Numerical Study on the Rising Motion of Bubbles near the Wall

Based on the volume of fluid method (VOF), the rising characteristics of bubbles in near-wall static water are studied. In this study, the influence of the wall on the rising motion of the bubble was studied by changing the distance of the bubble wall, the diameter of the bubble, the arrangement of the bubble and the size ratio, etc. The influence is expressed as the average swing amplitude of the “Z”-shaped motion when the bubble rises. The study found that in the case of a single bubble, the wall surface has a certain influence on the rise of the bubble, and its degree is affected by the bubble wall distance and the bubble diameter. The influence of bubble wall distance is more obvious. The greater the bubble wall distance, the less the bubble is affected by the wall; in the case of double bubbles, the influence of the interaction force between the bubbles is significantly greater than the wall surface.
The complete chloroplast genome sequence of Viola verecunda (Violaceae)

Abstract Viola verecunda is a perennial plant native to the mountainous areas of Northeast Asia. Here the complete chloroplast genome of V. verecunda and its phylogenetic relationships to other species within the genus Viola are reported. The complete chloroplast genome of V. verecunda is 157,843 bp in length and circular in structure with four regions: a large single-copy region (86,345 bp), a small single-copy region (17,292 bp), and a pair of inverted repeat regions (27,103 bp each). The chloroplast genome contains 111 unique genes comprising 77 protein-coding, 30 unique tRNA, and 4 unique rRNA genes. Based on the protein-coding gene sequences from eight Viola chloroplast genomes, with Balanops balansae designated as the outgroup, maximum likelihood tree analysis indicates that V. verecunda is more closely related to V. raddeana than to other Viola species. The complete chloroplast genome of V. verecunda contributes to a better understanding of the phylogenetic relationships among Viola species.
Mapping the DMAIC Tool in the Public Sector

The quality and continuous improvement of products and processes continue to play an essential role in the business context, with the need for more responsive, flexible, and responsive organizations. Among the many tools and methodologies employed, DMAIC (Define, Measure, Analyze, Improve and Control), linked to Six Sigma, is used to improve existing products or organizational processes. Nevertheless, if in the private sector, the adoption and practice of these tools and methodologies are widely used, in the public sector, in turn, the applicability of DMAIC is little employed. In this perspective, and using the methodological resource of systematic literature review, this article aims to identify the applicability of the DMAIC tool in the public sector. The review indicates that while DMAIC still has low public evidence, the tool can be efficiently applied across the industry, enabling positive results for organizations, reducing costs, delivering efficient processes, and increasing customer satisfaction.

Distortion cancellation by polyphase multipath circuits

It is well known that in balanced (or differential) circuits, all even harmonics are canceled. This cancellation is achieved by using two paths and exploiting phase differences of 180/spl deg/ between the paths. The question addressed in this paper is: what distortion products (harmonics and intermodulation products) are canceled if more than two paths (and phases) are used? These circuits are called polyphase multipath circuits. It turns out that the more paths (and phases) are used, the more distortion products are canceled. Unfortunately, some intermodulation products cannot be canceled without also canceling the desired signal. An analysis of the impact of mismatch between the paths shows that the suppression of distortion products will be larger if more paths are used. As an application example, the design of an upconversion mixer with a clean output spectrum is presented.
Vibration Signal Analysis of Chimney Blasting Based on HHT

In the blasting demolition processs of high-rise structures, the impact of blasting vibration to the environment and objects to be protected must be effectively controlled, so the blasting vibration signal is deeply analyzed [1]. In this paper, the blasting vibration signal of a chimney is analyzedbased on HHT. The blasting vibration signal is denoised by Empirical Mode Decomposition (EMD)-wavelet threshold, then using Hilbert-Huang Transform (HHT) [2] the measured blasting vibration waveform Hilbert spectrum, marginal spectrum and instantaneous energy graph are draw to analyze the chimney blasting vibration. The results show that the denoising effect of EMD-wavelet threshold is good for blasting vibration signal [3]. HHT method has a good feature identification ability when processing vibration signals, and can reflect the characteristics of data more comprehensively and accurately, which provides convenience for the study of vibration signal data.
Vision-based sensing for autonomous in-flight refueling

A significant capability of unmanned airborne vehicles (UAV's) is that they can operate tirelessly and at maximum efficiency in comparison to their human pilot counterparts. However a major limiting factor preventing ultra-long endurance missions is that they require landing to refuel. Development effort has been directed to allow UAV's to automatically refuel in the air using current refueling systems and procedures. The 'hose & drogue' refueling system was targeted as it is considered the more difficult case. Recent flight trials resulted in the first-ever fully autonomous airborne refueling operation. Development has gone into precision GPS-based navigation sensors to maneuver the aircraft into the station-keeping position and onwards to dock with the refueling drogue. However in the terminal phases of docking, the accuracy of the GPS is operating at its performance limit and also disturbance factors on the flexible hose and basket are not predictable using an open-loop model. Hence there is significant uncertainty on the position of the refueling drogue relative to the aircraft, and is insufficient in practical operation to achieve a successful and safe docking. A solution is to augment the GPS based system with a vision-based sensor component through the terminal phase to visually acquire and track the drogue in 3D space. The higher bandwidth and resolution of camera sensors gives significantly better estimates on the state of the drogue position. Disturbances in the actual drogue position caused by subtle aircraft maneuvers and wind gusting can be visually tracked and compensated for, providing an accurate estimate. This paper discusses the issues involved in visually detecting a refueling drogue, selecting an optimum camera viewpoint, and acquiring and tracking the drogue throughout a widely varying operating range and conditions.
All‐Cause and Cause‐Specific Mortality in Psoriatic Arthritis and Ankylosing Spondylitis: A Systematic Review and Meta‐Analysis

Psoriatic arthritis (PsA) and ankylosing spondylitis (AS) are chronic inflammatory diseases associated with a higher risk of cardiometabolic comorbidities compared to the general population. Individual studies examining mortality in these patients have produced conflicting results. The present study was undertaken to perform a systematic review and meta‐analysis to analyze the all‐cause and cause‐specific mortality in PsA and AS from the available literature.
An experimental consideration for road guide sign understanding in ITS

In this paper, we present a road guide sign recognition method the driver support system in intelligent transportation systems (ITS). Generally, on a guide sign, there are arrows representing directions and characters representing destinations and distances. First, arrows are detected using their shape characteristics. Next, the sign is classified using the number of arrow objects and the number of arrowheads. Then, the characters on the sign are assigned to their corresponding arrowheads by segmenting the sign using arrowhead positions. Finally, after the character recognition process, we obtain the information of directions, destinations and distances. We tested 65 images of zoomed in signs. 154 arrowheads on these signs were detected completely. In 62 images, characters were assigned to corresponding arrowheads successfully. Hence, our method is effective for sign image understanding.
Urban Metabolism of Food-Sourced Nitrogen among Different Income Households: A Case Study Based on Large Sample Survey in Xiamen City, China

Food consumption is fundamental for urban households if they are to sustain production and daily life. Nitrogen resulting from food consumption has significantly contributed to pollutant emissions in urban ecosystems. Taking Xiamen city, a rapid urbanizing area of southeast China as a case study, we evaluated the food-sourced nitrogen consumption of households based on a large simple onsite questionnaire survey, as well as differences between households in the consumption of plant-based and animal-based foods. A material flow analysis (MFA) was conducted to simulate the urban metabolism of food-sourced nitrogen and environmental emissions among different income groups. The impacts of household attributes, plant-based food consumption, and animal-based food consumption on environmental nitrogen emissions were examined with a structural equation model (SEM). Our results show that the surveyed households’ diets were more plant-based and less animal-based. Aquatic products and livestock were the source of 43.7% of food-sourced nitrogen, and 84.5% of the food-sourced nitrogen was discharge into the environment through direct discharge and waste treatment. Soil, water, and air emissions accounted for 62.8%, 30.1%, and 7.1% of the food-sourced nitrogen, respectively. Household income, household size, and household area are all associated with accelerating increases of nitrogen emissions released into the environment, though middle-income group households have the highest food-sourced environmental nitrogen emissions. On this basis, we discuss how to better manage the urban metabolism of food-sourced nitrogen, so as to improve urban household consumption, lower nitrogen emissions, and improve food security.
A Unified Variational Solution to Microstrip Array Problems

A very general variational procedure is used to compute single or coupled microstrips under the quasi-TEM approximation. The capacitance model is found by means of a unique fundamental cell. The method is essentially an extension of Smith's, but may be used to study a wider variety of problems, such as nonuniform strip arrays, coplanar striplines, and broad-side coupled strips. Moreover, it is also possible to compute the coupling capacitance between nonadjacent strips.
Group size influences light‐emitting diode light colour and substrate preference of David's Schizothoracin (Schizothorax davidi): Relevance for design of fish passage facilities

Fish passage structures have been constructed to facilitate fish movement past barriers, though the effectiveness of passage structures is highly variable. Designing fish passage structures that consider the behavioural preferences of fish under different environmental conditions (e.g., light colour, substrate type) has the potential to improve fish passage success. Similarly, whether a fish encounters a passage facility alone or in a group may influence fish behaviour. In this case, we assessed the preference of different group sizes (n = 1, 6 and 12, respectively) of David's Schizothoracin Schizothorax davidi under four different light‐emitting diode colours and eight different substrate types in the aquaria of the Houziyan Reproduction Station. We found that singletons preferred to visit the white light, cement and fine pebble, while the fish in groups preferred to visit the blue light, fine pebble and cobble. In addition, the total percentage of mobility frequency (18.3 ± 1.8%), movement velocity (20.4 ± 15.9 cm/s) and distance moved (15.8 ± 1.8 m) of singletons in blue light were much lower than that in the others. The movement velocity (3.3 ± 0.6 cm/s) of singletons on cobble was less, but the percentage of total mobility time (162.9 ± 16.0%) and distance moved (153.4 ± 19.6 m) on the cobble were much greater. Our research yielded novel insights for improving passage efficiency for this species. Findings from this study suggest there should be greater consideration of light colour and substrate type when designing fish passage facilities. Because fish almost always experience dynamic hydraulic conditions near and in fishways, additional research is needed to understand the generality of these findings in systems under lotic characteristics.
Theoretical Evaluation of the Impact of Hyperthermia in Combination with Radiation Therapy in an Artificial Immune—Tumor-Ecosystem

Simple Summary Radio-sensitizing effects of moderate or mild hyperthermia (heating up tumor cells up to 41–43 °C) in combination with radiotherapy (thermoradiotherapy) have been evaluated for decades. However, how this combination might modulate an anti-tumor immune response is not well known. To investigate the dynamic behavior of immune–tumor ecosystems in different scenarios, a model representing an artificial adaptive immune system in silico is used. Such a model may be far removed from the real situation in the patient, but it could serve as a laboratory to investigate fundamental principles of dynamics in such systems under well-controlled conditions and it could be used to generate and refine hypothesis supporting the design of clinical trials. Regarding the results of the presented computer simulations, the main effect is governed by the cellular radio-sensitization. In addition, the application of hyperthermia during the first radiotherapy fractions seems to be more effective. Abstract There is some evidence that radiotherapy (RT) can trigger anti-tumor immune responses. In addition, hyperthermia (HT) is known to be a tumor cell radio-sensitizer. How HT could enhance the anti-tumor immune response produced by RT is still an open question. The aim of this study is the evaluation of potential dynamic effects regarding the adaptive immune response induced by different combinations of RT fractions with HT. The adaptive immune system is considered as a trainable unit (perceptron) which compares danger signals released by necrotic or apoptotic cell death with the presence of tumor- and host tissue cell population-specific molecular patterns (antigens). To mimic the changes produced by HT such as cell radio-sensitization or increase of the blood perfusion after hyperthermia, simplistic biophysical models were included. To study the effectiveness of the different RT+HT treatments, the Tumor Control Probability (TCP) was calculated. In the considered scenarios, the major effect of HT is related to the enhancement of the cell radio-sensitivity while perfusion or heat-based effects on the immune system seem to contribute less. Moreover, no tumor vaccination effect has been observed. In the presented scenarios, HT boosts the RT cell killing but it does not fundamentally change the anti-tumor immune response.
Modeling of coplanar stripline discontinuities

The paper presents a technique to obtain lumped equivalent circuit models for typical coplanar stripline (CPS) discontinuities such as an open circuit, a short circuit, and a series gap in one of the strip conductors and gives their element values as a function of the discontinuity physical dimensions for a specific substrate. The model element values are determined from the discontinuity scattering parameters which are de-embedded from the measured scattering parameters using a thru-reflect-line (TRL) algorithm. In addition, the resonant frequency of a spur-slot is presented as a function of the spur length. The experimental results are validated by data obtained using the finite-difference time-domain (FDTD) technique.
A switching device based on a-Si:H n-i-/spl delta/p-i-n stacked structure: modeling and characterization

A new two-terminal switching device based on an a-Si:H n-i-/spl delta/p-i-n symmetrical structure is investigated. The current through the device arises from thermionic emission of electrons over the triangular barrier lowered by the applied voltage. The key role of the thickness and of the doping level of the central /spl delta/p layer on the electrical behavior of the device is analyzed in detail by a numerical model. The current-voltage characteristic of an optimized device exhibits an ON/OFF current ratio, taken at 3 and 1 V, respectively, of six orders of magnitude with a nonlinearity factor /spl eta/=3.7.
Design and Implementation of a Hybrid Architecture Big Data Platform for Catchment Water Resource Spatial Temporal Management and Control

The management and protection of catchment water resource are effective measures to promote the harmonious coexistence of human and nature, and accelerate the construction of ecological civilization. Effective storage, management, and retrieval of large spatial temporal data in catchment water resource are facing enormous challenges. At the same time, higher requirements are put forward for data concurrent access support capability and security reliability. Therefore, it is urgent to carry out research on intelligent management and control of large spatial temporal data in catchment water resource. This paper develops a hybrid architecture storage and retrieval system for large spatial temporal data of catchment water resource, which solves the problems of efficient storage and retrieval of massive multi-source heterogeneous data and concurrent access support. Combined with the technical specifications of water resources and geographic information related countries and industries, the existing water-related management system is migrated and integrated by using the “one-source-one-repository” model, avoiding repeated collection and storage of observation data, improving data consistency, and facilitating data sharing among various subsystems. HBase-based tile pyramid storage is used to implement fast visual display and query of data. Metadata model based on MongoDB document model is used to simplify metadata description. At the same time, the Elasticsearch search engine is used to build metadata full-text index, which provides multiple matching methods such as exact matching, fuzzy search, and range query. Spatial vector feature data storage model is established based on GeoJSON and MongoDB, build spatial index, design auxiliary index to accelerate data query and filtering, design sharing strategy in shared replication cluster, balance the contradiction between data distribution and query efficiency.
Case Report on Hydatid Cysts with Hydropnemonothorax

Introduction: Hydatid disease is caused by a parasite infection induced by an echinococcus tapeworm. The hydatid cyst is one recognized cause of liver mass. It is a significant pathogenic, zoonotic, and parasitic illness (acquired from animals) of humans after consumption of tapeworm eggs produced in the faeces of infected dogs. Hydatid disease is a serious endemic health concern in various regions of the world. Cystic hydatid disease is most often associated with the liver (50–70%), although it can also affect the lung, spleen, kidney, bones, and brain. A hydropneumothorax occurs gradually. Case Presentation: A 35-year-old Man was taken to the Acharya Vinoba Bhave Rural Hospital with the chief complaint of abdominal discomfort, breathlessness (dyspnea) right side pain for 2 days. Approximately to the peritoneal cavity of the right chest by a hydatid cyst in the subscapular posterior part of the right lobe of the liver. For minimal ascites, a contrast study was conducted, revealing a multi-located hypodense cystic lesion spread across the abdomen was recognized as sign of hydatid disease. Conclusion: In a patient with a hydatid disease, physical and psychological therapy should be put together. In this study, we primarily focus on professional management and outstanding nursing care, which may give the comprehensive care that hydatid cyst requires. The complete health care team works together to assist the patient to restore his or her prior level of independence and happiness after a full recovery.
Congenital Micropenis: Etiology And Management

Abstract In the newborn, penile length is determined by a number of androgen dependent and independent factors. The current literature suggests that there are interracial differences in stretched penile length in the newborn and although congenital micropenis should be defined as a stretched penile length of less than 2.5 SDS of the mean for the corresponding population and gestation, a pragmatic approach would be to evaluate all boys with a stretched penile length below 2 cm, as congenital micropenis can be a marker for a wide range of endocrine conditions. However, it remains unclear as to whether the state of micropenis, itself, is associated with any long-term consequences. There is a lack of systematic studies comparing the impact of different therapeutic options on long-term outcomes, in terms of genital appearance, quality of life, and sexual satisfaction. To date, research has been hampered by a small sample size and inclusion of a wide range of heterogeneous diagnoses; for these reasons, condition-specific outcomes have been difficult to compare between studies. Lastly, there is a need for a greater collaborative effort in collecting standardized data so that all real-world or experimental interventions performed at an early age can be studied systematically into adulthood.
Dose-Dependent Effects of a Novel Selective EP4 Prostaglandin Receptor Agonist on Treatment of Critical Size Femoral Bone Defects in a Rat Model

Difficulties in treating pseudarthrosis and critical bone defects are still evident in physicians’ clinical routines. Bone morphogenetic protein 2 (BMP-2) has shown promising osteoinductive results but also considerable side effects, not unexpected given that it is a morphogen. Thus, the bone regenerative potential of the novel selective, non-morphogenic EP4 prostaglandin receptor agonist KMN-159 was investigated in this study. Therefore, mineralized collagen type-1 matrices were loaded with different amounts of BMP-2 or KMN-159 and implanted into a 5 mm critical-sized femoral defect in rats. After 12 weeks of observation, micro-computed tomography scans were performed to analyze the newly formed bone volume (BV) and bone mineral density (BMD). Histological analysis was performed to evaluate the degree of defect healing and the number of vessels, osteoclasts, and osteoblasts. Data were evaluated using Kruskal-Wallis followed by Dunn’s post hoc test. As expected, animals treated with BMP-2, the positive control for this model, showed a high amount of newly formed BV as well as bone healing. For KMN-159, a dose-dependent effect on bone regeneration could be observed up to a dose optimum, demonstrating that this non-morphogenic mechanism of action can stimulate bone formation in this model system.
