Advanced State Estimation Methods for Lithium-Ion EV Batteries: A Kalman Filter and MLP Hybrid Approach
Authors: S Mohana Devi. , Bagyaveereswaran V. 
Published: November 2024

Abstract

The proliferation of electric vehicles has advanced battery technology; yet safety concerns have emerged related to mechanical, electrical, or thermal problems. An effective Battery Management System is crucial for enhancing battery performance, particularly regarding State of Charge and State of Health. Research has concentrated on examining sensor malfunctions in batteries to avert problems such as overcharging and overheating. Techniques like as voltage measurement, coulomb counting, and Kalman filtering are employed for state of charge estimate. To overcome these limitations, the proposed work utilizes the Extended Kalman Filter (EKF), which can handle the non-linear characteristics often exhibited by sensor readings and fault behaviours. The EKF algorithm involves initialization, prediction, and correction phases, allowing for accurate state estimation based on measurements. For SOH estimation, the NASA battery dataset, which includes various battery conditions across different temperatures, is analysed using a modified Multi-Layer Perceptron (MLP) regression process. This modified MLP employs a gradient shift bias adjustment technique to minimize error rates, effectively adjusting the model's weights for better SOH estimation. The findings demonstrate enhanced performance in State of Charge (SOC) and State of Health (SOH) estimates for Root Mean Square (RMS) and Mean Squared Error (MSE).

Abstract

Purpose:
To quantitatively investigate the pathological subtypes of lacrimal gland adenoid cystic carcinoma (LGACCs), the tumor immune microenvironment in each pathological subtype, and the relation to survival.
Methods:
In this retrospective study, the tumor subtype was determined by H&E staining. Multiplex immunochemistry was performed to define specific immune cells. The tumor immune microenvironment (TIME) was sketched by sequential image scanning and reconstructed by a cytometry platform.
Results:
Thirteen patients of LGACCs showed a mixture of different pathological subtypes with varied percentages. The cribriform was the most common subtype, taking an overall percentage of 39%. The rest of the pathological subtypes were tubular (19%), basaloid (17%), cribriform and tubular mixture (C+T) 14%. The sclerosing and comedocarcinomic subtypes were the least seen in LGACC, taking a percentage of 11% altogether. Patients with cribriform dominant component had better overall survival than the non-cribriform dominant patients. Patients with basaloid dominant component had worse clinical outcomes than the non-basaloid dominant ones. The TIME showed high immunogenicity in the tumor margin but declined in the tumor areas. Pathological subtypes rather than individual differences determined the TIME phenotype. The cribriform subtype possessed more immune cell infiltration than other pathological subtypes.
Conclusions:
LGACC is composed of multiple subtypes with different percentages, which is related to the prognosis. TIME pattern in LGACC varied among different pathological subtypes, which could indicate novel strategies in immunotherapy.
Statistical sedimentary aspects of collapsed volcanic edifices along Pacific subduction zones.
Authors: bernard karine 
Published: November 2024

Abstract

Using Google Earth imagery and published data on volcanoes worldwide, several examples of volcanic debris avalanche deposits have been compared to characterize the dynamics of mass flow and matrix transformation during glacial and interglacial periods. Sedimentological studies of these deposits help to correlate the spatial and temporal distribution of collapsed edifices with the stratigraphy and textural variations of the matrix. Parameters such as percentage of matrix, mean grain size, ratio of matrix sand to gravel and other statistical sedimentary parameters have been calculated to characterize the matrix breccias in relation to the spatio-temporal variability of the mass flow deposits. Factors such as quaternary erosion, nival surface conditions and high intensity rainfall contribute to the transformation of the reworked avalanche deposits into debris flows. The sedimentary characteristics of volcanic debris avalanche deposits are influenced by the profile shape, volcanic area and slope gradient of the collapsed edifices, which are related to the critical stability and quaternary cyclic evolution of the stratovolcanoes. Empirical equations have been developed to propose a co-genetic evolution of volcanic avalanche deposits in terms of their spatio-temporal distribution, morphological variations of the collapsed edifices, and climatic changes. Similar correlations between quaternary occurrence, matrix percentage, matrix/gravel ratio, and median grain size show a positive association with the obliquity of the Earth's axis and the precession of the equinoxes. These results highlight the importance of semi-quantitative sedimentological analyses of deposits from collapsed volcanic edifices in refining our understanding of subsequent hazardous flows .

Published: November 2024

Abstract

Purpose: Recent evidence indicates that the consolidation tumor size of part-solid adenocarcinoma does not have prognostic value unlike that of pure-solid adenocarcinoma. We aimed to analyze the impact of consolidation tumor size on postoperative survival in part-solid adenocarcinomas.
Methods: This retrospective study analyzed data of 375 patients with part-solid adenocarcinomas who underwent surgery at our institute between 2006 and 2021. The patients were grouped into the low (>0–≤0.5, n=187) and high (>0.5 to <1, n=188) consolidation-to-tumor ratio groups. Clinical characteristics and survival stratified by consolidation-to-tumor ratio were analyzed using propensity score matching for consolidation tumor size.
Results: A larger consolidation tumor size significantly correlated with higher consolidation-to-tumor ratio (r2=0.56, P<0.0001) and larger pathological invasive size (r2=0.41, P<0.0001). Male sex and high consolidation tumor size were significant negative risk factors for overall survival in the unmatched cohort. The 5-year overall survival rates in the low/high consolidation-to-tumor ratio groups were 95.2%/85.2% (P=0.008), respectively, in the unmatched cohort and 93.0%/83.2% (P=0.10), respectively, in the matched cohort, demonstrating a diminished significant survival difference.
he result of the competing risk analysis using the cumulative incidence of cancer or non-cancer death curves. The 5-year cumulative incidence of cancer-death rates were 0% (95% CI, NA–NA) and 5.57% (95% CI, 2.10–11.70) in the low and high CTR groups, respectively, with significant difference (P=0.01). In contrast, the 5-year cumulative incidence of non-cancer-death rates were 4.72% (95% CI, 1.40–11.10) and 9.44% (95% CI, 4.50–16.50) in the low and high CTR groups, respectively, with no significant difference (P=0.18). These results indicate a significant difference in cancer mortality the between the two groups.
Conclusions: The consolidation tumor size may affect overall survival and possibly reflect tumor growth activity, being consistent with TNM 8th edition, in part-solid adenocarcinomas.

Published: November 2024

Abstract

Adolescent pregnancy in Ethiopia is a major health concern because of its association with higher morbidity and mortality for both mother and child. The purpose of this study was to investigate resilience and social influences in proactively preventing adolescent pregnancies among high school adolescents. A quantitative cross-sectional survey was conducted using adolescent resilience questionnaires (ARQ) in two systematic selected high schools in Ethiopia. Statistical analysis of the completed 790 adolescent resilience questionnaires (ARQ) was done using Statistical Package for Social Sciences software (SPSS) version 23. The study results showed high scales ranking of (< 50%) by respondents on 80% of social influences dimensions pertaining to the family, peers, school and the community in terms of their availability, non-availability, connectedness or not connected. High scores of social influences correlated with high levels of resilience in adolescents. Multivariate logistic regression showed adolescents who are 18–19 years of age and school grade 11 more likely to demonstrate resilience (p < 0.05). The study suggests that adolescents with enough community support and self-assurance are likely to become resilient when faced with hardships.
A validated score to predict risk of severe weight loss in amyotrophic lateral sclerosis
Authors: Lester David G , Talbot Kevin , Turner Martin R , Thompson Alexander G 
Published: November 2024

Abstract

Background
Severe weight loss is common in amyotrophic lateral sclerosis (ALS) and associated with shortened survival. The ability to predict risk of severe weight loss from baseline clinical variables would enable targeted nutritional support.
Methods
This retrospective longitudinal clinical cohort study used data from a multi-centre ALS clinical trials repository (N=3,289 patients) to develop time-to-≥10% weight loss Cox proportional hazards and random survival forest models, which were then tested in validation data from a multi-centre ALS clinical resource (N=298) and a referral-based regional clinic (N=104). Predictor variables were recorded at time of first weight measurement: age, gender, time from symptom onset, diagnostic latency, onset site, body mass index, forced vital capacity (FVC), and Revised ALS Functional Rating Scale (ALSFRS-R) subscores. The most important variables from the most accurate model were used to create a simple weight loss risk score.
Results
The random survival forest outperformed the Cox proportional hazards model in validation data (concordance index=0.67). The two most important variables from the random survival forest– ALSFRS-R bulbar subscore and FVC– were used to create a weight loss risk score that categorised patients using these two baseline clinical variables into low (score=0), intermediate (score=1) and high (score=2) risk of ≥10% weight loss. Analysis of weight loss risk score as a continuous parameter by Cox regression in validation data demonstrated a significantly increased risk of severe weight loss with each point increase (HR 1.83, 95% CI 1.44-2.32, p<0.01).
Conclusions
Weight loss in ALS is associated with a combination of bulbar and respiratory dysfunction. A simple score identifies risk of severe weight loss for potentially more targeted support.

Abstract

Background: The purpose of this study was to investigate the effects of subendometrial PRP injection on endometrial thickness and pregnancy outcomes in patients with a history of unresponsive thin endometrium undergoing frozen-thawed embryo transfer (FET). Methods: This prospective cohort study was conducted at a Acibadem Mehmet Ali Aydinlar University-Istanbul, Turkey. Women with a history of suboptimal endometrial proliferation (< 7 mm) were offered to participate in the study. Those who accepted subendometrial PRP injection formed Group 1 (n = 100); those who did not accept PRP injection formed the control group (Group 2; n = 100). Autologous PRP was prepared by centrifugation from peripheral blood and was injected transvaginally into the subendometrial region under ultrasound guidance within 10 days of the cessation of the menstruation. On the 2-4th days of the second menstrual cycle after the PRP procedure, hormonal treatment was initiated with 14 days of oral estradiol supplementation. Embryo transfer was scheduled for women who were found to have adequate endometrial thickness after the initiation of progesterone. Pregnancy (positive serum hCG) and livebirth rates were followed.
Results
A total of 200 women (age 36.4 ± 5.8) were included in the study. PRP treatment resulted in higher endometrial thickness compared to the control group (7.7 ± 1.9 mm vs 6.1 ± 1.2 mm; p < 0.01). In the PRP group, 3 women (3.0%) conceived spontaneously and 97 (97.0%) attempted FET; in the control group there were no spontaneous pregnancies. In the PRP group, 33/97 women (34.0% of total) could not undergo ET due to persistent unresponsive thin endometrium or fluid in the endometrial cavity, compared to 75/100 (75% of total) in controls (p < 0.001). Positive serum hCG test was significantly higher in the PRP group compared to the control group (25.8% vs 9.0%; p = 0.002). Clinical pregnancy rate was also higher in the PRP group (22.7% vs. 7.0%; p = 0.002). Live birth rate was significantly higher in the PRP group compared to the controls (17.5% vs. 2.0%; p < 0.001).
Conclusions
In women with a history of suboptimal endometrial development, subendometrial PRP injection was associated with improved endometrial thickness and livebirth rate.

Comparison of K-wires and adjustable external fixation after closed osteotomy in the treatment for cubitus varus in children
Authors: Yao Jia Qi , Du Ying Jie , Ji Feng Kun , Chen Hui , Wang Zhen Dong , Liu Li , Zhou Hui Xia , Li Wen Chao 
Published: November 2024

Abstract

Background
Cubitus varus deformity is commonly regarded as a late complication of supracondylar humeral fractures in children. This retrospective study aimed to compare the outcomes of K-wires and adjustable external fixation in the treatment of cubitus varus deformity.
Methods
The study included 26 patients with cubitus varus deformities secondary to supracondylar fractures between January 2016 and December 2023. All patients were treated with closed osteotomy and K-wire fixation (n = 14) or adjustable external fixation (n = 12). Clinical data, including carrying angle, vascular and neurologic examination, and range of elbow motion, were recorded and analyzed. Functional outcomes were assessed using the Mayo Elbow Performance Score (MEPS) and Bellemore criteria at the last follow-up.
Results
The average follow-up period was 14.91 months for the K-wire group and 16.14 months for the external fixation group. There were no significant differences in age, gender, mean surgery time, mean union time, carrying angle, or arc of motion between the two groups (P>0.05). No cases of nonunion, myositis ossificans, or recurrence of deformity were observed at the last follow-up. The mean union time for cubitus varus deformity was 7.83 ± 1.19 weeks in the external fixation group and 8.85 ± 1.02 weeks in the K-wire group, with a significant difference in union time following closed osteotomy (P = 0.0271). However, there was no statistically significant difference in functional outcomes between the two groups according to the MEPS (P>0.05).
Conclusions
Both K-wires and external fixation following closed osteotomy are effective for treating cubitus varus deformity in children. Adjustable external fixation increases compression at the osteotomy site, promoting faster union and providing stability in the lateral cortex, which reduces the risk of injury to the cubital nerve compared to K-wires. Additionally, the hinge of the external fixation can be adjusted to maintain the correct angle of the distal articular surface of the humerus.

Abstract

Addressing the opioid overdose crisis requires both increasing the adoption of evidence-based practices (EBPs) and ensuring that EBPs reach individuals at high risk for opioid overdose death and population groups disproportionately burdened by fatal overdose. It is important to culturally adapt EBP strategies to reach these populations and to monitor the impact of these strategies.
The HEALing Communities Study engaged coalitions in 67 communities across four states in the Communities That HEAL intervention to select and implement EBPs to reduce opioid overdose mortality. Coalitions were encouraged, but not required, to culturally adapt strategies for “special populations.” EBP strategies were documented in coalition action plans.
The research team developed a data collection tool to capture quantitative and qualitative details from coalitions’ action plans. A standard operation procedure provided guidance on how to characterize cultural adaptations to reach special populations. Following the first wave of the intervention (January 2020 – June 2022), the research team utilized the DATA (Describe, Analyze, Theorize, and ACT) model for reflective practice in evaluation. Authors met to Describe efforts to reach special populations and each site’s approach to Analyzequantitative and qualitative data; to Theorize about how to improve data collection; and to identify Actions to better develop and document EBP cultural adaptation strategies in future studies.
This manuscript presents examples of culturally adaptedEBP strategies designed to address the needs of multiple special populations in the first wave of the HEALing Communities Study. We share lessons and practical tips for designing, documenting, and monitoring cultural adaptation strategies.

Tarnishing and Pitting Corrosion Mechanism Revealed by Nanoparticles on the Gold Foil of Western Han Dynasty in Taiyuan, Shanxi, China through a Multi-analytical Approach
Authors: Gong Zisang , Sun Siyuan , Hu Pei , Pei Jingrong , Hu Gang 
Published: November 2024

Abstract

To figure out optical and corrosion mechanism of tarnishing and pitting corrosion of the archaeological gold foil, ESEM-EDS, XRD, XPS were used to obtain chemical composition of different depths and observe surface topography. The results show Ag is enriched on the surface, mainly as Ag2O nanoparticles, and Au is enriched internally due to the selective corrosion of Ag. Optical mechanism of gold tarnishing is surface plasmon resonance (SPR) of Ag2O nanoparticles. The colour darkens as nanoparticle size increases. Flaming in the atmosphere results in accelerated oxidation of Ag and edge-off, leading to electrochemical crevice, pitting corrosion and perforation during burial.

Abstract

O3-type cathodes for sodium-ion batteries have attracted significant attention owning to their low cost and high energy density. However, their applications are restricted by rapid capacity degradation during long-term cycling, with uneven Na+ distribution and microcrack formation being key contributing factors. In this study, a customized reconstruction layer integrating a fast ion conductor NaCaPO4 coating with gradient Ca2+ doping was developed to enhance the surface chemical and mechanical stability of the layered cathodes. The gradient Ca2+ doped interphase facilitated uniform phase transformation within the particles, minimized lattice mismatch, ensured even Na+ distribution, and mitigated microcrack formation through a pinning effect. Consequently, the optimized cathode delivered excellent rate performance (105.3 mAh g− 1 at 10 C), long-term cycling stability (81.0% capacity retention after 300 cycles at 0.5 C), and robust reliability under high-voltage conditions and across a wide operating temperature range (− 10 to 50°C). The practical feasibility of a pouch-type Na-ion full cell paired with a hard carbon anode was demonstrated by a high capacity retention of 82.9% after 300 cycles at 1 C. This scalable interface modification strategy can provide valuable insights into the development of advanced oxide cathode materials for sodium-ion batteries.

Published: November 2024

Abstract

Integrated Energy Systems (IESs) with hydrogen storage typically generate a large amount of data when the time resolution is high and the planning horizon is long. Making use of the nature of data in the case study provided by the 16th AIMMS-MOPTA competition, a full and a compact version of a Mixed Integer Linear Programming (MILP) model were formulated with an objective of minimizing the total investment cost of the system components. The full and compact models were tested with different time-slot aggregations, finding that the latter provided a significant computational improvement over the former. Taking advantage of the computational efficiency of the compact model, we analyzed the trade-offs of the resources by applying different upper bounds to the power generation capacities. Furthermore, we introduced a stochastic approach to account for the intermittency of wind and solar resources. The optimal system produced by our method is capable of supplying electricity and hydrogen demand of the case study at a minimum cost with a realistic security of supply level.
