Primordial neutrino asymmetry evolution with full mean-field effects and collisions
Authors: Froustey Julien , Pitrou Cyril 
Published: March 2022

Abstract
Neutrino oscillations and mean-field effects considerably enrich the phenomenology of neutrino evolution in the early Universe. Taking into account these effects, most notably the neutrino self-interaction mean-field contribution, we revisit the problem of the evolution of primordial neutrino asymmetries including for the first time the complete expression for collisions, which describe scattering and annihilations with electrons/positrons and reactions among (anti)neutrinos. We show that a generalisation of the adiabatic transfer of averaged oscillations (ATAO) scheme, a numerical method previously developed without neutrino degeneracy and based on the large separation of time scales in this problem, is sufficient to reach the same accuracy as the full quantum kinetic equation integration, but is notably faster. This approximation highlights the physics of synchronous oscillations at play in the evolution of neutrino chemical potentials, especially in the particular case with only two-neutrino mixing. In particular, it allows to understand what controls the beginning and the amplitude of oscillations, but also why there is a subsequent regime of collective oscillations with larger frequencies. We also find that it is very important to use the full collision term instead of relying on damping-like approximations, in order not to overestimate how collisions reduce these synchronous oscillations. Finally we study qualitatively how mixing parameters affect the final neutrino configuration, and in particular we show that the CP-violating Dirac phase cannot substantially affect the final N
eff nor the final electronic (anti)-neutrino spectrum, and thus should not affect cosmological observables.
Effects of the hydropower regulation on dynamic stability of a renewable-based power system
Authors: Li Huanhuan 
Published: March 2022

Abstract
Renewable energy, particularly solar photovoltaic power integrated with hydropower, has become a remedy for replacing conventional electricity to provide important opportunities for the safety utilization of electric power. However, the solar photovoltaic power is intermittent and stochastic due to the uncertain solar irradiance, which can lead to the unstable operation of the complementary power system. For this consideration, this paper focuses on the stability mechanism of the hydropower regulation responding to the volatility of solar photovoltaic power. To achieve the analysis, a hydro-PV hybrid power system is established. Then, the effect of the hydropower regulation on dynamic stability of a hydro-photovoltaic hybrid system is investigated considering two hydropower regulation factors such as the optimization of hydropower control parameters and the performance of dynamic hydro regulation indicators. Finally, the optimized proportional, integral and derivative adjustment parameters are obtained, and the dynamic rule of regulation indicators responding to the volatility of photovoltaic power is also revealed. The obtained results not only help make an optimal decision for the coordinated operation of renewable-based power systems, but also benefit for the reduction of the operational cost and power curtailment.

Published: March 2022

Abstract
In recent years, with the progress of computer technology, artificial intelligence has been rapidly developed and begun to be applied in industry, economy and other aspects. Besides, with the pursuit of green hydrogen, hydrogen-based hybrid renewable energy systems have become the focus of the development of the hydrogen industry. This paper compares different artificial intelligence applications in hydrogen-based hybrid renewable energy systems and carries out a case study in a typical area. Firstly, this paper summarizes important works in literature, which use artificial intelligence methods to predict the supply chain of the renewable energy system, including the prediction of renewable energy system resources, output power, load demand and terminal electricity price. Secondly, main articles about artificial intelligence optimization algorithms used in renewable energy systems are also summarized, including swarm and non-swarm biological heuristics, physical or chemical heuristics and hybrid optimization algorithms. Finally, a case study is carried out in Tikanlik, Xinjiang, China. Tikanlik’s weather and load data train the artificial neural network to predict system output power. It shows that 99.32% of the relative error of the test set is less than 3%, which proves that this model can achieve good prediction results.
Study on Co-firing characteristics of NH3 and coal in the main burning zone of the coal staged combustion
Authors: Yuan J Y , Wang P P , Ruan C J , Huang X Y 
Published: March 2022

Abstract
The mathematical models including NH3 and pulverized coal were established, and the co-combustion characteristics of NH3/pulverized coal and NOx formation process in the main combustion zone (air consumption coefficient 0.9) of coal staged combustion are studied. The gas temperature distributions and NOx generation characteristics under different ammonia/pulverized coal ratios are investigated. The results show that the ammonia combustion and the NOx production is greatly enhanced by coal combustion when the ammonia and pulverized coal are mixed. For pure ammonia combustion, due to difficult ignition and lower burning rate in the lower gas temperature environment, the NO concentration formed in the furnace and at the outlet are very low; When the proportion of NH3 is 20%, the NOx concentration at the furnace outlet is the highest; when the ammonia gas ratio is 40%, NO at the outlet is lower than that of pure pulverized coal. In addition to a large amount of NO, there are also a large amount of NO2 and N2O in the high temperature region when ammonia and pulverized coal are mixed.
Classification of KPI lumps

Published: March 2022

Abstract
A large family of nonsingular rational solutions of the Kadomtsev–Petviashvili (KP) I equation are investigated. These solutions are constructed via the Gramian method and are identified as points in a complex Grassmannian. Each solution is a traveling wave moving with a uniform background velocity but have multiple peaks which evolve at a slower time scale in the co-moving frame. For large times, these peaks separate and form well-defined wave patterns in the xy-plane. The pattern formation are described by the roots of well-known polynomials arising in the study of rational solutions of Painlevé II and IV equations. This family of solutions are shown to be described by the classical Schur functions associated with partitions of integers and irreducible representations of the symmetric group of N objects. It is then shown that there exists a one-to-one correspondence between the KPI rational solutions considered in this article and partitions of a positive integer N.

Abstract
The Londerang Peat Protected Forest is the largest protected peat forest in Jambi Province with 12, 500 hectares. In 2015 there was a peat forest fire that destroyed the existing vegetation. Based on the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite, thousands of hotspots were observed from May to October. The condition of peat damage reaches 90%. Peat plays an important role in absorbing 75%of carbon so it should not be burned, dried, and used as plantation land. The purpose of the study was to determine changes in land cover, to determine the extent of revegetation, and to determine the area of unvegetated forest in the Londerang Peat Protected Forest area. The remote sensing method used is Image Classification assisted by ArcGIS Version 10.8 software with Landsat 8 satellite imagery. The analysis is carried out by making 20 color classifications on satellite image data, then the majority or pulling the minority pixel classes into the majority of pixel colors. From each code grid in the attribute table, the data are combined according to the landcover classification.The results of the spatial analysis of land cover In 2013-2018 there was very high forest degradation. In 2013 it was 2940.1 ha, in 2018 it was 191.3ha from the initial area of 12500 ha so that the Gonderang HLG was categorized as critical. Revegeted land is 354 ha with 164, 000 planted vegetation and the type of planted vegetation is endemic vegetation (Jelutung, swamp island, Gelam). The revegetation of the Londerang Peat Protection Forest has only been carried out for only 2.8% of the total land area.
Argon force field revisited: a molecular dynamic study

Published: March 2022

Abstract
We report the improvement of five argon force fields by scaling Lennard-Jones 6–12 potential (LJP) energy (ϵ) and distance (σ) parameters to reproduce liquid-vapor phase diagram and surface tension simultaneously, with molecular dynamics. Original force fields reproduce only liquid-vapor phase diagram among other properties except surface tension. Results showed that all new force fields obtained by scaling LJP parameters reproduce well the experimental surface tension and the liquid-vapor phase diagram, also the LJP energy and distance parameters converge in a nearby region in the ϵ-σ phase space, which is different from the original values. This study gives the intervals where the numerical values of ϵ and σ reproduce both properties mentioned above. Furthermore, a study to calculate surface tension to avoid finite size effects is shown.

Abstract

Objectives
The purpose of this study is to investigate health managers’ exposure to workplace violence (WPV) at construction sites and to review the statistical characteristics of experts in the safety and health fields using a gender-based analysis.

Methods
A preliminary survey of health managers at construction sites was conducted from March to April 2020 via the Health Managers Council in Construction Industry online community (https://band.us/band/62438722). Available national statistical data of safety and health personnel were reviewed.

Results
A total of 85 health managers (13 men, 72 women) responded to a preliminary survey. Health managers reported little physical violence (5.9%), while inappropriate work orders (83.5%) and sexual harassment (52.9%) were high, and health managers’ experience of sexual harassment was significantly higher among women than men (P &lt; 0.01). The professional safety and health field in Korea have a large gender gap, with few women. In particular, the proportion of women in the safety field was lower than in the health field.

Conclusions
Young female health managers in the male-dominated construction industry are more vulnerable to WPV, including sexual harassment. To reduce the risk of WPV exposure and gender discrimination among female health managers, it is necessary to increase regular employment and provide more practical WPV prevention education for all construction employees.
Competitive ability depends on mating system and ploidy level acrossCapsellaspecies

Published: March 2022

AbstractBackground and AimsSelf-fertilization is often associated with ecological traits corresponding to the ruderal strategy, and selfers are expected to be less competitive than outcrossers, either because of a colonization/competition trade-off or because of the deleterious genetic effects of selfing. Range expansion could reduce further competitive ability while polyploidy could mitigate the effects of selfing. If pollinators are not limited, individual fitness is thus expected to be higher in outcrossers than in selfers and, within selfers, in polyploids than in diploids. Although often proposed in the botanical literature and also suggested by meta-analyses, these predictions have not been directly tested yet.MethodsIn order to compare fitness and the competitive ability of four Capsella species with a different mating system and ploidy level, we combined two complementary experiments. First, we carried out an experiment outdoors in north-west Greece, i.e. within the range of the obligate outcrossing species, C. grandiflora, where several life history traits were measured under two different disturbance treatments, weeded plots vs. unweeded plots. To better control competition and to remove potential effects of local adaptation of the outcrosser, we also performed a similar competition experiment but under growth chamber conditions.Key ResultsIn the outdoor experiment, disturbance of the environment did not affect the phenotype in any of the four species. For most traits, the obligate outcrossing species performed better than all selfing species. In contrast, polyploids did not survive or reproduce better than diploids. Under controlled conditions, as in the field experiment, the outcrosser had a higher fitness than selfing species and was less affected by competition. Finally, contrary to the outdoor experiment where the two behaved identically, polyploid selfers were less affected by competition than diploid selfes.ConclusionsIn the Capsella genus, selfing induces lower fitness than outcrossing and can also reduce competitive ability. The effect of polyploidy is, however, unclear. These results highlight the possible roles of ecological context in the evolution of selfing species.
Emancipatory Visions: Using Visual Methods to Coconstruct Knowledge with Older Adults
Authors: Reyes Laurent , Shellae Versey H , Yeh Jarmin 
Published: March 2022

Abstract
This article calls for gerontologists to engage with visual methods in qualitative research as an innovative tool for community-engaged research that has potential to advance social justice in gerontology. Reflections about using visual methods from the intersectional standpoint of the authors, 3 younger women of color, are presented. In Working the Hyphen, J. Yeh shows how interpersonal dynamics are fundamental to visual methods and that attention to identity can provide new insights into aging while also reconstituting existing power dynamics that researchers must carefully consider. In Employing Elicitation Techniques With Experts, L. Reyes discusses how a colonial lens limits understandings of civic participation and erases contributions of Black, Indigenous, and People of Color (BIPOC) older adults, proposing that elicitation techniques offer opportunities for BIPOC older adults to contribute their expertise to the research process and dissemination of findings beyond an academic audience. In Pedagogy and Practicality, H. S. Versey describes promises and complexities of scaling visual methods on multiple levels—teaching future generations of researchers the philosophy and practice of photovoice; negotiating university and community relationships through a service-learning project; and navigating identity between herself, her students, and research participants. In sharing our self-narratives, we integrate reflexivity into the research process and challenge power dynamics in knowledge construction.

AbstractThe transcriptional regulatory network (TRN) of Pseudomonas aeruginosa coordinates cellular processes in response to stimuli. We used 364 transcriptomes (281 publicly available + 83 in-house generated) to reconstruct the TRN of P. aeruginosa using independent component analysis. We identified 104 independently modulated sets of genes (iModulons) among which 81 reflect the effects of known transcriptional regulators. We identified iModulons that (i) play an important role in defining the genomic boundaries of biosynthetic gene clusters (BGCs), (ii) show increased expression of the BGCs and associated secretion systems in nutrient conditions that are important in cystic fibrosis, (iii) show the presence of a novel ribosomally synthesized and post-translationally modified peptide (RiPP) BGC which might have a role in P. aeruginosa virulence, (iv) exhibit interplay of amino acid metabolism regulation and central metabolism across different carbon sources and (v) clustered according to their activity changes to define iron and sulfur stimulons. Finally, we compared the identified iModulons of P. aeruginosa with those previously described in Escherichia coli to observe conserved regulons across two Gram-negative species. This comprehensive TRN framework encompasses the majority of the transcriptional regulatory machinery in P. aeruginosa, and thus should prove foundational for future research into its physiological functions.

Published: March 2022

Abstract
As the design of genetic circuitry for synthetic biology becomes more sophisticated, diverse regulatory bioparts are required. Despite their importance, well-characterized 3′-untranslated region (3′-UTR) bioparts are limited. Thus, transcript 3′-ends require further investigation to understand the underlying regulatory role and applications of the 3′-UTR. Here, we revisited the use of Term-Seq in the Escherichia coli strain K-12 MG1655 to enhance our understanding of 3′-UTR regulatory functions and to provide a diverse collection of tunable 3′-UTR bioparts with a wide termination strength range. Comprehensive analysis of 1,629 transcript 3′-end positions revealed multiple 3′-termini classes generated through transcription termination and RNA processing. The examination of individual Rho-independent terminators revealed a reduction in downstream gene expression over a wide range, which led to the design of novel synthetic metabolic valves that control metabolic fluxes in branched pathways. These synthetic metabolic valves determine the optimal balance of heterologous pathways for maximum target biochemical productivity. The regulatory strategy using 3′-UTR bioparts is advantageous over promoter- or 5′-UTR-based transcriptional control as it modulates gene expression at transcription levels without trans-acting element requirements (e.g. transcription factors). Our results provide a foundational platform for 3′-UTR engineering in synthetic biology applications.
Past Is Prologue—1955
Authors: Ellenzweig Allen 
Published: March 2022

Abstract
It is 1955 and George Platt Lynes has left his hospital bed to attend the ballet at New York’s City Center for Music and Drama. Recently returned from Paris and Rome, seeing old friends like artist Pavel Tchelitchew and screen siren Gloria Swanson, Lynes is depleted in energy and spirit. He has been photographing the New York City Ballet and its preceding companies since 1935, but now his colleague Lincoln Kirstein has denied him the honor of documenting George Balanchine’s popular Christmas confection, The Nutcracker. The company’s dancers are among Lynes’s models and occasional intimates. These nocturnal outings are his pleasure and distraction. He has made repeated visits to see the young Julie Andrews in her New York debut in the 1920s musical pastiche The Boy Friend. This night at City Center, he does not last to the final curtain, but retreats to New York Hospital.
Missing Miss Stein and Hating Yale
Authors: Ellenzweig Allen 
Published: March 2022

Abstract
Returned to Englewood, George launches As Stable pamphlets with Gertrude Stein’s “Descriptions of Literature.” Planning other titles, George next prints Ernest Hemingway’s irreverent “Today Is Friday.” Its cover drawing by the voluble gay Jean Cocteau displeases the writer, offended to be implicated in a project involving “fairies.” Meanwhile, George briefly holds a lowly job at Brentano’s bookstore, even while proposing projects to keep him tethered to Gertrude Stein. She and George correspond frequently, but his equanimity wilts under the challenges of literary publishing. He follows modernist cultural trends, however, through the Manhattan salon of the eccentric Muriel Draper, whose bohemian gatherings approximate the daring of Paris’s Left Bank. At Draper’s, George becomes reacquainted with his Berkshire schoolmate, Lincoln Kirstein. In the fall of 1926, George is enrolled at Yale, but barely lasts the first semester. The conventionality of the male undergraduates appalls him. Instead, he plans a bookstore modeled on Sylvia Beach’s Shakespeare & Company.
The Triangle Takes Shape
Authors: Ellenzweig Allen 
Published: March 2022

Abstract
In late 1926/early 1927, George befriends American literary expatriates Monroe Wheeler and Glenway Wescott, visiting New York on business. Calling at their hotel, George falls hard for Monroe and intrudes on the pair’s established intimacy begun at the University of Chicago’s Poetry Club in 1918. When they return to France, George maintains an amorous correspondence with “Monie.” The two expats, previously living at the Riviera’s Hôtel Welcome among artist friends of Jean Cocteau, soon retreat to a modest villa so Wescott can concentrate on his fiction. There, at La Cabane, they host transatlantic artists and writers. George takes a summer college course on bookselling. In fall 1927, he opens the Park Place Book Shop in suburban Englewood, but soon loses interest. Wheeler and Wescott visit again in early 1928, whetting George’s appetite to join them on their return. The bookstore is sold by early March. In May, George crosses the Atlantic.
A Death in the Family
Authors: Ellenzweig Allen 
Published: March 2022

Abstract
Receiving word of an emergency, George and Russell rush home to find the Reverend Lynes dead. Hosting the mourners leaves George numb. He settles into a Midtown apartment/atelier. He photographs opera singers for NBC but lives on credit in the deepening Depression. He empties the rectory for Adelaide who moves to North Egremont where she converts the rear barn/office into a guest inn. George makes inroads into fashion photography. With Barbara’s help, he travels to Paris, calming Monie’s fears of his inconstancy. He and “the boys” meet up briefly with Russell assisting an automobile tour of Spain for Vassar girls. The tour ends tragically in a car accident killing a passenger, but brings Russell together with Mildred Akin, an art history graduate. By fall, the Lynes portrait of Gertrude Stein is slated for Time magazine’s cover. In Stein’s Autobiography of Alice B. Toklas, George discovers Stein’s cute but dismissive references to him and Glenway.
