description: We consider quantum mechanical corrections to a homogeneous, isotropic and spatially flat geometry whose scale factor expands classically as a general power of the co-moving time. The effects of both gravitons and the scalar inflaton are computed at one loop using the manifestly causal formalism of Schwinger with the Feynman rules recently developed by Iliopoulos {\it et al.} We find no significant effect, in marked contrast with the result obtained by Mukhanov {\it et al.} for chaotic inflation based on a quadratic potential. By applying the canonical technique of Mukhanov {\it et al.} to the exponential potentials of power law inflation, we show that the two methods produce the same results, within the approximations employed, for these backgrounds. We therefore conclude that the shape of the inflaton potential can have an enormous impact on the one loop back-reaction.

description: Double-negative acoustic metamaterials (AMMs) offer the promising ability of superlensing for applications in ultrasonography, biomedical sensing and nondestructive evaluation. Here, under the simultaneous increasing or non-increasing mechanisms, we develop a unified topology optimization framework considering the different microstructure symmetries, minimal structural feature sizes and dispersion extents of effective parameters. Then we apply the optimization framework to furnish the heuristic resonance-cavity-based and space-coiling metamaterials with broadband double negativity. Meanwhile, we demonstrate the essences of double negativity derived from the novel artificial multipolar LC and Mie resonances which can be induced by controlling mechanisms in optimization. Furthermore, abundant numerical simulations validate the double negativity, negative refraction, enhancements of evanescent waves and subwavelengh imaging for the optimized AMMs. Finally, we experimentally show the desired broadband subwavelengh imaging using the 3D-printed optimized space-coiling metamaterial. The present methodology and broadband metamaterials provide the ideal strategy of constructing AMMs for subwavelengh imaging technology.

description: Retinitis pigmentosa (RP) associated with biallelic variants in CDHR1 has rarely been reported, and detailed phenotyping data are not available. RP implies relative preservation of foveal cones, when compared to cone-rod dystrophy associated with biallelic null variants in CDHR1. We hypothesize that RP may occur in association with one or more hypomorphic CDHR1 alleles. Retrospective report of a 48-year-old patient with CDHR1-associated RP with a hypomorphic missense variant c.562 G>A, p. (Gly188Ser) and a novel, unreported variant affecting a canonical splice acceptor site (c.784–1 G>C). Clinical examination, multimodal retinal imaging, electroretinography, visual field testing, and mesopic microperimetry were undertaken 8 years apart. Scotopic microperimetry was also performed. The DNA sequence context of the variants was examined to identify theoretical CRISPR-Cas9 base-editing strategies. The patient presented at 35 years with a 12-year history of nyctalopia. His best corrected visual acuity was 20/20. Clinical presentation, multimodal retinal imaging studies, electroretinography, and mesopic microperimetry were typical of a progressive rod-cone dystrophy (i.e. classic RP). There were no scotomas within the central field as would be expected at this age in CDHR1-associated cone-rod dystrophy. Scotopic microperimetry suggested some preservation of macular cone over rod function, although both were severely impaired. A suitable CRISPR adenine base editor was identified that could theoretically correct the missense variant c.562 G>A, p. (Gly188Ser). CDHR1-associated RP shows a relative preservation of cone function in the presence of a presumed hypomorphic allele and may be considered a hypomorphic disease phenotype. Further work is required to identify modifying factors that determine disease phenotype since macular dystrophy, with relative sparing of rods, may also occur with hypomorphic CDHR1 alleles

description: Four new liquid crystal cyclic carbonate monomers M1–M4, with cholesteryl moiety and flexible spacer of different lengths, were synthesised through coupling reaction. The chemical structures, mesophase properties and thermal behaviour of the monomers were characterised with Fourier transform infrared spectroscopy, proton nuclear magnetic resonance spectroscopy (1H NMR), polarising optical microscopy, differential scanning calorimetry and X-ray diffraction. Based on these results, the relationship between the number of methylene groups into flexible chain and the mesomorphism of the monomers was investigated. It was found that all the monomers showed a focal conic texture of a smectic A phase and exhibited an interdigitated molecular arrangement. Moreover, the glass transition temperature and the isotropisation temperature of the monomers except M1 decreased, and the mesophase range narrowed as the number of methylene units into the flexible chain increased.

description: The compression of SH$_2$ and its subsequent decomposition to SH$_3$, presumably in a cubic Im$\overline{3}$m structure, has lead to the discovery of conventional superconductivity with the highest measured and confirmed $T_c$ to date, 203 K at 160 GPa. Recent theoretical studies suggest that a mixture of S with other elements of the chalcogen group could improve the superconducting temperature. Here, we present a detailed analysis of the thermodynamic properties of S and Se mixtures in the bcc lattice with Im$\overline{3}$m symmetry using a cluster expansion technique to explore the phase diagram of S$_x$Se$_{1-x}$H$_{3}$. In contrast to earlier reports, we find that S$_{0.5}$Se$_{0.5}$H$_3$ is not stable in the pressure range between 150-200 GPa. However, phases at compositions S$_{0.2}$Se$_{0.8}$H$_3$, S$_{0.\overline{3}}$Se$_{0.\overline{6}}$H$_3$, and S$_{0.6}$Se$_{0.4}$H$_3$ are stable at 200 GPa, while additional phases at S$_{0.25}$Se$_{0.75}$H$_3$ and S$_{0.75}$Se$_{0.25}$H$_3$ are accessible at lower pressures. Electron-phonon calculations show that the values of $T_c$ are consistently lower for all ternary phases, indicating that mixtures of S and Se with H might not be a viable route towards compounds with improved superconducting properties.

description: The public sector in Nigeria is in most quarters seen to connote inefficiency, fraudulence and public officers are seen to neglect laid down procedures in the day-to- day discharge of government business. Budget estimates were not too different from mere paper work as the contents were never religiously implemented. This scenario painted a picture of outright mismanagement of government resources by civil servants and public office holders. It is expected that the public sector should be prudent in the management of the economic resources of .the nation. The researched adopted a literature review approach in the study. The paper sees Due Process Mechanism as the harbinger of economic management and empowerment which will constitute the threshold to propel the actualization of the tripartite cardinal agenda or mission statement of the National Economic Empowerment and Development Strategy (NEEDS) of wealth creation, job creation and poverty reduction. The paper recommends that due process should remain as part of government mechanism against corruption and that the agency should remain in the Presidency.

description: The non-Abelian braiding of Majorana fermions is one of the most promising operations providing a key building block for the realization of topological quantum computation. Recently, the chiral Majorana fermions were observed in a hybrid junction btween a quantum anomalous Hall insulator and an s-wave superconductor. Here we show that if a quantum dot or Majorana zero mode couples to the chiral Majorana fermions, the resulting resonant exchange of chiral Majorana fermions can lead to the non-Abelian braiding. Remarkably, any operation in the braid group can be achieved by this scheme. We further propose electrical transport experiments to observe the braiding of four chiral Majorana fermions and demonstrate the non-Abelian braiding statistics in four-terminal devices of the hybrid junctions. Both a conductance peak due to the braiding and the braiding-order dependent conductance are predicted. These findings pave a way to perform any braiding operation of chiral Majorana fermions by electrically controllable quantum dots.

description: Abstract

The media plays a crucial role in peacebuilding, influencing public perceptions, facilitating dialogue, and shaping narratives that impact conflict resolution. This study examines the role of media in peacebuilding in Baidoa, Somalia, focusing on how local and international media contribute to conflict transformation, social cohesion, and reconciliation efforts. The research assesses the effectiveness of media in promoting peace, the challenges faced by journalists, and the potential risks of media manipulation in conflict situations.

Using a mixed-methods approach, data was collected through surveys and interviews with media professionals, policymakers, and community leaders. The findings indicate that while media can serve as a platform for promoting peace and countering misinformation, challenges such as biased reporting, political influence, security threats to journalists, and limited resources hinder its effectiveness. Additionally, media outlets that are not conflict-sensitive may exacerbate tensions by reinforcing divisions and spreading misinformation.

The study underscores the need for ethical journalism, media literacy programs, and stronger legal protections for journalists to enhance the role of media in peacebuilding. Recommendations include the promotion of conflict-sensitive reporting, increased investment in independent media, and the implementation of regulatory frameworks that ensure media independence. These insights provide valuable guidance for policymakers, media organizations, and peacebuilding practitioners working to harness the media’s potential for sustainable peace in Somalia.

We restrict these fronts to large finite intervals in the comoving frame of reference and require their centers be insensitive to the locations of the ends of the finite intervals, exhibiting thus effectively an approximate translation invariance. Only one monotonic front has this behavior and its velocity is the one that is physically selected. We present analytic results in the case of piecewise parabolic potentials, and numerical results in other cases.

description: Objective: To develop a fetal sex determination method based on maternal plasma sequencing (MPS), assess its performance and potential use in X-linked disorder counseling. Methods: 900 cases of MPS data from a previous study were reviewed, in which 100 and 800 cases were used as training and validation set, respectively. The percentage of uniquely mapped sequencing reads on Y chromosome was calculated and used to classify male and female cases. Eight pregnant women who are carriers of Duchenne muscular dystrophy (DMD) mutations were recruited, whose plasma were subjected to multiplex sequencing and fetal sex determination analysis. Results: In the training set, a sensitivity of 96% and false positive rate of 0% for male cases detection were reached in our method. The blinded validation results showed 421 in 423 male cases and 374 in 377 female cases were successfully identified, revealing sensitivity and specificity of 99.53% and 99.20% for fetal sex determination, at as early as 12 gestational weeks. Fetal sex for all eight DMD genetic counseling cases were correctly identified, which were confirmed by amniocentesis. Conclusions: Based on MPS, high accuracy of non-invasive fetal sex determination can be achieved. This method can potentially be used for prenatal genetic counseling.

Subjects: The impact of youth

peace and conflict in Somalia

description: ABSTRACT

Background: Youth unemployment in Somalia significantly impacts the country's stability and peace. High unemployment rates among young people contribute to economic marginalization and frustration, making them more susceptible to recruitment by extremist groups and involvement in criminal activities. This exacerbates existing social tensions and undermines efforts toward peacebuilding and conflict resolution. Furthermore, the lack of job opportunities hinders economic development, creating a cycle of poverty and instability. Addressing youth unemployment through education, vocational training, and job creation is crucial for fostering long-term peace and stability in Somalia.

Objective: The general objective of the study on the impact of youth unemployment on peace and conflict in Somalia is to examine the relationship between youth unemployment and its influence on the overall stability, peace, and potential for conflict within the country.

Methods: The study employed a cross-sectional descriptive research design using quantitative methods to examine the impact of youth unemployment on peace and conflict in Somalia. The sample size included 73 respondents from the target population, determined using Sloven’s formula.The researcher used a random sampling method. The data collection instrument consisted solely of closed-ended questions with predefined response options. Data analysis was conducted using the Statistical Package for the Social Sciences (SPSS v.20).

Results: The demographic analysis reveals that a significant majority of respondents, primarily aged between 25-35 years, with 61.6% holding university degrees and a majority possessing specialized skills (75.3%) and participating in training programs (67.1%), a substantial 21.9% remainunemployed. Respondents overwhelmingly perceive youth unemployment as a catalyst for social unrest and violence, with 78.1% acknowledging this connection. Alarmingly, 64.4% have directlywitnessed or experienced violence linked to youth unemployment, underscoring the urgent need for intervention. The study highlights widespread support (79.5%) for addressing youth unemployment as a pathway to enhancing peace and stability in Somalia.

Recommendations: Enhance educational and vocational training programs to better align the skills of youth with the demands of the job market. Increase investment in job creation programs by both the government and private sector. Implement and strengthen policies that support entrepreneurship among youth. Address barriers to employment identified in the study, including discrimination in the job market and inadequate government policies.

description: Quantitative structure–property relationship (QSPR) modelling has been used in many scientific fields. This approach has been extensively applied in environmental research to predict physicochemical properties of compounds with potential environmental impact. The soil sorption coefficient is an important parameter for the evaluation of environmental risks, and it helps to determine the final fate of substances in the environment. In the last few years, different QSPR models have been developed for the determination of the sorption coefficient. In this study, several QSPR models were generated and evaluated for the prediction of log Koc from the relationship with log P. These models were obtained from an extensive and diverse training set (n = 639) and from subsets of this initial set (i.e. halves, fourths and eighths). The aim of this study was to investigate whether the size of the training set affects the statistical quality of the obtained models. Furthermore, statistical equivalence was verified between the models obtained from smaller sets and the model obtained from the total training set. The results confirmed the equivalence between the models, thus indicating the possibility of using smaller training sets without compromising the statistical quality and predictive capability, as long as most chemical classes in the test set are represented in the training set.

description: Indirubin is the main component of the traditional Chinese medicine Indigo naturalis (IN), a potent agonist of aryl hydrocarbon receptors (AhRs). In China, IN is used to treat psoriasis and ulcerative colitis, and indirubin is used for the treatment of chronic myelogenous leukaemia. However, IN and indirubin have adverse reactions, such as abdominal pain, diarrhoea, and intussusception, and their specific mechanism is unclear.The purpose of our research was to determine the specific mechanism underlying the adverse effects of IN and indirubin. By tracking the modifications in guinea pigs after the intragastric administration of indirubin for 28 days.The results demonstrate that indirubin could accelerate bowel movements and decrease intestinal acetylcholinesterase (AchE) expression. Experiments with NCM460 cells revealed that indirubin significantly reduced the expression of AchE, and the AchE levels were increased after the silencing of AhR and re-exposure to indirubin.This study showed that the inhibition of AchE expression by indirubin plays a key role in the occurrence of adverse reactions to indirubin and that the underlying mechanism is related to AhR-mediated AchE downregulation.

Resonance zones in action space

description: The classical and quantum mechanics of isolated, nonlinear resonances in integrable systems with N>=2 degrees of freedom is discussed in terms of geometry in the space of action variables. Energy surfaces and frequencies are calculated and graphically presented for invariant tori inside and outside the resonance zone. The quantum mechanical eigenvalues, computed in the semiclassical WKB approximation, show a regular pattern when transformed into the action space of the associated symmetry reduced system: eigenvalues inside the resonance zone are arranged on N-dimensional cubic lattices, whereas those outside are, in general, non-periodically distributed. However, N-dimensional triclinic (skewed) lattices exist locally. Both kinds of lattices are joined smoothly across the classical separatrix surface. The statements are illustrated with the help of two and three coupled rotors.

This procedure provided a wide range of valuable, structurally diverse 3-alkyl-imidazopyridine and 4-alkyl-1-naphthylamine derivatives in moderate-to-good yields and with good functional group tolerance.
The Educational Paradaox: Qatari Women Educated Yet Unemployed

description: This research focuses on a paradox: Qatari women are highly educated yet unemployed or underemployed in greater numbers. Though the emphasis is on women, this interview-based research also includes men’s perspectives on the matter. This paper tackles this paradox through an analysis of patriarchal structures, state, education, and culture. It asks how ten (10) Qatari youth view, understand, and experience Qatari women’s empowerment. Though women are being incorporated more in all fields of work, the culture and society still hinders them in terms of the normative culture it perpetuates and sustains. In addition, this paper presents findings from an online survey that was made available to the public both in English and Arabic. Through this mixed methodology, it was concluded that culture plays a pivotal role in Qatari women’s advancement. Women can only be widely employed in Qatar with the full support of both their private family and the public state. Though the unique economy in Qatar essentially allows women to stay at home –something almost impossible to envision anywhere else in the world including the West, where women’s salaries are essential. The literature is missing an understanding of how the internalization of patriarchy occurs, however, and how a conservative culture and society serve as the mobilizing factor to such a mentality. Finally, it is hoped that this preliminary investigation into the matter serves as a springboard for forthcoming studies on the generational difference and how it plays in socializing women for public mobility or restricting their access.

description: Unmanned aerial vehicles (UAVs) are a relatively new technology. Their application can often involve complex and unseen problems. For instance, they can work in a cooperative-based environment under the supervision of a ground station to speed up critical decision-making processes. However, the amount of information exchanged among the aircraft and ground station is limited by high distances, low bandwidth size, restricted processing capability, and energy constraints. These drawbacks restrain large-scale operations such as large area inspections. New distributed state-of-the-art processing architectures, such as fog computing, can improve latency, scalability, and efficiency to meet time constraints via data acquisition, processing, and storage at different levels. Under these amendments, this research work proposes a mathematical model to analyze distribution-based UAVs topologies and a fog-cloud computing framework for large-scale mission and search operations. The tests have successfully predicted latency and other operational constraints, allowing the analysis of fog-computing advantages over traditional cloud-computing architectures.

O(d,d)-invariance in inhomogeneous string cosmologies with perfect fluid

Year: 1998
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In the first part of the present paper, we show that O(d,d)-invariance usually known in a homogeneous cosmological background written in terms of proper time can be extended to backgrounds depending on one or several coordinates (which may be any space-like or time-like coordinate(s)). In all cases, the presence of a perfect fluid is taken into account and the equivalent duality transformation in Einstein frame is explicitly given. In the second part, we present several concrete applications to some four-dimensional metrics, including inhomogeneous ones, which illustrate the different duality transformations discussed in the first part. Note that most of the dual solutions given here do not seem to be known in the literature.

description: Solution is presented to the simplest problem about the vacuum backreaction on a pair creating source. The backreaction effect is nonanalytic in the coupling constant and restores completely the energy conservation law. The vacuum changes the kinematics of motion like relativity theory does and imposes a new upper bound on the velocity of the source.
