Evolution of microchannel flow passages – Thermohydraulic performance and fabrication technology

This paper provides a roadmap of development in the thermal and fabrication aspects of microchannels as applied in the microelectronics and other high heat-flux cooling applications. Microchannels are defined as flow passages that have hydraulic diameters in the range of 10 to 200 micrometers. The impetus for microchannel research was provided by the pioneering work of Tuckerman and Pease [1] at Stanford University in the early eighties. Since that time, this technology has received considerable attention in microelectronics and other major application areas, such as fuel cell systems and advanced heat sink designs. After reviewing the advancement in heat transfer technology from a historical perspective, advantages of using microchannels in high heat flux cooling applications is discussed, and research done on various aspects of microchannel heat exchanger performance is reviewed. Single-phase performance for liquids is expected to be still describable by the conventional equations; however the gas flow may be influenced by the rarefaction effects. Two-phase flow is another topic that is still under active research. The evolution of research into microchannel heat sinks has paralleled the advancements made in microfabrication technology. The earliest microchannels were built using anisotropic wet chemical etching techniques based on alkali solutions. While this method has been exploited successfully, it does impose certain restrictions on silicon wafer type and geometry. Recently, anisotropic dry etching processes have been developed that circumvent these restrictions. In addition, dry etching methods can be significantly faster and, from a manufacturing standpoint, create fewer contamination and waste treatment problems. Advances in fabrication technology will continue to fuel improvements in microchannel heat sink performance and cost for the foreseeable future. Some fabrication areas that may spur advances include new materials, high aspect ratio patterning techniques other than dry etching, active fluid flow elements, and micromolding.Copyright © 2002 by ASME
On positivity of time-frequency distributions

This correspondence addresses the problem of how to regard the fundamental impossibility with time-frequency energy distributions of Cohen's class always to be nonnegative and, at the same time, to have correct marginal distributions. It is shown that the Wigner distribution is the only member of a large class of bilinear time-frequency distributions that becomes nonnegative after smoothing in the time-frequency plane by means of Gaussian weight functions with BT product equal to unity.
Kinetics of Antigen-Induced Phenotypic and Functional Maturation of Human Monocyte-Derived Dendritic Cells1

Dendritic cells (DCs), a critical component of innate immunity, are the most potent APCs. When DCs mature, they can elicit strong T cell responses. We studied the kinetics of Ag-induced phenotypic and functional maturation of human monocyte-derived DCs using an in vitro T cell-independent culture system. With this model, we herein show that an Ag that has recently or repetitively been exposed (“exposed Ag”) rapidly induces a high level of maturation; however, an Ag that has never or only remotely been exposed (“unexposed Ag”) slowly induces a low level of maturation. The kinetics of Ag-induced maturation of DCs possibly implies a novel mechanism for immunological memory that would provide maximal host protection from repetitively invading pathogens in the environment.
[Effect of pioglitazone on receptor activator of nuclear factor-kappa B expression in osteoclast from RAW264.7 cells].

OBJECTIVE To study the effect of pioglitazone, a synthetic peroxisome proliferator-activated receptor γ (PPARγ) agonist, on the RANKL-mediated osteoclastogenesis of osteoclast precursor cells, and to explore the function and mechanism of PPARγ in the osteoclast differentiation. METHODS Pioglitazone treatment of RAW264.7 murine macrophages were compared with those of simply cultured control and RANKL-mediated control. Accordingly, the RANKL-mediated cells were cultured with 30 ng/ml RANKL, then induced into significant multinuclear osteoclast formation. And pioglitazone treated cells were exposed to 10 µmol/L pioglitazone during the process of osteoclast differentiation under RANKL. The number of mature osteoclasts was calculated and the mRNA levels of RANK analyzed by real-time quantitative PCR. RESULTS Pioglitazone significantly inhibited osteoclastogenesis of osteoclast precursor cells, the number of mature osteoclasts of pioglitazone treated group was (176 ± 58)/cm(2) and significantly less than the mature cells of RANKL induced group which number was (322 ± 74)/cm(2) (P < 0.01); and pioglitazone also significantly inhibited the mRNA expression of RANK, a typical differentiated factor of osteoclast, the number of the mRNA expression of RANK of pioglitazone treated group was 2.16 ± 0.74 and significantly less than the number of RANKL induced group (4.94 ± 0.39, P < 0.01). CONCLUSION PPARγ agonist inhibited the differentiation of RAW264.7 towards osteoclast. It might be due to the suppression of RANK gene expression in the process of osteoclast differentiation.
Design of beam steering antenna for localization applications

A 2.4 GHz beam steering antenna array is presented and tested in this paper. This antenna uses the 4×4 planar Butler matrix as a key component of phase-shifter which exhibits ±135° and ±45° phase shifts corresponding with four position of main beam. The proposed design is fully described, from the element blocks (antenna element, butler matrix) to the full integrated beam steering antenna array. The proposed antenna has the 20°–27° of beam-width in vertical and 240° of beam-width in horizontal. The main beam of this antenna can steer from −37°, −12°, 12° to +36° in vertical. Simulation results will be presented and compared with experimentation data.
Towards Mobile Collaborative Exergaming

Today’s high calorie diets and low physical activity levels contributes towards childhood obesity. Exergaming, a combination of ”exercise” and ”gaming” was conceived as a means of addressing this problem. In this paper a mobile collaborative exergame, which is designed to be enjoyable and physically challenging, is presented. The long term objective is to harness conventional mobile computing technologies to deliver a platform for games that are adaptive to the exercise requirements of individual children.
A Double-Efficient Integrity Verification Scheme to Cloud Storage Data

This paper proposed two integrity verification schemes based on Schnorr Signature Scheme. One is safety integrity verification scheme (SIVS). Another is efficient integrity verification scheme (EIVS). They are difference in characteristics. EIVS has good computational costs while SIVS has high security guarantee. However, they are similar in work. The cloud storage server will choose a set of file blocks and verification blocks randomly while the user sends a challenge, and generate response values to send to the user. The user generates a set of signatures to verify the values. The aim is to check whether the cloud storage server preserves perfectly the user's file or not. In contrast with other schemes, the approach not only has double integrity verification guarantee schemes but also pay lower costs for communication and computation.
Creating a transloxation

The site‐specific recombinases (SSRs), Cre and FLP, have added a variety of possibilities to the field of genome engineering. Two articles in this issue of EMBO Reports (Buchholz et al ., 2000; Collins et al ., 2000) now extend the repertoire of SSR‐driven genomic alterations in the mouse by adding possibly the most difficult task ever asked of these enzymes, namely translocation between non‐homologous chromosomes. Aiming at establishing better mouse models of human leukemias, the two groups introduced loxP sites into the mouse at the relevant positions on two chromosomes and show that, upon Cre expression, it is possible to detect the heterologous translocation at reasonable frequencies. Although FLP‐mediated translocation between homologous chromosomes in Drosophila was one of the first applications of site‐specific recombination in genome engineering (Golic, 1991), the findings reported in this issue were by no means an expected advance along a linear pathway. Scepticism had lingered over the possibility that an SSR‐driven non‐homologous translocation could be achieved in the mouse at a detectable frequency. It was clear from other (‘easier’) genome engineering exercises that efficiency dropped as a function of the …

Eye Trauma Epidemiology in Regional Australia

Abstract Purpose: To describe the epidemiology of eye trauma presenting to a regional referral health service in New South Wales, Australia. Methods: A two-stage retrospective and prospective case series study was conducted. Patients who presented with eye trauma to Wagga Wagga Base Hospital (WWBH) emergency department (ED) during a one-year review period formed the retrospective case series (RCS). Patient inclusion was determined using Systematized Nomenclature of Medicine Clinical Terms and International Classification of Diseases 10th revision codes applied to medical records. Patients presenting with eye trauma to the WWBH ED or its ophthalmology service over a prospective 80-day study period formed the prospective case series (PCS). The main outcome measures were patient demographics, eye trauma incidence for Wagga Wagga and the Murrumbidgee region and injury details. Results: A total of 411 and 117 eye injuries were identified for the RCS and PCS, respectively. Mean age was 35.5 ± 18.6 years (RCS) and 34.1 ± 17.1 years (PCS), with male predominance (77.9%, RCS; 89.7%, PCS). The incidence of eye trauma in Wagga Wagga and Murrumbidgee was estimated from the PCS at 537.1 and 334.4, respectively, per 100,000 person-years. A large proportion of injuries were work-related (40.2% RCS, 45.8% PCS). Protective eyewear use in work-related injuries was low (27.6% RCS, 39.0% PCS). Conclusions: Eye trauma remains a significant public health concern with a high incidence in Wagga Wagga and the Murrumbidgee region. Protective eyewear compliance is low in work-related eye injuries. Patient demographic and occupational factors may be targeted to reduce the burden of disease.
On the impact of covariate measurement error on spatial regression modelling

Spatial regression models have grown in popularity in response to rapid advances in geographic information system technology that allows epidemiologists to incorporate geographically indexed data into their studies. However, it turns out that there are some subtle pitfalls in the use of these models. We show that the presence of covariate measurement error can lead to significant sensitivity of parameter estimation to the choice of spatial correlation structure. We quantify the effect of measurement error on parameter estimates and then suggest two different ways to produce consistent estimates. We evaluate the methods through a simulation study. These methods are then applied to data on ischaemic heart disease. Copyright © 2014 John Wiley & Sons, Ltd.
Delivering 3D advertising to mobile phones

Directing advertising to mobile phones currently is limited to commercial text messages, short-code text-back messages, two dimensional (2D) images, or wireless access protocol (WAP) clickable push links. All of these traditional methods do not facilitate advertising approach were consumers can interact with prospective purchases. In this paper we introduce a novel and highly interactive location- and permission-based advertising system that allows 3D product adverts to be displayed on users' mobile phones. The paper provides a thorough discussion of the system covering its performance, implementation structure, platform-dependent optimizations and suggestions for future work. With mobile phones and 3D interactive tools, advertising becomes more engaging, rewarding and entertaining and provides marketing executives with new means of directing their campaigns to a more specific target audience.
2-D adaptive state-space digital filters using LMS algorithm

This paper treats the realization of 2-D adaptive state-space filters using the least mean squares (LMS) algorithm. This is based on the Roesser local state-space model. First, the relation between the coefficient sensitivities and the intermediate transfer functions is investigated. Then, after introducing new systems for generating the gradient vectors, an adaptive algorithm is developed using the LMS algorithm. Finally, in a numerical example the 2-D adaptive state-space filter is used to design a 2-D digital filter in the spatial domain. <<ETX>>
An Analytical Method for Linear Combining with Application to FFH NCFSK Receivers

A method for obtaining the probability density function (PDF) and the cumulative density function (CDF) of sum-independent random variables is presented. The method is capable of determining the PDF and CDF of this sum for an input consisting of any combination of a signal tone, white Gaussian noise, and multiple interfering tones. It is based upon circularly symmetric function theory, Fourier-Bessel series, and Fourier series. To illustrate this method, applications are presented for a fast frequency-hopped noncoherent frequency-shift-keyed communications system. From the PDF and CDF of the received signal, performance values such as the error probability for demodulation, the probability of detection and false alarm for coarse-time synchronization and the mean and variance of timing-error estimates for fine-time synchronization are obtained. >
Teachers' support using interaction analysis and visualization tools in educational group blogging

Blogging is quite popular and group blogging has interesting potential for collaborative learning. This paper investigates the possibility of implementing Interaction Analysis techniques in educational group-blogging systems, as a tool for supporting teachers especially for engineering education. The main objective of the pilot study is to provide evidence that teachers could be facilitated, in the process of evaluating and assessing students' interaction and participation, through an Interaction Analysis plugin developed for the WordPress blogging platform. Overall, preliminary findings indicate that the prototype WordPress plugin and its integrated Interaction Analysis indicators, described in this paper, can significantly assist teachers in evaluating collaborative learning activities under the scope of engineering education.
Language-level persistency

The commercial release of byte-addressable persistent memories, such as Intel/Micron 3D XPoint memory, is imminent. Ongoing research has sought mechanisms to allow programmers to implement recoverable data structures in these new main memories. Ensuring recoverability requires programmer control of the order of persistent stores; recent work proposes persistency models as an extension to memory consistency to specify such ordering. Prior work has considered persistency models at the abstraction of the instruction set architecture. Instead, we argue for extending the language-level memory model to provide guarantees on the order of persistent writes. We explore a taxonomy of guarantees a language-level persistency model might provide, considering both atomicity and ordering constraints on groups of persistent stores. Then, we propose and evaluate Acquire-Release Persistency (ARP), a language-level persistency model for C++11. We describe how to compile code written for ARP to a state-of-the-art ISA-level persistency model. We then consider enhancements to the ISA-level persistency model that can distinguish memory consistency constraints required for proper synchronization but unnecessary for correct recovery. With these optimizations, we show that ARP increases performance by up to 33.2% (19.8% avg.) over coding directly to the baseline ISA-level persistency model for a suite of persistent-write-intensive workloads.
PelX is a UDP-N-acetylglucosamine C4-epimerase involved in Pel polysaccharide–dependent biofilm formation

Pel is a GalNAc-rich bacterial polysaccharide that contributes to the structure and function of Pseudomonas aeruginosa biofilms. The pelABCDEFG operon is highly conserved among diverse bacterial species, and Pel may therefore be a widespread biofilm determinant. Previous annotation of pel gene clusters has helped us identify an additional gene, pelX, that is present adjacent to pelABCDEFG in >100 different bacterial species. The pelX gene is predicted to encode a member of the short-chain dehydrogenase/reductase (SDR) superfamily, but its potential role in Pel-dependent biofilm formation is unknown. Herein, we have used Pseudomonas protegens Pf-5 as a model to elucidate PelX function as Pseudomonas aeruginosa lacks a pelX homologue in its pel gene cluster. We found that P. protegens forms Pel-dependent biofilms; however, despite expression of pelX under these conditions, biofilm formation was unaffected in a ΔpelX strain. This observation led us to identify a pelX paralogue, PFL_5533, which we designate here PgnE, that appears to be functionally redundant to pelX. In line with this, a ΔpelX ΔpgnE double mutant was substantially impaired in its ability to form Pel-dependent biofilms. To understand the molecular basis for this observation, we determined the structure of PelX to 2.1 Å resolution. The structure revealed that PelX resembles UDP-GlcNAc C4-epimerases. Using 1H NMR analysis, we show that PelX catalyzes the epimerization between UDP-GlcNAc and UDP-GalNAc. Our results indicate that Pel-dependent biofilm formation requires a UDP-GlcNAc C4-epimerase that generates the UDP-GalNAc precursors required by the Pel synthase machinery for polymer production.
An Intelligent Approach for the Effect of Social Media on Undergraduate Students Performance: A Case Study in the University of Jordan

Promoting the learning environment within Jordanian universities and maximizing the students' academic gain are essential national-level problems. Since learning and teaching systems are main building bricks to grow individuals who are responsible for developing and flourishing culture and civilization for Jordanian society. Educational data mining focuses on developing new smart algorithms devoted to analyzing the resulted data from educational systems; in order to better understand students and the learning environments. In this paper, we are analyzing major factors affecting university students' performance and the effect of social media usage on them. Furthermore, predicting the students' performance by adopting different rule-based data mining algorithms like rule learner based on Repeated Incremental Pruning to Produce Error Reduction (JRIP) and a type of decision tree called (PART). We have conducted a research survey within the University of Jordan students that is covering all faculties and cover a vast range of different students. Using both JRIP and PART we have concluded fundamental remarks; mainly, we have noticed that using YouTube as a learning resource has positive impacts on students' performance especially within scientific faculties. Moreover, we have interpreted the impact of other factors, such as having an Internet connection, having several social media applications and others. Certainly, upon our findings, we recommend the importance of integrating YouTube as a learning resource within universities learning environments.
Kinematics and optimal design of a novel 3-DoF parallel manipulator for pick-and-place applications

In this paper, a novel 3-degree-of-freedom planar parallel manipulator, the V3 robot, is introduced. The manipulator consists of three revolute joint) subchains, which are respectively arranged in three-parallel planes. The three-actuated joints are designed to have a common rotation axis, which contributes the large workspace and unlimited rotational capability of the robot. The kinematics, including the loop-closure equations, the inverse kinematics, singularity, and workspace are briefly analysed. By directly considering the velocity and the accuracy indices for pick and place operations, the optimal design problem is formulated to maximise the good performance workspace, where lower bounds on the average extreme velocity and upper bounds on the average extreme error are applied as constraints. The optimal design shows greatly improved performance in workspace, velocity, and accuracy.
A New Simple Order-Based Multiple Access Scheme

A new adaptive multiple access scheme based on the theory of order statistics is introduced. Because the proposed low-complexity method requires relatively small channel information overhead and processing delays, it can be feasible in fast-fading environments and systems with large number of users. Numerical results reveal significant system performance improvement over conventional approaches.
