Previous studies of the auditory P300 event-related potential (ERP) from our laboratory have reported a left- greater than right-sided attenuation in medicated chronic schizophrenics compared with normal controls. A possible confound in these studies has been the use of the linked-ear reference (LER), which has been criticized on the grounds that it might either induce or suppress topographic a...
OBJECTIVE To describe the differences in socio-economic characteristics and body measurements between low, adequate and high energy reporting (LER, AER and HER) teenagers; furthermore, to investigate the relationship to misreporting mothers. DESIGN Cross-sectional study. Habitual dietary intake was reported in a questionnaire. Classification into LER, AER and HER using the Goldberg equation w...
Line Edge Roughness (LER), caused by tolerances inherent to materials and tools used in lithography processes, is not a new phenomenon. Yet, the imperfections caused by LER have caused little worry over the years since the critical dimensions of MOSFETs were almost two orders of magnitude larger than the roughness. However, as the aggressive scaling of Si-MOSFETs continues to the sub-100 nm reg...
In this paper we investigated the line edge roughness (LER) effects on the 22-nm and 14nm inversion mode (IM) and jounctionless (JL) FinFETs by TCAD simulation. We examined the gate LER (GLER) effects and the fin LER (FLER) effects on the device variability separately. The simulation results show that the GLER-induced device variations will increase as the channel length decrease as expectation...
Transcription of the locus of enterocyte effacement (LEE) genes in enterohemorrhagic Escherichia coli (EHEC) is regulated by the LEE-encoded Ler and GrlR/GrlA proteins as well as the non-LEE-encoded regulator QseA. This work demonstrates that GrlR/GrlA activate LEE2 transcription in a Ler-independent fashion, whereas transcription of grlRA is activated by QseA in both Ler-dependent and -indepen...
Leaf elongation rate (LER) in grasses is dependent on epidermal cell supply (number) and on rate and duration of epidermal cell elongation. Nitrogen (N) fertilization increases LER. Longitudinal sections from two genotypes of tall fescue (Festuca arundinacea Schreb.), which differ by 50% in LER, were used to quantify the effects of N on the components of epidermal cell elongation and on mesophy...
As critical dimensions shrink, line edge and width roughness (LER and LWR) become of increasing concern. Traditionally LER is viewed as a resist-limited effect; however, as critical dimensions shrink and LER requirements become proportionally more stringent, system-level effects begin to play an important role. Recent advanced EUV resist testing results have demonstrated lower bounds on achieva...
The formation of attaching and effacing (A/E) lesions on intestinal epithelial cells is an essential step in the pathogenesis of human enteropathogenic and enterohemorrhagic Escherichia coli and of the mouse pathogen Citrobacter rodentium. The genes required for the development of the A/E phenotype are located within a pathogenicity island known as the locus of enterocyte effacement (LEE). The ...
We describe the present status of the PEP-II project. The project comprises four major systems: Injector, High-Energy Ring (HER), Low-Energy Ring (LER), and Interaction Region (IR). We focus in detail on the design of the LER, as its parameters and requirements are most closely related to those required for the Beijing Tau-Charm Factory rings. The PEP-II LER is a high-current, 3.1-GeV positron ...
Enteropathogenic Escherichia coli (EPEC) causes severe diarrhea in young children. Essential for colonization of the host intestine is the LEE pathogenicity island, which comprises a cluster of operons encoding a type III secretion system and related proteins. The LEE1 operon encodes Ler, which positively regulates many EPEC virulence genes in the LEE region and elsewhere in the chromosome. We ...
