Synthetic Iron Oxides as an Indicator of Reduction in Soils (IRIS) (2006)

Various circumstances in wetland delineation or mitigation strategies require the documentation of reducing conditions in soils. An innovative approach for assessing reduction in soils known as Indicator of Reduction in Soils (IRIS) has been recently introduced. IRIS tubes are manufactured by coating polyvinylchloride (PVC) pipe with a paint prepared from an Fe oxide (mainly ferrihydrite) suspension. When the iron oxide is synthesized by adding KOH to a FeCl 3 solution, the mineral phase is essentially pure ferrihydrite. Over time, and under particular conditions, the ferrihydrite is transformed to more crystalline forms such as goethite and hematite. The objectives of this study were (i) to assess the mineralogical composition of iron oxide paint synthesized for the manufacture of IRIS tubes and (ii) to assess the significance of mineralogical composition of the Fe oxide paint on desirable qualities for the construction of IRIS tubes. The effects of pH and storage time on the mineralogical alteration of ferrihydrite are examined and compared with performance of the paint by a scale for adhesion and durability. Paint composed of nearly pure ferrihydrite shows poor adhesion and durability. Data suggest that for paint to adhere well to the PVC tubing, the Fe oxide suspension must contain a minimum of 30 to 40% goethite. This desired paint composition can be facilitated during synthesis by titrating the Fe oxide suspension to pH 11 or 12 rather than pH 7.5, which is typically prescribed for the formation of synthetic ferrihydrite.
<title>Fingerprint identification with the joint transform correlator using multiple reference fingerprints</title> (1995)

A new binary joint transform correlator (BJTC) algorithm has been implemented which compares a target fingerprint with six reference fingerprints. The correlator uses the frame subtraction technique to achieve very dense packing of the images in this input plane. Six 128 X 64 reference prints and a target print are displayed simultaneously on a 256 X 256 input SLM. A peak-to-noise ratio (PNR) of 12.7 dB has been demonstrated experimentally, and a potential for a PNR as high as 41 dB is shown using simulation. This is compared to a PNR of 6.8 dB achieved without using frame subtraction. This demonstrates that through use of frame subtraction the input separation constraints for the BJTC are eliminated and performance is improved.

The primary structure and analysis of the squid kinesin heavy chain. (1990)

We report the cDNA sequence of the squid kinesin heavy chain and compared the predicted amino acid sequence with that of the Drosophila heavy chain as reported by Yang, J.T., Laymon, R.A., and Goldstein, L.S. B. (1989) Cell 56, 879-889). We compared the two kinesin sequences with regard to the predicted physicochemical parameters of hydrophobicity, charge, and propensities of the secondary conformations. A comparison of the sequences from the two species reveals the head, stalk, and tail domains because a reduced degree of conservation demarcates the stalk. The charge profile indicates that the head region is nearly neutral, the stalk region acidic, and the tail is basic. The Fourier transform analysis of the hydrophobic profile of the stalk shows predominant peaks at 1/3.5 and 1/2.3, which are indexed as the second and third orders of the period 7 residue. As in the Drosophila sequence, the rod domain is divided into an amino and a carboxyl subdomain by a predicted hinge region. We show that the disposition of hydrophobic residues is distinct in these two subdomains. In particular, the heptad repeat is more regular in the amino-terminal rod domain than in the carboxyl-terminal rod domain. The tail region is positively charged, a feature that is consistent with the known electrostatic interaction between the heavy chain and negatively charged surfaces such as glass coverslips and latex beads. Three monoclonal antibodies to the kinesin heavy chain have been mapped to a region within the carboxyl terminus of the stalk.
Carbon Dioxide Removal in a Membrane Contactor – Selection of Absorptive Liquid/Membrane System (2012)

This report demonstrates the application of the membrane contactor for carbon dioxide removal. The investigations were performed with the use of a single polypropylene capillary membrane. Two primary amines (monoethanolamine MEA, diglycolamine DGA), one secondary amine (diethanolamine DEA), one tertiary amine (methyldiethanolamine MDEA) were used to prepare absorbate solutions. Batch experiments were conducted for the counter-current flow with liquid on the tube side of the module. The system was investigated for aqueous solutions of amines and for the solutions with piperazine addition. The absorption kinetics with the use of primary amines appeared to be much faster than those of secondary and tertiary amines. The amine efficiency can be stated as follows: MEA>DGA>DEA>MDEA. Further investigations have shown/show that the presence of an activator improves the reaction and process kinetics and brings the DEA and MDEA efficiency to the level of primary amines. The influence of different types of amine solutions used as liquid absorbents on the stability of the membrane shows that these solutions do not wet PP (polypropylene) membranes even after 150 days' immersion in different absorbents.
Nanostructured conformable patch antenna array (2010)

Carbon nanotube (CNT) has emerged as potential candidate for replacement of conventional metal patch. The principal objective of our research is to develop nanostructure based flexible patch antenna array for multi frequency operation in Industrial, Scientific and Medical (ISM) band. Patch antenna design using CNT on flexible cotton sheets and CNT silver composites as conductive patch and ground plane has been simulated. Due to high conformability and conductivity of CNT all antenna parameters like VSWR, Return loss, Gain and radiation pattern meet design criteria. Our simulated antenna shows a return loss less than -10 dB and VSWR less than 2 at 2.06 GHz, 2.38 GHz and 2.49 GHz. A simulation of a versatile and conformable antenna design has also been done wherein the whole geometry is rolled up like patch array on cylindrical surface. This brings about conformability to the curved surfaces and integration with the structure which results in a unique antenna design.
The role of NLRP3 inflammasome in 5-fluorouracil resistance of oral squamous cell carcinoma (2017)

Our findings suggest that NLRP3 inflammasome promoted 5-FU resistance of OSCC both in vitro and in vivo, and targeting the ROS/NLRP3 inflammasome/IL-1β signaling pathway may help 5-FU-based adjuvant chemotherapy of OSCC.
Can telemetric home monitoring of implantable defibrillators increase the treatment's cost-effectiveness ratio? (2003)

Implantable defibrillators (ICDs) are the treatment of first choice concerning survived sudden cardiac death (SCD) or symptomatic ventricular tachycardias (VT). Technical progress now offers telemetric performed interrogations and controls including information about the system status, episodes detected and treated via so called home monitoring (HM). Target of this work was to bundle first results and experience from single cases from a systematic clinical investigation (= home - ICD trial) and define a model for an economic research on the cost-effectiveness ratio of the treatment. Till today 228 patients could be included in the trial. On the economic question a Markov-chain model with three abstracted types of complications and three layers of economic benefit could be set up and is shared for discussion.
Removal of proteins from natural rubber with urea (2004)

Abstract Removal of proteins from natural rubber was achieved by incubation of the rubber latex with urea in the presence of a surfactant to prevent the latex‐allergy caused with thin film products. Temperature, pH and time for the incubation were investigated to remove the proteins effectively, in which nitrogen content of the rubber was reduced to 0.02 from 0.38 wt% under the optimum condition. To remove further the proteins, deproteinization of natural rubber was made by incubation of the latex with proteolytic enzyme in the presence of a surfactant followed by incubation with urea. Amount of allergen decreased through the procedure to less than 0.7 μg/ml, which is a small amount of allergen compared to that for the commercial, deproteinized natural rubber.

Automated Decellularization of the Rodent Epigastric Free Flap: A Comparison of Sodium Dodecyl Sulfate–Based Protocols (2022)

A compact and integrated bioreactor can automate decellularization of free flaps to bioengineer regenerative constructs for future use in reconstruction of complex defects. A decellularization protocol with 5 days of 1% SDS exposure was the most successful to keep the residual DNA content at a minimum while preserving the structural integrity of the tissues.
Effect of BMI on toxicities and survival among adolescents and young adults treated on DFCI Consortium ALL trials (2023)

Adolescent and young adults (AYAs) with acute lymphoblastic leukemia (ALL) treated with asparaginase-containing pediatric regimens are commonly overweight or obese. We studied the association of body mass index (BMI) on outcomes of 388 AYAs aged 15 to 50 years treated on Dana-Farber Cancer Institute (DFCI) consortium regimens (2008-2021). BMI was normal in 207 (53.3%) and overweight/obese in 181 (46.7%). Patients who were overweight or obese experienced higher nonrelapse mortality (NRM; 4-year, 11.7% vs 2.8%, P = .006), worse event-free survival (4-year, 63% vs 77%, P = .003), and worse overall survival (OS; 4-year, 64% vs 83%, P = .0001). Because younger (aged 15-29 years) AYAs more frequently had a normal BMI (79% vs 20%, P < .0001), we conducted separate analyses in each BMI group. We found excellent OS among younger and older (30-50 years) AYAs with normal BMI (4-year OS, 83% vs 85%, P = .89). Conversely, in AYAs who were overweight/obese, worse outcomes were seen in older AYAs (4-year OS, 55% vs 73%, P = .023). Regarding toxicity, AYAs who were overweight/obese experienced higher rates of grade 3/4 hepatotoxicity and hyperglycemia (60.7% vs 42.2%, P = .0005, and 36.4% vs 24.4%, P = .014, respectively) but had comparable rates of hypertriglyceridemia (29.5% vs 24.4%, P = .29). In a multivariable analysis, higher BMI was associated with worse OS, hypertriglyceridemia was associated with improved OS, and age was not associated with OS. In conclusion, among AYAs treated on DFCI Consortium ALL regimens, elevated BMI was associated with increased toxicity, increased NRM, and decreased OS. The deleterious effect of elevated BMI was more pronounced in older AYAs.
Identification of novel, immune-mediating extracellular vesicles in human lymphatic effluent draining primary cutaneous melanoma (2019)

Epithelial tumors including melanoma often first metastasize to regional, sentinel lymph nodes (SLN). Thus, the presence of SLN metastases is a critical prognostic factor of survival. Prior to metastasis, accumulating evidence suggests the SLN is immunologically compromised; however, the process by which pre-metastatic niche formation occurs remains unknown. In this prospective study, freshly dissected, afferent lymphatic fluid was obtained during SLN biopsy in three patients with primary cutaneous melanoma. Lymphatic extracellular vesicles (L-EV) were visualized by transmission electron microscopy and proteomic cargo profiled by mass spectrometry. Flow cytometry assessed L-EV effects on autologous dendritic cell maturation <i>in vitro</i>. Immunogold electron microscopy and immunohistochemistry visualized expression of EV cargo within the primary tumor and SLN. Lymphatic extracellular vesicles from each afferent lymphatic channel demonstrated inhibition of autologous dendritic cell maturation. Proteomic profiling identified 81 peptides shared among the L-EV preparations including a signature of 18 immune-modulating proteins including previously established inhibitor of dendritic cell maturation, S100A9. Immunohistochemistry and immunogold electron microscopy confirmed S100A9 tracking along the lymphatic path, from keratinocytes in the primary tumor to sub-capsular macrophages in the SLN. Our findings suggest L-EV cargo may serve as early mediators of tumor-induced immune subversion in regional lymph nodes, by preceding malignant cells and trafficking within the lymphatic vasculature to harbor the first pre-metastatic niche.
Low-Temperature Combustion Synthesis and Characterization of Ce<sub>1-x</sub>Pr<sub>x</sub>O<sub>2-δ</sub> Solid Solutions (2008)

Pr2O3-doped ceria nanopowders were synthesized by a nitrate-citrate combustion process. This route is based on the gelling of nitrate solutions by the addition of citric acid and ammonium hydroxide, followed by an intense combustion process due to an exothermic redox reaction between nitrate and citrate ions. XRD analysis showed that no impurity were observed up to x=0.3 in Ce1-xPrxO2-δ systems. The influence of ignition temperature on the characteristics of the powders was studied. The change of the crystal structure with the content of doped Pr was investigated. The highest ionic conductivity, σ600°C=2.45×10-3S/cm, was found for the composition of x=0.15.
Timely prediction of low-altitude radar performance in operational environments using in situ atmospheric refractivity data (1990)

A shipboard radar decision aid that may be used to predict current low-altitude radar performance and assist the radar operator in maximising system capabilities in the existing propagation environment is discussed. The system, developed for use aboard US Navy AEGIS-class ships, uses expendable rocketborne radiosondes to make high-resolution measurements of the atmo sphere. A version of the Johns Hopkins University Applied Physics Laboratory&apos;s electromagnetic parabolic equation (EMPE) propagation model is used to calculate the effects of the measured refractivity environment on the propagation of energy radiated by the radar. A radar modeluses these data in predictions of the system&apos;s current low-altitude target detection capabilities. A colour display indicates the size of targets that may be detected through contour shading of a range-height display. The effects of many radar operator controllable options on target detectability may be evaluated in the current propagation environment with this system. A significant portion of the data acquisition-to-display process has been automated. Design and implementation of this system and results of recent at-sea testing are discussed.

Effect van chirurgische behandeling op patiënten met cerebrale parese: wel betere handvaardigheid, beleving competentie niet verbeterd (2010)

To examine the relationship between impaired manual dexterity and perceived competence in children with cerebral palsy and the effect of surgical intervention, with the question whether the perceived competence is applicable as an outcome measure for surgical reconstruction of hand function. The Dutch version of the Michigan Hand Outcomes Questionnaire (MHQ-DLV) for perceived manual dexterity and the Dutch version of the Harter Scales for perceived competence were used in a sample of 25 children and adolescents with hemiplegic cerebral palsy of the spastic type. 10 patients underwent surgical treatment to improve hand function. In this 'surgical group' both questionnaires were repeated at least one year postoperatively. Perceived manual dexterity was low (mean MHQ-DLV-score: 63.2; SD: 18.9), as were the scores of perceived overall competence (2.92; SD: 0.84), social competences (2.66; SD: 0.92) and athletic competences (2.29; SD: 0.79). There was no correlation between the degree of perceived impairment in manual dexterity and the perceived competence (r = -0.16; p = 0.43). After surgical reconstruction manual dexterity improved (mean increase in score: 24; SD: 10.4; p &lt;0.01), but perceived competence did not improve (p = 0.39). Children with cerebral palsy and impaired manual dexterity did have a lower perceived competence than children without this disorder. The extent to which manual dexterity was impaired did not correlate with the extent to which perceived competence was lowered. Surgical intervention substantially improved perceived manual dexterity, but perceived competence did not improve. Perceived competence does not seem to be applicable as an outcome measure for surgical reconstruction of manual dexterity
Fast gradient methods based global motion estimation for video compression (2003)

This paper presents a fast global motion estimation (GME) algorithm based on gradient methods (GM), which can be used for real-time applications, such as MPEG-4 video compression. Our approach improves existing state-of-the-art GME algorithms by introducing two major modifications: first, only a small subset (down-to 3%) of the original image pixels is used in the estimation process. Second, a warp-free formulation of the basic GM is derived, further decreasing the computational complexity. Experimental results show that a 20 fold computation complexity reduction is achieved, without compromising the GME accuracy and compression efficiency.
Design of a Thumb Strength Testing Device (2018)

The scope of the project was to design a pneumatic cylinder for measuring the resistive and applied force of the flexor pollicis longus (FPL) after anterior interosseous nerve (AIN) surgery. The patient’s distal section of the first phalange, of the thumb, is the area of evaluation. The device is intended for assessing both the quality of the surgery results as well as physical therapy progression. Criteria such as mobility, compact design, accuracy, repeatability, and ease of operation are some of the major requirements. The initial prototype is intended to collect FPL strength data to establish operating conditions.
PPARγ ligand production is tightly linked to clonal expansion during initiation of adipocyte differentiation (2014)

Adipocyte differentiation is orchestrated by the ligand-activated nuclear receptor PPARγ. Endogenous ligands comprise oxidized derivatives of arachidonic acid and structurally similar PUFAs. Although expression of PPARγ peaks in mature adipocytes, ligands are produced primarily at the onset of differentiation. Concomitant with agonist production, murine fibroblasts undergo two rounds of mitosis referred to as mitotic clonal expansion. Here we show that mouse embryonic fibroblasts deficient in either of two cell cycle inhibitors, the transcription factor p53 or its target gene encoding the cyclin-dependent kinase inhibitor p21, exhibit increased adipogenic potential. The antiadipogenic effect of p53 relied on its transcriptional activity and p21 expression but was circumvented by administration of an exogenous PPARγ agonist suggesting a linkage between cell cycling and PPARγ ligand production. Indeed, cell cycle inhibitory compounds decreased PPARγ ligand production in differentiating 3T3-L1 preadipocytes. Furthermore, these inhibitors abolished the release of arachidonic acid induced by the hormonal cocktail initiating adipogenesis. Collectively, our results suggest that murine fibroblasts require clonal expansion for PPARγ ligand production at the onset of adipocyte differentiation.
Photoelectron Spectroscopy Studies of the Functionalization of a Silicon Surface with a Phosphorylcholine-Terminated Polymer Grafted onto (3-Aminopropyl)trimethoxysilane (2006)

The structure of a biomimetic phosphorylcholine (PC)-functionalized poly(trimethylene carbonate) (PC-PTMC-PC), linked to a silicon substrate through an aminolysis reaction at 120 degrees C with (3-aminopropyl)trimethoxysilane (APTMS), was studied using photoelectron spectroscopy. Two chemical states were found for the unreacted APTMS amine, a neutral state and a protonated state, where the protonated amine on average was situated closer to the silicon substrate than the neutral amine. The experiments also indicated the presence of a third chemical state, where amines interact with unreacted silanol groups. The PTMC chains of the grafted films were found to consist of only 2-3 repeat units, with the grafted chains enriched in the zwitterionic end group, suggesting that these groups are attracted to the surface. This was further supported by the experiments showing that the PC groups were situated deeper within the film.
Interfering parameters in the determination of urinary globotriaosylceramide (Gb3) in patients with chronic kidney disease (2015)

The Gb3-24:18 isoform ratio is unaffected by several potential influencing variables and may thus be applied for screening for Fabry disease in unselected cohorts of patients presenting with CKD.
Tunable Fiber‐Cavity Enhanced Photon Emission from Defect Centers in hBN (2021)

Abstract Realization of quantum photonic devices requires coupling single quantum emitters to the mode of optical resonators. In this work, a hybrid system consisting of defect centers in few‐layer hexagonal boron nitride (hBN) grown by chemical vapor deposition and a fiber‐based Fabry–Pérot cavity is presented. The sub 10‐nm thickness of hBN and its smooth surface enable efficient integration into the cavity mode. This hybrid platform is operated over a broad spectral range larger than 30 nm and its tuneability is used to explore different coupling regimes. Consequently, very large cavity‐assisted signal enhancement up to 50‐fold and strongly narrowed linewidths are achieved, which is owing to cavity funneling, a record for hBN‐cavity systems. Additionally, an excitation and readout scheme is implemented for resonant excitation that allows to establish cavity‐assisted photoluminescence excitation (PLE) spectroscopy. This work marks an important milestone for the deployment of 2D materials coupled to fiber‐based cavities in practical quantum technologies.
Symmetrical Electrochromic and Electroemissive Devices from Semi-Interpenetrating Polymer Networks (2008)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Molecular decay rate near nonlocal plasmonic particles (2015)

When the size of metal nanoparticles is smaller than typically 10 nm, their optical response becomes sensitive to both spatial dispersion and quantum size effects associated with the confinement of the conduction electrons inside the particle. In this Letter, we propose a nonlocal scheme to compute molecular decay rates near spherical nanoparticles which includes the electron-electron interactions through a simple model of electronic polarizabilities. The plasmonic particle is schematized by a dynamic dipolar polarizability α(NL)(ω), and the quantum system is characterized by a two-level system. In this scheme, the light matter interaction is described in terms of classical field susceptibilities. This theoretical framework could be extended to address the influence of nonlocality on the dynamics of quantum systems placed in the vicinity of nano-objects of arbitrary morphologies.
