Comments: Majewska et al. (2019, p. 625), working on Proschkinia spp. epizoic on sea turtles, described a new species P. torquata Bosak, Van de Vijver & Majewska, which they compared with P. complanatoides. They suggested that our Guam specimens might be a new species because they saw no widening of the central area (GU44Z-15: Fig. 90) and the internal fistula was not like P. complanatoides. However, Kim et al. (2020) studied Grunow’s specimens of P. complanata with SEM and showed a fistula matching ours, also matching in the presence of a flap over the external fistula opening (Figs 87, 88) and a raised rib on the raphe internally for some distance from the central nodule (Fig. 90). One short stria on the side with the fistula (Fig. 88), and a silica flap over the fistula opening; central striae on opposite sometimes further apart (Figs 87, 88 vs. 90). Comparing our specimens to P. torquata, the fistula has a similar series of spheres, and the external opening is also covered by a flap, but P. torquata has longitudinal silica strips over the central part of the valve face and the apices are rounded rather than acute. Kim et al. (2020, table 4) listed Guam specimens with P. complanata not P. complanatoides and their images of authentic (including type) material convince us that there are no differences that would warrant a new species. We have seen this species across Micronesia, and it seems so far to be the only species present. We remove P. complanatoides from the Guam flora.

description: In this paper we present a study of in-medium jet modifications performed with JEWEL and PYTHIA 6.4, focusing on the uncertainties related to variations of the perturbative scales and nuclear parton distribution functions (PDFs) and on the impact of the initial and crossover temperature variations of the medium. The simulations are compared to LHC data for the jet spectrum and the nuclear modification factor. We assess the interplay between the choice of nuclear PDFs and different medium parameters and study the impact of nuclear PDFs and the medium on the jet structure via the Lund plane.

description: Classical or quantum physical systems can simulate the Ising Hamiltonian for large-scale optimization and machine learning. However, devices such as quantum annealers and coherent Ising machines suffer an exponential drop in the probability of success in finite-size scaling. We show that by exploiting high dimensional embedding of the Ising Hamiltonian and subsequent dimensional annealing, the drop is counteracted by an exponential improvement in the performance. Our analysis relies on extensive statistics of the convergence dynamics by high-performance computing. We propose a realistic experimental implementation of the new annealing device by off-the-shelf coherent Ising machine technology. The hyperscaling heuristics can also be applied to other quantum or classical Ising machines by engineering nonlinear gain, loss, and non-local couplings.

description: In this essay Thayer-Bacon explores the issue of a chilly climate in higher education that is generated by some women, in particular White women, and the destructive behavior they bring to higher education that damages their programs, as well as their working relationships with colleagues and students. The author seeks to find ways to befriend women in higher education, her sisters of color as well as her White sisters. Thayer-Bacon's focus here is on White women. Her approach is to use stories from the field to illustrate problems that are analyzed, using a narrative style of philosophical argument

description: In quantum illumination, various detection schemes have been proposed for harnessing remaining quantum correlations of the entanglement-based resource state. To this date, the only successful implementation in the microwave domain relies on a specific mixing operation of the respective return and idler modes, followed by single-photon counting in one of the two mixer outputs. We investigate the performance of this scheme for realistic detection parameters in terms of detection efficiency, dark count probability, and photon number resolution. Furthermore, we take into account the second mixer output and investigate the advantage of correlated photon counting (CPC) for a varying thermal background and optimum post-processing weighting in CPC. We find that the requirements for photon number resolution in the two mixer outputs are highly asymmetric due to different associated photon number expectation values.

description: The purpose of this study was to determine the degree to which graduate students' perceptions of classroom community in their online and face-to-face classes differed based on gender. Students participating in the study were generally from urban, suburban, and rural school districts in Southwest Texas. All students (144) who were pursuing a master's degree in educational leadership using either face-to-face or online format in the fall semester, 2008 were emailed a survey. Of the 126 surveys returned (88%), 102 participants were selected for this study based on completion of data. Perceptions were measured using the Classroom Community Scale (CCS), which included three measures: Total classroom community, connectedness, and learning. Classroom community in both online and face-to-face classes was evaluated by students who were enrolled during the fall semester, 2008. It was found that after implementing classroom community elements, there were no statistically significant differences in the perceived total classroom community, connectedness, and learning of male and female students attending both face-to-face and online classes. The study also found that there were no statistically significant differences in the perceived total classroom community, connectedness, and learning of male and female students attending only online classes and for those attending only face-to-face classes. Findings suggest that by providing elements of a positive classroom community, university instructors can better meet the needs of male and female graduate students, thus eliminating any potential gender inequities in both face-to-face and online classes.

description: The purpose of the study was to investigate factors causing under representation of women in top educational management and leadership positions at the Ministry of Education headquarters in Kenya. Descriptive survey design, utilizing quantitative and qualitative approach was used in the study. Stratified random sampling was used to categorize the target population of 161 educational personnel by level of management and gender. Simple random sampling was then used to get a study sample of 76 officers. Questionnaire and interview guide were used to gather information from the respondents. Analysis of staff returns documents was done to get the numerical representation of the personnel by gender. Data were analyzed using descriptive statistics such as percentages, frequency distribution, mean scores, and standard deviations. The findings showed that 33.3 percent and 32.1 percent of top and middle management positions respectively were held by women. In terms of professional qualifications, 55 percent and 51.5 percent of M.Ed and B.Ed holders respectively, were women. Both male and female genders were rated "˜high' in possession of skills and personality characteristics the respondents considered important for top educational management and leadership positions. Organizational factors were the strongest barriers for women in ascending to top educational management and leadership positions. This was followed by socio-cultural and the least were individual factors. Strategies to improve the representation of women in top educational management and leadership therefore focused on the girl child in school, women themselves, society, government policies, the Education Act and the country's constitution

description: We study the soft theorems for photons and gravitons at finite temperatures using the thermofield dynamics approach. The soft factors lose universality at finite temperatures as the soft amplitudes depend on the nature (or spin) of the particles participating in the scattering processes. However, at low temperatures, a universal behaviour is observed in the cross-section of the soft processes. Further, we obtain the thermal contribution to the electromagnetic and gravitational memory effects and show that they are related to the soft factors consistently. The expected zero temperature results are obtained from the soft factors and memories. The thermal effects in soft theorems and memories seem to be sensitive to the spin of the particles involved in scattering.

Year: 2017

description: Women continue to struggle to reach parity in the workplace, constantly hitting their heads on the glass ceiling. The inability to break through this barrier may lead women to develop covert actions to create an advantage over their competition. The existing literature on the relationships of women and men in the workplace provides some insight to the struggles that occur when one gender could be considered a professional minority. In addition, some researchers have studied the working relationships of women in the business environment, but there is a deficiency in the literature of the working relationships among women in academic organizations. The purpose of our study was to explore the challenges of female relationships in the community college workplace, as women continue to dominate these institutions as both employees and students. A psychodynamic perspective was used as the theoretical framework for the study. We sought to assess the perceptions of female professional staff in public community colleges of how women supported the career advancement of their female peers, as well as how their supervisors and departments supported the professional development of potential female leaders. The results of the mixed method study identified two areas of limitations for women within community college environments: interpersonal and institutional cultural. The results of the quantitative analysis identified that a majority of females felt their peers were supportive of the career advancement of their female colleagues. The qualitative results of the study painted a different picture, indicating that women may use covert actions to compete with and hold back their female colleagues.

description: I will begin by reviewing the evidence for Dark Matter in the Universe, as well as the candidates for dark matter. At most 20% of the dark matter in galaxies can be in the form of MACHOs (Massive Compact Halo Objects); the remainder appears to be some unknown exotic component. The most sensible candidates from the point of view of particle physics are axions and WIMPs (Weakly Interacting Massive Particles), where WIMPs may be supersymmetric particles. Three recent claims of possible detection of WIMP dark matter are tantalizing and will be discussed: the DAMA annual modulation, the HEAT positron excess, and gamma-rays from the Galactic Center. In addition, I will discuss the dependence of signals in detectors on the mass distribution in the Galactic Halo. In particular, the Sagittarius stream can be a smoking gun for WIMP detection.

Sample: GU26A
Dimensions: Length 5.5–9.2 µm, width 2.3 µm, striae 15 in 10 µm
Diagnostics: Small, clavate (heteropolar), with a clear pore field at one pole, simple, stick-like spines arising from areolae, whereas in S. rhombica there are “accessory” spines flanking the larger central spines (C. Li et al. 2018).
Comments: Many small Fragilariaceae have been studied recently, incorporating much debate on generic boundaries. Serratifera Ashworth, Chunlian Li & Witkowski (in C. Li et al. 2016) was established largely on molecular grounds and emended on morphological grounds by the same authors (in C. Li et al. 2018). Morales et al. (2019: 274) argued against the new genus and for inclusion of its species in the older genus Pseudostaurosira D.M.Williams & Round. Witkowski did not accept the argument (personal communication during ms. preparation), so we have presented this and the next species under their original names. Morales et al. transferred them to Pseudostaurosira andersonii (S.Sato, Chunlian Li & Witkowski) E.A.Morales, Novais & C.E.Wetzel, and P. rhombica (S.Sato, Chunlian Li & Witkowski) E.A.Morales, Novais & C.E.Wetzel, respectively. The senior author cannot contribute to this debate. All small Fragillariaceae are rare in our Guam samples to date, probably because the frustules are washing in from their primary habitats (mostly sediments and biofilms).

description: To evaluate the diagnostic value of Ultrasound Computer Tomography (USCT), the imaging results have to be correlated with conventional breast imaging techniques. This is challenging due to different patient positioning in the modalities with nonlinear deformations of the breast tissue. We have developed a patient-specific image registration method, which simulates different breast positionings in both X-ray mammography and Magnetic Resonance Imaging (MRI) through biomechanical modelling. An average registration error below 5 and 17 mm for MRI to USCT and USCT to mammography registration, respectively, allowed us to evaluate the diagnostic performance of USCT. It was shown that regions of high sound speed corresponded well with the tumour position indicated from the MRI contrast kinetic map. Moreover, the quantitative analysis of sound speed and attenuation values with respect to the segmented mammograms revealed that sound speed gives a better distinction between breast tissue, whereas their combined information further improves the classification. Although the results are based on a preliminary study, the promising outcome points that the registration could assist radiologists in comparing the USCT with both MRI and X-ray mammography.

description: We report the temperature ($T$) dependence of ferromagnetic Bragg peak intensities and dc magnetization of the superconducting ferromagnet UGe2 under pressure ($P$). We have found that the low-$T$ behavior of the uniform magnetization can be explained by a conventional Stoner model. A functional analysis of the data produces the following results: The ferromagnetic state below a critical pressure can be understood as the perfectly polarized state, in which heavy quasiparticles occupy only majority spin bands. A Stoner gap $Δ(P)$ decreases monotonically with increasing pressure and increases linearly with magnetic field. We show that the present analysis based on the Stoner model is justified by a consistency check, i.e., comparison of density of states at the Fermi energy deduced from the analysis with observed electronic specific heat coeffieients. We also argue the influence of the ferromagnetism on the superconductivity.

description: Leadership has frequently employed sport stories and metaphor to exemplify attributes and attitudes that leaders should embrace in order to succeed. Competitive sport entered educational contexts in elite British boarding schools for the very purpose of providing training for future political and corporate leaders. As such, the paradigms for leadership reproduced through sport metaphors have held on to traditional, masculine views of leadership. Yet, these paradigms are outdated and do not fit the values embraced by twenty-first century leadership concepts. New sport metaphors are needed. This article begins the task of shaping new perspectives about leadership from the sport world. Specifically, attitudes and practices of high-performance female ultrarunners provide prime examples of the new lessons for leadership, focusing on empathy as one of the

description: Quantum nonlocality offers a secure way to produce random numbers: their unpredictability is intrinsic and can be certified just by observing the statistic of the measurement outcomes, without assumptions on how they are produced. To do this, entangled pairs are generated and measured to violate a Bell inequality with the outcome statistics. However, after a projective quantum measurement, entanglement is entirely destroyed and cannot be used again. This fact poses an upper bound to the number of random numbers that can be produced from each quantum state when projective measurements are employed. Instead, by using weak measurements, some entanglement can be maintained and reutilized, and a sequence of weak measurements can extract an unbounded amount of randomness from a single state as predicted in Phys. Rev. A 95, 020102(R) (2017). We study the feasibility of these weak measurements, analyze the robustness to imperfections in the quantum state they are applied to, and then test them using an optical setup based on polarization-entangled photon pairs. We show that the weak measurements are realizable, but can improve the performance of randomness generation only in close-to-ideal conditions.

description: We extend previous calculations of the zero temperature superfluid fraction $f_s$ (SFF) {\it vs} localization, from the fcc lattice to the experimentally realized (for solid $^4$He) hcp and bcc lattices. The superfluid velocity is assumed to be a one-body function, and dependent only on the local density, taken to be a sum over sites of gaussians of width $σ$. Localization is defined as $σ/d$, with $d$ the nearest-neighbor distance. As expected, for fcc and bcc lattices the superfluid density tensor is proportional to the unit tensor. To numerical accuracy of three-places (but no more), the hcp superfluid density tensor is proportional to the unit tensor. This implies that a larger spread in data on $f_s$, if measured on pure crystals, is unlikely to be due to crystal orientation. In addition, to three decimal places (but no more) the curves of $f_s$ {\it vs} $σ/d$ are the same for both the hcp and fcc cases. An expected value for the localization gives an $f_{s}$ in reasonable agreement with experiment. The bcc lattice has a similar curve of $f_s$ {\it vs} $σ/d$, but is generally smaller because the lattice is more dilute.

Comments: Similar to T. plana (W.Smith) Pelletan [Peragallo & Peragallo 1897 –1908 p. 270, pl. 70, fig. 18; Sims 1996, pl. 194, fig 2; Lopez-Fuerte et al. 2010, pl. 38, fig. 1 (all as Nitzschia plana W.Smith)], but that has 19–20 striae in 10 µm. Not clear from literature that either species has external costae. Montgomery (1978) has two images (pl. 160C and 161D) labeled as “ Nitzschia jelinecki ” but neither has external costae. Peragallo & Peragallo (1897 –1908) commented that they had only seen it in “exotic” samples, the one figured from Java; type was from the Nicobar Islands. This species needs much more study before we can say whether the Guam specimens belong in it or elsewhere.

Dimensions: Length 25–28 µm, width 17–20 µm; striae 9 in 10 µm (RV), 7–8 in 10 µm (SV)
Samples: GU52X-5, GU52N-7, GU52P-3
Diagnostics: The raised apices of the RV are diagnostic of the genus in LM, the large circular central area diagnostic of the species in contrast to V. florifera Riaux-Gobin, O.E.Romero, Compère & A.Y.Al-Handel (2011), which has a broad fascia.
Comments: These specimens are in the lower end of the size range compared to most literature (see van de Vijver et al. 2009, table 1). There are two troubling differences between our specimens and those shown in the recent literature. First, comparison of the internal SV in our Fig. 112 with figs 16, 19 in van de Vijver et al. (2009) and similar images in Witkowski et al. (2000) and Riaux-Gobin et al. (2011) shows absence in our specimen of the elliptical opening and slit in the marginal ridges; this may be significant even though it was also absent in some specimens by van de Vijver et al. (2009, fig.20). Secondly, Van de Vijver et al. (2009: 271, fig. 27, arrow) show small costae extending from the RV margin into the first row of areolae, a feature clearly absent from the external RV shown in Fig. 113. This is yet another genus with strong potential for additional species to be found.

Iron Sharpens Iron: Exploring the Experiences of Female College Student Leaders
Creators: name: Haber, Paige
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: This qualitative study explored a small sample of female college students' perceptions of their experiences in leadership positions. Specifically the researcher examined the women's leadership styles and the factors that influenced how they lead. Additionally, the researcher focused on how gender may relate to the women's experiences. Basic interpretive and descriptive qualitative research methods were employed. Data were collected through in-depth individual interviews, a focus group, and participant journals. Participants included four female students at a medium-sized, religiously affiliated private university who held significant leadership roles in student organizations. Results revealed that the participants employed either a relationship-oriented, task-oriented, or hybrid approach to leading. Additional themes emerged around influences on the women's approaches to leadership, with particular emphasis on the role of the larger environment in impacting students' leadership behaviors, and the role gender plays in their leadership experiences. This study can provide insight into the landscape of young women's leadership today and help begin to fill the research gap that currently exists about college student women holding formal leadership roles and how to support these leaders.

ALMA 300 pc resolution imaging of a z=6.79 quasar: no evidence for supermassive black hole influence on the [C II] kinematics

description: We present Atacama Large Millimeter/submillimeter Array (ALMA) [C II] 158 $μ\rm{m}$ and dust continuum observations of the $z=6.79$ quasar J0109--3047 at a resolution of $0."045$ ($\sim$300 pc). The dust and [C II] emission are enclosed within a $\sim 500\, \rm{pc}$ radius, with the central beam ($r<144\ \rm{pc}$) accounting for $\sim$25\% (8\%) of the total continuum ([C II]) emission. The far--infrared luminosity density increases radially from $\sim$5 $\times 10^{11} L_\odot\ \rm{kpc}^{-2}$ to a central value of $\sim$70 $\times 10^{11} L_\odot\ \rm{kpc}^{-2}$ (SFRD $\sim$50-700 $M_\odot\ \rm{yr}^{-1}\ \rm{kpc}^{-2}$). The [C II] kinematics are dispersion-dominated with a constant velocity dispersion of $137 \pm 6 \,\rm{km\ s}^{-1}$. The constant dispersion implies that the underlying mass distribution is not centrally peaked, consistent with the expectations of a flat gas mass profile. The lack of an upturn in velocity dispersion within the central beam is inconsistent with a black hole mass greater than $M_{\rm{BH}}<6.5\times 10^{8}\ M_\odot\ (2σ$ level), unless highly fine-tuned changes in the ISM properties conspire to produce a decrease of the gas mass in the central beam comparable to the black hole mass. Our observations therefore imply either that a) the black hole is less massive than previously measured or b) the central peak of the far-infrared and [C II] emission are not tracing the location of the black hole, as suggested by the tentative offset between the near-infrared position of the quasar and the ALMA continuum emission.

American Women and the Gender Pay Gap: A Changing Demographic or the Same Old Song
Creators: name: Gundersen, David E.
Publisher: name: Advancing Women in Leadership Journal
Year: 2017

description: Women have made great strides in education and career opportunity selections since the passage of the Equal Pay Act in 1963. Despite these many gains, female remuneration has not kept pace. The gender pay-gap continues to exist with serious consequences for women and the families that depend on their earnings. The gap is presented and framed historically and legislation is presented that has influenced women's pay. A variety of explanations for why the gap continues are explored and debunked. The effects of the pay gap are presented and analyzed with policy initiatives offered underscoring possible solutions.

description: We report the observation of the resonant excitation of edge photocurrents in bilayer graphene subjected to terahertz radiation and a magnetic field. The resonantly excited edge photocurrent is observed for both inter-band (at low carrier densities) and intra-band (at high densities) transitions between Landau levels (LL). While the intra-band LL transitions can be traced to the classical cyclotron resonance (CR) and produce strong resonant features, the inter-band-LL resonances have quantum nature and lead to the weaker features in the measured photocurrent spectra. The magnitude and polarization properties of the observed features agree with the semiclassical theory of the intra-band edge photogalvanic effect, including its Shubnikov-de-Haas oscillations at low temperatures.

description: We derive a $ΛΛ$ potential from a chiral constituent quark model that has been successful in describing one, two and three nonstrange baryon systems. The resulting interaction at low energy is attractive at all distances due to the $σ$ exchange term. The attraction allows for a slightly bound state just below the $ΛΛ$ threshold. No short-range repulsive core is found. We extract the diquark-diquark contribution that turns out to be the most attractive and probable at small distances. At large distances the asymptotic behavior of the $ΛΛ$ interaction provides a prediction for the $σΛΛ$ coupling constant.

Determining the range of validity of quasar X-ray and UV flux measurements for constraining cosmological model parameters

description: We use six different cosmological models to study the recently-released compilation of X-ray and UV flux measurements of 2038 quasars (QSOs) which span the redshift range $0.009 \leq z \leq 7.5413$. We find, for the full QSO data set, that the parameters of the X-ray and UV luminosities $L_X-L_{UV}$ relation used to standardized these QSOs depend on the cosmological model used to determine these parameters, i.e, it appears that the full QSO data set include QSOs that are not standardized and so cannot be used for the purpose of constraining cosmological parameters. Subsets of the QSO data, restricted to redshifts $z \lesssim 1.5-1.7$ obey the $L_X-L_{UV}$ relation in a cosmological-model-independent manner, and so can be used to constrain cosmological parameters. The cosmological constraints from these lower-$z$, smaller QSO data subsets are mostly consistent with, but significantly weaker than, those that follow from baryon acoustic oscillation and Hubble parameter measurements.

description: The growing population of man-made objects with the build up of mega-constellations not only increases the potential danger to all space vehicles and in-space infrastructures (including space observatories), but above all poses a serious threat to astronomy and dark skies. Monitoring of this population requires precise satellite characterization, which is is a challenging task that involves analyzing observational data such as position, velocity, and light curves using optimization methods. In this study, we propose and analyze the application of two optimization procedures to determine the parameters associated with the dynamics of a satellite: one based on the Theory of Functional Connections (TFC) and another one based on the Nelder-Mead heuristic optimization algorithm. The TFC performs linear functional interpolation to embed the constraints of the problem into a functional. In this paper, we propose to use this functional to analytically embed the observational data of a satellite into its equations of dynamics. After that, any solution will always satisfy the observational data. The second procedure proposed in this research takes advantage of the Nealder-Mead algorithm, that does not require the gradient of the objective function, as alternative solution. The accuracy, efficiency, and dependency on the initial guess of each method is investigated, analyzed, and compared for several dynamical models. These methods can be used to obtain the physical parameters of a satellite from available observational data and for space debris characterization contributing to follow-up monitoring activities in space and astronomical observatories.
