the multinucleon transfer reaction in the collisions of 40 ca+^124 Sn at Ec.m.= 128.5 MeV is investigated using the improved quantum molecular dynamics model. the measured angular distributions and isotopic distributions of the products are reproduced reasonably well by the calculations. the multinucleon transfer reactions of 40 ca+^112 Sn, 58 Ni+^112 Sn, 106 cd+^112 Sn, and 48 ca+^112 Sn are also studied. this demonstrates that the combinations of neutron-deficient projectile and target are advantageous for the production of exotic neutron-deficient nuclei near N,Z =50. the charged particles’ emission plays an important role at small impact parameters in the de-excitation processes of the system. the production cross sections of the exotic neutron-deficient nuclei in multinucleon transfer reactions are much larger than those measured in the fragmentation and fusion-evaporation reactions. Several new neutron-deficient nuclei can be produced in the 106 cd+^112 Sn reaction. the corresponding production cross sections for the new neutron-deficient nuclei,101,112 Sb,103 te,and 106,107) I,are 2.0 nb,4.1 nb,6.5 nb,0.4 μb and 1.0 μb,respectively.

在過去我國各地所檢出的猪霍亂菌株中,有特異相和非特異相,但在貴陽至目前為止,所分離到的菌株则概屬非特異相。作者於1955年曾作本菌24株的非特異→特異位相變異試驗,曾發現各菌株結果不甚一致,其中20株分離到特異相;3株於通過1、2、3、5血清半固體基3代內未出現特異相;1株(240號菌)在實驗中未轉變成特異相,但產生與b及g血清凝集的細菌。為了對本菌的生物学特性作進一步觀察,乃另取本菌20株作系統實驗觀察,茲將實驗觀察結果報告於下。

to compare the bleeding patterns and tolerability of 3 different extended ring regimens with those of the standard 28- day cycle with 21 days of contraceptive vaginal ring use followed by 7 ring-free days. Methods: Following a run-in 28- day ring cycle, women were randomized to 1 of 4 regimens: monthly (28- day cycle), every other month (49- day cycle), every third month (91- day cycle), or continuous (364- day cycle). treatment duration was 1 year. Daily bleeding diary, interval visit questionnaire, and examination data were collected. Results: A total of 561 women were enrolled, 429 were subsequently randomized, and 289 (67.4% ) women completed the entire year. All schedules were well tolerated and acceptable to women, but study completion rates were higher for the shorter cycles. Bleeding days were reduced with postponement of the withdrawal bleeding (ring-free) week, but spotting days increased. For example, women using the continuous or 364 day ring cycle reported a median of zero bleeding days but 10- 12 days of spotting during the first 3 months of extended use. Unscheduled bleeding during ring use was the lowest with the traditional 28- day cycle. Adverse events, blood pressure, body weight, and laboratory findings were comparable over the 4 treatment groups. conclusion: the combination vaginal contraceptive ring can be used for extended cycles to alter the bleeding schedule. Women willing to tolerate some spotting might choose the longer extensions to have fewer menstrual periods.

A signal-plus-noise （S+N ） energy selection combining （S+N-ESc） scheme for binary phase shift keying （BPSK） signaling is proposed. the S+N-ESc selects the branch with the maximum S+N energy for detection. the advantage of the S+N-ESc is that it requires no channel estimation for diversity branch selection. the bit error rate （BER） performance of the S+N-ESc is analyzed for BPSK signaling in independent and identically distributed （i.i.d.） Rayleigh fading channels. We show that the performance of the S+N-ESc is the same as conventional signal-to-noise ratio selection combining （SNR-Sc）,which requires estimation of the fading amplitudes for branch selection.
