Fabrication of low power micro - heater for micro - gas sensor 2 . Characteristics of micro - gas sensor (1997)

A new planar-type microsensor, which had a platinum heater and a sensing layer on the same plane was fabricated on silicon substrate with stress-relieved PSG(phosphosilicate glass)/Si₃N₄(8(10nm/150nm) diaphragm. The proposed planar-type microsensor could be fabricated by simple silicon process using only 3 masks for photolithography process compared with 5 or 6 masks of the typical micro-gas sensor. The thermal properties of the microsensor from thermal simulation were compared with those of the fabricated microheater. Although there are some discrepancy between the simulation result and the result from the fabricated microheater, the thermal simulation by FEM was proved to be an useful method to evaluate the thermal properties of microheater. The sensing characteristics of the fabricated microsensor with the planar-type heater were investigated also.

TrkA Amino Acids Controlling Specificity for Nerve Growth Factor (2000)

Neurotrophins are important for the development and maintenance of the vertebrate nervous system, mediating their signal into the cell by specific interaction with tyrosine kinase receptors of the Trk family. The extracellular portion of the Trk receptors has been previously proposed to consist of a cysteine-rich motif, a leucine-rich motif, a second cysteine-rich motif followed by two immunoglobulin-like domains. Earlier studies have shown that a major neurotrophin-binding site in the Trk receptors resides in the second immunoglobulin-like domain. Although the individual amino acids in TrkA involved in binding to nerve growth factor (NGF) and those in TrkC involved in binding to neurotrophin-3 have been mapped in this domain, the Trk amino acids that provide specificity remained unclear. In this study, a minimum set of residues in the human TrkC second immunoglobulin-like domain, which does not bind nerve growth factor (NGF), were substituted with those from human TrkA. The resulting Trk variant recruited binding of NGF equivalent to TrkA, maintained neurotrophin-3 binding equivalent to TrkC, and also bound brain-derived neurotrophin, although with lower affinity compared with TrkB. This implies that the amino acids in the second immunoglobulin-like domain that determine Trk specificity are distinct for each Trk.
Secondary metabolite arsenal of an opportunistic pathogenic fungus (2016)

Aspergillus fumigatus is a versatile fungus able to successfully exploit diverse environments from mammalian lungs to agricultural waste products. Among its many fitness attributes are dozens of genetic loci containing biosynthetic gene clusters (BGCs) producing bioactive small molecules (often referred to as secondary metabolites or natural products) that provide growth advantages to the fungus dependent on environment. Here we summarize the current knowledge of these BGCs-18 of which can be named to product-their expression profiles in vivo, and which BGCs may enhance virulence of this opportunistic human pathogen. Furthermore, we find extensive evidence for the presence of many of these BGCs, or similar BGCs, in distantly related genera including the emerging pathogen Pseudogymnoascus destructans, the causative agent of white-nose syndrome in bats, and suggest such BGCs may be predictive of pathogenic potential in other fungi.This article is part of the themed issue 'Tackling emerging fungal threats to animal health, food security and ecosystem resilience'.
Cystoscopy and Systematic Bladder Tissue Sampling in Predicting pT0 Bladder Cancer: A Prospective Trial (2021)

Approximately 1 of 4 patients with seeT0 at the time of radical cystectomy harbored residual muscle invasive bladder cancer. These prospective data definitively confirm major limitations of endoscopic assessment for pT0 bladder cancer. Future work should focus on novel imaging and biomarker strategies to optimize evaluations before radical cystectomy for improved decision making regarding bladder preservation.
Numerical Processing for Precision Plate Bending by Computer Aided Line-heating System (1996)

A computer aided plate bending system is under developing in authors' company to realize the automatic forming of shell plates in shipyards. The Finite Element Method based on the theory of inherent strain has been proved to be a very powerful approach to obtain proper inherent strains which govern deformation. In practice, the inherent strains are approximately achieved through combination of many single heating lines, leaving certain geometric error.In this paper, geometric errors produced in two processes, and the ways how to reduce them are discussed. In the stage of planning heating lines, converting inherent strains into heating lines causes some error in deformation. It is because that the inherent strains calculated from plate expansion by FEM could be arbitrary while the shape and magnitude of the inherent strains produced by heating lines are of limited types. Iterating calculation is used to eliminate this error. Another kind of error comes from heating stage. The plastic strains produced in real plate are commonly different from those obtained from experiments even though heat input and heating time are same. Some factors, such as residual stress, initial curvature and effect of heating position have fairly large influences. They are usually too complicated to be predicted in planning stage. Instead of separate investigations, a statistical method is proposed to evaluate whole system according to the deformation resulting from previous line-heating. Period-by-period prediction and refining arrangement are therefore possible.A saddle shaping experiment shows that the geometric errors in both the stages are very large. And the above mentioned methods are proved to be effective in decreasing the errors.
[Cardiorenal syndrome, current understanding]. (2009)

The term cardiorenal syndrome (CRS) has increasingly been used in recent years without a constant meaning and a well accepted definition. To include the vast array of interrelated derangements, and to stress the bi-directional nature of the heart-kidney interactions, the classification of the cardiorenal syndrome includes today five sub-types whose etymology reflects the primary and secondary pathology, the time-frame and simultaneous cardiac and renal co-dysfunction secondary to systemic disease. The cardiorenal syndrome can be generally defined as a pathophysiologic disorder of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction in the other organ. Type I CRS reflects an abrupt worsening of cardiac function (e.g. acute cardiogenic shock or decompensated congestive heart failure) leading to acute kidney injury. Type II CRS describes chronic abnormalities in cardiac function (e.g. chronic congestive heart failure) causing progressive and permanent chronic kidney disease. Type III CRS consists in an abrupt worsening of renal function (e.g. acute kidney ischaemia or glomerulonephritis) causing acute cardiac disorder (e.g. heart failure, arrhythmia, ischemia). Type IV CRS describes a state of chronic kidney disease (e.g. chronic glomerular disease) contributing to decreased cardiac function, cardiac hypertrophy and/or increased risk of adverse cardiovascular events. Type V CRS reflects a systemic condition (e.g. diabetes mellitus, sepsis) causing both cardiac and renal dysfunction. Biomarkers can help to characterize the subtypes of the CRS and to indicate treatment initiation and effectiveness.
Computational Human Torso Model Validation for Frontal Blunt Trauma (2018)

Recent research on behind-armor blunt trauma (BABT) has focused on the personal protection offered by lightweight armor. A finite element analysis was performed to improve the biofidelity of the US Army Research Laboratory (ARL) human torso model to prepare for simulating blunt chest impacts and BABT. The overly stiff linear elastic material models for the torso were replaced with material characterizations drawn from current literature. FE torso biofidelity was determined by comparing peak force, force-compression, peak compression, and energy absorption data with cadaver responses to a 23.5 kg pendulum impacting at the sternum at 6.7 m/s. Nonlinear foam, viscous foam, soft rubbers, fibrous hyperelastic rubbers, and low moduli elastic material were considered as material models for the flesh, organs, and bones. Simulations modifying one tissue type revealed that the flesh characterization was most crucial for predicting compression and force, followed closely by the organs characterizations. Combining multiple tissue modifications allowed the FE torso to mimic the cadaveric torsos by reducing peak force and increasing chest compression and energy absorption. Limitations imposed by the Lagrangian finite element approach are discussed with potential workarounds described. Proposed future work is split between considering additional impact scenarios accounting for position and biomaterial variability.

Mechanical properties and cytotoxicity of a resorbable bioactive implant prepared by rapid prototyping technique (2013)

Bioceramic processing using rapid prototyping technique (RPT) results in a fragile device that requires thermal treatment to improve the mechanical properties. This investigation evaluates the effect of thermal treatment on the mechanical, porosity, and bioactivity properties as well as the cytotoxicity of a porous silica‐calcium phosphate nanocomposite (SCPC) implant prepared by RPT. Porous SCPC implant was subject to 3‐h treatment at 800°C, 850°C, or 900°C. The compressive strength (s) and modulus of elasticity (E) were doubled when the sintering temperature is raised from 850 to 900°C measuring (s = 15.326 ± 2.95 MPa and E = 1095 ± 164 MPa) after the later treatment. The significant increase in mechanical properties takes place with minimal changes in the surface area and the percentage of pores in the range 1–356 μm. The SCPC implant prepared at 900°C was loaded with rh‐BMP‐2 and grafted into a segmental defect in the rabbit ulna. Histology analyses showed highly vascularized bone formation inside the defect. Histopathological analyses of the liver, spleen, kidney, heart, and the lung of rabbits grafted with and without SCPC demonstrated healthy tissues with no signs of toxicity or morphology alterations. Results of the study suggest that it is possible to engineering the mechanical properties of the SCPC implant without compromising its bioactivity. The enhanced bone formation inside the porous SCPC facilitated cell‐mediated graft resorption and prohibited any accumulation of the material in the body organs. © 2013 Wiley Periodicals, Inc.

High conductivity Sepia melanin ink films for environmentally benign printed electronics (2022)

Melanins (from the Greek μέλας, mélas, black) are bio-pigments ubiquitous in flora and fauna. Eumelanin is an insoluble brown-black type of melanin, found in vertebrates and invertebrates alike, among which Sepia (cuttlefish) is noteworthy. Sepia melanin is a type of bio-sourced eumelanin that can readily be extracted from the ink sac of cuttlefish. Eumelanin features broadband optical absorption, metal-binding affinity and antioxidative and radical-scavenging properties. It is a prototype of benign material for sustainable organic electronics technologies. Here, we report on an electronic conductivity as high as 10<sup>-3</sup> S cm<sup>-1</sup> in flexographically printed Sepia melanin films; such values for the conductivity are typical for well-established high-performance organic electronic polymers but quite uncommon for bio-sourced organic materials. Our studies show the potential of bio-sourced materials for emerging electronic technologies with low human- and eco-toxicity.
Low-threshold vertical-cavity surface-emitting lasers based on oxide-confinement and high contrast distributed Bragg reflectors (1997)

The interest in low-threshold vertical-cavity surface-emitting lasers (VCSEL's) is increased by the demonstration of the small size, low loss optical mode due to oxide-confinement in the Fabry-Perot microcavity laser. Intense recent work in this area has resulted in numerous record breaking demonstrations of low-threshold current, high wall-plug efficiency, and high speed. In this paper, we discuss the impact of the dielectric cavity design to enhance control of the optical mode. We argue that high contrast dielectric mirrors can become an important design approach, especially for small apertures limited by diffraction loss. Experimental results are compared for different types of mirror and aperture designs.
Analyses of Histone Proteoforms Using Front-end Electron Transfer Dissociation-enabled Orbitrap Instruments (2016)

Histones represent a class of proteins ideally suited to analyses by top-down mass spectrometry due to their relatively small size, the high electron transfer dissociation-compatible charge states they exhibit, and the potential to gain valuable information concerning combinatorial post-translational modifications and variants. We recently described new methods in mass spectrometry for the acquisition of high-quality MS/MS spectra of intact proteins (Anderson, L. C., English, A. M., Wang, W., Bai, D. L., Shabanowitz, J., and Hunt, D. F. (2015) Int. J. Mass Spectrom. 377, 617-624). Here, we report an extension of these techniques. Sequential ion/ion reactions carried out in a modified Orbitrap Velos Pro/Elite(TM) capable of multiple fragment ion fills of the C-trap, in combination with data-dependent and targeted HPLC-MS experiments, were used to obtain high resolution MS/MS spectra of histones from butyrate-treated HeLa cells. These spectra were used to identify several unique intact histone proteoforms with up to 81% sequence coverage. We also demonstrate that parallel ion parking during ion/ion proton transfer reactions can be used to separate species of overlapping m/z that are not separated chromatographically, revealing previously indiscernible signals. Finally, we characterized several truncated forms of H2A and H2B found within the histone fractions analyzed, achieving up to 93% sequence coverage by electron transfer dissociation MS/MS. Results of follow-up in vitro experiments suggest that some of the truncated histone H2A proteoforms we observed can be generated by cathepsin L, an enzyme known to also catalyze clipping of histone H3.
Sodium, volume and pressure control in haemodialysis patients for improved cardiovascular outcomes (2020)

Chronic volume overload is pervasive in patients on chronic haemodialysis and substantially increases the risk of cardiovascular death. The rediscovery of the three-compartment model in sodium metabolism revolutionizes our understanding of sodium (patho-)physiology and is an effect modifier that still needs to be understood in the context of hypertension and end-stage kidney disease. Assessment of fluid overload in haemodialysis patients is central yet difficult to achieve, because traditional clinical signs of volume overload lack sensitivity and specificity. The highest all-cause mortality risk may be found in haemodialysis patients presenting with high fluid overload but low blood pressure before haemodialysis treatment. The second highest risk may be found in patients with both high blood pressure and fluid overload, while high blood pressure but normal fluid overload may only relate to moderate risk. Optimization of fluid overload in haemodialysis patients should be guided by combining the traditional clinical evaluation with objective measurements such as bioimpedance spectroscopy in assessing the risk of fluid overload. To overcome the tide of extracellular fluid, the concept of time-averaged fluid overload during the interdialytic period has been established and requires possible readjustment of a negative target post-dialysis weight. 23Na-magnetic resonance imaging studies will help to quantitate sodium accumulation and keep prescribed haemodialytic sodium mass balance on the radar. Cluster-randomization trials (e.g. on sodium removal) are underway to improve our therapeutic approach to cardioprotective haemodialysis management.

WCDMA Uplink Load Estimation With Generalized Rake Receivers (2012)

A generalized rake (G-rake) receiver creates link gains by interference suppression. To fully exploit these gains for the enhancement of cellular system performance, the scheduler of a wideband code-division multiple-access (WCDMA) radio base station needs estimates of the uplink load after G-rake processing. This paper, therefore, proposes algorithms that estimate this load with a bandwidth as high as the channel estimation bandwidth. Link simulations support the obtained results.
Suppression of intrinsic bistability by the exchange-correlation effect in resonant-tunneling structures (1994)

We have performed a full self-consistent many-body study, within the framework of the random-phase approximation, on the intrinsic bistability in double-barrier resonant-tunneling structures. We found that the exchange-correlation effect can suppress the bistability which may be produced by the electrostatic feedback to the potential by the charge accumulated in the quantum well. Our self-consistent numerical results explain the existing contradiction between the affirmative theoretical prediction and the negative experimental observation on the occurrence of bistability in certain samples.

TRIUMF CYCLOTRON VACUUM SYSTEM UPGRADE AND OPERATIONAL EXPERIENCE (2009)

The replacement of the 30-year-old Philips cryogenerator with a modern LINDE-1630 helium refrigerator is an important component of TRIUMF’s ongoing 500 MeV cyclotron refurbishing program. Two 10.7 m long cryopanels are cooled with liquid helium rather than with 17 K helium gas, as was the case with the cryogenerator. This has increased the pumping speed and, respectively, improved the vacuum in the approximately 100 m 3 cyclotron tank. Additionally, the thermal shield, previously cooled with helium gas, is now cooled with liquid nitrogen. These changes have resulted in increased reliability of the cyclotron vacuum system and, consequently, longer operation periods without maintenance. The new refrigeration unit was commissioned in September 2007. The results from over one year of operational experience are discussed. Also, data on hydrogen cryopumping is presented.
NOVEL ENZYMATIC POLYETHYLENE OXIDE-POLYPHENOL SYSTEM FOR IONIC CONDUCTIVITY (2002)

Abstract Phenol formaldehyde resins are of interest for different industrial and electronic applications. However, the toxic nature of formaldehyde and the extreme reaction conditions for the synthesis of these polymers have severely limited their use in today's markets. We present here a novel, biocatalytic approach where the enzyme horseradish peroxidase is used to polymerize phenol in the presence of a template such as polyethylene oxide. Here the template assists as a surfactant that can both emulsify the phenol and polyphenol chains during polymerization and provide water/solvent solubility of the final polyphenol/template complex. The reactants and the reaction conditions of this method are mild and result in high molecular weight, electrically and optically active, water-solvent soluble complexes of polyphenol and the template used. High molecular weight water-soluble polyphenol/polyethylene oxide complexes were formed.
