A need for evidence-based and multidisciplinary research to study the effects of the interaction of school environmental conditions on student achievement
With funding from the U.S. Environmental Protection Agency’s (EPA) Healthy Schools initiative, a research team from the University of Nebraska– Lincoln (UNL) is currently working on establishing how environmental conditions in K-12 school buildings impact student scholastic achievement. The objectives of the research project are: (1) to study comprehensively the impacts of a wide set of indoor environmental factors (including indoor air quality, thermal, lighting and acoustic conditions) on student achievement; (2) to investigate how these environmental conditions interact with each other to impact student achievement; (3) to rank order the environmental variables in terms of their relative impact on student achievement and (4) to determine how these effects vary with different demographic (e.g. socio-economic) groups
Draft Genome Sequence of Chromobacterium violaceum Strain CV017
We announce the draft genome sequence for Chromobacterium violaceum strain CV017, used as a model and tool to understand acyl-homoserine lactone-dependent quorum sensing. The assembly consists of 4,774,638-bp contained in 211 scaffolds
Antifungal Activity of Camptothecin, Trifolin, and Hyperoside Isolated from Camptotheca acuminate
Leaf spots and root rots are major fungal diseases in Camptotheca acuminata that limit cultivation of the plant for camptothecin (CPT), a promising anticancer and antiviral alkaloid. Bioassays showed that pure CPT and flavonoids (trifolin and hyperoside) isolated from Camptotheca effectively control fungal pathogens in vitro, including Alternaria alternata, Epicoccum nigrum, Pestalotia guepinii, Drechslera sp., and Fusarium avenaceum, although antifungal activity of these compounds in the plant is limited. CPT inhibited mycelial growth by approximately 50% (EC50) at 10-30 Ãg/mL and fully inhibited growth at 75-125 Ãg/mL. The flavonoids were less effective than CPT at 50 Ãg/mL, particularly within 20 days after treatment, but more effective at 100 or 150 Ãg/mL. CPT, trifolin, and hyperoside may serve as leads for the development of fungicides

GlucoSynth: Generating Differentially-Private Synthetic Glucose Traces
We focus on the problem of generating high-quality, private synthetic glucose
traces, a task generalizable to many other time series sources. Existing
methods for time series data synthesis, such as those using Generative
Adversarial Networks (GANs), are not able to capture the innate characteristics
of glucose data and cannot provide any formal privacy guarantees without
severely degrading the utility of the synthetic data. In this paper we present
GlucoSynth, a novel privacy-preserving GAN framework to generate synthetic
glucose traces. The core intuition behind our approach is to conserve
relationships amongst motifs (glucose events) within the traces, in addition to
temporal dynamics. Our framework incorporates differential privacy mechanisms
to provide strong formal privacy guarantees. We provide a comprehensive
evaluation on the real-world utility of the data using 1.2 million glucose
traces; GlucoSynth outperforms all previous methods in its ability to generate
high-quality synthetic glucose traces with strong privacy guarantees
On real-time optical subcarrier management in P2MP networks with mixed-strategy gaming
We developed a mixed-strategy gaming approach for distributed and real-time optical subscarrier management in point-to-multipoint networks, achieving traffic loss rates close to those by ILP-based centralized optimization.This work was supported in part by NSFC under Project 62201627, by the European Commission though the HORIZON SEASON (G.A. 101096120) projects, by the MICINN IBON (PID2020-114135RB-I00) project and from the ICREA institution.Peer ReviewedPostprint (author's final draft
