Abstract:
Introduction: The risk of developing deep vein thrombosis (DVT) is high even after the period of bed rest following major general surgery including total joint arthroplasty (TJA). Mobile intermittent pneumatic compression (IPC) devices allow the application of IPC during postoperative exercise. Although ambulation included ankle movement, no reports have been made regarding the effects of IPC during exercise, including active ankle exercise (AAE), on venous flow. This study was performed to examine whether using a mobile IPC device can effectively augment the AAE-induced increase in peak velocity (PV). Methods: PV was measured by Doppler ultrasonography in the superficial femoral vein at rest, during AAE alone, during IPC alone, and during AAE with IPC in 20 healthy subjects in the sitting position. PV in AAE with IPC was measured with a mobile IPC device during AAE in the strong compression phase. AAE was interrupted from the end of the strong compression phase to minimize lower limb fatigue. Results: AAE with IPC (76.2 cm/s [95%CI, 69.0–83.4]) resulted in a significant increase in PV compared to either AAE or IPC alone (47.1 cm/s [95%CI, 38.7–55.6], p < 0.001 and 48.1 cm/s [95%CI, 43.7–52.4], p < 0.001, respectively). Discussion: Reduced calf muscle pump activity due to the decline in ambulation ability reduced venous flow. Therefore, use of a mobile IPC device during postoperative rehabilitation in hospital and activity including self-training in an inpatient ward may promote venous flow compared to postoperative exercise without IPC. Conclusion: Use of a mobile IPC device significantly increased the PV during AAE, and simultaneous AAE with IPC could be useful evidence for the prevention of DVT in clinical settings, including after TJA.

Abstract:
Recent mechatronic systems, such as inspection machines or 3D imaging apparatuses, acquire and compute massive data for final results. A host in the mechatronic system is commonly composed of multiple hardware devices which interface with high-speed external signals. The host and the devices usually have large memory, so efficient data management is important due to data storage and transfer. In our software structure, each device is managed by respective application and large shared memory (LSM) is allocated in the host for the massive data. The shared memory is accessible from the device applications. Actions of the mechatronic system are driven by combining and broadcasting events through and inter-process communication (IPC). The model with LSM and IPC was applied to a 3D RF imaging system. We expect the proposed model can also be applied to machine vision with big image and engineering simulation with hardware accelerators.

Abstract:
We conducted a prospective study of cancer patients to investigate the efficacy, quality of life, satisfaction, and safety of a home-based intermittent pneumatic compression (IPC) device during the maintenance phase of lower extremity lymphedema. This device has a unique mode designed to mimic the manual lymphatic drainage (MLD) technique and thereby gently facilitate lymphatic draining of proximal extremities. Thirty patients with stage 3 chronic secondary unilateral leg lymphedema in the maintenance phase underwent IPC and conventional compression therapy for 4 weeks at home. The participants were guided to use 1 h course (30 min of MLD-mimicking mode and 30 min of conventional mode) of IPC device twice a day for 4 weeks. We assessed the patients’ limb-volume measurement, quality of life (QOL), and satisfaction four times. There were no significant time-dependent interactions in the inter-limb volume difference ratio (Vratio). In a subgroup analysis, participants who used the home-based IPC device and maintained their routine self-maintenance program of short-stretch bandages (group B, n = 21) showed a more significant decline in Vratio than those who did not maintained their routine care (group A, n = 9). All scores of QOL decreased significantly after the intervention without subgroup difference. All participants were satisfied with the 4-week intervention. This study demonstrated that a home-based IPC device with an MLD-mimicking program is a useful option for maintaining the volume of limbs and improving the QOL of patients with stage 3 chronic leg lymphedema during the maintenance phase.

Abstract:
Objective: Intermittent pneumatic compression (IPC) is an alternative method of compression treatment designed to compress the leg and mimic ambulatory pump action to actively promote venous return. This study explores the efficacy of a new portable IPC device on tissue oxygenation (StO2) in two sitting positions. Method: In this quantitative, healthy single cohort study, participants were screened and recruited using Physical Activity Readiness Questionnaire (PAR-Q, Canada). Participants attended two separate one-hour sessions to evaluate StO2 in an upright chair-sitting position and in a long-sitting position. StO2 was recorded for 20 minutes before, during and after a 20-minute intervention of the IPC device (Venapro, DJO Global, US). Results: A total of 29 healthy volunteers took part in the study. A significant difference was seen between the two seating positions (p=0.003) with long-sitting showing a 12% higher StO2 level than chair-sitting post-intervention. A similar effect was seen in both sitting positions when analysing data over three timepoints (p=0.000). Post-hoc pairwise comparisons showed that significant improvements in StO2 (p≤0.000) were seen from baseline, throughout the intervention, continuing up to 15 minutes post-intervention, indicating a continued effect of the device after a short intervention. Conclusion: Increasing StO2 through short intervention sessions with this portable device has potential for use within various health and sports-based practices, improving tissue health, potentially reducing postoperative deep vein thrombosis (DVT) risk or inflammation. Such devices lend themselves to wide self-management implementation.

Abstract:
Intermittent pneumatic compression (IPC) is a proactive compression therapeutic technique in the prophylaxis of deep vein thrombosis, reduction of limb edema, and treatment of chronic venous ulcers. To appropriately detect and analyze biomechanical pressure profiles delivered by IPC in treatment, a dynamic interface pressure monitoring system was developed to visualize and quantify morphological pressure mapping in the spatial and temporal domains in real time. The system comprises matrix soft sensors, a smart IPC device, a monitoring and analysis software, and a display unit. The developed soft sensor fabricated by an advanced screen printing technology was used to detect intermitted pressure by an IPC device. The pneumatic pressure signals inside the bladders of the IPC were also transiently collected by a data acquisition system and then transmitted to the computer through Bluetooth. The experimental results reveal that the developed pressure monitoring system can perform the real-time detection of dynamic pressures by IPC and display the morphological pressure mapping multi-dimensionally. This new system provides a novel modality to assist in the effective evaluation of proactive compression therapy in practice. The study results contribute to understanding the working mechanisms of IPC and improving its functional design based on intuitive biomechanical characteristics of compression delivery profiles.

Abstract:
Clinical Scenario: Endurance sports require a great deal of physical training to perform well. Endurance training and racing stress the skeletal muscle, resulting in exercise-induced muscle damage (EIMD). Athletes attempt to aid their recovery in various ways, one of which is through compression. Dynamic compression consists of intermittent pneumatic compression (IPC) devices, such as the NormaTec Recovery System and Recovery Pump. Clinical Question: What are the effects of IPC on the reduction of EIMD in endurance athletes following prolonged exercise? Summary of Key Findings: The current literature was searched to identify the effects of IPC, and 3 studies were selected: 2 randomized controlled trials and 1 randomized cross-over study. Two studies investigated the effect of IPC on delayed onset muscle soreness and plasma creatine kinase in ultramarathoners. The other looked at the impact of IPC on delayed onset muscle soreness in marathoners, ultramarathoners, triathletes, and cyclists. All studies concluded IPC was not an effective means of improving the reduction of EIMD in endurance-trained athletes. Clinical Bottom Line: While IPC may provide short-term relief of delayed onset muscle soreness, this device does not provide continued relief from EIMD. Strength of Recommendation: In accordance with the Strength of Recommendation Taxonomy, the grade of B is recommended based on consistent evidence from 2 high-quality randomized controlled trials and 1 randomized cross-over study.

Abstract:
Ischemic preconditioning (IPC) is a well-documented phenomenon. Short episodes of sublethal ischemia provide cardioprotective effects for subsequent longer duration ischemic events. Although the exact mechanism of IPC is not yet known, the chemical basis of IPC seems to involve preservation of ATP or collateral vascularization recruitment. In this case report, we present visual evidence of ischemic preconditioning using Heartscape Technologies 80 Lead ECG device. The 80 Lead ECG is described as a body surface mapping modality, converting its inputted 80 lead ECG data into a 3-Dimensional color coded map. The 80 lead ECG device can detect instantaneous ischemic changes. Different studies have been performed to show different clinical and biochemical aspects of IPC. However data regarding direct visual evidence of this phenomenon is lacking. The secondary objective of this study is to show the ability of 80 lead ECG to identify ST-segment elevation and depression during ischemic events. The utility of 80 Lead ECG body surface mapping is enormous when evaluating ischemic events.

Abstract:
Abstract Periocular biometrics is a relatively new field of research, and only several publications on this topic can be found in the literature. It can become a promising feature that can be used independently or as a complement to other biometrics. In this work, the recognition rates of periocular biometrics on a single acquisition device and inter-device database is verified and the impact of different image sources on the performance of recognition algorithms is investigated. For this purpose a NearInfrared Light database was collected. The database contains images taken by two acquisition devices. In order to test the periocular biometric trait, three feature extraction methods are chosen: Histograms of Oriented Gradients, Local Binary Patterns and Scale Invariant Feature Transform. The fusion of these methods is also proposed and it is tested on inter-device database. The feasibility of applying periocular recognition as an individual decision module for a biometric system is assessed. Experimental results yield Equal Error Rate of 17.65 for right eye using inter-device database of 640 gallery periocular images for each eye side taken from 32 different individuals (20 images per individual for each eye side). These results are obtained by the optimal weighted sum fusion of the three feature extraction methods.

Abstract:
In this thesis, the whole process of design a low pass filter (LPF) for the wireless communication application has been presented. Integrated passive device technology based on GaAs substrate has been utilized to make the LPF. Schematic simulation and electromagnetic simulations are extensively used in the design process. EM simulation is used in the selection of layout design and processing parameters for design optimization of both the inductors and IPD harmonic filters. The effective use of EM simulation enables us to realize the successful development of high performance harmonic filters. To make the optimization be more flexible and also for a deeper understanding of the optimization theory, optimization using genetic algorithm is also implemented. The weight of each targets are adjustable, and a non-uniformly distributed goal for the harmonic rejection range is introduced to achieve better optimization results. The embedded LPF is built and measurement results show good agreement with the simulation data. This kind of very compact, high performance harmonic filters can be used in radio transceiver front-end modules. The realized harmonic filters have insertion loss less than 0.6 dB and harmonic rejections greater than 25 dB with a compact die size of 0.8 mm2.

Abstract:
Motor control assets are foundational elements in many industrial operations. In the mining industry, these assets primarily consist of motor control centers and drives, which are available with a comprehensive assortment of control and monitoring devices. Various intelligent electronic devices (IEDs) are now used to prevent machine damage and downtime. As motor control devices have advanced in technology, so too have the IEDs that protect them. These advances have resulted in new standards, such as IEC 61850, that have embedded intelligence and a standard set of communication schemes by which IEDs can share information in a peer-to-peer or one-to-many fashion. This dissertation investigated the steps involved in interfacing IEDs to a mining process control network via the use of the IEC 61850 standard. As a result of this study, several key technological advancements were made including the development of (i) vendor independent system to communicate with IEDs in a mining environment over IEC 61850, (ii) command and control methods for communication based assisted automation of IEDs for mining firms, (iii) effective solutions to incorporate electrical distribution data in the process control system, (iv) enhanced safety platforms through remote operation of IEDs, (v) standard visualization faceplate graphics for HMI operators with enhanced security, and (vi) new methods for time stamped dataflow to be correctly inserted into a process historian for 'true' Sequence of Events Records.

Abstract:
La complexité des systèmes RF intégrés pour les applications sans fil grand public s’accroit, et exige de revisiter l’intégration des circuits passifs RF et microondes. De nouvelles solutions offrant plus de compacité et de performance doivent être recherchées, avec un coût de fabrication qui doit rester faible. Parmi celles-ci, une filière technologique 3D de type « Integrated Passive Devices » (IPD) est développée au LAAS CNRS et par la société 3DiS Technologies depuis plusieurs années. Après avoir démontré les capacités de la technologie pour l’intégration de solénoïdes extrêmement compacts et performants, le travail présenté dans ce manuscrit ajoute l’intégration des condensateurs pour faire évoluer la technologie vers la fabrication de fonctions passives RF complexes.Le manuscrit s’articule en trois chapitres. Une première partie dresse une revue des procédés technologiques existants pour la fabrication de systèmes RF et met en évidence l’importance de disposer de composants passifs compacts et performants pour pouvoir intégrer les circuits MMIC. Dans ce contexte, nous présentons les avantages apportés par une solution d’intégration 3D bas coût telle que celle proposée. Dans une deuxième partie, nous présentons le développement de condensateurs Métal Isolant Métal (MIM). Les caractérisations montrent que les condensateurs présentent des performances équivalentes à celles recensées dans la littérature avec de très bons coefficients de qualités. Nous appliquons ensuite la technologie 3D complète à la réalisation de deux transformateurs adaptés en impédance 50 ohms en utilisant des condensateurs. Le procédé technologique de fabrication des deux circuits est décrit. Dans la bande d’adaptation, les circuits fabriqués et caractérisés affichent des pertes en transmission équivalentes aux pertes théoriques minimales estimées à partir du gain disponible maximum des transformateurs. Ces résultats confirment les bonnes performances des condensateurs MIM développés qui introduisent des pertes minimes pour les circuits fabriqués. Aucun problème de fabrication n’est relevé pour les transformateurs adaptés, ce qui permet de valider le procédé technologique complet pour l’intégration de condensateurs et de solénoïdes.Sur la base de ces résultats, le dernier chapitre est consacré au développement d’une matrice de Butler 4×4 destinée à piloter un faisceau de quatre éléments rayonnants en visant la 5G comme contexte applicatif. Des pertes en transmissions inférieures à 3,5 dB et un écart sur les déphasages en sorties de 16° sont relevés pour une large bande passante de 24 GHz à 29 GHz. Ces résultats de mesure sont à l’état de l’art et surpassent les solutions existantes, en particulier au niveau de la surface occupée de seulement 0,84 mm2. Ces résultats démontrent le potentiel de la technologie 3D à réaliser un compromis innovant entre densité d’intégration et performances
The complexity of embedded RF systems in consumer wireless applications is increasing, and requires to improve the integration of RF and microwave passive circuits. New solutions that offer more compactness and performance have to be developed, while maintaining a low manufacturing cost. Among Integrated Passive Devices (IPD) technologies, a 3-D technology has been developed at the LAAS CNRS and by 3DiS Technologies for several years. Results demonstrate that the manufactured solenoids exhibit high compactness and high-performance. This PhD thesis aims to develop the integration process of capacitors in order to evolve the technology towards the fabrication of complex passive RF functions.The manuscript is divided into three chapters. The first chapter reviews the technological processes that enable the manufacture of RF systems and highlights the challenges for integrating high-performance passive components. It also presents the advantages of a low-cost 3-D integration solution such as the one proposed. In the second chapter, we present the development of Metal Insulator Metal (MIM) capacitors. The characterization result show that capacitors present performances equivalent to those identified in the literature with high quality factors. We then manufacture two transformers matched to 50 ohms using capacitors. The technological process is described. The manufactured and measured circuits show that transmission losses are close to those obtained at the maximum available gain of the transformers. These results confirm the good performance of the developed capacitors since they introduce minimal losses for the manufactured circuits. No technological problems are encountered during the manufacturing of the two transformers, which validates the complete technological process for the integration of capacitors and solenoid.Based on these results, we present in the last chapter the development of a 4×4 Butler matrix dedicated to 5G beamforming applications. In a large bandwidth ranging from 24 GHz to 29 GHz, insertion losses for the four outputs of the matrix are under 3.5 dB and the phase difference between the outputs are reached with a deviation of less than 16°. The measured results are at the state of the art and overcome those of the existing IPD solutions, in particular for the occupied aera that does not exceed 0.84 mm2. These performances allow us to conclude on the potential of 3-D IPD technology to achieve an excellent compromise between integration density and performance

Abstract:
Abstract The suprachoroidal outflow pathway has the potential to reduce intraocular pressure (IOP) significantly but has been associated with sight-threatening complications including severe and prolonged hypotony. Historically, suprachoroidal devices have been implanted ab externo requiring a conjunctival peritomy and scleral flap dissection. Additionally, the long-term efficacy of previous attempts to harness this space has been disappointing due to occlusion of implanted devices by fibrosis in the suprachoroidal space. More recently, there have been a number of suprachoroidal devices that are injected ab interno., including the CyPass Micro-Stent (Alcon Laboratories Inc., Fortworth, Texas, USA), the iStent Supra (Glaukos Corporation, San Clemente, CA, USA) and the MINIject (iSTAR Medical Isnes, Belgium). These have utilized a clear corneal entry, thereby sparing the conjunctiva. Early results with these ab-interno devices showed safety and efficacy in IOP-lowering that is similar to Schlemm’s canal minimally invasive glaucoma surgery devices and procedures. Despite the ab-interno approach, their long-term efficacy also seems to be limited by fibrosis. In addition, the first commercially available ab-interno suprachoroidal device, the CyPass Micro-Stent, has been voluntarily withdrawn globally by the manufacturer in August 2018, after 5-year follow-up data demonstrated a higher level of endothelial cell loss with the device than in controls. The iStent Supra and MINIject are not yet available commercially.

Abstract:
AbstractGenerally speaking, standards are adopted to reduce transaction costs for several implementers and increase interoperability among devices and platforms. Standards make our lives as consumers easier. For instance, a Wi-Fi-enabled smartphone device will connect to a Wi-Fi connection regardless of the jurisdiction. It has happened because Wi-Fi is a standard, which has been unanimously adopted by all stakeholders. There are technical standards adopted through several standard setting organizations, and there are standards adopted through market demand, which have evolved with time. Standard setting organizations (SSOs) play a crucial role in operationalizing a standard. The stages through which a standard is operationalized are often fraught with uncertainty, and a lot depends on the internal structure of an SSO. The most significant contributor to the entire process is the IPR policies adopted by each of these SSOs. This chapter provides a glimpse of these IPR policies of SSOs in three different jurisdictions, i.e., Europe, the United States, and India. These policies show their diverse nature and often lead to complex end-results.

Abstract:
Laser-induced breakdown spectroscopy (LIBS) is a rapid, low-cost analytical method with potential applications for quantitative analysis of soils for heavy metal contaminants found in military ranges. The Department of Defense (DoD), Army, and Department of Homeland Security (DHS) have mission requirements to acquire the ability to detect and identify chemicals of concern in the field. The quantitative potential of a commercial off-the-shelf (COTS) hand-held LIBS device and a classic laboratory bench-top LIBS system was examined by measuring heavy metals (antimony, tungsten, iron, lead, and zinc) in soils from six military ranges. To ensure the accuracy of the quantified results, we also examined the soil samples using other hand-held and bench-top analytical methods, to include Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and X-Ray Fluorescence (XRF). The effects of soil heterogeneity on quantitative analysis were reviewed with hand-held and bench-top systems and compared multivariate and univariate calibration algorithms for heavy metal quantification. In addition, the influence of cold temperatures on signal intensity and resulting concentration were examined to further assess the viability of this technology in cold environments. Overall, the results indicate that additional work should be performed to enhance the ability of LIBS as a reliable quantitative analytical tool.

Abstract:
The swelling of plant motor cells is regulated by various signals with almost unknown mediators. One of the obligatory steps in the signaling cascade is the activation of K+-influx channels -K+ channels activated by hyperpolarization (KH channels). We thus explored the regulation of these channels in our model system, motor cell protoplasts from Samanea saman, using patch-clamp in the "whole cell" configuration. (a) The most novel finding was that the activity of KH channels in situ varied with the time of the day, in positive correlation with cell swelling: in Extensor cells KH channels were active in the earlier part of the day, while in Flexor cells only during the later part of the day; (b) High internal pH promoted the activity of these channels in Extensor cells, opposite to the behavior of the equivalent channels in guard cells, but in conformity with the predicted behavior of the putative KH channel, cloned from S. saman recently; (c) HIgh external K+ concentration increased (KH channel currents in Flexor cells. BL depolarized the Flexor cells, as detected in cell-attached patch-clamp recording, using KD channels (the K+-efflux channels) as "voltage-sensing devices". Subsequent Red-Light (RL) pulse followed by Darkness, hyperpolarized the cell. We attribute these changes to the inhibition of the H+-pump by BL and its reactivation by RL, as they were abolished by an H+-pump inhibitor. BL increased also the activity KD channels, in a voltage-independent manner - in all probability by an independent signaling pathway. Blue-Light (BL), which stimulates shrinking of Flexor cells, evoked the IP3 signaling cascade (detected directly by IP3 binding assay), known to mobilize cytosolic Ca2+. Nevertheless, cytosolic Ca2+ . did not activate the KD channel in excised, inside-out patches. In this study we established a close functional similarity of the KD channels between Flexor and Extensior cells. Thus the differences in their responses must stem from different links to signaling in both cell types.

Abstract:
Objectives: The Israeli work plan regarding HBTM included: (a) producing a better diagnostic method; (b) following infestations during the season and evaluating damage to resistant bees and, (c) controlling HBTM by conventional means under local conditions. For varroa our plans to try novel control (e.g. oil novel control (e.g. oil patties & essential oils) were initially delayed by very low pest populations, then disrupted by the emergence of fluvalinate resistance. We monitored the spread of resistance to understand it better, and analyzed an underlying biochemical resistance mechanism in varroa. The US work plan focused on novel management methods for both mites with an emphasis on reducing use of traditional insecticides due to resistance and contamination issues. Objectives were: (a) evaluating plant essential oils for varroa control; (b) exploring the vulnerability of varroa to desiccation for their management; and (c) looking for biological variation in HBTM that could explain virulence variability between colonies. Although the initial PI at the USDA Beltsville Bee Lab, W.A. Bruce, retired during the project we made significant strides especially on varroa water balance. Subcontracts were performed by Yoder (Illinois College) on varroa water balance and DeGrandi-Hoffman (USDA) who evaluated plant essential oils for their potential to control varroa. We devised an IPM strategy for mite control i the U.S. Background: Mites that parasitize honey bees are a global problem. They are threatening the survival of managed and feral bees, the well-being of commercial/hobby beekeeping, and due to pollination, the future of some agricultural commodities is threatened. Specific economic consequences of these mites are that: (a) apiculture/breeder business are failing; (b) fewer colonies exist; (c) demand and cost for hive leasing are growing; (d) incidences of bee pathogens are increasing; and, (e) there are ore problems with commercial-reared bees. As a reflection of the continued significance f bee mites, a mite book is now in press (Webster & delaplane, 2000); and the 2nd International Conference on Africanized Honey Bees and Bee Mites is scheduled (April, 2000, Arizona). The first such conference was at OSU (1987, GRN was co-organizer). The major challenge is controlling two very different mites within a colony while not adversely impacting the hive. Colony management practices vary, as do the laws dictating acaricide use. Our basic postulates were that: (a) both mites are of economic importance with moderate to high infestations but not at low rates and, (b) once established they will not be eradicated. A novel strategy was devised that deals with the pests concomitantly by maintaining populations at low levels, without unnecessary recourse to synthetic acaricides. Major Conclusions, Solutions, Achievements: A major recent revelation is that there are several species of "Varroa jacobsoni" (Anderson & Trueman 1999). Work on control, resistance, population dynamics, and virulence awaits knowing whether this is a problem. In the U.S. there was no difference between varroa from three locales in terms of water balance parameters (AZ, MN & PA), which bodes well for our work to date. Winter varroa (U.S.) were more prone to desiccation than during other seasons. Varroa sensitivity to desiccation has important implications for improving IPM. Several botanicals showed some promise for varroa control (thymol & origanum). Unfortunately there is varroa resistance to Apistan in Israel but a resistance mechanism was detected for the first time. The Israel team also has a new method for HBTM diagnosis. Annual tracheal mite population trends in Israel were characterized, which will help in targeting treatment. Effects of HBTM on honey yields were shown. HBTM control by Amitraz was demonstrated for at least 6 months. Showing partial resistance by Buckfast bees to HBTM will be an important IPM tactic in Israel and U.S.

Full text
Abstract:
Pear-feeding psyllids in the genus Cacopsylla (Hemiptera: Psyllidae) are among the most important arthropod pests of pears worldwide. These pests are exceedingly difficult to control, and new management tools are needed. Sex attractantpheromones have been used in IPM programs for pests of pome fruits (especially Lepidoptera), but not as yet for pest Hemiptera. Results of the current project showed that males of two psyllid pests of pears, Cacopsylla bidens (Israel) and Cacopsylla pyricola (North America), use volatile or semi-volatile compounds to locate female psyllids for mating. For both species, the attractants can be collected from the cuticle of females by washing live female psyllids with an appropriate solvent. Analysis of these washes by gas chromatography – mass spectrometry led to the following discoveries: Psyllid cuticles contain a mix of hydrocarbons, straight chain and branched alkanes, and long chain aldehydes The two species have different chemical profiles Chemical profiles change seasonally and with reproductive status Chemical profiles differ between male and reproductive female psyllids Several specific compounds found to be more abundant in attractive females than males were identified and synthesized. Behavioral assays (olfactometer) were then used to determine whether these compounds were attractive to males. Two compounds showed promise as attractants for male psyllids: 7-methylheptacosane (C. bidens) and 13-methylheptacosane (C. pyricola and C. bidens). These are the first sex attractantpheromones identified for any psyllid species. Field tests showed that the chemicals could be used to attract males under orchard conditions, but that effectiveness in the field appeared to be seasonally variable. Future research plans include: (a) test mixtures of compounds; (b) explore seasonality in field response to compounds; (c) determine whether chirality of the two compounds affects their attractiveness; and (d) compare different types of traps and release devices to optimize lure performance.

Full text
Abstract:
Bridges often serve as key links in local and national transportation networks. Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes. Considering the importance of these structures, the associated structural design philosophy is shifting from collapse prevention to maintaining functionality in the aftermath of moderate to strong earthquakes, referred to as “resiliency” in earthquake engineering research. Moreover, the associated construction philosophy is being modernized with the utilization of accelerated bridge construction (ABC) techniques, which strive to reduce the impact of construction on traffic, society, economy and on-site safety. This report presents two bridge systems that target the aforementioned issues. A study that combined numerical and experimental research was undertaken to characterize the seismic performance of these bridge systems. The first part of the study focuses on the structural system-level response of highway bridges that incorporate a class of innovative connecting devices called the “V-connector,”, which can be used to connect two components in a structural system, e.g., the column and the bridge deck, or the column and its foundation. This device, designed by ACII, Inc., results in an isolation surface at the connection plane via a connector rod placed in a V-shaped tube that is embedded into the concrete. Energy dissipation is provided by friction between a special washer located around the V-shaped tube and a top plate. Because of the period elongation due to the isolation layer and the limited amount of force transferred by the relatively flexible connector rod, bridge columns are protected from experiencing damage, thus leading to improved seismic behavior. The V-connector system also facilitates the ABC by allowing on-site assembly of prefabricated structural parts including those of the V-connector. A single-column, two-span highway bridge located in Northern California was used for the proof-of-concept of the proposed V-connector protective system. The V-connector was designed to result in an elastic bridge response based on nonlinear dynamic analyses of the bridge model with the V-connector. Accordingly, a one-third scale V-connector was fabricated based on a set of selected design parameters. A quasi-static cyclic test was first conducted to characterize the force-displacement relationship of the V-connector, followed by a hybrid simulation (HS) test in the longitudinal direction of the bridge to verify the intended linear elastic response of the bridge system. In the HS test, all bridge components were analytically modeled except for the V-connector, which was simulated as the experimental substructure in a specially designed and constructed test setup. Linear elastic bridge response was confirmed according to the HS results. The response of the bridge with the V-connector was compared against that of the as-built bridge without the V-connector, which experienced significant column damage. These results justified the effectiveness of this innovative device. The second part of the study presents the HS test conducted on a one-third scale two-column bridge bent with self-centering columns (broadly defined as “resilient columns” in this study) to reduce (or ultimately eliminate) any residual drifts. The comparison of the HS test with a previously conducted shaking table test on an identical bridge bent is one of the highlights of this study. The concept of resiliency was incorporated in the design of the bridge bent columns characterized by a well-balanced combination of self-centering, rocking, and energy-dissipating mechanisms. This combination is expected to lead to minimum damage and low levels of residual drifts. The ABC is achieved by utilizing precast columns and end members (cap beam and foundation) through an innovative socket connection. In order to conduct the HS test, a new hybrid simulation system (HSS) was developed, utilizing commonly available software and hardware components in most structural laboratories including: a computational platform using Matlab/Simulink [MathWorks 2015], an interface hardware/software platform dSPACE [2017], and MTS controllers and data acquisition (DAQ) system for the utilized actuators and sensors. Proper operation of the HSS was verified using a trial run without the test specimen before the actual HS test. In the conducted HS test, the two-column bridge bent was simulated as the experimental substructure while modeling the horizontal and vertical inertia masses and corresponding mass proportional damping in the computer. The same ground motions from the shaking table test, consisting of one horizontal component and the vertical component, were applied as input excitations to the equations of motion in the HS. Good matching was obtained between the shaking table and the HS test results, demonstrating the appropriateness of the defined governing equations of motion and the employed damping model, in addition to the reliability of the developed HSS with minimum simulation errors. The small residual drifts and the minimum level of structural damage at large peak drift levels demonstrated the superior seismic response of the innovative design of the bridge bent with self-centering columns. The reliability of the developed HS approach motivated performing a follow-up HS study focusing on the transverse direction of the bridge, where the entire two-span bridge deck and its abutments represented the computational substructure, while the two-column bridge bent was the physical substructure. This investigation was effective in shedding light on the system-level performance of the entire bridge system that incorporated innovative bridge bent design beyond what can be achieved via shaking table tests, which are usually limited by large-scale bridge system testing capacities.
