Published: October 2022

Physical processes that occur within porous materials have wide-ranging applications including - but not limited to - carbon sequestration, battery technology, membranes, oil and gas, geothermal energy, nuclear waste disposal, water resource management. The equations that describe these physical processes have been studied extensively; however, approximating them numerically requires immense computational resources due to the complex behavior that arises from the geometrically-intricate solid boundary conditions in porous materials. Here, we introduce a new dataset of unprecedented scale and breadth, DRP-372: a catalog of 3D geometries, simulation results, and structural properties of samples hosted on the Digital Rocks Portal. The dataset includes 1736 flow and electrical simulation results on 217 samples, which required more than 500 core years of computation. This data can be used for many purposes, such as constructing empirical models, validating new simulation codes, and developing machine learning algorithms that closely match the extensive purely-physical simulation. This article offers a detailed description of the contents of the dataset including the data collection, simulation schemes, and data validation.

Surgical trauma in those under a prolonged use of bisphosphonates, can lead to mediation-related osteonecrosis of the jaw (MRONJ). This study aimed to evaluate the preventive therapies for MRONJ. Following four cycles of zoledronic acid administration, Wistar rats had their molar extracted, and were organized into nine treatment groups: negative control group (NCG), treated with saline solution and blood-clot in the alveolus; positive control group (PCG), with blood-clot in the alveolus; BG, β-tricalcium phosphate-based biomaterial; DG, 10% doxycycline gel; aG, antimicrobial photodynamic therapy; and DBG, aBG, aDG, and aDBG, using combination therapy. After 28 days, the lowest bone volume (BV/TV) was reported in PCG (42.17% ± 2.65), and the highest in aDBG (69.85% ± 6.25) (p < 0.05). The higher values of daily mineral apposition rate were recorded in aDBG (2.64 ± 0.48) and DBG (2.30 ± 0.37) (p < 0.001). Moreover, aDBG presented with the highest neoformed bone area (82.44% ± 2.69) (p < 0.05). Non-vital bone was reported only in the PCG (37.94 ± 18.70%). Owing to the key role of the biomaterial, the combination approach (aDBG) was the most effective in preventing MRONJ following tooth extraction.
Large waves and navigation hazards of the Eastern Mediterranean Sea
Authors: Knobler Sagi , Liberzon Dan , Fedele Francesco
Published: October 2022

We present a statistical analysis of deep-water buoy measurements of large waves generated during two major storms of the Eastern Mediterranean in 2017 and 2018, respectively. The largest waves observed do display similar characteristics to those of the Draupner, Andrea, and El Faro rogue waves in that second order bound nonlinearities enhance the linear dispersive focusing of extreme waves. We also present a novel analysis of waves in space-time to predict potential risks posed by such large waves to navigation. In particular, we consider the scenario of two types of vessels of the Israeli Navy fleet navigating during the most intense stages of the two storms considered here and provide predictions for the largest waves likely to be encountered.
The distribution of initial estimates moderates the effect of social influence on the wisdom of the crowd

Published: October 2022

Whether, and under what conditions, groups exhibit “crowd wisdom” has been a major focus of research across the social and computational sciences. Much of this work has focused on the role of social influence in promoting the wisdom of the crowd versus leading the crowd astray and has resulted in conflicting conclusions about how social network structure determines the impact of social influence. Here, we demonstrate that it is not enough to consider the network structure in isolation. Using theoretical analysis, numerical simulation, and reanalysis of four experimental datasets (totaling 2885 human subjects), we find that the wisdom of crowds critically depends on the interaction between (i) the centralization of the social influence network and (ii) the distribution of the initial individual estimates. By adopting a framework that integrates both the structure of the social influence and the distribution of the initial estimates, we bring previously conflicting results under one theoretical framework and clarify the effects of social influence on the wisdom of crowds.

Published: October 2022

Effective mitigation of the impacts of invasive ship rats (Rattus rattus) requires a good understanding of their ecology, but this knowledge is very sparse for urban and peri-urban areas. We radiomarked ship rats in Wellington, New Zealand, to estimate detection parameters (σ, ε0, θ, and g0) that describe the process of an animal encountering a device (bait stations, chew cards and WaxTags) from a distance, and then approaching it and deciding whether to interact with it. We used this information in simulation models to estimate optimal device spacing for eradicating ship rats from Wellington, and for confirming eradication. Mean σ was 25.37 m (SD = 11.63), which equates to a circular home range of 1.21 ha. The mean nightly probability of an individual encountering a device at its home range center (ε0) was 0.38 (SD = 0.11), whereas the probability of interacting with the encountered device (θ) was 0.34 (SD = 0.12). The derived mean nightly probability of an individual interacting with a device at its home range center (g0) was 0.13 (SD = 0.08). Importantly, σ and g0 are intrinsically linked through a negative relationship, thus g0 should be derived from σ using a predictive model including individual variability. Simulations using this approach showed that bait stations deployed for about 500 days using a 25 m × 25 m grid consistently achieved eradication, and that a surveillance network of 3.25 chew cards ha−1 or 3.75 WaxTags ha−1 active for 14 nights would be required to confidently declare eradication. This density could be halved if the surveillance network was deployed for 28 nights or if the prior confidence in eradication was high (0.85). These recommendations take no account of differences in detection parameters between habitats. Therefore, if surveillance suggests that individuals are not encountering devices in certain habitats, device density should be adaptively revised. This approach applies to initiatives globally that aim to optimise eradication with limited funding.
An ultra-small nine-color spectrometer with a two-layer biparted ten-dichroic-mirror array and an image sensor
Authors: Anazawa Takashi , Yamamoto Shuhei , Inaba Ryoji
Published: October 2022

An ultra-small (54 × 58 × 8.5 mm) and large aperture (1 × 7 mm) nine-color spectrometer—using an array of ten dichroic mirrors “biparted” as two layers—was developed and used for snapshot spectral imaging. Incident-light flux with a cross section smaller than the aperture size is split into nine color fluxes with 20-nm-width contiguous wavelength bands and central wavelengths of 530, 550, 570, 590, 610, 630, 650, 670, and 690 nm. Images of the nine color fluxes are simultaneously and efficiently measured by an image sensor. Unlike a conventional dichroic-mirror array, the developed dichroic-mirror array has a unique biparted configuration that not only increases the number of colors that can be measured simultaneously but also improves the image resolution of each color flux. The developed nine-color spectrometer was used for four-capillary-array electrophoresis. Eight dyes concurrently migrating in each capillary were simultaneously quantified by nine-color laser-induced fluorescence detection. Since the nine-color spectrometer is not only ultra-small and inexpensive but also has high light throughput and sufficient spectral resolution for most spectral-imaging applications, it has the potential to be widely used in various fields.
The use of thermal imaging for monitoring the training progress of professional male sweep rowers
Authors: Straburzyńska-Lupa Anna , Korman Paweł , Śliwicka Ewa , Kryściak Jakub , Ogurkowska Małgorzata Barbara
Published: October 2022

This study assesses the thermal profile of the skin in highly trained rowers and investigates the relationship between resting skin temperature (Ts) and the muscle peak torque (PT) measured in statics at the beginning (autumn) and the end (spring) of the preparatory period. Ten professional male sweep rowers, members of the Polish national rowing team, were investigated. A thermal imaging camera was used to analyze the Ts. The PT of the muscles involved in the rowing cycle were measured isometrically. No significant temperature asymmetries were found, except in front of arms after exercise in the spring (p = 0.0228). In contrast, the PT test in the autumn confirmed the significant asymmetry of the knee joint extensors (p = 0.0192). In spring compared to autumn, Ts in many areas of the body were slightly higher, as was PT of underlying muscles. Significant correlations between resting Ts and PT of the underlying muscles were found. Thermal imaging makes it possible to observe changes in skin temperature and symmetry before and after exercise. At this stage, it does not appear to be a method that, without supporting of other methods such as those assessing muscle function, will allow monitoring of training progress.

Stent-grafts composed of expanded polytetrafluoroethylene (e-PTFE), polyethylene terephthalate (PET) and polyurethane (PU) are characterized by poor endothelialization, high modulus, and low compliance, leading to thrombosis and intimal hyperplasia. A composite synthetic/natural matrix is considered a promising alternative to conventional synthetic stent-grafts. This study aimed to investigate the efficacy of thermoplastic polyurethane (TPU) and gelatin (GL) blended nanofibers (NFs) covered stent-graft in the porcine iliac artery. Twelve pigs were randomly sacrificed 7 days (n = 6) and 28 days (n = 6) after stent-graft placement. The thrombogenicity score at 28 days was significantly increased compared at 7 days (p < 0.001). The thickness of neointimal hyperplasia, degree of inflammatory cell infiltration, and degree of collagen deposition were significantly higher at 28 days than at 7 days (all p < 0.001). The TPU and GL blended NFs-covered stent-grafts successfully maintained the patency for 28 days in the porcine iliac artery. Although thrombosis with neointimal tissue were observed, no subsequent occlusion of the stent-graft was noted until the end of the study. Composite synthetic/natural matrix-covered stent-grafts may be promising for prolonging stent-graft patency.

Wearable sensors have seen remarkable recent technological developments, and their role in healthcare is expected to expand. Specifically, monitoring tissue circulation in patients who have undergone reconstructive surgery is critical because blood flow deficiencies must be rescued within hours or the transplant will fail due to thrombosis/haematoma within the artery or vein. We design a wearable, wireless, continuous, multipoint sensor to monitor tissue circulation. The system measures pulse waves, skin colour, and tissue temperature to reproduce physician assessment. Data are analysed in real time for patient risk using an algorithm. This multicentre clinical trial involved 73 patients who underwent transplant surgery and had their tissue circulation monitored until postoperative day 7. Herein, we show that the overall agreement rate between physician and sensor findings is 99.2%. In addition, the patient questionnaire results indicate that the device is easy to wear. The sensor demonstrates non-invasive, real-time, continuous, multi-point, wireless, and reliable monitoring for postoperative care. This wearable system can improve the success rate of reconstructive surgeries.

Published: October 2022

Tuberculosis (TB) caused byMycobacterium tuberculosis(Mtb) is the second-deadliest infectious disease worldwide. Emerging evidence shows that the elongation factor EF-Tu could be an excellent target for treating Mtb infection. Here, we report the crystal structures of Mtb EF-Tu•EF-Ts and EF-Tu•GDP complexes, showing the molecular basis of EF-Tu’s representative recycling and inactive forms in protein translation. Mtb EF-Tu binds with EF-Ts at a 1:1 ratio in solution and crystal packing. Mutation and SAXS analysis show that EF-Ts residues Arg13, Asn82, and His149 are indispensable for the EF-Tu/EF-Ts complex formation. The GDP binding pocket of EF-Tu dramatically changes conformations upon binding with EF-Ts, sharing a similar GDP-exchange mechanism inE. coliandT. ther. Also, the FDA-approved drug Osimertinib inhibits the growth ofM. smegmatis, H37Ra, andM. bovisBCG strains by directly binding with EF-Tu. Thus, our work reveals the structural basis of Mtb EF-Tu in polypeptide synthesis and may provide a promising candidate for TB treatment.
GAB functions as a bioenergetic and signalling gatekeeper to control T cell inflammation

Published: October 2022

γ-Aminobutyrate (GAB), the biochemical form of (GABA) γ-aminobutyric acid, participates in shaping physiological processes, including the immune response. How GAB metabolism is controlled to mediate such functions remains elusive. Here we show that GAB is one of the most abundant metabolites in CD4+ T helper 17 (TH17) and induced T regulatory (iTreg) cells. GAB functions as a bioenergetic and signalling gatekeeper by reciprocally controlling pro-inflammatory TH17 cell and anti-inflammatory iTreg cell differentiation through distinct mechanisms. 4-Aminobutyrate aminotransferase (ABAT) funnels GAB into the tricarboxylic acid (TCA) cycle to maximize carbon allocation in promoting TH17 cell differentiation. By contrast, the absence of ABAT activity in iTreg cells enables GAB to be exported to the extracellular environment where it acts as an autocrine signalling metabolite that promotes iTreg cell differentiation. Accordingly, ablation of ABAT activity in T cells protects against experimental autoimmune encephalomyelitis (EAE) progression. Conversely, ablation of GABAA receptor in T cells worsens EAE. Our results suggest that the cell-autonomous control of GAB on CD4+ T cells is bimodal and consists of the sequential action of two processes, ABAT-dependent mitochondrial anaplerosis and the receptor-dependent signalling response, both of which are required for T cell-mediated inflammation.
Dense non-aqueous phase liquid chlorinated contaminant detected far from the source release area in an aquifer

Published: October 2022

Here we confirm migration of chlorinated solvents tetrachloroethene and trichloroethene, and co-disposed elemental mercury as dense non-aqueous phase liquid in an aquifer at a scale larger than previously documented in the literature, over 650 m from original surface discharge. This finding enhances the conceptual model explaining extensive contaminated plume persistence by adding structurally controlled dense non-aqueous phase liquid to known mechanisms such as source dissolution and matrix back-diffusion. Following injections of oxidants at a depth greater than 50 m, which effectively destroyed dissolved chlorinated contaminants during a groundwater remediation pilot test in South Carolina, we measured excess chloride higher than attributable to pre-test dissolved concentrations of chlorinated contaminants, and oxidative releases of mercury, which is an opportunistic tracer of non-aqueous phase solvent transport when in its elemental form. The results suggest potentially targeted destruction strategies in disconnected non-aqueous phase liquid accumulation areas may reduce remediation timeframe and support cleanup of sites previously considered technically impracticable.

Published: October 2022

The glaciological significance of ice shelves is relatively well established for the stability of modern ice sheets of Antarctica. Past ice shelves of the Arctic, however, are poorly documented while their role for the stability of former ice sheets remains mostly unknown. Here we present swath bathymetry data and seismostratigraphic profiles that reveal a large moraine system extending along the continental slope off Baffin Island, demonstrating that a 500-m thick ice shelf covered northern Baffin Bay during the last glacial episode. We suggest that this ice shelf had a profound impact on the stability of a series of major ice streams that drained the interior of the Laurentide, Innuitian and Greenland ice sheets. Climate warming and global sea-level rise in the early stage of deglaciation possibly contributed to a large-scale break-up of the ice shelf, which led to the destabilisation and reorganisation of tributary ice streams from these three ice sheets.

Published: October 2022

Conductive hydrogels that are highly elastic, fatigue resistant and environmentally adaptive are promising materials in the fields of wearable electronics, bioelectronics and soft robotics. However, these materials are challenging to develop, especially for use in harsh environments including organic solvents and extreme temperatures. Here we report a simple method for the fabrication of highly compressible and fatigue-resistant conductive hydrogels with reinforced-concrete-type constituents and high-tortuosity interconnected cellular architecture through a self-assembly and two-stage in situ polymerization process. The obtained composites exhibit excellent mechanical compressibility with negligible residual strain at 50% strain for >104 cyclic loadings both in air and water. Due to the structure-favoured anisotropic response to tensile deformations coupled with elastic recovery, the hydrogel is endowed with sensing dimensions which allow the direction and velocity of movement on the sensor surface to be distinguished. In addition, by interpenetrating with an oleophilic polymer network, highly elastic and adaptive organohydrogels are developed with outstanding sensing performance in a wide variety of organic solvents and cryogenic temperatures. These materials may therefore be suitable for use in flexible and wearable devices in harsh environments.

Developmental Changes in the Perception of Vocal Loudness and Voice Quality in 3- to 6-Year-Old Children
Authors: Feinstein Hagar , Abbott Katherine Verdolini , Morini Giovanna
Published: October 2022

Purpose:

The study's primary aim was to investigate developmental changes in the perception of vocal loudness and voice quality in children 3–6 years of age. A second aim was to evaluate a testing procedure—the intermodal preferential looking paradigm (IPLP)—for the study of voice perception in young children.

Method:

Participants were categorized in two age groups: 3- to 4-year-olds and 5- to 6-year-olds. Children were tested remotely via a Zoom appointment and completed two perceptual tasks: (a) voice discrimination and (b) voice identification. Each task consisted of two tests: a vocal loudness test and a voice quality test.

Results:

Children in the 5- to 6-year-old group were significantly more accurate than children in the 3- to 4-year-old group in discriminating and identifying differences between voices for both loudness and voice quality. The IPLP, used in the identification task, was found to successfully detect differences between the age groups for overall accuracy and for most of the sublevels of vocal loudness and voice quality.

Conclusions:

Results suggest that children's ability to discriminate and identify differences in vocal loudness and voice quality improves with age. Findings also support the use of the IPLP as a useful tool to study voice perception in young children.
Leveraging hierarchical semantic‐emotional memory in emotional conversation generation
Authors: Yang Min , Wang Zhenwei , Xu Qiancheng , Li Chengming , Xu Ruifeng
Published: October 2022

Handling emotions in human‐computer dialogues has emerged as a challenging task which requires artificial intelligence systems to generate emotional responses by jointly perceiving the emotion involved in the input posts and incorporating it into the generation of semantically coherent and emotionally reasonable responses. However, most previous works generate emotional responses solely from input posts, which do not take full advantage of the training corpus and suffer from generating generic responses. In this study, we introduce a hierarchical semantic‐emotional memory module for emotional conversation generation (called HSEMEC), which can learn abstract semantic conversation patterns and emotional information from the large training corpus. The learnt semantic and emotional knowledge helps to enrich the post representation and assist the emotional conversation generation. Comprehensive experiments on a large real‐world conversation corpus show that HSEMEC can outperform the strong baselines on both automatic and manual evaluation. For reproducibility, we release the code and data publicly at: https://github.com/siat‐nlp/HSEMEC‐code‐data.
Design of frequency‐selective rasorber with multiple bands
Authors: Xing Qijun , Yan Yuchen , Wu Weiwei , Yuan Naichang
Published: October 2022

In this letter, a novel dual‐polarized frequency selective rasorber (FSR) with multiple absorption bands and multiple transmission bands is presented. The proposed FSR consists of a lossy layer and a lossless multi‐bandpass frequency selective surface (FSS) layer, which are isolated by an air spacer. In the lossy layer, three parallel resonances can be generated by introducing rectangular spiral resonators on cross metal lines loaded with resistors. In order to achieve the same transmission frequency band as the top lossy layer, three square slots are designed at the bottom FSS layer. For demonstration, the proposed FSR is simulated, manufactured, and measured, and the measurement results are consistent with the simulation results.
Improved bandwidth and radiation efficiency of series‐fed patch array using cascaded inset‐fed mechanism
Authors: Yi Hao , Mu Yajie , Han Jiaqi , Li Long
Published: October 2022

In this letter, a novel design approach of low‐sidelobe series‐fed patch antenna array is proposed which has enhanced bandwidth and radiation efficiency. It is based on the fact that the out‐to‐input voltage amplitude ratio of an inset‐fed patch antenna element could be manipulated by changing the insert depth of the output microstrip line. Thus, by utilizing a cascaded inset‐fed mechanism, the series‐fed patch antenna array achieves voltage amplitude tapering for desired sidelobe suppression. The step‐down transformer model and the cascaded step‐down transformer model are presented to reveal the design approach as the equivalent circuit characterization of the antenna element. As a proof‐of‐concept, a 12‐element series‐fed patch antenna array operating 24 GHz with a 20 dB sidelobe level (SLL) is designed, simulated, and prototyped. It could be found that, in contrast to the conventional width‐tapering patch antenna array, the proposed design achieves an impedance bandwidth broadening, from 1.7% to 2.5%, and a radiation efficiency improvement of 7% meanwhile.
A novel distance protection scheme using single‐ended transient voltage based on generalized S transform
Authors: Li Yifan , Sun Peng , Li Hui , Huang Shaofeng , Wu Haifeng
Published: October 2022

Concerning the distance protection steady‐state over‐reach or under‐reach caused by the transition resistance, a novel distance protection scheme based on transient information is proposed. First, multiple fault features are extracted using the Generalized Stockwell Transform (GST), and a criterion for identifying low‐resistance and high‐resistance ground faults is constructed. Then, a GST coefficient matrix is established for the single‐ended transient voltage of the line, the attenuation coefficient and delay coefficient are derived by the least‐squares method and the beat phenomenon, and the transition resistance is calculated. On this basis, adjust the operation boundary in the +R axis direction of the operation zone according to the transition resistance value. Finally, test results on real‐time digital simulation system (RTDS) demonstrate that the protection scheme operates reliably in different fault cases and is highly immune to fault resistance. Compared with the traditional distance protection scheme, this scheme performs better when the transition resistance is large.

Respecto a las fracturas distales, representan un tercio de todas las fracturas del húmero en población adulta. Por lo general, se presentan en una distribución bimodal que afecta a hombres jóvenes o a mujeres ancianas. En este artículo, reportamos un caso clínico poco frecuente de luxación de codo izquierdo complicada, producto de fractura del húmero distal, en una mujer de 64 años. La lesión comprende una luxación posterolateral de codo izquierdo complicada con fractura articular parcial (compromiso del cóndilo y de la tróclea humeral externa), sagital, multifragmentaria, de húmero distal que requirió tres intervenciones quirúrgicas y terapia de rehabilitación por seis meses que finalizaron en recuperación funcional de la estabilidad de la articulación del codo. El caso reportado es particular debido a la individualidad del paciente con sus comorbilidades, el mecanismo de producción de la luxofractura, el abordaje quirúrgico, y el éxito del tratamiento instaurado. Sin embargo, este éxito terapéutico debe ser confirmado en series de casos.

Authors: Mendez Manuel , López Francisco
Published: October 2022

Las lesiones graves de los dedos con pérdida de sustancia y exposición de estructuras nobles constituyen un desafío para evitar la amputación. Estas situaciones han impulsado el desarrollo de un gran número de colgajos axiales, locales, con el fin de salvar el dígito. Los colgajos libres, tomados a medida, también han sido descritos para dar coberturas adecuadas y de buena calidad. Se presenta el caso de un paciente con lesión grave de dedo anular con exposición ósea y daño tendíneo, con una pérdida de cobertura de 4 × 4 cm. El paciente fue sometido a una reconstrucción con un colgajo libre del pie, tomando como eje vascular la primera arteria intermetatarsiana. El paciente conservó su dedo con una movilidad a expensas de la articulación interfalángica proximal (IFP), con una piel de buena calidad, pinza firme y sin dolor. La zona dadora no presentó complicaciones. En manos de un equipo entrenado, con indicación adecuada, estos colgajos logran un buen resultado estético y funcional.

Objetivo Avaliar uma proposta de processo de impressão tridimensional (3D) de um biomodelo preparado com o auxílio da tecnologia de modelagem por deposição de material fundido (fused deposition modeling, FDM, em inglês) a partir de imagens de tomografia computadorizada (TC) de um indivíduo com pseudartrose de fratura coronal do côndilo femoral (fratura de Hoffa).

Materiais e Métodos Para tanto, utilizamos imagens de TC, que permitem estudar a reconstrução volumétrica 3D do modelo anatômico, além da arquitetura e geometria óssea de sítios de anatomia complexa, como as articulações. Também permite o planejamento cirúrgico virtual (PCV) em um programa de desenho assistido por computador (computer-aided design, CAD, em inglês). Essa tecnologia possibilita a impressão de modelos anatômicos em escala real que podem ser utilizados em simulações cirúrgicas para o treinamento e a escolha do melhor posicionamento do implante de acordo com o PCV. Na avaliação radiográfica da osteossíntese da pseudartrose de Hoffa, verificou-se a posição do implante no modelo anatômico impresso em 3D e no joelho do paciente.

Resultados O modelo anatômico impresso em 3D apresentou características geométricas e morfológicas semelhantes às do osso real. O posicionamento dos implantes em relação à linha de pseudartrose e pontos anatômicos foram bastante precisos na comparação do joelho do paciente com o modelo anatômico impresso em 3D.

Conclusão A utilização do modelo anatômico virtual e do modelo anatômico impresso em 3D com a tecnologia de manufatura aditiva (MA) foi eficaz e auxiliou o planejamento e a realização do tratamento cirúrgico da pseudartrose da fratura de Hoffa. Desta forma, foi bastante preciso na reprodutibilidade do planejamento cirúrgico tanto virtual quanto no modelo anatômico impresso em 3D.

Objetivo Subrayar la importancia del diagnóstico detallado del dolor y realizar autocrítica por la tardanza diagnóstica de una cervicalgia mecánica.

Material y Métodos Se presenta una paciente con dolor súbito en el cuello, con radiografías y exploración normales. La resonancia magnética (RM) resultó aparentemente anodina y se trató como cervicalgia mecánica. Tras varias consultas con el Servicio de Urgencias, se realizó una radiografía que informó de anomalía entre las primeras vértebras y se amplió con una tomografía computarizada (TC) que reveló fractura de odontoides y destrucción de la segunda cervical de origen metastásico.

Resultados La paciente fue tratada con radioterapia más collarín cervical y varios ciclos de quimioterapia, y falleció a los dos años.

Discusión Los cánceres que más frecuentemente metastatizan en la columna vertebral son los de mama, pulmón y próstata, siendo las localizaciones más frecuentes la torácica (70%), la lumbar (20%) y, por último, la cervical (10%). Cuando el tumor se descubre como metástasis, como en nuestro caso, estos pacientes tienen una alta tasa de mortalidad. Según nuestro conocimiento, en la literatura hay pocos casos descritos de neoplasias descubiertas como fractura patológica de odontoides.

Conclusión El dolor cervical no mecánico debido a una metástasis en odontoides, a consecuencia de una neoplasia de pulmón no diagnosticada, es un caso raro en la literatura y de complejo diagnóstico, en que una historia clínica detallada de la evolución del dolor y la presencia de signos de alarma son de vital importancia para su sospecha y rápido diagnóstico, mediante técnicas como la RM.
Air-in-liquid compound drop impact onto a pool
Authors: Wang Lei , Thoraval Marie-Jean
Published: October 2022

We investigate numerically the dynamics of a drop containing a bubble impacting onto a pool of the same liquid. We show that the bubble can be engulfed into the pool after impact only for a limited range of impact velocities and bubble sizes. Below a critical Weber number, the compound drop bounces from the surface. By contrast, above a second threshold in Weber number, the bubble bursts during impact. Depending on the bubble size, we identify two different mechanisms responsible for this higher impact velocity threshold, with central bursting at lower bubble sizes, or dimple bursting at larger bubble sizes. We then characterize and model the dynamics of the cavity, to finally provide an overview of the mechanisms affecting the bubble stability in the liquid.
Characterization of SPIDER beam optics in volume operations with visible cameras
Authors: Agostini M. , Ugoletti M. , Pimazzoni A.
Published: October 2022

SPIDER (Source for Production of Ion of Deuterium Extracted from RF plasma) is the full-size prototype of the negative ion source for future ITER neutral beam injectors. With a maximum acceleration voltage of 100 kV, a negative ion beam is extracted and accelerated, and different diagnostics are developed to characterize the performance, shape, and deflection of the beam as well as the width of the beamlets. In particular, the optics of the accelerated beam is studied with a set of 15 cameras installed all around the beam, and they measure the visible emission; the spatial profile of the emission gives an estimate of the beamlets that compose the beam and also information about its optics. In this paper, experiments performed in volume operation (without cesium) are analyzed, studying the role of the extraction and acceleration voltages, polarization of plasma grid and bias plate, and magnetic filter field. It is shown how the width of the beam is not spatially uniform. Two types of non-uniformity are pointed out: a top/bottom asymmetry at large spatial scale and a smaller one at the single driver scale.

The application of graphene in new light-emitting devices has been extensively studied since the demonstration of the ultrafast luminescence from single-layer graphene. The control of luminescence using doping techniques is crucial for these applications. In particular, for the application of graphene in flexible and wearable devices, electrochemical doping is a promising approach, and its influence on luminescence properties of the resulting material needs to be examined. In this study, we demonstrate the effect of the electrochemical doping of graphene using an ion gel on the photoluminescence (PL) of graphene at the emission energy ℏω of 0.9 eV. The Fermi energy EF of graphene was controlled from +40 to −560meV, and femtosecond PL was observed. The PL intensity was maximum when EF was −440meV (|EF|≈ℏω/2). This trend of the PL intensity is due to (i) an increase in the PL emission rate owing to the doping-induced empty states in the valence band acting as the final states of the radiative relaxation of hot electrons and (ii) an increase in the non-radiative relaxation rate owing to the acceleration of carrier–carrier scattering by the doping-induced increase in the density of states around the EF.

Phonons are important lattice vibrations that affect the thermal, electronic, and optical properties of materials. In this work, we studied infrared phonon resonance in a prototype van der Waals (vdW) material—hexagonal boron nitride (hBN)—with the thickness ranging from monolayers to bulk, especially on ultra-thin crystals with atomic layers smaller than 20. Our combined experimental and modeling results show a systematic increase in the intensity of in-plane phonon resonance at the increasing number of layers in hBN, with a sensitivity down to one atomic layer. While the thickness-dependence of the phonon resonance reveals the antenna nature of our nanoscope, the linear thickness-scaling of the phonon polariton wavelength indicates the preservation of electromagnetic hyperbolicity in ultra-thin hBN layers. Our conclusions should be generic for fundamental resonances in vdW materials and heterostructures where the number of constituent layers can be conveniently controlled. The thickness-dependent phonon resonance and phonon polaritons revealed in our work also suggest vdW engineering opportunities for desired thermal and nanophotonic functionalities.
