description: Mecyclothorax Sharp, 1903
[For complete generic synonymy, see Liebherr and Marris 2009.]
 Diagnosis. Species of the genus Mecyclothorax can be diagnosed within Psydrini by the presence of attenuate, setose male parameres and an aedeagal median lobe that is closed basally (Moore 1963). The right paramere bears a series of setae along its ventral surface and the left paramere has two to five setae at its apex (Moore 1984). The ligula of the labium is broadly truncate and bisetose apically, the paraglossae are free and elongate, and the penultimate labial palpomeres are bisetose on their anterior margin. There can be from 0–5 dorsal elytral setae, and the 7th elytral interval may be carinate or flat apically (Liebherr and Marris 2009). All Hawaiian species are brachypterous, with the flight wing vestigium varying from an elongate micropterous strap that extends past the posterior margin of the metathorax— e.g., M. montivagus (Blackburn) of Maui—to a very short vestigial flap that does not extend past the metathoracic hind margin. In association with the brachypterous condition, all Hawaiian species are characterized by a foreshortened metathorax, evidenced by a short metepisternum.

description: Background: Among those most vulnerable to the negative effects of COVID-19 mitigation measures, such as social distancing, were individuals with physical (e.g. amputation, cancer) and mental (e.g. post-traumatic stress) illnesses and injuries. Purpose: This study examined the psychosocial impact of COVID-19 on military personnel with physical and mental illnesses and injuries participating (i.e. competitors) or seeking to participate (i.e. non-competitors) in a competitive parasport recovery program. Methods: In May, August, and November 2020, measures assessing the psychosocial impact of COVID-19 were added to English-language surveys as part of international longitudinal research examining the impact of parasport for military personnel post-injury and illness. Data were analyzed using descriptive analyses, repeated measures ANOVA, and content analysis. Results: Participants [n=135; competitors n=56] represented 5 countries. Some participants coped with COVID-19 by engaging in positive health behaviors (e.g. seeking connection, relaxing), while others coped with negative health behaviors (e.g. drinking, smoking, eating higher fat or sugary foods). Half of participants experienced delays or cancellations in mental health appointments. Non-competitors demonstrated significantly more perceived stress than competitors (p

description: We study the implications of a combined analysis of cosmic standard candles and standard rulers on the viability of cosmological models beyond the cosmological concordance model. To this end, we employ well-established data in the form of the joint light-curve analysis supernova compilation, baryon acoustic oscillations, and cosmic microwave background data on the one hand, and a recently proposed set of quasars as objects of known brightness on the other hand. The advantage of including the latter is that they extend the local distance measures to redshifts which have previously been out of reach and we investigate how this allows one to test cosmologies beyond $Λ$CDM. While there exist various studies on parametric extensions of $Λ$CDM, we present here a comparative study of both parametric and fundamental extensions of the standard cosmology. In order to keep the scope of this manuscript contained, we focus on two particular modifications: One is the consistent theory of two interacting spin-2 objects, so-called bigravity, and the other conformal gravity, a theory of gravity that has no knowledge of fundamental length scales. The former of the two constitutes a veritable extension of General Relativity, given that it adds to the metric tensor of gravity a second dynamical tensor field. The resulting dynamics have been proposed as a self-accelerating cosmology. Conformal gravity on the other hand is a much more drastic change of the underlying gravitational theory. Its ignorance towards fundamental length scales offers a completely different approach to the origin of late time acceleration. In this sense, both models offer - in one way or another - an explanation for the dark energy problem. We perform a combined cosmological fit which provides strong constraints on these extensions. We also briefly comment on the implications of the long-standing $H_0$-tension.

Mecyclothorax vitreus

description: Mecyclothorax vitreus species-group
 Diagnosis. This group can be distinguished by: 1) glabrous pronotum with very narrow, posteriorly sinuate lateral margins; 2) presence of only the posterior supraorbital seta, the anterior seta being absent; 3) well-developed but not hemispherically convex eyes; 4) the presence of striae 1–2 to 1–5 on the elytral disc, but only the sutural stria 1 well-developed at elytral apex; and 5) reduced microsculpture, the dorsal surface glossy. Britton (1948) diagnosed the group so that his three included species lacked elytral microsculpture, however, some individuals of M. perkinsianus (Sharp) exhibit transverse mesh microsculpture over portions of the elytra. Mecyclothorax flavipes, new species deviates from Britton’s diagnosis by having shallow transverse-mesh microsculpture over the entire elytra, though the surface appears glossy up to 80 3 magnification. However, among all Hawaiian Mecyclothorax, M. flavipes agrees only with the species placed by Britton in his M. vitreus species group in the combination of glabrous pronotum and absence of the anterior supraorbital seta. As these are assuredly synapomorphies relative to the Hawaiian Mecyclothorax ground-plan, the species group diagnosis is broadened to include M. flavipes. In addition to this single Lanai species, the species group also includes M. deverilli (Blackburn) of Hawaii Island, and two described species from East Maui, i.e., M. perkinsianus (Sharp) and M. vitreus Britton from Haleakala Volcano (Britton 1948). Contrary to Liebherr (2008 b), the group is not present on Molokai.

description: The topological properties of a material's electronic structure are encoded in its Berry curvature, a quantity which is intimately related to the transverse electrical conductivity. In transition metal dichalcogenides with broken inversion symmetry, the nonzero Berry curvature results in a valley Hall effect. In this paper we identify a previously unrecognized consequence of Berry curvature in these materials: an electric field-induced change in the electrons' charge density orientation. We use first principles calculations to show that measurements of the electric field-induced change in the charge density or local density of states in MoS$_2$ can be used to measure its energy-dependent valley and orbital Hall conductivity.

description: Gene regulatory network of lambda phage is one the best studied model systems in molecular biology. More 50 years of experimental study has provided a tremendous amount of data at all levels: physics, chemistry, DNA, protein, and function. However, its stability and robustness for both wild type and mutants has been a notorious theoretical/mathematical problem. In this paper we report our successful calculation on the properties of this gene regulatory network. We believe it is of its first kind. Our success is of course built upon numerous previous theoretical attempts, but following 3 features make our modeling uniqu: 1) A new modeling method particular suitable for stability and robustness study; 2) Paying a close attention to the well-known difference of in vivo and in vitro; 3) Allowing more important role for noise and stochastic effect to play. The last two points have been discussed by two of us (Ao and Yin, cond-mat/0307747), which we believe would be enough to make some of previous theoretical attempts successful, too. We hope the present work would stimulate a further interest in the emerging field of gene regulatory network.

 Diagnosis. This group contains species with elytral striae 1–5 developed on the disc, but striae progressively reduced laterally. Apically, the second elytral stria is as deep to only slightly shallower than the sutural stria, distinguishing these species from similar appearing taxa of the M. palustris group. In addition, the M. ovipennis group is diagnosed by: 1) pronotum basally sinuate with evident hind angles and moderately broad lateral marginal depressions; 2) pronotum either with lateral seta each side, or both lateral and basal setae; 3) eyes well-developed but not hemispherical and highly convex; and 4) dorsal elytral setal position inconspicuous, setae not situated in deep foveae. In addition to the single Lanai species, this group includes nine species from Molokai (Liebherr 2006 b), eight described species on Maui (Britton 1948), and four species from Hawaii Island (Liebherr 2008 b).

description: Ecosystems face multiple, potentially interacting, anthropogenic pressures that can modify biodiversity and ecosystem functioning. Using a bryophyte–microarthropod microecosystem we tested the combined effects of habitat loss, episodic heat-shocks and an introduced non-native apex predator on ecosystem function (chlorophyll fluorescence as an indicator of photosystem II function) and microarthropod communities (abundance and body size). The photosynthetic function was degraded by the sequence of heat-shock episodes, but unaffected by microecosystem patch size or top-down pressure from the introduced predator. In small microecosystem patches without the non-native predator, Acari abundance decreased with heat-shock frequency, while Collembola abundance increased. These trends disappeared in larger microecosystem patches or when predators were introduced, although Acari abundance was lower in large patches that underwent heat-shocks and were exposed to the predator. Mean assemblage body length (Collembola) was reduced independently in small microecosystem patches and with greater heat-shock frequency. Our experimental simulation of episodic heat waves, habitat loss and non-native predation pressure in microecosystems produced evidence of individual and potentially synergistic and antagonistic effects on ecosystem function and microarthropod communities. Such complex outcomes of interactions between multiple stressors need to be considered when assessing anthropogenic risks for biota and ecosystem functioning.

description: Image steganography refers to the process of hiding information inside images. Steganalysis is the process of detecting a steganographic image. We introduce a steganalysis approach that uses an ensemble color space model to obtain a weighted concatenated feature activation map. The concatenated map helps to obtain certain features explicit to each color space. We use a levy-flight grey wolf optimization strategy to reduce the number of features selected in the map. We then use these features to classify the image into one of two classes: whether the given image has secret information stored or not. Extensive experiments have been done on a large scale dataset extracted from the Bossbase dataset. Also, we show that the model can be transferred to different datasets and perform extensive experiments on a mixture of datasets. Our results show that the proposed approach outperforms the recent state of the art deep learning steganalytical approaches by 2.32 percent on average for 0.2 bits per channel (bpc) and 1.87 percent on average for 0.4 bpc.

description: Background: Parasport is a popular method for promoting recovery among military personnel with illness and injury. However, despite powerful anecdotal, cross-sectional, and short-term findings revealing benefits to military parasport programming, researchers have yet to determine whether benefits are maintained in the long-term, particularly in comparison to military personnel who do not participate in competitive parasport events. Purpose: To explore the long-term impact of parasport through the Invictus Games, an international parasport competition for military personnel. In particular, to compare physical and psychosocial health outcomes between Sydney 2018 Invictus Games competitors and individuals not selected for the Games. Methods: The current analysis focused on English and French-speaking military personnel from Australia, Canada, New Zealand, the United Kingdom, and the United States of America. Seventy competitors and 145 non-competitors, experiencing physical (e.g. amputation, spinal cord injury, traumatic brain injury) and/or psychological (e.g. depression, anxiety, post-traumatic stress) illnesses and injuries, completed surveys at six time-points assessing affect, psychological well-being, life satisfaction, post-traumatic growth, and physical health. The first survey was distributed 3 months before the Sydney 2018 Invictus Games and the final survey was distributed one year after the Games. Repeated measures ANCOVA were used to compare outcomes between competitors and non-competitors. Results: Competitors demonstrated significantly better affect, psychological well-being, life satisfaction, post-traumatic growth, and general health than non-competitors (ps < .05). However, there was no difference between groups on measures of bodily pain and pain interference (ps > .05). Conclusions: Findings suggest that parasport may result in positive long-term physical and psychosocial health outcomes. However, the lack of difference between groups on pain-related outcomes needs to be further explored, particularly as pain is a common side effect of the illnesses and injuries experienced by Invictus Games competitors. Future research will also examine the impact across additional Invictus nations, as well as earlier in training to determine when differences initially emerge between groups. Funding: Study completed in partnership with the Invictus Games Foundation, with funding provided by Forces in Mind Trust, a £35 million funding scheme run by the Trust using an endowment awarded by the Big Lottery Fund.

By using appropriate decay conditions for the existing propagating modes in the near-horizon of a stationary black hole, we obtain the charges generating the asymptotic symmetries. We show that the charges are integrable and the (modified) algebras among the asymptotic generators are closed for the certain choice of central extensions.

description: Bembidion ignicola Blackburn
 Distribution. On Lanai, this species has been collected only once near Lanaihale (Fig. 5D). It is recorded from all of the other Hawaiian high islands (Liebherr 2008 a). The specimen is brachypterous, suggesting long-term persistence of a population of this species on the island (Southwood 1977).
 Habitat. The single Lanai specimen was collected during daytime by beating foliage of a small ohia tree situated in open forest with uluhe fern understory. The ohia had a thin covering of lichens and some moss clumps. Cibotium Kaulfuss tree ferns and other ohia trees were beaten in the vicinity, producing specimens of B. depressa and M. filipes.
 Tribe Platynini
 Diagnosis. Diagnosable within the Hawaiian fauna by: 1) conjunct mesocoxal cavities; 2) glabrous mandibular scrobe; 3) mesally glabrous pronotal disc and third visible abdominal ventrite; and 4) lateral elytral margins bearing only lateral elytral setae situated in depressed foveae, without a pelage of fine microsetae covering the areas between the lateral setae (Liebherr and Zimmerman 2000). The five species of Blackburnia plus the non-native platynine species M. buchanani that are recorded from Lanai are taxonomically treated by Liebherr and Zimmerman (2000).

description: We consider the evolution of a spherically expanding plasma cloud, where there is continuous injection of non-thermal electrons. We compute the time dependent electron distribution and resultant photon spectra taking into account synchrotron, adiabatic and inverse Compton cooling. This model is different from previous works where, instead of a continuous injection of particles, a short injection period was assumed. We apply this model to the radio/optical knots in the large scale jets of AGN, detected in X-rays by {\it Chandra} and find that the overall broadband spectral features can be reproduced. It is shown that for some sources, constraints on the X-ray spectral index (by a longer {\it Chandra} observation) will be able to differentiate between the different models. This in turn will put a strong constraint on the acceleration mechanism active in these sources.

description: Keeping track of and managing Self-Admitted Technical Debts (SATDs) are important to maintaining a healthy software project. This requires much time and effort from human experts to identify the SATDs manually. The current automated solutions do not have satisfactory precision and recall in identifying SATDs to fully automate the process. To solve the above problems, we propose a two-step framework called Jitterbug for identifying SATDs. Jitterbug first identifies the "easy to find" SATDs automatically with close to 100% precision using a novel pattern recognition technique. Subsequently, machine learning techniques are applied to assist human experts in manually identifying the remaining "hard to find" SATDs with reduced human effort. Our simulation studies on ten software projects show that Jitterbug can identify SATDs more efficiently (with less human effort) than the prior state-of-the-art methods.

description: Cosmological N-body simulations predict that dark matter halos should have a universal shape characterized by a steep, cuspy inner profile. Here we report on a spectroscopic study of six clusters each containing a dominant brightest cluster galaxy (BCG) with nearby gravitational arcs. Three clusters have both radial and tangential gravitational arcs, whereas the other three display only tangential arcs. We analyze stellar velocity dispersion data for the BCGs in conjunction with the arc redshifts and lens models to constrain the dark and baryonic mass profiles jointly. For those clusters with radial gravitational arcs we were able to measure precisely the inner slope of the dark matter halo and compare it with that predicted from CDM simulations.

description: Machine learning models provide statistically impressive results which might be individually unreliable. To provide reliability, we propose an Epistemic Classifier (EC) that can provide justification of its belief using support from the training dataset as well as quality of reconstruction. Our approach is based on modified variational auto-encoders that can identify a semantically meaningful low-dimensional space where perceptually similar instances are close in $\ell_2$-distance too. Our results demonstrate improved reliability of predictions and robust identification of samples with adversarial attacks as compared to baseline of softmax-based thresholding.

Photosynthesis and Transpiration Rate as Indicator of Carbon Sequestration and the Effect of Three Hormones : Jasmonic Acid, Ethylene and Cytokinin on Leaf Senescence of an Evergreen Thuja plicata (Western Red Cedar)
Creators: name: Ghiam, Mona

description: The objective of this study was to measure photosynthesis and transpiration rate of Thuja plicata as indicators of carbon sequestration through environmental and seasonal changes. Photosynthesis and transpiration rates were measured automatically by CI-340 Handheld photosynthesis machine from November 10, 2017 to March 28, 2018. Our hypothesis matched our results that both photosynthesis and transpiration rates decrease during winter compared to fall and spring. Photosynthesis and transpiration rates were highest in the beginning of November and they both dropped by about 20% in winter, reaching lowest in middle of January. Another objective of this study was to observe whether the presence of exogenous hormones ethylene (CEPA), cytokinin (BAP) and jasmonic acid (JA) promotes leaf senescence in the evergreen Thuja plicata. 5mL of 1uM, 10uM, and 100uM concentration stock solutions of each hormone and 0.7-0.8 grams of leaflets were added to a total of 40 petri dishes; samples were taken from each plate once a week for up to 6 weeks. We hypothesized that JA and CEPA promote leaf senescence and BAP prevents leaf senescence. It was observed that JA was the first hormone to cause leaf senescence and CEPA was the second hormone that caused leaf senescence, and in both cases chlorophyll and proteins were degraded as indication of leaf senescence; BAP prevented leaf senescence in the first 3 weeks but at the end of week 6, 100uM BAP induced leaf senescence.

description: Given a graph $G=(V,E)$, the longest induced path problem asks for a maximum cardinality node subset $W\subseteq V$ such that the graph induced by $W$ is a path. It is a long established problem with applications, e.g., in network analysis. We propose novel integer linear programming (ILP) formulations for the problem and discuss efficient implementations thereof. Comparing them with known formulations from literature, we prove that they are beneficial in theory, yielding stronger relaxations. Moreover, our experiments show their practical superiority.

Wrapped D-Branes as BPS Monopoles: The Moduli Space Perspective
Creators: name: Barrett, Jessica K.

Year: 2003

description: We study the four dimensional effective action of a system of D6-branes wrapped on the K3 manifold times a torus, allowing the volume of the internal manifolds to remain dynamical. An unwrapped brane is at best a Dirac monopole of the dual R-R sector field to which it couples. After wrapping, a brane is expected to behave as a BPS monopole, where the Higgs vacuum expectation value is set by the size of the K3. We determine the moduli space of an arbitrary number of these wrapped branes by introducing a time dependent perturbation of the static solution, and expanding the supergravity equations of motion to determine the dynamics of this perturbation, in the low velocity limit. The result is the hyper-Kahler generalisation of the Euclidean Taub-NUT metric presented by Gibbons and Manton. We note that our results also pertain to the behavior of bound states of Kaluza-Klein monopoles and wrapped NS5-branes in the T^4 compactified heterotic string.

Blackburnia lanaiensis

description: Blackburnia (Colpocaccus) lanaiensis (Sharp)
 Distribution. Known only from two historical collectors, Perkins (1894) and Giffard (1908) (Fig. 5E). The Fauna Hawaiiensis specimens collected by Perkins were in his lots (corresponding data in parentheses, Anonymous N.D.): 80 (‘‘Lanai 2.000 ft I ’94’’), 83 (‘‘Lanai, behind Koele, about 2.000 ft. ’94’’), 86 (Lanai, above 2.000 ft. I. ’94’’), 87 (Lanai, behind Koele, II. ’94) and 94 (‘‘Lanai nr. Koele. I. ’94’’). Koele was the site of the main house on Lanai, and ‘‘behind Koele’’ corresponds to the large valley that opens to the northeast; Kaiholena Gulch. This valley extends southeast to head just north of Puu Alii at 865 m elevation, suggesting Perkins collected his B. lanaiensis specimens in this valley near 600 m elevation on the way to and from the high forest. This interpretation is bolstered by definitively labeled specimens of native Delphacidae collected by Munro in Kaiholena Gulch at 600 m (Muir 1917). Brown (1900) indicates a stream in the base of this valley that is marked upward to approximately 550 m. Giffard (1908) collected his single B. lanaiensis specimen ‘‘from under stones,’’ labeling the specimen ‘‘20009 Kaua Val.’’ (BPBM), interpreted as the present-day Kahua Gulch northwest of Koele at 610 m. Brown’s (1900) map of Lanai indicates a road along the northern rim of Kahua Gulch that would have provided direct access to the head of this valley from Giffard’s accommodations at the Koele Ranch house.
 Habitat. The known records on Lanai place this species as a terrestrial inhabitant of stream margins. The species is extant on Molokai and Maui where it occurs in riparian or streamside habitats (Liebherr and Zimmerman 2000). The head of Kahua Valley is currently placed within the dry forest community (Fig. 1), whereas Kaiholena Gulch lies within the mesic forest community.

description: We construct matter-coupled N=2 supergravity in five dimensions, using the superconformal approach. For the matter sector we take an arbitrary number of vector-, tensor- and hyper-multiplets. By allowing off-diagonal vector-tensor couplings we find more general results than currently known in the literature. Our results provide the appropriate starting point for a systematic search for BPS solutions, and for applications of M-theory compactifications on Calabi-Yau manifolds with fluxes.

Determination of theta_{23} in Long-Baseline Neutrino Oscillation Experiments with Three-Flavor Mixing Effects

description: We examine accuracy of theta_{23} determination in future long-baseline (LBL) nu_{mu} disappearance experiments in the three-flavor mixing scheme of neutrinos. Despite that the error of sin^2{2theta_{23}} is indeed a few % level at around the maximal mixing, we show that the error of physics variable s^2_{23} is large, delta(s^2_{23})/s^2_{23} \simeq 10-20%, depending upon regions of theta_{23}. The errors are severely affected by the octant degeneracy of theta_{23}, and delta(s^2_{23}) is largely amplified by the Jacobian factor relating these two variables in a region near to the maximal mixing. The errors are also affected by the uncertainty due to unknown value of theta_{13}; delta(s^2_{23}) is doubled at off maximal in the second octant of theta_{23} where the effect is largest. To overcome this problem, we discuss combined analysis with nu_e appearance measurement in LBL experiments, or with reactor measurement of theta_{13}. For possible relevance of sub-leading effects even in the next-generation LBL experiments, we give a self-contained derivation of the survival probability to the next to leading order in s^2_{13} and Delta m^2_{21} / Delta m^2_{31}.

description: Reaction to social deprivation is generally discussed under three headings, i.e., aggression, avoidance, and acceptance. The present study investigated, on an exploratory basis, the relationship between one type of reaction, aggression--as reflected in the characteristics of automobiles, owned and operated; and relative deprivation in social status of Negroes in the U.S.A> as reflected in background or environmental and personal variables. What is the effect of segregation in childhood on the conspicuous consumption behavior of Negroes?
Status of Evidence for Neutrinoless Double Beta Decay, and the Future: GENIUS and GENIUS-TF

description: The first evidence for neutrinoless double beta decay has been observed in the HEIDELBERG-MOSCOW experiment, which is the most sensitive double beta decay experiment since ten years. This is the first evidence for lepton number violation and proves that the neutrino is a Majorana particle. It further shows that neutrino masses are degenerate. In addition it puts several stringent constraints on other physics beyond the Standard Model. The result from the HEIDELBERG-MOSCOW experiment is consistent with recent results from CMB investigations, with high energy cosmic rays, with the result from the g-2 experiment and with recent theoretical work. It is indirectly supported by the analysis of other Ge double beta experiments. The new project GENIUS will cover a wide range of the parameter space of predictions of SUSY for neutralinos as cold dark matter. Further it has the potential to be a real-time detector for low-energy ($pp$ and $^7$Be) solar neutrinos. A GENIUS Test Facility has come into operation on May 5, 2003. This is the first time that this novel technique for extreme background reduction in search for rare decays is applied under the background conditions of an underground laboratory.

description: In this article we find a four-dimensional metric for a large black hole immersed in dark matter. Specifically, we look for and find a static spherically symmetric black hole solution to the Einstein equations which gives, in the Newtonian limit, the rotation curves of galaxies, including the flat region and the Baryonic Tully-Fisher relation, and which has a regular horizon. We obtain as well the energy-momentum tensor of the dark matter sourcing this space-time and it turns, in special, to satisfy the four energy conditions (dominant, weak, null, and strong) everywhere outside the horizon. This black-hole-dark-matter system represents a successful simplified model for galaxies, opens a new area for exploring the relativistic regime of dark matter, and shows that the theory of General Relativity together with dark matter can account for the rotation curves of galaxies.
