    Abstract Experiments on bargaining games have repeatedly shown that subjects fail to use backward induction, and that they only rarely make demands in accordance with the subgame perfect equilibrium. In a recent paper, we proposed an alternative model, termed 'economic harmony' in which we modified the individual's utility by defining it as a function of the ratio between the actual and aspired pay-offs. We also abandoned the notion of equilibrium, in favour of a new notion of 'harmony', defined as the intersection of strategies, at which all players are equally satisfied. We showed that the proposed model yields excellent predictions of offers in the ultimatum game, and requests in the sequential common pool resource dilemma game. Strikingly, the predicted demand in the ultimatum game is equal to the famous Golden Ratio (approx. 0.62 of the entire pie). The same prediction was recently derived independently by Schuster (Schuster 2017.

    Abstract The present paper utilizes the recently proposed Complete Relativity Theory (CR) for the prediction of a neutrino velocity in a prototypical neutrino velocity experiment. The derived expression for the relative difference of the neutrino velocity with respect to the velocity of light is a function of the anticipation time t, the traveled distance D and the light velocity c, measured on Earth. It is independent neither on the traveling particle type nor on its energy level. With regard to fast neutrinos it is shown that the derived equation predicts with precision the results reported by OPERA, MINOS, and ICARUS. Since CR postulates that all physical entities, including the velocity of light, are relativistic entities, it follows that even though the results of the aforementioned experiments fail to support the neutrino superluminality claim, their precise prediction based on a theory that diametrically opposes SR, provides strong evidence for the inadequacy of SR in accounting for the dynamics of quasi-luminal particles. The aforementioned notwithstanding, a direct calculation of SR’s predictions for the above mentioned studies yields grossly incorrect results.

    Abstract Dark energy and dark matter constitute about 95% of the Universe. Nonetheless, not much is known about them. Existing theories, including General Relativity, fail to provide plausible definitions of the two entities, or to predict their amounts in the Universe. The present paper proposes a new special relativity theory, called Complete Relativity theory (CR) that is anchored in Galileo’s relativity, but without the notion of a preferred frame. The theory results are consistent with Newtonian and Quantum mechanics. More importantly, the theory yields natural definitions of dark energy and dark matter and predicts the content of the Universe with high accuracy

    Abstract We propose an epistemic theory of micro-economic interactions, termed Economic Harmony. In the theory, we modify the standard utility, by changing its argument from the player’s actual payoff, to the ratio between the player’s actual payoff and his or her aspired payoff. We show that the aforementioned minor epistemic modification of the concept of utility is quite powerful in generating plausible and successful predictions of experimental results, obtained in the standard ultimatum game, and the sequential common pool resource dilemma (CPR) game. Notably, the cooperation and fairness observed in the studied games are accounted for without adding an other-regarding component in the players’ utility functions. For the standard ultimatum game, the theory predicts a division of φ and 1 − φ, for the proposer and responder, respectively, where φ is the famous Golden Ratio (≈0.618), most known for its aesthetically pleasing properties. We discuss possible extensions of the proposed theory to repeated and evolutionary ultimatum games.

    Abstract Experiments using the public goods game have repeatedly shown that in cooperative social environments, punishment makes cooperation flourish, and withholding punishment makes cooperation collapse. In less cooperative social environments, where antisocial punishment has been detected, punishment was detrimental to cooperation. The success of punishment in enhancing cooperation was explained as deterrence of free riders by cooperative strong reciprocators, who were willing to pay the cost of punishing them, whereas in environments in which punishment diminished cooperation, antisocial punishment was explained as revenge by low cooperators against high cooperators suspected of punishing them in previous rounds. The present paper reconsiders the generality of both explanations. Using data from a public goods experiment with punishment, conducted by the authors on Israeli subjects (Study 1), and from a study published in Science using sixteen participant pools from cities around the world (Study 2), we found that: 1. The effect of punishment on the emergence of cooperation was mainly due to contributors increasing their cooperation, rather than from free riders being deterred. 2. Participants adhered to different contribution and punishment strategies. Some cooperated and did not punish ("cooperators"); others cooperated and punished free riders ("strong reciprocators"); a third subgroup punished upward and downward relative to their own contribution ("norm-keepers"); and a small sub-group punished only cooperators ("antisocial punishers"). 3. Clear societal differences emerged in the mix of the four participant types, with high-contributing pools characterized by higher ratios of "strong reciprocators", and "cooperators", and low-contributing pools characterized by a higher ratio of "norm keepers". 4. The fraction of "strong reciprocators" out of the total punishers emerged as a strong predictor of the groups' level of cooperation and success in providing the public goods.

    Abstract A young pregnant woman presented to the emergency department with acute lower abdominal pain. The ultrasound examination showed not only a viable fetus with a gestational age of 24 weeks but also a heteroechoic mass of about 7×7 cm involving parts of the face. The patient was found to be in active labour with rapid progression, and she gave birth to a dead female neonate. The autopsy showed a large malignant mixed tumour of the left parotid gland and revealed infection with cytomegalovirus. To our knowledge, this is the first reported case of a malignant mixed tumour of salivary glands in fetuses.

    Abstract Semen possesses a variety of antioxidant defense mechanisms which protect sperm DNA from the damaging effects of oxidative stress. Correlation between antioxidant genes variants and sperm DNA fragmentation (SDF) level is not sufficiently studied. Therefore, we investigated the association between several single nucleotide polymorphisms (SNPs): CYP1A1 (rs1048943A > G), CYP4F2 (rs2108622G > A), NRF2 (rs6721961C > A), PON1 (rs662A > G), NOS3 (rs1799983G > T), GSTM1 (null), CAT (rs1001179C > T), SOD2 (rs4880A > G), GSTP1 (rs1695A > G), PON2 (rs7493G > C), EPHX2 (rs1042064T > C), and AHR (rs2066853G > A) and elevated SDF. The study employed a case-control design where, the allele and genotype frequencies of the selected SNPs were compared between 75 semen samples with abnormal SDF (the cases) and 75 samples with normal SDF (the controls). DNA was extracted from the semen samples and allele-specific PCR (AS-PCR) was used for genotyping the SNPs. Relevant data were collected from the patients' records et al.-Basma Fertility Center. Suitable statistical tests and multifactorial dimensionality reduction (MDR) test were used to anticipate SNP-SNP interactions. Comparison of semen parameters revealed significant differences between cases and controls in terms of liquefaction time, sperm total motility, and normal form. Genotype frequencies of NOS3 G > T (GT), SOD2 A > G (AA and AG), EPHX2 T > C (CC and CT), and AHR G > A (GA and GG) were significantly different between cases and controls. Allele frequencies of SOD2 (G-allele), and EPHX2 (T-allele) also significantly varied between cases and controls. MDR analysis revealed that the NOS3, SOD2, and EPHX2 SNPs combination has the highest impact on SDF. The study findings suggest that genetic variations in genes involved antioxidant defenses contribute to abnormal SDF.

    Abstract Two experiments were conducted concurrently at the Horticultural Nursery of the Department of Crop Production, Federal University of Technology. Gidan Kwanu, Minna (latitude 6o 30’ N and Longitude 90 40’ E) during the dry season of 2016. The objective of the two trials was to determine the nutrient source and rates required in the production of beetroot (Beta vulgaris). The experimental treatment consists of three organic nutrient sources namely; cow dung, poultry manure and goat droppings at ratio by weight of 1:1:2 and 1:1:4 of sand: topsoil and organic nutrient. The experiments were laid arranged in completely randomized design.(CRD) and replicated thrice. Improved seeds of beetroot were soaked for 24 hours and sown at 3cm depth. Data were collected on growth parameters such as crop germination, crop vigor, plant height, number of offshoot, leaf area index, shoot girth, and fresh leafy yield. All data collected were subjected to analysis of variance (ANOVA) and the means were separated using Duncan multiple range test(DMRT). Result obtained indicated that 10t ha-1 poultry manure exhibited better growth performance of beetroot and resulted in higher fresh leafy yield than all other organic sources and rates. The study therefore recommends the application of poultry manure at the rate of 10 t ha-1 for beetroot farmers in the study area.
