Detection of acoustic emission signals from partial discharge sources in oil-pressboard insulation system (2010)

Partial Discharges are major source of insulation failure in power transformers. Therefore, partial discharge (PD) measurement has been commonly carried out to detect and monitor PD activity in insulation in order to avoid from any catastrophic failure. In this research work, acoustic emission (AE) detection system is used to detect PD in an experimental tank filled with transformer oil. Three different types of PD sources to generate PD in the experimental tank are created from pressboards which are the plain pressboard, the floating metal in the pressboard and the bubble in pressboard. The AE signals due to the occurrence of PD from these sources are captured and recorded. Due to the large number of AE signals to be recorded by the Data Acquisition System, some of these signals may not be stored correctly in the system. Some of these signals may also be affected by the reflection and refraction phenomena, interference and attenuation of the AE signals. Hence, the preprocessing and validation of the acquired AE signals from the experimental setup are also explored in this paper. Finally, the valid AE signals due to three different types of PD sources are identified for further analysis.
Polyphenol Extracts from Hibiscus sabdariffa Linnaeus Attenuate Nephropathy in Experimental Type 1 Diabetes (2009)

Diabetic nephropathy progressed to end-stage renal disease (ESRD) is found in type 1 or type 2 diabetes. Oxidative stress is one of the precipitation factors in diabetic nephropathy. Previously, Hibiscus sabdariffa Linnaeus and its polyphenol extracts were found to possess antioxidative effects. This study is aimed to investigate the effect of Hibiscus sabdariffa L. polyphenol extract (HPE) in streptozotocin (STZ) induced diabetic nephropathy. The results show that HPE reduced kidney mass induced by STZ significantly, as well as improving hydropic change of renal proximal convoluted tubules in the rats. HPE also significantly reduced serum triglyceride, total cholesterol and LDL in STZ induced rats. Treatment with HPE significantly increased the activity of catalase and glutathione and reduced lipid peroxidation (thiobarbituric acid-reactive substances, TBARS). The findings of this research show the beneficial effects of HPE on STZ induced diabetic nephropathy including pathology, serum lipid profile and oxidative marker in kidney.
The ACE1 Electrical Impedance Tomography System for Thoracic Imaging (2018)

The design and performance of the ACE1 (Active Complex Electrode) electrical impedance tomography system for single-ended phasic voltage measurements is presented. The design of the hardware and calibration procedures allow for reconstruction of conductivity and permittivity images. Phase measurement is achieved with the ACE1 active electrode circuit which measures the amplitude and phase of the voltage and the applied current at the location at which current is injected into the body. An evaluation of the system performance under typical operating conditions includes details of demodulation and calibration and an in-depth look at insightful metrics, such as signal-to-noise ratio variations during a single current pattern. Static and dynamic images of conductivity and permittivity are presented from ACE1 data collected on tank phantoms and human subjects to illustrate the system's utility.

Topology control adopting optimal topology over update interval in mobile ad hoc networks (2019)

A topology control method for mobile ad hoc networks is proposed, in which the optimal topology of each topology update interval is adopted by considering both the dynamic positions of one-hop neighboring nodes and cumulative energy consumption to send data over the update interval. This approach of adopting the topology optimized over the update interval differs from an existing approach in which the topology update frequency is increased. Through performance simulation, conditions under which the proposed method is applicable are revealed by comparing the energy consumption of the proposed method to that of the existing method. Additionally, the proposed method is practical because it takes only several tens of milliseconds to determine the optimal topology even when using a CPU widely used for embedded devices.

Overcoming Immunosuppression and Pro-Tumor Inflammation in Lung Cancer with Combined IL-1β and PD-1 Inhibition (2022)

Inflammation in the tumor microenvironment is a complicit and known carcinogenesis driver. Inhibition of IL-1β, one of the most abundant and influential cytokines in the tumor microenvironment, may enhance the efficacy of PD-1. In a <i>post-hoc</i> analysis of phase III cardiovascular CANTOS trial, canakinumab, a monoclonal anti-IL-1β antibody, significantly reduced lung cancer incidence. Immune checkpoint inhibition (ICI) is the standard of care in non-small-cell lung cancer. However, ICI efficacy is heavily impacted by programmed death ligand-1 (PD-L1) status. Most patients with non-small-cell lung cancer have low PD-L1 expression levels. Thus, combinational strategies are needed to improve ICI efficacy and expand its use. Here, we describe the preclinical and clinical evidence to support the combination of IL-1β and PD-1 under investigation in the CANOPY program. The perioperative use of canakinumab with or without PD-1 inhibition in the CANOPY-N trial is described as a potential chemotherapy-free immunotherapy strategy.
Theoretical Investigation of Under-film Corrosion on Zn, Zn-Fe Alloy Coated Steel Sheets (1991)

For the purpose of the theoretical explanation on Cl- penetration behavior of Zn and Zn-Fe alloy coating investigated phenomenologically, the modeling of coating corrosion at under-film corrosion tip has been attempted and the balance of corrosion current by way of two micro circuits was formulated.The coating corrosion distance (Cl- penetration distance) and the effective length of the iron substrate contributing the formation of corrosion circuit between coating and iron substrate, the distribution ratio of corrosion current by way of circuit on coating to total coating corrosion current were required quantitatively.As a result, it made clear that the physical shap of coating corrosion circuit was defferent between atmospheric exposure and salt spray environments.
The Assessment of Cognitive and Physical Well-Being Through Ambient Sensor Measures of Movement Towards Longitudinal Monitoring of Activities of Daily Living (2021)

Ubiquitous sensing technologies are a well recognized concept these days. An individual with a rudimentary understanding of technology intuitively understands that their cell phone can track their whereabouts, detect their activity and communicate with their home devices. With the increased capability of technology, measurements have become finer and communication between devices has become faster and more efficient [1]. With such sensitive, co-operative systems it seems natural to extend this technology to measures of health and particularly measures of health at home and in other enclosed environments. This paper examines the role of sensor systems in the assessment of cognitive and physical well-being by first establishing the connections between well-being, cognition and mobility before discussing the sensors used to measure these concepts.

Modal Study of Refractive Effects on X-ray Laser Coherence (1991)

Current X-ray laser designs rely on amplifying spontaneous emission in a high temperature plasma. 1 An important issue involved in the study of X-ray lasers is the degree of transverse spatial coherence necessary for holographic applications. 2 Longitudinal coherence appears to be satisfactory, but transverse coherence remains problematic and requires further optimization study.
Sex moderates the effects of positive and negative affect on clinical pain in patients with knee osteoarthritis (2017)

The current study provides novel data that suggesting that the association of positive affect, negative affect, and pain are different in men versus women with KOA. Further understanding of the difference in affective expression between men and women may lead to the development of novel therapeutic interventions and help to identify additional modifiable factors in the prevention and management of pain.
PET Filaments with Radially-Differentiated Structure (1979)

An undrawn polyester monofilament was subjected to sequential solvent and thermal/stress crystallization during drawing to produce a radially-differentiated structure. Solvent-induced crystallization of outer regions of the filament was achieved using methylene chloride or dimethylformamide at room temperature. The thermal/stress crystallization of the filament core was conducted at a draw ratio of 4.0 at temperatures ranging from 90 to 120°C. The resulting filaments were characterized by measurements of density and mechanical properties, by wide-angle x-ray diffractometry, and by scanning electron microscopy. The structure of the outer regions of these novel filaments consists of highly- deformed spherulites, while the inner core is fibrillar in character with well-developed orientation and crystallinity. The extreme outer surface appears to be cavitated, leading to extremely high surface areas. It is proposed that such radially- differentiated filaments will have the combined desirable properties of spherulitic and fibrillar morphologies, such as high liquid-retention values, improved adhesion, and high strength.
Inhibition of the mevalonate pathway enhances cancer cell oncolysis mediated by M1 virus (2018)

Oncolytic virus is an attractive anticancer agent that selectively lyses cancer through targeting cancer cells rather than normal cells. Although M1 virus is effective against several cancer types, certain cancer cells present low sensitivity to it. Here we identified that most of the components in the cholesterol biosynthesis pathway are downregulated after M1 virus infection. Further functional studies illustrate that mevalonate/protein farnesylation/ras homolog family member Q (RHOQ) axis inhibits M1 virus replication. Further transcriptome analysis shows that RHOQ knockdown obviously suppresses Rab GTPase and ATP-mediated membrane transporter system, which may mediate the antiviral effect of RHOQ. Based on this, inhibition of the above pathway significantly enhances the anticancer potency of M1 virus in vitro, in vivo, and ex vivo. Our research provides an intriguing strategy for the rational combination of M1 virus with farnesyl transferase inhibitors to enhance therapeutic efficacy.
Hybrid Machine Learning Method to Determine the Optimal Operating Process Window in Aerosol Jet 3D Printing (2019)

Aerosol jet printing (AJP) is a three-dimensional (3D) noncontact and direct printing technology for fabricating customized microelectronic devices on flexible substrates. Despite the capability of fine feature deposition, the complicated relationship between the main process parameters will affect the printing quality significantly in a design space. In this paper, a novel hybrid machine learning method is proposed to determine the optimal operating process window for the AJP process in various design spaces. The proposed method consists of classic machine learning methods, including experimental sampling, data clustering, classification, and knowledge transfer. In the proposed method, a two-dimensional design space is fully explored by a Latin hypercube sampling experimental design at a certain print speed. Then, the influence of the sheath gas flow rate (SHGFR) and the carrier gas flow rate (CGFR) on the printed line quality is analyzed by a K-means clustering approach, and an optimal operating process window is determined by a support vector machine. To efficiently identify more operating process windows at different print speeds, a transfer learning approach is applied to exploit relatedness between different operating process windows. Hence, at a new print speed, the number of line samples for identifying a new operating process window is greatly reduced. Finally, to balance the complex relationship among SHGFR, CGFR, and print speed, a 3D operating process window is determined by an incremental classification approach. Different from experiment-based approaches adopted in 3D printing technologies for quality optimization, the proposed method is developed based on the theory of knowledge discovery and data mining. Therefore, the knowledge in different design spaces can be fully explored and transferred for printed line quality optimization. Moreover, the data-driven-based characteristics can help the proposed method develop a guideline for quality optimization in other 3D printing technologies.

Arctic Offshore Engineering—An Overview (1983)

The paper examines the state of the art of offshore drilling operations in the ice-infested Beaufort Sea region of the Canadian Arctic. As exploration and drilling proceed farther and farther from the shoreline into deeper and more hostile waters, new concepts are evolving in Arctic engineering technology to permit the economical recovery of vast resources of oil and gas over an extended season. Several of these innovations, including a deep-hulled drillship designed to protect the marine riser and reduce ice forces, artificial islands of the caisson type, and the use of massive icebreaking dredges, are described and illustrated.
Implementation and Performance Evaluation of the QUIC Protocol in Linux Kernel (2018)

QUIC is a new transport layer protocol proposed by Google that is rapidly increasing its share from Internet traffic. It is designed to improve performance for HTTPS connections and partly replace TCP, the dominant standard of Internet for decades, in application scenarios where new requirements such as packet encryption, stream multiplexing and connection migration are emerging and which have proven to be challenging for the TCP service model. QUIC has been massively deployed to serve some of the most popular Internet services, including YouTube. To enable easy deployment and rapid evolution to the protocol, the current deployment of QUIC runs in user-space, usually as part of the Chrome/Chromium browser. This potentially reduces the achievable performance of the protocol, as each message, including control messages, triggers a context switch between kernel and user spaces. To investigate the potential performance of QUIC in kernel mode and to achieve a fair comparison between QUIC and TCP, we implement QUIC in the Linux kernel where TCP and other transport layer protocols are running. We have conducted extensive measurements in both virtual machines and in a custom-built WIFI testbed to compare the two protocols. The empirical results indicate that QUIC outperforms TCP in major application scenarios such as network with low latency and high packet loss rate, while QUIC also shows a TCP-friendly rate control when the two protocols are running concurrently.
Shallow water equations with a complete Coriolis force and topography (2005)

This paper derives a set of two-dimensional equations describing a thin inviscid fluid layer flowing over topography in a frame rotating about an arbitrary axis. These equations retain various terms involving the locally horizontal components of the angular velocity vector that are discarded in the usual shallow water equations. The obliquely rotating shallow water equations are derived both by averaging the three-dimensional equations and from an averaged Lagrangian describing columnar motion using Hamilton’s principle. They share the same conservation properties as the usual shallow water equations, for the same energy and modified forms of the momentum and potential vorticity. They may also be expressed in noncanonical Hamiltonian form using the usual shallow water Hamiltonian and Poisson bracket. The conserved potential vorticity takes the standard shallow water form, but with the vertical component of the rotation vector replaced by the component locally normal to the surface midway between the upper and lower boundaries.
Detection of internally deposited actinides. Part II. Statistical techniques and risk analysis (1975)

Since a considerable number of workers at Oak Ridge National Laboratory work with compounds of the transuranic elements, computer techniques have been developed to evaluate phoswich spectra in order to determine lung burdens following accidental inhalation of $sup 239$Pu, $sup 241$Am, $sup 244$Cm or other isotopes. Two unfolding methods which have been found useful in the analysis of such cases are presented and discussed. These techniques have been used successfully to detect low levels of $sup 239$Pu, $sup 241$Am, $sup 244$Cm, $sup 233$U, $sup 90$Sr, and $sup 153$Gd in contaminated workers; but because of the current importance of $sup 239$Pu, emphasis is placed on detection of that isotope in the presence of $sup 241$Am and natural human background. In the health physics tradition of emphasizing benefit vs. risk, we also analyze uncertainties inherent in external counting of the actinides from the viewpoint of statistical risk analysis and derive decision criteria which are useful in determining whether various radioactive species have, in fact, been detected. These criteria are somewhat different from those encountered using traditional counting statistics and derive from the realization that some errors will always be made in scanning large numbers of radiation workers. The optimum decision strategy for the determination of lung burden is, therefore, one which minimizes the long-term risk of error. The usefulness of this approach to whole body counting will be discussed and analyzed. (auth)

Production of Fructose and Ethanol from Sugar Beet Molasses Using Saccharomyces cerevisiae ATCC 36858 (2002)

The production of enriched fructose syrups and ethanol from beet molasses using Saccharomyces cerevisiae ATCC 36858 was studied. In batch experiments with a total sugar concentration between 94.9 and 312.4 g/L, the fructose yield was above 93% of the theoretical value. The ethanol yield and volumetric productivity in the beet molasses media with sugar concentration below 276.2 g/L were in the range of 59-76% of theoretical value and between 0.48 and 2.97 g of ethanol/(L x h), respectively. The fructose fraction in the carbohydrates content of the produced syrups was more than 95% when the total initial sugar concentration in the medium was below 242.0 g/L. Some oligosaccharides and glycerol were also produced in all tested media. Raffinose and the produced oligosaccharides were completely consumed by the end of the fermentation process when the total initial sugar concentration was below 190.1 g/L. The glycerol concentration was below 16.1 g/L. The results could be useful for a potential industrial production of ethanol and high-fructose syrup from sugar beet molasses.
Physical structure and properties of 3‐methylbutene‐1 polymer and fiber (1970)

Abstract Isotactic 3‐methylbutene homopolymers and copolymers (of low 1‐olefin content) exhibit a major transition between 50 and 100°C, which dilatometric, density, and NMR observations indicate is not a glass transition, but rather a crystal–crystal transition occurring within the crystalline phase, the only phase present in significant amount. Fibers prepared from these polymers show a very high degree of orientation and crystallinity, have measured densities close to the theoretical crystal densities, and exhibit abrasion debris and electron microscopic evidence of crystalline lamellae. The fibers have a quasistatic initial modulus equivalent to the sonic modulus and exhibit very low stress relaxation and very high elastic recovery from large extensions. The fact that the fiber is highly crystalline and fully oriented, with a comparatively low initial modulus, high elastic recovery, and an extensibility of about 40%, indicate that the crystalline lamellae themselves, joined together in stacks, are able to deform (probably bend) elastically, and that the aggregate is able to undergo large elastic deformations.
p53-dependent inhibition of FKHRL1 in response to DNA damage through protein kinase SGK1 (2004)

FKHRL1 (FOXO3a) and p53 are two potent stress-response regulators. Here we show that these two transcription factors exhibit "crosstalk" in vivo. In response to DNA damage, p53 activation led to FKHRL1 phosphorylation and subcellular localization change, which resulted in inhibition of FKHRL1 transcription activity. AKT was dispensable for p53-dependent suppression of FKHRL1. By contrast, serum- and glucocorticoid-inducible kinase 1 (SGK1) was significantly induced in a p53-dependent manner after DNA damage, and this induction was through extracellular signal-regulated kinase 1/2-mediated posttranslational regulation. Furthermore, inhibition of SGK1 expression by a small interfering RNA knockdown experiment significantly decreased FKHRL1 phosphorylation in response to DNA damage. Taken together, our observations reveal previously unrecognized crosstalk between p53 and FKHRL1. Moreover, our findings suggest a new pathway for understanding aging and the age dependency of human diseases governed by these two transcription factors.
