Presenting a 15 sec. pulsed tone, the conditional stimulus (CS+), followed by ½ sec. tail shock to a well-trained rat causes a sudden, but transient, pressor response (C 1). Blood pressure (BP) then drops before increasing again (C 2). A steady tone of the same frequency never followed by a shock (a discriminative stimulus, or CS-) evokes a C 1 , but not a C 2 response. Experiment 1 tests the h...

On line analytical processing (OLAP) is an essential element of decisionsupport systems. OLAP tools provide insights and understanding needed for improved decision making. However, the answers to OLAP queries can be biased and lead to perplexing and incorrect insights. In this paper, we propose HypDB, a system to detect, explain, and to resolve bias in decision-support queries. We give a simple...

We derive normal approximation bounds in the Kolmogorov distance for random variables possessing decompositions of Barbour, Karoński, and Ruciński (J. Combin. Theory Ser. B 47 (1989) 125–145). highlight example standardized subgraph counts Erdős–Rényi graph. prove a bound by generalizing argumentation Röllin (Probab. Engrg. Inform. Sci. (2022) 747–773), who used Stein–Tikhomirov method to speci...

A commercial yeast culture feed supplement (YC; Celmanax SCP, Vi-COR, Mason City, IA) was provided to turkeys throughout a 16-wk grow-out to determine if it would prevent the effects of stress on production and pathogen colonization. The YC was provided either continuously at 100 g/t (YC-CS) or intermittently during times of stress at 200 g/t (YC-IS). Birds were stressed with an environmental c...

Developing inexpensive and highly efficient non-precious-metal electrocatalysts has been proposed as a promising alternative to platinum-based catalysts for the hydrogen evolution reaction (HER). Herein, we report novel FeP NPs supported on inexpensive and available candle soot (FeP-CS) derived from Fe3O4-CS hybrid precursors obtained after a phosphidation reaction. As HER electrocatalysts, the...

This paper briefly describes a technique for improving capacity and operational stability of busy mainline junctions and stations. The technique, called the SafeCap advisory system, employs a mixture of existing train monitoring and control technologies to introduce an advisory control layer on top of fixed-block signalling. We present the main design principles and illustrate the advantages of...
