Faculty Research 2026
We present a collection of 17 high-quality long-read inbred mouse strain genomes with complete annotation (contig N50s of 0.8-33.9 Mbp). This collection includes 12 widely used classical laboratory strains and 5 wild-derived strains. We have resolved previously incomplete genomic regions, including the major histocompatibility complex (MHC), defensin cluster, T cell receptor, and Ly49 complexes. Hundreds of non-reference genes from previous publications not found in GRCm39, such as Defa1, Raet1a, and Klra20 (Ly49T), were localized in the new reference genomes. We conducted a genome-wide scan of variable number tandem repeats (VNTRs) within the coding regions, identifying over 400 genes with VNTR …
Human Capital And Labor Market Effects Of Elite Schooling In England, Scotland, And Wales: New Causal Evidence From Nonparametric Bounds, Zhanhan Yu, Vikesh Amin, Carlos A. Flores, Alfonso Flores-Lagunes, Giuseppe Germinario
Human Capital And Labor Market Effects Of Elite Schooling In England, Scotland, And Wales: New Causal Evidence From Nonparametric Bounds, Zhanhan Yu, Vikesh Amin, Carlos A. Flores, Alfonso Flores-Lagunes, Giuseppe Germinario
Upjohn Institute Working Papers
We estimate the causal effect of attending elite schools in England, Scotland, and Wales on human capital and labor market outcomes for cohorts of children from the 1958 National Child Development Study and the 1970 British Cohort Study. For identification, we employ a nonparametric partial-identification approach that provides bounds on the causal effect by assuming that, on average, there is positive selection into elite school attendance, and that attending an elite school does not worsen average potential human capital or labor market outcomes. The bounds indicate that there could possibly be large education and labor market returns from attending an …

Mycobacteria Infection Induced Cascade Of Epigenetic Alterations Promote Training In Bystander Macrophages, Shah E. Jahan Gulzar Mr
Mycobacteria Infection Induced Cascade Of Epigenetic Alterations Promote Training In Bystander Macrophages, Shah E. Jahan Gulzar Mr
Theses and Dissertations
Mycobacterium tuberculosis (Mtb) remodels host cell functions to support its intracellular persistence. While the effects of Mtb infection on infected macrophages are well characterized, responses of uninfected bystander cells in the same microenvironment remain poorly understood. Here, we show that Mtb infection triggers widespread epigenetic reprogramming not only in infected macrophages but also in neighbouring bystander cells. These bystander macrophages acquire active chromatin marks, exhibit distinct transcriptional changes, and display enhanced immune responsiveness, thereby increasing resistance to both homologous and heterologous infections. We identify interleukin-1 beta secreted by infected cells as a key mediator of this process. Functionally, trained bystander …

Implementing Mandatory Minimum Nurse-To-Patient-Ratios In British Columbia, Canada, Mycal Barrowclough, Tarya Morel
Creating Healthy Work Environments (CHWE)
Researchers and nursing advocates have been advocating for safe staffing for many years; unions and health employers have implemented many different approaches with little success. The nursing shortage was already reaching a critical level when the COVID-19 pandemic dramatically highlighted and worsened the impacts of understaffing, leaving nurses consistently working short in an overstretched system. Shift after shift, nurses find themselves risking their licenses and their own mental and physical health as they do their best to meet their patients’ care needs.
In light of the rapidly worsening nursing shortage, it became clear that a different approach was needed. We …

Use Of Integrative Self-Care To Promote Resilience And Mental Health In Nursing Students, Stacey C. Nseir, Betty Parisek, Stephanie Kelly
Creating Healthy Work Environments (CHWE)
Background: Students enrolled in nursing programs have clinical, academic, and personal challenges which can lead to depression, anxiety, and burnout (Vargas-Benitez et al., 2023). Challenges are likewise present in nurses who practice in a variety of settings and nurses have higher levels of depression, anxiety, and burnout compared to the general population (Guttormson et al., 2022). Studies have shown that the practice of self-care decreases depressive and anxiety symptomatology (Pilkington et al., 2020) and burnout (Horn, 2020) and increases resilience (Blackburn et al., 2020).
Methods: This study is a three-year prospective repeated measures cohort trial for pre-licensure nursing students entering …
Hands Off Mahmoud Khalil: Why The State Department Can't Lawfully Revoke Green Cards, Enforce Immigration Law, Or End Status, Nicolas Garon
Hands Off Mahmoud Khalil: Why The State Department Can't Lawfully Revoke Green Cards, Enforce Immigration Law, Or End Status, Nicolas Garon
Et Cetera
In recent months, the Trump Administration has revived a controversial legal strategy aimed at stretching immigration law to enable aggressive enforcement. Among these efforts is a troubling misconception, exemplified by the case of Mahmoud Khalil, that the U.S. Department of State holds authority to revoke the legal status of individuals inside the country, deport them, or cancel lawful permanent resident (LPR) status. This claim directly contradicts longstanding immigration law, which limits the State Department’s role to visa issuance abroad and grants no domestic enforcement authority. Even visa revocations do not terminate lawful status once an individual is admitted. Despite this …
Decentralized, But Not Above The Law: Analyzing Dao Governance And Regulation, Nathan Cline
Decentralized, But Not Above The Law: Analyzing Dao Governance And Regulation, Nathan Cline
Et Cetera
Decentralized autonomous organizations (DAOs) are transforming how people collaborate and manage collective ventures, yet the law has lagged behind this innovative form of organization. Because DAOs rely on smart contracts rather than conventional organizational infrastructure, it is often unclear how they fit into existing laws. This paper defines DAOs, outlines the current regulatory frameworks governing them, and demonstrates where those frameworks fall short. It argues that DAOs should be recognized as a distinct form of corporate entity and that a tailored exemption from federal securities laws is necessary for them to operate effectively. The proposed model offers a practical path …

Resilient Grid Architectures For High Renewable Penetration: Electrical Engineering Strategies For 2030 And Beyond, Ehab Bayoumi
Resilient Grid Architectures For High Renewable Penetration: Electrical Engineering Strategies For 2030 And Beyond, Ehab Bayoumi
Mechanical Engineering
The global shift toward decarbonized power systems is driving unprecedented penetration of variable renewable energy sources, especially wind and solar PV. Legacy grid architectures, built around centralized, dispatchable synchronous generation, are ill-suited to manage the bidirectional power flows, reduced inertia, and new stability constraints introduced by inverter-based resources. Existing research offers deep but fragmented insights into individual elements of this transition, such as advanced power electronics, microgrids, or market design, but rarely integrates them into a coherent architectural vision for resilient, high-renewable grids. This review closes that gap by synthesizing technical, architectural, and institutional perspectives into a unified framework for …

Adaptive Phase-Locked Loop Strategy Based On Improved Second-Order Linear Active Disturbance Rejection Control, Hui Li, Jiaqi Zhao, Xinqiao Fan
Journal of Electric Power Science and Technology
To address the problems of traditional phase-locked loops (PLLs), including slow dynamic response, poor detection accuracy, and insufficient suppression capability under complex operating conditions such as grid voltage unbalance and sudden frequency changes in flexible DC transmission systems, an adaptive PLL control strategy based on improved second-order linear active disturbance rejection control (LADRC) is proposed. This strategy employs a cross-decoupled dual complex coefficient filter with a frequency feedback loop as a pre-filtering stage to extract and separate the positive- and negative-sequence components of the voltage. In addition, a first-order feedforward derivative stage is introduced at the input reference signal of …

Bi-Level Low-Carbon Optimization Operation Method For Electric Vehicle Grid Integration Considering Peak Load, Jinjin Zhao, Junjie Zhong, Jie Dai, Ziling Huang
Journal of Electric Power Science and Technology
As an emerging green energy carrier, electric vehicles (EVs), with their long idle time and energy storage characteristics, can not only relieve load pressure of the electric power grid but also achieve coordinated interaction between power sources and loads through rational scheduling, thereby reducing carbon emissions. Therefore, how to fully leverage the flexibility of EVs and develop an optimization operation strategy that takes the objectives of electric power grid safety, economy, and low carbon into account has become an urgent and critical issue. A low-carbon optimization scheduling method for peak loads is proposed, focusing on the scheduling strategy of EVs …

Static Voltage Stability Assessment Of Power Systems Based On Mwmote And Ssa-Kelm, Songkai Liu, Jun Cao, Pan Su, Kun Gao, Yuheng Wu, Ming Wan, Di Ai
Journal of Electric Power Science and Technology
The static voltage stability assessment method of a power system based on data drive usually has the problem of an unbalanced sample category in the initial data, which makes the performance of the data-driven assessment model greatly affected. Therefore, a static voltage stability assessment method of a power system is proposed based on the majority weighted minority oversampling technique (MWMOTE) and sparrow search algorithm-kernel extreme learning machine (SSA-KELM ) . First, MWMOTE is used to solve the problem of an unbalanced sample category and increase sample diversity. Then, the KELM model parameters are optimized by using SSA, and the static …
Aggregation Optimization Method For Offshore Wind-Thermal-Storage Systems Based On Membership Degree Analysis, Da Xie, Zhou Tian, Yu Zhang, Yuchuan Wang
Aggregation Optimization Method For Offshore Wind-Thermal-Storage Systems Based On Membership Degree Analysis, Da Xie, Zhou Tian, Yu Zhang, Yuchuan Wang
Journal of Electric Power Science and Technology
To address the collaborative optimization of offshore wind-thermal-storage systems, this paper proposes an aggregation optimization method based on membership degree analysis. The proposed method enables dynamic resource aggregation and flexible scheduling by modeling and optimizing offshore wind farms, thermal power plants, and energy storage systems. Specifically, the aggregation set is generated using the Cartesian product, and initial aggregation schemes are filtered by introducing constraint conditions. A comprehensive evaluation is then conducted using membership degree analysis across three dimensions: wind power accommodation rate, economic benefit, and coordinated frequency regulation capability of thermal power. Simulation results demonstrate that the optimized aggregation configuration …

Prediction Of Transmission Line Icing In Micrometeorological Areas Based On Rf-Gswoa-Svrm, Wei Zhang, Xingjie Liu, Rui Huang, Yizhou Rao, Jianning Liu, Dan Chen
Journal of Electric Power Science and Technology
The transmission lines in the micrometeorological area are more prone to icing, so it is extremely destructive to the safe operation of the power grid system. In view of the characteristics that icing monitoring data in micrometeorological areas is scarce, and interference is strong, RF-GSWOA-SVRM, a prediction method for transmission line icing in micrometeorological areas based on random forest (RF), global search whale optimization algorithm (GSWOA), and support vector regression machine (SVRM), is proposed to improve the accuracy of icing prediction. Firstly, the RF algorithm is used to extract the correlation between transmission line icing and micrometeorological data, thereby reducing …

Journal of Electric Power Science and Technology
The large-scale integration of renewable energy sources poses significant challenges to provincial distribution network disaster recovery systems, particularly in data processing and resource optimization. Therefore, an intelligent and dynamically optimized resource management method is urgently required to enhance resource utilization efficiency, reduce operational costs, and improve system stability. This paper proposes a dynamic resource optimization method for provincial distribution network disaster recovery systems by integrating an adaptive feedback mechanism with the grey wolf optimization (GWO) algorithm. At the data acquisition layer, a multi-level adaptive feedback mechanism is introduced to realize real-time feedback control. At the resource allocation and system operation …

Hybrid Configuration Method For Grid-Forming And Grid-Following Energy Storage Systems Considering Transient Stability And Dynamic Support, Baoyu Zhai, Shuchao Liang, Zh I Xu, Huan Jiang, Haiyang Wu
Journal of Electric Power Science and Technology
With the significant increase in the proportion of renewable energy, power systems exhibit characteristics of low inertia and weak damping, posing challenges to transient stability. Traditional grid-following energy storage systems (GFL-ESS) lack the capability to autonomously support the operation of power systems, necessitating the configuration of grid-forming energy storage systems (GFM-ESS) to provide voltage support and enhance system stability. To address these issues, this paper investigates the proportion of GFM-ESS units required to effectively improve the transient stability and dynamic support capabilities of the system. First, a transient model of the hybrid grid-following (GFL) and grid-forming (GFM) system is developed …

Transmission Line Protec Tion Method Based On Time-Frequency Analysis Matr Ix And Bp Neural Network, Jifeng Fan, Yongqiang Wang, Tianlong Zhang, Peng Chen, Yunfeng Yan
Journal of Electric Power Science and Technology
To address the misoperation and failure issues of existing transient protection schemes for high-voltage transmission lines, this paper proposes a transmission line protection method that combines a back propagation (BP) neural network with the time-frequency matrix of transient voltage signals. Transient protection of transmission lines is implemented based on the time-frequency analysis matrix obtained through a one-dimensional continuous wavelet transform of fault-induced voltage traveling waves. According to the existing fault voltage traveling wave data or simulated fault voltage traveling wave data, the time-frequency matrix is obtained by time-frequency analysis. The part with obvious time-frequency characteristics is taken as the input …

Multiformer-Tsa-Based Photovoltaic Power Forecasting Method, Ziwen Cai, Zhukui Tan, Yun Zhao, Yuelang Zhang, Xipeng Liu, Houyi Zhang
Journal of Electric Power Science and Technology
To address the limitations of current photo voltaic power forecasting methods, which rely heavily on meteorological monitoring and classification techniques and are unable to achieve accurate all-weather forecasting under large-scale complex data, a Multiformer-TSA method based on a two-stage attention (TSA) mechanism is proposed for photovoltaic power forecasting. First, a cross-scale embedding layer is constructed to generate staged sampling tokens and collect photovoltaic sequences at different scales, thus extracting cross-scale features. Then, point-based segments of different dimensions in multivariate time series are embedded to form new feature vectors, capturing cross-dimensional dependencies. Finally, cross-scale and cross-dimensional dependency information is fused through …
Frequency Regulation Method Of Wind-Storage Coordination Considering Differences In Wind Turbine State, Xilin Zhao, Xiaoyu Ye, Jinxing Li
Frequency Regulation Method Of Wind-Storage Coordination Considering Differences In Wind Turbine State, Xilin Zhao, Xiaoyu Ye, Jinxing Li
Journal of Electric Power Science and Technology
To address the issue of frequency stability in power systems under large-scale wind power grid integration, a frequency regulation control method of wind-storage coordination considering the differences in wind turbine states is proposed. Initially, a power system model incorporating wind power is constructed, with model predictive control (MPC) as the primary controller to optimize the output of the wind turbines. Then, on this basis, considering the differences in wind turbine state, the state consistency control (SCC) method is introduced to address the problem of online computational complexity arising from uniform control of all wind turbines via MPC, thereby reducing the …

Stability Analysis Of Fractional-Frequency Offshore Wind Power System Based On Lyapunov Energy Function, Yumeng Jiang, Peiyang He, Ruanming Huang, Wei Xie, Chen Qian, Boyang Zhao, Yongqing Meng
Journal of Electric Power Science and Technology
The fractional-frequency transmission method has become an important solution for large-scale long-distance offshore wind power collection and transmission due to its advantages in transmission losses and construction costs compared with power frequency and direct current transmission methods. However, the stability research of fractional-frequency offshore wind power systems, especially the analysis under the background of typical large disturbances in system operation, is lacking. A high-order nonlinear state space model of the fractional-frequency offshore wind power system is proposed, and the sector-based nonlinear method is used to deal with the high-order nonlinear part of the model; the Lyapunov energy function of the …

Phase Selection Capacity Recovery Strategy For Full-Scale New Energy Grid Based On Coordinated Control And Protection, Lin Zhang, Hongbin Wang, Xun Chen, Xiangning Lin, Zhengtian Li, Fanrong Wei
Journal of Electric Power Science and Technology
The negative-sequence suppression control strategy and low-voltage ride-through control strategy are adopted when the inverter-based power supply fails, which leads to a serious inequality between the distribution coefficients of positive- and negative-sequence currents at the energy storage station side in a full-scale new energy system, resulting in incorrect phase selection of the phase current difference mutation element. Based on the fault sequence component network, the constraint condition for the correct phase selection of the phase current difference mutation element is derived. A phase selection performance recovery scheme based on fault component regulation is proposed, which can eliminate the degradation of …

State Estimation Of Supercapacitor Based On Transient Model, Shuang Rong, Xiaog Uang Chen, Wanlin Guan, Wenbo Hao, Yuanting Hu, Yanlong Liu, Jiandong Duan, Yuhan Wang
Journal of Electric Power Science and Technology
The multi-branch model of a supercap acitor can accurately describe the charge and discharge characteristics of a supercapacitor, but it is difficult to obtain the exact parameters when it is used to estimate the state of the supercapacitor, resulting in large errors in the state estimation results. In order to improve the accuracy of supercapacitor parameter identification and state estimation in the transient process, a state estimation algorithm combining an extended Kalman filter (EKF) and an adaptive unscented Kalman filter (AUKF) based on a transient model is proposed. Firstly, the model simplification feasibility in the case of fast charge and …

Optimal Load Distribution Method For Substations Based On Inter-Line Correlations, Ziqi Liu, Yin Zhai, Kuilin Fu, Shuran Liu, Wei Li, Xinyu Qie, Shiguang Zhan, Lili Chen
Journal of Electric Power Science and Technology
As the construction of new power systems advances, the spatio-temporal mismatch between the output of intermittent renewable energy and diversified load exacerbates the peak-valley difference in power grids, leading to an increased load rate of main transformers and a decline in load balance of each transformer within substations. This operational trend accelerates the risk of equipment aging and poses potential threats to the safe and stable operation of the power grid through hierarchical coupling effects. To address this issue, based on the hierarchical partition operation characteristics of substations and the spatio-temporal coupling relationship of outgoing line loads, a multidimensional evaluation …

Optimized Operation Of Integrated Energy System With Underwater Compressed Air Energy Storage Based On Power And Heat Storage, Shuai Shi, Xiaomeng Lu, Yuanyuan Li, Chunyang Gong, Wei Song, Xiaoliang Wang
Journal of Electric Power Science and Technology
At present, underwater compressed air energy storage (UW-CAES) is mainly used in isolated island power grids of islands or ports. Firstly, inland abandoned mine pit lakes are utilized to establish large-scale UW-CAES gas storage chambers, and an integrated energy system on land with UW-CAES is constructed. Secondly, a new heat supply mode is proposed, which realizes the power and heat storage integration of the energy storage system through the coordination of heat supply between the heat storage tank and the heat pump. Finally, the effects of operating cost, system benefit, wind power consumption, and low-carbon emissions of the integrated energy …
