Driven by the rapid escalation of its utilization, as well as ramping commercialization, Internet of Things (IoT) devices increasingly face security threats. Apart from denial of service, privacy, and safety concerns, compromised devices can be used as enablers for committing a variety of crime and e-crime. Despite ongoing research and study, there remains a significant gap in the thorough analysis of security challenges, feasible solutions, and open secure problems for IoT. To bridge this gap, we provide a comprehensive overview of the state of the art in IoT security with a critical investigation-based approach. This includes a detailed analysis of vulnerabilities in IoT-based systems and potential attacks. We present a holistic review of the security properties required to be adopted by IoT devices, applications, and services to mitigate IoT vulnerabilities and, thus, successful attacks. Moreover, we identify challenges to the design of security protocols for IoT systems in which constituent devices vary markedly in capability (such as storage, computation speed, hardware architecture, and communication interfaces). Next, we review existing research and feasible solutions for IoT security. We highlight a set of open problems not yet addressed among existing security solutions. We provide a set of new perspectives for future research on such issues including secure service discovery, on-device credential security, and network anomaly detection. We also provide directions for designing a forensic investigation framework for IoT infrastructures to inspect relevant criminal cases, execute a cyber forensic process, and determine the facts about a given incident. This framework offers a means to better capture information on successful attacks as part of a feedback mechanism to thwart future vulnerabilities and threats. This systematic holistic review will both inform on current challenges in IoT security and ideally motivate their future resolution. [ABSTRACT FROM AUTHOR]

New Materialism examines the role of subjects and objects in an environment shaped by new technologies. Based on these observations and considerations, the aim was to develop a new conception of materiality in the dynamic interplay of signifying processes and material structures. In a twenty-first-century world, where the points of interaction between humans and modern technological devices are steadily increasing, this approach becomes even more relevant. From a legal perspective, however, it becomes clear that this interplay between humans and processes has only been inadequately traced so far. In order to redress this dissatisfying situation, what is needed is a contemporary law that not only recognizes new subjects as such, but also understands new processes and roles. The aim of the present paper is thus to trace these processes between subjects and objects. In a second step, the aim is to build on the theory of New Materialism to make these insights workable for intellectual property law. [ABSTRACT FROM AUTHOR]

Human amniotic membranes (hAMs) are extraembryonic tissues currently employed in the treatment of many ocular and systemic diseases. Several reports indicate that hAMs can suppress the signaling pathway of tissue growth factor beta (TGF-β), a cytokine that plays a major role in the pathogenesis of proliferative vitreoretinopathy (PVR) through the induction of epithelial-mesenchymal transition (EMT) in exposed retinal pigmented epithelium (RPE) cells. The present study was conducted to evaluate the efficacy of a modified vitrectomy procedure (hAMP-V) involving the extensive coverage of exposed RPE with hAM patches to prevent postoperative PVR in a series of 15 cases of retinal detachment complicated by severe preoperatory PVR. The primary outcome was to assess the rate of successful retinal reattachment of a single hAMP-V procedure at 6 months from silicone oil removal. Secondary outcomes included the collection of intraoperative data concerning the quantity, size, and scope of hAM patches, and the assessment of postoperative improvements in mean LogMar BCVA at 3 and 6 months. Successful retinal reattachment was obtained in 14 out of 15 eyes (93.3%). Surgical failure due to major recurrence of PVR occurred in 1 out of 15 eyes (6.7%). Postoperative improvements in mean LogMar BCVA were statistically significant (p < 0.05, paired t-test). No intraoperative and postoperative adverse effects were reported. The study helped to refine the surgical technique while also offering cues for future improvements. [ABSTRACT FROM AUTHOR]

The aim of this, comparative in nature, study was to investigate the in vitro antioxidant activity of bee pollen, Quercus ilex honey, and saffron on the basis of the effective concentration of phytochemicals/antioxidants that could inhibit the DPPH free radical by 60% (EC60), using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) assay, in combination with regression analysis. Aqueous, ethanolic, and methanolic extracts of the aforementioned matrices of different concentrations were subjected to analysis. Results showed that the effective concentration of phytochemicals/antioxidants found in bee pollen, Quercus ilex honey and saffron could inhibit the DPPH free radical by 60% (EC60). The respective order of the significantly different (p < 0.05) antioxidant power was: Bee pollen > saffron > Quercus ilex honey. Results were further evaluated using standard gallic acid and quercetin. The use of a new index for the expression of the in vitro antioxidant power of natural products/foods may be of great importance for different bodies, concerning the producers, traders, consumers, and may be the solid basis for the development of numerous in vivo studies.

New Perspectives (NP) aims to prevent persistent criminal behavior. We examined the long-term effectiveness of NP and whether the effects were moderated by demographic and delinquency factors. At-risk youth aged 12 to 19 years were randomly assigned to the intervention group (NP, n = 47) or care as usual (CAU, n = 54). Official and self-report data were collected to assess recidivism. NP was not more effective in reducing delinquency levels and recidivism than CAU. Also, no moderator effects were found. The overall null effects are discussed, including further research and policy implications. [ABSTRACT FROM AUTHOR]

Children, teaching and modern science. In this paper, we propose to achieve some appropriate features of some concepts, to analyze some of the possibilities offered by the modern teaching, in particularly those in science and environmental protection. The teachers must constantly find new methods and learning techniques, which have to be interesting and attractive for the students. Science today became a necessity of knowledge, primarily through the vastness of the information provided the development of techniques and approach problems in an interdisciplinary manner. To let the young people's imagination "fly" to find new ideas, new perspectives, is a matter of modern didactics. Only this way we can change our conception and open to something new!

As the number of young and adult nulliparous cancer survivors is constantly increasing due to progress in the field of oncology, the adverse effect of the life saving cancer therapy on reproductive function is assuming greater importance. Appropriate strategies to spare fertility in all young cancer patients must be considered. Recent advances in assisted reproduction technology such as in-vitro fertilization (IVF), intra-cytoplasmic sperm injection (ICSI) and cryopreservation have revolutionized the options available to these patients for their fertility preservation. While sperm and embryo cryopreservation are now established procedures, oocyte (mature or immature) cryopreservation has limited application till date. Ovarian tissue cryopreservation although at present an experimental technique, is fast emerging out as the most promising future option for fertility preservation. There is need for the professionals dealing with young cancer patients to familiarize themselves with these developments and with the importance of describing and providing access to these options. All possible fertility preservation options should be offered and discussed before starting the therapy for cancer. A multidisciplinary approach involving a close liaison between oncology and assisted conception units is crucial for providing the proper guidance and support to the young vulnerable patients diagnosed with cancer and their families in deciding what is likely to be the most appropriate course of action for them.

For more than 10 years, we have been observing the Fayda Tijaniyya and its ramifications around the world. Starting in 2006 we have been conducting observations in Nigeria, Niger, Senegal and Mauritania. Between 2015 and 2017, we closely followed some developments of the Fayda in the French capital and in other European cities. In parallel to these field investigations, we have been interested in the new religious arrangements that are gradually emerging in the United Kingdom. More recently, in 2020, we benefited from a stay in the USA which allowed us to widen our observation framework. From there, we were able to collect empirical material consisting of several dozen interviews, direct observation notes, private and public documents (reports, administrative documents, correspondences, letters of recommendation, press articles, travel chronicles and private videos, among others). In the Fayda Ibrahimiyya, the global culture suggests an update of the mode of inheritance, but in addition it makes emerge a new framework of activity essentially composed of a device of formation with global character, of a hybrid diplomatic-religious space, finally of a humanitarian action which appears as a missionary presenza. We first show that the conjunction of these three registers of action has as a condition, a process of articulation and appropriation through which the actors of the Fayda manage to convince of the link of identity that prevails between their own history and that of the founder. The conclusion of the article is devoted to a critical discussion in which we postulate that the imagination of a homogeneous global community comes up against a form of local resistance that is a counterpoint and probably an anti-globalizing replica. The historical socio-anthropology of comprehensive inspiration that we favour allows us to finely approach the interdependencies between these three registers and the narrative elaborated locally by the supporters of this community. The paradigm of mobility in which we place the Fayda, allows us to grasp the scope of the globalization of practices and uses, as well as the tension that operates between a dynamic of continuity and a dynamic of rupture that crosses for some decades this religious community.
