Investigation into MU-MISO transmission with limited feedback (2006)

Downlink multiuser transmission techniques that can serve several users simultaneously in frequency and time have been recently recognized as a promising means to significantly increase system capacity. A disadvantage of these techniques is that accurate channel state information at the transmitter (CSIT) is essential for their proper operation. In practice however perfect CSIT is hard to obtain. In this paper multi-user multiple-input single-output (MU-MISO) transmission with limited feedback is investigated. In particular two feedback design strategies are introduced. One allows users to cooperate in the sense that they can do feedback jointly, which is unrealistic but may serve as an upper-bound of achievable performance of a realistic system. The other is non-cooperative where each user feeds back its CSI in an independent manner. Simulation results show that multi-user transmission needs much more accurate CSI to perform well compared to single-user transmission even when cooperation between users is allowed
Improved fabrication of melt electrospun tissue engineering scaffolds using direct writing and advanced electric field control (2015)

Direct writing melt electrospinning is an additive manufacturing technique capable of the layer-by-layer fabrication of highly ordered 3d tissue engineering scaffolds from micron-diameter fibres. The utility of these scaffolds, however, is limited by the maximum achievable height of controlled fibre deposition, beyond which the structure becomes increasingly disordered. A source of this disorder is charge build-up on the deposited polymer producing unwanted coulombic forces. In this study we introduce a novel melt electrospinning platform with dual voltage power supplies to reduce undesirable charge effects and improve fibre deposition control. We produced and characterised several 90° cross-hatched fibre scaffolds using a range of needle/collector plate voltages. Fibre thickness was found to be sensitive only to overall potential and invariant to specific tip/collector voltage. We also produced ordered scaffolds up to 200 layers thick (fibre spacing 1 mm, diameter 40 μm) and characterised structure in terms of three distinct zones; ordered, semi-ordered and disordered. Our in vitro analysis indicates successful cell attachment and distribution throughout the scaffolds, with little evidence of cell death after seven days. This study demonstrates the importance of electrostatic control for reducing destabilising polymer charge effects and enabling the fabrication of morphologically suitable scaffolds for tissue engineering.
National Training Organisations: their contribution to waste minimisation in the UK (2001)

National Training Organisations (NTOs) were introduced in 1998 as a method of increasing competitiveness by raising standards in education and training. By offering training at a variety of NVQ classifications targeting all involved in the business operation, they are ideally placed to deliver the Government's objectives of lifelong learning, set out in the Green Paper, 'The Learning Age'. However, business growth needs to occur in line with increasing environmental legislation, in response to the UK's commitment to the concept of sustainable development. As waste minimisation is a key component of sustainable development, acknowledged in the Waste Strategy 2000, it is important that NTOs raise the awareness of this issue and the potential savings that are available to their network of organisations. As a result of a confidential questionnaire sent to 65 NTOs, it is clear that most do not yet recognise the importance of developing waste minimisation practice within their sectors. It seems unlikely that NTOs can succeed in increasing sustainable competitiveness if they do not seek to introduce practices that reflect present environmental policy. NTOs need to ensure that senior management understand that environmental issues are not opposed to commercial success, but rather a tool which can drive competitiveness by limiting waste, conserving resources and lowering costs.
RETRO-BULBAR NEURITIS: (Five Cases) due to Para-nasal Sinusitis (1944)

RETRO-BULBAR NEURITISCases of mucocele in Nigerians have been seen by the writer in connection with ethmoidal cells and the frontal sinus.As no case of this type has been seen, it may prove of interest."In Diseases of the Nose, Throat and Ear," by A. Logan Tnrner, Ed., 1936, the following statement appears on page 96."It is doubtful if a parallel condition (i.e., mucocele), has been found in the antrum."The swelling in this case was situated just above the lower margin of the orbit, and could be palpated for a certain distance into the orbit.ft gave the typical sensation of a fluid- containing cyst, and was but slightly inoveable from side ta side.The globe was displaced upwards.Apart from disfigurement and diplopia the patient suffered little inconvenience.His photograph belies his mental outlook-he was not worried; he had no pain; it is unlikely for those reasons that he will trouble to come the 15 miles or so to hospital.It is regretted thFt definite proof that this is a mucocele of the antrum has not, so far, been obtained in this case.RETRO-BULBAR NEURITIS (Five Cases) due to Para-nasal Sinusitis BY ROSA FORD LONDON WE see many eyes that are quite normal; with poor, sometimes extremely defective, sight.If this blindness is in only one eye, or in both with no hemianopia, the lesion must lie in one or both optic nerves, and the condition is called retro-bulbar neuritis.

Efficient high-gain laser amplification from a low-gain amplifier by use of self-imaging multipass geometry (2001)

We characterize a self-imaging multipass amplifier scheme that provides both high extraction efficiency and overall gain. A diode-pumped slab amplifier with a single-pass small-signal gain of 2.5 is used in a 16-pass mode to amplify an input pulse from 50 muJ to 50 mJ, extracting approximately 22% of the stored energy. A stimulated Brillouin-scattering phase-conjugate mirror provides isolation from amplified spontaneous emission, prevents gain depletion, and also ensures good beam quality. The system can be operated from 10 Hz to in excess of 450 Hz, with modest changes in the beam quality and energy. The scheme has the potential to be scaled to higher-energy and higher-power systems.
Robot-assisted shape deposition manufacturing (2002)

Solid freeform fabrication and shape deposition are rapid manufacturing processes which build parts by incremental material deposition and fusion of cross-sectional layers. In this paper, several thermal deposition processes are described for directly fabricating prototype metal shapes using robotically manipulated material deposition systems. A robotic palletizing/part transfer system is also described which integrates multiple deposition and shaping processes into a single facility for rapidly manufacturing functional shapes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Induction of delayed follicular rupture in the human by the selective COX-2 inhibitor rofecoxib: a randomized double-blind study (2001)

This study suggests that selective COX-2 inhibition has a negative, local effect on human ovulation, resulting in delayed follicular rupture, without affecting peripheral hormonal cyclicity.
A randomized controlled trial of intranasal ketamine in migraine with prolonged aura (2013)

This study provides class III evidence that intranasal ketamine is effective in reducing aura severity in patients with migraine with prolonged aura.
Detection of Neonatal Carnitine Palmitoyltransferase II Deficiency by Expanded Newborn Screening With Tandem Mass Spectrometry (2001)

The introduction of tandem mass spectrometry to newborn screening has substantially expanded our ability to diagnose metabolic diseases in the newborn period. We report the first case of neonatal carnitine palmitoyltransferase deficiency II detected by expanded newborn screening with tandem mass spectrometry. The neonate presented with dysmorphic facial features, structural malformations, renal failure, seizures, and cardiac arrythmias and died on the third day of life. This experience illustrates the importance of expanded newborn screening to avoid missing a metabolic diagnosis in early infantile death.
Synthesis of 4-Quinolones via a Carbonylative Sonogashira Cross-Coupling Using Molybdenum Hexacarbonyl as a CO Source (2015)

A palladium-catalyzed CO gas-free carbonylative Sonogashira/cyclization sequence for the preparation of functionalized 4-quinolones from 2-iodoanilines and alkynes via two different protocols is described. The first method (A) yields the cyclized products after only 20 min of microwave (MW) heating at 120 °C. The second method (B) is a gas-free one-pot two-step sequence which runs at room temperature, allowing the use of sensitive substituents (e.g., nitro and bromide groups). For both protocols, molybdenum hexacarbonyl was used as a solid source of CO.
The role of cryptography in database security (2004)

In traditional database security research, the database is usually assumed to be trustworthy. Under this assumption, the goal is to achieve security against external attacks (e.g. from hackers) and possibly also against users trying to obtain information beyond their privileges, for instance by some type of statistical inference. However, for many database applications such as health information systems there exist conflicting interests of the database owner and the users or organizations interacting with the database, and also between the users. Therefore the database cannot necessarily be assumed to be fully trusted.In this extended abstract we address the problem of defining and achieving security in a context where the database is not fully trusted, i.e., when the users must be protected against a potentially malicious database. Moreover, we address the problem of the secure aggregation of databases owned by mutually mistrusting organisations, for example by competing companies.
The <i>Legionella</i> IcmS–IcmW protein complex is important for Dot/Icm‐mediated protein translocation (2004)

The intracellular pathogen Legionella pneumophila can infect and replicate within macrophages of a human host. To establish infection, Legionella require the Dot/Icm secretion system to inject protein substrates directly into the host cell cytoplasm. The mechanism by which substrate proteins are engaged and translocated by the Dot/Icm system is not well understood. Here we show that two cytosolic components of the Dot/Icm secretion machinery, the proteins IcmS and IcmW, play an important role in substrate translocation. Biochemical analysis indicates that IcmS and IcmW form a stable protein complex. In Legionella, the IcmW protein is rapidly degraded in the absence of the IcmS protein. Substrate proteins translocated into mammalian host cells by the Dot/Icm system were identified using the IcmW protein as bait in a yeast two-hybrid screen. It was determined that the IcmS-IcmW complex interacts with these substrates and plays an important role in translocation of these proteins into mammalian cells. These data are consistent with the IcmS-IcmW complex being involved in the recognition and Dot/Icm-dependent translocation of substrate proteins during Legionella infection of host cells.
Gain Scheduled $H_{\infty}$ Control for Air Path Systems of Diesel Engines Using LPV Techniques (2007)

This paper addresses the modeling and control of the air path system of diesel engines. The underlying issues are critical for the control of the transient exhaust gas fraction pumped into the cylinders, which is known to be a dominant factor to reduce the nitrogen oxides (NO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> ) emissions. In this paper, we propose a new approach, based on a data-based grey-box linear parameter varying (LPV) model as well as on the gain scheduled H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">infin</sub> technique for the controller design. The modeling step is shown to lead naturally to a so-called quasi-LPV structure, which also delivers the scheduling variables to be accounted for. Using this information, gain scheduled H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">infin</sub> techniques allow to design a controller which enforces a much better tracking performance than the standard production electronic control unit, while not requiring any calibration work. The performance of the proposed approach is demonstrated by experimental results
Consideration of the mechanism of styrene/ethylene copolymerization with half‐titanocene catalysts (2005)

Abstract Styrene/ethylene copolymerization was performed by Longo et al. with the use of a cyclopentadienyltitanium trichloride (CpTiCl 3 )/methylaluminoxane (MAO) system with various aluminum/titanium ratios and various monomer compositions. The obtained polymer consisted of a mixture of an ethylene–styrene pseudorandom copolymer, polyethylene, and poly(styrene‐ block ‐ethylene) with a syndiospecific styrene–styrene unit (SPS‐ b ‐PE). In this work, from the whole polymer obtained with the CpTiCl 3 /MAO catalyst system, the SPS‐ b ‐PE copolymer was separated with the temperature rising elution fractionation method, and the structure was specified by 13 C NMR. The polymer obtained from the trivalent titanium catalyst, which was thought to be the active species of syndiotactic polystyrene, included both a styrene–styrene sequence and a styrene–ethylene–ethylene–styrene sequence. However, neither the styrene–ethylene–styrene sequence nor the long chain of polyethylene was included. © 2005 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 43: 5041–5048, 2005
Design and modeling of tapered LWL architecture for high density SRAM (2004)

Evaluation of oestrogen and progesterone receptor expression in uterine mucosal lymphocytes (1996)

Expression of the oestrogen and progesterone receptors on uterine mucosal leukocytes has been examined by dual immunohistology. Neither the oestrogen receptor nor the progesterone receptor was expressed by lymphocytes, macrophages or the distinctive population of uterine natural killer (NK) cells. Although the accumulation and survival of these NK cells appears to be hormonally dependent, the effects must therefore be indirect.
Antibody spectrum against the viral transactivator protein in patients with human immunodeficiency virus type 1 infection and Kaposi's sarcoma. (2000)

We analyzed patterns of antibody response to recombinant transactivator protein (human Immunodeficiency virus type 1 [HIV-1] tat) in serum samples from HIV-1-negative subjects (n = 60), HIV-1-infected asymptomatic patients (n = 20), HIV-1-infected patients with Kaposi's sarcoma (n = 25), and patients with Kaposi's sarcoma without HIV-1 infection. None of the healthy subjects possessed anti-tat immunoglobulin G (IgG) in their serum. All asymptomatic patients with HIV-1 infection were anti-tat IgG-positive. Epitope mapping revealed that these sera had anti-tat IgG to all the functional domains of tat protein. Histochemical studies on lymph nodes from five asymptomatic HIV-1-infected patients showed that, in all cases, tat-positive cells were present within the germinal center at the stage of follicular fragmentation containing immunoblasts and small lymphocytes. Of the 25 HIV-1-infected patients with Kaposi's sarcoma, 4 were anti-tat IgG-positive; however, the epitope analysis revealed that IgG to functional domains of tat protein--in particular to transactivating response element (TAR)-binding site--were absent. All patients with Kaposi's sarcoma without HIV-1 infection were anti-tat IgG-negative. Presence or absence of anti-tat IgG and a prevalence of different antibody profiles in different groups of patients indicated the pathophysiologic role of tat protein. Thus, a passive immunization with anti-tat IgG could be a useful strategy to influence the pathophysiologic state of the disease.
A Cleavage Map of Bacteriophage ϕX174 Genome (1974)

Restriction endonucleases isolated from Hemophilus influenzae, Hemophilus parainfluenzae, and Hemophilus aegyptius were used to cleave varphiX174 replicative form DNA into three sets of specific DNA fragments. The order of these fragments in the varphiX replicative form molecule was determined by (1) analysis of partial digest products, (2) analysis of overlapping sets of fragments produced by two different restrictive enzymes. On the basis of these results, a detailed physical map of the varphiX174 genome has been constructed with respect to the cleavage sites of all three enzymes.
Direct coloration of textiles with photochromic dyes. Part 3: dyeing of wool with photochromic acid dyes (2012)

Wool dyed with two isomeric water‐soluble spirooxazine‐based photochromic acid dyes, which were specifically designed and synthesised for direct application to protein and polyamide substrates, showed reversible change from a pale yellowish colour to blue when exposed to sunlight or UV light. With the first dye, significantly higher photochromic colour change was obtained when the wool was bleached, a feature attributed to a more open fibre structure which may facilitate penetration of the non‐planar dye anion and also the photocoloration reaction which requires a change in molecular geometry. Experimentation demonstrated that the optimum conditions for application of this dye to wool was from an aqueous dyebath at neutral pH and a temperature of 60 °C. An investigation using HPLC demonstrated that the dye was susceptible to decomposition in aqueous solution at higher temperatures and at lower pH values. The second dye was also applied to wool fabric to give a fabric with similar photochromic properties. The technical performance of the dyed fabrics, in terms of washfastness and photostability, was assessed.
Bacterial Streak and Bulb Rot of Sweet Onion: II. Epiphytic Survival of <i>Pseudomonas viridiflava</i> in Association with Multiple Weed Hosts (1998)

A semiselective agar medium (T-5) was used to sample environment and plant material as a habitat for Pseudomonas viridiflava. Soil, irrigation water, soybean foliage, and foliage from various weeds in an onion-growing area were assayed over a 5-year period. P. viridiflava was recovered only as an epiphytic resident from weed species that included cutleaf evening primrose, dandelion, common fumitory, purple cudweed, spiny sowthistle, Virginia pepperweed, and wild radish. The bacterium apparently overseasons in association with these weeds, because its presence was detected prior to, as well as during, the onion-growing season. Preliminary tests indicated that weed control may suppress bacterial streak and bulb rot levels.

How feasible is the reuse of grammars for Named Entity Recognition (2002)

In this paper, we investigate whether reusing existing grammars for NE recognition instead of creating them from scratch is a viable solution to time constraints in developing grammars. We discuss three possible factors that hinder grammar reuse and we present our corresponding empirical results, that encourage more widespread use of valuable existing resources. 1.
Cryolipolysis for safe and effective inner thigh fat reduction (2015)

The CoolFit flat cup vacuum applicator was found to deliver safe and effective cryolipolysis treatment to reduce inner thigh fat. Completed 16-week data from 42 subjects show 2.8 mm reduction in fat thickness and 0.9 cm reduction in circumference. Assessment of clinical photographs found 91% correct identification of baseline images. The results of this prospective, multi-center, interventional clinical study contributed to FDA clearance of cryolipolysis for treatment of thighs in April 2014.
Activation of the Erk mitogen-activated protein kinase pathway stimulates neuroendocrine differentiation in LNCaP cells independently of cell cycle withdrawal and STAT3 phosphorylation. (2002)

Neuroendocrine (NE) differentiation in prostate cancer (PCa) has been found in some studies to correlate with unfavorable clinical outcome. The mechanisms by which PCa acquires NE properties are poorly understood. In this study, we demonstrate that heparin-binding epidermal growth factor-like growth factor (HB-EGF), a prostate smooth muscle-derived mitogen and survival factor, can evoke NE differentiation in LNCaP human PCa cells. HB-EGF induction of NE differentiation was mediated by a mitogen-activated protein kinase (MAPK) kinase-dependent mechanism, and this process was blocked by p38 MAPK signaling. NE differentiation induced by HB-EGF occurred independently of STAT3 phosphorylation and coincided with continued cell cycle transit. These findings suggest that endogenous stroma-derived factors, acting through MAPK signaling pathways, may play a significant role in the acquisition of NE properties by PCa cells. They also demonstrate that withdrawal from the cell cycle is not a prerequisite for expression of NE characteristics by PCa.
Analysis of Multilayered Microelectronic Packaging Under Thermal Gradient Loading (2006)

An accurate estimation of interfacial and axial stresses in multilayered structures is important in the design process of microelectronic packaging because these stresses drive the failure modes in the package. During manufacturing, microelectronic packaging devices usually suffer from severe thermal gradients. Design engineers often simplify the thermal gradient case as an isothermal loading case by averaging the temperature of the top and bottom of the microelectronic packaging device. Such simplification usually underestimates the stress level in the devices. With the analytical model presented in this paper, the stresses in multilayered microelectronic packaging devices subjected to thermal gradient loading can easily be predicted. It is shown that ignoring the thermal gradient in the package leads to underestimation of stresses
