On classical gravitational corrections to the functional Schrödinger equation
Authors: Reginatto M 
Published: November 2024

Abstract
A full theory of quantum gravity is not yet available, and an approximation in which spacetime remains classical while matter is described by quantum fields is often physically and computationally appropriate. It is therefore of interest to investigate hybrid systems which describe the interaction of classical gravity with quantum matter. Such systems may provide valuable clues relevant to the search of a quantum theory of gravity. Furthermore, one should also consider the possibility that the gravitational field may not be quantum in nature; in that case, it would become necessary to search for a consistent hybrid description.
It is known that the Wheeler-De Witt equation with coupling to quantum fields results in quantum gravitational corrections to the functional Schrödinger equation. A similar result can be obtained for some hybrid models where a classical gravitational field interacts with quantum matter fields. I use the approach of ensembles on configuration space to look at a hybrid model where matter is in the form of a quantized scalar field and determine the corresponding classical gravitational corrections to the functional Schrödinger equation.

Published: November 2024

Abstract
Composites have been increasingly used when weight is an essential factor to be considered. Composite structures have been proposed in deep sea field as competitive replacement of traditional steel structures. So, it is very important to evaluate the mechanical performance of composite structures under high external pressure in order to avoid potential failure or over conservative designs. In this study, solution is proposed for multi-layered composite cylinder based on the classical laminated-plate theory and detailed stress-strain responses are investigated by using the proposed analytical method. It was found that the cylinder is more sensitive to external pressure than internal pressure and the difference between axial stresses is up to 8.2%. In addition, the stacking sequence has great influence on stress distribution through the thickness direction and the sequence of [45/0] may change the stress from tensile to compressive for two adjacent layers. Finally, the difference between hoop stresses at the internal and external surfaces is not affected by the ratio of radius to thickness.

Published: November 2024

Abstract
In robot-driven composite manufacturing, managing the temperature field is crucial for determining the strength of the molding. This paper presents a process simulation analysis of the temperature field during the robot placement of thermoplastic composite materials on curved surfaces. The paper establishes an optimized temperature field model for the lay-up process on curved surfaces. Innovatively considering the influence of different plys on the heating temperature, this model can calculate the optimal heating temperature parameters for various ply layers. A two-dimensional heat transfer model is created using APDL command flow in ANSYS, and the mesh is partitioned. Transient thermal analysis is then conducted utilizing the “birth and death” element technique. Analyzing the effects of mold temperature, robot placement speed, and heating temperature on the temperature field of the first ply helps to understand their impact on multiple plys in the placement of curved surfaces. This analysis provides insights into how these factors influence the overall process.
Exploring the mechanisms of thermal insulation and heat conduction properties of composite materials based on simulation models
Authors: Cheng Chuanao , Dong Chengyuan , Lou Xu 
Published: November 2024

Abstract
The thermal conductivity of the composite material was simulated using DIGIMAT-FE software to predict the range of thermal conductivity values, which can reduce the amount of laboratory experimentation and help material developers accurately predict the thermal insulation properties of the material. Additionally, an insulating composite material was prepared by incorporating hollow glass microspheres (HGM) as a single thermal insulation filler into a silicone rubber matrix, and the thermal conductivity of this insulating composite was tested. The heat flux density and thermal conductivity of the composite material with the addition of HGM were described through computational simulation. The simulated thermal conductivity values were compared with laboratory test data to verify the agreement between the calculated and experimental values. Combining experiments with numerical simulations using DIGIMAT software, we conducted simulations of the thermal conductivity of composite materials to explore the mechanisms of thermal insulation. When heat transfers through composite insulation materials, the heat flux density in the thermal insulation phase is significantly lower than that in the matrix. The calculated and experimental values of HGM/LSR and HSM/LSR composites are in good agreement. The study on the impact of hollow glass microspheres (HGM) as a single thermal insulation phase on the performance of the silicone rubber matrix reveals that HGM microspheres can significantly reduce the thermal conductivity of the insulation material and enhance its thermal insulation performance.

Published: November 2024

Abstract
Recently, infrared scattering has caught people’s interest because of its stealth capabilities, heat insulation properties, polarization control, and other factors. This study specifically explores Mie scattering in the infrared spectrum, which is a well-established theory describing how light is absorbed and scattered by particles. We will analyze the periodic structure of nanoparticles made from ZnS, calculating their reflectance, transmission, and far-field scattering characteristics. Lastly, we will present scattering effect of ZnS/SEBS coating sprayed onto metal, illustrating how multiple-particle Mie scattering can achieve stealth capabilities.

Abstract
The Transition Radiation Detector (TRD) is a critical component of the High Energy Cosmic Radiation Detection (HERD) experiment, calibrating the electromagnetic calorimeter at the TeV energy range and observing X-rays in the all-sky survey. To support HERD-TRD test, a comprehensive ground detection system featuring a data acquisition (DAQ) board and host computer software was designed and implemented. The DAQ system manages data from six front-end electronics (FEE), totaling 768 detector channels, using an LVDS interface for high-speed scientific data transfer and an RS422 interface for command and telemetry. Gigabit Ethernet and mini USB enable real-time communication with the host computer. Host computer software developed on the QT platform efficiently manages data acquisition, storage, and display. The DAQ board offers a compact circuit design and complete functionality, and the host software provides an intuitive user interface. The DAQ board and host computer software have been tested to meet the design requirements. Performance tests show that the system realizes a stable data transfer rate of 360 Mbps over Gigabit Ethernet and 55 Mbps from the FEE to the DAQ board. The system has minimal noise and runs continuously for a week without data loss. In addition, a joint test with TRD using the 55Fe radioactive source was performed, and the particle signal was correctly acquired.

Optical gating characteristic time of measurement with 20 picoseconds resolution for an ultrafast image intensifier
Authors: Zhang Mei , Peng Bo-Dong , Guo Quan , Li Yang 
Published: November 2024

Abstract
In order to study the optical gating time characteristic of
an ultra-fast gated image intensifier, a precision measuring system
with 20 ps (picoseconds) trigger jitter is established. The
sequential gate images of the image intensifier with a time interval
of 20 ps are obtained at 0.125 ns ∼2 ns (nanoseconds) gating
electrical pulse modes. These images show that the intensifier has
the familiar normal “iris” turn-on and abnormal “iris” turn-off
behavior. The turn- on time is about 130 ps and the turn-off time
is about 170 ps. In 1 ns and 2 ns gating modes, the fully-on time
of optical gating almost is equal to the width of the electrical
gating pulse, In 0.5 ns, 0.25 ns and 0.125 ns modes, the fully-on
time is less than the width of the electrical gating pulse,
especially in the 0.125 ns gating mode, and the image in fully-on
phase is not observed. The width at 90% of the peak of the optical
gating time response curve may better characterize the fully-on time
of optical gating.

Published: November 2024

Abstract
The exploration of adaptive robotic systems capable of performing complex tasks in unstructured environments, such as underwater salvage operations, presents a significant challenge. Traditional rigid grippers often struggle with adaptability, whereas bioinspired soft grippers offer enhanced flexibility and adaptability to varied object shapes. In this study, we present a novel bioinspired soft robotic gripper integrated with a shape memory alloy (SMA) actuated suction cup, inspired by the versatile grasping strategies of octopus arms and suckers. Our design leverages a tendon-driven composite arm, enabling precise bending and adaptive grasping, combined with SMA technology to create a compact, efficient suction mechanism. We develop comprehensive kinematic and static models to predict the interaction between arm bending deflection and suction force, thereby optimizing the gripper’s performance. Experimental validation demonstrates the efficacy of our integrated design, highlighting its potential for advanced manipulation tasks in challenging environments. This work provides a new perspective on the integration of bioinspired design principles with smart materials, paving the way for future innovations in adaptive robotic systems.
Effects of maximum thickness position on hydrodynamic performance for fish-like swimmers
Authors: Xiong Zhongying , Han Tao , Xia Huan 
Published: November 2024

Abstract
When designing the internals of robotic fish, variations in the internal arrangements of power and control systems cause differences in external morphological structures, particularly the positions of maximum thickness. These differences considerably affect swimming performance. This study examines the impact of the topological structure of self-propelled fish-like swimmers on hydrodynamic performance using fluid–structure interaction techniques. Fish-like swimmers with maximum thickness closest to the head exhibit optimal swimming performance, characterized by modest energy consumption for fast-response acceleration during the starting phase and higher swimming velocity for high-speed travel during steady swimming. As the maximum thickness moves toward the middle, acceleration performance significantly weakens and swimming speed decreases, although maximum energy consumption is relatively reduced. This study will provide a notable reference for the morphological design of underwater robotic fish.
Terrestrial moisture sources dominate summer precipitation fluctuations in Northwest China

Published: November 2024

Abstract
Northwest China (NWC), is characterized by its arid and semi-arid environment, and exhibits high sensitivity to precipitation variations. Recent research indicates a wetting tendency over NWC, yet quantifying its moisture source remains challenging. Here, employing a 40 year simulation with Community Atmosphere Model version 5.1 (CAM5.1) coupled to an atmospheric water tracer algorithm, we ascertain that the dominant source of summer moisture over NWC are from terrestrial sources (82% of vapor and 77% of precipitation), i.e. from local evaporation, North Asia (NA), Europe (EUP), the southern Tibetan Plateau (STP), and southeastern China (SEC), rather than oceanic sources. Favorable synoptic patterns over NWC enhance the precipitation-conversion efficiency from the southeasterly airflow transport (STP and SEC) compared to northwesterly airflow (NA and EUP). We also find that the fluctuations in precipitation over NWC, manifesting as alternating dry and wet summers, are primarily driven by increased moisture contributions from direct inputs from NA and re-evaporation transport from STP. Our study indicates that moisture variability in inland is predominantly driven by nearby terrestrial sources and underscores the complex mechanisms of terrestrial moisture transport.
Eventually entanglement breaking divisible quantum dynamics
Authors: Szczygielski Krzysztof , Chruściński Dariusz 
Published: November 2024

Abstract
It is shown that a large class of quantum dynamical maps on complex matrix algebras governed by time-local Master Equations tend to become entanglement breaking in the course of time. Such situation seems to be generic for quantum evolution and in particular, completely positive dynamical semigroups with a unique faithful stationary state enjoy this property. Inspired by this observation, we propose a new concept of eventually entanglement breaking divisible (eEB-divisible) dynamics. A dynamical map is eEB-divisible if any propagator becomes entanglement breaking in finite time. It turns out that eEB-divisibility is quite general and holds for a large class of quantum evolutions.
Secularism and Its Cross-Pressures
Authors: John Aruthuckal Varughese 
Published: November 2024

Abstract
Chapter 2 argues that the condition of secularity in India entails specific cross-pressures between the community and the individual that lead to a distinct form of disenchantment among India’s upper castes. For this group, the advent of secularism entails a loss of the sacred, which is manifested in the Indian Constitution’s effect on traditional purity laws. By upholding individual rights, the Constitution has dismantled the walls that separated social groups, meaning the pure can no longer remain pure. Secular doctrine, via the Constitution and its ‘alien’ assumptions, fundamentally disrupts this well-oiled machine that has worked for several millennia. This disenchantment is aggravated by the ‘metro-secularists’, who, like their Western counterparts, are characterized by a commitment to individual autonomy and what Taylor calls ‘the ethics of authenticity’, a social and moral vision that many Indians view as antagonistic to both community and religion. This condition of secularity and the disenchantment it has caused is manifested in fundamental disagreements about the meaning of religious freedom.
Subversive Adaptations of Religious Converts
Authors: John Aruthuckal Varughese 
Published: November 2024

Abstract
This chapter explores how converts to Christianity tend to navigate a complex social landscape by occupying hybridized sites seeking to remain Hindu while following Christ. This strategy is especially visible in the Krista Bhakta (Christ followers) movement, the upper-caste groups who see a cultural continuity with the Hindu traditions. Using ‘hybridity’, a concept that Homi Bhabha popularized to capture the mixing of Eastern and Western cultures in postcolonial literature, the chapter explores how it can be applied in the religious sphere that adopts this subversive tool within political and cultural spheres.
Evolutionary significance of fixed chromosomal variants in South American populations of the leopard beetle Calligrapha polyspila (Coleoptera: Chrysomelinae)
Authors: Sandruss Zulema Gabriela , Estévez Daniela Yael , Steinberg Eliana Ruth , Papeschi Alba Graciela , Mudry Marta Dolores , Bressa María José 
Published: November 2024

Abstract
Chrysomelinae species have a striking ecological specialization due to their trophic selection on plants usually belonging to the same botanical family. Calligrapha (Chevrolat) (Coleoptera, Chrysomelidae) is a diverse genus that comprises about 80 species distributed in most of the American continent. Cytogenetic studies of Calligrapha refer to 18 species with a modal diploid chromosome number 2n = 23 = 22 + XO (male) and a meioformula n = 11 + XO (male). A population of C. polyspila (Germar) from República Oriental del Uruguay shows 2n = 24 = 22 + Xyp (n = 12 = 11 + X/yp, male), which is coincident with the karyotype currently considered as the ancestral one. We performed for the first time a detailed karyotype analysis in specimens of C. polyspila from Argentinean natural populations. We described the male karyotype and analyzed the meiotic behavior and frequency and distribution of chiasmata. We also examined the chromatin organization and constitution by determining the amount, composition, and distribution of constitutive heterochromatin and the number and location of nucleolus organizer regions. The presence of a novel 2n in C. polyspila from República Argentina allows proposing different trends of karyotype differentiation that may have occurred in the Argentinean and Uruguayan allopatric populations. Our results provide more information on the karyology of Chrysomelinae and contribute to discussing the evolutionary significance of the different cytological features and the fixed chromosomal variants observed in these South American populations of C. polyspila.
Bodymind Pains and Metabolic Conditions
Authors: Constantinesco Thomas 
Published: November 2024

Abstract
This essay identifies recent trends in the field of health humanities and reflects on their relevance for the study of nineteenth-century US literature, as well as on the contribution of Americanist literary criticism to health humanities enquiries. It first shows how health humanities scholarship invites us to think about body and mind as inextricable. It then demonstrates how a nondualist focus on the bodymind helps articulate the complexities of the experience of pain. As a wide array of nineteenth-century literary texts attests, bodyminds in pain ask to be understood through interconnected scales ranging from the singular to the collective, from the intimate to the social, from the microbiotic to the biopolitical. The final section thus considers the bodymind as a liminal site where these scalar dynamics intersect, turning to the way metabolic processes mediate conditions of health and illness while serving as an analytic for investigating wider biopolitical anxieties. Through the example of Henry James’s ambiguous valuation of “munching” at the turn of the twentieth century, when conditions such as obesity and diabetes emerged as alleged diseases of modernity, the essay concludes by pondering the entanglements between literature, foodways, and health as a fruitful avenue for further enquiry.

Abstract
Translational biology posits a strong bi-directional link between clinical phenotypes and a patient’s biological profile. By leveraging this bi-directional link, we can efficiently deconvolute pre-existing clinical information into biological profiles. However, traditional computational tools are limited in their ability to resolve this link because of the relatively small sizes of paired clinical–biological datasets for training and the high dimensionality/sparsity of tabular clinical data. Here, we use state-of-the-art foundation models (FMs) for electronic health record (EHR) data to generate proteomics profiles of pregnant patients, thereby deconvoluting pre-existing clinical information into biological profiles without the cost and effort of running large-scale traditional omics studies. We show that FM-derived representations of a patient’s EHR data coupled with a fully connected neural network prediction head can generate 206 blood protein expression levels. Interestingly, these proteins were enriched for developmental pathways, while proteins not able to be generated from EHR data were enriched for metabolic pathways. Finally, we show a proteomic signature of gestational diabetes that includes proteins with established and novel links to gestational diabetes. These results showcase the power of FM-derived EHR representations in efficiently generating biological states of pregnant patients. This capability can revolutionize disease understanding and therapeutic development, offering a cost-effective, time-efficient, and less invasive alternative to traditional methods of generating proteomics.
