Simulated and observed L-HH radar backscatter from tropical mangrove forests (1993)

Abstract We applied the Santa Barbara canopy backscatter model to model radar backscatter from mangrove forest stands in the Ganges delta of southern Bangladesh, and assessed the feasibility of delineating flooding boundaries within the stands. Modelled L-band (0-235 m wavelength) HH backscatter showed that canopy volume scattering dominated for stands under nonflooded ground surface. Double bounce trunk-ground term were enhanced by the presence of water under trees. For flooded mangrove forest, the trunk-ground term was dominant at small radar incidence angles; the trunk-ground term dominancy reduced as the incidence angle increased. Shuttle Imaging Radar (SIR-B) data and model results showed that for the mangrove forest, radar data with small incidence angles should be used to delineate the flooding boundaries.

A Thermodynamic Model for Wetting Free Energies from Contact Angles (2003)

A simple thermodynamic model for determining the wetting free energy of a small, sessile drop spreading on a solid surface has been derived by assuming that the process can be treated as adsorption. According to the model, free energies are expected to be small for large contact angles and increase exponentially as contact angles tend toward zero. Wetting free energies calculated using contact angles taken from the literature for various liquid−solid pairs agreed reasonably well with the bond strengths measured by other experimental techniques.
The Cytosolic Class II Chaperonin CCT Recognizes Delineated Hydrophobic Sequences in Its Target Proteins (1999)

The nonhomologous proteins actin and alpha- and beta-tubulin need the assistance of the cytosolic chaperonin containing TCP-1 (CCT) to reach their correct native state, and their folding requires a transient binary complex formation with CCT. We show that separate or combined deletion of three delineated hydrophobic sequences in actin disturbs the interaction with CCT. These sites are situated between residues 125-179, 244-285, and 340-375. Also, alpha- and beta-tubulin contain at least one recognition region, and intriguingly, it has a similar distribution of hydrophobic residues as region 244-285 in actin. Internal deletion of the sites in actin favor a model for cooperative binding of target proteins to CCT. Peptide mimetics, representing the binding regions, inhibit target polypeptide binding to CCT, suggesting that actin and tubulin contact similar CCT subunits. In addition, we show that actin recognition by class II chaperonins is different from that by class I.

Trastuzumab emtansine (T-DM1) renders HER2 <sup>+</sup> breast cancer highly susceptible to CTLA-4/PD-1 blockade (2015)

Targeted drug delivery with antibody-drug conjugates such as the HER2-directed ado-trastuzumab emtansine (T-DM1) has emerged as a powerful strategy for cancer therapy. We show that T-DM1 is particularly effective in eliciting antitumor immunity in patients with early breast cancer (WSG-ADAPT trial) and in a HER2-expressing orthotopic tumor model. In the latter, despite primary resistance to immunotherapy, combined treatment with T-DM1 and anti-CTLA-4/PD-1 (cytotoxic T lymphocyte-associated protein-4/programmed cell death protein-1) was curative because it triggered innate and adaptive immunity. Tumor rejection was accompanied by massive T cell infiltration, TH1 (T helper 1) cell polarization, and, notably, a substantial increase in regulatory T cells. Depletion of regulatory T cells resulted in inflammation and tissue damage, implying their essential role in protecting the host during therapy. This study provides insights into the mechanisms of T-DM1's therapeutic activity and a rationale for potential therapeutic combination strategies with immunotherapy.
Impact of time-of-flight on quantitative accuracy and volume determination in non-uniform phantoms (2009)

Objectives: PET Contrast Recovery depends on lesion’s background. Identical lesions in different backgrounds can recover differently due to different convergence and spill in/out effects. In this work we investigate the effects of Time-of-flight PET for identical lesions in different backgrounds in terms of both CRC and threshold based volume definition. \nMethods: A phantom with lesions and organ inserts simulating an obese patient at high count rate was acquired on a TOF-PET scanner. Identical lesions were placed both in hot and cold background. We performed listmode TOF and non-TOF reconstruction for varying scan times (30 and 60 s with 10 realizations each). We compared the performances of the two methods in measuring lesions volume by applying a 42% threshold method. CRC was calculated for all lesions in PET and TOF for a range of clinically used iterations. \nResults: TOF CRC converges faster and to higher values for all cold and hot lesions except one (23 mm), which converges 10 % higher for non-TOF. For this lesion the difference between TOF and non-TOF CRCs is less than 5 % at 3 iterations, clinically the most used on site. Identical lesions in different backgrounds converge to different values, the difference being 20% smaller for TOF. Volume thresholding for lesions in a cold background gives up to a 30% better volume estimation when using TOF. \nConclusions: TOF PET shows better characteristics for quantization tasks in different backgrounds and volume definition for cold background lesions. Count and contrast recovery is less depending on surrounding activity than with regular PET.

The spin rotation coefficients of the recoil proton in $\ensuremath{\pi}\ensuremath{-}N$ scattering are studied from the point of view of providing a means of resolving the present ambiguities in the phase-shift solution of the scattering cross section and the polarization of the recoil proton. There are six possible experiments four of which are independent, and the magnitude and the relative sign of the scattering matrix elements can uniquely be determined by four independent scattering experiments.

Review: apoptotic mechanisms in bacterial infections of the central nervous system (2012)

In this article we review the apoptotic mechanisms most frequently encountered in bacterial infections of the central nervous system (CNS). We focus specifically on apoptosis of neural cells (neurons and glia), and provide first an overview of the phenomenon of apoptosis itself and its extrinsic and intrinsic pathways. We then describe apoptosis in the context of infectious diseases and inflammation caused by bacteria, and review its role in the pathogenesis of the most relevant bacterial infections of the CNS.
The Induction of Staphylococcal  -Toxin by Histidine (1973)

SUMMARY: Addition of histidine to cultures of Staphylococcus aureus strain Wood 46 in a synthetic amino acid medium induced α-toxin formation, intracellularly within 10 min, and extracellularly within 15 min. The induction was inhibited by actino-mycin D, chloramphenicol, sodium azide and sodium nitrite. Histidinol behaved like histidine but several histidine analogues were without inductive properties. Histamine, which was metabolized to N-acetylhistamine, inhibited growth and α-toxin production in media without histidine, but its effect was overcome by histidine or histidinol. The culture fluids were examined by polyacrylamide gel electrophoresis. Precipitation with trichloracetic acid was used for concentration of the α-toxin, active toxin being recovered from the precipitate by dissolving in urea followed by heat precipitation. Three proteins appeared extracellularly in addition to α-toxin after induction with histidine.
Cdc6 and DNA replication: Limited to humble origins (1996)

The budding yeast Cdc6 protein is important for regulating DNA replication initiation. Cdc6p acts at replication origins, and cdc6-1 mutants arrest with unreplicated DNA and show elevated minichromosome loss rates. Overexpression of the related Cdc18 protein in fission yeast results in DNA rereplication; however, Cdc6p overexpression does not cause this result. A recent paper further defines the role of Cdc6p in DNA replication. Cdc6p only promotes DNA replication between the end of mitosis and late G1, and although the Cdc6 protein is highly unstable, neither degradation nor nuclear localization is critical for limiting DNA replication to this interval.
A Co-Processor Design for an Energy Efficient Reconfigurable Accelerator CMA (2015)

Cool Mega Array (CMA) is an energy efficient reconfigurable accelerator consisting of a large PE array with combinatorial circuits and a small microcontroller. In order to enhance the energy efficiency of the total system, a co-processor design of CMA called CMA-Geyser is proposed. By partly replacing the programmable microcontroller by the host processor Geyser with a dedicated hardware controller, the setting up for the CMA and data transfer can be efficiently done.The design using 65nm CMOS process is compared with an off-loading style multicore system Cube-1. By eliminating the data memory required in Cube-1, CMA-Geyser reduced 21.3% of semiconductor area. Also, it achieved about 2.7 times performance of Cube-1 by the efficient data communication between host and the accelerator.

Persistent Infection with <i>Pseudomonas aeruginosa</i> in Ventilator-associated Pneumonia (2008)

The increased apoptosis in neutrophils by the TTSS(+) isolates may explain the delay in eradication of Pseudomonas strains in patients with VAP. Short-course antimicrobial therapy may not be adequate in clearing the infection with a TTSS secretory phenotype.
Generation of coherent acoustic phonons in strained GaN thin films (2001)

Coherent acoustic phonon oscillations were generated and studied in strained GaN thin films. Inside the bulk GaN film, the longitudinal interference of an ultraviolet femtosecond pump pulse created periodic carrier distribution that screened out the strain-induced piezoelectric field and initiated the coherent longitudinal acoustic phonon oscillations corresponding to the carrier periods. The created coherent phonon oscillation modulated the piezoelectric field thus modified the absorption property of the GaN thin film through Franz–Keldysh effect. This time-dependent absorption modulation was reflected in the transmission variation of the followed probe pulses, resulting a long decay time ∼300 ps for the initiated coherent phonon oscillations.
Cell surface changes in the developing optic nerve of mice (1986)

A recently defined antibody to a cell surface protein, M6, inhibits neurite outgrowth in culture (Lagenaur, Fushiki, and Schachner: Soc. Neurosci. Abstr. 10:739, '84). In the developing mouse, the antibody stains all parts of the primary optic pathway at birth. Over the next week, staining is lost from the proximal segment of the optic nerve and a week later from the more central part of the nerve. By contrast staining persists through adulthood in the optic fiber layer of the retina. This means that single axons in the mature optic nerve express the antigen over only the proximal few millimeters of their course and over their terminal region. The results are discussed in relation to the overall maturation of the optic pathway and to the processes of membrane maturation and myelination.
Design, Testing, and Realization of a Distributed Fiber Optic Monitoring System to Assess Bending Characteristics Along Grouted Anchors (2019)

Grouted steel anchors combined with shotcrete layers at the surface are a common method to stabilize slopes and construction pits. Their design is based on the equilibrium consideration of a rigid body motion, and therefore, only tensile stresses are considered and accompanying forces, such as bending, are neglected. Modern approaches substitute the steel with wooden anchors, which show a sufficient tensile, but poor shear strength capacity. Distributed bending curves along the embedded anchors are required to design the optimal anchoring system, which, however, may not be measured using conventional sensing techniques. This paper reports about a distributed fiber optic sensing approach that enables the assessment of curvature and bending characteristics along grouted anchors. The designed system was tested within comprehensive laboratory investigations, in which various loading scenarios were applied to an instrumented, real-scale steel anchor. The suitability of the fiber optic sensing system was proven using image-based and geodetic total station measurements at the surface as well as by comparisons to theoretical beam models. In addition, three instrumented anchors were installed at a highway construction site and autonomously monitored over several weeks. The presented studies demonstrate the high potential of distributed fiber optic monitoring systems and their capability to extend traditional measurement methods in foundation engineering.

Application of Chromatography. XL. Riboflavin-activity of 6, 7-Dimethylribolumazine in Animal Body (1960)

There is a remarkable contradiction between the report of Katagiri, et al., that the liver of the cattle contains an enzyme which converts 6, 7-dimethylribolumazine into riboflavin, and that of Suzuoki, et al. that the former was nearly ineffective in their curative tests on the riboflavin-deficient rats. The present authors duplicated the method of Katagiri, et al., and confirmed that a phosphate buffer extract of the liver of the cattle transformed 6, 7-dimethylribolumazine into riboflavin in vitro. The same technique was applied to the liver of rats, but no increase of riboflavin was observed. Addition of diacetyl or sodium acetate as a carbon donor also gave the same result. These data are in good agreement with the result of Suzuoki, et al. in their tests on the whole body of the animal. Further the same experiments were attempted with the liver of rabbits and the result was the same as in the case of the liver of rats. On the other hand, a rabbit was fasted for a definite time and administered with 6, 7-dimethylribolumazine. The urine excreted before and after the administration was collected separately and subjected to paper partition chromatography. As a result, a distinct spot of riboflavin was observed in the "foreurine"but it became faint in the "after-urine, "and a conspicuous spot of 6, 7-dimethylribolumazine appeared in its stead. Although this result is merely qualitative, it is consistent with the result of the experiment on the liver homogenate of animals.
When Should We Worry About Supercharging in Formation Pressure While Drilling Measurements? (2005)

Abstract A model is described that is capable of simulating in detail the time variation of formation pressures measured while drilling, in situations where supercharging is significant. Simulation results are shown that illustrate the variation of supercharging pressures with formation permeability, drilling fluid filtration properties, and drilling fluid hydraulics. The model is used to explore how drilling operations influence the levels of supercharging when drilling two formations, widely separated along the well trajectory, and of significantly different permeabilities. The forward simulation capability presented is believed to be a useful aid to the planning, understanding and interpretation of formation pressure measurements while drilling.

Effect of laser color marking on the corrosion performance of stainless steel (2009)

With the continuous and rapid development of laser marking technology, the field of applications increases. In this work, the suitability of laser marking stainless steel is studied for writing product data on the outer surface of tubes during production. Generally, thermal oxidation of a stainless steel surface will deteriorate its pitting resistance and, even though corrosive media is usually inside the tubes, pitting attack from the outside can cause failures. Three commercial stainless steels, austenitic 316L (EN 1.4404 / UNS S31600) and duplex grades LDX 2101 (EN 1.4162 / UNS S32101) and 2304 (EN 1.4362, UNS S32304), were laser marked using two different parameter settings that resulted in two different oxide colors. The oxide composition and thickness were studied with glow discharge optical emission spectroscopy (GDOES) and the effect of surface appearance on the pitting corrosion resistance was determined using ASTM G150. It is shown that the oxide thickness affects the corrosion performance.
Approximate solution for electrical networks: When these are highly oscillatory (1928)

The general solution to the slightly damped network is expressed in terms of the undamped solution by means of series expansions. The first part of the paper gives a method for evaluating the complex roots of the determinantal equation, and the second part shows how the expansions of the first part may be correlated with the Heaviside formula to form the complete approximate solution. An example illustrates the application to a simple network.
Time-scale modification for speech coding (2000)

Time-scale modification (TSM) of speech refers to compressing or expanding the timescale of speech, while preserving the identity of the speaker (pitch, formant structure). It can be used for various applications, such as text-to-speech synthesis, film/sound-track post-synchronisation, foreign language learning, etc. In this study, we have investigated ifTSM can be beneficial to speech coding. The central idea is to compress the time-scale of a speech signal prior to coding, enabling usage of less bits, and to expand it by a reciprocal factor after decoding, to come to the original time-scale. For this purpose, we have built a speech coding system, incorporating a compressor, an expander, and standard speech coders. As opposed to traditional approaches, we propose the use of parametric modeling of unvoiced sounds. For evaluation purposes, we have used 25 compression 33 expansion. Comparison with some standard coders is presented. We conclude that speech coders with TSM perform worse than dedicated speech coders at comparable bit-rates. However, TSM can be beneficial in providing graceful degradation at higher bit-rates.
Ferroelectric and Piezoelectric Properties of 0.72Pb(Zr<sub>0.47</sub>Ti<sub>0.53</sub>)O<sub>3</sub>–0.28Pb[(Zn<sub>0.45</sub>Ni<sub>0.55</sub>)<sub>1/3</sub>Nb<sub>2/3</sub>]O<sub>3</sub>Thick Films for Energy Harvesting Device Application (2012)

The Ferroelectric and piezoelectric properties of 0.72Pb(Zr0.47Ti0.53)O3–0.28Pb[(Zn0.45Ni0.55)1/3Nb2/3]O3 (PZT–PZNN) piezoelectric thick films were investigated for application to energy harvesting devices. The PZT–PZNN thick films were fabricated by a conventional tape casting process. The sintered PZT–PZNN thick film was highly dense and flat when the annealed temperature was 1100 °C. It exhibited substantial ferroelectric and piezoelectric properties of Pr = 20.6 µC/cm2, d33 = 370 pC/N, εT33/ε0 = 1185, and kp = 0.44. Moreover, its d33·g33, which can characterize high energy density material, is as large as approximately 13050×10-15 m2/N. Therefore, the PZT–PZNN thick film can be a potential piezoelectric material for application to energy harvesting devices.
