P‐64: Assessment of Colloid Liquid Crystal Composites for Display Applications (2000)

Abstract The aim of the present paper is to perform a thorough and systematic survey of the optical properties of colloid liquid crystal composites with a view to assessing their potential to enable innovations or improvements in display devices. An introduction to the structure and properties of these materials is presented and applications for specific device types (twist‐nematic, guest‐host, and cholesteric) are considered.
Three-port micro-inverter with power decoupling capability for Photovoltaic (PV) system applications (2014)

This paper proposes a new single-phase inverter topology for Photovoltaic (PV) applications. The capability of decoupling the double-line-frequency ripple, using a small capacitance, is the main feature of the proposed topology. This allows for using a film capacitor instead of an electrolytic capacitor, resulting in higher inverter reliability. Additionally, no extra circuitry is needed to manage the transformer leakage energy.
Risk, Data and the Barcodes of Finance (2017)

The failure of Lehman Brothers uncovered a shocking fact that after six decades of automation there are no global standards for the identity of financial market participants nor their financial products. Bankruptcy attorneys and forensic accountants tried to understand Lehman’s exposure to others and others’ exposure to Lehman. There was no consistency in identifying Lehman as a counterparty; no understanding of what relationships Lehman had with others; no mechanism to associate all of Lehman’s products and businesses into a total view of the exposure others had to Lehman should it fail. In effect, no one… not regulators nor creditors nor counterparties could see into Lehman’s exposure to risk. This paper illuminates a fundamental component of the financial system that goes largely unrecognized as a key pillar of finance, non-standardized financial transaction data. Financial transactions lack unique, universal and unambiguous identifying codes for the supply chain of financial market participants and the products they manufacture, issue, own, process, and trade. Imagine if every supermarket had a different barcode for the same product on its shelves or a different code for the producer or supplier of the product. Walmart, FedEx and Amazon could not exist. This failure has exasperated researchers, analysts, financial institutions and regulators who are forced to map and scrub this data before aggregating financial transactions for performance, risk and regulatory reporting. Considerable risks, costs and delays in receiving payment are inherent in this reconciliation process. This paper explores the history, current status, issues, work yet to be done, and recommendation by the author to create financial industry identity standards. The Barcodes of Finance will enable an automated means to aggregate risk data so firms can reduce risk and costs, and regulators can oversee the largest systemically important global financial firms.
Low-power motion vector estimation using iterative search block-matching methods and a high-speed non-destructive CMOS image sensor (2002)

In this paper, motion vector (MV) estimation methods with high-speed intermediate pictures for low-power video compression are proposed. The intermediate pictures are obtained by a special type of CMOS image sensor. An adaptive iterative-search block matching is proposed to obtain precise MVs of video-rate pictures from high-speed intermediate pictures with the reduced computational complexity. The sensor captures high-speed intermediate pictures without destructing signal charge and video-rate pictures with full signal accumulation time. The proposed active pixel sensor using bidirectional multiple charge transfer is useful for the nondestructive intermediate imaging with a reduced fixed pattern noise. The image sensor chip has been implemented by using 0.35-/spl mu/m CMOS technology. It operates with 3.3 V and captures 480 frames/s high-speed nondestructive intermediate pictures and 30 frame/s fully accumulated video-rate pictures. The proposed adaptive iterative-search block matching has a comparable precision to a full search block matching with reduction of computational complexity by a factor of about 1/13, on average. It also reduces the data-loading rate from the memory by a factor of about 1/4.
Toxicoproteomics and its application to human health risk assessment (2007)

Toxicoproteomics is the use of proteomic technologies to better understand environmental and genetic factors, toxic mechanisms, and modes of action in response to acute exposure to toxicants and in the long-term development of diseases caused or influenced by these exposures. Use of toxicoproteomic technologies to identify key biochemical pathways, mechanisms, and biomarkers of exposure and toxicity will decrease the uncertainties that are associated with human health risk assessments. This review provides an overview of toxicoproteomics from human health risk assessment perspectives. Key toxicoproteomic technologies such as 2-D gel-based proteomic methods and toxicoproteomic approaches are described, and examples of applications of these technologies and methodologies in the risk assessment context are presented. The discussion includes a focus on challenges and future directions.

Viscoelastic Fluid Flow in the Entrance of A Tube (1967)

A semi-empirical method is presented which permits the prediction of the entrance length and entrance pressure drop of laminar flow of non-Newtonian viscoelastic fluid into the entrance of a circular tube. The only information required for this calculation is the knowledge of pipe diameter, mean velocity, and rheological parameters of the fluid. In addition, data are presented concerning the laminar flow of aqueous solutions of ET-597, a Dow Chemical long-chain polymer, both in the entrance region and in the established zone. Data for laminar flow in the established zone indicate that the Fanning friction factor, f, and the generalized non-Newtonian Reynolds number, R', have the relationship f = 16/R'. Also, it is found that above a certain mean velocity, which is a function of polymer concentration and pipe diameter, the pressure losses become less for polymeric solutions than for water.
LEUCOSTOMA TOLERANCE IN PEACH: FUNGAL ISOLATE × PEACH GENOTYPE (1990)

Seven peach clones which were previously identified as resistant, intermediate, or susceptible to Leucostom a persoonii were screened against 3 different L. persoonii and L. cinct a isolates to determine if the resistant reaction was fungal species and/or isolate specific. Canker necrotic length varied significantly with the most resistant genotypes; NJ672017002 (1-8) and Yennoh (1-39) having the shortest canker lengths. The virulence of the fungal species and isolates also varied significantly and there was a significant species/isolate × peach genotype interaction. However, this interaction tended to be among the intermediate and susceptible genotypes with the 2 resistant peach genotypes least affected by all isolates.
Personalized support for well-being at work: an overview of the SWELL project (2019)

Recent advances in wearable sensor technology and smartphones enable simple and affordable collection of personal analytics. This paper reflects on the lessons learned in the SWELL project that addressed the design of user-centered ICT applications for self-management of vitality in the domain of knowledge workers. These workers often have a sedentary lifestyle and are susceptible to mental health effects due to a high workload. We present the sense–reason–act framework that is the basis of the SWELL approach and we provide an overview of the individual studies carried out in SWELL. In this paper, we revisit our work on reasoning: interpreting raw heterogeneous sensor data, and acting: providing personalized feedback to support behavioural change. We conclude that simple affordable sensors can be used to classify user behaviour and heath status in a physically non-intrusive way. The interpreted data can be used to inform personalized feedback strategies. Further longitudinal studies can now be initiated to assess the effectiveness of m-Health interventions using the SWELL methods.
Intensive Insulin Therapy Increases the Risk of Hypoglycemia in Neurocritical Care Patients (2011)

Implementation of intensive insulin therapy protocols in neurocritical care patients not only seems to increase the time spent in the desired blood glucose range, but also seems to increase the risk of hypoglycemia. The risk of hypoglycemia strongly depends on characteristics of the intensive insulin therapy protocol.
A Sensorless Adaptive Maximum Power Point Extraction Method With Voltage Feedback Control for Small Wind Turbines in Off-Grid Applications (2015)

Due to the ever growing global energy demand and pollution levels, clean and renewable alternative energy resources, such as wind, have become indispensable for preserving the planet for future generations. With wind being an unpredictable resource, it is imperative that wind systems extract as much power from the wind as possible while it is available. The conventional maximum power point tracking (MPPT) algorithms that use predetermined mathematical relationships to represent a specific wind system's power/torque characteristics suffer the drawback of deteriorated efficiency over time whereas the perturb and observe algorithms are susceptible to logical errors when subjected to frequent atmospheric variations. In order to solve the aforementioned drawbacks as well as to reduce the cost of the sensing network required to achieve MPPT, this paper proposes a novel sensorless slope-assisted MPPT algorithm that is able to avoid logical errors attributed to wind fluctuations by detecting and identifying atmospheric changes. Atmospheric changes are detected by a state observer by monitoring the generator output power, the ac/dc rectifier output voltage, and the rate of change of the power-voltage ratio without the need for anemometers and any generator speed sensors. The detailed description of the proposed MPPT control logic will be provided in this paper. The functionality of the proposed control method is verified through the simulation results on a 3-kW system, as well as the experimental results on a proof-of-concept 200-W prototype.
Atrial Myocyte NLRP3/CaMKII Nexus Forms a Substrate for Postoperative Atrial Fibrillation (2020)

Preexisting Ca<sup>2+</sup>-handling abnormalities and activation of NLRP3-inflammasome/CaMKII signaling are evident in atrial cardiomyocytes from patients who subsequently develop POAF. These molecular substrates sensitize cardiomyocytes to spontaneous Ca<sup>2+</sup>-releases and arrhythmogenic afterdepolarizations, particularly upon exposure to inflammatory mediators. Our data reveal a potential cellular and molecular substrate for this important clinical problem.
Spatial frequency content of focused ultrashort pulsed beams* (2002)

The generalized pupil concept has proved useful for representation of focused monochromatic fields. The generalized pupil can also be used to describe, and give insight into, the focusing of different types of ultrashort pulses, including Gaussian beams and focus wave modes.
Signalling Quality: An Assessment of the Effectiveness of Regulator Quality Ratings for Care Homes (2020)

When making a choice regarding care homes, potential service users or their family members face problems associated with information asymmetry. Given the credence nature of care home services, many aspects of quality cannot be assessed prior to use. In the absence of a mechanism to assess service quality two main problems can arise. First, users are not able to distinguish between good-quality providers and poor-quality providers, and second, providers of good-quality services are unable to credibly provide accurate information to users to distinguish them from poor-quality providers. In such a situation, both users and providers of high-quality services will welcome measures or effective ‘signals’ that would allow them to differentiate service quality. In England, this role is fulfilled by the Care Quality Commission, through inspections and provision of quality ratings. Quality ratings produced by the regulator have a dual purpose. They provide information about quality for potential stakeholders who may be interested in using the service and they provide feedback for care home service providers to encourage service quality improvement. If quality ratings are to effectively remove problems of information asymmetry, they must be effective in both purposes. Using signalling theory as the basis for a range of quantitative methods, this research assesses the effectiveness of quality ratings provided by the regulator for all care homes, as market signals of quality. Based on the assessment of the three dimensions of an effective signal (signal cost, signal observability and signal consistency), the study finds that regulator quality ratings may not be an effective market signal. Whilst the study finds that quality ratings of some service providers improves after inspection, no improvements are made by a greater number of care homes. Furthermore, the study also finds a positive association between quality ratings and demand for care home places, however, the evidence also suggests that changes in demand are caused mostly by the regulator’s own enforcement actions. In addition to having some issues with internal consistency between quality ratings and inspection reports, evidence suggests that regulator quality ratings are mainly fulfilling the role of a feedback signal for regulatory scrutiny. There is a need for the regulator to consider the informational gain from its quality ratings for potential service users of care homes. If service users are to benefit from quality ratings and inspection reports, these must be internally consistent and easily understandable by those accessing the information.
A class of convergent algorithms for resource allocation in wireless fading networks (2010)

Optimal and reduced-complexity near-optimal algorithms are developed for the design of wireless networks in the presence of fading. The physical layer is interference-limited, whereby network terminals treat interference as noise. Optimal wireless network design amounts to joint optimization of application-level rates, routes, link capacities, power consumption, and power allocation across frequency tones, neighboring terminals, and fading states. The present contribution shows how recent results establishing the optimality of layered architectures can be realized in practice by developing physical layer resource allocation algorithms that are seamlessly integrated into layered architectures without loss of optimality. Specifically, the provably convergent algorithms yield (near-)optimal end-to-end rates, multicommodity flows, link capacities, and average powers. These design variables are obtained offline, and are subsequently used for control during network operation.

Abstract — This paper presents an overview of the Radio Resource Management (RRM) functionalities needed for Non-Conventional and Low-Cost Networks. These types of networks are characterized by increased cooperation between different types of networks and providers and they are believed to play a fundamental role for future wireless network networking. The paper describes three specific concepts, which latter is used to identify new RRM challenges. In addition, it identifies the relation between the RRM challenges and the Ambient Networks architecture and functionalities, in particular the multiradio resource management functionality. 1
Metal Schottky Barriers on Hydrogenated Amorphous Ge/Si Superlattices (1987)

The barrier heights and junction properties of Pt Schottky barriers on hydrogenated amorphous Ge/Si superlattices have been characterized for films with individual layer thickness from ∼5 to 30 Å. The electronic properties of these junctions, which allow efficient extraction of photogenerated carriers, are explained in terms of the quantum shifts in the conduction band and the densities of gap states in the Ge layers.
A review on fatty acid desaturases of psycrophilic bacteria and unsaturated fatty acids (2014)

Fatty acid desaturase enzymes function in the introduction of a double bond into fatty acyl chains to produce unsaturated fatty acids. Unsaturated fatty acids play significant role in maintaining the right structure and functioning of biological membranes of all organisms. Psychrophilic bacteria survive low temperatures with 15 °C and 20 °C as the optima and maxima respectively. Under these conditions, the bacteria modulate their membrane fluidity by means of synthesizing more unsaturated fatty acids using desaturase enzymes. Consequently, transport of nutrients and metabolic wastes in and out of the cell are properly regulated. Moreover, unsaturated fatty acids are directly involved in cellular processes like membrane fusion and fission, signalling and energy storage. Furthermore, unsaturated fatty acids have proven antitumor effect, protection against cardiac diseases, antibacterial and anti-inflammatory properties. This review surveys the general aspects of fatty acid desautrases, desaturases of psychrophilic bacteria, unsaturated fatty acids and their roles.
Glucose-regulated stresses cause degradation of DNA topoisomerase II? by inducing nuclear proteasome during G1 cell cycle arrest in cancer cells (1999)

The glucose-regulated stress response of cancer cells leads to a decreased expression of DNA topoisomerase IIalpha (topo IIalpha) and a cell cycle arrest at the G1 phase. In this study, we found that the topo IIalpha decrease occurred specifically during the G1 arrest in human colon adenocarcinoma HT-29 cells. The intracelluar level of topo IIalpha in HT-29 cells was relatively constant regardless of cell cycle position in the exponentially growing state, determined using a centrifugal elutriation technique and synchronizing the cells with a mitotic inhibitor nocodazole. Interestingly, when the cell cycle was arrested in the M phase by nocodazole, the topo IIalpha level remained high even in stressed cells. After the stressed cells were released from the M phase, topo IIalpha steeply decreased along with cell cycle progression followed by the next G1 arrest. This decrease in nuclear topo IIalpha protein was completely inhibited by selective inhibitors for proteasome. Furthermore, we found that proteasome activity was elevated three to fourfold in the nuclear extract of stressed cells over unstressed cells. Accordingly, there were increased amounts of nuclear proteasome subunits, although total intracellular content of the subunits did not change in stressed cells. These findings indicate that the expression of topo IIalpha in stressed cells is downregulated at the G1 phase by proteasome-mediated degradation and that the proteolysis of topo IIalpha can be facilitated by the nuclear accumulation of proteasome.
