The interdecadal change of the summer (July–August) rainfall over North China (SRNC) is great concern to climate research community. Based on sliding correlation and difference analysis, SRNC was studied. Results show a significantly wetter period since mid-2000s, which associated with strengthening negative relationship between PDO. PDO affected through jet stream in upper-level East Asia–Paci...
The history of any profession relates to the history of the division of labour in society. This is generally true and can also be attributed to expertise in the financial world a world which generates with increasing complexity growing numbers of specialists offering know-how and expertise. The competition amongst these different specialists as to whose services are the more useful, valuable or...
Increasing atmospheric carbon dioxide (CO2) is the principal driver of anthropogenic climate change. Asia is an important region for the global carbon budget, with 4 of the world's 10 largest national emitters of CO2. Using an ensemble of seven atmospheric inverse systems, we estimated land biosphere fluxes (natural, land-use change and fires) based on atmospheric observations of CO2 concentrat...
Knee osteoarthritis (OA) is believed to be highly prevalent today because of recent increases in life expectancy and body mass index (BMI), but this assumption has not been tested using long-term historical or evolutionary data. We analyzed long-term trends in knee OA prevalence in the United States using cadaver-derived skeletons of people aged ≥50 y whose BMI at death was documented and who l...
For each quartile of income per consumption unit, annual time-series have been estimated from panel surveys, with annual waves of observations since 1974: INSEE Households' Continuous survey from 1974 to 1994, Sofres “Parc-Auto” panel survey since 1994. In these data sources, household behaviour is described through: car ownership (percentages of households with at least one car, and of multi-c...
A contrasting trend pattern of sea surface salinity (SSS) between the western tropical Pacific (WTP) and the southeastern tropical Indian Ocean (SETIO) is observed during 2004-2013, with significant salinity increase in the WTP and freshening in the SETIO. In this study, we show that increased precipitation around the Maritime Continent (MC), decreased precipitation in the western-central tropi...
[1] As the upper layer of the world ocean warms gradually during the 20th century, the inter‐ocean heat transport from the Indian to Atlantic basin should be enhanced, and the Atlantic Ocean should therefore gain extra heat due to the increased upper ocean temperature of the inflow via the Agulhas leakage. Consistent with this hypothesis, instrumental records indicate that the Atlantic Ocean ha...
We present results of ultra-deep ISOCAM observations through a cluster-lens at 7μm and 15μm with the Infrared Space Observatory (ISO) satellite. These observations reveal a large number of luminous Mid-Infrared (MIR) sources. Crossidentification in the optical and Near-Infrared (NIR) wavebands shows that about half of the 7 μm sources are cluster galaxies. The other 7 μm and almost all 15 μm so...
در این پایان نامه به بررسی نامساوی های نیمه تغییراتی- تغییراتی با شرایط مرزی نیومن ناهمگن خواهیم پرداخت. فصل اول شامل تعاریف، مفاهیم و قضایای مقدماتی است و فصل دوم به بیان و بررسی قضیه نقاط بحرانی که در فصل های بعدی کاربرد زیادی دارد، اختصاص یافته است. در فصل سوم با استفاده از قضیه نقاط بحرانی، وجود دنباله ای بی کران از جواب های ضعیف، برای معادلات بیضوی شاملp - لاپلاس را بررسی خواهیم کرد. در فص...
نامساوی ها یکی از مهمترین حوزه های پژوهشی آنالیز ماتریسی هستند که از ابتدا مورد علاقه بسیاری از ریاضی دانان بوده و کاربردهایی در علوم مختلف از جمله محاسبات علمی، نظریه سیستم و کنترل، تحقیق در عملیات، فیزیک ریاضی، استاتیک، اقتصاد و مهندسی دارد. نخستین بار در سال $1934$ کتاب تقریبا جامعی با نام "نامساوی ها" cite{h} توسط هاردی، ltrfootnote{g. h. hardy} لیتل وود ltrfootnote{e. little...
