Retracted on May 31, 2024: Managing Heterogeneous and Time-Sensitive IoT Applications through Collaborative and Energy-Aware Resource Allocation (2022)

In the Internet of Things (IoT) environment, the computing resources available in the cloud are often unable to meet the latency constraints of time critical applications due to the large distance between the cloud and data sources (IoT devices). The adoption of edge computing can help the cloud deliver services that meet time critical application requirements. However, it is challenging to meet the IoT application demands while using the resources smartly to reduce energy consumption at the edge of the network. In this context, we propose a fully distributed resource allocation algorithm for the IoT-edge-cloud environment, which (i) increases the infrastructure resource usage by promoting the collaboration between edge nodes, (ii) supports the heterogeneity and generic requirements of applications, and (iii) reduces the application latency and increases the energy efficiency of the edge. We compare our algorithm with a non-collaborative vertical offloading and with a horizontal approach based on edge collaboration. Results of simulations showed that the proposed algorithm is able to reduce 49.95% of the IoT application request end-to-end latency, increase 95.35% of the edge node utilization, and enhance the energy efficiency in terms of the edge node power consumption by 92.63% in comparison to the best performances of vertical and collaboration approaches.

Ramp-rate limitation test results of the Nb/sub 3/Sn Demo Poloidal Coil (DPC-EX) (2002)

As a high-field pulse-poloidal test coil in the development program of superconducting coils for fusion machines, a 1 m-inner diameter superconducting coil named DPC-EX wound with 10 kA Nb/sub 3/Sn cable-in-conduit forced-cooled conductor was fabricated and its various performances were investigated. In its second test, the ramp-rate limitation phenomenon, i.e. the dependence of the coil current at quench on the current ramp speed, was studied in detail and a lot of important data for the design of large pulse coils were achieved.
Blast injuries in children: a mixed-methods narrative review (2019)

Background and significance Blast injuries arising from high explosive weaponry is common in conflict areas. While blast injury characteristics are well recognised in the adults, there is a lack of consensus as to whether these characteristics translate to the paediatric population. Understanding blast injury patterns in this cohort is essential for providing appropriate provision of services and care for this vulnerable cohort. Methods In this mixed-methods review, original papers were screened for data pertaining to paediatric injuries following blasts. Information on demographics, morbidity and mortality, and service requirements were evaluated. The papers were written and published in English from a range of international specialists in the field. Results Children affected by blast injuries are predominantly male and their injuries arise from explosive remnants of war, particularly unexploded ordinance. Blasts show increased morbidity and mortality in younger children, while older children have injury patterns similar to adults. Head and burn injuries represent a significant cause of mortality in young children, while lower limb morbidity is reduced compared with adults. Children have a disproportionate requirement for both operative and non-operative service resources, and provisions for this burden are essential. Conclusions Certain characteristics of paediatric injuries arising from blasts are distinct from that of the adult cohort, while the intensive demands on services highlight the importance of understanding the diverse injury patterns in order to optimise future service provisions in caring for this child blast survivor.
Supramolecular Nanomachines as Stimuli-Responsive Gatekeepers on Mesoporous Silica Nanoparticles for Antibiotic and Cancer Drug Delivery (2019)

Major objectives in nanomedicine and nanotherapy include the ability to trap therapeutic molecules inside of nano-carriers, carry therapeutics to the site of the disease with no leakage, release high local concentrations of drug, release only on demand - either autonomous or external, and kill the cancer cells or an infectious organism. This review will focus on mesoporous silica nanoparticle carriers (MSN) with a large internal pore volume suitable for carrying anticancer and antibiotic drugs, and supramolecular components that function as caps that can both trap and release the drugs on-command. Caps that are especially relevant to this review are rotaxanes and pseudorotaxanes that consist of a long chain-like molecule threaded through a cyclic molecule. Under certain conditions discussed throughout this review, the cyclic molecule can be attracted to one end of the rotaxane and in the presence of a stimulus can slide to the other end. When the thread is attached near the pore opening on MSNs, the sliding cyclic molecule can block the pore when it is near the particle or open it when it slides away. The design, synthesis and operation of supramolecular systems that act as stimuli-responsive pore capping devices that trap and release molecules for therapeutic or imaging applications are discussed. Uncapping can either be irreversible because the cap comes off, or reversible when the cyclic molecule is prevented from sliding off by a steric barrier. In the latter case the amount of cargo released (the dose) can be controlled. These nanomachines act as valves. Examples of supramolecular systems stimulated by chemical signals (pH, redox, enzymes, antibodies) or by external physical signals (light, heat, magnetism, ultrasound) are presented. Many of the systems have been studied <i>in vitro</i> proving that they are taken up by cancer cells and release drugs and kill the cells when stimulated. Some have been studied in mouse models; after IV injection they shrink tumors or kill intracellular pathogens after stimulation. Supramolecular constructs offer fascinating, highly controllable and biologically compatible platforms for drug delivery.
Ultra‐Fast Supercritical Hydrothermal Synthesis of Tobermorite under Thermodynamically Metastable Conditions (2017)

Tobermorite is a fibrillar mineral of the family of calcium silicates. In spite of not being abundant in nature, its structure and properties are reasonably well known because of its interest in the construction industry. Currently, tobermorite is synthesized by hydrothermal methods at mild temperatures. The problem is that such processes are very slow (>5 h) and temperature cannot be increased to speed them up because tobermorite is metastable over 130 °C. Furthermore the product obtained is generally foil-like and not very crystalline. Herein we propose an alternative synthesis method based on the use of a continuous flow reactor and supercritical water. In spite of the high temperature, the transformation of tobermorite to more stable phases can be prevented by accurately controlling the reaction time. As a result, highly crystalline fibrillar tobermorite can be obtained in just a few seconds under thermodynamically metastable conditions.
Morphology‐Dependent Trap Formation in High Performance Polymer Bulk Heterojunction Solar Cells (2011)

Abstract Bulk heterojunction solar cells (BHJs) based on poly[N‐9″‐hepta‐decanyl‐2,7‐carbazole‐ alt ‐5,5‐(4′,7′‐di‐2‐thienyl‐2′,1′,3′‐benzothiadiazole)] (PCDTBT) can have internal quantum efficiencies approaching 100% but require active layers that are too thin to absorb more than ∼70% of the above band gap light. When the active layer thickness is increased so that the cell absorbs more light, the fill factor and open circuit voltage decrease rapidly, so that the overall power conversion efficiency decreases. We find that hole‐traps in the polymer, which we characterize using space‐charge limited current measurements, play an important role in the performance of PCDTBT‐based BHJs and may limit the active layer thickness. Recombination due to carrier trapping is not often considered in BHJs because it is not believed to be a dominant loss mechanism in the “fruit‐fly” P3HT system. Furthermore, we show that in contrast to P3HT, PCDTBT has only weak short‐range molecular order, and that annealing at temperatures above the glass transition decreases the order in the π–π stacking. The decrease in structural order is matched by the movement of hole‐traps deeper into the band gap, so that thermal annealing worsens hole transport in the polymer and reduces the efficiency of PCDTBT‐based BHJs. These findings suggest that P3HT is not prototypical of the new class of high efficiency polymers, and that further improvement of BHJ efficiencies will necessitate the study of high efficiency polymers with low structural order.

MDG-BASED STATE ENUMERATION BY RETIMING AND CIRCUIT TRANSFORMATION (2004)

Multiway Decision Graphs (MDGs) have recently been proposed as an efficient representation for RTL designs. In this paper, we illustrate the MDG-based formal verification technique on the example of the Island Tunnel Controller. We investigate several techniques on how to deal with the nontermination problem of abstract state exploration, including a novel method based on retiming and circuit transformation. We provide comparative experimental results for the verification of a number of properties for the example using two well-known ROBDD-based verification tools, namely, SMV (Symbolic Model Verifier) and VIS (Verification Interacting with Synthesis), and we show the strength of the MDG approach to handling arbitrary data widths.
Selective detection of cavitation bubbles by triplet pulse sequence in high-intensity focused ultrasound treatment (2018)

Acoustic cavitation bubbles are known to enhance the heating effect in high-intensity focused ultrasound (HIFU) treatment. The detection of cavitation bubbles with high sensitivity and selectivity is required to predict the therapeutic and side effects of cavitation, and ensure the efficacy and safety of the treatment. A pulse inversion (PI) technique has been widely used for imaging microbubbles through enhancing the second-harmonic component of echo signals. However, it has difficulty in separating the nonlinear response of microbubbles from that due to nonlinear propagation. In this study, a triplet pulse (3P) method was investigated to specifically image cavitation bubbles by extracting the 1.5th fractional harmonic component. The proposed 3P method depicted cavitation bubbles with a contrast ratio significantly higher than those in conventional imaging methods with and without PI. The results suggest that the 3P method is effective for specifically detecting microbubbles in cavitation-enhanced HIFU treatment.
Surface Micropatterning of Uniaxially Oriented Polyethylene Films Using Interference Holography for Strain Sensors (2017)

A new procedure is presented for direct generation of surface micropatterns on uniaxially oriented polyethylene (PE) films using interference holography with a nanosecond pulsed laser. An ultraviolet absorber, 2-(2H-benzotriazol-2-yl)-4,6-di-tert-pentylphenol (BZT) is incorporated into PE prior to stretching to generate absorption at the wavelength of the laser. Illumination with an interference pattern in the absorption band of BZT leads to an obvious height variation in the exposed regions and consequently relief gratings are generated. The height in the exposed regions is strongly dependent on the angle between the grating direction and the film orientation direction. This phenomenon is attributed to a combination of events such as melting, entropic contraction, recrystallization, thermal evaporation of BZT, and anisotropic thermal conductivity. It is shown that the relief height increases with increasing BZT concentration and exhibits a linear dependence on the energy dose above a certain threshold. Additionally, the oriented PE films with the surface micropatterns are explored for strain sensors. The results demonstrate that small strains below 10% are monitored accurately in tensile deformation of the micropatterned, oriented PE films which makes these films potentially useful as strain sensors.
Binding of Cd to metallothionein in the placenta of Cd-treated mouse. (1996)

The toxicological significance of the placental metallothionein (MT) was studied from the viewpoint of cadmium (Cd) intoxication. The Cd concentration was higher in the placenta than the kidneys until 8 hr after a single injection of 109CdCl2, but was very low after administration of 109Cd-MT. Compared with lower doses, fetal Cd began to increase at the dose of 2 mg/kg. Alkaline phosphatase activity in the placenta was significantly decreased, and dead fetuses appeared at this dose. The MT concentration was not increased by the Cd injection but the ratio of Cd/Zn in MT increased proportionally to the dose up to 2 mg/kg. MT was detected in the placenta during all stages of pregnancy, and its concentration was higher in the earlier stage. The metal bound to MT was mainly Zn, and very little Cu was bound. In the mice that became pregnant after 109Cd accumulation, redistribution of 109Cd was not observed. MT-I and -II in the placenta were identified by column chromatography and immunoblotting methods. These findings suggest that the placental MT might play a protective role against Cd toxicity by trapping of the metal.

Generation-After-Next Power Electronics: Ultrawide-bandgap devices, high-temperature packaging, and magnetic nanocomposite materials (2017)

A new generation of power electronic conversion systems is being enabled by wide-bandgap (WBG) devices. Applications in both the civilian and defense sectors are already beginning to benefit from the improved size, weight, and power (SWaP) now being demonstrated in power converters utilizing silicon carbide (SiC) and/or gallium nitride (GaN) switches, and numerous manufacturers are offering various types of switching devices fabricated from these two WBG semiconductors.
Effects of the α2/α3-subtype-selective GABAA receptor positive allosteric modulator KRM-II-81 on pain-depressed behavior in rats: comparison with ketorolac and diazepam (2019)

This study examined effects of the α2/α3-subtype-selective GABAA receptor positive allosteric modulator KRM-II-81 in an assay of pain-related behavioral depression. Adult, male Sprague-Dawley rats responded for electrical brain stimulation in a frequency-rate intracranial self-stimulation (ICSS) procedure. Intraperitoneal injection of 1.8% lactic acid served as an acute noxious stimulus to depress ICSS. Effects of KRM-II-81 were evaluated in the absence and presence of the acid noxious stimulus. The NSAID ketorolac and the benzodiazepine diazepam were tested as comparators. Neither ketorolac nor KRM-II-81 altered ICSS in the absence of the acid noxious stimulus; however, diazepam produced facilitation consistent with its abuse liability. Ketorolac blocked acid-induced depression of ICSS, and effects of 1.0 mg/kg ketorolac lasted for at least 5 h. KRM-II-81 (1.0 mg/kg) produced significant antinociception after 30 min that dissipated by 60 min. Diazepam also attenuated acid-depressed ICSS, but only at doses that facilitated ICSS when administered alone. The lack of ketorolac or KRM-II-81 effects on ICSS in the absence of the acid noxious stimulus suggests low abuse liability for both compounds. The effectiveness of ketorolac to block acid-induced ICSS depression agrees with clinical analgesic efficacy of ketorolac. KRM-II-81 produced significant but less consistent and shorter-acting antinociception than ketorolac.

Efficiently-Encodable Rate-Compatible LDPC Codes (2006)

We present a new class of irregular low-density parity-check (LDPC) codes for finite block length (up to a few thousand symbols) that are well-suited for rate-compatible puncturing. The proposed codes are linear-time encodable with a simple shift-register implementation. In addition, the codes show excellent puncturing performance over a wide range of rates with systematic rate-compatible puncturing structure. For a blocklength of 1024 bits the codes outperform optimized irregular LDPC codes and extended irregular repeat-accumulate (eIRA) codes for all rates 0.5~0.9, and are particularly good at high puncturing rates where good puncturing performance has been previously difficult to achieve.
Image structure in Gabor space (1985)

A scheme suitable for image representation in vision is elaborated using a 2-D extension of Bastiaan's work (1980). Investigation of image structure in Gabor space shows that important characteristics of vision are inherent in the scheme, lending itself to image representation by machines. With logarithmic scaling (octave relationship) along the frequency axis, it is shown that certain visual invariances are characteristic of image representation in a combined frequency position space. It appears as though the representation in the combined space captures attractive properties previously shown exclusively for either the position or frequency space. An interesting issue relating to paving of the combined space is concerned with the number of required elementary functions (or channels in vision). It is shown that a trade-off exists between the number of frequency components employed per position and the number of such clusters (sampling rate) utilized along the spatial coordinate. This observation settles arguments against the channel approach in vision, since it shows that a small number of frequency channels can suffice (provided there are enough spatial sampling points). Whereas the analytic solution requires the elaboration of auxiliary functions, it is unlikely that cortical representation employs such operation. We therefore also consider image representation by a set of almost orthogonal functions.
Simulation and Analysis of Unbonded Nonwoven Fibrous Structures (2006)

In this work we report on our algorithm for generating 3–D virtual structures resembling un-bonded fibrous webs. The paper discusses short and infinitely long fibers, each emulating a category of nonwoven fibrous medium. The structure Solid Volume Fraction (SVF), being the most important characteristic of a fibrous porous medium, is calculated for different fiberwebs and discussed in details. It is shown that the SVF of the fibrous structures generated by our algorithm is independent of the basis weight. In other words, the porosity of the medium is only a function of the fiber properties – this is as expected. It is also demonstrated that by decreasing the fiber diameter while keeping other properties of the virtual fiberweb constant causes the SVF to decrease almost linearly. The same is not observed for the fiber rigidity. The capability of our algorithm for generating fibrous webs made up of layers of different fibers is demonstrated and their properties are discussed. The application of such virtual fibrous structures in modeling transport phenomena in nonwoven materials and their potential applications in load-deformation studies are discussed.

Advanced Position Control für Servoachsen (2014)

Strukturelastizitäten und flexible Übertragungsglieder sind der Flaschenhals für die Regelgüte von Servoachsen. Besondere Bedeutung kommt dabei der Einstellung des PI-Geschwindigkeitsreglers zu. In diesem Beitrag werden analytische Einstellregeln für eine optimale Vibrationsdämpfung vorgestellt. Für elastische Antriebsketten gibt es eine Zustandsreglerergänzung von einem führenden Hersteller von Automatisierungskomponenten mit der Bezeichnung Advanced Position Control (APC). Damit lassen sich Lastvibrationen vermindern, wenn die Lastposition ausreichend aufgelöst erfasst wird. Das praxisnahe Vorgehen zur Reglereinstellung an Werkzeugmaschinen wird aufgezeigt und der APC-Ansatz mit einem allgemeineren Konzept der Zustandsreglerergänzung verglichen.
Ni(II) α-Diimine-Catalyzed α-Olefins Polymerization: Thermoplastic Elastomers of Block Copolymers (2015)

The polymerization of ethylene with late transition metal complexes typically provides highly branched amourphous poly(ethylene)s through a chain-walking mechanism, while the chain-straightening polymerization of α-olefins gives semicrystalline polymers. Herein, we report the polymerization of 1-hexene, 1-octene, and 1-dodecene catalyzed by an α-diimine Ni(II) complex in combination with diethylaluminum chloride. The effect of monomer chain length and monomer concentration on the productivity, polymerization “livingness”, selectivity of monomer insertion, and polymer structure/properties is investigated. The polymerization results indicate the possibility of precise microstructure control, depending on the monomer employed and monomer feedstock concentration, which in turn strongly affects the physical polymer properties. Additionally, di- and triblock copolymers were successfully fabricated in an easy, high-yielding route, at room temperature. The synthesis was accomplished through the sequential monomer addition from 1-dodecene and ethylene, without requiring any intermediate separation step. Each block exhibited distinct features from semicrystalline to amorphous, taking advantage of the different mechanism involved in the polymerization of 1-dodecene and ethylene. Investigation on mechanical behavior by uniaxial stretching until failure and step-cycle tensile tests showed that the block copolymers behave as thermoplastic elastomers with different performances depending on the composition, length of the blocks, and crystallinity. We demonstrate that this approach is a route to fabricate thermoplastic elastomers from readily accessible starting materials.
