Opis:
Introduction: The industrial and socio-economic development is the direct cause of changes in major health threats in highly developed societies. Diabetes is a civilization disease and it depends on the impaired action of insulin. Together with its complications, it is a significant cause of deaths all over the world. Purpose: To assess the level and trends of potential years of life lost (PYLL) due to diabetes in Poland in the years 2002-2013. For specific purposes, it is necessary to assess the PYLL level and the dynamics of PYLL rates due to diabetes and comparison with all causes of death. Materials and Methods: The research material consists of data from generally available databases from the Polish Statistical Office. Potentially lost years of life were calculated using the method proposed by J-M Romeder. Premature deaths have been defined as deaths occurring before the age of 70. Trends in PYLL coefficients were generated by the computer program Joinpoint Regression Programme. Results: The results of the conducted analysis unambiguously indicate the increase in the PYLL ratio due to diabetes was observed in both the general population and the male population. The higher rate of PYLL growth and its much higher level in the male population, compared to the female population, point out to the fact that men die much younger because of diabetes. The dynamics of the PYLL coefficient trends connected with all causes of death indicate the reduction of premature mortality.

Opis:
I describe Archaeonothos henkgodthelpi gen. et. sp. nov., a small (estimated body mass ~40–80 g) tribosphenic metatherian from the early Eocene Tingamarra Fauna of southeastern Queensland, Australia. This taxon, known only from a single isolated upper molar (M2 or M3) is characterised by a very distinctive combination of dental features that, collectively, probably represent faunivorous adaptations. These include: a straight, elevated centrocrista; a metacone considerably taller than the paracone; a wide stylar shelf (~50% of the total labiolingual width of the tooth); reduced stylar cusps; a long postmetacrista; a small and anteroposteriorly narrow protocone; an unbasined trigon; and the absence of conules. Some of these features are seen in dasyuromorphians, but detailed comparisons reveal key differences between A. henkgodthelpi and all known members of this clade. A. henkgodthelpi also predates recent molecular estimates for the divergence of crown-group Dasyuromorphia. Similar dental features are seen in a number of other metatherians, including the South American sparassodonts, Wirunodon chanku from the ?middle–late Eocene Santa Rosa local fauna of Peru, and Kasserinotherium tunisiense from the early Eocene Chambi fauna of Tunisia, although whether A. henkgodthelpi is closely related to any of these taxa is unclear based on available evidence. I therefore refer A. henkgodthelpi to Metatheria incertae sedis. Potential relatives of A. henkgodthelpi are unknown from any other Australian fossil deposit.

Opis:
Experiments have been performed to determine the Wigner distribution and the density matrix (and for pure states the wave function) of a light mode, by using tomographic inversion of a set of measured probability distributions for quadrature amplitudes. From these measurements the quantum distributions of optical phase and photon number have been obtained. The measurements of quadrature-amplitude distributions for a temporal mode of the electromagnetic field are carried out using balanced homodyne detection. We refer to this new method as optical homodyne tomography. Given the measured density matrix, one can experimentally infer any of the various quantum distributions of optical phase, in particular the Pegg-Barnett (or, equivalently, Shapiro-Shepard) phase distribution, the marginal Wigner distribution, and the Vogel-Schleich operational phase distribution. We have used this approach to make measurements of the number-phase uncertainty relation for coherent-state fields. The coherent states do not attain the minimum value for the number-phase uncertainty product, as set by the expectation value of the commutator of the number and phase operators; this is true theoretically and experimentally.

Opis:
We generalize the standard attractive Hubbard, having an on-site pair creation operator Q$\text{}_{i}$ = a$\text{}_{i↑}$a$\text{}_{i↓}$, to one with n components Q$\text{}_{iα}$ = a$\text{}_{iα↑}$a$\text{}_{iα↓}$, α=1,2,...,n. In the limit n → ∞ we obtain the Ginzburg-Landau functional. On this basis we explore the crossover from weak (BCS) to strong coupling (Bose-Einstein condensation) superconductivity. The associated self-consistent equations for the Ginzburg-Landau parameters are similar to those of the T-matrix approach. The evolution of the band structure with increasing interaction strength is studied and correlated with the behavior of the pair propagator and the transition temperature. We find that the pairing interaction creates a new band which moves downwards in energy as the interaction strength increases and separates into a lower Hubbard band when the interaction strength becomes comparable to the band width. In the strong coupling regime, a third band with small spectral weight is also found in between the lower and upper Hubbard bands.

Opis:
This study describes a novel technique to form good quality low temperature oxide (< 350 C degree). Low temperature oxide was formed by N2O + SiH4:N2 plasma in a plasma enhanced chemical vapour deposition (PECVD) system on the silicon surface reactively etched in CF4 plasma (RIE - reactive ion etching). The fabricated oxide demonstrated excellent (for low temperature dielectric formation process) currentvoltage (I-V) characteristics, such as: low leakage current, high breakdown voltage and good reliability. Experimental results indicate that the proposed method of fluorine incorporation into the SiO2/Si inteface improves electrical parameters of MOS structures.

Opis:
This study describes the effects of high temperature annealing performed on structures fluorinated during initial silicon dioxide reactive ion etching (RIE) process in CF4 plasma prior to the plasma enhanced chemical vapour deposition (PECVD) of the final oxide. The obtained results show that fluorine incorporated at the PECVD oxide/Si interface during RIE is very stable even at high temperatures. Application of fluorination and high temperature annealing during oxide layer fabrication significantly improved the properties of the interface (Ditmb decreased), as well as those of the bulk of the oxide layer (Qeff decreased). The integrity of the oxide (higher Vbd ) and its uniformity (Vbd distribution) are also improved.

Opis:
We have investigated the influence of silicon dioxide reactive ion etching (RIE) parameters on the composition of the polymer layer that is formed during this process on top of the etched layer, and finally, the role of this layer in high-temperature thermal diffusion of boron into silicon. The polymeric layer formed on the etched surface appeared to consist of fluorine and silicon fluoride (SiOF and SiF). Concentration of these components changes depending on the parameters of RIE process, i.e., rf power, gas pressure and etching time. The composition of this polymeric layer affects, in turn, boron thermal diffusion into silicon. With increasing rf power, the depth of boron junction is increased, while increasing time of etching process reduces boron diffusion into silicon.

In near future silicon technology cannot do without ultrathin oxides, as it becomes clear from the "Roadmap'2000". Formation, however, of such layers, creates a lot of technical and technological problems. The aim of this paper is to present the technological methods, that potentially can be used for formation of ultrathin oxide layers for next generations ICs. The methods are briefly described and their pros and cons are discussed.
