Private Pension Funds in Hungary: Politics, Institutions, and Performance

The new pension system launched in Hungary in 1998 is epoch-making for having introduced a mandatory private pension scheme (MPPS). However, the political decision-making on pension reform and the scheme operations have been greatly influenced by conflicts of interests among ministries, political conflicts between parties, and the presence of special interest groups, including trade unions and financial institutions. This situation may have had a certain negative influence on the legal framework of the MPPS and on the management performance of private pension funds. In order for the MPPS to be sustainable in the future and to make insurance beneficiary profits a top priority, the corporate governance reform of pension funds and reinforcement of the monitoring system over them, and political neutralization of the public pension system are necessary.

Constraint on Heavy Element Production in Inhomogeneous Big-Bang Nucleosynthesis from The Light-Element Observations

We investigate the observational constraints on the inhomogeneous big-bang nucleosynthesis that Matsuura et al. suggested the possibility of the heavy element production beyond ${}^7$Li in the early universe. From the observational constraints on light elements of ${}^4$He and D, possible regions are found on the plane of the volume fraction of the high density region against the ratio between high-and low-density regions. In these allowed regions, we have confirmed that the heavy elements beyond Ni can be produced appreciably, where $p$- and/or $r$-process elements are produced well simultaneously.Comment: 11 pages, 7 figures, 4 Tables., accepted in Journal of Astrophysics. arXiv admin note: substantial text overlap with arXiv:1007.046

Recent progress in silica aerogel Cherenkov radiator

In this paper, we present recent progress in the development of hydrophobic silica aerogel as a Cherenkov radiator. In addition to the conventional method, the recently developed pin-drying method for producing high-refractive-index aerogels with high transparency was studied in detail. Optical qualities and large tile handling for crack-free aerogels were investigated. Sufficient photons were detected from high-performance aerogels in a beam test.Comment: Proceedings of 2nd International Conference on Technology and Instrumentation in Particle Physics (TIPP 2011), to be published in Physics Procedia, 8 pages, 7 figure

Coexistence of malignant phyllodes tumor and her2-positive locally advanced breast cancer in distinct breasts: A case report

AbstractIntroductionPhyllodes tumor of the breast is a rare biphasic neoplasm, accounting for less than 1% of all breast tumors. Coexistence of phyllodes tumor and breast cancer in distinct breasts is extremely rare.Case presentationA 47-year-old Japanese woman presented with bilateral breast lumps. A HER2-positive, unresectable invasive carcinoma in the right breast and fibroadenoma in the left were diagnosed via core needle biopsy. During chemotherapy with anti-HER2 therapy, the breast cancer shrank quickly, while the left breast lump suddenly enlarged. Under a diagnosis of malignant neoplasm of the breast, left mastectomy was performed. Malignant phyllodes tumor was diagnosed by postoperative histological examination and recurred in multiple areas as early as 2 months after surgery.DiscussionOnly 10 cases of coexisting phyllodes tumor and breast cancer in distinct breasts have been reported in the English literature. Phyllodes tumor associated with breast cancer in distinct breasts tends to be malignant. This is the first case of phyllodes tumor rapidly enlarging during anti-HER2 chemotherapy for locally advanced HER2-positive breast cancer.ConclusionEven during effective treatment of advanced or recurrent breast cancer, attention should also be paid to the contralateral breast for the possible association of a second malignancy such as phyllodes tumor
