Published: July 2022

AbstractThis design was aimed at the requirements of the asset tracker's working time, abnormal identification, remote alarm, information prompt, using STM32 as the core MCU for data collection and processing, with a built-in GNSS wireless communication module, three-axis acceleration sensor, and other sensors, design and implement an asset tracker device that automatically recognizes and reports abnormalities. In this design, the GPS positioning information was processed, and the positioning accuracy of the device was improved. The acceleration sensor data was performed by the Kalman filter, which could effectively judge the movement of assets. The sleep-work-sleep work mode was adopted to reduce the device's power consumption and enhance the device's endurance. The test results showed that the device could reasonably identify the device's abnormal condition, quickly locate the device, and upload the device information to the server. Each working life could be applied to the tracking of all kinds of assets.

Published: July 2022

AbstractAI In this era, scene based translation and intelligent word segmentation are not new technologies. However, there is still no good solution for long and complex Chinese semantic analysis. The subjective question scoring still relies on the teacher's manual marking. However, there are a large number of examinations, and the manual marking work is huge. At present, the labor cost is getting higher and higher, the traditional manual marking method can't meet the demand The demand for automatic marking is increasingly strong in modern society. At present, the automatic marking technology of objective questions has been very mature and widely used. However, by reasons of the complexity and the difficulty of natural language processing technology in Chinese text, there are still many shortcomings in subjective questions marking, such as not considering the impact of semantics, word order and other issues on scoring accuracy. The automatic scoring technology of subjective questions is a complex technology, involving pattern recognition, machine learning, natural language processing and other technologies. Good results have been seen in the calculation method-based deep learning and machine learning. The rapid development of NLP technology has brought a new breakthrough for subjective question scoring. We integrate two deep learning models based on the Siamese Network through bagging to ensure the accuracy of the results, the text similarity matching model based on the birth networks and the score point recognition model based on the named entity recognition method respectively. Combining with the framework of deep learning, we use the simulated manual scoring method to extract and match the score point sequence of students’ answers with standard answers. The score recognition model effectively improves the efficiency of model calculation and long text keyword matching. The loss value of the final training score recognition model is about 0.9, and the accuracy is 80.54%. The accuracy of the training text similarity matching model is 86.99%, and the fusion model is single. The scoring time is less than 0.8s, and the accuracy is 83.43%.

AbstractUser browsing behavior is an important kind of implicit feedback data reflecting users’ interests and preferences in the field of recommendation system. How to make full use of user browsing behavior data and combined with other context information to improve recommendation efficiency has become a research hotspot. This paper analyzes the user micro network implicit feedback behavior of mobile intelligent terminal, and studies the influence of user attribute context on user micro network implicit feedback behavior by using binary and multiple regression analysis. The results show that the user’s age attribute, regional attribute and occupation attribute are a kind of very important context information.

Published: July 2022

AbstractAt present, the attack behavior that occurs in the network has gradually developed from a single-step, simple attack method to a complex multi-step attack method. Therefore, the researchers conducted a series of studies on this multi-step attack. Common methods usually use IDS to obtain network alert data as the data source, and then match a multi-step attack based on the correlation nature of the data. However, the false positives and omissions of the alert data based on IDS will lead to the failure of the resulting multi-step attack. Multi-source data is the basis of analysis and prediction in the field of network security, and fusion analysis technology is an important means of processing multi-source data. In response to this problem, this paper studies how to use sensitive information traffic as data to assist IDS alert data, and proposes a method for fusion of traffic and log data based on sensitive information. This article analyzes the purpose of each stage of the kill chain, and relies on the purpose to divide the multi-step attack behavior in stages, which is used to filter the source data. And according to the purpose of the multi-step attack, the kill chain model is used to define the multi-step attack model.
Symmetry properties of Wilson loops with a Lagrangian insertion
Authors: Chicherin Dmitry , Henn Johannes M. 
Published: July 2022

Abstract
Null Wilson loops in $$ \mathcal{N} $$
N
= 4 super Yang-Mills are dual to planar scattering amplitudes. This duality implies hidden symmetries for both objects. We consider closely related infrared finite observables, defined as the Wilson loop with a Lagrangian insertion, normalized by the Wilson loop itself. Unlike ratio and remainder functions studied in the literature, this observable is non-trivial already for four scattered particles and bears close resemblance to (finite parts of) scattering processes in non-supersymmetric Yang-Mills theory. Moreover, by integrating over the insertion point, one can recover information on the amplitude, as was recently done to compute the full four-loop cusp anomalous dimension. We study the general structure of the Wilson loop with a Lagrangian insertion, focusing in particular on its leading singularities and their (hidden) symmetry properties. Thanks to the close connection of the observable to integrands of MHV amplitudes, it is natural to expect that its leading singularities can be written as certain Grassmannian integrals. The latter are manifestly dual conformal. They also have a conformal symmetry, up to total derivatives. We find that, surprisingly, the conformal symmetry becomes an invariance in the frame where the Lagrangian insertion point is sent to infinity. Furthermore, we use integrability methods to study how higher Yangian charges act on the Grassmannian integral. We evaluate the n-particle observable both at tree- and at one-loop level, finding compact analytic formulas. These results are explicitly written in the form of conformal leading singularities, multiplied by transcendental functions. We then compare these formulas to known expressions for all-plus amplitudes in pure Yang-Mills theory. We find a remarkable new connection: the Wilson loop with Lagrangian insertion in $$ \mathcal{N} $$
N
= 4 super Yang-Mills appears to predict the maximal weight terms of the planar pure Yang-Mills all-plus amplitude. We test this relationship for the two-loop n-point Yang-Mills amplitude, as well as for the three-loop four-point amplitude.

Published: July 2022

AbstractMyalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a complex and debilitating disease with a substantial social and economic impact on individuals and their community. Despite its importance and deteriorating impact, progresses in diagnosis and treatment of ME/CFS is limited. This is due to the unclear pathophysiology of the disease and consequently lack of prognostic biomarkers. To investigate pathophysiology of ME/CFS, several potential pathologic hallmarks have been investigated; however, these studies have failed to report a consistent result. These failures in introducing the underlying reason for ME/CFS have stimulated considering other possible contributing mechanisms such as tryptophan (TRP) metabolism and in particular kynurenine pathway (KP). KP plays a central role in cellular energy production through the production of nicotinamide adenine dinucleotide (NADH). In addition, this pathway has been shown to mediate immune response and neuroinflammation through its metabolites. This review, we will discuss the pathology and management of ME/CFS and provide evidence pertaining KP abnormalities and symptoms that are classic characteristics of ME/CFS. Targeting the KP regulation may provide innovative approaches to the management of ME/CFS.
Three-Body Hamiltonian with Regularized Zero-Range Interactions in Dimension Three
Authors: Basti Giulia , Cacciapuoti Claudio , Finco Domenico , Teta Alessandro 
Published: July 2022

AbstractWe study the Hamiltonian for a system of three identical bosons in dimension three interacting via zero-range forces. In order to avoid the fall to the center phenomenon emerging in the standard Ter-Martirosyan–Skornyakov (TMS) Hamiltonian, known as Thomas effect, we develop in detail a suggestion given in a seminal paper of Minlos and Faddeev in 1962 and we construct a regularized version of the TMS Hamiltonian which is self-adjoint and bounded from below. The regularization is given by an effective three-body force, acting only at short distance, that reduces to zero the strength of the interactions when the positions of the three particles coincide. The analysis is based on the construction of a suitable quadratic form which is shown to be closed and bounded from below. Then, domain and action of the corresponding Hamiltonian are completely characterized and a regularity result for the elements of the domain is given. Furthermore, we show that the Hamiltonian is the norm resolvent limit of Hamiltonians with rescaled non-local interactions, also called separable potentials, with a suitably renormalized coupling constant.

Published: July 2022

AbstractWe show that certain monotone functionals on the Hardy spaces and convex functionals on the Bergman spaces are maximized at the normalized reproducing kernels among the functions of norm 1, thus proving the contractivity conjecture of Pavlović and of Brevig, Ortega-Cerdà, Seip and Zhao and the Wehrl-type entropy conjecture for the SU(1, 1) group of Lieb and Solovej, respectively.

Abstract
Introduction
Bifurcation aneurysms represent an ongoing endovascular challenge with a variety of techniques and devices designed to address them. We present our multicenter series of the pCONUS2 and pCONUS2 HPC devices when treating bifurcation aneurysms.

Methods
We performed a retrospective review of our prospectively maintained databases at 3 tertiary neurointerventional centers to identify all patients who underwent coil embolization with the pCONUS2 or pCONUS2 HPC device between February 2015 and August 2021. We recorded baseline demographics, aneurysm data, complications, immediate and delayed angiographic results.

Results
We identified 55 patients with 56 aneurysms, median age 63 years (range 42–78 years), 67.3% female (n = 37). The commonest aneurysm location was the MCA bifurcation (n = 40, 71.4%). Average dome height was 8.9 ± 4.2 mm (range 3.2–21.5 mm), average neck width 6.4 ± 2.5 mm (range 2.6–14 mm), and average aspect ratio 1.3 ± 0.6 (range 0.5–3.3). The pCONUS2 was used in 64.3% and the pCONUS2 HPC in 35.7%. The procedural technical success rate was 98.2%. Intraoperative complications occurred in 5 cases (8.9%), 4 of which were related to the coils with partial thrombus formation on the pCONUS2 HPC seen in 1 case that was resolved with heparin. In relation to the procedure and treatment of the aneurysm the overall permanent morbidity was 1.8% (n = 1/55) and mortality 0%. Delayed angiographic follow-up (48 aneurysms) at median 12 months postprocedure (range 3–36 months) demonstrated adequate occlusion of 83.4% of aneurysms.

Conclusion
The pCONUS2 and pCONUS2 HPC devices carry a high technical success rate, low complication and retreatment rate, and good rates of adequate occlusion. Larger prospective confirmatory studies are required.

Authors: Girshausen Robert , Horst Klemens , Herren Christian , Bläsius Felix , Hildebrand Frank , Andruszkow Hagen 
Published: July 2022

Abstract
Purpose
Scores are widely used for the assessment of injury severity and therapy guidance in severely injured patients. They differ vastly regarding complexity, applicability, and prognostic accuracy. The objective of this study was to compare well-established with more recently developed trauma scores as well as intensive care unit (ICU) scores.

Methods
Retrospective analysis of severely injured patients treated at a level I trauma centre from 2010 to 2015. Inclusion criteria: Age ≥ 18 years, Injury Severity Score ≥ 16 and ICU treatment. Primary endpoint was in-hospital mortality. Several scores (ISS, APACHE II, RTS, Marshall Score, SOFA, NISS, RISC II, EAC and PTGS) were assessed to determine their predictive quality for mortality. Statistical analysis included correlation analysis and receiver operating characteristic (ROC).

Results
444 patients were included. 71.8% were males, mean age was 51 ± 20.26 years. 97.4% sustained a blunt trauma. The area under the ROC curve (AUROC) revealed RISC II (0.92) as strongest predictor regarding mortality, followed by APACHE II (0.81), Marshall score (0.69), SOFA (0.70), RTS (0.66), NISS (0.62), PTGS (0.61) and EAC (0.60). ISS did not reach statistical significance.

Conclusions
RISC II provided the strongest predictive capability for mortality. In comparison, more simple scores focusing on injury pattern (ISS, NISS), physiological abnormalities (RTS, EAC), or a combination of both (PTGS) only provided inferior mortality prediction. Established ICU scores like APACHE II, SOFA and Marshall score were proven to be helpful tools in severely injured trauma patients.

AbstractBackgroundTwo‐thirds of patients undergoing liver resection for intrahepatic cholangiocarcinoma experience recurrence after surgery. Our aim was to identify factors associated with early recurrence after resection for intrahepatic cholangiocarcinoma.MethodsPatients with intrahepatic cholangiocarcinoma undergoing curative intent resection (complete resection and lymphadenectomy) were included in two centers between 2005 and 2021 and were divided into three groups: early recurrence (< 12 months after resection), delayed recurrence (> 12 months), and no recurrence. Patients experiencing early (< 90 days) postoperative mortality were excluded.ResultsAmong 120 included patients, 44 (36.7%) experienced early recurrence, 24 (20.0%) experienced delayed recurrence, and 52 (43.3%) did not experience recurrence after a median follow‐up of 59 months (IQR: 26‐113). The median recurrence‐free survival was 16 months (95% CI: 9.6–22.4). Median overall survival was 55 months (95% CI: 45.7–64.3), while it was 25 months for patients with early recurrence (p < 0.001). Patients with early recurrence had significantly larger tumors (59.1% of tumors > 70 mm in early vs. 58.3% in delayed vs. 26.9% in no recurrence group, p = 0.002), multiple lesions (65.9% vs. 29.2% vs. 11.5%, p < 0.001), and positive lymph nodes (N +) (38.6% vs. 37.5% vs. 11.5%, p = 0.005). In multivariable analysis, presence of multiple lesions (OR: 9.324; 95% CI: 3.051–28.489; p < 0.001) and positive lymph nodes (OR: 3.307. 95% CI: 1.001–11.011. p = 0.05) were associated with early recurrence.
ConclusionEarly recurrence after curative resection of intrahepatic cholangiocarcinoma is frequent and is associated with the presence of multiple lesions and positive lymph nodes, raising the question of surgery's futility in this context.
Peridynamic computational homogenization theory for materials with evolving microstructure and damage
Authors: Galadima Yakubu Kasimu , Xia Wenxuan , Oterkus Erkan , Oterkus Selda 
Published: July 2022

AbstractThis study aims to establish a framework for multiscale assessment of damage for materials with evolving microstructure based on a recently proposed peridynamic computational homogenization theory. The framework starts with replacing a material with complex microstructure with a constitutively equivalent material that is microstructurally homogenous. Constitutive equivalence between the original and the substitute materials is achieved through enforcing strain energy equivalence via the so-called nonlocal Hill’s lemma. The damage law is obtained by numerically solving boundary volume constraint problem of an RVE. The result from the analysis of the RVE problem was compared with the previously published result to establish the validity of the proposed framework. The comparison shows good agreement between result obtained using the proposed framework and those reported in the literature.

Published: July 2022

Abstract

Purpose
To quantify financial toxicity of female patients with breast cancer in China and investigate its factors and patients’ coping strategies.

Methods
The Comprehensive Score for Financial Toxicity (COST) is defined by using a structured questionnaire containing 12 items measuring perceived affordability of healthcare services, with the range of scoring of which being from 0 to 44 (higher score indicates lower financial toxicity). From January to March 2021, a total of 664 female patients diagnosed with stage 0–IV breast cancer were recruited from 33 public tertiary cancer hospitals located in 31 provinces of China. Multivariate linear regression models were used.

Results
The median age of patients was 48 years (range: 26–84 years), and 62.04% lived in urban areas. The median COST score was 21.00 (interquartile range: 15–26). Older age, higher household income, and better self-reported health status were associated with lower financial toxicity, while a bigger household size, being retired or unemployed, stage IV cancer, and a history of targeted therapy were associated with higher financial toxicity (all P < 0.05). Nearly half of the patients reported using at least one coping strategy, including considering quitting treatment, delaying treatment, and failing to take medicine or attend medical visits as instructed. The people with increased financial toxicity seem to adopt more coping strategies.

Conclusions
Financial toxicity and coping strategies are common among Chinese women with breast cancer. An understanding of the factors regarding financial toxicity may help oncologists and policy-makers identify at-risk patients and develop targeted interventions.
Feasibility study of measuring instantaneous angular speed of helical gears with magnetoresistive sensors

Published: July 2022

AbstractThe digitalization of industrial processes with e.g. the goal to increase the availability of production processes in general and to support the individualization of many products in particular leads to an increasing demand in sensor data. The state of the art for condition monitoring of involute gear trains is the measurement of structure-borne vibration with acceleration sensors. New approaches, such as measuring the instantaneous angular speed (IAS), are gaining in popularity. Machine manufacturers usually wish to use existing sensors or measurement points, where little or no effort is needed to implement the sensor concept. Magnetoresistive (MR) sensors fulfil this complex set of requirements to a high degree: They are comparatively easy to integrate, can be added as an optional component and provide sufficient accuracy.The authors have developed different sensor concepts using MR sensors for measuring IAS in a 1-stage helical gear box. Multiple tests with artificial tooth flank damages have been carried out to evaluate the damage detection potential of the sensor concepts. Finally, a spectrum analysis of the first gear mesh frequency and surrounding sidebands demonstrates the capability for detecting tooth flank damage with different MR sensor concepts.
Emotional facial palsy: an unusual and rarely explored neurological sign
Authors: Miele Giuseppina , Lavorgna Luigi , Marrapodi Maria Maddalena , Abbadessa Gianmarco 
Published: July 2022

Abstract
The anatomy of the cortico-bulbar tract that drives voluntary movements of mimic muscles is well described. Some cases of facial palsy with inverse automatic-voluntary dissociation (emotional facial palsy; EFP) are reported in the literature. These cases suggested a completely independent path of the fibers whose lesion results in EFP. We aimed to review the clinical reports of EFP available in the literature to characterize the anatomical aspect of the fibers whose lesion results in the isolated impairment of spontaneous smiling. Cortico-pontine fibers that control spontaneous smiling arise from the medial surface of the prefrontal cortex and descend through the anterior limb of the internal capsule, thalamus, and brain steam, independently from those that control voluntary movement. The mesial temporal lobe, particularly the amygdala, plays a crucial role in the network driving emotionally evoked facial expressions. We would highlight the relevance of an unusual and rarely explored neurological sign that could be added to clinical examination in ruling out focal brain pathology, such as stroke, tumors, or multiple sclerosis.
