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...

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...

background: osteoarthritis is one of the most common diseases in synovial joints. dueto high loading forces during weight-bearing activities, the knee joint is prone to degenerative processes. this study aimed to compare the flexibility of muscles around the knee joint in patients with knee osteoarthritis with those of healthy individuals. methods: twenty-three women with bilateral knee osteoar...

man raises level of his needs by falsifying the nature and construction of the built spaces. by examining various aspects and complex dimensions of the human, variable and different needs can be clearly seen. therefore, an architectural construction, especially housing, should be able to set the access conditions to meet the highest level of the needs and achieve to the highest level of respons...
