Recombination Effects on Supernova Light Curves
Authors: Faran Tamar , Goldfriend Tomer , Nakar Ehud , Sari Re’em 
Published: June 2019

Abstract
The light curves of Type II supernovae (SNe II) are believed to be highly affected by recombination of hydrogen that takes place in their envelopes. In this work, we analytically investigate the transition from a fully ionized envelope to a partially recombined one and its effects on the SN light curve. The motivation is to establish the underlying processes that dominate the evolution at late times when recombination takes place in the envelope, yet early enough so that 56Ni decay is a negligible source of energy. We consider the diffusion of photons through the envelope while analyzing the ionization fraction and the coupling between radiation and gas and find that the main effect of recombination is on the evolution of the observed temperature. Before recombination, the temperature decreases relatively fast, while after recombination starts it significantly reduces the rate at which the observed temperature drops with time. This behavior is the main cause for the observed flattening in the optical bands, where for a typical red supergiant explosion the recombination wave affects the bolometric luminosity only mildly during most of the photospheric phase. Moreover, the plateau phase observed in some SNe II is not a generic result of recombination, and it also depends on the density structure of the progenitor. This is one possible explanation for the different light-curve decay rates observed in SNe II (P and L).
Using Surface Brightness Fluctuations to Study Nearby Satellite Galaxy Systems: Calibration and Methodology
Authors: Carlsten Scott G. , Beaton Rachael L. , Greco Johnny P. , Greene Jenny E. 
Published: June 2019

Abstract
We explore the use of ground-based surface brightness fluctuation (SBF) measurements to constrain distances to nearby dwarf galaxies. Using archival CFHT Megacam imaging data for a sample of 28 nearby dwarfs, we demonstrate that reliable SBF measurements and distances accurate to 15% are possible even for very low surface brightness (μ
0i
> 24 mag arcsec−2) galaxies with modest, ∼hour-long exposures with CFHT. Combining our sample with a recent sample of six dwarfs with SBF measured with Hubble Space Telescope (HST) from the literature, we provide the most robust empirical SBF calibration to date for the blue colors expected for these low-mass systems. Our calibration is credible over the color range 0.3 ≲ g − i ≲ 0.8 mag. It is also the first SBF calibration tied completely to tip of the red giant branch (TRGB) distances as each galaxy in the sample has a literature TRGB distance. We find that even though the intrinsic scatter in SBF increases for blue galaxies, the rms scatter in the calibration is still ≲0.3 mag. We verify our measurements by comparing with HST SBF measurements and detailed image simulations. We argue that ground-based SBF is a very useful tool for characterizing dwarf satellite systems and field dwarfs in the nearby, D ≲ 20 Mpc universe.
Helium Variation across Two Solar Cycles Reveals a Speed-dependent Phase Lag
Authors: Alterman B. L. , Kasper Justin C. 
Published: June 2019

Abstract
We study the relationship between the solar wind helium-to-hydrogen abundance ratio (A
He), solar wind speed (v
sw), and sunspot number (SSN) over solar cycles 23 and 24. This is the first full 22 year Hale cycle measured with the Wind spacecraft covering a full cycle of the solar dynamo with two polarity reversals. While previous studies have established a strong correlation between A
He and SSN, we show that the phase delay between A
He and SSN is a monotonic increasing function of v
sw. Correcting for this lag, A
He returns to the same value at a given SSN over all rising and falling phases and across solar wind speeds. We infer that this speed-dependent lag is a consequence of the mechanism that depletes slow wind A
He from its fast wind value during solar wind formation.
The Mass Function of Supermassive Black Holes in the Direct-collapse Scenario
Authors: Basu Shantanu , Das Arpan 
Published: June 2019

Abstract
One of the ideas that explains the existence of supermassive black holes (SMBHs) that are in place by z ∼ 7 is that there was an earlier phase of very rapid accretion onto direct-collapse black holes (DCBHs) that started their lives with masses ∼104–5

. Working in this scenario, we show that the mass function of SMBHs after such a limited time period, with growing formation rate paired with super-Eddington accretion, can be described as a broken power law with two characteristic features. There is a power law at intermediate masses whose index is the dimensionless ratio α ≡ λ/γ, where λ is the growth rate of the number of DCBHs during their formation era, and γ is the growth rate of DCBH masses by super-Eddington accretion during the DCBH growth era. A second feature is a break in the power-law profile at high masses, above which the mass function declines rapidly. The location of the break is related to the dimensionless number β = γ
T, where T is the duration of the period of DCBH growth. If the SMBHs continue to grow at later times at an Eddington-limited accretion rate, then the observed quasar luminosity function can be directly related to the tapered power-law function derived in this Letter.
Méfiance avec le soupçon ? Vers une étude du complot(isme) en sciences sociales
Authors: France Pierre 
Published: June 2019

Marronnier du journalisme autant qu’objet de préoccupations gouvernementales, le « complotisme » est un phénomène qui reste largement méconnu et fantasmé. Cet article aborde à la fois l’objet « théories du complot », ses multiples facettes et les hypothèses que l’on peut faire à son propos, mais en même temps les discours savants qui lui sont consacrés. Il s’agit ainsi de montrer que la critique des théories du complot n’est pas seulement un enjeu de connaissance, et surtout un enjeu politique, mais aussi un objet d’étude en soi et un corpus à analyser. L’article élargit aussi le débat à d’autres travaux universitaires laissés habituellement hors du champ de l’étude des théories du complot, notamment des travaux de science politique, dans un domaine dominé par la psychosociologie, la philosophie, et surtout l’expertise.

Abstract
Failure of the most recent tuberculosis (TB) vaccine trial to boost bacillus Calmette–Guérin–mediated anti-TB immunity despite the induction of Th1-specific central memory cell and effector memory cell responses highlights the importance of identifying optimal T cell targets for protective vaccines. In this study, we describe a novel, Mycobacterium tuberculosis–specific IFN-γ+CD4+ T cell population expressing surface markers characteristic of naive-like memory T cells (TNLM), which were induced in both human (CD45RA+CCR7+CD27+CD95−) and murine (CD62L+CD44−Sca-1+CD122−) systems in response to mycobacteria. In bacillus Calmette–Guérin–vaccinated subjects and those with latent TB infection, TNLM were marked by the production of IFN-γ but not TNF-α and identified by the absence of CD95 expression and increased surface expression CCR7, CD27, the activation markers T-bet, CD69, and the survival marker CD74. Increased tetramer-positive TNLM frequencies were noted in the lung and spleen of ESAT-61–20–specific TCR transgenic mice at 2 wk postinfection with M. tuberculosis and progressively decreased at later time points, a pattern not seen with TNF-α+CD4+ T cells expressing naive cell surface markers. Importantly, adoptive transfer of highly purified TNLM alone, from vaccinated ESAT-61–20–specific TCR transgenic mice, conferred equivalent protection against M. tuberculosis infection in the lungs of Rag−/− mice when compared with total memory populations (central and effector memory cells). Thus, TNLM may represent a memory T cell population that, if optimally targeted, may significantly improve future TB vaccine responses.
Transmission of Han Pictorial Motifs into the Western Periphery: Fuxi and Nüwa in the Wei-Jin Mural Tombs in the Hexi Corridor
Authors: Vampelj Suhadolnik Nataša 
Published: June 2019

This paper examines the ways in which Fuxi and Nüwa were depicted inside the mural tombs of the Wei-Jin dynasties along the Hexi Corridor as compared to their Han counterparts from the Central Plains. Pursuing typological, stylistic, and iconographic approaches, it investigates how the western periphery inherited the knowledge of the divine pair and further discusses the transition of the iconographic and stylistic design of both deities from the Han (206 BCE–220 CE) to the Wei and Western Jin dynasties (220–316). Furthermore, examining the origins of the migrants on the basis of historical records, it also attempts to discuss the possible regional connections and migration from different parts of the Chinese central territory to the western periphery. On the basis of these approaches, it reveals that the depiction of Fuxi and Nüwa in Gansu area was modelled on the Shandong regional pattern and further evolved into a unique pattern formed by an iconographic conglomeration of all attributes and other physical characteristics. Accordingly, the Shandong region style not only spread to surrounding areas in the central Chinese territory but even to the more remote border regions, where it became the model for funerary art motifs.

IntroductionIn this study, we aimed to distinguish differences in the procedural complication rate in a group of patients undergoing percutaneous coronary interventions (PCI) of the left main coronary artery (LMCA) between patients with isolated LMCA disease and multi-vessel disease (MVD) with LMCA involvement and to identify their predictors.Material and methodsWe assessed 221,187 patients from the Polish Cardiovascular Intervention Society national registry (ORPKI) regarding all PCI procedures performed in Poland in 2015 and 2016. We extracted data of 1,819 patients with isolated LMCA disease and 3,718 patients with MVD and LMCA involvement. We compared those two groups in terms of procedural complications and their predictors.ResultsThe overall rate of procedural complications was significantly higher in patients treated with LMCA PCI both in the group of patients with isolated LMCA (6.5%) and the group with MVD with LMCA involvement (7.3%) compared to the non-LMCA PCI group (1.9%, p = 0.002). Multivariate analysis confirmed that MVD with LMCA involvement is an independent predictor of decreased risk of procedural death in the overall group of patients undergoing PCI of the LMCA (odds ratio: 0.583; 95% confidence interval: 0.4–0.848; p = 0.005).ConclusionsThe MVD involvement in patients treated with PCI of the LMCA may play a protective role. Patients with isolated LMCA involvement undergoing PCI should be subjected to special care and protected by various methods, such as devices to support left ventricle function.

and vacuum-assisted biopsy – for diagnosing
and treating breast lesions

Published: June 2019

IntroductionThe vacuum-assisted biopsy (VAB) and the Breast Lesion Excision System (BLES) are minimally invasive biopsy techniques, both used as diagnostic and therapeutic tools. The aim of the study is to compare these two methods and assess them in the context of discomfort, early and late complications and their diagnostic and therapeutic potential.Material and methodsThe study involved 173 patients who underwent a VAB or a BLES breast biopsy in the period between 2009 and 2016. Approximately 3 months after the biopsy, the patients completed a questionnaire in which they assessed the procedure for discomfort associated with the procedure and the final cosmetic outcome. The cosmetic effect of the biopsy was also assessed by a surgeon.ResultsThe BLES and the VAB breast biopsies did not differ in terms of pain, duration, and discomfort of the procedure, breast bruising, breast tenderness about 24 h after the procedure or pain lasting over 3 months after the biopsy. Subsequently, the biopsies were evaluated in terms of the cosmetic effect assessed by the patient and by a surgeon and no differences were observed. There were no significant differences between the VAB and the BLES breast biopsies in the course of the procedure, early and late complications and cosmetic effect.ConclusionsSince the BLES breast biopsy makes it possible to evaluate the margins, it is a good alternative to the open breast biopsy.
The Abbreviated Psychopathy Measure-2: associations with normal-range and maladaptive personality traits
Authors: Semel Robert A. 
Published: June 2019

BackgroundThe aim of the study was to validate an updated form of the Abbreviated Psychopathy Measure which is based on the triarchic model of psychopathy. Revisions were made to improve indexing of the triarchic scales. The study focused on examining the relationships between the APM-2 scales with lower-order personality traits associated with psychopathy, as well as with antiso-cial intent, a correlate of antisocial behavior.Participants and procedureA convenience sample of participants (N = 190) was recruited from Amazon’s Mechanical Turk (MTurk). Construct validity of the APM-2 scales was examined using Pearson’s r correlation and multiple regression analyses to determine the relationships between APM-2 scales and criterion measures.ResultsThe APM-2 Total score was associated at moderate to high levels with core personality features associated with psychopathy. APM-2 Boldness was associated with both positive adjustment (social potency, emotional stability), and negative adjustment (both dangerous and calculated sensation seeking). APM-2 Meanness was associated with measures of callousness, hostile aggression, and manipulativeness, as well as with a measure of antisocial intent. APM-2 Disinhibition was associated with measures of impulsive, norm violating behavior, negative emotional disposition, and antisocial intent.ConclusionsThe associations between APM-2 scales and personality traits replicated certain key findings reported in the literature regarding psychopathy-relevant traits indexed by the Triarchic Psychopathy Measure (TriPM). Thus, this study provides a preliminary indication, albeit with a limited range of personality and antisocial behavior variables, that the nomological networks of the APM-2 scales may parallel the nomological networks of the TriPM scales.
The Polish Community of Greenpoint, Brooklyn, Then and Now: A View from the Street
Authors: DeSena Judith N. 
Published: June 2019

Abstract
This article examines the changes that have occurred in Greenpoint, Brooklyn, throughout the years. Greenpoint became home to many Polish immigrants who sought economic opportunities in the U.S. and who wanted to escape from Soviet-era political unrest. Greenpoint became known as “Little Warsaw.” With economic restructuring in the U.S. and globalization, Greenpoint was affected. Factories and industrial work employing the Polish and working-class community was replaced by a service economy. The latest trend is gentrification and large scale, luxury development. The Polish community, to a large extent, has been priced-out. Polish retail, entertainment venues, and event spaces have also diminished because of dramatic commercial rent increases and shrinking population. The Polish community is found re-establishing itself in more affordable neighborhoods of New York City.

Leidt terugtred van de wetgever tot een opmars van rechterlijke rechtsvorming en afbraak van democratische waarden?
Recentelijk heeft de Raad van State gewaarschuwd dat het primaat van de wetgever wordt uitgehold door het regeren bij akkoord, gebruik van kaderwetgeving, experimentwetgeving en private regelgeving. Dat zou leiden tot een opmars van rechtsvorming door de rechter waardoor het primaat van de wetgever nog verder wordt aangetast. In deze bijdrage wordt echter verdedigd dat herstel van het primaat van de wetgever waarschijnlijk onmogelijk is en dat een grotere nadruk op rechterlijke rechtsvorming in het licht van de democratietheorie van Rosanvallon evengoed kan worden gezien als een zegen voor de democratie.
Automatic Date Fruit Recognition Using Outlier Detection Techniques and Gaussian Mixture Models

Published: June 2019

In this paper, we propose a method for automatically recognizing different date varieties. The presence of outlier samples could significantly degrade the recognition outcomes. Therefore, we separately prune samples of each variety from outliers using the Pruning Local Distance-based Outlier Factor (PLDOF) method. Samples of the same variety could have several visual appearances because of the noticeable variation in terms of their visual characteristics. Thus, in order to take this intra-variation into account, we model each variety with a Gaussian Mixture Model (GMM), where each component within the GMM corresponds to one visual appearance. Expectation-Maximization (EM) algorithm was used for parameters estimation and Davies-Bouldin index was used to automatically and precisely estimate the number of components (i.e., appearances). Compared to the related studies, the proposed method 1) is capable to recognize samples though the noticeable variation, in terms of maturity stage and hardness degree, within some varieties; 2) achieves a high recognition rate in spite of the presence of outlier samples; 3) is capable to distinguish between the highly confusing varieties; 4) is fully automatic, as it does not require neither physical measurements nor human assistance. For testing purposes, we introduce a new benchmark which includes the highest number of varieties (11) compared to the previous studies. Experiments show that our method has significantly outperformed several methods, where a high recognition rate of 97.8% has been reached.

Published: June 2019

This paper presents a salt-and-pepper noise removal scheme using modified mean filter. The proposed method is based on a simple basic concepts of mean filter, where each mean value is calculated from the mathematical formula of interquartile range (IQR). It replaces the noisy pixels using IQR based mathematical formula applied on the filter window. Experimental results are presented to demonstrate the efficiency (quality of the image) of the method compared to other existing different types of impulse noise removal techniques.
