Real-time detection of microlensing has moved from proof of concept in 1994 (Udalski et al. 1994a, Alcock et al. 1994) to a steady stream of events this year. Global dissemination of these events by the MACHO and OGLE collaborations has made possible intensive photometric and spectroscopic follow up from widely dispersed sites confirming the microlensing hypothesis (Benetti 1995). Improved photometry and increased temporal resolution from follow up observations greatly increases the possibility of detecting deviations from the standard point-source, point-lens, inertial motion microlensing model. These deviations are crucial in understanding individual lensing systems by breaking the degeneracy between lens mass, position and velocity. We report here on GMAN (Global Microlensing Alert Network), the coordinated follow up of MACHO alerts.

Gravitational Microlensing

AbstractMicrolensing light curves due to single stars are symmetric and typically last for a month. So far about 4000 microlensing events have been discovered in real-time, the vast majority toward the Galactic centre. The presence of planets around the primary lenses induces deviations in the usual light curve which lasts from hours (for an Earth-mass [M⊕] planet) to days (for a Jupiter-mass [Mj] planet). Currently the survey teams, OGLE and MOA, discover and announce microlensing events in real-time, and follow-up teams (together with the survey teams) monitor selected events intensively (usually with high magnification) in order to identify anomalies caused by planets. So far four extrasolar planets have been discovered using the microlensing technique, with half a dozen new planet candidates identified in 2007 (yet to be published). Future possibilities include a network of wide-field 2m-class telescopes from the ground (which can combine survey and follow-up in the same setup) and a 1m-class survey telescope from space.

AbstractGravitational microlensing observations will lead to a census of planets that orbit stars of different populations. From 2008, ARTEMiS will provide an expert system that allows to adopt a three-step strategy of survey, follow-up and anomaly monitoring of gravitational microlensing events that is capable of detecting planets of Earth mass and below. The SIGNALMEN anomaly detector, an integral part, has already demonstrated its performance during a pilot season. Embedded into eSTAR, ARTEMiS serves as an open platform that links with existing microlensing campaigns. Real-time visualization of ongoing events along with an interpretation moreover allows to communicate “Science live to your home” to the general public.

Rapid diagnosis is key to curtailing the Covid-19 pandemic. One path to such rapid diagnosis may rely on identifying volatile organic compounds (VOCs) emitted by the infected body, or in other words, identifying the smell of the infection. Consistent with this rationale, dogs can use their nose to identify Covid-19 patients. Given the scale of the pandemic, however, animal deployment is a challenging solution. In contrast, electronic noses (eNoses) are machines aimed at mimicking animal olfaction, and these can be deployed at scale. To test the hypothesis that SARS CoV-2 infection is associated with a body-odor detectable by an eNose, we placed a generic eNose in-line at a drive-through testing station. We applied a deep learning classifier to the eNose measurements, and achieved real-time detection of SARS CoV-2 infection at a level significantly better than chance, for both symptomatic and non-symptomatic participants. This proof of concept with a generic eNose implies that an optimized eNose may allow effective real-time diagnosis, which would provide for extensive relief in the Covid-19 pandemic.

Assessment Activity

Probity audit is an independence assessment activity to ensure the goods/services procurement processes have been implemented consistently appropriate with the principle of upholding integrity, uprightness, honesty and fulfill certain occur legislation aimed for improving the accountability for the use of public sector fund. Probity audit is done in real time simultaneously with the goods/services procurement process. This study aims to evaluate the suitability of the implementation of probity audit conducted by BPKP Headquarter as agency that initiated the implementation of probity audit in Indonesia compared with the Probity audit Guidelines for Procurement of Goods/Services as criteria. The results of this study indicate that the implementation of probity audit conducted by BPKP Headquarter has been implemented adequately, but there are activities that do not fit the criteria, especially in the activities of the determination of the scope of the audit, the preparation of working papers and the follow-up monitoring of the audit results. Probity audit merupakan kegiatan penilaian (independen) untuk memastikan bahwa proses pengadaan barang/jasa telah dilaksanakan secara konsisten sesuai dengan prinsip penegakan integritas, kebenaran, kejujuran dan memenuhi ketentuan perundangan yang berlaku yang bertujuan meningkatkan akuntabilitas penggunaan dana sektor publik. Probity audit dilakukan secara real time yaitu bersamaan dengan pelaksanaan pengadaan barang/jasa. Penelitian ini bertujuan untuk melakukan evaluasi kesesuaian pelaksanaan probity audit yang dilakukan oleh BPKP Pusat selaku instansi yang menginisiasi pelaksanaan probity audit di Indonesia dibandingkan dengan kriteria berupa Pedoman Probity audit Pengadaan Barang/Jasa Pemerintah. Hasil dari penelitian ini menunjukkan bahwa pelaksanaan probity audit yang dilakukan oleh BPKP Pusat sudah dilaksanakan secara memadai, namun masih terdapat hal yang belum sesuai dengan kriteria terutama dalam kegiatan penentuan ruang lingkup audit, penyusunan kertas kerja dan pemantauan terhadap tindak lanjut hasil audit.
