Two-Beam Fluorescence Cross-Correlation Spectroscopy in an Electrophoretic Mobility Shift Assay (2002)

Two-beam fluorescence cross-correlation spectroscopy (FCCS) was used to resolve the bound and unbound fractions of fluorescently labeled single-stranded DNA (ssDNA) in a ssDNA-protein complex as the analyte solution flowed continuously through an electrophoresis capillary. Cross-correlation of the single molecule fluorescence from two spatially separate excitation laser beams resulted in cross-correlation functions that consisted of well-resolved peaks characteristic of the different electrophoretic flow velocities of the bound and unbound ssDNA. This decoupled the molecular parameters of the bound and unbound ssDNA used to model the cross-correlation function, which enabled the relative concentrations to be determined without prior knowledge of the pure-component cross-correlation functions, as would be required in an analogous autocorrelation analysis. The relative concentrations of the bound and unbound ssDNA were determined by two-beam FCCS within 2-6% precision, even for samples that contained as little as 5% unbound ssDNA, and were consistent with the results obtained by capillary electrophoresis (CE) separation of the same samples. Data sufficient to obtain these results was acquired in 10-15 s per sample. Fluorescently labeled poly(dT)39 complexed with the single stranded DNA binding protein of Escherichia coli served as the model system. The measured dissociation constant of 2.5+/-0.9 nM agreed with the literature value for this complex within experimental error. The CE/two-beam FCCS experiment described here is part of a family of techniques that use single molecule fluorescence detection to resolve different components in an electrophoresis system. Advantages of these methods relative to separations-based CE include enhanced sensitivity, the potential for higher speed analyses, elimination of the sample plug injection step, and the ability to carry out the analysis in shorter flow channels.
Multimodality imaging can predict the metabolic response of unresectable colorectal liver metastases to radioembolization therapy with Yttrium-90 labeled resin microspheres (2008)

Selective internal radiotherapy (SIRT) using Yttrium-90 labeled resin microspheres is increasingly used for the radioembolization of unresectable liver metastases of colorectal cancer (CRC). The treatment can be simulated by scintigraphy with Tc(99m)-labeled macroaggregates of albumin (MAA). The aim of the study was to develop a predictive dosimetric model for SIRT and to validate it by correlating results with the metabolic treatment response. The simulation of the dosimetry was performed by mathematically converting all liver voxel MAA-SPECT uptake values to the absolute Y(90) activity. The voxel values were then converted to a simulated absorbed dose (Gy) using simple MIRD formalism. The metabolic response was defined as the change in total lesion glycolysis (TLG) on FDG-PET. A total of 39 metastatic liver lesions were studied in eight evaluable patients. The mean administered Y(90) activity was 1.69 GBq (range: 1.33-2.04 GBq). The median (95% CI) simulated absorbed dose (Gy) was 29 Gy (1–98 Gy) and 66 Gy(32–159 Gy) in the poor (<50% TLG change) and the good responders (TLG change > 50%),respectively [DOSAGE ERROR CORRECTED].Using a simple cut-off value of 1 for the MAA-tumor-to-normal uptake ratio, a significant metabolic response was predicted with a sensitivity of 89% (17/19), a specificity of 65% (13/20), a positive predictive value of 71% (17/24) and a negative predictive value of 87% (13/15). Integrated multimodality imaging allows prediction of metabolic response post radioembolization using Y(90)-resin microspheres, and should be used for patient selection.
Direct interaction of Smn with dp103, a putative RNA helicase: a role for Smn in transcription regulation? (2000)

Spinal muscular atrophy is an autosomal recessive neurodegenerative disease of childhood, resulting from deletion or mutation of the survival motor neuron ( SMN ) gene on chromosome 5q13. SMN exists as part of a 300 kDa multi-protein complex, incorporating several proteins critically required in pre-mRNA splicing. Although SMN mutations render SMN defective in this role, the specific alpha-motor neuron degenerative phenotype seen in the disease remains unexplained. Here we demonstrate the isolation from mouse brain of the murine homologue of a recently identified novel RNA helicase of the DEAD box family, DP103, and its direct and specific binding of SMN. Previous work has shown that DP103 binds viral proteins known to interact with a cellular transcription factor to modulate gene expression. We suggest that the interaction between SMN and DP103 is further evidence for a role for SMN in transcriptional regulation and that SMN may be involved in the regulation of neuron-specific genes essential in neuronal development.
Finiteness conditions for fixed point iteration (1992)

This paper provides a link between the formulation of static program analyses using the framework of abstract interpretation (popular for functional languages and using the more classical framework of data flow anlysis (popular for imperative languages). In particular we show how the classical notions of fastness, rapidity and k -boundedness carry over to the abstract interpretation framework and how this may be used to bound the number of times a functional should be unfolded in order to yield the fixed point. This is supplemented with a number of results on how to calculate the bounds for iterative forms (as for tail recursion), for linear forms (as for one nested recursive call), and for primitive recursive forms. In some cases this improves the “worst case” results of, but more importantly it gives much better“average case” results.
Physical Fatigue Affects Gait Characteristics in Older Persons (2007)

Fatigue affects self-reported functioning in older persons. Balance and gait problems increase fall risk. The effect of physical fatigue in the elderly population in general, and on balance control during walking in particular is not well known. This study investigates how a repeated sit-to-stand task affects gait control in older persons.Twenty-two persons (mean age 78 years) took part in a fatigue group (FG), and 22 persons (mean age 80 years) in a matched control group (CG). Participants walked back and forth on a walkway at different walking speeds. Gait data were adjusted for pretest-posttest differences in walking speed. The FG participants were physically fatigued by a repeated sit-to-stand task. Trunk data were obtained by a triaxial accelerometer and foot level data by an electronic walkway.There were no group differences in preferred gait speed (p =.96) or in step length (p =.47) following the fatiguing task, but there were significant increases in step width (p =.023) and in mediolateral trunk acceleration amplitude (p =.038) in the FG group. Step-length variability (p =.004) and interstride trunk acceleration variability in the vertical direction (p =.002) increased, and tended to increase in the anteroposterior direction (p =.10) and to decrease in the mediolateral direction (p =.10) in the FG only.Gait changes following a physical fatiguing task agree with changes previously found in older persons at risk of falling, suggesting that physical fatigue may represent a risk factor for falls in elderly persons.
A Comparison of Healthy, Ocular Hypertensive, and Glaucomatous Optic Disc Topographic Parameters (1997)

Ocular hypertensive optic discs (with a clinically normal appearance) could not be distinguished from healthy discs using a confocal scanning laser ophthalmoscopic technique. Glaucomatous optic discs were found to differ from both healthy and OH discs, with a limited effect of disc size.

FeCl<sub>3</sub> Catalyzed Prins-Type Cyclization for the Synthesis of Highly Substituted Indenes: Application to the Total Synthesis of (±)-Jungianol and <i>epi</i>-Jungianol (2013)

A novel approach was developed for the synthesis of highly substituted indene derivatives, using an FeCl(3) catalyzed Prins-type cyclization reaction which was further applied in the total synthesis of jungianol and epi-jungianol.
The transcription factors hypoxia‐inducible factor 1α and Ets‐1 colocalize in the hypoxic synovium of inflamed joints in adjuvant‐induced arthritis (2004)

Our results demonstrate the presence of hypoxia in inflamed joints in this experimental model of arthritis. The colocalization of Ets-1 and HIF-1alpha in these hypoxic areas suggests that hypoxia may induce Ets-1 and HIF-1alpha expression during joint inflammation.
Performance of ARQ and NAK-based ARQ on a correlated fading channel (2003)

Acknowledgment messages in conventional ARQ operations include both ACK and NAK (ACK/NAK-based ARQ). In NAK-based ARQ, there is no ACK message. This paper examines the difference between the two ARQ approaches, presenting performance comparisons in terms of throughput and delay. Both random error channel and correlated fading channel are considered. The impact of a noisy feedback channel is also investigated.
Implementation and Design of Fuzzy ID3 to Forecast Seasonal Runoff (2013)

ndian agriculture includes a mix of traditional to modern farming techniques. In some parts of India, traditional use of cattle to plough farms remains in use. Traditional farms have some of the lowest per capita productivities and farmer incomes. Slow agricultural growth is a concern for policymakers as some two-thirds of India's people depend on rural employment for a living. Current agricultural practices are neither economically nor environmentally sustainable and India's yields for many agricultural commodities are low. Poorly maintained irrigation systems and almost universal lack of good extension services are among the factors responsible. Farmers' access to markets is hampered by poor roads, rudimentary market infrastructure, and excessive regulation. This paper will be developed by me, a hybrid forecasting technique that is mixture of fuzzy logic and ID3 data mining algorithm. That forecast seasonal runoff on the basis of every day whether conditions. Moreover it to get the authenticity of the system we compare the system with a traditional ID3 based system. Keywordslogic, ID3, water supply, forecast.
Automatic PLC Code Generation Based on Virtual Engineering Model (2019)

Today's automotive firms, regardless the systems they use (e.g. mass production, mass customisation, just-in-time, etc.) face common challenges that can result in sudden and frequent disruptions across the supply chain. Manufacturing systems should rapidly respond to these disruptions. This can be made possible by introducing new smart engineering methods and technologies to enable realisation of high level of reconfigurable and dynamic manufacturing processes to improve the overall performance of manufacturing plants. This paper investigates a methodology to develop a digital model for a fuel-cell assembly system and then utilises the developed model to automatically generate machine's Programmable Logic Controller (PLC) code, connectivity, and process data records. These automatically generated parts can then be used in order to create a Cyber Physical System (CPS). The aim of this paper is to demonstrate the automatic generation of the control code and structure it in order to be effectively and efficiently used in industrial applications. The on-going DIGIMAN project [1], which aims to deliver a proof of process fuel-cell assembly system for the automotive industry, is being used as a proof of concept to validate the proposed methodology and framework.
Quantum transport in Dirac materials: Signatures of tilted and anisotropic Dirac and Weyl cones (2015)

We calculate conductance and noise for quantum transport at the nodal point for arbitrarily tilted and anisotropic Dirac or Weyl cones. Tilted and anisotropic dispersions are generic in the absence of certain discrete symmetries, such as particle-hole and lattice point group symmetries. Whereas anisotropy affects the conductance $g$, but leaves the Fano factor $F$ (the ratio of shot noise power and current) unchanged, a tilt affects both $g$ and $F$. Since $F$ is a universal number in many other situations, this finding is remarkable. We apply our general considerations to specific lattice models of strained graphene and a pyrochlore Weyl semimetal.
Detecting Spammers on Twitter (2010)

Episodic vasomotor instability with flushing is an uncommon presentation that is suggestive of an endocrine etiology. This report is the case of a 42-year-old woman who presented to the ED 5 times in a 2-week period for recurrent, self-limited episodes of light-headedness associated with tachycardia, hypertension, and flushing. The patient's diagnosis eluded detection in both the outpatient and the inpatient settings for several months. The clinical diagnosis was ultimately confirmed by biochemical test samples obtained in the ED during a subsequent symptomatic event. The differential diagnosis of this patient's presentation includes pheochromocytoma, carcinoid syndrome, medullary thyroid carcinoma, systemic mastocytosis, and other endocrine and toxicologic diseases. ED management of the patient with transient yet significant vasomotor changes includes a workup for syncope, initiation of focused biochemical investigations, referral to the appropriate consultant, and consideration for admission.
Putting Passives in Their Place (2003)

The next big thing in miniaturization is integrating resistors, capacitors, and inductors into circuit boards. These integrated passives would be a part of the circuit board itself, formed when the board was, so their overall cost would eventually be less than what manufacturers pay at present to buy and solder attach discrete devices. This article examines the advantages of this integration scheme, and looks at the difficulties involved.
Changing Patterns of Anal Cancer Incidence in the United States, 1940‐1989 (1994)

Anal cancer has been hypothesized to be associated with a sexually transmitted agent and, more recently, with the epidemic of human immunodeficiency virus (HIV). The authors used a descriptive incidence study to evaluate these hypotheses based on US data from the Surveillance, Epidemiology, and End Results (SEER) program for 1973-1989 and from the Connecticut Tumor Registry for 1940-1988. Since 1960, anal cancer incidence in Connecticut increased 1.9-fold among men and 2.3-fold among women. Based on information from SEER, the incidence was lowest among white men (1973-1989 average: 0.41/100,000) and highest among black women (1973-1989 average: 0.74/100,000). Residents of the metropolitan areas had a twofold risk of anal cancer compared with populations in less densely populated areas. The most dramatic change in incidence was observed for white men in the San Francisco Bay area, among whom the incidence increased from 0.5/100,000 in 1973-1975 to 1.2/100,000 in 1988-1989 (p trend < 0.001). The relative risks (95% confidence intervals) of anal cancer among never married men compared with ever married men in the urban areas rose from 5.8 (0.9-8.7) in 1973-1978 to 6.7 (4.7-9.5) in 1979-1984 and 10.3 (7.5-14.1) in 1985-1989 (p trend = 0.02). No significant difference was observed among women. In conclusion, anal cancer incidence in the United States has increased significantly during the past 30 years and is now higher in women than men, in blacks than whites, and in residents of metropolitan rather than rural areas. Some of this changing pattern clearly relates to the period prior to the acquired immunodeficiency syndrome (AIDS) epidemic and argues that behavioral changes are important in anal cancer development. However, the recent remarkable change in rates among never married men and men living in the San Francisco Bay area suggests that homosexual men are at special and increasing risk. The authors speculate whether part of this recent increase could be attributed to the AIDS epidemic.
CBAS: A CNN-based biometrics authentication system (2010)

Biometric identification is an important security application that requires non-intrusive capture and real-time processing. Security systems based on fingerprints and retina patterns have been widely developed, but can be easily falsified. Recently, identification by vein patterns has been practiced as a promising alternative. The paper presents a CNN-based system, realized on an FPGA that is able to perform all three recognition methods. The focus is on the vein recognition algorithm whose detection quality is sufficient for person identification but scalable for authentication.
Tourniquet occlusion technique for lower extremity artery reconstruction in war wound. (1997)

Reconstruction of blood vessels after war injuries is mandatory for life and limb salvage. In an effort to prevent prolonged major bleeding and make reconstruction quicker and technically more comfortable, thigh pneumatic tourniquet occlusion was performed pre- and intraoperatively in eleven of 53 wounded with injuries of the arteries of the lower extremities during 1991/92 war against Croatia at the Department of Surgery, Osijek Clinical Hospital. This method benefits life and limb salvage under war conditions.
Remote sensing of surface and near surface temperature from remotely piloted aircraft (1985)

Surface temperature and atmospheric temperature near the surface may be estimated through a method that uses data from common types of airborne thermal infrared imager or other radiometric device having a narrow field of view. The method accounts for effects of atmospheric attenuation, surface emissivity, reflected cloud and clear sky radiance, and sensor response to various levels of approximation. Required meteorological measurements are the temperature of the intervening atmosphere and possibly the cloud base. Data acquired by other investigators suggest accuracies approaching ±1 K for certain surfaces such as water and that similar accuracies in atmospheric temperature may be expected for certain vegetated surfaces.
Blends of high density polyethylene with branched poly(styrene‐<i>co</i>‐dodecyl acrylate): Rheological, mechanical, and thermal properties (2008)

Abstract Branched poly(styrene‐ co ‐dodecyl acrylate) (BPSDA) was prepared by the atom transfer radical copolymerization of styrene with dodecyl acrylate using p ‐cholomethyl styrene as initiator‐monomer (inimer) and CuCl/Bpy (2,2′‐bipyridine) complex as catalyst. The remarkable discrepancies between the molecular weight determined by gel permeation chmotagraphy and multiangel laser light scattering reveals the highly branched structure of the resulting copolymer. Furthermore, the composition was analyzed by hydrogen nuclear magnetic resonance ( 1 H NMR), which is consistent with the feed ratio of monomers. Blending of the branched product with high density polyethylene (HDPE) was attempted in haake mixer. The rheological, mechanical, and thermal stability properties of the resulting blends were studied. Compared with pure HDPE, the complex viscosity of blend with addition of 4 wt % BPSDA decreased by 15.9%. While the elongation at break decreased by 5.5% and tensile strength decreased by 4.2%. SEM (scanning electron microscopy) revealed that the average particle size of disperse phase in HDPE/4% BPSDA blend is 0.45 μm in diameter. Differential scanning calorimetry characterization showed that the addition of BPSDA accelerated the relative crystallization rate but decreased the final absolute degree of crystallinity. No obvious change of thermal stability of the blends was observed relative to pure HDPE. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Forced convection heat transfer for two-phase helical flow in a solar receiver (1981)

The heat transfer characteristics of a single-tube, helically coiled receiver for a concentrating solar collector are presented. Heat transfer coefficients were measured for single- and two-phase water-steam flow in a helical coil subjected to radiant heating for a range of flow conditions and radiant flux levels. Results are presented for both the local and average heat transfer coefficients in several flow regimes and the results correlated with non-dimensional, geometric, fluid, and flow parameters. 9 refs.
A New Adaptive Digital Audio Watermarking Based on Support Vector Regression (2007)

On the basis of support vector regression (SVR), a new adaptive blind digital audio watermarking algorithm is proposed. This algorithm embeds the template information and watermark signal into the original audio by adaptive quantization according to the local audio correlation and human auditory masking. The procedure of watermark extraction is as follows. First, the corresponding features of template and watermark are extracted from the watermarked audio. Then, the corresponding feature of template is selected as training sample to train SVR and an SVR model is returned. Finally, the actual outputs are predicted according to the corresponding feature of watermark, and the digital watermark is recovered from the watermarked audio by using the well-trained SVR. Experimental results show that our audio watermarking scheme is not only inaudible, but also robust against various common signal processing (such as noise adding, resampling, requantization, and MP3 compression), and also has high practicability. In addition, the algorithm can extract the watermark without the help of the original digital audio signal, and the performance of it is better than other SVM audio watermarking schemes.
