Published: January 2025

Light impinges on a camera's sensor as a collection of discrete quantized elements, or photons. An emerging class of devices, called single-photon sensors, offers the unique capability of detecting individual photons with high-timing precision. With the increasing accessibility of high-resolution single-photon sensors, we can now explore what computer vision would look like if we could operate on light, one photon at a time.

Determining the differential diagnosis of small scalp cysts identified on a fetus is difficult. In particular, many physicians have difficulty differentiating small meningoceles from small scalp cysts during the prenatal period. Volume contrast imaging increases contrast between tissues, thereby allowing an enhanced view of target structures. A 15 × 5 mm scalp cyst was identified on a fetus during a prenatal ultrasonography examination performed at 20 weeks of gestation. The cyst was not connected to the blood flow, and did not include the tissue of the brain parenchyma. Ventriculomegaly and other structural abnormalities were not observed. Based on these findings, we suspected a sinus pericranii or fetal epidermal cyst. The size of the fetal scalp cyst was stable, and the growth of the fetus remained normal until birth. The diagnosis of a small meningocele was confirmed postnatally, based on the results of a magnetic resonance imaging examination. Postnatal evaluation of offline volume contrast imaging of prenatal three‐dimensional ultrasound data at 22 weeks of gestation revealed a skull bone defect beneath the cyst. Volume contrast imaging can facilitate the prenatal diagnosis of small meningoceles by detecting bone defects on the fetal head.

Although the key aspects of genetic evolution and their clinical implications in clear-cell renal cell carcinoma (ccRCC) are well documented, how genetic features coevolve with the phenotype and tumor microenvironment (TME) remains elusive. Here, through joint genomic–transcriptomic analysis of 243 samples from 79 patients recruited to the TRACERx Renal study, we identify pervasive nongenetic intratumor heterogeneity, with over 40% not attributable to genetic alterations. By integrating tumor transcriptomes and phylogenetic structures, we observe convergent evolution to specific phenotypic traits, including cell proliferation, metabolic reprogramming, and overexpression of putative cGAS–STING repressors amid high aneuploidy. We also uncover a coevolution between the tumor and the T-cell repertoire, as well as a longitudinal shift in the TME from an antitumor to an immunosuppressive state, linked to the acquisition of recurrently late ccRCC drivers 9p loss and SETD2 mutations. Our study reveals clinically relevant and hitherto underappreciated nongenetic evolution patterns in ccRCC.

Significance:

Using joint genomic–transcriptomic analysis of 243 samples, we reveal recurrent patterns of nongenetic evolution in ccRCC not exclusively governed by genetic factors, including T-cell depletion, tumor T-cell receptor coevolution, potential cGAS–STING repression, and increased cell proliferation. These patterns can aid clinical management and guide novel treatment approaches.

Abstract
Virtual staining for digital pathology has great potential to enable spatial biology research, improve efficiency and reliability in the clinical workflow, as well as conserve tissue samples in a nondestructive manner. In this study, we demonstrate the feasibility of generating virtual stains for hematoxylin and eosin (H&E) and a multiplex immunofluorescence (mIF) immuno-oncology panel (DAPI, PanCK, PD-L1, CD3, and CD8) from autofluorescence (AF) images of unstained non–small cell lung cancer tissue by combining high-throughput hyperspectral fluorescence microscopy and machine learning. Using domain-specific computational methods, we evaluated the accuracy of virtual H&E staining for histologic subtyping and virtual mIF for cell segmentation–based measurements, including clinically relevant measurements such as tumor area, T-cell density, and PD-L1 expression (tumor proportion score and combined positive score). The virtual stains reproduce key morphologic features and protein biomarker expressions at both tissue and cell levels compared with real stains, enable the identification of key immune phenotypes important for immuno-oncology, and show moderate to good performance across various evaluation metrics. This study extends our previous work on virtual staining from AF in liver disease and prostate cancer, further demonstrating the generalizability of this deep learning technique to a different disease (lung cancer) and stain modality (mIF).
Significance:
We extend the capabilities of virtual staining from AF to a different disease and stain modality. Our work includes newly developed virtual stains for H&E and a multiplex immunofluorescence panel (DAPI, PanCK, PD-L1, CD3, and CD8) for non–small cell lung cancer, which reproduce the key features of real stains.

Published: January 2025

The present study aimed to validate an instrument for analyzing the motives for consuming eSports in Brazil. The instrument consisting of 11 dimensions was translated into Portuguese and then three judges performed an analysis of the items according to clarity and relevance, to calculate the Content Validity Coefficient. Then, a Confirmatory Factor Analysis allowed us to analyze the psychometric properties of the model, with a sample of 205 individuals. The review by the judges requested a change in the writing of 12 items and the content validity coefficients were above the cutoff point. Factor analysis indicated the need to remove the Drama motive and the final model presented a good fit to the data. The validation of the instrument will allow a better understanding of the reasons related to the consumption of eSports and help in making strategic decisions in this area.
O primeiro telégrafo em São Paulo
Authors: Cintra Jorge Pimentel
Published: January 2025

Estudamos o primeiro telégrafo que, a partir de 1822, estabelecia a comunicação entre Santos e São Paulo, numa época em que não havia eletricidade e, portanto, trata-se de um modelo dos primórdios em que a comunicação era feita através de sinais que se transmitiam visualmente a partir de pontos estratégicos no alto de morros. O modelo empregado era o de janelinhas, uma engenhosa invenção portuguesa de Francisco António Ciera. Por meio de documentos da época, mapas antigos e trabalhos de campo, conseguimos recuperar a efêmera história desse telégrafo (1822-1828) e determinar a localização precisa dos pontos em que foram instalados: Monte Serrat, Pico da Serra, Botujuru, Morro das Mercês, Morro Vermelho e Colégio.
Para que os alunos visualizem a história: o Museu Republicano “Convenção de Itu” e o ensino de história
Authors: Leite Marcelo Henrique
Published: January 2025

School visits are a significant part of museums’ history. To explore this theme, this article adopts a methodological approach that considers three levels of analysis: the museum, the educational actions, and the teaching applications. It applies the framework to the Republican Museum "Convention of Itu", located in the city of Itu, in the state of São Paulo, Brazil, mobilizing its foundation’s history and the school visits between 1987 and 2017. The documentary corpus is comprised by semi-structured interviews and the museum's institutional archive (including letters requesting school visits among other documents). The aim is twofold: to advance research on the intersection between (history) teachers and (history) museums and to stimulate and broaden the perspective on teaching practices.

Published: January 2025

As they exercise both administrative and operational functions using tactical equipment, Municipal Guards (MGs) are subjected to the development of postural changes and joint pain, which can be aggravated by the lack of physical activity. This cross-sectional study investigated the relationship between postural changes, perception of joint pain and the physical activity level, according to the sector in which MGs perform their duties. The MGs were submitted to a postural assessment using the SAPO Software, and a self-administered questionnaire: a) sociodemographic and professional characterization; b) V.A.S scale - pain; and c) short version of the IPAQ questionnaire - physical activity level. Most MGs were considered to be very active (53.3%), with postural changes of greater frequency and joint pain reported in the scapular and pelvic girdles, which may be related to the influence of the load exerted by the equipment and postures adopted during work.

Published: January 2025

O estudo objetivou comparar a qualidade motivacional de discentes de uma Instituição de Ensino Superior (IES) pública durante a paralisação das aulas, com alunos de uma IES privada, que substituiu as aulas presenciais por aulas remotas no período de isolamento social, resposta à pandemia causada pelo Coronavírus. Participaram do estudo 49 graduandos da IES pública e 57 graduandos do curso de Educação Física da IES privada. A Escala de Motivação Acadêmica foi aplicada por meio digital. Os resultados apontaram motivação mais autônoma dos estudantes da IES privada. Observou-se maior frequência de motivação extrínseca por regulação externa e por regulações sociais entre alunos da IES pública. Concluiu-se que o ensino remoto adotado na IES privada foi positivo, já que os alunos demonstraram capacidade de realizar atividades acadêmicas não apenas por pressão externa, apresentando boa qualidade motivacional. Ao contrário, a paralisação das aulas na IES pública indicou uma maior predisposição à desmotivação.

Published: January 2025

In recent decades, a series of studies have pointed out the benefits of motor learning in a condition of self-controlled practice. However, few studies have investigated the effects of this condition by manipulating the provision of demonstrations. The aim of this study was to investigate the effects of self-controlled demonstration on the learning of service skill under volleyball in children. The sample consisted of 24 volunteers, aged between 11 and 12 years, distributed in a group with demonstration self-control (n = 12), in which they were allowed to choose to view a video of an experienced model performing the motor skill before practice trials; and an externally controlled group (n = 12), which had the provision of demonstrations matched to the choices made by the self-control group. The study had three phases: baseline, acquisition and retention test performed 72 hours after the acquisition phase. The results revealed no difference in the accuracy of the service under volleyball in any phase of the study. Regarding the request for demonstrations, it was identified that the frequency in the 1st block of trials was significantly higher than in the 2nd, 3rd and 4th blocks. We concluded that the self-controlled demonstration does not benefit the learning of the service under volleyball in children.

We aimed to investigate the acute effects of a continuous cardiovascular exercise on retrieval and savings while learning a discrete motor skill. Forty participants, aged 18-35 years were randomly divided into 2 groups, Exercise Group (EG), which practiced an underarm dart-throwing task and performed cardiovascular exercise before the retention test, and Control Group (CG), which had the same practice conditions of EG without the exercise session. The groups were submitted to 14 blocks of 10 trials on 2 consecutive days. On day 1, there was an acquisition phase; on day 2, the first block was run the retention and the others for savings. We assessed the motor performance through absolute and variable errors. Our results demonstrated that cardiovascular exercise did not impact the accuracy and variability of the motor performance either on the retention test or relearning rate. We concluded that continuous cardiovascular exercise does not influence the retrieval and savings during discrete motor skill learning.

Published: January 2025

Este estudo objetivou comparar o desempenho físico, fisiológico e a ocupação espacial de jogadores sub-15 e sub-17 durante pequenos jogos 3vs3. Vinte e quatro atletas de futebol e dezoito atletas de futsal de nível regional foram selecionados para o estudo. Pequenos jogos 3vs.3 foram praticados em ambas as modalidades, com regras e tamanho do campo adaptados a partir do jogo formal. Dispositivos de GPS coletaram os dados físicos, fisiológicos e a ocupação espacial. Os dados foram comparados usando uma ANOVA two-way. Atletas de futebol apresentaram maior resposta física e fisiológica e a ocupação espacial foi similar entre as modalidades. Jogadores mais velhos apresentaram maior resposta física do que os mais jovens, sem diferenças na ocupação espacial. Contudo, diferenças relacionadas à idade foram observadas apenas nos atletas de futebol. Conclui-se que o contexto de cada modalidade induz a adaptações diferentes ao longo do processo de formação esportiva, com uma tendência de maiores respostas em atletas mais velhos e uma maior especialização entre os atletas de futebol.

Existen varias pruebas funcionales para evaluar el equilibrio dinámico en las personas mayores, pero la mayoría de ellas están indicadas para la población más frágil con el fin de evaluar el riesgo de caídas. Teniendo en cuenta el aumento del número de personas mayores que participan en programas de acondicionamiento físico y, en consecuencia, la mejora de sus capacidades físicas y habilidades motoras, es de gran importancia, tanto para fines científicos como clínicos, disponer de una prueba válida y fiable para evaluar el equilibrio dinámico de esta población. Los objetivos de este estudio fueron adaptar el instrumento y el protocolo del Y Balance Test (YBT) para mujeres mayores activas y determinar su fiabilidad entre sesiones. Cincuenta y una mujeres sanas (66,6 ± 5,3 años) se sometieron a una versión adaptada del YBT en la que se permitía que la extremidad activa volviera y tomara contacto con la base de apoyo antes de un nuevo intento. El intervalo entre la prueba y el nuevo intento osciló entre cinco y siete días. Los coeficientes de correlación intraclase (CCI) para todas las variables son superiores a 0,90, lo que indica una excelente fiabilidad test-retest entre sesiones. Los niveles de concordancia son buenos y pueden detectarse diferencias reales en las puntuaciones inferiores al 3,6% de la media. Además, el protocolo permitió completar la tarea en menos tiempo y sin miedo a caerse, lo que mejoró la eficacia de las sesiones de prueba. En conclusión, las adaptaciones propuestas al equipo y al protocolo, denominado «Y Balance Test-Aged» versión, produjeron resultados fiables para evaluar el equilibrio dinámico en mujeres mayores activas.
Paradigma e excepcionalidade no evento racial do Atlântico Verde
Authors: Pacheco Victor Augusto da Cruz
Published: January 2025

This article aims to reflect on how the ambiguous, anomalous, and complex processes of Irish history expose the dynamics of antiblackness as paradigmatic for the concept of “Human” and the exceptionality of the Irish experience. Based on the theoretical framework of black radical thought (SILVA, 2019; WILDERSON III, 2010, 2020) and Irish historiography (KENNY, 2006; O’NEILL; LLOYD, 2010; OHLMEYER, 2023), I will explore the Irish presence in the Atlantic, considering the ambiguity and complexity of the Irish as victims and agents of colonial projects in the Americas and Africa, as well as Frederick Douglass’s visit to Ireland in the nineteenth century. Following the term “racial event” proposed by Denise Ferreira da Silva (2019), I argue that the Green Atlantic demonstrates (1) the exceptionality of the Irish case for the experience of whiteness, (2) the ruses of the analogy between the black and Irish experiences and (3) the paradigmatic position of antiblackness for the project of forming Irish identity and its inscription in the “human family”.

This article proposes an ecocritical reading of the novel Bugônias (2022), by Daniel Galera.  To  this  end,  an updated  critical  contribution  was  mobilized  to  enable the analysis of the participation of different living beings in the narrative, highlighting metamorphosis as a manifestation  of  inter  and  intra-species  alliances.  The presentation of animals as agents and as capable of language enables readings of the  novel  that  move  away from  speciesism.  Furthermore,  the  journey  of  the character Chama is studied from the perspective of a coming-of-age story, altering some of the perspectives present in traditional romance novels. Finally, it is argued that the Organism also participates in this formative process, becoming a sympoetic system.
Crítica da (de)colonialidade em um ensaio: mestiçagem e antinegritude em Crítica da colonialidade em oito ensaios, de Rita Segato
Authors: Silva Camila Geovanna Alves da
Published: January 2025

Este artigo tem por objetivo analisar a instrumentalização da antinegritude como pressuposto ou condição para a proposta de ressignificação positiva da mestiçagem em três ensaios da antropóloga Rita Segato. Para tanto, mobilizo os estudos de Denise Ferreira da Silva (2018) e Frank B. Wilderson III (2021), pleiteando os conceitos de evento racial e afropessimismo para examinar os deslocamentos discursivos de Segato ao propor a inclusão do branco na categoria de mestiço em benefício da “raça geral” latino-americana. Em conclusão, defendo que a proposta de Segato mobiliza duas noções contraditórias de história e reitera a ideia de mutabilidade internacional das hierarquias raciais para isentar o papel do branco latino-americano na promoção e manutenção da antinegritude.
Entre o homem e o fantasma: Lídia à beira da cama, à beira do mundo. Acima, mulher do povo
Authors: Cristani Vanessa Didolich
Published: January 2025

O presente artigo propõe uma leitura crítica de Lídia Martins, personagem do romance O ano da morte de Ricardo Reis, de José Saramago, criada do Hotel Bragança, local em que Ricardo Reis, heterônimo de Fernando Pessoa, hospeda-se assim que chega a Lisboa. Mulher simples e do povo, subverte a imagem da musa Lídia etérea cunhada por Reis, e o traz à realidade cuja crueza eles não escapam. Ele, porque perde a capacidade de produzir raciocínio; ela porque simplesmente é mulher, e como tal, carrega os costumes preconceituosos produzidos historicamente e estão atrelados ao sistema vigente de Portugal. O trabalho utiliza a abordagem histórica realizada por Silvia Federici (2017) sobre a nascente da misoginia, atrelada ao catolicismo e ao capitalismo, conceito empregado durante o governo do ditador António de Oliveira Salazar, que o aplicava através de uma visão essencialista, onde à mulher cabiam as tarefas do cuidado com o lar, como vocação. À esta visão a pesquisa atém-se aos estudos de Pierre Bourdieu (2016), que a analisa como a naturalização da dominação masculina, advinda historicamente dos pensadores clássicos, detentores do saber. Ricardo Reis é discípulo desta epistemologia, e está embrenhado em labirintos, que se aludem à multiplicidade pessoana, da qual o autor tece em ironias. À brincadeira de Saramago abordar-se-á os pensamentos de Tzvetan Todorov (1980) para ilustrar o fantástico dentro do texto criado pelo autor português. Saramago nos convida a caminhar pelos labirintos de Lisboa onde todos os caminhos levam a Luís de Camões, reencontro com uma história que parece insolúvel em meio ao regime totalitário de Salazar. Enquanto todos são fantasmas, estão mortos e incapazes de pensar, Lídia é figura real, personificação do feminino, e que sobrevive por meio à sabedoria.
A enorme parábola contínua: a insensatez da realidade em Dashiell Hammett e Rubem Fonseca
Authors: Baldi Mateus
Published: January 2025

O artigo pretende ler os autores Dashiell Hammett e Rubem Fonseca a partir da “insensatez da realidade” presente em seus romances. Tomando por base a Parábola de Flitcraft, uma narrativa enxertada no romance O falcão maltês (1930), de Hammett, delineamos como os efeitos da primeira literatura noir se espraiaram até o brasileiro Rubem Fonseca e seu romance A grande arte (1983). Amparados pela noção de hospedagem formulada por Silviano Santiago (2023), aproximamos os dois romances para demonstrar como ambos lidaram com a representação da sociedade urbana em diferentes momentos do século XX.

Duas passantes na multidão: Cecília Meireles e dois poemas de Baudelaire
Authors: Barbosa Kátia Beatriz Leandro , Veras Eduardo Horta Nassif
Published: January 2025

This article proposes an approach between the poems "Lei do passante"and "Multidão", by Cecília Meireles, both from the book "Poemas escritos na Índia"(Poems Written in India), and "A uma passante"and Äs multidões", the first from "As flores do Mal"(The Flowers of Evil) and the second from "Pequenos poemas em prosa"(Small Prose Poems), by Charles Baudelaire. The comparative analysis starts from the importance of travel, wandering, and modernity for the poetry of both authors, while highlighting the differences, especially regarding each one's relationship with the outside world, the metropolis, and modern life in general. The dialoghe with the French poet, already noted by other researchers, reaffirms Meireles insertion into the tradition of modern poetry, even in a book dedicated to a culture and a society almost entirely different from the Western one. "Lei do passante and "Multidão"are therefore read from two perspectives: intertextuality with Baudelaire's poems and their position within the scope of the set of "Poemas escritos na Índia". Thus, "Lei do passante"is read as a programmatic poem, aimed at presenting the poetic and philosophical assumptions underlying Meireles'wandering in India.

Who Forgives Sins but God? None, One, or Many?
Authors: Henning Bruce
Published: January 2025

In the wider scope of Luke-Acts, the forgiveness of the paralyzed man (Luke 5:17–26) is similar to Matthew’s (9:1–8) not only in presenting Jesus as God’s agent of forgiveness but in including the disciples in this work as well. Three intratextual connections support this interpretation: the proclamation of forgiveness in Luke 4:18 as part of the Isaianic servant’s mission that is fulfilled by disciples elsewhere in Luke-Acts; the call of the fishermen (Luke 5:1–11) that establishes disciples as Jesus’ agents; and the healing in Acts 3–4 that parallels the episode, so that Peter’s miracle demonstrates that he too has authority, but only in Jesus’ name.
Learning from online hate speech and digital racism: From automated to diffractive methods in social media analysis

Published: January 2025

There has been a dramatic surge in uses of big data analytics and automated methods to detect and remove hate speech from social media, with these methods deployed both by platforms themselves and within academic research. At the same time, recent social scientific scholarship has accused social media data analytics of decontextualizing complex sociological issues and reducing them to linguistic problems that can be straightforwardly mapped and removed. Intervening in these debates, this article draws on findings from two interdisciplinary projects, spanning five years in total, which generated comparative datasets from Twitter (X). Focusing on three issues that we identified and negotiated in our own analysis – which we characterize as problems of context, classification and reproducibility – we build on existing critiques of automated methods, while also charting methodological pathways forward. Informed by theoretical debates in feminist science studies and STS, we set out a diffractive approach to engaging with large datasets from social media, which centralizes tensions rather than correlations between computational, quantitative and qualitative data.

This study systematically examines the effects of the modulus of Na2SiO3 on the compressive strength, hydration exothermic characteristics, pore structure, physical phase components, and microscopic morphology of slag concrete based on the fact that the modulus (mSiO2/mNa2O) of activated alkali has a significant impact on the properties of alkali-activated slag concrete (AASC). The results shown that as the modulus of Na2SiO3 increased, the compressive strength of alkali-activated slag concrete increased (11.31%-29.2%) and then dropped. The maximum compressive strength of AASC is found in AASC manufactured using Na2SiO3 with a modulus of 1.5. The cumulative heat release is greater for slag prepared with a modulus of 1, while the initial compressive strength is higher for slag prepared with a modulus of 2. In comparison to the AASC generated using Na2SiO3 with moduli of 1 and 2, the AASC prepared using Na2SiO3 with a modulus of 1.5 had the lowest porosity, a more optimized pore structure, the greatest C-(A)-S-H content, and the densest microstructure at the 28-day curing age, which is more conducive for the development of compressive strength of AASC.

Authors: Lu Fei , Li Congsun , Hu Pengfei , Hu Bin , Wu Haobo
Published: January 2025

Objective

To analyze the early- to mid-term clinical efficacy of personalized 3D-printed structural metal spacer technology in reconstructing massive bone defects during complex total knee arthroplasty (TKA) and revision surgery.

Methods

A single-center retrospective study was conducted on nine patients with severe bone defects who underwent TKA between 2018 and 2024. The general condition, surgical details, and clinical improvement of these patients were recorded and analyzed by clinical doctors.

Results

The average surgical duration was 183.9 minutes (range, 125–240 minutes), with intraoperative blood loss of 133.3 mL (range, 100–200 mL). The average hospital stay was 18.2 days (range, 10–42 days), and the follow-up duration was 13.2 months (range, 2–57 months). The preoperative average American Knee Society Score of 51.2 points (range, 15–74 points) improved significantly to 95.0 points (range, 81–106 points) at the last follow-up. No cases of vascular or nerve injury, infection, fracture, or prosthetic loosening were observed.

Conclusion

The precise manufacturing of customized spacers that seamlessly integrate with the patient’s skeletal structure ensures stability, adaptability, and improved surgical outcomes.
Cable Force Correction Method for Cable-Stayed Buckle-Cable Hoisting Incorporating Environmental and Construction Factors

Published: January 2025

Arch ribs in long-span, concrete-filled steel tube arch bridges are fabricated in segments and assembled on site via cable-stayed buckle-cable hoisting systems. The hoisting process involves a high risk, and monitoring systems have mainly been built to monitor the state of stress or deformation. However, instrumentation for stress monitoring, such as through-hole sensors, is expensive and has installation problems. Overreliance on instruments also leads to a disregard for the impact of environmental and construction factors on the actual state. To overcome these limitations, a cost-effective instrumentation system was developed, and a real-time monitoring program was implemented. In addition, a cable force correction method was proposed to increase the calculation accuracy by incorporating environmental and construction factors. The temperature difference is the controlling factor for the cable force; a value of 7.9°C yields a change in the cable force of 50.1 kN, which accounts for 21.1% of the total cable force. By incorporating the reverse friction at the saddles and the effect of temperature, a new correction equation for the cable force was proposed, in which the overall deviation between the measured results and the calculated results was reduced to 2%, providing a template for cable force evaluation in the engineering community.
Evaluation of Spin in Clinical Trials of Mesenchymal Stromal Cells for the Treatment of Knee Osteoarthritis: A Systematic Review
Authors: Woolley Katherine , Milan Nesa , Master Zubin , Feeley Brian T.
Published: January 2025

Background:

The regenerative potential of mesenchymal stromal cells (MSCs) has sparked interest in their use for knee osteoarthritis. Concurrently, there have been investigations on how data in scientific journals are reported and how they may influence readers’ interpretations, or “spin bias.” These studies are at risk for bias, given the limited number of patients and inconsistent blinding or controls. The risk of spin bias also complicates the interpretation, as results may be presented in a way that favors a particular outcome.

Purpose:

To quantify and characterize spin bias in clinical trials of MSCs for knee osteoarthritis.

Study Design:

Systematic review.

Methods:

PubMed and Embase searches were conducted using the terms “mesenchymal stem cells” or “MSCs” and “knee arthritis” or “osteoarthritis” and “therapy” or “treatment” or “regeneration.” Overall, 2 independent reviewers classified spin as high, moderate, or low and as 1 of 3 types: (1) emphasizing statistically significant results, (2) interpreting nonsignificant results as treatment effectiveness, and (3) claiming treatment benefits despite nonsignificant results. Journals were categorized as orthopaedic or nonorthopaedic. Descriptive statistics, the chi-square test, and the Fisher exact test were used to analyze the data, with alpha set at P < .05.

Results:

Among the 54 studies, spin was found in 80.0% of articles, with 14.5% having high, 25.5% moderate, and 40.0% low levels of spin. Type 1 was found in 54.5% of articles, type 2 in 18.2%, and type 3 in 29.1%. Spin was less frequently observed in the Methods section of articles compared with the abstract (17.52; P = .003). Reports on adipose-derived MSCs were associated with a higher frequency and level of spin compared with reports on MSCs from other sources (18.92; P = .026). There was no difference in the frequency of spin between orthopaedic and nonorthopaedic journals (0.48; P = .49) and no association with the impact factor (5.34; P = .07). There was no association between spin and financial disclosures (0.02; P = .577).

Conclusion:

Spin bias was present in most MSC-related trials for knee osteoarthritis, with a higher frequency among those that utilized adipose-derived MSCs. Understanding the prevalence and strategies of spin can mitigate any potential misinterpretations of study outcomes.
Geometric parameters optimization of tap via response surface methodology and nondominated sorting dung beetle optimization algorithm
Authors: Li Kunyu , Song Qinghua , Qin Jing , Zhang Zewen , Liu Zhanqiang
Published: January 2025

Taps are widely used in the thread machining system. However, excessive loads during the tapping process can increase tap wear, which can affect tap life. Therefore, effective methods need to be proposed to solve the problems of excessive load and severe wear during tap tapping. This articleproposes a geometric parameters (e.g. rake angle ( Ky), cone angle ( Kr), helix angle ( Kh), etc.) optimization method based on response surface methodology (RSM) and nondominated sorting dung beetle optimization algorithm for a tap, exemplified through the tapping process of 304 stainless steel. This method is based on axial force ( Fa) and torque ( T). Firstly, the finite element model for the tapping process of 304 stainless steel is established, and the orthogonal simulation is carried out. Secondly, predictive models of Fa and T are established according to the RSM. The interaction effects of geometric parameters on Fa and T are revealed. After that, the nondominated sorting dung beetle optimization algorithm is implemented for the optimization of Ky, Kr, and Kh. The TOPSIS evaluation model is introduced to evaluate the Pareto optimal solution. Finally, some verification experiments are finished. The optimized tap shows a reduction in average axial force by 44.69 N and a decrease in average torque by 2.67 N·m. Under the same conditions, the flank wear width is reduced by 15.71%. The optimization method of tap geometry parameters in this paper is proposed based on finite element simulation and intelligent optimization algorithm. This method can provide technical guidance for the optimization of tool geometric parameters.

Published: January 2025

This paper presents an adaptive super-twisting fast terminal based on disturbance observer sliding mode control method for the attitude tracking of a quadrotor unmanned aerial vehicle in the presence of mismatched disturbances. The attitude tracking controller is formulated based on the introduced adaptive super-twisting technique. The utilization of dynamically adaptive gains in the controllers enhances the system’s robustness while reducing chattering effects. Additionally, a non-singular fast terminal sliding surface based on finite-time disturbance observer is defined. This approach effectively addresses the issue of mismatched disturbances while accelerating the convergence of tracking error. The stability analysis of the closed-loop system is established employing Lyapunov function. Finally, the effectiveness and success of the proposed method are validated through simulation and experimental results, with further comparisons to other techniques in terms of tracking performance and robustness.
Robust multivariable PID controller design for MIMO second order systems: A linear matrix inequality approach
Authors: Gontijo Danielle , Araújo José M , Souza Fernando O
Published: January 2025

This paper presents new linear-quadratic-regulator-based multivariable PID controller design conditions for MIMO uncertain second-order systems. The gain matrices of the multivariable PID controller are computed by solving an LMI problem which minimizes a cost function consisting of the expectation of the sum of quadratic forms relating the system states and control effort. The linear-quadratic-regulator-based design is much more intuitive to tuning than the eigenvalue assignment within a desired set or region for placement, in which a balance between the state trajectories and control energy is pursued through the tuning parameters. The proposed design methodology was tested on an experimental platform consisting of a mobile inverted pendulum robot, an underactuated and challenging control problem to ensure stability and performance. The obtained results support the theoretical findings.
