Feb 1, 2021 · In recent years, there has been a resurgence in methods that use distributed (neural) representations to represent and reason about semantic knowledge for robotics applications. However, while robots often observe previously unknown concepts, these representations typically assume that all concepts are known a priori, and incorporating new information requires all concepts to be learned afresh. Our work relaxes this limiting assumption of existing representations and tackles the incremental ...
Dec 4, 2008 · Adaptation of Mycoplasma gallisepticum to unfavorable growth conditions results in altered morphological and physiological characteristics of the cells. M. gallisepticum populations in a complete nutrient medium contain pear-shaped vegetative cells ( d ∼ 0.3 μm; l ∼ 0.8 μm) with pronounced polar and cytoskeletonlike structures. Such mycoplasma cells are able to induce damage in a bacterial genome, causing an SOS response of the test strain (Escherichia coli PQ37). In a starvation ...

X-ray absorption spectroscopy at the Ni, Mn, and Co K-edges is used to investigate the charge compensation mechanism and its relationship to the magnetic moments in Li1−xNi1/3Mn1/3Co1/3O2. Multiple analytical methods are compared to separate element-specific redox trends from collective effects. EXAFS is use
Various 5-substituted 2-(2-tosylaminophenyl)benzoxazoles were synthesized. The presence of intramolecular hydrogen bonding, the strength of which depends on the nature of the substituent, was shown by means of the IR spectra of the investigated series of compounds. A correlation between v NH and the Taft substituent constants was found. The investigated benzoxazoles have fluorescence in the yellow-green region of the spectrum; an anomalously large Stokes shift is characteristic for them. The ...
Oct 2, 2000 · PD-1 is an immunoinhibitory receptor expressed by activated T cells, B cells, and myeloid cells. Mice deficient in PD-1 exhibit a breakdown of peripheral tolerance and demonstrate multiple autoimmune features. We report here that the ligand of PD-1 (PD-L1) is a member of the B7 gene family. Engageme …
