"This book was inspired by the general observation that the great theories of modern physics are based on simple and transparent underlying mathematical structures – a fact not usually emphasized in standard physics textbooks – which makes it easy for mathematicians to understand their basic features. It is a textbook on quantum theory intended for advanced undergraduate or graduate students: mathematics students interested in modern physics, and physics students who are interested in the mathematical background of physics and are dissatisfied with the level of rigor in standard physics courses. More generally, it offers a valuable resource for all mathematicians interested in modern physics, and all physicists looking for a higher degree of mathematical precision with regard to the basic concepts in their field."

"Demam Berdarah Dengue (DBD), penyakit menular berbahaya yang ditularkan oleh nyamuk Aedes Aegypti, merupakan salah satu penyakit yang memiliki laju penyebaran tercepat di dunia. Karena penggunaan vaksin DBD masih diperdebatkan di berbagai negara, maka pencegahan penyakit dengue sangat bergantung terhadap pengendalian vektor dengue. Salah satu kesulitan dalam melakukan pengendalian vektor dengue adalah sulitnya menemukan daerah sumber vektor. Untuk meningkatkan akurasi dari usaha pengendalian vektor, maka penelitian mengenai analisis hot spot mengenai daerah berpotensi wabah perlu dilakukan. Pada penelitian ini, hot spot merupakan daerah yang berpotensi menjadi sumber penyebaran wabah DBD. Dengan menggunakan analisis hot spot, makadaerah potensial sumber penyakit DBD dapat dideteksi. Data yang digunakan adalah data spasial jumlah insiden DBD di Jakarta. Statistik Getis-Ord Gi* digunakan sebagai teknik dalam melakukan analisis hot spot. Metode ini menggunakan parameter dalam bentuk matriks bobot spasial yang menggambarkan relasi penyebaran penyakit DBD dari satu daerah ke daerah lain. Matriks bobot spasial yang digunakan pada penelitian ini adalah matriks Queen’s Contiguity, matriks Inverse Distance, dan matriks model radiasi.Hasil yang diperoleh dari penelitian ini mampu menggambarkan daerah-daerah yangberpotensi menjadi prioritas dalam pengendalian vektor DBD. Penelitian ini diharapkan mampu membantu pihak dinas kesehatan di provinsi DKI Jakarta dalam meningkatkan akurasi dalam usaha pengendalian vektor DBD.

Dengue fever is one of the most rapidly spreading mosquito-borne diseases in the world.

Since the use of dengue vaccines is still debatable in many countries, dengue control

mainly depends on vector control measures. One of the difficulties of dengue vector

control is the detection of vector breeding sites. To improve the accuracy of dengue

vector control measures, a study on hot spots of dengue is conducted. In this research,

hot spot refers to a site which is potentially became an epidemic source of the disease. By

applying hot spot analysis, it is possible to detect areas with high risk of dengue outbreak.

We analyze dengue incidence in Jakarta using geospatial data of dengue fever incidence

in the region on year 2016 calculated by district. Getis-Ord Gi* statistic is used as the

tool for conducting hot spot analysis. This method requires a parameter in the form of a

weight matrix representing the possibility of dengue spreading from one district to other

districts. The weight matrix is generated using Queen’s Contiguity, inverse distance, and

radiation model weight matrix. The results of the study could show the area which has the

highest potential of being a vector breeding site at a district level. The map visualization

generated by the hot spot analysis will help public health officials achieve greater accuracy

in dengue control measures. We expect that this research can be a scientific back up for

the real implementation of dengue prevention in the field."

"The amateur astronomer's guide to the deep-sky catalogs is a single compilation of the historical and modern astronomical deep-sky catalogs. It discusses their origins, compares what's in them, explains how to interpret the data they contain, and even outlines how readers can create suitable 'custom' catalogs for their own use. The last section provides a set of three deep-sky catalogs created by the author, for observers of different levels of experience, from newcomer to expert."

"This thesis presents results of Submillimeter Array (SMA) and Very Large Array (VLA) studies of massive star formation regions in the early stages of ionization, as well as an analysis of numerical simulations of the evolution of these young HII regions. The results favor a picture in which very massive stars form in accretion flows that are partially ionized and that keep accreting material from their environment."
