description: The lack of confirmation for the existence of supersymmetric particles and Weakly Interacting Massive Particles (WIMPs) appeals to extension of the field of studies of the physical nature of dark matter, involving non-supersymmetric and non-WIMP solutions. We briefly discuss some examples of such candidates in their relationship with extension of particle symmetry and pattern of symmetry breaking. We specify in the example of axion-like particles nontrivial features of cosmological reflection of the structure and pattern of Peccei-Quinn-like symmetry breaking. The puzzles of direct and indiect dark matter searches can find solution in the approach of composite dark matter. The advantages and open problems of this approach are specified. We note that detailed analysis of cosmological consequences of any extension of particle model that provides candidates for dark matter inevitably leads to nonstandard features in the corresponding cosmological scenario. It makes possible to use methods of cosmoparticle physics to study physical nature of the dark matter in the combination of its physical, astrophysical and cosmological signatures.

description: Greater understanding of irrigator water trade decision-making processes provides insight into the efficient reallocation of water resources between competing uses. Water trade decisions are often modelled as single processes, although results in this paper suggest that sequential decision modelling is more appropriate. We devised a theoretical model of experienced and naïve irrigators based on the search literature, and observed sequential decision-making in water allocation trade decisions using sample-selection techniques. There is evidence of positive selection effects, which motivate different drivers for the decision to participate in water trade and the subsequent decision about how much water to buy or sell.

description: The countries competing for the world Raisin Market are Chile, Greece, Iran, South Africa, Turkey, and the United States. Raisin is one of the top Turkish export products. Turkish raisin sector is facing an increasing competition in international markets. The aim of this work is to explain the magnitude of the trade flows for raisin from Turkey and other exporting countries to its main importing countries. This objective has been reached by establishing an appropriate econometric model derived from an extended form of the “Gravity Model”. To apply gravity model, a panel data with the most important six exporters of raisin and their importing countries between the years of 1999- 2008 were set up. Panel data models estimated with pooled ordinary least squares and fixed effects model under some diagnostic tests. Finally, some proposals and suggestions are developed for increasing the international competitiveness of the raisin production.

description: Coupling between $σ$-bonding electrons and phonons is generally very strong. To metallize $σ$-electrons provides a promising route to hunt for new high-T$_c$ superconductors. Based on this picture and first-principles density functional calculation with Wannier interpolation for electronic structure and lattice dynamics, we predict that trilayer film LiB$_2$C$_2$ is a good candidate to realize this kind of high-T$_c$ superconductivity. By solving the anisotropic Eliashberg equations, we find that free-standing trilayer LiB$_2$C$_2$ is a phonon-mediated superconductor with T$_c$ exceeding the liquid-nitrogen temperature at ambient pressure. The transition temperature can be further raised to 125 K by applying a biaxial tensile strain.

description: The existence of stellar cusps in dense clusters around massive black holes is a fundamental, decades-old prediction of theoretical stellar dynamics. Yet, observational evidence has been difficult to obtain. With a new, improved analysis of high-angular resolution images of the central parsecs of the Galactic Center, we are finally able to provide the first solid evidence for the existence of a stellar cusp around the Milky Way’s massive black hole. The existence of stellar cusps has a significant impact on predicted event rates of phenomena like tidal disruptions of stars and extreme mass ratio inspirals.

description: We study the leading-twist quasi parton distribution function (quasi-PDF) and quasi generalize parton distribution (quasi-GPD) of the pion meson by using a spectator model. We consider the case the quasi functions are defined via inserting the matrix $γ^3$ in the spacial correlation functions. We obtain the analytical expressions for the quasi-PDF and quasi-GPD. The numerical results for them are calculated from the parameters obtained by fitting the model results to the known parametrization. Particularly, we investigate the hadron momentum dependence of the quasi functions as well as compare the quasi distributions to the standard functions at different hadron momentum. We find that in the region $x>0.2$, the quasi distribution are similar to the standard distributions in size and shape when the hadron momentum is larger than $2$ GeV. Our study thus supports the idea of using quasi distributions to obtain standard distributions.

description: Global climate anomalies affect world economies and primary commodity prices. One of the more pronounced climate anomalies is El Niño Southern Oscillation (ENSO). In this study I examine the relationship between ENSO and world commodity prices using monthly time series of the sea-surface temperature anomalies in the Nino 3.4 region, and real prices of thirty primary agricultural commodities. I apply smooth transition auoregressive (STAR) modelling techniques to assess causal inferences that could potentially be camouflaged in the linear setting. I illustrate dynamics of ENSO and commodity price behavior using generalized impulse-response functions.
Beyond the Coulson-Fischer point: Characterizing single excitation CI and TDDFT for excited states in single bond dissociations

description: Linear response time dependent density functional theory (TDDFT), which builds upon configuration interaction singles (CIS) and TD-Hartree-Fock (TDHF), is the most widely used class of excited state quantum chemistry methods and is often employed to study photochemical processes. This paper studies the behavior of the resulting excited state potential energy surfaces beyond the Coulson-Fisher (CF) point in single bond dissociations, when the optimal reference determinant is spin-polarized. Many excited states exhibit sharp kinks at the CF point, and connect to different dissociation limits via a zone of unphysical concave curvature. In particular, the unrestricted M$_S=0$ lowest triplet T$_1$ state changes character, and does not dissociate into ground state fragments. The unrestricted $M_S=\pm 1$ T$_1$ CIS states better approximate the physical dissociation limit, but their degeneracy is broken beyond the CF point for most single bond dissociations. On the other hand, the $M_S=\pm 1$ T$_1$ TDHF states reach the asymptote too soon, by merging with the ground state from the CF point onwards. Use of local exchange-correlation functionals causes $M_S=\pm 1$ T$_1$ TDDFT states to resemble their unphysical $M_S= 0$ counterpart. The 2 orbital, 2-electron model system of minimal basis H$_2$ is analytically treated to understand the origin of these issues, revealing that the lack of double excitations is at the root of these remarkable observations. The behavior of excited state surfaces is also numerically examined for species like H$_2$, NH$_3$, C$_2$H$_6$ and LiH in extended basis sets.

description: This study focuses on the pattern between investment in chemical inputs such as fertilizer, pesticides and herbicides and technical efficiency of farm households in Laguna, Philippines. Using a one‐stage maximum likelihood estimation procedure, the stochastic production frontier model was estimated simultaneously with the determinants of efficiency. Results show that farmers with a low technical efficiency score have a high investment share in chemical inputs. Farmers who invested more in chemical inputs relative to other variable inputs attained the same or even lower output and were less efficient than those farmers who invested less. The result shows that farmers who invested wisely in chemical inputs can encourage farmers to apply chemical inputs more optimally.
Vacuum stability of Froggatt-Nielsen models

description: We discuss vacuum stability in Froggatt-Nielsen (FN) models. One concern in FN models is that for large flavon VEVs the running of the quartic Higgs coupling is enhanced what might lead to a more severe instability compared to the Standard Model (SM). We study this issue using the renormalization-group improved scalar potential. Another issue is that the mixing between the Higgs and the flavon can potentially destabilize the potential. However, taking current bounds on the flavon phenomenology into account, we find that both effects do not lead to an instability that is more severe than in the SM.

description: We estimate the efficiency of groundwater use in cotton production in the Punjab province of Pakistan. We use a survey data of 189 cotton producers comprising 98 tube-well owners and 91 water buyers in order to get the differential impact of tube-well ownership on groundwater use efficiency. We use data envelopment analysis to compute the technical, scale, cost and allocative efficiencies for tube-well owners and water buyers relative to a meta-frontier and groupfrontiers. The DEA sub-vector and slack-based models are used to compute groundwater use efficiency. The results indicate low levels of technical inefficiencies with water buyers being more inefficient relative to tube-well owners. However, groundwater use inefficiency is more pronounced than the respective technical efficiency. The sub-vector and slack-based estimates are highly correlated suggesting the robustness of the results. The results on returns to scale indicate that the majority of cotton growers are operating at increasing returns to scale, suggesting that efficiency can be improved by expanding the scale of operation. We use a second-stage bootstrap truncated regression to investigate the factors that influence technical efficiency and groundwater use efficiency. We find that the level of education, seed quality and extension services have positive significant impacts on technical and groundwater use efficiency. We suggest that knowledge of crop water requirements and the use of improved crop varieties can play role in improving the efficiency of groundwater use.

description: The electrodynamics of Weyl semimetals (WSMs) is an extension of Maxwell's theory where in addition to field strength tensor $F_{μν}$, an axion field enters the theory which is parameterized by a four-vector $b^μ=(b_0,\bf b)$. In the tilted Weyl matter (TWM) an additional set of parameters ${\bfζ}=(ζ_x,ζ_y,ζ_z)$ enter the theory that can be encoded into the metric of the spacetime felt by electrons in TWM. This allows an extension of Maxwell's electrodynamics that describes electric and magnetic fields in TWMs and tilted Dirac material (TDM) when $b^μ=0$. The tilt parameter $\bfζ$ appearing as off-diagonal metric entries mixing time and space components mingles $\bf E$ and $\bf B$ fields whereby modifies the inhomogeneous Maxwell's equations. Surface plasmon polariton (SPP) in these systems describes the propagation of electromagnetic waves at the {\it interface of two different spacetime geometries}. In the case of TDM, we find a characteristic dependence of SPP spectrum on the tilt parameter $ζ$ which can be used map $ζ$ from SPP measurements. In the case of TWM, depending on whether the interface with vacuum supports a Fermi arc or not, and whether the propagation direction is along the Fermi arc or transverse to it, we find many unusual spectral features for SPP modes. Our detailed study of the dependence of SPP spectra on the arrangements of three vectors $(\bf b, q,ζ)$, the first two of which are at our control, can be utilized to map the tilt characteristics and Fermi arc characteristics from SPP measurements.

description: A long-term goal of exoplanet studies is the identification and detection of biosignature gases. Beyond the most discussed biosignature gas O$_2$, only a handful of gases have been considered in detail. Here we evaluate phosphine (PH$_3$). On Earth, PH$_3$ is associated with anaerobic ecosystems, and as such is a potential biosignature gas on anoxic exoplanets. We simulate CO$_2-$ and H$_2-$dominated habitable terrestrial planet atmospheres. We find that PH$_3$ can accumulate to detectable concentrations on planets with surface production fluxes of 10$^{10}$-10$^{14}$ cm$^{-2}$ s$^{-1}$ (corresponding to surface concentrations of 10s of ppb to 100s of ppm), depending on atmospheric composition and UV flux. While high, such surface fluxes are comparable to the global terrestrial production rate of CH$_4$ (10$^{11}$ cm$^{-2}$ s$^{-1}$) and below the maximum local terrestrial PH$_3$ production rate (10$^{14}$ cm$^{-2}$ s$^{-1}$). As with other gases, PH$_3$ can more readily accumulate on low-UV planets, e.g. planets orbiting quiet M-dwarfs or with a photochemical UV shield. If detected, PH$_3$ is a promising biosignature gas, as it has no known abiotic false positives on terrestrial planets that could generate the high fluxes required for detection. PH$_3$ also has 3 strong spectral features such that in any atmosphere scenario 1 of the 3 will be unique compared to other dominant spectroscopic molecules. PH$_3$'s weakness as a biosignature gas is its high reactivity, requiring high outgassing for detectability. We calculate that 10s of hours of JWST time are required for a potential detection of PH$_3$. Yet because PH$_3$ is spectrally active in the same wavelength regions as other atmospherically important molecules (e.g., H$_2$O and CH$_4$), searches for PH$_3$ can be carried out at no additional observational cost to searches for other molecules relevant to exoplanet habitability.

description: The eutrophication of Lake Tai in the mid-east of China caused by an excessive import of nutrients from agricultural non-point-source pollution impedes social and economic development. In our research we aim to improve the understanding of the farmers’ decision-making process applying chemical fertilizers. Based on data gained in household interviews in 2011 and 2012 we follow the question: Which factors influence the individual decision on the use of fertilizers? Our approach is twofold: first, we estimate a production function to assess nitrogen overuse. Second, based on qualitative data we analyse the influence of the institutional context on individual decision-making.

description: This paper considers micropolar media that can undergo structural changes and do not a priori consist of indestructible material particles. Initially the pertinent literature is reviewed. Then the necessary theoretical framework for a continuum of that type is presented. The standard macroscopic equations for mass, linear and angular momentum are complemented by a recently proposed balance for the moment of inertia tensor, which contains a production term. Two examples illustrate the effect of the production. In the first example, we study a continuous stream of matter on a conveyor belt going through a crusher so that the total number of particles will change. In context with this example, it is also clear that the traditional Lagrangian way of describing the motion of solids is no longer adequate and must be replaced by the Eulerian point of view known from fluid mechanics. The second example deals with hollow particles which rotate because of the presence of body couples. Now a transient temperature field is superimposed such that the moment of inertia field changes due to the thermal expansion of particles. This in turn results in rotational motion that is no longer constant but varies in space and time.

description: Addressing the competitive imbalances in the dairy sector, the High Level Group of dairy market experts proposed written formal contracts between raw milk producers and processors to improve the bargaining position of producers and to stabilize milk supply. However, exclusive contracts, where a farmer is obliged to deliver his whole production amount to one dairy only, may lead to the opposite effect as they may deter market entry of rival dairies. We develop a theretical model and show that an incumbent dairy can deter entry of a rival dairy when the farmer is risk averse.

description: Non-minimal hidden sectors are an important generic possibility and arise in highly motivated theories like Neutral Naturalness. A fraction of dark matter could therefore have hidden interactions analogous to Standard Matter (SM) electromagnetism and nuclear physics. This leads to the formation of \emph{Mirror Stars}: dark-sector analogues of regular stars that shine in dark photons. We examine the visible signatures of Mirror Stars in observations for the first time. If the dark and visible photon have a small kinetic mixing, SM matter is captured in Mirror Star cores, giving rise to an optical signal similar to but much fainter than white dwarfs, as well as a separate X-ray signal that represents a direct window into the Mirror Star core. This robust and highly distinctive signature is a smoking gun of Mirror Stars and could be discovered in optical and X-ray searches.

description: We study the fluctuations of systems modeled by Markov jump processes with periodic generators. We focus on observables defined through time-periodic functions of the system's states or transitions. Using large deviation theory, canonical biasing and generalized Doob transform, we characterize the asymptotic fluctuations of such observables after a large number of periods by obtaining the Markov process that produces them. We show that this process, called driven process, is the minimum under constraint of the large deviation function for occupation and jumps.

description: In this contribution it is argued and empirical proven, complementary to the existing literature, that distance to a trading partner especially in agricultural trade does not only reflect transport costs but also different areas of cultivation. The study accounts for the described patterns by modeling different areas of cultivation. Without doing so the effect of distance would be underestimated.

description: This Working Paper, the first deliverable of REUNIR Work Package 3, aims to understand the nature of the military threats facing the nine candidate countries of the Western Balkans and Eastern Neighbourhood.

We identify six military instruments that might be employed by third states against the candidate countries and from which threats—defined as functions of capabilities and intent to exploit vulnerabilities—may emerge. The six instruments are: armed attack, armed presence, sub-threshold attack, military training, arms transfers, and defense cooperation. We assess, on a low-medium-high scale, the likelihood that each of these instruments will be employed against each of the candidate countries in the 2025–2030 timeframe, and, also on a low-medium-high scale, the impact on the candidate countries should these threats emerge. These assessments—essentially expert judgments by the research team—were supported by reference to sets of likelihood and impact indicators developed for this project. They were further informed by a review of primary and secondary literature on the security environment of the candidate countries, as well as a small number of expert interviews. The resulting threat scans, included as an annex to this Working Paper, summarize the military threats to each candidate country.

description: I provide a stocktaking on the profile of regional trade agreements in the global trading system over the last decade focusing heavily on the period since the 2008 financial crisis and relying heavily on WTO notifications. Regional agreements cover both regional trade agreements and broader economic cooperation agreements, but exclude bilateral investment and tax treaties. I note the continued growth in the number of regional agreements, notified to the WTO, as evidence of the lack of reduced momentum in the growth of regional agreements. I temper this by noting that some of this continued growth reflects changes to existing agreements rather than de novo new agreements. Much of the growth is also in agreements between small economies. Finally, I note the recent prospects for new large-country to large-country agreements; especially the TPP, US-EU and Japan-Korea-China agreements. These are yet to be concluded and notified.

description: Low adoption of productive agricultural technologies is a puzzle. Agricultural extension services rely on external agents to communicate with farmers, although social networks are known to be the most credible source of information about new technologies. We conduct a large-scale field experiment on communication strategies in which extension workers are partnered with different members of social networks. We show that communicator actions and effort are susceptible to small performance incentives, and adoption rates vary by communicator type. Communicators who face conditions most comparable to target farmers are the most persuasive. Incorporating communication dynamics can enrich the literature on social learning.

description: Since the elimination algorithm of Fourier and Motzkin, many different methods have been developed for solving linear programs. When analyzing the time complexity of LP algorithms, it is typically either assumed that calculations are performed exactly and bounds are derived on the number of elementary arithmetic operations necessary, or the cost of all arithmetic operations is considered through a bit-complexity analysis. Yet in practice, implementations typically use limited-precision arithmetic. In this paper we introduce the idea of a limited-precision LP oracle and study how such an oracle could be used within a larger framework to compute exact precision solutions to LPs. Under mild assumptions, it is shown that a polynomial number of calls to such an oracle and a polynomial number of bit operations, is sufficient to compute an exact solution to an LP. This work provides a foundation for understanding and analyzing the behavior of the methods that are currently most effective in practice for solving LPs exactly.

 Material examined. RUSSIA: Fൺඋ Eൺඌඍ: o. Kunashir, okr. vlk. Mendeleeva, [no day, month], 1985, 1 ♀, S. Churkin leg. (ZMUM, genit. prep.).
 Remarks. This is another distinctive E. Palaearctic species of Anthomyza. RඈIJගඹൾκ (2020) has recently recognized its close relationship to some unnamed Anthomyza species found in Taiwan and established the A. flavosterna group to accommodate all these species. Currently, A. flavosterna is the only species of the group occurring outside Taiwan.
 Distribution. The species is probably restricted to the easternmost areas of the Palaearctic but it has not been recorded from continental Asia up to the present. It remains known only from Japan (Hokkaido, Honshu) (SඎൾඒඈඌIJං & RඈIJගඹൾκ 2003) and the Kuril archipelago (Kunashir I., Iturup I.), see RඈIJගඹൾκ (2009), RඈIJගඹൾκ & PඋඓIJංൻඈඋඈ (2016) and the record above.

description: This paper measured senior high school student's level of sleep quality and psychological well-being in a private university in the Philippines. This study utilized the descriptive - correlational research design. A stratified random sampling technique selected the 328 senior high school students. The data were collected using two standardized psychological instruments: the Pittsburgh Sleep Quality Index (PSQI) and Ryff's Scale of Psychological Well-Being (RPSWB), analyzed through descriptive and inferential statistics. The findings revealed a poor sleep quality and a moderate level of psychological well-being of senior high school students. Pearson product-moment correlation yielded a significant relationship between sleep quality and sex, year level, and academic strand; a significant relationship between psychological well-being and academic strand; and no significant relationship between sleep quality and psychological well-being. To conclude, students can attain a good level of psychological well-being despite poor sleep quality. Collaborative efforts of guidance counselors, school administrators, and teachers may help the senior high school students educate and develop their sleep hygiene practices.
