Transcending Socio-Ecological Crisis by Means of the State or Revolution?

ABSTRACT The exacerbated socio-ecological crisis, including the devastating COVID-19 pandemic during the last few years, has given rise to a variety of interpretations and strategies to face this crisis. Some researchers have suggested that the state is the single most effective agent capable of mobilizing the amount of resources and the policies required to overcome a crisis of such a broad scope and devastating impact. This paper analyzes the causes of the multifaceted and deepening socio-ecological crisis to show that the root cause behind this crisis is the capitalist mode of production itself. Subsequently, I interrogate those approaches proposing the state as a strategic mechanism to combat and overcome the crisis. It is outlined that the class-based (non-neutral) character of the state will tend to reproduce the prevailing capitalist relations of production, namely the basic conditions for the generation and exacerbation of this crisis. As is finally suggested, it is only with a revolutionary transformation of society that the working social majority will be able to radically undo the fundamental causes of the crisis and create the conditions for a peaceful and sustainable development on a planetary level.
SPH and Riemann Solvers

Smooth particle hydrodynamics (SPH) is usually based on equations derived from the momentum and thermal energy equations of fluid dynamics. Artificial viscosity is added to these equations to handle shocks. In this paper we show how the equations may be formulated using the specific energy equation instead of the thermal energy equation. The resulting equations are very similar to the equations constructed for Riemann solutions of compressible gas dynamics. In particular the artificial viscosity is analogous to terms constructed from signal velocities and jumps in variables across characteristics. When applied to shock tubes, blast waves, wall shocks, and the Roberts and Sjogreen problems the new equations give very good results. They also provide the basis for the generalization of SPH to relativistic flows.
The Determinant Factors for Employees to Leave (A Case Study in a Paint Chain Retailer)

High turnover is one of the problems faced by companies, especially small and medium enterprises. PT Fakta Asia Jaya, or Fakta Retail or Fakta Group, is one of the oldest semi-modern paint chain retailers and experiences a high turnover rate, more than the average industry. The company services depended on employee knowledge and support. The higher turnover rate becomes the real problem with the cost of hiring, training, sales, and services, which might affect profitability in the long run. Many factors, such as age (generational differences), gender, length of work, marital status, job satisfaction, compensation satisfaction, and organizational culture, influence employees’ decision to leave the company. This research uses qualitative methodology through an in-depth interview approach with questions about job satisfaction, compensation satisfaction, and organizational culture conducts information collected. This approach was chosen to understand whether those factors significantly influence their decision. This study proposes a recommendation for the business situation and to retain the current employee, especially the millennial generation. Based on the result of the study, it was suggested that the factors related to the employee leaving are mainly personal reasons and related to job satisfaction and compensation benefit. The other aspect emphasized by millennials is looking for career advancement and work-life balance between the family. Also, it is found that the higher risk of the job tends to look at a higher salary or to be financially incentivized; the importance of being valued and communicating in every variable makes all generations feel satisfied and fulfilled.
How Early Nutrition and Foundational Cognitive Skills Interconnect? Evidence from Two Developing Countries

We use unique data collected in Ethiopia and Peru as part of the Young Lives Study to investigate the relationship between early undernutrition and four foundational cognitive skills, the first two of which measure executive functioning: working memory, inhibitory control, long-term memory, and implicit learning. We exploit the rich longitudinal data available to control for potential confounders at the household level and for time-invariant community characteristics. We also exploit the availability of data for paired-siblings to obtain household fixed-effects estimates. Overall, we find robust evidence that stunting is negatively related with the development of executive functions, predicting reductions in working memory and inhibitory control by 12.6% and 5.8% of a standard deviation. Our results shed light on the mechanisms that explain the relationship between early nutrition and school achievement tests suggesting that good nutrition is an important determinant of children’s learning capacities.
Linear maps and impulse responses

Several results are given concerning the representation of causal (mainly) linear operators defined on a set of locally integrable inputs. These results establish the existence of impulse responses and associated integral representations, as well as the convergence of a classical sum to an integral, in a general setting in which a certain continuity condition plays a central role. They also provide necessary and sufficient conditions for a causal linear operator to have a convolution representation with a continuous impulse-response function. >
Kinetic theory for plane flows of a dense gas of identical, rough, inelastic, circular disks

Grad’s method of moments is employed to derive balance laws and constitutive relations for plane flows of a dense gas consisting of identical, rough, inelastic, circular disks. Two temperatures are involved; these are proportional to the kinetic energies associated with fluctuations in translational velocity and spin, respectively. When the single particle velocity distribution function is assumed to be close to a two‐temperature Maxwellian, two distinct theories are obtained. One applies when the particles are almost smooth and the collisions between them are nearly elastic; the other applies to nearly elastic particles that, in a collision, almost reverse the relative velocity of their points of contact. I both cases energy is nearly conserved in collisions.
An Ontology-Based Innovative Energy Modeling Framework for Scalable and Adaptable Building Digital Twins

Digitalization of buildings and the use of IoT sensing and metering devices are steadily increasing, oﬀering new opportunities for more autonomous, eﬃcient, and ﬂexible buildings. As part of this transformation and inspired by the added value demonstrated in other domains, the concept of a building digital twin that can monitor, simulate, manage, and optimize building operation has received increased interest. To aid such digital twin implementations, accurate and adaptable simulation models are required, which can eﬀectively integrate and utilize the available data. However, traditional building modeling and digital practices, such as Building Information Modeling and white-box modeling tools, are not easily compatible with these requirements. This work presents an innovative and ﬂexible energy modeling framework based on the SAREF ontology. With a basis in the SAREF4BLDG extension for buildings and the deﬁned classes, diﬀerent models are presented for a selection of typical systems and devices such as spaces, space heaters, dampers, coils, etc. Using the generic semantics and relations of the SAREF4SYST extension, a method for linking and simulating component models is then presented. A proof-of-concept of the modeling framework is provided, showing its application and feasibility to provide a dynamic simulation of the diﬀerent systems and devices included in a demonstration case. Finally, a future line of work is identiﬁed considering the implementation of the modeling framework in an actual building case study, including integration with actual sensing equipment to demonstrate diﬀerent digital twin services such as performance monitoring, strategy planning, and operational optimization.
A Very Large Array search for emission from HI associated with nearby Lyman alpha absorbers

We present a sensitive Very Large Array (VLA) search for H I emission from the vicinity of the Lyman alpha clouds in the Virgo Cluster, which were recently discovered with Hubble Space Telescope (HST) in absorption toward the nearest quasar 3C273. We searched an area of 40 by 40 arcmin centered on 3C273, covering a velocity range from 840 to 1840 km/s. The bandpass was self-calibrated on 3C273 leading to a spectral dynamic range of better than 10(exp 5) to 1. No H I was detected. The rms noise in the final images corresponds to a 3 sigma column density sensitivity of 2.8 x 10(exp 19) sq cm on scales of a few kpc. Small H I clouds could have been detected down to a few times 10(exp 6) solar mass. Our failure to detect H I emission at the higher column densities sets a lower limit to the radius of the Lyman alpha clouds of 3.9 kpc, assuming a spherical geometry.
Evolution of a Protobinary: Accretion Rates of the Primary and Secondary

We reexamine accretion onto a protobinary based on two-dimensional numerical simulations with high spatial resolution. We focus our attention on the ratio of the primary and secondary accretion rates. Fifty-eight models are made for studying the dependence of the accretion rates on the specific angular momentum of infalling gas jinf, the mass ratio of the binary q, and the sound speed cs. When jinf is small, the binary accretes the gas mainly through two channels (type I): one through the Lagrange point L2 and the other through L3. When jinf is large, the binary accretes the gas only through the L2 point (type II). The primary accretes more than the secondary in both the cases, although the L2 point is closer to the secondary. After flowing through the L2 point, the gas flows halfway around the secondary and through the L1 point to the primary. Only a small amount of gas flows back to the secondary, and the rest forms a circumstellar ring around the primary. The boundary between types I and II depends on q. When jinf is very large, the accretion begins after several rotations (type III). The beginning of the accretion is later when jinf is larger and cs is smaller. Our result that the primary accretion rate is higher for a large jinf is qualitatively different from results of earlier simulations. The difference is mainly due to limited spatial resolution and large numerical viscosity in the numerical simulations thus far.
Optimal use of an extra server in a two station tandem queueing network

A two station tandem queueing system with given numbers of customers initially at each station and no arrivals is considered. There is a fixed server at each station, but also an additional server that can be dynamically allocated to wherever its use will do most good. There are differing linear holding costs at each station, and the aim is to use the extra server to minimize the expected total holding cost incurred until the system empties. It is shown that if either the extra server can be switched between the two stations at any time, or if it is restricted in use to just one station, where it can be turned on or off, then the optimal use of the server is such that after a service completion at one station, the effort devoted there never increases, and the effort devoted to the other station never decreases. >
Correcting Distortion of Images from Non-Metric Camera

Photogrammetric calibration methods for digital CCD cameras are usually capable of acquiring explicit distortion parameters. However, it would cause the correcting results to be less accurate due to irregular array with explicit image correction method. In order to produce images with less distortion, an implicit model was proposed in this paper. Moreover, the model was applied to correct images from a non-metric camera. The real tests with images indicate the improvement is more obvious in eliminating distortion on images.
On the higher–order Stokes phenomenon

During the course of a Stokes phenomenon, an asymptotic expansion can change its form as a further series, prefactored by an exponentially small term and a Stokes multiplier, appears in the representation. The initially exponentially small contribution may nevertheless grow to dominate the behaviour for other values of the asymptotic or associated parameters. In this paper we introduce the concept of a‘higher–order Stokes phenomeno’, at which a Stokes multiplier itself can change value. We show that the higher–order Stokes phenomenon can be used to explain the apparent sudden birth of Stokes lines at regular points and how it is indispensable to the proper derivation of expansions that involve three or more possible asymptotic contributions. We provide an example of how the higher–order Stokes phenomenon can have important effects on the large–time behaviour of partial differential equations.
Spatiotemporal regulation of maternal mRNAs during vertebrate oocyte meiotic maturation

Vertebrate oocytes face a particular challenge concerning the regulation of gene expression during meiotic maturation. Global transcription becomes quiescent in fully grown oocytes, remains halted throughout maturation and fertilization, and only resumes upon embryonic genome activation. Hence, the oocyte meiotic maturation process is largely regulated by protein synthesis from pre‐existing maternal messenger RNAs (mRNAs) that are transcribed and stored during oocyte growth. Rapidly developing genome‐wide techniques have greatly expanded our insights into the global translation changes and possible regulatory mechanisms during oocyte maturation. The storage, translation, and processing of maternal mRNAs are thought to be regulated by factors interacting with elements in the mRNA molecules. Additionally, posttranscriptional modifications of mRNAs, such as methylation and uridylation, have recently been demonstrated to play crucial roles in maternal mRNA destabilization. However, a comprehensive understanding of the machineries that regulate maternal mRNA fate during oocyte maturation is still lacking. In particular, how the transcripts of important cell cycle components are stabilized, recruited at the appropriate time for translation, and eliminated to modulate oocyte meiotic progression remains unclear. A better understanding of these mechanisms will provide invaluable insights for the preconditions of developmental competence acquisition, with important implications for the treatment of infertility. This review discusses how the storage, localization, translation, and processing of oocyte mRNAs are regulated, and how these contribute to oocyte maturation progression.
Assessment of properties of gluten‐based edible film formulated with beeswax and DATEM for hamburger bread coating

Abstract Using edible films and coatings is one of the effective methods of improving the quality of bread. The aim of the present work was the development of gluten‐based films containing lipids to be applied as bread coating, intending to improve quality and delay staleness. In this study, two types of lipids including beeswax and DATEM (diacetyl tartaric ester monoglycerides) were incorporated into gluten film at different levels. The findings showed that inserting both lipids together into gluten for film preparation, weakened the developed films in terms of mechanical and moisture barrier properties. Adding DATEM to the gluten film formulae decreased the elongation at the break and the tensile strength of the film. Using gluten‐beeswax coatings for hamburger bread, compared to gluten‐DATEM coatings, indicated a significant decrease in the hardness and staling feature. Moreover, applying sorbate as a preservative along with the solvents used in the film preparation prevented the growth of mold during the bread shelf life. In conclusion, the findings in this study indicated that the type and levels of lipids added to the edible gluten‐based films and coatings affected the film properties and coated hamburger bread quality, significantly.
χ2 TEST FOR THE COMPARISON OF WEIGHTED AND UNWEIGHTED HISTOGRAMS

Widely used χ2 homogenety test for comparison histograms(unweighted) is generalized for cases involving unweighted and weighted histograms. Numerical examples illustrate an application of the method for case of histograms with small statistics of events and for the case of histograms with large statistics of events. The method can be used for comparison of simulated data histograms against experimental data histograms
Are the Radiative Properties of Long Gamma-Ray Bursts Universal?

It is noted that the Liang-Zhang correlation can be accounted for with the particular viewing angle interpretation proposed by us earlier. The Ghirlanda correlation, recently generalized by Nava et al. to a wind profile, can be accounted for by the viewing angle interpretation accordingly generalized to a wind profile. Most of the scatter in the spectra and time-integrated brightness in gamma-ray bursts can thus be accounted for by variation in two parameters, (1) the viewing angle and (2) the jet opening angle, with very little variation in any other intrinsic parameters. The scatter in apparent isotropic equivalent radiated energy and other parameters is reduced by a factor of order 30 when each of these parameters is considered. Possible difficulties with alternative explanations are briefly discussed. It is also noted that the relative scatter in the Amati and Ghirlanda correlations suggests certain conclusions about the inner engine.
Diversity patterns of plant functional types in the Holocene of Central India: A case study on the Lonar Crater Lake pollen record

Diversity of Plant Functional Types (PFTs) along a sediment core drilled in Lonar Crater Lake, Central India, is analysed, based on previously published pollen data for a total of 115 depth levels and covering the past 9.2 kyr. Our results support concepts of a dominantly humid period persisting until ca. 5 ka, succeeded by a significantly drier phase with weaker monsoon, including various prominent drying pulses. Throughout the Holocene, plant diversity at Lonar was composed of a variable proportion of herbaceous PFTs (ca. 40–60%) and mainly angiosperm woody PFTs. Changes in herbaceous diversity account for a considerable part of the observed PFT data variability. PCA analysis reveals a total of four partly alternating diversity associations (DAs) interpretable in terms of vegetation spanning from drier Savanna and dry deciduous forest to (semi-) evergreen woody vegetation, mainly recorded in older strata. It is shown that the succession of the DAs is largely triggered by climate change inferred from other proxies. Correlation analysis with geochemical data testifies that the diversity signal obtained is largely unaffected by sedimentary processes and detrital inflow, highlighting the potential of this archive to reflect ‘true’ diversity signals, rather than artefacts of sedimentary processes. While warm and humid conditions promoted diversity, drying and weak monsoon tended to cause diversity loss. In contrast, the relative diversity of dry herbs increased during drier periods. Short-term variability in our data is evident in varying diversity percentages of single PFTs and their ratios. Changing ratios of dry on mesic herbs, the relation of shrub and tree diversity, tropical on temperate PFTs, and total plant diversity are likely related to solar cycles. Evidence for recurrent cooling episodes through solar forcing comes from the observed coincidence of Grand Solar Minima and minima in the tropical/temperate PFT ratio.
Quasistatic optical response of pairs of touching spheres with arbitrary dielectric permeability

The problem of polarization of two touching spherical particles, of any complex dielectric constant, immersed in a uniform external electric field is solved exactly in the tangent‐sphere frame. A straightforward integral over the continuum of eigenstates yields the dipole moment for fields parallel and perpendicular to the line joining the centers. Predictions are compared to those from a recent approximate model based on the method of images. A modified Clausius–Mossotti formalism is used to assess the impact on absorption and refraction at optical frequencies (in the quasistatic limit). Actual composite materials containing small touching sphere pairs are considered.

Over the past decade, the advent of organoid technology has allowed production of laboratory-grown organ tissues as a model system for human biological studies. The use of human organoids has allowed researchers to learn a great deal about human biology and disease mechanisms [1]. Organoids are unique three-dimensional culture systems that are self-organized and similar to actual human organs. Human organoids represent human physiology rather than human-like animal models or two-dimensional culture systems [2]. Kidney organoids model the structure and function of nephrons, which are subdivided into functionally distinct portions, containing podocytes with proximal and distal tubules [3–5]. Kidney organoids have been shown to recapitulate genetic kidney diseases and acute kidney injury, such as cisplatin-induced toxicity [3,4]. Additionally, organoids generated from patient-derived induced pluripotent stem cells (iPSCs) have potential applications in pharmaceutical drug testing and molecular medicine [6]. Recently, protocols for cost-effective bulk production of organoids have been developed and are well-suited for large-scale assays, such as drug screening and regenerative medicine [2,7]. In spite of the availability of kidney organoids, certain technical limitations are associated with the use of organoids. Extended culture of kidney organoids may lead to Deep learning outperforms kidney organoid experts
Elucidation of Antidiabetic Mechanism of Centella asiatica and Zingiber officinale- An In-vitro and In-vivo approach

: Zingiber officinale rhizome and Centella asiatica leaves are extensively consumed as dietary supplements, and they are also reported for their antidiabetic activity. However, no proper scientific evidence exists to support its antidiabetic property at a mechanistic level. The present study was designed to assess the in-vitro and in-vivo antidiabetic activity of hydroalcoholic extracts of Zingiber officinale rhizome and Centella asiatica leaves. In-vitro assays like alpha amylase as well as alpha glucosidase inhibition assay and glucose uptake by yeast cell assay have been performed. In-vivo activity was also evaluated in streptozotocin-induced diabetic albino rats. Acarbose and metformin are taken as standard drugs for comparison. Both the extracts elicited significant antidiabetic activity both in-vitro and in-vivo . The suppression of alpha amylase and alpha glucosidase enzymes is connected with their anti-diabetic action. It also demonstrated its impact by increasing glucose absorption by peripheral tissue and may have insulin memetic action. Although Centella asiatica was slightly more active than Ginger. It is very likely that regular ingestion of these two herbs in conjunction with conventional hypoglycemic medicines will aid in the maintenance of blood glucose levels in diabetic patients.
