Synthesis of Chemically Stabilized Cristobalite (1992)

The synthesis of chemically stabilized cristobalite (CSC) by a wet‐chemical route is described. CSC is a form of silica (containing small amounts of other oxides) which is similar in many ways to β‐cristobalite, but does not invert to α‐cristobalite upon cooling. The effects of changing the dopant levels and various synthetic parameters on the phases formed in the CaO‐Al 2 O 3 ‐SiO 2 system have been investigated. Stabilization of cristobalite with a number of different dopant combinations has been attempted, with mixed results. The use of wet‐chemical techniques has led to the synthesis of apparently phase‐pure CSC in a composition region where traditional solid‐state synthetic techniques yield a mixture of other phases.

Increasing Efficiency of Template-Matching Algorithm using Binary-Image instead of Color-Image (2014)

Abstract- Template matching algorithms uses color-images most of time, but it is not necessity. They sometimes find shapes in particular images. So use of binary-images has been proposed instead of color-images. As binary-image have all information related to shape same as in color-image, only color information is dropped. Binary-image is smaller in size than color-image, which make storage and transmission more efficient as well as makes processing faster [4]. Some application of template matching where time is first concern than use of color-images may lead us to delay. Here use of binary-image as an input to template matching algorithms has been proposed, where identifying particular shape is more important. Omitting color information from image makes image more efficient for processing, storage and transmission.

Investigation of the amorphous-to-crystalline transition in Mo/Si multilayers (2001)

The microstructure of Mo/Si multilayers grown by magnetron and ion beam sputter deposition has been characterized over a range of Mo layer thicknesses. We observe an abrupt amorphous-to-crystalline transition in the Mo layers at a thickness of ∼2 nm. The transition exhibits several interesting features including a large decrease in the thickness of the Si-on-Mo interlayer and a significant increase in the roughness of the multilayer. We present an explanation for the transition behavior in terms of a critical thickness for the nucleation of Mo crystallites.

Scaling Hard Vertical Surfaces with Compliant Microspine Arrays (2006)

A new approach for climbing hard vertical surfaces has been developed that allows a robot to scale concrete, stucco, brick and masonry walls without using suction or adhesives.The approach is inspired by the mechanisms observed in some climbing insects and spiders and involves arrays of microspines that catch on surface asperities. The arrays are located on the toes of the robot and consist of a tuned, multi-link compliant suspension. The fundamental issues of spine allometric scaling versus surface roughness are discussed and the interaction between spines and surfaces is modeled. The toe suspension properties needed to maximize the probability that each spine will find a useable surface irregularity and to distribute climbing loads among many spines are detailed. The principles are demonstrated with a new climbing robot, SpinybotII, that can scale a wide range of flat exterior walls, carry a payload equal to its own weight, and cling without consuming power. The paper also reports how toe parameters scale with robot mass and how spines have also been used successfully on the larger RiSE robot.

Postgenital Carpel Fusion in Catharanthus roseus (Apocynaceae) IV. Significance of the Fusion (1978)

The ontogenetic and phylogenetic significances of the postgenital carpel fusion in Catharanthus roseus were investigated experimentally. When one of the two carpel primordia was surgically destroyed prior to carpel fusion, the remaining carpel differentiated nevertheless; however, the tissue development on the adaxial (normally fused) carpel face appeared aberrant. Possible reasons for this modified ontogeny are discussed. The suggestion that syncarpy is phylogenetically significant because any pollen tube can potentially reach any ovule was verified in C. roseus by monitoring pollen tube growth following spatially controlled pollinations. The suture formed by the postgenital fusion was no barrier to pollen tube growth, and the pollen tubes rapidly became distributed throughout the stigmatic tissue.

Integrating usability engineering and agile software development: A literature review (2010)

The various agile software development methodologies have promoted since their inception and even demanded high degree to improve the quality of the software product. Usability engineering has made its way into the software mainstream and has caught the attention of software engineers and researchers worldwide due to rapidly growing and volatile internet software industry, despite their different perspectives on creating software both have a major role in making good software. Usability focuses on how the end users will work with the software and agile development focuses on how the software should be developed. The way these two perspectives are being combined in practice is still not well understood. This study is a preliminary literature review that describes the key question that how usability-engineering practices should be integrated with agile software development in order to make stronger and effective usable software system. This paper focuses on identifying the tensions between usability and agile methods. The research aim is to identify the common approach of agile methods and usability engineering by surveying extensive related work on integration of usability and agile methods.

Anabolic Effects of Human Biosynthetic Parathyroid Hormone Fragment (1–34), LY333334, on Remodeling and Mechanical Properties of Cortical Bone in Rabbits (1999)

Intermittent administration of parathyroid hormone (PTH) has an anabolic effect in cancellous bone of osteoporotic humans. However, the effect of PTH on cortical bone with Haversian remodeling remains controversial. The aim of this study was to determine the effects of biosynthetic human PTH(1-34) on the histology and mechanical properties of cortical bone in rabbits, which exhibit Haversian remodeling. Mature New Zealand white rabbits were treated with once daily injections of vehicle, or PTH(1-34), LY333334, at 10 micrograms/kg/day or 40 micrograms/kg/day for 140 days. Body weight in rabbits treated with PTH did not change significantly over the experimental period. Serum calcium and phosphate were within the normal range, but a 1 mg/ml increase in serum calcium was observed in rabbits given the higher dose of PTH. Histomorphometry of cortical bone in the midshaft of the tibia showed significant increases in periosteal and endocortical bone formation in these rabbits. Intracortical bone remodeling in the tibia was activated and cortical porosity increased by PTH. Cross-sectional bone area and bone mass of the midshaft of the femur increased significantly after PTH treatment. Ultimate force, stiffness, and work to failure of the midshaft of the femur of rabbits given the 40 micrograms dose of PTH were significantly greater than those in the control group, whereas elastic modulus was significantly lower than that in the rabbits given the 10 micrograms dose of PTH, but not different from controls. In the third lumbar vertebra, PTH increased both formation and resorption without increasing cancellous bone volume. The increases in bone turnover and cortical porosity were accompanied by concurrent increases in bone at the periosteal and endocortical surfaces. The combination of these phenomena resulted in an enhancement of the ultimate stress, stiffness, and work to failure of the femur.
Rechentafeln (1940)

Zur graphischen Ausführung von Multiplikationen und Divisionen sind zwei Fluchtlinientafeln 1 a und 1 b wiedergegeben. Sie sollen demjenigen Benutzer der Tafeln, der keinen Rechenschieber zur Hand hat, diese Rechnungen erleichtern. Die gewöhnliche Fluchtlinientafel für Multiplikation und Division (Tafel 1a) ist zwar übersichtlich und bequem zu benutzen, besitzt aber keine hohe Genauigkeit. Um auch genauere Rechnungen zu ermöglichen, wurde Tafel 1 b eingefügt, welche zwar eine etwas komplizierte Ablesungsvorschrift benötigt, in ihrer Genauigkeit aber einem 25 cm langen Rechenschieber nur wenig nachsteht.

Optimizing clinical trial supply requirements: simulation of computer-controlled supply chain management (2004)

We conclude that a computer-controlled supply chain enables medication savings to be realized and that it is possible to quantify the distribution of these savings using a simulation model. The simulation model can be used to optimize the prestudy medication supply strategy and for midstudy monitoring using real-time data contained in the study database.
Herbimycin A blocks IL‐1‐induced NF‐κB DNA‐binding activity in lymphoid cell lines (1992)

The mechanism by which interleukin-1 alpha (IL-1 alpha) activates NF-kappa B DNA-binding activity is not completely understood. While it is well established that protein kinase C can activate NF-kappa B, neither protein kinase C nor protein kinase A appears to be critical in the induction of NF-kappa B by IL-1 alpha. Since a number of growth factors signal via protein tyrosine kinase, in this study we examined a possible involvement of protein tyrosine kinase in the IL-1 alpha-induced NF-kappa B. The results showed that in the murine pre-B cell line 70Z/3 and in the murine T cell line EL-4 6.1 C10 IL-1 alpha-induced NF-kappa B was associated with transient increase in protein tyrosine kinase activity. Pre-treatment of these cell lines with herbimycin A, an inhibitor of tyrosine kinase activity, blocked the IL-1 alpha-enhanced protein tyrosine kinase activity and the IL-1 alpha-induced NF-kappa B DNA-binding activity. Herbimycin A at concentrations sufficient to block IL-1 alpha-induced NF-kappa B did not block the phorbol 12-myristate 13-acetate (PMA)-induced NF-kappa B. The data suggest that IL-1 alpha and PMA activate NF-kappa B by different pathways and that induction of NF-kappa B DNA-binding activity by IL-1 might be dependent on protein tyrosine phosphorylation.
Gain of survival signaling by down-regulation of three key miRNAs in brain of calorie-restricted mice (2011)

The decline in cognitive robustness with aging can be attributed to complex genetic pathways involving many cellular dysfunctions, cumulative over time, precipitating in frailty and loss of wellness in the elderly brain. The size and health of the neuronal cell population determines cognitive robustness in mammals. A transgenic mouse model over-expressing Bcl-2 has been shown to rescue neurons from naturally occurring cell death (NOCD). Here we show that in the brain of calorie-restricted (CR) mice, there is an age-dependent decreased expression of microRNAs mmu-miR-181a-1*, mmu-miR-30e and mmu-miR-34a, with a corresponding gain in Bcl-2 expression, and decreases in pro-apoptosis genes such as Bax and cleavage of Caspases. Functional characterization shows that these miRNAs repress Bcl-2 expression by the 3'UTR reporter assays, accompanied by loss of this gene's endogenous expression, and a gain in pro-apoptosome-specific proteins. Over-expression of these miRNAs increases the rate of apoptosis, accompanied by a decline in Bcl-2 expression in miRNA-transfected mouse and human cell lines. We report here that down-regulation of miR-34a, -30e, and -181a permits their shared target gene expression (Bcl-2) to remain at a high level without post-transcriptional repression, accompanied by concomitant low levels of Bax expression and Caspase cleaving; this chain event may be a part of the underlying mechanism contributing to the gain in neuronal survival in long-lived CR-fed mice.
Bistable State of Protons for Low-Voltage Memories (2020)

Molecular ferroelectrics are attracting tremendous interest because of their easy and environmental-friendly processing, low acoustic impedance, and mechanical flexibility. Their ferroelectric mechanism is mainly ascribed to the order-disorder transition of molecules such as spherical 1,4-diazabicyclo[2.2.2] octane (DABCO) and quinuclidine. Here, we present two molecular ferroelectrics, [HDABCO][TFSA] and its deuterated one [DDABCO][TFSA] (TFSA = bis(trifluoromethylsulfonyl)ammonium), whose ferroelectricity is triggered by the proton ordering. This is the first time that the protons show a thermally fluctuated bistability with a double-well potential in DABCO-based ferroelectrics. A large deuterium isotope effect (Δ<i>T</i> = ∼53 K) not only proves that they are hydrogen-bonded ferroelectrics but also extends the ferroelectric working temperature range to room temperature. The superfast polarization switching of 100 kHz and ultralow coercive voltage of 1 V (far less than 5 V required for commercially available ferroelectric devices), benefiting from the low energy for proton transfer, allow [DDABCO][TFSA] a great potential for memory devices with low-voltage, high-speed operation. This work should inspire further exploration of hydrogen-bonded molecular ferroelectrics for flexible and wearable devices with the low-power information storage.

This paper documents recent developments in the field of GPS travel surveying and ways in which GPS has been incorporated into or even replaced traditional household travel survey methods. A new household activity survey is presented which uses automated data reduction methods to determine activity and travel locations based on a series of heuristics developed from land-use data and travel characteristics. The algorithms are used in an internet-based prompted recall survey which utilizes advanced learning algorithms to reduce the burden placed on survey respondents. Initial results of a small pilot study are discussed and potential areas of future work are presented.Keywords: Global Positioning SystemSurvey MethodsLearning AlgorithmsTravel SurveyTravel BehaviorPrompted Recall
Optical waveguide microscopy (1990)

Optical waveguide microscopy is introduced as a novel imaging technique that allows for the microscopic characterization of thin-film samples by using guided optical waves as illumination light source. Excellent thickness (&lt;1 nm) and good lateral resolution (&lt;10 μm) is demonstrated. As a first application we image and analyze the two-dimensional thickness profile of a planar polymeric spun-on waveguide structure.
Exploring chaotic motion through periodic orbits (1987)

The fractal invariant measure of chaotic strange attractors can be approximated systematically by the set of unstable n-periodic orbits of increasing n. Algorithms for extracting the periodic orbits from a chaotic time series and for calculating their stabilities are presented. With this information alone, important properties like the topological entropy and the Hausdorff dimension can be calculated.
Neuron‐Like Tubular Membranes Made of Diblock Copolymer Amphiphiles (2006)

Implications for the nervous system: The formation of polymeric myelin structures was studied at the copolymer/water interface and then elaborated in a dispersed phase. Sun-like structures formed with a complex multilamellar core and a corona made of short myelins. Myelin growth is solvent-promoted, in a strong analogy to natural myelins, which have membranes with a higher proportion of fluidizing molecules such as cholesterol.
Electrically Insulating Thermal Nano-Oils Using 2D Fillers (2012)

Different nanoscale fillers have been used to create composite fluids for applications such as thermal management. The ever increasing thermal loads in applications now require advanced operational fluids, for example, high thermal conductivity dielectric oils in transformers. These oils require excellent filler dispersion, high thermal conduction, but also electrical insulation. Such thermal oils that conform to this thermal/electrical requirement, and yet remain in highly suspended stable state, have not yet been synthesized. We report here the synthesis and characterization of stable high thermal conductivity Newtonian nanofluids using exfoliated layers of hexagonal boron nitride in oil without compromising its electrically insulating property. Two-dimensional nanosheets of hexagonal boron nitride are liquid exfoliated in isopropyl alcohol and redispersed in mineral oil, used as standard transformer oil, forming stable nanosuspensions with high shelf life. A high electrical resistivity, even higher than that of the base oil, is maintained for the nano-oil containing small weight fraction of the filler (0.01 wt %), whereas the thermal conductivity was enhanced. The low dissipation factor and high pour point for this nano-oil suggests several applications in thermal management.
