Neonatal head and torso vibration exposure during inter-hospital transfer (2017)

Inter-hospital transport of premature infants is increasingly common, given the centralisation of neonatal intensive care. However, it is known to be associated with anomalously increased morbidity, most notably brain injury, and with increased mortality from multifactorial causes. Surprisingly, there have been relatively few previous studies investigating the levels of mechanical shock and vibration hazard present during this vehicular transport pathway. Using a custom inertial datalogger, and analysis software, we quantify vibration and linear head acceleration. Mounting multiple inertial sensing units on the forehead and torso of neonatal patients and a preterm manikin, and on the chassis of transport incubators over the duration of inter-site transfers, we find that the resonant frequency of the mattress and harness system currently used to secure neonates inside incubators is [Formula: see text]. This couples to vehicle chassis vibration, increasing vibration exposure to the neonate. The vibration exposure per journey (A(8) using the ISO 2631 standard) was at least 20% of the action point value of current European Union regulations over all 12 neonatal transports studied, reaching 70% in two cases. Direct injury risk from linear head acceleration (HIC<sub>15</sub>) was negligible. Although the overall hazard was similar, vibration isolation differed substantially between sponge and air mattresses, with a manikin. Using a Global Positioning System datalogger alongside inertial sensors, vibration increased with vehicle speed only above 60 km/h. These preliminary findings suggest there is scope to engineer better systems for transferring sick infants, thus potentially improving their outcomes.

Metal-insulator-metal tunnel junctions (MIMTJs) have become a fundamental enabling technology for microelectronics, and obtaining a well controlled, atomically thin, high-quality insulating tunnel barrier is key to their progress. Through experiment and simulations, the authors establish an atomic-layer deposition process to make ultrathin Al${}_{2}$O${}_{3}$ barriers of superior quality to industry-standard AlO${}_{x}$. Their method can improve magnetic tunnel junctions or Josephson junctions, for example, and thus a host of applications.
Analyses of HLA-C–specific KIR repertoires in donors with group A and B haplotypes suggest a ligand-instructed model of NK cell receptor acquisition (2010)

To determine the influence of KIR and HLA class I polymorphism on human NK cell repertoires, 32 different clonotypes representing all possible combinations of 4 inhibitory KIR and NKG2A were analyzed by multicolor flow cytometry. In donors homozygous for the common group A KIR haplotype, a significant influence of HLA-C ligands was seen: KIR repertoires were dominated by clonotypes expressing a single KIR for the respective cognate ligand, either the C1-specific KIR2DL3 or C2-specific KIR2DL1. In contrast, in donors possessing the polymorphic group B haplotypes, a similar adaptation to cognate HLA-C was lacking. We suggest that this discrepancy is largely the result of a suppressive effect of the group B-specific KIR2DL2 on the frequency of KIR2DL1(+) NK cells. In functional assays, KIR2DL2 not only recognized C1 but also C2 ligands, showing overlapping specificity with KIR2DL1. Moreover, using an NK cell differentiation assay we show sequential acquisition of KIR2DL2 before KIR2DL1 on developing NK cells. Together, these observations are compatible with a ligand-instructed model of NK cell education, in which recognition of HLA class I by an inhibitory receptor (KIR2DL2) suppresses subsequent expression of a second receptor (KIR2DL1) of related specificity. Importantly, the ligand-instructed model fits to the observed KIR repertoires in both broad KIR haplotype groups.

Mapping Multidimensional Space to One Dimension for Computer Output Display (1968)

Abstract—The problem considered is the mapping of a functional's multidimensional bounded domain onto a bounded interval of the real line. This transformation is to have the property that "neighboring" points in the bounded interval are necessarily mapped from "neighboring" points in the bounded domain. The multidimensional bounded domain is partitioned into a finite number of elementary regions while the bounded interval is partitioned into the same finite number of elementary intervals. A one-to-one correspondence is defined between the elementary regions and intervals such that neighboring elementary intervals have corresponding multidimensional elementary regions that are neighboring. The degree of neighborliness is controlled by controlling the fineness of partitioning. By suitably defining an equivalent function over the bounded interval, properties of the original functional can be displayed.
Pervaporation separation of binary organic‐aqueous liquid mixtures using crosslinked PVA membranes. I. Characterization of the reaction between PVA and PAA (1993)

Abstract For the purposes of the water‐selective membrane material development for pervaporation separation, poly(vinyl alcohol) (PVA) was crosslinked with a low molecular weight of poly(acrylic acid) (PAA). The crosslinking reactions between PVA and PAA were characterized through IR spectroscopy, differential scanning calorimetry (DSC), and tensile tests when varying the reactions conditions, that is, time, temperature, amounts of cross‐linking agents, PAA. It was found that the crosslinking reaction was fast: in other words, that the reaction mainly occurred at the initial step of each reaction condition. The best reaction conditions for preparing the crosslinked PVA membranes were found to be: reaction time not over 1 h, reaction temperature in the range of 150–180°C. PAA contents of 15–20 wt % were found satisfactory with respect to the application areas. © 1993 John Wiley & Sons, Inc.
<title>Magnetically actuated metallic microgripper</title> (1998)

The design and the fabrication of a magnetically actuated microgripper are described. The device is designed to have an out-of-plane motion; a novel concept among the microfabricated grippers. The gripper consists of three metallic fingers, radially directed and equally spaced on a circle; each finger composed by two beams, whose motion is driven by a magnetic field. The microgripper is modeled as an elastic system of two rectilinear beams, using Euler- Bernoulli theory for small deflections. The boundary value problem is solved and the deflection of the structure is calculated as a function of the magnetic force. The microgripper is fabricated using a UV-lithography based 3D electroforming technique. Each layer of the structure is made by metal electrodeposition into a polyimide mold. Several layers are stacked by repeated deposition and the final structure is obtained by dissolving the mold. Details about the fabrication techniques are presented and discussed. Properties and problems related to the photosensitive polyimide used (such as moisture absorption, loss of adhesion, etc.) are addressed. Electroforming of nickel, copper and permalloy are performed and optimized. In particular, a nickel activating solution is applied successfully for electroforming of microstructures. A shadow mask technique for seed-layer patterning is presented and discussed. A planar electromagnetic coil is fabricated by micromolding of thick photoresist and copper electroforming into the mold. The magnetic circuit is made by electrodeposition of permalloy.

Improved consistency model in cloud computing databases (2014)

Nowadays cloud computing is the fastest growing technology that is used as a source of providing service through Internet. It is an enhanced model of Utility Computing. It embodies all technologies in Computer Architecture. It delivers the clients the needed applications, processes and Information as a service. It provides software platform as a service and virtualized servers, storage area and networks as a service. In addition to that it also manages and delivers database services. The traditional time consuming way of database management degrades the system performance. At present a weak form of consistency is maintained in cloud computing environment. This paper introduces an improved consistency model for cloud computing platform using prioritized read-write mechanism.
Thrust Measurement of Dielectric Barrier Discharge Plasma Actuators and Power Requirements for Aerodynamic Control (2010)

Plasma-based aerodynamic actuators can modify a flow field without the need for moving control surfaces or a source of pressurized air. Actuator power consumption and thrust production were measured for driving frequencies between 1 and 18 kHz, and for driving voltages of 6 and 9 kV peak to peak. The actuator consumed between 3 and 22 W, and produced thrust levels between 0.05 and 0.2 mN per meter span. A comparison of results showed good agreement between this work and previous authors’ results. The actuator effectiveness (thrust produced per watt of power input) was found to range between 0.017 and 0.11 mN/W. The continuous power consumption of a DBD actuator-based control system was then estimated by modeling the actuators as jet flaps. The elevator jet flap strength required to trim a small aircraft in flight was determined. A 0.5 kg aircraft with 0.76 m 2 wing area required between 0.47 and 2.22 kW of power for trim. A 3 kg aircraft with 1.27 m 2 wing area required between 13.6 and 54.6 kW of power for trim. In the most challenging circumstances, flight at stall or max velocity, current battery capacities would allow these aircraft to maintain trimmed flight for only 73 seconds.
Albumin contributes to kidney disease progression in Alport syndrome (2016)

Alport syndrome is a familial kidney disease caused by defects in the collagen type IV network of the glomerular basement membrane. Lack of collagen-α3α4α5(IV) changes the glomerular basement membrane morphologically and functionally, rendering it leaky to albumin and other plasma proteins. Filtered albumin has been suggested to be a cause of the glomerular and tubular injuries observed at advanced stages of Alport syndrome. To directly investigate the role that albumin plays in the progression of disease in Alport syndrome, we generated albumin knockout (Alb(-/-)) mice to use as a tool for removing albuminuria as a component of kidney disease. Mice lacking albumin were healthy and indistinguishable from control littermates, although they developed hypertriglyceridemia. Dyslipidemia was observed in Alb(+/-) mice, which displayed half the normal plasma albumin concentration. Alb mutant mice were bred to collagen-α3(IV) knockout (Col4a3(-/-)) mice, which are a model for human Alport syndrome. Lack of circulating and filtered albumin in Col4a3(-/-);Alb(-/-) mice resulted in dramatically improved kidney disease outcomes, as these mice lived 64% longer than did Col4a3(-/-);Alb(+/+) and Col4a3(-/-);Alb(+/-) mice, despite similar blood pressures and serum triglyceride levels. Further investigations showed that the absence of albumin correlated with reduced transforming growth factor-β1 signaling as well as reduced tubulointerstitial, glomerular, and podocyte pathology. We conclude that filtered albumin is injurious to kidney cells in Alport syndrome and perhaps in other proteinuric kidney diseases, including diabetic nephropathy.
A game recommender system using collaborative filtering (GAMBIT) (2017)

We present a recommender system anticipated to be used by community of gamers. This system filters out or evaluate games through the opinions of other similar gamers using collaborative filtering technique and suggest those to the intended user. The system uses individual ratings given by the members of community, along-side rating of the games that a particular gamer likes, in order to predict and recommend new games to that gamer. The aim is to recommend games that match the user preferences and then user-based collaborative filtering is applied on the individual ratings of the games for a particular gamer to find similarity between those gamers. Genre-based filter is smeared on the shared rated games. The prediction algorithm is also tested on a larger standard dataset, Movie Lens, in order to verify the prediction accuracy. The results of our collaborative filtering approach is also compared using Mean Absolute Error. A working web based system is presented that found high user satisfaction in terms of usability and recommendation quality.
Early reduction of immune activation in lymphoid tissue following highly active HIV therapy (1998)

Although immune activation may be the direct consequence of HIV replication, HAART-associated reconstitution begins with a reduction in inflammatory cytokine production which precedes the elimination of local proviral reservoirs.
Cardiopulmonary Resuscitation (1992)

CARDIOPULMONARY arrest can be defined as the abrupt cessation of spontaneous and effective ventilation and systemic perfusion (circulation). Cardiopulmonary resuscitation (CPR) provides artificial ventilation and circulation until advanced cardiac life support can be provided and spontaneous cardiopulmonary function restored. Patients most likely to benefit from CPR (i.e., to be successfully resuscitated) include the following: those with witnessed sudden arrest due to ventricular fibrillation outside the hospital, when electrical countershock can be performed within approximately seven to eight minutes; hospitalized patients with primary ventricular fibrillation and ischemic heart disease; those with cardiac arrest in the absence of life-threatening coexisting conditions; and . . .
Thermal reemission of trapped electrons in SiO2 (1978)

Electron trapping by neutral trap centers in SiO2 was studied at 77 K and at room temperature, using n-channel silicon-gate IGFET structures. The electrons were injected in the dark using the forward-bias pulsed injection method. The results show that electron trapping by the neutral centers was one to two orders of magnitude more efficient at 77 K than at room temperature; which may be compared with the previously reported electron trapping by Coulomb-attractive centers where the capture cross sections at room temperature and at 77 K were about the same. For injected electron concentrations of less than 1016 cm−2, more than 90% of the electron trapping at 77 K was due to shallow-level centers where the captured electrons were thermally reemitted as the samples were warmed to room temperature. The concentrations of these shallow-level traps in dry, wet, and HCl oxides were about the same, regardless of whether the aluminum evaporation was by electron-beam or by rf heating in a tantalum boat. The capture cross section of these traps at 77 K was estimated to be about 10−15 cm2 at Eox=1×106 V/cm, decreasing slowly with increases in the oxide field. Thermally stimulated reemission measurements were made by monitoring the gate voltage shifts at constant channel conductance. Analyses of the results indicated a broad energy distribution for these shallow-level traps, with a peak at 300±50 meV below the conduction-band edge of SiO2 and a half-width of about 200 meV. A small portion of the enhanced trapping at 77 K was attributable to deep-level centers where the captured electrons were not thermally reemitted at room temperature.
Control of fungal growth with sphagnum for cold stratification and germination of tree seeds. (1998)

A method for seed germination has been practiced at the Taiwan Forestry Research Institute, Taiwan since 1985 and is worthy of introduction to other users. The method involves germinating seeds in a mixture with moist sphagnum in a polyethylene bag sealed with adequate air inside and placing the bags vertically in trays at required germination conditions. The water content of sphagnum was 85% (fresh weight basis). Since the bags can stand side by side, the space needed for germination is much reduced. Five isolates of Trichoderma viride (fungi), and 5 of actinomycetes were identified as associated with sphagnum. They were also identified as antagonistic to the microorganisms which cause mold development on seeds. The sphagnum medium can provide a germination condition which prevents the spread of mold which has been found to be of common occurrence in seeds requiring prolonged incubation periods in the traditional filter paper germination method of tree seeds. The seed germination rates, however, obtained in different germination media did not respond to the extent of mold contamination. In another experiment, tree seeds embedded in sphagnum medium were found to be significantly better protected from mold development than were naked seeds in the wet storage condition. Therefore sphagnum medium has great advantages for seeds which need a prolonged period of cold stratification.
Natural superhydrophilicity and photocatalytic properties of sol–gel derived ZnTiO3-ilmenite/r-TiO2 films (2010)

The additive free heteronucleation and nanocrystallization of ternary Zn(x)Ti(y)O(z) sols and coatings is presented. A proper adjustment of the Zn/Ti ratio in the sol allows the formation of elaborate superhydrophilic cubic spinel-like Zn(2)TiO(4), c-ZnTiO(3) or h-ZnTiO(3)-ilmentite/r-TiO(2)-rutile films. Their morphology and natural superhydrophilicity can be fine-tuned by the inclusion of 5% silica. This doping step delivers high dye intake capacities and water contact angle values below 3°. XPS analysis indicates that Zn and Si enrichment enables greater surface hydroxylation and thus improved water wetting behaviour. The transparent h-ZnTiO(3)-ilmenite/r-TiO(2) nanocomposite coatings deposited on glass and Si-wafers show a remarkable activity in the photomineralization of fatty-acids.
[Infrated diagnosis in ophthalmology]. (1978)

Half a century ago Richard Skalak [see T.C. Skalak, A dedication in memoriam of Dr. Richard Skalak, Annual Review of Biomedical Engineering 1 (1999) 1–18] published a paper with the title "An extension of the theory of water hammer" [R. Skalak, An Extension of the Theory of Water Hammer, PhD Thesis, Faculty of Pure Science, Columbia University, New York, USA, 1954; R. Skalak, An extension of the theory of water hammer, Water Power 7/8 (1955/1956) 458–462/17–22; R. Skalak, An extension of the theory of water hammer, Transactions of the ASME 78 (1956) 105–116], which has been the basis of much subsequent work on hydraulic transients with fluid–structure interaction (FSI). The paper considers the propagation of pressure waves in liquid-filled pipes and the coupled radial/axial response of the pipe walls. In a tribute to Skalak's work, his paper is revisited and some of his less-known results are used to assess the dispersion of pressure waves in long-distance pipelines. Skalak's theory predicts that the spreading of wave fronts due to FSI is small, at most of the order of 10 pipe diameters.
Evaluation of a buried vertical well leachate recirculation system for municipal solid waste landfills (2016)

Vertical liquids addition systems have been used at municipal landfills as a leachate management method and to enhance biostabilization of waste. Drawbacks of these systems include a limitation on pressurized injection and the occurrence of seepage. A novel vertical well system that employed buried wells constructed below a lift of compacted waste was operated for 153 days at a landfill in Florida, USA. The system included 54 wells installed in six clusters of nine wells connected with a horizontally-oriented manifold system. A cumulative volume of 8430 m<sup>3</sup> of leachate was added intermittently into the well clusters over the duration of the project with no incidence of surface seeps. Achievable average flow rates ranged from 9.3 × 10<sup>-4</sup> m<sup>3</sup> s<sup>-1</sup> to 14.2 × 10<sup>-4</sup> m<sup>3</sup> s<sup>-1</sup>, which was similar to or greater than flow rates achieved in a previous study using traditional vertical wells at the same landfill site. The results demonstrated that pressurized liquids addition in vertical wells at municipal solid waste landfills can be achieved while avoiding typical operational and maintenance issues associated with seeps.
Association between 25-hydroxyvitamin D levels and cognitive performance in middle-aged and older European men (2009)

In this study, lower 25(OH)D levels were associated with poorer performance on the DSST. Further research is warranted to determine whether vitamin D sufficiency might have a role in preserving cognitive function in older adults.
