Toposculpting is the creation of virtual objects by moving real physical objects through space to extrude patterns like beams and pipes. In one example, a method of making pipe sculptures is proposed, using a ring-shaped object moved through space.
Targeted inactivation of p27kip1 is sufficient for large and small intestinal tumorigenesis in the mouse, which can be augmented by a Western-style high-risk diet. (2003)

Mice with a targeted inactivation of both alleles of the cyclin-dependent kinase inhibitor p27(kip1) developed both small and large intestinal adenomas when fed a control AIN-76A diet. A Western-style diet that is high in fat and phosphate and low in calcium and vitamin D was also able to initiate adenoma formation in wild-type mice. The combination of p27(kip1) inactivation and the Western-style diet was additive in terms of tumor incidence, frequency and size, and in reducing the life span of the mice. The genetic and dietary combination also resulted in development of adenocarcinoma. Tumor formation was linked to a disruption in homeostasis of the intestinal mucosa, involving increased cell proliferation and decreased apoptosis. There was also decreased goblet cell differentiation as assessed by alcian blue staining and expression of the Muc2 gene, especially in mice fed the Western-style diet, although this differentiation lineage was still present as indicated by expression and staining for intestinal trefoil factor. The inactivation of p27(kip1) and the consequent disruption of normal colonic cell maturation in the mucosa were associated with modestly elevated c-myc, cdk4, and cyclin D1 expression. These data establish a fundamental role for p27(kip1) in maintenance of intestinal cell homeostasis and in suppressing tumor formation. The data also emphasize the critical role that dietary factors can have in both tumor initiation and progression through interaction with pathways that normally maintain intestinal homeostasis.

Investigation and development of an advanced virtual coordinate measuring machine (2010)

Dimensional measurement plays a critical role in product development and quality control. With the continuously increasing demand for tighter tolerances and more complex workpiece shapes in the industry, dimensional metrology often becomes the bottleneck of taking the quality and performance of manufacturing to the next level. As one kind of the most useful and powerful measuring instruments, coordinate measuring machines (CMMs) are widely employed in manufacturing industries. Since the accuracy and efficiency of a CMM have a vital impact on the product quality, productivity and manufacturing cost, the evaluation and improvement of CMM performance have always been important research topics since the invention of CMM. A novel Advanced Virtual Coordinate Measuring Machine (AVCMM) is proposed against such a background. The proposed AVCMM is a software package that provides an integrated virtual environment, in which user can plan inspection strategy for a given task, carry out virtual measurement, and evaluate the uncertainty associated with the measurement result, all without the need of using a physical machine. The obtained
Success factors for managing <i>en bloc</i> property transactions (1999)

This paper shows how recent revisions in planning guidelines have helped to enhance land values in some parts of Singapore. The enhancement of land values has motivated many individual property owners to come together to put up their properties for en bloc or collective sales. The factors which are critical for successful en bloc property sales are identified in the paper using case studies where proposed en bloc sales were not successful. These provide lessons which are essential for managing successful en bloc property sales in the future.
Response of Cluster Headache Attacks to Oxygen Inhalation (1981)

SYNOPSIS Fifty‐two randomly selected patients diagnosed as having either active episodic or chronic cluster headaches were evaluated for symptomatic response to oxygen inhalation. At the onset of attacks, 100% oxygen was administered through a facial mask at a rate of 7 liters per minute, for 15 minutes. Each patient self‐treated ten attacks, and timed the rated reduction of pain. A successful treatment result required complete or almost complete reduction of pain in seven of ten attacks, within 15 minutes.In a second (crossover) trial involving an additional 50 patients, sublingual ergotamine tartrate (ErgomarÒ) was compared to oxygen inhalation for symptomatic relief of cluster attacks. Each patient treated ten attacks with either preparation in accordance with the crossover design. Oxygen was administered as described above. Sublingual ergotamine was used every five minutes, to a maximum of three tablets, if necessary.In the first trial 3952 (75%) of patients obtained significant relief from cluster pain. The greatest benefit (92.9%) was found among episodic patients under 50 years of age. The least benefit (57%), was found among chronic patients over 49 years of age. In the second trial, results among oxygen users were better (82%) than those of ergotamine users (70%), but not significantly. Rapidity of relief was similar in both groups.The results of both series indicate that oxygen inhalation is an efficacious symptomatic treatment for cluster attacks. It is superior to ergotamine since there are neither complications nor contraindications to its use. Ergotamine, however, has the advantage of convenience.
An Independent Assessment of the Monthly PRISM Gridded Precipitation Product in Central Oklahoma (2013)

Accurate, long-term records of precipitation are required for the development of climate-informed decision support tools for agriculture. But rain gauges are too sparsely located to meet this need, and radar-derived precipitation measurements are too recent in duration. Using all readily available station records, spatiotemporally continuous estimates of precipitation were created by the PRISM Climate Group to address this problem. As with all interpolated data, the validity of the gridded PRISM product requires validation, and given the extreme spatiotemporal variability of precipitation, such validation is essential. Previous work comparing the monthly precipitation product against contributing rain gauge data revealed inconsistencies that prompted the analysis reported herein. As a basis for checking the accuracy of the PRISM product, independent precipitation data gathered at a USDA research laboratory in central Oklahoma were quality controlled, including comparison to a co-located automated rain gauge operated by the Oklahoma Mesonet. Results indicate that the independent USDA gauge data are of sufficient quality to use in the evaluation of the PRISM product. The area average of the independent USDA data over a matching size area was then used to validate colocated gridded PRISM estimates. The validation results indicate that the monthly gridded PRISM precipitation estimates are close to the independent observed data in terms of means (smaller by 3% to 4.5%) and cumulative probability distributions (within ~4%), but with variances too small by 7% to 11%. From the point of view of agricultural decision support, these results indicate that PRISM estimates might be useful for probabilistic applications, such as downscaling climate forecasts or driving weather generators, assuming appropriate corrections to the higher-order statistics were applied. However, the number of months with potentially significant differences precludes the use of PRISM estimates for any retrospective month-by-month analyses of possible interactions between climate, crop management, and productivity.
Determination of Nitrate in Polluted Water with New Coupling Reagent Hydroxamic Acids : A Rapid and High Potential Reagent for Trace Determination of Nitrate in Polluted Water (2013)

A rapid, stable and direct visible spectrophotometric method, based on the quantitative nitration of hydroxamic acids in concentrated sulphuric acid, is described for determination of nitrate in water samples from different sites of Bhopal. The nitration product was extracted in n-hexane and yellow complex formed was determined at 462 nm, 458 nm and 450 nm for N-PBHA, N-PClPBHA and N-PClPCHA, respectively. The calibration graph was linear over the range of 0.0001965-0.002751, 0.001965-0.03931 and 0.001965-0.02554 µg/25 ml for N-PBHA, N-PClPBHA and N-PClPCHA, respectively. The molar absorptivities were found to be 3.81x10 6 , 2.65x10 5 and 4.11x10 5 L mol -1 cm -1 for the above three hdroxamic acids. The accuracy of method did not depend on nitrate contents. Key words: Nitrate, Hydroxamic acid, Water, Spectrophotometry, Potential.
Pentafluorobenzylation Method for Quantification of Acidic Tryptophan Metabolites Using Electron Capture Negative Ion Mass Spectrometry (1995)

An improved pentafluorobenzylation method was developed for derivatization of L-tryptophan and its acidic metabolites (L-kynurenine, kynurenic acid, anthranilic acid, xanthurenic acid, 3-hydroxyanthranilic acid, picolinic acid, quinolinic acid) present at trace levels in aqueous samples. This method employs lyophilization of aqueous samples in the presence of excess tetrabutylammonium hydrogen sulfate, followed by base-catalyzed anhydrous pentafluorobenzylation. A comparison with other published methods shows the advantage of this modification for the derivatization of kynurenine metabolites. The derivatives were analyzed by gas chromatography/electron capture negative ion mass spectrometry (GC/ECNI-MS) or liquid chromatography/particle beam/ECNI-MS (LC/ECNI-MS). The detection limits for injected standards are in the femtogram range by GC/ECNI-MS and in the low picogram range by LC/ECNI-MS. GC/ECNIMS is 3.6 (xanthurenic acid) to 66 (quinolinic acid) times more sensitive than LC/ECNI-MS. The simultaneous determination of two neuroactive metabolites, quinolinic and kynurenic acids, in culture medium is presented. The minimum measurable concentrations of these metabolites in 100 microL of culture medium are 0.11 nM for quinolinic acid and 0.21 nM for kynurenic acid.

Selective activation of mouse T and B lymphocytes by periodate, galactose oxidase and soybean agglutinin (1974)

Abstract Modifications of surface saccharides of mouse spleen cells wirh periodate (NaIO 4 ) or with neuraminidase and galactose oxidase induced extensive blastogenesis. The mitogenic effects of these agents on purified thymus‐derived lymphocytes (T cells) and bone marrow‐derived lymphocytes (B cells) were investigated. Thymus cells were stimulated after treatment with NaIO 4 or with neuraminidase and galactose oxidase. The stimulation of these cells was markedly enhanced upon addition of a lymphocyte‐activating factor obtained from human leukocyte culture. Spleen cells from congenitally athymic mice did not respond to treatment with NaIO 4 or with neuraminidase and galactose oxidase. Spleen cells from mice deprived of T cells by thymectomy, irradiation and bone marrow reconstitution, responded poorly to the above mentioned agents. It was concluded that periodate or treatment with neuraminidase and galactose oxidase stimulates exclusively T cells. Soybean agglutinin (SBA) had selective effects on T and B mouse lymphocytes. Neuraminidase treatment rendered T cells highly responsive to stimulation by SBA. On the other hand the small but significant stimulation of B cells by SBA is reduced after treatment of the cells with neuraminidase. SBA stimulates B cells and neuraminidase‐treated T cells by interaction with galactose‐like sites.
Increased Expression of the Collagen Internalization Receptor uPARAP/Endo180 in the Stroma of Head and Neck Cancer (2006)

Local growth, invasion, and metastasis of malignancies of the head and neck involve extensive degradation and remodeling of the underlying, collagen-rich connective tissue. Urokinase plasminogen activator receptor-associated protein (uPARAP)/Endo180 is an endocytic receptor recently shown to play a critical role in the uptake and intracellular degradation of collagen by mesenchymal cells. As a step toward determining the putative function of uPARAP/Endo180 in head and neck cancer progression, we used immunohistochemistry to determine the expression of this collagen internalization receptor in 112 human squamous cell carcinomas and 19 normal or tumor-adjacent head and neck tissue samples from the tongue, gingiva, cheek, tonsils, palate, floor of mouth, larynx, maxillary sinus, upper jaw, nasopharynx/nasal cavity, and lymph nodes. Specificity of detection was verified by staining of serial sections with two different monoclonal antibodies against two non-overlapping epitopes on uPARAP/Endo180 and by the use of isotype-matched non-immune antibodies. uPARAP/Endo180 expression was observed in stromal fibroblast-like, vimentin-positive cells. Furthermore, expression of the collagen internalization receptor was increased in tumor stroma compared with tumor-adjacent connective tissue or normal submucosal connective tissue and was most prominent in poorly differentiated tumors. These data suggest that uPARAP/Endo180 participates in the connective tissue destruction during head and neck squamous cell carcinoma progression by mediating cellular uptake and lysosomal degradation of collagen.

Blue, Green and White InGaN Light-Emitting Diodes Grown on Si (2005)

High-brightness InGaN light-emitting diodes (LEDs) have been grown on Si substrates by metal-organic vapor phase epitaxy. Both blue and green LEDs with an output power exceeding 0.7 mW and a lifetime exceeding 500 h were achieved. Two factors were analyzed: the difference between identical LED structures grown on Si and sapphire substrates, and the effect of cracking on the performance of LEDs grown on Si. Using a Si substrate, the LED emission showed a shift toward longer wavelength compared with that from a LED grown on sapphire. The presence of cracking, unless serious, showed little effect on the brightness and performance of the LEDs grown on Si. The mechanisms involved are discussed.
Encapsulation of Methane and Other Small Molecules in a Self-Assembling Superstructure (1994)

Physical inclusion of small molecules in larger structural lattices is well known in the crystalline state and is a common feature of the chemistry of zeolites. In the liquid state, a variety of synthetic macrocyclic molecules are available to complex and contain smaller guest species. An alternative strategy for binding is explored: assembly of cavity-forming structures from small subunits. Encapsulation of small guest molecules such as methane can be achieved with a synthetic structure that assembles reversibly through hydrogen bonding.
Fast Positioning and Impact Minimizing of MEMS Devices by Suppression of Motion-Induced Vibration by Command-Shaping Method (2011)

Electrostatic (ES) force is one of the most important actuation mechanisms for microelectromechanical systems (MEMS) devices. However, residual vibration of microstructures induced by ES actuation can bring various problems that degrade dynamic performance and device longevity, such as long settling time, dynamic pull-in, and contact fatigue. By suppressing this undesirable effect, it is expected that both the dynamic performance and device reliability can be effectively enhanced. This paper presents a command-shaping-based scheme with experiment validation for both fast positioning and reduced contact impact of MEMS devices by the suppression of motion-induced vibrations. The scheme was developed by applying energy conservation, force equilibrium, and elliptical integrals. Simulink simulations indicate that both the impact force and settling time can be effectively reduced. In order to count the possible parameter variation and unmodeled dynamics, an online tuning scheme is also proposed and verified through simulation. Finally, spring-plate specimens fabricated using SU-8 with a metallic coating and a test bed containing a laser positioning sensor and a high voltage source are designed to further demonstrate the performance of the proposed scheme; the test results indicate that the proposed approach can effectively enhance the dynamic performance of MEMS devices such as grating light valves and RF switches.
Dog ownership and the risk of cardiovascular disease and death – a nationwide cohort study (2017)

Dogs may be beneficial in reducing cardiovascular risk in their owners by providing social support and motivation for physical activity. We aimed to investigate the association of dog ownership with incident cardiovascular disease (CVD) and death in a register-based prospective nation-wide cohort (n = 3,432,153) with up to 12 years of follow-up. Self-reported health and lifestyle habits were available for 34,202 participants in the Swedish Twin Register. Time-to-event analyses with time-updated covariates were used to calculate hazard ratios (HR) with 95% confidence intervals (CI). In single- and multiple-person households, dog ownership (13.1%) was associated with lower risk of death, HR 0.67 (95% CI, 0.65-0.69) and 0.89 (0.87-0.91), respectively; and CVD death, HR 0.64 (0.59-0.70), and 0.85 (0.81-0.90), respectively. In single-person households, dog ownership was inversely associated with cardiovascular outcomes (HR composite CVD 0.92, 95% CI, 0.89-0.94). Ownership of hunting breed dogs was associated with lowest risk of CVD. Further analysis in the Twin Register could not replicate the reduced risk of CVD or death but also gave no indication of confounding by disability, comorbidities or lifestyle factors. In conclusion, dog ownership appears to be associated with lower risk of CVD in single-person households and lower mortality in the general population.
