Web Omnidirectional Image Viewer for Field Event Extraction

A Web-based image viewer for observing an omnidirectional image of fields is proposed. Conventional monitoring systems are monitoring a narrow area of fields, and their image viewers are not optimized for comparing accumulated images. We implemented two functions of the viewer to compare images and conducted an experiment to evaluate their performance. The experimental results showed that Time-travel mode, which partially shows another image in a circular region on an omnidirectional image, had a high degree of usability for extracting field events from accumulated images. The proposed system can help farmers capture comprehensive, panoramic views of their farm for field management.</jats:p

Tunic Cell Morphology and Classification in Botryllid Ascidians(Morphology)

The morphology of tunic cells was investigated in ten botryllid ascidians, six Botryllus and four Botrylloides species, by means of light and electron microscopy. Three types of tunic cells were described, I.e. amoeboid, vacuo-granular and large granule tunic cells. Amoeboid tunic cells were irregularly shaped, and had many pseudopodia. They were found in the all species studied here. Vacuo-granular tunic cell had many vacuoles which contained round granules, and was found in four Botryllus and four Botrylloides species. The diameters of the granules varied amond species (ca. 1.4-0.8 ^m). Large granule tunic cells were peculiar to Botryllus scalaris, and each of them contained a single large granule with lamellate substructure. Some tunic cells showed intermediate characteristics of amoeboid and vacuo-granular tunic cells. It seems that amoeboid tunic cells probably differentiate into vacuo-granular tunic cells in the tunic. There are thread-like bacteria in the tunic, and they often dangle around vacuo-granular tunic cells. There may be some interactions between tunic cells and the bacteria

Sodium temperature lidar based on injection seeded Nd:YAG pulse lasers using a sum-frequency generation technique

We report on a sodium (Na) temperature lidar based on two injection seeded Nd:YAG pulse lasers using single-pass sum-frequency generation. The laser power at 589 nm is 400 mW (40 mJ per pulse at a repetition rate of 10 Hz) and the pulse width is 22 nsec FWHM. The narrowband laser tuned to the Doppler broadened Na D(2) spectrum enables us to measure the temperature of the mesopause region (80-115 km). This solid-state transportable system demonstrated high performance and capability at Syowa Station in Antarctica for 3 years and at Uji in Japan for an additional year without any major operational troubles.

First mesopause temperature measurements using sodium lidar observations in the Antarctic region

The mesopause temperature structure was observed using a sodium temperature lidar system at Syowa Station (69°00\u27 S, 39°35\u27 E), beginning in February 2000. The laser transmitter was newly developed and included two injection-seeded Nd: YAG lasers. Regular observations were performed using the two-frequency technique as demonstrated by C.Y. She et al. (Geophys. Res. Lett., 17, 929, 1990), with a spatial resolution of about 1 km and a temporal resolution of 6 min. The temperature structures of the 85km to 105km region of the upper atmosphere were measured by Na D_2 Doppler profile-fitting as well as the two-frequency technique. Temperatures derived from the two techniques agreed well and were consistent with the MSIS 90 model temperature structure. Night-time temperature variations over a 15-hour period were measured in May 2000. A large temperature fluctuation with an interval of about 4 hours, and an amplitude of 60 K (probably caused by gravity waves) was observed. From the average night temperature profile, the mesopause was determined to be located at 102km, and have a temperature of 180K. These values are similar to winter values observed in the northern hemisphere

Sodium temperature lidar observation at Syowa Station: Summary of three-year observations and unusually high temperature in 2002

Total 223 nights (2002 hours) of temperature measurement in the mesopause region (80-105 km) was successfully done in wintertime at Syowa Station (69&ordm;S, 39&ordm;E) starting from 2000 through 2002. Monthly mean temperatures were calculated using nightly mean temperatures and year-to-year variation was examined. The monthly temperature of 2002 shows unusually higher (25 K and 20 K) in June and July compared with previous 2 years. Variations of individual nights showed the temperatures at 80 km, 85 km and 110 km are in good agreement among three years through the observation period. The temperature of 2002 began to increase from the middle of May and was back to normal around the end of July in the limited altitude range of 90-105 km

Extracorporeal membrane oxygenation in Stenotrophomonas maltophilia pneumonia during acute myeloid leukemia: A case report

Stenotrophomonas maltophilia (S. maltophilia) is a Gram-negative, multidrug-resistant organism that both opportunistically infects the bloodstream and leads to pneumonia in immunosuppressed patients, including those with hematologic malignancies. In patients with severe respiratory failure, venovenous extracorporeal membrane oxygenation (VV ECMO) can stabilize the respiratory status. However, whether ECMO in patients with hematologic malignancies improves the clinical outcomes is still controversial because ECMO increases the risk of the exacerbation of sepsis and bleeding. We report a case of a 46-year-old man with Stenotrophomonas maltophilia hemorrhagic pneumonia acquired during consolidation chemotherapy for acute myeloid leukemia in whom VV ECMO lead to a good clinical outcome. The stabilization of his respiratory status achieved with VV ECMO allowed time for trimethoprim-sulfamethoxazole antibiotic therapy to improve the pneumonia. We suggest the background of patients, including comorbidities and general conditions, should be taken into account when considering the clinical indications of ECMO

Relationship between clinical outcomes and nerve conduction studies before and after surgery in patients with carpal tunnel syndrome

Background Nerve conduction study (NCS) is the only useful test for objective assessment of carpal tunnel syndrome (CTS). However, the relationship between pre- and postoperative NCS and clinical outcomes was unclear. This study aimed to determine whether pre- and postoperative (6 months) NCS could predict patient-oriented and motor outcomes (6 and 12 months postoperatively) in patients with CTS. Method Of the 85 patients with CTS, 107 hands were analyzed from March 2011 to March 2020. All patients underwent open carpal tunnel release and were examined using the disabilities of the arm, shoulder and hand (DASH) questionnaire and grip strength (GS) preoperatively and 6 and 12 months postoperatively. Moreover, NCS was examined preoperatively and 6 months postoperatively. Distal motor latency (DML) and sensory conduction velocity (SCV) were the parameters used for NCS. The correlation coefficient between NCS and DASH or GS was calculated. A receiver operating characteristic curve was utilized to determine the NCS threshold value to predict DASH and GS improvement. Results The average scores of GS preoperatively and 6 and 12 months postoperatively were 21.3, 22.3, and 22.8, respectively. On the other hand, the average scores of DASH preoperatively and 6 and 12 months postoperatively were 28.8, 18.3, and 12.2, respectively. The average NCS scores (DML and SCV) preoperatively/6 months postoperatively were 7.3/5.4 and 27.8/36.7, respectively. Preoperative NCS did not correlate with DASH and GS. Postoperative SCV correlated with the change in grip strength (6–12 months, r = 0.67; 0–12 months, r = 0.60) and DASH (0–12 months, r = 0.77). Moreover, postoperative DML correlated with the change in DASH (6–12 months, r = − 0.33; 0–12 months, r = − 0.59). The prediction for the improvement of GS/DASH achieved a sensitivity of 50.0%/66.7% and a specificity of 100%/100%, at an SCV cutoff score of 38.5/45.0 or above. The prediction for improvement of GS/DASH achieved a sensitivity of 83.3%/66.7% and a specificity of 100%/66.7% at a DML cutoff score of 4.4/4.4 or below. Conclusion NCS at 6 months postoperatively can be used to predict the improvement of clinical outcome after 6 months postoperatively in patients with CTS
