Published: January 2020

Abstract –Using OPERA3DTM, the magnet poles’ shimming that provide an isochronous magnetic field in DECY-13 cyclotron was designed and calculated. The shimmed magnet poles as designed were placed in the magnet and the distribution of the magnetic field in the magnet axis direction (Bz) was measured in radial ( x and y) directions using 2 probes covering x=0 to 480 mm for one probe and 481 to 960 mm for the other, and y=0 to 960 mm, all were done at z=0 in 9 hours of scanning at 5 mm steps. This paper describes the interpolation and extrapolation to obtain data for magnetic field components (Bx, By,Bz) at 1 mm resolution and at z≠0 as required for beam tracking simulations. The tracking results are used to evaluate the distribution of the shimmed magnetic fields of DECY-13. The program for the interpolation and extrapolation was written and run using a free software Scilab 5.4.1, and tested against OPERA3DTM design data. The beam can reach final energy of 13 MeV when both data was applying in the beam tracking simulation.. However when the measured data was used, the final energy of the beam reached only 3 MeV, meaning that at the place where that energy was reached the magnetic field is no longer is of isochronous and the shimming of the magnetic poles’ must be improved or redesigned to reach the final beam energy of 13 MeV.Key words: isochronous, DECY-13 cyclotron, Scilab 5.4.1, interpolation and extrapolation, beam tracking simulation

Published: January 2020

Publikowane listy Ludwika Solskiego do córki – Anny Sosnowskiej (1905–1997) pochodzą z lat 1945–1954. Większość z nich aktor wysyłał z Krakowa, gdzie wtedy mieszkał, kilka z miast, w których przebywał na występach gościnnych (Warszawa, Bielsko) lub wypoczywał (Krynica, Morawin). Anna od 1945 przebywała za granicą. W Paryżu miała kłopoty ze znalezieniem stałej pracy, uczyła się stenografii. Solski pisze o warunkach życia w kraju, pogarszającym się zdrowiu, przekazach pieniężnych dla córki i paczkach od niej, przed którymi się wzbraniał. Towarzyszy mu ciągła troska o córkę. Listy i kartki pocztowe dotyczą przede wszystkim spraw prywatnych, ale dowiadujemy się z nich też wiele o pracy aktora, o objazdach z Grubymi rybami Bałuckiego po całym kraju i reakcjach publiczności, o uroczystościach jubileuszowych w 1951 i 1954. Korespondencja pokazuje pracę artysty teatralnego i funkcjonowanie teatru w Polsce w pierwszych latach powojennych. Listy Solskiej – matki do córki ogłosiła Lidia Kuchtówna (Listy Ireny Solskiej, Warszawa 1984). Teraz możliwa jest lektura listów obojga rodziców do Anny, kierowanych do Paryża. Zamieszczamy 61 listów. Oryginały (rękopisy, przeważnie z kopertami) znajdują się w Muzeum Teatru im. Henryka Tomaszewskiego we Wrocławiu. W 2015 pamiątki po Ludwiku i Irenie Solskich, wśród nich listy, podarował Muzeum Mathias von Poswik, wnuk brata Solskiej, który wszedł w ich posiadanie po śmierci Anny Sosnowskiej.

Published: January 2020

Background: Hemithioindigo is a promising molecular photoswitch that has only recently been applied as a photoswitchable pharmacophore for control over bioactivity in cellulo. Uniquely, in contrast to other photoswitches that have been applied to biology, the pseudosymmetric hemithioindigo scaffold has allowed the creation of both dark-active and lit-active photopharmaceuticals for the same binding site by a priori design. However, the potency of previous hemithioindigo photopharmaceuticals has not been optimal for their translation to other biological models.Results: Inspired by the structure of tubulin-inhibiting indanones, we created hemithioindigo-based indanone-like tubulin inhibitors (HITubs) and optimised their cellular potency as antimitotic photopharmaceuticals. These HITubs feature reliable and robust visible-light photoswitching and high fatigue resistance. The use of the hemithioindigo scaffold also permitted us to employ a para-hydroxyhemistilbene motif, a structural feature which is denied to most azobenzenes due to the negligibly short lifetimes of their metastable Z-isomers, which proved crucial to enhancing the potency and photoswitchability. The HITubs were ten times more potent than previously reported hemithioindigo photopharmaceutical antimitotics in a series of cell-free and cellular assays, and allowed robust photocontrol over tubulin polymerisation, microtubule (MT) network structure, cell cycle, and cell survival.Conclusions: HITubs represent a powerful addition to the growing toolbox of photopharmaceutical reagents for MT cytoskeleton research. Additionally, as the hemithioindigo scaffold allows photoswitchable bioactivity for substituent patterns inaccessible to the majority of current photopharmaceuticals, wider adoption of the hemithioindigo scaffold may significantly expand the scope of cellular and in vivo targets addressable by photopharmacology.

Abstract
Stars that escape globular clusters form tidal tails that are predominantly shaped by the global distribution of mass in the Galaxy, but also preserve a historical record of small-scale perturbations. Using deep grz photometry from DECaLS, we present highly probable members of the tidal tails associated with the evaporating globular cluster Palomar 5. These data yield the cleanest view of a stellar stream beyond ≈20 kpc and reveal: (1) a wide, low surface-brightness extension of the leading tail; (2) significant density variations along the stream; and (3) sharp changes in the direction of both the leading and the trailing tail. In the fiducial Milky Way model, a rotating bar perturbs the Palomar 5 tails and can produce streams with similar width and density profiles to those observed. However, the deviations of the stream track in this simple model do not match those observed in the Palomar 5 trailing tail, indicating the need for an additional source of perturbation. These discoveries open up the possibility of measuring the population of perturbers in the Milky Way, including dark-matter subhalos, with an ensemble of stellar streams and deep photometry alone.
Filling the Magnetospheres of Weak Pulsars
Authors: Chen Alexander Y. , Cruz Fábio , Spitkovsky Anatoly 
Published: January 2020

Abstract
Recent advances in numerical algorithms and computational power have enabled first-principles simulations of pulsar magnetospheres using particle-in-cell techniques. These ab initio simulations seem to indicate that pair creation through photon–photon collision at the light cylinder is required to sustain the pulsar engine. However, for many rotation-powered pulsars, pair creation operates effectively only near the stellar surface where magnetic field is high. How these “weak pulsars” fill their magnetospheres without efficient photon–photon pair conversion in the outer magnetosphere is still an open question. In this paper, we present a range of self-consistent solutions to the pulsar magnetosphere that do not require pair production near the light cylinder. When pair production is very efficient near the star, the pulsar magnetosphere converges to previously reported solutions. However, in the intermediate regime, where pair supply is barely enough to sustain the magnetospheric current, we observe a time-dependent solution with a quasi-period about half of the rotation period. This new quasi-periodic solution may explain the observed pulsar death line without invoking multipolar components near the star, and can potentially explain the core versus conal emission patterns observed in pulsar radio signals.
Condensation of Atomic Carbon: Possible Routes toward Glycine
Authors: Krasnokutski Serge A. , Jäger Cornelia , Henning Thomas 
Published: January 2020

Abstract
Many organic molecules including amino acids and nucleobases are expected to be formed in astrophysical environments. In this article, we used both experimental and computational approaches to test the possibility of the glycine formation in the interstellar medium via C atom addition to ice mantels of dust particles. The reactions of C atoms with NH3 and H2 were studied experimentally. These reactions are found to be highly exothermic and barrierless, leading to the formation of the products CH2NH and HCH. These product molecules are formed in excited states and therefore could immediately take part even in chemical reactions with energy barriers. The CH2NH molecule is formed in the long-lived triplet state, which is above the most energetically favorable singlet state of about 20,918 cm−1 (∼250 kJ mol−1). Therefore, based on the results of quantum chemical computations the following two pathways can take place at low temperature. The first one is C + H2 → HCH followed by NH3 + HCH + CO2 → glycine. The second one is C + NH3 → CH2NH followed by CH2NH + CO + H2O → glycine or CH2NH + CO2 + H2 → glycine. The first pathway was also tested experimentally by adding C atoms to ice clusters containing H2, NH3, and CO2 molecules. The detection of the main mass peak of glycine supported the feasibility of the proposed pathway.
HST/STIS Capability for Love Number Measurement of WASP-121b

Published: January 2020

Abstract
Data from transit light curves, radial velocity, and transit timing observations can be used to probe the interiors of exoplanets beyond the mean density, by measuring the Love numbers h
2 and k
2. The first indirect estimate of k
2 for an exoplanet from radial velocity and transit timing variation observations has been performed by taking advantage of the years-spanning baseline. Not a single measurement of h
2 has been achieved from transit light curves, mostly because the photometric precision of current observing facilities is still too low. We show that the Imaging Spectrograph instrument onboard the Hubble Space Telescope (HST) could measure h
2 of the hot Jupiter WASP-121b if only a few more observations were gathered. We show that a careful treatment of the noise and stellar limb darkening (LD) must be carried out to achieve a measurement of h
2. In particular, we find that the impact of the noise modeling on the estimation of h
2 is stronger than that of the LD modeling. In addition, we emphasize that the wavelet method for correlated noise analysis can mask limb brightening. Finally, using currently available data, we briefly discuss the tentative measurement of

in terms of interior structure. Additional observations would further constrain the interior of WASP-121b and possibly provide insights on the physics of inflation. The possibility of using the approach presented here with the HST provides a bridge before the high-quality data to be returned by the James Webb Space Telescope and PLATO telescope in the coming decade.
Inhibited Coagulation of Micron-size Dust Due to the Electrostatic Barrier

Published: January 2020

Abstract
The collisional evolution of solid material in protoplanetary disks is a crucial step in the formation of planetesimals, comets, and planets. Although dense protoplanetary environments favor fast dust coagulation, there are several factors that limit the straightforward pathway from interstellar micron-size grains to pebble-size aggregates. Apart from the grain bouncing, fragmentation, and fast drift to the central star, a notable limiting factor is the electrostatic repulsion of like-charged grains. In this study we aim at theoretical modeling of the dust coagulation coupled with the dust charging and disk ionization calculations. We show that the electrostatic barrier is a strong restraining factor to the coagulation of micrometer-size dust in dead zones of the disk (where the turbulence is suppressed). While the sustained turbulence helps to overcome the electrostatic barrier, low fractal dimensions of dust aggregates can potentially block their further coagulation even in this case. Coulomb repulsion may keep a significant fraction of small dust in the disk atmosphere and outer regions.
