Unique properties of quantum dot lasers (2004)

Quantum dot (QD) lasers on GaAs substrates demonstrate parameters improved over quantum well-based devices and operate in an extended wavelength range. Pseudomorphic 1.3 /spl mu/m InAs-GaAs QD lasers demonstrate low threshold current density (J/sub th//sup 300 K/<100 A/cm/sup 2/), high differential efficiency (/spl eta//sub diff/>80%), and low losses (/spl alpha/<1.5 cm/sup -1/) - all realized in the same device. Characteristic temperature for the threshold current is /spl sim/170 K up to 70/spl deg/C. Reduced linewidth enhancement factor is advantageous for low-chirp operation and makes it possible to suppress completely beam filamentation up to stripe widths /spl sim/100 /spl mu/m. GaAs-based 1.31 /spl mu/m QD vertical-cavity surface-emitting lasers (VCSELs) with 8 /spl mu/m oxide aperture emit up to 1.2 mW continuous wave (CW) optical power. First 1.5 /spl mu/m QD lasers on GaAs substrates with high quantum efficiency (/spl eta//sub i/>60-70%) and low losses (/spl alpha/<3-4 cm/sup -1/) are fabricated.

Cellulose phosphates as biomaterials. II. Surface chemical modification of regenerated cellulose hydrogels (2001)

Abstract Cellulose regenerated by the viscose process was previously investigated as an implantable material in orthopedic surgery. It was envisaged to take advantage not only of its good matching with mechanical properties of bone but also of its hydroexpansivity, therefore allowing a satisfactory fixation to hard tissue. Both the osteoconduction and the lack of osteoinduction of this material were demonstrated. Grafting of phosphate groups was then envisaged as the means to render cellulose more suitable for orthopedic applications by enhancing its bioactivity. In the present work, the previously optimized phosphorylation reaction was successfully adapted to the surface modification of regenerated cellulose. Modified materials were characterized by XPS, FTIR, and 31 P MAS NMR spectroscopic studies, and contact angle measurements, revealing the chemical bond between phosphate groups and cellulose, as well as the hydrophilic nature of phosphorylated materials, which increases with increasing phosphate contents. Water swelling and resistance to gamma sterilization were assessed as well, showing that phosphorylated materials swell considerably in water and were not affected when sterilization was carried out under a nitrogen atmosphere. The increase in surface roughness attributed to chemical modification was demonstrated through laser rugosimetry measurements. © 2001 John Wiley &amp; Sons, Inc. J Appl Polym Sci 82: 3354–3365, 2001
Induction and Differentiation of IL-10–Producing Regulatory B Cells from Healthy Blood Donors and Rheumatoid Arthritis Patients (2017)

The most important feature of B cells is the production of Abs upon activation; additionally, B cells produce pro- and anti-inflammatory cytokines in response to certain stimuli. IL-10-producing B cells represent a major subset of regulatory B cells (Bregs) that suppress autoimmune and inflammatory responses. B cells play a crucial role in the development and maintenance of the chronic inflammatory autoimmune disease rheumatoid arthritis (RA); however, controversial data are available on IL-10- producing Bregs in RA. Our aim was to identify the optimal conditions that induce IL-10<sup>+</sup> Bregs and, furthermore, to shed light on the signaling pathways that are responsible for their expansion. The results show that dual stimulation by CpG and CD40L for 48 h is optimal for IL-10 induction, and this can be synergistically boosted by IL-21. We identified the CD19<sup>+</sup>CD27<sup>+</sup> memory B cell population as the major source of IL-10<sup>+</sup> Bregs. We detected significantly fewer CD19<sup>+</sup>CD27<sup>+</sup>IL-10<sup>+</sup> cells in RA patients compared with healthy controls, and these were functionally defective in suppressing IFN-γ production by CD4<sup>+</sup> T cells in coculture. IL-21 drastically increased the number of IL-10<sup>+</sup> Bregs within the CD19<sup>+</sup>CD27<sup>+</sup> and CD19<sup>+</sup>CD27<sup>-</sup> populations; furthermore, it induced the appearance of IL-10<sup>+</sup>Blimp-1<sup>+</sup> plasmablasts. Monitoring the phosphorylation of key signaling molecules revealed that activation of ERK, p38, and CREB is indispensable for the induction of IL-10 production, whereas phosphorylation of STAT3 further enhances IL-10 expression in human Bregs. We conclude that CREB and STAT3 are the key transcription factors responsible for the expansion and differentiation of human IL-10-producing Bregs.
Development of a Test Battery for Evaluating Speech Perception in Complex Listening Environments: Effects of Sensorineural Hearing Loss (2018)

A test battery that includes the TC+Rev and the N0Sπ conditions would be useful in identifying individuals with hearing loss with speech-in-noise deficits in everyday communication.
Fuzzy-assisted social-based routing for urban vehicular environments (2011)

In the autonomous environment of Vehicular Ad hoc NETwork (VANET), vehicles randomly move with high speed and rely on each other for successful data transmission process. The routing can be difficult or impossible to predict in such intermittent vehicles connectivity and highly dynamic topology. The existing routing solutions do not consider the knowledge that behaviour patterns exist in real-time urban vehicular networks. In this article, we propose a fuzzy-assisted social-based routing (FAST) protocol that takes the advantage of social behaviour of humans on the road to make optimal and secure routing decisions. FAST uses prior global knowledge of real-time vehicular traffic for packet routing from the source to the destination. In FAST, fuzzy inference system leverages friendship mechanism to make critical decisions at intersections which is based on prior global knowledge of real-time vehicular traffic information. The simulation results in urban vehicular environment for with and without obstacles scenario show that the FAST performs best in terms of packet delivery ratio with upto 32% increase, average delay 80% decrease, and hops count 50% decrease compared to the state of the art VANET routing solutions.
Analysis-Sensitive Conversion of Administrative Data into Statistical Information Systems (2012)

This chapter presents a case study concerning the development of a Statistical Information System (SIS) out of data coming from administrative archives of the PAs. Such archives are a rich source of up to date information, but an attempt to use them as sources for statistical analysis reveals errors and incompatibilities among each other that do not permit their usage as a statistical and decision support basis. These errors and incompatibilities are usually undetected during administrative use, since they do not affect their day-by-day use in the PAs; however they need to be fixed before performing any further aggregate analysis. The reader is engaged with the basic aspects involved in building a SIS out of administrative data, such as design of an integration model for different and heterogeneous data sources, improvement of the overall data quality, removal of errors that might impact on the correctness of statistical analysis, design of a data warehouse for statistical analysis, and design of a multidimensional database to develop indicators for decision support. Finally, some examples are presented concerning the information that can be obtained by making use of a SIS constructed out of Registry and Income Office archives.
Selected Technical and Perceptual Aspects of Virtual Reality Displays (2006)

Volatile organic compounds (VOCs) are perceived as serious pollutants due to their great threat to both environment and human health. Recovery and removal of VOCs is of great significance. Herein, novel MOF-199 derived porous carbon materials (MC-T-n) were prepared by using MOF-199 as precursor, glucose as additional carbon source and KOH as activator, and then characterized. Adsorption performance of MC-T-n materials for benzene vapor was investigated. Isotherms of MC-T-n samples towards benzene and water vapor were measured. The adsorption selectivities of benzene/water were estimated by DIH (difference of the isosteric heats) equation. Results indicated that BET surface area and pore volume of MC-T-n materials reached separately 2320 m<sup>2</sup>/g and 1.05 m<sup>3</sup>/g. Benzene adsorption capacity of MC-T-n materials reached as high as 12.8 mmol/g at 25 °C, outperforming MOF-199 and some conventional adsorbents. Moreover, MC-T-n materials presented type-V isotherms of water vapor, suggesting their excellent water resistance. The isosteric heats of benzene adsorption on MC-500-6 were much greater than that of water adsorption, leading to a preferential adsorption for C<sub>6</sub>H<sub>6</sub> over H<sub>2</sub>O. The adsorption selectivity of C<sub>6</sub>H<sub>6</sub>/H<sub>2</sub>O on MC-500-6 reached up to 16.3 superior to some previously reported MOFs. Therefore, MC-500-6 was a promising candidate for VOC adsorption and seperation. This study provides a strong foundation for MOF derived porous carbons as adsorbents for VOC removal.
Ultrawideband ultralow PDN impedance of decoupling capacitor embedded interposers using narrow gap chip parts mounting technology for 3-D integrated LSI system (2014)

We have developed a new chip capacitor embedded interposer using a narrow gap chip parts mounting technology. This interposer is expected to reduce power distribution network (PDN) impedance. To investigate the efficacy of the interposer, we have fabricated other various types of capacitor embedded interposer test element group (TEG), such as a general chip capacitor embedded organic interposer, a thin film capacitor on a silicon interposer using the same design. We evaluated PDN impedances of decoupling capacitor embedded interposers for a 3-D integrated LSI system by using a developed ultralow impedance evaluation system. As a result, the chip capacitor embedded interposer using the narrow gap chip parts mounting technology shows a low PDN impedance below 0.1 Ω could be evaluated at the frequency range of up to 10 GHz. This indicates that the developed interposer shows a comparable level of the PDN impedance as the thin film capacitor embedded silicon interposer. It can be realized that the PDN impedance of the interposer shows below 1/100 compared with a general interposer with embedded the chip capacitor parts of 0603 types.

Non-zero sum games and survivable malware (2004)

There has been much recent work in the area of beneficial mobile agents and malicious mobile agents such as cryptoviruses. We show that by making a cryptovirus a distributed algorithm, and by utilizing PKI, mix-nets, and public bulletin boards, novel malware attacks are possible. In particular, a distributed cryptovirus attack is presented that forces the victim to become a player in a nonzero sum game under the threat of sensitive information disclosure. The attack is modeled as a nonzero sum game wherein the rules are enforced by cryptographic protocols. It is shown that the optimal strategy for the host machine involves the extension of the life of the payload even after it is discovered on the victim's machine. This therefore extends both the life and decision capability of the virus. The existence of this attack demonstrates the plausibility of survivable malware in public networks.
Comparison of Pooling 11 or 5 Oropharyngeal Swabbings for Detecting Avian Influenza Virus by Real-Time Reverse Transcription–PCR in Broiler Chickens (2012)

The effect of pooling 11 or 5 oropharyngeal (O/P) swabbings on detecting avian influenza virus (AIV) by real-time reverse transcription (RRT)-PCR was evaluated. The model used for the evaluation was designed to minimize viral load and, thus, assess the effect of the pooling on detection. Two-week-old broiler chickens were inoculated via the intranasal route with the low pathogenicity chicken/Maryland/Minh Ma/04 H7N2 strain or remained uninoculated. On days 2, 3, 4, 5, 7, 9, 11, and 14 postinoculation (PI), O/P swabbings were collected from individual infected birds and pooled with either 10 or 4 O/P swabs from uninfected broilers to produce 10 replicate pools of 11 or 5 swabbings, respectively. AIV was readily detected (80%-100%) by RRT-PCR in the pools of 11 and pools of 5 swabbings from days 2 through 5 PI. Detection in pools of both types decreased to similar levels on day 7 (40% for the pools of 11 and 50% for the pools of 5). AIV was not detected on day 9, 11, and 14 PI in pools of either size. On a given sample day PI, mean cycle threshold (Ct) values were consistently higher (lower genome levels) in the pools of 11 compared to the pools of 5. These differences were statistically significant on days 3 and 5 PI, yet Ct values associated with both types of pools were clearly interpretable as AIV positive.
n-3 Polyunsaturated Fatty Acids Suppress Mitochondrial Translocation to the Immunologic Synapse and Modulate Calcium Signaling in T Cells (2010)

Recent studies indicate that the process of Ag presentation induces cytoskeleton-dependent mitochondrial redistribution to the immediate vicinity of the immunologic synapse (IS). This redistribution of mitochondria to the IS in T cells is necessary to maintain Ca(2+) influx and Th cell activation. Recently, we demonstrated that n-3 polyunsaturated fatty acids (PUFAs) suppress the localization and activation of signaling proteins at the IS. Therefore, we hypothesized that n-3 PUFAs suppress CD4(+) T cell mitochondrial translocation during the early stages of IS formation and downmodulate Ca(2+)-dependent Th cell activation. CD4(+) cells derived from fat-1 mice, a transgenic model that synthesizes n-3 PUFA from n-6 PUFA, were cocultured with anti-CD3-expressing hybridoma cells (145-2C11) for 15 min at 37 degrees C, and mitochondrial translocation to the IS was assessed by confocal microscopy. Fat-1 mice exhibited a significantly (p < 0.05) reduced percentage of T cells with mitochondria which translocated to the IS; fat-1 (30%) versus wild type control (82%). Regarding the effect on the mitochondrial-to-cytosolic Ca(2+) ratio, wild type cells showed significant increases at the IS (71%) and total cell (60%) within 30 min of IS formation. In contrast, fat-1 CD4(+) T cells remained at basal levels following the IS formation. A similar blunting of the mitochondrial-to-cytosolic Ca(2+) ratio was observed in wild type cells that were coincubated with inhibitors of the mitochondrial uniporter, RU360 or calcium release-activated Ca(2+) (CRAC) channels, BTP2. These observations provide evidence that n-3 PUFAs modulate Th cell activation by limiting mitochondrial translocation to the IS and reducing Ca(2+) entry.

Development of bio-based polymers for use in asphalt. (2014)

Asphalt binder is typically modified with poly type (styrene-butadiene-styrene or SBS) polymers to improve its rheological properties and performance grade. The elastic and principal component of SBS polymers is butadiene. For the last decade, butadiene prices have fluctuated and significantly increased, leading state highway agencies to search for economically viable alternatives to butadiene based materials. This project reports the recent advances in polymerization techniques that have enabled the synthesis of elastomeric, thermoplastic, block-copolymers (BCPs) comprised of styrene and soybean oil, where the “B” block in SBS polymers is replaced with polymerized triglycerides derived from soybean oil. These new breeds of biopolymers have elastomeric properties comparable to well-established butadiene-based styrenic BCPs. In this report, two types of biopolymer formulations are evaluated for their ability to modify asphalt binder. Laboratory blends of asphalt modified with the biopolymers are tested for their rheological properties and performance grade. Blends of asphalt modified with the biopolymers are compared to blends of asphalt modified with two commonly used commercial polymers. The viscoelastic properties of the blends show that biopolymers improve the performance grade of the asphalt to a similar and even greater extent as the commercial SBS polymers. Results shown in this report indicate there is an excellent potential for the future of these biopolymers as economically and environmentally favorable alternatives to their petrochemically-derived analogs.
[Surgical-technical problems of triple pelvic osteotomy. Early results of the polygonal method]. (1993)

Since the first description of the triple pelvic osteotomies papers reporting on the improvement of the operative technique were continuously published. This is explained by the more problematic details of the operation. Authors worked out to the technique of the polygonal triple pelvic osteotomy, published by Kotz, Dávid and Uyka, a new exposure that makes more simple, quick and safe the performance of the operation. The essential feature is that the os ischii is reached after the osteotomy of the trochanter major from a lateral exposure and so the field of operation can be widely surveyed. At the same time transposition can also be performed. The experiences gained in 12 operations are reported, 8 of which were made according to their own method (follow-up: 8-22 months, in average 15 months). The patients were 14-33 years old and their complaints disappeared in every case. Authors suggest the operation for the correction of the dysplastic acetabulum in young adults and also in puberty after the fusion of the Y cartilage if no subluxation exists. Minor articular deformity and mild arthrosis are not considered as a contraindication.
Association Between Physical Activity and BMD in Young Men Is Modulated by Catechol-O-Methyltransferase (COMT) Genotype: The GOOD Study (2007)

We show that the COMT val158met polymorphism modulates the association between PA, aBMD, and trabecular vBMD, suggesting that this polymorphism is of importance for BMD in subjects with a low level of PA.
Assessment of fall-risk by means of a neural network based on parameters assessed by a wearable device during posturography (2007)

We have investigated the use of an Artificial Neural Network (ANN) for the assessment of fall-risk (FR) in patients with different neural pathologies. The assessment integrates a clinical tool based on a wearable device (WD) with accelerometers (ACCs) and rate gyroscopes (GYROs) properly suited to identify trunk kinematic parameters that can be measured during a posturography test with different constraints. Our ANN--a Multi Layer Perceptron Neural Network with four layers and 272 neurones--shows to be able to classify patients in three well-known fall-risk levels. The training of the neural network was carried on three groups of 30 subjects with different Fall-Risk Tinetti scores. The validation of our neural network was carried out on three groups of 100 subjects with different Fall-Risk Tinetti scores and this validation demonstrated that the neural network had high specificity (> or =0.88); sensitivity (> or =0.87); area under Receiver-Operator Characteristic Curves (>0.854).
