La novata estará a la altura (2009)

Una semana antes de Navidad, Tim O�Connell, alto ejecutivo de Driscoll Software, recibe una llamada de Hybara Casinos. El sistema del ex cliente ha estado fallando y la empresa quiere que se solucione el problema antes de la noche de Ano Nuevo. El proyecto generara ingresos que son cruciales para la empresa, pero implica quemarse las pestanas durante dos semanas para realizar un trabajo que normalmente toma seis semanas; y ademas, durante las fiestas de fin de ano. La programadora estrella de Tim, Alessandra Sandoval, dejo la empresa hace varios meses y la novata Kristen Hammersmith la reemplazo. ?Deberia Tim contratar a Alessandra para que realice el proyecto o confiar en Kristen para que lidere el equipo?
Michael Schrage, investigador de Center for Digital Business de Sloan School del MIT, senala que deberia contratar a Alessandra inmediatamente. Kristen esta completamente sobrepasada. Pero mucho mas importante es que Tim es un ejecutivo con un desempeno alarmantemente malo. 

Carol A. Walker, la fundadora y directora de la firma consultora Prepared to Lead, concuerda con el hecho de que Tim no esta haciendo su trabajo, y ofrece un escenario posible donde demuestra su confianza en Kristen y la apoya para ayudarla a tener exito en este proyecto.

Paul Muller, vicepresidente de marketing estrategico para los productos de software de Hewlett-Packard, dice que en este plazo tan severamente comprimido, Driscoll e Hybara necesitan evaluar los riesgos involucrados y las implicancias de los costos al tratar de apurar el proyecto. Si deciden seguir adelante, Tim deberia empoderar a Kristen para que lidere el proyecto.
Microregional Effects of Gemcitabine in HCT-116 Xenografts (2004)

To examine the tumor microregional effects after gemcitabine administration to mice, we mapped the location of proliferating and hypoxic cells relative to vasculature in human colon cancer xenografts. The S-phase marker bromodeoxyuridine was used as a surrogate of drug effect and administered 2 hours before tumor excision, whereas vessel position and perfusion were assessed via staining for CD31 and intravenous injection of carbocyanine, respectively. Hypoxia was detected using pimonidazole. Images of the four markers were overlaid to reveal the spatial relationship between proliferation, vasculature, and hypoxia and to examine the microregional effects. Within 1 day after administration of 240 mg/kg of gemcitabine, proliferation throughout the tumor was completely inhibited. Over time, a reemergence of dividing cells occurred in relation to the distance from vasculature. Microregional analysis revealed that cells located distal to vasculature commenced cycling sooner than cells located proximal to vasculature. A similar trend was seen after multiple doses of gemcitabine (40 mg/kg on days 1, 4, 7, and 10). The possibility that the effect of gemcitabine could be attributed to changes in oxygenation was discounted after examining the vessel perfusion and patterns of hypoxia. The effect of gemcitabine was examined in multilayered cell culture, and at doses <30 micromol/L, a gradient in proliferation between the exposed and unexposed sides was observed. We show a differential effect on cell proliferation in relation to vasculature and conclude that cells distal to blood vessels are less affected by gemcitabine probably because of limited penetration.
Isolation and analysis of the gene and cDNA for a human Mu class glutathione S-transferase, GSTM4 (1993)

We have isolated the human gene and cDNA that encode the fourth member of the Mu class glutathione S-transferases (GSTs). The complete gene sequence (GenBank M96233) and the cDNA sequence (M96234) are reported and named GSTM4. The gene, located on chromosome 1, is comprised of eight exons with an organization similar to that of other Mu class genes. GSTM4 differs from a partial gene sequence, termed GSTmu2 (Taylor, J. B., Oliver, J., Sherrington, R., and Pemble, S. E. (1991) Biochem. J. 274, 587-593), in exons 3 through 5 by only 11 nucleotides within introns. The cDNA for GSTM4 was isolated from a library derived from the cervical carcinoma cell line, HeLa. Northern blots demonstrate the presence of GSTM4 mRNA in human heart, placenta, lung, brain, liver, skeletal muscle, pancreas, testis, cerebral cortex, uterus, ovary, a lymphoblastoid cell line, and four carcinoma cell lines. The deduced amino acid sequence of GSTM4 is 87% (GSTM1), 83% (GSTM2), and 70% (GSTM3) identical to the previously described human Mu class GSTs. The polypeptide encoded by the GSTM4 cDNA, produced in a bacterial expression system, conjugates 1-chloro-2,4-dinitrobenzene to GSH with a specific activity of 1.39 +/- 0.21 mumol/min/mg.
Effect of Cr Content and Water Vapor on Fracture Behavior of the Scales Formed on Fe and Fe-Cr Alloy (2006)

Isothermal oxidation was carried out on Fe and Fe-(1.0 and 5.0mass%)Cr alloy at 800°C and 1000°C in dry (PH2O=1x10-4 atm) and wet (PH2O=0.035 atm) air. Fracture behavior of the scale was investigated using acoustic emission (AE) analysis during cooling. The water vapor content of the atmosphere has a major influence on the oxidation of the Fe-Cr alloys, whereas it has virtually no effect on the oxidation of Fe. During cooling, significant AE activity starts at about 450°C on the Fe and Fe-Cr alloys oxidized in wet air. This critical temperature is independent of sample composition, oxidation temperature and scale thickness. In the case of the oxidation of the Fe-Cr alloys in dry air, however, the critical temperature shifts to higher temperatures with increasing scale thickness and Cr content. Fracture behavior of the scale should be related to scale structure caused by sample composition and oxidation condition.
Metal/metal oxide doped oxide catalysts having high deNOx selectivity for lean NOx exhaust aftertreatment systems (2023)

A lean NOx catalyst and method of preparing the same is disclosed. The lean NOx catalyst includes a ceramic substrate, an oxide support material, preferably .gamma.-alumina, deposited on the substrate and a metal promoter or dopant introduced into the oxide support material. The metal promoters or dopants are selected from the group consisting of indium, gallium, tin, silver, germanium, gold, nickel, cobalt, copper, iron, manganese, molybdenum, chromium, cerium, vanadium, oxides thereof, and combinations thereof. The .gamma.-alumina preferably has a pore volume of from about 0.5 to about 2.0 cc/g; a surface area of between about 80 to 350 m.sup.2 /g; an average pore size diameter of between about 3 to 30 nm; and an impurity level of less than or equal to 0.2 weight percent. In a preferred embodiment the .gamma.-alumina is prepared by a sol-gel method, with the metal doping of the .gamma.-alumina preferably accomplished using an incipient wetness impregnation technique.
Working hard to know your neighbor's margins: Local descriptor learning loss (2017)

We introduce a loss for metric learning, which is inspired by the Lowe's matching criterion for SIFT. We show that the proposed loss, that maximizes the distance between the closest positive and closest negative example in the batch, is better than complex regularization methods; it works well for both shallow and deep convolution network architectures. Applying the novel loss to the L2Net CNN architecture results in a compact descriptor named HardNet. It has the same dimensionality as SIFT (128) and shows state-of-art performance in wide baseline stereo, patch verification and instance retrieval benchmarks.
Prediction of paclitaxel sensitivity by CDK1 and CDK2 activity in human breast cancer cells (2009)

The change in CDK1 specific activity of xenograft tumors after paclitaxel treatment and the CDK2 specific activity before paclitaxel treatment are both associated with the drug sensitivity in vivo. Analysis of cyclin-dependent kinase activity in the clinical setting could be a powerful approach for predicting paclitaxel sensitivity.
Improved ROI video coding using variable Gaussian pre-filters and variance in intensity (2005)

In applications involving video over mobile phones or Internet, the limited quality depending on the transmission rate can be further improved by region-of-interest (ROI) coding. In this paper we present a preprocessing method using variable Gaussian filters controlled by a quality map indicating the distance to the ROI border. The border effects are reduced introducing a small improvement of the PSNR of the intensity component within the ROI after compression, compared to using only one low pass filter. With the compressed original sequence as a reference, the average PSNR was increased by 1.25 dB and 2.3 dB for 100 kbit/s and 150 kbit/s, respectively. A modified quality map is introduced using variance to exclude pixels, which are not visibly affected by the Gaussian filters, reducing computational complexity. Using less than 76% of the pixels gives no noticeable change in quality.

Simulation and Analysis of ECT Signals Obtained at Tubesheet and Tube Expansion Area (2006)

Steam generator (SG) tubes are expanded inside tubesheet holes by using explosive or hydraulic methods to be fixed in a tubesheet. In the tube expansion process, it is important to minimize the crevice gap between expanded tube and tube sheet. In this paper, absolute and differential signals are computed by a numerical method for several different locations of tube expansion inside and outside a tubesheet and signal variations due to tubesheet, tube expansion and operating frequencies are observed. Results show that low frequency is good for detecting tubesheet location in both types of signals and high frequency is suitable for sizing of tube diameter as well as the detection of transition region. Also learned is that the absolute signal is good for measuring tube diameter, while the differential signal is good for locating the top of tubesheet and both ends of the transition region. In the case of mingled anomaly with tube expansion and tubesheet, low frequency inspection is found to be useful to analyze the mixed signal.
Mimo Cellular Networks With Simultaneous Wireless Information And Power Transfer (2016)

In this paper, we introduce a mathematical approach for system-level analysis and optimization of densely deployed multiple antenna cellular networks, where low-energy devices are capable of decoding information data and harvesting power simultaneously. The base stations are assumed to be deployed according to a Poisson point process and tools from stochastic geometry are exploited to quantify the trade-off in terms of information rate and harvested power. It is shown that multiple-antenna transmission is capable of increasing information rate and harvested power at the same time.
Identical NC-code on Different Machine Tools – Similarities and Differences in Timing and Positioning (2023)

Process and tool condition monitoring systems are a prerequisite for autonomous production. For online monitoring, it is the state of the art to use reference signals of correct processes to improve failure sensitivity and reduce false alarms. Transferring these reference signals from other machines economizes on teach-in processes and complex simulations. However, the varying behaviour of the two machines leads to differences that need to be considered for the transfer. This work aims to identify similarities and differences in the timing and positioning of multiple machines when executing identical machining instructions. A comparison of process signals quantifies similarities and differences among machines. Results describe differences between process sequences, rapid traverse speeds, rapid traverse paths, machining feed speeds, machining feed paths, tool engagement time, and the temporal alignment of signals. Differences primarily originated from different control parameters and strategies as well as physical drive limitations. During machining differences occurred most frequently when axes were accelerated. Differences accumulated over prolong periods of machining and eventually became relevant from the perspective of online monitoring.

Role of adenosine in sleep in rats. (1987)

The effects on sleep of N6-L-(phenylisopropyl) adenosine, cyclohexyladenosine and adenosine-5'-ethylcarboxamide were studied in rats. Also, the effects on sleep of deoxycoformycin, a potent inhibitor of adenosine deaminase, and adenosine were examined. In addition, we determined the effects of 48 h of REM sleep deprivation on adenosine (A1) receptors in specific brain structures. N6-L-(phenylisopropyl) adenosine and cyclohexyl-adenosine increased deep slow wave sleep and REM sleep whereas adenosine-5'-ethylcarboxamide increased only deep slow-wave sleep. At the dose of 0.9 mumol/kg all three adenosine analogs suppressed REM sleep and except for adenosine-5-ethylcarboxamide, were without an effect on deep slow-wave sleep. In accordance, administration of deoxycoformycin increased REM and deep slow-wave sleep. Intracerebroventricular administration of 1, 10 and 100 nmoles of adenosine to rats decreased waking, increased deep slow-wave sleep and increased total sleep. In addition, REM sleep deprivation significantly increased the number of A1 receptors (Bmax) in cerebral cortex and corpus striatum which correlates with the increased pressure for REM sleep and the onset of REM sleep rebound. When these data are taken together, they indicate a role for adenosine in the regulation of sleep and, in contrast to barbiturate and benzodiazepine hypnotics, increase in behaviorally deep and REM sleep.
Immediate and Deferred Imitation in Fourteen-and Twenty-Four-Month-Old Infants (1985)

MELTZOFF, ANDREW N. Immediate and Deferred Imitation in Fourteenand Twenty-Four-MonthOld Infants. CHILD DEVELOPMENT, 1985, 56, 62-72. A laboratory procedure is developed that can be used to assess imitation in the second year of life. The procedure uses a blind scoring technique and incorporates control conditions to distinguish infant imitation from spontaneous production of the target behavior. The procedure is used in 2 experiments evaluating the imitation of a simple action with a novel toy. The experiments assess both immediate and deferred imitation in each of 2 age groups, 14-month-olds and 2-year-olds. The deferred imitation task involved a 24-hour delay between the modeling and response periods. There was strong evidence that 2-year-old infants could perform both the immediate and deferred imitation tasks, which was expected. The results also showed that 14-month-olds could succeed in both tasks. The discussion considers the implications of the deferred imitation results in light of current data and theorizing concerning representational capacities and long-term memory in infancy.

Multiexpert Automatic Speech Recognition Using Acoustic and Myoelectric Signals (2006)

Classification accuracy of conventional automatic speech recognition (ASR) systems can decrease dramatically under acoustically noisy conditions. To improve classification accuracy and increase system robustness a multiexpert ASR system is implemented. In this system, acoustic speech information is supplemented with information from facial myoelectric signals (MES). A new method of combining experts, known as the plausibility method, is employed to combine an acoustic ASR expert and a MES ASR expert. The plausibility method of combining multiple experts, which is based on the mathematical framework of evidence theory, is compared to the Borda count and score-based methods of combination. Acoustic and facial MES data were collected from 5 subjects, using a 10-word vocabulary across an 18-dB range of acoustic noise. As expected the performance of an acoustic expert decreases with increasing acoustic noise; classification accuracies of the acoustic ASR expert are as low as 11.5%. The effect of noise is significantly reduced with the addition of the MES ASR expert. Classification accuracies remain above 78.8% across the 18-dB range of acoustic noise, when the plausibility method is used to combine the opinions of multiple experts. In addition, the plausibility method produced classification accuracies higher than any individual expert at all noise levels, as well as the highest classification accuracies, except at the 9-dB noise level. Using the Borda count and score-based multiexpert systems, classification accuracies are improved relative to the acoustic ASR expert but are as low as 51.5% and 59.5%, respectively.
Analysis of TV White Space Availability in Japan (2012)

This paper analyzes TV white space (TVWS) availability in Japan by estimating the amount and distribution of TVWSs across Japan and comparing them with those across the USA. While TVWS regulation is still under discussion in Japan, the expected availability is likely to be more encouraging than that in the USA. Japanese metropolitan areas tend to have more available channels than those in the USA. Including the Tokyo metropolitan area which is the most populated area in Japan, 84.3% of areas (66.7% of the population) may expect greater than 100-MHz TVWSs. The Tokyo metropolitan area is also relatively unaffected by restricted use of the adjacent channel or increase in separation distance.
The Link Between Necessity And Randomness In Scientific Discovery (2019)

The article is devoted to the problem of the link between the essential and the accidental in the process of scientific discoveries. The author criticises Karl Popper concept who states that each scientific discovery is entirely “accidental”. The author‟ viewpoint is based on the methodology of dialectical materialism as a whole, the concept of dialectical determinism, current works on the theory of truth and the criterion of truth. The article treats randomness as the form of being and the phenomenon of necessity. The randomness is presented in the act of discovery by a variety of phenomena such as the particular time, the author of the discovery and the specific aspect of the scientific problem determining this discovery. The necessity here has to do with a specific measure reflecting the limits of change for the phenomenal side of scientific discovery, and this is true for other objective and subjective processes. The author argues that revealing the link between the essential and the accidental in scientific discovery is a critical foundation for solving all epistemological problems, the problem of the criterion of the truth in the first place.
Two-Year Responses of Office and Ambulatory Blood Pressure to First Occupational Lead Exposure (2020)

Lead exposure causing hypertension is the mechanism commonly assumed to set off premature death and cardiovascular complications. However, at current exposure levels in the developed world, the link between hypertension and lead remains unproven. In the Study for Promotion of Health in Recycling Lead (URL: https://www.clinicaltrials.gov; Unique identifier: NCT02243904), we recorded the 2-year responses of office blood pressure (average of 5 consecutive readings) and 24-hour ambulatory blood pressure to first occupational lead exposure in workers newly employed at lead recycling plants. Blood lead (BL) was measured by inductively coupled plasma mass spectrometry (detection limit 0.5 µg/dL). Hypertension was defined according to the 2017 American College of Cardiology/American Heart Association guideline. Statistical methods included multivariable-adjusted mixed models with participants modeled as a random effect and interval-censored Cox regression. Office blood pressure was measured in 267 participants (11.6% women, mean age at enrollment, 28.6 years) and ambulatory blood pressure in 137 at 2 follow-up visits. Geometric means were 4.09 µg/dL for baseline BL and 3.30 for the last-follow-up-to-baseline BL ratio. Fully adjusted changes in systolic/diastolic blood pressure associated with a doubling of the BL ratio were 0.36/0.28 mm Hg (95% CI, -0.55 to 1.27/-0.48 to 1.04 mm Hg) for office blood pressure and -0.18/0.11 mm Hg (-2.09 to 1.74/-1.05 to 1.27 mm Hg) for 24-hour ambulatory blood pressure. The adjusted hazard ratios of moving up across hypertension categories for a doubling in BL were 1.13 (0.93-1.38) and 0.84 (0.57-1.22) for office blood pressure and ambulatory blood pressure, respectively. In conclusion, the 2-year blood pressure responses and incident hypertension were not associated with the BL increase on first occupational exposure.
