Authors: Ren Zhiheng , Dong Shuwen , Zhang Yueqiao , Chen Xuanhua , Shi Wei , Zhang Yu
Published: July 2022

The Middle Jurassic intracontinental shortening event in East Asia, known as episode A of the Yanshanian Movement in the eastern North China Craton and the first phase of the Daebo Orogeny in the Korean Peninsula, respectively, has been thoroughly studied during the past two decades. However, the timing of its beginning, duration, and deformational processes are still highly controversial because few studies have probed the correlations between episode A of the Yanshanian Movement and the first phase of the Daebo Orogeny. The Tianshifu-Dongyingfang basin, located in the northern Liaodong Peninsula, is filled with complete Jurassic sequences that can be compared with those in the eastern North China Craton to the west of the Tan-Lu fault zone and the Korean Peninsula. Regional stratigraphic correlations suggest that the Tianshifu-Dongyingfang basin contains not only the syntectonic conglomerates, but also the lower and upper unconformities A1 and A2 of episode A of the Yanshanian Movement, which separated the syntectonic conglomerates from the underlying Early–Middle Jurassic coal measures and the overlying Late Jurassic red beds, respectively. Detailed field survey and structural analysis show that the development of syntectonic conglomerates and unconformities A1 and A2 were controlled by the imbricate thrust fault system in the basement, which resulted from the WNW–ESE compression inversed from the fault-slip data. The youngest detrital zircon U-Pb ages obtained near unconformities A1 and A2 show that the WNW–ESE compression of episode A of the Yanshanian Movement in the Liaodong Peninsula initiated at ca. 171 Ma and ended at least by 163 Ma. Our new structural and geochronological data, combined with data from the neighboring areas, suggest that episode A of the Yanshanian Movement and the first phase of the Daebo Orogeny belong to a single intracontinental shortening event, the compressional deformation of which was derived from the westward, lowangle subduction of the Paleo-Pacific plate and transmitted to the Korean and Liaodong Peninsulas at ca. 172–170 Ma and to the eastern North China Craton to the west of the Tan-Lu fault zone at 170–165 Ma.
Quality of life in children with glaucoma: a qualitative interview study in Australia
Authors: Knight Lachlan S W , Ridge Bronwyn , Staffieri Sandra E , Craig Jamie E , Prem Senthil Mallika , Souzeau Emmanuelle
Published: July 2022

Objective

Childhood glaucoma is a chronic vision-threatening condition that may significantly impact an individual’s psychosocial well-being. There is a paucity of literature investigating the quality of life (QoL) in children with glaucoma. The aim of this study was to investigate and report on the QoL issues encountered by children with glaucoma.

Design

This is a qualitative interview study. Data were collected through semistructured interviews. NVivo V.12 software (QSR International Pty Ltd, Melbourne, Australia) was used to analyse and code data to identify QoL themes. The prominence of QoL themes was determined by the number of children who raised issues connected to the corresponding theme.

Setting

Interviews were conducted via telephone or videoconferencing between April 2020 and July 2021.

Participants

Eighteen children with glaucoma, aged 8–17 years, who resided in Australia, were recruited from the Australian and New Zealand Registry of Advanced Glaucoma.

Results

Median child age was 12.1 years (IQR: 9.7–14.5 years) and 33% were female. Seven QoL themes were identified: ‘coping’, ‘inconveniences’ and ‘emotional well-being’ were more prominent themes than ‘symptoms’, ‘ocular health concerns’, ‘social well-being’ and ‘autonomy’. Adaptive coping strategies included resilience throughout clinical examinations and establishing positive relationships with ophthalmologists. These minimised inconveniences related to clinic waiting times and pupillary dilatation. External to the clinical setting, children often dissociated from their glaucoma but struggled with glare symptoms and feeling misunderstood by fellow peers. Older children aged 13–17 years commonly disengaged from their glaucoma care and expressed an unwillingness to attend ophthalmic appointments. Older children further raised issues with career options, obtaining a driver’s licence and family planning under the theme of autonomy.

Conclusions

The psychosocial impact of childhood glaucoma extends beyond the clinical environment and was minimised using coping strategies. Older children may require additional social and ophthalmic support as they transition into adulthood.

Addressing CPI resistance in NSCLC: targeting TAM receptors to modulate the tumor microenvironment and future prospects
Authors: Peters Solange , Paz-Ares Luis , Herbst Roy S , Reck Martin
Published: July 2022

Lung cancer remains a leading cause of cancer death worldwide, with non-small-cell lung cancer (NSCLC) accounting for the majority of cases. Immune checkpoint inhibitors (CPIs), including those targeting programmed cell death protein-1 and its ligand (PD-1/PD-L1), have revolutionized the treatment landscape for various cancers. Notably, PD-1/PD-L1 inhibitor-based regimens now form the standard first-line therapy for metastatic NSCLC, substantially improving patients’ overall survival. Despite the progress made using CPI-based therapies in advanced NSCLC, most patients experience disease progression after an initial response due to resistance. Given the currently limited therapeutic options available for second-line and beyond settings in NSCLC, new treatment approaches are needed to improve long-term survival in these patients. Thus, CPI resistance is an emerging concept in cancer treatment and an active area of clinical research.

Among the key mechanisms of CPI resistance is the immunosuppressive tumor microenvironment (TME). Effective CPI therapy is based on shifting immune responses against cancer cells, therefore, manipulating the immunosuppressive TME comprises an important strategy to combat CPI resistance. Several aspects of the TME can contribute to treatment resistance in NSCLC, including through the activation of Tyro3, Axl, MerTK (TAM) receptors which are essential pleiotropic regulators of immune homeostasis. Their roles include negatively modulating the immune response, therefore ectopic expression of TAM receptors in the context of cancer can contribute to the immunosuppressive, protumorigenic TME. Furthermore, TAM receptors represent important candidates to simultaneously target both tumor cells and immune cells in the TME. Clinical development of TAM receptor inhibitors (TAM RIs) is increasingly focused on their ability to rescue the antitumor immune response, thereby shifting the immunosuppressive TME to an immunostimulatory TME. There is a strong biological rationale for combining TAM RIs with a CPI to overcome resistance and improve long-term clinical responses in NSCLC. Combinatorial clinical trials of TAM RIs with CPIs are underway with encouraging preliminary results. This review outlines the key mechanisms of CPI resistance, including the role of the immunosuppressive TME, and discusses the rationale for targeting TAM receptors as a novel, promising therapeutic strategy to overcome CPI resistance in NSCLC.
A micromorphological perspective on the Neoproterozoic Smalfjord and Mortensnes Formation diamictites—Varangerfjord, Norway
Authors: Menzies John
Published: July 2022

Many Neoproterozoic diamictites are glacial in origin (Young, G.M. 2018. Precambrian glacial deposits: their origin, tectonic setting, and key role in Earth evolution. In Past glacial environments. 2nd ed. Edited by J. Menzies, and J.J.M. van der Meer. Elsevier. Chapter 2, pp. 17–45. doi:10.1016/B978-0-08-100524-8.00001-4). However, many are thought to be nonglacial mass movement deposits. Discussion on the nature of Neoproterozoic climate change focuses on the controversial origin of diamictite-bearing strata and the criteria to determine the extent and nature, or not, of glacial influence on their deposition. At the macroscale, sediments (diamictites) deposited beneath palaeo-ice masses or debris flows are massive, lack few visible signs of stratification, or deformation signatures. Microscopic investigations have resulted in specific sedimentary structures being identified, indicative of stress during glacial deposition, or developed in transit within mass movements. Case examples derived from the Neoproterozoic in Varanger, Norway have been investigated that provide strain signatures of “unique sequences” of microstructures. Micromorphology, relatively new to Precambrian research, can deliver far greater detail on the depositional and deformation histories recorded by these diamictites than obtained from macroscale studies alone. The technique provides evidence of composite deformation histories of potential glacigenic and nonglacigenic sequences. Many microstructures can be observed in most diamictites. It can be demonstrated that diamictites, both glacigenic and non-glacigenic, contain most of these microstructures in varying levels of abundancy and can be separated on specific “sets” of summative structures present. At Varanger, 12 samples were analyzed for thin sectioning. As illustrative of the thin sections as a whole, 6 are presented here that offer a microscale perspective on the diamictites from this area and establish that both the Smalfjord and Mortensnes Formation diamictites are of glacial terrestrial or subaqueous origin.
Are Dutch and French languages miscible?
Authors: Seoane Luís F. , Mira Jorge
Published: July 2022

French and Dutch are two languages of different origins (Germanic vs. Romance) that coexist within the nation-state of Belgium. While they are mostly segregated throughout the Belgian territory, in Brussels they reach an actual cohabitation with a relevant bilingual population. The dominant language in Brussels shifted from Dutch to French during the late XIX century in a process known as the Francization of Brussels. The fractions of speakers of each language and of bilinguals over that time were recorded periodically until political tensions ended the censuses in the country. This relevant linguistic shift has been the object of sociopolitical studies, but the available empirical data have never before been analyzed using a theoretical mathematical model that would allow us to quantify causal factors behind the observed dynamics. Here we carry out such study for the first time, measuring effective values of perceived interlinguistic similarity and language prestige, among others. This modeling and quantification allows us to speculate about possible trajectories of fractions of speakers over time—specifically, whether Dutch and French tend to be languages that can coexist in the long term. We find that there is an overall tendency of both tongues to grow segregated over time, suggesting, in physics terms, that Dutch and French are not miscible. The scenarios that would allow for language coexistence would often see a starkly dominating language. Notwithstanding, we also discuss the costs of attempting to sustain the cohabitation despite a natural tendency to the contrary.
Local available quantum correlations of non-symmetric X-states
Authors: Bellorin R. David M. , Albrecht Q Hermann L. , Mundarain Douglas F.
Published: July 2022

Local available quantum correlations (LAQC), as defined by Mundarain et al., are analyzed for nonsymmetric 2-qubit X states, that is, X states that are not invariant under the exchange of subsystems and therefore have local Bloch vectors whose norms are different. A simple analytic expression for their LAQC quantifier is obtained. As an example, we analyze the local application of the amplitude damping channel for Werner states and general X states. Although this local quantumchannel can create quantum discord in some cases, no such outcome is possible for LAQC, which hints toward their monotonicity under LOCC operations. This work, along with our previous result for the so-called symmetric and anti-symmetric X states, completes the pursuit of exact analytical expressions for the LAQC quantifier for 2-qubit X states.
Ab-initio calculation of structural and electronic properties of ZnO and ZnSe compounds with wurtzite structure
Authors: Jafarova V. N.
Published: July 2022

Some physical properties (structural and electronic) of Zn-based wurtzite structures have been theoretically studied by the density functional theory (DFT). Ab-initio calculations were done using the plane-wave pseudo-potential method within the Atomistix ToolKit (ATK) software package. Detailed investigations on the structural and electronic properties of the binary bulk compounds, ZnO and ZnSe, have been conducted and compared with the obtained studies. Using the modified Becke–Johnson potential has successfully improved the calculated bandgap. From the first-principles calculations for investigated compounds, it is obtained that the valence band maximum and the conduction band minimum, mainly originate from O (Se) [Formula: see text]- and Zn [Formula: see text]-states. The calculated values of electronic bandgaps of both the compounds are closer to the experimental results, and studied compounds are direct bandgap semiconductors with the transition along with [Formula: see text]–[Formula: see text] symmetry.
Defect mode tunability for escherichia coli in one-dimensional photonic crystals with thin graphene layers
Authors: Segovia-Chaves Francis , Taya Sofyan A.
Published: July 2022

In this work, the transmittance spectrum for a defective one-dimensional photonic crystal was calculated. The crystal was composed of alternating GaAs and SiO2 layers, and its cavity was infiltrated by escherichia coli bacteria, which was surrounded by thin graphene layers. In this study, we assumed that the GaAs dielectric constant depends on the pressure applied. Within the photonic bandgap, a defect mode that tunes to decreasing wavelengths, as pressure increases can be observed. This shift in the transmittance spectrum is coupled with a decrease in the energy stored within the cavity. In addition, when the graphene-layer thickness was increased while maintaining the pressure constant at 0 GPa, the defect mode is tuned to a long wavelength, which favors two confined modes for thicknesses more than 33 nm.
Nonlocal symmetry classifications, nonlocal symmetry reductions, exact solutions and conservation laws of one-dimensional nonlinear Vakhnenko equation
Authors: Vinita  , Ray S. Saha
Published: July 2022

In this paper, the categorization of nonlocal symmetries of the (1+1)-dimensional nonlinear Vakhnenko equation is presented. The governing equation is turned into a set of invertibly equivalent partial differential equations (PDE) via the invertible transformation of the canonical coordinates. The nonlocal symmetries of the aforementioned PDE were derived by establishing an inverse potential system and a locally related subsystem of the system of invertibly equivalent PDEs. In addition, using similarity variables and group invariant solutions connected to nonlocal symmetry, the exact solution of the nonlinear Vakhnenkov equation is achieved. Finally, the conservation laws for the nonlinear Vakhnenko equation were developed using the multiplier method.
INTRAPRENEURIAL PERSONALITY AND INDIVIDUAL INNOVATION BEHAVIOUR IN SERVICE ORGANISATIONS: NETWORK BUILDING ABILITY AS A MEDIATOR
Authors: NASAJ MOHAMED , BADI SULAFA , MURTAGH NIAMH , BLAIQUE LAMA
Published: July 2022

The research investigates network building ability as a mediating mechanism of influence in the relationship between intrapreneurial personality and three stages of employees’ innovative behaviours: idea generation, promotion, and realisation. A quantitative research methodology was adopted with 410 questionnaires collected from employees in the UAE service sector and subsequently analysed using structural equation modelling. The research found a significant direct relationship between intrapreneurial personality and the idea realisation stage and no direct relationship between idea generation and idea promotion. In addition, network building ability was found to mediate these relationships, underlining the importance of building networks for intrapreneurial employees to innovate. These results across the three main stages of individuals’ innovative behaviours may enrich our teachable skills to improve individuals’ innovative behaviour.
Optimal Charging Oriented Sensor Placement and Flexible Scheduling in Rechargeable WSNs
Authors: Wu Tao , Yang Panlong , Dai Haipeng , Xiang Chaocan , Xu Wanru
Published: July 2022

The recent breakthroughs in Wireless Power Transfer (WPT) facilitate supporting rechargeable sensors to enrich a series of energy-consuming applications. However, most charging scheduling schemes in rechargeable wireless sensor networks (WSNs) focus on sensing tasks instead of charging utility, which leaves a considerably high performance gap in the optimal result. Moreover, the charging scheduling is usually non-flexible, in which a full or nothing charging policy suffers from relatively low charging coverage as well as low efficiency. In this article, we focus on how to efficiently improve charging utility when introducing charging-oriented sensor placement and flexible scheduling policy. We formulate a general maximization optimization problem under a general routing constraint, which generates great difficulty. We utilize area partition and charging discretization methods to transform into the scope of maximizing a submodular function problem. Thus, a constant approximation algorithm is delivered to construct a near optimal charging tour. We analyze the performance loss from the discretization to guarantee that the output of the proposed algorithm has more than (1-ɛ)(1-1/
e
)/4 of the optimal solution, where ɛ is an arbitrarily small positive parameter (0 < ɛ < 1). Both simulations and field experiments are conducted to evaluate the performance of our proposed algorithm.
Toward Device-free and User-independent Fall Detection Using Floor Vibration
Authors: Wu Kaishun , Huang Yandao , Qiu Minghui , Peng Zhenkan , Wang Lu
Published: July 2022

The inevitable aging trend of the world’s population brings a lot of challenges to the health care for the elderly. For example, it is difficult to guarantee timely rescue for single-resided elders who fall at home. Under this circumstance, a reliable automatic fall detection machine is in great need for emergent rescue. However, the state-of-the-art fall detection systems are suffering from serious privacy concerns, having a high false alarm, or being cumbersome for users. In this article, we propose a device-free fall detection system, namely G-Fall, based on floor vibration collected by geophone sensors. We first decompose the falling mode and characterize it with time-dependent floor vibration features. By leveraging Hidden Markov Model (HMM), our system is able to detect the fall event precisely and achieve user-independent detection. It requires no training from the elderly but only an HMM template learned in advance through a small number of training samples. To reduce the false alarm rate, we propose a novel reconfirmation mechanism using Energy-of-Arrival (EoA) positioning to assist in detecting the human fall. Extensive experiments have been conducted on 24 human subjects. On average, G-Fall achieves a 95.74% detection precision on the anti-static floor and 97.36% on the concrete floor. Furthermore, with the assistance of EoA, the false alarm rate is reduced to nearly 0%.
Data and Computation Reuse in CNNs Using Memristor TCAMs
Authors: de Moura Rafael Fão , de Lima Joao Paulo Cardoso , Carro Luigi
Published: July 2022

Exploiting computational and data reuse in CNNs is crucial for the successful design of resource-constrained platforms. In image recognition applications, high levels of input locality and redundancy present in CNNs have become the golden goose for skipping costly arithmetic operations. One promising technique for this consists in storing function responses of some input patterns into offline lookup tables and replacing online computation with search operations, which are highly efficient when implemented by emerging non-volatile memory technologies. In this work, we rethink both algorithm and architecture for exploiting locality and reuse opportunities by replacing entire convolutions with searches on Content-addressable Memories. By previously calculating convolution results and building compact lookup tables with our novel clustering algorithm, one can evaluate activations at constant time complexity, also requiring a single read operation of the current input tensor. Then, we devise a reconfigurable array of processing elements based on memristive Ternary Content-addressable Memories to efficiently implement the algorithmic solution and meet the flexibility requirements of several CNN architectures. Results show that our design reduces the number of multiplications and memory accesses proportionally to the number of convolutional layer channels. The average performance is 1,172 and 82 FPS for AlexNet and VGG-16 models, thus outperforming state-of-the-art works by 13×.
Focused Layered Performance Modelling by Aggregation
Authors: Islam Farhana , Petriu Dorina , Woodside Murray
Published: July 2022

Performance models of server systems, based on layered queues, may be very complex. This is particularly true for cloud-based systems based on microservices, which may have hundreds of distinct components, and for models derived by automated data analysis. Often only a few of these many components determine the system performance, and a smaller simplified model is all that is needed. To assist an analyst, this work describes afocused modelthat includes the important components (thefocus) and aggregates the rest in groups, called dependency groups. The methodFocus-based Simplification with Preservation of Tasksdescribed here fills an important gap in a previous method by the same authors. The use of focused models for sensitivity predictions is evaluated empirically in the article on a large set of randomly generated models. It is found that the accuracy depends on a “saturation ratio” (SR) between the highest utilization value in the model and the highest value of a componentexcludedfrom the focus; evidence suggests thatSRmust be at least 2 and must be larger to evaluate larger model changes. This dependency was captured in an “Accurate Sensitivity Hypothesis” based onSR,which can be used to indicate trustable sensitivity results.
Multiple Roles of Multimodality Among Interacting Agents
Authors: Lagerstedt Erik , Thill Serge
Published: July 2022

The termmultimodalityhas come to take on several somewhat different meanings depending on the underlying theoretical paradigms and traditions along with the purpose and context of use. The term is closely related toembodiment, which, in turn, is also used in several different ways. In this article, we elaborate on this connection and propose that a pragmatic and pluralistic stance is appropriate for multimodality. We further propose a distinction between first- and second-order effects of multimodality—what is achieved by multiple modalities in isolation and the opportunities that emerge when several modalities are entangled. This highlights questions regarding ways to cluster or interchange different modalities, for example, through redundancy or degeneracy. Apart from discussing multimodality with respect to an individual agent, we further look to more distributed agents and situations in which social aspects become relevant.

In robotics, understanding the various uses and interpretations of these terms can prevent miscommunication when designing robots as well as increase awareness of the underlying theoretical concepts. Given the complexity of the different ways in which multimodality is relevant in social robotics, this can provide the basis for negotiating appropriate meanings of the term on a case-by-case basis.
A Systematic Study of the Role of Cathodic Polarization and New Findings on the Soft Sparking Phenomenon from Plasma Electrolytic Oxidation of an Al-Cu-Li Alloy
Authors: Cheng Yingliang , Feng Tian , Cheng Yulin
Published: July 2022

Understanding the role of cathodic polarization and soft sparking is critical for plasma electrolytic oxidation (PEO). In this study, PEO of an Al-Cu-Li alloy has been carried out under cathodic to anodic current density ratio (R) from 0 to 3.3. Controlled potential tests and electrochemical impedance microscopy are also adopted. The results show that increased cathodic polarization improves the long-term oxide growth efficiency until an optimum soft sparking regime is reached at R = 1.2, after that the efficiency decreases and damages to the coatings occur. Interestingly, anodic potential drop, which was considered one of the characteristics of soft sparking, is absent in some cases under R = 1.2, and the coatings under R = 1.2 is also featured by a white outer layer enriched with cations. Excessive cathodic polarization (R = ∼2.0–3.3) leads to the compact coatings with highest impedance values at the early PEO stage (300 s), but they deteriorated rapidly. The complex PEO behaviors with different cathodic polarization has been explained in terms of the intercalation of hydrogen species, mass transportation affected by H2 evolution, charge extraction and hydrogen induced stresses. Reciprocally, controlled potential tests indicate that anodic polarization also suppresses the subsequent cathodic hydrogen evolution.

Here, we generated a novel intestine-specific knockout mouse model for FFA3 (Vil-FFA3) and performed a comprehensive metabolic characterization of mice in response to an obesogenic challenge. We found that Vil-FFA3 mice fed with a Western diet were largely protected from obesity, exhibiting significantly lower levels of fat mass, lower intestinal inflammation, and altered expression of intestinal incretin hormones. Results support an important role of intestinal FFA3 in contributing to metabolism and in the development of diet-induced obesity.

Published: July 2022

This study is one of the first to investigate the effects of insulin on medium and larger extracellular vesicles (EVs) in relation to metabolic insulin sensitivity and fuel use in adults with metabolic syndrome. Our data suggest that insulin infusion decreases the concentration of total particle counts, mainly due to reductions in medium-sized EVs. Furthermore, EVs, predominantly medium-sized, are inversely associated with metabolic flexibility.
Modeling relationships between rhythmic processes and neuronal spike timing

Published: July 2022

Statistical models that incorporate neural spiking history and relationships to the phase of ongoing oscillations in the local field potential robustly capture and predict neuronal engagement in rhythmic processes. These models constitute a powerful tool to systematically test explicit hypotheses regarding the specific rhythmic currents that constrain neural spiking activity over time and during different behaviors.

Published: July 2022

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is an adjuvant treatment for severe acute respiratory distress syndrome (ARDS) with refractory hypoxemia. Contraindications to therapeutic anticoagulation must be ruled out prior to ECMO implementation. We report the case of a 17-year-old male admitted in intensive care unit (ICU) for penetrating chest trauma due to multiple gunshot wounds. The body computed tomography (body CT scan) documented right pulmonary contusions and a homolateral hemothorax. His condition rapidly deteriorated with refractory hypoxemia due to lung contusion requiring invasive mechanical ventilation (IMV) and polytransfused hemorrhagic shock. During his stay in ICU, venovenous ECMO (VV-ECMO) was implemented twice, firstly for trauma-induced ARDS and secondly after thoracic surgery. This case emphasizes the successful use of VV-ECMO in posttraumatic ARDS without increasing the risk of bleeding.

Authors: Demir Mesut , Akın Melih , Yücel Nurdan , Unal Aydin , Gürel Duygu , Yaşa Eren
Published: July 2022

Objective. Peptic ulcer disease (PUD) in children is an uncommon disorder. An estimated 1.3 percent to 20 percent of people die from perforated peptic ulcers (PPU), a PUD consequence. Using a database, we assess the prevalence and prognosis of PPU in patients. We also do radiological and laparoscopic operations for PPU in young patients. In pediatric patients, sufficient accumulation of knowledge about laparoscopic repair is at the level of case reports. This study aims to assess the results in pediatric cases operated for PUP by open or laparoscopic surgery and determine the role of computed tomography (CT) in diagnosing PUP. Methods. Data was collected from the Department of Pediatric Surgery, Sisli Hamidiye Etfal Training and Research Hospital, Turkey, from 2015 to 2020. Patients under 18 years of age who were operated on for PUP between 2015 and 2020 were divided into two groups. Group 1 involved those patients operated by laparoscopic surgery, whereas Group 2 involved those used by open surgery. Both groups were retrospectively evaluated in terms of demographic data, clinical findings, preoperative‐intraoperative findings and surgical methods (open or laparoscopic), duration of surgery, duration of nasogastric intubation, time of return to oral feeding, length of hospital stay, and postoperative complications. Results. 18 patients consisting of 15 boys and 3 girls were included in the study. Group 1 involved 10 patients, whereas Group 2 involved 8 patients. In Group 1, the symptom onset period was 1.6 ± 1.9 days, and in Group 2, it was 6.6 ± 6.1 days. In the erect abdominal radiographs (AXR) of 10 (58.8%) patients, the air was under the diaphragm. Six patients whose erect AXRs showed no attitude under the diaphragm but had abdominal pain and acute abdominal manifestation were given abdominal computed tomography (CT) scanning. In all patients with PUP, laparoscopic/open surgery involves primary suturing and repair by omentoplasty (Graham patch). The mean operative time was 87.0 ± 26.3 minutes in Group 1 and 122.5 ± 57.6 minutes in Group 2. The mean length of hospital stay was 3.9 ± 1.3 days in Group 1 and 5.8 ± 2.1 days in Group 2. Neither group developed any major surgical complications. Conclusions. Adolescents with a history of sudden onset and severe abdominal pain may present with peptic ulcer perforation even if there is no known diagnosis of peptic ulcer or predisposing factor. In cases suspected of PUP, it is vital to order and carefully examine erect AXR, which is an easy and inexpensive method. Computed tomography should be the first choice in patients without free air in ADBG but whose anamnesis and findings match peptic ulcer perforation.

Authors: Xu Siping , Chen Lan
Published: July 2022

As one of the indispensable basic branches of computer vision, visual object tracking has very important research value. Therefore, a deep learning based on robot vision tracking is evaluated. Based on the basic principles of target tracking and search principle, a deep learning algorithm for visual tracking is constructed, and finally, evaluated, and simulated. The results showed that the accuracy rate increased from 90.9% to 90.13% after the addition of channel attention mechanism module. Variance was reduced from 3.78% to 1.27%, with better stability. The EAO, accuracy, and robustness of the algorithm are better than those without significant region weighting strategy. The strategy of using the improved residual network SE-ResNet network to extract multiresolution features from the correlation filtering framework is effective and helpful to improve the tracking performance.

Published: July 2022

Gastric carcinoma (GC) is one of the most common malignancies in the world with the great early screening challenges. The study is aimed at establishing a new detection method for early screening GC using time-resolved fluorescence immunoassay (TRFIA) via quantitative detection of gastrin-17 (G-17) and carbohydrate antigen 724 (CA724) in serum. Time-resolved analyzer measured the fluorescence intensity. The standards of G-17/CA724 were used for drawing the standard curve, which is used to calculate the concentration of G-17 and CA724 in serum sample. The sensitivity for G-17 was 0.54 pg/mL and for CA724 was 0.28 U/mL with a wide-range analyze concentration (0.1-1000) pg/mL or U/mL. The average recoveries ranged from 100.52% to 110.30% for G-17 and 103.02% to 116.00% for CA724. All CVs of the intra- and interassay were below 10% with high specificity. There was a high Pearson coefficient between this TRFIA method and the commercially available kits (Pearson

r

0.9117 for G-17 and 0.9449 for CA724). Additionally, the cutoff value was 88.41 pg/mL and 5.47 U/mL for CA724 in health subjects. This study established a TRFIA method for simultaneous detection of the concentrations of G-17 and CA724 in serum, which provide a new method for sensitive, accurate, and specific early screening of gastric cancer.

Data Recovery Technology Based on Subspace Clustering
Authors: Sun Li , Song Bing
Published: July 2022

High-dimensional data usually exist asymptotically in low-dimensional space. In this study, we mainly use tensor t-product as a tool to propose new algorithms in data clustering and recovery and verify them on classical data sets. This study defines the “singular values” of tensors, adopts a weighting strategy for the singular values, and proposes a tensor-weighted kernel norm minimization robust principal component analysis method, which is used to restore low-probability low-rank third-order tensor data. Experiments on synthetic data show that in the recovery of strictly low-rank data, the tensor method and weighting strategy can also obtain more accurate recovery when the rank is relatively large, which improves the volume of the rank. The proposed method combines the two and reflects its superiority through the restoration of 500 images under a small probability noise level.

With the emergence and development of computer technology, the computing power of computer is also constantly improving and has driven the development of other fields. As an important way to improve the computing power, availability, and reliability of computer system, parallel computing is the hot spot and trend of the development of computer technology. This paper introduces the technical background and basic knowledge of parallel computing. Aiming at the problem of scheduling independent tasks and scheduling related tasks, this paper proposes a method of transforming independent tasks into related tasks and unifies the model. With the progress of mobile Internet technology, the rapid growth of mobile terminals and data traffic has spawned a large number of computing intensive and delay sensitive applications. In 5G heterogeneous cellular networks, users may become computationally demanding and delay sensitive. MEC server can solve the problem of its own computing power and battery capacity limitation. Music and cultural institutions provide City Music and cultural products. With the rapid development of modern cities, unbalanced, disordered, and large-scale music and cultural institutions cannot meet the needs of urban residents for music and culture in essence. From the perspective of urban music and cultural institutions, combined with the characteristics of music and cultural intelligence, this paper analyzes the fairness, accessibility, and attraction of the institutions through field research and GIS technology and analyzes the music. From the perspective of facility layout, it analyzes the problems and pain points of music and cultural intelligence layout, such as disorder, imbalance, and failure. In this paper, we use parallel computing technology to optimize intelligent placement of music and cultural facilities, to provide technical basis for related research.

Digital-Based Analysis of Speech Rehabilitation Data for Preschool-Age Exceptional Children
Authors: Fu Zhonglian
Published: July 2022

China has the largest number of hearing and speech disorders in the world. According to the second sample survey of the disabled conducted in 2006, there were 27.8 million disabled people in Hong Kong, about half of whom were disabled. The disabled account for 1.53%, and there are about 13,7000 hearing impaired children aged 0 to 6, an increase of about 2.3 million every year. About 2.3 million new babies are born each year. Research shows that more than 95% of exceptional children have been compensated for their residual hearing. How do 95% of hearing-loss children effectively use their remaining rumors? Technical assistance and scientific rehabilitation are effective tools to enable hearing impaired children to use their residual hearing. Therefore, this paper proposes a digital analysis method for speech rehabilitation data of preschool exceptional children to ensure that exceptional children can effectively obtain speech rehabilitation services and enhance their language ability.

It has been shown that the class of fuzzy sets has a quasilinear space structure. In addition, various norms are defined on this class, and it is given that the class of fuzzy sets is a normed quasilinear space with these norms. In this study, we first developed the algebraic structure of the class of fuzzy sets F(ℝn) and gave definitions such as quasilinear independence, dimension, and the algebraic basis in these spaces. Then, with special norms, namely, ‖u‖q = where 1 ≤ q ≤ ∞, we stated that (F(ℝn), ‖u‖q) is a complete normed space. Furthermore, we introduced an inner product in this space for the case q = 2. The inner product must be in the form. For u, v ∈ F(ℝn). We also proved that the parallelogram law can only be provided in the regular subspace, not in the entire of F(ℝn). Finally, we showed that a special class of fuzzy number sequences is a Hilbert quasilinear space.

This study involves the application of timber‐based bracings elements. For this purpose, seismic analyses are performed on special portal steel frames without the brace and diagonally braced with Glued Laminated Timber (glulam) and Timber‐Steel Buckling Restrained Brace (TS‐BRB), and the results are compared with the same configuration using steel Hollow Structural Sections (HSS) bracing, using OpenSees structural analyzer. First, to verify the accuracy of the modeling, the numerical results are compared with experimental measurements on several types of elements: (a) diagonally braced frame with steel Hollow Structural Sections with a concentrically steel braced frame which was tested by the quasi‐static method under cyclic loading protocol by previous researchers, (b) diagonally glulam braced frame with results of shake table tests on single‐story timber braced frames, and (c) Timber‐Steel Buckling Restrained Brace (TS‐BRB) frame with experimental results of Heavy Timber Buckling‐Restrained Braced Frame (HT‐BRB). In the second step, the aforementioned timber base bracing alternatives (glulam, TS‐BRB) are applied in the special portal steel frame, then the seismic performance of the frame is investigated under pushover, cyclic, time history, and incremental dynamic analysis (IDA), and then the results are compared with the behavior of similar portal frame in two conditions without the brace and diagonally braced with the steel‐HSS brace. Results showed that steel‐HSS, glulam, and timber‐steel buckling restrained braces have significant roles in energy dissipation, increasing shear capacity, decreasing interstory drift, and decreasing weight and cost of estimation of the structure.
Risk Warning of Independent Intellectual Property Rights of Small- and Medium-Sized Scientific and Technological Enterprises Using Deep Learning
Authors: Wu Junzheng
Published: July 2022

Strengthening the construction of intellectual property rights of SM-TE (small and medium-sized scientific and technological enterprises) in China is an important measure to speed up the development of SM-TE, and improve their scientific and technological innovation ability and market competitiveness. In this paper, a patent recommendation algorithm based on deep semantic similarity is proposed to solve the problem of low calculation accuracy of similarity matrix among users in sparse interaction matrix. The algorithm trains the patent corpus, and obtains the Doc2vec DL (Deep Learning) model, and then constructs the semantic similarity matrix among patents through the DL model. On this basis, to further improve the modeling ability of semantic expression and feature extraction, this paper optimizes CNN (Convolutional Neural Network) model, using a variety of pretrained word vector models, multi-layer classifiers, etc., to improve the model accuracy and generate feature vectors of different dimensions. The results show that the accuracy, recall rate and F1 value of the proposed algorithm are better than those of the traditional recommendation algorithm, which are 22.41%, 20.86% and 21.51% respectively. The experiment shows that this paper can guide Chinese enterprises to establish and improve the risk warning system of independent intellectual property rights, thus reducing the losses of enterprises.
