Abstract
Track Holder refers to the efforts of redesigning spoor holder device that has been sold in foreign market. Looking at the use of hammer that causes movement and damage on both the holder and the track, the manufacture of the track holder is intended to attain precise spoor width (1, 067 mm) without causing any damage to the rail components under affordable budget. The manufacture of the track holder should go through three stages namely preparation, assembly/production and finishing. The track holder device that has been designed consists of two motor systems namely the manual system and the electric system. The dynamo that has been installed is Wiper Colt 130 W and 12 V 3 A Battery. Then, the weight per unit of the device is 4 kg while the length of the device is 1.30 m. The track holder device is able to sustain weight up to 3, 282 kg. The prototype of the device was tested on the rail track with three devices and 2-bearing gap. The results of the test show that the track holder device is able to shift the rail track when the fastenings from all of the six bearings are uninstalled. The cost of manual track holder manufacture is IDR 1, 229, 000.00 while the cost of electric track holder manufacture is IDR 405, 350.00. In other words, the track holder device is prominent in terms of technology and price but the use of electric track holder device should be evaluated further on the use of ratio gear and dynamo.

Abstract
Currently, the higher education curriculum has developed two systems, namely the block-based curriculum in the field of medicine and the semester credit-based curriculum. The block-based curriculum is currently applied in medical schools while the semester credit-based curriculum is applied in non-medical faculties. The presence of these two curriculum systems raises problems in the management of academic information systems. One of the problems that occur is that the existing information system has not been able to manage the block curriculum and semester credit simultaneously in one system. So that this causes the academic information system unable to manage the implementation of assessments on the block-based curriculum. This paper proposes a new model in the design of academic information systems that are able to integrate the needs of block-based curriculum and credit. The method used to solve this problem is an object-oriented approach using class diagrams as a model to describe the structure of academic information systems. The results of the development of the new model show that the structure of the block-based curriculum is a general form (generalization) of semester-based credit. Therefore the implementation of the two curriculums can use a similar model class structure to be more efficient and easier to maintain information system software in the future.

Abstract
The electrical energy has been dependent on fossil fuels, but the availability of fossil energy is running low with increasing electricity demand in society. Therefore a lot of research is done on renewable energy sources, one of which is solar energy. Solar energy can be applied to home scale DC microgrid systems. In the DC microgrid system the independent source of energy for the supply of loads comes from two sources, namely DC bus and 120 volt battery. To combine these two energy sources, a bidirectional converter is needed which will regulate power flow and electricity storage. In this system the battery can become a burden and can be a source of energy in the same series. Bidirectional converters can work in two directions, namely charging mode and discharging mode. The type of converter used in this bidirectional converter is SEPIC/ZETA Converter. The use of this type of converter is expected to reduce the ripple at the output voltage and minimize voltage disturbances during switching. The control method used is a fuzzy logic controller for voltage control which is expected to produce stable output.

Abstract
Performance of the antenna is parameter in the reception of remote sensing satellite data. Gain to noise ratio becomes one of the variable conditions for satellite data transmitted from transmitters and satellite antennas to be received after power loss in a free space. Remote sensing data reception quality depends on the value of the gain to noise antenna. The Quality gain to noise determines the value of bit energy per noise received in the demodulator. The value of energy bit per noise received by a demodulator corresponds with the required energy bit per noise from modulation systems. Currently gain to noise measurements use the sun, moon, and stars by comparing the power of the transmitter with the received power in the antenna. This measurement takes a time when the antenna is full schedule. The approach in this study uses satellite power distance slant range and carrier to noise received at the receiver. Knowing the elevation angle of the satellite when it passes we can get the slant range. By using satellite transmit power parameters, free space loss, operating bandwidth, and carrier to noise in the receiver, we will find expected gain to noise antenna. The result, measurements using power satellite is success to calculate the gain to noise antenna. This newmethod makes it easier to monitor antenna availability continuously.

Abstract
Lighting devices, for instance, electric lamps hold an essential role in wide range application either for industrial or household applications which mostly for illuminating purposes. Energy Saving Lamp (ESL) gaining the scientific attention replacing outdated lighting technology such as an incandescent lamp or Glass Lighting Splinter (GLS) due to some reasons. However, in their practice, the use of ESL technology remains challenging regarding its low efficiency which arises from the high harmonic current. According to Electromagnetic Compatibility (EMC) Standard class C IEC-61000-3-2, there is a maximum permissible limit of the harmonic) current that being emitted by lighting equipment during their operational time. Thus, we attempt to analyse the Harmonic Current Emissions (HCE) that is generated by a specific brand of ESL. We employed some filters and run a performance test to solve the aforementioned problem. To optimize the investigation outcomes, we applied insertion loss analysis in the filter selection. The key finding in our observation is LC-LPF filter shows the most suitable filters fulfilling the EMC standard which potentially can be applied in ESL technology.

Abstract
Summer temperature dominates environmental degradation and water resource availability on the Tibetan Plateau (TP), affecting glacier melting, permafrost degradation, desertification and streamflow, etc. Extending summer temperature records back before the instrumental period is fundamentally important for climatic and environmental studies over long timescales. By pooling 39 tree-ring width records from the TP that show significant (P < 0.05) correlations with the summer (June–August) minimum temperature (MinT) of the nearest grid point, we reconstructed a 366-year summer MinT record for the southern TP (STP). Reconstructed and instrumental data are highly coherent within the 1950–2010 calibration interval (R
2 = 0.50, P < 0.001). The reconstruction captures major temperature anomalies, such as the coldest interval of the 1810s–1820s and unprecedented warming since the 1990s. We found that the linear trends of the instrumental and reconstructed STP summer MinTs are significantly lower than those for the larger Eurasian continent over the periods 1950–2010 and 1850–1950, respectively. The lower warming rate of STP summer MinT since 1850 could be due to increased evaporative cooling, and the absence of warming enhancement factors such as snow-albedo and energy-absorbing aerosols in summer. The reconstructed summer warming rate for the STP appears to be significantly overestimated by the ensemble mean of the Coupled Model Intercomparison Project Phase 5 (CMIP5) historical simulation.
Latitudinal heterogeneity and hotspots of uncertainty in projected extreme precipitation

Published: November 2019

Abstract
Projected precipitation from climate models is used in a wide range of fields for climate change impact assessment. However, the spatial pattern of uncertainty across latitudes and the global uncertainty hotspots are not well understood despite their importance for regional adaptation planning. In this study, we describe uncertainties in projected extreme precipitation changes per K global warming across latitudes, and decompose the overall uncertainty into climate model and internal variability uncertainties. We then identify global uncertainty hotspots and discuss the broader implications. Our results show that both uncertainty sources are highly heterogeneous across latitudes, while climate model uncertainty exceeds internal variability uncertainty for all seasons and precipitation intensities. The largest difference between model and internal variability uncertainties is found in tropical regions where model uncertainty is thrice as large as internal variability uncertainty in June–July–August season and twice as large as that in the other seasons. Tropical and subtropical regions are identified as the global uncertainty hotspots, with the Sahara desert and the southern part of the Middle East being the local hotspots. The large uncertainty in the tropics and subtropics is primarily due to the convective nature of rainstorms which cannot be adequately represented by coarse-scale climate models, and also to sparse observation networks based on which climate models can be tuned and improved. The results highlight areas where future model development and improvement efforts should focus to reduce the overall uncertainties in projected precipitation extremes.
Regionalization of anthropogenically forced changes in 3 hourly extreme precipitation over Europe

Published: November 2019

Abstract
Future extreme precipitation events are expected to be influenced by climate change; however, the robustness of this anthropogenically forced response in respect to projection uncertainty especially for sub-daily extremes is not fully understood. We analyze the impact of anthropogenic climate change on 3 hourly extreme precipitation with return periods ranging between 5 and 50 years over Europe using the RCA4 model ensemble simulations at 0.11° resolution. The robustness of the signals is examined based on a regionalized signal-to-noise (S2N) technique by taking the spatial pooling into account and the efficacy of the regionalization is tested by a sensitivity analysis. The results show an increasing signal in 3 hourly extreme precipitation over Europe for all seasons except summer for which a bipolar pattern (increase in the north and decrease in the south) is discerned. For the business-as-usual scenario RCP8.5, the regionalized winter 3 hourly extreme precipitation signals over 9 × 9 model grid cells are statistically significant in roughly 72%, 65%, 59% and 48% of the European area for 5, 15, 25 and 50 year return periods respectively, while 16%–21% of the area will experience significant changes in summer. The S2N values for 3 hourly extreme precipitation changes rise after the spatial pooling by about a factor of 1.4–1.7 for all seasons except summer when they decline by about a factor of 0.78. The results of sensitivity analysis reveal that the regionalization influence is sensitive—in order of decreasing importance—to season, precipitation time scale, precipitation intensity, emission scenario and model spatial resolution. The precipitation time scale is particularly important seasonally in summer and regionally in south Europe when/where short-duration convective precipitation is dominant.
Characterization of monoclonal antibodies generated to the 287–302 amino acid loop of the human epidermal growth factor receptor
Authors: Ho Eric Chun Hei , Antignani Antonella , Sarnovsky Robert , FitzGerald David 
Published: November 2019

AbstractBackground: The dysregulation of epidermal growth factor receptor (EGFR) has been implicated in the oncogenesis of various malignancies including glioblastoma and some epithelial cancers. Oncogenesis occurs from the overexpression of EGFR, often linked to gene amplification or receptor mutagenesis. The 287–302 loop in the extracellular domain is exposed completely on EGFR variant III (EGFRvIII), partially exposed on some cancers but cryptic on normal cells. We report on the generation of antibodies to this loop.Methods: The 286–303 peptide was coupled chemically to keyhole limpet hemocyanin. After immunizations, sera were assayed for reactivity to the peptide. Mice with high titers were used for hybridoma production. Purified antibodies were isolated from hybridoma supernatants, while V regions were cloned and sequenced. Receptor binding was characterized using enzyme-linked immunosorbent assay and flow cytometry. A recombinant immunotoxin was generated from the 40H3 antibody and its cytotoxic activity characterized on relevant cancer cell lines.Results: Seven monoclonal antibodies were generated to the 287–302 loop and characterized further. Each one reacted with EGFRvIII but not wild-type EGFR. Based on reactivity with the immunizing peptide, antibodies were mapped to one of three subgroups. One antibody, 40H3, also exhibited binding to MDA-MB-468 and A431 cells but not to non-cancerous WI-38 cells. Because of its unusual binding characteristics, a recombinant immunotoxin was generated from 40H3, which proved to be cytotoxic to MDA-MB-468, A431 and F98npEGFRvIII expressing cells.Conclusions: Immunization with a peptide corresponding to a cryptic epitope from EGFR can produce tumor cell-binding antibodies. The 40H3 antibody was engineered as a cytotoxic recombinant immunotoxin and could be further developed as a therapeutic agent.

AbstractPeople who inject drugs (PWID) face disparities in human immunodeficiency virus (HIV) treatment outcomes and may be less likely to achieve durable viral suppression. We characterized transitions into and out of viral suppression from 1997 to 2017 in a long-standing community-based cohort study of PWID, the AIDS Link to Intravenous Experience (ALIVE) Study, analyzing HIV-positive participants who had made a study visit in or after 1997. We defined the probabilities of transitioning between 4 states: 1) suppressed, 2) detectable, 3) lost to follow-up, and 4) deceased. We used multinomial logistic regression analysis to examine factors associated with transition probabilities, with a focus on transitions from suppression to other states. Among 1,061 participants, the median age was 44 years, 32% were female, 93% were African-American, 59% had recently injected drugs, and 28% were virologically suppressed at baseline. Significant improvements in durable viral suppression were observed over time; however, death rates remained relatively stable. In adjusted analysis, injection drug use and homelessness were associated with increased virological rebound in earlier time periods, while only age and race were associated with virological rebound in 2012–2017. Opioid use was associated with an increased risk of death following suppression in 2012–2017. Despite significant improvements in durable viral suppression, subgroups of PWID may need additional efforts to maintain viral suppression and prevent premature mortality.
