Stationary scattering for the nonlinear Schrödinger equation with point-like obstacles: exact solutions
Authors: Mirón M. , Sadurní E. 
Published: October 2024

Abstract
We solve the Nonlinear Schrödinger Equation (NLSE) in 1D in presence of one, two and several Dirac delta potentials. With the help of an equivalent central force problem we obtain the analytical solutions in terms of a biparametric family containing the Jacobi functions. Elliptic Jacobi functions are already reported in the literature but they have not been used in the context of a scattering problem under causal boundary conditions. In the simplest examples of one or two Dirac deltas we analyze how the nonlinear term of the equation affects the modulus and phase profiles of the wave function. We also study the transmission curves under the nonlinear modification of the tunneling behavior for the first time. For a Fabri-Perot configuration made of two deltas, we obtain the effect of nonlinear coupling in the positions of the local maxima (resonances). We lay the foundations for nonlinear Anderson localization of 1D BECs in a speckle field. Upon redefinition of parameters these novel results describe the dynamics of a stationary Higgs field in 1D. Finally, we discuss the conditions for soliton formation under the influence of a Dirac comb potential, giving rise to fully correlated locations and intensities of the defects.

Published: October 2024

AbstractWe study the effect of the diffusion of digitalization, measured as the level of expenditures in digital technologies, on labor demand within the manufacturing sector. We exploit unique information from a focus study of the quarterly survey of Unioncamere Piemonte (one of Italy’s most industrialized and technologically advanced regions) to measure the extent to which planned digital technologies investments impact hiring propensity, differentiated by educational level. Based on a representative sample of non-micro firms, our findings suggest a positive relationship between digital investments and the probability of hiring highly educated workers, mainly driven by the demand for individuals with a post-secondary technical institute (ITS) diploma and post-MSc qualifications or a PhD in STEM fields. Conversely, we also find that digital investments negatively influence the probability of hiring low-educated individuals, primarily referring to the demand for workers with secondary education. Our results reveal firms’ human capital upscaling dynamics powered by digitalization processes.
What the States of Truthmaker Semantics Could (Not) Be
Authors: Silva Francisca 
Published: October 2024

AbstractDevelopments in truthmaker semantics for the most part stay clear of the metaphysical issue of what sort of entities serve as the truthmakers and falsitymakers for sentences. It is assumed that perhaps facts or states of affairs (Fine 2017a; Jago 2020), with these taken sometimes as concrete particulars (Hawke 2018) could serve for the job, but nonetheless that some such entities would do. In this paper I take a closer look at the issue of what entities could or could not play the role of truthmakers and falsitymakers in standard truthmaker semantics (Fine 2016, 2017a, b; Fine and Jago 2019), based on desiderata imposed by metaphysical and semantic considerations.

AbstractThis study utilized a dataset comprising 3023 lactation records for Friesian cows, 596 records for Native cows (Baladi), and 1189 records for Crossbred cows spanning from 1994 to 2015. The objective was to estimate and assess genetic and phenotypic parameters and breeding values for 305-day milk yield (305-DMY), lactation period (LP), calving interval (CI), and days open (DO) within the Egyptian dairy context. The motivation for this research stemmed from the need to understand the genetic potential of different cattle genotypes in Egypt and identify opportunities for enhancing dairy production. Data were analyzed using the linear mixed model least squares and maximum likelihood (LSMLMW) and multiple-trait derivative-free restricted maximum likelihood (MTDFREML) programs. The analytical model included fixed effects such as season and year of calving, parity, and genotype groups, while random effects included animal and error. Unadjusted means for 305-DMY, LP, CI, and DO were calculated for each genotype group. Genotype groups significantly impacted all studied traits. Heritability estimates varied across genotype groups, with higher estimates observed in Crossbred (0.32, 0.26, 0.25, 0.23) and Native cows (0.26, 0.28, 0.28) compared to Friesian cows (0.24, 0.22, 0.16, 0.17) for productive and reproductive traits, respectively. Genetic correlations among traits ranged from 0.10 to 0.86 for the three genotype groups, while corresponding phenotypic correlations were generally small to moderate and positive. Regarding breeding values, the accuracy estimates suggested that both sires and cows could contribute to genetic improvement. This indicates the potential for enhancing dairy production through selective breeding strategies.

AbstractGas quenching and vacuum quenching process are widely applied to accelerate solvent volatilization to induce nucleation of perovskites in blade-coating method. In this work, we found these two pre-crystallization processes lead to different order of crystallization dynamics within the perovskite thin film, resulting in the differences of additive distribution. We then tailor-designed an additive molecule named 1,3-bis(4-methoxyphenyl)thiourea to obtain films with fewer defects and holes at the buried interface, and prepared perovskite solar cells with a certified efficiency of 23.75%. Furthermore, this work also demonstrates an efficiency of 20.18% for the large-area perovskite solar module (PSM) with an aperture area of 60.84 cm2. The PSM possesses remarkable continuous operation stability for maximum power point tracking of T90 > 1000 h in ambient air.
Sustainable operation of large scale heat pumps in cogeneration dominated district heating networks
Authors: Hurst Georg , Jentsch Andrej , Blesl Markus 
Published: October 2024

AbstractLarge scale heat pumps (LSHP) have seen a rapid proliferation in recent years, with projects and initiatives aimed at integrating electrically driven LSHP into existing district heating networks (DHN). The financial advantages have driven most LSHP installations to be powered by electricity generated by on-site cogeneration (CHP), given CHP’s dominant role in DHN. This LSHP + CHP combination poses the question, to what extent ecological improvements, measured as a reduction in specific CO2 emissions through LSHP operation can be achieved, contingent on the source of electricity and heat source employed. In this paper, the LSHP + CHP combination was generally analysed under usage of exergy analysis and a 2nd law derived method is presented. This method allows to evaluate the magnitude of CO2 reduction through LSHP operation across all common heat sources in 1st to 4th generation DHNs in conjunction with CHP. Results show, that in LSHP + CHP combination, heat from LSHP using either of the 2 heat sources ambient air or surfaced water, inevitably comes with higher specific CO2 emissions over the CHP heat. Only when using a sufficiently hot and emissions-free heat source, the LSHP heat from a LSHP + CHP combination can yield to an annual best case of half the CO2 emissions of the CHP. Importantly, the choice of power source has a far more significant impact, as LSHP powered by electricity from renewable energy sources achieve more than an eight-fold reduction in emissions compared to the LSHP + CHP combination. Therefore, power consumption with sufficiently low specific CO2 emissions out of external source is imperative to fully realize the ecological benefit of LSHP in DHN, underlining that the successful heat transition through LSHP relies heavily on the transformation of the electricity supply.

Published: October 2024

AbstractLatin American governments are increasingly adoptingmano durainitiatives to combat gangs, organized crime, and insecurity. Whilemano durahas been a concept of increasing empirical interest, there seems to be limited conceptual clarity about the wide spectrum of strategies developed to combat crime and associated fear. This article proposes a definition ofmano durathat has three different dimensions, each of them containing specific elements. The form ofmano duradepends on formal, informal, and rhetorical practices. Drawing on 46 scholarly works in the social sciences, we develop our definition anchored in the knowledge of Latin American policing strategies, contributions on responses to crime in the region, and the conceptual development literature. With the purpose of supplementing our effort to standardize the usage of the term with the need to retain a degree of conceptual differentiation, we also offer a stylized model to better classify policing strategies in Latin America. In our stylized model, the numerous ways policies and narratives as well as their implementation (or not) interact can be grouped into four broad categories:full mano dura,institutional mano dura,performative mano dura, andcovert mano dura.
Xenophobia in Juror Decision-Making
Authors: Huang Li 
Published: October 2024

Abstract
With the upsurge of anti-globalizing ideologies and politics, the increasing institutionalization of xenophobia within the legal system has emerged as a pressing concern. Existing law and social science research has underexplored xenophobic bias in the US legal system. This article conceptualizes xenophobic bias as consisting of racism and nationalism. It investigates whether mock jurors reach different verdicts on defendant companies from foreign countries of origin (Japan, France, and China) compared to domestic (US) companies. Using a test simulating a patent lawsuit, the research finds no evidence of general xenophobic bias in juror liability verdict decisions, yet there is a specific bias against the Chinese company when granting damage awards. The similarity-leniency effect that has been established in the previous literature is corroborated in this article. Additionally, political views moderate the effects of the company’s country of origin on juror decisions. This research offers a more nuanced conceptual framework of xenophobic bias in juror decision-making for future law and social science research and informs judicial policies seeking to improve jury instructions and jury selection to reduce xenophobic bias.

AbstractRuminants can recycle nitrogen (N) and phosphorus (P), which are essential for vital body processes. Reduced N- and P-intake in ruminants is desirable for economic and ecologic reasons. Simultaneous modulation of mineral homoeostasis and bone metabolism occurs in young goats. This study aimed to investigate potential effects of dietary N- and/or P-restriction on molecular changes in bone metabolism. The twenty-eight young male goats were fed a control diet, an N-reduced diet, a P-reduced diet or a combined N- and P-reduced diet for 6–8 weeks. The N-restricted goats had lower plasma Ca concentration and higher plasma osteocalcin (OC) and CrossLaps concentrations. The P-restricted goats had reduced plasma inorganic phosphate (Pi) concentrations and increased plasma Ca concentrations. Due to the initiation of a signalling pathway that inhibits the fibroblast growth factor 23 (FGF23) expression, this was lower with P-restriction. Consequently, lower Pi concentrations were the main factor influencing the reduction in FGF23. The changes in mineral homoeostasis associated with P-restriction led to a reduction in OC, bone mineral content and mineral density. Simultaneously, bone resorption potentially increased with P-restriction as indicated by an increased receptor activator of NF-κB ligand/osteoprotegerin (OPG) ratio and an increase in OPG mRNA expression. Additionally, the increased mRNA expression of the calcitonin receptor during P-restriction points to a higher number of osteoclasts. This study demonstrates an impairment of bone remodelling processes in young goats by N- or P-restriction. With P-restriction, bone mineralisation rate was potentially reduced and bone quality impaired, while with N-restriction, bone remodelling increased.

AbstractIntegrons are important genetic elements that allow easy acquisition and dissemination of antimicrobial resistance genes. Studies reporting occurrence of integrons in Staphylococcus aureus (S. aureus) isolated from bovine mastitis in large dairy farms across China are scarce. The aim of this study was to investigate the occurrence of class 1 integrons (intI1), antimicrobial resistance (AMR) and associated genes in S. aureus isolated from bovine mastitis and their associations. Minimum inhibitory concentrations (MICs) were determined to evaluate the AMR phenotypes, whereas PCR was carried out to assess the occurrence of AMR genes and intI1. In addition, index cluster analysis was used to estimate associations between AMR phenotype, genotype and intI1 in 103 isolates. Overall, 83% of S. aureus were intI1-positive and 5 types of gene cassettes were detected. Susceptibility against single antimicrobial agents ranged from 0% (erythromycin), 12% (ampicillin) and 16% (penicillin G) to 96% (gentamicin). Most isolates (64%) were intermediate-resistant against erythromycin, whereas resistance against ceftriaxone (22%), clindamycin (4%), cefotaxime (2%), tetracycline (1%) and ciprofloxacin (1%) were relatively uncommon. The predominant resistant gene was blaZ gene (n = 88, 85%) followed by tetD gene (n = 85, 83%). With an estimated prevalence of 12% of the mecA gene, methicillin-resistant S. aureus isolates had higher MIC50 and MIC90 for majority of antimicrobials than methicillin-susceptible S. aureus isolates. Presence of the ermC gene was associated with erythromycin resistance. Ampicillin, erythromycin and penicillin G resistance were associated with intI1. The data presented in our study indicated that class 1 integron-mediated resistance possibly plays an important role in dissemination of AMR in S. aureus isolated from bovine mastitis.
Frequency, perceptual salience, and semantic complexity: The acquisition of possessor inflection in Northern East Cree
Authors: Henke Ryan E. 
Published: October 2024

Abstract
This paper engages longstanding questions regarding how children acquire morphology in polysynthetic languages. It examines the roles of frequency, perceptual salience, and semantic complexity for morphemes in the acquisition of Northern East Cree possessive inflection, where prefixes and suffixes interact to encode possessors. Two studies analyze naturalistic video recordings of one adult and two children. Study 1 describes the frequency, salience, and complexity of possessor-encoding morphemes in the input. Study 2 traces the acquisition of these morphemes in child speech. Results indicate the acquisition of possessor inflection involves a combination of factors whose influences shift over time. Perceptual salience plays a key role in early noun production, but frequency later corresponds more clearly to acquisitional order for high-frequency morphemes. Complexity is hard to isolate from frequency, although neither factor clearly determines acquisitional order for low-frequency morphemes. The paper concludes by considering implications for science and potential applications for Cree communities.

AbstractSynaptic phenotypes in living patients with psychiatric disorders are poorly characterized. Excitatory glutamate α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor (AMPAR) is a fundamental component for neurotransmission. We recently developed a positron emission tomography (PET) tracer for AMPAR, [11C]K-2, the first technology to visualize and quantify AMPARs density in living human brain. In this study, we characterized patients with major psychiatric disorders with [11C]K-2. One hundred forty-nine patients with psychiatric disorders (schizophrenia, n = 42; bipolar disorder, n = 37; depression, n = 35; and autism spectrum disorder, n = 35) and 70 healthy participants underwent a PET scan with [11C]K-2 for measurement of AMPAR density. We detected brain regions that showed correlation between AMPAR density and symptomatology scores in each of four disorders. We also found brain areas with significant differences in AMPAR density between patients with each psychiatric disorder and healthy participants. Some of these areas were observed across diseases, indicating that these are commonly affected areas throughout psychiatric disorders. Schizophrenia, bipolar disorder, depression, and autism spectrum disorder are uniquely characterized by AMPAR distribution patterns. Our approach to psychiatric disorders using [11C]K-2 can elucidate the biological mechanisms across diseases and pave the way to develop novel diagnostics and therapeutics based on the synapse physiology.

Authors: Mitev Kaloyan , Frewin Kelsey L. , Augustinova Maria , Niedenthal Paula M. , Rychlowska Magdalena , Vanderwert Ross E. 
Published: October 2024

Abstract
Background
Social and familial consequences of pacifier use remain poorly understood. The present study attempts to shed more light on the characteristics of parents using pacifiers with their infants and to explore how pacifier use affects perceptions of infant emotionality, maternal stress, and parental efficacy.

Methods
The study sample consisted of 428 mothers (range: 17–49 years) of infants (0–36 months) who completed a comprehensive questionnaire assessing infant and parent characteristics as well as parenting practices and pacifier use. We compared attitudes toward pacifiers, parenting stress, children’s levels of reactivity and self-regulation, and maternal efficacy among Pacifier Users, Never-Users, and families that Tried-Pacifiers.

Results
The reported results reveal benefits of pacifier use for the family relationships, namely reduced parenting stress (p = 0.018), better parent-child dynamics (p < 0.001), and more positive perceptions of child’s affectivity (p = 0.006), which are all important aspects of infant development.

Conclusion
Our findings highlight developmental benefits of pacifier use, a practice that is known to have both positive and negative long-term consequences for healthy child development. It is, therefore, important for health professionals to have discussions about the pros and cons of pacifier use with parents.

Impact

The study provides novel insights into how and why mothers use pacifiers and into the psychological consequences of this practice.

We found pacifier use is associated with less maternal stress, better mother-child dynamics, and more positive perceptions of child’s affectivity.

Our findings document developmental benefits of pacifier use adding a new perspective to the debate on pacifiers.

Doctors, health visitors, pediatric nurses, and midwives may consider this evidence when advising parents on pacifier use.

AbstractThis study aimed to evaluate a 3-day transparent film dressing protocol after hypospadias repair. A retrospective observational study was conducted in boys with hypospadias who were operated in our institution between 2022 and 2023. Postoperatively, the penis was wrapped with a transparent film dressing, which was removed after 3 days. Postoperative complications were observed until postoperative day 14. The associations of age, meatal location, and type of procedure were analyzed using Chi square, Fisher exact, Mann Whitney, and Kruskall Wallis test (p < 0.05 = significant). Sixty-five patients were studied. Median age was five years, the majority had proximal meatus (58.5%), and underwent urethroplasty (76.9%). After dressing removal, positive bacterial culture was found in 43.1%, mild penile edema in 33.8%, bleeding in 10.8%, and SSI in 49.2% of cases, with pus formation (10.8%), dehiscence (9.2%), and urethrocutaneous fistula (10% after urethroplasty procedure). Surgical site infection and positive culture were significantly higher in patients with proximal meatus compared to distal (p = 0.031, p = 0.019; respectively). A 3-day transparent film dressing prevented penile edema and bleeding in most cases. However, the rate of SSI and positive wound culture was high, and was associated with proximal meatal location.
Generation of patterns and higher harmonics in 1D quantum droplets in tilted and driven quasi-periodic confinements

Published: October 2024

AbstractThe generation of patterns by breaking the spatial symmetry in external confinement is a captivating area of physics. The emergence of patterns is a fundamental inquiry spanning various disciplines such as nonlinear optics, condensed matter physics, and fluid dynamics. The article investigates the generation of a variety of patterns in a one-dimensional binary mixture of Bose–Einstein condensate forming quantum droplets. By solving the extended Gross–Pitaevskii equation in the presence of tilted and driven engineered bi-chromatic optical lattices (BOL), the out-of-equilibrium dynamics of droplets under strong dc and ac fields are illustrated. Under the influence of a dc field, a stripe-like pattern emerges in the temporal domain, while the scenario with ac fields demonstrates temporal periodic and bi-periodic oscillations of density waves. The width and period of formed patterns are directly correlated with the strength of ac and dc fields. Moreover, temporal modulation of the BOL potential depth yields various harmonics in the oscillations of the condensate density pattern. Through Fast Fourier Transform (FFT) analysis, it is confirmed that these harmonics encompass multiple and combinational frequencies, suggesting potential applications in generating desired frequency combs within quantum droplets. We have also carried out a thorough numerical stability check of the obtained solutions and found them sufficiently stable.
