Manipulating excited state hyperfine level populations in an atomic laser through electronic spin polarization: controlling upper laser level degeneracy and small signal gain
Authors: Mironov A. E. , Eden J. G.
Published: November 2017

Anisotropic coherent radiation has been generated from an isotropic medium, in the absence of an external magnetic field, by the spin polarization of an atomic excited state. Lasing on specific hyperfine lines of the6p2P32→6s2S12(D2) transition of Cs at 852.1 nm has been realized by photoexciting Cs-rare gas thermal collision pairs with a circularly-polarized (σ+) optical field. Subsequent dissociation of the transient Cs-rare gasB2Σ12+diatomic molecule selectively populates theF= 4, 5 hyperfine levels of theCs 6p2P32state. Not only does electronic spin polarization of the upper laser level yield circularly-polarized coherent emission, but the effective degeneracy (g2) of the6p2P32state is altered by the non-statistical hyperfine state population distribution, thereby permitting control of the laser small signal gain with an elliptically-polarized pump optical field. TheD2laser efficiency and output power correlate directly with the molecular orbital structure of the Cs-rare gasB2Σ+state in the region of internuclear separation at which the diatomic complex is born.

BACKGROUND

Blockade of the renin–angiotensin system (RAS) represents a main strategy in the therapy of heart failure with reduced ejection fraction (HFrEF), but the role of active renin concentration (ARC) for guiding therapy in the presence of an RAS blockade remains to be established. This study assessed angiotensin profiles of HFrEF patients with distinct RAS activations as reflected by ARC.

METHODS

Two cohorts of stable chronic HFrEF patients on optimal medical treatment (OMT) were enrolled. We assessed ARC and all known circulating angiotensin metabolites, including AngI and AngII, by mass spectrometry to investigate the effect of different therapy modalities. Low- and high-renin HFrEF patients were identified by ARC screening and subsequently characterized by their angiotensin profiles.

RESULTS

Although different modes of RAS blockade resulted in typical AngII/AngI ratios, concentrations of (AngI+AngII) strongly correlated with ARC [r = 0.95, P < 0.001] independent of therapy mode. Despite RAS blocker treatment with angiotensin-converting enzyme inhibitors (ACE-I) or angiotensin II type 1 receptor blockers (ARB), which anticipated ARC upregulation, about 30% of patients showed lower/normal range ARC values. ARC did not correlate with N-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations and New York Heart Association (NYHA) stages. Angiotensin concentrations were profoundly diminished for the low-ARC group compared with the high-ARC group: AngI [6.4 ng/L (IQR: 2.1–12.5) vs 537.9 ng/L (IQR: 423.1–728.4), P < 0.001 for ACE-I; and 4.5 ng/L (IQR: 1.4–11.2) vs 203.0 ng/L (IQR: 130.2–247.9), P = 0.003 for ARB] and AngII [<1.4 ng/L (IQR: <1.4–1.5) vs 6.1 ng/L (IQR: 2.0–11.1), P = 0.002 for ACE-I and 4.7 ng/L (IQR: <1.4–12.3) vs 206.4 ng/L (IQR: 142.2–234.4), P < 0.001 for ARB].

CONCLUSIONS

In addition to NT-proBNP and NYHA stages, ARC enables classification of HFrEF patients receiving OMT into more distinguished neurohumoral HFrEF phenotypes, offering a rationale for adaptive therapeutic interventions.
PAPR reduction for FBMC/OQAM using hybrid scheme of different Precoding transform and mu-law companding
Authors: Shaheen Imad , Zekry Abdelhalim , Newagy Fatma , Ibrahim Reem
Published: November 2017

The filter banks multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) is developing multicarrier modulation technique used in the next wireless communication system (5G). FBMC/OQAM supports high data rate and high band width efficiency. However, one of the major drawbacks of FBMC system is high peak to Average Power Ratio (PAPR) of the transmitted signal, which causes serious degradation in performance of the system. Therefore, it is required to use a proper PAPR scheme at the transmitter to reduce the PAPR. In this paper, a hybrid scheme is investigated with the combination of preceding transform technique and Mu Law Companding technique to reduce PAPR in FBMC systems. Moreover, four preceding techniques are examined to find the best Precoding technique which can be used with Mu law commanding. We assessed the discrete Hartley transform (DHT). The discrete cosine transformed (DCT), the Discrete Sine Transform (DST), and the Walsh Hadamard transforms (WHT) which are applied separately with Mu Companding. The numerical results verify that the FBMC systems with all Precoding technique combined with Mu law commanding can improve PAPR performance of the signals greatly with the best results achieved when the combination scheme consists of the DST Precoding and Mu law commanding for both PAPR and BER performance.

Compresiones: política cultural, economía y mercado
Authors: Rojas Sotelo Miguel
Published: November 2017

ResumenEsta reflexión presenta en forma comprimida, y en cuatro entregas, el tiempo/espacio en la escena artística local moldeada por determinantes históricos de finales de siglo XX y principios del XXI.  Esta primera parte da cuenta  de cómo la escritura de la historia del arte colombiano responde a derroteros de política cultural que hacen parte de la consolidación de modelos desarrollistas y neoliberales aplicados a la nación contemporánea, estos han desencadenado una producción crítica, ensayística y monográfica que da cuenta de las nuevas prácticas artísticas desde múltiples ópticas. Los nuevos imaginarios críticos resultantes están enmarcados en la supuesta modernización del Estado, caracterizada por una vocación descentralizadora, una obsesión febril con el archivo, la profesionalización del espacio del arte y el establecimiento de un espacio de mercado que busca el imposible “equilibrio general”. De esta forma, historias locales con ansias globales, re-inscriben nuestra experiencia de familia Occidental en la línea hegemónica del tiempo, sus mapas y mercados.
Una flor (modernidad) marchita
Authors: Rojas Sotelo Miguel
Published: November 2017

ResumenEsta segunda parte, de la reflexión acerca del tiempo/espacio en la escena artística local moldeada por determinantes históricas de finales de siglo XX y principios del XXI,  discute la insistencia de la clase media intelectual y del mundo del arte en revisitar momentos fundacionales de la nación tales como las expediciones científicas, tendencia que tal vez se explica por la nostalgia o interés de reclamar una modernidad incompleta. Se trata quizás, de un síntoma de esquizofrenia social y, a la vez, de una sensibilidad que en lo retro busca entender el presente que vive la nación. Esta sección hace una lectura comparada del trabajo de las artistas María Elvira Escallón (1954) y Libia Posada (1961) quienes desde una perspectiva múltiple dan cuenta de situaciones del contexto nacional relacionadas con el estado de lo público y su interacción con el mundo doméstico.  Su trabajo revela el deterioro de esa modernidad en el ejercicio de lo patrimonial (duro) y del cuerpo (blando), y que mediante modelos de inclusión y participación en el espacio del arte, posibilita la emergencia de prácticas como las del arte situado (site specific) y en relación, que hacen contrapeso por su énfasis en lo procesual, efímero a lo puramente objetual y de mercado.

Investigar-crear desde la visualidad: los secuædros del viernes santo de Alangasí
Authors: Schlenker Alex
Published: November 2017

ResumenEste artículo sistematiza una serie de reflexiones y gestos estéticos surgidos en el marco del proyecto Turbantes, una aproximación transdisciplinar a la dimensión cultural/estética/política de la fiesta del Viernes Santo de Alangasí (Ecuador) a la que asistí durante consecutivamente entre 2010 y 2015. Se trata de una celebración que desarrolla, desde sus respectivas especificidades (geográficas/de territorio, sociales y culturales), determinadas estrategias de articulación entre lo religioso/espiritual, lo comunitario, la autoridad religiosa/política, entre otras. Como artista visual e investigador, situado simultáneamente en la práctica artística/cinematográfica y la academia, desarrollé una metodología combinada, útil para revisar la relación arte-cultura. Esto desde la idea de unos estudios artísticos como campo crítico que problematice el mismo concepto de cultura desplegado por la Modernidad-colonialidad, proponiendo rutas de investigación desde el quehacer artístico.
Tierra arrasada en la nación del brandin
Authors: Rojas Sotelo Miguel
Published: November 2017

RESUMENEl siguiente artículo se enfoca en la construcción de una imagen de nación mansa, basada en una cultura popular domesticada por las fuerzas desarrollistas del mercado global. El branding de país y su espejo bizarro se hacen presentes en el trabajo de Juan Obando (1980). La escritura y crítica de arte local debe tener la capacidad de dar cuenta de estos contextos y múltiples movimientos en el que los constructos de política cultural, el fetiche de lo expedicionario moderno, lo taxonómico, la era pre-republicana y post-nacional, y el branding acercan la práctica artística a ámbitos de política pública, teoría económica y el diseño social. Los espacios de crítica y escritura de la historia deben establecer unas arqueologías del presente, que en proximidad y cuidadoso estudio hablen de la complejidad de los fenómenos que enfrenta la nación a cumplirse la segunda década del siglo XXI. Palabras ClaveArte; anarquismo; branding; diseño; narcoestética; mercado

Marta Rodríguez, descolonizando la representación documental latinoamericana
Authors: Pablo Gómez Pedro
Published: November 2017

En esta conversación entre la cineasta documental Marta Rodríguez y Pedro Pablo Gómez, antes que hacer un recorrido cronológico por el trabajo la artista, se abordan problemas transversales que están presentes a lo largo de su obra: el cine documental como modo de representación; la construcción de una metodología del cine documental latinoamericano; el carácter decolonial de la obra de Rodríguez y su compromiso indeclinable durante más de cuatro décadas de acompañar las luchas de campesinos, indígenas y afrodescendientes, entre otros. Y es en este abordaje donde Marta Rodríguez, haciendo uso de una memoria extraordinaria, puede tejer un relato en el que se destaca la ética de la artista y su compromiso indeclinable de denuncia de las injusticias sociales, utilizando las tecnologías del cine, no para hablar por las víctimas, sino para hacer escuchar sus voces y mantener vivas sus imágenes; unas imágenes que interpelan el discurso colonial mediante el cual se ha tejido nuestro relato de nación.

Published: November 2017

We consider viscosity solutions of a class of nonlinear degenerate elliptic equations, involving a parameter, on bounded domains.
These arise in the study of eigenvalue problems.
We prove comparison principles and a priori supremum bounds for the solutions.
We also address the eigenvalue problem and, in many instances, show the existence of the first eigenvalue and an associated positive first eigenfunction.
A New Runic Character on the Sedgeford Runic Handle/Ladle: Sound-Value Wanted
Authors: Waxenberger Gaby
Published: November 2017

A new runic inscription was found in 2017. The object could be a handle of a ladle or spoon from Sedgeford, Norfolk. The tentative date of the object ranges from the 8th to the 10th century. The inscription consists of a cross and eight characters, seven of which are clearly runes, but the second character of the sequence is problematic. Although the inscription has no diagnostic rune identifying it as being written in the Old English fuþorc, there is no doubt that the language of the text is Old English. The inscription represents the Old English male personal name B[.]rnferþ. After an overview of the inscription and the runes, and a graph-typological description of character 2, I have attempted to analyze possible phoneme-grapheme relations of Graph 2, assigning the possible readings to certain dialect areas.
Trinity Homily XXIX De Sancto Andrea between Tradition and Innovation
Authors: Cataldi Claudio
Published: November 2017

Recent scholarship has challenged the view of the late twelfth-century Trinity Homilies, and of the contemporary Lambeth Homilies, as two collections that merely continue the earlier Old English vernacular homiletic tradition. This study aims to contribute to the scholarly debate on the Trinity Homilies by considering the elements of tradition and innovation featured in the twenty-ninth sermon of the collection, De Sancto Andrea. Through a discussion on the passage on the ‘Soul’s Address to the Body’ preserved in this homily, I shall show that Trinity XXIX includes both elements of continuity with the ‘Soul and Body’ literature attested in Old English homiletic texts (like the antithetical rhetorical pattern developed in the damned soul’s speech) and new features (like the motif of the ‘Signs of Death’ and the theme of ‘neglectful friends’) which reflect early Middle English developments in the ‘Soul and Body’ theme. I shall argue that the Trinity XXIX homilist probably adapted and reworked a lost Latin source into a poetic passage metrically and thematically consistent with contemporary ‘Soul and Body’ poetry. In the Appendix, I shall discuss the sources for the Latin material embedded in Trinity XXIX.1
Influence of acquisition frame-rate and video compression techniques on pulse-rate variability estimation from vPPG signal
Authors: Cerina Luca , Iozzia Luca , Mainardi Luca
Published: November 2017

In this paper, common time- and frequency-domain variability indexes obtained by pulse rate variability (PRV) series extracted from video-photoplethysmographic signal (vPPG) were compared with heart rate variability (HRV) parameters calculated from synchronized ECG signals. The dual focus of this study was to analyze the effect of different video acquisition frame-rates starting from 60 frames-per-second (fps) down to 7.5 fps and different video compression techniques using both lossless and lossy codecs on PRV parameters estimation. Video recordings were acquired through an off-the-shelf GigE Sony XCG-C30C camera on 60 young, healthy subjects (age 23±4 years) in the supine position. A fully automated, signal extraction method based on the Kanade-Lucas-Tomasi (KLT) algorithm for regions of interest (ROI) detection and tracking, in combination with a zero-phase principal component analysis (ZCA) signal separation technique was employed to convert the video frames sequence to a pulsatile signal. The frame-rate degradation was simulated on video recordings by directly sub-sampling the ROI tracking and signal extraction modules, to correctly mimic videos recorded at a lower speed. The compression of the videos was configured to avoid any frame rejection caused by codec quality leveling, FFV1 codec was used for lossless compression and H.264 with variable quality parameter as lossy codec. The results showed that a reduced frame-rate leads to inaccurate tracking of ROIs, increased time-jitter in the signals dynamics and local peak displacements, which degrades the performances in all the PRV parameters. The root mean square of successive differences (RMSSD) and the proportion of successive differences greater than 50 ms (PNN50) indexes in time-domain and the low frequency (LF) and high frequency (HF) power in frequency domain were the parameters which highly degraded with frame-rate reduction. Such a degradation can be partially mitigated by up-sampling the measured signal at a higher frequency (namely 60 Hz). Concerning the video compression, the results showed that compression techniques are suitable for the storage of vPPG recordings, although lossless or intra-frame compression are to be preferred over inter-frame compression methods. FFV1 performances are very close to the uncompressed (UNC) version with less than 45% disk size. H.264 showed a degradation of the PRV estimation directly correlated with the increase of the compression ratio.
Drug-drug interactions in cancer chemotherapy: an observational study in a tertiary health care centre
Authors: Singh Harminder , Singh Baltej
Published: November 2017

Background:

The objective of this study was to evaluate the occurrence of drug-drug interactions (DDIs) in patients on cancer chemotherapy, with the identification of risk factors for these DDIs.

Methods:

This was a cross-sectional, descriptive study carried out at the Department of Onco-Radiation at Guru Gobind Singh Medical College, Faridkot, Punjab. The DDIs were recorded with the help of a drug interaction/interplay information software.

Results:

In total, 354 interactions were identified from 283 patient records. The mean age of the patients in the study was 49.05±14.35 years. According to the mechanism of interaction, 306 (86.44%) drug interactions were classified as pharmacokinetic and 48 (13.56%) as pharmacodynamic in nature.

Conclusions:

Sensitization of the treating oncologist and the establishment of alerts, such as electronic alerts or a novel fully digital computerized technology that gives a warning when a health expert enters a patient’s prescription orders into the electronic medical documentation, can be helpful in controlling DDIs.
Identifying error types in visual diagnostic skill assessment
Authors: Ravesloot Cécile J. , van der Gijp Anouk , van der Schaaf Marieke F. , Huige Josephine C.B.M. , ten Cate Olle , Vincken Koen L. , Mol Christian P. , van Schaik Jan P.J.
Published: November 2017

Background:

Misinterpretation of medical images is an important source of diagnostic error. Errors can occur in different phases of the diagnostic process. Insight in the error types made by learners is crucial for training and giving effective feedback. Most diagnostic skill tests however penalize diagnostic mistakes without an eye for the diagnostic process and the type of error. A radiology test with stepwise reasoning questions was used to distinguish error types in the visual diagnostic process. We evaluated the additional value of a stepwise question-format, in comparison with only diagnostic questions in radiology tests.

Methods:

Medical students in a radiology elective (n=109) took a radiology test including 11–13 cases in stepwise question-format: marking an abnormality, describing the abnormality and giving a diagnosis. Errors were coded by two independent researchers as perception, analysis, diagnosis, or undefined. Erroneous cases were further evaluated for the presence of latent errors or partial knowledge. Inter-rater reliabilities and percentages of cases with latent errors and partial knowledge were calculated.

Results:

The stepwise question-format procedure applied to 1351 cases completed by 109 medical students revealed 828 errors. Mean inter-rater reliability of error type coding was Cohen’s κ=0.79. Six hundred and fifty errors (79%) could be coded as perception, analysis or diagnosis errors. The stepwise question-format revealed latent errors in 9% and partial knowledge in 18% of cases.

Conclusions:

A stepwise question-format can reliably distinguish error types in the visual diagnostic process, and reveals latent errors and partial knowledge.

Multi-objective optimization of a functionally graded sandwich panel under mechanical loading in the presence of stress constraint
Authors: Ashjari Mohammad , Khoshravan Mohammad Reza
Published: November 2017

A method was presented for multi-objective optimization of material distribution of simply supported functionally graded (FG) sandwich panel, and sensitivity analyses of optimal designs were also conducted based on design variables and objective functions. The material composition was assumed to vary only in the thickness direction. Piecewise cubic interpolation of volume fractions was used to calculate volume fractions of constituent material phases at a point; these fractions were defined at a limited number of evenly spaced control points. The effective material properties of the panel were obtained by applying the linear rule of mixtures. The behavior of FG sandwich panel was predicted by Reddy’s assumptions of third-order shear deformation theory. Exact solutions for deflections and stresses of simply supported sandwich panel were presented using the Navier-type solution technique. The volume fractions at control points, material, and thickness of the faces which were selected as decision variables were optimized by a multi-objective evolutionary algorithm known as the fast and elitist multi-objective genetic algorithm (NSGA-II). The mass and deflection of the model were considered the objective functions to be minimized with stress constraints. This model was optimized to verify the capability and efficiency of the proposed model under mechanical loading. The framework proposed for designing FG sandwich panel under pure mechanical conditions was furnished by the results.
The typology of property words in Oceanic languages
Authors: van Lier Eva
Published: November 2017

This paper describes the morphosyntactic behavior of different semantic types of property words in a balanced sample of 36 Oceanic languages. After a brief general introduction to the functional typology of property words, I first discuss diversity in Oceanic property word classes from a family-internal perspective. In the second part of the paper, Oceanic property words are placed in a world-wide typological perspective. Specifically, I test their behavior with regard to two implicational universals proposed in the literature, concerning the relation between the encoding of predicative property words, the presence of grammatical tense, and locus of marking at the clause level. In typological studies, the Oceanic language family has been claimed to display verbal predicative property words, to lack tense, and to be head- or zero-marking, with marginal exceptions. This paper shows that, even though such an overall profile can be discerned, Oceanic property words exhibit more variation than is acknowledged in crosslinguistic research. Moreover, my findings for property word classes are fitted into a larger picture of lexical categorization in Oceanic languages.
Why is children’s interpretation of doubly quantified sentences non-isomorphic?
Authors: Kiss Katalin É. , Zétényi Tamás
Published: November 2017

The initial hypothesis examined in this paper is that Hungarian preschoolers assign to sentences containing two numerical quantifiers and a distributivity marker the same isomorphic distributive interpretation as Hungarian adults do. This hypothesis is partially refuted by Experiment 1, a truth value judgement task, and Experiment 2, a forced choice task, which show that children can access distributive readings, however, they tend to accept both isomorphic and inverse scope. Experiment 3, an act-out task, demonstrates that if there are no strong pragmatic cues to enforce a distributive interpretation, children’s primary interpretation is the collective reading. This leads us to the formulation of a new hypothesis: if the default reading of a doubly quantified sentence for preschoolers is the collective interpretation, in line with scope economy, then a distributive reading always represents the revision of the collective interpretation. This is confirmed by Experiment 4, showing that inverse answers have an increased reaction time. The new hypothesis can explain the lack of isomorphism in children’s interpretation of distributive scope as follows: since the distributive reading is dissociated from the linear flow of speech, the linear order of the two quantifiers does not necessarily determine scope order; children can base relative scope on the hierarchy of grammatical functions, on pragmatic cues, etc.

Lead acetate toxicity on human lymphocytes at non-cytotoxic concentrations detected in human blood
Authors: Zarei Mohammad Hadi , Pourahmad Jalal , Aghvami Marjan , Soodi Maliheh , Nassireslami Ehsan
Published: November 2017

Lead (Pb) is one of the most important heavy metals that possess many applications in different kinds of industrial procedures and consumer products. The adverse effects of Pb on different parts of the immune system have been reported in various studies. Although it has been shown that high concentrations of Pb have low cytotoxicity on human lymphocytes, the effects of non-cytotoxic concentrations of Pb (detected in human blood) on cellular organelles and oxidative stress factors of human lymphocytes have yet to be determined. In this study, human lymphocytes were obtained from the blood of healthy male volunteers through the use of the Ficoll standard method. The intention of this paper was to determine the effects of non-cytotoxic concentrations of Pb on human lymphocytes using the accelerated cytotoxicity mechanism screening technique. For determination of cell viability, lymphocytes were treated with 0–1 m
Comparison of some organic and inorganic ion exchangers concerning the sorption of Ce(III), Te(IV), Zr(IV), Hf(IV) and Nb(V)

The sorption behaviors of Ce(III), as a representative of trivalent lanthanide ions, and Te(IV), Zr(IV) and Nb(V) as fission products representatives, as well as Hf(IV), from various aqueous media on some synthesized inorganic exchangers, as well as commercially available organic ion exchangers were studied and compared. Organic cation exchanger Dowex-50WX8 and organic anion exchangers AG-1X8 and AG-2X8 were utilized. Synthesized inorganic ion exchangers were zirconium titanium phosphate (ZrTiP) of different Zr:Ti mole ratios and ceric tungstate (CeW). The sorption was carried out from mineral acid solutions as well as EDTA and DTPA solutions. The radioactive isotopes, 95Zr, 95Nb, 123mTe, 141Ce and 181Hf were used to trace the sorption behaviors of the corresponding elements, which were studied in mixtures of them. The differences between the sorption behaviors of the studied metal ionic species on both kinds of ion exchangers were interpreted and discussed in this work.
Game Responses During Young Padel Match Play: Age and Sex Comparisons

García-Benítez, S, Courel-Ibáñez, J, Pérez-Bilbao, T, and Felipe, JL. Game responses during young padel match play: age and sex comparisons. J Strength Cond Res 32(4): 1144–1149, 2018—The purpose of this study was to assess match activity profile and temporal structure in U-16 and U-18 male and female padel players from the 2014 Spanish Youth National Championship. A total of 1,670 rallies from 12 matches were recorded through systematic observation. Variables pertaining to game and point duration, rest interval time, number of strokes per rally (SR), and match total duration were registered. Current findings show that significant influences of age and sex on game demands in youth padel players strengthen the importance of knowing specific game characteristics during formative stages for training accordingly. In particular, padel match activity in youth players was characterized by longer rallies, longer resting interval time, and more number of SR compared with other racket sports, resulting in lower effort index. More specifically, results revealed an increment on match requirements in U-18 players compared with U-16. Besides, we found a greater use of lobs in females, particularly in U-16 players. This information may constitute a useful guide for the design of appropriate game strategies and specific-training sessions according to competitive demands in youth padel players.

J Strength Cond Res 32(11): 3232–3238, 2018—This study assessed the interday reliability of a testing battery for the assessment of physical qualities of rugby league players. Fifty players (age 17.1 ± 1.1 years; stature 181.3 ± 6.3 cm; and body mass 89.0 ± 11.6 kg) from 3 Super League academies participated in this study. Tests of countermovement jump performance, 10- and 20-m sprint performance, change of direction, medicine ball throw, and a modified Yo-Yo Intermittent Recovery Test Level 1 (prone Yo-Yo IR1) were completed on 3 separate occasions. Between-day intraclass correlation coefficient, typical error (TE), coefficient of variation, and the smallest worthwhile change (SWC) were calculated to determine the reliability and sensitivity of each measure. Individual tests (except medicine ball throw) were not systematically different between trials (p > 0.05), with an interday variability that was <10%. In all instances, the TE was larger than the calculated SWC change, although variability was less than that typically observed after a training intervention or specific training period (i.e. preseason). Using a magnitude-based inference approach, we present the required change for all performance tests to be 75% confident and the change is beneficial. This simple and time efficient testing battery is sufficiently reliable to detect previously observed changes in a range of physical qualities of rugby league players.

Dowse, RA, McGuigan, MR, and Harrison, C. Effects of a resistance training intervention on strength, power, and performance in adolescent dancers. J Strength Cond Res 34(12): 3446–3453, 2020—The aim of this study was to determine whether a 9-week resistance training program could have a significant effect on maximum lower-body strength and power, dynamic balance, and dance performance in adolescent dancers. Twelve competitive adolescent female dancers trained in jazz, ballet, and contemporary were recruited from local dance schools and assigned to a resistance training group (dance experience 9.2 ± 2.4 years; age 14.2 ± 1.9 years; height 155.6 ± 9.1 cm; and mass 48.9 ± 13.8 kg). Anthropometry (height, seated height, mass, and skinfolds), subjective dancing performance, dynamic balance (eyes open [EO] and eyes closed), maximum lower-body strength (isometric midthigh pull), and power (vertical countermovement jump, squat jump, and single-leg countermovement jump) were assessed before and after the 9-week intervention period. Post-testing identified a significant improvement EO overall stability (p = 0.003; effect size [ES] = 0.88), EO anterior-posterior stability (p = 0.003; ES = 0.92), peak force (p < 0.001; ES = 0.61), peak power (p = 0.021; ES = 0.22), and subjective dancing performance (p = 0.008; ES = 0.76). These results were accompanied by a trivial but significant change in mass (p = 0.023; ES = 0.09) that was attributed to growth and no significant change in body fat or the sum of skinfolds. This study demonstrated that resistance training can have a significant effect on dynamic balance, maximum lower-body strength, and power without adversely affecting artistic or aesthetic components. The results suggest that incorporating resistance training may enhance strength and power adaptations and manage growth-related changes in adolescent dancers.

Beaudoin, CM, Cox, Z, Dundore, T, Thomas, T, Kim, J, and Pillivant, D. Effect of bench press load knowledge on repetitions, rating of perceived exertion, and attentional focus. J Strength Cond Res 32(2): 514–519, 2018—Few studies have examined the role of the teleoanticipation during resistance training. The purpose of this study was to examine the effect of bench press (BP) load knowledge on repetitions completed, ratings of perceived exertion (RPEs), and attentional focus (% associative). Thirty-six recreationally active resistance-trained men (n = 25) and women (n = 11) participated in this study (age = 20.97 ± 1.87 years; ht = 174.12 ± 9.41 cm; and mass = 80.14 ± 14.03 kg). All subjects completed 3 testing sessions: (a) 1 repetition maximum (1RM) BP determination; (b) submaximal BP repetitions to fatigue known load (KL); and (c) submaximal BP repetitions to fatigue unknown load (UL). Known load and UL sessions were randomized and counterbalanced and both completed at 70% 1RM. An estimated weight ratio was computed using the subject's estimate of the UL weight relative to the KL weight. An independent samples t-test revealed no significant testing order difference for the estimated weight ratio. Two-way repeated-measures analysis of variances revealed no significant differences in the number of repetitions (p = 0.63), RPE (p = 0.18), or attentional focus (% associative) (p = 0.93) between the KL and UL conditions. Pearson correlations found a moderate positive association between KL repetitions completed and % associative focus when the UL was completed before the KL. Load knowledge did not influence the number of repetitions, RPE, or attentional focus while completing the BP. Further research examining the use of pacing strategies, RPE, and attentional focus during KL and UL conditions are warranted.

Reelin controls neuronal migration and layer formation. Previous studies inreelermice deficient in Reelin focused on the result of the developmental process in fixed tissue sections. It has remained unclear whether Reelin affects the migratory process, migration directionality, or migrating neurons guided by the radial glial scaffold. Moreover, Reelin has been regarded as an attractive signal because newly generated neurons migrate toward the Reelin-containing marginal zone. Conversely, Reelin might be a stop signal because migrating neurons inreeler, but not in wild-type mice, invade the marginal zone. Here, we monitored the migration of newly generatedproopiomelanocortin-EGFP-expressing dentate granule cells in slice cultures fromreeler,reeler-like mutants and wild-type mice of either sex using real-time microscopy. We discovered that not the actual migratory process and migratory speed, but migration directionality of the granule cells is controlled by Reelin. While wild-type granule cells migrated toward the marginal zone of the dentate gyrus, neurons in cultures fromreelerandreeler-like mutants migrated randomly in all directions as revealed by vector analyses of migratory trajectories. Moreover, live imaging of granule cells inreelerslices cocultured to wild-type dentate gyrus showed that thereelerneurons changed their directions and migrated toward the Reelin-containing marginal zone of the wild-type culture, thus forming a compact granule cell layer. In contrast, directed migration was not observed when Reelin was ubiquitously present in the medium ofreelerslices. These results indicate that topographically administered Reelin controls the formation of a granule cell layer.

SIGNIFICANCE STATEMENTNeuronal migration and the various factors controlling its onset, speed, directionality, and arrest are poorly understood. Slice cultures offer a unique model to study the migration of individual neurons in an almost natural environment. In the present study, we took advantage of the expression ofproopiomelanocortin-EGFPby newly generated, migrating granule cells to analyze their migratory trajectories in hippocampal slice cultures from wild-type mice and mutants deficient in Reelin signaling. We show that the compartmentalized presence of Reelin is essential for the directionality, but not the actual migratory process or speed, of migrating granule cells leading to their characteristic lamination in the dentate gyrus.
To Revive Delight: A Poet's Restaurant Reviews in Early 1990s Prague
Authors: Weil Abigail
Published: November 2017

In 1993, the Prague-based newspaper Lidové noviny (The People's News) ran a short-lived restaurant review column, Básník má hlad (The Poet Is Hungry). The author was Petr Král, a poet and essayist who had recently returned to Prague after two decades of exile in Paris. In this article, I contextualize Král's restaurant reviews within his oeuvre and in the history of Czech restaurant culture. The first half describes the evolution of restaurants in Czech culture and literature from the First Czechoslovak Republic through the communist period. The second half is devoted to close readings of Král's restaurant reviews. I find that they are consistent with the restorative nature of the Czech political and economic transition after communism. To Král, the restaurant represents a microcosm of society. Thus, in the spirit of restoration and revitalization, he elevates the genre of restaurant reviews, infusing them with political urgency and a sense of poetry.
Marketing Soviet Nostalgia: The Many Faces of Buratino
Authors: Goering Laura
Published: November 2017

Nostalgia for the foods consumed in childhood is a phenomenon extensively documented by food studies scholars and exploited by marketers around the world. This article traces the evolution of the Soviet children's soft drink Buratino from its origins in the Brezhnev era through a variety of post-Soviet incarnations. The character featured on the label, drawn from A. N. Tolstoy's 1935 book based on Carlo Collodi's Adventures of Pinocchio, is both instantly recognizable and remarkably protean in nature, combining the archetype of the trickster from the original literary text with a more benign representative of Soviet values depicted in a 1975 film adaptation. Using Douglas Holt's premises in his book How Brands Become Icons (2004), I argue that what would seem like an easy transition from literary character to advertising icon is complicated by the limitations of nostalgia-based marketing, changing consumer perceptions, and lack of clarity in trademark law. The article concludes with an analysis of the marketing strategy of the Kazakh company Caspian Beverage Holding, which has been singularly successful in recognizing the potential power of the brand and adapting it to a new, post-Soviet market.
