Corner Localization In Digital Images Based On Radon Transform, Xuguang Wang, Zhang Qin, Su Jie

Journal of System Simulation

Abstract: Location accuracy is one of the key indexes of measuring the performance of feature point.. High location accuracy feature point detection has important implications for the applications such as 3D reconstruction, motion estimation, target tracking and recognition, image registration, etc. A corner location algorithm based on Radon transform is proposed.Edge binary images are obtained with traditional method first, ideal straight lines and curves are extracted then, potential corner locations are calculated next, fake corners are rejected finally. Experimental results on both simulation and real images show that, this method performs better than the existing methods on interest point localization …

Prosocial Leadership: The Transformative Power Of Others Directed Leadership Behavior, Timothy G. Ewest

Journal of Research Initiatives

This paper seeks to provide an understanding of the prosocial leadership development process as defined by Ewest (2018), and how it acts to personal flourishing. To this end, this paper will provide an understanding of personal flourishing as discussed by Rogers (1959), positive psychology framed by Mackie, (2017) and then considers the emerging positive theories of leadership as discussed by Ewest (2018b). Finally, the paper will resolve by considering prosocial values, and specifically the prosocial leadership development process as posited by Ewest (2018), including the four steps in the process and possible benefits from becoming a prosocial leader.

The BGM program combines bilingual positive suggestions with guided meditation and relaxing background music. Results indicated that the BGM may reduce anxiety and can improve academic performance.

Distributed Leadership: Theorizing A Mindful Engagement Component, Arij Rached, Simone Elias

Journal of Research Initiatives

The distributive leader cannot influence organizational performance without taking into consideration the capabilities of team members to achieve a common goal (McIntyre, 2003; Harris, 2003). To leverage the capabilities of teams, distributive leaders need to be mindfully attentive in establishing a collective interpretation of the current organizational situation. However, establishing a collective interpretation may not be effective if distributive leaders do not initially consider the importance of creating group learning environments to engage diverse group members (Ashford & DeRue, 2012). The purpose of this integrative literature review is to explore theoretical and empirical research examining the potential of mindful engagement …

Domination Of European Culture In All Over The World, Md. Ruhul Amin

Journal of Research Initiatives

European colonialism is an extremely controversial affair in world history that is also discussed today. This paper explores the influence of these happenings as the world incorporates the culture of European in every step of life. Europe dominated almost the entire world and its people were leaders in science and technology. European languages, literature, and culture spread all over the globe. Decisions in Europe largely determined global events for centuries. The other continents did not approach European power until after World War 1 or World War 2. Europe consisted of constantly competing nations, and this competition spurred development. Europe achieved …

This study focuses on the position of mother languages in Greek education at the level of educational policy, demonstrating the necessity of their further emergence based on modern scientific findings on the benefits of bilingualism. Through an effort to record a set of obstacles that make it difficult for them to join the curriculum, a framework is proposed to be used for the language repertoire of all pupils, so that their rights are respected in practice and their linguistic richness serves as a source of enrichment for the whole population. The implementation of practices that could enhance the free and …

Leadership Theories And United States Demographic Shifts: Responsiveness In The Workplace, Sherry H. Latten, Jonathan Perez

Journal of Research Initiatives

As the United States becomes increasingly more diverse, it is imperative that organizations consider the implications of their leadership pipeline. Given the differences that can exist by social identity groups in experiences, values, interests, and communications, it raises a question about the responsiveness of current leadership theories to the changing demographics. This article explores the responsiveness of transformational leadership, authentic leadership, and leader-member exchange (LMX) theory to the demographic changes as a means of helping organizations consider how existing leadership norms and theories need to be expanded to encompass the future population of leaders across race, sex, and age.

Optical interrogation of voltage in deep brain locations with cellular resolution would be immensely useful for understanding how neuronal circuits process information. Here, we report ASAP3, a genetically encoded voltage indicator with 51% fluorescence modulation by physiological voltages, submillisecond activation kinetics, and full responsivity under two-photon excitation. We also introduce an ultrafast local volume excitation (ULoVE) method for kilohertz-rate two-photon sampling in vivo with increased stability and sensitivity. Combining a soma-targeted ASAP3 variant and ULoVE, we show single-trial tracking of spikes and subthreshold events for minutes in deep locations, with subcellular resolution and with repeated sampling over days. In the …

The Optimized Synthesis Of Copper Nanowire For High-Quality And Fabrication Of Core-Shell Nanowire, Suhyun Lee

Dissertations and Theses

Flexible electronics are the promising technology for prospective application in foldable phones. Currently, indium tin oxide (ITO) has been widely used for electronic devices including flat-panel display. However, it is brittle and expensive. Metal nanowires are considered as alternative materials. Among various metal nanowires, copper nanowires are attractive because of its high electrical conductivity, better flexibility, and low cost compared with ITO. However, copper nanowires are very prone to oxidize, which causes subsequent degradation of electrical conductivity. Due to this oxidation issue, core-shell structure nanowires, which are formed silver shell having high conductivity and low resistivity on the surfaces of …

Distinct Vip And Pacap Functions In The Distal Nerve Stump During Peripheral Nerve Regeneration, Patricia K. Woodley, Qing Min, Yankun Li, Nina F. Mulvey, David B. Parkinson, Xin Peng Dun

Peninsula Medical School

Vasoactive Intestinal Peptide (VIP) and Pituitary Adenylyl Cyclase Activating Peptide (PACAP) are regeneration-associated neuropeptides, which are up-regulated by neurons following peripheral nerve injury. So far, they have only been studied for their roles as autocrine signals for both neuronal survival and axon outgrowth during peripheral nerve regeneration. In this report, we examined VIP and PACAP’s paracrine effects on Schwann cells and macrophages in the distal nerve stump during peripheral nerve regeneration. We show that VPAC1, VPAC2, and PAC1 are all up-regulated in the mouse distal nerve following peripheral nerve injury and are highly expressed in Schwann cells and macrophages within …
