description: The value of the Prandtl number $P$ exerts a strong influence on convection-driven dynamos in rotating spherical shells filled with electrically conducting fluids. Low Prandtl numbers promote dynamo action through the shear provided by differential rotation, while the generation of magnetic fields is more difficult to sustain in high-Prandtl-number fluids where higher values of the magnetic Prandtl number $P_m$ are required. The magnetostrophic approximation often used in dynamo theory appears to be valid only for relatively high values of $P$ and $P_m$. Dynamos with a minimum value of $P_m$ seem to be most readily realizable in the presence of convection columns at moderately low values of $P$. The structure of the magnetic field varies strongly with $P$ in that dynamos with a strong axial dipole field are found for high values of $P$ while the energy of this component is exceeded by that of the axisymmetric toroidal field and by that of the non-axisymmetric components at low values of $P$. Some conclusions are discussed in relation to the problem of the generation of planetary magnetic fields by motions in their electrically conducting liquid cores.

description: Existence of a photon circular orbit can tell us a lot about the nature of the underlying spacetime, since it plays a pivotal role in the understanding of the characteristic signatures of compact objects, namely the quasi-normal modes and shadow radius. For this purpose, determination of the location of the photon circular orbit is of utmost importance. In this work, we derive bounds on the location of the photon circular orbit around compact objects within the purview of general relativity and beyond. As we have explicitly demonstrated, contrary to the earlier results in the context of general relativity, the bound on the location of the photon circular orbit is not necessarily an upper bound, rather depending on the matter content it is possible to arrive at a lower bound as well. This have interesting implications for the quasi-normal modes and shadow radius, the two key observables related to the strong field tests of gravity. Besides discussing the bound for higher dimensional general relativity, we have also considered how the bound on the photon circular orbits gets modified in the braneworld scenario, for pure Lovelock and general Lovelock theories of gravity. Implications of these results for compact objects have also been discussed.

description: We first briefly present a consistent world-volume Lagrangian description of lightlike p-branes (LL-branes) in two equivalent forms - a Polyakov-type and a dual to it Nambu-Goto-type formulations. The most important characteristic features of LL-brane dynamics are: (i) the brane tension appears as a non-trivial additional dynamical degree of freedom; (ii) consistency of LL-brane dynamics in a spherically or axially symmetric gravitational background of codimension one requires the presence of an event horizon which is automatically occupied by the LL-brane ("horizon straddling"). Next we consider a bulk Einstein-Maxwell system interacting self-consistently with a codimension one LL-brane. We find spherically symmetric traversable wormhole solutions of Misner-Wheeler type produced by the LL-brane sitting at the wormhole throat with wormhole parameters being functions of the dynamical LL-brane tension.

description: Measurements of the deflection induced by thermal noise have been performed on a rectangular atomic force microscope cantilever in air. The detection method, based on polarization interferometry, can achieve a resolution of 1E-14 m/rtHz in the frequency range 1 kHz ? 800 kHz. The focused beam from the interferometer probes the cantilever at different positions along its length and the spatial modes' shapes are determined up to the fourth resonance, without external excitation. Results are in good agreement with theoretically expected behavior. From this analysis accurate determination of the elastic constant of the cantilever is also achieved.

description: Abstract

Background:  Globally, one of the main causes of chronic morbidity and mortality is chronic obstructive pulmonary disease. A clinical pathway is an evidence-based interdisciplinary management tool that defines and optimizes the many tasks performed by professionals involved in patient care, improving patient outcomes and elevating staff and patient satisfaction. Aim: Determine the effect of implementing clinical pathway on level of dyspnea and anxiety among elderly patients with chronic obstructive pulmonary disease. Research design: A quasi experimental research design was utilized. Method: Sixty two COPD elderly patients who were attending the Mansoura University Hospital's chest medicine department were included in the purposeful sample. The individuals were split equally into two groups: study group (n=31) who received clinical pathway protocol, and control group (n=31) who received only routine care. Results: Patients in the study group had significantly improved perceived level of dyspnea on discharge than the control group with mean 4.22±1.05 and 6.00±1.36 for the study group and control group respectively. Also, patients in the study group had significantly improved level of anxiety on discharge than the control group with mean 11.38±3.83 and 18.48±5.98 for the study group and control group respectively. Conclusion: Clinical pathway is effective tool in improving chronic obstructive pulmonary disease patients' level of perceived anxiety and dyspnea. Recommendation: Training programs should be implemented for nurses about respiratory care based on the clinical pathway to improve nurses' performance and patients' outcomes.

description: Hole doped transition metal oxides are famous due to their extraordinary charge transport properties, such as high temperature superconductivity (cuprates) and colossal magnetoresistance (manganites). Astonishing, the mother system of these compounds is a Mott insulator, whereas important role in the establishment of the metallic or superconducting state is played by the way that holes are self-organized with doping. Experiments have shown that by adding holes the insulating phase breaks into antiferromagnetic (AFM) regions, which are separated by hole rich clumps (stripes) with a rapid change of the phase of the background spins and orbitals. However, recent experiments in overdoped manganites of the La(1-x)Ca(x)MnO(3) (LCMO) family have shown that instead of charge stripes, charge in these systems is organized in a uniform charge density wave (CDW). Besides, recent theoretical works predicted that the ground state is inhomogeneously modulated by orbital and charge solitons, i.e. narrow regions carrying charge (+/-)e/2, where the orbital arrangement varies very rapidly. So far, this has been only a theoretical prediction. Here, by using 139La Nuclear Magnetic Resonance (NMR) we provide direct evidence that the ground state of overdoped LCMO is indeed solitonic. By lowering temperature the narrow NMR spectra observed in the AFM phase are shown to wipe out, while for T<30K a very broad spectrum reappears, characteristic of an incommensurate (IC) charge and spin modulation. Remarkably, by further decreasing temperature, a relatively narrow feature emerges from the broad IC NMR signal, manifesting the formation of a solitonic modulation as T->0.

description: MYC is an essential transcription factor responsible for the regulation of expression of genes involved in proliferation, cell growth and a variety of metabolic pathways. Its activity regulates ribosomebiogenesis and protein synthesis. Normal cells have mechanisms to control MYC activity, while in cancer cells, these mechanisms are often disrupted. On the molecular level, increased MYC expressioncauses proteotoxic stress and an increased need to maintain proteostasis. In the clinic, increased MYC expression occurs in various cancer types and is associated with a more aggressive phenotype and aworse disease prognosis. MYC can trigger the unfolded protein response and plays important role in regulation of HSF1. Under proteotoxic conditions, HSF1 act as a regulator of heat shock protein (HSP)genes (Hsp90, Hsp70, Hsp40 etc.) essential for native protein conformation maintenance and removal of denatured protein by proteasome. Hsp90 and its co-chaperones have emerged as effective targetsfor anticancer therapy. The presented study seeks to explore how heightened MYC activity influences proteostasis and the responsiveness of tumor cells to anticancer agents targeting Hsp90 orproteasome.

We give a de Sitter solution for the four-dimensional cosmology as a good approximation to the early universe inflation. We show that the graviton has a localizable massless mode, and a series of continuous massive modes, separated by a mass gap. There could be a normalizable massive mode, depending on the background solution. The gravitational waves of massless mode evolve the same as the four dimensional theory, while that of the massive modes evolve greatly different from the massless mode.

description: Two dimensional materials are important for electronics applications. A natural way for electronic structure engineering on two dimensional systems is on-plane chemical functionalization. Based on density functional theory, we study the electronic structures of fluorine substituted planar polysilane and graphane. We find that carbon and silicon present very different surface chemistry. The indirect energy gap of planar polysilane turns to be direct upon fluorine decoration, and the gap width is mainly determined by fluorine coverage regardless of its distribution on the surface. However, electronic structure of fluorine doped graphane is very sensitive to the doping configuration, due to the competition between antibonding states and nearly-free-electron (NFE) states. With specific fluorine distribution pattern, zero-dimensional and one-dimensional NFE states can be obtained. We have also studied the chemical modification with -OH or -NH$_2$ group. Carbon seems to be too small to accommodate big functional groups on its graphane skeleton with a high concentration.

description: Abstract

This paper examines the integration of smart technologies across major global ports, focusing on their impact on operational efficiency, security, and environmental sustainability. Utilizing a comparative case study approach, the study analyzes the implementation and outcomes of innovative technologies such as the Internet of Things (IoT), Artificial Intelligence (AI), blockchain, and big data analytics in ports like Singapore, Rotterdam, and Los Angeles. Key findings demonstrate that smart technologies significantly enhance port operations by streamlining cargo handling, improving asset utilization, and reducing environmental impacts through efficient energy management and emissions monitoring. The study also explores the broad implications for global trade, highlighting how technological advancements contribute to increased supply chain efficiency and resilience. Despite the positive outcomes, the research identifies challenges including high implementation costs, cybersecurity risks, and the need for extensive workforce training. Recommendations emphasize the need for strategic investments, robust policy frameworks, and international collaboration to overcome these barriers. The findings contribute valuable insights into the transformative potential of smart technologies in maritime logistics and offer guidance for policymakers, port authorities, and industry stakeholders aiming to optimize modern port operations and meet the demands of global trade and environmental stewardship.

description: We present new high resolution spectroscopy of the low mass X-ray binary Cyg X-2 which enables us to refine the orbital solution and rotational broadening of the donor star. In contrast with Elebert et al (2009) we find a good agreement with results reported in Casares et al. (1998). We measure $P=9.84450\pm0.00019$ day, $K_2=86.5\pm1.2$ km s$^{-1}$ and $V \sin i=33.7\pm0.9$ km s$^{-1}$. These values imply $q=M_{2}/M_{1}=0.34 \pm 0.02$ and $M_{1}=1.71\pm 0.21$ M$_{\odot}$ (for $i=62.5 \pm 4^{\circ}$). Therefore, the neutron star in Cyg X-2 can be more massive than canonical. We also find no evidence for irradiation effects in our radial velocity curve which could explain the discrepancy between Elebert et al's and our $K_2$ values.

description: In this paper, we report white dwarfs identified in the 5th Data Release of the Large Area Multi-Object fibre Spectroscopic Telescope, including spectral types of DA, DB, DC, DZ, and so on. There are 2 625 DA spectra of 2 281 DA stars, 182 DB spectra of 166 DB stars, 62 DC spectra of 58 DC stars, 36 DZ spectra of 33 DZ stars and many other types identified, in addition to our previous paper (Data Release 2). Among those sources, 393 DA stars and 46 DB stars are new identifications after cross-matching with the literature. In order to select DA candidates, we use the classification result from the LAMOST pipeline, colour-colour cut method and a random forest machine learning method. For DBs, since there is no template for DB in the pipeline model, a random forest machine learning method is chosen to select candidates. All the WD candidates have been visually checked individually. The parameters of effective temperature, surface gravity, mass, and cooling age have been estimated for relatively high signal-to-noise ratio DAs and DBs. The peaks of the DA and DB mass distributions are found to be around 0.62Msun and 0.65Msun, respectively. Finally, the data and method we used to select white dwarf candidates for the second phase of LAMOST survey are also addressed in this paper.

We show that the de Rham class of the Lee form can be naturally identified with the homomorphism projecting Γto its dilation factors, thus completing the description of locally conformal Kaehler geometry in this equivariant setting. The rank r of a locally conformal Kaehler manifold is the rank of the image of this homomorphism. Using algebraic number theory, we show that r is non-trivial, providing explicit examples of locally conformal Kaehler manifolds with 1

description: The expression of phospholipase C-β1 (PLC-β1) and cyclin D3 is highly induced during skeletal
myoblast differentiation. We have previously shown that PLC-β1 activates cyclin D3 promoter during
the differentiation of myoblasts to myotubes, indicating that PLC-β1 is a crucial regulator of mouse
cyclin D3 gene. Here we report that PLC-β1 catalytic activity plays a role in the increase of cyclin D3
levels and in the induction of differentiation of C2C12 skeletal muscle cells. PLC-β1 mutational
analysis revealed the importance of His331 and His378 for the catalytic activity. We show that following
insulin administration, cyclin D3 mRNA levels are lower in cells overexpressing the PLC-β1
catalytically inactive form, as compared to wild type cells. We describe a novel signaling pathway
elicited by PLC-β1 that modulates Activator Protein-1 (AP-1) activity. Indeed, gel mobility shift assays
indicate that there is a c-jun binding site located in cyclin D3 promoter region specifically regulated by
PLC-β1 and that c-jun binding activity is significantly increased by insulin stimulation and PLC-β1
overexpression. Moreover, mutation of c-jun/AP-1 binding site decreases the basal cyclin D3 promoter
activity and eliminates its induction by insulin and PLC-β1 overexpression. Interestingly, we observed
that the ectopic expression of the Inositol Polyphosphate Multikinase (IPMK) in C2C12 myoblasts
enhances cyclin D3 gene expression and that the mutation of c-jun site in cyclin D3 promoter
determines an impairment of IPMK-dependent promoter induction. These results indicate that PLC-β1
activates a c-jun/AP-1 target gene, i.e. cyclin D3, during myogenic differentiation through IPMK
signaling.

description: Crystals of the molecular magnet Mn12-acetate are known to contain a small fraction of low- symmetry (minor) species with a small anisotropy barrier against spin reversal. The lower barrier leads to faster magnetic relaxation and lower coercive field. We exploit the low coercive fields of the minor species to make a direct determination of the dipole field in Mn12-ac. We find that the dipolar field of a fully magnetized crystal is 51.5 \pm 8.5 mT, consistent with theoretical expectations.

A comparative study of central cardiovascular dynamics in vertebrates
Creators: name: Langille, Brian Lowell
Publisher: name: University of British Columbia
Year: 2010

description: The dynamic properties of blood flow through the heart and arterial systems have been examined in representative species of fish, amphibia, birds and mammals. In the amphibian examined, the bullfrog Rana catesbeiana. the conus arteriosis was found to perform no active valving function and hence was not responsible for shunting blood to, or away from, the lungs in response to lung ventilation or apnoea. Conus volume changes generated a small fraction of cardiac stroke volume although a low impedance of the pulmocutaneous vasculature resulted in a preferential distribution of this blood to the gas exchanger circulations. The pressure pulse took a negligible fraction of the cardiac cycle to traverse the arterial tree and peripherally recorded pressures were similar in profile to central pressures, these results indicating that wave transmission effects were small. Impedance analysis of pressure and flow data suggested that a two element lumped parameter (windkessel) model accurately describes arterial pressure-flow relationships in the bullfrog. Arterial haemodynamics in the cod, Gadus morhua was examined in terms of a hydraulic model of the 'in series' gill and systemic circulations. Results indicate that the dorsal aorta is not a rigid conduit and the compliance of this vessel has a marked effect on the pulsatility of blood flow through the gills. in the duck. Anas platyrhynchos pressure and flow profiles have been mapped throughout the central circulation. Mean systemic arterial pressure (143 ± 2 mm Hg) and cardiac output (219 ± 7 ml/min per kg) were high compared with mammals of similar size although pulmonary pressures were not high, perhaps because of the unique structure of the avian lung. 75% of total systemic flow was distributed to wing, flight muscles and head by the brachiocephalic arteries. Unlike the situation in the bullfrog wave transmission phenomena had a pronounced effect on arterial pressure and flow signals and impedance data were characterised by features commonly ascribed to the effects of wave reflection. Therefore it is concluded that the windkessel is not a realistic model of the avian arterial system. Pressures generated in both ventricles of the rabbit heart were influenced by contraction of the opposite ventricle although the influence of right ventricular contraction on left ventricular pressure was negligible during normal cardiac function and only became marked when the right ventricular volumes were large or left ventricular volumes were small. Comparison of the effects of vasomotion and artificially induced discrete reflections confirmed that pulse wave transmission effects in mammalian arteries are dominated by reflections from the arteriolar beds. Although studies of a hydraulic model confirmed the viability of transmission line theories on the effects of spatial variations in arterial wall elasticity, close examination suggests that this 'elastic taper' does not have a dominant effect on wave propagation.

description: Planets with large moon(s) or those in the habitable zone of low-mass stars may experience much stronger tidal force and tide-induced ocean mixing than that on Earth. Thus, the vertical diffusivity (or, more precisely, diapycnal diffusivity) on such planets, which represents the strength of vertical mixing in the ocean, would be greater than that on Earth. In this study, we explore the effects of extremely high diffusivity on the ocean circulation and surface climate of Earth-like planets in one asynchronous rotation orbit. The response of planetary climate to 10 and 100 times greater vertical diffusivity than that found on Earth is investigated using a fully coupled atmosphere-ocean general circulation model. In order to perform a clear comparison with the climate of modern Earth, Earth's orbit, land-sea configuration, and present levels of greenhouse gases are included in the simulations. We find that a larger vertical diffusivity intensifies the meridional overturning circulation (MOC) in the ocean, which transports more heat to polar regions and melts sea ice there. Feedback associated with sea ice, clouds, and water vapor act to further amplify surface warming. When the vertical diffusivity is 10 (100) times the present-day value, the magnitude of MOC increases by $\approx$3 (18) times, and the global-mean surface temperature increases by $\approx$4$^{\circ}$C (10$^{\circ}$C). This study quantifies the climatic effect of an extremely strong vertical diffusivity and confirms an indirect link between planetary orbit, tidal mixing, ocean circulation, and surface climate. Our results suggest a moderate effect of varying vertical ocean mixing on planetary climate.

description: Abstract

Flaxseed has sparked a lot of attention as an edible and nutritional oil source due to its extraordinary protein level, high omega-3 fatty acid concentration, and potentially medicinal lignans content. One of the key components of flaxseeds is enriched oil content, which accounts more than 40% of their composition and is mainly responsible for dietary and nutritional significance. The bioavailability and health benefits of flaxseed constituents are greatly influenced by considerations such as the extraction process and the matrix in which they are contained. This article aims to review unique and advanced techniques used for extraction of flaxseed oil along with the comparison of maximum oil yield obtained from different procedures. This in-depth review, flaxseed oil is designed to highlight the correlations between the chemical composition of flaxseed oil and its potential physiological impacts with special reference towards heart, CNS, and bones. This study also represents summary of beneficial synergistic effects of flaxseed oil with other oils (olive oil & sesame oil) and medicines owing to its anti-inflammatory, antioxidant, antihypertensive and anticancer actions. This article offers the most recent and thorough investigation of lignan content of flaxseed oil and its potential health benefits for addressing a range of health problems. Additionally, efforts should be made to mitigate the presence of antinutritional factors in flaxseed oil and to develop innovative formulations and delivery systems that maximize their health benefits. Overall, flaxseed oil represents a favorable prospect for the expansion of functional foods and nutraceuticals aimed at improving human health and well-being.

description: We re-examine the recent suggestion of a high fraction of transition discs (i.e. those with a cleared inner hole) in M stars, motivated by the fact that we expect that, for M stars, even discs without inner holes should exhibit very weak excess shortward of around 10um. Our analysis of spectral energy distribution models suggest that this indeed means that M stars where a detectable excess begins at around 6um may be mis-classified as transition discs when in fact they have optically thick dust extending in to the dust sublimation radius. Consequently, we estimate that the transition disc fraction among M stars in the Coronet cluster is ~15 +/-10 % (rather than the recently claimed value of 50%). This revised figure would imply that the transition disc fraction is not after all markedly higher in later type stars. We suggest that for M stars, transition discs can only be readily identified if they have emission that is close to photospheric out to > 10um.

description: The transition metal-catalyzed allylic alkylation (Tsuji-Trost type reaction)  is a powerful tool for C-C, C-N, and C-O bond formation, which has been widely applied to organic chemistry over the last decades. 
Typical substrates for this transformation are activated allylic compounds such as halides, esters, carbonates, carbamates, phosphates, and so on. However, use of these substrates is associated with the disadvantage of generating a stoichiometric amount of chemical waste. Furthermore, these starting materials have to be prepared in an extra step from the corresponding allylic alcohol. Thus, ideal substrates would be the allylic alcohols themselves, with water being the only byproduct in this case. However, the scarse propensity of the hydroxyl moiety to act as good leaving group has significantly limited their use so far. 
During the last decade significant efforts have been made in order to develop more atom-economical and environmentally-friendly allylic alkylation protocols by employing allylic alcohols directly. 
In this PhD dissertation two main projects addressing this topic are presented. “Project 1” deals with the development of new metal-catalyzed intramolecular Friedel-Crafts (FC) allylic alkylations of electron-rich (PAPER A), as well as challenging electron-poor arenes (PAPER B) with alcohols. In “Project 2”, gold(I)-catalyzed intramolecular and stereoselective allylic alkylation reactions are reported. In particular, a FC alkylation of indole-containing allylic alcohols is presented in PAPER C. While, an O-alkylation of aminol-containing allylic alcohols is reported in PAPER D. To the best of knowledge, these reports represent the first example of gold(I)-catalyzed stereoselective alkylations with alcohols.

description: In this work we investigate a cosmological model with the tachyon and fermion fields with barotropic equation of state, where pressure $p$, energy density $ρ$ and barotropic index $γ$ are related by the relation $p=(γ-1)ρ$. We applied the tachyonozation method which allows to consider cosmological model with the fermion and the tachyon fields, driven by special potential. In this paper, tachyonization model was defined from the stability analysis and exact solution standard of the tachyon field. Analysis of the solution via statefinder parameters illustrated that our model in fiducial points with deceleration parameter $q = 0.5$ and statefinder $r = 1$ which corresponds to the matter dominated universe (SCDM) but, ends its evolution at a point in the future $(q =-1, \ r = 1)$ which corresponds to the de-Sitter expansion. Comparison of the model parameters with the cosmological observation data demonstrate, that our proposed cosmological model is stable at barotropic index $γ_0=0.00744$.

description: Abstract

This research is about the micronutrient deficiency in pre-adolescent girls in rural areas of Pakistan. Pre-adolescence and adolescence are a highly anabolic time when more of all nutrients are needed. One city, Faisalabad, was chosen out of the 100 in and surrounding Pakistan. Some specific rural areas of Faisalabad such as Chak Jhumra and Banga Chak were selected for this study. Sample of 45 pre-adolescent girls in between ages of 10-15 years were purposefully chosen for the study. The interview schedule was used to gather data on the student's demographic profile, including name, sex, and age; household income; parent's occupation; birth order; food insecurity; and the student's type of family. Additionally, anthropometric measurements, including height and weight; lifestyle behaviors, including eating habits; exercise; and physical activity, were also obtained. The frequency of nutrition issues such anemia, stunted development, and a lack of vitamin B-complex was shown by the examination of the nutritional condition of the chosen rural pre-adolescents. All the results were obtained by testing blood sample of each girl and by estimating their nutrient intakes. To put it in a nutshell, girls older than 12 years old both had inadequate intakes of micronutrients and macronutrients in these rural areas of Pakistan.

description: This report is a deliverable of the SEALIVE H2020 project. SEALIVE aims at demonstrating innovative circular strategies for bio-based plastics in land and sea applications. Within SEALIVE there is particular research on the policy implications of the production and use of bio-based plastics (BBP) and biodegradable and compostable plastics (BDCP). The research is exploring the different types of policy instruments of relevance to these materials (legal and institutional). This policy research explores both EU and international policy. This Deliverable, therefore, is a report that sets out the first results of the policy analysis. It reaches conclusions relating to the policies and their institutional context. It does not, however, make recommendations (such as that a particular policy be amended to support or limit the production or use of these materials). SEALIVE will produce such policy recommendations later in 2023 and will take account of the European Commission’s own policy developments in this area, as well as international policy developments. There are many policy interactions relevant to those issues, concerning BBP and BDCP. For many issues policy conclusions concerning these materials cannot be separated from the wider issue of plastics policy. What society wishes to do with the future of plastics (and what can be achieved) are critical to determine first and then consider how BBP/BDCP contribute, or not contribute, to this. The EU Plastics Strategy and subsequent developments on limiting single use plastics provide a guide to this. Alongside this, the wide range of different situations and context within the EU and globally need to be taken fully into account – a good policy conclusion in one place may not work somewhere else.
