AbstractModern cutting edge technologies of chemical synthesis enable the production of unique nanostructures with excess energy and high reactivity. Uncontrolled use of such materials in the food industry and pharmacology entail a risk for the development of a nanotoxicity crisis. Using the methods of tensometry, mechanokinetic analysis, biochemical methods, and bioinformatics, the current study showed that chronic (for six months) intragastrical burdening of rats with aqueous nanocolloids (AN) ZnO and TiO2 caused violations of the pacemaker-dependent mechanisms of regulation of spontaneous and neurotransmitter-induced contractions of the gastrointestinal tract (GIT) smooth muscles (SMs), and transformed the contraction efficiency indices (AU, in Alexandria units). Under the same conditions, the fundamental principle of distribution of physiologically relevant differences in the numeric values of the mechanokinetic parameters of spontaneous SM contractions between different parts of GIT is violated, which can potentially cause its pathological changes. Using molecular docking, typical bonds in the interfaces of the interaction of these nanomaterials with myosin II, a component of the contractile apparatus of smooth muscle cells (SMC) were investigated. In this connection, the study addressed the question of possible competitive relations between ZnO and TiO2 nanoparticles and actin molecules for binding sites on the myosin II actin-interaction interface. In addition, using biochemical methods, it was shown that chronic long-term exposure to nanocolloids causes changes in the primary active ion transport systems of cell plasma membranes, the activity of marker liver enzymes and disrupts the blood plasma lipid profile, which indicates the hepatotoxic effect of these nanocolloids.

Local saliency consistency‐based label inference for weakly supervised salient object detection using scribble annotations
Authors: Zhao Shuo , Cui Peng , Shen Jing , Liu Haibo 
Published: March 2023

AbstractRecently, weak supervision has received growing attention in the field of salient object detection due to the convenience of labelling. However, there is a large performance gap between weakly supervised and fully supervised salient object detectors because the scribble annotation can only provide very limited foreground/background information. Therefore, an intuitive idea is to infer annotations that cover more complete object and background regions for training. To this end, a label inference strategy is proposed based on the assumption that pixels with similar colours and close positions should have consistent labels. Specifically, k‐means clustering algorithm was first performed on both colours and coordinates of original annotations, and then assigned the same labels to points having similar colours with colour cluster centres and near coordinate cluster centres. Next, the same annotations for pixels with similar colours within each kernel neighbourhood was set further. Extensive experiments on six benchmarks demonstrate that our method can significantly improve the performance and achieve the state‐of‐the‐art results.

Published: March 2023

AbstractAutomated breast ultrasound (ABUS) imaging system is a practical technique to automatically scan the whole breast. Automatic tumor detection plays a significant role in the clinic. However, training deep convolutional neural networks (CNNs) for tumor detection needs a large quantity of labeled data. It is time‐consuming and expensive to manually annotate tumor positions in ABUS images. In this paper, a novel semi‐supervised learning EfficientDet (SSL‐E) model is proposed for ABUS tumor detection. Our SSL‐E model solves the tumor detection problem from high similarity and serious unbalance between tumors and backgrounds. Considering the image contrast variation and tumor scale variations in ABUS images, color transformation and geometric transformation are employed for data augmentations. Then the consistency between image and its augmented version is developed, thus the robustness of the detector can be improved. Aiming at the problem of serious unbalance between tumors and backgrounds, a novel copy‐paste synthesis strategy is designed, which can generate more tumor samples and enhance tumor diversity. This method is tested on 68 tumor volumes and 68 normal volumes, including 43,248 slices (1683 tumor slices and 41,565 normal slices). It obtains a promising result with sensitivity of 90.2% and false positives per image (FPs/I) at 0.15.
Feature fusion method based on local binary graph for PolSAR image classification
Authors: Sebt Mohammad Ali , Darvishnezhad Mohsen 
Published: March 2023

AbstractThe goal of this paper is to propose a method to achieve a higher classification rate in Polarimetric Synthetic Aperture Radar (PolSAR) image classification. In our work, PolSAR features are extracted from Convolutional Neural Networks (CNNs) and also Graph Convolutional Networks (GCNs). Due to the construction of the adjacency matrix on all the data, traditional GCNs usually suffer from a substantial computational cost, particularly in large‐scale remote sensing (RS) problems. To this end, first of all, we propose a new mini‐batch GCN (called Mini‐GCN), which allows to train large‐scale GCNs in a mini‐batch fashion. More signiﬁcantly, our designed mini‐GCN is capable of inferring out‐of‐sample data without re‐training networks and improving classiﬁcation performance. Furthermore, as CNNs and GCNs can extract different types of PolSAR features, an intuitive solution to break the performance bottleneck of a single model is to fuse them. Since mini‐GCNs can perform batch‐wise network training (enabling the combination of CNNs and GCNs), we can use the feature fusion strategy. Therefore, in this paper, a local graph‐based fusion method is proposed to couple dimension reduction and feature fusion of the information extracted from the designed CNN and Mini‐GCN. Experimental results on real PolSAR data are very encouraging. Compared to the methods using only single feature and stacking all the features together, the proposed feature fusion method improves the overall classiﬁcation accuracy on the real PolSAR data sets for more than 5%. Moreover, the experiments conducted on PolSAR datasets, demonstrate the advantages of the used mini‐GCNs over the traditional GCNs and the superiority of the proposed feature fusion method with regards to the single CNN or GCN models.

AbstractAmong zygomaticomaxillary complex (ZMC) fractures presenting to a tertiary urban academic center, the authors hypothesized the presence of both clinical and radiographic predictors of operative management. The investigators conducted a retrospective cohort study of 1,914 patients with facial fractures managed at an academic medical center in New York City between 2008 and 2017. The predictor variables were based on both clinical data and features of pertinent imaging studies, and the outcome variable was an operative intervention. Descriptive and bivariate statistics were computed and the p-value was set at 0.05. In total, 196 patients sustained ZMC fractures (5.0%) and 121 (61.7%) ZMC fractures were treated surgically. All patients who presented with globe injury, blindness, retrobulbar injury, restricted gaze, or enophthalmos and a concurrent ZMC fracture were managed surgically. The most common surgical approach was the gingivobuccal corridor (31.9% of all approaches), and there were no significant immediate postoperative complications. Younger patients (38.9 ± 18 years vs. 56.1 ± 23.5 years, p < 0.0001) and patients with greater than or equal to 4 mm of orbital floor displacement were more likely to receive surgical treatment than observation (82 vs. 56%, p = 0.045), as were patients with comminuted orbital floor fractures (52 vs. 26%, p = 0.011). In this cohort, patients more likely to undergo surgical reduction were young patients with ophthalmologic symptoms on presentation and at least 4 mm displacement of the orbital floor. Low kinetic energy ZMC fractures may warrant surgical management as often as high-energy ZMC fractures. While orbital floor comminution has been shown to be a predictor for operative reduction, in this study we also demonstrated a difference in the rate of reduction based on the severity of orbital floor displacement. This may have significant implications in both the triage and selection of patients most suitable for operative repair.

AbstractEndoscopic dilation (ED) is the mainstream treatment for esophageal stricture after endoscopic submucosal dissection (ESD). However, some complex esophageal strictures do not respond well to dilation. Endoscopic radial incision (ERI) has proved to be effective in treating anastomotic strictures, but it is rarely used to treat post-ESD esophageal strictures due to technical difficulties and risks, not to mention the optimal method and timing to perform ERI. Here, we developed an integrated procedure in which ED was performed first, followed by ERI on the stiff scars that remained intact after dilation. The ED + ERI procedure resulted in complete, uniform expansion of the esophageal lumen. Between 2019 and 2022, 5 post-ESD patients who received a median number of 11 sessions of ED (range, 4–28) of ED over a period of 322 days (range, 246–584) but still had moderate to severe dysphagia were admitted. 2 or 3 sessions of ED + ERI were performed for each patient interspersed with ED. After a median number of 4 treatments (range, 2–9), all patients were symptom-free or had minimal symptoms. No serious complications occurred in any patients who underwent ED + ERI. Therefore, ED + ERI is safe, feasible, and may serve as a useful therapeutic method for refractory esophageal stricture after ESD.

Published: March 2023

AbstractFemoral neck fractures are common in patients with chronic kidney disease (CKD) due to abnormalities of bone metabolism. In patients on dialysis, femoral neck fractures have been shown to occur at a younger age than in nondialysis patients. The purpose of this study was to compare the associated complication rates of femoral neck fractures among dialysis patients treated with total hip arthroplasty (THA) versus hemiarthroplasty (HA) as well as evaluate for any differences in outcomes compared to the nondialysis patient population. This was a retrospective cohort study performed using the National Surgical Quality Improvement Program database that included 54,328 patients with femoral neck fractures managed surgically from 2006 to 2016. One-thousand seventy patients were identified as dialysis-dependent. Demographics, medical comorbidities, perioperative complication rates, and mortality rates were collected. Data was first analyzed descriptively and with analysis of variance or chi-squared analyses as appropriate. Odds ratios were then calculated for perioperative outcomes and complications. Femoral neck fractures in patients on dialysis occurred at a significantly younger age (73.3 vs. 77.0, p < 0.001) than nondialysis patients. In dialysis patients who underwent THA, complication rates, postoperative length of stay, readmission rates, and 1-year mortality were greater when compared to nondialysis patients. There were no significant differences in perioperative medical or surgical complication rates within the dialysis population when comparing THA to HA. Dialysis patients treated with THA for femoral neck fracture experience more complications compared to nondialysis patients. However, among dialysis patients treated with THA compared to HA, there were no significant differences in outcomes. THA is, therefore, a viable option for dialysis-dependent patients with femoral neck fractures who are otherwise medically stable.

Published: March 2023

Abstract
Background Increased intraocular pressure (IOP) likely secondary to an activated oculo-trigeminal reflex network is an important issue following subarachnoid hemorrhage (SAH). The relationship between the IOP and trigeminal ganglion (TGG) following experimental SAH was investigated in this study.
Methods Twenty-three rabbits were used in this study. Five rabbits (n = 5) were used as the control group, another 5 as the sham group (n = 5), and the remaining 13 (n = 13) as the study group. The study group was further divided into two groups of animals with mild (n = 6) and severe (n = 7) TGG degeneration. The IOP values were recorded. After 2 weeks, the animals were decapitated. The mean degenerated neuron density of TGGs was estimated by stereological methods and analyzed statistically.
Results The average IOP values were 11.85, 14.12, and 21.45 mm Hg in the control (n = 5), sham (n = 5), and study (n = 13) groups, respectively. The mean degenerated neuron density was 34, 237, and 3,165 mm3 in the control, sham, and study groups, respectively.
Conclusion According to the findings of this study, the experimental SAH leads to changes in IOP by affecting the TGG. By predicting and preventing IOP elevation in the setting of SAH, our findings will shed light on secondary sequelae such as glaucoma and irreversible blindness.

Published: March 2023

Abstract
Background Experience with early postoperative catheter-directed ultrasound-assisted thrombolysis (USAT) in high-risk pulmonary embolism (PE) is limited. A first case of USAT directly after pulmonary surgery is presented.
Case Description A 60-year-old female patient with two malignancies (triple negative breast cancer and pulmonary squamous cell carcinoma) underwent video-assisted lobectomy. The second postoperative day, she developed PE with hemodynamic deterioration. Note that 24 mg of alteplase was applied by USAT. After 3 days she was successfully weaned from ventilation and vasopressors.
Conclusion USAT for acute PE is possible after major pulmonary resections and seems promising if reperfusion is needed.
Adapting to a new home: resettlement and mental health service experiences of immigrant and refugee youth in Montreal
Authors: Gyan Charles , Chowdhury Farhin , Yeboah Ata Senior 
Published: March 2023

AbstractResettlement and mental health services are critical support systems for refugee and immigrant youth (RIY) as they navigate the complexities of settling into their new homes. These services play a vital role in meeting the needs of RIY and helping them feel welcomed into Canadian society. The purpose of this study is to provide insight into RIY’s experiences with resettlement and mental health service providers in Montreal, Canada. Adopting a descriptive quantitative research approach, this study utilized online surveys to gather data. The findings indicate that cultural and linguistic barriers are the major obstacles faced by refugee and immigrant youth when accessing resettlement and mental health services in Montreal. Protective resources, such as family, friends, and ethnic communities, were identified as important facilitators of successful integration into Canadian society. To improve services, cultural sensitivity should be a priority for providers, as recommended by this study. By acknowledging the significance of cultural barriers in accessing resettlement and mental health services, this study emphasizes the need for service providers to prioritize cultural sensitivity in their efforts to improve services.

Published: March 2023

We report a liquid metal microstrip antenna on a printing paper whose resonant frequency was tunable by folding the paper. The gallium-based alloy was used as liquid metal, which is instantly oxidized in ambient air. The oxidized liquid metal is easily wettable on printing paper surfaces, while it is non-wettable on laser-printed toner surfaces. An antenna with a 3 mm wide and 39 mm long copper-liquid metal overlapped-feedline linked to the liquid metal microstrip rectangle-shaped patch (40 × 31 mm2) was designed. The antenna pattern was printed on a printing paper using a laser printer. A liquid metal soaked roller was rolled on the antenna pattern printed paper, resulting in a liquid metal pattern where there was no toner. The resonant frequency of the liquid metal on the paper microstrip patch antenna was 2.88 GHz with −18.5 dB S11. The measured characteristics of the antenna were in good agreement with the simulation results. When the antenna was folded, the resonant frequency was changed to 2.68 GHz (x-axis folding) or 2.72 GHz (y-axis folding). Liquid metal on paper fabrication is simple but effective for creating custom-designed antennas that are easily re-designed and fabricated in the field.
What is a register?
Authors: Biber Douglas , Egbert Jesse 
Published: March 2023

AbstractEmpirical studies of register variation have established the existence of functional correspondence between situation/context and language use. However, previous conceptualizations of register cannot adequately account for empirical findings which have revealed (i) situational and linguistic variation among texts within registers and (ii) texts that do not belong to a register. We propose an alternative conceptualization in which registers are culturally-recognized categories, as opposed to scientifically-defined categories. This allows us to describe registers for their typical characteristics as well as the variation among texts within register categories. It also allows us to account for the functional correspondence of texts that exist outside of register categories.
Boosting the 21 cm forest signals by the clumpy substructures
Authors: Kadota Kenji , Villanueva-Domingo Pablo , Ichiki Kiyotomo , Hasegawa Kenji , Naruse Genki 
Published: March 2023

Abstract
We study the contribution of subhalos to the 21 cm forest signal. The halos can host the
substructures and including the effects of those small scale clumps can potentially boost the 21
cm optical depth in favor of detecting the 21 cm forest signals. We estimate the boost factor
representing the ratio of the optical depth due to the subhalo contribution and that due to the
host halo alone (without subhalos). Even though the optical depth boost factor is negligible for
a small host halo with the mass of order 105
M
⊙, the subhalo contribution can enhance
the optical depth by an order of magnitude for a host halo of order 107
M
⊙. The
resultant 21 cm absorption line abundance which is obtained by integrating over the halo mass
range relevant for the 21 cm forest signal can be enhanced by up to of order 10% due to the
substructures. The larger boost factor for a larger host halo would be of particular interest for
the 21 cm forest detection because the contribution of the larger host halos to the 21 cm
forest signals is smaller due to their higher temperature and less abundance than the smaller host
halos. The subhalos hence can well help the larger host halos more important for the signal
estimation which, without considering the subhalos, may not give appreciable contribution to 21 cm
forest signals.
Robustness of pair structures for nuclear yrast states*

Published: March 2023

Abstract
In this study, we investigate the robustness of pair structures for nuclear yrast states, that is, whether the structures of relevant collective pairs as building blocks of different yrast states are the same. We focus on deformed and transitional nuclei and study the yrast states of

Si,

Cr, and

Xe, whose experimental

values are 2.60, 2.40, and 2.16, respectively, using the nucleon-pair approximation (NPA) and shell-model effective interactions. For each yrast state, we consider optimized pair structures to be those providing the energy minimum for this state. To find the minimum, many full NPA calculations are performed with varying pair structures, and the numerical optimization procedure of the conjugate gradient method is implemented. Our results suggest that optimized pair structures remain the same for all states within a rotational band of a deformed nucleus. Our results also suggest that after backbending, that is, changing of the intrinsic state, the structure of the S pair, which is essential to build the monopole pairing correlation, remains approximately unchanged, whereas the structures of the non-S pairs, which are essential to build the quadrupole correlation, change significantly.
