    Full Text Available It gives me great pleasure to interview Dr. Hyeon-Shik Hwang, an innovative orthodontist who has developed many creative techniques over his career. Dr. Hwang was born in Korea and received his DDS and PhD degrees from Yonsei University in Seoul. He is professor and chairman of the Department of Orthodontics at Chonnam National University School of Dentistry, Gwangju, Korea. Dr. Hwang, as a faculty at the university hospital, has maintained a successful clinical practice for more than 25 years. He has treated many adult patients focusing on esthetics and periodontal health and has developed many clinical techniques to improve the effectiveness and efficiency of treatment to the benefit of both the patient and practitioner. Dr. Hwang is also interested in the evaluation of facial asymmetry two- and three-dimensionally. As one of the early adopters of cone-beam volume imaging, he has given special emphasis on the management of surgical cases. He is married to Jung-Un Park with whom he has two sons. His favorite hobbies are photography and listening to music. When I was presented to him in a congress, it was a great pleasure meeting someone who I already admired for his singular work. Later on, his humbleness and knowledge made me marvel at him even more. I hope that all readers of Dental Press Journal of Orthodontics also enjoy the teachings from this brilliant Korean orthodontist! Guilherme Thiesen - interview coordinator

    2016-01-01

    Combined use of a hearing aid (HA) and cochlear implant (CI) has been shown to improve CI users’ speech and music performance. However, different hearing devices, test stimuli, and listening tasks may interact and obscure bimodal benefits. In this study, speech and music perception were measured in bimodal listeners for CI-only, HA-only, and CI + HA conditions, using the Sung Speech Corpus, a database of monosyllabic words produced at different fundamental frequencies. Sentence recognition was measured using sung speech in which pitch was held constant or varied across words, as well as for spoken speech. Melodic contour identification (MCI) was measured using sung speech in which the words were held constant or varied across notes. Results showed that sentence recognition was poorer with sung speech relative to spoken, with little difference between sung speech with a constant or variable pitch; mean performance was better with CI-only relative to HA-only, and best with CI + HA. MCI performance was better with constant words versus variable words; mean performance was better with HA-only than with CI-only and was best with CI + HA. Relative to CI-only, a strong bimodal benefit was observed for speech and music perception. Relative to the better ear, bimodal benefits remained strong for sentence recognition but were marginal for MCI. While variations in pitch and timbre may negatively affect CI users’ speech and music perception, bimodal listening may partially compensate for these deficits. PMID:27837051

  6. A Comprehensive Trainable Error Model for Sung Music Queries

    CERN Document Server

    Birmingham, W P; 10.1613/jair.1334

    2011-01-01

    We propose a model for errors in sung queries, a variant of the hidden Markov model (HMM). This is a solution to the problem of identifying the degree of similarity between a (typically error-laden) sung query and a potential target in a database of musical works, an important problem in the field of music information retrieval. Similarity metrics are a critical component of query-by-humming (QBH) applications which search audio and multimedia databases for strong matches to oral queries. Our model comprehensively expresses the types of error or variation between target and query: cumulative and non-cumulative local errors, transposition, tempo and tempo changes, insertions, deletions and modulation. The model is not only expressive, but automatically trainable, or able to learn and generalize from query examples. We present results of simulations, designed to assess the discriminatory potential of the model, and tests with real sung queries, to demonstrate relevance to real-world applications.

    For bimodal cochlear implant users, acoustic and electric hearing has been shown to contribute differently to speech and music perception. However, differences in test paradigms and stimuli in speech and music testing can make it difficult to assess the relative contributions of each device. To address these concerns, the Sung Speech Corpus (SSC) was created. The SSC contains 50 monosyllable words sung over an octave range and can be used to test both speech and music perception using the same stimuli. Here SSC data are presented with normal hearing listeners and any advantage of musicianship is examined.

    2009-02-01

    The two hemispheres of the brain play complementary roles in song perception, with the left hemisphere specialized for processing the linguistic aspects of song and the right hemisphere specialized for the processing of melody. However, very little is known about how language and melody interact. The present study tested the hypothesis that right hemisphere linguistic processing would be facilitated by the presence of melody. In a dichotic listening paradigm, participants (8 men, 43 women) performed a linguistic task while listening to spoken or sung speech. Contrary to the hypothesis, left hemisphere specialization for linguistic processing was identical whether the sentences were spoken or sung.

  9. Denotation and connotation in public representation: Semantic network analysis of Hwang supporters' internet dialogues.

    2013-04-01

    This article analyzes the internet discourses of Korean people who supported Hwang Woo Suk despite the disclosure of his scientific misconduct. During the controversial period, those who supported Hwang constructed a narrative of a fallen hero trapped by jealous rivals and an "unjust" society. The supporters' dramatized discourses compete with expert opinions of Seoul National University's Audit Board and prosecutors that investigated the scientific fraud. By introducing and applying an innovative method of semantic network analysis, this study explores how the supporters represent their personal concerns in daily life and latent social problems in South Korea, as well as the failure of science communication. In short, the supporters' internet representations connote concerns in daily life that motivated their sympathy and activism for Hwang.

  10. Ethical modernization: research misconduct and research ethics reforms in Korea following the Hwang affair.

    2013-06-01

    The Hwang affair, a dramatic and far reaching instance of scientific fraud, shocked the world. This collective national failure prompted various organizations in Korea, including universities, regulatory agencies, and research associations, to engage in self-criticism and research ethics reforms. This paper aims, first, to document and review research misconduct perpetrated by Hwang and members of his research team, with particular attention to the agencies that failed to regulate and then supervise Hwang's research. The paper then examines the research ethics reforms introduced in the wake of this international scandal. After reviewing American and European research governance structures and policies, policy makers developed a mixed model mindful of its Korean context. The third part of the paper examines how research ethics reform is proactive (a response to shocking scientific misconduct and ensuing external criticism from the press and society) as well as reactive (identification of and adherence to national or international ethics standards). The last part deals with Korean society's response to the Hwang affair, which had the effect of a moral atomic bomb and has led to broad ethical reform in Korean society. We conceptualize this change as ethical modernization, through which the Korean public corrects the failures of a growth-oriented economic model for social progress, and attempts to create a more trustworthy and ethical society.

    Korean war in 1950's has great influence on Korean literature. Hwang Soon-Won's novels portray the flow of history that contains Korean war and division (South and North Korea). Disintegration of personality, psychological frigidity, and pressure from poverty, pain of family separation caused by the war are well depicted in his works. But his literary accomplishment as the novelist, is showing how the traumatic experiences caused by the Korean War can be healed through humanity, with artistic...

    We examine the argumentative structure of Hwang et al.’s (2004) paper about human somatic cell nuclear transfer (SCNT, or ‘therapeutic cloning’), contrasted with four Journalistic Reported Versions (JRV) of it, and with students’ summaries of one JRV. As the evaluation of evidence is one of the critical features of argumentation (Jiménez-Aleixandre 2008), the analysis focuses on the use of evidence, drawing from instruments to analyze written argumentation (Kelly et al. 2008) and from studies about the structure of empirical research reports (Swales 2001). The objectives are: 1) To examine the use of evidence and the argumentative structure of Hwang et al.’s Science, 303: 1669-1674 (2004) original paper in terms of the criteria: a) pertinence of the evidence presented to the claims; b) sufficiency of the evidence for the purpose of supporting the claims; and c) coordination of the evidence across epistemic levels. 2) To explore how the structure of Hwang’s paper translates into the JRV and into university students’ perceptions about the evidence supporting the claims. The argumentative structure of Hwang’s paper is such that its apparently ostensible main claim about NT constitutes a justification for a second claim about its therapeutic applications, for which no evidence is offered. However, this second claim receives prominent treatment in the JRV and in the students’ summaries. Implications for promoting critical reading in the classroom are discussed.

    Words and melodies are some of the basic elements infants are able to extract early in life from the auditory input. Whether melodic cues contained in songs can facilitate word-form extraction immediately after birth remained unexplored. Here, we provided converging neural and computational evidence of the early benefit of melodies for language acquisition. Twenty-eight neonates were tested on their ability to extract word-forms from continuous flows of sung and spoken syllabic sequences. We found different brain dynamics for sung and spoken streams and observed successful detection of word-form violations in the sung condition only. Furthermore, neonatal brain responses for sung streams predicted expressive vocabulary at 18 months as demonstrated by multiple regression and cross-validation analyses. These findings suggest that early neural individual differences in prosodic speech processing might be a good indicator of later language outcomes and could be considered as a relevant factor in the development of infants' language skills.

    Full Text Available Spotted hyaena Crocuta crocuta are known to be opportunists and to have a varied diet including mammals, reptiles and birds. Prey most often hunted are medium sized ungulates but spotted hyaenas will on occasion take larger species such as giraffe Giraffa camelopardalis and zebra Equus burchellii. They are also known to hunt whichever species are most abundant and will vary their prey seasonally. In this study spotted hyaenas were observed to take an unusual prey species in the form of elephant calves (Loxodonta africana. On a number of occasions hyaenas were observed feeding on or killing newborn and very young elephant calves. These observations were made whilst the authors were conducting research on spotted hyaena ecology in the woodlands of Hwange National Park, Zimbabwe and were made during the dry season between September and November 1999.

    Full Text Available Acupuncture has fairly good weight-reducing effect in treating simple obesity due to the neuroendocrine regulation. In this study, the anti-obesity effects of herbal acupuncture (HA with Sang-hwang (Phellinus linteus at Fuai (SP16 were investigated in the rat fed on high-fat (HF diet. Sang-hwang mushroom has been proven to have anti-carcinogenic effects and Sang-hwang extracts are highly effective in treatment and preventive treatment of AIDS, diabetes and high blood-pressure. To determine whether the Sang-hwang herbal acupuncture may have the anti-obesity effect, male Sprague-Dawley (4-wk-old rats were fed a HF diet for 5 wk, which produced significant weight gain compared to rats were fed a normal diet, and then herbal acupuncture were treated for 3 wk in HF diet group. The body weight, food consumption, food effeciency ratio (FER, body fat mass, plasma nitric oxide (NO were investigated in rats fed on normal diet, HF diet, and HF diet with HA (HF-diet-HA groups. NO has been proposed to be involved in the regulation of food intake. In addition, the expression of appetite peptides such as orexigenic peptide neuropeptide Y (NPY and the anorectic peptide cholecystokinin (CCK were observed in the hypothalamus. HF-HA group reduced body weight gain, FER, body fat contents and NO concentration compared to HF diet group. The expression of NPY was reduced in arcuate nucleus (ARC, and CCK was increased in the paraventricular nucleus (PVN after treatment of HA. In conclusion, Sang-hwang HA reduced adipocity, plasma NO and hypothalamic NPY, but increased CCK expression in the HF diet-induced obesity rat, therefore HA may have anti-obesity action through regulating body weight and appetite peptide of the central nervous system.

    2014-01-01

    Previous studies have suggested that presenting to-be-memorised lyrics in a singing mode, instead of a speaking mode, may facilitate learning and retention in normal adults. In this study, seven healthy older adults and eight participants with mild Alzheimer's disease (AD) learned and memorised lyrics that were either sung or spoken. We measured the percentage of words recalled from these lyrics immediately and after 10 minutes. Moreover, in AD participants, we tested the effect of successive learning episodes for one spoken and one sung excerpt, as well as long-term retention after a four week delay. Sung conditions did not influence lyrics recall in immediate recall but increased delayed recall for both groups. In AD, learning slopes for sung and spoken lyrics did not show a significant difference across successive learning episodes. However, sung lyrics showed a slight advantage over spoken ones after a four week delay. These results suggest that singing may increase the load of initial learning but improve long-term retention of newly acquired verbal information. We further propose some recommendations on how to maximise these effects and make them relevant for therapeutic applications.

    2012-01-01

    Full Text Available Abstract Background Gyejibongnyeong-hwan (GJBNH is one of the most popular Korean medicine formulas for menstrual pain of dysmenorrhea. The concept of blood stagnation in Korean medicine is considered the main factor of causing abdominal pain, or cramps, during menstrual periods. To treat the symptoms, GJBNH is used to fluidify the stagnated blood and induce the blood flow to be smooth, reducing pain as the result. The purpose of this trial is to identify the efficacy of GJBNH in dysmenorrhea caused by blood stagnation. Methods This study is a multi-centre, randomised, double-blind, controlled trial with two parallel arms: the group taking GJBNH and the group taking placebo. 100 patients (women from age 18 to 35 will be enrolled to the trial. Through randomization 50 patients will be in experiment arm, and the other 50 patients will be in control arm. At the second visit (baseline, all participants who were already screened that they fulfil both the inclusion and the exclusion criteria will be randomised into two groups. Each group will take the intervention three times per day during two menstrual cycles. After the treatment for two cycles, each patient will be followed up during their 3rd, 4th and 5th menstrual cycles. From the screening (Visit 1 through the second follow-up (Visit 6 the entire process will take 25 weeks. Discussion This trial will provide evidence for the effectiveness of GJBNH in treating periodical pain due to dysmenorrhea that is caused by blood stagnation. The primary outcome between the two groups will be measured by changes in the Visual Analogue Score (VAS of pain. The secondary outcome will be measured by the Blood Stagnation Scale, the Short-form McGill questionnaire and the COX menstrual symptom scale. Analysis of covariance (ANCOVA and repeated measured ANOVA will be used to analyze the data analysis. Trial registration Current Controlled Trials: ISRCTN30426947

  1. Perceptions on climate change and its impact on livelihoods in Hwange district, Zimbabwe

    2014-03-01

    Full Text Available This study investigated perceptions of rural communities on climate change and its impacts on livelihoods. The research was conducted in the semi-arid Hwange district in Matebelel and North province of Zimbabwe. The perceptions were compared with empirical evidence from climatic studies on trends on temperature and rainfall, and impacts on livelihoods in the country and region. The findings from the current study are generally in agreement with those of other studies that indicate changes in the climate, especially in terms of rainfall. This largely applies to short-term periods; however, for long-term periods it is difficult to accurately relate rural community perceptions to changes in rainfall over time. Despite perceived changes and impacts of climate change on local livelihood activities, mainly agriculture, there are multiple stressors that the communities face which also affect their livelihoods. Further evidence-based research is required to disentangle climate change impacts on livelihoods, including livelihood impacts arising from interactions of climate and non-climatic factors.

    2015-10-01

    Full Text Available There is emerging evidence to demonstrate the efficacy of music based interventions for improving social functioning in children with Autism Spectrum Disorders (ASD. While this evidence lends some support in favour of using song over spoken directives in facilitating engagement and receptive intervention in ASD, there has been little research that has investigated the efficacy of such stimuli on socio-communicative responsiveness measures. Here, we present preliminary results from a pilot study which tested whether sung instruction, as compared to spoken directives, could elicit greater number of socio-communicative behaviours in young children with ASD. Using an adapted single-subject design, three children between the ages of 3 and 4 years, participated in a programme consisting of 18 sessions, of which 9 were delivered with spoken directives and 9 with sung. Sessions were counterbalanced and randomized for three play activities - block matching, picture matching and clay play. All sessions were video-recorded for post-hoc observational coding of three behavioural metrics which included performance, frequency of social gesture and eye contact. Analysis of the videos by two independent raters indicated increased socio-communicative responsiveness in terms of frequency of social gesture as well as eye contact during sung compared to spoken conditions across all participants. Our findings suggest that sung directives may play a useful role in engaging children with ASD and also serve as an effective interventional medium to enhance socio-communicative responsiveness.

    Full Text Available Language and music, two of the most unique human cognitive abilities, are combined in song, rendering it an ecological model for comparing speech and music cognition. The present study was designed to determine whether words and melodies in song are processed interactively or independently, and to examine the influence of attention on the processing of words and melodies in song. Event-Related brain Potentials (ERPs and behavioral data were recorded while non-musicians listened to pairs of sung words (prime and target presented in four experimental conditions: same word, same melody; same word, different melody; different word, same melody; different word, different melody. Participants were asked to attend to either the words or the melody, and to perform a same/different task. In both attentional tasks, different word targets elicited an N400 component, as predicted based on previous results. Most interestingly, different melodies (sung with the same word elicited an N400 component followed by a late positive component. Finally, ERP and behavioral data converged in showing interactions between the linguistic and melodic dimensions of sung words. The finding that the N400 effect, a well-established marker of semantic processing, was modulated by musical melody in song suggests that variations in musical features affect word processing in sung language. Implications of the interactions between words and melody are discussed in light of evidence for shared neural processing resources between the phonological/semantic aspects of language and the melodic/harmonic aspects of music.

    黄哲伦( David Henry Hwang)是美国当代著名的华裔剧作家。《蝴蝶君》一剧让他声名大噪,并确立了他在戏剧界的地位,同时他也因此剧受到了国内学者的关注。从2000年国内就开始有了关于他的研究,并且研究数量逐年增加,其中不乏一些值得重视的观点。但是笔者经总结发现,关于黄哲伦的研究主要集中于他的《蝴蝶君》上,其他作品研究相对较少,内容主要集中于对其写作主题及思想的研究。本文通过对国内这一领域的研究现状与研究特点进行考察,试图发现我国对黄哲伦研究在理论方法、研究视角与关注侧重等方面呈现出的特点,以及存在的不足并找出新的研究空间。%David Henry Hwang is a famous contemporary Chinese-American playwright whose play M. Butterfly has earned him world-wide fame and reputation in the theater. Thereafter, he is paid attention to by the domestic scholars mainly for this play. Since 2000, studies about Hwang and his works have begun and the number has been increasing gradually. However, after careful analysis, the paper finds that most of researches about Hwang are focused on M. Butterfly and only a few are concerned about his other works. In addition, the contents are about his writing themes. Therefore, this article tries to find the insufficiency in literary methods and research perspectives and new rooms about Hwang's research by analyzing the domestic research status and features.

    Some Korean and oriental herbal prescriptions used for a syndrome expressed as chest paralysis and heartache are thought to be effective for angina pectoris. We investigated the effects of an oriental medicinal prescription, Geiji-Bokryung-Hwan (GBH) consisting of herbs of Cinnamomi Ramulus, Poria Cocos Hoelen (Pachymae Fungus), Moutan Cortex Radicis, Paeoniae Radix, and Persicae Semen, on growth-inhibitory activity and cancer chemopreventive activity in assays representing three major stages of carcinogenesis. The GBH was found to act as an potent inhibitor of cyclooxygenase (COX)-1 only but not as COX-2 inhibitor. Furthermore, the extract mediated anti-inflammatory effects and inhibited COX-associated hydroperoxidase functions (anti-promotion activity). Inhibitory effect of the GBH on the growth of cancer cell lines such as HepG2 cell and Hep3B cell was shown. These data suggest that GBH extracts merit investigation as a potential cancer chemopreventive agent in humans, especially in hepatological cancers.

    40Ar-39Ar analyses of one alkali pyroxenite whole rock and two phlogopite separates of calcite carbonatites from the Sung Valley carbonatite-alkaline complex, which is believed to be a part of the Rajmahal-Bengal-Sylhet (RBS) ood basalt province, yielded indistinguishable plateau ages of 108.8 ± 2.0 Ma, 106:4 ± 1.3 Ma and 107.5 ± 1.4 Ma, respectively. The weighted mean of these ages, 107.2 ± 0.8 Ma, is the time of emplacement of this complex. This implies that Sung Valley complex and probably other such complexes in the Assam-Meghalaya Plateau postdate the main ood basalt event (i.e., the eruption of tholeiites) in the RBS province by ∼10 Ma.

    This paper deals with cerebral paragonimiasis and cerebral hemispherectomy conducted as a treatment of cerebral paragonimiasis by Bo Sung Sim in Korea in 1950s-1960s. He demonstrated that cerebral hemispherectomy could be used for unilateral diffuse cerebral paragonimiasis. Sim learned cerebral hemispherectomy from Dr. L. A. French. at the University of Minnesota from 1955 to 1957 in America. The authors argues that Bo Sung Sim's introduction of cerebral hemispherectomy to Korea was not a simple application of an advanced medical technology, but a complicated and active process in that Sim used the technique to intervene intractable complications from cerebral paragonimiasis such as generalized convulsions, spastic hemiplegia and mental deterioration. Bo Sung Sim, one of the neurosurgeons of the first generation in Korea, was trained in neurology, neuropathology, neuroradiology and animal experiments as well as in neurosurgery at the University of Minnesota. After returning to Korea, Sim faced parasitic diseases, one of the most serious public health problems at that time, which were far different from what he learned in America. As a neurosurgeon, Sim tackled with parasitic diseases of the central nervous system with various diagnostics and therapeutics. In 1950s, more than one million populations suffered from pulmonary paragonimiasis acquired by eating raw crabs or by feeding juice of crushed crayfish for the treatment of measles in Korea. About 26.6 percent of people with paragonimiasis had cerebral paragonimiasis. Before bithionol therapy was introduced in 1962, neurosurgery was the only available treatment to control increased intracranial pressures, intractable epilepsy, paralysis and mental deterioration. Between 1958 to 1962, Bo Sung Sim operated on 24 patients of cerebral paragonimiasis. In two of them, he performed cerebral hemispherectomy to control intractable convulsions when he found diffuse cerebral paragonimiasis and cerebral atrophy at the

    In a recent preprint cond-mat/9812216, Das Sarma and Hwang propose an explanation of the sharp decrease in resistivity at low temperatures which has been attributed to a transition to an unexpected conducting phase in dilute high-mobility two-dimensional systems at B=0. In this Comment, we examine whether their model is supported by the available experimental data.

    Geiji-Bokryung-Hwan (GBH), consisting of herbes of Cinnamomi ramulus (Geiji), Poria cocos (Bokryun), Mountan cortex radicis (Mokdanpi), Paeoniae radix (Jakyak), and Persicae semen (Doin), on antiplatelet activity in human platelet suspensions was studied. The mechanism involved in the antiplatelet activity of GBH in human platelet suspensions was investigated. GBH did not significantly affect the thromboxane synthetase activity of aspirin-treated platelet microsomes and GBH (15 and 30 microg/ml) significantly inhibited [3H]arachidonic acid released in collagen-activated platelets but not in unactivated-platelets. Nitric oxide (NO) production in human platelets was measured by a chemiluminesence detection method in this study. GBH did not significantly affect nitrate production in collagen (10 microg/ml)-induced human platelet aggregation. Various concentrations of GBH (0, 5, 10, 15, and 30 microg/ml) dose-dependently inhibited [3H]inositol monophosphate formation stimulated by collagen (10 microg/ml) in [3H]myoinositol-loaded platelets at different incubation times (1, 2, 3, and 5 min). These results indicated that the antiplatelet activity of GBH may possibly be due to the inhibition of phospholipase C (PLC) activity, leading to reduce phosphoinositide breakdown, followed by the inhibition of thromboxane A(2) formation, and then inhibition of [Ca(2+)](i) mobilization of platelet aggregation stimulated by agonists. In conclusion, GBH suppressed PLC in a dose-dependent manner, and may have pharmaceutical applications. These data suggest that GBH extracts merit investigation as a potential anti-atherosclerogenic agent in humans.

    Bo-yang-hwan-o-tang (BHT) is an oriental herbal medicine for treating brain disorders such as cerebral ischemia. The objective of this study was to develop an economically feasible and time-saving high-throughput screening method to monitor the potential inhibitory effects of BHT on human cytochrome P450 (CYP) enzymes in vitro. Two cocktail sets were used for incubation of human liver microsomes: Cocktail A: 6 probe substrates for CYP1A2, CYP2A6, CYP2C8, CYP2C19, CYP2D6, CYP3A4; Cocktail B: 3 for CYP2B6, CYP2C9, CYP2E1. The concentrations of the substrate metabolites were simultaneously analyzed using UPLC/MS/MS. The BHT extract had almost negligible inhibitory effects on the nine human CYP isoforms tested, with the half-maximal inhibitory concentration value ranged from 3624.99 to 45412.44 μg/ml. The results suggest that BHT extract has no inhibitory effects on CYP isoforms within the clinically recommended dosage range. We conclude that BHT might be free of drug-herb interactions when co-administered with other medicines. However, more in vivo human studies are needed to confirm these results. The high-throughput screening method can be a useful tool for drug discovery and for understanding drug interactions.

  17. Acoustic Features and Perceptive Cues of Songs and Dialogues in Whistled Speech: Convergences with Sung Speech

    CERN Document Server

    Meyer, Julien

    2007-01-01

    Whistled speech is a little studied local use of language shaped by several cultures of the world either for distant dialogues or for rendering traditional songs. This practice consists of an emulation of the voice thanks to a simple modulated pitch. It is therefore the result of a transformation of the vocal signal that implies simplifications in the frequency domain. The whistlers adapt their productions to the way each language combines the qualities of height perceived simultaneously by the human ear in the complex frequency spectrum of the spoken or sung voice (pitch, timbre). As a consequence, this practice underlines key acoustic cues for the intelligibility of the concerned languages. The present study provides an analysis of the acoustic and phonetic features selected by whistled speech in several traditions either in purely oral whistles (Spanish, Turkish, Mazatec) or in whistles produced with an instrument like a leaf (Akha, Hmong). It underlines the convergences with the strategies of the singing ...

    Two high-pitched and long sustained notes, F5 and A5, were selected from an aria found in ten commercial recordings of G Verdi's opera Aida by ten different sopranos. Both notes were sung without any instrumental accompaniment and with a crescendo. These audio examples were analyzed with regard to fundamental frequency, vibrato rate, vibrato extent, intonation and sound level, and the relationship among these parameters. The results reveal that vibrato rate differed significantly between the tones in most of the singers and confirm Prame's observations that vibrato rate tends to increase exponentially toward the end of tones. Moreover, both vibrato extent and mean F0 often varied systematically with sound level. The regularity of the vibrato tended to be greater at F5 than at A5.

    Hwang et al. (Antonie van Leeuwenhoek 109:1345-1352, 2016) proposed the reclassification of Halomonas caseinilytica (Wu et al. 2008) as a later synonym of Halomonas sinaiensis, based on the publication of the latter name in 2007 by Romano et al. However, the name H. sinaiensis was validly published only in 2011. Therefore the proposal by Hwang et al. is not appropriate; instead, the name H. sinaiensis can be proposed as a later synonym of H. casinilytica.

  1. The word and music of epic song: From syncretism to sung poetry

    Full Text Available This study concerns the relationship between verbal and musical components of Serbian epic songs with rhythm seen as a morphological dominant. My aim is to enrich the musicological inquiry of this issue and provide a contribution that complements existing folkloristic and philological research outcomes. In terms of methodology, the study promotes the necessity of recording the performers’ recited versions of songs for the purposes of investigating the relationships between verbal and musical communication, as well as an interdisciplinary approach to these issues. Two paradigmatic examples are examined, each performed by the guslar representative of his respective period of guslar practice: Tanasije Vućić (1883-1937 and Boško Vujačić (b. 1947. The observed periods span less than one century, yielding an insignificant passage of time in terms of epic historicism, but nonetheless indicate significant differences between these two guslars’ sung and narrated rhythms. Compared to Vujačić, Vućić’s singing demonstrates a considerably smaller range of the absolute duration of the sung syllables (and therefore of an entire verse, and subsequently a much stricter syllabicity. Furthermore, Vućić’s singing reflects the ideal type of “isochronous pulse in duple meter” in a rather high degree, while Vujačić more consistently refers to narration, whereas the trochaic tendency is noticeable only at the initial part of the verse. The connections between these focused individual styles are discussed through the lens of guslars’ transition from amateur to professional capacity and the changed function of epics. Considering the consequences of the policy of invalid representation and experiencing epic song as poetry (void of musical component, and on the other hand, the effects of the strategy insistent on “citatory” (verbatim treatment of poetic templates that leads to suppressing poetic creativity, I intend to draw attention of the

    Geiji-Bokryung-Hwan (GBH), a drug preparation consisting of five herbs of Cinnamomi Ramulus (Geiji), Poria Cocos (Bokryun), Mountan Cortex Radicis (Mokdanpi), Paeoniae Radix (Jakyak) and Persicae Semen (Doin), is a traditional Korean herbal medicine that is widely used in the treatment of atherosclerosis-related disorders. A water extract of GBH was found to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and inhibit low-density lipoprotein (LDL) oxidation more effectively than probucol, a well-known commercially available antioxidant. In order to evaluate the anti-atherogenic potential of this medication, New Zealand White (NZW) rabbits were fed a normal diet for 12 weeks, a high cholesterol diet, a high cholesterol diet containing 1% probucol or a high cholesterol diet containing 5% water-soluble extract of GBH. Both GBH and probucol reduced plasma cholesterol levels. LDLs from the GBH-treated group were more resistant to Cu(2+)-induced oxidation and contained more vitamin E than LDLs from the high cholesterol diet group. Endothelial damage, determined at week 6, was reduced by 55% in the GBH group (P<0.01). GBH treatment reduced an atherosclerotic area in the abdominal aorta by 58% (P<0.05) and cholesterol deposition in the thoracic aorta by 55% (P<0.05). The severity of atherosclerosis in the GBH group was significantly reduced after an adjustment using cholesterol exposure as an index of the cholesterol-lowering effect. On the other hand, diet-induced hyperlipidemic rabbits were given water extract of GBH in doses of 50 (Group B) and 200 mg/kg (Group C) and compared with controls (Group A). At 40 days after intervention in groups A, B and C, total and LDL cholesterol levels were significantly lowered (P<0.01). LDL/high density lipoprotein (HDL) ratio was also significantly decreased (P<0.01). This study concludes that the reduction in atherosclerosis by GBH relies not only on its cholesterol-lowering effect but also more heavily on its antioxidant

    Full Text Available This paper considers James McBride’s novel Song Yet Sung through multiple lenses – Bakhtin’s Carnivalesque, magic realism and performativity as it relates to race and gender identities. It is considered how the character of the “Dreamer” can be read clinically as suffering the sequelae of a traumatic brain injury. Her symptoms, which include future hallucinations or prophecies, can be read as neurological symptoms of her multiple head injuries documented in the novel. Connected to this reading, the influence of magic realism is considered, particularly as it relates to the natural imagery and symbolism in the novel. The importance of birds, in particular, is considered. Carnivalesque as conceptualized by Bakhtin is also considered in the context of “magical” thinking and reading, and its connections to social subversion; this is considered in relation to the era of slavery, its legacy, and associated issues of gender and race.Keywords: Carnivalesque, Magic Realism, Prophecy, Gender Performance, Racial Performativity, Identity Performance

    Neural correlates of the processing of musical syntax-like structures have been investigated via expectancy violation due to musically unrelated (i.e., unexpected) events in musical contexts. Previous studies reported the implication of inferior frontal cortex in musical structure processing. However - due to the strong musical manipulations - activations might be explained by sensory deviance detection or repetition priming. Our present study investigated neural correlates of musical structure processing with subtle musical violations in a musical priming paradigm. Instrumental and sung sequences ended on related and less-related musical targets. The material controlled sensory priming components, and differences in target processing required listeners' knowledge on musical structures. Participants were scanned with functional Magnetic Resonance Imaging (fMRI) while performing speeded phoneme and timbre identification judgments on the targets. Behavioral results acquired in the scanner replicated the facilitation effect of related over less-related targets. The blood oxygen level-dependent (BOLD) signal linked to target processing revealed activation of right inferior frontal areas (i.e., inferior frontal gyrus, frontal operculum, anterior insula) that was stronger for less-related than for related targets, and this was independent of the material carrying the musical structures. This outcome points to the implication of inferior frontal cortex in the processing of syntactic relations also for musical material and to its role in the processing and integration of sequential information over time. In addition to inferior frontal activation, increased activation was observed in orbital gyrus, temporal areas (anterior superior temporal gyrus, posterior superior temporal gyrus and sulcus, posterior middle temporal gyrus) and supramarginal gyrus.

    Full Text Available Singing is as natural as speaking for humans. Increasing evidence shows that the layman can carry a tune (e.g., when asked to sing a well-known song or to imitate single pitches, intervals and short melodies. Yet, important individual differences exist in the general population with regard to singing proficiency. Some individuals are particularly inaccurate or imprecise in producing or imitating pitch information (poor-pitch singers, thus showing a variety of singing phenotypes. Unfortunately, so far there is not a standard set of tasks for assessing singing proficiency in the general population, allowing to uncover and characterize individual profiles of poor-pitch singing. Different tasks and analysis methods are typically used in various experiments, making the comparison of the results across studies arduous. To fill this gap we propose here a new tool for assessing singing proficiency (the Sung Performance Battery, SPB. The SPB starts from the assessment of participants’ vocal range followed by five tasks: 1 single-pitch matching, 2 pitch-interval matching, 3 novel-melody matching, 4 singing from memory of familiar melodies (with lyrics and on a syllable, and 5 singing of familiar melodies (with lyrics and on a syllable at a slow tempo indicated by a metronome. Data analysis via acoustical methods provides objective measures of pitch accuracy and precision in terms of absolute and relative pitch. The SPB has been tested in a group of 50 occasional singers. The results indicate that the battery is useful for characterizing proficient singing and for detecting cases of inaccurate and/or imprecise singing.

    We examine whether the current regulatory regime instituted in South Korea and the United States would have prevented Hwang's potential transgressions in oocyte procurement for somatic cell nuclear transfer, we compare the general aspects and oversight framework of the Bioethics and Biosafety Act in South Korea and the US National Academies' Guidelines for Human Embryonic Stem Cell Research, and apply the relevant provisions and recommendations to each transgression. We conclude that the Act would institute centralized oversight under governmental auspices while the Guidelines recommend politically-independent, decentralized oversight bodies including a special review body for human embryonic stem cell research at an institutional level and that the Guidelines would have provided more vigorous protection for the women who had undergone oocyte procurement for Hwang's research than the Act. We also suggest additional regulations to protect those who provide oocytes for research in South Korea.

    Full Text Available With the emergence of research on real-time visual feedback to supplement vocal pedagogy, the utilization of technology in the world of music is now seen to accelerate skills learning and enhance cognitive development. The researchers of this project aim to further analyze vowel intelligibility and develop software applications intended to be used not only by professional singers but also by individuals who wish to improve their singing capability. Data in the form of sung vowels and song pieces were obtained from 46 singers. A Listening Test was then conducted on these samples to obtain the ground truth for vowel classification based on human perception. Simulation of the human auditory perception of sung Filipino vowels was performed using formant frequencies and Mel-frequency cepstral coefficients as feature vector inputs to a two-stage Discriminant Analysis classifier. The setup resulted in an over-all Training Set accuracy of 89.4% and an over-all Test Set accuracy of 90.9%. The accuracy of the classifier, measured in terms of the correspondence of vowel classifications obtained from the classifier with the results of the Listening Test, reached 92.3%. Using information obtained from the classifier, offline and online/real-time software applications were developed. The main application features include the display of the spectral envelope and spectrogram, pitch and vibrato analysis and direct feedback on the classification of the sung vowel. These features were recommended by singers who were surveyed and were incorporated in the applications to aid singers to adjust formant locations, directly determine listener’s perception of sung vowels, perform modeling effectively and carry out vowel migration.

    Full Text Available In dry biomes, spatio-temporal variation in surface water resource stocks is pervasive, with unknown effects on the ranging behaviour of large predators. This study assessed the effect of spatial variation in surface water resources on the ranging behaviour of the African wild dog (Lycaon pictus. We analyzed data for 1992 (dry year with 20 water points and 2000 (wet year with 30 water points against presence-only data for five packs of L. pictus in a part of Hwange National Park and adjacent smallholder communal farming areas in western Zimbabwe. Modelling the potential habitat for L. pictus using Maxent with distance from water points (Dw and Normalized Difference Vegetation Index (NDVI as predictor variables was successful for 2000 (AUC = 0.793 but not successful for 1992 (AUC = 0.423, with L. pictus probability of occurrence near water points being more for year 2000 than for year 1992. The predicted L. pictus range was wider in 1992 (~13888.1 km2 than in 2000 (~958.4 km2 (Test of Proportions, χ2 = 124.52, df = 1, P = 0.00. Using the 2nd order Multitype Nearest Neighbour Distance Function (Gcross, we also observed significant attraction between L. pictus and water points within only ~1km radius for 1992 but up to ~8km radius for 2000. Our study reinforced the notion that surface water resources attract wild dogs in the savannahs but paradoxically less so when water resources are scarce. In particular, our study furthers current understanding of the effects of changing water availability regimes on the endangered L. pictus, providing evidence that the endangered predator's home range encroaches into potential ecological traps (i.e., smallholder communal farming areas when water resources are scarce.

    2015-12-01

    In East Asia during the second half of the 19th century, overseas mission work by Protestant churches thrived. Missionaries built schools and hospitals and effectively used them for evangelism. In the 20th century when Social Gospel Movement was expanding, medical work has been recognized as a significant mission service in and by itself. This article reviewed the construction and characteristics of missions work conducted by Canadian Presbytery; missionary doctors and Korean doctors who worked at the mission hospitals; why the missionary medical work had to stop; and career paths taken by Korean doctors upon liberation from Japanese occupation. The Canadian Presbytery missionaries, unlike other denomination missionaries, were rather critical of Imperial Japan, but supportive towards Koreans. This could have stemmed from the reflection of their own experience of once a colony of British Empire and also their value system that promotes egalitarian, democratic and progressive theology. The Sung-jin and Ham-heung Mission Bases were a community, interacting organically as a 'Triangle of Church, School and Hospital.' The missionaries mobilized the graduates from Christian schools and organized a Young Men's Christian Association (YMCA). Some of the graduates were trained to become medical doctors or assistants and worked at mission hospitals. Missionary doctors' approaches to balancing evangelism and medical practice varied. For example, Robert Grieson went through confusion and struggled to balance conflicting roles as a pastor for evangelism and also as a physician. Kate McMillan, on the other hand, had less burden for evangelism than Grieson, and focused on medical work by taking advantage of the opportunity that, as a woman, she can easily approach Korean women. Still another case was Florence Murray who practised evangelism within the hospital setting, and successfully carried out the role as a hospital administrator, going beyond 'women's work' as McMillan did

    The processing of pitch intervals may be differentially influenced when musical or speech stimuli carry the pitch information. Most insights into the neural basis of pitch interval processing come from studies on music perception. However, music, in contrast to speech, contains a stable set of pitch intervals. To converge the investigation of pitch interval processing in music and speech, we used sequences of the same spoken or sung syllables. The pitch of these syllables varied either by semitone steps like in music or by smaller intervals. Participants had to differentiate the sequences according to their different sizes of pitch intervals or to the direction of the last frequency step in the sequence. The results depended strongly on the specific task demands. Whereas the interval-size task itself recruited more regions in right lateralized fronto-parietal brain network, stronger activity on semitone than on non-semitone sequences was found in the left hemisphere (mainly in frontal cortex) during this task. These effects were also influenced by the speech mode (spoken or sung syllables). Our findings suggest that the processing of pitch intervals in sequences of syllables depends on an interaction between bottom-up (speech mode, pitch interval) and top-down effects (task).

Owing to its personal and ethical nature, interna-tional community thinks highly of the rules and regulations of the egg for research. Ignoring the ethics of human eggs, the re-search team leaded by Korean scientist Hwang Woo-Suk collected and used human eggs for scientific research by illegal means, which caused the worldwide egg disturbance. Taking it as a mirror, South Korea learned lessons timely and enacted the Bioethics and Biosafety Act and modified repeatedly, as a positive response to Hwang's case. The revised version in 2008 per-fects relevant contents including egg donation and the research of embryonic stem cell. Analyzing and summarizing the South Korea's experience has certain significance for reference to our country.

    Full Text Available ABSTRACT Background : There are approximately 15,000 workers in several spurious eyelash industries in Purbalingga Regency. Since objects being observed are very fine and the tasks need high accuracy, good lighting is therefore highly required. Poor lighting can lead to visual and mental fatigue, stiffness around the eyes, eye damage and the increasing of work accidents. Sufficient intensity and good management of lighting will result a comfort environment in accordance  to achieve a safe  work environment. Method : This research was conducted as  observational study with a cross sectional approach  for 45 samples of workers. Sampling was carried out by using of systematic random sampling. Data of light intensity and reflectance were collected by measurement of light using Lux Meter and assessment of visual fatigue by using Retention Timer. Other data were collected by interviewing workers with age limitation up to 33 years old. Chi Square Test was used to analyze the data of light intensity and reflectance, work years, age, work period, distance of light to object, distance of eyes to object, relative humidity and temperature, and the correlation with the rise of visual fatigue. Result : Light intensity in the knitting section was between 301.5 – 576.7 lux with reflectance of 43.1%-89.6%. Thirty wokers (66.7% suffered from mild visual fatigue and fifteen wokers, suffered (33.3% from moderate visual fatigue. Light intensity had  an influence and significant relationship  to the occurring of visual fatigue among workers in the industry of spurious eyelash of  PT. Sung Shim International  (p < 0,05 with  Odd ratio = 10.246 (95% CI : 1.147 - 91.498.  Probability of light intensity factor to cause visual fatigue measured by a regression logistic model  was  82.9% . It was caused by  poor lighting (light intensities were measured  below 500 lux while 17.1%  was caused by  other factors. Conclusion : Most of the spurious eyelash

  13. Insights for integrated conservation from attitudes of people toward protected areas near Hwange National Park, Zimbabwe.

    Increase in human settlements at the edge of protected areas (PAs) is perceived as a major threat to conservation of biodiversity. Although it is crucial to integrate the interests of surrounding communities into PA management, key drivers of changes in local populations and the effects of conservation on local livelihoods and perceptions remain poorly understood. We assessed population changes from 1990 to 2010 in 9 villages located between 2 PAs with different management policies (access to natural resources or not). We conducted semi-directive interviews at the household level (n =217) to document reasons for settlement in the area and villager's attitudes toward the PAs. We examined drivers of these attitudes relative to household typology, feelings about conservation, and concerns for the future with mixed linear models. Population increased by 61% from 2000 to 2010, a period of political and economic crisis in Zimbabwe. Forty-seven percent of immigrants were attracted by the area; others had been resettled from other villages or were returning to family lands. Attitudes toward PAs were generally positive, but immigrants attracted by the area and who used resources within the PA with fewer restrictions expressed more negative attitudes toward PAs. Household location, losses due to wild animals, and restrictions on access to natural resources were the main drivers of this negative attitude. Profit-seeking migrants did not expect these constraints and were particularly concerned with local overpopulation and access to natural resources. To avoid socio-ecological traps near PAs (i.e., unforeseen reduced adaptive capacity) integrated conservation should address mismatches between management policy and local expectations. This requires accounting for endogenous processes, for example, local socio-ecological dynamics and values that shape the coexistence between humans and wildlife. © 2013 Society for Conservation Biology.

    Einschläge (Impakte) von Asteroiden und Kometen größer 1 km im Durchmesser sind seltene Ereignisse, jedoch mit katastrophalen Folgen für die gesamte irdische Biosphäre. Auch kleinere erdnahe Objekte (NEOs - Near-Earth Objects) können beträchtliche direkte und sekundäre Schäden anrichten. Um solche Impakte zu vermeiden, ist es notwendig, einerseits eine Beobachtungsinfrastruktur zu entwickeln, um alle relevanten NEOs zu entdecken und mit den extrapolierten Bahnparametern eine mögliche Kollision mit der Erde vorherzusagen. Mittels eines Abwehrsystems müßte man dann den NEO auf eine ungefährliche Bahn lenken. In allen Phasen, d.h. von der Suche nach NEOs, über Planung, Test und Einsatz des Abwehrsystems, können oder müssen Satellitensysteme unterschiedlicher Art eingesetzt werden. Konzepte dieser Systeme werden in dieser Arbeit vorgestellt und die mit ihnen verbundenen Probleme diskutiert.

Given the abundance of this compound, its utilization in synthetic chemistry, particularly on an industrial scale, is still at a rather low level. In the last 35 years, considerable research has been performed to find catalytic routes to transform CO2 into carboxylic acids, esters, lactones, and polymers in an economic way. This Review presents an overview of the available homogeneous catalytic routes that use carbon dioxide as a C1 carbon source for the synthesis of industrial products as well as fine chemicals.

    The dielectric loss of sixteen molecules, eleven with the acetyle group in aromatic bonds and five in aliphatic bonds, has been measured in very dilute solutions of cyclohexene at 20 °C. Five of these molecules are investigated in decalene solutions, too. The measurements have been made at wavenumbers in the range 0.08 to 140 cm -1 above 8 cm -1 making use of a pumped molecular laser. They are supplemented by the data of a Fourier transform spectrometer up to 300 cm -1. All microwave spectra of loss factor ɛ″ are analysed in terms of three absorption areas using the two variable Mori formalism. On the other hand, Lorentz curves are fitted to the FIR absorption spectra of α(v¯). The fast relaxation process of the aliphatic compounds is suggested to be due to intramolecular reorientation of the acetyle group itself, since in acetyle cyclohexene the remaining part of the molecule is rigid. To the contrary, the acetyle group is not able to reorientate swiftly, if bounded to aromatic rings. Presumably, it is fixed by mesomeric interaction with the dipole in the plain of the ring. However, 2-methyl acetophenone and 1-acetyle naphthone show some quick dipole reorientation, which coincides with a steric hindrance of the group in entering the plain of the ring.

Thus, the aim of this study was to compare the detailed in vivo toxicity of Cu NPs and cupric ions (CuCl2; Cu ions after a single oral dose. We determined the physicochemical characteristics of Cu NPs, including morphology, hydrodynamic size, zeta potential, and dissolution in gastric (pH 1.5, vehicle (pH 6.5, and intestinal (pH 7.8 conditions. We also evaluated the kinetics of Cu following a single equivalent dose (500 mg/kg of Cu NPs and Cu ions. Cu NPs had highest dissolution (84.5% only in gastric conditions when compared with complete dissolution of Cu ions under various physiological milieus. Kinetic analysis revealed that highest Cu levels in blood and tested organs of Cu NP-treated rats were 15%–25% lower than that of Cu ions. Similar to the case of Cu ions, Cu levels in the tested organs (especially liver, kidney, and spleen of Cu NP-treated rats increased significantly when compared with the vehicle control. However, delay in reaching the highest level and biopersistence of Cu were observed in the blood and tested organs of Cu NP-treated rats compared with Cu ions. Extremely high levels of Cu in feces indicated that unabsorbed Cu NPs or absorbed Cu ions were predominantly eliminated through liver/feces. Cu NPs exerted apparent toxicological effects at higher dose levels compared with Cu ions and showed sex-dependent differences in mortality, biochemistry, and

The program alerted the worker if books found had an active status (i.e., Missing, Renewed, Overdue, Charged, were not in the correct order, or were not in the system. Each transaction created a log which contained a time stamp (to the second, the call number and the barcode number. It also took note of scanning errors, books that were out of order, and books that were not on a shelf-list. After a complete section was examined, a list was produced to reveal the distance of mis-shelved books from their correct location and the amount of time between each scan. The researchers used statistical analysis (using SPSS 15.0 to measure scan speed for each scan, mis-shelving rate and error distance of each mis-shelved book. In order to analyze the cost of labour to replace a book versus the cost of inventorying, the researchers estimated the salary costs of staff members involved in selection, acquisition and cataloguing. The library spent $440,000 USD in labour costs to purchase 15,000 monographs in one fiscal year (approximately $30.00 USD in labour costs per book. They multiplied this by 5300 books that were found to be “badly” mis-shelved (found beyond 25 books away from the proper position. Labour fees were used to determine costs of inventorying by calculating average scanning speed and cost per hour to pay someone to scan the entire half-million monograph collection.Main Results – It took approximately 707 hours to scan 305,000 monographs. The average (mode calculation for scans was 5 seconds for 80% of the barcodes, with an average (mean of 8.35 seconds between scans. The longest average (mean time for scanning barcodes was in the N section, followed by G, H, P, Q, D, E and F. A total of 291 books were found on the shelves with an “active” status (i.e., Charged (4, Overdue (7, Renewed (4, In Transit (24, and Missing (228. Twenty-four books with the status “Miscellaneous” (i.e., At Bindery, Call Slip, Cataloguing Review, Damaged, and Mending were also found on the shelves. Of the 15 active books in the categories “Charged”, “Overdue” and “Renewed”, ten were found in the proper position on the shelf. Of the 228 “Missing” books, 30% were scanned in the correct location, 10% were found 26 to 100 books away, and half were located over 100 books from their proper location. In addition to the books already marked as “Missing” in the catalogue, there were 516 books (.17% of the entire scanned section still not found on the shelf after three searches over a period of 6 months. Of the 291 active status books found on the shelves, 52% were reused as of July 2008. (The inventory was completed at the end of 2006. Over 36% of books mis-shelved further than 25 books from their correct location were reused. However, among all books scanned, only 17% were reused during the same time period. The researchers noted that inconsistencies between the call number as shown on the book label and how it appeared in the catalogue occurred 565 times. Of these discrepancies, 40% of the labels resulted in books being misplaced ten or fewer books away, 10% misplaced between 10 and 100 books away, and 35% misplaced more than 100 books away from the correct position. In general, 82% of mis-shelved books were found within 1 to 25 books away from their correct location. By calculating that 5300 books were mis-shelved beyond 25 books away from their proper position, labour costs were estimated to be at least $159,000 USD (5300 x $30.00 USD per book in labour costs. Costs for interlibrary loan were calculated at approximately $30.00 USD per transaction, and patron’s time wasted trying to locate misplaced books was estimated at 30 minutes per book. This was much more than the labour costs associated with scanning books, which at an average speed of 8 seconds per book and $10.00 US per hour for scanning worked out to be 2.2 cents per book, or $11,000 USD to scan the entire half-million monograph collection.Conclusion – The results appear to reveal that the labour costs for inventory control are less expensive than repurchasing or borrowing the same number of books.

Among them, pH-responsive drug targeting using pH-sensitive polymers has attracted attention because solid tumors have an acidic environment. A dextran-b-poly(L-histidine (DexPHS copolymer was synthesized and pH-responsive nanoparticles were fabricated for drug targeting. Methods and results: A DexPHS block copolymer was synthesized by attaching the reductive end of dextran to the amine groups of poly(L-histidine. pH-responsive nanoparticles incorporating doxorubicin were fabricated and studied in HuCC-T1 cholangiocarcinoma cells. Synthesis of DexPHS was confirmed by 1H nuclear magnetic resonance spectroscopy, with specific peaks of dextran and PHS observed at 2–5 ppm and 7.4–9.0 ppm, respectively. DexPHS nanoparticles showed changes in particle size with pH sensitivity, ie, the size of the nanoparticles increased at an acidic pH and decreased at a basic pH. DexPHS block copolymer nanoparticles incorporating doxorubicin were prepared using the nanoprecipitation dialysis method. The doxorubicin release rate was increased at acidic pH compared with basic pH, indicating that DexPHS nanoparticles have pH-sensitive properties and that drug release can be controlled by variations in pH. The antitumor activity of DexPHS nanoparticles incorporating doxorubicin were studied using HuCC-T1

We fixed suicide attempt as the dependent variable and eleven sociodemographic, intrapersonal, and extrapersonal variables as independent variables.Results: The rate of suicide attempts of the total sample was 9.5%, and severity of depression was the strongest variable to predict suicide attempt. The rates of suicide attempts in the depression and potential depression groups were 5.4 and 2.8 times higher than that of the non-depression group. In the depression group, the most powerful factor to predict a suicide attempt was delinquency, and the rate of suicide attempts in those in the depression group with higher delinquency was two times higher than in those in the depression group with lower delinquency. Of special note, the rate of suicide attempts in the depressed females with higher delinquency was the highest. Interestingly, in the potential depression group, the most impactful factor to predict a suicide attempt was intimacy with family, and the rate of suicide attempts of those in the potential depression group with lower intimacy with family was 2.4 times higher than that of those in the potential depression group with higher intimacy with family. And, among the potential depression group, middle school students with lower intimacy with family had a 2.5-times higher rate of suicide attempts than high school students with lower intimacy with family.

Second, using the SAS process, solid dispersions of sirolimus-polyvinylpyrrolidone (PVP K30 nanoparticles were prepared with or without surfactants such as sodium lauryl sulfate (SLS, tocopheryl propylene glycol succinate, Sucroester 15, Gelucire 50/13, and Myrj 52. A mean particle size of approximately 250 nm was obtained for PVP K30-sirolimus nanoparticles. Solid state characterization, kinetic solubility, powder dissolution, stability, and pharmacokinetics were analyzed in rats.Results: X-ray diffraction, differential scanning calorimetry, and high-pressure liquid chromatography indicated that sirolimus existed in an anhydrous amorphous form within a solid dispersion of nanoparticles and that no degradation occurred after SAS processing. The improved supersaturation and dissolution of sirolimus as a solid dispersion of nanoparticles appeared to be well correlated with enhanced bioavailability of oral sirolimus in rats. With oral administration of a solid dispersion of PVP K30-SLS-sirolimus nanoparticles, the peak concentration and AUC0→12h of sirolimus were increased by approximately 18.3-fold and 15.2-fold, respectively.Conclusion: The results of this study suggest that preparation of PVP K30-sirolimus-surfactant nanoparticles using the SAS process may be a promising approach for improving the bioavailability of sirolimus

    We investigated the production of sung and spoken utterances in a non-fluent patient, C.C., who had a severe expressive aphasia following a right-hemisphere stroke, but whose language comprehension and memory were relatively preserved. In experiment 1, C.C. repeated familiar song excerpts under four different conditions: spoken lyrics, sung lyrics on original melody, lyrics sung on new but familiar melody and melody sung to a neutral syllable "la". In experiment 2, C.C. repeated novel song excerpts under three different conditions: spoken lyrics, sung lyrics and sung-to-la melody. The mean number of words produced under the spoken and sung conditions did not differ significantly in either experiment. The mean number of notes produced was not different either in the sung-to-la and sung conditions, but was higher than the words produced, hence showing a dissociation between C.C.'s musical and verbal productions. Therefore, our findings do not support the claim that singing helps word production in non-fluent aphasic patients. Rather, they are consistent with the idea that verbal production, be it sung or spoken, result from the operation of same mechanisms.

For comparison, fenofibrate-loaded Neusilin UFL2 was prepared by solvent evaporation and hot melt-adsorption methods. The fenofibrate formulations prepared were characterized by differential scanning calorimetry, powder x-ray diffractometry, specific surface area, pore size distribution, scanning electron microscopy, and energy-dispersive x-ray spectrometry. In vitro dissolution and in vivo bioavailability were also investigated.Results: Fenofibrate was distributed into the pores of Neusilin UFL2 and showed reduced crystal formation following adsorption. Supercritical CO2 facilitated the introduction of fenofibrate into the pores of Neusilin UFL2. Compared with raw fenofibrate, fenofibrate from the prepared powders showed a significantly increased dissolution rate and better bioavailability. In particular, the area under the drug concentration-time curve and maximal serum concentration of the powders prepared using supercritical CO2 were 4.62-fold and 4.52-fold greater than the corresponding values for raw fenofibrate.Conclusion: The results of this study highlight the usefulness of the melt-adsorption method using supercritical CO2 for improving the bioavailability of fenofibrate.Keywords: fenofibrate

Materials and methods: The isotopes [14C] and [59Fe] were used to label the polymer backbone (CLS and iron oxide core (FLS, respectively. In addition, unradiolabeled cold superparamagnetic iron oxide nanoparticles (SPION/ULS were synthesized to characterize particle size by dynamic light scattering, morphology by transmission electron microscopy, and in vivo magnetic resonance imaging (MRI. CLS and FLS were used separately to investigate the behavior of both the synthesized polymer and [Fe] in Sprague Dawley (SD rats, respectively. Because radioactivity of the isotopes was different by β for CLS and γ for FLS, synthesis of the samples had to be separately prepared. Results: The mean particle size of the ULS was 66.1 nm, and the biodistribution of CLS concentrations in various organs, in rank order of magnitude, was liver > kidney > small intestine > other. The biodistribution of FLS concentrations was liver > spleen > lung > other. These rank orders show that synthesized SPION mainly accumulates in the liver. The differences in the distribution were caused by the SPION metabolism. Radiolabeled

The archives of solar integral exposures and of spectroheliograms of the former Fraunhofer Institute (now: Kiepenheuer Institute for Solar Physics) in Freiburg and its partial dissolution (German Title: Die Archive solarer Integralaufnahmen und von Spektroheliogrammen des früheren Fraunhofer-Instituts (jetzt: Kiepenheuer-Institut für Sonnenphysik) in Freiburg und ihre teilweise Auflösung)

    Science.gov (United States)

    Wöhl, Hubertus

    The former Fraunhofer-Institut which was founded about 60 years ago and since 1978 is named Kiepenheuer-Institut für Sonnenphysik (KIS), has been for several decades a center to collect information about solar activity. One of the reasons for interest in solar activity were in the beginning attempts to forecast disturbances of (military) radio communication caused by solar eruptions. This would today be called ‘space weather research’. Later daily maps of the sun - showing its activity - were edited for many years. The data needed to describe solar activity were gained mainly from photographic images: Since 1939 white light images of the full solar disk were collected and stored in the archive. Since 1943 in addition spectroheliograms of the full solar disk in H-alpha and in Ca II K3 were collected. These images were taken on glass plates (some on film) of sizes 9 x 12 cm in the case of the white light images and of sizes 6 x 12 cm in the case of the spectroheliograms and were stored in envelopes with additional information written on them. Several hundred of these plates in their envelopes were combined in open wooden boxes each. These boxes were stored in open shelfs in a meeting room of the old solar observatory on the Schauinsland mountain near Freiburg. Within the last years it became obvious that the quality of many plates stored was bad and that the possible scientific usage was becoming very limited. In summer 2002 I started to investigate the quality of the white light images and prepared a data base in MS ACCESS XP about the plates I found which were observed at more than 10 different observing places. The total number of plates checked was 11782. Depending on the quality and possible later usage for an investigation of proper motions in sunspot groups I kept several series of them. Most of the plates kept stem from the years 1945 until 1949 and 1955 until 1959 - when the solar activity was extremely high. In total about 2000 plates were kept. It is intended to digitize as many as possible of these selected plates using a high precision scanner for transparencies. Some examples of digitized images are already available. More details can be found in a text about the history of the Fraunhofer-Institut in the WWW pages of the KIS at: http://www.kis.uni-freiburg.de/kisgeschichte_e.html In summer 2003 I started to investigate the quality of the spectroheliograms on glass plates and to prepare another data base of the material I find in the archive.

    本文主要是为了研究韩国与中国的大学生使用社交媒体( Social Media)的动机,以及与广告使用动机进行比较并找出其差异.为此本文采用媒体的使用与满足理论(use and gratification theory),找出使用社交媒体的动机,并分析了这些动机对社交媒体广告的使用意向起到何种影响.分析结果显示,第一、韩国与中国的大学生使用社交媒体都是出于实用性动机;第二、在两国使用社交媒体的动机来看,韩国只有在使用值得信赖的广告方面起到积极影响,而中国在信息的可信赖度、转换心情、个人实用性等使用广告的三个动机上都起到了影响.本文的研究结果表明,在使用社交媒体广告时,韩国消费者的“使用网络信息与内容”、“网络搜索”、“追求娱乐”等使用动机起到了积极效果,而社交媒体广告的可信赖度得到满足最为重要;而中国消费者的“网络搜索”对使用“值得信赖的”广告的动机时起到了积极影响,“社会联系”、“在意别人对自己的评价”等选项则是为了“转换心情”使用广告起到了积极影响,另外“社会联系”还对“个人实用性”广告使用动机起到了影响.

    2000-07-01

    The present research addresses whether music training acts as a mediator of the recall of spoken and sung lyrics and whether presentation rate is the essential variable, rather than the inclusion of melody. In Experiment 1, 78 undergraduates, half with music training and half without, heard spoken or sung lyrics. Recall for sung lyrics was superior to that for spoken lyrics for both groups. In Experiments 2 and 3, presentation rate was manipulated so that the durations of the spoken and the sung materials were equal. With presentation rate equated, there was no advantage for sung over spoken lyrics. In all the experiments, those participants with music training outperformed those without training in all the conditions. The results suggest that music training leads to enhanced memory for verbal material. Previous findings of melody's aiding text recall may be attributed to presentation rate.

  20. Mapping the entangled ontology of science teachers' lived experience

    Science.gov (United States)

    Daugbjerg, Peer S.; de Freitas, Elizabeth; Valero, Paola

    2015-09-01

    In this paper we investigate how the bodily activity of teaching, along with the embodied aspect of lived experience, relates to science teachers' ways of dealing with bodies as living organisms which are both the subject matter as well as the site or vehicle of learning. More precisely, the following questions are pursued: (1) In what ways do primary science teachers refer to the lived and living body in teaching and learning? (2) In what ways do primary science teachers tap into past experiences in which the body figured prominently in order to teach students about living organisms? We draw on the relational ontology and intra-action of Karen Barad (J Women Cult Soc 28(3): 801, 2003) as she argues for a "relational ontology" that sees a relation as a dynamic flowing entanglement of a matter and meaning. We combine this with the materialist phenomenological studies of embodiment by SungWon Hwang and Wolff-Michael Roth (Scientific and mathematical bodies, Sense Publishers, Rotterdam, 2011), as they address how the teachers and students are present in the classroom with/in their "living and lived bodies". Our aim is to use theoretical insights from these two different but complementary approaches to map the embodiment of teachers' experiences and actions. We build our understanding of experience on the work of John Dewey (Experience and education, Simon & Schuster, New York, 1938) and also Jean Clandinin and Michael Connelly (Handbook of qualitative research, Sage Publications, California, 2000), leading us to propose three dimensions: settings, relations and continuity. This means that bodies and settings are mutually entailed in the present relation, and furthermore that the past as well as the present of these bodies and settings—their continuity—is also part of the present relation. We analyse the entanglement of lived experience and embodied teaching using these three proposed dimensions of experience. Analysing interviews and observations of three Danish

In a real-world setting, the majority of patients with COPD have mild-to-moderate airflow limitation. Therefore, it is important to evaluate COPD exacerbation in patients with mild-to-moderate airflow limitation, although most studies have focused on the patients with moderate or severe COPD. The objective of this study was to evaluate factors associated with COPD exacerbation in patients with mild-to-moderate airflow limitation. Methods: Patients registered in the Korean COPD Subtype Study cohort were recruited from 37 tertiary referral hospitals in Korea. We obtained their clinical data including demographic characteristics, past medical history, and comorbidities from medical records. Patients were required to visit the hospital to document their COPD status using self

    Full Text Available Authenticated key exchange protocols are of fundamental importance in securing communications and are now extensively deployed for use in various real-world network applications. In this work, we reveal major previously unpublished security vulnerabilities in the password-based authenticated three-party key exchange protocol according to Lee and Hwang (2010: (1 the Lee-Hwang protocol is susceptible to a man-in-the-middle attack and thus fails to achieve implicit key authentication; (2 the protocol cannot protect clients’ passwords against an offline dictionary attack; and (3 the indistinguishability-based security of the protocol can be easily broken even in the presence of a passive adversary. We also propose an improved password-based authenticated three-party key exchange protocol that addresses the security vulnerabilities identified in the Lee-Hwang protocol.

    2017-02-01

    The efficacy of using sung words as a mnemonic device for verbal memory has been documented in persons with probable Alzheimer's dementia (AD), but it is not yet known whether this effect is related to music training. Given that music training can enhance cognitive functioning, we explored the effects of music training and modality (sung vs. spoken) on verbal memory in persons with and without AD. We used a mixed factorial design to compare learning (5 trials), delayed recall (30-min and, 24-hour), and recognition of sung versus spoken information in 22 healthy elderly (15 musicians), and 11 people with AD (5 musicians). Musicians with AD showed better total learning (over 5 trials) of sung information than nonmusicians with AD. There were no significant differences in delayed recall and recognition accuracy (of either modality) between musicians with and without AD, suggesting that music training may facilitate memory function in AD. Analysis of individual performances showed that two of the five musicians with AD were able to recall some information on delayed recall, whereas the nonmusicians with AD recalled no information on delay. The only significant finding in regard to modality (sung vs. spoken) was that total learning was significantly worse for sung than spoken information for nonmusicians with AD. This may be due to the need to recode information presented in song into spoken recall, which may be more cognitively demanding for this group. This is the first study to demonstrate that music training modulates memory of sung and spoken information in AD. The mechanism underlying these results is unclear, but may be due to music training, higher cognitive abilities, or both. Our findings highlight the need for further research into the potentially protective effect of music training on cognitive abilities in our aging population.

  3. For 5-Month-Old Infants, Melodies Are Social.

    For 1 to 2 weeks, 5-month-old infants listened at home to one of two novel songs with identical lyrics and rhythms, but different melodies; the song was sung by a parent, emanated from a toy, or was sung live by a friendly but unfamiliar adult first in person and subsequently via interactive video. We then tested the infants' selective attention to two novel individuals after one sang the familiar song and the other sang the unfamiliar song. Infants who had experienced a parent singing looked longer at the new person who had sung the familiar melody than at the new person who had sung the unfamiliar melody, and the amount of song exposure at home predicted the size of that preference. Neither effect was observed, however, among infants who had heard the song emanating from a toy or being sung by a socially unrelated person, despite these infants' remarkable memory for the familiar melody, tested an average of more than 8 months later. These findings suggest that melodies produced live and experienced at home by known social partners carry social meaning for infants. © The Author(s) 2016.

  6. Beyond Authoritarian Personality: The Culture-Inclusive Theory of Chinese Authoritarian Orientation.

    Science.gov (United States)

    Chien, Chin-Lung

    2016-01-01

    In a dyad interaction, respecting and obeying those with high status (authority) is highly valued in Chinese societies. Regarding explicit behaviors, Chinese people usually show respect to and obey authority, which we call authoritarian orientation. Previous literature has indicated that Chinese people have a high degree of authoritarian personality, which was considered a national character. However, under Confucian relationalism (Hwang, 2012a), authoritarian orientation is basically an ethical issue, and thus, should not be reduced to the contention of authoritarian personality. Based on Yang's (1993) indigenous conceptualization, Chien (2013) took an emic bottom-up approach to construct an indigenous model of Chinese authoritarian orientation; it represents a "culture-inclusive theory." However, Chien's model lacks the role of agency or intentionality. To resolve this issue and to achieve the epistemological goal of indigenous psychology (that is, "one mind, many mentalities"), this paper took the "cultural system approach" (Hwang, 2015b) to construct a culture-inclusive theory of authoritarian orientation in order to represent the universal mind of human beings as well as the mentalities of people in a particular culture. Two theories that reflect the universal mind, the "Face and Favor model" (Hwang, 1987) and the "Mandala Model of Self" (Hwang, 2011a,c), were used as analytical frameworks for interpreting Chien's original model. The process of constructing the culture-inclusive theory of authoritarian orientation may represent a paradigm for the construction of indigenous culture-inclusive theories while inspiring further development. Some future research directions are proposed herein.

    Telomeric DNA binds proteins to protect chromosome ends, but it also adopts G quadruplex (GQ) structures. Two new studies by Hwang and colleagues (in this issue of Structure) and Ray and colleagues (published elsewhere) use single molecule imaging to reveal how GQs affect the binding of different telomere associated proteins. The data suggest that GQs play important roles in regulating accessibility of telomeres.

  10. Transitions and Time: Dissonance between Social and Political Aging in South Korea

    Directory of Open Access Journals (Sweden)

    Won Jee Cho

    2012-05-01

    Full Text Available This study explored multidimensional meanings related to “becoming old” for the young-old in South Korean society. Six persons aged 62 to 68 were interviewed in-depth. They chronologically, physically, and socially experienced the transition to old age at different times determined through “Hwan-Gap” (at age 60 and through current social policies that define entry into elderhood (at age 65. However, most did not psychologically accept their own aging as beginning at age 60 with “Hwan-Gap.” They reported that they were “forced” to become old at that time, even though they did not yet qualify for old age benefits provided by the South Korean government. In addition, they did not consider others’ perceptions of them as “old” as a psychological obstacle to defining themselves as young. Knowledge about young-old persons’ dissonance between their identities and sociopolitical views of entry into elderhood is important for understanding their experiences during the five-year gap between sociocultural entry into old age at age 60 and entry into the nationally defined elderhood at age 65.

  11. Melanite garnet-bearing nepheline syenite minor intrusion in Mawpyut ultramafic–mafic complex, Jaintia Hills, Meghalaya

    Indian Academy of Sciences (India)

    2011-12-01

    Mawpyut igneous suite in Jaintia Hills of Meghalaya plateau comprises differentiated suite of ultramafic–mafic rocks. The complex differs from other ultramafic–alkaline–carbonatite igneous emplacements of Shillong plateau and Mikir Hills like Jesra, Sung, Samchampi complexes, by the absence of alkaline–carbonatite rocks as major litho-units. Melanite garnet-bearing nepheline syenite, occurs as late phase minor intrusion in Mawpyut igneous complex, posseses alkaline character and shows inubiquitous relation with the host ultramafic–mafic rocks. On the other hand, this alkaline intrusive bodies of the Mawpyut igneous complex shows chemico-mineralogical resemblance with garnet-bearing nepheline syenite, ijolite litho-members of Jesra, Sung, Samchampi complexes of the region. It is interpreted that melanite garnet-bearing nepheline syenite intrusion in Mawpyut is contemporaneous with Jesra, Sung, Samchampi ultramafic–alkaline–carbonatite complexes and the host rocks of Mawpyut complex is an earlier magmatic activity possibly from a comparatively least enriched source.

    Eleven infants with Down's syndrome and 10 of 11 nonhandicapped infants operated an automatic device which enabled them to choose to listen to nursery rhymes sung or played on musical instruments. Both groups preferred the singing, and the Down's Syndrome infants had much longer response durations for the more complex auditory stimuli. (Author/DB)

  17. Word Intelligibility in Multi-voice Singing: The Influence of Chorus Size.

    Science.gov (United States)

    Condit-Schultz, Nathaniel; Huron, David

    2017-01-01

    This study investigated how the intelligibility of sung words is influenced by the number of singers in a choral music style. The study used repeated measures factorial. One hundred forty-nine participants listened to recordings of spoken and sung English words and attempted to identify the words. Each stimuli word was sung or spoken in sync by either one, four, eight, sixteen, or twenty-seven members of a high-quality Soprano Alto Tenor Bass (SATB) choir. In general, single-voice word recognition was higher than multi-voice word recognition in the sung condition. However, the difference between four concurrent singers and the full choir was negligible; that is, reduced intelligibility with multiple singers shows little sensitivity to the number of singers. The principal effect of voice density on intelligibility is found to occur with coda consonants-a result consistent with the importance many choral conductors attribute to coordinating word offsets. In particular, the plosives /b/, /d/, /g/, and /p/ are easily confused. Coda liquids (/l/,/r/) were also found to be a source of confusion. Finally, an increasing density of voices appears to have a facilitating effect for the coda nasal /m/. Groups of four or more choral singers do appear to be less intelligible than single singers, although the observed effect is modest. However, increasing the number of singers in a choral texture beyond four singers does not appear to further degrade intelligibility. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

  20. The impact of music on learning and consolidation of novel words.

    2017-01-01

    Music can be a powerful mnemonic device, as shown by a body of literature demonstrating that listening to text sung to a familiar melody results in better memory for the words compared to conditions where they are spoken. Furthermore, patients with a range of memory impairments appear to be able to form new declarative memories when they are encoded in the form of lyrics in a song, while unable to remember similar materials after hearing them in the spoken modality. Whether music facilitates the acquisition of completely new information, such as new vocabulary, remains unknown. Here we report three experiments in which adult participants learned novel words in the spoken or sung modality. While we found no benefit of musical presentation on free recall or recognition memory of novel words, novel words learned in the sung modality were more strongly integrated in the mental lexicon compared to words learned in the spoken modality. This advantage for the sung words was only present when the training melody was familiar. The impact of musical presentation on learning therefore appears to extend beyond episodic memory and can be reflected in the emergence and properties of new lexical representations.

  15. Cryptanalysis And Further Improvement Of A Biometric-Based Remote User Authentication Scheme Using Smart Cards

    CERN Document Server

    Das, Ashok Kumar

    2011-01-01

    Recently, Li et al. proposed a secure biometric-based remote user authentication scheme using smart cards to withstand the security flaws of Li-Hwang's efficient biometric-based remote user authentication scheme using smart cards. Li et al.'s scheme is based on biometrics verification, smart card and one-way hash function, and it also uses the random nonce rather than a synchronized clock, and thus it is efficient in computational cost and more secure than Li-Hwang's scheme. Unfortunately, in this paper we show that Li et al.'s scheme still has some security weaknesses in their design. In order to withstand those weaknesses in their scheme, we further propose an improvement of their scheme so that the improved scheme always provides proper authentication and as a result, it establishes a session key between the user and the server at the end of successful user authentication.

  16. Cosmology and stellar equilibrium using Newtonian hydrodynamics with general relativistic pressure

    2015-01-01

    We revisit the analysis made by Hwang and Noh [JCAP 1310 (2013)] aiming the construction of a Newtonian set of equations incorporating pressure effects typical of General Relativity theory. We perform in an explicit way the deduction of the Hwang-Noh equations, comparing it with similar computations found in the literature. Later, we investigate stellar equilibrium and cosmology, at background and perturbative levels, using the new set of equations. It is shown that, in this context, the predictions for the background evolution of the universe are deeply changed with respect to the full relativistic theory: the acceleration of the universe is achieved with positive pressure. The properties of neutron stars are reproduced qualitatively, but the upper mass is at least one order of magnitude higher than that obtained in General Relativity. However, the perturbed cosmological equations at small scales reproduce those found in the relativistic context. We argue that this last result may open new possibilities for ...

    2012-12-01

    In a previous study (Simmons-Stern, Budson & Ally, 2010), we found that patients with Alzheimer's disease (AD) better recognized visually presented lyrics when the lyrics were also sung rather than spoken at encoding. The present study sought to further investigate the effects of music on memory in patients with AD by making the content of the song lyrics relevant for the daily life of an older adult and by examining how musical encoding alters several different aspects of episodic memory. Patients with AD and healthy older adults studied visually presented novel song lyrics related to instrumental activities of daily living (IADL) that were accompanied by either a sung or a spoken recording. Overall, participants performed better on a memory test of general lyric content for lyrics that were studied sung as compared to spoken. However, on a memory test of specific lyric content, participants performed equally well for sung and spoken lyrics. We interpret these results in terms of a dual-process model of recognition memory such that the general content questions represent a familiarity-based representation that is preferentially sensitive to enhancement via music, while the specific content questions represent a recollection-based representation unaided by musical encoding. Additionally, in a test of basic recognition memory for the audio stimuli, patients with AD demonstrated equal discrimination for sung and spoken stimuli. We propose that the perceptual distinctiveness of musical stimuli enhanced metamemorial awareness in AD patients via a non-selective distinctiveness heuristic, thereby reducing false recognition while at the same time reducing true recognition and eliminating the mnemonic benefit of music. These results are discussed in the context of potential music-based memory enhancement interventions for the care of patients with AD.

    Full Text Available One of the main objectives of Heterogeneous Wireless Access Networks (HWAN is to integrate the different wireless access technologies, such as Universal Mobile Telecommunication System (UMTS, Worldwide Interoperability for Microwave Access (WiMAX and Wireless Local Area Network (WLAN, with a common IP-based network in order to offer mobile users continuous and unified service in a transparent way. However, one of the major issues is to support end-to-end Quality of Service (QoS across all these technologies at all stages of the service from set-up to handoff. We present, in this study, a novel method of mapping QoS of UMTS and WiMAX over a loose coupling environment across Internet Protocol/Differentiated Service (IP/DiffServ network.

    Scientific misconduct and fraud occur in science. The (anonymous) peer review process serves as goalkeeper of scientific quality rather than scientific integrity. In this brief paper we describe some limitations of the peer-review process. We describe the catastrophic facts of the 'Woo-Suk Hwang fraud case' and raise some ethical concerns about the issue. Finally, we pay attention to plagiarism, autoplagiarism and double publications. (Neth Heart J 2009;17:25-9.).

  9. Beyond Authoritarian Personality: The Culture-Inclusive Theory of Chinese Authoritarian Orientation

    Science.gov (United States)

    Chien, Chin-Lung

    2016-01-01

    In a dyad interaction, respecting and obeying those with high status (authority) is highly valued in Chinese societies. Regarding explicit behaviors, Chinese people usually show respect to and obey authority, which we call authoritarian orientation. Previous literature has indicated that Chinese people have a high degree of authoritarian personality, which was considered a national character. However, under Confucian relationalism (Hwang, 2012a), authoritarian orientation is basically an ethical issue, and thus, should not be reduced to the contention of authoritarian personality. Based on Yang's (1993) indigenous conceptualization, Chien (2013) took an emic bottom-up approach to construct an indigenous model of Chinese authoritarian orientation; it represents a “culture-inclusive theory.” However, Chien's model lacks the role of agency or intentionality. To resolve this issue and to achieve the epistemological goal of indigenous psychology (that is, “one mind, many mentalities”), this paper took the “cultural system approach” (Hwang, 2015b) to construct a culture-inclusive theory of authoritarian orientation in order to represent the universal mind of human beings as well as the mentalities of people in a particular culture. Two theories that reflect the universal mind, the “Face and Favor model” (Hwang, 1987) and the “Mandala Model of Self” (Hwang, 2011a,c), were used as analytical frameworks for interpreting Chien's original model. The process of constructing the culture-inclusive theory of authoritarian orientation may represent a paradigm for the construction of indigenous culture-inclusive theories while inspiring further development. Some future research directions are proposed herein. PMID:27445894

    Wen Fengtong; Li Xuelei; Cui Shenjun

    2011-01-01

    In 2010,Hwang,et al.proposed a 'DoS-resistant ID-based password authentication scheme using smart cards' as an improvement of Kim-Lee-Yoo's ‘ID-based password authentication scheme'.In this paper,we cryptanalyze Hwang,et al.'s scheme and point out that the revealed session key could threat the security of the scheme.We demonstrate that extracting information from smart cards is equal to knowing the session key.Thus known session key attacks are also effective under the assumption that the adversary could obtain the information stored in the smart cards.We proposed an improved scheme with security analysis to remedy the weaknesses of Hwang,et al.'s scheme.The new scheme does not only keep all the merits of the original,but also provides several additional phases to improve the flexibility.Finally,the improved scheme is more secure,efficient,practical,and convenient,because elliptic curve cryptosystem is introduced,the expensive smart cards and synchronized clock system are replaced by mobile devices and nonces.

  12. Trojan Horse Attack Free Fault-Tolerant Quantum Key Distribution Protocols Using GHZ States

    2016-09-01

    Recently, Yang and Hwang (Quantum Inf. Process. 13(3): 781-794, 19) proposed two fault-tolerant QKD protocols based on their proposed coding functions for resisting the collective noise, and their QKD protocols are free from Trojan horse attack without employing any specific detecting devices (e.g., photon number splitter (PNS) and wavelength filter). By using four-particle Greenberger-Horne-Zeilinger (GHZ) state and four-particle GHZ-like state in their proposed coding functions, Yang and Hwang's QKD protocols can resist each kind of the collective noise-collective-dephasing noise, collective-rotation noise. However, their proposed coding function can be improved by the utilization of three-particle GHZ state (three-particle GHZ-like state) instead of four-particle GHZ state (four-particle GHZ-like state) that will eventually reduce the consumption of the qubits. As a result, this study proposed the improved version of Yang and Hwang's coding functions to enhance the qubit efficiency of their schemes from 20 % to 22 %.

    Full Text Available THE COMPARISON OF THE QUALITY OF SPOKEN AND SUNG LATVIAN VOWELS [i:], [ɑ:] AND [u:]SummaryNumerous studies in phonetics have attempted to investigate the differences between spoken and sung vowels. The majority of these studies dealt with the articulatory and acoustic changes observed in opera singers, however, there were several studies which compared the production of vowels by opera and choir singers. This article presents a pilot study performed on the basis of an audio material acquired from one informant (mezzo-soprano, where the acoustic quality of spoken Latvian vowels [i:], [ɑ:] and [u:] has been compared to the quality of the same vowels sung in isolation (in octave of La Minor, i.e., from A3 to A4, labeled in this article as octave of Do Major because of cer­tain reasons and sung in the verse of a song. It was observed during the current study that the transition from the chest register to the middle register had taken place between C4 and D4, which is normally observed in mezzo-sopranos. To make the interpretation of the influence of a variable pitch on the vowel formant pattern easier, all Latvian vowels were plotted in the psycho-physical F2ʹ/F1 (bark plane. The observed changes in F1 re­flect the tuning of the first vocal resonance to the pitch that is acquired by a jaw opening. Gradual larynx lowering and lip rounding can be the reason for lowering of F2ʹ value for [i:], reduced lip rounding — for increasing of F2ʹ value for [u:], but rising of the tongue tip — for increasing of F2ʹ value for [ɑ:]. The observed changes question the assumption that vowels in singing preserve their quality except for very low and very high registers (the octave under investigation does not belong to such registers. The minor differences observed in vowels sung in the verse from vowels sung in isolation can be explained by the influence of immediate phonetic context. It can be concluded that the data obtained in this investigation, in

    Full Text Available Einleitung: Eine häufige Komplikation der transurethralen oder suprapubischen Dauerkatheterversorgung ist die Dislokation durch eine insuffiziente Katheterblockung. Die Auswirkungen des Urin-pH auf das Ballonvolumen sind dabei bisher nicht untersucht. Methodik: In einer In-vitro-Studie wurden Dauerkatheter aus Silikon und Latex mit entweder 10%iger Glyzerinlösung oder mit 0,9%iger NaCl-Lösung geblockt und 14 Tage bei verschiedenen pH-Werten in künstlichem Urin gelagert. Nach diesem Zeitraum wurde die rückgewonnene Flüssigkeit aus dem Katheterballon gemessen. Ergebnisse: Bei allen Katheterballons wurde eine Reduktion des Ballonvolumens von maximal 20 % festgestellt. Weder das verwendete Füllmedium noch das Kathetermaterial hatte signifikante Auswirkungen auf das Ausmaß der Volumenänderung. Schlußfolgerung: Die Änderung des Urin-pH führt nicht zu Volumenverschiebungen im Katheterballon.

    Full Text Available A hymn must be sung to be heard ... : Aspects that could influence the reception of hymns and psalms. The most recent official hymnal in Afrikaans, Liedboek van die Kerk, was taken into use in 2001. Some hymns and psalms were immediately sung with enthusiasm whereas others remained unused, which is true especially for many of the metrical psalms. The most prominent reason for not singing some hymns or psalms is that they are unknown – text as well as tune. It is, however, often assumed that the reason why hymns and psalms are unknown is primarily because their tunes would be too difficult to sing. The role of the text and other aspects are not taken into account sufficiently. In this article, these one-sided views regarding the tunes are challenged, and it is argued that there could be many other reasons why hymns and psalms are not used.

    Für das COMPASS-Experiment am CERN wurden Hodoskope aus szintillierenden Fasern entwickelt, getestet und in das Experiment integriert. Die Spurrekonstruktion im oder in unmittelbarer Nähe des Primärstrahls stellt hohe Anforderungen in Bezug auf Ratenfestigkeit, Zeitauflösung, Nachweiseffizienz und Strahlenhärte aller Detektorkomponenten. Vorstudien zur Eignung von szintillierenden Fasern und Lichtleitern in Verbindung mit Vielkanal-Photomultipliern führten zur Fertigung eines Prototyps, der bei nominalen Bedingungen intensiv getestet wurde. Mit den hieraus gewonnen Erfahrungen wurden insgesamt vier Faserhodoskope realisiert und im Rahmen des COMPASS-Experiments betrieben. Hierbei wurde eine intrinsische Detektoreffizienz von nahezu 100% erreicht. Mit einer Zeitauflösung von etwa 450 ps bei gleichzeitig geringen Treffermultiplizitäten ist eine eindeutige Rekonstruktion von Teilchenspuren auch bei Strahlraten von bis zu 100 MHz möglich. Im Dauerbetrieb über 250 Tage während zweier Strahlzeiten zeigte...

    This work aimed to investigate glottal adduction in the case of the singing of diatonic D major ascending scales with different dynamic shapings on vowel [a:] by 10 classically trained male singers. The parameters obtained by inverse filtering-closed quotient (CQ), normalized amplitude quotient (NAQ), and the level difference between the first two partials of the glottal flow waveform spectrum (H1-H2)-all indicated statistically significant systematic changes when singers sang (1) with habitual dynamics without intentional dynamic changes; (2) with sempre crescendo from piano to forte; and (3) with sempre diminuendo from forte to piano. Adduction on average was lower if the tone with the same pitch was sung piano compared with when it was sung forte. The piano tones with the limit of one and the same dynamic task were sung with lower adduction on average compared with one octave higher or lower tones sung forte, although here the agreement between different parameters was poorer and the individual variability was greater. There was only a moderate negative correlation between CQ and NAQ (r = -0.41) but a strong negative correlation between CQ and H1-H2 (r = -0.8). CQ showed a moderate positive correlation with sound level but no significant correlation with pitch. NAQ showed a strong and significant positive correlation with pitch but not with sound level (except when it was calculated only at constant pitch). Some of the most experienced singers used quite high glottal adduction levels, questioning the concept of whether flow phonation is always the favorite classical style.

    A spectrogram of a singer’s vibrato presents a striking way to introduce students to frequency, Fourier spectra, and modulation. Vibrato is discussed from the perspectives of the physicist and the musician. A dramatic spectrogram is included where coauthor soprano Michel suppresses her vibrato so that acoustical characteristics can be compared to the same note sung with vibrato. A video (Ruiz 2017 Video: vibrato http://mjtruiz.com/ped/vibrato/) is provided of this demonstration.

  2. Speech versus singing: Infants choose happier sounds

    Full Text Available Infants prefer speech to non-vocal sounds and to non-human vocalizations, and they prefer happy-sounding speech to neutral speech. They also exhibit an interest in singing, but there is little knowledge of their relative interest in speech and singing. The present study explored infants’ attention to unfamiliar audio samples of speech and singing. In Experiment 1, infants 4-13 months of age were exposed to happy-sounding infant-directed speech versus hummed lullabies by the same woman. They listened significantly longer to the speech, which had considerably greater acoustic variability and expressiveness, than to the lullabies. In Experiment 2, infants of comparable age who heard the lyrics of a Turkish children’s song spoken versus sung in a joyful/happy manner did not exhibit differential listening. Infants in Experiment 3 heard the happily sung lyrics of the Turkish children’s song versus a version that was spoken in an adult-directed or affectively neutral manner. They listened significantly longer to the sung version. Overall, happy voice quality rather than vocal mode (speech or singing was the principal contributor to infant attention, regardless of age.

    Although previous studies suggest that music may facilitate verbal learning in a healthy population, such a mnemonic effect has seldom been investigated in Alzheimer's disease (AD). Moreover, memorization of texts was generally compared when either sung or spoken. In the present study, it was examined whether the benefit observed on verbal learning was specific to music or whether an associative context binding items together led to similar benefits, regardless of the nature of the association. Twelve patients with mild AD and 15 healthy controls learned texts presented with either a musical (sung) or a nonmusical association (spoken associated to a silent movie sequence) or without association (spoken alone). Immediate and delayed (after a 5-min delay) recall was measured. Main results showed that (a) sung texts were better remembered than spoken texts, both immediately and after a retention delay, for both groups; (b) the musical benefit was robust, being observed in most AD patients; (c) the nonmusical association may also facilitate verbal learning but to a lesser extent. A musical association during the encoding stage facilitates learning and retention in AD. Furthermore, this advantage seemed quite specific to music. The results are discussed with respect to the clinical applications in AD; theoretical implications are highlighted to explain the power of music as a mnemonic technique.

    2015-02-15

    Two important applications of electron vortex beams are in electron magnetic chiral dichroism (EMCD) measurements and nanoparticle manipulation. In both cases orbital angular momentum () transfer between the vortex beam and the specimen due to dynamic scattering is critical. In general the pendellösung consists of short and long wavelength oscillations. The former is due to interference between the tightly bound 1s and more dispersive non-1s Bloch states, while the latter is due to interference between the non-1s states. For EMCD experiments with ±ħ angular momentum beams, momentum transfer can be minimised by selecting the appropriate aperture size, so that the probe wavefunction approximately matches that of the 2p-type Bloch states. For manipulating nanoparticles with large angular momentum beams small apertures are required to excite the 1s state and thereby enhance the short wavelength oscillations in . This enables efficient momentum transfer to the specimen, provided the nanoparticle dimension corresponds to a minimum in the pendellösung. - Highlights: • Dynamic scattering of vortex beams is analysed using Bloch waves. • Fundamental origins of pendellösung oscillations are identified. • Effect on magnetic dichroism measurements and nanoparticle manipulation is discussed.

  6. On the electron vortex beam wavefunction within a crystal

    2015-10-15

    Electron vortex beams are distorted by scattering within a crystal, so that the wavefunction can effectively be decomposed into many vortex components. Using a Bloch wave approach equations are derived for vortex beam decomposition at any given depth and with respect to any frame of reference. In the kinematic limit (small specimen thickness) scattering largely takes place at the neighbouring atom columns with a local phase change of π/2 rad. When viewed along the beam propagation direction only one vortex component is present at the specimen entrance surface (i.e. the ‘free space’ vortex in vacuum), but at larger depths the probe is in a mixed state due to Bragg scattering. Simulations show that there is no direct correlation between vortex components and the pendellösung, i.e. at a given depth probes with relatively constant can be in a more mixed state compared to those with more rapidly varying . This suggests that minimising oscillations in the pendellösung by probe channelling is not the only criterion for generating a strong electron energy loss magnetic circular dichroism (EMCD) signal. - Highlights: • Equations are derived for vortex decomposition due to scattering within a crystal. • There is no direct correlation between vortex decomposition and pendellösung. • Results are also discussed in the context of EMCD measurements.

  7. Effect of musical experience on verbal memory in Williams syndrome: evidence from a novel word learning task.

    Science.gov (United States)

    Martens, Marilee A; Jungers, Melissa K; Steele, Anita L

    2011-09-01

    Williams syndrome (WS) is a neurogenetic developmental disorder characterized by an increased affinity for music, deficits in verbal memory, and atypical brain development. Music has been shown to improve verbal memory in typical individuals as well as those with learning difficulties, but no studies have examined this relationship in WS. The aim of our two studies was to examine whether music can enhance verbal memory in individuals with WS. In Study 1, we presented a memory task of eight spoken or sung sentences that described an animal and identified its group name to 38 individuals with WS. Study 2, involving another group of individuals with WS (n=38), included six spoken or sung sentences that identified an animal group name. In both studies, those who had participated in formal music lessons scored significantly better on the verbal memory task when the sentences were sung than when they were spoken. Those who had not taken formal lessons showed no such benefit. We also found that increased enjoyment of music and heightened emotional reactions to music did not impact performance on the memory task. These compelling findings provide the first evidence that musical experience may enhance verbal memory in individuals with WS and shed more light on the complex relationship between aspects of cognition and altered neurodevelopment in this unique disorder.

    The eight-node and forty-DOF piezoelectric shell element were applied to shape control of a flat shell structure. By the direct and converse effects, a distributed piezoelectric sensor layer was used to monitor the shape deformation and a distributed actuator layer was used to suppresse the deflection. A finite element model was for static response of laminated shell with piezoelectric sensors/actuators was derived. The model was verified by calculating piezoelectric polymeric PVDF bimorph beam. The results are in good agreement with those obtained by theoretical analysis of Tzou[1] and Hwang[2]. A case study of the static shape control of a flat shell structure is presented.

    Full Text Available We demonstrate fluorescence imaging by two-photon excitation without scanning in biological specimens as previously described by Hwang and co-workers, but with an increased field size and with framing rates of up to 100 Hz. During recordings of synaptically-driven Ca(2+ events in primary rat hippocampal neurone cultures loaded with the fluorescent Ca(2+ indicator Fluo-4 AM, we have observed greatly reduced photo-bleaching in comparison with single-photon excitation. This method, which requires no costly additions to the microscope, promises to be useful for work where high time-resolution is required.

    Four principal mango cultivars (Tainong No.1, Irwin, JinHwang and Keitt) grown in southern China were selected, and their physico-chemical and antioxidant properties were characterized and compared. Of all the four cultivars, Tainong No.1 had highest content of total phenols, ρ-coumaric acid, sinapic acid, quercetin, titratable acidity, citric acid, malic acid, fructose, higher antioxidant activities (DPPH, FRAP) and L(*), lower pH, PPO activity and individual weight. Keitt mangoes showed significantly (pmangoes exhibited significantly (pmango cultivars to be differentiated clearly based on all these physico-chemical and antioxidant properties determined in the study.

    Antimicrobial peptides (AMPs) are important components of the host innate defense mechanism against invading pathogens. Our previous studies have shown that the outer membrane protein, OprI from Pseudomonas aeruginosa or its homologue, plays a vital role in the susceptibility of Gram-negative bacteria to cationic α-helical AMPs (Y.

    It is well known that Taiwan's IC industry is in the very leading front of the world, and production of 65 nm devices was launched in 2006. Within a few years, the need of high-k dielectrics and metal gates is eminent and truly indispensable. Professor H.L. Hwang (the author) organized 12 professors and 50 graduate students of National Tsing Hua University and Chiao Tung University, and executed this particular project, which is sponsored by the Ministry of Economic Affairs of Republic of China, and is aimed at treating efficiently this problem and transferred the critical technologies to industry in a time frame of 3 years.

  1. Origin of Charge Density at LaAlO3 on SrTiO3 Heterointerfaces: Possibility of Intrinsic Doping

    As discovered by Ohtomo and Hwang, a large sheet charge density with high mobility exists at the interface between SrTiO3 and LaAlO3. Based on transport, spectroscopic, and oxygen-annealing experiments, we conclude that extrinsic defects in the form of oxygen vacancies introduced by the pulsed laser deposition process used by all researchers to date to make these samples is the source of the large carrier densities. Annealing experiments show a limiting carrier density. We also present a model that explains the high mobility based on carrier redistribution due to an increased dielectric constant.

  2. 'We aren't quite as good, but we sure are cheap': prospects for disruptive innovation in medical care and insurance markets.

    2008-01-01

    The concept of "disruptive innovation" by new products of moderately lower quality and much lower cost is useful for the medical care sector. Such products are rarely offered, and when they are (as in the case of health maintenance organizations), they are subject to intense criticism. This Perspective argues that both the legal system and accepted discourse in public policy have inhibited discussion of such alternatives; indeed, the paper by Jason Hwang and Clay Christensen loses its focus on them at the end. The applicability of this concept is quite limited but, given sufficient changes in framing and regulating, might be helpful in the future.

    The signcryption is a relatively new cryptographic technique that is supposed to fulfill the functionalities of encryption and digital signature in a single logical step. Several signcryption schemes are proposed throughout the years, each of them having its own problems and limitations. In this paper, the security of a recent signcryption scheme, i.e. Hwang et al.'s scheme is analyzed, and it is proved that it involves several security flaws and shortcomings. Several devastating attacks are also introduced to the mentioned scheme whereby it fails all the desired and essential security attributes of a signcryption scheme.

Recently, it has become evident that some TiO2 particles have a considerable cytotoxic effect in normal human cells. However, the molecular basis for the cytotoxicity of TiO2 has yet to be defined.Methods and results: In this study, we demonstrated that combined treatment with TiO2 nanoparticles sized less than 100 nm and ultraviolet A irradiation induces apoptotic cell death through reactive oxygen species-dependent upregulation of Fas and conformational activation of Bax in normal human cells. Treatment with P25 TiO2 nanoparticles with a hydrodynamic size distribution centered around 70 nm (TiO2P25–70 together with ultraviolet A irradiation-induced caspase-dependent apoptotic cell death, accompanied by transcriptional upregulation of the death receptor, Fas, and conformational activation of Bax. In line with these results, knockdown of either Fas or Bax with specific siRNA significantly inhibited TiO2-induced apoptotic cell death. Moreover, inhibition of reactive oxygen species with an antioxidant, N-acetyl-L-cysteine, clearly suppressed upregulation of Fas, conformational activation of Bax, and subsequent apoptotic cell death in response to combination treatment using TiO2P25–70 and ultraviolet A irradiation.Conclusion: These results indicate that sub-100 nm sized TiO2 treatment under ultraviolet A irradiation induces apoptotic cell death through reactive oxygen species-mediated upregulation of the death receptor, Fas, and activation of the preapoptotic protein

    In his Mandala model of the self, Taiwanese scholar Kwang-Kuo Hwang sees each human being as a combination or intersection of private individual and social person, and also of knowledge and action. To further elaborate the model-with a particular emphasis on teaching/learning, the development of the ideal self and spiritual transcendence-this article will explore the psychological process of self-cultivation in the light of traditional Confucian thinking, which means keeping a balance between inner/outer and self/other. The Neo-Confucian thinker Zhongsha Mou's theories of "the awareness of unexpected developments" and his meditation/cognitive thinking opposition will also be discussed. The analyzed sources will include the traditional Confucian classics (the Four Books and Liji, or Classic of Rites) and especially the "Lessons for Learning (Xue-Ji)" in the Classic of Rites (Liji), along with the relevant textual research. Based upon a cultural-semantic analysis of these classics as well as of Hwang's central ideas, the author attempts to further conceptualize the process of cultivating the ideal self in Confucian education.

    Full Text Available This research aims to apply the Fama-French models and test the effect of alternative variable of bond yield spread, default spread (RBBB – RAAA and RAAA – RF, and the term spread (RSUN10-RSUN1, as proxy variables of the business cycle, in IDX stock data during 2005-2010. Four types of asset pricing models tested are Sharpe-Lintner CAPM, Fama-French models, Hwang et al.model, and hybrid model. The results showed that the size effect and value effect has an impact on excess stock returns. Slopes of market beta, SMB, and HML are more sensitive to stock big size and high B / M. Default spreads and term spreads in Hwang et al. model can explain the value effect, and weakly explain the size effect, meanwhile the power of explanation disappeared on Hybrid models. Based on the assessment adjusted R2 and the frequency of rejection of non-zero alpha, is found that the hybrid model is the most suitable model.

    New level structures for ^121,123Cd will be presented that were determined in the study of the ^64Ni- and ^76Ge-induced fission of ^238U at Gammasphere [1]. A number of transitions were previously observed by Hwang et al. from which yrast levels were identified with maximum proposed spins of 27/2- and 23/2- in ^121,123Cd, respectively [2]. If the additional transitions have stretched E2 multipolarity, these level structures would be extended to 31/2- at 4083 keV, and 35/2- at 5365 keV in ^121,123Cd, respectively. These level sequences will be compared to existing levels in the lighter odd-mass Cd nuclei and the isomeric structures and calculations in the heavier odd-mass Cd nuclei.[4pt] [1] C. J. Chiara, I.

Of the cognitive deficits revealed in schizophrenia or posttraumatic stress disorder (PTSD patients, the current article provides a brief review of deficit in episodic memory, which is highly predictive of patients’ quality of life and global functioning. In particular, we have focused on studies that compared relational and item-specific memory performance in schizophrenia and PTSD, because measures of relational and item-specific memory are considered the most promising constructs for immediate tangible development of clinical trial paradigm. The behavioral findings of schizophrenia are based on the tasks developed by the Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia (CNTRICS initiative and the Cognitive Neuroscience Test Reliability and Clinical Applications for Schizophrenia (CNTRACS Consortium. The findings we reviewed consistently showed that schizophrenia and PTSD are closely associated with more severe impairments in relational memory compared to item-specific memory. Candidate brain regions involved in relational memory impairment in schizophrenia and PTSD are also discussed.

    We analyze the design and specifications of the Sun-and-Stars Time-Determining group of instruments (Ilseong-jeongsi-ui, 日星定時儀) made during the Joseon dynasty. According to the records of the Sejong Sillok (Veritable Records of King Sejong), Sun-and-Stars Time-Determining Instruments measure the solar time of day and the sidereal time of night through three rings and an alidade. One such instrument, the Simplified Time-Determining Instrument (So-jeongsi-ui, 小定時儀), is made without the essential component for alignment with the celestial north pole. Among this group of instruments, only two bronze Hundred-Interval-Ring Sundials (Baekgak-hwan-Ilgu, 百刻環日晷) currently exist. A comparison of the functions of these two relics with two Time-Determining Instruments suggests that the Hundred-Interval-Ring Sundial is a Simplified Sundial (So-ilyeong, 小日影), as recorded in the Sejong Sillok and the Seongjong Sillok (Veritable Records of King Seongjong). Furthermore, the Simplified Sundial is a model derived from the Simplified Time-Determining Instrument. During the King Sejong reign, the Sun-and-Stars Time-Determining Instruments were used in military camps of the kingdom’s frontiers, in royal ancestral rituals, and in royal astronomical observatories.

Based on solubility measurements, surface-modified pranlukast hemihydrate microparticles were manufactured using the spray-drying method with hydroxypropylmethyl cellulose, sucrose laurate, and water and without the use of an organic solvent. The hydrophilicity of the surface-modified pranlukast hemihydrate microparticle increased, leading to enhanced dissolution and oral bioavailability of pranlukast hemihydrate without a change in crystallinity. The surface-modified microparticles with an hydroxypropylmethyl cellulose/sucrose laurate ratio of 1:2 showed rapid dissolution of up to 85% within 30 minutes in dissolution medium (pH 6.8 and oral bioavailability higher than that of the commercial product, with approximately 2.5-fold and 3.9-fold increases in area under the curve (AUC0→12 h and peak plasma concentration, respectively. Therefore, the surface-modified microparticle is an effective oral drug delivery system for the poorly water-soluble therapeutic pranlukast hemihydrate.

    Full Text Available Introduction: Many patients with aphasia, particularly those with nonfluent aphasia, have been observed to be able to sing the lyrics of songs more easily than they can speak the same words (Wan et al., 2010. The observation that not only singing, but even intoning words, can facilitate speech output in nonfluent aphasia patients provided the foundation for Melodic Intonation Therapy (MIT; Sparks, 1974, an intensive therapy lasting ten or more weeks (Schlaug et al., 2008. The current study aims to look at patients with aphasia in their ability to complete song lyrics by either singing, speaking, or humming them. Methods: Thus far, 11 patients with aphasia and 6 age- matched healthy controls have participated in an experimental stem-completion task examining singing abilities. The task consists of three conditions each consisting of 20 well-known songs and all participants completed all three conditions. Participants heard the first half of a phrase that was either sung in its original format (e.g., “Mary had a Little Lamb”, spoken, or intoned on the syllable “bum”, and were asked to complete the phrase according to the format in which the stimulus was presented, (i.e., either by singing, speaking the words, or humming/singing the melody correspondingly. The task was untimed, though most finished the task within an hour. Each participant completed a survey about their musical experience. Results: Patients were scored on their ability to complete the melody and words together in the sung condition, only the words in the spoken condition, and only the tune of the song in the melody condition. A parametric t-test indicated no significant difference between groups in the sung condition (mean patients=45.3%, mean controls=68.2%, t-value= -1.96, p=0.0684, though this test almost reached significance. There was also no significant difference between groups in the melody condition (mean patients= 18.2%, mean controls=20.0%, t-value= -0.335, p=0

The purpose of this study was to examine the neural substrates involved in the accessing "song lexicon" as corresponding to a representational system that might provide links between the musical and phonological lexicons using positron emission tomography (PET. We exposed participants to auditory stimuli consisting of familiar and unfamiliar songs presented in three ways: sung lyrics (song, sung lyrics on a single pitch (lyrics, and the sung syllable 'la' on original pitches (melody. The auditory stimuli were designed to have equivalent familiarity to participants, and they were recorded at exactly the same tempo. Eleven right-handed nonmusicians participated in four conditions: three familiarity decision tasks using song, lyrics, and melody and a sound type decision task (control that was designed to engage perceptual and prelexical processing but not lexical processing. The contrasts (familiarity decision tasks versus control showed no common areas of activation between lyrics and melody. This result indicates that essentially separate neural networks exist in semantic memory for the verbal and melodic processing of familiar songs. Verbal lexical processing recruited the left fusiform gyrus and the left inferior occipital gyrus, whereas melodic lexical processing engaged the right middle temporal sulcus and the bilateral temporo-occipital cortices. Moreover, we found that song specifically activated the left posterior inferior temporal cortex, which may serve as an interface between verbal and musical representations in order to facilitate song recognition.

    Full Text Available The DPRK's (Democratic People's Republic of Korea or North Korea support for terrorism began as an ideologically-based policy financed by the Soviet Union that eventually led to a policy designed to put money into the coffers of the elite in Pyongyang—in short, a "proliferation for hire" policy. This article articulates a brief history of the North Korean regime, the rise to power of Kim Il-sung and his son, Kim Jong-il, and North Korea's persistent support to terrorist groups around the globe.

  8. Pronunciation and Articulation for Singing Chinese Works

    For singing Chinese works, pronunciation and articulation are the most essential and the most crucial factors. Their beginning should be brief, middle should be melodious and long-lasting, and end should be as clear and crisp as crystal. Considering from pronunciations, Chinese works can be divided into two categories:one is comprehensive style emphasizing clear enunciation; the other is local folk song that should be sung based on corresponding local accent of the works. Besides, based on correct pronunciation and articulation, balance between pro-nunciation and articulation should be achieved, both the essence of western traditional mode of singing and Chinese traditional music should be followed and inherited.

    The first experimental study of the Schwinger interaction of polarized neutrons with an electric field of a noncentrosymmetric perfect crystal (α-quartz) was made for two wave dynamical diffraction. Phase shifts of Pendellösung fringes for two different spin to crystal field orientations were measured. The theory of the effect is given. The calculated value of SiO2 (11 overline20) interplanar electr field, seen by the diffracted neutron, is 2.1 × 10 8 V/cm. This is in good agreement with the experimental result: (1.8 ± 0.3) × 10 8 V/cm.

    We discuss the BCI based on inner tones and inner music. We had some success in the detection of inner tones, the imagined tones which are not sung aloud. Rather easily imagined and controlled, they offer a set of states usable for BCI, with high information capacity and high transfer rates. Imagination of sounds or musical tunes could provide a multicommand language for BCI, as if using the natural language. Moreover, this approach could be used to test musical abilities. Such BCI interface could be superior when there is a need for a broader command language. Some computational estimates and unresolved difficulties are presented. PMID:19503802

    Full Text Available ABSTRACT Musical hallucination is a type of complex auditory hallucination. Possible etiologies are deafness, psychiatric disorders such as schizophrenia, major depression, use of medication and stress, besides neurologic diseases including epilepsy, stroke and cancer. Uncommon etiologies encompass infectious diseases, metabolic disorders, and sensory deprivation. Although musical hallucinations have a major impact on patients' lives, they have been undervalued and understudied in the literature. We report a case of a 79-year-old woman with musical hallucination (hearing a sung National anthem without cognitive impairment or hearing loss. The patient had preserved insight of her complaint and responded well to neuroleptics.

    11 infants with Down's syndrome (MA 9.2 months, CA 12.7 months) and 10 of 11 nonhandicapped infants (MA 9.6 months, CA 9.3 months) demonstrated that they could operate an automated device which enabled them to choose to listen to 1 of a pair of auditory signals. All subjects showed preferential responding. Both groups of infants showed a significant preference for nursery rhymes sung by a female voice rather than played on musical instruments. The infants with Down's syndrome had much longer response durations for the more complex auditory stimuli. The apparatus provides a useful technique for studying language development in both normal and abnormal populations.

    Full Text Available This article reconstructs the social uses of the décimas (ten-line stanzas sung in the insurgent camps during the war for independence that began in Cuba in 1895. Through a review of personal diaries, newspapers, and photos of the conflict, the article attempts to answer various questions: What emotions did this poetic musical genre produce in the everyday life of the combatants? How did the war affect such cultural practices? Is it possible to find black and mulatto decimistas among the Cuban troops? What role did officers play in these everyday forms of expression about the political life of the country?

    2014-01-01

    The quality of a music performance can be lessened or enhanced if the performer experiences stressful conditions. In addition, the quality of a sung performance requires control of the fundamental frequency of the voice, which is particularly sensitive to stress. The present study aimed to clarify the effects of stress on singing voice accuracy. Thirty-one music students were recorded in a stressful condition (ie, a music examination) and a nonstressful condition. Two groups were defined according to the challenge level of the music examination (first and second music levels). Measurements were made by self-reported state anxiety (CSAI-2R questionnaire) and by observing heart rate activity (electrocardiogram) during each performance. In addition, the vocal accuracy of the sung performances was objectively analyzed. As expected, state anxiety and heart rate were significantly higher on the day of the music examination than in the nonstressful condition for all the music students. However, the effect of stress was positive for the first-year students but negative for the second-year students, for whom the music examination was particularly challenging. In addition, highly significant correlations were found between the intensity of cognitive symptoms and the vocal accuracy criteria. This study highlights the contrasting effects of stress on singing voice accuracy but also the need to consider the challenge level and perception of the symptoms in experimental and pedagogical settings.

    Full Text Available This fMRI study examines shared and distinct cortical areas involved in the auditory perception of song and speech at the level of their underlying constituents: words, pitch and rhythm. Univariate and multivariate analyses were performed on the brain activity patterns of six conditions, arranged in a subtractive hierarchy: sung sentences including words, pitch and rhythm; hummed speech prosody and song melody containing only pitch patterns and rhythm; as well as the pure musical or speech rhythm.Systematic contrasts between these balanced conditions following their hierarchical organization showed a great overlap between song and speech at all levels in the bilateral temporal lobe, but suggested a differential role of the inferior frontal gyrus (IFG and intraparietal sulcus (IPS in processing song and speech. The left IFG was involved in word- and pitch-related processing in speech, the right IFG in processing pitch in song.Furthermore, the IPS showed sensitivity to discrete pitch relations in song as opposed to the gliding pitch in speech. Finally, the superior temporal gyrus and premotor cortex coded for general differences between words and pitch patterns, irrespective of whether they were sung or spoken. Thus, song and speech share many features which are reflected in a fundamental similarity of brain areas involved in their perception. However, fine-grained acoustic differences on word and pitch level are reflected in the activity of IFG and IPS.

Currently, no effective strategies are known to prevent facial wrinkles. We assessed the beneficial effects of bee-venom serum on the clinical signs of aging skin. Our results show that bee-venom serum treatment clinically improved facial wrinkles by decreasing total wrinkle area, total wrinkle count, and average wrinkle depth. Therefore, bee-venom serum may be effective for the improvement of skin wrinkles. Keywords: bee venom, wrinkle, area, count, depth

    2014-11-16

    Williams syndrome (WS) is a genetic disorder characterized by intellectual delay and an affinity for music. It has been previously shown that familiar music can enhance verbal memory in individuals with WS who have had music training. There is also evidence that unfamiliar, or novel, music may also improve cognitive recall. This study was designed to examine if a novel melody could also enhance verbal memory in individuals with WS, and to more fully characterize music training in this population. We presented spoken or sung sentences that described an animal and its group name to 44 individuals with WS, and then tested their immediate and delayed memory using both recall and multiple choice formats. Those with formal music training (average duration of training 4½ years) scored significantly higher on both the spoken and sung recall items, as well as on the spoken multiple choice items, than those with no music training. Music therapy, music enjoyment, age, and Verbal IQ did not impact performance on the memory tasks. These findings provide further evidence that formal music lessons may impact the neurological pathways associated with verbal memory in individuals with WS, consistent with findings in typically developing individuals.

    2010-08-01

    Musical mnemonics have a long and diverse history of popular use. In addition, music processing in general is often considered spared by the neurodegenerative effects of Alzheimer's disease (AD). Research examining these two phenomena is limited, and no work to our knowledge has explored the effectiveness of musical mnemonics in AD. The present study sought to investigate the effect of music at encoding on the subsequent recognition of associated verbal information. Lyrics of unfamiliar children's songs were presented bimodally at encoding, and visual stimuli were accompanied by either a sung or a spoken recording. Patients with AD demonstrated better recognition accuracy for the sung lyrics than the spoken lyrics, while healthy older adults showed no significant difference between the two conditions. We propose two possible explanations for these findings: first, that the brain areas subserving music processing may be preferentially spared by AD, allowing a more holistic encoding that facilitates recognition, and second, that music heightens arousal in patients with AD, allowing better attention and improved memory.

    Full Text Available One of the oral literature products of Turkish culture which is shared from centuries before is called lullaby (Baby songs. Lullabies contain Turkish Nation’s common cultural items that gather us together. Recent researches show that the lullabies which are sung for babies has an educational dimension. With their rich themes lullabies tells about the main problems that the babies and children may confront in their school life and further years. The relation between lullabies and mathematics has been searched at this research. For this purpose the concepts of pre-school education for 3-6 year-old children has been dealt with and a categorising has been made. Then the product called “Turkish Lullabies 1” has been analysed by utilising context analysing of these categorising. According to the findings of the research, the lullabies that have been sung for centuries contain more educational concept than the concepts that are planned to be applied at the pre-school educational programme.

    The earliest pre-Linnaean fungal genera are briefly discussed here with special emphasis on the nomenclatural connection with the genus Cordyceps Fr. Since its valid publication under the basidiomycetous genus Clavaria Vaill. ex L. (Clavaria militaris L. Sp. Pl. 2:1182, 1753), the genus Cordyceps has undergone nomenclatural changes in the post-Linnaean era, but has stood firmly for approximately 200 years. Synonyms of Cordyceps were collected from different literature sources and analyzed based on the species they represent. True synonyms of Cordyceps Fr. were defined as genera that represented species of Cordyceps Fr. emend. G. H. Sung, J. M. Sung, Hywel-Jones & Spatafora. The most common synonyms of Cordyceps observed were Clavaria and Sphaeria Hall, reported in the 18th and in the first half of the 19th century, respectively. Cordyceps, the oldest genus in the Cordyceps s. s. clade of Cordycipitaceae, is the most preferred name under the "One Fungus = One Name" principle on priority bases. PMID:25071376

  18. Singing with yourself: evidence for an inverse modeling account of poor-pitch singing.

    2014-05-01

    Singing is a ubiquitous and culturally significant activity that humans engage in from an early age. Nevertheless, some individuals - termed poor-pitch singers - are unable to match target pitches within a musical semitone while singing. In the experiments reported here, we tested whether poor-pitch singing deficits would be reduced when individuals imitate recordings of themselves as opposed to recordings of other individuals. This prediction was based on the hypothesis that poor-pitch singers have not developed an abstract "inverse model" of the auditory-vocal system and instead must rely on sensorimotor associations that they have experienced directly, which is true for sequences an individual has already produced. In three experiments, participants, both accurate and poor-pitch singers, were better able to imitate sung recordings of themselves than sung recordings of other singers. However, this self-advantage was enhanced for poor-pitch singers. These effects were not a byproduct of self-recognition (Experiment 1), vocal timbre (Experiment 2), or the absolute pitch of target recordings (i.e., the advantage remains when recordings are transposed, Experiment 3). Results support the conceptualization of poor-pitch singing as an imitative deficit resulting from a deficient inverse model of the auditory-vocal system with respect to pitch.

    electron temperature, Te, fluctuations through standard cross-correlation analysis methods. In Alcator C-Mod, a new CECE diagnostic has been installed[Sung RSI 2012], and interesting phenomena have been observed in various plasma conditions. We find that local Te fluctuations near the edge (ρ ~ 0:8 decrease across the linearto- saturated ohmic confinement transition, with fluctuations decreasing with increasing plasma density[Sung NF 2013], which occurs simultaneously with rotation reversals[Rice NF 2011]. Te fluctuations are also reduced across core rotation reversals with an increase of plasma density in RF heated L-mode plasmas, which implies that the same physics related to the reduction of Te fluctuations may be applied to both ohmic and RF heated L-mode plasmas. In I-mode plasmas, we observe the reduction of core Te fluctuations, which indicates changes of turbulence occur not only in the pedestal region but also in the core across the L/I transition[White NF 2014]. The present CECE diagnostic system in C-Mod and these experimental results are described in this paper.

La gzhas, or Amdo Tibetan love songs, are sung between young men and women to express their love to each other. Several terms are available for this type of love song in Amdo Tibetan. La gzhas is the most common term for such songs in written Tibetan, la meaning 'mountain pass' and gzhas 'song'. In oral Amdo Tibetan, it is la-ye, a homophone of the literary term. Ri glu literally means mountain song, and this term matches the Chinese term for love songs, shan'ge. These two terms indicate where this song is often sung, in the mountains, far away from houses, villages and tents, in places where there are few people around. Rogs 'then has a more romantic connotation, rogs meaning friend or lover, and 'then meaning to pull, or hookup. The lyrics of la gzhas express feelings between men and women.

    Full Text Available An overview of all the 1,973 songs that have appeared in seventy Estonian, Latvian, and Lithuanian national song celebration programmes from 1869 to the present day reveals a richly innovative, creative tradition: in each of the three festival repertoires, 74–84 percent of the songs were performed only once over the entire history of the national celebrations. When concert participants choose to repeat songs sung in previous years, they identify these songs as heritage. Sometimes, most notably in the retrospective Estonian programmes of 1969 and 2014, a large portion of the concert repertoire was repeated from the past. The tradition as a whole, however, is not necessarily past-oriented. Some celebrations have turned away from heritage. In the 1928 Estonian celebration, for example, only 2 percent of the programme (only one song had ever been sung in an earlier celebration. This, too, is a heritage of song celebrations: future organisers are free to decide how many, if any, songs they wish to repeat from earlier festivals. The song festival tradition allows both innovative and conservative choice of repertoire at any given festival.

  3. Dynamic scattering of electron vortex beams--a Bloch wave analysis.

    Mendis, B G

    2015-02-01

    Two important applications of electron vortex beams are in electron magnetic chiral dichroism (EMCD) measurements and nanoparticle manipulation. In both cases orbital angular momentum (〈Lz〉) transfer between the vortex beam and the specimen due to dynamic scattering is critical. In general the 〈Lz〉 pendellösung consists of short and long wavelength oscillations. The former is due to interference between the tightly bound 1s and more dispersive non-1s Bloch states, while the latter is due to interference between the non-1s states. For EMCD experiments with ±ħ angular momentum beams, momentum transfer can be minimised by selecting the appropriate aperture size, so that the probe wavefunction approximately matches that of the 2p-type Bloch states. For manipulating nanoparticles with large angular momentum beams small apertures are required to excite the 1s state and thereby enhance the short wavelength oscillations in 〈Lz〉. This enables efficient momentum transfer to the specimen, provided the nanoparticle dimension corresponds to a minimum in the 〈Lz〉 pendellösung.

    This study is on fluoride uptake into enamel following fluoride precipitation with calcium hydroxide. Five specimens each from 12 bovine incisors were polished, covered with a salivary pellicle, and distributed into five groups (n=12). A fluoride solution (43,500 ppm F from magnesiumfluorosilicate, copper-(II)-fluorosilicate and sodium-fluoride, pH 2; Tiefenfluorid Touchierlösung, Humanchemie) and Ca(OH)2-solution (Tiefenfluorid Nachtouchierlösung) were applied subsequently in group TN. "Touchierlosung" only was used in group T, sodium-fluoride (43,500 ppm F, pH 2) in group NaF, and aminefluoride (Elmex fluid, 10,000 ppm F, pH 4) in group EF. No fluoride was used in group NK (negative control). Following rinsing and 24 h storage in artificial saliva surface KOH-soluble fluoride content (KOHF), and structurally bound fluoride content (SBF) from three layers (0-33, 33-66 and 66-99 pm) was determined by fluoride electrode procedures. KOHF (median in microg/cm2) of NK was below the lower limit of quantification of the fluoride electrode. The other group values were significantly higher (Mann-Whitney test, p precipitation reaction with Ca(OH)2 following fluoridation did not increase enamel fluoride uptake.

Using a first derivative Gaussian function as prototype wavelet, we apply the pointwise product of the wavelet coefficients (PWCs over some successive scales, in order to enhance the peak amplitude of the modulus maxima line and to reduce noise. The R wave corresponds to two modulus maximum lines with opposite signs (min-max of multi-scale product. The proposed algorithm does not include regularity analysis but only amplitude-based criteria.

    2016-08-01

    The Rabi model, a two-level atom coupled to a harmonic oscillator, can undergo a second-order quantum phase transition (QPT) [M.-J. Hwang et al., Phys. Rev. Lett. 115, 180404 (2015), 10.1103/PhysRevLett.115.180404]. Here we show that the Rabi QPT accompanies critical behavior in the higher-energy excited states, i.e., the excited-state QPT (ESQPT). We derive analytic expressions for the semiclassical density of states, which show a logarithmic divergence at a critical energy eigenvalue in the broken symmetry (superradiant) phase. Moreover, we find that the logarithmic singularities in the density of states lead to singularities in the relevant observables in the system such as photon number and atomic polarization. We corroborate our analytical semiclassical prediction of the ESQPT in the Rabi model with its numerically exact quantum mechanical solution.

    2008-07-01

    This paper provides a critical commentary on a suite of eight papers, which focus on conceptual change research in science education. Responses by Mercer, Smardon and Wells to a paper by Treagust and Duit are observed to reflect the backgrounds of the three authors with Wells focusing on issues of ontology and the affective domain. Mercer and Smardon focus on issues of identity and the role of dialog. Hewson's, Vosniadou's and Tiberghien's responses to Roth, Lee and Hwang offer robust critique of what appear to be exploratory ideas. To what extent the authors of the response papers enter into dialog with the papers is discussed. How far research into learning in science has progressed since the 1980s is examined.

By growing fatigue cracks on a {100} cleavage plane, the singularity strengths have been determined for both growing and stationary cracks under relatively plane stress and plane strain conditions. This has allowed a comparison to existing theoretical models. It is shown that the HRR singularity (Hutchinson, Rice and Rosengren, 1968) for stationary cracks is very good to within I μm of the crack tip and a hardening model for the growing crack (gao and hwang, Advances in Fracture Research, edited by D. Francois. 5th Int. Conf. on Fracture, Cannes, France, 2, 669, 1981) is surprisingly good. Other issues such as fracture criteria are discussed since strains greater than unity were measured at the crack tip in this relatively brittle material.

  17. A new methodology for water resources multicriteria decision making under uncertainty

    Science.gov (United States)

    Simonovic, Slobodan P.; Verma, Rakesh

    A multiciteria decision making problem in water resource is addressed through the generation of fuzzy Pareto optimal set. Methodology is using positive and negative ideal solutions (Lai, Y.-J., Liu, T.-Y., Hwang, C.L. (1994). TOPSIS for MODM. European Journal of Operational Research 76, 486-500) and a set of weights assigned to the objective functions in fuzzy triangular form. Solution of the problem is obtained by transforming each objective function into a set of three objective functions. A planning problem of multicriteria waste water treatment from the literature is used as an illustrative example to demonstrate the utility of the proposed methodology. The obtained fuzzy Pareto solution set has been compared with the deterministic solution set. It is shown that the proposed approach can: (a) capture the uncertainty associated with the assignment of weights; and (b) provide the decision makers with a wider range of solutions to select from.

  19. Remote sensing of hydrological connectivity

    Schultz, Colin

    2012-08-01

    The sub-surface flow of water within a watershed is traditionally thought to depend solely on topographic or physical influences, such as slope, soil permeability, and channel density. Though often overlooked, some researchers propose that the role of vegetation and its feedback on subsurface flow could be just as important in some cases. Plants tend to increase subsurface flow by increasing soil conductivity and preferential flow paths. They can also cause it to decline, as plants use subsurface water and nutrients to fuel their growth, drawing it out of the system through evapotranspiration. Both sets of feedbacks affect the downslope availability of water. To capitalize on this idea, Hwang et al. devised a system called the hydrological vegetation gradient (HVG).

    2006-08-24

    The onion-ring structure is validated in the Pd-Pt bimetallic clusters of total atom numbers 147 and 309 through the Monte Carlo method by using the second-moment approximation of the tight-binding (TB-SMA) potentials, which is conceived in predicting the possible structures of the bimetallic clusters by He et al. [J. Am. Chem. Soc. 2003, 125, 11034] and Hwang et al. [J. Am. Chem. Soc. 2005, 127, 11140]. In the onion-ring structure, Pd atoms and Pt atoms occupy alternate layers of the clusters. The formation of the onion-ring structure can be associated with the fact that the single Pt impurity is favorable to stay in the subsurface layer and the central part of bimetallic clusters.

  2. A Cryptosystem for Encryption and Decryption of Long Confidential Messages

    Giri, Debasis; Barua, Prithayan; Srivastava, P. D.; Jana, Biswapati

    In this paper, we propose a cryptosystem which can encrypt and decrypt long (text) messages in efficient manner. The proposed cryptosystem is a combination of symmetric-key and asymmetric-key cryptography, where asymmetric-key cryptography is used to transmit the secret key to an intended receiver and the sender/receiver encrypts/decrypts messages using that secret key. In 2002, Hwang et al. proposed a scheme for encrypting long messages. The main drawback of their scheme is that it requires more computational overhead. Our proposed scheme is more efficient from the computational point of view compared to that of their scheme. Our scheme is a block cipher, long messages are broken into fixed length plaintext blocks for encryption. It supports parallel computation, since encryption/decryption of all the blocks of plaintext/plaintext are independent and thus can be carried out simultaneously. In addition, our scheme retains the same security level as their scheme.

    Recently, Gao et al.'s [Commun. Theor. Phys. 52 (2009) 421] multiparty quantum secret sharing (MQSS) protocol with two-photon three-dimensional Bell states was enhanced by Hwang et al. [Commun. Theor. Phys. 56 (2011) 79]. The improved protocol removes some unnecessary unitary operations, devices, and transmissions by the technique of decoy single photons and careful modification. However, in this paper, we investigate the security of the improved protocol and find it is insecure. The eavesdropper can steal all Alice's secret information. Furthermore, a feasible modification to remedy the security loophole is put forward. Our improved protocol provides a basic method to modify a kind of MQSS protocols which cannot resist the collusion attack.

    @@ 1. Introduction A digraph G is called primitive if there exists a positive integer k such that there is a walk of length k from u to v for each ordered pair of not necessarily distinct vertices u and v. The smallest such k is called the exponent of G, denoted by γ(G). Exponents for primitive digraphs have been studied extensively due to their intrinsic importance in graph theory, combinatorics, matrix theory, and their applications in communication problems. As a generalization of exponents, Brualdi and Liu[1] introduced the concept of upper generalized exponents for primitive digraphs. Recently, Shao, Wu and Hwang[2'3] extended this concept of upper generalized exponents from primitive digraphs to general digraphs which are not necessarily primitive.

    Wei, L Y

    The theoretical foundation of Chinese medicine as laid down in Hwang Ti Nei Ching is presented and interpreted here in modern language and conception. Our attempt is to bring Chinese medicine in harmony with Western science. Three Yin-Yang laws are formulated based on I Ching and Nei Ching and are justified from physics, mathematics and biology. The Wu-Hsing dynamic model is explained on the basis of dynamic interactions rather than static elements. The Ching-Lo doctrine is stressed upon its apparent correlations with the autonomic nervous system. Finally, the Chi is taken to play a role in life as the fields (gravitational, magnetic, nuclear, etc.) do in the physical world.

  8. Note on a paradox in decision-theoretic interval estimation

    CERN Document Server

    Kabaila, Paul

    2012-01-01

    Confidence intervals are assessed according to two criteria, namely expected length and coverage probability. In an attempt to apply the decision-theoretic method to finding a good confidence interval, a loss function that is a linear combination of the interval length and the indicator function that the interval includes the parameter of interest has been proposed. We consider the particular case that the parameter of interest is the normal mean, when the variance is unknown. Casella, Hwang and Robert, Statistica Sinica, 1993, have shown that this loss function, combined with the standard noninformative prior, leads to a generalized Bayes rule that is a confidence interval for this parameter which has "paradoxical behaviour". We show that a simple modification of this loss function, combined with the same prior, leads to a generalized Bayes rule that is the usual confidence interval i.e. the "paradoxical behaviour" is removed.

Nevertheless, limited safety information is available for many NPs, especially in terms of their interactions with various binding proteins, leading to potential toxic effects. Zinc oxide (ZnO NPs are included in the formulation of new products, such as adhesives, batteries, ceramics, cosmetics, cement, glass, ointments, paints, pigments, and supplementary foods, resulting in increased human exposures to ZnO. Hence, we investigated the potential ZnO nanotoxic pathways by analyzing the adsorbed proteins, called protein corona, from blood and brain from four ZnO NPs, ZnOSM20(-, ZnOSM20(+, ZnOAE100(-, and ZnOAE100(+, in order to understand their potential mechanisms in vivo. Through this study, liquid chromatography–mass spectroscopy/mass spectroscopy technology was employed to identify all bound proteins. Totals of 52 and 58 plasma proteins were identified as being bound to ZnOSM20(- and ZnOSM20(+, respectively. For ZnOAE100(- and ZnOAE100(+, 58 and 44 proteins were bound, respectively. Similar numbers of proteins were adsorbed onto ZnO irrespective of size or surface charge of the nanoparticle. These proteins were further analyzed with ClueGO, a Cytoscape plugin, which provided gene ontology and the biological interaction processes of identified proteins. Interactions between diverse proteins and ZnO nanoparticles could result in an alteration of their functions, conformation, and clearance, eventually affecting many biological processes.

    Geiji-Bokryung-Hwan (GBH) was studied on antiplatelet activity in human platelet suspensions. GBH consists of the 5 herbs Cinnamomi Ramulus, Poria Cocos, Mountan Cortex Radicis, Paeoniae Radix, and Persicae Semen, which have been used in herbal medicine for thousands of years for atherosclerosis. The mechanism involved in the antiplatelet activity of GBH in human platelet suspensions was investigated. GBH inhibited platelet aggregation and Ca2+ mobilization in a concentration-dependent manner without increasing intracellular cyclic AMP and cyclic GMP. GBH had no inhibitory effect on thromboxane B2 (TXB2) production in cell-free systems. Collagen-related peptide (CRP)-induced Ca2+ mobilization is regulated by phospholipase C-2 (PLC-gamma2) activation. We evaluated the effect of GBH on tyrosine phosphorylation of PLC-gamma2 and the production of inositol-1,4,5-trisphosphate (IP3). GBH at concentrations that inhibited platelet aggregation and Ca2+ mobilization had no effects on tyrosine phosphorylation of PLC-gamma2 or on the formation of IP3 induced by CRP. Similar results were obtained with thrombin-induced platelet activation. GBH inhibited platelet aggregation and Ca2+ mobilization induced by thrombin without affecting the production of IP3. We then evaluated the effect of GBH on the binding of IP3 to its receptor. GBH at high concentrations partially blocked the binding of IP3 to its receptor. Therefore, the results suggested that GBH suppresses Ca2+ mobilization at a step distal to IP3 formation. GBH may provide a good tool for investigating Ca2+ mobilization.

Spherical composite nanoparticles with a mean size smaller than 400 nm, which contained valsartan, were successfully fabricated by using the SAS process. X-ray diffraction and thermal analyses indicated that valsartan was present in an amorphous form within the composite nanoparticles. The in vitro dissolution and oral bioavailability of valsartan were dramatically enhanced by the composite nanoparticles. Valsartan–hydroxypropyl methylcellulose–poloxamer 407 nanoparticles exhibited faster drug release (up to 90% within 10 minutes under all dissolution conditions and higher oral bioavailability than the raw material, with an approximately 7.2-fold higher maximum plasma concentration. In addition, there was a positive linear correlation between the pharmacokinetic parameters and the in vitro dissolution efficiency. Therefore, the preparation of composite nanoparticles with valsartan–hydroxypropyl methylcellulose and poloxamer 407 by using the SAS process could be an effective formulation strategy for the development of a new dosage form of valsartan with high oral bioavailability.Keywords: supersaturation, bioavailability, solid dispersion, dissolution, supercritical fluid

Poloxamer-based nanomicelles with thermosensitive and mucoadhesive properties were prepared using the cold method. The optimized nanomicellar formulation was evaluated in terms of physicochemical and viscoelastic parameters. Nanomicelles containing bile salt maintained sufficient gelation strength (234×102 mPa·s and mucoadhesive force (17.3×102 dyne/cm2 to be retained in the upper part of the rectum. They significantly enhanced the DCT internalization across the rectal mucosa and showed a high plasma level during the first 4 hours of the study period, compared to nanomicelles with no bile salt. As a result, a slightly higher rectal bioavailability of ~33% was observed in nanomicelles containing bile salt, compared to ~28% from the latter system. The higher pharmacokinetic parameters for rectally administered DCT/P407/P188/Tween 80/NaTC (0.25%/11%/15%/10%/0.1% by weight, respectively resulted in significant anti-tumor efficacy. However, the tumor regression rate for the NaTC group was not statistically different from that for nanomicelles without NaTC. Therefore, overall results suggest that thermosensitive nanomicelles could be a potential dosage form for improvement of the bioavailability and chemotherapeutic profile of DCT.

Cinacalcet effectively controls SHPT without causing hypercalcemia and hyperphosphatemia. However, there is significant inter-individual response variance to cinacalcet treatment. Therefore, we aimed to evaluate the genetic effects related with parathyroid hormone regulation as factors for cinacalcet response variance. Methods: Patients with a diagnosis of SHPT based on intact parathyroid hormone (iPTH >300 pg/mL on dialysis were included in this study. They were over 18 years and have been treated by cinacalcet for more than 3 months. Responders and nonresponders were grouped by the serum iPTH changes. Twenty-four single nucleotide polymorphisms of CASR, VDR, FGFR1, KL, ALPL, RGS14, NR4A2, and PTHLH genes were selected for the pharmacogenetic analysis. Results: After adjusting for age, sex, and calcium level, CASR rs1042636 (odds ratio [OR]: 0.066, P=0.027 and rs1802757 (OR: 10.532, P=0.042 were associated with cinacalcet response.

Conclusion: We obtained supporting information of the associations between cinacalcet response and CASR polymorphisms. CASR single nucleotide polymorphisms (SNPs rs1802757, rs1042636, and haplotypes of rs1042636, rs10190, and rs1802757 were significantly associated with cinacalcet response variance.

ALA-only displayed marginal cytotoxicity; ALA-PVA nanofiber showed less cytotoxicity. PpIX generation was not sigficantly different between ALA and ALA-PVA nanofiber treatments. PVA itself did not generate PpIX in tumor cells. ALA and ALA-PVA nanofiber displayed a similar PDT effect on tumor cells. Cell viability was decreased, dose-dependently, until ALA concentration reached 100 µg/mL. Necrosis and apoptosis of tumor cells occurred similarly for ALA and ALA- PVA nanofiber treatments.Conclusion: The ALA-PVA nanofiber-coated stent is a promising candidate for therapeutic use with cholangiocarcinoma.Keywords: nanofiber, photodynamic therapy, 5-aminolevulinic acid, poly(vinyl alcohol

In this study, we entrapped curcumin into monoolein (MO-based liquid crystalline nanoparticles (LCNs and evaluated the physicochemical properties and anticancer activity of the LCN dispersion. The results revealed that particles in the curcumin-loaded LCN dispersion were discrete and monodispersed, and that the entrapment efficiency was almost 100%. The stability of curcumin in the dispersion was surprisingly enhanced (about 75% of the curcumin survived after 45 days of storage at 40°C, and the in vitro release of curcumin was sustained (10% or less over 15 days. Fluorescence-activated cell sorting (FACS analysis using a human colon cancer cell line (HCT116 exhibited 99.1% fluorescence gating for 5 µM curcumin-loaded LCN dispersion compared to 1.36% for the same concentration of the drug in dimethyl sulfoxide (DMSO, indicating markedly enhanced cellular uptake. Consistent with the enhanced cellular uptake of curcumin-loaded LCNs, anticancer activity and cell cycle studies demonstrated apoptosis induction when the cells were treated with the LCN dispersion; however, there was neither noticeable cell death nor significant changes in the cell cycle for the same concentration of the drug in DMSO. In conclusion, entrapping curcumin into MO-based LCNs may provide, in the future, a strategy for overcoming the hurdles associated with both the stability and cellular uptake issues of the drug in the treatment of various cancers.

    Full Text Available The piriform fossae are the 2 pear-shaped cavities lateral to the laryngeal vestibule at the lower end of the vocal tract. They act acoustically as side-branches to the main tract, resulting in a spectral zero in the output of the human voice. This study investigates their spectral role by comparing numerical and experimental results of MRI-based 3D printed Vocal Tracts, for which a new experimental method (based on room acoustics is introduced. The findings support results in the literature: the piriform fossae create a spectral trough in the region 4-5 kHz and act as formants repellents. Moreover, this study extends those results by demonstrating numerically and perceptually the impact of having large piriform fossae on the sung output.

    Full Text Available Der Philosoph Harald Lemke stellt in seinem neuen Buch "Politik des Essens. Wovon die Welt von morgen lebt" der Philosophie die Aufgabe, sich mit dem Welthungerproblem zu beschäftigen und eine Lösung für dieses zu finden. Dabei wirft er die zentrale Leitfrage auf, was jeder Einzelne tun kann und sollte, um ein faires, nachhaltiges und biologisches Weltagrarsystem zu fördern und so der Hungerproblematik ein Ende zu setzen. Lemke führt in diesem Zusammenhang die Begriffe der Gastrosophie und der Gastroethik ein. Die Gastrosophie beschäftigt sich als Philosophie des Essens mit der Produktion, dem Handel und dem Endverbrauch von Nahrungsmitteln. Die Gastroethik soll Maximen eines ethisch guten Konsums festlegen.

    Full Text Available When relating his journey, Friar Diego de Ocaña describes two festivities celebrated in Villa de Potosí, both dedicated to the enthronement of images of the Virgin painted by himself. The festivities included processions as well as literary pieces to honor the Virgin. Ocaña notes that among the poetic texts composed in veneration and praise of the Virgin, there were also prayer-like compositions that were sung during the processions, at the end of the Eucharistic celebration, during the Salve Regina, or during those moments when the image was placed upon the altar. In the present article particular attention is given to various texts, specifically to those which accompanied the festivities that took place with the same pomp and circumstance as those ceremonies celebrated for the feast of Corpus Christ.

    Fifteen professional singers sang simple vocal exercises at different pitches. The sung excerpts were recorded, and seven modified versions were created from each recording. The modifications were then played to the participant and (s)he had to assess the similarity of these stimuli to the perception of his/her own voice during the act of singing. Participants rated as most similar those stimuli which were modified by the filter whose frequency response most closely resembled a trapezoid, which was created by taking into account 1) the diffracting air conduction component from the mouth of the singer to his ear channel, 2) the bone conduction component, and also 3) the influence of the stapedius reflex on the sensitivity of his/her auditory system.

    Pfordresher, Peter Q; Halpern, Andrea R

    2013-08-01

    The vocal imitation of pitch by singing requires one to plan laryngeal movements on the basis of anticipated target pitch events. This process may rely on auditory imagery, which has been shown to activate motor planning areas. As such, we hypothesized that poor-pitch singing, although not typically associated with deficient pitch perception, may be associated with deficient auditory imagery. Participants vocally imitated simple pitch sequences by singing, discriminated pitch pairs on the basis of pitch height, and completed an auditory imagery self-report questionnaire (the Bucknell Auditory Imagery Scale). The percentage of trials participants sung in tune correlated significantly with self-reports of vividness for auditory imagery, although not with the ability to control auditory imagery. Pitch discrimination was not predicted by auditory imagery scores. The results thus support a link between auditory imagery and vocal imitation.

    A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers. The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order better to understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (n = 50) participated in the study. The analytical method described in the reference paper has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices.

    Full Text Available Faith embodied – Aspects of the authentic communication of the faith In this article a theological theory for the communication of the faith is addressed from the basic metaphor of the Church as the body of Christ, within the fields of church publications, visual communication, the worship service and church music. It is argued that words (spoken, published or sung, music, art, gestures, visual images, silences and open spaces, are all communicative actions performing on a symbolic or metaphorical level to express and communicate the faith. Through these communicative actions the corporate identity of the community of faith is shaped and the body of Christ is built up. It is argued that in the church the act of communicating should adhere to certain theological principles to be true to its essence and aim: to communicate the faith faithfully and trustworthy.

    Full Text Available Word-learning likely involves a multiplicity of components, some domain-general, others domain-specific. Against the background of recent studies that suggest that word-learning is domain-specific, we investigated the associative component of word-learning. Seven- and 14-month-old infants viewed a pair of events in which a monkey or a truck moved back and forth, accompanied by a sung syllable or a tone, matched for pitch. Following habituation, infants were presented with displays in which the visual-auditory pairings were preserved or switched, and looked longer at the switch events when exposure time was sufficient to learn the intermodal association. At 7 months, performance on speech and tones conditions was statistically identical; at 14 months, infants had begun to favor speech. Thus, the associative component of word-learning does not appear (in contrast to rule-learning, Marcus et al., 2007 to initially privilege speech.

    Sung, Y C; Fuchs, J A

    1989-09-01

    Escherichia coli contains an inducible enzyme, cyanase, that catalyzes the decomposition of cyanate into ammonia and bicarbonate. The gene encoding cyanase, cynS, was cloned and found to be on a DNA fragment that contained the lac operon. Characterization of a plasmid encoding cyanase indicated that a 26-kilodalton (kDa) protein of unknown function was also induced by cyanate (Y-C. Sung, D. Parsell, P.M. Anderson, and J.A. Fuchs, J. Bacteriol. 169:2639-2642, 1987). The gene encoding the 26-kDa protein was located between cynS and its promoter, indicating the existence of a cyn operon. The 26-kDa protein was identified as a cyanate permease that transports exogenous cyanate by active transport. E. coli was shown to contain a cyanate transport system that is energy dependent and saturable by cyanate.

    2013-01-01

    Levitin's findings that nonmusicians could produce from memory the absolute pitches of self-selected pop songs have been widely cited in the music psychology literature. These findings suggest that latent absolute pitch (AP) memory may be a more widespread trait within the population than traditional AP labelling ability. However, it has been left unclear what factors may facilitate absolute pitch retention for familiar pieces of music. The aim of the present paper was to investigate factors that may contribute to latent AP memory using Levitin's sung production paradigm for AP memory and comparing results to the outcomes of a pitch labelling task, a relative pitch memory test, measures of music-induced emotions, and various measures of participants' musical backgrounds. Our results suggest that relative pitch memory and the quality and degree of music-elicited emotions impact on latent AP memory.

    Nach der weit reichenden Etablierung von eLearning in den letzten Jahren stehen nahezu alle deutschen Hochschulen vor der Aufgabe, wettbewerbsfähige hochschulübergreifende Mechanismen sowie entsprechende organisatorische Rahmenbedingungen zu schaffen. Vor allem die Umsetzung von EBologna und die Unterstützung kooperativer Bildungsangebote verstärken diese Notwendigkeit. Motiviert durch die Veränderungen im Bereich der Hochschullehre und die Herausforderungen für künftige Lernumgebungen schlagen wir eine Integrationslösung im Sinne eines Learning Gateway vor, die zur webgestützten Abwicklung von kooperativen Bildungsangeboten in heterogen Lernumgebungen eingesetzt werden kann. Ihre Praxisanwendung verdeutlichen wir anschließend im komplexen Szenario der Medizin an der TUM. Die Evaluierung der Umsetzung belegt den deutlichen Mehrwert des Ansatzes.

    Full Text Available Architectural schools extend ideology unknowingly. We have lost the primary sources essential to architectural thinking and making, that is a means of grasping, intellectually ad imaginatively, the small, evanescent details that reveal a fleeting truth. Architecture educators have allowed architecture and design to develop separately. The ideological construct of a scale through which we distinguish a building from its landscape, sublets the fractal nature of cities, which is a conversion of outer to inner — a matter of “emergence” rather than causal chains. The city embodies the human essence, the will to exist not just in the face of, but also through self-destruction. Architecture’s origins are in the shamanistic construction of fissures that allow us to make shadows to be measured with a precise musical geometry and sung to create the Real of the world.

    2011-08-01

    This paper compared the specificity of recollections of autobiographical memories where musical cues for events were varied. We used music which was popular in the past as cues which were related to a larger number of past individual events (frequent events cues) and music which was typically only sung at graduation ceremonies as cues which were related to a smaller number of events (rare events cues). In the instructed retrieval condition, participants were told to listen to the music and to recall past events, whereas in incidental retrieval condition, the instruction was only to listen to the music. Then participants were asked to describe what they recalled while hearing the music. When frequent events musical cues were played, the specificities of the recalled events were higher in the instructed retrieval condition than in the incidental retrieval condition. In contrast, when rare events musical cues were played, there were no differences in the specificities of the recalled events.

    Full Text Available The Greek drama can be apprehended as an extended ritual, originating in the ceremonies of the Dionysus cult. In particular, tragedy derived its origin from the sacrifice of goats and the hymns which were sung on that occasion. Tragedia means "song of the male goat" and these hymns later developed into choruses and eventually into tragedy, in the sense of a solemn and purifying drama. The presence of the god Dionysus is evident in the history and development of the Greek drama at the beginning of the fifth century B.C. and its sudden decline 150 years later. Its rise seems to correspond with the Greek polis, where questions of justice and divine law in conflict with the individual were obviously a matter of discussion and where the drama had individual and collective catharsis (purifying in mind.

The rich water-sources facilitated the development of gastronomy, agriculture, trade and administration, especially after it became the capital of the Southern Sung Dynasty. Hangzhou's food sources are especially diverse, notably for fish, green vegetables, fungi, and tofu, and have been since early records. As capital, it became a leader in cuisine, and in the development of the restaurant industry. The strength of food traditions has been reinforced constantly by the cultural, medicinal, nutritional, and social values of food and cooking, by the interest of Chinese scholars in food and wine, and by the narrative that accompanies specific dishes.

    Full Text Available Syingir is a advice poem that uses the daily Javanese Language and sung individually or together. Syingir developed in pesantren [lslamic boarding school] or in Islamic region, in Central Java and East Java. The creators are kyai or da'i. This poem created to spread the teachings of Islam including akidah, syariah, and muamalah by means of an easy to remember so it was easy to be understood. In terms of firm, syingir closer to the pattern of traditional Arabic poem, syi'ir known as the pattern of al-Khalil. Usage that pattern was caused by penyingir are kiais that had been familiar with ilmul arudl wal-'-qafiyah, the science of rhythm and rhyme in Arabic poetry. While in the term of content, syingir as a religious message is the transformation of the contents of the Arabic poetry which is at-ta'lim (education.

    Full Text Available The decision to speak Catalan to my daughter came naturally to me. How else would I tell a story, sing a lullaby or make her laugh but in the language I was told stories, sung lullabies to and made to laugh since I was a new-born! However, whereas the choice to speak one’s mother tongue to your children is not questioned anymore in Spain, making this same choice when you live elsewhere seems to raise a lot of eyebrows. In this article I will reflect, from my own experience, on speaking a language of Spain other than Spanish in Australia. Catalan is one of 300 community languages in Australia, and it’s spoken by a small and ageing population.

    Full Text Available In oral folk song traditions we often find many lyrics, but not nearly as many melodies. The terms “polyfunctionalism”, “group melodies” or “general melodies” have been used by Estonian researches to indicate the phenomenon that many lyrics were sung to only one, or a small handful, of tunes. The scarcity of melodies is supposed to be one of several related phenomena characteristic to an oral, text-centred singing culture.In this article the Estonian folk song tradition will be analysed against a quantity of melodies and their usage in the following aspects: word-and-melody relationships and context-and-melody relationships in Karksi parish (south Estonia; a singer; and native musical terms and the process of singing and (recreation.

    AlGaAs/GaAs multi-quantum well (MQW) was prepared by molecular beam epitaxy(MBE) with growth-interrupted heterointerface (GIH) method and continuous growth (CG) method,respectively. The microstructures of the MQWs were characterized by double-crystal X-ray rocking curve (DCRC) and atomic force microscopy (AFM),and the photoluminescence (PL) properties of the MQWs were also studied. The MQWs grown with GIH method show that higher order satellite peaks of Pendell(o)sung fringes are observed in DCRC,the roughness of surface is much reduced in AFM,and the full width at half maximum (FWHM) of exciton line is much narrower in PL. The results indicate that the GIH method reduces the monolayer growth step density at the heterointerface due to the migration of surface atoms for a few minutes growth interruption,and substantially improves the quality of AlGaAs/GaAs MQWs.

  2. EEG correlates of song prosody: A new look at the relationship between linguistic and musical rhythm

    Full Text Available Song composers incorporate linguistic prosody into their music when setting words to melody, a process called textsetting. Composers tend to align the expected stress of the lyrics with strong metrical positions in the music. The present study was designed to explore the idea that temporal alignment helps listeners to better understand song lyrics by directing listeners’ attention to instances where strong syllables occur on strong beats. Three types of textsettings were created by aligning metronome clicks with all, some or none of the strong syllables in sung sentences. Electroencephalographic (EEG recordings were taken while participants listened to the sung sentences (primes and performed a lexical decision task on subsequent words and pseudowords (targets, presented visually. Comparison of misaligned and well-aligned sentences showed that temporal alignment between strong/weak syllables and strong/weak musical beats were associated with modulations of induced beta and evoked gamma power, which have been shown to fluctuate with rhythmic expectancies. Furthermore, targets that followed well-aligned primes elicited greater induced alpha and beta activity, and better lexical decision task performance, compared with targets that followed misaligned and varied sentences. Overall, these findings suggest that alignment of linguistic stress and musical meter in song enhances musical beat tracking and comprehension of lyrics by synchronizing neural activity with strong syllables. This approach may begin to explain the mechanisms underlying the relationship between linguistic and musical rhythm in songs, and how rhythmic attending facilitates learning and recall of song lyrics. Moreover, the observations reported here coincide with a growing number of studies reporting interactions between the linguistic and musical dimensions of song, which likely stem from shared neural resources for processing music and speech.

    We investigated music and language processing in a group of early bilinguals who spoke a tone language and a non-tone language (Cantonese and Dutch). We assessed online speech-music processing interactions, that is, interactions that occur when speech and music are processed simultaneously in songs, with a speeded classification task. In this task, participants judged sung pseudowords either musically (based on the direction of the musical interval) or phonologically (based on the identity of the sung vowel). We also assessed longer-term effects of linguistic experience on musical ability, that is, the influence of extensive prior experience with language when processing music. These effects were assessed with a task in which participants had to learn to identify musical intervals and with four pitch-perception tasks. Our hypothesis was that due to their experience in two different languages using lexical versus intonational tone, the early Cantonese-Dutch bilinguals would outperform the Dutch control participants. In online processing, the Cantonese-Dutch bilinguals processed speech and music more holistically than controls. This effect seems to be driven by experience with a tone language, in which integration of segmental and pitch information is fundamental. Regarding longer-term effects of linguistic experience, we found no evidence for a bilingual advantage in either the music-interval learning task or the pitch-perception tasks. Together, these results suggest that being a Cantonese-Dutch bilingual does not have any measurable longer-term effects on pitch and music processing, but does have consequences for how speech and music are processed jointly.

    Songs naturally bind lyrics and melody into a unified representation. Using a subsequent memory paradigm, we examined the neural processes associated with binding lyrics and melodies during song encoding. Participants were presented with songs in two conditions: a unified condition (melodies sung with lyrics), and a separate condition (melodies sung with the syllable "la"). In both cases, written lyrics were displayed and participants were instructed to memorize them by repeating them covertly or by generating mental images of the songs. We expected the unified condition to recruit the posterior superior temporal gyrus, known to be involved in perceptual integration of songs, as well as the left inferior frontal gyrus (IFG). Conversely, we hypothesized that the separate condition would engage a larger network including the hippocampus to bind lyrics and melodies of songs, and the basal ganglia and the cerebellum to ensure the correct sequence coupling of verbal and musical information in time. Binding lyrics and melodies in the unified condition revealed activation of the left IFG, bilateral middle temporal gyrus (MTG), and left motor cortex, suggesting a strong linguistic processing for this condition. Binding in the separate compared to the unified condition revealed greater activity in the right hippocampus as well as other areas including the left caudate, left cerebellum, and right IFG. This study provides novel evidence for the role of the right hippocampus in binding lyrics and melodies in songs. Results are discussed in light of studies of binding in the visual domain and highlight the role of regions involved in timing and synchronization such as the basal ganglia and the cerebellum.

Musical notation, and musical and linguistic characteristics of a Chinese-Huzhu Mongghul bilingual song in the Fulaan Nara dialect of Huzhu Mongghul are given. Huzhu Mongghul is an endangered language of the Monguor (Tu subgroup of the Mongolic language family, spoken in the provinces of Qinghai and Gansu in the People's Republic of China (Faehndrich 2007. The official Chinese name for the Monguor language is Tuzuyu. The Fulaan Nara dialect of Huzhu Mongghul is spoken in Wushi, Hongyazigou, and Songduo townships in Huzhu Mongghul Autonomous County and in Dala Township, Ledu County, which are all located in Haidong Municipality, Qinghai Province. Most speakers of Fulaan Nara are bilingual in the local variety of Chinese (Qinghaihua; see Dede 2003. Young people also speak Modern Standard Chinese, many of them fluently, depending on the amount of schooling they have received. This widespread bilingualism is expressed in the song described here, which alternates between the Qinghai Chinese dialect and Huzhu Mongghul. Bilingualism in Mongghul song has previously been discussed by Qi (2007:66-76, including excerpts of the song described here, as well as other bilingual Huzhu Mongghul songs (both Mongghul-Chinese and Mongghul-Tibetan. In addition to Mongghul and Chinese, a small number of people also speak Tibetan; mostly those who have learned it in school as a second language. Levy met only one male speaker, born in about 1935, who spoke Tibetan without having learned it in school. In spite of the few people who are genuinely bilingual (or trilingual, certain Mongghul songs (mostly wedding songs are sung in Tibetan. Qi (1997 and Qi et al.

    Full Text Available This paper analyzes the role of mediators in the resolution of the Aceh conflict within the framework of a three-step process. Two separate mediation efforts, one conducted by the Centre for Humanitarian Dialogue from 1999 until 2003 and a second one led by Martti Ahtisaari and his Crisis Management Initiative in 2004/2005, attempted to solve the Aceh confl ict. The author shows that beside contextual factors such as ripeness of the conflict and advantageous relations between and characteristics of the conflict parties, the success of Ahtisaari’s engagement can be further explained by procedural factors. These include mediator behaviour and mediation strategies. Furthermore the mediator’s ability to use contacts with official track one actors was crucial in securing the signing as well as the implementation of the present peace agreement. ----- Der Artikel analysiert die Rolle von Mediatoren in der Lösung des Aceh Konfl ikts mittels eines drei-Phasen Modells von Konfliktlösung. Zwei voneinander unabhängige Mediationsverfahren, jenes des Centre for Humanitarian Dialogue von 1999 bis 2003, und ein weiteres geleitet durch Martti Ahtisaari und seiner Crisis Management Initiative in 2004/2005, zielten darauf ab den Konflikt zu lösen. Der Autor zeigt, dass neben kontextuellen Faktoren wie einer “ripeness” des Konflikts sowie günstigen Veränderungen auf Seite der Konfliktparteien, prozedurale Faktoren für den Erfolg Ahtisaaris entscheidend waren. Diese Faktoren beziehen sich auf das Agieren und die Strategien des Mediators. Die Fähigkeit des Mediators, Kontakte zu offiziellen “track one” Akteuren aktiv während des Mediationsprozesses zu nutzen, bildete einen Schlüsselfaktor darin einen Friedensschluss und im weiteren Verlauf eine weitgehend erfolgreiche Umsetzung des aktuellen Abkommens zwischen den ehemaligen Konfliktparteien zu erreichen.

    Understanding the processes driving the carbon cycle in the Arctic Ocean is of fundamental importance for assessing the impacts of the predicted climate change in this critical region. We analyzed sinking particle samples intercepted below the marginal ice zone of the Beaufort Sea at a depth of 3067m (Station A, 75N, 150W) in the Canada Basin from 2004 to 2005 and from 2007 to 2009, in order to examine interannual variability in carbon export to the bathypelagic zone. Sinking particles were also collected at other depths-2000m and 3750m- at Station A and from other locations (Station B-78N, 150W, and Station D-74N, 140W) within the basin for the latter time period. Prior observations from the 2004-5 study revealed that mass flux variations were temporally decoupled from the cycle of primary productivity in surface waters, and that sinking particle composition was characterized by old organic carbon (mean 14C age = ~ 1900 14C years) and abundant lithogenic material (~80%), implying supply via lateral advection from the surrounding margins (Hwang et al., 2008). Observations at Station A from 2007-9 reveal a similar mode of particle supply suggesting that lateral advection of resuspended sediment is a persistent feature in the southwest Canada Basin. Particle fluxes at three depths at Station A were similar with only slightly higher values at 50 m above the bottom, implying that lateral transport occurs throughout the lower water column. Particle flux and Δ14C values exhibited a negative correlation. Particle flux and Δ14C results also reveal interannual variability and spatial heterogeneity. A marked particle flux maximum was observed at Station A in August 2008 that was not seen in the prior deployments of 2004 and 2007. Extremely low Δ14C values for this late summer flux maximum implies that sediment resuspension and lateral advection, instead of enhanced summer time primary production in the overlying water column, was responsible. Particle flux was the highest

    The aim of this study is to see which brow archetype is preferred by Korean women. The archetypes were chosen from a literature search, which contain detailed, replicable methods and have diagrams (Westmore, Lamas, Anastasia, Schreiber, and Hwang). A survey was conducted on 300 subjects (group A, 100 female medical students; group B, 100 women who had visited a plastic surgery clinic for periorbital rejuvenation; and group C, 100 women who visited the brow bar). They were asked whether they think there might be a method that yields an ideal brow archetype. In the cases where they said yes, they were asked to choose 1 of the illustrated 5 brow archetypes that they think is ideal. Among the 300 respondents, 232 (77.3%) thought there might be a method to yield an ideal brow archetype, whereas 68 (22.7%) answered they did not. The preference for the brow archetypes was different among the 5 archetypes (P = 0.0001, χ2). Anastasia was the most preferred (44.8%, brow starts on a perpendicular line drawn from the middle of the nostril, arches on a line drawn from the center of the nose through the center of the pupil, and ends on a line drawn from the edge of the corresponding nasal ala through the outer edge of the eye). Anastasia was followed by Lamas (22.0%). In group A, Anastasia (55.7%) was the most preferred, followed by Lamas (26.2%) and Westmore (13.1%). In group B, Anastasia (34.8%) was the most preferred, followed by Lamas (30.3%) and Westmore and Schreiber (both 13.5%). In group C, Anastasia (47.6%) was the most preferred, followed by Hwang (25.5%) and Westmore (11.0%). There was a significant difference (P archetype and occupation (P = 0.0033). However, no significant differences were noted for the preference of brow archetype between the age groups of younger than 30 years and older than 30 years (P = 0.1374), level of education (P = 0.3403), marital status (P = 0.541), or monthly income (P = 0.1696, χ2).

The molecular mechanism of statin-stimulated osteogenesis is unknown. Activation of RhoA signaling increases cytoskeletal tension, which plays a crucial role in the osteogenic differentiation of mesenchymal stem cells. We thus hypothesized that RhoA signaling is involved in simvastatin-induced osteogenesis in bone marrow mesenchymal stem cells. We found that although treatment with simvastatin shifts localization of RhoA protein from the membrane to the cytosol, the treatment still activates RhoA dose-dependently because it reduces the association with RhoGDIα. Simvastatin also increased the expression of osteogenic proteins, density of actin filament, the number of focal adhesions, and cellular tension. Furthermore, disrupting actin cytoskeleton or decreasing cell rigidity by using chemical agents reduced simvastatin-induced osteogenic differentiation. In vivo study also confirms that density of actin filament is increased in simvastatin-induced ectopic bone formation. Our study is the first to demonstrate that maintaining intact actin cytoskeletons and enhancing cell rigidity are crucial in simvastatin-induced osteogenesis. The results suggested that simvastatin, which is an

Developing new strategies to improve the osteoinductive activity of bone graft substitutes is both critical and practical for clinical application. Previously, we developed novel simvastatin-encapsulating poly(lactic-co-glycolic acid microspheres (SIM/PLGA that slowly release simvastatin and enhance fracture healing. In this study, we combined SIM/PLGA with a rapidly absorbable calcium sulfate (CS bone substitute and studied the effect on bone healing in critical-sized calvarial bone defects in a rat model. The cytotoxicity and cytocompatibility of this combination was tested in vitro using lactate dehydrogenase leakage and a cell attachment assay, respectively. Combination treatment with SIM/PLGA and the CS bone substitute had no cytotoxic effect on bone marrow stem cells. Compared with the control, cell adhesion was substantially enhanced following combination treatment with SIM/PLGA and the CS bone substitute. In vivo, implantation of the combination bone substitute promoted healing of critical-sized calvarial bone defects in rats; furthermore, production of bone morphogenetic protein-2 and neovascularization were enhanced in the area of the defect. In summary, the combination of SIM/PLGA and a CS bone substitute has osteoconductive and osteoinductive properties, indicating that it could be used for regeneration

Methods: The anticancer activity of streptochlorin was evaluated in vitro in various cholangiocarcinoma cell lines for apoptosis, proliferation, invasiveness, and expression of various protein levels. A liver metastasis model was prepared by splenic injection of HuCC-T1 cholangiocarcinoma cells using a BALB/c nude mouse model to study the systemic antimetastatic efficacy of streptochlorin 5 mg/kg at 8 weeks. The antitumor efficacy of subcutaneously injected streptochlorin was also assessed using a solid tumor xenograft model of SNU478 cells for 22 days in the BALB/c nude mouse. Results: Streptochlorin inhibited growth and secretion of vascular endothelial growth factor by cholangiocarcinoma cells in a dose-dependent manner and induced apoptosis in vitro. In addition, streptochlorin effectively inhibited invasion and migration of cholangiocarcinoma cells. Secretion of vascular endothelial growth factor and activity of matrix metalloproteinase-9 in cholangiocarcinoma cells were also suppressed by treatment with streptochlorin. Streptochlorin effectively regulated metastasis of HuCC-T1 cells in a mouse model of liver metastasis. In a tumor xenograft study using SNU478 cells, streptochlorin significantly inhibited tumor growth without changes in body weight

The aim of this study was to examine the effectiveness of a health coaching self-management program for older adults with multimorbidity in nursing homes. Methods: Older adults with multimorbidity from one nursing home in Korea were randomly allocated to either an intervention group (n=22 or conventional group (n=21. Participants in the intervention group met face to face with the researchers twice a week for 8 weeks, during which time the researchers engaged them in goal setting and goal performance using the strategies in the health coaching self-management program. Regular care was provided to the other participants in the conventional group. Results: Participants in the intervention group had significantly better outcomes in exercise behaviors (P=0.015, cognitive symptom management (P=0.004, mental stress management/relaxation (P=0.023, self-rated health (P=0.002, reduced illness intrusiveness (P<0.001, depression (P<0.001, and social/role activities limitations (P<0.001. In addition, there was a significant time-by-group interaction in self-efficacy (P=0.036. According to the goal attainment scales, their individual goals of oral health and stress reduction were achieved.Conclusion: The health coaching self-management program was successfully implemented in older adults with multimorbidity in a nursing home. Further research is needed to develop and evaluate the long-term effects of an intervention to enhance adherence to self-management and quality of life for older adults with multimorbidity.Keywords: chronic diseases, nursing intervention, older adults

It is ingested as an oral prodrug that is rapidly metabolized by carboxylesterase 1 (CES1 to its active form, oseltamivir carboxylate. Dexamethasone is also used in the treatment of acute respiratory distress syndrome, a severe complication of influenza; however, its influence on the pharmacokinetics (PK of oseltamivir is controversial. The aim of this study was to investigate the effects of coadministering oseltamivir and dexamethasone on the PK of oseltamivir in healthy volunteers. Methods: An open-label, two-period, one-sequence, multiple-dose study was conducted in 19 healthy male volunteers. Oseltamivir (75 mg was orally administered on Day 1 and Day 8, and dexamethasone (1.5 mg was administered once daily from Day 3 to Day 8. Serial blood and urine samples were collected for PK analysis of oseltamivir and oseltamivir carboxylate on Day 1 and Day 8. Oseltamivir and oseltamivir carboxylate concentrations in plasma and urine were determined using liquid chromatography–tandem mass spectrometry. Results: Area under the plasma concentration–time curve (AUC of oseltamivir and oseltamivir carboxylate decreased after dexamethasone treatment for 6 days.

All groups were fed the diet and water ad libitum for 14 weeks.Results: NOC reduced the body weight and adipose tissue mass, whereas OC did not. OC and NOC reduced mRNA levels of adipogenic genes, including peroxisome proliferator-activated receptor (PPAR-γ, sterol regulatory element-binding protein-1c, and fatty acid-binding protein in white adipose tissue. The mRNA levels of genes related to β-oxidation or thermogenesis including PPAR-α, palmitoyltransferase-1α, and uncoupling protein-2 were increased by the OC and NOC relative to the HF group. Both OC and NOC clearly stimulated AMP-activated protein kinase (AMPK activity. In particular, PPAR-α, palmitoyltransferase-1α, uncoupling protein-2 expression, and AMPK activity were significantly increased in the NOC group compared to in the OC group. NOC decreased glycerol-3-phosphate dehydrogenase activity whereas OC did not.Conclusion: From these results, NOC could be suggested as a potential anti-obesity agent in obese rats fed a HF diet. The effects of the NOC on obesity were associated with changes of multiple gene expression, activation of AMPK, and inhibition of glycerol-3-phosphate dehydrogenase in white adipose tissue.Keywords: oleoresin capsicum
