High performance ambipolar organic mixed ionic-electronic conductor for adaptive logic circuits and neuromorphic electronics

Organic mixed ionic-electronic conductors (OMIECs) are central to bioelectronic applications such as biosensors, health monitoring devices and neural interfaces, and have facilitated efficient next-generation brain-inspired computing and biohybrid systems. Most OMIECs are hole-conducting (p-type) materials, while complimentary logic circuits and various biosensors require electron-conducting (n-type) materials too. Here we show an ambipolar mixed ionic-electronic polymer that achieves high on/off ratios with high ambient p- and n- type stability. We highlight the versatility of the material by demonstrating its use as a neuromorphic memory element, an adaptable ambipolar complementary logic inverter, and a neurotransmitter sensor. The ambipolar operation of this material allows for straightforward monolithic fabrication and integration, and opens a route towards more sophisticated complex logic and adaptive circuits.

A Decoder – Look up Tables for FPGAs

The FPGA (Field-Programmable Gate Array) has recently become the popular hardware and so-called LUTs (Look up Tables) are the basic of the FPGAs logic. For example, n-LUT is the MOS pass transistors multiplexer 2n-1 which input data receive SRAM cells logic function configuration (user’s projects Truth Table). Address inputs of the LUT are the variables. Therefore, we get one n-arguments logic function for the actual FPGA configuration. To get m functions (even with the same n-arguments) we should take m LUT. Authors propose a novel Decoder n-LUT (n-DC LUT), which makes possible to get m functions with the same n-arguments, like in Program Logic Array (PLA) CPLD (Complex Programmable Logic Device). DC LUT activates one of the 2n product terms outputs. Combined with OR product terms we can get m functions with the same n-arguments. To do this option we can use, for example, FPGAs typical connections units. The restriction of Meade-Conway for the FPGAs allows n=3 in one tree. Two 3-LUTs with one 1-LUTs form 4-LUT. Modern Adaptive Logic Modules (ALM) have n=8, but not all possible functions are implemented. The article deals with the design and investigation of some variants 3-DC LUT: with pull up output resistors, with orthogonal output circuits, with orthogonal transistors for each pass transistor. Simulation confirms the feasibility of the proposed method and shows that DC LUT with orthogonal output circuits is better variant of the systems realization in terms of current consumption and time delay at large n. A further development of the ALM concept may be the introduction of adaptive DC LUT, which, by tuning, can calculate single LUT function or 2n decoder functions. The proposed elements allow to increase the functionality of the FPGAs.

Changes of changes: Sociality and the lack of protection

Despite the fact that social changes are often proclaimed as a combination of positive development prospects, in practice they will not necessarily lead to positive results for everyone and in general. The sociological, ontological and cultural essence of modern changes in the mode of unreliability and redundancy of security systems is revealed. The horizon of understanding the problem in the mode of transition to a new technological order, which requires individual adaptation of people to a risk-generating environment, to a society without guarantees, is proposed. The concepts of “the lack of protection” and “the culture of control” are the basic part of the content. It has been established that digitalization is not substantial, but epiphenomenal, and that the culture of control is an imperative of digitalized sociality and dehumanization. The lack of protection is a sign of transition to the metric rationality of the culture of control, which increases the inanity of the forms and meanings of human existence simplifying it to an adaptation formula. The nature of the lack of protection is not metric, but an internal process that leads away from the adaptive logic of protection to the depth of understanding the limits of its probability in practice. The quality of this level of reflection is not determined by the pressure of changes, but is formed in the creation of thought and the upbringing of will within the social whole.

La Banda Gallega: vertebración defensiva de un espacio de frontera en el límite noroccidental del alfoz hispalense en la Baja Edad Media

The Galician Band: defensive vertebration of a frontier space in the Northwestern limit of the domains of Seville in the Late Middle AgesThe northwestern limit of the Seville domains constituted a complex frontier space of high potencial tension throughout the Late Middle Ages. Once the conquest of this historical territory was over, the council of Seville promotes the definition of a castral system destined to guarantee the guard and defense of its extensive territory. The Galician Band constituted a large network of fortifications who knew how to incorporate the existing ones and build new castles, which responded to an adaptive logic based on the poliorcetic and geopolitical requirements. The geospacial analysis carried out in this research, implemented through GIS, allowed contrasting certain hypotheses sustained from historiography regarding the territorial implementation strategy of these passive defenses. The detailed analysis of the intervisibility relations between the fortifications of the Galician Band, allowed to define its spatial link. The analyzed castramental spaces are hierarchized, presenting a progressive stratification from the border spaces into the deep lands of the Council, following a spatial pattern that allows the strategic control of the main paths of territorial penetration.

Devising the set of abnormalities for a given defeasible rule

Devising adaptive logics usually starts with a set of abnormalities and a deductive logic. Where the adaptive logic is ampliative, the deductive logic is the lower limit logic, the rules of which are unconditionally valid. Where the adaptive logic is corrective, the deductive logic is the upper limit logic, the rules of which are valid in case the premises do not require any abnormalities to be true. In some cases, the idea for devising an adaptive logic does not relate to a set of abnormalities, but to one or more defeasible rules, and perhaps also to one of the deductive logics. Defeasible rules are not universally valid, but are valid in ‘normal situations’ or for unproblematic parts of premise set. Where the idea is such, the set of abnormalities has to be delineated in view of the rules. The way in which this task may be tackled is by no means obvious and is the main topic studied in the present paper. The outcome is an extremely simple and transparent recipe. It is shown that, except for very special cases, the recipe leads to an adequate result.

Adaptive intervention logic for automated driving systems based on injury risk minimization

Performance improvement of advanced driver assistance systems yields two major benefits: increasingly rapid progress towards autonomous driving and a simultaneous advance in vehicle safety. Integration of multiple advanced driver assistance systems leads to the so-called automated driving system, which can intervene jointly on braking and steering to avert impending crashes. Nevertheless, obstacles such as stationary vehicles and buildings can interpose between the opponent vehicles and the working field of advanced driver assistance systems’ sensors, potentially resulting in an inevitable collision state. Currently available devices cannot properly handle an inevitable collision state, because its occurrence is not subject to evaluations by the system. In the present work, criteria for intervention on braking and steering are introduced, based on the vehicle occupants’ injury risk. The system must monitor the surrounding and act on the degrees of freedom adapting to the evolution of the scenario, following an adaptive logic. The model-in-the-loop, software-in-the-loop and hardware-in-the-loop for such adaptive intervention are first introduced. To highlight the potential benefits offered by the adaptive advanced driver assistance systems, simulation software has been developed. The adaptive logic has been tested in correspondence of three inevitable collision state conditions between two motor vehicles: at each instant, the adaptive logic attitude of creating impact configurations associated with minimum injury risk is ultimately demonstrated.

Governing the multicultural city: Europe’s ‘great urban expectations’ facing austerity and resurgent nativism

This article analyses European discourses on ‘optimal’ urban inclusion policies, as they are embodied in EU-sponsored city networking initiatives. Drawing from the scholarships on multiculturalism and urban austerity, it builds an inclusion agendas matrix that identifies four ideal-typical agendas for ethnic and racial inclusion: multicultural, diversity inclusion, community cohesion and neoliberalised diversity. It identifies a shift from group-based to individual-based concerns (mainstreaming) and from a politicised to a depoliticised approach to inclusion (depoliticising). It argues that (a) this double shift should be understood as the result of the mutually reinforcing pressures of nativism and austerity, and (b) inconsistencies in network discourses and policy advice suggest a pragmatic-adaptive logic that challenges simplistic understandings of cities as either (only) sites of resistance or (only) sites of full-blown accommodation of nativist and austerity imperatives.
