description: Chronic obstructive pulmonary disease (COPD) is a major burden of healthcare worldwide. We aimed to determine the effects of PDE-5 inhibitors on clinical outcomes and haemodynamic parameters in patients with COPD. A PROSPERO-registered systematic review and meta-analysis (identification number CRD42021227578) were performed to analyse the effects of PDE-5 inhibitors in patients with COPD. Data were sourced from MEDLINE, EMBASE, Cochrane Register of Controlled Trials and "ClinicalTrials.gov." Randomised controlled trials (RCTs) comparing PDE-5 inhibitors with control in patients with COPD were included. Quality assessment was carried out using the Cochrane Collaboration’s tool for assessing the risk of bias in randomised trials. The pooled mean difference of 6-minute walk distance (6MWD) and mean pulmonary arterial pressure based on inverse variance estimation were analysed with a fixed-effect model or random-effects model meta-analysis. Nine RCTs involving 414 patients were included in the review. There was no significant difference in 6MWD (mean difference = 22.06 metres, 95% confidence interval (CI), −5.80 to 49.91). However, there was a statistically significant difference between PDE-5 inhibitor and control groups in mean pulmonary artery pressure (mean difference = −3.83 mmHg, 95% CI, −5.93 to −1.74). Headaches were the most common adverse event, occurring significantly in the PDE-5 inhibitor intervention group (odds ratio 3.83, 95% CI, 1.49 to 9.86). This systematic review indicates that PDE-5 inhibitors do not improve exercise capacity despite some possible improvements in haemodynamic parameters in COPD patients.

description: The preponderance of employing unauthorized foreign-born immigrant workers in the farm labor force has made immigration policy a major issue for agriculture sector. The focal points of the policy discussions include two sides of the same coin: to what extent farm growers experience labor shortages and to what extent the immigrant farm workers affect the economic opportunities of native farm workers who are mostly less-educated. In this paper we propose a three-layer nested CES framework to model the labor demand in agricultural sector and empirically investigate the substitutability among heterogeneous farm worker groups defined by different age and education levels as well as immigration status. Using wages and employment information aggregated at different education-age-year cells from the National Agricultural Worker Survey (NAWS) data over the period of 1989 and 2012, we find little evidence that inflows of immigrants are associated with significant impact on native farm workers across different age and education groups. Within a specific age-education cell, the point estimate of the elasticity of substitution between immigrant and native farm workers is around 2. Our findings has important policy implication for the need to streamline the H-2A guest worker program which was intended by legislators to decrease the size of unauthorized immigrant workers meanwhile alleviate the potential labor shortage issues.
Dissipative Particle Dynamics for Directed Self-Assembly of Block Copolymers

Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: The dissipative particle dynamics (DPD) simulation method has been shown to be a promising tool to study self-assembly of soft matter systems. In particular, it has been used to study block copolymer (BCP) self-assembly. However, previous parametrizations of this model are not able to capture most of the rich phase behaviors of block copolymers in thin films nor in directed self-assembly (chemoepitaxy or graphoepitaxy). Here we extend the applicability of the DPD method for BCPs to make it applicable to thin films and directed self-assembly. Our new reparametrization is able to reproduce the bulk phase behavior, but also manages to predict thin film structures obtained experimentally from chemoepitaxy or graphoepitaxy. A number of different complex structures, such as bilayer nanomeshes, 90° bend structures, circular cylinders/lamellae and Frank-Kasper phases directed by trenches, post arrays or chemically patterned substrate have all been reproduced in this work. This reparametrized DPD model should serves as a powerful tool to predict BCP self-assembly, especially in some complex systems where it is difficult to implement SCFT.

description: Abstract: Robust time-series of direct observations of jellyfish abundance are not available for many ecosystems, leaving it difficult to determine changes in jellyfish abundance, the possible causes (e.g. climate change) or the consequences (e.g. trophic cascades). We sought an indirect ecological route to reconstruct jellyfish abundance in the Irish Sea: since zooplankton are jellyfish prey, historic variability in zooplankton communities may provide proxies for jellyfish abundance. We determined the Bayesian ecological network of jellyfish–zooplankton dependencies using jellyfish- and zooplankton-abundance data obtained using nets during a 2-week cruise to the Irish Sea in 2008. This network revealed that Aurelia aurita abundance was dependent on zooplankton groups Warm Temperate and Temperate Oceanic as defined by previous zooplankton ecology work. We then determined historic zooplankton networks across the Irish Sea from abundance data from Continuous Plankton Recorder surveys conducted between 1970 and 2000. Transposing the 2008 spatial dependencies onto the historic networks revealed that Aurelia abundance was more strongly dependent over time on sea surface temperature than on the zooplankton community. The generalist predatory abilities of Aurelia may have insulated this jellyfish over the 1985 regime shift when zooplankton composition in the Irish Sea changed abruptly, and also help explain its globally widespread distribution.

description: Recently, a class of partition functions associated with higher rank rational and trigonometric integrable models were introduced by Foda and Manabe. We use the dynamical $R$-matrix of the elliptic quantum group $E_{τ,η}(gl_3)$ to introduce an elliptic analogue of the partition functions associated with $E_{τ,η}(gl_3)$. We investigate the partition functions of Foda-Manabe type by developing a nested version of the elliptic Izergin-Korepin analysis, and present the explicit forms as symmetrization of multivariable elliptic functions. We show that special cases are essentially the elliptic weights functions introduced in the works by Rimányi-Tarasov-Varchenko, Konno, Felder-Rimányi-Varchenko.

description: We consider the problem of determining the beta-functions for any reduced effective field theory. Even though not all the Green's functions of a reduced effective field theory are renormalizable, unlike the full effective field theory, certain effective beta- functions for the reduced set of couplings may be calculated without having to introduce vertices in the Feynman rules for redundant operators. These effective beta-functions suffice to apply the renormalization group equation to any transition amplitude (i.e., S- matrix element), thereby rendering reduced effective field theories no more cumbersome than traditionally renormalizable field theories. These effective beta-functions may equally be regarded as the running of couplings for a particular redefinition of the fields.

Rhotana suttoni

description: Rhotana suttoni Zelazny, sp. nov.
(Fig. 252)
 Description. Forewings 1.8 times longer than wide, length about 4.7 mm. Colour stramineous; apex of clypeus and parts of the legs light orange-brown. Forewings glassy, lightly infuscated in apical third and along most veins. Veins orange-red but claval and basal sections of cubital veins stramineous. Hindwings lightly infuscated with most veins orange. Facial carinae contiguous up to lower margin of eyes; subantennal processes well -, lateral carinae of pronotum poorly developed. Forewings with apical section of Sc strongly sinuate; a small triangle at base of Ms1; Ms1 branched at basal third, Ms1b connected to middle part of Cu1 by a short crossvein. Pygofer of male genitalia with a pair of prominent, pointed lateral projections. Genital styles with a short proximal and an elongated distal dorsal process, a small hump between both. Aedeagus short with two needle-like terminal processes.
 Etymology. The species is named for the collector and ' suttoni ' is a latinized noun used in the genitive case.
 Type material. Holotype ♂ (forewing 4.7 mm), BRUNEI; labels: 1) Brunei, Labi / Bukit Teraja / 30km S.E. of Seria / 21–28.iii.1979 2) Primary mixed/dipterocarp/forest, alt. 60m. 3) light trap 2/ 50m. above ground/ L. Sutton / B.M. 1985-50 (BMNH).
 Distribution. Borneo (Brunei).
 Diagnosis. Rhotana suttoni resembles closely R. venosa Distant which also occurs in Borneo. Externally it can be separated from most specimens of R. venosa by its mesonotum, rostrum, legs and forewing veins lacking the brown coloration and by the forewings having more orange-red veins. However, a few specimens of R. venosa approach R. suttoni in coloration. Males of both species can be readily distinguished by the structure of the aedeagus.

description: We construct a left-right symmetric model based on the gauge group $SU(2)_L\times SU(2)_R\times U(1)_{B-L}$ in five dimensions where both the gauge bosons and fermions reside in all five dimensions. The orbifold boundary conditions are used not only to break the gauge symmetry down to $SU(2)_L\times U(1)_Y\times U(1)_{Y'}$ but also to ``project'' the right handed neutrino out of the zero mode part of the spectrum, providing a new way to understand the small neutrino masses without adding (singlet) bulk neutrinos. This formulation of the left-right model has also two new features: (i) it avoids most existing phenomenological bounds on the scale of the right handed $W_R$ boson allowing for the possibility that the right handed gauge bosons could have masses under a TeV, and (ii) it predicts a stable lepton with mass of order of the inverse radius of the fifth dimension.

description: Food safety receives an escalating attention since the 2008 milk scandal in China. Chinese government faces a great challenge to safeguard the safety of food supply chain due to the significant fermentation of producers and weak institutional resources to monitor and enforce food safety standards. Chinese farm households often practice two separate production systems for the same crop for the market and self-consumption separately and, thus the so called “One Farm Household, Two Production Systems” (OFH-TPS) gain the popularity in the recent years. This study provides both a theoretical framework to model the OFH-TPS decision and an empirical analysis to identify factors affecting the OFH-TPS decision using household survey data. We find that information asymmetry of product quality and measures to reduce the asymmetry such as product inspections and certifications play an important role in the OFH-TPS decision. In particular, product inspections conducted by industry associations, agricultural cooperatives, or farmer themselves curb the adoption of the TFH-TPS, whereas government inspection has no statistically significant effect. Farmers who sell green foods are less likely but organic farmers are more likely to adopt the OFH-TPS, which echoes the expectation based on the theoretical model. We also find that training of pesticide applications reduce the adoption of the OFH-TPS, but the perceived adverse effects of pesticide applications have no statistical effects. Furthermore, farmers who uses highly toxic and banned pesticides and/or who perceive poor food safety of the local markets are more likely to adopt the OFH-TPS. This study provides rich policy implications. First, calling the engagement of private sector to safeguard food safety and improving the efficacy of government inspection are critical to improve food safety. Second, education on pesticide applications is critical, especially among retailers of pesticides.

We identify two different contributions to both in-plane and out-of-plane magnetoresistivities. The first contribution has the same sign as the temperature coefficient of the resistivity \partial ln(ρ_i)/\partial T (i={c,ab}). This contribution reflects the incoherent nature of the out-of-plane transport. The second contribution is positive, quadratic in field, with an onset temperature that correlates to the antiferromagnetic ordering.

description: The low luminosity, X-ray flaring activity, of the sub-class of high mass X-ray binaries called Supergiant Fast X-ray Transients, has been investigated using XMM-Newton public observations, taking advantage of the products made publicly available by the EXTraS project. One of the goals of EXTraS was to extract from the XMM-Newton public archive information on the aperiodic variability of all sources observed in the soft X-ray range with EPIC (0.2-12 keV). Adopting a Bayesian block decomposition of the X-ray light curves of a sample of SFXTs, we picked out 144 X-ray flares, covering a large range of soft X-ray luminosities (1e32-1e36 erg/s). We measured temporal quantities, like the rise time to and the decay time from the peak of the flares, their duration and the time interval between adjacent flares. We also estimated the peak luminosity, average accretion rate and energy release in the flares. The observed soft X-ray properties of low-luminosity flaring activity from SFXTs is in qualitative agreement with what is expected by the application of the Rayleigh-Taylor instability model in accreting plasma near the neutron star magnetosphere. In the case of rapidly rotating neutron stars, sporadic accretion from temporary discs cannot be excluded.

The measured force shows the required periodicity corresponding to the corrugations. It also exhibits the necessary inverse fourth power distance dependence. The obtained results are shown to be in good agreement with a complete theory taking into account the imperfectness of the boundary metal. This demonstration opens new opportunities for the use of the Casimir effect for lateral translation in microelectromechanical systems.

description: Gilbert damping is a key property governing magnetization dynamics in ordered magnets. We present a theoretical study of intrinsic Gilbert damping induced by magnon decay in antiferromagnetic metals through $s$-$d$ exchange interaction. Our theory delineates the qualitative features of damping in metallic antiferromagnets owing to their bipartite nature, in addition to providing analytic expressions for the damping parameters. Magnon-induced intraband electron scattering is found to predominantly cause magnetization damping, whereas the Néel field is found to be damped via disorder. Depending on the conduction electron band structure, we predict that magnon-induced interband electron scattering around band crossings may be exploited to engineer a strong Néel field damping.

description: Abstract

Monitoring and Evaluation (M&E) systems play a critical role in assessing the performance and impact of non-governmental organizations (NGOs). This study examines the factors influencing the performance of M&E systems in NGOs in Garowe, Puntland, Somalia. The research explores key determinants such as organizational structure, human capacity, management involvement, and stakeholder participation in shaping the effectiveness of M&E systems.

Using a mixed-methods approach, data was collected through structured questionnaires and interviews with M&E professionals, project managers, and stakeholders. The findings reveal that human capacity, particularly staff expertise and education levels, significantly impact M&E system efficiency. Additionally, strong management support and stakeholder engagement contribute to better decision-making and accountability. However, challenges such as limited resources and inconsistent methodologies hinder optimal M&E performance.

The study concludes that strengthening M&E capacity through targeted training, increased resource allocation, and enhanced stakeholder collaboration is essential for improving M&E effectiveness. Recommendations include adopting technology-driven solutions, fostering a culture of learning within NGOs, and ensuring alignment between M&E practices and organizational objectives. This research provides valuable insights for policymakers, NGO leaders, and development practitioners seeking to enhance the role of M&E in project implementation and impact assessment.
What heavy quanta bounds could be inferred from a Higgs discovery?

description: The Higgs couplings can receive non-decoupling corrections due to heavy quanta, and deviations from the SM can be used to test its presence. The possible Higgs signal recently reported at LEP, with mh=115 GeV, severely constrains the presence of heavy quanta, such as a heavy fourth family. At Tevatron, the Higgs production by gluon fusion, followed by the decay h -> WW*, can also be used to probe the existence of heavy colored particles, including additional families, chiral sextet and octet quarks. Within the MSSM, we also find that gluon fusion is a sensitive probe for the squark spectrum.

description: There is widespread professional consensus that agricultural research and development (R&D) receives high economic returns, though there is also concern that these returns have been declining over the past few decades and unevenly distributed among different regions in the world. This study attempts to reveal both the time trend (i.e., increasing or decreasing) and regional developmental differences in the reported returns to agricultural R&D. Using a newly updated and expanded global database of estimated returns to agricultural R&D and a robust statistical methodology, our findings suggest that after accounting for methodological changes and other study factors that have varied over time, the contemporary returns to agricultural R&D investments are as high as ever. Furthermore, this study provides evidence that regional developmental differences are attributable to more than differences in the focus of research, researcher or research methodology.

description: Complex networks are a powerful paradigm to model complex systems. Specific network models, e.g., multilayer networks, temporal networks, and signed networks, enrich the standard network representation with additional information to better capture real-world phenomena. Despite the keen interest in a variety of problems, algorithms, and analysis methods for these types of network, the problem of extracting cores and dense structures still has unexplored facets. In this work, we present advancements to the state of the art by the introduction of novel definitions and algorithms for the extraction of dense structures from complex networks, mainly cores. At first, we define core decomposition in multilayer networks together with a series of applications built on top of it, i.e., the extraction of maximal multilayer cores only, densest subgraph in multilayer networks, the speed-up of the extraction of frequent cross-graph quasi-cliques, and the generalization of community search to the multilayer setting. Then, we introduce the concept of core decomposition in temporal networks; also in this case, we are interested in the extraction of maximal temporal cores only. Finally, in the context of discovering polarization in large-scale online data, we study the problem of identifying polarized communities in signed networks. The proposed methodologies are evaluated on a large variety of real-world networks against na\"ıve approaches, non-trivial baselines, and competing methods. In all cases, they show effectiveness, efficiency, and scalability. Moreover, we showcase the usefulness of our definitions in concrete applications and case studies, i.e., the temporal analysis of contact networks, and the identification of polarization in debate networks.

description: Water resources in the arid west and other parts of the world are becomingly increasingly scarce as population growth and water quality impairment puts new demands on this limited resource. With those increasing demands comes an increasing urgency to conserve water and to consume the resource more efficiently throughout the myriad of uses. Indeed, much of the conservation pressure comes down to agriculture, as this sector is allocated as much as 80% of the water available in states like Colorado; water is often over-appropriated and yet population is projected to double by the year 2050. Complicating this resource management problem is a very complex institutional rights structure, which can vary from basin to basin. In this study, we use a dynamic programming approach to examine how agricultural producer technology adoption decisions with uncertain water supplies are influenced by existing water rights systems, including prior appropriation and the ubiquitous “Beneficial Use Doctrine.” We find that imperfect property rights and uncertainty over water availability decrease the incentive to adopt water-saving technology.

description: The expressions for dynamical masses of quarks in the chiral limit in QCD in a strong magnetic field are obtained. A low energy effective action for the corresponding Nambu-Goldstone bosons is derived and the values of their decay constants as well as the velocities are calculated. The existence of a threshold value of the number of colors $N^{thr}_c$, dividing the theories with essentially different dynamics, is established. For the number of colors $N_c \ll N^{thr}_c$, an anisotropic dynamics of confinement with the confinement scale much less than $Λ_{QCD}$ and a rich spectrum of light glueballs is realized. For $N_c$ of order $N^{thr}_c$ or larger, a conventional confinement dynamics takes place. It is found that the threshold value $N^{thr}_c$ grows rapidly with the magnetic field [$N^{thr}_c \gtrsim 100$ for $|eB| \gtrsim (1{GeV})^2$]. In contrast to QCD with a nonzero baryon density, there are no principal obstacles for checking these results and predictions in lattice computer simulations.

On the derivation of a high-velocity tail from the Boltzmann-Fokker-Planck equation for shear flow

description: Uniform shear flow is a paradigmatic example of a nonequilibrium fluid state exhibiting non-Newtonian behavior. It is characterized by uniform density and temperature and a linear velocity profile $U_x(y)=a y$, where $a$ is the constant shear rate. In the case of a rarefied gas, all the relevant physical information is represented by the one-particle velocity distribution function $f({\bf r},{\bf v})=f({\bf V})$, with ${\bf V}\equiv {\bf v}-{\bf U}({\bf r})$, which satisfies the standard nonlinear integro-differential Boltzmann equation. We have studied this state for a two-dimensional gas of Maxwell molecules with grazing collisions in which the nonlinear Boltzmann collision operator reduces to a Fokker-Planck operator. We have found analytically that for shear rates larger than a certain threshold value the velocity distribution function exhibits an algebraic high-velocity tail of the form $f({\bf V};a)\sim |{\bf V}|^{-4-σ(a)}Φ(ϕ; a)$, where $ϕ\equiv \tan V_y/V_x$ and the angular distribution function $Φ(ϕ; a)$ is the solution of a modified Mathieu equation. The enforcement of the periodicity condition $Φ(ϕ; a)=Φ(ϕ+π; a)$ allows one to obtain the exponent $σ(a)$ as a function of the shear rate. As a consequence of this power-law decay, all the velocity moments of a degree equal to or larger than $2+σ(a)$ are divergent. In the high-velocity domain the velocity distribution is highly anisotropic, with the angular distribution sharply concentrated around a preferred orientation angle which rotates counterclock-wise as the shear rate increases.

description: The Kansas grain storage, handling and transportation industry has undergone considerable change in recent years in terms of physical storage and handling capacity, competitive organization of participants, and access to large scale rail transportation. Ongoing consolidation of local and regional cooperatives has occurred as have strategic investments in high-volume rail transportation facilities by both cooperatives and independent agribusinesses. While the structure of the Kansas grain industry has been in a period of dynamic change over the last decade, the reasons are varied and somewhat interdependent. Periods of severe drought in western Kansas, establishment of ethanol processing plants in different parts of the state, the ongoing competitive presence of the Kansas cattle feeding industry and recent growth in dairy industries, the construction of 100 railcar-plus shuttle train grain handling facilities in strategic locations in the state (to ensure competitive rail access by local / regional grain elevators), and other changes have all occurred on a large scale since years 2007-2008.
Rethinking Metadynamics: from bias potentials to probability distributions

description: Metadynamics is an enhanced sampling method of great popularity, based on the on-the-fly construction of a bias potential that is function of a selected number of collective variables. We propose here a change in perspective that shifts the focus from the bias to the probability distribution reconstruction, while keeping some of the key characteristics of metadynamics, such as the flexible on-the-fly adjustments to the free energy estimate. The result is an enhanced sampling method that presents a drastic improvement in convergence speed, especially when dealing with suboptimal and/or multidimensional sets of collective variables. The method is especially robust and easy to use, in fact it requires only few simple parameters to be set, and it has a straightforward reweighting scheme to recover the statistics of the unbiased ensemble. Furthermore it gives more control on the desired exploration of the phase space, since the deposited bias is not allowed to grow indefinitely and it does not push the simulation to uninteresting high free energy regions. We demonstrate the performance of the method in a number of representative examples.

description: We study the process of squeezing of an ensemble of cold atoms in a pulsed optical lattice. The problem is treated both classically and quantum-mechanically under various thermal conditions. We show that a dramatic compression of the atomic density near the minima of the optical potential can be achieved with a proper pulsing of the lattice. Several strategies leading to the enhanced atomic squeezing are suggested, compared and optimized.

The Behavior of Judges under the Gambler’s Fallacy

Publisher: name: University of Chicago

Subjects: subject: Behavioral Economics
subject: Applied Microeconomics

description: Previous studies show that when making sequential decisions, current judgments are affected by proceeding ones and people may exhibit negative autocorrelation. I investigated the behavior of judges when making sequential performance evaluations in competitions to determine if there is a negative autocorrelation that is independent of the performers’ merits. I checked its compatibility with the interpretation of the gambler’s fallacy, where individuals underestimate the occurrence probability of the sequential streaks. I examined two empirical examples: synchronized swimming competition, and hip hop dance championship, leveraging data from the 2019 FINA World Aquatics Championships, and the 2019 Hip Hop Dance Championships, respectively. The findings suggest that generally, negative autocorrelation is significant and is consistent with the gambler’s fallacy, even after procedures such as dropping extreme scores and taking average scores. In these cases, the spontaneous adjustments backfire the goal of fairness. Thus, further improvements such as adjusting the scoring procedures or correcting judges’ erroneous beliefs are needed to mitigate the effect.
