Phaseolus vulgaris leuco-agglutinin immunohistochemistry. A comparison between autoradiographic and lectin tracing of neuronal efferents

The autoradiographic pattern of anterograde labeling as a result from injections with tritiated amino acids is compared to the labeling of efferents with Phaseolus vulgaris leuco-agglutinin after lectin injections in the same nucleus visualized by immunohistochemical methods. This comparison is made for efferents from the ventromedial hypothalamic nucleus to the amygdaloid body.

An introduction to description logics and query rewriting

This chapter gives an overview of the description logics underlying the OWL 2 Web Ontology Language and its three tractable profiles, OWL 2 RL, OWL 2 EL and OWL 2 QL. We consider the syntax and semantics of these description logics as well as main reasoning tasks and their computational complexity. We also discuss the semantical foundations for fist-order and datalog rewritings of conjunctive queries over knowledge bases given in the OWL2 profiles, and outline the architecture of the ontology-based data access system Ontop

Neurodevelopmental outcome at 5.5 years in Dutch preterm infants born at 24-26 weeks' gestational age: the EPI-DAF study

Objective After lowering the Dutch threshold for active treatment from 25 to 24 completed weeks' gestation, survival to discharge increased by 10% in extremely preterm live born infants. Now that this guideline has been implemented, an accurate description of neurodevelopmental outcome at school age is needed.Design Population-based cohort study.Setting All neonatal intensive care units in the Netherlands.Patients All infants born between 24(0/7) and 26(6/7 )weeks' gestation who were 5.5 years' corrected age (CA) in 2018-2020 were included.Main outcome measures Main outcome measure was neurodevelopmental outcome at 5.5 years. Neurodevelopmental outcome was a composite outcome defined as none, mild or moderate-to-severe impairment (further defined as neurodevelopmental impairment (NDI)), using corrected cognitive score (Wechsler Preschool and Primary Scale of Intelligence Scale-III-NL), neurological examination and neurosensory function. Additionally, motor score (Movement Assessment Battery for Children-2-NL) was assessed. All assessments were done as part of the nationwide, standardised follow-up programme.Results In the 3-year period, a total of 632 infants survived to 5.5 years' CA. Data were available for 484 infants (77%). At 5.5 years' CA, most cognitive and motor (sub)scales were significantly lower compared with the normative mean. Overall, 46% had no impairment, 36% had mild impairment and 18% had NDI. NDI-free survival was 30%, 49% and 67% in live born children at 24, 25 and 26 weeks' gestation, respectively (pDevelopmen

Fundamental functions in equilibrium thermodynamics

In the standard presentations of the principles of Gibbsian equilibrium thermodynamics one can find several gaps in the logic. For a subject that is as widely used as equilibrium thermodynamics, it is of interest to clear up such questions of mathematical rigor. In this paper it is shown that using convex analysis one can give a mathematically rigorous treatment of several basic aspects of equilibrium thermodynamics. On the basis of a fundamental convexity property implied by the second law, the following topics are discussed: thermodynamic stability, transformed fundamental functions (such as the Gibbs free energy), and the existence and uniqueness of possible final equilibrium states of closed composite thermodynamic systems. It is shown that a standard mathematical characterization of thermodynamic stability (involving a positive definiteness property) is sufficient but in fact not necessary for the physically superior convexity characterization of thermodynamic stability. Furthermore, it is found that functions such as the Gibbs free energy can be rigorously and globally defined using convex conjugation instead of Legendre transformation. Another result desribed in this paper is that equilibrium thermodynamics cannot always uniquely predict possible final equilibrium states of closed composite thermodynamic systems

OWL-Full Reasoning from an Object Oriented Perspective

Bridging the gap between OWL and Object-Oriented Programming (OOP) languages is an indispensable condition to enable the Object-Oriented Modeling in Software Engineering by OWL. However it is very difficult in case of static OOP languages like Java and C#. We have developed SWCLOS, which is an OWL processor seamlessly built on top of Common Lisp Object System (CLOS), a dynamic OOP language. SWCLOS allows programmers to develop application domain models by OWL and enables OOP upon the models. In this paper, we explain the semantic gap between OWL and OOP languages, introduce the RDFS and OWL realization at SWCLOS, and discuss the OWL features from OOP perspectives. Finally we demonstrate the OWL-Full level performance in SWCLOS

Improvement of the performance of a u-metal magnetically shielded room by means of active compensation

An active compensation technique is presented for improving the performance of a mu -metal magnetically shielded room. Active compensation is established by measuring the magnetic field inside the room by a SQUID magnetometer. The output of this sensor is amplified and connected to a coil surrounding the room. The magnetic field generated in this way compensates the measured field inside the room. Active compensation was tested for magnetic fields in the vertical direction in a shielded room with one mu -metal shield. At low frequencies a shielding improvement of typically 40 dB was obtained. Measurements performed on a room with two mu -metal shields indicated that the attainable improvement is not limited by the amount of mu -metal applied in the room. The active compensation set-up is described in detail and experiments performed on the two magnetically shielded rooms are presented and discussed
