The purpose of this paper is to analyze the results of recording electrophysiological signals by nanosensors during tests on volunteers using neutral questions and questions that cause excitement.
The nanosensor-based hardware and software complex (HSC) was used for simultaneous recording of electrocardiogram, electroencephalogram and galvanic skin response during tests on volunteers using neutral questions and questions that cause excitement. The recording was carried out in real time without averaging and filtering in the extended frequency range from 0 to 10,000 Hz, level of more than 1 µV and sampling frequency equal to 64 kHz.
For the first time, the following signals were recorded by nanosensors without filtering and averaging in the measuring channels: real-time micropotentials on an electrocardiogram with a duration of 0.2 ms and a level of 1 µV or more. Also, for the first time, changes in the shape and amplitude of the P wave, slow waves on the electroencephalography (EEG), high impulse activity of the EEG and impulse activity of short duration on the GSR were recorded in response to questions that cause excitement.
The obtained results will be used for high-resolution equipment to develop additional measuring channels in existing types of equipment for psychophysiological studies.
For the first time, new data undistorted by filters was obtained on the amplitude and time parameters of electrophysiological signals in the frequency range from 0 to 10,000 Hz in response to questions that cause excitement, which was due to high sensitivity and noise immunity of nanosensors in comparison with existing electrodes for biopotential recording.
Our nation at last seems to be rousing herself to put forth her full strength, and the organisation of industry is receiving at the hands of the new National Government no less attention than the armies that are springing into being under the magnificent direction of the new Knight of the Garter, Lord Kitchener. Hearts are beating high with hope and determination to help in every way possible in this vast effort to uphold the right, and the call comes afresh to each one of us to do everything in our power at this time of National need. In the present number we gladly publish more names of comrades who have joined the forces, but could wish they were still more numerous. Are there not others who can and who will join the noble army of heroes prepared to face the enemy in the field for faith and Motherland?

The purpose of this paper is to present an effective optimization strategy applied in a physical structure optimization of a semiconductor power metal oxide semiconductor field‐effect transistor (MOSFET), with an expensive integration constraint computation.
In order to deal with inaccuracy due to inevitable numerical errors in the objective function calculation (the power losses of the power MOSFET) and in the constraint computation, the paper proposes to use the progressive quadratic response surface method (PQRSM).
The paper focuses on four aspects: the inevitable numerical errors in the power loss and the integration constraint computation; the response surface approximation (RSA) method; the PQRSM principle; and finally the comparisons of several optimization methods applied on this application problem.
An original optimization method, PQRSM, is proposed for reducing the oscillation problem of a semi‐analytical model. The optimization results of PQRSM have been compared with the evolution strategy (ES) algorithm, with similar results but faster computation.
THE recently founded Bulgarian Bibliographical Institute has produced three publications of great interest. The first of these, by Dr. T. Borov, the Director of the Institute and of the National Library of Sofia, Why do we need a Bulgarian Bibliographical Institute?, was published in 1941, before the foundation of the Institute, and, as its sub‐title indicates, is ‘an address to friends’. In it Dr. Borov reviewed briefly the position of Bulgarian bibliography and set forth what he considered should be the aims of the Institute.

Looks at the reasons for the collapse of both regimes and considers the importance of repression with these developments. Contrasts the methods of Imperial Russia with the Bolsheviks looking at Court proceedings, prison conditions, education and propaganda in prison, exile and the secret police. Concludes that whilst social support is usually seen as essential for survival of a system, repression is not regarded as a positive element but can become the method for a system’s survival and stability.

Gorbachev′s book Perestroika is used to explain why the author believes the new policy of restructuring of the Soviet economy cannot and will not work. The policies of Perestroika are introduced and evaluated and the existing socio‐economic system presented. At the end of this sceptical Western analysis, it is concluded that the policy is cosmetic restructuring and Gorbachev′s downfall, like Khruschev′s, is assured.

At the same time, new military and political factors have emerged, which determine the strategy of the Russian defense industry, rates of its development, and change of the structure. On February 8, of the current year, the chief of Pentagon, R. Gates spoke at a session of the Committee for the Armed Forces of the Chamber of Representatives of the Congress, declaring that USA should be ready to possible military conflicts with other countries including Russia and China: “We need the whole spectrum of war facilities for army involving conflicts, since we do not know what could happen in such places as Russia, China, North Korea, Iran and other.”1 As a result, the USA military policy is encircling Russia with antimissile defense systems. They are supposed to install a powerful radar in the Czech Republic and shaft-basing missiles in Poland. A superpowerful floating radar is to be transferred from Hawaii islands to Aleut islands, etc. Thus, the whole territory of Russia will be surrounded with radar-missile complexes. These activities will produce an increased attention to elaboration and manufacturing of constituents of the antimissile defense system and by-pass systems, possible withdrawal from the Treaty on conventional weapons in Europe and the Treaty on medium-range strategic missiles etc., which may change the direction and paces of development of the defense industry.

Our approach is largely historical, argument by example. We leave it to the theoreticians and empiricists to take the argument in a more technical direction.1 Throughout, we suppose that germs are self-interested and they have a research question, for example, how might our species improve the chances of survival, the answer to which might potentially benefit germs (or, harm them by less).
