Flood Risks of Cyber‐Physical Attacks in a Smart Storm Water System

The rise in smart water technologies has introduced new cybersecurity vulnerabilities for water infrastructures. However, the implications of cyber‐physical attacks on the systems like urban drainage systems remain underexplored. This research delves into this gap, introducing a method to quantify flood risks in the face of cyber‐physical threats. We apply this approach to a smart stormwater system—a real‐time controlled network of pond‐conduit configurations, fitted with water level detectors and gate regulators. Our focus is on a specific cyber‐physical threat: false data injection (FDI). In FDI attacks, adversaries introduce deceptive data that mimics legitimate system noises, evading detection. Our risk assessment incorporates factors like sensor noises and weather prediction uncertainties. Findings reveal that FDIs can amplify flood risks by feeding the control system false data, leading to erroneous outflow directives. Notably, FDI attacks can reshape flood risk dynamics across different storm intensities, accentuating flood risks during less severe but more frequent storms. This study offers valuable insights for strategizing investments in smart stormwater systems, keeping cyber‐physical threats in perspective. Furthermore, our risk quantification method can be extended to other water system networks, such as irrigation channels and multi‐reservoir systems, aiding in cyber‐defense planning. , Key Points We proposed a mathematical framework for evaluating flood risks of cyber‐physical attacks in a smart stormwater system False data injection can maliciously increase inflow and reduce the outflow of a targeted detention pond in a smart stormwater system Additional flood risks caused by false data injection are higher with smaller, more frequent storm

Evaluating the carbon footprint of the integrated DBD‐plasma bi‐reforming unit via laboratory scale experiments and scaled‐up process modeling

Catalytic dielectric barrier discharge (DBD) plasma reactor experiments were performed in a tubular glass reactor with a 2 mm gap at 550°C to facilitate the reaction kinetics of steam added dry reforming or bireforming. The best specific energy input obtained was 11.2 eV/molecule feed at CO 2 :CH 4 :H 2 O of 4.5:1:4.5 ratio and gas hour space velocity (GHSV) = 432 h −1 . This value was used to design a conceptual process and assess the environmental impact of methane steam reforming‐based H 2 production 18.4 kmol/h CO 2 emission processing into H 2 :CO = 2 syngas, with an emphasis on the carbon footprint

GRASP reconstruction amplified with view-sharing and KWIC filtering reduces underestimation of peak velocity in highly-accelerated real-time phase-contrast MRI: A preliminary evaluation in pediatric patients with congenital heart disease

Purpose To develop a highly‐accelerated, real‐time phase contrast (rtPC) MRI pulse sequence with 40 fps frame rate (25 ms effective temporal resolution). Methods Highly‐accelerated golden‐angle radial sparse parallel (GRASP) with over regularization may result in temporal blurring, which in turn causes underestimation of peak velocity. Thus, we amplified GRASP performance by synergistically combining view‐sharing (VS) and k ‐space weighted image contrast (KWIC) filtering. In 17 pediatric patients with congenital heart disease (CHD), the conventional GRASP and the proposed GRASP amplified by VS and KWIC (or GRASP + VS + KWIC) reconstruction for rtPC MRI were compared with respect to clinical standard PC MRI in measuring hemodynamic parameters (peak velocity, forward volume, backward volume, regurgitant fraction) at four locations (aortic valve, pulmonary valve, left and right pulmonary arteries). Results The proposed reconstruction method (GRASP + VS + KWIC) achieved better effective spatial resolution (i.e., image sharpness) compared with conventional GRASP, ultimately reducing the underestimation of peak velocity from 17.4% to 6.4%. The hemodynamic metrics (peak velocity, volumes) were not significantly ( p > 0.99) different between GRASP + VS + KWIC and clinical PC, whereas peak velocity was significantly ( p < 0.007) lower for conventional GRASP. RtPC with GRASP + VS + KWIC also showed the ability to assess beat‐to‐beat variation and detect the highest peak among peaks. Conclusion The synergistic combination of GRASP, VS, and KWIC achieves 25 ms effective temporal resolution (40 fps frame rate), while minimizing the underestimation of peak velocity compared with conventional GRASP

Individualized Language Plans

In the United States, individualized language plans (ILPs) have gained traction across K–12 schools. Much like the Individualized Education Programs (IEPs) used in special education, ILPs outline individualized goals, accommodations, and services for multilingual learners for their language development; however, unlike IEPs, ILPs are developed at the local level with no federal oversight or guidance. While scholars have recently called for the implementation of ILPs as a mechanism for promoting systemic change, there is a scarcity of scholarship that critically discusses or examines ILPs. In response to this gap, in this Teaching Issue article, we draw upon a combination of prior research, policy guidance, and our own review of ILP templates mandated or recommended in various states across the United States, to identify the characteristics, affordances, and constraints of ILPs. After discussing the promises and pitfalls of large‐scale implementation of these tools, we close this paper with two recommendations for teachers and policymakers who may consider adopting ILPs: to emphasize instructional support and a multiplicity of data and voices

Future transition from forests to shrublands and grasslands in the western United States is expected to reduce carbon storage

AbstractClimate change is expected to impact vegetation in the western United States, leading to shifts in dominant Plant Functional Types and carbon storage. Here, we used a biogeographic model integrated with a biogeochemical model to predict changes in dominant Plant Functional Type by 2070‚àí2100. Results show that under the Representative Concentration Pathway 4.5 scenario, 40% of the originally forested areas will transition to shrubland (7%) or grassland (32%), while under the Representative Concentration Pathway 8.5 scenario, 58% of forested areas shift to shrubland (18%) or grassland (40%). These shifts in Plant Functional Types result in a net overall loss in carbon storage equal to ‚àí60 gigagram of carbon and ‚àí82 gigagram of carbon under Representative Concentration Pathway 4.5 and 8.5, respectively. Our findings highlight the need for urgent action to mitigate the effects of climate change on vegetation and carbon storage in the region.</jats:p

Co‐rumination between friends

Despite its implications for adjustment, little is known about factors that support co‐rumination in friendships. The current multi‐method, longitudinal study addressed this question with 554 adolescents ( M age = 14.50; 52% girls; 62% White; 31% Black; 7% Asian American) from the Midwestern United States in 2007–2010. Adolescents were observed talking about problems with a friend and reported on their outcome expectations for problem disclosures, relationship provisions during problem talk, and problem perceptions after problem talk. Participants reported on outcome expectations again 9 months later. Results indicate that the positive relationship provisions associated with co‐rumination may outweigh negative problem perceptions in predicting adolescents\u27 outcome expectations for problem disclosures over time. Implications for the potentially reinforcing nature of co‐rumination are discussed

Distinct bacterial succession and functional response to alginate in the South, Equatorial, and North Pacific Ocean

The availability of alginate, an abundant macroalgal polysaccharide, induces compositional and functional responses among marine microbes, but these dynamics have not been characterized across the Pacific Ocean. We investigated alginate‐induced compositional and functional shifts (e.g., heterotrophic production, glucose turnover, hydrolytic enzyme activities) of microbial communities in the South Subtropical, Equatorial, and Polar Frontal North Pacific in mesocosms. We observed that shifts in response to alginate were site‐specific. In the South Subtropical Pacific, prokaryotic cell counts, glucose turnover, and peptidase activities changed the most with alginate addition, along with the enrichment of the widest range of particle‐associated taxa (161 amplicon sequence variants; ASVs) belonging to Alteromonadaceae , Rhodobacteraceae , Phormidiaceae , and Pseudoalteromonadaceae . Some of these taxa were detected at other sites but only enriched in the South Pacific. In the Equatorial Pacific, glucose turnover and heterotrophic prokaryotic production increased most rapidly; a single Alteromonas taxon dominated (60% of the community) but remained low (<2%) elsewhere. In the North Pacific, the particle‐associated community response to alginate was gradual, with a more limited range of alginate‐enriched taxa (82 ASVs). Thus, alginate‐related ecological and biogeochemical shifts depend on a combination of factors that include the ability to utilize alginate, environmental conditions, and microbial interactions

The DECam Ecliptic Exploration Project (DEEP). VI. First Multiyear Observations of Trans-Neptunian Objects

Abstract We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discoveries. Each individual detection for our objects resulted from a digital tracking search at TNO rates of motion, using two-to-four-hour exposure sets, and the detections were subsequently linked across multiple observing seasons. This procedure allows us to find objects with magnitudes m VR ≈ 26. The object discovery processing also included a comprehensive population of objects injected into the images, with a recovery and linking rate of at least 94%. The final orbits were obtained using a specialized orbit-fitting procedure that accounts for the positional errors derived from the digital tracking procedure. Our results include robust orbits and magnitudes for classical TNOs with absolute magnitudes H ∼ 10, as well as a dynamically detached object found at 76 au (semimajor axis a ≈ 77 au). We find a disagreement between our population of classical TNOs and the CFEPS-L7 three-component model for the Kuiper Belt.</jats:p

Partisan animosity through the lens of blame: Partisan animosity can be reduced by a historicist thinking intervention

Partisan animosity has been on the rise in America. Partisan animosity involves blame, wherein political partisans blame outparty members for their beliefs and actions. Here, we examine whether a historicist thinking intervention—drawn from research on blame mitigation—can reduce partisan animosity. The intervention consisted of three components: (1) a narrative about the idiosyncratic development of one political opponent paired with (2) a message about how unique life experiences shape everyone’s political beliefs and (3) a suggestion that outparty members can be changed by future formative experiences. Experiments 1 and 2 showed that the intervention reduced cold feelings—measured via Feeling Thermometer—towards the outparty for both Democrats and Republicans. Experiments 3 and 4 focused on more specific emotional changes. Experiment 3 showed that, for Democrats, the intervention increased compassion. Experiment 4 showed that, for Republicans, the intervention reduced disgust, disapproval, anger, and contempt, but had no impact on compassion. For Democrats, but not for Republicans, reductions in animosity were mediated by reduced perceptions of control of self-formation, the mediator identified in prior work on historicist thinking and blame mitigation.</jats:p

Psychometrics of rating scales for externalizing disorders in Japanese outpatients: The ADHD Rating Scale and the Disruptive Behavior Disorders Rating Scale

AbstractObjectivesThis study validated the Japanese version of the Attention‐Deficit/Hyperactivity Disorder‐Rating Scale‐5 (ADHD‐RS‐5) and the Disruptive Behavior Disorders Rating Scale. We extended the ADHD‐RS‐5 by adding the oppositional defiant disorder and conduct disorder subscales to compare the two rating scales psychometrically.MethodsWe examined the internal consistency, test‐retest reliability, construct validity and criterion validity of the two rating scales in 135 Japanese outpatients aged 6–18 years.ResultsThe internal consistency and test‐retest reliability were good for all the subscales of the two rating scales except for the conduct disorder subscale of the ADHD‐RS‐5 extended. Good construct validity was revealed by expected correlational patterns between subscales from the two rating scales and the Children Behavior Checklist. The criterion validity was good for all the subscales of the two rating scales rated by parents, while teacher‐ratings revealed substantially lower predictive ability for all the subscales. Agreement between parent‐ and teacher‐ratings of the two rating scales was generally moderate and using predictive ratings alone of both ratings showed the best predictive ability among the integration methods examined.ConclusionThe two rating scales have sound psychometric properties and will aid in screening and severity assessment of externalizing disorders in Japanese clinical settings.</jats:sec
