Mammalian Cell Physiology (2018)

Mammalian cells are gaining popularity as expression systems for complex proteins of human pharmaceutical interest in the biotechnology industry. This chapter focuses on the aspects of cell physiology that include the transport and metabolism of key nutrients, specifically amino acids and carbohydrates. Carbohydrates perform a variety of functions in mammalian cells, from precursors of other small molecules and macro molecules to oxidizable energy substrates. Amino acids play a central role in the metabolism of animal cells in culture. They perform many diverse functions, from building materials for protein synthesis to acting as oxidizable energy substrates. Many amino acids serve as precursors for important small molecules within cells. Examples of these include polyamine synthesis from arginine, glutathione synthesis from glycine, choline synthesis from serine, and purine synthesis from glycine, glutamine, and aspartate. The chapter provides a discussion on the role of oxygen in cell culture.
Interference cancelation scheme with variable bandwidth allocation for universal filtered multicarrier systems in 5G networks (2018)

The universal filtered multicarrier (UFMC) is an appealing technique to eliminate out-of-band emission (OOBE) for fifth-generation (5G) networks. However, its signals that are modulated to the carriers, which are on the edges of one subband, are influenced by the filter. In this paper, an interference cancelation scheme is proposed to suppress the interference and to improve the multiuser system performance. Here, interference cancelation subcarriers are inserted on the edges to reduce the filter interference. This scheme ensures that the operating subregion or subband supports the variable bandwidth allocation to meet the requirements of 5G networks. Simulation results show that the bit error rate (BER) performance improves by 4 and 7 dB compared with that of the conventional UFMC when the corresponding Eb/N0 is 15 and 20 dB. Comparisons with both the standard OFDM and the GB OFDM are also reported. The results demonstrate that the proposed UFMC scheme outperforms the other two systems, especially compared with the GB OFDM system under the condition of the same spectral efficiency.
Thoughts on k-Anonymization (2006)

k-Anonymity is a method for providing privacy protection by ensuring that data cannot be traced to an individual. In a k-anonymous dataset, any identifying information occurs in at least k tuples. To achieve optimal and practical k-anonymity, recently, many different kinds of algorithms with various assumptions and restrictions have been proposed with different metrics to measure quality. This paper presents the family of clustering based algorithms that are more flexible and even attempts to improve precision by ignoring the restrictions of user defined Domain Generalization Hierarchies. The main finding of the paper will be that metrics may behave differently through different algorithms and may not show correlations with some applications’ accuracy on output data.
A Noise Addition Scheme in Decision Tree for Privacy Preserving Data Mining (2010)

Data mining deals with automatic extraction of previously unknown patterns from large amounts of data. Organizations all over the world handle large amounts of data and are dependent on mining gigantic data sets for expansion of their enterprises. These data sets typically contain sensitive individual information, which consequently get exposed to the other parties. Though we cannot deny the benefits of knowledge discovery that comes through data mining, we should also ensure that data privacy is maintained in the event of data mining. Privacy preserving data mining is a specialized activity in which the data privacy is ensured during data mining. Data privacy is as important as the extracted knowledge and efforts that guarantee data privacy during data mining are encouraged. In this paper we propose a strategy that protects the data privacy during decision tree analysis of data mining process. We propose to add specific noise to the numeric attributes after exploring the decision tree of the original data. The obfuscated data then is presented to the second party for decision tree analysis. The decision tree obtained on the original data and the obfuscated data are similar but by using our method the data proper is not revealed to the second party during the mining process and hence the privacy will be preserved.
Mechanism of Aneurysm Formation after 830-nm Diode-Laser-Assisted Microarterial Anastomosis (1997)

The results show that there are two important factors that cause aneurysm formation after laser-assisted anastomosis: 1) the vessel wall is damaged by laser heating; 2) proliferation of collagen fiber at the adventitia is absent during media reconstruction.
The MWA Archive: A Multi-tiered Dataflow and Storage System (2013)

Generalized augmented transition network grammars for generation from semantic networks (1982)

The augmented transition network (ATN) is a formalism for writing parsing grammars that has been much used in Artificial Intelligence and Computational Linguistics. A few researchers have also used ATNs for writing grammars for generating sentences. Previously, however, either generation ATNs did not have the same semantics as parsing ATNs, or they required an auxiliary mechanism to determine the syntactic structure of the sentence to be generated. This paper reports a generalization of the ATN formalism that allows ATN grammars to be written to parse labelled directed graphs. Specifically, an ATN grammar can be written to parse a semantic network and generate a surface string as its analysis. An example is given of a combined parsing-generating grammar that parses surface sentences, builds and queries a semantic network knowledge representation, and generates surface sentences in response.
Design of an Infrared based Blood Oxygen Saturation and Heart Rate Monitoring Device (2009)

The purpose of the project was to design a remote non-invasive health monitoring system. Health information would be collected and transferred to a processing centre wirelessly, where it can be monitored and forwarded to necessary personnel. Heart Rate and Blood Oxygen Saturation are a couple of such biometrics that are monitored in this project. Change in intensity of light transmitted through tissue due to arterial blood pulse can be measured as a voltage signal. This technique is called Photoplethysmography (PPG), and can be used to calculate the heart rate. Furthermore, oxygenated blood has different light absorption characteristics than deoxygenated blood under Red and Infrared wavelengths. Comparing the two absorptions can produce an estimate of the oxygen saturation of the blood. Time Multiplexing was sued to collect the two PPGs (Red and Infrared) simultaneously. The hardware design and the software processing required to measure these biometrics will be presented.
Influence of Elevated Polyunsaturated Fatty Acids on Processing and Physical Properties of Butter (1975)

Milk fat containing varied percents of linoleic acid (from 1.8 to 28.0% of the fatty acids) from feeding cows a protected lipid supplement and by blending conventional and polyunsaturated milk fats was used to make experimental butters by churning and by the continuous Votator system. Measurements were made of the hardness of the butters by disk and cone penetrometers, of melting characteristics of the milk fats by dilatometry, of butters by nuclear magnetic resonance, and of oiling off properties at 10 and 20 C. The higher the linoleic content of the milk fat, the softer the butter. Comparison at similar linoleic percents of butters made from milk fat as produced and those from blends of conventional and polyunsaturated milk fat showed that products from blends were harder, had a wider temperature range at which they were plastic, and were less susceptible to oiling off at 20 C. Below 12 C butter made by the continuous Votator system was appreciably harder than that by churning, but at higher temperatures hardness of the two butters was similar. The results indicate possibilities for improving the spreadability of butter by manipulating the composition and physical properties of milk fat by feeding cows protected lipid supplement.
Adaptive cross-sensor beam forming with planar arrays (1977)

In cross-sensor beamforming the narrow-band quadrature signal at one sensor is multiplied by the complex conjugate of the narrow-band quadrature signal at a second sensor to form a stable element of the cross-sensor field. After suitable time averaging, the beam response can be calculated as the weighted correlation between the cross-sensor field that is measured and the field that is expected. If N sensors form a sparse line array, then N lines form a sparse square array. Examples are given showing the performance of a sparse square array and a random planar array in resolving a realistic multiwave signal plus noise field. A simple adaptive algorithm is used to resolve weak signals close to strong signals and to reduce sidelobe problems associated with a random array.
Acoustic source localization in mixed field using spherical microphone arrays (2014)

Spherical microphone arrays have been used for source localization in three-dimensional space recently. In this paper, a two-stage algorithm is developed to localize mixed far-field and near-field acoustic sources in free-field environment. In the first stage, an array signal model is constructed in the spherical harmonics domain. The recurrent relation of spherical harmonics is independent of far-field and near-field mode strengths. Therefore, it is used to develop spherical estimating signal parameter via rotational invariance technique (ESPRIT)-like approach to estimate directions of arrival (DOAs) for both far-field and near-field sources. In the second stage, based on the estimated DOAs, simple one-dimensional MUSIC spectrum is exploited to distinguish far-field and near-field sources and estimate the ranges of near-field sources. The proposed algorithm can avoid multidimensional search and parameter pairing. Simulation results demonstrate the good performance for localizing far-field sources, or near-field ones, or mixed field sources.
Synthesis of Micheliolide Derivatives and Their Activities against AML Progenitor Cells (2013)

Micheliolide (MCL) derivatives with etherification or esterification of the hydroxyl group at the C4 position were synthesized and evaluated for their activities against different acute myelogenous leukemia (AML) cell lines. These derivatives demonstrated comparable activities against AML cell lines HL-60 and doxorubicin resistant cell line HL-60/A. As to multi-drug resistant AML progenitor cells KG-1a, MCL and some of its derivatives maintained significant activities, and only 1.1-2.7 fold activity reductions were observed when compared with the activities against HL-60, while doxorubicin showed 20-fold activity reduction. Our study demonstrated that the C4 hydroxyl group of MCL might not only be a suitable position for structural modifications, but also be a starting point for the design of appropriate molecular probes to explore the specific targets in the progenitor cell line KG-1a.

Universal percolation-threshold limits in the continuum (1985)

The existing criteria for the onset of percolation in the continuum are limited to systems of parallel-aligned, equal-size, penetrable, convex objects. We present here criteria for the much more general case of macroscopically isotropic or anisotropic systems in which the objects may also be of variable sizes and of random orientations. It is found that the critical fractional occupied area (or the equivalent average critical total excluded area 〈${A}_{\mathrm{ex}\mathrm{〉}}$) as well as the critical fractional occupied volume (or the equivalent 〈${V}_{\mathrm{ex}\mathrm{〉}}$) are confined within two limits. The upper limit is that of the ``parallel objects'' systems and the lower limit is that of the (newly introduced) ``horizontal-vertical'' system. These limits are 3.2\ensuremath{\le}〈${A}_{\mathrm{ex}\mathrm{〉}\mathrm{\ensuremath{\le}}4.5}$ and 0.7\ensuremath{\le}〈${V}_{\mathrm{ex}\mathrm{〉}\mathrm{\ensuremath{\le}}2.8}$. .AE
A High Reliable and Performance Data Distribution Strategy: A RAID-5 Case Study (2013)

With the development of the storage medium, such as the emerging of the SSD, the tradition way of data distribution can't keep up with the pace of the storage device development. Specifically, for example, Traditional RAID only enhanced the performance or reliability in the single storage medium and all the data are distributed in the same storage medium. But with the wide range of using raid, the problem of RAID data adventure has come to the surface gradually. Furthermore, under the mode of RAID-5 read modify-write (R-M-W), operation system collapse or the storage medium write error would lead to the damage of data, which could not be recovered and this problem is named write hole. According to the above problem, this paper proposes a new data distribution strategy, which is called high reliable and performance data distribution strategy (RPDD). RPDD use the high performance storage medium as a cache which is named storage cache. The most of the data is wrote to the storage cache and then distribute the data to the other logic relationship storage medium. As a result, the data is distributed in a hybrid storage medium. In order to take a better analysis of the RPDD in the next, we have combined RPDD in the RAID-5, which is named RAID-5-RPDD. RAID5-RPDD employs the dynamic scheduling mechanism, data transfer and hybrid consistency mechanism between the SSD and magnetic media storage devices to resolve the problem. In consequence, it can protect the RAID stripe data consistency under the condition of R-M-W and increase the I/O performance without the impact of the cost. In addition, it can improve the reliability of the RAID-5. The simulation test results show that RAID-5-RPDD I/O performance increase at the range of 9% with little penalty of the resource consumption.
The Correlation between the Effectiveness of Brief Qigong-based Stress Reduction Program(BQSRP) and Personality (2010)

Objectives : The aim of this study was to investigate the correlation between the effectiveness of Brief Qigong-based Stress Reduction Program(BQSRP) and personality. Methods : Twenty nine women and nine men from the community with symptoms of distress(mean age 39.4 years, SD=11.4) were randomized into a group receiving a 4-week intervention of BQSRP(n=19) or a waiting-list control group. All subjects completed the temperament and character inventory (TCI) before the intervention. Before and after the intervention period, questionnaires were completed on perceived stress scale(PSS), anxiety, and quality of life. Results : 1. Those who have higher temperament of harm avoidance or lower character of self-directedness showed higher PSS, Hwa-Byung character, Hwa-Byung symptom, STAI and lower WHOQOL-BREF scores. 2. In the BQSRP training group, a correlation analysis demonstrated an association between higher temperament of harm avoidance and greater improvement of perceived stress and an association between lower character of self-directedness and greater improvement of perceived stress. 3. Those who have high Hwa-Byung symptom scores prefer the breathing meditation and there were no differences in effects of BQSRP group by the preference Brief Qigong-based Meditation(BQM) component. Conclusions : These results suggest that a BQSRP training may be effective for those with higher harm avoidance trait and low self-directedness.
The sensor of traveling-wave for fault location in power systems (2005)

The fault-generated high frequency signals contain much information which can be used to accurately locate the fault point in power systems. For capturing the high frequency signals, two specially designed traveling-wave sensors are developed in the paper. One is the current sensor installed on the earth line of capacitive equipment (such as: CVT, capacitive CT, transformer bushing, wall bushing) to capture the current traveling-waves flowing from the equipment to earth. The other is the voltage sensor installed at the zero sequence winding of a voltage transformer to capture the voltage traveling waves in three-phase generated by faults. The fault location system with the traveling wave sensors is also developed simply. The sensors and the fault location system have been tested on an 110 kV power system. Results show that the sensors have good performance to capture traveling-waves and the error of fault location is no more than 120 m.

Selection criteria for computer software and hardware: A case study of six university libraries in Nigeria (2011)

This paper investigates the criteria used in the selection of computer hardware and software in six university libraries in Nigeria. Six (6) copies of a questionnaire were sent to selected librarians in Edo and Delta states, Nigeria. All copies of the questionnaire were retrieved. The data collected were analyzed. The findings reveal that the respondents took into consideration such factors as memory, speed, capacity, durability, costs, reliability and standardization, brand and manufacturer, warranty, and scalability of the system before procuring computer hardware. The respondents also take into consideration the reliability and track record of the vendor, service and technical support, previews or sample sections, compatibility with other programs being used, product cost, and data migration before procuring computer software. It is also noteworthy that the respondents have encountered with electricity failure, improper implementation, and difficulties to get qualified personnel to maintain and/or repair computer hardware when it was broken down.
Cognitive Theory of Multimedia Learning (2005)

A fundamental hypothesis underlying research on multimedia learning is that multimedia instructional messages that are designed in light of how the human mind works are more likely to lead to meaningful learning than those that are not. The cognitive theory of multimedia learning (CTML) is based on three cognitive science principles of learning: the human information processing system includes dual channels for visual/pictorial and auditory/verbal processing (i.e., dual-channels assumption); each channel has limited capacity for processing (i.e., limited capacity assumption); and active learning entails carrying out a coordinated set of cognitive processes during learning (i.e., active processing assumption). The cognitive theory of multimedia learning specifies five cognitive processes in multimedia learning: selecting relevant words from the presented text or narration, selecting relevant images from the presented illustrations, organizing the selected words into a coherent verbal representation, organizing selected images into a coherent pictorial representation, and integrating the pictorial and verbal representations and prior knowledge. Multimedia instructional messages should be designed to prime these processes.
Performance-functional based controller design for a mobile manipulator (2003)

Mobile manipulators with more than 6 degrees of freedom (DOF) provide a large working space with high end effector dynamics. The paper shows how mobile manipulators consisting of a normal robot arm on a wheeled mobile base can be controlled. The coordination of movements of the robot and the base is determined by using a direct task-space control. The task vector is augmented by the redundant DOF's of the base, so that the external and internal motions of the manipulator can be determined by means of optimal control theory. The reference values of the augmented coordinates are derived from the end effector references. This is done by optimizing robot arm kinematics under the dynamic conditions of the base. Furthermore, it is shown how not task-determined end effector DOF's can be used to improve the dynamic characteristics of the remaining DOF's. As an example, the proposed controller design is used to coordinate the movements of a mobile manipulator with nine DOF's and nonholonomic constraints.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Measuring the Thermal Resistance in Light Emitting Diodes Using a Transient Thermal Analysis Technique (2013)

We explore a modified thermal resistance analysis by induced transient method applied to light emitting diodes (LEDs) to discretize the junction-to-package thermal resistance. The temperature response of LED and package configuration is evaluated for discrete contributions from identifiable spatial domains in the multilayered device and package structure to obtain their thermal resistances and thermal capacitances using a Laplace transform-based method. The technique successfully extracts the junction-to-package thermal parameters of a variety of LED package configurations from the experimental temperature transient measurements of the LED junction and provides a straightforward method by which these parameters can be obtained.
Time-Resolved Investigations of Stimulated Brillouin Scattering in Transparent and Absorbing Media: Determination of Phonon Lifetimes (1970)

Stimulated Brillouin scattering was studied both theoretically and experimentally. The evolution in time of the scattering process, its dependence on frequency, and the influence of optical absorption were analyzed. For quantitative investigations, the individual shapes of the laser and signal pulses were taken into account. Strong transient effects predicted by theory were confirmed experimentally. The amplification of Brillouin light was measured in a generator-amplifier system using single-mode giant laser pulses. Several liquids, glasses, and quartz were investigated. The experimental results allow the determination of phonon lifetimes $\ensuremath{\tau}$ and of elasto-optic constants. In our amplifier system, accurate values of $\ensuremath{\tau}$ are obtained for $\ensuremath{\tau}<3$ nsec, i.e., for liquids and some solids. The limitation of the method is discussed. In absorbing media, stimulated thermal Brillouin scattering was observed in quantitative agreement with theory.
