End Temperature Prediction of Molten Steel in LF Based on CBR (2012)

Abstract In order to improve the temperature control level of molten steel in ladle furnace (LF), a case‐based reasoning (CBR) method has been proposed for predicting end temperature of molten steel in LF. To predict the temperature accurately and efficiently, this paper develops two‐step retrieval approach and the correlation based feature weighting (CFW) method for CBR. And, the study evaluates the prediction effect of CBR method by the experiment of comparison with back propagation neural network (BPNN) model and CBR model. Experimental results show that CBR model achieves better accuracy than BPNN model and the CBR method is effective to predict end temperature of molten steel in LF.
Partial discharge location on power cables using linear prediction (2002)

In this paper a linear prediction technique is developed to separate a partial discharge signal from its echoes in a noisy environment. Based on the correlation which exists between the measuring values of a signal, it is possible to trace the signal. The signal can then be extracted from its echoes or background noise. Since the parameters of the prediction technique are determined by the recorded signal, very good results can be obtained from a noisy composite signal. This procedure can provide a good method to filter a composite signal when conventional methods fail.
A comparative study of the morphology and wetting characteristics of micro/nanostructured Cu surfaces for phase change heat transfer applications (2012)

A comparative study of oxidation methods to create Cu surfaces with controlled wettability is reported. Micro/nanostructures of Cu oxides are formed on Cu substrates using different chemical and thermal oxidation methods. The morphology and wetting characteristics of the resulting surfaces are characterized using atomic force microscopy, scanning electron microscopy, X-ray diffraction, and contact angle measurements. Chemical oxidation in alkali solutions can form uniform copper oxide layers with high roughness factors without causing thermal stress problems that often hamper thermal oxidation. By combining chemical oxidation with a hydrophobic coating, a wide range of wettability control is demonstrated from superhydrophilic ( < 10°) to superhydrophobic ( > 170°). Superhydrophilic CuO layers uniformly formed on Cu powder and Cu micropost wick surfaces lead to significant improvement in the capillary and heat transfer performance compared with comparable unoxidized Cu wicks. The present work motivates further studies to exploit the benefits of nanostructured Cu surfaces in various phase change heat transfer applications.
Recursive Receiver Down-Converters With Multiband Feedback and Gain-Reuse (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Receiver down-converter topologies are presented that provide simultaneous frequency conversion and baseband amplification within a mixer, in order to reduce power dissipation for a given dynamic range. The down-converted IF output of a mixer is reapplied to its input stage in a recursive manner, which significantly enhances the conversion gain, with current requirement determined primarily by the input transconductor of the mixer. Two down-converter topologies based on this technique are presented. One topology utilizes common-source NMOS devices as the RF input stage of the mixer, and reuses their transconductance for providing baseband gain. The second topology utilizes differential pairs as the RF input stage, and employs the transconductance of the tail current-source devices for baseband gain. The designs are implemented in a 0.13-<formula formulatype="inline"><tex>$\mu$</tex></formula>m CMOS technology and achieve peak conversion gains of 50 dB and 56 dB, with single side-band noise figures of 12.7 dB and 9.4 dB, and OIP3 values of 8 <formula formulatype="inline"> <tex>$\hbox{dBV}_{\rm p}$</tex></formula>and 11 <formula formulatype="inline"> <tex>$\hbox{dBV}_{\rm p}$</tex></formula>, respectively.

The active die area is less than 0.1 mm <formula formulatype="inline"><tex>$^{2}$</tex> </formula> for each design. Noise and linearity performance of the down-converters is analyzed, and the potential for enhancement of IIP3 through cancellation of nonlinear products is discussed. </para>

CloudStream: Delivering high-quality streaming videos through a cloud-based SVC proxy (2011)

Existing media providers such as YouTube and Hulu deliver videos by turning it into a progressive download. This can result in frequent video freezes under varying network dynamics. In this paper, we present CloudStream: a cloud-based video proxy that can deliver high-quality streaming videos by transcoding the original video in real time to a scalable codec which allows streaming adaptation to network dynamics. The key is a multi-level transcoding parallelization framework with two mapping options (Hallsh-based Mapping and Lateness-first Mapping) that optimize transcoding speed and reduce the transcoding jitters while preserving the encoded video quality. We evaluate the performance of CloudStream on our campus cloud testbed.

Osteopontin Expression in Normal Skin and Non-melanoma Skin Tumors (2007)

Osteopontin (OPN) is an adhesive, matricellular glycoprotein, whose expression is elevated in many types of cancer and has been shown to facilitate tumorigenesis in vivo. To understand the role of OPN in human skin cancer, this study is designed to determine whether OPN is expressed in premalignant [solar/actinic keratosis (AK)] and in malignant skin lesions such as squamous cell carcinomas (SCC) and basal cell carcinomas (BCC), as well as in normal skin exposed or not exposed to sunlight. Immunohistochemical analyses showed that OPN is expressed in SCC (20/20 cases) and in AK (16/16 cases), which are precursors to SCC, but is absent or minimally expressed in solid BCC (17 cases). However, positive staining for OPN was observed in those BCC that manifest differentiation toward epidermal appendages such as keratotic BCC. In sunlight-exposed normal skin, OPN is minimally expressed in the basal cell layer, but in contrast to those not exposed to sunlight, OPN is more prominent in the spinous cell layer with increasing intensity toward the granular cell layer. Additionally, OPN is expressed in the hair follicles, sebaceous glands, and sweat glands of normal skin. In conclusion, these data suggest that OPN is associated with keratinocyte differentiation and that it is expressed in AK and SCC, which have metastatic potential, but minimally expressed in solid BCC.
MINCE: A Static Global Variable-Ordering for SAT and BDD (2001)

Abstract: The increasing popularity of SAT and BDD techniques in formal hardware verification and automated synthesis of logic circuits encourages the search for additional speedups. Since typical SAT and BDD algorithms are exponential in the worst-case, the structure of realworld instances is a natural source of improvements. While SAT and BDD techniques are often presented as mutually exclusive alternatives, our work points out that both can be improved via the use of the same structural properties of instances. Our proposed methods are based on efficient problem partitioning and can be easily applied as pre-processing with arbitrary SAT solvers and BDD packages without modifying the source code of SAT/BDD tools. Finding a better variable ordering is a well recognized problem for both SAT solvers and BDD packages. Currently, the best variable-ordering algorithms are dynamic, in the sense that they are invoked many times in the course of the host algorithm that solves SAT or manipulates BDDs. Examples include the DLCS ordering for SAT solvers and variable sifting during BDD manipulations. In this work we propose a universal variable-ordering algorithm MINCE (MIN Cut Etc.) that pre-processes a given Boolean formula in CNF. MINCE is completely independent from target SAT algorithms and in some cases outperforms both the variable state independent
LEAP+ (2006)

We describe LEAP+ (Localized Encryption and Authentication Protocol), a key management protocol for sensor networks that is designed to support in-network processing, while at the same time restricting the security impact of a node compromise to the immediate network neighborhood of the compromised node. The design of the protocol is motivated by the observation that different types of messages exchanged between sensor nodes have different security requirements, and that a single keying mechanism is not suitable for meeting these different security requirements. LEAP+ supports the establishment of four types of keys for each sensor node: an individual key shared with the base station, a pairwise key shared with another sensor node, a cluster key shared with multiple neighboring nodes, and a global key shared by all the nodes in the network. LEAP+ also supports (weak) local source authentication without precluding in-network processing. Our performance analysis shows that LEAP+ is very efficient in terms of computational, communication, and storage costs. We analyze the security of LEAP+ under various attack models and show that LEAP+ is very effective in defending against many sophisticated attacks, such as HELLO flood attacks, node cloning attacks, and wormhole attacks. A prototype implementation of LEAP+ on a sensor network testbed is also described.

Induced Pluripotent Stem Cells and Erythrocyte Production (2012)

Abstract Abstract SCI-38 Induced pluripotent stem cells (iPSCs) are somatic cells that have been turned into embryonic-like stem cells by forced expression of factors critical for establishing pluripotency. Because iPSCs can be differentiated into any type of cell in the human body, including hematopoietic cells, they are seen as a logical alternative source of red blood cells (RBCs) for transfusion. In addition, the unlimited expansion potential of iPSCs makes it easy to adopt iPSC technology for RBC biomanufacturing. iPSCs can be generated from any type of donor, including O/Rh-negative universal donors and donors with very rare blood phenotypes, which makes it possible to generate blood products to accommodate virtually all patient groups. We have developed an approach for generating large quantities of RBCs from iPSCs by inducing them to differentiate into CD34+CD43+ hematopoietic progenitors in coculture with OP9 stromal cells, followed by selective expansion of erythroid cells in serum-free media with erythropoiesis-supporting cytokines. Erythroid cultures produced by this approach consist of leukocyte-free populations of CD235a+ RBCs with robust expansion potential and long (up to 90 days) life spans. In these cultures, up to 1.8×105 RBCs can be generated from a single iPSC. Similar to embryonic stem cells, iPSC-derived RBCs express predominantly embryonic and fetal hemoglobin, with very little adult hemoglobin. It is already feasible to adopt iPSC technologies for producing cGMP-grade RBCs using defined animal-product-free differentiation conditions. However, the induction of the complete switch from embryonic to fetal and adult hemoglobin, as well as the terminal maturation and enucleation of iPSC-derived erythroid cells, remains a significant challenge. We recently identified at least three distinct waves of hematopoietic progenitors with erythroid potential in iPSC differentiation cultures. The characterization of erythroid cells produced from these waves of hematopoiesis may help to define populations with definitive erythroid potential and facilitate the production of erythrocytes from iPSCs. Additional critical steps toward translating iPSC-based RBC technologies to the clinic include the development of bioreactor-based-technology for further scaling-up of cell production, and evaluation of the therapeutic potential and safety of human pluripotent stem cell-derived blood cells in animal models. Overall, the manufacturing of RBCs provides several advantages. It can improve the continuity of the blood supply, minimize/eliminate the risk of infection transmission, reduce the incidence of hemolytic and nonhemolytic transfusion reactions, and provide an opportunity to generate RBCs that fit specific clinical needs by using genetically engineered iPSCs or iPSCs with rare blood groups.

Dynamic Changes in the Intrafollicular Inhibin/Activin/Follistatin Axis during Human Follicular Development: Relationship to Circulating Hormone Concentrations* (2000)

Previous studies of normal human ovaries suggest that inhibins, activins, and follistatin (FS) are produced in a stage-specific pattern indicative of intraovarian, autocrine/paracrine roles in regulating follicle development. However, these studies relied largely on surgical specimens and thus include little information about the menstrual cycle stage or dominant follicle status at the time follicles or ovaries were obtained. The purpose of this study was to 1) determine the pattern of intrafollicular hormone biosynthesis across antral follicle development in normal women, 2) compare hormone concentrations in dominant and nondominant follicles from the same ovary, and 3) examine the relationship between dominant follicle hormone content and circulating hormone levels. Intrafollicular estradiol, progesterone, and inhibin A concentrations increased significantly with follicle size or maturity, whereas significant inverse relationships were observed for androstenedione and the androstenedione/estradiol (A:E) ratio. In contrast, neither inhibin B, activin A, nor free FS varied consistently with size or maturity. Estradiol, progesterone, and inhibin A levels and A:E ratio were significantly lower in nondominant follicles compared to the dominant follicle aspirated from the same ovary. Although intrafollicular and serum concentrations of each hormone followed the same general pattern as follicles develop, the human follicular fluid/serum gradients changed during the follicular phase and were different for estradiol and inhibin A, suggesting the presence of stage-specific differences in pharmacodynamics. These results are consistent with the hypothesis that the orderly transition from an activin-dominant to an inhibin A/FS-dominant microenvironment is critical for dominant follicle development.

Designing and implementing a computer learning center in a college of medicine. (1989)

This report describes the approach taken at the Penn State College of Medicine to develop a central Computer Learning Center (CLC) and the use characteristics during the first 21 months of operation. A task force was created to establish the CLC, and a 12-month timetable was used from initial planning until the CLC was operational. In the first 21 months of operation, the CLC use increased linearly from 48 users per month to 388 users per month. More than half of the users were medical students, with the remainder distributed among faculty, staff, graduate students, nursing students, and medical residents. The growth of CLC use and the diversity of computer-assisted applications have occurred due to its central location within the medical center library and to CLC operation being shared by the library and the Department of Educational Resources.

QDB - A Query Processor for the High Performance, Parallel Data Server NDB Cluster (1999)

This report describes a query language front-end developed for the data server NDB Cluster. NDB Cluster is a high-performance, parallel data server that is being developed by Ericsson for telecom applications. The query processor QDB is an extension of the AMOS DBMS with an interface to NDB Cluster. The query language of AMOS, AMOSQL, supports an Object-Relational data model and makes it possible to support both a relational model of data in NDB Cluster, as well as an Object-Oriented (OO) data model. NDB Cluster supports a flat relational data model and QDB supports transparent translation of OO queries to flat relations. QDB utilizes the foreign function mechanism of AMOS which makes it possible to integrate foreign data sources transparently and with an extensible query optimizer. The report describes the translation process, query processing and optimization of QDB queries, and details about the interface between the systems.

Interface-mediated hygroelectric generator with an output voltage approaching 1.5 volts (2018)

Hygroelectricity is proposed as a means to produce electric power from air by absorbing gaseous or vaporous water molecules, which are ubiquitous in the atmosphere. Here, using a synergy between a hygroscopic bulk graphene oxide with a heterogeneous structure and interface mediation between electrodes/materials with Schottky junctions, we develop a high-performance hygroelectric generator unit with an output voltage approaching 1.5 V. High voltage (e.g., 18 V with 15 units) can be easily reached by simply scaling up the number of hygroelectric generator units in series, enough to drive commercial electronic devices. This work provides insight for the design and development of hygroelectric generators that may promote the efficient conversion of potential energy in the environmental atmosphere to electricity for practical applications.
