Lepidozona abyssicola A. G. Smith & Cowan 1966
Lepidozona abyssicola (A. G. Smith & Cowan, 1966) Ischnochiton abyssicola A. G. Smith & Cowan 1966: 4, figs 1–19. Of the 13 specimens mentioned in the original description, only one paratype was collected at an abyssal depth. This specimen was collected off the coast of Oregon, USA (44 ° 33.5 'N, 125 ° 14.6 'W), at 2000 m. Subsequently, Clark (2000) reported this species from near the Farallon Islands [37 ° 44 ’N, 123 °03’W], California, 2750 m. Genus Stenosemus von Middendorff, 1847 Type species: Chiton albus Linnaeus, 1767, subsequently designated by Winckworth (1926).Published as part of Schwabe, Enrico, 2008, A summary of reports of abyssal and hadal Monoplacophora and Polyplacophora (Mollusca) *, pp. 205-222 in Zootaxa 1866 on page 216, DOI: 10.5281/zenodo.18381
Attention to attributes and objects in working memory
It has been debated on the basis of change-detection procedures whether visual working memory is limited by the number of objects, task-relevant attributes within those objects, or bindings between attributes. This debate, however, has been hampered by several limitations, including the use of conditions that vary between studies and the absence of appropriate mathematical models to estimate the number of items in working memory in different stimulus conditions. We reexamined working memory limits in 2 experiments with a wide array of conditions involving color and shape attributes, relying on a set of new models to fit various stimulus situations. In Experiment 2, a new procedure allowed identical retrieval conditions across different conditions of attention at encoding. The results show that multiple attributes compete for attention, but that retaining the binding between attributes is accomplished only by retaining the attributes themselves. We propose a theoretical account in which a fixed object capacity limit contains within it the possibility of the incomplete retention of object attributes, depending on the direction of attention.</p
Models of verbal working memory capacity: What does it take to make them work?
Theories of working memory (WM) capacity limits will be more useful when we know what aspects of performance are governed by the limits and what aspects are governed by other memory mechanisms. Whereas considerable progress has been made on models of WM capacity limits for visual arrays of separate objects, less progress has been made in understanding verbal materials, especially when words are mentally combined to form multiword units or chunks. Toward a more comprehensive theory of capacity limits, we examined models of forced-choice recognition of words within printed lists, using materials designed to produce multiword chunks in memory (e.g., leather brief case). Several simple models were tested against data from a variety of list lengths and potential chunk sizes, with test conditions that only imperfectly elicited the interword associations. According to the most successful model, participants retained about 3 chunks on average in a capacity-limited region of WM, with some chunks being only subsets of the presented associative information (e.g., leather brief case retained with leather as one chunk and brief case as another). The addition to the model of an activated long-term memory component unlimited in capacity was needed. A fixed-capacity limit appears critical to account for immediate verbal recognition and other forms of WM. We advance a model-based approach that allows capacity to be assessed despite other important processing contributions. Starting with a psychological-process model of WM capacity developed to understand visual arrays, we arrive at a more unified and complete model.</p
, cowan I
Staphylococcus aureus, strain Cowan I, contains a cell‐wall substance, protein A, which combines with the Fc part of IgG in most mammalian species. It can therefore be used as a solid‐phase immunoabsorbant for elimination of the reacting immunoglobulins. Since it has been shown that Cowan I could absorb out the blocking activity of sera from rats bearing isografts of polyoma‐virus‐induced sarcomas or chemically induced colon carcinomas, we investigated what effects Cowan I absorption of human tumor‐bearer sera might have. In all tumor‐bearer sera tested, from patients with melanomas or colon carcinomas, treatment with protein‐A‐containing staphylococci decreased the sera's ability to inhibit lymphocyte‐mediated cytotoxicity in vitro. Cowan‐I‐treated sera from healthy controls had no effect on lymphocyte cytotoxicity. Nor did Cowan‐I‐treated tumor‐bearer sera potentiate or „arm” normal lymphocytes against tumor target cells. There was no evidence of complement‐dependent cytotoxicity with added human complement in sera from melanoma and colon carcinoma bearing patients either before or after absorption with Staphylococcus aureus, Cowan I. The concentrations of IgA, IgG and IgM were determined in sera used for in vitro tests of blocking activity and complement‐dependent cytotoxicity before and after absorption. No reduction of IgA, reduction to undetectable levels of IgG and 20–30% reduction of IgM immunoglobulins as compared to unabsorbed sera were demonstrated

One black and white photographic print of Lester Cowan, a 1925 graduate of The Municipal University of Akron (now The University of Akron) in Akron, Ohio, who later went on to serve as Executive Secretary of The Academy of Motion Picture Arts and Sciences in Hollywood, California. Cowan produced over ten motion pictures, including ""Story of G. I. Joe"" and ""Tomorrow, The World!"" The photograph is lightly soiled, especially on the back. It is stamped on the back ""Academy of Motion Picture Arts and Sciences, Suite 210, 7046 Hollywood Boulevard, Hollywood, California."

G-quadruplexes mediate local translation in neurons
There has recently been a huge increase in interest in the formation of stable G-quadruplex structures in mRNAs and their functional significance. In neurons, local translation of mRNA is essential for normal neuronal behaviour. It has been discovered that local translation of specific mRNAs encoding some of the best known synaptic proteins is dependent on the presence of a G-quadruplex. The recognition of G-quadruplexes in mRNAs, their transport as repressed complexes and the control of their translation at their subcellular destinations involves a diversity of proteins, including those associated with disease pathologies. This is an exciting field, with rapid improvements to our knowledge and understanding. Here, we discuss some of the recent work on how G-quadruplexes mediate local translation in neurons
