A recent study has provided evidence that the use of contralateral prophylactic mastectomy (CPM) is increasing.[1] Over the 5-year period from 1998 to 2003, the CPM rate doubled. Prior studies have shown that the surgical procedures chosen by patients are most commonly influenced by physician and surgeon recommendation. This has been observed in the choice of CPM as well.[2] The data strongly s...
The autologous mixed lymphocyte reaction (auto-MLR) measures the ability of non-T cells to stimulate autologous T cells to proliferate in tissue culture. The auto-MLR was studied in 1 1 patients with autoimmune thrombocytopenic purpura (ATP). Seven patients had decreased auto-MLR. which averaged 4440 ± 3364 cpm (SEM) compared to 1 5.360 ± 6905 cpm for simultaneously studied controls. The averag...
(LPS) is rare malignant tumor of fat cells in deep soft tissue that affects adults between the ages of 40 and 60 [1]. This tumor is extremely aggressive with high morbidity and mortality. World Health organization classifies LPS into five subtypes: well-differentiated (WDLPS)/Atypical lipomatous tumors (ALT); dedifferentiated (DDLPS); myxoid (MLPS); pleomorphic (PLPS); and mixed type LPS [2]. M...
در این مقاله، به بررسی اثر پارامترهای کاری گوناگون بر شکل تپهای خروجی یک لیزر 2CO تپی فشار اتمسفری پرتکرار دستساز (با آهنگ تکرار تا kHz 1) پرداخته شده است. راستا، عوامل گوناگونی همچون: نسبت گاز 2N، He و بازتابندگی آینه جلویی تغییر داده شدند انرژی گسیلی هر از حالتها ثبت مشخصهیابی شدند. نشان شد که با گازهای 2N He، میتوان دیرش زمانی میخه دنبالهی تپها را بازهی ns 140-95 µs 5/3-5/1 تنظیم نم...
Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFDM systems with conventional memoryless mappers such as BPSK and QPSK. In this paper, the ability of CPM mappers in an OFDM system to reduce ...
High peak-to-average power ratio of the transmit signal is a major drawback of multicarrier transmission such as OFDM. This paper describes Orthogonal Frequency Division Multiplexing (OFDM) system with Continuous Phase Modulation (CPM) mappers is considered. Such a system is known to provide superior bit error rate performance by virtue of the memory introduced by the CPM mapper compared to OFD...
Continuous phase modulations (CPM) represent a family of non-linear coded modulation schemes characterize by a constant envelope and continuity of the phase. The constant envelopes permit the use of very efficient non-linear power amplifiers in the transmitter, while level phase variations result in a compact spectrum. These modulations are classified as single-h CPM schemes and have been used ...
INTRODUCTION Contralateral prophylactic mastectomy (CPM) is an option for women who wish to reduce their risk of breast cancer or its local recurrence. There is limited data on demographic differences among patients who choose to undergo this procedure. METHODS The population-based Florida cancer registry, Florida's Agency for Health Care Administration data, and US census data were linked an...
This paper is the second part of a two-part paper devoted to the study of the spectral correlation of CPM modulations. The first part gave the exact analytical expression of the theoretical spectral correlation for the special case of the CPKSF modulations (CPM 1-REC). A generalisation to all CPM modulations (full response CPMs other than 1-REC, and partial response CPMs) seems to be unrealisab...
