description: We present a quantum version of the generalized $(h,ϕ)$-entropies, introduced by Salicrú \textit{et al.} for the study of classical probability distributions. We establish their basic properties, and show that already known quantum entropies such as von Neumann, and quantum versions of Rényi, Tsallis, and unified entropies, constitute particular classes of the present general quantum Salicrú form. We exhibit that majorization plays a key role in explaining most of their common features. We give a characterization of the quantum $(h,ϕ)$-entropies under the action of quantum operations, and study their properties for composite systems. We apply these generalized entropies to the problem of detection of quantum entanglement, and introduce a discussion on possible generalized conditional entropies as well.

description: We explore the phase behavior and structure of orthogonal smectic liquid crystals consisting of bent-core molecules (BCMs) by means of Monte Carlo molecular simulations. A simple athermal molecular model is introduced that describes the basic features of the BCMs. Phase transitions between uniaxial and biaxial (antiferroelectric) orthogonal smectics are obtained. The results indicate the presence of local in-plane polar correlations in the uniaxial smectic phase. The macroscopic uniaxial-biaxial transformation is rationalized in terms of local polar correlations giving rise to polar domains. The size of these polar domains grows larger under the action of an external vector field and their internal ordering is enhanced, leading to field-induced biaxial order-disorder transitions.

description: Little is known about relationships between a positive family history of breast cancer, perception of risk, and lifestyle behaviors. This qualitative study explored factors involved in formulation of perceived breast cancer risk and the association between risk perception and lifestyle behaviors in white and black women with a family history of breast cancer. Eligible participants were North Carolina residents in the Sister Study, a nationwide study of environmental and genetic risk factors for breast cancer among women aged 35 to 74 who have at least one sister diagnosed with breast cancer. Personal interviews were conducted with thirty-two women, twenty white and twelve black. While many had a heightened sense of risk and perceived family history as a main risk factor, 16% considered themselves at low or average risk for breast cancer and Gail risk scores did not correspond to perceived risk. Many women were unaware of associations between lifestyle behaviors and breast cancer risk. Eleven women, six black and five white, reported making healthy lifestyle changes because of family history; dietary change was most frequently reported. These findings may be important for future developers of breast cancer education programs for both white and black women with a family history of breast cancer.

description: Prostate cancer prognosis may be improved by healthy behaviors; however, little is known regarding whether prostate cancer survivors make health behavior changes post-diagnosis, and there is no data on racial/ethnic differences. This study explored patterns of, and factors that influence healthy behavior changes in diet, physical activity, and dietary supplement use among whites and African Americans (n=30), 45–70 years, ≅1 year after diagnosis with localized prostate cancer. Data were collected by telephone using semi-structured qualitative interviews. The mean participant age was 59.6 years, 77% had attended college, 87% were married, and 22% were retired. The majority (58%) had improved their diet since diagnosis, defined as eating more fruits/vegetables and less fat. Although 77% reported regular use of at least one dietary supplement before diagnosis, several discontinued use post-diagnosis. Sixty-seven percent exercised regularly before diagnosis and most of these (75%) continued post-diagnosis; however, time and health constraints were barriers. Physician recommendation and family support strongly influenced positive changes. Except for more post-diagnosis dietary improvements in African Americans, there were few racial differences in patterns/motives for behavior changes. Most respondents were motivated to maintain and/or adopt healthy behavioral changes post-diagnosis. Nurses/physicians are encouraged to inform their prostate cancer patients about the benefits of healthy eating and regular exercise and the absence of scientific evidence regarding the benefits/risks of most supplements, particularly herbal formulations.

description: We investigate the shadow cast by a regular black hole in scalar-tensor-vector mOdified gravity theory. This black hole differs from a Schwarzschild-Kerr black hole by the dimensionless parameter $β$. The size of the shadow depends on this parameter. Increasing the value of the parameter $β$ shrinks the shadow. A critical value of the parameter $β$ is found to be $β_{\rm crit}=0.40263$. The shadow for the horizonless dark compact object has been analysed for the static, spherically symmetric case and compared with M87* and Sgr A* data. Shadow observables have been determined in the context of the regular black hole and used for obtaining the energy emission rate. The peak of the energy emission rate shifts to lower frequency for the increasing value of the parameter $β$.

description: This special issue collects contributions from the participants of the "Information in Dynamical Systems and Complex Systems" workshop, which cover a wide range of important problems and new approaches that lie in the intersection of information theory and dynamical systems. The contributions include theoretical characterization and understanding of the different types of information flow and causality in general stochastic processes, inference and identification of coupling structure and parameters of system dynamics, rigorous coarse-grain modeling of network dynamical systems, and exact statistical testing of fundamental information-theoretic quantities such as the mutual information. The collective efforts reported herein reflect a modern perspective of the intimate connection between dynamical systems and information flow, leading to the promise of better understanding and modeling of natural complex systems and better/optimal design of engineering systems.
Low-energy singlet excitations in spin- 1/2 Heisenberg antiferromagnet on square lattice

description: We present an approach based on a dimer expansion which describes low-energy singlet excitations (singlons) in spin-$\frac12$ Heisenberg antiferromagnet on simple square lattice. An operator ("effective Hamiltonian") is constructed whose eigenvalues give the singlon spectrum. The "effective Hamiltonian" looks like a Hamiltonian of a spin-$\frac12$ magnet in strong external magnetic field and it has a gapped spectrum. It is found that singlet states lie above triplet ones (magnons) in the whole Brillouin zone except in the vicinity of the point $(π,0)$, where their energies are slightly smaller. Based on this finding, we suggest that a magnon decay is possible near $(π,0)$ into another magnon and a singlon which may contribute to the dip of the magnon spectrum near $(π,0)$ and reduce the magnon lifetime. It is pointed out that the singlon-magnon continuum may contribute to the continuum of excitations observed recently near $(π,0)$.

description: To define a free string by the Nambu-Goto action, all we need is the notion of area, and mathematically the area can be defined directly in the absence of a metric. Motivated by the possibility that string theory admits backgrounds where the notion of length is not well defined but a definition of area is given, we study space-time geometries based on the generalization of metric to area metric. In analogy with Riemannian geometry, we define the analogues of connections, curvatures and Einstein tensor. We propose a formulation generalizing Einstein's theory that will be useful if at a certain stage or a certain scale the metric is ill-defined and the space-time is better characterized by the notion of area. Static spherical solutions are found for the generalized Einstein equation in vacuum, including the Schwarzschild solution as a special case.

We point out that Perloff and Shen's (2012) proof is incorrect and its simulation setting is invalid. Our simulation shows that estimation becomes accurate when demand shifters are properly added in supply estimation and sample sizes are increased, supporting Bresnahan (1982).

description: SBES - Education Track Software Engineering (SE) is a discipline that deals with aspects of software production.
 Often, only the technical aspects are taught in the classes, and the economic and social aspects involved in software development are not reinforced in the classroom.
 In this context, the concept of a Software Ecosystem (SECO) emerged, defined as a set of actors acting as a unit interacting with a market distributed between software and services, with relationships supported by a technological platform or a common market, carried out by exchanging information, artifacts and resources.
 SECO teaching is not common in SE classes.
 However, when adding this knowledge, it is possible to have the benefit of a more global vision of SE, with the relationships between suppliers, technological platforms and customers.
 Moreover, there is a lack of SECO models and examples in the literature, making its study difficult.
 This article presents the ARIEL tool, with the aim of mitigating this gap and supporting the teaching of SECO in SE.
 For this, an user experience evaluation was projected using the DECIDE framework as a reference, with undergraduate and graduate students.
 As a result of this work, the participants stated it was easy to use the tool and they made few mistakes, most of them felt satisfied when using the tool, and the level of mental effort to carry out the activities is low.
Efficient learning of ground & thermal states within phases of matter

description: We consider two related tasks: (a) estimating a parameterisation of a given Gibbs state and expectation values of Lipschitz observables on this state; and (b) learning the expectation values of local observables within a thermal or quantum phase of matter. In both cases, we wish to minimise the number of samples we use to learn these properties to a given precision.
 For the first task, we develop new techniques to learn parameterisations of classes of systems, including quantum Gibbs states of non-commuting Hamiltonians with exponential decay of correlations and the approximate Markov property. We show it is possible to infer the expectation values of all extensive properties of the state from a number of copies that not only scales polylogarithmically with the system size, but polynomially in the observable's locality -- an exponential improvement. This set of properties includes expected values of quasi-local observables and entropies.
 For the second task, we develop efficient algorithms for learning observables in a phase of matter of a quantum system. By exploiting the locality of the Hamiltonian, we show that $M$ local observables can be learned with probability $1-δ$ to precision $ε$ with using only $N=O\big(\log\big(\frac{M}δ\big)e^{polylog(ε^{-1})}\big)$ samples -- an exponential improvement on the precision over previous bounds. Our results apply to both families of ground states of Hamiltonians displaying local topological quantum order, and thermal phases of matter with exponential decay of correlations. In addition, our sample complexity applies to the worse case setting whereas previous results only applied on average.
 Furthermore, we develop tools of independent interest, such as robust shadow tomography algorithms, Gibbs approximations to ground states, and generalisations of transportation cost inequalities for Gibbs states.

description: The past decade has witnessed the unveiling of a powerful new generation of genetically-engineered mouse (GEM) models of human cancer, which are proving to be highly effective for elucidating cancer mechanisms and interrogating novel experimental therapeutics. This new generation of GEM models are well-suited for chemoprevention research, particularly for investigating progressive stages of carcinogenesis, identifying biomarkers for early detection and intervention, and pre-clinical assessment of novel agents or combinations of agents. Here we discuss opportunities and challenges for the application of GEM models in prevention research, as well as strategies to maximize their relevance for human cancer.

description: Approximating nonlinear dynamics with a truncated perturbative expan- sion may be accurate for a while, but it in general breaks down at a long time scale that is one over the small expansion parameter. There are interesting occasions in which such breakdown does not happen. We provide a mathematically general and precise definition of those occasions, in which we prove that the validity of truncated theory trivially extends to the long time scale. This enables us to utilize numerical results, which are only obtainable within finite times, to legitimately predict the dynamic when the expansion parameter goes to zero, thus the long time scale goes to infinity. In particular, this shows that existing non-collapsing solutions in the AdS (in)stability problem persist to the zero-amplitude limit, opposing the conjecture by Dias, Horowitz, Marolf and Santos that predicts a shrinkage to measure-zero [1]. We also point out why the persistence of collapsing solutions is harder to prove, and how the recent interesting progress by Bizon, Maliborski and Rostoworowski is not there yet [2].

description: Vitamin D has been associated with decreased risk of several cancers. In experimental studies, vitamin D has been shown to inhibit cell proliferation and induce differentiation and apoptosis in normal and malignant breast cells. Using a population-based case-control study on Long Island, New York, we examined the association of breast cancer with plasma 25-hydroxyvitamin D (25-OHD) levels, a measure of vitamin D body stores. In-person interviews and blood specimens were obtained from 1,026 incident breast cancer cases diagnosed in 1996 to 1997 and 1,075 population-based controls. Plasma 25-OHD was measured in batched, archived specimens by Diasorin RIA. The mean (SD) plasma 25-OHD concentration was 27.1 (13.0) and 29.7 (15.1) ng/mL in the cases and controls, respectively (P < 0.0001). Plasma 25-OHD was inversely associated with breast cancer risk in a concentration-dependent fashion (Ptrend = 0.002). Compared with women with vitamin D deficiency (25-OHD, <20 ng/mL), levels above 40 ng/mL were associated with decreased breast cancer risk (odds ratio, 0.56; 95% confidence interval, 0.41–0.78). The reduction in risk was greater among postmenopausal women (odds ratio, 0.46; 95% confidence interval, 0.09–0.83), and the effect did not vary according to tumor hormone receptor status. In summary, these results add to a growing body of evidence that adequate vitamin D stores may prevent breast cancer development. Whereas circulating 25-OHD levels of >32 ng/mL are associated with normal bone mineral metabolism, our data suggest that the optimal level for breast cancer prevention is ≥40 ng/mL. Well-designed clinical trials are urgently needed to determine whether vitamin D supplementation is effective for breast cancer chemoprevention.

description: Helicobacter pylori infection promotes male-predominant gastric adenocarcinoma in humans. Estrogens reduce gastric cancer risk and previous studies demonstrated that prophylactic 17β-estradiol (E2) in INS-GAS mice decreases H. pylori-induced carcinogenesis. We examined the effect of E2 and Tamoxifen, on H. pylori-induced gastric cancer in male and female INS-GAS mice. After confirming robust gastric pathology at 16 weeks post-infection (WPI), mice were implanted with E2, Tamoxifen, both E2 and Tamoxifen, or placebo pellets for 12 weeks. At 28 WPI, gastric histopathology, gene expression and immune cell infiltration were evaluated, and serum inflammatory cytokines measured. After treatment, no gastric cancer was observed in H. pylori-infected males receiving E2 and/or Tamoxifen, while 40% of infected untreated males developed gastric cancer. E2, Tamoxifen and their combination significantly reduced gastric precancerous lesions in infected males compared to infected untreated males (P<0.001, 0.01 and 0.01, respectively). However, Tamoxifen did not alter female pathology regardless of infection status. Differentially expressed genes from males treated with E2 or Tamoxifen (n=363 and n=144, Q<0.05) associated highly with cancer and cellular movement, indicating overlapping pathways in the reduction of gastric lesions. E2 or Tamoxifen deregulated genes associated with metastasis (PLAUR and MMP10) and Wnt inhibition (FZD6 and SFRP2). Compared to controls, E2 decreased gastric mRNA (Q<0.05) and serum levels (P<0.05) of CXCL1, a neutrophil chemokine, leading to decreased neutrophil infiltration (P<0.01). Prevention of H. pylori-induced gastric cancer by E2 and Tamoxifen may be mediated by estrogen signaling and is associated with decreased CXCL1, decreased neutrophil counts and downregulation of oncogenic pathways.
Revisiting the Marton, Simpson, and Suddeth experimental confirmation of the Aharonov-Bohm effect

description: We perform an "archeological" study of one of the original experiments used as evidence for the static, time-independent Aharonov-Bohm effect. Since the experiment in question [L. Marton, J. A. Simpson, and J. A. Suddeth, Rev. Sci. Instr. 25, 1099 (1954)] involved a time varying magnetic field we show that there are problems with the explanation of this experiment as a confirmation of the static Aharonov-Bohm effect -- specifically the previous analysis ignored the electric field which arises in conjunction with a time-varying magnetic flux. We further argue that the results of this experiment do in fact conform exactly to the recent prediction [D. Singleton and E. Vagenas, Phys. Lett. B723, 241 (2013); J. MacDougall and D. Singleton, J. Math. Phys. 55, 042101 (2014)] of a cancellation between the magnetic and electric phase shifts for the time-dependent Aharonov-Bohm effect. To resolve this issue a new time-dependent Aharonov-Bohm experiment is called for.

description: Cold cations, electrons and anions are ubiquitous in space, participate in star formation chemistry and are relevant to studies on the origin of molecular biology homochirality. We report on a system to generate and trap these species in the laboratory. Laser ablation of a solid target (LiH) facing a sublimating Ne matrix generates cold electrons, anions, and cations. Axial energy distributions (of e$^-$, H$^\pm$ and Li$^\pm$) peaked at 0-25 meV are obtained in a Penning trap at 90 mT and 0.5 eV barrier. Anions can be guided and neutralized with low recoil energy by near-threshold photodetachment. An immediate prospect for this H$^-$ source is to load hydrogen atoms into the ALPHA antihydrogen trap at CERN towards direct spectroscopic comparison of both conjugated species beyond 13 significant figures. The production is potentially scalable and adaptable to different species including deuterium and tritium, relevant for neutrino mass and fusion research.
