Both the idea and technology for connecting sensors and actuators to a network to remotely monitor and control physical systems have been known for many years and developed accordingly. However, a ...little more than a decade ago the concept of the Internet of Things (IoT) was coined and used to integrate such approaches into a common framework. Technology has been constantly evolving and so has the concept of the Internet of Things, incorporating new terminology appropriate to technological advances and different application domains. This paper presents the changes that the IoT has undertaken since its conception and research on how technological advances have shaped it and fostered the arising of derived names suitable to specific domains. A two-step literature review through major publishers and indexing databases was conducted; first by searching for proposals on the Internet of Things concept and analyzing them to find similarities, differences, and technological features that allow us to create a timeline showing its development; in the second step the most mentioned names given to the IoT for specific domains, as well as closely related concepts were identified and briefly analyzed. The study confirms the claim that a consensus on the IoT definition has not yet been reached, as enabling technology keeps evolving and new application domains are being proposed. However, recent changes have been relatively moderated, and its variations on application domains are clearly differentiated, with data and data technologies playing an important role in the IoT landscape.
Supersymmetric Quantum Mechanics is commonly used to generate time independent Hamiltonians with a desired spectrum. This technique can be generalized to construct time dependent potentials. In this ...work, the harmonic oscillator and a coherent state are taken to perform a generalized SUSY transformation in order to obtain a time dependent anharmonic oscillator.
We present a phenomenological framework based on the MIT bag model to estimate the pressure experienced by quarks and gluons inside nucleons. This is accomplished by implementing non-extensive ...Tsallis statistics for the two-component system. In this model of hadrons, the strong interaction generates correlations effectively described by the q-Tsallis parameter. The resulting hadron pressure exhibits general agreement with recent calculations derived from Lattice QCD. Additionally, we compared this pressure with data extracted from deep virtual Compton scattering experiments and gravitational form factor analyses. The extended bag model provides an alternative interpretation of bag pressure in terms of the q-Tsallis parameter. Consequently, the MIT bag model can be expressed without requiring the inclusion of the bag pressure parameter.
Abstract
We studied the behavior of charge carriers in graphene nanoribbons with zigzag edges. We start from free nanoribbons, and by using second-order confluent supersymmetry, we added external ...magnetic fields perpendicular to the graphene layer. The technique allows us to obtain explicit expressions for the solution of the Dirac equation and gives the transcendental equations that must be solved to obtain the energy spectrum.
In this article, we apply a time-dependent Darboux transformation for the construction of PT-symmetric multimode optical waveguides where the non-separable complex fluctuations of the refractive ...index confine guided modes. We focus on a family of settings based on the hyperbolic Pöschl-Teller potential well. We show that the transformed systems have a "missing" state, an extra guided mode whose analog does not exist in the original system.
Introduction
Patients with autism spectrum disorder are characterized by high anxiety when facing social situations and dealing with interpersonal relationships on a daily basis. Although initially ...because of their rigid personality with the norm, and their tendency to social distancing, we do not have in mind this pathology as the most likely to develop a substance use disorder. However, it is observed in the literature a remarkable percentage of patients who resort to consumption, mainly alcohol, as an anxiolytic to be able to interact in society.
Objectives
To show the case of a 19-year-old adult with a diagnosis of ASD who resorts to alcohol consumption in her daily life as a strategy to manage anxiety in social situations.
Methods
Case report and literatura review
Results
This is a 19-year-old woman with a recent diagnosis of ASD. She is studying biotechnology and lives with her parents and 3 siblings. The patient reports difficulty in social relationships since early childhood, with experiences of school bullying. She expresses desire to relate with others, although she does it in an inadequate way, with difficulty in detecting nonverbal language, irony and anger when she does not understand a joke. The patient confesses that since she was 16 years old she has consumed alcohol to mitigate the anxiety caused by facing a group of people. She says that she feels that it relaxes her and facilitates interaction, making it more fluid and less tense. However, she recognizes that initially she used to drink 1 or 2 beers, but now she needs to drink up to 2 glasses of gin, recognizing this as something problematic.
Conclusions
The literature shows how patients with ASD can also present substance use disorder. It has been shown that about 10% of these patients have an abusive use of alcohol. Other samples show wider ranges (7-71%) of prevalence of alcohol consumption in patients with autism. In relation to cannabis, it is seen that around 3% of these patients consume it. These patients seek its anxiolytic effect and to reduce mental health symptoms. In addition, the purchase of alcohol does not involve high social interaction to obtain it, since it is a substance that can be purchased legally. It is important to explore alcohol consumption in consultation with patients with ASD to help them develop more functional anxiety management strategies.

One of the key challenges to understanding patterns of β diversity is to disentangle deterministic patterns from stochastic ones. Stochastic processes may mask the influence of deterministic factors ...on community dynamics, hindering identification of the mechanisms causing variation in community composition. We studied temporal β diversity (among-year dissimilarity) of macroinvertebrate communities in near-pristine boreal streams across 14 years. To assess whether the observed β diversity deviates from that expected by chance, and to identify processes (deterministic vs. stochastic) through which different explanatory factors affect community variability, we used a null model approach. We observed that at the majority of sites temporal β diversity was low indicating high community stability. When stochastic variation was unaccounted for, connectivity was the only variable explaining temporal β diversity, with weakly connected sites exhibiting higher community variability through time. After accounting for stochastic effects, connectivity lost importance, suggesting that it was related to temporal β diversity via random colonization processes. Instead, β diversity was best explained by in-stream vegetation, community variability decreasing with increasing bryophyte cover. These results highlight the potential of stochastic factors to dampen the influence of deterministic processes, affecting our ability to understand and predict changes in biological communities through time.
Introduction
The first definition of PAS, enunciated by Richard Gardner in 1985, refers to a disorder originating in the context of legal conflicts related to child custody. Its main characteristic ...would be a smear campaign by the child towards a parent, in the absence of plausible arguments. In this context, the child would experience an oppositional and dichotomous feeling towards his or her parents. In recent years, the presence of PAS has become increasingly important, both in the legal and health fields, largely due to the controversy and debate surrounding its approval and recognition, and there is currently no consensus on the matter.
Objectives
The main objective of this work is to examine the current state of PAS in depth in the different fields in which it is emerging: the medical-scientific and legal spheres. The current controversies and debate, both scientific and legal, will be developed. Research will be carried out on the origin of the concept and its evolution, its symptomatic presentation, the neuropsychological consequences in minors, the role and legal value of expert reports, as well as the existing evaluation methods for the assessment of PAS.
Methods
An extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, but also from legislative documents, manuals and books.
Results
There are currently no specific laws regulating PAS in European countries. According to Article 10.2 of the Spanish Constitution, norms related to fundamental rights shall be interpreted according to the Universal Declaration of Human Rights. As a direct consequence of the chronic psychological stresses experienced by children, adaptive disorders may appear, often characterised by symptoms of anxiety and depression. In addition, a multitude of neuropsychological consequences have been observed not only in the affected child, but also in the adult he or she will become.
Conclusions
Currently, there is a fervent debate about the validity and recognition of PAS as a diagnostic entity, spanning different disciplines, ranging from health to social and legal. In Europe, professionals in the scientific field have not reached an agreement regarding the approval of PAS. On the one hand, there are those for whom PAS is a verified phenomenon; on the other hand, there are those who flatly reject the existence of this phenomenon. The latter consider PAS an unscientific construct, referring to it as “court syndrome” or “patriarchal alienation syndrome”.

In 2018, the Pharmacological Risk Assessment Committee alerted to a potential relationship between accumulated hydrochlorothiazide dosage and the risk of non-melanoma skin cancer. To study this ...relationship we used data from the Spanish Pharmacovigilance System for Medicinal Products of Human Use.
Following a case search for every thiazide potentially associated with (SMQ/MedDRA) "Malignant Skin Neoplasms and not Otherwise Specified Skin Neoplasms", a series of disproportionality analyses were conducted by estimating the reporting odds ratio (95% confidence interval). Registered adverse drug reactions and disproportionality through the reported odds ratio were the main outcome measures.
For basal cell carcinoma, reporting odds ratio was 4.8 (2.2 - 10.7); squamous cell carcinoma 3.2 (0.9 - 10.5); malignant melanoma, 0.8 (0.2 - 3.5). We found both disproportionality and association between hydrochlorothiazide and basal cell carcinoma, but none of these were found regarding malignant skin melanoma. In the case of squamous cell carcinoma, the lower confidence interval limit was below 1, thus the disproportionality value was not statistically significant. The accumulated hydrochlorothiazide dose was 36,714 mg for basal cell carcinoma; 98,288 mg for squamous cell carcinoma; and 38,444 mg for malignant melanoma.
The results in Spain, where sun exposure is significant, are consistent with the data in the Pharmacological Risk Assessment Committee's alert, which were obtained in Denmark for both basal cell carcinoma and malignant melanoma. However, the results for squamous cell carcinoma did not reach statistical significance, although the reporting odds ratio value suggested a potential relationship between hydrochlorothiazide and squamous cell carcinoma.
Introduction
CD is characterized by at least three features: its duration is prolonged, it does not resolve spontaneously and it is rarely completely cured. Approximately 10-15% of young people have ...CD. Adolescents with CD often have emotional and behavioral problems.
Objectives
To assess risk factors, derived psychiatric pathologies and coping strategies for a CD diagnosis in adolescence.
Methods
An extensive literature review was carried out on the subject in question, extracting information mainly from scientific articles, manuals and books.
Results
The main risk factors are those related with the CD in question, physical sequelae, the need for long-term hospital admissions or the use of drugs whose side effects include affective or behavioral symptoms; those related to the personality traits of the affected child or adolescent. In addition, as far as the family is concerned, the presence of a low level of education, lack of support or communication, as well as the presence of psychiatric disorders or serious medical conditions in parents. Among the most frequent psychiatric disorders associated with CD are affective and anxiety disorders, adaptive disorders, somatoform disorders, eating disorders and behavioral disorders. Whatever the CD is, it generates high levels of stress and uncertainty in the patient and family, which must be dealt together from a flexible perspective, allowing child or adolescent to adapt to the changes, reorganize and facing them with adaptive patterns of behavior. For this, it will be essential to have adequate social and family support with relational style based on communication, trust and acceptance.
Conclusions
In general, both adolescents with CD and their families have an adequate capacity to adapt to the repercussions and effects derived from the disease. Nevertheless, in case of possible emotional difficulties that may appear, a comprehensive and individualized approach to these adolescents and their families is necessary to provide them resources and coping strategies in different areas and contexts in which the disease debuts.The comprehensive therapeutic approach will consist of interventions at the individual and family level. Among the main objectives of these interventions are to achieve acceptance and adaptation to CD provinding adequate psychosocial support to enable them to cope with CD in the best possible way and to detect and address the emotional implications, even coexisting psychopathology.
