Residual stress formation after re‐contouring of micro‐plasma welded Ti−6Al−4 V parts by means of ball end milling (2017)

Abstract During the regeneration of damaged components such as compressor blades, the weld repair is followed by machining processes. Excess weld material is removed in a cutting process in order to reproduce the final contour. Therefore, both processe have to be considered regarding the resulting surface and functional properties of the repaired component. In this study, bead on plate welds are produced on 10 mm Ti‐6Al‐4 V sheets using micro‐plasma welding with different levels of welding current. They are subsequently re‐contoured via ball end milling using tools of different cutting edge radii. The residual stress depth profile is measured using X‐ray diffractometry. It is shown that the final residual stress depth profile is mainly influenced by the milling process when machining with rounded cutting edges.
Search for Redshifted Annihilation Radiation from the Crab Pulsar (2001)

We present new stringent upper limits to a redshifted e± annihilation radiation line from the Crab pulsar. These upper limits are based on OSSE observations that were optimized for the 400-500 keV range. We have searched for the emission over several different phase intervals of the pulsar light curve. We find no evidence for the redshifted emission at 440 keV reported by the FIGARO team. The typical 3 σ upper limit to phase-averaged flux (i.e., the net flux from the pulsar averaged over the entire light curve) is about 2 × 10-5 photons cm-2 s-1. This value is about a factor of 4 lower than the 3 σ flux reported by the FIGARO team. This result places significant new constraints on some models in which positrons are flowing down toward the surface of the Crab pulsar.
Coupling Coefficient Estimation for Wireless Power Transfer System at Constant Input Power Operation (2019)

Dynamic Wireless Power Transfer (DWPT) system for electric vehicles (EVs) can extend their the driving distance or even provide an infinite driving range. The receiver-side voltage control is considered as one of the methods to achieve maximum transmission efficiency in DWPT system of EVs. Estimation of coupling coefficient is required for this control method. This paper proposes coupling coefficient estimation in wireless power transfer system at constant input power operation to control receiver-side voltage which maximizes transmission efficiency. The simulation and experimental results demonstrate that the proposed estimation method is significant because the estimated coupling coefficient value and the measured value is statistically equal.
Water-soluble magnetic glyconanoparticles based on metal-doped ferrites coated with gold: Synthesis and characterization (2010)

Novel bimetallic superparamagnetic XFe2O4@Au (X = Fe, Mn and Co) nanocrystals of different sizes were synthesized in high-boiling point ether solvent in two steps. Reduction of gold salts on pre-made seeds in the presence of surfactants was performed resulting in the uniform coverage of the seeds. HAADF- and EDXS-STEM elemental mapping indicate the presence of two metals in the same nanocrystal. The apolar solvent-soluble nanoparticles were transferred into water using an amphiphilic linker and different neoglycoconjugates. The as prepared glyco-ferrites are superparamagnetic at room temperature and present comparable or higher transverse relaxivities (T2) than commercial contrast agents like Endorem, Resovist or Sinerem. The carbohydrate coating provides high stability under physiological conditions, low cytotoxicity and lack of immunogenicity. All glyco-ferrites prepared show comparable relaxation times in phantom imaging.
Human Monocyte-Derived Dendritic Cells Exposed to Microorganisms Involved in Hypersensitivity Pneumonitis Induce a Th1-Polarized Immune Response (2013)

Hypersensitivity pneumonitis (HP) is an immunoallergic disease characterized by a prominent interstitial infiltrate composed predominantly of lymphocytes secreting inflammatory cytokines. Dendritic cells (DCs) are known to play a pivotal role in the lymphocytic response. However, their cross talk with microorganisms that cause HP has yet to be elucidated. This study aimed to investigate the initial interactions between human monocyte-derived DCs (MoDCs) and four microorganisms that are different in nature (Saccharopolyspora rectivirgula [actinomycetes], Mycobacterium immunogenum [mycobacteria], and Wallemia sebi and Eurotium amstelodami [filamentous fungi]) and are involved in HP. Our objectives were to determine the cross talk between MoDCs and HP-causative agents and to determine whether the resulting immune response varied according to the microbial extract tested. The phenotypic activation of MoDCs was measured by the increased expression of costimulatory molecules and levels of cytokines in supernatants. The functional activation of MoDCs was measured by the ability of MoDCs to induce lymphocytic proliferation and differentiation in a mixed lymphocytic reaction (MLR). E. amstelodami-exposed (EA) MoDCs expressed higher percentages of costimulatory molecules than did W. sebi-exposed (WS), S. rectivirgula-exposed (SR), or M. immunogenum-exposed (MI) MoDCs (P < 0.05, Wilcoxon signed-rank test). EA-MoDCs, WS-MoDCs, SR-MoDCs, and MI-MoDCs induced CD4(+) T cell proliferation and a Th1-polarized immune response. The present study provides evidence that, although differences were initially observed between MoDCs exposed to filamentous fungi and MoDCs exposed to bacteria, a Th1 response was ultimately promoted by DCs regardless of the microbial extract tested.

Data compression of myoelectric signal—estimation of force and its long‐term monitoring (1989)

Abstract It is desired in medicine and sport science to develop a lightweight and small‐sized measuring device which can estimate the generated force of muscle from a myo‐electric signal and monitor that signal for a long time. The purpose of this study is to develop a data compression method for the myoelectric signal. First, the myoelectric signal is full‐wave rectified and smoothed to extract the generated force (equivalent isometric tension) of the muscle. The smoothing filter was designed based on the measurements of the myoelectric signal and the force in the isometric contraction. Next, the waveform of the signal (FEMG) after a full‐wave rectification and smoothing is encoded by the adaptive delta modulation (ADM), and the result is stored in the memory. The parameters of ADM were determined in the optimal way for the myoelectric signal. FEMG signals were constructed from fast motion such as occurs in sports, usual motion such as walking, and the delay motion of a neural‐diseased patient, at sampling intervals of 24, 48 and 100 ms. The S/N ratios of ADM data were calculated as above 37, 45 and 52 dB, respectively. A portable computer (8‐bit CPU and 64‐kB memory) with the data compression program was constructed which can measure continuously the myoelectric signal of a normal subject for up to 12 hours. The decoded signal agreed well with the original FEMG, indicating the usefulness of the developed data compression method and the measuring system.
HARMONIJSKA ANALIZA TRO FREKVENTNOG ODZIVA SA GLEDIŠTA BROJA ČLANOVA REDA „FFT” TRANSFORMACIJE (2019)

In this paper, a 1D dynamical model with substrate resistance was imposed with three frequencies of displacement amplitudes with two amplitudes with frequencies in the resonant region. If the external excitation is treated as a continuous periodic real function with two variables (the basic oscillation period -the first and the ratio of the frequency of the external excitation and the response of the model -the second) then we can present the final solution of the motion of the 1D model in conjugated complex form. Applying FFT algorithms with MathCAD, the treated displacement amplitudes in the frequency and time domains respect the mapping sugge-sted by the transfer function (I. M.Milii, 2015) and with a smaller number of order members. Computer simulations confirmed that the harmonic response of a 1D dynamic model system can be successfully modeled based on the equivalent solution which shown here.
Extended and miscellaneous applications of atmospheric radars (2016)

In this chapter, we discuss various extended, and in some cases unusual, applications of MST radar. These may be special cases of general MST techniques, or specific applications of the technique applied to special cases, or even quite unusual applications which are a substantial deviation from “normal” MST standard practices. If such a topic fits well in another chapter, it may appear there – if it is somewhat of an exception, or has a sightly unusual methodology, or is not really an operational technique, it may appear here. Polar mesosphere summer echoes are an example of an “extended” application. While the techniques used to study these unusual echoes are really the same as for other MST studies, the unusual physics associated with the scatterers that produce these echoes makes them of particular interest. Lightning study is an example of a slightly “miscellaneous” application, in that the techniques are a little unusual (high PRFs, and the events are very short lived). Meteor study is an example of a slightly non-standard application that has grown into a substantial field all of its own. Differential absorption is a technique developed early in the days of radar in the 1960s and 1970s which has had a rebirth in the last decades, and deserves a brief mention here. Precipitation study with MST radars is a relatively mature field, but is still a secondary application, so is also included here.
Determinants of the short‐term gastric damage caused by NSAIDs in man (2007)

Against a background of COX-1 and COX-2 inhibition, the physicochemical properties of NSAID appear to play an important role in short-term gastric damage.
A quantum ring terahertz detector with resonant tunnel barriers (2009)

The electronic properties of InAs/GaAs quantum rings and the characteristics of resonant tunnel intersubband terahertz detectors with quantum ring active regions have been studied. The electronic states of the quantum rings have been calculated and measured by the capacitance-voltage technique. The detectors exhibit extremely low dark current density values ∼5×10−5, 4.7×10−2, and 3.5×10−1 A/cm2 under a −1 V bias at 4.2, 80, and 300 K, respectively. Three prominent response peaks are observed at ∼6.5, 10, and 12.5 THz up to T=120 K. At 80 K, the responsivity of the peaks varies from 0.07 to 0.02 A/W.
The design, implementation, and evaluation of Jade (1998)

Jade is a portable, implicitly parallel language designed for exploiting task-level concurrency.Jade programmers start with a program written in a standard serial, imperative language, then use Jade constructs to declare how parts of the program access data. The Jade implementation uses this data access information to automatically extract the concurrency and map the application onto the machine at hand. The resulting parallel execution preserves the semantics of the original serial program. We have implemented Jade as an extension to C, and Jade implementations exist for s hared-memory multiprocessors, homogeneous message-passing machines, and heterogeneous networks of workstations. In this atricle we discuss the design goals and decisions that determined the final form of Jade and present an overview of the Jade implementation. We also present our experience using Jade to implement several complete scientific and engineering applications. We use this experience to evaluate how the different Jade language features were used in practice and how well Jade as a whole supports the process of developing parallel applications. We find that the basic idea of preserving the serial semantics simplifies the program development process, and that the concept of using data access specifications to guide the parallelization offers significant advantages over more traditional control-based approaches. We also find that the Jade data model can interact poorly with concurrency patterns that write disjoint pieces of a single aggregate data structure, although this problem arises in only one of the applications.
Evaluating the effectiveness of a single telephone contact as an adjunct to a self-help intervention for smoking cessation in a randomized controlled trial (2008)

This study evaluated the effects of including a single brief prequit telephone counseling session in a self-help program for smoking cessation conducted through the mail, by comparison with the effects of the self-help program alone. Volunteer participants from northwestern Spain (N = 228) were randomly assigned to one of two groups: (a) the self-help-only group (n = 110, mean age = 37.4 years, pretreatment cigarette consumption = 26.5 cigarettes/day) or (b) the telephone-support group (n = 118, mean age = 36.8 years, pretreatment cigarette consumption = 27.7 cigarettes/day). Using a conservative data analysis method (missing data considered as treatment failures), we found that the point-prevalence abstinence rate was significantly higher in the telephone-support group than in the self-help-only group at the end of treatment (44.9% vs. 21.8%) and at the 3-month follow-up (39.0% vs. 26.4%). Likewise, sustained abstinence was significantly higher in the telephone-support group at the 3-month follow-up (33.9% vs. 13.6%), the 6-month follow-up (25.4% vs. 12.7%), and the 12-month follow-up (21.2% vs. 9.1%). The results of this randomized controlled trial indicate that both treatments are an effective aid for smoking cessation, and that a single brief telephone call before the quit date is a low-cost and effective procedure for improving abstinence rates in a mailed self-help program.
Cross talk in nonlinear interference filters: loop narrowing and critical slowing down (1987)

We study theoretically static and dynamic effects of cross talk between two bistable elements in the same interference filter. The nonlinearity is assumed to be thermal. In the steady state we find that an element in the ON state causes a thermal detuning in another in the OFF state, thereby decreasing its threshold power and narrowing its bistable region. We discuss various ON/OFF combinations in terms of interpixel separation. Starting with two elements in the OFF state, transients are studied by switching one of them with a pulse while the other one remains unaddressed. As the separation approaches a critical value from below, the switching time of the second element diverges. We interpret this effect as critical slowing down. Extension of these results to any array is also discussed.

A new species of coelomycetes in genus Pseudorobillarda is described and illustrated.Pseudorobillarda asparagis sp.nov. is a saprophyte isolated from the soil litter of an asparagus field in Quebec, Canada.This fungus is typical of the genus in morphology, but clearly different from other known species in Pseudorobillarda by distinct size and form of conidiomata and paraphyses, and by shape, size, and colour of conidia.Its taxonomic placement is discussed.
Design and Operation of an Islanded Power System with 100% Renewable Energy Supply (2018)

The design concepts for the 1 MW microgrid power system installed at Ameren Illinois's Technology Applications Center are presented. Specifically, the design and operation of the system when the renewable generation capacity is more than 100% of the connected load is discussed. The methods include utilizing a grid-forming battery energy storage inverter to balance load and generation, and utilizing a microgrid controller for detecting a maximum desired state of charge on the battery system and issuing generation curtailment commands to renewable generation assets.
On-chip human microvasculature assay for visualization and quantification of tumor cell extravasation dynamics (2017)

Distant metastasis, which results in >90% of cancer-related deaths, is enabled by hematogenous dissemination of tumor cells via the circulation. This requires the completion of a sequence of complex steps including transit, initial arrest, extravasation, survival and proliferation. Increased understanding of the cellular and molecular players enabling each of these steps is key to uncovering new opportunities for therapeutic intervention during early metastatic dissemination. As a protocol extension, this article describes an adaptation to our existing protocol describing a microfluidic platform that offers additional applications. This protocol describes an in vitro model of the human microcirculation with the potential to recapitulate discrete steps of early metastatic seeding, including arrest, transendothelial migration and early micrometastases formation. The microdevice features self-organized human microvascular networks formed over 4-5 d, after which the tumor can be perfused and extravasation events are easily tracked over 72 h via standard confocal microscopy. Contrary to most in vivo and in vitro extravasation assays, robust and rapid scoring of extravascular cells, combined with high-resolution imaging, can be easily achieved because of the confinement of the vascular network to one plane close to the surface of the device. This renders extravascular cells clearly distinct and allows tumor cells of interest to be identified quickly as compared with those in thick tissues. The ability to generate large numbers of devices (∼36) per experiment further allows for highly parametric studies, which are required when testing multiple genetic or pharmacological perturbations. This is coupled with the capability for live tracking of single-cell extravasation events, allowing both tumor and endothelial morphological dynamics to be observed in high detail with a moderate number of data points.
Early Restitution of Electrocorticogram Predicts Subsequent Behavioral Recovery from Cardiac Arrest (2002)

Previous studies have shown that parameters of EEG restitution reflect the severity of global hypoxic-ischemic brain injury. Here, the hypothesis is tested that patterns of EEG restitution during the first 4 hours predict later behavioral recovery. Time course and correlations between behavior, electrocorticogram (EcoG), and neuronal injury were investigated in a rodent model of asphyctic cardiac arrest. Forty Wistar rats were subjected to 5 minutes of asphyxia and cardiopulmonary resuscitation. Behavior was assessed by repeated scoring of neurodeficits and open field activity until euthanasia at 48 hours. Electrocorticographic bursting occurred at 13.2 +/- 4 minutes after resuscitation. Bursts increased in frequency and duration until the EcoG reverted to a continuous signal. The resuscitation-continuous EcoG interval correlated with the first appearance of spontaneous movements (r = 0.80, P < 0.05). Larger intervals were associated with hyperactivity in the open field at 24 hours (r = 0.61, P < 0.05), indicating a more severe behavioral deficit. Larger intervals were also associated with worse 48-hour neurodeficit scores (P < 0.05). Neuronal damage in the hippocampus correlated with the degree of open field hyperactivity at 14 hours (P < 0.05). These findings demonstrate a close temporal and prognostic relationship between electrical and behavioral recovery after hypoxic-ischemic brain injury.
Reconstructing Critical Paths from Execution Traces (2012)

We consider the problem of constructing critical paths from incomplete information. In general, a directed acyclic graph of tasks with their execution times (i.e., a task graph) is necessary to extract critical paths. We assume, however, that only the set of tasks, and their start and end times are known, e.g., an execution trace in the form of a Gantt chart. This information can be extracted from real machines or from the output of analysis tools, whereas extraction of the exact task graph often is problematic due to imperative modeling formalisms and complicated platform semantics (resource allocation, varying execution speeds). We show that, based on start and end times only, an over- approximation of the critical paths of an unknown task graph can be extracted nevertheless. Furthermore, this approach is generalized to deal with "noisy" execution traces of real machines in which control overhead is present. Finally, we discuss various methods to deal with false positives, and apply our approach to a complex industrial case study.
Conversion of Dorsal from an activator to a repressor by the global corepressor Groucho (1997)

The Dorsal morphogen acts as both an activator and a repressor of transcription in the Drosophila embryo to regulate the expression of dorsal/ventral patterning genes. Circumstantial evidence has suggested that Dorsal is an intrinsic activator and that additional factors (corepressors) convert it into a repressor. These corepressors, however, have previously eluded definitive identification. We show here, via the analysis of embryos lacking the maternally encoded Groucho corepressor and via protein-binding assays, that recruitment of Groucho to the template by protein:protein interactions is required for the conversion of Dorsal from an activator to a repressor. Groucho is therefore a critical component of the dorsal/ventral patterning system.

Scalability in recursively stored delta compressed collections of files (2014)

The archiving and maintenance of vast quantities of data is a key challenge for the current use of information technology. When storing large repositories, possibly mirrored at multiple sites, an archiving system aims to reduce both storage and transmission costs. Delta compression is a key component of many archiving and backup systems. A file may be stored succinctly as a sequence of references to other files in the collection, establishing a dependency relationship between files. On the one hand, exploiting large dependency chains provides excellent compression. On the other hand, if a file is stored compactly, so that it depends on hundreds of other files, then retrieving it from the archive may be very time and resource consuming.

This paper assesses the scalability of delta compression of typical data collections. We use experiments to model and examine the dependency relationship, and quantify the cost of full use of dependencies. We propose strategies to reduce dependencies and yet retain highly effective compression.
