Applications of electro-rheological fluids in vibration control: a survey (1996)

Electro-rheological (ER) fluids are now regarded as one of the most versatile of the materials available for building smart structures and machines. In principle, ER fluids promise an elegant means of providing continuously variable forces for the control of mechanical vibrations. In practice, the development of industrial devices has been hampered by the unavailability of suitable ER fluids. Prompted by recent advances in ER fluid development this paper provides a comprehensive survey of ER devices for vibration control. The key modes of operation are identified and progress towards a unified approach to visualizing the macroscopic behaviour is summarized before presenting a comprehensive survey which includes contributions to the identification of ER fluid dynamics and the application of feedback control. The discussion of results includes some thoughts on future trends.

Identification and control of peristaltic pumps in hemodialysis machines (2013)

In hemodialysis machines peristaltic pumps are responsible for the transfer of fluids. The main characteristic of these pumps is that they can transport the solutions with significant error. That depends on the tube segment deviation caused through the production. Due to the fact that the medical fluid represents sometimes drugs and in the same time it is required to control the fluid balance of the patient, it is important to transfer these fluids as accurate as possible. The goal of the paper is to design a controller that satisfies the mentioned requirements. First, the system identification is realized by classical moving average method (ARX), followed by the design of two controllers: a classical PID one and a fuzzy controller. After comparing their simulation results, the most preferable one was implemented in practice. Real simulation results of the implemented controller end the paper.

Partial-FOV reconstruction in dynamic spiral imaging (2000)

In many applications of dynamic MR imaging, only a portion of the field-of-view (FOV) exhibits considerable variations in time. In such cases, a prior knowledge of the static part of the image allows a partial-FOV reconstruction of the dynamic section using only a fraction of the raw data. This method of reconstruction generally results in higher temporal resolution, because the scan time for partial-FOV data is shorter. The fidelity of this reconstruction technique depends, among other factors, on the accuracy of the prior information of the static section. This information is usually derived from the reconstructed images at previous time frames. This data, however, is normally corrupted by the motion artifact Because the temporal frequency contents of the motion artifact is very similar to that of the dynamic section, a temporal low-pass filter can efficiently remove this artifact from the static data. The bandwidth of the filter can be obtained from the rate of variations inside and outside the dynamic area. In general, when the temporal bandwidth is not spatially uniform, a bank of low-pass filters can provide a proper suppression of the motion artifact outside the dynamic section. This reconstruction technique is adapted for spiral acquisition and is successfully applied to cardiac fluoroscopy, doubling the temporal resolution.
E112D polymorphism in the prolylcarboxypeptidase gene is associated with blood pressure response to benazepril in Chinese hypertensive patients. (2009)

Our data suggest that the E112D polymorphism in the PRCP gene may be a useful genetic marker to predict the antihypertensive effect of short-term benazepril treatment in hypertensive patients of Anhui Province, China.
Three-layered proteomic characterization of a novel<i>ACTN4</i>mutation unravels its pathogenic potential in FSGS (2016)

Genetic diseases constitute the most important cause for end-stage renal disease in children and adolescents. Mutations in the ACTN4 gene, encoding the actin-binding protein α-actinin-4, are a rare cause of autosomal dominant familial focal segmental glomerulosclerosis (FSGS). Here, we report the identification of a novel, disease-causing ACTN4 mutation (p.G195D, de novo) in a sporadic case of childhood FSGS using next generation sequencing. Proteome analysis by quantitative mass spectrometry (MS) of patient-derived urinary epithelial cells indicated that ACTN4 levels were significantly decreased when compared with healthy controls. By resolving the peptide bearing the mutated residue, we could proof that the mutant protein is less abundant when compared with the wild-type protein. Further analyses revealed that the decreased stability of p.G195D is associated with increased ubiquitylation in the vicinity of the mutation site. We next defined the ACTN4 interactome, which was predominantly composed of cytoskeletal modulators and LIM domain-containing proteins. Interestingly, this entire group of proteins, including several highly specific ACTN4 interactors, was globally decreased in the patient-derived cells. Taken together, these data suggest a mechanistic link between ACTN4 instability and proteome perturbations of the ACTN4 interactome. Our findings advance the understanding of dominant effects exerted by ACTN4 mutations in FSGS. This study illustrates the potential of genomics and complementary, high-resolution proteomics analyses to study the pathogenicity of rare gene variants.
Spatial scan statistics (2006)

Spatial scan statistics are used to determine hotspots in spatial data, and are widely used in epidemiology and biosurveillance. In recent years, there has been much effort invested in designing efficient algorithms for finding such "high discrepancy" regions, with methods ranging from fast heuristics for special cases, to general grid-based methods, and to efficient approximation algorithms with provable guarantees on performance and quality.In this paper, we make a number of contributions to the computational study of spatial scan statistics. First, we describe a simple exact algorithm for finding the largest discrepancy region in a domain. Second, we propose a new approximation algorithm for a large class of discrepancy functions (including the Kulldorff scan statistic) that improves the approximation versus run time trade-off of prior methods. Third, we extend our simple exact and our approximation algorithms to data sets which lie naturally on a grid or are accumulated onto a grid. Fourth, we conduct a detailed experimental comparison of these methods with a number of known methods, demonstrating that our approximation algorithm has far superior performance in practice to prior methods, and exhibits a good performance-accuracy trade-off.All extant methods (including those in this paper) are suitable for data sets that are modestly sized; if data sets are of the order of millions of data points, none of these methods scale well. For such massive data settings, it is natural to examine whether small-space streaming algorithms might yield accurate answers. Here, we provide some negative results, showing that any streaming algorithms that even provide approximately optimal answers to the discrepancy maximization problem must use space linear in the input.
Electroluminescent Lines in ZnS Powder Particles (1963)

Existing theories of ‐powder‐EL are shown to be unable to explain the new findings of electroluminescent striations or lines described in Part I of this work. Several new hypotheses are discussed. Among these, a model seems to be likely which is based on simultaneous bipolar field‐emission from opposite ends of conducting imperfection lines into the insulating crystallite, with trapping of injected holes in activator centers, and recombination with mobile electrons at field‐reversal. This model, which is shown to be consistent with facts, is discussed in detail. A new impact ionization model is also described which is very similar to that of the field‐mission model. At present, it is experimentally indistinguishable from the field‐emission model.
Helicase‐Primase as a Target of New Therapies for Herpes Simplex Virus Infections (2014)

The seminal discovery of acyclovir 40 years ago heralded the modern era of truly selective antiviral therapies and this drug remains the therapy of choice for herpes simplex virus infections. Yet by modern standards, its antiviral activity is modest and new drugs against novel molecular targets such as the helicase-primase have the potential to improve clinical outcome, particularly in high-risk patients. A brief synopsis of current therapies for these infections and clinical need is provided to help provide an initial perspective. The function of the helicase-primase complex is then summarized and the development of new inhibitors of the helicase-primase complex, such as pritelivir and amenamevir, is discussed. We review their mechanism of action, propensity for drug resistance, and pharmacokinetic characteristics and discuss their potential to advance current therapeutic options. Strategies that include combinations of these inhibitors with acyclovir are also considered, as they will likely maximize clinical efficacy.
Collisional redistribution effects on x-ray laser saturation behavior (1994)

We recently published a detailed summary of our experimental and theoretical research on Ne-like Se x-ray laser line widths, and one of our conclusions was that collisional redistribution rates are likely to have an effect on the saturation behavior of the 206.4 {angstrom} Se x-ray laser. In this paper we focus on the effects of collisional redistribution on x-ray laser gain coefficients, and discuss ways of including these effects in existing laser line- transfer models.
Arterial Wall Hypertrophy and Stiffness in Essential Hypertensive Patients (1995)

The purpose of this article is to review some clinical and fundamental evidence that hypertension-induced arterial wall hypertrophy at the site of large and medium-sized arteries is not necessarily associated with a decreased arterial distensibility and increased elastic modulus, and to demonstrate the opposing effects of aging and hypertension-induced hypertrophy on the arterial mechanics in vivo. in the studies reported here, the elastic properties of large and medium-sized arteries were noninvasively assessed from the simultaneous measurement of internal diameter and blood pressure inside the systolic-diastolic range. The distensibility of a medium-sized artery, the radial artery, in untreated essential hypertensive patients was not significantly different from that of normotensive control subjects when the two groups were compared at their respective mean arterial pressures. Despite increased wall thickness, the stiffness of the radial artery wall material, assessed by the incremental modulus of elasticity (Young's modulus), was not increased in hypertensive patients. At the site of a larger, more elastic artery, such as the common carotid artery, distensibility of hypertensive patients was significantly lower than that of normotensive subjects when the two groups were compared at their respective mean arterial pressures, but distensibility at 100 mm Hg was not significantly different between the two groups. Aging may alter distensibility independently of blood pressure, because carotid distensibility at 100 mm Hg was negatively correlated with age. In spontaneously hypertensive rats the elastic modulus of the common carotid artery wall material was not significantly different from that of Wistar-Kyoto rats at a given circumferential stress.(ABSTRACT TRUNCATED AT 250 WORDS)
Further investigation on methoctramine-related tetraamines: effects of terminal N-substitution and of chain length separating the four nitrogens on M2 muscarinic receptor blocking activity. (1991)

A series of tetraamines related to methoctramine (1) was synthesized and evaluated for its blocking activity on M2 and M3 muscarinic receptors of guinea pig left atria and ileum, respectively. Thus, tetraamines 2-7 were synthesized to evaluate the effect on affinity of replacing the 2-methoxybenzyl moiety of methoctramine by a phenethyl-type substituent. Furthermore, tetraamines 8 and 9 were investigated to analyze the effect on affinity of the chain length separating the inner nitrogens and the inner from outer nitrogens while keeping the total distance between the two outer nitrogens equal to that of methoctramine. It turned out that all the tetraamines investigated, although showing a significant affinity, were less active than methoctramine at M2 muscarinic receptors. The underlying drug-receptor interaction mechanisms are discussed.
Facile Carbolithiation of Bent Alkyne without Catalyst. Tandem Route to Dibenzo[<i>b</i>,<i>f</i>]pentalenes from Dibenzocyclooctadiyne (2008)

Abstract Nucleophilic addition of RLi to a triple bond of dibenzocycloocta[a,e]diyne provides dibenzo[b,f]pentalene motif through trans-annulation of the resulting vinyllithium. Dibenzopentalene anion thus formed reacts with various electrophiles such as aldehydes, alkyl halides, acid halide, and Me3SiCl to give the corresponding products.

Flow cytometric evaluation of platelet activation in blood collected into EDTA vs. Diatube‐H, a sodium citrate solution supplemented with theophylline, adenosine, and dipyridamole (1995)

With platelet activation, there is modulation of platelet surface molecule expression. In flow cytometric analyses of in vivo platelet activation, results are often confounded by activation induced in vitro by the preparative procedures. It is particularly important therefore to prevent or retard platelet activation as soon as possible after withdrawal of the blood sample. Taking blood into paraformaldehyde, or fixing the cells with paraformaldehyde as soon as possible after withdrawal, has been employed to prevent platelet activation in vitro, but paraformaldehyde-fixed platelets cannot be further used in functional studies. We investigated the efficacy of Diatube-H, a commercially available combination of platelet antagonists (theophylline, adenosine, and dipyridamole), in preventing or retarding platelet activation in vitro, along with its effects on modulation of platelet membrane glycoproteins (GP) and adhesion molecules. In contrast to blood taken into EDTA, blood taken into Diatube-H vacutainer tubes could be stored at room temperature for up to 4 hr prior to paraformaldehyde fixation without significant in vitro platelet activation, as measured by CD62P, CD63 and modulation of GPIb and GPIIbIIIa surface expression. Hence, paraformaldehyde fixation could be deferred for several hours, permitting transport of samples from distant sites. Studies of thrombin-induced platelet activation indicated that platelets taken into Diatube-H remained functional i.e. were able to be activated. Expression of the CD29, CD49b and CD31 adhesion molecules on the platelet surface was unaffected by storage in Diatube-H. The results suggest that Diatube-H may be a useful reagent for flow cytometric studies of platelets when the samples cannot be processed immediately.
One view of WCT seminar (1998)

For a variety of reasons, NADCA has not or cannot fulfill all of the needs of the expanding nuisance wildlife control industry. This is not too surprising, since one organization cannot be all things to all people. The Wildlife Society seemed unable to adapt to the emerging concerns in conservation biology, and this led to the development of the Society for Conservation Biology.
Sugar-induced conformational changes in boronic acid-appended poly(L- and D-lysine)s and sugar-controlled orientation of a cyanine dye on the polymers (1995)

Poly(L- and D-lysine)s have been modified with para- or meta-phenylboronic acid derivatives which act as sugar-binding sites (L-1 and D-1 for the para-isomer and L-2 for the meta-isomer). When monosaccharides were added to the L-1 solution, the helix content (monitored by CD spectroscopy) increased and the pH which gives the maximum helix content shifted to a lower pH region. The magnitude of the pH shift was correlated with the affinity of monosaccharides for phenylboronic acid. The pH dependence of the helix content in the presence of D- or L-fructose was similar although a slight difference was seen at the low pH region. This is a novel attempt towards the control of a polypeptide's conformation by sugars. A cyanine dye (4) can be orientated on 1 or 2 in the presence of saccharides. Judging from the CD spectra, the orientation in the presence of 1 is more ordered than that in the presence of 2. The main driving-force for the association of 4 with 1 or 2 is the electrostatic attraction between cationic 4 and the anionic centre developed on the polymer by complexation of the boronic acid residue with saccharides. The chiral orientation of 4 can be monitored by a CD spectroscopic method: it is mainly governed by the chirality of 1 but not by the chirality of saccharides. This is a novel system to control the dye orientation by the cooperative action of naturallyoriginated α-amino acids and saccharides.
Effects of Velocity Modulation during Surgical Needle Insertion (2005)

Precise interstitial intervention is essential for many medical diagnostic and therapeutic procedures. But accurate insertion and placement of surgical needle in soft tissue is quite challenging. The understanding of the interaction between surgical needle and soft tissue is very important to develop new devices and systems to achieve better accuracy and to deliver quality treatment. In this paper we present the effects of velocity (linear, rotational, and oscillatory) modulation on needle force and target deflection. We have experimentally verified our hypothesis that needle insertion with continuous rotation reduces target movement and needle force significantly. We have observed little changes in force and target deflection in rotational oscillation (at least at lower frequency) of the needle.
Immersive Panoramic Imagery (2005)

An immersive experience where one views imagery captured from a panoramic camera with a head mounted display (HMD) or "cave" display system is an example of image processing that would be appreciated by the masses. In such a system, a user can see what would be seen from several viewpoints in a natural way by simply moving their head around. Virtual perspective views would be generated from recorded imagery collected by a panoramic camera from a set of locations. With image based rendering techniques, the user could also see views from viewpoints different from where the panoramic camera was placed. This paper proposes a simple framework for designing such systems based on image cubes which has the benefits of fast low latency operation and an efficient way to create intermediate images. The image cube method de-couples the image creation from the output image generation for the low latency required for realistic HMD immersive viewing. A fast algorithm for generating intermediate views along linear paths between capture sites based on pre-calculated disparity maps is also presented. A prototype system is shown.

Communication Options for Network RTK / SAPOS ® Realization 1 (2005)

Abstract- Real-Time Kinematic (RTK) service providers compute RTK corrections based on the observations of networks of GNSS (Global Navigation Satellite Systems like GPS or GLON-ASS) reference stations with station distances of about 50 to 80 kilometres. This correction data enables Network RTK users to position themselves with centimetre accuracy in real-time using a single GNSS-receiver. The selection of appropriate communication channels for the distribution of Network RTK corrections is the key to a successful positioning service. The German Satellite Positioning Service SAPOS was one of the first RTK-services using the Network RTK ap-proach. More than 250 reference stations are deployed nationwide. Presently, SAPOS Network RTK corrections are mainly received by mobile phone (GSM). 1 Network RTK Real-Time Kinematic (RTK) positioning with centimetre accuracy requires the re-ception of GNSS code and carrier phase correction data. Observations or observa-tion corrections of a single reference station are transmitted for single-base RTK. In the case of Network RTK the observations of several reference stations are usually pre-processed in a central computing facility and network corrections are then made available to the user. The crucial part of the pre-processing consists of the resolution of the carrier phase ambiguities in the network data [1].
A programmable framework for the deployment of services and protocols in mobile ad hoc networks (2007)

Mobile ad hoc networks (MANETs) are characterized by their heterogeneity and the diverse capabilities of their nodes given that almost any device with a wireless network interface can join such a network. In such an environment it is difficult to dynamically deploy services and protocols without a common understanding among the participating nodes and their capabilities. A deployment/provisioning framework must cope with the high-level of device heterogeneity, degree of mobility, and should also take into account the potentially limited device resources. This paper presents a context-based programmable framework for dynamic service/protocol deployment that allows the nodes of a mobile ad hoc network to download and safely activate required service/protocol software dynamically. Downloading and activation can be triggered through preconditions evaluated according to available contextual information. This strategy leads to the alignment of the nodes' capabilities so that common services and protocols can be deployed even if they are not available at every node. In addition, dynamic context-driven deployment may lead to a degree of network self-optimization. We present the programmable framework and functionality and evaluate its various aspects through testbed experimentation, simulation and analytical modeling. The results demonstrate good performance with respect to the supported functionality.
Electromechanical Energy Conversion in Double Cylindrical Structures (1963)

Terminal characteristics of machines without saliency on either member are derived from the solution of Maxwell's equations in the air gap, using conductor configurations which may be present in actual machines. First, the harmonic current sheets are generated. Then energy methods are employed to formulate the equations of motion for both the electric and mechanical terminals. The formulation is general, with respect to both the machine construction and the number of harmonics included.
