In this paper, the continuous-time linear Gaussian smoothing problem is investigated by utilizing a dual approach. It is shown that the smoothing problem is a dual of an optimal regulator with a jump condition on the trajectory. By solving the dual optimal control problem, basic results established earlier on this smoothing problem are derived in a simpler way. Results are also obtained for the discrete-time linear smoothing Gaussian problem. 相似文献

Discrimination‐Related Stress Effects on the Development of Internalizing Symptoms Among Latino Adolescents 下载免费PDF全文

This three‐wave longitudinal study of 173 Latino adolescents (M = 16.16 years, SD = 0.65) is designed to understand the role of discrimination‐related stress in mental health trajectories during middle to late adolescence with attention to differences due to immigration status. The results of the growth curve analysis showed that anxious‐depressed, withdrawn‐depressed, and somatic complaints significantly decreased over time. Furthermore, although discrimination‐related stress was found to be significantly related to the trajectories of three types of mental health symptoms, the results revealed that immigration status moderated these relations such that discrimination‐related stress was significantly related to these outcomes for Latino youth whose parents were born in the United States, while this relation was not significant for Latino children of immigrants. 相似文献

Lymphatic filariasis continues to be the major cause of clinical morbidity in India and other developing tropical countries.
One of the major lacunae in the effective management of clinical filarial cases is the non-availability of a suitable diagnostic
test for confirming filaria aetiology in acute, chronic and occult clinical cases where microfilariae (mf) are not usually
seen in peripheral circulation. Studies in our laboratory have shown the usefulness of filarial antibody and antigen assays
using microfilarial excretory-secretory (mf ES) antigen in detecting microfilaraemic, acute and chronic filarial cases and
in confirming filarial aetiology in occult infections. Diethylcarbamazine citrate (DEC) is the drug of choice for lymphatic
filariasis. Different regimens of DEC have been explored in the treatment of microfilaraemic cases. Immunomonitoring has shown
that the seroconversion of antigen and antibody positivity was found to be very helpful in determining appropriate period
of DEC treatment for clinical relief and cure in clinical filarial patients and further they did not have recurrence in most
of the cases. Optimal DEC (6mg/kg body wt/day for 21 days each month for 3–12 months) therapy was found to be very effective
in acute and atypical clinical manifestations such as asthmatic bronchitis, pulmonary eosinophilia, monoarthritis, recurrent
upper respiratory tract infections (URI), pneumonia (super imposed infections) in children and minimal hydrocele, epididymoorchitis,
lymphangitis, lymphadenitis, acute abdomen, central serous retinopathy, tenosynovitis, pain and swelling in limbs and joints
in adults living in filaria endemic areas. 相似文献

Diabetes has been classified as a disease of glucose overproduction by tissues, mainly liver and glucose underutilization
by insulin requiring tissues like liver, adipose and muscle due to lack of insulin. There is, however, glucose over utilization
in tissues not dependent on insulin for glucose transport like kidney, nerve and brain. There are serious complications due
to this excess glucose in these tissues and their reversal is important for a good metabolic control and normalisation of
other parameters. Insulin, trace metals and some plant extracts have been used to see the reversal effects of the complications
of diabetes in liver and kidney in experimental diabetes. Almost complete reversal of the metabolic changes has been achieved
in the activities of key enzymes of metabolic pathways in liver and kidney and an effective glucose control has been achieved
suggesting a combination of therapies in the treatment of metabolic disturbance of the diabetic state. 相似文献

Serum iron levels were studied in 50 patients with pre-eclampsia and the results were compared with 50 control cases. Their
serum iron levels were found to be higher than the controls. Increase in serum iron was directly proportional to the increased
levels of uric acid, urea and creatinine. Mean reticulocyte counts, plasma free haemoglobin and unconjugated bilirubin levels
were also higher in these patients. It is suggested that haemolysis may be a major contributory factor for the increased levels
of serum iron in pre-eclampsia. 相似文献

Metabolic syndrome contributes to pathogenesis of Type-2 diabetes and CAD. Insulin Resistance is the key factor of metabolic
syndrome implicated in development of Non Alcoholic Fatty Liver Disease (NAFLD). In present study we have investigated the
prevalence of NAFLD in metabolic syndrome and contribution of metabolic risk factors in causation of NAFLD in non-diabetic
North Indian male population. The study was conducted on 495 non-diabetic, nonalcoholic subjects (age 30–65 years). Metabolic
Syndrome was assessed by using ATP III and ADA (2005) criteria. Anthropometric factors-Waist circumference and blood pressure
were measured. Fasting serum samples were analyzed for Glucose, Triglycerides, Cholesterol and its fractions, Insulin, Alanine
transaminase, Aspartate transaminase, Gamma glutamyl transferase and free fatty acids. Insulin resistance was estimated by
Homeostasis Model and Insulin sensitivity by QUICKI Index. Liver ultrasonographic scanning was used for assessing fatty liver.
The prevalence of metabolic syndrome and NAFLD was 24% and 14.8% respectively in non-alcoholic population and 27% of metabolic
syndrome had NAFLD which was associated with hyperinsulinemia, insulin resistance, insulin insensitivity along with elevated
levels of waist circumference, blood pressure, triglyceride, FFA and decreased HDL-Cholesterol. The prevalence of NAFLD increased
with insulin resistance and clustering of metabolic risk factors. 相似文献

Cholesterol and phospholipids were estimated in serum and bile from hepatic duct and gallbladder of twenty five patients of gallstone with functioning gallbladder (Group-I) and an equal number of patients having diseases other than of hepatobiliary system acting as control (Group-II). Group-I patients showed high serum cholesterol and low serum phospholipid levels as compared to those of Group-II. Cholesterol levels in hepatic duct and gallbladder bile were higher in Group-I than in Group-II whereas the phospholipid levels in the bile of Group-I were lower than in Group-II. The phospholipid: cholesterol ratios in hepatic duct and gallbladder bile of Group-I were 2.76 and 3.03 respectively as compared to 5.62 and 5.92 in Group-II. 相似文献

This article presents an analysis of the way art is conceptualised in the British primary school curriculum and provides an historical framework that maps an evolution of ideas that have shaped the way art is presented in the modern day primary curriculum. In order to achieve this a Foucauldian style genealogical analysis is utilised to trace the discourses (systems of meaning) surrounding the nature of children's artistic development and how these discourses are used in the present day British primary curriculum to construe art in different ways. The analysis in this article is threefold. It explores the presentation of art in the curriculum as (1) an expressive subject, (2) a skills based subject, (3) a subject which focuses on art history and art appreciation. Second, the teaching positions associated with each approach are identified as follows (a) the facilitator, (b) the expert and (c) the philosopher; as well as the issues teachers face when adopting these positions. Third, attention is given to how these theoretical principles might be linked to practice. In so doing this article contributes to the debate surrounding the value of art in the primary curriculum and the way in which the curriculum serves to shape teaching practice. 相似文献
