BACKGROUND For evaluation of jaundiced neonates, serum bilirubin (SB) or transcutaneous bilirubinometry (TcB) is used. Few data are available on the quantitative reduction of blood sampling by using TcB. METHODS We conducted a randomized controlled trial in hospitalized jaundiced neonates ≥32 weeks' gestational age. In the intervention group, TcB was used and in the control group the decision...

BACKGROUND Supraclavicular (SC) lymph node metastases are important in the analysis of thoracic malignancies for staging as well as for diagnosing purposes. Ultrasound (US) guidance visualises lesions very precisely, enabling tissue biopsies in real-time mode. OBJECTIVES To report on the diagnostic qualities of SC tissue core biopsies (TCB). METHODS A retrospective database analysis was per...

Natural phytoplankton assemblages from an offshore station in Lake Michigan were exposed to individual isomers of trichlorobenzene (TCB) and incubated in situ for a 24 h period. One set of exposures was initiated with a lake assemblage collected at 0330 h from 30 m and the TCB isomers added at 0400 h. The second exposure experiment was initiated with an assemblage from 30 m collected at 1530 h ...

OBJECTIVE To assess the utility of 24 and 48 hours transcutaneous bilirubin (TcB) index for predicting subsequent significant hyperbilirubinemia in healthy term neonates. METHODS TcB indices were obtained for healthy, breastfed, term AGA newborns at 24 +/- 2, 48 +/- 2 and subsequently at intervals of 24 hours. Neonates with illness, on treatment and positive Direct Coomb's test were excluded....

A simple atomic relay function is proposed as a minimal trusted computing base (TCB) for a domain name system (DNS) server. This TCB, composed of a fixed sequence of logical and cryptographic hash operations, can be amplified to ensure that a DNS server cannot violate rules. The paper also outlines elements of a TCB-DNS protocol that amplifies the simple TCB to secure the domain name system. Th...

Real-time behavior is specified in compliance with timeliness requirements, which in essence calls for synchronous system models. However, systems often rely on unpredictable and unreliable infrastructures, that suggest the use of asynchronous models. Several models have been proposed to address this issue. We propose an architectural construct that takes a generic approach to the problem of pr...

A new homogenization technique, the temperature-related Cauchy–Born (TCB) rule, is proposed in this paper with the consideration of the free energy instead of the potential energy. Therefore, temperature effects at the nanoscale can be investigated using continuum approximation with the implementation of the TCB rule. The TCB rule is verified via stress analyses of several crystalline solids. T...

BACKGROUND: For evaluation of jaundiced neonates, serum bilirubin (SB) or transcutaneous bilirubinometry (TcB) is used. Few data are available on the quantitative reduction of blood sampling by using TcB. METHODS: We conducted a randomized controlled trial in hospitalized jaundiced neonates ≥32 weeks’ gestational age.

OBJECTIVE The objective of this study was to determine whether transcutaneous bilirubin (TcB) measurements correlate with serum total bilirubin (STB) levels in indigenous, darkly pigmented African newborns with varying degrees of skin pigmentation, some of which had developed kernicterus. METHODS Jaundiced infants who were < or =2 weeks of age and admitted to Baptist Medical Center-Eku (Eku; ...

A transfer guard built on a high-assurance multilevel secure (MLS) trusted computing base (TCB) must be a trusted subject with the capability to perform downgrades not otherwise permitted by the MLS security policy. Formal evaluations of MLS systems containing trusted subjects are complicated when the trusted subjects are evaluated as part of a monolithic TCB. While welldeveloped techniques of ...
