Online Information-Based Product Evolution Course Mining and Prediction
Authors: Chen Yuh-Jen , Chen Yuh-Min
Published: February 2023

In today’s fiercely competitive business environment, product design and development play critical roles in an enterprise’s success; therefore, consumer demand must be understood. Enterprises used to understand their consumers’ demands through time-consuming questionnaire surveys and statistical analyses. As the Internet and the popularity of virtual communities have grown, more consumers are leaving comments about their perceptions of the appeal of products on online social media platforms, thus enabling enterprises to more objectively understand consumers’ product preferences and demands. Therefore, determining how to effectively assist enterprises in analyzing valuable information beneficial to product design and development that can be gleaned from the large amount of social media data available is critical to promoting an enterprise’s competitive advantage in the product market. However, previous studies have primarily focused on understanding consumer viewpoints of products through review articles or electronic word-of-mouth (eWOM; it is a common channel for spreading product appraisals) from online social media. For these review articles and eWOM that can imply consumer demand for product features, there were no relevant studies focused on analyzing consumer demand by using both online review articles and eWOM for product feature evolution. Therefore, for new product features, this study developed a mechanism for product evolution course mining from product-related review articles (such as product functions or specifications) and eWOM on online social media to realize the prediction of future product features or specifications, and then assist enterprises in rapidly and accurately grasping product development trends to effectively discern key reference information for product design and development. The study was achieved by (1) designing a process for online information-based product evolution course mining and prediction, (ii) developing techniques related to online information-based product evolution course mining and prediction, and (iii) implementing and evaluating an online information-based product evolution course mining and prediction mechanism. The experimental results indicated that approximately 81% of developers were satisfied with the proposed system for predicting smartphone features. The results of the study can facilitate the mining and prediction of online information-based product evolution course to assist enterprises in rapidly and accurately grasping product development trends and effectively provides important reference information for product design and development; therefore, it can enhance competitive advantages and customer satisfaction of enterprise products in the marketplace.

Published: February 2023

Fuzzy set theory has attracted many researchers’ interests and many efficient variants have been implemented in support system, decision-making and other fields. Inspired by the idea of variable weight analysis, in this study, we investigate state variable weight vector and its properties, propose two kinds of variable weight aggregation operators such as variable weight averaging (VWA) operator and variable weight geometric (VWG) operator based on three types of fuzzy attribute values. Finally, we apply in ship evaluation and economy collaboration evaluation tasks and make comparison analysis to illustrate the effectiveness of our proposed technique.
Exploring quantum properties of bipartite mixed states under coherent and incoherent basis
Authors: Roy Sovik , Bhattacharjee Anushree , Radhakrishnan Chandrashekar , Ali Md. Manirul , Ghosh Biplab
Published: February 2023

Quantum coherence and quantum entanglement are two different manifestations of the superposition principle. In this paper, we show that the right choice of basis to be used to estimate coherence is the separable basis. The quantum coherence estimated using the Bell basis does not represent the coherence in the system, since there is a coherence in the system due to the choice of the basis states. We first compute the entanglement and quantum coherence in the two-qubit mixed states prepared using the Bell states and one of the states from the computational basis. The quantum coherence is estimated using the [Formula: see text]-norm of coherence, the entanglement is measured using the concurrence and the mixedness is measured using the linear entropy. Then we estimate these quantities in the Bell basis and establish that coherence should be measured only in separable basis, whereas entanglement and mixedness can be measured in any basis. We then calculate the teleportation fidelity of these mixed states and find the regions where the states have a fidelity greater than the classical teleportation fidelity. We also examine the violation of the Bell-CHSH inequality to verify the quantum nonlocal correlations in the system. The estimation of the above-mentioned quantum correlations, teleportation fidelity and the verification of Bell-CHSH inequality is also done for bipartite states obtained from the tripartite systems by the tracing out of one of their qubits. We find that for some of these states’ teleportation is possible even when the Bell-CHSH inequality is not violated, signifying that nonlocality is not a necessary condition for quantum teleportation.

Published: February 2023

The collection of subgraphs of a graph [Formula: see text] containing [Formula: see text] and the null graph [Formula: see text], which is closed under union and intersection, is said to be a graph topology defined on [Formula: see text]. In this paper, we investigate the idea of spanning graph topology of a graph [Formula: see text], where we consider the collection of spanning subgraphs of [Formula: see text] satisfying the axioms analogous to the axioms of graph topology. We begin with the basic concepts of spanning graph topological space and later and introduce two spanning subgraph complements to define closed graphs in spanning graph topological spaces.

Authors: Kulshrestha Sunanda , Goel Anjana
Published: February 2023

Skin cancer is one of the most aggressive forms of cancer found in the world’s population. Due to the increase in exposure to UV rays, pollutants accompanied by environmental disturbances and chemicals present in cosmetics, the rate of skin cancer is increasing with the passing days as per the reports by WHO. The contemporary methods used for skin cancer treatment include chemotherapy, immunotherapy, radiotherapy, surgical methods, etc. but, with the advancement in the field of nanoparticles, skin cancer is also managed with the help of some nanodrugs. Nanoparticles exhibit synergistic effects and encase a lot more properties as compared to contemporary treatments. The advantage of systemic and targeted drug delivery approach has been served well by the nanoparticles in case of skin cancer where the skin is a challenging barrier to cross. Nanoparticles have been successful in the bench to clinical trials for ex 5-FU and many other herbal nanoparticles have been patented and are in the clinical trials phase. Nanoformulations are composed of encapsulated drugs that have high stability, controlled drug release, minimal toxic effects and can easily pass through biological barriers. This paper gives a panoramic view of the recent developments in the field of nanoparticle drug delivery which has revolutionized the paradigm of topical drug delivery in patients with skin cancer.
Understanding the Low-Voltage Behavior of Stoichiometric Over Lithiated Spinel Li1+xNi0.5Mn1.5O4: An Electrochemical Investigation
Authors: Jobst Nicola Michael , Mancini Marilena , Hölzle Markus , Wohlfahrt-Mehrens Margret , Axmann Peter
Published: February 2023

Nickel manganese spinel LiNi0.5Mn1.5O4 is one of the most promising candidates for next-generation cobalt-free active materials for cathodes in lithium-ion batteries. Despite the relatively low specific capacity of 147 mAh g−1, its high operating voltage of 4.7 V leads to a high specific energy of 690 Wh kg−1. By extending the operating voltage range from 3.0–4.9 V down to 1.5 V it is possible to access a lithiation degree up to x = 2.5 and a theoretical specific capacity of 346 mAh g−1. However, this causes pronounced capacity fading. Typical voltage profiles show unexpected additional step at about 2.1 V, which cannot be explained by open circuit measurements. We applied several electrochemical methods to investigate the lithiation of highly-ordered, stoichiometric spinel at low-voltages. Mixed potential measurements provided a comprehensive explanation for the low-voltage behaviour and supports interpretation of diffusion coefficients, rate capability tests, discharge at different temperatures and impedance spectroscopy. We show that anodic and cathodic partial reactions within the electrode can explain the presence of the additional 2.1 V step. This is caused by the kinetically favoured formation of the phase Li2.5Ni0.5Mn1.5O4 and the simultaneous re-transformation to the thermodynamically stable phase Li2Ni0.5Mn1.5O4.
Use of Mixed Methanesulfonic Acid/Sulfuric Acid as Positive Supporting Electrolyte in Zn-Ce Redox Flow Batter
Authors: Yu Hao , Pritzker Mark , Gostick Jeff
Published: February 2023

The effect of different positive supporting electrolytes on the performance of a bench-scale Zn-Ce redox flow battery (RFB) has been studied. The effectiveness of mixed methanesulfonic/sulfuric acid, mixed methanesulfonic/nitric acid, and pure methanesulfonic acid has been assessed and compared on the basis of the cyclic voltammetric response for the Ce(III)/Ce(IV) redox couple and galvanic charge-discharge of a bench-scale Zn-Ce RFB. The Ce(III)/Ce(IV) reaction exhibits faster kinetics and the RFB exhibits higher coulombic efficiency and long-term performance over ~40 charge-discharge cycles in the mixed 2 mol/L MSA–0.5 mol/L H2SO4 electrolyte compared to that achieved in the commonly used 4 mol/L MSA electrolyte due to lower H+ crossover and higher Ce(IV) solubility. The coulombic efficiency fade rate in the mixed MSA-H2SO4 electrolyte is 0.55% per cycle over 40 charge-discharge cycles, while the fade rate is 1.26% in the case of 4 mol/L MSA. Furthermore, the positive electrode reaction is no longer the limiting half-cell reaction even at the end of long-term battery charge-discharge operation. This work shows that a mixed MSA–H2SO4 acid electrolyte may be a better option for the positive side of a Zn-Ce RFB as a large-scale energy storage device.
Joint Optimization of Planning and Operation for Integrated Electrothermal and Hydrogen Coupling System
Authors: Liu Xiaoou
Published: February 2023

In view of the rough modeling of hydrogen energy system, insufficient analysis of hydrogen energy utilization mode, and the lack of consideration of the multiple uncertain factors, this paper proposes a joint optimization method of planning and operation for integrated electrothermal and hydrogen coupling system (IEHS) based on multiverse optimizer algorithm (MVO) and interval linear programming method. Firstly, the frame structure of IEHS is constructed, and multiple utilization modes of hydrogen energy are analyzed. Secondly, considering the hydrogen physical characteristics, the operation model of high-pressure hydrogen storage device based on Van Deemter equation is established, and the linear model of compressor power consumption is built considering dynamic compression ratio. On this basis, the bilevel optimization model of planning and operation for IEHS is established considering multiuncertainty and multiple hydrogen energy utilization modes. The upper model realizes the capacity configuration of equipment with the goal of minimizing the total construction and operation cost within the service life. The lower model optimizes the output of each equipment with the goal of minimizing the operation cost. The example results show that MVO and interval linear programming method for solving the bilevel optimization model have the better convergence speed and convergence ability. Further, the multiple utilization modes of hydrogen energy can effectively reduce the construction and operation cost of IEHS, and accurately depicting the physical characteristics of the hydrogen storage system can increase the coordination and optimization ability of IEHS. Considering multiple uncertain factors, the optimal configuration scheme and operation cost of IEHS are more stable.

Authors: Zolfaghari Najimeh , Monajemi Ramesh , ShahaniPour Kahin , Ahadi Ali Mohammad
Published: February 2023

The objective of this study was to determine the effect of Trachyspermum ammi (T. ammi) on the liver of streptozotocin (STZ)-induced diabetic rats. This study began by identifying the methanolic composition of T. ammi. The presence of three compounds was determined using gas chromatography-mass spectrometry (GC-MS), with Thymol (60.705%), ϒ-Terpinene (22.216%), and P-cymene (17.078%) being the most prevalent. Afterwards, diabetic rats were treated with T. ammi (200–500 mg/kg) or losartan (20 mg/kg) daily for 60 days. In the diabetic rats treated with T. ammi, levels of hepatic indicators, lipid peroxidation markers, and proinflammatory mediators decreased significantly. In the liver of T. ammi-treated diabetic rats, glutathione-S-transferase (GST), catalase (CAT), and glutathione (GSH) increased significantly. Despite the fact that proinflammatory cytokine levels were significantly increased, interleukin-1β (IL-1β) and tumor necrosis factor-alpha (TNF-α) levels decreased in the groups administered the extract. From these results, it can be concluded that T. ammi significantly restored the liver’s antioxidant balance and inflammation caused by hyperglycemia.

Published: February 2023

Breeding programs in oriental river prawn populations would benefit from a knowledge of heritabilities for growth-related traits to assess their potential for genetic improvement. This study reports the results of heritability estimation and evaluation of epistatic interactions for growth-related traits in oriental river prawn (Macrobrachium nipponense). The results showed that heritability estimates (h2) were low to medium in magnitude, ranging between 0.10 (±0.02) and 0.22 (±0.01) for females and between 0.08 (±0.01) and 0.26 (±0.02) for males. The additive × additive epistasis was directional and synergistic for body weight (growth), body length, and two processing traits (abdominal meat weight and abdominal meat percentage). The presence of biallelic epistasis provides additional new information for the formulation of selection programs. Elimination of some sources of nonadditive effects from phenotypes can lead to more accurate genetic evaluations, and more desirable genetic gains could be achieved through the integration of heritability, additive effects (breeding values), and epistasis in oriental river prawns.
Design and Optimization in MEC‐Based Intelligent Rail System by Integration of Distributed Multi‐Hop Communication and Blockchain
Authors: Tian Linlin , Li Meng , Si Pengbo , Yang Ruizhe , Sun Yang , Wang Zhuwei
Published: February 2023

Mobile edge computing technology has emerged as a novel computing paradigm that makes use of resources close to the devices of the smart rail system. Nevertheless, it is difficult to support data offloading to the stations directly from different trains due to the limited coverage of the stations equipped with MEC servers. Therefore, multi‐hop ad hoc network is considered and introduced in this case. In this paper, an improved architecture is proposed for the MEC‐based smart rail system by blockchain and multi‐hop data communication. The requesting trains can offload the tasks to MEC servers by multi‐hop transmission between trains, even when requesting trains are not covered by servers. Furthermore, we utilize the blockchain technology for the authenticity and anti‐falsification of information during multi‐hop transmission. Then, the offloading routing path and offloading strategy are co‐optimized to minimize both delay and cost of the system. The proposed majorization problem is formulated as a Markov decision process (MDP) and solved by deep reinforcement learning (DRL). In comparison to other existing schemes, simulation results demonstrate that the proposed scheme can greatly improve system performance.
Myo-Inositol Potentiates the Inhibitory Effect of Metformin on Prolactin Levels
Authors: Krysiak Robert , Basiak Marcin , Szkróbka Witold , Okopień Bogusław
Published: February 2023

Introduction: Metformin was found to reduce elevated levels of anterior pituitary hormones. Its thyrotropin-lowering effect was more pronounced in individuals receiving myo-inositol. The aim of the present study was to investigate whether the concomitant supplementation of myo-inositol determines the impact of metformin on prolactin levels. Methods: The study population consisted of two groups of women with mild-to-moderate hyperprolactinemia. Group 1 included 24 individuals receiving myo-inositol preparations (2 g daily for at least 6 months), while 24 inositol-naïve women belonged to group 2. Both groups were matched for age, insulin sensitivity, and prolactin concentration. For the following 6 months, all women were treated with metformin (1.7 daily). Plasma glucose levels, the homeostatic model assessment of insulin resistance ratio (HOMA-IR), glycated hemoglobin, as well as plasma levels of total prolactin, monomeric prolactin, thyrotropin, free thyroid hormones, adrenocorticotropic hormone, and insulin-like growth factor-1 were measured at baseline and after 6 months of metformin treatment. Results: Metformin reduced plasma glucose, HOMA-IR, and glycated hemoglobin in both study groups, but this effect was more pronounced in group 1 than group 2. Treatment-induced changes in total and monomeric prolactin levels were significant only in group 1. There were no differences between follow-up and baseline values of thyrotropin, free thyroxine, free tri-iodothyronine, adrenocorticotropic hormone, and insulin-like growth factor-1. Treatment-induced changes in prolactin concentration correlated with baseline prolactin levels, baseline values of HOMA-IR, and the impact of treatment on HOMA-IR. Discussion: The obtained results suggest that myo-inositol supplementation potentiates the inhibitory effect of metformin on prolactin levels in women with hyperprolactinemia.

Introduction: Hyporesponsiveness to erythropoiesis-stimulating agents (ESAs) affects 10–15% of the chronic dialysis population. We explored baseline characteristics and predictors of ESA hyporesponsiveness in a global randomized cardiovascular outcomes study comparing an investigational hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI), daprodustat, with conventional ESA treatment. Methods: ASCEND-D (NCT02879305) recruited 2,964 chronic dialysis patients receiving ESA treatment (standardized to weekly intravenous [IV] epoetin) who were iron replete at baseline. The primary ESA hyporesponsiveness definition was an ESA Resistance Index (ERI, ESA units/kg/week/hemoglobin g/L) ≥2 or IV standardized ESA dose ≥450 units/kg/week. Predictors of ESA hyporesponsiveness were determined using a multivariable regression model. Alternative hyporesponder definitions were explored. Results: Using the primary definition, 354 (12%) patients were ESA hyporesponsive. Geographic region, notably Latin America, lower baseline body mass index and transferrin saturation, younger age, lower albumin concentration, and a higher baseline IV iron dose were identified as strongly associated (p < 0.001) with ESA hyporesponsiveness. Additional predictors of ESA hyporesponsiveness included female sex (p = 0.010), history of heart failure (p = 0.035), longer dialysis vintage (p = 0.077), smoking status (p = 0.247), aspirin use (p = 0.121), and angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use (p = 0.214). Conclusion: This is the first global HIF-PHI study to report prespecified definitions and predictors of ESA hyporesponsiveness. While most of the predictors identified in our study have been previously reported, geographic region stands out as an unexpected finding, meriting further investigation.

Published: February 2023

Introduction: Primary microcephaly (MCPH) is not an uncommon disorder with multiple etiologies. There are a growing number of MCPH-related genes discovered due to the extensive application of whole-exome sequencing (WES) in clinical and research settings. Biallelic mutations in the SASS6 gene cause an extremely rare MCPH, type 14. To date, only two families with SASS6 gene-related microcephaly have been reported. Case Description: We report a case of recurrent congenital microcephaly in a Chinese family. The two affected fetuses presented with microcephaly early in the second trimester with agenesis of the corpus callosum. In the first affected fetus, trio WES detected two compound heterozygous candidate variants c.1139T>C(p.L380P) and c.1223C>G (p.T408S) in the SASS6 gene. Another affected fetus also inherited both variants, while the normal child carried neither variant through Sanger sequencing analysis. Both variants were classified as a variant of uncertain significance according to the current American College of Medical Genetics and Genomics guidelines. Conclusion: We reported novel biallelic variants in the SASS6 gene, encoding the SAS6 centriolar assembly protein, associated with prenatal onset of autosomal recessive microcephaly. We postulate that the pathomechanism of the compound heterozygous variants in close proximity could potentiate the overall coiled instability leading to the phenotypic features of our case.

Authors: Roehm Bethany , Hedayati Susan , Vest Amanda R. , Gulati Gaurav , Miao Jonathan , Tighiouart Hocine , Weiner Daniel E. , Inker Lesley A.
Published: February 2023

Background

Advanced kidney disease is often a relative contraindication to left ventricular assist device (LVAD) implantation because of concerns for poor outcomes including worsening kidney disease. Data are lacking on long‐term changes and sex‐based differences in estimated glomerular filtration rate (eGFR), with published data limited by potential bias introduced by the competing risks of death and heart transplantation.

Methods and Results

We conducted a longitudinal analysis of 288 adults receiving durable continuous‐flow LVADs from January 2010 to December 2017 at a single center. A joint model was constructed to evaluate change in eGFR over 2 years, the prespecified primary outcome, adjusted for the competing risks of death and heart transplantation. Median baseline eGFR was 60 mL/min per 1.73 m
2
(interquartile range 42–78). At 2 years, 74 patients died and 104 received a heart transplant. In unadjusted analysis, LVAD recipients had a modest initial increase in eGFR of ≈2 mL/min per 1.73 m
2
within the first 6 months after implantation, followed by a decrease in eGFR below baseline values at 1 and 2 years. Men experienced an eGFR decline of 5 to 10 mL/min per 1.73 m
2
over the first year which then stabilized, while women had an ≈5 mL/min per 1.73 m
2
increase in eGFR within the first 6 months followed by decline towards baseline eGFR levels (interaction
P
=0.005).

Conclusions

Estimated GFR remains relatively stable in most patients following LVAD implantation. Larger studies are needed to investigate sex‐based differences in eGFR and to evaluate eGFR trajectory and mortality in LVAD recipients with lower eGFR.
MicroRNA-210 Downregulates TET2 (Ten-Eleven Translocation Methylcytosine Dioxygenase 2) and Contributes to Neuroinflammation in Ischemic Stroke of Adult Mice
Authors: Li Yong , Song Rui , Shen Guofang , Huang Lei , Xiao DaLiao , Ma Qingyi , Zhang Lubo
Published: February 2023

Background:

Stroke is a leading cause of morbidity and mortality worldwide. Neuroinflammation plays a key role in acute brain injury of ischemic stroke. MicroRNA-210 (miR210) is the master hypoxamir and regulates microglial activation and inflammation in a variety of diseases. In this study, we uncovered the mechanism of miR210 in orchestrating ischemic stroke–induced neuroinflammation through repression of TET2 (ten-eleven translocation methylcytosine dioxygenase 2) in the adult mouse brain.

Methods:

Ischemic stroke was induced in adult WT (wild type) or miR210 KO (miR210 deficient) mice by transient intraluminal middle cerebral artery occlusion. Injection of TET2 silencing RNA or miR210 complementary locked nucleic acid oligonucleotides, or miR210 KO mice were used to validate miR210-TET2 axis and its role in ischemic brain injury. Furthermore, the effect of TET2 overexpression on miR210-stimulated proinflammatory cytokines was examined in BV2 microglia. Post assays included magnetic resonance imaging scan for brain infarct size; neurobehavioral tests, reverse transcription-quantitative polymerase chain reaction, and Western blot for miR210; and TET2 levels, flow cytometry, and ELISA for neuroinflammation in the brain after stroke or microglia in vitro.

Results:

miR210 injection significantly reduced TET2 protein abundance in the brain, while miR210 complementary locked nucleic acid oligonucleotides or miR210 KO preserved TET2 regardless of ischemic brain injury. TET2 knockdown reversed the protective effects of miR210 inhibition or miR210 KO on ischemic stroke–induced brain infarct size and neurobehavioral deficits. Moreover, flow cytometry and ELISA assays showed that TET2 knockdown also significantly dampened the anti-inflammatory effect of miR210 inhibition on microglial activation and IL (interleukin)-6 release after stroke. In addition, overexpression of TET2 in BV2 microglia counteracted miR210-induced increase in cytokines.

Conclusions:

miR210 inhibition reduced ischemic stroke–induced neuroinflammatory response via repression of TET2 in the adult mouse brain, suggesting that miR210 is a potential treatment target for acute brain injury after ischemic stroke.
Time Courses of Attended and Ignored Object Representations
Authors: Noah Sean , Meyyappan Sreenivasan , Ding Mingzhou , Mangun George R.
Published: February 2023

Selective attention prioritizes information that is relevant to behavioral goals. Previous studies have shown that attended visual information is processed and represented more efficiently, but distracting visual information is not fully suppressed, and may also continue to be represented in the brain. In natural vision, to-be-attended and to-be-ignored objects may be present simultaneously in the scene. Understanding precisely how each is represented in the visual system, and how these neural representations evolve over time, remains a key goal in cognitive neuroscience. In this study, we recorded EEG while participants performed a cued object-based attention task that involved attending to target objects and ignoring simultaneously presented and spatially overlapping distractor objects. We performed support vector machine classification on the stimulus-evoked EEG data to separately track the temporal dynamics of target and distractor representations. We found that (1) both target and distractor objects were decodable during the early phase of object processing (∼100 msec to ∼200 msec after target onset), and (2) the representations of both objects were sustained over time, remaining decodable above chance until ∼1000-msec latency. However, (3) the distractor object information faded significantly beginning after about 300-msec latency. These findings provide information about the fate of attended and ignored visual information in complex scene perception.

Defining Value in Sustainable Business Models
Authors: Neesham Cristina , Dembek Krzysztof , Benkert Julia
Published: February 2023

Although the concept of value is central to sustainable business models (SBMs), the field has struggled to clarify what value is. SBM research accounts for multiple forms of value directed at multiple stakeholders. We argue that this diversity challenge should be addressed not by seeking a field-unifying definition of value but by developing methodological guidelines for a field-specific approach to defining value in SBM contexts. Based on Aristotelian logic and philosophical phenomenology of value, we develop an analytical framework that can be used for generating good definitions of value. We use this framework to explore approaches to value in extant SBM literature, highlight problematic patterns in applications of this concept, and suggest ways to avoid these patterns. The result is a guide to assist SBM researchers in exploring and defining value, and in applying their definitions consistently in theory building efforts.
Toward A Discourse on the Threat of Performative Wokeness to Justice Agendas in Education
Authors: Marshall Patricia L. , Wilson Jonee
Published: February 2023

Among the most urgent matters in contemporary education discourses are those that delve into the justice issues related to diversity, equity, and inclusion. Colleges of Education are critical sites for such discourse. In particular, the teaching methods course is where candidates are to acquire tools to take up such issues. Success of justice agendas depends on the receptivity of individuals to engage in ways that are critical, substantive, and above all authentic. But what challenges present if receptivity is feigned? In this paper, we describe encounters with the phenomenon of performative wokeness and how it threatens justice agendas.
Assessing the performance gap of two dynamic thermal modelling software tools when comparing with real-time data in relation to thermal loss
Authors: Salehi Bahareh , Andrews Deborah , Chaer Issa , Gillich Aaron , Newton Elizabeth J
Published: February 2023

Managing thermal loss is a key topic that needs further investigation as it has a direct link to reducing the energy load in buildings. One of these thermal loss management methods can be the use of shading devices. Dynamic thermal models normally used at the early stages of the building design can play an important role in the decision-making process regarding the use of shading devices. This paper presents the results of a real-world study assessing the potential of using a sealed cellular blind as a passive energy conservation method, where the real-world results are compared with the simulated results generated with environmental design solutions limited thermal analysis software (EDSL Tas) and integrated environmental solutions virtual environment (IES VE). During the real-world study, a positive impact of having blinds was seen whereby the window surface temperature increased and office heating energy consumption was lowered. Both software tools were able to predict a similar trend of results for the window surface temperature in with and without blind scenarios whereas for energy consumption although in the presence of a blind a consistent correlation is seen between measured and calculated values but not without a blind. This can be attributed to the inability of the software tools in demonstrating the effect of infiltration in the absence of a blind or shading device i.e., a clear window scenario.

The performance gap analysis regarding thermal loss between dynamic thermal models and real-world settings within buildings can enhance the predictability of the building energy software tools used by designers. Early design inputs within buildings can prevent costly building re-work to improve the building’s energy performance. This can also improve the understanding within the building industry of the importance of reducing thermal loss through the use of shading devices and ensuring the software tools used to model these devices are as close to real-world settings as possible.

Published: February 2023

This report describes a woman with a rare primary squamous cell carcinoma of the ovary accompanied by transition of a mucinous borderline ovarian tumor. A woman in her late 40s was referred for abdominal discomfort, which worsened during defecation. Pelvic magnetic resonance imaging showed a multiloculated cystic lesion in the left adnexa measuring approximately 7.5 × 9.5 × 7.0 cm. An intraoperatively obtained frozen biopsy sample of the mass in the left ovary was positive for malignancy, resulting in a surgical staging operation. The tumor was composed of squamous cell carcinoma and mucinous borderline tumor. There was no evidence of capsular invasion or invasion of other internal organs, including pelvic and para-aortic lymph nodes (0/41). Immunohistochemistry showed that the tumor was diffusely positive for cytokeratin 7, cytokeratin 20, Ki-67, and P40 but negative for P16. After a debulking operation, the patient has been monitored regularly without adjuvant therapy owing to final surgical staging of the tumor as stage IA.

Background:

There are limited studies designed by matching related factors to compare clinical outcomes and return to sport (RTS) between patients undergoing revision anterior cruciate ligament reconstruction (R-ACLR) and primary ACLR (P-ACLR).

Purpose:

(1) To compare the outcomes between R-ACLR and P-ACLR in a matched-pair analysis with 3- to 5-year follow-up and (2) to evaluate patient-reported factors for not returning to preinjury-level sport.

Study Design:

Cohort study; Level of evidence, 4.

Methods:

Patients who underwent R-ACLR between September 2016 and November 2018 were propensity matched by age, sex, body mass index, passive anterior tibial subluxation, and generalized hypermobility in a 1:1 ratio to patients who underwent P-ACLR during the same period. By combining in person follow-up at 2 years postoperatively and telemedicine interview at the final follow-up (January 2022), knee stability and clinical scores were compared, including International Knee Documentation Committee (IKDC), Lysholm, and Tegner. Status of RTS was requested, specifically whether the patient returned to preinjury level of sport. Patient-reported reasons for not returning were analyzed.

Results:

There were 63 matched pairs in the present study. Knee stability was similar in terms of KT-2000 arthrometer, Lachman test, and pivot-shift test results between the groups at 2 years of follow-up. At the final follow-up, no significant difference was found between groups for postoperative clinical scores (IKDC, Tegner, and Lysholm) ( P > .05). There was a significant difference in total RTS: 53 (84.1%) in the P-ACLR cohort and 41 (65.1%) in the R-ACLR cohort ( P = .014). No significant difference was shown in terms of RTS at the same level: 35 (55.6%) in P-ACLR and 31 (49.2%) in R-ACLR ( P = .476). Significantly more patients showed fear of reinjury: 26 of 32 (81.3%) in the R-ACLR group as compared with 15 of 28 (53.5%) in the P-ACLR group ( P < .021).

Conclusion:

R-ACLR resulted in similar clinical scores (IKDC, Tegner, and Lysholm) but significantly lower RTS versus P-ACLR at 3 to 5 years of follow-up. Fear of reinjury was the most common factor that caused sport changes in patients with R-ACLR.

Background

Royal Canadian Mounted Police (RCMP) report diverse occupational stressors and repeated exposures to potentially psychologically traumatic events, which may increase the odds of screening positive for a mental disorder, and increase the risk of death by suicide. The current study was designed to provide prevalence information regarding suicidal behaviours (i.e., ideation, planning, attempts) and assess for sociodemographic differences among cadets at the start of the RCMP Cadet Training Program (CTP).

Method

Cadets ( n = 736, 74.0% male) were administered the structured Mini International Neuropsychiatric Interview by a mental health clinician or a supervised clinical psychologist trainee. The interview includes an assessment of past month suicidal ideation, planning, attempts and lifetime suicide attempts.

Results

Within 1 month of starting the CTP, a small percentage of cadets reported past month suicidal ideation (1.6%) and no cadets reported any suicidal planning (0%) or attempts (0%). Lifetime suicide attempts were reported by (1.5%) of cadets.

Conclusions

The current results provide the first information describing the prevalence of suicidal ideation, planning, and attempts among RCMP cadets starting the CTP. The estimates of suicidal behaviours appear lower than the general population and lower than reports from serving RCMP. Higher prevalence estimates of suicidal behaviours reported by serving RCMP, relative to lower estimates among cadets starting the CTP in the current study, may be related to age, cumulative experiences or protracted exposures to operational and organizational stressors, rather than insufficient screening of recruits.
Navigating Through Nutrition Labeling Effects: A Second-Order Meta-Analysis
Authors: Zlatevska Natalina , Barton Belinda , Dubelaar Chris , Hohberger Jan
Published: February 2023

Nutrition labeling interventions are designed to provide consumers with easily interpretable nutritional information at the point of purchase. Despite the widespread implementation of these interventions and numerous research studies, there is little consensus as to their effect on consumer behavior. To address this issue, a novel methodology of second-order meta-analysis was utilized to provide a comprehensive synthesis of prior research on nutrition labeling effects. The difference in effects across published first-order meta-analyses was investigated based on whether the aim of the intervention was to prevent the consumption of unhealthy food or promote the consumption of healthy food (prevention vs. promotion focus). The extent to which the aim of the intervention impacts other intervention and study characteristics in study outcomes was additionally examined. Analysis of 93 first-order meta-analysis effect sizes highlighted differences according to whether the aim of the intervention was to prevent the consumption of unhealthy food or promote the consumption of healthy food. Differences were identified in the size of nutrition label effects for various label types, label location, and study and sample characteristics. In addition to important public policy implications, this research contributes to the ongoing discussion on the merits and limitations of meta-analysis methodology.
Recent developments in green hydrogen–environmental sustainability nexus amidst energy efficiency, green finance, eco-innovation, and digitalization in top hydrogen-consuming economies

The present era is facing a dilemma relating to engaging the essentialities of energy resources to attain economic prosperity due to the ensuing environmental complications. Consequently, sectors such as transport, aviation, and refining industries are under the scrutiny of reducing their reliance on fossil fuels achievable with the promotion of hydrogen energy which is largely neglected in the environmental empirics. To this end, the environmental impacts of green hydrogen in the top seven hydrogen-consuming countries are assessed from 1995 to 2019. Moreover, the roles of green finance, environmental-related technologies, energy efficiency, and digitalization are considered in the model specified within the STIRPAT framework. Second generation estimators comprising cross-section autoregressive distributed lag, Common Correlated Effect Mean Group, Augmented Mean Group, and Method of Moment Quantile Regression are employed in evaluating the stated hypotheses. Feedbacks from the analysis uncovered that green hydrogen; green finance, environmental-related technologies, energy efficiencies, digitalization, and structural change promote environmental sustainability in the top seven hydrogen-consuming countries. Contrariwise, natural resource dependence and urbanization trigger CO2 emissions, thereby exacerbating environmental complications. Based on the findings, policy measures leading toward sustainable environment are suggested.
Validating a Work-Related Well-Being Model in Handloom Weavers
Authors: Singh Sushmita , Singh S. K.
Published: February 2023

The study investigated work-related well-being among handloom weavers of Varanasi. The various dimensions of work-related well-being were work engagement, job satisfaction and occupational stress. The work also focused on inter-dimensional relationship of various components of work-related well-being. A cross-sectional survey design with random sampling method was used, and 325 handloom weavers were part of the survey. Exploratory factor analysis and confirmatory factor analysis was used to explore and validate the measurement instrument for work-related well-being. Pearson product-moment correlation coefficients were used to investigate the relationships among various dimensions. The model was tested using structural equation modelling on AMOS 22 platform. The outcomes were suggestive of a three-factor model of work-related well-being which included work engagement, occupational stress and job satisfaction as the components. The findings suggested that job satisfaction positively characterizes work-related well-being followed by work engagement. Occupational stress negatively explains work-related well-being.
Does the Base Metal Futures Market of India Support the MDH? An Empirical Evidence
Authors: Samal Laxmidhar , Kumar Das Sudhansu
Published: February 2023

The study examines the mixture of distribution hypothesis (MDH) and the sequential information arrival hypotheses (SIH) in the base metal futures market of India. We use near-month futures daily trading data of price, volume and open interest for 7 years. It is downloaded from the official website of Multi Commodity Exchange (MCX), India. The study supports the MDH as it confirms the existence of a contemporaneous correlation between the return and change in volume of all base metal futures traded at MCX, India. The article exhibits no causality between the return and volume change of metal futures which supports the MDH and contradicts the SIH. This indicates a greater level of market efficiency. The study finds unidirectional causality between the return and daily change of open interest and bidirectional causality between the change in volume and change in open interest. This is found for all base metal futures and this aspect is left for in-depth analysis by the futures studies.
