Polyurethane foam has been the material of choice because of its good performance, ability to maintain properties across a wide range of temperature conditions, reasonable cost, and

Staffs of the Semiconductor Electronics Division, the Information Technology Laboratory, and the ... more Staffs of the Semiconductor Electronics Division, the Information Technology Laboratory, and the Precision Engineering Laboratory at NIST, have developed a new generation of prototype Single-Crystal CD (Critical Dimension) Reference (SCCDRM) Materials with the designation RM 8111. Their intended use is calibrating metrology instruments that are used in semiconductor manufacturing. Each reference material is configured as a 10 mm × 11 mm silicon test-structure chip that is mounted in a 200 mm silicon carrier wafer. The fabrication of both the chip and the carrier wafer uses the type of lattice-plane-selective etching that is commonly employed in the fabrication of micro electro-mechanical systems devices. The certified CDs of the reference features are determined from Atomic Force Microscope (AFM) measurements that are referenced to high-resolution transmission-electron microscopy images that reveal the cross-section counts of lattice planes having a pitch whose value is traceable to...

The purpose of this review is to explore recent advances in skull base surgery that are applicable to the orbital surgeon. Transnasal endoscopic surgery provides access to the medial 180 degrees of the orbit. Access to the lateral 180 degrees may be obtained using transmaxillary and transcranial techniques. Transorbital approaches and multiport techniques further expand the reach of the skull base surgeon. These minimally invasive techniques are supplanting the classical pterional, frontotemporal, frontotemporal orbitozygomatic, frontal, and subfrontal approaches. The role of the orbital surgeon in skull base surgery is changing. Transnasal and transcranial approaches to orbital disorders using minimally invasive techniques are becoming more common. In addition, transorbital access to the skull base, par...

Recent studies have highlighted inflammation in punctoplasty specimens in patients with punctal stenosis. Conjunctival biopsy has been suggested as a means to determine underlying aetiologies, although little is known regarding what conjunctival pathologies are associated with punctal stenosis. Our objective is to examine the pathological and immunological findings in conjunctival biopsy specimens in patients with presumed idiopathic punctal stenosis. A retrospective chart review was performed at a single institution over a 5 year period of patients with presumed idiopathic punctal stenosis who underwent conjunctival biopsy for histopathological and/or direct immunofluorescence (DIF) examination. Patients with known aetiologies of punctal stenosis were excluded. 23 patients met inclusion criteria. Conjunctival biopsies (n=36) from all 23 patients underwent histological examination. 35 specimens (97.2%) showed lym...

We focused upon estimating the magnitude of the binding cost for each age group across encoding time (Experiment 1; 900/1500 ms), presentation format (Experiment 2; simultaneous/sequential), and interference (Experiment 3; control/suffix) conditions. In Experiment 1, encoding time did not differentially influence binding in the two age groups. In Experiment 2, younger adults exhibited poorer binding performance with sequential relative to simultaneous presentation, and serial position analyses highlighted a particular age-related difficulty remembering the middle item of a series (for all memory conditions). Experiments 1-3 demonstrated small to medium binding effect sizes in older adults across all encoding conditions, with binding less accurate than shape memory. However, younger adults also displayed negative effects of binding (small to l...

Whether these principles could be adhered to and what impact on transplant outcome they might have is unknown. We evaluated the logistic challenges and outcomes of the first 100 kidney transplants performed in the Australian kidney paired donation program. Within 4 years, 17 donor surgeons at 12 centres were involved in 37 chain exchange surgeries. Sixteen kidneys were transplanted at the same hospital and 84 required transport to the recipient hospital. Mean (±SD) within chain anaesthetic induction time variability was 8 ± 18 min and mean individual surgeon operating time was 115 ± 44 min. In two cases, delays during donor surgery resulted in increased CIT by 1 h because of deferred transport. CIT was 2.6 ± 0.6 h for non-shipped and 6.8 ± 2.8 h for shipped kidneys, four kidn...

Arabic-speaking participants were purposively recruited to participate in 6 focus groups. Transcripts were analysed thematically. 53 participants, aged 19-77 years, and originating from 8 countries, participated in 1 of 6 focus groups. Participants identified as Christian (73%), Islam (26%), Buddhist (2%) or did not identify with any religion (2%). 6 themes (with subthemes) were identified; religious conviction; invisibility of organ donation; medical suspicion; owning the decision; and reciprocal benefit. Although organ donation is considered a generous life-saving 'gift', representative members of the Arabic-speaking community in Australia were unfamiliar with, unnerved by and sceptical about the donation process. Making positive decisions about organ donation would likely require resolving tensions between respecting family, community and religious values versus their individual auto...

Across 2 groups, participants were either asked whether they have experienced a tip-of-the-tongue (TOT) state or to make a feeling-of-knowing (FOK) judgment. We examined the overall reporting rate as well as subjective (not accompanied by partial information recall) TOT and FOK reporting, comparing whether these differed between emotional (negatively valenced and arousing) and neutral items. The results demonstrated that emotion does not impact semantic TOT and FOK reports, a conclusion supported by Bayesian analysis of the results. The outcomes extend other findings in the metamemory literature, and are discussed with a focus on future research avenues concerning interactions between emotion and metamemory.

Using a novel fluency paradigm, the present research examined whether or not the reverse is also true, that is, does memory retrieval influence the description of the conceptual self? Specifically, this study examined the effect of prior autobiographical reverie on the subsequent retrieval of stored self-concepts. Participants wrote a description of a personally relevant memory or a control topic (of no relevance to the self), following which they had 60 seconds to generate as many self-defining statements as possible, each beginning with I am. Participants engaging in autobiographical retrieval generated significantly more statements than those in the control condition, suggesting that autobiographical retrieval increased access to self-concepts. Type of statement also varied according to group. Participants in the autobiographical memory conditio...
