High-power InAlGaAs-GaAs laser diode emitting near 731 nm (1997)

High-power, reliable operation of an InAlGaAs-based QW laser diode structure emitting near 731 nm and having a strained InAlGaAs active region is described. Threshold currents for coated 100 μm×1000 μm devices are 281 mA, and a peak power conversion efficiency of 41% is measured. Internal losses are measured to be 1.2 cm/sup -1/. A system for fiber-coupling two-dimensional continuous-wave (CW) arrays of these devices is demonstrated.
Soft Robots and Kangaroo Tails: Modulating Compliance in Continuum Structures Through Mechanical Layer Jamming (2016)

We present a new approach to creating biologically inspired, variable compliance continuum robot sections. Variable compliance is used to great effect in natural continuum structures, such as the arms of octopuses and the tails of kangaroos. We introduce a new approach to variable compliance robots based on mechanical layer jamming. The new design actively tightens and loosens mesh coverings of interleaved surface layers. This mechanical approach to layer jamming avoids problems arising from previously proposed pressure (pneumatic)-based layer jamming implementations. Experiments using a prototype of the new design demonstrate the potential of the approach to produce novel soft and compliant robots.
1.5 W operation of superluminescent diode with highly strained GaInAs/GaAs quantum well emitting at 1.2 μm band (2002)

Presents the high power operation of a tapered superluminescent diode with highly strained GaInAs/GaAs QWs emitting at in the 1.2 /spl mu/m band. As its background, we achieved the wavelength extension of GaInAs/GaAs QWs beyond 1.2 /spl mu/m by using highly strained QWs. Also, we presented low threshold and excellent temperature characteristics of 1.2 /spl mu/m QW lasers, and their application for single mode fiber datacom. However, there have been difficulties in realizing high power light sources in the wavelength range of 1.1-1.2 /spl mu/m. They may open up new applications, which include pumping for 1.2-1.3 /spl mu/m Raman fiber amplifiers, free-space LANs and so on.

Statistical pattern recognition (2000)

Pattern recognition problems emerge constantly in our everyday life. The ring of the telephone triggers an on-line pattern recognition problem: who might this be? Hearing the voice on the line we are almost always able to tell who this is, no matter that the line might be noisy, or the person at the other end might have a cold. Humans easily identify faces, speakers, smells — tasks that are still a challenge for a computer. When we are able to instruct the computer how to label the objects into the prespecified groups, the problem becomes routine. Pattern recognition is about those problems that are still not algorithmically clear-cut. Examples of pattern recognition problems are: classification of crops and soil types from remote-sensing images; detection of clustered microcalcifications on mammograms; optical character recognition (OCR); classification of airmass for predicting a thunderstorm flood; discrimination between stars and galaxies in sky images; etc.
Inborn Errors of Metabolism Causing Homocysteinemia and Related Vascular Involvement (1989)

Sulfur amino acids have been implicated in the pathogenesis of thromboembolic vascular disease, and observations of patients with several inborn errors of metabolism have led to the 'homocysteine theory of arteriosclerosis'. Homocysteine is an intermediate in the transsulfuration pathway and it enters into several other reactions, some of which involve transfer of methyl groups. An abnormally high concentration of homocysteine in the blood causes homocystinuria. Deficiency of cystathionine beta-synthase is the most frequent cause of homocystinuria. Patients with this disorder are at risk for early vascular occlusions. Treatment with vitamin B6 of patients who are biochemically responsive to this vitamin reduces the risk of thromboembolism. Clinical or pathologic evidence of early vascular disease has also been provided in patients with homocysteinemia due to deficient (re)methylation of homocysteine to methionine. This may be caused by a deficiency of 5,10-methylenetetrahydrofolate reductase or by a deficient synthesis of cobalamins.

Soft Tissue Augmentation of Periorbital Fine Lines and the Orbital Groove with Zyderm‐I and Fine‐Gauge Needles (1992)

A new procedure utilizing Zyderm-I (Collagen Biomedical, Palo Alto, CA) and a 32-gauge needle for augmentation of the periorbital fine lines and the orbital groove is described. This advanced soft tissue augmentation technique is described in detail in 30 patients with before, after, and 1-week post-augmentation photographs presented by the author. This technique requires familiarity with soft tissue augmentation and the use of collagen injectable materials as well as specific training on a one-to-one basis with someone experienced with this particular technique.
MemHC: An Optimized GPU Memory Management Framework for Accelerating Many-body Correlation (2022)

The many-body correlation function is a fundamental computation kernel in modern physics computing applications, e.g., Hadron Contractions in Lattice quantum chromodynamics (QCD). This kernel is both computation and memory intensive, involving a series of tensor contractions, and thus usually runs on accelerators like GPUs. Existing optimizations on many-body correlation mainly focus on individual tensor contractions (e.g., cuBLAS libraries and others). In contrast, this work discovers a new optimization dimension for many-body correlation by exploring the optimization opportunities among tensor contractions. More specifically, it targets general GPU architectures (both NVIDIA and AMD) and optimizes many-body correlation’s memory management by exploiting a set of memory allocation and communication redundancy elimination opportunities: first, GPU memory allocation redundancy : the intermediate output frequently occurs as input in the subsequent calculations; second, CPU-GPU communication redundancy : although all tensors are allocated on both CPU and GPU, many of them are used (and reused) on the GPU side only, and thus, many CPU/GPU communications (like that in existing Unified Memory designs) are unnecessary; third, GPU oversubscription: limited GPU memory size causes oversubscription issues, and existing memory management usually results in near-reuse data eviction, thus incurring extra CPU/GPU memory communications. Targeting these memory optimization opportunities, this article proposes MemHC, an optimized systematic GPU memory management framework that aims to accelerate the calculation of many-body correlation functions utilizing a series of new memory reduction designs. These designs involve optimizations for GPU memory allocation, CPU/GPU memory movement, and GPU memory oversubscription, respectively. More specifically, first, MemHC employs duplication-aware management and lazy release of GPU memories to corresponding host managing for better data reusability. Second, it implements data reorganization and on-demand synchronization to eliminate redundant (or unnecessary) data transfer. Third, MemHC exploits an optimized Least Recently Used (LRU) eviction policy called Pre-Protected LRU to reduce evictions and leverage memory hits. Additionally, MemHC is portable for various platforms including NVIDIA GPUs and AMD GPUs. The evaluation demonstrates that MemHC outperforms unified memory management by \( 2.18\times \) to \( 10.73\times \) . The proposed Pre-Protected LRU policy outperforms the original LRU policy by up to \( 1.36\times \) improvement. 1

Fourier analysis for correction of thermograms obtained with a heat flow microcalorimeter of high stability (for adsorption and decomposition study) (1976)

A description is given of a heat flow microcalorimeter designed to study the adsorption of vapours on solids and their subsequent decomposition reaction rates. The usefulness of electrical analogues in finding stability improvements is stressed. The thermograms being necessarily distorted by thermal inertia may be corrected by means of Fourier analysis. The performance of Fourier analysis is traced for a number of test experiments.
<i>In vitro</i> studies evaluating the effects of biofilms on wound‐healing cells: a review (2017)

Chronic wounds are characterized as wounds that have failed to proceed through the well-orchestrated healing process and have remained open for months to years. Open wounds are at risk for colonization by opportunistic pathogens. Bacteria that colonize the open wound bed form surface-attached, multicellular communities called biofilms, and chronic wound biofilms can contain a diverse microbiota. Investigators are just beginning to elucidate the role of biofilms in chronic wound pathogenesis, and have simplified the complex wound environment using in vitro models to obtain a fundamental understanding of the impact of biofilms on wound-healing cell types. The intent of this review is to describe current in vitro methodologies and their results. Investigations started with one host cell-type and single species biofilms and demonstrated that biofilms, or their secretions, had deleterious effects on wound-healing cells. More complex systems involved the use of multiple host cell/tissue types and single species biofilms. Using human skin-equivalent tissues, investigators demonstrated that a number of different species can grow on the tissue and elicit an inflammatory response from the tissue. A full understanding of how biofilms impact wound-healing cells and host tissues will have a profound effect on how chronic wounds are treated.
Hypercontractile Properties of Cardiac Muscle Fibers in a Knock-in Mouse Model of Cardiac Myosin-binding Protein-C (2001)

Myosin-binding protein-C (MyBP-C) is a component of all striated-muscle sarcomeres, with a well established structural role and a possible function for force regulation. Multiple mutations within the gene for cardiac MyBP-C, one of three known isoforms, have been linked to familial hypertrophic cardiomyopathy. Here we generated a knock-in mouse model that carries N-terminal-shortened cardiac MyBP-C. The mutant protein was designed to have a similar size as the skeletal MyBP-C isoforms, whereas known myosin and titin binding sites as well as the phosphorylatable MyBP-C motif were not altered. We have shown that mutant cardiac MyBP-C is readily incorporated into the sarcomeres of both heterozygous and homozygous animals and can still be phosphorylated by cAMP-dependent protein kinase. Although histological characterization of wild-type and mutant hearts did not reveal obvious differences in phenotype, left ventricular fibers from homozygous mutant mice exhibited an increased Ca(2+) sensitivity of force development, particularly at lower Ca(2+) concentrations, whereas maximal active force levels remained unchanged. The results allow us to propose a model of how cMyBP-C may affect myosin-head mobility and to rationalize why N-terminal mutations of the protein in some cases of familial hypertrophic cardiomyopathy could lead to a hypercontractile state.
Auctions and Bid Rigging (2015)

Abstract This chapter surveys the theoretical and empirical literature on bid rigging in auctions. In particular, it reviews the theory and practice of bidding rings in one-shot auctions and in repeated auctions. The main theme is how the type of auction, whether it is first-price or second-price, sealed bid or oral, affects the incentive of bidders to collude and the way in which they collude.
FWM crosstalk suppression using wavelength grouping in 25-GHz-spaced 10Gbps-based WDM transmission over NZ-DSF in C-band (2003)

<i>Pleurotus tuber-regium</i>Polysaccharides Attenuate Hyperglycemia and Oxidative Stress in Experimental Diabetic Rats (2012)

Pleurotus tuber-regium contains polysaccharides that are responsible for pharmacological actions, and medicinal effects of these polysaccharides have not yet been studied in diabetic rats. We examined the antidiabetic, antihyperlipidemic, and antioxidant properties of P. tuber-regium polysaccharides in experimental diabetic rats. Forty rats were equally assigned as diabetic high-fat (DHF) diet and polysaccharides treated DHF groups (DHF+1P, DHF+2P, and DHF+3P, 20 mg/kg bodyweight/8-week). Diabetes was induced by chronic low-dose streptozotocin injections and a high-fat diet to mimic type 2 diabetes. Polysaccharides (1P, 2P, and 3P) were extracted from three different strains of P. tuber-regium. Fasting blood glucose and glycosylated hemoglobin (HbA1c) levels substantially decreased, while serum insulin levels were restored by polysaccharides treatment compared to DHF. Furthermore, plasma total cholesterol, triglycerides, and low-density lipoprotein levels were significantly (P < 0.01) lower in polysaccharide groups. High-density lipoprotein levels were attenuated with polysaccharides against diabetes condition. Polysaccharides inhibited (P < 0.01) the lipid peroxidation index (malondialdehyde), and restored superoxide dismutase and glutathione peroxidase activities in the liver of diabetic rats. The antihyperglycemic property of polysaccharides perhaps boosts the antioxidant system that attenuates oxidative stress. We emphasize that P. tuber-regium polysaccharides can be considered as an alternative medicine to treat hyperglycemia and oxidative stress in diabetic rats.

Dialysis in neonates with inborn errors of metabolism (1999)

Integrity (2006)

The next virtue in Rand's ethics, integrity, also enjoys esteem in conventional morality. While people may differ over exactly what constitutes a breach of integrity, to impugn a person's integrity is widely seen as among the most grave sorts of censure possible. The reason why Rand considers integrity important, however, is not the reason usually given. Integrity is proper neither inherently nor because of its value to others. Rather, Rand recognizes integrity as an instrument of rational egoism. Maintaining one's integrity is essential to achieving objective values and flourishing. To see this, we shall again proceed to consider what integrity is, why it is a virtue, and the specific demands that it places on us.
Rab5-stimulated Up-regulation of the Endocytic Pathway Increases Intracellular β-Cleaved Amyloid Precursor Protein Carboxyl-terminal Fragment Levels and Aβ Production (2003)

We previously identified abnormalities of the endocytic pathway in neurons as the earliest known pathology in sporadic Alzheimer's disease (AD) and Down's syndrome brain. In this study, we modeled aspects of these AD-related endocytic changes in murine L cells by overexpressing Rab5, a positive regulator of endocytosis. Rab5-transfected cells exhibited abnormally large endosomes immunoreactive for Rab5 and early endosomal antigen 1, resembling the endosome morphology seen in affected neurons from AD brain. The levels of both Abeta40 and Abeta42 in conditioned medium were increased more than 2.5-fold following Rab5 overexpression. In Rab5 overexpressing cells, the levels of beta-cleaved amyloid precursor protein (APP) carboxyl-terminal fragments (betaCTF), the rate-limiting proteolytic intermediate in Abeta generation, were increased up to 2-fold relative to APP holoprotein levels. An increase in beta-cleaved soluble APP relative to alpha-cleaved soluble APP was also observed following Rab5 overexpression. BetaCTFs were co-localized by immunolabeling to vesicular compartments, including the early endosome and the trans-Golgi network. These results demonstrate a relationship between endosomal pathway activity, betaCTF generation, and Abeta production. Our findings in this model system suggest that the endosomal pathology seen at the earliest stage of sporadic AD may contribute to APP proteolysis along a beta-amyloidogenic pathway.
Ca<sub><i>x</i></sub>La<sub>1–<i>x</i></sub>Mn<sub>1–<i>y</i></sub>M<sub><i>y</i></sub>O<sub>3−δ</sub> (M = Mg, Ti, Fe, or Cu) as Oxygen Carriers for Chemical-Looping with Oxygen Uncoupling (CLOU) (2013)

Perovskite materials of the type CaxLa1–xMn1–yMyO3−δ (M = Mg, Ti, Fe, or Cu) have been investigated as oxygen carriers for the chemical-looping with oxygen uncoupling (CLOU) process. The oxygen carrier particles were produced by mechanical homogenization of primary solids in a rotary evaporator, followed by extrusion and calcination at 1300 °C for 6 h. The chemical-looping characteristics of the substituted perovskites developed in this work were evaluated in a laboratory-scale fluidized-bed reactor in the temperature range of 900–1000 °C during alternating reducing and oxidizing conditions. The oxygen carriers showed oxygen releasing behavior (CLOU) in an inert atmosphere between 900 and 1000 °C. In addition, their reactivity with methane was high, approaching complete gas yield for all of the materials at 950 °C, with the exception being the Cu-doped perovskite, which defluidized during reduction. The rates of oxygen release were also investigated using devolatilized wood char as solid fuel and were found to be similar. The required solids inventory in the fuel reactor for the perovskite oxygen carriers is estimated to be 325 kg/MWth. All of the formulations exhibited high rates of oxidation and a high degree of stability, with no particle fragmentation or agglomeration. The high reactivity and favorable oxygen uncoupling properties make these oxygen carriers promising candidates for the CLOU process.
Ultra low phase noise parametric frequency divider for highest performance microwave- and millimeter-wave frequency sources (1995)

A two stage parametric frequency divider (900/450/225MHz) with ultra low phase noise for application in the frequency generation section of advanced microwave and millimeterwave frequency sources has been developed. The necessity for the usage of this type of divider in local oscillator PLL circuits is described. The article focusses on the extensive use of modem CAE tools based on precise diode parameter extraction, that leads to an excellent agreement between simulation and measurement results. The divider consists of two halvers in a series configuration, including low cost hyperabrupt tuning varactors, an amplifier stage and only a few lumped elements for impedance matching. The output signal is calculated in frequency and time domain. Recommended minimum input power, conversion loss and power threshold behaviour are predetermined. The measured phase noise floor is compared to a digital frequency divider.
