Judul: A Case Study of Cardiac Tamponade in A Domestic Short Hair Male Cat
Abstrak: Kucing merupakan salah satu hewan kesayangan paling populer di dunia saat ini. Salah satu penyebab utama resiko kematian mendadak pada kucing adalah penyakit jantung. Studi kasus ini bertujuan untuk menggambarkan kejadian penyakit tamponade jantung pada kucing jantan domestic short hair berusia dua tahun yang didiagnosis menggunakan ekokardiografi di Rumah Sakit Hewan Pendidikan FKH IPB University. Mode ekokardiografi yang dilakukan pada pasien adalah ekokardiografi dua dimensi Brightness-mode, Motion-mode, dan color flow doppler. Pemeriksaan dengan B-mode menunjukkan adanya efusi perikardium dan pembesaran atrium kiri. Pemeriksaan dengan M-mode menunjukkan peningkatan ketebalan inter ventricular septa-diastole, left ventricle posterior wall-diastole, dan left ventricle posterior wall-systole. Hasil tersebut menunjukkan terjadinya tamponade jantung pada kucing jantan domestic short hair. Pemeriksaan color flow doppler tidak menunjukkan adanya warna regurgitasi atau turbulensi pada katup atrio-ventrikular dan katup semilunar. Hasil menunjukkan kondisi katup yang normal., Cats are one of the most popular pets in the world today. One of the main causes of the risk of sudden death in cats is heart disease. This case study aims to describe the incidence of cardiac tamponade in a 2-year-old domestic short hair male cat diagnosed using echocardiography at IPB University Veterinary Teaching Hospital. The echocardiography modes performed in the patient were two-dimensional Brightnessmode (B-mode) echocardiography, Motion-mode (M-mode), and color flow doppler echocardiography. B-mode examination showed pericardial effusion and left atrial enlargement. M-mode examination showed an increase in the thickness of the interventricular septa-diastole, left ventricle posterior wall-diastole, and left ventricle posterior wall-systole. These results indicate the occurrence of cardiac tamponade in a male domestic short hair cat. Color flow doppler examination did not show any regurgitation or turbulence in the atrio-ventricular and semilunar valves. The results show normal valve conditions.

Judul: Kasus Kelainan Jantung Kucing secara Ultrasonografi di Rumah Sakit dan Hewan Tahun 2013–2017.
Abstrak: Penyakit jantung merupakan penyebab utama kematian mendadak pada kucing. Jenis penyakit ini dapat didiagnosis menggunakan metode ultrasonografi (USG) yang dapat memberikan gambaran struktur anatomi jantung secara langsung dan non invasive. Penelitian ini bertujuan mempelajari kasus penyakit jantung kucing yang didiagnosis menggunakan USG di Rumah Sakit Hewan Pendidikan Fakultas Kedokteran Hewan Institut Pertanian Bogor dan klinik hewan My Vets Kemang. Sebanyak 31 kucing pada Rumah Sakit dan klinik hewan tahun 2013– 2017 diindikasi memiliki penyakit jantung. Kasus penyakit jantung dibagi menjadi dua kategori yaitu kongenital dan dapatan, masing-masing kategori membahas predisposisi umur, jenis kelamin, dan ras terhadap penyakit jantung. Adapun data yang didapatkan pada rekam medis pasien berupa sinyalemen pasien, hasil pemeriksaan USG B-mode, M-mode, dan color flow dopler, sonogram, serta diagnosis dari rekam medis. Terdapat 6.5 % kasus penyakit jantung kongenital dan 93.5 % kasus penyakit jantung dapatan. Penyakit jantung kongenital yang ditemukan berupa penyumbatan aorta (3.2 %) dan ventricular septal defect (3.2 %). Penyakit dapatan yang ditemukan pada penelitian ini adalah hipertrofi kardiomiopati (83.9 %), endokardiosis (25.8 %), mitral regurgitation (3.23 %), tricuspidal regurgitation (6.5 %), dan perikarditis (3.23 %). Penyakit jantung terjadi pada kucing berumur dewasa (54.8 %), jenis kelamin jantan (54.8 %), dan ras Persian (45.1 %). Hasil dari penelitian ini menyatakan bahwa penyakit dapatan pada jantung memiliki proporsi yang lebih tinggi dibanding kongenital pada kucing. Penyakit jantung yang paling sering terjadi pada kucing adalah hipertrofi kardiomiopati. Kucing yang berumur tua, jenis kelamin jantan, dengan ras Persian lebih rentan terhadap penyakit jantung.

Judul: The Construction of Greedy SVP LLL Algorithm
Abstrak: A lattice is a set of all integer linear combination of a set of linearly independent vectors in ℝ𝑛���. The independent vectors are called bases of lattice. Any lattice can be generated from many bases, and these bases have the same cardinality. In the lattice, the most fundamental and renowned problem is the Shortest Vector Problem (SVP). SVP is a tracking problem of the shortest nonzero vector in a lattice with equivalent bases. In two dimensions, SVP problem has resolved exactly by Gauss’ algorithm. When the lattice dimension is higher than two, A.K. Lenstra, H.W. Lenstra and L. Lovasz gave a LLL algorithm to compute approximation of nonzero shortest vector in the lattice. Reduced bases solution obtained from LLL algorithm still be an approximation and has polynomial running time of arbitrary dimension which large enough. In 1994, Schnoor and Euchner modified this LLL algorithm as a new variant which later was named deep insertion LLL algorithm. This algorithm is a modified version of the LLL algorithm to the terms of the exchange step to improve the accuracy of output of LLL reduced bases and applying it to the subset sum problem. The purpose of this research are: (1) Reconstruct the LLL algorithm and deep insertion LLL algorithm using a geometric approach. (2) Construct a greedy SVP LLL algorithm. (3) Implement the three algorithms in a symbolic programming language, and evaluate them experimentally. A bases ℬ=[𝐛���1,𝐛���2,…,𝐛���𝑛���] in ℝ𝑚��� is called reduced LLL with parameter 𝛿��� if satisfies: (a) |𝜇���𝑗���𝑖���|≤12, for every integer 𝑖���,𝑗��� with 1≤𝑖���<𝑗���<𝑛���. (b)𝛿���‖𝜋���𝑗���(𝐛���𝑗���)‖2≤‖𝜋���𝑗���(𝐛���𝑗���+1)‖2, for 𝑗���=1,2,…,𝑛���−1,where 𝛿��� is a reduced parameter of real numbers with 14<𝛿���<1. The first requirement is the reduced basis 𝛿��� must “nearly orthogonal” and in its computation case, this requirement can be reached out by using the Gram-Schmidt’s orthogonalization. While the second requirement is called exchange step, or used to called as Lovasz condition. By using both of these requirements, then they establish the LLL algorithm. Then, Schnoor and Euchner modify the LLL algorithm based on the requirements of the exchange step called the deep insertion LLL algorithm, where the exchange step is based on the comparison of the projected vector in orthogonal complement [𝐛���1,𝐛���2,…,𝐛���𝑘���−1]⊥ after j-th reduction. To construct greedy SVP LLL algorithm, the requirements of the exchange step is based on purely by comparing norm of lattice 𝐛���𝑗��� with norm lattice 𝐛���𝑖��� for 𝑖���=1,2,3…,𝑗���−1. The process of insertion reduced vector after the exchange step also has done greedily. Then, we calculate the number of arithmetic operation in greedy SVP LLL algorithm for further analysis. The result of our exprimentation for three algorithms on the certain matrix size shows that the running time of the three algorithms increases propotional to the size of the matrix. The result also shows that by using 𝛿���=34 for the LLL algorithm and the deep insertion LLL algorithm, and the greedy SVP LLL algorithm which is a new variant made by using no parameter of 𝛿���, outperform of the other of two previous algorithm in terms of speed with the same output.
