MMSE equalization for UMTS HSDPA (2003)

The impact of 'advanced' mobile receivers incorporating dual-port antenna diversity and chip-rate equalization is assessed in terms of UMTS Release-5 high speed downlink packet access (HSDPA) link and system throughput. The addition of a second antenna port to the RAKE receiver increased the link-level throughput under 3GPP RAN WG4 test conditions by 25-100%, while a chip-rate minimum mean square error (MMSE) equalizer increased throughput by approximately the same amount for the time-dispersive (Pedestrian-B) channel. Assuming ideal channel estimation, the improvement in sector throughput was between 25-90% depending on the receiver configuration. Neglecting TCP, user throughput increased 50 to 100% when either receives diversity or MMSE equalization was applied, with the throughput increase becoming 100 to 200% for the dual-port MMSE case. When TCP was included, however, user throughput improvement reduced to 20% (MMSE equalizer), 33% (dual-port RAKE) and 45% (dual-port MMSE) respectively for the same system load.
Exercise Training as a Treatment for Chronic Inflammation in the Elderly (2009)

Persistent subclinical inflammation predisposes to chronic disease, as well as the development of sarcopenia and disability, in frail elderly. Thus, the inflammatory pathway is a potential target for interventions to reduce aging-related disease and disability. This article highlights emerging data suggesting that increasing physical activity could be effective for reducing chronic inflammation in the elderly.

Channel Equalization (2002)

28.1 Introduction The terminology line coding originated in telephony with the need to transmit digital information across a copper telephone line; more specifically, binary data over a digital repeatered line. The concept of line coding, however, readily applies to any transmission line or channel. In a digital communication system, there exists a known set of symbols to be transmitted. These can be designated as {mi}, i = 1, 2,.,N, with a probability of occurrence {pi}, i = 1, 2,.,N, where the sequentially transmitted symbols are generally assumed to be statistically independent. The conversion or coding of these abstract symbols into real, temporal waveforms to be transmitted in baseband is the process of line coding. Since the most common type of line coding is for binary data, such a waveform can be succinctly termed a direct format for serial bits. The concentration in this section will be line coding for binary data.
[Protein E 98-113 sequence is a fusion site of tick-borne encephalitis virus with cellular membrane]. (1998)

The synthetic peptide with the conservative 98-113 sequence of protein E of tick-borne encephalitis virus was studied in order to elucidate its role in the functioning of flaviviruses. The peptide was shown to inhibit the in vitro infection of macrophages with the virus. An antibody that specifically binds this peptide was found among the set of monoclonal antibodies produced against protein E. This antibody was found to prevent penetration of the virus into liposomes. A correlation was found between our results and data on the spatial structure of protein E and its interspecies homology. The protein E 98-113 sequence of the tick-borne encephalitis virus was found to be the fusion site of the viral envelope with a cellular membrane.
FRUCTOSE CONCENTRATIONS IN SEMINAL PLASMA FROM MEN WITH NONOBSTRUCTIVE AZOOSPERMIA (2002)

Fructose is secreted from the seminal vesicles and the accessory sex glands. It is the major carbohydrate source in seminal plasma and essential for normal sperm motility. The objective of this prospective descriptive study was to measure fructose concentrations in seminal plasma from men with obstructive and non-obstructive azoospermia, as determined by serum FSH, and to compare these with fructose concentrations in seminal plasma from men with normal semen parameters. A higher median fructose concentration was observed in seminal plasma from men with azoospermia and a raised serum FSH (3.22 mg/ml) compared to that from men with azoospermia and normal serum FSH (2.30 mg/ml) (p < 0.0001) and to that from normal controls (2.50 mg/ml) (p < 0.0002). This is the first report of increased seminal plasma concentrations of fructose in samples from men with non-obstructive azoospermia. This is either due to a decreased fructose metabolism associated with the azoospermia or, more likely, an increased fructose production from the seminal vesicles.
Structure Analysis of Acetylated and Non-acetylated O-Linked MUC1-Glycopeptides by Post-source Decay Matrix-assisted Laser Desorption/Ionization Mass Spectrometry (1997)

We have investigated the potential of structural elucidation of O-linked glycopeptides by post-source decay matrix-assisted laser desorption ionization mass spectrometry (PSD-MALDI-MS). In order to establish detailed fragmentation patterns and to dissect fragment ions with and without carbohydrate content, the same O-linked MUC1-derived glycopeptides with acetylated and non-acetylated sugars were analysed and compared. Furthermore, we were interested to examine possible differences in the fragmentation between glycopeptides with acetylated and non-acetylated sugars. The obtained PSD-MALDI-MS spectra showed a rather complete set of fragmentation data which allows to localize the glycan on the peptide, in parallel with sequencing a short glycan and the backbone peptide. Fragmentations of the sugars were dominated by inter-ring cleavages at the glycosidic bond. Intra-ring cleavage did also occur from the non-reducing end, but to a much lower extent. The fragmentation of the peptide backbone was not changed either by acetylated or non-acetylated sugars. Glycosylated peptide fragments occurred as fully glycosylated fragment ions, partially deglycosylated ions and completely deglycosylated ions, and was not influenced by the acetylation of sugars. However, differences occurred in the quality and quantity of fragment ions from the non-reducing end of the glycan part when comparing acetylated with non-acetylated glycopeptides.
Active filtering capability of WECS with DFIG for grid power quality improvement (2008)

A doubly fed induction generator (DFIG) with active filtering capability is presented. We proposed to make use of the DFIG and the associated rotor side converter (RSC) to control stator active and reactive power and simultaneously compensate the most significant and troublesome harmonic currents of the utility grid. We presented a new high selectivity harmonic isolator based on self tuning filter (STF). Simulation results when filtering the harmonic component of the grid current validate the performances of the harmonic isolator principle and the active filtering capability of the DFIG.
Rule-based Cloud Service Localisation (2013)

The fundamental purpose of cloud computing is the ability to quickly provide software and hardware resources to global users. The main aim of cloud service localisation is to provide a method for facilitating the internationalisation and localisation of cloud services by allowing them to be adapted to different locales. We address lingual localisation by providing a service translation using the latest web-services technology to adapt services to different languages and currency conversion by using realtime data provided by the European Central Bank. Units and Regulatory Localisations are performed by a conversion mapping, which we have generated for a subset of locales. The aim is to provide a standardised view on the localisation of services by using\nruntime and middleware services to deploy a localisation implementation.
Skin perfusion responses to surface pressure-induced ischemia: implication for the developing pressure ulcer. (1999)

This study describes alterations in skin perfusion in response to step increases in surface pressure, before and after long-term (5 hr) exposure to pressure-induced ischemia. A provocative test was developed in which surface pressure was increased in increments of 3.7 mmHg until perfusion reached an apparent minimum by a computer-controlled plunger that included a force cell, a laser Doppler flowmeter to determine perfusion, and a thermistor to monitor skin temperature. Force was applied to the greater trochanters of adult male fuzzy rats. Skin perfusion (n=7) initially increased with low levels of surface pressure (up to 13.9+/-1.9 mmHg) and then decreased with further increases in pressure, reaching minimum (zero) perfusion at 58.2+/-3.64 mmHg. After pressure release, reactive hyperemia (3 x normal) was observed, with levels returning to normal within 15-30 min. The provocative test was then applied after a 5-hr ischemic episode (produced by 92 mmHg) and 3 hr of recovery. A comparison of responses between stressed and unstressed skin revealed: elevated (63%) control perfusion levels; loss of the initial increase in perfusion with low levels of increasing pressure; a depression (45%) in the hyperemic response with delayed recovery time; and a decrease (54%) in amplitude of low frequency (<1 Hz) rhythms in skin perfusion. Skin surface temperature gradually increased both during the control period and the period of incremental increases in surface pressure (total DT=3.3 degrees C). The results suggest a compromised vasodilator mechanism(s). The provocative test developed in this study may have clinical potential for assessing tissue viability in early pressure ulcer development.
Analyzing consistency properties for fun and profit (2011)

Motivated by the increasing popularity of eventually consistent key-value stores as a commercial service, we address two important problems related to the consistency properties in a history of operations on a read/write register (i.e., the start time, finish time, argument, and response of every operation). First, we consider how to detect a consistency violation as soon as one happens. To this end, we formulate a specification for online verification algorithms, and we present such algorithms for several well-known consistency properties. Second, we consider how to quantify the severity of the violations, if a history is found to contain consistency violations. We investigate two quantities: one is the staleness of the reads, and the other is the commonality of violations. For staleness, we further consider time-based staleness and operation-count-based staleness. We present efficient algorithms that compute these quantities. We believe that addressing these problems helps both key-value store providers and users adopt data consistency as an important aspect of key-value store offerings.
The eXtendable Solar Array System: A Modular Nanosatellite Power System (2010)

The eXtendable Solar Array System (XSAS) is a novel CubeSat solar power technology that uses a deployable array for increased solar panel area and gravity gradient stabilization. This system can be packaged into a 1.5U CubeSat configuration and, once deployed, extends out to a maximum of 2 meters. With this additional surface area, XSAS can provide up to five times the amount of power of standard CubeSat configurations as well as provide gravity gradient stabilization. The current version of XSAS has undergone iterated design and testing. In this paper, testing results are presented including ground testing of the apparatus and microgravity deployment. Initial results are provided of the deployment characteristics through position, acceleration and strain measurements and recommendations are made for CubeSat developers working on other deployables based on these findings.

Herbicide-Resistant Crops: Utilities and Limitations for Herbicide-Resistant Weed Management (2010)

Since 1996, genetically modified herbicide-resistant (HR) crops, particularly glyphosate-resistant (GR) crops, have transformed the tactics that corn, soybean, and cotton growers use to manage weeds. The use of GR crops continues to grow, but weeds are adapting to the common practice of using only glyphosate to control weeds. Growers using only a single mode of action to manage weeds need to change to a more diverse array of herbicidal, mechanical, and cultural practices to maintain the effectiveness of glyphosate. Unfortunately, the introduction of GR crops and the high initial efficacy of glyphosate often lead to a decline in the use of other herbicide options and less investment by industry to discover new herbicide active ingredients. With some exceptions, most growers can still manage their weed problems with currently available selective and HR crop-enabled herbicides. However, current crop management systems are in jeopardy given the pace at which weed populations are evolving glyphosate resistance. New HR crop technologies will expand the utility of currently available herbicides and enable new interim solutions for growers to manage HR weeds, but will not replace the long-term need to diversify weed management tactics and discover herbicides with new modes of action. This paper reviews the strengths and weaknesses of anticipated weed management options and the best management practices that growers need to implement in HR crops to maximize the long-term benefits of current technologies and reduce weed shifts to difficult-to-control and HR weeds.
Tracking bacterial movements using a one-dimensional fringe system (1978)

Movements of individual E. coli bacteria in solution are detected by a one-dimensional fringe system formed in the focal region of two crossed laser beams. The time modulation of the scattered light intensity is used to deduce the instantaneous speed of the bacterial motion as it enters into the focal region. A method is described as being capable of testing the isotropic speed distribution function without the complications associated with the finite size and structural effects that influence the interpretation of the conventional light-scattering spectra.
Millimeter-wave Beam Scanning Antennas using Liquid Crystals (2015)

Two Liquid crystal-based reflectarrays that operate at 100 GHz and 125 GHz are presented. The first prototype (100 GHz) is used to validate the modeling and the design procedure proposed for this class of antenna. Experimental validation of the beam scanning is carried out by measuring the received power in a quasi-optical test bench, which is able to rotate the receiver in the horizontal plane. These results are used to design a second prototype antenna (125 GHz) which exhibits 2D beam scanning capabilities with a large bandwidth and scanning range that is sufficient for radar and communications applications.
Oxidation of Alkanes Catalyzed by Different Octahedral Molecular Sieves (1999)

A series of manganese oxide based octahedral molecular sieves (OMS) with different pore openings were used as catalysts to study the oxidization of three organic substrates with different sizes or shapes. The catalysts used are ramsdellite (with 1x2 MnO6 units as tunnel opening), cryptomelane (with 2x2 opening), todorokite (with 3x3 opening), and a 2x4 tunnel structure material. The organic substrates are cyclohexane, hexane, and decalin with tertiary butyl hydrogen peroxide (TBHP) as oxidant and its reduced state tertiary butyl alcohol (TBA) as solvent. The conversions of organic substrates, efficiencies of TBHP, and the rates of organic substrate conversions and rates of TBHP disappearance were systematically studied. The results show that OMS-2 and cyclohexane are the best combination to produce the highest reaction rate among all the catalysts and organic substrates. OMS-2 was also found to be the best catalyst to decompose TBHP. Results show that radicals were partially responsible for the reaction. The reaction pathway in this system was controlled by shape selectivity of OMS-2 catalyst to activation of cyclohexane and to decomposition TBHP (to produce radicals).
Operating system support for server applications (1999)

General-purpose operating systems provide inadequate support for large-scale servers. Server applications lack sufficient control over scheduling and management of machine resources, which makes it difficult to enforce priority policies, and to provide robust and controlled service. For example, server applications cannot provide differentiated quality of service to requests from different clients.\nThe root cause of these problems is a fundamental mismatch between the original design assumptions underlying the resource management mechanisms of current general-purpose operating systems, and the behavior of modern server applications. In particular, the notions of protection domain and resource principal coincide in the process abstraction of current operating systems. Moreover, these operating systems provide insufficient control to an application over the resources that are consumed inside the kernel on behalf of the application. These aspects of current operating systems prevent a server process that manages large numbers of network connections, for example, from properly allocating system resources among those connections.\nThis dissertation addresses the lack of operating system support for fine-grained resource management in large-scale server systems. It starts by characterizing the nature of the mismatch between the design assumptions of current general-purpose operating systems, and the behavior of server applications. The traditional design of core operating system abstractions and APIs is reevaluated in the light of the requirements of server applications. This reevaluation leads to a set of novel operating system abstractions and APIs that serve to provide effective support for server applications.
Interference in Thin Metallic Films (1931)

The phenomenon of the colored appearance of thin metallic films sputtered upon glass or upon other metals, when viewed in white light, is explained as being caused by interference. Some qualitative observations of cyclic changes of color are given which support this viewpoint. Mathematical expressions are derived from Maxwell's electromagnetic equations to express the change of phase as the wave train is reflected from a metal surface in air, from metal in metal, for refraction as the wave enters the metal from air and from air into metal. Use of the values of the indices of refraction and absorption for massive metals indicates fair substantiation of experimental results. Fritze's values of the optical constants for thin metals do not seem to give agreement between theory and experiment. The thickness of the film of copper necessary to produce a yellow color (interference for $\ensuremath{\lambda}=0.48\ensuremath{\mu}$) when calculated from the index of refraction (1.13) is found to be three and one-half times larger than the value found by weighing the total deposit. The balance of evidence seems to support the theory of interference.

Laser Treatment of Retinal Diseases by Subthreshold Laser Effects (1999)

The retinal pigment epithelium (RPE) may play an important role in the therapeutic effect of laser photocoagulation. This suggests a benefit from targeting the RPE instead of the sensory retina. Calculating the actual temperature profile after laser photocoagulation, it can be shown that pulse durations have to be in the order of microseconds (micros) to spare the retina from damage. This is consistent with histological findings after laser exposure with repetitive, 5 micros Nd:YLF laser pulses (527 nm). Therapeutic effects have been shown in patients with diabetic macular edema, drusen, and central serous retinopathy.
IST-TRUST: a perspective on the reconfiguration of future mobile terminals using software download (2002)

The reconfigurable software radio concept has been an active research topic for many years. This was driven initially by military requirements for flexibility, but more recently by the commercial pressure to take advantage of economies of scale, reductions in maintenance costs and more efficient utilisation of spectrum. Therefore, initial projects looking at this concept have focussed on the technology for providing multi-mode and software reconfigurable terminals. The Transparently Reconfigurable Ubiquitous Terminal (TRUST) project differs in that it examines the user requirements in order to identify the frameworks and systems that are needed to support software reconfigurable radios from the users' perspective. The primary goal of the TRUST project is to realise the user potential of reconfigurable radio systems, which will provide network connectivity and services when and where they are required. The project will achieve this through a four-step process: (1) understand the users' requirements from their perspective of the system: "the terminal" (2) translate these users' requirements into technology requirements (3) advance the terminal and network technologies through research and innovation (4) validate, promote and disseminate these advancements and technologies.
