Effects of solar evolution on finite acquisition time of Fabry–Perot interferometers in high resolution solar physics
Authors: Schlichenmaier R. , Pitters D. , Borrero J. M. , Schubert M. 
Published: November 2022

Context. The Visible Tunable Filter (VTF) imaging spectropolarimeter will be operated at the Daniel K. Inouye Solar Telescope (DKIST) in Hawaii. Due to its capability in resolving dynamic fine structure of smaller than 0.05 arcsec, the finite acquisition time of typically 11 s affects the measurement process and potentially causes errors in deduced physical parameters.
Aims. We estimate these errors and investigate ways of minimising them.
Methods. We mimicked the solar surface using a magnetohydrodynamic simulation with a spatially averaged vertical field strength of 200 G. We simulated the measurement process scanning through successive wavelength points with a temporal cadence of 1 s. We synthesised Fe 1617.3 nm for corresponding snapshots. In addition to the classical composition of the line profile, we introduce a novel method where the intensity in each wavelength point is normalised using the simultaneous continuum intensity, and then multiplied by the temporal mean of the continuum intensity. Milne-Eddington inversions were used to infer the line-of-sight velocity, vlos, and the vertical (longitudinal) component of the magnetic field, Blos.
Results. We quantify systematic errors, defining the temporal average of the simulation during the measurement as the truth. We find that with the classical composition of the line profiles, errors exceed the sensitivity for vlos, and in filigree regions also for Blos. The novel method that includes normalisation reduces the measurement errors in all cases. Spatial binning without reducing the acquisition time decreases the measurement error slightly.
Conclusions. The evolutionary timescale in inter-granular lanes, in particular in areas with magnetic features (filigree), is shorter than the timescale within granules. Hence, depending on the science objective, fewer accumulations could be used for strong magnetic field in inter-granular lanes and more accumulations could be used for the weak granular magnetic fields. As a key result of this investigation, we suggest including the novel method of normalisation in corresponding data pipelines.
Intramural Jejunal Hematoma Causing Intermittent Bowel Obstruction—A Rare Manifestation of Warfarin Toxicity
Authors: Patil Arun S. , Shriya Shriya , Dhimole Nikhil , More Jalbaji 
Published: November 2022

AbstractPatients with thromboembolic disorders are commonly on anticoagulants; hence, they are susceptible to bleeding episodes such as ecchymosis, gingival, subconjunctival bleeding, and rarely can have intramural hematoma of small bowel causing patient to present with intestinal obstruction. It is a rare cause of mechanical bowel obstruction requiring a nonsurgical management.Our patient was a 55-year-old male, a known case of thromboembolism on warfarin medication, presented with abdominal pain and vomiting. Patient's laboratory reports reflected anemia and deranged coagulation profile with prothrombin time and international normalized ratio, both being elevated. Intramural hematoma of jejunum was diagnosed by abdominal contrast-enhanced computed tomography. Conservative management was done, warfarin was stopped and vitamin K was administered. Patient received fresh frozen plasma and packed cell blood.It is important to suspect warfarin toxicity in patients on the medication who come with such presentation to avoid surgical management, which could be catastrophic due to excessive bleeding. It is important for regular monitoring of coagulation profile of such patients and to reduce prescribing other medications that can interact with warfarin. It is worth noting that novel oral anticoagulants, such as dabigatran and rivaroxaban, are associated with fewer side effects and do not require close laboratory monitoring.
Rapunzel Syndrome: A Case of Trichobezoar with Small Bowel Complications
Authors: Narra Ramakrishna , Guntamukkala Anusha , Rao Chanda Bhaskara , Begum Tanveer 
Published: November 2022

Abstract
Introduction Rapunzel syndrome is characterized by a large trichobezoar in the stomach with a tail extending beyond the pylorus into the small bowel, causing mechanical obstruction of the small bowel. A 7-year-old girl presented to the emergency room with severe epigastric pain. Computed tomography suggested trichobezoar causing jejuno-jejunal intussusceptions, bowel wall thickening, and dilated small bowel loops proximal to the obstruction. On laparotomy, two concealed perforations were noted at the duodenojejunal (DJ) junction and 40 cm distal to the DJ junction. An enterotomy incision was given at the antimesenteric border of the distal jejunal perforation site, and the mass was successfully extracted. Primary repair was done at the DJ perforation site, and resection was followed by an end-to-end anastomosis at the distal jejunal perforation site. Surgery confirmed a complex mass of tangled hair within the gastric cavity with a tail extending into the pylorus of the stomach and small intestine, consistent with trichobezoar.
Conclusion Computed tomography is superior to other radiological imaging modalities for diagnosing trichobezoars as it helps diagnose and demonstrate mechanical bowel complications.
Exploring Effects of the HEP (Homeostasis-Enrichment-Plasticity) Approach as a Comprehensive Therapy Intervention for an Infant with Cerebral Palsy: A Case Report
Authors: Balıkcı Aymen 
Published: November 2022

AbstractCerebral palsy (CP) is a common non-progressive neurodevelopmental disorder which causes developmental disabilities in children. Varied interventions for CP exist to address medical and physical needs but with limited effectiveness evidence. Environmental enrichment (EE) is an animal model intervention for many neurodevelopmental disorders, including CP, with considerable positive effects. This case report defines the Homeostasis-Enrichment-Plasticity (HEP) approach, which is based upon principles of EE and ecological theories of development and describes its use to promote the developmental and functional skills of an infant with CP. Parent interviews and assessment data were completed before and after intervention. For the interested parameters data was gathered by developmental history, systematic observation of behaviors in the clinical setting and at home, Beck Anxiety Inventory (BAI), Infant-Toddler Symptom Checklist, the Sensory Proﬁle Infant/Toddler, Peabody Developmental Motor Scales-2, Gross Motor Function Measurement-88 (GMFM-88), the Gross Motor Function Classification System (GMFCS), and Pediatric Evaluation of Disability Inventory (PEDI). The HEP approach intervention was implemented one time per week for 12 months. Following the HEP approach intervention, self-regulation and sensory processing scores improved. GMFM-88 total score improved from 45/264 to 123/264. The Peabody found all gross motor (54–110), fine motor (65–117), and total motor quotient (119–227) scores improved after intervention. Post-intervention observations showed obvious gross motor progress with movement from GMFCS Level IV to Level I. Performance on the Functional Skills Scales and Caregiver Assistance Scales of PEDI also demonstrated notable improvements. BAI scores revealed low anxiety scores for both the mother (13/63 points) and father (14/63) before intervention. These scores did not change after intervention. A definition and detailed description of the HEP approach intervention is presented here for the first time. The case report demonstrated preliminary evidence for the effectiveness of the HEP approach on self-regulation, sensory processing, motor development, functional skills, and caregiver assistance with an infant with CP. Additional studies are needed to validate the findings.

Published: November 2022

AbstractBackground Spigelian hernias are a rare type of lateral ventral abdominal hernia and their content can include any of the intra-abdominal organs. Many cases have described the presence of a variety of abdominal organs in Spigelian hernias, but only few cases report the presence of an incarcerated appendicitis. Imaging is an important step in the diagnosis to avoid the lack of knowledge in such cases. Surgical treatment can be through open or laparoscopic approach, with or without using a mesh according to the size of the defect.Case Report We report a case of an 82-year-old patient who presented with an acute appendicitis with peri-appendicular abscess strangulated in a right Spigelian hernia. The patient was successfully treated by a laparoscopic appendectomy, a surgical drainage of the abscess, and direct muscle approximation without using of mesh due to inflammation.Conclusion Spigelian hernias with acute appendicitis in their content are a very rare condition. Clinical diagnosis is usually difficult and challenging and computed tomography scan is the imaging modality of choice. The treatment is surgical.

Published: November 2022

AbstractGallstones in western countries are primarily composed of cholesterol. However, mixed or pigment stones, which contain a higher proportion of bilirubin, are more frequently seen in developing nations and Asia than in western countries. Abdominal and shoulder tip pains (STPs) are common complaints following the standard laparoscopic cholecystectomy procedure. To date, all pain management modalities have proven variable outcomes. This prospective randomized study included 82 patients who underwent elective laparoscopic cholecystectomy. The control group received 20 mL of normal saline, whereas the study group received a 20-mL instillation of 0.5% bupivacaine at the gallbladder bed after surgical resection. The Visual Analog Scale (VAS) was used to analyze abdominal pain and STP. The mean age ranged from 20 to 80 years. Abdominal VAS at 6, 12, 18, 24, 30, 36, and 48 hours were statistically insignificant. The majority were discharged on postoperative day 1 (32 studies, 37 control). Follow-up VAS after 1 week for STP VAS and abdominal pain VAS in both groups were statistically insignificant. Even with small numbers of a well-conducted randomized trial, we demonstrated that bupivacaine irrigation at the gallbladder bedpost laparoscopic cholecystectomy does not affect pain relief.

AbstractEndotracheal intubation is associated with an increased risk of cardiorespiratory arrest. Various factors modulate the risk of peri-intubation cardiorespiratory arrest. The primary objective of this study was to determine the risk of peri-intubation cardiorespiratory arrest in pediatric patients in a hospital setting, and the secondary objective was to determine the effect of various factors on the peri-intubation cardiorespiratory arrest risk. A systematic review was performed to identify eligible manuscripts. Studies were deemed appropriate if they included pediatric patients in a hospital setting not exclusively intubated for an indication of cardiorespiratory arrest. Data were extracted from studies deemed eligible for inclusion. A pooled risk of cardiorespiratory arrest was determined. A Bayesian linear regression was conducted to model the risk of cardiorespiratory arrest. All data used in this were study-level data. A total of 11 studies with 14,424 intubations were included in the final analyses. The setting for six (54.5%) studies was the emergency department. The baseline adjusted risk for peri-intubation cardiorespiratory arrest in pediatric patients was 3.78%. The mean coefficient for a respiratory indication for intubation was −0.06, indicating that a respiratory indication for intubation reduced the per-intubation cardiorespiratory arrest risk by 0.06%. The mean coefficient for use of ketamine was 0.07, the mean coefficient for use of a benzodiazepine was −0.14, the mean coefficient for use of a vagolytic was −0.01, and the mean coefficient for use of neuromuscular blockade was −0.40. Pediatric patients during the peri-intubation period have the risk of developing cardiorespiratory arrest. The pooled findings demonstrate associations that seem to highlight the importance of maintaining adequate systemic oxygen delivery to limit this risk.
Single-family courtyard houses in Poland: conditions and perspectives for development based on the example of Krakow
Authors: Homiński Bartłomiej 
Published: November 2022

AbstractSingle-family courtyard houses, with spaces oriented towards an internal, private patio, became popular in Western Europe in the 1960s and 1970s. In Poland, courtyard developments are infrequent and were mostly built in the 1970s and 1980s. This study aims to improve our understanding of their low popularity. Poles seem to prefer traditional housing solutions, clearly favouring detached houses, considered to provide the most comfort, privacy, and safety. More than half of the country’s population lives in such buildings, considerably more than the European average. This study suggests that planning conditions along with land registry patterns are fundamental barriers to the development of courtyard housing. In practice, they eliminate the potential for building new complexes of this type. In a broader context, planning conditions reinforce the dominance of traditional, less dense forms of single-family development, primarily those of detached development. This paper posits that there are no favourable conditions for new courtyard housing developments if they are to be based on market fundamentals. Courtyard housing could, however, as in the period of its inception and popularity, become part of an extensive housing experiment, for instance, in national or regional pilot projects, and contribute to animation and progression in housing development.

Published: November 2022

Graphene and its derivatives, due to their two-dimensional carbon nanostructures, have provided new opportunities to fortify organic dye-based photovoltaic and photocatalytic assemblies. In this article, we employed organic dyes Rhodamine B (RdB) and graphene oxide (GO) [or reduced graphene oxide (RGO)] to assemble the composite materials RdB–GO and RdB–RGO. It was found that both GO and RGO could strongly quench the fluorescence (FL) intensity of RdB. The mechanisms of FL quenching in both RdB–GO and RdB–RGO have been investigated by using femtosecond fluorescence up-conversion and transient absorption spectroscopy. When RdB was anchored on the GO (or RGO) surface, the solvent relaxation component 3.1 ps of pure RdB disappeared; instead, the ultrafast excited state electron transfer process (1–2ps) in RdB-GO and RdB-RGO was found and originated from the LUMO of RdB to the conduction band of GO (or RGO). We further reveal that the energy level change caused by GO reduction makes the energy levels of RGO closer to those of RdB, resulting in the electron transfer being more effective in RdB–RGO. Therefore, the RdB–RGO composite materials may have higher application values for dye-sensitized solar cells.
Impact of the new 12C+12C reaction rate on presupernova nucleosynthesis*
Authors: Xin Wenyu , Nomoto Ken’ichi , Zhao Gang , Wu Wenbo 
Published: November 2022

Abstract
The 12C+12C reaction rate plays an essential role in stellar evolution and nucleosynthesis. Nevertheless, the uncertainties of this reaction rate are still large. We calculate a series of stellar evolution models with the near solar abundance from the zero-age main-sequence through presupernova stages for initial masses of 20 M

to 40 M

. The 12C+12C reaction rates from two different studies are used in our investigation. One is the rate obtained using the Trojan Horse Method (THM) by Tumino et al. [Nature 557(7707), 687 (2018)], and the other was obtained by Mukhamedzhanov et al. [Physical Review C 99(6), 064618 (2019)] (Muk19). Then, comparisons of the nucleosynthesis and presupernova isotopic abundances are conducted. In particular, we find that in the C burning shell, models with the THM produce a smaller amount of 23Na and some neutron-rich isotopes than Muk19. The difference in the abundance ratios of Na/Mg, S/Mg, Ar/Mg, and K/Mg between the two models are apparent. We compare Na/Mg obtained from our theoretical presupernovae models with Na/Mg in stellar atmospheres observed with high-resolution spectra as well as from the latest galactic chemical evolution model. Although Na/Mg obtained using the THM is within 2σ of the observed stellar ratio, the theoretical uncertainty on Na/Mg introduced by the uncertainty of the 12C+12C reaction rate is almost equivalent to the standard deviation of astronomical observations. Therefore, a more accurate 12C+12C reaction rate is crucial.

Published: November 2022

Abstract

Objective. The use of deep learning for electroencephalography (EEG) classification tasks has been rapidly growing in the last years, yet its application has been limited by the relatively small size of EEG datasets. Data augmentation, which consists in artificially increasing the size of the dataset during training, can be employed to alleviate this problem. While a few augmentation transformations for EEG data have been proposed in the literature, their positive impact on performance is often evaluated on a single dataset and compared to one or two competing augmentation methods. This work proposes to better validate the existing data augmentation approaches through a unified and exhaustive analysis. Approach. We compare quantitatively 13 different augmentations with two different predictive tasks, datasets and models, using three different types of experiments. Main results. We demonstrate that employing the adequate data augmentations can bring up to 45% accuracy improvements in low data regimes compared to the same model trained without any augmentation. Our experiments also show that there is no single best augmentation strategy, as the good augmentations differ on each task. Significance. Our results highlight the best data augmentations to consider for sleep stage classification and motor imagery brain–computer interfaces. More broadly, it demonstrates that EEG classification tasks benefit from adequate data augmentation.
Dynamic stability study of velocity time lag feedback control of axially moving viscoelastic beams
Authors: Yan ChangHao , Tang YouQi , Wang Bo 
Published: November 2022

Abstract
In engineering fields, such as in deep space processing, paper industry, steel making industry and aerospace field etc., transverse vibration caused by axial motion not only affects the service life of the structure, but also may cause major accidents. Therefore, it is necessary to control the vibration. However, time lag is unavoidable in the process of vibration control because of the time lag in the signal transmission. On the one hand, it not only affects the robustness of the system and produces a very complex dynamic response; on the other hand, the amount of time lag can be used as a parameter to control the vibration. In this paper, a new model of time lag feedback is established, considering the effect of mechanical properties of the linear vibration model of an axially moving viscoelastic beam. The direct multi-scale analysis is applied to analyze the parameter stability of the beam with and without the addition of time lag feedback control model. The subharmonic parameters are obtained by solvability conditions and the Routh-Hurwitz criterion.

Abstract
Combined with the operation specification of building tower cranes, the three-dimensional path planning technology of tower cranes and the optimization of path points are studied. The improved RRT-Connect algorithm is proposed. By introducing heuristic information in the path search, the path search efficiency and quality of the algorithm are improved. By eliminating invalid points in the path, the control burden of tower crane is reduced, and the optimized lifting point movement path is transformed into tower crane joint movement, and finally the calculation result is uploaded to PLC through LAN. The running trajectory of the tower crane lifting point is visually displayed in the scene model, and the validity and safety of the path are verified. The real tower crane is controlled. The operation is completed and the automatic driving of the tower crane is realized.

Published: November 2022

Abstract
The roller brush cleaning path of the gantry reciprocating automatic car washing machine is the key to determining the quality of the car wash. For the issue that the traditional method cannot accurately and reliably calculate the roller path, a rolling brush path planning scheme combined with fractional differential algorithm is proposed. By analysing the working form of the car washing machine and the appearance characteristics of the car, a multi-view car detection system is designed, and the car images are collected by using multiple cameras. The possibility of the path of each roller brush of the car washing machine is extracted from the contour information, and the contour curve is converted into the roller brush path in the form of coordinate points through software. Finally, the actual size of the car to be washed is calculated by the multi-view camera, and the average error between the calculation result and the actual result is 2.63%, which meets the operating conditions of the gantry reciprocating automatic car washing machine.
