Automated Detection and Depth Determination of Melt Ponds on Sea Ice in ICESat-2 ATLAS Data — The Density-Dimension Algorithm for Bifurcating Sea-Ice Reflectors (DDA-bifurcate-seaice)
Authors: Herzfeld Ute , Trantow Thomas , Han Huilin , Buckley Ellen , Farrell Sinead , Lawson Matthew 
Published: October 2022

<p>As climate warms and the transition from a perennial to a seasonal Arctic sea-ice cover is imminent, understanding melt ponding is central to understanding changes in the new Arctic. NASA's Ice, Cloud and land Elevation Satellite (ICESat-2) has the capacity to provide measurements and monitoring of the onset of melt in the Arctic and on melt progression. Yet ponds are currently not reported on the ICESat-2 standard sea-ice products because of the low resolution of the products, in which only a single surface is determined.</p>
<p>The objective of this paper is to introduce a mathematical algorithm that facilitates automated detection of melt ponds in ICESat-2 ATLAS data, retrieval of two surface heights, pond surface and bottom, and measurements of depth and width of melt ponds. With the Advanced Topographic Laser Altimeter System (ATLAS), ICESat-2 carries the first space-borne multi-beam micro-pulse photon-counting laser altimeter system, operating at 532~nm frequency. ATLAS data are recorded as clouds of discrete photon points. The Density-Dimension Algorithm for bifurcating sea-ice reflectors (DDA-bifurcate-seaice) is an auto-adaptive algorithm that solves the problem of pond detection near the 0.7m nominal alongtrack resolution of ATLAS data, utilizing the radial basis function for calculation of a density field and a threshold function that automatically adapts to changes in background, apparent surface reflectance and some instrument effects. The DDA-bifurcate-seaice is applied to large ICESat-2 data sets from the 2019 and 2020 melt seasons in the multi-year Arctic sea-ice region. Results are evaluated by comparison to those from a manually forced algorithm.</p>

Objectives: The study compared the outcomes of VP shunt at Choudhary’s vs Keen’s point.
Material and Methods: A quasi-observational study was conducted on 50 patients who presented to NS-2, PINS, with the complaint of hydrocephalus. The study was conducted for 3 months from 1st November 2021 to 31th Jan 2022.
Results: Mean age was 40 years. In 25 (50%) patients, VP shunts were done through Choudhary’s point while in 25 (50%) patients VP shunts were done through Keen’s point. All patients were evaluated on day 3rd POD, 7th POD, 15th POD, and 90th POD. All patients were improved on 3rd POD. On the 7th POD, 15 (30%) patients deteriorated and showed signs of raised ICP. In these patients, the upper end of VP shunts is again revised due to blockage. On 15th POD, the upper end of VP shunts was blocked in 3 (6%) patients and their upper end was revised. On 90th POD, 2 (4%) patients were presented with upper-end blockage, and again shunt revision was done. VP shunts in all these patients were done through keen’s point approach. Blockage of the lower end of VP shunt occurred in 10% of patients in which 8% were operated through Keen’s point approach while resting 2% of patients were operated through Choudhary’s point approach.
Conclusion: VP shunts through Choudhary’s point approach yield good results as compared to Keen's point approach. This site is described by professor Muhammad Anwar Choudhary, as more convenient for insertion of VP shunt.

Objective: In this study, we looked at how intra-operative epidural steroids affected postoperative pain and stay duration in patients with unilateral single-level lumbar discectomy.
Material & Methods: A randomized control trial was conducted at Ayub Teaching Hospital Abbottabad. Group A (n = 30) was given intraoperative epidural methylprednisolone, while group B (n = 30) was given normal saline only. The outcome was measured between the two groups in terms of postoperative pain (visual analog scale), time of mobilization, length of hospital stay, and duration to return to work.
Results: At discharge, the VAS score in group A was 0.40 compared to 2.4 in group B (p = 0.000). At 2 weeks follow-up, the mean VAS score was 1.10 in group A in contrast to 1.4 in group B (p = 0.001). Patients who received local epidural methylprednisolone were mobilized after an average of 1 day, stayed for an average of 1.16 days, and returned to work following 18.2 days, whereas patients in the control group were mobilized after an average of 1.2 days, stayed for an average of 1.86 days and returned to work following 25.9 days. An incidental Dural tear occurs in 2 cases.
Conclusion: Intra-operative epidural steroid is beneficial in reducing post-operative pain, hospital stay, and time to return to work. It allows early mobilization with enhanced recovery and few complications.

Correlation Between Soil Nitrogen Content and NDVI Derived from Sentinel-2A Satellite Imagery
Authors: Trigunasih Ni Made , Saifulloh Moh 
Published: October 2022

The United Nations Educational, Scientific, and Cultural Organization (UNESCO) has recognized the Balinese agricultural irrigation system known as subak as part of the world's cultural heritage. Subak is the driver of Bali’s agricultural and tourism sectors and, therefore, must be preserved. Population growth triggers the conversions of land functions, from subak to built-up lands, such as those transpiring in Denpasar City. On the other hand, with the population continuously increasing, the demand for food becomes inevitably higher. This has caused farmers to intensify their agricultural practices through, for instance, applying chemical fertilizers excessively-potentially decreasing soil fertility. An example is urea fertilizer that contains a macronutrient, i.e., nitrogen (N). This study aimed to analyze the soil N content and its correlation with rice growth using the Normalized Difference Vegetation Index (NDVI). The Kjeldahl method was conducted to measure the N levels in the soil laboratory. NDVI was extracted from remote sensing data, namely Sentinel-2A imagery, on a cloud computing platform, Google Earth Engine (GEE), using Band 8 (NIR) with a wavelength of 0.842 m and Band 4 (Red) with 0.665 m. The results showed that the N levels varied from 0.09% to 0.31% and the average NDVI values ranged from 0.47 to 0.54. There is a strong correlation (r = 0.75 to 0.78) between the NDVI values derived from the Sentinel-2A Satellite Imagery and the soil nitrogen content. Spatially, based on the analysis results of the 2019‒2021 data, parts of existing subak systems, i.e., Subak Kerdung, Mergaya, Padanggalak, and Sembung, have high soil N contents and NDVI values.

Authors: Cui Zhilei , Zhang Linlin , Song Lin 
Published: October 2022

Introduction: Non-small cell lung cancer (NSCLC) is the most prevalent type of cancer worldwide and associated with high mortality rate. An effective treatment for NSCLC is urgently needed. This study aimed to investigate differences of inflammatory microenvironment and sensitive correlation to cisplatin-chemotherapy in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC), thereby providing insights into the mechanisms underlying inflammation in NSCLC.
Materials and methods: The resistance of A549 and SK-MES-1 cells to cisplatin treatment was determined by IC50. The migration and invasion capacity of A549 and SK-MES-1 cells was determined using migration and invasion assay kits. The apoptosis rate was evaluated. The protein expression levels of caspase-3 and Ki67 were measured by western blot. ELISA assay was used to determine the levels of inflammatory cytokines, including IL-4, IL-6, IL-8, and TNF-α.
Results: Patients with LUAD showed shorter survival than LUSC patients after the chemotherapy treatment. LUAD was more resistant to cisplatin treatment, corresponding with a higher IC50 observed in A549 cells than SK-MES-1 cells. Moreover, A549 cells showed higher migration and invasion capacity and lower apoptosis rate than SK-MES-1 cells. In addition, SK-MES-1 LUAD samples showed stronger inflammation response than LUAD samples and A549 cells. Accordingly, inflammation cytokines promoted the migration and invasion of SK-MES-1 cells, whereas inhibited cell apoptosis.
Conclusions: The present study suggests that LUAD is more resistant to chemotherapy and shows a stronger inflammation response than LUSC. Inflammatory cytokines could enhance the resistance of LUAD to chemotherapy and further promote tumor cell proliferation, migration, and invasion.
