BACKGROUND Brainstem auditory evoked response has been an underused diagnostic modality in horses as evidenced by few reports on the subject. HYPOTHESIS/OBJECTIVES To describe BAER findings, common clinical signs, and causes of hearing loss in adult horses. ANIMALS Study group, 76 horses; control group, 8 horses. METHODS Retrospective. BAER records from the Clinical Neurophysiology Labora...

Bacterial two-component regulatory systems (TCSs) facilitate changes in gene expression in response to environmental stimuli. TCS BaeR regulons influence tigecycline susceptibility in Acinetobacter baumannii through positively regulating the pump genes adeA and adeB. In this study, we demonstrate that an additional two transport systems, AdeIJK and MacAB-TolC, are also regulated by BaeSR. In th...

In two recent papers [9, 10] we answered a question raised in the book by Eklof and Mekler [7, p. 455, Problem 12] under the set theoretical hypothesis of ♦א1 which holds in many models of set theory, respectively of the special continuum hypothesis (CH). The objects are reflexive modules over countable principal ideal domains R, which are not fields. Following H. Bass [1] an R-module G is refl...

Brainstem auditory evoked response (BAER) was studied in term neonates using maximum length sequences (MLS), which allows presentation of acoustic stimuli at much higher rate than possible with conventional averaging technique. The response waveforms, especially for waves III and V, were well defined at the click rates of 91-455/s. Wave latencies and interpeak intervals at various click rates w...

First we define relations between the v = (s2+s+1}(s+l) flags (point-line incident pairs) of a finite projective plane of order s. Two flags a =(p,i) and b =(p' ,l'), where p and p' are two points and l and l' are two lines of the projective plane, are defined to be first associates if either p = p' or l = l'; second associates if p # p', l # l' but either p is incident also with l' or p' is in...

Assuming the continuum hypothesis, we construct a pure subgroup G of the Baer–Specker group Zא0 with the following properties. Every endomorphism of G differs from a scalar multiplication by an endomorphism of finite rank. Yet G has uncountably many homomorphisms to Z.

Lattice theory originated late in the last century along two strands. Many of the structures used in logic have lattices, particularly distributive lattices, associated with them. The work of Boole [4] and Schröder [27] are seminal in this regard. The other strand, which concentrated more on the connections with algebra, was initiated with Richard Dedekind [6] in his studies of ideals in algebr...
