description: The propagation of focused wave groups in intermediate water depth and the shoaling zone is experimentally and numerically considered in this paper. The experiments are carried out in a two-dimensional wave flume and wave trains derived from Pierson-Moskowitz and JONSWAP spectrum are generated. The peak frequency does not change during the wave train propagation for Pierson-Moskowitz waves; however, a downshift of this peak is observed for JONSWAP waves. An energy partitioning is performed in order to track the spatial evolution of energy. Four energy regions are defined for each spectrum type. A nonlinear energy transfer between different spectral regions as the wave train propagates is demonstrated and quantified. Numerical simulations are conducted using a modified Boussinesq model for long waves in shallow waters of varying depth. Experimental results are in satisfactory agreement with numerical predictions, especially in the case of wave trains derived from JONSWAP spectrum.

description: We report the detection of emission in the v=1-0 P(1) (3.51629 micron) and P(2) (3.60776 micron) rovibrational lines of the helium hydride cation (HeH+) from the planetary nebula NGC 7027. These detections were obtained with the iSHELL spectrograph on NASA's Infrared Telescope Facility (IRTF) on Maunakea. The confirm the discovery of HeH+ reported recently by Guesten et al. (2019), who used the GREAT instrument on the SOFIA airborne observatory to observe its pure rotational J=1-0 transition at 149.137 micron. The flux measured for the HeH+ v=1-0 P(1) line is in good agreement with our model for the formation, destruction and excitation of HeH+ in NGC 7027. The measured strength of the J=1-0 pure rotational line, however, exceeds the model prediction significantly, as does that of the v=1-0 P(2) line, by factors of 2.9 and 2.3 respectively. Possible causes of these discrepancies are discussed. Our observations of NGC 7027, covering the 3.26 - 3.93 micron spectral region, have led to the detection of more than sixty spectral lines including nine rovibrational emissions from CH+. The latter are detected for the first time in an astronomical source.

description: We present an analytical method for constraining the substellar initial mass function in globular clusters, based on the observed frequency of transit events. Globular clusters typically have very high stellar densities where close encounters are relatively common, and thus tidal capture can occur to form close binary systems. Encounters between main sequence stars and lower-mass objects can result in tidal capture if the mass ratio is > 0.01. If brown dwarfs exist in significant numbers, they too will be found in close binaries, and some fraction of their number should be revealed as they transit their stellar companions. We calculate the rate of tidal capture of brown dwarfs in both segregated and unsegregated clusters, and find that the tidal capture is more likely to occur over an initial relaxation time before equipartition occurs. The lack of any such transits in recent HST monitoring of 47 Tuc implies an upper limit on the frequency of brown dwarfs (< 15 % relative to stars) which is significantly below that measured in the galactic field and young clusters.

description: Purpose: Even in cases of positive evidence for complementary medicine (CM) therapies, it is still difficult for cancer patients to identify reputable providers. The aim of this study was to develop and evaluate a criteria list to provide guidance to cancer patients seeking a reputable CM provider. Methods: The design combined a literature review, an expert consensus procedure (n=15) and an assessment from three stakeholder perspectives (patients (n=18), CM providers (n=26) and oncology physicians (n=20)). Results: A total of 30 existing CM criteria were extracted from the literature, and 12 more were added by the experts. The main challenge was to define criteria that could easily be applied by the patients. A final comprehensive list of 8 criteria guiding cancer patients to find a reputable CM provider was developed. Conclusion: Health professionals and cancer information services might find the criteria list helpful when aiming to strengthen patients' awareness of quality-related factors associated with CM providers. The criteria developed might be helpful when standards are established for quality assurance in CM in oncology.

description: The paper takes theatre as its optic to help expand and illuminate extant perceptions about corpses, burials, and cemeteries. The first part of the paper is dedicated to the methods of and purposes for burying the corpse in the context of theories expounded by Sigmund Freud, Bronislaw Malinowski, and Julia Kristeva. Throughout the paper, cemeteries are regarded not only as formal and religious places where the remains of the dead are interred but also as sites of action and observation – the sites where the veiling and unveiling of the remains take place. The arguments are further examined through the work of French playwright Jean Genet, especially in the light of his play The Screens and his essay ‘That strange word…’, which can be regarded either as Genet’s site-specific plan for staging The Screens or as his reflection on the significance of theatre in general.

description: An electro-swirling coupling device coupled with electric field and centrifugation can achieve demulsification and dewatering of emulsion efficiently and economically. But, the vortex structure and its implication on separation performance under the coupling condition are unclear. Accordingly, a vortex analysis for the coupling separator was conducted numerically, and the effect of eccentricity on the efficiency was investigated. The results show that the iso-vortex surface is twisted and fluctuates. And there is a vibrational radial deviation between the vortex core and central axis, and increasing inlet velocity and voltage amplitude can increase the radial deviation of the vortex at the z-coordinate range from 250 to 550 mm. Furthermore, the underlying reason for the increase in vortex eccentricity is different where the electric coalescence is for the increase in voltage amplitude and the fluid kinetic energy is for the increase in inlet velocity. Moreover, the separation efficiency increases with the increase in vortex eccentricity at the case that the coalescence is dominant, but the separation efficiency gradually decreases with the increase in breakage rate and the droplet breakup is dominant.
Quantum Space, Quantum Time, and Relativistic Quantum Mechanics

description: We treat space and time as bona fide quantum degrees of freedom on an equal footing in Hilbert space. Motivated by considerations in quantum gravity, we focus on a paradigm dealing with linear, first-order Hamiltonian and momentum constraints that lead to emergent features of temporal and spatial translations. Unlike the conventional treatment, we show that Klein-Gordon and Dirac equations in relativistic quantum mechanics can be unified in our paradigm by applying relativistic dispersion relations to eigenvalues rather than treating them as operator-valued equations. With time and space being treated on an equal footing in Hilbert space, we show symmetry transformations to be implemented by unitary basis changes in Hilbert space, giving them a stronger quantum mechanical footing. Global symmetries, such as Lorentz transformations, modify the decomposition of Hilbert space; and local symmetries, such as $U(1)$ gauge symmetry are diagonal in coordinate basis and do not alter the decomposition of Hilbert space. We briefly discuss extensions of this paradigm to quantum field theory and quantum gravity.

description: Introduction: This case of a mother and her two children, born 20 years apart, highlights how Biological Nurturing (BN) supported a woman in meeting her personal breastfeeding goals. We know lack of breastfeeding support contributes to early weaning. Applying the principles of BN (unrestricted and laid-back breastfeeding) enabled this mother to return to breastfeeding without supplements. Main issue: After giving birth to her first son prematurely in 1997, the dyad was separated, and formula introduced. These interventions, combined with inadequate breastfeeding support, resulted in low milk supply and unplanned weaning by week six. In 2017, a full term sibling baby girl was born, with breastfeeding again beginning with concerns of low milk supply. Management: Consultation with an International Board Certified Lactation Consultant successfully addressed common breastfeeding problems, including vasospasm and insufficient milk supply. Continuous emotional support helped this mother overcome perceived insufficient milk supply. Introducing BN led to breastfeeding without supplementation, by enabling the dyad to experience enjoyment, comfort and feeding autonomy. Conclusion: While the repeated experience of insufficient milk supply two decades apart constituted a psychological barrier to exclusive breastfeeding, BN enabled reaching this mother's breastfeeding goals. BN appears to be a powerful tool for both breastfeeding initiation and overcoming breastfeeding difficulties, potentially setting new best practice standards.

description: Terahertz (THz)-based electron acceleration and manipulation has recently been shown to be feasible and to hold tremendous promise as a technology for the development of next-generation, compact electron sources. Previous work has concentrated on structures powered transversely by short, single-cycle THz pulses, with mm-scale, segmented interaction regions that are ideal for acceleration of electrons in the sub- to few-MeV range where electron velocities vary significantly. However, in order to extend this technology to the multi-MeV range, investigation of approaches supporting longer interaction lengths is needed. Here, we demonstrate first steps in electron acceleration and manipulation using dielectrically-lined waveguides powered by temporally long, narrowband, multi-cycle THz pulses that co-propagate with the electrons. This geometry offers centimeter-scale single-stage interaction lengths and offers the opportunity to further increase interaction lengths by cascading acceleration stages that recycle the THz energy and rephase the interaction. We prove the feasibility of THz-energy recycling for the first time by demonstrating acceleration, compression and focusing in two sequential Al2O3-based dielectric capillary stages powered by the same multi-cycle THz pulse. Since the multi-cycle energy achievable using laser-based sources is currently a limiting factor for the maximum electron acceleration, THz energy recycling provides a key enabling factor for reaching relativistic energies with existing sources.

description: The prevalence of smoking amongst the study groups was low as compared to the natives of Saudi Arabia as well as to that among the students of the neighboring countries. The majority of medical and dental students held positive attitudes towards smoking prevention. The colleges’ role in the prevention and control of smoking turned out to be inadequate. The colleges either did not have a policy imposing ban on smoking or the students were not aware of it. About half of smokers thought that smoking had a stress‐relieving effect in their case. A substantial number of smokers used to enjoy smoking during their leisure.
Surface photon emissivity of bare strange stars

description: We consider the bremsstrahlung surface photon emissivity of strange quark stars, by sistematically taking into account the effects of the multiple scatterings of the highly relativistic quarks in a dense medium (the Landau-Pomeranchuk-Migdal effect). Due to interference between amplitudes of nearby interactions, the bremsstrahlung emissivity from strange star surface is suppressed for frequencies smaller than a critical frequency. The range of the suppressed frequencies is a function of the quark matter density at the star's surface and of the QCD coupling constant. For temperatures much smaller than the Fermi energy of the quarks the bremsstrahlung spectrum has the same temperature dependence as the equilibrium black body radiation. Multiple collisions could reduce the intensity of the bremsstrahlung radiation by an order of magnitude. The effect of the thin electron layer at the surface of the quark star on the bremsstrahlung spectrum is also analyzed in detail. It is shown that absorption in the semi-degenerate electron gas can also significantly reduce the intensity of the quark-quark bremsstrahlung radiation and, consequently, the surface emissivity. Hence the combined effects of multiple collisions and absorption in the electron layer could make the soft photon surface radiation of quark stars six orders of magnitude smaller than the equilibrium black body radiation.

description: We prove that almost every level set of a Sobolev function in a planar domain consists of points, Jordan curves, or homeomorphic copies of an interval. For monotone Sobolev functions in the plane we have the stronger conclusion that almost every level set is an embedded $1$-dimensional topological submanifold of the plane. Here monotonicity is in the sense of Lebesgue: the maximum and minimum of the function in an open set are attained at the boundary. Our result is an analog of Sard's theorem, which asserts that for a $C^2$-smooth function in a planar domain almost every value is a regular value. As an application we show that monotone Sobolev functions in planar domains can be approximated uniformly and in the Sobolev norm by smooth monotone functions.

Ferromagnetism in Mn doped GaAs due to substitutional-interstitial complexes

description: While most calculations on the properties of the ferromagnetic semiconductor GaAs:Mn have focussed on isolated Mn substituting the Ga site (Mn$_{Ga}$), we investigate here whether alternate lattice sites are favored and what the magnetic consequences of this might be. Under As-rich (Ga-poor) conditions prevalent at growth, we find that the formation energies are lower for Mn$_{Ga}$ over interstitial Mn (Mn$_i$).As the Fermi energy is shifted towards the valence band maximum via external $p$-doping, the formation energy of Mn$_i$ is reduced relative to Mn$_{Ga}$. Furthermore, under epitaxial growth conditions, the solubility of both substitutional and interstitial Mn are strongly enhanced over what is possible under bulk growth conditions. The high concentration of Mn attained under epitaxial growth of p-type material opens the possibility of Mn atoms forming small clusters. We consider various types of clusters, including the Coulomb-stabilized clusters involving two Mn$_{Ga}$ and one Mn$_i$. While isolated Mn$_i$ are hole killers (donors), and therefore destroy ferromagnetism,complexes such as Mn$_{Ga}$-Mn$_i$-Mn$_{Ga}$) are found to be more stable than complexes involving Mn$_{Ga}$-Mn$_{Ga}$-Mn$_{Ga}$. The former complexes exhibit partial or total quenching of holes, yet Mn$_i$ in these complexes provide a channel for a ferromagnetic arrangement of the spins on the two Mn$_{Ga}$ within the complex. This suggests that ferromagnetism in Mn doped GaAs arises both from holes due to isolated Mn$_{Ga}$ as well as from strongly Coulomb stabilized Mn$_{Ga}$-Mn$_i$-Mn$_{Ga}$ clusters.

description: With real-time certificate validation checking, a public-key-using system that needs to validate a certificate executes a transaction with a specialized validation party. At the end of the transaction the validation party returns an indication about the validity status of the certificate. This paper analysis the public key (PbK) certificate validation service from a practical point of view by describing the implementation of a system that makes use of the Data Validation and Certification Server (DVCS) protocols to provide certificate validation service to the Relying Parties (RPs). However the system is not restricted to use only the specified protocol and allows the integration of other validation protocols or mechanisms. Our implementation efforts emphasize the possibility to pursue a specific RP tradeoff between timeliness, security and computational resource usage via dynamic selection of several configurable options.

description: Two 75mm 4H-SiC single crystals are grown by the physical vapor transport (PVT) technique, using different insulation materials. The insulation material of higher thermal conductivity led to an increased radial temperature gradient. The evolution of the growth front was monitored using the in-situ computed tomography (CT). A slightly bent growth interface and a bigger facet are formed during the growth applying a lower radial temperature gradient while a smaller facet and steeper crystal flanks are formed in the case of the larger radial temperature gradient. Micropipes are deflected laterally by large surface steps on the steep crystal flanks and a reduction of threading edge dislocations by 60% is revealed by KOH defect etching.

description: We study in optimal control the important relation between invariance of the problem under a family of transformations, and the existence of preserved quantities along the Pontryagin extremals. Several extensions of Noether theorem are provided, in the direction which enlarges the scope of its application. We formulate a more general version of Noether's theorem for optimal control problems, which incorporates the possibility to consider a family of transformations depending on several parameters and, what is more important, to deal with quasi-invariant and not necessarily invariant optimal control problems. We trust that this latter extension provides new possibilities and we illustrate it with several examples, not covered by the previous known optimal control versions of Noether's theorem.

description: There has been a lot of controversy about the current mammography screening program. Screening recommendations for breast cancer in Germany are currently based solely on age and gender of an individual, despite the fact that additional genetic and non-genetic factors are known to influence cancer risk. Recent breast cancer risk models include these factors. They would allow the implication of a risk adapted screening approach, “Mammography Screening 2.0”. On the one hand there is a need to intensify diagnostic procedures for women at higher risk; on the other hand it is desired to avoid unnecessary diagnostic procedures in women who are unlikely to develop breast cancer. The aim is to improve the efficiency of the screening program and to help guide screening decisions by patients’ individual risk profiles and preferences. However, the implementation of such a strategy faces new challenges, such as the choice of the adequate prediction model, the interpretation of the results, and the ways to communicate the risks. We could show that currently used risk models, such as IBIS and BOADICEA, are well calibrated and conclusively already provide a useful perspective for individualized screening as they perform more effectively than considering age alone. Our ultimate goal is to categorize women according to their risk of breast cancer as accurately as possible, based on their profile of genetic and non-genetic risk factors, and to recommend a more individualized screening program. However, at the moment we do not have an international agreement how best to define for breast cancer the “high risk” group. We recommend that physicians use time periods of briefer duration, such as 5 or 10-year risks to identify women at high risk. Appropriate risk communication in Mammography Screening 2.0 will present a new but interesting challenge for physicians. There is a need to implement shared decision-making in routine medical practice, and also a need for fundamental schemes for risk communication. In conclusion our research shows that an individualized risk adapted screening strategy is feasible and of advantage in clinical practice. Our research could contribute to the evidence required to overcome any barriers associated with replacing the current “all inclusive” age related screening guidelines with a more focused individualized approach, which requires medical counseling.

description: We present the results of numerical simulations of an atomistic system undergoing plastic shear flow in the athermal, quasistatic limit. The system is shown to undergo cascades of local rearrangements, associated with quadrupolar energy fluctuations, which induce system-spanning events organized into lines of slip oriented along the Bravais axes of the simulation cell. A finite size scaling analysis reveals subextensive scaling of the energy drops and participation numbers, linear in the length of the simulation cell, in good agreement with the observed real-space structure of the plastic events.

description: We derive the semiclassical equation of motion for the wave-packet of light taking into account the Berry curvature in the momentum space. This equation naturally describes the interplay between the orbital and spin angular momenta, i.e., the conservation of the total angular momentum of light. This leads to the shift of the wave-packet motion perpendicular to the gradient of the dielectric constant, i.e., the polarization-dependent Hall effect of light. An enhancement of this effect in the photonic crystal is also proposed.

Following previous publications in the field, we argue that what the algorithm does with such solutions and how often this has to happen is important for the overall performance of the algorithm and interpretation of results. Based on observations therein, we conclude that significantly more solutions than what is usually assumed by practitioners need to undergo some sort of 'correction' to conform with the definition of the problem's search domain. A wide range of popular Differential Evolution configurations is considered in this study. Conclusions are made regarding the effect the Differential Evolution components and parameter settings have on the distribution of proportions of infeasible solutions generated in a series of independent runs. Results shown in this study suggest strong dependencies between proportions of generated infeasible solutions and every aspect mentioned above. Further investigation of the distribution of proportions of generated infeasible solutions is required.

description: We are undertaking a large-scale, Micro-Arcsecond Scintillation-Induced Variability (MASIV) survey of the northern sky, Dec > 0 deg, at 4.9 GHz with the VLA. Our objective is to construct a sample of 100 to 150 scintillating extragalactic sources with which to examine both the microarcsecond structure and the parent populations of these sources, and to probe the turbulent interstellar medium responsible for the scintillation. We report on our first epoch of observations which revealed variability on timescales ranging from hours to days in 85 of 710 compact flat-spectrum sources. The number of highly variable sources, those with RMS flux density variations greater than 4% of the mean, increases with decreasing source flux density but rapid, large amplitude variables such as J1819+3845 are very rare. When compared with a model for the scintillation due to irregularities in a 500 pc thick electron layer, our preliminary results indicate maximum brightness temperatures ~10E+12 K, similar to those obtained from VLBI surveys even though interstellar scintillation is not subject to the same angular resolution limit.

The coping roles of offspring of alcohol dependants : their measurement and validity

description: In an attempt to bridge the gap between clinical and empirical research on the children of alcohol dependents (COAs), the present study examined the extent to which supposedly dysfunctional role prescribed behaviour was linked with the seriousness of problem drinking in the family. Specifically, the study investigated Wegscheider and Black's contention that COAs adopt one or more of the roles of family hero, scapegoat, lost child, mascot and placater. The contribution of parental drinking behaviour to role adoption was examined by controlling for the confounding risk factor of family disorganization. Data were obtained through a self-completion questionnaire administered to a sample of adolescents within the Canberra community. Parental drinking behaviour was assessed using the Children of Alcoholics Screening Test (CAST), and the Coping Role Instrument developed from the writings of Wegscheider and Black. Structural analyses of the interrelationships of items representing each role provided qualified support for the typology, with the need to define types more specifically. The pattern of intercorrelations among roles indicated that if respondents were likely to adopt any role to a degree, they were also likely to adopt other roles. While parental drinking could be linked to adoption of three roles (hero, scapegoat and placater), family disorganization was also found to be an important predictor of role adoption. Low family cohesiveness was the major predictor of whether adolescents would adopt the mascot or lost child roles. The study concluded that coping role behaviour is not peculiar to COAs, occurring among adolescents as a response to threat generally. Congruent with notions from the stress literature, it was suggested that while parental drinking may represent a significant stressor for offspring, its effects must be considered as a complex interplay with other family environment and offspring variables.

description: Glioblastoma (GBM) present with an abundant and aberrant tumor neo-vasculature. While rapid growth of solid tumors depends on the initiation of tumor angiogenesis, GBM also progress by infiltrative growth and vascular co-option. The angiogenic factor apelin (APLN) and its receptor (APLNR) are upregulated in GBM patient samples as compared to normal brain tissue. Here, we studied the role of apelin/APLNR signaling in GBM angiogenesis and growth. By functional analysis of apelin in orthotopic GBM mouse models, we found that apelin/APLNR signaling is required for in vivo tumor angiogenesis. Knockdown of tumor cell-derived APLN massively reduced the tumor vasculature. Additional loss of the apelin signal in endothelial tip cells using the APLN-knockout (KO) mouse led to a further reduction of GBM angiogenesis. Direct infusion of the bioactive peptide apelin-13 rescued the vascular loss-of-function phenotype specifically. In addition, APLN depletion massively reduced angiogenesis-dependent tumor growth. Consequently, survival of GBM-bearing mice was significantly increased when APLN expression was missing in the brain tumor microenvironment. Thus, we suggest that targeting vascular apelin may serve as an alternative strategy for anti-angiogenesis in GBM.
Exclusive production of $ϕ$ meson in the $γ^*\,p \to ϕ\,p$ reaction at large photon virtualities within $k_T$-factorization approach

description: We apply the $k_T$-factorization approach to the production of $ϕ$ meson in deep-inelastic scattering. The helicity-conserving $γ^*(T,L) \to ϕ$ impact factor is calculated for longitudinal and transverse photon polarization using $ϕ$ meson distribution amplitudes. Different unintegrated gluon distributions are used in the calculations. The formalism for massless quarks/antiquarks gives too large transverse and longitudinal cross sections for photon virtualities below $Q^2\sim 8 \, \rm{GeV}^2$. We suggest how to improve the description of the HERA data by introducing effective strange quark masses into the formalism. We derive the corresponding massive impact factor by comparing to the light-cone wave function representation used in previous $k_T$-factorization calculations and the color-dipole approaches. As a byproduct we present expressions for higher twist-amplitudes as weighted integrals over the light-cone wave function. The quark mass $m_q \approx 0.5$ GeV allows to improve the description of both longitudinal and transverse cross section down to $Q^2 \sim$ 4 GeV$^2$. We present also the polarized cross section ratio $σ_L/σ_T$ and the behavior of the total cross section $σ_{tot} = σ_{L} + σ_{T}$ as a function of photon virtuality.

description: In the 21st century, few pieces of management are still intact from history, and one of them is strategic management. There have been many studies on strategic management, and the majority of the scholars have squared to three-step strategic management. This article narrates an empirical case study of mismanagement that occurred at Citizens Telecom, which is costing the jobs of four consultant telecom engineers from the Design Services Company. The design lead, Omair, asks the team to submit their thoughts and ideas on three-step strategic management; Planning, Implementation, and Monitoring. This article is the second half of the case study that describes the implementation step of the three-step strategic management process. Omair proposes three options of implementation step to the management that yields a similar result. The article concludes with the importance of strategic management in every department to either improve the existing processes or fix the current issues. Lastly, the author leaves the monitoring step for the readers to identify. Keywords: Information Technology; Business Management; IT Budget; Implementation; Job Security; Strategic Management.

description: In this paper we verify that the graph forms a complete invariant for Banach algebra isomorphisms of tensor algebras of graphs. For tensor algebras associated with countable directed graphs having no sinks the graph forms an invariant for algebraic isomorphisms as well. The graph also forms a complete invariant for w*-bicontinuous isomorphisms of free semigroupoid algebras. For free semigroupoid algebras associated with countable directed locally finite graphs with no sinks, the graph also forms an invariant for algebraic isomorphisms.

description: Let $(\mathcal{C},\mathbb{E},\mathfrak{s})$ be an extriangulated category with a proper class $ξ$ of $\mathbb{E}$-triangles, and $\mathcal{W}$ an additive full subcategory of $\mathcal C$. We provide a method for constructing a proper $\mathcal{W}(ξ)$-resolution (respectively, coproper $\mathcal{W}(ξ)$-coresolution) of one term in an $\mathbb{E}$-triangle in $ξ$ from that of the other two terms. By using this way, we establish the stability of the Gorenstein category $\mathcal{GW}(ξ)$ in extriangulated categories. These results generalise their work by Huang and Yang-Wang, but the proof is not too far from their case. Finally, we give some applications about our main results.
