Emergence of traveling waves in linear arrays of electromechanical oscillators (2018)

Abstract Traveling waves of mechanical actuation provide a versatile strategy for locomotion and transport in both natural and engineered systems across many scales. These rhythmic motor patterns are often orchestrated by systems of coupled oscillators such as beating cilia or firing neurons. Here, we show that similar motions can be realized within linear arrays of conductive particles that oscillate between biased electrodes through cycles of contact charging and electrostatic actuation. The repulsive interactions among the particles along with spatial gradients in their natural frequencies lead to phase-locked states characterized by gradients in the oscillation phase. The frequency and wavelength of these traveling waves can be specified independently by varying the applied voltage and the electrode separation. We demonstrate how traveling wave synchronization can enable the directed transport of material cargo. Our results suggest that simple energy inputs can coordinate complex motions with opportunities for soft robotics and colloidal machines.

Incentive Based Demand Response Program for Power System Flexibility Enhancement (2020)

This article proposes a DR program characterized by a novel compensation scheme. The proposed scheme recognizes the different characteristics of curtailment, such as the total length of curtailments within a window of time, or the number of separate curtailment events (i.e., curtailment startup), and compensates the end-user accordingly. The proposed compensation scheme features a piece-wise reward function comprised of two intervals. DR participants receive a onetime reward upfront when they enroll in the DR program and accept a set of predefined curtailment aspects. Curtailment aspects in excess of the agreed quantities are rewarded at a linear rate. This design is tailored to appeal to residential DR participants, and aims to secure sufficient flexibility at minimum cost. The parameters of the smart contract are optimized such that the system's social welfare is maximized. The optimization problem is modeled as a mixed-integer linear program. Consequently, this article updates the unit-commitment (UC) formulation with the commitment aspects of DR units. The proposed extension to the UC problem considers the critical aspects of DR participation, such as: the total length of interruptions within a window, the frequency of interruptions within a time-window irrespective of their length, and the net energy deviation from the original load profile. Deployment of the smart DR contract in the unit dispatch problem requires translating DR participants' characteristics to their equivalent aspects in conventional thermal generators, such as minimum up time, minimum down-time, start-up and shutdown costs. The obtained results demonstrate significant improvement in social welfare, notable reduction of curtailed renewable energy and reduction in extreme ramping events of conventional generators.
Impaired lung perfusion in patients with congestive heart failure by quantitative MRI perfusion (2010)

Methods Study subjects were prospectively enrolled and underwent cardiac MRI at 1.5 T. First-pass perfusion was performed with 0.01 mmol/kg gadopentetate in 3 coronal slices covering anterior, mid and posterior lung fields during inspiration using a saturation recovery SSFP sequence. Mean signal intensity of all pixels in pulmonary parenchyma at each time point was evaluated using a custom modelindependent deconvolution program for perfusion quantitation. Pulmonary transit time was measured as the time interval between peak signal intensity in the main pulmonary artery and peak signal intensity in the left atrium. Cardiac function was assessed using SSFP standard short axis cine imaging. Pulmonary flow was measured by through plane phase contrast imaging in the main pulmonary artery. Results Of the 25 subjects enrolled 7 were normal controls and 15 were patients with systolic CHF in I-III NYHA functional class who completed lung perfusion imaging in inspiration. Average lung perfusion was reduced in CHF patients, 81 ± 32 ml/100 ml/min vs 118 ± 48 ml/100 ml/min in controls (p = 0.046). Similar to normal controls patients with CHF maintained a perfusion gradient in the gravity direction with the highest perfusion in posterior and the lowest in anterior lung field. However, the absolute perfusion was reduced in all lung fields with anterior, mid and posterior perfusion 58 ± 26, 85 ± 38, 106 ± 36 ml/100 ml/min in CHF patients and 73 ± 53, 116 ± 53, 165 ± 45 ml/100 ml/min in controls. Reduced lung perfusion was associated with lower pulmonary flow (indexed by BSA) (r = -0.771, p < 0.001), longer pulmonary transit time (r = -0.729, p < 0.001), a marker of total pulmonary resistance, lower LVEF (r = 0.443, p = 0.039) and lower RVEF (r = 0.474, p = 0.026). In a multivariate regression analysis including all variables associated with lung perfusion and an interaction term for pulmonary flow and pulmonary transit time since they were significantly correlated, the predictors of lung perfusion were pulmonary flow and flow/transit time interaction, suggesting the importance of both forward flow and total pulmonary resistance.
Characterization and Comparison of Arcelin Seed Protein Variants from Common Bean (1991)

Four variants of arcelin, an insecticidal seed storage protein of bean, Phaseolus vulgaris L., were investigated. Each variant (arcelin-1, -2, -3, and -4) was purified, and solubilities and M(r)s were determined. For arcelins-1, -2, and -4, the isoelectric points, hemagglutinating activities, immunological cross-reactivities, and N-terminal amino acid sequences were determined. On the basis of native and denatured M(r)s, the variants were classified as being composed of dimer protein (arcelin-2), tetramer protein (arcelins-3 and -4), or both dimer and tetramer proteins (arcelin-1). Although the dimer proteins (arcelins-1d and -2) could be distinguished by M(r)s and isoelectric points, they were identical for their first 37 N-terminal amino acids and had similar immunological cross-reactions, and bean lines containing these variants had a DNA restriction fragment in common. The tetramer proteins arcelin-1t and arcelin-4 also could be distinguished from each other based on M(r)s and isoelectric points; however, they had similar immunological cross-reactions and they were 77 to 93% identical for N-terminal amino acid composition. The similarities among arcelin variants, phytohemagglutinin, and a bean alpha-amylase inhibitor suggest that they are all encoded by related members of a lectin gene family.
Cuticular Ridges in a Mite (1973)

Many species of arachnids possess cuticular ridges, the function of which is not known. In the present investigation the structural properties of the ridges in a Trombidiform mite, Panonychus citri were studied, with a view towards discovering the function of the ridges. For scanning electron microscopy the animals were mounted on metal pos s previously coated with conducting silver paint. Best results were obtained by examining live animals, mounted on the posts immediately before examination. For transmission electron microscopy the animals were fixed in cacodylate-buffered glutaraldehyde, post-fixed in osmium, embedded in Spurr's low viscosity epoxy resin, and sectioned on diamond knives.
Phytochrome Modification and Light-enhanced, In Vivo-induced Phytochrome Pelletability (1980)

Phytochrome that was induced by red irradiation in vivo to pellet with subcellular material and that was released from the pellet by removal of divalent cations exhibited altered characteristics. Compared to phytochrome extracted in a soluble red-absorbing form from etiolated tissue, pelleted and released phytochrome, which was also assayed in the red-absorbing form even though pelleted in the far-red-absorbing form, showed 50% greater micro complement fixation activity, eluted closer to the void volume of a Sephadex G-200 column, and electrophoresed more slowly on sodium dodecyl sulfate-polyacrylamide gels. Data presented here document that phytochrome pelleted in the far-red-absorbing form differs from soluble phytochrome extracted from nonirradiated tissue. These data, however, do not permit the conclusion that there is a causal relationship between pelletability and phytochrome modification.
Characterization of structure-activity relationships for serotonin receptors coupled to adenylate cyclase. (1990)

The need to develop selective compounds for 5-HT receptors requires further elucidation of structure-activity relationships involved with receptor recognition and activation. In particular, there is great interest in the involvement of the 5-HT₁(A) receptor in therapeutic treatment of conditions such as anxiety, depression and hypertension. Despite previous attempts to define the pharmacophore for 5-HT₁(A) receptors, the structural requirements for 5-HT₁(A) receptor activity remain largely unexplored. In fact, no selective 5-HT₁(A) antagonists currently exist. Binding assays provide important information concerning receptor affinity, but do not reflect functional consequences of receptor interaction. One of the functional correlates of the 5-HT₁(A) receptor is the inhibition of forskolin-stimulated adenylate cyclase (FSC). The objective of this dissertation was to assess the merits of using the FSC assay as a functional screen to determine 5-HT₁(A) intrinsic activity of novel compounds. From the variety of compounds tested, it was apparent that the FSC assay can be used as an in vitro functional screen for assessing 5-HT₁(A) agonistic and antagonistic, as well as partial agonistic, activity. All putative 5-HT₁(A) agonists tested in the FSC assay had potencies (EC₅₀) that were less than their respective 5-HT₁(A) binding affinities (Kᵢ). The use of pindolol to block 5-HT₁(A) receptors, and therefore cause a rightward shift in any observed inhibition curve, provided qualitative evidence of 5-HT₁(A) interaction. Quantitative evaluation of 5-HT₁(A) activity had to be approached cautiously, due to possible complications arising from non-5-HT₁(A)-mediated inhibition. The data for a series of enanatiomers of 8-OH-DPAT and its analogs supported a recently proposed model for the 5-HT₁(A) agonist pharmacophore. Also, within the enantiomeric pairs exhibiting stereoselectivity, the compound with the higher 5-HT₁(A) affinity also possessed greater 5-HT₁(A) agonistic activity. Within a series of tetrahydropyridylindoles (THPI), the 4-THPI analogs generally had both greatest 5-HT₁(A) affinity and agonistic activity, although there were exceptions to this trend. Several compounds, whose structures were based on the small molecules of the 5-HT₁(A) agonist 8-hydroxy-2-(di-n-propylaminotetralin) (8-OH-DPAT) and 5-HT itself, demonstrated potential antagonistic activity in the FSC assay. Further analysis of an extended series of these compounds in the FSC assay is required to establish specific conclusions concerning the 5-HT₁(A) pharmacophore.
<title>Simulation of EBG structures in coplanar waveguides with the aid of FDTD</title> (2004)

In the paper, electromagnetic bandgap (EBG) structures in coplanar waveguide (CPW) technology are presented. In order to design this type of circuits, a custom Finite Difference Time Domain (FDTD) code is employed. Due to the fact that simulation is performed in the time domain, a wide frequency response can be obtained in a reasonable amount of time, being a numerically efficient technique. Simulation of several proposed designs are presented and these results are validated with measurements from fabricated prototypes. The results show that the use of FDTD techniques is adequate for the design of EBG devices in planar circuit technology in general.

Class D audio amplifier with 4th order output filter and self-oscillating full-state hysteresis based feedback driving capacitive transducers (2014)

A practical solution is presented for the design of a non-isolated high voltage DC/AC power converter. The converter is intended to be used as a class D audio amplifier for a Dielectric Electro Active Polymer (DEAP) transducer. A simple and effective hysteretic control scheme for the converter (buck with fourth-order output filter) is developed and analyzed. The proposed design is verified experimentally by a 125 VAR prototype amplifier, capable of delivering a peak output voltage of 240 V within the frequency range of 100 Hz - 3.5 kHz. A peak efficiency of 87 % is reported.
Lifetime-throughput tradeoff for elastic traffic in multi-hop hotspot networks (2005)

Multi-hop hotspot networks consist typically of one or few wireless access nodes (ANs) and many self-organizing, self-coordinating, and battery-powered portable nodes (PNs). Nodes maintain cooperative connectivity among each other without any need for a wired infrastructure. On the one hand, because PNs are power-limited, efficient use of their available energy resources is crucial to their lifetimes. On the other hand, because higher rates of elastic flows provide higher QoS, it is desirable to maximize the throughput. Unfortunately, increasing lifetime and maximizing throughput are two conflicting objectives which cannot he optimized simultaneously. In this paper, we propose an extension of our earlier-presented scheme (B. Hamdaoui et al., IEEE Press Monograph on Sensor Network Op., 2004) to support elastic traffic routing in multi-hop hotspot networks. The proposed routing scheme strikes a balance between the need to keep the nodes operational with sufficient energy resources and the desire to allocate higher throughput to elastic flows. The proposed scheme also deals systematically with both objectives of maximizing the network lifetime and minimizing the total consumed energy.
Detection of Antibodies to Spotted Fever Group Rickettsiae and Arboviral Coinfections in Febrile Individuals in 2014–2015 in Southern Coastal Ecuador (2019)

Tick-borne diseases (TBDs) are a growing public health threat and are increasingly identified as the cause of undifferentiated febrile illness. There is a significant gap in our understanding of ticks and their associated pathogens in Ecuador. An arboviral surveillance study allowed us to explore potential exposure to TBDs in febrile subjects. We tested plasma samples from 222 febrile subjects for spotted fever group rickettsial (SFGR) antibodies from southern coastal Ecuador in 2014-2015 via ELISA. Fifty-five (25%) subjects had evidence of anti-SFRG IgG or IgM antibodies. Although attempts to detect <i>Rickettsia</i> species in plasma by polymerase chain reaction were unsuccessful, these preliminary data suggest the possibility of endemic SFGR transmission in Ecuador. To better understand the burden and entomological risk for TBDs in Ecuador, future studies should expand TBD surveillance in humans, document common human-biting ticks, and measure pathogen carriage rates in questing ticks.

Treatment of urinary schistosomiasis: methodological issues and research needs identified through a Cochrane systematic review (2009)

Guidelines recommend praziquantel (PZQ) for the treatment and control of schistosomiasis, with no real alternative. Metrifonate was still widely used against Schistosoma haematobium in the 1990s, and then withdrawn. Experimental studies and clinical trials suggest that artemisinin compounds are active against S. haematobium. In a Cochrane systematic review assessing the efficacy and safety of drugs for treating urinary schistosomiasis, 24 randomized controlled trials (n=6315 individuals) met our inclusion criteria. These trials compared a variety of single agent and combination regimens with PZQ, metrifonate or artemisinin derivatives. The review confirmed that both the standard recommended doses of PZQ (single 40 mg/kg oral dose) and metrifonate (3x7.5-10 mg/kg oral doses administered fortnightly) are efficacious and safe in treating urinary schistosomiasis, but there is no study comparing these two regimens head-to-head. There is currently not enough evidence to evaluate artemisinin compounds. Most of the studies included in the Cochrane systematic review were insufficiently powered, lacked standardization in assessing and reporting outcomes, and had a number of methodological limitations. In this paper we discuss the implications of these findings with respect to public health and research methodology and propose priority research needs.

A COMPARISON OF THE SINGLE-PHASE INDUCTION MOTOR WITH AN ASYMMETRICAL STATOR YOKE TO THE SHADED-POLE MOTOR (1984)

Abstract The single-phase induction motor with yoke asymmetries can be calculated by means of the same computer program as the shaded-pole motor and compared with it, if some reluctances are substituted by additional windings. The influence of many different parameters on the performance is demonstrated
In Vitro Investigation of the Effect of Oral Bacteria in the Surface Oxidation of Dental Implants (2015)

Implant surface oxidation occurred in bacteria-containing medium even at early stages of immersion (2 days). The incremental corrosion resulted in dissolution of metal ions and debris into the testing solution. Dissolution of metal ions and particles in the oral environment can trigger or contribute to the development of peri-implantitis at later stages.
End to end learning and optimization on graphs (2019)

Real-world applications often combine learning and optimization problems on graphs. For instance, our objective may be to cluster the graph in order to detect meaningful communities (or solve other common graph optimization problems such as facility location, maxcut, and so on). However, graphs or related attributes are often only partially observed, introducing learning problems such as link prediction which must be solved prior to optimization. Standard approaches treat learning and optimization entirely separately, while recent machine learning work aims to predict the optimal solution directly from the inputs. Here, we propose an alternative decision-focused learning approach that integrates a differentiable proxy for common graph optimization problems as a layer in learned systems. The main idea is to learn a representation that maps the original optimization problem onto a simpler proxy problem that can be efficiently differentiated through. Experimental results show that our ClusterNet system outperforms both pure end-to-end approaches (that directly predict the optimal solution) and standard approaches that entirely separate learning and optimization. Code for our system is available at https://github.com/bwilder0/clusternet.
Regeneration of blood-forming organs after autologous leukocyte transfusion in lethally irradiated dogs. II. Distribution and cellularity of the marrow in irradiated and transfused animals (1976)

Dogs were given transfusions of cryopreserved autologous mononuclear blood leukocytes after 1200 roentgens (R) (midline dose) whole-body x- irradiation. Bone marrow repopulation was studied by means of histomorphological methods at days 9 and 10 after transfusion of an average of 3 X 10(9), 7 X 10(9), 13 X 10(9), and 31 X 10(9) cells. The return of marrow cellularity to normal values was related to the number of cells transfused. With low cell doses (3 X 10(9) and 7 X 10(9)), the marrow regeneration at 10 days was focal. There were groups of cells (colonies) showing either erythropoiesis, myelopoiesis, or megakaryocytopoiesis in the osteal niches of the trabecular bones. Frequently such niches were seen showing complete cellular recovery next to niches with complete aplasia. With higher cell doses, all niches showed hemopoietic regeneration, and the cellularity approached normal values. No hemopoietic regeneration was observed in those skeletal parts that do not show hemopoiesis, even under normal circumstances.
Evaluation of artificial neural networks for the prediction of pathologic stage in prostate carcinoma (2001)

BACKGROUND Currently, the standard for predicting pathologic stage from information available at the time of prostate biopsy is the “Partin nomograms” that were derived using logistic regression analysis. The authors retrospectively reviewed a large series of men with clinically localized prostate carcinoma who underwent staging pelvic lymphadenectomy and radical retropubic prostatectomy. They then utilized pathologic and clinical data at the time of prostate biopsy to develop and test an artificial neural network (ANN) to predict the final pathologic stage for this group of men. They then compared the results of ANN with the previous nomograms. METHODS Five thousand seven hundred forty-four men were treated at the authors' institution from 1985 to 1998. An ANN was developed using two randomly selected training and validation sets for predicting pathologic stage. Input variables included age, preoperative serum prostate specific antigen level, clinical TNM (tumor, lymph node, and metastasis) classification, and Gleason score from the biopsy specimen. Outcomes included organ confinement and lymph node involvement status. RESULTS The ANN was slightly superior to the nomograms in predicting pathologic stage, such as organ confinement and lymph node involvement status. CONCLUSIONS In predicting organ confinement and lymph node involvement status, ANN was more accurate and had a larger area under ROC than the nomograms based on the logistic regression method. Artificial neural network models can be developed and used to better predict final pathologic stage when preoperative pathologic and clinical features are known.
