Modulation encoding and iterative detection for imaging page-oriented optical data storage (2003)

Various types of holographic and imaging volumetric page-oriented optical data storage (PODS) systems have great potential to provide data storage with larger capacity, faster access time, and higher transfer rates [1]. The usable data capacity is quantified by the code rate, or percentage of theoretical storage capacity that is actually useable for storing information at a minimum acceptable bit-error rate (BER). The BER is controlled by using a combination of channel coding (error-correcting coding or ECC) on the digital data, and a modulation coding procedure that formats the data for the physical storage medium. For a given coding scheme and level of signal processing, increasing the data packing density increases the code rate at the expense of lower BER due to the presence of spatial intersymbol interference (ISI), interpage interference (IPI) and noise. ISI and IPI are due to the point-spread function of the recording and readout optics. Some modulation codes [2] add redundant information to preserve the signal integrity and simplify the detection procedure. We describe a n iterative computational imaging technique that maintains a minimum required modulation coding BER (generally 10-3 or better) while improving the overall code rate and capacity of a page-oriented imaging optical data storage system
Time-Varying Volterra System Identification Using Kalman Filtering (2006)

Most nonlinear system identification methods based on Volterra model assume that the underlying system is time-invariant. In this paper, a novel identification method for time-varying Volterra systems (TVVS) is proposed. We view this problem from a different perspective in the sense that the system identification problem is converted to a state estimation problem of a dynamic system. The time-varying Volterra kernels are governed by a Gauss-Markov stochastic difference equation upon which a state-space representation of time-varying Volterra systems is built. The state transition matrix and noise covariance of the underlying state equations are usually unknown. Therefore, we develop a method to estimate these unknown quantities. Finally, a Kalman filtering scheme is utilized to identify and track the time-varying Volterra system. Simulation examples are given to illustrate the better performance of the proposed method as compared with other adaptive identification methods such as the LMS and RLS algorithms.

Plasma sRAGE is independently associated with increased mortality in ARDS: a meta-analysis of individual patient data (2018)

Higher baseline plasma sRAGE was associated with higher 90-day mortality in patients with ARDS, independently of driving pressure and tidal volume, thus reinforcing the likely contribution of alveolar epithelial injury as an important prognostic factor in ARDS. Registration: PROSPERO (ID: CRD42018100241).
A LOW VOLTAGE TUNABLE ANALOG PHASE SHIFTER UTILIZING FERROELECTRIC VARACTORS (2008)

ABSTRACT A distributed transmission line phase shifter was implemented by periodically loading a coplanar transmission line using ferroelectric varactors in a shunt configuration. A single dc bias applied to the phase shifter circuit provides a large relative phase shift. A relative phase shift of ∼ 305 degrees was obtained at 20 GHz for a dc bias of only 5 V.
In Vitro Evaluation of the Antioxidant, 3,5-Dihydroxy-4-ethyl-trans-stilbene (DETS) Isolated from Bacillus cereus as a Potent Candidate against Malignant Melanoma (2016)

3,5-dihydroxy Q1 -4-ethyl-trans-stilbene (DETS) is a natural stilbene, which was first identified as bioactive bacterial secondary metabolite isolated from Bacillus cereus associated with a rhabditid entomopathogenic nematode. The present study was intended to investigate the antioxidant and anticancer activity of this compound in vitro. Antioxidant activity was investigated by assaying DPPH free radical scavenging, superoxide radical-(O2..) scavenging, hydroxyl radical scavenging and metal chelating activity, which proved that the compound is a powerful antioxidant. The metal chelating activity of DETS was higher than butylated hydroxyanisol (BHA) and gallic acid, two well-known antioxidants. As the molecule exhibited strong antioxidant potential, it was further evaluated for cytotoxic activity toward five cancer cells of various origins. Since the compound has a strong structural similarity with resveratrol (trans- 3,4,5-trihydroxystilbene), a well-studied chemopreventive polyphenolic antioxidant, its anticancer activity was compared with that of resveratrol. Among the five cancer cells studied, the compound showed maximum cytotoxicity toward the human melanoma cell line, [A375, IC50: 24.01 μM] followed by cervical [HeLa-46.17 μM], colon [SW480- 47.28 μM], liver [HepG2- 69.56 μM] and breast [MCF-7- 84.31 μM] cancer cells. A375 was much more sensitive to DETS compared to the non-melanoma cell line, A431, in which the IC50 of the compound was more than double (49.60 μM). In the present study, the anticancer activity of DETS against melanoma was confirmed by various apoptosis assays. We also observed that DETS, like resveratrol, down-regulates the expression status of major molecules contributing to melanoma progression, such as BRAF, β-catenin and Brn-2, all of which converge in MITF-M, the master regulator of melanoma signaling. The regulatory role of MITF-M in DETS-induced cytotoxicity in melanoma cells was confirmed by comparing the cytotoxicity of DETS in A375 cells (IC50-24.01 μM), with that in SK-MEL-2 (IC50-67.6 μM), another melanoma cells which highly over-express MITF-M. The compound arrests the cells at S-G2 transition state of the cell cycle, as resveratrol. Our results indicate that DETS is a powerful antioxidant, having anticancer efficacy comparable with that of resveratrol, and is a potential candidate to be explored by in vivo studies and in-depth mechanistic evaluation. To our knowledge, this is the first report on the antioxidant and anticancer properties of DETS.
An accelerometer-based physical rehabilitation system (2003)

This paper presents a portable physical rehabilitation monitoring system based on a personal network of intelligent sensors. Rehabilitation is traditionally carried out in hospitals under supervision of qualified personnel. However, significantly better results could be achieved using out-of-hospital portable monitoring to allow patients computer-assisted rehabilitation in their homes. The new generation of personal digital assistants (PDA), such as Compaq iPAQ, offers large processing power, decent graphical user interface, and compact flash based secondary memory. Therefore, they are perfectly suited for portable monitoring units. Individual sensors are positioned on limbs to analyze movements using 2-axis MEMS accelerometers. The system monitors periods and forces of individual sensors, visualizing relevant physiological data in real-time on PDA, and archiving progress data on compact flash. A specialist supervises current advance and sets new optimum rehabilitation modes, thresholds for forces, step periods, etc. The system generates real-time warnings when predefined thresholds have been exceeded. We are developing a system for hip and knee replacement rehabilitation, as well as general physical rehabilitation. Other possible applications of our system include rehabilitation of stroke and heart attack patients.
The effect of nitric oxide anneals on silicon vacancies at and very near the interface of 4H SiC metal oxide semiconducting field effect transistors using electrically detected magnetic resonance (2013)

We use three electrically detected magnetic resonance (EDMR) approaches to explore nitric oxide (NO) annealing in 4H SiC metal-oxide-semiconductor field-effect transistors (MOSFETs). One approach is sensitive to defects at the interface and those extending into the SiC. Two of these approaches are particularly sensitive to SiC/SiO2 interface defects. They show that NO anneals decrease the EDMR response. Since this and earlier studies indicate the ubiquitous presence of silicon vacancy centers in SiC MOSFETs, our results provide strong circumstantial evidence that these defects play an important role in limiting device performance and that NO anneals are effective in reducing their populations.

Development of a Novel Adsorptive Membrane Chromatographic Method for the Fractionation of Polyphenols from Bilberry (2012)

A novel membrane chromatographic method with a membrane adsorber (Sartobind S) has been developed on the laboratory scale that allows a fractionation of bilberry (Vaccinium myrtillus) constituents into the following three groups of polyphenols: anthocyanins, copigments, and polymers. By using this methodology, a pure anthocyanin fraction free of other copigments and polymeric phenols can be obtained. Using this approach, it provides fractions allowing a more thorough testing of the biological effects of the individual groups of bilberry polyphenols as well as the study of possible synergistic effects between these different groups of bioactive constituents from bilberry.
Separation of Thiophene from Aliphatic Hydrocarbons Using Tetrahexylammonium-Based Deep Eutectic Solvents as Extracting Agents (2017)

Catalytic hydrodesulfurization is the common process that is used in the industry to achieve low sulfur concentrations in oil fuels. However, it is usually conducted at relatively high pressure and temperature resulting in an expensive and energy-consuming process. Aiming to reduce the energy requirements of this separation, liquid–liquid extraction is considered. In this work, two deep eutectic solvents (DESs) were evaluated for their extraction properties of sulfur derivatives from two aliphatic hydrocarbons via liquid–liquid extraction. The mixtures thiophene/n-hexane and thiophene/n-octane were selected as oil models. The selected DESs were: (i) tetrahexylammonium bromide/ethylene glycol with molar ratio = 1:2 (DES 1) and (ii) tetrahexylammonium bromide/glycerol with molar ratio = 1:2 (DES 2). To confirm the suitability of the DESs for the system {aliphatic + thiophene + DES}, the binary solubility of thiophene/DES and aliphatic/DES was measured at T/K = 298 and atmospheric pressure. Then, the liquid–liquid equilibrium (LLE) data of the ternary systems {n-hexane + thiophene + DES 1}, {n-hexane + thiophene + DES 2}, {n-octane + thiophene + DES 1}, and {n-octane + thiophene + DES 2} were determined at T/K = 298 and atmospheric pressure. The experimental LLE data were correlated using the nonrandom two-liquid thermodynamic model. Also, the solute distribution ratios and the selectivities were calculated from the experimental LLE data and compared to the relevant literature. Finally, the DESs were successfully regenerated by means of vacuum evaporation. It was found that the DESs are potential solvents for extractive desulfurization processes.
Properties of mixed composition IR optical thin films (1990)

Mixing two optical materials greatly increases the range of properties that are available from a finite number of discrete materials. The properties of composite films are often unique and unobtainable from any single material. Composition-dependent structural, optical, and mechanical properties of co-deposited and layered infrared optical thin-film materials were investigated. The material pairs studied were Si/ZnSe, Si/AlF 3 , LaF 3 /ZnSe, and YF 3 /ZnSe. Information will be presented on stress, optical properties, scatter and morphology, microhardness, and crystallization behavior and microstructural development upon annealing.
Mixing Behavior During the Processing of Rubber by New Type Rotors in an Internal Mixer (2020)

This chapter investigates the basic mixing behavior in a two-dimensional internal mixer equipped with the various shapes of the separated counterrotating rotors by visualizing methods, and the rotors showing good mixing ability have been found. Experimental work was carried out with a two-dimensional mixer with various types of rotors. The effect of the shape of the rotors on the mixing behavior of BR rubber in a two-dimensional internal mixer was shown, and it is obvious that the void in the mixer affects the mixing behavior. The mixing behavior of BR rubber and the tracer rubber particles in a three-dimensional internal mixer was investigated using a vulcanization reaction to fix the rubber particles in the rubber. Various types of batch internal mixers in which carbon black, additives, and vulcanizing agents were incorporated into solid rubbers have been used for a short time in the rubber industry.
`The Auld Warld is By Wi': W.L. Lorimer's The New Testament in Scots (2004)

Multiple myeloma (MM) is a hematological malignancy characterized by aberrant clonal plasma cells in the bone marrow. Despite significant advances in the treatment of MM, infection remains a main cause of death. MM patients have an increased risk of infection compared to their healthy counterparts due to several factors related to underlying disease, advanced age, comorbidities, and MM treatment. MM patients are at high risk of infection during the first 3 months after diagnosis and during relapse. Anti-myeloma drugs frequently result in severe immunosuppression and increased risk of infection. Proteasome inhibitors deplete T cells, lenalidomide and pomalidomide induce neutropenia, and CD38 antibodies reduce B cell function. To prevent infection in MM patients, we should take appropriate action by medical prophylaxis and vaccination.
Use of 3-aminopropanol as an ethanolamine analogue in the study of phospholipid metabolism in Tetrahymena (1988)

About 50% of the ethanolamine in phosphatidylethanolamine in Tetrahymena is replaced by 3-aminopropan-1-ol when the compound is added to the growth medium. The phosphatidylpropanolamine which is formed is not converted into the corresponding phosphatidylcholine analogue by methylation. There is an increase in phosphatidylcholine formed by the phosphotransferase pathway from free [3H]choline and a decrease in the phosphatidylcholine formed by the methylation pathway from [14C]methionine. The nature of the observed phospholipid alterations suggests that the regulation of phosphatidylcholine biosynthesis in Tetrahymena may be different from that found in higher eukaryotes.

Designing a wireless sensor system for continuous monitoring of the cervical dilation of a pregnant woman (2009)

A novel electronic sensor system is designed to continuously monitor the dilation of the cervix of a pregnant female approaching labour and delivery. The system is capable of wirelessly transmitting the progress of dilation to a central monitoring agency that can get in touch with the attending physician and/or the hospital of the pregnant female. Using wireless telephony, the monitoring agency and/or the physician can advise the female about the medical care she needs at that moment, even though the female might be at her home or away from home, and away from the medical facility. This is an expanded version of a paper presented at the 3rd IEEE International Workshop on Medical Measurements and Applications, 9?10 May 2008, Ottawa, ON, Canada.
Molecular dynamics simulation of binary hard sphere crystal/melt interfaces (1999)

The structure and thermodynamics of the (100) and (111) disordered face-centred cubic (fcc) crystal/melt interfaces for a binary hard sphere system have been examined using molecular dynamics simulation. This study is an extension of previous work (Davidchack, R. L., and Laird, B. B., 1996, Phys. Rev. E, 54, R5905), in which preliminary data for the (100) interface were reported. Density and diffusion profiles on both fine and coarse grained scales are calculated and analysed, leading to the conclusion that equilibrium interfacial segregation is minimal in this system.
Chemotherapy Controls Metastasis Through Stimulatory Effects on GRP78 and Its Transcription Factor CREB3L1 (2020)

To achieve a cure for metastatic breast cancer, further understanding of molecular drivers of the metastatic cascade is essential. Currently, chemotherapy regimens include doxorubicin and paclitaxel which act in part by inducing the unfolded protein response (UPR). The master regulator of the UPR, glucose regulated protein 78 (GRP78), localizes on the surface of tumor cells and is associated with metastatic disease. Cyclic AMP responsive element binding protein 3-like 1 (CREB3L1), a member of the UPR, is a breast cancer metastasis suppressor that acts on cyclic AMP to promote the expression of target genes including GRP78. The aim of the present study was to evaluate the effects of chemotherapy on CREB3L1 and cell-surface GRP78 expression and its association with the development of breast cancer metastasis. For this purpose, we use breast cancer cells migration <i>in vitro</i> assays and an <i>in vivo</i> metastatic mouse model. The results showed that chemotherapy activated CREB3L1 and enhanced cell-surface GRP78 expression specifically in triple-negative breast cancer cells (TNBC), reducing their migration and metastatic potential. CREB3L1 knockout (KO) in the triple negative MDAMB231 cell line using CRISPR/Cas9 technology led to inhibition of GRP78 expression and abrogation of the CREB3L1 metastatic suppression function. Inoculation of CREB3L1-KO MDAMB231 cells into a mouse metastatic model induced a massive metastatic profile which chemotherapy failed to prevent. These findings elucidate a potential pathway to the development of a novel treatment strategy for metastatic TNBC based on modulating CREB3L1 and cell-surface GRP78 expression by chemotherapy and GRP78-targeted drugs.
EUV pellicle qualification on transmission and reflectance (2019)

RI Research Instrument’s EUV pellicle transmission qualification tool EUV-PTT uses “effective inband EUV measurement” which is spectrally filtering emission of the EUV-Lamp to 2% bandwidth at 13.5 nm for measuring “as seen by the scanner”. Images of about 20*20 mm² are recorded in &lt; 5 seconds. A full pellicle characterization with &lt; 60 images taken is accomplished in less than one hour. Recently, we have performed some studies on applying this technique to carbon nano tube pellicles and on measuring the reflectance of pellicles which will be reported. The latter is heavily demanding as reflectances in the range of 0.01 % were measured with sensitivities and reproducibilities in the range of 0.002 %.
Solving flavor puzzles with quiver gauge theories (2006)

We consider a large class of models where the $SU(5)$ gauge symmetry and a Froggatt-Nielsen (FN) Abelian flavor symmetry arise from a $U(5)\ifmmode\times\else\texttimes\fi{}U(5)$ quiver gauge theory. An intriguing feature of these models is a relation between the gauge representation and the horizontal charge, leading to a restricted set of possible FN charges. Requiring that quark masses are hierarchical, the lepton flavor structure is uniquely determined. In particular, neutrino mass anarchy is predicted.
