Introduction: Designer Cannabinoids is a newly emerging drug of abuse that gained popularity among adolescent and young adults in the past few years. These drugs are marketed as incense or potpourri under different brand names such as spice. The potency of these drugs is variable and the range of adverse effects range from simple to severe and life threatening adverse effects such as myocardial...

Though rather awkward and limited in its usage, SPICE has been used by several authors solving their various optimisation problems. In this paper we propose how some generic optimisation algorithms can be integrated into SPICE. The implemented program has proven to be an extremely efficient optimisation tool for an experienced circuit designer. It is free of charge available at our web site (ht...

Although memristive devices with threshold voltages are the norm rather than the exception in experimentally realizable systems, their SPICE programming is not yet common. Here, we show how to implement such systems in the SPICE environment. Specifically, we present SPICE models of a popular voltage-controlled memristive system specified by five different parameters for PSPICE and NGSPICE circu...

Today, we will consider a different class of matrices and establish a different type of “niceness” result, which will also be used extensively by spectral methods. In particular, we want to say something about how eigenvectors, and in particular the extremal eigenvectors, e.g., the largest one or few or the smallest one of few “look like.” The reason is that spectral methods—both vanilla and no...

In vitro mutagenesis is an alternative to induce genetic variation in vanilla (Vanilla planifolia Jacks. ex Andrews), which characterized by low diversity. The objective of this study was somaclonal V. gamma radiation and detect it using inter-simple sequence repeat (ISSR) molecular markers. Shoots previously established were multiplied Murashige Skoog culture medium supplemented with 2 mg·L−1 ...
