Abstract:
ABSTRACT Aeromonas salmonicida subsp. salmonicida, the etiological agent of furunculosis in fish, produces a catechol-type siderophore under iron-limiting conditions. In this study, the Fur titration assay (FURTA) was used to identify a cluster of six genes, asbG, asbF, asbD, asbC, asbB, and asbI, encoding proteins similar to components of the siderophore biosynthetic machinery in other bacteria. Reverse transcriptase PCR analyses showed that this cluster consists of four iron-regulated transcriptional units. Mutants with deletions in either asbD (encoding a multidomain nonribosomal peptide synthetase), asbG (encoding a histidine decarboxylase), or asbC (encoding a predicted histamine monooxygenase) did not grow under iron-limiting conditions and did not produce siderophores. Growth of the ΔasbG strain under iron starvation conditions was restored by addition of histamine, suggesting that the siderophore in this species could contain a histamine-derived moiety. None of the mutants could grow in the presence of transferrin, indicating that A. salmonicida uses the catechol-type siderophore for removal of iron from transferrin rather than relying on a receptor for this iron-binding protein. All 18 A. salmonicida strains analyzed by DNA probe hybridization were positive in tests for the presence of the asbD gene, and all of them promoted the growth of asbD, asbG, and asbC mutants, suggesting that this siderophore-mediated iron uptake system is conserved among A. salmonicida isolates. This study provides the first description of siderophore biosynthesis genes in this fish pathogen, and the results demonstrate that the asbD, asbG, and asbC genes are necessary for the production of a catecholate siderophore that is essential for the growth of A. salmonicida under iron limitation conditions.

Abstract:
e13096 Background: Safety analyses of targeted oncology therapies often require cancer stage and receptor status. Automated claims databases offer the largest populations to study rare outcomes, but lack these characteristics. We conducted a validation study of claims data using predictive models to identify two cohorts of women with early-stage and advanced-stage ER+/HER2- breast cancer (ESBC and ASBC, respectively). Methods: Retrospective cohort and validation study using electronic data linkage of a nationwide claims database (HealthCore Integrated Research Database – HIRD) and Anthem’s Cancer Care Quality program (CCQP). The CCQP served as a validation sample. We used claims data to develop two predictive models to estimate breast cancer stage and receptor status. We applied these models to the HIRD to identify ER+/HER2- ESBC and ASBC cohorts. In each cohort we assessed adverse event (AE) rates. Results:: In addition to breast cancer diagnoses, predictive models for ER+/HER2- ESBC and ASBC included 21 and 15 factors, respectively (Table).When compared to an a priori ASBC algorithm developed from clinical experience, the claims-based predictive model for ASBC had better PPV (0.78 v. 0.62) with similar sensitivity (0.39 v. 0.38). For the ASBC cohort, selected AE rates per 100 person-years included: anemia, 26.4; neutropenia, 14.3; pulmonary embolism, 5.7; and leukopenia, 4.0. Conclusions: Identification ofcancer stage and biomarkers using claims data can be improved through predictive modeling. ER+/HER2- ESBC and ASBC cohorts are being utilized for characterizing indications and conducting safety evaluations of targeted therapies. [Table: see text]

Abstract:
Abstract In this study, spent Auricularia auricula substrate (AS)-derived biochar (ASBCs) and activated biochar with NaOH (A-ASBC) were evaluated for the adsorption of cationic azo dyes, including methylene blue (MB), rhodamine B (RB), and crystal violet (CV), from single and binary adsorptive systems. A-ASBC showed a higher maximum adsorption capacity for these dyes (MB: 53.62 mg·g−1, RB: 32.33 mg·g−1, CV: 735.73 mg·g−1) than ASBCs in a single system because it had a greater specific surface area and more oxygen containing-functional groups on the surface. The adsorption process of the three dyes onto the adsorbents was in good agreement with the Freundlich adsorption isotherm and fit the pseudo-second-order kinetic model, which revealed sorbate polymolecular layer formation over the adsorbent surface and the involvement of chemisorption. The adsorption mechanism showed that the adsorption of three dyes on adsorbents could be postulated as a multistep process with extraordinary affinity-induced adsorption in terms of both physisorption and chemisorption. In the binary adsorptive system, the results showed that all MB, RB, and CV had antagonistic/competitive effects on each other's adsorption (QBinary/QSingle < 1). Furthermore, a phytotoxic assay affirmed the effectiveness of the adsorbent in adsorbing dye species from aqueous solutions using Brassica pekinensis L. seeds as the model. Therefore, activated biochar prepared from AS can be used as a potentially economical and effective adsorbent for treating printing and dyeing wastewater.

Abstract:
Nano-zero-valent iron biochar derived from almond shell (nZVI-ASBC) was used for hexavalent chromium (CR) removal. Experiments showed that pH was the main factor (p < 0.01) that affected the experimental results. At a dosage of 10 mg·L−1 and pH of 2–6, in the first 60 min, nZVI-ASBC exhibited a removal efficiency of 99.8%, which was approximately 20% higher than the removal yield at pH 7–11. Fourier transform infrared spectroscopy results indicated N-H was the main functional group that influenced the chemisorption process. The pseudo second-order dynamics and Langmuir isotherm models proved to be the most suitable. Thermodynamic studies showed that the reaction was exothermic and spontaneous at low temperatures (T < 317 K). Various interaction mechanisms, including adsorption and reduction, were adopted for the removal of Cr(VI) using the nZVI-ASBC composite. The findings showed that the BC-modified nZVI prepared with almond shell exerts a good effect and could be used for the removal of Cr(VI).

Abstract:
Abstract Abstract 1232 Acute myeloid leukemia (AML) is a hematological malignancy of the myeloid lineage characterized by an accumulation of abnormal immature white blood cells as a result of arrested myeloid differentiation. In the clinical setting, promyelocytic leukemic cells can be induced to differentiate into mature granulocytes by all-trans retinoic acid (ATRA), which acts by targeting oncogenic transcription factors. Expression profiling has previously identified ASB2, a member of the ankyrin repeat and SOCS box protein family as an ATRA target gene. ASBs negatively regulate cytokine signaling by mediating the ubiquitination of a broad range of target proteins. Furthermore, ASB proteins may regulate hematopoietic differentiation as suggested by ASB2 mediated degradation of the mixed lineage leukemia (MLL) protein and HOX gene down-regulation. MLL fusion proteins, present in approximately 10% of AML cases, have been found to be resistant to ASB2 mediated degradation which may contribute to leukemogenesis. Given that ASB2 plays a role in modulating differentiation and is ATRA induced it is feasible that other family members behave similarly. To understand the role of ASB proteins in hematopoietic differentiation we examined the expression profiles of ASB genes during normal myeloid differentiation using cells isolated at each stage of differentiation towards the granulocyte lineage. Alongside this, both ATRA-induced and DMSO-induced differentiation in AML cell lines (HL-60 and NB4) was assessed. In addition, ASB expression was analysed in the MILE study, which encompasses expression profiling of 16 leukemic subtypes, an independent cohort of clinically phenotyped patient samples, and normal bone marrow. Candidate ASBs who exhibited significantly different expression were identified by bioinformatic analysis of the MILE study and patient samples. One candidate (ASB3) was selected for silencing by shRNA and the resultant phenotype was assessed by proliferation ability, apoptosis potential and differentiation capacity. Furthermore, ASB3 silencing was analysed by Affymetrix microarrays to identify potential targets of ASB3. ASBs were found to be differentially expressed throughout normal hematopoietic differentiation with the highest expression in immature cells. In particular, ASB3 exhibited a two-fold decrease (p<0.001) in expression as myeloid cells matured. Several ASBs showed differential expression between AML patient samples and normal bone marrow with ASB3 exhibiting aberrant over-expression in AML (p≤0.005). Furthermore, Kaplan Meier plots using the MILE dataset indicated AML patients with FAB AML M0-M2 possess lower ASB3 expression which was associated with reduced overall survival and a poorer prognosis (p<0.05). ATRA or DMSO induced differentiation of HL-60 and NB4 cells altered ASB3 expression ten-fold (p<0.001) suggesting that the association of ASB3 with differentiation is not ATRA specific. Silencing of ASB3 expression (70% ±10%) in HL-60 and NB4 cells resulted in decreased proliferation and a 17% ±6% increase in apoptosis (p<0.01). In addition, reduced ASB3 expression markedly inhibited ATRA-induced differentiation of HL-60 and NB4 cells and ASB3 expression levels remained at a low level. Microarray analysis identified 78 differentially expressed genes between control and ASB3 silencing (p<0.05) including key genes specifically involved in apoptosis and hematopoietic differentiation e.g. PBX1, RUNX2 and CD44 were up-regulated during ASB3 silencing while ZNRF1, HOXA7 and CSRP2 were down-regulated when ASB3 was silenced. As ASB3 is highly expressed in myeloid progenitors and loss of expression blocks ATRA-induced differentiation it is possible ASB3 may play a role in myeloid differentiation. Little is known about the function of ASB3 although it has been suggested that it is a negative regulator of tumor necrosis factor receptor II (TNF-R2). Our study, and others, would suggest that it may have a role in the regulation of transcription factors important for differentiation e.g. HOX genes, as with ASB2. Furthermore, poor prognosis AML exhibited lower ASB3 expression predominantly in the most immature AML subtypes which suggests that without ASB3 the AML cells are unable to differentiate. Additional studies are required to develop our understanding of the function of ASB3 in myeloid differentiation and its contribution to leukemogenesis.

Abstract:
The article deals with the interpolation of the Balling alcohol factors, given at isolated points in 1% (m/m) increments ranging from 1 to 30% in the Hrach table published in 1927. Interpolation was necessery for the calculation of real (RDF) or apparent (ADF) degree of attenuation, according to which optimal barley varieties were selected for beer production. Analytica EBC initially preferred ADF, although it also reported RDF, used by ASBC. According to ASBC, the Balling RDF is multiplied by a correction factor or calculated using a modified calculation formula. Both ways gave the same results and increased Balling RDF values by 1-2% m/m. Refractometry with a pocket digital refractometer set to °Bx allows beer analysis from a minimum sample volume.

Abstract:
Much remains to be discovered about the intersection of tissue-specific transcription control and the epigenetics of skeletal muscle (SkM), a very complex and dynamic organ. From four gene families, Leucine-Rich Repeat Containing (LRRC), Oxysterol Binding Protein Like (OSBPL), Ankyrin Repeat and Socs Box (ASB), and Transmembrane Protein (TMEM), we chose 21 genes that are preferentially expressed in human SkM relative to 52 other tissue types and analyzed relationships between their tissue-specific epigenetics and expression. We also compared their genetics, proteomics, and descriptions in the literature. For this study, we identified genes with little or no previous descriptions of SkM functionality (ASB4, ASB8, ASB10, ASB12, ASB16, LRRC14B, LRRC20, LRRC30, TMEM52, TMEM233, OSBPL6/ORP6, and OSBPL11/ORP11) and included genes whose SkM functions had been previously addressed (ASB2, ASB5, ASB11, ASB15, LRRC2, LRRC38, LRRC39, TMEM38A/TRIC-A, and TMEM38B/TRIC-B). Some of these genes have associations with SkM or heart disease, cancer, bone disease, or other diseases. Among the transcription-related SkM epigenetic features that we identified were: super-enhancers, promoter DNA hypomethylation, lengthening of constitutive low-methylated promoter regions, and SkM-related enhancers for one gene embedded in a neighboring gene (e.g., ASB8-PFKM, LRRC39-DBT, and LRRC14B-PLEKHG4B gene-pairs). In addition, highly or lowly co-expressed long non-coding RNA (lncRNA) genes probably regulate several of these genes. Our findings give insights into tissue-specific epigenetic patterns and functionality of related genes in a gene family and can elucidate normal and disease-related regulation of gene expression in SkM.

Abstract:
Este trabalho teve como propósito avaliar um aquecedor solar de baixo custo para que pudesse servir como método alternativo na obtenção de água quente nas torneiras e chuveiros das residências e ainda reduzir custos com energia elétrica. Diferente do aquecedor convencional de cobre e vidro, o aquecedor solar de baixo custo tem seu sistema basicamente inteiro de PVC o que o torna financeiramente mais viável e sua instalação muito mais econômica, chegando a ser até 5 vezes mais barata. Contudo, durante 1 (um) ano observou-se o comportamento deste e de vários coletores quanto à eficiência de absorção solar e geração de água quente para a Região Noroeste do Estado de São Paulo. De iní­cio, com base em estudos anteriores, foi desenvolvido um protótipo e coletada diversas medidas da temperatura da água. Assim pode-se deduzir um máximo rendimento para o material, PVC, já que em elevada temperatura poderia levá-lo a uma possí­vel deformação, e, até não aquecer a água na temperatura adequada caso houvesse pouca absorção de radiação solar. Os dados coletados serviram para dimensionar o sistema coletor/reservatório, e assim foram coletados valores de inclinação, temperatura e armazenamento de água aproximados do rendimento máximo. Após os dimensionamentos e a coleta de novos dados, constatou-se um ótimo rendimento do sistema, que alcançou ganho médio de 14°C, com coletor operando com inclinação de 30°, concluindo sua viabilidade na região devido à alta incidência de radiação solar.

Abstract:
Thin metal sheets have for long been the dominant structural components in automotive bodies, but as environmental concerns mount new materials are needed to reduce mass. Advanced Sheet Moulding Compounds (ASMC) is a carbon fibre composite with short fibres and has been put forward as an alternative. It is both light and has good durability and can be formed in a mould similarly to steel sheets. A distinct advantage is that unlike for steel sheets the thickness in an ASMC component can be varied and stiffeners integrated. This creates great opportunities for optimisation, but as know-how in the industry is scarce a methodology is necessary. This master’s thesis describes a method developed for optimising structural components manufactured in ASMC by analysing a backplate mounted in a Body-In-White (BIW). The optimisation design process was first developed in a simplified model made to mimic a BIW without all the complexities therein. In this thesis free-size optimisation was done individually and coupled with adding uni-directional (UD) fibres and ribs to the backplate. This process was then verified in an accurate car body model and the process translated rather well to a more realistic model as favourable results were obtained. Optimisation resulted in more than 50% decrease in the component’s mass and body torsional stiffness could be increased by up to 7%. A step-by-step guide for this process is presented. Moving forward the design methodology needs to be verified and developed further for different structures and load cases. It is believed that the process detailed works well for many different structures as is, but improvements can be made and are ultimately necessary.
Under lång tid har pressad metallplåt varit det dominerande strukturella materialet i bilkarosser, men i takt med att miljövänliga lösningar blir mer och mer viktiga så behövs nya material för att reducera vikt. Advanced Sheet Moulding Compounds (ASMC) är en kolfiber komposit med korta fibrer och har lagts fram som ett alternativ. Materialet är både lätt och har goda hållfasthetsegenskaper och kan formas i en gjutform i en process som liknar pressning av plåt. En stor fördel är att till skillnad från metallplåt så kan tjockleken i en ASMC komponent varieras och förstyvningar kan integreras. Detta skapar stora möjligheter för optimering, men då erfarenhet av dessa material i industrin är liten behövs metoder för detta. I detta examensarbete beskrivs en metod som utvecklats för optimering av ASMC komponenter via analys av en vridplåt monterad i en bil. För att undvika onödig komplexitet utvecklades optimeringsprocessen först i en förenklad modell som skulle härma en Body-In-White (BIW). Free-size optimering användes individuellt och tillsammans med att lägga in enkelriktade fibrer och förstyvningar. Processen verifierades sedan i en noggrann karossmodell, och den fungerade väl då gynnsamma resultat erhölls. Det visades att optimering av ryggplåten kan kraftigt reducera dess vikt och öka vridstyvheten i ett fordon. Optimering resulterade i mer än 50% minskning av komponents vikt och bilkroppens vridstyvhet kunde höjas med upp till 7%. En guide för processen som förklarar steg för steg hur optimering av ASMC ska utföras har presenterats. I framtiden bör metoden verifieras och utvecklas ytterligare för andra strukturer och last fall. Det förmodas att den beskrivna processen fungerar som den är, men förbättringar kan göras och behövs.

The architecture of the High Rate (600 Mega-bits per second) Digital Demodulator (HRDD) ASIC capable of demodulating BPSK and QPSK modulated data is presented in this paper. The advantages of all-digital processing include increased flexibility and reliability with reduced reproduction costs. Conventional serial digital processing would require high processing rates necessitating a hardware implementation other than CMOS technology such as Gallium Arsenide (GaAs) which has high cost and power requirements. It is more desirable to use CMOS technology with its lower power requirements and higher gate density. However, digital demodulation of high data rates in CMOS requires parallel algorithms to process the sampled data at a rate lower than the data rate. The parallel processing algorithms described here were developed jointly by NASA’s Goddard Space Flight Center (GSFC) and the Jet Propulsion Laboratory (JPL). The resulting all-digital receiver has the capability to demodulate BPSK, QPSK, OQPSK, and DQPSK at data rates in excess of 300 Mega-bits per second (Mbps) per channel. This paper will provide an overview of the parallel architecture and features of the HRDR ASIC. In addition, this paper will provide an overview of the implementation of the hardware architectures used to create flexibility over conventional high rate analog or hybrid receivers. This flexibility includes a wide range of data rates, modulation schemes, and operating environments. In conclusion it will be shown how this high rate digital demodulator can be used with an off-the-shelf A/D and a flexible analog front end, both of which are numerically computer controlled, to produce a very flexible, low cost high rate digital receiver.

Abstract:

HMS Industrial Networks AB is in need of changing a communications solution that iscurrently based on an ASIC. This will be achieved by moving the communications solution toa FPGA with the help of the programming language VHDL. By doing this, it is possible toreduce the need for specific circuits, get a more flexible platform and thus get a cheapersolution.

This report describes a solution for how to move a network protocol from an ASIC to anFPGA. The report shows that the network slave device is working under the guidelines forthis project. This means that it is quite realistic to implement a fieldbus protocol on an FPGA,using VHDL and to maintain the same functionality as the earlier communications solution.

Abstract:
The ability of application specific integrated circuits (ASICs) to minimise the size and power consumption of electronic circuitry, makes their application to the design of ambulatory monitoring equipment, an attractive option. To this end, a multi-purpose mixed analogue and digital ASIC has been fabricated and incorporated into both a long-term recorder of adult heart rate (HR) and a recorder of electrophysiological signals. The adult HR recorder has been employed in a study of long-term daily HR patterns, which verified the ambulatory nature of this instrument, as well as its suitability for investigating HR variability. The electrophysiological signal recorder uses the ASIC to amplify, filter and digitise signals, which are then stored directly into static RAM. The analogue front-end of this instrument is flexible in terms of gain, bandwidth and sampling frequency allowing it be applied to a whole range of signals. This instrument has been used to record the antepartum fetal HR, as part of the development of an ambulatory, ASIC based recorder of fetal HR (FHR). These recordings have shown that a usable signal can be obtained from a mother in her home environment, whilst in various postures. The electrophysiological signal recorder has also been used to record the electrohysterogram (EHG), which is the name given to the electrical activity of the uterus, from abdominal electrodes during labour. A strong correlation was found to exist between tocographs derived from the EHG and tocographs produced by conventional means.

Abstract:
The Viterbi Algorithm is a popular method for decoding convolutional codes, receiving signals in the presence of intersymbol-interference, and channel equalization. In 1981 the European Telecommunications Administration (CEPT) created the Groupe Special Mobile (GSM) Committee to devise a unified pan-European digital mobile telephone standard. The proposed GSM receiver structure brings together Viterbi decoding and equilization. This thesis presents three VLSI designs of the Viterbi Algorithm with specific attention paid to the use of such modules within a GSM receiver. The first design uses a technique known as redundant number systems to produce a high speed decoder. The second design uses complementary pass-transistor logic to produce a low-power channel equalizer. The third design is a low area serial equalizer. In describing the three designs, redundant number systems and complementary pass-transistor logic are examined. It is shown that while redundant number systems can offer significant speed advantages over twos complement binary, there are other representations that can perform equally well, if not better. It will also be shown that complementary pass-transistor logic can offer a small improvement for VLSI circuits in terms of power consumption.

Abstract:
PLDs are commonplace in today's electronic products. When such devices reach their end-of-life, the product manufacturer must find a viable solution, both technical and economical. Replacing a PLD by an ASIC is a viable alternative that is explored in this paper, using a real case as an example. Boundary business conditions for deciding for this option are presented. Depending on these conditions, obsolescence can be seen as an opportunity for the improvement of the product, taking advantage of other benefits that an ASIC brings. As an ASIC development can be seen as risky, pricy, and as having a long time to market, a structured ASIC platform, called ICX, that mitigates all of these three aspects, is also presented.

Abstract:
<p>The West Kowloon Cultural District Artist Square Bridge (ASB) is a part of Hong Kong’s new art and cultural district development. It forms a primary pedestrian link between the adjacent MTR station and the new development. ASB is a design-and-build project consisting of a 78m clear spanning, 8m wide footbridge, an access lift tower and a 30m long staircase and escalators. The footbridge is a covered, dual steel arch and Vierendeel truss footbridge, that crosses an existing flyover, connecting the station shopping mall to the new development. During construction of ASB, very limited space was available on the new development site to accommodate the construction of ASB. These posed engineering challenges to the design and construction team. This paper presents the design of the ASB structures with particular focus on the main footbridge, and the challenges encountered during the design and construction of ASB and how incremental launching solution was developed to tackle these challenges.</p>

Full text
Abstract:
It is known that the Tresca yield theory predicts a lower bound of burst pressure, whereas the von Mises yield theory provides an upper bound of burst pressure of pipelines. To accurately predict the burst pressure, the present authors [1] recently developed a new multiaxial yield theory for isotropic hardening materials, based on an average shear stress criterion (ASSC). Extensive classic experiments showed that the ASSC criterion can well correlate the stress-strain relations for both initial yield and subsequent yield states. Based on the ASSC yield theory, a new theoretical solution of the burst pressure of pipelines at plastic collapse is developed as a function of pipe geometry, material hardening exponent, and ultimate tensile strength. This solution is then validated by experimental data for various pipeline steels. The ASSC yield theory is further applied to accurately determine actual burst pressure using available finite element software like ABAQUS, which currently adopts the von Mises yield criterion and the associate flow rule for isotropic elastic-plastic analysis. Four burst failure criteria: the Mises equivalent stress criterion, the maximum principal stress criterion, the Mises equivalent strain criterion and the maximum tensile strain criterion are developed as functions of the ultimate tensile stress and the strain hardening exponent. Application demonstrates that the proposed failure criteria in conjunction with ABAQUS numerical analysis can accurately determine burst pressure of pipelines.

Full text
Abstract:
Abstract Since the solid fuels like coal produce a lot of ash upon burning, the products of combustion can’t be expanded as it is in a Gas Turbine (GT). Hence, the operation of a combined cycle with solid fuels includes: (i) production of syngas from the coal to operate a gas turbine engine and (ii) using the leftover coal after gasification to produce steam and operate a steam turbine engine. To avoid the coal-gasification and to use the solid coal fuel as it is in a combined cycle power plant, a novel Air-Steam Combined Cycle (ASCC) is proposed in the present work. ASCC comprises a gas turbine cycle (operating by the Brayton cycle) with the air as the working fluid and a steam turbine cycle (operating by the Rankine cycle) with the steam as the working fluid. A fraction F of the air is compressed, regenerated and finally heated to an Air Turbine Inlet Temperature (ATIT) by the hot products of combustion produced upon burning of the bituminous coal in a combustor. The residual heat energy of products of combustion is then utilized in a Heat Recovery Steam Generator (HRSG) to generate the steam initially and subsequently to preheat the remaining fraction (1-F) of the air. After expansion in an air turbine, the hot air passes through a regenerator directly into a combustor along with the preheated air for burning the coal so as to utilize the energy of expanded air completely. ASCC is analyzed based on the first and second laws of thermodynamics and a computer code is developed in MATLAB to simulate the cycle performance at different compressor pressure ratios, ATITs, and HRSG pressures. The performance of ASCC is compared with that of Baseline Steam Turbine Cycle (BSTC) for the same flue gas (stack) temperature. It is found that the overall thermal efficiency of ASCC can go up to 33.0%–37.5% depending on the compressor pressure ratio, ATIT and HRSG pressure as against to 29.0%–29.5% of BSTC.

Abstract:
In this work, a new air hybrid engine configuration is introduced in which two throttles are used to manage the engine load in three modes of operation i.e. braking, air motor, and conventional mode. A Mean Value Model (MVM) of the engine is developed at braking mode and a new Adaptive Sliding Mode Controller (ASMC), recently proposed in the literature, is applied to control the engine torque at this mode. The results show that the controller performs remarkably well in terms of the robustness, tracking error convergence and disturbance attenuation. Chattering effect is also removed by utilizing the ASMC scheme.
