Magnetohydrodynamic-based Internal Cooling System for a Ceramic Cutting Tool: Concept Design, Numerical Study, and Experimental Validation
Authors: O’Hara John , Fang Fengzhou 
Published: August 2023

AbstractThe effective removal of the heat generated during mechanical cutting processes is crucial to enhancing tool life and producing workpieces with superior surface finish. The internal cooling systems used in cutting inserts employ a liquid water-based solvent as the primary medium to transport the excess thermal energy generated during the cutting process. The limitations of this approach are the low thermal conductivity of water and the need for a mechanical input to circulate the coolant around the inner chamber of the cutting tool. In this context, this paper proposes an alternative method in which liquid gallium is used as the coolant in combination with a magnetohydrodynamic (MHD) pump, which avoids the need for an external power source. Using computational fluid dynamics, we created a numerical model of an internal cooling system and then solved it under conditions in which a magnetic field was applied to the liquid metal. This was followed by a simulation study performed to evaluate the effectiveness of liquid gallium over liquid water. The results of experiments conducted under non-cooling and liquid gallium cooling conditions were analyzed and compared in terms of the tool wear rate. The results showed that after six machining cycles at a cutting speed Vc = 250 m min −1, the corner wear VBc rate was 75 µm with the coolant off and 48 µm with the MHD-based coolant on, representing a decrease of 36% in tool wear. At Vc = 900 m min−1, the corner wear VBc rate was 75 µm with the coolant off and 246 µm with the MHD-based coolant on, representing a decrease of 31% in tool wear. When external cooling using liquid water was added, the results showed at Vc = 250 m min−1, the difference between the tool wear rate reduction with the internal liquid gallium coolant relative to the external coolant was 29%. When the cutting speed was increased to Vc = 900 m min−1, the difference observed between the internal liquid gallium coolant relative to the external coolant was 16%. The study proves the feasibility of using liquid gallium as a coolant to effectively remove thermal energy through internally fabricated cooling channels in cutting inserts.

Published: August 2023

AbstractEfficient and economical wastewater treatment has presented itself as a global challenge. In this context, adsorption is one of the most effective methods to remove contaminants from wastewater. The present study evaluated the feasibility of chemically modified pine bark biochar’s nitrate adsorption ability. Pine bark biochar was modified with urea and sulfuric acid to remove nitrate from an aqueous solution. The physicochemical properties of the biochar samples, such as pH, pH at point of zero charges, surface atomic composition, surface morphology, and surface area, were evaluated. The equilibrium adsorption data were fitted to the Langmuir and Freundlich isotherm models. The kinetic data were fitted to different kinetic models (pseudo-first order, pseudo-second order, intraparticle diffusion, and Elovich). The adsorption data fitted well with the Langmuir and pseudo-first order models. The maximum nitrate adsorption capacity was found to be 1.548 mg g−1. Mass transfer studies were conducted to identify the rate-limiting step, values of the external mass transfer coefficient, and diffusion coefficient in the nitrate adsorption process by the modified biochar. The external mass transfer coefficients were in the range of 2.2 × 10–11–2.86 × 10–10 m s−1. The intraparticle diffusion coefficient ranged from 6.53 × 10–10 to 1.78 × 10–9 m2 s−1. The Biot number value less than 100 indicated that the adsorption was controlled by film diffusion. Interaction energies between nitrate ions and model biochar structures were calculated DFT-based quantum chemical software (Gaussian). The positive interaction energy values (2.3485–2.485 eV) suggested nitrate adsorption on model biochar structures was thermodynamically not feasible.

Idecomp: imbalance-aware decomposition for class-decomposed classification using conditional GANs
Authors: Buczek Patryk , Zidan Usama , Gaber Mohamed Medhat , Abdelsamea Mohammed M. 
Published: August 2023

AbstractMedical image classification tasks frequently encounter challenges associated with class imbalance, resulting in biased model training and suboptimal classification performance. To address this issue, the combination of class decomposition and transfer learning has proven to be effective in classifying imbalanced medical imaging datasets. Nevertheless, in order to further augment the performance gains achieved through the utilisation of class decomposition within deep learning frameworks, we propose a novel model coined imbalance-Aware Decomposition for Class-Decomposed Classification (iDeComp) model. By incorporating a conditional Generative Adversarial Network (GAN) model, iDeComp is capable of generating additional samples specifically tailored to underrepresented decomposed subclasses. This paper investigates the application of iDeComp using two different medical imaging datasets. iDeComp selects underrepresented samples from the training set of the sublevel classes within each dataset, which are then employed to train separate conditional Deep Convolutional GAN (DCGAN) models and verification models. The conditional DCGAN model is responsible for generating additional samples, while the verification model critically evaluates the appropriateness of the synthesised images. Subsequently, the resulting augmented samples are utilized to train the classification model. To assess the effectiveness of iDeComp, we employ various evaluation metrics including accuracy, precision, recall, and F1 score. The results obtained from our experiments clearly indicate that iDeComp outperforms existing approaches in terms of classifying both imbalanced datasets.

Explanation and the Right to Explanation
Authors: TAYLOR ELANOR 
Published: August 2023

AbstractIn response to widespread use of automated decision-making technology, some have considered a right to explanation. In this article, I draw on insights from philosophical work on explanation to present a series of challenges to this idea, showing that the normative motivations for access to such explanations ask for something difficult, if not impossible, to extract from automated systems. I consider an alternative, outcomes-focused approach to the normative evaluation of automated decision making and recommend it as a way to pursue the goods originally associated with explainability.

Published: August 2023

ABSTRACT:Parkinson’s disease(PD) lacks a biomarker for disease progression. To analyze how cerebrospinal fluid (CSF), glucosylceramide (GlcCer), sphingomyelin (SM), or serum neurofilament light chain (NfL) associate with progression of PD in a retrospective cohort, we used linear mixed-model regressions between baseline biomarkers and change in dopamine transporter brain-imaging (DaTscan©), Montreal cognitive assesment (MoCA), or global composite outcome (GCO) score. In 191 PD patients, biomarkers were not associated with DaTscan or MoCA change over 2.1 years. Higher baseline GlcCer/SM ratio and serum-NfL nonsignificantly associated with increase in GCO score. Results do not support a role for CSF-sphingolipid/serum-NfL to predict cognitive and DaTscan progression in early-PD. Potential prediction of global clinical change warrants further study.
The Impact of Pollutants and Deforestation on the Spread of Monkeypox: An Unintended Consequence of Progress
Authors: Singh Ajeet , Shaikh Bisma 
Published: August 2023

Abstract
Monkeypox (MPX) is a rare zoonotic illness, like smallpox, caused by the monkeypox virus, which is a member of the Orthopoxvirus genus of the Chordopoxvirinae subfamily that falls under the classification of the Poxviridae family. MPX is clinically characterized by a wide variety of symptoms and signs, including fever, sore throat, headache, myalgia, lymphadenopathy, and rashes. As the world is undergoing progressive industrialization over time, there is a corresponding increase in environmental pollutants and deforestation. Previous studies have found a correlation between exposure to environmental contaminants and the incidence of MPX. Additionally, it has been hypothesized that deforestation may also have played a role in the disease’s resurgence or in its ability to spread. Habitat loss and ecological instability brought on by environmental contaminants and deforestation may increase human-infected animal interaction and hasten the spread. The likely connection should be known by health authorities and doctors, as well as government officials, to help fund further investigations and craft strategies to combat the risk of an increasing prevalence of MPX in the world, especially in densely populated underdeveloped regions of Asia and Africa, where containment of MPX poses greater challenges. In this article, we have provided an important real-world perspective and suggested future recommendations to halt the further spread of MPX to new places.
Need for living wages in India: Case studies of agricultural workers in rural Madhya Pradesh

Published: August 2023

AbstractThe present study discusses the current wage situation in India and the need for living wages as workers and employees grapple with the cost of living crisis. A case study of two districts of Madhya Pradesh (MP) state is presented to demonstrate how the living wage benchmarks based on the Anker Methodology compare with existing minimum wage fixations and other development indicators. The living wage benchmarking is based on field surveys conducted in Ratlam and Chhindwara districts in October–December 2021, and a rigorous analysis of nationally representative consumption and expenditure surveys conducted by the National Sample Survey Organisation and the Centre for Monitoring Indian Economy. Our living wage estimates are 1.8 times the minimum wages for agricultural labourers and 43% more than those earned by non-agricultural unskilled labourers. Moreover, the actual wages reported are less than half of the estimated living wages, indicating that the current incomes and wages for workers and farmers of rural MP are far from adequate to lead a decent life.
Competition among the two-plasmon decay of backscattered light, filamentation of the electron-plasma wave and side stimulated Raman scattering

Abstract
Competition among the two-plasmon decay (TPD) of backscattered light of stimulated Raman scattering (SRS), filamentation of the electron-plasma wave (EPW) and forward side SRS is investigated by two-dimensional particle-in-cell simulations. Our previous work [K. Q. Pan et al., Nucl. Fusion 58, 096035 (2018)] showed that in a plasma with the density near 1/10 of the critical density, the backscattered light would excite the TPD, which results in suppression of the backward SRS. However, this work further shows that when the laser intensity is so high (

$>{10}^{16}$

W/cm2) that the backward SRS cannot be totally suppressed, filamentation of the EPW and forward side SRS will be excited. Then the TPD of the backscattered light only occurs in the early stage and is suppressed in the latter stage. Electron distribution functions further show that trapped-particle-modulation instability should be responsible for filamentation of the EPW. This research can promote the understanding of hot-electron generation and SRS saturation in inertial confinement fusion experiments.

Published: August 2023

AbstractDifferences in blood concentration of sex hormones in the follicular (FP) and luteal (LP) phases may influence energy metabolism in women. We compared fasting energy metabolism and sweet taste preference on a representative day of the FP and LP in twenty healthy women (25·3 (sd 5·1) years, BMI: 22·2 (sd 2·2) kg/m2) with regular self-reported menses and without the use of hormonal contraceptives. From the self-reported duration of the three prior menstrual cycles, the predicted FP and LP visits were scheduled for days 5–12 and 20–25 after menses, respectively. The order of the FP and LP visits was randomly assigned. On each visit, RMR and RQ by indirect calorimetry, sweet taste preference by the Monell two-series forced-choice tracking procedure, serum fibroblast growth factor 21 by a commercial ELISA (FGF21, a liver-derived protein with action in energy balance, fuel oxidation and sugar preference) and dietary food intake by a 24-h dietary recall were determined. Serum progesterone and oestradiol concentrations displayed the expected differences between phases. RMR was lower in the FP v. LP (5042 (sd 460) v. 5197 (sd 490) kJ/d, respectively; P = 0·04; Cohen effect size, drm = 0·33), while RQ showed borderline significant higher values (0·84 (sd 0·05) v. 0·81 (sd 0·05), respectively; P = 0·07; drm = 0·62). Also, in the FP v. LP, sweet taste preference was lower (12 (sd 8) v. 16 (sd 9) %; P = 0·04; drm = 0·47) concomitant with higher serum FGF21 concentration (294 (sd 164) v. 197 (sd 104) pg/ml; P < 0·01; drm = 0·66). The menstrual cycle is associated with changes in energy expenditure, sweet taste preference and oxidative fuel partitioning.

AbstractBackgroundClinical implementation of risk calculator models in the clinical high-risk for psychosis (CHR-P) population has been hindered by heterogeneous risk distributions across study cohorts which could be attributed to pre-ascertainment illness progression. To examine this, we tested whether the duration of attenuated psychotic symptom (APS) worsening prior to baseline moderated performance of the North American prodrome longitudinal study 2 (NAPLS2) risk calculator. We also examined whether rates of cortical thinning, another marker of illness progression, bolstered clinical prediction models.MethodsParticipants from both the NAPLS2 and NAPLS3 samples were classified as either ‘long’ or ‘short’ symptom duration based on time since APS increase prior to baseline. The NAPLS2 risk calculator model was applied to each of these groups. In a subset of NAPLS3 participants who completed follow-up magnetic resonance imaging scans, change in cortical thickness was combined with the individual risk score to predict conversion to psychosis.ResultsThe risk calculator models achieved similar performance across the combined NAPLS2/NAPLS3 sample [area under the curve (AUC) = 0.69], the long duration group (AUC = 0.71), and the short duration group (AUC = 0.71). The shorter duration group was younger and had higher baseline APS than the longer duration group. The addition of cortical thinning improved the prediction of conversion significantly for the short duration group (AUC = 0.84), with a moderate improvement in prediction for the longer duration group (AUC = 0.78).ConclusionsThese results suggest that early illness progression differs among CHR-P patients, is detectable with both clinical and neuroimaging measures, and could play an essential role in the prediction of clinical outcomes.
Embracing the mystery: David Hume's playful religion of wonder
Authors: Lingier Hannah 
Published: August 2023

AbstractIn this article I show how David Hume's works provide the ingredients for a conception of religiosity understood as a feeling of wonder concerning nature or existence, accompanied by a playful attitude regarding the imaginative shapes that can be given to this emotion. Hume serves as an inspiration rather than an object of study: I respect the spirit and values of his work, while going beyond his own explicit points. My reading accounts for Hume's aversion to traditional religions (‘superstition’), and for his acknowledgement of the universal attraction of the idea of invisible intelligent power and his own fascination with it. I argue first that superstition is a natural reaction to existential uncertainty. Second, I argue that uncertainty fuels activity, creativity and morality, and thus may be left untended. Though it always involves a measure of pain, too, human happiness is found in challenge and activity. Traditional monotheist religions respond to this need by generating experiences of wonder, thus, however, stimulating passive devotion and dogmatism. Opposing this, the suggestion of Hume's works is to respect the mystery of nature rather than shrouding it in unfounded convictions. The fictional character Philo illustrates how the longing for an answer by is itself can already be a profoundly religious feeling. Hume's descriptions of ancient polytheism and Philo show how this can be accompanied by a playful, imaginative interaction with the world.
“Workers do not liberate themselves other than with their own hands”—The Political Experience of Workers' Committees in the Industrial District of Beirut (1970–1975)
Authors: Tufaro Rossana 
Published: August 2023

AbstractFrom the end of the 1960s until the outbreak of the Civil War (1975), Lebanon experienced a phase of relatively sustained industrial expansion. Albeit the “boom” did not modify significantly Lebanon's tertiarized economic structure, it was anyway sufficient to create the structural conditions for the emergence of a new militant working-class able to become one of the most relevant contentious actors of its time. This new working class was made primarily of very young and recently urbanized unemployed of rural origin, brutally injected in a crude and hyper-exploitative productive cycle where formal labor unions were, for the most part, absent or scarcely effective. The input for their grassroots, transgressive organization into factory-based Workers’ Committees came from the Organization for Communist Action in Lebanon (OACL), i.e. the most important force of the so-called Lebanese New Left, within the framework of a broader process of militant penetration of the “revolutionary classes” produced by the contradictions of Lebanese capitalism. This created the precondition for the Committees to affirm themselves not only as the radical avant-garde of the Lebanese labor movement but also as an integral part of a broader process of contestation of the existing status quo by the subaltern groups emerged from - or activated by - the structural and cultural changes that the country was experiencing. By retrieving the forgotten history of the Workers’ Committees, the article wants to examine the forms and the trajectories whereby such a new working class became an integral part of this process. In particular, by adopting a Gramscian methodology, the article will first expose the structural changes in the Lebanese industrial sector in the examined period and their labor implications. Then, it will focus on the dynamics which superseded the Committees' birth and affirmation, reserving particular attention to the role played by the OACL. Finally, it will conclude by examining the impact of their agency on the political developments that the country was experiencing. The paper contends that the emergence and the affirmation of counter-hegemonical and transformative working-class activism on the eve of the Civil War, along with representing a direct by-product of structural stresses and constraints, was significantly debtor also of the new ideological and militant infrastructures that the emergence of an Arab New Left had contributed to popularize and deploy. The paper wants also to intervene in the historiographical debate on the Lebanese Civil War, stressing the importance of both subaltern actors and class phenomena in its outbreak, which have generally been widely disregarded by the dominant understandings of the conflict.
When resilience is not enough: Imagining novel approaches to supporting Black youth navigating racism

Published: August 2023

AbstractThe narrative surrounding the impact racism has had on the well-being of Black youth has shifted across sociocultural and historical context. Early discourse around these topics were problem-saturated, focusing on deficits “within” Black youth. Over time, an important narrative shift occurred: greater attention was paid to the inherent assets of Black youth, their families, and communities, including how racial-ethnic protective factors such as racial socialization afforded them resilience. What resulted was decades of research seeking to understand the mechanisms that allow Black youth to bounce back in spite of racism-related adversity. Notwithstanding the viable practice and policy implications that have emerged from such inquiry, at what point does our focus on the resilience of Black youth – whether individual or multisystemic – fall short? It is with this question in mind that this paper challenges those committed to the optimal development of Black youth to consider yet another narrative shift: one that stands upon the legacy of cultural ecological frameworks and the seminal models underlying resilience research, and calls us toward not supporting Black youth’s adaptation to racism, but toward collective efforts to transform our approach, pushing back against the perniciousness of racism.
