We examine the stability of a highly viscous and thin Newtonian liquid sheet that is heated as it is drawn onto a moving substrate. In a previous paper, Ng and Weinstein [“Enhanced suppression of draw resonance in sheet casting due to heating,” Phys. Fluids 37, 044107 (2025)] reported a significant suppression of the draw resonance instability in this heating configuration; a representative viscosity/temperature dependence for glass was used in their theoretical model. Compared with an isothermal configuration, the critical draw ratio—defined as the maximum ratio of the final to initial velocity in the sheet below which the sheet is stable—was increased by many orders of magnitude when a portion of the sheet experienced a Gaussian heating profile. Internal and external heat transfer resistances were also considered, and the parameter space of enhancement was quantified. The prior study, however, incorporated only viscous forces in the flow model. Here, we consider the effects of inertia, surface tension, and gravity on the significant stabilizing effects observed by Ng and Weinstein due to heating. We find that fluid inertia further stabilizes the heated liquid sheet at surprisingly small Reynolds numbers, while surface tension and gravitational effects have quantitative but relatively minor effects. For the typical glass viscosity/temperature model used here, however, inertial stabilization cannot be realized in practice, and the prior conclusions of Ng and Weinstein regarding the enhanced suppression of instability by heating are largely unchanged.

We apply the complex-scaling method (CSM) to the α + α + N three-body model to study the nuclear structure of Be 9 and B 9 nuclei, focusing mainly on mirror symmetry in the resonant states. In our previous paper [], we reported the energy-level structure below about 15 MeV excitation energy in Be 9 and B 9 nuclei and discussed the significant effect of the Coulomb force. In this paper, we investigate the wave functions of these states, i.e., the matter- and charge-distribution radii, and the cluster-channel amplitudes. The results show a clear mirror-symmetry breaking between Be 9 and B 9 nuclei, which is mainly due to the Coulomb interaction.

According to CIGRE, the usual arrangement of electrodes in a shoreline electrode station for HVDC interconnections is straight with the following form: forming straight frames with the electrodes at equal distances and placing the frames parallel to the longitudinal axis of the breakwater, successively at fixed distances between them. In a previous paper by the authors, 10 alternative configurations of placement of such straight frames were examined to determine which placements mainly affect the near-field results. In particular, radial or circumferential arrangements of the straight frames on a central base in the open sea improve the overall field results, such as the absolute potential and electrode station resistance to remote earth, satisfying the requirements of the maximum electric field strength. In this paper, the nonlinear configuration of the frames will be studied from an electric field perspective at the level of a preliminary study forming innovative configurations in order to check their suitability with respect to the relevant requirements of the CIGRE guidelines B4.61/2017. These arrangements, located in electrode stations, are evaluated and compared with the older configurations for two cases, those of Korakia in Crete and Stachtoroi in Aegina, Attica, for the HVDC Crete-mainland Greece interconnection of 1 GW, ±500 kV.

ABSTRACT This paper explores what starting from a position of intracon- nection means in PC practice. It builds on my previous paper in this journal on the illusion of separateness to suggest the practice implications of this approach. I consider the implications of intraconnection for the concept of autonomy and argue for a concept of relational autonomy and the importance of homonomy. I argue that non- directivity does not mean that the therapist keeps out of the relationship and only responds to the client’s expressions. Instead, this requires an emotionally responsive therapist, willing to be present and open to transformation with the client. This necessitates courage and an ongoing commitment to self and intersubjective awareness. I focus on integrity and the meaning of this in relation to congruence in the therapy relationship, which involves awareness of the societal and cultural context of this relationship. Our increasing congruence is a lifelong process of learning, coupled with humility and a not- knowing stance. This enables presence which is the condition for encounter.

We present an improved algorithm based on the POlarization LIdar PHOtometer Networking (POLIPHON) method to retrieve cloud condensation nuclei (CCN) concentration profiles from spaceborne lidar observations. Our previous paper, which was the first study to demonstrate the feasibility of using measurements from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) to retrieve CCN is revisited. Our results focus on the Evaluation of CALIPSO’s Aerosol Classification scheme over Eastern Mediterranean (ACEMED) research campaign that took place over Thessaloniki, Greece, in September 2011. We compare our results with our earlier retrievals, discussing the critical changes that have been made and the importance of using the proper conversions factors. We also demonstrate the use of conversion factors acquired based on CALIPSO aerosol typing for CCN retrievals. The analysis highlights the strong influence of smoke on CCN concentrations and shows that the assumed aging state of the smoke can significantly alter the retrieval outcome.

In a previous paper, we proposed a symplectic version of the Brezis–Ekeland–Nayroles principle based on the concepts of Hamiltonian inclusions and symplectic polar functions. We applied it to the standard plasticity. The object of this work is to extend the previous formalism to non-associated plasticity. For this aim, we generalize the concept of bipotential to dynamical systems. The keystone idea is to define a symplectic bipotential. We present a method to build it from a bipotential. Next, we generalize the symplectic Brezis–Ekeland–Nayroles principle to the non-associated dissipative laws. We apply it to the non-associated plasticity and to the unilateral contact law with Coulomb’s dry friction.

The measurement of acoustic performance of underwater panels, such as their reflection and transmission coefficients, has always been a challenge. The finite size of the tank imposes a low frequency limit, while diffraction by the edges of the panel disturbs measurements. Despite these difficulties, it remains a valuable tool for comparison with numerical and analytical studies. In a previous paper [Roux, Pouille, Audoly, and Hladky, J. Acoust. Soc. Am 147(2), 1104-1112 (2020)], the three-point method has been proposed and tested on a homogeneous panel. The present paper proposes an extension of the method applicable to periodic metamaterials. First, the applicability and robustness of the three-point method are tested on a periodic panel. Then, since it behaves like a diffraction grating, above the grating cut-off frequency, the measurement method must separate the specular wave from the other propagative contributions. For that purpose, the five-point method is proposed as a solution to separate these contributions to retrieve the reflection and transmission coefficients. The three- and five-point methods are applied to a test panel made of steel bars. Limitations on these methods are discussed and a solution is proposed to reduce their impact. Finally, a correct measurement-simulation agreement is observed for the reflection and transmission coefficients for both the specular and the first-propagative diffraction order.

In a previous paper, we showed in children 6-12 years old that a resting-state (RS) eyes-open dark room (DR) task provides RS parietal-occipital alpha measures similar to those obtained using the standard RS eyes-closed (EC) exam. Results provided initial evidence that theRS DR procedure is feasible and useful with populations often excluded from electrophysiology RS studies, such as participants who cannot remain awake with their eyes closed or cannot remain still for an extended period. The present study extended the DR and EC comparisons to a much larger sample of children spanning a wider age range and expanded the analysis strategy to examine RS aperiodic measures (offset and slope [exponent] of the power spectrum) and to evaluate 15 distinct brain regions rather than just the previously examined parieto-occipital RS periodic alpha activity. RS activity was recorded using MEG, here reporting on 147 DR and EC datasets obtained from children (including 23 with evaluable datasets at multiple timepoints) with typical development (TD; N = 69) and children with autism spectrum disorder (ASD; N = 53) 7.7-17.1 years old. Findings showed good reliability in both TD and ASD for the EC and DR parietal-occipital peak alpha frequency (frequency with highest alpha power; interclass correlation [ICC] = 0.84, p < 0.001). The ICC for periodic parieto-occipital PAF power was lower (ICC = 0.65). For offset and exponent, the two RS aperiodic measures, fair to good reliability for both groups was observed between DR and EC at all 15 brain regions (mean and median ICC values 0.77-0.80). Offset and exponent values differed significantly across the 15 brain regions, as did associations between age and both aperiodic measures. Findings confirm that the DR exam is a viable way to obtain RS periodic and aperiodic measures. The lack of TD/ASD differences in the EC and DR periodic and aperiodic ICCs supports the generalizability of the DR procedure. Finally, regional differences in aperiodic measures demonstrate the need to assess aperiodic activity in brain source space rather than scalp sensor space.

Abstract In this paper, we continue the research on the power of contextual grammars with selection languages from subfamilies of the family of regular languages. In the past, two independent hierarchies have been obtained for external and internal contextual grammars, one based on selection languages defined by structural properties (finite, monoidal, nilpotent, combinational, definite, ordered, non-counting, power-separating, suffix-closed, commutative, circular, or union-free languages), the other one based on selection languages defined by resources (number of non-terminal symbols, production rules, or states needed for generating or accepting them). In a previous paper, the language families of these hierarchies for external contextual grammars were compared and the hierarchies merged. In the present paper, we compare the language families of these hierarchies for internal contextual grammars and merge these hierarchies.

In the previous paper, we constructed two kinds of edge contractions for the affine super Yangian and a homomorphism from the affine super Yangian to the universal enveloping algebra of a $W$-superalgebra of type $A$. In this article, we show that these two edge contractions commute with each other. As an application, we give a homomorphism from the affine super Yangian to some centralizer algebras of the universal enveloping algebra of $W$-superalgebras of type $A$. Using the edge contraction, we also show the compatibility of the coproduct for the affine super Yangian with the parabolic induction for a $W$-superalgebra of type $A$ in some special cases.

Abstract We consider a finite analytic morphism $$\varphi =(f,g)$$ φ = ( f , g ) defined from a complex analytic normal surface ( Z , z ) to $$\mathbb {C}^2$$ C 2 . We describe the topology of the image by $$\varphi $$ φ of a reduced curve on ( Z , z ) by means of iterated pencils defined recursively for each branch of the curve from the initial one $$\langle f,g \rangle $$ ⟨ f , g ⟩ . This result generalizes the one obtained in a previous paper for the case in which ( Z , z ) is smooth and the curve irreducible. The methods we use also permit us to describe the topological type of the discriminant curve of $$\varphi $$ φ , in particular, the topological type of each branch of the discriminant can be obtained from the map without previous knowledge of the critical locus.

This paper explores the implementation of a hypothetical programming language, it is an extension of a previous paper by the same author of a compiler implemented in C programming language using tools “flex” and “bison” for lexical analysis and parsing. In contrast to that paper, an interpreter presented here was developed exclusively using a standard library of Go programming language without relying on any other tools or existing code.

Abstract Starting from a generic Lagrangian, we discuss the number of propagating degrees of freedom in the framework of generalised non-linear electrodynamics when a photon-background split is applied. We start by stating results obtained in a previous paper, before modifying the action to an equivalent form. Within this new formulation, we highlight the presence of an effective mass and consider the mechanical reduction of the model to ensure the positivity of said mass. We then study the constraint algebra of the model and show that we shift from a model with two first-class to two second-class constraints, which implies the propagation of an additional degree of freedom. We also show that the Hamiltonian is bound from below and thus does not suffer from Ostrogradski-type instabilities. We conclude by deriving the propagator for the model, and discussing the potential link between the nature of this additional polarisation and the mechanism behind the effective mass generation in this class of models.

Hypertension (HTN) is the most prevalent risk factor for severe cardiovascular disease and can cause major renal damage, inflammation, and immune cell accumulation. Lymphatic endothelial cells (LECs) are involved in the removal of pro-inflammatory immune cells and cytokines and kidney-specific augmentation of lymphangiogenesis can prevent or reduce HTN. In our previous paper, we performed single-cell RNA sequencing (scRNAseq) on CD31+/podoplanin+ renal cells from mice that underwent angiotensin II-induced (A2HTN) or salt sensitive (SSHTN) models of HTN (and their respective controls) and identified populations of LECs, myeloid immune cells (MICs), and a novel multipotent population we dubbed support cells (SCs). Using NicheNet, we compared baseline signaling between these three cell types in control samples and differences in signaling between control and HTN samples in both LECs and SCs. Ligands with high regulatory potential were identified for all three cell types, with Tgfb1 having the strongest and most consistent activity across all cell types. When comparing control and HTN samples in both LECs and SCs, HTN samples consistently had a larger number of downstream targets enriched and targets that were enriched in HTN samples also corresponded to significantly increased differentially expressed genes (p<0.01) as reported previously. Significant GO terms (p<0.01) were identified from targets and showed a shift in HTN samples away from homeostatic processes and toward growth and proliferation in LECs and translation and metabolism in SCs. Validation and manipulation of the ligand-receptor-target links identified here may provide novel approaches to reduce renal inflammation and immune cell activation.

In this paper, we suggest a new approach to study minimal surfaces of general type with p g = 0 p_g=0 via their Cox rings, especially using the notion of combinatorially minimal Mori dream space introduced by Hausen [Mosc. Math. J. 8 (2008), pp. 711–757, 847]. First, we study general properties of combinatorially minimal Mori dream surfaces. Then we discuss how to apply these ideas to the study of minimal surfaces of general type with p g = 0 p_g=0 which are very important but still mysterious objects. In our previous paper [Adv. Math. 347 (2019), pp. 708-738], we provided several examples of Mori dream surfaces of general type with p g = 0 p_g = 0 and computed their effective cones explicitly. In this paper, we study their fibrations, explicit combinatorially minimal models and discuss singularities of the combinatorially minimal models. We also show that many minimal surfaces of general type with p g = 0 p_g=0 arise from the minimal resolutions of combinatorially minimal Mori dream surfaces.

Purpose The present article investigates the theoretical orientations of public relations educators and their implications for public relations pedagogy. Building on previous research that revealed a lower perceived value of public relations higher education (HE) degrees compared to non-specialist degrees and professional training offered by member organisations, this study explores the theoretical perspectives of European public relations educators on dominant public relations paradigms, relevant theories and the most commonly used methodologies in public relations research. Design/methodology/approach The present study has an exploratory nature, as such a research study has not yet been conducted at the national or regional levels. In order to identify the public relations educators’ theoretical orientations, various data have been preliminarily collected from the study respondents through a questionnaire. For the first time in a research study, public relations practitioners who are hourly contracted by universities to teach on public relations degrees have been included in the survey. Lastly, we expanded the survey at the European level, as many of the previous studies have focused on a national level. Findings In terms of paradigmatic dominance, the normative understanding of public relations as management of communication is the most extended amongst our respondents, while we could see that critical and cultural perspectives of public relations are developed in media relations courses. The subsequent theory of the normative and functionalist paradigm, the excellence theory, is indeed the most taught by our respondents, with new terms such as “strategic communication” being currently proposed as a natural transition from public relations. Lastly, regarding the research methods being developed in academic research, interviews and case studies have emerged as the most used by our respondents. Such key findings are nuanced and then discussed from the perspective of the value of public relations higher education degrees. Originality/value Our article is an original contribution to the public relations and strategic communication scholarship, which investigates the institutional manifestations and subsequent pedagogies. We started from a critical national situation of public relations degrees discussed in a previous co-authored paper, where we enquired into the current dynamics in the United Kingdom, to then focus on public relations educators’ theoretical orientations in order to assess the quality of teaching within higher education degrees. Developing the present study at the European level is also a major contribution, as many previous studies have only presented national cases.

Hypertension (HTN) affects over one billion people worldwide and can lead to debilitating cardiovascular and renal conditions if left untreated. Cell death in the kidneys and the inflammation that follows are among the primary effects of chronically elevated blood pressure. There are several cell types throughout the body with immunomodulatory, anti-inflammatory, and pro-regenerative properties that support tissue homeostasis and recent studies have highlighted their therapeutic potential in HTN and kidney-related conditions. In our previous paper, we found a pool of multipotent nephron-associated support cells (SCs) in single-cell RNA sequencing samples of CD31+ and podoplanin+ cells taken from the kidneys of hypertensive mice generated through two mouse models of HTN. Despite remaining roughly constant in number between HTN and control groups, these SCs had 299 differentially expressed genes (p<0.01), 51 and 86 enriched pathways (p<0.01) in the M2 and M5 Molecular Signatures Database gene sets, respectively, and 180 HTN-specific regulons. We also compared lymphatic endothelial cells (LECs) and SCs from HTN and control groups and identified 3636 differentially expressed genes (p<0.01), 537 M2 and 415 M5 enriched pathways (p<0.01), and 218 LEC-specific and 227 SC-specific regulons in the HTN samples. SCs from mice with HTN were more resistant to inflammation-induced changes compared to LECs, and had downregulated stem cell suppressive genes and upregulated genes related to stem cell proliferation and regeneration.

Purpose This study analyzes inter-industry reversal, or whether loser or underperforming industries yield higher returns than winner or outperforming industries in Latin America. The phenomenon is likewise examined in market segments that are more prone to inefficiencies and short-selling barriers. It also investigates intra-industry reversal by assessing whether loser stocks outperform winner stocks within the same industry. The analysis is then extended to market segments defined by stock characteristics. Design/methodology/approach Long-term reversal for industry portfolios is evaluated following the portfolio simulation approach proposed by Jegadeesh and Titman (1993). When testing multiple hypotheses simultaneously, the probability of reporting false positives increases substantially. To account for multiple hypothesis testing, p-values are adjusted using several well-established approaches. Findings No evidence of inter-industry reversal for the whole market or for specific market segments was found. Moreover, in both the entire market and certain segments, a contrarian intra-industry reversal strategy does not yield profits. Overall, investors in Latin American industries would have been unable to profit from exploiting return reversion across and within industries in the region. Research limitations/implications The study focuses on formation periods of up to five years and holding periods of up to a year, as constrained by data availability. This limitation restricts the range of reversal strategies that can be analyzed (e.g. formation periods of a decade are not considered). As additional data become available, this limitation will be less severe. Practical implications This paper builds on our previous paper that explored industry return continuation or momentum. Overall, neither momentum nor reversal at the industry level appears to be significant in Latin America's most important equity markets. Violations of weak-form market efficiency at the industry level in Latin America are not supported by our findings. Originality/value This paper contributes by providing new evidence on both inter- and within-industry reversal in a region that is frequently overlooked in international studies. It also adds to the literature by analyzing reversal in market segments related to industry and stock characteristics such as size or market cap. In addition, the study addresses the issue of multiple hypotheses testing, which is often neglected in existing literature.

In a previous paper, we explored, in the context of the category $ \mathcal{L_M} $ of complete modular lattices and linear morphisms introduced by T. Albu and M. Iosif, the lattice-theoretic counterparts of semi-projective retractable modules and their ring of endomorphisms. In this work, we investigate the dual situation. That is, we introduce the concept of semi-injective coretractable lattices, and we study their relation to their monoid of endomorphisms.
