3. On the Unruh effect in de Sitter space

Author

Abstract

We give an interpretation of the temperature in de Sitter universe in terms of a dynamical Unruh effect associated with the Hubble sphere. As with the quantum noise perceived by a uniformly accelerated observer in static space-times, observers endowed with a proper motion can in principle detect the effect. In particular, we study a "Kodama observer" as a two-field Unruh detector for which we show the effect is approximately thermal. We also estimate the back-reaction of the emitted radiation and find trajectories associated with the Kodama vector fields are stable., Comment: 8 pages; corrected typos; sections structure revised

15. Indium Oxide Transistors

Author

Kyndiah, A, Ablat, A, Guyot-Reeb, S, Schultz, T, Zu, FS, Koch, N, Amsalem, P, Chiodini, S, Alic, TY, Topal, Y, Kus, M, Hirsch, L, Fasquel, S, and Abbas, M

Abstract

Multiple functionality of tungsten polyoxometalate (POM) has been achieved applying it as interfacial layer for solution processed high performance In2O3 thin film transistors, which results in overall improvement of device performance. This approach not only reduces off-current of the device by more than two orders of magnitude, but also leads to a threshold voltage reduction, as well as significantly enhances the mobility through facilitated charge injection from the electrode to the active layer. Such a mechanism has been elucidated through morphological and spectroscopic studies.

Abstract

Eighty one patients with breast cancer stages I, II and III (T3a) were given adjuvant treatment with tamoxifen (Nolvadex), chemotherapy, or both. Most patients had estrogen and progesterone receptors measurement. Twenty one (63.6%) patients of the tamoxifen group were node positive, all 25 (100%) of the chemotherapy plus tamoxifen group and 13 (56.5%) of the chemotherapy alone group. Tamoxifen was administered for at least 3 years. Disease free survival and overall survival were substantially similar after treatment with tamoxifen or chemotherapy plus tamoxifen. Side effects were more numerous and severe in patients given chemotherapy. In receptor positive elderly breast cancer patients tamoxifen represents an excellent adjuvant therapy independently of disease stage. Chemotherapy should be reserved for subjects at high risk of recurrence in controlled clinical trials.

Abstract

We evaluated the congenital malformation rate in the progeny of the personnel of the Salto di Quirra military base in Sardinia.During 2011, we gathered questionnaire information on the reproductive history of 389 employees, more then 99% of those eligible for routine health surveillance.the observed congenital malformation rate (20.1 x 10(-3), 95% CI 6.3 - 33.8) was lower than that reported by the Italian Registries of Congenital Malformations, and it did not vary by exposure to radiofrequency, elf electromagnetic fields, and solvents, and by jobs associated with alleged exposure to nanoparticles or alpha radiation.Our findings suggest that the documented or alleged occupational exposures among the PISQ workforce did not increase the congenital malformation rate in the progeny.

49. Adequacy of paracardial dissection in subtotal versustotal gastrectomy

Abstract

Right and left paracardial dissection represents an obligatory step in gastrectomy for gastric cancer of the lower half of the stomach because a second-level lymphadenectomy is part of the radical surgery for malignancy at this site. Whereas right and left paracardial dissection is easily accomplished during total gastrectomy, there is doubt as to whether subtotal gastrectomy achieves the same radical clearance of these groups of lymph nodes. This study therefore compared the number of lymph nodes dissected and the frequency of metastases in these compartments in 14 patients undergoing total gastrectomy and 22 submitted to subtotal gastrectomy. The mean number of lymph nodes dissected in the right paracardial compartment was 7.1 per patient undergoing total gastrectomy and 6.7 per patient in subtotal gastrectomy (P= 0.7). The mean numbers of left paracardial lymph nodes dissected in total and subtotal gastrectomy were 3.4 and 4.1 per patient respectively (P= 0.3). These data show that the same degree of radical clearance can be achieved in these nodal compartments, irrespective of the extent of gastric resection.
