Intraseasonal predictability of the duration of flooding above National Weather Service flood warning levels across the U.S. Midwest (2020)

Abstract Unpreparedness is often the main cause of the economic and social damages caused by floods. To mitigate these impacts, short‐term forecasting has been the focus of several studies during the past decades; however, less effort has been paid to flood predictions at longer lead times. Here, we use forecasts by six models from the North American Multi‐Model Ensemble project with a lead time from 0.5 to 9.5 months to predict the seasonal duration of floods above four National Weather Service flood categories (“action,” “flood,” “moderate” and “major”). We focus on 202 U.S. Geological Survey gage stations across the U.S. Midwest and use a statistical framework which considers precipitation, temperature, and antecedent wetness conditions as predictors. We find that the prediction skill of the duration of floods for the “action” and “flood” categories is overall low, largely because of the low accuracy of the climate forecasts rather than of the errors introduced by the statistical models. The prediction skill slightly improves when considering the shortest lead times (i.e., from 0.5 to 2.5 months) during spring in the Northern Great Plains, where antecedent wetness conditions play an important role in influencing the generation of floods. It is very difficult to draw strong conclusions with respect to the “moderate” and “major” flood categories because of the limited number of available events.

Biotransformation of hexahydro‐1,3,5‐trinitro‐1,3,5‐triazine (RDX) by a prospective consortium and its most effective isolate Serratia marcescens (1997)

The biotransformation of hexahydro-1,3,5-trinitro-1,3,5 triazine (RDX) has been observed in liquid culture by a consortium of bacteria found in horse manure. Five types of bacteria were found to predominate in the consortium and were isolated. The most effective of these isolates at transforming RDX was Serratia marcescens. The biotransformation of RDX by all of these bacteria was found to occur only in the anoxic stationary phase. The process of bacterial growth and RDX biotransformation was quantified for the purpose of developing a predictive type model. Cell growth was assumed to follow Monod kinetics. All of the aerobic and anoxic growth parameters were determined: μmax, Ks, and Yx/s. RDX was found to competitively inhibit cell growth in both atmospheres. Degradation of RDX by Serratia marcescens was found to proceed through the stepwise reduction of the three nitro groups to nitroso groups. Each of these reductions was found to be first order in both component and cell concentrations. The degradation rate constant for the first step in this reduction process by the consortium was 0.022 L/g cells · h compared to 0.033 L/g cells · h for the most efficient isolate. © 1997 John Wiley & Sons, Inc.

Abstract 2125: Severity of Left Ventricular Dyssynchrony in Patients with Ischemic and Non-Ischemic Cardiomyopathy: a Cardiovascular Magnetic Resonance Tissue Synchronization Mapping Study (2007)

Aims: Studies on cardiac resynchronization therapy (CRT) for heart failure have shown a differential response in patients with ischemic (ICM) and non-ischemic cardiomyopathy (NICM). Increasing dyssynchrony has been shown to relate to a poor prognosis in patients with heart failure. We hypothesized that ICM and NICM have varying effects on left ventricular (LV) synchrony. Methods: The recently described cardiovascular magnetic resonance tissue synchronization index (CMR-TSI), which predicts benefit from CRT, was quantified in 181 patients (age: 66.4 ± 10.6 yrs, NYHA class III or IV, LVEF: 23.5 ± 10.8%, QRS = 139.8 ± 32.0 ms) with ICM (n=105) or NICM (n=76) and age-matched, healthy controls (n=24). The maximum time-to-peak radial wall motion in a short axis stack of LV images (steady-steady free precession imaging) was fitted to an empirical sine wave [y = a + b * sin (t/RR + c)]. The CMR-TSI was calculated as the SD of all segmental phase shifts of the radial wall motion extracted from this wave (see Figure for bull’s eye maps). Results: CMR-TSI was higher in ICM (105.8 ± 44.2, ANOVA p&lt;0.0001) and in NICM (68.1 ± 30.5, p&lt;0.0001) than in controls (22.5 ± 8.6) (see Figure ). In multivariate analyses including ICM and NICM patients only, ischemic aetiology emerged as a positive predictor of CMR-TSI, independent of QRS duration, LV end-systolic and end-diastolic volumes, and LVEF (all p&lt;0.0001). Conclusions: ICM is associated with a greater degree of dyssynchrony than NICM, independently of QRS duration, LV volumes and LVEF. These findings may account for the differential response to CRT observed with patients with ICM and NICM.
Proliferative response of mouse spermatogonial stem cells after irradiation: a quantitative model analysis of experimental data (1996)

The testes of CDF1 mice were irradiated with single doses of X-rays ranging from 2-16 Gy. The number of haploid cells in the testis at different times after irradiation (42-350 days) was determined by one-parameter flow cytometry both for irradiated animals and for age-matched controls. Based on literature data on the kinetics of the spermatogenesis in mice, a mathematical model of the (hierarchical) germ tissue was developed. Using this model, the processes of radiation-induced cell loss and subsequent recovery were simulated and free parameters of the model were estimated by fitting the model prediction to the experimental data. One of the aims of the study was to investigate the kinetic behaviour of spermatogonial stem cells and the corresponding control mechanisms. In order to fit the data, the model has to include the following features: (i) A preferential self-repopulation of spermatogonial stem cells following tissue injury. The model-estimated probability of a self-renewing division rises from 50% (the steady-state value) to 95% if the stem-cell population is reduced to 10% of its normal size. (ii) A relatively low, almost constant turnover rate of the stem-cell compartment. It is suggested by the analysis that less than 10% of the spermatogonial stem cells present in the testis divide per day, regardless of the degree of cellular depletion. (iii) A mechanism responsible for incomplete recovery. The observed incomplete recovery of spermatogenesis after single doses exceeding 10 Gy can be described quantitatively assuming that the stem cells are organized into discrete proliferative structures, the number of cells per structure being about 60.
Recrystallization of Oxygen Ion Implanted Ba 0.7 Sr 0.3 TiO 3 Thin Films (2000)

The crystallization behavior of chemical‐solution‐deposited and amorphous Ba 0.7 Sr 0.3 TiO 3 (BST) thin films was analyzed with respect to the evolution of the structural and dielectric properties of the films as a function of the annealing temperature. The amorphous films were produced by oxygen ion implantation into crystalline BST thin films. In the amorphous thin films, the crystallization to the perovskite phase occurred at T = 550°C, whereas the as‐deposited CSD films showed the first crystalline XRD‐reflex only after annealing at T = 650°C. Here a carbon‐rich intermediate phase delayed the crystallization process to higher temperatures.

Effect of pre-straining treatment on high temperature creep behavior of Ni-based single crystal superalloys (2019)

This study investigated a novel hypothesis on the influences of residual or pre-dislocation structures on creep life of Ni-based single crystal superalloys. Different types of anisotropic dislocation structures were created by pre-straining the samples at a relatively low temperature under different constant bias load conditions. After such pre-straining treatment, the samples were subjected to creep testing at higher temperatures under uniaxial tension. It was found that the pre-straining treatment was effective in creating different anisotropic dislocation structures without affecting the γ′ phase cuboid morphology and that the samples containing different anisotropic dislocation structures have all significantly reduced creep lives. The difference in the anisotropy of the dislocation structures has little influence on the reduction of the creep life or the rafting morphology of the γ′ phase cuboids. By using a Re-free alloy, the influence of the TCP phase precipitation on creep life is also clarified. These observations suggest that interruption to high temperature straining is the main contributor to the reduced creep lives. This finding raises a serious concern on the validity, or reliability, of creep life assessment based on continuous laboratory creep tests for real life applications, where the services are almost always interrupted into intermittent sessions. • Different anisotropic dislocation network structures were created by pre-straining at an elevated temperature. • The pre-existing anisotropic dislocation structures have no influence on the rafting behavior of the γ′ phase cuboids. • The pre-existing dislocations promote the formation of TCP phases during creep testing. • All pre-strained samples showed significantly reduced creep life.
&#x2208;SOA - Service Oriented Architectures adapted for embedded networks (2009)

The development of embedded networks poses several challenges: complexity and size of the network, heterogeneity of nodes, and infrastructure dynamics. From other IT domains it is known that many of these challenges can be met by a Service Oriented Architecture (SOA). In the context of embedded networks, an application can be interpreted as a set of interacting services that produce, consume or manipulate data. However, the hard boundary conditions of embedded networks, such as limited resources and real time requirements, have to be taken into account. This paper discusses an embedded SOA (eSOA) concept based on the definition of an embedded service (eService) term and the differences to traditional Web services based SOAs. The paper describes a middleware platform that supports the execution and development of embedded network applications by employing model based code generation and a pattern based service composition model. The advantages of the approach are showcased using an application from the building automation sector, focusing on the energy management of smart buildings.
Porphyrin Clips Derived from Diphenylglycoluril. Synthesis, Conformational Analysis, and Binding Properties (1999)

With the aim to construct synthetic systems that function according to the principles of enzymes, molecular clips based on diphenylglycoluril were covalently attached to (metallo)porphyrins. Two different porphyrin clips, 1 and 2, were synthesized that differ in the length and position of the linker between the clip and the porphyrin. This resulted in a great difference in flexibility of the cavity molecules, which had remarkable consequences for their binding properties in organic solution. The physical properties of the free base and zinc porphyrin clips have been studied in detail with NMR techniques and by the host−guest binding of viologen, dihydroxybenzene, and pyridine derivatives.
Improvement of anode lifetime by flushing during electrofiltration (2017)

The paper is focused on the influence of anode flushing on physicochemical conditions in the anode compartment and anode stability during the electrodewatering in electrofilter press. Kaolin suspensions were dewatered in laboratory filter press with stainless-steel electrodes at electric current density of 80 A/m2 and pressure of 2 bar. Two electrodewatering methods were compared: conventional (with filtrate drainage) and innovative (with continuous anode flushing using electrolyte solution). Flushing with neutral electrolyte solution significantly reduced the electrochemical anode corrosion, and can be suggested for the improvement of anode lifetime through a better control of physicochemical conditions during electrodewatering.
Computational sequence analysis of predicted long dsRNA transcriptomes of major crops reveals sequence complementarity with human genes (2013)

Long double-stranded RNAs (long dsRNAs) are precursors for the effector molecules of sequence-specific RNA-based gene silencing in eukaryotes. Plant cells can contain numerous endogenous long dsRNAs. This study demonstrates that such endogenous long dsRNAs in plants have sequence complementarity to human genes. Many of these complementary long dsRNAs have perfect sequence complementarity of at least 21 nucleotides to human genes; enough complementarity to potentially trigger gene silencing in targeted human cells if delivered in functional form. However, the number and diversity of long dsRNA molecules in plant tissue from crops such as lettuce, tomato, corn, soy and rice with complementarity to human genes that have a long history of safe consumption supports a conclusion that long dsRNAs do not present a significant dietary risk.
Novel carbon nanostructures prepared by solid-state pyrolysis of iron phthalocyanine (2006)

Solid-state pyrolysis of iron phthalocyanine in a sealed system was investigated for the preparation of carbon with novel nanostructures. Straight and highly aligned carbon nanotubes (CNTs) were obtained in bulk quantity. Higher temperatures (＞800℃) were beneficial to improve the growth of CNTs. By this procedure, long nanocables having an iron carbide core and a graphitic shell were fabricated. Carbon nanostructures with necklace-like and tube-in-tube architectures were prepared using this method.

This work considers the design of a microstrip antenna for 5 GHz frequency band along with different techniques that might be used for broadening of pass bandwidth. The microstrip antenna with pass bandwidth 17,6 % (at — 10 dB level of reflection index) and efficiency 61 % was designed.
Molecular interactions of Bcl-2 and Bcl-xL with mortalin: identification and functional characterization (2013)

Bcl-2 family of proteins consists of both pro-apoptotic and anti-apoptotic members that control cellular apoptosis. They predominantly reside in the mitochondria and control the release of apoptotic factors from the mitochondria to the cytosol by regulating its membrane potential and opening the PT (permeability transition) pore. Here we report bioinformatics and biochemical evidence to demonstrate the interaction between Bcl-2 and Bcl-xL with a stress chaperone, mortalin. We demonstrate that such interaction results in the abrogation of mortalin-p53 interaction leading to nuclear translocation and transcriptional reactivation of p53 function that results in an induction of senescence in cancer cells.
FG-MC-CDMA System Performance in Multi-band Channels (2008)

In this paper, we describe a generalized version of multicarrier CDMA (MC-CDMA) that extends to multiple frequency sub-bands or multiple bands. We term this frequency-generalized MC-CDMA (FG-MC-CDMA). This technique can provide more flexibility in selection of data rates and a larger diversity order than comparable schemes, by generalizing MC-CDMA to allow for different spreading factors. We describe the scheme's principles of operation, and provide analytical and simulation results for its use in multi-band channels. Our results show that FG-MC-CDMA can be an attractive transmission scheme for reliable multi-rate wireless communications.
Tauroursodeoxycholic acid binds to the G-protein site on light activated rhodopsin (2018)

The heterotrimeric G-protein binding site on G-protein coupled receptors remains relatively unexplored regarding its potential as a new target of therapeutic intervention or as a secondary site of action by the existing drugs. Tauroursodeoxycholic acid bears structural resemblance to several compounds that were previously identified to specifically bind to the light-activated form of the visual receptor rhodopsin and to inhibit its activation of transducin. We show that TUDCA stabilizes the active form of rhodopsin, metarhodopsin II, and does not display the detergent-like effects of common amphiphilic compounds that share the cholesterol scaffold structure, such as deoxycholic acid. Computer docking of TUDCA to the model of light-activated rhodopsin revealed that it interacts using similar mode of binding to the C-terminal domain of transducin alpha subunit. The ring regions of TUDCA made hydrophobic contacts with loop 3 region of rhodopsin, while the tail of TUDCA is exposed to solvent. The results show that TUDCA interacts specifically with rhodopsin, which may contribute to its wide-ranging effects on retina physiology and as a potential therapeutic compound for retina degenerative diseases.
Abstraction in algorithm animation (2003)

Abstraction of information into visual form plays a key role in the development of algorithm animations. The authors present a classification for abstraction as applied to algorithm animation. The classification emphasizes the expressive power of the abstraction ranging from simple direct presentation of the program's state to complex animations intended to explain the behavior of the program. They illustrate their classification by presenting several visualizations of a shortest path algorithm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Receptors that mediate cellular dependence (2005)

Cells depend for their survival on stimulation by trophic factors and other prosurvival signals, the withdrawal of which induces apoptosis, both via the loss of antiapoptotic signaling and the activation of proapoptotic signaling via specific receptors. These receptors, dubbed dependence receptors, activate apoptotic pathways following the withdrawal of trophic factors and other supportive stimuli. Such receptors may feature in developmental cell death, carcinogenesis (including metastasis), neurodegeneration, and possibly subapoptotic events such as neurite retraction and somal atrophy. Mechanistic studies of dependence receptors suggest that these receptors form ligand-dependent complexes that include specific caspases. Complex formation in the absence of ligand leads to caspase activation by a mechanism that is typically dependent on caspase cleavage of the receptor itself, releasing proapoptotic peptides. Cellular dependence receptors, considered in the aggregate, may thus form a system of molecular integration, analogous to the electrical integration system provided by dendritic arbors in the nervous system.
Gleason grade remains an important prognostic predictor in men diagnosed with prostate cancer while on finasteride therapy (2005)

Finasteride does not appear to compromise the assignment of Gleason grade for use in prediction tools before or after RP in men undergoing prostate biopsy or RP. The actuarial 5-year freedom from recurrence was similar to that predicted by the validated nomograms. Gleason grade remains an important prognostic predictor in men treated with finasteride and undergoing RP for clinically localized prostate cancer.
K-band Carbon Nanotube FET Operation (2006)

Measurements of the mixing products produced by two closely spaced microwave input signals applied to the gate of the FET circumvented the problems associated with measuring high impedance RF devices in 50 Omega systems. The frequency-independent performance of a CNT FET, at frequencies as high as 23 GHz, was demonstrated for the first time. This observed operating frequency represents a significant breakthrough in the realization of carbon nanotube-based electronics for high frequency applications
Optoelectronic relational algebraic processor (1991)

The dual scale topology optoelectronic processor (DSTOP) was developed for generalized matrix algebra. 1 Vector outer products are a particularly useful feature of the DSTOP architecture. Since the computation is performed electronically, a generalized function may be substituted for conventional numerical multiplication; this is especially useful in symbolic computations such as those required in relational databases. We have developed algorithms appropriate for DSTOP that use generalized outer products in the execution of relational algebraic operations. 2 The DSTOP processor serves as a decision subsystem in a relational database machine. The DSTOP relational algebraic processor is well suited to interface with 3D optical storage devices such as optical disks, photorefractive crystals or two-photon memories. The operations performed include joins, set difference, union, intersection and set division. Duplicate removal may also be performed in the support of the projection relational operator. The remaining relational operators, selection and Cartesian product, are not included. Cartesian products require no decision mechanism while selection, which is a unary operator, is best performed on a smaller, front end processor.
