Pressure swing permeation: Novel process for gas separation by membranes (2000)

Abstract A novel process for gas separation, called pressure swing permeation, was investigated to elevate the relatively low permeate pressure by pressurization with high‐pressure feed gas, thereby reducing or eliminating additional permeate compression costs where a pressurized permeate is required. This process uses two or more membrane modules and operates in a cyclic fashion, with each module repeatedly undergoing the sequential steps of feed admission and permeation, residual removal, permeate reception, permeate pressurization, and product withdrawal. The unsteady‐state permeation associated with pressure swing permeation was studied parametrically, and a bench‐scale unit compromising two hollow‐fiber membrane modules in parallel was tested for H 2 /N 2 separation to demonstrate the effectiveness of the process. The permeate product at a pressure as high as the feed pressure can be produced without using a compressor. This is impossible with traditional steady‐state processes where a pressure differential across the membrane must be maintained. The pressure swing permeation is analogous to pressure swing adsorption and has the potential to be synergistically integrated with the pressure swing adsorption process for enhanced separation of gases.
Nitrogen Monoxide Activates Iron Regulatory Protein 1 RNA-Binding Activity by Two Possible Mechanisms:  Effect on the [4Fe-4S] Cluster and Iron Mobilization from Cells (2000)

The iron-regulatory protein 1 (IRP1) regulates the expression of several molecules involved in iron (Fe) metabolism by reversibly binding to iron-responsive elements (IREs) in the untranslated regions (UTR) of particular mRNA transcripts. Several studies have indicated that nitrogen monoxide (NO) may influence IRP1 RNA-binding activity by a direct effect on the [4Fe-4S] cluster of the protein. It has also been suggested that NO may act indirectly on IRP1 by affecting the intracellular Fe pools that regulate the function of this protein [Pantopoulous et al. (1996) Mol. Cell. Biol. 16, 3781-3788]. There is also the possibility that NO may S-nitrosate sulfhydryl groups that are crucial for mRNA binding and decrease IRP1 activity by this mechanism. We have examined the effect of a variety of NO donors [e.g., S-nitroso-N-acetylpenicillamine (SNAP), spermine-NONOate (SperNO), and S-nitrosoglutathione (GSNO)] on IRP1 RNA-binding activity in both LMTK(-) fibroblast lysates and whole cells. In cell lysates, the effects of NO at increasing RNA-binding activity were only observed when cells were made Fe-replete. Under these circumstances, IRP1 contains an [4Fe-4S] cluster that was susceptible to NO. In contrast, when lysates were prepared from cells treated with the Fe chelator desferrioxamine (DFO), NO had no effect on the RNA-binding activity of IRP1. The lack of effect of NO under these conditions was probably because this protein does not have an [4Fe-4S] cluster. In contrast to the NO generators above, sodium nitroprusside (SNP) decreased IRP1 RNA binding when cells were incubated with this compound. However, SNP had no effect on IRP1 RNA-binding activity in lysates, suggesting that the decrease after incubation of cells with SNP was not due to S-nitrosation of critical sulfhydryl groups. Apart from the direct effect of NO on IRP1 in Fe-replete cells, we have shown that NO generated by SNAP, SperNO, and GSNO could also mobilize Fe from cells. When NO generation was induced in RAW 264.7 macrophages, an increase in IRP1 RNA-binding activity occurred but there was only a small increase in Fe release. Our results suggest that NO could activate IRP1 RNA-binding by two possible mechanisms: (1) its direct effect on the [4Fe-4S] cluster and (2) mobilization of (59)Fe from cells resulting in Fe depletion, which then increases IRP1 RNA-binding activity.
Human-readable fiducial marker classification using convolutional neural networks (2017)

Many applications require both the location and identity of objects in images and video. Most existing solutions, like QR codes, AprilTags, and ARTags use complex machine-readable fiducial markers with heuristically derived methods for detection and classification. However, in applications where humans are integral to the system and need to be capable of locating objects in the environment, fiducial markers must be human readable. An obvious and convenient choice for human readable fiducial markers are alphanumeric characters (Arabic numbers and English letters). Here, a method for classifying characters using a convolutional neural network (CNN) is presented. The network is trained with a large set of computer generated images of characters where each is subjected to a carefully designed set of augmentations designed to simulate the conditions inherent in video capture. These augmentations include rotation, scaling, shearing, and blur. Results demonstrate that training on large numbers of synthetic images produces a system that works on real images captured by a video camera. The result also reveal that certain characters are generally more reliable and easier to recognize than others, thus the results can be used to intelligently design a human-readable fiducial markers system that avoids confusing characters.
Direct Patterning of Spin-on-Glass Materials by ArF Excimer Laser Irradiation and Their New Application to Hard-mask Processes (1996)

Several spin-on-glass (SOG) materials were examined as single layer resists for ArF excimer laser lithography, with the goal of directly forming a hard mask from these materials for dry-etching underlying metal films. Perhydro-silazane (PHSN) was found to be photo-reactive at 193 nm wavelength as well as polyphenylmethyl-silsesquioxane (PMSQ) and polyhydroxybenzyl-silsesquioxane (HSQ), which we have reported previously. These materials showed a sufficient resolution performance and sensitivity at 193 nm. The Fourier-transform infrared (FTIR) and X-ray photoelectron spectrometry (XPS) analyses showed that the basic reaction is photo-oxidation, though the imaging mechanism in each material is quite different. The etching resistance of these materials was significantly improved by special treatment after patterning, whereas those without the treatment were insufficient. For example, etching rate of PHSN after baking in steam ambient was comparable to that for CVD SiO 2 in RIE using SF 6 gas. 0.2 µ m patterns were transferred into poly-Si films by dry-etching using these materials as hard masks.

Blind separation of delayed sources based on information maximization (2002)

Bell and Sejnowski (see Neural Computation, vol.7, no.6, p.1004-34, 1995) have presented an approach to blind source separation based on the information maximization principle. We extend this approach into more general cases where the sources may have been delayed with respect to each other. We present a network architecture capable of coping with such sources, and we derive the adaptation equations for the delays and the weights in the network by maximizing the information transferred through the network. Examples using wideband sources such as speech are presented to illustrate the algorithm.

Essential lessons fot the success of telehomecare : why It's not plug and play (2012)

The technology underpinning the various types of Telehomecare available has been current for more than a decade, and the time is right for an evaluation of both the technology and the effectiveness of Telehomecare as a system which contributes to the delivery of care within the home. The field is complex, encompassing multiple applications which monitor things such as task oriented behavior; lifestyle; vital signs; environmental extremes (such as carbon monoxide levels); and passive personal emergency response systems. All of these applications are based upon the collection of data within the home by a device which translates that data into information and transmits it to an external location, prompting some type of action if necessary. This book brings together the views and experience of a wide variety of contributors involved in the research and application of Telehomecare. It is divided into two sections, containing contributions from the United States, the United Kingdom and the Netherlands. Each section, comprises chapters written from three different perspectives: research-based, business and the implementation of care. The authors include academic researchers, policy experts, individuals with direct business experience and care providers from each of the three countries. The book reflects on where Telehomecare is today and speculates as to what the future might hold for the field. It will be of interest to all those involved in caring for people in their own homes.
Clinical applications of aptamers and nucleic acid therapeutics in haematological malignancies (2011)

Haematological malignancies result from a heterogeneous mix of genetic mutations and chromosome aberrations and translocations. Targeted therapies, such as the anti-CD20 antibody rituximab, or the BCR-ABL1 inhibitor imatinib, have proven to be effective treatments in the management of some of these malignancies, though relapsing or refractory disease is still common. Nucleic acid-based therapies have also entered the clinical arena, providing an alternative, complementary approach. The forerunner of these therapies were the antisense oligonucleotides, but their scope has expanded to include short-interfering RNA (siRNA), microRNA, decoy oligonucleotides and aptamers. These can be used either as mono-therapeutics, in conjunction with current chemotherapy regimens, or in combination with each other to improve therapeutic efficacy. Not only can these nucleic acid-based therapies silence target genes, they also have the potential of restoring gene function. While challenges remain in delivering effective doses of nucleic acid in vivo, these are steadily being met, suggesting an optimistic future in the treatment of haematological malignancies. This review summarizes the application of nucleic acid-based therapeutics, particularly aptamers, in the diagnosis and treatment of haematological malignancies.
Recent Advances in Manufacturing Innovative Stents (2020)

Cardiovascular diseases are the most distributed cause of death worldwide. Stenting of arteries as a percutaneous transluminal angioplasty procedure became a promising minimally invasive therapy based on re-opening narrowed arteries by stent insertion. In order to improve and optimize this method, many research groups are focusing on designing new or improving existent stents. Since the beginning of the stent development in 1986, starting with bare-metal stents (BMS), these devices have been continuously enhanced by applying new materials, developing stent coatings based on inorganic and organic compounds including drugs, nanoparticles or biological components such as genes and cells, as well as adapting stent designs with different fabrication technologies. Drug eluting stents (DES) have been developed to overcome the main shortcomings of BMS or coated stents. Coatings are mainly applied to control biocompatibility, degradation rate, protein adsorption, and allow adequate endothelialization in order to ensure better clinical outcome of BMS, reducing restenosis and thrombosis. As coating materials (i) organic polymers: polyurethanes, poly(ε-caprolactone), styrene-b-isobutylene-b-styrene, polyhydroxybutyrates, poly(lactide-co-glycolide), and phosphoryl choline; (ii) biological components: vascular endothelial growth factor (VEGF) and anti-CD34 antibody and (iii) inorganic coatings: noble metals, wide class of oxides, nitrides, silicide and carbide, hydroxyapatite, diamond-like carbon, and others are used. DES were developed to reduce the tissue hyperplasia and in-stent restenosis utilizing antiproliferative substances like paclitaxel, limus (siro-, zotaro-, evero-, bio-, amphi-, tacro-limus), ABT-578, tyrphostin AGL-2043, genes, etc. The innovative solutions aim at overcoming the main limitations of the stent technology, such as in-stent restenosis and stent thrombosis, while maintaining the prime requirements on biocompatibility, biodegradability, and mechanical behavior. This paper provides an overview of the existing stent types, their functionality, materials, and manufacturing conditions demonstrating the still huge potential for the development of promising stent solutions.

[Impact of exercise test on signal-averaged ECG in patients with myocardial infarction]. (1992)

To examine the impact of exercise test (bicycle ergometry) and exercise-induced transient ischemic changes in ST segment on signal-averaged ECG parameters, the authors studied a homogeneous group including 65 patients (62 males and 3 females) with a 2-3-week history of primary myocardial infarction. The findings showed that induced myocardial ischemia caused no significant changes in signal-averaged ECG and late potentials, exercise might induce late potentials without clear-cut ECG signs of myocardial ischemia. It was also indicated that exercise-labile late potentials were significantly more frequently associated with the development of ventricular arrhythmias than steady late potentials.
Myocardial Electrical Impedance Responds to Ischemia and Reperfusion in Humans (2004)

Myocardial electrical impedance (MEI) is correlated to ischemia and reperfusion of the heart muscle. The entire body of work with MEI to this point has been carried out in animal subjects in vivo and excised tissue samples. In this study, we measured MEI clinically for the first time in human patients who were undergoing off-pump coronary artery bypass (OPCAB) surgery. MEI was measured with a monitor designed in this laboratory and approved by the FDA for use on human subjects. Our patient population (n = 18) had a 70%-100% stenosis of the diseased coronary artery targeted for bypass. We measured MEI continuously during surgery and at 3, 6, 24, and 72 h postoperatively from two temporary pacing electrodes attached to the heart muscle. Absolute baseline impedance ranged from 173 to 729 ohms. MEI increased with occlusion of the diseased artery prior to bypass. The percent increase from baseline was inversely correlated to the percent stenosis of the diseased artery. MEI decreased below baseline immediately on reperfusion following bypass in all patients and continued decreasing over the measurement period. MEI is a reliable clinical indicator of ischemia and reperfusion in humans and may indicate the effectiveness of coronary artery surgery. The parameter may have monitoring and diagnostic value in heart disease in humans.

Antiobesity Actions of <i>Zingiber officinale</i> Roscoe (2005)

Zingiber officinale Roscoe has been used as a folk medicine in China. An aqueous extract of Z. officinale Roscoe inhibited the hydrolysis of triolein emulsified with phosphatidylcholine by pancreatic lipase in vitro and it reduced the elevation of rat plasma triacylglycerol levels 1 and 2 h after oral administration of a lipid emulsion containing corn oil. These results suggest that the aqueous extract of Z. officinale Roscoe might inhibit the intestinal absorption of dietary fat by inhibiting its hydrolysis. Therefore we investigated the antiobesity effects of the aqueous extract of Z. officinale Roscoe by feeding a high-fat diet to mice for 8 weeks. Body weights at 2-8 weeks and final parametrial adipose tissue weights were significantly lower in mice fed the high-fat diet containing 3% aqueous extract of Z. officinale Roscoe than in the controls fed the high-fat diet. Feeding a high-fat diet containing 1% aqueous extract of Z. officinale Roscoe also significantly reduced final parametrial adipose tissue weights that were elevated in mice fed the high-fat diet alone. Our data suggest that the antiobesity effect of aqueous extract of Z. officinale Roscoe in mice fed a high-fat diet may be due in part to the inhibition of intestinal absorption of dietary fat by the active compounds of Z. officinale Roscoe.

Vehicular Position Tracking Using LTE Signals (2016)

This paper proposes and validates, in the field, an approach for position tracking that is based on Long-Term Evolution (LTE) downlink signal measurements. A setup for real data live gathering is used to collect LTE signals while driving a car in the town of Rapperswil, Switzerland. The collected data are then processed to extract the received LTE cell-specific reference signals (CRSs), which are exploited for estimating pseudoranges. More precisely, the pseudoranges are evaluated by using the “ESPRIT and Kalman Filter for Time-of-Arrival Tracking” (EKAT) algorithm and by taking advantage of signal combining in the time, frequency, spatial, and cell ID domains. Finally, the pseudoranges are corrected for base station's clock bias and drift, which are previously estimated, and are used in a positioning filter. The obtained results demonstrate the feasibility of a position tracking system based on the reception of LTE downlink signals.
