On the metric of the jet bundle and similarity on Dirichlet spaces

In general, it is more difficult to formulate a sufficient condition for similarity than a necessary condition. We give a sufficient condition for a Cowen-Douglas operator with a positivity condition to be similar to the backward shift operator on weighted Dirichlet space. This condition involves the holomorphic jet bundle of the eigenvector bundle of the operator

Comparison Of Interpolation Technique For Rain Gauge Data Through The Distributed Rainfall-Runoff Model

Precipitation estimated from different measuring techniques such as rain gauge, radar and satellite have some similarities, but there are also differences among them. For example, techniques based on radar and satellite data underestimate rainfall than those using rain gauge data. In addition, many different interpolation techniques have been used to measure spatial pattern of precipitation but it is still difficult to have an accurate pattern by any one of them. The differences between the rainfall estimates from different techniques vary seasonally as well as regionally so that the radar or satellites are not directly applied into hydrologic analysis. In this regard, a main objective of this study is to develop a systematic way to interpolate ground rain gauge using discharge data from distributed rainfall-runoff model The spatial rainfall patterns estimated from the interpolation methods will be evaluated with the object function to minimize the difference between observed and estimated discharge. In other words, this study seeks to identify the optimal spatial pattern in rain field that can generate a similar pattern of observed discharge through the distributed rainfall-runoff model. This study will compare the spatial pattern from different types of climate systems and different seasons derived from different interpolation methods may help to validate the proposed algorithms

Human dopamine receptor nanovesicles for gate-potential modulators in high-performance field-effect transistor biosensors

The development of molecular detection that allows rapid responses with high sensitivity and selectivity remains challenging. Herein, we demonstrate the strategy of novel bio-nanotechnology to successfully fabricate high-performance dopamine (DA) biosensor using DA Receptor-containing uniform-particle-shaped Nanovesicles-immobilized Carboxylated poly(3,4-ethylenedioxythiophene) (CPEDOT) NTs (DRNCNs). DA molecules are commonly associated with serious diseases, such as Parkinson's and Alzheimer's diseases. For the first time, nanovesicles containing a human DA receptor D1 (hDRD1) were successfully constructed from HEK-293 cells, stably expressing hDRD1. The nanovesicles containing hDRD1 as gate-potential modulator on the conducting polymer (CP) nanomaterial transistors provided high-performance responses to DA molecule owing to their uniform, monodispersive morphologies and outstanding discrimination ability. Specifically, the DRNCNs were integrated into a liquid-ion gated field-effect transistor (FET) system via immobilization and attachment processes, leading to high sensitivity and excellent selectivity toward DA in liquid state. Unprecedentedly, the minimum detectable level (MDL) from the field-induced DA responses was as low as 10 pM in real- time, which is 10 times more sensitive than that of previously reported CP based-DA biosensors. Moreover, the FET-type DRNCN biosensor had a rapid response time (<1 s) and showed excellent selectivity in human serum

New Classification of Polydactyly of the Foot on the Basis of Syndactylism, Axis Deviation, and Metatarsal Extent of Extra Digit

Background  Polydactyly of the foot is one of the most frequent anomalies of the limbs.However, most classification systems are based solely on morphology and tend to be inaccu­rate and lessrelevantto surgical methods and results. The purpose ofthisstudy isto presentour newclassification of polydactyly ofthe foot,which can serve as a predictor oftreatmentand prognosis.Methods  To find a correlation between the various morphologic traits of polydactyly ofthe foot and the treatment plan and outcomes,we reviewed 532 cases of polydactyly ofthefoot in 431 patients treated in our hospital, expanding on our previous study that describedpolydactyly based on the importance of metatarsal bone status and varus deformity. Therecords of patientswere evaluated and comparedwith previousstudies at other centers.Results  Unsatisfactory results were seen in 36 cases, which included 5 cases of incompleteseparation due to syndactylism, 23 cases of axis deviation, and 8 cases ofremnants of extra­digit metatarsal bones. The locus of the polydactyly, or the digit which wasinvolved, did notseemto affectthe final postoperative outcomesin ourstudy. Three factors­syndactylism, axisdeviation, and metatarsal extension­are the major factors related to treatment strategy andprognosis. Therefore,we developed a newclassification systemusing three characters(S,A,M)followed by three groups(0, 1, 2),to describe the complexity of polydactyly ofthe foot,suchas S1A2M2.Conclusions  Our newclassification could provide a communicable description to help deter­mine the surgical plan and predict outcomes

The effect of heating insufflation gas on acid-base alterations and core temperature during laparoscopic major abdominal surgery

BACKGROUND: Carbon dioxide (CO(2)) has different biophysical properties under different thermal conditions, which may affect its rate of absorption in the blood and the related adverse events. The present study was aimed to investigate the effects of heating of CO(2) on acid-base balance using Stewart's physiochemical approach, and body temperature during laparoscopy. METHODS: Thirty adult patients undergoing laparoscopic major abdominal surgery were randomized to receive either room temperature CO(2) (control group, n = 15) or heated CO(2) (heated group, n = 15). The acid-base parameters were measured 10 min after the induction of anesthesia (T1), 40 min after pneumoperitoneum (T2), at the end of surgery (T3) and 1 h after surgery (T4). Body temperature was measured at 15-min intervals until the end of the surgery. RESULTS: There were no significant differences in pH, PaCO(2), the apparent strong ion difference, the strong ion gap, bicarbonate ion, or lactate between two groups throughout the whole investigation period. At T2, pH was decreased whereas PaCO(2) was increased in both groups compared with T1 but these changes were not significantly different. Body temperatures in the heated group were significantly higher than those in the control group from 30 to 90 min after pneumoperitoneum. CONCLUSIONS: The heating of insufflating CO(2) did not affect changes in the acid-base status and PaCO(2) in patients undergoing laparoscopic abdominal surgery when the ventilator was set to maintain constant end-tidal CO(2). However, the heated CO(2) reduced the decrease in the core body temperature 30 min after the pneumoperitoneum.ope
