Time-Restricted Feeding Could Not Reduce Rainbow Trout Lipid Deposition Induced by Artificial Night Light

Artificial night light (ALAN) could lead to circadian rhythm disorders and disrupt normal lipid metabolism, while time-restricted feeding (TRF) could maintain metabolic homeostasis. In mammals, TRF has been demonstrated to have extraordinary effects on the metabolic regulation caused by circadian rhythm disorders, but studies in lower vertebrates such as fish are still scarce. In this study, the impacts of ALAN on the body composition and lipid metabolism of juvenile rainbow trout were investigated by continuous light (LL) exposure as well as whether TRF could alleviate the negative effects of LL. The results showed that LL upregulated the expression of lipid synthesis (fas and srebp-1c) genes and suppressed the expression of lipid lipolysis (pparβ, cpt-1a, and lpl) genes in the liver, finally promoting lipid accumulation in juvenile rainbow trout. However, LL downregulated the expression of genes (Δ6-fad, Δ9-fad, elovl2, and elovl5) related to long-chain polyunsaturated fatty acid (LC-PUFA) synthesis, resulting in a significant decrease in the proportion of LC-PUFA in the dorsal muscle. In serum, LL led to a decrease in glucose (Glu) levels and an increase in triglyceride (TG) and high-density lipoprotein cholesterol (H-DLC) levels. On the other hand, TRF (mid-dark stage feeding (D)) and mid-light stage feeding (L)) upregulated the expression of both the lipid synthesis (srebp-1c and pparγ), lipolysis (pparα, pparβ, and cpt-1a), and lipid transport (cd36/fat and fatp-1) genes, finally increasing the whole-body lipid, liver protein, and lipid content. Meanwhile, TRF (D and L groups) increased the proportion of polyunsaturated fatty acid (PUFA) and LC-PUFA in serum. In contrast, random feeding (R group) increased the serum Glu levels and decreased TG, total cholesterol (T-CHO), and H-DLC levels, suggesting stress and poor nutritional status. In conclusion, ALAN led to lipid accumulation and a significant decrease in muscle LC-PUFA proportion, and TRF failed to rescue these negative effects.
Negotiating Stigma: Narratives of Displaced Children of the Kuki–Naga Ethnic Conf lict

The Kuki–Naga ethnic conflict of the nineties marked a period of violence and displacement of large number of people. While the literature of this conflict expound the causes and spectacle nature of violence, the less visible impact, including the challenges of displacement and poverty induced by the separation from home, are always ignored. Through in-depth interviews among Kuki youth with childhood experiences of the violence and displacement, this article is an attempt to understand the harsh realities of displaced survivors of the violence and the everyday challenges as they began to rebuild their lives. Childhood memories of participants in the study reveal that stigmatisation of displaced persons imposed a strong degree of obstacle to their adjustment with the difficult transformation imposed by violence and displacement. Against this continuing threat to their daily experiences, this article argues that a strong sense of resilience can be adopted through inter-generational transmission of memories.
Detection of X-ray emission from galaxies inside and towards the nearby voids

We searched for X-ray emission from the 665 galaxies inside and towards the nearby voids by analyzing the ROSAT All-Sky Survey (RASS) data as well as the ROSAT pointed observations (PSPC). As a result we have detected six X-ray emitting galaxies. Two (UGC 10205 and NGC 7509) are in the high density region in the local void, three (UGC 749, MCG +11-10-073, and Mrk 464) are towards the nearby voids, and UGC 32 is located in the low density region. We carried out a timing analysis for both Mrk 464 and UGC 32, and a spectral analysis for Mrk 464. The light curve of Mrk 464 shows the possibility of periodic X-ray flux variation and UGC 32 shows weak, but rapid variation.
Scaling in Modeling of Core Losses in Soft Magnetic Materials Exposed to Nonsinusoidal Flux Waveforms and DC Bias

Assuming that core loss data of Soft Magnetic Materials obey scaling relations, models describing the power losses in materials exposed to non-sinusoidal flux waveforms and DC Bias conditions have been derived. In order to test these models, the measurement data for two materials have been collected and the core losses calculated. Agreement between the experimental data and the model predictions is satisfactory.
Music, time, and international political economy: making coevalness

Abstract Recent critical studies in International Political Economy (IPE) have engaged with the ‘temporal turn’ in International Relations. However, outside of postcolonial critiques, this temporal turn in IPE has not considered how subjects share time or how coevalness is produced. This paper explores the problem of coevalness by asking how music produces shared time and plural temporalities. It analyses a collection of experimental electronic music, 4 Women No Cry, arguing that mobilising vulnerabilities through the co-presence of bodies in ‘musicking’ points towards possibilities for subjectivity beyond the individuated, sovereign, autonomous individual subject and for an intercorporeal subjectivity emerging from the intertwining of material and social relations. This article thus does not offer an ‘IPE of music’ but rather asserts, via music, a deepening of the critique of temporality and of subjectivity, opening further possibilities for political critique in IPE.
A Critical Review on the Junction Temperature Measurement of Light Emitting Diodes

In the new age of illumination, light emitting diodes (LEDs) have been proven to be the most efficient alternative to conventional light sources. Yet, in comparison to other lighting systems, LEDs operate at low temperatures while junction temperature (Tj) is is among the main factors dictating their lifespan, reliability, and performance. This indicates that accurate measurement of LED temperature is of great importance to better understand the thermal effects over a system and improve performance. Over the years, various Tj measurement techniques have been developed, and existing methods have been improved in many ways with technological and scientific advancements. Correspondingly, in order to address the governing phenomena, benefits, drawbacks, possibilities, and applications, a wide range of measurement techniques and systems are covered. This paper comprises a large number of published studies on junction temperature measurement approaches for LEDs, and a summary of the experimental parameters employed in the literature are given as a reference. In addition, some of the corrections noted in non-ideal thermal calibration processes are discussed and presented. Finally, a comparison between methods will provide the readers a better insight into the topic and direction for future research.
Single CT Appointment for Double Lung and Colorectal Cancer Screening: Is the Time Ripe?

Annual screening of lung cancer (LC) with chest low-dose computed tomography (CT) and screening of colorectal cancer (CRC) with CT colonography every 5 years are recommended by the United States Prevention Service Task Force. We review epidemiological and pathological data on LC and CRC, and the features of screening chest low-dose CT and CT colonography comprising execution, reading, radiation exposure and harm, and the cost effectiveness of the two CT screening interventions. The possibility of combining chest low-dose CT and CT colonography examinations for double LC and CRC screening in a single CT appointment is then addressed. We demonstrate how this approach appears feasible and is already reasonable as an opportunistic screening intervention in 50–75-year-old subjects with smoking history and average CRC risk. In addition to the crucial role Computer Assisted Diagnosis systems play in decreasing the test reading times and the need to educate radiologists in screening chest LDCT and CT colonography, in view of a single CT appointment for double screening, the following uncertainties need to be solved: (1) the schedule of the screening CT; (2) the effectiveness of iterative reconstruction and deep learning algorithms affording an ultra-low-dose CT acquisition technique and (3) management of incidental findings. Resolving these issues will imply new cost-effectiveness analyses for LC screening with chest low dose CT and for CRC screening with CT colonography and, especially, for the double LC and CRC screening with a single-appointment CT.
Audio-Visual Stress Classification Using Cascaded RNN-LSTM Networks

The purpose of this research is to emphasize the importance of mental health and contribute to the overall well-being of humankind by detecting stress. Stress is a state of strain, whether it be mental or physical. It can result from anything that frustrates, incenses, or unnerves you in an event or thinking. Your body’s response to a demand or challenge is stress. Stress affects people on a daily basis. Stress can be regarded as a hidden pandemic. Long-term (chronic) stress results in ongoing activation of the stress response, which wears down the body over time. Symptoms manifest as behavioral, emotional, and physical effects. The most common method involves administering brief self-report questionnaires such as the Perceived Stress Scale. However, self-report questionnaires frequently lack item specificity and validity, and interview-based measures can be time- and money-consuming. In this research, a novel method used to detect human mental stress by processing audio-visual data is proposed. In this paper, the focus is on understanding the use of audio-visual stress identification. Using the cascaded RNN-LSTM strategy, we achieved 91% accuracy on the RAVDESS dataset, classifying eight emotions and eventually stressed and unstressed states.
Laparoscopic Single-Incision Triangulated Umbilical Surgery Adrenalectomy for Large (>5 cm) Tumors of the Adrenal Gland: Initial Experience with 16 Cases

Background and ObjectivesLaparoscopic single-incision triangulated umbilical surgery (SITUS), which enables the extraction of intraabdominal specimens through a single umbilical incision, has yet to be used to perform adrenalectomy. We have modified SITUS to enable extraction of large (>5 cm) adrenal masses with optimal cosmetic outcomes and investigated efficacy and safety. Methods. In this retrospective study, we analyzed data of 16 patients with adrenal tumors >5 cm who had undergone adrenalectomy by SITUS between October 2015 and April 2018. Two C-shaped incisions were made around the umbilicus and sutured centripetally. After extracting the specimen, we evaluated these patients' operative/postoperative data. Results. SITUS was performed in all 16 patients without conversion to laparoscopic or open surgery. The mean operation time was 75.31 ± 21.54 min (intraperitoneal time 41.94 ± 17.57 min; incision suturing time 33.38 ± 6.34 min). The estimated median blood loss was 57.5 mL (range 30–610 mL). Drainage time and duration of hospital stay were 55.69 ± 12.92 h and 3.94 ± 0.90 d, respectively. After surgery, all incisions were hidden under the umbilicus. Three patients developed keloid diathesis, resulting in enlargement of their scars. Conclusions. SITUS is a safe and feasible procedure for removing large adrenal tumors. In addition to its cosmetic advantages, SITUS facilitates functional recovery, particularly in patients with large adrenal tumors.
The Effectiveness of Physical Activity Interventions on Depression in Korea: A Systematic Review and Meta-Analysis

Since the onset of the COVID-19 pandemic, Korea has ranked first in the OECD, with a prevalence of 36.8% of depression. Thus, this study aimed to estimate the effect size of physical activity as an alternative tool for depression symptoms using meta-analysis. A meta-analysis on depressive symptoms was performed on 18 studies published in Korean domestic journals. The moderating variables hypothesized in this study included age groups of participants; depressive symptoms; and frequency, intensity, time, type, and duration of the intervention. The overall effect size of physical activity on depression was moderate (0.56 [95% CI: 0.39 to 0.91]). Specifically, physical activity was slightly more effective in reducing depression in participants with an 18–64 age group compared to older people over 65 years old, while it was most effective for participants without depressive symptoms compared to participants with mild and severe symptoms. Further, the subgroup analysis revealed that performing two times a week for 30 to 60 min with progressive intensity for 1–8 weeks may be the most effective for Koreans. The results of this study can provide guidelines for the most effective physical activity program for Koreans.
The Application of Computer Augmented Reality Technology in Ancient Murals

In recent years, the country has given the green light to the development of augmented reality technology. Various preferential policies have sprung up such as mushrooms after rain, and augmented reality technology has gradually been applied to all aspects of our lives. In terms of cultural relic protection, the research and protection of ancient murals are undoubtedly not the most difficult. In terms of protection, murals are very fragile, and there are many factors that need to be paid attention to, such as air humidity, temperature, microorganisms, and the shedding of mud layers. In terms of research, the study of frescoes requires a lot of careful observation, but exhaled breath or body temperature that researchers get too close to can have unforeseen consequences. Based on this, the article expounds the composition of the augmented reality technology system. Through image recognition, three-dimensional tracking registration, virtual-real combination, and other technologies, the image obtained by the camera is recognized, and then the environment where the mural is located is a virtual scene through three-dimensional tracking technology. We build and finally use the combination of virtual and real technology to make the ancient murals vividly presented in front of us for our researchers to study more conveniently. The use of Gaussian function, SURF algorithm, FREAK algorithm, RANSAC algorithm, and so on to improve the augmented reality technology system makes the presentation of ancient murals more detailed and realistic. After experiments, we came to the conclusion that the ancient murals processed by augmented reality technology are far more detailed and more complete than the pictures taken by ordinary cameras. Processing ancient frescoes is also far less time-consuming than the existing image processors.
Determination of the parameters of freeze-drying honey

The article presents the results of studies of freeze-drying of various types of honey. The purpose of the research was to determine the optimal parameters for the freeze-drying of honey. The physical and chemical parameters of three types of honey produced in the East Kazakhstan region were previously studied. The results showed that the studied prototypes meet the regulatory requirements for the quality of natural honey. It has been established that in terms of moisture content, sunflower honey differs from mountain honey and sweet clover (15 %, 17.3 % and 17.2 %, respectively), and also contains a high amount of reducing sugars (87.9 %), however, the mass fraction of sucrose is 2.5 %. It is noted that the highest content of sucrose in mountain honey is 4.5 %. The diastase number is an indicator of the quality and naturalness of honey and, according to the requirements of GOST, should be at least 8 Gote units, the results show that the studied samples of honey contain from 13.1 to 15.1 units, which confirms the influence of the geographical origin of honey. According to the value of water activity, all types of honey are products with low humidity and long-term storage. The optimal technological modes of freeze-drying of honey have been established, which range from minus 30 °C to minus 40 °C degrees.
The intensities of Balmer lines in low resolution integrated light spectra of globular clusters

We introduce a study of the depths and widths of Balmer absorption lines in low resolution ( Δ 𝜆 / 𝜆 ∼ 1000) integrated light (IL) spectra of globular clusters (GCs) depending on the following parameters: age, metallicity (Z) and helium mass fraction (Y). The parameters of stellar atmospheres used to calculate synthetic IL spectra of GCs are set by theoretical isochrones of stellar evolution. As the age increases, the luminosities and effective temperatures of the Main sequence turnoff stars decrease. The analysis of low resolution spectra demonstrates that the depths and widths of the Balmer absorption lines H 𝛿 , H 𝛾 and H 𝛽 in IL spectra of GCs decrease accordingly. On the other hand, as the contribution of hot blue horizontal branch (HB) stars in IL spectra becomes more and more significant, the depths and widths of hydrogen lines increase. These changes are non-monotonic. In this paper we explore characteristics of these changes in spectra of GCs with Z=0.002. Our study contributes to the progress of the research on the properties of HB stars, the contribution of their radiation to IL spectra of GCs and the accuracy of determination of ages and Y for GCs in galaxies.
Circularly Polarized Elliptical Cavity-Backed Patch Antenna Array for Millimeter-Wave Applications

This work introduces cost-effective solution for a millimeter-wave (mmW) antenna array development. We suggest an elliptical cavity-backed patch antenna array to achieve a wideband and high-gain circularly polarized (CP) at mmW frequencies. The whole array only uses two PCBs and a metallic fixture to build. We introduce a new configurable subarray with <inline-formula> <tex-math notation="LaTeX">$2\times $ </tex-math></inline-formula> 1 radiating elements that are formed by two partially overlapped elliptical cavities to generate the radiation together with the driven patches of the subarray. The subarray can produce a wide impedance bandwidth of 37%, a wide 3 dB axial ratio (AR) bandwidth of 29.6%, and a maximum gain of 11.6 dBic. Based on the result from the subarray, we design a 32-element antenna array by a <inline-formula> <tex-math notation="LaTeX">$4 \times $ </tex-math></inline-formula> 4 antenna array configuration. The power distribution is realized by a 1-to-16 full-corporate feed network. The measured results show that the proposed CP array obtains an impedance bandwidth of 31.5% and a 3 dB AR bandwidth of 24%. In addition, the gain of the array is from 19.1 to 21 dBic within the 3 dB AR bandwidth. With wide impedance and AR bandwidths, the proposed antenna array can find potential applications in long-range mmW communications.
RENORMGROUP INVARIANTS AND APPROXIMATIONS OF MAPPINGS

The relationship between mappings of sets and renormalization group transformations is established, and renormalization group invariants of such mappings are found. These results are valid both for continuous and discrete mappings and for various dimensionality of image and preimage of the mappings too. It is suggested a number of mapping approximations improved in comparison with an ordinary power expansion. The approximations take into account the global one-to-one character of the mappings. The method is illustrated by a number of examples: by reconstructing of some analytical functions, calculating the integral of the typical partition function of statistical mechanics and the ground state energy for the quartic anharmonic oscillator. In the whole range of nonlinearity parameter varying from zero up to infinity the accuracy of the RG approximation based on a few terms of divergent series is about 0.06% in the next to last case and 0.004% in the last one.
Redox-Regulation in Cancer Stem Cells

Cancer stem cells (CSCs) represent a small subset of slowly dividing cells with tumor-initiating ability. They can self-renew and differentiate into all the distinct cell populations within a tumor. CSCs are naturally resistant to chemotherapy or radiotherapy. CSCs, thus, can repopulate a tumor after therapy and are responsible for recurrence of disease. Stemness manifests itself through, among other things, the expression of stem cell markers, the ability to induce sphere formation and tumor growth in vivo, and resistance to chemotherapeutics and irradiation. Stemness is maintained by keeping levels of reactive oxygen species (ROS) low, which is achieved by enhanced activity of antioxidant pathways. Here, cellular sources of ROS, antioxidant pathways employed by CSCs, and underlying mechanisms to overcome resistance are discussed.
Large non-gaussianity in a non-minimally coupled derivative inflationary model with Gauss-Bonnet correction

We study a nonminimal derivative inflationary model in the presence of the Gauss-Bonnet term. To have a complete treatment of the model, we consider a general form of the nonminimal derivative function and also the Gauss-Bonnet coupling term. By following the ADM formalism, expanding the action up to the third order in the perturbations and using the correlation functions, we study the perturbation and its non-Gaussian feature in details. We also study the consistency relation that gets modified in the presence of the Gauss-Bonnet term in the action. We compare the results of our consideration in confrontation with Planck2015 observational data and find some constraints on the model’s parameters. Our treatment shows that this model in some ranges of the parameters is consistent with the observational data. Also, in some ranges of model’s parameters, the model predicts blue-tilted power spectrum. Finally, we show that nonminimal derivative model in the presence of the GB term has capability to have large non-Gaussianity.
Observation of inverse spin hall effect in bismuth selenide

Bismuth Selenide (Bi2Se3) is a topological insulator exhibiting helical spin polarization and strong spin-orbit coupling. The spin-orbit coupling links the charge current to spin current via the spin Hall effect (SHE). We demonstrate a Bi2Se3 spin detector by injecting the pure spin current from a magnetic permalloy layer to a Bi2Se3 thin film and detect the inverse SHE in Bi2Se3. The spin Hall angle of Bi2Se3 is found to be 0.0093 and the spin diffusion length in Bi2Se3 to be 6.2 nm at room temperature. Our results suggest that topological insulators with strong spin-orbit coupling can be used in functional spintronic devices.
High-Frequency Injection Angle Self-Adjustment Based Online Position Error Suppression Method for Sensorless PMSM Drives

In the high-frequency (HF) signal injection based position sensorless permanent magnet synchronous motor (PMSM) drives, there is an estimated position error caused by the cross-saturation effect and other factors. In order to suppress the position error, an HF injection angle self-adjustment based online suppression method is proposed in this letter. By tracking the sign of the increment of the absolute back electromotive force in the estimated frame, the criterion of the HF injection angle self-adjustment can be determined online and the position error can be mitigated effectively. This method can avoid the offline measurement or the variation of the operating state, which has a satisfactory suppression effect for the position error under different operating conditions. The effectiveness is verified by experiments on a 2.2-kW PMSM drive platform.
