Dietary restriction (DR) results in a robust increase in lifespan while maintaining the physiology of much younger animals in a wide range of species. Here, we examine the role of drr-2, a DR-responsive gene recently identified, in determining the longevity of Caenorhabditis elegans. Inhibition of drr-2 has been shown to increase longevity. However, the molecular mechanisms by which drr-2 influ...

O wning Natural resources has been beneficial for some Countries, but hurtful for some others. Optimum management of natural resources in the former group has enhanced economic growth, bad governance, however, has led to Dutch Disease in the latter group. Bad governance in Iran has created Dutch Disease, Rentier State, and Resource Curse, DRR as a characteristic triangle. As the Iran...

THE CONSULTANT PHARMACIST JUNE 2003 VOL. 18, NO. 6 Although it has been a core component of consultant pharmacy practice for more than 30 years, drug regimen review (DRR) continues to evolve to accommodate many new additions to the increasingly complex medication armamentarium, and the changing needs of long-term care patient populations. In the first article in this three-part series, we explo...

In the emerging high-speed packet-switched networks, fair packet scheduling algorithms in switches and routers will form an important component of the mechanisms that seek to satisfy the Quality of Service (QoS) requirements of various applications. The latency bound of a scheduling discipline is an important QoS parameter, especially for real-time playback applications. Frame-based schedulers ...

Reward-risk ratio (RR) is a very important stock market definition. In order to capture the situation that the investor does not have complete information on the distribution of the underlying uncertainty, people extend RR model to distributionally robust reward-risk ratio (DRR) model. In this paper, we study the DRR problem where the ambiguity on the distributions is defined through Wassertein...

This paper proposes a practical approach to estimate the direct-toreverberant energy ratio (DRR) using a spherical microphone array without having knowledge of the source signal. We base our estimation on a theoretical relationship between the DRR and the coherence estimation function between coincident pressure and particle velocity. We discuss the proposed method’s ability to estimate the DRR...

Delay is an important Quality of Service (QoS) parameter. A significant part of an end-to-end delay of a data flow is latency – the delay induced by scheduling algorithms in network devices. In this paper we present a latency analysis of a Deficit Round-Robin (DRR) scheduler. We correct inaccuracies and deficiencies of the DRR latency analysis detected in works of other authors. We derive a new...

In the emerging high-speed packet-switched networks, packet scheduling algorithms used in the switches and routers will play a critical role in satisfying the Quality of Service (QoS) requirements of various applications. The latency bound of a scheduling discipline is an important QoS parameter, especially for real-time playback applications. Frame-based schedulers such as Deficit Round Robin ...

We address the measurement of reverberation in terms of the (DRR) in the context of the assessment of dereverberation algorithms for which we wish to quantify the level of reverberation before and after processing. The DRR is normally calculated from the impulse response of the reverberating system. However, several important dereverberation algorithms involve nonlinear and/or time-varying proc...

Infrastructure facilities need to be planned and constructed in such a way not only to change the vulnerable conditions of the infrastructure facility itself but also the society, the economy and the environment. Literature emphasises that integration of disaster risk reduction (DRR) to planning processes is a key to reduce natural disaster losses, boost socio-economic development needs and ens...
