Spreading of Antarctic Bottom Water examined using the CFC-11 distribution simulated by an eddy-resolving OGCM

We have investigated the spreading and pathway of Antarctic Bottom Water(AABW) using the simulated distribution of chlorofluorocarbons(CFCs) in a global eddy-resolving(1/10°) OGCM. Our goal is understanding of the processes and pathways determining the distribution of CFCs in the Southern Ocean, where much of this tracer is entrained by formation of deep and bottom water. The simu- lated high CFC-11 water reveals the newly formed AABW around the Antarctic Continent. The main source regions of AABW in the model are in the Weddell Sea(60°- 30°W ), offshore of Wilkes Land(120°- 160°E ) and in the Ross Sea(170°E -160°W ). In our model, spreading of simulated CFC-11 in the deep Southern Ocean from the newly formed AABW regions is more similar to the observed distribution than in coarse-resolution models. In the Weddell Sea, the high CFC-11 water spreads eastward with the Antarctic Circumpolar Current(ACC) and flows northward to the Argentine Basin. The high CFC-11 water from Wilkes Land joins with the high CFC-11 water from the Ross Sea. Some of the high CFC-11 water from Wilkes Land flows northward toward New Zealand. The high CFC-11 water from the Ross Sea flows eastward with the ACC along the Mid Ocean Ridge and northward to the Southeast Pacific Basin

Polaron Masses in CH₃NH₃PbX₃ Perovskites Determined by Landau Level Spectroscopy in Low Magnetic Fields

次世代太陽電池材料 ペロブスカイト半導体中の「電子の重さ」の評価に成功 --太陽電池やLED応用へ向けてさらなる期待--. 京都大学プレスリリース. 2021-06-14.We investigate the electron-phonon coupling in CH₃NH₃PbX₃ lead halide perovskites through the observation of Landau levels and high-order excitons at weak magnetic fields, where the cyclotron energy is significantly smaller than the longitudinal optical phonon energy. The reduced masses of the carriers and the exciton binding energies obtained from these data are clearly influenced by polaron formation. We analyze the field-dependent polaronic and excitonic properties, and show that they can be quantitatively reproduced by the Fröhlich large polaron model

Complete Dissection of a Hepatic Segment after Blunt Abdominal Injury Successfully Treated by Anatomical Hepatic Lobectomy: Report of a Case

A 21-year-old male patient was transferred to the emergency room of our hospital after suffering seat belt abdominal injury in a traffic accident. Abdominal computed tomography revealed a massive hematoma in the abdominal cavity associated with deep hepatic lacerations in the right lobe. The presence of a solid tissue possibly containing pneumobilia was observed above the greater omentum. These findings were consistent with a tentative diagnosis of hepatic laceration due to blunt trauma; therefore, this prompted us to perform emergency laparotomy. The operative findings revealed a massive hematoma and pulsatile bleeding from the lacerated liver and a retroperitoneal hepatoma, which was most likely due to subcapsular injury of the right kidney. In accordance with the preoperative imaging studies, a pale liver fragment on the greater omentum was observed, which was morphologically consistent with the defect in the posterior segment of the liver. Since the damaged area of the liver broadly followed the course of the middle hepatic vein, we carefully inspected and isolated the inflow vessels and eventually performed a right hepatic lobectomy. The patient's postoperative course was uneventful, and he was doing well at 10 months after surgery

Pictorial review Articular and Juxtaarticular Cystic Lesions: Evaluation with MR Imaging

MR imaging is the most appropriate imaging modality for the evaluation of articular or juxtaarticular cystic lesions. Most of the cystic lesions show a typical signal intensity pattern of fluid, but debris or hemorrhage within the cyst may alter the signal intensity pattern of the cyst. The location and relationship with the surrounding structure are important for the differential diagnosis of cystic lesions. Associated joint abnormalities that include meniscus or labral tears, ligamentous injury, degeneration, and inflammation should also be evaluated

Utility of a 21-gauge Menghini-type biopsy needle with the rolling method for an endoscopic ultrasound-guided histological diagnosis of autoimmune pancreatitis: a retrospective study

Background The histological diagnosis of autoimmune pancreatitis (AIP) by an endoscopic ultrasound (EUS)-guided approach is still challenging. Methods We investigated the utility of the 21-gauge Menghini-type biopsy needle with the rolling method for the histological diagnosis of AIP, in comparison with conventional 22-gauge needles. Among total 28 patients, rate of definitive histological diagnosis, acquired sample area of tissue, rate of histopathological diagnosis of AIP, and adverse events were retrospectively analyzed. Results Definitive histological diagnoses were successfully accomplished in all 14 patients (100%) treated with a Menghini-type needle, and in 57% of cases (8/14) treated with conventional 22-gauge needles (P  Conclusion EUS-guided rolling method with the 21-gauge Menghini-type biopsy needle is useful for the histopathological diagnosis of AIP, due to its abundant acquisition of good-quality tissue from the pancreas.</br

Miniature Space GPS Receiver by means of Automobile-Navigation Technology

Miniature space GPS receivers have been developed by means of automobile-navigation technology. We expanded the frequency sweep range in order to cover large Doppler shift on orbit. The GPS receiver was modified to output pseudorange data with accurate time tag. We tested the performance in low earth orbits by means of a GPS simulator. The range error caused by the receiver is measured to be 0.9 meter in RMS. Receiver was on-boarded on INDEX (“REIMEI”) satellite, which was launched in 2005. Cold start positioning was confirmed repeatedly to finish within 30 minutes on orbit. The orbit determination was performed to evaluate the random position error of GPS receiver by means of the residual error. The random error of GPS position is as large as 2 meter for PDDP=2.5 on orbit. The RMS value of range error is evaluated to be 0.6m from the flight data. These results on orbit are consistent with the simulation results in use of a GPS simulator. This miniature space GPS receiver is at present in commercial market

MR Imaging of Intra-articular / Juxta-articular Mass Lesions

A wide variety of pathologies can arise in intraarticular/ juxta-articular region. This can be a potential source of confusion in a clinical set-up. These entities are diverse in origin and can emanate from bone, synovium, soft tissue and other surrounding structures. The purpose of this essay is to present an overview of imaging features of these entities with emphasis on the usefulness and limitations of the magnetic resonance imaging (MRI) in the work-up. For the purpose of description the lesions are divided on the basis of their origin in separate groups
