The Eocene succession of the El Basatin Section in Gebel Mokattam, east of Cairo, consists, from base to top, of two main units; the Mokattam and Maadi Formations. The Mokattam Formation consists of two Members, the Building Stone Member and the Giushi Member. The Upper Building Stone Member yielded six species of Nummulites belonging to the Upper Lutetian. These species are: Nummulites farisi Hussein et al., 2004; Nummulites cf. praegizehensis Boukhary and Hussein-Kamel, 1993; Nummulites cf. gizehensis(Forsk?l, 1775); Nummulites discorbinus(Schlotheim 1820) and Arxina schwageri(Silvestri, 1928) emended by Boukhary et al. 2012 and Nummulites crassichordatus Boukhary et al., 2010. The Giushi Member yielded three species that indicate a Bartonian age. These species, which continued from their first appearance in the Upper Building Stone Members, are N. discorbinus, A. schwageri and N. crassichordatus. The Maadi Formation, which has been previously considered to be of Bartonian–Priabonian age, is devoid of fossils in the study section. The two members of the Mokattam Formation represent a carbonate platform facies. The deposition of the Upper Building Stone Member was disturbed during the Lutetian by slumping and a convolute-bedding interval, indicating a short Hiatus. The subsequent regression resulted in a very shallow marine to near-shore facies in the above Maadi Formation.

Temperature is a crucial factor that affects in flue nza tran smissi on. Therefore, several studies have correlated various aspects of in flue nza with temperature from the global warming period during which temperature exhibits a clear trend. The global warming Hiatus has been existing since the year 1998. This provides an opportunity to investigate the effect of temperature on the transmission of influenza from the viewpoint that temperature is trendless.

Global mean surface air temperature(SAT)has remained relative stagnant since the late 1990s,a phenomenon known as global warming Hiatus.Despite widespread concern and discussion,there is still an open question about whether this Hiatus exists,partly due to the biases in observations.The stable isotopic composition of precipitation in mid-and high-latitude continents closely tracks change of the air temperature,providing an alternative to evaluate global warming Hiatus.Here we use the long-term precipitation δ^18O records available to investigate changes in SAT over the period 1970–2016.The results reveal slight decline in δ^18O anomaly from 1998 to 2012,with a slope of?0.0004‰decade?1 which is significantly different from that of pre-1998 interval This downwardδ18O anomaly trend suggests a slight cooling for about?0.001℃ decade?1,corroborating the recent Hiatus in global warming.Our work provides new evidence for recent global warming Hiatus and highlights the potential of utilizing precipitation isotope for tracking climate changes.

The global warming slowdown or warming Hiatus, began around the year 2000 and has persisted for nearly 15 years. Most studies have focused on the interpretation of the Hiatus in temperature. In this study, changes in a global aridity index （AI） were analyzed by using a newly developed dynamical adjustment method that can successfully identify and separate dynamically induced and radiatively forced aridity changes in the raw data. The AI and Palmer Drought Severity Index produced a wetting zone over the mid-to-high latitudes of the Northern Hemisphere in recent decades. The dynamical adjustment analysis suggested that this wetting zone occurred in response to the global warming Hiatus. The dynamically induced AI （DAI） played a major role in the AI changes during the Hiatus period, and its relationships with the North Atlantic Oscillation （NAO）, Pacific Decadal Oscillation （PDO）, and Atlantic Multi-decadal Oscillation （AMO） also indicated that different phases of the NAO, PDO, and AMO contributed to dif- ferent performances of the DAI over the Northern Hemisphere. Although the aridity wetting over the mid-to-high lat- itudes may relieve long-term drying in certain regions, the Hiatus is temporary, and so is the relief. Accelerated glob- al warming will return when the NAO, PDO, and AMO revert to their opposite phases in the future, and the wetting zone is likely to disappear.

Observed Hiatus or accelerated warming phenomena are compared with numerical simulations from the Coupled Model Intercomparison Project Phase 5 （CMIP5） archives,and the associated physical mechanisms are explored based on the CMIP5 models.Decadal trends in total ocean heat content （OHC） are strongly constrained by net top-of-atmosphere （TOA） radiation.During Hiatus decades,most CMIP5 models exhibit a significant decrease in the SST and upper OHC and a significant increase of heat penetrating into the subsurface or deep ocean,opposite to the accelerated warming decades.The shallow meridional overturning of the Pacific subtropical cell experiences a significant strengthening （slowdown） for the Hiatus （accelerated warming） decades associated with the strengthened （weakened） trade winds over the tropical Pacific.Both surface heating and ocean dynamics contribute to the decadal changes in SST over the Indian Ocean,and the Indonesian Throughflow has a close relationship with the changes of subsurface temperature in the Indian Ocean.The Atlantic Meridional Overturing Circulation （Antarctic Bottom Water） tends to weaken （strengthen） during Hiatus decades,opposite to the accelerated warming decades.In short,the results highlight the important roles of air-sea interactions and ocean circulations for modulation of surface and subsurface temperature.

An abrupt temperature change and a warming Hiatus have strongly influenced the global climate.This study focused on these changes in Inner Mongolia, China. This study used the central clustering method, Mann-Kendall mutation test and other methods to explore the abrupt temperature change and warming Hiatus in three different temperature zones of the study region based on average annual data series.Among the temperature metrics investigated, average minimum temperature(Tnav) shifted the earliest,followed by average temperature(Tnv) and average maximum temperature(Txav). The latest change was observed in summer(1990 s), whereas the earliest was observed in winter(1970 s). Before and after the abrupt temperature change, Tnav fluctuated considerably, whereas there was only a slight change in Txav.Before and after the abrupt temperature change, the winter temperature changed more dramatically than the summer temperature. Before the abrupt temperature change, Tnav in the central region(0.322°C/10 a)and west region(0.48°C/10 a) contributed the most to the increasing temperatures. After the abrupt temperature change, Tnav in winter in the central region(0.519°C/10 a) and in autumn in the west region(0.729°C/10 a) contributed the most to the temperature increases. Overall, in the years in which temperature shifts occurred early, a warming Hiatus also appeared early. The three temperature metrics in spring(1991)in the east region were the first to exhibit a warming Hiatus. In the east region, Txav displayed the lowest rate of increase(0.412°C/a) in the period after the abrupt temperature change and before the warming Hiatus,and the highest rate of increase after the warming Hiatus.

The 1998-2012 global wanning Hiatus has aroused great public interest over the past several years.Based on the air temperature measurements from 622 meteorological stations in China,the temperature response to the global warming Hiatus was analyzed at national and regional scales.We found that air temperature changed-0.221°C/10a during 1998-2012,which was lower than the long-term trend for 1960-1998 by 0.427°C/10a.Therefore,the warming Hiatus in China was more pronounced than the global mean.Winter played a domi nant role in the nati on wide warming Hiatus,con tributi ng 74.13%,while summer contributed the least among the four seasons.Furthermore,the warming Hiatus was spatial heterogeneous across different climate conditions in China.Comparing the three geographic zones,the monsoon region of eastern China,arid region of northwestern China,and high frigid region of the Tibetan Plateau,there was significant cooling in eastern and northwestern China.In eastern China,which contributed 53.79%,the trend magnitudes were 0.896°C/10a in winter and 0.134°C/10a in summer.In the Tibeta n Plateau,air temperature in creased by 0.204°C/10a,indicating a lack of a significant warming Hiatus.More broadly,the warming Hiatus in China may have been associated with the negative phase of PDO and reduction in sunspot numbers and total solar radiation.Finally,although a warming Hiatus occurred in China from 1998 to 2012,air temperature rapidly increased after 2012 and will likely to continuously warm in the next few years.

"Warming Hiatus" occurred in the AltaySayan Mountain Region, Siberia in c. 1997–2014. We analyzed evergreen conifer(EGC) stands area(satellite data) and trees(Siberian pine, Pinus sibirica Du Tour, Siberian fir, Abies sibirica Ledeb.) growth increment(dendrochronology data) response to climate variables before and during the Hiatus. During the Hiatus, EGC area increased in the highlands(>1000 m)(+30%), whereas at low and middle elevations(Hiatus onset. In spite of growth depression, during Hiatus GI was higher than that in pre-warming period. At high elevation, GI positively responded to elevated June temperatures and negatively to moisture increase(precipitation, root zone moisture content, VPD, and SPEI). At low elevation GI negatively responded to June temperatures and positively to moisture increase. For both, low and high elevation, these patterns persisted throughout the study period(1967–2014). On the contrary, at middle elevations GI dependence on climate variables switch after breakpoint year(1983). Before breakpoint, June air temperature(positive correlation) and moisture(negative correlations) controlled GI. Further temperature increase leads GI depression and switched correlation signs to opposite(from positive to negative with tempe

Foreign body ingestion is a common complaint in gastrointestinal clinics. It is usually not difficult to diagnose because most of the patients report a definitive history of accidental foreign body ingestion. However, in rare cases, patients do not have a clear history. Thus, the actual condition of the patient is difficult to diagnosis or is misdiagnosed; consequently, treatment is delayed or the wrong treatment is administered, respectively. This report describes a fatal case of esophageal perforation caused by an unknowingly ingested fishbone, which resulted in lower esophageal necrosis, chest cavity infection, posterior mediastinum fester, and significant upper gastrointestinal accumulation of blood. However, his clinical symptoms and imaging data are very similar with esophageal hiatal hernia. Unfortunately, because the patient was too late in consulting a physician, he finally died of chest infection and hemorrhage caused by thoracic aortic rupture. First, this case report underlines the importance of immediate consultation with a physician as soon as symptoms are experienced so as not to delay diagnosis and treatment, and thus avoid a fatal outcome. Second, diagnostic imaging should be performed in the early stage, without interference by clinical judgment. Third, when computed tomography reveals esophageal Hiatus hernia with stomach incarceration, posterior mediastinal hematoma, and pneumatosis caused by esophageal, a foreign body should be suspected. Finally, medical professionals are responsible for making people aware of the danger of foreign body ingestion, especially among children, those who abuse alcohol, and those who wear dentures, particularly among the elderly, whose discriminability of foreign bodies is decreased, to avoid dire consequences.
