The languages accepted by finite automata are precisely the languages denoted by regular expressions. In contrast, finite automata may exhibit behaviours that cannot be described by regular expressions up to bisimilarity. In this paper, we consider extensions of the theory of regular expressions with various forms of parallel composition and study the effect on expressiveness. First we prove th...

This article looks into the concept of Buddha-nature in Maṇi bka’ ’bum, a revealed text (gter ma) ascribed to ancient Tibetan king Srong bstan sgam po, who is considered an incarnation Bodhisattva Avalokiteśvara, tutelary deity Tibet. There are two main technical terms that designate this text. One well-known bde bar gshegs pa’i snying used express idea all sentient beings have Buddha-nature, w...

Progressive cardiac remodeling is characterized by subsequent chamber hypertrophy, enlargement, and pump dysfunction. It is also associated with increased cardiac fibrosis and matrix turnover. Interestingly, peroxisome proliferator-activated receptor (PPAR) activators reduce cardiac hypertrophy, inflammation, and fibrosis. Little is known about the role of fenofibrates in mediating PPAR -indepe...

INTRODUCTION To determine the tobacco industry's policy and action with respect to radioactive polonium 210 ((210)Po) in cigarette smoke and to assess the long-term risk of lung cancer caused by alpha particle deposits in the lungs of regular smokers. METHODS Analysis of major tobacco industries' internal secret documents on cigarette radioactivity made available online by the Master Settleme...

OBJECTIVES Lack of routine patient's nutritional assessment and prescription of long fasting periods throughout the perioperative period are still widely prevalent despite the advances in surgical care. Therefore, the aim of this study was to assess nutritional routines in two surgical wards. METHODS Adult patients undergoing laparotomy at two distinct units (gastrointestinal and gynecologic)...

‎‎‎In this paper‎, ‎the‎ notion of injectivity with respect to order dense embeddings in ‎‎the category of $S$-posets‎, ‎posets with a monotone action of a‎ pomonoid $S$ on them‎, ‎is studied‎. ‎We give a criterion‎, ‎like the Baer condition for injectivity of modules‎, ‎or Skornjakov criterion for injectivity of $S$-sets‎, ‎for the order dense injectivity‎. ‎Also‎, ‎we consider such injectivit...

For an algebraic number field K with ring of integers $$\mathcal {O}_{K}$$ , important subgroup the ideal class group $$Cl_{K}$$ is Pólya group, denoted by Po(K), which measures failure -module $$Int(\mathcal {O}_{K})$$ integer-valued polynomials on from admitting a regular basis. In this paper, we prove that for any integer $$n \ge 2$$ there are infinitely many totally real bi-quadratic fields...
