Motions obtaining of multi-degree-freedom underwater robot by using reinforcement learning algorithms

This paper deals with motions obtaining of an underwater robot arm which have multi-degree of freedom by using reinforcement learning algorithms. A natural gradient Actor-Critic algorithm which uses Eligibility Traces is applied to the robot arm. In this algorithm, motion planning problems are modeled as finite state Markov decision processes. The robot arm is developed to have 4 joints, each joint consists 1 servo motor. The experiment results show the robot arm successfully learning to swim by feasible learning steps.
A distributed power control algorithm in cognitive radio networks based on Nash bargaining solution

In the spectrum underlay model, cognitive radios can access the spectrum owned by primary users if they can limit their interference power below a certain threshold, called interference temperature limit (ITL). In this paper, we study the power control problem under ITL. By considering both efficiency and fairness, the power control problem is modeled as a cooperative game. A power control scheme based on Nash bargaining solution (NBS) is proposed. We present a distributed power control (DPC) algorithm based on NBS. The convergence of DPC algorithm is proven by theoretic analysis. Simulation results show that proposed DPC algorithm achieves an effective tradeoff between fairness and efficiency.
Taking Account of Societal Concerns About Risk: Framing the Problem

Risk is subjective. It is a word that refers to a future that exists only in the imagination. The Health and Safety Executive (HSE), as Britain's pre-eminent risk manager, has the challenging task of taking into account societal concerns about risk. The task is challenging, and often thankless, because society and its concerns are heterogeneous-" society " consists of diverse groups of stakeholders or social solidarities, and their concerns are commonly in conflict with each other. In this report we • = characterise risk management as a balancing act involving uncertain rewards and costs, • = describe the different groups with which the HSE must contend in performing its balancing act, • = note the significance of the different types of risk about which they are concerned, and • = conclude that attempts to manage risk that a) ignore the rewards of risk taking, and/or b) exclude significant stakeholders, and/or c) fail to appreciate the type of risk it is sought to manage, are unlikely to succeed. We have, we hope, brought a modicum of order to a large amount of chaos. This report and the work it describes were funded by the HSE.

Adaptor protein complex 2–mediated, clathrin‐dependent endocytosis, and related gene activities, are a prominent feature during maturation stage amelogenesis

Molecular events defining enamel matrix removal during amelogenesis are poorly understood. Early reports have suggested that adaptor proteins (AP) participate in ameloblast‐mediated endocytosis. Enamel formation involves the secretory and maturation stages, with an increase in resorptive function during the latter. Here, using real‐time PCR, we show that the expression of clathrin and adaptor protein subunits are upregulated in maturation stage rodent enamel organ cells. AP complex 2 (AP‐2) is the most upregulated of the four distinct adaptor protein complexes. Immunolocalization confirms the presence of AP‐2 and clathrin in ameloblasts, with strongest reactivity at the apical pole. These data suggest that the resorptive functions of enamel cells involve AP‐2 mediated, clathrin‐dependent endocytosis, thus implying the likelihood of specific membrane‐bound receptor(s) of enamel matrix protein debris. The mRNA expression of other endocytosis‐related gene products is also upregulated during maturation including: lysosomal‐associated membrane protein 1 (Lamp1); cluster of differentiation 63 and 68 (Cd63 and Cd68); ATPase, H+ transporting, lysosomal V0 subunit D2 (Atp6v0d2); ATPase, H+ transporting, lysosomal V1 subunit B2 (Atp6v1b2); chloride channel, voltage‐sensitive 7 (Clcn7); and cathepsin K (Ctsk). Immunohistologic data confirms the expression of a number of these proteins in maturation stage ameloblasts. The enamel of Cd63‐null mice was also examined. Despite increased mRNA and protein expression in the enamel organ during maturation, the enamel of Cd63‐null mice appeared normal. This may suggest inherent functional redundancies between Cd63 and related gene products, such as Lamp1 and Cd68. Ameloblast‐like LS8 cells treated with the enamel matrix protein complex Emdogain showed upregulation of AP‐2 and clathrin subunits, further supporting the existence of a membrane‐bound receptor‐regulated pathway for the endocytosis of enamel matrix proteins. These data together define an endocytotic pathway likely used by ameloblasts to remove the enamel matrix during enamel maturation. © 2013 American Society for Bone and Mineral Research.
Preliminary HPLC study on some polyphenols of Geranium robertianum L. (Geraniaceae).

In order to continue our previous studies concerning Geranium robertianum L. , herb Robert (Geraniaceae), we have realised a HPLC study of some polyphenols using an original method created by a group of young researchers from the University of Medicine and Pharmacy of Cluj-Napoca. We have identified and measured in the dried Geranii robertiani herba (harvested from Valea Runcului, district of Alba-Iulia) the following compounds: hyperoside (3.64 microg/100 mg), ellagic acid (7599.76 microg/100 mg), isoquercitrin (49.49 microg/100 mg), quercetrin (83.92 microg/100 mg), kaempferols (143.43 microg/100 mg), caftaric acid (166.92 microg/100 mg), rutoside (72.23 microg/100 mg). We have also analysed a hydrolysed sample of the same drug in which we have identified and measured: caffeic acid (6.62 microg/100 mg), ellagic acid (10550.65 microg/100 mg), quercetrin (203.44 microg/100 mg), kaempferols (231.80 microg/100 mg), caftaric acid (47.41 microg/100 mg). We have indirectly proved the presence of ellagic tannins (the amount of ellagic acid increases after acid hydrolise) and the existence of bi- or polycaffeoil derivatives (the caffeic acid is present only in the hydrolysed sample). The flavonoid aglycones exist in both forms: as free compounds and as part of the flavonoid molecules.
Tunable hairpin resonator based on liquid crystal

A novel tunable resonator with using liquid crystal as a dielectric is proposed. Due to the bias-dependent permittivity of an anisotropic nematic liquid crystal embedded in the resonator's multilayer substrate, a differential phase shift of 180° in the reflection coefficient is predicted in X band. The resonator was fabricated and the measured characteristics agree very well with the simulated data.
Wideband Millimeter-Wave Antennas With Magnetic-Dipole Patterns Integrated in Metallic Structures

Two realizations of millimeter-wave (mm-wave) antennas with wideband and broad beam characteristics are introduced for flush integration in metallic structures. The antenna design exploits the half-mode substrate-integrated waveguide structure and its characteristic radiation loss close to cutoff. The target bandwidth extends from 30 to 40 GHz. The proposed antennas are analyzed and optimized using a highly efficient and accurate semianalytical solution with dedicated considerations of the losses in mm-wave band as well as optimization with emphasis on the radiation pattern quality. The transition is carefully designed for structure integration and for reduction of discontinuity-induced ripples in the radiation patterns over the wideband operation. Good agreement between the analysis, simulation, and measurement results validates the theoretical approach of the designs. The unique characteristics make the proposed antennas excellent candidates for future wireless communication systems requiring broad beam and horizontal polarization.
Ampe Akelyernemane Meke Mekarle "Little children are sacred": Report of the NT Board of Inquiry into the protection of Aboriginal children from sexual abuse

The Board of Inquiry was created by the Northern Territory Government in August 2006 to research and report on allegations of sexual abuse of Aboriginal children. The Inquiry was established to find better ways to protect Aboriginal children from sexual abuse. The Inquiry gathered and reviewed a vast amount of information that was shaped into 97 recommendations for the Chief Minister. Underlying the Inquiry’s findings was the common view that sexual abuse of Aboriginal children is happening largely because of the breakdown of Aboriginal culture and society. Important points made by the Inquiry included: Child sexual abuse is serious, widespread and often unreported. Most Aboriginal people are willing and committed to solving problems and helping their children. They are also eager to better educate themselves. Aboriginal people are not the only victims and not the only perpetrators of sexual abuse. Much of the violence and sexual abuse occurring in Territory communities is a reflection of past, current and continuing social problems which have developed over many decades. The combined effects of poor health, alcohol and drug abuse, unemployment, gambling, pornography, poor education and housing, and a general loss of identity and control have contributed to violence and to sexual abuse in many forms. Existing government programs to help Aboriginal people break the cycle of poverty and violence need to work better. There is not enough coordination and communication between government departments and agencies, and this is causing a breakdown in services and poor crisis intervention. Improvements in health and social services are desperately needed. Programs need to have enough funds and resources and be a long-term commitment.
ENHANCED PHOSPHORUS REMOVAL BY GLUCOSE FED SEQUENCING BATCH REACTOR

In this study an anaerobic/aerobic sequencing batch reactor was used for an enhanced biological phosphorus removal. These conditions were tested by a laboratory scale reactor (14 liter) with a synthetic feed, glucose being the sole carbon source. However, enhanced biological phosphorus removal (EBPR) was not achieved during this study. A series of batch tests were conducted with various substrates; acetic acid, glucose and the mixture of acetic acid and glucose. High phosphate removal was obtained when acetate was the substrate (68.7%). It was observed that when the acetic acid was used as a sole substrate, the bacteria growing in the alternating anaerobic/aerobic system removed the organic substrate under anaerobic conditions. However, in case of the glucose feed most of the COD removal took place under not truly anaerobic conditions. This also coincides with low phosphate removal (37.8%). These results are in consistent with the results of the continuous operation. When the acetic acid–glucose mixture was used, the phosphate removal decreased down to 60.8%. This was thought to be due to the glucose that reduced the dependency on poly-P as an energy source.
Visitors’ place-based evaluations of unacceptable tourism impacts in Oulanka National Park, Finland

ABSTRACT Visitors’ assessments of the negative impact of tourism, on physical and social environment, vary based on the location where the evaluation occurs. Research that focuses on identifying visitors’ norms within outdoor recreation settings has not been able to link the geographical location with the corresponding evaluation of unacceptable levels of impact. This study combines a traditional on-site visitor survey with a Public Participation Geographic Information Systems survey to produce spatially explicit information on visitors’ acceptance of tourism impacts. Using a web-based participatory survey, visitors were asked to indicate specific locations where they felt the effects of tourism disturbed the quality of their experience in Oulanka National Park. These evaluations were analyzed at multiple scales – destination, specific zones, and sites – to promote more efficient park management. Based on visitor evaluations, we found a collection of hotspots in the park where tourism has already caused unacceptable impacts. Visitors noted that crowding and erosion disturbed their experiences, especially along highly visited trail sections, while littering was considered problematic near wilderness huts. However, participant satisfaction at these sites was not lower than elsewhere in the park. This indicates that the association between negative impacts of tourism and visitor satisfaction is not straightforward, but complex. This study encourages the collection of spatially accurate data on visitors’ assessments of the effects of tourism because it has the potential to more efficiently direct park management policies. In addition, spatial techniques provide a new means to monitor the impacts of tourism, acknowledging that visitors’ perceptions of acceptability of tourism impacts also vary within tourism destinations, such as parks.
Effect of reduced dietary protein intake on hepatic and plasma essential fatty acid concentrations in the adult female rat: effect of pregnancy and consequences for accumulation of arachidonic and docosahexaenoic acids in fetal liver and brain*

During pregnancy, the accumulation of long-chain polyunsaturated fatty acids (LCPUFA) in fetal tissues places a substantial demand upon maternal lipid metabolism. As lipid metabolism is intimately linked to aspects of protein metabolism, a reduced protein intake in pregnancy may impair activities of enzymes and transport proteins responsible for supplying LCPUFA to the fetus, thereby compromising fetal development. We have investigated the effect of reduced protein intake on LCPUFA status in the non-pregnant rat and in the pregnant rat, and in fetus at day 20 of gestation. Female rats (n 5 per group) were either mated and fed the control diet (180 g protein/kg) or low-protein diet (90 g protein/kg, LPD) diet throughout pregnancy, or fed the control diet or LPD for 20 d (non-pregnant animals). The fatty acid compositions of maternal liver and plasma, and fetal liver and brain were determined by GC. Feeding the LPD did not lead to any gross changes either in adult or fetal growth, or in total lipid concentrations in adult rat liver. However, the LPD was associated specifically with lower liver (42·6 %) and plasma (19·4 %) phosphatidylcholine (PC), and plasma triacylglycerol (28·6 %) docosahexaenoic acid (DHA) concentrations in pregnant rats and reduced fetal brain PC- (26·1 %) and phosphatidylethanolamine- (25·6 %) DHA concentrations. Together, these results show that variations in maternal dietary protein consumption alter DHA status in pregnancy and modify DHA accumulation into the fetal brain. The present results suggest that lower maternal protein intakes reduce delivery of DHA from the mother to the fetus, which may impair development and function of the fetal brain.
Correlation between TCM Subjective Symptoms and Biomedical Parameters in 500 Hypertension Patients with Biostatistics Approach

In order to classify the TCM subjective symptoms of hypertension and explore the relationship between TCM symptoms and body weight, waist circumference, course of disease and blood fat, factor analysis, spearman analysis and T test were used to analyze the clinical data from 500 primary hypertension patients. The results showed that the different TCM symptom groups were related to different biomedical signs. The results suggest that it is reasonable to further classify the hypertension with TCM symptoms and make different therapies with further stratification of hypertension patients.

NDM-5 Carbapenemase-Encoding Gene in Multidrug-Resistant Clinical Isolates of Escherichia coli from Algeria

ABSTRACT Here, we report the first autochthonous cases of infections caused by blaNDM-5 New Delhi metallo-β-lactamase-producing Escherichia coli strains recovered from urine and blood specimens of three patients from Algeria between January 2012 and February 2013. The three isolates belong to sequence type 2659 and they coexpress blaCTX-M-15 with the blaTEM-1 and blaaadA2 genes.
Genetic Organization of Plasmid ColJs, Encoding Colicin Js Activity, Immunity, and Release Genes

ABSTRACT The 5.2-kb ColJs plasmid of a colicinogenic strain ofShigella sonnei (colicin type 7) was isolated and sequenced. pColJs was partly homologous to pColE1 and to pesticin-encoding plasmid pPCP1, mainly in the rep,mob, and cer regions. A 1.2-kb unique region of pColJs showed significantly different G+C content (34%) compared to the rest of pColJs (53%). Within the unique region, seven open reading frames (ORFs) were identified. ORF94 was shown to code for colicin Js activity (cja), a 94-amino-acid polypeptide (molecular mass, 10.4 kDa); ORF129 (cji) was shown to code for the 129-amino-acid colicin Js immunity protein (molecular mass, 14.3 kDa); and ORF65 was shown to be involved in colicin Js release by producer bacteria (cjl) coding for a 65-amino-acid polypeptide (molecular mass, 7.5 kDa). In contrast to the gene order in other colicin operons, the cjl gene was found upstream from cja. Moreover, the promoter upstream from cjl was similar to promoters described upstream from several colicin activity genes. The cji gene was found to be located downstream from cja with a transcription polarity opposite to that of the cjl andcja genes. The cja, cji, and cjl genes were not similar to other known colicin genes. Colicin Js was purified as an inactive fusion protein with an N-terminal histidine tag. Activity of the purified fusion form of colicin Js was restored after cleavage of the amino acids fused to the colicin Js N terminus.
Mobile X-ray service for nursing homes.

BACKGROUND Transport to a radiology department can be a strain on nursing home patients, leading to less use of diagnostic imaging. The purpose of this study was to examine the use and benefit of a mobile X-ray service that enables imaging at nursing homes. MATERIAL AND METHOD In connection with 300 of a total of 326 referrals to a mobile X-ray service in Vestfold County in the period March to September 2015, 66 doctors at 33 nursing homes completed a questionnaire on the options patients would have had in the absence of the mobile service. A hundred of these referrals were followed up one to two weeks later with a further questionnaire on the implications of the X-ray scan for diagnosis, treatment and nursing. Eighty-seven questionnaires were completed. RESULTS In 219 cases (73 %), the patients would have been sent to a hospital radiology department if the mobile X-ray service had not been available. In 60 cases (20 %) the patients would not have had an X-ray examination. In the follow-up, doctors answered that the X-rays had yielded new diagnostic information in 81 cases (95 %), that 71 (83 %) of the X-ray results had had implications for further treatment and that 29 (34 %) had helped patients avoid hospitalisation. In 77 cases (89 %), the X-rays enabled important information to be given to patients and their families. CONCLUSION A mobile X-ray service makes it possible to avoid transports that place a strain on patients and to provide necessary diagnoses for patients who would not otherwise have been examined.
Estimation of the power spectral density in nonstationary cardiovascular time series: assessing the role of the time-frequency representations (TFR)

Spectral analysis of cardiovascular series has been proposed as a noninvasive tool for investigating the autonomic control of the cardiovascular system. The analysis of such series during autonomic tests requires high resolution estimators that are capable to track the transients of the tests. A comparative evaluation has been made among classical (FFT based), autoregressive (both block and sequential mode) and time-frequency representation (TFR) based power spectral estimators. The evaluation has been performed on artificial data that have typical patterns of the nonstationary series. The results documented the superiority of the TFR approach when a sharp time resolution is required. Moreover, the test on a RR-like series has shown that the smoothing operation is effective for rejecting TFR crossterms when a simple, two-three components series is concerned. Finally, the preliminary application of the selected methods to real RR interval time series obtained during some autonomic tests has shown that the TFR are capable to correctly represent the transient of the series in the joint time-frequency domain.
Re-Evaluating the Political Press : A Case Study on Political, Economic and Journalistic Functioning of the Inter-War Czechoslovak Party-press Newspaper Národní listy, and its Publishing Company the Prague Stock Printery (PAT)

This article attempts to re-assess the often negative evaluations of the political press, through a detailed analysis of a case study from inter-war Czechoslovakia, the newspaper Narodni listy, and its publishing company the Prague Stock Printery (PAT), which were affiliated to the National Democratic Party. The analysis is theoretically framed by a discussion of notions of party-press parallelism and political parallelism, and how these political models are evaluated within the contemporary literature. In the following parts, an extensive (but necessary) contextualization is offered, which first focuses on the political-economic history of inter-war Czechoslovakia, and a description of its media landscape, and then details the workings of PAT and Narodni listy. The analytical parts first describe the financial, managerial and editorial situation of PAT and Narodni listy, and then evaluates their functioning at the economic, political and journalistic level. This evaluation shows the complexities of the political model from within the actual publishing practice, and demonstrates both the advantages and problems of the political model, compensating for the frequent exclusively negative evaluations of this model.
Brachyspina Syndrome in a Holstein Calf

A stillborn premature Holstein calf was necropsied. The calf had severely reduced body weight and shortening of the vertebral column. The limbs appeared long and thin. Radiography and computer tomography scanning were performed, demonstrating malformation of the vertebral column. In addition, malformation of the kidneys, testicles, and heart was found at necropsy. Histologically, absence or incomplete development of intervertebral discs and complete or partial fusion of the epiphyses of adjacent vertebrae were found. In some areas, diaphyses of adjacent vertebrae were fused due to absence of epiphyses and intervertebral discs. Disturbed ossification of epiphyses in the appendicular skeleton was also present. The etiology of this syndrome was not identified. An inherited cause is possible due to a close relationship between the parents.
