Radio jets and outflows of cold gas

Massive gas outflows are considered a key component in the process of galaxy formation and evolution. It is, therefore, not surprising that a lot of effort is going in quantifying their impact via detailed observations. This short contribution presents recent results obtained from HI and CO observations of different objects where the AGN - and in particular the radio jet - is likely playing an important role in producing the gas outflows. These preliminary results are reinforcing the conclusion that these outflows have a complex and multiphase structure where cold gas in different phases (atomic and molecular) is involved and likely represent a major component. These results will also provide important constraints for establishing how the interaction between AGN/radio jet and the surrounding ISM occurs and how efficiently the gas should cool to produce the observed properties of the outflowing gas. HI likely represents an intermediate phase in this process, while the molecular gas would be the final stage. Whether the estimated outflow masses match what expected from simulations of galaxy formation, it is still far from clear.
Relationship between availability of states and pole/zero cancellations in H∞-control

This note compares servo systems designed with three methods of H/sub /spl infin//-control, that is, output feedback control, state feedback control and partial state feedback control. The three kinds of control use different information of the plant to generate the control input. We show that if more states are used, then the number of the pole/zero cancellations can be reduced. >
Preparation of Crosslinked Alginate-Cellulose Derivative Microparticles for Protein Delivery

Microparticle protein delivery system using alginate and cellulose derivative (HPC, HEC and CMC) composite system was prepared using external gelation with vibration technology. Bovine serum albumin (BSA) as a model protein was encapsulated using these biodegradable materials. This preparation showed an increase in encapsulation efficiency in comparison to the samples where pure alginate was used as the encapsulating material. Compared with the other microparticles, the 50:50 alginate/HEC samples exhibited significant encapsulation efficiency. Consequently, its release rate in the acidic medium was comparatively substantial and higher cumulative release in the simulated intestinal fluid (SIF) medium at the end of the dissolution study was observed to be high at around 86.17%.
A Real Data-Driven Clustering Approach for Countries Based on Happiness Score

In machine learning and data science literature, clustering is the task of dividing the observations (data points) into several categories in such a way that data points falling into one group are being dissimilar than the data points falling to the other groups such that the variation within a group is minimized and the variation between the groups is maximized. It falls under the class of unsupervised learning techniques. It is primarily a tool to classify individuals on the basis of similarity and dissimilarity between them. Our present study utilizes the world happiness data of 156 countries collected by the Gallup World Poll. Our study proposes a useful clustering approach with a very high degree of accuracy to classify different countries of the world based on several economic and social indicators. The most appropriate clustering algorithm has been selected based on different statistical methods. We also proceed to rank the top ten countries in each of the three clusters according to their happiness score. The three leading countries in terms of happiness from cluster 1 (medium happiness), cluster 2 (high happiness), and cluster 3 (low happiness) are Oman, Denmark, and Guyana, respectively, followed by United Arab Emirates, Finland, and Pakistan. Finally, we use four popular machine learning classification algorithms to validate our cluster-based algorithm and obtained very consistent results with high accuracy.
Kinetic theory of polarization in the Sunyaev-Zeldovich effect

We apply the coherency tensor formalism to the calculation of the spectral distortions imprinted in the intensity and polarization of the cosmic microwave background radiation due to the kinematic and thermal Sunyaev-Zeldovich effects (SZE). We obtain the first relativistic corrections to the intensity produced by the kinematic and thermal SZE, and the first correction to the polarization magnitude due to electron thermal motion.
Backscattering of stationary radiation in time-dependent random media: average intensity and intensity fluctuations

We consider backscattering of stationary radiation in a random medium whose wavespeed fluctuations depend on time and on space. We modify a previous derivation of the equations that govern the range-evolution of the spectra of the ensemble-averaged forward-and back-propagating components of the field and their second-order statistics, and extend the approach to treat the fourth-order statistics. The latter are governed by integro-difference equations that account for the broadening of the signal spectra due to the time-dependence of the random fluctuations. In the quasi-monochromatic regime, where spectra owing to a monochromatic excitation remain confined to a narrow band over extensive ranges, the integro-difference equations transform into ordinary differential equations that govern the time-dependence of the quantities of interest. We use this simplification to track the power fluxes and their fluctuations (scintillation) in a one-dimensionally stratified slab, where the wave-speed fluctuations depend on the range-coordinate normal to the planes of stratification, and also to treat modal propagation in a duct, where the wave-speed fluctuations depend on all three spatial dimensions. The results suggest that a Gaussian equilibrium is approached at large ranges, on a suitably defined backscattering scale that depends on the medium parameters and the geometry.
Classification supervise et non supervise des donnes de grande dimension

System method and apparatus for accurately carrying out the in situ heating of a targeted tissue. Small implants are employed with the targeted tissue which exhibit an abrupt change of magnetic permeability at an elected Curie temperature. The permeability state of the implant is monitored utilizing a magnetometer. The implants may be formed as a setpoint temperature determining component combined with a non-magnetic heater component to enhance the tissue heating control of the system. With the system, a very accurate quantum of heat energy can be supplied to a neoplastic lesion or tissue carrying infectious disease so as to maximize the induction of heat shock proteins. The system also may be utilized in conjunction with non-magnetic arterially implanted stents for the hyperthermia therapy treatment of restenosis and in conjunction with the mending of boney tissue.
APPROACHES TO THE SEARCH OF THE OPTIMUM PACKAGING OF EYE DROPS

The purpose of this study is to find a unique ophthalmic packaging that takes into account modern requirements for both maintaining the quality and safety of the drug, compliance with therapy, and increasing the profitability and environmental friendliness of its production. Statistics from open international databases on drugs approved for ophthalmic therapy in 2022 are provided. The research criteria were a valid registration status, the type of packaging and the presence of a preservative in the composition of the eye drops. The results of statistical processing of databases of ministries of health of different countries have shown the relevance of monodose ophthalmic packaging, capable of long-term storage of the drug without preservatives. In many countries, particularly in Europe, many drugs in the form of a monodose containers are registered. On this basis, a unique aluminum-based monodose container design is proposed, eliminating the use of large quantities of plastic.

The controllability of infinite quantum systems

Quantum phenomena of interest in connection with computation and communication often deal with transfers between eigenstates. For systems having only a finite number of states, the quantum evolution equation is finite-dimensional and the results on controllability on Lie groups as worked out decades ago provide most of what is needed in so far as controllability of dissipationless systems is concerned. However, for infinite-dimensional evolution of quantum systems, many difficulties, both conceptual and technical, remain. In this paper we organize some recent results from the physics literature in control theoretic terms and emphasize the type of analysis needed to go beyond what basic differential geometry can provide. In particular, we analyze from a controllability point of view the important results of Law and Eberly, and discuss the problem of controllability of quantum systems subject to the constraint that the trajectories must lie in pre-defined subspaces. The study of this problem is motivated by recent work on the design of quantum computers that avoid loss of coherence by operating in decoherence free subspaces.
Commentary on Matrix Factorizations and Applications

One of the fundamental tenets of numerical linear algebra is to exploit matrix factorizations. Doing so has numerous benefits, ranging from allowing clearer analysis and deeper understanding to simplifying the efficient implementation of algorithms. Textbooks in numerical analysis and matrix analysis nowadays maximize the use of matrix factorizations, but this was not so in the first half of the 20th century. Golub has done as much as anyone to promulgate the benefits of matrix factorization, particularly the QR factorization and the singular value decomposition, and especially through his book Matrix Computations with Van Loan [28]. The five papers in this section illustrate several different facets of the matrix factorization paradigm.
Uterine Evaluation Using Morphological Uterus Sonographic Assessment Diagnostic Protocol: A Literature Review

Background: Myometrial lesion is one of the major causes of the need for gynecologic surgeries. Ultrasonography (USG) is the primary modality in myometrial radiological examination. Thus a consistent procedure for reporting evaluation findings is needed. Method: We reviewed literature from textbooks and journals from 2000 to 2019 containing information about myometrial sonographic evaluation. Results: MUSA (Morphological Uterus Sonographic Assessment) is a consensus statement on terms, definitions, and measurements that may be used to describe findings and report the sonographic features of the myometrium using gray-scale sonography, colour/power Doppler and three-dimensional (3D) ultrasound imaging. The procedure consists of reports on the sonographic features of the uterine corpus, myometrium, and myometrial lesion. Conclusion: The need for a standardized terminology to describe sonographic findings of the myometrium, both normal and pathological, has given this protocol an advantage to show its benefit, that is not only just for a clinical background but also research purposes. We suggest researchers and clinicians continue to develop further and study the relevance and use of the consensus, especially the correlation of sonographic findings with clinical and histological features.
Resolved versus parametrized boundary-layer plumes

The aim of this study is to present a new methodology to compare LES resolved and large-scale parametrized thermals. A conditional sampling based on the combination of a passive tracer emitted at the surface and thermodynamic variables is proposed to qualify the organized structures in cloud-free and cloudy boundary layers. The sampling is validated against more traditional samplings of clouds or dry thermals. It enables to characterize convective updrafts from the surface to the top of the boundary layer (or the top of cumulus clouds) describing in particular the transition from the sub-cloud to the cloud layer. It retrieves plume characteristics, entrainment and detrainment rates, variances and fluxes. With this sampling, the contribution of boundary-layer thermals to fluxes and variances is analyzed in the subcloud and cloud layer.
Distributed containment control of networked uncertain MIMO pure‐feedback nonlinear systems via quantized state feedback and communication

This article presents a distributed adaptive containment control strategy using quantized state feedback and communication for uncertain multiple‐input‐multiple‐output pure‐feedback nonlinear multi‐agent systems with state quantization. It is assumed that quantized state variables of multiple followers and quantized outputs of multiple dynamic leaders are only available for constructing local adaptive feedback controllers of followers under a directed network. Compared with existing containment control approaches, the primary contribution of this study is dealing with discontinuously quantized state feedback and communication problems for containment control design in the presence of unknown nonaffine nonlinearities. Based on quantized state and communication information, local adaptive neural network trackers of followers and their adaptive tuning laws are developed to guarantee that the trajectories of all followers converge to the dynamic convex hull spanned by the multiple leaders regardless of unknown pure‐feedback nonlinearities. By analyzing the stability of the local quantization errors between quantized signals and original signals, we prove the boundedness of all closed‐loop signals and the convergence of the containment errors to a sufficiently small domain around the origin. Simulation examples involving flexible‐joint manipulators are presented to validate the proposed quantized feedback scheme.
CARIES ASSOCIATED WITH RESTORATIONS IN PRIMARY MOLARS –AN 18-MONTHS FOLLOW-UP STUDY

Objective: To investigate the occurrence of caries associated with restorations in primary molars. Methods: Resin-modified glass ionomer cement (n=50) and compomer (n=50) restorations of primary molars were made in 100 children. The restorations were clinically evaluated on the 3rd, 6th, 12th and 18th month with the FDI criteria. Results: On the 3rd month recall, all restorations showed excellent clinical assessment scores for all FDI criteria. In regard to secondary caries, on the 6th month, clinically unacceptable was only one restoration. In the 12th month, 19.00% of the restorations were diagnosed with caries adjacent to the restoration. The relative share of secondary caries lesions assessed in restorations from glass ionomer cement (27.27%) was higher than that from compomer material (14.28%), as well as the restorations on the occlusal surface (38.46%), compared to those on the proximal surfaces (7.40%). Caries associated with restorations was diagnosed more frequently in relation to the caries lesions assessed as active at the first visit (29.62%) compared to the inactive lesions (7.69%). At the 18th month recall, the relative share of restorations diagnosed with secondary caries was lower (8.00%). Conclusion: The type of restorative material, type of affected surface and the activity of the carious lesion are factors that may influence the occurrence of caries associated with restorations in primary molars. Our study showed that a critical moment for the clinical condition of the followed restorations is the 12th month of the treatment.
Mobilité atomique dans les silicates vitreux et fondus

Cette these traite de la diffusion couplee dans un systeme verrier industriel contenant quatre oxydes (SiO2, Al2O3, CaO, Na2O). La gamme de temperatures consideree s’etend de la transition vitreuse (650°C) au liquidus (1200°C). Les premiers resultats concernent la nature macroscopique de la diffusion. La matrice des coefficients de diffusion permet de quantifier la mobilite des composants et met en evidence de nombreuses interactions entre eux. D’autres informations sont obtenues a l’echelle microscopique. Les equations d’echanges synthetisent les principaux chemins de diffusion suivis au sein du systeme sous la forme de reactions. L’ensemble des donnees de la litterature est traite et semble converger vers des chemins de diffusion preferentiels. Des hypotheses sur les mecanismes de la diffusion des especes sont proposees. Les resultats obtenus a basse temperature permettent de discuter les liens entre proprietes de transport et diffusion. L’etude de la structure du materiau s’est appuyee sur la spectroscopie Raman. Les experiences de diffusion donnent acces a un grand nombre de compositions verrieres, permettant ainsi de developper un outil statistique de traitement des spectres. Les composantes spectrales ainsi obtenues sont discutees a la lumiere des nombreuses observations decrites dans la litterature. Cette demarche permet egalement d’interpreter les composantes au travers des correlations entre leurs intensites relatives et la composition du materiau ainsi qu’en etudiant leur evolution le long des profils de diffusion. La possibilite de faire de la spectroscopie Raman une technique de quantification des especes est discutee.
Searching for New Human Behavior Model in Explaining Energy Transition: Exploring the Impact of Value and Perception Factors on Inconsistency of Attitude toward Policy Support and Intention to Pay for Energy Transition

The purpose of this study is to compare and analyze the factors influencing the public’s attitude toward policy support and intention to pay for energy transition from nuclear to renewable energy. We focus on inconsistency issues between attitude and intention. To this end, we set the attitude toward policy support and behavioral intention to pay as dependent variables, and value factors (i.e., ideology, political support for the current Moon Jae-in government, environmentalism, and science-technology optimism) and perception factors (i.e., perceived risk, benefit, knowledge, and trust) as the independent variables. Based on a survey, the analysis showed that at the variable level, the perceived benefits and trust in renewable energy and perceived risks and benefits in nuclear energy influenced the attitude toward policy support and the intention to pay for energy transition. Second, when evaluating the explanatory power of independent variables, the attitude toward the energy transition was affected in the following order: (1) perceived benefit in nuclear power (β = 0.259) > (2) perceived benefit in renewable energy (β = −0.219) > (3) perceived risk in nuclear energy (β = 0.202) > (4) Moon Jae-in government support (β = 0.146). On the other hand, behavioral intention to pay for energy transition was influenced in the following order: (1) trust in renewable energy (β = 0.252) > (2) Moon Jae-in government support (β = 0.154) > (3) perceived risk in nuclear energy (β = 0.139) > (4) perceived benefit in renewable energy (β = 0.099). Third, variables such as environmentalism, perceived benefit/risk/trust in renewable energy, and perceived benefit/risk in nuclear energy affected inconsistency between attitude toward policy support and intention to pay for energy transition.
An Almost Contact Structure on $G_2$-Manifolds

In this article, we study an almost contact metric structure on a $G_2$-manifold constructed by Arikan, Cho and Salur in via the classification of almost contact metric structures given by Chinea and Gonzalez. In particular, we characterize when this almost contact metric structure is cosymplectic and narrow down the possible classes in which this almost contact metric structure could lie. Finally, we show that any closed $G_2$-manifold admits an almost contact metric $3$-structure by constructing it explicitly and characterize when this almost contact metric $3$-structure is $3$-cosymplectic.
Localized wave solutions of the scalar homogeneous wave equation and their optical implementation

In recent years the topic of localized wave solutions of the homogeneous scalar wave equation, i.e., the wave fields that propagate without any appreciable spread or drop in intensity, has been discussed in many aspects in numerous publications. In this review the main results of this rather disperse theoretical material are presented in a single mathematical representation - the Fourier decomposition by means of angular spectrum of plane waves. This unified description is shown to lead to a transparent physical understanding of the phenomenon as such and yield the means of optical generation of such wave fields.
Eigenvalue bounds for matrix pencils

whereb is an upper bound of the (finite) eigenvalues of (1). Then (1) is asymptotically stable if and only if for symmetric positive definite matriceŝQ = Q̂ > 0 there are always symmetric, positive definite solution matrices P̂ = P̂ > 0 of (2). The main assumption for this result is the à priori knowledge of an upper bound b of the eigenvalues. For the classical eigenvalue problem withE = In (identy matrix) it is well-known that b = ||A|| represents such an upper bound where each norm can be applied. But what bound exists for matrix pencils (1)?
Exploring the Mechanism of Realgar against Esophageal Cancer Based on Ferroptosis Induced by ROS-ASK1-p38 MAPK Signaling Pathway

Background Realgar (REA), a Chinese herbal decoction, has been used to treat various tumors and has produced positive outcomes; however, there is a lack of convincing evidence for the treatment of esophageal cancer. The present study aimed to investigate the effects of REA on esophageal cancer (EC) and explore its mechanism. Methods EC cells Eca109 and KYSE150 were selected for this study, and different groups of treated cells were set up. We studied the inhibition rate and half inhibition concentration (IC50) by CCK-8 method, the clone formation assay was used to detect the clone formation ability, the scratch assay is used to determine the cell migration ability, the Transwell assay was used to detect the cell invasion ability, the protein expressions of E-cadherin, Slug, N-cadherin, ASK1, p38 MAPK, p-p38 MAPK, and GPX4 were determined using Western blot, the mRNA expressions of ASK1 and p38 MAPK were assessed using qRT-PCR, transmission electron microscopy was used to observe the cellular ultrastructure, Prussian blue staining was used to observe the intracellular iron particle distribution, and biochemical analysis of cellular MDA, SOD, GSH, and GPXS activities, flow cytometric analysis of cellular ROS levels, immunofluorescence staining to detect cellular GPX4 expression, and JC-1 method to detect mitochondrial membrane potential were used. Results REA inhibited the proliferation of Eca109 and KYSE150 cells in a time- and concentration-dependent manner, and REA significantly inhibited the migration and invasion of Eca109 and KYSE150 cells and activated the cellular ferroptosis and ROS-ASK1-p38 MAPK signaling pathways (P < 0.05). Inhibition of activation of the ROS-ASK1-p38 MAPK signaling pathway promoted the inhibition of proliferation, migration, and invasion of Eca109 and KYSE150 cells and the induction of ferroptosis by REA. Conclusion REA induced ferroptosis and inhibited the migration of EC cells by activating the ROS-ASK1-p38 MAPK signaling pathway.
