Abstract
Landsat-8 has various channels that function to identify an object. The vegetation index algorithm which is based on remote sensing involves several bands and can describe the percentage of canopy and density of vegetation. More than 100 vegetation index algorithms and each can be used in accordance with the research objectives. In this paper we will discuss the utilization of Landsat-8 metric data with the parameters of Normalized Difference Vegetation Index (NDVI) and Normalized Burn Ratio (NBR) and several parameters in metric data with various features to produce indications of rapid land change, especially to detect changes in tree cover area to lose tree cover and vice versa. For this purpose, the annual Landsat-8 metrics data is located in Riau Province. To compare both NDVI and NBR parameters, the trial and error method is used and the results are compared visually to the two different images of the year. The result is that the NBR parameters with a maximum-70 feature and the threshold for tree cover loss and tree cover gain respectively more than -0.1 provide tangible results in looking at the tree cover changes in Riau Province. In the analysis, other information is needed, for example, a map of the Forest Area to see further whether the changes that occur are in the forest area or not, which will certainly provide different treatment.

Abstract

The city of Surabaya is the second largest city in Indonesia which still has active wetlands in the form of mangrove and ponds cultivation areas. This wetland has an important contribution to the environmental balance, protection of biodiversity, as well as maintaining the ecological function of the urban area to continue properly. Specifically this region contributes to surface water control which is an absolute prerequisite for the sustainability of settlements in urban zones. Urbanization and economic dynamics continue to drive increasingly highly demands of land, so that wetland areas continue to experience pressure and turn into built-up land use. The spatial dynamics model of land use change is one of the important instruments that can be used to analysis of urban dynamics complexes. This model using 2 methods in stages. First, the spatial data mining (SDM) method used to determine indicators of agents that contribute on the fragmentation of wetlands. Second, the integration method of Markov Change and Cellular Automata (CA) models for spatial land use projection. The results showed that the integration of SDM methods and Markov-CA contributed significantly to improving the accuracy of the results of land use projection. This model is then referred to as guided spatial projection where the process of urban sprawl can be shown to be more rational and logical. The results of the research are projections of the dynamics of land use that are used as input in calculating the surface runoff as one indicator of sustainability for urban settlements.

Abstract
The Banda Islands consist of three main islands namely Banda Besar Island, Banda Naire Island, and Banda Api Island. Banda Api Mountain is an active volcano and based on history has erupted 20 times over the past 400 years. The eruption of volcanic ash has covered most of Banda Naire Island in the east and Banda Big Island in the east and south of Banda Api Mountain. This study aims to determine the characteristics and classification types of soil formed from parent material deposited in recent volcanic ash in different topographic positions. The method used was free survey method through toposequence approach by determining the profile point based on a straight line (transect) while soil classification refers to the Soil Taxonomy System. The results of the study showed that the profile of the soil at the position of the foothills on the island of Banda Naire and the Banda Besar morphologically had Andisols properties (Typic Hapludands), but in generally the physical and chemical characteristics of each soil profile did not match with the Andisols requirements so that they were classified into the Inceptisols (Vitrandic Eutrudepts and Vitrandic Dystrudepts) (in the slope and foothills), while at the top of the hill were classified as Entisols (Typic Udipsamments).

Abstract
Technological developments have developed to monitor and map the activities of earth movements. One of the technologies developed for deformation monitoring is using Synthetic Aperture Radar Interferometry (InSAR) technology. InSAR is an effective method for measuring surface deformation with sub-centimeter precision. Image processing with this technique produces DEM. DEM is a 3D digital elevation model that shows the physical situation and topography of the earth which is defined as a digital model dimensions obtained from surface elevation using the selected interpolation method. The resulting DEM will be validated in the test area using the appropriate reference DEM. The case study area used is the Bandung area. Data processing with SNAP software where image recording on June 12, 2018 is used as a master image and June 23, 2018 as a slave image. The difference in angle of incidence between the two images is 420 where the master image is Tandem-X and slave image Terrasar-X. Acquisition scenario for DEM generation, several data sets obtained in different TerraSAR-X modes with different incidences of angle combinations in different of times. The baseline value of these two data is 322 meters. Stages of processing starting from coregistration, interferogram generation, goldstein phase filtering, phase unwrapping, phase to elevation and geocoding with DEM output for the Bandung region. From 24 field data points, 20 points are use as validation correction and 4 points as accuracy correction. The DEM generated from the TerraSAR-X corrected using regression corrected and shifting correction. DEM generation from shifting correction is better than regression corrected with absolut error 3,24 m and RMSE 5,52 m.

Abstract
Paddy growth monitoring is necessary conducted to ensure successful the harvest and production of paddy. The monitoring can be done by using satellite data, both optical and radar data, which can cover a large area and time observation frequency for seasonal crops, such as paddy. In tropical area, cloudy day usually happen, so that problems can’t be handle with optical data. Utilization of radar data that can penetrate the cloud condition can solve the problem, either as a complement of optical data or used alone to monitor the growth phase of paddy. The research was conducted to investigate the capability of Sentinel 1 SAR multi temporal data to detect the growth phase of paddy crop. The research was done in paddy fields belong to Sang Hyang Sri, Subang, West Java during the planting season of 2017. The results found that SAR data in dual polarization (HV, VV), and both combination can be used to detect paddy phase, such as early planting, vegetative, generative, and bare condition after harvesting.

Published: August 2019

Abstract
Sentinel satellite imagery using radar sensors for one particular area with the same orbit can be compared every 6 days and freely available to be downloaded. This advantage can be exploited to regularly identify land surface changes in a particular region. Paddy is a fast-growing crop with an approximately 120-day life cycle and specific growth stages related to phenological aspect, especially to changes in plant height. Hence, paddy growth stages can be monitored using this radar sentinel satellite with dual polarization data. Radar satellite is also cloud-free and therefore suitable for tropical regions such as Indonesia. This paper describes the results of a study on paddy field observation based on a correlation analysis between backscatter values of Sentinel-1A data with paddy growth stage observation. Sentinel-1A data from January 2018 to May 2018 were downloaded and processed using SNAP software. The study observed 5 stages: early vegetative (V1), late vegetative (V2), generative (G), Harvest (P), and Land Preparation (PL). An experiment was conducted by collocating the backscatter value of pixels at the location of the paddy growth stage observations, grouping and calculating the frequency for each class and then removing the class that had small frequency. These steps were carried out by way of iterations until the condition was above 5% of the threshold. Classification was performed based on range value obtained from the experiment to create paddy growth stage polygons. Correlation value between backscatter value σ0VH and paddy growth stage observation was 0.758. While correlation value between backscatter value σ0VV and paddy growth stage observation was 0.537.

Abstract
Precise Point Positioning (PPP) of a Global Navigation Satellite System (GNSS) can be considered as an alternative solution from the differential GNSS positioning technique. Recently, PPP technique takes the spotlight due to its low cost and large number of users. Initially dual frequency PPP technique was implemented using GPS only observations. Nowadays, it has started to combine GPS+GLONASS observations in order to improve the position accuracy and reduce the convergence time. The main objective of this research is to examine the performance ionospheric correction methods of the real time PPP using RTKLIB. RTKLIB is an open source program package for GNSS positioning. The overall results show that the ionosphere free LC method of real time RTKLIB PPP present better accuracy rather than Klobuchar model for all positioning modes.

Abstract
The Global Navigation Satellite System (GNSS), nowadays, is to be an important tool for determining positions and times on the real-time and post-processing applications. This study aims to assess the performance of the single frequency L1-GPS using low cost receivers. The performance will be evaluated by comparing with the geodetic L1+L2 GPS receiver to positioning performance. The low cost receivers used were Ublox NEO-M8T and Allystar HD9100. While, the dual frequency GPS TOPCON was used as reference receiver. The results show, RTK mode can improve the accuracy compare with single positioning up to centimetres. In this experiment, the Allystar HD9100 gives a better result than Ublox Neo M8T. However, the result discrepancies may be caused by the simple antenna splitter.

Abstract
Synthetic Aperture Radar (SAR) is newest remote sensing technology that is not affected by meteorological conditions. This technology is particularly suitable for use in tropical regions such as Indonesia. In tropical peatland, Indonesia becomes the most important countries for peat areas and carbon stocks. However, this tropical peatland forest had been disturbed by fires, and become a national issue and an international issue. In disaster mitigation, identifying the existence of tropical peatland are needed. But this information is very limited. Therefore, we analysed backscattering value of VV and VH polarisation, and estimated dielectric constant from a dual-polarisation Sentinel-1A in Siak Regency, Riau Province, Indonesia. We also measured dielectric constant at four several types of land use (namely, forest, oil palm, shrubs, and agriculture) along with two types of peat conditions. Results indicated that the dielectric constant decreases as the land use become dry. Results show that the profiles of dielectric constant derived from dual-pol Sentinel-1A images have a high similarity to the direct approach using GPR, with a degree of similarity of 87.24%. The averaged dielectric constants of peat are lower than the peat in subtropics area and ranges between 41 and 68.

The method of water change detection, direct cost based on replacement value of land was used for this assessment. Meanwhile, Bedono village was selected as study area. The results show a significant depreciation of 98 % of land value was occurred in the study area caused by inundation of sea water landward.
VS38 Identifies Myeloma Cells With Dim CD38 Expression and Plasma Cells Following Daratumumab Therapy, Which Interferes With CD38 Detection for 4 to 6 Months
Authors: Courville Elizabeth L , Yohe Sophia , Shivers Paula , Linden Michael A 
Published: August 2019

Abstract

Objectives
We report our institutional experience using VS38 to evaluate plasma cells by flow cytometry.

Methods
Flow cytometry data were reanalyzed to compare plasma cell percentages between the standard panel and VS38 panel. Natural killer (NK) and plasma cell CD38 median fluorescence intensity (MFI) values were calculated.

Results
Our cohort included 63 specimens from 38 patients. Twenty-six had received daratumumab (monoclonal anti-CD38 therapy) between less than 1 month and 17 months prior. For NK and plasma cells, CD38 MFI values were suppressed for 0 to 4 months and started to increase 4 to 6 months after last exposure. There was no significant difference in clonal plasma cell percentage calculated by the VS38 and standard panels; however, identification and quantification using the VS38 panel were easier.

Conclusions
VS38 is a viable alternative to bright CD38 to identify plasma cells and particularly helpful in myeloma cases with dim CD38 and after daratumumab. Daratumumab interference with CD38 identification persists 4 to 6 months after the last exposure.

Published: August 2019

Abstract

BACKGROUND
Limited research has examined the association of life-course socioeconomic status (SES) with hypertension prevalence and incidence in a large cohort of African Americans.

METHODS
Among 4,761 participants from the Jackson Heart Study (JHS), we examined the association of SES indicators with prevalent and incident hypertension. We used multivariable Poisson regression to estimate prevalence ratios (PR, 95% confidence interval—CI) of baseline (2000–2004) hypertension by adult (education, income, occupation, wealth) and childhood (mother’s education) SES. Cox proportional hazards regression was used to estimate hazard ratios (HR, 95% CI) of incident hypertension by adult and childhood SES (2005–2013; 7.21 median years of follow-up). We also examined the association of childhood-to-adult SES mobility (parent-to-adult education) with prevalent and incident hypertension. Model 1 adjusted for age and sex. Model 2 added waist circumference, behaviors (smoking, alcohol, physical activity, diet), and diabetes prevalence.

RESULTS
High (vs. low) adult SES measures were associated with a lower prevalence of hypertension, with the exception of having a college degree and upper-middle income (PR: 1.04, 95% CI: 1.01, 1.07; PR: 1.05, 95% CI: 1.01, 1.09, respectively). Higher childhood SES was associated with a lower prevalence and risk of hypertension (PR: 0.83, 95%: CI 0.75, 0.91; HR: 0.76, 95% CI: 0.65, 0.89, respectively). Upward mobility and consistent high SES (vs. consistent low SES) from childhood to adulthood was associated with a greater prevalence, but lower incidence of hypertension.

CONCLUSION
Efforts to prevent hypertension among African Americans should consider childhood and current SES status.

AbstractPelvic organ prolapse (POP) in lysyl oxidase like-1 knockout (Loxl1 KO) mice occurs primarily in parous mice and is rare in nulliparous mice. We determined the effect of Loxl1 deficiency on postpartum regulation of connective tissue metabolism genes and degradative enzyme activity in the vagina at 20 days gestation or 4 h, 48 h, 7 days, 15 days, 25 days, 7 weeks, or 12 weeks postpartum. Nulliparous Loxl1 KO and wildtype (WT) mice aged 11, 18, or 23 weeks were controls. Gene expression and enzyme activity were assessed using real-time quantitative reverse transcription PCR and fluorescein conjugated gelatin zymography, respectively. Parity, but not aging, had a significant influence on gene expression both with time postpartum and between KO and WT mice. Mmp2, Timp1, Timp2, Timp3, Timp4, Col1a1, Col3a1, Acta2, and Bmp1 were differentially expressed between KO and WT mice. Correlational analysis of gene-gene pairs revealed 10 significant differences between parous KO and WT groups, 5 of which were due to lack of co-expression of Bmp1 in KO mice. The overall enzyme activity that could be attributed to MMPs was significantly higher in WT compared to KO mice both 25 days and 12 weeks postpartum, and MMP activity was significantly lower 15 days and 25 days postpartum compared to KO nulliparous controls, but not WT. These findings suggest that Loxl1 deficiency combined with parity has a significant impact on postpartum regulation of connective tissue metabolism, particularly as it relates to co-expression of Bmp1 and altered proteolytic activity.
Fibrinogen in equine pregnancy as a mediator of cell adhesion, an epigenetic and functional investigation
Authors: Grant Danielle M , Macedo Alysson , Toms Derek , Klein Claudia 
Published: August 2019

AbstractPreimplantation equine embryos synthesize and secrete fibrinogen, which is a peculiar finding as fibrinogen synthesis almost exclusively occurs in the liver. This study investigated the hypothesis that conceptus-derived fibrinogen mediates cell adhesion during fixation. On day 21 of pregnancy, five integrin subunits, including ITGA5, ITGB1, ITGAV, and ITGB1, displayed significantly higher transcript abundance than on day 16 of pregnancy. Endometrial epithelial cells adhered to fibrinogen in an integrin-dependent manner in an in vitro cell adhesion assay. Bilaminar trophoblast and allantochorion expressed fibrinogen transcript, indicating that fibrinogen expression persists past fixation. Preimplantation-phase endometrium, conceptuses, and microcotyledonary tissue expressed components of the clotting cascade regulating fibrin homeostasis, leaving open the possibility that fibrinogen is converted to fibrin. Fibrinogen is likely to have functions beyond mediating cell adhesion, such trapping growth factors and triggering signaling cascades, and has remarkable parallels to the expression of fibrinogen by some tumors. The deposition of fibrinogen within tumor stroma is characteristic of breast carcinoma, and tumor-derived fibrinogen has been implicated in the metastatic potential of circulating tumor cells. DNA methylation of the fibrinogen locus in equine conceptuses was examined in comparison to liver and endometrium, and across the full gene cluster, was significantly higher for endometrium than liver and conceptus. DNA methylation of regulatory regions did not differ between liver and conceptus, and was significantly lower than in endometrium. These results, therefore, support the hypothesis of DNA methylation being a regulator of fibrinogen expression in the conceptus.
