Improving the Energy Efficiency by Cooperative Transmission in Multi-Hop Wireless Ad-Hoc Networks

Cooperative transmission has been recently proposed as a promising technique to combat multi-path fading and increased link reliability. It represents a potential candidate to exploit the benefits of using multiple antennas system without requiring to implement multiple antennas per terminal. There has been extensive research investigating physical layer issues of such systems; however, higher layer protocols that exploit cooperative links in ad hoc networks are still emerging in cooperative ad hoc networks, and it is important to effectively use cooperation without affecting the performance of the network. In this dissertation, we proposed a novel a characterization of the optimal multi-hop cooperative routing in ad hoc networks, and developed a metric for both evaluation. The key advantages of cooperative links are to minimize the number of hops while maintaining the QoS requirements and to minimize the end-to-end total power for a given rate. Also we showed that energy can be used more efficiently if we determine the joint optimal packet size and the optimal power allocation for both the source and the relay. For multi-flow scenario, we have proposed a clique-based inter-flow interference abstraction, and used the linear programming formulation to study the capacity gain of ad-hoc cooperative network. It is observed that the network capacity in multi-hop multi-flow settings is severely affected by interference between links and this effect increases when the cooperative relaying is imposed.
Demo-Testing Facility of Gamma-Activation Analysis for Gold Ores

We present the metrological characteristics and technical features of a gamma-activation analysis (GAA) method at a demo-testing facility, where methods for determining the concentrations of noble metals and other elements in rocks, ores, and their technological processing products are developed. Applying this installation, we can analyses samples from various mineral resources under various simulation conditions and optimize the measurement conditions of their samples. Such laboratory tests will provide clients with the real limits of detection of the elements being determined and the accuracy of their determination well in advance of their investment in their own GAA installations.

Does Civil Law Tradition and Universal Banking Crowd out Securities Markets? Pre-World War I Germany as Counter-Example

This article poses three main questions: Does the civil-law tradition favor large, concentrated, universal banking systems? Does this sort of legal system work against the development of active securities markets? Do powerful universal banks (whether or not legal tradition lies at the root of bank power) replace securities markets or prevent them from operating efficiently? Based on evidence from Pre-World War I Germany, this paper argues that the answer to all three questions is “no.”
Transcriptomic and metabolomic analysis provides insights into anthocyanin and pyocyanin accumulation in pear

BackgroundPear is one of the most important fruit crops worldwide. Anthocyanins and procyanidins (PAs) are important secondary metabolic substances that affect the appearance and nutritive quality of pear. However, few studies have focused on the molecular mechanism underlying anthocyanin and PA accumulation in pear.ResultsWe conducted metabolome and transcriptome analyses to identify candidate genes involved in anthocyanin and PA accumulation in young pear fruits of ‘Clapp Favorite’ (CF) and its red mutation variety ‘Red Clapp Favorite’ (RCF). Gene–metabolite correlation analyses revealed a core set of 20 genes for pear anthocyanin and PA accumulation. One gene in the core set, PcGSTF12, was confirmed to be involved in anthocyanin and PA accumulation by complementation of the tt19-7 Arabidopsis mutant. Interestingly, PcGSTF12 was found to be responsible for procyanidin A3 accumulation, but not petunidin 3, 5-diglucoside accumulation, opposite to the function of AtGSTs in Arabidopsis. Transformation with PcGSTF12 greatly promoted or repressed genes involved in anthocyanin and PA biosynthesis, regulation, and transport. Electrophoretic mobility shift and luciferase reporter assays confirmed positive regulation of PcGSTF12 by PcMYB114.ConclusionThese findings identify a core set of genes for pear anthocyanin and PA accumulation. Of these, PcGSTF12, was confirmed to be involved in anthocyanin and PA accumulation. Furthermore, an important anthocyanin and PA regulation node was constructed by two core genes, PcGSTF12 and PcMYB114. These results provide novel insights into anthocyanin and PA accumulation in pear and represent a valuable data set to guide future functional studies and pear breeding.
STRESS DISTRIBUTION BENEATH PAVEMENTS OF DIFFERENT RIGIDITIES

FULL SCALE TESTS HAVE BEEN MADE OF SINGLE, DUAL AND DUAL-TANDEM STATIC TIRE LOADS ON FLEXIBLE PAVEMENTS IN ORDER TO DETERMINE THE ACTUAL STRESS DISTRIBUTION IN THE SUBGRADE AND TO EVALUATE THE RELATIVE LOAD SPREADING ABILITY OF DIFFERENT BASE COURSE MATERIALS NOW IN USE. A COMPARISON OF THE TEST RESULTS WITH STRESSES COMPUTED FOR A HOMOGENEOUS, ISOTROPIC SOIL BY THE BOUSSINESQ THEORY INDICATES THAT BASE COURSES THAT DO NOT POSSESS TENSILE STRENGTH HAVE LIMITED LOAD SPREADING ABILITY. HOWEVER, A SOIL-CEMENT BASE COURSE, HAVING SOME TENSILE STRENGTH, WAS MUCH MORE EFFECTIVE IN LOAD SPREADING. THE DISTRIBUTION PATTERN IN THIS CASE WAS SIMILAR TO THAT COMPUTED BY THE BURMISTER-THEORY OF MULTI- LAYERED SYSTEMS.

Femoral periosteal reaction in the mid-piece of the prosthesis: a potential predictor of hip prosthetic joint infection

[Background] Early diagnosis of HPJI is important. Periosteal reaction has been shown to diagnose osteomyelitis and bone tumours; however, research on artificial joint infections is not clear. The purpose of this study was to analyse the diagnostic possibility of FPR on X-ray films for HPJI. [Methods] From January 2017 to June 2019, 105 patients who underwent artificial hip joint revision surgery were retrospectively included in the single joint surgery centre. Based on the description by the MSIS in 2013 and exclusion of patients with bone tumour revisions, 66 patients were reviewed and divided into the PJI group and aseptic failure (AF) group. The clinical outcome and radiographic results were examined by two experienced joint surgeons independently on hip X-ray images in all cases. Sensitivity, specificity, PPV and NPV were calculated for FPR in HPJI, and the imaging results were compared with those of serology and bacterial culture. [Results] A total of 16 patients in the PJI group were positive for FPR with appearance in the mid-piece and distal part, while 6 patients in the AF group (43.3% vs 26.1%, p = 0.04) were positive for FPR. Only 1 patient in the AF group had a mid-piece FPR, and the rest were at the distal end. Separated measurements were unidimensional (Kappa value = 0.89). The process of FPR-positive patients in the PJI group was 13 ± 26.1 months, and it was 9.83 ± 8.2 months in the AF group, and the difference was not statistically significant (p = 0.67). There was no connection between the responsible pathogens and FPR in the PJI group. The sensitivity, specificity, PPV and NPV for FPR at any section were 43.2%, 79.3%, 72.7% and 52.7%, respectively. The mid-piece FPR improved by 43.2%, 96.5%, 94.1% and 57.1%, respectively. Combined with elevated serum CRP/ ESR, specificity and PPV could reach 100%. [Conclusion] Preoperative X-ray examinations revealed that the mid-piece FPR requires a high degree of suspicion of PJI. If patients have elevated serum CRP/ESR at the same time, joint puncture and other methods should be used to obtain culture results to confirm the diagnosis.
Numerical Evaluation of the Performance of the Sister–Shaped Single–Hole Schemes on Turbine Blade Leading Edge Film Cooling

In the present study, a numerical evaluation of the performance of the sister-shaped single-hole (SSSH) schemes (downstream, upstream and up/downstream) on the leading edge of AGTB-B1 high pressure turbine blade cascade is carried out. Simulations are performed at three blowing ratios of 0.7, 1.1 and 1.5. Predicted results are compared to the single cylindrical hole and a 15° forward-diffused shaped hole. The realizable k-e model combined with the standard wall function is used to model the flow field; wherein, the predicted pressure field was in a good agreement with the available experimental data. At the high blowing ratios of 1.1 and 1.5, a noticeable improvement in the film cooling effectiveness and the lateral spread of the cooling jet has been observed for the upstream and up/downstream SSSH schemes, in particular on the suction side. The downstream SSSH configuration provided almost similar film cooling effectiveness values to that of the forward diffused shaped hole for all blowing ratios on both the pressure and suction sides of the blade. Note that the obtained film cooling effectiveness for the downstream SSSH scheme at high blowing ratios was disappointing in comparison with other SSSH schemes where much higher film cooling effectiveness values were obtained. The mixing of the coolant with the high mainstream flow at the leading edge of the blade is considerably decreased for the upstream and up/downstream SSSH schemes and more adhered coolant to the blade’s surface is observed than with other configurations. Moreover, the jet lift-off is notably diminished for the upstream and up/downstream SSSH compared to other hole geometries.Copyright © 2015 by ASME
Hybrid Learning Control Schemes With Input Shaping Of A Flexible Manipulator System

Input shaping is a simple method for reducing the residual vibration in positioning lightly damped systems. Although several input shaping techniques have been derived to control a flexible manipulator system without payload, theoretical results are hard to be traced for their application to control a flexible manipulator system in real time. This project attempts to describe a practical approach to investigate and develop a hybrid iterative learning control scheme with input shaping. An experimental flexible manipulator rig and corresponding simulation environment are used to demonstrate the effectiveness of the proposed control strategy. In this work, a single link flexible robot manipulator that moves in horizontal plane is considered. A collocated proportional-integral-derivative (PID) controller utilizing hub-angle and hub-velocity feedback is developed for control of rigid-body motion of the system. This is then extended to control the system with acceleration feedback for optimization of the learning parameters and a feed forward controller based for nonlinear model closed loop system on input shaping technique for control of vibration (flexible motion) of the system. The system performance with the controllers is presented and analysed in simulation using MATLAB and SIMULINK. The performance of the PID controller with input shaping is assessed in terms of level of vibration reduction. The effectiveness of the control schemes in handling various speed of flexible link is also analyzed. The performance of the system in term of with and without input shaping method also been compared. From the simulation results, satisfactory vibration reduction of a flexible manipulator has been achieved using the proposed method.
PREDICTION AND CONTROL OF PEDESTRIAN-INDUCED VIBRATION IN FOOTBRIDGES

Footbridges vibrate because the forces imparted by the user are applied with the frequency of the pace and movement, however small, is therefore a forced vibration. In instances where the pace coincides with a structure resonant frequency dynamic movement can be quite large and the user may be disturbed or even alarmed. Vibration is recognized as a serviceability limit state and a process that can be employed as a design tool permitting an early assessment of behavior is proposed. The subject is investigated in terms of the pedestrian excitation source, the structure response, and acceptance criteria. Calculated response compares favorably with test results. Remedial or preventative options in the form of various damping devices are reviewed.
Mesenchymal stem cell surgery, rescue, and regeneration in glaucomatous optic neuropathy

Background Glaucomatous optic neuropathy (GON) is an anatomofunctional impairment of the optic nerve triggered by glaucoma. Recently, growth factors (GF) have been shown to produce retinal neuroenhancement. The suprachoroidal autograft of mesenchymal stem cells (MSC) by Limoli Retinal Restoration Technique (LRRT) has proven to achieve retinal neuroenhancement by producing GF directly into the choroidal space. This retrospectively registered clinical study investigated the visual function changes in patients with GON treated with LRRT. Methods: Twenty-five patients (35 eyes) with GON in progressive disease conditions were included in the study. Each patient underwent a comprehensive ocular examination, including analysis of Best Corrected Visual Acuity (BCVA) for far and near visus, sensitivity by Maia microperimetry, and the study of the spectral domain-optical coherence tomography (SD-OCT). The patients were divided into two groups: a control group, consisting of 21 eyes (average age 72.2 years, range 50–83) and an LRRT group, consisting of 14 eyes (average age 67.4, range 50–84). Results: After 6 months the BCVA, close-up visus, and microperimetric sensitivity significantly improved in the LRRT-treated group (p < 0.05), whereas the mean increases were not statistically significant in controls (p > 0.5). Conclusions: Patients with GON treated with LRRT showed a significant increase of visual performance (VP) both in BCVA and sensitivity and an improvement of residual close-up visus, in the comparison between the LRRT results and the control group. Further studies will be needed to establish the actual significance of the reported findings.
Surveying Student Perspectives of Quality: Value of QM Rubric Items

This survey builds on previous work started in 2007 at University of Wisconsin Extension (Nath & RalstonBerg, 2008; Ralston-Berg & Nath, 2008; Ralston-Berg & Nath, 2009). The Quality Matters (QM) program offers quality assurance through a research-based rubric for online course design. From an instructional design standpoint, questions arise about the student perspective. If the QM Rubric is based on academic research initiated most often by content experts or others in academia delivering online content, do online students – consumers of those courses – have a differing perspective on what makes a quality online course? Do students agree that items presented in the QM Rubric indicate quality? Are items in the QM Rubric perceived as contributors to student success?
Dress Syndrome

Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) is a rare, idiosyncratic, life-threatening drug reaction with a variety of clinical manifestations including symptoms of fever higher than 38.5 oC, pruritic maculopapular or erythematous eruption, hematologic abnormalities, lymphadenopathy, and multiorgan involvement. Its incidence ranges from 1 in 1000 to 1 in 10,000 drug exposures, and it has an estimated mortality rate of up to 10%. To date, many drugs have been reported to cause DRESS syndrome, but the most common ones are the anticonvulsants and sulfonamides, although the pathogenesis is not clearly understood. Deficiency or defects in the epoxide hydroxylase enzyme, which detoxifies the metabolites of aromatic anticonvulsants, an insufficiency in the detoxification of the drug leading to reactive metabolites which may trigger immunologic reactions, predispositions due to some HLA alleles, and reactivation of herpes viruses are suggested to play a role in the pathogenesis. The latent period varies from two to six weeks. Hematologic, hepatic, renal, cardiac, pulmonary, neurologic, gastrointestinal and endocrine involvement; and hemophagocytic syndrome can be seen during the clinical course of DRESS syndrome. The long term sequels of DRESS syndrome include hepatic, renal and adrenal failure; diabetes mellitus type 1 and type 2, Graves disease, autoimmune hemolytic anemia, lupus, systemic sclerosis, and autoimmune enteropathy. Diagnosis of DRESS syndrome is difficult to establish, and requires a high degree of initial clinical suspicion and ruling out of other etiologies. The most important step in the management of DRESS syndrome is early diagnosis and prompt withdrawal of the offending drug. In cases with organ involvement, systemic corticosteroid treatment is required. In serious and steroid-resistant cases, using more potent immunosuppressive agents or intravenous immunoglobulin treatments may be required.

Analysis of Injury Severity of Drivers Involved in Single-Vehicle and Two-Vehicle Crashes on Ontario Highways Using Heteroscedastic Ordered Logit Models

The objective of this study is to analyze driver’s injury severity in single-vehicle and two-vehicle crashes and compare the effects of explanatory variables between various types of crashes. The study identified factors affecting injury severity and their effects on severity levels using 5-year crash records for provincial highways in Ontario, Canada. Considering non-uniform variations in unobserved effects of explanatory variables on injury severity among observations called “heteroscedasticity”, heteroscedastic ordered logit (HOL) models were developed for single- vehicle and two-vehicle crashes separately. The results show that there exists heteroscedasticity for some variables in both single-vehicle and two-vehicle crash models. The results also show that some factors have opposite effects between single-vehicle and two-vehicle crashes, and between car-car crashes and truck-truck crashes. The study demonstrates that HOL models using separate crash data sets classified by vehicle type can better capture the associations of variables with driver’s injury severity.
Exchange rate volatility and Foreign Direct Investment in South Asia

This paper examines the effect of Real Exchange Rate Volatility (RERVOL) on the Foreign Direct Investment (FDI) inflow in Bangladesh, India, Pakistan and Sri Lanka. A model that includes exchange rate volatility with other determinants of FDI is developed. Annual time series data from 1976â€“2009 is used for India, Pakistan and Sri Lanka. In case of Bangladesh because of the data limitation only data series from 1986â€“2009 is used. A panel data from these four countries for a period of 1986â€“2009 is also constructed. Before estimating the model the time series properties of the data are diagnosed and an error correction model is developed. The estimated results show an inconclusive relationship between the exchange rate volatility and the FDI.
Predictive values of multiple serum biomarkers in women with suspected preeclampsia: a prospective study

Background: Preeclampsia is a common obstetric multisystem disorder causing maternal and fetal morbidity and mortality; it’s been shown that the prediction improves preeclampsia outcomes in pregnancy. However, the current serum biomarkers had low clinical application values and still lack validation studies. Here we aimed to evaluate the preeclampsia prediction values of a series of serum biomarkers in Chinese pregnant women of > 20 weeks of gestation. Methods: Singleton pregnant women with preeclampsia-related clinical and/or laboratory presentations were recruited and had blood drawn at their first visits. The prospective cohort was further divided into preeclampsia-positive and preeclampsia-negative groups based on the follow-up results. The following markers were tested using the collected serum samples: soluble fms-like tyrosine kinase-1 (sFlt-1); placental growth factor (PlGF); thrombomodulin (TM); tissue plasminogen activator inhibitor complex (tPAI-C); compliment factors C1q, B, and H; glycosylated fibronectin (GlyFn); pregnancy-associated plasma protein-A2 (PAPP-A2); blood urea nitrogen (BUN); creatinine (Cre); uric acid (UA); and cystatin C (Cysc). Results: A total of 196 women with suspected preeclampsia were recruited with follow-up medical records. Twenty-five percent (n=49) of the recruited subjects developed preeclampsia before delivery, and 75% remained preeclampsia-negative (n=147). The serum levels of sFlt-1, BUN, Cre, UA, Cysc and PAPP-A2 were significantly elevated, and the PlGF level was significantly decreased in the preeclampsia-positive patients. In the receiver operating characteristics (ROC) analyses, the area under the curves were listed in the order of decreasing values: 0.73 (UA), 0.67 (sFlt-1/PlGF), 0.66 (Cysc), 0.65 (GlyFn/PlGF), 0.64 (PAPP-A2/PlGF), 0.63 (BUN), 0.63 (Cre), and 0.60 (PAPP-A2). With the cut-off values obtained from the ROC analyses, the positive predictive values of these serum markers were between 33.1% and 58.5%, and the negative predictive values were between 80.9% and 89.5%. Conclusions: Although several serum markers were found to be significantly changed with current prospective cohort, their limited predictive values in preeclampsia development posed potential barrier in clinical implementation. Further studies with larger cohort are warranted to further reveal the clinical utilities of the serum markers in preeclampsia prediction.
