Effect of Production Temperature on Deformation and Tensile-related Properties of Modified Warm-Mix Asphalt concretes (2015)

When an styrene-butadiene-styrene (SBS) mixture is produced in warm mix asphalt (WMA) technology, the materials should be heated to a level high enough to maintain its workability due to its highly viscous nature. The SBS-modified hot mix asphalt (HMA) (MHMA) mixtures are produced at approximately 20-30°C higher than normal (unmodified) mixtures. If a modified WMA (MWMA) mixture is produced at a lower temperature, the MWMA mixture will be weaker than the HMA due to the incomplete aggregate drying and binder coating. Therefore, using an adequately high short-term aging temperature (STAT) is important for MWMA mixtures. This study examined STATs for SBS MWMA mixtures based on two high-temperature properties (wheel tracking: WT, and deformation strength: SD), and one ambient-temperature property (indirect tensile strength: ITS), using four SBS brands. MWMA mixtures were prepared in three different WMA level STATs of 125, 135 and 145°C. Statistical analyses showed that the three properties of the mixtures produced by a STAT of 125°C were significantly lower than those of other STATs, at an α = 0.05 level. The STATs of 135°C and 145°C were acceptable for certain SBSs, but not for others. Therefore, properties of SBS MWMA mixtures were highly dependent upon STATs which significantly affect the workability and compaction. Since MHMA mixes showed significantly better properties than MWMA mixes, temperatures higher than 145°C may be required for some MWMA mixes to perform similarly to the HMA PMA mixes. However, it may still not be possible that the MWMA mix is comparable or better than MHMA at high-service temperatures, as long as the WMA level STAT is used.

The effects of an anabolic steroid (oxandrolone) on reproductive development in the male rat (1992)

Oxandrolone is a 5 alpha-reduced anabolic steroid that is administered for the treatment of short stature disease in children. It is a commonly used substance beginning as early as prepuberty by some individuals who are seeking to enhance athletic performance or personal appearance. Because of the lack of data on the effects of anabolic steroids on the reproductive system, we have examined the effects of oxandrolone treatment on reproductive development in male rats with treatment beginning two days after weaning. Male, Sprague-Dawley rats (N = 12) received a daily subcutaneous injection of oxandrolone (32.7 mumol.kg-1.day-1) and the control group (N = 12) received vehicle only (dimethyl sulfoxide). Treatment began at age 23 days and continued to 60 days of age. The weights of the testes, prostate glands, and seminal vesicles in the treatment group were 69%, 50% and 29% below control levels, respectively and were all significantly decreased (p less than 0.01). Testicular testosterone production in a 3-h incubation was inhibited in the treated animals to 1.3% of control values (p less than 0.001). Serum FSH (11.7% of control) and LH (undetectable) in the treated animals were both significantly less than controls. Histological findings indicated an arrest of advanced spermatids and a severe depletion of Leydig cells in the interstitial compartment. It was concluded that treatment of immature male rats with oxandrolone results in effects on the adult male reproductive system which are profound and occur at several levels. The most likely affected sites are the hypothalamus, pituitary gland, and the Leydig cells.
Throughput Analysis of Linear Cluster Tools (2007)

In this paper, we analyze steady-state throughput and scheduling of linear cluster tools with single-blade robots in semiconductor manufacturing. We extend the existing research results in throughput and scheduling analysis for regular cluster tools to linear cluster tools. We analyze the tool's throughput for typical single and separate input/output configurations. We also consider a general distribution of the parallel process modules. We present a few examples of linear cluster tools to illustrate the proposed decomposition method and algorithms. The numerical results demonstrate that the proposed approach provides a powerful method to analyze the throughput and robot schedules of newly developed linear cluster tools.
Report 3: Transmissibility of 2019-nCoV (2020)

Self-sustaining human-to-human transmission of the novel coronavirus (2019-nCov) is the only plausible explanation of the scale of the outbreak in Wuhan. We estimate that, on average, each case infected 2.6 (uncertainty range: 1.5-3.5) other people up to 18th January 2020, based on an analysis combining our past estimates of the size of the outbreak in Wuhan with computational modelling of potential epidemic trajectories. This implies that control measures need to block well over 60% of transmission to be effective in controlling the outbreak. It is likely, based on the experience of SARS and MERS-CoV, that the number of secondary cases caused by a case of 2019-nCoV is highly variable – with many cases causing no secondary infections, and a few causing many. Whether transmission is continuing at the same rate currently depends on the effectiveness of current control measures implemented in China and the extent to which the populations of affected areas have adopted risk-reducing behaviours. In the absence of antiviral drugs or vaccines, control relies upon the prompt detection and isolation of symptomatic cases. It is unclear at the current time whether this outbreak can be contained within China; uncertainties include the severity spectrum of the disease caused by this virus and whether cases with relatively mild symptoms are able to transmit the virus efficiently. Identification and testing of potential cases need to be as extensive as is permitted by healthcare and diagnostic testing capacity – including the identification, testing and isolation of suspected cases with only mild to moderate disease (e.g. influenza-like illness), when logistically feasible.
Removal of Hazardous Organic Pollutants by Adsorption on Microbial Biomass (1987)

Removal of five toxic organic compounds from water by adsorption on microbial biomass was investigated. Lindane, diazinon, malathion, pentachlorophenol, and the PCB 2-chlorobiphenyl were adsorbed onto two types of inactive microbial biomass (a pure strain of Rhizopusarrhizus, and a mixed culture of activated sludge). Desorption and the thermodynamics of the adsorption process were also investigated. With the exception of malathion, the adsorptive uptake data fit the Freundlich equation and were well correlated with the octanol/water partition coefficient, but not as well correlated with water solubility of the compounds. Except for malathion the adsorption was reversible. Malathion showed unusually high apparent uptake and the removal appeared to be irreversible. The experimental evidence suggests that the disappearance of malathion resulted from a chemical reaction, while physical adsorption appears to account for removal of the other compounds.
A saliency based noise reduction method for Digital TV (2011)

In this paper, we propose a content-aware noise reduction (NR) method for the Digital TV, which preserves image textures and edges. In the proposed method, noise is first reduced by a temporal recursive NR filter and then further suppressed by a spatial NR filter. To preserve the image texture, the saliency map which accurately represents edges in a noisy image is employed in the spatial filter. Experimental results show that the proposed method exhibits the better NR performance as compared with conventional methods.
Complete cardiac regeneration in a mouse model of myocardial infarction (2012)

Cardiac remodeling and subsequent heart failure remain critical issues after myocardial infarction despite improved treatment and reperfusion strategies. Recently, complete cardiac regeneration has been demonstrated in fish and newborn mice following resection of the cardiac apex. However, it remained entirely unclear whether the mammalian heart can also completely regenerate following a complex cardiac ischemic injury. We established a protocol to induce a severe heart attack in one-day-old mice using left anterior descending artery (LAD) ligation. LAD ligation triggered substantial cardiac injury in the left ventricle defined by Caspase 3 activation and massive cell death. Ischemia-induced cardiomyocyte death was also visible on day 4 after LAD ligation. Remarkably, 7 days after the initial ischemic insult, we observed complete cardiac regeneration without any signs of tissue damage or scarring. This tissue regeneration translated into long-term normal heart functions as assessed by echocardiography. In contrast, LAD ligations in 7-day-old mice resulted in extensive scarring comparable to adult mice, indicating that the regenerative capacity for complete cardiac healing after heart attacks can be traced to the first week after birth. RNAseq analyses of hearts on day 1, day 3, and day 10 and comparing LAD-ligated and sham-operated mice surprisingly revealed a transcriptional programme of major changes in genes mediating mitosis and cell division between days 1, 3 and 10 postnatally and a very limited set of genes, including genes regulating cell cycle and extracellular matrix synthesis, being differentially regulated in the regenerating hearts. We present for the first time a mammalian model of complete cardiac regeneration following a severe ischemic cardiac injury. This novel model system provides the unique opportunity to uncover molecular and cellular pathways that can induce cardiac regeneration after ischemic injury, findings that one day could be translated to human heart attack patients.

Stream computing based synchrophasor application for power grids (2011)

This paper proposes an application of stream computing analytics framework to high speed synchrophasor data for real time monitoring and control of electric grid. High volume streaming synchrophasor data from geographically distributed grid sensors (namely, Phasor Measurement Units) are collected, synchronized, aggregated when required and analyzed using a stream computing platform to estimate the grid stability in real time. This real time stability monitoring scheme will help the grid operators to take preventive or corrective measures ahead of time to mitigate any disturbance before they develop into wide-spread. A protptype of the scheme is demonstrated on a benchmark 3 machines 9 bus system and the IEEE 14 bus test system.
Nucleotide sequence of a hepatitis B virus genome of subtype adw isolated from a Philippine: Comparison with the reported three genomes of the same subtype (1988)

ABSTRACT The complete nucleotide sequence was determined for a hepatitis B virus genome of subtype adw (pFDW294) isolated and cloned from the plasma sample of a Philippino. The genome was 3221 base‐pair long with a point mutation at the 1376th nucleotide that affected the coding capacity of the P and X genes. There was a wide range of sequence divergence among pFDW294 and the reported three genomes of the same subtype (1.1–9.9%), occurring more often in the pre‐S region and the S gene than in the pre‐C region and the C gene.
New tools and methodology for advanced parametric and defect structure test (2010)

Continuing scaling trends in semiconductor technology, as well as the test requirements of new technologies being incorporated with mainstream silicon integrated circuits, has increased the complexity of parametric and defect structure testing. New testers are required which can drastically improve the throughput of parametric test, as well as efficiently test new array based process diagnostic structures. Addressing these needs requires merging the traditionally separate functions of digital and parametric test equipment. We describe the development of a new hybrid test system, which combines the features of parametric and digital testers, and in addition introduces a high degree parallelism in its parametric test functions. The test system was developed for high throughput inline test (“parallel test”) of defect structures, semiconductor parametric macros, and advanced array based process monitors down to pA current levels, as well as traditional all digital yield macros, such as SRAMs.
Histogenetic variation in flowers of Angelonia Humb. et Bonpl. (2012)

Angelonia, a genus of the family Scrophulariaceae, provides new flowering pot plants. The flower colour of Angelonia hybrids ranges from blue to violet, white and pink. Bicoloured Angelonia hybrids are grown in horticultural production. Here, the reasons for bicolourness in Angelonia flowers are discussed. It was found that the flower colour patterns of bicoloured Angelonia hybrids are chimeral patterns as a consequence of histogenetic variation. This result was proven by light microscopy, double marking of tissues and ploidy analysis as well as somatic and generative segregation. Furthermore, the constitution of periclinal chimeras of bicoloured Angelonia hybrids was verified. Three new bicoloured Angelonia types including two cytochimeras resulted from colchicine treatment of axillary buds. These new types were histogenetically analysed. Thus, the first demonstration of a complete system of ploidy marked histogenetic variation in flower colour patterns is given.
Formation of Stable Chlorinated Hydrocarbons in Weathering Plant Material (2002)

Though several chlorinated organic compounds produced by humans are carcinogenic and toxic, some are also produced by the biotic and abiotic processes in the environment. In situ x-ray spectroscopy data indicate that natural organic matter in soils, sediments, and natural waters contain stable, less volatile organic compounds with chlorinated phenolic and aliphatic groups as the principal Cl forms. These compounds are formed at rapid rates from the transformation of inorganic Cl during humification of plant material and, thus, play a critical role in the cycling of Cl and of several major and trace elements in the environment and may influence human health.
The series connection of IGBTs with active voltage sharing (1997)

This paper presents the reasons that make series operation of insulated gate bipolar transistors (IGBTs) attractive and challenging and reviews the methods that may be used. Then, a new approach, which uses the IGBT's gate-controlled active regime in place of large voltage-sharing snubbers, is proposed. Analytical and simulation techniques are used to study the performance and conditions for stability given. It is concluded that when making each IGBT voltage follow a reference input, with closed-loop voltage control, the IGBTs are able to share the transient turn-off voltage without turn-off snubbers. This technique may lead to more compact and efficient high-voltage-power modules.
Novel gas turbine cycles with coal gasification (1979)

This paper summarizes the results of a study to devise efficient gas turbine cycles without steam bottoming for use with coal gasification. Substitution of other forms of heat recovery in place of steam bottoming offers a potential cost saving. A novel form of the intercooled-reheat-regenerative cycle was devised with thermal efficiency nearly as high as that of combined cycles. As an additional finding, a reference gasified coal combined cycle power plant with current technology gas turbines was shown to be potentially more efficient than current coal-fired steam power plants with flue gas desulfurization.
Building a portal for reusable software components with Microsoft SharePoint Server: design, implementation and experiences in Singapore (2003)

Reusability is an important concept in software development because it provides many benefits, including shorter development cycles, increased software reliability and lower production costs. This paper describes the experiences of developing a portal of reusable components to support information retrieval teaching and research in a Master’s programme in information studies at Nanyang Technological University in Singapore. The portal contains the source code of these components and covers a variety of areas in the field of information retrieval such as algorithms and data structures for lexical analysis, indexing and ranking. The portal provides users with features to search or browse for code, contribute new code under appropriate categories, participate in threaded discussions and rate source code. The portal also contains document management features that allow co‐ordinators to evaluate contributions before publishing them for general access.
Livelock avoidance for Meta-schedulers (2002)

Meta-scheduling, a process which allows a user to schedule a job across multiple sites, has a potential for livelock. Current systems avoid livelock by locking down resources at multiple sites and allowing a meta-scheduler to control the resources during the lock down period or by limiting job size to that which will fit on one site. The former approach leads to poor utilization; the later poses limitations on job size. This research uses BYU's Meta-scheduler (YMS) which allows jobs to be scheduled across multiple sites without the need for locking down the nodes. YMS avoids livelock through exponential back-off. This research quantifies the potential for livelock, determines a suitable back-off period, and provides a structure upon which to test theoretical local schedulers. The results show that livelock exists and that a suitable exponential back-off not only avoids livelock but reduces the scheduling time for each job.

Cis‐acting sequences that affect somatic hypermutation of Ig genes (1998)

We review our studies on the mechanism of somatic hypermutation of immunoglobulin genes. Most experiments were carried out using Ig transgenes. We showed in these experiments that all required cis-acting elements are present within the 10-16 kb of a transgene. Only the Ig variable region and its proximate flanks are mutated, not the constant region. Several Ig gene enhancers are permissive for somatic mutation. Association of the enhancer with its natural Ig promoter is not necessary. However, the mutation process seems specific for Ig genes. No mutations were found in housekeeping genes from cells with high levels of somatic hypermutation of their Ig genes. The Ig enhancers may provide the Ig gene specificity. An exception may be the BCL6 gene, which was mutated in human but not in mouse B cells. Transcription of a region is required for its mutability. When the transcriptional promoter located upstream of the variable region is duplicated upstream of the constant region, this region also becomes mutable. This suggests a model in which a mutator factor associates with the RNA polymerase at the promoter, travels with the polymerase during elongation, and causes mutations during polymerase pausing. The DNA repair systems, nucleotide excision repair and DNA mismatch repair, are not required. Our recent data with an artificial substrate of somatic mutation suggest that pausing may be due to secondary structure of the DNA or nascent RNA, and the specific mutations to preferences of the mutator factor.
