QUANTITY (1978)

As length is a property of vowels, quantity is a property of syllables; and although there are connexions between length and quantity in Latin, the two properties are to be clearly distinguished.
Expert systems in insurance underwriting: model development and application (1987)

The paper examines the work of Dr. Gary A. Wicklund and doctoral student Ms. Roberta M. Roth of the University of Iowa in the development and implementation of an insurance underwriting expert system for a Midwestern insurance company. The underwriting function reviews applicant data for determination of insurability. The feasibility of utilizing an expert system in this area was examined and determined to be practical, and development of a prototype was initiated.
Automated Depression Diagnosis Based on Deep Networks to Encode Facial Appearance and Dynamics (2017)

As a severe psychiatric disorder disease, depression is a state of low mood and aversion to activity, which prevents a person from functioning normally in both work and daily lives. The study on automated mental health assessment has been given increasing attentions in recent years. In this paper, we study the problem of automatic diagnosis of depression. A new approach to predict the Beck Depression Inventory II (BDI-II) values from video data is proposed based on the deep networks. The proposed framework is designed in a two stream manner, aiming at capturing both the facial appearance and dynamics. Further, we employ joint tuning layers that can implicitly integrate the appearance and dynamic information. Experiments are conducted on two depression databases, AVEC2013 and AVEC2014. The experimental results show that our proposed approach significantly improve the depression prediction performance, compared to other visual-based approaches.
Measurement and application of arterial stiffness in clinical research: focus on new methodologies and diabetes mellitus. (2003)

The excess risk of cardiovascular disease in patients with Type 2 diabetes mellitus remains largely unexplained. Arterial stiffness, an early feature of diabetic vasculopathy involving several mechanisms, results in impaired arterial compliance, and has recently been proposed as a powerful independent predictor of cardiovascular disease. Increased arterial stiffness can contribute to the development and progression of hypertension, left ventricular hypertrophy and dysfunction, and to decreased myocardial perfusion, all of which are highly prevalent in Type 2 diabetes mellitus. Large artery stiffening has been demonstrated in Type 2 diabetes using several different methods including measurement of central pulse wave velocity, or estimation of aortic compliance, a technically demanding technique requiring the simultaneous measurement of stroke volume and diastolic pressure decay. Increased arterial stiffness of smaller arteries is also an important contributor to systemic arterial stiffness and cardiovascular risk. Increasing demand by clinical researchers for measurement of arterial stiffness has led to the development and commercial availability of highly practicable techniques. These new techniques, which utilise different aspects of the pulse pressure waveform, are simple, reliable and reflect both large and small vessel stiffness. They offer new tools for identifying patients at increased risk of developing cardiovascular complications including those with established diabetes. In this article we introduce the reader to the concepts of arterial stiffness, the significance of arterial stiffness for diabetes, and the new techniques that may potentially be useful for clinical researchers or practitioners.
Secondary Electron Emission from Germanium (1954)

Secondary emission by electron bombardment has been measured for single crystals of Ge with $p\ensuremath{-}n$ junctions. Maximum yield was found in the range $\ensuremath{\delta}=1.15\ifmmode\pm\else\textpm\fi{}0.03$, at ${V}_{p}\ensuremath{\approx}500$ volts and room temperature. Increasing temperature decreased the yield because of a small interaction between the internal secondaries and the lattice. The most probable energy of emission was 1-2 ev. There was no change in yield with donor or acceptor concentration up to ${10}^{19}$/${\mathrm{cm}}^{3}$, and in particular there was no detectable effect of the space-charge fields under the surface. These results form the basis for discussion of the secondary emission process in semiconductors as compared with metals and insulators.
Calibrating the Six-Port Reflectometer by Means of Sliding Terminations (1978)

The six-port technique promises to have a major impact on the next generation of automatic network analyzers because complex heterodyne methods may be replaced by simple amplitude detectors. This projection, however, is predicated upon the existence or development of calibration techniques which permit one to conveniently and accurately obtain the parameters which characterize the six-port. This paper describes a number of substantial refinements to a previously described procedure which is based upon the use of sliding terminations.
Non-dipping blood pressure in normotensive patients with Obstructive Sleep Apnea (1999)

To investigate circadian blood pressure profiles in normotensive patients with moderate te severe obstructive sleep apnea (OSA), in relatien te their apnea indices and left ventricular parameters, we studied twenty one male patients with clinic bleed pressures of 140/90 mmHg. They were matched for age and body mass index (BMI) and all were heavy snorers. They underwent overnight polysomnography, 24 h non-invasive arterial blood pressure monitoring (ABPM) and echocardiography. Patients with a nocturnal reductien in average daytime systolic and diastolic blood pressure of‘ less than 10% were considered non-dippers. Nine patients were non-clippers and 12 were clippers. In the non-dipper group asleep systolic and blood pressure were significantly higher than in the dipper group, (P< 0.0001 and P< 0.01 respectively), There were at significant differences between the apne of hypopnea (AHI) and the oxygen desaturatien (ODI) indices of the dipper and the non-dipper groups. However, left ventricular parameters were significantly higher in the non-dipper than in the dipper group: left ventricular mass index (LVMI, p< 0.001, posterier wall thickness (PWT, p< 0.00 1 ), interventricular septal thickness (IVST, P < 0.00 1 ) and relative wall thickness (RWT, P< 0.01). In this preliminary study an absent or reduced blood pressure fall during sleep in normotensive patients with moderate to severe 0SA cannot be explained by the severity of the apnea alone. Left ventricular hypertrephy, though may be a sequel te the non-dipper situation may also be the cause of it.
Radio Resource Sharing Among Users in Hybrid Access Femtocells (2014)

A problem related to deployment of femtocells is how to manage access of users to radio resources. On one hand, all resources of the femtocell can be reserved for users belonging to a closed subscriber group (CSG), which is a set of users defined by a femtocell subscriber. This approach, known as closed access, however, increases interference to users not included in the CSG as those users do not have a permission to access this femtocell. Contrary, resources can be shared by all users with no priority in an open access mode. In this case, the femtocell subscriber shares radio as well as backhaul resources with all other users. Thus, throughput and quality of service of the subscriber and the CSG users can be deteriorated. To satisfy both the CSG as well as non-CSG users, a hybrid access is seen as a compromise. In this paper, we propose a new approach for sharing radio resources among all users. As in common cases, the CSG users have a priority for usage of a part of resources while rest of the resources is shared by all users proportionally to their requirements. As the simulation results show, the proposed resource sharing scheme significantly improves throughput of the CSG users and their satisfaction with granted bitrates. At the same time, throughput and satisfaction of the non-CSG users is still guaranteed roughly at the same level as if conventional sharing schemes are applied.
Combination of rod and cone inputs in parasol ganglion cells of the magnocellular pathway (2010)

This study investigates how rod and cone inputs are combined in the magnocellular (MC) pathway in the mesopic luminance range, when both rods and cones are active. Responses of parafoveal MC ganglion cells from macaque retina were measured as a function of temporal frequency (0.62-20 Hz) or contrast (0.05-0.55) at mesopic light levels (0.2, 2, 20, and 200 td). Stimuli were of three modulation types: (1) isolated rod stimuli (only rod signals were modulated), (2) isolated cone stimuli (only cone luminance signals from long- and middle-wavelength sensitive cones were modulated), and (3) combined rod and cone stimuli (both rod and cone luminance signals were modulated in phase, as with conventional stimuli). The results showed that under mesopic conditions, the relative rod and cone inputs to the MC cells varied with light level and they are combined linearly prior to saturation. Further, rod contrast gain is relatively stable over the mesopic range while cone contrast gain increased with light level. Finally, the measured rod and cone inputs are consistent with the measured human temporal contrast sensitivity functions under comparable stimulation conditions.
Oxidative stress and enzyme activity in ambulatory renal patients undergoing continuous peritoneal dialysis (1998)

Some parameters indicating the possibility of oxidative stress in chronic renal failure patients (CRF) undergoing continuous ambulatory peritoneal dialysis (CAPD), are presented in this study. Oxidative stress appears to be lower than in hemodialysis patients. In a group of CRF patients and in a control group malondialdehyde (MDA) was determined as an indicator of red-blood-cell membrane lipid peroxidation. Also, the three glutathione forms, total (GST), oxidated (GSSG) and reduced (GSH) and the levels of glutathione peroxidase (GPX), the levels of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) have been measured. Significantly higher MDA values (p < .05) have been found in CRF patients when compared to controls. The three forms of glutathione and GPX are also significantly decreased in the CRF group (p < .05 and p < .001, respectively). The levels of SOD and CAT are increased with respect to the control group (p < .001).
Wireless MPEG-4 video communication on DSP chips (2000)

We discuss the design and implementation of wireless video communication systems on DSPs. We cover both video coding and the channel coding aspects of the problem. The emphasis of the article is on highlighting the issues involved both from an algorithmic standpoint as well as from a DSP standpoint. We discuss the first DSP implementation, to the authors' knowledge, of the MPEG-4 simple profile video standard. We give an overview of DSPs and highlight the salient features that make them especially well-suited for wireless applications. We describe MPEG-4 simple profile video coding noting that in order to facilitate interoperability, it is important that wireless devices use standardized compression algorithms. We discuss our implementation of the MPEG-4 simple profile video codec on Texas Instruments' TMS320C54x DSP and discuss the issues involved. We highlight some general and application-specific DSP instructions on the TMS320C54x DSP that enable us to implement the core operations in the video coder efficiently, often in a single cycle, with minimal control overhead. We describe the performance of MPEG-4 video compression for a variety of content and formats. We give a description of channel coding with the H.223 standard. Then, we describe several channel coding experiments using both unequal and equal protection on MPEG-4 video sent through a simulated GSM channel. Unequal error protection, which ensures fewer errors in the important portions of the MPEG-4 video bitstream, provides improved quality when compared to equal error protection under harsh error conditions.
Visualizing reference patterns for solving memory leaks in Java (2000)

Many Java programmers believe that they do not have to worry about memory management because of automatic garbage collection. In fact, many Java programs run out of memory unexpectedly after performing a number of operations. A memory leak in Java is caused when an object that is no longer needed cannot be reclaimed because another object is still referring to it. Memory leaks can be difficult to solve, since the complexity of most programs prevents us from manually verifying the validity of every reference. In this paper we show a new methodology for finding the causes of memory leaks. We have identified a basic memory leak scenario which fits many important cases. In this scenario, we allow the programmer to identify a period of time in which temporary objects are expected to be created and released. Using this information we are able to identify objects that persist beyond this period and the references which are holding on to them. Scaling this methodology to real-world systems brings additional challenges. We propose a novel combination of visual syntax and reference pattern extraction to manage this additional complexity. We also describe how these techniques can be applied to a wider class of memory problems, including the exploration of large data structures. These techniques have been implemented and have been proven successful on large projects. Copyright © 2000 John Wiley & Sons, Ltd.
High-sensitivity high-stability silicon photodiodes for DUV, VUV and EUV spectral ranges (2011)

In this paper, the optical and electrical performance of a newly developed silicon photodiode based on pure boron CVD technology (PureB-diodes) is introduced. Due to their extremely shallow p-n junction, with the depletion zone starting only a few nanometers below the surface, and nm-thin pure-boron-layer coverage of the anode surface, PureB-diodes have so far demonstrated the highest reported spectral responsivity in all sub-visible ultraviolet (UV) ranges: DUV (deep ultraviolet), VUV (vacuum ultraviolet) and EUV (extreme ultraviolet), covering a spectrum from 220 nm down to few nanometersMoreover, the measured responsivity at 13.5 nm wavelengths (EUV) approaches the theoretical maximum (~0.27A/W). PureB-diodes also maintain excellent electrical characteristics, with saturation-current values typical for high-quality silicon diodes, and a high breakdown voltage. Experimental results have demonstrated the extremely high radiation hardness of PureB-diodes when exposed to high EUV radiant exposures in the order of a few hundred kJ/cm<sup>2</sup>. No change in the responsivity is observed within the experimental uncertainty. In the more challenging DUV and especially VUV ranges, PureB-diodes demonstrate a slight initial drop of responsivity (1 to 2%), after which they stabilizes their performance.
Towards faster string matching for intrusion detection or exceeding the speed of Snort (2002)

Network intrusion detection systems (NIDS) often rely on exact string matching techniques. Depending on the choice of algorithm, implementation and the frequency with which it is applied, this pattern matching may become a performance bottleneck. To keep up with increasing network speeds and traffic, NIDS can take advantage of advanced string matching algorithms. We describe the effectiveness of a significantly faster approach to pattern matching in the open source NIDS Snort.
<title>Specular spectroscopic profilometry for the sub-0.18-um polySi-gate processes</title> (2000)

Specular Spectroscopic Profilometry (SSP), or Phase Profilometry (PP), has been proposed for in-situ/in-line patterned thin-film measurements. This is usually accomplished by using a rigorous electromagnetic theory to simulate the optical responses of gratings with different profiles, and by using spectroscopic ellipsometry/reflectometry to measure 1-D gratings. In this paper, specular spectroscopic profilometry is applied in DUV lithography and etch processes as a profile extraction metrology. One focus-exposure experiment is conducted by using 0.18 micrometer lithography technology, another focus-exposure experiment is conducted by using 0.18 micrometer lithography and etch technology. Comparison between the measurement from CD-SEM, CD-AFM and PP are discussed and explained.
Requirements and Analysis of Extended HTTP Digest Access Authentication (2013)

Authenticating to an online service is usually done by providing a username and password in some protected form so that the server can verify that those credentials correspond to a registered identity authorised for access. For the average Internet user, managing one’s online identities is challenging. Nearly every password protected web service advises its users to come up with a sufficiently complex password, which is not to be used elsewhere. As the number of associations with online services increases, so too does the number of online identities that the user has to remember. Identity overload is one of the greatest challenges for Internet users. The result may be that the user reuses difficult passwords for those of his online accounts that protect high value information, and uses passwords that are easily remembered (and easily guessed) for the protection of lower value information.\n\nThe main goal of this thesis is to investigate local user-centric identity management and propose a simple, secure and user friendly authentication mechanism. The mechanism relies on an external offline personal authentication device called “OffPAD”, which acts as a trusted platform external to the terminal. From this device, the user may authenticate to services and manage his online identities. We argue that the approach of handling critical actions on an external secure device provides increased security and usability with regard to both the authentication process itself, as well as the storage and handling of identities. \n\nThe OffPAD device can be used to automatically authenticate its holder to any supported web service to which he or she is registered. We will present an extension of the HTTP Digest Access Authentication scheme that facilitates unobtrusive and automated authentication, while still adhering to password policies. We will look at how we can increase security and suggest improvements for modernizing the (ageing) digest authentication standard in particular, with regard to storage and handling of credentials. We will also discuss how identity management can be more user-centric, thus user friendly, alleviating the cognitive load of managing passwords.\n\nHTTP Digest Access Authentication is used as the authentication scheme in every example and in the prototype implementation. It was selected for its simplicity, extendibility and abilities: especially its ability to function with both clear text and hashed user credentials at the endpoints.
Recent advances in herbal medicine for treatment of liver diseases (2011)

Out of the several leads obtained from plant sources as potential hepatoprotective agents, silymarin, andrographolide, neoandrographolide, curcumin, picroside, kutkoside, phyllanthin, hypophyllanthin, and glycyrrhizin have been established as potent hepatoprotective agents. The hepatoprotective potential of several herbal medicines has been clinically evaluated. Significant efficacy has been seen with silymarin, glycyrrhizin and Liv-52 in treatment of hepatitis, alcoholic liver disease and liver cirrhosis.
Query interoperation among object-oriented and relational databases (2002)

We develop an efficient algorithm for the query interoperation among existing heterogeneous object-oriented and relational databases. Our algorithm utilizes a canonical deductive database as a uniform representation of object-oriented schema and data. High-order object queries are transformed to the canonical deductive database in which they are partially evaluated and optimized, before being translated to relational queries. Our algorithm can be incorporated into object-oriented interfaces to relational databases or object-oriented federated databases to support object queries to heterogeneous relational databases.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Front-End ASIC for a Silicon Compton Telescope (2007)

We describe a front-end application specific integrated circuit (ASIC) developed for a silicon Compton telescope. Composed of 32 channels, it reads out signals in both polarities from each side of a Silicon strip sensor, 2 mm thick 27 cm long, characterized by a strip capacitance of 30 pF. Each front-end channel provides low-noise charge amplification, shaping with a stabilized baseline, discrimination, and peak detection with an analog memory. The channels can process events simultaneously, and the read out is sparsified. The charge amplifier makes uses a dual-cascode configuration and dual-polarity adaptive reset. The low-hysteresis discriminator and the multi-phase peak detector process signals with a dynamic range in excess of four hundred. An equivalent noise charge (ENC) below 200 electrons was measured at 30 pF, with a slope of about 4.5 electrons / pF at a peaking time of 4 mus. With a total dissipated power of 5 mW the channel covers an energy range up to 3.2 MeV.
Aequorin measurements of free calcium in single mammalian cells (1983)

The calcium-triggered photoprotein aequorin has been used as a sensitive indicator of cytoplasmic free calcium in cells of relatively large size. We describe here several novel modifications to the technique that make it possible to detect resting levels of free calcium in single mammalian oocytes, fibroblasts and granulosa cells. Concentrations of free calcium as low as 1 X 10(-7) M have been measured in single fibroblasts, corresponding to a detection limit of 10(-18)mol.
