Abstract

We present an analysis of the solar corona visual spectrum, captured during the total solar eclipse of 21 August 2017, in Salem, Oregon USA. The eclipse took place about 2 years before the solar minimum of the 25th solar cycle, that occurred on 2019/2020. The spectra were captured by two slitless spectrographs with different dispersions and include the two principal coronal emission lines Fe XIV and Fe X. Following the continuum subtraction of the K-corona, the very faint coronal emission line of Ar X 5533 A was detected. The slitless spectrograph also recorded the distribution of Ar X around the solar limb, which was compared to the distribution of the two principal ionized iron lines. A correlation between the distributions of Ar X and Fe XIV has been identified and an explanation is provided for the Ar X presence in the solar corona around the solar minimum periods. Simultaneous observations with the two-channel Lyot filter, tuned at the green and red coronal lines of iron, revealed different formations and structures that exist at the eastern solar limb, high in the corona and appearing at extended solar latitudes. Due to the moisture presence in the Earth's atmosphere, all obtained spectra during the solar eclipse contain also strong absorption lines of water vapor.

Abstract
Background
There is growing evidence that long non-coding RNA long iatrogenic non-protein-coding RNA p53-induced transcript (LINC-PINT) is highly expressed in cancer tissue and is associated with the prognosis of cancer patients. The present study systematically analyzed the prognostic significance of LINC-PINT expression in cancer patients.
Methods
We collected eligible studies through the PubMed, Embase, and Cochrane library searches until February 1, 2024. The prognostic significance of LINC-PINT expression was evaluated by conducting a meta-analysis.
Results
Eleven eligible studies with 2876 cancer patients were collected. The pooled results revealed that LINC-PINT expression was associated with favorable overall survival (OS) and disease-free survival (DFS) in cancer patients (for OS, hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.64–0.80, p < 0.001; for DFS, HR 0.70, 95% CI 0.60–0.82, p < 0.001).
Conclusion
LINC-PINT expression was associated with favorable OS and DFS, and it may serve as a valuable prognostic marker in cancer patients.

Abstract

Background
T-tube cholangiography and choledochoscopy are commonly employed techniques for assessing residual bile duct stones following biliary surgery. Further investigation is warranted to determine the utility of routine cholangiography prior to T-tube removal. It is imperative to explore the diagnostic efficacy of various examination methods for detecting residual calculi post-biliary surgery.
Methods
The clinical data of 287 patients who underwent T-tube angiography and choledochoscopy following choledochotomy and subsequent T-tube drainage at the Department of General Surgery, Xuanwu Hospital, Capital Medical University from 2017 to 2022 were retrospectively analyzed. All patients underwent both cholangiography and choledochoscopy six to eight weeks after laparoscopic cholecystectomy combined with common bile duct exploration and T-tube drainage surgery. The results of T-tube cholangiography and choledochoscopy for each patient were recorded, followed by analysis and comparison.
Results
Among the cohort of 287 patients, T-tube cholangiography revealed 38 cases of residual stones, which were subsequently confirmed by choledochoscopy in 29 cases. Conversely, among the remaining 249 patients who exhibited no evidence of residual stones on T-tube angiography, a single patient was later verified to have retained stones through choledochoscopy. The results of T-tube cholangiography and choledochoscopy showed no significant difference (P = 0.82), indicating a high level of agreement between the two methods (Kappa value: 0.70).
Conclusion
The simultaneous performance of T-tube cholangiography and choledochoscopy after biliary surgery is recommended to enhance the diagnostic accuracy of residual stones and reduce the incidence of bile duct stone remnants.
Spin orbit resonance cascade via core shell model. \Application to Mercury and Ganymede
Authors: Pinzari Gabriella , Scoppola Benedetto , Veglianti Matteo 
Published: February 2024

Abstract

We discuss a model describing the spin orbit resonance cascade. We assume that the primary has a two-layer (core-shell) structure: it is composed by a thin solid crust and an inner and heavier solid core that are interacting due to the presence of a fluid interface. We assume two sources of dissipation: a viscous one, depending on the relative angular velocity between core and crust and a tidal one, smaller than the first, due to the viscoelastic structure of the core. We show how these two sources of dissipation are needful for the capture in spin-orbit resonance. The crust and the core fall in resonance with different time scales if the viscous coupling between them is big enough. Finally, the tidal dissipation of the viscoelastic core, decreasing the eccentricity, brings the system out of the resonance in a third very long time scale. This mechanism of entry and exit from resonance ends in the 1 : 1 stable state.

Published: February 2024

Abstract
Purpose: Disruptive technologies (AI, IoT, etc) unlock new frontiers of data-centric innovation. This increases the computational needs, pushing more and more companies into the HPC space. However, although HPC is a key tool for processing and analysing the constantly growing volume of data across numerous application areas many companies remain reluctant to use HPC and move their HPC workloads to the cloud, which may be attributed to the inadequate understanding about HPC and its potential benefits, cost, security and performance aspects. At the same time, existing HPC training, mainly focus on the research and academic community, thus creating a gap in the provision of industrial HPC training and addressing the supercomputing knowledge skills of enterprises.
Methods: Towards this aim, this paper presents an example of “massively” co-created education and training HPC module, namely an HPC NOOC (Nano Open Online Course), targeting industrial learners. This open, agile co-creation approach incorporates key components of the European HPC ecosystem and beyond, aiming to offer a paradigm for success in the democratisation of HPC knowledge, and the co-creation of educational value aiming to reach a wide impact (i.e., educational, technological, innovation, economic impact, etc).
Results: The proposed HPC NOOC has been designed in an agile format so as to enable its ongoing evolution and expansion across emerging themes and indicative success stories across Europe and the world.
Conclusion: Acknowledging the importance of HPC as a strategic investment for Europe and the world, this paper, aims to contribute to the democratisation of HPC training for industry and narrowing the gap between HPC adoption for micro, small and medium sized enterprises is important in order to reap the benefits of HPC innovations.
Radiation Health Risk to Human Scavengers at Refuse Dumpsites in Calabar, Nigeria
Authors: Inyang Samuel O. , Ekong Isaac 
Published: February 2024

Abstract
Introduction
Refused dumpsites are known to be associated with enhanced level of ionizing radiation depending on the items that constitute the refuse. Exposure to chronic levels of exposure from these refuse dumpsites could result in severe health risk.
Materials and Methods
Calabar was divided into three sections depending on the location for ease of data collection. The dumpsites in each section were identified by their geographical coordinates using geographical positioning system (GPS) device. Exposures were measured using an exposure meter in µSv/h and converted to annual effective dose rate in mSv/yr. The effective dose rate values were used in evaluating the cancer incidence and mortality for male and female using conversion factors in BEIR VII.
Results
The annual effective dose rates for the waste dumpsites in Calabar ranged from 0.15 – 0.36 mSv/yr, with one dumpsite in Section C having the highest value annual effective dose rate of 0.36 mSv/yr. The corresponding observed maximum values of cancer incidence for male and female respectively were 110 and 154 persons per 100,000 persons while the cancer mortality for male and female were respectively 61 and 86 persons per 100,000 persons.
Conclusion
The study shows enhanced levels of ionizing radiation around waste dumpsites in Calabar. The effective dose rates were lower than the established occupational effective dose. The cancer incidence and mortality evaluated for males and females were low. However, there is need to control the activities of scavengers around the waste dump to further minimize the cancer risk.

Abstract

Purpose
The study aimed to characterize the erythrocytic profile in patients with Cushing’s syndrome (CS) versus controls from the normal population according to etiology, sex, presence of diabetes mellitus (DM) and hypercortisolemia remission status.
Methods
This retrospective cohort analysis compared erythrocytic parameters between patients with CS of pituitary (CD) and adrenal (aCS) etiology and age, sex, body mass index (BMI) and socioeconomic status-matched controls in a 1:5 ratio. Laboratory values at baseline were calculated as mean values during the year preceding CS diagnosis, and over one year thereafter.
Results
The cohort included 397 CS patients (68.26% female; mean age 51.11 ± 16.85 years) and 1970 controls. Patients with CS had significantly higher baseline median levels of hemoglobin (Hgb) (13.70 g/dL vs. 13.12 g/dL [p < 0.0001]) and hematocrit (Hct) (41.64% vs. 39.80% [p < 0.0001]) compared to controls. These differences were observed for both CD and aCS and for both sexes. Patients who attained remission had Hgb and Hct levels comparable to controls (13.20 g/dL and 40.08% in patients with CD and aCS vs. 13.20 g/dL and 39.98% in controls). Meanwhile, those with persistent/recurrent disease maintained elevated levels. Patients with comorbid DM had similar Hgb but higher Hct (p = 0.0419), while patients without DM showed elevated erythrocytic values compared to controls (p < 0.0001).
Conclusion
Our data illustrates that erythrocytic parameters are directly influenced by glucocorticoid excess as Hgb and Hct are higher in patients with CS, and normalize after remission. We have identified the influence of DM on erythrocytic parameters in patients with CS for the first time.
A Multiple Linear Regression Forecast of PM10 Air Contamination
Authors: Kumar Lokesh , Kumar Gaurav 
Published: February 2024

Abstract
Proper estimation of air pollutants, especially Particulate Matter (PM), is essential for convincing and successful air quality control. A wide range of factors impact PM prediction, and in addition to guarantee the most reliable forecasts, it is imperative to integrate the most pertinent input variables. In order to choose the most relevant input and output variables for an air pollution model, this study uses the multiple linear regression approach. In this work, the concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2), and the air quality index (AQI) are used to determine the concentration of PM10.
Decomposing the AIA~304 channel into its cool and hot components

Published: February 2024

Abstract

The AIA~304 channel on board the \textit{Solar Dynamics Observatory} (SDO) offers a unique view of low transition region (TR) plasma emitting in the He II 304 ˚A line. However, when observing off-limb, the emission of the (small) cool structures in the solar atmosphere (such as spicules, coronal rain and prominence material) can be of the same order as the surrounding hot coronal emission from other spectral lines included in the 304 passband, particularly over active regions. In this paper we investigate three methods based on temperature and morphology that are able to distinguish the cool and hot emission within the 304 passband. The methods are based on the Differential Emission Measure (DEM), a linear decomposition of the AIA response functions (RFit) and the Blind Source Separation (BSS) technique. All three methods are found to produce satisfactory results in both quiescent and flaring conditions, largely removing the diffuse corona and leading to images with cool material off-limb in sharp contrast with the background. We compare our results with co-aligned IRIS data in the SJI 1400 and 2796 channels, and find the RFit method to best match the quantity and evolution of the cool material detected with \textit{IRIS}. Some differences can appear due to plasma emitting in the log T = 5.1 − 5.5 temperature range, particularly during the catastrophic cooling stage prior to rain appearance during flares. These methods are in principle applicable to any passband from any instrument suffering from similar cool and hot emission ambiguity as long as there is good coverage of the hot temperature range.

Abstract

Patients with lung cancer have a high incidence of tumor recurrence even after curative surgical resection. Some reports indicated that immunosuppressive cells induced by surgical stress could contribute to tumor recurrence after surgery; however, the underlying mechanisms are not fully understood. In this study, we found that increased postoperative blood monocytes served as a risk factor for tumor recurrence in 192 patients with non-small cell lung cancer (NSCLC). We established the lung cancer recurrent mouse model after tumor resection and showed that the surgical stress immediately increased the level of serum monocyte chemoattractant protein-1 (MCP-1), which subsequently increased blood monocytes. These blood monocytes were rapidly recruited into distant micrometastases and became tumor growth-promoting TAMs (tumor associated macrophages). Furthermore, even after the blood MCP-1 and monocytes decreased enough 72 hours after tumor resection, TAMs in micrometastases remained rich because the MCP-1 secreted by micrometastases themselves continued to recruit monocytes around the tumor. Consequently, tumor resection triggered the outgrowth of distant metastases via the MCP-1–Monocyte–TAM axis. When we administered the MCP-1 inhibitor to the lung cancer recurrent model mice, blood monocytes decreased after tumor resection, and TAMs in micrometastases also dramatically decreased. Finally, peri- and postoperative treatment with the MCP-1 inhibitor suppressed distant metastases after surgery. Targeting the MCP-1–Monocyte–TAM axis may inhibit surgical stress-induced NSCLC recurrence by attenuating postoperative immunosuppressive monocytes in micrometastases.

Abstract

Background: Spatial repellents can provide personal and household protection against biting vector mosquitoes by volatising repellents into the air within a given area. Mosquito ShieldTM is a transfluthrin passive emanator undergoing evaluation for malaria control. Studies evaluating its entomological impact against different local malaria vector populations would help guide its deployment in endemic countries.
Methods: We performed a two-arm single-blinded small-scale household randomised entomological trial to assess the impact of Mosquito ShieldTM on the human landing rate of wild pyrethroid-resistant Anopheles gambiae sl vector mosquitoes in houses in the Ganhoua village of the Zakpota District of central Benin. From a total of 30 houses, 15 were randomly allocated to receive Mosquito ShieldTM while the remainder received a placebo product. The trial lasted through the life of the Mosquito ShieldTM product (32 days). Mosquito sampling was performed by human landing catches at baseline and at 6 timepoints post-intervention (days 0-1, 7-8, 14-15, 21-22, 28-29 and 31-32). Collections were performed for 2 days at each sampling time point. WHO cylinder bioassays were conducted during the trial with F1, An gambiae sl mosquitoes that emerged from larvae from the study area to assess the intensity of resistance to pyrethroids in the wild vector population.
Findings: The vector population in the study area showed a high intensity of resistance to pyrethroids. Baseline An gambiae sl human landing rates were similar in houses in both study arms before product application (11.53/person/night vs 11.67/person/night, p>0.05). A total of 5736 mosquitoes were collected in the placebo control arm and 3862 in the Mosquito ShieldTM arm post-intervention. Overall An gambiae sl human landing rates post-intervention were significantly lower in houses in the Mosquito ShieldTM arm 18.13/person/night) compared to the houses in the placebo control arm (26.84/person/night, IRR=0.658, p<0.001). Over the lifespan of the product, Mosquito ShieldTM provided a significant protective efficacy of 34.2% (22.1%-44.4%, p<0.001) against wild pyrethroid-resistant An gambiae s.l. vectors compared to the placebo. Human landing rates of other nuisance vector mosquito species (Culex and Mansonia) were also reduced in houses treated with Mosquito ShieldTM compared to the placebo.
Conclusion: Mosquito ShieldTM, a transfluthrin passive emanator, provided significant protection against pyrethroid-resistant malaria vectors to households in Benin. The spatial repellent shows potential to reduce malaria transmission by pyrethroid-resistant An gambiae sl vector mosquitoes and cover gaps in malaria control when deployed to complement existing vector control interventions.

Published: February 2024

Abstract
Commercial phosphorous light emitting diodes (PLEDs) have many impairments such as slow response, low bandwidth (BW), and signal attenuation which limit the performance of VLC systems. In our previous work, we proposed an efficient 16 QAM link integrating an optical preamplifier with a PLED. We successfully demonstrated the transmission of 0.5 Gbps over a VLC link of 7 m range. In this work, we have further modified the 16 QAM system and upgraded it to 16 QAM-OFDM employing an optical preamplifier and a bandpass filter (BPF) after the photodetector. The effect of the preamplifier gain and the BPF bandwidth on the performance of the 16 QAM-OFDM system have been investigated. The results showed that a BPF with BW of 375 MHz offers an optimum performance of the system at a data rate of 1 Gbps. A minimum Log of BER of -3.515 is achieved.
The effect of the optical preamplifier gain on the link performance is also investigated. When the gain is 15 dB, the distance is restricted to 1.5 m only when considered SFEC limit. However, when the gain is 20 dB a maximum distance up to 3 m is achieved while considering SFEC limit.\\ The BPF optimized bandwidth of 375 MHz, and the preamplifier gain of 20 dB are used successfully to transmit a data rate of 6 Gbps for distance of 1.5 m while considering the SFEC limit. When the data rate is incresead to 7 Gbps, the link range is abruptly decreased to 0.5 m.

Published: February 2024

Abstract
Background
There is no clear negative impact of medication overuse headache (MOH) on quality of life (QoL).
Objective
The aim of this study was to identify clinical and headache-related parameters that directly affect the HRQoL of MOH patients.
Patients and Methods:
A total of 183 patients (111 men and 72 women) first diagnosed with MOH and 81 healthy subjects (22 men and 59 women) in the control group (CG) were enrolled in this study. The age of the study subjects ranged from 18 to 71 years. HRQoL was assessed using the Short Form-36 (SF-36), which includes the physical composite score (PCS), mental composite score (MCS) and total score (TS).
Results
The HRQoL of all patients (PCS, MCS, TS) was lower in the MOH than in the CG (p < 0.001). In the MOH, depression itself was a risk factor for all aspects of HRQoL according to the PCS (B = -0.70, 95% CI -1.32–0.08, p = 0.027); for the MCS (B = -0.71, 95% CI -1.14 - − 0.29, p = 0.001); and for the TS (B = -0.69, 95% CI -1.16 - − 0.22, p = 0.005)), with female sex being an associated risk factor only for PCS (B = -15.47, 95% CI -26.79 - − 4.14, p = 0.008). The results did not reveal a predictive role of anxiety, stress, or ruminative style of thinking for HRQoL in MOH patients (p > 0.05).
Conclusions
Screening for depression among MOH patients and treatment could be useful for improving their HRQoL.
