The role of data-driven methods in power system security assessment from aggregated grid data

Data-driven techniques have been considered as an enabling technology for reducing the computational burden of both static and dynamic power system security analysis. Anyway, the studies reported in the literature mainly focused on inferring from historical data the mapping between the bus variables before and after a certain contingencies set, while, to the best of the Author's knowledge, limited contributions have been devoted to try and classify the power system security state by processing aggregated grid data. This is a relevant issue to address for a Transmission System Operator since it could allow a sensible decrease in the computational burden and, considering that aggregated grid data can be reliably predicted from several hours to one day ahead, it may enable the evolution of security assessment to security forecasting. In trying and filling this research gap, this paper explores the role of machine learning and feature selection algorithms. A realistic case study involving 2 years of synthetic grid data simulated on the Italian power system model against future potential operational scenarios characterized by a high share of renewables is presented and discussed to identify the most promising computing paradigms, analyzing the criticality of tuning the feature selection and classifier algorithms.

Association of an interleukin abnormality with the T cell defect in Hodgkin's disease

Abstract The cellular immune defect in untreated Hodgkin's disease (HD) has long been recognized. This defect appears to be responsible for at least some of the morbidity and ultimately the mortality associated with the disease. In recent years, many studies have shown that the T cell component of the immune response is the apparent site where the defect in HD exists and where the immunoregulatory abnormalities that may account for the deficit are observed. The discovery of the lymphokines and monokines, comprising the human interleukin system, has elucidated some aspects of the regulatory control of the functional pathways involved in T lymphocyte activation and proliferation. The interleukin system can therefore provide the framework to dissect immunodeficiency states, such as that seen in HD. The present study indicates that HD patients' interleukin 1 (IL1) response appears to be normal, as is their T cell proliferative response to exogenous IL2. Interleukin 2 production by HD patients' peripheral blood mononuclear cells, however, is decreased when compared with age/sex-matched controls. The inability to generate IL2 after appropriate stimulation may reflect either a primary cellular defect or a regulatory defect, such as excessive immunosuppression, giving rise to the characteristic T cell hyporesponsiveness seen in HD.

Ganglioside antigen of DU‐PAN‐2 in a human pancreatic cancer

DU‐PAN‐2 reactive gangliosides were isolated from the tumor of a patient with pancreatic cancer (duct cell carcinoma, moderately differentiated adenocarcinoma), having a negative Lewis blood phenotype, and were analyzed by means of TLC‐immunostaining, enzyme‐linked immunosorbent assay (ELISA), permethylation study, 1 H NMR spectroscopy and fast atom bombardment mass spectrometry. The structures of the gangliosides were found to be NeuAcα2‐3Ga1β1‐3G1cNAcβ1‐3Ga1β1‐4Glcβ1‐1′Cer, containing normal and hydroxy fatty acids. By TLC‐immunostaining and ELISA with chemically synthesized gangliosides, DU‐PAN‐2 was demonstrated to react strongly with IV 3 αNeuAc‐Lc 4 Cer, weakly with IV 3 αNeuAc‐nLc 4 Cer, and moderately with IV 6 αNeuAc‐Lc 4 Cer and IV 6 αNeuAc‐nLc 4 Cer. Thus it was concluded that the DU‐PAN‐2 reactive ganglioside in the tumor is IV 3 αNeuAc‐Lc 4 Cer and that DU‐PAN‐2 has a rather broad specificity.

EXAMINING SIMULTANEOUS ALCOHOL AND ∆9-TETRAHYDROCANNABINOL SELF-ADMINISTRATION ON BEHAVIORAL FLEXIBILITY AND DORSAL STRIATAL CB1 EXPRESSION IN CHAP MICE

Although marijuana and alcohol are two of the most commonly used drugs in the United States, relatively little is understood about how these drugs interact to effect drug use, cognitive behaviors, and neurophysiological changes. Specific drug use patterns such as simultaneous use may produce differential effects for consumption and other behaviors in addition to unique neurobiological changes compared to singular drug use. In order to better understand the effects of simultaneous alcohol and marijuana (SAM) use, we used the selectively bred crossed High Alcohol Preferring mice to examine consummatory, cognitive, and neurobiological changes following chronic alcohol and THC self-administration. We hypothesized that SAM mice would consume more drug than animals exposed to either substance alone. We used an operant behavioral flexibility paradigm to assess cognitive impairments believing that drug-exposed animals would show deficits relative to Control animals, with SAM mice being the most impaired of all drug conditions. Finally, we assessed CB1 receptor changes in the dorsal striatum, as this region is critical for behavioral flexibility (Bissonette &amp; Powell, 2012; Ragozzino, 2007), CB1 receptors are the primary target of THC and these receptors are involved in numerous alcohol related behaviors (Maldonado et al., 2006; Pava &amp; Woodward, 2012). Contrary to our hypothesis, SAM animals did not consume higher levels of drug compared to mice exposed to only THC or alcohol. Interestingly, female THC consumption was robust when THC was consumed alone but was reduced when simultaneous access to alcohol was available. Surprisingly, although we speculated that drug-exposed mice would be impaired compared to Control animals, and that SAM animals would likely be more compromised than THC and alcohol for Reversal Learning and Attentional Set-Shifting respectively, behavioral flexibility deficits were absent in our paradigm. Finally, alterations to dorsal striatal CB1 receptor expression were observed following a Short Abstinence period. Despite an absence of cognitive behavioral effects, this research contributes to furthering our understanding of co-drug use for consummatory and neurobiological changes, both of which are critically necessary given the evolving landscape surrounding simultaneous alcohol and recreational marijuana use.

Chronic diabetic ulcers under the first metatarsal head treated by staged tendon balancing: a prospective cohort study

We studied a cohort of 26 diabetic patients with chronic ulceration under the first metatarsal head treated by a modified Jones extensor hallucis longus and a flexor hallucis longus transfer. If the first metatarsal was still plantar flexed following these two transfers, a peroneus longus to the peroneus brevis tendon transfer was also performed. Finally, if ankle dorsiflexion was &amp;lt; 5 degrees with the knee extended, a Strayer-type gastrocnemius recession was performed. The mean duration of chronic ulceration despite a minimum of six months' conservative care was 16.2 months (6 to 31). A total of 23 of the 26 patients were available for follow-up at a mean of 39.6 months (12 to 61) after surgery. All except one achieved complete ulcer healing at a mean of 4.4 weeks (2 to 8) after surgery, and there was no recurrence of ulceration under the first metatarsal. We believe that tendon balancing using modified Jones extensor hallucis longus and flexor hallucis longus transfers, associated in selected cases with a peroneus longus to brevis transfer and/or Strayer procedure, can promote rapid and sustained healing of chronic diabetic ulcers under the first metatarsal head.

Pretrained Language Encoders are Natural Tagging Frameworks for Aspect Sentiment Triplet Extraction

Aspect Sentiment Triplet Extraction (ASTE) aims to extract the spans of aspect, opinion, and their sentiment relations as sentiment triplets. Existing works usually formulate the span detection as a 1D token tagging problem, and model the sentiment recognition with a 2D tagging matrix of token pairs. Moreover, by leveraging the token representation of Pretrained Language Encoders (PLEs) like BERT, they can achieve better performance. However, they simply leverage PLEs as feature extractors to build their modules but never have a deep look at what specific knowledge does PLEs contain. In this paper, we argue that instead of further designing modules to capture the inductive bias of ASTE, PLEs themselves contain "enough" features for 1D and 2D tagging: (1) The token representation contains the contextualized meaning of token itself, so this level feature carries necessary information for 1D tagging. (2) The attention matrix of different PLE layers can further capture multi-level linguistic knowledge existing in token pairs, which benefits 2D tagging. (3) Furthermore, with simple transformations, these two features can also be easily converted to the 2D tagging matrix and 1D tagging sequence, respectively. That will further boost the tagging results. By doing so, PLEs can be natural tagging frameworks and achieve a new state of the art, which is verified by extensive experiments and deep analyses.

The Roots Factor

Martin Luther King, Jr.s upbringing in the Ebenezer Baptist Church in Atlanta, Georgia, in the 1930s and ’40s is treated, with some focus on how “the Ebenezer tradition” and the larger African American church culture in Atlanta and the South impacted his growing understanding of and vision for the Christian church as a whole, from his childhood to his adult years. As the son and grandson of Ebenezer pastors and of pious women who were an active presence in that congregation for generations, King is pictured as one who always attached great significance to the church and church-related concerns. His early sense of the church as “a second home,” as extended family, as the fountainhead of culture, as a refuge, as educational center, as custodian of a deep and vital spirituality, and as a benchmark for congregational activism is underscored. The chapter concludes with attention to King’s struggle to negotiate the boundaries between the Christian fundamentalism to which he was exposed at Ebenezer and the theological liberalism he studied as a student at Morehouse College, Crozer Theological Seminary, and Boston University.

Incentivized Federated Learning and Unlearning

To protect users' right to be forgotten in federated learning, federated unlearning aims at eliminating the impact of leaving users' data on the global learned model. The current research in federated unlearning mainly concentrated on developing effective and efficient unlearning techniques. However, the issue of incentivizing valuable users to remain engaged and preventing their data from being unlearned is still under-explored, yet important to the unlearned model performance. This paper focuses on the incentive issue and develops an incentive mechanism for federated learning and unlearning. We first characterize the leaving users' impact on the global model accuracy and the required communication rounds for unlearning. Building on these results, we propose a four-stage game to capture the interaction and information updates during the learning and unlearning process. A key contribution is to summarize users' multi-dimensional private information into one-dimensional metrics to guide the incentive design. We further investigate whether allowing federated unlearning is beneficial to the server and users, compared to a scenario without unlearning. Interestingly, users usually have a larger total payoff in the scenario with higher costs, due to the server's excess incentives under information asymmetry. The numerical results demonstrate the necessity of unlearning incentives for retaining valuable leaving users, and also show that our proposed mechanisms decrease the server's cost by up to 53.91\% compared to state-of-the-art benchmarks.

Economic impacts of petroleum industry in states of Pahang and Terengganu

Petroleum industry in Malaysia has created significant contribution to the Malaysian economy as a whole. However, the growth and development of the industry does not necessarily to bring considerable economic linkages to the local and neighboring economies where the industry is located, and thus fail to contribute to the economic diversification of local economies. This paper validates this expectation by examining the economic impacts of petroleum industry in the states of Terengganu and Pahang. Regional input-output model that developed by using location quotient, has been used as the main methodology in this paper. Results are consistent with our expectation that the state of Terengganu does not benefit largely from the petroleum industry but contributes more to the economic diversification for the state of Pahang. One of the explanations to this finding is that petroleum related activities such as petroleum refinery and support services are outsourced to the state of Pahang.

Evaluation of a community-based integrated heroin addiction treatment model in Chinese patients

In this study, we analyzed the efficacy and feasibility of a community-based integrated heroin addiction treatment model in Chinese patients. The 210 heroin addicts belonging to six Chinese communities received an integrated biopsychosocial intervention that included pharmacological treatment, counseling and social assistance. High proportions of study participants were retained at the 12-month (91.9%; 193/210) and 24-month (88.1%; 185/210) follow-up visits. The number of morphine-positive subjects declined from 61.4% at baseline to 36.2% and 30.5% (<i>Q</i>=52.01; <i>P</i><0.001) after 12 and 24 months, respectively. The crime rate decreased from 32.4% at baseline to 2.2% and 1.6% (<i>Q</i>=7.84; <i>P</i><0.001) after 12 and 24 months, respectively. The number of patients that were employed increased from 24.3% at baseline to 37.8% and 50.8% after 12 and 24 months, respectively (<i>Q</i>=41.68; <i>P</i><0.001). Addiction-related issues and mental health status improved according to Addiction Severity Index (ASI) and Symptom Checklist-90 (SCL-90). We therefore conclude that this community-based, integrated heroin addiction treatment model is highly feasible with high treatment retention, reduced drug use, a lower crime rate, improved health and increased employment.
