Software-defined Wireless Charging of Internet of Things using Distributed Beamforming (2016)

Smart homes will compose of multiple sensors that will sense, compute and transmit information to a central cloud, all of which are energy consuming tasks. We propose to demonstrate a software-defined solution for wirelessly charging these sensors using RF energy, thereby extending their lifetimes. In our demo, the actions of more than one energy transmitter (ET) are synchronized in phase and frequency in real time using periodic feedback from the target sensor, but without any common clock reference. The controller selects the optimal subset of ETs to satisfy the energy request from a given sensor, which cooperatively beamform RF energy towards that sensor. Our software-defined framework, implemented in Python, allows the central controller to automatically discover the installed sensors, obtain energy needs, and schedule charging tasks in an asynchronous and non-blocking manner that allows the network to scale. The demonstration includes advancements in design and fabrication of RF energy harvesting circuits that interface with the TI EZ430 sensors, implementation of a software-defined control and data plane, as well as a real-time distributed beamforming algorithm on USRP radios that results in a battery-free network of sensors.
Refinement of a hematogenous localized osteomyelitis model in pigs (2016)

We have previously developed a model of localized osteomyelitis by injecting Staphylococcus aureus (S. aureus) unilaterally into the femoral artery of juvenile domestic pigs (Johansen et al., 2012; Nielsen et al., 2015). We used this model for the evaluation of bone-infection tracers applicable for positron emission tomography (PET) and single-photon emission computed tomography (SPECT) (Nielsen et al., 2015). However, several of the 40 kg pigs were euthanized prior to PET and SPECT scanning due to lameness, shallow respiration, fever and anorexia; the last three clinical signs indicating dissemination of S. aureus to the lungs and other internal organs. We therefore decided to refine our model in order to improve the success rate. We speculated that younger pigs might respond differently to inoculations. A total of ten female domestic pigs were included in our study, three with a body weight of 40 kg (
Graphene from Amorphous Titanium Carbide by Chlorination under 200°C and Atmospheric Pressures (2014)

The synthesis of graphene via decomposition of SiC has opened a promising route for large-scale production of graphene. However, extremely high requirements for almost perfectly ordered crystal SiC and harsh process conditions such as high temperatures (>1200 °C) and ultra-high vacuum are two significant challenges hindering its wide use to synthesize graphene by decomposition of SiC. Here, we show that the readily available precursor of carbides, amorphous TiC (a-Ti(1-x)C(x)), can be transformed into graphene nanosheets (GNS) with tunable layers by chlorination method at very low temperatures (200 °C) and ambient pressures. Moreover, freestanding GNS can be achieved by stripping off GNS from the surface of resulting particles. Therefore, our strategy, the direct transformation of a-Ti(1-x)C(x) into graphene, is simple and expected to be easily scaled up.
A Method for Automatic Detection of Psychomotor Entrainment (2015)

Group interaction is an important aspect of human social behavior. During some group events, the activities performed by each group member continually influence the activities of others. This process of influence can lead to synchronized group activity, or the entrainment of the group. Understanding entrainment is important, because it can be a critical behavioral indicator of group cohesiveness, and can provide context for accurately understanding a group's affective behavior. In this paper, we present a novel method to automatically detect group psychomotor entrainment, which takes multiple types of discrete, task-level events into consideration. We experimentally validated the method on two synchronous rhythmic activities, “the cup game” and a marching task. We also compared its accuracy against two alternate synchrony detection methods in the literature. The results suggest our method can successfully measure group psychomotor entrainment, and is more accurate compared to other methods. This method will be useful to researchers interested in quantitatively and automatically measuring entrainment, and can also provide insight into understanding how groups interact socially.
Crosslinking of 1,9‐bis[glycidyloxypropyl]penta‐ (1′H,1′H,2′H,2′H‐perfluoroalkylmethylsiloxane)s with α,ω‐diaminoalkanes: The cure behavior and film properties (2004)

Abstract A series of nine films were prepared via phenol‐catalyzed thermal crosslinking reactions of 1,9‐bis‐ [glycidyloxypropyl]pentasiloxanes {1,9‐bis[glycidyloxypro‐ pyl]decamethylpentasiloxane (I), 1,9‐bis[glycidyloxypropyl]‐3,5,7‐tris(3′,3′,3′‐trifluoropropyl)heptamethylpentasiloxane (II), and 1,9‐bis[glycidyloxypropyl]‐3,5,7‐tris( 1 ′ H ,1 ′ H,2 ′ H , 2 ′ H ‐perfluorooctyl)heptamethylpentasiloxane (III)} with α,ω‐diaminoalkanes [1,6‐diaminohexane (a), 1,8‐diaminooctane (b), and 1,12‐diaminododecane (c)]. The crosslink density was controlled by the choice of a–c. The cure behavior of I–III with a–c was studied with differential scanning calorimetry. The mechanical properties of the films were determined by dynamic mechanical thermal analysis. Their thermal stability was analyzed by thermogravimetric analysis. The surface properties of the films were evaluated with static contact‐angle measurements. These films represented a novel class of epoxies with an unusual combination of properties: high flexibility (low glass‐transition temperature), good thermal stability, and hydrophobic surfaces. © 2004 Wiley Periodicals, Inc.

A sixteen channel peak sensing ADC for singles spectra in the FERA format (1996)

To read out multi-element small X-ray detectors for X-ray fluorescence applications with synchrotron radiation one needs the capability to record multiple singles spectra for each detector element at high rates. We have developed a sixteen channel 11 bit peak sensing ADC in a CAMAC module. We use the FERA readout bus to place the data into a commercially available histogramming module developed to generate multiple histograms from FERA ADCs. The sixteen channels digitize shaped pulses from the detectors without external gating. The digitizing time is 8 /spl mu/sec, the peak acquisition time is /spl ges/2 /spl mu/sec. The module contains a LIFO to permit block transfers in order to minimize dead times associated with the readout. There is a common CAMAC controlled analog threshold for noise suppression and a 16 bit mask to enable or disable individual ADCs. Differential non linearity is less than +8%/-4%. A /spl gamma/-ray spectrum collected using this ADC is presented.
Energy Efficiency Fairness Beamforming Designs for MISO NOMA Systems (2019)

In this paper, we propose two beamforming designs for a multiple-input single-output non-orthogonal multiple access system considering the energy efficiency (EE) fairness between users. In particular, two quantitative fairness-based designs are developed to maintain fairness between the users in terms of achieved EE: max-min energy efficiency (MMEE) and proportional fairness (PF) designs. While the MMEE-based design aims to maximize the minimum EE of the users in the system, the PF-based design aims to seek a good balance between the global energy efficiency of the system and the EE fairness between the users. Detailed simulation results indicate that our proposed designs offer many-fold EE improvements over the existing energy-efficient beamforming designs.
Early infection of scutellum tissue with Agrobacterium allows high‐speed transformation of rice (2006)

Several approaches have recently been adopted to improve Agrobacterium-mediated transformation of rice, both to generate the large number of T-DNA insertion plants needed for functional analysis of the rice genome, and for production of rice with additional agronomical value. However, about 3 months of in vitro culture is still required for isolation of transgenic rice plants. Here, we report the competency of scutellum tissue from 1-day pre-cultured seeds for Agrobacterium-mediated transformation. Furthermore, early infection of rice seeds with Agrobacterium enhanced efficient selection of transformed calli. Using our system, we successfully regenerated transgenic rice plantlets within a month of the start of the aseptic culture of mature seeds. Our new system should reduce the somaclonal variation accompanying prolonged culture of rice cells in the dedifferentiated state and facilitate the molecular breeding of rice.
Flooding With Network Coding Under a Schedule-Based Spanning Tree in Low-Duty-Cycle Wireless Sensor Networks (2017)

Flooding under a schedule-based spanning tree is an appropriate scheme in low-duty-cycle wireless sensor networks. The broadcast nature of wireless radio can be utilized by scheduling nodes with a common parent to simultaneously wake up. In this letter, we propose a flooding scheme with network coding under a schedule-based spanning tree. The proposed scheme utilizes network coding to maximize the benefit of overhearing from the multiple neighbor nodes of a receiver. A receiver determines which neighbor nodes can provide innovative encoded packets, and, then, selects an optimal overhearing node set with a limited cardinality. The optimal set can maximize the benefit of overhearing while guaranteeing low duty cycle of the receiver. Simulation results show that our proposed scheme outperforms existing schemes in terms of broadcast delay and energy consumption.
Theory of Grease Lubrication of Cylindrical Rooler Bearing (1960)

The lubrication theory on substances of rheological behaviour as grease is a recent theme. In particular, as the grease is often used for the lubrication of roller bearing, it is important to establish a theory of grease lubrication for roller bearings. In this paper, considering grease as a Bingham plastic, a theory of grease lubrication for cylindrical roller bearing has been advanced. The special core formation in grease film, the frictional resistance of roller bearing, the pressure distribution and the load capacity of grease film entrapped between roller and race of cylindrical roller bearing have been investigated.
Multiple aperture optical imaging (1986)

The effect of multiple aperture systems on coherent and incoherent optical imaging was analyzed. Most of the effort was concentrated on the coherent imaging case. A computer program was developed that predicted the images of several simple objects as viewed through various types of multiple aperture. Objects such as edges, bars, and circles were chosen since more complicated objects can be thought of as a collection of these simple objects. These multiaperture images were produced and photographed in the laboratory. The photographs and the computer-generated plots are then analyzed to determine how the spacing, size, and number of subapertures affect the image. These images are compared and contrasted to determine what information can be obtained from them. Essential information, such as shape, orientation, position, and dimensions of the object, was looked for. Finally, the effects of the same multiple apertures on incoherent imaging are studied, and the results are compared with those of the coherent case.
Afferent-inherent regulation of myosin heavy chain isoforms in rat muscle spindles (1997)

Whether afferents exert their morphogenetic influence on spindles through release of trophic factors at intrafusal fiber junctions or via participation in proprioceptive pathways which modulate the motor activity to muscles was investigated by comparing myosin heavy chain (MHC) expression in intrafusal fibers after ablation of afferents (deafferentation, or DA) to the extensor digitorum longus (EDL) of adult rats or after ablation of the corresponding central processes of afferents to the spinal cord (central-process ablation, or CPA). DA and CPA elicited an exaggerated pedal plantarflexion, and hypertrophy of the EDL concomitant with atrophy of the soleus in the affected hindlimb. Frequencies and patterns of expression of seven MHCs expressed by intrafusal fibers in CPA muscles were indistinguishable from normal rats. However, frequencies and patterns of expression of several MHCs were abnormal following DA. Thus factors transported anterogradely from afferents to intrafusal fibers may regulate MHC expression in intrafusal fibers.
Permissive role of reduced inwardly-rectifying potassium current density in the automaticity of the guinea pig pulmonary vein myocardium (2017)

The electrophysiological properties underlying the automaticity of the guinea pig pulmonary vein myocardium were studied. About 30% of the isolated pulmonary vein tissue preparations showed spontaneous electrical activity, as shown by glass microelectrode recordings from their myocardial layer. The remaining quiescent preparations had a resting membrane potential less negative than that in the left atria. Blockade of the acetylcholine activated potassium current (I<sub>K-ACh</sub>) by tertiapin induced a depolarizing shift of the resting membrane potential and automatic electrical activity in the pulmonary vein, but not in the atria. The tertiapin-induced electrical activity, as well as the spontaneous activity, was inhibited by the application of carbachol or by chelation of intracellular Ca<sup>2+</sup> by BAPTA. The isolated pulmonary vein cardiomyocytes had an I<sub>K-ACh</sub> density similar to that of the atrial cardiomyocytes, but a lower density of the inwardly-rectifying potassium current (I<sub>K1</sub>). Spontaneous Ca<sup>2+</sup> transients were observed in about 30% of the isolated pulmonary vein cardiomyocytes, but not in atrial cardiomyocytes. The Ca<sup>2+</sup> transients in the pulmonary vein cardiomyocytes were induced by tertiapin and inhibited by carbachol. These results indicate that the pulmonary vein cardiomyocytes have a reduced density of the inwardly-rectifying potassium current, which plays a permissive role in their intracellular Ca<sup>2+</sup>-dependent automaticity.
Amplification or obfuscation: Is localization improving our clinical understanding of phosphorus metabolism? (1989)

Localization techniques are considered an indispensable part of the clinical spectroscopy examination. The results are often a marked improvement in diagnostic information (amplification), but because of the introduction of new artifacts and the more prolonged examination time, some of the undoubted advantage is lost (obfuscation). There is thus an argument for continued development of more rapid methods of clinical spectroscopy and, if necessary, sacrificing some spatial information.
Allele exchange at the EPSPS locus confers glyphosate tolerance in cassava (2017)

Effective weed control can protect yields of cassava (Manihot esculenta) storage roots. Farmers could benefit from using herbicide with a tolerant cultivar. We applied traditional transgenesis and gene editing to generate robust glyphosate tolerance in cassava. By comparing promoters regulating expression of transformed 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) genes with various paired amino acid substitutions, we found that strong constitutive expression is required to achieve glyphosate tolerance during in vitro selection and in whole cassava plants. Using strategies that exploit homologous recombination (HR) and nonhomologous end-joining (NHEJ) DNA repair pathways, we precisely introduced the best-performing allele into the cassava genome, simultaneously creating a promoter swap and dual amino acid substitutions at the endogenous EPSPS locus. Primary EPSPS-edited plants were phenotypically normal, tolerant to high doses of glyphosate, with some free of detectable T-DNA integrations. Our methods demonstrate an editing strategy for creating glyphosate tolerance in crop plants and demonstrate the potential of gene editing for further improvement of cassava.

Use of a bottle warmer to increase 4% sodium hypochlorite tissue dissolution ability on bovine pulp (2008)

The aim of this study was to evaluate the tissue dissolution ability of 4% sodium hypochlorite at increasing temperatures with the use of a baby bottle warmer. Twenty pieces of bovine pulp tissue from freshly extracted incisors and canines were weighted and randomly distributed among four groups in accordance to the exposure to 4% sodium hypochlorite at different temperatures: group C--room temperature (20.5 degrees C--control); group T1--45 degrees C; group T2--60 degrees C; group T3--75 degrees C. The samples were placed within test tubes when the solution reached the desired temperature. Time taken for the dissolution was recorded. One-way anova with logarithmical transformation and Duncan post-hoc was used (P = 0.05). There was a statistically significant increase in speed of pulp dissolution from group T1 to group C and from groups T2 and T3 to group T1; group T2 and T3 displayed similar dissolution speeds.
Artery-vein separation via MRA-An image processing approach (2001)

This paper presents a near-automatic process for separating vessels from background and other clutter as well as for separating arteries and veins in contrast-enhanced magnetic resonance angiographic (CE-MRA) image data, and an optimal method for three-dimensional visualization of vascular structures. The separation process utilizes fuzzy connected object delineation principles and algorithms. The first step of this separation process is the segmentation of the entire vessel structure from the background and other clutter via absolute fuzzy connectedness. The second step is to separate artery from vein within this entire vessel structure via iterative relative fuzzy connectedness. After seed voxels are specified inside artery and vein in the CE-MRA image, the small regions of the bigger aspects of artery and vein are separated in the initial iterations, and further detailed aspects of artery and vein are included in later iterations. At each iteration, the artery and vein compete among themselves to grab membership of each voxel in the vessel structure based on the relative strength of connectedness of the voxel in the artery and vein. This approach has been implemented in a software package for routine use in a clinical setting and tested on 133 CE-MRA studies of the pelvic region and two studies of the carotid system from six different hospitals. In all studies, unified parameter settings produced correct artery-vein separation. When compared with manual segmentation/separation, our algorithms were able to separate higher order branches, and therefore produced vastly more details in the segmented vascular structure. The total operator and computer time taken per study is on the average about 4.5 min. To date, this technique seems to be the only image processing approach that can be routinely applied for artery and vein separation.
Thermal and acoustic experiments on polymorphic ethanol (2008)

Abstract\n We report calorimetric and acoustic experiments conducted on pure ethanol, in the temperature range around 80 ? 180 K, where different solid-solid and solid-liquid transitions are observed. Using a versatile calorimetric experimental system, we have accurately measured the specific heat of the different phases, and also studied the phase transitions between them, the latter supported by complementary Brillouin-scattering experiments. The influence of several factors in the kinetics of crystallization vs vitrification is also shown and briefly discussed.
Bioinformatic and mass spectrometry identification of Anaplasma phagocytophilum proteins translocated into host cell nuclei (2015)

Obligate intracellular bacteria have an arsenal of proteins that alter host cells to establish and maintain a hospitable environment for replication. Anaplasma phagocytophilum secrets Ankyrin A (AnkA), via a type IV secretion system, which translocates to the nucleus of its host cell, human neutrophils. A. phagocytophilum-infected neutrophils have dramatically altered phenotypes in part explained by AnkA-induced transcriptional alterations. However, it is unlikely that AnkA is the sole effector to account for infection-induced transcriptional changes. We developed a simple method combining bioinformatics and iTRAQ protein profiling to identify potential bacterial-derived nuclear-translocated proteins that could impact transcriptional programming in host cells. This approach identified 50 A. phagocytophilum candidate genes or proteins. The encoding genes were cloned to create GFP fusion protein-expressing clones that were transfected into HEK-293T cells. We confirmed nuclear translocation of six proteins: APH_0062, RplE, Hup, APH_0382, APH_0385, and APH_0455. Of the six, APH_0455 was identified as a type IV secretion substrate and is now under investigation as a potential nucleomodulin. Additionally, application of this approach to other intracellular bacteria such as Mycobacterium tuberculosis, Chlamydia trachomatis and other intracellular bacteria identified multiple candidate genes to be investigated.
Sharing Context-Aware Road and Safety Information (2009)

We present an integrated vehicular system for the collection, management, and provision of context-aware information on traffic and driver location. This system uses an integrated vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication paradigm enriched with an information management system. The infrastructure manages vehicle-detected safety hazards and other relevant information, adapting them to the vehicle's context and driver's preferences. This vehicular integrated system resembles the concept of a smart road.
