Experimental timing and control using microcontrollers
Authors: Starkey Philip T. , Turnbaugh Carter , Miller Patrick , LeBlanc Kermit-James , Meyer David H. 
Published: October 2024

Modern physics experiments rely on precise timing provided by programmable digital pulse generators. In many experimental control systems, this role is filled by custom devices built on field-programmable gate arrays. While highly flexible and performant, these devices can be difficult to scale to very large systems due to cost and complexity. Recent advances in microcontroller systems allow these much simpler devices to fill the role of digital pulse generators. Here, we demonstrate one such alternative based on the Raspberry Pi Pico microcontroller, which allows for timing resolution down to 7.5 ns with a minimum pulse width of 37.5 ns.
Manifestation of surfactant–carrier interaction in ferrofluids in temperature-dependent magnetic rheology
Authors: Upadhyay R. V. , Parekh Kinnari H. , Jadav Mudra , Lin Yu-Shen , Raj K. 
Published: October 2024

The present study investigates surfactant–carrier interactions in non-aqueous ferrofluids with magneto-rheology at different temperatures. To the authors’ knowledge, such a study has not yet been reported. For this purpose, three ferrofluids—A, B, and C—were procured from Ferrotec, which had identical particles but different surfactant–carrier combinations. The study also encompasses structural and magnetic techniques to elucidate these samples’ physicochemical nature. The results show that the average magnetic size of particles (10 nm) is the same for all the three fluids. The nominal value of the surfactant chain length (4.5 nm) was derived from dynamic light scattering measurements, and the Rosensweig viscosity model and the Shliomis theory were the same. The magneto-rheological properties, e.g., shear stress vs shear rate in zero field and relative increase in ferrofluid viscosity in the applied field at two different temperatures (300 and 313 K), were fitted with Rosensweig and Shliomis models. They showed some variations in surfactant chain lengths. The results suggested the presence of surfactant–carrier interactions in these colloids. This new investigation may be useful in characterizing the stability of a ferrofluid and its practical aspects.
Experimental study on spheroidal morphology of palladium coated copper wire with different palladium layer thickness

Published: October 2024

Palladium (Pd) coated copper (PCC) wire is an emerging bonding wire that has been widely researched. In this paper, the effects of electronic flame-off (EFO) current and EFO time on the free air ball (FAB) morphology of four PCC wires with Pd layer thicknesses of 60, 80, 100, and 120 nm, respectively, are first investigated. The larger the EFO current or the longer the EFO time, the larger the FAB diameter. The EFO time or EFO current setting is either too high or too low to form a FAB with good morphology. Taking the ratio of FAB diameter to wire diameter as 2 as the standard, the EFO current of 48 mA and the EFO time of 700 μs are selected as the optimal EFO parameter combination. Under this parameter combination, the symmetry, roundness, and surface smoothness of the FAB of the four PCC wires are all at a better level. It is found that the FAB surface Pd coverage of PCC wire with 120 nm Pd layer thickness is higher through the corrosion test. The Pd transfer law on the FAB at different EFO times under optimal EFO current is also studied. The results show that with the prolongation of the EFO time, the Pd on the FAB surface is gradually transferred from the neck to the middle and lower parts. This study can provide technical reference for the selection of Pd layer thickness and EFO parameters of PCC wire.
“The East I Know”
Authors: Yuan Weishi 
Published: October 2024

Abstract
This chapter analyses the forms of cultural transfer in Richard Wilhelm’s (1873–1930) China travel
writings, brought together in The Soul of China (1925), with a specific focus on the transmission of the
concept of “soul.” It examines the two-way transmission of this concept between the East and the West. In The Soul of
China, Wilhelm created contact zones, which can be understood as a complex entanglement of different mind-sets at
the beginning of the twentieth century after a series of social changes in both Germany and China. By means of The
Soul of China, Wilhelm was determined to appeal to the influential analytical psychology in Europe and to
illustrate the ancient spiritual laws of Chinese philosophy, primarily in response to the prevailing European esoteric
movement, as well as to the abandonment of Confucianism in China. Wilhelm’s earlier translation of The Secret of the
Golden Flower demonstrated that, in parallel with the soul of the West, there was also a soul of China, which
could be understood as consisting of consciousness and unconsciousness. However, part of the soul of China, that element which
was shaped by the ancient spiritual laws as found in Wilhelm’s translation of the I Ching, had not yet been
discovered or appropriated by the West. Ultimately, the exchange of the concept of soul was mediated by the construal of a
traveller-narrator in the contact zones which Wilhelm created in The Soul of China.
Good migrations?
Authors: Hedberg Andreas 
Published: October 2024

Abstract
The paragon of the Swedish author (and later Nobel prize laureate) Harry Martinson’s early travel writing,
published in the 1930s, is the “geosopher,” a figure that has broken free of the confines of his birth nation and its culture
in order to experience the world in its entirety. For the geosopher, travelling is a basic need.
Martinson’s ideal, based on his own experiences as a ship stoker, was made possible by modern
transportation, technology, commerce and cultural transfer on a new scale – phenomena that for some of his contemporaries
seemed more frightening than promising, uprooting them from traditional life. Today, in the wake of climate change, the fear
of pandemics and large-scale migration, these anxieties have resurfaced.
Even though Martinson seemed optimistic about his geosopher ideal, he soon gave up his life as a migrant
and turned to the Swedish countryside, where the global perspective of his travel writing was replaced by an interest in the
smallest creatures and movements of nature. When he later returned to the theme of travelling, it was with a completely
different tone in the dystopic fantasies of the “space epic” Aniara.
In this article, I will explore the shifting attitudes in Martinson’s travel writing, and also relate them
to our contemporary challenges: migration, climate change and the Covid-19 pandemic. How can literature contribute to cultural
transfer and border crossings in an age where mobility has to be limited?
What the acquisition of Japanese vs. Chinese contributes to generative approaches to SLA
Authors: Hirakawa Makiko 
Published: October 2024

Abstract
This paper draws on data from previous findings on L2 Japanese and L2 Chinese. In particular, it
investigates the role of Strong Uniformity (Miyagawa, 2009, 2017) in explaining an asymmetry in the L2 acquisition of Japanese and
Chinese. The studies focus on three linguistic structures: person restrictions on null subjects, contrastive topics,
and blocking on long-distance (LD) binding construal, all of which relate to the interface between syntax and
discourse, an area known to cause difficulties for language learners (Sorace,
2011). It is suggested that the differences in L1 Chinese and L1 Japanese participant performance in L2
Japanese and Chinese, respectively, can be explained by differences in their ability to acquire new φ-features and
inheritance in their respective target languages.
Revisiting plurality in SLA
Authors: Ionin Tania , Atiles Amy Yuiko , Choi Sea Hee , Lee Chae Eun , Wu Mien-Jen 
Published: October 2024

Abstract
This paper reports on the production and comprehension of English singular and plural NPs by
L2-English learners whose L1, Mandarin Chinese, does not have obligatory plural marking. This study has the following
objectives: (1) To systematically investigate both production and comprehension of plural marking with this
population; (2) to examine whether learners can become target-like in their production and comprehension of English
plural marking with increased proficiency; and (3) to examine whether learners’ performance depends on the available
cues to plurality. The results paint a nuanced picture: while overall less accurate than native speakers, learners do
show evidence of the English plural marker being integrated into their grammar, and also exhibit improvement with
proficiency.
Structural change and ambiguity resolution in L2 learners of English
Authors: Fang Shaohua 
Published: October 2024

Abstract
This study investigated the influence of structural changes for verbs in second language (L2)
ambiguity resolution. Two types of verbs were examined: those taking a noun phrase (NP) or no complements (Z) (e.g.,
to type, NP/Z verbs), and those taking either an (NP) or a sentence (S) (e.g., to
understand, NP/S verbs). A self-paced reading experiment found that Chinese-speaking learners of English,
like first-language (L1) English speakers, took longer to process disambiguating regions in ambiguous sentences
compared to corresponding regions in unambiguous sentences. Moreover, NP/Z verbs posed greater difficulty than NP/S
verbs, especially in ambiguous sentences, for both speaker groups. This suggests a garden-path effect in learners,
indicating that structural information from verbs influences L2 processing similarly to L1 processing.
Sensitivity to event structure in passives supports deep processing in L1 and L2
Authors: Geraghty Katrina , Grillo Nino , Sloggett Shayne 
Published: October 2024

Abstract
A key question in second language research is whether native (L1) and non-native (L2) sentence
processing are fundamentally different. Recent L1 research has questioned the assumption that passives are harder to
process than actives: passive complexity appears to be determined by event structure (Paolazzi et al., 2019; Paolazzi et al., 2021). We
replicate these results using a maze task; only passives of states appear to be more difficult to process than
actives, inconsistent with a Good-Enough account. We also present evidence that L2 learners can recruit similarly
nuanced processing mechanisms in understanding passives. L2 learners display the same interaction of event structure
and passivization. Taken together, the results appear inconsistent with shallow processing accounts of both L1 and L2
processing.
There isn’t a problem with indefinites in existential constructions in L2-English
Authors: Ionin Tania , Chen Chung-yu 
Published: October 2024

Abstract
This is an exploratory study of how both native English speakers and L1-Mandarin L2-English
learners judge different types of indefinites in both existential there-constructions and copular
constructions with an indefinite subject. Unlike English, Mandarin lacks an a/one distinction, has
two different types of existential constructions, and lacks numeral partitives. It is argued that target
differentiation among indefinite types and syntactic constructions presents a Poverty of the Stimulus problem.
Learners are found to overcome this problem: while there is limited evidence of L1-transfer from Mandarin to English,
the learners largely exhibit the same patterns as native speakers in an acceptability judgment task. It is argued that
a universal Gricean principle helps learners acquire the a/one distinction.

Published: October 2024

Abstract
This chapter explores bi-/multilingualism in the Indian context, summarizing findings from the
MultiLiLa project which addressed the persistent challenge of low learning outcomes in India. The research covered
diverse geographical settings and employed a comprehensive methodology. We present quantitative findings from
classroom observations, emphasizing the extent of English input in primary school. Linking learners’ home language
profiles, school language exposure, and performance on cognitive and linguistic tasks, the chapter also explores
English narrative retellings as a lens for understanding the use of vocabulary and morphosyntax. The findings provide
valuable insights into the dynamics of language input and its implications for bilingual education in India. The
chapter contributes to the broader discourse on bilingualism and sets the stage for future research.
Venus’s phases: evidence supporting heliocentrism
Authors: Giudici Sergio 
Published: October 2024

Abstract
The affirmation of the Copernican system marks a milestone in the history of science. However, in educational settings, theoretical and philosophical aspects are often prioritized, with less attention paid to the empirical and quantitative data supporting heliocentrism. The discovery of Venus phases by Galileo Galilei through his early telescope represents a compelling piece of evidence corroborating the Sun-centered model. A renowned drawing published in Galilei's treatise ‘Il Saggiatore’ (1623) illustrates this phenomenon and the anti-correlation between phases and apparent diameter. The analysis of the illustration reveals precise quantitative information comparable in accuracy to that which can be extracted from contemporary astrophotography. Inspired by this result, the galileian discovery has been revisited and tailored into activities suitable for both high school and college teaching levels. These activities invite students to construct their own empirical evidence for heliocentrism by analyzing digital images and using interactive digital tools for image manipulation. The topic has also been proposed at the university level through more advanced analysis techniques. The common aim at each level is to engage students in a dynamic ‘learning by doing’ experience, replicating pivotal moments from the history of science and transforming a topic traditionally confined to the history of ideas into a living, interactive subject.
Luminescent nanomaterials for developing high-contrast latent fingerprints
Authors: Swati G , Mishra Savvi 
Published: October 2024

Abstract
Fingerprint patterns (or epidermal ridges) are by far one of the most reliable techniques for individual identification. Fingerprint patterns get deposited on all kinds of solid surfaces due to human transudation or exudation process. Bodily fluids through sweat glands contain moisture, natural oils and proteins. Since latent fingerprint patterns are not readily recognizable they are collected from a crime scene and are further processed physically or chemically. Fingerprints obtained using conventional black and white powders face severe drawbacks including low sensitivity, high background interference from the substrates, involvement of toxic materials, and poor stability. To overcome the above-listed issues, especially for coloured and transparent substrates, luminescent materials have emerged as potential agents for rapid visualization of high-contrast latent fingerprints. This review covers the recent advancements in luminescent nanomaterials of both kinds (up and down conversion) and persistent nanophosphors for developing latent fingerprints. Special emphasis has been given to an unusual class of luminescent materials known as persistent nanophosphors, which do not require a constant excitation, thereby completely eradicating background noise. The review also covers different approaches to gathering fingerprints such as powder dusting, cyanoacrylate fuming, ninhydrin fuming and vacuum metal deposition.

Published: October 2024

Abstract
A kind of antistatic coatings which were applied to nonconductive surfaces were prepared with Polytetrafluoroethylene (PTFE) as matrix, modified carbon black (CB) as conductive filler. Compared to sodium dodecyl sulfate, poly(vinyl pyrrolidone), the TMN-10 modified CB has better wettability, dispersion, stability and re-disperse. When CBTMN-10 content is 5 wt.%, the surface resistivity of coating reach to 106 Ω*cm, which denotes the coating performance good antistatic behavior. The antistatic coating of 5 wt.% CBTMN-10 content is found to exhibit excellent hydrophobicity and high HV hardness. Meanwhile, the low average friction coefficients and wear rate were achieved in antistatic coating of 5 wt.% CBTMN-10 content. Furthermore, compared to MXene, reduced graphene oxide, carbon nanotube, the modified CB as conductive material in PTFE antistatic materials could be an useful way not only excellent properties but also large-scale production as well as a reduction in unit cost in antistatic materials.
A transforming flexahedron origami inspired gripper actuated by shape memory alloy
Authors: Pan Jie , Cheng Yongfeng , Jiang Ming , Xia Yongjun , Yu Jingjun , Pei Xu 
Published: October 2024

Abstract
The transforming flexahedron origami (TFO) is a unique origami that combines the functions of fingers and palm, with a symmetrical distribution of four-finger structures and good shape adaptability. In this paper, inspired by the TFO configuration, a new type of reconfigurable gripper is designed. The kinematics and mechanics of the gripper are analyzed theoretically, and paper folding is used as the skeleton, thin film as the skin, shape memory alloy spring as the actuator, and active cooling is used to enhance the actuator efficiency. Different kinds of objects are used to test the gripping performance of the gripper, including shape adaptive ability and gripping robustness test, and the test results show that the gripper is with good gripping performance. The reconfigurable capability of the TFO configuration allows the hand gripper to have two gripping modes, adapting to the adaptive gripping of thin rod-like objects and curved objects, which is difficult to achieve with a single gripping mode. The TFO gripper provides a new way of thinking for the design of flexible and origami grippers in the future.
Remarks on 2D quantum cosmology
Authors: Anninos Dionysios , Baracco Chiara , Mühlmann Beatrix 
Published: October 2024

AbstractWe consider two-dimensional quantum gravity endowed with a positive cosmological constant and coupled to a conformal field theory of large and positive central charge. We study cosmological properties at the classical and quantum level. We provide a complete ADM analysis of the classical phase space, revealing a family of either bouncing or big bang/crunch type cosmologies. At the quantum level, we solve the Wheeler-DeWitt equation exactly. In the semiclassical limit, we link the Wheeler-DeWitt state space to the classical phase space. Wavefunctionals of the Hartle-Hawking and Vilenkin type are identified, and we uncover a quantum version of the bouncing spacetime. We retrieve the Hartle-Hawking wavefunction from the disk path integral of timelike Liouville theory. To do so, we must select a particular contour in the space of complexified fields. The quantum information content of the big bang cosmology is discussed, and contrasted with the de Sitter horizon entropy as computed by a gravitational path integral over the two-sphere.
Universal relations for anisotropic interacting quark stars
Authors: Pretel Juan M.Z. , Zhang Chen 
Published: October 2024

Abstract
Interacting quark stars, which are entirely composed of interacting quark matter including
perturbative QCD corrections and color superconductivity, can meet constraints from various pulsar
observations. In realistic scenarios, pressure anisotropies are expected in the star's
interior. Recently, the stellar structural properties of anisotropic interacting quark stars have
been investigated. In this study, we further explore the universal relations (URs) related to the
moment of inertia I, tidal deformability Λ, compactness C, and the f-mode nonradial
pulsation frequency for such stars. Our results reveal that these approximate URs generally hold,
being insensitive to both the EOS variations as well as to the presence of anisotropy. In contrast
to previous studies on anisotropic neutron stars, we find that more positive anisotropy tends to
enhance the I-Λ and I-C URs, but weakens the C-Λ UR. For all the URs involving
f-mode frequency, we find that they are enhanced by the inclusion of anisotropy (whether
positive or negative). Utilizing these URs and the tidal deformability constraint from the
GW170817 event, we put limits on the structural properties of isotropic and anisotropic quark
stars, such as the moment of inertia I
1.4, the canonical radius R
1.4 and the canonical
f-mode frequency f

f,1.4, all of which are very different compared to those of
neutron stars.
An extended (2+1)-dimensional modified Korteweg–de Vries–Calogero–Bogoyavlenskii–Schiff equation: Lax pair and Darboux transformation
Authors: Cheng Li , Zhang Yi , Ma Wen-Xiu 
Published: October 2024

Abstract
The aim of this paper is to study an extended modified Korteweg–de Vries–Calogero–Bogoyavlenskii–Schiff (mKdV-CBS) equation and present its Lax pair with a spectral parameter. Meanwhile, a Miura transformation is explored, which reveals the relationship between solutions of the extended mKdV-CBS equation and the extended (2+1)-dimensional Korteweg–de Vries (KdV) equation. On the basis of the obtained Lax pair and the existing research results, the Darboux transformation is derived, which plays a crucial role in presenting soliton solutions. In addition, soliton molecules are given by the velocity resonance mechanism.

Abstract
Radiative cooling materials have gained prominence as a zero-energy solution for mitigating global warming. However, a comprehensive understanding of the atomic-scale optical properties and macroscopic optical performance of radiative cooling materials remains elusive, limiting insight into the underlying physics of their optical response and cooling efficacy. La2O3 and HfO2, which represent rare earth and third/fourth subgroup inorganic oxides, respectively, show promise for radiative cooling applications. In this study, we used multiscale simulations to investigate the optical properties of La2O3 and HfO2 across a broad spectrum. First-principles calculations revealed their dielectric functions and intrinsic refractive indices, and the results indicated that the slightly smaller bandgap of La2O3 compared to HfO2 induces a higher refractive index in the solar band. Additionally, three-phonon scattering was found to provide more accurate infrared optical properties than two-phonon scattering, which enhanced the emissivity in the sky window. Monte Carlo simulations were also used to determine the macroscopic optical properties of La2O3 and HfO2 coatings. Based on the simulated results, we identified that the particle size and particle volume fraction play a dominant role in the optical properties. Our findings underscore the potential of La2O3 and HfO2 nanocomposites for environment-friendly cooling and offer a new approach for high-throughput screening of optical materials through multiscale simulations.
