Deep Learning for Orthopedic Disease Based on Medical Image Analysis: Present and Future

Since its development, deep learning has been quickly incorporated into the field of medicine and has had a profound impact. Since 2017, many studies applying deep learning-based diagnostics in the field of orthopedics have demonstrated outstanding performance. However, most published papers have focused on disease detection or classification, leaving some unsatisfactory reports in areas such as segmentation and prediction. This review introduces research published in the field of orthopedics classified according to disease from the perspective of orthopedic surgeons, and areas of future research are discussed. This paper provides orthopedic surgeons with an overall understanding of artificial intelligence-based image analysis and the information that medical data should be treated with low prejudice, providing developers and researchers with insight into the real-world context in which clinicians are embracing medical artificial intelligence.
Assessment of surface water management institutions: a case of public irrigation schemes in northern Algeria

The pressure on water resources that Algeria encounters is due to the scarcity and the water demand increase by different sectors of activity. This induces managers to reconsider the traditional supply management approach. The new water policies aim to adopt water demand management by improving the efficiency of its use in the agricultural sector, which consumes more than 59% of freshwater withdrawals. Economic, regulatory, and voluntary instruments have been adopted for better governance of water resources. This study aims to (i) define institutional arrangements on the exploitation of surface water in large irrigation schemes in Algeria and (ii) assess the effectiveness of the current water management instruments. Findings from farmers’ and water distribution agencies’ surveys suggest that objectives expected by the application of the different economic instruments are far from being achieved. Moreover, the absence of effective executive agencies for the implementation of regulations suggests that an improvement in the performance of public administration is necessary to achieve better governance of irrigation water in Algeria. At the local level, and despite a lack of farmers’ will to formally engage in a collective of farmers, they organize themselves around informal arrangements to overcome the challenges associated with water scarcity.
Live imaging of Yersinia translocon formation and immune recognition in host cells

Yersinia enterocolitica employs a type three secretion system (T3SS) to translocate immunosuppressive effector proteins into host cells. To this end, the T3SS assembles a translocon/pore complex composed of the translocator proteins YopB and YopD in host cell membranes serving as an entry port for the effectors. The translocon is formed in a Yersinia-containing pre-phagosomal compartment that is connected to the extracellular space. As the phagosome matures, the translocon and the membrane damage it causes are recognized by the cell-autonomous immune system. We infected cells in the presence of fluorophore-labeled ALFA-tag-binding nanobodies with a Y. enterocolitica strain expressing YopD labeled with an ALFA-tag. Thereby we could record the integration of YopD into translocons and its intracellular fate in living host cells. YopD was integrated into translocons around 2 min after uptake of the bacteria into a phosphatidylinositol-4,5-bisphosphate enriched pre-phagosomal compartment and remained there for 27 min on average. Damaging of the phagosomal membrane as visualized with recruitment of GFP-tagged galectin-3 occurred in the mean around 14 min after translocon formation. Shortly after recruitment of galectin-3, guanylate-binding protein 1 (GBP-1) was recruited to phagosomes, which was accompanied by a decrease in the signal intensity of translocons, suggesting their degradation. In sum, we were able for the first time to film the spatiotemporal dynamics of Yersinia T3SS translocon formation and degradation and its sensing by components of the cell-autonomous immune system.
Parental education, divorce, and children’s educational attainment: Evidence from a comparative analysis

BACKGROUND Children who experience parental divorce have worse long-term educational attainment than children living in intact families. Less clear is the extent to which heterogeneity in the divorce penalty depends on parents’ socioeconomic background and contextual characteristics. OBJECTIVE This study focuses on the negative consequences of parental divorce for children’s tertiary education attainment, their heterogeneity by parental socioeconomic background, and variation across time and space. METHOD Single-level and multi-level linear probability models are estimated on several data sources in a comparative analysis of European countries and US regions. Different operationalizations of parental divorce are employed, including both marital and nonmarital dissolutions. RESULTS Results show a stronger negative association between parental divorce and the probability of obtaining a university degree for children of highly educated parents. This holds across different birth cohorts in both Europe and the United States, largely irrespective of the country or region of residence, the dataset, and the operationalization of divorce and parental education. Higher divorce and university enrollment rates increase the absolute size of the divorce penalty, but do not substantially alter its pattern of heterogeneity. 1 Università degli Studi di Firenze, Italy.

Guetto, Bernardi & Zanasi: Parental education, divorce and children’s educational attainment 66 https://www.demographic-research.org CONCLUSION Children of high-SES families have more to lose in terms of the family resources relevant to achieving a university degree and are thus more negatively affected by parental divorce. CONTRIBUTION The finding that the association between parental divorce and children’s educational attainment is stronger for children of highly educated parents across a variety of social and institutional environments has implications for the role of divorce in the reproduction of social inequalities.
Rural microgrids – ‘Tragedy of commons’ or ‘community collective action’

ABSTRACT Providing universal electricity access is India’s national priority and part of its global commitment to sustainable development. India has an increasing urban-rural gap in electricity consumption. Microgrids can evolve as a viable solution, especially for last-mile connectivity in rural areas. Through a field survey, this paper evaluates the functioning and governance of solar microgrid projects in eight villages of Komna Block in the eastern province of India. These projects were hailed for their holistic implementation with a significant portion of the budget invested in governance aspects. However, the field survey showed that most of these projects were dysfunctional and had suffered from the ‘tragedy of commons’, where people over-exploit a common resource leading to its collapse. One of the projects, which was functional, reflected ‘community collective action’, where people cooperate to manage the system. An analysis of these projects revealed that, for the sustainability of microgrids, it is imperative to acknowledge energy aspirations of rural households, to develop the capacity of the local youth for microgrid maintenance, to have a governance based on the common-pool resource theory, and to have complementarity with the main grid. The study also examined the inconsistencies in the definition of microgrids and proposed a forward-looking definition for the global south.
The Effects of Cognitive Behavior Therapy and Social Skill Training among Schizophrenia with Risk of Violent Behavior

BACKGROUND: Schizophrenia is a condition in which people suffer from impaired ability to think, perceive, and show emotional responses and interact socially. Patients with schizophrenia can experience the risk of violent behavior (RVB). Psychotherapy is needed to deal with the problem. AIM: This study aimed to investigate the effects of cognitive behavior therapy (CBT) and social skill training (SST) on signs and symptoms of risks of violent behavior (RVB). METHODOLOGY: This study employed a quasi-experimental without a control group. The research samples used purposive sampling were 30 patients with symptoms of risks of violent behavior. Meanwhile, the measurement used the sign and symptom questioners of risks of violent behavior (Z = 0.791). RESULT: This study revealed that signs and symptoms decreased significantly (p < 0.05) from 10.45 to 5.41 after the respondents had obtained the CBT. Moreover, after the respondents had received CBT and SST, the sign and symptoms decreased significantly (p < 0.05) from 5.41 to 0.52. CONCLUSION: This study recommends that the combination of CBT and SST be administered to patients with schizophrenia with risks of violent behavior.
REAL CASE INTERACTION BETWEEN A SYMPATHETIC INRUSH AND A RESONANT SYSTEM

An incident occurred in the Portuguese HV electrical distribution system, where an EHV/HV power transformer supplied by the EHV transmission system was tripped by an elevated fifth harmonic residual current on its secondary side, leading to a power outage. At the time, a second power transformer was being energized for parallel operation, in order to restore normal grid operation after reconfiguration from commissioning works. A study was conducted to identify the origin of the fifth harmonic current, and to establish possible mitigation solutions. It was found that the sympathetic inrush, caused by the inrush of the second transformer, produced a rich harmonic disturbance in the zero-sequence voltage component on the HV side, which in turn excited an existing zero-sequence resonance between the transformer and the extensive underground cable network. This paper presents the conducted analysis, along with the measures taken to prevent further unwanted trips and to lower the overall system disturbance.

Overcoming Cloud Concerns with Trusted Execution Environments? Exploring the Organizational Perception of a Novel Security Technology in Regulated Swiss Companies

Trusted execution environments are a new approach for isolating data, specific parts of code, or an entire application within untrusted cloud environments. This emerging security technology could also enable the migration to cloud infrastructures for organizations working with highly sensitive data. As current research does not address the organizational perception of trusted execution environments (TEEs), we conducted an explorative study to clarify the technological, environmental, and organizational views on this technology by health care, life sciences, and banking companies in Switzerland. The interview findings show that in these industries, missing technological knowledge as well as privacy and process regulation are perceived to be the most critical driver for organizational adoption of TEEs. The identified low intrinsic motivation to adopt novel technologies permits us to conclude that clarifying the regulatory impact of TEEs could drive future adoption by organizations.
Simple Slot Antenna With Polarization Diversity

In this letter, a dual-feed circularly polarized slot antenna with polarization diversity is proposed. The proposed antenna consists of a circular slot that acts as a radiator, a dual-microstrip line as a feeding structure, a slit applied to a ground plane (GND), and a protruded stub. The circular polarization (CP) is easily obtained by protruding stub because it acts as perturbation in circular slots. The good isolation between two ports is achieved by the protruding stub and the slit applied to ground plane. From the measured results, the CP operating bandwidth is 22.4%. The isolation is less than −15 dB within the operating bandwidth.
Schedulability Analysis for Coscheduling Real-Time Tasks on Multiprocessors

The real-time coscheduling problem, where tasks may have multiple phases executing on different types of processors, is known to be hard. The (already hard) self-suspending task scheduling simplifies the coscheduling problem by assuming that the latency a task may experience on the other type of processors is naturally bounded, which is unfortunately not true in practice. In this article, we present a novel analysis technique, namely, the vertical view analysis, for analyzing the schedulability of coscheduling sporadic tasks under global earliest-deadline-first (GEDF) on a heterogeneous multiprocessor consisting of two types of processors. We derive both hard (no deadline miss) and soft (bounded response times) real-time utilization-based tests. To the best of our knowledge, these results are the first-of-its-kind for the coscheduling problem and may allow real-time schedulability analysis to be carried out on more practical scenarios under heterogeneous computing.
PD1+ T-cells correlate with Nerve Fiber Density as a prognostic biomarker in patients with resected perihilar cholangiocarcinoma

Background & Aims Perihilar cholangiocarcinoma (pCCA) is a rare hepatobiliary malignancy. Nerve fiber invasion (NFI) shows cancer invading the nerve and is considered an aggressive feature. Nerve fiber density (NFD) consists of small nerve fibers without cancer invasion and is divided into high NFD (high numbers of small nerve fibers) or low NFD (low numbers of small nerve fibers). We aim to explore differences in immune cell populations and survival. Methods We applied multiplex immunofluorescence (mIF) on 47 pCCA surgically resected patients and investigated the immune cell composition in the tumor microenvironment (TME) of different nerve fiber phenotypes (NFI, high and low NFD). Extensive group comparison was carried out and the association with overall survival (OS) was assessed. Results The NFI ROI was measured with highest CD68+ macrophage levels among 3 ROIs (NFI compared to tumor free p= 0.016 and to tumor p=0.034). Further, for NFI patients the density of co-inhibitory markers CD8+PD1+ and CD68+PD1+ were more abundant in the tumor rather than NFI ROI (p= 0.004 and p= 0.0029 respectively). Comparison between patients with NFD and NFI groups, the signals of co-expression of CD8+PD1+ as well as CD68+PD1+ were significantly higher in the high NFD group (p= 0.027 and p= 0.044, respectively). The OS for high NFD patients was 92 months median OS (95% CI:41-142), for low NFD patients 20 months ((95% CI: 4-36) and for NFI group of patients 19 months (95% CI 7-33). The OS for high NFD patients was significantly better compared to low NFD (p= 0.046) and NFI (p= 0.032). Conclusions PD1+ T-cells correlate with high NFD as a prognostic biomarker, the biological pathway behind this needs to be investigated. Lay summary Nerve fibers play a dual role in the tumor microenvironment in pCCA. In our previous study, we showed that the presence of high numbers of small nerve fibers is associated with a better overall survival. In addition, we found that in high NFD patients PD1+ T-cells are significantly overexpressed. Therefore, we present high NFD as a promising prognostic biomarker. Graphical abstract

Pulmonary functional MRI: Detecting the structure–function pathologies that drive asthma symptoms and quality of life

Pulmonary functional MRI (PfMRI) using inhaled hyperpolarized, radiation‐free gases (such as 3He and 129Xe) provides a way to directly visualize inhaled gas distribution and ventilation defects (or ventilation heterogeneity) in real time with high spatial (~mm3) resolution. Both gases enable quantitative measurement of terminal airway morphology, while 129Xe uniquely enables imaging the transfer of inhaled gas across the alveolar–capillary tissue barrier to the red blood cells. In patients with asthma, PfMRI abnormalities have been shown to reflect airway smooth muscle dysfunction, airway inflammation and remodelling, luminal occlusions and airway pruning. The method is rapid (8–15 s), cost‐effective (~$300/scan) and very well tolerated in patients, even in those who are very young or very ill, because unlike computed tomography (CT), positron emission tomography and single‐photon emission CT, there is no ionizing radiation and the examination takes only a few seconds. However, PfMRI is not without limitations, which include the requirement of complex image analysis, specialized equipment and additional training and quality control. We provide an overview of the three main applications of hyperpolarized noble gas MRI in asthma research including: (1) inhaled gas distribution or ventilation imaging, (2) alveolar microstructure and finally (3) gas transfer into the alveolar–capillary tissue space and from the tissue barrier into red blood cells in the pulmonary microvasculature. We highlight the evidence that supports a deeper understanding of the mechanisms of asthma worsening over time and the pathologies responsible for symptoms and disease control. We conclude with a summary of approaches that have the potential for integration into clinical workflows and that may be used to guide personalized treatment planning.

Modelling of flicker in large real medium voltage distribution networks

Modelling of flicker in large real distribution networks has been a challenge until now, due to huge number of flicker sources contributing to total flicker levels in the network. In this paper, voltage flicker is modelled for a large real medium voltage (MV) distribution network. The total flicker is calculated from background flicker resulting from high voltage network and from flicker emission of a large number of sources in the analysed MV network. The flicker emission was modelled by statistical distributions of emission levels. Results of the simulation were compared to flicker measurements from several power quality monitors, installed in the feeders of the analysed MV network. The results show a significant similarity between the model and the measurements. Conclusion of this work is that the voltage flicker can be modelled with sufficient accuracy, even in large real MV networks.
Visceral Obesity Determined by CT As a Predictor of Short-term Postoperative Complications in Ovarian Cancer

Objective: To explore the association between visceral obesity and short-term postoperative complications in patients with advanced ovarian cancer undergoing cytoreductive surgery.Methods: Medical records were reviewed for patients with ovarian cancer. Visceral fat area, subcutaneous fat area and total fat area were measured on a single slice at the level of L3/4 of a preoperative CT scan. Univariable and multivariable analyses were performed to investigate the correlation between visceral obesity and short-term complications and to analyze the risk factors for complications after surgery.Results: Of the 130 patients, 53.8% (70/130) were presented visceral obesity. Patients with visceral obesity were older than those with nonvisceral obesity (58.3 years old vs. 52.3 years old, p = 0.001). The proportion of patients with hypertension was slightly higher (37.1% vs. 11.7%, p = 0.001). The total fat area and subcutaneous fat area were higher in patients with visceral obesity (296.9 ± 72.1 vs. 173.1 ± 67.3, p < 0.001; 168.8 ± 55.5 vs. 121.6 ± 54.3, p < 0.001). Compared with patients in the nonvisceral obese group, patients in the visceral obese group were more likely to have postoperative fever (21/70 30.0% vs. 8/60 1.25%, p = 0.023), leading to a longer length of hospital stay (21 days vs. 17 days, p = 0.009). Time from surgery to adjuvant chemotherapy for patients with visceral obesity has been delayed (24 days vs. 20 days, p = 0.037). Multivariate analysis showed that visceral obesity (OR 4.770, p < 0.001) and operation time (OR 1.008, p < 0.001) were independent predictors of postoperative complications. Conclusion: Visceral obesity is an important risk factor for short-term postoperative complications in patients with advanced ovarian cancer undergoing cytoreductive surgery.
