<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In this paper, we demonstrate postprocessing techniques to adjust the threshold voltage ( <formula formulatype="inline"><tex Notation="TeX">$V_{t}$</tex></formula>) and on–off ratio (<formula formulatype="inline"><tex Notation="TeX"> $I_{{ON}}/I_{{OFF}}$</tex></formula>) of multiple-tube carbon nanotube field effect transistors (CNFETs). These postprocessing techniques open up an additional degree of freedom to further tune individual CNFETs in addition to various device synthesis and processing techniques. We demonstrate proof-of-concept experiments and fully characterize their design spaces and tradeoffs.

Detection of ventricular premature beats based on the pressure signals of a hemodialysis machine (2017)

Monitoring of ventricular premature beats (VPBs), being abundant in hemodialysis patients, can provide information on cardiovascular instability and electrolyte imbalance. In this paper, we describe a method for VPB detection which explores the signals acquired from the arterial and the venous pressure sensors, located in the extracorporeal blood circuit of a hemodialysis machine. The pressure signals are mainly composed of a pump component and a cardiac component. The cardiac component, severely overshadowed by the pump component, is estimated from the pressure signals using an earlier described iterative method. A set of simple features is extracted, and linear discriminant analysis is performed to classify beats as either normal or ventricular premature. Performance is evaluated on signals from nine hemodialysis treatments, using leave-one-out crossvalidation. The simultaneously recorded and annotated photoplethysmographic signal serves as the reference signal, with a total of 149,686 normal beats and 3574 VPBs. The results show that VPBs can be reliably detected, quantified by a Youden's J statistic of 0.9, for average cardiac pulse pressures exceeding 1 mmHg; for lower pressures, the J statistic drops to 0.55. It is concluded that the cardiac pressure signal is suitable for VPB detection, provided that the average cardiac pulse pressure exceeds 1 mmHg.
Acetylsalicylic acid decreases clotting in combination with enoxaparin during haemodialysis<i>in vitro</i> (2018)

Adding acetylsalicylic acid to HD circuits lowered the transmembrane pressure, better preserved platelet function and prolonged the time to circuit clotting, which in sum increases haemodialyser performance and may facilitate a more effective HD.
Purification of Stearidonic Acid from Modified Soybean Oil by Argentation Silica Gel Column Chromatography (2011)

Abstract The objective of this study was to purify stearidonic acid (SDA, 18:4 ω‐3) from modified soybean oil containing a mixture of over 20 fatty acids (23% SDA). Interest in obtaining purified fractions of SDA arises from reported health benefits associated with polyunsaturated fatty acids (PUFA), such as cardiovascular disease prevention. In addition, SDA may also provide improved stability characteristics since its unsaturation index is less than longer PUFA, such as eicosapentaenoic acid (EPA, 20:5 ω‐3). First, a chemical ethanolysis of modified soybean oil was performed to transform the triacylglycerols into fatty acid ethyl esters (FAEE). Then, the FAEE were fractionated and SDA‐EE was purified by argentation silica gel (10% AgNO 3 ) open column chromatography, which allows selectivity based on degree of unsaturation. Different FAEE sample loads and mobile phases were explored until the best purification of SDA‐EE was achieved. The solvents used were hexane and hexane:acetone mixtures (99 and 95%). Under the optimal conditions, a fraction with high SDA‐EE purity (96%) was obtained with 77% yield. Besides, it was possible to obtain another fraction enriched in α‐linolenic acid‐EE (37% purity and 68% yield) and γ‐linolenic acid‐EE (22% purity and 61% yield). A scaled‐up process resulted in 840 mg of final product composed of 97% SDA‐EE with 71% yield.
Influence of Thermocouple Thermal Inertia in Impingement Heat Transfer Experiments Using Transient Techniques (2012)

A typical transient heat transfer experiment for an impingement cooling configuration requires usually a temperature step in the flow. A moving isotherm of the liquid crystal surface coating is then monitored using a video camera. However, for small impingement configurations, when only a small number of holes is used, the massflow rates are relatively low, leading to very small plenum velocities. Therefore, a step change in the power settings does not cause a temperature step in the mainstream flow. Many researchers approximated the real hot gas temperature evolution by a number of ideal temperature steps (Duhamelâs superposition principle). However, thermocouple acquisition measurements are influenced by the size of the thermocouple due to thermal inertia and therefore direct evaluation of the heat transfer coefficient with these data may be in error. This paper suggests that the hot gas temperature which drives the transient experiment and is measured in the plenum can be corrected according to the time constant of the thermocouples. Several experiments were carried out in order to evaluate the time response of fine thermocouples with exposed junction. For the impingement configuration, a single row of five inline impingement holes is used at in a narrow passage configuration over a range of Reynolds numbers (15000-55000). The liquid crystal signal is evaluated with three different hot gas temperature approaches: (1) Perfect temperature step, (2) Duhamelâs principle in the acquired temperature data and (3) Correction of hot gas temperature for thermal inertia prior to Duhamelâs principle. The experimental data are analyzed by means of various post-processing procedures and aim to clarify and quantify the effect of thermocouple thermal inertia on the final results.
Dispersion in the 10-30 GHz Frequency Range: Atmospheric Effects and Their Impact on Digital Satellite Communications (1986)

Earth-space communications links operating above 10 GHz may be adversely affected by the earth's atmosphere and hydrometeors, particularly rain. These propagation phenomena are usually evaluated only for fading and depolarization effects. However, dispersion is an important factor in wide-band digitally modulated satellite links. In this paper we examine the mechanisms responsible for dispersion over bandwidths as great as 500 MHz in the 10-30 GHz range. The amplitude and phase effects of dispersion are quantified for a wide range of propagation conditions. The resulting propagation model is then used to generate estimates of performance degradation in wide-band QPSK systems through the use of computer simulation.
Inheritance and Allelism Analysis of Hypernodulating Genes in the NOD3‐7 and NOD2‐4 Soybean Mutants (2000)

Hypernodulating soybean [ Glycine max (L.) Merr.] mutants derived from cv. Williams showed greater early‐season dinitrogen fixation potential and partial tolerance to high levels of NO − 3 Understanding genetic control is essential to manipulation of this trait. Genetic analysis of the NOD1‐3 and NOD4 mutants, and the En6500 mutant, had previously shown that these three mutants were controlled by the same recessive allele at the rj 7 locus. However, genetic control of two additional hypernodulating mutants, NOD3‐7 and NOD2‐4, remained to be verified. We investigated the inheritance and allelic relationship of these latter mutations in relation to those previously studied. The cultivar Harosoy 63 was crossed to the NOD3‐7 and NOD2‐4 mutants to produce F 1 hybrids, F 2 progeny, and F 2 ‐derived families. Phenotypic segregation was examined. For allelism tests, hypernodulating progeny exhibiting purple hypocotyl, which were isolated from the F 2 segregants of the crosses with Harosoy 63, were used for crossing with the NOD2‐4 mutant. Resulting phenotypes were visually evaluated for hypernodulation at 14 d after planting (DAP) in the greenhouse. The results of genetic analysis indicated that a recessive allele was responsible for hypernodulation in the NOD3‐7 and NOD2‐4 mutants. Allelism analysis revealed that although the hypernodulating mutants were isolated from independent mutational events, the rj 7 locus controlled NOD‐type hypernodulating mutants and the En6500 mutant.
Staggercast: Demand-Side Management for ISPs (2016)

The continuing expansion of Internet media consumption has increased traffic volumes, and hence congestion, on access links. In response, both mobile and wireline ISPs must either increase capacity or perform traffic engineering over existing resources. Unfortunately, provisioning timescales are long, the process is costly, and single-homing means operators cannot balance across the last mile. Inspired by energy and transport networks, we propose demand-side management of users to reduce the impact caused by consumption patterns out-pacing that of edge network provision. By directly affecting user behaviour through a range of incentives, our techniques enable resource management over shorter timescales than is possible in conventional networks. Using survey data from 100 participants we explore the feasibility of introducing the principles of demand-side management in today's networks.
Neuron volume in the ventral horn in Wobbler mouse motoneuron disease: a light microscope stereological study (1997)

Previous pathological reports have indicated that swollen and vacuolated motoneuron cell bodies are the most predominant feature characterising Wobbler mouse motoneuron disease, but there has been little supportive evidence using area measurements. The present study focuses on the possible role of changes in neuronal nuclear and perikaryal volumes in the cervical spinal cord ventral horn, using new and traditional stereological probes which provide unbiased estimates of volume. Semithin sections from the ventral horn of Wobbler mice and age and sex-matched phenotypically normal littermates were examined at 2 ages (young and old). The young Wobbler group had significantly larger volume weighted mean perikaryal volumes compared with age-matched controls, reflecting the presence of large swollen cells characteristic of this group; this situation was reversed in the control group. Number-weighted perikaryal volume estimates in the old Wobbler group were smaller than in age-matched controls. The variation in perikaryal volume was greatest in the young Wobbler group in which the coefficient of variation was 127%. The mean number weighted and volume weighted mean nuclear volumes were significantly smaller in the old Wobbler group compared with age-matched controls and young Wobbler groups. The application of new stereological probes has enabled us to document more precisely these changes in neuronal structure in the Wobbler mutant mouse.
A wide tuning range VCO using capacitive source degeneration (2004)

This paper presents a wide tuning range LC voltage controlled oscillator with a new differential negative resistance cell that uses capacitive source degeneration. Traditional differential negative resistance cells use two transistors where the drains are cross-connected to the corresponding gates and the sources are ac grounded. This structure has a fairly large parasitic shunt capacitance. This effective parasitic capacitance combined with the fixed portion of the varactor and the inductor parasitic capacitance limits the tuning range and the maximum size of allowable inductor that is crucial for the large output swing. This paper shows that if the sources of the differential negative resistance cell are capacitively degenerated such that the effective parasitic capacitance is much smaller than that of traditional structures, then the tuning range can be increased or alternately the output swing can be increased for a given tuning range. An appropriate degenerating capacitance and device geometry can be selected to optimize the performance. The tradeoff between negative resistance and effective parasitic capacitance has also been considered. To verify this concept, a 5.3 GHz VCO with 21.5% tuning range and -106 dBc/Hz phase noise at 1 MHz offset from 5 GHz has been designed using the TSMC 0.25 /spl mu/m CMOS process.
Evaluation of sampling density on the accuracy of aortic pulse wave velocity from velocity‐encoded MRI in patients with Marfan syndrome (2012)

Improving spatial sampling density by adding two acquisition planes along the aorta results in more accurate PWV assessment, even when temporal resolution decreases. For regional PWV assessment in the aortic arch, EPI-accelerated and conventional PWV assessment are comparably accurate. Scan-time reduction makes EPI-accelerated PWV assessment the preferred method of choice.

Technique of the second satellite of CBERS-1 image multi-stage information extraction on land use and land cover (2004)

Since Oct. 21st 2003, on which the second satellite of CBERS-1 was successfully launched, professionals in the field of remote sensing pay more attention if information about the Earth's surface can be effectively extracted from its collection data. A method on extracting LULC information is discussed using data imaging on Feb. 2nd 2003 in This work. Remote sensing has inherent correlations with geo-knowledge. There are only few men interpreting remote sensing image with spectral knowledge. In this paper, a technique of multi-stage information extraction on LULC is present considering geo-knowledge by analyzing single band valve of sample end members, profile spectrum and constructing spectral band index. Different separable information of LULC is extracted at different stages, during which certain geo-knowledge is fused. In the end, this method is applied to an experiment area-Yun Nan DaLi, which obtains a better classified result compared with other supervised classified and unsupervised classified methods at the same area. Hence, it is useful to extract land use and land cover information from CBERS-1 image and extent application fields of CBERS-1.

Clinical Outcomes of Digital Cholangioscopy-Guided Procedures for the Diagnosis of Biliary Strictures and Treatment of Difficult Bile Duct Stones: A Single-Center Large Cohort Study (2021)

Although Spy DS (SpyGlass DS Direct Visualization System) is considered to be useful for the diagnosis of bile duct strictures and the treatment of bile duct stones, there is limited data to date validating its efficacy. We hence retrospectively evaluated the clinical outcomes of the use of Spy DS in a large number of patients. A total of 183 patients who underwent Spy DS-guided procedures for indeterminate bile duct strictures (<i>n</i> = 93) and bile duct stones (<i>n</i> = 90) were analyzed retrospectively. All patients (93/93) with bile duct strictures successfully underwent visual observation, and 95.7% (89/93) of these patients successfully underwent direct biopsy. The sensitivity, specificity, and overall accuracy were 94.7%, 83.3%, and 90.3%, respectively, for visual impression; 80.9%, 100%, and 89.2%, respectively, for histopathological analysis of a direct biopsy; and 96.5%, 91.7%, and 94.6%, respectively, for visual impression combined with biopsy. Successful visualization of the stones was achieved in 98.9% (89/90) of the patients, and complete stone removal was achieved in 92.2% (83/90) of the patients, with an average of 3.3 procedures. The adverse events rate was 17.5% (32/183; cholangitis in 15 patients, fever the following day in 25, pancreatitis in 1, hemorrhage in 1, and gastrointestinal perforation in 1). No administration of antibiotics before the procedure was found to be a statistically significant risk factor for the development of fever after the procedure (<i>p</i> < 0.01). Spy DS-guided procedures are effective for the diagnosis and treatment of bile duct lesions and can be performed with a low risk of serious adverse events.
Synthetic Biology in Immunotherapy and Stem Cell Therapy Engineering (2018)

In response to the changing landscape of medical challenges, pioneers in molecular biology and genetic engineering launched a new paradigm of pharmaceutical development. Unlike chemical pharmaceuticals and biologics, cellular therapeutics have the potential to establish prolonged proliferation in the patient and provide continual surveillance against disease relapse without repeated drug administration. This chapter discusses some of the challenges facing cell-based therapeutics - particularly cell-based immunotherapies - and highlights solutions that have been developed through the application of synthetic biology. Genetically engineered stem cells have been programmed to deliver cytotoxic molecules, angiostatic factors, and immunostimulatory cytokines to tumor cells, demonstrating the versatility and programmability of living cells as therapeutic agents. The ability to efficiently design, construct, and optimize synthetic biological systems that modify and/or interface with living cells is expanding new possibilities in the development of cellular therapeutics and offering enticing views of next generation strategies for disease treatment.
SIMS of Interfacial Segregation in Ceramics and Composites (1997)

Abstract Trace impurities and dopants in sintered ceramics, often at levels below 100 parts per million, can significantly affect the performance of the materials. In alumina (A12O3), it is believed that calcium and silicon, which are the main background impurities, cause abnormal grain growth. The addition of magnesium to alumina produces several beneficial results, including enhanced densification and improved corrosion resistance of the ceramic. For example, LUCALUX®, which is a dense, transparent ceramic, is made by adding a small amount of MgO (&amp;lt;0.25%) to the alumina. Primarily because they are difficult to detect and image, it has not been easy to determine experimentally the mechanisms by which trace constituents influence the sintering of ceramics. Imaging secondary ion mass spectrometry (SIMS) is a valuable analytical technique for the submicrometer characterization of ceramics. Relevant to this study, magnesium and isotopes of silicon, which have largely eluded detection by traditional techniques, can be measured with SIMS.
Inside Cover: Synthesis of [8]Cycloparaphenylene from a Square‐Shaped Tetranuclear Platinum Complex (Angew. Chem. Int. Ed. 4/2010) (2009)

From a square to a loop! In their Communication on page 757 ff., S. Yamago et al. describe the first synthesis of [8]cycloparaphenylene, which was achieved in three steps in 25 % overall yield from 4,4′-bis(trimethylstannyl)biphenyl and [PtCl2(cod)] (cod=1,5-cyclooctadiene) through a square-shaped platinum biphenyl intermediate. [8]cycloparaphenylene shows strong yellow-green fluorescence around 540 nm.
Dot Text Detection Based on FAST Points (2011)

In this paper, we propose a method for dot text detection based on FAST points. This problem is different from general scene text detection because of discontinuous text stroke. Unlike many other methods which assume that text is horizontally oriented, our method is able to deal with slant dot text. We extract interesting patches from FAST points and define four features based on the stroke and gray value similarity of dot text to describe a patch. Then, we generate some candidate regions from these patches and utilize SVM to filter out non-dot text ones with the first and second order moments of FAST points in them. Experimental results show that the proposed method is effective and fast to detect dot text.
LiFePO<sub>4</sub> Mesocrystals for Lithium‐Ion Batteries (2011)

Olivine LiFePO(4) is considered one of the most promising cathode materials for Li-ion batteries. A simple one-step, template-free, low-temperature solvothermal method is developed for the synthesis of urchinlike hierarchical mesocrystals of pristine LiFePO(4) as well as carbon-coated LiFePO(4) composites. Each urchinlike mesocrystal consists of LiFePO(4) sheets self-assembled via a dipolar field in spheres during a solvothermal process under the influence of Cl(-) anions. The obtained primary sheets of LiFePO(4) are single crystalline in nature and can be coated in situ with an amorphous nitrogen-doped carbonaceous layer several nanometers in thickness. To increase the conductivity of the carbon coating, the materials are subjected to further temperature treatment (700 °C) under an inert atmosphere. The lithium storage performance of the pure LiFePO(4) is compared with that of its carbon-coated counterparts.
