Near-infrared Spectral Features in Single-aged Stellar Populations

Synthetic spectra for single-aged stellar populations of metallicities [M/H] = -0.5, 0.0 and +0.5, ages = 3 to 17 Gyrs, and initial mass function exponents x = 0.1 to 2.0 were built in the wavelength range 6000-10200 Angstrons. For such we have employed the grid of synthetic spectra described in Schiavon & Barbuy (1999), computed for the stellar parameters 2500 <= Teff <= 6000 K, -0.5 <= log g <= 5.0, [M/H] = -0.5, 0.0 and +0.5, and [alpha/Fe] = 0.0, together with the isochrones by Bertelli et al. (1994) and Baraffe et al. (1998). The behavior of the features NaI8190, CaII8662, TiO6600 and FeH9900 in the integrated spectra of single stellar populations were studied in terms of metallicity, initial mass function and age variations. The main conclusions are that the NaI doublet is an IMF-sensitive feature, which is however sensitive also to metallicity and age, whereas TiO, CaII and FeH are very sensitive to metallicity and essentially insensitive to IMF and age.Comment: 13 pages + 7 figures, ApJ accepte

Varian Semantik pada Bentuk Duplet yang Tersebar di Wilayah Pemakaian Kabupaten Brebes

Wahyuni, Nur Eka. “Semantic variant of the duplet form spread over the area of use of brebes district”. Skripsi (S1) Study Programe of Indonesian Literature, Faculty of Humanities, Universitas Diponegoro. Mentor: I. Dr. M. Suryadi, M.Hum. II. Drs. Suharyo, M.Hum. [email protected]. August 2017. The purpose of this study to describe the semantic variant of doublet form Javanese Brebes and Sundanese Brebes. In this study the authors take two districts as a sample of research areas consisting of the district of Banjarharjo and Ketanggungan. Data collection methods in this research is a method of referring to the technique of record and record, as well as the method of abilities with interview techniques as research instruments. Data analysis method is descriptive qualitative. The theory used in this research is duplet theory and sociodialektologi theory. The result of this research is finding the form of doublet of Java Language Brebes and Sundanese Brebes which is based on variant, that is (1) doublet based on area spread, covering area of Sundanese language, transition and Javanese language, (2) doublet based on form, duplet absolute-synonym and doublet absolute-homonyms, (3) doublet based on etymon, the doublet relics. Keywords: doublet, Javanese Brebes, Sundanese Brebes

Multiple chiral doublet candidate nucleus 105^{105}Rh in a relativistic mean-field approach

Following the reports of two pairs of chiral doublet bands observed in $^{105}$Rh, the adiabatic and configuration-fixed constrained triaxial relativistic mean-field (RMF) calculations are performed to investigate their triaxial deformations with the corresponding configuration and the possible multiple chiral doublet (M$\chi$D) phenomenon. The existence of M$\chi$D phenomenon in $^{105}$Rh is highly expected.Comment: 10 pages, 3 figure

Canceling Quadratic Divergences in a Class of Two-Higgs-Doublet Models

The Newton-Wu conditions for the cancellation of quadratic divergences in a class of two-Higgs-doublet models are analyzed as to how they may be satisfied with a typical extension of the Standard Model of particle interactions.Comment: 5 pages, no figur

New supersymmetric flux vacua of type II string theory and Generalized Complex Geometry

We study Minkowski supersymmetric flux vacua of type II string theory. Based on the work by M. Grana, R. Minasian, M. Petrini and A. Tomasiello, we briefly explain how to reformulate things in terms of Generalized Complex Geometry, which appears to be a natural framework for these compactifications. In particular, it provides a mathematical characterization of the internal manifold, and one is then able to find new solutions, which cannot be constructed as usual via T-dualities from a warped T^6 solution. Furthermore, we discuss how, thanks to a specific change of variables, one can ease the resolution of the orientifold projection constraints pointed out by P. Koerber and D. Tsimpis. One is then able to find new solutions with intermediate SU(2) structure.Comment: Contribution to the proceedings of the 4th EU RTN Workshop (09/2008, Varna, Bulgaria), 7 page

Characterisation of a Thin Fully Depleted SOI Pixel Sensor with High Momentum Charged Particles

This paper presents the results of the characterisation of a thin, fully depleted pixel sensor manufactured in SOI technology on high-resistivity substrate with high momentum charged particles. The sensor is thinned to 70 $\mu$m and a thin phosphor layer contact is implanted on the back-plane. Its response is compared to that of thick sensors of same design in terms of signal and noise, detection efficiency and single point resolution based on data collected with 300 GeV pions at the CERN SPS. We observe that the charge collected and the signal-to-noise ratio scale according to the estimated thickness of the sensitive volume and the efficiency and single point resolution of the thinned chip are comparable to those measured for the thick sensors.Comment: 8 pages, 3 figures, submitted to Nucl.

IDM and not only

In this note, we discuss recent updates to a previous scan for the Inert Doublet Model, a two Higgs doublet model with a dark matter candidate. We explicitly show the inclusion of updated constraints on direct detection reduces the allowed parameter space significantly. We furthermore discuss the IDMS - an extension of the IDM with a complex singlet.Comment: 12 pages, 7 figures; Contribution to Corfu Summer Institute 2016 "School and Workshops on Elementary Particle Physics and Gravity", 31 August - 23 September, 2016, Corfu, Greec
