Development of a novel cloud-based multi-tenant model creation scheme for machine tools (2015)

In this paper, a novel private cloud-based multi-tenant model creation (MC) scheme, called CMTMCS, for machine tools is developed. The CMTMCS can simultaneously support multiple users from different tenants to create prediction models, while having higher usage rates of virtual machines and being more cost-effective, compared to an existing cloud-based model creation mechanism.
Role of “diseased” root cementum in healing following treatment of periodontal disease (1988)

This clinical trial was undertaken to examine whether root debridement in the treatment of periodontal disease must include the removal of the exposed cementum in order to achieve periodontal health. The study included 11 adult patients with moderate to advanced periodontal disease. In a split-mouth design, the dentition of each patient was by random selection divided into test- and control quadrants comprising the incisors, canines and premolars. Following a baseline examination, all patients were given a case presentation and a detailed instruction in self-performed oral hygiene measures. The patients were then subjected to periodontal surgery. Following reverse bevel incisions, buccal and lingual mucoperiosteal flaps were elevated and all granulation tissue was removed. In 2 jaw quadrants (control quadrants) in each patient, the denuded root surfaces were carefully scaled and planed in order to remove soft and hard deposits as well as all cementum, using hand instruments and flame-formed diamond stones. In the contralateral quadrants (test quadrants) the roots were not scaled and planed but soft microbial deposits were removed by polishing the root surfaces with the but soft microbial deposits were removed by polishing the root surfaces with the use of rubber cups, interdental rubber tips and a polishing paste. Calculus in the test quadrants was removed by the use of a curette, but precaution was taken to avoid the removal of cementum. The flaps were repositioned to their original level and sutured. The patients were following active treatment enrolled in a supervised maintenance care program including "professional tooth cleaning" once every 2 weeks for a 3-month period.(ABSTRACT TRUNCATED AT 250 WORDS)
[Clinical observation on effect of step respiration exercise combined Chinese drug therapy in treating pulmonary heart disease and exploration on its therapeutic mechanism]. (1999)

Respiration activity has definite influence on cardiovascular function of patients. SRE can significantly lower the heart rate, reduce the afterload, increase the pressure on coronary orifice by raising arterial diastolic pressure, enhance stroke output and alleviate the work of the heart. CDT can enhance the effect of SRE by synergetically removing pathogens to liberate the Lung, arresting the reversed Qi flow to remove Phlegm and relieve asthma, and replenishing the Kidney to control the reversed Qi.
Efficient TCAM Encoding Schemes for Packet Classification Using Gray Code (2007)

Packet classification is an enabling function in Internet routers for a variety of Internet applications. In order to classify Internet packets into flows, Internet routers must perform searches over a set of filters using multiple fields of the packet as the search key. Because of its speed and simple filter management the Ternary Content Addressable Memory (TCAM) is currently the dominant hardware solution for IP lookups, i.e., a one-dimensional packet classification. To make TCAM the solution for the multi-dimensional packet classification, efficient methods that store the range fields of the classification tables in TCAM are needed. In this paper, we propose a set of novel range encoding schemes based on Gray code. Many range-encoding techniques are used to improve the existing elementary interval- based range encoding schemes. The present experiment's results show that the proposed Gray code-based schemes consume less TCAM storage space than the existing schemes.
Impact of demographic distribution and population growth rate on haplotypic diversity linked to a disease gene and their consequences for the estimation of recombination rate: Example of a French Canadian population (1999)

A disease gene introduced into a rapidly growing population by a single individual remains in strong linkage disequilibrium with the surrounding molecular markers. Mapping strategies taking advantage of this phenomenon allow increased mapping resolution as compared to pedigree analysis. Demographic models underlying these strategies usually assume the population exponential growth approximated by Poisson distribution of the number of children per individual. Knowing the real demographic distribution in the studied French-Canadian population, we analyzed the validity of the Poisson approximation. We adapted the existing model of the Poisson branching process to the case of a rapidly growing population and to non-Poisson distributions. In consequence, we were able to apply maximum-likelihood methods to estimate the recombination rate under various demographic scenarios. Our analysis shows that the growth rate has a higher impact on the estimation of recombination rate than the shape of the demographic distribution. The choice of the demographic model (Poisson vs. non-Poisson) has little effect on the estimation of the recombination rate but affects the expected distribution of haplotype frequencies. This distribution, however, depends much more on the population growth rate. Finally, we also demonstrate the usefulness of the Luria-Delbrück method, which gives a correct estimation of the recombination rate in a growing population, provided the sampling error is taken into account in the confidence intervals.
The use of Probability-Multipliers in Replacement Analysis (1959)

Engineering economy analyses are often made for both the most and least favorable combinations of forecasted future conditions. This procedure has two major weaknesses. First, the two solutions usually indicate that contradictory courses of action should be followed. When this occurs, the engineeringeconomic study has failed to provide the management of a business with a quantitative aid and mathematical method for evaluating data and arriving at sound decisions. Second, that method of analysis is unrealistic because it emphasizes the extreme possibilities rather than some intermediate situation which is more likely to occur.
A Chemical Reaction Engineering Approach to Modelling Drying of Particulate or Thin Layer Materials (1997)

Drying is becoming a subject of extensive research in recent years due to its importance in manufacturing many types of products. Drying has been modelled by adopting the drying characteristic curve method, the comprehensive transport phenomena approach or the entirely empirical correlations. This paper describes a mechanistic model of drying using a chemical reaction engineering approach. This approach has been found to be useful in interpreting the insights of drying behaviour and appears to avoid some restrictions of the drying curve method. The fundamental aspects of the model are outlined and a case study is presented in this paper.
Inverse photoemission (1988)

Inverse photoemission spectroscopy (IPES) is the new name for bremsstrahlung isochromat spectroscopy. It is used to study the unoccupied electronic states in solids and at their surfaces. The author surveys accomplishments in ultraviolet IPES particularly in its angle-resolved form. The author starts with an outline of the phenomenology, history and the theories of inverse photoemission. Signal levels in ultraviolet IPES are about five orders of magnitude weaker than in forward photoemission. Large-aperture photon detector/selectors and high-perveance electron guns have been developed to overcome this difficulty. The author continues with some case studies. A section on bulk bandstructure includes a pedagogical section on band mapping of unoccupied states in metals and offers examples of spin polarised studies of ferromagnets and bandstructure determinations of semiconductors and layer materials. A section on clean surfaces surveys the various kinds of unoccupied surface states which have been observed-Shockley states, image states and d-like surface states. The systematics of Shockley-state and image-state formation can be described with the use of a heuristic multiple-reflection model. The way in which these systematics could lead to a determination of the surface potential barrier is discussed.
The Chrysler A-604 Ultradrive 4-Speed Automatic Transaxle (1989)

<div class="htmlview paragraph">A new kind of four-speed automatic transaxle, engineered from concept specifically for real-time closed-loop electronic control, has been designed, developed, and put into production by Chrysler Motors Corporation. This overdrive transaxle combines two simple planetary gear sets with five disc-clutches, five hydraulic spool valves, and four direct-acting three-way solenoid valves to achieve all operating modes. It uses no bands and only the torque converter stator has a freewheel element. It provides both a fourth ratio and increased engine torque capacity in the same package space used by the previous three-speed transaxle. At the same time, fewer parts are required and manufacturing is more readily automated.</div>
The <i>porA</i> pseudogene of <i>Neisseria gonorrhoeae</i>– low level of genetic polymorphism and a few, mainly identical, inactivating mutations (2005)

N. meningitidis is the only Neisseria species known to express two outer membrane porins, PorA and PorB. However, a porA pseudogene has been identified in N. gonorrhoeae. The present study investigated the prevalence and genetic polymorphism of this porA pseudogene in 87 different N. gonorrhoeae strains. The porA pseudogene was identified in all isolates. The pseudogene comprised 12 (5.5%), of which 10 were located in the promoter spacer, and 11 (1.0%) polymorphic nucleotide sites in the upstream segment containing the promoter region, i.e. the putative -10 and -35 sequences and the promoter spacer in-between, and the hypothetical PorA coding sequence, respectively. A phylogenetic analysis of the upstream segment and the hypothetical coding sequence identified 36 sequence variants, of which 30 were not previously described. All strains comprised at least two identical confirmed inactivating deletions, of which one was located in the promoter region and one in the hypothetical PorA coding sequence. In conclusion, the porA pseudogene and its few inactivating mutations are widespread in the N. gonorrhoeae population and the homology with the N. meningitidis porA gene reflects their common evolutionary origin. The highly conserved N. gonorrhoeae porA pseudogene may reflect an evolutionary neutral molecular clock and may be a suitable genetic target for diagnosis of N. gonorrhoeae.
Reduced-tree-based soft decoding for block-coded modulation (1997)

It is shown that soft maximum-likelihood decoding for block-coded modulation (BCM) can be performed using the code tree. It is easy to generate the code tree for any type of block code, linear as well as nonlinear. A reduced tree is obtained from the code tree. The trellis for a block code can be obtained from the reduced tree. Using this structure to perform computations in parallel, a scheme is proposed for the implementation of the soft decoder. Back tracking, necessary in a soft decoder using the Viterbi algorithm on a trellis, is eliminated.
Research of Distributed Parallel Computing Based on Mobile Agent (2007)

This paper introduces the mobile agent technology, and presents a new approach to realizing the distributed parallel computing based on mobile agent. With the Miller-Rabin primality test as an example, the working process and the realization method are introduced in detail. The numerical experiment shows that the speedup and the parallel efficiency of this program are high enough, and the stability of the distributed parallel computing is improved, as well as the flexibility, the expansibility and the mobility.
Review of naphthenic acid corrosion in oilrefining (1999)

Naphthenic acid corrosion is a major concern for the oil refinery business. While much is now known about the phenomenon, it is still not completely understood because of the complex influences on corrosion of the type of acid and other constituents in the crude oil and the effects of both temperature and fluid flow. A review of this form of corrosion has been undertaken with respect to the role of crude oil composition, temperature, fluid velocity, physical state (vapour or liquid), pressure, and materials of construction. Simple measures of corrosivity based on the total acid or neutralisation number are insufficient. The sulphur content of the crude is important but the extent to which the various sulphur containing compounds act as inhibitors or corrodents is not understood. There is little knowledge also of the nature of films formed on the steel surfaces under operating conditions and the role of natural inhibitors that may be present in crudes requires more attention.

A new switched-capacitor frequency modulated driver for light emitting diodes (2007)

A new type of drivers for light emitting diodes (LEDs) is introduced based on the switched-capacitor frequency modulation. In contrast to conventional constant dc current drivers, the current pulse is provided by this new switched-capacitor LED driver. In the present driver, the charging capacitor is charged and discharged through a LED and the current flow direction is controlled by a metal oxide semiconductor switch. The input current (and thus the LED brightness) is proportional to the switch clock frequency at relatively low frequencies and becomes saturated at relatively high frequencies. This new driver circuit is simple and robust and maintains high efficiency for a wide range of input powers. In addition, the dimming control is easily realized by modulating clock frequency. Finally, this LED driver consumes no dc current and thus provides inherent protection to LED in standby mode.
Variation in Anther and Stigma Characteristics in Rice (1979)

In search of ideal attributes of male and female floral characteristics, that would improve cross-pollination, in all 5669 cultivated varieties, 1145 F1 hybrids and 94 forms of 9 wild allies of O. sativa were extensively screened. The study revealed a wide variation for length and breadth of anther and stigma, extent of elongation of filaments and style and the degree of protrusion of anthers and stigma. There were types with ideal floral features both among cultivated and wild species. For instance, types such as IARI 5824, IARI 5823, IARI 10536, IARI 10537, IARI 10668, IARI 11567, IARI 5821, IARI 5819, IARI 6193-G, IARI 11427, IARI 7253-A, and IARI 11226 have been found to have relatively long and broad anthers with distinct filament elongation while types like IARI 6637, IARI 7332, IARI 10979-A, IARI 10255-A, IARI 10255, IARI 10662, IARI 11143, IARI 11205, IARI 10212, IARI 10449, IARI 10574, IARI 10758 and IARI 10871 were having larger stigma and longer style with well-protruded stigma for longer periods. A numerical index, the ratio of anther size to stigma surface, has been found to be negateively related to the percentage of stigmatic exsertion. Based on the extent of usable variability available in the cultivated and closely related species for various floral characterstics, the possibilities of restructuring rice flower so as to facilitate increased cross pollination have been discussed.
Scatter modeling for 3-d PET list-mode EM reconstruction (2004)

It is widely recognized that scattered radiation is a significant issue in 3-D positron emission tomography (PET). This work proposes a method to address the modeling and correction of scatter in PET studies when using the 3-D list-mode expectation-maximization (EM) algorithm. The rationale of this technique is to directly incorporate an estimated scatter function into the system model of the 3-D list-mode EM algorithm. In this initial work, the scatter model assumes that the scatter distribution can be described by, a convolution of the true activity estimate with a scatter kernel. For small-volume studies acquired with the quad-HIDAC, it is expected that convolution with a shift-invariant scatter kernel will be adequate to describe the broad scatter distributions encountered. It is anticipated that the method proposed here will offer an improvement upon techniques that use subtraction of the scatter background estimate.
Absorption, metabolism, and tolerance of polyol sugar substitutes. (1978)

Flora Whitney, Quentin Roosevelt's fiance, visited for dinner, and Theodore Roosevelt found her to be the "dearest girl." Quentin is very fortunate. Roosevelt has been disappointed that he could not join the war effort but these feelings have been swept away by "immense pride" in his sons. He hopes to continue working until his sons come home so that he can start Archibald Roosevelt and Quentin out all right. Then he will retire because an "elderly male Cassandra" can do little work and is more of a nuisance. Roosevelt's new book, The Foes Of Our Own Household , will soon be published and dedicated to his children and their spouses. Flora will receive her own copy with a special inscription.

Proteomic Study of Peptide Deformylase Inhibition in<i>Streptococcus pneumoniae</i>and<i>Staphylococcus aureus</i> (2006)

Peptide deformylase (PDF) is an essential enzyme in both gram-negative and gram-positive bacteria. It hydrolyzes formylated N-terminal peptides to generate free N-terminal peptides during the process of protein maturation. Inhibition of this enzyme results in cessation of bacterial growth. We have examined the effect of a potent PDF inhibitor, LBM-415 (also known as VIC-104959), on the proteomes of Staphylococcus aureus and Streptococcus pneumoniae using two-dimensional electrophoresis. Both S. aureus and S. pneumoniae showed accumulation of many N-terminal formylated peptides/proteins upon PDF inhibition. In S. pneumoniae, formylated peptide/protein accumulation was time dependent. Following inhibition, subsequent removal of the inhibitor resulted in deformylation of formylated peptides/proteins; this recovery process was also time dependent. If instead the inhibited cells were maintained in the presence of sub-MIC levels of the PDF inhibitor, the formylated peptides/proteins remained for a much longer time, which correlated with a prolonged postantibiotic effect in vitro. These observations may have broader implications for the application of this class of antibiotics in vivo.
Sticky superhydrophobic surface (2007)

The authors present a simple and inexpensive method for fabricating a stable superhydrophobic engineering material surface using aluminum alloy and a suitable aqueous solution and time to control the surface roughness, which has a large water contact angle (&gt;150°) and a large water sliding angle (&gt;90°). The as-prepared surface can be large-scale produced and used in industry quickly, such as a barrier material, self-cleaning material, and lubricating material. This finding will enhance further understanding of the wettability of solid surfaces with special surface morphologies.
The Solubility of Amino Acids, Diglycine, and Triglycine in Aqueous Guanidine Hydrochloride Solutions (1970)

Abstract The solubilities of amino acids, diglycine, and triglycine have been measured in water and 1 m to 6 m guanidine hydrochloride solutions. Free energies of transfer of amino acid side chains and backbone peptide units from water to guanidine hydrochloride solutions have been calculated from these data. The results show similarity between the patterns of solubilizing effects of guanidine hydrochloride and urea, although guanidine hydrochloride is 2 to 3 times more effective than urea at the same concentrations.
The GRAIL Project: An Experiment in Man-Machine Communications (1969)

This Memorandum is the first of a three-part final report on the GRAIL (GRAphical Input Language) Project sponsored by the Advanced Research Projects Agency of the Department of Defense. The study was an integral part of both RAND's and the client's overall program to explore man-machine communications. The Memorandum states the philosophy adhered to in this computer-graphics experiment, describes the problems that were identified, and notes further research directed to these problems. The techniques developed are described in the context of the experiment itself although they are suitable for a larger class of applications.
The stroboscopic Pulfrich effect is not evidence for the joint encoding of motion and depth (2005)

In the Pulfrich effect, an illusion of depth is produced by introducing differences in the times at which a moving object is presented to the two eyes. In the classic form of the illusion, there is a simple explanation for the depth percept: the interocular delay introduces a spatial disparity into the stimulus. However, when the moving object is viewed stroboscopically, this simple explanation no longer holds. In recent years, depth perception in the stroboscopic Pulfrich effect has been explained by invoking neurons that are sensitive both to stereo disparity and to direction of motion. With such joint motion/disparity encoders, interocular delay causes a perception of depth by causing a shift in each neuron's preferred disparity. This model has been implemented by N. Qian and R. A. Andersen (1997). Here we show that this model's predictions for perceived disparity are quantitatively at odds with psychophysical measures. The joint-encoding model predicts that the perceived disparity is the virtual disparity implied by the apparent motion; in fact, the perceived disparity is smaller. We show that the percept can be quantitatively explained on the basis of spatial disparities present in the stimulus, which could be extracted from pure disparity sensors. These results suggest that joint encoding of motion and depth is not the dominant neuronal basis of depth perception in this stimulus.
