Designs of low delay cosine modulated filter banks and subband amplifiers

This paper proposes a design of a low delay cosine modu-lated filter bank and subband amplifier coefficients for digi-tal audio hearing aids denoising applications. The objective of the design is to minimize the delay of the filter bank. Speci-fications on the maximum magnitude of both the real and the imaginary parts of the transfer function distortion and the aliasing distortion of the filter bank are imposed. Also, the constraint on the maximum absolute difference between the desirable magnitude square response and the designed mag-nitude square response of the prototype filter over both the passband and the stopband is considered. The subband am-plifier coefficients are designed based on a least squares training approach. The average mean square errors between the noisy samples and the clean samples is minimized. Com-puter numerical simulation results show that our proposed approach could significantly improve the signal-to-noise ratio of digital audio hearing aids

Enriching health-related research through glycobiological approaches

In the Laboratory of Mechanistic Glycobiology at Michigan Technological University, we have been working in four distinct but related areas. Our findings can significantly influence human health-related research. (1) We have documented a molecular strategy that can improve drug designing. (2) We have shown that the tumor-associated protein galectin-3 can create problems in cancer biomarker assays by hiding the biomarkers. (3) In another project, we reported that the role of galectin-3 in cancer could be more complicated than what is reported in the literature. (4) Our team also detected a novel natural product with anti-fungal and anti-cancer activities.https://digitalcommons.mtu.edu/techtalks/1012/thumbnail.jp

Qigong at Work: Where East Meets West

State of the Art Qigong is part of Traditional Chinese Medicine (TMC) and aims to balance body and mind. The roots of Qigong lie in China, where Confucian and Daoist scholars (500-400 B.C.) noted that one must learn to balance and relax one’s thoughts and emotions to avoid illness (Yang, 1997). In the Western world, Qigong is best known for its slow and coordinated movements. According to TCM, these movements will help regulate one’s ‘qi’, or life energy, through the body to improve the health and harmony of mind and body. During the practice of Qigong, one’s breathing, attention and movement are aligned. As such, Qigong is sometimes considered Mindfulness in movement (although there are many important differences). New perspectives / contributionsQigong has many positive outcomes on health and wellness. In both patient groups and healthy individuals, Qigong has been shown to improve psychological well-being, quality of life, immune function, balance and related risk-factors, and bone density (Jahnke et al., 2010). As such, Qigong offers a validated way to reduce the physical and mental activation that results from a person's work. While recent research has demonstrated how important it is to take short breaks at work, there is still little attention for Qigong exercises as a means to recover at work.Practical Implications In this presentation, we will explain and practice several Qigong exercises. These movements can be used at work (and at home) to recover from (hormonal) activation, ‘empty’ one’s head, and restore the body-mind balance. <br/

Adiabatic quantum computation and quantum phase transitions

We analyze the ground state entanglement in a quantum adiabatic evolution algorithm designed to solve the NP-complete Exact Cover problem. The entropy of entanglement seems to obey linear and universal scaling at the point where the mass gap becomes small, suggesting that the system passes near a quantum phase transition. Such a large scaling of entanglement suggests that the effective connectivity of the system diverges as the number of qubits goes to infinity and that this algorithm cannot be efficiently simulated by classical means. On the other hand, entanglement in Grover's algorithm is bounded by a constant.Comment: 5 pages, 4 figures, accepted for publication in PR

IFPOC Symposium:Discovering antecedents and consequences of complex change recipients' reactions to organizational change.

IFPOC symposium: Discovering antecedents and consequences of complex change recipients' reactions to organizational change Chairs: Maria Vakola (Athens University of Economics and Business) &amp; Karen Van Dam (Open University) Discussant: Mel Fugate (American University, Washington, D.C) State of the art Organisations are required to continuously change and develop but there is a high failure rate associated with change implementation success. In the past two decades, change researchers have started to investigate change recipients' reactions to change recognizing the crucial role of these reactions for successful change. This symposium aims at identifying and discussing the complex processes that underlie the relationships among antecedents, reactions and outcomes associated with organizational change. New perspective / contributions This symposium consists of five studies that extend our knowledge in the field by (i) providing an analysis of change recipients' reactions going beyond the dichotomous approaches (acceptance or resistance) (ii) revealing understudied antecedents-reactions and reactions-consequences patterns and relationships (iii) shedding light on the role of contextual factors i.e team climate and individual factors i.e emotion regulation on the adaptation to change. This symposium is based on a combination of both quantitative (i.e diary, survey) and qualitative (i.e interviews) research methodology. Research / practical implications This symposium aims to increase our understanding of the complex processes associated with change recipients' reactions to change. Discovering how these reactions are created and what are their results may reveal important contingencies that can explain how positive organizational outcomes during times of change can be stimulated which is beneficial for both researchers and practitioners
