Most of the author's recent work has centered on the perception of environments and the human body's navigation through those environments, which has necessitated the construction of large-scale installations. So far, all but one of these installations have used sound as an integral component. The author believes that we, as both biological and cultural beings, live within three interlocking environments—the natural, the built and the media. This third is the newest, but certainly no less real than the other two.

AbstractThis article traces ‘difficult guests’ who violate the tacit rules that guide interactions between talk show hosts and their guests, between news anchors and their interviewees. The goal is to theorize the appearance of such guests on television against the background of four case studies. Using the media events and media scandals concepts as well as more recent work on ‘mediatization’, a new category of remarkable media occurrences is developed. Such ‘media incidents’ capture the resistance to media routines as well as the incorporation of resistance into those very routines. I will illustrate how media incidents make visible, for large audiences, the media’s daily habitual construction of reality. Despite their complex, even ambivalent nature, it is argued that media incidents perform a more critical function for citizens in media-saturated societies than both media events and scandals.

Deep learning is an undeniably hot topic, not only within both academia and industry, but also among society and the media. The reasons for the advent of its popularity are manifold: unprecedented availability of data and computing power, some innovative methodologies, minor but significant technical tricks, etc. However, interestingly, the current success and practice of deep learning seems to be uncorrelated with its theoretical, more formal understanding. And with that, deep learning’s state-of-the-art presents a number of unintuitive properties or situations. In this note, I highlight some of these unintuitive properties, trying to show relevant recent work, and expose the need to get insight into them, either by formal or more empirical means.

The radionuclide 54MnCl2 was used to examine the cellular manganese content of submerged cultures of Penicillium urticae NRRL 2159A. Liquid-scintillation spectroscopy allowed sensitive detection of isotopic manganese in both normally supplemented and manganese-deficient cultures. The cellular manganese content in supplemented cultures showed three distinct phases, including a period of uptake that coincided with the time of transition to antibiotic biosynthesis. Such an uptake was not seen for manganese-deficient cultures, but addition of normal quantities of unlabelled manganese to the media appeared to stimulate uptake. Preliminary characterization shows this manganese uptake is not inhibited by other metal ions, does not require metabolic energy or a protein component, but is disrupted by changes in incubation temperature. The significance of these observations is discussed in the light of recent work on the requirement for manganese for antibiotic biosynthesis in this organism.

Abstract Recent work by emotion researchers indicates that emotions have a multilevel structure. Sophisticated sentimentalists should take note of this work – for it better enables them to defend a substantive role for emotion in moral cognition. Contra May's rationalist criticisms, emotions are not only able to carry morally relevant information, but can also substantially influence moral judgment and reasoning.

SummaryThe sun as a magnetic star is described on the basis of recent work on solar magnetism. Observations at an arbitrary angle to the rotation axis would show a 22-year polar field variation and a 25-day equatorial sector variation. The sector variation would be similar to an oblique rotator with an angle of 90° between the magnetic and rotational axis.

Synthetic Work

Hydroxyapatite bioceramics has attracted many material scientists as it is the main constituent of the bone and the teeth in human body. The synthesis of the bioceramics has been performed for years. Nowadays, the synthetic work is not only focused on the hydroapatite but also on the fluorapatite and chlorapatite bioceramics since later materials have also biological compatibility with human tissues; and they may also be very promising for clinic purpose. However, in comparison of the synthetic bioceramics with natural one on microstructure, a great differences were observed according to our previous results. We have investigated these differences further in this work since they are very important to appraise the synthetic bioceramics for their clinic application.The synthetic hydroxyapatite and chlorapatite were prepared according to A. Krajewski and A. Ravaglioli and their recent work. The briquettes from different hydroxyapatite or chlorapatite powders were fired in a laboratory furnace at the temperature of 900-1300°C. The samples of human enamel selected for the comparison with synthetic bioceramics were from Chinese adult teeth.

Advancements in state of the art high density Head/Disk retrieval systems has increased the demand for sophisticated failure analysis methods. From 1968 to 1974 the emphasis was on the number of tracks per inch. (TPI) ranging from 100 to 400 as summarized in Table 1. This emphasis shifted with the increase in densities to include the number of bits per inch (BPI). A bit is formed by magnetizing the Fe203 particles of the media in one direction and allowing magnetic heads to recognize specific data patterns. From 1977 to 1986 the tracks per inch increased from 470 to 1400 corresponding to an increase from 6300 to 10,800 bits per inch respectively. Due to the reduction in the bit and track sizes, build and operating environments of systems have become critical factors in media reliability.Using the Ferrofluid pattern developing technique, the scanning electron microscope can be a valuable diagnostic tool in the examination of failure sites on disks.

Necrosis Factor

Tumour necrosis factor α (TNFα)-converting enzyme (TACE/ADAM-17, where ADAM stands for a disintegrin and metalloproteinase) releases from the cell surface the extracellular domains of TNF and several other proteins. Previous studies have found that, while purified TACE preferentially cleaves peptides representing the processing sites in TNF and transforming growth factor α, the cellular enzyme nonetheless also sheds proteins with divergent cleavage sites very efficiently. More recent work, identifying the cleavage site in the p75 TNF receptor, quantifying the susceptibility of additional peptides to cleavage by TACE and identifying additional protein substrates, underlines the complexity of TACE-substrate interactions. In addition to substrate specificity, the mechanism underlying the increased rate of shedding caused by agents that activate cells remains poorly understood. Recent work in this area, utilizing a peptide substrate as a probe for cellular TACE activity, indicates that the intrinsic activity of the enzyme is somehow increased.
