      • Considerations for the incorporation of measured surfaces in finite element models.

        Thompson, Mary Kathryn,Thompson, John M Gerhard Witzstrock Pub. House 2010 Scanning Vol.32 No.4

        <P>This work discusses some of the benefits, techniques, challenges, and considerations associated with the incorporation of measured surfaces in finite element (FE) models including how much surface data to measure and import into the model, the shape of the surface geometry to create, the presence and effect of surface layers and impurities, the required mesh density for rough surfaces, the nature of the element formulations and material properties at small length scales, the differences between measurement and FE coordinate systems, the limitations and idealizations of the FE method, issues associated with boundary conditions and their ability to impose or prevent conformal contact, and issues associated with the size of the pinball region and the contact stiffness relative to the nature of the surface. It also describes some current and future research directions that can be used to validate and expand existing techniques and to improve our understanding of surface phenomena.

        Information Asymmetry, Time until Deal Completion and Post-M&A Performance

        ( Ephraim Kwashie Thompson ),( Changki Kim ) 한국파생상품학회(구 한국선물학회) 2020 선물연구 Vol.28 No.3

        This paper aims to show that information asymmetry plays a vital role in the post-M&A performance-time until deal completion nexus. The findings are that the due diligence hypothesis and the overdue hypothesis proposed and tested in Thompson and Kim (2020) are influenced by the information asymmetry of the target during the negotiation process. Thus, mergers that involve more opaque targets that take a shorter time to close perform better, whereas those that take too long to close experience poor post-M&A performance. Conversely, there is no such effect when the mergers involve targets that are transparent and not plagued with large information asymmetry problems. These results hold for the short-term supporting the evidence that information asymmetry problems are severe before the merger is consummated and become attenuated post-merger.

        Gastrulation : Current Concepts and Implications for Spinal Malformations

        Thompson, Dominic Nolan Paul The Korean Neurosurgical Society 2021 Journal of Korean neurosurgical society Vol.64 No.3

        It has been recognised for over a century that the events of gastrulation are fundamental in determining, not only the development of the neuraxis but the organisation of the entire primitive embryo. Until recently our understanding of gastrulation was based on detailed histological analysis in animal models and relatively rare human tissue preparations from aborted fetuses. Such studies resulted in a model of gastrulation that neurosurgeons have subsequently used as a means of trying to explain some of the congenital anomalies of caudal spinal cord and vertebral development that present in paediatric neurosurgical practice. Recent advances in developmental biology, in particular cellular biology and molecular genetics have offered new insights into very early development. Understanding the processes that underlie cellular interactions, gene expression and activation/inhibition of signalling pathways has changed the way embryologists view gastrulation and this has led to a shift in emphasis from the 'descriptive and morphological' to the 'mechanistic and functional'. Unfortunately, thus far it has proved difficult to translate this improved knowledge of normal development, typically derived from non-human models, into an understanding of the mechanisms underlying human malformations such as the spinal dysraphisms and anomalies of caudal development. A paediatric neurosurgeons perspective of current concepts in gastrulation is presented along with a critical review of the current hypotheses of human malformations that have been attributed to disorders of this stage of embryogenesis.

        Lymph nodes as barriers to T‐cell rejuvenation in aging mice and nonhuman primates

        Thompson, Heather L.,Smithey, Megan J.,Uhrlaub, Jennifer L.,Jeftić,, Ilija,Jergović,, Mladen,White, Sarah E.,Currier, Noreen,Lang, Anna M.,Okoye, Afam,Park, Byung,Picker, Louis J.,Surh, Char BLACKWELL PUBLISHING 2019 Aging Cell Vol.18 No.1

        <P><B>Abstract</B></P><P>In youth, thymic involution curtails production of new naïve T cells, placing the onus of T‐cell maintenance upon secondary lymphoid organs (SLO). This peripheral maintenance preserves the size of the T‐cell pool for much of the lifespan, but wanes in the last third of life, leading to a dearth of naïve T cells in blood and SLO, and contributing to suboptimal immune defense. Both keratinocyte growth factor (KGF) and sex steroid ablation (SSA) have been shown to transiently increase the size and cellularity of the old thymus. It is less clear whether this increase can improve protection of old animals from infectious challenge. Here, we directly measured the extent to which thymic rejuvenation benefits the peripheral T‐cell compartment of old mice and nonhuman primates. Following treatment of old animals with either KGF or SSA, we observed robust rejuvenation of thymic size and cellularity, and, in a reporter mouse model, an increase in recent thymic emigrants (RTE) in the blood. However, few RTE were found in the spleen and even fewer in the lymph nodes, and SSA‐treated mice showed no improvement in immune defense against West Nile virus. In parallel, we found increased disorganization and fibrosis in old LN of both mice and nonhuman primates. These results suggest that SLO defects with aging can negate the effects of successful thymic rejuvenation in immune defense.</P>

      • Beef quality grades as determined by Korean and Australian consumers

        Thompson, J. M.,Polkinghorne, R.,Hwang, I. H.,Gee, A. M.,Cho, S. H.,Park, B. Y.,Lee, J. M. CSIRO Publishing 2008 Australian journal of experimental agriculture Vol.48 No.11

        <P> Consumer responses were examined in an incomplete factorial design where Australian consumers evaluated 216 beef samples derived from 18 cattle killed in Australia and Korean consumers evaluated 216 samples from the same 18 cattle, plus 216 similar samples from 18 Korean cattle. Samples of the Mm. triceps brachii, longissimus dorsi and semimembranosus were cooked using grill and Korean barbeque methods. Each sample was sensory tested by 10 consumers, who scored it for tenderness, juiciness, like flavour, and overall liking. Consumers then graded each sample as either unsatisfactory (2 star), good every day (3 star), better than every day (4 star), or premium (5 star) quality. For those samples assessed by both Australian and Korean consumers, the Korean consumers graded a higher proportion of samples ‘unsatisfactory’ and a lower proportion of samples ‘premium’ grade product than Australian consumers. Using a composite meat quality score (MQ4) to predict grade, a discriminant analysis showed that the Korean consumers had boundary cut-offs for the lower grades, which were ~4-10 palatability units higher than the Australian consumers. Analysis of the residuals between actual and predicted palatability scores showed that the Meat Standards Australia (MSA) grading model produced relatively unbiased estimates within ±2 MQ4 units for the different consumer groups, muscle and carcass suspension treatments, with the exception of the M. semimembranosus samples. Implications of the results for both Korean and Australian beef markets through the use of an empirical grading model to predict palatability are discussed. </P>
