Differences in agency? How adolescents from 18 countries perceive and cope with their futures

Abstract: This study investigated how N = 5,126 adolescents (mean age of 15 years) from 18 countries perceive and cope with future- and school-related stress. The adolescents completed the Problem Questionna...

Online speaker de-identification using voice transformation

Abstract: Speaker de-identification is the process by which speech is transformed in a way that the speaker identity is masked, while at the same time the transformed speech preserves acoustic information that contributes to the intelligibility, naturalness and clarity. Systems that perform speech de-identification could be used in voice driven applications (for example in call centres) where the speaker's identity has to be hidden. The paper describes the experiments we have performed in order to de-identify speech using GMM based voice transformation techniques and speaker identification using freely available tools. We propose a method by which speakers whose speech has not been used to build voice transformations (for training) can be efficiently de-identified online. The proposed method is evaluated using a speech database of read speech and a small set of speakers. The results we present show that the proposed de-identification method performs similarly as a closed-set de-identification procedure that requires previous enrolment and can efficiently be used for online speaker de-identification.

Surface-exposed Glycoproteins of Hyperthermophilic Sulfolobus solfataricus P2 Show a Common N-Glycosylation Profile

Abstract: Cell surface proteins of hyperthermophilic Archaea actively participate in intercellular communication, cellular uptake, and energy conversion to sustain survival strategies in extreme habitats. Surface (S)-layer glycoproteins, the major component of the S-layers in many archaeal species and the best-characterized prokaryotic glycoproteins, were shown to have a large structural diversity in their glycan compositions. In spite of this, knowledge on glycosylation of proteins other than S-layer proteins in Archaea is quite limited. Here, the N-glycosylation pattern of cell-surface-exposed proteins of Sulfolobus solfataricus P2 were analyzed by lectin affinity purification, HPAEC-PAD, and multiple mass spectrometry-based techniques. Detailed analysis of SSO1273, one of the most abundant ABC transporters present in the cell surface fraction of S. solfataricus, revealed a novel glycan structure composed of a branched sulfated heptasaccharide, Hex4(GlcNAc)2 plus sulfoquinovose where Hex is d-mannose and d-glucos...

Toward shipbuilding 4.0 - an industry 4.0 changing the face of the shipbuilding industry

Abstract: The Shipbuilding 4.0 at the principles of the Industry 4.0 will transform the design, manufacturing, operation, shipping, services, production systems, maintenance and value chains in the all aspects of the shipbuilding industry. Over the last few years, the fourth industrial revolution has spread in almost all industries. The whole world is talking about Industry 4.0 which has increased implication in the manufacturing process and the future of the work. The impact of the Shipbuilding 4.0 will be significant. In the past, shipbuilding industry where continuously improved with new machines, software and new implemented organizational restructuring. In today shipbuilding industry, there are three main problems that are considered ; production efficiency, the ship safety, cost efficiency and energy conservation and environmental protection. In order to create new value, the ship must become a Smart Ship capable of “thinking”, and to be produced in Smart Shipbuilding Process. The aim of this article is a review of the present academic and industrial progress of this new industrial revolution wave in the shipbuilding sector called Shipbuilding 4.0 (Shipping 4.0, Maritime 4.0, Shipyard 4.0). Reviewed publications were analyzed different topics and level of improvements in the industrial aspects of the society. The implementation of the Shipbuilding 4.0 in the shipbuilding industry, presents the future, creating new value in the process, creating new demands with reduction in production and operational cost while increasing production efficiency.
