Wall shear stress and atherosclerosis: numerical blood flow simulations in the mouse aortic arch (2007)

The aims of this study were (1) to demonstrate the feasibility of computational fluid dynamic (CFD) modelling of realistic blood flow in the mouse aortic arch, and (2) to determine the relation of wall shear stress and atherosclerosis in the mouse aortic arch. ApoE knockout mice were chosen for this study. The blood flow fraction in the major branches of the mouse aortic arch was measured by ultrasound biomicroscopy. The geometry of the aortic arch was captured by plastic casting and micro CT imaging. Mouse blood viscosities were measured by rheometry. A pathological examination was performed. A well-validated in-house finite element code, which solves the three dimensional Navier-Stokes equations, was used to compute the wall shear stress and velocity patterns in the ascending aorta and the aortic arch. The distribution of the wall shear stress was correlated with the distribution of the atherosclerosis from the pathological examination in order to investigate the effect of wall shear stress on atherosclerosis. It is concluded that CFD modeling of hemodynamics in the mouse aortic arch is feasible. Qualitative impressions show that atherosclerosis was related with the region of low wall shear stress in mouse aortic arch.
Prolonged Exposure of Mice to 340 kV/m Electrostatic Field (1981)

Male and female mice were continuously exposed to an extremely intense electrostatic field for approximately 5000 h before they were sacrificed for tests. The progenies resulting from breeding the various couples were also subjected to the same field. Data concerning various biological parameters such as water consumption, body weight, rate of growth, number of progenies, blood count and chemistry, proteins, and organ histology are analyzed and compared with the results obtained from the control animals.

The total layout area including dummy structures is 100μm × 85μm.
Optical, vibrational, thermal, electrical, damage, and phase-matching properties of lithium thioindate (2004)

Lithium thioindate (LiInS2) is a new nonlinear chalcogenide biaxial material transparent from 0.4 to 12 μm that has been successfully grown in large sizes and with good optical quality. We report on new physical properties that are relevant for laser and nonlinear optics applications. With respect to AgGaS(e)2 ternary chalcopyrite materials, LiInS2 displays a nearly isotropic thermal expansion behavior, a 5-times-larger thermal conductivity associated with high optical damage thresholds, and an extremely low-intensity-dependent absorption, allowing direct high-power downconversion from the near-IR to the deep mid-IR. Continuous-wave difference-frequency generation (5–11 μm) of Ti:sapphire laser sources is reported for the first time to our knowledge.
Concurrency control and recovery on lightweight directory access protocol (2003)

In this paper we provide a concurrency control and recovery (CCR) mechanism over cached LDAP objects. An LDAP server can be directly queried using system calls to retrieve data. Existing LDAP implementations do not provide CCR mechanisms. In such cases, it is up to the application to verify that accesses remain serialized. Our mechanism provides an independent layer over an existing LDAP server (Sun One Directory Server), which handles all user requests, serializes them based on 2 Phase Locking and Timestamp Ordering mechanisms and provides XML-based logging for recovery management. Furthermore, while current LDAP servers only provide object-level locking, our scheme serializes transactions on individual attributes of LDAP objects (attribute-level locking). We have developed a Directory Enabled Network (DEN) Simulator that operates on a subset of directory objects on an existing LDAP server to test the proposed mechanism. We perform experiments to show that our mechanism can gracefully address concurrency and recovery related issues over and LDAP server.
5‐fluorouracil metabolite patterns in viable and necrotic tumor areas of murine colon carcinoma determined by 19F NMR spectroscopy (1996)

High-resolution 19F NMR spectroscopy at 9.4 T was used to study the difference in the metabolite pattern of 5-fluorouracil (5-FU) between viable and necrotic tissues of C38 murine colon tumors grown in C57BI/6 mice. Studies were performed on perchloric acid extracts of these tumor fractions after 5-FU treatment. The 19F nuclear magnetic resonance spectra exhibited resonances representing 5-FU, the catabolites alpha-fluoro-beta-ureidopropionic acid and alpha-fluoro-beta-alanine, as well as several fluoronucleotide anabolites. The absolute concentrations of anabolites and catabolites and the anabolite-to-catabolite ratio were significantly lower in the necrotic fraction than in the viable tumor fraction 50 min after administration of 5-FU, whereas the absolute concentration of 5-FU was the same. Therefore, in 5-FU metabolism studies with NMR spectroscopy, it is important to consider the necrotic contribution to the tumor volume.
Evaluation of Airport Environmental Carrying Capacity: A Case Study in Guangzhou Baiyun International Airport, China (2021)

In order to clarify the comprehensive operational capabilities of the airport and better plan the sustainable development mode of the airport, this paper studies the evaluation method of airport environmental carrying capacity. First, this paper proposes the concept of airport environmental carrying capacity by taking into account the complex characteristics of airports affected by multiple factors and then selects 16 representative evaluation indicators to construct an indicator system based on the Driving Force-Pressure-State-Response (DPSR) framework. Finally, the accelerated genetic algorithm-projection pursuit model is established to model a comprehensive evaluation index, which is used to calculate the airport environmental carrying capacity (AECC). The results of the case study show that the AECC of Guangzhou Baiyun International Airport (CAN) decreased year by year from 2008 to 2017, which is in line with the coordinated development level of CAN. By analysing the changing mechanism of AECC and indicators, we get 6 key influencing indicators that led to the continuous decline of AECC and put forward some political suggestions to improve the AECC.
The Effect of Non-performing Loans on Performance and Profitability: A Comparative Analysis from Banking Sector of Bangladesh (2020)

The purpose of this paper is to assess the intensity of ‘Non-performing Loan’ and its adverse impact on the performance and profitability of the banking sector of Bangladesh. A comparative scenario of state-owned commercial banks and private commercial banks have also been presented in this study. The foregoing discussion of NPL from the perspective of Bangladesh reveals that the amount of defaulted loans have reached an alarming position which degrades the banking industry and makes the economy stagnant. The comparative analysis showed that SOCBs have a higher amount of total NPL, gross NPL ratio and net NPL ratio than that of PCBs. Share in industry total assets, share in deposit and also change in the contribution of industry assets of SOCBs are very lower in comparison to PCBs. Capital adequacy, capital to risk-weighted assets, ROA, ROE and maintained provision of SOCBs are very poor while PCBs have satisfactory performance. Active implementation of policies, proper and adequate surveillance of SOCBs, qualified and neutral board members and non-executives, improved lending process, enforcement of punishable measures and most importantly strong ethical attitude are some of the possible and effective recommendations that should be implemented to eradicate the root of NPL from this emerging economy.
Carotenogenesis during tuber development and storage in potato (2004)

Germplasm of Solanum tuberosum and Solanum phureja exhibit a wide (over 20-fold) variation in tuber carotenoid content. The levels of carotenoids during tuber development and storage were compared in a high carotenoid-accumulating S. phureja accession (DB375\1) with two S. tuberosum cultivars (Pentland Javelin and Desiree) that accumulate lower levels of tuber carotenoid. On a dry weight basis, total carotenoid levels were at a maximum early in tuber development. However, in the S. phureja accession, carotenoid levels remained at a high level throughout tuber development, whereas in the S. tuberosum accessions, carotenoid content decreased as dry weight increased. The carotenoid profiles of tissues during tuber development were analysed in greater detail by reverse phase HPLC. In S. phureja tubers at maturity the major carotenoids were zeaxanthin, antheraxanthin, and violaxanthin. Following 9 months storage at 4 degrees C the levels of zeaxanthin and antheraxanthin decreased, whereas the level of lutein increased; overall, however, there was only a small decrease in total carotenoid content. In order to explore the reasons for the wide variation in tuber carotenoid content, the expression patterns of the major genes encoding the enzymes of the carotenoid biosynthetic pathway were compared. Significant differences in the profiles were detected, suggesting that transcriptional control or mRNA stability gives rise to the large differences in tuber carotenoid content. In particular, there was an inverse trend between the level of zeaxanthin epoxidase transcript level and tuber carotenoid content in a range of potato germplasm, giving rise to an hypothesis for the regulation of carotenogenesis in potato tubers.
Review of precision irrigation technologies and their application (2010)

Precision irrigation is still in its infancy both in Australia and internationally. Despite the widespread promotion and adoption of precision agriculture in dry land cropping systems, the concept of precision irrigation or irrigation as a component of precision agricultural systems has not been widely canvassed nor its potential evaluated. This report is the outcome from a NPSI funded review of relevant irrigation research, existing technologies and the use of precision irrigation. It includes an assessment of the role of current irrigation application technologies in precision irrigation, as well as variable rate applications, adaptive control and the sensing and decision support requirements. The review also provides a framework to guide research and development of precision irrigation and its associated sensing, control, and decision support technologies.
Use of imperfectly segmented nuclei in the classification of histopathology images of breast cancer (2010)

Many features used in the analysis of pathology imagery are inspired by grading features defined by clinical pathologists as important for diagnosis and characterization. A large majority of these features are features of cell nuclei; as such, there is often the desire to segment the imagery into individual nuclei prior to feature extraction and further analysis. In this paper we present an analysis of the utility of imperfectly segmented cell nuclei for classification of H&E stained histopathology imagery of breast tissue. We show the object- and image-level classification performance using these imperfectly segmented nuclei in a benign versus malignant decision. Results indicate that very good classification accuracies can be achieved with imperfectly segmented nuclei and further that perfect nuclei segmentation does not necessarily guarantee better classification accuracy.
Evaluation of Technologies to Treat Oil Field Produced Water to Drinking Water or Reuse Quality (1997)

Abstract Treatment technologies for reclaiming oil field produced water for beneficial reuse were evaluated, including thermal and membrane processes for salinity removal. Warm precipitative softening and high-pH reverse osmosis were selected for pilot testing based on a literature review of treatment technologies and results from bench-scale softening tests that indicated hardness, boron and silica removal could be simultaneously optimized.
Factors affecting the shelf‐life of pasteurized double cream (1981)

The major cause of cream spoilage in the south of Scotland is post‐pasteurization contamination, which can be effectively reduced by the adoption of aseptic handling techniques.
Bacteriophage-Derived PeptidaseCHAPKEliminates and Prevents Staphylococcal Biofilms (2013)

New antibacterial agents are urgently needed for the elimination of biofilm-forming bacteria that are highly resistant to traditional antimicrobial agents. Proliferation of such bacteria can lead to significant economic losses in the agri-food sector. This study demonstrates the potential of the bacteriophage-derived peptidase, CHAP(K), as a biocidal agent for the rapid disruption of biofilm-forming staphylococci, commonly associated with bovine mastitis. Purified CHAP(K) applied to biofilms of Staphylococcus aureus DPC5246 completely eliminated the staphylococcal biofilms within 4 h. In addition, CHAP(K) was able to prevent biofilm formation by this strain. The CHAP(K) lysin also reduced S. aureus in a skin decolonization model. Our data demonstrates the potential of CHAP(K) as a biocidal agent for prevention and treatment of biofilm-associated staphylococcal infections or as a decontaminating agent in the food and healthcare sectors.
A hardware scheduler for complex real-time systems (2003)

The problem of jointly scheduling both hard deadline periodic tasks and soft aperiodic tasks has been the subject of considerable research in real-time systems. One of the most widely accepted solutions for this problem are slack stealing algorithms. However, these algorithms are rather impractical, since they all imply a considerable scheduler overhead. This paper faces the overhead problem by introducing a complete hardware architecture that implements slack stealing in hardware using an optimal algorithm that has been completely redesigned to perform efficiently in hardware. The proposed solution is a circuit that behaves as a kind of sophisticated interrupt controller that takes the task workload and the interrupts as inputs, and provides an output to inform the CPU which is the highest priority task. From the point of view of hardware design, the algorithm involves two main problems: first, to select the highest priority task at every moment and, second, to locate a set of slack gaps in a real-time computation. Locating slack gaps in a real-time computation is a problem that requires to "look forward in time" into the forecast schedule of a given workload. This paper presents a novel architecture that shows how to solve this problem in an efficient way using an event-driven simulation. A timing analysis of the proposed design is also presented.
<title>Fast image filters as an alternative to reconstruction kernels in computed tomography</title> (2001)

In Computed Tomography, axial resolution is determined by the slice collimation and the spiral algorithm, while in-plane resolution is determined by the reconstruction kernel. Both choices select a tradeoff between image resolution (sharpness) and pixel noise. We investigated an alternative approach using default settings for image reconstruction which provide narrow reconstructed slice-width and high in-plane resolution. If smoother images are desired, we filter the original (sharp) images, instead of performing a new reconstruction with a smoother kernel. A suitable filter function in the frequency domain is the ratio of smooth and original (sharp) kernel. Efficient implementation was achieved by a Fourier transform of this ratio to the spatial domain. Separating the 2D spatial filtering into two subsequent 1D filtering stages in x- and y-direction further reduces computational complexity. Using this approach, arbitrarily oriented multi-planar reformats (MPRs) can be treated in exactly the same way as axial images. Due to efficient implementation, interactive modification of the filter settings becomes possible, which completely replace the variety of different reconstruction kernels. We implemented a further promising application of the method to thorax imaging, where different regions of the thorax (lungs and mediastinum) are jointly presented in the same images using different filter settings and different windowing.

Thermal Reliability for LED Lighting Design (2012)

Light output and quality of light will degrade over the lifetime of an LED assembly. Several failure mechanisms will determine the mode, rate and extent of degradation. Temperature exposure and temperature induced mechanical stresses are major culprits behind performance degradation. We will explain the physical-chemical nature of these mechanisms. In addition we will address tools to assess and model the robustness of a thermal design. Finally, we will highlight various solutions that will mitigate thermal degradation.
Preliminary Test of a Real-Time, Interactive Silent Speech Interface Based on Electromagnetic Articulograph (2014)

A silent speech interface (SSI) maps articulatory movement data to speech output. Although still in experimental stages, silent speech interfaces hold significant potential for facilitating oral communication in persons after laryngectomy or with other severe voice impairments. Despite the recent efforts on silent speech recognition algorithm development using offline data analysis, online test of SSIs have rarely been conducted. In this paper, we present a preliminary, online test of a real-time, interactive SSI based on electromagnetic motion tracking. The SSI played back synthesized speech sounds in response to the user's tongue and lip movements. Three English talkers participated in this test, where they mouthed (silently articulated) phrases using the device to complete a phrase-reading task. Among the three participants, 96.67% to 100% of the mouthed phrases were correctly recognized and corresponding synthesized sounds were played after a short delay. Furthermore, one participant demonstrated the feasibility of using the SSI for a short conversation. The experimental results demonstrated the feasibility and potential of silent speech interfaces based on electromagnetic articulograph for future clinical applications.
Transcriptional Blockade Induces p53-dependent Apoptosis Associated with Translocation of p53 to Mitochondria (2005)

The tumor suppressor p53 functions as a transcriptional activator to induce cell cycle arrest and apoptosis in response to DNA damage. Although p53 was also shown to mediate apoptosis in a manner independent of its transactivation activity, the mechanism and conditions that trigger such cell death have remained largely unknown. We have now shown that inhibition of RNA polymerase II-mediated transcription by alpha-amanitin or RNA interference induced p53-dependent apoptosis. Inhibition of pol II-mediated transcription resulted in down-regulation of p21Cip1, which was caused by both transcriptional suppression and protein degradation, despite eliciting p53 accumulation, allowing the cells to progress into S phase and then to undergo apoptosis. This cell death did not require the transcription of p53 target genes and was preceded by translocation of the accumulated p53 to mitochondria. Our data thus suggested that blockade of pol II-mediated transcription induced p53 accumulation in mitochondria and was the critical factor for eliciting p53-dependent but transcription-independent apoptosis.

Current-Phase Relations in Superconducting Bridges (1970)

The current-phase relation ${I}_{s}(\ensuremath{\phi})$ for an Anderson-Dayem bridge is investigated making experimental use of the quantum interference between two such bridges. Near ${T}_{c}$ and for critical currents $\ensuremath{\lesssim}10$ \ensuremath{\mu}A, ${I}_{s}(\ensuremath{\phi})$ is found to be nearly sinusoidal.
Efficacy of duloxetine for multisite pain in patients with knee pain due to osteoarthritis: An exploratory post hoc analysis of a Japanese phase 3 randomized study (2020)

These results are consistent with duloxetine enhancing the activity of descending inhibitory pain pathways that are dysfunctional in patients with central sensitization and multisite pain. In addition, these results suggest that duloxetine may be an effective choice of analgesic for patients with knee osteoarthritis and multisite pain.
Feature Based Stereo Matching Using Two‐Step Expansion (2014)

This paper proposes a novel method for stereo matching which is based on image features to produce a dense disparity map through two different expansion phases. It can find denser point correspondences than those of the existing seed‐growing algorithms, and it has a good performance in short and wide baseline situations. This method supposes that all pixel coordinates in each image segment corresponding to a 3D surface separately satisfy projective geometry of 1D in horizontal axis. Firstly, a state‐of‐the‐art method of feature matching is used to obtain sparse support points and an image segmentation‐based prior is employed to assist the first region outspread. Secondly, the first‐step expansion is to find more feature correspondences in the uniform region via initial support points, which is based on the invariant cross ratio in 1D projective transformation. In order to find enough point correspondences, we use a regular seed‐growing algorithm as the second‐step expansion and produce a quasi‐dense disparity map. Finally, two different methods are used to obtain dense disparity map from quasi‐dense pixel correspondences. Experimental results show the effectiveness of our method.
