TOtem STtrip Edgeless Radiation hard detectors (TOTEM)
In silicon devices fabricated with standard planar technology a portion of the volume
is lost to be dedicated generally to protective structures which control the stability of
the working performance. In the specific case of silicon detectors these protective
structures surround the whole device and for radiation hard applications, where high
voltage is required, extend for more than 1mm with the consequence of a wide
insensitive area at the edges.
In view of an extension of the TOTEM program requiring a specifically radiation hard
microstrip detector with the same sensitivity at the edge further developments to
improve the detector performance are mandatory.
The frame of this specific CERN LHC INTAS call is a great opportunity to pursuit
these studies with the possibility to enlarge the initial collaboration between CERN
and the NIS institutes to a Consortium where other INTAS institutes can provide
complementary expertise and facilities requested in the development of radiation hard
planar edgeless detector
Nonequilibrium excitation of C-2 radicals during the thermal decomposition of C3O2 behind shock waves
C-2 concentrations and populations of the ground and the first excited vibrational levels of electronically excited C-2(d(3)Pi) radicals during the thermal decomposition of C3O2 behind shock waves were monitored by emission and absorption measurements in the (0-0) and the (1-0) Swan-bands. Experiments were carried out in mixtures of 1% C3O2 + Ar and 1% C3O2 + He at T = 2100-3200 K and p =1.5-7.5 bar. In the whole range of conditions studied an essential nonequilibrium of electronic and vibrational states of nascent C-2 radicals was observed. For analyzing possible formation and consumption reactions of the excited C-2 radicals, a convenient kinetic scheme of the C3O2 decomposition was developed, which considers both the recombinative pumping process and exchange and quenching reactions of the C-2(d(3)Pi, v = 0, 1) states
Research of cross-platform stream symmetric ciphers implementation
In this paper, the modern symmetric stream ciphers Enocoro, Decim, Grain, HC, MUGI, Mickey, Rabbit, RC-4, Salsa20, SNOW2.0, Sosemanuk, Strumok, Trivium, and a block cipher AES, which can be used in streaming encryption modes, are being researched. The main results of testing the rate of formation of a key stream with cross-platform implementation of encryption algorithms in the Java programming language on operating systems Windows 10 (x64), Debian (Kali) and Android (x64) are presented. Testing was conducted on a portable personal computer (Intel Pentium 3550m 2.3GG, RAM 4Gb (1600MGt)) and on a mobile device, in particular, on a smartphone (Samsung galaxy S7)

Comparison of properties of carbon particles formed by pyrolysis of C3O2 and C2H2 behind shock waves
Various carbon particles formed by the pyrolysis of C3O2 and C2H2 behind shock waves in the temperature range 1200-3800 K are studied. The formation of the condensed carbon particles is observed directly by the multichannel detection of the time profiles of the extinction of the medium in the UV, visible, and near-IR spectral regions. The samples of carbon material deposited on the walls of a shock tube after an experiment are analyzed using transmission electron microscopy with different resolutions and electron microdiffraction. Particles formed from C3O2, and C2H2 at 1500-2000 K are 10-30 nm in size and look like usual soot. The absence of molecular hydrogen in C3O2 only results in faster formation and graphitization. At 2100-2600 K, the formation of particles is retarded, and the yield of the carbon particles decreases for both substances. After experiments on pyrolysis of C3O2 at these temperatures, giant spherical particles up to 700 nm in size are found on the walls of the shock tube. Carbon particles formed at the highest temperatures (2700-3200 K) in C3O2 pyrolysis have the high degree of crystallinity of particles
Clinical response after two cycles compared to HER2, Ki-67, p53, and bcl-2 in independently predicting a pathological complete response after preoperative chemotherapy in patients with operable carcinoma of the breast
Introduction To investigate the predictive value of clinical and biological markers for a pathological complete remission after a preoperative dose-dense regimen of doxorubicin and docetaxel, with or without tamoxifen, in primary operable breast cancer. Methods Patients with a histologically confirmed diagnosis of previously untreated, operable, and measurable primary breast cancer (tumour (T), nodes (N) and metastases (M) score: T2-3(>= 3 cm) N0-2 M0) were treated in a prospectively randomised trial with four cycles of dose-dense (bi-weekly) doxorubicin and docetaxel (ddAT) chemotherapy, with or without tamoxifen, prior to surgery. Clinical and pathological parameters (menopausal status, clinical tumour size and nodal status, grade, and clinical response after two cycles) and a panel of biomarkers (oestrogen and progesterone receptors, Ki-67, human epidermal growth factor receptor 2 (HER2), p53, bcl-2, all detected by immunohistochemistry) were correlated with the detection of a pathological complete response (pCR). Results A pCR was observed in 9.7% in 248 patients randomised in the study and in 8.6% in the subset of 196 patients with available tumour tissue. Clinically negative axillary lymph nodes, poor tumour differentiation, negative oestrogen receptor status, negative progesterone receptor status, and loss of bcl-2 were significantly predictive for a pCR in a univariate logistic regression model, whereas in a multivariate analysis only the clinical nodal status and hormonal receptor status provided significantly independent information. Backward stepwise logistic regression revealed a response after two cycles, with hormone receptor status and lymph-node status as significant predictors. Patients with a low percentage of cells stained positive for Ki-67 showed a better response when treated with tamoxifen, whereas patients with a high percentage of Ki-67 positive cells did not have an additional benefit when treated with tamoxifen. Tumours overexpressing HER2 showed a similar response to that in HER2-negative patients when treated without tamoxifen, but when HER2-positive tumours were treated with tamoxifen, no pCR was observed. Conclusion Reliable prediction of a pathological complete response after preoperative chemotherapy is not possible with clinical and biological factors routinely determined before start of treatment. The response after two cycles of chemotherapy is a strong but dependent predictor. The only independent factor in this subset of patients was bcl-2. Trial registration number NCT0054382
