Grafted transnationalism: Rhythmic routines and disruptions of stay‐at‐home international students
Authors: Cai Siman , Fang Zhilan 
Published: September 2023

AbstractDespite the lifting of COVID‐19 restrictions eventually, the destabilising consequences of the pandemic on migration persist and continue to worsen. Based on in‐depth interviews with 25 Chinese international students, this paper asks what new forms of education transnationality are being introduced by the intersection of digital mobility and physical immobility. Using Henri Lefebvre's (2004) rhythmanalysis, we understand stay‐at‐home international students' sensual and physical experiences as palpable aspects of daily existence that not only constitute transnational lived temporalities but also trigger ‘small accidents’, leading to potentially larger‐scale temporal changes. By attending to the dynamic interaction between their agency and the external structure, we conclude that situated corporeal and emotional suffering, embodied transitioning strategies, and changes to mobility pathways make up the fabric of the immobile everydayness of the new ‘grafted transnationalism’. This paper contributes to the existing scholarship on transnational education by highlighting the dual sense of exclusion that students experience in both corporeal and social time, as well as the multilayered possibilities of reorientation as their way of regaining control of dyssynchronous rhythmic encounters. It also sorts out the implications of lifetime geography on students’ differentially distributed vulnerability and susceptibility when facing life course disruptions.
Almost output regulation for turbofan switched systems under multi‐source disturbances and time delay
Authors: Liu Fan , Chen Mou , Shi Shuang , Li Tao 
Published: September 2023

AbstractIn allusion to the multi‐variable robust control for the turbofan engine with the large envelope, an almost output regulation (AOR) problem is discussed for a class of turbofan switched systems under multi‐source disturbances and time delay. The addressed disturbances include the regulated disturbance signal, the modeled disturbance from the input channel and the energy‐bounded disturbance. First of all, a disturbance observer is constructed to estimate the unknown disturbance in the system input. Then, by combining the output regulation method and the disturbance observer‐based control (DOBC) method, a switched composite regulation controller is developed to deal with the AOR problem of the turbofan switched systems and reject the adverse effects of disturbances. Through the multiple Lyapunov function method, a set of sufficient conditions are obtained to guarantee the AOR property with the performance and disturbance suppression ability. Finally, the validity of the proposed method is demonstrated by applying the composite anti‐disturbance regulator to the regulation of the speed and pressure ratio for the turbofan model.

AbstractSilicon nanocrystals (SiNCs) have attracted extensive attention in many advanced applications due to silicon's high natural abundance, low toxicity, and impressive optical properties. However, these applications are mainly focused on fluorescent SiNCs, little attention is paid to SiNCs with room‐temperature phosphorescence (RTP) and their relative applications, especially water‐dispersed ones. Herein, this work presents water‐dispersible RTP SiNCs (UA‐SiNCs) and their optical applications. The UA‐SiNCs with a uniform particle size of 2.8 nm are prepared by thermal hydrosilylation between hydrogen‐terminated SiNCs (H‐SiNCs) and 10‐undecenoic acid (UA). Interestingly, the resultant UA‐SiNCs can exhibit tunable long‐lived RTP with an average lifetime of 0.85 s. The RTP feature of the UA‐SiNCs is confirmed to the n—π* transitions of their surface C═O groups. Subsequently, new dual‐modal emissive UA‐SiNCs‐based ink is fabricated by blending with sodium alginate (SA) as the binder. The customized anticounterfeiting labels are also prepared on cellulosic substrates by screen‐printing technique. As expected, UA‐SiNCs/SA ink exhibits excellent practicability in anticounterfeiting applications. These findings will trigger the rapid development of RTP SiNCs, envisioning enormous potential in future advanced applications such as high‐level anti‐counterfeiting, information encryption, and so forth.

AbstractSodium–potassium (NaK) alloy electrodes are ideal for next‐generation dendrite‐free alkali metal electrodes due to their dendrite‐free nature. However, issues such as slow diffusion kinetics due to the large K+ radius and the loss of active potassium during the reaction severely limit its application. Here a novel cobalt/nitrogen‐doped carbon material is designed and it is applied to the construction of a NaK alloy electrode. The experimental and theoretical results indicate that the confining effect of the nitrogen‐doped graphitic carbon layer can protect the cobalt nanoparticles from corrosion leaching, while the presence of Co─Nx bonds and cobalt nanoparticles provides more active sites for the reaction, realizing the synergistic effect of adsorption‐catalytic modulation, lowering the K+ diffusion energy barrier and promoting charge transfer and ion diffusion. The application of this electrode to a symmetrical battery can achieve more than 1800 stable cycles under a current density of 0.4 mA cm−2 and a charge/discharge specific capacity of 122.64 mAh g−1 under a current of 0.5C in a full battery. This finding provides a new idea to realize a fast, stable, and efficient application of NaK alloy electrodes.

AbstractMolybdenum disulfide (MoS2), a metal dichalcogenide, is a promising channel material for highly integrated scalable transistors. However, intrinsic donor defect states, such as sulfur vacancies (Vs), can degrade the channel properties and lead to undesired n‐doping. A method for healing the donor defect states in monolayer MoS2is proposed using oxygen plasma, with an aluminum oxide (Al2O3) barrier layer that protects the MoS2channel from damage by plasma treatment. Successful healing of donor defect states in MoS2by oxygen atoms, even in the presence of an Al2O3barrier layer, is confirmed by X‐ray photoelectron spectroscopy, photoluminescence, and Raman spectroscopy. Despite the decrease in 2D sheet carrier concentration (Δn2D= −3.82×1012cm−2), the proposed approach increases the on‐current and mobility by 18% and 44% under optimal conditions, respectively. Metal–insulator transition occurs at electron concentrations of 5.7×1012cm−2and reflects improved channel quality. Finally, the activation energy (Ea) reduces at all the gate voltages (VG) owing to a decrease in Vs, which act as a localized state after the oxygen plasma treatment. This study demonstrates the feasibility of plasma‐assisted healing of defects in 2D materials and electrical property enhancement and paves the way for the development of next‐generation electronic devices.
Python meets JIT compilers: A simple implementation and a comparative evaluation
Authors: Zhang Qiang , Xu Lei , Xu Baowen 
Published: September 2023

AbstractDeveloping a just‐in‐time (JIT) compiler can be a daunting task, especially for a language as flexible as Python. While PyPy, powered with JIT compilation, can often outperform the official pure interpreter, CPython, by a noteworthy margin, its popularity remains far from comparable to that of CPython due to some issues. Given that an easier‐to‐deploy and better‐compatible JIT compiler would benefit more Python users, we have developed comPyler, a simple JIT compiler functioning as a CPython extension and intended to convert frequently interpreted CPython bytecode into equivalent machine code. Designed with good compatibility in mind, it does not alter CPython's internal data structures or external interfaces. Based on LLVM's mature infrastructure, it can be readily ported to almost all platforms. Compared with CPython, it achieved the highest speedup of 2.205, with an average of 1.093. Despite its relatively limited effect, comPyler incurs low development costs. As a baseline compiler, it also sheds light on the improvement attainable by optimizing solely the overhead of bytecode interpretation. Furthermore, as there is still a dearth of empirical research covering the multitude of JIT compilers available for Python, we have conducted a performance study that examines Jython, IronPython, PyPy, GraalPy, Pyston, Pyjion, and our comPyler. Our research takes into account not only the benchmark speed for various time windows but also the boot latency and memory footprint. Through this comprehensive study, our objective is to assist developers in gaining a better understanding of the effects of distinct JIT compilation techniques and to aid users in making informed decisions when choosing among different Python implementations.

Published: September 2023

AbstractRecently, urban agriculture has spread rapidly in occidental cities taking the form of plant cultivation on the rooftops of urban buildings. In this context, it would be interesting to use a natural fertilizer present in cities like the pigeon (Columba livia) guano. In this study, we tested the effects of pigeon guano on the cherry tomato plant in an urban environment. On a rooftop at Ivry‐sur‐Seine (near Paris, France), we set up 30 cultivation bags (58.9 L volume) with two cherry tomato plants in each bag. In June 2017, we added about 15 g of pigeon guano in 1.5 L of water to each of the 15 “guano” bags and 1.5 L of water to each of the 15 “control” bags. After 15 days, we observed that the tomato plants were higher and tend to have more flowers in the guano treatment than in the control group. Finally, regarding the total number of cherry tomatoes harvested (total mass and number), it was around one to two times higher in the guano treatment than in the control. However, the average mass per fruit was not affected by the treatment. Overall, we showed that pigeon guano is an efficient local fertilizer for cherry tomato plants in urban areas.

AbstractMathematical simulation of biological fluids is of upmost significance due to its numerous medical uses. Interpreting various biological flows necessitates a thorough knowledge of the peristaltic mechanism. This paper presents a computational study for the peristaltic pumping within vertical asymmetric channels filled with BN‐EG nanofluid under the influence of temperature‐dependent electrical conductivity and thermal radiation. Experimental study showed that the nanofluid created by suspending Boron Nitride particles in a combination of Ethylene Glycol exhibited non‐Newtonian characteristics. Further, the Carreau's fluid model provides accurate predictions about the rheological properties of BN‐EG nanofluid. Various configurations of the outer boundaries are considered, namely, square wave, multi‐sinusoidal wave, trapezoidal wave, and triangular wave. A uniform magnetic field together with nanoparticles and mass concentrations, joule heating, first‐order chemical reaction as well as viscous dissipation are considered. Influences of the Dufour and Soret numbers are examined, and the cases of biological scientific assumptions which is known as low Reynolds number and long wavelength are applied. All the computations are obtained numerically using Mathematica symbolical software (ND‐Solve), and the obtained results are presented in terms of the axial velocity u, heat transfer rate Z, concentration profile Ω, temperature profile θ, extra stress tensor , pressure gradient , pressure rise and stream function ψ. The major outcomes revealed that the maximizing in electrical conductivity coefficient, variable viscosity coefficient and magnetic field parameter is better to obtain a higher rate of the heat transfer while the increase in thermo‐diffusion effects as well as linear thermal radiation coefficient causes a reduction in the rate of heat transfer.
Thermal evaluation of MHD boundary‐layer flow of hybridity nanofluid via a 3D sinusoidal cylinder
Authors: Elsaid Essam M. , Abdel‐Wahed Mohamed S. 
Published: September 2023

AbstractThe study of the boundary layer is considered one of the most important theories in the field of heat and mass transfer because of its important explanation that shows us the behavior of different surfaces while they are under the influence of the flow accompanied by different thermal forces. The study of corrugated surfaces is one of the engineering applications, such as flow in heat exchangers or solar cells or cooling processes during surface heat treatments. This model is also used in medical applications such as flow in arteries or movement in the intestines. So, the work deals with investigating the boundary layer surrounding a three‐dimensional sinusoidal pipe; the boundary layer was assumed to be filled with a hybrid nanofluid consisting of water +Cu nanoparticles as the main fluid, supported by a small concentration of Al2O3 or Ag nanoparticles. The boundary layer is described by a set of nonlinear partial differential equations due to the continuity, momentum, and energy equations, which are transformed into a set of dependently coupled nonlinear ordinary differential equations. The obtained system of equations was solved using numerical techniques. The behavior of the boundary layer under the varying types and concentrations of nanoparticles and the influence of the magnetic field has been depicted by a set of graphs and tables. With reference to some results, it is found that using 5% of nanoparticles of aluminum oxide raises the rate of cooling by 8% and using 5% of silver nanoparticles increases it by 5%.
Die katholische Welt und die Urologie im 20./21. Jahrhundert
Authors: Mildenberger Florian G. 
Published: September 2023

ZusammenfassungDie katholische Welt ist geprägt durch päpstliche Vorgaben und ihre Interpretation im Wandel der Zeit durch berufene Theologen. Es bestehen strenge Verbote bei zentralen Fragestellungen über Leben und Tod, aber im Rahmen der praktischen Anwendung ärztlicher Behandlungstechniken bleibt der Vatikan häufig vage. Dies kann katholischen Urologen erlauben, eine Reihe von Therapien anzuwenden, die auf den ersten Blick problematisch erscheinen. Bedienen sich die Ärzte zudem einer anderen Ausdrucksweise als derjenigen, die in der Glaubenslehre genannt wird, besteht ein größerer Handlungsspielraum.
Impact of light pollution on aquatic invertebrates: Behavioral responses and ecological consequences
Authors: Ganguly Anirban , Candolin Ulrika 
Published: September 2023

Abstract
Artificial light at night (ALAN) is a growing global problem altering the behavior of organisms and thereby community composition and ecosystem processes. Research has mostly focused on terrestrial ecosystems, but a growing number of studies show that aquatic ecosystems are increasingly affected. Here, we provide a conceptual framework that describes how ALAN can influence aquatic ecosystems through effects on the behavior of ecologically important invertebrates. These organisms provide a range of critical ecological functions, from serving as food for other organisms to nutrient cycling and the translocation of energy and matter within and between ecosystems. In addition, we systematically searched the literature to assess the current state of the field and identify knowledge gaps. The literature search reveals that an increasing number of studies find light pollution to alter the behavior of aquatic invertebrates, such as their movements, habitat choice, and foraging behavior, but that the fitness consequences of these behavioral changes are largely unknown, as are their impacts on populations, communities, and ecosystems. Yet, assessing the consequences of behavioral changes for higher ecological levels is of vital importance given the central role of these invertebrates in ecosystems. Thus, more research needs to be directed to the ecological consequences of behavioral responses of aquatic invertebrates to light pollution. Overall, more effort should be made to assess the ecological consequences of behavioral responses to ALAN, and, importantly, how negative effects of light pollution could be mitigated.

Significance statement
Light pollution is of growing ecological concern and influencing ecosystems through effects on the behavior of organisms. Aquatic ecosystems are increasingly exposed and an ecologically important group of organisms in these systems are invertebrates. Here, we discuss how artificial light at night alters the behavior of aquatic invertebrates and how this in turn influences ecosystem structure and function. Such an understanding of the mechanisms and pathways that underlie the effect of light pollution on aquatic ecosystems is needed if we are to develop efficient strategies to reduce negative effects of human-made lighting systems on ecosystems.
Experimental study on the ablation of stainless steel using multiple ultra-short laser pulses with tunable time delays

Published: September 2023

AbstractResults on the ablation of stainless steel using ultra-short single, double and quadruple pulses as a function of the fluence and the time delay between each laser pulse are presented. The investigations focused quantitatively on the ablated volume and the resulting ablation efficiency, and qualitatively on the topography of the structures produced, providing insights about physical mechanisms such as shielding, re-deposition of ablated particles, and accumulation of heat or energy. The results indicate a significant influence of fluence in combination with the time delay on the ablation process and the resulting ablation topography.

Abstract
Background
Cerebral amyloid angiopathy (CAA) is associated with cognitive impairment, but the contributions of lobar intracerebral haemorrhage (ICH), underlying diffuse vasculopathy, and neurodegeneration, remain uncertain. We investigated the domain-specific neuropsychological profile of CAA with and without ICH, and their associations with structural neuroimaging features.

Methods
Data were collected from patients with possible or probable CAA attending a specialist outpatient clinic. Patients completed standardised neuropsychological assessment covering seven domains. MRI scans were scored for markers of cerebral small vessel disease and neurodegeneration. Patients were grouped into those with and without a macro-haemorrhage (CAA-ICH and CAA-non-ICH).

Results
We included 77 participants (mean age 72, 65% male). 26/32 (81%) CAA-non-ICH patients and 41/45 (91%) CAA-ICH patients were impaired in at least one cognitive domain. Verbal IQ and non-verbal IQ were the most frequently impaired, followed by executive functions and processing speed. We found no significant differences in the frequency of impairment across domains between the two groups. Medial temporal atrophy was the imaging feature most consistently associated with cognitive impairment (both overall and in individual domains) in both univariable and multivariable analyses.

Discussion
Cognitive impairment is common in CAA, even in the absence of ICH, suggesting a key role for diffuse processes related to small vessel disease and/or neurodegeneration. Our findings indicate that neurodegeneration, possibly due to co-existing Alzheimer’s disease pathology, may be the most important contributor. The observation that general intelligence is the most frequently affected domain suggests that CAA has a generalised rather than focal cognitive impact.

AbstractThe intake of omega-3 polyunsaturated fatty acids, including eicosapentaenoic acid (EPA), is associated with health benefits due to its anti-inflammatory properties. This fatty acid also exhibits antifungal properties in vitro. In order to determine if this antifungal property is valid in vivo, we examined how EPA affects Candidaalbicans pathogenesis in the Caenorhabditiselegans infection model, an alternative to mammalian host models. The nematodes were supplemented with EPA prior to infection, and the influence of EPA on C.elegans lipid metabolism, survival and immune response was studied. In addition, the influence of EPA on hyphal formation in C.albicans was investigated. It was discovered that EPA supplementation changed the lipid composition, but not the unsaturation index of C.elegans by regulating genes involved in fatty acid and eicosanoid production. EPA supplementation also delayed killing of C.elegans by C.albicans due to the inhibition of hyphal formation in vivo, via the action of the eicosanoid metabolite of EPA, 17,18-epoxyeicosatetraenoic acid. Moreover, EPA supplementation also caused differential expression of biofilm-related gene expression in C.albicans and stimulated the immune response of C.elegans. This provides a link between EPA and host susceptibility to microbial infection in this model.
