Architected metallic materials generally suffer from a serious engineering problem of mechanical instability manifested as the emergence localized deformation bands and collapse strength. They usually cannot exhibit satisfactory shape recoverability due to little recoverable strain constituent material. After yielding, material exhibits continuous low strain-hardening capacity, giving local yie...

Shortly after the death of Albert von Schrenck-Notzing (1862-1929), the doyen of early twentieth century German para psychology, his former colleague in hypnotism and sexology Albert Moll (1862-1939) published a treatise on the psychology and pathology of parapsychologists, with Schrenck-Notzing serving as a prototype of a scientist suffering from an 'occult complex'. Moll's analysis concluded ...

Female mating preferences can be secondarily lost for a number of reasons. We examined the preference of female pygmy swordtails, Xiphophorus nigrensis, for the sword, a conspicuous extension of the caudal fin in some males. Females failed to show a preference for conspecific males with swords when presented with live males naturally varying in sword length, with live males of manipulated sword...

Supernormal conduction (SNC) in excitable cardiac tissue refers to an increase of pulse (or action potential) velocity with decreasing distance to the preceding pulse. Here we employ a simple ionic model to study the effect of SNC on the propagation of action potentials (APs) and the phenomenology of alternans in excitable cardiac tissue. We use bifurcation analysis and simulations to study att...

A B S T R A C T During the course of Plasmodium berghei malaria in the rat, splenic clearance ofdamaged uninfected erythrocytes (heated or Heinz body-containing) underwent changes strikingly similar to those of infected erythrocytes. Splenic trapping of abnormal erythrocytes was impaired during the period of rising parasitemia but became supernormal just before the onset of resolution ofthe acu...

We have investigated the utility of bone marrow-derived mesenchymal stem cells (MSCs) as targets for gene therapy of the autosomal recessive disorder mucopolysaccharidosis type IH (MPS-IH, Hurler syndrome). Cultures of MSCs were initially exposed to a green fluorescent protein-expressing retrovirus. Green fluorescent protein-positive cells maintained their proliferative and differentiation capa...

A number of prioritized variants of Reiter’s default logic have been described in the literature. In this paper, we introduce two natural principles for preference handling and show that all existing approaches fail to satisfy them. We develop a new approach which does not suffer from these shortcomings. We start with the simplest case, supernormal default theories, where preferences are handle...

Seventeen patient with sinoatrial block and 16 healthy volunteers were investigated with recently developed autonomic tests of atrial pacemaker function. Only one patients was found to be entirely normal in comparison with normal subjects, while another patients had supernormal responses. Fifteen patients had reduced responses relative to the controls implying impaired atrial pacemaker function...
