Leaky Lamb waves in fibrous composite laminates (1985)

Results of experimental measurements and theoretical calculations on ultrasonic leaky Lamb-wave propagation in fiber-reinforced, unidirectional composite laminates are presented. With the Lamb wave vector oriented parallel to the fiber direction, dispersion curves of phase velocity versus frequency and plate thickness have been constructed from measurements of ultrasonic reflection from fluid-loaded composite plates. The experimental results are supported by a theoretical model of Lamb-wave propagation in the composite plate. The model begins with an approximate calculation of the effective, homogeneous, transversely isotropic elastic behavior of a unidirectional composite laminate in the long-wavelength limit, using a two-step procedure based on alternating layered media. This intermediate continuum result is then incorporated into a calculation of the ultrasonic reflection coefficient of a fluid-loaded anisotropic plate, which is assumed to approximate the fibrous composite laminate. Good quantitative agreement with the model is found if the fiber volume fraction is taken to be an adjustable parameter. However, not all portions of the dispersion curves predicted by the model can be observed in the data. It is conjectured that relative differences in mode coupling account for this discrepancy.
DR3 stimulation of adipose resident ILC2s ameliorates type 2 diabetes mellitus (2020)

Disturbances in glucose homeostasis and low-grade chronic inflammation culminate into metabolic syndrome that increase the risk for the development of type 2 diabetes mellitus (T2DM). The recently discovered group 2 innate lymphoid cells (ILC2s) are capable of secreting copious amounts of type 2 cytokines to modulate metabolic homeostasis in adipose tissue. In this study, we have established that expression of Death Receptor 3 (DR3), a member of the TNF superfamily, on visceral adipose tissue (VAT)-derived murine and peripheral blood human ILC2s is inducible by IL-33. We demonstrate that DR3 engages the canonical and/or non-canonical NF-κB pathways, and thus stimulates naïve and co-stimulates IL-33-activated ILC2s. Importantly, DR3 engagement on ILC2s significantly ameliorates glucose tolerance, protects against insulin-resistance onset and remarkably reverses already established insulin-resistance. Taken together, these results convey the potent role of DR3 as an ILC2 regulator and introduce DR3 agonistic treatment as a novel therapeutic avenue for treating T2DM.
Structural diversity in social contagion (2012)

The concept of contagion has steadily expanded from its original grounding in epidemic disease to describe a vast array of processes that spread across networks, notably social phenomena such as fads, political opinions, the adoption of new technologies, and financial decisions. Traditional models of social contagion have been based on physical analogies with biological contagion, in which the probability that an individual is affected by the contagion grows monotonically with the size of his or her "contact neighborhood"--the number of affected individuals with whom he or she is in contact. Whereas this contact neighborhood hypothesis has formed the underpinning of essentially all current models, it has been challenging to evaluate it due to the difficulty in obtaining detailed data on individual network neighborhoods during the course of a large-scale contagion process. Here we study this question by analyzing the growth of Facebook, a rare example of a social process with genuinely global adoption. We find that the probability of contagion is tightly controlled by the number of connected components in an individual's contact neighborhood, rather than by the actual size of the neighborhood. Surprisingly, once this "structural diversity" is controlled for, the size of the contact neighborhood is in fact generally a negative predictor of contagion. More broadly, our analysis shows how data at the size and resolution of the Facebook network make possible the identification of subtle structural signals that go undetected at smaller scales yet hold pivotal predictive roles for the outcomes of social processes.
Narrow linewidth tunable DBR lasers (2016)

Thermally tuned sampled-grating distributed Bragg reflector lasers achieve 50dB side-mode-suppression ratio, and >17dBm fiber-coupled output power over the full C-band to meet the demands of flex-grid wavelength-division-multiplexed coherent transmission systems.
Biomechanical Assessment of Flexible Flatfoot Correction (2014)

An understanding of treatment effectiveness is essential for optimizing operative management of symptomatic flatfoot deformity. This study provides empirical evidence of the advantage of lateral column lengthening and novel information on resistance to postoperative loss of correction.
Influence and adjustment of carrier lifetimes in InGaAs/InAlAs photoconductive pulsed terahertz detectors: 6 THz bandwidth and 90dB dynamic range (2014)

We investigate the influence of Beryllium (Be) doping on the performance of photoconductive THz detectors based on molecular beam epitaxy (MBE) of low temperature (LT) grown In(0.53)Ga(0.47)As/In(0.52)Al(0.48)As multilayer heterostructures (MLHS). We show how the optical excitation power affects carrier lifetime, detector signal, dynamic range and bandwidth in THz time domain spectroscopy (TDS) in dependence on Be-doping concentration. For optimal doping we measured a THz bandwidth in excess of 6 THz and a dynamic range of up to 90 dB.
Low-Stress CMOS-Compatible Silicon Carbide Surface-Micromachining Technology—Part II: Beam Resonators for MEMS Above IC (2011)

Microelectromechanical beam resonators and arrays are fabricated using a custom low-temperature complementary-metal-oxide-semiconductor-compatible silicon carbide microfabrication process, detailed in Part I of this paper. Theoretical aspects are presented with modal analysis and numerical methods. Measurements of the resonant frequency, the quality factor, the transmission, and the tuning characteristics are presented for different device types and dimensions. Trends are analyzed, and performance metrics dependences are investigated. A tuning method based on integrated heaters is introduced and tested, yielding a very desirable constant insertion-loss tuning and a wide tuning range. Quality factors of up to 1493 and resonant frequencies of up to 26.2 MHz are demonstrated. Both the Young's modulus and the residual stress of the SiC film are extracted (261 GPa and <; ±30 MPa, respectively), and favorably compare to values reported for polysilicon.
Whole-genome phylogeny of<i>Escherichia coli</i>/<i>Shigella</i>group by feature frequency profiles (FFPs) (2011)

A whole-genome phylogeny of the Escherichia coli/Shigella group was constructed by using the feature frequency profile (FFP) method. This alignment-free approach uses the frequencies of l-mer features of whole genomes to infer phylogenic distances. We present two phylogenies that accentuate different aspects of E. coli/Shigella genomic evolution: (i) one based on the compositions of all possible features of length l = 24 (∼8.4 million features), which are likely to reveal the phenetic grouping and relationship among the organisms and (ii) the other based on the compositions of core features with low frequency and low variability (∼0.56 million features), which account for ∼69% of all commonly shared features among 38 taxa examined and are likely to have genome-wide lineal evolutionary signal. Shigella appears as a single clade when all possible features are used without filtering of noncore features. However, results using core features show that Shigella consists of at least two distantly related subclades, implying that the subclades evolved into a single clade because of a high degree of convergence influenced by mobile genetic elements and niche adaptation. In both FFP trees, the basal group of the E. coli/Shigella phylogeny is the B2 phylogroup, which contains primarily uropathogenic strains, suggesting that the E. coli/Shigella ancestor was likely a facultative or opportunistic pathogen. The extant commensal strains diverged relatively late and appear to be the result of reductive evolution of genomes. We also identify clade distinguishing features and their associated genomic regions within each phylogroup. Such features may provide useful information for understanding evolution of the groups and for quick diagnostic identification of each phylogroup.
Practices of prescribing oral contraceptives in Poland (2001)

We developed and performed a survey on practices of prescribing oral contraceptives in Poland. The survey was carried out in Warsaw, the capital city of Poland and one of the most important areas of the country (approximately 4 million inhabitants). The main aim of the study was to recognize the rationale and practices of prescribing oral contraceptives by gynecologists in Poland (oral contraceptives are prescribed mostly by gynecologists, not by general practitioners or midwives). The questions were sent to all members of Warsaw's Association of Gynecologists, but we have received back only 276 answers (79% of the total number of members) and the responses are presented here. The responses revealed that the most popular oral contraceptives are those modern formulations combining low doses of ethinylestradiol and progestogens such as norgestimate, desogestrel, gestodene and levonorgestrel. For gynecologists, the most important factors in the selection of an oral contraceptive were the dose of hormones (20.3%), the formulation (18.5%), tolerance by patients (23.5%) and past clinical experience with the formulation (9.4%). The price was most important for 3.7%, and good marketing practices were most important for 8.3% of the gynecologists.
Estimating Software Energy Consumption with Machine Learning Approach by Software Performance Feature (2018)

With the growing scale of the application and ability to compute, more and more people pay attention to software energy consumption. There is a huge potential for controlling energy consumption during the application's development phase. Although the energy consumption of software can be obtained by tools or models, the problem of how energy consumption is consumed is still not explained. To solve this problem, a model of energy consumption characterized by performance events is established with using the method of ridge regression machine learning, which can explain the origin of energy consumption, and the error rate is only 6.8%. Our model is based on performance events from perf tool and is independent of the application scenario. Using this model, it does not require programmers to measure and train their own applications, it can also decrypt the causes of energy consumption.
Evidence for layered growth of (100) textured diamond films (1997)

The growth of diamond films synthesized by the hot filament chemical vapor deposition method has been studied by scanning tunneling microscopy (STM). The smooth (100) faces of micron-sized diamond crystallites were found to exhibit pyramidal shaped architecture at the nano level. The STM data for chemical vapor deposited diamond is analyzed in the light of recently developed dynamical scaling approach. The value of the scaling exponent α≅0.85 signifies a growth primarily driven by the transport of reacting species on the surface rather than molecular diffusion in gas phase.
A Single-Trace Cycle Collection for Reference Counting Systems (2009)

The lack of collecting cyclic garbage is generally considered the major weakness of reference counting. Reference counted systems handle this problem by incorporating either a global tracing collector or a partial tracing collector that considers only the cycle candidates. The latter has become a preferred one as it has better scalability and locality. Most of the partial tracing collectors are based on a classical tracing scheme, called trial deletion, which needs several traces over objects and thus may impose more overhead on tracing. Though lots of works have focused on reducing unnecessary candidates for tracing, few studies resort to the cycle collection procedure. This paper presents a novel cycle collection algorithm which can detect garbage cycles in a single trace over cycle candidates. The algorithm and the correctness proof are described in detail.
Thermal conductivity measurements of thin silicon dioxide films in integrated circuits (1996)

The thermal conductivity of thin silicon dioxide (SiO/sub 2/) films is measured using specialized test structures. The test structures consist of parallel plate-electrodes that sandwich the dielectric whose thermal conductivity is determined. The accuracy of the measurement technique is verified based on simulations. Films with thicknesses in the range of 0.57 /spl mu/m to 2.28 /spl mu/m are investigated. At room temperature the thin films exhibit a thermal conductivity of /spl sim/1.1 W/Km which is approximately 20% below that of bulk fused SiO/sub 2/. As opposed to prior studies, the thermal conductivity of the thin films is observed to increase with rising temperature. Temperature dependence of thermal conductivity is found to be very similar to that of bulk fused SiO/sub 2/. The impart of thermal resistances at boundaries between silicon dioxide and metallization is shown to be insignificant for the films investigated. In addition, no dependence of thermal conductivity on film thickness is observed. Vias are found to be very effective in reducing thermal resistance between adjacent metallization layers.
Hemagglutination of Human Type O Erythrocytes, Hemolysin Production, and Serogrouping of <i>Escherichia coli</i> Isolates from Patients with Acute Pyelonephritis, Cystitis, and Asymptomatic Bacteriuria (1981)

The purpose of this investigation was to study potential virulence factors associated with Escherichia coli urinary pathogens isolated from patients with urinary tract infection. These factors were compared with characteristics of normal-flora E. coli isolated from stool specimens of healthy individuals without a history of urinary tract infection. The potential virulence factor focused on in this study was hemagglutination (HA) of human type O erythrocytes by E. coli urinary pathogens. A total of 265 strains of E. coli isolated from patients with urinary tract infections were tested for their ability to hemagglutinate human type O erythrocytes; of these, 148 (56%) were HA positive. Only 6 of 36 fecal E. coli strains (17%) isolated from healthy controls were HA positive. This significant association of the presence of hemagglutinin on E. coli that causes urinary tract infections indicates the likelihood that HA is a marker of virulence. Only 12% (5 of 43) of Proteus mirabilis and 3% (3 of 104) of Klebsiella pneumoniae urinary isolates were HA positive. There was a trend for HA-positive E. coli to be isolated from patients with kidney infections and positive tests for antibody-coated bacteria rather than bladder infections and negative tests for antibody-coated bacteria, although the difference was not statistically significant. There was a significant correlation (P < 0.025) between hemolysin production and HA; 67% (69 of 103) of the isolates that produced hemolysin also hemagglutinated human type O erythrocytes. There was no significant correlation between HA and motility, although there was a trend for flagellated organisms to be non-hemagglutinators. There was a marked correlation between the presence of hemagglutinin and the serogroup of the E. coli isolate; serogroups O4, O7, and O50 were almost always HA positive (57 of 63; 90%). In contrast, serogroups O8 and O25 were rarely HA positive (2 of 30; 7%).
Towards Automated RESTful Web Service Composition (2009)

Emerging as the popular choice for leading Internet companies to expose internal data and resources, RESTful Web services are attracting increasing attention in the industry. While automating WSDL/SOAP based Web service composition has been extensively studied in the research community, automated RESTful Web service composition in the context of service-oriented architecture (SOA), to the best of our knowledge, is less explored. As an early paper addressing this problem, this paper discusses the challenges of composing RESTful Web services and proposes a formal model for describing individual Web services and automating the composition. It demonstrates our approach by applying it to a real-world RESTful Web service composition problem. This paper represents our initial efforts towards the problem of automated RESTful Web service composition. We are hoping that it will draw interests from the research community on Web services, and engage more researchers in this challenge.
Affecting Factors of Shooting Ability In Basketball Games: Coordination And Concentration (2023)

The shooting technique is a movement in which a player shoots the ball towards the opposing team's basketball ring. In shooting, it is necessary to have optimal physical conditions and psychological aspects. Eye-hand coordination and concentration as support to perform a series of movements when shooting. This study aims to determine the coordination and concentration shooting in basketball games for physical education students at the University of Muhammadiyah Palopo. The sample is 29 students who take class A1 basketball courses in semester 3. The results show that the correlation between hand-eye coordination and shooting ability had a significant relation of 0.000>0.05. The correlation between concentration with shooting ability is significant at 0.000>0.05. It can be concluded that coordination and concentration are strongly related to basketball shooting ability
Molecular cloning and characterization of W double-stranded RNA, a linear molecule present in Saccharomyces cerevisiae. Identification of its single-stranded RNA form as 20 S RNA (1991)

Most strains of the yeast Saccharomyces cerevisiae harbor a double-stranded RNA (dsRNA) molecule, called W. We obtained W cDNA clones by random priming of denatured W dsRNA followed by reverse transcription. Sequence data of W shows that only one strand ((+)-strand) has coding capacity for a protein with 829 amino acids which spans almost the entire length of the molecule (2.5 kilobases). Within this protein we found a sequence pattern characteristic of RNA dependent RNA polymerases of (+)-strand and double-stranded RNA viruses. W has no homology with other dsRNAs found in S. cerevisiae, such as L-A, L-BC or M1. However, a (+)-strand-specific probe for W hybridized with 20-S RNA. Furthermore, W (+)-strands comigrated with 20 S RNA in strand separation gels. These results suggest that 20 S RNA is a (+)-single-stranded RNA form of W dsRNA itself or a closely related molecule.
Detecting Music Genre Using Extreme Gradient Boosting (2018)

This paper summarizes our contribution to the CrowdAI music genre classification challenge "Learning to Recognise Musical Genre from Audio on the Web'' as part of the WebConference 2018. We utilize different approaches from the field of music analysis to predict the music genre of given mp3 music files, including a convolutional neural network for spectrogram classification, deep neural networks and ensemble methods using various numerical audio features. Our best results were obtained by an extreme gradient boosting classifier.
Designing online games for real-life relationships (2012)

Intergenerational players are online game players of different generations within an extended family. We investigated intergenerational play between older parents and their adult children in the popular Chinese social networking game QQ Farm. We identified game features that encourage intergenerational play. To do this, we conducted online observations and semi-structured interviews with nine pairs of Chinese parents and their adult children. The results of this study suggest that an online game for intergenerational play needs to consider a range of factors, including social and occupational responsibilities, gaming interests, and gaming expertise among extended family members. The data suggests that intergenerational online games may generally benefit from the following features: (1) low entry barrier, (2) appealing game theme, (3) online interactions that extend real-life relationships, (4) low time commitment, and (5) asynchronous play. We have also found features which may have unique appeal to Chinese intergenerational gamers.
Thermoplastic polyolefin roofing membranes (1999)

One of the components of a typical low-slope roofing system is the roofing membrane, the sheet that has reinforcing fibres sandwiched between sheets of flexible matrix. Its function is to waterproof the roof. The flexible matrix can be a thermoplastic polyolefin (TPO). TPO roofing membranes have numerous advantages: their seams can be heat-welded, they are resistant to heat, UV and chemicals, and they have good cold-temperature flexibility. The breaking strength of the membrane depends heavily on the number of reinforcing fibre bundles across the width of the membrane.
The importance of MUC1 cellular localization in patients with breast carcinoma (2001)

In the literature, similar findings prevailed in which overall MUC1 expression was increased in lower grade (10 of 14 studies), estrogen receptor positive (8 of 13 studies) tumors and was associated with a better prognosis (8 of 13 studies). High cytoplasmic staining was associated with a worse prognosis, an association that was not explained by differences in histologic grade. Thus, the presence of MUC1 in the majority of tumor cells is associated with better differentiated tumors and with an improved prognosis. However, aberrantly localized MUC1 in the tumor cell cytoplasm or nonapical membrane is associated with a worse prognosis.
Layer-by-Layer Dielectric Breakdown of Hexagonal Boron Nitride (2014)

Hexagonal boron nitride (BN) is widely used as a substrate and gate insulator for two-dimensional (2D) electronic devices. The studies on insulating properties and electrical reliability of BN itself, however, are quite limited. Here, we report a systematic investigation of the dielectric breakdown characteristics of BN using conductive atomic force microscopy. The electric field strength was found to be ∼ 12 MV/cm, which is comparable to that of conventional SiO2 oxides because of the covalent bonding nature of BN. After the hard dielectric breakdown, the BN fractured like a flower into equilateral triangle fragments. However, when the applied voltage was terminated precisely in the middle of the dielectric breakdown, the formation of a hole that did not penetrate to the bottom metal electrode was clearly observed. Subsequent I-V measurements of the hole indicated that the BN layer remaining in the hole was still electrically inactive. On the basis of these observations, layer-by-layer breakdown was confirmed for BN with regard to both physical fracture and electrical breakdown. Moreover, statistical analysis of the breakdown voltages using a Weibull plot suggested the anisotropic formation of defects. These results are unique to layered materials and unlike the behavior observed for conventional 3D amorphous oxides.
