We show that the "dark condensates" arise when excitons form a Bose-Einstein condensate in material with an indirect bandgap are not completely dark to optical emission. Rather, such states "leaky which emission is facilitated by many-body interactions. analyze properties of these leaky condensates context twisted bilayers transition metal dichalcogenides, host strongly interacting and bandgap....

Abstract Background The unbalanced gut microbiota, poorly ingested enriched fiber foods, leaky is connected to the progression of chronic kidney disease (CKD). translocates uremic toxins systemic circulation, promote inflammation, worsen CKD. Decreasing influx from may decrease So, we aimed evaluate effect probiotic and symbiotic supplementation on their role prevent CKD progression. Methods 48...

subsets of neurons, or they may have more of a scaffolding function. A scenario of multiple transsynaptic signaling proteins for different subsets of glutamate synapses is a rather daunting possibility that must now be considered. Such a possibility would allow for the extensive heterogeneity found in molecular composition of individual gluta-matergic postsynaptic specializations, depending on ...

We have examined the Ca2+ content and pathways of Ca2+ transport in frog rod outer segments using the Ca2+-indicating dye arsenazo III. The experiments employed suspensions of outer segments of truncated, but physiologically functional, frog rods (OS-IS), intact isolated outer segments (intact OS), and leaky outer segments (leaky OS with a plasma membrane leaky to small solutes, but with sealed...

In this paper, we study the transient behavior of a finite server (representing an ATM switch) which derives its input from a token leaky bucket with renewal cell arrival and deterministic token arrival distributions. We derive expressions for the transient and time averaged state probabilities, and transient and time averaged blocking probabilities for both the leaky bucket and server. We also...

In this paper, we study the problem of determining the capacity requirements for applications that require QoS guarantees. We consider three kinds of source models, Poisson based, On-Off based and leaky bucket filter based, and present explicit expressions capturing the required capacity. We compare the required capacity for average delay for these models with the required capacity for absolute...

When congestion occurs in VDSL networks, it will drop incoming frames because the buffer fills up frames until it overflows. In backpressure algorithm suitable for low traffic [1], it prevents buffer overflows. In backoff time in leaky bucket over traffic policing mechanism suitable for high traffic [2], Backoff time computations are wildly used in order to avoid the impact on the network perfo...

Compelling evidence indicates that alterations of intestinal homeostasis, such as " leaky " epithelial barrier and changes in microbiota composition, can be associated with pathological adaptations of brain functions (Carabotti et al., 2015). On the other hand, just as disrupted gut homeostasis affects the brain, the brain can also exert a profound influence on the intestine as indicated by the...
