description: Abstract: Shear-induced segregation, by particle size, is known in the flow of colloids and granular media, but is unexpected at the atomic level in the deformation of solid materials, especially at room temperature. In nanoscale wear tests of an Fe-based bulk metallic glass at room temperature, without significant surface heating, we find that intense shear localization under a scanned indenter tip can induce strong segregation of a dilute large-atom solute (Y) to planar regions that then crystallize as a Y-rich solid solution. There is stiffening of the material, and the underlying chemical and structural effects are characterized by transmission electron microscopy. The key influence of the soft Fe–Y interatomic interaction is investigated by ab-initio calculation. The driving force for the induced segregation, and its mechanisms, are considered by comparison with effects in other sheared media.

description: This special issue addresses the urgent threat of climate change to cultural heritage and presents a range of strategies for mitigation and adaptation. The research highlights the diverse impacts of rising temperatures, increased humidity, and extreme weather events on archaeological sites, historic buildings, museums and galleries. The papers provide evidence for a much-needed paradigm shift in the management of heritage conservation signifying a move away from habitual practices with narrowly focussed conceptions of risk towards sustainable and context-specific approaches. Case studies from Greece, the UK, the Philippines, and Egypt demonstrate the importance of localized solutions, the development of data-driven risk assessments, including environmental monitoring systems and the adaptive reuse of heritage structures. The studies also emphasize the critical need for carefully targeted climate control measures and a rejection of a default energy-intense climate management model based on outdated approaches and badly adapted control measures. The collection of papers in this volume, advocates for community engagement and collaboration among stakeholders to promote shared responsibility for heritage preservation. The findings reveal that conventionally used nominal standards are not universally applicable and call for more evidence-based approaches to collection care. By embracing these contextual strategies, the heritage sector can enhance its resilience, move away from traditional conventions and ensure the considered preservation of cultural heritage for current and future generations.
Singular nonlinear response in metals due to divergent Berry curvature: application to magneto-resistance in metals with type-II Weyl nodes

description: The physical properties of metals are often given by the sum of the contributions from the electrons consisting the Fermi surface (FS), and therefore, fine structures of the electronic bands and Bloch functions are often masked by the integral over FS. As a consequence, usually, the singular structures in the electronic bands are often not reflected to the macroscopic quantities. In this work, we investigate the anomaly-related magnetoresistance in metals with type-II Weyl nodes close to the FS, and find that the anomaly-related current increases divergently, showing a singular structure. Detailed analysis on a simple model with multiple Weyl nodes shows that the contribution to the magnetoresistance is dominated by the electrons in the vicinity of the Weyl nodes; this is related to the fact that the current is given by the square of the Berry curvature, which enhances the contribution from the electrons around the Weyl nodes. The above results potentially allows an estimate of the anomaly-induced current without precise information of the entire Band structure.

Helium giant stars as progenitors of rapidly fading Type Ibc supernovae

description: Type I rapidly fading supernovae (RFSNe) appear to originate from hydrogen-free stars with large radii that produce predominantly shock-cooling light curves, in contrast with more typical nickel-rich SNe Ibc. However, it remains to be determined what types of stars would produce bright shock-cooling light curves without significant contribution from radioactive nickel. Bare helium stars in the mass range ~2-4 solar masses are known to hydrostatically develop radii as large as 100 solar radii or more due to strong He and C shell burning outside of a core with a sharp density gradient. We produce several such stellar models and demonstrate that, when exploded, these helium giants can naturally produce RFSN light curves. Since many prototypical SNe Ibc should come from large-radius stars in this mass range as well, we predict that these RFSNe may be distinct from SNe Ibc solely due to the absence of substantial nickel.

description: A Fortran program for the calculation of the ground state properties of axially deformed even-even nuclei in the relativistic framework is presented. In this relativistic mean field (RMF) approach a set of coupled differential equations namely the Dirac equation with potential terms for the nucleons and the Glein-Gordon type equations with sources for the meson and the electromagnetic fields are to be solved self-consistently. The well tested basis expansion method is used for this purpose. Accordingly a set of harmonic oscillator basis generated by an axially deformed potential are used in the expansion. The solution gives the nucleon spinors, the fields and level occupancies, which are used in the calculation of the ground state properties.

Fast muscle in squid (Loligo pealei): contractile properties of a specialized muscle fibre type
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: SUMMARY The contractile properties of the transverse muscle of the tentacles and the transverse muscle of the arms of the squid Loligo pealei were investigated using small muscle fibre bundle preparations. In addition, transmission electron microscopy was used to measure the length of the thick myofilaments of the two muscle fibre types. The thick filament length of the cross-striated tentacle fibres was 0.81±0.08 μm (mean ± S.D, N=51) while that of the obliquely striated arm muscle fibres was 7.41±0.44 μm (N=58). The difference in thick filament length of the two muscle types was predicted to result in a much higher shortening velocity of the tentacle muscle compared with the arm muscle. This was tested by investigating the force/velocity relationship for isotonic shortening of the two muscle types. Fitting Hill9s equation to the results gave a maximum shortening velocity (Vmax, the intercept on the velocity axis) of 15.4±1.0 L0 s-1 (mean ± S.D., N=9) for the tentacle fibres and of 1.5±0.2 L0 s-1 (N=8) for the arm fibres, where L0 is the length at which peak isometric force was recorded. The difference in thick filament length was also predicted to result in lower peak tension in the tentacle versus the arm muscle. For the tentacle, the mean peak tetanic tension during a brief isometric tetanus (0.2s) of 131±56 mN mm-2 cross-sectional area (mean ± S.D., N=12) was observed at a stimulus frequency of 80 Hz, whereas the mean peak tetanic tension of the arm fibres during a brief isometric tetanus (0.2s) was 468±91 mN mm-2 (N=5) and was observed at a stimulus frequency of 160 Hz. The length/force relationships (expressed relative to L0) of the two muscle types were similar. The ratio of twitch force to peak tetanic force was 0.66 in the tentacle fibres, but only 0.03 in the arm fibres.

description: We have performed the first ab-initio calculations of a possible complex non-collinear magnetic structure in aluminium-rich Al-Mn liquids within the real-space tight-binding LMTO method. In our previous work we predicted the existence of large magnetic moments in Al-Mn liquids [A.M. Bratkovsky, A.V. Smirnov, D. N. Manh, and A. Pasturel, \prb {\bf 52}, 3056 (1995)] which has been very recently confirmed experimentally. Our present calculations show that there is a strong tendency for the moments on Mn to have a non-collinear (random) order retaining their large value of about 3~$μ_B$. The d-electrons on Mn demonstrate a pronounced non-rigid band behaviour which cannot be reproduced within a simple Stoner picture. The origin of the magnetism in these systems is a topological disorder which drives the moments formation and frustrates their directions in the liquid phase.

description: We present a multi-wavelength analysis of the four most relaxed clusters in the South Pole Telescope 2500 deg^2 survey, which lie at 0.55 < z < 0.75. This study, which utilizes new, deep data from Chandra and Hubble, along with ground-based spectroscopy from Gemini and Magellan, improves significantly on previous studies in both depth and angular resolution, allowing us to directly compare to clusters at z~0. We find that the temperature, density, and entropy profiles of the intracluster medium (ICM) are very similar among the four clusters, and share similar shapes to clusters at z~0. Specifically, we find no evidence for deviations from self similarity in the temperature profile over the radial range 10kpc < r < 1Mpc, implying that the processes responsible for preventing runaway cooling over the past >6 Gyr are, at least roughly, preserving self similarity. We find typical metallicities of ~0.3 Zsun in the bulk of the ICM, rising to ~0.5 Zsun in the inner ~100 kpc, and reaching ~1 Zsun at r < 10kpc. This central excess is similar in magnitude to what is observed in the most relaxed clusters at z~0, suggesting that both the global metallicity and the central excess that we see in cool core clusters at z~0 were in place very early in the cluster lifetime and, specifically, that the central excess is not due to late-time enrichment by the central galaxy. Consistent with observations at z~0, we measure a diversity of stellar populations in the central brightest cluster galaxies of these four clusters, with star formation rates spanning a factor of ~500, despite the similarity in cooling time, cooling rate, and central entropy. These data suggest that, while the details vary dramatically from system to system, runaway cooling has been broadly regulated in relaxed clusters over the past 6 Gyr.

description: We demonstrate that soft SUSY breaking introduced via replacement of the couplings of a rigid theory by spurion superfields has far reaching consequences. Substituting these modified couplings into renormalization constants, RG equations, solutions to these equations, fixed points, finiteness conditions, etc., one can get corresponding relations for the soft terms by a simple Taylor expansion over the Grassmannian variables. This way one can get new solutions of the RG equations. Some examples including the MSSM, SUSY GUTs and the N=2 Seiberg-Witten model are given.

Fertilization ecology of egg coats: Physical versus chemical contributions to fertilization success of free-spawned eggs
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: Free-spawned eggs are typically enclosed within accessory structures that are shed early in development. Most research on the role of these structures in fertilization has focused on chemical constituents and their influence on sperm-egg interaction. Here I test an alternative hypothesis that accessory structures play an important physical role in fertilization by increasing the size and buoyancy of the egg, making it a better target for sperm. In the sand dollar Dendraster excentricus, the jelly coat increases egg target size sixfold. At nonsaturating sperm concentrations, fertilization declined consistently following jelly coat removal by two independent methods. Regression analysis using a standard fertilization kinetics model found that 54-73% of this decline on average was predicted by changes in the rate of sperm-egg collision, resulting from changes in egg target size and density. Sperm swimming speed, a key parameter in the model, did not vary as a function of sperm concentration or exposure to egg-water. The organic cost of jelly is a fraction of that of the ovum, providing an efficient means of extending target size beyond the ovum size that is optimal for larval or juvenile development. These results support the hypothesis that physical attributes of jelly coats can account for a significant portion of their contribution to fertilization, and may help to explain why coats and other accessory structures are often substantially larger than expected from the nature of chemical interactions between egg and sperm.

description: Inverse coordination is an emerging novel chemical concept describing the formation of metal complexes in which the arrangement of acceptor and donor sites is opposite to that occurring in conventional coordination complexes. Inverse coordination complexes are formed around a non-metal species as central atom (ion or small molecule) surrounded by a number of metal atoms (ions) connected or not by internal bridging (intramolecular) linkers. This article illustrates the diversity of species described under this concept with structures in which the coordination center is nitrogen (mono- and poly-nitrogen moieties).

description: In most fields, computational models and data analysis have become a significant part of how research is performed, in addition to the more traditional theory and experiment. Mathematics is no exception to this trend. While the system of publication and credit for theory and experiment (journals and books, often monographs) has developed and has become an expected part of the culture, how research is shared and how candidates for hiring, promotion are evaluated, software (and data) do not have the same history. A group working as part of the FORCE11 community developed a set of principles for software citation that fit software into the journal citation system, allow software to be published and then cited, and there are now over 50,000 DOIs that have been issued for software. However, some challenges remain, including: promoting the idea of software citation to developers and users; collaborating with publishers to ensure that systems collect and retain required metadata; ensuring that the rest of the scholarly infrastructure, particularly indexing sites, include software; working with communities so that software efforts "count" and understanding how best to cite software that has not been published.

description: Nematic liquid crystals (NLCs) absorbed in a nonwoven of surface-treated silica nanofibres (SiO2-NFs) orient the director along the nonwoven thickness direction if the NLCs prefer homeotropic anchoring onto the fibre surface. The nonwoven has vacant spaces with the dimensions of 0.3 and 0.6 μm in the thickness and cross directions, respectively, bordered with SiO2-NFs with 93 nm in diameter. The SiO2-NF surface was treated with a silane-coupling agent to induce the homeotropic anchoring of NLC mesogens onto the surface. The nematic director is arranged radially from the fibres although it is more severely constrained by the proximity between fibre surfaces along the thickness direction. Consequently, the NLCs can align along the nonwoven thickness direction involving −1/2 wedge disclinations on both sides of the fibres.

description: Abstract
The main objective of this study is to investigate the status and features of academic
integrity among educators of universities in southern Ethiopia. The study designed
to achieve the objectives used quantitative approach where cross-sectional survey
design was implemented.Three hundred fifty five respondents were selected for the
study using multistage sampling method. The data were gathered using an academic
integrity scale measuring honesty, trust, respect, fairness, and responsibility. The
data gathered were organized and analyzed using SPSS – version – 24. Descriptive
and inferential statistical techniques were used to analyze the data. The finding
of the study revealed that significant number of the respondents (35.5%) was
moderate in their academic integrity; the academic integrity of 24.8 percent of
the respondents was low; 22.1 percent of them were poor in their academic integrity;
16.1 percent of them demonstrated high academic integrity while the percent of
the respondents who demonstrated very high academic integrity was 1.5 percent of
the total participants. Moreover, multiple linear regression analysis revealed that
all honesty, trust, respect, fairness and responsibility determine academic integrity
equally. As educators’ academic integrity contributes for educational quality in
higher institutions,universities should design and implement a program to change
educators’ academic integrity mindset, and find out and address factors that can it.

Types Nat. Hist. Mus. London.
etymology Gr cephalica, of the head, probably alluding to the enlarged head of the major.
diagnosis A very large, small-eyed species, immediately recognizable in the major by the low postpetiolar node in side view, prominent lobose subpostpetiolar process, broad, bell-shaped postpetiole seen from above, and completely foveolate body (including all of the gaster); and in the minor, by the very low petiolar and postpetiolar nodes, cylindrical overall shape of the petiole in side view, extended frontal lobes in dorsal-oblique view, occipital neck, and completely foveolate body (including all of the gaster). Measurements (mm) Major (north of Manaus, Brazil): HW 2.60, HL 2.66, SL 1.26, EL 0.26, PW 1.26. Minor (north of Manaus, Brazil): HW 0.98, HL 1.06, SL 1.12, EL 0.16, PW 0.66. Color Major: body dark reddish brown.
Minor: body light reddish brown except for the gaster, which is yellowish brown.
Range A very widespread species recorded over many localities from Veracruz, Mexico, to Amazonian Brazil and Bolivia, where it is often locally abundant. I have collected it on Tobago, which appears to be its farthest intrusion into the West Indies. In Costa Rica, Longino (1997) reports finding the species from sea level to 900 m.
Biology P. cephalica is an inhabitant of tropical forests, particularly in lowland areas. Colonies nest in rotten logs, stumps, and even the dead branches of standing trees a meter or more off the ground. The minors forage widely over the forest floor and up onto the trunks of standing trees. They feed on insects, are attracted to sugar baits, and also collect seeds. Using laboratory colonies, I demonstrated the extreme sensitivity of minor workers to the appearance of standing water in the nest: at the first sign of potential flooding -even a few drops -the minors initiate trail laying and issue an alarm that causes the colony to evacuate the nest within minutes (Wilson 1987c).

We first focus on the SO(5) model, which involves generalized T=1 pairing. Neither boson mean-field methods nor fermion-pair approximations are able to describe in detail neutron-proton pairing in this model. The analysis suggests, however, that the boson Hamiltonian obtained from a mapping of the fermion Hamiltonian contains a pairing force between bosons, pointing to the importance of boson-boson (or equivalently four-fermion) correlations with isospin T=0 and spin S=0. These correlations are investigated by carrying out a second boson mapping. Closed forms for the fermion wave functions are given in terms of the fermion-pair operators. Similar techniques are applied -- albeit in less detail -- to the SO(8) model, involving a competition between T=1 and T=0 pairing. Conclusions similar to those of the SO(5) analysis are reached regarding the importance of four-particle correlations in systems involving neutron-proton pairing.

description: The scatter of the spatially resolved star formation main sequence (SFMS) is investigated in order to reveal signatures about the processes of galaxy formation and evolution. We have assembled a sample of 355 nearby galaxies with spatially resolved Hα and mid-infrared fluxes from the Survey for Ionized Neutral Gas in Galaxies and the Wide-field Infrared Survey Explorer, respectively. We examine the impact of various star formation rate (SFR) and stellar mass transformations on the SFMS. Ranging from 10^6 to 10^11.5 M_sun and derived from color to mass-to-light ratio methods for mid-infrared bands, the stellar masses are internally consistent within their range of applicability and inherent systematic errors; a constant mass-to-light ratio also yields representative stellar masses. The various SFR estimates show intrinsic differences and produce noticeable vertical shifts in the SFMS, depending on the timescales and physics encompassed by the corresponding tracer. SFR estimates appear to break down on physical scales below 500 pc. We also examine the various sources of scatter in the spatially resolved SFMS and find morphology does not play a significant role. We identify three unique tracks across the SFMS by individual galaxies, delineated by a critical stellar mass density of log (Σ_M*)~7.5. Below this scale, the SFMS shows no clear trend and is likely driven by local, stochastic internal processes. Above this scale, all spatially resolved galaxies have comparable SFMS slopes but exhibit two different behaviors, resulting likely from the rate of mass accretion at the center of the galaxy.

description: Abstract
This study was conducted to describe the language learning strategies used by English
major students at Dilla University. To this end, all thirty English major second-year
students participated in the study. The study utilized a descriptive research design.
Data were gathered using Oxford’s Strategy Inventory for Language Learning (SILL)
and interviews. Data from interviews were analyzed qualitatively, whereas data
obtained through the questionnaire were analyzed using the Statistical Package for
Social Sciences (SPSS) version 20. To analyze the data, descriptive and inferential
statistics such as mean, standard deviation, one-way ANOVA, and post hoc tests were
applied to determine whether there is a statistically significant mean difference among
the groups’ language learning strategies. The findings claim that high achievers
outperformed their average and low achievers by employing more types and more
frequent use of language learning strategies. In the meantime, it was confirmed that
there exists a significant mean difference among

description: Abstract
The purpose of this study was to investigate BSc-graduated mathematics teachers’
understanding of some basic elementary geometry concepts. To conduct the study, a
descriptive survey design and an inferential T-test were employed. The study included
53 participants—43 males and 10 females—who came to attend the Post Graduate
Diploma in Teaching (PGDT) program at Dilla University Ethiopia in 2018–19 and
were chosen using convenience sampling techniques. A 15-item achievement test
on basic elementary geometry concepts in mathematics was used as an instrument
for the study. The findings revealed that, out of 15 concepts, 1.55 and 1.85 were
answered by female and male teachers, respectively. where they are perceived as
difficult to understand and solve by BSc-graduated mathematics teachers. There
was no significant difference between teachers in gender understanding and solving
elementary basic concepts in geometry (p = 0.372 greater than p = 0.05 level of
significance). As a result, it is recommended that extremely important BSc holders
in mathematics teachers skill up through their professional development program,
stakeholders and the MOE step up conscription efforts, and universities take action
such as a workshop to fill the gap.

description: Abstract: Biomolecular systems show how host–guest binding can induce changes in molecular behavior, which in turn impact the functions of the system. Here we report an artificial host–guest system where dynamic adaptation during guest binding alters both host conformation and guest dynamics. The self-assembled cage host employed here possesses concave walls and a chirotopic cavity. Complementarity between the curved surfaces of fullerenes and the inner surface of the host cavity leads the host to reconfigure stereochemically in order to bind these guests optimally. The curved molecule corannulene undergoes rapid bowl-to-bowl inversion at room temperature. Its inversion barrier is increased upon binding, however, and increased further upon formation of a ternary complex, where corannulene and a cycloalkane are both bound together. The chiral nature of the host also leads to clear differences in the NMR spectra of ternary complexes involving corannulene and one or the other enantiomer of a chiral guest, which enables the determination of enantiomeric excess by NMR.

description: We find significantly different diagnostic emission line ratios for the circumgalactic gas associated with galaxies of stellar masses above and below $10^{10.4}$ M$_\odot$ using SDSS spectroscopy. Specifically, in a sample of 17,393 galaxies, intersected by 18,535 lines of sight at projected radii between 10 and 50 kpc, we stack measured fluxes for nebular strong emission lines, [O {\small III}] $λ$5007, H$α$ and [N {\small II}] $\lambda6583$, and find that the gas surrounding the lower mass galaxies exhibits similar line ratios to those of gas ionized by star formation and that surrounding the higher mass galaxies similar to those of gas ionized by AGN or shocks. This finding highlights yet another characteristic of galaxies that is distinctly different above and below this stellar mass threshold, but one that is more closely connected to the gas accretion behavior hypothesized to be responsible for this dichotomy.

description: As a simple model for dark matter, we propose a QCD-like theory based on $\rm{SU}(2)$ gauge theory with one flavor of dark quark. The model is confining at low energy and we use lattice simulations to investigate the properties of the lowest-lying hadrons. Compared to QCD, the theory has several peculiar differences: there are no Goldstone bosons or chiral symmetry restoration when the dark quark becomes massless; the usual global baryon number symmetry is enlarged to $\rm{SU}(2)_B$, resembling isospin; and baryons and mesons are unified together in $\rm{SU}(2)_B$ iso-multiplets. We argue that the lightest baryon, a vector boson, is a stable dark matter candidate and is a composite realization of the hidden vector dark matter scenario. The model naturally includes a lighter state, the analog of the $η^\prime$ in QCD, for dark matter to annihilate into to set the relic density via thermal freeze-out. Dark matter baryons may also be asymmetric, strongly self-interacting, or have their relic density set via $3 \to 2$ cannibalizing transitions. We discuss some experimental implications of coupling dark baryons to the Higgs portal.

description: Motivated by the concept of ideal mutual statistics, we study a multispecies Calogero-Sutherland model in which the interaction parameters and masses satisfy some specific relations. The ground state is exactly solvable if those relations hold, both on a circle and on a line with a simple harmonic potential. In the latter case, the one-particle densities can be obtained using a generalization of the Thomas-Fermi method. We calculate the second virial coefficients in the high temperature expansion for the pressure. We show that the low-energy excitations are the same as those of a Gaussian conformal field theory. Finally, we discuss similar relations between the statistics parameters and charges for a multispecies anyon model in a magnetic field.

We show that if $V$ attains local minimum and $Γ$ attains global maximum at the same point or $V$ attains global minimum and $Γ$ attains local maximum at the same point, then there exists a positive solution for sufficiently small $\hslash>0$.

description: In this paper we study some low energy effects of a light stabilized radion in the Randall-Sundrum scenario. We find that the NLC 500 with its projected precision level will be able to probe the radion contribution to the anomalous magnetic moment and electric quadrupole moment of W boson for values of radion vev up to 500 Gev. On the other hand the BNL experiment E821 will be able to test the radion contribution to $a_μ$ for 1 Tev radion vev and $m_ϕ\le m_μ$. We have also shown that the higgs-radion mixing induces a 2.6% correction in the WWh coupling. Finally by comparing the radionstrahlung with the higgsstrahlung process we have found that the LEPI bound on the higgs mass based on $Z\to hl\bar{l}$ decay mode suggests a lower bound of about 35 Gev on the radion mass.
