Science fiction: The biology of the alien in Alien
Authors: Kuris Armand M. , Luo Mona Y.
Published: December 2023

Parasites serve as a source of threatening outcomes for humans in many science fiction plots. Perhaps the most notable is the Xenomorph of the first Alien film (1979). Here, we use the film as the sole source of direct information to hypothesize its life cycle. We recognize a distinctive infective stage, the face-hugger. To further its development as an internal parasite in its human host, we conceive features of its physiology. It has an astonishing ability to manipulate the behaviour of its doomed host, before emerging as the famous chest-burster. It is clearly a parasitoid, requiring the death of its host. A further metamorphosis completes its development to the adult predator that roams the doomed spaceship Nostromo. The Xenomorph adult stage bears an uncanny resemblance to a parasitoid of salps, pelagic invertebrates. Conceptualizing its mythic biology offers insight into the physiology and biochemistry of real parasites.

A Secure Anonymous Identity‐Based Virtual‐Space Agreement Method for Crowds‐Based Anonymous Communicate Scheme
Authors: Lin Kai , Wang Kaiyu , Shang Jin , Sun Qindong
Published: December 2023

Anonymous data exchange is in great demand in many situations, especially in remote control systems, in which a stable, secure, and secret data channel must be established between the controlling and controlled parties to distribute control commands and return data. In the previous work, we built a two‐level Virtual-Space anonymous communication scheme based on the Crowds System for performing secret data exchange in remote control systems. However, as an essential part of security and anonymity, participating nodes’ identity declaration and session key agreement phases were not well designed. In this paper, we redesign the identity agreement and declaration process and design an identity‐based Virtual-Space agreement method using the extended Chebyshev Chaotic Maps. In this approach, we transform the identity declaration process into a multilevel Virtual-Space agreement problem, where a series of security‐progressive Virtual-Space addresses are negotiated between the controller and the controlled nodes. The protocol can handle the case where there are multiple controllers in the system, and the negotiated Virtual-Space depends on the identity of the controller and the controlled node, so different controllers do not affect each other. The designed protocol is verified on Freenet, and we conclude this paper with a detailed security analysis of the method to prove that the method satisfies forward security.

Context. The BRIght Target Explorer (BRITE) mission collects photometric time series in two passbands with the aim of investigating stellar structure and evolution. Since their launches in the years 2013 and 2014, the constellation of five BRITE nano-satellites has observed a total of more than 700 individual bright stars in 64 fields. Some targets have been observed multiple times. Thus, the total time base of the datasets acquired for those stars can be as long as nine years.

Aims. Our aim is to provide a complete description of ready-to-use BRITE data, to show the scientific potential of the BRITE-Constellation data by identifying the most interesting targets, and to demonstrate how scientists can use these data in their research, and encourage them to do so.

Methods. We applied a decorrelation process to the automatically reduced BRITE-Constellation data to correct for instrumental effects. We performed a statistical analysis of the light curves obtained for the 300 stars observed in the first 14 fields during the first ~2.5 yr of the mission. We also performed cross-identification with the International Variable Star Index.

Results. We present the data obtained by the BRITE-Constellation mission in the first 14 fields it observed, from November 2013 to April 2016. We also describe the properties of the data for these fields and the 300 stars observed in them. Using these data, we detect variability in 64% of the presented sample of stars. Sixty-four stars, or 21.3% of the sample, have not yet been identified as variable in the literature and their data have not been analysed in detail. They can therefore provide valuable scientific material for further research. All data are made publicly available through the BRITE Public Data Archive and the Canadian Astronomy Data Centre.
Perturbative analysis of the effect of a magnetic field on gravito-inertial modes
Authors: Lignières F. , Ballot J. , Deheuvels S. , Galoy M.
Published: December 2023

Context. Magnetic fields have been measured recently in the cores of red giant stars thanks to their effects on stellar oscillation frequencies. The search for magnetic signatures in pulsating stars, such as γ Doradus (γ Dor) or slowly pulsating B stars, requires us to adapt the formalism developed for slowly rotating red giants to rapidly rotating stars.

Aims. We perform a theoretical analysis of the effects of an arbitrary magnetic field on high radial order gravity and Rossby modes in a rapidly rotating star.

Methods. The magnetic effects were treated as a perturbation. For high radial order modes, the contribution of the radial component of the magnetic field is likely to dominate over the azimuthal and latitudinal components. The rotation is taken into account through the traditional approximation of rotation.

Results. General expressions of the frequency shift induced by an arbitrary radial magnetic field are derived. Approximate analytical forms are obtained in the high-order, high-spin-parameter limits for the modes most frequently observed in γ Dor stars. We propose simple methods to detect seismic magnetic signatures and measure possible magnetic fields in such stars.

Conclusions. These methods offer new possibilities to look for internal magnetic fields in future observations, such as those of the PLATO mission, or of revisiting existing Kepler or TESS data.

The current study aimed to evaluate nutrition of black soldier fly larvae (BSFL) using Van Soest and fatty acid profile reared at different media. A total of five different treatments were used in this study as follows: fruit waste, food waste, tofu by-product, 50% fruit waste + 50% food waste, and 50% fruit waste + 50% tofu by-product. The parameters observed were fatty acid profile (saturated and non-saturated fatty acid) and fiber composition (Neutral Detergent Fiber, Acid Detergent Fiber, Cellulose, hemicellulose, and lignin). Fatty acid profile analysis was done using gas chromatography and fiber composition using Van Soest method. The result presented the composition of fatty acid in BSFL dominated by saturated fatty acid, namely lauric acid (34.28 – 38.39%), palmitic acid (17.45 –19.25%), arachidic acid (8.8 – 10.41%), myristic acid (7.35 – 9.36%), heptadecanoic acid (2.03– 2.91%), and decanoic acid (1.23 – 1.42%). Non-saturated fatty acid; linolelaidic acid (13.51 – 16.86%), oleic acid (1.64 – 1.91%), nervonic acid (1.341.46%), dan linolenic acid (0.65 – 1.03%) measured higher as compared to the rest. Fiber components measured were NDF (20.19 - 29.11%), ADF (10.43 – 17.55%), hemicellulose (8.86 – 11.56%), cellulose (2.51 –10.49%), and Lignin (0.14 – 0.75%). Respectively, in conclusion composition of growth media of BSFL influence the profile of fatty acid and fiber in BSFL. In addition, the media composed of 50% food wastes and 50% tofu by-product gave highest and most complete fatty acid profile as well as fiber composition.

Published: December 2023

Rice bran is one of waste products from rice processing that can be used as nonruminant feed ingredients, but high crude fiber contained limited its utilization. Reducing crude fiber content requires processing such as fermentation. Fermentation requires carbohydrates such as palmyra sap. The purpose of this research was to determine the changes in the content of dry matter, crude fiber and ash of rice bran added with palmyra sap at different fermentation periods. This research used a Complete Random Design with four treatments and five replications. The four treatments are DN0: without fermentation, DN3: 3 days fermentation, DN6: 6 days fermentation, and DN9: 9 days fermentation. The parameters measured were the content of dry matter, crude fiber, and ash. Data were analyzed using Analysis of Variance and continued with Duncan's Multiple Range Test. The results showed that fermentation periods decreased the crude fiber and ash content but had no significant effect on the dry matter content of rice bran. The 3 days fermentation period resulting the lowest crude fiber content.

hp-Robust multigrid solver on locally refined meshes for FEM discretizations of symmetric elliptic PDEs
Authors: Innerberger Michael , Miraçi Ani , Praetorius Dirk , Streitberger Julian
Published: December 2023

In this work, we formulate and analyze a geometric multigrid method for the iterative solution of the discrete systems arising from the finite element discretization of symmetric second-order linear elliptic diffusion problems. We show that the iterative solver contracts the algebraic error robustly with respect to the polynomial degree p ≥ 1 and the (local) mesh size h. We further prove that the built-in algebraic error estimator which comes with the solver is hp-robustly equivalent to the algebraic error. The application of the solver within the framework of adaptive finite element methods with quasi-optimal computational cost is outlined. Numerical experiments confirm the theoretical findings.

Published: December 2023

Longitudinal data on patient trends in body mass index (BMI) and the proportion that gains or loses significant weight before and after total knee arthroplasty (TKA) are scarce. This study aimed to observe patients longitudinally for a 2-year period and determine (1) clinically significant BMI changes during the 1 year before and 1 year after TKA and (2) identify factors associated with clinically significant weight changes.

A prospective cohort of 5,388 patients who underwent primary TKA at a tertiary health care institution between January 2016 and December 2019 was analyzed. The outcome of interests was clinically significant weight changes, defined as a ≥5% change in BMI, during the 1-year preoperative and postoperative periods, respectively. Patient-specific variables and demographics were assessed as potential predictors of weight change using multinomial logistic regression.

Overall, 47% had a stable weight throughout the study period (preoperative: 17% gained, 15% lost weight; postoperative: 19% gained, 16% lost weight). Patients who were older (odds ratio [OR] = 0.95), men (OR = 0.47), overweight (OR = 0.36), and Obese Class III (OR = 0.06) were less likely to gain weight preoperatively. Preoperative weight loss was associated with postoperative weight gain 1 year after TKA (OR = 3.03). Preoperative weight gain was associated with postoperative weight loss 1 year after TKA (OR = 3.16).

Most patients maintained a stable weight before and after TKA. Weight changes during the 1 year before TKA were strongly associated with reciprocal rebounds in BMI postoperatively, emphasizing the importance of ongoing weight management during TKA and the recognition of patients at higher risk for weight gain.

Level of evidence II (prospective cohort study).

Published: December 2023

As obesity becomes more prevalent, more patients are at risk of lower extremity osteoarthritis and subsequent total knee arthroplasty (TKA). This study aimed to test (1) the association of preoperative weight change with health care utilization and (2) the association of pre- and postoperative weight changes with failure to achieve satisfaction and minimal clinically important difference (MCID) in Knee injury and Osteoarthritis Outcome Score for pain (KOOS-Pain) and function (KOOS-PS) 1 year after TKA. Prospectively collected monocentric data on patients who underwent primary TKA were retrospectively reviewed. Multivariable logistic regression assessed the influence of BMI and weight change on outcomes while controlling for confounding variables. Outcomes included prolonged length of stay (LOS >3 days), nonhome discharge, 90-day readmission rate, satisfaction, and achievement of MCID for KOOS-Pain and KOOS-PS. Preoperative weight change had no impact on prolonged LOS (gain, p = 0.173; loss, p = 0.599). Preoperative weight loss was associated with increased risk of nonhome discharge (odds ratio [OR]: 1.47, p = 0.003). There was also increased risk of 90-day readmission with preoperative weight gain (OR: 1.27, p = 0.047) and decreased risk with weight loss (OR: 0.73, p = 0.033). There was increased risk of nonhome discharge with obesity class II (OR: 1.6, p = 0.016) and III (OR: 2.21, p < 0.001). Weight change was not associated with failure to achieve satisfaction, MCID in KOOS-Pain, or MCID in KOOS-PS. Obesity class III patients had decreased risk of failure to reach MCID in KOOS-Pain (OR: 0.43, p = 0.005) and KOOS-PS (OR: 0.7, p = 0.007). Overall, pre- and postoperative weight change has little impact on the achievement of satisfaction and clinically relevant differences in pain and function at 1 year. However, preoperative weight gain was associated with a higher risk of 90-day readmissions after TKA. Furthermore, patients categorized in Class III obesity were at increased risk of nonhome discharge but experienced a greater likelihood of achieving MCID in KOOS-Pain and KOOS-PS. Our results raise awareness of the dangers of using weight changes and BMI alone as a measure of TKA eligibility.

Background Currently, the methods for drainage of pelvic abscess primarily use computed tomography- or ultrasound-guided percutaneous drainage or surgical drainage. Endoscopic ultrasound-guided pelvic abscess drainage (EUS-PAD) is an alternative, minimally invasive tool to drain an abscess, localized close to the rectum or left colon, and therefore not accessible by other means.

Methods We report on the success of endoscopic ultrasound-guided drainage of peridiverticulitic abscess based on the two cases presented here. Using endoscopic ultrasound guidance an aspiration of the abscess from the endoluminal could be realized. After successive balloon dilatation via a guidewire while using X-ray imaging, the placement of pigtail or flap stent was performed. In addition, conservative therapy measures such as antibiotics, diet, and pain management were performed.

Results The interventions were successful in both patients, resulting in rapid recourse of discomfort, abscess size, and sepsis. After controlling the consequences of complicated diverticulitis, both patients underwent laparoscopic sigmoid resection with primary anastomosis and without ileostomy during an inflammation-free interval.

Conclusion Both cases demonstrate the advantages of EUS-PAD. A laparoscopic operation with primary anastomosis, lower perioperative risk, and without need of a protective ileostomy in early elective setting became possible by bridging the time until surgery by using EUS-PAD.
The roots and evolution of Iranian nationalism and its historiography
Authors: Asadian Reza
Published: December 2023

Nationalism, a multifaceted force, intricately shapes identities and histories across the globe. Iran, with its rich historical tapestry, exemplifies the complex interplay of nationalism, where diverse elements unite to forge a unique national identity. However, while various approaches to studying Iranian nationalism shed light on facets of this identity, each singularly fails to encapsulate its entirety. Through a systematic review, this article aims to amalgamate the factors influencing Iranian national identity, critically evaluating the strengths and limitations of each perspective and highlighting gaps in current research. The paper presents a categorization of existing scholarship into five distinct viewpoints. Beginning with the primordial underpinnings, it underscores their significance while noting their limitations in accounting for the influence of Orientalist narratives. The article subsequently delves into the effects of Western Orientalism on Iranian nationalism, highlighting the oft-neglected impact of global trends like industrialization. It further elucidates the instrumental role of leadership in crafting traditions and national identity. Finally, the study introduces a fresh perspective by emphasizing the centrality of the quest for self-determination in shaping Iranian identity. This analysis not only unveils the layered nuances of Iranian national identity but also proposes a robust framework, accentuating the imperative for sustained research in this continually evolving domain.

The similarities of quantum turbulence with classical hydrodynamics allow quantum fluids to provide essential models of their classical analog, paving the way for fundamental advances in physics and technology. Recently, experiments on 2D quantum turbulence observed the clustering of same-sign vortices in strong analogy with the inverse energy cascade of classical fluids. However, self-similarity of the turbulent flow, a fundamental concept in the study of classical turbulence, has so far remained largely unexplored in quantum systems. Here, thanks to the unique features of exciton–polaritons, we measure the scale invariance of velocity circulations and show that the cascade process follows the universal scaling of critical phenomena in 2D. We demonstrate this behavior from the statistical analysis of the experimentally measured incompressible velocity field and the microscopic imaging of the quantum fluid. These results can find wide application in both quantum and classical 2D turbulence.
Peer-to-peer energy trading in a community based on deep reinforcement learning
Authors: Wang Yiqun , Yang Qingyu , Li Donghe
Published: December 2023

With the massive access to distributed energy resources, an increasing number of users have transformed into prosumers with the functions of producing, storing, and consuming electric energy. Peer-to-peer (P2P) energy trading, as a new way to allow direct energy transactions between prosumers, is becoming increasingly widespread. How to determine the trading strategy of prosumers participating in P2P energy trading while the strategy can satisfy multiple optimization objectives simultaneously is a crucial problem to be solved. To this end, this paper introduces the demand response mechanism and applies the dissatisfaction function to represent the electricity consumption of prosumers. The mid-market rate price is adopted to attract more prosumers to participate in P2P energy trading. The P2P energy trading process among multiple prosumers in the community is constructed as a Markov decision process. We design the method of deep reinforcement learning (DRL) to solve the optimal trading policy of prosumers. DRL, by engaging in continual interactions with the environment, autonomously learns the optimal strategies. Additionally, the deep deterministic policy gradient algorithm is well-suited for handling the continuous and intricate decision problems that arise in the P2P energy trading market. Through the judicious construction of a reinforcement learning environment, this paper achieves multi-objective collaborative optimization. Simulation results show that our proposed algorithm and model reduce costs by 16.5%, compared to the transaction between prosumers and grid, and can effectively decrease the dependence of prosumers on the main grid.

Published: December 2023

We demonstrate geostationary satellite monitoring of large transient methane point sources with the US Geostationary Operational Environmental Satellites (GOES). GOES provides continuous 5- to 10-min coverage of the Americas at 1 to 2 km nadir pixel resolution in two shortwave infrared spectral bands from which large methane plumes can be retrieved. We track the full evolution of an extreme methane release from the El Encino—La Laguna natural gas pipeline in Durango, Mexico on 12 May 2019. The release lasted 3 h at a variable rate of 260 to 550 metric tons of methane per hour and totaled 1,130 to 1,380 metric tons. We report several other detections of transient point sources from oil/gas infrastructure, from which we infer a detection limit of 10 to 100 t h−1. Our results show that extreme releases of methane can last less than an hour, as from deliberate venting, and would thus be difficult to identify and quantify with low-Earth orbit satellites.

A classical firewall transformation as a canonical transformation
Authors: Strauss Nathaniel A , Whiting Bernard F
Published: December 2023

The firewall transformation put forward by ’t Hooft in recent years has made ambitious claims of solving the firewall problem and the black hole information paradox while maintaining unitary evolution. However, the theory has received limited attention from the community, especially in regards to its foundations in purely classical gravitational physics. This paper investigates the underlying assumptions of ’t Hooft’s firewall transformation before quantization. We find that the limiting procedure used by ’t Hooft in order to obtain an identification of the quantum operators for ingoing and outgoing particles near a black hole is not consistent. We propose a correction, which involves a more relaxed approximation regime. In the new approximation regime, we find a new classical analog for the firewall transformation for spherical shells, which allows evolving the spherical shells’ dynamics past their point of collision. In the classical theory, no firewall is removed, as both ingoing and outgoing matter is present on every spacelike hypersurface, and it does not appear that any firewalls will be removed after a canonical quantization.
Thin tubes of a massless scalar field as a possible source of dark energy
Authors: Lelyakov Alexander , Lelyakov Stepan
Published: December 2023

In the proposed work, we have investigated the possibility of using an ideal gas of thin tubes of a massless scalar field as a source of Dark Energy. If we assume the homogeneity and isotropy of such an ideal gas, then its equation of state can be estimated by examining the gravitational field of a solitary tube of a scalar field. We have studied the gravitational field of a thin axially symmetric tube of a massless scalar field that moves without changing its shape and size. It was shown that the degree of rarefaction of the gas of thin tubes of a massless scalar field significantly affects its equation of state. So, for example, for a highly rarefied gas, its equation of state will tend to the equality

p
=

ρ

, and for a super-compressed gas, to the equality

p
=

. In this case, when expanding, such a gas must sequentially go through all states from

Numerical optimization of dielectric properties to achieve process uniformity in capacitively coupled plasma reactors
Authors: Kim Ho Jun , Lee Kyungjun , Park Hwanyeol
Published: December 2023

This paper presents the results of our numerical analysis to optimize the dielectric properties to achieve process uniformity in the thin film deposition process using capacitively coupled plasma. The difference in the plasma density distribution was analyzed by changing the wafer material from silicon to quartz (or Teflon). Similarly, aluminum was compared with aluminum nitride as the electrode material, and the sidewall material was varied from quartz to a perfect dielectric to study the effect on the plasma characteristics. A two-dimensional self-consistent fluid model was used to analyze the spatial distribution of the plasma parameters. In terms of the process conditions, the gas pressure was set to 400 Pa, the input power was fixed to 100 W, and a radio frequency of 13.56 MHz was used. SiH4/Ar was used as the gas mixture, and these conditions were used as input for numerical simulations of the deposition state of the hydrogenated amorphous silicon layer. The radial spatial distribution of plasma parameters was confirmed to be modified by dielectric elements with low dielectric constants regardless of the type of element. Despite the thin wafer thickness, the use of a wafer with low permittivity weakens the electric field near the electrode edge due to the stronger surface charging effect. Additionally, by changing the material of the sidewall to a perfect dielectric, a more uniform distribution of plasma could be obtained. This is achieved as the peak values of the plasma parameters are located away from the wafer edge. Interestingly, the case in which half of the sidewall was specified as comprising a perfect dielectric and the other half quartz had a more uniform distribution than the case in which the sidewalls consisted entirely of a perfect dielectric.
