Psychological profile of laryngectomized patients
Larynx cancer is one of the most susceptible form of cancer susceptible to induce alteration of the patient’s psychological profile due to the social role that the larynx has in communication. Oral communication is severely impaired even after voice rehabilitation of the laryngectomized patients, so that the social rehabilitation is somewhat not only a medical but also a social problem. The psychological profile of these patients is altered in a way that dealing with the disease is sometimes neglected and the interaction with the outside world in terms of oral communication is totally abandoned. The starting point for depression in these cases is the acknowledgement of the disease and is, in some cases, the entire medical environment. Facial scarring, the inability to verbally interact with other human, as well as the presence of the tracheostoma, are all deciding factors in the presence of a low self-esteem for these particular patients. Psychological counseling is a mandatory approach for laryngectomized patients, in order to improve their ability to cope with cancer and providing better recovery chances
SLIM : Scalable Linkage of Mobility Data
We present a scalable solution to link entities across mobility datasets using their spatio-temporal information. This is a fundamental problem in many applications such as linking user identities for security, understanding privacy limitations of location based services, or producing a unified dataset from multiple sources for urban planning. Such integrated datasets are also essential for service providers to optimise their services and improve business intelligence. In this paper, we first propose a mobility based representation and similarity computation for entities. An efficient matching process is then developed to identify the final linked pairs, with an automated mechanism to decide when to stop the linkage. We scale the process with a locality-sensitive hashing (LSH) based approach that significantly reduces candidate pairs for matching. To realize the effectiveness and efficiency of our techniques in practice, we introduce an algorithm called SLIM. In the experimental evaluation, SLIM outperforms the two existing state-of-the-art approaches in terms of precision and recall. Moreover, the LSH-based approach brings two to four orders of magnitude speedup
Space-Terrestrial Integrated Internet of Things: Challenges and Opportunities
Large geographical regions of our planet remain uncovered by terrestrial
network connections. Sparse and dense constellations of near-Earth orbit
satellites can bridge this gap by providing Internet of Things (IoT)
connectivity on a world-wide scale in a flexible and cost-effective manner.
This paper presents a novel space-terrestrial integrated IoT network
architecture spanning direct- and indirect-to-satellite access from IoT assets
on the surface. Framed on the identified requirements, we analyze NB-IoT and
LoRa/LoRaWAN features to put these technologies forward as appealing candidates
for future satellite IoT deployments. Finally, we list and discuss the key open
research challenges to be addressed in order to achieve a successful
space-terrestrial IoT integration
Licensing under Cournot vs Bertrand competition
In this paper we consider, on one hand, a differentiated Cournot
model, and, on the other hand, a differentiated Bertrand model,
when one of the firms engages in an R&D process that gives an
endogenous cost-reducing innovation. The aim of the present
paper is two-fold. The first is to study the licensing of the costreduction by a per-unit royalty and a fixed-fee in these Cournot
and Bertrand models. The second is to do a direct comparison
between Cournot model and Bertrand model. We analyse the
implications of these types of licensing contracts over the R&D
effort, the profits of the firms, the consumer surplus and the
social welfare. We show that some previous results for two-part
tariff licensing are not robust, in the sense that they can be not
true for just either a per-unit royalty contract or a fixed-fee contract. Furthermore, by using comparative static analysis, we conclude that the degree of the differentiation of the goods assumes
a great importance in the results. We also discuss the optimal
licensing, meaning that which licensing method is preferred, in
each of the duopoly models considered.info:eu-repo/semantics/publishedVersio
Pelvic floor disorders in gynecological malignancies. An overlooked problem?
Cervical, endometrial, ovarian, vulvar, and vaginal cancers affect women of a broad age spectrum. Many of these women are still sexually active when their cancer is diagnosed. Treatment options for gynecological malignancies, such as gynecological surgery, radiation, and chemotherapy, are proven risk factors for pelvic floor dysfunction. The prevalence of urinary incontinence, fecal incontinence, and sexual dysfunction before cancer treatment is still unclear. Hypotheses have been raised in the literature that these manifestations could represent early symptoms of pelvic cancers, but most remain overlooked even in cancer surviving patients.
The primary focus of therapy is always cancer eradication, but as oncological and surgical treatment options become more successful, the number of cancer survivors increases. The quality of life of patients with gynecological cancers often remains an underrated subject. Pelvic floor disorders are not consistently reported by patients and are frequently overlooked by many clinicians. In this brief review we discuss the importance of pelvic floor dysfunction in patients with gynecological malignant tumors
First-Class Approaches to Massive 2-Forms
Massive 2-forms are analyzed from the point of view of the Hamiltonian
quantization using the gauge-unfixing approach and respectively the
Batalin--Fradkin method. Both methods finally output the manifestly Lorentz
covariant path integral for 1- and 2-forms with Stueckelberg coupling.Comment: 14 page
