All the Elephants Faced the Door: Fiction and poetry

All the Elephants Faced the Door is a collection of fiction and poetry. The first section, “The World is Nice to Butterflies,” is a collection of six short stories. The collection focuses on the Solis family. The family consists of six sisters and the stories follow their journey of falling in love, forming romantic relationships and the eventuality of marriage. The second half of my manuscript is composed of poems and is divided in three sections. The first, “The Stuff of the World is Love-Stuff,” is a sequence of love poems. The second section entitled, “Domestic Anxiety,” is a series of poetry addressing women\u27s issues. One of the main themes is the fear or hatred of housework and the fear of a woman losing her identity because she is domesticated. The concluding section, “Are You Looking at Me?,” is a series of identity poems that attempt to define who I am and where I come from. A woman\u27s fear of losing herself and her identity when entering into a relationship is the main theme found in All the Elephants Faced the Door

On a revisited Moore-Penrose inverse of a linear operator on Hilbert spaces

[EN] For two given Hilbert spaces H and K and a given bounded linear operator A is an element of L(H, K) having closed range, it is well known that the Moore-Penrose inverse of A is a reflexive g-inverse G is an element of L ( K; H) of A which is both minimum norm and least squares. In this paper, weaker equivalent conditions for an operator G to be the Moore-Penrose inverse of A are investigated in terms of normal, EP, bi-normal, bi-EP, l-quasi-normal and r-quasi-normal and l-quasi-EP and r-quasi-EP operators.Research partially supported by Ministerio de Economia y Competitividad of Spain (grant DGI MTM2013-43678-P and Red de Excelencia MTM2015-68805-REDT)Malik, SB.; Thome, N.

The class of m-EP and m-normal matrices

The well-known classes of EP matrices and normal matrices are de- fined by the matrices that commute with their Moore-Penrose inverse and with their conjugate transpose, respectively. This paper investigates the class of m-EP matrices and m-normal matrices that provide a generalization of EP matrices and normal matrices, respectively, and analyzes both of them for their properties and characterizations.Third author was partially supported by Ministerio de Economia y Competitividad of Spain [grant number DGI MTM2013-43678-P], [Red de Excelencia MTM2015-68805-REDT].Malik, SB.; Rueda, L.; Thome, N.

Calibration of the Thermal Infrared Sensor on the Landsat Data Continuity Mission

The Landsat series of satellites provides the longest running continuous data set of moderate-spatial-resolution imagery beginning with the launch of Landsat 1 in 1972 and continuing with the 1999 launch of Landsat 7 and current operation of Landsats 5 and 7. The Landsat Data Continuity Mission (LDCM) will continue this program into a fourth decade providing data that are keys to understanding changes in land-use changes and resource management. LDCM consists of a two-sensor platform comprised of the Operational Land Imager (OLI) and Thermal Infrared Sensors (TIRS). A description of the applications and design of the TIRS instrument is given as well as the plans for calibration and characterization. Included are early results from preflight calibration and a description of the inflight validation

Feigning ADHD and stimulant misuse among Dutch university students

The increasing number of university students seeking diagnosis of attention-deficit/hyperactivity disorder (ADHD), and findings of an increased stimulant misuse among university students, has raised concerns regarding the credibility of the symptoms of those students. However, most of our current knowledge refers to university students in North America and less is known about this issue on European campuses. The present survey aimed to collect opinions on feigning ADHD and to estimate the prevalence of stimulant misuse among 1071 university students in the Netherlands. The majority of students expressed liberal attitudes towards feigning ADHD. Also, a substantial number of respondents considered feigning ADHD themselves or know someone who feigns ADHD. Furthermore, 68% of students assumed benefits of taking stimulants without prescription and 16% have indeed already taken stimulants without prescription. Feigning ADHD and misuse of prescription medication are prevalent issues among Dutch students. The results underline the need for a careful diagnostic evaluation of individuals for ADHD. Furthermore, efforts are required in order to prevent stimulant drug trafficking and misuse among university students

On a new generalized inverse for matrices of an arbitrary index

[EN] The purpose of this paper is to introduce a new generalized inverse, called DMP inverse, associated with a square complex matrix using its Drazin and Moore-Penrose inverses. DMP inverse extends the notion of core inverse, introduced by Baksalary and Trenkler for matrices of index at most 1 in (Baksalary and Trenkler (2010) [1]) to matrices of an arbitrary index. DMP inverses are analyzed from both algebraic as well as geometrical approaches establishing the equivalence between them. (C) 2013 Elsevier Inc.

Further properties on the core partial order and other matrix partial orders

This paper carries further the study of core partial order initiated by Baksalary and Trenkler [Core inverse of matrices, Linear Multilinear Algebra. 2010;58:681-697]. We have extensively studied the core partial order, and some new characterizations are obtained in this paper. In addition, simple expressions for the already known characterizations of the minus, the star (and one-sided star), the sharp (and one-sided sharp) and the diamond partial orders are also obtained by using a Hartwig-Spindelbck decomposition.This author was partially supported by Ministry of Education of Spain [grant number DGI MTM2010-18228] and by Universidad Nacional de La Pampa, Argentina, Facultad de Ingenieria [grant number Resol.

Opportunities to Intercalibrate Radiometric Sensors From International Space Station

Highly accurate measurements of Earth's thermal infrared and reflected solar radiation are required for detecting and predicting long-term climate change. We consider the concept of using the International Space Station to test instruments and techniques that would eventually be used on a dedicated mission such as the Climate Absolute Radiance and Refractivity Observatory. In particular, a quantitative investigation is performed to determine whether it is possible to use measurements obtained with a highly accurate reflected solar radiation spectrometer to calibrate similar, less accurate instruments in other low Earth orbits. Estimates of numbers of samples useful for intercalibration are made with the aid of year-long simulations of orbital motion. We conclude that the International Space Station orbit is ideally suited for the purpose of intercalibration

Studies of multiplicity in relativistic heavy-ion collisions

In this talk I'll review the present status of charged particle multiplicity measurements from heavy-ion collisions. The characteristic features of multiplicity distributions obtained in Au+Au collisions will be discussed in terms of collision centrality and energy and compared to those of p+p collisions. Multiplicity measurements of d+Au collisions at 200 GeV nucleon-nucleon center-of-mass energy will also be discussed. The results will be compared to various theoretical models and simple scaling properties of the data will be identified.Comment: "Focus on Multiplicity" Internationsl Workshop on Particle Multiplicity in Relativistic Heavy Ion Collisions, Bari, Italy, June 17-19, 2003, 16 pages, 15 figure
