A novel method for estrous cycle staging using supervised object detection
Authors: Babaev Benjamin , Goyal Saachi , Arora Tushar , Autry Anita , Ross Rachel A. 
Published: January 2025

AbstractThe estrous cycle regulates reproductive events and hormone changes in female mammals and is analogous to the menstrual cycle in humans. Monitoring this cycle is necessary as it serves as a biomarker for overall health and is crucial for interpreting study results. The estrous cycle comprises four stages influenced by fluctuating levels of hormones, mainly estradiol and progesterone. Tracking the cycle traditionally relies on vaginal cytology, which categorizes stages based on three epithelial cell concentrations. However, this method has limitations, including time-consuming training and variability among researchers. This study assesses the feasibility and reliability of two previous image classification models as well as introducing an alternative method of machine learning to address the challenges posed by manual vaginal cytology and image classification. An object detection-based machine learning model, Object Detection Estrous Staging (ODES), was employed to identify cell types throughout the estrous cycle in mice. A dataset of 730 vaginal cytology images with four different stains was used, with 335 images for training, 45 for validation, and 350 for testing. A novel, accurate set of rules for classification was derived by analyzing training images. ODES achieved an average accuracy of 80% in classifying cycle stages, comparable to human accuracy (66%) and previous image classification models (41–79%). The efficiency of ODES, processing 100 test images in just 2.67 minutes, makes it a valuable tool for large-scale neuropsychiatric studies involving female rodents and also encourages the integration of this variable into neurological and psychiatric research. These results demonstrate that ODES offers a fast, reliable, and accessible method for estrous cycle monitoring, potentially improving how researchers approach sex-based variables in neuropsychiatric studies.
A Look at the BOS-10 and H-1500 Oxygenators
Authors: Walton Howard G. , Sugden Ernest H. , White Judith A. 
Published: January 2025

Having experienced difficulty, from time to time, in obtaining certain oxygenators from manufacturers for various reasons, we were prompted to investigate the convenience and possibility of using two oxygenators on a routine basis. An evaluation of the Bentley Spiraflo BOS-10 and Harvey H-1500 oxygenators was undertaken to determine the ease of use and compare the performance of each in the areas of blood gases, flows, and heat transfer. The BOS-10 oxygenator and the H-1500 oxygenator were each used for fifty perfusions on patients requiring cardiopulmonary bypass for the correction of cardiac/coronary disease.
While there was no statistical difference in blood flow between the two oxygenators, there was a significant difference in gas flow employed. The Bentley BOS-10 was able to adequately oxygenate at a lower total gas flow, but unable to adequately remove the CO2 at these lower gas flows. There was no statistical difference in the arterial blood pO2. The BOS-10 outperformed the H-1500 oxygenator when warming times were compared. For this reason we have discontinued the use of the H-1500 in favor of the S-100A and BOS-10S. No problems were experienced in the routine use of two different bubble oxygenators. We believe that it is advantageous for an institution performing open-heart surgery to have at least two oxygenators available to the surgical team.
The retailer's information sharing decisions with manufacturer's encroachment and production learning effects
Authors: Hu Xingyu , Guan Zhenzhong , Ren Jianbiao 
Published: January 2025

If the manufacturer can efficiently reduce costs and boost overall profits throughout the supply chain, he can send some incremental surplus to the retailer to motivate him to share his precise demand information. We study a two-period dual-channel supply chain where a manufacturer sells through a retailer with an advantage in demand information. The manufacturer can encroach and use production learning effects to reduce costs. Based on six scenarios under the "encroachment-dominated + production-learning effect-dominated + dual-factor" approaches, we investigated how the manufacturer's encroachment and the production-learning effect affected the retailer's decisions to share information. Some interesting results are obtained. First, a single-win, win-win, or lose-lose situation is generated for the supply chain participants by the dynamic competition mechanism under the combined effects of encroachment and the production learning effect. When more ambiguous demand information is cooperatively provided, both the retailer and manufacturer will benefit from information sharing. The win-win area increases with higher direct selling costs, whereas the win-win area decreases with increased production learning effects. Second, the retailer's information sharing benefits more from a higher level of the production learning effect when demand information is unclear, and information sharing benefits more from a lower level of the production learning effect when demand information is more accurate. In addition, in terms of profitability following information sharing, we ultimately discover that a unilateral payment contract renders the single cost reduction strategy superior to the single channel expansion strategy. The best incentive strategy to encourage retailer information sharing is to simultaneously implement cost reduction and channel expansion. Finally, we obtain some management insights that support supply chain parties in making decisions regarding the resolution of channel conflicts and the realization of information cooperation.
Intraoperative Acetabular Fracture
Authors: Hipfl Christian , Perka Carsten 
Published: January 2025

AbstractIntraoperative acetabular fracture is a rare complication in total hip arthroplasty. It occurs mainly as a result of impaction of a cementless press-fit cup. Risk factors include decreased bone quality, highly sclerotic bone, and a press-fit that was relatively too large. The timing of the diagnosis determines the therapeutic approach. Fractures detected intraoperatively should be treated with appropriate stabilisation. Postoperatively, the stability of the implants as well as the fracture pattern determine whether a conservative treatment is initially feasible. Most acetabular fractures diagnosed intraoperatively are to be treated with a multi-hole cup, with additional screws anchoring in the different acetabular regions. In cases of large posterior wall fragments or pelvic discontinuity, plate osteosynthesis of the posterior column is indicated. Alternatively, cup-cage reconstruction can be utilised. Especially in elderly patients, the therapeutic goal must be rapid mobilisation through adequate primary stability, in order to minimise the risk of complications, revision, and mortality.
A Rare Case of Cystic Angiomatosis Involving the Bones: Our Experience and Review of Literature
Authors: Dwivedi Priyatesh Chandra , Borde Chaitanya , Yasam Ramesh Venkata , Nagarkar Raj 
Published: January 2025

AbstractCystic angiomatosis (CA) is a rare, benign, multifocal disorder of mixed lesions (lytic, sclerotic) developed due to maldeveloped lymphatic and vascular systems. In majority of cases, it is identified fortuitously and mimicked as metastatic malignant lesions. In such cases, differential diagnosis followed by treatment is identified to be critical for stabilizing the disease and its prognosis. We reported a case of a 24-year-old female who presented to our center with complaints of lower back ache (∼4–6 weeks), intermittent pain in the abdomen, and occasional dyspnea on exertion. Imaging studies revealed mild lytic lesions and small-sized cysts in the spine, bones, and spleen. Investigations confirmed CA and follow-up treatment was given using zoledronic acid (4 mg/intravenous) every 3 months to stabilize the bone lesions. CA is a heterogeneous disease with unpredictable progression and uncertain treatment. So, it is highly recommended to disseminate research findings of all such rare cases to find any new pathophysiological findings and establish an effective treatment.
When does historical context matter? Explaining the emergence of competence-creating subsidiaries
Authors: Godley Andrew C. , Hamilton Shane , Joseph Marrisa 
Published: January 2025

AbstractDespite thorough attention to how context shapes subsidiary behavior, very little IB research has explored the dynamic impact of disruptive changes in historical context on organizational innovations in MNEs. Existing IB theory has robustly theorized the growth of competence-creating subsidiaries from the 1980s to the 2000s. However, our historical research demonstrates that this body of existing theory fails to explain an equally significant growth in subsidiaries with protean competence-creating characteristics from 1945 to 1970. We show that the introduction of the U.K. National Health Service in 1948 precipitated a major upgrade of research capabilities among a near majority of the population of subsidiaries in U.K. pharmaceuticals by 1970. Synthesizing from both IB and literature on historical methods, we analyze the impact of this disruptive transformation in context, identifying the specific mechanisms that produced the rapid growth in what we identify as proto-competence-creating subsidiaries. This occurred in response to a dramatically new context, in ways that differ from those predicted by current theoretical explanations, and led to an institutional innovation hitherto unknown to IB. The implications of this are significant in a contemporary moment of rapid institutional disruption, when existing conceptualizations of subsidiary behavior may increasingly fail to capture real-world dynamics.
The self in jeopardy: the curious absence of race in psychoanalytic inquiry
Authors: Esprey Yvette , Stevens Garth 
Published: January 2025

AbstractDrawing on a scan of psychoanalytic writing, this paper engages with the historical absence of race as a subject of enquiry within classical psychoanalytic thinking and practice. In considering that psychoanalysis has only recently begun to engage more intentionally with race in thinking and practice, we suggest that this engagement has historically been complicated, and remains complex, because it challenges foundational psychoanalytic tenets, whilst concomitantly provoking a jeopardy of the self of the analyst/therapist. The paper distills key conceptual issues that are contested when considering the relevance of the racialized societal landscape on the development of the psyche—in particular, the impact on conceptualizing the nature of the unconscious, and of transference and countertransference. In addition, we consider the question of analytic neutrality and the manner in which racial melancholia may manifest to generate vulnerabilities for the analyst/therapist, when race is central to the analytic encounter. The paper emerges from an assumption that the internal world is not quarantined from external social discourses, practices and structures, but rather that these are reciprocally implicated in the structuring of the psyche. We propose a psychoanalytic project that engages with the psychic imprint of the external world, and allows for the possibility that the resolution of racial entanglements may not be the therapeutic ideal, and that ongoing work with such ambivalences and contradictions may in fact be desirable.
Xiaosi ‘die laughing’ as a discourse marker
Authors: Chung Siaw-Fong , Yen Yu-Che 
Published: January 2025

Abstract
This study investigates the usage of 笑死
(xiaosi hereafter, ‘laugh-die; die laughing’) in Facebook posts retrieved during Taiwan’s level-3 COVID-19
alert period (5/15/2021–7/26/2021). The analysis of xiaosi revealed that it serves two major functions: (a) as
its literal meaning, ‘to laugh to death’ (die laughing), and (b) as a discourse marker. The use of this discourse-marker function
demonstrates that it has acquired a new pragmatic function in social media contexts beyond its literal meaning. Specifically,
xiaosi can express a speaker’s stance or provide an evaluative comment on the situation, thus introducing a
new conversational function distinct from its original meaning.
Pressure induced semimetal-to-metal transition and new structure of Ta2NiSe5 above 10 GPa
Authors: Gan Xiaolong , Zhang Han , Jin Shuoxue , Chen Dongliang , Guo Zhiying 
Published: January 2025

Abstract
Previous studies of the transition metal chalcogenide Ta2NiSe5 has identified two phase transitions occurring between 0–10 GPa, involving the excitonic insulator-to-semiconductor transition at 1 GPa and the semiconductor-to-semimetal transition at 3 GPa. However, there is still a lack of in-depth research on the changes in its physical properties changes above 10 GPa. In this study, Ta2NiSe5 were investigated under high-pressure conditions using high-pressure x-ray diffraction and high-pressure x-ray absorption experiments. During the experimental process, a novel phase transition from the semimetal to the metal phase was observed between 10–60 GPa, specifically between 10–14 GPa, and the structure of the new phase was determined to be P21/m through first-principles calculations. This transition mechanism is attributed to the sliding of the weakly coupled layers of Ta2NiSe5 within the a-c plane, leading to changes in the crystal lattice constants and symmetry. This research fills a gap in the understanding of Ta2NiSe5’s crystal structure under high pressure and contributes to the broader field of transition metal chalcogenides.
Chromopolarizability of charm-beauty quarkonium from $B_c(2S) \rightarrow B_c\pi\pi$ transition
Authors: Chen Yun-Hua , Li Zi-Wei 
Published: January 2025

Abstract
The chromopolarizability of a charm-beauty quarkonium characterizes its interaction with soft gluonic fields and can be probed through heavy quarkonium decays. Using the dispersion theory which considers the $\pi\pi$ final state interaction model-independently, we analyze the transition $B_c(2S) \rightarrow B_c\pi^+\pi^-$ and determine the chromopolarizability $\alpha_{B_c(2S) B_c}=(0.66\pm 0.25)$ GeV$^{-3}$ and the parameter $\kappa =-0.02\pm 0.13$.&#xD;Our results indicate that the transitional chromopolarizability of the $c\bar{b}$ state lies between the transitional chromopolarizabilities of the $c\bar{c}$ and $b\bar{b}$ states. These findings provide valuable insights into the interactions of charm-beauty quarkonium with light hadrons.
Accessing the stringy structure of proton in the framework of Color Glass Condensate
Authors: Xiang Wenchang , Cai Yanbing , Wang Mengliang , Zhou Dai-Cui 
Published: January 2025

Abstract
To investigate the possible geometric structure of the proton, an improved stringy proton model is constructed beyond the smallest distance approximation and treats the constituent (up and down) quarks initiated gluon tubes separately, where the constituent quarks are connected by gluon tubes which merge at the Fermat point of the quark triangle. The exclusive diffractive vector meson production process in electron-proton deep inelastic scattering is used to test the stringy structure of the proton. We calculate the coherent and incoherent differential cross sections of the exclusive diffractive $J/\Psi$ photoproduction in the framework of Color Glass Condensate. The results show that our calculations are in good agreement with HERA data. Especially, our results give a better description of the HERA data at small $t$ as compared to the ones from the hot spot model where the constituent quarks are uncorrelated distributed in the proton. Meanwhile, the radius of the proton resulting from the improved stringy proton model is coincident with the one from fitting to the data from GlueX Collaboration at Jefferson Lab, which indicates that the predictive power of the stringy proton model is significantly improved once it goes beyond the smallest distance approximation and treats the constituent quarks separately, instead of using the same profile for up and down quarks initiated gluon tubes. Moreover, we assume that the transverse shape of gluon tube satisfies Gaussian distribution, and explore the distribution width of the individual gluon tubes. We find an interesting result that the up quark initiated gluon tube seems to have larger distribution width than the down quark initiated gluon tube, which is favored by the HERA data.
New Yukawa-Corrected Casimir Wormholes in Curvature-Matter Coupled Gravitational Framework
Authors: Waheed Saira 
Published: January 2025

Abstract
In this article, our primary objective is to construct new wormhole solutions by involving&#xD;Yukawa-corrected form of Casimir energy density in a well-motivated gravitational theory that&#xD;allows the coupling of curvature and matter namely $\mathbb{F}(R,\mathcal{T})$ theory. To achieve this&#xD;goal, a wormhole geometry exhibiting the spherically symmetric nature is taken into account and anisotropic&#xD;fluid is assumed to be the background ordinary matter source. As a first case, we consider simple linear&#xD;$\mathbb{F}(R,\mathcal{T})$ theory by assuming $\mathbb{F}(R,\mathcal{T})=R+2\zeta\mathcal{T}$ with $\mathbb{L}_m=-\mathbb{P}$&#xD;(average pressure). As a second choice, we utilize the conformal symmetries of spherical symmetric geometry&#xD;for simplifying the resulting field equations and obtain corresponding analytical form of wormhole solution.&#xD;In both cases, the viability of proposed solutions is examined by checking the basic features of wormhole&#xD;shape model along with the validity of null energy constraints. Further, we study the volume integral&#xD;quantifier, exoticity factor, stability through TOV equation as well as adiabatic index, active gravitational&#xD;mass and complexity factor graphically. As a last case, we use a newly proposed wormhole shape function&#xD;to find the expressions of state variables and discuss the validity of energy bounds. We also explore the&#xD;significance of this wormhole shape model through different quantities graphically. In all scenarios,&#xD;it is found that the presented solutions are new, promising and viable.

Published: January 2025

Abstract
This article proposes a novel biosensor based on a five-semi-circular cladding tube hollow core antiresonant fiber (HC-ARF) with a frequency range of 0.5-2.8 THz, using Zeonex as the background material. The HC-ARF biosensor analyses various blood components, namely water, plasma, white blood cells (WBC), hemoglobin (HB), and red blood cells (RBC). We utilized COMSOL Multiphysics to perform the numerical analysis of the sensor model. For water, plasma, WBC, HB, and RBC, the proposed HC-ARF biosensor exhibits the highest sensitivity levels of 99.50%, 99.58%, 99.43%, 99.58%, and 99.46%, respectively. Furthermore, it demonstrates confinement loss (CL) and effective material loss (EML) of 1.3 × 10−3 dBcm−1 and 5.3 × 10−5 dBcm−1, respectively.

Abstract
Spin states in semiconductors provide exceptionally stable and noise-resistant environments for qubits, positioning them as optimal candidates for reliable quantum computing technologies. The proposal to use nuclear and electronic spins of donor atoms in silicon, introduced by Kane in 1998, sparked a new research field focused on the precise positioning of individual impurity atoms for quantum devices, utilising scanning tunnelling microscopy and ion implantation. This roadmap article reviews the advancements in the 25 years since Kane’s proposal, the current challenges, and the future directions in atomic-scale semiconductor device fabrication and measurement. It covers the quest to create a silicon-based quantum computer and expands to include diverse material systems and fabrication techniques, highlighting the potential for a broad range of semiconductor quantum technological applications. Key developments include phosphorus in silicon devices such as single-atom transistors, arrayed few-donor devices, one- and two-qubit gates, three-dimensional architectures, and the development of a toolbox for future quantum integrated circuits. The roadmap also explores new impurity species like arsenic and antimony for enhanced scalability and higher-dimensional spin systems, new chemistry for dopant precursors and lithographic resists, and the potential for germanium-based devices. Emerging methods, such as photon-based lithography and electron beam manipulation, are discussed for their disruptive potential. This roadmap charts the path toward scalable quantum computing and advanced semiconductor quantum technologies, emphasising the critical intersections of experiment, technological development, and theory.
Application of low-cost hydrokinetic technology for accelerating electricity access to rural areas in developing economies: field experiment in Kenya
Authors: Awandu Willis , Wiesemann Jens-Uwe , Lehmann Boris 
Published: January 2025

Abstract
This article presents the design, construction and field test of an experimental prototype of a low-cost hydrokinetic turbine technology made of local materials and e-waste components. The aim of this study is to investigate the performance of the turbine when subjected to field conditions in low flow velocity rivers. The research and development (R&D) involve the use of e-waste boat motor and locally available materials to develop a modular hydrokinetic turbine for generation of electricity using kinetic energy of rivers. A decommissioned boat motor with a 0.24 m diameter rotor is operated as a turbine. A shroud for flow acceleration was developed from 1.5 mm thick stainless-steel plates and a support structure constructed using angle lines. The field test results of the prototype generated about 11.543 ± 0.021 W and 37.129 ± 0.021 W or (equivalent of 0.011543 kWh and 0.037129 kWh) when operated at an approach flow velocity of 0.8 m s−1 and 1.2 m s−1 respectively. The wire to water ratio was determined instead of the Cp and the turbine achieved an overall wire to water efficiency of 0.99 and 0.95 respectively. This prototype technology can sustainably provide 24 h energy, sufficient to charge batteries in the rural areas and also provide opportunities within the community such as mobile charging points. An upscaled version of this low-cost technology can be adaptable in rural off-grid communities to enhance the access to electricity in developing countries.
