This paper presents a review of the basic, model-independent differences between the pre-big bang scenario, arising naturally in a string cosmology context, and the standard inflationary scenario. We use an unconventional approach in which the introduction of technical details is avoided as much as possible, trying to focus the reader’s attention on the main conceptual aspects of both scenarios...

This paper reports on the recent outcomes from our research into Unconventional Computing for sound and music using slime mould of Physarum polycephalum. This slime mould is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging behaviour it produces electrical activity corresponding to different physiological states. We developed a method to render ...

Large-scale data policies easily may have unplanned effects of ‘’homogeneity” on the available data supply. A narrowing of the scope of the data supply tailored to established research paradigms could limit the opportunities for unconventional, but also adventurous, new research directions with the risk of slowing down scientific progress. A systematic assessment of data portfolios not only on ...

In this paper, we propose the use of Alpha-Beta associative approach as an Unconventional Computing method in the pre-diagnosis of malignant tumors of breast cancer, obtaining an accurate result in a simple way; trying to avoid invasive diagnostic methods like biopsies, as far as possible. This proposal provides for the Alpha-Beta Support Vector Associative Machine created in 2008 and tested fo...

Membrane systems are parallel and bioinspired systems which simúlate membranes behavior when processing information. As a part of unconventional computing, P-systems are proven to be effective in solving complex problems. A software technique is presented here that obtain good results when dealing with such problems. The rules application phase is studied and updated accordingly to obtain the d...

This is the fourth in a series of 5 articles providing a contemporary overview and introduction to unconventional dentistry (UD) and its correlation to unconventional medicine (UM). Several common UD and UM practices are described to familiarize practitioners with a variety of theories, practices, products and treatments that specifically apply to dentistry. This brief review is not intended as...

This paper reports on the outcomes of an approach to granular synthesis using the biological computing substrate Physarum polycephalum. The plasmodium of Physarum Polycephalum is unicellular with a myriad of diploid nuclei, which moves like a giant amoeba in its pursuit of food. The organism is amorphous, and although without a brain or any serving centre of control, can respond to the environm...

Many musical instruments have interfaces which emphasise the pitch of the sound produced over other perceptual characteristics, such as its timbre. This is at odds with the musical developments of the last century. In this paper, we introduce a method for replacing the interface of musical instruments (both conventional and unconventional) with a more flexible interface which can present the in...

Magnetic skyrmion-based data storage and unconventional computing devices have gained increasing attention due to their topological protection, small size, low driving current. However, skyrmion creation, deletion, motion are still being studied. In this study, we propose a neuromorphic magnetic tunnel junction (MTJ) device with both long- short-term plasticity (LTP STP) (mixed synaptic plastic...

A novel computationally highly e cient realization of sharp symmetrical bandstop FIR lter is proposed. The new structure is derived using the frequency-response-masking technique, where the bandedge-shaping lter is derived from half-band lter by substituting each delay of the half-band lter by M delays. The masking lters are unconventional. They are quadrature lters derived from linear combinat...
