A Rare Complication of Intraprosthetic Dissociation of Cemented Bipolar Hemiarthroplasty during Closed Hip Reduction: Case Report and Literature Review
Authors: Mitchell Amanda , Belkin Nicole , Sarpong Nana , Herndon Carl L. , Hickernell Thomas R. 
Published: January 2024

AbstractHip hemiarthroplasty (HA) remains a frequently performed surgery for femoral neck fractures especially in the oldest, lowest demand patients. Debate persists concerning the optimal choice between unipolar and bipolar HA implants. A rare but important to recognize complication unique to bipolar HA is intraprosthetic dissociation (IPD). We review the literature on this rare phenomenon and identify predominant etiologies and implant components most involved in IPD, notably the role of hip dislocation and closed reduction in precipitating this complication. We also describe an elderly male patient with Parkinson's who experienced IPD of his bipolar HA during a closed reduction attempt. IPD typically requires open reduction and possibly revision of components, adding increased risk of reoperation/revision to those already frail and vulnerable to surgical complications.

Published: January 2024

AbstractThe University of Michigan has played an important role in advancing gender-affirming surgery programs in the United States. The University of Michigan was home to a little-known gender identity clinic shortly after the opening of the first such clinic at Johns Hopkins. Since 1995, the University of Michigan Comprehensive Services Program (UMCGSP) has been continually offering surgical services to transgender and gender diverse patients. Here, we present the history of both programs, drawn from program documents and oral history, and explore their implications for the future sustainability of gender-affirming surgery programs. The original gender identity clinic opened in 1968, and operated in a multidisciplinary fashion, similar to other clinics at the time. Eventually, the clinic was closed due to disinvestment and lack of sufficient providers to maintain the program, problems which are being increasingly recognized as barriers for similar programs. The modern program, UMCGSP is perhaps the longest continually running gender-affirming surgical program at an academic center. In spite of challenges, key investments in education, statewide community engagement, and the development of a comprehensive care model have helped UMCGSP avoid the pitfalls of the earlier clinic and remain relevant throughout its nearly 30-year history. In the face of rising challenges to gender-affirming care in the United States, much can be learned from the sustainability of the UMCGSP. Institutions seeking to maintain gender-affirming surgery programs should ensure the availability of comprehensive care and promote the education of the health care workforce.

Objective This study evaluated the effects of receiving glucose feedback from continuous glucose monitoring (CGM) by intermittent scanning (unblinded group), and CGM with masked feedback (blinded group) in the subsequent development of gestational diabetes mellitus (GDM).
Study Design This was a prospective, single-center, pilot, randomized controlled trial including n = 206 pregnant women in the first trimester of pregnancy with no prior diagnosis of type 1 or type 2 diabetes. The participants were randomized into the unblinded group or blinded group and wore the CGM in the first trimester of pregnancy (9–13 weeks), the second trimester of pregnancy (18–23 weeks), and late-second to early-third trimester (24–31 weeks). The primary outcome was GDM rate as diagnosed by the 75-g oral glucose tolerance test (OGTT) at 24 to 28 weeks.
Results Over 47 months, 206 pregnant women were enrolled at 9 to 13 weeks. The unblinded group had a higher prevalence of women who developed GDM (21.5 vs. 14.9%; p > 0.05), compared to the blinded group. In the unblinded group compared to the blinded group, plasma glucose values were higher at 1 hour (median 7.7 [interquartile range {IQR}: 6.3–9.2] vs. 7.5 [6.3–8.7]) and 2 hours (6.3 [5.8–7.7] vs. 6.2 [5.3–7.2]), but lower at 0 hour (4.2 [4.0–4.5] vs. 4.3 [4.1–4.6]; p > 0.05). All these differences were not statistically significant.
Conclusion Glucose feedback from CGM wear in the first to the third trimester of pregnancy without personalized patient education failed to alter GDM rate.

Published: January 2024

AbstractIn the past decade, China has entered the process of universalization of higher education, however, with the popularization of higher education, the issue of education quality has become more important than ever. Therefore, the main objective of this study was to explore the relationship between learning motivation and learning effectiveness, the mediation effect of learning engagement on learning motivation and learning effectiveness, and the moderation effect of students’ personality traits on the relationship between learning motivation and learning effectiveness. It was found that (1) Learning motivation had a significant positive impact on learning effectiveness; (2) Learning motivation had a significant positive effect on learning engagement; (3) Learning engagement had a significant positive impact on learning effectiveness; (4) Learning engagement had a partial mediation effect on learning motivation and learning effectiveness. (5) Personality traits had a moderation effect on the relationship between learning motivation and learning effectiveness. It was suggested that college students should stimulate their motivation for independent learning, enhance their motivation for learning, and cultivate the ability to learn independently in learning. At the same time, in the classroom, teachers should innovate teaching methods, mobilize students’ interest in learning, and cultivate students’ initiative. In addition, schools should actively carry out themed lectures to cultivate students’ correct learning attitudes. In terms of the influence of personality traits on the relationship between learning motivation and learning effectiveness should not be ignored, and appropriate attention should be paid to improving learning effectiveness. Different personality traits should be further explored.

Understanding the pressure-induced structural changes in liquids and amorphous materials is fundamental in a wide range of scientific fields. However, experimental investigation of the structure of liquid and amorphous material under in situ high-pressure conditions is still limited due to the experimental difficulties. In particular, the range of the momentum transfer (Q) in the structure factor [S(Q)] measurement under high-pressure conditions has been limited at relatively low Q, which makes it difficult to conduct detailed structural analysis of liquid and amorphous material. Here, we show the in situ high-pressure pair distribution function measurement of liquid and glass by using the 100 keV pink beam. Structures of liquids and glasses are measured under in situ high-pressure conditions in the Paris–Edinburgh press by high-energy x-ray diffraction measurement using a double-slit collimation setup with a point detector. The experiment enables us to measure S(Q) of GeO2 and SiO2 glasses and liquid Ge at a wide range of Q up to 20–29 Å−1 under in situ high-pressure and high-temperature conditions, which is almost two times larger than that of the conventional high-pressure angle-dispersive x-ray diffraction measurement. The high-pressure experimental S(Q) precisely determined at a wide range of Q opens the way to investigate detailed structural features of liquids and amorphous materials under in situ high-pressure and high-temperature conditions, as well as ambient pressure study.
Anatomy of the dielectric behavior of methyl-m-toluate glasses during and after vapor deposition
Authors: Richert R. , Tracy M. E. , Guiseppi-Elie A. , Ediger M. D. 
Published: January 2024

Glassy films of methyl-m-toluate have been vapor deposited onto a substrate equipped with interdigitated electrodes, facilitating in situ dielectric relaxation measurements during and after deposition. Samples of 200 nm thickness have been deposited at rates of 0.1 nm/s at a variety of deposition temperatures between 40 K and Tg = 170 K. With increasing depth below the surface, the dielectric loss changes gradually from a value reflecting a mobile surface layer to that of the kinetically stable glass. The thickness of this more mobile layer varies from below 1 to beyond 10 nm as the deposition temperature is increased, and its average fictive temperature is near Tg for all deposition temperatures. Judged by the dielectric loss, the liquid-like portion of the surface layer exceeds a thickness of 1 nm only for deposition temperatures above 0.8Tg, where near-equilibrium glassy states are obtained. After deposition, the dielectric loss of the material positioned about 5–30 nm below the surface decreases for thousands of seconds of annealing time, whereas the bulk of the film remains unchanged.

Abstract
This study aims to investigate the image reconstrual of Shan Gui 山鬼 in the multimodal translation from the poem Shan Gui to three renowned
paintings, i.e., Li Gonglin’s 李公麟 (date unknown;
1049–1106), Fu Baoshi’s 傅抱石’s (1945) and Xu Beihong’s
徐悲鸿 (1943), within the framework of social semiotics,
and to explore the reason why the image changed through recontextualization. It is found that the image of Shan Gui reconstrued by
Li looks like a detached sprite; Fu is a sentimental goddess, while Xu is a mundane human girl. Contextual factors, including
scholastic explanations of the poem, the individual orientation of painters, and their media choices, contribute to such image
divergence.

Feedback enhanced Dyakonov–Shur instability in graphene field-effect transistors
Authors: Cosme Pedro , Simões Diogo 
Published: January 2024

Abstract
Graphene devices are known to have the potential to operate THz signals. In particular, graphene field-effect transistors (gFETs) have been proposed as devices to host plasmonic instabilities in the THz realm; for instance, Dyakonov–Shur (DS) instability which relies upon dc excitation. In this work, starting from a hydrodynamical description of the charge carriers, we extend the transmission line description of gFETs to a scheme with a positive feedback loop, also considering the effects of delay, which leads to the transcendental Laplace-transform transfer function, with complex frequency s, with terms of the form

. Applying the conditions for the excitation of DS instability, we report an enhanced voltage gain in the linear regime that is corroborated by our simulations of the nonlinear hydrodynamic model for the charge carriers. This translates to both greater saturation amplitude—often up to 50% increase—and faster growth rate of the self-oscillations. Thus, we bring forth a prospective concept for the realization of a THz oscillator suitable for future plasmonic circuitry.
Development of a modular system to provide confidence in porosity analysis of additively manufactured components using x-ray computed tomography

Abstract
X-ray computed tomography (XCT) offers a promising non-destructive method to assess high value components that are additively manufactured (AM) for space-based imaging. However, AM components can be often challenging to measure and the true resolution of the XCT system used is both non-trivial to determine and may change locally. To solve this, we used high precision micro-machining to manufacture a cylindrical reference pin with internal holes. This pin can then be inserted into any component via subtractive machining, prior to the XCT process. A pre-existing AM flexure is modified to allow our modular system to be implemented. This allows XCT scanning and porosity analysis of similar components (similar geometry and manufacturing process) to be refined and adjusted based on the known internal micro-machined hole size. Analysis of the XCT volumetric data is implemented using a Python script developed for Avizo 2022.1, to compare and suggest the ideal threshold grey value (GV). The plugin threshold comparison is semi-automatic and 15 times faster than a manual comparison. Study findings showed how different calibrated micro-machined hole sizes (30 μm–120 μm) needed different thresholding values (188 GV–195 GV). Challenges and future studies related to traceability of the suggested method are discussed.
Multi-condition stability analysis and lightweight research of mining wide-body dump truck compartment

Published: January 2024

Abstract
This paper proposes a multi-condition optimization method based on single condition optimization and weight. This method analyzes and discusses various working states of the wide-body dump truck and optimize its structure. Firstly, the modal shape and natural frequency of the carriage under modal conditions are analyzed using the finite element method. Combined with the mechanic’s theory, the carriage’s force, deformation, and stress are studied under the turning and partial load conditions. This part provides a basis for subsequent stability analysis and lightweight research. According to the filtering white noise method and differential equation method, the f-class road model and the vehicle system dynamics model are established in MATLAB to study the influence of road vibration on the stability of the dump truck during operation. The carriage vibration data prove that the road vibration causes the low order resonance of the carriage and affects the stability of the dump truck. This part provides a basis for the subsequent stability optimization. Based on the above analysis, a multi-objective genetic algorithm based on the response surface is used to optimize the structural parameters of the carriage under partial load conditions, turning conditions and modal conditions, to realize the optimization of stability, mass, stress and deformation of the carriage. Finally, the entropy weight method is used to fuse the optimization results of the three working conditions. The correctness of the comprehensive optimization results is verified, and the wide-body dump truck carriage optimization is realized, proving the feasibility of the proposed method.
The anisotropic transport properties of the three-terminal ballistic junction based on α−T
3 lattice
Authors: Xiao Ningyan , Duan Xian , Zhang Siyan , Zhou Benliang , Zhou Benhu 
Published: January 2024

Abstract
The three-terminal ballistic junction (TBJ) has promising applications in nanoelectronics. We investigate the transport properties of a α−T
3-based TBJ, where two typical configurations are considered, i.e. the A- and Z-TBJ. It is found that both A- and Z-TBJ exhibit transmission anisotropy, and the transmission of the A-TBJ has stronger anisotropy than that of the Z-TBJ. The amplitude of the rectification coefficient is smaller than that of phosphorene TBJ, but larger than that of graphene TBJ. When the symmetrical input is applied, the output voltage curve exhibits symmetric behavior. While in the case of asymmetric input, the symmetric behavior is broken, and the maximum value of the output voltage can reach a positive value. Interestingly, the voltage output shows a dramatic nonlinear response which may be useful for the voltage diode application with a push-pull input voltage. In addition, the heat fluxes of the asymmetric input are much smaller than those of the symmetric input. The maximum value of the heat flux under the symmetric input exceeds twice of that under the asymmetric input. Our results are useful to design nanoelectronic devices based on α−T
3 TBJ.
Structural stability of subsonic steady states to the hydrodynamic model for semiconductors with sonic boundary
Authors: Feng Yue-Hong , Hu Haifeng , Mei Ming 
Published: January 2024

Abstract
The hydrodynamic model for semiconductors with sonic boundary, represented by Euler–Poisson equations, possesses the various physical steady states including interior-subsonic/interior-supersonic/shock-transonic/C
1-smooth-transonic steady states. Since these physical steady states result in some serious singularities at the sonic boundary (their gradients are infinity), this makes that the structural stability for these physical solutions is more difficult and challenging, and has remained open as we know. In this paper, we investigate the structural stability of interior subsonic steady states. Namely, when the doping profiles are as small perturbations, the differences between the corresponding subsonic solutions are also small. To overcome the singularities at the sonic boundary, we propose a novel approach, which combines the weighted multiplier technique, local singularity analysis, monotonicity argument and squeezing skill. Both the result itself and the technique developed here will give us some truly enlightening insights into our follow-up study on the structural stability of the remaining types of solutions. A number of numerical approximations are also carried out, which intuitively confirm our theoretical results.
