Abstract

The future 6G network is envisioned to be AI-native, and as such, ML models will be pervasive in support of optimizing performance, reducing energy consumption, and in coping with increasing complexity and heterogeneity. A key challenge is automating the process of finding optimal model architectures satisfying stringent requirements stemming from varying tasks, dynamicity and available resources in the infrastructure and deployment positions. In this paper, we describe and review the state-of-the-art in Neural Architecture Search and Transfer Learning and their applicability in networking. Further, we identify open research challenges and set directions with a specific focus on three main requirements with elements unique to the future network, namely combining NAS and TL, multi-objective search, and tabular data. Finally, we outline and discuss both near-term and long-term work ahead.

Abstract

Deployment of real-time ML services on warehouse-scale infrastructures is on the increase. Therefore, decreasing latency and increasing throughput of deep neural network (DNN) inference applications that empower those services have attracted attention from both academia and industry. A common solution to address this challenge is leveraging hardware accelerators such as GPUs. To improve the inference throughput of DNNs deployed on GPU accelerators, two common approaches are employed: Batching and Multi-Tenancy. Our preliminary experiments show that the effect of these approaches on the throughput depends on the DNN architecture. Taking this observation into account, we design and implement DNNScaler which aims to maximize the throughput of interactive AI-powered services while meeting their latency requirements. DNNScaler first detects the suitable approach (Batching or Multi-Tenancy) that would be most beneficial for a DNN regarding throughput improvement. Then, it adjusts the control knob of the detected approach (batch size for Batching and number of co-located instances for Multi-Tenancy) to maintain the latency while increasing the throughput. Conducting an extensive set of experiments using well-known DNNs from a variety of domains, several popular datasets, and a cutting-edge GPU, the results indicate that DNNScaler can improve the throughput by up to 14x (218% on average) compared with the previously proposed approach, while meeting the latency requirements of the services.

Abstract

A retrospective view of exaltation of refraction observed for many unsaturated and aromatic compounds demonstrates that this physical phenomenon is undeservedly considered only as a qualitative measure of conjugation. This mini-review discusses numerous papers by the author that have been published earlier in inaccessible periodicals and collections of scientific papers. Using a great number of illustrations, the author shows that this parameter can be successfully used for quantitative estimate of resonance effects in organic and polymer chemistry. The methods for derivation of strictly additive atomic and group refraction constants are described; these constants were subsequently used as a tool that allowed quantitative estimation of resonance effects in mono-, di-, tri- and polyalkylbenzenes, alkylnaphthalenes, some alkyl derivatives of unsaturated hydrocarbons. These effects cause strictly fixed increase in refraction of carbon atoms in different structural modifications (graphene, fullerene, diamond) and in polycyclic aromatic hydrocarbons. The relevant results regarding quantitative estimation of degree of steric inhibition of resonance in sterically hindered ortho-dialkylbenzenes, 1,2,3- trialkyl-, 1,2,3,4-tetraalkyl-, and 1,2,3,4,5-polyalkylbenzenes accumulated by the author are summarized.

Abstract

Background: Daily toothbrushing and flossing are easy, effective and low-cost practices for removing the microbial dental plaque, which is an important factor in the development of caries and periodontal disease. Aim: The objective of this study is evaluation of oral health behaviors in a group of students from an Iranian university . Materials and Methods: This descriptive analytical cross-sectional study was carried out on 1736 Iranian students (1230 non-medical sciences students and 506 medical sciences students). Subjects were randomly selected. The students were asked to fill out a self-completion questionnaire about daily oral health behavior. Statistical Analysis Used: The chi-square test was used for evaluation of oral health behaviors and relationship between students′ oral hygiene behavior and educational levels. Results : There was no difference between the frequencies of tooth brushing in the students of two universities. Medical sciences students used dental floss more than non-medical sciences students, which was a significant difference ( P = 0.000). There was no significant difference in toothbrushing frequency among the students with different levels of education. But the students of doctorate and masters degrees used dental floss significantly more than those of bachelor or associate degrees ( P = 0.000). Conclusions: This study showed that the level of self oral care among Iranian students is at a lower level than in industrialized countries.

Abstract

In the framework of climate change, and especially sea level rise, the Polder2C’s project has been set up to improve, among others, knowledge of external erosion processes on seashore earth dikes. Within the project, overflow, overtopping and breaching in-situ tests are carried out in the Hedwige- and Prosperpolder, while numerical models are set up to improve technical analysis of testing results. This paper describes blind predictions of water depth and flow velocity on the slope of a levee during an overflow event prior, before the test is conducted, using a range of different state-of-the-art numerical models. This model predictions were performed by several partners of the Polder2C’s project. No in advance calibration of the numerical models was carried out, all models considered the same levee geometry, roughness of the grass cover layer and upstream boundary conditions. The aim of the comparison is to identify best numerical tools to predict flow pattern for different hydraulic loadings, since it takes part of the erosion process, which is to be analyzed as a second step. Homogeneous results have been found with the different deployed tools, with some spread partially linked to numerical uncertainties, and calculation methods. Next, numerical modelling steps within the project are calibration of the hydraulic models (e.g. the roughness of the grass cover layer) and modelling of the erosion process under calculated hydraulic loading conditions. In order to calculate the erosion of the cover layer, the computed erosion will be compared with the erosion measured during the field experiments within the coming years. This project is partly funded by the Interreg 2 Seas 2014-2020 programme, and
