Nitrogen starvation induces developmental transitions in cyanobacteria. Whereas complex multicellular cyanobacteria of the order Nostocales can differentiate specialized cells that perform nitrogen fixation in the presence of oxygenic photosynthesis, non-diazotrophic unicellular strains, such as <i>Synechococcus elongatus</i> or <i>Synechocystis</i> PCC 6803, undergo a transition into a dormant non-growing state. Due to loss of pigments during this acclimation, the process is termed chlorosis. Cells maintain viability in this state for prolonged periods of time, until they encounter a useable nitrogen source, which triggers a highly coordinated awakening process, termed resuscitation. The minimal set of cellular activity that maintains the viability of cells during chlorosis and ensures efficient resuscitation represents the organism’s equivalent of the BIOS, the basic input/output system of a computer, that helps “booting” the operation system after switching on. This review summarizes the recent research in the resuscitation of cyanobacteria, representing a powerful model for the awakening of dormant bacteria.

As we have previously mentioned, the computer itself is simply a collection of chips and circuit boards which are useless without software. Application software is what you do work with, i.e. your word processor or database etc, but the application software itself needs an operating system to run within. The operating system, however, needs something called a basic input/output system (BIOS) to operate. This is software but stored in ROM (Read Only Memory) on chips, and tells the computer what to do when it is first switched on.

Input-output tables with input-output data represent a relatively simple but useful tool to analyze the structure of the economy or undergoing structural changes. These tables enable to quantify direct and indirect linkages within each economy, as well as to study demand or supply relationships between particular sectors. The aim of this paper is to present and compare the main characteristics of 2 selected sectors for Slovakia and Austria. The focus is on the agriculture and food sector and their characteristics using the input output data and analysis. We compared basic input and output multipliers in order to verify the similarities in the position and the development of these sectors in selected countries. Other objectives were analysis of sectors’ backward and forward linkages, “measuring” of their strengths, the identification of key industries and concentration of their impacts. With accordance to our previous research and general trends, we expected a certain decline of importance over the analyzed period of 2000-2014.

Interaction between medical image platform and external environment is a desirable feature in several clinical, research, and educational scenarios. In this work, the integration between 3D Slicer package and Arduino board is introduced, enabling a simple and useful communication between the two software/hardware platforms. The open source extension, programmed in Python language, manages the connection process and offers a communication layer accessible from any point of the medical image suite infrastructure. Deep integration with 3D Slicer code environment is provided and a basic input–output mechanism accessible via GUI is also made available. To test the proposed extension, two exemplary use cases were implemented: (1) INPUT data to 3D Slicer, to navigate on basis of data detected by a distance sensor connected to the board, and (2) OUTPUT data from 3D Slicer, to control a servomotor on the basis of data computed through image process procedures. Both goals were achieved and quasi-real-time control was obtained without any lag or freeze, thus boosting the integration between 3D Slicer and Arduino. This integration can be easily obtained through the execution of few lines of Python code. In conclusion, SlicerArduino proved to be suitable for fast prototyping, basic input–output interaction, and educational purposes. The extension is not intended for mission-critical clinical tasks.

Many person or institutions are still not aware of security on a server, not only rely on IDS and IPS applications and some firewall applications that we can easily find through internet networks. Special security handling is required on servers that are not related to third-party applications. The security design can be implemented through kernel configuration and tweaks that can be done by relying on the default application of an operating system. These applications are very common and can be found in almost all types of Linux server distributions. And there are still many people who do not maximize the security provided by the BIOS (Basic Input Output System) so that the operating system that has been installed and the data stored therein can be easily accessed by parties who are not responsible. Than as a preventive measure so that the data stored can not be accessed haphazardly by people who are not responsible, provided encryption and the sharing of system files that will be installed on the server. In the security steps for account access, the password that is created will be expired and the user cannot use the old password that he has used before

The protection of Computer Hardware and Software using Cryptographic algorithms has assumed importance in the recent years. The Trusted Computing Group (TCG) has put forward certain conditions to be met by the computer hardware, software and firmware so that the devices may be considered trusted. The Trusted Platform Module is a hardware device that will authenticate the code modules contained in the Basic Input/Output System (BIOS) of a computer to ensure that the Computer System starts in a trustworthy state. This device can also protect against Memory Management attacks including Buffer Overflows and Memory Pointer attacks.
