Abstract. The “Advanced Land Observing Satellite-3” (ALOS-3, nicknamed “DAICHI-3”) is the next high-resolution optical mission as a successor of the optical mission by the Advanced Land Observing Satellite (ALOS, “DAICHI”) in Japan Aerospace Exploration Agency (JAXA), and will be launched in Japanese Fiscal Year 2020. ALOS-3 is now under developing the flight model. The major missions of ALOS-3 are (1) to contribute safe and secure social including provision for natural disasters, and (2) to create and update geospatial information in land and coastal areas. To achieve the missions, the “WIde-Swath and High-resolution optical imager” (WISH, as a tentative name) is mounted on ALOS-3, which consists of the high-resolution panchromatic- and multispectral-bands.This paper introduces the overview of ALOS-3’s mission and the calibration and validation plan at JAXA. The standard product is the system corrected data using the sensor models, which will be provided from the sensor development team. Therefore, the sensor calibration is directly affected to the accuracies of the standard product. In addition, the sensor model based the Rational Polynomial Coefficient will be contained with level 1B2 standard product that can be used to process an ortho rectification and three-dimensional measurement from ALOS-3 images. As the target accuracy of WISH’s standard products, the geometric accuracies are less than 5 m in horizontal without ground control point (GCP), and 1.25 m in horizontal and 2.5 m in vertical with GCPs (1 sigma), and the radiometric accuracy is ± 10 % as absolutely and ± 5 % as relatively for multispectral band.

Abstract:
Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), one of onboard sensors carried on the Advanced Land Observing Satellite (ALOS), was designed to generate worldwide topographic data with its optical stereoscopic observation. The sensor consists of three independent panchromatic radiometers for viewing forward, nadir, and backward in 2.5 m ground resolution producing a triplet stereoscopic image along its track. The sensor had observed huge amount of stereo images all over the world during the mission life of the satellite from 2006 through 2011. We have semi-automatically processed Digital Surface Model (DSM) data with the image archives in some limited areas. The height accuracy of the dataset was estimated at less than 5 m (rms) from the evaluation with ground control points (GCPs) or reference DSMs derived from the Light Detection and Ranging (LiDAR). Then, we decided to process the global DSM datasets from all available archives of PRISM stereo images by the end of March 2016. This paper briefly reports on the latest processing algorithms for the global DSM datasets as well as their preliminary results on some test sites. The accuracies and error characteristics of datasets are analyzed and discussed on various fields by the comparison with existing global datasets such as Ice, Cloud, and land Elevation Satellite (ICESat) data and Shuttle Radar Topography Mission (SRTM) data, as well as the GCPs and the reference airborne LiDAR/DSM.

Abstract:
Ausonius was a latin poet, born in Burdigala (Bordeaux), who, <em>inter alios</em>, composed the poetic work entitled "Caesares" between 379-383 A.D. This collection is an exposition of the lives of Roman emperors in verse (in hexameter and elegiac couplets). The collection is not complete. The work stops suddenly at the incomplete quatrain of Elagabalus. In this paper the author deals with the literary genre of the collection, the style of the poem, while he also attempts to trace the texts the poet used (Suetonius, Tacitus, the so[called <em>Kaisergeschichte</em>, Marius Maximus etc.). Finally he refers to the proposals concerning the missing part of the collection as put forth by various scholars in recent years.

<p><strong>Abstract.</strong> The Advanced Land Observing Satellite-2 (ALOS-2) was launched on May 24, 2014, and it is operating very well in space more than 4.5 years. The designed mission life is five years as nominal operational phase and the target is over seven years since launch the satellite. The mission objectives of ALOS-2 are 1) disaster monitoring, 2) national land and infrastructure information, 3) cultivated area monitoring, and 4) global forest monitoring. To achieve the objectives, ALOS-2 carries on the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2), which is an active microwave radar using the 1.2 GHz frequency band and observes in day and night times even in bad weather conditions as successor PALSAR instrument onboard ALOS satellite operated from 2006 to 2011. PALSAR-2 instrument has several enhanced features from PALSAR e.g. finer spatial resolution, spotlight observing mode, dual-polarisation ScanSAR. This paper summarises an introduction of typical data analysis results for monitoring natural disasters by ALOS-2 during the operational phase. As the response natural disasters, more than 400 times of the emergency observations have been conducted to identify damages caused by volcanic activities, earthquakes, flooding etc. happened in Japan and the World.</p>

Abstract:
Mt. Bromo is geographically located in eastern of Java Island at 112°57'30'' longitude and 7°56' latitude, with a large area of caldera ~10 Km2. The land over the volcano is a perfect area for farming, one of the important factor affects the level of soil fertility is the most mineral rich soils. Volcanic activities at Mt. Bromo has been recorded in 1775 which characterized by small eruptions with cycles ranging from one to five years. Regarding this evidence, we tried to investigate the surface changes over the Mt. Bromo by using Time-Series InSAR with TimeFun algorithm. TimeFun is an extension of SBAS to allow incorporating various functions such as seasonal oscillations, polynomials, and step functions as generally it estimates DEM errors as well and allows missing observation. The maximum allowed baseline value is defined and used to constrain the interferogram pair by selecting manual after differential InSAR processing in single face working. The proposed analysis is based on 27 SAR data sets acquired by the ALOS/PALSAR sensors during the 2007–2017 time interval. The result shows us deformation occurred up to ~10 cm at summit of Mt. Bromo during the eruption period. Time-series monitoring of surface deformation to infer volume changes, geometries and locations of sources of deformation involved in the future eruption

Abstract. In 2016 we first completed the global data processing of digital surface models (DSMs) by using the whole archives of stereo imageries derived from the Panchromatic Remote sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS). The dataset was freely released to the public in 30 m grid spacing as the ‘ALOS World 3D - 30m (AW3D30)’, which was generated from its original version processed in 5 m or 2.5 m grid spacing. The dataset has been updated since then to improve the absolute/relative height accuracies with additional calibrations. However the most significant update that should be applied for improving the data usability is the filling of void areas, which correspond to approx. 10% of global coverage, mostly due to cloud covers. In this paper we introduce the updates of AW3D30 filling the voids with other open-access DSMs such as Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM), Advanced Spaceborne Thermal Emission and Reflection Radiometer Global DEM (ASTER GDEM), ArcticDEM, etc., through inter-comparisons among these datasets.

Abstract:
ABSTRACT The European Space Agency (ESA) Gaia mission has enabled the remarkable discovery that a large fraction of the stars near the solar neighbourhood are debris from a single in-falling system, the so-called Gaia-Sausage-Enceladus (GSE). This discovery provides astronomers for the first time with a large cohort of easily observable, unevolved stars that formed in a single extragalactic environment. Here we use these stars to investigate the ‘Spite plateau’ – the near-constant lithium abundance observed in unevolved metal-poor stars across a wide range of metallicities (−3 &lt; [Fe/H] &lt; −1). Our aim is to test whether individual galaxies could have different Spite plateaus – e.g. the interstellar medium could be more depleted in lithium in a lower galactic mass system due to it having a smaller reservoir of gas. We identified 93 GSE dwarf stars observed and analysed by the GALactic Archaeology with HERMES (GALAH) survey as part of its Data Release 3 (DR3). Orbital actions were used to select samples of GSE stars, and comparison samples of halo and disc stars. We find that the GSE stars show the same lithium abundance as other likely accreted stars and in situ Milky Way stars. Formation environment leaves no imprint on lithium abundances. This result fits within the growing consensus that the Spite plateau, and more generally the ‘cosmological lithium problem’ – the observed discrepancy between the amount of lithium in warm, metal-poor dwarf stars in our Galaxy, and the amount of lithium predicted to have been produced by big bang nucleosynthesis – is the result of lithium depletion processes within stars.

In dem Maße, in dem sich seit dem europäischen achtzehnten Jahrhundert die PostSende-Verhältnisse dramatisch verbessern, verblasst die Überzeugungskraft des religiösen Sendungsbewusstseins. Verwunderlich ist das nicht. Von einem göttlichen Anruf, einem Kerygma erreicht zu werden, soll, ja muss eine exquisite Ausnahme von den Regelmäßigkeiten des Alltagslebens sein. Viele sind berufen, aber nur wenige sind auserwählt (Matthäus 22,14). In nur einigermaßen aufgeklärten Zeiten ist die Frage nach der Verlässlichkeit der himmlischen Postund Sendeverhältnisse nicht zu unterdrücken. Jeder kann jedem (zunehmend ohne Angst um Leib und Leben) bestreiten, der rechte Adressat göttlicher Sendungen zu sein. Intersubjektiv verbindliche Sendeverhältnisse zwischen Himmel und Erde gibt es nicht; diese höhere Trivialität wird seit 1750 aussagbar und aufschreibbar. Komplementär dazu steigt – trotz enormer Komplexitätsgewinne – die Kontrollierbarkeit irdischer Sendeverhältnisse. </br></br>To the extent in which postal 'sending,' the successful delivery of messages, dramatically improves since the European eighteenth century, the persuasiveness of the religious sense of mission or 'sending' is fading. This is not surprising. To be reached by a divine call, by a Kerygma, should, indeed must be an exquisite exception of the regularities of everyday life. Many are called but few are chosen (Matthew 22:14). In somewhat enlightened times, the question of the reliability of heavenly sendings cannot be suppressed anymore. Anyone can deny anyone to be the truthful addressee of divine sendings. There are no intersubjectively binding states of transmission between heaven and earth: this higher triviality is predicable and writable since 1750. Complementary to this development, the controllability of terrestrial sendings increases– despite enormous gains in complexity.

Abstract:
It may seem redundant to address Sport as a development trigger but, sometimes, redundancy is necessary for someone to be heard.The commanding voices of Philosophy in the XXth century take sciences as trivial, by expressing the notion that Science has nothing to do with the ontological and metaphysical statutes of men.What is at stake is too much important, as the attack is not aimed at Sciences, organizations and institutions, nor at the people, but rather against Reason itself.We found ourselves immersed in irrationalities and superstitions in the most primitive form of belief. Worldwide there are three times more astrologists than there are physics. In Portugal, also in Sport, there are numberless stand-coaches and pseudo-writers, which all speak and write about exercise and appear as public opinion makers, stating banalities that discredit Sport and its professionals.In western science, what is axiomatic is not merely the concept of progress, but rather the concept of constant and unlimited progress. And we take for granted this lack of limits… Indeed, it seems …… In fact, it is a deeply enigmatic assumption, taking into account the metaphysical meaning of the term. And it is from these assumptions that we must analyse the role of Sport and Exercise. Biological life may be increased in duration, but death will come: and the challenge is therefore the quality of an extended life. In Sport and exercise, progress has more than a technical relevance, it has an ontological relevance: the enhancement of a life cycle.Sport is, therefore, an immeasurable asset and holds opportunity to induce peace and be a promoter of several social causes.Sport is one of the possible, perhaps the main, cultural objectification and historical form of movement. This is only possible by valuing the fundamental character of the body in motion, because it is upon it that the sports body is installed and merges. Even giving it a fundamental meaning, it has not yet found its value due to the failure in the evaluation of its return, whether educational, social, health, economic or structural.The importance of Sport and its institutions cannot be measured, as much as some state so, by performance indicators in an international setting (this leads to unfair, unproportioned comparisons among sports with different density and international coverage).A message that, unfortunately, has passed to general society, involving risks to lower even more the national sport involvement is: resources must be mainly focused in the few sports with international merit. With time, this will end up in an overall failure of national Sport, and subsequently a progressive underfinancing of the Sport will appear.Every organization that deal with Sport cannot deviate from what is its main mission, to organize, promote and spread the Sport for a permanent and constant demonstration that what is done and how it’s done fully respect the high public interest and, ultimately, serves the people.This role is also that of Science.

Abstract. Land subsidence affects highly developed urban areas in central Mexico, where inhabitants rely on groundwater for about 60 % of water supply and most of the cities are located in volcanic valleys filled with fine and coarse grained sediments. Compaction associated to groundwater depletion in areas with subsoil contacts sediments-rock have caused differential subsidence, ground fracturing and eventually the reactivation of pre-existing faults, depending on the local geological setting. Remote sensing monitoring methods of land deformation have proved to be useful tools to assess this geological hazard for urban planning. We used L-band ScanSAR data from the ALOS-2 PALSAR-2 mission to produce a regional land subsidence map over an area of about 350 km × 350 km over central Mexico. Our results indicate with a remarkable spatial coverage widespread land subsidence over the major cities, which is ranging from more than 30 cm yr−1 in Mexico City to 5–10 cm yr−1 in other locations.

Abstract:
Topographical information is fundamental to many geo-spatial related information and applications on Earth. Remote sensing satellites have the advantage in such fields because they are capable of global observation and repeatedly. Several satellite-based digital elevation datasets were provided to examine global terrains with medium resolutions e.g. the Shuttle Radar Topography Mission (SRTM), the global digital elevation model by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER GDEM). A new global digital surface model (DSM) dataset using the archived data of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”) has been completed on March 2016 by Japan Aerospace Exploration Agency (JAXA) collaborating with NTT DATA Corp. and Remote Sensing Technology Center, Japan.

Abstract:
Topographical information is fundamental to many geo-spatial related information and applications on Earth. Remote sensing satellites have the advantage in such fields because they are capable of global observation and repeatedly. Several satellite-based digital elevation datasets were provided to examine global terrains with medium resolutions e.g. the Shuttle Radar Topography Mission (SRTM), the global digital elevation model by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER GDEM). A new global digital surface model (DSM) dataset using the archived data of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard the Advanced Land Observing Satellite (ALOS, nicknamed “Daichi”) has been completed on March 2016 by Japan Aerospace Exploration Agency (JAXA) collaborating with NTT DATA Corp. and Remote Sensing Technology Center, Japan. This project is called “ALOS World 3D” (AW3D), and its dataset consists of the global DSM dataset with 0.15 arcsec. pixel spacing (approx. 5&thinsp;m mesh) and ortho-rectified PRISM image with 2.5&thinsp;m resolution. JAXA is also processing the global DSM with 1&thinsp;arcsec. spacing (approx. 30&thinsp;m mesh) based on the AW3D DSM dataset, and partially releasing it free of charge, which calls “ALOS World 3D 30&thinsp;m mesh” (AW3D30). The global AW3D30 dataset will be released on May 2016. This paper describes the processing status, a preliminary validation result of the AW3D30 DSM dataset, and its public release status. As a summary of the preliminary validation of AW3D30 DSM, 4.40&thinsp;m (RMSE) of the height accuracy of the dataset was confirmed using 5,121 independent check points distributed in the world.

Abstract:
The precious historical collection of fibres in Meise Botanic Garden, with over 500 specimens in old hand-blown glass jars, was rehabilitated in 2017. Most of the specimens date back to the second half of the 19th century, a period of technological revolution. The rehabilitation retraces the industrious search for every possible raw material provided by nature at that time. The result is astonishing, not only regarding the origin and quality of the preserved material, its label information and its accompanying manuscripts, but also because of the extremely wide range of fibre species and their processing. Noted collectors enriching our collections were, inter alios, the Josephite Brother Bernardin of Melle (Belgium), Carl von Martius and his brother Theodor Martius of Erlangen (Germany) and Henri Van Heurck of Antwerp (Belgium). Famous museums and botanic gardens such as the Museum of French Colonies in Paris (France) and the Experimental Garden in Eala (Democratic Republic of the Congo DRC) were also important suppliers. Samples originate from all over the world with strong representation from India, the DRC and Brazil. The nature of the fibres in the collection is very diverse and ranges from stem, bark and leaf fibres to husk fibres and seed hairs. Some of them have been processed into bundles and braids, beaten bark, spun thread and twined rope, as well as rough or organza-like fabrics. Even plant pith, pulp and paper are included, next to silkworm silk and mineral tremolite (a form of asbestos). Not only are familiar plant fibres such as cotton, sisal, ramie, coir, flax and jute present, but also Congo jute, Cuban bast, lacebark, piassava, esparto, fern wool, fibres of linden, sunflower, banana and pineapple, next to different types of paper and bark cloth. More than a hundred genera appear. Dominant families in terms of specimen numbers are Malvaceae (including Tiliaceae), Liliaceae (including Agavaceae), Palmae, Urticaceae, Bombacaceae, Musaceae and Gramineae. This upgraded collection exhibits an unexpected data diversity and consequently offers multitudinous possibilities for innovative research. One of our mission statements is undoubtedly: safeguarding historical collections for the future.

Abstract:
Monitoring the temporal changes of forests is important for sustainable forest management. In this study, we investigated the potential of using multi-temporal synthetic aperture radar (SAR) images for mapping annual change in forest cover at a national scale. We assessed the robustness of using multi-temporal Phased Array L-band Synthetic Aperture Radar-2/Scanning Synthetic Aperture Radar (PALSAR-2/ScanSAR) mosaic images for forest mapping by comparison with single-temporal PALSAR-2 mosaic images for three test sites in North, Central, and Southern Vietnam. We then used a combination of multi-temporal PALSAR-2/ScanSAR images, multi-temporal Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) images, and Shuttle Radar Topography Mission (SRTM) images to map annual forest cover for mainland Vietnam during 2015–2018. Average overall accuracies of our forest/non-forest (FNF) maps (86.6% ± 3.1%) were greater than recent maps of Japan Aerospace Exploration Agency (JAXA, (77.5% ± 3.2%)) and European Space Agency (ESA, (85.4% ± 1.6%)). Our estimates of mainland Vietnam’s forest area were close to that of the Vietnamese government. A comparison of the spatial distribution of forest estimated from JAXA and ESA FNF maps showed that our FNF map in 2015 agreed relatively well with the ESA map, with 77% of pixels being consistent. This study demonstrates the merit of using multi-temporal PALSAR-2/ScanSAR images for annual forest mapping at a national scale.

Abstract:
Analysis of synthetic aperture radar (SAR) images in L-band of short-period internal waves (IWs), and classification of their radar signatures is presented by means of a polarimetric data set from ALOS-PALSAR mission. We choose the polarimetric feature named standard deviation(std) of the co-polarized phase difference (CPD) to identify fundamental differences in SAR signatures of internal waves, and divided them into three different classes, according to their backscattered modulation depths and morphology as well as the std CPD, namely: double-signed, single-negative, and single-positive signatures, for IW normalized image transects that display, respectively, signatures in the form of bright/dark, dark, and bright bands that correspond to positive/negative, negative, or positive variations of radar backscatter. These radar power types of signatures have a counterpart in the std CPD normalized transects, and in this paper we discuss those correlations and decorrelations. We focus in the single-negative type of signature, that is dark bands on gray background, and show that the std CPD is greatly enhanced over the troughs and rear slopes of those IWs. It is suggested that such behavior is consistent with the presence of surface slicks owing to enhanced surfactant concentration. Furthermore, those single-negative SAR signatures appear at locations where and when biological productivity is enhanced. It is found that the modulation depths associated to the std CPD is higher than the one associated to the HH-polarized radar backscatter for single-negative signatures propagating in the range direction, while the reverse occurs for the other types of signatures.

Abstract:
Forest canopy height is a basic metric characterizing forest growth and carbon sink capacity. Based on full-polarized Advanced Land Observing Satellite/Phased Array type L-band Synthetic Aperture Radar (ALOS/PALSAR) data, this study used Polarimetric Interferometric Synthetic Aperture Radar (PolInSAR) technology to estimate forest canopy height. In total the four methods of differential DEM (digital elevation model) algorithm, coherent amplitude algorithm, coherent phase-amplitude algorithm and three-stage random volume over ground algorithm (RVoG_3) were proposed to obtain canopy height and their accuracy was compared in consideration of the impacts of coherence coefficient and range slope levels. The influence of the statistical window size on the coherence coefficient was analyzed to improve the estimation accuracy. On the basis of traditional algorithms, time decoherence was performed on ALOS/PALSAR data by introducing the change rate of Landsat NDVI (Normalized Difference Vegetation Index). The slope in range direction was calculated based on SRTM (Shuttle Radar Topography Mission) DEM data and then introduced into the s-RVoG (sloped-Random Volume over Ground) model to optimize the canopy height estimation model and improve the accuracy. The results indicated that the differential DEM algorithm underestimated the canopy height significantly, while the coherent amplitude algorithm overestimated the canopy height. After removing the systematic coherence, the overestimation of the RVoG_3 model was restrained, and the absolute error decreased from 23.68 m to 4.86 m. With further time decoherence, the determination coefficient increased to 0.2439. With the introduction of range slope, the s-RVoG model shows improvement compared to the RVoG model. Our results will provide a reference for the appropriate algorithm selection and optimization for forest canopy height estimation using full-polarized L-band synthetic aperture radar (SAR) data for forest ecosystem monitoring and management.

Abstract:
Abstract Background The AASLD HBV management guidelines were updated in 2018 to include new recommendations. Patient variables that inform HBV treatment candidacy and treatment selection are complex and interconnected. To aid healthcare practitioners (HCPs) in aligning management decisions with practice guidance, we developed a Web- and app-based decision support tool, Hep B Consult. Methods The tool enables users to specify a guideline (AASLD, EASL, or APASL) and prompts them to enter patient variables: HBV DNA/ALT levels, liver fibrosis, extrahepatic manifestations, family history of HCC or cirrhosis, pregnancy status, coinfection, and comorbidities. Users select their intended approach for the case, after which the tool displays guideline recommendations specific to that case. Cases entered from January 2019-April 2020 by users who specified AASLD guidance (N = 7106) were assessed. Results For 32.3% of cases, the user selected “unknown” for a variable necessary to reach a guideline recommendation (Fig 1). The information most often missing was the level of fibrosis/inflammation (unknown in 16.3% of cases). HCPs’ intended management approach matched the guidelines in 61.3% of cases for which a guideline recommendation was possible (Fig 2; n = 3742). Cases in which the HCP chose to monitor when treatment was indicated (11.6%) and those in which the HCP was unsure (12.2%) represented the largest discrepancies. Certain types of cases demonstrated higher discordance (Fig. 2). The intended approach did not match the guidelines for 49.2% of immune-tolerant cases (n = 128). We also identified patterns important for patient health. In 20.0% of cases with compensated cirrhosis or moderate/severe inflammation or fibrosis (n = 345) and 12.5% of cases with decompensated cirrhosis (n = 72), the HCP intended to monitor although treatment was indicated. Figure 1. Recommendation outcomes of cases entered for AASLD guidance. Figure 2. Inconsistencies between HCPs intended management practices and AASLD guidelines. Conclusion This tool highlights important knowledge gaps in information needed to make appropriate HBV management decisions, particularly in the setting of cirrhosis. It also demonstrates differences between HCPs’ approaches and the AASLD guideline recommendations. Of cases in which the HCPs’ intention were inconsistent with guidelines, 52.1% indicated that they planned to change their approach after being provided the recommendation by the tool (Fig 3).

Abstract:
Abstract Introduction: The management of hematologic malignancy-associated VTEin patients with moderate to severe thrombocytopenia is unclear. Clinical trials of anticoagulants in VTE exclude such patients, hence do not inform the risk of bleeding or clot progression. Consensus-based guidelines recommend case-by-case consideration for either platelet transfusion to maintain platelet count >50,000/µL and therapeutic anticoagulation, or 50% dose reduction in LMWH (J Thromb Haemost. 2013 Jan;11(1):56-70.; Curr Oncol. 2015 Apr;22(2):144-55). At our institution, our approach is to use prophylactic dose LMWH for patients with platelet count ≤50,000/µL. Method: This is a single-center retrospective study of 128 adult patients with hematologic malignancies, who were diagnosed with VTE. Patients were identified from hospital research database. The diagnoses were verified after the review of medical records. The platelet count was assessed during the period of anticoagulation for VTE. The outcomes of patients with significant thrombocytopenia (≤50,000/µL) was compared with those without. Bleeding and clot recurrence was assessed until the last follow-up (median of >1 month). Fisher's Exact test was used to test the association between two categorical variables, and Analysis of Variance (ANOVA) was used to test the association between a continuous variable and a categorical variable. Results: Characteristics of the study population were as follows: 51% male, 47% non-Hodgkin lymphoma, 20% acute leukemia/myelodysplastic syndrome, 40% status-post hematopoietic stem cell transplant, 9% with creatinine >2 mg/dl, 36% with pulmonary embolism and 28% with catheter-related VTE. Forty six patients (36%) had a platelet count ≤50,000/µL during a period of time of perceived need for new or continued anticoagulation. The median nadir platelet count in those with significant thrombocytopenia was 9000/µL( range 2000-45,000/µL) versus 166,000/µL (range 50,000-389,000/µL) in those without (p<0.001). The median duration of significant thrombocytopenia in the first group was 10 days (range 1-68 days). Therapy during the period of significant thrombocytopenia included prophylactic dosing of LMWH (46%), therapeutic dose of LMWH or heparin (30%), warfarin (2%), inferior vena cava filter (2%) and observation (17%). Patients without thrombocytopenia were managed with the standard of care therapy. At last follow-up, the risk of bleeding (p=0.65) and clot progression (p=0.81) were similar in the two groups (Table 1). Conclusion: Within the limits of this retrospective study, cautious use of dose-adjusted LMWH in thrombocytopenic patients with hematologic malignancy-associated VTE may be safe. A prospective trial of prophylactic dose LMWH in patients with VTE during thrombocytopenia is required to confirm the safety and, to some extent, efficacy of such an approach. Table 1.

Abstract:
Abstract We have demonstrated that long-term culture initiating cells (LTC-IC) are maintained in a stroma noncontact (SNC) culture where progenitors are separated from stroma by a microporous membrane and LTC-IC can proliferate if the culture is supplemented with interleukin-3 (IL-3) and macrophage inflammatory protein-1α (MIP-1α). We hypothesize that the same conditions, which result in LTC-IC proliferation, may also maintain lymphoid progenitors. Natural killer (NK) cells are of lymphoid lineage and a stromal-based culture can induce CD34+/Lin−/DR−cells to differentiate along the NK cell lineage. We developed a three-step switch culture assay that was required to demonstrate the persistence of NK progenitors in CD34+/Lin−/DR− cells assayed in SNC cultures supplemented with IL-3 and MIP-1α. When CD34+/Lin−/DR− progeny from the SNC culture were plated sequentially into “NK cell progenitor switch” conditions (contact with stromal ligands, hydrocortisone-containing long-term culture medium, IL-2, IL-7, and stem cell factor [SCF]) followed by “NK cell differentiation” conditions (contact with stromal ligands, human serum, no hydrocortisone, and IL-2), significant numbers of CD56+/CD3− NK resulted, which exhibited cytotoxic activity against K562 targets. All steps are required because a switch from SNC cultures with IL-3 and MIP-1α directly to “NK cell differentiation” conditions failed to yield NK cells suggesting that critical step(s) in lymphoid commitment were missing. Additional experiments showed that CD34+/CD33− cells present after SNC cultures with IL-3 and MIP-1α, which contained up to 30% LTC-IC, are capable of NK outgrowth using the three-step switch culture. Limiting dilution analysis from these experiments showed a cloning frequency within the cultured CD34+/CD33− population similar to fresh sorted CD34+/Lin−/DR− cells. However, after addition of FLT-3 ligand, the frequency of primitive progenitors able to develop along the NK lineage increased 10-fold. In conclusion, culture of primitive adult marrow progenitors ex vivo in stroma-derived soluble factors, MIP-1α, and IL-3 maintains both very primitive myeloid (LTC-IC) and lymphoid (NK) progenitors and suggests that these conditions may support expansion of human hematopoietic stem cells. Addition of FLT-3 ligand to IL-2, IL-7 SCF, and stromal factors are important in early stages of NK development.

Abstract Abstract 1545 Introduction: The diagnosis of peripheral T-cell lymphoma (PTCL) is difficult and accurate diagnosis and subclassification relies on correlating histologic, immunophenotypic, molecular genetic, and clinical data. Evidence-based guidelines for the appropriate diagnostic work-up of PTCL are lacking. The objective of this study was to evaluate a large series of PTCLs by experienced hematopathologists with a tiered approach to immunohistochemistry (IHC) and molecular genetic characterization to document overall diagnostic accuracy and clinical relevance using this approach. Methods: 7 experienced hematopathologists from 5 institutions reviewed 374 cases of peripheral T and NK cell lymphomas (referred to collectively as PTCL). 6 cases of cutaneous T-cell lymphoma were excluded after final review in addition to 29 non-PTCL cases submitted as control cases to mimic diagnostic practice during the review. Cases received tier 0, 1 and 2 diagnoses by 3 independent pathologists, based on review of hematoxylin and eosin (HE) stain with basic demographic data, panel 1 IHC (CD3, CD5, CD10, CD20, CD21, CD30, CD45, PAX5), and panel 2 IHC (CD2, CD4, CD7, CD8, CD23, PD1, CD56, EBER, ALK, TIA1, TCRg, TCRbF1), respectively. A tier 2b diagnosis was then rendered after gene rearrangement data were available. A final consensus diagnosis was rendered after discussion of each case by the 3 reviewers with all available clinical data. Overall survival (OS) was assessed using Kaplan-Meier (KM) curves and Cox proportional hazards models. Results: 1122 individual diagnoses leading to 339 final consensus PTCL diagnoses were rendered. 341 (91%) cases had complete phenotypic data and 241 had gene rearrangement data. There was no bias of missing data according to final diagnosis subtype. Reviewer diagnoses using specific WHO subclassification were 16.3%, 36.9%, 82.7%, and 85.9% for tier 0, 1, 2, and 2b, demonstrating a significant increase in diagnostic certainty after a complete IHC panel. Gene rearrangement only contributed to a change in diagnosis in 51/650 (8%) individual reviews. Across all 374 cases, a small number of cases (n=28, 7.5%) showed no agreement among the 3 independent reviewers after tier 2b and required debate. These generally represented refinement of the subclassification of a PTCL. The most common disagreements were between PTCL, not otherwise specified (nos) vs. unclassifiable T-cell lymphoma, and PTCL, nos vs. angioimmunoblastic T-cell lymphoma (AITL). Currently, OS data was available in 198 cases and 52% have died (median age follow-up of 15 months for those still alive, range 0–160 mo). Figure 1 shows the KM survival curves for types with more than 10 cases. Of note, unclassifiable PTCL cases had poor OS, comparable to PTCL nos; a trend was seen for CD30+ ALK- ALCL to have a longer OS compared to PTCL nos (HR=0.5, 95% CI: 0.21–1.19, P=.09). EBER positivity in tumor cells was associated with poor OS in the cohort of all PTCL patients (HR=2.32, 95% CI: 1.28–4.23, p=0.006, Figure 2); the association was similar when nasal NK/T-cell lymphoma cases were excluded (HR=2.50, 95% CI: 1.00–6.26, p=0.05). Trends for poor prognosis were also seen for TIA-1 expression in PTCL, nos (HR=1.9, 95% CI 0.91–3.96, P=.09) and PD1 expression in AITL (HR=6.25, 95% CI 0.85–46.09, P=.07). Clinical data collection is still ongoing and will be updated. Conclusions: We demonstrate the diagnostic accuracy among experienced hematopathologists of a defined IHC panel, showing an overall ability to reach consensus diagnosis of 93% in PTCL cases. The resulting consensus diagnostic subtypes showed expected outcomes relative to other large series of PTCLs, and EBER positivity is a poor prognostic marker among T and NK cell lymphomas. A tiered approach to IHC is recommended when a PTCL is under differential diagnostic consideration since the first tier can often resolve the main question of whether a lesion is reactive or lymphoma. This can lead to more efficient use of the expanded tier 2 panel that will enable diagnosis and specific subclassification of PTCL. Gene rearrangement studies are not required in the great majority of cases. This evidence-based approach to the diagnosis of PTCL should inform practicing pathologists, clinical trial design, and policy makers regarding required ancillary studies in this group of diseases.

Abstract:
Digital Elevation Model (DEM) is a source to produce contour map, slope, and aspect information, which is needed for other information such as disaster and water resources management. DEM can be generated by several methods. One of them is parallax calculations from stereoscopic data of optical sensor. Panchromatic Remote-Sensing Instrument for Stereo Mapping (PRISM) sensor from Advanced LAnd Observation Satellite (ALOS) satellite and advance space borne Thermal Emission and Reflection Radiometer (ASTER) sensor from Terra Satellite is Japanese optical satellite sensor which have abilityto produce stereoscopic data. This study showed DEM generations from PRISM (2.5 m spatial resolution) and ASTER (15m spatial resolution) stereoscopic data using image matching and collinear model based on Orthobase-pro software. The Generated DEM from each sensor was compared to the DEM from Shuttle Radar Topography Mission (SRTM) X-C band with 30 m spatial resolution. The dependent on the pixel size from the DEM produced were also discussed. The result showed that both DEMs have similiar elevation and distribution pattern to the referenced DEM, but DEM for PRISM had higher relative accuracy (RMSE is 6.5 m) and Smoother pattern comparing to DEM from ASTER (RMSE is 10.2 m) Keyword : ASTER, DEM, PRISM, SRTM, Stereoscopic satellite data

Abstract:
Abstract. Digital Elevation Model (DEM) was generated from Advanced LandObservation Satellite - The Panchromatic Remote-Sensing Instrument for Stereo Mapping(ALOS PRISM) stereo data using image matching and collinear correlation based on LeicaPhotogrametry Suite (LPS) software. The process needs three dimension of Ground ControlPoint (GCP) or Control Point (CP) XYZ as input data for collinear correlation to determineexterior orientation coefficient. The main problem of the DEM generation is the difficultyto obtain the accurate field measurement GCP in many areas. Therefore, another alternativeCP sources are needed. The aim of this research was to study the possibility of (IKONOS)image and Shuttle Radar Topography Mission (SRTM) X-C band to be used as CPreference for ALOS PRISM DEM generation. The study area was Sragen and Bandungregion. The DEM of each study area was generated using 2 methods: generated using fieldmeasurement GCPs taken by differential GPS and generated using CPs from IKONOSimage (XY coordinat) and SRTM for (Z elevation). The generated DEMs were compared.The accuracy of both DEMs were evaluated using another field measurement GCPs. Theresult showed that the generated DEM using CPs from IKONOS and SRTM X-C hadrelatively same height pattern and height distribution along transect line with the DEMusing GCPs. The absolute accuracy of the DEM using CPs was about 60% - 80% lessaccuracy comparing to the DEM using GCPs. This research showed that IKONOS imageand SRTM X-C band can be considered as good alternative CP source to generate highaccuracy DEM from ALOS PRISM stereo data.

Abstract:
In today's economy, credit card (CC) plays a major role. It is an inevitable part of a household, business & global business. While using CCs can offer huge advantages if used cautiously and safely, significant credit & financial damage can be incurred by fraudulent activity. Several methods to deal with the rising credit card fraud (CCF) have been suggested. Both such strategies, though, are meant to prevent CCFs; each of them has its own drawbacks, benefits, and functions. CCF has become a significant global concern because of the huge growth of e-commerce and the proliferation of payment online. Machine learning (ML) algo as a data mining technology (DM) was recently very involved in the detection of CCF. There are however several challenges, including the absence of publicly available data sets, high unbalanced size, and different confusing behavior. In this paper, we discuss the state of the art in credit card fraud detection (CCFD), dataset and assessment standards after analyzing issues with the CCFD. Dataset is publicly available in the CCFD data set used in experiments. Here, we compare two ML algos of performance: Logistic Regression (LR) and XGBoost in detecting CCF Transactions Real Life Data. XGBoosthas an inherent ability to handle missing values. When XGBoost encounters node at lost value, it tries to split left & right hands & learn all ways to the highest loss. This is when the test runs on the data. The experimental results show an effective use of the XGBoost classifier. Technique of performance is widely accepted metric based on exclusion: accuracy & recall. Also, the comparison between both approaches displayed based on the ROC curve
