Heat Transfer and Economic Analysis of Seawater-Source Heat Pump System with Casted Heat Exchanger

There is an increasing trend in using seawater-source heat pump system (SWHP) in heating and air conditioning systems of commercial and residential buildings in coastal cities in China. This paper established a heat transfer model for casted heat exchanger (CHE) adopted by SWHP systems in winter and summer mode. The CHE was consisted of pipes immersed in the seawater and used for transferring heat between the seawater and the heat exchanger pipes of SWHP system. An experimental study was carried out to test the validity of the model. An office building, located in Tianjin Port, near the 30 thousand ton oil terminal was described. The economic, energy and environmental impacts were compared between the two systems. In conclusion, the results shown the SWHP system with CHE was able to reduce the power consumption and air pollution emissions. It was demonstrated that the use of ocean thermal energy in Tianjin shown a promising prospect in the near future and had great potential for development in coastal cities in China.
Denaturing-HPLC-based assay for detection of ABL mutations in chronic myeloid leukemia patients resistant to Imatinib.

BACKGROUND Despite the efficacy of the BCR-ABL tyrosine kinase inhibitor Imatinib mesylate for the treatment of chronic myeloid leukemia (CML), resistance has been observed in a proportion of cases, especially those with advanced stages of the disease. Point mutations within the ABL kinase domain are emerging as the most frequent mechanism for reactivation of kinase activity within the leukemic clone. METHODS We developed a denaturing-HPLC (D-HPLC)-based assay for screening for ABL point mutations. For each sample, two partially overlapping fragments of 393 and 482 bp corresponding to the kinase domain were amplified by nested reverse transcription-PCR and analyzed under selected temperature and acetonitrile gradient conditions. Fifty-one bone marrow and/or peripheral blood specimens from 27 CML patients who showed cytogenetic resistance to Imatinib were screened in parallel by D-HPLC and by direct sequencing. RESULTS In 12 of 27 (44%) patients, D-HPLC showed an abnormal elution profile suggesting the presence of a nucleotide change. Direct sequencing confirmed the presence of a point mutation in all cases. Conversely, all samples scored as wild type by D-HPLC showed no evidence of mutations by direct sequencing. In two cases, novel amino acid substitutions at codons already known for being hot-spots of mutation were identified (F311I and E355D). CONCLUSIONS The proposed D-HPLC-based assay is highly specific and at least as sensitive as sequencing; with respect to the latter, it provides a much faster and less expensive semiautomated system for mutational screening. It may therefore potentially be a valuable tool for regular, large-scale testing of patients undergoing Imatinib treatment.
Color image processing pipeline

Digital still color cameras (DSCs) have gained significant popularity in recent years, with projected sales in the order of 44 million units by the year 2005. Such an explosive demand calls for an understanding of the processing involved and the implementation issues, bearing in mind the otherwise difficult problems these cameras solve. This article presents an overview of the image processing pipeline, first from a signal processing perspective and later from an implementation perspective, along with the tradeoffs involved.
Gender vis-à-vis perceptions of Fundamental Moral Orientations and outcome preferences

This paper explores the connection between three perceived Fundamental Moral Orientations (FMOs) and three perceived outcome preferences for men and women working in the Turkish hotel industry. Specifically, the study aims to investigate the relationships between the perceived FMOs of selfishness, self-fullness, and selflessness, and the perceived outcome preferences of serving personal, customer, and organizational interests. Additionally, the study examines whether gender influences either the perceived outcome preferences of hotel personnel or the FMO/outcome relationships. Based on data from 682 surveys, the FMO/outcome relationships and gender differences in those relationships are tested with correlation analysis; also gender effects and gender differences in the outcome orientations are explored with the single sample t-test and one-way MANOVA, respectively. Some gender effects and/or gender differences exist in each set of results. The mutual theoretical implications of the FMO/outcome relationship results and the outcome preference results are discussed, as are potential managerial implications for the Turkish hotel industry.
Mobile Laser Scanning Systems for Measuring the Clearance Gauge of Railways: State of Play, Testing and Outlook

The paper contains a survey of mobile scanning systems for measuring the railway clearance gauge. The research was completed as part of the project carried out for the PKP (PKP Polish Railway Lines S.A., Warsaw, Poland) in 2011–2013. The authors conducted experiments, including a search for the latest solutions relating to mobile measurement systems that meet the basic requirement. At the very least, these solutions needed to be accurate and have the ability for quick retrieval of data. In the paper, specifications and the characteristics of the component devices of the scanning systems are described. Based on experiments, the authors did some examination of the selected mobile systems to be applied for measuring the clearance gauge. The Riegl (VMX-250) and Z+F (Zoller + Fröhlich) Solution were tested. Additional test measurements were carried out within a 30-kilometer section of the Warsaw-Kraków route. These measurements were designed so as to provide various elements of the railway infrastructure, the track geometry and the installed geodetic control network. This ultimately made it possible to reduce the time for the preparation of geodetic reference measurements for the testing of the accuracy of the selected systems. Reference measurements included the use of the polar method to select profiles perpendicular to the axis of the track. In addition, the coordinates selected were well defined as measuring points of the objects of the infrastructure of the clearance gauge. All of the tested systems meet the accuracy requirements initially established (within the range of 2 cm as required by the PKP). The tested systems have shown their advantages and disadvantages.
Automatic generation of diagnostic March tests

A new approach to automatically generating diagnostic memory tests of linear order (/spl Oscr/(N)) is presented. The resulting March tests provide complete detection and distinguishing of all single-cell and two-cell fault models. The approach is based on state transition graph modelling, decomposition of functional memory faults into basic fault effects, and output tracing. For each of the targeted basic fault effects, all possible March sequences are generated. A fast greedy-based algorithm is then used to compose diagnostic March tests from the set of March sequences. The proposed test generation algorithm was implemented in C. The results show that automatic generation can compete with hand-optimization of diagnostic March tests.
Conserved factors Ryp2 and Ryp3 control cell morphology and infectious spore formation in the fungal pathogen Histoplasma capsulatum

The human fungal pathogen Histoplasma capsulatum grows in a sporulating filamentous form in the soil and, after inhalation of infectious spores, converts to a pathogenic yeast form inside host macrophages in response to temperature. Here we report the identification of two genes (RYP2 and RYP3) required for yeast-phase growth. Ryp2 and Ryp3 are homologous to each other and to the Velvet A family of regulatory proteins in Aspergillus species and other filamentous fungi. Wild-type H. capsulatum grows as filaments at room temperature and as yeast cells at 37°C, but ryp2 and ryp3 mutants constitutively grow as filaments independent of temperature. RYP2 and RYP3 transcripts accumulate to higher levels at 37°C than at room temperature. This differential expression is similar to the previously identified RYP1 transcript, which encodes a transcriptional regulator required for the yeast-phase expression program. Ryp1 associates with the upstream region of RYP2, and each of the three RYP genes is required for the differential expression of the others at 37°C. In addition to responding to the elevated temperature of the mammalian host, RYP2 and RYP3 are essential for viable spore production and regulation of sporulation at room temperature. This regulatory function is strikingly similar to the role of the Aspergillus Velvet A protein family in spore development in response to light, with the notable distinction that the H. capsulatum circuit responds to temperature.
User self-controllable profile matching for privacy-preserving mobile social networks

Personal profiles usually contain sensitive information of people, while the emerging requirement of profile matching in mobile social networks may occasionally leak the sensitive information and hence violate people' privacy. In this paper we propose a user self-controllable profile matching protocol in privacy-preserving mobile social networks. By using our protocol, users can customize the matching metrics to involve their own matching preference and to make the matching results more precise. In addition, detailed security analysis demonstrates that our protocol can protect the privacy of both users' profile item names and profile item values during the matching process. Moreover, extensive performance evaluation are conducted to illustrate that our protocol is more efficient than a relevant protocol in terms of computation and communication overhead, especially when the maximum value of profile item is large.
R-SpaRCS: An algorithm for foreground-background separation of compressively-sensed surveillance videos

Detection, recognition and tracking are three of the primary tasks involved in surveillance video processing. Given the huge amount of data generated by surveillance systems, it is desirable to use compressed sensing based techniques for acquisition and subsequent processing of videos. For compressively-sensed videos, the task of object detection can be formulated as a matrix decomposition problem, namely, that of decomposing the video volume matrix into a low-rank background and a sparse foreground matrix from a small set of linear measurements corresponding to the video volume matrix. In this paper, we introduce a regularized version of the SpaRCS algorithm, which is a greedy algorithm for solving problems of the above kind. The proposed algorithm, Regularized-SpaRCS (R-SpaRCS), exploits the fact that the foreground component in natural videos exhibits connectedness. R-SpaRCS is a model-based greedy algorithm that takes into account the connectedness of the support of the sparse foreground component in videos. Experiments performed on surveillance video datasets show that R-SpaRCS achieves a given recovery RSNR faster than the SpaRCS algorithm.
LSM: perceptually accurate line segment merging

Abstract. Existing line segment detectors tend to break up perceptually distinct line segments into multiple segments. We propose an algorithm for merging such broken segments to recover the original perceptually accurate line segments. The algorithm proceeds by grouping line segments on the basis of angular and spatial proximity. Then those line segment pairs within each group that satisfy unique, adaptive mergeability criteria are successively merged to form a single line segment. This process is repeated until no more line segments can be merged. We also propose a method for quantitative comparison of line segment detection algorithms. Results on the York Urban dataset show that our merged line segments are closer to human-marked ground-truth line segments compared to state-of-the-art line segment detection algorithms.
Deflection Behavior of Prestressed Concrete Beam using Fiber Reinforced Polymer (FRP) Tendon

The application of prestressing steel is restricted in highly corrosive environment area. The behavior of structure changes due to corrosion of prestressing steel, which leads to reduction in strength and it may cause sudden failure. There are many research recommendations to resist corrosion of steel, however the durability of structure shall not be ensured during service life of structure. Fiber Reinforced Polymer (FRP) Tendon is considered as an alternate material due to its corrosive resistance property and high strength. An experimental and numerical analysis carried out to study the deflection behavior of FRP tendon prestressed beam and recommended design guidelines. There are four beam specimens casted and tested in laboratory and 51 experimental results collected from research article to carry out numerical study. The ACI, 2011 [1] recommended generalized deflection calculation for beam by softening the effective moment of inertia curve and also introduced the effect of shift of neutral axis once the member exceeds cracking stress of concrete. Based on experimental and numerical analysis study it is concluded that, the deflection behavior of FRP tendon beam depends on deformability of material, degree of prestressing and bond strength. Design chart proposed for calculation of effective moment of inertia and effective neutral axis distance with respect to deformability index. The error percentage of deflection values as per ACI 2011, is about 10 to 20% has reduced to less than 5% in the proposed method.
Investigating gender within health research is more than sex disaggregation of data: A Multi-Facet Gender and Health Model

The aim of this article is to contribute to the further improvement of research in the area of gender and health. First, a review is given of several points of criticism regarding the ways in which gender issues are dealt with in health research. Second, a model, the Multi-Facet Gender and Health Model, is presented which describes the various relationships between biological sex, gender, health, and some moderating variables in between. The model incorporates the complex and multiple ways in which gender as well as sex influence outcome variables in the domain of health research. Third, some methodological issues related to the changing conceptualization of gender are discussed, together with their implications for health research.
Combined Bone Mesenchymal Stem Cell and Olfactory Ensheathing Cell Transplantation Promotes Neural Repair Associated with CNTF Expression in Traumatic Brain-Injured Rats

This study examined the role of bone mesenchymal stem cell (BMSC) and olfactory ensheathing cell (OEC) cografting on neural function and underlying molecular mechanisms in acute stage of traumatic brain injury (TBI) rats. Eighty Sprague-Dawley (SD) female rats were randomly divided into five groups (n = 16 per category): sham operated group (Sham), weight-drop-induced TBI group (TBI), BMSC transplantation group (BMSC), OEC transplantation group (OEC), and cotransplantation group (CO). Eight rats were randomly selected from each group for behavioral and morphological assessment. Another category (n = 8 rats) was employed in the genetic expression detection. BMSCs were isolated from GFP mice and identified by CD44 antibody. OECs were isolated from the SD rats, identified by P75 antibody and labeled by Hoechst 33342. They were then transplanted into the surrounding tissue of the epicenter of TBI rats. The result of neurological severity scores revealed that BMSC or OEC transplantation alone and BMSC and OEC cografting significantly ameliorated the neurological deficits of TBI rats. Quantitative immunohistochemical analysis showed that graft-recipient animals possessed dramatically more neurons and regenerated axons and smaller amounts of astrocytes than controls 14 days posttransplantation (p <0.05). However, the expressional level of ciliary neurotrophic factor significantly decreased in the cografting group as determined by RT-PCR (p <0.05), and the Janus kinase/signal transducer and activator of transcription pathway was significantly activated at 7 days after cell transplantation (p <0.05). This study is the first to report the role of cotransplantation of BMSCs and OECs in the therapy of TBI and explore its potential molecular mechanisms, therefore providing the important morphological and molecular biological evidence for the clinical application of BMSC and/or OEC transplantation in TBI.
The expression of ERCC1 and BRCA1 predicts prognosis of platinum-based chemotherapy in urothelial cancer

Objective To investigate the expression and clinical significance of ERCC1 and BRCA1 genes in urothelial cancer patients. Methods Forty-two urothelial cancer patients who did not receive platinum-based chemotherapy during January 2009 to May 2013 were enrolled. The expression levels of ERCC1 and BRCA1 were determined by immunohistochemistry and the median survival time (MST) for these patients was calculated. Results ERCC1-positive patients who received oxaliplatin-based chemotherapy had a shorter MST than ERCC1-negative patients (P<0.05), whereas there is no difference of MST between BRCA1-positive and -negative patients. Furthermore, MST in ERCC1 and BRCA1 double-positive patients was shorter than ERCC1 and BRCA1 double-negative patients (P<0.05). The positive expression of ERCC1 had a significant positive correlation with BRCA1 (r=0.313, P=0.044). Conclusion The expression level of ERCC1 may be used as a prognostic marker for urothelial cancer patients who received postoperative adjuvant chemotherapy.
An amplifier-doubler chain with conversion gain improvement techniques

: This paper presents an ampli ﬁ er-douler chain to double the signal frequency from 21 GHz to 42 GHz with about 10 GHz bandwidth of output frequency. For the improvement of conversion gain, the doubler adopts the fully di ﬀ erential Gilbert structure which provides large bandwidth and high conversion gain. Meanwhile, an inductive series LC network is used to form resonant tank with the parasitic capacitance to suppress the second harmonic of input frequency, hence the conversion gain of doubler is improved. Once again, the RLC parallel resonant network is employed as load of doubler and power ampli ﬁ er, and it can improve bandwidth and conversion gain, too. What ’ s more, transformer matching networks (TMN) are adopted to optimize the bandwidth and conversion gain of ampli ﬁ er-douler chain. Finally, the ampli ﬁ er-douler chain which fabricated by IBM SiGe 0.13 µm BiCMOS technology shows 6.1 dB conversion gain and − 4.1 dBm saturation output power with 26.5 mA operating current and 2.8 V supply voltage, and the fundamental and 3rd harmonic rejection at 42 GHz are 17.5 dB and 38.6 dB, respectively.
Chemical Composition, Nitrogen Fractions and Amino Acids Profile of Milk from Different Animal Species

Milk composition is an imperative aspect which influences the quality of dairy products. The objective of study was to compare the chemical composition, nitrogen fractions and amino acids profile of milk from buffalo, cow, sheep, goat, and camel. Sheep milk was found to be highest in fat (6.82%±0.04%), solid-not-fat (11.24%±0.02%), total solids (18.05%±0.05%), protein (5.15%±0.06%) and casein (3.87%±0.04%) contents followed by buffalo milk. Maximum whey proteins were observed in camel milk (0.80%±0.03%), buffalo (0.68%±0.02%) and sheep (0.66%±0.02%) milk. The non-protein-nitrogen contents varied from 0.33% to 0.62% among different milk species. The highest r-values were recorded for correlations between crude protein and casein in buffalo (r = 0.82), cow (r = 0.88), sheep (r = 0.86) and goat milk (r = 0.98). The caseins and whey proteins were also positively correlated with true proteins in all milk species. A favorable balance of branched-chain amino acids; leucine, isoleucine, and valine were found both in casein and whey proteins. Leucine content was highest in cow (108±2.3 mg/g), camel (96±2.2 mg/g) and buffalo (90±2.4 mg/g) milk caseins. Maximum concentrations of isoleucine, phenylalanine, and histidine were noticed in goat milk caseins. Glutamic acid and proline were dominant among non-essential amino acids. Conclusively, current exploration is important for milk processors to design nutritious and consistent quality end products.
Reliability-Aware Power Management Of Multi-Core Systems (MPSoCs)

Long-term reliability of processors in embedded systems is experiencing growing attention since decreasing feature sizes and increasing power consumption have a negative inuence on the lifespan. Among other measures, the reliability can be inuenced signican tly by Dynamic Power Management (DPM), since it aects the processor’s temperature. Compared to single-core systems recongurable multi-core SoCs oer much more possibilities to optimize power and reliability. The impact of dieren t DPM-strategies on the lifespan of multi-core processors is the focus of this presentation. It is shown that the long-term reliability of a multi-core system can be inuenced deliberately with dieren t DPM strategies and that temperature cycling greatly inuences the estimated lifespan. In this presentation, a new reliability-aware dynamic power management (RADPM) policy is explained.
The capacity of quantum channel with general signal states

It is shown that the capacity of a classical-quantum channel with arbitrary (possibly mixed) states equals to the maximum of the entropy bound with respect to all apriori distributions. This completes the recent result of Hausladen, Jozsa, Schumacher, Westmoreland and Wooters, who proved the equality for the pure state channel.
Testimony and Epistemic Risk: The Dependence Account

In this paper, I give an answer to the central epistemic question regarding the normative requirements for beliefs based on testimony. My suggestion here is that our best strategy for coming up with the conditions for justification is to look at cases where the adoption of the belief matters to the person considering it. This leads me to develop, in Part One of the paper, an interest-relative theory of justification, according to which our justification for a proposition p depends on our evidence in favour of p in proportion to our interest in p, as signalled by the epistemic risk we take in believing that p is true. In Part Two, I argue that this theory shows that the reductivist view offers a better normative account for the epistemic status of beliefs based on testimony than the credulist one, but it is inaptly named; the view I develop here is better conceived of as The Dependence Account.
