It is known that the Axiom of Infinity can be stated, relative to the standard ZermeloFraenkel-von Neumann set theory ZF, as an assertion of very low structural complexity: namely, one which involves only universal restricted quantifiers, i.e., belongs to the Bernays-Schönfinkel-Ramsey class BSR. We will exhibit, in Part I, two similar assertions of existence of infinite sets [POT09]: both belo...
from CRF to the schedule (12). Accordingly, it is not BSR per se that makes schedule control difficult, but its property of being applied in the last link of a one-link chain. Other applied reinforcers pose similar problems in rats and ducklings (13) as well as humans (14). Carlisle (15) found that rats pressing to turn on a heat lamp reinforcer in a cold chamber performed well on a CRF schedul...
We present a new technology for super-resolution fluorescence imaging, based on conical diffraction. Conical diffraction is a linear, singular phenomenon, taking place when a laser beam is diffracted through a biaxial crystal. We use conical diffraction in a thin biaxial crystal to generate illumination patterns that are more compact than the classical Gaussian beam, and use them to generate a ...
Crops carrying broad-spectrum resistance loci provide an effective strategy for controlling infectious disease because these loci typically confer resistance to diverse races of a pathogen or even multiple species of pathogens. Despite their importance, only a few crop broad-spectrum resistance loci have been reported. Here, we report the identification and characterization of the rice bsr-k1 (...
Facioscapulohumeral dystrophy (FSHD) is an epi/genetic satellite disease associated with at least two satellite sequences in 4q35: (i) D4Z4 macrosatellite and (ii) β-satellite repeats (BSR), a prevalent part of the 4qA allele. Most of the recent FSHD studies have been focused on a DUX4 transcript inside D4Z4 and its tandem contraction in FSHD patients. However, the D4Z4-contraction alone is not...
Phialophora gregata (Allington & D. W. Chamberlain) W. Gams, the causal agent of brown stem rot (BSR) of soybean (Glycine max L.) (1), and Heterodera glycines Ichinohe, the soybean cyst nematode, are widely distributed throughout the midwestern United States (32). The current recommended management strategy for both pathogens is the use of resistant soybean cultivars combined with rotation to n...
time each day, in closed, sound-insulated chambers, with continuous white masking noise. There were thus no distractions to interfere with the performance of the task. Another feature that may have influenced the result is that the rat's first response in the session was usually reinforced. Contrast effect may have contributed to the widespread impression that BSR results in rapid extinction. A...
The imprinted Dlk1-Gtl2 and Prader-Willi syndrome (PWS) regions are characterized by a complex noncoding transcription unit spanning arrays of tandemly repeated C/D RNA genes. These noncoding RNAs (ncRNAs) are thought to play an essential but still poorly understood role. To better understand the intracellular fate of these large ncRNAs, fluorescence in situ hybridization was carried out at the...
OBJECTIVE Self-help agencies (SHAs) are consumer-operated service organizations managed as participatory democracies involving members in all management tasks. Hierarchically organized board- and staff-run consumer-operated service programs (BSR-COSPs) are consumer managed, but they afford members less decision-making power. This study considered the relative effectiveness of SHAs and BSR-COSPs...
587 Abstract: The severity of brown stem rot (BSR) on soybean (Glycine max) is influenced by environment, genotype of the pathogen, and genetic resistance to BSR. BSR is caused by two genotypes of Phialophora gregata: genotype A causes pith browning and leaf necrosis, and genotype B typically causes only pith browning. The distribution of the genotypes and their interactions with resistant and ...
