description: Managers of businesses that involve agricultural commodities need price forecasts in order to manage the risk in either the sale or purchase of agricultural commodities. Sometimes the most important forecasting component is simply whether the price will move up or down. Such binary forecasts are commonly referred to as qualitative forecasts. This paper examines whether qualitative forecasting of commodity prices can be improved by the inclusion within the model specification of price forecasts for other commodities. We use hog prices as a test case and find strong support for the inclusion of other commodity price forecasts in the best forecasting models. Unfortunately, the out-of-sample performance of these models is mixed at best. Still, the results suggest qualitative forecasts can be improved through the inclusion of other commodity price forecasts in our models.

description: This study examines the impact of hospitals on local labor markets in rural and urban counties. We measure the ability of hospitals, particularly in rural communities, to attract non-health related employment and provide higher wage jobs to residents based on their education level. Results find hospital employees with an associate’s degree can expect a 21.4% wage premium, when compared to alternative opportunities, and those with a bachelor’s degree can earn 12.2% more working in a hospital. Hospitals are shown to be positively related to overall employment as well as exhibit positive employment spill-over. For rural counties, a short-term general hospital is associated with 599 jobs in the county; 60 of which are hospital based and 499 are non-healthcare related. With the positive benefits on wages and non-healthcare job growth, hospitals have measurable positive labor market outcomes above their primary objective of providing health care access, particularly in rural counties.

DNA computing

description: After billions of years of evolution, nature gifts us versatile biological machines with complicated and robust behaviors. Can we understand and recapitulate the complexity of biology by de novo engineering biological systems? Can we integrate man-made knowledge or principles with the biology systems we try to build to achieve or go beyond the complexity of nature? The development of DNA nanotechnology has uncovered the uniqueness and the programmability of DNA molecules as a candidate for engineering complex molecular systems. The advances in the the field of DNA nanotechnology, such as building DNA computers, DNA therapeutic sensors, DNA amplifiers, DNA robots or DNA data storage are promising, yet the application is still in its infancy. This dissertation explores three topics. First of all, we engineer robust molecular information processing systems. We experimentally demonstrate a de novo engineered DNA cascade that is robust to errors. We theoretically analyze the taxonomy of low-error molecular cascades and the trade-offs between error and signal attenuation. We experimentally characterize different types of molecular interactions that lead to signal attenuation. Secondly, we develop in-memory and parallel computation with information stored in DNA. We theoretically design computation programs for binary counting and cellular automaton Rule 110, the latter of which is Turing universal. We experimentally establish the implementation of binary counting programs. Lastly, we experimentally program molecular computation at thermodynamic equilibrium. It is promising that the topics of the thesis will contribute to the further development of DNA nanotechnology.
HIGH-FAT DIET: THE EFFECTS OF SATURATED FAT TYPE

subject: Behavioural neuroscience

description: To combat the growing obesity pandemic, weight loss and maintenance are achieved primarily with dietary modification. One suggested modification is to replace saturated long-chain triglycerides (LCTs) with saturated medium-chain triglycerides (MCTs), as this reduces energy intake (Maher & Clegg, 2021), and can aid weight loss (He et al., 2024). Consistent with the human literature, in preclinical rodent models of high-fat diet (HFD)-induced obesity, shifting the HFD composition from LCTs to MCTs reduces overeating and weight gain (Ferreira et al., 2014). However, it is not fully understood how MCTs attenuate HFD-induced overeating and weight gain. According to one hypothesis, saturated fats, specifically LCTs, are overconsumed because they recruit activated microglia to the arcuate nucleus (ARC) (Salvi et al., 2024). Our central hypothesis is that MCT attenuate HFD-induced microgliosis in the ARC. To test this hypothesis, we performed three experiments to evaluate the effects of different MCTs on HFD-induced overeating, body weight gain, fat mass gain, lean mass gain, spontaneous alternations percentage in the y-maze, and microgliosis in the ARC and CA1. We found that LCT-rich HFDs did indeed induce overeating, body weight gain, and fat mass gain in both males and females. Fat mass gain, in particular, was greater in males than females. However, we found that LCT-rich HFDs did not decrease either total arm entries or spontaneous alternations in the y-maze. They also did not increase microgliosis in either the ARC or CA1 relative to chow-fed controls. However, there were a few methodological differences between these experiments and other studies that need to be resolved in order to properly test the hypothesis that MCTs attenuate HFD-induced microgliosis in the ARC. We also found that the replacement of LCT with MCT attenuated HFD-induced overeating, body weight gain, and fat mass gain. The attenuating effects were greater in C8/10 triglycerides than coconut oil. Collectively, these findings are consistent with the human literature regarding the effects of MCTs on body composition, indicating that C8/10 triglycerides are a better replacement for saturated LCTs than coconut oil to prevent body weight gain. However, future studies should compare C8/10 triglycerides to other, healthier, dietary fat options such as MUFAs and/or PUFAs to determine their clinical utility.

description: We introduce and study a toy model for anomalous transport and Griffiths effects in one dimensional quantum disordered isolated systems near the Many-Body Localization (MBL) transitions. The model is constituted by a collection of 1d tight-binding chains with on-site random energies, locally coupled to a weak GOE-like perturbation, which mimics the effect of thermal inclusions due to delocalizing interactions by providing a local broadening of the Poisson spectrum. While in absence of such a coupling the model is localized as expected for the one dimensional Anderson model, increasing the coupling with the GOE perturbation we find a delocalization transition to a conducting one driven by the proliferation of quantum avalanches which does not fit the standard paradigm of Anderson localization. In particular an intermediate Griffiths region emerges, where exponentially distributed insulating segments coexist with a few, rare resonances. Typical correlations decay exponentially fast, while average correlations decay as stretched exponential and diverge with the length of the chain, indicating that the conducting inclusions have a fractal structure and that the localization length is broadly distributed at the critical point. This behavior is consistent with a Kosterlitz-Thouless-like criticality of the transition. Transport and relaxation are dominated by rare resonances and rare strong insulating regions, and show anomalous behaviors strikingly similar to those observed in recent simulations and experiments in the bad metal delocalized phase preceding MBL. In particular, we find sub-diffusive transport and power-laws decay of the return probability at large times, with exponents that gradually change as one moves across the intermediate region. Concomitantly, the a.c. conductivity vanishes near zero frequency with an anomalous power-law.

description: The rapid spread of mobile information and communication technologies in Africa has spurred new hopes for agricultural development. In contrast to earlier initiatives that focused on technological assistance in the context of the “green revolution”, projects today increasingly rely on mobile phone applications, the use of tablets and different sensor technologies to enhance agricultural productivity and resilience. In light of the long history of technological approaches to agricultural development, in this contribution, we follow the idea of a “technological fix” and examine the agricultural futures associated with these new technologies. Drawing on a document analysis as well as ethnographic research at agricultural fairs, conferences, in an online course and on farms in Kenya and Tanzania, we will show how the (re)new(ed) belief in a “technological fix” becomes inscribed in the design of concrete events and projects. Focusing on the implications this has with regard to new actors, new visions and new mechanisms of agricultural development, we thus contribute to a better understanding of the specific ways in which agricultural futures are currently transformed, not just through new technologies but also through a new character of development practice associated with them.

description: We show that the BMN operators in D=4 N=4 super Yang Mills theory proposed as duals of stringy oscillators in a plane wave background have a natural quantum group construction in terms of the quantum deformation of the SO(6) $R$ symmetry. We describe in detail how a q-deformed U(2) subalgebra generates BMN operators, with $ q \sim e^{2 i π\over J}$. The standard quantum co-product as well as generalized traces which use $q$-cyclic operators acting on tensor products of Higgs fields are the ingredients in this construction. They generate the oscillators with the correct (undeformed) permutation symmetries of Fock space oscillators. The quantum group can be viewed as a spectrum generating algebra, and suggests that correlators of BMN operators should have a geometrical meaning in terms of spaces with quantum group symmetry.

description: There has been an increasing interest among economists in the impact of management practices on firm’s productivity. This paper explores how business practices affect firm productivity by using Vietnam’s bi-annual surveys of small firms conducted from 2006 to 2011. We constructed a simple weighted business practice index from 8 indicators. This index is simple but rather suitable for small and medium firms in developing countries. To examine the role of business practices in determining firm performance, production function and determinants of business practice adoption are estimated using the GMM-system method, which allows us to control for the endogeneity of production input, business practices index, and other factors. The results indicate that business practice index has a positive and statistically significant impact on firm productivity, employment and sales growth. As business practice index increases by 1 standard deviation (e.g. by 0.194 points over 1 and 0.173 points), the firm's value added increases by 19.1% to 24.0%. There is no evidence that the education level of the business owners/managers, percentage of employees with college degree on firm productivity. The results suggest that education may have indirect effects on productivity through business practice index. The effect of business practice on firm performance is found to vary across different sub-samples.. Both direct and indirect effects of competition lose their significance when we separately estimate production functions for each group of firms. We also find that for whole sample and for sole proprietorship businesses, the adoption of business practice in last period have a positive and statistically significant effects on the adoption of business practice in this period. However, total factor productivity (estimated from production function without business practice index) in the previous period does not have a strong impact on a firm’s adoption of business practice in this period while previous revenue and value added have a statistically significant impact.

The generators of the centralizer of $U_q(sl_2)$ in its three-fold product are naturally expressed through conjugations of Casimir elements with R. They are identified as the images of the generators of AW(3) under the embedding map by showing that they obey the AW(3) relations. This is achieved by introducing a natural coaction also constructed with the help of the R-matrix.

Thermosolutal and binary fluid convection as a 2 x 2 matrix problem

description: We describe an interpretation of convection in binary fluid mixtures as a superposition of thermal and solutal problems, with coupling due to advection and proportional to the separation parameter S. Many properties of binary fluid convection are then consequences of generic properties of 2 x 2 matrices. The eigenvalues of 2 x 2 matrices varying continuously with a parameter r undergo either avoided crossing or complex coalescence, depending on the sign of the coupling (product of off-diagonal terms). We first consider the matrix governing the stability of the conductive state. When the thermal and solutal gradients act in concert (S>0, avoided crossing), the growth rates of perturbations remain real and of either thermal or solutal type. In contrast, when the thermal and solutal gradients are of opposite signs (S<0, complex coalescence), the growth rates become complex and are of mixed type. Surprisingly, the kinetic energy of nonlinear steady states is governed by an eigenvalue problem very similar to that governing the growth rates. There is a quantitative analogy between the growth rates of the linear stability problem for infinite Prandtl number and the amplitudes of steady states of the minimal five-variable Veronis model for arbitrary Prandtl number. For positive S, avoided crossing leads to a distinction between low-amplitude solutal and high-amplitude thermal regimes. For negative S, the transition between real and complex eigenvalues leads to the creation of branches of finite amplitude, i.e. to saddle-node bifurcations. The codimension-two point at which the saddle-node bifurcations disappear, separating subcritical from supercritical pitchfork bifurcations, is exactly analogous to the Bogdanov codimension-two point at which the Hopf bifurcations disappear in the linear problem.

description: We have adapted classical molecular dynamics to study the structural and dynamical properties of amorphous silica surfaces. Concerning the structure, the density profile exhibits oscillations perpendicularly to the surface as observed in liquid metal surfaces and the pair correlation functions as well as the angle distributions show features (absent in the interior of the films) that can be attributed to the presence of 2-fold rings which are perpendicular to the surface. From the mean-squared displacement of the non bridging oxygen atoms we find that in the interior region they move perpendicular to the surface while they move parallel to it in the surface region.

description: We study a one-dimensional, nonequilibrium Potts-like model which has $q$ symmetric absorbing states. For $q=2$, as expected, the model belongs to the parity conserving universality class. For $q=3$ the critical behaviour depends on the dynamics of the model. Under a certain dynamics it remains generically in the active phase, which is also the feature of some other models with three absorbing states. However, a modified dynamics induces a parity conserving phase transition. Relations with branching-annihilating random walk models are discussed in order to explain such a behaviour.

description: The transverse spin effects may be helpful to distinguish between scalar (J^{PC}=0^{++}) or pseudoscalar (J^{PC}=0^{-+}) nature of the spin zero (Higgs) particle once discovered in future accelerator experiments. The correlations can manifest themselves e.g. in distribution of acollinearity angle of X^{+-} in decay chain H/A -> tau^+ tau^- ; tau^{+-} -> nu X^{+-}. This delicate measurement will require however reconstruction of the Higgs boson rest-frame. Then, questions of the combined detector-theoretical effects may be critical to establish reliability of the method. Appropriate Monte Carlo program is essential. In the present paper we extend the standard universal interface, of the TAUOLA tau-lepton decay library, to include the complete spin effects for tau leptons originating from the spin zero particle. As usual, the interface is expected to work with any Monte Carlo generator providing Higgs boson production, and subsequent decay into pair of tau leptons. Some example of numerical results and cross checks of the program, will be also given.

description: The HJET Polarized Atomic Hydrogen Gas Jet Target polarimeter (HJET) polarimeter was designed to measure the absolute polarization of the proton beams at the Relativistic Heavy Ion Collider. In these measurements, the small scattering angle elastic $pp$ single $A_N(t)$ and double $A_{NN}(t)$ spin analyzing powers can be precisely determined. The experimental accuracy achieved at HJET requires corrections to the $A_N(t)$ parametrization, conventionally used for such studies. In this paper we evaluate the corrections to the analyzing powers due to (i) the differences between the electromagnetic and hadronic form factors and (ii) the $m_p^2/s$ terms in the elastic spin-flip $pp$ electromagnetic amplitude. The corresponding alterations of the evaluated hadronic spin-flip amplitudes are about the same as the experimental uncertainties of the HJET measurements. The proposed corrections may have implications for the elastic $pp$ forward real-to-imaginary amplitude ratios $ρ$ determined in unpolarized $pp$ experiments.

description: The ALEPH data on hadronic tau-decay is throughly analysed in the framework of QCD. The perturbative calculations are performed in 1-4-loop approximation. The analytical properties of the polarization operators are used in the whole complex q^2 plane. It is shown that the QCD prediction for R_{tau} agrees with the measured value R_{tau} not only for conventional Lambda^{conv}_3 = (618+-29) MeV but as well as for Lambda^{new}_3 = (1666+-7) MeV. The polarization operator calculated using the renormgroup has nonphysical cut [-Lambda^2_3, 0]. If Lambda_3 = Lambda^{conv}_3, the contribution of only physical cut is deficient in the explanation of the ALEPH experiment. If Lambda_3 = Lambda^{new}_3 the contribution of nonphysical cut is very small and only the physical cut explains the ALEPH experiment. The new sum rules which follow only from analytical properties of polarization operators are obtained. Basing on the sum rules obtained, it is shown that there is an essential disagreement between QCD perturbation theory and the tau-lepton hadronic decay experiment at conventional value Lambda_3. In the evolution upwards to larger energies the matching of r(q^2) (Eq.(12)) at the masses J/psi, Upsilon and 2m_t was performed. The obtained value alpha_s(-m^2_z) = 0.141+-0.004 (at Lambda_3 = Lambda^{new}_3) differs essentially from conventional value, but the calculation of the values R(s) = sigma(e+e- -> hadrons)/sigma(e+e- -> mu+mu-), R_l = Gamma(Z -> hadrons)/Gamma(Z -> leptons), alpha_s(-3 GeV^2), alpha_s(-2.5 GeV^2) does not contradict the experiments.

description: The distribution of matter fluctuations in our universe is key for understanding the nature of dark matter and the physics of the early cosmos. Different observables have been able to map this distribution at large scales, corresponding to wavenumbers $k\lesssim 10$ Mpc$^{-1}$, but smaller scales remain much less constrained. The 21-cm line is a promising tracer of early stellar formation, which took place in small haloes (with masses $M\sim 10^6-10^8M_\odot$), formed out of matter overdensities with wavenumbers as large as $k\approx100$ Mpc$^{-1}$. Here we forecast how well both the 21-cm global signal, and its fluctuations, could probe the matter power spectrum during cosmic dawn ($z=12-25$). We find that the long-wavelength modes (with $k\lesssim40$ Mpc$^{-1}$) are highly degenerate with astrophysical parameters, whereas the modes with $k= (40-80)$ Mpc$^{-1}$ are more readily observable. This is further illustrated in terms of the principal components of the matter power spectrum, which peak at $k\sim 50$ Mpc$^{-1}$ both for a typical experiment measuring the 21-cm global signal and its fluctuations. We find that, imposing broad priors on astrophysical parameters, a global-signal experiment can measure the amplitude of the matter power spectrum integrated over $k= (40-80)$ Mpc$^{-1}$ with a precision of tens of percent. A fluctuation experiment, on the other hand, can constrain the power spectrum to a similar accuracy over both the $k=(40-60)$ Mpc$^{-1}$ and $(60-80)$ Mpc$^{-1}$ ranges even without astrophysical priors. The constraints outlined in this work would be able to test the behavior of dark matter at the smallest scales yet measured, for instance probing warm-dark matter masses up to $m_{\rm WDM}=8$ keV for the global signal and $14$ keV for the 21-cm fluctuations. This could shed light on the nature of dark matter beyond the reach of other cosmic probes.

description: Despite evidence on effectivity and WHO recommendations, continuous care during labor is not yet available for all women. Options such as doula support are being considered, but face barriers in accessibility. To explore other implementation options, the Continuous Care Trial looked at the provision of continuous care by maternity care assistants. Maternity care assistants are well-established care providers within Dutch maternity care, routinely involved in the final stages of labor and postpartum. This qualitative study is an addition to the Continuous Care Trial and explores women’s experiences with continuous care during labor by maternity care assistants in the Netherlands. Fourteen interviews were conducted, audio-recorded and transcribed verbatim for manifest content analysis, following the methodology of Graneheim and Lundman. The explored experiences were analyzed for evident similarities and differences. Findings were described in three themes: ‘Women’s experiences with continuous care,’ ‘Continuous care of maternity care assistants’ and ‘Perspectives on implementation.’ Noted facilitators include positive effects of continuous care, a larger role of the partner, and recognition of the professional background of the maternity care assistant. Barriers include difficulty to decide when and what kind support to ask for and lack of knowledge on the effectivity of continuous support.

description: Our main objective is exploring the association between widespread prosperity and the presence of the cooperative movement at the regional level in Italy between 2010 and 2019. We summarize the widespread prosperity through an index originally proposed by Sen (1976) and we then perform a panel regression showing that there is a positive and significant association between such an index and the presence of the cooperative movement as captured by the relative size of cooperative employees. We also detect that the cooperative movement contributes to the regional prosperity more through its employment than in terms of the added value it generates. Moreover, the size of the cooperative presence significantly concurs to explain some large differentials among Italian regions.

description: We study the effect of turbulent flow on the droplet growth in a cloud during the condensational phase. Using the air parcel model, we describe analytically how the distribution of droplets over sizes evolves at the different stages of parcel movement. We show that turbulent random walk superimposed on an accelerated ascent of the parcel make the relative width of droplet distribution to grow initially as $t^{1/2}$ and then decay as $t^{-3/2}$.

description: The propagation of two-color laser fields through optically thick atomic ensembles is studied. We demonstrate how the interaction between these two fields spawns the formation of co-propagating, two-color soliton-like pulses akin to the simultons found by Konopnicki and Eberly [Phys. Rev. A 24, 2567 (1981)]. For the particular case of thermal Rb atoms, exposed to a combination of a weak cw laser field resonant on the D1 transition and a strong, sub-ns laser pulse resonant on the D2 transition, simulton formation is initiated by an interplay between the 5s_{1/2} -- 5p_{1/2} and 5s_{1/2} -- 5p_{3/2} coherences which amplifies the D1 field at the arrival of the D2 pulse producing sech-squared pulse with a length of less than 10 microns. This amplification is demonstrated in a time-resolved measurement of the light transmitted through a thin thermal cell. We find good agreement between experiment and a model that includes the hyperfine structure of the relevant levels. With the addition of Rydberg dressing, quasi-simultons offer interesting prospects for strong photon-photon interactions in a robust environment.

description: Many risk management strategies, including hedging the price risk using forward or futures contracts require accurate forecasts of basis, i.e., spot price minus the futures price. Recent literature in this area has applied nonlinear time-series models, which are refinements of the linear autoregressive models that allow the parameters to transition from one regime to another. These parametric nonlinear models, however, involve complex estimation problems, and may diminish forecasting accuracy, especially in longer horizons. We propose using a semi-parametric, generalized additive model (GAM) that may improve the forecasting performance with its simplicity and flexibility while still accounting for nonlinearities in local prices and basis. Empirical results based on weekly futures and spot prices for North Carolina soybean and corn markets support evidence of nonlinear effects in basis. In general, generalized additive models seem to yield better forecasts of basis.

description: Several chemical reactions catalyzed by plasmonic nanoparticles show enhanced rates under visible-light-excitation of the localized surface plasmon resonance of the nanoparticles. But it has been argued that there is an associated photothermal effect that can complicate the analysis and/or interpretation of the nature of the role played by plasmon excitation. This Viewpoint discusses this dilemma and provides some best practices for accounting for photothermal contributions in plasmon-excitation-driven chemistry. A classification of plasmonic chemistry into plasmonic photocatalysis and plasmonic photosynthesis is also proposed. It is argued that photosynthetic reactions, which require a Gibb's free energy input, constitute an ultimate test of the non-thermal, photochemical action of plasmon excitation.

description: The magnetization process of the S=1 and 1/2 kagome Heisenberg antiferromagnet is studied by means of the numerical exact diagonalization method. It is found that the magnetization curve at zero temperature has a plateau at 1/3 of the full magnetization. In the presence of $\sqrt{3} \times \sqrt{3}$ lattice distortion, this plateau is enhanced and eventually the ferrimagnetic state is realized. There also appear the minor plateaux above the main plateau. The physical origin of these phenomena is discussed.

description: We have calculated the magnetic properties of substituted 3d-impurities (Cr-Ni) in a GaAs host by means of first principles electronic structure calculations. We provide a novel model explaining the ferromagnetic long rang order of III-V dilute magnetic semiconductors. The origin of the ferromagnetism is shown to be due to delocalized spin-uncompensated As dangling bond electrons. Besides the quantitative prediction of the magnetic moments, our model provides an understanding of the halfmetallicity, and the raise of the critical temperature with the impurity concentration.

description: Notes on Teloganodidae egg structure  Prior to this study, eggs of Teloganodidae were virtually unknown, having not been treated by Koss (1968) and Koss & Edmunds (1974) in their study of Ephemeroptera eggs, nor by McCafferty & Wang (1997; 2000) in their revision of Teloganodidae.
 Although only 5 among 13 Oriental species are now known in that stage, some general patterns may be drawn. All examined eggs lack chorionic attachment structures, compared, for instance, to those of most Ephemerellidae (Studemann et al. 1995; Studemann & Landolt 1997). They all possess a single polar cap, but the epithema is not uniform and is always comprised of two kinds of structures.
 Teloganodes eggs are pear-shaped and seem characterized by the presence of triangular, tooth-like structures arising from the chorion and delimiting the polar cap; the micropyle is located close to the polar cap and directed to the opposite pole. The threads of the epithema are non-coiled.
 Dudgeodes eggs are ovoid; the micropyle is located in the equatorial area and directed transversely to the egg axis. The threads of the epithema are non-coiled for part of them and coiled for those forming the lateral attachments. Dudgeodes hutanis possess a very peculiar structure on the pole opposite to the polar cap, whose function is unknown at the moment (secondary attachment structure? remains of a second polar cap?).
 Derlethina eggs are almost round, the micropyle is located near the polar cap and directed transversely to the egg axis. The threads of the epithema are all coiled.
 Based on the terminology of Koss and Edmunds (1974), the polar cap of Teloganodes and Dudgeodes would be intermediate between type I (non-coiled, single unit cap) and II (non-coiled, multi-unit cap), whereas Derlethina eggs are close to type III (multi-threaded coiled cap). Obviously, more detailed investigations are needed on the ultrastructure of Teloganodidae eggs.

description: Context. Fast Radio Bursts (FRBs) are millisecond-long bursts uniquely detected at radio frequencies. FRB 131104 is the only case for which a $γ$-ray transient positionally and temporally consistent was claimed. This high-energy transient had a duration of $\sim400$~s and a 15-150~keV fluence $S_γ\sim4\times10^{-6}$ erg $\mathrm{cm}^{-2}$. However, the association with the FRB is still debated. Aims. We aim at testing the systematic presence of an associated transient high-energy counterpart throughout a sample of the FRB population. Methods. We used an approach like that used in machine learning methodologies to accurately model the highly-variable Fermi/GBM instrumental background on a time interval comparable to the duration of the proposed $γ$-ray counterpart of FRB 131104. A possible $γ$-ray signal is then constrained considering sample average lightcurves. Results. We constrain the fluence of the possible $γ$-ray signal in the 8-1000 keV band down to $6.4 \times 10^{-7}$ ($7.1 \times 10^{-8}$) erg cm$^{-2}$ for a 200-s (1-s) integration time. Furthermore, we found the radio-to-gamma fluence ratio to be $η>10^{8}$ Jy ms erg$^{-1}$ cm$^2$. Conclusions. Our fluence limits exclude $\sim 94\%$ of Fermi/GBM detected long gamma-ray bursts and $\sim 96\%$ of Fermi/GBM detected short gamma-ray bursts. In addition, our limits on the radio-to-gamma fluence ratio point to a different emission mechanism from that of magnetar giant flares. Finally, we exclude a $γ$-ray counterpart as fluent as the one possibly associated with FRB 131104 to be a common feature of FRBs.
