Expression of latent hematopoietic progenitor cells in cultures of newborn and adult baboon liver (1985)

The anatomic site of hematopoiesis changes during fetal development from the yolk sac to the liver and finally to the marrow. Factors controlling this switch in the site of hematopoiesis are unknown. We assayed erythroid colony (CFU-E) and erythroid burst (BFU-E) formation in fetal, newborn, and adult baboon liver and marrow to determine the growth requirements of primate hematopoietic progenitor cells from different anatomic sites and developmental stages. We cocultured fetal, newborn, and adult liver and marrow nonadherent cells with adherent cells from these organs to assess the role adherent cells may play in determining the site of hematopoiesis. Fetal liver, fetal marrow, newborn marrow, and adult marrow cultures formed CFU-E and BFU-E colonies in vitro. In contrast, newborn and adult liver cell cultures very rarely formed colonies. However, when newborn or adult liver nonadherent cells were cocultured with marrow adherent cells, CFU-E and BFU-E colonies were detected. The colonies that formed in the newborn and adult liver cultures were derived from the liver and not from the marrow cells or peripheral blood trapped in the liver. These data suggest that in contrast to fetal liver, newborn and adult liver may not be hematopoietic organs in normal primates in vivo because of changes in the growth requirements of hematopoietic progenitor cells present in these organs.

Facile Preparation of the Porous PDMS Oil‐Absorbent for Oil/Water Separation (2016)

Nowadays, oily wastewater and spilled oil have caused great threats on both ecosystem and human life. To address these severe problems, considerable efforts have been possessed on developing novel oil/water separation materials. The porous oil‐absorbent materials, especially the porous polydimethylsiloxane (PDMS) with excellent properties of easy fabrication and inherent hydrophobicity, have attracted tremendous attentions from worldwide. The conventional methods using salt or sugar as sacrificial template and water as solvent have been widely adopted to fabricate the porous PDMS sponge. Due to the inherent hydrophobicity of PDMS, the solvent of water hardly penetrates into the inside of PDMS, which results in the difficult and incomplete remove of the hard template. In this contribution, the 3D interconnected porous PDMS sponge is facilely prepared by utilizing a modified technique with the citric acid monohydrate as hard template and ethanol as solvent. The proposed approach is capable of removing the hard template efficiently and thoroughly, which demonstrates promising utilizations in practical applications.
Metabolic engineering of Yarrowia lipolytica to produce chemicals and fuels from xylose (2016)

Yarrowia lipolytica is a biotechnological chassis for the production of a range of products, such as microbial oils and organic acids. However, it is unable to consume xylose, the major pentose in lignocellulosic hydrolysates, which are considered a preferred carbon source for bioprocesses due to their low cost, wide abundance and high sugar content. Here, we engineered Y. lipolytica to metabolize xylose to produce lipids or citric acid. The overexpression of xylose reductase and xylitol dehydrogenase from Scheffersomyces stipitis were necessary but not sufficient to permit growth. The additional overexpression of the endogenous xylulokinase enabled identical growth as the wild type strain in glucose. This mutant was able to produce up to 80g/L of citric acid from xylose. Transferring these modifications to a lipid-overproducing strain boosted the production of lipids from xylose. This is the first step towards a consolidated bioprocess to produce chemicals and fuels from lignocellulosic materials.
Optical Fiber Sensors for Aircraft Structural Health Monitoring (2015)

Aircraft structures require periodic and scheduled inspection and maintenance operations due to their special operating conditions and the principles of design employed to develop them. Therefore, structural health monitoring has a great potential to reduce the costs related to these operations. Optical fiber sensors applied to the monitoring of aircraft structures provide some advantages over traditional sensors. Several practical applications for structures and engines we have been working on are reported in this article. Fiber Bragg gratings have been analyzed in detail, because they have proved to constitute the most promising technology in this field, and two different alternatives for strain measurements are also described. With regard to engine condition evaluation, we present some results obtained with a reflected intensity-modulated optical fiber sensor for tip clearance and tip timing measurements in a turbine assembled in a wind tunnel.
A Materials Approach to Site‐Isolation of Grubbs Catalysts from Incompatible Solvents and <i>m</i>‐Chloroperoxybenzoic Acid (2008)

The development of a method for site-isolation of Grubbs second-generation catalyst from MCPBA is described. In these reactions, Grubbs catalyst was dissolved in a solvent consisting of a mixture (1:1 v/v) of 1-butyl-3-methylimidazolium hexafluorophosphate and methylene chloride and completely encapsulated within a thimble fabricated from polydimethylsiloxane (PDMS). A series of molecules that react by cross metathesis or ring-closing metathesis were added to the interior of the thimble and allowed to react. In the last step, m-chloroperoxybenzoic acid (MCPBA) dissolved in MeOH/H(2)O (1:1 v/v) was added to the exterior of the PDMS thimble. Small organic molecules diffused through the PDMS to react with MCPBA to form epoxides, but the Grubbs catalyst remained encapsulated. This result is important because Grubbs catalyst catalytically decomposes MCPBA at ratios of MCPBA to Grubbs of 3000 to 1. The yields for this two-step cascade sequence ranged from 67 to 83 %. The concept behind this sequence is that small organic molecules have high flux through PDMS but large molecules--such as Grubbs catalyst--and ionic reagents--such as MCPBA--have much lower flux through PDMS. Small molecules can thus react both outside and inside PDMS thimbles, whereas incompatible catalysts and reagents remain site-isolated from each other. This method does not require alteration of structures of the catalysts or reagents, so it may be applied to a wide range of homogeneous catalysts and reagents. To demonstrate further that the catalyst was encapsulated, the Grubbs catalyst was successfully recycled within the cascade sequence.

Study on Battery Management System and Lithium-ion Battery (2009)

This paper mainly discusses a distributed battery management system (BMS) that used for hybrid electrical vehicle (HEV) and the research on Lithium-ion battery based on the model of PNGV. The BMS presented is composed with the distributed and integrated module, the distributed modules(DM) takes charge of measuring the parameters of voltage and temperature accurately and in time, communicate with the integrated module(IM) by CAN bus. The IM takes charge of estimating Lithium-ion batteriespsila state of charge (SOC) based on the data of DM and PNGV model. According to the complicated electromagnetism condition the anti-jamming methods are used between every part of the BMS to have the characters of robustness and reliability. According to the non-liner feature of Lithium-ion battery, PNGV model has the high accuracy to reflect the open circuit voltage (OCV) and SOC. Results show that the BMS has the characteristics of easy to expansion, high precision, working reliability and the PNGV model is suitable for Lithium-ion battery.
Die-Offs of Pre-Spawn Adult Pink Salmon and Chum Salmon in Southeastern Alaska (1985)

About 300 pre-spawn adult pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta) died in August 1981 in the intertidal reach of Porcupine Creek, a small stream in an old-growth forest. A combination of low stream flow and neap tides triggered the die-off, and about 1% of the pink salmon and chum salmon spawners died upon returning to Porcupine Creek in 1981. Anoxia, rather than temperature, caused most of the deaths because the maximum stream temperature was 19 C—well below lethal temperatures. Conditions similar to those in 1981 recur in Porcupine Creek about once every 8 years. This type of die-off also appears to be common in other streams in southeastern Alaska and can be predicted from the number of salmon returning, amount of precipitation, and height of the tide.

ASurvey ofProcess Migration Mechanisms (2001)

We define process migration as the transfer of a sufficient amount of a process’s state from one machine to another for the process to execute on the target machine. This paper surveys proposed and implemented mechanisms for process migration. We pay particular attention to the designer’s goals, such as performance, load-balancing, and reliability. The effect of operating system design upon the ease of implementation is discussed in some detail; we conclude that message-passing systems simplify designs for migration. 1.
Transform coding at 4.8 kbit/sec using interleaving of transform frames and dual gain-shape vector quantisation (1993)

The dual gain shape VQ (vector quantization) transform coding algorithm refines the distribution of quantization resources by supplementing interband bit allocation with intraband reallocation, and, by introducing two levels of vector normalization, allows the design of more efficient codebooks. Better use of limited bit resources at the coding rate of 4.8 kbit/s is thus achieved, yielding a 1 dB improvement in coding performance. The introduction of frame overlapping in the transform domain, by implementing a continuous frame interleave, gives significant improvements in the subjective quality of the coded speech. The effect produced by interleaving could be explained as an exploitation of interframe correlation, in creating vectors for VQ, and as an implicit promotion of frame interdependency in bit allocations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Investigations on vehicle rollover prevention using open loop steer-by-wire system (2014)

This paper presents results of an initial investigation into models and control strategies suitable to predict and prevent vehicle rollover due to untripped driving maneuvers. Outside of industry, the study of vehicle rollover inclusive of experimental validation, model-based predictive algorithms, and practical controller design is limited. The researcher interested in initiating study on rollover dynamics and control is left with the challenging task of identifying suitable vehicle models from the literature, comparing these models in their ability to match experimental results, and determining suitable parameters for the models and controller gains. For vehicles that are deemed to be susceptible to wheel-lift, various open-loop control strategies are implemented in simulation. The primary assumption in their implementation is that the vehicle in question is equipped with a steer-by-wire system.
Design and Development of Efficient Cloud Scheduling Algorithm based on Load Balancing Analytics (2016)

Cloud computing involves sharing computing resources rather than having individual servers or personal devices to handle applications. Cloud computing architectures include the delivery of software, infrastructure, storage and technology enabled services over internet to the people and organizations on demand. Cloud scheduling is the process of allocating resources to the job requests in the form of Virtual Machines. In this paper we designed and developed a novel, efficient cloud scheduling algorithm based on load balancing analytics for allocation of physical resources in the form of virtual machine to the incoming job requests. In this paper we measured various cloud performance metrics like mean turnaround time and mean waiting time. The results obtained with this method compared with traditional methods like First Come First Serve (FCFS), two stage scheduling algorithms and observed considerable increase in the performance Metrics.

Noonan syndrome: Psychological and psychiatric aspects (2007)

Although Noonan syndrome (NS) is a disorder with a relatively high prevalence, virtually no information in adult patients is available about the psychological and psychopathological profile. In the present clinical report the first series of 10 NS patients from an ongoing project is presented. The purpose of the study is to investigate the psychopathology, social cognition and adaptation as well as the quality of life in NS patients aged 16 years or more. PTPN11 mutations were present in six patients and KRAS and SOS1 in one patient, respectively. In two patients no known mutation was found. The results demonstrate a variable level of intelligence and suggest moderately impaired social cognition in terms of emotion recognition and alexithymia. In some patients mild signs of anxiety and lowered mood are found that, however, do not meet the criteria for a specific psychiatric disorder. It is concluded that NS in adults is associated with a behavioral phenotype in which deficiencies in social and emotional recognition and expression may be key elements.

Parallelism in Artificial Intelligence Problem Solving: A Case Study of Hearsay II (1977)

The Hearsay II speech-understanding system (HSII) (Lesser et al [11], Fennell [9], and Erman and Lesser [6]) is an implementation of a knowledge-based multiprocessing artificial intelligence (AI) problem-solving organization. HSII is intended to represent a problem-solving organization which is applicable for implementation in a parallel hardware environment such as C.mmp (Bell et al [2]). The primary characteristics of this organization include: 1) multiple, diverse, independent and asynchronously executing knowledge sources (KS's), 2) cooperating (in terms of control) via a generalized form of the hypothesize-and-test paradigm involving the data-directed invocation of KS processes, and 3) communicating (in terms of data) via a shared blackboard-like data base in which the current data state is held in a homogeneous, multidimensional, directed-graph structure. The object of this paper is to explore several of the ramifications of such a problem-solving organization by examining the mechanisms and policies underlying HSII which are necessary for supporting its organization as a multiprocessing system. In addition, a multiprocessor simulation study is presented which details the effects of actually implementing such a parallel organization for use in a particular application area, that of speech understanding.
An Information-Based Time Sequential Approach to Online Incident Duration Prediction (2008)

Online prediction of incident duration (i.e., remaining incident duration) is becoming more important as more intelligent transportation system deployments in the United States focus on improving the operations of transportation management centers. This study proposed a time sequential procedure where an incident management process is divided into stages according to the specific information available. For each stage, a hazard-based duration regression model with different variables representing the available information was developed. By calibrating these models, the parameters of probability distributions assumed for incident duration and the coefficients of the variables were jointly estimated. Based on the estimated parameters and coefficients, remaining incident duration can be predicted online using the truncated median of incident duration. This study concluded that the accuracy of the prediction of incident duration increases as more information is incorporated into the developed models. The prediction based on the truncated median is more accurate than that based on the truncated mean because the probability distribution of incident duration has a long tail. The proposed procedure provides flexibility for implementation in the real world.
Ruthenium-Red-Stained Anionic Charges of Rat and Mice Mesothelial Cells and Basal Lamina: The Peritoneum Is a Negatively Charged Dialyzing Membrane (1988)

The peritoneum has been classically considered to be an inert passive membrane. Previous studies demonstrated the presence of fixed anionic charges at the level of the peritoneal microvasculature and the subserosal interstitium. The present study describes the selective distribution of fixed anionic charges in the mesothelial cell plasmalemma and organelles as well as in the submesothelial basal lamina of rat and mice visceral, parietal and diaphragmatic peritoneum. These data support the idea that the peritoneum should be considered a negatively charged biological dialyzing membrane with selective capabilities. Therefore, transperitoneal transfer of charged solutes cannot be analyzed just on the basis of their molecular weight, size and shape.

A Comparative Study on Malay and Chinese Accounting Students’ Perceptions on Accounting Career (2009)

Using questionnaire survey, this study examines accounting students’ attitude on accounting career. Specifically, this study examines whether there is any significant difference on the accounting students’ attitude of accounting career caused by cultural differences as differentiated by race. Two large groups of races in Malaysia were chosen: Malay students and Chinese students. The results show a significance difference in accounting career choice between the Malay students and the Chinese students. Further results show that there are significant differences between the two groups on the important criteria in salary determination in terms of qualification and work performance. However, both groups agree that interest and job responsibilities are not important factors for an accountant. The results provide useful insights to relevant institutions in formulating plans in their institutions in alleviating differences caused by cultural differences on students’ attitude on accounting career and therefore, produce highly competitive graduates. Keywords: Malay; Chinese; accounting students; attitude; accounting career Resume: En utilisant la methode de l’enquete par questionnaire, cette etude examine les perceptions de la carriere de comptable des etudiants en comptabilite. Plus precisement, cette etude examine s'il existe une difference significative sur les perceptions de la carriere de comptable causes par les differences culturelles chez les etudiants en comptabilite. Deux grands groupes de race en Malaisie ont ete choisis: les etudiants malaisiens et les etudiants chinois. Les resultats montrent une difference importante dans le choix de la carriere de comptable entre les etudiants malaisiens et les etudiants chinois.
