Generating the Communications Infrastructure for Module-based Dynamic Reconflguration of FPGAs

Current approaches to supporting module-based FPGA reconfiguration focus on various aspects and sub-problems in the area but do not combine to form a coherent, top-down methodology that factors low-level device parameters into every step of the design flow. This thesis proposes such a top-down methodology from application specification to low-level implementation, centered around examining the problem of generating a point-to-point communications infrastructure to support the changing interfaces of dynamically placed modules. Low-level implementation parameters are considered at every stage to ensure that area, timing and budget constraints of the application are met. The approach advocates the regular layout of modules surrounded by a wiring harness supporting the communications for those modules, and thus provides an advanced understanding of how to implement the “fixed wiring harness” model of reconfigurable computing proposed by Brebner. Results have shown that compared to flattened netlists the regularity of the layout does not impose significant overheads on critical path delays. At high communication densities it can even result in lower delays. The core of the methodology is an infrastructure generation process that allocates modules to slots and merges configuration graphs to form wiring harnesses that support the communications for these merged configurations. This thesis suggests methods and evaluates algorithms for configuration graph merging so as to reduce run-time reconfiguration overheads. Initial experiments with a greedy merging algorithm performed on an optical flow application resulted in a substantial reduction of 64% in reconfiguration time. The effects of graph merging with the initial greedy algorithm and an improved dynamic programming algorithm were explored for a range of device sizes and architectural parameters. Results show that configuration merging using the greedy method results in significant reductions to the reconfiguration delay. The dynamic programming algorithm provides consistent improvements above and beyond the savings provided by the greedy method. In addition, a strong correlation was identified between the quality of front-end design activities such as partitioning and the effectiveness of back-end implementations. The methodology is integrated into the Xilinx commercial tool flow for partial reconfiguration, and is effective for implementing applications for module-based FPGA reconfiguration where the modules and their communications requirements are known at design time. It also allows a system designer to consider alternate device sizes and parameters until a set is found that satisfies the application constraints.
Gender-specific associations of short sleep duration with prevalent hypertension.

To the Editor: We read the interesting recent article by Cappuccio et al,1 who found that sleep deprivation was positively associated with hypertension among women. We examined this hypothesis in our ongoing Heinz Nixdorf Recall Study, a prospective population-based cohort study.2,3 Interestingly, we were able to corroborate the gender specificity of the association between short duration of sleep (≤5 hours per night) and prevalence of hypertension, although we observed a weaker association. The age-adjusted prevalence ratio in …
A reference estimator based on composite sensor pattern noise for source device identification

It has been proved that Sensor Pattern Noise (SPN) can serve as an imaging device fingerprint for source camera identification. Reference SPN estimation is a very important procedure within the framework of this application. Most previous works built reference SPN by averaging the SPNs extracted from 50 images of blue sky. However, this method can be problematic. Firstly, in practice we may face the problem of source camera identification in the absence of the imaging cameras and reference SPNs, which means only natural images with scene details are available for reference SPN estimation rather than blue sky images. It is challenging because the reference SPN can be severely contaminated by image content. Secondly, the number of available reference images sometimes is too few for existing methods to estimate a reliable reference SPN. In fact, existing methods lack consideration of the number of available reference images as they were designed for the datasets with abundant images to estimate the reference SPN. In order to deal with the aforementioned problem, in this work, a novel reference estimator is proposed. Experimental results show that our proposed method achieves better performance than the methods based on the averaged reference SPN, especially when few reference images used.
Neural network for quadratic optimization with bound constraints

A recurrent neural network is presented which performs quadratic optimization subject to bound constraints on each of the optimization variables. The network is shown to be globally convergent, and conditions on the quadratic problem and the network parameters are established under which exponential asymptotic stability is achieved. Through suitable choice of the network parameters, the system of differential equations governing the network activations is preconditioned in order to reduce its sensitivity to noise and to roundoff errors. The optimization method employed by the neural network is shown to fall into the general class of gradient methods for constrained nonlinear optimization and, in contrast with penalty function methods, is guaranteed to yield only feasible solutions.
Extracorporeal Shock Wave Therapy in Treatment of Delayed Bone-Tendon Healing

Background Extracorporeal shock wave therapy is indicated for treatment of chronic injuries of soft tissues and delayed fracture healing and nonunion. No investigation has been conducted to study the effect of shock wave on delayed healing at the bone-tendon junction. Hypothesis Shock wave promotes osteogenesis, regeneration of fibrocartilage zone, and remodeling of healing tissue in delayed healing of bone-tendon junction surgical repair. Study Design Controlled laboratory study. Methods Twenty-eight mature rabbits were used for establishing a delayed healing model at the patella–patellar tendon complex after partial patellectomy and then divided into control and shock wave groups. In the shock wave group, a single shock wave treatment was given at week 6 postoperatively to the patella–patellar tendon healing complex. Seven samples were harvested at week 8 and 7 samples at week 12 for radiologic, densitometric, histologic, and mechanical evaluations. Results Radiographic measurements showed 293.4% and 185.8% more new bone formation at the patella–patellar tendon healing junction in the shock wave group at weeks 8 and 12, respectively. Significantly better bone mineral status was found in the week 12 shock wave group. Histologically, the shock wave group showed more advanced remodeling in terms of better alignment of collagen fibers and thicker and more mature regenerated fibrocartilage zone at both weeks 8 and 12. Mechanical testing showed 167.7% and 145.1% higher tensile load and strength in the shock wave group at week 8 and week 12, respectively, compared with controls. Conclusion Extracorporeal shock wave promotes osteogenesis, regeneration of fibrocartilage zone, and remodeling in the delayed bone-to-tendon healing junction in rabbits. Clinical Relevance These results provide a foundation for future clinical studies toward establishment of clinical indication for treatment of delayed bone-to-tendon junction healing.
Relationships among plumage coloration, blood selenium concentrations and immune responses of adult and nestling tree swallows

ABSTRACT In a number of taxa, males and females both display ornaments that may be associated with individual quality and could be reliable signals to potential mates or rivals. We examined the iridescent blue/green back and white breast of adult tree swallows (Tachycineta bicolor) to determine whether plumage reflectance is related to adult or offspring immune responses. We simultaneously addressed the influence of blood selenium levels and the interaction between blood selenium and plumage coloration on adult and nestling immunity. Selenium is a well-known antioxidant necessary for mounting a robust immune response but its importance in wild birds remains poorly understood. In females, the brightness of white breast coloration was positively associated with bactericidal capacity, but there was no association with blood selenium. In contrast, male bactericidal capacity was associated with an interactive effect between dorsal plumage coloration and blood selenium concentration. Males with bluer hues and greater blue chroma showed increased bactericidal capacity as blood selenium concentrations increased, while bactericidal capacity declined in greener males at higher blood selenium concentrations. In nestlings, bactericidal capacity was positively associated with nestling blood selenium concentrations and white brightness of both social parents. These results suggest that white plumage reflectance is indicative of quality in tree swallows and that greater attention should be paid to the reflectance of large white plumage patches. Additionally, the role of micronutrients, such as selenium, in mediating relationships between physiology and signals of quality, should be explored further. Summary: Selenium, an important micronutrient whose influence on the physiology of wild birds is poorly understood, and structural plumage coloration are related to innate immunity in adult and nestling tree swallows.
Industry or Academia, Basic or Applied? Career Choices and Earnings Trajectories of Scientists

We extend life cycle models of human capital investments by incorporating matching theory to examine the sorting pattern of heterogeneous scientists into different career trajectories. We link differences in physical capital investments and complementarities between basic and applied scientists across industry and academic settings to individual differences in scientist ability and preferences to predict an equilibrium matching of scientists to careers and to their earnings evolution. Our empirical analysis, using the National Science Foundation's Scientists and Engineers Statistical Data System database, is consistent with theoretical predictions of i sorting by ability into basic versus applied science among academic scientists, but not among industry scientists; and ii sorting by higher taste for nonmonetary returns into academia over industry. The evolution of an earnings profile is consistent with these sorting patterns: the earnings trajectories of basic and applied scientists are distinct from each other in academia but are similar in industry. This paper was accepted by Lee Fleming, entrepreneurship and innovation.
Severe hypoglycemia during intensive insulin therapy

Background: Tight glycemic control reduces mortality in surgical intensive care patients and in long‐term medical intensive care patients. A large study on intensive insulin therapy was prematurely discontinued due to safety issues. As the safety of intensive insulin therapy has been questioned, we screened all patients during a 17‐month period to reveal the incidence of hypoglycemia and its effects on the outcome of the patients.
Restenosis after coronary stent placement and randomization to a 4-week combined antiplatelet or anticoagulant therapy: six-month angiographic follow-up of the Intracoronary Stenting and Antithrombotic Regimen (ISAR) Trial.

BACKGROUND Platelets and mural thrombus at the lesion site may play a key role in initiating the restenosis process after coronary interventions. The ISAR Trial provides a comparison of the outcomes of patients randomized to two different antithrombotic regimens administered for 4 weeks after successful coronary stent placement: combined antiplatelet therapy (aspirin plus ticlopidine) or a conventional anticoagulant regimen (phenprocoumon with initial overlapping heparin plus aspirin). Within the first 4 weeks after stent placement, combined antiplatelet therapy has been associated with a significant reduction of ischemic complications. In the present study, we examined whether combined antiplatelet therapy administered for 4 weeks after stent placement is able to reduce the process of restenosis at 6 months. METHODS AND RESULTS Of 517 patients initially randomized, 496 were eligible for 6-month angiographic follow-up. Scheduled angiography was performed in 432 of the eligible patients (87.1%), 216 in each group. In a comparison of the two groups, there were no significant differences in clinical and procedural variables or in qualitative and quantitative lesion characteristics before and after stenting. At 6 months, minimal luminal diameter was 1.95+/-0.86 mm in the group with initial combined antiplatelet therapy and 1.90+/-0.87 mm in the group with initial anticoagulant therapy (P=.55). Late lumen loss was 1.10+/-0.81 and 1.15+/-0.75 mm (P=.54), and the restenosis rate was 26.8% and 28.9%, respectively (P=.70). Target lesion revascularization rate was 14.6% in the antiplatelet therapy group and 15.6% in the anticoagulant therapy group (P=.85). CONCLUSIONS This study shows that combined antiplatelet therapy (aspirin plus ticlopidine) administered for 4 weeks after coronary Palmaz-Schatz stent placement does not result in a detectable benefit for the prevention of restenosis compared with conventional anticoagulant therapy (phenprocoumon with initial overlapping heparin plus aspirin).
A comparative clinico-radiographic study of guided tissue regeneration with bioresorbable membrane and a composite synthetic bone graft for the treatment of periodontal osseous defects

Aim: The aim was to evaluate the bonefill in periodontal osseous defects with the help of guided tissue regeneration, bioresorbable membrane (PerioCol) + bone graft (Grabio Glascera) in combination and with bonegraft (Grabio Glascera) alone. Materials and Methods: The study involved total 30 sites in systemically healthy 19 patients. The parameters for evaluation includes plaque index sulcus bleeding index with one or more periodontal osseous defects having (i) probing depth (PD) of ≥ 5 mm (ii) clinical attachment loss (CAL) of ≥ 5 mm and (iii) ≥3 mm of radiographic periodontal osseous defect (iv) bonefill (v) crestal bone loss (vi) defect resolution. The study involved the three wall and two wall defects which should be either located interproximally or involving the furcation area. The statistical analysis was done using Statistical Package for Social Sciences, the Wilcoxon signed rank statistic W + for Mann-Whitney U-test. Results: The net gain in PD and CAL after 6 months for Group I ([PerioCol] + [Grabio Glascera]) and Group II (Grabio Glascera) was 3.94 ± 1.81 mm, 3.57 ± 2.21 mm and 3.94 ± 1.81, 3.57 ± 2.21 mm, respectively. The results of the study for Group I and Group II with regards to mean net bonefill, was 3.25 ± 2.32 (58%) mm and 5.14 ± 3.84 (40.26 ± 19.14%) mm, crestal bone loss − 0.25 ± 0.68 mm and − 0.79 ± 1.19 mm. Defect resolution 3.50 ± 2.34 mm and 5.93 ± 4.01 mm, respectively. Conclusion: On comparing both the groups together after 6 months of therapy, the results were equally effective for combination of graft and membrane versus bone graft alone since no statistical significant difference was seen between above parameters for both the groups. Thus, both the treatment modalities are comparable and equally effective.
5-Aza-2′-deoxycytidine protects against emphysema in mice via suppressing p16Ink4a expression in lung tissue

Background There is a growing realization that COPD, or at least emphysema, involves several processes presenting in aging and cellular senescence. Endothelial progenitor cells (EPCs) contribute to neovascularization and play an important role in the development of COPD. The gene for p16Ink4a is a major dominant senescence one. The aim of the present study was to observe changes in lung function, histomorphology of lung tissue, and expression of p16Ink4a in lung tissue and bone marrow-derived EPCs in emphysematous mice induced by cigarette-smoke extract (CSE), and further to search for a potential candidate agent protecting against emphysema induced by CSE. Materials and methods An animal emphysema model was induced by intraperitoneal injection of CSE. 5-Aza-2′-deoxycytidine (5-Aza-CdR) was administered to the emphysematous mice. Lung function and histomorphology of lung tissue were measured. The p16Ink4a protein and mRNA in EPCs and lung tissues were detected using Western blotting and quantitative reverse-transcription polymerase chain reaction, respectively. Results CSE induced emphysema with increased p16Ink4a expression in lung tissue and bone marrow-derived EPCs. 5-Aza-CdR partly protected against emphysema, especially in the lung-morphology profile, and partly protest against the overexpression of p16Ink4a in EPCs and lung tissue induced by CSE. Conclusion 5-Aza-CdR partly protected against emphysema in mice via suppressing p16Ink4a expression in EPCs and lung tissue.
Pronounced differences in signal processing and synaptic plasticity between piriform‐hippocampal network stages: a prominent role for adenosine

Extended trains of theta rhythm afferent activity lead to a biphasic response facilitation in field CA1 but not in the lateral perforant path input to the dentate gyrus. Processes that reverse long‐term potentiation in field CA1 are not operative in the lateral perforant path: multiple lines of evidence indicate that this reflects differences in adenosine signalling. Adenosine A1 receptors modulate baseline synaptic transmission in the lateral olfactory tract but not the associational afferents of the piriform cortex. Levels of ecto‐5’‐nucleotidase (CD73), an enzyme that converts extracellular ATP into adenosine, are markedly different between regions and correlate with adenosine signalling and the efficacy of theta pulse stimulation in reversing long‐term potentiation. Variations in transmitter mobilization, CD73 levels, and afferent divergence result in multivariate differences in signal processing through nodes in the cortico‐hippocampal network.
Distributed optimal fusion steady-state Kalman filter for systems with coloured measurement noises

Based on the optimal fusion criterion weighted by matrices in the linear minimum variance sense, an optimal information fusion steady-state Kalman filter is given for the discrete time-invariant linear stochastic control system measured by multiple sensors with coloured measurement noises, which is equivalent to an optimal information fusion steady-state Kalman predictor with a two-layer fusion structure for system with correlated noises. Furthermore, the steady-state optimal fusion predictor can be obtained only by fusing once after all local subsystems enter the steady-state predictions. The solution of steady-state prediction error cross-covariance matrix between any two subsystems can be obtained by iteration with an arbitratry initial value, whose convergence is proved. Applying it to a tracking system with three sensors shows its effectiveness.
Parental rearing patterns and suicidal thoughts

ABSTRACT– In an attempt to investigate the parental rearing patterns associated with presence of suicidal thoughts, a measure of child rearing patterns (EMBU) and the EPQ measure of personality dimensions were administered to 85 university students, 72 medical and surgical patients, and 125 employees of a state department, along with two questions tapping suicidal thoughts. Results indicated that those with suicidal ideation had parents who had separated more often than controls, and that parental rearing of those with suicidal thoughts included parents who favoured siblings rather than subject, were unstimulating, guilt‐engendering, rejecting and unaffectionate. Fathers were more abusive and punitive. These findings suggest that suicidal thoughts may be related to rejection and lack of self‐esteem, and that therapy which focuses on resolving parental rejection may be of some use in patients with suicidal ideation.
Production of voiced ingressive pl An analysis

The production of plosive consonants with an ingressive airstream is an often-encountered speech characteristic of deaf individuals. The present research examined the production of ingressive plosives employing an analysis-by-synthesis strategy. Production of ingressive plosive patterns appears related to specific alterations in synthesizer control parameters: supralaryngeal vocal-tract volume, glottal aperature, and occlusion duration. It is hypothesized that production of ingressives by deaf speakers in this study resulted from laryngeal lowering to increase vocal-tract volume, glottal closure during the occlusion interval, and extended occlusion duration.
Tourist Viewshed Externalities and Wind Energy Production

This study uses an experiment where ferry passengers are sold hotel room “views” to evaluate the impact of wind turbines views on tourists’ vacation experience. Participants purchase a chance for a weekend hotel stay. Information about the hotel rooms was limited to the quality of the hotel and its distance from a large wind turbine, as well as whether or not a particular room would have a view of the turbine. While there was generally a negative effect of turbine views, this did not hold across all participants, and did not seem to be effected by distance or hotel quality.
Teacher proposes, student disposes.

Malott proposes a problem in behavioral-science training and an attractive solution. The problem is that we need many practitioners and few researchers; the solution is to teach very many of the very many people who want to be practitioners to be practitioners, and teach the very few people who want to be researchers to be researchers. This problem is urgent only for those audiences who have not noticed that its solution is already a widespread reality: That is what we are doing right now and have been doing for some time. We simply have not been admitting that we do, as if that solution to the problem had no social validity. In fact, it is socially invalid only within a very small community, but this community is one of our most vocal and often gets taken as Our opinion. Thus Malott's argument is functional and valuable. Unfortunately, it is also more elegant than the issue requires. Malott devotes some interestingly conceptualized effort to empirical proof of his facts, but in my opinion not convincingly. For example, if we want to know what proportions of the world's probable 5,000 behavior analysts are researchers, practitioners, teachers, and administrators, we ought not to sample the 2,000 members ofABA, because, as Malott notes, ABA probably attracts, supports, and maintains membership from these categories differentially. Then why proceed with an ABAbased market analysis? The only fact wanted is that very many of our students after graduation fill roles other than researcher or research teacher. I recommend simply asserting that fact; it is so obvious to us that it needs no survey, and its credibility may even be damaged by an obviously inaccurate one. Similarly, if we want to know how many of the people we thought we had taught to publish
