Using content analysis to characterise the sensory typicity and quality judgements of Australian Cabernet Sauvignon wines
Understanding the sensory attributes that explain the typicity of Australian Cabernet Sauvignon wines is essential for increasing value and growth of Australia's reputation as a fine wine producer. Content analysis of 2598 web-based wine reviews from well-known wine writers, including tasting notes and scores, was used to gather information about the regional profiles of Australian Cabernet Sauvignon wines and to create selection criteria for further wine studies. In addition, a wine expert panel evaluated 84 commercial Cabernet Sauvignon wines from Coonawarra, Margaret River, Yarra Valley and Bordeaux, using freely chosen descriptions and overall quality scores. Using content analysis software, a sensory lexicon of descriptor categories was built and frequencies of each category for each region were computed. Distinction between the sensory profiles of the regions was achieved by correspondence analysis (CA) using online review and expert panellist data. Wine quality scores obtained from reviews and experts were converted into Australian wine show medal categories. CA of assigned medal and descriptor frequencies revealed the sensory attributes that appeared to drive medal-winning wines. Multiple factor analysis of frequencies from the reviews and expert panellists indicated agreement about descriptors that were associated with wines of low and high quality, with greater alignment at the lower end of the wine quality assessment scale.Lira Souza Gonzaga, Dimitra L.

Mapping cell-in-cell structures in oral squamous cell carcinoma
Cell-in-cell (CIC) structures contribute to tumor aggressiveness and poor prognosis in
oral squamous cell carcinoma (OSCC). In vitro 3D models may contribute to the understanding of
the underlying molecular mechanisms of these events. We employed a spheroid model to study
the CIC structures in OSCC. Spheroids were obtained from OSCC (HSC3) and cancer-associated
fibroblast (CAF) lines using the Nanoshuttle-PLTM bioprinting system (Greiner Bio-One). Spheroid
form, size, and reproducibility were evaluated over time (EvosTM XL; ImageJ version 1.8). Slides
were assembled, stained (hematoxylin and eosin), and scanned (Axio Imager Z2/VSLIDE) using
the OlyVIA System (Olympus Life Science) and ImageJ software (NIH) for cellular morphology and
tumor zone formation (hypoxia and/or proliferative zones) analysis. CIC occurrence, complexity, and
morphology were assessed considering the spheroid regions. Well-formed spheroids were observed
within 6 h of incubation, showing the morphological aspects of the tumor microenvironment, such
as hypoxic (core) and proliferative zone (periphery) formation. CIC structures were found in both
homotypic and heterotypic groups, predominantly in the proliferative zone of the mixed HSC3/CAF
spheroids. âComplex cannibalismâ events were also noted. These results showcase the potential of
this model in further studies on CIC morphology, formation, and relationship with tumor prognosis
Pan American interactions of Amazon precipitation, streamflow, and tree growth extremes
Rainfall and river levels in the Amazon are associated with significant precipitation anomalies of opposite sign in temperate North and South America, which is the dominant mode of precipitation variability in the Americas that often arises during extremes of the El Niño/Southern Oscillation (ENSO). This co-variability of precipitation extremes across the Americas is imprinted on tree growth and is detected when new tree-ring chronologies from the eastern equatorial Amazon are compared with hundreds of moisture-sensitive tree-ring chronologies in mid-latitude North and South America from 1759 to 2016. Pan-American co-variability exists even though the seasonality of precipitation and tree growth only partially overlaps between the Amazon and mid-latitudes because ENSO forcing of climate can persist for multiple seasons and can orchestrate a coherent response, even where the growing seasons are not fully synchronized. The tree-ring data indicate that the El Niño influence on inter-hemispheric precipitation and tree growth extremes has been strong and stable over the past 258-years, but the La Niña influence has been subject to large multi-decadal changes. These changes have implications for the dynamics and forecasting of hydroclimatic variability over the Americas and are supported by analyses of the available instrumental data and selected climate model simulations.Fil: Stahle, D.W..

A statistical interpretation of the correlation between intermediate mass fragment multiplicity and transverse energy
Multifragment emission following Xe+Au collisions at 30, 40, 50 and 60 AMeV
has been studied with multidetector systems covering nearly 4-pi in solid
angle. The correlations of both the intermediate mass fragment and light
charged particle multiplicities with the transverse energy are explored. A
comparison is made with results from a similar system, Xe+Bi at 28 AMeV. The
experimental trends are compared to statistical model predictions.Comment: 7 pages, submitted to Phys. Rev.
