Published: August 2019

Let V be a finite set of positive integers with sum equal to a multiple of the integer b . When does V have a partition into b parts so that all parts have equal sums? We develop algorithmic constructions which yield positive, albeit incomplete, answers for the following classes of set V , where n is a given positive integer: (1) an initial interval { a ∈ ℤ + : a ≤ n } ; (2) an initial interval of primes { p ∈ ℙ : p ≤ n } , where ℙ is the set of primes; (3) a divisor set { d ∈ ℤ + : d | n } ; (4) an aliquot set { d ∈ ℤ + : d | n , d < n } . Open general questions and conjectures are included for each of these classes.

Prevalencia y persistencia del insomnio crónico
Authors: Díaz Cabezas Ricardo , Ruano Mario Ivan 
Published: August 2019

Introducción: el insomnio, especialmente cuando se cronifica, se convierte en una patología con marcadas implicaciones en la salud física y mental. No obstante su importancia, en nuestro país existen pocos estudios poblacionales sobre su comportamiento epidemiológico. Estudios previos realizados en el departamento de Caldas mostraron una elevada prevalencia de insomnio global con cifras alrededor de 47%.
Objetivo: establecer la frecuencia, características sociodemográficas y persistencia a dos años del insomnio crónico, en una muestra poblacional representativa de la ciudad de Manizales. Sujetos y métodos: estudio transversal mediante entrevista domiciliaria en diferentes estratos socioeconómicos en mayores de 18 años, con queja de insomnio en el estudio previo de trastornos de sueño en Caldas (2008), que incluyó 530 personas de las cuales 228 tenían insomnio (agudo o crónico), lo cual arrojó una prevalencia global de 43.9%. Para el análisis de la información se empleó el paquete estadístico Epiinfo 6.04d/.
Resultados: el seguimiento a dos años se pudo realizar a 218 personas, y de éstas el insomnio continuaba en 175, lo cual indicó una prevalencia de insomnio crónico de 33% y una persistencia del mismo de 80.2%. Cuando sólo se estimó el insomnio con repercusión diurna la prevalencia fue de 10.9%. En más de la mitad de los individuos el insomnio había estado presente entre cinco y diez años. El aumento en edad fue el único factor asociado para una mayor frecuencia. A pesar de la persistencia y severidad del insomnio, sólo 18.3% lo habían informado al médico.
Conclusiones: las prevalencias halladas de insomnio global, crónico y con repercusión diurna se encuentran entre los rangos mencionados en la literatura y se detectó una elevada persistencia y duración del insomnio crónico. Lo anterior, y dadas sus consecuencias negativas sobre individuos y comunidades, amerita una búsqueda activa de esta condición en la práctica clínica y medidas gubernamentales apropiadas para su prevención y manejo
Rabdomiolisis por levetiracetam
Authors: Sierra Umaña Sebastián Felipe , Olarte Jessica Tatiana , Cáceres Dolli Yineth 
Published: August 2019

Introducción: el levetiracetam (LEV) es un medicamento anticonvulsivo con mecanismo de acción desconocido. La mayoría de efectos adversos son de intensidad leve a moderada, siendo la rabdomiolisis (RBM) uno recientemente descrito, con pocos casos reportados en el mundo.
Descripción del caso: hombre de 35 años, con antecedentes de obesidad y epilepsia generalizada sin tratamiento, quien cursa con estatus epiléptico, controlado con benzodiacepina y LEV satisfactoriamente. Examen neurológico y tomografía de cráneo simple descartan alteraciones asociadas. Presenta lesión renal aguda por RBM que a pesar de estatus epiléptico controlado y manejo con soporte dialítico, progresan hacia el deterioro. Se sospecha RBM por LEV luego de descartarse etiología autoinmune y RBM por inmovilización de paciente obeso. Se suspende el LEV observándose descenso rápido de la creatina quinasa (CQ) y mejoría progresiva de la lesión renal aguda, confirmándose así la sospecha diagnóstica. Se logra destete y retiro de soporte dialítico, dándose alta hospitalaria con función renal y CQ normales, ácido valproico como anticonvulsivante y alerta de contraindicación para manejo con LEV.
Discusión: el LEV es un antiepiléptico cuyos efectos adversos más frecuentes son: somnolencia, mareo, irritabilidad, cefalea y fatiga. La RBM por LEV es un efecto adverso infrecuente (pocos casos reportados en el mundo y ninguno reportado en Colombia). La sociedad europea incluyó dentro de los rótulos del LEV este efecto adverso recientemente. Su tratamiento se basa en suspender el medicamento y administrar terapia de soporte, así como, seguimiento clínico estrecho.
Conclusión: la RBM por LEV es un efecto adverso poco frecuente que debe sospecharse en presencia de lesión renal aguda por RBM sin otras causas explicables

Published: August 2019

Introducción: la carga sintomática de pacientes con neoplasias mieloproliferativas crónicas Filadelfia negativas (NMC-PhN) afecta la calidad de vida (CV). Existen escalas para evaluar la magnitud de los síntomas, una de ellas, MPN-SAF-10. En nuestra región existe escasa información sobre CV de pacientes con NMC-PhN.
Objetivos: estimar el puntaje de calidad de vida con la escala MPN-SAF-10 en pacientes con NMC-PhN atendidos en el Hospital de San José (Bogotá, Colombia) y explorar asociaciones entre el tiempo de tratamiento, carga de complicaciones y el efecto en la CV.
Material y métodos: estudio de corte transversal analítico para evaluar CV basada en carga sintomática de pacientes con NMC-PhN del Hospital de San José (Bogotá, Colombia). Se realizó análisis descriptivo y estratificado de calidad de vida, tratamiento citorreductor y de diferentes complicaciones, así como pruebas de asociación de los puntajes de riesgo de cada enfermedad con sus respectivos puntajes de CV.
Resultados: en 64 pacientes la escala MPN-SAF-10 documentó medianas de puntajes globales de CV de 3 (RIC 1-6), MPN-SAF-10 de 20 (RIC 8-32). Un 49% de los pacientes tuvo algún grado de alteración (30% moderada y 19% severa), sin diferencias entre las tres enfermedades. Los puntajes de CV no variaron entre las NMC-PhN. El tratamiento y duración del mismo no se correlacionaron con la escala de MPN-SAF-10 (hidroxiúrea r: - 0.27; ruxolitinib r: 0.12).
Conclusiones: en pacientes con NMC-PhN, la evaluación de CV con la escala MPN-SAF-10 evidencia algún grado de afectación a pesar del tratamiento; ésta es útil para objetivar dicha afectacióny debe implementarse en la práctica clínica
LL Com: A Near-contact Total Eclipsing Binary at a Key Stage of Evolution
Authors: Hu Ke , Chen Kun , Xiang Fu-Yuan , Yu Yun-Xia , Zhao Er-Gang 
Published: August 2019

Abstract
Despite the discovery of LL Com, a Lyrae-type eclipsing binary system, approximately 60 yr ago, little has been found concerning its detailed photometry and orbital-period change until now. In this paper, we present the first multi-band charge-coupled-device photometric light curves, from which a significant luminosity reduction around the primary eclipse is revealed. Based on LAMOST data, we first determined LL Com’s spectrum as F1V and then analyzed the light curves with the 2015 version of the Wilson-Devinney code. The fact that LL Com is a near-contact binary system with a semi-detached configuration, where the secondary component only fills its Roche lobe and the primary component fills more than 95% of its Roche lobe, is suggested through the photometric solution. In addition, according to archival photometry and previously published times of minima, a secular period increase at a rate of

was found, which implies a continuous mass transfer from the secondary to the primary. Utilizing the photometric solution and the simulations of single-particle trajectories, we propose the existence of a cool spot on the surface of the primary component. This cool spot can be naturally produced by the impacts that occur during mass flow, and it also successfully interprets the luminosity reduction in the light curves. Finally, with the combination of thermal relaxation oscillation theory and the Roche-Lobe model, we conclude that LL Com is transitioning from the semi-detached to the detached phase.
The Masses of Supernova Remnant Progenitors in M83

Abstract
We determine the ages of the young, resolved stellar populations at the locations of 237 optically identified supernova remnants in M83. These age distributions put constraints on the progenitor masses of the supernovae that produced 199 of the remnants. The other 38 show no evidence for having a young progenitor and are therefore good Type Ia SNR candidates. Starting from Hubble Space Telescope broadband imaging, we measured resolved stellar photometry of seven archival WFC3/UVIS fields in F336W, F438W, and F814W. We generate color–magnitude diagrams of the stars within 50 pc of each SNR and fit them with stellar evolution models to obtain the population ages. From these ages we infer the progenitor mass that corresponds to the lifetime of the most prominent age within the past 50 Myr. In this sample, there are 47 SNRs with best-fit progenitor masses >15 M
⊙, and 5 of these are >15 M
⊙ at 84% confidence. This is the largest collection of high-mass progenitors to date, including our highest-mass progenitor inference found so far, with a constraint of <8 Myr. Overall, the distribution of progenitor masses has a power-law index of

, steeper than Salpeter initial mass function (−2.35). It remains unclear whether the reason for the low number of high-mass progenitors is due to the difficulty of finding and measuring such objects or because only a fraction of very massive stars produce supernovae.
A Connection between Spectral Width and Energetics As Well As Peak Luminosity in Fermi Gamma-Ray Bursts
Authors: Peng Z. Y. , Zhao X. H. , Yin Y , Wang D. Z. 
Published: August 2019

Abstract
We have revisited the spectral width in the EF

E
spectrum of gamma-ray bursts with the BEST peak flux P and time-integrated F spectral data provided by the Fermi GBM Burst Catalog. We first compute the BEST spectral widths to compare with some typical physics models. Our analysis results consist with the previous results: blackbody emission alone cannot explain the observed spectrum and most of the observed spectra cannot be interpreted by the synchrotron radiation. We then check the correlations between the spectral width and the observable model-independent burst properties of duration, fluence, and peak flux and find that positive correlations exist between them for both the P and F spectra. Moreover, the short burst appears to extend the correlation found for the long burst. We further demonstrate that these positive correlations also exist in the cosmological rest frame; that is, the spectral width correlates with the isotropic-equivalent energy E
iso as well as the isotropic-equivalent peak luminosity L
iso for different energy bands and timescales. Our results show that the wider bursts have larger energy and luminosity. Moreover, short bursts would appear to extend this trend qualitatively. Taking the Amati relation into account, we tend to believe that the spectral shape is related to energy and luminosity.
On Exact Laws in Incompressible Hall Magnetohydrodynamic Turbulence
Authors: Ferrand R. , Galtier S. , Sahraoui F. , Meyrand R. , Andrés N. , Banerjee S. 
Published: August 2019

Abstract
A comparison is made between several existing exact laws in incompressible Hall magnetohydrodynamic turbulence in order to show their equivalence, despite stemming from different mathematical derivations. Using statistical homogeneity, we revisit the law proposed by Hellinger et al. and show that it can be written, after being corrected by a multiplicative factor, in a more compact form implying only flux terms expressed as increments of the turbulent fields. The Hall contribution of this law is tested and compared to other exact laws derived by Galtier and Banerjee & Galtier using direct numerical simulations of three-dimensional electron MHD turbulence with a moderate mean magnetic field. We show that the studied laws are equivalent in the inertial range, thereby offering several choices on the formulation to use depending on the needs. The expressions that depend explicitly on a mean (guide) field may lead to residual errors in estimating the energy cascade rate; however, we demonstrate that this guide field can be removed from these laws after mathematical manipulation. Therefore, it is recommended to use an expression independent of the mean guide field to analyze numerical or in situ spacecraft data.
A Chandra Study: Are Dwarf Carbon Stars Spun Up and Rejuvenated by Mass Transfer?

Abstract
Carbon stars (with C/O > 1) were long assumed to all be giants, because only asymptotic giant branch (AGB) stars dredge up significant carbon into their atmospheres. The case is nearly ironclad now that the formerly mysterious dwarf carbon (dC) stars are actually far more common than C giants and have accreted carbon-rich material from a former AGB companion, yielding a white dwarf (WD) and a dC star that has gained both significant mass and angular momentum. Some such dC systems have undergone a planetary nebula phase, and some may evolve to become CH, CEMP, or Ba giants. Recent studies indicate that most dCs are likely from older, metal-poor kinematic populations. Given the well-known anticorrelation of age and activity, dCs would not be expected to show significant X-ray emission related to coronal activity. However, accretion spin-up might be expected to rejuvenate magnetic dynamos in these post-mass-transfer binary systems. We describe our Chandra pilot study of six dCs selected from the SDSS for Hα emission and/or a hot WD companion, to test whether their X-ray emission strength and spectral properties are consistent with a rejuvenated dynamo. We detect all six dCs in the sample, which have X-ray luminosities ranging from log

–29.7, preliminary evidence that dCs may be active at a level consistent with stars that have short rotation periods of several days or less. More definitive results require a sample of typical dCs with deeper X-ray observations to better constrain their plasma temperatures.
The Gemini/HST Galaxy Cluster Project: Environment Effects on the Stellar Populations in the Lynx Clusters at z = 1.27

Published: August 2019

Abstract
Few detailed investigations of stellar populations in passive galaxies beyond z ≈ 1 are based on deep spectroscopic observations, due to the difficulty in obtaining such data. We present a study of stellar populations, structure, and mass-to-light ratios (M/L) of a large sample of bulge-dominated galaxies in the two z = 1.27 clusters Lynx E and Lynx W, based on deep ground-based optical spectroscopy combined with imaging from the Hubble Space Telescope. We find that Lynx E has a well-defined core of red passive galaxies, while Lynx W lacks such a core. If all the sample galaxies evolve similarly in size from z = 1.27 to the present, the data would allow only 0.1 dex size growth at a fixed dynamical mass. However, to link the Lynx central galaxies to brightest cluster galaxies similar to those of low-redshift clusters, the Lynx galaxies would have to grow by at least a factor 5, possibly through major merging. The M/L ratios and the Balmer absorption lines of the Lynx galaxies are consistent with passive evolution of the stellar populations from z = 1.27 to the present and support ages of 1–3 Gyr. The galaxies in the outskirts of the clusters contain younger stellar populations than found in the cluster cores. However, when evolved passively to z ≈ 0 both populations are consistent with the observed populations in the Coma cluster galaxies. The bulge-dominated emission line galaxies in the clusters are dominated by stellar populations with subsolar metallicities. Thus, additional enrichment of these is required to produce Coma-like stellar populations by z ≈ 0.
