description: Let X be a compact 2-manifold with nonempty boundary dX and let f: (X, dX) --> (X, dX) be a boundary-preserving map. Denote by MF_d[f] the minimum number of fixed point among all boundary-preserving maps that are homotopic through boundary-preserving maps to f. The relative Nielsen number N_d(f) is the sum of the number of essential fixed point classes of the restriction f-bar : dX --> dX and the number of essential fixed point classes of f that do not contain essential fixed point classes of f-bar. We prove that if X is the Moebius band with one (open) disc removed, then MF_d[f] - N_d(f) < 2 for all maps f : (X, dX) --> (X, dX). This result is the final step in the boundary-Wecken classification of surfaces, which is as follows. If X is the disc, annulus or Moebius band, then X is boundary-Wecken, that is, MF_d[f] = N_d(f) for all boundary-preserving maps. If X is the disc with two discs removed or the Moebius band with one disc removed, then X is not boundary-Wecken, but MF_d[f] - N_d(f) < 2. All other surfaces are totally non-boundary-Wecken, that is, given an integer k > 0, there is a map $f_k : (X, dX) --> (X, dX) such that MF_d[f_k] - N_d(f_k) >= k.

description: Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing the heat flow in the majority of experiments, have been identified and derived theoretically. However, a full picture encompassing experimentally relevant effects such as reduced dimensionality, material interfaces, and disorder is in its infancy, and has not been tested extensively. Here, we study the electron-phonon heat flow in a thin gold film on a SiO${}_2$ platform below 100 mK using supercurrent thermometry. We find the power law exponent to be modified from 5.1 to 4.6 as the platform is micromachined and released from its substrate. We attribute this change to a modified phonon spectrum. The findings are compared to past experiments and theoretical models.

description: We study interaction-induced Mott insulators, and their topological properties in a 1D non-Hermitian strongly-correlated spinful fermionic superlattice system with either nonreciprocal hopping or complex-valued interaction. For the nonreciprocal hopping case, the low-energy neutral excitation spectrum is sensitive to boundary conditions, which is a manifestation of the non-Hermitian skin effect. However, unlike the single-particle case, particle density of strongly correlated system does not suffer from the non-Hermitian skin effect due to the Pauli exclusion principle and repulsive interactions. Moreover, the anomalous boundary effect occurs due to the interplay of nonreciprocal hopping, superlattice potential, and strong correlations, where some in-gap modes, for both the neutral and charge excitation spectra, show no edge excitations defined via only the right eigenvectors. We show that these edge excitations of the in-gap states can be correctly characterized by only biorthogonal eigenvectors. Furthermore, the topological Mott phase, with gapless particle excitations around boundaries, exists even for the purely imaginary-valued interaction, where the continuous quantum Zeno effect leads to the effective on-site repulsion between two-component fermions.

description: Recently observed splitting in angular resolved photoemission spectroscopy (ARPES) on $\chem{Bi_2Sr_{2-x}La_xCuO_{6+δ}}$ high--temperature superconductor (Janowitz C. {\it et al.}, {\it Europhys. Lett.}, {\bf 60} (2002) 615) is interpreted within the phenomenological Luttinger--liquid framework, in which both the non--Fermi liquid scaling exponent of the spectral function and the spin--charge separation are introduced. The anomalous Green function with adjustable parameters fits very well to the Fermi edge and the low--energy part of ARPES along the $Γ-M$ line in the Brillouin zone. In contrast to one--dimensional models with Luttinger--liquid behavior we find that both the anomalous scaling $α$ and the parameter $δ$ describing the spin--charge separation are momentum dependent. The higher--energy part of the spectra is not accounted for by this simple Luttinger--liquid form of the Green function. In this energy regime additional scattering processes are plausible to produce the experimentally observed wide incoherent background, which diminishes as the inverse of the energy.

description: Multi-view capture systems are complex systems to engineer. They require technical knowledge to install and intricate processes to setup related mainly to the sensors' spatial alignment (i.e. external calibration). However, with the ongoing developments in new production methods, we are now at a position where the production of high quality realistic 3D assets is possible even with commodity sensors. Nonetheless, the capturing systems developed with these methods are heavily intertwined with the methods themselves, relying on custom solutions and seldom - if not at all - publicly available. In light of this, we design, develop and publicly offer a multi-view capture system based on the latest RGB-D sensor technology. For our system, we develop a portable and easy-to-use external calibration method that greatly reduces the effort and knowledge required, as well as simplify the overall process.

description: Objetivos: O dissulfiram é utilizado no tratamento do alcoolismo crónico há mais de 50 anos. Este fármaco interfere no metabolismo do etanol e encoraja a abstinência por causar sintomas desagradáveis com a ingestão concomitante de álcool. Efeitos adversos incluem casos raros de neuropatia óptica bilateral. O objetivo deste artigo é descrever um caso clínico de neuropatia óptica tóxica causada por dissulfiram. Métodos: Descrição do caso clínico e breve revisão bibliográfica. Resultados: Reporta-se o caso de um homem de 56 anos, tratado nos últimos 7 anos com dissulfiram por alcoolismo crónico, que recorreu ao Serviço de Urgência de Oftalmologia por diminuição da acuidade visual bilateral severa com 2 meses de evolução, associada a uma neuropatia óptica. Extensa investigação etiológica revelou como causa provável uma neuropatia óptica tóxica causada pelo dissulfiram. A interrupção do dissulfiram resultou em rápida e significativa recuperação visual. Conclusões: Na presença de uma neuropatia óptica com suspeita de toxicidade pelo dissulfiram, a cessação do fármaco é mandatória. O prognóstico visual é habitualmente bom, conforme ilustrado no nosso caso e descrito na literatura.

description: The effect of one-gluon-exchange (OGE) pair-currents on the ratio $μ_p G_E^p/G_M^p$ for the proton is investigated within a nonrelativistic constituent quark model (CQM) starting from $SU(6) \times O(3)$ nucleon wave functions, but with relativistic corrections. We found that the OGE pair-currents are important to reproduce well the ratio $μ_p G_E^p/G_M^p$. With the assumption that the OGE pair-currents are the driving mechanism for the violation of the scaling law we give a prediction for the ratio $μ_n G_E^n/G_M^n$ of the neutron.

description: The time taken by a wave packet to cross through a finite layered $PT$-symmetric system is calculated by stationary phase method. We consider the $PT$- symmetric system of fix spatial length $L$ consisting of $N$ units of the potential system `$+iV$' and `$-iV$' of equal width `$b$' such that $L=2Nb$. In the limit of large `$b$', the tunneling time is found to be independent of $L$ and therefore the layered $PT$-symmetric system display the Hartman effect. The interesting limit of $N \rightarrow \infty$ such that $L$ remains finite is investigated analytically. In this limit the tunneling time matches with the time taken to cross an empty space of length $L$. The result of this limiting case $N \rightarrow \infty$ also shows the consistency of phase space method of calculating the tunneling time despite the existence of controversial Hartman effect. The reason of Hartman effect is unknown to present day however the other definitions of tunneling time that indicate a delay which depends upon the length of traversing region have been effectively ruled out by recent attosecond measurements.

REMARKS
 One female specimen (examined) possibly belonging to this species has been collected in Seychelles (Jin & Kevan 1992). Males would be required to confirm this identification. Nevertheless, it is absolutely clear that this female specimen does not belong to the known endemic Phisidini from Seychelles. Phisis peregrina is a very widespread species, occurring from southwestern Pacific to Indian Ocean.Other Ensifera species very widespread on Pacific and Indian Ocean islands are occurring on SWIO islands, such as Myrmecophilus americanus Saussure, 1877 (Wetterer & Hugel 2008) and Xiphidiopsis lita Hebard, 1922 (Hugel 2010a).

description: TIGER integral-field spectrography and HST/WFPC2 imaging of the E3 galaxy NGC 2974 are used to derive the kinematics of the stellar and ionized gas components in its central 500 pc. We derive a numerical two-integral distribution function from a MGE mass model using the HQ formalism. The TIGER as well as published long-slit stellar kinematics are well fitted with this self-consistent model, requiring neither the addition of a significant mass contribution from a hidden disc structure, nor the presence of a central dark mass. The data reveal the presence of a striking, highly contrasted, two-arm gaseous spiral structure within a radius of ~200 pc, corresponding to a total mass of 6.8x10^4 Msun of ionized gas. We use a deconvolved TIGER datacube to probe its kinematics at a resolution of about 0.35 arcsec. Strong departures from circular motions are observed, as well as high velocity dispersion values on the inner side of the arms. We interpret the observed gas morphology and kinematics as the signature of streaming gas flows driven by a ~540 pc diameter bar with Ome=700+/-100 km/s/kpc. This hypothesis is strongly supported by the predictions of a density wave model. This model predicts that the bar should lie at about 35 degree from the line of nodes, and implies gas inflow towards the central ~50 pc. The quadrupole pertubation due to this bar is estimated to represent less than 2% of the underlying gravitational potential. Despite its weakness, the inner bar of NGC 2974 may be able to drive some gas within a 10 pc radius. We suggest that the presence of such inner bars might be more common among early-type disk galaxies than is generally thought, and that deep high-resolution emission-line imagery may be the best way to detect such structures.

description: The autophagy-associated transmembrane protein EI24 is associated with cancer growth and patient survival. We aimed to explore the prognostic role and immune infiltration characteristics of EI24 at a pan-cancer level. We collected data from multiple databases to explore the expression and prognostic role of EI24 in various cancers. Correlations between EI24 expression and DNA methylation, RNA modification, tumor mutation burden (TMB), microsatellite instability (MSI), immune moderator, immune checkpoint-related genes, the tumor immune microenvironment, and clinicopathological characteristics were analyzed. Finally, immunohistochemistry and western blotting were performed to validate the protein levels of EI24 in different tumors. Differential expression of EI24 was observed in most cancer types compared to non-cancerous tissues. EI24 showed a significant association with prognosis and may represent a new indicator of prognosis in patients with cancer. In most cancers, EI24 is closely associated with tumor immunity and interacts with various immune cells. Moreover, significant correlations were observed between EI24 expression and RNA modification, TMB, MSI, immune moderators, and immune checkpoint-related genes. This study provides new insights into the functions and clinical value of EI24 in different tumors and suggests that EI24 may serve as a promising biomarker or therapeutic target for cancer management.

description: Business and financial records for 1999 from 314 New York dairy farm businesses are summarized and analyzed. This analysis demonstrates the use of cash accounting with accrual adjustments to measure farm profitability, cash flow, financial performance, and costs of producing milk. Traditional methods of analyzing dairy farm businesses are combined with improved evaluation techniques to show the relationship between good management performance and financial success. The farms in the project averaged 224 cows per farm and 21,439 pounds of milk sold per cow, which represent above average size and management level for New York dairy farms. Net farm income excluding appreciation, which is the return to the operator's labor, management, capital, and other unpaid family labor, averaged $122,210 per farm. The rate of return including appreciation to all capital invested in the farm business averaged 9.7 percent. Differences in profitability between farms continue to widen. The top 10 percent of farms average net farm income excluding appreciation was $578,366, while the lowest 10 percent was a negative $10,114. Rates of return on equity with appreciation ranged from 36 percent to negative 31 percent from the highest 10 percent to the lowest 10 percent of farms. Farms adopting bovine somatotropin (bST) experienced greater increases in milk production, had larger herds and were more profitable than farms not adopting bST. Farms adopting rotational grazing generally produced less milk per cow than non-grazing farms, but had somewhat lower costs of production and higher profitability. However, one should not conclude that adoption of these technologies alone were responsible for differences in performance. Large freestall farms averaged the highest milk output per cow and per worker, the lowest total cost of production and investment per cow, and the greatest returns to labor, management and capital. Farms milking three times a day (3X) were larger, produced more milk per cow and were more profitable than herds milking two times per day (2X). Operating cost per cwt. of milk was $0.03/cwt. higher for 3X than 2X milking herds, while output per cow was 4,159 pounds higher.

description: US agricultural economic growth in this century has been characterized by a slow rise in the demand for food and faster growth in farm output as against nonfarm productivity. In such an environment, one expects the size of the farm sector to decline as a share of the rest of the economy. What is not so clear is the effectiveness of the price system in signaling the appropriate resource adjustments or of the resource market in responding to available signals. We examine four terms-of-trade measures conceptually and, since 1929, empirically. We find that even distortions from farm programs have not offset the long-term trend of declining terms of trade. Labor and capital markets respond, albeit imperfectly and slowly.

description: The extent to which inflation has eroded the real purchasing power of public agricultural research budgets is poorly understood. Official Government research and development (R&D) statistics use the gross national product (GNP) deflator to express research expenditures in constant dollars, despite the serious shortcomings of such a broad indicator of inflation for deflating research expenditures. A State Agricultural Experiment Station (SAES) research price index is calculated in this paper and compared with the GNP deflator. The GNP deflator substantially underestimated the rate of inflation in SAES research in recent years mainly due to real growth in faculty compensation during the 1980's. The divergence between the SAES research price index calcuated in this study and the GNP deflator indicates that the purchasing power of SAES research is significantly less than estimates based on the GNP deflator would suggest.

description: We report a numerical calculation of the elastic constants of the fcc and hcp crystal phases of monodisperse hard-sphere colloids. Surprisingly, some of these elastic constants are very different (up to 20%), even though the free energy, pressure and bulk compressibility of the two crystal structures are very nearly equal. As a consequence, a moderate deformation of a hard-sphere crystal may make the hcp phase more stable than the fcc phase. This finding has implications for the design of patterned templates to grow colloidal hcp crystals. We also find that, below close packing, there is a small, but significant, difference between the distances between hexagonal layers (c/a ratios) of fcc and hcp crystals.

description: Refractive surgery has undergone an extraordinary growth in recent decades, both in technical sophistication and in its popularity among patients. The goal of this work is to present current concepts on corneal Excimer laser refractive surgery. The authors, based on a comprehensive review of the literature and on their own experience, discuss practical topics regarding patient selection and evaluation, procedure choice, different aspects of surgical technique, and post-operative follow-up recommendations. The discussion is focused on the two most popular Excimer procedures: LASIK and PRK. Clinical good conduct regarding patient evaluation is reviewed, focusing on appropriate patient selection and on rigorous assessment of the patient’s pre-operative status. Contra-indications, absolute and relative, as well as specific advantages of both procedures are discussed. Optimal maximum attempted correction values are proposed. The importance of rigorous screening for post-operative ectasia at-risk patients is acknowledged. New advances in screening devices and concepts are discussed. Long-term follow-up of patients is essential for outcome analysis and improvement: practical guidance is suggested and long-term results available are reviewed.

description: The extraction of the isovector s-wave pi N amplitude from pionic atoms is studied with special emphasis on uncertainties and their dependence on the assumptions made regarding the neutron density distributions in nuclei and on the size of the data base used . Only `global' analyses of pionic-atom data reveal a discrepancy between the extracted isovector s-wave pi N amplitude b_1=-0.108\pm0.007 m_π^{-1} and its free pi N counterpart b_1^{free}=-0.0885^{+0.0010}_{-0.0021} m_π^{-1}, where the uncertainty in the neutron densities is included in the error analysis. The role of `deeply bound' pionic atom states is discussed and the reason for failure of these states to provide new information is explained.

description: Older adults’ health and quality of life, proxies for aging well, are tied to activity engagement. Recent research indicates studying the perspective of older adults through their personal stories is key to understanding the phenomenon of occupational engagement as experienced day-to-day. To uncover the lived experience of older adults within their natural settings to better understand the phenomenon of activity engagement. This new knowledge informs programming options suited to older adults’ wants and needs. Ten community-dwelling older adults (5 female, 5 male mean 79 years) were studied. Researchers performed phenomenological interpretive analysis (IPA) with multiple coders and member cheques to triangulate findings. Daily activities revolved around three themes: 1) Perspectives of self-identity are viewed as consistent throughout the lifespan; 2) Civic engagement is beneficial for social support and self-efficacy; and 3) Philosophical outlook influences activity choices and outlooks centred on altruism are critical to continued activity engagement. Seven of the ten participants expressed an overall positive outlook on aging. Three participants described a negative outlook on aging, expressed more difficulty with activity engagement, but reported desire to help others. These themes provide a basis for programming to increase activity engagement with older adults in the community.

description: Technical change is dynamic, recursive, and endogenous to the economic system. However, empirical studies usually treat technology as exogenous, defining technical change in terms of its end result changes in some production possibilities set. An endogenous view of technical change is necessary to understand, anticipate, and perhaps alter the development and use of new technologies and their associated problems. This article outlines a conceptual framework in which technical change is endogenous. The framework accounts for the dynamic and recursive interactions between research and development activities, the adoption and diffusion of new innovations, and the regulatory and institutional environment. As an example, the development of glyphosate-tolerant crops is discussed to show how the framework can be used to identify, organize, and understand the important variables and relationships for a specific case of technical change.

description: We discuss the time evolution of quotation of stocks and commodities and show that they form an Ising chain. We show that transaction costs induce arbitrage risk that usually is neglected. The full analysis of the portfolio theory is computationally complex but the latest development in quantum computation theory suggests that such a task can be performed on quantum computers.

description: Purpose: To evaluate surgical success rates and complications in patients with acquired nasolacrimal duct obstruction that underwent external dacryocystorhinostomy (DCR) with bicanalicular intubation. Methods: 63 external DCR’s performed in 58 patients were retrospectively evaluated. The variables analyzed were: age, gender, initial signs and symptoms, complications, surgical success rate and reoperations. Surgical success was defined by the presence of anatomical patency associated with resolution of epiphora (full success) or improvement of epiphora (partial success). All cases with persistent epiphora without anatomical patency or cases of recurrent dacryocystitis were classified as unsuccessful. Results: Patients mean age was 63.13 years, with female predominance (84.5%). Epiphora was the most frequent initial symptoms (71.4%). Of the 63 surgeries, fifty-five were first interventions and 8 were reoperations. Intraoperative and postoperative complications were unusual. In the postoperative complications, we must emphasize those related with silicone tube, with 3 cases of tube prolapse and 2 case of early tube extrusion. Surgery was unsuccessful in 6 cases (9.5%). Conclusions: Surgical success rate (full + partial) with external DCR was 90,5%. This surgical technique is a great option in the treatment of nasolacrimal duct obstructions, with high surgical success rates and low rate of complications. However, intraoperative intubation is not free of complications.

description: Proton and neutron densities have been obtained for the even-even isotopes of Sn from $^{100}$Sn to $^{176}$Sn using a Hartree-Fock-Bogoliubov model with a Skyrme interaction. The matter densities so defined have been used with realistic nucleon-nucleon interactions in a folding model to specify optical potentials for the elastic scattering of protons with energies in the range 40 to 200 MeV. Those potentials have been used to make predictions of the differential cross sections and spin observables for proton scattering. As the target mass increases, the emergence of the neutron skin in the Sn isotopes is revealed by marked effects in the differential cross section. Comparisons with available data show how similar scattering data for the neutron-rich isotopes may provide constraints for the model structures.

Off-shell pairing correlations from meson-exchange theory of nuclear forces

description: We develop a model of off-mass-shell pairing correlations in nuclear systems, which is based on the meson-exchange picture of nuclear interactions. The temporal retardations in the model are generated by the Fock-exchange diagrams. The kernel of the complex gap equation for baryons is related to the in-medium spectral function of mesons, which is evaluated nonperturbatively in the random phase approximation. The model is applied to the low-density neutron matter in neutron star crusts by separating the interaction into a long-range one-pion-exchange component and a short-range component parametrized in terms of Landau Fermi liquid parameters. The resulting Eliashberg-type coupled nonlinear integral equations are solved by an iterative procedure.We find that the self-energies extend to off-shell energies of the order of several tens of MeV. At low energies the damping of the neutron pair correlations due to the coupling to the pionic modes is small, but becomes increasingly important as the energy is increased. We discuss an improved quasiclassical approximation under which the numerical solutions are obtained.

description: Although systematic and scoping reviews have identified a range of interventions for persons experiencing homelessness, no known reviews have captured the range and quality of intervention studies aimed at supporting a transition from homelessness. To capture the range and quality of occupational therapy intervention studies aimed at supporting a transition to housing following homelessness. Using Joanna Briggs Institute (JBI) guidelines, we conducted a systematic review including a critical appraisal and narrative synthesis of experimental studies. Eleven studies were included. Critical appraisal scores ranged from 33.3 to 88.9 of a possible score of 100 (Mdn = 62.5; IQR = 33.4). The majority of studies evaluated interventions for the development of life skills (n = 9; 81.8%), and all were conducted in the USA. Several of the included studies were exploratory evaluation and feasibility studies, and all were quasi-experimental in design. Only three studies (27.2%) incorporated a control group. Intervention strategies included (1) integrated group and individual life skills interventions (n = 6); (2) group-based life skills interventions (n = 3); and (3) psychosocial and consultative interventions (n = 2). Research evaluating occupational therapy interventions aimed at supporting homeless individuals as they transition to housing is in an early stage of development. Implications for research and practice are discussed.
Hard convex lens-shaped particles: Characterization of dense disordered packings

description: Among the family of hard convex lens-shaped particles (lenses), the one with aspect ratio equal to 2/3 is `optimal' in the sense that the maximally random jammed (MRJ) packings of such lenses achieve the highest packing fraction $ϕ_{\rm MRJ} \simeq 0.73$. This value is only a few percent lower than $ϕ_{\rm DKP} = 0.76210\dots$, the packing fraction of the corresponding densest-known crystalline (degenerate) packings. By exploiting the appreciably reduced propensity that a system of such optimal lenses has to positionally and orientationally order, disordered packings of them are progressively generated by a Monte Carlo method-based procedure from the dilute equilibrium isotropic fluid phase to the dense nonequilibrium MRJ state. This allows one to closely monitor how the (micro)structure of these packings changes in the process of formation of the MRJ state. The gradual changes undergone by the many structural descriptors calculated can coherently and consistently be traced back to the gradual increase in contacts between the hard particles until the isostatic mean value of 10 contact neighbors per lens is reached at the effectively hyperuniform MRJ state. Compared to the MRJ state of hard spheres, the MRJ state of such optimal lenses is denser (less porous), more disordered, and rattler-free. This set of characteristics makes them good glass formers. It is possible that this conclusion may also hold for other hard convex uniaxial particles with a correspondingly similar aspect ratio, be they oblate or prolate, and that, by using suitable biaxial variants of them, that set of characteristics might further improve.

description: This paper investigates the configurational entropic content of hadron-nucleus collisions. Hadron multiplicities and Au nuclei are employed to compute the critical points of the configurational entropy as a function of the saturation scale in deep inelastic scatterings, in QCD. The results match phenomenological data to the precision of 0.39%.
