Recent innovations in mass spectrometry (MS) have led to the development of instruments with increased capabilities, smaller footprints, and relatively low cost. The traditional MS in most toxicology laboratories is a quadrupole system equipped with electron impact ionization. Recently, an ion trap with electron impact, positive chemical ionization, negative chemical ionization, and tandem MS c...

ISSUES Quality-management systems (QMS) are uncommon in clinical laboratories in Nigeria, and until recently, none of the nation's 5 349 clinical laboratories have been able to attain the certifications necessary to begin the process of attaining international accreditation. Nigeria's Human Virology Laboratory (HVL), however, began implementation of a QMS in 2006, and in 2008 it was determined ...

According to Landauer's Principle the annihilation (and presumably the creation) of one bit costs at least kT ln(2) much energy. This seems to imply that serial bit transmission is impossible; however, a complete quantum theory of communication should permit Alice to send Bob a message of arbitrary length, unknown to Bob in advance. One is lead to consider the Hilbert state space ∞ n=0 C 2 ⊗n ,...

Abstract The efficient resolution of optimization problems is one the key issues in today’s industry. This task relies mainly on classical algorithms that present scalability and processing limitations. Quantum computing has emerged to challenge these types problems. In this paper, we focus Metropolis-Hastings quantum algorithm, which based walks. We use algorithm build a software tool called M...

PURPOSE This study describes the creation and use of a web-based resource, designed to help nursing homes implement quality improvements through changes in staffing characteristics. DESIGN AND METHODS Information on staffing characteristics (i.e., staffing levels, turnover, stability, and use of agency staff), facility characteristics (e.g., ownership, size), and quality (i.e., quality measur...

We introduce quantum Markov states (QMS) in a general tree graph $$G= (V, E)$$ , extending the Cayley tree’s case. investigate property w.r.t. finer structure of considered tree. The main result present paper concerns diagonalizability locally faithful QMS $$\varphi $$ on UHF-algebra $${\mathcal {A}}_V$$ over by means suitable conditional expectation into maximal abelian subalgebra. Namely, ...

BACKGROUND Quality-assured tuberculosis laboratory services are critical to achieve global and national goals for tuberculosis prevention and care. Implementation of a quality management system (QMS) in laboratories leads to improved quality of diagnostic tests and better patient care. The Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has led to measurable improveme...
