A human immune dysregulation syndrome characterized by severe hyperinflammation with a homozygous nonsense Roquin-1 mutation (2019)

Hyperinflammatory syndromes are life-threatening disorders caused by overzealous immune cell activation and cytokine release, often resulting from defects in negative feedback mechanisms. In the quintessential hyperinflammatory syndrome familial hemophagocytic lymphohistiocytosis (HLH), inborn errors of cytotoxicity result in effector cell accumulation, immune dysregulation and, if untreated, tissue damage and death. Here, we describe a human case with a homozygous nonsense R688* RC3H1 mutation suffering from hyperinflammation, presenting as relapsing HLH. RC3H1 encodes Roquin-1, a posttranscriptional repressor of immune-regulatory proteins such as ICOS, OX40 and TNF. Comparing the R688* variant with the murine M199R variant reveals a phenotypic resemblance, both in immune cell activation, hypercytokinemia and disease development. Mechanistically, R688* Roquin-1 fails to localize to P-bodies and interact with the CCR4-NOT deadenylation complex, impeding mRNA decay and dysregulating cytokine production. The results from this unique case suggest that impaired Roquin-1 function provokes hyperinflammation by a failure to quench immune activation.

'Race', Housing and Social Exclusion (1998)

Abstract The paper begins with an overview of the ways in which the concept of 'social exclusion' has been employed in both academic and political and media discourse. In the context of 'race' and housing, the term is most often seen in debates about inequalities between majority and minority communities. These inequalities form the basis of the next two sections of the paper: the first dealing with the national evidence, the second with a case study of Bradford District. The paper then looks at how the academic literature has traditionally theorised these inequalities, and asks whether the exclusion paradigm adds anything of value to these debates. It is concluded that whilst the concept may well be of use in drawing attention in policy circles to questions of inequality, it is rather less worthwhile in the context of sociological debates. It has tended to be used in numerous disparate senses thus potentially obscuring (rather then clarifying) issues, is little more than a descriptive label, and has lent itself to a form of sloganeering which may stifle rather than encourage debate.
Ionospheric Scintillation Effects on GPS Receivers during Solar Minimum and Maximum (2007)

The ionosphere has practical importance in GPS (Global Positioning System) applications because it influences transionospheric radio wave propagation. Among various phenomena in the ionosphere, ionospheric scintillation is characterized by rapid fluctuation and fading of the received signal intensity due to electron density irregularity inside the ionosphere. Deep signal fading caused by scintillation can lead to loss of lock of the carrier tracking loop in GPS receivers. The aircraft navigation system based on GPS and WAAS (Wide Area Augmentation System) uses code and carrier phase data to create the position estimate. If a significant number of carrier tracking channels lose lock simultaneously, the system cannot provide service until reacquiring a sufficient number of channels. Although scintillation is not frequent in the mid-latitude region, it is a potential hazard in terms of availability and continuity of the service in the equatorial region [1].
Wear and Why? How Ash Elements Can Help Define Wear Profiles of Biomass Feedstocks (2019)

<b><sc>Abstract.</sc></b> Biomass feedstocks have been shown to cause high wear rates on biomass processing equipment, including grinders, pneumatic conveyance systems, and screw feeders. Previously, wear rates were positively correlated with ash concentrations. Physical and chemical properties, including ash content, vary across the anatomy of plants in biomass feedstocks. To better understand biomass tissues that cause the most wear, anatomical fractions of pine forest residues were tested for wear properties. Fractions were tested in the Accelerated Wear Testing Apparatus using steel coupon mass loss to evaluate wear rates. Extrinsic ash was extracted and characterized. Total ash content of the forest residue was 0.80wt%. Anatomical fractions showed varied amounts of ash with highest concentrations in bark and needles (2.33wt%, 3.52wt%, respectively). The wear rate of the forest residue was 2.36mg loss per kg biomass. Low ash fractions, including whitewood and cambium, caused little wear. Bark had lower ash than the needles but resulted in more wear (8.63 vs 5.57mg loss per kg biomass). Bark contained the most extrinsic ash and largest ash particle size, while needles contained the least extrinsic ash and smallest ash particle size. These findings indicate that total ash content (intrinsic plus extrinsic), soil contamination, and elemental analysis can provide information related to wear properties of biomass materials; however, these analyses do not fully explain the differences observed in the wear rates of bark and needles. Additional testing is to determine other parameters of importance.
Effect of Selected Insecticides on Beneficial Insects and Spiders in Cotton, 1983 (1985)

Abstract ‘Lockett 77’ was planted on 3 Jun at the Texas Agricultural Experiment Station, Chillicothe, Texas in Portales clay loam soil that had been treated with Treflan. Seeding rate was 17.9 kg/ha in excellent soil moisture. A side dressing of nitrogen at 56.0 kg/ha was applied on 8 Jul. Furrow irrigations were made on 28 Jul and 11 Aug. Six insecticide treatments were replicated 4 times in a randomized complete block design. Plots were 12 rows wide and 24.4 m long, and there was 102 cm between rows. Alleys separating replications were 7.6 m wide. Treatments were applied on 29 Aug with a John Deere 6000 Hi-Cycle ground sprayer with drop nozzles added which gave 3 Teejet TX12 nozzles per row. Ground speed was 4.9 km/h delivering 76.7 liters/ha total solution at 275 kPa. Rainfall from planting to end of sampling was 89.9 mm, 52.1 mm, 6.9 mm and 0.0 mm for Jun, Jul, Aug, and Sep, respectively. Beneficial insects were collected utilizing a standard insect sweep net with 50 sweeps being taken in each plot. Beneficials were bagged, taken to the laboratory and counted.
A novel hollow fiber membrane‐assisted antisolvent crystallization for enhanced mass transfer process control (2018)

Herein, a novel hollow fiber membrane‐assisted antisolvent crystallization (MAAC) was proposed to enhance the mass transfer control over the antisolvent crystallization. A polyethersulfone membrane module was introduced as the key device for antisolvent transfer and solution mixing. An antisolvent liquid film layer was formed on the membrane surface and mixed with the solution. The liquid film also prevented the membrane from directly contacting with crystallization solution. By controlling both the shell side flow velocity and the antisolvent transfer, the antisolvent permeation rate achieved sensitive, stable, and accurate control during long‐term and repeated utilization. The interfacial mass transfer rate of MAAC was 0.66 mg cm −2 s −1 , which was only 1/50 that of conventional droplet antisolvent crystallization. MAAC also provided crystal products with better morphologies and narrower size distributions than the conventional process. The stable performances of MAAC in terms of its accurate antisolvent mass transfer and antifouling capabilities were also highlighted. © 2018 American Institute of Chemical Engineers AIChE J , 65: 734–744, 2019
Assessment of a Bleeding Risk Index in Two Cohorts of Patients Treated with Oral Anticoagulants (1996)

In two cohorts of patients on oral anticoagulant therapy, routinely treated by the Leiden Thrombosis Service, the frequency of major bleeding complications was assessed during two years (1988 and 1991). With Poisson regression analysis the influence of the risk factors age, sex, target zone, achieved INR and type of coumarin derivative used were determined. Subsequently, a bleeding risk index was calculated, combining the results of the two cohorts. For various types of patients the relative risk of major bleeding complications was assessed. Age and achieved INR were the most important and consistent risk factors: rate ratio (RR) for age in 1988 1.46 per 10 years increase (95% confidence interval [CI] 1.20-1.78) and in 1991 1.57 per 10 years increase (95% CI 1.23-2.00); RR per unit increase in achieved INR in 1988 1.42 (95% CI 1.21-1.68) and in 1991 1.44 per unit increase in achieved INR (95% CI 1.18-1.74). Two methods were used to combine the results of 1988 and 1991. In the first method the mean bleeding risk index was calculated: In (incidence) [natural logarithm of the incidence rate of major bleeding] = -5.64+ 0.42 * age +0.26 * sex -0.29 * target range +0.36 * achieved INR -0.36 * coumarin type. In the second method only the consistent risk factors age and achieved INR were used: In (incidence) = -5.64 -0.42 * age +0.36 * achieved INR. These bleeding risk indexes can be used to assess the risk of major bleeding complications of individual patients and allow more individualized care by individual tailoring the desired anticoagulation.
Metabolite Identification via LC‐SPE‐NMR‐MS of the In vitro Biooxidation Products of a Lead mGlu5 Allosteric Antagonist and Impact on the Improvement of Metabolic Stability in the Series (2007)

Detailed information on the metabolic fate of lead compounds can be a powerful tool for an informed approach to the stabilization of metabolically labile compounds in the lead optimization phase. The combination of high performance liquid chromatography (HPLC) with nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) has been used to give comprehensive structural data on metabolites of novel drugs in development. Recently, increased automation and the embedding of on-line solid-phase extraction (SPE) into a integrated LC-SPE-NMR-MS system have improved enormously the detection limits of this approach. The new technology platform allows the analysis of complex mixtures from microsome incubations, combining low material requirements with relatively high throughput. Such characteristics make it possible to thoroughly characterize metabolites of selected compounds at earlier phases along the path to lead identification and clinical candidate selection, thus providing outstanding guidance in the process of eliminating undesired metabolism and detecting active or potentially toxic metabolites. Such an approach was applied at the lead identification stage of a backup program on metabotropic glutamate receptor 5 (mGlu5) allosteric inhibition. The major metabolites of a lead 5-aminothiazole-4-carboxylic acid amide 1 were synthesized and screened, revealing significant in vitro activity and possible involvement in the overall pharmacodynamic behavior of 1. The information collected on the metabolism of the highly active compound 1 was pivotal to the synthesis of related compounds with improved microsomal stability.
Energy-conserving selective repeat ARQ protocols for wireless data networks (2002)

Mobile communications implies reliance on a self-contained, portable power source, error-prone fading radio channels and subsequent need for acknowledgments. We propose two energy-conserving variants of the selective repeat ARQ protocol, which reduce the number of acknowledgments sent by the mobile node. The protocols are compared to previously described energy-conserving go-back-N ARQ protocols as well as classical approaches and shown to maintain favorable delay and throughput performances.
HIV-1 infected mononuclear phagocyte secretory products affect neuronal physiology leading to cellular demise: relevance for HIV-1-associated dementia. (2000)

Viral and cellular products from HIV-1-infected and/or immune competent mononuclear phagocytes (MP) (brain macrophages and microglia) affect neuronal function during HIV-1-associated dementia (HAD). Neurotoxic MP factors include, but are not limited to, pro-inflammatory cytokines, chemokines, platelet activating factor, arachidonic acid and its metabolites, nitric oxide, progeny virions and viral structural and regulatory proteins. The mechanisms for immune-mediated neural injury in HAD, only now, are being unraveled. In this regard, we reviewed the current knowledge of how postmitotic neurons, which can neither divide nor be replaced, are damaged by MP secretory activities. Linking neuronal function with brain MP activation was made possible by placing viral and/or immune products onto neurons and measuring cell signaling events or through ex vivo electrophysiological tests on MP-treated brain slices. Such linkages are shown, in this report, by select demonstrations of MP factors which cause neuronal dysfunction in HAD.

Therapeutic Applications of Antiflammin Peptides in Experimental Ocular Inflammation (2000)

Antiflammins are synthetic peptides derived from the region of highest local similarity between uteroglobulin and lipocortin. These peptides have shown anti-inflammatory activity on carrageenan-induced rat footpad edema. They are potent inhibitors for phospholipase A2 activation both in vitro and in vivo. Previously, we have demonstrated the effectiveness of topical antiflammins in suppressing acute ocular inflammation and allergic response in rodent endotoxin-induced uveitis and murine allergic conjunctivitis. The mechanisms by which antiflammins protect against inflammation and allergy in these ocular models may involve inhibition of phospholipase A2 and inducible nitric oxide synthase (iNOS) as well as the production of proinflammatory cytokine, interleukin-6.
Nanocrystalline Lithium Manganese Oxide Spinel Cathode for Rechargeable Lithium Batteries (2001)

Nanocrystalline lithium manganese oxide spinel (LMOS) has been prepared by ballmilling LMOS powders prepared by solid-state reaction. X-ray diffraction and transmission electron microscopy showed that significant strain was introduced and nanometer-scale grains were generated in the spinel particles. The ballmilled spinel cathodes exhibited excellent cyclability in the 3 V range at room temperature and at elevated temperatures in spite of an apparent Jahn-Teller distortion; stable discharge capacities in the 3 V range of 2.4 to 3.4 V at a current density of were ca. 125 and 150 mAh/g at room temperature and respectively. © 2001 The Electrochemical Society.

Sequential Hemofiltration- Hemodiafiltration Technique: All in One? (2005)

Sequential dialysis techniques (i.e. pure ultrafiltration followed by dialysis) have been used in the past, due to their capability to remove large volumes of fluids without inducing hemodynamic instability. The disadvantages of the inadequate dialysis and the lack of technology lead to the decline such methods. Hemofiltration (HF) and hemodiafiltration (HDF) are recently being utilized in a greater proportion thanks to the on line fluid preparation systems. Each process (HF and HDF) has its own benefits in the removal of small, medium and high-molecular weight substances and in the hemodynamic stability. Sequential hemofiltration/ hemodiafiltration (SHF/HDF), may combine the benefits and eliminate the disadvantages of each method. Furthermore they can be easily applied nowadays, due to the development of new high technological hemodialysis machines. In order to evaluate the feasibility and the effects of SHF/HDF we studied 7 chronic hemodialysis patients (6 months of treatment with SHF/HDF switched to 6 months of SHDF/HF), using the same machine (AK200 ULTRA), with on line fluid preparation system and the same type of dialyzer (Polyflux 210). The feasibility of such techniques (SHF/HDF or vice versa) resulted excellent. All sessions left the patients in a condition of well-being making fulltime work. No difference was observed between the different period of treatment, but a reduction in pre value was observed in calcium-phosphorous product, C-reactive protein and beta2-microglobulin, at the end of the sequential techniques. SHF/HDF therapy is a very promising technique. Further studies are needed to better explore the potential of such a therapeutic approach in the quality of life, the hemodialysis adequacy and the hemodynamic stability of our patients.
<title>Simulating atmospheric free-space optical propagation: rainfall attenuation</title> (2002)

With recent advances and interest in Free-Space Optics (FSO) for commercial deployments, more attention has been placed on FSO weather effects and the availability of global weather databases. The Meteorological Visual Range (Visibility) is considered one of the main weather parameters necessary to estimate FSO attenuation due to haze, fog and low clouds. Proper understanding of visibility measurements conducted throughout the years is essential. Unfortunately, such information is missing from most of the databases, leaving FSO players no choice but to use the standard visibility equation based on 2% contrast and other assumptions on the source luminance and its background. Another challenge is that visibility is measured using the visual wavelength of 550 nm. Extrapolating the measured attenuations to longer infrared wavelengths is not trivial and involves extensive experimentations. Scattering of electromagnetic waves by spherical droplets of different sizes is considered to simulate FSO scattering effects. This paper serves as an introduction to a series of publications regarding simulation of FSO atmospheric propagation. This first part focuses on attenuation due to rainfall. Additional weather parameters, such as rainfall rate, temperature and relative humidity are considered to effectively build the rain model. Comparison with already published experimental measurement is performed to validate the model. The scattering cross section due to rain is derived from the density of different raindrop sizes and the raindrops fall velocity is derived from the overall rainfall rate. Absorption due the presence of water vapor is computed using the temperature and relative humidity measurements.
Time–thermo-dynamics of anti-Stokes and Stokes scattering and luminescence in 1-nm silicon nanoparticles: Toward an optical nanorefrigerator (2022)

The thermodynamics of nanosystems is interesting, as they constitute the transition between the atomistic and solid states. This is empowered by the development of tools to manipulate individual atoms and perform atomistic simulations and fundamental thermos-science, such as microscopic time-symmetry and macroscopic time-asymmetry, the origin of time’s arrow, and photo-cryo-refrigeration. We examine here the photo-thermo and time dynamics in 1-nm silicon nanoparticles with tetrahedral-molecular core–shell structure prepared ex situ and suspended in solvents or re-constituted in films. We examined the temperature dependence of the quantum efficiency and time-dynamics of the Stokes luminescence and its energy dependence across the band. With temperature, we get flat lifetimes but with delay in the onset in agreement with a model calculation of above barrier emission. Our atomistic time-dependent density functional theory shows that Stokes heating takes place in the molecular-like shell where the lifetime is in the nanosecond regime, whereas anti-Stokes cooling takes place in the tetrahedral core where the lifetime is in the ms regime. Unlike doped glasses, we observed a 2-order of magnitude increase in the quantum efficiency of the Stokes luminescence at 10° K. The increase in the quantum efficiency at low temperature, the high quantum efficiency of stimulated anti-Stokes scattering and its anti-correlation with the luminescence, and the visible transparency/blindness due to quantum confinement are requirements for solid state photo-cooling, which may afford an all-silicon photo-cryo-refrigeration, with potential full integration into the CMOS silicon industry.
Generation of a multi‐functional, target organ‐specific, anti‐fibrotic molecule by molecular engineering of the extracellular matrix protein, decorin (2018)

Extracellular matrix (ECM) molecules play important roles in regulating processes such as cell proliferation, migration, differentiation and survival. Decorin is a proteoglycan that binds to ('decorates') collagen fibrils in the ECM. Decorin also interacts with many growth factors and their receptors, the most notable of these interactions being its inhibitory activity on TGF-β, the growth factor responsible for fibrosis formation. We have generated a recombinant, multi-functional, fusion-protein consisting of decorin as a therapeutic domain and a vascular homing and cell-penetrating peptide as a targeting vehicle. This recombinant decorin (CAR-DCN) accumulates at the sites of the targeted disease at higher levels and, as a result, has substantially enhanced biological activity over native decorin. CAR-DCN is an example of how molecular engineering can give a compound the ability to seek out sites of disease and enhance its therapeutic potential. CAR-DCN will hopefully be used to treat severe human diseases. LINKED ARTICLES: This article is part of a themed section on Translating the Matrix.

Visual Analysis of High-Dimensional Event Sequence Data via Dynamic Hierarchical Aggregation (2019)

Temporal event data are collected across a broad range of domains, and a variety of visual analytics techniques have been developed to empower analysts working with this form of data. These techniques generally display aggregate statistics computed over sets of event sequences that share common patterns. Such techniques are often hindered, however, by the high-dimensionality of many real-world event sequence datasets which can prevent effective aggregation. A common coping strategy for this challenge is to group event types together prior to visualization, as a pre-process, so that each group can be represented within an analysis as a single event type. However, computing these event groupings as a pre-process also places significant constraints on the analysis. This paper presents a new visual analytics approach for dynamic hierarchical dimension aggregation. The approach leverages a predefined hierarchy of dimensions to computationally quantify the informativeness, with respect to a measure of interest, of alternative levels of grouping within the hierarchy at runtime. This information is then interactively visualized, enabling users to dynamically explore the hierarchy to select the most appropriate level of grouping to use at any individual step within an analysis. Key contributions include an algorithm for interactively determining the most informative set of event groupings for a specific analysis context, and a scented scatter-plus-focus visualization design with an optimization-based layout algorithm that supports interactive hierarchical exploration of alternative event type groupings. We apply these techniques to high-dimensional event sequence data from the medical domain and report findings from domain expert interviews.
