Feminist Voices in Boys Love Literature: Subverting Gender Norms and Empowering Women

Boys Love (BL) literature is a creative genre that has become popular online in the past 20 years. It mainly describes the emotional life of homosexuals, especially gay men. It is an important and controversial part of the Internet subculture active among young people. However, contrary to its content, the creators behind BL literature are often non-gay young women. Women create and appreciate BL novels through the Internet to express their demands for aesthetics, pure love, and equality. This kind of gender writing that breaks tradition has a bright spot of feminism, and though this may take a long time, it can help create a more friendly living space for women in a patriarchal society. This article analyzes female writers' subversion of male images in BL novels, thereby proving that BL culture satisfies women's demands for a more profound social status and equal rights and contributes to breaking the patriarchal society.

Artifactual atomic displacements on surfaces using annular dark-field images with image simulation.

We investigated artifactual atomic displacements on a Pt (111) surface using annular dark-field (ADF) scanning transmission electron microscopy images under ideal conditions with multi-slice image simulation. Pt atomic columns on the surface exhibited artifact displacement. The bright spots shifted slightly toward the interior of the crystal, indicating that ADF imaging underestimates atomic distance measurements on the crystal surface. Multiple peak fitting is an effective method for determining the positions of bright spots and obtaining more accurate atomic positions while reducing the impact of surface-related artifacts. This is important for the measurement of interatomic distances on crystal surfaces, particularly for catalyst particles.

Superposed Laguerre‐Gaussian Beams‐Based Orbital Angular Momentum Holography

AbstractOrbital angular momentum (OAM) holography implements OAM of light as an information carrier to reconstruct holographic images, due to a physically unbounded set of orthogonal OAM modes. Here, superposed Laguerre‐Gaussian (LG) beams are employed as incident beams to achieve OAM holography. Notably, this scheme utilizes exact complex‐amplitude modulation, as opposed to mere phase‐only modulation, ensuring the maintenance of amplitude information. In the absence of a matching field, the output images retain the properties of incident beams with a varying number of bright petals in each sampling pixel. On the other hand, when specific incident beams are illuminated, the output images can be reconstructed with multiple matching fields that lead to different intensities. It is essential to recognize that the bright spot in each sampling pixel of the output image achieves its peak intensity only when the matching field is the conjugate of the incident light field. This work offers a novel perspective on reconstructing holographic images through various matching fields and modulating the brightness of distinct holographic images in OAM‐multiplexing holography. Additionally, a theoretically infinite number of bright petals in each sampling pixel can also serve as information carriers in holography.

Trifurcated Splitting of Water Droplets on Engineered Lithium Niobate Surfaces.

Controlled splitting of liquid droplets is a key function in many microfluidic applications. In recent years, various methodologies have been used to accomplish this task. Here, we present an optofluidic technique based on an engineered surface formed by coating a z-cut iron-doped lithium niobate crystal with a lubricant-infused layer, which provides a very slippery surface. Illuminating the crystal with a light spot induces surface charges of opposite signs on the two crystal faces because of the photovoltaic effect. If the light spot is sufficiently intense, millimetric water droplets placed near the illuminated spot split into two charged fragments, one fragment being trapped by the bright spot and the other moving away from it. The latter fragment does not move randomly but rather follows one of three well-defined trajectories separated by 120°, which reflect the anisotropic crystalline structure of Fe:LiNbO3. Numerical simulations explain the behavior of water droplets in the framework of the forces induced by the interplay of pyroelectric, piezoelectric, and photovoltaic effects, which originate simultaneously inside the illuminated crystal. Such a synergetic effect can provide a valuable feature in applications that require splitting and coalescence of droplets, such as chemical microreactors and biological encapsulation and screening.

The benchmark M dwarf eclipsing binary CM Draconis with TESS: spots, flares, and ultra-precise parameters

ABSTRACT A gold standard for the study of M dwarfs is the eclipsing binary CM Draconis. It is rare because it is bright (Jmag = 8.5) and contains twin fully convective stars on an almost perfectly edge-on orbit. Both masses and radii were previously measured to better than 1 per cent precision, amongst the best known. We use 15 sectors of data from the Transiting Exoplanet Survey Satellite (TESS) to show that CM Draconis is the gift that keeps on giving. Our paper has three main components. First, we present updated parameters, with radii and masses constrained to previously unheard-of precisions of ≈0.06 and ≈0.12 per cent, respectively. Secondly, we discover strong and variable spot modulation, suggestive of spot clustering and an activity cycle of the order of ≈4 yr. Thirdly, we discover 163 flares. We find a relationship between the spot modulation and flare rate, with flares more likely to occur when the stars appear brighter. This may be due to a positive correlation between flares and the occurrence of bright spots (plages). The flare rate is surprisingly not reduced during eclipse, but one flare may show evidence of being occulted. We suggest that the flares may be preferentially polar, which has positive implications for the habitability of planets orbiting M dwarfs.

Light Curve of HT Cassiopeiae

Photometric observations of the eclipsing dwarf nova HT Cas are presented in its quiescent state on 2022 October 20th for one complete orbital period. These data were taken with the RISE imager mounted on the Liverpool Telescope. The lcurve code was used to fit the light curve. System parameters were derived of mass ratio q = M 2/M 1 = 0.15 ± 0.01, angle of inclination i = 80.°98 ± 0.°18 and white dwarf radius of R 1 = 0.0128 ± 0.0003R ⊙. This gives solutions for the masses of the white dwarf and donor star of M 1 = 0.571 ± 0.017M ⊙ and M 2 = 0.088 ± 0.005M ⊙. The disk radius and bright spot radius with the best fit from the model were R disk = 0.51 ± 0.04a and R spot = 0.32 ± 0.02a. These are consistent with previous published observations.

Vertical acoustic blanking in seismic data from the German North Sea: a spotlight to shallow gas‐bearing incised channels

ABSTRACTSeismic data from the North Sea commonly show vertical acoustic blanking (VAB) often interpreted as fluid conduits with implications for Quaternary development. The robustness of this interpretation has long been controversial as the infill of tunnel valleys can also cause vertical blanking. Using 2D and 3D seismic data and sediment echosounder data from the German North Sea, we investigate VAB to determine a geological or imaging origin of these anomalies. We detected multiple VAB occurrences throughout the North Sea. 3D data from the Ducks Beak (‘Entenschnabel’) reveal a correlation of VAB with bright spots in incised channels directly below the seafloor. Large source–receiver distances allow imaging the subsurface below the channel without signal penetrating through it (undershooting). This method removes the blanking. Energy absorption by shallow biogenic gas trapped within the channels explains the observed VAB. Hence, the blanking represents an imaging artifact, highlighting the need for careful seismic processing with sufficient offset before interpreting such anomalies as fluid pathways. The channels belong to a postglacial channel system related to the now submerged lowlands of Doggerland. This work demonstrates the usability of mapping VAB to detect shallow features for paleo‐landscape reconstruction and identification of shallow gas for hazard assessments, for example.

The Arago–Poisson Spot: New Applications for an Old Concept

Herein, we report some specific properties and applications of the so-called Arago–Poisson spot in optics. This spot results from the diffraction of a plane wave by an occulting disk that leads to a small bright spot in its shadow. We discuss some of the properties of such beams. In particular, we focus on the ultimate size that can be reached for these beams, which depends on the diameter of the disk, the wavelength, and the distance from the disk. We also highlight self-healing and faster-than-light properties. Applications are then proposed. The applications mainly deal with new traps with nanometer sizes dedicated to the trapping of nanoparticles. We also discuss beams that change frequency during propagation and their application for signal delivery in a precise and determined area.

The Impact of Primary Care Physician Capacity on Preventable Hospitalizations: Identifying Bright Spots in the Appalachian & Mississippi Delta Regions.

Several studies have documented that higher rates of primary care physicians are associated with lower rates of preventable hospitalizations. Counties with higher rates of preventable hospitalizations are found in the Appalachian and Mississippi (MS) Delta Regions. (1) To determine if the association of primary care capacity with preventable hospitalizations is different in the Appalachian and MS Delta regions compared to the rest of the U.S., and (2) to explore primary care capacity in counties with lower-than-expected preventable hospitalization rates. This study modeled preventable hospitalizations with primary care physicians (PCP) per 100,000 (PCP capacity) while controlling for several factors. A spatial regime variable was also included, which modeled Appalachian and MS Delta regions separately. Next, PCP capacity was removed from the model and a geospatial residual analysis was performed to identify geographic clusters of counties with lower-than-expected rates of preventable hospitalizations (bright spots). PCP capacity in bright spots was then compared to that in counties with higher-than-expected rates (cold spots). Higher PCP capacity was significantly associated with lower rates of preventable hospitalizations in the rest of U.S. model, though was not significant for the Appalachian or MS Delta models. The residual analysis showed that compared to counties with higher-than-expected rates (cold spots), counties with lower-than-expected rates (bright spots) had significantly higher PCP capacity, though not in the MS Delta region. Consistent with previous literature, it was found that the factors associated with preventable hospitalizations vary by region, though the results are mixed when looking at the Appalachian and MS Delta regions separately. Future research should explore characteristics of bright spots within the Appalachian and MS Delta regions.

Investigation of proton single-event transient in CMOS image sensor

With the increasingly widespread application of CMOS image sensors (CIS) in radiation environments, such as aerospace, their radiation effects have gained attention. This paper investigates single-event transient (SET) caused by the proton direct ionization on CIS, combining both experimental and simulation methods. The proton beam energy used in the experiment is 12 MeV, with a flux up to 3.5 × 108 p/(cm2 s). Due to the periodicity of the proton beam, the CIS output displays a phenomenon of alternating brightness and darkness. When the proton beam flux is low, numerous SET bright spots with different outputs are observed. To comprehensively analyze these experimental phenomena, a typical three-dimensional 4T pinned photodiode model is constructed in TCAD, and relevant SET simulation is carried out. The results indicate that incident position, incident time, and the number of incident protons significantly affect the output of SET-generated bright spots, which are key factors contributing to the different bright spots observed in the experiment.

A case of central diabetes insipidus after COVID-19 as a probable diagnosis of lymphocytic infundibulo-neurohypophysitis with positive anti-rabphilin-3A antibodies with review of literature.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2, and various complications have been reported. Furthermore, there have been increasing reports of endocrinopathy related to COVID-19 following the pandemic. We report a 49-year-old healthy woman who developed rapid onset of polydipsia and polyuria three weeks after COVID-19. Laboratory tests indicated low urine osmolarity and increased serum osmolarity, and antidiuretic hormone (ADH) was undetectable. Urine osmolality remained low with water deprivation. Similarly, plasma ADH responses to hypertonic-saline infusion were blunted and urine osmolality increased in response to desmopressin. There was no clear evidence of anterior pituitary dysfunction. T1-weighted magnetic resonance imaging (MRI) showed pituitary stalk thickening and absence of posterior pituitary bright signal spots, suggesting the presence of hypophysitis. Based on these results, we made a probable diagnosis of lymphocytic infundibulo-neurohypophysitis (LINH) which have caused central diabetes insipidus. Positive findings for serum anti-rabphilin-3A antibodies, reported as a potential diagnostic marker for LINH, were also noted. Following oral desmopressin administration, polydipsia and polyuria were quickly improved, though treatment with desmopressin was still required over four months. This is the first report of a patient with a probable diagnosis of LINH after COVID-19 who tested positive for anti-rabphilin-3A antibodies. Positive findings for those antibodies suggest that pituitary dysfunction associated with COVID-19 is hypophysitis involving an abnormal immune mechanism. The presence of anti-rabphilin-3A antibodies may be useful as a non-invasive diagnostic marker of LINH and potentially serve as a valuable diagnostic aid in cases of LINH associated with COVID-19.

The dilemma of bright spots detected on magnetic resonance imaging of the brain for the diagnosis of multiple sclerosis: A retrospective evaluation of nonspecific white matter lesions

Reservoir Structural and Stratigraphical Evaluation of Sapele Deep Field, Niger Delta, Southern Nigeria.

Throughout the course of a field's existence, the oil and gas industry has not been very good at determining and forecasting how the stratigraphical and structural makeup of reservoirs will affect fluid flow. With harder-to-find reserves and growing development costs, it is critical to have a comprehensive plan in place to identify and reduce risks and uncertainties related to the stratigraphical and structural framework of reservoirs. Improving predictive capability is therefore the main task of our day. The research area's outlined strata thickens from north to south. On the other hand, the research area's considerable fault density is revealed by the structural interpretation. There is a noticeable throw to these faults, which may provide a route for the migration and deposit of hydrocarbons. Anticlines, which are important components of the majority of the Niger Delta's massive oil fields and have the potential to have several pay horizons, are typical structural types. The two defined horizons in the research region contain Sweet Spots (Bright spots), according to the Root-Mean Square Amplitude map analysis. 3D seismic cube and well log data were used to assess the research area's reservoir structural and stratigraphical framework. The study region is located between 50 33' 42.22" E and 50 53' 54.43" N.

The Study on the Fundamental of Dark and Bright Solitons

Abstract: The words bright and dark are taken from the field of optics, where they are used to describe the bright spots and black shadows that appear in optical fibres. However, in the 1830s, soliton observations were made in water. Oceanographers were initially taken aback by the discovery in the 1960s and 1970s that bright solitons were present on the surface of deep ocean waters. However, numerous experiments have since been conducted to investigate and validate the phenomenon, some of which have identified bright solitons as the cause of rogue waves at sea. Both bright and dark solitons have now been observed in BoseEinstein condensates, plasmas, fibre optics, and other environments. [30]

Recent Advances in Computational Convective Heat Transfer Study in a Sub-Channel for Nuclear Power Reactor and Future Directions

A nuclear power reactor's primary use is to generate thermal energy, which in turn produces electricity. The primary heat source is a nuclear fission event occurring inside the fuel rod. The convection heat is transmitted through the coolant by the heat energy generated at the fuel rod wall boundary. Better heat transfer is produced in the flow area by turbulence and irregularity. As a result, turbulent flow heat transfer may present a significant challenge when predicting and assessing the thermal performance of nuclear power reactors. Computational techniques in convective heat transfer have become indispensable for solving challenging issues in the fields of science and engineering thanks to the development of current sophisticated numerical methods and high-performance computer hardware. The development of novel computational techniques and models for complicated transport and multi-physical phenomena is constantly in demand throughout applicable disciplines. This chapter's objective is to provide some recent developments in computational techniques for convective heat transfer, taking into account research interests in the community of mass and heat transfer, and to showcase relevant applications in nuclear power plant engineering domains including future directions. This study describes the most recent advancements in nuclear reactor convective heat transfer research utilizing the computational fluid dynamics (CFD) method, particularly at Ansys Fluent. This work examines the convective heat transfer and fluid dynamics fluid dynamics for turbulent flows across three rod bundle sub-channels that are typical of those employed in the PWR-based VVER type reactor. In this paper, CFD analysis is carried out using the software tool Ansys Fluent. Temperature distribution profile, velocity profile, pressure drop, and turbulence properties were investigated in this study. Boundary conditions i.e. temperature, velocity, pressure, heat flux, and heat generation rate were applied in the sub-channel domain. The main obstacles and bright spots for the CFD methods in nuclear reactor engineering are discussed, which helps to further its further uses. We intend to research a full-length fuel bundle model for VVER-1200 in the future to gather specific fluid characteristic data and use the findings to analyze safety and operate nuclear power facilities in Bangladesh. This paper presents a thorough analysis of the sub-channel thermal hydraulic codes used in nuclear reactor core analysis. This review discusses several facets of previous experimental, analytical, and computational work on rod bundles and identifies potential future directions based on those earlier studies.

PERJANJIAN POLA KEMITRAAN DALAM PELAKSANAAN PEREMAJAAN TANAMAN KELAPA SAWIT

One effort to increase the productivity of oil palm plants is to carry out a replanting program. In implementing the oil palm plant rejuvenation program, most of the planters come from low-educated communities who lack knowledge regarding what and how partnership patterns are. It is the government's authority to regulate cooperative relations between plantation companies and farmers. This collaboration is carried out considering that planters may not be capable enough to work on rejuvenating their oil palm plantations, whereas if oil palm trees that are over 20-25 years old are not rejuvenated, they will no longer be productive and will produce little fruit. This collaboration is carried out by plantation companies as the core and plasma farmers/planters. In implementing this replanting program, there are several models of partnership patterns, one of which is the Intiplasm partnership pattern which is the most popular in implementing this program. The method used in this research is Normative Juridical with the research approach used is qualitative by examining statutory documents and comparing them with conditions in the field. The research results showed that the implementation of Minister of Agriculture Decree Number 940/KPTS/OT.210/10/97 concerning Guidelines for Agricultural Business Partnerships in the Implementation of Oil Palm Plant Rejuvenation has been carried out well, as evidenced by the existence of several regions in Indonesia that have successfully and completed following replanting using the intiplasma partnership pattern. This type of partnership pattern in implementing replanting is very important, because it can help people who do not have funds to continue participating in the replanting program. Then the form of legal protection obtained by farmers if a dispute occurs is through mediation and efforts to resolve disputes outside of court. Then, if no bright spot is found, the problem can then be resolved in court with all the consequences. Keywords: Palm Oil; Rejuvenation; Partnership Pattern.

On the formation of postnoon auroral bright spots during weak substorm activity

Postnoon auroral bright spots occurring around 15:00 magnetic local time (MLT) are typically caused by monoenergetic electrons accelerated by quasi-static electric field. In this study, we conduct an analysis of two special auroral spots observed by the Special Sensor Ultraviolet Spectrographic Imager (SSUSI) onboard the Defense Meteorological Satellite Program (DMSP) spacecraft. The first bright spot, observed on 05 June 2010, appears as a south-north aligned arc, while the second case, observed on 19 August 2005, takes the form of a circular patch. They both occurred at the equatorward edge of and are connected to the discrete aurora in the auroral oval. Particle measurements indicate that these two postnoon spots are primarily produced by precipitating electrons experiencing an acceleration process by quasi-static electric field. The average energy and integrated energy flux for the two cases are approximately 1.4 keV (1.5 keV) and 2.3 × 1012 (1.1 × 1012) eV/(cm2 s sr). It is suggested that the precipitating particles associated with the two cases originate from the boundary plasma sheet located poleward of the central plasma sheet. During the occurrences, the interplanetary magnetic field (IMF) By was nearly zero, while the IMF Bz was slightly negative, with values above −3 nT. Additionally, the geomagnetic AL index decreased to −160 and −200 nT, respectively. This indicates a potential relationship between the postnoon auroral spots and week substorm activities. Surprisingly, significant ion flow velocity was found to be nearly orientated with the postnoon spots. This suggests that the convection transports plenty of plasma along the south-north direction, offering sufficient particles for the formation of the postnoon auroral bright spots.

Analysis of Sexual Health Education in the Film “Dua Garis Biru” and its Urgency on Moral Internalization for Adolescents

Teenagers now experience a flood of information that continues to overflow every day. In the hands of teenagers, sex information is now easy to get. Even for those who don't intend to look for it, sometimes sex information circulates on their search engine homepage. It is so easy to find sex information, exposing teenagers to negative perceptions about sex. This is because most of the circulating sex information leads to pornography. This research raises one of the themed films of sex education, entitled "Dua Garis Biru" which was made to ward off misinterpretation of sex. This is considered by some as a bright spot to make people aware of the importance of sex education to build morale for their children. This study aims to identify sex education in the film "Dua Garis Biru". In addition, the depicted adolescent personalities were analyzed using the basis of their psychosocial and psychosexual theories. After that, identify how the process of moral internalization in adolescents by basing it on their cognitive development model. All of these theories will explain how sex is related to culture, and then affect moral development. This research is qualitative research using observation and documentation techniques in data collection. It used content, semiotic, and framing analysis which used sexual health, and social approaches. The results obtained from this study show that there are values of sex education related to moral internalization in the film "Dua Garis Biru". The value of sex education is contained in several messages such as the meaning of virginity, the danger of abortion, the reality of pregnancy in adolescents, and the negative effects of early marriage.

EXPLORING JAVANESE ISLAM: “THE ACCULTURATION OF RELIGIOUS DOCTRINE WITH CULTURAL RITUALS"

The entry of Islam into Java provided a new culture in the Javanese tradition regarding the teachings adopted by the people, this was due to acculturation and in the process the two teachings could coexist, in Javanese society itself it is known as Kejawen. This study discusses the meeting between Islam and Javanese culture which aims to find out more about the differences between Islamic teachings and Kejawen culture. The method used in finding the bright spot of this problem uses a qualitative method through a literature review approach. Based on the research conducted, it was found that the acculturation of Islam with Javanese culture originated from the spread of Islam by Wali Songo using culture as an intermediary, giving rise to a new understanding of Islam and the formation of Kejawen groups. In essence, the spread of Islam in Java was packed with Javanese cultural traditions and rituals.
