The purpose of this study was to determine the effectiveness of a systematic, explicit, intensive Tier 3 (tertiary) intervention on the mathematics performance of students in second grade with severe mathematics difficulties. A multiple-baseline design across groups of participants showed improved mathematics performance on number and operations concepts and procedures, which are the foundation...

In this paper we study the effects of data relaying in wireless sensor networks (WSNets) under QoS constraints with two different strategies. In the first, data packets originating from the same source are sent to the base station possibly along several different paths, while in the second, exactly one path is used for this purpose. The two strategies correspond to splitting and not splitting r...

In this paper, we investigate the per-tier outage probability of multiuser multiple-input multiple-output (MU-MIMO) transmissions in heterogeneous networks (HetNets) with joint interference constraint. tier cellular cell, user equipment (UE) is required to report measured channel information and base station (BS) adopts ZF-based precoding MU-MIMO transmission achieve diversity gain. With constr...

Automated computer-aided detection (CADe) has been an important tool in clinical practice and research. State-of-the-art methods often show high sensitivities at the cost of high false-positives (FP) per patient rates. We design a two-tiered coarse-to-fine cascade framework that first operates a candidate generation system at sensitivities  ∼ 100% of but at high FP levels. By leveraging existin...

User analysis job demands can exceed available computing resources, especially before major conferences. ATLAS physics results can potentially be slowed down due to the lack of resources. For these reasons, cloud research and development activities are now included in the skeleton of the ATLAS computing model, which has been extended by using resources from commercial and private cloud provider...

Most HIV-1 vaccines elicit neutralizing antibodies that are active against highly sensitive (tier-1) viruses or rare cases of vaccine-matched neutralization-resistant (tier-2) viruses, but no vaccine has induced antibodies that can broadly neutralize heterologous tier-2 viruses. In this study, we isolated antibodies from an HIV-1-infected individual that targeted the gp41 membrane-proximal exte...

Today ecotoxicological evaluations of surface water quality are either based on field surveys or online biomonitoring, whereas the ecotoxicological quality of wastewater is mostly determined with standardised acute toxicity tests. In this paper we present a concept for the ecotoxicological evaluation of surface waters, where mainly in vitro tests are used for the screening of water samples, pre...

This research adopts Barua’s [1] three-tier Business Value Complementarity (BVC) model to study the performance of telephone companies (Telcos). Our study integrates constructs such as spending on telecommunication infrastructure, assets, plant investment, and operating expenses into the bottom tier of BVC. The second layer incorporates measures of operational efficiency and customer satisfacti...
