"Higgs Boson telah ditemukan pada tahun 2012 di Large Hadron Collider LHC. Higgs Boson meluruh secara dominan menjadi partikel bottom anti bottom bb, dari tumbukan proton anti proton menghasilkan sinyal yang sama dengan top anti top tt jets. Dalam peluruhan Higgs Boson, Higgs tersebut masih belum dapat dibedakan dari reaksi latar belakang bb. Penelitian ini akan menyajikan pembelajaran sistematis tentang machine learning ML menggunakan metode neural network untuk membedakan ttH pada peluruhan H --> bb. Penelitian inimenggunakan metode fenomenologi serta simulasi untuk membentuk event, kemudian komputasi sebagai alat untuk seleksi event dan ML. Adapun hasil yang diperoleh adalah diskriminasi yang hanya menghasilkan efisiensi testing sebesar 2.7 sehingga perlu optimasi rekonstruksi top quark yang lebih menyeluruh agar menghasilkan variabel yang lebih kuat untuk didiskriminasi.

Higgs Boson has been discovered in 2012 in the Large Hadron Collider LHC. Higgs Boson decays predominately into bottom bottom particles bb, from proton collisions producing the same anti proton signals as top anti top tt jets with heavy flavor. In the decay of Higgs Boson, the Higgs is still indistinguishable from the background reaction bb. This study will present systematic learning about machine learning ML using the neural network method to distinguish ttH on decay H bb. The methods that were used on this research were phenomenology, simulation to generate event, then computation as tool for event selection and ML. The result obtained were discrimination that only produced testing efficiency 2.7 so it needs more optimization of top quark reconstruction to produce stronger variable to be more discriminated."

"For this paper, we consider the resulting 3-D inversion using inversion modeling, which is motivated by developing theory and the recent application of the Magnetic Resonance Sounding (MRS) technique in detecting and mapping of subsurface groundwater. MRS is a non-invasive method which directly detects the groundwater’s existence from surface measurements. A pulse current, at a proper frequency, is transmitted into a loop. After hydrogen atoms of water molecules in the subsurface are energized by pulses of alternative currents, the magnetic resonance field is produced by the H protons is measured within the same loop. Generally, MRS has two observable factors: initial amplitude and decay time. The aim of three-dimensional inversion is to extract the information, i.e., the value and distribution of two physical parameters of the subsurface conditions: water content and subsurface properties (pore and grain size). Additionally, we present a general formulation for inverting the initial amplitude and decay time of the MRS data to recover a 3-D distribution of groundwater. The forward problem was solved using an integral equation method in the spatial domain. An improved Levenberg-Marquardt strategy was employed to solve the inverse problem. Two synthetic examples are illustrated to determine the basic functionality of the inversion algorithm. The real data results show applicability and relevance in larger-scale field examples."

"This study proposes a method of optimizing the dry storage design for nuclear-spent fuel from the G.A. Siwabessy research reactor at National Nuclear Energy Agency of Indonesia (BATAN). After several years in a spent fuel pool storage (wet storage), nuclear spent fuel is often moved to dry storage. Some advantages of dry storage compared with wet storage are that there is no generation of liquid waste, no need for a complex and expensive purification system, less corrosion concerns and that dry storage is easier to transport if in the future the storage needs to be sent to the another repository or to the final disposal. In both wet and dry storage, the decay heat of spent fuel must be cooled to a safe temperature to prevent cracking of the spent fuel cladding from where hazardous radioactive nuclides could be released and harm humans and the environment. Three optimization scenarios including the thermal safety single-objective, the economic single-objective and the multi-objective optimizations are obtained. The optimum values of temperature and cost for three optimization scenarios are 317.8K (44.7°C) and 11638.1 US$ for the optimized single-objective thermal safety method, 337.1K (64.0°C) and 6345.2 US$ for the optimized single-objective cost method and 325.1K (52.0°C) and 8037.4 US$ for the optimized multi-objective method, respectively."

"ABSTRAKPendahuluan Infeksi pneumonia nosokomial (PN) merupakan masalah utama di negara berkembang terutama pada pasien yang menjalani bedah jantung dan mendapat perawatan di intensive care unit (ICU). Aspirasi mikroorganisme dari kolonisasi rongga mulut merupakan salah satu faktor risiko PN yang perlu diperhatikan. Tujuan penelitian ini adalah untuk mengetahui dapat tidaknya kondisi rongga mulut menjadi prediktor terjadinya PN. Metode Penelitian ini adalah penelitian kohort prospektif. Subjek penelitian merupakan pasien bedah jantung elektif. Kondisi rongga mulut diwakili oleh oral hygiene index - simplified (OHI-S), decay missing filled - teeth (DMF-T) serta laju aliran saliva tanpa stimulasi (LASTS) diukur pada prabedah dan pascabedah. Terjadinya PN dinilai melalui dua parameter diagnosis yaitu clinical pulmonary infection score (CPIS) dan PN yang didiagnosis berdasarkan pengkajian klinis dokter (diagnosis klinis PN). Hasil Pada penelitian ini didapatkan 35 subyek penelitian yang memenuhi kriteria inklusi selama Desember 2012 hingga Maret 2013. Hasil analisis statistik tidak menunjukkan kemaknaan hubungan antara OHI-S, DMF-T, LASTS dengan CPIS(p=0,420; p=0,268; p=0,949). Demikian pula dengan OHI-S, DMF-T tidak terbukti mempunyai hubungan dengan diagnosis klinis PN (p=0,484; p=0,656). Namun, LASTS mempunyai hubungan signifikan dengan diagnosis klinis PN (p=0,017). Rerata LASTS pascabedah mengalami penurunan bermakna dibandingkan dengan prabedah (p=0,000). Kesimpulan Dalam penelitian ini, kondisi rongga mulut belum dapat terbukti sebagai prediktor terjadinya PN walaupun terdapat hubungan antara LASTS dengan PN yang didiagnosis melalui pengkajian klinis dokter.

ABSTRACTIntroduction Nosocomial pneumonia (NP) is a major problem in developing countries, particularly in patients undergoing cardiac surgery and who received treatment in the intensive care unit (ICU). Aspiration of oral microorganism colonization is one of the substantial risk factors. The aim of this study was to determine whether the condition of the oral cavity can be a predictor of NP. Methods A cohort prospective study was performed in this study. Subjects are elective cardiac surgery patients. Oral conditions examination defined by oral hygiene index ? simplified (OHI-S), decay missing filled - teeth (DMF-T) and unstimulated salivary flow rate (SFR) was implemented pre-surgery and post-surgery. Diagnosis of NP was evaluated through two parameters. There were clinical pulmonary infection score (CPIS) and clinical assessment of NP. Results There were 35 subjects participating in this study who meet inclusion criteria since December, 2012 to March, 2013. Statistic analyses have not been able to confirm the link between OHI-S, DMF-T, SFR to CPIS (p=0.420; p=0.268; p=0.949). Similarly, relation of OHI-S, DMF-T and clinical NP has not proven (p=0.484; p=0.656). However, SFR was significantly related to clinical assessment of NP (p=0.017). The mean of post-surgery SFR was remarkably lower than pre-surgery (p=0.000). Conclusions In this study, the oral conditions have not been shown to be predictors of the occurrence of PN although there is a link between SFR and clinical assessment of NP."
