The West has been cutting its funding for Ukraine. Next year loans remain doubtful. European heavyweights have announced a reduction in funding for Ukraine. France, which promised 3 billion euros in aid to Ukraine this year, has cut it by 1 billion, or by one-third. This is due to budget problems — budget deficit for 2024 may amount to about six percent of France's GDP, which is unacceptable according to EU rules. French Defense Minister Sebastien Lecornu clarified in an interview with Politico that he did not plan to request additional funds for Kyiv from parliament until the end of this year.

The October 18 blackout paralyzed Cuba completely. The Cuban government tries to shrug the problem off by making references to the economic blockade, although the leadership of the island of freedom with no electricity should rather look at its own effectiveness. Total blackout in Cuba: three days without electricity and water Blackout, or apagon in Spanish, is a long-standing problem in Cuba that the island nation has been living with since the 1970s. Yet, this is the first time when the country experienced such a large-scale accident. On Friday, October 18, the Cuban electrical system was completely shut down as a result of an emergency at its main thermal power plant Antonio Guteras in Matanzas. This thermal power plant has not been modernized since 1988. The Cubans had to live without electricity and water for three days. All institutions and industries stopped and thus put the country's security in jeopardy.

Olaf Scholz's nerves gave out after Trump's victory. By saving Ukraine, the German Chancellor has ruined the ruling coalition of Germany and will now build it with the CDU, putting Germany's problems aside. Scholz ruins ruling coalition by saving Zelensky Germany's ruling coalition fell apart on Wednesday, November 6, after which Chancellor Olaf Scholz (SPD) fired Finance Minister Christian Lindner, who represented the Free Democratic Party (FDP) in the "traffic light" coalition. Three other FDP ministers resigned soon afterwards. Scholz plans to hold early elections in March, and his government will operate in a minority until then. The leader of the opposition CDU party, Friedrich Merz, demands that elections be scheduled for January.

In the last 15 years or so, since the first iPhone debuted all the way back in 2007, it’s not hyperbolic to suggest that smartphones have changed the very fabric of our society. The average teenager probably spends more time on their phone than off it and we all rely on them for business and pleasure, par-ticularly during those long and stressful commutes.

The Indian coronavirus strain, known as the delta variant or B.1.617, has four dangerous new symptoms, Express reports with reference to Abdul Ghafur, an infectious disease doctor from the Indian city of Chennai. According to the doctor, the symptoms of the delta variant of COVID-19 are similar to those of common cold: an infected individual develops a headache, runny nose and sore throat. Four new symptoms of the disease have been identified to date: diarrhea, hearing impairment, severe stomach disorders and blood clots that may lead to gangrene. Doctors note the new variant of the virus is unpredictable and state that any of the above symptoms could indicate an infection.

Smoking vapes and electronic cigarettes may lead to the development of a new lung disease that was dubbed as EVALI (E-cigarette and Vaping use-Associated Lung Injury). Research works to study EVALI slowed down with the onset of the coronavirus pandemic due to the similarity of symptoms, whereas the detection rate stopped growing, the Russian Health Ministry said. Symptoms of EVALI similar to those of COVID-19 Symptoms of the new disease are in many ways similar to symptoms of COVID-19. They include:

Small-angle-scattering tensor tomography is a technique for studying anisotropic nanostructures of millimetre-sized samples in a volume-resolved manner. It requires the acquisition of data through repeated tomographic rotations about an axis which is subjected to a series of tilts. The tilt that can be achieved with a typical setup is geometrically constrained, which leads to limits in the set of directions from which the different parts of the reciprocal space map can be probed. Here, we characterize the impact of this limitation on reconstructions in terms of the missing wedge problem of tomography, by treating the problem of tensor tomography as the reconstruction of a three-dimensional field of functions on the unit sphere, represented by a grid of Gaussian radial basis functions. We then devise an acquisition scheme to obtain complete data by remounting the sample, which we apply to a sample of human trabecular bone. Performing tensor tomographic reconstructions of limited data sets as well as the complete data set, we further investigate and validate the missing wedge problem by investigating reconstruction errors due to data incompleteness across both real and reciprocal space. Finally, we carry out an analysis of orientations and derived scalar quantities, to quantify the impact of this missing wedge problem on a typical tensor tomographic analysis. We conclude that the effects of data incompleteness are consistent with the predicted impact of the missing wedge problem, and that the impact on tensor tomographic analysis is appreciable but limited, especially if precautions are taken. In particular, there is only limited impact on the means and relative anisotropies of the reconstructed reciprocal space maps.

Rietveld refinements are widely used for many purposes in the physical sciences. Conducting a Rietveld refinement typically requires expert input because correct results may require that parameters be added to the fit in the proper order. This order will depend on the nature of the data and the initial parameter values. A mechanism for computing the next parameter to add to the refinement is shown. The fitting function is evaluated with the current parameter value set and each parameter incremented and decremented by a small offset. This provides the partial derivatives with respect to each parameter, along with information to discriminate meaningful values from numerical computational errors. The implementation of this mechanism in the open-source GSAS-II program is discussed. This new method is discussed as an important step towards the development of automated Rietveld refinement technology.

This work introduces X-Ray Calc (XRC), an open-source software package designed to simulate X-ray reflectivity (XRR) and address the inverse problem of reconstructing film structures on the basis of measured XRR curves. XRC features a user-friendly graphical interface that facilitates interactive simulation and reconstruction. The software employs a recursive approach based on the Fresnel equations to calculate XRR and incorporates specialized tools for modeling periodic multilayer structures. This article presents the latest version of the X-Ray Calc software (XRC3), with notable improvements. These enhancements encompass an automatic fitting capability for XRR curves utilizing a modified flight particle swarm optimization algorithm. A novel cost function was also developed specifically for fitting XRR curves of periodic structures. Furthermore, the overall user experience has been enhanced by developing a new single-window interface.

More targeted aircraft testing and simulation should be conducted to uncover design characteristics in new flight control systems that -- in rare circumstances -- may mislead pilots and result in unstable or dangerous flight conditions, says a new report by a National Research Council committee.

Scientific evidence links mold and other factors related to damp conditions in homes and buildings to asthma symptoms in some people with the chronic disorder, as well as to coughing, wheezing, and upper respiratory tract symptoms in otherwise healthy people, says a new report from the Institute of Medicine of the National Academies.

Evidence exists that people who lived or worked at Camp Lejeune Marine Base in North Carolina between the 1950s and 1985 were exposed to the industrial solvents tricholorethylene (TCE) or perchloroethylene (PCE) in their water supply, but strong scientific evidence is not available to determine whether health problems among those exposed are due to the contaminants, says a new report from the National Research Council.
