditions that may trigger restenosis. A logistic regression analysis based solely on hemodynamical markers had an accuracy of 75%, which showed that flow parameters are sufficient to predict restenosis (p = 0.031). However, better predictions were achieved by adding the treatment method in the model. This suggests that a more accurate image acquisition technique is required to capture the localized modifications of blood flow following intervention, especially around the stented artery. This approach, based on the immediate postoperative configuration of the artery, has the potential to identify patients at increased risk of restenosis. Based on this information, clinicians could take preventive measures and more closely follow these patients to avoid complications.
