Stress Analysis of Unnotched C-Rings Used for Stress Cracking Studies (1968)

A technique for measuring elastic strains and the location between the plastically and elastically deformed portions of an unnotched C-ring sample is presented. Such C-rings when used to study sulfide stress cracking may incur cracks caused by both hydrogen embrittlement and stress corrosion cracking, whereas the presence of notches in the C-rings conceivably may force failure by only hydrogen embrittlement. Current studies by the authors on sulfide stress cracking include the use of both notched and unnotched C-rings.
Nonisothermal Vulcanization of Rubber Compounds (1988)

Abstract In the present paper, progress has been made in developing a model for nonisothermal vulcanization of rubber compounds. The model is presently based on differential scanning calorimetry (DSC) measurements of heat evolved during vulcanization. The model parameters are determined from several isothermal DSC scans including measurements of induction time and rate of vulcanization. This model has conveniently been employed for a calculation of the temperature distribution during vulcanization of a rubber slab based on a one-dimensional heat-conduction equation with a heat-generation term. The simulation allowed us to predict the dynamics of the development of the state of cure distribution in the rubber slabs. Predicted results from the vulcanization model have been verified with experimental data on induction time and rate of vulcanization from nonisothermal DSC scans and with measurements of the state of cure distribution in rubber slabs cured under different vulcanization conditions between two heated plates. Although this model is based on DSC data, the approach developed can easily be extended to similar curing data obtained by means of the modulus measurement technique.

In Vitro propagation and characterization of primary prostate tumor stem/progenitor cells (2009)

To better understand the underlying mechanism behind the recurrence of end-stage, androgen depletion independent prostate cancer (ADI), we have successfully characterized primary human prostate tumor cells in vitro. This thesis presents a reliable culture system that consistently propagates and maintains epithelial cultures taken directly from early-stage prostate adenocarcinomas. As a result of our methodology, we were able to put 70 prostate radical resection tissue samples into culture: 42 adenocarcinomas and 28 benign hyperplasias. All 42 early- stage cancers produced few (3-5) to many (400+) single epithelial colonies and expressed putative stem/progenitor cell markers CD44, integrin-\\[alpha\\]₂\\[Beta\\]₁, High MW CK 5/ 14, and CD133 along with embryonic transcription factors Oct4, Sox-2, and immortalization gene Bmi-1. Every proliferating colony possessed a naturally formed prostate stem cell niche, which supplied the highly epithelial prostate progenitors. These presumed stem cell niches, we termed "Stem Cell Centers" (SCC), stained positive for stem cell marker CD133. Senescence was observed in all cultures in later passages due to the loss of the necessary SCC. Our methodology is optimal for reliably growing out early-stage prostate tumor stem/progenitor cells - which is essential in the understanding of lethal ADI progression - and allows for the development of better therapies and treatments for this metastatic disease.

The evidence includes field, petro-graphic, and chemical data collected from studies of two stratigraphic sequences that contain red beds: (1) Recent, Pleistocene, and Pliocene deposits in the Sonoran desert of northeastern Baja California, Mexico, and (2) late Paleozoic deposits in Colorado.The sequence in the Sonoran desert contains examples of red beds forming today in a hot dry climate. They are associated with bedded evaporites and occur where regional faunal, floral, and pedological evidence indicates rainfall has been low throughout the postdepositional history of the sediments. The facies associations reflect deposition in fluvial and fluvial-marine transitional environments. Red arkose fanglomerates occur on the flanks of the highland source areas, and red muds, probably of intertidal and shallow subtidal origin, occur in the transition sediments. Both of these red-stained facies show progressive stages of in situ alteration of nonred sediments to hematite-stained red beds, and in each, the iron in the stain is derived from intra-stratal alteration of iron-bearing detrital grains, particularly iron silicates such as hornblende and bio-tite.The late Paleozoic red beds of Colorado contain rock types and facies associations similar to those of the Sonoran desert; they are interpreted as ancient counterparts of those red beds. Numerous lines of field and petrographic evidence indicate that the hematite pigment in the late Paleozoic red beds formed in place after the sediments were deposited in desert basins.

Wireless Andrew [mobile computing for university campus] (1999)

At Carnegie Mellon University in Pittsburgh, staff and students are using mobile computers for various tasks such as transferring lecture notes, sending e-mails, or surfing the net. This possible due to the installation of a wireless network which will cover all 28 academic and administrative buildings on the 40-hectare campus, and provide service to 10000 people. As long as they are on campus, the university community will be able to take advantage of the network. The high speed wireless infrastructure installed at Carnegie Mellon is called Wireless Andrew. Started as a National Science Foundation-funded research network to support Carnegie Mellon's wireless research initiative, the network originally provided coverage in seven campus buildings. The challenges in building such a large network are far from trivial. They include designing the network so that coverage blankets the entire campus, providing enough capacity to handle the campus-wide traffic load. Further, the network must provide highly reliable service. It builds on the university's wired network infrastructure, which currently provides 10-Mb/s and 100-Mb/s Ethernet service. To supply high-speed wireless service to the campus, Lucent WaveLAN equipment has been installed, which uses direct sequence spread-spectrum radio to provide a raw data rate of 2 Mb/s. For wireless access off campus or otherwise out of the range of the WaveLAN network, cellular digital packet data is used.
Depression in adduction syndrome. (1985)

Three cases of depression in adduction syndrome are described. All occurred unilaterally, in the left eye, in boys and were characterized by depression and retraction of the involved eye with attempted adduction. This was accompanied by an inability to elevate the eye in adduction and a markedly abnormal head posture. Surgery, consisting of superior oblique tenotomy and recession of the lateral rectus muscle, did not allow the ocular rotation to improve but did allow the anomalous head posture to be corrected. The homogeneity of the clinical appearance and the lack of response to surgery suggests that this is a distinct clinical entity.
Approximating the Permanent (1989)

A randomised approximation scheme for the permanent of a 0–1s presented. The task of estimating a permanent is reduced to that of almost uniformly generating perfect matchings in a graph; the latter is accomplished by simulating a Markov chain whose states are the matchings in the graph. For a wide class of 0–1 matrices the approximation scheme is fully-polynomial, i.e., runs in time polynomial in the size of the matrix and a parameter that controls the accuracy of the output. This class includes all dense matrices (those that contain sufficiently many 1's) and almost all sparse matrices in some reasonable probabilistic model for 0–1 matrices of given density. For the approach sketched above to be computationally efficient, the Markov chain must be rapidly mixing: informally, it must converge in a short time to its stationary distribution. A major portion of the paper is devoted to demonstrating that the matchings chain is rapidly mixing, apparently the first such result for a Markov chain with genuinely complex structure. The techniques used seem to have general applicability, and are applied again in the paper to validate a fully-polynomial randomised approximation scheme for the partition function of an arbitrary monomer-dimer system.
Metabolism of prostaglandins A1 and E1 in man. (1975)

To investigate the in vivo whole blood metabolic clearance rates and sites of metabolism of prostaglandins A1 and E1 in man, constant infusions of the tritiated compounds were administered to normal subjects and to patients undergoing cardiac catheterization. The whole blood metabolic clearance rate of [3H]prostaglandin A1 in eight men was 5,003 +/- 864 liters/day (SD) or 2,546 +/- 513 liters/day per m2 (SD). Nonradioactive prostaglandin A1 was similarly infused in two subjects, and the metabolic clearance rates were determined, utilizing a specific radioimmunoassay. The clearance rates with this method correlated closely with those determined by the isotope infusions. Extraction studies of prostaglandin A1 showed that pulmonary, splanchnic, renal, and extremity perfusions resulted in 8.1 +/- 4.1, 56.1 +/- 10.1, 50.3 +/- 3.4, and 34.4 +/- 5.9% (SEM) removal, respectively. With [3H]=prostaglandin E1, the whole blood metabolic clearance rate was determined from the pulmonary artery concentration in three patients and averaged 4,832 +/- 1,518 liters/day (SD) or 2,686 +/- 654 liters/day per m2 (SD). Pulmonary extraction was 67.8 +/- 6.8% (SEM) and extremity removal averaged 6.6 +/- 4.9% (SEM). These results indicate that A prostaglandins are metabolized by several organs, such as the liver and kidney, and possibly by intravascular pathways as well. In man, the E prostaglandins are primarily metabolized by the lung, but extraction is not complete and approximately one-third may escape lung metabolism. Thus, these findings suggest that both E and A prostaglandins in the venous circulation may reach the systemic circulation in man.
THE DEVELOPMENT OF AN OBJECT-ORIENTED SYSTEM WHICH INTEGRATES SIMULATION AND RECONSTRUCTION WITHIN A COMMON FRAMEWORK (1995)

A common problem for small experiments is that the design of the data acquisition, the simulation of the experiment and the reconstruction and analysis of real data is broken up into several disjoint development phases. Software development is necessary in all phases, yet continuity and an overall design strategy is lacking. This leads to duplication of software components and interface problems from one phase to the next and prohibits the generation of code which is reusable over the lifetime of many experiments. We address this problem within an object-oriented paradigm.
Enhancing Features of Cloud Computing Using Cloud Access Security Brokers to Avoid Data Breaches (2019)

Data breaches have gained widespread attention as businesses of all sizes become increasingly reliant on digital data, cloud computing, and workforce mobility. Cloud applications reduce costs and improve productivity. But it is equally important to monitor and protect data in a cloud environment. These are the questions that arise how to deal with lost visibility, unmanaged devices, and careless users. This paper explains how cloud access security brokers (CASBs) extend security to cloud applications, awareness for data breaches, providing visibility, threat protection, access control, and compliance. The key characteristics and benefits of cloud access security brokers (CASBs) are visibility, threat protection, access control and compliance are key components of this paper to extend data loss prevention (DLP). There is need to create the architecture of CABs having feature to deal with all types of Data Breaches. The result of the study provided a secure architecture to fulfill the security needs and tracks the complex connections between enterprise infrastructure and its cloud service provider.
The value of dicalcium phosphate, Vitamin A, and grinding sorghum grain for calves fed prairie hay (2011)

The 60 steer and heifer calves, six steers and four heifers per lot, used in this experiment, were good to choice grade Herefords from near Fort Davis, Texas, and were assigned on a random-weight basis to their treatments. All lots received all the prairie hay they would consume, 4 pounds of sorghum grain, and 1 pound of soybean meal per head daily. Where Vitamin A (10,000 I.U. daily) and dicalcium phosphate (0.1 pound per head daily) were fed they were mixed with the soybean meal. In the lots fed ground sorghum grain, it was ground medium fine.
Reusability-Based Strategy for Development of Information Systems: Implementation Experience of a Bank (1990)

This paper describes the experience of a large bank in designing and implementing an information systems strategy that is based on the concept of resuability. The design and implementation was performed in two stages: (1) building a prototype to investigate the feasibility and attractiveness of reusability concept for the bank; and (2) its subsequent implementation using a library of reusable entities and a programmer’s workbench. The implementation experience confirmed that applying the reusability concept to all stages of the system’s life cycle results in both strategic (e.g., improving programmer productivity and increasing the bank’s capacity for timely response to market opportunities) and operational (e.g., reducing and controlling system development and maintenance costs) benefits. It is estimated that the library of reusable entities embedded within the programmer workbench saved the bank over $1.5 million in development costs in 1989 alone. Two of the most important lessons learned in implementing the reusability-based strategy are: (1) reusability comes in many flavors and should be applied to all stages of systems life cycle; and (2) major challenges in implementing the reusability-based strategy are managerial, not technical.
Creating WFPC2 Dark Reference Files: Addendum (2001)

Carbon emission trading market promotes carbon emission reduction effectively. Accurate carbon price forecasting is crucial for relevant policy makers and investors. However, due to the non-linearity, uncertainty, and complexity of carbon prices, the current predication models fail to predict carbon prices accurately. In this paper, an advanced deep neural network model named TCN-Seq2Seq is proposed to forecast carbon prices. The novelty of the proposed model focuses on the "sequence to sequence" layout to learn temporal data dependencies using only fully convolutional layers. Being provided with parallel training for fewer parameters, TCN-Seq2Seq forecasting model is more suitable for small carbon price dataset in few-shot learning way. Qualitatively and quantitatively, we find that the proposed framework consistently and significantly outperforms traditional statistical forecasting models and state-of-the-art deep learning prediction model with respect to predictive ability and robustness. Particularly, our proposed model achieves forecasting accuracy with the highest DA value (0.9697), the lowest MAPE value (0.0027), and the lowest RMSE value (0.0149), showing superior prediction performance compared with the traditional statistical forecasting models. The accuracy of carbon price forecasting gives insight to policy makers and carbon market investors.
Objects of Relief (2013)

Peptide separation by capillary electrophoresis with ultraviolet detection: Some simple approaches to enhance detection sensitivity and resolution [(pemisahan peptida oleh elektroforesis rerambut dengan pengesan ultra-lembayung: Pendekatan mudah untuk meningkatkan isyarat pengesanan dan resolusi)] (2011)

Capillary electrophoresis (CE) is one of the leading separation technologies for analysis of water-soluble analytes. CE has many advantages over the more established methods such as liquid chromatography and gel electrophoresis particularly in rapid analysis, require very little sample, use less or no toxic organic solvent, high peak efficiency and ease of automation. Despite the many attractive advantages of CE, CE users continue to seek improvements particularly on detection sensitivity, resolution and selectivity. This paper presented several simple approaches to improve detection sensitivity using simple sample preconcentration called field-enhanced sample injection (FESI) and chromatographic-based ZipTip C 18 pre-concentrator. Also, some improvements in the resolution of complex peptides mixture when using two strategies namely, capillary coating and manipulation of the hydrophobicity of peptides using perfluorinated acids as background electrolyte (BGE), which have anionic conjugate base forms with hydrophobic character. As test compounds, standard peptide mixture and proteins digests were used for these studies. The results showed that FESI has significantly enhanced the detection signal of peptide standards and bovine serum albumin (BSA) tryptic digests. As for the use of ZipTip C 18 pre-concentrator, selective enhancement in detection signal was particularly notable on the late migrating peptides. Coating the capillary proved to have little changes on the CE of peptides when used in conjunction with acidic BGE. Electropherograms of BSA tryptic peptides in pentafluoropropionic acid (PFPA) and heptafluorobutyric acid (HFBA) showed interesting profile, with notable resolution improvement for peptides with close similarity in electrophoretic mobilities.
A closed-loop control for the power source of the ozonizer (2004)

In this paper, the load characteristic of the ozonizer is analyzed by theory and experiments. The curve of I-V-f is achieved. A high-frequency power source with closed loop control is designed based on the load characteristic of the ozonizer too. It has the advantage of good stability, high efficiency, small size, low noise etc. The view are confirmed by experimental results.
Lrp5 and Lrp6 play compensatory roles in mouse intestinal development (2011)

Low-density lipoprotein receptor-related proteins 5 and 6 (Lrp5 and Lrp6) are co-receptors of Wnt ligands and play important roles in Wnt/β-catenin signal transduction. Mice homozygous for a germline deletion of Lrp6 die at birth with several associated defects, while Lrp5-deficient mice are viable. Here, we conditionally deleted Lrp5 and/or Lrp6 in the mouse gut ((gut-/-)) by crossing mice carrying floxed alleles of Lrp5 and Lrp6 to a strain expressing Cre recombinase from the villin promoter (villin-Cre). The changes in morphology, differentiation, and Wnt signal transduction were validated using immunohistochemistry and other staining. Consistent with observations in mice carrying a homozygous germline deletion in Lrp5, intestinal development in Lrp5(gut-/-) mice was normal. In addition, mice homozygous for villin-Cre-induced deletion of Lrp6 (Lrp6(gut-/-)) were viable with apparently normal intestinal differentiation and function. However, mice homozygous for villin-Cre inactivated alleles of both genes (Lrp5(gut-/-) ; Lrp6(gut-/-)) died within 1 day of birth. Analysis of embryonic Lrp5(gut-/-); Lrp6(gut-/-) intestinal epithelium showed a progressive loss of cells, an absence of proliferation, and a premature differentiation of crypt stem/precursor cells; no notable change in differentiation was observed in the embryos lacking either gene alone. Further immunohistochemical studies showed that expression of the Wnt/β-catenin target, cyclin D1, was specifically reduced in the intestinal epithelium of Lrp5(gut-/-); Lrp6(gut-/-) embryos. Our data demonstrate that Lrp5 and Lrp6 play redundant roles in intestinal epithelium development, and that Lrp5/6 might regulate intestinal stem/precursor cell maintenance by regulating Wnt/β-catenin signaling.
Direct Position Analysis of the 4–6 Stewart Platforms (1994)

Although Stewart platforms have been applied in the design of aircraft and vehicle simulators and parallel robots for many years, the closed-form solution of direct (forward) position analysis of Stewart platforms has not been completely solved. Up to the present time, only the relatively simple Stewart platforms have been analyzed. Examples are the octahedral, the 3–6 and the 4–4 Stewart platforms, of which the forward position solutions were derived as an eighth or a twelfth degree polynomials with one variable in the form of square of a tan-half-angle. This paper further extends the direct position analysis to a more general case of the Stewart platform, the 4–6 Stewart platforms, in which two pairs of the upper joint centers of adjacent limbs are coincident. The result is a sixteenth degree polynomial in the square of a tan-half-angle, which indicates that a maximum of 32 configurations may be obtained. It is also shown that the previously derived solutions of the 3–6 and 4–4 Stewart platforms can be easily deduced from the sixteenth degree polynomial by setting some geometric parameters be equal to 1 or 0.
