There are non–vanishing price responses across different stocks in correlated financial markets. We further study this issue by performing different averages, which identify active and passive cross– responses. The two average cross–responses show different characteristic dependences on the time lag. The passive cross–response exhibits a shorter response period with sizeable volatilities, while...

A new approach is presented for determining the rigid regions in proteins and the flexible joints between them. The short-range forces in proteins are modeled as constraints and we use a recently developed formalism from graph theory to analyze flexibility in the bond network. Forces included in the analysis are the covalent bond-stretching and bond-bending forces, salt bridges, and hydrogen bo...

The mastery of two languages provides bilingual speakers with cognitive benefits over monolinguals, particularly on cognitive flexibility and selective attention. However, extant research is limited to comparisons between monolinguals and bilinguals at a single point in time. This study investigated whether growth in bilingual proficiency, as shown by an increased number of translation equivale...

I have just returned from NEHA’s 78th Annual Educational Conference (AEC) & Exhibition in Las Vegas, Nevada. This was one of our most successful AECs with over 1,000 attendees. The AEC’s President’s Banquet was attended by one of the largest crowds in recent memory. Additional tables were needed to seat everyone. The excitement of the crowd was amplifi ed by members of NEHA and the Internationa...

The abilities to either flexibly adjust behavior according to changing demands (cognitive flexibility) or to maintain it in the face of potential distractors (cognitive stability) are critical for adaptive behavior in many situations. Recently, a novel human paradigm has found individual differences of cognitive flexibility and stability to be related to common prefrontal networks. The aims of ...

We intended this Festschrift as a celebration of Dr. Stephen L. Wood’s 85th birthday. Sadly Dr. Wood past away a little before his 85th birthday thus this volume pays tribute to his life’s contribution to the study of bark and ambrosia beetles, which is summarized in the next article by Donald Bright. We arranged the volume geographically, starting with taxonomy of North American scolytines, fo...

In the context of the Markovian dynamical evolution in a nonstationary thermal bath, we construct a family of fluctuation relations for the entropy production that are not verified by the work performed on the system. We exhibit fluctuation relations, which are global versions either of the generalized fluctuation-dissipation theorem around a nonequilibrium diffusion or of the usual fluctuation...

in structural time seriesregression models, binary (classic) dummy variables are used to quantify the effects of economic structural breaks, changes or qualitative variables. the binary dummy variable can be challenged using this dummy variable in which 0 or 1 represent absence or presence of structural breaks(or changes), but presence of the structural breaks(or changes) may not have uniform e...

Research background: Flexibility has become a possible means for manufacturing companies to better compete in competitive markets. Furthermore, innovations are perceived as an important factor company strategy, which can differentiate the from competition. Purpose of article: This present study investigates problems cooperation flexibility and innovation among electrical engineering Czech Repub...
