Exploration of Reaction Pathways and Chemical Transformation Networks
For the investigation of chemical reaction networks, the identification of
all relevant intermediates and elementary reactions is mandatory. Many
algorithmic approaches exist that perform explorations efficiently and
automatedly. These approaches differ in their application range, the level of
completeness of the exploration, as well as the amount of heuristics and human
intervention required. Here, we describe and compare the different approaches
based on these criteria. Future directions leveraging the strengths of chemical
heuristics, human interaction, and physical rigor are discussed.Comment: 48 pages, 4 figure
Information-Matter Bipolarity of the Human Organism and Its Fundamental Circuits: From Philosophy to Physics/Neurosciences-Based Modeling
Starting from a philosophical perspective, which states that the living structures are actually a combination between matter and information, this article presents the results on an analysis of the bipolar information-matter structure of
the human organism, distinguishing three fundamental circuits for its survival, which demonstrates and supports
this statement, as a base for further development of the informational model of consciousness to a general
informational model of the human organism. For this, it was examined the Informational System of the Human Body and its components from the perspective of the physics/information/neurosciences concepts, showing specific
functions of each of them, highlighting the correspondence of these centers with brain support areas and with their projections in consciousness, which are: Center of Acquisition and Storing of Information (CASI) reflected in
consciousness as memory, Center of Decision and Command (CDC) (decision), Info-Emotional Center (IES)
(emotions), Maintenance Informational System (MIS) (personal status), Genetic Transmission System (GTS)
(associativity/genetic transmission) and Info Genetic Generator (IGG) related by the body development and
inherited behaviors. The Info Connection (IC), detected in consciousness as trust and confidence can explain the Near-Death Experiences (NDEs) and associated phenomena. This connection is antientropic and informational, because from the multitude of uncertain possibilities is selected a certain one, helping/supporting the survival and
life. The human body appears therefore as a bipolar structure, connected to two poles: information and matter. It is argued that the survival, which is the main objective of the organism, is complied in three main ways, by means of: (i) the reactive operation for adaptation by attitude; (ii) the info-genetic integration of information by epigenetic processes and genetic transmission of information for species survival, both circuits (i) and (ii) being associated to
the information pole; (iii) maintenance of the material body (defined as informed matter) and its functions, associated to the matter pole of the organism. It results therefore that the informational system of the human body is
supported by seven informational circuits formed by the neuro-connections between the specific zones of the brain
corresponding to the informational subsystems, the cognitive centers, the sensors, transducers and execution
(motor/mobile) elements. The fundamental informational circuits assuring the survival are the reactive circuit, expressible by attitude, the epigenetic/genetic circuit, absorbing and codifying information to be transmitted to the next generations, and the metabolic circuit, connected to matter (matter pole). The presented analysis allows to
extend the informational modeling of consciousness to an Informational Model of Consciousness and Organism, fully describing the composition/functions of the organism in terms of information/matter and neurosciences concep
Informational Neuro-Connections of the Brain with the Body Supporting the Informational Model of Consciousness
Introduction: The objective of this investigation is to analyse the informational circuits of the brain connections with the body from neurologic
and neuroscience point of view, on the basis of the concepts of information promoted by the Informational Model of Consciousness.
Analysis: Distinguishing between the virtual and matter-related information promoted by the Informational Model of Consciousness, the main
specific features of consciousness are analyzed from the informational perspective, showing that the informational architecture of consciousness
consists in seven groups of specific activities, defined as cognitive centres, each of them with specific distinct tasks, but correlated each other: centre
of acquisition and storing of information (memory), centre of decision and command (decision), centre of the emotional states (emotions), centre of
the body maintenance (power and health), centre of the genetic elaboration/transmission (reproduction) and the info-genetic generator, inherited
from the parents (predispositions, talents and skills). A special centre, dedicated to the connectivity with some extra-power properties of the mind
is also introduced, assuring an intimate supra-sensitive detection of the world to explain the associated phenomena of the near-death experiences.
Result: The activity of all these centres should be supported neurologically by the brain neuro-connectivity to the body and to external and
internal info-signals. On the basis of the informational analysis, the neuro-connections of the brain regions associated to the main characteristics
of the cognitive centres are highlighted, showing the anatomic and neuro-functional relation between the distinct components of the brain and
the specific operating body regions. These connections describe in terms of information the brain-body neuro-activities as informational specific
circuits, composed by the info-operational subsystems managed by the brain, and sensors, transducer and execution elements.
Conclusion: The components and connections mind-body stipulated by the Informational Model of Consciousness are supported by the
neurologic/neuroscience evidenc
Informational Mode of the Brain Operation and Consciousness as an Informational Related System
Introduction: the objective of the investigation is to analyse the informational operating-mode of the brain and to extract conclusions on the
structure of the informational system of the human body and consciousness.
Analysis: the mechanisms and processes of the transmission of information in the body both by electrical and non-electrical ways are analysed
in order to unify the informational concepts and to identify the specific essential requirements supporting the life. It is shown that the electrical
transmission can be described by typical YES/NO (all or nothing) binary units as defined by the information science, while the inter and intra
cell communication, including within the synaptic junction, by mechanisms of embodiment/disembodiment of information. The virtual received
or operated information can be integrated in the cells as matter-related information, with a maximum level of integration as genetically codified
info. Therefore, in terms of information, the human appears as a reactive system changing information with the environment and between inner
informational subsystems which are: the centre of acquisition and storing of information (acquired data), the centre of decision and command
(decision), the info-emotional system (emotions), the maintenance informational system (matter absorption/desorption/distribution), the genetic
transmission system (reproduction) and info-genetic generator (genetically assisted body evolution). The dedicated areas and components of the
brain are correlated with such systems and their functions are specified.
Result: the corresponding cognitive centres projected into consciousness are defined and described according to their specific functions. The
cognitive centres, suggestively named to appropriately include their main characteristics are detected at the conscious level respectively as: memory,
decisional operation (attitude), emotional state, power/energy status and health, associativity and offspring formation, inherited predispositions,
skills and mentality. The near-death and religious experiences can be explained by an Info-Connection pole.
Conclusion: consciousness could be fully described and understood in informational terms
Space time pixels
This paper reports the design of a networked system, the aim of
which is to provide an intermediate virtual space that will
establish a connection and support interaction between multiple
participants in two distant physical spaces.
The intention of the project is to explore the potential of the
digital space to generate original social relationships between
people that their current (spatial or social) position can
difficultly allow the establishment of innovative connections.
Furthermore, to explore if digital space can sustain, in time,
low-level connections like these, by balancing between the two
contradicting needs of communication and anonymity.
The generated intermediate digital space is a dynamic reactive
environment where time and space information of two physical
places is superimposed to create a complex common ground where
interaction can take place. It is a system that provides
awareness of activity in a distant space through an abstract
mutable virtual environment, which can be perceived in several
different ways – varying from a simple dynamic background image
to a common public space in the junction of two private spaces or
to a fully opened window to the other space – according to the
participants will.
The thesis is that the creation of an intermediary environment
that operates as an activity abstraction filter between several
users, and selectively communicates information, could give
significance to the ambient data that people unconsciously
transmit to others when co-existing. It can therefore generate a new layer of connections and original interactivity patterns; in contrary to a straight-forward direct real video and sound
system, that although it is functionally more feasible, it
preserves the existing social constraints that limit interaction
into predefined patterns
The Impact of Experiential Augmented Reality Applications on Fashion Purchase Intention
Utilizing the stimulus-organism-response (SOR) model, the purpose of this study is to examine the effects of augmented reality (AR) (specifically augmentation) on consumers’ affective and behavioral response and to assess whether consumers’ hedonic motivation for shopping moderates this relationship. An experiment using the manipulation of AR and no AR was conducted with 162 participants aged between 18 and 35. Participants were recruited through snowball sampling and randomly assigned to the control or stimulus group. The hypothesized associations were analyzed using linear regression with bootstrapping. The paper demonstrates the benefit of using an experiential AR retail application (app) to positively impact purchase intention. The results show this effect is mediated by positive affective response. Furthermore, hedonic shopping motivation moderates the relationship between augmentation and the positive affective response. Because of the chosen research approach, the results may lack generalizability to other forms of augmentation. Therefore, researchers are encouraged to test the proposed model using different types of AR stimuli. Furthermore, replication of the study with other populations would increase the generalizability of the findings. Results of this study provide a valuable reference for retailers of the benefits of using AR when attempting to optimize experiential value in online environments. The study contributes to experiential retail and consumer purchase behavior research by deepening the conceptualization of the impact of experiential technologies, more specifically AR apps, by considering the role of hedonic shopping motivations.Peer reviewe
Role of Artificial Intelligence (AI) art in care of ageing society: focus on dementia
open access articleBackground: Art enhances both physical and mental health wellbeing. The health
benefits include reduction in blood pressure, heart rate, pain perception and briefer
inpatient stays, as well as improvement of communication skills and self-esteem. In
addition to these, people living with dementia benefit from reduction of their noncognitive,
behavioural changes, enhancement of their cognitive capacities and being
socially active.
Methods: The current study represents a narrative general literature review on
available studies and knowledge about contribution of Artificial Intelligence (AI) in
creative arts.
Results: We review AI visual arts technologies, and their potential for use among
people with dementia and care, drawing on similar experiences to date from
traditional art in dementia care.
Conclusion: The virtual reality, installations and the psychedelic properties of the AI
created art provide a new venue for more detailed research about its therapeutic use in
dementia
OpenPING: A Reflective Middleware for the Construction of Adaptive Networked Game Applications
The emergence of distributed Virtual Reality (VR) applications
that run over the Internet has presented networked game
application designers with new challenges. In an environment
where the public internet streams multimedia data and is
constantly under pressure to deliver over widely heterogeneous
user-platforms, there has been a growing need that distributed VR
applications be aware of and adapt to frequent variations in their
context of execution. In this paper, we argue that in contrast to
research efforts targeted at improvement of scalability, persistence
and responsiveness capabilities, much less attempts have been
aimed at addressing the flexibility, maintainability and
extensibility requirements in contemporary distributed VR
platforms. We propose the use of structural reflection as an
approach that not only addresses these requirements but also
offers added value in the form of providing a framework for
scalability, persistence and responsiveness that is itself flexible,
maintainable and extensible. We also present an adaptive
middleware platform implementation called OpenPING1 that
supports our proposal in addressing these requirements
