A chorus song style influences sexual responses in female canaries

We examined whether the playback of a chorus song style (i.e., two songs presented simultaneously from a single speaker) influences sexual song preferences of female domesticated canaries, Serinus canaria. Six females were treated with estradiol and their responses to the different types of song were measured as the frequency of copulation solicitation displays. Females responded preferentially to a chorus song style and reacted less to presentation of single songs (conspecific and heterospecific). These observations suggest that females sexual responses are elicited by two songs heard simultaneously. Our results are discussed in relation to current views on the song preferences of females and the phenomenon of chorus singing in songbirds.
Pyrrolnitrin from Myxococcus fulvus (Myxobacterales).

In a screening Program for antibiotics from gliding bacteria, we found that culture supernatants of Myxococcus fulvus strain Mx f147 strongly inhibited the growth of the mold, Mucor hiemais . This activity could be resolved into two compounds which proved identical with pyrrolnitrin(1)and aminopyrrolnitrin(2). Pyrrolnitrin was originally described in 1964 fromPseudomonas pyrrocinia 1,2,8) , while aminopyrrolnitrin was discovered in 1968 in cultures of.P. auerofaciens and is regarded as the immediate biosynthetic precursor of pyrrolnitrin3). Both antibiotics are also known from several other
Epibisdehydroneotuberostemonine J

The title compound, C22H29NO4, a stemona alkaloid, is composed of two lactone rings (A and E), a six-membered ring (B), a pyrrole ring (C) and a seven-membered ring (D). The five-membered rings A and E exhibit envelope conformations (C atoms as flaps) while ring C is planar. Ring B exhibits a twist-chair conformation due to fusion with pyrrole ring C while ring D adopts a chair conformation. The junction between rings A and B is cis. In the crystal, weak C—H⋯O interactions involving the two carbonyl groups, a methylene and a methyl group give rise to a three-dimensional network.
Co-integration of filters and waveguide to microstrip transitions using the foam technology

In this paper, we discuss about original designs of passive structures integrated within a common housing foam material. Milling and pressed moulding techniques are used to produce particular shapes (ridge, cavities,.) then allowing a complete integration and simultaneous association of passive functions (filter, waveguide, microstrip line, polariser.). The foam material is considered either as a supporting structure or as a grooved cavity with internal elements. Experimental as well as simulated results are presented, with original association of volumic and planar functions.
Susceptibility to five antimicrobial agents of strains of the Bacteroides fragilis group isolated in Brazil

The in vitro activity of metronidazole, chloramphenicol, clindamycin, cefoxitin, and carbenicillin was tested by an agar dilution method against 228 strains of the Bacteroides fragilis group isolated from human intestinal microbiota during 1981 and 1982. All the strains were susceptible to metronidazole. Resistance rates for chloramphenicol, clindamycin, cefoxitin, and carbenicillin were 2, 37, 21, and 13%, respectively.
Family tension in the search for a kidney donor.

The search for a kidney transplant donor is a significant decision-making stress for many extended families. The family is asked to donate the kidney of one member to save the life of another. Seventy-nine cases were reviewed and family tension is noted in 21 of these. It is concluded that earlier studies have minimized the nature of this crisis, because they have not focused on the family as an interacting unit or on the nondonor—the family member who "could" donate but does not.
Endotracheal tube sizes for children

Slater and his colleagues’ produced a table showing the endotracheal tube size most likely to be correct for each age group of children after a survey of 3956 patients. They found, however, that it was not possible to predict the correct tube size with any great confidence. One of the reasons for this was thought to be the differences in size between children of the same age but, although weight measurement was suggested as a possible indicator of tube size, they did not investigate the matter further. An attempt has been made in the study reported below to compare the reliability of age, weight and height measurements as indicators of the correct size endotracheal tube.

The Influence of World Factors on Finnish Stock Market Volatility

This paper investigates to what extent the volatility of Finnish stock portfolios is transmitted through the “world volatility”. We operationalize the volatility processes of Finnish leverage, industry, and size portfolio returns by asymmetric GARCH specifications according to Glosten et al. (1993). We use daily return data for January, 2, 1987 to December 30, 1998. We find that the world shock significantly enters the domestic models, and that the impact has increased over time. This applies also for the variance ratios, and the correlations to the world. The larger the firm, the larger is the world impact. The conditional variance is higher during recessions. The asymmetry parameter is surprisingly non-significant, and the leverage hypothesis cannot be verified. The return generating process of the domestic portfolio returns does usually not include the world information set, thus indicating that the returns are generated by a segmented conditional asset pricing model.
Managing Turnaround with Responsible Entrepreneurship: The Kedrion Case

In the present paper we argue that discipline and enthusiasm (or commitment) are two basic drivers of CSR within an organization. This distinction aims to capture “how” CSR is actually promoted and spread within an organization, while scholars seem to place greater attention on the “why”, that is the reasons for CSR. We explore this issue with the aim of Kedrion, an Italian, family – owned, medium – sized company, active in the hemoderivatives industry, that reacted to financial difficulties also by investing significant managerial resources to CSR and business ethics.The Kedrion case suggests that discipline and enthusiasm can play very important, even if different, roles in promoting and spreading CSR within a medium – sized company. In case of discipline, CSR has as primary function that of reducing a firm’s risk profile and saving reputation, focusing on formal rules and specific organizational structures, and tends to have a relative loose linkage with corporate strategy. Instead, commitment and enthusiasm can become powerful drivers of a CSR when corporate strategy is inherently socially valuable, and a company’s decision makers put social value of corporate strategy at the core of both internal and external communication.
Corporate Governance Convergence Through Cross-Border Mergers: The Case of Aventis

In this paper we illustrate the role of cross-border mergers in the process of corporate governance convergence. We explore in detail the corporate governance provisions in Rhone-Poulenc, a French company, and Hoechst, a German firm, and the resulting structure after the two firms merged in 1999 to create Aventis, legally a French corporation. We show that, despite the nationality of the firm, the corporate governance structure of Aventis is a combination of the corporate governance systems of Hoechst and Rhone-Poulenc, where the newly merged firm adopted the most protective provisions of the two merging firms. In some cases this resulted in Aventis' borrowing from the corporate governance structure of Hoechst while in others Aventis replicated Rhone-Poulenc's structure. Most interesting is the situation where Aventis introduced improved provisions over both systems. The resulting corporate governance system in Aventis is significantly more protective than the default French legal system of investor protection.
Semi-omnidirectional dual-polarized wideband multiport antennas for MIMO applications in Random-LOS and RIMP

We present two configurations of multiport antennas for Multiple-input Multiple-output (MIMO) application. The configurations are comprised of three and four dual-polarized self-grounded bowtie antenna as the element, respectively. The MIMO performance of both antennas is evaluated in Random Line-of-Sight (Random-LOS) and Rich Isotropic Multipath (RIMP) channel models as two edge propagation environments. Both configurations provide 360° azimuth and 120° elevation angular coverage in Random-LOS and full sphere coverage in RIMP. Using digital threshold receiver model and Zero-Forcing receiver, the performances of both configurations are evaluated in terms of Probability of Detection (PoD) and MIMO multiplexing efficiency calculated at 95% PoD level. The simulated results show a good performance for both structures in two edge environments, which can be concluded as a good performance in a real life situation.
Social-Aware Resource Allocation for Content Dissemination Networks: An Evolutionary Game Approach

Recently, the increasing popularity of local area services, such as YouTube, Facebook, and Twitter, on which thousands of clients subscribe and download popular contents all the while, has drawn more and more attention on the study of content dissemination networks. Device-to-device (D2D) communication, which allows two devices to directly communicate with each other, has become an effective content dissemination method. With the goal of reducing the delay of content dissemination process with D2D communication, we propose an evolutionary game (EG)-based distributed resource allocation scheme. Moreover, we theoretically prove the existence and stability of game equilibrium and further propose a global search algorithm to achieve equilibrium. In the algorithm, all D2D links will select resource adaptively based on the predicted contact duration. Aiming at improving the prediction accuracy of contact duration, we propose social trajectory similarity (STS) to represent the overlapping of history trajectory among all the mobile users by mining user behavior patterns. Numerical results show that our proposed STS increases nearly 20% correlation with history trajectory overlap compared with jaccard index. Furthermore, our EG-based scheme reduces the delay over 15% compared with the coalition game scheme, and over 30% compared with the random selection scheme. In addition, our proposed scheme also increases throughput efficiency with nearly 20% and achieves better fairness.
Going concern opinions are not bad news: Evidence from industry rivals

This paper examines whether going concern audit opinions (GCO) affect the stock price performance of the announcing firms and their industry rivals. Our original evidence clearly suggests that such accounting event is asymmetrically perceived by the market depending on whether the firm is qualified by the auditor or not. In particular, firms receiving a GCO earn negative abnormal returns at the audit report’s disclosure date and over the following year whereas their industry rivals exhibit positive abnormal returns at the GCO date and in the subsequent one-month period. This is in contrast with the preevent abnormal returns, which, on average, are negative and significant for all firms operating within the industry. Overall, we highlight the relevance of audit opinions and mandatory accounting information for the timing of transactions in financial markets.
A solution algorithm to the inverse kinematic problem for redundant manipulators

Based on a recently proposed algorithmic solution technique, the inverse kinematic problem for redundant manipulators is solved. The kinematics of the manipulator is appropriately augmented to include mentioned constraints; the result is an efficient, fast, closed-loop algorithm which only makes use of the direct kinematics of the manipulator. Simulation results illustrate the tracking performance for a given trajectory in the Cartesian space, while guaranteeing a collision-free trajectory and/or not violating a mechanical joint limit. >
Analysis of power consumption in consumer ADSL modems

This report describes an experiment carried out to understand how traffic transfer affects power consumption on consumer-grade adsl modems. Three ADSL modems were studied: a Linksys AG041, a Cisco 837 and a Netgear DG834G. Parallel streams of data were sent between a client and a server PC and the effect on power consumption by the routers was recorded. We discovered that there was almost no difference in the amount of power drawn from the routers with regards to the amount of data transferred or the duration of transfer. We did determine that the Linksys AG041 draws significantly more power than the other two routers.
Ydj1 but not Sis1 stabilizes Hsp70 protein under prolonged stress in vitro

Yeast cytosol has two important co‐chaperons; Ydj1 and Sis1. Genetic experiments showed that Ydj1 is not essential for viability; however, cells lacking it grow very poorly at 30°C or unable to grow at extreme temperatures. On the other hand, Sis1 is an essential protein and apparently plays a functional role at assembly or disassembly of protein complexes. Stability experiments revealed that only Ydj1‐protected Hsp70 proteins can hydrolyze ATP under prolonged stress. © 2007 Wiley Periodicals, Inc. Biopolymers 89: 171–174, 2008.
A case study of a WDM agent

This paper presents a case study of the development of a WDM agent for the control of two prototype photonic network elements, an optical add/drop multiplexer and an optical cross-connect. Even though the hardware developed for these prototypes is too small for a commercial device, the software is fully featured, and with modifications, could support devices of many times the complexity of the prototypes. The agent is developed using a WDM information model developed at Alcatel, and supports two kinds of protection.
Comments on "A unitary model of pitch perception" [J. Acoust. Soc. Am. 102, 1811-1820 (1997)].

Meddis and O’Mard have recently presented a revised autocorrelogram model of pitch perception, which they claim can account for the different pattern of experimental results obtained for complex tones consisting of resolved and unresolved harmonics. This Letter demonstrates that, in contrast to the experimental data, important features of the model’s output and predictions vary with frequency region rather than with resolvability.
Bilateral Superficial Cervical Plexus Block Alone or Combined with Bilateral Deep Cervical Plexus Block for Pain Management After Thyroid Surgery

Background and Objectives: Patients undergoing thyroid surgery need postoperative pain management. Bilateral superficial cervical plexus block (BSCBs) has been shown to improve postoperative analgesia. The objective of this study was to assess its analgesic efficacy in the first 24 hours after thyroid surgery alone and when combined with bilateral deep cervical plexus block (BDCBs). Methods: We performed a prospective randomized and controlled study that compared 3 equal parallel groups, 12 patients each: Group A, received (BSCBs) before surgery and under general anaesthesia with 10 ml of bupivacaine 0.5% and epinephrine 1:200.000 in each side. Group B received (BSCBs) as in group A with (BDCBs) with 5 ml bupivacaine 0.5 % and epinephrine 1:200,000 at the level of C3. Group C: received general anaesthesia without any block. Postoperative pain was assessed by the use of a 0-10 numeric rating scale. All patients received paracetamol every 6 hours. Morphine was administered following a standardized protocol if the numeric rating scales was 4 or higher. The main outcome variables were the proportion of patients given morphine during the 24 hours postoperatively, pain intensity scores, and total morphine consumption. Results: There was no significant difference among the 3 groups as regards their demographic data. Both groups A&B were significantly superior to the controlled group C as regards percentage of patient required morphine, pain scores and postoperative morphine consumption. In comparison between groups A&B, there was no significant difference between the 2 groups as regards the main outcome variables. (P < 0.05). Conclusion: Bilateral deep cervical plexus block does not add significant analgesic efficacy or has a narcotic saving strategy when combined with bilateral superficial cervical plexus block for pain control after thyroid surgery.
Force control of a two-arm robot: implementation on a multiprocessor architecture

Presents some practical solutions chosen to implement the force control of a two-arm robot on a multiprocessor architecture. The force control considered is the symmetric hybrid control proposed by M. Uchiyama and P. Dauchez (1987) for the manipulation of a single rigid object firmly held by two arms. The authors recall the definitions of the controlled vectors in this case. They present their experimental setup which includes two six-axis PUMA arms, equipped with two six-axis force sensors, and a multiprocessor controller based on a VME bus. The main part of the paper deals with the implementation of the hybrid control on the equipment and emphasizes: (i) the modifications of the control scheme; and (ii) the programming solutions used for reducing the computation time. Some preliminary experimental results and directions for future work are included. <<ETX>>
The animal species–body size distribution of Marion Island

Body size is one of the most significant features of animals. Not only is it correlated with many life history and ecological traits, but it also may influence the abundance of species within, and their membership of, assemblages. Understanding of the latter processes is frequently based on a comparison of model outcomes with the frequency of species of different body mass within natural assemblages. Consequently, the form of these frequency distributions has been much debated. Empirical data usually concern taxonomically delineated groups, such as classes or orders, whereas the processes ultimately apply to whole assemblages. Here, we report the most complete animal species–body size distribution to date for those free-living species breeding on sub-Antarctic Marion Island and using the terrestrial environment. Extending over 15 orders of magnitude of variation in body mass, this distribution is bimodal, with separate peaks for invertebrates and vertebrates. Under logarithmic transformation, the distribution for vertebrates is not significantly skewed, whereas that for invertebrates is right-skewed. Contrary to expectation based on a fractal or pseudofractal environmental structure, the decline in the richness of species at the smallest body sizes is a real effect and not a consequence of unrecorded species or of species introductions to the island. The scarcity of small species might well be a consequence of their large geographic ranges.
Space-time trellis coded OFDM system with added pilot semi-blind iterative channel estimation

Various channel estimation methods for multiple-input multiple-output (MIMO) systems have been proposed. In this paper, to prevent performance degradation for the space-time trellis coded OFDM (STTC-OFDM) system in fast fading channels, we propose a system that applies the added pilot semi-blind (APSB) channel estimation to all the OFDM data symbols except the preamble of a frame. We also propose a simplified system that applies the APSB channel estimation to the last OFDM symbol of a frame. We show that the proposed systems can track the channel variations without additional bandwidth because of the use of the APSB channel estimation and improve the word error rate (WER) performance compared to the conventional system that uses only DDCE.
Scalable coupling of Molecular Dynamics (MD) and Direct Numerical Simulation (DNS) of multi-scale ﬂows

The goal of this dCSE project was to develop the software infrastructure to couple high preformance ﬂuid and molecular dynamics solvers. This captures important details of localised ﬂuid ﬂow at the molecular level whilst preserving the eﬃciency of the continuum computation in the rest of the domain. The result is a veriﬁed and scalable library which links a continuum ﬂuid dynamics (CFD) code to a molecular dynamics code.
Identification of a new family of tissue-specific basic helix-loop-helix proteins with a two-hybrid system

With modified two-hybrid technology, we have isolated a member of a new family of basic helix-loop-helix (bHLH) transcription factors. Thing1 (Th1) was identified in a screen of a mouse embryo cDNA library as a partner for the Drosophila E protein daughterless. RNA in situ hybridization and reverse transcriptase-PCR demonstrate a stage- and tissue-specific distribution for the expression of Th1. Although tissue specific, the expression pattern of Th1 is fairly complex. During development, Th1 mRNA is widely expressed in extraembryonic tissues, portions of the heart, autonomic ganglia, the gut, and pharyngeal arches. At embryonic day 7.5 (E7.5), extraembryonic derivatives show robust Th1 expression. By E8.5, expression in the embryonic heart becomes detectable. During the next 2 days of development, the signal also includes gut and pharyngeal arches. Predominant expression at E13.5 is in neural crest derivatives, especially the autonomic nervous system and adrenal medulla. Expression of Th1 persists in the adult, in which it is localized to the smooth muscle cells of the gut. In vitro, Th1 protein recognizes a set of DNA sites that are more degenerate than has been determined for other bHLH factors, indicating a reduced binding specificity. Transient transfection of NIH 3T3 cells with GAL4-Th1 fusions reveals a repression activity mediated by the Th1 bHLH domain. In combination, these properties define Th1 as a new bHLH protein with a unique set of properties.
