Prior sequence stratigraphic methods mainly employed two-dimensional (2-D) stacking patterns to reconstruct stratigraphic frameworks. The future of sequence stratigraphy will pay more attention to systems-tracts scale and three-dimensional (3-D) stratigraphic variability. Using 12 x 10(4) km(2) (4.63 x 10(3) mi(2)) 3-D seismic data, tied to regional 2-D seismic lines and 21 boreholes, the present study examines systems-tract scale and 3-D stratigraphic variability of the 14.8-13.8 Ma Pearl River shelf-margin to deep-water sedimentary prisms. The studied prisms were divided into four main systems tracts, namely, highstand systems tract (HST), falling-stage systems tract (FSST), lowstand systems tract (LST), and transgressive systems tract (TST). Each systems tract is represented by a given clinoformal architecture and stacking pattern: (1) clinothem sets with aggradation to progradation are HST, (2) clinothem sets with progradation to degradation (PD) are FSST, (3) clinothem sets with progradation to aggradation (PA) are LST, and (4) clinothem sets with retrogradation are TST, LST, or HST. In addition, Pearl River FSST and LST display downdip stratigraphic variabilities which are regionally manifested in at least three ways: (1) shelf-edge deltas linked downdip to basin-floor fans, (2) shelf-edge deltas linked downdip without fans, and (3) basin-floor fans linked updip that lack deltas. In along-strike orientation, the Pearl River FSST could exhibit low-angle progradation, not just PD stacking. The LST could present retrogradational stacking, not just PA stacking. Therefore, the physical position of a systems tract is reemphasized in terms of assigning a given systems tract. The concepts of three systems tracts are then revised for chronostratigraphic significance. The LST is the lowermost systems tract of a sequence, presenting a normal regression of the shoreline as its diagnostic characteristic and including contemporaneous stratigraphic units laterally. The HST is the upper systems tract of a sequence, providing a normal regression of the shoreline as its diagnostic characteristic and including contemporaneous stratigraphic units laterally. The TST is the middle systems tract of a sequence, generating a backstep of the shoreline and excluding contemporaneous onlapping units of both the LST and HST laterally. The FSST has not been revised because FSST may be a supply-independent feature.

Diet is an environmental factor with significant potential to affect the brain and behavior in both positive and negative ways. Work in animals is necessary to understand this relationship and how it may apply to mental health in humans. One area which has been investigated extensively is whether diet, specifically a high fat diet (HFD), can alter behavior in tasks, such as the forced swim test (FST) that assess stress coping. Therefore, we sought to analyze the literature regarding the effect of HFD on performance in the FST to determine whether there was a consistent effect of HFD on stress coping behavior. We conducted a Google Scholar search of English-language articles with the following terms: high fat diet, obesity, forced swim test, depression like behavior, mouse. Thirty studies from twenty-five publications are included in this survey. Fifteen studies were found where HFD had no effect on FST, 4 where HFD decreased immobility, and 11 where HFD increased immobility. Experimental details in these studies varied widely, including differences in the diet, mice, and experimental design. Additionally, we analyzed thirteen studies that performed the tail-suspension test (TST) after HFD, with six studies finding no change due to HFD and 7 reporting that HFD increased immobility. Further, 6 of these studies used both FST and TST with largely similar results in the two tasks, indicating concordance between the two tests of stress-coping behavior. We conclude that due to widely varying experimental details across studies no consistent effect of high fat diet on stress coping behavior can be determined at this point.
