The new generation WiFi (Widely Fidelity), which is called 802.11ac, has the goal of reaching at least 1 Gbps on bands below 6 GHz. This is why, the standard has been extended with new features at both PHYsical (PHY) and Medium Access Control (MAC) layers level. One of the key features of MAC layer is the ability of aggregating frames in order to reduce temporal overheads that significantly har...

Residual learning [6] with skip connections permits training ultra-deep neural networks and obtains superb performance. Building in this direction, DenseNets [7] proposed a dense connection structure where each layer is directly connected to all of its predecessors. The densely connected structure leads to better information flow and feature reuse. However, the overly dense skip connections als...

Porcine embryonic stem cells (pESCs) have become an advantageous experimental tool for developing therapeutic applications and producing transgenic animals. However, despite numerous reports of putative pESC lines, deriving validated pESC lines from embryos produced in vitro remains difficult. Here, we report that embryo aggregation was useful for deriving pESCs from in vitro-produced embryos. ...

The widespread deployment of various networking technologies, coupled with the exponential increase in enduser data demand, have led to the proliferation of multi-homed, or multi-interface enabled, devices. These trends drove researchers to investigate a wide spectrum of solutions, at different layers of the protocol stack, that utilize available interfaces in such devices by aggregating their ...

while ignoring income distribution and estimating aggregate demand generally leads to aggregation bias and thus, does not reflect households’ demand properly, yet aggregation bias is rarely considered in empirical demand studies and simply is ignored in most cases. the objective of the present study is to estimate aggregation bias in households’ demand for various types of meats and to evaluate...

protein aggregation is a serious problem for both biotechnology and cell biology. diseases such as prion misfolding, alzheimer’s, and other amyloidosis are phenomena for which protein aggregation in our living cells is of considerable relevance. human lysozyme has been shown to form amyloid fibrils in individuals suffering from nonneuropathic systemic amyloidosis, all of which have point mutati...

a series of novel 2-aminopyrimidine and 2-substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against adp and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. none of the compounds showed satisfactory activity against the aggregation induced by adp. however, satisfac...

in this work, we define a fuzzy soft set theory and its related properties. we then define fuzzy soft aggregation operator that allows constructing more efficient decision making method. finally, we give an example which shows that the method can be successfully applied to many problems that contain uncertainties.

The IEEE 802.11n standard is defined to achieve a high throughput at the MAC layer. This high throughput is accomplished via many enhancements in both the physical and MAC layers. A key enhancement introduced in the 802.11n standard is frame aggregation. Two types of aggregation defined by the 802.11n standard, aggregate MAC service data unit (A-MSDU) and aggregate MAC protocol data unit (A-MPD...

In wireless sensor networks source data must be routed by intermediate nodes to reach the sink. Data aggregation is an efficient method to decrease energy consumption in these networks. However, providing end to end data reliability is a major challenge when the network uses data aggregation, in this case, a packet loss can greatly affect final results. End to end reliability can be increased b...
