Optimal distribution of the relaxation behavior of linear viscoelastic materials by the particle swarm optimization method applied to the problem of a twisting shaft
No full textWith rise of new manufacturing techniques such as additive manufacturing, there has been an increase in attention in designing components with distributed material properties. Utilizing the benefits of compliant mechanics, a strategic distribution of the relaxation behavior of linear viscoelastic materials was proposed.
The motivation of this research is to outline a mathematical/computational framework for the material distribution optimization problem of a linear viscoelastic material. The distribution of the relaxation behavior (coefficients of the Prony series expansion) across the system was obtained to achieve a target performance of the dynamic system by the particle swarm optimization (PSO) method. The (PSO) method was applied to a simple fixed shaft to demonstrate the improvement in the structural response of the system and convergence capability of the method.
While the simulations showed great improvements in the structural response, the lack of thorough search of the solution space to keep the computation time within a reasonable time frame meant that the method was unable to determine confidently the reaching of a global minimum. Additionally, the time for convergence increased with the increase of the number of nodes that were optimized.
In order to confidently reach the global minimum within a reasonable time frame, the computational efficiency of the PSO method must be improved such that the particles can thoroughly search the entire solution space. Additionally, the inclusion of additional constraints to ensure the continuity of the moduli across neighboring nodes must be done for the actual construction of the design.Submission original under an indefinite embargo labeled 'Open Access'.

Neurobehavioral mechanisms of social cognition and emotion regulation: A behavioral and functional brain imaging approach
No full textThe ability to process relevant social and emotional information while inhibiting the impact of unwanted negative one is critical to everyday functioning and well-being. Deficits in these processes, related to social cognition and emotion regulation, are oftentimes a hallmark of psychopathological conditions. Gaining a comprehensive understanding of the neurobehavioral mechanisms associated with these socioemotional processes would provide unique insights into the factors that may render individuals susceptible to or resilient against socioemotional distress. Despite significant advances in cognitive neuroscience, however, a comprehensive approach to investigate the mechanisms of socioemotional functioning is still scarce. Therefore, there is a need to capitalize on a broad set of approaches for the examination of socioemotional factors at multiple levels (i.e., brain function, behavior, and individual differences), in order to better understand the interplay of emotion and cognition with increased ecological validity. These issues were investigated using a multi-method approach involving functional brain imaging (functional magnetic resonance imaging, electroencephalography) in conjunction with behavioral tasks (social evaluation, emotion regulation, episodic memory), and measures of individual differences. Such an approach is essential to elucidate the mechanisms of socioemotional functioning, which may inform the development of novel theoretical frameworks that will lead to the design of assessment tools and interventions that promote social and emotional well-being.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01The student, Yuta Katsumi, accepted the attached license on 2019-04-19 at 11:10.The student, Yuta Katsumi, submitted this Dissertation for approval on 2019-04-19 at 11:11.This Dissertation was approved for publication on 2019-04-19 at 12:08.DSpace SAF Submission Ingestion Package generated from Vireo submission #13625 on 2019-08-22 at 16:21:24Made available in DSpace on 2019-08-23T20:47:24Z (GMT).

Neural signatures of ethnic in-group bias in observing dynamic social interactions
No full textDespite evidence for the role of nonverbal communication in the evaluation of social interactions, little is known about the mechanisms through which nonverbal behaviors of individuals of different ethnic groups influence such evaluations. Here, Caucasian participants underwent fMRI recording while observing social interactions with ethnically in-group and out-group members displaying approach and avoidance behaviors. Each behavior was preceded or not by a handshake, and was followed by participants’ ratings of the behavior. Brain imaging assessments identified evidence for ethnic in-group biases in evaluating specific nonverbal behaviors, in the absence of differences in the explicit behavioral ratings. First, the amygdala and dorso-medial prefrontal cortex showed sensitivity to in-group approach behaviors relative to control, and positive associations with the ratings for in-group approach behaviors. Second, enhanced functional connectivity between the amygdala and dorso-medial prefrontal cortex further clarified the mechanisms involved in the processing of in-group approach behaviors. Third, the posterior superior temporal sulcus and nucleus accumbens showed sensitivity to in-group handshakes, which was also linked to the positive impact of handshakes on in-group evaluations. Overall, these findings shed light on the mechanisms underlying intergroup social evaluations, and provide evidence for the neural signatures of ethnic in-group biases to approach and expected greeting behaviors.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2017-08-01The student, Yuta Katsumi, accepted the attached license on 2015-07-20 at 15:26.The student, Yuta Katsumi, submitted this Thesis for approval on 2015-07-20 at 21:02.This Thesis was approved for publication on 2015-07-21 at 08:54.DSpace SAF Submission Ingestion Package generated from Vireo submission #8570 on 2015-09-29 at 15:06:37Made available in DSpace on 2015-09-29T21:08:17Z (GMT).

Metal-Containing Schiff Base/Sulfoxide Ligands for Pd(II)-Catalyzed Asymmetric Allylic C-H Aminations
No full textMetal-containing Schiff base/sulfoxides were developed as chiral ligands for Pd(II)-catalyzed asymmetric intramolecular allylic C-H amination reactions. The use of metal-containing Schiff base ligands allows tuning the selectivity and reactivity of the Pd(II)-catalyst, whereby a Schiff base-Cu(II)/sulfoxide ligand in combination with Pd(OAc)(2) showed the best performance. Both internal and terminal alkenes were applicable, and the C-H amination products were obtained in up to 91:9 er

No full text/Chiral Carboxylic Acid‐Catalyzed C−H Alkylation/Cyclization
No full textSulfondiimines are diaza-analogues of sulfones with a chiral sulfur center. Compared to sulfones and sulfoximines, their synthesis and transformations have so far been studied to a lesser extent. Here, we report the enantioselective synthesis of 1,2-benzothiazine 1-imines, i.e., cyclic sulfondiimine derivatives from sulfondiimines and sulfoxonium ylides via C-H alkylation/cyclization reactions. The combination of [Ru(p-cymene)Cl-2](2) and a newly developed chiral spiro carboxylic acid is key to achieving high enantioselectivity
Stylops borcherti Luna de Carvalho 1974
No full textStylops borcherti Luna de Carvalho, 1974, stat. restit. Stylops borcherti Luna de Carvalho, 1974: 349, F. Type locality: Spain, Madrid, Alcalá de Henares. Host. Andrena (Melandrena) albopunctata (Rossi, 1792) (LUNA DE CARVALHO 1974). Note. This name is possibly a synonym, but it is unclear whether it belongs to S. melittae or S. ater, both known from the subgenus Melandrena in Europe. The latter species was used for comparison to S. borcherti by the original author, but we expect rather synonymy with S. melittae because S. melittae is known to occur in Spain, whereas S. ater is not (LUNA DE CARVALHO 1974). No DNA sequence is known for Stylops from this host species. The status of this species is restituted for the time being until its status is clarified using integrative taxonomy or from the study of the type material.Published as part of Straka, Jakub, Jůzová, Kateřina & Nakase, Yuta, 2015, Nomenclature and taxonomy of the genus Stylops (Strepsiptera): an annotated preliminary world checklist, pp. 305-332 in Acta Entomologica Musei Nationalis Pragae 55 (1) on page 311, DOI: 10.5281/zenodo.530438
