هدف این مطالعه بررسی تاثیر نسبت q توبین و نرخ رشد درآمد بر سطح سرمایه گذاری است. برای این منظور 100 شرکت از بورس اوراق بهادار تهران برای سالهای 87_1381 مورد مطالعه قرار گرفتند. شرکتها از نظر نسبت q توبین به دو گروه شرکتهایی با نسبت q توبین کوچکتر از 1 و شرکتهایی با نسبت q توبین بزرگتر از 1 تقسیم شدند. نتایج رگرسیون نشان داد که برای تمامی شرکتها نسبت q توبین بر سطح سرمایه گذاری تاثیر معنادار و م...
Forty -five year-old man with left renal mass underwent nephrectomy to reveal 20cm tumor diagnosed as sarcomatoid chromophobe renal cell carcinoma (CRCC). Lymph node metastasis of chromophobe and sarcomatoid components, disseminated tumor in retroperitoneal fat, lymphatic vessels, peri-renal adipose tissue in lymphangitic carcinomatosis pattern were identified. Chromophobe epithelial cells EMA,...
A 2-Mb critical region implicated in the microcephaly associated with terminal 1q deletion syndrome.
Patients with distal deletions of chromosome 1q have a recognizable syndrome that includes microcephaly, hypoplasia or agenesis of the corpus callosum, and psychomotor retardation. Although these symptoms have been attributed to deletions of 1q42-1q44, the minimal chromosomal region involved has not been identified. Using microsatellite and single nucleotide polymorphism (SNP) markers, we have ...
Reports of substantial evidence for genetic linkage of schizophrenia to chromosome 1q were evaluated by genotyping 16 DNA markers across 107 centimorgans of this chromosome in a multicenter sample of 779 informative schizophrenia pedigrees. No significant evidence was observed for such linkage, nor for heterogeneity in allele sharing among the eight individual samples. Separate analyses of Euro...
This paper introduces a constant-time implementation for a quasi-cyclic moderate-density-parity-check (QC-MDPC) code based encryption scheme. At a 2 security level, the software takes 14 679 937 Cortex-M4 and 1 560 072 Haswell cycles to decrypt a short message, while the previous records were 18 416 012 and 3 104 624 (non-constant-time) cycles. Such speed is achieved by combining two techniques...
Aberrations of the long arm of chromosome 1 have been linked to many diseases, both in acquired somatic neoplastic conditions and constitutional genetic disorders. These abnormalities include structural rearrangements and various deletions or amplifications affecting whole chromosome arms or specific regions. Gain of chromosome 1q has been reported in many solid tumours, including invasive carc...
We consider the problem of finding optimal “jumping” patterns from 1 to N where there is a cost associated with each jump. This will be done for two cost functions, in the first case the cost of jumping from a to b will be (1 − q)/a for 0 < q < 1, while the second cost function will be b/a. For the first cost function we will show that all the jump lengths, except possibly the last jump, are be...
Neuroblastoma is an aggressive embryonal tumor that accounts for ∼15% of childhood cancer deaths. Hitherto, despite the availability of comprehensive genomic data on DNA copy number changes in neuroblastoma, relatively little is known about the genes driving neuroblastoma tumorigenesis. In this study, high resolution array comparative genome hybridization (CGH) was performed on 188 primary neur...
