description: Considering the upcoming OWFA, we use simulations of the foregrounds and the $z = 3.35$ HI 21-cm intensity mapping signal to identify the $(k_{\perp},k_{\parallel})$ modes where the expected 21-cm power spectrum $P(k_{\perp},k_{\parallel})$ is substantially larger than the predicted foreground contribution. Only these uncontaminated $k$-modes are used for measuring $P(k_{\perp},k_{\parallel})$ in the "Foreground Avoidance" technique. Though the foregrounds are largely localised within a wedge. we find that the small leakage beyond the wedge surpasses the 21-cm signal across a significant part of the $(k_{\perp},k_{\parallel})$ plane. The extent of foreground leakage is extremely sensitive to the frequency window function used to estimate $P(k_{\perp},k_{\parallel})$. It is possible to reduce the leakage by making the window function narrower, however this comes at the expense of losing a larger fraction of the 21-cm signal. It is necessary to balance these competing effects to identify an optimal window function. Considering a broad class of cosine window functions, we identify a six term window function as optimal for 21-cm power spectrum estimation with OWFA. Considering only the $k$-modes where the expected 21-cm power spectrum exceeds the predicted foregrounds by a factor of $100$ or larger, a $5\,σ$ detection of the binned power spectrum is possible in the $k$ ranges $0.18 \leq k \leq 0.3 \, {\rm Mpc}^{-1}$ and $0.18 \le k \le 0.8 \, {\rm Mpc}^{-1}$ with $1,000-2,000$ hours and $10^4$ hours of observation respectively.

description: This paper provides an overview and description of the voluntary Faculty Teaching Exchange program developed to assess whether or not a collaborative teaching exchange program might impact the culture of teaching and learning on a remote interdisciplinary satellite campus. Both full and part-time faculty members were invited to participate as Classroom Hosts and/or Classroom Observers. Data collection methods included pre and post surveys, common rubrics, reflective analyses, and focus group sessions. Both qualitative and quantitative data were collected to assess impact on the campus teaching culture. Statistical analysis was conducted to assess the effectiveness of this program and the factors within the program that were most significant in influencing participation and success of the exchange.

description: We estimate the present-day effects on rural Moroccan households of past international migration--specifically, recruitment to work in the French mines sixty years--and its associated remittances and pensions. Using cluster analysis twice—once to categorize households as poor and non-poor in the early 1960s and again to categorize the directly-descended household in 2014—we identify the households that moved upward economically over the intervening period. Seemingly-unrelated probit estimation is then used to gauge the degree to which migration facilitated this process. We find that migration significantly increased the likelihood that the sending family's current-day members would presently be non-poor. Surprisingly, we also find that the simple act of applying to migrate also has a similar effect. For the poorest (in the pre-migration period) of households, recruitment for work could well have been exogenous. For these households, migration to work in the French mines is, by far, the strongest predictor of escaping poverty sixty years later.

HealthTech: critically appraising the innovation ecosystem of a transformative technology
Creators: name: Vincent, George
Publisher: name: Loughborough University
Year: 2025

description: The last decade has seen the rapid emergence of a HealthTech innovation ecosystem seeking to transform and disrupt the health industry. Set in the context of the broader digitalisation and platformisation processes unfolding throughout the economy and society at large, the HealthTech sector is already having a significant impact on the health of individuals and the ways in which they access and receive healthcare. Yet, there remains a relative dearth of literature examining the HealthTech sector, with literature to date predominantly concerned with digital technologies and wearable devices, rather than the more fundamental dynamics of the sector itself. Building on the developing body of work exploring the emergence of other ‘-tech’ industries, this study undertakes an in-depth qualitative examination of HealthTech to uncover how firms come together with financial, governmental and health actors, and wider institutional structures in ways which drive and shape the development of new innovations and technologies. The findings demonstrate how the UK innovation- and health-focused institutional environments combine to meaningfully shape the trajectories and strategies of HealthTech firms, and their abilities to grow and access core markets. Moreover, the research shows the importance placed on, often highly specialised, network resources and social capital by HealthTech firms, and their role in enabling the negotiation of this complex institutional environment, and the development and deployment of the firms’ resources and capabilities in pursuit of innovation.

description: We study time dependence of various measures of entanglement (covariance entanglement coefficient, purity entanglement coefficient, normalized distance coefficient, entropic coefficients) between resonantly coupled modes of the electromagnetic field in ideal cavities with oscillating boundaries. Two types of cavities are considered: a three-dimensional cavity possessing eigenfrequencies $ω_3=3ω_1$, whose wall oscillates at the frequency $ω_w=2ω_1$, and a one-dimensional (Fabry--Perot) cavity with an equidistant spectrum $ω_n= nω_1$, when the distance between perfect mirrors oscillates at the frequencies $ω_1$ and $2ω_1$. The behaviour of entanglement measures in these cases turns out to be completely different, although all three coefficients demonstrate qualitatively similar time dependences in each case (except for some specific situations, where the covariance entanglement coefficient, based on traces of covariance submatrices, seems to be essentially more sensitive to entanglement than other measures, which are based on determinants of covariance submatrices). Different initial states of the field are considered: vacuum, squeezed vacuum, thermal, Fock, and even/odd coherent states.

description: A new dinuclear complex, [HgCl2L]2, was prepared using a Schiff base derived from benzimidazole (L = [1-(1H-benzo[d]imidazol-2-yl)-N-(4-methoxyphenyl)ethan-1-imine]. The mercury complex was obtained in good yield by one-pot reaction under microwave irradiation from 2-acetylbenzimidazole and p-anisidine, followed by addition of HgCl2. The Hg(II) complex has been characterized by single-crystal X-ray diffraction analysis, IR and UV-vis spectroscopy. The mercury complex is built up from a dinuclear unit related by an inversion center through two bridging chlorine atoms. Each mercury atom is coordinated by two N atoms of the Schiff base L, one terminal Cl atom and two bridging Cl atoms in a square pyramidal geometry. To support experimental data, theoretical calculations including molecular geometry, electronic transitions and vibration frequencies of the ligand and its complex in the ground state were carried out using the global hybrid (B3LYP) density functional. In addition, a qualitative description of excited states and charge transfer character of electronic transitions states were carried out by plotting the Natural Transition Orbitals (NTOs) for main states. Theoretical calculations are in good agreement with experimental values.

Complexes 2 and 3 have been structurally characterized. DNA- and protein-binding and cleavage studies revealed that 7 possesses stronger DNA- and protein-binding efficiency and also exhibits self-activating DNA-cleavage in the absence of an activating agent. The hydrophobic complexes 4 and 5 induced self-activated protein cleavage and yielded a single-cleaved fragment each. The cytotoxic property of all the seven complexes was examined by incubation with the human small cell lung carcinoma cell line A549. Complexes 4 and 6 exhibited almost similar cytotoxic properties [IC50 = 1.4 µM (4) and 1.3 µM (6)], which was 9.3 and 10 times, respectively, more efficient than cisplatin (IC50 = 13 µM). Complex 4 induced generation of the highest level of intracellular ROS which correlates with its efficient cytotoxic activity and provides scope for further investigation as a potential anticancer agent.

description: The advent of the Gaia era has led to potentially revolutionary understanding of dark matter (DM) dynamics in our galaxy, which has important consequences for direct detection (DD) experiments. In this paper, we study how the empirical DM velocity distribution inferred from Gaia-Sausage, a dominant substructure in the solar neighborhood, affects the interpretation of DD data. We survey different classes of operators in the non-relativistic effective field theory that could arise from several relativistic benchmark models and emphasize that the Gaia velocity distribution could modify both the total number of events as well as the shape of the differential recoil spectra, the two primary observables in DD experiments. Employing the euclideanized signal method, we investigate the effects of the Gaia distribution on reconstructing DM model parameters and identifying the correct DM model given a positive signal at future DD experiments. We find that for light DM with mass ~10 GeV, the Gaia distribution poses an additional challenge for characterizing DM interactions with ordinary matter, which may be addressed by combining complementary DD experiments with different targets and lowering the detection threshold. Meanwhile, for heavy DM with mass above ~30 GeV, depending on the type of DM model, there could be a (moderate) improvement in the sensitivity at future DD experiments.

description: A clear insight of the galaxies hosting active galactic nuclei is of fundamental importance for understanding the processes of galaxies and nuclei formation and their cosmic evolution. A good characterization of the host galaxies properties requires images of excellent quality in order to disentangle the light of the galaxy from that of the bright nucleus. To this aim HST has provided a major improvement of data on QSOs (Disney et al. 1995; Bahcall et al. 1996, 1997; Boyce et al. 1998; McLure et al. 1999; Hamilton et al. 2000; Kukula et al. 2001) and BL Lacs (Scarpa et al. 2000, Urry et al. 2000). We present a comparative study of low redshift QSO and BL Lac host galaxy luminosity function (HGLF). To this aim we have considered samples of BL Lacs (Urry et al. 2000) and QSOs (Bahcall et al. 1997; Boyce et al. 1998; McLure et al. 1999) that have been well resolved by images obtained with WFPC2 on board of HST.

description: With dc magnetisation and polarized neutron reflectometry we studied the ferromagnetic response of YBa$_2$Cu$_3$O$_7$/La$_{2/3}$Ca$_{1/3}$MnO$_3$ (YBCO/LCMO) multilayers that are grown with pulsed laser deposition. We found that whereas for certain growth conditions (denoted as A-type) the ferromagnetic moment of the LCMO layer is strongly dependent on the structural details of the YBCO layer on which it is deposited, for others (B-type) the ferromagnetism of LCMO is much more robust. Both kinds of multilayers are of similar structural quality, but electron energy-loss spectroscopy (EELS) studies with a scanning transmission electron microscope reveal an enhanced average Mn oxidation state of +3.5 for the A-type as opposed to the B-type samples for which it is close to the nominal value of +3.33. The related, additional hole doping of the A-type LCMO layers, which likely originates from La and/or Mn vacancies, can explain their fragile ferromagnetic order since it places them close to the boundary of the ferromagnetic order at which even weak perturbations can induce an antiferromagnetic or glassy state. On the other hand, we show that the B-type samples allow one to obtain YBCO/LCMO heterostructures with very thick YBCO layers and, yet, strongly ferromagnetic LCMO layers.

From vacuum nonsingular black hole to variable cosmological constant

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We outline the class of globally regular spherically symmetric solutions to the minimally coupled GR equations asymptotically de Sitter in the origin and asymptotically Schwarzschild at infinity. A source term connects smoothly de Sitter vacuum at the regular center with Minkowski vacuum at infinity and corresponds to anisotropic spherically symmetric vacuum defined macroscopically by the algebraic structure of its stress-energy tensor invariant under boosts in the radial direction. De Sitter-Schwarzschild geometry describes a vacuum nonsingular black hole which evolves, in the course of Hawking evaporation, towards a self-gravitating particle-like structure without horizons, G-lump. Space-time symmetry changes smoothly from the de Sitter group in the center to the Lorentz group at infinity, and the standard formula for the ADM mass relates it to the de Sitter vacuum replacing a singularity at the scale of symmetry restoration. This class of metrics is easily extended to the case of a nonzero background cosmological constant. A source term connects then smoothly two de Sitter vacua with different values of cosmological constant which makes possible to associate anisotropic spherically symmetric vacuum with an r-dependent cosmological term.

The successful relations $|V_{us}| \approx \sqrt{m_u/m_c + m_d/m_s}$ and $|V_{td}/V_{ts}| \approx \sqrt{m_d/m_s}$ obtained previously from the six-zero texture of Hermitian quark mass matrices remain unchanged in the new ansatz.

description: This paper presents a qualitative assessment of the risk perceptions held by key Australian stakeholder groups in the context of tollroads operated under the Public-Private-Partnership model. The findings confirm that experience accumulated in recent years has contributed toward the betterment of risk sharing optimisation amongst the contracting parties. The knowledge acquired through in-depth interviews supports the common view that equitable risk-sharing is the vital ingredient of value for money. The proposition that the private sector is better equipped to manage commercial risks involving economic decision making whilst risks that have embedded unquantifiable social and public values and those in the domain of public governance are best left with government alone, appears to be replete with refutable implications. Public perception is a malleable concept and should be managed by both sectors.

description: We consider a cosmological scenario where a relativistic particle and a stable massive particle are simultaneously produced from the decay of a late-decaying particle after Big-Bang Nucleosynthesis but before matter-radiation equality. The relativistic and massive particles behave as dark radiation and warm dark matter, respectively. Due to a common origin, the warmness and abundances are closely related. We refer to the models that lead to such a scenario as Common Origin of Warm and Relativistic Decay Products (COWaRD). We show that COWaRD predicts a correlation between the amount of dark radiation and suppression of the large scale structure, which can be tested in future precision cosmology observations. We demonstrate that COWaRD is realized, as an example, in a class of supersymmetric axion models and that future observations by the next generation Cosmic Microwave Background, Large Scale Structure, and 21-cm surveys can reveal the structure of the theory.

description: We present a method for the construction of a Krein space completion for spaces of test functions, equipped with an indefinite inner product induced by a kernel which is more singular than a distribution of finite order. This generalizes a regularization method for infrared singularities in quantum field theory, introduced by G. Morchio and F. Strocchi, to the case of singularites of infinite order. We give conditions for the possibility of this procedure in terms of local differential operators and the Gelfand- Shilov test function spaces, as well as an abstract sufficient condition. As a model case we construct a maximally positive definite state space for the Heisenberg algebra in the presence of an infinite infrared singularity.

description: We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical. The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites. In the limit that the size of the matrix is large, the sites can collectively form a spatial manifold. The manifold is determined from the pattern of entanglement present across local Hilbert spaces associated with column vectors of the matrix. With no structure of manifold fixed in the background, the spacetime gauge symmetry is generalized to a group that includes diffeomorphism in arbitrary dimensions. The momentum and Hamiltonian that generate the generalized diffeomorphism obey a first-class constraint algebra at the quantum level. In the classical limit, the constraint algebra of the general relativity is reproduced as a special case. The first-class nature of the algebra allows one to express the projection of a quantum state of the matrix to a gauge-invariant state as a path integration of dynamical variables that describe collective fluctuations of the matrix. The collective variables describe dynamics of emergent spacetime, where multi-fingered times arise as Lagrangian multipliers that enforce the gauge constraints. If the quantum state has a local structure of entanglement, a smooth spacetime with well-defined dimension, topology, signature and geometry emerges at the saddle-point, and the spin two mode that determines the geometry can be identified. We find a saddle-point solution that describes a series of (3+1)-dimensional de Sitter-like spacetimes with the Lorentzian signature bridged by Euclidean spaces in between. Fluctuations of the collective variables are described by bi-local fields that propagate in the spacetime set up by the saddle-point solution.

description: We study the distributed Linear Quadratic Gaussian (LQG) control problem in discrete-time and finite-horizon, where the controller depends linearly on the history of the outputs and it is required to lie in a given subspace, e.g. to possess a certain sparsity pattern. It is well-known that this problem can be solved with convex programming within the Youla domain if and only if a condition known as Quadratic Invariance (QI) holds. In this paper, we first show that given QI sparsity constraints, one can directly descend the gradient of the cost function within the domain of output-feedback controllers and converge to a global optimum. Note that convergence is guaranteed despite non-convexity of the cost function. Second, we characterize a class of Uniquely Stationary (US) problems, for which first-order methods are guaranteed to converge to a global optimum. We show that the class of US problems is strictly larger than that of strongly QI problems and that it is not included in that of QI problems. We refer to Figure 1 for details. Finally, we propose a tractable test for the US property.

description: K-polystability is, on the one hand, conjecturally equivalent to the existence of certain canonical Kähler metrics on polarised varieties, and, on the other hand, conjecturally gives the correct notion to form moduli. We introduce a notion of stability for families of K-polystable varieties, extending the classical notion of slope stability of a bundle, viewed as a family of K-polystable varieties via the associated projectivisation. We conjecture that this is the correct condition for forming moduli of fibrations. Our main result relates this stability condition to Kähler geometry: we prove that the existence of an optimal symplectic connection implies semistability of the fibration. An optimal symplectic connection is a choice of fibrewise constant scalar curvature Kähler metric, satisfying a certain geometric partial differential equation. We conjecture that the existence of such a connection is equivalent to polystability of the fibration. We prove a finite dimensional analogue of this conjecture, by describing a GIT problem for fibrations embedded in a fixed projective space, and showing that GIT polystability is equivalent to the existence of a zero of a certain moment map.

description: In this paper, we address the efficient numerical solution of linear and quadratic programming problems, often of large scale. With this aim, we devise an infeasible interior point method, blended with the proximal method of multipliers, which in turn results in a primal-dual regularized interior point method. Application of this method gives rise to a sequence of increasingly ill-conditioned linear systems which cannot always be solved by factorization methods, due to memory and CPU time restrictions. We propose a novel preconditioning strategy which is based on a suitable sparsification of the normal equations matrix in the linear case, and also constitutes the foundation of a block-diagonal preconditioner to accelerate MINRES for linear systems arising from the solution of general quadratic programming problems. Numerical results for a range of test problems demonstrate the robustness of the proposed preconditioning strategy, together with its ability to solve linear systems of very large dimension.

description: This purposes of this report are to (1) help the California Department of Transportation (Caltrans) isolate causes of workplace backing collisions and (2) suggest methods of preventing backing incidents that result in accidents and injuries. While most backing collisions do not result in severe injuries, the large number of backing incidents make this type of crash a significant safety and cost problem. Data for the past 10 years was extracted from the Caltrans accident database and analyzed in order to isolate trends in backing-related collisions including incidence rates in comparison to other collision types, incident locations, and vehicle types, with particular attention to backing incidents reported as preventable. Backing crashes at Caltrans are deemed preventable when the driver could have averted the collision. Backing incidents represent the largest proportion of all preventable incidents at Caltrans; annually an average 30% of backing accidents are deemed preventable. After conducting an analysis of backing causal factors and incident trends, a thorough review of backing counter-measures at Caltrans was conducted. Based on an assessment of vehicle warning systems in place on Caltrans vehicles and of new developments in radar, sonar, video, and warning alarm devices, it was determined that video systems are a feasible technology that Caltrans should consider installing in several of its maintenance vehicles. Based on interviews with Caltrans district safety officers and a survey of safety management practices and policies, it was also determined that designing and enforcing systems of accountability are essential to ensuring employees follow backing safety protocol. Enforcement of driving related safety laws has been shown to have a significant effect on driver behavior because the general driving public has learned that there will be consequences for violating traffic laws through visible enforcement and publicity. The present review summarizes key findings on what backing-related technologies are most appropriate for the Caltrans fleet and reinforces the concept that implementing tougher enforcement policies and making safety and accountability key topics at tailgate and staff meetings will encourage a culture of workplace safety and will significantly reduce preventable backing accidents at Caltrans.

description: According to general relativity, the interaction of a matter field with gravitation requires the simultaneous introduction of a tetrad field, which is a field related to translations, and a spin connection, which is a field assuming values in the Lie algebra of the Lorentz group. These two fields, however, are not independent. By analyzing the constraint between them, it is concluded that the relevant local symmetry group behind general relativity is provided by the Lorentz group. Furthermore, it is shown that the minimal coupling prescription obtained from the Lorentz covariant derivative coincides exactly with the usual coupling prescription of general relativity. Instead of the tetrad, therefore, the spin connection is to be considered as the fundamental field representing gravitation.

description: Cliquet options are widely traded in many retail-structured products. They consist of financial derivatives which provide a guaranteed minimum return in exchange for a capping of the maximal return over the life of the contract. A cliquet option is equivalent to a series of forward-starting at-the-money options, which may be globally and locally floored and capped.

description: India has an alarming rate of growth of cardiovascular diseases (CVD). Similar to cancer there is a significant role for epigenetic factors in the increasing prevalence of CVD. Targeting the epigenetic mechanism, viz., the DNA methylation processes, histone modifications, and RNA based arrangements is today considered as a potential therapeutic approach to CVD management. 5-Azacytidine is an epigenetic treatment drug that is involved in the demethylation of DNA. 5-Azacytidine is an FDA approved drug for myelodysplastic syndrome. However, the usage of 5-Azacytidine for CVD has not been found acceptable because of its poor stability in neutral solutions and shorter half-live which makes it toxic to the cells. A significant breakthrough in the use of 5-azacytidine for cell therapy and tissue engineering for CVD treatment has been gained based on its ability to differentiate mesenchymal stem cells into cardiomyocytes. This work addresses the further need for a sustained release of this drug, to reduce its toxicity to the stem cells. Electrospun PCL-gelatin fibres that are well aligned to provide a mat-like structure with sufficient porosity for differentiated cells to move forward have been synthesized. The crystalline character, porosity, fibre width, thermal behavior hydrophilicity of these scaffolds are in tune with those reported in the literature as ideal for cell proliferation and adhesion. FTIR measurements confirm the entrapment of 5-azacytidine on to the scaffold. The adsorption of the drug did not alter the characteristic features of the scaffold. Primary results on cell viability and cell morphology, as well as cardiomyocyte differentiation, have shown that PCL-gelatin scaffolds carrying 5-azacytidine developed in this work could serve as an ideal platform for mesenchymal stem cell differentiation into cardiomyocytes.

description: While research in the United States has consistently shown that freeway fatality rates increase with higher speed limits, freeway fatality rates in Germany with no general speed limit on the autobahns are about the same as they are in the United States. The paper explores different contributing factors which might explain this mystery and which lessons of interest to US freeway operations might be learned. It surmises that a very strict separation of traffic by speed (lane discipline) in Germany as opposed to the US might be the main explanatory factor for the low sensitivity of fatality rates to changes in speed limits in Germany versus a very high sensitivity in the United States.

description: We propose a novel approach of probing grand unification through precise measurements on the Higgs Yukawa couplings at the LHC. This idea is well motivated by the appearance of effective operators not suppressed by the mass scale of unification $M_{\rm{U}}$ in realistic models of unification with the minimal structure of Yukawa sector. Such operators modify the Higgs Yukawa couplings in correlated patterns at scale $M_{\rm{U}}$ that hold up to higher-order corrections. The coherences reveal a feature that, the deviation of tau Yukawa coupling relative to its standard model value at the weak scale is the largest one among the third-generation Yukawa couplings. This feature, if verified by the future LHC, can serve as a hint of unification.
