Theoretical Prediction and Measurement of the Fabric Surface Apparent Temperature in a Simulated Man/Fabric/Environment System. (1999)

Abstract : Theoretical analysis is presented to predict the fabric surface apparent temperature in a simulated man/clothing fabric/environment system. The predicted outcomes have been validated by comparison with the experimental results using a sweating hotplate in an environmental chamber. An air gap of approximately 9mm between the fabric and the hotplate surface was found to be the optimum for controlling the fabric surface temperature. The apparent temperature of the fabric can match its surrounding objects by further adjusting its surface emissivity depending on the ambient temperature. A Disruptive Pattern Combat Uniform (DPCU) fabric was used in the experimental assessment of the theoretical predictions which were in good agreement with the theoretical predictions. A sweating hotplate with dry and wet states was also used to assess the influence of evaporative heat on the fabric surface temperature. No significant dffference was found in the fabric surface apparent temperature between the dry and wet states.
iStent trabecular micro-bypass stent for open-angle glaucoma (2014)

Trabecular micro-bypass stents, commonly known as iStents, are micro-invasive glaucoma surgery (MIGS) devices used to treat open-angle glaucoma. Like other MIGS procedures that enhance trabecular outflow, the iStent lowers intraocular pressure (IOP) by creating a direct channel between the anterior chamber and Schlemm's canal. iStents are typically implanted at the time of phacoemulsification for patients with open-angle glaucoma and visually significant cataracts. This review summarizes the published data regarding the efficacy, safety, and cost considerations of trabecular micro-bypass stents. Most studies found statistically significant reductions in mean IOP and ocular medication use after combined phacoemulsification with single or double iStent implantation. The devices were found to be very safe, with a safety profile similar to that of cataract surgery. Complications were infrequent, with the most common complications being temporary stent obstruction or malposition, which resolved with observation or secondary procedures. Future studies are needed to evaluate long-term outcomes, patient satisfaction, cost effectiveness, and expanded indications.
Detecting and exploiting causal relationships in hardware shared-memory multiprocessors (2004)

This thesis focuses on mechanisms that improve inter-processor communi-cation in hardware shared-memory multiprocessors by detecting and exploiting knowledge of the causal relationships among inter-processor reads and writes to shared memory. We present two applications for exploiting causal dependence knowledge: the avoidance of replays in a novel value-based memory ordering mechanism, and the avoidance of coherence misses in an invalidation-based coher-ence protocol. Conventional out-of-order processors employ a multiported, fully-associa-tive load queue to guarantee correct memory reference order both within a single thread of execution and across threads in a multiprocessor system. As improve-ments in process technology and pipelining lead to higher clock frequencies, scal-ing this complex structure to accommodate a larger number of in-flight loads becomes difficult. The value-based memory ordering mechanism presented here solves the associative load queue scalability problem by completely eliminating
High-Fidelity Single-Shot Singlet-Triplet Readout of Precision-Placed Donors in Silicon (2017)

In this work we perform direct single-shot readout of the singlet-triplet states in exchange coupled electrons confined to precision-placed donor atoms in silicon. Our method takes advantage of the large energy splitting given by the Pauli-spin blockaded (2,0) triplet states, from which we can achieve a single-shot readout fidelity of 98.4±0.2%. We measure the triplet-minus relaxation time to be of the order 3 s at 2.5 T and observe its predicted decrease as a function of magnetic field, reaching 0.5 s at 1 T.
Amorphous Cu<sub>2-δ</sub>O as Passivation Layer for Ultra Long Stability of Copper Oxide Nanowires in Photoelectrochemical Environments (2018)

Core-shell CuO-Cu_2O nanowires with a surface amorphous Cu2-δO layer leads to high stability photocathodes for use in photoelectrochemical splitting of water. The nanowires are synthesized via carbothermal reduction of CuO nanowires at 300°C during which a 2–3 nm conformal and amorphous Cu_(2-δ)O layer is formed on the nanowire surface. This Cu_(2-δ)O layer enhances photocurrent and improves photocorrosion stability of the nanowires. While catalyst-free, pristine CuO nanowires show a photocurrent density is 0.50 mA/cm^2 and a stability of 53% after 3.4 hours of testing at −0.50 V under AM1.5 G conditions; the catalyst-free, carbothermally reduced nanowires achieve a photocurrent density of 0.75 mA/cm^2 and an improved stability of 96% under identical test conditions. The mechanism of enhanced photocurrent and its stability is discussed in the context of extensive pre and post test nanowire characterization.
Real time passenger information system for the ROMANSE project (1993)

Extensive use of traveller information systems is proposed in the SCOPE Cities of Southampton, Cologne and Piraeus in order to keep people informed of travel conditions and options and encourage a modal shift from private cars to public transport. The SCOPE concept for integrated urban traffic management combines four main application areas: strategic (or geographic) information systems; dynamic urban traffic control; public transport management; and travel and traffic information. The geographic information systems provide the tools needed for planning and analysis, and a framework in which the other applications can be integrated within a strategy that combines real time and forecast knowledge of the situation on the road and public transport networks. The overall SCOPE concept is illustrated, which shows the components of the Traffic and Traveller, Information Centre (TTIC) being implemented in the ROMANSE project in Southampton.
Unifying Instructional and Game Design (2011)

Games have impacted education, research, and industry in multiple ways, altering notions of interaction. Traditionally, instructional design and educational research have dominated academic studies of pedagogy, teaching, and training. There are many parallels between the fields of game design and education, as both draw inspiration from the study of engagement, interaction, and motivation. State-of-the-art research and trends show great potential to cross-pollinate and uplift each area. This chapter synthesizes instructional and game design concepts based on current research, comparing and contrasting key elements. Towards the goal of providing a road map for readers, the chapter demonstrates three active case studies that illustrate how both fields greatly influence each other, leading to positive outcomes. These cases demonstrate that many concepts in both fields have direct parallels. The chapter concludes with a discussion of potential future directions and trends.
Expression of TIP-1 Confers Radioresistance of Malignant Glioma Cells (2012)

This study provided the first evidence showing that TIP-1 modulates p53 protein stability and is involved in the radioresistance of malignant gliomas, suggesting that antagonizing TIP-1 might be one novel approach to sensitize malignant gliomas to radiotherapy.
The intestinal uptake of particles and the implications for drug and antigen delivery. (1996)

A number of researchers from different scientific disciplines have independently described the uptake of a variety of particulates across the gastrointestinal tract in animal models. The reports of particle uptake are briefly reviewed and the alternative mechanisms and proposed sites of uptake are discussed. Following these observations, some researchers have exploited the phenomenon of particulate uptake by using microparticles and nanoparticles as oral delivery systems for active agents, such as drugs and vaccines. The potential use of particulate carrier systems as drug and vaccine delivery systems is also briefly discussed.
Wear of polymer composites (2002)

The use of polymers and polymer composites in various tribological situations has become state of the art. Nevertheless, new developments are still under way to explore new fields of application for these materials and to tailor their properties for more extreme loading conditions. Some of these developments can be followed when searching through the 56 references given at the end of this review. The present overview describes, in particular, some of the authors' approaches in designing polymeric composites in order to operate under low friction and low wear against steel counterparts. Special emphasis is focused on thermoplastics and thermosets reinforced with special fillers (including nanoparticles). An attempt is made to predict their wear properties and to carry out systematic parameters studies by the use of artificial neural networks. Further information will be given on the fibre orientation dependence of wear of continuous carbon fibre-polymer matrix composites, and on attempts to predict their load-bearing capacity and related wear mechanisms by the use of finite elements. In addition, some new steps towards the development of functionally graded tribomaterials are illustrated.
Heparin modulation of human plasma kallikrein on different substrates and inhibitors (2006)

The interplay of different proteases and glycosaminoglycans is able to modulate the activity of the enzymes and to affect their structures. Human plasma kallikrein (huPK) is a proteolytic enzyme involved in intrinsic blood clotting, the kallikrein-kinin system and fibrinolysis. We investigated the effect of heparin on the action, inhibition and secondary structure of huPK. The catalytic efficiency for the hydrolysis of substrates by huPK was determined by Michaelis-Menten kinetic plots: 5.12x10(4) M-1 s-1 for acetyl-Phe-Arg-p-nitroanilide, 1.40x10(5) M-1 s-1 for H-D-Pro-Phe-Arg-p-nitroanilide, 2.25x10(4) M-1 s-1 for Abz-Gly-Phe-Ser-Pro-Phe-Arg-Ser-Ser-Arg-Gln-EDDnp, 4.24x10(2)M-1 s-1 for factor XII and 5.58x10(2) M-1 s-1 for plasminogen. Heparin reduced the hydrolysis of synthetic substrates (by 2.0-fold), but enhanced factor XII and plasminogen hydrolysis (7.7- and 1.4-fold, respectively). The second-order rate constants for inhibition of huPK by antithrombin and C1-inhibitor were 2.40x10(2) M-1 s-1 and 1.70x10(4) M-1 s-1, respectively. Heparin improved the inhibition of huPK by these inhibitors (3.4- and 1.4-fold). Despite the fact that huPK was able to bind to a heparin-Sepharose matrix, its secondary structure was not modified by heparin, as monitored by circular dichroism. These actions may have a function in the control or maintenance of some pathophysiological processes in which huPK participates.
A new diagnostic for cancer dynamics: status and initial tests of the NANIVID (2009)

The Tumor MicroEnvironment for Metastasis (TMEM) is a critical determinant which will presage the evolution of
primary tumors and the resulting metastatic dynamics. Primary tumor cells up and down regulate certain genes which
increase motility and cause a disregard for positional information. We report on the development of a new tool for the
documentation of cancer cell migration (initial targets: the rat mammary adenocarcinoma cell lines MTLn3 with an over
expression of Mena+++). This tool, the NANo IntraVital Device (NANIVID), is a multi-functional nanosystem
composed of a chemoattractant source (hydrogel-EGF), capsule (cell trap), counter (transparent, interdigitated electrode
arrays for sensing cell arrival), and remote reporter (readout electronics). The device will be retrieved from the tumor
site and the cells will be expelled for subsequent assay. The NANIVID will be used in conjunction with the current
catheter-based approach in which a needle is loaded with a chemoattractant source and injected into the tumor. A major
drawback in the catheter approach is the short cell collection time and lack of real time registering and reporting of cell
arrival. This paper will present the current status of the NANIVID prototypes developed in which a transparent
implantable device is loaded with chemoattractant source and placed near candidate mammary gland tumors in an
established rat model for multiple days or weeks. This series of experiments will allow the comparison of methods and
to benchmark the NANIVID for use in research. Initial results of these experiments and NANIVID design modifications
will be presented.

An investigation of the lattice and interlayer water vibrational spectral regions of muscovite and vermiculite using Raman microscopy. A Raman microscopic study of layer silicates (1982)

Abstract The micro Raman spectrum of ∼100fg of the clay materials Muscovite and Vermiculite in the region of 600 cm −1 −3300 cm −1 is reported. An attempt has been made to assign the observed Raman shifts in particular those of H‐bonded OH − , which may have significance to an understanding of the role which clay plays in the absorption of soil water.
Numerical Studies of Left Handed Metamaterials (2002)

We use the three dimensional Finite Difference Time Domain (FDTD) technique to study metamaterials exhibiting both negative permittivity and permeability in certain frequency bands. The structure under study is the well-known periodic arrangement of rods and split-ring resonators, previously used in experimental setups. The three parameters we study are the transmission coefficient of a slab, the phase variation of the propagating fields within the metamaterial, and the refraction of a wave through a prism. To our knowledge, this is the first time that the last two parameters are studied rigorously using a numerical method. The results of this work show that fields propagating inside the metamaterial with a forward power direction exhibit a backward phase velocity and negative index of refraction.
Transient shear stresses on a suspension cell in turbulence (1990)

A model flow field representative of Kolmogorov eddies in turbulence is proposed, and its two parameters are expressed in terms of the known bioreactor variables epsilon, the rate of turbulent power dissipation, and nu, the fluid kinematic viscosity. The trajectory through this flow field of a small sphere representing a cell is determined, and from that the time-varying local shear rate can be found. This allows calculation of the shear stress at any point on the sphere's surface as it rotates in and moves through the model eddy. The maximum shear stress imposed on the cell by the surrounding turbulence has a range of 0.5-5 dyn/cm(2), and can be estimated by 5.33rho(epsilonnu)(1/2). The shear stress has two major frequency components with ranges of 1-4 and 20-80 s(-1); the higher frequency component is estimated by 0.678(epsilon/nu)(1/2). The rotation of the direction of the shear stress vector at each point on the cell's surface is also discussed. Two ways in which external stresses might affect cell growth are proposed.
High Prevalence of Antibodies to the gp120 V3 Region Principal Neutralizing Determinant of HIV-1 <sub>MN</sub> in Sera from Africa and the Americas (1991)

Neutralizing antibodies (NA) against HIV-1MN and HIV-1IIIB, and antibodies binding to synthetic peptides (BA) derived from the gp120 envelope V3 region principal neutralizing determinants (PND) of the HIV-1MN, HIV-1IIIB, and HIV-1Z3 virus strains were assayed in HIV-1 antibody-positive sera from the United States, Haiti, Brazil, Zaire, and Zimbabwe. The ability of soluble PND peptide to block neutralization of the corresponding virus by representative sera was also tested. In each country, NA and BA titers were highest against the HIV-1MN strain, and compared with other countries, NA and BA titers against HIV-1MN were higher in sera from the United States and Haiti. When NA titers were compared with BA titers against either HIV-1MN or HIV-1IIIB, no correlation was found for the HIV-1IIIB strain, but there was a significant correlation for HIV-1MN. Addition of the HIV-1MN strain peptide to a neutralization assay for HIV-1MN resulted in a four- to tenfold reduction in NA titers in sera from the United States, Zaire, and Brazil. The results suggest that HIV-1MN and closely related variants are prevalent in many parts of the world, and that antibodies directed against the PND account for most of the neutralizing activity in sera of infected individuals.
Spectrum Shaping with Parity Sequences (1972)

For certain types of digitally generated holographic memories, it is important that the Fourier components to be stored have a constant, or nearly constant, modulus. It is shown that by interlacing two sequences of complex numbers, one a data sequence representing the information to be stored and the second a parity sequence, derivable from the data sequence, the discrete Fourier transform of the combined sequence can be made to have a constant modulus. A slight variation of the method leads to a spectrum with varying modulus but only a discrete set of phases. The sequences may be one-dimensional or multidimensional.
Lack of Pain Reduction by a Vibrating Local Anesthetic Attachment: A Pilot Study (2005)

A vibrating dental local anesthesia attachment (Vibraject, LLC, Calif) based on the concept of the gate-control theory has been used in clinical practice. The theoretical advantage of the vibrating needle is that it reduces the injection pain. We evaluated the effectiveness of Vibraject in combination with an electrical injection device. Injections were given into the alveolar mucosa adjacent to the root apex of the maxillary lateral incisor in 10 volunteers. Vibraject was randomly applied to either the left or right side of the injection. No statistically significant decrease in pain scores was found at needle insertion or anesthetic injection. The clinical efficacy of Vibraject remains controversial.
Distal Myopathy (1990)

Various types of the distal myopathy except Welander's late distal myopathy of Swedish type were described. There were many reports in the past concerning the varieties of the distal myopathy. Distal myopathy is a rather rare disorder and it may be difficult to diagnose these cases. Among these various distal myopathy, an emphasis was made upon the clinical and pathological characteristics of the diseases, particularly distal muscular dystrophy of Miyoshi, Distal myopathy with rimmed vacuole formation of Nonaka and ours, and Oculo-pharyngo-distal myopathy. All these diseases show the distal muscle involvement but the clinical features, heredity, course and pathological features are quite different, and prognosis is also different. Accordingly when we examined these distal myopathy cases, clinical characteristics and histo-pathological findings should be carefully studied. It should be also emphasized that the level of serum CPK dose not indicate the severity of the myopathy. In muscular dystrophy or myositis, serUm CPK elevates remarkably and we can consider the level of CPK as a sign of the severity or condition of the disease. However, in myopathy as "rimmed vacuole distal myopathy" serum CPK remains in normal level even though weakness is severe. This is due to absence of the membrane abnormalities of muscle cells. Leakage of the CPK from muscle cells, therefore, does not reflect the degree of the cell destruction. In this point we have to remember the fact that serum CPK is not a indicator of all muscle diseases and even if the CPK is normal, we have to consider the presence of myopathy.
Protein Malnutrition in the Domestic Fowl Induces Alterations in Adrenocortical Function* (1988)

Adrenocortical function was investigated in immature, dietary protein-restricted domestic fowl (Gallus gallus domesticus). White Leghorn cockerels (2 weeks old) were fed isocaloric semipurified diets containing either 8% [low (L)] or 20% [normal (N)] soy protein for 4 weeks ad libitum. Cockerels were quickly killed by decapitation and exsanguination. Trunk plasma corticosterone (B) and ACTH levels were measured by RIA. Maximal B-binding capacity (CBC) of plasma was also measured. In addition, in randomly selected cockerels, a rough index of the B clearance rate was determined. Finally, to determine the influence of protein malnutrition on adrenocortical cell function per se, we measured the acute (2-h) B responses of highly enriched adrenocortical cell populations to various ACTH analogs, 8-bromo-cAMP (8-Br-cAMP), and cellular B production maximally supported with 25-hydroxycholesterol. Plasma B and ACTH concentrations of L cockerels were, respectively, 160% greater and 32% less than those of N cockerels. In addition, plasma B clearance rate of L birds was 85% greater than that of N birds, thus suggesting a greater B secretion rate in L birds. However, maximal plasma CBC of L cockerels was 59% less than that of N cockerels. Thus, the free plasma B concentration of L birds was greater than that of N birds. The increase in the plasma B concentration of L cockerels is explained in part by the relative adrenal weight of these birds which was 88% greater than that of N cockerels. In addition, there were differences at the adrenocortical cell level. On an equal cell concentration basis, basal and maximal B production values (stimulated by ACTH analogs and 8-Br-cAMP, and supported by 25-hydroxycholesterol) of L cockerel adrenocortical cells were, respectively, 73% and 139% greater than those of N cockerel adrenocortical cells. In addition, maximal ACTH-induced aldosterone production of L bird cells was 104% greater than that of N bird cells, such that the ratio of aldosterone production to B production was not altered by protein deprivation. The data suggest that the greater steroidogenic capacity of L cockerel cells was due to an increase in intracellular steroidogenic enzyme content and/or activity and not to an alteration in the composition of adrenocortical cell types within the populations of isolated cells. Furthermore, ACTH analog ED50 values for B, aldosterone, and cAMP production by L bird cells were about one third to one fifth the values for N bird cells, thus indicating that L bird cells were about 3-5 times more sensitive to ACTH than were N bird cells.(ABSTRACT TRUNCATED AT 400 WORDS)
