Reply to arXiv:2111.13357 ("The Quantum Eraser Non-Paradox'')
In a recent criticism (arXiv:2111.13357) of our paper arXiv:2111.09347,
Drezet argues that we have forgotten to consider superpositions of detector
eigenstates. However, such superpositions do not occur in the models our paper
is concerned with. We also note that no one has ever observed such detector
superpositions.Comment: 1 pages, no figure
Quantum Optics With Single Nanodiamonds Flying Over Gold Films: Towards A Robust Quantum Plasmonics
A nanodiamond (ND) hosting nitrogen-vacancy (NV) color centers is attached on
the apex of an optical tip for near-field microscopy. Its fluorescence is used
to launch surface plasmon-polaritons (SPPs) in a thin polycrystalline gold
film. It is shown that the quantum nature of the initial source of light is
preserved after conversion to SPPs. This opens the way to a deterministic
quantum plasmonics, where single SPPs can be injected at well-defined positions
in a plasmonic device produced by top-down approaches.Comment: 31st Int. Conf. Phys. Semiconductors, Zurich, July-August 201
Surface Plasmon-Polariton in X – Shaped Waveguides
A method of projection optical lithography to form X-shaped waveguides surface plasmon polaritons, (SPP) is proposed in current paper. A physical system based on point dipole approximation is taken as a theoretical basis for modeling of the SPP emergence processes. The possibility to control spreading of the SPP depending on the phase of the excitation of the optical signal is investigated
Sexual abuse characteristics in Santo André, São Paulo, Brazil: from victims to aggressors, from diagnosis to treatment
Introduction: Sexual violence against children and adolescents in Brazil is an underreported public health problem. Knowing the profile of the victims and the factors related to each case is a strategy for the development of more effective public policies.Objective: To describe the profile of children and adolescent victims of sexual abuse, characteristics of aggression and aggressors, consequences for victims, and legal actions related to sexual abuse.Methods: Sociodemographic characteristics of the victims were analyzed, as well as characteristics of the aggressors and aggression, and clinical, psychological, and legal aspects of 61 sexually abused patients admitted to the specialized outpatient clinic of the Network of Health for Violence and Sexual Abuse located in Santo André, São Paulo State, Brazil.Results: Victims had a mean age of 10.4 years, female (60.7%, n= 37), white (70.5%, n= 43), and admitted to the care network after of 72 hours of having been a victim of abuse (68.3%, n = 40). Most of the aggressions were by a sexual act (65.6%, n = 40) and by an individual known by the victim (72.1%, n= 44). As a result of sexual abuse, the children had a change in family composition (42.6%, n = 26), cognitive disturbances (34.4%, n= 21), emotional disturbances (83.6%, n= 51), and behavioral disorders (54.1%, n= 33). Two-thirds of the cases resulted in a police investigation, only 20% of the offenders were convicted.Conclusion: Girls suffer sexual abuse where the perpetrator is known and close to the family; they delay seeking health services and can present mental disorders related to those abuses, but the perpetrators remain unpunished in most cases

Forestry and Economic Development on the Oki Islands, Japan, PRP 196
The Oki Islands are composed of four inhabited islands (Dogo, Nishinoshima, Nakanoshima, and Chiburijima) and 38 uninhabited islands located 40 kilometers (24 miles) north of Japan’s Honshu Coast. In recent years, the islands have experienced a decrease in the population and changes in tourist preferences that have affected local business. In 2014, the town decided to reduce its reliance on imported diesel fuel for energy production and explore green energy options for meeting local demand. To respond to the changing economy of the islands, the local Oki Islands government, along with the Shimane Prefecture and federal governments, have formulated the Green Complex (GC) project (also known as Midori no Kombinat). This plan’s objective is to create a network of small- to medium-sized businesses on the island that will utilize the islands’ local biomass resources to develop the economy, create jobs, and reduce the island’s reliance on imported fossil fuels.
This report analyzes the availability of biomasses resources and how those resources can be utilized to enhance the quality of life on the islands. The research demonstrates that the GC project can generate employment on the islands and increase levels of economic activity. The study concludes that there is enough wood biomass to support green industries on the island; approximately 87 percent of Dogo Island is covered in forests which can support significant new industries using wood biomass as an input. The use of biomass on the island is more efficient than exporting the wood chips due to the cost of marine transport. Using the biomass for a large-scale power plant is economically feasible. Regarding pellet stoves, the study concluded that financial subsidies are necessary as a prerequisite to a viable industry, because pellet stoves are costlier for citizens than alternate stoves or maintaining existing equipment. Other opportunities exist for economic revitalization beyond the biomass industries, particularly in ecotourism. Complex and opaque ownership of land impedes the use of this resource. The final chapter reports recommendations regarding forest and ecotourism entrepreneurship.Government of Japan; Hiroshima University; Doshisha University of Kyoto; Institute for Innovation, Creativity and Capital (IC2).Public Affair
