Published: July 2022

En este trabajo se analiza el comportamiento de las perturbaciones de energía primaria del viento en los sistemas de generación eólica conectados a la red, mediante la simulación del control orientado de voltaje (COV) de un aerogenerador tipo 4 de 2 MW utilizando Matlab/Simulink. En el COV las corrientes y voltajes son controladas transformando los ejes estacionarios abc de la red, en un cuadro síncrono giratorio de ejes dq0 utilizando la transformada de Park, de esta manera se utiliza un control de lazo bloqueado de fase (PLL) para la sincronización de fases de la red con el convertidor de fuente de voltaje (VSC) ajustando el índice de modulación y el ángulo de fase, un control de voltaje (lazo externo) donde se toman las señales de voltaje de la barra de corriente directa Vcd que sirve de referencia a las señales de salida de corriente en el eje d y una sintonización de 0 en el eje q para la limitación de entrega de potencia reactiva a la red, un control de corriente (lazo interno) que toma las señales de referencia Idq y juntamente con las señales de corriente de la salida del inversor, se realiza el control de potencias activa y reactiva mediante una retroalimentación desacoplada. Como resultado se obtienen las señales Vdq de referencia para la conmutación de los IGBT´s por medio de la modulación por ancho de pulso de espacio vectorial (SVPWM) entregando a la salida del inversor la máxima cantidad de potencia activa entregado por el aerogenerador, manteniendo las variables de estado como voltaje y frecuencia para la conexión a la red, mediante un control orientado de voltaje estable a fluctuaciones de entradas del viento.

La evaluación del rendimiento de una bomba de calor de expansión directa asistida por energía solar (DX-SAHP, por sus siglas en inglés) fue analizada mediante simulación numérica del proceso de estrangulamiento en el dispositivo de expansión. Los valores experimentales de operación del sistema fueron validados mediante prueba de normalidad con 95 % de confianza. Una válvula de expansión E2V09SSF fue modelada para el análisis numérico en el módulo Fluent del software ANSYS. El mejor mallado de la válvula generó 263524 elementos y 50449 nodos con una métrica excelente, de 0.2334 de skewness. La temperatura y presión del refrigerante fueron definidas como condiciones de contorno en la entrada del dispositivo de expansión, además de la velocidad. Se utilizaron las ecuaciones de continuidad, momento y energía, considerando un modelo k-epsilon RNG. La presión del refrigerante al salir del dispositivo de expansión obtenidos mediante simulación se comparó con valores experimentales determinados en el prototipo de un sistema DX-SAHP. La presión del refrigerante obtenida mediante simulación para un tiempo de calentamiento de 0 a 40 minutos fue de 161.61, 186.50 y 238.33 kPa. El error absoluto entre la presión experimental y simulada fue de 4.07 kPa, mientras que el error relativo fue inferior a 2 %.
Some Remarks on Even-Hole-Free Graphs
Authors: Song Zi-Xia 
Published: July 2022

A vertex of a graph is bisimplicial if the set of its neighbors is the union of two cliques; a graph is quasi-line if every vertex is bisimplicial. A recent result of Chudnovsky and Seymour asserts that every non-empty even-hole-free graph has a bisimplicial vertex. Both Hadwiger's conjecture and the Erdős-Lovász Tihany conjecture have been shown to be true for quasi-line graphs, but are open for even-hole-free graphs. In this note, we prove that every even-hole-free graph $G$ with $\omega(G)<\chi(G)=s+t-1$ satisfies the Erdős-Lovász Tihany conjecture provided that $ t\geq s > \chi(G)/3$; every $9$-chromatic graph $G$ with $\omega(G)\leq 8$ has a $K_4\cup K_6$ minor; for all $k\geq 7$, every even-hole-free graph with no $K_k$ minor is $(2k-5)$-colorable. Our proofs rely heavily on the structural result of Chudnovsky and Seymour on even-hole-free graphs.

Published: July 2022

Dyslalia is an articulation disorder that is not caused by abnormalities in the central nervous system or the anatomy of speech organs. This study aims to determine the success rate of therapy with integral stimulation methods for a 3-year-7-month-old female patient. This research activity was carried out for 2 months in the Bayu Asih District Hospital Purwakarta. The chosen research method is a case study. Initial assessment of the case was carried out by interviewing, observing, testing, and studying documents, and then conducting therapy for 15 meetings which were observed and evaluated. The application of the method of integral stimulation to therapy is carried out with the aim of reducing the omission of the consonant /m/ at the word level. In this study, the success rate of therapy was 41.6%. Patients experienced a reduction in the number of omissions in the targeted consonant by 5 points, at the time of the pretest the patient experienced omission in 8 of the 12 test items, and in the posttest omission reduced to 3 test items. Based on the scale designed in this study, the application of the method of integral stimulation was considered quite successful
Different Ice-shell Geometries on Europa and Enceladus due to Their Different Sizes: Impacts of Ocean Heat Transport
Authors: Kang Wanying 
Published: July 2022

Abstract
On icy worlds, the ice shell and subsurface ocean form a coupled system—heat and salinity flux from the ice shell induced by the ice-thickness gradient drives circulation in the ocean, and in turn, the heat transport by ocean circulation shapes the ice shell. Therefore, understanding the dependence of the efficiency of ocean heat transport (OHT) on orbital parameters may allow us to predict the ice-shell geometry before direct observation is possible, providing useful information for mission design. Inspired by previous works on baroclinic eddies, I first derive scaling laws for the OHT on icy moons, driven by ice topography, and then verify them against high-resolution 3D numerical simulations. Using the scaling laws, I am then able to make predictions for the equilibrium ice-thickness variation knowing that the ice shell should be close to heat balance. The ice shell on small icy moons (e.g., Enceladus) may develop strong thickness variations between the equator and pole driven by the polar-amplified tidal dissipation in the ice; in contrast, the ice shell on large icy moons (e.g., Europa, Ganymede, Callisto, etc.) tends to be flat due to the smoothing effects of the efficient OHT. These predictions are manifested by the different ice-evolution pathways simulated for Enceladus and Europa, considering the ice freezing/melting induced by ice dissipation, conductive heat loss, and OHT as well as the mass redistribution by ice flow.
Implications of an Extended Dark Energy Model with Massive Neutrinos

Abstract
Recently there have been reports of finding a lower bound on the neutrino mass parameter (Σm

ν
) when using the Atacama Cosmology Telescope (ACT) and SPTpol data; however, these bounds on the Σm

ν
are still weaker for most cases around the 1σ level. In this context, here in this work, we study the consequences of using an enlarged four parameter dynamical dark energy equation of state on the neutrino mass parameter as well as on the Hubble and S8 tensions. The four parameter dark energy equation of state incorporates a generic nonlinear monotonic evolution of the dark energy equation of state, where the four parameters are the early and the present value of the equation of state, the transition scale factor, and the sharpness of the transition. We report that with lensing-marginalized Planck + BAO + Pantheon and prior on absolute magnitude M

Simultaneous Dependence of Matter Clustering on Scale and Environment
Authors: Wang Yun , He Ping 
Published: July 2022

Abstract
In this work, we propose new statistical tools that are capable of characterizing the simultaneous dependence of dark matter and gas clustering on the scale and the density environment, and these are the environment-dependent wavelet power spectrum (env-WPS), the environment-dependent bias function (env-bias), and the environment-dependent wavelet cross-correlation function (env-WCC). These statistics are applied to the dark matter and baryonic gas density fields of the TNG100-1 simulation at redshifts of z=3.0-0.0, and to Illustris-1 and SIMBA at z = 0. The measurements of the env-WPSs suggest that the clustering strengths of both the dark matter and the gas increase with increasing density, while that of a Gaussian field shows no density dependence. By measuring the env-bias and env-WCC, we find that they vary significantly with the environment, scale, and redshift. A noteworthy feature is that at z = 0.0, the gas is less biased in denser environments of Δ ≳ 10 around 3 h Mpc−1, due to the gas reaccretion caused by the decreased AGN feedback strength at lower redshifts. We also find that the gas correlates more tightly with the dark matter in both the most dense and underdense environments than in other environments at all epochs. Even at z = 0, the env-WCC is greater than 0.9 in Δ ≳ 200 and Δ ≲ 0.1 at scales of k ≲ 10 h Mpc−1. In summary, our results support the local density environment having a non-negligible impact on the deviations between dark matter and gas distributions up to large scales.
A New Way to Explore Cosmological Tensions Using Gravitational Waves and Strong Gravitational Lensing

Abstract
In recent years, a crisis in the standard cosmology has been caused by inconsistencies in the measurements of some key cosmological parameters, the Hubble constant H
0 and cosmic curvature parameter Ω
K
, for example. It is necessary to remeasure them with the cosmological model-independent methods. In this paper, based on the distance sum rule, we present such a way to constrain H
0 and Ω
K
simultaneously in the late universe from strong gravitational lensing time-delay (SGLTD) data and gravitational wave (GW) standard siren data simulated from the future observation of the Einstein Telescope (ET). Based on the data for six currently observed SGLTDs, we find that the constraint precision of H
0 from the combined 100 GW events can be comparable with the measurement from the SH0ES collaboration. As the number of GW events increases to 700, the constraint precision of H
0 will exceed that of the Planck 2018 results. Considering 1000 GW events as the conservative estimation of ET in the 10 yr observation, we obtain H
0 = 73.69 ± 0.36 km s−1 Mpc−1 with a 0.5% uncertainty and

Médecins et infirmiers : leur nombre et leur rémunération en France et dans les autres pays de l’OCDE avant la pandémie
Authors: Lafortune Gaétan , Balestat Gaëlle 
Published: July 2022

Les débats sur les personnels de santé en France et dans les autres pays de l’Organisation de coopération et de développement économiques (OCDE) ont été dominés ces dernières décennies par la question des pénuries de main-d’œuvre et comment y remédier. En France, ces dix dernières années, les débats se sont concentrés plus particulièrement sur la question des « déserts médicaux », définis soit de manière large comme tout problème d’accès aux médecins ou aux hôpitaux dans certaines régions ou de manière plus spécifique comme des problèmes d’accès aux médecins généralistes. Cet article dresse un état des lieux de personnels de santé en France et dans les autres pays de l’OCDE en 2019 (juste avant la pandémie) et des évolutions au cours des vingt années précédentes, en se concentrant sur les médecins et les infirmiers. En France comme dans presque tous les pays de l’OCDE, le nombre de médecins et d’infirmiers par habitant a augmenté entre 2000 et 2019, mais à des rythmes différents et peut-être pas suffisamment pour répondre aux besoins croissants des populations vieillissantes, d’où des problèmes persistants de pénurie. Les politiques pour remédier aux problèmes de pénurie de main-d’œuvre passent par une augmentation de la formation et du recrutement de nouveaux médecins et d’infirmiers, ainsi que par une amélioration des conditions de travail et des rémunérations du personnel moins bien rémunéré pour accroître l’attractivité des emplois et réduire les départs. Cet article compare le niveau et l’évolution de la rémunération des médecins et des infirmiers en France et dans les autres pays de l’OCDE, tout en pointant les limites de la comparabilité des données disponibles.
Le NHS et le spectre de l’étatisation du système de santé français
Authors: Bras Pierre-Louis 
Published: July 2022

Le système de santé britannique, le National Health Service (NHS), sert régulièrement d’épouvantail en France ; les opposants aux mesures de régulation de notre système d’assurance maladie sont prompts à brandir le spectre de « l’étatisation » dont le NHS serait l’incarnation. Le NHS ne correspond pas à la caricature étatiste mise en avant dans certains discours. Les Britanniques restent très attachés à l’institution. Le système britannique est plus protecteur au plan financier que le français. Il affiche toutefois de moins bonnes performances sanitaires et pâtit d’un problème structurel de listes d’attente. Ces moindres performances, plutôt que de renvoyer à un effet système, sont à rapprocher des moindres ressources consacrées aux soins au Royaume-Uni. La crise Covid a considérablement aggravé les problèmes de temps d’attente au Royaume-Uni. Même si les conservateurs sont plutôt enclins à favoriser des politiques restrictives, le gouvernement a décidé d’augmenter les ressources allouées au NHS ; le niveau des dépenses de santé pourrait ainsi progressivement converger des deux côtés de la Manche.
L’invention de la lutte contre les rumeurs
Authors: Froissart Pascal 
Published: July 2022

Autant la rumeur n’a pas toujours existé en tant que concept scientifique, autant le contrôle de la rumeur est une invention du xx e siècle. Le 1 er mars 1942, une rubrique naît dans un quotidien des États-Unis, le Boston Herald, avec un nom programmatique : la « Clinique des rumeurs », conçue pour éradiquer le mal nouveau représenté par la diffusion des rumeurs de guerre. On pourrait croire qu’il s’agit d’une rubrique journalistique comme une autre, mais on découvre vite qu’elle est sous le patronage d’une organisation para-étatique et d’un comité de notables, et qu’elle a des caractéristiques singulières : un style mi-sérieux mi-populaire, un choix de sujets souvent anecdotiques, une révérence au « fait » et à la « source ». Sans le savoir, la Clinique des rumeurs pave la voie à l’émergence des rubriques et sites de fact-checking plusieurs décennies plus tard.
Genetic variation of sand flies (Diptera
Authors: Wijerathna Tharaka , Gunathilaka Nayana , Rodrigo Wasana 
Published: July 2022

Objective:
To identity the variation of sand flies in the Gampaha and Kurunegala districts of Sri Lanka and to assess DNA barcoding as a complementing method for morphological identification.

Methods:
A total of 38 441 sand flies were collected from selected localities in Gampaha and Kurunegala districts using standard entomological techniques from May 2017 to December 2018. Specimens were identified using morphological features and compared with mitochondrial cytochrome C oxidase subunit I gene- based DNA barcoding as an alternative tool.

Results:
Morphological and molecular identification confirmed the presence of four species under two genera (Phlebotomus and Sergentomyia). Phlebotomus argentipes was the predominant species, followed by Sergentomyia (S.) punjabensis, S. babu insularis, and an unidentified Sergentomyia sp. Phlebotomus argentipes showed a clear genetic differentiation from other species. S. babu insularis and S. punjabensis showed a higher genetic affinity to each other than the unidentified species. The unidentified Sergentomyia species is morphologically similar to S. zeylanica, but differs only in clavate gonostyle.

Conclusions:
DNA barcoding is an effective technique for the identification of sand flies. Further studies using molecular techniques will improve the knowledge of the cryptic diversity of Sri Lankan sand fly fauna. Establishing a reliable and standardized identification system for sand fly species in Sri Lanka is recommended.
