Adjoint of the Global Eulerian Lagrangian Coupled Atmospheric transport model (A-GELCA v1.0): development and validation

Abstract. We present the development of the Adjoint of the Global Eulerian–Lagrangian Coupled Atmospheric (A-GELCA) model that consists of the National Institute for Environmental Studies (NIES) model as an Eulerian three-dimensional transport model (TM), and FLEXPART (FLEXible PARTicle dispersion model) as the Lagrangian plume diffusion model (LPDM). The tangent and adjoint components of the Eulerian model were constructed directly from the original NIES TM code using an automatic differentiation tool known as TAF (Transformation of Algorithms in Fortran; http://www.FastOpt.com), with additional manual pre- and post-processing aimed at improving the performance of the computing, including MPI (Message Passing Interface). As results, the adjoint of Eulerian model is discrete. Construction of the adjoint of the Lagrangian component did not require any code modification, as LPDMs are able to track a significant number of particles back in time and thereby calculate the sensitivity of observations to the neighboring emissions areas. Eulerian and Lagrangian adjoint components were coupled at the time boundary in the global domain.The results are verified using a series of test experiments. The forward simulation shown the coupled model is effective in reproducing the seasonal cycle and short-term variability of CO2 even in the case of multiple limiting factors, such as high uncertainty of fluxes and the low resolution of the Eulerian model. The adjoint model demonstrates the high accuracy compared to direct forward sensitivity calculations and fast performance. The developed adjoint of the coupled model combines the flux conservation and stability of an Eulerian discrete adjoint formulation with the flexibility, accuracy, and high resolution of a Lagrangian backward trajectory formulation. </jats:p

Relations of angiotensin-(1-7) with hemodynamic and cardiac structural and functional parameters in patients with hypertension and type 2 diabetes

Background. The angiotensin-(1-7) is a new component of the renin-angiotensin system, the product of the degradation of angiotensin II and its functional antagonist, but its role in hypertension with type 2 diabetes (T2D) is not clear. The aim of the study was to investigate the levels of angiotensin-(1-7) in patients with hypertension and T2D and determine its relations to hemodynamic and cardiac structural and functional parameters. Material and methods. We examined 70 patients with hypertension and T2D. Investigation protocol included physical examination, standard transthoracic echocardiography and determination of the angiotensin-(1-7) blood levels by ELISA. Control group consisted of 16 healthy volunteers. Results. The angiotensin-(1-7) levels in observed patients were significantly lower than in volunteers [105.51 (89.13;121.17) ng/L vs. 132.75 (125.06; 142.87) ng/L, p &lt; 0.001]. The levels of the angiotensin-(1-7) significantly negatively correlated with duration of hypertension (r = –0.29, p &lt; 0.05), systolic blood pressure (BP) (r = –0.38, p &lt; 0.05), diastolic BP (r = –0.36, p &lt; 0.01), average BP (r = –0.32, p &lt; 0.01), left ventricular (LV) internal dimension at end-diastole (r = –0.37, p &lt; 0.01), LV mass (r = –0.40, p &lt; 0.001), LV mass index (r = –0.41, p &lt; 0.001). In patients with LV hypertrophy, angiotensin-(1-7) levels were significantly lower than in patients without LV hypertrophy [101.9 (88.2; 117.7) ng/L vs. 129.3 (117.5; 136.8) ng/L, p &lt; 0.01] and in patients with diastolic LV dysfunction — lower than in the patients with normal diastolic function [101.1 (87.9; 116.6) ng/L vs. 121.1 (105.5; 128.9) ng/L, p &lt; 0.01]. Conclusions. The angiotensin-(1-7) can be considered as an important pathogenetic factor in the development of hypertension with T2D, a BP regulator and a cardioprotective agent that prevents the development of remodeling and diastolic dysfunction of the LV

Hemo-biochemical component in dogs’ pancreatitis dynamics

Input: Pancreatitis – aseptic inflammation of pancreas of demarcation character, which is based on necrobiosis processes of pancreatocytes and fermental autoaggression followed by necrosis, glandular degeneration and secondary infection development (patent RU 2305844). Lipidemia – increased content of lipids in blood is one of the main causes of pancreatitis development. The aim of research became - evaluation of therapeutic efficacy of a medicine that based on beta-sitosterol and polyprenyl phosphates (BSPP). Objectives: Twenty sick dogs with diagnosis of pancreatitis and lipidemia served as a material of research. Dogs were divided into 2 groups of 10 animals in each according to the principle of analogues. Pancreatitis therapy of first animal group was carrying out by drugs of protease inhibitor group, H-2 histamine receptors blockers, and also antibioticotherapia. Methods: haematological, biochemical, statistical. Results: Before therapy beginning both groups had an increased hematocrit, number of erythrocytes and hemoglobin. Increased number of leucocytes was marked. After 14-th day therapy all hematological indicators returned to the reference values in both groups of animals. By biochemical research at the beginning of the treatment increased level of a-amylase, pancreatic lipase glucose, cholesterol and triglycerides had been marked. On completion of therapy (2 months) in both groups, indicators of α-amylase and glucose were within reference values. Level of cholesterol and triglycerides had returned to normal by that time in the second group of animals, which indicated the normalization of lipid metabolism. Whereas in the first group of animals these indicators remained high. Discussion: Inclusion in the scheme of therapy in acute pancreatitis protease inhibitors, H-2 histamine receptors blockers and antibiotics don’t allow to achieve complete recovery as evidenced by the high content of cholesterol and triglycerides. This promotes further transition of process to a chronic form. Inclusion of BSPP in the therapy in pancreatitis of dogs achieves significant depression of cholesterol and triglycerides in the serum of blood, thereby prevent relapses of disease

A PMT-Block test bench

The front-end electronics of the ATLAS hadronic calorimeter (Tile Cal) is housed in a unit, called {\it PMT-Block}. The PMT-Block is a compact instrument comprising a light mixer, a PMT together with its divider and a {\it 3-in-1} card, which provides shaping, amplification and integration for the signals. This instrument needs to be qualified before being assembled on the detector. A PMT-Block test bench has been developed for this purpose. This test bench is a system which allows fast, albeit accurate enough, measurements of the main properties of a complete PMT-Block. The system, both hardware and software, and the protocol used for the PMT-Blocks characterisation are described in detail in this report. The results obtained in the test of about 10000 PMT-Blocks needed for the instrumentation of the ATLAS (LHC-CERN) hadronic Tile Calorimeter are also reported.Comment: 23 pages, 10 figure

Жизнь напоказ: почему сегодня важно выставлять свои действия в социальной сети

Social networks have emerged relatively recently in human life, but have already become an integral part of it. Companies tell about themselves, their activities, innovations, promotions and events in their profiles. This helps increase audience coverage, tell more about your brand, products, services. People in personal accounts have the opportunity to share their lives and creativity through photos, videos and texts. Now it is not necessary to receive higher education to become an operator, director or actor whose talent is recognized by society. It is enough to start a page on the social network and start sharing your knowledge and creativity.To find out why people post photos, videos and write texts on their social networks, a pilot sociological study was carried out. The method of deep interview with active users of social networks was chosen to carry out the study. The interview allowed getting unique information, to learn the opinion of users about social networks, the impact of the new way of communication on their life, to identify the reasons why users start and maintain profiles.The respondents were 20 users of social networks between the ages of 19 and 22. Interviewees have profiles on the most popular Instagram and Vkontakte networks. As a result of the analysis of the interview, a tendency was revealed to differ in the perception of users of their actions on the social network and similar actions of other users. Their content is perceived by them as opportunities to be in sight, as a resource to form their social status and an element of influence on their reference group. And the same content published by others is perceived as boasting. Социальные сети появились в жизни человечества сравнительно недавно, но уже стали неотъемлемой ее частью. Компании рассказывают о себе, своей деятельности, новинках, акциях и мероприятиях в своих профилях. Это помогает увеличить охват аудитории, больше рассказать о своем бренде, продуктах, услугах. У людей в личных аккаунтах появилась возможностью делиться своей жизнью и творчеством с помощью фотографий, видео и текстов. Теперь не обязательно получать высшее образование, чтобы стать оператором, режиссером или актером, чей талант признает общество. Достаточно завести страницу в социальной сети и начать делиться своими знаниями и творчеством.Чтобы выяснить, зачем люди выкладывают фотографии, видео и пишут тексты в своих социальных сетях, было проведено пилотное социологическое исследование. Для проведения исследования был выбран метод глубинного интервью с активными пользователями социальных сетей. Интервью позволило получить уникальную информацию, узнать мнение пользователей о социальных сетях, влиянии нового способа коммуникации на их жизнь, выявить причины, по которым пользователи завели и ведут профили.Респондентами стали 20 пользователей социальных сетей в возрасте с 19 до 22 лет. Опрошенные имеют профили в наиболее популярных сетях Instagram и Вконтакте. В результате анализа интервью была выявлена тенденция различия в восприятии пользователями своих действий в социальной сети и аналогичных действий других пользователей. Свой контент воспринимается ими как возможности быть на виду, как ресурс формирования своего социального статуса и элемент влияния на свою референтную группу. А тот же контент, опубликованный другими, воспринимается как хвастовство и понты
