Published: September 2024

Abstract

As global climate change becomes increasingly severe, pollution reduction and carbon mitigation have become particularly important. At present, various industries and sectors are actively engaged in pollution reduction and carbon mitigation efforts, but their effectiveness remains unclear. There is currently a lack of technology that can provide effective indication and guidance for pollution reduction and carbon mitigation efforts across different industries and sectors, leading to difficulties in systematizing and refining control measures. To address this, this paper constructs a correlation model between sectoral electricity consumption and average carbon column concentration in cities by utilizing large-scale, multi-period electricity consumption and average carbon column concentration data, and employing random forest, XGBoost, and stacking regression methods. By integrating time rolling window techniques, the model reveals the dynamic temporal relationship between electricity consumption and carbon concentration, thereby providing guidance and indications for pollution reduction and carbon mitigation efforts. To ensure the reliability of the model, this study collected categorized electricity consumption data and regional average carbon concentration data from 6 cities over a five-year period from January 2017 to December 2021. The performance of the correlation model was evaluated using indicators such as R² and RMSE. The results show that in most cities, the model has high explanatory power and low prediction error, with the highest R² of the stacking model reaching 0.8528 and the root mean square error (RMSE) being 1.4939. To further analyze the dynamic temporal impact relationship between sectoral electricity consumption and average carbon column concentration in cities, this paper also calculates the correlation of sectoral electricity consumption in different time periods for each city through time rolling analysis, revealing the main sectoral factors influencing the rise in urban carbon concentration over different time intervals. This provides valuable insights for grid management and energy policy planning. This study not only provides a scientific basis for assessing and guiding pollution reduction and carbon mitigation efforts in various industries but also offers important reference value for policymakers and industry managers, helping to formulate more effective emission reduction strategies and energy management measures.
Excited-State Reaction Dynamics of the Radical Anions Revealed by the Novel Time-Resolved Photofragment Depletion Spectroscopy
Authors: kim Sang Kyu , An Sejun 
Published: September 2024

Abstract

xcited-state reaction dynamics of the radical anions have been investigated by a newly-developed time-resolved photofragment depletion (TRPD) spectroscopy where the different photodetachment cross-sections of the various anionic species during the reaction process were utilized to unravel their overall temporal evolutions. The otherwise formidable interrogation of the excited-state reaction dynamics of the radical anions, primarily due to the fact that their excited-states are often located above the electron detachment threshold, could be realized here. The shape of the excited-state potential energy surface of I2- has been clearly manifested in the TRPD transients taken at several different probe wavelengths, whereas the ultrafast internal conversion from the optically-excited nonvalence-bound state into the ground or excited valence-bound states of CH3NO2- or (CH3NO2)2-, which is followed by the fast chemical bond dissociation or the rather slow cluster decomposition, has been experimentally investigated for the first time to uncover the overall mechanism of the electron transfer dynamics among different (non)valence orbitals.
Embedded Complexity and Quantum Circuit Volume
Authors: Ma Xiongfeng , Du Zhenyu , Liu Zi-Wen 
Published: September 2024

Abstract

Quantum circuit complexity is a pivotal concept in quantum information, quantum many-body physics, and high-energy physics. While extensively studied for closed systems, the characterization and dynamics of circuit complexity are little understood for the situation where the system is embedded within a larger system, which encompasses measurement-assisted state preparation. To address this gap, we introduce the notion of embedded complexity, which accounts for both system extensions and measurements. We study the complexity of projected states in a subsystem after measuring its complement and find that in random circuits, the embedded complexity is lower-bounded by the circuit volume---the total number of gates affecting both the subsystem and its complement. This finding indicates that the total cost of preparing the projected state cannot be reduced by leveraging ancillary qubits and measurements in general. Our result underscores the operational meaning of circuit volume, as it characterizes the embedded complexity of the generated state. Specifically, for random circuits or Clifford circuits, we demonstrate a spacetime conversion that concentrates circuit volume onto a subsystem via a random gate teleportation approach. In scenarios of deep thermalization where the system interacts extensively with a larger system, our analysis suggests that the resulting projected states exhibit high complexity. Additionally, we introduce a shadow tomography protocol that employs only ancillary random states and Bell state measurements, circumventing the need to evolve the input state and thereby simplifying experimental controls.
Level of Client Satisfaction With Contraceptive Counseling and Associated Factors Among Women Attending Family Planning Services in Public Hospitals Addis Ababa 2022
Authors: Getaneh Chala 
Published: September 2024

Abstract

Background: - Contraceptive counselling is a type of client-provider interaction that involves two-way communication between a health care staff member and a client for the purpose of confirming or facilitating informed decision by the client, or helping the client address problems or concerns.. Effective contraceptive counselling is one of the cornerstones for increasing family planning acceptance. The best decisions about family planning are those that people make for themselves based on accurate information and a range of contraceptive options. Otherwise they can either deny the service or discontinue the method if they are not properly counselled on minor side effects and myths related to the method. It empowers people to exercise their right to good quality family planning care
Objectives: To assess the level of client’s satisfaction with contraceptive counselling and associated factors among reproductive age women in Addis Ababa Ethiopia 2022.
Methods: -Institutional based cross-sectional study was used and multi-stage sampling technique was employed to recruit 592 participants. Structured and pretested questionnaire was used to collect data. Data was analysed using SPSS version 26. Descriptive statistic was used to summarize Socio-demographic and health related factors.

Authors: Hassan Javerya 
Published: September 2024

Abstract

Background: Mortality risk assessment is vital for preoperative risk evaluation and resource allocation. This article presents a single-centered comprehensive analysis of Society of Thoracic Surgeons (STS) scores and factors impacting outcomes in cardiothoracic surgery patients. It aims to assess the STS risk score's effectiveness in predicting mortality.
Methods: STS scores for a diverse patient cohort of 3084 patients who underwent cardiac surgery between January 2010 and December 2016 at a Tertiary care Hospital, in a low-middle income country . Statistical methodologies, such as the chi-square test, Fisher's exact test, independent sample t-test and Mann-Whitney U test were applied. Univariate and multivariate analysis were also executed.
Results: Demographics analysis showed the mean age of study population was 58 years. The predominance of males and the most common procedures were isolated Coronary Artery Bypass Graft (CABG), MVR, and AVR. Hypertension and diabetes were the most prevalent comorbid conditions, with a family history of CAD found in 46.7% of the patients. Mortality rates were higher for females, the elderly, those with mitral insufficiency and patients on ADP inhibitors for anticoagulation. Post-operative complications, including dialysis, stroke, prolonged ventilation and length of stay, were linked to higher mortality. The threshold value of STS was found to be ≥ 1.645 indicating a high-risk group with a 10.3% mortality rate. This threshold had a sensitivity of 74.5% and specificity of 78.2%, contributing to an accuracy of 78.08%.
Conclusion: STS risk calculator is a great tool for mortality prediction in our country with an AUC value of 0.819 (95% CI 0.791-0.898).
Research on a zero water consumption operation model and feasibility for office buildings

ABSTRACT
According to Taiwan's government policy on net zero emissions by 2050, building designs are moving toward zero energy and zero water consumption to achieve these goals. Among these goals, establishing an independent water cycle within building systems is a primary objective. The present study examined office buildings as the research subject due to their crucial water usage characteristics, which can serve as a reference for other building types. We developed a water-use estimation model by conducting a literature review and data collection from existing green office building cases in Taiwan. The methods involved calculating the median annual water consumption per unit building area and discussing the current water-saving design status and water-saving rate. The findings indicate a median water-saving rate of 53%, which is far short of the goal of achieving a zero water building. This finding is primarily attributed to the infrequent use of water compensation in building designs. The feasibility of a zero water building is validated and determines its crucial operation. Consequently, design engineers can employ this methodology to compute water conservation rates for their designs, aiming for the construction of a zero water consumption building.

ABSTRACT

Algal bioremediation using macroalgae is a promising approach to wastewater treatment. This study compared the productivity and bioremediation performance of the freshwater filamentous algal cultivars; Klebsormidium flaccidum, Oedogonium calcareum, and Oedogonium sp., in primary municipal wastewater in outdoor high-rate filamentous algal pond mesocosms. K. flaccidum had the highest biomass productivity (3.09 g dry weight m−2 day−1 ± 0.20 SE) and bioremediation performance, reducing total ammoniacal-N by 51% to 14.80 mg L−1 (± 0.81 SE), nitrate-N by 59% to 0.30 mg L−1 (± 0.02 SE), and dissolved reactive phosphorous by 15% to 3.52 mg L−1 (± 0.07 SE). This cultivar achieved the greatest reductions in total suspended solids (54%), carbonaceous biochemical oxygen demand (93%), and chemical oxygen demand (74%). K. flaccidum and Oedogonium sp. reduced Escherichia coli by 98%. Competitive dominance of K. flaccidum and Oedogonium sp. was assessed in bicultures at three stocking densities. By day 12, K. flaccidum's proportion increased from 50 to 64% (± 6.1 SE) and 73% (± 5.0 SE) at a stocking density of 0.25 g and 0.5 g FW L−1, respectively. Based on superior biomass productivity, bioremediation performance, and competitive dominance, K. flaccidum was identified as a target cultivar for bioremediation of primary municipal wastewater.

Published: September 2024

This study was aimed to determine the in vitro antioxidant potential of biochanin A (BCA), an isoflavone phytochemical, by using various free radical scavenging assays. The free radical scavenging activity of BCA was evaluated by various standardized assays such as 1, 1-Diphenyl-2-Picryl Hydrazyl (DPPH●), 2, 2’-Azinobis-3-Ethylbenzothiazoline-6-Sulfonic Acid (ABTS●+), Ferric Reducing Antioxidant Power (FRAP),nitric oxide scavenging activity, reducing ability, hydroxy radical activity, superoxide anion scavenging activity, hydrogen peroxide radical, metal ion chelating activity and phosphomolybdenum assay. Four different concentrations of BCA (5, 10, 20, 40, μg/ml) were taken for evaluating the scavenging activity and which were compared with the antioxidant activity of standard ascorbic acid (AA). BCA showed good free radical scavenging activity, which was calculated as IC50. IC50 value of BCA was also comparable to Ascorbic acid (AA).Whereas AA was used as a standard. The scavenging activity of BCA was significantly elevated in a dose dependent manner. The BCA was exhibited a highest scavenging activity than the standard. The results obtained in the present study revealed that the BCA is an excellent free radical scavenger with the activity similar to that of AA.

How Auditors’ Client Service Affects Managers’ Cooperation with Auditor Evidence Requests
Authors: Hatfield Richard C. , Hoang Kris , Ricci Michael A. , Thomas Edward 
Published: September 2024

SUMMARY
Audit quality is threatened when client managers are uncooperative (i.e., slow to provide evidence or not forthcoming with evidence). We examine whether auditors can increase client manager cooperation by providing better client service in their day-to-day interactions with client managers. For example, auditors can provide better client service by minimizing disruptions and communicating effectively. Across two experiments, we find that managers experiencing better client service respond timelier to auditor requests and are more forthcoming with evidence, including evidence that contradicts their preferred accounting position. Our findings suggest that auditors can use client service strategically to increase access to information, but anecdotal interviews with experienced auditors suggest that these strategic benefits are not at the forefront of auditors’ minds. Together, our study informs practice by illuminating strategic benefits of better client service and complements prior research which focuses on how service-related constructs can benefit auditors commercially and when negotiating with clients.

Published: September 2024

ObjectivesTo examine the costs and predictors of high hospital use and criminal reoffending in adults experiencing homelessness.
ApproachRetrospective cohort study of 2,140 adults who attended homeless hostel clinics in New South Wales, Australia using linked clinic, health, criminal offence, and mortality data from 1 July 2008 to 30 June 2021. Multivariable logistic regression examined predictors of high all-cause hospital use (≥4 emergency department presentations in 12 months) and predictors of recidivism.
ResultsThere were 27,466 hospitalisations at a total cost of AUD$548.2 million. Twenty-seven percent of the cohort had high hospital use. Factors associated with high use were age ≥45 years, female (AOR: 1.52; 95%CI 1.05-2.22), presence of a mental disorder, substance use disorder (AOR: 1.36; 95%CI: 1.03-1.82), or being homeless for >1 year (AOR: 1.31; 95%CI: 1.06-1.62). There were 1,646 (76.9%) adults who had contact with the criminal justice system. Most (75.3%) reoffended within 24 months after index offence, and reoffenders were more likely to be younger, have a personality disorder (AOR: 1.31; 95% CI: 1.04-1.67), substance use disorder (AOR: 1.60; 95%CI 1.14-2.23), and had a previous charge dismissed on mental health grounds (AOR: 1.79; 95% CI: 1.31-2.46). Reoffenders more likely to have a principal theft-related offence (AOR: 1.85; 95%CI: 1.29-2.66). Total court finalisation costs were AUD$11.3 million.
ConclusionsThe high use of hospital and criminal justice services lends support to strategies to develop models of supported housing with a focus on integrated care, mental health support, improved referral pathways, and better coordination with community-based support agencies.
