Genetic diversity and genetic relatedness among 50 genotypes from eight countries, including Iran, Afghanistan, Turkmenistan, Syria, Lebanon, India, Yemen, and the United States located in two continents of Asia and the America, were assessed using SCoT markers. A total of 213 bands were produced; 100% of them were polymorphic; the average polymorphism information content (PIC) was 0.39. The mean Nei's gene diversity and Shannon's index were 0.33 and 0.49, respectively. Analysis of molecular variance suggested significant genetic differences within pomegranate populations. 99% of variance occurs within the populations, whereas 1% of the variation was recorded among the populations of pomegranate. Cluster analysis using SCoT markers able to group genotypes based on their geographical origins. Based on cluster analysis, the genotypes studied were divided into two main groups. The first group included most Asian genotypes, while American genotypes along with some Asian genotypes were in the second group. In the first group, Iranian genotypes were grouped with genotypes from Afghanistan and India. In the second group, the genotypes belonging to the America were in the same group as most of the genotypes of Turkmenistan. According to the present study, SCoT markers can be used to evaluate genetic diversity, identification and DNA fingerprinting pomegranate genotypes of different origins. This information can be used in breeding programs and the management of pomegranate collections.

We compare two welfare programs: the universal basic income (UBI) and negative income tax (NIT). Under a linear income tax system, we show that (i) the NIT can replicate the allocation of the UBI exactly by providing an identical marginal effective tax schedule, and (ii) the budget of the NIT is always smaller than that of the UBI. According to our quantitative model, which is calibrated to approximate the income and wealth distributions in the United States, the optimal UBI is to pay everyone 7.2% of the average income. We also show that the NIT can achieve a similar average welfare with a much smaller budget (2.3% of the GDP) by providing a subsidy that is generous to the very poor and quickly phases out as income increases.

Terrorists attacked the United States diplomatic compound and adjoining CIA Annex in Benghazi, Libya, on September 11, 2012. Despite repeated warnings from officials about the security risks in Tripoli and Benghazi, we argue that intelligence, security, and organizational deficiencies within the Department of State created vulnerabilities contributing to the deaths of four Americans, including Ambassador Christopher Stephens. Scholarly assessment of these failures has been precluded as a consequence of the incident’s use in partisan attacks. Republicans in Congress used investigations into the incident to damage presumed 2016 Democratic presidential nominee Hillary Rodham Clinton, who was then President Obama’s secretary of state. Setting aside political considerations and examining the failures that led to the attack is important to protect diplomatic personnel abroad in the future.

Diabetes mellitus (DM) is a common metabolic disease characterized by high blood sugar levels. It is well known that men with diabetes frequently experience reproductive disorders and sexual dysfunction. In fact, sperm quality has a significant effect on fertilization success and embryo development. The current study aimed to investigate the effect of Stevia rebaudiana hydroalcoholic extract on serum testosterone levels, sperm parameters, in vitro fertilization (IVF) success, and in vitro embryonic developmental potential to reach the blastocyst stage in a streptozotocin (STZ)-induced mouse model of diabetes. In this research, 30 male mice were distributed randomly into control, diabetic (streptozotocin 150 mg/kg) and diabetic + Stevia (400 mg/kg) groups. The results revealed a decrease in body and testis weight and elevated blood fasting blood sugar (FBS) levels in the diabetic group, compared with the control. However, Stevia treatment significantly increased body and testis weight, while serum FBS levels were decreased compared with the diabetic group. In addition, Stevia significantly increased blood testosterone levels compared with the diabetic group. Moreover, sperm parameters were improved considerably by Stevia treatment compared with the diabetic group. Furthermore, Stevia administration significantly promoted IVF success rate and in vitro development of fertilized oocytes compared with the diabetic group. In summary, our data indicated that Stevia enhanced sperm parameters, IVF success, and in vitro embryonic developmental competency in diabetic mice, probably because of its antioxidant effects. Therefore, Stevia could ameliorate sperm parameters that, in turn, increase fertilization outcomes in experimental-induced diabetes.

I argue that health insurance emerged as an important aspect of Nixon’s domestic policy agenda as a result of “policy escalation.” By policy escalation, I mean a cascading line of reasoning that causes policy makers focused on one apparently discrete issue to formulate approaches for dealing with other interconnecting policy areas. Policy escalation serves as an internal agenda-setting mechanism: as policy makers contemplate policy changes, they may attempt to imagine the ways in which change will affect the rationale, fiscal position, and execution of programs in other policy areas. In the case of health insurance, the Nixon administration’s proposal for replacing Aid to Families with Dependent Children with a guaranteed minimum income forced policy makers to consider how the new program would interact with the existing Medicaid program. Consideration of this question ultimately led them to formulate an approach to overhauling the nation’s entire health insurance system.

A distributed basic matching network (MN) designed method that can achieve multioctave bandwidth and highly efficient power amplifier (PA) for multiband applications is presented in this letter. The distributed network unit with a left-rotating T-type structure is employed to construct the wideband MN, whose topology and circuit parameters are acquired through optimization. Finally, the impedance realized by the designed MN falls into the target impedance region obtained by using multi-harmonic bilateral pull technique in the desired frequency band. For the proof of the method, a broadband highly efficient PA has been designed, fabricated, and measured using commercialized GaN high electron mobility transistors (HEMT). The measured results show that the implemented PA achieves a bandwidth of 137.8% from 0.7 to 3.8 GHz. The drain efficiency is between 59% and 70% with an output power of greater than 39 dBm and a gain ranging from 9 to 12.1 dB.

By examining two hypergeometric series transformations, we establish several remarkable infinite series identities involving harmonic numbers and quintic central binomial coefficients, including five conjectured recently by Z.-W. Sun [‘Series with summands involving harmonic numbers’, Preprint, 2023, arXiv:2210.07238v7]. This is realised by ‘the coefficient extraction method’ implemented by Mathematica commands.

Common examples of governance policies include regulations of lobbying, campaign-finance restrictions, and term limitations. Although the public generally favors these good-government reforms, the laws often restrict the autonomy of political elites. The histories of lobby reform in New York, Georgia, and Michigan illustrate how governance policies might be adopted despite elite opposition. In the states, initial reform efforts came about due to agenda-setting events or policy entrepreneurs. Although legislators adopted lobby reforms, they preferred transparency to other lobby reforms given its limited effect on mutualistic relationships. Initial lobby laws required only disclosure and did not restrict legislator–lobbyist interactions much. Only with the advent of additional events and entrepreneurs were the initial laws strengthened to limit interactions. The histories of reform imply that narratives of policy innovation or diffusion may be complicated somewhat by elite interests and that governance policies, once adopted, may have a unique immunity from repeal.

Christian-democratic parties not only constituted the most successful political force in much of Western Europe during most of the twentieth century; their attitudes toward solidaristic welfare reform have arguably also been more diverse than have those of most other major political groupings during this period. Whereas existing studies have mostly attributed this variation to electoral or strategic considerations, this article emphasizes the importance of interest group involvement. It analyzes and compares postwar old-age pension reform in three important Christian-democratic-ruled societies, Belgium, Germany, and the Netherlands, and shows how the very different attitudes of the main Christian-democratic parties toward solidaristic welfare reform in these countries related to the strength and unity of the Christian-democratic labor union movements there.

A mandate framework is proposed for delegating monetary policy to an instrument-independent, but goal-dependent central bank that emphasizes simplicity in both the objectives entering the welfare criterion and those in the instrument rule. It consists of: (i) a simple quadratic loss function penalizing deviations from target variables; (ii) a welfare-optimized, Taylor-type log-linear nominal interest-rate rule with targets that match those in the loss function; (iii) a zero-lower-bound (ZLB) constraint on the nominal interest rate imposing a low unconditional probability of ZLB episodes; and (iv) a long-run inflation target. In an estimated New Keynesian model with these features, we find that for a quarterly probability of 5%, an optimal annual inflation target is close to 2%, weights for real variables in the loss function are small compared with inflation except for the real wage growth mandate and the optimized rules mimic a price-level rule.

A synthetic flow angle sensor, able to estimate angle-of-attack and angle-of-sideslip, can exploit different methods to solve a set of equations modelling data fusion from other onboard systems. In operative scenarios, measurements used for data fusion are characterised by several uncertainties that would significantly affect the synthetic sensor performance. The off-line use of neural networks is not a novelty to model deterministic synthetic flow angle sensors and to mitigate issues arising from real flight applications. A common practice is to train the neural network with corrupted data that are representative of uncertainties of the current application. However, this approach requires accurate tuning on the target aircraft and extensive flight test campaigns, therefore, making the neural network tightly dependent on the specific aircraft. In order to overcome latter issues, this work proposes the use of neural networks to solve a model-free scheme, derived from classical flight mechanics, that is independent from the target aircraft, flight regime and avionics. It is crucial to make use of a training dataset that is not related to any specific aircraft or avionics to preserve the generality of the scheme. Under these circumstances, global and local neural networks are herein compared with an iterative method to assess the neural capabilities to generalise the proposed model-free solver. The final objective of the present work, in fact, is to select the neural technique that can enable a flow angle synthetic sensor to be used on board any flying body at any flight regime without any further training sessions.

During the 1940s, four US states established a new form of social insurance, Temporary Disability Insurance (TDI), meant to provide wage replacement to breadwinners unable to work due to nonoccupational illness or injury. The first TDI state, Rhode Island, did not initially exclude coverage of pregnancy-related disabilities, threatening the health of the TDI trust fund. Administrators and lawmakers then sought to reduce or eliminate the pregnancy-related disability benefit on the grounds that pregnancy and related conditions were not “real” disabilities. Subsequently, Rhode Island administrators advised lawmakers in California, New Jersey, and New York to exclude pregnancy-related disabilities from coverage. The breadwinner gender ideology animating New Deal social welfare programs intersected with gendered ideas of disability, creating a form of social insurance that excluded or marginalized pregnancy-related disability and further circumscribed women’s social citizenship.
