Abstract
In this paper, multi-layer current data continuously observed in November 2021 was studied by statistical analysis, spectral analysis, and harmonic analysis in the shallow water area of the northern outer shelf of the East China Sea. The results showed that: during observation, the average velocity was 30.5cm/s, and the maximum velocity was 78.1cm/s. The velocity from 30cm/s to 40cm/s accounts for the largest proportion, and the maximum direction frequency was eastward, up to 12.4%. The stationary flow direction is northward and changes from northeast to northwest with the increase of depth. The current is a regular semi-diurnal current, and the current ellipse rotates clockwise. The major axis of the M2 tidal current ellipse ranges from 12.9cm/s to 37.7cm/s, and firstly increases, then keeps constant, and finally decreases with the increase of depth. This study fills in the blank of the autumn hydrodynamic data and can provide a reference for studying hydrodynamics in the Kuroshio affected area.

Authors: Yao Siyu , Wang Dongying , Yu Yang , Zhang Zhenrong 
Published: June 2023

Abstract
In order to meet the demand for large-scale magnetic field testing, this paper proposes a D-shaped magneto-refractive photonic crystal fiber (MRPCF) based on surface plasmon resonance (SPR) by using the erbium-doped material. By varying the diameter, location, and number of layers of the air holes, the four different Models A, B, C, and D structures are created, and the corresponding magnetic field sensing properties are analyzed. The simulation findings demonstrate that the magnetic field sensitivities of Models A, B, C, and D are 28 pm/mT, 48 pm/mT, 36 pm/mT, and 21 pm/mT, respectively when the magnetic field strength is 5 - 405 mT. Meanwhile, the figure of merit (FOM) of the four MRPCF-SPR sensors is investigated, which have FOMs of 4.8×10-4 mT-1, 6.4×10-4 mT-1, 1.9×10-4 mT-1, 0.9×10-4 mT-1. Model B has high sensitivity and large FOM. It shows that altering the structural design of the fiber can significantly improve the magneto-refractive effect of MRPCF. The proposed MRPCF has numerous uses in the areas of geological research, earthquake and tsunami monitoring, and military navigation. It can also be expected to enable quasi-distributed magnetic field sensing.
Source Range Estimation with Horizontal Arrays Using Frequency Difference Matched Field Processing in Shallow Water
Authors: Song Penghua , Wang Haozhong 
Published: June 2023

Abstract
Due to the modal interference, the ambiguity function of conventional matched field processing (CMFP) exists periodic solutions. To solve this problem, a frequency difference matched field processing (FDMFP) method with horizontal linear array (HLA) for estimating the source range is proposed. The method calculates the ambiguity function of two-neighbor-frequency between the measurement and the replica of each hydrophone, and then computes the high-order cross-spectrum. The range corresponding to the maximum of the ambiguity function is the optimal estimation. Because of the larger modal interference distances, the FDMFP can efficiently provide one-only optimal range instead of some of CMFP.

Authors: Chen Jiandong , Tian He 
Published: June 2023

Abstract
In order to realize the near real-time prediction of the ocean acoustic field, this paper conducted a comparative study of HYCOM data and NMDC data for the application of hydrographic datasets, and drew pseudo-color maps of ocean surface temperature distribution and sound velocity distribution characteristics in the area of 4°N~26°N and 105°E~1236°E respectively. Moreover, the 3D visual distribution of sound velocity in the ocean acoustic field in a 1° grid region of 114°E~115°E, 18°N~19°N is also conducted. Comparisons of the results with the two datasets shown that the acoustic velocity distribution characteristics generated by these two datasets remain consistent overall, and the data generated by HYCOM has more detailed features than the NMDC, however, NMDC data has smaller size and advantageous data type of acoustic velocity, which reduces the requirements for computer hardware and offers a faster processing speed.

Authors: Sun Shouyang , He Chuanlin , Yu Yang , Liu Zeqi 
Published: June 2023

Abstract
Active sonar is used for target detection in the bistatic detection system. When the target approaches or crosses the source-receiver line, the direct blast will cause serious interference in the received signal. The adaptive filtering algorithm is used to suppress the interference such as direct blast, and it is implemented on FPGA by System Generator. The results show that the adaptive filter can effectively suppress the direct blast, and the forward scattering signal submerged in direct blast can be displayed, and underwater target can be detected.
Research on the Estimation Method of Target Motion Parameters Based on Ternary Array
Authors: Zhang Yujie , Cui Hongxu , Wang Liang 
Published: June 2023

Abstract
The ternary array passive positioning technique performs the estimation of target distance and bearing by measuring the time delay difference between array elements. The estimates are limited by the geometric model and time delay measurement errors, and the positioning accuracy and reliability are poor. In this paper, we propose an orientation matching-based motion target localization model. By introducing the target motion model, and establish a matching objective function for the time delay difference obtained by calculating the predefined target motion trajectory and the actual received data of the ternary array separately. The matching objective function is optimally solved by using Burg algorithm in the AR spectrum estimation method, and a highly accurate and reliable target parameter estimation can be obtained in a short time. The results of computer simulation experiments verify the effectiveness of the method.

Authors: Wu Y H , Huang Y W 
Published: June 2023

Abstract
As one of the boundaries of ocean waveguide, the acoustic properties of seafloor sediments have been a hot research problem in ocean acoustic propagation and acoustic field modeling. The existing research has shown that the sound velocity in seafloor sediment is frequency dependent. In order to solve the problem that the sedimentary sound speed dispersing often be ignored in actual applications, this article uses the parabolic Newton to iterate to solve the dispersion equation to obtain the characteristic value of the normal mode. And the impact of frequency dispersion of sediment sound speed through simulation are studied. The results show that the sound wave in the time domain will appear more obvious broadening phenomenon, and the propagation loss will be reduced after considering the sound velocity dispersion of the sediment. Also, with the increase of frequency, the more obvious the effect of sound velocity dispersion on the sound propagation in the frequency range of sound velocity dispersion.
Greening rate in North Korea doubles South Korea

Published: June 2023

Abstract
South and North Korea have experienced contrasting economic developments since the 1950s while sharing similar climates. Previous studies revealed an overall long-term greening trend across the Korean Peninsula based on greenness data from coarse-resolution satellite images. However, there has been no comprehensive comparison of the greenness patterns and the driving mechanisms between two countries due to the limitations of coarse-resolution satellite data. Here, we performed cross-calibration among Landsat sensors and adopted a phenology-based approach to generate Landsat annual maximum Normalized Difference Vegetation Index (NDVImax) time series for each pixel from 1986 to 2017. We found that over 1986–2017, the greening rate in North Korea was almost twice that of South Korea. Cropland in South Korea is the main source of the greening discrepancy. The expansion of agricultural facilities in the stable cropland area and urbanization in the cropland loss area of South Korea contributed 57% to the significant negative NDVImax trend, which was dominant over the forest NDVImax increase resulting from rising temperatures, CO2 fertilization effects and afforestation projects. However, in North Korea, CO2 fertilization effects in the stable cropland area and transition from grassland to cropland promoted an increase in NDVImax, despite decreasing NDVImax in forest areas due to deforestation. Our results highlight the need for delineating fine-scale land-use changes to advance our understanding of regional vegetation dynamics.
Health Professional- and Volunteer-partnered Self-management Support (COMBO-KEY) to Promote Self-efficacy and Self-management Behaviors in People with Stroke: A Randomized Controlled Trial
Authors: Lo Suzanne H S , Chau Janita P C , Choi Kai C , Wong Rebecca Y M , Kwan Jackie C Y , Iu Issac H L 
Published: June 2023

Abstract

Background
Multiple systematic reviews have reported that self-management interventions are associated with positive impacts on self-efficacy and health-related quality of life (HRQoL) of people with stroke.

Purpose
This article reports the effects of an enhanced stroke self-management program.

Methods
Eligible adults with stroke were recruited from community-based organizations and a support group for a two-arm, assessor-blinded randomized controlled trial. Participants in the control group received usual care, while those in the intervention group also received the 8-week self-management program, Coaching Ongoing Momentum Building On stroKe rEcovery journeY (COMBO-KEY), consisting of four individual home visits and five follow-up phone calls, delivered by healthcare professionals and trained volunteers. Assessments were conducted at baseline and after the intervention, for outcomes of self-efficacy, satisfaction with the performance of self-management behaviors, HRQoL, and community reintegration, which were analyzed using generalized estimating equations (GEEs).

Results
134 Participants were recruited [mean age = 64.1 years, standard deviation (SD) = 12.7]. Over 80% of the participants had a first-ever stroke [mean years after first stroke: 4.2 (SD = 5.1)]. The GEE analysis revealed that the intervention group participants showed significantly greater improvements in self-efficacy, satisfaction with their performance of self-management behaviors, HRQoL, and community reintegration at 8-week follow-up with respect to their baseline levels.

Conclusions
The COMBO-KEY program showed effective improvements in recovery outcomes of people with stroke. Future research should explore the inclusion of virtual/hybrid sessions, strategies to assess health conditions of people with stroke via online modes, and assessment of goal attainment and actual performance of self-management behaviors.
The Weakness of Relationality as a Unifying Concept in Tort
Authors: Borgerson Timothy 
Published: June 2023

Abstract
Corrective justice and civil recourse theorists aim to provide coherent and unified theories of tort law—and private law more generally. In doing so, they have identified relationality as a key unifying concept. For corrective justice theorists, relational rights and wrongs are based on the internal moral structure of private law—namely a notion of rights that protect a person’s capacity to exercise purposive agency. For civil recourse theorists, on the other hand, relational rights and wrongs are grounded in the positive law. This essay assesses whether relationality does, in fact, provide a strong foundation for grounding a theory of tort law. It argues that, while relationality certainly describes aspects of the remedial relationship between right and wrong, it does not generally provide sufficient guidance for understanding what kinds of “relational wrongs” should be redressable by tort in the first instance.
Risky drinking and other drug use in adults with chronic conditions in the United States: differential associations by race/ethnicity
Authors: Cook Won Kim , Kerr William C , Tam Christina C , Li Libo 
Published: June 2023

Abstract
Co-use of multiple drugs may prolong or increase heavy drinking, even for individuals with health conditions adversely affected by it. Patterns of alcohol and drug use may vary across racial/ethnic groups, with differential implications for health. This study examines racial/ethnic differences in the associations between risky drinking and other drug use in adults with diabetes, hypertension, heart disease, or cancer. Multiple logistic regression modeling, stratified by condition, was performed using a nationally representative sample of adults drawn from the 2015 to 2019 National Survey on Drug and Health. The outcome was risky drinking (consuming more than 7/14 drinks weekly). Other drugs considered were tobacco, marijuana, illicit drugs, and non-medical prescription drugs. Covariates included age, sex, education, income, marital/cohabitation status, health insurance coverage, and self-rated health status. Each drug category was positively associated with risky drinking across all four conditions. Racial/ethnic minority adults were less likely than White adults to engage in risky drinking, with this pattern most consistent for those with hypertension. Other drug use in minority adults (i.e. tobacco and illicit drug use in Black and Hispanic adults, and marijuana and prescription drug use in Asian adults) was associated with disproportionately greater odds of risky drinking compared with White adults. This pattern was more prominent for those with a heart condition, and not found for those with cancer. Future interventions might address co-use of alcohol and other drugs in adults with chronic conditions, with special attention to racial/ethnic minority adults.

Published: June 2023

Abstract

Background
It is unclear whether pathological staging is significant prognostically and can inform the delivery of adjuvant therapy after pancreatectomy preceded by neoadjuvant therapy.

Methods
This multicentre retrospective study included patients who underwent pancreatectomy for pancreatic ductal adenocarcinoma after neoadjuvant treatment at two Italian centres between 2013 and 2017. T and N status were assigned in accordance with the seventh and eighth editions of the AJCC staging system, as well as according to a modified system with T status definition combining extrapancreatic invasion and tumour size. Patients were then stratified by receipt of adjuvant therapy. Survival analysis and multivariable interaction analysis of adjuvant therapy with pathological parameters were performed. The results were validated in an external cohort from the USA.

Results
The developmental set consisted of 389 patients, with a median survival of 34.6 months. The modified staging system displayed the best prognostic stratification and the highest discrimination (C-index 0.763; 1-, 2- and 3-year time-dependent area under the curve (AUC) 0.746, 0.722, and 0.705; Uno’s AUC 0.710). Overall, 67.0 per cent of patients received adjuvant therapy. There was no survival difference by receipt of adjuvant therapy (35.0 versus 36.0 months; P = 0.772). After multivariable adjustment, interaction analysis suggested a benefit of adjuvant therapy for patients with nodal metastases or with tumours larger than 2 cm with extrapancreatic extension, regardless of nodal status. These results were confirmed in the external cohort of 216 patients.

Conclusion
Modified staging with a T status definition combining extrapancreatic invasion and tumour size is associated with better prognostic segregation after postneoadjuvant pancreatectomy. This system allows identification of patients who might benefit from adjuvant therapy.

Published: June 2023

Abstract
To mitigate the structural and institutional biases that contribute to inequities in health, we need a diverse cadre of individuals to feel included and advance within our field in order to bring a multicultural set of perspectives to the studies we conduct, the science we generate, the health and academic systems we design, and the medical and scientific knowledge we impart. There has been increasing focus on diversity, inclusion, and equity in recent years; however, often these terms are presented without adequate precision and, therefore, the inability to effectively operationalize inclusion and achieve diversity within organizations. This narrative review details several key studies, with the primary objective of presenting a roadmap to guide defining, measuring, and operationalizing inclusion within work and learning environments.
