The majority of previous quasi-static tests on disproportionate collapse simulated the column removal through applying concentrated load/displacement top removed until failure. However, uniformly distributed service load always exists frames. Therefore, to reflect actual condition more accurately, should be applied along beams first. Then, temporary support is gradually simulate process removal...

Researchers awarded a considerable attention to progressive collapse analysis in recent years avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established base deal with such catastrophic failure. For multi-story building, these proposed column removal scenario which one more columns different locations should be removed from structure. Then, re...

In the not so distant future, we envisage an Internet where the biggest share of capacity is used by streaming applications. To avoid congestion collapse from unresponsive flows calls for a robust and ubiquitous end-to-end multimedia congestion control mechanism, such as TCP-friendly rate control (TFRC), which provides fair sharing with the other Internet traffic. This paper therefore analyses ...

In this paper, we study the response of 2D framed structures made of rectangular cells, to the sudden removal of columns. We employ a simulation algorithm based on the Discrete Element Method, where the structural elements are represented by elasto-plastic Euler Bernoulli beams with elongation-rotation failure threshold. The effect of structural cell slenderness and of topological hierarchy on ...

Introduction: Semaphorin 3A (Sema 3A) is a secreted protein, which plays an integral part in developing the nervous system. It has collapse activity on the growth cone of dorsal root ganglia. After the development of the nervous system, Sema 3A expression decreases. Neuropilin 1 is a membrane receptor of Sema 3A. When semaphorin binds to neuropilin 1, the recruitment of oligodendrocyte precurso...

Abstract Indicative and subjunctive conditionals are in non-complimentary distribution: there conversational contexts at which both licensed (Stalnaker 1975; Karttunen Peters 1979; von Fintel 1998). This means we can ask an important, but under-explored, question: license both, what relations hold between the two? In this paper, I’ll argue for initially surprising conclusion: when attention is ...

The significance of the "kink" occurring in the early portion of the forced expiratory spirogram of some patients with obstructed airflow was investigated in 153 patients with chronic obstructive pulmonary disease or asthma. The kink, which is presumably due to airway collapse, is facilitated by the presence of emphysema, which results in loss of elastic recoil, a positive pleural pressure, hig...
