Adaptive robotic visual tracking: theory and experiments (1993)

The use of a vision sensor in the feedback loop is addressed within the controlled active vision framework. Algorithms are proposed for the solution of the robotic (eye-in-hand configuration) visual tracking and servoing problem. Visual tracking is stated as a problem of combining control with computer vision. The sum-of-squared differences optical flow is used to compute the vector of discrete displacements. The displacements are fed to an adaptive controller (self-tuning regulator) that creates commands for a robot control system. The procedure is based on the online estimation of the relative distance of the target from the camera, but only partial knowledge of the relative distance is required, obviating the need for offline calibration. Three different adaptive control schemes have been implemented, both in simulation and in experiments. The computational complexity and the experimental results demonstrate that the proposed algorithms can be implemented in real time.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Sentience System Computer: principles and practices (2003)

Research on artificial intelligence and sensitivity control technology has progressed in recent years, and the technology of imitating human thinking, feeling, and sensitivity have been established. However, research on Sentience as the way of idea generation and intuition that are the origin of human being's intellectual production activity seems to have just started. Moreover, although the field of quantum computing is also being researched briskly, no practical results have been produced yet. In this paper, a new machine called Sentience System Computer (SSC) is presented. SSC is an intuition computer system having self-intention. According to the interpretation in the many-worlds quantum theory, the spontaneous intuition of the human can be defined as what is produced by interference from the self multiple worlds which are resulted from all piles of self-history. We present the principles and practices of SSC, the basic spontaneity type algorithm. When applying SSC to the sensitivity control technique, the process of generating sentience, the procedure of human conception, the state of the idea database and some recent results of SSC, are given also.

Will the ‘Good Fairies’ Please Prove to us that Vitamin E Lessens Human Degenerative Disease? (1997)

Recent research about the role of free radical derivatives of oxygen and nitrogen in biological systems has highlighted the possibility that antioxidants, such as vitamin E, that prevent these processes in vitro may be capable of carrying out a similar function in living organisms in vivo. There is increasing evidence that free radical reactions are involved in the early stages, or sometimes later on, in the development of human diseases, and it is therefore of particular interest to inquire whether vitamin E and other antioxidants, which are found in the human diets, may be capable of lowering the incidence of these diseases. Put simply, the proposition is that by improving human diets by increasing the quantity in them of antioxidants, it might be possible to reduce the incidence of a number of degenerative diseases. Of particular significance to these considerations is the likely role of the primary fat-soluble dietary antioxidant vitamin E in the prevention of degenerative diseases such as arteriosclerosis, which is frequently the cause of consequent heart attacks or stroke, and prevention of certain forms of cancer, as well as several other diseases. Substantial evidence for this proposition now exists, and this review is an attempt to give a brief account of the present position. Two kinds of evidence exist; on the one hand there is very substantial basic science evidence which indicates an involvement of free radical events, and a preventive role for vitamin E, in the development of human disease processes. On the other hand, there is also a large body of human epidemiological evidence which suggests that incidence of these diseases is lowered in populations having a high level of antioxidants, such as vitamin E, in their diet, or who have taken steps to enhance their level of intake of the vitamin by taking dietary supplements. There is also some evidence which suggests that intervention with dietary supplements of vitamin E can result in a lowered risk of disease, in particular of cardiovascular disease, which is a major killer disease among the developed nations of the world. The intense interest in this subject recently has as its objective the possibility that, by making some simple alterations to dietary lifestyle, or by enhancing the intake of vitamin E by fortification of foods, or by dietary supplements, it may be possible to reduce substantially the risk of a large amount of common, highly disabling human disease. By this simple means, therefore it may be possible to improve substantially the quality of human life, in particular for people of advancing years.
Induction of NO and prostaglandin E<sub>2</sub>in osteoblasts by wall-shear stress but not mechanical strain (1997)

The nature of the stimulus sensed by bone cells during mechanical usage has not yet been determined. Because nitric oxide (NO) and prostaglandin (PG) production appear to be essential early responses to mechanical stimulation in vivo, we used their production to compare the responsiveness of bone cells to strain and fluid flow in vitro. Cells were incubated on polystyrene film and subjected to unidirectional linear strains in the range 500-5,000 microstrain (microepsilon). We found no increase in NO or PGE2 production after loading of rat calvarial or long bone cells, MC3T3-E1, UMR-106-01, or ROS 17/2.8 cells. In contrast, exposure of osteoblastic cells to increased fluid flow induced both PGE2 and NO production. Production was rapidly induced by wall-shear stresses of 148 dyn/cm2 and was observed in all the osteoblastic populations used but not in rat skin fibroblasts. Fluid flow appeared to act through an increase in wall-shear stress. These data suggest that mechanical loading of bone is sensed by osteoblastic cells through fluid flow-mediated wall-shear stress rather than by mechanical strain.

Theoretical and experimental determination of sensitivity and edge enhancement in xeroradiography and ionography (1980)

A study of the factors affecting image quality and x-ray sensitivity of ionography and xeroradiography is presented. First, the relative charge sensitivities (nC/cm2mR) are compared. It is shown that high pressure xenon (10 atm cm) as used in ionography produces more than 2.5--3.5 times more charge than the selenium layers used in xeroradiography for the same x-ray exposure. The influence of development time and toner deposition on the appearance of images is investigated theoretically and experimentally. A parameter describing development sensitivity is proposed. It is shown that an increase in development sensitivity (ODcm2/nC) with increasing development time is accompanied by a loss in edge enhancement. The development sensitivity of ionography is about twice that typical of xeroradiography. This makes the total sensitivity (OD/mR) or the ionography process more than 4.5--6.5 times that of xeroradiography. The total sensitivity of ionography is about 1/2 that of par speed film screen combinations.
Scalable virtual machine storage using local disks (2010)

In virtualized data centers, storage systems have traditionally been treated as black boxes administered separately from the compute nodes. Direct-attached storage is often left unused, to not have VM availabilty depend on individual hosts. Our work aims to integrate storage and compute, addressing the fundamental limitations of contemporary centralized storage solutions. We are building Lithium, a distributed storage system designed specifically for virtualization workloads running in large-scale data centers and clouds. Lithium aims to be scalable, highly available, and compatible with commodity hardware and existing application software. The design of Lithium borrows techniques from Byzantine Fault Tolerance, stream processing, and distributed version control software, and demonstrates their practical applicability to the performance-sensitive task of virtual machine storage
Antibody Responses after Immunization with Killed Oral Cholera Vaccines during the 1985 Vaccine Field Trial in Bangladesh (1991)

Sera collected during the 1985 oral cholera vaccine trial in Matlab, Bangladesh, which demonstrated efficacy of a whole cell combined with cholera B subunit vaccine (WC/BS) and a whole cell only vaccine (WC), were analyzed for antitoxin and vibriocidal antibodies. Before vaccines were given, antitoxin titers were highest in children, especially those with O blood group, whereas vibriocidal titers rose throughout life. Two weeks after three doses of vaccine, geometric mean antitoxin titers were 2.5-4.5 times higher in vaccinees who received the WC/BS vaccine; the vibriocidal titers were 1.3-2.1 times higher in vaccinees who received either vaccine. The titer elevations were relatively brief and were barely detectable 7 months after the third dose even though significant levels of protection persisted greater than or equal to 3 years. Thus, the oral vaccines induced a serum response in this large field trial that was similar to that seen in earlier pilot studies, but the duration of the serum responses was much shorter than the duration of the protection.
How to benchmark RDF engines and not die trying. (2010)

Abstract. Existing RDF engines have developed optimization techniques and efficient physical operators that speed up execution time. Additionally, some of these approaches have implemented structures to efficiently store and access RDF data, and have developed execution strategies able to reuse data previously stored in cache. In order to study the benefits of the techniques offered by each approach, particular datasets have to be considered as well as different benchmarks of queries. Queries must be of different complexity, number of patterns, selectivity and shape, while datasets have to be of different sizes and correlations between subjects, predicates and objects. In this paper, we describe the benchmarks that we have developed to analyze the performance of existing RDF engines when creating and indexing RDF structures, as well as the quality of the optimization and execution strategies implemented by these engines.

Carcinogenicity of Epoxides, Lactones, and Peroxy Compounds. IV. Tumor Response in Epithelial and Connective Tissue in Mice and Rats<xref ref-type="fn" rid="FN2">2</xref> (1966)

The carcinogenic potencies of a series of alkylating and peroxy compounds were compared by the use of various routes of administration in mice and rats. Twelve of these compounds, earlier tested on mouse skin, were tested by one or more of the following routes: subcutaneous injection in mice and rats and intragastric feeding in rats. These experiments showed that those compounds tumorigenic to mouse skin are also active by other routes. These compounds are: β-propiolactone, β-butyrolactone, <it>d,l</it>-diepoxybutane, glycidaldehyde, and 1,2,5,6-diepoxyhexane. Those compounds inactive on mouse skin are weakly active or inactive by other routes. These compounds are: cumene hydroperoxide, 9,10-epoxy-stearic acid, diketene, 2,2,4-trimethylhydroxypentenoic acid-β-lactone, cyclohexenehydroperoxide, and lauroyl peroxide. β-Propiolactone and β-butyrolactone are mouse-skin carcinogens and induce gastric cancers when fed repeatedly to rats; however, 3 epoxides carcinogenic to mouse skin (glycidaldehyde, <it>d,l</it>-diepoxybutane, and 1-ethyleneoxy-3,4-epoxy cyclohexane) do not induce gastric cancers in rats. This finding is related to the rapid acid-catalyzed hydrolysis of epoxides in the rat stomach. The compounds tested induced tumors mainly at the site of application and did not give any significant incidence of tumors at sites distant from the site of application. These experiments indicate that connective tissue of rats is not unusually sensitive to tumor induction by these compounds and that subcutaneous injection in the rat is a useful system for the evaluation of potential carcinogens.

Total synthesis of bovine pancreatic ribonuclease A. Part 5. Synthesis of the protected S-protein (positions 21–124) and the protected S-peptide (positions 1–20) (1981)

Starting from the protected tetraoctacontapeptide corresponding to the sequence Z(OMe)-(41–124)-OBzl of bovine pancreatic RNase, the protected S-protein Z(OMe)-(RNase 21–124)-OBzl was synthesized by six successive azide condensations of the peptide fragments Z(OMe)-Asp(OBzl)-Arg(MBS)-Cys(MBzl)-NHNH-Troc (23), Z(OMe)-Arg(MBS)-Asn-Leu-Thr-Lys(Z)-NHNH2(24), Z(OMe)-Met(O)-Lys(Z)-Ser-NHNH2(25), Z(OMe)-Asn-Gln-Met(O)-NHNH2(26), Z(OMe)-Asn-Tyr-Cys(MBzl)-NHNH2(27), and Z(OMe)-Ser-Ser-Ser-NHNH2(28). In addition, the S-peptide was synthesized in a protected form, Z-Lys(Z)-Glu(OBut)-Thr-Ala-Ala-Ala-Lys(Z)-Phe-Glu(OBzl)-Arg(MBS)-Gln-His-Met(O)-Asp-Ser-Ser-Thr-Ser-Ala-Ala-NHNH2, by assembling three sub-units: (A)(14–20), (B)(9–13), and (C)(1–8).
Decision Support System for Cotton Bales Blending Using Genetic Algorithm (2010)

Traditionally the commercial value of cotton is accessed on the basis of subjective grading. The grade of cotton is decided on the basis of color, trash and ginning preparation, staple length and strength. Characteristics like length variation, fineness and maturity are also taken into account. [14] It is necessary for the cotton spinning mills to produce good quality yarn and that too at a competitive price. The cost and quality of yarn is greatly dependent on the cost and quality of cotton. So, wise selection of cotton and control on the cost at different stages of spinning, weaving, processing and marketing is very essential. It is a common practice in textile mills to mix cottons of different varieties. Hence, it is imperative to select the right cottons for the same, since it is one of the major factors affecting the total yarn cost as well as the final yarn quality.
Characteristics of Precipitation Systems Analyzed from Radar Data over Bangladesh (2005)

At present, a low-dense rain-gauge network over Bangladesh is the only tool by which to measure rainfall, so there is no way of understanding the properties of the precipitation systems occurring there. To obtain precise rainfall distributions and to clarify the characteristics of precipitation systems, radar data from the Bangladesh Meteorological Department (BMD) were used in the first investigation in Bangladesh. The BMD radar collects rain status data in six ranges. The precipitation rate was retrieved from the rain status obtained from BMD radar data. Correlation between three-days-running averaged rainfall estimated by radar and rain-gauges ranged from 0.63-0.89 over the months of 2000. The radar data was systematically underestimated by about one-fourth the rain-gauge value. Small size (～80 km 2 ) echoes contribute greatly to the total precipitation, but there were few large size echoes. The distribution of precipitation over Bangladesh obtained from radar data shows heavy precipitation in the northeast and southeast of the country, which is consistent with the rain-gauge rainfall data. Using the radar data characteristics of 185 analyzed convective systems, the development location, lifetime, shape, size, propagation speed, and direction were identified. The BMD radar data coverage (600km×600km) is divided into 3-regions: Northern, Central, and Southern, each being 600km east to west and 200km north to south. In general, precipitation systems develop in the Northern region and tend to move eastward. Precipitation system development in the Central and Southern regions is significant during the peak-monsoon months (June-August). Analysis of the radar data shows that the average time of maximum precipitation in the Northern region is 00-06 LST, in the Central region 06 LST and 15-18 LST, and in the Southern region 06-09 LST. The average lifetime of these systems is ～5.7 hours. Movement speed is ～5 ms -1
Pharmacokinetics, thrombogenicity and safety of a double viral inactivated factor IX concentrate compared with a prothrombin complex concentrate (2005)

Therapeutic options for developing countries have to assure an optimum safety and efficacy and low-cost antihaemophilic concentrates. A single blind randomized crossover study was carried out in 12 previously treated HB patients, comparing the pharmacokinetics (PK), thrombogenicity (TG) and safety of two plasma-derived double-inactivated (solvent/detergent heating at 100 degrees C, 30 min) factor IX (FIX) concentrates, UMAN COMPLEX DI (product A) [plasma-derived prothrombin concentrates (PCC)] and a high purity FIX concentrate AIMAFIX DI (product B, HPFIX). In a non-bleeding state, they received one single intravenous dose 50 IU FIX kg(-1) of PCC or HPFIX, and after a wash-out period of 14 days, the other product. We evaluated acute tolerance and determined PK parameters based on FIX levels measured over a 50 h postinfusion period. We studied fibrinogen, platelets, antithrombin, F1 + 2, TAT, D-dimer, over a 360 min postinfusion period. Ten cases remained in on-demand treatment for 6 months, five with PCC and five with HPFIX. PK and anti-FIX inhibitors were repeated at 3 and 6 months. No inhibitors were detected. PK values (PCC vs. HPFIX): clearence (CL; mL h(-1) kg(-1)) 5.2 +/- 1.4 vs. 6.5 +/- 1.4; the volume of distribution at steady state (mL kg(-1)) 154.9 +/- 54.9 vs. 197.5 +/- 72.5; mean residence time (h) 29.7 +/- 8.1 vs. 30.7 +/- 9.2; T(1/2) (h) 22.3 +/- 7 vs. 23.5 +/- 12.3; incremental recovery (IR; U dL(-1) U(-1) kg(-1)) 0.96 +/- 0.17 vs. 0.76 +/- 0.13. HPFIX showed significant lower IR and higher CL. There were no differences in PK at 3 and 6 months. In TG, significant increments in TAT and F1 + 2 at 30 min and 6 h were found with PCC. Product B PK results agrees with reported results for other HPFIX preparations. Use of PCC product A has to consider its thrombogenic activity.
