We construct an explicit representation of the Sugawara generators for arbitrary level in terms of the homogeneous Heisenberg subalgebra, which generalizes the well-known expression at level 1. This is achieved by employing a physical vertex operator realization of the affine algebra at arbitrary level, in contrast to the Frenkel– Kac–Segal construction which uses unphysical oscillators and is ...

The Rosenberg Self-Esteem Scale is the most widely used instrument to assess self-esteem. In light of the absence of adaptations in Colombia, this study seeks to validate and adapt this scale in the Colombian population, and perform factorial equivalence with the Spanish version. A total of 1,139 seniors (633 Colombians and 506 Spaniards) were evaluated; the individuals answered the Rosenberg S...

We conducted a 9-month prospective cohort study of 2,527 patients with systemic inflammatory response syndrome in three intensive care units and three general wards in a tertiary health care institution. Markov models were developed to predict the probability of movement to and from more severe stages--sepsis, severe sepsis, or septic shock--at 1, 3, and 7 days. For patients with sepsis, severe...

In this work, dust properties around the White Dwarf PG 1225-079 located at RA (J2000): 12h 27m 47.35s, DEC(J2000): -08° 14’ 37.97” is studied extensively using publicly available data from Improved Reprocessing of IRAS Survey (IRIS), AKARI infrared survey and Wide field Infrared Explorer (WISE). The bipolar structure hardly resolved in IRIS (60 μm 100 μm) clearly (90 140 WISE (12 22 images. co...

OBJECTIVE: This study involves the initial validation of the Short Schema Mode Inventory (SMI) in Italy. A total of 109 Axis II patients and 241 controls participated in the study. METHOD: Confirmatory factor analysis on SMI data to evaluate a measurement model of 14 factors using LISREL 8.80 was performed. Assessment of fit was based on CFI, NNFI, SRMR, RMSEA and Chi-square/df ratio. Reliabili...

Abstract Sitotroga cerealella (Oliv.) (Lepidoptera: Gelechiidae) is one of the most important post-harvest pests maize Zea mays L. Some Mexican races ( Z. ) could be a novel source resistance against S. to improve commercial varieties, lines and hybrids. We studied races, recollected at Chihuahua State . focused on antibiosis tolerance Cristalino-079 race shows low level consumption in grams pe...
