To conveniently implement the online detection of grain moisture in combined harvesters and the address the influence of the no-load measurement baseline, thereby enhancing detection accuracy and measurement continuity, this study developed a differential grain moisture detection device. For its convenient installation and integration on combined harvesters, a single-pole plate measurement element with a 1.6 mm thick epoxy resin coated with a 2-ounce copper film was designed, and a grain moisture detection device was constructed based on the STM32F103 microprocessor (STMicroelectronics International NV, Geneva, Switzerland). To enhance the device’s interference resistance, a differential amplification measurement circuit integrated with high-frequency excitation was designed using a reference capacitance. To improve the resolution of the measurement circuit, Malab simulations were conducted at different excitation frequencies, ultimately selecting 30 kHz as the system’s excitation signal frequency. To validate the effectiveness of the measurement circuit, validity tests were performed on the constructed sensor, which showed that the sensor’s measurement voltage could effectively distinguish the moisture levels in grains, with a determination coefficient (R²) reaching 0.9978. To address the errors in moisture measurement caused by changes in grain temperature, an interaction experiment of the effect of moisture content and temperature on the measurement voltage was conducted using an integrated temperature sensor, resulting in the construction of a moisture content calculation model. Both the indoor static detection and field testing of the moisture detection device were conducted, indicating that the maximum average error in static measurements was 0.3%, with a maximum relative error of 0.47%, and the average relative error in field tests was ≤0.4%.

A turn from the “whither” to the “whence” of anarchism is at stake in Catherine Malabou’s interpretation of Latin American decolonial theory. This is a turn from a materialist philosophy that seeks to open the space of anarchism within the modern state toward one that discerns anarchism as already operative in the modern state given the social implications of colonial legacies. In tracing this turn, I propose a development of Malabou’s work insofar as I put her in dialogue with María Lugones, who is much closer to Malabou than the more canonical decolonial figures she actively engages, especially in view of anarchism as a form of social–political plasticity. Understanding Lugones’ critique of earlier iterations of decolonial theory helps make explicit an immanent anarchic resistance to domination as an explosive inhabitation of everyday loci of tension.

Catherine Malabou’s conception of plasticity as potentially having a creative or destructive form provides both philosophy and the neurosciences with a dynamic and generative concept for describing the workings and transformations of psychological, social, and material phenomena. Exploring the dynamism of Malabou’s plasticity, I question: how is plasticity, whether as a giving or receiving form, constituted to be so dynamic? Drawing somewhat from Heidegger’s account of change, I propose thinking of form as existing within a world of forces, to be a force, and be composed of force(s). The problem being, though somewhat presupposed and even alluded to in her elaborations of form and destructive plasticity, Malabou doesn’t conceptualize force nor advance it as a necessity for conceptualizing plasticity. Nevertheless, developing upon Christopher Watkin’s idea for engaging Malabou’s plasticity relationally within a broader ecology, we come to see how, whether ontically or ontologically, force(s) appear to be what makes plasticity dynamic. As a result, in order to address the figure of force as being integral to form, I argue that Malabou will need to somehow transfigure her conception of plasticity. Ultimately, in my estimation, such elaboration may lead to plasticity’s conceptual re-birth in the form of a mediating force. Full article

This article investigates the meaning of Merleau-Ponty’s concept of the flesh of the world. This concept brings a cosmological tone to existentialist phenomenology and challenges the grim and gnostic approach that prevails in Heidegger’s and Sartre’s works in particular. Is horror the key mood in ontology as argued by Malabou? This article contends that bright metaphors and magic realism are at least as fundamental, but under one condition: ontology must come to terms with what the author has coined as the “Chandos complex”, namely a form of ambivalence and oscillation between Gnosticism and holism that makes both positions fake and hollow. Dreaming of being one with the world and fantasizing an estrangement from nature work hand in hand and are equally staged. Merleau-Ponty’s philosophy occasionally falls prey to the Chandos complex, which makes his concept of the flesh of the world vulnerable to criticism. This article examines the claim put forward by Renaud Barbaras that “the flesh of the world” is a failed metaphor. It argues that this blissful metaphor is ontologically fundamental as soon as its intrinsic paradoxes are recognized and accepted: the Chandos complex then becomes the key to an ontology that recognizes the imaginary as an essential dimension of being. At stake is an essential link between ontology on the one hand and, on the other hand, metaphors as well as myth-building and narrative-building processes. Full article

Prostate cancer has one of the highest incidences of male malignant tumors worldwide. Its treatment involves the robotic implantation of radioactive seeds in the perineum, a safe and effective procedure for early, low-risk prostate cancer. In order to ensure precise positioning, the seed implantation needle is set at low terminal velocity. In this paper, the motion output position instability caused by the friction torque of the robot’s motor and rotating joint during low velocity motion was analyzed and studied. This paper also presents a compensation control method based on the LuGre friction model, which offers piecewise parameter identification with GA-PSO. First, based on an analysis of its structure and working principle, the friction torque model of the robotic system and the torque model of the driving motor are established, and the influence of friction torque on motion stability analyzed. Then, based on experimental data of the relationship between velocity and friction torque for no-friction compensation, the velocity point of the minimum torque of the rotating joint and the critical Stribeck velocity point were used for segmental parameter identification; cubic spline interpolation was used for segmental fitting. Furthermore, on the basis of the LuGre model identification method, parameter identification of the genetic algorithm-particle swarm optimization, and compensation control of the LuGre friction model, a control method is analysed and set forth. Malab2017a/Simulink simulation software was used to simulate and analyze the control method, and verify its feasibility. Finally, the cantilever prostate seed implantation robot system was tested to verify the effectiveness of the segmented identification method and the compensation control strategy. The results reveal that motion output position stability at low velocity meets the requirements of the cantilever prostate seed implantation robot, thus providing a vital reference for further research.

Amyloid is an insoluble fibrous protein and its mis-aggregation can lead to some diseases, such as Alzheimer’s disease and Creutzfeldt–Jakob’s disease. Therefore, the identification of amyloid is essential for the discovery and understanding of disease. We established a novel predictor called RFAmy based on random forest to identify amyloid, and it employed SVMProt 188-D feature extraction method based on protein composition and physicochemical properties and pse-in-one feature extraction method based on amino acid composition, autocorrelation pseudo acid composition, profile-based features and predicted structures features. In the ten-fold cross-validation test, RFAmy’s overall accuracy was 89.19% and F-measure was 0.891. Results were obtained by comparison experiments with other feature, classifiers, and existing methods. This shows the effectiveness of RFAmy in predicting amyloid protein. The RFAmy proposed in this paper can be accessed through the URL http://server.malab.cn/RFAmyloid/. Full article

This article addresses a significant gap in trauma theory and philosophy; namely, it develops a partial theory of the subject of intergenerational trauma. This is accomplished through a close examination of Catherine Malabou’s theory of the subject of trauma, as well as by contact with the research in epigenetics of Rachel Yehuda, and the research on intergenerational trauma among First Nations people in Canada conducted by Amy Bombay and colleagues. It presents original work that is responsive to recent advances in a variety of fields, including philosophy, psychology, social science, and biology. Full article

Although we live in a post-metaphysical age, there is a renewed interest in transcendence, especially at the intersection of philosophy, religion, and theology. There are several reasons for this: among others, the important link that the future (eschatology) has with the unknown or that which lies beyond (transcendence). In this article, this relation between eschatology and transcendence is explored by analysing different concepts of transcendence and their possible relations to the future. Jacques Derrida and Catharine Malabou’s concepts of the future are used to shed light on the link between eschatology and transcendence as “impossible”. Secondly, Jean-Luc Nancy’s concept of transimmanence is introduced, in an attempt to find such a possible link. A reconceptualisation of transcendence as transimmanence and a reconceptualisation of the future of eschatology as something “outside within”, facilitate a link between these terms, but the original or general meanings of these terms then become impossible. This outcome urges a rethinking of the meaning and role of transcendence, eschatology, and the future in our post-metaphysical age. Full article
