Differential chemosensitivity in oncogene-transformed cells. (1996)

The effects of anticancer drugs on cell growth have been investigated by MTT colorimetric assay using mouse and rat cultured cells transformed by various oncogenes and tumor viruses. Aclarubicin, mitomycin C and 1-hexylcarbamoyl-5-fluorouracil showed higher growth-inhibitory activities toward transformed cells than those toward the normal counterparts. Nimustine, bleomycin and 5-fluorouracil also showed selective growth-suppressive activities toward transformed cells except for a few cell lines. ras-oncogene-transformed cells were more sensitive toward 5-fluorouracil and 1-hexylcarbamoyl-5-fluorouracil than the normal parent cells and other transformed cells. These drugs would thus be effective in the chemotherapy of ras-induced cancer.
Exploring Failure of Total Shoulder Arthroplasty Systems Through Implant Retrieval, Radiographic, and Clinical Data Analyses (2017)

Background Retrieved clinically failed anatomic total shoulder arthroplasty (TSA) components as well as associated radiographs and medical records were analyzed in order to investigate the origins of clinical failure(s) of TSA components. Methods Fifty TSA systems were retrieved from 48 patients including 27 females and 21 males; components were implanted for an average of 68 months (range, 2–267). Data obtained through radiographic analysis, medical records review, and damage mode analysis of each component were performed and statistically analyzed. Results Significant correlations were found between glenoid loosening and preoperative pain ( r = 1.00, P &lt; .001), humeral stem scratching and humeral loosening (Zone 1: r = .60, P &lt; .01; Zone 2: r = .45, P = .03; Zone 3: r = .45, P = .03) , as well as glenoid damage and rotator cuff tears ( r = .36, P = .02). Discussion Wear and damage of the glenoid and humeral components, which may result from rotator cuff tearing, may lead to accelerated loosening, clinical failure, and early revision arthroplasty. Improved implant design and/or surgical indications may improve implant performance, thereby reducing the incidence of implant damage and wear, and result in improved clinical outcomes.
Plaque area at carotid and common femoral bifurcations and prevalence of clinical cardiovascular disease. (2010)

Total plaque area appears to be more strongly associated with the prevalence of cardiovascular disease than IMT. This finding warrants further prospective studies.
Hypothyroidism and the Risk of Venous Thromboembolism: A Nationwide Cohort Study (2020)

The data suggest that hypothyroidism was significantly associated with an increased risk of VTE. Among hypothyroid patients, a non-significant trend of lower VTE risk in patients treated with TRT was observed. Further prospective studies or clinical trials are necessary to confirm causality.

Accessing relational databases from the World Wide Web (1996)

With the growing popularity of the internet and the World Wide Web (Web), there is a fast growing demand for access to database management systems (DBMS) from the Web. We describe here techniques that we invented to bridge the gap between HTML, the standard markup language of the Web, and SQL, the standard query language used to access relational DBMS. We propose a flexible general purpose variable substitution mechanism that provides cross-language variable substitution between HTML input and SQL query strings as well as between SQL result rows and HTML output thus enabling the application developer to use the full capabilities of HTML for creation of query forms and reports, and SQL for queries and updates. The cross-language variable substitution mechanism has been used in the design and implementation of a system called DB2 WWW Connection that enables quick and easy construction of applications that access relational DBMS data from the Web. An end user of these DB2 WWW applications sees only the forms for his or her requests and resulting reports. A user fills out the forms, points and clicks to navigate the forms and to access the database as determined by the application.
Classical Thermodynamic Analysis of D-Based Nuclear Fusion Reactions: The Role of Entropy (2023)

In this work, the feasibility of nuclear processes is studied via classical thermodynamics by assessing the change in entropy, a parameter that has so far been neglected in the analysis of these reactions. The contribution of the entropy to the reaction spontaneity plays a different role in the fission and fusion reactions. In particular, in fusion reactions the temperature acts as a very powerful amplifier of the entropic term (−T ΔS) that, at the temperature of tokamaks (millions Kelvin), may significantly reduce the thermodynamic spontaneity of these processes. A new approach is followed for assessing the feasibility of the D-based reactions of interest for the magnetically confined nuclear fusion through the investigation of the effect of the temperature on both kinetics and thermodynamics. The results confirm that the deuterium–tritium reaction is the most promising fusion reaction to be realized in tokamak devices. At the temperature of 1.5 × 108 K (≈13 keV), the DT reaction exhibits a large thermodynamic spontaneity (ΔG = 16.0 MeV) and its reactivity is of the order of 10−22 m3/s, a value capable of guaranteeing the tritium burning rate needed to operate the nuclear plants under tritium self-sufficiency conditions and with a net energy production. The other results show that at the tokamaks’ temperature the two branches of the DD reaction exhibit a modest spontaneity (ΔG around −2 MeV) coupled to very low reactivity values (10−24 m3/s). The temperature rise that could be aimed to increase the reactivity is however ineffective to improve the reaction feasibility since it would augment the entropic term as well, thus shifting the ΔG towards positive values. The D3He reaction is soundly spontaneous at the tokamaks’ temperature (ΔG values of −17.2 MeV) while its kinetics is close to that of the DD reactions, which are at least two orders of magnitude lower than that of the DT reaction.
Comparing Neural and Attractiveness-based Visual Features for Artwork Recommendation (2017)

Advances in image processing and computer vision in the latest years have brought about the use of visual features in artwork recommendation. Recent works have shown that visual features obtained from pre-trained deep neural networks (DNNs) perform extremely well for recommending digital art. Other recent works have shown that explicit visual features (EVF) based on attractiveness can perform well in preference prediction tasks, but no previous work has compared DNN features versus specific attractiveness-based visual features (e.g. brightness, texture) in terms of recommendation performance. In this work, we study and compare the performance of DNN and EVF features for the purpose of physical artwork recommendation using transactional data from UGallery, an online store of physical paintings. In addition, we perform an exploratory analysis to understand if DNN embedded features have some relation with certain EVF. Our results show that DNN features outperform EVF, that certain EVF features are more suited for physical artwork recommendation and, finally, we show evidence that certain neurons in the DNN might be partially encoding visual features such as brightness, providing an opportunity for explaining recommendations based on visual neural models.
Abnormal grain growth in a Zn-0.8Ag alloy after processing by high-pressure torsion (2021)

Abnormal grain growth (AGG) in a Zn-0.8Ag (wt%) alloy, produced through the application of high-pressure torsion (HPT), was systematically investigated using scanning electron microscopy (SEM), electron backscattered diffraction (EBSD), high-resolution transmission electron microscopy (HR-TEM) and microhardness testing. The HPT-deformed alloy exhibits AGG at room temperature without any additional heat treatment. Analysis by EBSD revealed oriented grain nucleation in a {112¯0}〈0001〉 direction from the initial (0001) fibre texture which agrees with the maximum energy release model. New grains were oriented according to the minimal Young's modulus direction (c-axis), parallel to the shearing direction. The strain-induced dissolution of nanocrystalline Zn3Ag precipitates was identified as the main driving force for AGG in this alloy. The strains necessary for the initiation and termination of AGG were determined as ~4.0 and ~5.0, respectively. The increase in solid-solution strengthening caused an increase in hardness from ~47 HK in the fine-grained centre to ~84 HK in the coarse-grained region. A Hall-Petch investigation revealed grain refinement softening below a grain size of 23 µm. These results provide the first comprehensive description of AGG in metallic materials processed by a severe plastic deformation method at room temperature.
A Method for Determination of Damping for Edgewise Blade Vibrations (2000)

Abstract Violent edgewise blade vibrations have in recent years been a large problem for some stall‐regulated wind turbines. Owing to the complexity of the phenomenon, it has been difficult to predict the risk of these vibrations with aeroelastic load prediction tools. One problem is the choice of parameters in the aeroelastic model, e.g. structural damping and aerodynamic aerofoil characteristics. In many cases a high degree of uncertainty in the predicted response exists and the need for experimental verification methods is obvious. In this work a new method to identify the effective damping for the edgewise blade mode shape for wind turbines has been developed. The method consists of an exciter mechanism which makes it possible to excite the edgewise blade mode shapes from the wind turbine nacelle. Furthermore, the method consists of an analysis method which enables a straightforward determination of the damping. The analysis method is based on a local blade whirl description of the edgewise blade vibrations. The method is verified on a Bonus wind turbine, and for this specific turbine the effective damping for edgewise blade vibrations has been determined. The results support the further development of aeroelastic models and show potential for fine‐tuning of parameters of importance for the edgewise blade vibration problem. Furthermore, the method can be used for experimental investigation of the risk of edgewise blade vibrations for a specific turbine. Copyright © 2000 John Wiley &amp; Sons, Ltd.
Aqueous dispersion of hexagonal boron nitride via plasma processing in a hydroquinone solution (2020)

Abstract Plasma processing in a solution with a hydroquinone additive was performed for the aqueous dispersion of hexagonal boron nitride (h-BN), and the effect of the hydroquinone additive was determined by analyzing the zeta potential distribution. The hydroquinone additive enhanced plasma modification in the solution to produce well-dispersed h-BN particles separated by centrifugation. The mean zeta potential improved up to −50 mV at neutrality and maintained in a pH range of 6–9. Infrared absorption spectra suggested that the dispersed h-BN particles were modified with hydroxyl functional groups by plasmas in the solution.
Safety and Immunogenicity of a Five-Dose Series of Inactivated Mycobacterium vaccae Vaccination for the Prevention of HIV-Associated Tuberculosis (2000)

Five doses of inactivated Mycobacterium vaccae vaccine were administered intradermally to 22 human immunodeficiency virus (HIV)-infected patients (11 bacille Calmette-Guérin [BCG]-positive and 11 BCG-negative) in Zambia whose CD4 lymphocyte counts were >/=200 cells/mm(3). HIV viral load and lymphocyte proliferation responses were compared for vaccine recipients and 22 HIV-infected control patients (11 BCG-positive and 11 BCG-negative). Immunization was safe and well tolerated in all patients, and induration at the vaccine site decreased from dose 1 to dose 5. A transient decrease in HIV viral load was observed in BCG-positive vaccine recipients after dose 3 but not after subsequent doses. Median lymphocyte stimulation indices to M. vaccae were 6.0 in vaccine recipients and 2.3 in control patients (P<.001). Stimulation indices were >/=3.0 in 19 vaccine recipients (86%) and 7 control patients (32%; P=.001). A 5-dose series of vaccination with inactivated M. vaccae is safe in HIV-infected patients and induces lymphocyte proliferation responses to the vaccine antigen. M. vaccae vaccine is a candidate for the prevention of tuberculosis in HIV infection.
Whitening Effect of Salicylic Acid Peels in Asian Patients (2006)

BACKGROUND Patients with skin of color demand treatment modality suitable for their skin. Salicylic acid peel has effectiveness for both of acne and postinflammatory hyperpigmentation that are common in patients with skin of color. OBJECTIVE To assess the whitening effect of salicylic acid peels in Asian patients with acne objectively by the colorimetric method. METHODS Twenty-four healthy adult patients with acne participated voluntarily in the study. Any other systemic and topical acne treatments were prohibited. They had undergone full-face peels with 30% salicylic acid in absolute ethanol bi-weekly for 3 months. Colorimetric changes of the face were recorded with reflectance spectrophotometer. RESULTS Paired comparisons with pretreatment CIE L*a*b* showed abrupt descent of L* value after first peel (p=.0286). Then there was continued increase of mean L* value, even though the final L* value did not reach a statistically significant level. The mean a* value decreased continually, and the a* values recorded after the second, third, fourth, fifth, and final peel showed significantly lowered levels (p=.0027, .0005, <.0001, <.0001, <.0001). CONCLUSION Salicylic acid peels are beneficial in whitening the face of Asian patients with acne. The whitening effect would be an important factor in choosing the superficial peeling agent for them.
5.1: A Wide‐View Novel Design for Stereoscopic 3D LCD (2012)

Abstract In this paper we used a rigorous optical model to investigate the viewing angle properties of patterned retarder (PR) stereoscopic 3D liquid crystal display (LCD). By analyzing the simulation and experiment of passive glasses and PR structure, we suggested several new design structures to enlarge the viewing angle at oblique and horizontal direction. Compare to conventional structure and several new structures [1] [2], our new designs had several advanced features, such as simple structure, low cost, easy to realize and of course wide viewing angle.
The effect of the inner-hair-cell mediated transduction on the shape of neural tuning curves (2018)

The inner hair cells of the mammalian cochlea transform the vibrations of their stereocilia into releases of neurotransmitter at the ribbon synapses, thereby controlling the activity of the afferent auditory fibers. The mechanical-to-neural transduction is a highly nonlinear process and it introduces differences between the frequency-tuning of the stereocilia and that of the afferent fibers. Using a computational model of the inner hair cell that is based on in vitro data, we estimated that smaller vibrations of the stereocilia are necessary to drive the afferent fibers above threshold at low (≤0.5 kHz) than at high (≥4 kHz) driving frequencies. In the base of the cochlea, the transduction process affects the low-frequency tails of neural tuning curves. In particular, it introduces differences between the frequency-tuning of the stereocilia and that of the auditory fibers resembling those between basilar membrane velocity and auditory fibers tuning curves in the chinchilla base. For units with a characteristic frequency between 1 and 4 kHz, the transduction process yields shallower neural than stereocilia tuning curves as the characteristic frequency decreases. This study proposes that transduction contributes to the progressive broadening of neural tuning curves from the base to the apex.

Dynamic single frequency networks (2001)

Wireless asymmetric Internet access with a downlink peak bit rate of 10 to 30 Mb/s can be achieved by using the terrestrial digital video broadcasting system (DVB-T) as a supplemental downlink together with today's cellular systems. This paper is a study of dynamic radio resource management on a packet-by-packet basis for this broadband downlink. The dynamic single frequency networks (DSFN) scheme is evaluated. It exploits the macrodiversity capability of the OFDM modulation scheme. The transmitters are dynamically divided into groups of transmitters that send the same information at the same channel frequency simultaneously. The fairly shared spectrum efficiency (FSSE), in bits per second per Hertz per site, which is a combined measurement of maximum throughput and fairness, is evaluated for best-effort traffic. DSFN improves the FSSE by 100% to 370%, for a certain set of test cases, in comparison to the dynamic packet assignment (DPA) scheme, which combines packet scheduling with dynamic channel assignment (DCA).
DIRECT MEASUREMENTS OF SURFACE STRESS USING TRANSMISSION ELECTRON MICROSCOPY (1997)

Surface stress and energy are concepts which are often misunderstood. In this work, we will clarify the difference between the two. We describe the use of transmission electron microscopy to measure surface stress by quantitative analysis of strain contrast images. We find that images of surface-stress-induced strain fields can be used to measure quantitative differences in surface stress provided the imaging parameters are accurately determined. We have applied this method to measure the stress difference between the 7×7 and high temperature "1×1" phases of the Si(111) surface at the phase coexistence temperature and between metastable phase boundaries on the Si(111) and amorphous-Ge interface. We discuss the significance of these measurements and pitfalls to be avoided in image simulations.
Sequence‐tagged high‐density genetic maps of Zoysia japonica provide insights into genome evolution in Chloridoideae (2015)

Zoysiagrass (Zoysia spp.), belonging to the genus Zoysia in the subfamily Chloridoideae, is widely used in domestic lawns, sports fields and as forage. We constructed high-density genetic maps of Zoysia japonica using a restriction site-associated DNA sequencing (RAD-Seq) approach and an F1 mapping population derived from a cross between 'Carrizo' and 'El Toro'. Two linkage maps were constructed, one for each of the parents. A map consisting of 2408 RAD markers distributed on 21 linkage groups was constructed for 'Carrizo'. Another map with 1230 RAD markers mapped on 20 linkage groups was constructed for 'El Toro'. The average distance between adjacent markers of the two maps was at 0.56 and 1.4 cM, respectively. Comparative genomics analysis was carried out among zoysiagrass, rice and sorghum genomes and a highly conserved collinearity in the gene order was observed among the three genomes. Chromosome collinearity was disrupted at centromeric regions for each chromosome pair between zoysiagrass and sorghum genomes. However, no obvious synteny gaps were observed across the centromeric regions between zoysiagrass and rice genomes. Two homologous chromosomes for each of the 10 sorghum chromosomes were found in the zoysiagrass genome, indicating an allotetraploid origin for zoysiagrass. The reduction of the basic chromosome number from 12 to 10 in chloridoids and panicoids took place via independent single-step nested chromosome fusion events after the two subfamilies diverged from a common ancestor. The genetic maps will assist in genome sequence assembly, targeted gene isolation and comparative genomic analyses among grasses.
Data Bus Inversion in High-Speed Memory Applications (2009)

Efforts to reduce high-speed memory interface power have led to the adoption of data bus inversion or bus-invert coding. This study compares two popular algorithms, which seek to limit the number of simultaneously transitioning signals and bias the state of transmitted data toward a preferred binary level, respectively. A new algorithm, which provides a compromise between transition frequency and preferred signal level, is proposed, and the three algorithms are compared in terms of their impact on power consumption, power supply noise reduction, and general signal integrity enhancement when used in conjunction with a variety of link topologies.
