High-Temperature Anelastic Relaxation of Dense Zircon Bodies (2009)

The high-temperature mechanical behavior of zircon materials may be connected with the chemical nature of the glassy phase present in these materials. Internal-friction measurements were carried out with a low-frequency pendulum, working in the 300 to 1300 K temperature range. The samples were zircon materials fabricated by sintering at 1843 K (ZI samples) and 1903 K (ZII samples). In the ZII samples, a mechanical loss peak is observed in the temperature range between 1000 and 1250 K; the peak temperature depends on the frequency of measurement. This peak is tentatively attributed to grain boundary sliding controlled by the viscosity of the glassy phase segregated in the boundary, in the temperature range of its a relaxation.
<title>Optical measurements of plastic (polyimide) hollow waveguides for IR radiation</title> (1998)

Hollow waveguides for infrared radiation are suitable for high power radiation and large interval of wavelengths. This has enabled to begin its preparation for several practical applications in medicine which are already investigated. One of the types of these waveguides is made from plastic (teflon) tubes and several papers were published in this field. Although the Teflon waveguides have several important advantages (high flexibility and biological suitability) for application in medicine, there are also difficulties in achieving low attenuation (low radiation losses), of the transmitted radiation, which is limiting their applications. One of the main reasons of the large losses of the transmitted radiation through these waveguides is the relative large roughness of the internal wall of the tubes which produce scattering of the incident radiation. Several attempts to reduce the roughness have given only a limited improvement since the internal wall of the Teflon tube is not easy to polish (the needed average roughness is less than 10 nm). In previous papers we have reported first results obtained in developing a new type of hollow waveguide for infrared made from polyimide which is a type of plastic with high melting temperature and which can be prepared with very flat surface roughness, less than 10 nm. In this paper we shall present new results of a study made for developing this type of plastic hollow waveguide. The attenuation was reduced to values less than 1 dB. Data about the process of etching for decreasing the roughness of the internal wall of polyimide tube and new methods of deposition of high adhesive and minimal roughness of the Ag and AgI guiding layers will be presented. Results of measurements of attenuation as a function of bending radius, coupled power and time of transmitted radiation will be shown and discussed. New type of dependence of attenuation on bending due to the mechanical properties of the polyimide tubes will be shown and discussed.
Generation and kilohertz rate amplification of synchronized femtosecond and picosecond laser pulses (1989)

Synchronized femtosecond and tunable picosecond laser pulses have been generated using a linear cavity configuration in both lasers. The long-term stability of the synchronization, as well as the frequency of the synchronously pumped femtosecond dye laser, is assured by active stabilization of the cavity length. Additionally, the picosecond and femtosecond pulses have been amplified in dual amplifier chains to pulse energies in the microjoule range at a 1 kHz repetition rate. The total peak intensity available for two-photon, nonlinear excitations is on the order of 10/sup 9/ times greater than that available from unamplified beams.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Local moments in an interacting environment (1998)

We discuss how local moment physics is modified by the presence of interactions in the conduction sea. Interactions in the conduction sea are shown to open up new symmetry channels for the exchange of spin with localized moments. We illustrate this conclusion in the strong-coupling limit by carrying out a Schrieffer-Wolff transformation for a local moment in an interacting electron sea, and show that these corrections become very severe in the approach to a Mott transition.
Analysis of TransTech Model 300 Pavement Quality Indicator: Laboratory and Field Studies for Determining Asphalt Pavement Density (2002)

The pavement quality indicator (PQI) produced by TransTech Systems, Inc., uses principles of electrical impedance and the dielectric constants of materials to determine the densities of asphalt pavements. The Model 300 PQI device was recently evaluated in Illinois as a potential alternative to nuclear density gauges for quality control/quality assurance of asphalt pavement construction. Both laboratory and field testing were conducted to meet these objectives. The PQI has several appealing features relative to the nuclear density gauge, including its light weight and rapid operation in the field without the need for special licensing, handling, or training. The density determined with the nuclear density gauge generally exhibited a closer correlation with the density determined from pavement cores, as denoted by significantly lower squared error of the regression values in the regression analyses performed. Also, although the Model 300 PQI has been improved from earlier models to account for moisture and temperature, the data suggest that the device is still influenced by environmental conditions. On the other hand, the PQI proved to be more operationally convenient for the field technician, being significantly lighter and less time-consuming to operate in the field. On the basis of analysis of the information obtained from the studies, the Illinois Department of Transportation has chosen to base acceptance and statistical pay factors on density values obtained by the AASHTO T166 method with pavement cores. At present, the nuclear density gauge is still the specified device for quality control/quality assurance of asphalt pavement projects in Illinois.
Thermal degradation of electrical insulating materials and the thermokinetic background: experimental data (1990)

For pt.I see ibid., vol.25, 1029-1036, 1990. The purpose of this work is to verify the validity of the new degradation model and the transformation equations which have been developed on the basis of thermokinetic considerations. This verification is implemented by comparing the temperature index (TI) values obtained by the thermal life equations, and their converted forms as transformation equations, for a large amount of material data with TI results estimated by tests carried out according to IEC Standard 216. The TI values relate to insulating materials with constant endurance-line slope as well as to materials with both constant and variable endurance-line slope. These families of life lines are named either parallel or nonparallel life lines. The equations developed provide estimates of the TIs that are, in general, close to those obtained by thermal endurance tests conducted according to IEC 216 procedures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Moments of Two-Variable Functions and the Uniqueness of Graph Limits (2008)

For a symmetric bounded measurable function W on [0,1]^2, "moments" of W can be defined as values t(F,W) indexed by simple graphs. We prove that every such function is determined by its moments up to a measure preserving transformation of the variables. This implies that the limit of a convergent dense graph sequence is unique up to measure preserving transformation.

Hue that is invariant to brightness and gamma (2001)

Hue provides a useful and intuitive cue that is used in a variety of computer vision applications. Hue is an attractive feature as it captures intrinsic information about the colour of objects or surfaces in a scene. Moreover, hue is invariant to confounding factors such as illumination brightness. However hue is not stable to all of the types of confounding factors that one might reasonably encounter. Specifically, the RGBs captured in images are sometimes raised to the power gamma. This is done for two reasons. First, to make the images suitable for display (since monitors have an intrinsic non-linearity). Second, applying a gamma is the simplest way to change the contrast in images. It has also been observed that digital cameras often apply a scene dependent gamma type function (which is unknown to the user). In this paper we show that a simple photometric ratio in log RGB space cancels both brightness and gamma. Furthermore, some simple manipulation reveals that the brightness/gamma invariant can usefully be interpreted as a hue in a log opponent colour space. We carried out indexing experiments to evaluate the usefulness of the derived hue correlate. In situations where gamma is held fixed, the new hue supports recognition equal to conventional definitions. In situations where gamma varies the new correlate supports better indexing. The new hue is also found to predict some psychophysical data quite accurately.
Abstract B48: Aurora kinase A plays a central role in the differentiation, survival, and self-renewal of human neuroblastoma SK-N-BE(2)-derived cancer stem cells (2011)

Abstract Aurora kinase A is upregulated in numerous types of cancers. Since this protein is involved in mitotic spindle formation and cell cycle progression, its dysregulation leads to aberrant chromosomal segregation and consequent aneuploidy. It has been clarified that Aurora A is a key player in neuroblastoma because of its ability to protect the oncogene product N-myc from degradation, and the over-expression of the two of them represents a negative prognostic factor. Neuroblastoma usually develops in children and, up to the present time, the available pharmacological therapies have proven inadequate to treat the MYCN amplified sub-type of cancer, which is the most aggressive and malignant form of the tumor. Therefore, there is an urgency to develop new strategies that will improve its treatment. A novel approach to contrast cancer development and relapse is to target the subpopulation of the tumor initiating cells (or cancer stem cells), due to their multi-drug resistance and self-renewal abilities. In this study, we have employed the SK-N-BE(2) cell line as an in vitro human neuroblastoma model, and compared the effects of Aurora A inhibition on the whole population (WP) and on the derived neurospheres (NS) obtained by their continuous growth in selective medium. We tested the effects of both a specific Aurora A inhibitor, ENMD-2076, and a pan-Aurora isoforms blocker, VX-680, for their influence over cellular physiology, morphology and signaling. The specificity of the results was confirmed by the use of a validated Aurora A siRNA. In SK-N-BE(2) WP and NS, our findings confirmed the ability of Aurora A to protect N-myc from degradation. Moreover, the isolation and characterization by FACS, confocal microscopy and immunoblotting of an aldehyde dehydrogenase-positive side population, confirmed the presence of a fraction of cells with self-renewal capabilities and stem-like properties. The analysis of the signaling network of Aurora A showed functional relationships with the transcription factor STAT3, which is associated with neuronal survival and differentiation, after IL-6 challenge. Furthermore, either Aurora A pharmacological block or silencing induced the phosphorylation of the microtubule associated protein 2 (map2) specifically in the NS, an event that maintains the microtubule in a dynamic state, which is a prerequisite for neurite outgrowth. Our results suggest that Aurora A represents an amenable target for the treatment of neuroblastoma, and gives new insights into its role in regulating neuronal plasticity and differentiation.

Post-transcriptional regulation of the human transforming growth factor-beta 1 gene. (1992)

Since many lines of evidence suggest that expression of the transforming growth factor-beta 1 (TGF-beta 1) gene may be regulated post-transcriptionally, we examined the effect of the 5'-untranslated region (UTR) of this gene on TGF-beta 1 expression. For this purpose, fragments of the 840-nucleotide highly GC-rich TGF-beta 1 5'-UTR were inserted into the 5'-UTR of the structural gene for human growth hormone driven by the simian virus 40 early promoter. A portion of the 5'-UTR of TGF-beta 1 mRNA spanning the sequences from +11 to +147 was shown to inhibit growth hormone expression by as much as 22-fold. This effect was cell-specific; growth hormone production was inhibited in PC-3 human prostate adenocarcinoma and A-549 human lung adenocarcinoma cells, while no effect was seen in rat pheochromocytoma PC12 cells, which show efficient translation of endogenous TGF-beta 1 mRNA. Computer analysis showed that this region of the 5'-UTR contained a stable secondary stem-loop structure spanning sequences +49 to +76. This stem-loop region alone is sufficient to inhibit expression of the growth hormone gene, suggesting that it plays an important role in post-transcriptional regulation of TGF-beta 1 gene expression.
Effect of Core-Corona Plasma Structure on Seeding of Instabilities in Wire Array<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi mathvariant="italic">Z</mml:mi></mml:math>Pinches (2000)

We present the first measurements by x-ray radiography of the development of instabilities during the implosion phase of wire array Z pinches. The seeding of perturbations on the dense core of each wire is provided by nonuniform sweeping of the low-density coronal plasma from the cores by the global JxB force. The spatial scale of these perturbations ( approximately 0.5 mm for Al and approximately 0.25 mm for W) is determined by the size of the wire cores ( approximately 0.25 mm for Al and approximately 0.1 mm for W). A qualitative change in implosion dynamics, with transition to 0D-like trajectory, was observed in Al arrays when the ratio of interwire gap to wire core size was decreased to approximately 3.
Predictors of response to highly active antiretroviral therapy. (2006)

The effective management of HIV-1 infection has evolved dramatically over the past decade. As treatments have become more effective, better tolerated, and easier to take, treatment success as defined by surrogate markers has become increasingly common. Nevertheless, responses to therapy are not uniform, and even in the ideal setting of clinical trials with a select patient population treated with a compact and well-tolerated regimen, up to 20% of patients will fail to achieve sustained antiviral responses. The factors that are predictors of response to antiretroviral therapy, including adherence, stage of disease at baseline, treatment history, and demographic factors, are discussed.
Development of adjustment factors for backfat and loin muscle area from serial real-time ultrasonic measurements on purebred lines of swine. (1998)

We recorded serial real-time ultrasonic measurements of backfat and loin muscle area to assess the rate of change per unit of live weight and growth rate measured as the change in weight per day of age during the finishing stage of production. Barrows (648) and gilts (459) representing eight major U.S. pure breeds of swine were evaluated in the study. Real-time ultrasonic measurements of backfat and loin muscle area were collected at average live weights (LW) of 67.4, 80.3, 93.4, and 104.9 kg. Backfat was measured at the midline over the last rib (LR) and last lumbar vertebra (LL) and off the midline at the 3/4 point (BF10) over the 10th rib. Loin muscle area (LMA) images were collected from the right-hand side of each pig at the 10th rib. Deposition rates were calculated on an intrapig basis for the dependent scan variables BF10, LMA, LR, and LL in models that included the independent variables LW and LW2. For growth rate (WDA), LW was regressed on age and age. Intrapig linear regression coefficients and y-intercepts were further analyzed as dependent variables in a mixed model that included the fixed effects test group, sex, and breed and random effects of sire and dam nested within breed. Significant breed effects were present for deposition rates of BF10, LMA, LR, LL, and WDA. Across the eight breeds, BF10 was deposited at a mean of .271 +/- .008 mm/kg, a rate faster than the average for LR (.201 mm/kg) and LL (.206 mm/kg). The LMA deposition rate across breeds averaged .304 cm2/kg. Average WDA across the breeds was .774 kg. Barrows deposited fat faster at all locations, deposited muscle slower, and grew faster than gilts in this study (P < .001). The results of this study indicate a need for breed- and sex-specific adjustment factors for rates of backfat and loin muscle deposition and for weight per day of age in swine.
The Ethics of Knowledge Transfers and Conversions: Property or Privacy Rights? (2006)

Closely related to organizational learning, knowledge creation, knowledge codification, and knowledge reuse, knowledge transfers of tacit knowledge between individuals and conversions of tacit knowledge to explicit knowledge raise important issues regarding the use of ethics and self-interest as counter determinants. Do organizations "own" the knowledge of their employees, or is this knowledge an "attribute" of an autonomous individual and subject to protection under human rights to privacy or security-of-person? This paper explores these opposite viewpoints from the perspectives of knowledge management and human rights. Consequently, organizational knowledge may fall under the intellectual property theory and organizations have the right to buy, sell and use their corporate knowledge as it suits their needs, while personal knowledge may fall under the personal privacy theory and individuals have the right to protect the security of their personal knowledge. Thus, knowledge management practices may differ with regard to the two types of knowledge.
Regionally Selective and Age‐Dependent Alterations in Benzodiazepine Receptor Binding in the Genetically Dystonic Hamster (1995)

Previous pharmacological studies have indicated that impairment of GABAergic transmission may be involved in the pathophysiology of dystonia in the mutant dtsz hamster, i.e., a genetic animal model for idiopathic dystonia. In the present experiments, the kinetic constants of [3H]flumazenil binding to the benzodiazepine site of the GABAA receptor were calculated from equilibrium binding measurements in various brain regions of genetically dystonic hamsters and age-matched controls. Because dystonia in mutant dtsz hamsters is transient and disappears after approximately 60-70 days of age, [3H]flumazenil binding was studied at the age of maximum severity of dystonia (30-40 days) and after disappearance of the disease, to examine which neurochemical changes were related to dystonia. In mutant hamsters with the maximum severity of dystonia, receptor affinity of [3H]flumazenil was increased in olfactory bulb, striatum, tectum, and cerebellum, as exemplified by significantly decreased dissociation constants (KD) in these regions. An increased number of binding sites (Bmax) were seen in striatum and frontal cortex but not in the other eight regions studied in this regard. All these changes in [3H]flumazenil binding disappeared in parallel with dystonia, implicating a causal relationship between altered benzodiazepine receptor binding and dystonia in mutant dtsz hamsters.(ABSTRACT TRUNCATED AT 250 WORDS)
Learning in the Wild: Coding Reddit for Learning and Practice (2021)

This paper introduces a ‘learning in the wild’ coding schema, an approach developed to support learning analytics researchers interested in understanding the different types of discourse, exploratory talk, and conversational dialogue happening on social media. The research examines how learner-participants (‘Redditors’) are leveraging subreddit communities to facilitate self-directed informal learning practices on the social networking site. The coding schema is tested and applied across four ‘Ask’ subreddit communities (‘AskHistorians’, ‘Ask_Politics’, ‘askscience’, ‘AskAcademia’). The research brings attention to how knowledge, ideas, and resources are being shared and supported outside the confines of traditional education and professional environments.
An integrated methodology for optimizing the passive damping of composite structures (1990)

Abstract A method is presented for tailoring plate and shell composite structures for optimal forced damped dynamic response. The passive damping of specific vibration modes is optimized with respect to dynamic performance criteria including placement of natural frequencies and minimization of resonance amplitudes. The method provides the capability to tailor micromechanics, laminate and structural parameters. Application studies include the optimization of laminated composite beams and composite shells with fiber volume ratios and ply angles as design variables. The results illustrate the significance of damping tailoring to the dynamic performance of composite structures and the effectiveness of the method in optimizing the structural dynamic response.
